Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a coating roller adjustment mechanism. Background Technology

[0002] Coating technology is widely used in the surface treatment of various substrates such as paper, film, and textiles, and is a key link in modern industrial production. The core component of coating equipment is the coating roller, which usually consists of two or more rollers working together to achieve precise application and control of the coating on the material surface.

[0003] In coating operations, due to changes in production tasks, long-term wear of rollers, or updates to coating materials, coating rollers need to be disassembled, cleaned, replaced, or maintained periodically. However, existing coating roller mounting structures mostly employ traditional bolt fixing, locating pins, or complex hydraulic / pneumatic locking devices. While these fixing methods provide sufficient stability and pressure, they have significant shortcomings in practical operation: First, the disassembly and installation process consumes a lot of time and often requires the use of special tools or multiple steps, leading to prolonged equipment downtime and severely impacting production efficiency; second, for some precision coating rollers with high concentricity requirements, the cumbersome fastening and positioning steps make it difficult to ensure that high-precision positioning is achieved quickly every time the rollers are installed.

[0004] Therefore, this utility model proposes a coating roller adjustment mechanism to solve the problems of complex disassembly and installation processes and low efficiency of coating rollers in the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a coating roller adjustment mechanism, which aims to improve the problems of complex and time-consuming disassembly and installation processes and low maintenance efficiency of some existing coating roller adjustment mechanisms.

[0006] This utility model provides a coating roller adjustment mechanism, including: a bracket, and a fixed roller disposed at the bottom of the bracket; it also includes an installation mechanism.

[0007] The installation mechanism is located on the side wall of the bracket and is used to lock or release the fixed roller.

[0008] The mounting mechanism includes a fixed block, a pulling assembly, a connecting rod, a locking rod, and a spring. The fixed block is fixedly connected to the outer wall of the bracket by bolts or welding. The pulling assembly is rotatably connected to the fixed block. The pulling assembly includes a handle and two round blocks. The handle is fixedly connected to the two round blocks at its bottom end. The two round blocks have an eccentric structure and rotatably fit against the outer surface of the fixed block. One end of the connecting rod is eccentrically hinged to the pulling assembly, specifically connected to the eccentric position of the round blocks. The other end of the connecting rod passes through the fixed block and the side wall of the bracket and is fixedly connected to the locking rod. The locking rod is slidably disposed inside the bracket, and its end is detachably inserted into the interior of the fixed roller. The spring is sleeved on the outer periphery of the locking rod. The two ends of the spring abut against the limiting boss of the locking rod and the inner wall of the bracket, respectively, to provide the elastic thrust required to lock the fixed roller.

[0009] With this structural combination, the operator can turn the handle to pull back the locking rod by the squeezing action of the eccentric block and overcome the elastic force of the spring, thus achieving quick unlocking and disassembly of the fixed roller.

[0010] Preferably, when the handle is turned to drive the circular block to rotate, the eccentric edge of the circular block can squeeze the fixed block and drive the connecting rod to move away from the fixed roller. The connecting rod simultaneously drives the locking rod to retract, so as to release the lock on the fixed roller.

[0011] Preferably, the coating roller adjustment mechanism further includes a movable roller and an adaptation mechanism. The movable roller is located above the fixed roller, and the two ends of the movable roller are movably connected to the bracket through the adaptation mechanism. The adaptation mechanism is installed on the top of the bracket and is used to provide adaptive height adjustment for the movable roller.

[0012] Preferably, the adaptation mechanism includes a recess, a telescopic rod, a spring, and a sleeve hole formed inside the bracket. The recess supports the end of the moving roller and allows the moving roller to be rotatably positioned within the recess, transmitting the pressure borne by the moving roller downwards.

[0013] Preferably, the telescopic rod is slidably received within the sleeve hole, forming a sliding fit between the telescopic rod and the inner wall of the sleeve hole to provide a guiding function. The recess is fixedly connected to the bottom end of the telescopic rod, and the recess is located outside the sleeve hole or partially received within its open end to support the moving roller.

[0014] Preferably, the second spring is disposed inside the sleeve hole and sleeved onto the outer periphery of the telescopic rod. The bottom end of the second spring abuts against the top of the concave block, and the top end of the second spring abuts against the top wall of the sleeve hole. The second spring is in a pre-compressed state, which can continuously provide downward pressure to the concave block and the moving roller.

[0015] Preferably, there is a gap between the end of the locking rod inserted into the fixed roller and the inner wall of the fixed roller, or a bearing is provided between the two. The bearing, such as a deep groove ball bearing, is located inside the fixed roller and forms a rotational engagement with the end of the locking rod, so as to lock the position of the fixed roller without affecting its normal rotation.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome disassembly and assembly process and low maintenance efficiency of coating rollers in the prior art by setting an installation mechanism on the side wall of the bracket and using the handle to drive the circular block to rotate and generate eccentric displacement, thereby pulling the connecting rod and the locking rod to overcome the spring force and retract. It achieves the technical effect of being able to quickly lock or release the fixed roller and complete the replacement without the need for additional tools, which greatly improves the equipment maintenance efficiency and operation convenience.

[0017] 2. This utility model solves the problem in the prior art that the moving roller cannot automatically adjust its height according to the changes in the thickness of the coating material, resulting in uneven coating pressure or unstable coating quality, by setting an adaptation mechanism at the top of the bracket, using a concave block to support the moving roller, and providing elastic support through the cooperation of a telescopic rod and a spring. It achieves the technical effect that the moving roller can adaptively float with the thickness of the material and maintain a constant flexible pressing force, ensuring the uniformity and integrity of the coating layer and improving product quality.

[0018] 3. This utility model solves the problem of jamming or deflection that may occur in the adjustment process of the adaptation mechanism by sliding cooperation design between the telescopic rod and the inner sleeve hole of the bracket. It achieves the goal of limiting the movement trajectory of the concave block and the moving roller, ensuring smooth and stable lifting adjustment, and further guaranteeing the technical effect of coating operation stability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figure 1 , Figure 2 and Figure 3 The installation mechanism 4 is located on the side wall of the bracket 3. The installation mechanism 4 includes a fixing block 41, a pulling assembly 42, a connecting rod 43, a locking rod 44, and a spring 45. The fixing block 41 is fixedly connected to the outer side wall of the bracket 3. The pulling assembly 42 is rotatably connected to the fixing block 41. Specifically, the pulling assembly 42 includes a handle 421 and two round blocks 422. The bottom end of the handle 421 is fixedly connected to the two round blocks 422 respectively. The two round blocks 422 rotate and fit against the outer surface of the fixing block 41. One end of the connecting rod 43 is eccentrically hinged to the pulling assembly 42. More specifically, the connecting rod 43 is connected to the eccentric position of the round blocks 422. The other end of the connecting rod 43 passes through the fixing block 41 and the side wall of the bracket 3 and is fixedly connected to the locking rod 44. The locking rod 44 is slidably disposed inside the bracket 3. The end of the locking rod 44 is detachably inserted into the interior of the fixed roller 1. The spring 45... A spring 45 is fitted around the outer periphery of the locking rod 44, and the two ends of the spring 45 abut against the limiting boss of the locking rod 44 and the inner wall of the bracket 3, respectively. The spring 45 always provides the locking rod 44 with an elastic thrust toward the fixed roller 1. When the handle 421 is turned to drive the round block 422 to rotate, the eccentric edge of the round block 422 squeezes the fixing block 41 and drives the connecting rod 43 to move away from the fixed roller 1. The connecting rod 43 drives the locking rod 44 to retract against the elastic force of the spring 45, so that the end of the locking rod 44 is disengaged from the inside of the fixed roller 1, releasing the fixed roller 1. When the handle 421 is released, the spring 45 rebounds and pushes the locking rod 44 to re-insert into the fixed roller 1 to achieve locking. To ensure the free rotation of the fixed roller 1, a gap is left between the end of the locking rod 44 inserted into the fixed roller 1 and the inner wall of the fixed roller 1, or a bearing is provided between the two to allow the fixed roller 1 to rotate relative to the locking rod 44.

[0023] Reference Figure 1 , Figure 2 and Figure 3The installation mechanism 4 is located on the side wall of the bracket 3. The installation mechanism 4 includes a fixing block 41, a pulling assembly 42, a connecting rod 43, a locking rod 44, and a spring 45. The fixing block 41 is fixedly connected to the outer side wall of the bracket 3. The pulling assembly 42 is rotatably connected to the fixing block 41. Specifically, the pulling assembly 42 includes a handle 421 and two round blocks 422. The bottom end of the handle 421 is fixedly connected to the two round blocks 422 respectively. The two round blocks 422 rotate and fit against the outer surface of the fixing block 41. One end of the connecting rod 43 is eccentrically hinged to the pulling assembly 42. More specifically, the connecting rod 43 is connected to the eccentric position of the round blocks 422. The other end of the connecting rod 43 passes through the fixing block 41 and the side wall of the bracket 3 and is fixedly connected to the locking rod 44. The locking rod 44 is slidably disposed inside the bracket 3. The end of the locking rod 44 is detachably inserted into the interior of the fixed roller 1. The spring 45... A spring 45 is fitted around the outer periphery of the locking rod 44, and the two ends of the spring 45 abut against the limiting boss of the locking rod 44 and the inner wall of the bracket 3, respectively. The spring 45 always provides the locking rod 44 with an elastic thrust toward the fixed roller 1. When the handle 421 is turned to drive the round block 422 to rotate, the eccentric edge of the round block 422 squeezes the fixing block 41 and drives the connecting rod 43 to move away from the fixed roller 1. The connecting rod 43 drives the locking rod 44 to retract against the elastic force of the spring 45, so that the end of the locking rod 44 is disengaged from the inside of the fixed roller 1, releasing the fixed roller 1. When the handle 421 is released, the spring 45 rebounds and pushes the locking rod 44 to re-insert into the fixed roller 1 to achieve locking. To ensure the free rotation of the fixed roller 1, a gap is left between the end of the locking rod 44 inserted into the fixed roller 1 and the inner wall of the fixed roller 1, or a bearing is provided between the two to allow the fixed roller 1 to rotate relative to the locking rod 44.

[0024] It also includes a movable roller 2 and an adaptation mechanism 5. The movable roller 2 is located above the fixed roller 1. The two ends of the movable roller 2 are movably connected to the support 3 through the adaptation mechanism 5. The adaptation mechanism 5 is set on the top of the support 3 to enable the movable roller 2 to adaptively adjust its height.

[0025] Reference Figure 4The adapting mechanism 5 includes a recess 51, a telescopic rod 52, a second spring 53, and a sleeve hole 54 opened inside the bracket 3. The shape of the recess 51 is adapted to the end shape of the moving roller 2. The end of the moving roller 2 is rotatably supported in the recess 51. The recess 51 is used to transmit the pressure borne by the moving roller 2 downward to the telescopic rod 52. The telescopic rod 52 is slidably received in the sleeve hole 54. The cooperation between the telescopic rod 52 and the sleeve hole 54 forms a sliding guide structure to ensure that the recess 51 can rise and fall smoothly and vertically without deflection. The recess 51 is fixedly connected to the bottom end of the telescopic rod 52. The recess 51 is located outside the sleeve hole 54 or partially received in its open end. The second spring 53 is set in the sleeve hole 54. The inner part of the spring 53 is sleeved on the outer periphery of the telescopic rod 52. The bottom end of the spring 53 abuts against the top of the concave block 51, and the top end of the spring 53 abuts against the top wall of the sleeve hole 54. The spring 53 is in a compressed state, providing a continuous downward pushing force to the concave block 51, thereby ensuring the pressing effect of the moving roller 2 on the coating material. The end of the locking rod 44 inserted into the fixed roller 1 leaves a gap between it and the inner wall of the fixed roller 1, or a bearing is provided between the two. The bearing, such as a deep groove ball bearing, is provided inside the fixed roller 1 and forms a rotational engagement with the end of the locking rod 44, so as to allow the fixed roller 1 to rotate relative to the locking rod 44 during the coating process. At the same time, the locking rod 44 can reliably lock the fixed roller 1 on the bracket 3.

[0026] The implementation principle of this application embodiment is as follows: When it is necessary to disassemble the fixed roller 1, the operator pulls the handle 421, which drives the two round blocks 422 to rotate. During the rotation, the eccentric edge of the round block 422 presses the outer surface of the fixed block 41. Using the eccentric principle, the connecting rod 43 is forced to move away from the fixed roller 1. The connecting rod 43 drives the locking rod 44 to retract synchronously through the fixed connection. During the retraction process, the locking rod 44 compresses the spring 45 until the end of the locking rod 44 is completely disengaged from the interior of the fixed roller 1. At this time, the fixed roller 1 is in the unlocked state and can be easily removed for maintenance or replacement. When installing the fixed roller 1, it is pushed into the installation position of the bracket 3, and then the handle 421 is released. Under the action of the spring 45, the locking rod 44 is automatically pushed out and re-inserted into the interior of the fixed roller 1, thereby realizing the quick locking of the fixed roller 1.

[0027] During the coating process, the end of the moving roller 2 rotates and is supported in the recess 51 of the adapting mechanism 5. When the thickness of the coating material changes, for example, when the thickness increases, the coating material will push the moving roller 2 to float upward. The moving roller 2 drives the recess 51 to move upward synchronously. The recess 51 pushes the telescopic rod 52 to move upward. The telescopic rod 52 slides inside the sleeve hole 54 and further compresses the second spring 53. The compressed second spring 53 generates an increased downward reaction force, which is continuously applied to the moving roller 2 through the recess 51, ensuring that the moving roller 2 always maintains a constant coating pressure on the coating material. When the thickness of the coating material decreases, the elastic force of the second spring 53 pushes the recess 51 and the moving roller 2 downward, always maintaining a pressed state. The sliding cooperation of the telescopic rod 52 in the sleeve hole 54 ensures the smoothness of the moving roller 2's lifting and lowering movement.
