Description

Technical Field

[0001] This utility model relates to the technical field of winding pultrusion equipment, specifically a noise-reducing winding pultrusion equipment. Background Technology

[0002] The filament winding pultrusion process, which drives fiber bundles continuously through impregnation, molding, and curing molds via a traction system, is a core technology for preparing high-performance composite profiles. As a key component for power transmission, the stability and noise control level of the transmission mechanism directly affect product quality and the production environment.

[0003] In pultrusion equipment, the transmission of the film frame mechanism is mostly achieved by chains. However, during use, the slack of the transmission chain can cause periodic "clicking" noises, affecting the stability of equipment operation and noise control. In this case, it is necessary to compensate for the slack of the chain.

[0004] Existing equipment mostly uses a fixed wheelbase or manually adjustable tensioning structure to compensate for chain slack. It relies entirely on operators to periodically adjust the position of the tensioning wheel with bolts. It cannot respond in real time to changes in chain length caused by wear and temperature changes. This can easily lead to insufficient tension causing chain tooth skipping and slippage, or excessive tension causing overload of the sprocket bearings. Both situations will aggravate mechanical vibration and generate high-frequency friction noise.

[0005] In view of this, a noise-reducing filament pultrusion device is provided to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a noise-reducing filament winding and pultrusion device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a noise-reducing winding pultrusion device, including a film carrier mechanism body, a base frame, and a riser frame. One end of the film carrier mechanism body is fixedly connected to a driven sprocket. A drive motor is fixedly installed on the top surface of the riser frame. A drive sprocket is drivenly connected to one side of the drive motor. Chains are sleeved on the outer walls of both the drive sprocket and the driven sprocket. A mounting frame is fixedly installed on the top surface of the base frame. A through groove is opened inside the mounting frame. A guide post is fixedly installed inside the through groove. A movable block is sleeved on the outer wall of the guide post. A compensation spring is fixedly connected to the bottom of the movable block. A rotatable compensation wheel is installed on one side of the movable block. The chain engages with the outer wall of the compensation wheel.

[0008] Furthermore, a limiting groove is formed on the side wall of the through groove, and there are two limiting grooves. The moving block is adapted to both the through groove and the limiting groove.

[0009] Furthermore, a support block is fitted at the bottom of the outer wall of the guide post, and the support block is adapted to both the through groove and the limiting groove.

[0010] Furthermore, a rotatable threaded rod is installed at the bottom of the inner wall of one side of the limiting groove, and the support block is threadedly connected to the outer wall of the threaded rod.

[0011] Furthermore, the end of the compensation spring furthest from the moving block is fixedly connected to the top surface of the support block.

[0012] Furthermore, a rotatable knob is installed on the bottom surface of the base frame, and the knob is fixedly connected to the threaded rod.

[0013] Furthermore, four slots are provided on the edge of the knob, and the specific shape of the slots is semi-circular.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting a compensating spring and positioning the moving block and compensating wheel above the compensating spring, the compensating spring can provide dynamic support to the chain, keeping the chain in a suitable operating state and preventing excessive noise, thus increasing the overall practicality of the device.

[0016] 2. By setting a support block and a threaded rod, and fixing a compensating spring to the top surface of the support block, the distance between the compensating spring and the moving block can be adjusted, allowing precise control of the preload provided by the compensating wheel to the chain. By adjusting the threaded rod to change the initial compression of the compensating spring, the support provided by the compensating wheel to the chain is prevented from being too tight or too loose. This ensures that the device can provide appropriate support when winding and pulling different profiles, preventing the chain from making abnormal noises due to loosening.

[0022] 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. Example

[0023] See Figure 1-4 A noise-reducing pultrusion winding device includes a film frame mechanism body 1, a base frame 2, and an extension frame 3. One end of the film frame mechanism body 1 is fixedly connected to a driven sprocket 7. A drive motor 4 is fixedly installed on the top surface of the extension frame 3. A drive sprocket 8 is drivenly connected to one side of the drive motor 4. A chain 6 is sleeved on the outer wall of both the drive sprocket 8 and the driven sprocket 7. An installation frame 5 is fixedly installed on the top surface of the base frame 2. A through groove 13 is opened inside the installation frame 5. A guide post 11 is fixedly installed inside the through groove 13. A movable block is sleeved on the outer wall of the guide post 11. A compensation spring 12 is fixedly connected to the bottom of the movable block. A rotatable compensation wheel 9 is installed on one side of the movable block. The chain 6 is engaged with the outer wall of the compensation wheel 9.

[0024] Furthermore, a limiting groove 14 is provided on the side wall of the through groove 13. There are two limiting grooves 14. The moving block is adapted to both the through groove 13 and the limiting groove 14. A support block 15 is sleeved on the bottom of the outer wall of the guide post 11. The support block 15 is adapted to both the through groove 13 and the limiting groove 14.

[0025] By setting the moving block to be compatible with both the through groove 13 and the limiting groove 14, and the support block 15 to be compatible with both the through groove 13 and the limiting groove 14, the moving block and the support block 15 will not easily deviate during the movement, and can only move along the axial direction of the guide post 11 inside the through groove 13.

[0026] Furthermore, a rotatable threaded rod 16 is installed at the bottom of the inner wall of the limiting groove 14 on one side, and a support block 15 is threadedly connected to the outer wall of the threaded rod 16. The end of the compensating spring 12 away from the moving block is fixedly connected to the top surface of the support block 15. A rotatable knob 10 is installed on the bottom surface of the base frame 2, and the knob 10 is fixedly connected to the threaded rod 16.

[0027] By setting the support block 15 to be threadedly connected to the outer wall of the threaded rod 16, the user can rotate the threaded rod 16 to drive the support block 15 to rise and fall, thereby adjusting the distance between the compensation spring 12 and the moving block. This allows for precise control of the preload provided by the compensation wheel 9 to the chain 6. By adjusting the threaded rod 16, the initial compression of the compensation spring 12 can be changed, preventing the compensation wheel 9 from providing too tight or too loose support to the chain 6. This ensures that the device can provide appropriate support when winding and pulling different profiles, preventing the chain 6 from making abnormal noises due to loosening.

[0028] In addition, four slots are provided on the edge of the knob 10, and the specific shape of the slots is semi-circular.

[0029] By setting the knob 10 and setting four semi-circular slots on the edge of the knob 10, the user can more easily rotate the threaded rod 16 through the knob 10.

[0030] In practice, when the membrane frame mechanism body 1 is working, the chain 6 on the outer wall of the driven sprocket 7 and the drive sprocket 8 is prone to loosening during use, which will cause abnormal noise in the membrane frame mechanism body 1 during operation, affecting the use of the device and the surrounding working environment.

[0031] In this practical application, when the chain 6 becomes slack, the compensation wheel 9 will directly lift one step of the chain 6 outward, so that the chain 6 is always tightly fitted on the outer wall of the driven sprocket 7 and the drive sprocket 8. Because the compensation wheel 9 is rotatably mounted on the outer wall of the moving block, and the moving block and the support block 15 are fixedly connected by a compensation spring 12, the compensation wheel 9 is lifted upward under the elastic force of the compensation spring 12, so that part of the chain 6 is lifted, so that the chain 6 will not easily become slack, thereby reducing the noise generated by the device.

[0032] By setting a compensation spring 12 and positioning the moving block and compensation wheel 9 above the compensation spring 12, the compensation spring 12 can provide dynamic support to the chain 6, ensuring that the chain 6 always maintains a suitable operating state and does not easily generate excessive noise, thus increasing the overall practicality of the device.

[0033] By setting up a support block 15 and a threaded rod 16, and fixing a compensation spring 12 to the top surface of the support block 15, the distance between the compensation spring 12 and the moving block can be adjusted, thereby precisely controlling the preload provided by the compensation wheel 9 to the chain 6. By adjusting the threaded rod 16 to change the initial compression of the compensation spring 12, the support provided by the compensation wheel 9 to the chain 6 is prevented from being too tight or too loose, so that the device can provide appropriate support when facing different profiles for winding and pulling, and prevent the chain 6 from making abnormal noise due to loosening.

[0034] Working principle: When the membrane frame mechanism body 1 is working, the chain 6 on the outer wall of the driven sprocket 7 and the drive sprocket 8 is prone to loosening during use, which will cause abnormal noise in the membrane frame mechanism body 1 during operation, affecting the use of the device and the surrounding working environment.

[0035] In this practical application, when the chain 6 becomes slack, the compensation wheel 9 will directly lift one step of the chain 6 outward, so that the chain 6 is always tightly fitted on the outer wall of the driven sprocket 7 and the drive sprocket 8. Because the compensation wheel 9 is rotatably mounted on the outer wall of the moving block, and the moving block and the support block 15 are fixedly connected by a compensation spring 12, the compensation wheel 9 is lifted upward under the elastic force of the compensation spring 12, so that part of the chain 6 is lifted, so that the chain 6 will not easily become slack, thereby reducing the noise generated by the device.

[0036] By setting a compensation spring 12 and positioning the moving block and compensation wheel 9 above the compensation spring 12, the compensation spring 12 can provide dynamic support to the chain 6, ensuring that the chain 6 always maintains a suitable operating state and does not easily generate excessive noise, thus increasing the overall practicality of the device.

[0037] By setting up a support block 15 and a threaded rod 16, and fixing a compensation spring 12 to the top surface of the support block 15, the distance between the compensation spring 12 and the moving block can be adjusted, so that the preload provided by the compensation wheel 9 to the chain 6 can be precisely controlled. By adjusting the threaded rod 16 to change the initial compression of the compensation spring 12, the support provided by the compensation wheel 9 to the chain 6 is prevented from being too tight or too loose, so that the device can provide appropriate support when facing different profiles for winding and pulling, and prevent the chain 6 from making abnormal noise due to loosening.

[0038] 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.
