Description

Technical Field

[0001] This utility model relates to a paper-plastic packaging machine, specifically to a forming device for the paper-plastic packaging machine. Background Technology

[0002] A paper-plastic packaging machine is a machine that packages items such as batteries and small hardware using blister packs and cardboard. For example, patent CN201710870973.4 discloses a paper-plastic packaging machine, which includes a preheating mechanism and a forming mechanism. After the plastic sheet passes through the preheating mechanism, it is formed into a blister pack by the forming mechanism. Then, a traction device pulls the blister pack forward. The traction device needs to contact the blister pack through a mold to provide friction. However, in the prior art, the mold needs to be configured separately for blister packs of different shapes and sizes, resulting in poor adaptability and increased additional costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a forming device for a paper-plastic packaging machine that does not require the installation of a traction device.

[0004] The forming device of this paper-plastic packaging machine includes a frame, on which a preheating mechanism and a forming mechanism are sequentially installed along the feeding direction. The forming mechanism is mounted on a movable seat, and a guide rail extending along the feeding direction is mounted on the frame. The movable seat is slidably disposed on the guide rail, and the movable seat is connected to a feeding power source that drives the movable seat to move.

[0005] A transverse cutting mechanism is installed on the movable seat. The transverse cutting mechanism includes a knife holder and a plurality of longitudinally arranged transverse cutting blades installed on the knife holder. A blister packing mechanism is installed on the frame. The blister packing mechanism is located in front of the forming mechanism, and the transverse cutting mechanism is located between the forming mechanism and the blister packing mechanism.

[0006] The preheating mechanism includes two preheating plates, one above the other, with a gap between them to allow the blister membrane to pass through.

[0007] The forming mechanism includes an upper forming mold and a lower forming mold for forming blister packs.

[0008] The blister packing mechanism includes a base, a blister packing mold, and a power source for the mold. The power source can drive the blister packing mold to press the blister pack onto the base.

[0009] A cutting mechanism is installed on the frame. The cutting mechanism is located in front of the bubble-pressing mechanism. The cutting mechanism includes a cutting blade and a cutting power source for the action of the longitudinal cutting blade.

[0010] According to the forming device of the paper-plastic packaging machine provided by this utility model, the plastic sheet is pulled forward by the movement of the forming mechanism, which eliminates the need for a traction device, reduces manufacturing costs and improves installation convenience.

[0012] Figure 2 This is a 3D view of the horizontal cutting mechanism;

[0013] Figure 3 This is a schematic diagram of the bubble-pressing mechanism. Detailed Implementation

[0014] like Figure 1 As shown, the forming device of this paper-plastic packaging machine includes a frame 1. A preheating mechanism 3 and a forming mechanism 4 are installed sequentially on the frame 1 along the feeding direction. The preheating mechanism 3 is used to heat the plastic sheet on the material roll 2, and then the forming mechanism 4 forms the heated plastic sheet to form a continuous blister.

[0015] In order to pull the plastic sheet forward, such as Figure 1 As shown, the molding mechanism 4 is mounted on the movable seat 9. A guide rail 10 extending along the feeding direction is mounted on the frame 1. The movable seat 9 is slidably mounted on the guide rail 10, and the movable seat 9 is connected to the feeding power source that drives the movable seat 9. The molding mechanism 4 includes an upper molding die and a lower molding die for molding the blister pack. When the upper molding die and the lower molding die are closed, the feeding power source drives the movable seat 9 to move along the guide rail 10. In this way, the upper molding die and the lower molding die of the molding mechanism 4 pull the plastic sheet forward, and the molding process is completed during the movement (or after the blister pack has cooled down). After the molding process is completed, the upper molding die and the lower molding die of the molding mechanism 4 open, and the feeding power source drives the molding mechanism 4 to reset, waiting for the next traction. With this structure, there is no need to install an additional traction device. Only the movement of the molding mechanism 4 is needed to traction the plastic sheet. Since the upper molding die and the lower molding die of the molding mechanism 4 are already pressing against the plastic sheet and are completely in contact with the plastic sheet, the pulling force is large enough.

[0016] In order to automatically complete the transverse cutting of the blister pack during the resetting process of the forming mechanism 4, a transverse cutting mechanism 5 is installed on the moving seat 9. Figure 2As shown, the transverse cutting mechanism 5 includes a blade holder 51 and multiple longitudinally arranged transverse cutting blades 50 mounted on the blade holder 51; a blister packing mechanism 6 is mounted on the frame 1, located in front of the forming mechanism 4, and the transverse cutting mechanism 5 is located between the forming mechanism 4 and the blister packing mechanism 6. Before the forming mechanism 4 resets, the blister packing mechanism 6 presses down the blister, and then the feeding power source drives the moving seat 9 to reset. In this way, the forming mechanism 4 and the transverse cutting mechanism 5 move back together. While the transverse cutting mechanism 5 moves back, the transverse cutting blades 50 perform transverse cutting on the blister. With this structure, the transverse cutting mechanism 5 does not need to be installed separately, thereby reducing the size of the equipment and reducing production costs.

[0017] The preheating mechanism 3 includes two preheating plates, one above the other, with a gap between them to allow the blister film to pass through. When the blister film (plastic sheet) passes between the preheating plates, it softens, making it easier for the forming mechanism 4 to form it.

[0018] like Figure 3 As shown, the blister packing mechanism 6 includes a base 60, a blister packing mold 61, and a mold power source 62. Driven by the mold power source 62, the blister packing mold 61 presses the blister pack onto the base 60. In this way, when the transverse cutting blade 50 cuts the blister pack transversely, it will not pull the blister pack.

[0019] Finally, it is worth mentioning that a cutting mechanism 7 is installed on the frame 1. The cutting mechanism 7 is located in front of the blister packing mechanism 6. The cutting mechanism 7 includes a cutting blade and a cutting power source for the movement of the longitudinal cutting blade. The cutting mechanism 7 cuts multiple rows of blister packs, which are then transferred to the next station by the robot arm 8.
