[0008] When the guide block is pressed against the reel, the two moving rods are moved away from each other and retracted, and the two moving rods are compressed by the movement of the two moving rods. When the reel moves into place, the two first springs are automatically retracted to drive the two moving rods to automatically move back and insert into the circular hole of the circular hole of the reel for fixing. When the reel has finished rewinding the sandpaper, because the side of the moving rod close to the guide block is inclined, the reel is pushed toward the guide block, and the inclined surface of the moving rod is used by the thrust of the reel to drive the two moving rods to move away from each other and retract.

Before rolling up, the rotation of the screw rod is driven by rotating the turntable. Because the arc surface of the screw rod is provided with two reverse threads, the two limit plates move away from or close to each other, and the movement of the two limit plates is driven by the rotation of the screw rod. When the two limit plates move near the two sides of the sandpaper, the turntable is stopped, and finally fixed by inserting the insertion rod on the inner wall of the fixed plate between the tooth blocks on the arc surface of the gear.

[0017] Preferably, the arc surface of the insertion rod is sleeved with a second spring, and two ends of the second spring are fixedly connected to the insertion rod and the fixing plate respectively.

[0022] The utility model provides a winding device for flocking sandpaper production. When the winding sleeve needs to be installed and fixed on the winding shaft to wind the sandpaper, the two positioning plates on the inner wall of the winding sleeve are aligned and inserted into the two positioning grooves on the arc surface of the winding shaft for positioning, so that the winding sleeve moves along the arc surface of the winding shaft. The inner wall of the winding sleeve is provided with a plurality of balls, and the plurality of balls can make the winding sleeve move more conveniently on the arc surface of the winding shaft. When the moving rod on the inner wall of the winding sleeve moves to the position of the guide block, the shape of the guide block is conical. When the winding sleeve continues to move, the moving rod continues to move, and the circular arc surface of the guide block is squeezed to drive the two moving rods to move away from each other and shrink. The movement of the two moving rods drives the compression of two first springs. The first spring is The arc surface of the fixed rod is compressed and stretched, and the fixed rod can prevent the first spring from deforming during the compression and stretching process. When the winding sleeve moves into place, the automatic retraction of the two first springs drives the two moving rods to automatically move back and insert into the circular hole on the arc surface of the winding shaft for fixation. When the winding sleeve finishes winding up the sandpaper, because the side of the moving rod close to the guide block is inclined, by pushing the winding sleeve toward the guide block, the inclined surface of the moving rod is used with the help of the thrust of the winding sleeve to drive the two moving rods to move away from each other and retract. When the two moving rods are moved out of the circular hole, the fixation is released and the winding sleeve can be directly removed. By setting the adjustment structure, the effect of conveniently installing and fixing the winding sleeve on the winding shaft to wind up the sandpaper is achieved.

[0023] When the sandpaper needs to be reeled up, one end of the sandpaper is passed through the rotating shaft and fixed on the reeling sleeve, and then the electric control box is operated to rotate the reeling shaft, and the rotation of the reeling shaft drives the reeling sleeve to rotate to reel up the sandpaper. Before reeling, the rotation of the turntable drives the rotation of the screw rod. Because the arc surface of the screw rod is provided with two opposite threads, the two limit plates are moved away from or close to each other, and the rotation of the screw rod drives the movement of the two limit plates. At the same time, the two limit plates are moved on the arc surface of the limit rod, and the limit rod can prevent the two limit rods from deflecting during the movement. When the two limit plates move to the vicinity of the two sides of the sandpaper, the turntable is stopped. Finally, the insertion rod on the inner wall of the fixed plate is inserted between the tooth blocks on the arc surface of the gear to fix it.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0033] See also Figures 1 to 6 The embodiment of the present invention provides a winding device for flocking sandpaper production, comprising: four universal wheels 1, the upper ends of the four universal wheels 1 are fixedly connected to the same electric control box 2, a winding shaft 5 is installed on one side of the electric control box 2, a rotating shaft 6 is installed on one side of the electric control box 2, a motor 7 is installed on one side of the electric control box 2, an arc surface of the winding shaft 5 is provided with an adjustment structure 3, and the surface of the rotating shaft 6 is provided with an auxiliary structure 4.

[0034] In the embodiments of the present invention, please refer to Figure 3 and Figure 4The adjusting structure 3 includes a circular hole 31, which is opened on the winding shaft 5. The inner wall of the circular hole 31 is slidably connected to two moving rods 32. The two moving rods 32 are fixedly connected to the side away from each other with a first spring 33. The end of the first spring 33 away from the moving rod 32 is fixedly connected to the winding sleeve 34. The side of the winding shaft 5 away from the electric control box 2 is fixedly connected to the guide block 35. When the winding sleeve 34 needs to be installed and fixed on the winding shaft 5 to reel in the sandpaper, the inner wall of the winding sleeve 34 is moved along the arc surface of the winding shaft 5 through the guide block 35. When the moving rod 32 on the inner wall of the winding sleeve 34 moves to the position of the guide block 35, the shape of the guide block 35 is conical. The winding sleeve 34 continues to move, driving the moving rod 32 to continue to move, and the circular arc surface of the guide block 35 is squeezed to drive the two moving rods 32 to move away from each other and shrink. The movement of the two moving rods 32 drives the compression of the two first springs 33. When the winding sleeve 34 moves into place, the automatic retraction of the two first springs 33 drives the two moving rods 32 to automatically move back and insert into the circular hole 31 of the circular arc surface of the winding shaft 5 for fixation. When the winding sleeve 34 completes winding the sandpaper, because the side of the moving rod 32 close to the guide block 35 is inclined, by pushing the winding sleeve 34 toward the guide block 35, the two moving rods 32 are driven by the thrust of the winding sleeve 34 through the inclined surface of the moving rod 32. The moving rods 32 move away from each other and retract. When the two moving rods 32 are removed from the circular holes 31, the fixation is released and the winding sleeve 34 can be directly removed. The inner wall of the winding sleeve 34 is fixedly connected to two positioning plates 36. The arc surface of the winding shaft 5 has two positioning grooves 37. The two positioning grooves 37 are adapted to the two positioning plates 36. When the winding sleeve 34 needs to be installed and fixed on the arc surface of the winding shaft 5, the two positioning plates 36 on the inner wall of the winding sleeve 34 are aligned and inserted into the two positioning grooves 37 on the arc surface of the winding shaft 5 for positioning and movement to prevent deflection during the installation and fixing process. The inner wall of the winding sleeve 34 is slidably connected to a plurality of balls 38. The balls 38 are evenly distributed on the winding sleeve 34. When the winding sleeve 34 is installed and fixed on the arc surface of the winding shaft 5, the winding sleeve 34 needs to be moved on the arc surface of the winding shaft 5. The plurality of balls 38 can reduce the friction between the inner wall of the winding sleeve 34 and the arc surface of the winding shaft 5, making it easier for the winding sleeve 34 to move on the arc surface of the winding shaft 5. The inner wall of the movable rod 32 is slidably connected with the fixed rod 39. The fixed rod 39 and the winding sleeve 34 are fixedly connected. When the first spring 33 is compressed and stretched by the movement of the movable rod 32, the first spring 33 is sleeved on the arc surface of the fixed rod 39 for compression and stretching, which can prevent the first spring 33 from deforming during the compression and stretching process.

[0035] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary structure 4 includes a fixed plate 41, which is fixedly connected to the rotating shaft 6. The inner wall of the fixed plate 41 is rotatably connected to a screw rod 42. The arc surface of the screw rod 42 is provided with two reverse threads. The arc surface of the screw rod 42 is fixedly connected to a gear 43. The screw rod 42 is fixedly connected to a turntable 44 on the side away from the electric control box 2. The arc surface of the screw rod 42 is threadedly connected to two limit plates 45. The inner wall of the fixed plate 41 is slidably connected with an insertion rod 46. When it is necessary to reel up the sandpaper, one end of the sandpaper is passed through the rotating shaft 6 and fixed on the reeling sleeve 34, and then the electric control box 2 is operated to rotate the reeling shaft 5. The rotation of the reeling shaft 5 drives the reeling sleeve 34 to rotate to reel in the sandpaper. Before reeling, the rotation of the turntable 44 drives the screw rod 42 to rotate. Because the arc surface of the screw rod 42 is provided with two reverse threads, the two limit plates 45 are moved away from or close to each other, and the rotation of the screw rod 42 drives the two limit plates 45 to move away from or close to each other. The movement of the plate 45 stops the rotation of the turntable 44 when the two limit plates 45 move to the vicinity of the two sides of the sandpaper, and finally fixes the two limit plates 45 by inserting the insertion rod 46 on the inner wall of the fixing plate 41 between the tooth blocks of the arc surface of the gear 43. The arc surface of the insertion rod 46 is covered with a second spring 47, and the two ends of the second spring 47 are fixedly connected to the insertion rod 46 and the fixing plate 41 respectively. The movement of the insertion rod 46 drives the second spring 47 to be stretched. When the two limit plates 45 are moved into place, the rotation of the screw rod 42 is stopped, and then the insertion rod 46 is released. The automatic retraction of the second spring 47 drives the insertion rod 46 to automatically move back and insert between the tooth blocks of the arc surface of the gear 43 to be fixed. The inner walls of the two limit plates 45 are slidably connected to the same limit rod 48, and the limit rod 48 is fixedly connected to the fixing plate 41. When the two limit plates 45 are driven to move by the rotation of the screw rod 42, the limit rod 48 can prevent the two limit plates 45 from deflecting during the movement;

[0036] The working principle of the winding device for flocking sandpaper production provided by the present invention is as follows: when the winding sleeve 34 needs to be installed and fixed on the winding shaft 5 to wind the sandpaper, the two positioning plates 36 on the inner wall of the winding sleeve 34 are aligned and inserted into the two positioning grooves 37 on the arc surface of the winding shaft 5 for positioning, so that the winding sleeve 34 can move along the arc surface of the winding shaft 5. The inner wall of the winding sleeve 34 is provided with a plurality of balls 38, and the plurality of balls 38 can make the winding sleeve 34 move more conveniently on the arc surface of the winding shaft 5. When the moving rod 32 on the inner wall of the winding sleeve 34 moves to the position of the guide block 35, the shape of the guide block 35 is conical. When the winding sleeve 34 continues to move, it drives the moving rod 32 to continue to move, and the arc surface of the guide block 35 squeezes and drives the two moving rods 32 to move away from each other and retract, and the movement of the two moving rods 32 drives the compression of the two first springs 33, and the first The spring 33 is compressed and stretched on the arc surface of the fixing rod 39, and the fixing rod 39 can prevent the first spring 33 from deforming during the compression and stretching process. When the winding sleeve 34 moves into place, the automatic retraction of the two first springs 33 drives the two moving rods 32 to automatically move back and insert into the circular hole 31 of the arc surface of the winding shaft 5 for fixation. When the winding sleeve 34 has finished winding the sandpaper, because the side of the moving rod 32 close to the guide block 35 is inclined, by pushing the winding sleeve 34 towards the guide block 35, the inclined surface of the moving rod 32 is used by the thrust of the winding sleeve 34 to drive the two moving rods 32 to move away from each other and retract. When the two moving rods 32 are moved out of the circular hole 31, the fixation is released, and the winding sleeve 34 can be directly removed. By setting the adjustment structure 3, the effect of conveniently installing and fixing the winding sleeve 34 on the winding shaft 5 to wind the sandpaper is achieved.

[0037] When the sandpaper needs to be rolled up, one end of the sandpaper is passed through the rotating shaft 6 and fixed on the winding sleeve 34, and then the electric control box 2 is operated to rotate the winding shaft 5. The rotation of the winding shaft 5 drives the winding sleeve 34 to rotate to roll up the sandpaper. Before rolling up, the rotation of the turntable 44 drives the rotation of the screw rod 42. Because the arc surface of the screw rod 42 has two reverse threads, the two limit plates 45 move away from or close to each other. The rotation of the screw rod 42 drives the movement of the two limit plates 45. At the same time, the two limit plates 45 move on the arc surface of the limit rod 48. The limit rod 48 can prevent the two limit rods 48 from deflecting during the movement. When the two limit plates 45 move to the vicinity of the two sides of the sandpaper, the turntable 44 stops rotating. Finally, the insertion rod 46 on the inner wall of the fixed plate 41 is inserted between the tooth blocks on the arc surface of the gear 43 for fixation. By setting the auxiliary structure 4, the sandpaper passing through the rotating shaft 6 can be limited to avoid uneven sandpaper rolled up by the winding sleeve 34.
