Description

Technical Field

[0001] This utility model relates to the technical field of polytetrafluoroethylene (PTFE), and in particular to a PTFE film longitudinal stretching machine. Background Technology

[0002] In the production and processing of polytetrafluoroethylene (PTFE) films, longitudinal stretching is a key process for improving film performance and has a significant impact on the final quality of the film. However, some existing PTFE film stretching equipment suffers from several inconveniences during operation. On the one hand, the lack of effective and convenient fixing devices makes it difficult to securely fix both ends of the PTFE film during stretching, leading to slippage and misalignment, which affects the accuracy and uniformity of the stretching process. On the other hand, the design of the stretching mechanism is not perfect, making the stretching operation inconvenient and the observation of the stretching distance difficult, hindering precise control and making it difficult to meet the production needs of PTFE films with different specifications and performance requirements.

[0003] Therefore, we designed a polytetrafluoroethylene film longitudinal stretching machine to meet the needs of practical applications. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a polytetrafluoroethylene film longitudinal stretching machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a polytetrafluoroethylene film longitudinal stretching machine, including a base, a vertical plate on the base, a fixing mechanism and a stretching mechanism on the vertical plate, the fixing mechanism including a receiving roller, the receiving roller being rotatably connected to the inner wall of the vertical plate, a first mounting frame fixedly installed on the vertical plate, a first cylinder fixedly installed at the top of the first mounting frame, the piston rod end of the first cylinder passing through the first mounting frame and fixedly installed with a pressure plate; The stretching mechanism includes a second mounting frame, which is fixedly mounted on a vertical plate. A second cylinder is fixedly mounted on the top end of the second mounting frame. The piston rod end of the second cylinder passes through the second mounting frame and is fixedly mounted on a mounting base. An extrusion roller is rotatably connected to the inner wall of the mounting base.

[0006] In detail, the vertical plates are set vertically, there are two vertical plates, and there are two receiving rollers.

[0007] In detail, there are two first mounting brackets, both of which are arched in shape. There are two first cylinders, which are vertically arranged, and the pressure plate is horizontally arranged.

[0008] In detail, a limiting rod is fixedly installed on the pressure plate. The limiting rod is vertically arranged and passes through the top of the first mounting frame.

[0009] In detail, the second mounting bracket is L-shaped, the second cylinder is vertically arranged, and the extrusion roller is horizontally arranged.

[0010] In detail, a limiting groove is provided on the vertical plate. The limiting groove is a square through groove. Limiting blocks are fixedly installed on both sides of the mounting base. The limiting blocks are square blocks and slide on the inner wall of the limiting groove.

[0011] In detail, a pointer is fixedly installed on the side of the limiting block, and a scale is fixedly installed on the base, with the scale set vertically.

[0012] Core function: When the polytetrafluoroethylene (PTFE) film needs to be stretched, the PTFE is passed between the left pressure plate and the receiving roller, then through the bottom of the extrusion roller, and finally through the gap between the right pressure plate and the receiving roller. After passing through, the first cylinders on both sides are activated. The first cylinders will drive the pressure plate to move. When the pressure plate moves, it will move vertically due to the limiting action of the limiting rod until the pressure plate fixes the PTFE film to the receiving roller. After the polytetrafluoroethylene film is fixed, the second cylinder is started. The second cylinder drives the mounting base to move. Under the limiting action of the limiting block and the limiting slide, the mounting base will move vertically. When the mounting base moves vertically, it will drive the extrusion roller to move vertically until the extrusion roller moves vertically and stretches the polytetrafluoroethylene film.

[0013] Furthermore, when the mounting base moves vertically, the pointer will move vertically via the limit block. Combined with the scale, this makes it easy to observe the distance at one end of the extrusion roller, which is beneficial for controlling the stretching length.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application: 1. The fixed mechanism facilitates the fixation of both ends of the polytetrafluoroethylene film, thereby making it easier to stretch the polytetrafluoroethylene film longitudinally. 2. The addition of a stretching mechanism facilitates longitudinal stretching of the polytetrafluoroethylene film, and the stretching distance is easy to observe. Attached Figure Description

The fixing mechanism facilitates fixing both ends of the PTFE film, thereby facilitating longitudinal stretching of the PTFE film. The stretching mechanism facilitates longitudinal stretching of the PTFE film, and the stretching distance is easy to observe. The fixing mechanism includes a receiving roller 23, which is rotatably connected to the inner wall of the vertical plate 4. A first mounting frame 21 is fixedly installed on the vertical plate 4.

The piston rod end of the second cylinder 31 passes through the second mounting bracket 36 and is fixedly mounted on a mounting base 38. An extrusion roller 37 is rotatably connected to the inner wall of the mounting base 38.

[0019] It should be further noted that the vertical plates 4 are set vertically, and there are two vertical plates 4, and there are two receiving rollers 23.

After passing through, the first cylinders 24 on both sides are activated. The first cylinders 24 will drive the pressure plate 22 to move. When the pressure plate 22 moves, it will move vertically due to the limiting action of the limiting rod 25 until the pressure plate 22 fixes the polytetrafluoroethylene film onto the receiving roller 23. After the polytetrafluoroethylene film is fixed, the second cylinder 31 is started. The second cylinder 31 drives the mounting base 38 to move. Under the limiting action of the limiting block 33 and the limiting slide 35, the mounting base 38 will move vertically.
