Description

Technical Field

[0001] This utility model relates to the field of paper cutting technology for packaging boxes, specifically a paper web bevel cutting fixture. Background Technology

[0002] A paper cutting device for packaging boxes is a specialized device for cutting paper into different sizes. It assists in cutting the paper and then splicing it together to complete the outer packaging process. It is usually equipped with precision cutting blades and drive mechanisms to achieve precise cutting of paper, ensuring cutting accuracy and efficiency. While improving production efficiency and product quality, it also reduces production costs and resource waste.

[0003] In the current paper cutting process, right-angle cuts are often made, which are made vertically. When splicing after cutting, the right-angle cuts will create a step at the joint, making the entire outer packaging uneven, the connection unstable, and prone to breakage, causing the packaged items to leak out. Utility Model Content

[0004] The purpose of this utility model is to provide a paper web bevel cutting fixture. By moving the inclined cutter laterally along the cutter guide, the paper of the packaging box can be cut, so that the cut surface of the paper of the packaging box is inclined, increasing the contact area and assisting the subsequent pressing and connection. This makes the interface of the two inclined surfaces flat during subsequent pressing and connection, avoiding the problem that vertical cutting causes easy breakage after splicing due to reduced contact area. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper web bevel cutting fixture, including a cutter, a cutting base provided at the lower end of the cutter, a recessed and inclined cutting groove provided inside the cutting base facing the cutter, the inclination angle of the cutting groove being the same as the inclination angle of the cutter, a limiting baffle provided laterally at the upper end of the cutter, a sliding block provided on one side of the limiting baffle, a handle provided on the outer wall of the sliding block, the lower end of the limiting baffle being welded and fixed to the upper end of the cutter, the inclined cutter can move laterally at the cutting groove position, and can cut the material at an inclination during the lateral movement, avoiding right-angle cut edges that would reduce the contact area during subsequent connection.

[0006] Preferably, a cutter guide rail is provided on one side of the outer side of the sliding block. The cutter guide rail is slidably embedded inside the sliding block. The cutter guide rail can provide stability for the lateral movement of the cutter, which helps to improve the stability of the cutter movement.

[0007] Preferably, the lower end of the cutting base is provided with a support base, which is fixedly connected to the cutting base and the cutting tool guide rail by bolts. The support base can support the upper cutting base and the cutting tool guide rail, and the support can improve the stability of the tool movement.

[0008] Preferably, a cylindrical pressing strip is provided on one side of the upper end of the support base. By pressing the paper of the package box being cut by the pressing strip, the stability of the paper of the package box when it is cut can be improved, and the paper of the package box can be easily transferred in the future.

[0009] Preferably, both ends of the pressing strip are rotatably provided with transmission blocks, and a threaded rod is vertically inserted through the inside of the transmission block. The outside of the threaded rod is threadedly engaged with the through position of the transmission block. The threaded rod facilitates transmission and allows for easy adjustment of the longitudinal horizontal position of the pressing strip.

[0010] Preferably, a protective cover is provided at the upper end of the two threaded rods, which rotates laterally and covers the upper end of the clamping strip. The protective cover can wrap around the clamping strip at the upper end of the outside of the clamping strip, which can improve the stability during use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a pre-reserved cutting groove for a tilted cutter to move laterally. The tilted cutter, moving laterally along the cutting guide, cuts the packaging paper, resulting in a tilted cut surface. This tilted surface increases the contact area during subsequent splicing, aiding in pressing and connecting the two tilted surfaces. This ensures a smooth interface during pressing and connecting, preventing breakage due to reduced contact area caused by vertical cutting. The tilted cutting position facilitates subsequent splicing, and aside from the change in cutting angle, there's no need to adjust the cutting pattern or the paper transport process, avoiding unnecessary complexities in the entire cutting process.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figure 1 As shown, a paper web bevel cutting fixture of this embodiment includes a cutter 12. The cutter 12 can make contact with the paper of the packaging box by moving laterally, thereby completing the cutting. It can assist in the subsequent processing and production of packaging. A cutting base 6 is provided at the lower end of the cutter 12. The paper of the packaging box to be cut is supported by the cutting base 6 after being transported. The support of the cutting base 6 can improve the stability of cutting and prevent the paper of the packaging box to be cut from being suspended in the air.

[0020] Furthermore, in order to increase the contact area between the interfaces of the packaging box paper, such as... Figure 3 and Figure 4 As shown, the cutting base 6 has a recessed and inclined cutting groove 7 facing the tool 12. The tool 12 can be embedded in the cutting groove 7 to cut the packaging paper. The inclination angle of the cutting groove 7 is the same as that of the tool 12, which is 45°. The same inclination angle can improve the stability of cutting.

[0021] In this embodiment, a limiting baffle 3 is provided laterally at the upper end of the cutter 12, and the lower end of the limiting baffle 3 is welded and fixed to the upper end of the cutter 12. The limiting baffle 3 can drive the lower end of the cutter 12 to move laterally, which can drive the cutter 12 to cut the packaging box paper. At the same time, the limiting baffle 3 can press and restrict both sides of the packaging box paper at the cutting position, improve the neatness of the cut position, and facilitate the subsequent packaging connection and flattening.

[0022] To improve the stability of the lateral movement of the limiting baffle 3, a sliding block 2 is provided on one side of the limiting baffle 3, and a handle 4 is provided on the outer wall of the sliding block 2. The protruding handle 4 makes it easy for the user to hold and the sliding block 2 drives the limiting baffle 3 and the cutter 12 to move laterally in a stable manner, so as to efficiently cut at the required cutting position.

[0023] In this embodiment, a cutter guide rail 1 is provided on one side of the outer side of the sliding block 2. The cutter guide rail 1 is slidably embedded inside the sliding block 2. During the process of holding the handle 4 and moving laterally, the sliding block 2 can slide laterally along the outer side of the cutter guide rail 1. The stability of the movement of the cutter 12 can be improved by restricting the movement of the cutter 12 through the cutter guide rail 1.

[0024] In addition, a support base 13 is provided at the lower end of the cutting base 6. The support base 13 is fixedly connected to the cutting base 6 and the cutter guide rail 1 by bolts. A cylindrical pressing strip 9 is provided on one side of the upper end of the support base 13. During the process of conveying the packaging box paper, the paper is pressed by the rotatable pressing strip 9. The pressing of the pressing strip 9 can improve the stability of the cutting of the packaging box paper and the smoothness of the subsequent conveying of the packaging box paper.

[0025] To accommodate packaging paper of different thicknesses, such as Figure 2 As shown, transmission blocks 10 are provided at both the front and rear ends of the pressing strip 9, and the transmission blocks 10 are rotatably connected to the pressing strip 9. A threaded rod 11 is vertically inserted through the inside of the transmission block 10, and the outside of the threaded rod 11 is threadedly engaged with the through position of the transmission block 10. After the threaded rod 11 rotates, it can vertically drive the pressing strip 9 to move, and the distance between the pressing strip 9 and the support base 13 can be directly adjusted, which can adapt to packaging paper of different thicknesses.

[0026] It is worth mentioning that a protective cover 8 is horizontally provided at the upper end of the two threaded rods 11, and the protective cover 8 covers the upper end of the pressing strip 9. The threaded rods 11 rotate inside the protective cover 8. When the pressing strip 9 presses the packaging paper conveyed at the lower end, the protective cover 8 directly wraps and protects the rotatable pressing strip 9 at the lower end.

[0027] To press and connect the cut paper, a welding platform 5 is provided on the other side of the cutting base 6. After being transported, the packaging paper moves to the upper end of the welding platform 5. The welding platform 5 heats the connecting material, and after the material melts, it is pressed and bonded together by the pressure device at the upper end of the welding platform 5. The heating connecting material and the pressure device are not shown in the accompanying drawings of this utility model. The heating connecting material and the pressure device have not been improved in this utility model. The heating connecting material and the pressure device are conventional operations and materials during splicing, so they are not described in detail in this utility model.

[0028] Working principle: When using the device to cut the packaged paper, the paper is first pressed onto the upper end of the support base 13 by the clamping strip 9. As the paper is continuously pulled to contact the cutter 12 to complete the cut, the clamping strip 9 continues to press the paper against the surface of the support base 13. The rotating threaded rod 11 moves longitudinally relative to the transmission block 10. The distance between the clamping strip 9 and the support base 13 is adjusted to adapt to paper of different thicknesses. After the paper moves laterally a certain distance, the handle 4 is held, and the sliding block 2 is pulled laterally through the handle 4. The sliding block 2 drives the front cutter 12 to slide along the outside of the cutter guide rail 1, while the cutter 12 also slides laterally inside the cutting groove 7. During the sliding process, the cutter 12 tilts to cut the paper. During the cutting process, the two sides of the cutting position are pressed and restricted by the limiting baffle 3. The pressing of the limiting baffle 3 can improve the stability of the cutting and facilitate efficient tilting cutting. The connection can be completed by contacting the two tilting cutting positions. The contact area is large. After being flattened by the connection, the interface is flat and not easy to break.
