[0014] Beneficial Effects

[0015] The utility model provides a fast hot winding structure for sandpaper production. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The rapid hot winding structure for sandpaper production has clamping components on both sides. When it is necessary to clamp winding drums of different diameters, the winding drum is first lifted to a suitable position, and then the inner wall of the winding drum is inserted into the outer wall of the rotating drum. Then, the first electric push rod is turned on. The first electric push rod drives the moving top block to move. During the movement, the moving top block contacts the moving block on the inner wall of the rotating drum. As the moving top block moves, the moving block is lifted up by the moving top block and moves outward. The moving block drives the arc-shaped top plate to move toward the inner wall of the winding drum through the sliding rod. The spring will be stretched until the four arc-shaped top plates contact the inner wall of the winding drum and exert a certain pressure. At this time, the winding drum can be fixed and clamped. By controlling the movement of the arc-shaped top plates, winding drums of different diameters can be fixed and clamped. When the winding drum needs to be removed, it is only necessary to open the first electric push rod again. The first electric push rod drives the moving top block to retract. At this time, the moving block loses the support of the moving top block, and the slide bar drives the arc-shaped top plate away from the inner wall of the winding drum under the action of the spring elastic force, thereby realizing the quick removal of the winding drum.

[0017] (2) The rapid hot winding structure used for sandpaper production can move the rotating clamping mechanism on one side through the moving slide and the moving block, so that winding rollers of different lengths can be installed and clamped. A second electric push rod and an arc-shaped support plate are provided, so that the winding roller can be placed on the arc-shaped support plate first, and then the second electric push rod is turned on to make the winding roller rise and fall to a suitable height, thereby facilitating the clamping of the winding roller.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides two technical solutions:

[0027] Figure 1-Figure 6 The first embodiment is shown: a fast hot winding structure for sandpaper production, comprising a base 1, a movable chute 2 is provided at the top of the base 1, a movable plate 3 is slidably connected to the inner wall of the movable chute 2, and the distance between the two rotating clamping mechanisms 4 can be adjusted by setting the movable chute 2 and the movable plate 3, so that winding drums of different lengths can be clamped, and the rotating clamping mechanisms 4 are respectively provided at the top of the movable plate 3 and the base 1 for clamping and rotating the winding drum, and the rotating clamping mechanism 4 includes:

[0028] The rotating assembly 41 includes a first vertical plate 411, a rotating ring 414 is rotatably mounted on the outer wall of the first vertical plate 411, and an outer gear ring 415 is fixedly sleeved on the outer wall of the rotating ring 414;

[0029] The clamping assembly 42 includes a second vertical plate 421, and a first electric push rod 422 is fixedly installed on the outer wall of the second vertical plate 421, and a movable top block 423 is fixedly installed on the output end of the first electric push rod 422. The first electric push rod 422 is a prior art, which can drive the movable top block 423 to extend and retract, and the first electric push rod 422 does not contact the rotating cylinder 424. The clamping assembly 42 also includes a rotating cylinder 424, which is fixedly installed on the outer wall of the outer gear ring 415. When the outer gear ring 415 rotates, it will drive the rotating cylinder 424 to rotate. The outer wall of the rotating cylinder 424 is provided with four arc grooves 425, and the inner walls of the four arc grooves 425 are movably inserted with sliding rods 428, and one end of the four sliding rods 428 is fixedly installed with an arc top plate 424. 27. The outer wall of the arc-shaped top plate 427 is provided with an anti-skid groove to improve the friction of the arc-shaped top plate 427 against the inner wall of the winding drum. The other ends of the four sliding rods 428 pass through the inner wall of the arc-shaped groove 425 and are respectively fixed with moving blocks 429. The moving blocks 429 and the moving top block 423 are set to suitable shapes and angles so that the moving top block 423 can push the moving block 429 to move. The outer walls of the four moving blocks 429 are provided with mounting grooves 430, and the inner walls of the four mounting grooves 430 are rotatably installed with three rollers 431. The roller 431 will first contact the movable top block 423, so it can reduce the friction force of the movable block 429 rotating on the surface of the movable top block 423. The outer walls of the four sliding rods 428 are all sleeved with springs 426, one end of the spring 426 is fixedly connected to the arc-shaped top plate 427, and the other end of the spring 426 is fixedly connected to the inner wall of the arc-shaped groove 425. When the sliding rod 428 drives the arc-shaped top plate 427 to move, the spring 426 will be stretched and store elastic potential energy. When the movable top block 423 is moved away, the spring 426 will drive the arc-shaped top plate 427 away from the inner wall of the winding drum, thereby realizing the rapid disassembly of the winding drum.

The motor 412 can drive the gear 413 to rotate, and the gear 413 in turn drives the outer gear ring 415 to rotate. A square groove 5 is provided at the top of the base 1, and a second electric push rod 6 is fixedly installed at the bottom of the inner wall of the square groove 5. The setting of the square groove 5 can make the arc support plate 7 drop to a lower height to prevent the arc support plate 7 from affecting the winding drum to wind up the sandpaper. The output end of the second electric push rod 6 is fixedly installed with the arc support plate 7. The winding roller is placed on the arc-shaped support plate 7. At this time, the second electric push rod 6 is turned on to lift the winding roller to a suitable height, thereby improving the stability of the winding roller during installation. A first vertical plate 411 and a second vertical plate 421 in a set of rotating clamping mechanisms 4 are fixedly connected to the base 1, and a first vertical plate 411 and a second vertical plate 421 in a set of rotating clamping mechanisms 4 are fixedly connected to the movable plate 3.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, first, according to the length of the winding roller to be installed, the rotating clamping mechanism 4 on one side is moved to facilitate the installation of the winding roller, and then the winding roller is placed on the arc-shaped support plate 7. At this time, the second electric push rod 6 is turned on to lift the winding roller to a suitable height, which improves the stability of the winding roller during installation. At this time, the inner wall of one end of the winding roller is first inserted into the outer wall of the rotating cylinder 424 on the other side, and then the rotating cylinder 424 on one side is moved so that the rotating cylinder 424 is inserted into the inner wall of the other side of the winding roller. At this time, the first electric push rods 422 on both sides are turned on. 2 drives the movable top block 423 to move. During the movement, the movable top block 423 will contact the movable block 429 on the inner wall of the rotating cylinder 424. As the movable top block 423 moves, the movable block 429 will be lifted up by the movable top block 423 and move outward. The movable block 429 will drive the arc top plate 427 to move toward the inner wall of the winding cylinder through the sliding rod 428. At this time, the spring 426 will be stretched until the four arc top plates 427 contact the inner wall of the winding cylinder and apply a certain pressure. At this time, the winding cylinder can be fixed and clamped. By controlling the movement of the arc top plate 427, different The winding drum of the diameter is fixedly clamped. When the winding drum is installed, the second electric push rod 6 is turned on to make the arc support plate 7 drop to prevent the arc support plate 7 from affecting the winding of the sandpaper. Then the two motors 412 are turned on at the same time. The two motors 412 drive the two gears 413 to rotate. The two gears 413 then drive the outer gear ring 415 and the rotating drum 424 to rotate. Since the arc top plate 427 clamps the winding drum, the winding drum will rotate with the rotation of the rotating drum 424. At this time, the sandpaper can be wound around the outer wall of the winding drum to be wound. The rotating drum 424 rotates During the process, the moving block 429 will be driven to rotate on the surface of the moving top block 423, and the moving block 429 is provided with a group of rollers 431, so the friction of the moving block 429 rotating on the surface of the moving top block 423 can be reduced. When the winding drum needs to be removed, it is only necessary to turn on the first electric push rod 422 again, and the first electric push rod 422 drives the moving top block 423 to retract. At this time, the moving block 429 loses the support of the moving top block 423, and the slide bar 428, under the action of the elastic force of the spring 426, drives the arc-shaped top plate 427 away from the inner wall of the winding drum, thereby realizing the rapid removal of the winding drum.
