Description

Technical Field

[0001] This utility model relates to the field of vacuum forming machine technology, specifically to a feeding device for a vacuum forming machine. Background Technology

[0002] A vacuum forming machine, also known as a thermoforming machine, is a machine that uses heated and plasticized thermoplastic plastic rolls such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging boxes, frames, and other products. It utilizes the vacuum suction generated by a vacuum pump to mold heated and softened thermoplastic plastic sheets such as PVC and PET into various shapes of vacuum covers, blister trays, and other products.

[0003] Currently used feeding devices for vacuum forming machines require feeding during the vacuum forming process. These devices mostly rely on clamping arms to directly hold the vacuum forming parts. This method can easily damage the surface of the vacuum forming parts, which in turn affects the subsequent vacuum forming process and reduces the production efficiency of the products.

[0004] In summary, this utility model solves the problems in the background art by designing a feeding device for a vacuum forming machine. Utility Model Content

[0024] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0025] A feeding device for a vacuum forming machine includes a vacuum forming machine body 1 and a support base 2 disposed at the bottom of the vacuum forming machine body 1. A heating plate 3 is disposed on the top of the vacuum forming machine body 1. A mounting frame 4 and an electric conveyor belt 5 are fixedly mounted on the top of the support base 2. A drive motor 401 is fixedly mounted on the right side of the mounting frame 4. A transmission screw 402 and a limiting rod 403 are disposed on the inner side of the mounting frame 4. A moving block 404 is sleeved on the outer surface of the transmission screw 402 and the limiting rod 403. A hydraulic rod 405 is mounted on the top of the moving block 404. A material plate 406 is disposed at the bottom of the moving block 404. An installation groove 407 is opened on the bottom surface of the material plate 406. An electric push rod 408 is disposed inside the installation groove 407. A support block 409 is fixedly mounted on the telescopic end of the electric push rod 408. A positioning post 410, a support spring 411, and a clamping plate 412 are disposed on one side of the support block 409.

[0026] Specifically, the heating plate 3 is slidably connected to the top surface of the vacuum forming machine body 1 via an electric slide rail;

[0027] In this embodiment, the heating plate 3 is mainly used to support the thermoformed parts and to allow them to enter the body 1 of the thermoforming machine for thermoforming operations via an electric slide rail.

[0028] Specifically, the output end of the drive motor 401 passes through the right side surface of the mounting bracket 4 and is fixed to the right end of the transmission screw 402. The outer surface of the transmission screw 402 is threadedly connected to the inner wall of the moving block 404. The outer surface of the limiting rod 403 is slidably connected to the inner wall of the moving block 404. The telescopic end of the hydraulic rod 405 passes through the top surface of the moving block 404 and is in fixed contact with the top surface of the material plate 406.

[0029] In this embodiment, the electric conveyor belt 5 is mainly used to transport the blister pack, the drive motor 401 is mainly used to rotate the transmission screw 402, causing the transmission screw 402 to drive the moving block 404 to move. With the limit rod 403 sliding against the moving block 404, the moving block 404 is ensured to drive the material plate 406 to move smoothly. The hydraulic rod 405 is mainly used to drive the material plate 406 to move vertically, so that the material plate 406 clamps the blister pack through the clamping plate 412 and transfers it to the heating plate 3, thus meeting the feeding requirements of the blister pack.

[0030] Specifically, the mounting groove 407 is symmetrically distributed about the bottom centerline of the material plate 406. The inner wall of the top of the mounting groove 407 extends to the top surface of the material plate 406. The outer surface of the clamping plate 412 is in contact with the inner wall of the mounting groove 407. One end of the positioning post 410 and the support spring 411 are fixed to the surface of the clamping plate 412. The other end of the support spring 411 is in contact with the support block 409. The other end of the positioning post 410 is movably attached to the front surface of the support block 409 and extends backward.

[0031] In this embodiment, the electric actuator 408 is mainly used to drive the support block 409, causing the support block 409 to bring the clamping plate 412 close to the blister part. With the combination of the positioning post 410 and the support spring 411, the clamping plate 412 and the blister part can be stably clamped, and the clamping plate 412 can be prevented from applying excessive clamping contact force to the blister part, thus reducing damage to the blister part.

[0032] The working process of this utility model is as follows: When using a feeding device for a vacuum forming machine, the vacuum forming part is transported to the bottom of the mounting frame 4 by the electric conveyor belt 5. Then, the drive motor 401 drives the transmission screw 402. Under the threaded transmission between the transmission screw 402 and the moving block 404, the moving block 404 moves smoothly along the outer surface of the limiting rod 403. At this time, the hydraulic rod 405 is activated, causing the telescopic end to move downwards and bringing the material plate 406 into contact with the vacuum forming part. Then, the electric push rod 408 is activated. 408 drives the support block 409 to move, and the support block 409 drives the clamping plate 412 to come closer to the blister part. During the contact process, the clamping plate 412 will drive the positioning post 410 to slide along the inner wall of the support block 409 and compress the support spring 411, thereby ensuring that the clamping plate 412 and the blister part are in stable contact. Finally, the drive motor 401 drives the transmission screw 402, causing the material plate 406 to move above the heating plate 3. Then, the electric push rod 408 is controlled to retract, so that the blister part comes into contact with the heating plate 3, thus completing the feeding operation of the blister part.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
