Description

Technical Field

[0001] This utility model belongs to the field of paper production technology, specifically a leveling device for paper production. Background Technology

[0002] In paper production, leveling equipment (such as calenders, roller levelers, and thermal levelers) is a key piece of equipment to ensure the flatness, smoothness, and thickness uniformity of paper. By placing the paper between the rotating upper and lower pressure rollers in the roller leveler, the paper is squeezed and leveled by the upper and lower pressure rollers.

[0003] In existing technology, before entering the squeezing area of ​​the upper and lower pressure rollers, paper is affected by previous processes (such as stacking after drying) and the characteristics of the paper itself (thin paper has low stiffness, and the edge fibers of thick paper are easily deformed). Defects such as bending and warping are likely to occur at the corners of the paper. When paper with bent or warped corners enters the squeezing area between the rollers of the leveling equipment, the bending or warping at the corners will be forcibly pressed together. This not only makes it difficult to completely eliminate the original defects at the corners, but may also form permanent indentations at the corners of the paper due to local pressure concentration, affecting the flattening effect and flattening quality of the paper. Therefore, we propose a leveling equipment for paper production. Utility Model Content

Through the fixed connection between the drive motors and the upper rotating roller 201 and the lower rotating roller 200, the upper rotating roller 201 and the lower rotating roller 200 are driven to rotate synchronously. The controller simultaneously controls the working ends of the two sets of motors 207 to rotate synchronously. Through the transmission structure such as the main rod 1 inside the rotating column 206, the transmission belt 210, and gears, the two sets of rotating columns 206 on the upper frame 202 and the two sets of rotating columns 206 on the lower frame 204 rotate synchronously.

[0019] Example 3 Please refer to Example 2. Figures 1-5The front and back of the body 100 are provided with adjustment components for adjusting the height of the upper frame 202. The adjustment components include a protruding plate 300 fixed on the body 100 and a spiral plate 301 fixed on the surface of the upper frame 202. The top of the protruding plate 300 passes through the interior of the spiral plate 301.

[0020] In this embodiment, an upper rod and a lower rod are fixedly installed inside the upper pressure roller 101 and the lower pressure roller 104, respectively. The two ends of the lower rod are rotatably connected to the bracket 102. A lower bearing is sleeved on the outer side of both ends of the upper rod (the lower bearing is composed of an inner ring and an outer ring, etc., and the upper bearing is composed of an inner ring and an outer ring, etc., the inner ring is sleeved on the end of the upper rod, the outer wall of the outer ring is fixed to the outer ring of the upper bearing, and the inner ring of the upper bearing is fixedly connected to the bottom of the adjusting screw 106). The upper bearing is fixedly installed on the outer wall of the lower bearing. The adjusting screw 106 is threadedly connected inside the bracket 102. Furthermore, the bottom of the adjusting screw 106 extends into the interior of the upper bearing. When it is necessary to adjust the distance between the upper pressure roller 101 and the lower pressure roller 104 to accommodate different paper thicknesses, the operator rotates the adjusting screw 106 upwards or downwards. The adjusting screw 106 will move upwards or downwards along the bracket 102. The bottom of the adjusting screw 106 drives the upper bearing to move up and down. The upper bearing drives the lower bearing to move synchronously. The lower bearing then drives the upper rod to move up and down. Finally, the upper rod drives the upper pressure roller 101 to move up and down, thereby adjusting the distance between the upper pressure roller 101 and the lower pressure roller 104.

[0021] In this embodiment, a main motor 105 is fixedly mounted on the bracket 102, and the working end of the main motor 105 is fixedly connected to the lower rod. Both the upper and lower rods are fixedly equipped with upper gears 103 at one end, and the two sets of upper gears 103 mesh together.

[0022] Working principle and usage process of this utility model: When this utility model is in use, after the paper enters the equipment, it first comes into contact with multiple sets of conveyor belts 203 on the leveling mechanism. The multiple sets of conveyor belts 203 press the paper up and down for conveying. At the same time, the rotating columns 206 on the upper frame 202 and the lower frame 204 start to rotate. Multiple sets of soft bristles on the outside of the rotating columns 206 move accordingly, sweeping the curved and warped parts around the corners of the paper. During the leveling process, the multiple sets of conveyor belts 203 rotate synchronously, on the one hand driving the paper to be steadily conveyed to the right, and on the other hand, pressing and limiting the paper through the cooperation between the conveyor belts 203 to prevent the paper from shifting during the leveling process. After being processed by the leveling mechanism, the paper is then conveyed between the rotating upper pressure roller 101 and the lower pressure roller 104. The upper pressure roller 101 and the lower pressure roller 104 apply pressure to the paper to complete the final leveling operation. When the drive motor starts, its output shaft directly drives the upper rotating roller 201 and the lower rotating roller 200 to rotate. The rotation of the upper rotating roller 201 and the lower rotating roller 200 then drives the auxiliary roller 205 to rotate synchronously through the sleeved conveyor belt 203, thereby ensuring that the conveyor belt 203 is always in a taut state and runs stably, realizing the continuous conveying of paper and enabling the conveyor belt 203 to perform paper conveying operations. After the motor 207 is started, its output power is transmitted to the main rod 1. The main rod 1 transmits the power to the intermediate rod through the transmission belt 210. The rotation of the intermediate rod drives the right gear 209 at the end to rotate. Since the right gear 209 meshes with the left gear 208, the left gear 208 rotates accordingly and drives the main rod 2 to rotate. The rotation of the main rod 1, the main rod 2, and the intermediate rod eventually drives the rotating column 206 to rotate. At this time, multiple rotating columns 206 rotate synchronously, and the soft bristles on the outside of the rotating column 206 also rotate, thereby realizing the smoothing operation of the paper corner. When the height of the upper frame 202 needs to be adjusted, the operator can loosen the locking screw 302 by turning it outward, and then move the upper frame 202 upward or downward, so that the U-shaped plate 301 fixed on the upper frame 202 slides up and down along the convex plate 300 until the upper frame 202 is adjusted to a suitable height. Then, the locking screw 302 is turned towards the convex plate 300 to tighten it, thus fixing the upper frame 202 and adjusting the distance between the conveyor belt 203 on the upper frame 202 and the conveyor belt 203 on the lower frame 204 to adapt to the leveling requirements of paper of different thicknesses.

[0023] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
