Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0034] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are all conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0035] Example 1

[0036] like Figure 1 The diagram shows the overall structure. This cutting tool structure mainly consists of a displacement part 1 and a cutting part 2. The cutting operation is achieved through the cooperation of a synchronization device 3 and a drive device 4. It is also equipped with a guide and limit structure to enable the cutting tool to flexibly switch scenes and ensure stable operation of the equipment.

[0037] like Figure 2 As shown, the displacement base 11 of the displacement unit 1 has connecting holes for fixed installation with other equipment. Two rows of parallel grooves 112 are provided on both sides of the displacement base 11 for engaging and fixing the support column 121, ensuring stable installation of the support column. A grooved guide block 113 is provided on the side of the displacement base 11, matching the guide rod 212 on the cutting base 21, providing guidance for the movement of the cutting base. A limit block 114 is also provided on the side of the displacement base 11 to limit the travel distance, preventing the cutting base from moving beyond a preset range and avoiding equipment damage or safety accidents.

[0038] The top of the support column 121 is provided with a slide rail mounting groove 1211, in which a displacement slide rail 123 is installed and movably connected to a front-to-back displacement slider 211 fixed below the cutting base 21, allowing the cutting base to move smoothly along the displacement slide rail. A lead screw 122 is provided in the middle of the support column 121, one end of which is fixed to a lead screw frame 111 at the head end of the displacement base 11, and the other end is connected to a servo motor 124 fixed to the tail end of the displacement base 11. A nut seat 125 is installed on the lead screw 122, which is connected to the cutting base 21. When the servo motor 124 drives the lead screw 122 to rotate, the nut seat 125 will drive the cutting base 21 to move back and forth along the lead screw axis, thus forming a front-to-back moving device 12.

[0039] Two rows of left and right horizontal sliding blocks 131 are installed below the displacement base 11. The left and right horizontal sliding blocks cooperate with the horizontal sliding screw on the equipment to be installed. When the horizontal sliding screw is rotated under the drive of the corresponding drive device, the left and right horizontal sliding blocks 131 will move along the axial direction of the horizontal sliding screw, thereby driving the displacement base 11 and the cutting part 2 above it to move in the left and right direction, thus forming the left and right moving device 13.

[0040] Example 2

[0041] like Figure 3 , Figure 4 As shown, this embodiment is a supplement to embodiment 1. A front-to-back displacement slider 211 is fixed below the cutting base 21 of the cutting section 2, which cooperates with the displacement slide rail 123. A set of cutter shaft holders 22 is provided at the front end of the cutting base 21 for movably connecting the cutter shaft 24.

[0042] The cutter shaft holder 22 consists of a free end assembly 221 and a drive end connecting block 222. The drive end connecting block 222 is connected to a cutter shaft protective cover 224 via a hinge 223. The other end of the cutter shaft protective cover 224 is fixed to the free end assembly 221 by bolts and washers, which can protect the cutter shaft and the blade, and at the same time facilitate opening for tool replacement and maintenance. The free end assembly 221 consists of a free end connecting block 2211 and a vertically connected cutter shaft seat 2212. The cutter shaft seat 2212 is connected to the cutting base 21 by bolts, and the bolt slots of the cutter shaft seat 2212 have grooves for adjusting the cutter shaft spacing, so that the position of the cutter shaft can be adjusted according to actual cutting needs.

[0043] The cutter shaft 24 is a rod-shaped structure, movably connected to the cutter shaft holder 22, and at least three sets of blades 23 are mounted on it. The drive end of the cutter shaft is connected to the drive end connecting block, and the free end of the cutter shaft is connected to the free end connecting block. The drive end of the cutter shaft is connected through the synchronization device 3 and driven to rotate by the drive device 4, thereby driving the blades 23 to perform cutting operations.

[0044] Example 3

[0045] like Figure 5 As shown, this embodiment is a supplement to embodiment 2. The synchronization device 3 includes a timing belt 31 and a timing pulley 32 connected to the drive end of the cutter shaft. Through the transmission of the timing belt and the timing pulley, the power of the drive device 4 is smoothly and accurately transmitted to the cutter shaft. The drive device 4 includes a drive motor 41 and a steering gear 42 for connecting the timing pulley. It provides power for the rotation of the cutter shaft and changes the direction of power transmission through the steering gear 42 to adapt to the structural layout of the equipment. Its working process is as follows: after the drive motor 41 starts, it drives the timing pulley 32 to rotate. The timing belt 31 drives the timing pulley 32 connected to the drive end of the cutter shaft, thereby driving the cutting blade to rotate. The servo motor 124 drives the lead screw 122 to rotate, causing the blade to move forward to cut the paper tube. After cutting, the servo motor drives the lead screw 122 to rotate in the opposite direction, the cutter retracts, moves laterally to a designated position, and then repeats the above actions.

[0046] A timing belt cover 5 is installed on the timing pulley, the cutter shaft drive end, and the outside of the timing belt. The timing belt cover 5 is fixed to the cutting base 21 by a right-angle connector, which protects the timing pulley, timing belt and other transmission components, prevents dust and debris from entering and affecting the transmission effect, and avoids personnel from contacting the rotating parts and causing injury.

[0047] This utility model, through the cooperation of a front-to-back moving device and a left-to-right moving device, enables the cutting unit to move flexibly in the front-to-back and left-to-right directions, and precisely adjust the cutting position. A motor-driven synchronous wheel drives the cutter shaft to rotate, realizing the cutting action. The bolt slot of the cutter shaft seat can adjust the position of the cutter shaft, allowing the equipment to be adjusted according to actual needs, thus improving the ease of use of the equipment. In addition, the cutter shaft with the blade can be taken out and replaced by removing the cutter shaft protective cover. Because the cutter shaft is short, one person can easily remove the cutter shaft, realizing flexible disassembly and assembly of the cutter.

[0048] This utility model does not improve any software programs or methods. This utility model only designs the structure. The methods or software programs involved in the debugging and control of the control device and sensors are all based on existing methods or software program design books, manuals or product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this utility model, and can be implemented by writing their own programs.

[0049] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
