Description

Technical Field

[0001] This utility model relates to the technical field of multilayer board processing equipment, and in particular to a device for smoothing the saw cut edges of multilayer boards. Background Technology

[0002] Multi-layer boards are boards made by bonding two or more layers of thin sheets of wood, plastic, or other composite materials together with adhesives under hot or cold pressing conditions. Due to their stable structure, high strength, and high utilization rate, they are widely used in furniture manufacturing, interior decoration, and architectural partitions. In practical applications, multi-layer boards often need to be cut to specific lengths according to usage requirements. Traditional edge-cutting processes generally use ordinary circular saws or band saws. However, because multi-layer boards are made of alternating layers of different materials or fiber directions, defects such as burrs, delamination, and edge chipping are easily generated at the cut during the sawing process, seriously affecting the subsequent edge-banding quality and the appearance of the finished product.

[0003] To address these issues, the current practice is to manually sand or scrape the sawed edges for secondary processing. This method is not only labor-intensive and inefficient, but also highly dependent on operator experience, easily leading to uneven sanding, over-trimming, or damage to the board surface, resulting in a lower product yield. Although some automated equipment has been put into use, it is difficult to accommodate multilayer boards of different widths, exhibiting poor adaptability and inconvenient adjustment, resulting in delayed or incomplete cut processing and affecting the overall smoothness.

[0004] Therefore, it is necessary to design a device for smoothing the cut edges of multi-layer boards. Utility Model Content

[0005] To overcome the shortcomings of low efficiency and unstable quality of manual sanding, and the difficulty of adapting existing automated equipment to multi-layer boards of different widths, resulting in incomplete cut treatment and affecting the smoothing effect, this utility model provides a multi-layer board saw cut smoothing device.

[0006] The technical solution is as follows: A multi-layer board sawing edge smoothing device, including a frame, legs, a controller, a support frame 1, an electric slide rail 1, an electric slider 1, an electric slide rail 2, an electric slider 2, a motor 1, and a grinding roller. Multiple legs are fixedly connected to the bottom of the frame. The controller is installed on the front side of the frame. The support frame 1 is fixedly connected between the front and rear sides of the top of the frame. An electric slide rail 1 is installed at the top inside the support frame 1. An electric slider 1 is slidably installed on the electric slide rail 1. An electric slide rail 2 is installed at the bottom of the electric slider 1. An electric slider 2 is slidably installed on the electric slide rail 2. A motor 1 is installed at the bottom of the electric slider 2. A grinding roller is connected to the output shaft of the motor 1. The electric slide rail 1, electric slider 1, electric slide rail 2, electric slider 2, and motor 1 are all electrically connected to the controller.

[0007] In one embodiment, the device further includes a bidirectional screw, a guide rod, a second motor, and a straightening plate. The bidirectional screw is rotatably connected to the bottom of the frame, and the guide rod is fixedly connected to the bottom of the frame. The second motor is installed on the front side of the frame and is electrically connected to the controller. The output shaft of the second motor is connected to the bidirectional screw. Two straightening plates are threaded onto the bidirectional screw, and both straightening plates are slidably connected to the frame and the guide rod.

[0008] In one embodiment, the device further includes a second support frame, an electric push rod, a support plate, a slide rod, a pressure plate, and springs. The second support frame is fixedly connected between the front and rear sides of the top of the frame. An electric push rod is installed inside the second support frame. The electric push rod is electrically connected to the controller. A support plate is connected to the telescopic rod of the electric push rod. Multiple slide rods are slidably connected inside the support plate. A pressure plate is fixedly connected between the bottoms of the multiple slide rods. Multiple springs are connected between the support plate and the pressure plate.

[0009] In one embodiment, the device further includes a connecting frame, a storage frame, a receiving frame, a connecting pipe, and a pump body. The connecting frame is fixedly connected between the front and rear sides of the right end support leg. The storage frame is slidably connected inside the connecting frame. The receiving frame is fixedly connected to the right side of the frame. The connecting pipe is fixedly connected between the connecting frame and the receiving frame. The pump body is installed on the top of the connecting frame and is electrically connected to the controller.

[0010] In one embodiment, a conveyor roller is also included, with multiple conveyor rollers rotatably connected to the left end of the frame.

[0011] In one embodiment, a scale is also included, with two scales fixedly connected to the right side of the frame.

[0012] Beneficial effects: 1. By cooperating with electric slide rail one and electric slide rail two, the grinding roller can be accurately positioned and moved in the vertical and horizontal directions, effectively covering every area of ​​the cut, adapting to multi-layer boards of different widths, solving the problems of low efficiency and unstable quality of manual grinding, and the difficulty of adapting existing automated equipment to multi-layer boards of different widths, resulting in incomplete cut processing and affecting the smoothing effect.

[0013] 2. This utility model forms an elastic pressing structure by setting an electric push rod, a support plate, a slide rod, a pressure plate and a spring. The spring can be compressed adaptively according to the thickness of the multi-layer board to form a uniform and adjustable pressing force, which can avoid the damage to the board caused by rigid pressing and prevent the board from shifting due to grinding vibration.

[0014] 3. This utility model sets up a storage frame, a collection frame, a connecting pipe, and a pump body. The operation of the pump body generates negative pressure, creating a low-pressure environment inside the connecting frame. Under the action of negative pressure, the dust and fine debris generated during grinding are drawn into the connecting frame with the airflow, and finally drawn into the collection frame for storage through the connecting pipe. This prevents the grinding dust from spreading to the working environment and protects the respiratory health of the operators. Attached Figure Description

Detailed Implementation

[0022] Example: A device for smoothing the cut edges of multi-layer boards, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the assembly includes a frame 1, legs 2, a controller 3, a support frame 4, an electric slide rail 5, an electric slider 6, an electric slide rail 7, an electric slider 8, a motor 9, a grinding roller 10, a conveyor roller 26, and a scale 27. Three legs 2 are welded to the front and rear sides of the bottom of the frame 1. The controller 3 is installed on the front side of the frame 1. A support frame 4 is welded between the front and rear sides of the top of the frame 1. An electric slide rail 5 is installed inside the top of the support frame 4. An electric slider 6 is slidably mounted on the electric slide rail 5 via a groove. Electric slide rail 27 is installed at the bottom of frame 6. Electric slider 28 is slidably installed on electric slide rail 27 via a slide groove. Motor 9 is installed at the bottom of electric slider 28. Grinding roller 10 is connected to the output shaft of motor 9. Electric slide rail 15, electric slider 16, electric slide rail 27, electric slider 28 and motor 19 are all electrically connected to controller 3. Five conveying rollers 26 are rotatably connected to the left end of the frame 1. Two scales 27 are welded to the right side of the frame 1 to facilitate the operator's visual observation of the distance between the right end of the multilayer board extending out of the frame 1.

[0023] like Figure 1 , Figure 3 and Figure 5 As shown, it also includes a bidirectional screw 11, a guide rod 12, a second motor 13, and a straightening plate 14. The bidirectional screw 11 is rotatably connected to the bottom of the frame 1, and the guide rod 12 is welded to the bottom of the frame 1. The second motor 13 is installed on the front side of the frame 1. The second motor 13 is electrically connected to the controller 3. The output shaft of the second motor 13 is connected to the bidirectional screw 11. Two straightening plates 14 are threadedly connected to the bidirectional screw 11 and are symmetrically distributed. The straightening plates 14 are slidably connected to the frame 1 and the guide rod 12 through a sliding groove, which can ensure that the multilayer board is conveyed along the preset center line under the limiting action of the straightening plate 14, and avoid the subsequent grinding from being unable to align the cut due to the conveying deviation.

[0024] like Figure 3 and Figure 6 As shown, it also includes a second support frame 15, an electric push rod 16, a support plate 17, a slide rod 18, a pressure plate 19, and springs 20. The second support frame 15 is welded between the front and rear sides of the top of the frame 1. The electric push rod 16 is installed inside the second support frame 15. The electric push rod 16 is electrically connected to the controller 3. The support plate 17 is connected to the telescopic rod of the electric push rod 16. There are two slide rods 18 symmetrically distributed on the left and right sides of the front and rear sides of the support plate 17 through sliding grooves. The pressure plate 19 is welded between the bottom of the four slide rods 18. Four springs 20 are connected between the support plate 17 and the pressure plate 19. The springs 20 are all sleeved on the outside of the slide rods 18. The reverse elastic force generated by the springs 20 is transmitted to the surface of the multilayer board through the pressure plate 19 to form an elastic clamping force, which ensures that the multilayer board does not shift during the sanding process and avoids the rigid pressure from causing damage or deformation to the surface of the multilayer board.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it also includes a connecting frame 21, a storage frame 22, a receiving frame 23, a connecting pipe 24, and a pump body 25. The connecting frame 21 is welded between the front and rear sides of the right end support 2. The storage frame 22 is slidably connected inside the connecting frame 21 through a sliding groove. The receiving frame 23 is welded to the right side of the frame 1. The connecting pipe 24 is welded between the connecting frame 21 and the receiving frame 23. The pump body 25 is installed on the top of the connecting frame 21 and is electrically connected to the controller 3.

[0026] When this device is needed, the operator first places the sawn plywood on the conveyor roller 26, with the end to be smoothed on the right, and applies a certain pushing force. The conveyor roller 26 drives the plywood to be conveyed to the right horizontally through friction. When the plywood enters the straightening area with the conveyor roller 26, the operator can start the second motor 13 through the controller 3. The output shaft of the second motor 13 rotates, driving the bidirectional screw 11 to rotate, thereby driving the two straightening plates 14 to move towards each other along the guide rod 12 to straighten the plywood. After the straightening is completed, the output shaft of the second motor 13 is reversed, so that the straightening plates 14 move back to their original positions along the guide rod 12. At this time, the plywood is conveyed along the preset center line under the limiting action of the two straightening plates 14. The operator can observe the distance of the right end of the plywood extending out of the frame 1 through the scale 27 until the distance is adjusted to match the position of the plywood to be polished, and then the plywood is no longer pushed.

[0027] Then, the controller 3 controls the electric push rod 16 to extend downward, thereby driving the support plate 17 to descend synchronously. The multiple sliding rods 18 inside it move down accordingly. The pressure plate 19 contacts the surface of the multilayer board in advance. When it continues to descend, the sliding rods 18 slide upward in the support plate 17. The reverse elastic force generated by the spring 20 is transmitted to the surface of the multilayer board through the pressure plate 19 to form an elastic clamping force. Next, the electric slider 28 is driven to move left and right along the electric slide rail 27 to adjust the horizontal position of the grinding roller 10, so that the grinding roller 10 is initially aligned with the cut to be processed. After the adjustment is completed, the controller 3 starts the motor 9 and the pump body 25. The output shaft of the motor 9 rotates the grinding roller 10 at high speed and controls the electric slide rail 5 to slowly drive the electric slider 6 to move back and forth, ensuring that the grinding roller 10 performs a comprehensive and uniform smoothing treatment on the cut, removing burrs and chipped edges. During the grinding process, the pump body 25 generates negative pressure, creating a low-pressure environment inside the connecting frame 21. The dust and fine debris generated during grinding are sucked into the connecting frame 21 by the airflow under the negative pressure, and finally sucked into the storage frame 23 through the connecting pipe 24 for storage.

[0028] After grinding, the controller 3 controls the extension rod 16 to retract, which drives the support plate 17 and pressure plate 19 to rise and reset. The electric slider 6 is stopped and the motor 9 and pump 25 are turned off, so the trimmed multilayer board can be taken out. When processing the next multilayer board, the above operation is repeated. After all multilayer boards have been trimmed, the operator can pull out the debris storage box 22, clean the debris inside, and push it back, thus completing the use of this device.
