Description

Technical Field

[0001] This application relates to the field of take-up roll movement buffers, and more particularly to a take-up roll movement buffer structure. Background Technology

[0002] During the operation of the laminating machine, the movement direction of the film is mainly guided by several guide rollers. As the film travels, the length of the film will also change due to temperature changes. Therefore, in order to ensure the film conveying efficiency, an additional guide roller buffer structure is usually set on the laminating machine to adjust the length of the film and maintain the tension of the film.

[0003] For example, the patent application with patent number 202021161180.9 discloses a guide roller buffer structure, but it still has the following shortcomings in actual use:

[0004] The aforementioned device includes a guide roller, left / right cylinders, a synchronization component (including rack and pinion gears) that works with a linkage rod to synchronously raise and lower both ends of the guide roller, a linkage rod, a slider, a buffer pad, a sensor plate, a stainless steel reflector, and a photosensor. This solves the problem of guide roller tilting due to stroke difference in left and right synchronization. During use, the cylinder drives the guide roller to rise and fall, requiring high lubrication. The piston and seals need to be regularly lubricated, otherwise they are prone to jamming and air leakage. The buffer parts are prone to corrosion after long-term exposure to the working environment, affecting the buffering performance and posing a hidden danger to the stable operation of the equipment. In addition, the buffer pad is not easy to replace and is prone to aging after long-term use, resulting in a decrease in the buffering effect. Utility Model Content

[0005] To improve the rust-prone nature of buffer parts and solve the problem of buffer pad replacement, this application provides a moving buffer structure for take-up rollers.

[0006] The technical solution for the winding roller movement buffer structure provided in this application is as follows:

[0007] A winding roller moving buffer structure includes a buffer frame and a slide rail fixed in the middle of the buffer frame. A buffer mechanism for buffering is slidably arranged on the outer side of the slide rail. A conveyor roller is rotatably arranged in the middle of one side of the buffer mechanism. A lubrication mechanism for lubricating the buffer mechanism is fixed in the middle of the buffer mechanism. Fixing mechanisms are symmetrically fixed at both ends of the middle of the buffer frame. The buffer mechanism includes a slider that slides in the middle of the slide rail and a rotating block that rotatably passes through both ends of the slider. A lead screw is threaded through the inside of the rotating block. A spring is fixed at the end of the lead screw away from the rotating block. The end of the spring away from the lead screw is fixed to the inner wall of the buffer frame. The lubrication mechanism includes an oil tank fixed at both ends of the slider and a baffle that slidably passes through the lower end of the oil tank. Springs are fixed at both ends of the baffle and fixed to the two sides of the inner wall of the oil tank.

[0008] By adopting the above technical solutions, the buffer frame and slide rail provide support and guidance for the overall structure. The buffer mechanism, through the cooperation of slider, rotating block, lead screw and spring, uses the elastic deformation of the spring and the axial movement of the lead screw to absorb the tension fluctuations of the wide plastic film, thus achieving dynamic buffering. The conveyor roller connects the buffer mechanisms on both sides to ensure synchronous movement and avoid tilting. The lubrication mechanism consists of an oil tank, baffle and spring to form an automatic oil injection system. When the buffer mechanism is running, it pushes the baffle to deliver lubricating oil to the lead screw and slider to prevent rust and jamming. The fixing mechanism absorbs the impact energy of the slider at the extreme position through the buffer pad, ensuring stable operation of the equipment.

[0009] Preferably, the inner wall of the rotating block is provided with a threaded groove that matches the thread on the surface of the lead screw, and a through hole is provided in the middle of the rotating block. A push rod is fixedly provided on the outer ring of one end of the rotating block, and a push rod is fixedly provided on the outer ring of the other end of the rotating block.

[0010] By adopting the above technical solution, the threaded groove and the lead screw thread cooperate to realize axial transmission to complete the buffer action, the through hole one is used to deliver lubricating oil to the surface of the lead screw, and the push rod one and push rod two realize the automatic oil injection function by rotating to trigger the lubrication mechanism.

[0011] Preferably, the slider has a circular hole and an oil leakage hole at both ends, and the middle part of the rotating block rotates through the circular hole.

[0012] By adopting the above technical solution, the circular hole allows the rotating block to rotate around the axis, and the oil leakage hole is connected with the through hole in the middle of the rotating block to form a lubricating oil delivery channel, ensuring that the lubricating oil can be accurately delivered to the surface of the lead screw.

[0013] Preferably, the end of the lead screw away from the rotating block is fixedly provided with a fixing block one that is fixed to the spring one, and the end of the spring one away from the fixing block one is fixedly provided with a fixing block two that is fixed to the inner wall of the buffer frame.

[0014] By adopting the above technical solution, the lead screw is connected to the spring through the fixing block one, and the spring is fixed to the inner wall of the buffer frame through the fixing block two, forming an elastic buffer system. When the lead screw moves axially, the spring can elastically deform to absorb tension energy and realize the dynamic buffer function.

[0015] Preferably, a partition plate is fixedly provided in the middle of the slider to separate the two lead screws.

[0016] By adopting the above technical solution, the separator plate isolates the two lead screws in the middle of the slider, preventing them from jamming due to mutual contact during synchronous movement, and ensuring the independent and stable operation of the dual lead screw buffer system.

[0017] Preferably, the baffle has a through hole 3 in the middle that communicates with the oil leakage hole, for transporting the lubricating oil inside the oil tank to the oil leakage hole.

[0018] By adopting the above technical solution, the three through holes in the middle of the baffle are aligned with the oil leakage hole to form a lubricating oil delivery channel. When the baffle slides, the three through holes open and close periodically to realize the quantitative and directional delivery of lubricating oil in the oil tank to the oil leakage hole, ensuring continuous lubrication of the lead screw.

[0019] Preferably, the concave surfaces at both ends of the slider are provided with through holes that communicate with the circular holes.

[0020] By adopting the above technical solution, the through holes on the concave surfaces of the slider are connected to the circular holes of the buffer frame, allowing lubricating oil to flow from the oil leakage hole to the contact surface between the slider and the slide rail, so that the slider is fully lubricated when sliding, reducing friction and wear.

[0021] Preferably, the fixing mechanism includes a fixing plate symmetrically fixed at both ends of the slider stroke and a buffer pad fixed at the lower end of the fixing plate. A plug is symmetrically inserted into one side of the fixing plate, and a spring is fixed in the middle of the two fixing plates.

[0022] By adopting the above technical solution, the fixing mechanism positions the slider at its travel limit by fixing plate, the buffer pad absorbs the impact energy of the slider to reduce impact damage, and the insert block and spring form an elastic locking structure to fix the fixing plate and the buffer pad.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By sliding the slider along the slide rail, the lead screw moves axially, causing the spring to compress or stretch. The elastic deformation of the spring and the axial displacement of the lead screw work together to dynamically absorb the energy generated by the tension fluctuations of the wide plastic film. At the same time, the rotating block rotates and pushes the baffle to slide, so that lubricating oil is delivered to the surface of the lead screw and the concave surface of the slider, preventing rust and jamming, and ensuring smooth cooperation between the spring and the lead screw, as well as between the slider and the slide rail, achieving a more stable and durable tension buffering effect. Compared with cylinder drive, this structure has a more sensitive buffering response and slower performance decay.

[0025] 2. By using the slots of the fixing plate to cooperate with the insert block, and utilizing the elastic force of spring three to make the insert block snap into the slot, the buffer pad can be quickly installed and replaced, solving the problem of decreased buffering effect after aging caused by the difficulty in replacing traditional buffer pads, and improving the convenience of equipment maintenance.

[0026] 3. When the slider slides to its limit distance, it impacts the buffer pad at the lower end of the fixed plate. The buffer pad absorbs the impact energy through elastic deformation, thereby realizing the impact of the buffer slider on the inner wall of the buffer frame, reducing equipment operating noise and extending the service life of components.

[0043] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0044] This application discloses a winding roller movement buffer structure.

[0045] Reference Figures 1-3 A winding roller moving buffer structure includes a buffer frame 1 and a slide rail 6 fixed in the middle of the buffer frame 1. The shape of the buffer frame 1 is as follows: Figure 2 As shown, the slide rail 6 consists of two rectangular blocks extending longitudinally along the buffer frame 1. The side of the slide rail 6 closest to the buffer frame 1 is fixedly connected to the inner wall of the buffer frame 1, providing guidance and a sliding track for the buffer mechanism 2. The buffer mechanism 2 is slidably mounted on the sliding surface of the slide rail 6. The two buffer mechanisms 2 together form a buffer structure. A conveyor roller 5 is rotatably mounted in the middle of the opposite side of the two buffer mechanisms 2. The buffer mechanism 2 is used to buffer the tension generated when the conveyor roller 5 stops rotating or rotates. At the same time, the conveyor roller 5 synchronizes the two buffer mechanisms 2 to avoid tilting of the conveyor roller 5 due to the difference in stroke. A lubrication mechanism 3 is fixedly mounted in the middle of the buffer mechanism 2. The lubrication mechanism 3 is used to lubricate the buffer mechanism 2 during operation to prevent the buffer mechanism 2 from being exposed to air for a long time or from rusting during use, which would reduce the buffering effect. Fixing mechanisms 4 are symmetrically fixed at both ends of the middle of the buffer frame 1.

[0046] Before use, the device is installed symmetrically on the film winding equipment in the film production and processing workshop, which is used to wind up the wide plastic film produced. Two slide rails 6 are installed on the inner wall of the buffer frame 1, and two buffer mechanisms 2 are slid on the outer side of the slide rails 6 respectively, so that the two form a buffer structure. A conveyor roller 5 is rotatably installed in the middle of the opposite side of the two buffer mechanisms 2 to ensure that the conveyor roller 5 can rotate normally. A lubrication mechanism 3 is fixedly installed in the middle of the buffer mechanism 2 for lubrication during subsequent operation. Fixing mechanisms 4 are symmetrically fixed at both ends of the middle of the buffer frame 1.

[0047] In use, the wide plastic film is wrapped around the bottom of the conveyor roller 5. The tension generated by the wide plastic film during the winding or unwinding process drives the conveyor roller 5 to rotate, and drives the two buffer mechanisms 2 to move synchronously along the longitudinal track of the guide block slide rail 6. When the conveyor roller 5 stops rotating due to operation pause, or when the wide plastic film is rewound and reverse tension is generated, the buffer mechanism 2 absorbs the tension energy by sliding along the slide rail 6, thereby achieving dynamic buffering of tension fluctuations. As the core component connecting the two buffer mechanisms 2, the conveyor roller 5 constrains the movement stroke of the two buffer mechanisms 2 by the synchronous rotation of the conveyor roller 5, avoiding the stroke difference caused by the tension difference on one side, thereby preventing the conveyor roller 5 from tilting. During operation, the buffer mechanism 2 drives the lubrication mechanism 3 to move synchronously. The lubrication mechanism 3 continuously lubricates the buffer mechanism 2, avoiding rust problems caused by long-term exposure to air or wear and tear, and ensuring the stable buffering performance of the buffer mechanism 2.

[0048] Reference Figure 4 , Figure 5 , Figure 9 The buffer mechanism 2 includes a slider 201 that slides in the middle of the slide rail 6 and rotating blocks 202 that rotatably pass through both ends of the slider 201. The shape of the slider 201 is as follows (e.g., Figure 4 As shown, the slider 201 has grooves on both sides, the shape and size of which are adapted to the shape of the slide rail 6. The slider 201 slides in the middle of the slide rail 6 through the grooves. The inner wall of the rotating block 202 is threaded with a lead screw 203. The inner ring of the rotating block 202 has a threaded groove 212, which is adapted to the thread on the surface of the lead screw 203. The lead screw 203 passes through the threaded groove 212 and is threaded through the middle of the rotating block 202. The two ends of the slider 201 are respectively provided with a circular hole 209 and an oil leakage hole 210. Both sides of the concave surface of the slider 201 are provided with through holes 214. The through holes 214 are connected to the circular holes 209. The circular holes 209 are located in the middle of the upper and lower ends of the buffer frame 1. One oil leakage hole 210 is located on one side of the circular holes 209 at the top of the slider 201, and the other oil leakage hole 210 is located on one side of the circular holes 209 on the inner bottom surface of the slider 201. The oil leakage holes 210 are connected to the circular holes 209. The middle of the two rotating blocks 202 are rotated through the two ends of the slider 201 via the circular holes 209.

[0049] In use, the movement of the conveyor roller 5 drives the slider 201 to slide longitudinally on the slide rail 6, causing the rotating block 202 to drive the lead screw 203 to move axially along the rotating block 202, thereby compressing or stretching the spring 205. The elastic force of the spring 205 is transmitted to the inner walls of both ends of the buffer frame 1 through the fixed block 206, forming an elastic constraint on the displacement of the lead screw 203. The elastic deformation of the spring 205 and the axial movement of the lead screw 203 work together to achieve the functions of buffering and force adjustment.

[0050] Both rotating blocks 202 have through holes 211 in their middle sections. The axis of through hole 211 coincides with the axis of through hole 214. Through hole 211 communicates with oil drain hole 210 through circular hole 209, allowing lubricating oil from inside oil drain hole 210 to be transferred to the surface of lead screw 203. A push rod 207 is fixed to the outer ring of one rotating block 202 located outside slider 201, and a push rod 213 is fixed to the outer ring of the other rotating block 202 located inside slider 201. Push rods 207 and 213 trigger baffle 302 to control the opening and closing of the lubrication system. A fixing block 204 is fixed to the end of lead screw 203 away from rotating blocks 202. A spring 205 is fixed at the end of block 204 away from the lead screw 203. The formula for calculating the elastic force of spring 205 is F = kx, where F represents the elastic force of spring 205, k represents the constant of spring 205, and x represents the compression of spring 205. A fixing block 206 is fixed at the end of spring 205 away from fixing block 204. The two ends of spring 205 are fixed to the opposite side of fixing block 204 and fixing block 206, respectively. The ends of the two fixing blocks 206 away from spring 205 are fixed to the inner walls of the two ends of the buffer frame 1, respectively. Spring 205 needs to be reasonably selected according to actual needs, ensuring spring quality, and avoiding overload and harsh environment.

[0051] A partition plate 208 is fixed in the middle of the inner wall of the slider 201. When the two lead screws 203 rotate to their limit distance, their opposite ends abut against the two sides of the partition plate 208. The partition plate 208 is made of polytetrafluoroethylene. This type of material is wear-resistant, oil-resistant and has good self-lubricating properties. It is suitable for long-term resistance to the impact of the lead screws 203 and the lubricating oil environment. It is used to isolate the opposite ends of the two lead screws 203 and to buffer when the two lead screws 203 rotate to their limit distance.

[0052] Meanwhile, when the rotating block 202 rotates, because the through hole 211 inside the rotating block 202 is connected to the circular hole 209 and the oil leakage hole 210, the lubricating oil in the oil leakage hole 210 is transported through the through hole 211 to the surface of the lead screw 203 and the concave surfaces on both sides of the slider 201, so as to achieve automatic lubrication. When the lead screw 203 rotates to the limit position, the end of the lead screw 203 abuts against the partition plate 208 in the middle of the slider 201, so that the partition plate 208 absorbs the impact energy of the lead screw 203 through deformation and isolates the direct contact of the lead screws 203 on both sides to avoid rigid collision.

[0053] Reference Figures 6-8The lubrication mechanism 3 includes oil tanks 301 fixed at both ends of the slider 201 and baffles 302 slidably penetrating the lower end of the oil tanks 301. The two oil tanks 301 are respectively located at the oil drain holes 210 on the top and inner bottom surfaces of the slider 201. The two oil tanks 301 are fixedly installed on the top and inner bottom surfaces of the slider 201, respectively, with their bottom ends fixed to the surface of the slider 201, ensuring that the oil outlet area at the bottom of the oil tanks 301 covers the corresponding oil drain holes 210 on the slider 201. Springs 303 are fixed at both ends of the baffle 302. The formula for calculating the elastic force of the springs 303 is F = kx, where F represents the elastic force of the springs 303, k represents the constant of the springs 303, and x represents the elastic force of the springs 303. The compression amount is such that the two ends of the second spring 303 are fixed to one side of the baffle 302 and the inner wall of the oil tank 301, respectively. The surface of the baffle 302 is symmetrically provided with through holes 304. When the baffle 302 is pushed and slid to a specific position, one of the through holes 304 can be precisely aligned with the oil leakage hole 210 on the slider 201 below it. When the baffle 302 is reset under the action of the second spring 303, the through hole 304 and the oil leakage hole 210 are misaligned, thereby controlling the connection and disconnection of the oil circuit, which is used to transport the lubricating oil inside the oil tank 301 to the oil leakage hole 210. The lower end of the oil tank 301 is provided with a sliding groove 306 on the side near the rotating block 202. One end of the baffle 302 extends through the sliding groove 306 to the outside of the oil tank 301.

[0054] When the rotating block 202 rotates, the push rod 207 or push rod 213 fixed on the outer ring of the rotating block 202 moves accordingly. When the push rod 207 or push rod 213 touches the end of the baffle 302 located outside the oil tank 301, it pushes the baffle 302 to slide laterally inside the oil tank 301. At this time, the springs 303 on both sides of the baffle 302 are in a compressed or stretched state. During the sliding process of the baffle 302, the through hole 304 on the surface of the baffle 302 is connected to the oil leakage hole 210 at the lower end of the oil tank 301 as it is displaced. At this time, the lubricating oil in the oil tank 301 is delivered to the surface of the lead screw 203 and the recesses on both sides of the slider 201 through the through hole 304, the oil leakage hole 210, the through hole 211, and the through hole 214 in sequence, thereby realizing automatic lubrication.

[0055] The baffle 302, located inside the fuel tank 301, has a width consistent with the width of the inner wall of the fuel tank 301, a height greater than the height of the chute 306, and a length approximately two-thirds the length of the fuel tank 301 (e.g., ...). Figure 6 , Figure 8As shown, the side of the baffle 302 facing the slide groove 306 is tightly fitted to the inner wall of the oil tank 301, effectively preventing lubricating oil from leaking from the sliding gap. The oil leakage hole 210 on the slider 201 is located directly below the installation position of the oil tank 301. On the sliding path of the baffle 302, the oil leakage hole 210 is located between the areas covered by the center points of the two through holes 304 when they move to directly below the oil leakage hole 210. The length of the slide groove 306 is equal to the length of the baffle 302 when it moves from one through hole 304 aligned with the oil leakage hole 210. Another through hole 304 is aligned with the total stroke required for the oil leakage hole 210. One end of the through hole 304 is located outside the oil tank 301 and extends to the rotation trajectory of the push rod 207 centered on the rotating block 202. The other end of the through hole 304 is located outside the oil tank 301 and extends to the rotation trajectory of the push rod 213 centered on the rotating block 202. An oil inlet is provided at the top center of the oil tank 301. A piston 305 is movably inserted inside the oil inlet. The piston 305 is used to seal the oil inlet.

[0056] As the rotating block 202 continues to rotate, push rod 207 or push rod 213 disengages from the baffle 302, causing spring 303 to rebound and reset the baffle 302, thereby causing the through hole 304 to misalign with the oil leakage hole 210 and closing the lubrication channel.

[0057] Reference Figure 10 , Figure 11 The fixing mechanism 4 includes a fixing plate 401 and a buffer pad 405 fixed to the lower end of the fixing plate 401. The fixing plates 401 are fixed to the inner walls of both ends of the buffer frame 1 in a pairwise opposing manner, corresponding to the stroke limit position of the slider 201, and are used to limit the sliding stroke of the slider 201. The buffer pad 405 is made of nitrile rubber, which has good elasticity and flexibility, making it easy to deform quickly and return to its original shape when impacted by the slider 201, effectively absorbing energy. It also has excellent oil resistance, making it easy to maintain stable performance in oily environments. At the same time, the material also has good wear resistance and heat resistance, and is used to absorb the energy generated by the slider 201 hitting the inner walls of the buffer frame 1 when the slider 201 slides to the limit distance. The fixing plate 401 has symmetrical slots 404 on the side near the slide rail 6. The slots 404 are L-shaped (e.g., Figure 11 As shown), insert blocks 402 are movably inserted into the interior of the two slots 404. The shape of the part of the insert block 402 that is inserted into the slot 404 is adapted to the shape of the slot 404. One end of the insert block 402 located inside the slot 404 slides in the slot 404.

[0058] When the fixing plate 401 needs to be installed, the operator uses external force to press the two inserts 402 in opposite directions, causing the inserts 402 to slide in opposite directions along the L-shaped track of the rectangular groove 7 and the slot 404. At this time, the spring 3 403 is in a compressed state. When the inserts 402 are released, the spring 3 403 rebounds and drives the inserts 402 to reset, thereby causing the protruding part of the inserts 402 to be inserted into the slot 404.

[0059] A rectangular groove 7 is provided on the inner wall of both ends of the buffer frame 1 at the position of the slot 404 of the fixing plate 401. The rectangular groove 7 is connected to the slot 404. The ends of the two inserts 402 away from the fixing plate 401 pass through the rectangular groove 7 and slide in the rectangular groove 7. A spring 3 403 is fixed on the opposite side of the two inserts 402. The formula for calculating the elastic force of the spring 3 403 is F = kx, where F represents the elastic force of the spring 3 403, k represents the constant of the spring 3 403, and x represents the compression of the spring 3 403. The two ends of the spring 3 403 are fixed to the opposite side of the two inserts 402 respectively.

[0060] When the fixing plate 401 needs to be replaced, repeat the above operation to disengage the insert 402 from the slot 404. When the slider 201 slides along the slide rail 6 to the limit distance, the end of the slider 201 hits the buffer pad 405 fixed at the lower end of the fixing plate 401, so that the buffer pad 405 absorbs the impact energy through its own elastic deformation.

[0061] The implementation principle of the winding roller moving buffer structure in this application embodiment is as follows: When the device is in use, a wide plastic film is wrapped around the bottom of the conveyor roller 5. The tension of the wide plastic film drives the conveyor roller 5 to rotate and drives the slider 201 to slide on the slide rail 6, so that the spring 205 is compressed or stretched, thereby pushing the lead screw 203, causing the lead screw 203 to move axially and drive the rotating block 202 to rotate. The elastic deformation of the spring 205 and the axial movement of the lead screw 203 work together to achieve the buffer function. When the rotating block 202 rotates, the push rod 207 or the push rod 213 pushes the baffle 302 to slide to achieve automatic lubrication. The rotation of the conveyor roller 5 synchronously constrains the movement stroke of the buffer mechanism 2 to prevent the conveyor roller 5 from tilting. By squeezing the two inserts 402, the inserts 402 are inserted into the slots 404 to fix the fixed plate 401. When the slider 201 slides to the limit distance, the buffer pad 405 absorbs the impact energy of the slider 201.

[0062] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
