Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to the addition of left and right gap adjustment to the coating pressure roller. Background Technology

[0002] Coating rollers are key functional components in coating equipment used to apply pressure to the substrate and coating to ensure uniform coating, flat substrate, and enhanced coating adhesion.

[0003] When conventional gravure coating machines assist in the adhesive coating process on fabrics, the coating process is affected by many factors such as material thickness, tension, surface characteristics, adhesive viscosity, solid content, and machine speed. The positions of the two pressure rollers of existing gravure coating machines can only be adjusted up and down. This single up and down adjustment cannot effectively compensate for the differences under different coating conditions, which may lead to uneven coating, missed coating, or over-coating, ultimately affecting product quality and coating effect. Utility Model Content

[0004] The technical problem this invention aims to solve is that when conventional gravure coating machines assist in the adhesive coating process on fabrics, the two pressure rollers of existing gravure coating machines can only be adjusted up and down due to the influence of multiple factors such as material thickness, tension, surface characteristics, adhesive viscosity, solid content, and machine speed during the coating process. This single up-and-down adjustment cannot effectively compensate for the differences under different coating conditions, which may lead to uneven coating, missed coating, or over-coating, ultimately affecting product quality and coating effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a coating machine with adjustable left and right gap of pressure rollers, including a micro-gravure coating machine and two supports. Several transition rollers are rotatably installed on the inner wall of the micro-gravure coating machine. A glue tank is fixedly installed on the inner wall of the micro-gravure coating machine. A micro-gravure roller is rotatably installed on the inner wall of the glue tank. A pressure roller is rotatably installed on the inner wall of the supports. An adjustment device is provided between one side of the supports and the inner wall of the micro-gravure coating machine. The adjustment device can adjust the height of the two supports and the pressure roller, as well as the distance between the two pressure rollers.

[0006] Preferably, the adjusting device includes two first rectangular rods, with first grooves symmetrically formed on both sides of the inner wall of the microgravure coating machine, wherein the two ends of the first rectangular rods are slidably installed in the inner wall of the first grooves; two first threaded rods, wherein the outer surface of the first threaded rods is helically inserted into the inner wall of the first rectangular rods, and one end is rotatably installed on one side of the support; two second rectangular rods, wherein the two ends of the second rectangular rods are fixedly installed on both sides of the inner wall of the microgravure coating machine; two second threaded rods, wherein the outer surface of the second threaded rods is helically inserted into the inner wall of the second rectangular rods; two push frames, wherein one side of the push frame is rotatably installed on one side of one end of the second threaded rod; a plurality of first telescopic rods, wherein one end of the first telescopic rod is fixedly installed on one side of the support; a slide, wherein one side of the slide is fixedly installed on one side of the first telescopic rod, with second grooves symmetrically formed on both sides of the inner wall of the microgravure coating machine, wherein the two ends of the slide are slidably installed in the inner walls of two opposite second grooves; and a plurality of connecting rods, wherein the two ends of the connecting rods are rotatably installed in the inner wall of one end of the push frame and the inner wall of one end of the slide.

[0007] The effects achieved by the above components are as follows: By setting the adjustment device, when using a micro-gravure coating machine to coat fabric, the fabric passes over one of the transition rollers, then is placed below the two pressure rollers and above the micro-gravure roller, and finally passes under the other transition roller. At this point, according to actual processing needs, the first threaded rod can be manually screwed onto the first rectangular rod a certain number of times, driving the support and pressure roller to move downwards. This causes the first telescopic rod to stretch, pressing and straightening the fabric on both sides of the micro-gravure roller. This ensures that one side of the fabric is tightly attached to one side of the micro-gravure roller, improving the coating effect. Then, according to needs, the second threaded rod can be screwed onto the second rectangular rod a certain number of times, driving the pusher to move downwards. The connecting rod will then push the slide to one end in the second slide groove. Under the connection of the first telescopic rod, the support and pressure roller will move with the slide to adjust the distance between the two supports and the pressure roller, ensuring the uniformity of coating, avoiding missed or over-coating, and improving the accuracy, flexibility, and product quality of the coating process.

[0008] Preferably, bearings are fixedly installed on both ends of the connecting rod, and the outer rings of several bearings are fixedly installed on both sides of the inner wall of the push frame and the inner wall of the slide.

[0009] The effect achieved by the above components is that by setting bearings, the rotational wear between the connecting rod and the pusher and the slide can be reduced, and the pusher can push the slide in the second slide groove for adjustment.

[0010] Preferably, the longitudinal section of the second slide groove is T-shaped, and the longitudinal sections at both ends of the slide are T-shaped.

[0011] The effect achieved by the above components is that by making both ends of the second slide groove and the slide carriage T-shaped, the slide carriage can be more stable when sliding in the second slide groove and is less prone to shaking.

[0012] Preferably, a limiting mechanism is provided between the first threaded rod and the first rectangular rod and the second threaded rod and the second rectangular rod. The limiting mechanism includes a locking rod, with a plurality of locking grooves opened on the outer surface of one end of the first threaded rod and the second threaded rod, wherein one side of the locking rod is inserted into the inner wall of the locking groove, a second telescopic rod is fixedly installed on one side of the first rectangular rod and the second rectangular rod, and a locking hole frame is rotatably installed on one side of the first threaded rod and the second threaded rod, wherein one side of the locking hole frame is fixedly installed on one side of the second telescopic rod, and one end of the locking rod is slidably installed in the inner wall of the locking hole frame; and two springs, wherein the two ends of the springs are respectively fixedly installed on one side of the locking rod and one side of the locking hole frame.

[0013] The effect achieved by the above components is as follows: By setting a limiting mechanism, when adjusting the first and second threaded rods, the locking rod can be pulled to one end to a certain position in the locking frame, causing the spring to be stretched. Then, the first and second threaded rods are adjusted. During the adjustment process, the locking frame will move downward or upward, and the second telescopic rod will contract and stretch accordingly. After adjustment, the locking rod can be released, allowing it to be locked into the corresponding slot under the reset action of the spring. This limits and fixes the adjusted first and second threaded rods, making it less prone to self-rotation and loosening when the micro-coating machine is in use, thus improving the stability of the adjustment.

[0014] Preferably, the limiting mechanism further includes several telescopic sleeves, wherein the inner wall of the telescopic sleeve is fitted onto the outer surface of the spring, and both ends are respectively fixedly installed on one side of the clamping rod and one side of the clamping hole frame.

[0015] The effect achieved by the above components is that by setting up a telescopic sleeve, the spring can be completely covered, limiting its movement without affecting its use. This prevents the spring from bending and being damaged, and also prevents external dust and impurities from getting stuck in the inner wall of the spring and affecting its use.

[0016] Preferably, the cross-section of the lever is T-shaped.

[0017] The effect achieved by the above components is that by setting the lever in a T-shape, the contact area at one end can be increased, making it easier to pull it manually.

[0018] The beneficial effects of this utility model are: By setting an adjustment device, when using a micro-gravure coating machine to coat fabric, the fabric is passed over one of the transition rollers, then placed below the two pressure rollers and above the micro-gravure roller, and finally passed under the other transition roller. At this point, according to actual processing needs, the first threaded rod can be manually screwed onto the first rectangular rod a certain number of times, causing the support and pressure roller to move downwards. This stretches the first telescopic rod, pressing and straightening the fabric on both sides of the micro-gravure roller, ensuring one side of the fabric is tightly against the side of the roller, improving the coating effect. Then, according to requirements, the second threaded rod can be screwed onto the second rectangular rod a certain number of times, causing the pusher to move downwards. The connecting rod then pushes the slide carriage to one end in the second slide groove. Connected by the first telescopic rod, the support and pressure roller move with the slide carriage, adjusting the distance between the two supports and the pressure roller to ensure coating uniformity, avoid missed or over-coating, and improve the accuracy, flexibility, and product quality of the coating process.

[0025] Figure 1-5 The coating roller shown is equipped with left and right gap adjustment, including a gravure coating machine 1 and two supports 3. Several transition rollers 5 are rotatably installed on the inner wall of the gravure coating machine 1. A glue tank 6 is fixedly installed on the inner wall of the gravure coating machine 1. A gravure roller 7 is rotatably installed on the inner wall of the glue tank 6. A pressure roller 4 is rotatably installed on the inner wall of the supports 3. An adjustment device 2 is provided between one side of the supports 3 and the inner wall of the gravure coating machine 1. The adjustment device 2 can adjust the height of the two supports 3 and the pressure roller 4, as well as the distance between the two pressure rollers 4.

[0026] Figure 1-5The adjustment device 2 shown includes two first rectangular rods 22, and two first sliding grooves 21 are symmetrically provided on both sides of the inner wall of the microgravure coating machine 1. The two ends of the first rectangular rods 22 are slidably installed in the inner wall of the first sliding grooves 21, respectively; two first threaded rods 23, wherein the outer surface of the first threaded rods 23 is helically inserted into the inner wall of the first rectangular rods 22, and one end is rotatably installed on one side of the bracket 3; two second rectangular rods 24, wherein the two ends of the second rectangular rods 24 are fixedly installed on both sides of the inner wall of the microgravure coating machine 1, respectively; and two second threaded rods 25, wherein the outer surface of the second threaded rods 25 is helically inserted into the second rectangular rods 24. The inner wall of the micro-coating machine 1 contains: two pushers 26, one side of which is rotatably mounted on one end of the second threaded rod 25; several first telescopic rods 29, one end of which is fixedly mounted on one side of the bracket 3; a slide 28, one side of which is fixedly mounted on one side of the first telescopic rod 29; two symmetrical second slide grooves 212 are provided on both sides of the inner wall of the micro-coating machine 1, and the two ends of the slide 28 are slidably mounted in the inner walls of the two opposite second slide grooves 212; and several connecting rods 27, the two ends of which are rotatably mounted in the inner wall of one end of the pusher 26 and the inner wall of one end of the slide 28. By setting the adjustment device 2, when using the micro-grooving coating machine 1 to coat the fabric, the fabric will pass over one of the transition rollers 5, then be placed below the two pressure rollers 4 and above the micro-grooving roller 7, and finally pass under the other transition roller 5. At this time, according to the actual processing requirements, the first threaded rod 23 can be manually screwed on the first rectangular rod 22 a certain number of turns, which will drive the bracket 3 and the pressure roller 4 to move downward. Therefore, the first telescopic rod 29 can be stretched to press and straighten the fabric on both sides of the micro-grooving roller 7. In this way, one side of the fabric will be tightened. The adhesive is applied to one side of the micro-concave roller 7 to improve the coating effect. Then, according to the requirements, the second threaded rod 25 is screwed on the second rectangular rod 24 to a certain number of turns, which drives the pusher 26 to move downward. The connecting rod 27 will push the slide 28 to move to one end in the second slide groove 212. Under the connection of the first telescopic rod 29, the support 3 and the pressure roller 4 will move with the movement of the slide 28 to adjust the distance between the two supports 3 and the pressure roller 4 to ensure the uniformity of coating, avoid missed coating or over-coating, and improve the accuracy and flexibility of coating processing as well as product quality.

[0027] Figure 1-5Bearings 211 are fixedly installed on both ends of the connecting rod 27 shown. The outer rings of several bearings 211 are fixedly installed on both sides of the inner wall of the pusher 26 and the inner wall of the slide 28. By setting the bearings 211, the rotational wear between the connecting rod 27 and the pusher 26 and the slide 28 can be reduced, making it easier for the pusher to push and adjust the slide 28 in the second slide groove 212. The longitudinal section of the second slide groove 212 is T-shaped, and the longitudinal sections at both ends of the slide 28 are also T-shaped. By making both the second slide groove 212 and the ends of the slide 28 T-shaped, the slide 28 can slide more stably in the second slide groove 212 and is less prone to shaking.

[0028] Figure 1-5 Limiting mechanisms 210 are provided between the first threaded rod 23 and the first rectangular rod 22 and the second threaded rod 25 and the second rectangular rod 24. The limiting mechanism 210 includes a locking rod 2104. Several locking slots 2101 are opened on the outer surface of one end of the first threaded rod 23 and the second threaded rod 25. One side of the locking rod 2104 is inserted into the inner wall of the locking slot 2101. A second telescopic rod 2102 is fixedly installed on one side of the first rectangular rod 22 and the second rectangular rod 24. A locking bracket 2103 is rotatably installed on one side of the first threaded rod 23 and the second threaded rod 25. One side of the locking bracket 2103 is fixedly installed on one side of the second telescopic rod 2102, and one end of the locking rod 2104 is slidably installed in the inner wall of the locking bracket 2103. Two springs 2105 are provided, with the two ends of the springs 2105 fixedly installed on one side of the locking rod 2104 and one side of the locking bracket 2103, respectively. By setting a limiting mechanism 210, when adjusting the first threaded rod 23 and the second threaded rod 25, the locking rod 2104 can be pulled to one end in the locking frame 2103 to a certain position, causing the spring 2105 to be stretched open. Then, the first threaded rod 23 and the second threaded rod 25 are adjusted. During the adjustment process, the locking frame 2103 will move downward or upward, and the second telescopic rod 2102 will contract and stretch accordingly. After the adjustment is completed, the locking rod 2104 can be released, so that it can be locked into the corresponding locking groove 2101 under the reset action of the spring 2105. The adjusted first threaded rod 23 and the second threaded rod 25 are limited and fixed, so that the first threaded rod 23 and the second threaded rod 25 are not easy to rotate and loosen when the micro-coating machine 1 is in use, thus improving the stability of the adjustment.

[0029] Figure 1-5The limiting mechanism 210 shown also includes several telescopic sleeves 2106, the inner wall of which is fitted onto the outer surface of the spring 2105, and both ends are fixedly installed on one side of the clamping rod 2104 and one side of the clamping hole bracket 2103, respectively. By setting the telescopic sleeves 2106, the spring 2105 can be completely covered, limiting its movement without affecting its use. This prevents the spring 2105 from bending and being damaged, and also prevents external dust and impurities from getting stuck in the inner wall of the spring 2105 and affecting its use. The clamping rod 2104 has a T-shaped cross-section. By setting the clamping rod 2104 in a T-shape, the contact area at one end can be increased, making it easier to pull manually.

[0030] Working principle: When using the micro-gravure coating machine 1 to coat fabric, the fabric is passed over one of the transition rollers 5, then placed below the two pressure rollers 4 and above the micro-gravure roller 7, and finally passed under the other transition roller 5. At this point, according to actual processing requirements, the first threaded rod 23 can be manually screwed onto the first rectangular rod 22 a certain number of turns, causing the bracket 3 and pressure rollers 4 to move downwards. This stretches the first telescopic rod 29, pressing and straightening the fabric on both sides of the micro-gravure roller 7, so that one side of the fabric adheres tightly to the micro-gravure roller 7. On one side of the concave roller 7, the coating effect is improved. Then, according to the requirements, the second threaded rod 25 is screwed on the second rectangular rod 24 to a certain number of turns, which drives the pusher 26 to move downward. The connecting rod 27 will push the slide 28 to move to one end in the second slide groove 212. Under the connection of the first telescopic rod 29, the bracket 3 and the pressure roller 4 will move with the movement of the slide 28 to adjust the distance between the two brackets 3 and the pressure roller 4 to ensure the uniformity of coating, avoid missed coating or over-coating, and improve the accuracy and flexibility of coating processing as well as product quality.

[0031] When adjusting the first threaded rod 23 and the second threaded rod 25, the locking rod 2104 can be pulled to one end in the locking frame 2103 to a certain position, causing the spring 2105 to be stretched open. Then, the first threaded rod 23 and the second threaded rod 25 can be adjusted. During the adjustment process, the locking frame 2103 will move downward or upward, and the second telescopic rod 2102 will contract and stretch accordingly. After the adjustment is completed, the locking rod 2104 can be released, allowing it to be locked into the corresponding locking slot 2101 under the reset action of the spring 2105. This limits and fixes the adjusted first threaded rod 23 and the second threaded rod 25, making it less likely for the first threaded rod 23 and the second threaded rod 25 to loosen due to self-rotation when the micro-coating machine 1 is in use, thus improving the stability of the adjustment.
