Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paper feeding mechanisms for flexible packaging paper, specifically a paper feeding mechanism for high-speed packaging of flexible packaging paper. Background Technology
[0002] The paper feeding mechanism for high-speed packaging of flexible packaging paper is the core device responsible for the precise feeding of flexible packaging paper (such as laminated cigarette box paper, thin composite packaging paper, etc.) in high-speed packaging production lines for flexible packaging cigarette boxes, etc. Its core function is to draw out the packaging paper from the unwinding mechanism (base paper roll) and feed the paper to subsequent cutting, forming and other processes at a set speed (usually adapted to the packaging rhythm of hundreds to thousands of times per minute) through structures such as guide rollers, tension control components, and correction devices.
[0003] However, currently, the industry still generally uses a guide roller-based conveying mode for feeding coated cigarette box paper. This mode relies on the friction between the guide roller and the paper surface to drive the paper forward, in order to match the production rhythm of high-speed packaging lines. But this traditional method has obvious drawbacks: On the one hand, during long-term high-speed operation, the continuous friction between the guide roller and the coated cigarette box paper will accumulate heat, causing the roller surface temperature to gradually rise. The BOPP and other coating materials on the surface of the cigarette box paper have low melting points, and high temperatures can easily soften or even partially melt the coating, resulting in a "sticking to the roller" phenomenon. This not only damages the coating on the paper surface and causes scratches, but may also cause paper conveying to stall, affecting the subsequent cutting and forming accuracy. On the other hand, during storage and unwinding, the surface of coated cigarette box paper is prone to adhering to fine dust and fiber debris from the environment. If it is directly conveyed through the guide roller, these impurities will be crushed between the paper and the roller surface, which may aggravate roller surface wear and the generation of static electricity, and may also form indentations or dot-like defects on the paper surface. In severe cases, it may also lead to a decrease in the adhesion between the subsequent coating layer and the paper substrate. Utility Model Content

Detailed Implementation
[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0017] Please see Figure 1-4 As shown, a paper feeding mechanism for high-speed packaging of flexible paper is provided. The paper feeding mechanism includes a mounting frame 1, a belt conveyor body 2 is installed inside the mounting frame 1, and a support part 3 is fixedly connected to the top of the mounting frame 1. The mounting bracket 1 facilitates the installation and fixing of the belt conveyor body 2, which is composed of a transmission structure and belt, while the support part 3 is used for subsequent transmission support work.

[0019] Motor 402 drives the paper guide roller 401 to rotate, and the paper guide roller 401 is used to make frictional contact with the packaging paper to perform paper feeding. The exhaust hole 403 achieves two effects: one is to help the paper guide roller 401 dissipate heat, and the other is to help blow away the floating dust on the surface of the conveyed packaging paper to reduce its impact on subsequent processing. The transmission assembly 4 also includes a transmission rod 404 fixed to the output end of the motor 402. One end of the transmission rod 404 is rotatably connected to the inside of the positioning frame 31 through a bearing.

A second meshing wheel 407 is meshed with the bottom of the inner cavity of the toothed belt 406.
[0020] When the motor 402 is turned on, the transmission rod 404 will drive the first meshing wheel 405 to rotate. When the first meshing wheel 405 rotates, it will mesh with the toothed belt 406 to rotate. As the toothed belt 406 rotates, it will mesh with the second meshing wheel 407 to rotate, thereby assisting the subsequent drive work.
[0021] The transmission assembly 4 also includes a support rod 408 fixed to one side of the guide roller 401, a second meshing wheel 407 fixed to the surface of the support rod 408, and one end of the support rod 408 rotatably connected to the inner wall of the positioning frame 31 through a bearing.
[0022] One end of the support rod 408 is rotatably connected to the inside of the positioning frame 31, and the mating surface is fixed to the second meshing wheel 407, which can assist in the rotation of the transmission guide roller 401.
[0023] The transmission assembly 4 also includes a rubber guide plate 409 fixed inside the paper guide roller 401, and an air supply unit 410 is fixedly connected to one side of the paper guide roller 401.
[0024] The rubber guide plate 409 can provide a certain buffer when the paper guide roller 401 comes into contact with the paper during rotation, while the air supply unit 410 is used to guide the airflow inside the paper guide roller 401 to facilitate subsequent heat dissipation.
[0025] The air supply unit 410 includes a connecting shell 411. A first support frame 412 is fixedly connected to one side of the inside of the connecting shell 411. One side of the connecting shell 411 is fixedly connected to the paper guide roller 401. A fan blade 413 is fixedly connected to one side of the rubber guide plate 409. A filter plate 414 is inserted into the inside of the connecting shell 411.
[0026] The first support frame 412 inside the connecting housing 411 provides convenient support to one side of the rubber guide plate 409 inside the paper guide roller 401. Meanwhile, the fan blade 413 is fixedly connected between the rubber guide plate 409 and the first support frame 412 to facilitate subsequent heat dissipation. The filter plate 414 is inserted into the connecting housing 411 and fixed with screws, allowing it to filter dust from the gas drawn in by the fan blade 413. The air supply unit 410 also includes a second support frame 415 fixed to one side of the connecting shell 411. One end of the second support frame 415 is rotatably connected to a drive rod 416, and one end of the drive rod 416 is rotatably connected to the positioning frame 31 through a bearing.
[0027] The second support frame 415 is fixed to the outside of the connecting shell 411, and the drive rod 416, which is rotatably connected to the positioning frame 31, can provide stable support for one end of the guide roller 401.
[0028] The support part 3 includes a frame 32 fixed to the top of the mounting bracket 1. A hydraulic cylinder 33 is fixedly connected to the bottom of the frame 32. The piston end of the hydraulic cylinder 33 is fixedly connected to the positioning bracket 31. Limiting rods 34 that slide inside the frame 32 are fixedly connected to both sides of the top of the positioning bracket 31.
[0029] The frame 32 provides convenient support for the hydraulic cylinder 33, and the fixing of the piston end of the hydraulic cylinder 33 to the positioning frame 31 facilitates the adjustment and descent of the motor 402 and the paper guide roller 401. The sliding connection between the limiting rod 34 and the frame 32 can improve the stability of the positioning frame 31 during the up and down movement.
[0030] The transmission assembly 4 also includes an extension frame 417 rotatably connected to the surfaces of the support rod 408 and the drive rod 416, and a pressure roller 418 rotatably connected between the two extension frames 417; the extension frame 417 and the pressure roller 418 can help to press down the paper box during transmission and prevent the paper box from curling up after passing the guide roller 401.
[0031] Working principle: First, the packaging paper to be fed is placed on the belt conveyor body 2. As the belt is conveyed, the positioning frame 31 is driven by the hydraulic cylinder 33 to lower the motor 402. Then, the output end of the motor 402 is turned on, driving the transmission rod 404 to rotate. At this time, the transmission rod 404 will drive the first meshing wheel 405 to rotate. When the first meshing wheel 405 rotates, it will mesh with the toothed belt 406. As the toothed belt 406 rotates, it will mesh with the second meshing wheel 407 to rotate. At this time, the second meshing wheel 407 will drive the support rod 408 to directly drive the guide roller 401 to rotate. However, with the drive of the hydraulic cylinder 33, the guide roller 401 will contact the paper box to generate friction and achieve high-speed conveying. At the same time, the guide roller 401 will contact the paper box to generate friction and achieve high-speed conveying. When roller 401 rotates, it drives connecting shell 411, second support frame 415, and drive rod 416 to rotate inside positioning frame 31. At this time, fan blades 413 located inside guide roller 401 will draw negative pressure airflow from the outside through filter plate 414 into guide roller 401, and blow away floating dust on packaging paper through multiple exhaust holes 403, while reducing the heat generated by friction of guide roller 401. Fan blades 413 rotate with guide roller 401, and the airflow direction is dynamically matched with the rotation speed of guide roller 401. The higher the rotation speed, the stronger the airflow, and the dust removal and heat dissipation effect increases synchronously with the speed of the machine. Finally, pressure roller 418 is used to prevent the paper box from curling after being rubbed by guide roller 401, thus completing the conveying work.
