Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to an extrusion molding device for vacuum forming machine production. 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 uses the vacuum suction generated by a vacuum pump to vacuum form various shapes of vacuum covers, blister trays, blister packs, etc., from heated and softened thermoplastic plastic sheets such as PVC and PET through molds.

[0003] Furthermore, the application document with publication number CN218557183U mentions an extrusion molding device for vacuum forming machine production. This device uses a fixing mechanism above the main body of the vacuum forming machine to fix the plastic film during the downward cutting process of the blade body, preventing the plastic film from moving. At the same time, a blade groove is provided above the fixing block, allowing the blade body to enter the blade groove, ensuring the cutting efficiency of the plastic film and avoiding incomplete cuts. This is beneficial for fixing the plastic film and improving cutting efficiency. Multiple mounting slots are provided below the lifting block, allowing the position of the blade body to be freely adjusted for cutting plastic films of different sizes. The lifting block and hydraulic rod are threadedly connected, allowing for flexible adjustment of the lifting block angle to perform cutting of other sizes. This facilitates quick changes in the position of the blade body and easy adjustment of its size. However, there are still some defects that need to be optimized.

The pressure plate assembly 5 includes a pressing plate 501, a third lead screw nut 502, a third lead screw 503, and a second drive motor 504. The plastic film limiting assembly 703 includes a fixed frame 705 and a limiting frame 706. The top of the limiting frame 706 is provided with a drive assembly 707. The interior of the fixed frame 705 is provided with a recess 708. The plastic film 103 passes through the input assembly 1.

The introduction of the CCD imaging component allows for real-time monitoring of the cutting area, ensuring cutting accuracy and product quality. The integrated design of the control panel and battery makes the operation of the entire device simpler and more intuitive, while ensuring portability and continuous working capability. An extrusion plate 501 is positioned on top of the cutting plate 401, and its bottom surface is equipped with an anti-slip pad. The second drive motor 504 and the third lead screw 503 are connected via a coupling. The design enhances stability and cutting effect during the extrusion process, preventing the plastic film from slipping and misaligning. The cutting plate 401 is set inside the slot 405 and is adapted to the slot 405. The position of the cutting plate 401 is opposite to the output port 104. The tight fit between the cutting plate and the slot ensures the smoothness of the cutting process and the flatness of the cutting edge. The relative design of the position of the cutting plate 401 and the output port allows the cut plastic film to fall directly into the output port, facilitating subsequent conveying and forming operations. One end of the first lead screw 303 and one end of the second lead screw 306 are respectively equipped with a third drive motor. The first lead screw box 302 and the second lead screw box 305 are cross-shaped.

This design improves the flexibility and precision of the cutter movement, making the cutting path more diverse and complex, meeting the cutting needs of different shapes and sizes. The two ends of the plastic film 103 are fixedly connected to two sets of rollers 106 respectively. Limiting rollers are provided at both ends of the frame 1 to limit the position of the plastic film 103. One end of the rotating roller shaft 105 is connected to the bracket 108 via a bearing seat. The fixed connection between the plastic film and the rollers ensures the stability and continuity of the plastic film during transmission. The design of the limiting rollers further restricts the position of the plastic film, preventing displacement and wrinkles. This design improves the transmission efficiency and cutting quality of the plastic film, providing a good foundation for subsequent forming operations. The fixed frame 705 and the limiting frame 706 are compatible and embedded. The fixed frame 705 is fixedly connected to the main body 7 of the vacuum forming machine. The fixed frame 705 is opposite to the conveyor belt assembly 6. The fixed frame 705 is U-shaped, and a pressure sensor is provided on one side wall of the inner side of the fixed frame 705. The embedded connection between the fixed frame and the limiting frame stably limits the position of the plastic film 103.

[0032] The working process of this utility model is as follows: When using this type of extrusion molding device for vacuum forming machine production, the plastic film 103 is first smoothly introduced into the interior of the cutting frame 104 through the input component 101. The other end is recovered through the coordinated action of the rotating roller 105 and the roller 106. The CCD imaging component monitors the cutting area in real time to ensure cutting accuracy. Driven by the hydraulic rod 301 and the lead screw transmission, the tool moving component 3 drives the electric circular knife 309 to move precisely in the X and Y axis directions to cut the plastic film 103. After the required size is cut, the electric push rod 402 drives the cutting plate downward. Simultaneously, the electric telescopic rod 404 drives the push plate 403 to push the processed plastic film 103 out of the output port 104 and into the conveyor belt assembly 6 and into the body of the vacuum forming machine 7. In the body of the vacuum forming machine 7, the plastic film 103 is placed on the recess 708 inside the limiting frame 706. At the same time, the drive assembly 707 drives the fixing frame 705 to move downward, limiting the overall position of the plastic film 103. Then, the heating assembly 702 enters to heat and soften the plastic film 103. After that, the heating assembly 702 withdraws. The upper cover pressure plate assembly 701 and the lower mold vacuum assembly 704 work together to complete the vacuum forming.
