Description

Technical Field

[0001] This utility model relates to the field of coated paper spreading technology, and more specifically, to a coated paper spreading device. Background Technology

[0002] A coated paper spreading device is a piece of equipment used to process coated paper. Its main purpose is to flatten the coated paper, eliminate curls or wrinkles, and ensure its smoothness. Coated paper is a material with a plastic film coated on its surface, commonly used in packaging, printing, and other fields. By using mechanical or pneumatic methods to effectively flatten coated paper, production efficiency and product quality are improved, making it widely applicable in the packaging and printing industries.

[0003] Chinese Patent Announcement No. CN220131513U discloses a sheet coating flattening device. This device guides the sheet coating through the cooperation of a guide roller and a movable plate. A belt connects a second drive wheel and a second movable wheel, allowing a second motor to drive the second movable wheel and a first flattening roller to rotate. The cooperation between the second roller and the first flattening roller flattens the sheet coating. A hydraulic rod adjusts the height of a fixed plate, and a third motor and a third transmission shaft drive the second flattening roller to rotate, thus fully unfolding the sheet coating. A belt connects a first drive wheel and a first movable wheel, allowing a first motor to drive the first transmission shaft and a piercing roller to rotate, piercing and flattening the sheet coating, thereby expelling air bubbles from inside the sheet coating.

[0004] After the coated paper is flattened, it needs to be rewound for storage, transportation and subsequent processing. The device in the above solution can only flatten the coated paper. When rewinding, since the coated paper raw material is usually wide, the edges are prone to curling, which affects the overall flatness of the coated paper.

[0005] Therefore, a coating paper spreading device is proposed to address the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-4 A paper coating spreading device includes two parallel fixed frames 1 and a flattening assembly 2. Roller shaft 3 and roller shaft 4 are rotatably connected between the two fixed frames 1. Roller shaft 3 and roller shaft 4 are arranged in parallel. The flattening assembly 2 is located above roller shaft 3 and roller shaft 4. A drive assembly 5 is installed on the outside of one of the fixed frames 1. The drive assembly 5 is used to drive roller shaft 3 and roller shaft 4 to rotate. An edge pressing assembly 7 is provided on the top of both fixed frames 1. The edge pressing assembly 7 includes a vertical rod 71 and an edge pressing roller 73. The bottom end of the vertical rod 71 is fixedly installed on the top of the fixed frame 1. A movable rod 72 is rotatably connected to the top end of the vertical rod 71. The edge pressing roller 73 rotates up and down with the movable rod 72 by gravity.

[0036] The device in this scheme is mainly used to flatten the coated paper and improve its flatness to facilitate the next processing step. The bottom ends of the two fixed frames 1 are fixed with brackets 6. The brackets 6 can lift the two fixed frames 1 so that they are arranged in parallel. Roller shaft 1 3 and roller shaft 2 4 are rotatably connected between the two fixed frames 1. Roller shaft 1 3 and roller shaft 2 4 are arranged in parallel. A drive assembly 5 is set on the outside of one of the fixed frames 1. The drive assembly 5 drives roller shaft 1 3 and roller shaft 2 4 to rotate. A flattening assembly 2 is also set between the two fixed frames 1. The flattening assembly 2 is located above roller shaft 1 3 and roller shaft 2 4. Through the pressing of the flattening assembly 2, roller shaft 1 3 and roller shaft 2 4, and the rotation of roller shaft 1 3 and roller shaft 2 4, the coated paper can be flattened and conveyed forward at the same time, so that it can be flattened continuously.

[0037] Meanwhile, edge pressing components 7 are set on both fixed frames 1. A movable rod 72 is rotatably connected to the top of the vertical rod 71, and an edge pressing roller 73 is installed at the end of the movable rod 72. Due to gravity, the edge pressing roller 73 always rotates downward. When the winding roller 9 rewinds the coated paper, the two edge pressing rollers 73 will overlap the edge of the rolled coated paper. Through gravity, they can always press against the edge of the coated paper to prevent curling, thereby improving the overall flatness of the coated paper after it is flattened.

[0038] Please see Figure 2The drive assembly 5 includes a motor 51, a driven gear 52 and a driven gear 53. The bottom ends of the two fixed frames 1 are fixedly mounted with brackets 6. One end of the roller shaft 3 and the roller shaft 4 extends through the fixed frame 1 to the outside. The driven gear 52 is fixedly mounted on one end of the roller shaft 3 and the driven gear 53 is fixedly mounted on one end of the roller shaft 4.

[0039] Motor 1 51 is fixedly installed on the outer end of the fixed frame 1. The output end of motor 1 51 is keyed to a drive gear 54. The drive gear 54 meshes with both driven gear 1 52 and driven gear 2 53. Motor 1 51 drives both driven gear 1 52 and driven gear 2 53 to rotate through the drive gear 54.

[0040] The drive assembly 5 in this solution is mainly used to drive roller 3 and roller 4. Motor 51 is fixed to the outer end of one of the fixed frames 1, and the ends of roller 3 and roller 4 near motor 51 extend through the fixed frame 1. A driven gear 52 is fixed to the extended end of roller 3, and a driven gear 53 is fixed to the extended end of roller 4. A drive gear 54 is keyed to the output end of motor 51. Both sides of the drive gear 54 are simultaneously engaged with driven gears 52 and 53. Therefore, when motor 51 drives drive gear 54 to rotate, drive gear 54 will simultaneously drive driven gears 52 and 53 to rotate, thereby causing roller 3 and roller 4 to rotate, flattening the coated paper and conveying it forward.

[0041] Please see Figure 3 The flattening assembly 2 includes a movable roller shaft 21 and two threaded blocks 24. Both ends of the movable roller shaft 21 are rotatably connected to movable blocks 22. The top of the movable blocks 22 is rotatably connected to a screw 23. The outer end of the fixed frame 1 is provided with a movable groove 25 that matches the movable blocks 22. The movable blocks 22 and the movable groove 25 are slidably connected.

[0042] Two threaded blocks 24 are fixedly installed on the top of two fixed frames 1 respectively. The screw 1 23 is threadedly connected to the threaded block 24. The screw 1 23 drives the movable roller shaft 21 to move and adjust the distance between it and the roller shaft 1 3 and the roller shaft 2 4 by rotating.

[0043] In this design, the flattening assembly 2 is mainly used to cooperate with roller 1 3 and roller 2 4 to flatten the coated paper passing below the flattening assembly 2. The movable roller 21 is rotatably connected between two movable blocks 22. A screw 1 23 is rotatably connected to the top of the two movable blocks 22. At the same time, movable grooves 25 are opened at the outer ends of the two fixed frames 1. The movable grooves 25 match the movable blocks 22, allowing the movable blocks 22 to slide up and down inside the movable grooves 25. Meanwhile, at the top of the two fixed frames 1, that is, at the top of the movable grooves 25, threaded blocks 24 are fixed. This is matched with screw 23, so that screw 23 and threaded block 24 are threadedly connected. By rotating both screws 23 at the same time, screw 23 can drive movable block 22 to move up and down. Since movable roller shaft 21 is rotatably installed between the two movable blocks 22, the up and down moving movable block 22 will drive movable roller shaft 21 to move, thereby adjusting the distance between movable roller shaft 21 and roller shaft 3 and roller shaft 4. When dealing with coated paper of different thicknesses, it can be adjusted so that it can flatten coated paper of different thicknesses and specifications, thus improving its applicability.

[0044] Please see Figure 4 The pressing assembly 7 also includes a connecting rod 75, which is fixedly installed at one end of the pressing roller 73. A limit plate 74 is fixedly installed at the end of the pressing roller 73 near the connecting rod 75. An installation groove is opened at the end of the movable rod 72 away from the vertical rod 71. A threaded sleeve 76 is fixedly installed on the inner side wall of the installation groove. A screw 77 is fixedly connected at the end of the connecting rod 75 away from the pressing roller 73. The screw 77 is threadedly connected to the threaded sleeve 76.

[0045] The edge-pressing assembly 7 in this solution is mainly used to press the edge of the coated paper during rewinding to prevent curling. The vertical rod 71 is fixed to the fixing frame 1 and is installed vertically. A movable rod 72 is rotatably connected to the top of the vertical rod 71 via a bearing. The movable rod 72 can rotate. An installation groove is provided at the end of the movable rod 72 away from the vertical rod 71, and a threaded sleeve 76 is fixed to the inner wall of the groove. The edge-pressing roller 73 is cylindrical and is used to flatten the edge of the coated paper. A limiting plate 74 is fixed to one end of the edge-pressing roller 73. The limiting plate 74 is mainly used for positioning. When the edge-pressing roller 73 presses against the edge of the rolled coated paper, the limiting plate 74 can precisely abut against the side of the coated paper roll, thus positioning the edge-pressing roller 73. It also provides assistance when the edge-pressing roller 73 is adjusted.

[0046] A connecting rod 75 is fixed to one end of the pressing roller 73, and a screw 77 is fixedly connected to one end of the connecting rod 75. A knob is connected to the end of the screw 77. The screw 77 is threadedly connected to the threaded sleeve 76. When flattening coated paper of different widths, the position of its edge is also different. Therefore, the pressing roller 73 can be moved by rotating the screw 77 so that it can accurately press on the edge of the coated paper.

[0047] Due to gravity, the movable rod 72 and the pressure roller 73 will always tend to rotate downwards, so that the pressure roller 73 can press tightly against the edge of the coated paper. As the coated paper roll gets thicker, the pressure roller 73 and the movable rod 72 will also rotate upwards adaptively, so that it can always be located at the edge of the coated paper roll.

[0048] Please see Figure 1 and Figure 2 Two mounting plates 8 are fixedly installed on the inner side of each of the two mounting frames 1. A take-up roller 9 is rotatably connected between the two mounting plates 8. A motor 2 10 is fixedly installed on the outer end of one of the mounting frames 1. The output end of the motor 2 10 is connected to one end of the take-up roller 9 to drive the take-up roller 9 to rotate.

[0049] Two mounting plates 8 are fixed to the inner sides of two fixed frames 1 respectively. A take-up roller 9 is rotatably connected between the two mounting plates 8. The take-up roller 9 is mainly used to rewind the coated paper. The second motor 10 is fixed to the outer end of one of the fixed frames 1. The take-up roller 9 is the same as roller shaft 3 or roller shaft 4. One end extends through the mounting plate 8 to the outside and is connected to the output end of the second motor 10. When the second motor 10 starts to rotate, it can drive the take-up roller 9 to rotate and rewind the flattened coated paper.

[0050] Working principle: When using this device, firstly, the flattening component 2 needs to be adjusted according to the thickness of the coated paper. At the same time, rotating the screws 23 on both sides will cause the screws 23 to drive the movable block 22 to move up and down, thereby adjusting the distance between the movable roller 21 and rollers 3 and 4, so that it can handle coated papers of different thicknesses. Next, the position of the edge pressing roller 73 needs to be adjusted according to the width of the coated paper. By rotating the screw 77, the edge pressing roller 73 is moved to accurately press the edge of the coated paper. Then, the coated paper can be guided through the movable roller 21 and roller 3, and finally wound onto the take-up roller 9. Then, the motors 51 and 10 can be started to start the automatic flattening and rewinding. The two edge pressing rollers 73 will be placed on the edge of the rolled coated paper. Through gravity, they can always press the edge of the coated paper to prevent curling, thereby improving the overall flatness of the coated paper after flattening.
