Description

Technical Field

[0001] This utility model relates to the field of sealing strip processing technology, and more specifically to a traction device for sealing strip processing. Background Technology

[0002] Sealing strips are products used to seal something, making it difficult to open. They serve functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials, including rubber, paper, metal, and plastic. Since the 1980s, sealing strips have been applied to various industries such as automobiles, doors and windows, cabinets, refrigerators, and containers. Based on the requirements of different industries, unique automotive sealing strips, mechanical sealing strips, and door and window sealing strips have been developed.

[0003] A search revealed an existing patent (publication number: CN216004634U) that discloses a traction device for processing sealing strips. In its operation, a first and second transmission roller are configured, with a motor driving the second transmission roller via gears. The two transmission rollers are then connected by a chain, facilitating the cooperation between the first and second transmission rollers to move the sealing strip body, thus improving practicality. However, the inventors discovered the following problems with the existing technology during the development of this invention: In the aforementioned traction device, the sealing strip is clamped between the first and second transmission rollers, and the motor drives the second transmission roller to rotate and move the sealing strip. During the traction process, the contact area between the second transmission roller and the sealing strip is small, making slippage prone to occur. Furthermore, the small surface area of ​​the sealing strip makes it susceptible to twisting and deformation of the contact area under friction, affecting the quality of the sealing strip product.

[0004] In view of this, the present invention proposes a traction device for processing sealing strips to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a traction device for processing sealing strips to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a traction device for processing sealing strips, including a traction frame, a traction cavity is opened inside the traction frame, a support roller is rotatably connected to the inner bottom wall of the traction cavity, a sealing strip body is laid on the surface of the support roller, and two traction components are arranged on the inner wall of the traction frame corresponding to the sealing strip body, and the two traction components are linearly distributed.

[0007] The traction assembly includes a window at the top of the traction frame, with a transverse lead screw rotatably connected to the inner wall of the window. A reciprocating motor for driving the transverse lead screw is coaxially fixed at the end of the traction frame. A movable seat is threaded onto the surface of the transverse lead screw, and a hydraulic rod is embedded in the surface of the movable seat. A connecting seat is fixedly installed at the telescopic end of the hydraulic rod. A mounting seat is provided below the connecting seat, and a clamping seat is provided at the bottom of the mounting seat. A traction groove is provided at the bottom of the clamping seat, and the traction groove is adapted to the shape of the outer wall of the sealing strip body.

[0008] Furthermore, a limiting ring is provided on the surface of the support roller, and the sealing strip body is engaged inside the annular groove on the surface of the limiting ring.

[0009] As a further description of the above technical solution: by setting a limiting ring, the sealing strip body can be limited, preventing it from sliding back and forth on the surface of the support roller.

[0010] Furthermore, a limiting slide bar is fixedly installed on the inner wall of the window, and the movable seat is slidably connected to the surface of the limiting slide bar.

[0011] As a further description of the above technical solution: by setting a limit slide bar, the stability of the moving seat during movement can be ensured.

[0012] Furthermore, limit switches are symmetrically fixedly installed on the left and right inner walls of the window. The limit switches correspond to the end positions of the moving base and are connected to the reciprocating motor and hydraulic rod.

[0013] As a further description of the above technical solution: by setting a limit switch, the position of the moving seat can be monitored, and the rotation direction of the reciprocating motor and the extension and retraction of the hydraulic rod can be automatically controlled.

[0014] Furthermore, a balance slide bar is fixedly installed on the top of the connecting seat, and the balance slide bar is slidably connected to the surface of the movable seat.

[0015] As a further description of the above technical solution: by setting a balance slide bar, it is possible to prevent torsion at the extension and retraction end of the hydraulic rod, thus ensuring the stability of the connecting seat movement.

[0016] Furthermore, the surface of the mounting base is provided with mounting screws, and the clamping seat can be detachably mounted on the bottom side of the mounting base via the mounting screws.

[0017] As a further description of the above technical solution: During the use of the clamping seat, since the clamping seat is installed on the surface of the mounting seat by the mounting screw, the clamping seat can be replaced and adjusted when used for different models of sealing strip bodies.

[0018] Furthermore, the mounting base is movably mounted below the connecting base. A limiting buffer groove is laterally opened at the bottom end of the connecting base. The side cross-section of the limiting buffer groove is T-shaped. The mounting base is slidably connected inside the limiting buffer groove. A return spring is fixedly installed on the inner left wall of the limiting buffer groove. The right end of the return spring is fixed to the upper left of the mounting base.

[0019] As a further description of the above technical solution: the mounting base is slidably connected inside the limiting buffer groove, and the mounting base is flexibly supported by the return spring. When the sealing strip body is pulled to the right, the instantaneous force of the traction can be buffered, avoiding damage to the sealing strip body due to sudden traction force, thus achieving the effect of protecting it.

[0020] Furthermore, the inner top wall of the clamping seat is provided with a telescopic groove, the inner wall of the telescopic groove is slidably connected with a push-out block, and a support spring is fixedly installed on the inner top of the telescopic groove to drive the push-out block to move down and push the sealing strip body out of the traction groove.

[0021] As a further description of the above technical solution: by setting an ejector block and a support spring, when the hydraulic rod retracts and drives the clamping seat to rise, the support spring can drive the ejector block to move downward, so that the sealing strip body can be smoothly separated from the clamping seat, avoiding the situation of sticking.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] 1. Compared with existing technologies, this traction equipment for processing sealing strips lays the sealing strip body on the surface of the support roller. By setting up traction components, the hydraulic rod extends to drive the connecting seat, mounting seat, and clamping seat to move downwards, so that the clamping seat clamps the surface of the sealing strip body. Then, the reciprocating motor drives the transverse screw to rotate, which can drive the sealing strip body to move to the right. By using two traction components to alternately and cyclically traction the sealing strip body, a continuous traction effect can be achieved. During the traction process, the large contact area between the clamping seat and the sealing strip body can improve the clamping traction effect and avoid slippage. Furthermore, by increasing the area, the pressure at the contact point is reduced, thereby avoiding traction damage and ensuring the quality of the sealing strip body.

[0024] 2. Compared with existing technologies, this traction equipment for processing sealing strips can limit the sealing strip body by setting a limit ring, preventing it from sliding back and forth on the support roller surface; it can ensure the stability of the moving seat when moving by setting a limit slide bar; it can monitor the position of the moving seat by setting a limit switch, and automatically adjust the rotation direction of the reciprocating motor and the extension and retraction of the hydraulic rod; it can provide anti-torsion protection for the extension and retraction end of the hydraulic rod by setting a balance slide bar, ensuring the stability of the connecting seat movement.

[0025] 3. Compared with existing technologies, this traction device for processing sealing strips allows for easy replacement and adjustment of the clamping seat when used with different models of sealing strips, as the clamping seat is mounted on the surface of the mounting base via mounting screws. The mounting base is slidably connected inside the limiting buffer groove, and a return spring provides flexible support. When the sealing strip is pulled to the right, the instantaneous force of the traction is buffered, preventing damage to the sealing strip due to sudden traction force, thus achieving a protective effect. Furthermore, by incorporating a push-out block and a support spring, when the hydraulic rod retracts and drives the clamping seat to rise, the support spring drives the push-out block to move downwards, allowing the sealing strip to smoothly disengage from the clamping seat.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The traction device for processing sealing strips involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Reference Figures 1 to 4 This utility model provides a traction device for processing sealing strips, including a traction frame 1. The traction frame 1 has a traction cavity inside, and a support roller 2 is rotatably connected to the inner bottom wall of the traction cavity. The surface of the support roller 2 is covered with a sealing strip body 3.

[0033] A limiting ring 11 is provided on the surface of the support roller 2, and the sealing strip body 3 is engaged in the annular groove on the surface of the limiting ring 11.

[0034] By setting the limiting ring 11, the sealing strip body 3 can be limited, preventing it from sliding back and forth on the surface of the support roller 2.

[0035] The inner wall of the traction frame 1 is provided with two traction components corresponding to the sealing strip body 3, and the two traction components are linearly distributed.

[0036] The traction assembly includes a window opened at the top of the traction frame 1, a transverse lead screw 4 rotatably connected to the inner wall of the window, a reciprocating motor 5 coaxially fixed at the end of the traction frame 1 to drive the transverse lead screw 4 to rotate, and a movable seat 6 threadedly connected to the surface of the transverse lead screw 4.

[0037] A limiting slide bar 12 is fixedly installed on the inner wall of the window, and the movable seat 6 is slidably connected to the surface of the limiting slide bar 12.

[0038] By setting the limit slide bar 12, the stability of the moving seat 6 during movement can be ensured.

[0039] The surface of the movable seat 6 is fitted with a hydraulic rod 7, and the telescopic end of the hydraulic rod 7 is fixedly installed with a connecting seat 8.

[0040] A balance slide bar 19 is fixedly installed on the top of the connecting seat 8, and the balance slide bar 19 is slidably connected to the surface of the movable seat 6.

[0041] By setting the balance slide bar 19, the extension and retraction end of the hydraulic rod 7 can be protected against torsion, ensuring the stability of the movement of the connecting seat 8.

[0042] A mounting base 9 is provided below the connecting base 8, and a clamping base 10 is provided at the bottom end of the mounting base 9. A traction groove is provided at the bottom end of the clamping base 10, and the traction groove is adapted to the shape of the outer wall of the sealing strip body 3.

[0043] The traction equipment for processing sealing strips has a sealing strip body 3 laid on the surface of the support roller 2. By setting up a traction component, the hydraulic rod 7 extends to drive the connecting seat 8, mounting seat 9 and clamping seat 10 to move downward, so that the clamping seat 10 clamps the surface of the sealing strip body 3. Then, the reciprocating motor 5 drives the transverse lead screw 4 to rotate, which can drive the sealing strip body 3 to move to the right. Then, the hydraulic rod 7 is controlled to retract, the sealing strip body 3 disengages from the clamping seat 10, and drives the clamping seat 10 to move back to the left side position. By using two traction components to alternately and cyclically traction the sealing strip body 3, the effect of continuous traction of the sealing strip body 3 can be achieved.

[0044] It is worth noting that during the traction process, the large contact area between the clamping seat 10 and the sealing strip body 3 improves the clamping and traction effect, avoids slippage, and reduces the pressure at the contact point by increasing the area, thereby avoiding traction damage and ensuring the quality of the sealing strip body 3.

[0045] Limit switches 13 are symmetrically fixedly installed on the left and right inner walls of the window. The limit switches 13 correspond to the end positions of the moving base 6. The limit switches 13 are connected to the reciprocating motor 5 and the hydraulic rod 7.

[0046] It is worth noting that by setting the limit switch 13, the position of the moving seat 6 can be monitored, and the rotation direction of the reciprocating motor 5 and the extension and retraction of the hydraulic rod 7 can be automatically controlled.

[0047] Mounting screws 14 are provided on the surface of mounting base 9, and clamping base 10 can be detachably mounted on the bottom side of mounting base 9 via mounting screws 14.

[0048] Furthermore, since the clamping seat 10 is mounted on the surface of the mounting seat 9 via the mounting screw 14, the clamping seat 10 can be replaced and adjusted when used for different models of sealing strip bodies 3, making it flexible in use.

[0049] Mounting base 9 is movably mounted below connecting base 8. A limiting buffer groove 15 is horizontally opened at the bottom end of connecting base 8. The side section of the limiting buffer groove 15 is T-shaped. Mounting base 9 is slidably connected inside the limiting buffer groove 15. A return spring 16 is fixedly installed on the inner left wall of the limiting buffer groove 15. The right end of the return spring 16 is fixed to the upper left of mounting base 9.

[0050] It is worth noting that by sliding the mounting base 9 inside the limiting buffer groove 15 and using the return spring 16 to flexibly support the mounting base 9, when the sealing strip body 3 is pulled to the right, the instantaneous force of the pull can be buffered, avoiding damage to the sealing strip body 3 due to sudden pulling force, thus achieving the effect of protecting it.

[0051] The inner top wall of the clamping seat 10 is provided with a telescopic groove, and the inner wall of the telescopic groove is slidably connected with a push-out block 17. A support spring 18 is fixedly installed on the inner top of the telescopic groove to drive the push-out block 17 to move down and push the sealing strip body 3 out of the traction groove.

[0052] It is worth noting that by setting the push-out block 17 and the support spring 18, when the clamping seat 10 moves down and engages with the sealing strip body 3, the push-out block 17 is retracted into the telescopic groove under the action of pressing. When the hydraulic rod 7 retracts and drives the clamping seat 10 to rise, the support spring 18 can drive the push-out block 17 to move down, ensuring that the sealing strip body 3 is smoothly disengaged from the clamping seat 10.

[0053] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
