Description

Technical Field

[0001] The invention belongs to the technical field of household paper processing equipment, and in particular relates to a folding device. Background Art

[0002] The outermost tissue in the commonly used pull-out facial tissue, that is, the first tissue pulled out when in use, is usually not folded. Since the opening for pulling out the tissue is set in the middle of the upper end surface of the packaging bag, after packaging, the pulling end of the first tissue will be near the side edge of the tissue packaging bag, and the entire stacked tissue will fill the packaging bag, which makes it difficult to pull out the first tissue and easily causes the packaging bag to be damaged. In order to facilitate the pulling out of the first tissue, currently, a pull-out facial tissue folding machine is usually used to fold the first tissue in the folding process.

[0003] The pull-out facial tissue folder belongs to the front-end equipment of the production line. The existing pull-out facial tissue folder usually folds the first tissue outward. In the subsequent process of the automated production line, the stacked tissues to be packaged have a certain conveying speed, which will cause air flow around them, or when there is a certain amount of wind around the production line, it is easy to make the first tissue folded outward float up, which will cause the first tissue to be scattered or the folding outward to fail, affecting the stability of the subsequent packaging process. In addition, the existing pull-out facial tissue folder usually needs to perform folding-pressing-flipping and other processes to achieve the outward folding of the first tissue. It is not only complex in structure and high in cost, but also complex in folding process, which reduces the efficiency of subsequent packaging.

[0004] In addition, although there are folding machines in the prior art that fold paper towels based on the principles of adsorption and blowing, since facial tissue has certain porosity, the air pressure control accuracy for suction and blowing is high, which increases the production cost and the difficulty of controlling the folding machine. In addition, the adsorbed paper towels are easily detached during the suction process, resulting in folding failure. Summary of the invention

[0047] The present invention will be described below with reference to the accompanying drawings.

[0048] For ease of understanding, the directional terms or qualifiers in this application are all with reference to the drawings to which they refer, and are only for the purpose of facilitating the description of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] Figure 1 The structure of an embodiment of a folding device 1000 according to the present invention is schematically shown. Figure 1 and Figure 2 As shown, the folding device 1000 includes a discharging mechanism 8 and a folding mechanism 100 .

[0050] The discharging mechanism 8 includes a feeding platform 101 for conveying the stacked paper towels 6 , and the moving direction of the stacked paper towels 6 on the feeding platform 101 is perpendicular to the length direction of the stacked paper towels 6 .

[0051] The folding mechanism 100 is disposed above the feeding platform 101 . When the stacked tissues 6 on the feeding platform 101 are transported to the bottom of the folding mechanism 100 , the folding mechanism 100 can fold the first sheet of tissue 61 of the stacked tissues 6 .

[0052] In a specific embodiment, the folding mechanism 100 includes a lifting mechanism 9 and a body 1 .

[0053] Combination Figure 7 As shown, the body 1 is configured as a cuboid structure with a cavity, the bottom surface of the body 1 is formed as a first working surface 11, and one side wall surface of the body 1 is formed as a second working surface 12. A first air suction port 21 and an air blowing port 31 are provided on the first working surface 11, and the air blowing port 31 is close to the second working surface 12. A second air suction port 71 is provided on the second working surface 12, and the second air suction port 71 is close to the first working surface 11.

[0054] The second suction port 71 can generate a first adsorption air pressure to adsorb the edge area of ​​the first paper towel 61 in the stacked paper towel 6, and drive the first paper towel 61 to be lifted outward by rotating the main body 1, so that the edge area of ​​the first paper towel 61 is separated from the next paper towel in the stacked paper towel 6.

[0055] The first suction port 21 can generate a second suction air pressure to suction the first sheet of paper 61 , and the blowing port 31 can generate a blowing air pressure to blow the edge area of ​​the first sheet of paper 61 inwardly.

[0056] The end of the main body 1 is rotatably connected to the lifting mechanism 9 , and the lifting mechanism 9 can drive the main body 1 to move up and down relative to the discharging mechanism 8 .

[0057] The specific working process is as follows.

[0058] After the stacked tissues 6 are transported to the position of the feeding platform 101 corresponding to the folding mechanism 100, the lifting mechanism 9 drives the body 1 to move downward ( Figure 7 to Figure 8 ), thereby making the main body 1 contact with the first piece of tissue paper 61 of the stacked tissue paper 6.

[0059] Afterwards, the first suction port 21 and the second suction port 71 suck the first sheet of paper 61. Fig. 9 After the first paper 61 is adsorbed on the body 1, the body 1 rotates relative to the lifting mechanism 9 and turns over at a certain angle, as shown in FIG. Fig.10 shown.

[0060] Then the air outlet 31 blows air to the first sheet of paper 61, so that the edge area of ​​the first sheet of paper 61 turns inward. Fig.11 shown.

[0061] Finally, the main body 1 is reset, and the first paper 61 after turning over is folded and compacted. Fig.13 The first air inlet 21 and the second air inlet 71 stop inhaling air, and the lifting mechanism 9 drives the body 1 to move upward, and the body 1 is separated from the contact with the stacked paper towels 6, as shown. Fig.14 As shown, the stacked tissues 6 can be transported to the next process.

[0062] In a specific embodiment, Figure 1 , Figure 5 and Figure 6 As shown, the lifting mechanism 9 is provided with two parts, which are symmetrically arranged at both ends of the length direction of the main body 1. Taking the lifting mechanism 9 at one end of the main body 1 as an example, the lifting mechanism 9 includes a lifting plate 91 and a third driving mechanism 96. The third driving mechanism 96 is configured to drive the lifting plate 91 to move up and down relative to the discharge mechanism 8, and the main body 1 is arranged on the lifting plate 91.

[0063] The third driving mechanism 96 includes a lifting guide rail 94 and a guide block 95 slidably arranged on the lifting guide rail 94. The guide block 95 is fixedly connected to the lifting plate 91, and the lifting guide rail 94 is fixedly connected to a fixed frame (not shown in the figure) of the folding device 1000.

[0064] Furthermore, the third driving mechanism 96 also includes two lifting transmission wheels 97 arranged in the vertical direction. It is easy to understand that the two lifting transmission wheels 97 are rotatably arranged on the frame of the folding device 1000. A lifting conveyor belt 98 is arranged between the two lifting transmission wheels 97, and the lifting conveyor belt 98 is fixedly connected to the guide block 95. When the lifting transmission wheel 97 rotates, the lifting conveyor belt 98 can rotate under the drive of the lifting transmission wheel 97, thereby driving the guide block 95 to move. The lifting transmission wheel 97 reciprocates counterclockwise and clockwise respectively, and drives the guide block 95 to move up and down along the lifting guide rail 94 through the lifting conveyor belt 98, so that the body 1 can be moved. Figure 7 and Figure 8 Move between positions.

[0065] According to the present invention, a flip plate 92 is rotatably arranged on the lifting plate 91, and the rotation axis of the flip plate 92 is parallel to the length direction of the body 1. A first driving mechanism 93 is arranged between the lifting plate 91 and the flip plate 92, and the first driving mechanism 93 is configured to drive the flip plate 92 to rotate relative to the lifting plate 91. The body 1 is fixedly arranged on the flip plate 92, so that the first driving mechanism 93 can drive the body 1 to rotate. Figure 5 and Figure 6 ( Fig. 9 and Fig.10 ) between positions.

[0066] In a specific embodiment, the two ends of the first driving mechanism 93 are rotatably connected to the flip plate 92 and the lifting plate 91, respectively, and the first driving mechanism 93 controls the flip plate 92 to rotate relative to the lifting plate 91 by telescopic means. The first driving mechanism 93 can be a cylinder, a hydraulic cylinder, an electric telescopic cylinder, etc.

[0067] like Figure 2 to Figure 4 As shown, in a preferred embodiment, the folding mechanism 100 further includes a paper moving mechanism 4 arranged in the cavity of the body 1 , and a paper moving port 41 for the paper moving mechanism 4 to extend out is provided on the first working surface 11 , and the paper moving port 41 is located between the first air suction port 21 and the air blowing port 31 .

[0068] The paper pulling mechanism 4 is configured to extend the paper pulling port 41 after the edge area of ​​the first paper 61 is turned inwardly, so as to fold and press the first paper 61 inwardly. Fig.12 Under this configuration, after the air outlet 31 turns over the edge of the first sheet of paper 61 by blowing air, the paper-moving mechanism 4 can fold and press the first sheet of paper 61 inward, thereby improving the success rate of folding.

[0069] like Figure 3 and Figure 4As shown, a second driving mechanism 44 is disposed between the flip plate 92 and the paper-moving mechanism 4 , and the second driving mechanism 44 is configured to drive the paper-moving mechanism 4 to move relative to the body 1 .

[0070] The two ends of the second driving mechanism 44 are rotatably connected to the paper-moving mechanism 4 and the flip plate 92, respectively. The second driving mechanism 44 drives the paper-moving mechanism 4 to rotate relative to the flip plate 92 by telescoping, so that the paper-moving mechanism 4 moves relative to the body 1, completing the Figure 3 and Figure 4 ( Fig.11 and Fig.12 ) between the positions. Specifically, the second driving mechanism 44 can be a cylinder, a liquid cylinder or an electric telescopic cylinder.

[0071] Figure 7 The internal structure of the body 1 of the folding mechanism 100 according to the present invention is schematically shown. Figure 7 As shown, the bottom surface of the body 1 is formed as a first working surface 11, and a side wall surface ( Figure 7 The right side wall of the folding mechanism 100 is formed as the second working surface 12. The folding mechanism 100 also includes a first suction port 21 and a blowing port 31 formed on the first working surface 11, and a second suction port 71. The first suction port 21 and the blowing port 31 are formed on the first working surface 11, and the blowing port 31 is arranged at a position close to the second working surface 12. The second suction port 71 is formed on the second working surface 12 and is arranged at a position close to the first working surface 11. The second suction port 71 can generate a first adsorption air pressure to adsorb the edge area of ​​the first sheet of tissue paper 61 in the stacked tissue paper 6, and drive the first sheet of tissue paper 61 to be lifted outward by rotating the body 1, so that the edge area of ​​the first sheet of tissue paper 61 is separated from the next sheet of tissue paper in the stacked tissue paper 6 to achieve paging. The first suction port 21 can generate a second adsorption air pressure to adsorb the middle area of ​​the first sheet of tissue paper 61, specifically the area of ​​the first sheet of tissue paper 61 near the middle fold. The air outlet 31 can generate blowing air pressure to blow the edge area of ​​the first paper 61 inwardly to make the edge area of ​​the first paper 61 hang down, and then the first paper 61 is pressed against the next paper in the stacked paper towel 6 by resetting the body 1. In the present application, the edge area of ​​the first paper 61 refers to the edge of the end of the paper that is drawn when the paper is used.

[0072] In one embodiment, the body 1 can be constructed as a substantially rectangular parallelepiped housing. The body 1 extends longitudinally to a certain length (combined with Figure 1 and Figure 2 For the convenience of explanation, Figure 7 The horizontal direction is defined as the horizontal direction, the vertical direction is defined as the vertical direction, and the direction perpendicular to the paper surface is defined as the longitudinal direction. Figure 7 A cross-section of the body 1 in the longitudinal direction is schematically shown.

[0073] In one embodiment, Figure 7 As shown, the paper-pulling mechanism 4 includes a rotating shaft (not shown), a rotating plate 42 mounted on the rotating shaft, and a finger 43 connected to the end of the rotating plate 42. The paper-pulling mechanism 4 can drive the rotating plate 42 through the rotating shaft to drive the finger 43 to extend out of the paper-pulling port 41, thereby folding the edge area of ​​the first paper 61 inward. Figure 2 As shown, the paper ejection opening 41 is preferably configured as a plurality of through holes evenly spaced and distributed along the longitudinal direction of the first working surface 11. The ejector claw 43 can be configured as an arc plate, a polygonal folded plate (a partial structure with a polygonal cross section), a straight plate, etc. That is, the ejector claw only needs to be able to fold the hanging first paper 61 inward.

[0074] The first end of the rotating plate 42 is configured as an annular connection portion for connecting with the rotating shaft, and the first end of the rotating plate 42 is mounted on the rotating shaft through the annular connection portion. The end of the rotating plate 42 away from the rotating shaft is rotatably connected to the second driving mechanism 44, and the second driving mechanism 44 is rotatably connected to the flip plate 92, so that the second driving mechanism 44 can extend or retract the finger 43 from the paper ejection port 41 by telescoping.

[0075] It should be noted that the paper-moving mechanism 4 is not limited to the specific structure of the present embodiment, and the paper-moving mechanism 4 may also be configured as other structures in the prior art. For example, the paper-moving mechanism 4 may be configured to perform actions according to the following steps: after the paper 61 is sucked by the first air inlet 21 and the second air inlet 71, the paper-moving mechanism 4 first moves toward the paper 61 to separate the paper 61 from the second air inlet 71, so that the paper towel presents a similar Fig.11 Then the paper-moving mechanism 4 moves in a direction parallel to the first working surface 11, driving the paper towel to be further folded; when the end of the paper-moving mechanism 4 moves to a position beyond the first air inlet 21, the paper-moving mechanism 4 moves toward the first working surface 11, pressing the paper 61 to the same position as the first working surface 11. Fig.12 The state similar to the paper drawing 61 in the drawing. This structure should be within the protection scope of the present invention.

[0076] like Figure 7 As shown, a first suction cavity 2 is provided in the cavity of the body 1, a first suction port 21 is connected to the first suction cavity 2, and the first suction cavity 2 is connected to an air source (not shown) and can generate a negative pressure, so that the first suction port 21 can generate a second adsorption air pressure. The first suction cavity 2 extends in the longitudinal direction of the body 1. The air source can be connected to both ends of the longitudinal direction of the body 1 through a gas pipeline, for example.

[0077] Preferably, the first air inlet 21 is configured as a through hole penetrating the first working surface 11. A plurality of first air inlets 21 are provided, and the plurality of first air inlets 21 are evenly distributed in the transverse and longitudinal directions. Figure 7 In the illustrated embodiment, two rows of first air suction ports 21 are arranged at intervals in the transverse direction, and a plurality of first air suction ports 21 in each row are evenly spaced and distributed in the longitudinal direction. Thus, a plurality of first air suction ports 21 form an adsorption area on the first working surface 11 .

[0078] Since the paper of the tissue paper has a certain air permeability, during actual operation, the pressure of the first suction cavity 2 can be adjusted according to actual needs, so as to form a second adsorption air pressure at the first suction port 21. After the first sheet of tissue paper 61 is folded inwards by the paper-moving mechanism 4, the second adsorption air pressure of the first suction port 21 can penetrate the part of the first sheet of tissue paper 61 that is in close contact with the first working surface and adsorb the edge area folded inwards to ensure that the edge area of ​​the first sheet of tissue paper 61 remains in a folded state. According to the present invention, Figure 7 As shown, a second suction cavity 7 is further provided in the cavity of the body 1, and a second suction port 71 is close to the first working surface 11, that is, the second suction port 71 is arranged near the lower edge of the second working surface 12. The second suction port 71 is connected to the air source and can generate negative pressure, so that the second suction port 71 can generate a first adsorption air pressure to adsorb the edge area of ​​the first paper 61.

[0079] Since the paper of the tissue paper has a certain air permeability, in actual operation, the pressure of the second suction cavity 7 can be adjusted according to actual needs, so as to form a first adsorption air pressure and airflow at the second suction port 71, thereby deforming the first sheet of tissue paper 61, and then adsorbing and holding the edge of the first sheet of tissue paper 61, while avoiding adsorbing the next sheet of tissue paper in the stacked tissue paper 6. Then, the first sheet of tissue paper 61 can be brought up by rotating the body 1, so as to separate the first sheet of tissue paper 61 from the next sheet of tissue paper in the stacked tissue paper 6, so as to achieve paging.

[0080] According to the present invention, Figure 7 As shown, a blowing cavity 3 is also provided in the cavity, and the blowing cavity 3 is formed on the inner side wall of the first working surface 11 and is located at one end close to the second suction cavity 7. The first suction cavity 2 extends in the longitudinal direction of the body 1. The blowing port 31 is connected to the blowing cavity 3, and the blowing cavity 3 is connected to the air source and can generate positive pressure, so that the blowing port 31 can generate blowing air pressure. The blowing port 31 is inclined toward the first suction port 21, and its inclination angle can be set to 30°-40°, for example, which is particularly conducive to blowing the edge area of ​​the first paper 61 to flip inward and droop.

[0081] like Figure 1 and Figure 2As shown, the body 1 is provided with joints 13 respectively connected to the first suction cavity 2, the blowing cavity 3 and the second suction cavity 7. Each joint 13 is arranged at the longitudinal end of the body 1, and the other end of each joint 13 is connected to the air pressure control unit (not shown in the figure), so that the air pressure control unit can control the air pressure in the first suction cavity 2, the blowing cavity 3 and the second suction cavity 7 separately.

[0082] It is easy to understand that the air pressure control unit is a prior art and is not the technical point of the present invention, so it will not be described in detail here.

[0083] like Figure 7 As shown, a mounting cavity 5 for mounting a paper-moving mechanism 4 is further provided in the cavity of the body 1, the mounting cavity 5 is arranged between the first air suction cavity 2 and the second air suction cavity 7, and the paper-moving port 41 is communicated with the mounting cavity 5 and is located between the first air suction port 21 and the air blowing port 31. The mounting cavity 5 extends in the longitudinal direction of the body 1. A plurality of paper-moving mechanisms 4 are provided, and are evenly spaced and installed inside the mounting cavity 5 in the longitudinal direction.

[0084] The first working surface 11 and the second working surface 12 may be arranged at a certain angle, for example, 80°-90°. Preferably, the first working surface 11 and the second working surface 12 are arranged perpendicularly. In this way, the paging of the first paper 61 can be effectively realized.

[0085] According to the first embodiment of the present invention, Figure 7 As shown, the first working surface 11 can be constructed to include a plane portion and an inclined portion, the first air suction port 21 and the air blowing port 31 are respectively arranged on the plane portion and the inclined portion, and the paper moving port 41 is arranged at the intersection of the plane portion and the inclined portion. Preferably, the horizontal length of the plane portion is greater than the horizontal length of the inclined portion.

[0086] When the folding mechanism 100 absorbs the first sheet of paper 61 in the stacked tissue 6, the structure of the first working surface 11 is very conducive to the paging of the first sheet of paper 61. At the same time, by making the intersection of the plane part and the inclined part contact the first sheet of paper 61 first, the edge area of ​​the first sheet of paper 61 can have a tendency to bend upward, which is very convenient for the second suction port 71 to absorb the edge area of ​​the first sheet of paper 61 to further promote the paging of the first sheet of paper 61, effectively improving the paper stacking efficiency of the folding mechanism 100 and ensuring the success rate of paper stacking.

[0087] According to the second embodiment of the present invention, Fig.16 As shown, the first working surface 110 of the folding mechanism 200 can be configured as a plane. This structure of the first working surface 110 can also complete the suction paging and folding of the first paper 61.

[0088] According to one embodiment of the present invention, for some extreme working conditions, such as when the conveying speed of the stacked paper towel 6 is too fast, the surrounding air volume is too large, etc., the air outlet 31 can also blow out a moist airflow to humidify the first sheet of paper 61. For example, the air source can be controlled to fill the air blowing cavity 3 with humidified gas, so that the air outlet 31 can blow out a moist airflow to the first sheet of paper 61, so that the folding area of ​​the first sheet of paper 61 is moistened. On the one hand, the weight of the folding area of ​​the first sheet of paper 61 can be increased to facilitate its hanging and blowing it inward for folding. On the other hand, in the subsequent pressing process, the first sheet of paper 61 folded inward can be bonded to the second sheet of paper in the stacked paper towel 6, thereby improving the close fitting effect between the two, further enhancing the folding effect of the first sheet of paper 61, and being very helpful in preventing it from flying up or being scattered in the subsequent packaging process.

[0089] The specific working process of the folding mechanism 100 of the present invention will be described in detail below with reference to the accompanying drawings.

[0090] In actual operation, the folding mechanism 100 can be used in an automated tissue production line as part of a tissue production process. Figure 7 As shown, the stacked tissue 6 to be packaged moves to a position directly below the folding mechanism 100 through the production line to be aligned with the folding mechanism 100, so that the first sheet of tissue 61 to be packaged is directly below the first working surface 11 of the body 1. At this time, the first suction cavity 2, the blowing cavity 3 and the second suction cavity 7 are not supplied with air pressure.

[0091] like Figure 8 As shown, the third driving mechanism 96 drives the folding mechanism 100 to move downward to approach the stacked paper towels 6. In order to facilitate the adsorption of the first sheet of paper 61 to achieve paging, preferably, the body 1 of the folding mechanism 100 can be tilted at a certain angle, so that the intersection of the plane part and the inclined part of the first working surface 11 first contacts the first sheet of paper 61, thereby pressing down the first sheet of paper 61, so that the edge area of ​​the first sheet of paper 61 has the effect of slightly tilting upward, which is very convenient for adsorption and can further improve the paging effect. Figure 8 The direction indicated by the arrow a in FIG. 1 is the direction in which the folding mechanism 100 moves downward.

[0092] like Fig. 9As shown, when the folding mechanism 100 moves downward to make the first working surface 11 contact the first sheet of paper 61 of the stacked paper towel 6, the air pressure control unit controls the second suction cavity 7 to generate negative pressure, so as to form a first adsorption air pressure at the second suction port 71, so that the second suction port 71 adsorbs the edge of the first sheet of paper 61 and folds it up, thereby separating the first sheet of paper 61 from the next sheet of paper in the stacked paper towel 6, so that the first sheet of paper 61 is paginated and remains adsorbed. It should be understood that the edge of the first sheet of paper 61 is partially exposed in the horizontal direction relative to the first working surface 11, so that the second suction port 71 can adsorb the first sheet of paper 61.

[0093] Afterwards, if Fig.10 As shown, the first driving mechanism 93 controls the main body 1 to rotate 90 degrees counterclockwise, so that the first working surface 11 rotates 90 degrees counterclockwise. Thus, the main body 1 rotates 90 degrees counterclockwise by sucking the first paper 61 through the second suction port 71.

[0094] Afterwards, if Fig.11 As shown, the air pressure control unit controls the first suction cavity 2 to generate negative pressure, so as to form a second adsorption air pressure at the first suction port 21, so that the first suction port 21 adsorbs the first sheet of paper 61. Of course, it can be understood that the first suction port 21 can also open the adsorption pressure to adsorb the first sheet of paper 61 during the rotation of the body 1.

[0095] Then, the pressure in the second suction cavity 7 is closed by the air pressure control unit, and at the same time, the positive pressure in the blowing cavity 3 is controlled to generate blowing pressure at the blowing port 31. Fig.11 As shown, at this time, the second air inlet 71 loses the adsorption of the edge of the first paper 61, and the edge area of ​​the first paper 61 turns inward (clockwise) under the action of the blowing pressure and is in a hanging state. In this process, the first air inlet 21 keeps adsorbing the first paper 61.

[0096] Afterwards, if Fig.12 As shown, the first suction port 21 still maintains the suction of the first paper 61. At the same time, the paper pulling mechanism 4 is controlled to rotate by the second driving mechanism 44, so that the finger 43 extends from the paper pulling port 41, so that the edge area of ​​the first paper 61 is folded inward, and the finger 43 can work together with the first working surface 11 to form a compact fold on the first paper 61, and then the finger 43 is quickly retracted. At the same time, the pressure in the blowing cavity 3 is turned off by the air pressure control unit. As a result, the folding mark of the first paper 61 folding inward is formed near the paper pulling port 41.

[0097] Afterwards, if Fig.13As shown, the main body 1 is controlled by the transmission mechanism to rotate 90 degrees as a whole to reset. In this process, the adsorption airflow of the first suction port 21 can pass through the part of the first sheet of paper 61 that is in close contact with the first working surface 11 and adsorb the inward folded edge area of ​​the first sheet of paper 61 to keep the edge area of ​​the first sheet of paper 61 always in a folded state. Then the main body 1 is controlled to press down the first sheet of paper 61 to ensure the folding effect, so that the first sheet of paper 61 is folded inward, thereby achieving the inward folding of the first sheet of paper 61. Afterwards, the pressure in the first suction cavity 2 is closed by the air pressure control unit, and the adsorption of the first suction port 21 on the first sheet of paper 61 is removed. Fig.13 The arrow b in the figure indicates the downward pressure applied. Since the intersection of the plane part and the inclined part of the first working surface 11 exerts downward pressure on the first sheet of tissue paper 61, the pressing effect is manifested as an inward depression of the middle part of the first sheet of tissue paper 61 after being folded inward, which is very helpful to prevent the first sheet of tissue paper from flying up in the subsequent packaging process and can significantly reduce the impact of the surrounding environment on the subsequent packaging process.

[0098] Afterwards, if Fig.14 and Fig.15 As shown, the third driving mechanism 96 controls the body 1 to move upward away from the stacked paper towels 6, and the stacked paper towels 6 move to the next process through the production line. Fig.14 The arrow c in the figure indicates the upward direction of the body 1. Fig.14 and Fig.15 The arrow d in the figure indicates the direction in which the stacked tissue 6 moves to the next process. Thus, the folding mechanism 100 completes the inward folding of the first sheet of paper 61 in the stacked tissue 6.

[0099] In the second embodiment, if Fig.16 As shown, for the folding mechanism 200 in which the first working surface 110 is configured as a plane, its working principle and process are the same as those of the first embodiment, and will not be described in detail here.

[0100] Of course, it is understandable that in the second embodiment, since the first working surface 110 is configured as a plane, when the folding mechanism 200 is controlled to move downward, the first working surface 110 is controlled to remain horizontal, and the edge of the first sheet of paper 61 is ensured to be partially exposed in the horizontal direction relative to the first working surface 110. Similarly, the edge area of ​​the first sheet of paper 61 is adsorbed by the second suction port 710 to enable the first sheet of paper 61 to be paginated. Moreover, when the main body 10 presses down the stacked tissue 6, the intersection of the first working surface 110 and the second working surface 120 can also cause the edge area of ​​the first sheet of paper 61 to have a slightly upward tilting effect, so that the second suction port 710 can adsorb the first sheet of paper 61.

[0101] The folding mechanism 100 according to the present invention can quickly and effectively fold the first sheet of tissue paper 61 in the stacked tissue paper 6 to be packaged inwardly and press it, so as to prevent the first sheet of tissue paper 61 from flying up in the subsequent packaging process, and after the packaging is completed, the extraction end of the first sheet of tissue paper 61 can be located in the middle position of the packaging bag (i.e., the opening position), which is very convenient for extracting and using the first sheet of tissue paper 61. At the same time, the use of the folding mechanism 100 can effectively simplify the folding process, which is very helpful to improve the folding efficiency of the stacked tissue paper 6 and ensure the folding success rate. In addition, the folding mechanism 100 has a simple structure and low cost.

[0102] According to the present invention, a specific embodiment of a discharging mechanism 8 is also provided.

[0103] Fig.17 The structure of the discharging mechanism 8 according to the present invention is shown. Fig.17 As shown, the discharging mechanism 8 includes a feeding platform 101 , a moving mechanism 104 , a vertical motion mechanism 103 and a material shifting mechanism 102 .

[0104] like Fig.17 and Fig. 20 As shown, in this embodiment, the feeding platform 101 is designed to be in the shape of a cuboid. The directions described by "up" and "down" in this embodiment are defined as the height direction of the feeding platform 101; the directions described by "left" and "right" in the present invention are defined as the length direction of the feeding platform 101; the directions described by "front" and "rear" in the present invention are defined as the width direction of the feeding platform 101.

[0105] The length direction of the stacked paper towels 6 is parallel to the length direction of the feeding platform 101 .

[0106] A plurality of guide grooves 1011 are provided on the feeding platform 101. These guide grooves 1011 penetrate the feeding platform 101 in the vertical direction, and the guide grooves 1011 are parallel to each other, and the length direction of each guide groove 1011 is parallel to the width direction of the feeding platform 101. In other words, the length direction of the guide groove 1011 in this embodiment points to the front-rear direction.

[0107] like Fig.17 and Fig.18 As shown, the moving mechanism 104 is arranged below the feeding platform 101, and a material-dispensing mechanism 102 is arranged above the moving mechanism 104. The top end of the material-dispensing mechanism 102 passes through the guide groove 1011 and extends to the top of the feeding platform 101. The moving mechanism 104 can drive the material-dispensing mechanism 102 to move along the length direction of the guide groove 1011, thereby dispensing the stacked paper towels 6 on the feeding platform 101.

[0108] The vertical motion mechanism 103 is disposed between the moving mechanism 104 and the material-digging mechanism 102 , and the vertical motion mechanism 103 can drive the material-digging mechanism 102 to move in a vertical direction.

[0109] Further, in this embodiment, a conveyor belt mechanism 105 is provided at the front end of the feeding platform 101, and the conveying direction of the conveyor belt mechanism 105 is parallel to the length direction of the feeding platform 101. The conveying surface of the conveyor belt mechanism 105 is flush with the upper end surface of the feeding platform 101, or the conveying surface of the conveyor belt mechanism 105 is slightly lower than the upper end surface of the feeding platform 101.

[0110] In the actual working process, the stacked paper towels 6 formed by the folding roller (not shown in the figure, the folding roller is prior art and will not be described here) will fall on the Fig.17 The first position 1012 in the feeding platform 101 is the rear upper end of the feeding platform 101. The vertical motion mechanism 103 then drives the material-dispensing mechanism 102 to move upward until the top of the material-dispensing mechanism 102 passes through the guide slot 1011 and is higher than the upper end surface of the feeding platform 101. Preferably, the top height of the material-dispensing mechanism 102 is not lower than the height of the stacked paper towels 6 stacked at the first position 1012. Subsequently, the moving mechanism 104 drives the material-dispensing mechanism 102 to move forward along the length direction of the guide slot 1011 to convey the first stacked paper towels 6. The first stacked paper towels 6 are conveyed to the feeding platform 101. Fig.17 The second position 1013 in the feeding platform 101. The second position 1013 can be any position that does not interfere with the first position 1012 of the feeding platform 101.

[0111] After the material-dispensing mechanism 102 delivers the first stack of paper towels 6 to the second position 1013, the vertical motion mechanism 103 drives the material-dispensing mechanism 102 to descend until the upper end of the material-dispensing mechanism 102 is lower than the lower end surface of the stack of paper towels 6, and then the moving mechanism 104 drives the material-dispensing mechanism 102 to return to the lower side of the first position 1012 along the original path, during which time the folding roller folds another stack of paper towels 6 and has fallen to the first position of the feeding platform 101. The material-dispensing mechanism 102 moves upward again driven by the vertical motion mechanism 103 until the upper end of the material-dispensing mechanism 102 passes through the guide groove 1011 and exceeds the upper end surface of the stack of paper towels 6, and then the moving mechanism 104 drives the material-dispensing mechanism 102 to move forward again. At this time, the material transfer mechanism 102 pushes one stacked paper towel 6 to the second position 1013 on the one hand, and pushes another stacked paper towel 6 to the conveying surface (third position 1016) of the conveyor belt mechanism 105 on the other hand. The conveyor belt mechanism 105 then transports the stacked paper towel 6 to the next process.

[0112] Driven by the vertical motion mechanism 103 and the moving mechanism 104, the material-dispensing mechanism 102 reciprocates in this way, and sequentially pushes the stacked paper towels 6 from the first position 1012 to the second position 1013 and the third position 1016. This structure of the present invention allows the stacked paper towels 6 to stay at the second position 1013 for a period of time, and the body 1 of the present invention is set at the position corresponding to the second position 1013. During the period when the stacked paper towels 6 stay at the second position 1013, the body 1 sequentially executes the operations from the first position 1012 to the second position 1013 and the third position 1016. Figure 8 to Figure 15 A series of actions are performed to complete the folding of the first layer of tissue paper 61.

[0113] In a specific embodiment, Fig.17 and Fig.19 As shown, the material shifting mechanism 102 includes a plurality of material shifting forks 1021, and the material shifting forks 1021 are adapted to the guide grooves 1011. That is, the number of the material shifting forks 1021 is consistent with the number of the guide grooves 1011, and a corresponding material shifting fork 1021 is arranged in each guide groove 1011. The plurality of material shifting forks 1021 and the guide grooves 1011 can be arranged to push the stacked paper towels 6 more stably.

[0114] Furthermore, the material shifting fork 1021 includes at least two material shifting teeth 1022 , and the plurality of material shifting teeth 1022 are sequentially arranged along the length direction of the guide groove 1011 . In this embodiment, each material shifting fork 1021 includes three material shifting teeth 1022 .

[0115] Combination Fig.17 As shown, two adjacent material-selecting teeth 1022 are used to place the stacked paper towels 6, that is, the lateral distance (first distance 1014) between the two material-selecting teeth 1022 is adapted to the width of the stacked paper towels 6, and the lateral distance (second distance 1015) between the two adjacent material-selecting teeth 1022 is used to extend the distance between the front and rear end faces of the material-selecting fork 1021. When the material-selecting fork 1021 just moves from bottom to top to limit the stacked paper towels 6 at the first position 1012 within the first distance 1014, the rear end face of the stacked paper towels 6 at the second position 1013 just contacts the front end face of the material-selecting fork 1021. When the material-selecting fork 1021 pushes the stacked paper towels 6 originally at the first position 1012 to the second position 1013, the front end face of the material-selecting fork 1021 simultaneously pushes the stacked paper towels 6 originally at the second position 1013 to the third position 1016.

[0116] like Fig.18 and Fig.19As shown, in a specific embodiment, the material shifting mechanism 102 also includes a mounting bar 1023, and the length direction of the mounting bar 1023 is perpendicular to the length direction of the guide groove 1011, that is, the length direction of the mounting bar 1023 is parallel to the length direction of the feeding platform 101, and a plurality of material shifting forks 1021 are distributed in sequence along the length direction of the mounting bar 1023.

[0117] Combination Fig.17 , Fig.18 and Fig.19 As shown, the vertical motion mechanism 103 includes a vertically arranged vertical motion cylinder 1031 and a vertical motion guide rod 1032 , and the upper and lower ends of the vertical motion cylinder 1031 and the vertical motion guide rod 1032 are respectively connected to the moving mechanism 104 and the material shifting mechanism 102 .

[0118] Specifically, the present embodiment is provided with two vertical motion guide rods 1032, which are respectively arranged on the left and right sides of the vertical motion cylinder 1031. The upper ends of the vertical motion guide rods 1032 and the vertical motion cylinder 1031 are fixedly connected to the bottom surface of the mounting bar 1023, and the lower ends of the vertical motion guide rods 1032 and the vertical motion cylinder 1031 are fixedly connected to the moving platform 1042 of the moving mechanism 104.

[0119] like Fig.17 and Fig.18 As shown, the moving mechanism 104 includes a fixed base 1041 and a moving platform 1042 movably arranged on the fixed base 1041 , and the moving direction of the moving platform 1042 is parallel to the length direction of the guide groove 1011 .

[0120] Furthermore, the movable platform 1042 is connected to the fixed base 1041 through a slide rail 1043, and the length direction of the slide rail 1043 is parallel to the length direction of the guide groove 1011. In this embodiment, two slide rails 1043 are provided, which are parallel to each other and symmetrically arranged at the left and right parts of the lower end of the movable platform 1042.

[0121] Two conveyor belt wheels 1044 are rotatably arranged on the fixed base 1041, and the line connecting the centers of the two conveyor belt wheels 1044 is parallel to the length direction of the guide groove 1011. A connecting belt 1045 is arranged on the two conveyor belt wheels 1044, and the connecting belt 1045 is fixedly connected to the moving platform 1042. The conveyor belt wheels 1044 drive the moving platform 1042 to move forward or backward through the connecting belt 1045 by rotating alternately forward and reverse.

[0122] Furthermore, a driver 1046 is fixedly disposed at the lower end of the fixed base 1041 , and the driver 1046 is drivingly connected to one of the conveyor belt wheels 1044 , so that the conveyor belt wheel 1044 can be driven to rotate by the driver 1046 .
