Description

Technical Field

[0001] This utility model relates to the technical field of multilayer board cleaning devices, specifically a cleaning device for multilayer board processing. Background Technology

[0002] In the engineered wood products and furniture manufacturing industry, multi-layer solid wood board (also known as plywood) is a common substrate made by hot-pressing an odd number of layers of wood veneer with adhesives. It is widely used in furniture, flooring, and decorative panels. During the sawing, sanding, and drilling processes of multi-layer solid wood board, its surface and sides are prone to generating contaminants such as sawdust, powder, resin residue, and small amounts of oil stains. These impurities not only affect the adhesion of subsequent coatings, veneers, or paints, but may also lead to defects in the appearance of the finished product or accelerate mold and decay, seriously affecting product quality and service life. Therefore, effective cleaning of multi-layer solid wood board between key processes or before leaving the factory is crucial. Currently, traditional equipment mostly relies on water rinsing or static brush friction, which is insufficient for removing highly adhesive contaminants and has poor cleaning effect. Utility Model Content

To solve the above problems, the cleaning components are designed so that a servo motor drives a cam to strike a brush, causing it to vibrate back and forth under the action of a spring. Combined with water spraying, this achieves efficient water brush cleaning of the upper and lower surfaces of the multilayer board. At the same time, adjustable limiting plates and their soft bristles on both sides of the conveyor table limit the multilayer board and clean its sides, thus improving the cleaning effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for multi-layer board processing, comprising: a cleaning tank, a water storage tank installed on the top of the cleaning tank, a conveyor platform fixedly connected to one side of the cleaning tank, and a cleaning assembly disposed between the cleaning tank and the conveyor platform.

One end of both the guide pipe a and the guide pipe b is fixedly connected to a water spray box, and both ends of the water spray box are fixedly connected to the two sides of the inner wall of the cleaning chamber. Multiple water spray holes are opened on one side of the water spray box.

[0021] This application provides a cleaning device for multilayer board processing. This device, through the arrangement of its cleaning components, utilizes a servo motor to drive a cam to impact a brush, causing it to reciprocate under spring pressure. Combined with water spraying, this achieves efficient water-brush cleaning of the upper and lower surfaces of the multilayer board. Simultaneously, adjustable limiting plates and their soft bristles on both sides of the conveyor table limit the movement of the multilayer board and clean its sides, improving the cleaning effect. The following provides a detailed description of this multilayer board cleaning device. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figure 1-6 In this embodiment, a cleaning device for multilayer board processing is provided, comprising: A cleaning tank 1 is provided, with a water storage tank 3 installed on its top and a conveyor table 2 fixedly connected to one side of the cleaning tank 1. A cleaning assembly is provided between the cleaning tank 1 and the conveyor table 2. The cleaning assembly includes: a water pump 4 fixedly installed on the top of the cleaning tank 1; a servo motor 6 installed on one side of the cleaning tank 1; a cam 602 driven by a rotating shaft on one side of the servo motor 6; a cleaning chamber 104 opened on one side of the cleaning tank 1; two brushes 603 inside the cleaning chamber 104; two spring cavities 605 opened on one side of the inner wall of the cleaning chamber 104; springs 604 inside each of the two spring cavities 605; and two limiting plates 7 inside the conveyor table 2, with multiple soft bristles 701 on one side of each of the two limiting plates 7.

[0024] The cleaning components are designed so that the servo motor 6 drives the cam 602 to intermittently strike the impact block 601, causing the brush 603 to vibrate back and forth under the elastic action of the spring 604. At the same time, the water pump 4 sprays water from the water storage tank 3 evenly through the spray box 5 to perform water rinsing and brushing on the surface of the multilayer board, achieving efficient cleaning of the upper and lower surfaces. Secondly, the adjustable limit plates 7 on both sides of the conveyor table 2 and the soft bristles 701 on them limit the multilayer board and clean the sides of the multilayer board, avoiding uneven cleaning or equipment jamming due to board displacement, thus improving the stability of the multilayer board movement and the cleaning effect.

[0025] Two brushes 603 are fixedly connected at one end to two springs 604. Two perforations 106 are opened on one side of the inner wall of the cleaning chamber 104. One end of each brush 603 passes through the two perforations 106 and is fixedly connected to an impact block 601. A sewage chamber 101 is opened inside the cleaning tank 1. Two mounting cavities 102 are opened on the top of the inner wall of the sewage chamber 101. A grid plate 103 is fixedly installed inside each of the two mounting cavities 102. A slot 105 is opened between the sewage chamber 101 and the cleaning chamber 104. One side of the water pump 4 is connected to A water pump 4 is connected to a water outlet pipe 402 on one side. One end of the water pump 401 is connected to the water storage tank 3, and the other end of the water pump 4 is connected to the water outlet pipe 402. One end of the water outlet pipe 402 is connected to a guide pipe a403 via a T-connector, and the other end of the water outlet pipe 402 is connected to a guide pipe b404 via a T-connector. One end of both the guide pipe a403 and the guide pipe b404 is fixedly connected to a spray box 5, and both ends of the spray box 5 are fixedly connected to the two sides of the inner wall of the cleaning chamber 104. Multiple spray holes 501 are opened on one side of the spray box 5.

[0026] In use, the water pump 4 is activated via the controller on one side of the conveyor platform 2 to draw water from the water storage tank 3. The water is then diverted through the pump pipe 401 and the outlet pipe 402 to the guide pipes a403 and b404, respectively, and enters the spray box 5 connected to the guide pipes a403 and b404. The water is then sprayed out through the spray holes 501 on one side of the spray box 5. Since the spray holes 501 on both spray boxes 5 are oriented towards the cleaning chamber 104, the water will spray onto the cleaning chamber 104 when it is sprayed out. On the brush 603, the servo motor 6 is then turned on by the controller on one side of the conveyor table 2. The servo motor 6 rotates the cam 602 to intermittently strike the impact block 601. When the cam 602 strikes the impact block 601, the impact block 601 pushes the two brushes 603 to squeeze the two springs 604. When the cam 602 moves away from the impact block 601, the spring 604 is released, pushing the two brushes 603 to reset. This process is repeated, which can make the two brushes 603 vibrate left and right.

[0027] When the multilayer board to be cleaned is pushed into the cleaning chamber 104 by the push plate 205, the two sides of the multilayer board will rub against the soft bristles 701. At this time, the soft bristles 701 can clean the two sides of the multilayer board. When the multilayer board is moved between the two brushes 603, the left and right vibration of the brushes 603 will cause the soft bristles 701 on the brushes 603 to rub against the upper and lower surfaces of the multilayer board. Together with the water sprayed from the water spray hole 501, the multilayer board is cleaned. The cleaned water will flow into the sewage chamber 101 through the grid plate 103 and the slot 105 for collection.

[0028] When the servo motor 202 drives the slider 204 to the end of the lead screw 203, the push plate 205 is reset by reversing the lead screw 203. Then, a new plate is placed in and pushed into the cleaning chamber 104. The previous plate is moved out of the cleaning chamber 104 by the plate-to-plate method.

[0029] The conveyor platform 2 has a limit groove 201 on its top and a servo motor 202 installed at its bottom. A lead screw 203 is driven to one side of the servo motor 202 via a rotating shaft. One end of the lead screw 203 is connected to the cleaning tank 1 via a bearing. A slider 204 is provided on the outside of the lead screw 203. Two threaded rods 702 are fixedly connected to one side of the two limit plates 7. A threaded hole that mates with the lead screw 203 is provided on one side of the slider 204. Two nuts are threadedly connected to the outside of the threaded rod 702. One end of the slider 204 passes through the limit groove 201 and is fixedly connected to a push plate 205. Two through holes that mate with the threaded rods 702 are provided on both sides of the conveyor platform 2.

[0030] In use, tighten the nut on the outside of the threaded rod 702, then release the nut from limiting the threaded rod 702 and the limiting plate 7. Move the limiting plate 7 according to the width of the multilayer board to be cleaned, so that the distance between the two limiting plates 7 is slightly greater than the width of the multilayer board. Then tighten the two nuts on the threaded rod 702 to bring the two limiting plates 7 closer to each other and into contact with the conveyor table 2, thereby fixing the threaded rod 702 and the limiting plate 7.

[0031] The working principle is as follows: In use, tighten the nut on the outside of the threaded rod 702, then release the nut from limiting the threaded rod 702 and the limiting plate 7. Move the limiting plate 7 according to the width of the multilayer board to be cleaned, so that the distance between the two limiting plates 7 is slightly greater than the width of the multilayer board. Then tighten the two nuts on the threaded rod 702 to bring the two limiting plates 7 closer to each other and into contact with the conveyor table 2, thereby fixing the threaded rod 702 and the limiting plate 7.

[0032] Furthermore, the plate is placed on top of the conveyor table 2 and positioned on one side of the push plate 205. Then, the servo motor 202 is started by the controller on one side of the conveyor table 2 to drive the lead screw 203 to rotate, thereby driving the slider 204 along one end of the lead screw 203 and driving the push plate 205 to push the plate towards the cleaning chamber 104.

[0033] At the same time, the water pump 4 is activated by the controller on one side of the conveyor platform 2 to draw water from the water storage tank 3. The water is then diverted through the water pumping pipe 401 and the water outlet pipe 402 to the guide pipes a403 and b404, and enters the spray box 5 connected to the guide pipes a403 and b404 respectively. The water is then sprayed out through the spray hole 501 on one side of the spray box 5. Since the spray holes 501 on the two spray boxes 5 are oriented towards the cleaning chamber 104, the water will spray onto the cleaning chamber 104 when it is sprayed out. On the brush 603, the servo motor 6 is then turned on by the controller on one side of the conveyor table 2. The servo motor 6 rotates the cam 602 to intermittently strike the impact block 601. When the cam 602 strikes the impact block 601, the impact block 601 pushes the two brushes 603 to squeeze the two springs 604. When the cam 602 moves away from the impact block 601, the spring 604 is released, pushing the two brushes 603 to reset. This process is repeated, which can make the two brushes 603 vibrate left and right.

[0034] When the multilayer board to be cleaned is pushed into the cleaning chamber 104 by the push plate 205, the two sides of the multilayer board will rub against the soft bristles 701. At this time, the soft bristles 701 can clean the two sides of the multilayer board. When the multilayer board is moved between the two brushes 603, the left and right vibration of the brushes 603 will cause the soft bristles 701 on the brushes 603 to rub against the upper and lower surfaces of the multilayer board. Together with the water sprayed from the water spray hole 501, the multilayer board is cleaned. The cleaned water will flow into the sewage chamber 101 through the grid plate 103 and the slot 105 for collection.

[0035] When the servo motor 202 drives the slider 204 to the end of the lead screw 203, the push plate 205 is reset by reversing the lead screw 203. Then, a new plate is placed in and pushed into the cleaning chamber 104. The previous plate is moved out of the cleaning chamber 104 by the plate-to-plate method.

[0036] Furthermore, the servo motor 202 uses a built-in encoder to detect the position and speed of the shaft in real time, transmitting the feedback signal to the driver. The driver compares the actual values ​​with the control commands and uses a closed-loop control algorithm to dynamically adjust the motor's current and torque, thereby precisely controlling the rotation angle, direction, and speed. The rotation direction is determined by a direction command signal sent from the host controller to the driver. The driver interprets the target motion direction based on this command and, combined with the rotor position information fed back by the encoder, adjusts the output timing and current phase of the three-phase inverter circuit using a vector control algorithm. This changes the direction of the rotating magnetic field generated in the stator windings, driving the permanent magnet rotor to rotate in the specified direction. The encoder continuously provides feedback on the actual motion direction, and the driver verifies and corrects deviations in real time under closed-loop control, ensuring that the motor's running direction matches the command. Moreover, after reaching the target position, the system continues to monitor the position deviation. If an external force causes a shift, the driver immediately outputs a reverse torque to pull the rotating shaft back to its original position, achieving electronic locking of the rotating shaft. This feedback-based closed-loop control mechanism enables the servo motor 202 to move precisely and maintain a stable position at the specified location. Since the rotation angle, rotation direction, and speed control of the servo motor 202, as well as the electronic locking of rotation, are mature and conventional technologies, they will not be described in detail further.
