Description
Technical Field
[0001] This utility model relates to the field of flattening devices, and more specifically to a flattening device for a folding machine. Background Technology
[0002] The advent of automatic folding machines has improved production efficiency, but it has also brought new challenges, such as how to effectively flatten paper that has been folded multiple times. The flattening device used in folding machines can ensure that each sheet of paper reaches the required flatness before entering the next process, thereby improving the appearance and quality of the final product, and can effectively avoid the problem of low production efficiency caused by uneven paper folding or paper jams.
[0003] Existing flattening devices cannot effectively hold the paper to be flattened in a stable position. This instability causes the paper to easily shift or become misaligned during the flattening process, which may lead to the paper breaking or being damaged, seriously affecting the flattening effect and the quality of the paper.
[0004] In addition, existing flattening devices have significant limitations when handling paper of different thicknesses. Due to the lack of a flexible and convenient adjustment mechanism, users often find it difficult to accurately control the flattening thickness according to actual needs. This not only increases the difficulty of operation but also reduces work efficiency, making the flattening process cumbersome and time-consuming.
[0005] To address the aforementioned problems, this application provides a flattening device for a folding machine. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flattening device for a folding machine to solve the problems existing in the background art.
[0007] This utility model provides the following technical solution: a flattening device for a folding machine, including a housing assembly and a pasting assembly installed inside the housing assembly, a power assembly installed below the inner wall of the housing assembly, a limit assembly provided above the power assembly, and an adjustment assembly provided above the limit assembly;
[0008] Preferably, the housing assembly includes a main housing and support feet, wherein the support feet are fixedly installed at the four corners of the main housing.
[0009] Preferably, the bonding assembly includes a rotating roller and a flattening plate, wherein the rotating roller is fixedly installed at the bottom inlet and outlet ends of the main housing, and the flattening plate is disposed between the rotating rollers and fixedly installed in the bottom inner cavity of the main housing. At this time, the paper sheet to be flattened passes between the rotating rollers and is further flattened by the flattening plate.
[0010] Preferably, the power assembly includes a rotary motor, a rotary gear, a transmission belt, a first rotary rod, a first flattening roller, and a limiting plate. The rotary motor is fixedly installed on the side wall of the main housing. The rotary motor drive shaft is fixedly sleeved on the rotary gear. The transmission belt is wound between the two rotary gears. The rotary gear is fixedly sleeved on the first rotary rod. The first rotary rod is fixedly sleeved on the first flattening roller and the rotary gear. Limiting plates are provided at both ends of the first flattening roller. The limiting plates are rotatably sleeved at both ends of the first rotary rod. At this time, the rotary motor drive shaft drives the rotary gear, which in turn drives the rotary gear on the other side to rotate through the transmission action of the transmission belt. At this time, the first rotary rod and the first flattening roller are driven to rotate in the same direction.
[0011] Preferably, the limiting assembly includes a connecting rod, a contracting arm, a rotary spring, a second rotary rod, a second flattening roller, a pulley, and an annular groove. The main housing has an annular groove on its inner wall near the pulley. The connecting rod is fixedly mounted on the inner wall of the main housing. The upper end of the contracting arm is rotatably sleeved with the connecting rod. The rotary spring is fixedly mounted between the contracting arms and movably sleeved with the connecting rod. The end of the rotary spring away from the connecting rod is rotatably sleeved with the second rotary rod. The second flattening roller is disposed between the contracting arms and fixedly sleeved with the second flattening roller. The right end of the second rotary rod is rotatably sleeved with the pulley. The pulley is engaged in the annular groove. At this time, the paper is drawn between the second and first flattening rollers under the drive of the first flattening roller. Under the action of the rotary spring, the pulley moves along the engagement point with the annular groove. The contracting arm rotates and contracts towards the center along the axis of the connecting rod, driving the second flattening roller downwards to compress it, thus effectively limiting and fixing the paper passing between the first and second flattening rollers.
[0012] Preferably, the adjustment assembly includes a knob, a first bevel gear, a second bevel gear, a threaded screw, a moving block, an adjusting arm, and a slider. The knob is rotatably engaged with the side wall of the main housing. The left end of the knob passes through the side wall of the main housing and is fixedly sleeved with the first bevel gear. The first bevel gear meshes with the second bevel gear. One end of the second bevel gear is rotatably engaged with the inner wall of the main housing, and the other end is fixedly sleeved with the threaded screw. The threaded screw is threadedly sleeved with the moving block. A slider is fixedly installed on the side wall of the moving block near the main housing. The slider is slidably connected to the main housing. Adjusting arms are fixedly installed on both sides of the bottom of the moving block. The adjusting arms are positioned above the second rotating rod. When it is necessary to adjust the flattening thickness of different papers, rotating the knob causes the threaded screw to rotate through the meshing relationship between the first bevel gear and the rotating spring. Subsequently, under the threaded meshing action between the threaded screw and the adjusting arm, the moving block moves up and down along the engagement point between the slider and the main housing. The adjusting arm is moved up and down, thereby adjusting and limiting the second rotating rod and the second flattening roller, and thus adjusting the flattening thickness.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] When the device is running, the paper is fed between the second and first flattening rollers. Under the action of the rotating spring, the pulley moves along the engagement point with the annular groove. The retracting arm rotates and retracts towards the center along the axis of the connecting rod, driving the second flattening roller to compress downwards. This effectively limits and fixes the paper passing between the flattening rollers, preventing misalignment during the flattening process that could cause the paper to break. When it is necessary to adjust the flattening thickness of different papers, the knob is rotated. Through the meshing transmission between the gears, the screw is driven to rotate. Subsequently, through the meshing action of the screw, the moving block and the adjusting arm move up and down, thereby adjusting the flattening thickness. Attached Figure Description

At this time, driven by the rotary motor 301, the paper is effectively flattened by the action of the first flattening roller 305, the second flattening roller 405 and the adjusting arm 506. When it is necessary to adjust the flattening thickness of different papers, by rotating the knob 501, the threaded screw 504 is rotated through the meshing relationship between the first bevel gear 502 and the rotary spring 403. Subsequently, under the threaded meshing action between the threaded screw 504 and the adjusting arm 506, the moving block 505 is driven to move up and down along the engagement point between the slider 507 and the main housing 101. The adjusting arm 506 is driven to move up and down, thereby adjusting and limiting the second rotating rod 404 and the second flattening roller 405, and thus adjusting the flattening thickness of the paper.
