Description

Technical Field

[0001] This utility model relates to the technical field of pipe production equipment, specifically a conveying structure for polytetrafluoroethylene (PTFE) pipe production equipment. Background Technology

[0002] Polytetrafluoroethylene (PTFE) pipes are widely used in chemical, pharmaceutical and other fields due to their excellent corrosion resistance and high temperature resistance. In the production process, the conveying of the pipes after cooling and forming is a key step to ensure production continuity. The conveying mechanism needs to be flexibly adjusted according to different pipe models (diameters) to ensure stable conveying of the pipes without damage.

[0003] The existing PTFE pipe conveying equipment has certain limitations: the traction mechanism spacing adjustment and the guide limit mechanism adjustment are independent of each other. When changing pipes of different diameters, the traction machine and the limit mechanism need to be operated separately, which is cumbersome and has low adjustment efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a conveying structure for a polytetrafluoroethylene (PTFE) pipe production equipment to solve the technical problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying structure for a polytetrafluoroethylene (PTFE) pipe production equipment, comprising an installation cabinet, an adjustment assembly on the top of the installation cabinet, the adjustment assembly including an installation frame, a guide rod and a screw connected to the bottom of the installation frame, two slides externally connected to the guide rod and the screw, a traction machine body mounted on the outside of each of the two slides, a rack connected to the top of one of the slides via a connecting plate, a fixing assembly mounted on one side of the top of the installation cabinet, the fixing assembly including a fixing frame, a limit frame internally connected to the fixing frame, a clamping frame connected to one side of the fixing frame via a connecting rod, and a ball bearing connected to one end of the clamping frame, a limit rod internally connected to the limit frame, and a gear plate externally connected to the limit frame.

[0006] Furthermore, the main body of the traction machine is a tracked traction machine.

[0007] By adopting the above technical solution, the motor drives the track wheel to rotate, which in turn drives the track to move in a circular motion. The friction between the track and the surface of the pipe material is used to drive the pipe material to move smoothly along the preset conveying direction. The track structure can increase the contact area with the surface of the pipe material, disperse the pressure, and prevent the PTFE pipe material from being dented or scratched due to excessive local stress. At the same time, the stronger friction of the track can ensure that the pipe material does not slip during the conveying process, and adapt to the stable traction requirements of pipe materials of different diameters.

[0008] Furthermore, the clamping frame is provided in three sets, and the three sets of clamping frames are distributed in a circular array.

[0009] By adopting the above technical solution, the clamping frames of the three ring arrays can be positioned from three evenly distributed points on the outer periphery of the pipe, forming a stable triangular support structure, avoiding swaying or deviation of the pipe due to the shift of the center of gravity during the conveying process, and ensuring that the pipe is always conveyed along the preset path.

[0010] Furthermore, the clamping frame has a sliding groove inside, and the limiting rod is slidably connected to the clamping frame through the sliding groove.

[0011] By adopting the above technical solution, the chute and the limiting rod work together to provide guidance for the clamping frame. When the limiting frame rotates, the limiting rod can slide along the chute, causing the clamping frame to open or close synchronously, ensuring the consistency of the three sets of clamping frames and avoiding the deviation of the pipe positioning caused by the lag of the movement of a single clamping frame.

[0012] Furthermore, the toothed disc meshes with the rack.

[0013] By adopting the above technical solution, when the rack moves, it can drive the gear plate to rotate through meshing transmission, which converts the linear motion of the slide into the rotational motion of the limit frame, realizing the synchronous linkage between the traction machine spacing adjustment and the clamping frame opening / closing action, eliminating the need to operate the two mechanisms separately and improving the adjustment efficiency when changing the pipe diameter.

[0014] Furthermore, the limiting frame is rotatably connected to the fixed frame.

[0015] By adopting the above technical solution, the limiting frame can rotate around the central axis of the fixed frame, ensuring that when the gear plate drives the limiting frame to rotate, the limiting rod can stably push the clamping frame to move. At the same time, the fixed frame provides support for the limiting frame, avoiding inaccurate positioning of the clamping frame due to force deviation of the limiting frame.

[0016] Furthermore, the clamping frame is rotatably connected to the connecting rod.

[0017] By adopting the above technical solution, when the limiting rod pushes the clamping frame, the clamping frame can rotate around the connection point of the connecting rod, realizing flexible adjustment of the opening angle to adapt to the clamping requirements of different pipe diameters. At the same time, the rotating connection can reduce the rigid friction between components and extend the service life of the clamping frame.

[0018] Furthermore, a crank handle is connected to the top of the screw, and the crank handle has friction texture.

[0019] By adopting the above technical solution, the crank provides a labor-saving operating point for the screw rotation, making it convenient for operators to manually adjust the position of the slide; the friction texture at the grip can increase the friction between the hand and the crank, preventing the hand from slipping due to sweat during adjustment, and improving the safety and convenience of operation.

[0020] Furthermore, the connecting plate is L-shaped, the connecting plate is slidably connected to the guide rod, and the connecting plate is threadedly connected to the screw.

[0021] By adopting the above technical solution, the "L"-shaped structure can connect the slide and the rack simultaneously, ensuring that the rack moves synchronously when the slide moves; the sliding connection between the connecting plate and the guide rod can prevent the connecting plate from rotating with the screw and only making linear movements along the guide rod. At the same time, the threaded connection with the screw can convert the rotational motion of the screw into the linear motion of the connecting plate, realizing the synchronous linkage of the traction machine spacing adjustment and the opening / closing action of the clamping frame.

[0022] Furthermore, the bottom of the mounting cabinet is connected to four casters, which are arranged in a rectangular array.

[0023] By adopting the above technical solution, the four rectangular array of wheels provides the equipment with flexible mobility, allowing a single worker to push the equipment to adjust the production station without the need for multiple people to work together to move it, thus reducing labor costs; at the same time, the rectangular distribution ensures the stability of the equipment when it moves, preventing the equipment from tipping over due to imbalance of the center of gravity.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting up a linkage structure between the adjustment component and the fixing component, allows the slide to move in the opposite direction along the guide rod when the operator cranks the crank to drive the screw. At the same time, the connecting plate drives the rack to rotate the gear plate through meshing transmission, driving the clamping frame to open / close synchronously, realizing the synchronous adjustment of the traction machine spacing and clamping limit, solving the problem of traditional equipment requiring separate operation and low adjustment efficiency, and adapting to the needs of rapid replacement of different types of pipe materials.

[0026] 2. This utility model utilizes the combination of a tracked traction machine and a ball bearing clamping structure. The tracked traction machine increases the contact area of ​​the pipe material to avoid damage, while three sets of annular clamping frames work with the ball bearings to achieve stable positioning of the pipe material. At the same time, the ball bearings can reduce the frictional resistance during pipe material transportation, ensuring the stability of pipe material transportation and preventing scratches on the pipe material surface, thereby improving the production quality of polytetrafluoroethylene pipe materials.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1: A conveying structure for a polytetrafluoroethylene (PTFE) pipe production equipment, such as... Figures 1-4 As shown, the system includes a mounting cabinet 1. The top of the mounting cabinet 1 is equipped with an adjustment assembly 2, which includes a mounting frame 201. The bottom of the mounting frame 201 is connected to a guide rod 202 and a screw 203. Two slide blocks 204 are externally connected to the guide rod 202 and the screw 203. A traction machine body 3 is mounted on the outside of each slide block 204. A rack 4 is connected to the top of one of the slide blocks 204 via a connecting plate 205. A fixing assembly 5 is mounted on one side of the top of the mounting cabinet 1. The fixing assembly 5 includes a fixing frame 501. A limit frame 502 is connected inside the fixing frame 501. A clamping frame 504 is connected to one side of the fixing frame 501 via a connecting rod 503. The clamping frame 504 is connected to a ball bearing 506 at one end, the limiting frame 502 is connected to a limiting rod 505 inside, and the limiting frame 502 is connected to a toothed disc 6 outside. The main body of the traction machine 3 is a tracked traction machine. The motor drives the track wheel to rotate and drive the track to circulate. By utilizing the friction between the track and the surface of the pipe, the pipe is driven to move smoothly along the preset conveying direction. The tracked structure can increase the contact area with the surface of the pipe, disperse the pressure, and avoid the polytetrafluoroethylene pipe from having surface dents or scratches due to excessive local stress. At the same time, the friction of the track is stronger, which can ensure that the pipe does not slip during the conveying process and adapt to the stable traction requirements of pipes of different diameters.

[0035] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, the clamping frame 504 is provided in three sets, and the three sets of clamping frames 504 are distributed in a ring array. The three sets of ring array clamping frames 504 can be positioned from three evenly distributed points on the outer periphery of the pipe, forming a stable triangular support structure, avoiding shaking or deviation of the pipe due to the shift of the center of gravity during pipe transportation, and ensuring that the pipe is always transported along the preset path.

[0036] See Figure 3 and Figure 4 In the above embodiment, the clamping frame 504 is provided with a sliding groove 507, and the limiting rod 505 is slidably connected to the clamping frame 504 through the sliding groove 507. The sliding groove 507 and the limiting rod 505 cooperate to provide guidance for the clamping frame 504. When the limiting frame 502 rotates, the limiting rod 505 can slide along the sliding groove 507, driving the clamping frame 504 to open or close synchronously, ensuring the consistency of the actions of the three sets of clamping frames 504, and avoiding the deviation of the tube positioning caused by the lag in the action of a single clamping frame 504.

[0037] See Figure 3 and Figure 4 In the above embodiment, the gear disk 6 meshes with the rack 4. When the rack 4 moves, it can drive the gear disk 6 to rotate through meshing transmission, converting the linear motion of the slide 204 into the rotational motion of the limit frame 502, realizing the synchronous linkage between the traction machine spacing adjustment and the opening / closing action of the clamping frame 504, eliminating the need to operate the two mechanisms separately, and improving the adjustment efficiency when changing the pipe diameter.

[0038] See Figures 1-4 In the above embodiment, the limiting frame 502 is rotatably connected to the fixed frame 501. The limiting frame 502 can rotate around the central axis of the fixed frame 501, ensuring that when the gear plate 6 drives the limiting frame 502 to rotate, the limiting rod 505 can stably push the clamping frame 504 to move. At the same time, the fixed frame 501 provides support for the limiting frame 502, avoiding the clamping frame 504 from being inaccurately positioned due to the limit frame 502 being offset by force.

[0039] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, the clamping frame 504 is rotatably connected to the connecting rod 503. When the limiting rod 505 pushes the clamping frame 504, the clamping frame 504 can rotate around the connection point of the connecting rod 503, so as to realize the flexible adjustment of the opening angle and adapt to the clamping requirements of different pipe diameters. At the same time, the rotatable connection can reduce the rigid friction between components and extend the service life of the clamping frame 504.

[0040] See Figure 1 and Figure 2 In the above embodiment, a crank handle 206 is connected to the top of the screw 203, and the handle 206 has friction texture at the grip. The crank handle 206 provides a labor-saving operating point for rotating the screw 203, making it convenient for the operator to manually adjust the position of the slide block 204. The friction texture at the grip can increase the friction between the hand and the crank handle 206, preventing the hand from slipping due to sweat during adjustment, and improving the safety and convenience of operation.

[0041] See Figures 1-3In the above embodiment, the connecting plate 205 is L-shaped. The connecting plate 205 is slidably connected to the guide rod 202 and threadedly connected to the screw 203. The L-shaped structure can simultaneously connect the slide 204 and the rack 4, ensuring that the slide 204 moves synchronously and drives the rack 4 to move. The slidable connection between the connecting plate 205 and the guide rod 202 can prevent the connecting plate 205 from rotating with the screw 203 and only making linear movements along the guide rod 202. At the same time, the threaded connection with the screw 203 can convert the rotational motion of the screw 203 into the linear motion of the connecting plate 205, realizing the synchronous linkage of the traction machine spacing adjustment and the opening / closing action of the clamping frame 504.

[0042] Example 2: To facilitate flexible adjustment of the equipment position, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 and Figure 2 The bottom of the mounting cabinet 1 is connected to four movable wheels 7, which are arranged in a rectangular array. The four rectangular array of movable wheels 7 provides the equipment with flexible mobility. The staff can push the equipment to adjust the production station by one person without the need for multiple people to cooperate in the handling, thus reducing labor costs. At the same time, the rectangular distribution can ensure the stability of the equipment when it moves, and avoid the equipment from tipping over due to imbalance of the center of gravity.

[0043] The implementation principle of this utility model is as follows: When changing to produce different types of pipe materials, the operator cranks the handle 206 to drive the screw 203 to rotate. The screw 203 drives the tracked traction machine body 3 on the two slides 204 to move in opposite directions until the distance between the two traction machines is greater than the diameter of the pipe material to be transported. At the same time, driven by the slides 204, the connecting plate 205 drives the rack 4 to move synchronously. The rack 4 meshes with the gear plate 6, driving the gear plate 6 and the limiting frame 502 to rotate. When the limiting frame 502 rotates, the limiting rod 505 inside it slides along the groove 507 of the clamping frame 504, pushing the three sets of clamping frames 504 to open synchronously around the connecting rod 503, so that the clamping frames 504 The maximum distance between them is greater than the diameter of the pipe. Then, one end of the cooled and formed PTFE pipe is passed through the center of the fixed frame 501 and extended between the two traction machine bodies 3. Then, the crank 206 is rocked in the opposite direction, and the screw 203 drives the slide 204 to move in the opposite direction, so that the tracks of the two traction machine bodies 3 are in contact with the outer surface of the pipe. At the same time, the rack 4 moves in the opposite direction, which drives the gear plate 6 and the limit frame 502 to rotate in the opposite direction. The limit rod 505 pulls the clamping frame 504 to close synchronously, so that the ball 506 is in contact with the outer circumference of the pipe, limiting the longitudinal sway of the pipe. Finally, the traction machine body 3 is started, and the track drives the pipe to move stably along the conveying direction through friction, completing the pipe conveying.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
