Description

Technical Field

[0001] This utility model relates to the field of paper packaging processing technology, and in particular to a cutting device for producing paper packaging boxes. Background Technology

[0002] In the production of paper packaging boxes, the precision and efficiency of the cutting process directly determine the product quality and production efficiency. With the rapid development of e-commerce logistics and the fresh food cold chain industry, the market demand for personalized packaging boxes is increasing. However, existing cutting equipment still faces many technical bottlenecks in practical applications.

[0003] Traditional equipment cannot flexibly adjust the pressing position and force when processing cardboard. Improper tension control can easily lead to material displacement and wrinkles. Even if some equipment is equipped with a pressing device, it is mostly a rigid connection. It cannot provide a continuous elastic force like a push spring to ensure that the pressing part is always tightly attached to the paper. During high-speed conveying, cutting size deviations are prone to occur, affecting subsequent forming processes. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a cutting device for producing paper packaging boxes, including a support platform 1, a conveyor belt 2 is provided inside the support platform 1, and pressing components 3 are provided on both sides of the support platform 1.

[0027] The pressing assembly 3 includes a fixed frame 301. The lower end of the fixed frame 301 is fixedly connected to both sides of the support platform 1. A sliding frame 302 is fixedly connected to the surface of the fixed frame 301. A sliding rod 303 is fixedly connected to the inner wall of the sliding frame 302. Two sliding sleeves 304 are slidably connected to the surface of the sliding rod 303. An X-shaped movable frame 305 is rotatably connected to the lower end of the two sliding sleeves 304. Two pressing frames 307 are fixedly connected to the lower end of the X-shaped movable frame 305. A pressing roller 308 is rotatably connected to the inner wall of the two pressing frames 307.

[0028] Specifically, the number of sliding frames 302 is set to two sets, and the two sets of sliding frames 302 are symmetrically arranged on the surface of the fixed frame 301. Push springs 306 are sleeved on both ends of the sliding rod 303. One end of the push spring 306 abuts against one side of the sliding sleeve 304. The top of the fixed frame 301 is fixedly connected to the mounting base 309, and the surface of the mounting base 309 is provided with the cutting component 4.

[0029] Furthermore, the sliding frame 302 on the surface of the fixed frame 301, in conjunction with the sliding rod 303 and the sliding sleeve 304, allows the X-shaped movable frame to be flexibly adjusted in position, thereby driving the lower pressure frame 307 and the lower pressure roller 308 to press the paper. The push springs 306 at both ends of the sliding rod 303 can provide a continuous elastic force to the sliding sleeve 304, ensuring that the lower pressure roller 308 is always in close contact with the paper surface, effectively preventing the paper from shifting or wrinkling during the conveying and cutting process, ensuring the stability of the paper conveying, and laying a reliable foundation for the accurate execution of the subsequent cutting process. At the same time, the two sets of symmetrically arranged sliding frames 302 structures further improve the balance of the downward pressure force and enhance the adaptability of the equipment to different paper specifications.

[0030] Example 2

[0031] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention. Based on the previous embodiment, the cutting component 4 includes a movable arm 401, which is rotatably connected to the surface of the mounting base 309. The other end of the movable arm 401 is rotatably connected to a movable seat 402. An adjustment frame 403 is fixedly connected to one side of the movable seat 402. A bidirectional lead screw 404 is rotatably connected to the inner wall of the adjustment frame 403. A handle 409 is fixedly connected to one end of the bidirectional lead screw 404. Two movable frames 406 are threadedly connected to the surface of the bidirectional lead screw 404. A cutting frame 407 is fixedly connected to one side of the two movable frames 406. A cutting blade 408 is rotatably connected to the surface of the cutting frame 407.

[0032] Specifically, an auxiliary rod 405 is slidably connected to the top of the movable frame 406. The two ends of the auxiliary rod 405 are fixedly connected to the inner wall of the adjustment frame 403. The surface of the adjustment frame 403 is provided with scale lines 410. Fixed knobs are provided at the connection points of the movable arm 401 with the mounting base 309 and the movable base 402.

[0033] Furthermore, through the rotatable connection between the movable arm 401 and the mounting base 309 and the movable base 402, the spatial position of the cutting blade 408 can be flexibly adjusted with the fixed knob to meet the cutting requirements of different angles. The bidirectional lead screw 404 in the adjustment frame 403 cooperates with the moving frame 406 to precisely adjust the distance between the two cutting frames 407. The auxiliary rod 405 ensures the stability of the moving frame 406 during movement, preventing the cutting blade 408 from shaking and affecting the cutting accuracy. The scale line 410 on the surface of the adjustment frame 403 provides a reference for the distance adjustment, making it easy for operators to quickly and accurately set the cutting size, significantly improving the cutting accuracy and efficiency.

[0034] Working principle: The sliding frame 302 on the surface of the fixed frame 301, through the cooperation of the sliding rod 303 and the sliding sleeve 304, allows the X-shaped movable frame to be flexibly adjusted in position, thereby driving the lower pressure frame 307 and the lower pressure roller 308 to come close to the paper surface. The push springs 306 at both ends of the sliding rod 303 provide a continuous elastic force to the sliding sleeve 304, ensuring that the lower pressure roller 308 is always in close contact with the paper, effectively preventing the paper from shifting or wrinkling during the conveying process, ensuring smooth conveying, and laying the foundation for the subsequent cutting process. In addition, the two sets of symmetrically arranged sliding frames 302 further improve the balance of the downward pressure force and enhance the adaptability to different paper sizes. When the paper is conveyed to the cutting position, the movable arm 401 is rotated and connected to the mounting base 309 and the movable base 402, in conjunction with the fixed knob. The spatial position of the cutting blade 408 can be flexibly adjusted to meet the cutting requirements of different angles. By rotating the handle 409, the bidirectional lead screw 404 in the adjustment frame 403 is rotated, so that the two threaded moving frames 406 move synchronously along the auxiliary rod 405, thereby accurately adjusting the distance between the two cutting frames 407. The scale line 410 on the surface of the adjustment frame 403 provides a visual reference for the distance adjustment, making it easy for operators to quickly and accurately set the cutting size. During the cutting process, the auxiliary rod 405 ensures the stability of the movement of the moving frames 406 and avoids the cutting blade 408 shaking, which affects the cutting accuracy. Finally, it achieves accurate and efficient cutting of paper packaging boxes.
