Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and particularly relates to a paper cutting device capable of preventing cutting and shaking. Background Art

[0002] Paper cups usually refer to cups made of paper, which are mainly used to hold beverages or food. Paper cups can be single-layer or multi-layer structures, and generally have a certain degree of water resistance to ensure that they will not be completely penetrated within a certain period of time. Common paper cups are usually used as disposable beverage or food containers. During the production process of paper cups, a cutting device is required to cut the base paper to facilitate the subsequent processing of paper cups.

[0003] In some existing paper cutting devices, before the base paper for paper cup production reaches the cutting roller and the supporting roller, the cutting roller and the supporting roller continuously roll and cut the base paper, causing the base paper to shake violently during rolling and cutting. This causes the base paper to shake or shake during the cutting process, which may cause inaccurate or uneven cutting lines and affect the final cutting effect. Therefore, we hope to design a paper cutting device with a new structure to solve this problem. Utility Model Content

[0025] 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 of 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.

[0026] See also Figures 1 to 4 The utility model provides a technical solution: a paper cutting device for preventing cutting shaking, comprising: a roller cutter body 100 and a stabilizing assembly 200, the stabilizing assembly 200 is installed on the front side of the roller cutter body 100, a mounting frame 110 is installed in the middle of the roller cutter body 100, a conveyor belt 120 is installed on the rear side of the roller cutter body 100, and a stand 130 is installed on the right side of the roller cutter body 100;

[0027] The stabilizing assembly 200 includes a vertical plate 210, a smoothing member 1 220, a smoothing member 230, a guide roller 240 and a tensioning roller 250. The tensioning roller 250 is movably installed on the front upper side between the two symmetrically arranged vertical plates 210, and the guide roller 240 is rotatably installed on the front side between the two vertical plates 210.

[0028] A first smoothing member 220 is installed at the lower rear side between the two vertical plates 210 , and a second smoothing member 230 is installed at the upper rear side between the two vertical plates 210 .

[0029] See also Figures 1 to 3 A support roller 112 is rotatably installed on the lower side of the mounting frame 110, and a die-cutting roller 111 is rotatably installed on the upper side of the mounting frame 110. The support roller 112 is located directly below the die-cutting roller 111. The structure and size of the die-cutting roller 111 can be set according to actual cutting requirements. The die-cutting roller 111 cooperates with the support roller 112 to die-cut the base paper to obtain the arc-shaped paperboard required for making paper cups.

[0030] The specifications of the smoothing member 1 220 are the same as those of the smoothing member 230 , and the installation direction of the smoothing member 1 220 is opposite to that of the smoothing member 230 .

[0031] The second smoothing member 230 includes a mounting plate 234, a movable rod 235, a spring 236 and a fixed plate 233. The fixed plate 233 is movably mounted on the inner side of the mounting plate 234 through the movable rod 235 and the spring 236. A flexible brush 237 is arranged on the side of the fixed plate 233 away from the spring 236.

[0032] The front side of the flexible bristles 237 is arranged in an arc-shaped structure.

[0033] As the first embodiment of the utility model, in actual use, when the base paper passes through the stabilizing component 200, if its tension needs to be adjusted, the user can adjust the tension of the base paper conveying by adjusting the height of the tensioning roller 250. When the base paper moves toward the smoothing member 1 220 and the smoothing member 2 230 through the guide roller 240, the arc structure at the front end of the flexible bristles 237 can facilitate the base paper to pass between the smoothing member 1 220 and the smoothing member 2 230. When the base paper reaches the die-cutting roller 111 for die-cutting, the vibration generated drives the subsequent base paper to vibrate. This part of the vibrating base paper is located between the smoothing member 1 220 and the smoothing member 2 230. The flexible bristles 237 can be deformed under the vibration of the base paper to absorb the vibration energy, thereby reducing the vibration amplitude of the base paper when it reaches the die-cutting roller 111 for die-cutting, which helps to improve the quality of die-cutting.

[0034] See also Figure 3 to Figure 4The upper side of the spring 236 abuts against the inner wall of the mounting plate 234 , the lower side of the spring 236 abuts against the outer wall of the fixing plate 233 , a nut is threadedly connected to the upper side of the movable rod 235 , and the upper side of the movable rod 235 is slidably connected to the mounting plate 234 .

[0035] A connecting plate 232 is installed on the rear side of the fixing plate 233, and a plurality of linearly distributed spring pieces 231 are installed on the rear side of the connecting plate 232 by screws;

[0036] The lower end of the spring piece 231 is arranged horizontally, and the height of the lower end of the spring piece 231 is flush with the lower end of the flexible bristle 237. The smoothing piece 1 220 and the smoothing piece 230 are installed symmetrically about the base paper. The smoothing piece 1 220 and the smoothing piece 230 can cushion the vibration of the base paper that is about to contact the die-cutting roller 111, reduce its shaking amplitude during die-cutting, and improve the quality of the product after die-cutting.

[0037] The spring piece 231 is a stainless steel elastic sheet with a Z-shaped structure. An arc-shaped curved portion is arranged at the front side of the lower end of the spring piece 231 , and the surface of the lower end of the spring piece 231 is designed to be smooth.

[0038] As the second embodiment of the present utility model, based on the above-mentioned first embodiment, the setting of the spring piece 231, a plurality of spring pieces 231 distributed linearly and arranged on the upper and lower sides of the base paper, can limit the base paper for normal die-cutting. At the same time, the spring piece 231 with its own elasticity can produce deformation and buffer vibration when the base paper vibrates, thereby reducing the vibration amplitude of the base paper and reducing the vibration impact on subsequent base paper, ensuring that the subsequent base paper can be die-cut with a lower vibration amplitude during die-cutting, thereby helping to reduce the shaking amplitude during paper cutting and improving the die-cutting quality.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
