DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a slitting knife holder that is easy to disassemble and assemble a blade, comprising a knife holder body 1, a slitting blade 5 and a servo motor 7, a movable bracket 2 and a fixed bracket 3 are respectively installed at the left and right ends of the knife holder body 1, a movable mounting seat 4 is connected to the bottom end of the fixed bracket 3, a limiting shaft 6 is respectively installed inside the movable mounting seat 4 and the movable bracket 2 and is connected to the slitting blade 5 through the limiting shaft 6, the limiting shaft 6 connected to the movable bracket 2 is connected to the output end of the servo motor 7, a guide rod 12 is provided at the top of the movable mounting seat 4, a guide groove 14 matching the length of the guide rod 12 is provided inside the fixed bracket 3, a positioning hole 13 for inserting a fixed positioning piece 16 is provided inside the guide rod 12, and the fixed positioning piece 16 is slidably matched with a slide groove 15 provided inside the movable mounting seat 4.

[0019] A stepper motor 8 is installed on the outer surface of one end of the tool holder body 1, and a lead screw 9 is connected to the output end of the stepper motor 8. The stepper motor 8 has a certain precision. By controlling the lead screw 9 and the movable bracket 2 for threaded transmission, the accuracy of the horizontal displacement spacing of the movable bracket 2 can be ensured, which is convenient for positioning the displacement of the movable bracket 2.

[0020] The movable bracket 2 is threadedly connected to the screw rod 9, and the movable bracket 2 and the tool holder body 1 are slidably matched by setting a guide rail 10. The movable bracket 2 is supported and guided by the guide rail 10. The guide rail 10 slides through horizontal displacement and can be adaptively adjusted according to the length of the slitting blade 5, ensuring that the tool holder body 1 can be installed with slitting blades 5 of various lengths.

[0021] The sum of the vertical lengths of the fixed bracket 3 and the movable mounting seat 4 is the same as the vertical length of the movable bracket 2 .

[0022] The movable mounting seat 4 is internally threadedly connected with a control handle 11, which is movably connected to a positioning member 16. The control handle 11 and the movable mounting seat 4 are threadedly driven to move horizontally, and one end of the control handle 11 can push the positioning member 16 to move synchronously, ensuring that the positioning member 16 switches its position inside the slide groove 15.

[0023] The guide rod 12 and the guide groove 14 are movably plugged in. The guide rod 12 forms a limiting installation structure with the positioning member 16 through the positioning hole 13. The outward protrusion on the outer surface of one end of the positioning member 16 is adapted to the size of the positioning hole 13. During the horizontal movement, the positioning member 16 is plugged into the positioning hole 13 of the guide rod 12 through the front end protrusion, so as to fix the current position of the movable mounting seat 4, thereby supporting the slitting blade 5. The modular structure facilitates the disassembly and assembly of the slitting blade 5. The slitting blade 5 can be pre-fixed before disassembly and assembly, and effective support is provided. Only manual assistance is required, which increases the overall disassembly and assembly efficiency.

[0024] Working principle: When using the slitting knife holder which is easy to disassemble and assemble the blade, ensure that the distance between the movable bracket 2 and the fixed bracket 3 is greater than the length of the slitting blade 5, one end of the slitting blade 5 is inserted into the limiting shaft 6 of the movable mounting seat 4, and then the guide rod 12 of the movable mounting seat 4 is vertically corresponding to and inserted into the guide groove 14 of the fixed bracket 3, and the rotating control handle 11 pushes one end of the positioning member 16 to be inserted into the positioning hole 13 of the guide rod 12 to support one end of the slitting blade 5, and then start the stepping motor 8 to control the screw rod 9 and the movable bracket 2 to transmit the thread, so that the movable bracket 2 moves horizontally along the guide rail 10, and the other end of the slitting blade 5 is inserted into the limiting shaft 6 of the movable bracket 2 through the horizontal position to complete the installation, and repeat the above steps when disassembly and assembly are required, and start the servo motor 7 to rotate the slitting blade 5 to start the slitting work, thereby increasing the overall practicality.
