A negative pressure device creates negative pressure inside the first air chamber, and the micropores near the folding and cutting spur gears generate suction for the paper drawer, causing the paper to adhere tightly to the surface of the folding main gear. During use, the second air guide ring is only connected to the blower. The internal cavity is located near the main folding gear. The blower blows air onto the surface of the folding gear, further adhering the paper to the surface of the main folding gear and preventing the paper from breaking during the squeezing process. The second air chamber is located directly above the paper outlet guide plate. After the paper is cut by the paper cutting gear, it moves to the top of the paper outlet guide plate. The blower increases the air pressure inside the second air chamber and blows air through the micro-holes directly above the paper outlet guide plate to separate the paper from the surface of the main folding gear, causing it to fall into the interior of the paper outlet guide plate.

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The spur gear paper folding and cutting mechanism involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Reference Figures 1 to 6 This utility model provides a spur gear type paper folding and cutting mechanism, including a side plate 1. Two embossing rollers 8 are movably sleeved on the inner side wall of the side plate 1. Paper drawers 10 are drivenly connected to the side of the embossing rollers 8. A folding spur gear 9 is movably sleeved on the inner side wall of the side plate 1, and a folding main gear 2 is movably sleeved on the inner side wall of the side plate 1. The structure of the folding main gear 2 is the same as that of the folding spur gear 9. The side of the folding spur gear 9 meshes with the side of the folding main gear 2 to guide the paper drawers. 10 is used for creasing. A paper-cutting spur gear 3 is movably sleeved on the inner side wall of the side plate 1. The side of the paper-cutting spur gear 3 meshes with the side of the paper-cutting spur gear 2 to cut the tissue 10. A paper outlet guide plate 5 is fixedly connected to the inner side wall of the side plate 1 at the position corresponding to the folding main gear 2. A receiving hopper 501 is fixedly connected to the top of the paper outlet guide plate 5. The folding spur gear 9 and the folding main gear 2 achieve synchronous transmission through the meshing of two transmission gears. The paper-cutting spur gear 3 and the folding main gear 9... Wheel 2 achieves synchronous transmission through the meshing of two transmission gears. The two embossing rollers 8 on both sides also achieve synchronous transmission through the meshing of two transmission gears. The folding spur gear 9 and the embossing roller 8 on the left side achieve synchronous transmission through the cooperation of a chain and sprocket. During the production of tissue paper 10, it passes between the two embossing rollers 8, and the embossing rollers 8 process the tissue paper 10 to create patterns. Then it is conveyed between the folding spur gear 9 and the folding main gear 2. The folding spur gear 9 and the folding main gear 2 mesh with each other to press creases into the tissue paper 10, and the tissue paper 10 adheres to the surface of the folding main gear 2. As the folding main gear 2 rotates, the cutting spur gear 3 meshes with the folding main gear 2, and the cutting spur gear 3 cuts the tissue paper 10. The tissue paper 10 moves above the paper outlet guide plate 5 with the folding main gear 2 and falls into the paper outlet guide plate 5 for the next cutting and packaging process, realizing the synchronization of tissue paper folding and cutting, and improving production efficiency.

[0018] The origami main gear 2 has a tooth tip 201 on the top of its teeth and a first mounting groove 202 at the bottom of its tooth groove. A silicone strip 203 is fixedly connected to the side of the first mounting groove 202. When the origami main gear 2 and the origami spur gear 9 mesh with each other, the tooth tip 201 presses the paper puller 10 into the silicone strip 203, and the silicone strip 203 deforms and exerts sufficient pressure on the paper puller 10 to achieve folding of the paper puller 10.

[0019] The silicone strip 203 has a groove on its side and an X-shaped cross-section. The tip of the toothed blade 201 is specially designed as a short blade, and the connection between the toothed blade 201 and the gear surface is a smooth transition. The cross-section of the toothed blade 201 is nipple-shaped, ensuring that the toothed blade 201 can be smoothly inserted into the groove on the side of the silicone strip 203, and avoiding gaps at the contact point between the silicone strip 203 and the toothed blade 201.

[0020] The paper-cutting spur gear 3 has a second mounting groove 302 on the top of its teeth, and the second mounting grooves 302 are spaced apart on the top of the teeth of the paper-cutting spur gear 3. A paper cutter 301 is fixedly connected to the side of the second mounting groove 302. The number of teeth of the paper-cutting spur gear 3 is the same as the number of teeth of the folding main gear 2. The top of the paper cutter 301 has a serrated structure. The side of the paper cutter 301 meshes with the side of the silicone strip 203. The paper cutter 301 presses the tissue 10 into the silicone strip 203 and presses out creases along the folding spur gear 9 and the folding main gear 2, making intermittent cuts so that the surface of the tissue 10 forms a cutting line.

[0021] The side plate 1 has an idler wheel 7 movably sleeved on its inner side wall. The side of the idler wheel 7 is movably connected to the side of the tissue box 10. The center line connecting the tissue box 10, the folding spur gear 9, and the folding main gear 2 is perpendicular to each other. The idler wheel 7 guides the tissue box 10, allowing it to pass through the bottom of the idler wheel 7 and be fed between the folding spur gear 9 and the folding main gear 2. It also ensures that the tissue box 10 is tangent to the outer diameter of the folding spur gear 9 and the folding main gear 2, thus preventing damage to the tissue box 10.

[0022] The origami main gear 2 has a ventilation hole 205 on its side, and the tooth surface of the origami main gear 2 has a micro-hole 204 at the position corresponding to the ventilation hole 205. The side of the origami main gear 2 is movably sleeved with a first air guide ring 4 at the position corresponding to the ventilation hole 205. The side of the first air guide ring 4 is fixedly connected to the inner wall of the side of the side plate 1. The side of the origami spur gear 9 is movably sleeved with a second air guide ring 6. The structure of the second air guide ring 6 is the same as the structure of the first air guide ring 4.

[0023] The first air guide ring 4 has a first air chamber 401 on its inner side wall corresponding to the position of the folding spur gear 9. A first connecting pipe 402 is fixedly connected to the side of the first air chamber 401, and a negative pressure device is fixedly connected to the side of the first connecting pipe 402. A second air chamber 403 is formed on the inner side wall of the first air guide ring 4 corresponding to the position of the paper outlet guide plate 5. A second connecting pipe 404 is fixedly connected to the side of the second air chamber 403, and a blower is fixedly connected to the side of the second connecting pipe 404. The side of the second air guide ring 6 is fixedly connected to the output end of the blower through an air guide pipe. The first air chamber 401 is located near the folding spur gear 9 and the paper cutting spur gear 3. Ventilation holes 205 are evenly distributed at both ends of the folding main gear 2. As the folding main gear 2 rotates, the ventilation holes 205 located near the folding spur gear 9 and the paper cutting spur gear 3 communicate with the first air chamber 401. A negative pressure device creates a negative pressure inside the first air chamber 401. The micro-holes 204 near the folding spur gear 9 and the cutting spur gear 3 generate suction on the paper puller 10, causing the paper puller 10 to adhere tightly to the surface of the folding main gear 2. During use, the second air guide ring 6 is only connected to the blower, and the cavity inside the second air guide ring 6 is located near the folding main gear 2. The blower blows air onto the paper puller 10 from the surface of the folding spur gear 9, further adhering the paper puller 10 to the surface of the folding main gear 2. The second air chamber 403 is located directly above the paper outlet guide plate 5. After the paper puller 10, cut by the cutting spur gear 3, moves to the top of the paper outlet guide plate 5, the blower increases the air pressure inside the second air chamber 403. Air is blown from the micro-holes 204 directly above the paper outlet guide plate 5, separating the paper puller 10 from the surface of the folding main gear 2 and causing it to fall into the interior of the paper outlet guide plate 5.

[0024] The working principle of this utility model is as follows: The tissue paper 10 passes between two embossing rollers 8, and the embossing rollers 8 process the tissue paper 10 to create patterns. After being guided by the idler wheel 7, it is conveyed between the folding spur gear 9 and the folding main gear 2. As the folding main gear 2 rotates, the vent 205 located near the folding spur gear 9 and the paper cutting spur gear 3 is connected to the first air chamber 401. A negative pressure device creates a negative pressure inside the first air chamber 401, and the micropores 204 near the folding spur gear 9 and the paper cutting spur gear 3 generate suction on the tissue paper 10, thereby making the tissue paper 10 stick tightly to the surface of the folding main gear 2. During use, the second air guide ring 6 is only connected to the blower, and the internal cavity of the second air guide ring 6 is located near the folding main gear 2. The blower blows air onto the tissue paper 10 from the surface of the folding spur gear 9, further adhering the tissue paper 10 to the surface of the folding main gear 2. As the folding spur gear 9 and the folding main gear 2 rotate synchronously, the tissue paper 10 is conveyed between the folding spur gear 9 and the folding main gear 2. The paper main gears 2 mesh with each other, and the toothed blade 201 presses the paper towel 10 into the silicone strip 203. The silicone strip 203 deforms and exerts sufficient pressure on the paper towel 10, thus folding the paper towel 10. As the folding main gear 2 rotates, the paper cutting spur gear 3 and the folding main gear 2 mesh with each other. The paper cutter 301 presses the paper towel 10 into the silicone strip 203 and creates creases along the folding spur gear 9 and the folding main gear 2. The paper is cut intermittently to form a cutting line on the surface of the tissue box 10. As the folding main gear 2 moves above the paper outlet guide plate 5, the blower increases the air pressure inside the second air chamber 403. Air is blown from the micro-hole 204 directly above the paper outlet guide plate 5 to separate the tissue box 10 from the surface of the folding main gear 2 and make it fall into the paper outlet guide plate 5. The tissue box 10 then falls into the paper outlet guide plate 5 for the next cutting and packaging process, realizing the synchronization of tissue box folding and cutting, and improving production efficiency.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
