Technical Field

[0001] This utility model relates to the field of cutting machines, and more specifically, to a cutting machine for carton processing with adjustable cutting spacing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products today. When producing cardboard boxes, cardboard cutting machines are usually used to cut the cardboard into various sizes as needed. Cardboard cutting machines are high-end automated CNC equipment that integrates functions such as cutting, drawing, creasing, dotted lines, and drawing. They are widely used in the cardboard box production process.

[0003] Current cutting machines need to cut different sizes of cardboard, requiring adjustable-gap cutting blades. Existing technology uses a screw and threaded seat to move the cutting blade horizontally on a guide rail, achieving precise adjustment of the cutting gap. However, during cutting, the blade is prone to edge warping due to uneven force when cutting thin cardboard, affecting cut quality. Traditional anti-warping structures are mostly fixed and cannot adapt to different blade positions to adjust positioning requirements. How to invent a cardboard cutting machine with adjustable cutting gap to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a carton cutting machine with adjustable cutting spacing. It aims to improve the existing technology, which uses the cooperation of screw and threaded seat to drive the cutting blade to move horizontally on the guide rail to achieve precise adjustment of the cutting spacing. However, when cutting thin cardboard, the cutting blade is prone to edge warping due to uneven force, which affects the cut quality. Traditional anti-warping structures are mostly fixed and cannot adapt to the different positions of the cutting blades to adjust the positioning requirements.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example, refer to Figure 1-4 A carton cutting machine with adjustable cutting spacing includes a worktable 1 and a conveyor roller 5 disposed on the worktable 1. The top of the worktable 1 has an opening 2. The machine also includes: an adjustable cutting mechanism 3 disposed in the opening 2, which can adjust the cutting spacing as needed; and an anti-curling mechanism 4 disposed on the worktable 1, which can position the cardboard to be cut and prevent it from curling up during cutting.

[0022] The adjustable cutting mechanism 3 includes a rotating shaft 301 located inside the opening 2. One end of the rotating shaft 301 is connected to a bearing located on the side wall of the worktable 1. A motor 300 is located on the side wall of the worktable 1. The output end of the motor 300 is connected to one end of the rotating shaft 301. Four sets of connecting sleeves 303 are fitted onto the outer wall of the rotating shaft 301. Two sets of positioning grooves 305 are provided on the side wall of the rotating shaft 301. Two sets of positioning blocks that cooperate with the positioning grooves 305 are provided on the inner wall of the connecting sleeves 303. Under the action of the positioning grooves 305 and the positioning blocks, the connecting sleeves 303 move more stably on the outer wall of the rotating shaft 301. Fixing bolts 304 are provided through the outer walls of the four sets of connecting sleeves 303. Cutting blades 302 are fitted onto the outer walls of the four sets of connecting sleeves 303.

[0023] It should be noted that: loosening the fixing bolt 304 allows the connecting sleeve 303 to slide. The positioning block and positioning groove 305 cooperate to prevent the cutting blade 302 from rotating. After adjustment, tightening the fixing bolt 304 completes the adjustment. There is no need to disassemble the rotating shaft 301.

[0024] The anti-tilting mechanism 4 includes a mounting frame 400 on the side wall of the workbench 1, a sliding rod 401 on the inner wall of the mounting frame 400, five sets of sliding blocks 402 sleeved on the outer wall of the sliding rod 401, a locking bolt 403 penetrating the side wall of the sliding block 402, a first electric telescopic rod 404 at the bottom of the sliding block 402, a positioning frame 411 at one end of the first electric telescopic rod 404, and a positioning roller 405 rotatably connected inside the positioning frame 411.

[0025] It should be noted that the position of the positioning roller 405 can be adjusted by the cooperation of the sliding block 402, the sliding rod 401 and the locking bolt 403, and can cooperate with the cutting blades 302 at different positions. The first electric telescopic rod 404 drives the positioning roller 405 to press down onto the surface of the cardboard, providing vertical pressure.

[0026] The positioning frame 411 has a damped hinged connection to a connecting block 406. One end of the connecting block 406 has a second electric telescopic rod 407. One end of the second electric telescopic rod 407 has a fixing block 408. The side wall of the fixing block 408 is rotatably connected to a rotating rod 409. Both ends of the rotating rod 409 are equipped with positioning wheels 410.

[0027] It should be noted that the second electric telescopic rod 407 pushes the positioning wheel 410 to clamp the edge of the cardboard from both sides, forming a three-point positioning, which completely suppresses the warping.

[0028] Working principle: According to the carton cutting size requirements, adjust the spacing of the cutting blades 302, loosen the fixing bolts 304, slide the connecting sleeve 303 along the rotating shaft 301 to the target position, tighten the fixing bolts 304 to fix the connecting sleeve 303, fix the cutting blades 302, and at the same time loosen the locking bolts 403, move the sliding block 402 to the corresponding position of the cutting blades 302 and lock it. The cardboard is fed into the worktable 1 by the conveying rollers 5 and reaches above the opening 2. The first electric telescopic rod 404 extends, driving the positioning roller 405 to press down on the surface of the cardboard. The second electric telescopic rod 407 extends, pushing the positioning wheel 410 to clamp the edge of the cardboard from both sides. The motor 300 drives the rotating shaft 301 to rotate at high speed, driving the cutting blades 302 to make multiple parallel cuts on the cardboard. After the cutting is completed, the motor 300 stops, the first electric telescopic rod 404 and the second electric telescopic rod 407 retract, the positioning roller 405 and the positioning wheel 410 are separated from the cardboard, and the conveying roller 5 sends the finished product out of the worktable.

[0029] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
