[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a knife head detachable shearing machine, including a frame 1, a knife head body 2 and a movable groove 5. The knife head body 2 is movably installed inside the frame 1. The movable grooves 5 are symmetrically distributed at the left and right ends of the frame 1, and a knife head limit structure is provided inside the movable groove 5;

[0020] The knife head limit structure includes a support seat 6 and a limit post 7. The limit post 7 is rotatably connected inside the support seat 6. Pulley 8 and limit protrusion 9 are respectively arranged at the left and right ends of the limit post 7, and the limit protrusion 9 is in a fitting connection with the knife head body 2.

[0021] The pulley 8 and the limit projection 9 form a lever structure with respect to the connection end position of the support base 6. The pulley 8 drives the limit projection 9 to rotate around the support base 6 through transmission. The limit projection 9 enhances the resistance to the cutter head body 2 through the lever force, can stably clamp and fix one end of the cutter head body 2, and the stress points are evenly distributed. The limit projection 9 is not easily deformed during fixation.

[0022] A screw rod 10 is threadedly connected inside the movable groove 5. One end of the screw rod 10 is movably connected to a slider 11. The screw rod 10 drives the slider 11 to horizontally displace inside the movable groove 5 through the way of threaded transmission with the movable groove 5. During the operation, the operator only needs to control the screw rod 10, and the screw rod 10 is far from the cutter head limit end, avoiding potential safety hazards during the replacement operation.

[0023] The slider 11 is in sliding fit with the movable groove 5. The outer surface of one end of the slider 11 is of an inclined structure. The slider 11 adjusts the angle of the slider 11 by using its own shape structure. In the normal state, the lower end of the inclined surface of the slider 11 is in contact with the pulley 8. During the horizontal movement of the slider 11, the pulley 8 will slide from the lower end of the inclined surface of the slider 11 to the higher end, so as to realize the clamping and fixing of the cutter head body 2.

[0024] The slider 11 is movably connected to the pulley 8. The diameter of the pulley 8 is larger than the outer diameter of the limit post 7. During the sliding process of the slider 11 and the pulley 8, only the surface of the pulley 8 is in contact, avoiding the outer edge of the limit post 7 from blocking the moving routes of the pulley 8 and the slider 11.

[0025] Positioning grooves 4 are symmetrically distributed inside the frame 1. Positioning posts 3 are movably connected inside the positioning grooves 4. The positioning posts 3 are symmetrically distributed on the outer surface of one end of the cutter head body 2. Before installing the cutter head body 2, the positioning posts 3 need to be aligned with the positioning grooves 4 of the frame 1 to ensure the correct installation position of the cutter head body 2.

[0026] Working principle: First, the cutter head body 2 is pre-fixed and supported on a platform that can be lifted. The positioning posts 3 of the cutter head body 2 are aligned with the positioning grooves 4 of the frame 1. The positioning posts 3 and the positioning grooves 4 are docked by vertical lifting. Subsequently, the screw rod 10 is controlled to rotate and is in threaded transmission with the movable groove 5, so that one end of the screw rod 10 pushes the limit post 7 to horizontally slide inside the movable groove 5. During the sliding process, the inclined surface of the movable groove 5 pushes the pulley 8, so that the limit post 7 rotates around the support base 6 as the center point, so that the limit projection 9 at one end of the limit post 7 fits and clamps the surface of the cutter head body 2, so as to limit and fix the whole cutter head body 2. The structure is simple and practical, and during the operation, the staff does not need to contact the cutter body, which can avoid potential safety hazards during the disassembly and assembly process.

[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
