Analysis of the Functions of Aluminum-plastic Blister Packaging Machine Components

1. Aluminum-plastic blister packaging machine body: The body is mainly composed of a machine base and wall panels, which is the main body of the machine and supports all other parts.

2. Aluminum-plastic reel of aluminum-plastic blister packaging machine: including aluminum foil reel and plastic sheet reel. The drum is mainly composed of a drum body, inner and outer stators, brake rings and adjusting nuts. Both ends of the drum body are supported on the support shaft by rolling bearings, which are the rotating parts of the drum. When the plastic film or aluminum foil is pulled, the device is driven. The web on the drum rotates freely. The stator is divided into inner and outer stators. The sliding sleeve is on the outer cylindrical surface of the cylinder and fixed at any position of the cylinder by fixing screws to install and fix coils of different widths. The braking ring is set on the inner and outer cylindrical surfaces of the cylinder and is fixed on the support plate. It is the stationary part of the drum and is used to brake the cylinder. Tightening or withdrawing the four adjusting screws on the outer circumference of the brake ring can increase or decrease the braking force on the cylinder, so that the pulled film or aluminum foil can obtain the necessary tension. The adjusting nut is screwed on the support shaft and set on the inner cylindrical surface of the outer end of the cylinder, and is connected to the copper body with a bearing. When the cylinder rotates, turning the adjusting nut can make the cylinder move axially. Used to adjust the horizontal position of the material. The support shaft is fixed on the support plate, and the support plate is fixed on the fuselage, forming the support body of the drum.

3. Blister heater of aluminum-plastic blister packaging machine: The blister heater is mainly composed of an arc-shaped heat box, a far-infrared tube, a support shaft, etc. The upper end of the arc-shaped heat box is hinged on the support shaft and can swing around the axis. , close to the blister roller mold to radiate the heating material film when working, and swing away from the blister roller mold when not working. The far-infrared tube is installed in the heat box and is the heating element of this mechanism. The voltage of the two poles of the far-infrared tube is adjusted through an electronic voltage regulator to adjust the heat so that the film obtains the necessary softening temperature. The support shaft is fixed on the fuselage. Supporting the hot box, the positioner consists of a spring rod and a stopper, which are installed on the hot box and the body respectively for positioning the working position of the hot box.

4. Aluminum-plastic blister packaging machine blister roller mold: The key component of this machine, which cooperates with the blister heater and heat-sealing screen roller to complete the blister forming, hot-pressing and sealing processes. This part mainly consists of a rolling mold, a rolling mold shaft, a moon-shaped valve plate, and a vacuum and cooling system. The rolling mold is made of hard aluminum alloy, with bubble pockets distributed on the surface, and micro holes drilled at the bottom of the pocket. It is connected to the vacuum suction pipe through the moon-shaped valve plate, so that the plastic film passing through the bubble section is softened by radiation heating of the heater. , was sucked into a bubble. The rolling mold is set on the rolling mold shaft and tightened with a nut. When changing chemicals, just open the sealing end cover of the rolling mold and loosen the nut, and the rolling mold can be replaced. The roll mold shaft core is equipped with inlet and drainage channels. The cooling water enters the rolling mold through the water channel and plays a cooling role.

5. Aluminum-plastic blister packaging machine feeder: It is mainly composed of materials, troughs, disk brushes, roller brushes and DC motors. The materials are used to store medicines. Open the gate, the medicine will enter the material trough on its own, and then brush the medicine into the formed blister with the help of three disc brushes that rotate around the vertical axis. The three disc brushes rotate in a planetary pattern to increase the filling rate of the feeder; The brush rotates clockwise around the horizontal axis and is placed at the outlet of the feeder. The drugs on the film that cannot enter the blister are brushed into the blister or returned to the feeder.

6. Heat-sealing anilox roller of aluminum-plastic blister packaging machine: The heat-sealing anilox roller cooperates with the bubble roller mold to complete the heat-pressure sealing work of the film and aluminum foil. The heat-sealing anilox roller mainly compresses the spring and clutch of the anilox roller. It consists of a device and a bracket. Six heating tubes are installed in the anilox roller body. During operation, the anilox roller is heated, and then the hot melt adhesive on the surface of the heat-sealed aluminum foil is heated and melted. The square bearings at both ends of the anilox roller slide along the bracket. In the groove, a compression spring is used to pressurize the anilox roller. During operation, the anilox roller is brought close to the bubble roller mold, so that the heat-sealed film and the heated aluminum foil are hot-pressed and sealed. The clutch device includes a cam and a shift fork. The cam rotates counterclockwise. The square bearing moves to the right through the shift fork, and the pressure spring is compressed in reverse. The anilox roller leaves the suction roller mold. When no plastic film and aluminum foil enter or no When entering heat sealing at the same time, the anilox roller and the suction roller mold must avoid contact, otherwise the anilox roller and the suction roller mold may be damaged.
