[0003] Although the above solution has the above advantages, the disadvantage of the above solution is that the traditional cutting mechanism cannot cut the polytetrafluoroethylene film better, the structure is complex, it is not convenient for manual operation, the cutting speed is slow, and the cutting efficiency of the cutting mechanism is reduced. In addition, when the polytetrafluoroethylene film is transported, it is not convenient to flexibly clamp it, causing it to deviate from the direction during transportation and need to be re-placed, which is very troublesome and reduces the practicality of the cutting mechanism.

It can also flexibly clamp the polytetrafluoroethylene film when conveying it to prevent it from deviating from the direction during conveyance, without the need for repositioning, which is very simple and improves the practicality of the cutting mechanism.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a polytetrafluoroethylene film cutting mechanism, which comprises:

[0006] base plate;

[0007] Two connecting plates are provided on both sides of the outer surface of the bottom plate, and the top centers of the two connecting plates are connected to a cylinder;

[0008] A slider is movably sleeved on the outer surface of the cylinder, and a crossbar is connected to one side of the outer surface of the slider;

[0009] A heightening block is arranged at the bottom center of the base plate, and a dual-axis motor is fixedly installed at the bottom center of the heightening block;

[0010] Two discs are respectively arranged on the output ends of both sides of the dual-axis motor;

[0011] A cross bar is movably connected to one side of the disc.

[0012] As a further improvement of the present application: the outer surface of the cross bar is movably sleeved inside the cross bar, and the top end of the cylinder is connected to a limiting plate for facilitating positioning.

[0013] As a further improvement of the present application: a flat plate is connected to one side of the two sliders, and a blade is connected to the bottom of the flat plate. When the sliders move, the blades are driven to move horizontally downward and cut the polytetrafluoroethylene film.

[0014] As a further improvement of the present application: a placement block is connected to the top of the base plate near the edge, and support legs are connected to the four corners of the bottom of the base plate for easy support.

[0015] As a further improvement scheme of the present application: two square plates are connected to the top of the base plate near the edge, the bottom of the two square plates are connected to two springs, and the bottom of the two square plates are connected to telescopic columns, which limit the pop-up direction of the springs.

[0016] As a further improvement of the present application: the bottom ends of the two springs are connected with a splint, the top of the splint is connected to the bottom ends of the two telescopic columns near the edge, and the upper roller and the splint as a whole are tightly attached to the surface of the polytetrafluoroethylene film under the influence of the elastic force of the spring.

[0017] As a further improvement of the present application: upper rollers are movably connected to both sides of the inner wall of the splint, and manual transmission is assisted by the upper rollers and the lower rollers.

[0018] As a further improvement of the present application: two lower rollers are fixedly embedded inside the bottom plate to facilitate flexible clamping.

[0019] Compared with the prior art, the advantages and positive effects of this application are:

[0020] 1. In this application, the polytetrafluoroethylene film cylinder is first placed horizontally in the placement block and installed. Then the polytetrafluoroethylene film to be cut is pulled out, passed between the two upper rollers and the lower roller, and the polytetrafluoroethylene film is stretched to the required length. At this time, the staff turns on the external power supply of the dual-axis motor and uses the controller to start the dual-axis motor. The output ends on both sides of the dual-axis motor begin to drive the disc to rotate forward respectively. As the disc continues to rotate, the cross bar begins to pull the slider downward as a whole. At the same time, the movement of the slider drives the blade to move horizontally downward and cut the polytetrafluoroethylene film extremely quickly, thereby achieving better cutting of the polytetrafluoroethylene film. The structure is simple, easy to operate manually, and the cutting speed is fast, which improves the cutting efficiency of the cutting mechanism.

[0021] 2. In the present application, when the polytetrafluoroethylene film is inserted between the two upper rollers and the lower roller, the upper roller and the clamping plate as a whole are affected by the elastic force of the spring and are tightly attached to the surface of the polytetrafluoroethylene film. The telescopic column limits the spring-out direction of the spring, thereby flexibly clamping the polytetrafluoroethylene film to prevent it from deviating from the direction, and manually conveying it with the assistance of the upper roller and the lower roller, so that the polytetrafluoroethylene film can be flexibly clamped when being conveyed to prevent it from deviating from the direction during conveyance. There is no need to reposition it, which is very simple and improves the practicality of the cutting mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways than those described herein. Therefore, the present application is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1 to 4 As shown, the present application provides a polytetrafluoroethylene film cutting mechanism, which includes:

[0030] Base plate 1;

[0031] Two connecting plates 107 are provided on both sides of the outer surface of the bottom plate 1, and a cylinder 109 is connected to the top center of the two connecting plates 107;

[0032] The slider 106 is movably mounted on the outer surface of the cylinder 109, and one side of the outer surface of the slider 106 is connected to the crossbar 105;

[0033] The heightening block 102 is arranged at the bottom center of the base plate 1, and a dual-axis motor 103 is fixedly installed at the bottom center of the heightening block 102;

[0034] Two discs 104 are respectively provided on the output ends of the dual-axis motor 103 on both sides;

[0035] The crossbar 105 is movably connected to one side of the disc 104 .

[0036] like Figures 1 to 4 As shown, the outer surface of the crossbar 105 is movably sleeved inside the crossbar 105, and the top end of the cylinder 109 is connected to the limiting plate 108 for easy positioning.

[0037] like Figures 1 to 4 As shown, a plate 110 is connected to one side of the two sliders 106 , and a blade 111 is connected to the bottom of the plate 110 . When the sliders 106 move, the blade 111 is driven to move horizontally downward and cut the polytetrafluoroethylene film.

[0038] like Figures 1 to 4 As shown, a placement block 112 is connected to the top of the base plate 1 near the edge, and support legs 101 are connected to the four corners of the bottom of the base plate 1 for easy support.

[0039] like Figures 1 to 4 As shown, two square plates 2 are connected to the top of the base plate 1 near the edge, and two springs 202 are connected to the bottom of the two square plates 2. The bottom of the two square plates 2 is connected to a telescopic column 201, which limits the pop-up direction of the spring 202.

[0040] like Figures 1 to 4 As shown, the bottom ends of the two springs 202 are connected to a splint 203, and the top of the splint 203 is connected to the bottom ends of the two telescopic columns 201 near the edge. The upper roller 204 and the splint 203 as a whole are tightly attached to the surface of the polytetrafluoroethylene film under the influence of the elastic force of the spring 202.

[0041] like Figures 1 to 4 As shown, upper rollers 204 are movably connected to both sides of the inner wall of the clamping plate 203, and the upper rollers 204 and the lower rollers 205 assist manual transmission.

[0042] like Figures 1 to 4As shown, two lower rollers 205 are fixedly embedded inside the bottom plate 1 to facilitate flexible clamping.

[0043] When in use, first place the polytetrafluoroethylene film cylinder horizontally in the placement block 112 and install it. Then, pull out the polytetrafluoroethylene film to be cut, pass it between the two upper rollers 204 and the lower roller 205, and stretch the polytetrafluoroethylene film to the required length. At this time, the staff turns on the external power supply of the dual-axis motor 103 and uses the controller to start the dual-axis motor 103. The output ends on both sides of the dual-axis motor 103 begin to drive the disc 104 to rotate forward respectively. As the disc 104 continues to rotate, the cross bar 105 begins to pull the slider 106 downward as a whole. While the slider 106 moves, it drives the blade 111 to start moving horizontally downward and cut the polytetrafluoroethylene film extremely quickly, thereby achieving better results in the polytetrafluoroethylene film. The polytetrafluoroethylene film can be cut with a simple structure, convenient manual operation, and fast cutting speed, thereby improving the cutting efficiency of the cutting mechanism. When the polytetrafluoroethylene film is inserted between the two upper rollers 204 and the lower roller 205, the upper roller 204 and the clamping plate 203 are affected by the elastic force of the spring 202 and are tightly attached to the surface of the polytetrafluoroethylene film. The telescopic column 201 limits the pop-up direction of the spring 202, thereby flexibly clamping the polytetrafluoroethylene film to prevent it from deviating from the direction, and the upper roller 204 and the lower roller 205 assist manual transmission, so that the polytetrafluoroethylene film can be flexibly clamped when being transmitted to prevent it from deviating from the direction during transmission, without the need for repositioning, which is very simple and improves the practicality of the cutting mechanism.
