Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene microporous films, and in particular to a polytetrafluoroethylene microporous film calendering machine. Background Technology

[0002] An existing patent (publication number: CN113878780A) discloses a polytetrafluoroethylene (PTFE) microporous film calendering machine. It includes a machine body, on which a first pressure roller and a second pressure roller are mounted. The machine body also has a drive mechanism for driving the first and second pressure rollers to rotate in opposite directions, a thickness gauge for measuring the thickness of the PTFE film, and an adjustment mechanism for driving the first and second pressure rollers to move in opposite directions. The thickness gauge is electrically connected to the adjustment mechanism. However, this device, which includes a "receiving device comprising a second frame and a receiving roller," relies on the receiving roller at the rear of the machine body to collect the PTFE microporous film. If the receiving roller needs to be replaced after winding during the winding process, it may not be able to temporarily fix and cut the PTFE microporous film, thus having certain limitations. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a PTFE microporous film calender that calenders a PTFE microporous film using a calendering bottom and top roller inside a calendering table, and then winds it up using a winding roller at the rear of the equipment platform. If the winding roller is fully wound and needs to be replaced midway, a clamping cylinder at the front of the clamping frame raises the lower clamp, temporarily clamping the PTFE microporous film with the upper and lower clamps. Then, a cutting cylinder at the top of the cutting frame raises and lowers the cutting blade, cutting the PTFE microporous film. This allows the equipment to replace a fully wound winding roller midway and, with the assistance of two sets of upper and lower clamps, temporarily clamps the PTFE microporous film at both ends, preventing it from scattering at the cut. This increases the adaptability of the PTFE microporous film calender.

[0004] The objective of this utility model is achieved through the following technical solution:

[0008] 1. In the operation of this utility model PTFE microporous film calender, the PTFE microporous film is calendered by the calendering bottom roller and calendering top roller inside the calendering table, and then wound up by the winding roller at the rear of the equipment platform. If the winding roller is fully wound and needs to be replaced midway, the clamping cylinder at the front of the clamping frame drives the lower clamp to rise, so that the upper and lower clamps temporarily hold the PTFE microporous film. Then, the cutting cylinder at the top of the cutting frame drives the cutter to rise and fall, so that the cutter cuts the PTFE microporous film. This allows the equipment to replace the fully wound winding roller midway, and with the help of two sets of upper and lower clamps, the PTFE microporous film at both ends is temporarily held to prevent it from scattering at the cut, thereby increasing the adaptability of the equipment.

[0009] 2. During the use of the polytetrafluoroethylene microporous film calender of this utility model, by removing the bolts on the side of the chuck, the chuck can be disengaged from the winding shaft, and the winding wheel on the side of the winding shaft can be pulled out, so that the winding wheel can be quickly replaced, thereby increasing the working efficiency of the equipment.

[0010] 3. During the use of this utility model PTFE microporous film calender, after the PTFE microporous film is cut and clamped by the upper and lower clamps, the transmission belt motor on the side of the platform cavity drives the transmission belt main wheel to rotate. At the same time, the transmission belt main wheel moves the transmission belt and simultaneously moves the two sets of upper and lower clamps out of the cutter's range. This makes it easier for workers to operate the PTFE microporous film inside the upper and lower clamps, avoiding the risk of their arms entering the cutter and causing scratches, thereby increasing the safety of the equipment.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0024] Example 1:

[0025] A polytetrafluoroethylene (PTFE) microporous film calender includes an equipment platform 01, a calendering table 02, a cutter holder 14, a cutter 15, a drive belt main pulley 18, a drive belt motor 19, a clamp cylinder 25, and a clamp positioning rod 30.

The cutter holder 14 is fixedly connected to the cutter 15 by bolts. The upper part of the equipment platform 01 is fixedly connected to the cutting table 37. The cutter 15 is positioned corresponding to the upper part of the cutting table 37. The lower part of the equipment platform 01 has a platform cavity 16.

[0029] The output shaft of the drive belt motor 19 of this utility model is fixedly connected to the main drive belt pulley 18, and the auxiliary drive belt pulley 17 is connected to the main drive belt pulley 18 via a drive belt. During the use of the PTFE microporous film calender, after the PTFE microporous film is cut and clamped by the upper clamp 27 and lower clamp 28, the drive belt motor 19 on the side of the platform cavity 16 drives the main drive belt pulley 18 to rotate. This causes the main drive belt pulley 18 to move the drive belt, and simultaneously, the drive belt causes the two sets of upper clamps 27 and lower clamps 28 to disengage from the cutter 15, facilitating the operator's handling of the cutter. The upper clamp 27 and the lower clamp 28 operate through the polytetrafluoroethylene microporous membrane inside, preventing the arm from entering the cutter 15 and causing scratches, thereby increasing the safety of the equipment.

Then, the film is cut by the upper part of the cutter frame 10. The blade cylinder 13 drives the cutter 15 to rise and fall, so that the cutter 15 cuts the polytetrafluoroethylene microporous film, thereby allowing the equipment to change the winding reel 35 midway through the process. It also works with two sets of upper clamps 27 and lower clamps 28 to temporarily clamp the polytetrafluoroethylene microporous film at both ends to prevent it from scattering at the cut, thus increasing the adaptability of the equipment. The upper part of the clamp cylinder 25 is fixedly connected to the lower clamp 28. The front part of the lower clamp 28 has a clamp guide cylinder 29.
