Technical Field

[0001] This utility model relates to the field of coating production equipment technology, and more specifically, to a backing fabric feeding anti-deviation device for a coating machine. Background Technology

[0002] In the coating production process, the conveying of the backing fabric from the fabric roll to the coating process is a critical starting point.

[0003] However, in actual production, the backing fabric is prone to shifting during the conveying process. Once the backing fabric shifts, the subsequent coating process will be affected by the inaccurate position of the backing fabric, resulting in uneven coating of the applied product, non-standard dimensions, and other quality problems. In severe cases, it may even lead to product scrapping and significantly increase production costs. In view of this, we propose a backing fabric feeding anti-shifting device for the coating machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a backing cloth feeding anti-deviation device for a coating machine, so as to solve the technical problem that the backing cloth is prone to deviation during the current conveying process, resulting in inaccurate positioning in subsequent coating processes.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a backing fabric feeding anti-deviation device for a coating machine, comprising a support platform, a displacement component fixedly installed on the top of the support platform, and a conveying roller assembly for conveying the backing fabric fixedly installed on the top of the displacement component.

[0006] The displacement assembly includes two guide rails fixedly installed on the top of the support platform, a support frame slidably installed between the outer walls of the two guide rails, a hydraulic cylinder located on the top of the support platform fixedly connected to one side plate wall of the support frame, and a positioning assembly for squeezing the backing fabric fixedly installed between the opposing surfaces of the support frames.

[0007] The conveying roller assembly includes a drive assembly fixedly installed on one side of the support frame. The output end of the drive assembly is fixedly connected to a fixed roller for feeding material. Limiting members that are fixedly connected to the top of the support frame are rotatably installed on the outer walls of both ends of the fixed roller.

[0008] This invention, through the sliding cooperation of two guide rails and a support frame, and the drive of a hydraulic cylinder, enables flexible adjustment of the position of the conveying roller assembly. It can accurately match the feeding requirements of backing fabrics of different specifications, ensuring that the backing fabric is always in the optimal working position of the coating machine. At the same time, the drive component in the conveying roller assembly drives the fixed roller to rotate, stably discharging the material and ensuring that the backing fabric is stable and does not shake during the conveying process, greatly improving the conveying efficiency and stability of the backing fabric.

[0009] Preferably, the positioning assembly includes two fixing members fixed to the opposing surfaces of the support frame. Each of the two fixing members has an inclined pressing member fixed at its opposing end for pressing the two ends of the backing fabric. A pressure rod that fits against the surface of the backing fabric is rotatably installed between the two pressing members.

[0010] Preferably, the extrusion member includes a fixed plate, and a limiting rod is rotatably installed between the two ends of the fixed plate. The limiting rod has a plurality of grooves on its wall.

[0011] Preferably, the fixed plate has an internal groove, a spring is fixedly installed on the side of the groove near the fixed roller, a slider that fits into the groove is fixedly connected to the end of the spring, and a support block that is rotatably connected to the pressure rod is fixedly installed on the outer end of the slider.

[0012] Preferably, the bottom of the slider is rotatably mounted with a ball bearing that fits against the side of the slide groove, and the opposing surface of the slider is constructed with an anti-sticking groove to reduce contact with the side of the slide groove.

[0013] Preferably, the fixing component includes a fixing sleeve, and a support rod that is fixedly connected to the extruder is movably installed inside the fixing sleeve. A through hole is provided on the side of the fixing sleeve that connects to the support frame, and an adjusting screw that passes through the through hole is threaded onto the plate wall of the support frame.

[0014] Preferably, the opposing sides of the inside of the fixing sleeve are each constructed with an arc-shaped resistance strip, and the opposing sides of the support rod are each constructed with a flexible resistance groove that is combined with the resistance strip.

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

[0016] 1. This utility model, through the sliding cooperation of two guide rails and support frame, and the drive of hydraulic cylinder, can realize flexible adjustment of the position of the conveying roller assembly, accurately match the feeding requirements of backing fabrics of different specifications, and ensure that the backing fabric is always in the optimal working position of the coating machine. At the same time, the drive component in the conveying roller assembly drives the fixed roller to rotate, stably feeding the material and ensuring that the backing fabric is stable and does not shake during the conveying process, which greatly improves the conveying efficiency and stability of the backing fabric.

[0017] 2. This utility model also utilizes the squeezing element and pressure rod in the positioning assembly to limit the compression of the backing fabric at both ends against the surface. The groove on the wall of the limiting rod increases the friction between the backing fabric and the backing fabric, facilitating rotation. This prevents the backing fabric near the surface from shifting due to inertia when adjusting its position, especially when the backing fabric thickness is too large. The pressure rod adheres to the surface of the backing fabric, further limiting the stability of the backing fabric's position on the surface, achieving dual positioning. This effectively ensures the accuracy of backing fabric feeding, avoids uneven coating caused by offset, and improves the quality of the applied product. Attached Figure Description

[0027] like Figures 1 to 8As shown, this utility model relates to a backing fabric feeding anti-deviation device for a coating machine, including a support platform 1. A displacement component 2 is fixedly installed on the top of the support platform 1. A conveying roller assembly 3 for conveying the backing fabric is fixedly installed on the top of the displacement component 2. The displacement component 2 includes two guide rails 201 fixedly installed on the top of the support platform 1. A support frame 202 is slidably installed between the outer walls of the two guide rails 201. A hydraulic cylinder 203 located on the top of the support platform 1 is fixedly connected to one side wall of the support frame 202. A positioning component 4 for squeezing the backing fabric is fixedly installed between the opposing surfaces of the support frames 202. The operation of the hydraulic cylinder 203 can push or pull the support frame 202 to move along the surface of the guide rails 201, and can be adjusted to a suitable position in time when deviation occurs.

[0028] The conveying roller assembly 3 includes a drive assembly 301 fixedly installed on one side of the support frame 202. The output end of the drive assembly 301 is fixedly connected to a fixed roller 302 for feeding. Both ends of the fixed roller 302 are rotatably mounted on the outer walls of the fixed roller 302 and fixedly connected to the top of the support frame 202. Through cooperation, the backing fabric being wound can be stably conveyed and moved, maintaining the smoothness of the conveying operation.

[0029] In an embodiment of this utility model, the positioning component 4 includes two fixing members 5 fixed to the opposing surfaces of the support frame 202. The opposing ends of the two fixing members 5 are inclinedly fixed with pressing members 6 for pressing the two ends of the backing fabric. A pressure rod 7 that fits against the surface of the backing fabric is rotatably installed between the two pressing members 6. The pressing members 6 can limit the position of the two ends of the backing fabric, thereby limiting the width of the two ends and making it less likely for the backing fabric on the surface to shift position. The pressure rod 7 can further improve the stability of the position of the backing fabric on the surface.

[0030] In an embodiment of this utility model, the extrusion member 6 includes a fixing plate 601, and a limiting rod 602 is rotatably installed between the two ends of the fixing plate 601. The limiting rod 602 has a plurality of grooves 603 on its rod wall. The rotatable design allows it to rotate when subjected to a certain frictional force. The grooves 603 can increase the frictional force, making it easier to achieve the effect of rotating synchronously with the backing fabric.

[0031] In an embodiment of this utility model, the internal structure of the fixing plate 601 includes a groove 604. A spring 605 is fixedly installed on the side of the groove 604 near the fixing roller 302. A slider 606 that fits into the groove 604 is fixedly connected to the end of the spring 605. A support block 607 that is rotatably connected to the pressure rod 7 is fixedly installed on the outer end of the slider 606. The slider 606 can automatically reset after sliding due to the limiting effect of the spring 605, so that it can maintain a state of fit with the pressure rod 7 during the backing fabric feeding process.

[0032] In an embodiment of this utility model, a ball bearing 608 is rotatably mounted on the bottom of the slider 606 and fits against the side of the slide groove 604. The opposing surface of the slider 606 is constructed with an anti-sticking groove 609 to reduce contact with the side of the slide groove 604. The design of both can reduce the frictional force of the slider 606 displacement, making it easier for the pressure rod 7 to move synchronously as the thickness of the backing fabric decreases.

[0033] In an embodiment of this utility model, the fixing member 5 includes a fixing sleeve 501. A support rod 502, which is fixedly connected to the extrusion member 6, is movably installed inside the fixing sleeve 501. A through hole 503 is provided on the side of the fixing sleeve 501 that is connected to the support frame 202. An adjusting screw 8 that passes through the through hole 503 is threadedly connected to the plate wall of the support frame 202. By adjusting the screw 8 through the through hole 503 and abutting against the support rod 502, the position of the end of the support rod 502 can be adjusted under the threaded engagement, so that the limiting rods 602 on both sides can abut against the end faces of the backing fabrics of different sizes.

[0034] In the embodiments of this utility model, an arc-shaped resistance strip 504 is constructed on one side of the facing surface inside the fixed sleeve 501, and a flexible resistance groove 505 that is combined with the resistance strip 504 is constructed on the opposite side of the support rod 502; by increasing the resistance between the support rod 502 and the fixed sleeve 501, the position of the extrusion part 6 is prevented from shifting due to vibration and other factors during operation.

[0035] Working Principle: This embodiment provides a backing fabric feeding anti-deviation device for a coating machine. After the device is started, the drive assembly 301 begins to work, outputting power to drive the fixed roller 302 to rotate. The backing fabric wound on the fixed roller 302 begins to be unloaded and conveyed out under its rotation. The limiting parts 303 on the outer walls at both ends of the fixed roller 302 provide support and limit the fixed roller 302, ensuring that the fixed roller 302 remains stable during rotation and avoiding unstable backing fabric conveying due to shaking. An edge detection sensor can be set at the conveying position (this is a common technical structure in this field and will not be described in detail here). When it is necessary to adjust the conveying position or direction of the backing fabric, the hydraulic cylinder 203 comes into play. The piston rod of the hydraulic cylinder 203 extends and retracts, pushing the support frame 202 to slide along the outer walls of the two guide rails 201. By controlling the extension and retraction of the hydraulic cylinder 203, the position of the support frame 202 can be precisely adjusted, thereby adjusting the overall position of the fixed roller 302 and the backing fabric, so that the backing fabric is in a suitable starting position for conveying, to adapt to different production needs and working scenarios. During the conveying process of the backing fabric, the positioning component 4 is responsible for preventing the backing fabric from shifting. The two fixing parts 5 fixed to the opposing surfaces of the support frame 202 serve to connect and support the extrusion component 6. The limiting rod 602 rotatably mounted on the fixing plate 601 in the extrusion component 6 has several grooves 603 on its rod wall that contact the two ends of the backing fabric. The grooves 603 increase the friction between the backing fabric and the rod, achieving a self-rotating effect under a certain force, which can effectively limit the movement of the backing fabric in the width direction and prevent the backing fabric from shifting to both sides. At the same time, the elastic support structure composed of components such as the sliding groove 604, spring 605, slider 606, and support block 607 inside the fixing plate 601 allows the pressure rod 7 to fit tightly against the surface of the backing fabric. When the backing fabric experiences fluctuations or thickness changes during transport, the spring 605 can extend or retract according to the actual situation, causing the slider 606 to slide within the groove 604. The ball bearings 608 at the bottom of the slider 606 reduce friction during sliding, ensuring the slider 606 moves flexibly. This allows the pressure rod 7 to remain in contact with the backing fabric surface, providing compression and guidance, further ensuring stable transport of the backing fabric along the predetermined direction. The fixing sleeve 501, support rod 502, through hole 503, and adjusting screw 8 in the fixing component 5 work together to adjust the position of the extruder 6. By turning the adjusting screw 8 through the through hole 503, the threaded connection depth between the adjusting screw 8 and the support frame 202 is changed, thereby pushing the support rod 502 to move within the fixing sleeve 501, thus adjusting the position of the extruder 6. In this way, the spacing and position of the extruder 6 can be flexibly adjusted according to the different widths of the backing fabric or actual production needs, ensuring that the extruder 6 can effectively compress both ends of the backing fabric, achieving a good anti-deviation effect.In addition, the resistance strip 504 inside the fixed sleeve 501 is combined with the flexible resistance groove 505 on the support rod 502. After the position of the extruder 6 is adjusted, the resistance between the support rod 502 and the fixed sleeve 501 can be increased to prevent the extruder 6 from shifting position due to vibration and other factors during operation, thus ensuring the stability of the anti-shift device.

[0036] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
