Roller type blister machine:The working rule of the roller blister packing machines is quite simple. The forming film is heated and softened by the heating device. The blister is then sucked by the negative vacuum pressure on the roller forming molding roller, and therefore the filling device fills the packaged object into the blister, then passes through the roller type.The heat sealing device seals the single-sided adhesive-coated cover film on the surface of the blister material at an appropriate temperature and pressure and seals the packaged object within the blister.Roller plate blister sealing machineThe roller plate type blister packaging machine is developed with the foundation of a roller type and flat type blister packaging machine. That is, a flat type molding device is employed for blow molding (positive pressure forming), and a roll type sealing device is sealed, and its blister packaging machine working principle is essentially the same.Flat blister sealing machineThe working rule of the flat forming blister machine: The formed film is heated and softened by the flat heating device. The softened film is blown into a blister by using compressed gas within the flat forming device, and therefore the filling device fills the package into the blister.Then, it’s sent to the flat sealing device, and therefore the cover film is sealed with the formed film under suitable temperature and pressure, then the batch number is printed, and thus the broken line is pressed by the typing imprinting device. Finally, the punching device is punched into a predetermined size product section.

Blister Packing Machine Details  Blister packing machines are special machines that are used as unit-dose packaging for tablets, capsules, etc. The device has a  component of a bubble pack that may be a cavity or pocket made up of a formable film, usually a thermoformed plastic or cold-formed aluminum film. This usually features a lidding seal of aluminum foil.In other words, this is an electromechanical machine that has both moving and stationary parts that aid in packaging and sealing products in pre-formed cavities.The mechanical movements facilitate the formation of sized cavities on packaging material, filling, and sealing with appropriate materials.Using different packaging materials and principles of forming, Blister Packs could also be divided into three types：aluminum/plastic (thermoforming) bubble pack, aluminum/aluminum (cold forming) bubble pack, and aluminum/plastic/aluminum bubble pack.IntroductionThe product is specially designed for hospital dosage room, laboratory institute, health care product, middle-small pharmacy factory, and featured by compact machine body, easy operation, multi-function, stroke adjustable, long durability etc, it is suitable for the Alu-PVC package of medicine, food, electric parts etc. Aided forming Pre‐cutting Inspection and rejecting control systems.

ProblemFriction generated during the unwinding of the roll of thick plastic film creates static. These static charges attract contamination from the surrounding area onto the film. During the heating and forming of the film to produce the blisters, the contamination bonds to the plastic film, creating permanent inclusions and potential scrap.The warm plastic generates even more static charges as it cools. This will result in further contamination or filling issues. These issues can include contamination from operators such as hair or skin, or repelling of the product, for example medical tablets or powders, during the filling of the blister.The top sealing layer can also suffer with static issues. Statically charged products can be pulled out of the blister when applying an aluminium tamper seal, or contamination can be attracted to the plastic seal causing sealing issues or product rejection due to visible contamination.All of these problems can be avoided by controlling the static charges.SolutionRolls of material which are purchased and found to be already contaminated will need to be cleaned. A web cleaner, such as a Meech Non-Contact CyClean, mounted prior to thermoforming is ideal for removing and capturing contamination safely. An ionising air curtain such as a 957 or 959IPS will remove the contamination but will not capture it. However, static control products can be the solution where budget is limited or quality is not imperative.Controlling static charges during product packing will allow the product and clean blister packaging material to come together, preventing product misbehaviour and inclusion of contamination. This can be done using a long range ionising bar such as a Meech 929IPS or 971IPS.

When a cart is at rest and you want to get it moving, you are working against its starting resistance. When a cart is in motion and you want to keep it going, you are working against its rolling resistance. It's usually better for starting resistance and rolling resistance to be low because that means it take less effort to move the wheeled equipment around. In general, wheels that are larger and harder have lower starting and rolling resistance.Zhongshan Zhiqingsong Automatic Machinery Co., Ltd  is an efficientand technology enterprise.

 Pneumatic, semi-pneumatic and flat-free casters provide different levels of cushioning against shocks and vibration, and they also differ in their susceptibility to damage and their maintenance requirements:A pneumatic caster wheel has a rubber tire filled with pressurized air, making it more cushioned and quieter, but also susceptible to punctures and flats. Typically pneumatic wheels are used for low-speed, human-powered applications.Pneumatic wheels are filled with high-pressure air and have excellent shock absorption qualities. They are ideal for outdoor use over soft or hard ground. Easy rolling rubber tyres cushion fragile loads from bumps and provide a smooth ride when used at low speeds. They can be used on a number of different surfaces such as gravel and grass. You may see pneumatic wheels on a variety of outdoor equipment such as trolleys, wheelbarrows and even portable stages. These castors are popular with sporting clubs, event companies, catering, and even transport and logistics. Pneumatic castors are also suitable for indoor use.A semi-pneumatic caster wheel has a rubber tire with thick walls around a non-pressurized pocket of air, providing cushioning without the possibility of going flat.Semi-pneumatic caster wheels feature an extra thick, solid soft rubber tire on an industrial plastic center and are ideal for uneven floors indoors or on grass outdoors, but should not be used on sand or gravel surfaces. These wheels provide both vibration and shock absorption when traversing uneven, inconsistent or cracked flooring. The soft rubber tires on semi-pneumatic caster wheels contain carbon and will cause marking on floors if dragged.A flat-free caster wheel has a solid rubber or polyurethane wheel that still provides some cushioning.

Caster brakes and locks help control the mobility of the wheel in different ways: A caster brake prevents the wheel from turning, helping to keep the equipment in place. Caster brakes are not designed to stop moving equipment and are not intended to be used on ramps or inclines. A directional lock, also called a swivel lock, prevents the caster wheel from swiveling while still allowing it to roll, which is helpful for straight-line travel. A total lock prevents the caster wheel from swiveling and rolling, helping to immobilize the equipment.The words brakes and locks are often used interchangeably, so the words may imply different meanings to different people.  You want to clearly specify what type of lock or brake function you need.Casters with brakes stop the wheel from rotating.  Casters with locks prevent the swivel from rotating.  A total lock caster immediately secures both the wheel and the swivel at the same time. A directional lock caster, sometimes known as a “brake and steer” caster, allows the wheel to rotate freely but locks the swivel into a “straight ahead” position.  This is most commonly used on hospital casters and aids the user in straight tracking down long corridors.  Industrial casters often refer to directional locks as “position” locks.Total locks are generally found on light duty casters and medium duty casters.  Total Lock casters are a safety feature commonly used in medical facilities and other institutions.  Total lock casters have become more widely applied in industrial applications due to their success in other applications.Still, many wheel brakes are commonly referred to as locks, so clarity is important.  Sometimes it is easiest just to talk wit someone.  Humphries' staff can easily provide the type of brake or lock you need.

How to Measure the caster wheel  Pleaser refere to the picture  Caster Stem DimensionsFor the dimensions of a caster stem, measure the stem length, the stem diameter, the hole location and the hole diameter. When measuring, collect the following information for all casters:Overall heightWheel diameterWheel widthSwivel radius (the horizontal distance between the center of the raceway or kingpin and the furthest edge of the wheel)Unique dimensions will also need to be collected for each mounting type (plate, stem, bolt hole).Caster Mount TypeThere are three basic types of caster mount:Plate: Attaches using bolts through designated bolt holes in the top plate.Stem: Uses a stem as the attaching device.Bolt hole: Stemless caster where a standard bolt is inserted into the hole and bolted to the equipment.Zhongshan Zhiqingsong Automatic Machinery Co., Ltd  is an efficientand technology enterprise.
