Description

Technical Field

[0001] The utility model relates to the technical field of paper tissue production, in particular to a paper tissue stacking limiting device. Background Art

[0002] Tissue paper is also called box tissue, paper tissue, boxed facial tissue, tissue paper and tissue paper, etc. It has different names in different provinces and cities. It is an invention that combines practicality and beauty. In order not to waste expensive toilet paper, people divide it into square or rectangular shapes, stack them on each other, and then put them in a paper box with a small opening. Each time a piece of paper can be pulled out from the small opening, another piece of paper will be brought out, hence the name tissue paper.

[0003] After the folding process is completed, the existing paper is transferred to a conveyor belt for direct cutting. During the transfer process, the paper may be placed crookedly on the conveyor belt or the top may be tilted due to too many layers and large thickness. This may easily lead to an uneven cutting surface or an unsquare shape of the paper cut, or the top of the paper may be overturned due to force during cutting. At the same time, the paper is fluffy in the height direction. Direct cutting will affect the consistency of the overall size of the cut paper in the upper and lower directions, thereby affecting the cutting quality of the paper. In this regard, a Chinese patent with a publication number of CN214140100U discloses a conveyor belt for paper cutting, including a transfer conveyor platform, a limit conveyor slot and a cutting conveyor platform arranged in sequence. Conveyor belts are installed on the transfer conveyor platform and the cutting conveyor platform. The conveying direction of the conveyor belt is from the direction of the transfer conveyor platform to the direction of the cutting conveyor platform. A limit plate is arranged above one end of the limit conveyor slot close to the cutting conveyor platform, and the spacing between the limit plate and the limit conveyor slot is adjustable. An extrusion plate connected to the limit plate is arranged above the cutting conveyor platform, and the spacing between the extrusion plate and the cutting conveyor platform gradually decreases.

[0004] This patent uses an adjustable limit plate to limit paper of different thicknesses to prevent tilting, but the position of the limit transmission slot is fixed and cannot be adjusted. At the same time, the limit plate and the paper are in sliding contact. After long-term use, dust and paper scraps will adhere to the surface of the limit plate, which will increase the friction force on the surface of the limit plate. When the limit plate contacts the paper, the topmost paper will be offset, wrinkled, or damaged. For this reason, we propose a paper stacking limit device to solve the above problem.

When it comes to paper of different thicknesses, the adjustment component 9 is operated to change the angle between the clamping belt 10 and the transmission belt 5, which is more suitable for paper of different thicknesses.

[0021] Example 2

[0022] Reference Figure 1-2 , which is the second embodiment of the utility model, is based on the previous embodiment. Specifically, a plurality of guide rollers 11 are rotatably installed at the bottom of one side between the adjustment frames 8. The guide rollers 11 are evenly arranged and are evenly connected to the clamping belt 10. The guide rollers 11 tension the clamping belt 10. At the same time, the evenly arranged guide rollers 11 increase the contact area between the guide rollers 11 and the paper after contacting the paper, thereby improving the clamping effect.

[0023] Specifically, the bidirectional screw 4 is rotatably arranged inside the conveyor belt 5 , so that when the conveyor belt 5 is working, the normal rotation of the bidirectional screw 4 is not hindered.

[0025] When dealing with paper sheets of different thicknesses, operate the adjustment component 9 and rotate the threaded ring 94. The threaded ring 94 drives the threaded rod 95 to extend from or retract into the support tube 93 through the threaded structure, thereby changing the angle between the clamping belt 10 and the transmission belt 5, making it more suitable for paper sheets of different thicknesses.

[0026] Specifically, one end of a transmission cylinder 61 is connected to a servo motor through a transmission belt. The servo motor is fixedly mounted on the frame 1. When the servo motor works, the transmission cylinder 61 is driven to rotate, and the transmission cylinder 61 drives the transmission belt 5 to transmit the paper.

[0027] Example 3

[0028] Reference Figure 1-2 , which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, according to the size of the paper, the hand wheel 3 is rotated, and the hand wheel 3 drives the fixed bidirectional screw 4 to rotate. The bidirectional screw 4 drives the baffles 2 on both sides to move closer or farther away through the threaded structure, and then can be adjusted in time according to the size of the paper. The baffle 2 limits the paper to prevent the paper from tilting or offsetting. The servo motor works, and the transmission drives the transmission cylinder 61 to rotate. The transmission cylinder 61 drives the transmission belt 5 to transmit the paper. During the transmission process of the paper, it contacts the surface of the transmission belt 5, and then the friction of the contact surface drives the transmission belt 5 to rotate, thereby ensuring the compression effect, while preventing the transmission belt 5 from causing offset or wrinkles and damage to the paper, ensuring the flatness of the paper transmission process. When it is for paper of different thicknesses, the adjustment component 9 is operated to rotate the threaded ring 94. The threaded ring 94 drives the threaded rod 95 to extend from the support tube 93 or retract into the support tube 93 through the threaded structure, thereby changing the angle between the compression belt 10 and the transmission belt 5, which is more suitable for paper of different thicknesses.
