It's typically made by gluing various abrasive grains onto a base paper. Depending on the abrasive material, there are various types of sandpaper, including emery paper, artificial emery paper, and glass sandpaper. Because the shearing device rounds the unflattened sandpaper, it bends, making it difficult to stack and store.

A fixed plate, and both sides of the bottom of the fixed plate are fixedly connected to the first extrusion plate through a first hydraulic rod, the top of the bottom plate is fixedly connected to the second motor through a fixed seat, and the output shaft of the second motor is fixedly connected to the driving gear, and the surface of the driving gear is connected to the transmission gear through a conveyor belt transmission, the top of the bottom plate and the right side of the second motor are fixedly connected with the stacking groove and the cutting groove from left to right, the bottom of the top plate and above the stacking groove and the cutting groove are respectively fixedly connected with the second hydraulic rod and the third hydraulic rod through a support plate, and the bottom ends of the second hydraulic rod and the third hydraulic rod are fixedly connected to the second extrusion plate.

[0004] However, research has shown that the existing sandpaper stacking and flattening still has the following defects:

However, directly using the pressing plate to act on the sandpaper may cause excessive pressure, thereby damaging the sandpaper. At the same time, the pressure of the pressing plate is difficult to adjust, making it difficult to flatten sandpaper with different degrees of curvature. Therefore, it is necessary to optimize a sandpaper stacking and flattening device with a buffer mechanism through technological innovation and design optimization. Utility Model Content

[0006] When flattening the stacked sandpaper, the existing stacking flattening machine generally uses a pressing plate to flatten it directly. However, directly using the pressing plate to act on the sandpaper may cause excessive pressure, thereby damaging the sandpaper. At the same time, the pressure of the pressing plate is difficult to adjust, making it difficult to flatten sandpaper with different degrees of curvature. In order to solve the above problems, the embodiment of the present application provides a sandpaper stacking flattening device with a buffer mechanism, which buffers the pressing plate through the buffer mechanism, and then buffers the sandpaper, thereby preventing the force of the hydraulic press from directly acting on the sandpaper and causing damage to the sandpaper. At the same time, by rotating the circular ring, the length of the guide column between the circular plate and the pressing plate can be adjusted, and then the elastic force of the spring can be adjusted, thereby completing the adjustment of the sandpaper pressure and improving applicability.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A sandpaper stacking and flattening device with a buffer mechanism, comprising:

[0009] The bottom plate has a supporting leg fixed at the bottom, an arc-shaped plate 2 is provided on one side of the top of the bottom plate, and an arc-shaped plate 1 is provided on the other side of the top of the bottom plate. The bottom plate is provided with a moving mechanism that can drive the arc-shaped plate 1 to move. An L-shaped plate is fixed on the top of the bottom plate, and a hydraulic press is installed on the top of the L-shaped plate. The output end of the hydraulic press passes through the L-shaped plate and is connected to a circular plate. A pressure plate is provided at the bottom of the circular plate, and a buffer mechanism that can buffer the pressure plate is provided between the circular plate and the pressure plate.

[0010] In one possible implementation, the buffer mechanism includes guide columns fixed on both sides of the top of the pressure plate, the top of the guide column passes through the circular plate, and the outside of the guide column is provided with a spring located between the circular plate and the pressure plate area. The guide column can slide on the circular plate, and the hydraulic press drives the circular plate and the pressure plate to move downward. When the pressure plate contacts the sandpaper, the pressure plate will drive the guide column to slide on the circular plate and squeeze the spring at the same time to prevent the force of the hydraulic press from directly acting on the sandpaper and causing damage to the sandpaper.

[0011] In one possible implementation, a thread is provided on the top of the guide column, and a ring is threadedly connected to the top of the circular plate on the outside of the guide column. The ring can be rotated to adjust the length of the guide column between the circular plate and the pressure plate, and then adjust the elastic force of the spring, thereby completing the adjustment of the sandpaper pressure.

[0012] In a possible implementation, fixing columns are fixed on both sides of the bottom of the ring 1, and anti-slip grooves are provided on the outer side of the ring 1, so that the ring 1 does not adhere tightly to the top of the circular plate, making it easy to rotate the ring 1.

[0013] In one possible implementation, annular grooves are provided on both sides of the top of the circular plate, a second circular ring is provided inside the annular groove, and a cylindrical groove is provided on the top of the second circular ring to facilitate the insertion of the fixing column into the cylindrical groove and drive the second circular ring to rotate.

[0015] In a possible implementation, the second circular ring can slide in the annular groove, and the fixing column can be inserted into the cylindrical groove, so that the fixing column can drive the second circular ring to rotate in the annular groove.

[0016] In a possible implementation, the circular plate and the pressure plate are of the same size and shape, and the circular plate and the pressure plate can move up and down between the first arc plate and the second arc plate, so that the circular plate can move the pressure plate to flatten the sandpaper.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. When the pressure plate contacts the sandpaper, the pressure plate will drive the guide column to slide on the circular plate. At this time, the guide column will drive the ring 1 and the fixed column to move upward, and at the same time squeeze the spring to prevent the force of the hydraulic press from directly acting on the sandpaper and causing damage to the sandpaper. At the same time, the ring 1 is rotated, and the ring 1 drives the ring 2 to rotate through the fixed column. At this time, the ring 1 will adjust the length of the guide column between the circular plate and the pressure plate, and then adjust the elastic force of the spring, thereby completing the adjustment of the sandpaper pressure. It can be adjusted according to the bending degree of the sandpaper, which improves applicability.

[0019] 2. The motor drives the screw to rotate, the screw drives the rectangular block to move, and the rectangular block drives the arc plate 1 to move, so that the arc plate 1 cooperates with the arc plate 2 to align the stacked sandpaper, which is convenient for the subsequent flattening work. There is no need for staff to align, which improves the alignment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] This embodiment introduces the specific structure of a sandpaper stacking and flattening device with a buffer mechanism. Figure 1-Figure 4 As shown, a sandpaper stacking and flattening device with a buffer mechanism includes:

[0027] The bottom plate 3 has a supporting leg 1 fixed at the bottom of the bottom plate 3, an arc-shaped plate 2 8 is provided on one side of the top of the bottom plate 3, and an arc-shaped plate 1 9 is provided on the other side of the top of the bottom plate 3. The bottom plate 3 is provided with a moving mechanism that can drive the arc-shaped plate 1 9 to move. An L-shaped plate 4 is fixed on the top of the bottom plate 3, and a hydraulic press 5 is installed on the top of the L-shaped plate 4. The output end of the hydraulic press 5 passes through the L-shaped plate 4 and is connected to a circular plate 6. A pressure plate 7 is provided at the bottom of the circular plate 6, and a buffer mechanism that can buffer the pressure plate 7 is provided between the circular plate 6 and the pressure plate 7.

[0028] When stacking and flattening machines on the market flatten the stacked sandpaper, they generally use the pressing plate 7 to flatten the stacked sandpaper. However, directly using the pressing plate 7 to act on the sandpaper may cause excessive pressure, thereby causing damage to the sandpaper.

[0029] The buffer mechanism includes guide columns 17 fixed on both sides of the top of the pressure plate 7. The top of the guide column 17 passes through the circular plate 6. The outside of the guide column 17 is located between the circular plate 6 and the pressure plate 7 and is sleeved with a spring 14. The guide column 17 can slide on the circular plate 6. The hydraulic press 5 drives the circular plate 6 and the pressure plate 7 to move downward. When the pressure plate 7 contacts the sandpaper, the pressure plate 7 will drive the guide column 17 to slide on the circular plate 6 and squeeze the spring 14 at the same time to prevent the force of the hydraulic press 5 from directly acting on the sandpaper and causing damage to the sandpaper.

[0030] The buffer mechanism can adjust the pressure of the pressing plate 7 for sandpaper with different bending degrees, so as to adapt to different sandpaper.

[0031] In addition, a thread is provided on the top of the guide column 17, and the outside of the guide column 17 is located on the top of the circular plate 6 and is threadedly connected to a ring 13. The ring 13 can be rotated, and the ring 13 will adjust the length of the guide column 17 between the circular plate 6 and the pressure plate 7, and then adjust the elastic force of the spring 14, thereby completing the adjustment of the sandpaper pressure.

[0032] Furthermore, fixing columns 15 are fixed on both sides of the bottom of the ring 13, and anti-slip grooves are provided on the outside of the ring 13, so that the ring 13 is not tightly attached to the top of the circular plate 6, making it easy to rotate the ring 13.

[0033] At the same time, annular grooves are provided on both sides of the top of the circular plate 6, and a second circular ring 16 is provided inside the annular groove. A cylindrical groove 18 is provided on the top of the second circular ring 16 to facilitate the insertion of the fixing column 15 into the cylindrical groove 18 and drive the second circular ring 16 to rotate.

[0034] The sandpaper needs to be stacked before flattening and then arranged neatly to facilitate subsequent flattening work.

[0035] In one possible implementation, the moving mechanism includes a rectangular groove 10 provided on the top of the base plate 3, a rectangular block 12 sliding inside the rectangular groove 10, a screw rod 11 provided inside the rectangular groove 10, one end of the screw rod 11 passes through the rectangular block 12 and is rotatably connected to the inner wall of the rectangular groove 10, a motor 2 is installed on one side of the base plate 3, the output end of the motor 2 passes through the base plate 3 and is fixedly connected to the other end of the screw rod 11, the top of the rectangular block 12 is fixedly connected to the bottom of the arc plate 9, the screw rod 11 is threadedly connected to the rectangular block 12, the motor 2 drives the screw rod 11 to rotate, the screw rod 11 drives the rectangular block 12 to move, and the rectangular block 12 drives the arc plate 9 to move, so that the arc plate 9 cooperates with the arc plate 2 8 to align the stacked sandpaper, so that the subsequent flattening work does not require alignment by staff, which improves the alignment efficiency and also avoids the displacement of the sandpaper during flattening.

[0036] In addition, the second circular ring 16 can slide in the annular groove, and the fixing column 15 can be inserted into the cylindrical groove 18, so that the fixing column 15 can drive the second circular ring 16 to rotate in the annular groove.

[0037] More importantly, the size of the circular plate 6 is the same as that of the pressing plate 7, and the circular plate 6 and the pressing plate 7 can move up and down between the arc plate 1 9 and the arc plate 2 8, so that the circular plate 6 can mobilize the pressing plate 7 to flatten the sandpaper.

[0038] When the staff needs to flatten the sandpaper, the stacked sandpaper is placed close to the arc plate 2 8 on the bottom plate 3, and the motor 2 is turned on. The motor 2 drives the screw rod 11 to rotate, the screw rod 11 drives the rectangular block 12 to move, and the rectangular block 12 drives the arc plate 1 9 to move, so that the arc plate 1 9 cooperates with the arc plate 2 8 to align the stacked sandpaper, so as to carry out the subsequent flattening work without the need for staff to align, thereby improving the alignment efficiency and avoiding the displacement of the sandpaper during flattening. At this time, the hydraulic press 5 is turned on, and the hydraulic press 5 drives the circular plate 6 and the pressure plate 7 to move downward. When the pressure plate When 7 contacts the sandpaper, the pressure plate 7 will drive the guide column 17 to slide on the circular plate 6. At this time, the guide column 17 will drive the ring 13 and the fixed column 15 to move upward, and at the same time squeeze the spring 14 to prevent the force of the hydraulic press 5 from directly acting on the sandpaper and causing damage to the sandpaper. When the pressure of the pressure plate 7 needs to be changed, the ring 13 is rotated, and the ring 13 drives the ring 2 16 to rotate through the fixed column 15. At this time, the ring 13 will adjust the length of the guide column 17 between the circular plate 6 and the pressure plate 7, and then adjust the elastic force of the spring 14, thereby completing the adjustment of the sandpaper pressure.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
