Description

Technical Field

[0001] The utility model belongs to the field of plywood surface polishing, and particularly relates to an adjustable plywood surface polishing device. Background Technique

[0002] Plywood is a three-layer or multi-layer plate material made by slicing wood segments into veneers or planing wood squares into thin woods and then gluing them with adhesives. The produced plywood needs to go through a polishing step before it can be used.

[0003] Some devices for plywood surface polishing have been specifically developed in the prior art. For example, the Chinese patent with the publication number "CN213795904U" discloses "a plywood surface polishing device". The plywood is placed between two clamping plates on the back of the T-shaped push plate. By rotating the rotating wheel, the second screw rotates in the T-shaped push plate, and two sliders move towards each other under the screw thrust, driving the two clamping plates to clamp the plywood. Then, the second motor is controlled to rotate, driving the first screw to rotate, so that the T-shaped push plate moves backward under the screw thrust, pushing the plywood towards the polishing roller, making the plywood move linearly past the lower part of the polishing roller. And by driving the rotating rod to rotate in the groove through the first motor, the polishing roller can be rotated, thereby polishing the plywood passing below. The two clamping plates can move left and right to adapt to plywood of different widths, realizing the adaptive fixation of the plywood. The entire polishing process is also automatically completed, achieving the purpose of convenient use.

[0004] Although the plywood can be polished by rotating the rotating wheel to make the second screw rotate in the T-shaped push plate, the two sliders move towards each other under the screw thrust, and the polishing roller rotates, so as to polish the plywood passing below. The two clamping plates can move left and right to adapt to plywood of different widths, realizing the adaptive fixation of the plywood. The entire polishing process is also automatically completed, achieving the purpose of convenient use. However, when using it, after polishing the surface of the plywood, it is necessary to turn the plywood over to polish the back surface of the plywood. When turning the plywood over, the staff needs to manually pull out the plywood and then turn it over. This will increase the workload of the staff, and the work efficiency will also be reduced under the operation of manual turning, and it cannot effectively reduce the workload of the staff and improve the efficiency of the device. Summary of the Utility Model

On one side of one of the support rods, an internal thread block is integrally formed. Inside the internal thread block, a screw rod is threadedly connected. One end of the screw rod is fixedly connected to the output shaft of a third motor. The end of the screw rod away from the third motor is rotatably installed with a fixed block. On the inner sides of the support rods on both sides of the bottom plate close to each other, limit plates are fixedly installed. At both ends of the surface of the bottom plate, clamping plates are fixedly installed. At one end of the clamping plate, an electric telescopic rod two is fixedly installed. The end of the electric telescopic rod two away from the clamping plate is fixedly installed with a mounting plate. On one end of one of the mounting plates away from the electric telescopic rod two, a second motor is fixedly installed.

[0008] As a preferred technical solution, rectangular grooves are opened at the positions of the support rods on both sides inside the bottom plate. Inside the rectangular grooves, cylindrical rods are fixedly installed. At the bottoms of both support rods, connection ports are opened.

[0013] As a preferred technical solution, a second bearing is fixedly installed on one side of one of the clamping plates, and the output shaft of the second electric telescopic rod is fixedly installed on the inner ring of the second bearing.

[0014] As a preferred technical solution, a support seat is fixedly installed at the bottom of the second motor, one end of the support seat away from the second motor is fixedly installed on one side of the bottom plate, and support legs are fixedly installed at the four corners of the bottom of the bottom plate.

[0015] In summary, the main beneficial effects of the present utility model are as follows:

[0016] First, when in use, start the electric telescopic rod three inside the rectangular block to move the placement plate fixedly installed at the upper end of the output shaft of the electric telescopic rod three to the upper end of the bottom plate, and then place the plywood body to be polished on the upper end of the placement plate. The placement plate can effectively limit the plywood body. There are clamping plates clamped at both ends of the plywood body, and one end of the clamping plate away from the plywood body is fixedly installed with an electric telescopic rod two. Under the push of the electric telescopic rod two, the two ends of the plywood body can be effectively clamped. One end of one of the clamping plates is fixedly installed with an anti-slip pad, which can increase the friction with both ends of the plywood body and improve the fixing effect. At this time, one end of one of the electric telescopic rods two is fixedly installed with a second motor. The rotation of the second motor can drive the plywood body to rotate, which can effectively solve the problem of manually turning over the plywood body, improve the quality and efficiency of the work. When the second motor drives the plywood body to rotate, the electric telescopic rod three will drive the placement plate to retract into the rectangular block, which can avoid the plywood body touching the placement plate when rotating and causing damage to the plywood body, effectively reducing the workload of workers.

[0017] Second, in order to prevent the plywood body from moving when the polishing roller polishes the plywood body, limit plates are fixedly installed on both sides of the plywood body at the upper end of the base. Since one end of the limit plate away from the plywood body is fixedly installed with an electric telescopic rod one, the plywood body will not contact the limit plate when it is placed on the surface of the placement plate. After the plywood body is placed, the electric telescopic rod one can be controlled to push the limit plate to clamp both sides of the plywood body, so that the plywood body will not move during polishing, effectively improving the polishing quality. An anti-slip pad is fixedly installed on one side of the limit plate, so that both sides of the plywood body can be fixed more firmly.

[0018] Thirdly, since a suction fan is fixedly installed at the upper end of the movable plate, and the suction fan can effectively absorb the debris generated by the polishing roller, it can effectively maintain the cleanliness of the polishing roller. The slide bars fixedly installed on both sides of the suction fan can effectively limit the movable plate and prevent the movable plate from shifting during movement, thereby improving the movement effect of the movable plate. An internal thread block is integrally formed at one end of the support rod. The third motor drives the screw rod to rotate, and the screw rod threadedly connected inside the internal thread block can effectively drive the support rod to move, facilitating the polishing and grinding of the plywood body.

[0031] Principle of use and advantages: When in use, start the electric telescopic rod three 27 inside the rectangular block 21 to move the placement plate 14 fixedly installed at the upper end of the output shaft of the electric telescopic rod three 27 to the upper end of the bottom plate 10. Then place the plywood body 11 to be polished on the upper end of the placement plate 14. The placement plate 14 can effectively limit the plywood body 11. Clamping plates 16 are clamped at both ends of the plywood body 11. One end of the clamping plate 16 away from the plywood body 11 is fixedly installed with an electric telescopic rod two 17. Under the push of the electric telescopic rod two 17, the two ends of the plywood body 11 can be effectively clamped. One end of the clamping plate 16 is fixedly installed with an anti-slip pad 29, which can increase the friction with both ends of the plywood body 11 and improve the fixing effect. At this time, one end of one of the electric telescopic rods two 17 is fixedly installed with a second motor 12. The rotation of the second motor 12 can drive the plywood body 11 to rotate, which can effectively solve the problem of manually turning over the plywood body 11 and improve the quality and efficiency of work. When the second motor 12 drives the plywood body 11 to rotate, the electric telescopic rod three 27 will drive the placement plate 14 to retract into the rectangular block 21, which can prevent the plywood body 11 from touching the placement plate 14 during rotation and causing damage to the plywood body 11, effectively reducing the workload of workers. In order to prevent the plywood body 11 from moving when the polishing roller 28 polishes the plywood body 11, limit plates 20 are fixedly installed on both sides of the plywood body 11 at the upper end of the base. Since one end of the limit plate 20 away from the plywood body 11 is fixedly installed with an electric telescopic rod one 6, the plywood body 11 will not contact the limit plate 20 when it is placed on the surface of the placement plate 14. After the plywood body 11 is placed, the electric telescopic rod one 6 can be controlled to push the limit plate 20 to clamp both sides of the plywood body 11, so that the plywood body 11 will not move during polishing, effectively improving the polishing quality. An anti-slip pad 29 is fixedly installed on one side of the limit plate 20, so that both sides of the plywood body 11 can be fixed more firmly. Since a suction fan 18 is fixedly installed at the upper end of the movable plate 19, the suction fan 18 can effectively absorb the debris generated by the polishing roller 28, effectively maintaining the cleanliness of the polishing roller 28. The slide rods 3 fixedly installed on both sides of the suction fan 18 can effectively limit the movable plate 19 and prevent the movable plate 19 from shifting during movement, improving the movement effect of the movable plate 19. An internal thread block 22 is integrally formed at one end of the support rod 5. The third motor 31 drives the screw rod 25 to rotate. The rotation of the screw rod 25 threadedly connected inside the internal thread block 22 can effectively drive the support rod 5 to move, facilitating the polishing and grinding of the plywood body 11.
