During the production process, its surface often has problems such as burrs and unevenness, which often require the use of sanding equipment to sand in order to improve the surface quality.

[0003] However, most existing grinding equipment uses a combination of manual feeding and mechanical grinding, which is not only labor-intensive but also inefficient. Utility Model Content

[0004] This utility model aims to address the shortcomings of the prior art by providing a wood-plastic composite board sanding device. To solve the above problems, a hydraulic cylinder drives a pull rod and a support plate to lift and lower in tandem, thereby achieving the step-by-step lifting of stacked wood-plastic composite boards and ensuring that each board enters the pushing zone sequentially. At the same time, a servo motor drives a lead screw to move the push plate horizontally along the limiting groove, stably pushing the board through the discharge port to the rotating roller, completing continuous automatic feeding, reducing manual intervention, and improving sanding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wood-plastic composite board sanding device, comprising: a sanding box, two fixed plates fixedly installed on one side of the sanding box, a feeding box fixedly connected to one side of the two fixed plates, and a feeding assembly disposed on one side of the sanding box. The feeding assembly includes: a servo motor fixedly installed on one side of the feeding box, a lead screw driven by a rotating shaft on one side of the servo motor, a push plate provided on the outer side of the lead screw, a mounting plate fixedly connected to one side of the push plate, a position sensor installed at the bottom of the mounting plate, a microcontroller installed inside the mounting plate, hydraulic cylinders installed on both sides of the feeding box, connecting plates fixedly connected to the top of the two hydraulic cylinders, pull rods fixedly connected to the four corners of the bottom of the connecting plate, and support plates fixedly connected to the bottom ends of the four pull rods.

[0007] Preferably, the inner wall of the grinding chamber is provided with grooves on both sides, and the top and bottom of the inner wall of the two grooves are provided with multiple soft bristles.

[0008] Preferably, two rotating rollers are connected between the two fixed plates via bearings. One end of each of the two rotating rollers is driven by a servo motor via a rotating shaft. Two limiting plates are provided between the two fixed plates. A through hole is opened on one side of each of the two fixed plates. Two screws are fixedly connected to one side of each of the two limiting plates. Both screws pass through the through hole on the fixed plate. Two nuts are threaded onto each of the two screws.

[0009] Preferably, the top of the feeding box is provided with a feeding groove, one side of the push plate is provided with a threaded hole that cooperates with the lead screw, and one end of the lead screw passes through the threaded hole on the push plate and is connected to one side of the inner wall of the feeding groove through a bearing.

This ensures that only the top layer of boards enters the pushing operation area each time. At the same time, through the coordinated operation of the position sensor and the microcontroller, the vertical position of the top layer of wood-plastic composite board on the support plate can be monitored in real time.

[0025] This application provides a wood-plastic composite board (WPC) sanding device. This device uses a hydraulic cylinder to drive a pull rod and a support plate to lift and lower the stacked WPC boards sequentially, ensuring each board enters the pushing zone in turn. Simultaneously, a servo motor drives a lead screw to move a push plate horizontally along a limiting groove, stably pushing the board through the discharge port to the rotating roller, completing continuous automatic feeding, reducing manual intervention, and improving sanding efficiency. The following provides a detailed description of this WPC sanding 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.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1-8 In this embodiment, a wood-plastic composite board sanding device is provided, including: a sanding box 1, two fixing plates 2 are fixedly installed on one side of the sanding box 1, and a feeding box 3 is fixedly connected to one side of the two fixing plates 2; a feeding assembly is provided on one side of the sanding box 1, the feeding assembly includes: a servo motor 4 is fixedly installed on one side of the feeding box 3, a lead screw 401 is driven and connected to one side of the servo motor 4 via a rotating shaft, a push plate 402 is provided on the outside of the lead screw 401, a mounting plate 403 is fixedly connected to one side of the push plate 402, a position sensor 406 is installed at the bottom of the mounting plate 403, a microcontroller 405 is installed inside the mounting plate 403, hydraulic cylinders 602 are installed on both sides of the feeding box 3, a connecting plate 6 is fixedly connected to the top of each of the two hydraulic cylinders 602, a pull rod 601 is fixedly connected to the four corners of the bottom of the connecting plate 6, and a support plate 605 is fixedly connected to the bottom of the four pull rods 601.

[0028] The hydraulic cylinder 602 and the support plate 605 in the feeding assembly work together to drive the pull rod 601 to smoothly raise and lower the support plate 605 in the vertical direction, thereby lifting the stacked wood-plastic composite boards step by step. This ensures that only the top layer of boards enters the pushing operation area each time. At the same time, through the coordinated operation of the position sensor 406 and the microcontroller 405, the vertical position of the top layer of wood-plastic composite board on the support plate 605 can be monitored in real time. When the board rises to the preset height, the position sensor 406 sends an electrical signal to the microcontroller 405, which automatically stops the hydraulic cylinder 602, achieving precise positioning and avoiding material jamming caused by multiple boards being stacked during feeding.

[0029] Secondly, the servo motor 4 drives the lead screw 401 to rotate, which in turn drives the push plate 402 to move horizontally along the axis of the lead screw 401. With the help of the sliding connection structure between the push plate 402 and the limiting groove 501, the single wood-plastic board is stably pushed, ensuring that the board accurately passes through the discharge port 302 and is transported to the rotating roller 201, so as to realize the continuous feeding of wood-plastic board, reduce manual intervention, and improve sanding efficiency.

[0030] The grinding box 1 has a grinding cavity 101 inside. A door panel 102 is installed on one side of the grinding box 1 via a hinge. A lower grinding roller 8 is installed inside the grinding cavity 101. A motor b801 is installed on one side of the grinding box 1. One side of the motor b801 is connected to the lower grinding roller 8 via a rotating shaft. One end of the lower grinding roller 8 is connected to one side of the inner wall of the grinding cavity 101 via a bearing. An installation box 7 is provided inside the grinding cavity 101. An upper grinding roller 701 is provided inside the installation box 7. One end of the upper grinding roller 701 is connected to the installation box 7 via a bearing. A motor a702 is installed on one side of the installation box 7. One side of the motor a702 is connected to the upper grinding roller 701 via a rotating shaft. An electric telescopic rod 106 is installed on the top of the grinding box 1. The bottom end of the electric telescopic rod 106 is fixedly connected to the installation box 7. Grooves 103 are opened on both sides of the inner wall of the grinding cavity 101. Multiple soft bristles are provided on the top and bottom of the inner wall of the two grooves 103.

[0031] Two rotating rollers 201 are connected between the two fixed plates 2 via bearings. One end of each rotating roller 201 is connected to a servo motor 205 via a rotating shaft. Two limiting plates 204 are provided between the two fixed plates 2. Each of the two fixed plates 2 has a through hole on one side. Each of the two limiting plates 204 has two screws 202 fixedly connected to one side. Both screws 202 pass through the through holes on the fixed plates 2. Each screw 202 is threaded with two nuts 203.

[0032] In use, the servo motor 205 rotates the rotating roller 201 to drive the wood-plastic board through the slot 103 and move it between the upper sanding roller 701 and the lower sanding roller 8. At this time, the motors a702 and b801 are turned on to drive the upper sanding roller 701 and the lower sanding roller 8 to rotate, so that the upper and lower surfaces of the wood-plastic board can be sanded.

[0033] The feed box 3 has a feed trough 301 on its top, a threaded hole for cooperating with a lead screw 401 on one side of a push plate 402, and one end of the lead screw 401 passes through the threaded hole on the push plate 402 and is connected to one side of the inner wall of the feed trough 301 through a bearing. A battery 404 is installed inside the mounting plate 403. A crossbeam 5 is fixedly connected inside the feed trough 301. A limit groove 501 is opened at the bottom of the crossbeam 5. The limit groove 501 is slidably connected to the push plate 402. A discharge port 302 is opened on one side of the feed box 3. A number of limit screw holes 604 are opened on the top of the support plate 605. A number of limit rods 603 are provided on the top of the support plate 605. The bottom of the multiple limit rods 603 is provided with external threads, and the limit screw holes 604 are threaded to the bottom of the limit rods 603.

[0034] In use, according to the width of the wood-plastic composite board, the two rows of limiting rods 603 are screwed into the corresponding limiting screw holes 604, so that the distance between the two rows of limiting rods 603 is close to the width of the wood-plastic composite board. Then, multiple wood-plastic composite boards are neatly stacked on top of the support plate 605. The hydraulic cylinder 602 is extended by the controller located on one side of the grinding box 1, which drives the connecting plate 6, multiple tie rods 601 and the support plate 605 to move upward. At this time, the position sensor 406 is energized, and the position sensor 406 detects the wood-plastic composite boards stacked on the top of the support plate 605. When the topmost wood-plastic composite board reaches a preset threshold, the position sensor 406 generates an electrical signal, closing the two hydraulic cylinders 602. At this time, one side of the topmost wood-plastic composite board is located on the side of the discharge port 302. Simultaneously, the servo motor 4 is started, driving the lead screw 401 to rotate, thereby causing the lead screw 401 to rotate in the threaded hole on one side of the push plate 402, which in turn causes the push plate 402 to move along the lead screw 401, and drives the topmost wood-plastic composite board to move closer to the discharge port 302, until the wood-plastic composite board passes through the discharge port 302 and moves onto the rotating roller 201.

[0035] Furthermore, the position sensor 406 is a laser displacement sensor, model JGWY3. In use, the position sensor 406 measures the target object and outputs an electrical signal based on the measurement result. These raw electrical signals are input into the microcontroller, which processes the signals and compares the processed signals with a preset threshold or target value. This solution does not improve the circuit or program of the position sensor 406, so the circuit and signal connection relationship of the position sensor 406 will not be described in detail.

[0036] The working principle is as follows: In use, based on the width of the wood-plastic composite board, the two rows of limiting rods 603 are screwed into the corresponding limiting screw holes 604, so that the distance between the two rows of limiting rods 603 is close to the width of the wood-plastic composite board. Then, multiple wood-plastic composite boards are neatly stacked on top of the support plate 605. The hydraulic cylinder 602 is extended by the controller located on one side of the grinding box 1, which drives the connecting plate 6, multiple tie rods 601, and the support plate 605 to move upward. At this time, the position sensor 406 is energized. The position sensor 406 detects the topmost wood-plastic composite board stacked on the support plate 605. When the position sensor 406 detects that the topmost wood-plastic composite board has reached a preset threshold, the position sensor 406 generates an electrical signal and transmits it to the microcontroller 405. The microcontroller 405 then closes the two hydraulic cylinders 602. At this time, the topmost wood-plastic composite board is positioned to one side. At the discharge port 302 side, the servo motor 4 is started simultaneously, driving the lead screw 401 to rotate, so that the lead screw 401 rotates in the threaded hole on the side of the push plate 402, thereby causing the push plate 402 to move along the lead screw 401, and driving the topmost wood-plastic board to move closer to the discharge port 302, until the wood-plastic board passes through the discharge port 302 and moves onto the rotating roller 201. At this time, the two limiting plates 204 can limit the two sides of the wood-plastic board to prevent the wood-plastic board from deviating during the conveying process. The servo motor 205 rotates the rotating roller 201 to drive the wood-plastic board through the slot 103 and move it between the upper grinding roller 701 and the lower grinding roller 8. At this time, the motors a702 and b801 are turned on to drive the upper grinding roller 701 and the lower grinding roller 8 to rotate, so that the upper and lower surfaces of the wood-plastic board can be ground.

[0037] After the first wood-plastic composite board is completely removed from the discharge port 302, the hydraulic cylinder 602 continues to extend, causing the wood-plastic composite board stacked on the support plate 605 to continue to move upward, so that the second wood-plastic composite board moves to the bottom of the position sensor 406. The position sensor 406 generates an electrical signal again, which is transmitted to the position sensor 406 and the hydraulic cylinder 602 is closed. Then, the servo motor 4 is started to drive the push plate 402 to push the second wood-plastic composite board out of the discharge port 302 and bring it into the grinding chamber 101 for grinding. When the second board is removed from the feed trough 301, it abuts against the end of the first board, which can prevent the first board from moving backward during grinding.

[0038] In addition, servo motor 4 and servo motor 205 can detect the position and speed of the shaft in real time through the built-in encoder, and transmit the feedback signal to the driver. The driver compares the actual value with the control command and uses a closed-loop control algorithm to dynamically adjust the current and torque of the motor, thereby accurately controlling the rotation angle and speed.
