Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and in particular to a tissue paper embossing device. Background Technology

[0002] Embossing on tissue paper is a process that presses raised and recessed patterns onto the surface of tissue paper. It combines functionality and aesthetics. The printed structure expands the water storage space, making it especially suitable for scenarios with high water absorption requirements, such as kitchen paper. The unprinted areas form air bubbles, increasing the fluffiness and softness of the paper, and it can still maintain its toughness after getting wet.

[0003] A search revealed Chinese patent publication number CN222844947U, which discloses an embossing device for producing cream tissues. This patent uses a servo motor to drive the main screw to rotate, and the threaded connection drives the printing plate to perform precise lifting and lowering movements. The printing plate moves smoothly along the inner wall of the limiting guide frame via a movable block, thereby performing precise embossing operations on the preheated tissues. However, this device has certain problems: it cannot effectively smooth the tissues before printing, and the tissues themselves may be uneven, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a paper towel embossing device to solve the above-mentioned problems.

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a paper towel embossing device includes a workbench 101, a conveying mechanism on the workbench 101, symmetrical support plates 102 fixed at the front and rear of the workbench 101, a top plate fixed at the upper end of the support plates 102, an mounting plate 302 between the symmetrical support plates 102, a pressure plate 501 fixed at the lower end of the mounting plate 302, and a smoothing mechanism on the mounting plate 302.

[0027] The smoothing mechanism includes two connecting arms 402, which are symmetrically and rotatably connected to both sides of the mounting plate 302. The symmetrical connecting arms 402 are V-shaped with their tips pointing upwards. A gear 401 is fixed to one end of each connecting arm 402 near the mounting plate 302, and the gears 401 on both sides mesh with each other. A fixing rod 403 is fixedly connected to the lower end of the connecting arm 402, and a heating tube 405 is fixed to the fixing rod 403. The heating tube 405 is spirally oriented along the axial direction of the fixing rod 403, and is rotatably connected to the fixing rod 403. There is a roller 404, which conveys the paper towel to the area below the mounting plate 302 via a conveying mechanism. The heating tube 405 heats the roller 404 to a suitable temperature. Then, the mounting plate 302 drives the pressure plate 501 to press down, causing the symmetrical rollers 404 to roll on the surface of the paper towel. At the same time, the connecting arm 402 rotates, causing the gears 401 on both sides to mesh with each other. Thus, the heated rollers 404 roll and smooth the paper towel. As the mounting plate 302 descends to a certain height, the pressure plate 501 comes into contact with the paper towel to emboss it.

[0028] A cylinder 301 is fixedly installed at the upper end of the top plate. The output shaft of the cylinder 301 is fixedly connected to the mounting plate 302. Multiple guide posts 303 are fixed at the upper end of the mounting plate 302. The guide posts 303 are slidably connected to the top plate. The cylinder 301 drives the mounting plate 302 to descend, so that the mounting plate 302 drives the guide posts 303 to slide and guide the top plate, ensuring that the force is evenly distributed at each position of the mounting plate 302.

[0029] A switch damper 502 is fixed on the mounting plate 302. A connecting rod 503 is rotatably connected to the lower end of the switch damper 502. The movable end of the connecting rod 503 is rotatably connected to the connecting arm 402. When the mounting plate 302 drives the pressure plate 501 to rise, the switch damper 502 drives the connecting arm 402 to rotate slowly through the connecting rod 503. This causes the connecting arms 402 on both sides to drive the rollers 404 to rotate slowly to below the pressure plate 501. This process is similar to the application of a door switch damper to prevent the two rollers 404 from rubbing the surface of the paper towel and causing wrinkles when the pressure plate 501 rises.

[0030] The conveying mechanism includes a groove 201, which is located on the upper end of the workbench 101. Multiple rollers and a conveyor belt 202 are provided in the groove 201. A conveyor motor 203 is fixedly installed at the front end of the workbench 101.

[0031] Multiple rollers are rotatably connected in the groove 201, and the conveyor belt 202 is connected to the multiple rollers. The output shaft of the conveyor motor 203 is fixedly connected to one side of the roller, and the conveyor motor 203 drives the roller to rotate, thereby driving the conveyor belt 202 to move.

[0032] Two fixing blocks 601 are fixed on one side of the workbench 101. The two fixing blocks 601 are symmetrical about the groove 201. A lead screw 602 is rotatably connected inside the fixing blocks 601.

[0033] A lifting block 701 is threaded onto the lead screw 602. A pressure roller 702 is rotatably connected between the front and rear symmetrical lifting blocks 701. The rotation of the lead screw 602 drives the lifting blocks 701 to descend, so that the lifting blocks 701 drive the pressure roller 702 to squeeze the surface of the paper towel for initial smoothing.

[0034] Working principle: During use, paper towels are placed on the conveyor belt 202 from the side of the worktable 101 away from the support plate 102. The conveyor motor 203 drives the roller shaft to rotate, causing the conveyor belt 202 to move. The lead screw 602 rotates, driving the lifting block 701 to descend. This causes the lifting block 701 to drive the pressure roller 702 to initially smooth the surface of the paper towels. The paper towels are then conveyed to the area below the mounting plate 302 via the conveyor belt 202. The heating tube 405 heats the roller 404 to a suitable temperature. Then, the cylinder 301 drives the mounting plate 302 to descend, causing the mounting plate 302 to slide against the guide column 303 against the top plate for guidance, ensuring even force distribution across all positions of the mounting plate 302. Mounting plate 302 drives pressure plate 501 to press down, causing symmetrical rollers 404 to roll against the surface of the paper towel. At the same time, connecting arm 402 rotates, causing gears 401 on both sides to mesh with each other. The heated rollers 404 then roll and smooth the paper towel. As mounting plate 302 descends to a certain height, pressure plate 501 comes into contact with the paper towel to emboss it. When mounting plate 302 drives pressure plate 501 to rise, switching damper 502 drives connecting arm 402 to rotate slowly through connecting rod 503. This causes the connecting arms 402 on both sides to drive rollers 404 to rotate slowly below pressure plate 501, preventing the two rollers 404 from rubbing the surface of the paper towel and causing wrinkles when pressure plate 501 rises.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
