Abstract
Description
Technical Field
[0001] This utility model relates to a paper threading and traction device for printing paper, belonging to the technical field of traction equipment. Background Technology
[0002] In the flexible packaging industry, printing presses are used to print various types of paper and film. These presses enable high-quality, high-volume printing and are widely used in packaging, labeling, and other fields. However, when printing thin paper, paper breaks are prone to occur due to factors such as unstable temperature, humidity, and tension. After a break, multiple operators are required to work together to re-feed the paper according to the machine's paper feeding route. A search revealed that Chinese patent CN208324487U discloses a fully automatic printing press. In this patent, the printing process, from top to bottom, consists of an inking roller, an inking roller, a printing plate cylinder, and an impression cylinder. The printing plate cylinder holds the printing plate, so the paper to be printed passes between the printing plate cylinder and the impression cylinder. The inked printing plate cylinder performs the printing. The ink in the ink fountain is transferred by the ink fountain roller, then passed through the inking roller and the inking roller for even distribution before being transferred to the inking roller. The inking roller finally applies ink to the printing plate on the printing plate cylinder, thus achieving the printing process. However, in this patent, if the paper breaks during the printing process, the equipment needs to be stopped immediately, and the broken paper needs to be manually moved around the unpowered roller to the powered roller. The whole process takes a long time and affects production efficiency. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a paper feeding and traction device for printing paper, which can complete the paper feeding work after the paper breaks and improve production efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] A paper feeding and pulling device for printing paper includes:
[0006] Frame;
[0007] A first rotating pressure roller is rotatably mounted on the frame.
[0008] At least one transition rotary roller is rotatably mounted on the frame;
[0009] A traction device, comprising a sliding seat, a sliding block, and a traction roller, wherein the sliding seat is mounted on the frame, the sliding block is slidably fitted on the sliding seat, and the traction roller is mounted on the sliding block;
[0010] A traction channel suitable for the passage of printing paper is provided between the first rotating pressure roller and the traction roller. The sliding block is slidably mounted on the sliding seat and drives the traction roller to move to adjust the distance between the traction roller and the first rotating pressure roller. The traction roller is adapted to rotate to drive the printing paper through the traction channel.
[0011] Furthermore, the sliding seat is mounted on the frame by at least one fastening bolt.
[0012] Furthermore, to facilitate the sliding of the sliding block, the sliding seat is provided with a sliding channel and a slide rail.
[0013] Furthermore, the sliding block is provided with a sliding element that is adapted to the slide rail.
[0014] Furthermore, in order to control the movement of the sliding block, the traction device also includes a drive cylinder, which is mounted on the sliding seat. The movable end of the drive cylinder is connected to the sliding block, and the drive cylinder is adapted to drive the sliding block to slide on the sliding seat.
[0015] Furthermore, the traction device also includes a drive motor, the movable end of which is connected to the traction roller, and the drive motor is adapted to drive the traction roller to rotate.
[0016] Furthermore, in order to adjust the speed of the drive motor, a frequency converter is also installed on the drive motor. The frequency converter is adapted to adjust the speed of the drive motor, thereby adjusting the speed of the traction roller.
[0017] Furthermore, the frequency converter is equipped with a control knob suitable for controlling the output frequency of the frequency converter.
[0018] After adopting the above technical solution, this utility model has the following beneficial effects:
[0019] 1. In this utility model, the printing paper is passed through the traction channel between the first rotating pressure roller and the traction roller. The drive cylinder is started, and the extension and retraction of the drive cylinder causes the sliding block to slide on the sliding seat, thereby adjusting the distance between the traction roller and the first rotating pressure roller so that the printing paper can adhere to the first rotating pressure roller. The drive motor is started to drive the traction roller to rotate. The rotation of the traction roller causes the printing paper to move along the traction channel, realizing the traction of the paper, and then it is carried out by the transition rotating roller.
[0020] 2. In this utility model, in order to adapt to different paper feeding speed requirements, the output frequency of the frequency converter is set by the control knob on the frequency converter, thereby realizing precise control of the drive motor speed and making the paper traction process more stable.

[0024] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0025] like Figure 1-3 As shown, a paper feeding and pulling device for printing includes:
[0026] Frame 1;
[0027] The first rotating pressure roller 2 is rotatably mounted on the frame 1;
[0028] Three transition rotating rollers 3 are rotatably mounted on the frame 1;
[0029] The traction device includes a sliding seat 41, a sliding block 42 and a traction roller 43. The sliding seat 41 is mounted on the frame 1, the sliding block 42 is slidably mounted on the sliding seat 41, and the traction roller 43 is mounted on the sliding block 42.
[0030] A traction channel suitable for the passage of printing paper is provided between the first rotating pressure roller 2 and the traction roller 43. The sliding block 42 is slidably fitted on the sliding seat 41 and drives the traction roller 43 to move to adjust the distance between the traction roller 43 and the first rotating pressure roller 2. The traction roller 43 is adapted to rotate to drive the printing paper through the traction channel.
[0031] In this embodiment, the traction roller 43 can be a traction rubber roller. The rubber roller can effectively increase the friction between the traction roller 43 and the printing paper, thereby improving the traction effect and stability of the paper. The rubber roller is usually made of a highly elastic material and has good elasticity, which can effectively protect the printing paper during traction and prevent the printing paper from being damaged.
[0032] Specifically, such as Figure 2-3 As shown, the sliding seat 41 is mounted on the frame 1 by two fastening bolts 411.
[0033] Specifically, such as Figure 2-3 As shown, the sliding seat 41 is provided with a sliding channel 412 and a slide rail is provided on the sliding seat 41.
[0034] Specifically, the sliding block 42 is provided with a sliding element that is adapted to the slide rail.
[0035] Specifically, such as Figure 2-3 As shown, the traction device also includes a drive cylinder 44, which is mounted on a sliding seat 41. The movable end of the drive cylinder 44 is connected to a sliding block 42, and the drive cylinder 44 is adapted to drive the sliding block 42 to slide on the sliding seat 41.
[0036] In this embodiment, by driving the piston rod of the cylinder 44, the sliding block 42 can be easily controlled to move, thereby driving the traction roller 43 to move, thus changing the size of the traction channel to adapt to different specifications of printing paper.
[0037] Specifically, such as Figure 1 As shown, the traction device also includes a drive motor 45, the movable end of which is connected to the traction roller 43, and the drive motor 45 is adapted to drive the traction roller 43 to rotate.
[0038] Specifically, such as Figure 1 As shown, a frequency converter 7 is also installed on the drive motor 45. The frequency converter 7 is suitable for adjusting the speed of the drive motor 45, thereby adjusting the speed of the traction roller 43.
[0039] Specifically, such as Figure 1 As shown, the inverter 7 is equipped with a control knob 8 suitable for controlling the output frequency of the inverter 7.
[0040] In this embodiment, the printing paper is passed through the traction channel between the first rotating pressure roller 2 and the traction roller 43. The drive cylinder 44 is activated, and the extension and retraction of the drive cylinder 44 causes the sliding block 42 to slide on the sliding seat 41, thereby adjusting the distance between the traction roller 43 and the first rotating pressure roller 2 so that the printing paper can adhere to the first rotating pressure roller 2. The drive motor 45 is activated to drive the traction roller 43 to rotate. The rotation of the traction roller 43 causes the printing paper to move along the traction channel, realizing the traction of the paper, which is then carried out by the transition rotating roller 3.
[0041] To adapt to different paper feeding speed requirements, the output frequency of the inverter 7 is set by the control knob 8 on the inverter 7, thereby achieving precise control of the drive motor speed of 45, making the paper traction process more stable.
[0042] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
