Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a cutting mechanism of a blister packaging machine. Background Art

[0002] Blister packaging machine is a special equipment for packaging materials. Its working principle is: after heating and softening plastic materials such as PVC, it is formed into blisters through a forming device, and then the material is filled into the blister through a loading mechanism, and the aluminum foil and the blister are heat-sealed through a heat-sealing mechanism to achieve product sealing. In order to facilitate the breaking of multiple groups of finished products, it is usually necessary to make cuts on the finished products to leave breaking marks. The defects of traditional equipment after cutting are as follows: 1. The cutting mechanism is set after the heat-sealing mechanism, that is, the cutting process is performed after the material is filled and the aluminum foil is heat-sealed. At this time, when cutting, the aluminum foil and the blister of the PVC material are cut at the same time. After the aluminum foil is cut, it cannot be guaranteed that the aluminum foil seals the material. In order to ensure the sealing of the material by the aluminum foil, it is necessary to set the edge flat plate area of ​​the single-plate blister (i.e. the area where there is no blister space) to be larger, and the aluminum foil is covered on the larger area of ​​the edge flat plate of the blister to achieve the sealing effect. However, this causes a large amount of waste of blister material and aluminum foil, and the size of the overall blister plate is also relatively large; 2. The structure of the traditional cutting mechanism is relatively complex, and the consistency of the cutting depth is difficult to guarantee. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a cutting mechanism of a blister packaging machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A cutting mechanism of a blister packaging machine comprises an upper pressing roller, which is rotatably arranged on an upper lifting seat, the upper lifting seat is connected to a lifting drive assembly, a lower roller is arranged below the upper pressing roller, the lower roller is transmission-connected to a motor, a bubble eye groove is opened on the outer side wall of the lower roller, and a plurality of groups of cutting knives are arranged on the lower roller, and the cutting mechanism and the loading mechanism are sequentially arranged along the conveying path of the blister film material, so that the cutting knife cooperates with the upper pressing roller to first perform cutting processing on the blister film material without material placed thereon.

[0006] The lifting drive assembly comprises a first cylinder, and a piston rod of the first cylinder is connected to the lifting seat.

[0007] One end of the upper pressure roller is connected to a first gear, and one end of the lower roller is connected to a second gear, and the first and second gears can mesh with each other.

[0008] The cutting mechanism of a blister packaging machine of the above technical solution can cut the blister film first by setting the cutting mechanism before the loading mechanism. Since there is no loading and heat sealing at this time, the cutting process will not cause damage to the aluminum foil, and under the premise of not considering the damage of the aluminum foil, the area of ​​the flat plate at the edge of the blister film can be effectively reduced, effectively saving the blister film material and aluminum foil, and the blister plate specifications are smaller; and the blister is cut first, and then covered with aluminum film after filling the material. Since the aluminum film is covered on the top, the sealing effect is very good. In addition, the overall structure of the equipment is simple, and the production and assembly are convenient. By setting the first and second gears for meshing transmission, the relative position between the upper pressure roller and the cutting knife can be accurately controlled, thereby ensuring the consistency of the cutting depth.

DETAILED DESCRIPTION

[0015] As shown in the figure, the utility model discloses a cutting mechanism of a blister packaging machine, including an upper pressing roller 3, which is rotatably arranged on an upper lifting seat 2, and the upper lifting seat 2 is connected to a lifting drive assembly. Specifically, the lifting drive assembly includes a first cylinder 1, and the piston rod of the first cylinder 1 is connected to the lifting seat 2. A lower roller 7 is arranged below the upper pressing roller 3, and the lower roller 7 is connected to the motor 6 in a transmission manner. Specifically, a first synchronous wheel 4 is connected to the lower roller 7, and a second synchronous wheel 5 is connected to the output end of the motor 6. The first and second synchronous wheels are driven by a synchronous belt (not shown in the figure). A bubble eye groove 9 is opened on the outer wall of the lower roller 7, and a plurality of groups of cutting knives 8 are arranged on the lower roller 7. A cutting mechanism and a loading mechanism 15 are arranged in sequence along the conveying path of the blister film material 12, so that the cutting knife 8 cooperates with the upper pressing roller 3 to first perform a cutting process on the blister film material 12 without placing the material. Further, one end of the upper pressure roller 3 is connected to a first gear 11, and one end of the lower roller 7 is connected to a second gear 10, and the first and second gears can mesh with each other. A feed guide seat is arranged at the feed end of the lower roller 7.

[0016] The working principle of the utility model is as follows: the blister film material 12 first passes through the cutting mechanism, the first cylinder 1 drives the upper lifting seat 2 to descend, so that the upper pressure roller 3 descends and presses the film material on the lower roller 7, at this time the first and second gears are meshed with each other, the motor 6 can drive the lower roller 7 to rotate, and drive the upper pressure roller 3 to rotate through the first and second gear transmission, the outer convex part formed on the blister film material enters the bubble eye groove 9, and at the same time the cutting knife 8 cooperates with the upper pressure roller 3 to perform cutting on the blister film material, the depth of the cutting is generally one-half of the blister film material, so as to facilitate the subsequent conveying, loading and heat sealing. After the cutting is completed, the blister film material is then loaded through the loading mechanism 15, and then sent to the heat sealing mechanism 16 for heat sealing with the aluminum foil to achieve the sealing operation of the material. The single-plate blister 14 cut by the above structure, its cutting edge 17 can be set closer to the bubble eye 18 position, thereby effectively reducing the specification size of the single-plate blister 14, thereby achieving the material saving of the blister film material and the aluminum foil. In addition, it should be noted that, although the aluminum foil is not cut after the blister plate is processed in the present application, since the aluminum foil itself is a material that is easy to tear, it will not interfere with the breaking of the finished product.

[0017] The structure of the utility model can perform the cutting process on the blister film first by setting the cutting mechanism before the loading mechanism. Since no loading and heat sealing are performed at this time, the aluminum foil will not be damaged during the cutting process. Under the premise that the aluminum foil damage does not need to be considered, the area of ​​the flat plate at the edge of the blister film can be effectively reduced, and the blister film material and aluminum foil can be effectively saved, and the specifications of the single-plate blister are smaller. At the same time, since the entire aluminum film is covered on it without cutting, the sealing effect is better. In addition, the overall structure of the equipment is simple, and the production and assembly are convenient. By setting the first and second gears for meshing transmission, the relative position between the upper pressure roller and the cutting knife can be accurately controlled, thereby ensuring the consistency of the cutting depth.
