Description

Technical Field

[0001] This utility model relates to the field of shearing machines, and more specifically, to a rapid positioning device for grinding tools in shearing machines. Background Technology

[0002] Shearing machines are core equipment in textile finishing, mainly used for trimming the surface of plush, knitted and other fabrics. They achieve smoothing of the plush or shaping of patterns through the coordinated cutting of spiral circular blades and flat blades, and include types such as single-blade shearing machines and combined brushing, heat-pressing and shearing machines.

[0003] In existing technology, textile fabrics need to be trimmed after being raised to make them flat and beautiful. This is done by using a shearing machine to trim the surface of the textile fabric. The service life and accuracy of the shearing roller on the shearing machine largely depend on its grinding process. When grinding the surface of the shearing roller, a positioning module is used to fix the shearing roller. However, the positioning module is generally fixed and not easy to replace. When different types of cutters need to be positioned, the fixed positioning module is not easy to adjust quickly, which reduces the grinding efficiency.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this invention is to provide a quick positioning device for grinding tools of a shearing machine to solve the problems mentioned in the background art.

The lifting plate has a through hole on its side, and a positioning bearing is installed in the through hole. A fixing rod is installed in the positioning bearing, and a positioning plate is installed on the end face of the fixing rod. The surface of the positioning plate has an arc groove, a limiting groove, and a square groove. A clamping plate is fixedly connected to the outer ring surface of the positioning plate by positioning bolts.

[0007] Furthermore, the electric push rod is fixedly connected to the surface of the mounting plate, and the auxiliary plate is fixedly connected to the lifting end of the electric push rod.

[0016] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-6 According to an embodiment of the present invention, a quick positioning device for grinding tools of a shearing machine includes a worktable 1, a processing plate 2 on the surface of the worktable 1, a grinding device 3 on the side of the worktable 1, a mounting plate 4 on the side of the processing plate 2, an electric push rod 5 on the surface of the mounting plate 4, an auxiliary plate 6 on the lifting end of the electric push rod 5, an installation opening 7 on the side of the auxiliary plate 6, a lifting plate 8 inserted into the installation opening 7, a base plate 24 on the side of the lifting plate 8, and a drive motor 10 on the surface of the base plate 24. The grinding device 3 is a common device for grinding shearing rollers installed on a shearing machine. The electric push rod 5 facilitates the height adjustment of the positioning plate 11 for subsequent grinding of the shearing roller surface. The rotation of the drive motor 10 facilitates the adjustment of the angle of the positioning plate 11 for quick use.

[0017] The lifting plate 8 has a through hole on its side, and a positioning bearing 9 is installed in the through hole. A fixing rod 25 is installed in the positioning bearing 9. A positioning plate 11 is installed on the end face of the fixing rod 25. An arc groove 12, a limiting groove 13 and a square groove 14 are opened on the surface of the positioning plate 11. A clamping plate 16 is fixedly connected to the outer ring surface of the positioning plate 11 by a positioning bolt 15. The arc groove 12, the limiting groove 13 and the square groove 14 are designed to facilitate the positioning of different types of shearing rollers. The positioning bearing 9 facilitates the rotation of the fixing rod 25.

[0018] Please see Figures 2-4As shown, the electric push rod 5 is fixedly connected to the surface of the mounting plate 4, and the auxiliary plate 6 is fixedly connected to the lifting end of the electric push rod 5. A baffle 17 is provided on the side of the lifting plate 8, and a support rod 18 is provided on the end face of the lifting plate 8. A damping bearing 19 is sleeved on the surface of the support rod 18, and a limit block 20 is fixedly connected to the outer ring of the damping bearing 19. A groove is provided at the bottom of the limit block 20, and a counterweight 21 is provided inside the groove. The height of the lifting plate 8 can be easily adjusted by the electric push rod 5, thereby facilitating the height adjustment of the positioned shearing roller for grinding. When the electric push rod 5 is not in use, the auxiliary plate 6 is used to adjust the height of the lifting plate 8. The auxiliary plate 6 is placed on the end face of the mounting plate 4. The mounting plate 4 supports the auxiliary plate 6, which helps to reduce the pressure of multiple structures on the lifting end of the electric push rod 5. When it is necessary to remove the lifting plate 8, the limiting block 20 is rotated in conjunction with the damping bearing 19, so that the limiting block 20 is parallel to the mounting port 7, which makes it easy for the limiting block 20 to be disengaged from the mounting port 7, and the lifting plate 8 can be easily removed. The lifting plate 8 is fixed to the lifting end of the electric push rod 5 by bolts. The setting of the counterweight block 21 and the damping bearing 19 in the limiting block 20 prevents the limiting block 20 from rotating arbitrarily.

[0019] Please see Figure 1 , Figure 5 and Figure 6 As shown, the drive motor 10 is fixedly connected to the surface of the base plate 24, and the drive end of the drive motor 10 is fixedly connected to the end face of the fixed rod 25. The fixed rod 25 is fixedly connected to the inner ring surface of the positioning bearing 9. The clamping plate 16 above the limiting groove 13 has a threaded hole on its surface, and a limiting bolt 22 is screwed into the threaded hole. A limiting plate 23 is provided on the side of the clamping plate 16. The limiting groove 13 has a "V" shaped plate structure. The limiting groove 13, together with the limiting bolt 22, facilitates the positioning of irregular structures. The limiting plate 23 facilitates the abutment of the end face of the shearing roller to prevent slippage. The clamping plate 16 can be pushed by rotating the positioning bolt 15. The arc-shaped groove 12 facilitates the positioning of rod-shaped structures, and the square groove 14 facilitates the positioning of square structures.

[0020] Through the above-described solution of this utility model, the arc-shaped groove 12 opened on the surface of the positioning plate 11 facilitates the placement of one end of the shearing roller in the arc-shaped groove 12, and then the clamping plate 16 facilitates the fixing of the shearing roller, which is convenient for subsequent grinding of the surface of the shearing roller by the grinding equipment 3. When it is necessary to position different types of shearing rollers, the positioning groove 13 and the square groove 14 opened on the surface of the positioning plate 11 can be used to increase the positioning of different types of shearing rollers. Then, by starting the electric push rod 5, the height of the shearing roller can be adjusted to facilitate the grinding of the surface of the shearing roller.
