[0002] In order to make the flange anti-corrosion, a PTFE tube is usually lined inside the flange. When lining the flange with the PTFE tube, since the end face of the flange is a platform, it is necessary to first flange the two ends of the PTFE tube 90 degrees. The pipe mouth after flanged is fitted to the end face of the flange, and then the pipe mouth is melted and cooled by heat welding to achieve fixation with the end face of the flange.

[0003] For example, a Chinese patent (publication number: CN208513885U) discloses a polytetrafluoroethylene tube sheet thermal welding machine, comprising a heating plate, wherein the heating plate comprises an upper heating plate and a lower heating plate, wherein the upper heating plate is buckled on the lower heating plate, and further comprising a frame and a cylinder, wherein the frame is in an "L" shape, wherein the lower heating plate is arranged on the bottom side of the frame, wherein a connecting rod is arranged on the side of the upper heating plate, wherein a slide groove is provided on the side wall of the frame along its length direction, wherein the connecting rod passes through the slide groove and is connected to the piston rod of the cylinder, wherein the cylinder is detachably connected to the side wall of the frame, and the upper heating plate is linked by the cylinder, thereby replacing manual handling and reducing the labor load of the staff, and at the same time, the efficiency of cylinder handling is higher, thereby improving the working efficiency of the lined polytetrafluoroethylene tube.

[0004] However, the above search patent still has some shortcomings. Before welding, the polyfluoro tube has been assembled with the flange and is T-shaped.

When the polyfluoro tube is long, it cannot pass through the bottom of the upper heating plate. The operation is more troublesome and inconvenient to use. Therefore, a polyfluoro tube plate thermal welding machine is proposed to solve the above problems. Utility Model Content

[0026] See also Figure 2-3In this embodiment, the driving assembly includes a cylinder 501 fixed to the right side of the fixed bin 2 and the left end of the output shaft is fixed to the mobile bin 302. A support plate 502 is fixed to the top surface of the bottom plate 1. Two guide rods 503 are fixed to the right side of the support plate 502. A guide ring 504 whose outer peripheral wall is fixed to the mobile bin 302 is slidably connected on the outer peripheral wall of the guide rod 503. The right end of the guide rod 503 extends to the inside of the fixed bin 2 and is fixed to the right inner wall thereof. The two guide rods 503 are distributed front and back and are located at the front and back sides of the mobile bin 302. When it is necessary to control the welding mechanism for welding, the cylinder 501 is started, and the cylinder 501 drives the mobile bin 30 2 cooperates with the guide rod 503 and the guide ring 504 to slide rightward, so that the mobile bin 302 drives the mobile heating plate 304 to slide rightward, the top surface of the bottom plate 1 is rotatably connected with a screw rod 505, a gear 506 is fixed on the outer peripheral wall of the screw rod 505, a tooth plate 507 meshing with the gear 506 is fixed on the inner wall of the rear side of the mobile bin 302, a guide hole 508 is opened on the top surface of the lifting plate 303, an I-shaped block 509 is slidably connected in the guide hole 508, the screw rod 505 vertically penetrates the I-shaped block 509 and is threadedly connected thereto, the tooth plate 507 is located on the inner wall of the rear side of the mobile bin 302 and close to the lower right corner, and the length of the tooth plate 507 is the stroke length of the cylinder 501 The top surface of the I-shaped block 509 is provided with a threaded hole for the screw 505 to be threadedly connected, and the guide hole 508 is used for the I-shaped block 509 to slide left and right inside it.

When the cylinder 501 extends, the movable heating plate 304 will first move horizontally to the left to make the positioning column 305 disengage from the polyfluoro tube body 4, and then the movable heating plate 304 will move obliquely from the upper right side to the lower left side for storage, so as to facilitate the horizontal movement of the polyfluoro tube body 4 and take it out of the fixed heating plate 301.

[0027] The working principle of the above embodiment is:

[0028] (1) When in use, the polytetrafluoroethylene tube body 4 is inserted from the left side of the fixed heating plate 301, and the flange at its left end is in contact with the left side of the fixed heating plate 301. Then, the lifting plate 303 is controlled by the driving component to cooperate with the guide block 306 and the guide groove 307 to slide upward, and the movable heating plate 304 is driven to move upward and pass through the rectangular hole 308, so that the movable heating plate 304 and the fixed heating plate 301 are opposite to each other on the left and right. Further, the driving component controls the movable bin 302 to move rightward into the fixed bin 2, and then drives the movable heating plate 304 to move rightward and contact with the flange at the left end of the polytetrafluoroethylene tube body 4. At the same time, the positioning column 305 is inserted into the polytetrafluoroethylene tube body 4. At this time, the fixed heating plate 301 and the movable heating plate 304 can be heated and welded;

[0029] (2) When it is necessary to control the welding mechanism for welding, start the cylinder 501, and the cylinder 501 drives the mobile bin 302 to cooperate with the guide rod 503 and the guide ring 504 to slide to the right, so that the mobile bin 302 drives the mobile heating plate 304 to slide to the right, and at the same time, the mobile bin 302 drives the tooth plate 507 to move to the right, the tooth plate 507 drives the gear 506 to rotate, the gear 506 drives the screw 505 to rotate, and the screw 505 drives the I-shaped block 509 to move upward, thereby driving the lifting plate 303 to slide upward, so that the mobile heating plate 304 moves from the lower left side to the upper right side. When the cylinder 501 is retracted to half, at this time, the screw 505 raises the lifting plate 303 to the maximum The top portion makes the movable heating plate 304 and the fixed heating plate 301 opposite to each other on the left and right, and at the same time, the gear 506 disengages from the left side of the tooth plate 507, and the cylinder 501 continues to shrink. At this time, the movable warehouse 302 continues to drive the movable heating plate 304 to move right, but the screw 505 no longer rotates, so that the movable heating plate 304 moves horizontally to the right so that the positioning column 305 can be inserted. When the cylinder 501 extends, the movable heating plate 304 will first move horizontally to the left side to make the positioning column 305 disengage from the polytetrafluoroethylene tube body 4, and then the movable heating plate 304 will move obliquely from the upper right side to the lower left side for storage, so as to facilitate the horizontal movement of the polytetrafluoroethylene tube body 4 and take it out from the fixed heating plate 301.
