Filter cloth calender tension roller

Abstract

This utility model discloses a tension roller for a filter cloth calender, relating to the field of calender technology. It includes a base plate, with a mounting frame fixedly installed on the top of the base plate. A movable block is movably installed on one side of the mounting frame. A first mounting groove is formed inside the movable block, and a round rod is fixedly installed on one side of the inner wall of the first mounting groove. A slider is slidably sleeved on the outer side of the round rod. This utility model, by placing the tension roller tightly against the bottom of the filter cloth, allows the filter cloth to slide on top of the tension roller. When the filter cloth is taut, the tension roller moves downwards under force, causing the mounting frame to move downwards. The mounting frame, through a mounting seat, drives a connecting rod to move. One end of the connecting rod causes a slider to slide on the outer side of the round rod. The two sliders approach each other, and a telescopic spring is compressed between the two sliders. The damper and damping spring are compressed under force, producing deformation. The force is distributed and transmitted through the connecting rod, slider, and other components, resulting in more even force distribution among the components and maintaining the buffering effect of the tension roller.

Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically to the tension roller of a filter cloth calendering machine. Background Technology

[0002] The tension roller of the filter cloth calender is a key component used to maintain the tension of the filter cloth. Its main function is to keep the filter cloth flat and taut during the calendering process, so as to ensure that the calendering effect is uniform and consistent, and to prevent problems such as wrinkles and deviation of the filter cloth.

[0003] An existing Chinese patent (publication number CN221318606U) discloses an adaptive tension roller mechanism. The mechanism uses a drive motor to rotate a threaded rod, which in turn drives a lifting plate to move. The lifting plate then moves the tension roller. By adjusting the height of the tension roller, the tension of the fabric on it can be controlled, thus achieving the adjustment of the tension of fabrics of different materials. The adjustment is simple and convenient, and it has good applicability.

[0004] However, when using the adaptive tensioning roller mechanism designed above, the tension is adjusted by causing the limiting block and limiting rod to reciprocate in the vertical direction with the tensioning roller, which deforms the first and second springs and maintains the stability of the tension. However, the force transmission path is single and concentrated. The first and second springs are repeatedly compressed or stretched over a long period of time, which can easily lead to a decrease in the elastic coefficient and a weakening of the deformation ability due to excessive local stress. This results in unstable tension, failure of the buffering effect, and damage to the fabric.

[0005] To address these issues, we designed a tension roller for the filter cloth calender. Utility Model Content

[0006] The purpose of this invention is to provide a tension roller for a filter cloth calender to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a tension roller for a filter cloth calender, comprising a base plate, a mounting frame fixedly installed on the top of the base plate, a movable block movably installed on one side of the mounting frame, a first mounting groove opened inside the movable block, a round rod fixedly installed on one side of the inner wall of the first mounting groove, and a slider slidably sleeved on the outer side of the round rod, the number of sliders being provided is two, the two sliders being symmetrically arranged on both sides of the base plate with the vertical axis of the round rod as the center, a telescopic spring fixedly connected to the opposite side of the two sliders, a connecting rod movably connected to one side of the slider, a mounting frame provided at one end of the connecting rod, and a tension roller movably installed inside the mounting frame.

[0008] Furthermore, a screw is rotatably mounted on one side of the inner wall of the mounting bracket. The screw is threaded into the interior of the movable block. There are two screws, both of which are rotatably mounted on the top of the base plate. A second mounting groove is provided inside the base plate. A synchronous pulley is rotatably mounted inside the second mounting groove. The synchronous pulley is fixedly connected to the screw via a rotating shaft. A synchronous belt is tensioned together on the outer sides of the two synchronous pulleys.

[0009] Furthermore, a rotating motor is fixedly mounted on the top of the mounting bracket, and the drive end of the rotating motor is fixedly connected to the screw.

[0010] Furthermore, a damper is fixedly installed on the top of the movable block, and the driving end of the damper is fixedly connected to the bottom of the mounting frame.

[0011] Furthermore, a damping spring is sleeved on the outside of the damper, one end of the damping spring is fixedly connected to one side of the moving block, and the other end of the damping spring is fixedly connected to the mounting frame.

[0012] Furthermore, a mounting base is fixedly installed at the bottom of the mounting frame, and the mounting base is rotatably connected to the end of the connecting rod away from the slider.

[0013] Furthermore, a rotating shaft is fixedly connected to one side of the tensioning roller, and the tensioning roller is rotatably connected to the mounting frame through the rotating shaft.

[0014] Furthermore, the number of dampers is set to two, and the number of damping springs matches the number of dampers. The two dampers are symmetrically arranged on both sides of the top of the moving block with the vertical axis of the moving block as the center.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The operator places the tension roller tightly under the filter cloth. The filter cloth can slide on the top of the tension roller. When the filter cloth is taut, the tension roller moves downward under the force. The tension roller drives the mounting frame downward. The mounting frame drives the connecting rod to move through the mounting seat. One end of the connecting rod drives the slider to slide on the outside of the round rod. The two sliders move closer to each other. The telescopic spring is compressed between the two sliders. The damper and the damping spring are compressed under the force, producing deformation. The force is distributed and transmitted through the connecting rod, slider and other components, so that the force on each component is more even and the buffering effect of the tension roller is maintained.

[0017] 2. Start the rotating motor. The rotating motor drives the screw to rotate. Both ends of the moving block are threaded with screws. When the screws rotate, they drive the synchronous pulleys to rotate. The two synchronous pulleys are driven by a synchronous belt, so that the two screws on the top of the base plate rotate synchronously, which makes it easy to keep the two ends of the tension roller horizontal when moving the tension roller.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: including a base plate 1, a mounting frame 2 fixedly installed on the top of the base plate 1, a movable block 6 movably installed on one side of the mounting frame 2, a first mounting groove 7 opened inside the movable block 6, a round rod 8 fixedly installed on one side of the inner wall of the first mounting groove 7, a slider 9 slidably sleeved on the outer side of the round rod 8, two sliders 9 are provided, the two sliders 9 are symmetrically arranged on both sides of the base plate 1 with the vertical axis of the round rod 8 as the center, a telescopic spring 10 is fixedly connected to the opposite side of the two sliders 9, a connecting rod 11 is movably connected to one side of the slider 9, a mounting frame 15 is provided at one end of the connecting rod 11, a tension roller 3 is movably installed inside the mounting frame 15, a mounting seat 12 is fixedly installed at the bottom of the mounting frame 15, the mounting seat 12 is rotatably connected to the end of the connecting rod 11 away from the slider 9, a rotating shaft is fixedly connected to one side of the tension roller 3, and the tension roller 3 is rotatably connected to the mounting frame 15 through the rotating shaft.

[0025] In practice, the tension roller 3 is placed close to the bottom of the filter cloth, allowing the filter cloth to slide on top of the tension roller 3. When the filter cloth is taut, the tension roller 3 moves downward under force, which in turn moves the mounting frame 15 downward. The mounting frame 15 moves the connecting rod 11 through the mounting base 12. When the connecting rod 11 moves, one end of the connecting rod 11 moves the slider 9 to slide on the outside of the round rod 8. The two sliders 9 move closer to each other, and the telescopic spring 10 is compressed between the two sliders 9. The damper 13 and the damping spring 14 are compressed under force, causing deformation and buffering the tension force on the tension roller 3.

[0026] See Figure 2 and Figure 4 A screw 4 is rotatably mounted on one side of the inner wall of the mounting bracket 2. The screw 4 is threaded into the inside of the moving block 6. There are two screws 4, both of which are rotatably mounted on the top of the base plate 1. A second mounting groove 17 is provided inside the base plate 1. A synchronous wheel 16 is rotatably mounted inside the second mounting groove 17. The synchronous wheel 16 is fixedly connected to the screw 4 through a rotating shaft. A synchronous belt 18 is tensioned on the outer side of the two synchronous wheels 16. A rotary motor 5 is fixedly mounted on the top of the mounting bracket 2. The drive end of the rotary motor 5 is fixedly connected to the screw 4.

[0027] It should be noted that there are two mounting brackets 2, which are symmetrically arranged on the top of the base plate 1, and the rotating motor 5 is fixedly installed on the top of one of the mounting brackets 2.

[0028] In practice, when it is necessary to adjust the height of the tension roller 3 on the calender, the rotary motor 5 can be started. The rotary motor 5 drives the screw 4 to rotate. Both ends of the moving block 6 are threaded with screws 4. When the screws 4 rotate, they drive the synchronous pulleys 16 to rotate. The two synchronous pulleys 16 are driven by the synchronous belt 18, so that the two screws 4 at the top of the base plate 1 rotate synchronously. This makes it easier for the moving block 6 to move on the top of the base plate 1, improves the stability of the moving block 6, and keeps the tension roller 3 at the same height at both ends and horizontal when it moves with the moving block 6.

[0029] See Figure 3 A damper 13 is fixedly installed on the top of the movable block 6. The driving end of the damper 13 is fixedly connected to the bottom of the mounting frame 15. A damping spring 14 is sleeved on the outside of the damper 13. One end of the damping spring 14 is fixedly connected to one side of the movable block 6, and the other end of the damping spring 14 is fixedly connected to the mounting frame 15.

[0030] By setting up damper 13 and damping spring 14, multiple buffers are formed with telescopic spring 10, further optimizing the force buffering effect of tension roller 3. Damper 13 uses damping force to consume the energy of tension roller 3 moving downward, suppressing the violent vibration or rebound caused by sudden change in filter cloth tension, and avoiding excessive downward movement of tension roller 3 due to inertia, which would cause filter cloth to loosen. Damping spring 14 works with damper 13 to slow down the movement speed, making the force feedback of tension roller 3 more stable.

[0031] See Figure 2 There are two dampers 13, and the number of damping springs 14 matches the number of dampers 13. The two dampers 13 are symmetrically arranged on both sides of the top of the moving block 6 with the vertical axis of the moving block 6 as the center.

[0032] By setting two symmetrically distributed dampers 13 and matching damping springs 14, the tension roller 3 is subjected to uniform force at both ends, avoiding tilting of the tension roller 3 due to insufficient buffering force on one side, and preventing the filter cloth from running off-center or its edges from wearing out.

[0033] Working principle: When using the device, the operator places the tension roller 3 close to the bottom of the filter cloth, allowing the filter cloth to slide on top of the tension roller 3. When the filter cloth is taut, the tension roller 3 moves downward under force, which drives the mounting frame 15 to move downward. The mounting frame 15 drives the connecting rod 11 to move through the mounting base 12. When the connecting rod 11 moves, one end of the connecting rod 11 drives the slider 9 to slide on the outside of the round rod 8. The two sliders 9 move closer to each other, and the telescopic spring 10 is compressed between the two sliders 9. The damper 13 and the damping spring 14 are compressed under force, producing deformation, which buffers the tension force on the tension roller 3.

[0034] When it is necessary to adjust the height of the tension roller 3 on the calender, the rotary motor 5 can be started. The rotary motor 5 drives the screw 4 to rotate. Both ends of the moving block 6 are threaded with screws 4. When the screws 4 rotate, they drive the synchronous pulleys 16 to rotate. The two synchronous pulleys 16 are driven by the synchronous belt 18, so that the two screws 4 at the top of the base plate 1 rotate synchronously. This makes it easier for the moving block 6 to move on the top of the base plate 1, improves the stability of the moving block 6, and keeps the tension roller 3 at the same height at both ends when it moves with the moving block 6, so that the tension roller 3 remains horizontal.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
