[0002] In the current booming development of the packaging industry, color boxes, as a key carrier of product packaging, are facing increasing market demand. Consumers' stringent requirements for the exquisite appearance and clear printing of color boxes have made the quality and efficiency of color box printing a core element of industry competition. As the starting point of the color box printing process, the operation of the paper feeding device directly affects the success or failure of the entire printing process.

[0003] However, existing paper feeding devices for color box printing that prevent paper jams may cause paper jams during transport due to the paper's tendency to wrinkle. This affects the efficiency of paper transport, reduces paper processing efficiency, and impacts subsequent paper processing. Utility Model Content

[0004] The purpose of this utility model is to provide a paper feeding device for color box printing that prevents paper jams. By setting up a smoothing mechanism, it solves the problem that paper may easily wrinkle, which may cause paper jams during transmission, affecting the efficiency of paper transmission, reducing the efficiency of paper processing, and affecting subsequent paper processing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a paper feeding device for color box printing that prevents paper jams, including a working box, on which an adjustment mechanism and a smoothing mechanism are provided;

[0007] The adjustment mechanism includes limiting slide grooves respectively opened on the front and rear sides of the work box. The inner walls of the two limiting slide grooves are slidably connected to sliders. A fixed plate is fixedly connected between the two sliders. The smoothing mechanism includes two bidirectional hinge blocks fixedly connected to the bottom of the fixed plate. Two hinge rods are hinged on the two bidirectional hinge blocks. Two fixed supports are provided at the bottom of the fixed plate. The top of the two fixed supports is provided with trapezoidal slide grooves. The inner walls of the two trapezoidal slide grooves are slidably connected to two hinge blocks. Several hinge rods are respectively hinged to several hinge blocks.

[0008] Furthermore, the inner wall of the work box is provided with a conveying component, and paper inlets are provided on both the left and right sides of the work box.

[0009] Furthermore, a threaded rod is rotatably connected to the inner wall of the limiting slide groove located on the front side. The top of the threaded rod passes through the slider located on the front side, and the threaded rod is threadedly connected to the slider located on the front side. The top of the threaded rod extends to the outside of the working box, and the threaded rod is rotatably connected to the working box.

[0010] Furthermore, a handle is fixedly connected to the outer wall of the threaded rod, and a slide rod is fixedly connected to the inner wall of the limiting slide groove located on the rear side. The slide rod passes through the slider located on the rear side, and the slide rod is slidably connected to the slider located on the rear side.

[0011] Furthermore, a ratchet gear is fixedly connected to the outer wall of the threaded rod, a fixing block is fixedly connected to the top of the work box, a telescopic rod is fixedly connected to the left side of the fixing block, a limit block is fixedly connected to the left side of the telescopic rod, and the limit block is adapted to the ratchet gear.

[0012] Furthermore, a spring is fitted on the outer wall of the telescopic rod, with the right side of the spring fixedly connected to the fixing block and the left side of the spring fixedly connected to the limiting block.

[0013] Furthermore, the inner walls of the two trapezoidal slides are fixedly connected with fixed rods, the two fixed rods respectively pass through several hinge blocks, the two fixed rods are slidably connected to several hinge blocks respectively, and the several hinge blocks are respectively connected to the two fixed rods.

[0014] Furthermore, two springs are fitted on the outer walls of both fixed rods. The sides of several springs that are far apart from each other are fixedly connected to two fixed brackets, and the sides of several springs that are close to each other are fixedly connected to several hinge blocks. Several cylindrical rods are rotatably connected between the two fixed brackets, and rollers are fixedly connected to the outer walls of the several cylindrical rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a smoothing mechanism, when the fixed plate moves downward, the fixed plate drives the two fixed supports downward through the two hinge rods on the two bidirectional hinge blocks. At this time, the two fixed supports drive the rollers downward through the cylindrical rods, thereby squeezing the paper. The squeezing force is transmitted to the two fixed supports through the rollers, so that the two hinge rods drive the two hinge blocks to slide on the trapezoidal slide and the fixed rod respectively. At this time, the two hinge blocks squeeze the two springs. The two springs generate elastic force, thereby squeezing the paper. Under the action of the springs, the squeezing force on the paper is prevented from being too large, which could cause the paper to break. After the squeezing force is adjusted by the threaded rod, the conveying component is then started to let the paper enter through the paper inlet on the right and then be led out from the paper inlet on the left. The cooperation between several rollers and the conveying component smooths out the wrinkles of the paper, thereby correcting the overall flatness of the paper, improving the smoothness and stability of the paper feeding, reducing the friction and collision between the paper and the paper feeding channel components, thereby reducing the risk of paper jams and reducing printing defects caused by uneven paper.

[0017] 2. By setting an adjustment mechanism, when the threaded rod rotates clockwise, the rotation of the ratchet is restricted by the action of the limit block. By pulling the limit block to the right, the telescopic rod and spring are compressed, releasing the limit block from restricting the ratchet. Then, rotating the handle clockwise causes the handle to drive the front slider to slide down the inner wall of the limit groove via the threaded rod. The front slider drives the rear slider to move on the slide rod via the fixed plate. Because the threaded rod and slide rod are designed to be parallel, the fixed plate moves downward via the two sliders. When rotating counterclockwise... When the threaded rod is rotated, the arc-shaped surface of the ratchet on the threaded rod will press against the limiting block, causing the limiting block to move to the right and press against the telescopic rod and spring one. At this time, spring one generates elastic force, and the threaded rod will no longer be restricted by the limiting block, thereby raising the height of the fixing plate. This allows for automatic adjustment according to the actual situation, ensuring that the paper always maintains appropriate tension and keeps the paper moving in a straight line during the conveying process. This reduces paper deviation or shaking caused by uneven tension, thereby ensuring that the paper can accurately enter the printing area, improving printing quality, and reducing the risk of paper jams caused by inaccurate paper positioning.

The left side of the spring 2111 is fixedly connected to the limit block 2110. By setting the adjustment mechanism 2, the paper can be automatically adjusted according to the actual situation, so that the paper always maintains an appropriate tension and keeps the paper moving in a straight line during the conveying process. This reduces the paper deviation or shaking caused by uneven tension, thereby ensuring that the paper can accurately enter the printing area, improving the printing quality and reducing the risk of paper jams caused by inaccurate paper position.

[0030] The smoothing mechanism 3 includes two bidirectional hinge blocks 311 fixedly connected to the bottom of the fixed plate 213. Each of the two bidirectional hinge blocks 311 has two hinge rods 312 hinged to it. The bottom of the fixed plate 213 has two fixed supports 313, each with a trapezoidal groove 314 at its top. The inner walls of each trapezoidal groove 314 are slidably connected to two hinge blocks 315. Several hinge rods 312 are hinged to several hinge blocks 315. The inner walls of each trapezoidal groove 314 are fixedly connected to two fixing rods 316, which pass through several hinge blocks 315 and are slidably connected to them. The several hinge blocks 315... Two fixed rods 316 are respectively attached to the outer walls of the two fixed rods 316, and two springs 317 are respectively fitted on the outer walls of the two fixed rods 316. The outer sides of the springs 317 that are far apart from each other are respectively fixedly connected to two fixed brackets 313, and the outer sides of the springs 317 that are close to each other are respectively fixedly connected to several hinge blocks 315. Several cylindrical rods 318 are rotatably connected between the two fixed brackets 313, and rollers 319 are fixedly connected to the outer walls of the cylindrical rods 318. By setting up the smoothing mechanism 3, the overall flatness of the paper is corrected, improving the smoothness and stability of paper feeding, reducing the friction and collision between the paper and the paper feeding channel components, thereby reducing the risk of paper jams and reducing printing defects caused by uneven paper.

[0031] A specific application of this embodiment is as follows: In use, paper is inserted into the conveying assembly 111 through the right paper inlet 112, and then the paper is pulled out through the left paper inlet 112. When the threaded rod 214 rotates clockwise, the rotation of the threaded rod 214 is restricted by the action of the limiting block 2110 restricting the rotation of the ratchet 217. By pulling the limiting block 2110 to the right, the telescopic rod 219 and the spring 2111 are squeezed, causing the limiting block 2110 to release the restriction on the ratchet 217. Then, the handle 215 is rotated clockwise, and the handle 215 passes through the threaded rod 219. 14 drives the front slider 212 to slide and move downward on the inner wall of the limiting groove 211. The front slider 212 drives the rear slider 212 to move on the slide rod 216 through the fixing plate 213. Because the threaded rod 214 and the slide rod 216 are designed in parallel, the fixing plate 213 is driven downward through the two sliders 212. When the threaded rod 214 is rotated counterclockwise, the arc-shaped surface of the ratchet 217 on the threaded rod 214 will press against the limiting block 2110, causing the limiting block 2110 to move to the right, pressing against the telescopic rod 219 and the spring 2111. When the spring 2111 generates elastic force, the threaded rod 214 will no longer be restricted by the limit block 2110, thus raising the height of the fixed plate 213. When the fixed plate 213 moves downward, the fixed plate 213 drives the two fixed supports 313 downward through the two hinge rods 312 on the two bidirectional hinge blocks 311. At this time, the two fixed supports 313 drive the rollers 319 downward through the cylindrical rods 318, thereby squeezing the paper. The squeezing force is transmitted to the two fixed supports 313 through the rollers 319, thereby causing the two hinge rods 312 to drive the two hinge blocks 311 respectively. 5. The paper slides on the trapezoidal slide 314 and the fixed rod 316. At this time, the two hinge blocks 315 press the two springs 317 respectively. The two springs 317 generate elastic force, thereby pressing the paper. Under the action of the springs 317, the pressure on the paper is prevented from being too great, which would cause the paper to break. After the pressure is adjusted by the threaded rod 214, the conveying assembly 111 is then started to put the paper in through the right paper inlet 112 and then out through the left paper inlet 112. The wrinkles of the paper are smoothed out by the cooperation between the several rollers 319 and the conveying assembly 111.
