Description

Technical Field

[0001] This invention relates to the field of folding devices, and more particularly to a folding system. Background Technology

[0002] Wet wipes are a very convenient type of handkerchief. They are divided into two types based on their material: cloth and paper. Cloth or paper wipes are made by adding liquid materials such as purified water, perfume, or alcohol. Cloth wipes are produced by cutting and adding liquids to a whole roll of cloth. Compared to paper wipes, wet wipes have a certain degree of moisture, making them more effective at removing dirt and dust.

[0003] In the production and processing of paper wipes, the conveyed paper towels typically require reciprocating folding. During this folding process, two rotating folding rollers mounted on the frame typically create creases in the conveyed paper towels, ensuring better folding quality in subsequent folding. The two folding rollers are usually positioned on either side of the conveyed paper towels. One roller has a fixed crease-forming section, while the other has a crease-forming groove. As the paper towels are conveyed, the rotation of the two rollers pushes the paper towels into the crease-forming groove. Within the groove, the crease-forming section compresses the conveyed paper towels to create creases.

[0004] The crease forming section mainly forms creases on the paper by squeezing against the wall of the crease forming groove. During this process, the crease forming section is prone to damage to the paper towel due to squeezing and friction against the wall of the crease forming groove while pushing and folding the paper towel, which makes it difficult to achieve stable folding of the paper towel. Summary of the Invention

[0005] In order to prevent the paper towels from being damaged during the feeding and folding process, and thus achieve stable folding of the paper towels, this application provides a folding system.

[0006] The folding system provided in this application adopts the following technical solution: A folding system includes a first folding roller and a second folding roller rotatably mounted on a frame. The outer circumferential surface of the first folding roller is provided with a plurality of clamping grooves distributed around its own axis. The outer circumferential surface of the second folding roller is movably provided with push teeth that correspond one-to-one with the clamping grooves. The push teeth are used to push the conveyed paper into the clamping grooves. The clamping grooves are provided with clamping teeth. When the push teeth are located in the clamping grooves, the clamping teeth are located at the bottom of the push teeth. The second folding roller is provided with a push elastic component that presses the push teeth toward the clamping teeth.

[0007] By adopting the above technical solution, when the paper passes between the first folding roller and the second folding roller, the pusher tooth feeds the paper into the clamping groove, and the crease of the paper is formed by the extrusion between the pusher tooth and the clamping tooth in the clamping groove. During the crease formation process, the elastic force of the pusher elastic component allows the pusher tooth to buffer the paper to a certain extent when it is folded, reducing the relative extrusion force between the pusher tooth and the clamping tooth. This makes it less likely that the paper towel will be damaged due to extrusion and friction during the folding process, and facilitates the stable folding of the paper towel.

[0008] Optionally, the outer circumferential surface of the second folding roller is provided with a receiving groove for accommodating the push tooth. The push tooth is rotatably engaged in the receiving groove. The push elastic component includes a push spring and a push screw. The push screw is threadedly engaged with the second folding roller. The push tooth is provided with a movable groove on the side facing the push screw. One end of the push screw passes through and slides into the movable groove. The push spring is sleeved on the outside of the push screw and applies an elastic force to the push tooth to move towards one of the groove walls of the receiving groove.

[0009] By adopting the above technical solution, the setting of the receiving groove facilitates the stable receiving of the push tooth and limits the rotation of the push tooth, thereby helping to ensure the stability of the push tooth when pushing the paper. The push spring and push screw facilitate the application of a stable elastic force to the push tooth.

[0010] Optionally, the outer circumferential surface of the second folding roller is provided with mounting grooves that correspond one-to-one with the receiving grooves, and each mounting groove is connected to each receiving groove, with one end of the push screw bolt head located inside the mounting groove.

[0011] By adopting the above technical solution, the installation slot facilitates the quick installation of the push screw by the staff and ensures the stability of the position of the push screw after installation.

[0012] Optionally, the push teeth, push elastic components, receiving grooves, and mounting grooves are all evenly distributed in multiple sets along the axial direction of the second folding roller.

[0013] By adopting the above technical solution, the setting of multiple sets of push teeth to push the paper is beneficial in two ways: firstly, it can maintain or replace one of the push teeth when it wears out, while ensuring the uniformity of the force when the paper is pushed, thus reducing subsequent maintenance costs; secondly, it makes the installation of the push teeth less likely to occupy the installation space at the end of the second folding roller, thus making the installation more versatile.

[0014] Optionally, the outer circumferential surface of the second folding roller is provided with a receiving groove corresponding to the push tooth, the push tooth is slidably engaged in the receiving groove, and the push tooth extends along the axis of the second folding roller; the push elastic component includes a push slider and a push spring, the outer circumferential surface of the second folding roller is provided with a push groove communicating with the receiving groove, the push slider is slidably engaged in the push groove, the push spring is located between the groove wall of the push groove and the push slider, and one end of the push tooth is fixedly installed on the push slider.

[0015] By adopting the above technical solution, the setting of the receiving slide groove facilitates the stable receiving of the push tooth and limits the sliding of the push tooth. The integral push tooth facilitates the stable pushing of the paper. At the same time, the push spring can stably press the push tooth through the elastic force of the push slider. The structure is simple and easy to use.

[0016] Optionally, the push elastic component further includes a push guide rod, which is mounted on the receiving slide groove wall, and the push spring is sleeved on the push guide rod.

[0017] By adopting the above technical solution, the push guide rod plays a guiding role for the push spring, which helps to further ensure the stability of the push spring's application of elastic force to the push slider.

[0018] Optionally, the first folding roller is provided with a material-clamping rotation assembly that drives the clamping teeth to rotate. When the top push tooth is located in the clamping groove, the material-clamping rotation assembly drives the clamping teeth to rotate to the position where they press against the top push tooth.

[0019] By adopting the above technical solution, the setting of the material clamping and rotating component further reduces the relative squeezing force between the push tooth and the material clamping tooth, making it less likely for the paper towel to be damaged due to squeezing and friction during the folding process, thus further ensuring the forming quality of the paper towel crease.

[0020] Optionally, the material clamping rotation assembly includes a material clamping fixing seat, a material clamping rotating seat, a material clamping spring, a material clamping rotating rod, a material clamping connecting rod, and a material clamping drive seat. The material clamping fixing seat is fixedly installed on the frame, and the material clamping rotating seat is fixedly installed on one end of the second folding roller and rotatably installed on the material clamping fixing seat. The material clamping teeth are fixedly installed on the material clamping rotating rod, the material clamping rotating rod passes through and is rotatably installed on the material clamping rotating seat, and the material clamping connecting rod is fixedly installed on the material clamping rotating rod. One end of the material clamping spring is connected to the material clamping connecting rod, and the other end is connected to the material clamping rotating seat. The material clamping drive seat is located at the end of the material clamping connecting rod away from the material clamping spring. The material clamping rotating rod is located between the material clamping spring and the material clamping drive seat. The material clamping drive seat abuts against the material clamping fixing seat under the elastic force of the material clamping spring. The material clamping fixing seat is provided with a material clamping guide groove corresponding to the material clamping drive seat. When the material clamping drive seat is located in the material clamping guide groove, the material clamping teeth rotate to the position where they press against the top of the push tooth.

[0021] By adopting the above technical solution, during the rotation of the material clamping rotating seat, the material clamping drive seat continuously cooperates with the material clamping guide groove to automatically realize the rotation of the material clamping teeth toward the top push teeth. In this process, no additional drive source is required, which is convenient and fast.

[0022] Optionally, multiple clamping teeth and clamping grooves are evenly distributed along the axis of the first folding roller, and the clamping grooves are provided with anti-slip protrusions on the side facing the clamping teeth; the clamping drive seat includes a drive rod and a drive roller, the drive rod is fixedly installed on the clamping connecting rod, and the drive roller is rotatably installed on the drive rod.

[0023] By adopting the above technical solution, the cooperation of multiple clamping teeth and clamping grooves facilitates more stable positioning when paper is folded. At the same time, the anti-slip ridges help ensure the stability of paper clamping after folding. In addition, the setting of the drive roller reduces the friction between the clamping drive seat and the clamping fixed seat, which helps to ensure the driving stability and service life of the clamping drive seat.

[0024] Optionally, the first folding roller and the second folding roller have the same structure, and both the first folding roller and the second folding roller are provided with clamping grooves, pushing teeth, pushing elastic components and clamping teeth on their outer peripheral surfaces.

[0025] By adopting the above technical solution, the alternating arrangement of the first folding roller and the second folding roller facilitates folding at different positions on both sides of the conveyed paper, making it easy to adapt to more different folding situations and highly applicable.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During the crease forming process of the paper towel, the setting of the push elastic component reduces the relative squeezing force between the push tooth and the clamping tooth, so that the paper towel is less likely to be damaged due to squeezing and friction during the folding process, which facilitates the stable folding of the paper towel.

[0027] 2. The movement of the clamping teeth driven by the clamping rotation component further reduces the relative squeezing force between the pusher teeth and the clamping teeth, making it less likely for the paper towels to be damaged due to squeezing and friction during the folding process, thus further ensuring the forming quality of the paper towel creases.

[0028] 3. During the rotation of the material clamping rotating seat, the material clamping drive seat continuously cooperates with the material clamping guide groove to automatically realize the rotation of the material clamping teeth toward the top push teeth. In this process, no additional drive source is required, which is convenient and fast. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0039] Example 1.

[0040] This application discloses a folding system. (Refer to...) Figure 1 and Figure 2 The folding system includes a first folding roller 1 and a second folding roller 2 rotatably mounted on the frame. The outer circumferential surface of the first folding roller 1 is provided with multiple sets of clamping grooves 3 evenly distributed around its own axis. In this embodiment, the number of clamping grooves 3 is selected as four sets. Each set of clamping grooves 3 has multiple clamping grooves evenly distributed around the axis of the first folding roller 1. Each clamping groove 3 is provided with a material clamping tooth 4. Specifically, the material clamping tooth 4 is rotatably engaged with the first folding roller 1. The first folding roller 1 is provided with a material clamping rotation assembly that drives the material clamping tooth 4 to rotate.

[0041] Reference Figure 2 and Figure 3 Two sets of clamping rotating assemblies are provided corresponding to the first folding roller 1 and are respectively located near the two ends of the first folding roller 1. The clamping rotating assemblies include clamping fixing seat 5, clamping rotating seat 6, clamping spring 7, clamping rotating rod 8, clamping connecting rod 9, and clamping driving seat 10. The clamping fixing seat 5 is fixedly installed on the frame (not shown in the figure) by bolts. The clamping rotating seat 6 is coaxially fixedly installed on one end of the first folding roller 1 and is rotatably installed on the clamping fixing seat 5.

[0042] Continue to refer to Figure 2 and Figure 3In this embodiment, four clamping rods 8 are evenly distributed circumferentially around the axis of the first folding roller 1. Each clamping rod 8 passes through and rotatably engages with the clamping rotating seat 6, so that each clamping rod 8 can rotate around the axis of the first folding roller 1 together with the clamping rotating seat 6 and can rotate around its own axis. Further, the clamping tooth 4 includes a clamping fixing part 401 and a clamping tooth limiting part 402 fixedly connected to the clamping fixing part 401. The clamping tooth limiting part 402 is made of rubber and is injection molded onto the clamping fixing part 401 to reduce wear caused by rigid friction between the clamping tooth limiting part 402 and the conveying paper. Each clamping slot 3 has its clamping fixing part 401 fixedly installed on the same clamping rotating rod 8, so that when one of the clamping rotating rods 8 rotates around its own axis, each clamping tooth 4 in each clamping slot 3 rotates together, so that each clamping tooth 4 can be positioned by the clamping tooth limiting part 402 when processing the paper crease.

[0043] Continue to refer to Figure 2 and Figure 3 There are four sets of clamping connecting rods 9 and clamping rotating rods 8, each set having two clamping connecting rods 9, which are fixedly installed at both ends of the clamping rotating rod 8 along its length. Specifically, the clamping connecting rod 9 includes a first clamping part 901 and a second clamping part 902 fixedly connected to the first clamping part 901. Both the first clamping part 901 and the second clamping part 902 are elastic, and each of the sides of the first clamping part 901 and the second clamping part 902 that are close to each other has an installation half-groove 11 that matches the shape of the clamping rotating rod 8. When the clamping rotating rod 8 is inserted into the installation half-groove 11 of the first clamping part 901 and the second clamping part, the first clamping part 901 and the second clamping part 902 are fixed by bolts, so that the first clamping part 901 and the second clamping part 902 clamp the clamping rotating rod 8, thus achieving a stable fixation between the clamping connecting rod 9 and the clamping rotating rod 8. This fixing method has a simple structure, is easy to disassemble and assemble, and facilitates subsequent maintenance of the clamping connecting rod 9.

[0044] Reference Figure 3 One end of the clamping spring 7 is connected to the clamping connecting rod 9, and the other end is connected to the clamping rotating seat 6. The clamping drive seat 10 is located at the end of the clamping connecting rod 9 away from the clamping spring 7. The clamping rotating rod 8 is located between the clamping spring 7 and the clamping drive seat 10, so that the clamping drive seat 10 moves towards the clamping fixed seat 5 under the elastic force of the clamping spring 7. To ensure the stability of the elastic force applied by the clamping spring 7 to the clamping drive seat 10, a clamping guide rod 12 is fixedly installed on the clamping connecting rod 9. The clamping spring 7 is sleeved on the clamping guide rod 12, so that the clamping guide rod 12 plays a certain limiting role for the clamping spring 7.

[0045] Reference Figure 2 and Figure 3Furthermore, the material clamping drive seat 10 includes a drive rod 101 and a drive roller 102. The drive rod 101 is fixedly installed on the material clamping connecting rod 9, and the drive roller 102 is coaxially rotatably installed on the drive rod 101. Under the elastic force of the material clamping spring 7, the drive roller 102 abuts against and rolls against the material clamping fixing seat 5. The clamping base 5 includes a base body 51 and a clamping fixing part 52 that is fixedly installed on one side of the base body 51 by bolts. The clamping fixing part 52 is provided with a clamping guide groove 13 corresponding to the drive roller 102 of the clamping drive base 10. When the clamping drive base 10 rotates to the position of the clamping guide groove 13, the clamping drive base 10 drives the clamping connecting rod 9 to rotate, which in turn drives the clamping rotating rod 8 and each clamping tooth 4 in one set of clamping grooves 3 to rotate together. This further facilitates the stable clamping of the conveyed paper by each clamping tooth 4 through the pressure of the conveyed paper. When the clamping drive base 10 disengages from the clamping guide groove 13, each clamping tooth 4 in one set of clamping grooves 3 releases the clamping of the paper, thereby facilitating the conveyed paper to be sent to the next station for processing.

[0046] Reference Figure 4 and Figure 5 The outer circumferential surface of the second folding roller 2 is provided with four receiving grooves 14 that correspond one-to-one with the clamping grooves 3. Each receiving groove 14 is slidably provided with a pusher tooth 15. Each pusher tooth 15 corresponds one-to-one with each clamping groove 3 of the first folding roller 1. In this embodiment, the pusher tooth 15 extends along the axis of the second folding roller 2. The second folding roller 2 is provided with a push elastic component that presses against the push tooth 15. In this embodiment, two sets of push elastic components are provided and are respectively located near the two ends of the second folding roller 2 in the length direction. Specifically, the push elastic component includes a push slider 16 and a push spring 17. A push groove 18 is opened on the outer peripheral surface of the second folding roller 2. The push groove 18 is connected to the receiving groove 14. The push slider 16 slides and cooperates with the push groove 18. One end of the push tooth 15 is fixedly installed on the push slider 16. One end of the push spring 17 is connected to the groove wall of the push groove 18 and the other end is connected to the push slider 16, so that the push spring 17 plays a buffering role when the push slider 16 slides in the push groove 18.

[0047] Reference Figure 5 To further ensure the stability of the elastic force applied by the push spring 17, the push elastic component also includes a push guide rod 24. The push guide rod 24 is fixedly mounted on the groove wall of the receiving slide 14, and the push spring 17 is sleeved on the push guide rod 24 to limit the position of the push spring 17.

[0048] Reference Figure 3 and Figure 5When the paper is positioned between the first folding roller 1 and the second folding roller 2, and the first folding roller 1 and the second folding roller 2 rotate in opposite directions around their own axes, the first folding roller 1 and the second folding roller 2 drive the paper to be conveyed. During the paper conveying process, each push tooth 15 can drive the paper to be clamped into each clamping groove 3, and the paper is creased by mutual compression with the clamping teeth 4 in the clamping groove 3. Specifically, when the push tooth 15 is located in the clamping groove 3, the clamping teeth 4 in the clamping groove 3 are located at the bottom of the push tooth 15, and the push spring 17 is located on the side of the push tooth 15 away from the clamping teeth 4. Each clamping groove 3 has an anti-slip protrusion 19 on the side facing the clamping teeth 4 in the clamping groove 3, so as to increase the friction between the groove wall of the clamping groove 3 and the paper being conveyed, thereby further ensuring the stability of the clamping teeth 4 when clamping the paper after the paper is creased.

[0049] The implementation principle of Embodiment 1 of this application is as follows: when the paper is creased, the paper is conveyed between the first folding roller 1 and the second folding roller 2. The push tooth 15 feeds the paper into the clamping groove 3, and the crease of the paper is formed by the compression between the push tooth 15 and the clamping tooth 4 in the clamping groove 3. During the crease formation process, the elastic force of the push spring 17 and the clamping spring 7 allows the push tooth 15 and the clamping tooth 4 to buffer to a certain extent when the paper is folded, thereby effectively reducing the relative compression force between the push tooth 15 and the clamping tooth 4. This makes it less likely that the paper towel will be damaged due to compression and friction during the folding process, and facilitates the stable folding of the paper towel.

[0050] Example 2.

[0051] Reference Figure 6 The main difference between this embodiment and Embodiment 1 is that the setting of the push elastic component is different. In this embodiment, the first folding roller 1 and the second folding roller 2 have the same structure. The outer peripheral surfaces of the first folding roller 1 and the second folding roller 2 are provided with clamping grooves 3, push teeth 15, push elastic components and clamping teeth 4. The push teeth 15 and clamping teeth 4 of the first folding roller 1 and the second folding roller 2 are alternately distributed around their own axes.

[0052] To facilitate the structural description of specific components, this application embodiment still uses the second folding roller 2 as a reference to elaborate on the specific structure of the push elastic component in this application. The outer peripheral surface of the second folding roller 2 is provided with a receiving groove 23 for receiving the push teeth 15, and each push tooth 15 is rotatably engaged in the receiving groove 23.

[0053] Reference Figure 7 and Figure 8The push-elastic component includes a push-spring 17 and a push-screw 20. The push-screw 20 is threaded onto the second folding roller 2. The push-tooth 15 has a movable groove 21 on the side facing the push-screw 20. One end of the push-screw 20 passes through the receiving groove 23 and the movable groove 21 in sequence and slides with the movable groove 21. The groove diameter of the movable groove 21 is larger than the cross-sectional diameter of the push-screw 20 to facilitate the sliding of the push-screw 20 in the movable groove 21. The push-spring 17 is sleeved on the push-screw 20 and applies a spring force to the push-tooth 15, causing it to move towards one of the groove walls of the receiving groove 23, so that the push-spring 17 plays an elastic buffering role against the push-tooth 15.

[0054] Reference Figure 6 and Figure 8 To facilitate the installation of the push screw 20, the outer circumferential surface of the second folding roller 2 is provided with mounting grooves 22 corresponding to the receiving grooves 23. Each mounting groove 22 is connected to each receiving groove 23, and one end of the bolt head of the push screw 20 is located in the mounting groove 22. In addition, in this embodiment, the push teeth 15, the push elastic component, the receiving grooves 23, and the mounting grooves 22 are all evenly distributed in multiple sets along the axial direction of the second folding roller 2. Each set of push teeth 15 is respectively provided in correspondence with each material clamping tooth 4 of the first folding roller 1. This ensures the uniformity of force when the paper is pushed, and allows maintenance or replacement of one push tooth 15 when it wears out, reducing subsequent maintenance costs. At the same time, it makes the installation of the push teeth 15 less likely to occupy the installation space at the end of the second folding roller 2, improving the applicability of the installation.

[0055] The implementation principle of Embodiment 2 of this application is the same as that of Embodiment 1. The main difference is that in this embodiment, the continuous cooperation of the first folding roller 1 and the second folding roller 2 with two identical structures can sequentially achieve folding at different positions on both sides of the conveying paper, thereby facilitating adaptation to different folding conditions required for conveying paper and making it highly applicable. In addition, in this embodiment, it is easy to disassemble a single push tooth 15 for maintenance or replacement, resulting in lower maintenance costs and making it easier to install the push tooth 15 without occupying the installation space at the end of the second folding roller 2, thus making it more applicable to installation.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
