Description

Technical Field

[0001] This invention relates to the field of tissue paper folding equipment, and in particular to a fully automatic folding and dispensing facial tissue machine. Background Technology

[0002] As people's living standards improve, the demand for different types of household paper products is becoming increasingly segmented. Common types include toilet paper, kitchen paper towels, and facial tissues, each with different materials and intended for different uses. Toilet paper and kitchen paper towels are both produced in rolls. Traditional facial tissue production equipment folds the tissues and pushes them to the feeding port on the front of the machine, where workers then dispense the tissues in fixed quantities. Manual dispensing can lead to inaccurate dispensing and affects production efficiency.

[0003] Existing equipment also has problems in the tissue paper separation process. The optimal separation effect is that half of the bottom paper falls off after separation. To achieve this effect, the forks need to be lengthened and inserted from one side. Current technology requires separating folding and cutting, which requires six sets of rollers. This not only makes the equipment bulky but also very expensive to manufacture and complex to operate. Current automatic tissue paper separating equipment generally uses a two-set fork insertion process. This separation method has drawbacks. Because the separated bottom paper has to pass through the gap between the two sets of forks, at least three-quarters of the bottom paper falls off. The excessive and unstable length of the bottom paper makes it difficult to handle, resulting in the bottom tissues being folded unevenly, leading to poor packaging results. Using a single-side insertion method, because the forks are too long, the drop between the upper surface of the fork and the folding roller surface is large after insertion, causing uneven folding, unstable separation, and loose separated paper. Summary of the Invention

[0004] This invention aims to address at least the technical problems existing in the prior art, namely: "traditional tissue paper production equipment suffers from inaccurate counting and low production efficiency due to manual tissue separation"; "the equipment is complex to operate, has high manufacturing costs, and is bulky"; and "the bottom paper falls too far and the fall length is unstable after tissue separation, resulting in uneven folding of the tissues at the bottom, leading to poor packaging effect, and the separated tissues are loose due to uneven folding and unstable separation." To address these issues, this invention proposes a fully automatic folding and dispensing tissue paper machine that can automatically separate and transport folded tissues, simplifying operation and improving production efficiency; it also keeps the bottom of the tissues flat for easy packaging, ensuring neat and non-loose tissues during the separation process.

[0015] The fully automatic folding and dispensing facial tissue dispenser according to some embodiments of the present invention has at least the following beneficial effects:

[0016] 1. The servo control component is used to control the orderly action of each mechanism. The servo control component realizes automatic paper separation of the paper drawer, which makes the number of paper drawers more accurate, improves the paper folding accuracy, and improves the folding efficiency. The operation is simple. The device can run automatically by simply calling the preset folding parameters of the servo control component.

[0017] 2. When the paper is separated using the swing arm lifting separation mechanism, the upper plane of the paper separating fork rises simultaneously as it swings and inserts, reducing the drop difference between the paper separating fork and the folding mechanism, making the paper separation more stable, and avoiding loose and uneven folding of the paper, which would result in poor folding effect.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, top, bottom, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0040] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0041] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0042] The following is for reference. Figures 1-11 A fully automatic folding and dispensing facial towel machine according to an embodiment of the present invention is described.

[0043] like Figures 1-11As shown, the fully automatic folding and dispensing facial tissue machine includes a frame 100. A paper feeding mechanism 100 is arranged above the frame 100, and a folding mechanism 120 is arranged below the paper feeding mechanism 100. Since the paper feeding mechanism 100 and the folding mechanism are mechanical structures well known to those skilled in the art, they will not be described in detail in this invention. Both the paper feeding mechanism 100 and the folding mechanism 120 are arranged above the frame 100. After the facial tissues come out of the folding mechanism 120, they are folded together. A paper separating mechanism is arranged below the folding mechanism 120, which is located on the frame 100. A conveyor belt mechanism 500 is arranged below the paper separating mechanism. After the facial tissues come out of the folding mechanism 120, they fall into the paper holding mechanism. The folded facial tissues are transported to the conveyor belt mechanism 500 by the paper separating mechanism. The conveyor belt mechanism 500 transports the facial tissues from inside the equipment to outside the equipment, and then conveys them to the next process for cutting, packaging, and other steps.

[0044] The conveyor belt mechanism 500 is horizontally positioned within the frame 100, rotating along both sides of the frame 100. When the folded finished tissues are transported to the conveyor belt mechanism 500, it carries the tissues out from the side wall of the frame 100. Traditional folding and separating paper equipment often uses a front-loading method, where the folded tissues are pushed to the front for handling by workers. This front-loading method requires more space in front of the equipment, and because the tissues are transported to the front, an additional mechanism is needed to push them from the folding mechanism 120 to the front. This additional mechanism makes the folding and separating equipment larger and more complex internally, resulting in excessive space usage and poor space utilization in confined spaces. In contrast, the conveyor belt mechanism 500, which outputs paper from both sides, transports the folded tissues directly from the sides of the equipment, reducing the area occupied by the folding and separating equipment, simplifying its mechanism, and lowering manufacturing costs.

[0045] The paper separating mechanism includes a swing arm lifting and separating mechanism 200 and a supporting mechanism 400, which are symmetrically distributed above the conveyor belt mechanism 500. The swing arm lifting and separating mechanism 200 is driven by a first drive mechanism, which drives it to reciprocate up and down between the folding mechanism 120 and the conveyor belt mechanism 500. The supporting mechanism 400 is driven by a second drive mechanism, which also drives it to reciprocate up and down between the folding mechanism 120 and the conveyor belt mechanism 500. The swing arm lifting and separating mechanism 200 and the supporting mechanism 400 move alternately, achieving uninterrupted transport and improving the production efficiency of the equipment.

[0046] An air duct mechanism 130 is also provided on one side of the support mechanism 400. The air duct mechanism 130 is fixedly connected to the frame 100. The air duct mechanism 130 is used to blow air towards one side of the support mechanism 400 to keep the bottom of the paper drawer flat at the paper holding mechanism. In this invention, the air duct mechanism 130 is an air duct fixedly connected to the frame 100, specifically located behind the support mechanism 400. The air duct is arranged horizontally and can completely cover the bottom area of ​​the paper drawer, thereby blowing air over a large area of ​​the bottom of the paper drawer to make the paper drawer close to the bottom.

[0047] In order to accurately control the above mechanisms, a servo control component (not shown in the attached drawings) is also provided in the equipment. The servo control component is electrically connected to the first drive mechanism, the second drive mechanism, the swing arm lifting and separating mechanism 200 and the supporting mechanism 400 respectively. The servo control component can accurately control the swing arm lifting and separating mechanism 200 and the supporting mechanism 400, so that the two mechanisms can work together precisely, improve the accuracy of folding and drawing, and improve production efficiency.

[0048] Specifically, in the initial state, the swing arm lifting and separating mechanism 200 is located at the top, close to the discharge port of the folding mechanism 120, and the supporting mechanism 400 is located below the swing arm lifting and separating mechanism 200. The tissues from the folding mechanism 120 are continuously stacked on the swing arm lifting and separating mechanism 200. The swing arm lifting and separating mechanism 200 gradually moves downward as the tissues are stacked. When the swing arm lifting and separating mechanism 200 and the supporting mechanism 400 are at the same horizontal position, the swing arm lifting and separating mechanism 200 is pulled out, and the tissues are placed on the supporting mechanism 400. The supporting mechanism 400 then gradually moves downward to continue stacking, while the swing arm lifting and separating mechanism 200 swings backward and returns to the top. When the tissues on the supporting mechanism 400 are stacked... After a specified number of tissue boxes are stacked, the swing arm lifting and separating mechanism 200 quickly swings and inserts, while the supporting mechanism 400 quickly moves downward. The swing arm lifting and separating mechanism 200 inserts above the supporting mechanism 400. After the supporting mechanism 400 moves to the conveyor belt mechanism 500, it places the tissue box onto the conveyor belt mechanism 500. The conveyor belt mechanism 500 transports the tissue box to the outside, and the supporting mechanism 400 quickly rises back. Meanwhile, the air duct mechanism 130 activates the airflow, blowing the tissue box at the bottom of the swing arm lifting and separating mechanism 200 to make the tissue box stick tightly to the bottom. The supporting mechanism 400 rises back to support the bottom of the tissue box, keeping the bottom of the tissue box flat. The swing arm lifting and separating mechanism 200 pulls out after the supporting mechanism 400 supports the tissue box. The swing arm lifting and separating mechanism 200 and the supporting mechanism 400 repeat the above steps to achieve continuous transportation of tissue boxes and improve production efficiency.

[0049] The embodiments of the present invention will now be described in detail in three parts: the swing arm lifting and separating mechanism 200, the supporting mechanism 400, and the conveyor belt mechanism 500.

[0050] The first part mainly describes embodiments of the swing arm lifting and separating mechanism 200. In some embodiments of the present invention, such as... Figure 1 , Figure 5 and Figure 6 As shown, the swing arm lifting and separating mechanism 200 includes a connecting plate 210. Specifically, the connecting plate 210 is a component that supports other parts of the swing arm lifting and separating mechanism 200 and is elongated. Guide plates are provided with guide blocks 220 on both sides of the connecting plate 210. The first driving mechanism is connected to the guide blocks 220 on both sides of the connecting plate 210. By driving the guide blocks 220 to move up and down, the swing arm lifting and separating mechanism 200 is simultaneously driven to slide up and down.

[0051] To enable the swing arm lifting and separating mechanism 200 to move more smoothly during its up-and-down sliding, a first buffer cylinder 233 is provided between the first drive mechanism and the guide block 220. In this embodiment, there are two sets of first buffer cylinders 233, with one set on each side. The cylinder body of the first buffer cylinder 233 is fixedly connected to the frame 100, while its push rod is connected to the guide block 220 and slides synchronously. When the first drive mechanism drives the swing arm paper separating mechanism 200 to move up and down, the first buffer cylinder 233 can make the descent of the swing arm paper separating mechanism 200 smoother, provide a certain load-bearing capacity to support the swing arm paper separating mechanism 200, and reduce the load on the first drive mechanism. The first drive mechanism includes a first servo motor 231, which is fixedly connected to the frame 100. A first transmission shaft 232 is rotatably connected to the frame 100. The first servo motor 231 and the first transmission shaft 232 are connected in a transmission manner. The two ends of the first transmission shaft 232 are respectively connected in a transmission manner to the guide blocks 220 on both sides of the connecting plate 210. Specifically, the first transmission shaft 232 and the guide blocks 220 are connected by a belt. The belt is connected to a tension pulley on the frame 100. The belt is connected between the first transmission shaft 232 and the tension pulley. The guide blocks 220 clamp the belt. When the first servo motor 231 drives the first transmission shaft 232 to rotate, the belts on both sides rotate synchronously, driving the guide blocks 220 on both sides to rotate synchronously. The connecting plate 210 and the guide blocks 220 move simultaneously. The swing arm paper separating mechanism 200 is set on the connecting plate 210 and moves up and down under the drive of the first servo motor 231.

[0052] It should be understood that using a first driving mechanism and a belt to drive the swing arm lifting and separating mechanism 200 to move up and down is not the only implementation method. In some other embodiments, a linear guide rail can also be used to drive the swing arm paper separating mechanism 200 to move up and down according to actual production needs. The guide block 220 is fixedly connected to the slider of the linear guide rail, and the linear guide rail is electrically connected to the servo control component. The servo control component controls the linear guide rails on both sides to drive the connecting plate 210 to move up and down, thereby controlling the swing arm lifting and separating mechanism 200 to move up and down. The present invention does not describe in detail the structure for controlling the movement of the swing arm lifting and separating mechanism 200. It should be understood that, without departing from the basic concept of the present invention, flexible changes in the structure for controlling the movement of the swing arm lifting and separating mechanism 200 should all be considered within the scope of protection defined by the present invention.

[0053] like Figures 7-10 As shown, the connecting plate 210 is slidably connected to the guide block 220. The connecting plate 210 can slide back and forth relative to the guide block 220. Specifically, in this embodiment, a first cylinder 221 is fixedly connected to the guide block 220. The cylinder body of the first cylinder 221 is fixedly connected to the side wall of the guide block 220, and the push rod of the first cylinder 221 is connected to the connecting plate 210. The first cylinder 221 pushes the connecting plate 210 to slide back and forth on the guide block 220 through the push rod. Guide rails are provided on both sides of the connecting plate 210, and guide blocks 220 are slidably connected to the guide rails. Since guide blocks 220 only slide in the vertical direction and not in the horizontal direction, when the first cylinder 221 pushes the push rod, the connecting plate 210 slides in the horizontal direction. In order to prevent the connecting plate 210 from exceeding the stroke during the process of the first cylinder 221 pulling back, first hydraulic buffers 211 are provided on both sides of the connecting plate 210. The buffer rod of the first hydraulic buffer 211 faces the guide block 220 to reduce the impact on the connecting plate 210 when it approaches the guide block 220, and can also play a certain limiting role to limit the distance of the connecting plate 210 sliding backward.

[0054] like Figure 9 and Figure 10As shown, a paper-splitting shaft 212 is rotatably connected to the connecting plate 210. Several paper-splitting forks 213 are evenly spaced on the paper-splitting shaft 212. The paper-splitting forks 213 are fixedly connected to the paper-splitting shaft 212. The two ends of the paper-splitting shaft 212 are respectively connected to the two sides of the connecting plate 210. The paper-splitting forks 213 move synchronously with the paper-splitting shaft 212, and the paper-splitting shaft 212 moves synchronously with the connecting plate 210. In this embodiment, the paper-splitting fork 213 is L-shaped, with the short side being the end that carries the paper, and the long side being fixedly connected to the paper-splitting shaft 212. In order for the paper-splitting shaft 212 to drive the paper-splitting fork 213 to rotate, a second servo motor 214 is fixedly installed on the connecting plate 210. Specifically, the second servo motor 214 is installed in the middle of the connecting plate 210. The second servo motor 214 is rotatably connected to the paper-splitting shaft 212 through an eccentric wheel and connecting rod lifting mechanism. The second servo motor 214 drives the paper-splitting shaft 212 and the paper-splitting fork 213 to swing through the eccentric wheel and connecting rod lifting mechanism, so that the paper-splitting fork 213 has enough space to be inserted into the paper. In order to make the paper separating shaft 212 and the paper separating fork 213 move upward, two second swing arms 380 are provided at both ends of the paper separating shaft 212 and are fixedly connected to the paper separating shaft 212. The second swing arms 380 and the second sliding bushing 216 are rotatably connected through the second connecting rod 360. Under the drive of the second swing arms 380, the paper separating shaft 212 and the paper separating fork 213 will move upward. To ensure that the paper separating shaft 212 remains level on both sides and that all the paper separating forks 213 on the paper separating shaft 212 move in unison during upward movement, a first sliding bushing 215 is connected to the middle of the paper separating shaft 212. The first sliding bushing 215 is fixedly connected to the connecting plate 210, allowing the paper separating shaft 212 to move up and down within the first sliding bushing 215, thereby changing the shaft height. Second sliding bushings 216 are connected to both ends of the paper separating shaft 212, which are fixedly connected to both sides of the connecting plate 210. The paper separating shaft 212 moves up and down within both the first sliding bushing 215 and the second sliding bushings 216. When the paper separating shaft 212 is lifted by the second swing arm 380, it moves up and down under the limiting action of the first sliding bushing 215 in the middle and the second sliding bushings 216 on both sides, ensuring that the paper separating shaft 212 remains level during the lifting process, thus ensuring that the folded paper on the paper separating forks 213 does not tilt.The two ends of the paper separating shaft 212 are rotatably connected to two swing arms 320 respectively. By providing first swing arms 320 in the middle and on both sides of the paper separating shaft 212, the paper separating shaft 212 rotates more smoothly and avoids tilting of the left and right sides of the paper separating shaft 212 during the lifting process. Specifically, the second swing arm 380 and the second sliding bushing 216 are connected by a second connecting rod 360. A second hydraulic damper 370 is fixedly connected to the second sliding bushing 216. The second hydraulic damper 370 is set close to the side of the second swing arm 380, and the push rod of the second hydraulic damper 370 is close to the side of the second swing arm 380. The second hydraulic damper 370 can provide a certain buffering effect during the lifting process of the second swing arm 380, so that the paper separating shaft 212 and the paper separating fork 213 remain stable during the insertion process.

[0055] like Figure 9 and 10 As shown, the eccentric wheel and linkage lifting mechanism includes an eccentric wheel 310, which is rotatably connected to the output shaft of the second servo motor 214. A paper-separating shaft 212 is fixedly connected to a first swing arm 320. The eccentric wheel 310 and the first swing arm 320 are connected via a first connecting rod 330. Second swing arms 380 are fixedly connected to both ends of the paper-separating shaft 212. The second swing arms 380 are connected to a second sliding bushing 216 via a second connecting rod 360. The second sliding bushing 216 is fixedly connected to both sides of the connecting plate 210. The second servo motor 214 drives the eccentric wheel 310, which in turn drives the first swing arm 320 to swing via the first connecting rod. The first swing arm 320 drives the paper-separating shaft 212 to rotate, and the rotation of the paper-separating shaft 212 drives the second swing arm 380 to swing. Under the influence of the first and second swing arms 320, the swing lifting function is achieved. Specifically, the paper-splitting shaft 212 swings rapidly and rises upward, causing the paper-splitting fork 213 to insert into the folded tissue paper, dividing the folded tissue paper into a preset number of tissues. To enable the servo control component to detect the current working status and rotation angle of the paper separating shaft 212, a turntable 340 is connected between the output shaft of the eccentric wheel 310 and the second servo motor 214. The turntable 340 rotates synchronously with the eccentric wheel 310. A notch 341 is provided on the periphery of the turntable 340. A photoelectric sensor 350 is provided on one side of the turntable 340. The photoelectric sensor 350 is used to detect the rotation angle of the turntable 340 and the eccentric wheel 310. Specifically, the photoelectric sensor 350 is fixedly installed at the connecting plate 210. When the eccentric wheel 310 and the turntable 340 rotate synchronously, whenever the notch 341 of the turntable 340 passes the photoelectric sensor 350, the photoelectric sensor 350 is connected, thereby feeding back the status of the paper separating shaft 212 to the servo control component. The servo control component can adjust the equipment according to the information fed back by the photoelectric sensor 350 to ensure the accuracy of each paper separating operation.

[0056] It should be understood that using an eccentric wheel and connecting rod lifting mechanism to swing and raise / lower the paper-splitting fork 213 is not the only implementation method. Replacing the second swing arm 380 and the second connecting rod 360 with a cam can also achieve the swing and raising / lowering of the paper-splitting fork 213. This invention does not elaborate on the structure for controlling the swing and raising / lowering of the paper-splitting fork 213. It should be understood that, without departing from the basic concept of this invention, any flexible changes to the swing and raising / lowering structure of the paper-splitting fork 213 should be considered within the scope of protection defined by this invention.

[0057] The second part mainly describes embodiments of the support mechanism 400. In some embodiments of the present invention, such as... Figure 1 , Figure 3 and 11 As shown, the supporting mechanism 400 includes a fixed plate 420, and sliding blocks 430 are slidably connected to both sides of the fixed plate 420. The second driving mechanism includes a third servo motor 411, which is fixedly connected to the frame 100. The third servo motor 411 is rotatably connected to the sliding block 430. The specific connection method and structure are the same as the connection method of the first servo motor 231 and the guide block 220 in the swing arm paper separating mechanism 200. It will not be described in detail here. Please refer to the connection method of the swing arm paper separating mechanism 200 described above. The third servo motor 411 is used to drive the slider to move up and down. The fixed plate 420 slides up and down synchronously with the sliding block 430. Several supporting forks 421 are fixedly installed on the fixed plate 420. The supporting forks 421 are evenly spaced on the fixed plate 420. The supporting forks 421 and the paper-splitting forks 213 are staggered. Specifically, the shape of the supporting forks 421 is the same as the shape of the paper-splitting forks 213. The supporting forks 421 and the paper-splitting forks 213 are symmetrically arranged, and the supporting forks 421 and the paper-splitting forks 213 are staggered to each other so that the supporting forks 421 and the paper-splitting forks 213 will not interfere with each other during the up and down movement. To enable the supporting mechanism 400 to place the folded tissue paper onto the conveyor belt 510, a second cylinder 431 is respectively installed on the sliding blocks 430 on both sides. The cylinder body of the second cylinder 431 is fixedly connected to the sliding block 430, and the push rod of the second cylinder 431 is connected to the fixed plate 420. The second cylinder 431 pushes the fixed plate 420 to slide back and forth. After the supporting mechanism 400 places the folded tissue paper onto the conveyor belt 510, the second cylinder 431 pushes the fixed plate 420, and the fixed plate 420 drives the supporting fork 421 to be pulled out from the bottom of the folded tissue paper. Then, the third servo motor 411 drives the fixed plate 420 to rise, and the second cylinder 431 drives the fixed plate 420 and the supporting fork 421 to reset, so as to carry out the next round of folded tissue paper transportation.

[0058] Part Three mainly describes embodiments of the conveyor belt mechanism 500. In some embodiments of the present invention, such as... Figures 1-4As shown, the conveyor belt mechanism 500 includes a conveyor belt 510 and a conveyor motor 520. The conveyor belt 510 and the conveyor motor 520 are rotatably connected. The conveyor motor 520 is electrically connected to a servo control component. Specifically, the conveyor belt 510 of the conveyor belt mechanism 500 is arranged along the transverse direction of the equipment and transmits data between the two sides of the equipment. Openings are provided on the two sides of the equipment corresponding to the conveyor belt 510. Folded tissues are conveyed out from the openings by the conveyor belt 510 to proceed to the next process. The conveyor motor 520 is rotatably connected to the conveyor belt 510 and drives the conveyor belt 510 to move towards the opening. Under the control of the servo control component, the conveyor motor 520 can cooperate with the support mechanism 400. When the support mechanism 400 places the tissues onto the conveyor belt 510, the servo control component controls the conveyor motor 520 to start, conveying the tissues to the opening. Then the conveyor motor 520 stops, waiting for the support mechanism 400 to move tissues onto the conveyor belt 510 again to repeat the above process.

[0059] It should be understood that using a conveyor belt 510 to transport tissues is not the only implementation method. In some other embodiments, a conveyor belt with a rubber surface can also be used according to actual production needs, as long as the surface of the conveyor belt has sufficient friction to drive the folded tissues. This invention does not elaborate on the surface materials used for the conveyor belt. It should be understood that any flexible changes in the surface material used for the conveyor belt without departing from the basic concept of this invention should be considered within the scope of protection defined by this invention.

[0060] Based on the detailed structural description of the above three parts, the device of the present invention mainly adopts a combination of a swing arm lifting separation mechanism 200, a supporting mechanism 400, and a conveyor belt mechanism 500. Compared with existing automatic paper separating equipment, the device of the present invention can significantly improve the following problems. Existing automatic paper separating equipment generally uses a process of inserting two sets of forks at the front and rear forks for separation. The disadvantage of this separation method is that, since the separated bottom paper has to pass through the gap between the two sets of forks, at least three-quarters of the bottom paper will fall off. The falling is too long and the length of the falling is unstable. The bottom paper is difficult to handle, and the bottom few sheets of paper are not folded neatly, resulting in poor packaging effect. The optimal separation effect for tissues is that half of the bottom paper falls off after separation. To achieve this effect, the device of this invention implements a new separation method, namely, single-sided swing arm insertion separation. The single-sided insertion method solves the problems of excessively long bottom paper falls after separation and unstable fall length. The eccentric wheel connecting rod lifting mechanism solves the problems of uneven tissue folding and unstable tissue separation caused by the large drop difference between the upper plane of the front fork and the folding roller of the folding mechanism 120. The air blowing process solves the problem of poor bottom paper folding effect. This invention enables the device to have the characteristics of stable tissue separation, accurate number of tissues drawn, high efficiency, and excellent folding effect.

[0061] The paper-splitting process of the device of the present invention is as follows: the second servo motor 214 rotates, driving the eccentric wheel 310 to rotate. The rotation of the eccentric wheel 310 drives the first connecting rod 330, which in turn drives the first swing arm 320 to swing. The swing of the first swing arm 320 drives the paper-splitting shaft 212 to rotate. The rotation of the paper-splitting shaft 212 drives the paper-splitting fork to insert, and at the same time, it drives the second swing arms 380 and the second connecting rod 360 on both sides to swing, so that the paper-splitting fork 213 is quickly inserted and quickly raised. When the paper-splitting fork 213 is inserted, the supporting mechanism 400 also quickly descends at the same time, providing sufficient insertion space for the paper-splitting fork 213. After the supporting mechanism 400 puts the separated folded paper into the conveyor belt 510, it quickly returns and opens the air duct mechanism 130 to blow air, blowing up the half of the bottom paper that has fallen after separation, thereby achieving the best folding effect.

[0062] The conveyor belt mechanism 500 is used to transport the paper from the side wall of the equipment. That is, the supporting mechanism 400 places the paper on the conveyor belt 510 in the middle of the equipment and conveys it out. This structure not only saves space and makes the equipment more compact, but also simplifies the operation and makes the subsequent processing more convenient.
