Description

Technical Field

[0001] The utility model belongs to the technical field of blister machines, and in particular relates to a conveniently disassembled blister machine. Background Art

[0002] The blister machine, also known as the thermoplastic forming machine, is a machine that blister heats and plasticizes thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into packaging boxes, frames, and other products of various shapes. It uses the vacuum suction force generated by the vacuum pump to blister the softened thermoplastic plastic sheets through the mold into vacuum covers, blister trays, bubble shells, etc. of various shapes. Therefore, the blister machine at least includes a mold and a suction part that can suck air into the mold cavity. As the fields of plastic packaging used in our modern life are increasing, plastic materials of different sizes and shapes are needed. The plastic materials thermoformed by the molding machine greatly improve our work efficiency. During the thermoplastic process, the model is easily displaced when the model is pressurized, resulting in deformation of the mold of the product formed by the blister, resulting in a decrease in the qualified rate of the product. Since the traditional blister machine needs to replace different model parts when blistering materials of different sizes and models, it is time-consuming and labor-intensive to replace and it is difficult to complete the workload. Therefore, we propose a fast vacuum blister machine. Utility Model Content

The installation slot 150 is provided with two groups of column 190 slots, and the bottom of the connector 120 is also connected to the vertically downward column 190, and the column 190 extends into the column 190 slot; the external mold 130 is provided with a corresponding first spring installation slot 200, and both sides of the external mold 130 are provided with a clamping piece 220 that penetrates the first spring installation slot 200 inwardly, and the first spring is provided in the first spring installation slot 200, and the first spring is connected to the clamping piece 220 so that the clamping piece 220 is subjected to force inwardly. The column 190 is also provided with a connecting hole 230, and the end of the clamping piece 220 penetrates into the connecting hole 230 and forms abutment.

[0021] Specifically, the external mold 130 is detachably connected to the connector 120, and is magnetically connected through the negative magnetic patch 170 of the mounting slot 150 and the positive magnetic patch 160 on the outside of the connector 120, so that the external mold 130 forms a buffer force when the connector 120 slides up and down for assembly, thereby improving the stability of assembly by the staff. Initially, the first spring 210 is forced inward to push the clamping part 220 inward, and the clamping part 220 forms a clamping connection with the column 190. When the staff needs to better assemble the external mold 130, they pull out the clamping part 220, and the end of the clamping part 220 is separated from the connection hole 230 of the column 190 and shrinks into the external mold 130, and the whole slides downward to achieve the disassembly function. After the new external mold 130 is replaced, the size of the installation slot 150 of the external mold 130 remains unchanged, and only the external structure of the external mold 130 is changed. The external mold 130 is pushed so that the installation slot slides upward along the connector 120. When the connecting hole 230 and the clamping member 220 form the same horizontal line, the clamping member 220 is extended into the connecting hole 230 under the influence of the first spring, and the external mold 130 is fixed on the connector 120 to complete the assembly. With this structure, the external mold 130 can be quickly replaced, saving time and effort, and improving the working efficiency of the blister machine.

[0022] In another embodiment of the utility model, the clamping member 220 passes through the first spring 210, one end of the first spring 210 is connected to the outer wall of the clamping member 220, and the other end is connected to the inner wall of the first spring mounting groove 200 facing outward, and a push-pull handle 260 is provided at the front end of the clamping member 220, and a synchronization roller 270 is connected to the end of the clamping member 220, and the pointing direction of the synchronization roller 270 remains perpendicular to the direction of the clamping member 220, and the length of the synchronization roller 270 is longer than the width of the clamping member 220; the upper and lower ends of the inner side of the connecting hole 230 are both provided with convergence grooves 280 matching the length of the synchronization roller 270, and the synchronization roller 270 moves in the convergence groove 280, so as to limit the synchronization roller 270 and ensure that the clamping member 220 fully enters the connecting hole 230.

[0023] In another embodiment of the utility model, the cabinet 100 is further provided with a heating device 290, which is located directly below the external mold 130 for heating the plasticized plastic.
