Description

Technical Field

[0001] This application relates to the field of folding devices, and in particular to a fully automatic folding device. Background Technology

[0002] Wet wipes are portable cleaning products made of non-woven fabric or biodegradable materials that are pre-soaked in liquids (such as water, disinfectant, skin care ingredients, etc.). They are convenient to use and discard, and are widely used in daily life, medical care, infant care, and other fields.

[0003] During the production and processing of wet wipes, they usually need to be cut and then folded by folding rollers. The cutting of wet wipes is mainly achieved by rotating the cutting roller and the auxiliary cutting roller mounted on the frame. Then, the cutting blade of the cutting roller and the cutting bottom blade of the auxiliary cutting roller work together to cut the wet wipes.

[0004] The position of wet wipes during the production process is easily affected by external forces and may shift, making it difficult to ensure the cutting quality of wet wipes after cutting. Utility Model Content

[0005] In order to ensure the stability of the wet wipes during cutting, and thus ensure the cutting quality of the wet wipes after cutting, this application provides a fully automatic folding device.

[0006] The fully automatic folding device provided in this application adopts the following technical solution: A fully automatic folding device includes a frame, a cutting roller, and a cutting auxiliary roller. The cutting roller and the cutting auxiliary roller are rotatably mounted on the frame. The cutting roller is fixedly equipped with cutting blades. Multiple sets of cutting blades are distributed circumferentially around the axis of the cutting roller. The cutting auxiliary roller is provided with cutting bottom blades that correspond one-to-one with each set of cutting blades. The cutting auxiliary roller is provided with multiple sets of suction holes distributed circumferentially around its own axis. Each set of suction holes corresponds one-to-one with the cutting bottom blades and is located close to each cutting bottom blade.

[0007] By adopting the above technical solution, when the wet wipes are fed between the cutting roller and the cutting auxiliary roller during the production process, the suction holes are drawn in by the action of a fan or vacuum pump, thereby creating a continuous negative pressure at the suction holes. This achieves the adsorption treatment of the cut paper towels, which helps to ensure the stability of the wet wipes during cutting. It also makes it less likely that the position of the wet wipes will shift due to external forces during cutting, thus ensuring the cutting quality of the wet wipes after cutting.

[0008] Optionally, the cutting roller and the cutting auxiliary roller are vertically distributed, the cutting auxiliary roller is located at the bottom of the cutting roller, and each group of suction holes is provided with two rows, with multiple suction holes evenly distributed along the axial direction of the cutting auxiliary roller in each row.

[0009] By adopting the above technical solution, the cutting auxiliary roller at the bottom can more stably support the wet wipes, while the setting of two rows of suction holes expands the adsorption coverage area, which helps to improve the uniformity of force when the wet wipes are adsorbed and fixed, and further ensures the stability of the wet wipes during adsorption and fixation.

[0010] Optionally, the cutting auxiliary roller has suction communication holes extending along its own axis. Multiple suction communication holes are provided corresponding to each group of suction holes, and each group of suction holes is connected to each suction communication hole.

[0011] By adopting the above technical solution, it is convenient to directly achieve air intake treatment of each group of air intake holes through the air intake connection hole, without the need to drive each air intake hole separately, which is convenient and stable.

[0012] Optionally, it also includes a clamping roller rotatably mounted on the frame. The cutting auxiliary roller and the clamping roller are distributed in a horizontal direction. The outer circumferential surface of the cutting auxiliary roller is provided with a plurality of cloth-feeding grooves evenly distributed around its own axis. The cloth-feeding grooves are provided in a one-to-one correspondence with the cutting bottom knife. Each set of suction holes is located between each cloth-feeding groove and the cutting bottom knife. Each cloth-feeding groove is provided with a cloth-feeding knife. The clamping roller is provided with a plurality of clamping grooves evenly distributed around its own axis. The clamping grooves are provided in a one-to-one correspondence with the cloth-feeding knives. Each clamping groove is provided with a cloth-feeding knife. When one of the cloth-feeding knives rotates into the clamping groove, the cloth-feeding knife is located at the top of the clamping knife.

[0013] By adopting the above technical solution, during the rotation of the cutting auxiliary roller and the clamping roller, the cooperation of the cloth-inserting knife and the clamping groove facilitates the initial folding of the paper towel during feeding. Furthermore, the wet towel is still adsorbed and fixed through the suction hole during the initial folding process, which helps to ensure the stability of the wet towel during the initial folding while ensuring the stability of the wet towel during cutting.

[0014] Optionally, the bottom of the fabric clamping roller is provided with a conveying guide plate for guiding the folded wet wipes, and the conveying guide plate is arc-shaped.

[0015] By adopting the above technical solution, the wet wipes after the first fold are guided by the conveyor guide plate, which helps to further ensure the conveying stability of the wet wipes after the first fold.

[0016] Optionally, the frame is further provided with a feeding mechanism, which includes a feeding roller, two feeding guide rollers and a spraying assembly. The feeding roller and the two feeding guide rollers are rotatably mounted on the frame. The two feeding guide rollers are located at the bottom of the feeding roller and distributed in a horizontal direction. The spraying assembly includes a spray pipe for spraying the paper towel, and the spray pipe is located between the two feeding guide rollers.

[0017] By adopting the above technical solution, during the production and processing of wet wipes, the wipes are conveyed sequentially around the feed roller and the two feed guide rollers. The spray pipe located between the two feed guide rollers can spray the wet wipes before they are cut, which helps to reduce the evaporation of the wet wipe liquid and ensure the service life of the wet wipes.

[0018] Optionally, the frame is also provided with a collection box, which has an opening at the top and is located at the bottom of the spray pipe.

[0019] By adopting the above technical solution, the collection box facilitates the centralized collection of spray liquid in the spray pipe and the unified treatment of dripping spray liquid.

[0020] Optionally, two collection guide plates are installed on the top of the collection box, and the two collection guide plates are respectively located close to both sides of the collection box in the width direction and are inclined.

[0021] By adopting the above technical solution, the setting of the collection guide plate plays a further guiding role in collecting and guiding the dripping liquid, making it less likely for the sprayed liquid to drip outside the collection box.

[0022] Optionally, the feeding mechanism further includes two feeding tension rollers, which are vertically distributed and located between the feeding guide roller and the cutting roller.

[0023] By adopting the above technical solution, the wet wipes are sequentially arranged around the feed roller, the bottom of the two feed guide rollers, between the two feed tension rollers, and between the cutting roller and the cutting auxiliary roller during the conveying process. The feed tension roller plays a tensioning role during the conveying of the wet wipes, which helps to ensure the stability of the wet wipes when they are fed into the cutting roller and the cutting auxiliary roller for cutting.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a fan or vacuum pump to draw air through the suction holes, a continuous negative pressure is generated at the suction holes, which in turn adsorbs the paper towels during cutting. This helps to ensure the stability of the wet wipes during cutting, making it less likely for the wet wipes to shift due to external forces, and thus ensuring the quality of the cut.

[0025] 2. The design of two rows of suction holes expands the adsorption coverage area, which helps to improve the uniformity of force during the adsorption and fixation of wet wipes, and further ensures the stability of the wet wipes during adsorption and fixation.

[0026] 3. The combination of the cloth-inserting knife and the cloth-clamping groove facilitates the initial folding of the paper towel during feeding. During the initial folding of the wet towel, it is still adsorbed and fixed by the suction hole, which helps to ensure the stability of the wet towel during the initial folding while ensuring the stability of the wet towel during cutting.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a fully automatic folding device. (Refer to...) Figure 1 The fully automatic folding device includes a frame 1, a feeding mechanism, a cutting mechanism and a folding mechanism. In this embodiment, the feeding mechanism, the cutting mechanism and the folding mechanism are each provided in two sets and are respectively located near the two sides of the frame 1.

[0035] Reference Figure 2 and Figure 3The feeding mechanism includes a feeding roller 2, two feeding guide rollers 3, a spraying assembly, and two feeding tension rollers 4. The feeding roller 2, two feeding guide rollers 3, and two feeding tension rollers 4 are all rotatably mounted on the frame 1. The two feeding guide rollers 3 are located at the bottom of the feeding roller 2 and are distributed horizontally. The spraying assembly includes a spray feeding pipe 5 and a spray pipe 6. One end of the spray feeding pipe 5 is connected to an external spray liquid source, and the other end is connected to one end of the spray pipe 6. The spray pipe 6 is horizontally positioned between the two feeding guide rollers 3. The bottom of the spray pipe 6 has multiple spray holes (not shown in the figure) evenly distributed along its own axis to spray the conveyed paper towels, reducing the evaporation of liquid during cutting and folding, and ensuring the lifespan of the paper towels.

[0036] Reference Figure 3 To facilitate the centralized collection of spray liquid within the spray pipe 6, a collection box 7 is fixedly installed on the frame 1. The collection box 7 is located at the bottom of the spray pipe 6 and has an open top to facilitate the unified treatment of dripping spray liquid. In addition, two collection guide plates 8 are installed on the top of the collection box 7. The two collection guide plates 8 are located on both sides of the width direction of the collection box 7, and the two collection guide plates 8 are inclined from top to bottom in a direction that gradually approaches each other to further guide the dripping liquid, so that the spray liquid is less likely to drip outside the collection box 7.

[0037] Continue to refer to Figure 3 Two feed tension rollers 4 are vertically distributed. When the wet wipes are conveyed, they are sequentially arranged around the bottom of the feed rollers 2, the two feed guide rollers 3, and between the two feed tension rollers 4, and are fed into the cutting mechanism through the feed tension rollers 4 at the bottom. The feed tension rollers 4 play a tensioning role when the wet wipes are conveyed, which helps to ensure the stability of the wet wipes when they are fed into the cutting mechanism for cutting.

[0038] Reference Figure 2 and Figure 3 The cutting mechanism includes a cutting roller 9 and a cutting auxiliary roller 10. Both the cutting roller 9 and the cutting auxiliary roller 10 are rotatably mounted on the frame 1 and are staggered vertically from top to bottom. The cutting roller 9 and the cutting auxiliary roller 10 are located on the side of the feed tension roller 4 that is away from the feed guide roller 3 in the horizontal direction. During the cutting process of wet wipes, they are tensioned by the two feed tension rollers 4 and then fed between the cutting roller 9 and the cutting auxiliary roller 10.

[0039] Reference Figure 3 A cutting blade 11 is fixedly mounted on the outer circumferential surface of the cutting roller 9. Multiple sets of cutting blades 11 are evenly distributed around the axis of the cutting roller 9. In this embodiment, four sets of cutting blades 11 are selected. Four sets of cutting bottom blades 12, corresponding one-to-one with each set of cutting blades 11, are provided on the outer circumferential surface of the cutting auxiliary roller 10. When the wet wipe is fed to the cutting blades 11 and the cutting bottom blades 12, the wet wipe is cut through the cooperative action of the cutting blades 11 and the cutting bottom blades 12.

[0040] Reference Figure 3 and Figure 4 In this embodiment, the cutting auxiliary roller 10 is provided with four sets of suction holes 13 circumferentially distributed around its own axis. Each set of suction holes 13 corresponds one-to-one with each cutting bottom blade 12. In this embodiment, each set of suction holes 13 is arranged in two parallel rows, and each set of two rows of suction holes 13 is located close to each cutting bottom blade 12. Multiple suction holes 13 are evenly distributed along the axial direction of the cutting auxiliary roller 10 in each row. By the action of a fan or vacuum pump, air is drawn into each suction hole 13, thereby generating a continuous negative pressure at the suction hole 13. This allows for the adsorption treatment of the cut paper towel through the suction hole 13, which helps to ensure the stability of the wet towel during cutting.

[0041] Reference Figure 3 The cutting auxiliary roller 10 has suction communication holes 14 extending along its own axis. Multiple suction communication holes 14 are provided corresponding to the two rows of suction holes 13 in each group. Each group of suction holes 13 is connected to each suction communication hole 14, so that the suction treatment of each group of two rows of suction holes 13 can be directly realized through a single suction communication hole 14, without the need to drive each suction hole 13 separately, which is convenient and stable.

[0042] Reference Figure 2 and Figure 3 The folding mechanism includes a clamping roller 15 and a folding roller 16. The cutting auxiliary roller 10 and the clamping roller 15 are distributed horizontally, with the clamping roller 15 located on the side of the cutting auxiliary roller 10 away from the feeding tension roller 4. The clamping roller 15 and the folding roller 16 are staggered vertically from top to bottom, with the folding roller 16 located on the side of the clamping roller 15 away from the cutting auxiliary roller 10. The outer circumferential surface of the cutting auxiliary roller 10 has multiple uniformly distributed circumferentially distributed fabric-feeding grooves 17 around its own axis. In this embodiment, four fabric-feeding grooves 17 are provided, and each fabric-feeding groove 17 is equipped with a fabric-feeding knife 18.

[0043] Reference Figure 3 and Figure 5 Each cloth-inserting groove 17 corresponds one-to-one with each cutting bottom knife 12, and four sets of suction holes 13 are located between each cloth-inserting groove 17 and the cutting bottom knife 12. The cloth-clamping roller 15 has multiple cloth-clamping grooves 19 evenly distributed around its own axis. In this embodiment, four cloth-clamping grooves 19 are provided and correspond one-to-one with the cloth-inserting knife 18. Each cloth-clamping groove 19 is equipped with a cloth-clamping knife 20. When one of the cloth-inserting knives 18 rotates into the cloth-clamping groove 19, the cloth-inserting knife 18 is located at the top of the cloth-clamping knife 20, so that the initial folding of the paper towel can be achieved through the cooperation of the cloth-inserting knife 18 and the cloth-clamping groove 19. During the initial folding of the wet towel, it is still adsorbed and fixed by the suction holes 13, which has strong stability.

[0044] Reference Figure 5To ensure the stability of the position of the wet wipe when it is fed into the clamping groove 19, the clamping roller 15 is provided with a feeding rotation assembly that drives the feeding knife 18 to rotate. Specifically, the feeding rotation assembly includes a feeding fixing seat 21, a feeding rotating seat 22, a feeding spring 23, a feeding rotating rod 24, a feeding connecting rod 25, and a feeding drive seat 26. The feeding fixing seat 21 is fixedly installed on the frame, and the feeding rotating seat 22 is fixedly installed on one end of the lower folding roller 16 and rotatably installed on the feeding fixing seat 21.

[0045] Continue to refer to Figure 5 The fabric clamping knife 20 is fixedly installed on the fabric inserting rotating rod 24. The fabric inserting rotating rod 24 passes through and is rotatably installed on the fabric inserting rotating seat 22. The fabric inserting connecting rod 25 is fixedly installed on the fabric inserting rotating rod 24. One end of the fabric inserting spring 23 is connected to the fabric inserting connecting rod 25, and the other end is connected to the fabric inserting rotating seat 22. The fabric inserting drive seat 26 is located at the end of the fabric inserting connecting rod 25 away from the fabric inserting spring 23. The fabric inserting rotating rod 24 is located between the fabric inserting spring 23 and the fabric inserting drive seat 26, so that the fabric inserting drive seat 26 moves towards the fabric inserting fixed seat 21 under the elastic force of the fabric inserting spring 23. To ensure the stability of the elastic force applied by the fabric inserting spring 23 to the fabric inserting drive seat 26, a fabric inserting guide rod 27 is fixedly installed on the fabric inserting connecting rod 25. The fabric inserting spring 23 is sleeved on the fabric inserting guide rod 27, so that the fabric inserting guide rod 27 plays a certain limiting role for the fabric inserting spring 23.

[0046] Continue to refer to Figure 5 The feeding drive seat 26 has a rotatably mounted drive roller 28, which abuts against and rolls against the feeding fixing seat 21 under the elastic force of the feeding spring 23. The feeding fixing seat 21 is provided with a feeding guide groove 29 corresponding to the drive roller 28. When the feeding drive seat 26 rotates to the position of the feeding guide groove 29, the feeding drive seat 26 drives the feeding connecting rod 25 to rotate, which in turn drives the feeding rotating rod 24 and the clamping knife 20 in one of the clamping grooves 19 to rotate together, so that the clamping knife 20 can stably clamp the wet wipes located in the clamping groove 19 by pressing. When the feeding drive seat 26 disengages from the feeding guide groove 29, the clamping knife 20 in the clamping groove 19 releases the restriction on the wet wipes in the clamping groove 19, so that the wet wipes can be sent to the next station.

[0047] Reference Figure 3 and Figure 5 A conveyor guide plate 30 is fixedly installed on the frame 1. The conveyor guide plate 30 is arc-shaped and located at the bottom of the clamping roller 15. One end of the conveyor guide plate 30 is positioned between the clamping roller 15 and the folding roller 16 to guide the initially folded wet wipes and facilitate their conveying between the clamping roller 15 and the folding roller 16. The folding rollers 16 of the two folding mechanisms are adjacent and distributed horizontally. The initially folded wet wipes are finally fed between the two folding rollers 16 of the two folding mechanisms for folding and conveying.

[0048] The implementation principle of the fully automatic folding device in this application embodiment is as follows: when the wet wipes are fed between the cutting roller 9 and the cutting auxiliary roller 10 during the production process, the suction holes 13 are drawn in by the action of the fan or vacuum pump, thereby generating a continuous negative pressure at the suction holes 13, which facilitates the adsorption treatment of the cut paper wipes, helps to ensure the stability of the wet wipes during cutting, and makes the position of the wet wipes during cutting less susceptible to displacement due to external forces, thus ensuring the cutting quality of the wet wipes after cutting.

[0049] 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.
