[0028] Embodiment
[0029] The present invention provides a sandpaper processing and cutting device with high cutting accuracy. Refer to Figure 1-6 As shown, it includes a workbench 1 and an adjusting mechanism 2, a cutting mechanism 3, and a material pushing mechanism 4 arranged on the workbench 1. The present invention can limit and press the sandpaper during cutting, and at the same time can cut sandpapers of different lengths, thereby improving the cutting accuracy of the sandpaper and the flatness of the cut surface of the sandpaper.
[0030] Refer to Figure 1 The adjusting mechanism 2 shown. The adjusting mechanism 2 includes a fixing plate 201 welded to one end of the workbench 1. The inner side of the fixing plate 201 is provided with a driving plate 204 slidably connected to the workbench 1. The driving plate 204 is parallel to the fixing plate 201. The outer end face of the fixing plate 201 is provided with a fastening threaded column, and a driving threaded hole penetrating the fixing plate is opened on the fastening threaded column. A driving threaded column 202 is screwed in the driving threaded hole, and a fastener 5 is screwed on the driving threaded column 202.
[0031] Further, a number of equally spaced scale lines 102 are symmetrically arranged on both sides of the top end face of the workbench 1. Pointer 205 that cooperates with the scale lines 102 is provided on the bottom end faces of both sides of the driving plate 204. Through the setting of the pointer 205 and the scale lines 102, precise adjustment of the driving plate 204 can be achieved, ensuring the precision of cutting sandpapers of different lengths.
[0032] Further, one end of the driving threaded column 202 extends to the inside of the fixing plate 201 and is rotatably connected to the driving plate 204. The other end of the driving threaded column 202 extends to the outside of the fixing plate 201 and is provided with a rotating handle 203. Through the setting of the rotating handle 203, it is convenient for the staff to rotate the driving threaded column 202 to drive the driving plate 204 to displace.
[0033] Further, guide rods 305 are slidably connected to the bearing plates 302 on both sides of the lifting cylinder 303. The bottom of the guide rods 305 extends to the bottom of the bearing plates 302 and is fixedly connected to the connecting plate 306. The top of the guide rods 305 extends to the outside of the bearing plates 302 and is provided with stop blocks. Through the setting of the guide rods 305, the stability of the lifting cylinder 303 driving the cutting knife 304 and the pressing plate 307 to move up and down is improved, and at the same time, the stability of the cutting knife 304 during cutting is improved.
[0034] Further, a plurality of uniformly distributed trapezoidal guide blocks 206 are provided on the bottom end face of the driving plate 204. Guide grooves 103 adapted to the guide blocks 206 are provided on the workbench 1. Through the setting of the guide blocks 206 and the guide grooves 103, the stability of the forward and backward displacement of the driving plate 204 is improved.
[0035] Among them, referring to Figure 3 the fastener 5 shown, the fastener 5 includes a fastening threaded end 502 screwed to the fastening threaded column and a driving threaded end 501 screwed to the driving threaded column 202. The driving threaded end 501 communicates with the fastening threaded end 502, and internal threads are provided in both the driving threaded end 501 and the fastening threaded end 502. Through the setting of the fastener 5, displacement of the position of the driving plate 204 after long-term use can be avoided, resulting in a decrease in the cutting precision of the sandpaper and affecting the production quality of the sandpaper.
[0036] As Figure 5The cutting mechanism 3 shown, the cutting mechanism 3 includes support plates 301 arranged on both sides of the workbench 1. A bearing plate 302 is welded between the tops of the two support plates 301. An elevating cylinder 303 is provided on the top end face of the bearing plate 302. The output end of the elevating cylinder 303 extends to the bottom of the bearing plate 302 and is provided with a connecting plate 306 parallel to the bearing plate 302. A cutting knife 304 is provided on the bottom end face of the connecting plate 306. A cutter groove 101 is penetrated and opened on the workbench 1 directly below the cutting knife 304. Pressing plates 307 in the shape of long rectangles are symmetrically arranged on both sides of the cutting knife 304. A plurality of sliding rods slidably connected to the connecting plate 306 are provided on the top end face of the pressing plate 307. Through the arrangement of the sliding rods, the stability of the up and down displacement of the pressing plate 307 is improved, and at the same time, the stability of pressing the sandpaper is improved.
[0037] Furthermore, a driving spring 308 is sleeved outside the sliding rod between the pressing plate 307 and the connecting plate 306. One end of the driving spring 308 is fixedly connected to the top end face of the pressing plate 307, and the other end of the driving spring 308 is fixedly connected to the bottom end face of the connecting plate 306. Through the arrangement of the driving spring 308, it can be ensured that the pressing plate 307 always presses and fixes the sandpaper during cutting. At the same time, the elastic force generated by the extrusion of the driving spring 308 further improves the pressing effect of the pressing plate 307.
[0038] Furthermore, the bottom end face of the pressing plate 307 is lower than the bottom end face of the cutting knife 304, so that it can be ensured that the pressing plate 307 contacts the sandpaper stack to be cut one step ahead of the cutting knife 304, enabling the pressing plate 307 to press and fix the sandpaper stack to be cut before cutting, thus greatly improving the accuracy of sandpaper cutting and the flatness of the sandpaper cut surface.
[0039] As Figure 6 shown by the feeding mechanism 4, the feeding mechanism 4 is arranged between the adjusting mechanism 2 and the cutting mechanism 3, and includes a mounting frame 401 in an inverted L-shaped structure arranged on one side of the workbench 1. A feeding cylinder 402 is provided on the top end face of the mounting frame 401. A push rod 403 is provided on the output end of the feeding cylinder 402. A push plate 404 for pushing the cut sandpaper out of the workbench 1 is provided at the end of the push rod 403 away from the feeding cylinder 402. The bottom end face of the push plate 404 is attached to the top end face of the workbench 1, so as to facilitate pushing the sandpaper out of the workbench 1.
[0040] The working principle of the present utility model is:
[0041] In use, first adjust according to the length of the sandpaper to be cut through the adjusting mechanism 2. The staff drives the driving threaded column 202 by rotating the handle 203 to drive the driving plate 204 to move back and forth. When the driving plate 204 moves, through the setting of the pointer 205 cooperating with the scale line 102, the adjustment accuracy of the adjusting mechanism 2 can be ensured. After the driving plate 204 is adjusted, tighten the fastener 5 on the driving threaded column 202 so that the fastening threaded end 502 on the fastener 5 is screwed and fixed with the fastening threaded column, thereby avoiding the displacement of the driving plate 204 caused by long-term use and the decrease in the cutting accuracy of the sandpaper. Then, place the stack of sandpaper to be cut stacked up and down on the workbench 1 so that one end of the sandpaper stack is in contact with the inner end face of the driving plate 204. Next, start the lifting cylinder 303 to drive the cutting knife 304 and the pressing plate 307 to move downward in the vertical direction to cut the sandpaper stack. The pressing plate 307 contacts the sandpaper stack to be cut one step ahead of the cutting knife 304, so that the pressing plate 307 can press and fix the sandpaper stack to be cut before cutting, thereby greatly improving the accuracy of sandpaper cutting and the flatness of the sandpaper cut surface. After the sandpaper is cut, the lifting cylinder 303 drives the cutting knife 304 and the pressing plate 307 to move upward, and start the pushing cylinder 402 to drive the push rod 403 and the push plate 404 to move, so as to push the cut sandpaper stack out of the workbench 1, facilitating subsequent cutting work and greatly improving the applicability of the present utility model.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0043] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
