Description

Technical Field

[0001] The utility model belongs to the technical field of paper cutting equipment, in particular to a paper cutting equipment with a fast-adjusting cutter structure. Background Art

[0002] Paper cutting equipment is a mechanical device used to cut large sheets of paper into desired sizes and is widely used in the printing, packaging, and papermaking industries. Common paper cutting equipment includes flat blade cutters, circular blade cutters, and laser cutters. These devices utilize different cutting methods to achieve efficient and accurate paper cutting, thereby improving production efficiency and product quality. While existing paper cutting equipment is competent for paper cutting, it still has shortcomings. Some traditional devices lack a mechanism for adjusting the cutting distance, making it difficult to flexibly adjust the cutter blade during the cutting operation. This prevents the paper roll from being cut into sections of varying lengths, significantly reducing the equipment's flexibility. A common solution is to introduce a computer control system that automatically adjusts the cutter blade according to software instructions. This allows for quick adaptation to different cutting requirements by setting preset parameters. However, this approach has the disadvantage of increased operational complexity, which in turn increases the risk of failure and maintenance costs. Furthermore, the operator's required professional skills and familiarity with the new system hinder the equipment's universal applicability. Therefore, a new structure is proposed to address these issues. Utility Model Content

A motor box 320 is provided on the right side of the fixed pipe 310.

[0027] A power mechanism, a control mechanism, and a power supply mechanism are provided inside the control box 110. The output end on the right side of the power mechanism is fixedly connected to the left side of the docking base two 130;

[0028] The docking base two 130 and the rotary connection pipe 131 are of an integral structure. A first thread is provided on the outer side of the rotary connection pipe 131. The radius length and height of the rotary connection pipe 131 match the radius length and depth of the docking groove. An internal thread groove one with a specification matching that of the first thread is opened inside the docking groove.

[0029] The radius length of the positioning rod 200 matches the inner radius length of the sliding sleeve 210. The front side of the sliding sleeve 210 is fixedly connected to the rear side of the connecting rod 230. The rear side of the connecting rod 230 is movably sleeved outside the fixed pipe 310 through a set of sleeves.

[0030] The left side of the fixed tube 310 does not contact the right side of the cutting circular knife 300. The right side of the fixed tube 310 is connected through and communicated with the left side of the motor box 320. A small motor is installed inside the motor box 320. The output end on the left side of the small motor is connected to a group of transmission shafts. The left side of the transmission shaft is connected to the right side of the cutting circular knife 300. A group of grips are installed on the front of the motor box 320.

[0031] Sliding grooves are provided on both the front and back of the positioning rod 200. Sliders are provided on both the front and back inside the sliding sleeve 210. The length, width, and height of the sliders match the length, width, and height of the sliding grooves. The two groups of sliders slide along the two groups of sliding grooves, so that the screw holes 211, the positioning holes 201, and the positioning screw 220 can always be kept on the same vertical line, and then it can be ensured that the positioning screw 220 can smoothly insert downward along the screw hole 211 into the positioning hole 201.

[0032] The positioning hole 201 and the screw hole 211 are on the same vertical line. The radius length of the positioning hole 201 is the same as the radius length of the screw hole 211. The radius length of the screw hole 211 matches the radius length of the positioning screw 220.

[0033] External threads two are provided on the lower outer side of the positioning screw 220. Internal screw grooves two with specifications matching those of the external threads two are provided inside the screw hole 211. The rotational connection between the positioning screw 220 and the screw hole 211 can push the positioning screw 220 to move downward along the screw hole 211 and insert into the positioning hole 201, thus playing a role in fixing the sliding sleeve 210.

[0034] Example 1: Please refer to Figures 1 to 4 , in actual use, the bracket 100 can play a role in stable support, ensuring the overall stability of the equipment. First, apply glue to the outer side of the paper sleeve 121, then pick up the paper roll. A hard paper tube is adhesively bonded to the inner side of the paper roll, and paper is wound on the outer side of the hard paper tube. The inner side of the hard paper tube is sleeved on the outer side of the paper sleeve 121, and the inner side of the hard paper tube is adhesively bonded and fixed to the outer side of the paper sleeve 121. Then pick up the docking base one 120, align the screw groove 122 on the left side of the docking base one 120 with the screw tube 131 on the right side of the docking base two 130, and rotate and connect the screw tube 131 and the screw groove 122 tightly, so as to connect and fix the docking base one 120 and the docking base two 130. Then the paper sleeve 121 is fixed on the right side of the control box 110. At this time, the leftmost side of the sleeve pipe is aligned with the leftmost side of the positioning rod 200. Then the operator holds the grip with the right hand and moves the sliding sleeve 210 with the left hand, so that the two groups of sliders move along the two groups of sliding grooves. The sliding connection between the sliders and the sliding grooves can keep the positioning hole 201 and the screw hole 211 on the same vertical line all the time, so it is convenient for the positioning screw 220 to be screwed in. The distance between adjacent two groups of positioning holes 201 is 2 cm. Therefore, according to the number of the positioning holes 201, the moving distance can be known, and thus the cutting distance length can be known;

[0035] When the sliding sleeve 210 moves above the positioning hole 201 at a corresponding distance, rotate the positioning screw 220 at this time so that the positioning screw 220 is rotationally connected to the screwing hole 211. The positioning screw 220 moves downward along the screwing hole 211, and finely adjust the sliding sleeve 210 left and right so that the bottom of the positioning screw 220 is inserted downward into the corresponding positioning hole 201, thereby completing the positioning of the sliding sleeve 210, and then completing the positioning of the cutting circular knife 300. The final effect is to facilitate the flexible adjustment of the position of the cutting circular knife 300, so that the cutting length of the paper roll can be flexibly adjusted. The overall structure is simple and the operation is quick and convenient.

[0036] Embodiment 2: Please refer to Figure 1 , after the adjustment is completed, start the power mechanism inside the control box 110 and the small motor inside the motor box 320 respectively (the small motor and the power mechanism are both prior arts, and their working principles and internal structures are common knowledge, which will not be elaborated here). The power mechanism drives the docking base two 130 to rotate, thereby driving the docking base one 120 and the paper sleeve 121 to rotate. The paper sleeve 121 is adhesively connected to the hard paper tube, so that the paper roll rotates. The small motor rotates to drive the cutting circular knife 300 to rotate through the transmission shaft. Then hold the handle with the right hand and rotate it downward so that the bottom of the cutting circular knife 300 approaches the top of the paper roll and cuts the paper roll (when cutting, it is not necessary to cut to the bottom, and it is judged whether the paper roll is completely cut according to the paper feeding depth of the cutting circular knife 300). Then lift the handle upward to move the cutting circular knife 300 away from the paper roll. Adjust the sliding sleeve 210 according to the above steps, and perform the second cut after positioning. Repeat this way to perform positioning cutting on the paper roll. After the paper roll is cut, the outermost edge position of the paper can be pulled and then wound in the reverse direction to separate the paper from the outside of the hard paper tube. The paper adhesively connected to the outside of the hard paper tube at the bottom can be discarded. Therefore, the cut paper can be separated from the hard paper tube. The final effect is that the overall structure is simple, the operation is fast and convenient, and it is easy to use.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
