Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machines, in particular to a fixing device for NIP wheels of a cleaning machine. BACKGROUND

[0002] A liquid crystal glass cleaning machine is a key equipment in the manufacturing process of liquid crystal display panels. Its core function is to efficiently and finely remove various contaminants such as oil stains, dust, fingerprints, etc. attached to the surface of the liquid crystal glass to ensure that the liquid crystal glass meets extremely high cleanliness standards, which is crucial for improving the quality and performance of liquid crystal display products. The cleaning machine is provided with a conveying device for conveying the liquid crystal glass.

[0003] In a conventional conveying device, the conveying device is composed of an upper NIP wheel and a lower NIP wheel. The lower NIP wheel is composed of two NIP wheels connected by a coupling. The coupling and the two NIP wheels are usually connected by a through-hole bolt locking or a side-hugging locking method, and a bearing is used to support the connection. However, under the condition of long-term load operation, this structure faces the risk of bolt loosening and even breaking. Once the bolt loosens and eventually breaks due to fatigue or vibration, the consequences will be disastrous. The broken bolt can seriously affect the running stability of the lower NIP wheel, and thus generate abnormal impact force or friction force when in contact with the high-speed moving liquid crystal glass. This unexpected mechanical stress can easily cause batch damage to the liquid crystal glass, not only directly causing great waste of raw materials, but also forcing the production line to be interrupted, increasing the downtime and maintenance cost of the enterprise, and ultimately increasing the overall production cost. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a fixing device for NIP wheels of a cleaning machine, which solves the problem of easy loosening and breaking of the two lower NIP wheels connected by a coupling in the conveying device of the cleaning machine in the prior art.

[0005] To achieve the above-mentioned purpose / to solve the above-mentioned technical problems, the present application is implemented by using the following technical solutions:

[0006] On the one hand, the present application provides a fixing device for NIP wheels of a cleaning machine, comprising: a fixed rod and a support assembly, the fixed rod is used to connect two lower NIP wheels, the support assembly comprises: a support part, the support part has two support plates symmetrically arranged thereon, each support plate is provided with two adjusting parts symmetrically arranged thereon, the adjusting parts located on different support plates are mirror image arranged, a support wheel is rotatably arranged on each adjusting part, the adjusting part is used to adjust the position of the support wheel, the shortest distance between the two support wheels located on the same side of the support plate is less than the diameter of the fixed rod, and the fixed rod is rotatably arranged on the support wheel.

[0007] The device realizes integrated connection through the fixed rod as a component connecting two lower NIP wheels, significantly enhances the stability and durability of the connection, and effectively avoids the risk of loosening caused by long-time operation of the traditional coupling. During the operation of the cleaning machine, the lower NIP wheel bears the heavy responsibility of conveying liquid crystal glass. However, since the two ends of the lower NIP wheel are usually fixed, it often causes the fixed rod at the connection between the two lower NIP wheels to bear a large stress concentration during the conveying process. Under the condition of long-time high stress, the fixed rod is prone to fatigue damage, bending or even breaking, which causes the lower NIP wheel to fall. In order to solve this problem, the application sets a support assembly below the fixed rod, thereby effectively dispersing and relieving the force at the middle position. The support wheel supporting the fixed rod can rotate relative to the fixed rod, avoiding adding additional burden to the rotation of the lower NIP wheel.

[0008] The support wheel in the application has two pairs, and the distance can be adjusted according to the actual situation, thereby further ensuring the stability of the fixed rod. By adjusting the distance between the two pairs of support wheels, the pressure on the fixed rod can be effectively released and dispersed. When the liquid crystal glass generates a large pressure and friction force during conveying, by increasing the distance between the support wheels on both sides of the support plate, the stress borne by the fixed rod can be significantly dispersed, thereby reducing the risk of breaking of the lower NIP wheel at the middle position due to stress concentration. Ensure that the fixed rod is always in the best working condition.

[0009] In addition, since the support wheel can rotate relative to the fixed rod, by adjusting the position of the support wheel, the contact surface position of the support wheel and the fixed rod can be changed, which helps to reduce the wear of the fixed rod and prolong the service life.

[0010] Optionally, the adjusting part comprises an adjusting block and an adjusting bolt, the adjusting bolt is in threaded connection with the support plate, the adjusting block is sleeved on the adjusting bolt, and the support wheel is rotationally connected to the adjusting bolt.

[0011] The adjusting bolt is threadedly connected with the support plate, and the connection allows the adjusting bolt to move axially on the support plate, thereby adjusting the position of the support wheel. The adjusting block is sleeved on the adjusting bolt, and rotating the adjusting block can drive the adjusting nut to rotate. In addition, the adjusting block also serves to fix the support wheel, ensuring that the support wheel does not come off the adjusting bolt during rotation. The support wheel is rotatably connected to the adjusting bolt, and this connection allows the support wheel to rotate on the adjusting bolt. When the fixed rod moves with the rotation of the lower NIP wheel, the support wheel can rotate with it, thereby avoiding friction and resistance with the fixed rod. Through the cooperation of the adjusting bolt and the adjusting block, the position of the support wheel can be accurately adjusted. When it is necessary to adjust the distance between the support wheels, the adjusting block is simply rotated to drive the adjusting bolt to rotate and move axially on the support plate, thereby driving the adjusting block and the support wheel to move together. By adjusting the distance between the two pairs of support wheels, the pressure on the fixed rod can be effectively released and dispersed, thereby reducing the risk of the lower NIP wheel breaking.

[0012] Optionally, the support plate has a groove for accommodating the fixed rod, and the fixed rod is not in contact with the groove.

[0013] When the support wheel is positioned lower, the fixed rod located on the support wheel will contact the support plate. The groove on the support plate provides space for accommodating the fixed rod, allowing the fixed rod to remain in a non-contact state with the support plate when the support wheel is positioned lower, thereby avoiding friction or collision between the fixed rod and the support plate.

[0014] Optionally, the retaining device for the washing machine NIP wheel further comprises a cleaning assembly; the cleaning assembly comprises two cleaning plates arranged on the two side walls of the two support plates away from each other, the cleaning plates have arc surfaces coaxial with the fixed rods, and the arc surfaces of the cleaning plates are provided with cleaning brushes for cleaning the outer wall of the lower NIP wheel.

[0015] The cleaning plates have arc surfaces coaxial with the fixed rods, so that the cleaning plates can adapt to the profile of the lower NIP wheel, ensuring stability and accuracy during cleaning. Meanwhile, the arc surfaces are also provided with cleaning brushes made of soft and wear-resistant materials, which can effectively remove dust and impurities on the outer wall of the lower NIP wheel.

[0016] Optionally, the bottom of the cleaning plate is detachably connected with a dust collecting groove, and the middle of the cleaning plate has a through groove in communication with the dust collecting groove.

[0017] The dust collecting groove is designed to collect the dirt and residues removed by the cleaning brushes, preventing them from scattering around the equipment or re-attaching to the lower NIP wheel. The detachable connection allows users to easily install or remove the dust collecting groove as needed, thereby facilitating cleaning and maintenance work.

[0018] Optionally, two cleaning brushes are arranged on each cleaning plate, and the two cleaning brushes are arranged on the two sides of the through slot, respectively.

[0019] When the lower NIP wheel rotates, the two cleaning brushes can simultaneously brush the outer wall of the lower NIP wheel, so that dirt and residues can be completely removed. At the same time, since the cleaning brushes are arranged on the two sides of the through slot, they can effectively guide the dirt and debris through the through slot and fall into the dust collecting groove, avoiding secondary pollution during cleaning.

[0020] Optionally, the supporting wheel is made of rubber. The rubber supporting wheel has a large friction with the fixed rod, and can stably follow the rotation of the lower NIP wheel. In addition, the rubber material has excellent elasticity and wear resistance, so that the supporting wheel can still maintain stable performance and service life under long-time and high-load working conditions. At the same time, the rubber material also has good damping performance, which can effectively absorb and disperse the vibration and impact from the lower NIP wheel and the fixed rod, thereby protecting the entire device from damage.

[0021] Compared with the prior art, the device has the following beneficial effects: the device uses the fixed rod as a component connecting the two lower NIP wheels, realizes integrated connection, significantly enhances the stability and durability of the connection, and avoids the risk of loosening of the traditional shaft coupling due to long-time operation.

[0022] By arranging the supporting assembly below the fixed rod, the stress in the fixed rod is effectively dispersed and relieved. The fixed rod is prevented from being bent or even broken due to long-time operation in a high stress state, and the lower NIP wheel is prevented from falling. The supporting wheel supporting the fixed rod is rotatably connected with the fixed rod, so as to avoid adding an additional burden to the rotation of the lower NIP wheel. The position of the supporting wheel can be adjusted by the adjusting part, so as to change the position of the contact surface of the supporting wheel and the fixed rod. This not only further releases and disperses the pressure on the fixed rod, but also helps to reduce the wear of the fixed rod and prolong the service life.

[0023] In addition, the device effectively removes and collects dust and impurities on the outer wall of the lower NIP wheel by the cleaning assembly. The cleaning process is simplified, and the cleaning efficiency and performance of the device are improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present disclosure / the present application, but not all. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use.

[0034] Embodiment one

[0035] This embodiment introduces a retaining device for NIP wheel of a washing machine, referring to Figure 1 and Figure 2The fixing device for the NIP wheel of the cleaning machine in the embodiment comprises a fixed rod 100 and a support assembly 200. The fixed rod 100 is used to connect two lower NIP wheels 300. By using the fixed rod 100 as a component to connect the two lower NIP wheels 300, integrated connection is achieved, which significantly enhances the stability and durability of the connection and effectively avoids the risk of loosening caused by long-time operation of the traditional shaft coupling. It should be noted that the diameter of the fixed rod 100 should be less than or equal to the diameter of the lower NIP wheel 300, so that the liquid crystal glass can be smoothly transported through the lower NIP wheel 300. Further, the support assembly 200 comprises a support part 210, which has two symmetrical support plates 211. Each support plate 211 is provided with two symmetrical adjustment parts 220. The adjustment parts 220 on different support plates 211 are mirror images. Each adjustment part 220 is provided with a support wheel 230 rotating thereon. The adjustment part is used to adjust the position of the support wheel 230. In the embodiment, the support wheel 230 is made of rubber. The rubber support wheel 230 has a large friction with the fixed rod 100, and can stably follow the rotation of the lower NIP wheel 300. The rubber material has excellent elasticity and wear resistance, so that the support wheel 230 can still maintain stable performance and service life under long-time and high-load working conditions. At the same time, the rubber material also has good damping performance, which can effectively absorb and disperse the vibration and impact from the lower NIP wheel 300 and the fixed rod 100, thereby protecting the entire device from damage. Further, the shortest distance between the two support wheels 230 on the same side of the support plate 211 is less than the diameter of the fixed rod 100, and the fixed rod 100 is rotatably arranged on the support wheels 230. Further, the bottom of the support part 210 is provided with a support 240 for supporting the support part 210.

[0036] During the operation of the cleaning machine, the lower NIP wheel 300 bears the function of transporting liquid crystal glass. However, since the two ends of the lower NIP wheel 300 are usually fixed, the fixed rod 100 located at the connection between the two lower NIP wheels 300 often bears a large stress concentration during the transportation process. Under the condition of long-time high stress, the fixed rod 100 is prone to fatigue damage, bending or even breaking, which causes the NIP wheel to fall down. In order to solve this problem, the support assembly 200 is arranged below the fixed rod 100 in the embodiment, thereby effectively dispersing and relieving the force at the middle position. The support wheel 230 supporting the fixed rod 100 can rotate relative to the fixed rod 100, thereby avoiding adding extra burden to the rotation of the lower NIP wheel 300.

[0037] Furthermore, in this embodiment, there are two pairs of support wheels 230, and their positions can be adjusted according to actual conditions to further ensure the stability of the fixing rod 100. Adjusting the distance between the two pairs of support wheels 230 effectively releases and disperses the pressure on the fixing rod 100. When the liquid crystal glass generates significant pressure and friction during transport, increasing the distance between the support wheels 230 located on both sides of the support plate 211 significantly disperses the stress borne by the fixing rod 100, thereby reducing the risk of breakage due to stress concentration at the center of the lower NIP wheel 300. This ensures that the fixing rod 100 is always in optimal working condition.

[0038] Furthermore, since the support wheel 230 can rotate relative to the fixed rod 100 as the fixed rod 100 rotates, the position of the contact surface between the support wheel 230 and the fixed rod 100 can be changed by adjusting the position of the support wheel 230, which helps to reduce the wear of the fixed rod 100 and extend its service life.

[0039] In this embodiment, the adjusting part 220 includes an adjusting block 221 and an adjusting bolt 222. The adjusting bolt 222 is threadedly connected to the support plate 211, the adjusting block 221 is sleeved on the adjusting bolt 222, and the support wheel 230 is rotatably connected to the adjusting bolt 222. The threaded connection between the adjusting bolt 222 and the support plate 211 allows the adjusting bolt 222 to move axially on the support plate 211, thereby adjusting the position of the support wheel 230. The adjusting block 221 is sleeved on the adjusting bolt 222, and rotating the adjusting block 221 drives the adjusting nut to rotate. Furthermore, the adjusting block 221 also serves to fix the support wheel 230, ensuring that the support wheel 230 does not detach from the adjusting bolt 222 during rotation. The support wheel 230 is rotatably connected to the adjusting bolt 222, allowing the support wheel 230 to rotate on the adjusting bolt 222. When the fixed rod 100 moves with the rotation of the lower NIP wheel 300, the support wheel 230 can rotate accordingly, thus avoiding friction and resistance between it and the fixed rod 100. The position of the support wheel 230 can be precisely adjusted by adjusting the bolt 222 and the adjusting block 221. When it is necessary to adjust the distance between the support wheels 230, simply rotate the adjusting block 221, which in turn rotates the adjusting bolt 222, causing it to move axially on the support plate 211, thereby moving the adjusting block 221 and the support wheel 230 together. By adjusting the distance between the two pairs of support wheels 230, the pressure on the fixed rod 100 can be effectively released and dispersed, thereby reducing the risk of breakage of the lower NIP wheel 300.

[0040] When the support wheel 230 is positioned low, the fixing rod 100 located on the support wheel 230 will come into contact with the support plate 211. Therefore, in this embodiment, the support plate 211 has a groove 212 for accommodating the fixing rod 100, and the fixing rod 100 does not contact the groove 212. By providing space for accommodating the fixing rod 100 through the groove 212 on the support plate 211, the fixing rod 100 can remain in a non-contact state with the support plate 211 even when the support wheel 230 is positioned low, thus avoiding friction or collision between the fixing rod 100 and the support plate 211.

[0041] Example 2:

[0042] Based on the same inventive concept as Embodiment 1, refer to Figure 1 and Figure 2 In this embodiment, the NIP wheel retaining device for the washing machine also includes a cleaning assembly 400. The cleaning assembly 400 includes two cleaning plates 410 disposed on the two mutually spaced sidewalls of the two support plates 211. Each cleaning plate 410 has an arc surface coaxial with the fixing rod 100. This allows the cleaning plates 410 to conform to the contour of the lower NIP wheel 300, ensuring stability and accuracy during the cleaning process. A cleaning brush 420 is provided on the arc surface of the cleaning plate 410, used to clean the outer wall of the lower NIP wheel 300. The cleaning brush 420 is made of a soft and wear-resistant material, effectively removing dust and impurities from the outer wall of the lower NIP wheel 300.

[0043] Furthermore, a dust collection trough 430 is detachably connected to the bottom of the cleaning plate 410. This detachable connection allows users to easily install or remove the dust collection trough 430 as needed, facilitating cleaning and maintenance.

[0044] The cleaning plate 410 has a through groove 411 in the middle that communicates with the dust collection trough 430. The dust collection trough 430 is designed to collect dirt and residue removed by the cleaning brush 420, preventing them from scattering around the equipment or re-adhering to the lower NIP wheel 300.

[0045] Furthermore, each cleaning plate 410 is equipped with two cleaning brushes 420, which are located on both sides of the through groove 411. When the NIP wheel 300 rotates, the two cleaning brushes 420 simultaneously scrub the outer wall, ensuring that dirt and residue are thoroughly removed. At the same time, because the cleaning brushes 420 are located on both sides of the through groove 411, they can also effectively guide dirt and debris through the through groove 411 into the dust collection trough 430, avoiding secondary pollution during the cleaning process.
