Description

Technical Field

[0001] This utility model relates to the field of sandpaper processing technology, specifically a sandpaper winding device. Background Technology

[0002] Sandpaper, also known as abrasive paper, is a material used for grinding. It's used to polish surfaces such as metal and wood to make them smooth and glossy. It's typically made by attaching various abrasive particles to a base paper. Depending on the abrasive material, there are various types, including diamond sandpaper, synthetic diamond sandpaper, and glass sandpaper. Dry sandpaper (wood sandpaper) is used to polish the surfaces of wood and bamboo. Water-resistant sandpaper (wet sandpaper) is used to polish the surfaces of metal or non-metal workpieces in water or oil. The base paper is made entirely from unbleached sulfate wood pulp, making it strong, durable, and resistant to tearing and folding, with good water resistance. Abrasive materials such as glass abrasive are bonded to the base paper with adhesives such as resin, and then the paper is dried.

[0003] After sandpaper is processed, a winding device is needed to wind it up. However, when using the winding device, different sizes of winding rollers cannot be changed according to the width of the sandpaper. Different models of winding devices need to be used to wind up the sandpaper, which greatly increases the production cost of sandpaper. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a winding device for sandpaper processing, which has the advantages of being able to change the winding roller of different sizes according to the width of the sandpaper, thus solving the problem that the winding roller of different sizes cannot be changed according to the width of the sandpaper.

[0005] This utility model discloses a sandpaper winding device, comprising a support plate, a winding assembly on the top right side of the support plate, a fixing plate at the bottom of the fixing plate and a motor at the top right side of the fixing plate, the output end of the motor extending through and to the left side of the fixing plate, a rotating rod at the output end of the motor, four equally spaced locking holes on both sides of the inner cavity of the rotating rod, baffles on both sides of the rotating rod surface, and a limiting plate fixedly connected to the inner side of the baffles. Six limiting blocks are fixedly connected at equal intervals, and the inner cavity of the limiting plate is movably connected to the rotating rod. A sliding sleeve is fixedly connected to the outer side of the limiting plate, and the inner cavity of the sliding sleeve is movably connected to the rotating rod. A fixing bolt is fitted inside the sliding sleeve, and the surface of the fixing bolt penetrates the sliding sleeve and the locking hole and extends to the bottom of the sliding sleeve. A fixing nut is threaded to the bottom of the surface of the fixing bolt. A take-up roller is fitted on one side of each of the two limiting plates. Six limiting grooves that are adapted to the limiting blocks are equally spaced on both sides of the inner cavity of the take-up roller. This utility model is based on... After selecting a take-up roller that matches the sandpaper width, first remove the left-side baffle, limiting plate, and sliding sleeve from the rotating rod. Then, place the take-up roller onto the rotating rod. Next, place the left-side baffle, limiting plate, and sliding sleeve back onto the rotating rod. Move the two sliding sleeves inward, causing the baffle to move inward, which in turn causes the limiting plate to move inward. When the limiting plate is positioned within the inner cavity of the take-up roller, the limiting block on the limiting plate engages with the limiting groove to secure the take-up roller. At this point, the fixing bolts are inserted into the locking holes on the sliding sleeve and the rotating rod. Then, secure the roller by... The nut secures the fixing bolt. After the fixing bolt is secured, the sliding sleeve can be fixed to the rotating rod by the fixing bolt and the locking hole. The sliding sleeve can limit the position of the baffle and the limiting plate. The winding roller can be fixed on the limiting plate by the limiting block and the limiting groove. At this time, the winding roller can fix the sandpaper. In this way, when winding sandpaper of different widths, only the winding roller of the corresponding size needs to be replaced, without the need to replace different models of winding devices to wind the sandpaper, thus greatly reducing the production cost of sandpaper.

[0006] This utility model discloses a sandpaper winding device, wherein an assembly assembly is provided on the left side of the top of the bearing plate. The assembly assembly includes a connecting plate, which is located on the left side of the top of the bearing plate. A movable shaft is fixedly connected to the top right side of the connecting plate, and the inner cavity of the movable shaft is rotatably connected to a rotating rod. After the winding assembly has fixed the winding roller of the required size, the movable shaft on the connecting plate is sleeved on the surface of the rotating rod. This makes the rotating rod more stable when rotating, avoiding the situation where the rotating rod has limited load-bearing capacity when there is no movable shaft, which would lead to poor performance of the rotating rod.

[0007] The present invention relates to a sandpaper winding device, wherein both ends of the connecting plate are fixedly connected to mounting plates, and the inner cavity of the mounting plate is fixedly connected to the bearing plate through mounting rods. The mounting plates and mounting rods can fix the connecting plate, thus improving the performance of the connecting plate during use and preventing the connecting plate from shaking during use, which would lead to instability of the components on the connecting plate.

[0008] The present invention relates to a sandpaper winding device, wherein anti-slip pads are fixedly connected to both sides of the bottom of the bearing plate, and the bottom of the anti-slip pads are provided with anti-slip threads. The anti-slip pads can fix the bearing plate, thus improving the bearing plate's performance during use and preventing the bearing plate from shaking and causing instability in the components on the bearing plate.

[0009] The present invention relates to a sandpaper winding device, wherein the left side of the movable shaft is fixedly connected to the connecting plate by welding, and the left side of the movable shaft is located at the center of the top right side of the connecting plate.

[0010] The present invention relates to a sandpaper winding device, wherein the center points of the baffle, the limiting plate, and the sliding sleeve are aligned, and the inner cavities of the baffle, the limiting plate, and the sliding sleeve are all in close contact with the rotating rod.

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

[0012] 1. In this utility model, after selecting a matching take-up roller according to the sandpaper width, first remove the left-side baffle, limiting plate, and sliding sleeve from the rotating rod. Then, place the take-up roller onto the rotating rod. At this point, place the left-side baffle, limiting plate, and sliding sleeve onto the rotating rod again. Then, move the two sliding sleeves inward, which in turn moves the baffle inward, and the baffle inward, which in turn moves the limiting plate inward. When the surface of the limiting plate is fitted into the inner cavity of the take-up roller, the take-up roller is fixed by the cooperation of the limiting block on the limiting plate and the limiting groove. At this time, the fixing bolts are inserted into the locking holes on the sliding sleeve and the rotating rod. Then, the fixing bolts are fixed with fixing nuts. After the fixing bolts are fixed, the sliding sleeve can be fixed to the rotating rod by the fixing bolts and the locking holes. The sliding sleeve can limit the baffle and the limiting plate. The winding roller can be fixed on the limiting plate by the limiting block and the limiting groove. At this time, the winding roller can fix the sandpaper. In this way, when dealing with sandpaper of different widths, only the winding roller of the corresponding size needs to be replaced for winding. There is no need to replace different models of winding devices to wind the sandpaper, which greatly reduces the production cost of sandpaper.

[0013] 2. In this utility model, after the winding assembly has fixed the winding roller of the required size, the movable shaft on the connecting plate is sleeved on the surface of the rotating rod. This makes the rotating rod more stable when rotating, avoiding the situation where the rotating rod has limited load-bearing capacity when there is no movable shaft, which would lead to poor performance of the rotating rod.

[0014] The mounting plate and mounting rod can be used to fix the connecting plate, which makes the connecting plate more effective during use and prevents it from shaking, thus avoiding instability of the components on the connecting plate.

[0015] The anti-slip pads can fix the support plate in place, which makes the support plate more effective during use and prevents it from shaking, thus avoiding instability of the components on the support plate. Attached Figure Description

The cavity is movably connected to the rotating rod 205. A sliding sleeve 2010 is fixedly connected to the outer side of the limiting plate 207, and the inner cavity of the sliding sleeve 2010 is movably connected to the rotating rod 205. A fixing bolt 209 is fitted inside the inner cavity of the sliding sleeve 2010, and the surface of the fixing bolt 209 penetrates the sliding sleeve 2010 and the locking hole 208 and extends to the bottom of the sliding sleeve 2010. A fixing nut 2011 is threaded to the bottom of the surface of the fixing bolt 209. A take-up roller 203 is fitted on one side of the two limiting plates 207 respectively. Six limiting grooves 2012 that are adapted to the limiting block 206 are equally spaced on both sides of the inner cavity of the take-up roller 203. After selecting the matching take-up roller 203 according to the width of the sandpaper, the left side baffle is first... 204. The limiting plate 207 and the sliding sleeve 2010 are removed from the rotating rod 205. Then, the take-up roller 203 is fitted onto the rotating rod 205. At this time, the left baffle 204, the limiting plate 207, and the sliding sleeve 2010 are fitted onto the rotating rod 205. Then, the two sliding sleeves 2010 move inward, driving the baffle 204 to move inward, which in turn drives the limiting plate 207 to move inward. When the surface of the limiting plate 207 is fitted into the inner cavity of the take-up roller 203, the limiting block 206 on the limiting plate 207 cooperates with the limiting groove 2012 to fix the take-up roller 203. At this time, the fixing bolt 209 is inserted into the locking hole 208 on the sliding sleeve 2010 and the rotating rod 205. The fixing nut 2011 fixes the fixing bolt 209. After the fixing bolt 209 is fixed, the sliding sleeve 2010 can be fixed on the rotating rod 205 by the cooperation of the fixing bolt 209 and the locking hole 208.

This makes the rotating rod 205 more stable when rotating, avoiding the situation where the rotating rod 205 has limited load-bearing capacity when there is no movable shaft 302, which would lead to poor performance of the rotating rod 205.

[0027] Mounting plates 303 are fixedly connected to both ends of the connecting plate 301, and the inner cavity of the mounting plate 303 is fixedly connected to the bearing plate 1 through the mounting rod 304.

[0030] The center points of the baffle 204, the limiting plate 207 and the sliding sleeve 2010 are consistent, and the inner cavities of the baffle 204, the limiting plate 207 and the sliding sleeve 2010 are all in close contact with the rotating rod 205.

[0031] When using this utility model: After selecting the matching take-up roller 203 according to the sandpaper width, first remove the left side baffle 204, limiting plate 207, and sliding sleeve 2010 from the rotating rod 205. Then, put the take-up roller 203 onto the rotating rod 205. At this time, put the left side baffle 204, limiting plate 207, and sliding sleeve 2010 onto the rotating rod 205. Then, the two sliding sleeves 2010 move inward, driving the baffle 204 to move inward, which in turn drives the limiting plate 207 to move inward. When the surface of the limiting plate 207 is fitted into the inner cavity of the take-up roller 203, the taking-up roller 203 is fixed by the cooperation of the limiting block 206 on the limiting plate 207 and the limiting groove 2012. At this time, the fixing bolt 209 is inserted into the sliding sleeve 2010. The fixing bolt 209 is fixed in the locking hole 208 on the rotating rod 205 and then fixed in the fixing nut 2011.
