Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a polytetrafluoroethylene (PTFE) plate welding equipment. Background Technology

[0002] Utility model patent CN214820965U discloses an automatic heating and welding device for polytetrafluoroethylene (PTFE) strips. Addressing the problem of fixing the position of PTFE strips on a heating block, the following solution is proposed: The device includes a heating block, with sliding frames fixedly installed on its top, bottom, left, and right sides. Clamps are slidably connected to the inner sides of each of the four sliding frames. Return springs are fixedly installed on the clamps and are also fixedly mounted on the heating block. A support plate is fixedly installed on the top of the heating block, and two symmetrically arranged pulleys are rotatably connected to the front side of the support plate. This utility model utilizes a method where the clamps at the top of the heating block are pushed, and the clamps, through a winch and pulleys, tighten the other three clamps, bringing the four clamps closer together to hold the PTFE strip. Once clamped, the device can automatically position itself.

[0003] However, the device has certain shortcomings in use. When welding polytetrafluoroethylene (PTFE) sheets, it cannot ensure close contact between the two sheets, which affects the welding quality. At the same time, the device is not convenient for clamping and fixing sheets of different thicknesses. Utility Model Content

[0004] The purpose of this invention is to provide a polytetrafluoroethylene (PTFE) plate welding device that solves the problem that when welding PTFE plates, the two plates cannot be made in close contact, which affects the welding quality. At the same time, the device is not convenient for clamping and fixing plates of different thicknesses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polytetrafluoroethylene (PTFE) plate welding device, comprising a base plate, an adjustment mechanism provided on the base plate, a sliding plate provided on the adjustment mechanism, a sliding strip fixedly connected to the lower end of the sliding plate, the sliding strip being slidably connected to the base plate, and a bracket fixedly connected to the upper end of the sliding plate, the bracket being provided with a limit mechanism.

[0006] Preferably, the adjusting mechanism includes a motor. The motor is fixedly mounted on the surface of the base plate. The motor's shaft passes through the base plate and is rotatably connected to it. A bidirectional screw is fixedly connected to the end of the motor's shaft. The bidirectional screw is rotatably connected to the base plate. A slide block is movably connected to the outer side of the bidirectional screw. A top plate is threadedly connected to the outer side of the bidirectional screw. The top plate and the base plate are slidably connected. A spring is provided on the outer side of the bidirectional screw. The motor drives the bidirectional screw to rotate and the top plate to perform threaded movement, which in turn causes the spring to elastically compress the slide block. This causes the slide block to move the polytetrafluoroethylene (PTFE) plate placed on it, keeping the two PTFE plates in contact and preventing gaps during welding.

[0007] Preferably, the slide block and the base plate are slidably connected, and the slide block and the slide plate are fixedly connected. The movement of the slide plate is controlled by setting the slide block.

[0008] Preferably, one end of the spring is fixedly connected to the top plate, and the other end of the spring is fixedly connected to the slide block. By setting the spring, the slide block is elastically compressed.

[0009] Preferably, the limiting mechanism includes a lead screw, which is mounted inside the bracket via a bearing. A screw cylinder is threadedly connected to the outside of the lead screw, and a slide cylinder is slidably connected to the outside of the screw cylinder. A sliding pin is fixedly connected to the outside of the screw cylinder, and the sliding pin and slide cylinder are slidably connected. A limiting plate is fixedly connected to the lower end of the slide cylinder, and a compression spring is provided inside the slide cylinder. By rotating the lead screw and screw cylinder to perform threaded movement, the compression spring elastically compresses the limiting plate, causing the limiting plate to elastically press the PTFE sheet onto the sliding plate, thus preventing the PTFE sheet from moving during the welding process.

[0010] Preferably, one end of the compression spring is fixedly connected to the screw cylinder, and the other end of the compression spring is fixedly connected to the limiting plate. By setting the compression spring, the limiting plate is elastically compressed.

[0011] Preferably, a conduit is fixedly connected to the upper end of the limiting plate, and a guide rod is slidably connected inside the conduit. The guide rod and the bracket are fixedly connected. By setting the conduit and the guide rod in cooperation, the movement of the limiting plate is guided.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a bidirectional screw to rotate and a top plate to make a threaded movement, which in turn causes a spring to elastically compress a slide block, thereby causing the slide block to move the polytetrafluoroethylene (PTFE) plate placed on it, so that the two PTFE plates maintain contact and avoid gaps during the welding process.

[0014] 2. This utility model uses the rotation of the lead screw and the screw barrel to make a threaded movement, which in turn causes the compression spring to elastically squeeze the limiting plate, so that the limiting plate elastically squeezes the polytetrafluoroethylene plate onto the sliding plate, thus preventing the polytetrafluoroethylene plate from moving during the welding process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 3 A polytetrafluoroethylene (PTFE) sheet welding equipment includes a base plate 1, an adjustment mechanism 2 on the base plate 1, a slide plate 3 on the adjustment mechanism 2, a slide bar 4 fixedly connected to the lower end of the slide plate 3, the slide bar 4 and the base plate 1 being slidably connected, and a bracket 5 fixedly connected to the upper end of the slide plate 3, with a limit mechanism 6 on the bracket 5.

[0022] Please see Figures 1-2The adjusting mechanism 2 includes a motor 21. The motor 21 is fixedly mounted on the surface of the base plate 1. The rotating shaft of the motor 21 passes through the base plate 1 and is rotatably connected to the base plate 1. A bidirectional screw 22 is fixedly connected to the end of the rotating shaft of the motor 21. The bidirectional screw 22 is rotatably connected to the base plate 1. A slide block 23 is movably connected to the outer side of the bidirectional screw 22. The slide block 23 is slidably connected to the base plate 1. The slide block 23 is fixedly connected to the slide plate 3. The movement of the slide plate 3 is controlled by setting the slide block 23. A top plate 24 is threadedly connected to the outer side of the bidirectional screw 22. The top plate 24 and... The base plate 1 is slidably connected, and a spring 25 is provided on the outside of the bidirectional screw 22. One end of the spring 25 is fixedly connected to the top plate 24, and the other end of the spring 25 is fixedly connected to the slide block 23. By setting the spring 25, the slide block 23 is elastically compressed. The motor 21 drives the bidirectional screw 22 to rotate and the top plate 24 to make threaded movements, thereby causing the spring 25 to elastically compress the slide block 23, which in turn causes the slide plate 3 to move the polytetrafluoroethylene plate placed on it, so that the two polytetrafluoroethylene plates maintain contact and avoid gaps during the welding process.

[0023] Please see Figure 1 , Figure 3 , Figure 4 The limiting mechanism 6 includes a lead screw 61. The lead screw 61 is mounted inside the bracket 5 via bearings. A screw cylinder 62 is threadedly connected to the outside of the lead screw 61. A slide cylinder 63 is slidably connected to the outside of the screw cylinder 62. A sliding pin 64 is fixedly connected to the outside of the screw cylinder 62. The sliding pin 64 and the slide cylinder 63 are slidably connected. A limiting plate 65 is fixedly connected to the lower end of the slide cylinder 63. A compression spring 66 is installed inside the slide cylinder 63. One end of the compression spring 66 is fixedly connected to the screw cylinder 62, and the other end of the compression spring 66 is fixedly connected to the limiting plate 65. A compression spring 66 causes the limiting plate 65 to be elastically compressed. A conduit 67 is fixedly connected to the upper end of the limiting plate 65. A guide rod 68 is slidably connected inside the conduit 67. The guide rod 68 is fixedly connected to the bracket 5. By setting the conduit 67 and the guide rod 68 to cooperate, the movement of the limiting plate 65 is guided. By rotating the lead screw 61 and the screw cylinder 62 to make threaded movement, the compression spring 66 elastically compresses the limiting plate 65, so that the limiting plate 65 elastically compresses the polytetrafluoroethylene plate onto the sliding plate 3, preventing the polytetrafluoroethylene plate from moving during the welding process.

[0024] The specific implementation process of this utility model is as follows: In use, the polytetrafluoroethylene (PTFE) plate is placed on the slide plate 3, and then the lead screw 61 is manually rotated. The rotation of the lead screw 61 and the screw barrel 62 make a threaded movement, which causes the screw barrel 62 to move downward. The movement of the screw barrel 62 compresses the compression spring 66, which causes the compression spring 66 to elastically compress the limiting plate 65, so that the limiting plate 65 and the PTFE plate come into contact. The limiting plate 65 elastically compresses the PTFE plate on the slide plate 3, preventing the PTFE plate from moving during the welding process. Then, the motor 21 is started, and the motor 21 drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 and the top plate 24 make a threaded movement, which causes the spring 25 to elastically compress the slide block 23, which in turn causes the slide plate 3 to move the PTFE plate placed on it, so that the two PTFE plates keep in contact and avoid gaps during the welding process.
