Abstract
Description
Technical Field
[0001] This utility model relates to a coating machine roller passing device with integrated dust removal, specifically a coating machine roller passing device with integrated dust removal, belonging to the field of coating machine technology. Background Technology
[0002] The overroller unit is a crucial component of a coating machine, primarily used to support and convey the substrate, ensuring stable tension and trajectory during coating. This unit typically consists of multiple rollers, including a drive roller, a driven roller, and a tension roller. These rollers are mounted on the frame via bearings and rotated by a drive system. During operation, the substrate is drawn from the unwinding unit, guided and tensioned by a series of overrollers, and then enters the coating area for coating. Afterward, it is conveyed to the rewinding unit via the overrollers. Parameters such as the surface quality, parallelism, and rotational speed of the overrollers significantly impact the coating effect and production quality; therefore, these parameters must be strictly controlled during design and manufacturing to ensure the stability and reliability of the overroller unit.
[0003] The prior art patent application number is 202121636576.9, entitled "A Roller Cleaning Device for Continuous Sheet Production". The roller cleaning device is fixed on the roller support plate, and each roller corresponds to a set of roller cleaning devices. The roller cleaning device includes a fixed bracket and a cleaning groove fixed on the bracket. The two ends of the fixed bracket are respectively installed on the roller support plates on both sides. The cleaning groove is an arc-shaped structure that matches the curvature of the roller. The cleaning groove contacts the roller and achieves cleaning under the rotation of the roller.
[0004] The adjusting bolt lacks a necessary locking mechanism. After the cleaning plate contacts the roller surface, the adjusting bolt will rotate due to the pressure applied by the roller surface. This prevents the cleaning plate from maintaining a stable and continuous contact with the roller surface, making it difficult to achieve the desired cleaning effect. Furthermore, the adjusting bolt is exposed, making it highly susceptible to dust and impurities from the external environment. This not only hinders the rotation of the adjusting bolt, affecting adjustment accuracy, but also accelerates the wear of the adjusting bolt and its surrounding components, shortening the service life of the roller conveyor and increasing equipment maintenance costs and downtime for repairs. Therefore, a new technical solution is needed to address this issue. Utility Model Content
[0005] The purpose of this utility model is to provide an integrated dust removal coating machine roller device to solve the above-mentioned problems. In this way, the adjusting bolt in the prior art lacks the necessary locking mechanism. After the cleaning plate comes into contact with the roller surface, the adjusting bolt will rotate due to the pressure applied by the roller surface. This causes the cleaning plate to be unable to continuously and stably adhere to the roller surface, and the adjusting bolt is exposed. Dust and impurities in the external environment can easily adhere to it, which may not only cause the adjusting bolt to be obstructed from rotating, but also affect the adjustment accuracy.
[0006] This utility model is achieved through the following technical solution: a coating machine roller device with integrated dust removal.
[0007] The device includes a fixed bracket, on one side of which two limiting rods are slidably connected. One end of each limiting rod passes through the fixed bracket and extends to the other side of the fixed bracket, and a cleaning plate is fixedly connected to one end of each limiting rod. A rotating rod is rotatably connected to one side of the fixed bracket. An annular groove is formed on the outer side of the rotating rod, and the annular grooves are arranged sequentially. The limiting rods provide a stable sliding guide for the cleaning plate, ensuring that the cleaning plate maintains a straight trajectory during movement and avoiding uneven contact with the roller surface due to lateral offset.
[0008] Preferably, one end of the rotating rod passes through the fixed bracket and extends to the other side of the fixed bracket, and one end of the rotating rod is fixedly connected to a threaded rod. The annular groove cooperates with the subsequent V-shaped locking block to provide a reliable positioning point for the screw locking mechanism, ensuring stable locking can be achieved in different adjustment positions.
[0009] Preferably, a threaded sleeve is screwed onto the outer side of the threaded rod, and the threaded sleeve is fixedly connected to the cleaning plate. The cooperation between the threaded rod and the threaded sleeve forms a helical transmission pair, which converts the rotational motion of the rotating rod into the linear motion of the cleaning plate, thereby achieving precise position adjustment.
[0010] Preferably, a sealing sleeve rod is rotatably connected to one side of the fixed bracket. The sealing sleeve rod is located outside the threaded rod, and one end of the sealing sleeve rod extends into the interior of the threaded sleeve. The sealing sleeve rod and the threaded sleeve form a closed space, which effectively prevents dust and impurities from entering the threaded transmission pair, extends the service life, and reduces the maintenance frequency.
[0011] A mounting bracket is fixedly connected to one side of the fixed bracket, and a friction rod is fixedly connected to the inner side of the mounting bracket. The friction rod serves as a guide shaft, providing a precise trajectory for the sliding of the friction plate and the V-shaped locking block, thus ensuring the stability of the locking action.
[0012] Preferably, two compression springs are sleeved on the outer side of the friction rod, and two friction plates are slidably connected to the outer side of the friction rod. The compression springs provide continuous axial pressure, causing the friction plates to drive the V-shaped locking block to tightly fit into the annular groove, thereby enhancing the locking force.
[0013] Preferably, a V-shaped locking block is fixedly connected to one side of the friction plate, and a rubber damping pad is adhered to one side of the V-shaped locking block. The rubber damping pad is in contact with the annular groove. The high coefficient of friction and elastic deformation capacity of the rubber damping pad significantly enhance the locking torque and absorb vibration energy to prevent loosening.
[0014] This utility model provides an integrated dust removal device for the rollers of a coating machine, which has the following beneficial effects:
[0015] 1. This integrated dust removal coating machine roller device, through a screw sealing mechanism, can effectively isolate the adjusting screw from the external environment, greatly reducing the chance of dust and impurities coming into contact with the screw. It can prevent dust and other foreign objects from entering the screw transmission components, prevent screw rotation jamming caused by impurity accumulation, ensure smooth and unobstructed adjustment operation, and effectively improve adjustment accuracy.
[0016] 2. The integrated dust removal coating machine roller device uses a screw locking mechanism. When the cleaning plate contacts the roller surface, the screw locking mechanism can quickly lock the adjusting bolt, so that it no longer rotates under the pressure of the roller surface. This ensures that the cleaning plate always keeps in close contact with the roller surface, guaranteeing the continuity and stability of the cleaning effect. Attached Figure Description

[0028] This utility model provides a coating machine roller passing device with integrated dust removal.
[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a fixed bracket 1, with two limiting rods 101 slidably connected to one side of the fixed bracket 1. One end of the limiting rod 101 passes through the fixed bracket 1 and extends to the other side of the fixed bracket 1, and a cleaning plate 102 is fixedly connected to one end of the limiting rod 101. A rotating rod 2 is rotatably connected to one side of the fixed bracket 1. An annular groove 201 is opened on the outer side of the rotating rod 2, and the annular grooves 201 are arranged in sequence.
[0030] Please refer to it again. Figure 1 , Figure 2 and Figure 3 One end of the rotating rod 2 passes through the fixed bracket 1 and extends to the other side of the fixed bracket 1. A threaded rod 3 is fixedly connected to one end of the rotating rod 2. A threaded sleeve 301 is screwed onto the outside of the threaded rod 3. The threaded sleeve 301 is fixedly connected to the cleaning plate 102. A sealing sleeve rod 4 is rotatably connected to one side of the fixed bracket 1. The sealing sleeve rod 4 is located outside the threaded rod 3. One end of the sealing sleeve rod 4 extends into the inside of the threaded sleeve 301.
[0031] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A mounting bracket 5 is fixedly connected to one side of the fixed bracket 1. A friction rod 501 is fixedly connected to the inner side of the mounting bracket 5. Two compression springs 502 are sleeved on the outer side of the friction rod 501. Two friction plates 503 are slidably connected to the outer side of the friction rod 501. A V-shaped locking block 6 is fixedly connected to one side of the friction plate 503. A rubber damping pad 601 is glued to one side of the V-shaped locking block 6. The rubber damping pad 601 is in contact with the annular groove 201.
[0032] When the device is running, the rotating rod 2 drives the threaded rod 3 to rotate synchronously. Driven by the threaded rod 3, the threaded sleeve 301 moves axially, thereby moving the cleaning plate 102 closer to or further away from the roller surface, thus adjusting the cleaning position. During this process, the sealing sleeve rod 4 is fitted onto the outside of the threaded rod 3, with one end extending into the interior of the threaded sleeve 301, forming a relatively enclosed space. This structural design effectively prevents external dust and impurities from entering the threaded mating area between the threaded rod 3 and the threaded sleeve 301, preventing thread wear or jamming caused by impurity accumulation, and ensuring the smoothness and stability of the adjustment action.
[0033] The compression spring 502 applies pressure to the V-shaped locking block 6 via the friction plate 503, causing the rubber damping pad 601 to fit tightly against the groove wall of the annular groove 201. Because the rubber damping pad 601 has a high coefficient of friction, it generates sufficient frictional torque to effectively prevent the rotation of the rotating rod 2. When the cleaning plate 102 contacts the roller surface and is subjected to roller surface pressure, this frictional torque prevents the rotating rod 2 from rotating due to force, thus ensuring that the threaded rod 3 will not cause the threaded sleeve 301 to move due to accidental rotation of the rotating rod 2, guaranteeing that the cleaning plate 102 always maintains a stable contact with the roller surface. Furthermore, the structural design of the V-shaped locking block 6 allows it to adapt to the shape of the annular groove 201 when subjected to the pressure of the compression spring 502, further enhancing the locking effect. Simultaneously, the elastic properties of the rubber damping pad 601 can absorb vibrations transmitted from the roller surface, reducing locking loosening caused by vibration and improving the reliability and stability of the entire mechanism.
[0034] Working Principle: When the device is running, the rotating rod 2 drives the threaded rod 3 to rotate synchronously. Driven by the threaded rod 3, the threaded sleeve 301 moves axially, thereby moving the cleaning plate 102 closer to or further away from the roller surface, thus adjusting the cleaning position. During this process, the sealing sleeve rod 4 is fitted onto the outside of the threaded rod 3, with one end extending into the interior of the threaded sleeve 301, forming a relatively enclosed space. This structural design effectively prevents external dust and impurities from entering the threaded mating area between the threaded rod 3 and the threaded sleeve 301, preventing thread wear or jamming caused by impurity accumulation, ensuring the smoothness and stability of the adjustment action. The compression spring 502 applies pressure to the V-shaped locking block 6 through the friction plate 503, causing the rubber damping pad 601 to tightly adhere to the groove wall of the annular groove 201. Because the rubber damping pad 601 has a large coefficient of friction, it can generate sufficient frictional torque to effectively prevent the rotation of the rotating rod 2. When the cleaning plate 102 contacts the roller surface and is subjected to roller surface pressure, the frictional torque prevents the rotating rod 2 from rotating due to the force, thereby ensuring that the threaded rod 3 will not cause the threaded sleeve 301 to move due to the accidental rotation of the rotating rod 2, ensuring that the cleaning plate 102 always maintains a stable contact with the roller surface. In addition, the structural design of the V-shaped locking block 6 allows it to adapt to the shape of the annular groove 201 when subjected to the pressure of the compression spring 502, further enhancing the locking effect. At the same time, the elastic properties of the rubber damping pad 601 can also absorb the vibration transmitted by the roller surface, reduce the phenomenon of locking loosening caused by vibration, and improve the reliability and stability of the entire mechanism.
