Description

Technical Field

[0001] This utility model relates to the field of processing technology of Pinus sylvestris bed boards, specifically a device for cleaning burrs on the edges of Pinus sylvestris bed boards. Background Technology

[0002] Scots pine has advantages such as toughness, beautiful grain, and strong corrosion resistance, and its cost is relatively low, making it a commonly used wood for making bed boards.

[0003] For example, a PVC decorative panel deburring device with authorization announcement number "CN221967613U" uses an electric telescopic rod at the upper end of an iron base frame to drive the panel in the middle of the clamping frame to move telescopically, effectively feeding the panel automatically to the middle of the deburring assembly, facilitating back-and-forth friction treatment of the panel's sides. However, the deburring assembly of this device consists of a clamping plate, a connecting plate, and a frosted stone plate. The frosted stone plate is located on the inner side wall of the clamping plate and the connecting plate. Only the front and back sides of the panel being clamped can contact the frosted stone plate for friction deburring. It cannot complete the deburring of all four sides of the panel at once. The panel needs to be removed, the distance between the two deburring assemblies adjusted, and the panel rotated and then put back in. This process of removing and putting in adds to the operation steps, and after each adjustment of the two deburring assemblies, they need to be aligned and fixed, making the operation cumbersome and reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that only the front and back sides of the board being clamped can contact the frosted stone board and perform friction deburring operation, making it impossible to complete the deburring work on all four sides of the board at once. Therefore, a pine bed board edge burr cleaning device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A device for cleaning burrs on the edge of a pine bed board is designed, comprising a box and a second rectangular frame. The second rectangular frame is fixedly connected to both sides of the inner wall of the box. The box has a pine bed board grinding structure inside. A second conveyor belt is installed inside the second rectangular frame. A second sanding belt is fixedly connected to the outer wall of the second conveyor belt. A pine bed board moving structure is provided on the upper side of the inner wall of the box.

[0006] Preferably, the pine bed board grinding structure includes a first servo motor, the outer wall of the first servo motor is fixedly connected to the housing, the output shaft of the first servo motor is fixedly connected to a round rod, both ends of the round rod are rotatably connected to the housing through bearings, both sides of the outer wall of the round rod are fixedly connected to threaded rods, the threaded rods are threadedly connected to threaded blocks, the lower end of the threaded blocks is fixedly connected to a square block, the inner wall of the square block is slidably connected to a sliding rod, and both ends of the sliding rod are fixedly connected to the housing.

[0007] Preferably, the threaded block is fixedly connected to the first rectangular frame via a protrusion machined at its upper end. A first conveyor belt is installed inside the first rectangular frame, and a first sanding belt is fixedly connected to the outer wall of the first conveyor belt.

[0008] Preferably, a second servo motor is fixedly connected to the upper end of the first rectangular frame, and the output shaft of the second servo motor is connected to the power roller of the first conveyor belt.

[0009] Preferably, the movable structure of the pine bed board includes a vertical block, the upper end of which is fixedly connected to the box body, the inner wall of which is rotatably connected to a cylinder via a bearing, and a circular roller is fixedly connected to the outer wall of the cylinder, with a rubber sleeve installed on the outer wall of the circular roller.

[0010] Preferably, a third servo motor is fixedly connected to the upper end of the second rectangular frame, and the output shaft of the third servo motor is connected to the power roller of the second conveyor belt.

[0011] The present invention provides a device for cleaning burrs on the edges of a Pinus sylvestris bed board. The advantages are as follows: Through the cooperation of the Pinus sylvestris bed board grinding structure and the Pinus sylvestris bed board moving structure, the output shaft of the first servo motor rotates, driving a round rod to rotate. The rotation of the round rod drives two threaded rods to rotate, with the threads of the two threaded rods in opposite directions. The rotation of the threaded rods drives the threaded blocks to move, which in turn causes two square blocks to slide outwards simultaneously on a sliding rod. The movement of the threaded blocks causes two first rectangular frames to move outwards simultaneously until the two threaded blocks reach their outermost ends. At this point, the first servo motor is turned off. The Pinus sylvestris bed board is then placed on the round roller, with the rightmost end of the bed board placed on the rightmost round roller. The outer wall of the round roller is fitted with a rubber sleeve. The rubber is soft and elastic, preventing the round roller from scratching or abrading the Pinus sylvestris bed board when it comes into contact with the roller. This device completes the deburring of all four sides of the Pinus sylvestris bed board in one operation, eliminating the need to clean two sides of the bed board before removing and fixing it, thus improving work efficiency.

[0014] The present invention will be further described below with reference to the accompanying drawings: See attached document Figures 1-6 In this embodiment, a pine bed board edge burr cleaning device includes a box 1 and a second rectangular frame 8. The second rectangular frame 8 is fixedly connected to both sides of the inner wall of the box 1. The box 1 is provided with a pine bed board grinding structure 2. The second rectangular frame 8 is installed inside the second conveyor belt 10. The second conveyor belt 10 is composed of two toothed pulleys and a toothed belt. The outer wall of the second conveyor belt 10 is fixedly connected to a second sanding belt 11. The upper side of the inner wall of the housing 1 is provided with a pine bed board moving structure 3. The threaded block 204 is fixedly connected to the first rectangular frame 4 through the upper protrusion. The first rectangular frame 4 is equipped with a first conveyor belt 5, which consists of two toothed pulleys and a toothed belt. The outer wall of the first conveyor belt 5 is fixedly connected with a first sanding belt 6. The upper end of the first rectangular frame 4 is fixedly connected with a second servo motor 7. The second servo motor 7 is electrically connected to the battery through wires. A switch is opened on the battery, and the switch is connected to an external remote control device. The output shaft of the second servo motor 7 is connected to the power roller of the first conveyor belt 5. The output shaft of the second servo motor 7 is connected to the active toothed pulley of the first conveyor belt 5. The rotation of the active gear drives the rotation of another toothed pulley through the toothed belt. The upper end of the second rectangular frame 8 is fixedly connected to the third servo motor 9. The output shaft of the third servo motor 9 is connected to the power roller of the second conveyor belt 10. The output shaft of the third servo motor 9 is connected to the active toothed pulley of the second conveyor belt 10. The rotation of the active gear drives the rotation of another toothed pulley through the toothed belt.

[0015] See attached document Figure 1 and Figure 4The pine bed board grinding structure 2 includes a first servo motor 201. The outer wall of the first servo motor 201 is fixedly connected to the housing 1. The output shaft of the first servo motor 201 is fixedly connected to a round rod 202. Both ends of the round rod 202 are rotatably connected to the housing 1 through bearings. The round rod 202 rotates inside the housing 1 through the bearings. Both sides of the outer wall of the round rod 202 are fixedly connected to threaded rods 203. The threaded rods 203 are threadedly connected to threaded blocks 204. The lower end of the threaded blocks 204 is fixedly connected to a square block 205. The inner wall of the square block 205 is slidably connected to a sliding rod 206. The square block 205 slides on the sliding rod 206. Both ends of the sliding rod 206 are fixedly connected to the housing 1. The sliding rod 206 limits the threaded blocks 203 to prevent the threaded blocks 204 from rotating with the rotation of the threaded rod 203.

[0016] See attached document Figures 1-5 The movable structure 3 of the pine bed board includes a vertical block 301. The upper end of the vertical block 301 is fixedly connected to the housing 1. The inner wall of the vertical block 301 is rotatably connected to the cylinder 302 through a bearing. The cylinder 302 rotates inside the vertical block 301 through the bearing. A roller 303 is fixedly connected to the outer wall of the cylinder 302. When the pine bed board is pushed, the roller 303 will roll along with the movement of the pine bed board. This rolling motion helps to reduce resistance and reduce the force required to push. A rubber sleeve 304 is installed on the outer wall of the roller 303. The rubber is soft and elastic. When the pine bed board comes into contact with the roller 303, it can prevent the roller 303 from scratching or wearing the pine bed board.

[0017] Working principle: When using the pine bed board edge burr removal device: Preparation phase: When the external power supply of the first servo motor 201 is connected and the first servo motor 201 is started, the output shaft of the first servo motor 201 rotates, driving the round rod 202 to rotate (e.g. Figure 4 The rotation of the round rod 202 drives the two threaded rods 203 to rotate. The threads of the two threaded rods 203 are opposite. The rotation of the threaded rods 203 drives the threaded block 204 to move. The movement of the threaded block 204 drives the two square blocks 205 to slide outwards on the slide rod 206 at the same time. The slide rod 206 limits the threaded block 204 to prevent the threaded block 204 from rotating with the rotation of the threaded rod 203. The movement of the threaded block 204 drives the two first rectangular frames 4 to move outwards at the same time. When the two threaded blocks 204 move to the outermost end, the first servo motor 201 is turned off. At this point, the pine bed board is placed on the roller 303, with the rightmost end of the pine bed board placed on the rightmost roller 303. The outer wall of the roller 303 is fitted with a rubber sleeve 304. The rubber is soft and elastic, which prevents the roller 303 from scratching or abrading the pine bed board when it comes into contact with the roller 303. The first servo motor 201 is started, and the output shaft of the first servo motor 201 is reversed. The first servo motor 201 moves the two first rectangular frames 4 inward (towards the pine bed board) simultaneously through the above connection method until the outer walls of the two first conveyor belts 5 are pressed against the pine bed board. Then the first servo motor 201 is turned off.

[0018] Cleaning burrs from the front and back edges of the pine bed board: Two second servo motors 7 are started. These two second servo motors 7 are electrically connected to the same battery via wires. A switch on the battery connects to an external remote control. By opening and closing the switch, the second servo motors 7 can be started or stopped simultaneously. The output shafts of the second servo motors 7 rotate, driving the first conveyor belt 5 to rotate. The rotation of the first conveyor belt 5 drives the first sanding belt 6 to rotate. Because the first conveyor belt 5 is pressed against the pine bed board, the rotation of the first sanding belt 6 will remove burrs from the pine bed board. At this time, the operator presses down on the pine bed board... The plate is pushed to the left. When the pine bed plate is pushed, the roller 303 will roll along with the movement of the pine bed plate. This rolling motion helps to reduce resistance and reduce the force required to push. To further explain, the force pushing to the left is opposite to the force of the first conveyor belt 5 rotating. When the pine bed plate moves to the leftmost end, the output shaft of the second servo motor 7 reverses. The operator pushes the pine bed plate to the right. Repeating the above operation can clean the burrs on the front and rear edges of the pine bed plate. After the grinding of both sides is completed, the second servo motor 7 is turned off.

[0019] Cleaning the burrs on both sides of the pine bed board: Move the pine bed board to the left end and press it against the second conveyor belt 10 on the left. Turn off the second servo motor 7 and turn on the external power supply of the third servo motor 9 on the left. Start the third servo motor 9. The output shaft of the third servo motor 9 rotates, causing the second conveyor belt 10 to rotate. The rotation of the second conveyor belt 10 drives the second sanding belt 11 to rotate. The two second conveyor belts 10 limit the front and rear of the pine bed board, and the operator's hand presses down, causing the second sanding belt 11 to clean the burrs on the left edge of the pine bed board in the above manner. Similarly, move the pine bed board to the right side, and the second sanding belt 11 on the right side cleans the burrs on the right edge of the pine bed board in the above manner. The device completes the deburring of all four sides of the pine bed board in one operation (the bed board edges refer to the four sides of the bed board excluding the top and bottom sides). This eliminates the need to clean the two sides of the pine bed board first, followed by a separate process of picking up, placing, and fixing the bed board, thus improving work efficiency. After the burrs on the edges of the pine bed board are cleaned, the two first conveyor belts 5 are moved away from the pine bed board by the first servo motor 201, and the pine bed board is removed. Both sides of the front end of the housing 1 are equipped with maintenance doors, which need to be opened periodically to clean the burr debris inside the housing 1 for the next operation. After turning off all power, the workflow of the pine bed board edge burr cleaning device is completed.
