All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1: As Figures 1-5 shown, a device for reducing the loss of the fixed distance sleeve of the thick longitudinal shear shaft provided by the present utility model includes a mounting frame 1.

A second support frame 15 is fixedly installed at the top of the mounting frame 1. A positioning frame 16 is fixedly installed inside the mounting frame 1. A lifting assembly 17 is fixedly installed at the top of the positioning frame 16.

[0029] Specifically, the lifting assembly 17 includes a cylinder 1701. A connecting block 1703 is fixedly installed on the output shaft of the cylinder 1701. A first fixing column 1704 is fixedly installed on one side of the connecting block 1703. A swing arm 1705 is fixedly installed on the other side of the first fixing column 1704. A first rotating column 1706 is rotatably installed at the other end of the swing arm 1705. A fixing member 1707 is fixedly installed at the top of the swing arm 1705. A second fixing column 1708 is fixedly installed at the other end of the fixing member 1707. A second rotating column 1709 is rotatably installed on one side of the swing arm 1705. The advantage is that through the design of the lifting assembly 17, an external solenoid valve can be connected, and then the cylinder 1701 can be controlled to expand and contract through the solenoid valve. Subsequently, the cylinder 1701 drives the swing arm 1705 through the connecting block 1703 and the first fixing column 1704, and the up and down swing can be realized.

[0030] Specifically, a supporting roller 1710 is fixedly installed on the outside of the second rotating column 1709. The supporting roller 1710 is a steel roller, and the surface of the supporting roller 1710 is chrome-plated. The advantage is that through the design of the supporting roller 1710, when the waste edge 14 contacts the surface of the supporting roller 1710, it can play a guiding role for the waste edge 14, and with the cooperation of the steel roller and the chrome-plated surface, the wear resistance can be increased and its service life can be improved.

[0031] Specifically, the cylinder 1701 is located at the top of the positioning frame 16, and the connecting block 1703, the first fixing column 1704 and the swing arm 1705 are adapted to each other.

[0032] Embodiment 2: As Figures 2-5 shown, as an improvement over the previous embodiment.

[0033] Specifically, the other ends of the first rotating column 1706 and the second fixing column 1708 are in contact with the second support frame 15, and the swing range of the swing arm 1705 is 15° to 45°. The advantage is that when working, the placement angle of the swing arm 1705 can be 15°, which can reduce the angle between the waste edge 14 or the material body 12 and the horizontal direction of the outlet of the circular shear 11 during shearing, reduce the contact surface between the waste edge 14 or the material body 12 and the polyurethane distance sleeve, solve the problem that the polyurethane distance sleeve is prone to wear, and ensure the quality of material shearing.

[0034] Specifically, the connecting frame 7 is in an "L" - shaped structure, and a plurality of positioning bolts 8 are arranged at two connection positions of the connecting frame 7. The positioning bolts 8 are respectively connected to the mounting frame 1 and the first support frame 9. The advantage is that by the "L" - shaped connecting frame 7 and with the design of the positioning bolts 8, the connecting frame 7 can connect the mounting frame 1 and the first support frame 9 to realize its fixed installation and prevent the first support frame 9 from being prone to displacement.

[0035] Specifically, the material body 12 and the strip 13 are located between two circular shears 11, the strip 13 is located on the top of the idler roller 1710, and the waste edge 14 is located between the first traction roller 5 and the second traction roller 6. The advantage is that through the design of the two circular shears 11, the material body 12 can be cut into the strip 13 and the waste edge 14, so that the strip 13 is in the upper working position, and then the waste edge 14 reaches the threading position, and with the cooperation of the first traction roller 5 and the second traction roller 6, the waste edge 14 can also be guided.

[0036] Working principle: During use, the placement angle of the swing arm 1705 can be set at 15°, which can reduce the angle between the waste edge 14 or the material body 12 and the horizontal direction at the outlet of the circular shear 11 during shearing, reducing the contact area between the waste edge 14 or the material body 12 and the polyurethane distance sleeve, solving the problem that the polyurethane distance sleeve is prone to wear, ensuring the quality of material shearing. Since the cylinder 1701 is located at the top of the positioning frame 16, it can fix the cylinder 1701. And with the cooperation of the connecting block 1703, the first fixing column 1704 and the swing arm 1705, the cylinder 1701 can push the swing arm 1705 to achieve angle transformation. Through the design of the idler roller 1710, when the waste edge 14 contacts the surface of the idler roller 1710, it can guide the waste edge 14. And with the cooperation of the steel roller and chromium plating on the surface, the wear resistance can be increased and its service life can be extended. Through the design of the lifting assembly 17, an external solenoid valve can be connected. Then, the solenoid valve controls the telescopic movement of the cylinder 1701. Subsequently, the cylinder 1701 drives the swing arm 1705 through the connecting block 1703 and the first fixing column 1704 to achieve up and down swinging. Since the connecting frame 7 is in an "L" shape and with the design of the positioning bolt 8, the connecting frame 7 can be connected to the mounting frame 1 and the first support frame 9 to achieve fixed installation, preventing the first support frame 9 from being easily displaced. Through the design of two circular shears 11, the material body 12 can be cut into strips 13 and waste edges 14, with the strip 13 in the upper working position. Then, the waste edge 14 reaches the threading position, and the first traction roller 5 and the second traction roller 6 can also guide the waste edge 14.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
