[0002] Polytetrafluoroethylene is a high-performance engineering plastic widely used in chemical, electronic, electrical and other industries because of its excellent high temperature resistance, corrosion resistance and low friction coefficient. Polytetrafluoroethylene tube extrusion and sintering equipment is an industrial equipment specially used for the production of polytetrafluoroethylene tubes. It usually includes an extruder and corresponding auxiliary equipment. The extruder is the core component, which is used to heat, plasticize and extrude the polytetrafluoroethylene material. During the extrusion process of polytetrafluoroethylene tubes, when the extruded pipe is not in line with the height of other equipment (such as cooling troughs, tractors, etc.), it is usually necessary to manually connect the extruded pipe with other equipment, but manual operation can easily lead to inaccurate alignment of the pipe with the cooling trough or other equipment, which will not only cause the pipe to be misaligned, bent or twisted. It is also easy to cause irregular shapes or dimensional deviations in the product, thus affecting the quality of the final product. Utility Model Content

[0024] Example

[0025] like Figure 1-4 As shown, the polytetrafluoroethylene tube extrusion and sintering equipment proposed by the utility model includes an extruder 1 and a pipe outlet 11 for extruding the pipe, and also includes: a right-angle bracket 2 installed on one end of the extruder 1, and a support mechanism rotatably connected to the right-angle bracket 2 to guide the pipe extruded from the pipe outlet 11 to a specified height; a fixing mechanism is arranged on the supporting mechanism to clamp the right-angle bracket 2 and limit the supporting mechanism to be stuck in a specified position.

[0026] Further, the supporting mechanism includes a main sleeve frame 3 rotatably connected to the top of the right-angle bracket 2, a receiving groove 34 is provided at one end of the main sleeve frame 3 close to the spiral rod 36, and a convex plate 52 is fixedly connected at one end of the secondary sleeve frame 5 away from the main sleeve frame 3, and the function of the convex plate 52 is to facilitate the secondary sleeve frame 5 to borrow force when sliding from the main sleeve frame 3. The secondary sleeve frame 5 is slidably sleeved on one end of the main sleeve frame 3 away from the right-angle bracket 2, a first arc groove 37 supporting the sliding of the pipeline is provided on the main sleeve frame 3, a second arc groove 53 supporting the sliding of the pipeline is provided on the secondary sleeve frame 5, and a rotating mechanism for limiting the sliding of the secondary sleeve frame 5 in the main sleeve frame 3 is provided at one end of the main sleeve frame 3 away from the right-angle bracket 2.

[0027] The rotating mechanism includes a screw rod 36 screwed to one end of the main sleeve 3. The function of the screw rod 36 is to restrict the secondary sleeve 5 after it slides out of the specified position from the main sleeve 3, so as to prevent the secondary sleeve 5 from retracting into the main sleeve 3, causing the secondary sleeve 5 to be unable to reach the height of other equipment. One end of the screw rod 36 is used to resist one end of the secondary sleeve 5 in the main sleeve 3, and the other end of the screw rod 36 is fixedly connected to the rotating handle 35.

[0028] Secondly, the fixing mechanism includes a pair of rotating rods 31 rotatably connected to the main sleeve 3, a clamping rod 32 is fixedly connected to the middle of one end of the rotating rod 31 close to the right-angle bracket 2, and a plurality of clamping blocks 4 arranged linearly are fixedly connected to the outer wall of the right-angle bracket 2. The material of the clamping block 4 is rubber, and the function is to allow the clamping rod 32 to be clamped into the clamping slot 41, while the anti-slip protrusion 42 can prevent the clamping rod 32 from being easily dislodged. The clamping block 4 is provided with a clamping slot 41 for clamping the clamping rod 32, and the inner wall of the clamping slot 41 is provided with an anti-slip protrusion 42 for preventing the clamping rod 32 from automatically dislodging from the clamping slot 41. The function of the anti-slip protrusion 42 is to prevent the clamping rod 32 from easily dislodging from the clamping slot 41.

[0029] Furthermore, a first protrusion 33 is provided inside one end of the main sleeve 3 close to the secondary sleeve 5, and a second protrusion 51 is provided at one end of the secondary sleeve 5 inserted into the main sleeve 3 to clamp the first protrusion 33 and limit the secondary sleeve 5 from escaping from the main sleeve 3. The second protrusion 51 and the first protrusion 33 are clamped with each other to prevent the secondary sleeve 5 from escaping from the main sleeve 3.

[0030] In this embodiment, when it is necessary to use a polytetrafluoroethylene tube extrusion sintering device, such as Figure 1As shown, the main sleeve 3 is rotated upward or downward with the top of the right-angle bracket 2 as the center, and then the secondary sleeve 5 is made to slide along the main sleeve 3 toward other equipment, and then the end of the secondary sleeve 5 away from the main sleeve 3 is slid to the same height as the equipment. At this time, the rotating handle 35 can be rotated to drive the spiral rod 36 to rotate. Since the spiral rod 36 is spirally connected to the main sleeve 3, the end of the spiral rod 36 away from the rotating handle 35 will resist the secondary sleeve 5, so that the secondary sleeve 5 cannot slide in the main sleeve 3. Then, the pair of rotating rods 31 are rotated to drive the clamping rod 32 to rotate, so that the clamping rod 32 rotates and is clamped into the clamping groove 41 in the clamping block 4, and at the same time, the end of the secondary sleeve 5 away from the main sleeve 3 is made to be consistent with the height of the equipment. Finally, when the pipe extruded from the outlet 11 first slides along the first arc groove 37 and then along the second arc groove 53 to connect with the equipment at a specified height, it is simple and easy to operate.
