Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-5 , a cloth cutting mechanism, including a cloth cutting machine body 1, a lifting plate 2 is arranged above the cloth cutting machine body 1, and a cutting knife 3 is installed below the lifting plate 2. The cutting principle of the lifting plate 2 and the cutting knife 3 is the prior art and will not be elaborated here. A connecting frame 4 is connected to the side of the lifting plate 2, and a connecting shaft 5 is inserted inside the connecting frame 4. A connecting bar 6 is sleeved outside the connecting shaft 5, and a threaded rod 7 is inserted inside the connecting bar 6. A grinding block 8 is arranged at the bottom end of the threaded rod 7. The bottom end opening position of the connecting bar 6 is connected by a bearing with a threaded sleeve 9, and the threaded rod 7 is inserted into the threaded sleeve 9. The top end of the threaded rod 7 is connected with a guide bar 10. A moving groove adapted to the guide bar 10 is opened inside the connecting bar 6. Through the mutual cooperation of the guide bar 10 and the moving groove, the limiting of the threaded rod 7 can be realized, so that the threaded rod 7 can stably move inside the connecting bar 6. Through the threaded cooperation of the threaded sleeve 9 and the threaded rod 7, the height of the grinding block 8 can be adjusted, so that the grinding block 8 can be lifted during cutting to meet the normal cutting requirements of the cutting knife 3. When grinding is required, the grinding block 8 can be lowered so that the inner wall of the grinding block 8 abuts against the outer wall of the cutting knife 3.

[0024] Furthermore, referring to Figure 4 it can be known that a motor 11 is installed on the inner wall of the connecting frame 4, and the output end of the motor 11 is connected to one end of the connecting shaft 5. The other end of the connecting shaft 5 is connected to the inner wall of the connecting frame 4 through a bearing. By driving the motor 11, the rotation of the connecting shaft 5 can be driven. External threads are provided on the outer surface of the connecting shaft 5, and a threaded groove adapted to the connecting shaft 5 is opened at the top end of the connecting bar 6. Therefore, when the motor 11 works, the reciprocating grinding of the grinding block 8 can be automatically driven without manual movement of the grinding block 8 by the staff.

[0025] Furthermore, referring to Figure 4It can be known that mounting plates 13 are symmetrically connected to the upper side of the connecting frame 4, and the inside of the mounting plates 13 is connected to the lifting plate 2 by bolts. Through the setting of the mounting plates 13, it is convenient for the staff to disassemble the connecting frame 4 from the side of the lifting plate 2.

[0026] Furthermore, referring to Figure 3 and Figure 4 It can be known that a connecting rod is connected to the outer side of the threaded sleeve 9, and the connecting rods are distributed in an annular array structure on the outer surface of the threaded sleeve 9. Through the mutual cooperation of multiple groups of connecting rods, it is convenient for the staff to rotate the threaded sleeve 9, thereby effectively improving the convenience of using this device.

[0027] Furthermore, referring to Figure 4 and Figure 5 It can be known that a clamping plate 14 is connected to the bottom end of the threaded rod 7, and the clamping plate 14 is set in an L-shaped structure. The clamping plate 14 is sleeved above the connecting plate 15, and the side of the connecting plate 15 is connected to the grinding block 8. A limiting rod 16 is inserted into the inside of the clamping plate 14, and a pulling block 17 is connected to the end of the limiting rod 16. An embedding groove adapted to the limiting rod 16 is opened on the side of the connecting plate 15. Through the L-shaped clamping plate 14 and the cooperation of the limiting rod 16 and the pulling block 17, the worn grinding block 8 can be replaced.

[0028] Furthermore, referring to Figure 5 It can be known that a spring 18 is horizontally connected to the inner side of the pulling block 17, and the other end of the spring 18 is connected to the clamping plate 14. Through the connection of the spring 18, the tightness of the limiting rod 16 embedded in the connecting plate 15 can be ensured.

[0029] Furthermore, referring to Figure 4 It can be known that a slider 12 is connected to the inner side of the connecting bar 6, and a chute adapted to the slider 12 is opened on the inner wall of the connecting frame 4. Through the mutual cooperation of the slider 12 and the chute, the guiding of the connecting bar 6 can be realized to ensure that the connecting bar 6 slides stably inside the connecting frame 4.

[0030] Working principle: When the utility model is in use, the staff can first place the fabric on the fabric cutting machine body 1, and then drive the up and down movement of the cutting knife 3 through the lifting plate 2 to achieve the cutting of the fabric. When the cutting knife 3 becomes blunt after cutting for a period of time, the staff can first rotate the threaded sleeve 9, so that it is in threaded cooperation with the threaded rod 7, so that the threaded rod 7 moves inside the connecting bar 6, and then the whole grinding block 8 can be driven to move downward. Then the staff can start the motor 11, so that it drives the rotation of the connecting shaft 5. At this time, the connecting shaft 5 is in threaded cooperation with the connecting bar 6, so that the grinding block 8 slides on the outside of the cutting knife 3 to achieve the grinding operation of the cutting knife 3. After the grinding is completed, the staff can rotate the threaded sleeve 9 in the reverse direction to make the threaded rod 7 retract into the connecting bar 6, so as to drive the whole grinding block 8 to lift, so as not to affect the normal up and down cutting of the cutting knife 3. The above is the whole working principle of the utility model.
