Technical Field

[0001] The utility model relates to the field of sandpaper cutting, in particular to a fixed-distance cutting device for sandpaper processing. Background Art

[0002] The fixed-distance cutting equipment for sandpaper processing is composed of a cutting machine, a support frame, a sandpaper roll and accessories, and is more common in daily life.

[0003] The existing technology such as announcement number: CN212953433U relates to the technical field of sandpaper cutting device, in particular to an automatic sandpaper cutting device, comprising a cutting device main body, a feeding frame, a lower feed roller, an upper feed roller and a movable cutter, wherein a feeding frame is installed on one side of the cutting device main body, a feeding rod is provided on the top of the feeding frame, a sandpaper roll is sleeved on the feeding rod, and a sandpaper roll is located at both ends of the sandpaper roll. Limit rings are installed on the feeding rod. A receiving table is installed on the other side of the cutting device main body, and a controller is installed on the base surface of the cutting device main body. A motor support plate is provided on one side of the controller, and a motor is installed on the top of the motor support plate. A guide roller, a lower feed roller and a fixed cutter are sequentially installed in the cutting device main body from left to right. The overall device controls the rotation speed of the motor through the controller, thereby controlling the conveying speed of the sandpaper, and can cut the sandpaper to a fixed length according to production requirements. It has a high degree of automation, improves production efficiency, and has certain promotion value.

[0004] The inventor found in daily use that when using the sandpaper processing fixed-distance cutting equipment, the sandpaper roll needs to be put on the connecting rod for fixing, and then the sandpaper on the sandpaper roll needs to be cut. However, when the sandpaper roll is installed and fixed on the connecting rod, various parts need to be used to position and fix the sandpaper roll and the connecting rod, which makes the operation cumbersome and wastes time.

[0005] Therefore, it is necessary to provide a new sandpaper processing fixed-distance cutting device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a sandpaper processing fixed-distance cutting device.

[0007] The cam is fixedly mounted on the support frame, and the cam is connected to the support frame by a toothed connection, and the toothed connection is fixedly mounted on the support frame.

[0008] The effect achieved by the above components is: when sandpaper needs to be cut, the sandpaper roll is put on the arc surface of the connecting rod, and then the connecting rod is installed on the support frame, and then the rotation of the first motor output end drives the rotation of the first screw, and the rotation of the first screw drives the movement of the adjusting plate, the second motor, the screw rod, the connecting plate and the clamping plate. When the upper end of the clamping plate moves to abut the arc surface of the connecting rod, it stops rotating, and then the rotation of the screw rod is driven to rotate by the rotation of the second motor output end. Because the arc surface of the screw rod has two reverse threads, the two clamping plates move away from or close to each other, and the two clamping plates are driven to move toward the position of the sandpaper roll by the rotation of the screw rod, and stop rotating when the two clamping plates move to near the two sides of the sandpaper roll, thereby conveniently fixing the sandpaper roll on the connecting rod.

[0009] Preferably, two limiting rods are fixedly connected to the surface of the fixing plate, and the two limiting rods are slidably connected to the adjustment plate.

[0010] The effect achieved by the above components is that when the adjustment plate is driven to move by the rotation of the first screw, the two limit rods can prevent the adjustment plate from deflecting during the movement.

[0011] Preferably, the upper end of the splint is semicircular, and the inner diameter of the semicircle is adapted to the diameter of the connecting rod.

[0012] The effect achieved by the above components is: because the inner diameter of the semicircular upper end of the splint is adapted to the diameter of the connecting rod, when the upper end of the splint moves to abut against the arc surface of the connecting rod, the connecting rod can prevent the two splints from deflecting during the movement.

[0013] Preferably, the inner wall of the splint is slidably connected to a plurality of balls, and the plurality of balls are evenly distributed on the splint.

[0014] The effect achieved by the above components is that when the upper end of the splint slides on the arc surface of the connecting rod, the plurality of balls can reduce the friction between the splint and the arc surface of the connecting rod, making the splint slide more conveniently.

[0015] Preferably, an auxiliary structure is provided on the side of the cutting machine away from the support frame, and the auxiliary structure includes a slide rail, the slide rail and the cutting machine are fixedly connected, and the inner wall of the slide rail is slidably connected to two sliders, one side of the two sliders is fixedly connected to a limit plate, one side of the limit plate is fixedly connected to a handle, and the sides of the two limit plates away from each other are fixedly connected to a connecting plate, and the inner wall of the connecting plate is threadedly connected to a second screw.

[0016] The effect achieved by the above components is: when the cutting machine finishes cutting the sandpaper and slides out from the front for collection, the limit plate is driven to move by pulling the handle, and the limit plate moves by sliding on the inner wall of the slide rail with the help of the slider. The two limit plates are moved to a position slightly larger than the width of the sandpaper and then stop moving. Finally, the second screw on the inner wall of the connecting plate is rotated to squeeze the surface of the slide rail for fixing. This can prevent the cut sandpaper from deviating from both sides when sliding into the collection box.

[0017] Preferably, one end of the second screw is fixedly connected to an anti-slip pad, and the anti-slip pad is a rubber pad.

[0018] The effect achieved by the above components is that when the second screw is rotated to squeeze the slide rail for fixation, the anti-slip pad can increase the friction between the second screw and the slide rail, thereby making the extrusion and fixation of the second screw more stable.

[0019] Preferably, the inner walls of the two sliding blocks are slidably connected to the same auxiliary rod, and the auxiliary rod is fixedly connected to the slide rail.

[0020] The effect achieved by the above components is that when the slider slides on the inner wall of the slide rail, the auxiliary rod can prevent the slider from deviating when sliding on the inner wall of the slide rail.

[0021] Compared with the related art, the sandpaper processing fixed-distance cutting device provided by the utility model has the following beneficial effects:

[0022] The utility model provides a fixed-distance cutting device for sandpaper processing. When it is necessary to cut sandpaper, the sandpaper roll is put on the arc surface of the connecting rod, and the connecting rod is then installed on the support frame. Then, the rotation of the first motor output end drives the rotation of the first screw, and the rotation of the first screw drives the movement of the adjusting plate, the second motor, the screw rod, the connecting plate and the clamping plate. The adjusting plate slides on the arc surfaces of two limit rods. The two limit rods can prevent the adjusting plate from deflecting during the movement. When the upper end of the clamping plate moves to abut against the arc surface of the connecting rod, it stops rotating. Then, the rotation of the screw rod is driven to rotate the screw rod by the rotation of the second motor output end. Because the arc surface of the screw rod is provided with two reverse threads, the two clamping plates can move away from or close to each other. The two clamping plates are driven to move toward the position of the sandpaper roll by the rotation of the screw rod. When the two clamping plates move to the vicinity of the two sides of the sandpaper roll, they stop rotating. By providing the adjustment structure, when it is necessary to cut sandpaper, the effect of conveniently limiting and fixing sandpaper rolls of different widths can be achieved.

[0023] When the cutting machine finishes cutting the sandpaper and slides out from the front for collection, the limit plate is driven to move by pulling the handle. The limit plate moves with the help of the slider sliding on the inner wall of the slide rail, and the slider slides on the arc surface of the auxiliary rod. The auxiliary rod can prevent the slider from deviating when sliding on the inner wall of the slide rail. The two limit plates are moved to a position slightly larger than the width of the sandpaper and stopped. Finally, the second screw on the inner wall of the connecting plate is rotated to squeeze the surface of the slide rail for fixation. An anti-slip pad is fixed to one end of the second screw. The anti-slip pad can increase the friction between the second screw and the slide rail, making it more stable. By setting the auxiliary structure, the effect of preventing the cut sandpaper from deviating from both sides when sliding into the collection box is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] See also Figures 1 to 5 The embodiment of the present invention provides a fixed-distance cutting device for sandpaper processing, comprising: a cutting machine 1 and an auxiliary structure 4, an operating table 2 is installed on one side of the cutting machine 1, a support frame 5 is provided on the side of the cutting machine 1 away from the auxiliary structure 4, a connecting rod 6 is installed on the upper end of the support frame 5, a sandpaper roll 7 is installed on the arc surface of the connecting rod 6, an adjusting structure 3 is provided on one side of the support frame 5, and an auxiliary structure 4 is provided on the side of the cutting machine 1 away from the support frame 5.

[0033] In the embodiments of the present invention, please refer to Figure 2 and Figure 3The adjusting structure 3 includes a fixing plate 301, which is fixedly connected to the supporting frame 5. The surface of the fixing plate 301 is fixedly connected to the first motor 302. The output end of the first motor 302 is fixedly connected to the first screw 303. The arc surface of the first screw 303 is threadedly connected to the adjusting plate 304. The surface of the adjusting plate 304 is fixedly connected to the second motor 305. The output end of the second motor 305 is fixedly connected to the screw rod 306. The arc surface of the screw rod 306 has two reverse threads. The arc surface of the screw rod 306 is rotatably connected to two connecting plates 307. The two connecting plates 307 are fixedly connected to the adjusting plate 304. The arc surface of the screw rod 306 is fixedly connected to the adjusting plate 304. The arc surface thread is connected to two clamping plates 308. When the sandpaper needs to be cut, the sandpaper roll 7 is put on the arc surface of the connecting rod 6, and then the connecting rod 6 is installed on the support frame 5. Then, the rotation of the output end of the first motor 302 drives the rotation of the first screw 303, and the rotation of the first screw 303 drives the movement of the adjustment plate 304, the second motor 305, the screw rod 306, the connecting plate 307 and the clamping plate 308. When the upper end of the clamping plate 308 moves to abut the arc surface of the connecting rod 6, it stops rotating. Then, the rotation of the output end of the second motor 305 drives the screw rod 306 to rotate. Because the arc surface of the screw rod 306 is opened, the rotation of the screw rod 306 is rotated. The two clamping plates 308 are provided with two reverse threads, so that the two clamping plates 308 can move away from or towards each other, and the two clamping plates 308 are driven to move toward the position of the sandpaper roll 7 by the rotation of the screw rod 306. When the two clamping plates 308 move to the vicinity of the two sides of the sandpaper roll 7, they stop rotating, thereby conveniently limiting and fixing the sandpaper roll 7 on the connecting rod 6. The surface of the fixed plate 301 is fixedly connected to two limiting rods 309, and the two limiting rods 309 are slidably connected to the adjustment plate 304. When the adjustment plate 304 is driven to move by the rotation of the first screw rod 303, the two limiting rods 309 can prevent the adjustment plate 304 from deflecting during the movement, and the clamping plates 308 are fixed to the connecting rod 6. The upper end is semicircular, and the inner diameter of the semicircle is adapted to the diameter of the connecting rod 6. Because the inner diameter of the semicircle at the upper end of the splint 308 is adapted to the diameter of the connecting rod 6, when the upper end of the splint 308 moves to abut against the arc surface of the connecting rod 6, the connecting rod 6 can prevent the two splints 308 from deflecting during the movement. The inner wall of the splint 308 is slidably connected with a plurality of balls 310, and the plurality of balls 310 are evenly distributed on the splint 308. When the upper end of the splint 308 slides on the arc surface of the connecting rod 6, the plurality of balls 310 can reduce the friction between the splint 308 and the arc surface of the connecting rod 6, making the splint 308 slide more conveniently.

[0034] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The auxiliary structure 4 includes a slide rail 41, which is fixedly connected to the cutting machine 1. The inner wall of the slide rail 41 is slidably connected to two sliders 42. One side of the two sliders 42 is fixedly connected to a limit plate 43. One side of the limit plate 43 is fixedly connected to a handle 44. The two limit plates 43 are fixedly connected to a connecting plate 45 on the side away from each other. The inner wall of the connecting plate 45 is threadedly connected with a second screw 46. When the cutting machine 1 finishes cutting the sandpaper and slides out from the front for collection, the limit plate 43 is driven to move by pulling the handle 44. The limit plate 43 moves by sliding on the inner wall of the slide rail 41 with the help of the slider 42. The two limit plates 43 are moved to a position slightly larger than the width of the sandpaper and stop moving. Finally, the limit plate 43 is rotated The second screw 46 on the inner wall of the movable connecting plate 45 squeezes the surface of the slide rail 41 for fixation, thereby preventing the cut sandpaper from deviating from both sides when sliding into the collection box. One end of the second screw 46 is fixedly connected to an anti-skid pad 47, which is a rubber pad. When the second screw 46 is rotated to squeeze the slide rail 41 for fixation, the anti-skid pad 47 can increase the friction between the second screw 46 and the slide rail 41, so that the second screw 46 is squeezed and fixed more stably. The inner walls of the two sliders 42 are slidably connected to the same auxiliary rod 48. The auxiliary rod 48 is fixedly connected to the slide rail 41. When the slider 42 slides on the inner wall of the slide rail 41, the auxiliary rod 48 can prevent the slider 42 from deviating when sliding on the inner wall of the slide rail 41;

[0035] The working principle of the fixed-distance cutting device for sandpaper processing provided by the present invention is as follows: when it is necessary to cut the sandpaper, the sandpaper roll 7 is put on the arc surface of the connecting rod 6, and then the connecting rod 6 is installed on the support frame 5, and then the rotation of the output end of the first motor 302 drives the rotation of the first screw 303, and the rotation of the first screw 303 drives the movement of the adjustment plate 304, the second motor 305, the screw rod 306, the connecting plate 307 and the clamping plate 308. The adjustment plate 304 slides on the arc surface of the two limit rods 309, and the two limit rods 309 can prevent the adjustment plate 304 from deflecting during the movement. When the upper end of the splint 308 moves to abut the arc surface of the connecting rod 6, it stops rotating, and then the rotation of the output end of the second motor 305 drives the screw rod 306 to rotate. Because the arc surface of the screw rod 306 has two reverse threads, the two splints 308 move away from or close to each other, and the rotation of the screw rod 306 drives the two splints 308 to move toward the position of the sandpaper roll 7. When the two splints 308 move to the vicinity of the two sides of the sandpaper roll 7, they stop rotating. By setting the adjustment structure 3, when it is necessary to cut the sandpaper, the sandpaper rolls 7 of different widths can be conveniently limited and fixed.

[0036] When the cutting machine 1 has finished cutting the sandpaper and slides out from the front for collection, the limit plate 43 is driven to move by pulling the handle 44. The limit plate 43 moves by sliding on the inner wall of the slide rail 41 with the help of the slider 42. At the same time, the slider 42 slides on the arc surface of the auxiliary rod 48. The auxiliary rod 48 can prevent the slider 42 from deviating when sliding on the inner wall of the slide rail 41. The two limit plates 43 are moved to a position slightly larger than the width of the sandpaper and stop moving. Finally, the second screw 46 on the inner wall of the connecting plate 45 is rotated to squeeze the surface of the slide rail 41 for fixation. One end of the second screw 46 is fixed with an anti-skid pad 47. The anti-skid pad 47 can increase the friction between the second screw 46 and the slide rail 41, making it more stable. By setting the auxiliary structure 4, the effect of preventing the cut sandpaper from deviating from both sides when sliding into the collection box is achieved.
