Description

Technical Field

[0001] This utility model relates to the field of wood flooring processing technology, and more specifically, to an edge grinding device for wood flooring processing. Background Technology

[0002] The primary reason for edge grinding during wood flooring processing is to improve the aesthetics and safety of the flooring. Edge grinding removes burrs and irregularities from the wood edges, ensuring smooth edges on each plank and preventing scratches or dents during installation and use. Furthermore, edge grinding allows for tighter joints, reducing gaps and improving overall stability and durability. Finally, edge grinding creates a more harmonious visual effect, enhancing the overall aesthetic appeal of the flooring.

[0003] However, in the current technology, when sanding the edges of wood flooring, workers usually use hand-held sanding equipment. During this process, workers can only rely on experience to control the sanding force, which can easily lead to problems such as excessive or insufficient sanding force. Excessive sanding force can cause dents, scratches, or wear on the surface of the wood flooring, or even damage the structure of the wood. Insufficient sanding force will not be able to effectively remove burrs and irregular parts. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a grinding device for wood flooring processing. This solves the technical problem that in the existing technology, workers can only control the grinding force by relying on experience, which leads to the grinding force being too large or too small, affecting the grinding effect of the wood flooring.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding device for wood flooring processing, comprising a body, a ball screw is provided inside the body, a first electric telescopic rod is fixedly connected to the outer wall of the slider of the ball screw, a first motor is fixedly connected to the top of the body, the main shaft of the first motor passes through the outer wall of the body and is fixedly connected to the end of the ball screw inside, a second electric telescopic rod is fixedly connected to the inner wall of the body, a push plate is fixedly connected to the other end of the second electric telescopic rod, a U-shaped frame is fixedly connected to the inner wall of the body, a support frame is fixedly connected to the other end of the first electric telescopic rod, and a grinding mechanism for grinding the edges of wood flooring is provided on the support frame.

[0006] The sanding mechanism includes a transmission roller rotatably connected to the inner surface of the support frame. A second motor is fixedly connected to the outer wall of the support frame. The main shaft of the second motor passes through the support frame and is synchronously connected to the transmission roller. Symmetrically arranged sliding grooves are provided on the inner surface of the support frame. The sliding grooves are semi-circular in structure. Adjusting blocks are slidably connected to the inner walls of the sliding grooves. A sanding roller is rotatably connected to one side of the opposite side of the adjusting blocks. A sanding belt is sleeved between the outer wall of the sanding roller and the outer wall of the transmission roller. A force control component is provided inside the sliding groove to control the sanding force of the sanding belt on the wood floor.

[0007] The force control component includes an adjusting tube with a shape corresponding to the slide groove. The adjusting tube is telescopic, with one end fixedly connected to the inner end wall of the slide groove and the other end fixedly connected to the outer wall of the adjusting block. A pressure column is provided on the outer wall of the adjusting tube, with one end penetrating the outer wall of the adjusting tube and slidingly connected to the inner wall of the penetrating portion. The end of the pressure column penetrating into the adjusting tube forms a "V" shape. A spring is provided inside the adjusting tube, with one end of the spring welded to the end of the pressure column inside the adjusting tube. A return hole is provided at the end of the pressure column, and a sealing plate is fixedly connected to the end of the pressure column inside the adjusting tube. The sealing sheet covers and seals the return hole, and can be lifted when external fluid enters the regulating pipe through the return hole. The wood flooring to be sanded is placed on the U-shaped frame, and the push plate is moved by the second electric telescopic rod to clamp and fix the wood flooring. The first motor drives the first electric telescopic rod to move up and down through the ball screw, so that the first electric telescopic rod itself can drive the support frame to move up and down and left and right. During the movement of the support frame, the sanding mechanism on the support frame sands the edges of the wood flooring. It should be noted that during the sanding process, the force control component will automatically control the sanding force when sanding the wood flooring, so as to prevent the sanding force from being too large or too small during the sanding process, which would affect the edge sanding effect.

[0008] Preferably, the adjusting tube has a threaded rod inside, one end of which is welded to the other end of the spring, and the other end of which passes through the interior of the adjusting tube and the slide groove to the exterior of the support frame and is threaded to both. By controlling the rotation of the threaded rod, the length of the threaded rod inside the adjusting tube changes, thereby changing the sanding force controlled by the force control component. This allows the sanding mechanism to perform precise sanding according to different types of wood flooring, thus improving the edge sanding effect on the wood flooring.

[0009] Preferably, the regulating pipe is filled with hydraulic oil, and an oil reservoir is fixedly connected inside the support frame. The oil reservoir is penetrated by the pressure column, and the inner wall of the oil reservoir where the pressure column penetrates is slidably connected to the outer wall of the pressure column. Since the force control component controls the polishing force of the polishing mechanism by squeezing the medium, and hydraulic oil cannot be compressed, the accuracy of the force control component in controlling the polishing force is improved, thereby increasing the edge polishing effect on the wood floor. The oil reservoir can recycle and reuse the hydraulic oil, thus preventing waste.

[0010] Preferably, the two ends of the sanding roller gradually taper towards the middle to form a waist shape, and the sanding roller is made of rubber. The waist shape formed by the sanding roller allows it to squeeze the sanding belt to fit the edge of the wood floor when it pushes the sanding belt into contact with the edge of the wood floor, thus achieving a wrapping and sanding effect on the edge of the wood floor, thereby increasing the effect of sanding the edge of the wood floor. In addition, the rubber sanding roller can shrink when it squeezes the wood floor, thereby increasing the wrapping and sanding effect of the sanding belt on the wood floor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model comprises a machine body, a ball screw, a first electric telescopic rod, a first motor, a second electric telescopic rod, a push plate, a U-shaped frame, a support frame, and a sanding mechanism. The wood flooring to be sanded is placed on the U-shaped frame. The second electric telescopic rod drives the push plate to move, clamping and fixing the wood flooring. The first motor, via the ball screw, drives the first electric telescopic rod to move up and down, thereby enabling the first electric telescopic rod to move the support frame up and down and left and right. During this movement, the sanding mechanism on the support frame sands the edges of the wood flooring. It is important to note that during sanding, the force control component automatically controls the sanding force to prevent excessive or insufficient sanding force from affecting the edge sanding effect.

[0013] 2. In this utility model, by controlling the rotation of the threaded rod, the length of the threaded rod inside the adjusting tube is changed, thereby changing the sanding force controlled by the force control component. This allows the sanding mechanism to perform precise sanding according to different types of wood flooring, thus increasing the effect of sanding the edges of the wood flooring.

[0014] 3. The waist-shaped shape of the sanding roller in this utility model allows it to squeeze the sanding belt to fit the edge of the wood floor when it contacts the edge of the wood floor, thus achieving a wrapping and sanding effect on the edge of the wood floor, thereby increasing the effect of sanding the edge of the wood floor. In addition, the rubber material of the sanding roller can shrink when it squeezes the wood floor, thereby increasing the wrapping and sanding effect of the sanding belt on the wood floor.

[0024] like Figures 1 to 7 As shown, this utility model relates to an edge-grinding device for wood flooring processing, comprising a body 1, a ball screw 2 disposed inside the body 1, a first electric telescopic rod 3 fixedly connected to the outer wall of the slider of the ball screw 2, a first motor 4 fixedly connected to the top of the body 1, the main shaft of the first motor 4 passing through the outer wall of the body 1 to its interior and fixedly connected to the end of the ball screw 2, a second electric telescopic rod 5 fixedly connected to the inner wall of the body 1, a push plate 6 fixedly connected to the other end of the second electric telescopic rod 5, a U-shaped frame 7 fixedly connected to the inner wall of the body 1, a support frame 8 fixedly connected to the other end of the first electric telescopic rod 3, and a grinding mechanism for grinding the edges of wood flooring disposed on the support frame 8.

[0025] The sanding mechanism includes a transmission roller 9, which is rotatably connected to the inner surface of the support frame 8. A second motor 10 is fixedly connected to the outer wall of the support frame 8. The main shaft of the second motor 10 passes through the support frame 8 and is synchronously connected to the transmission roller 9. The inner surface of the support frame 8 is provided with symmetrically arranged sliding grooves 11. The sliding grooves 11 have a semi-circular structure. Adjusting blocks 12 are slidably connected to the inner wall of each sliding groove 11. A sanding roller 13 is rotatably connected to one side of the opposing side of the adjusting blocks 12. A sanding belt 14 is sleeved between the outer wall of the sanding roller 13 and the outer wall of the transmission roller 9. A force control component is provided inside the sliding groove 11 to control the sanding force of the sanding belt 14 on the wood floor.

[0026] The force control component includes an adjusting tube 15, whose shape corresponds to the slide groove 11. The adjusting tube 15 is a telescopic structure. One end of the adjusting tube 15 is fixedly connected to the inner end wall of the slide groove 11, and the other end of the adjusting tube 15 is fixedly connected to the outer wall of the adjusting block 12. A pressure column 16 is provided on the outer wall of the adjusting tube 15. One end of the pressure column 16 penetrates the outer wall of the adjusting tube 15 and slides in connection with the inner wall of the penetration point. The end of the pressure column 16 penetrating into the adjusting tube 15 forms a "V" shape. A spring 17 is provided inside the adjusting tube 15. One end of the spring 17 is welded to the end of the pressure column 16 located inside the adjusting tube 15. A return hole 18 is provided at the end of the pressure column 16, through which it passes. A sealing plate 19 is fixedly connected to the end of the pressure column 16 located inside the adjusting tube 15. The sealing plate 19 covers and seals the return hole 18, and the sealing plate 19 can be lifted when external fluid enters the regulating pipe 15 through the return hole 18. The wood flooring to be sanded is placed on the U-shaped frame 7, and the push plate 6 is moved by the second electric telescopic rod 5 to clamp and fix the wood flooring. The first motor 4 drives the first electric telescopic rod 3 to move up and down through the ball screw 2, so that the first electric telescopic rod 3 can drive the support frame 8 to move up and down and left and right. During the movement of the support frame 8, the sanding mechanism on the support frame 8 sands the edge of the wood flooring. It should be noted that during the sanding process, the force control component will automatically control the sanding force when sanding the wood flooring, so as to prevent the sanding force from being too large or too small during the sanding process, which would affect the edge sanding effect.

[0027] Furthermore, a threaded rod 20 is provided inside the adjusting tube 15. One end of the threaded rod 20 is welded to the other end of the spring 17, and the other end of the threaded rod 20 passes through the interior of the adjusting tube 15 and the slide groove 11 to the exterior of the support frame 8 and is threaded to both. By controlling the rotation of the threaded rod 20, the length of the threaded rod 20 inside the adjusting tube 15 is changed, thereby changing the sanding force controlled by the force control component. This allows the sanding mechanism to perform precise sanding according to different types of wood flooring, thereby increasing the effect of sanding the edges of the wood flooring.

[0028] Furthermore, the regulating pipe 15 is filled with hydraulic oil, and an oil storage box 21 is fixedly connected inside the support frame 8. The oil storage box 21 is penetrated by the pressure column 16, and the inner wall of the oil storage box 21 at the penetration point of the pressure column 16 is slidably connected to the outer wall of the pressure column 16. Since the force control component controls the grinding force of the grinding mechanism by squeezing the medium, and the hydraulic oil cannot be compressed, the accuracy of the force control component in controlling the grinding force is improved, thereby increasing the edge grinding effect on the wood floor. The oil storage box 21 can recycle and reuse the hydraulic oil, thereby preventing waste.

[0029] Furthermore, the two ends of the sanding roller 13 gradually taper towards the middle to form a waist shape, and the sanding roller 13 is made of rubber. The waist shape formed by the sanding roller 13 allows it to squeeze the sanding belt 14 to fit against the edge of the wood floor when it pushes the sanding belt 14 to contact the edge of the wood floor, thus achieving a wrapping sanding effect on the edge of the wood floor, thereby increasing the effect of sanding the edge of the wood floor. In addition, the rubber sanding roller 13 can shrink when it squeezes the wood floor, thereby increasing the wrapping sanding effect of the sanding belt 14 on the wood floor.

[0030] Working principle: This embodiment provides a grinding device for wood flooring processing. In use, the wood flooring to be ground is placed on the U-shaped frame 7. Then, the second electric telescopic rod 5 extends and drives the push plate 6 to move towards the wood flooring, so that the push plate 6 and the U-shaped frame 7 clamp and fix the wood flooring. Then, the first motor 4 runs and causes the ball screw 2 to run, which drives the first electric telescopic rod 3 to move up and down. The extension of the first electric telescopic rod 3 drives the support frame 8 to move towards the edge of the wood flooring. The second motor 10 runs and drives the transmission roller 9 to rotate. The rotation of the transmission roller 9 drives the grinding belt 14 and the grinding roller 13 to rotate, so that the grinding roller 13 squeezes the grinding belt 14 to fit against the edge of the wood flooring for rotational grinding.

[0031] As the sanding belt 14 adheres to the edge of the wood flooring, the sanding roller 13 presses against the wood flooring through the sanding belt 14. The reaction force on the sanding roller 13 causes it to move along with the adjusting block 12 within the slide groove 11. The movement of the adjusting block 12 within the slide groove 11 pushes the adjusting tube 15, causing it to shorten. During this shortening process, the adjusting tube 15 pushes the internal hydraulic oil, causing the hydraulic oil to push the pressure column 16 to move. As the pressure column 16 moves, it pulls on the spring 17. When the squeezing force on the adjusting tube 15 exceeds the stretching force on the spring 17, the hydraulic pressure inside the adjusting tube 15 decreases after the pressure column 16 moves. Oil enters the oil reservoir 21 through the gap between the pressure column 16 and the regulating tube 15, thereby controlling the force required to shorten the regulating tube 15 and controlling the reaction force generated by the regulating block 12 squeezing the regulating tube 15 to shorten it. Since the sanding roller 13 pushes the regulating block 12 to move, the reaction force on the regulating block 12 will be transmitted to the sanding roller 13. As a result, when the force of the sanding roller 13 squeezing the sanding belt 14 against the edge of the wood floor is too large, the regulating tube 15 will shorten, thereby controlling the force of the sanding roller 13 squeezing the sanding belt 14 against the edge of the wood floor, enabling precise sanding of the wood floor edge and increasing the edge sanding effect of the wood floor.

[0032] Rotating the threaded rod 20 can change the length of the threaded rod 20 inside the adjusting tube 15, thereby causing the threaded rod 20 to drive the spring 17 to move, which in turn changes the force of the pressure column 16 pulling the spring 17 to extend, thereby adjusting the sanding force when the sanding roller 13 squeezes the sanding belt 14 to sand the edge of the wood floor.

[0033] After the wood flooring is sanded, the support frame 8 moves the sanding roller 13 away from the edge of the wood flooring. Since the slide groove 11 is a semi-circular structure, the sanding roller 13 will move the adjusting block 12 back to its original position under its own weight. This causes the adjusting block 12 to pull the adjusting tube 15 back to its original position and extend. This allows the adjusting tube 15 to draw the hydraulic oil inside the oil reservoir 21 back into the interior through the return hole 18. The sealing plate 19 will be lifted by the hydraulic oil, thus not affecting the return of the hydraulic oil. This allows the sanding roller 13 to return to its original position in preparation for the next edge sanding of the wood flooring.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
