Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and in particular to a paper pressing mechanism for a tissue paper dispenser. Background Technology

[0002] A paper slitting machine, also known as a paper cutting machine, works by cutting a roll or sheet of raw material into fixed lengths. A paper pressing mechanism is an essential component of this machine.

[0003] Currently, most existing paper pressing mechanisms use rubber rollers. Over time, these rollers accumulate 0.5-1mm thick tissue fibers, forming a fiber layer on their surface. When the rollers rotate, this fiber layer drags the edges of the tissue, causing wavy wrinkles 2-3mm wide. This is especially problematic when slitting high-end embossed tissues, as the wrinkles disrupt the integrity of the embossed pattern, leading to a lower product appearance pass rate. Therefore, to better clean the fibers from the roller surface, promote technological advancement in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing paper pressing mechanisms in paper slitting machines. Utility Model Content

[0004] The purpose of this invention is to solve the problem of fiber layer appearing on the surface of existing pressure rollers, which affects the finished product qualification rate, and to propose a paper pressing mechanism for a tissue paper separator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A paper pressing mechanism for a tissue dispenser includes two mounting plates. A rotating rod is rotatably mounted between the two mounting plates via an interlocking bearing. A rubber wheel is sleeved on the outer wall of the rotating rod. A mounting shell is fitted between the two ends of the rotating rod, covering the outside of the rubber wheel. Multiple support rods are fixedly connected to one side of the outer wall of the mounting shell. A connecting plate is slidably sleeved between the multiple support rods. A scraper is fixedly connected to one side of the connecting plate, and the scraper can contact the rubber wheel. A threaded rod is rotatably connected to one side of the outer wall of the mounting shell. The connecting plate and the threaded rod are threadedly connected. A mounting box is inserted into the top of the mounting shell. A dust suction port is provided at the bottom of the mounting box. A dust suction pipe is sealed and inserted into the top of the mounting box.

[0006] Furthermore, both ends of the top outer wall of the mounting housing are slidably connected with pins, which can be inserted into the mounting plate.

[0007] Furthermore, two slide rails are fixedly connected between the two mounting plates, and multiple mounting brackets are slidably connected between the two slide rails. A first gear and a second gear are rotatably mounted on one side of the mounting bracket via an interlocking bearing, and the first gear meshes with the second gear.

[0008] Furthermore, a splined shaft is rotatably mounted between the two mounting plates via an interlocking bearing, and the first gear is keyed to the splined shaft.

[0009] Furthermore, a blade is fixedly connected to one end of the second gear.

[0010] Furthermore, a support plate is fixedly connected to the bottom of the mounting bracket, and the support plate is located below the blade.

[0011] Furthermore, the two rubber wheels are arranged vertically opposite each other.

[0012] The beneficial effects of this utility model are as follows: 1. The fiber layer adhering to the rubber wheel is scraped off by the rotating rubber wheel and scraping by the scraper, thereby avoiding wrinkles on the paper towel during the conveying process and ensuring the integrity of the embossed pattern.

[0013] 2. The scraped fibers are sucked into the mounting box through the vacuum nozzle by the vacuum cleaner, and then collected in the vacuum cleaner through the vacuum tube, so as to facilitate timely collection of fibers and avoid affecting the delivery of paper towels.

[0014] 3. By turning the threaded rod, the connecting plate moves along the support rod, thereby driving the scraper to move and contact the rubber wheel, so as to scrape off fiber layers of different thicknesses and improve the applicability of the device. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1-5 A paper pressing mechanism for a tissue paper dispenser includes two mounting plates 1. A rotating rod 9 is rotatably mounted between the two mounting plates 1 via an interlocking bearing. A rubber wheel 10 is sleeved on the outer wall of the rotating rod 9. The two rubber wheels 10 are driven to rotate relative to each other by two motors, thereby conveying tissue paper. A mounting shell 11 is fitted between the two ends of the rotating rod 9 with a gap. The mounting shell 11 covers the outside of the rubber wheel 10. Multiple support rods 16 are welded to one side of the outer wall of the mounting shell 11. A connecting plate 13 is slidably fitted between the multiple support rods 16. A scraper 14 is fixed to one side of the connecting plate 13 by bolts. The scraper 14 can contact the rubber wheel 10. When the rubber wheel 10 rotates, it scrapes against the scraper 14, thereby scraping off the fiber layer adhering to the rubber wheel 10. A threaded rod 15 is rotatably connected to one side of the outer wall of the mounting shell 11. The connecting plate 13 is threadedly connected to the threaded rod 15. Tightening the threaded rod 15 causes the connecting plate 13 to move along the support rod 16, thereby driving the scraper 14 to move and contact the rubber wheel 10, so as to scrape off fiber layers of different thicknesses. The top of the mounting housing 11 is connected to the mounting box 17, the bottom of the mounting box 17 is provided with a suction port, and the top of the mounting box 17 is sealed with a suction pipe 18. The scraped fibers are sucked into the mounting box 17 through the suction port by the vacuum cleaner, and then collected in the vacuum cleaner through the suction pipe 18.

[0019] Both ends of the top outer wall of the mounting shell 11 are slidably connected with pins 12. The pins 12 can be inserted into the mounting plate 1. Pushing the pins 12 into the mounting plate 1 will install the mounting shell 11 between the two mounting plates 1.

[0020] Two mounting plates 1 are fixed together by bolts, and two slide rails 2 are slidably connected between the two slide rails 2. The bottom of the mounting bracket 3 is provided with a slider that matches the slide rail 2. The distance between the two mounting brackets 3 is adjusted by pushing the mounting bracket 3 so that the slider can slide on the slide rail 2 to accommodate the cutting of paper towels of different widths. After adjustment, the mounting bracket 3 is fixed by tightening the bolts on the side of the mounting bracket 3 that correspond to the reserved screw holes on the slide rail 2. A first gear 4 and a second gear 5 are rotatably mounted on one side of the mounting bracket 3 via an interlocking bearing. The first gear 4 meshes with the second gear 5. A splined shaft 6 is rotatably mounted between the two mounting plates 1 via an interlocking bearing. The first gear 4 is keyed to the splined shaft 6. A blade 7 is fixed to one end of the second gear 5 by bolts. The splined shaft 6 is driven to rotate by a motor, which in turn drives the first gear 4 to rotate. Under the action of the meshing of the first gear 4 and the second gear 5, the blade 7 is driven to rotate. The blade 7 cuts the paper towels as they are fed.

[0021] The two motors driving the rubber wheels 10 and the motor driving the splined shaft 6 are electrically connected to an external controller of model DATA-7311. The controller has a preset control program. When the paper feeder is started, the controller controls each motor to start sequentially according to the preset program. By adjusting the parameters of the controller, the speed and forward / reverse rotation of the motors can be controlled. When the paper towel feeding is completed or a malfunction occurs, the controller can promptly stop the motors.

[0022] The bottom of the mounting bracket 3 is fixed with a support plate 8 by bolts. The support plate 8 is located below the blade 7, thereby providing support for the cutting of the paper towel.

[0023] Two rubber wheels 10 are positioned vertically opposite each other.

[0024] The working principle of this embodiment is as follows: The mounting shell 11 is placed on both ends of the rotating rod 9 and covers the outside of the rubber wheel 10. Then, the pin 12 is pushed to be inserted into the mounting plate 1, thereby installing the mounting shell 11 between the two mounting plates 1. Then, the threaded rod 15 is turned to make the connecting plate 13 move along the support rod 16, thereby driving the scraper 14 to move and contact the rubber wheel 10. Then, the locking nut at one end of the threaded rod 15 is tightened to fix it, thereby fixing the scraper 14. In use, the paper towel passes between the two rubber wheels 10. Then, the two rubber wheels 10 are driven to rotate relative to each other by two motors, thereby conveying the paper towel to the carrier plate 8. Next, the spline shaft 6 is driven to rotate by the motor, thereby driving the first gear 4 to rotate. Then, the blade 7 is driven to rotate under the action of the first gear 4 and the second gear 5 meshing. The paper towel is cut by the blade 7 while being conveyed. During the cutting process, the rubber wheel 10 rotates and scrapes against the scraper 14, thereby scraping off the fiber layer adhering to the rubber wheel 10. At the same time, the suction pipe 18 is connected to an external vacuum cleaner, which sucks the scraped fibers into the mounting box 17 through the suction port, and then into the vacuum cleaner for collection through the suction pipe 18. This avoids wrinkling the paper towel during transportation and ensures the integrity of the embossed pattern.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
