[0002] Teflon coating is a process that applies a polytetrafluoroethylene coating to the surface of pipes. Its main purpose is to improve the corrosion resistance, high temperature resistance and non-stick properties of the pipes.

[0003] In existing technologies, operators typically use spray guns to spray the outer or inner walls of pipes. However, due to the excessive length of the pipes and their curved surfaces, it is inconvenient to stably position the pipes during the spraying process, and uneven spraying can occur. To address these issues, a Teflon spraying device is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: it is inconvenient to stably position the pipe during the spraying process, and uneven spraying may occur during the spraying process.

The pressing block is generally frustum-shaped, and the side of the pressing block is slidably connected along the inner wall of the insert rod.

[0009] The outer surface of the insert rod is slidably connected with abutment blocks around it. Each abutment block is evenly arranged around the lead rod. Each abutment block is set as an inclined surface on the side closest to the lead rod, and the lead rod abuts against the surface of the extrusion block at the inclined surface.

[0010] The stop block is fixedly connected to a spring near the lead screw, and the other end of the spring is fixedly connected to the inner wall of the insertion rod. The stop block is fixedly connected to a washer at the end away from the spring.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5 As shown, a Teflon coating device includes an adjusting mechanism 1, a pressing mechanism 2 is provided on the side of the adjusting mechanism 1, the adjusting mechanism 1 includes an electric cylinder 103 and a motor 105; it also includes: the pressing mechanism 2 includes an insert rod 201, a lead screw 205 is rotatably connected to the middle of one side of the inner wall of the insert rod 201, and an extrusion block 206 is threaded on the outer wall of the lead screw 205. The extrusion block 206 is generally frustoconical in shape, and the side of the extrusion block 206 is slidably connected along the inner wall of the insert rod 201. The outer surface of the insertion rod 201 is slidably connected with abutment blocks 208 around its perimeter. These abutment blocks 208 are evenly arranged around the lead screw 205, with each abutment block 208 having an inclined surface on the side closest to the lead screw 205. The lead screw 205 abuts against the surface of the pressing block 206 at the inclined surface. A spring 207 is also fixedly connected to each abutment block 208 near the lead screw 205. The other end of the spring 207 is fixedly connected to the inner wall of the insertion rod 201. A washer 209 is fixedly connected to the end of the abutment block 208 furthest from the spring 207. Figures 2-3 As shown, the spring 207 pulls the stop block 208 to retract into the insertion rod 201, thereby preventing the stop block 208 from protruding and hindering the pipe from being sleeved on the outside of the insertion rod 201;

[0029] A push groove 202 is formed on the inner wall of the insertion rod 201 on the side away from the lead screw 205. A movable cavity 203 is formed on the inner wall of the insertion rod 201 between the push groove 202 and the lead screw 205. A second rotating sleeve 204 is fixedly connected to one end of the lead screw 205. One side of the second rotating sleeve 204 extends into the movable cavity 203, and a regular hexagonal hole is formed in the middle of the inner wall of the second rotating sleeve 204. Figures 2-3 As shown, the connecting block 108 on the right is inserted into the middle of the inner wall of the second rotating sleeve 204. When the connecting block 108 rotates, it drives the second rotating sleeve 204 to rotate.

[0030] The adjusting mechanism 1 includes a base plate 101, with sliding seats 102 slidably connected to both sides of the top of the base plate 101. The top of the sliding seats 102 is also fixedly installed with a motor 105. The output shaft of the motor 105 is fixedly connected to a first rotating sleeve 106. A regular hexagonal hole is formed in the inner wall of the middle part of the first rotating sleeve 106. Figures 1-3 As shown, by adjusting the distance between the two sliding seats 102, it is convenient to clamp pipes of different lengths;

[0031] The adjusting mechanism 1 also includes a telescopic rod 107, with connecting blocks 108 fixedly connected to both ends of the telescopic rod 107. The connecting blocks 108 are hexagonal in shape from a side view. One side of the connecting block 108 is slidably connected to the inner wall of the middle portion of the first rotating sleeve 106, and the other side of the connecting block 108 is slidably connected to the inner wall of the middle portion of the second rotating sleeve 204. Figures 2-3 As shown, two connecting blocks 108 are inserted into the first rotating sleeve 106 and the second rotating sleeve 204 respectively, so that the first rotating sleeve 106 and the second rotating sleeve 204 rotate synchronously.

[0032] The middle part of the telescopic rod 107 is inserted into the inner wall of the insert rod 201, and push blocks 109 are fixedly connected to all four sides of the middle surface of the telescopic rod 107. The outer wall of the push block 109 abuts against the inner side of the push groove 202. Figure 5 As shown, after the push block 109 moves into the inner wall of the push groove 202, the telescopic rod 107 rotates and drives the insertion rod 201 outside the push groove 202 to rotate through the push block 109;

[0033] The sliding seat 102 is fixedly installed on its top surface, below the motor 105, and to the electric cylinder 103. A clamping sleeve 104 is fixedly connected to the extension end of the electric cylinder 103. The inner wall of the clamping sleeve 104 is rotatably connected to the telescopic rod 107. Figures 1-3 As shown, the control cylinder 103 controls the clamping sleeve 104 to move in the horizontal direction, and then the clamping sleeve 104 drives the telescopic rod 107 to move on the inner wall of the insertion rod 201.

[0034] The working principle of this utility model:

[0035] When the device is in use, the pipe is sleeved on the outside of the insertion rod 201 and pressed against the outer surface of the insertion rod 201. Then, the motor 105 is started to drive the first rotating sleeve 106 to rotate, thereby rotating the telescopic rod 107 and the connecting blocks 108 at both ends. One side connecting block 108 pushes the regular hexagonal groove in the second rotating sleeve 204, driving the lead screw 205 to rotate inside the insertion rod 201. The lead screw 205 pushes the pressing block 206 to move towards the abutment block 208, thereby pressing the bottom inclined surface of the abutment block 208 and pushing the abutment block 208 outward from the insertion rod 201. Then, the abutment block 208 presses against the inner wall of the pipe through the gasket 209, and the pipe is thus internally supported and fixed.

[0036] Secondly, the extension end of the electric cylinder 103 retracts, and the telescopic rod 107 moves toward the first rotating sleeve 106 through the clamping sleeve 104. The connecting block 108 separates from the second rotating sleeve 204, and the push block 109 enters the push groove 202. When the motor 105 is started again to drive the telescopic rod 107 to rotate, the push block 109 pushes the inner wall of the push groove 202 and drives the entire insertion rod 201 to rotate around the telescopic rod 107 above the sliding seat 102. Thus, the abutment block 208 and the gasket 209 drive the external pipe to rotate. At this time, the operator can hold the spray gun and aim it at the fixed point of the pipe, and spray the inner or outer wall of the pipe.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
