Description

Technical Field

[0001] The present application relates to the technical field of non-woven fabric product manufacturing, and in particular to a folding device for producing non-woven fabric bibs. Background Art

[0002] Non-woven fabrics are also called non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc. They are made of polyester fiber and polyester fiber and are made through a needle-punching process. They can be made into different thicknesses, feels, hardness, etc. Non-woven fabrics are moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and tasteless, inexpensive, and recyclable. They can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical, filling materials, etc.

[0003] When non-woven fabrics are used to make bibs, they need to undergo multiple processing, and their edges usually need to be folded and hot-melt fixed to improve the appearance and durability after processing. Existing non-woven fabric production lines are usually specialized, that is, each part of the production line serves one or several similar products, and it cannot be applied to products with large differences. Therefore, the production line usually needs to be equipped with a variety of molds for combination in subsequent production, which increases the cost investment of the production line. The same is true for the folding structure of the non-woven fabric. Therefore, in order to solve the above problems, the present application provides a folding device for the production of non-woven bibs.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0008] Preferably, the folding sheet includes a lower shoveling section, a folding section and a lower pressing section, the initial position of the lower shoveling section and the final position of the lower pressing section are both horizontally arranged, the middle position of the folding section is vertically arranged, and there is a smooth transition arrangement among the lower shoveling section, the folding section and the lower pressing section.

[0009] Preferably, brackets are welded to both ends of the bottom plate, and a fixing rod is fixedly connected by bolts at the middle position between the two brackets.

[0010] Preferably, a first adjusting rod and a second adjusting rod are respectively welded on the two limiting plates. The first adjusting rod and the second adjusting rod are both slidably embedded on the fixing rod and fixed by fastening knobs.

[0011] Preferably, the folding piece is welded to the limiting plate through a connecting rod.

[0012] Preferably, the front view of the steam mechanism is in a U-shaped structure. A water delivery pipe communicating with its interior is fixedly connected to the top of the steam mechanism, and steam outlet holes are arranged inside the steam mechanism.

[0013] In summary, the present application includes the following beneficial technical effects:

Detailed Embodiment

[0021] The following is a further detailed description of the present application in combination with the attached Figure 1 - Figure 4 drawings.

[0022] Embodiment 1:

[0023] Reference Figure 1 - Figure 4 A folding device for producing non-woven bibs comprises an input roller 1 and an output roller 2 for pulling the non-woven fabric, a bottom plate 3 is arranged between the input roller 1 and the output roller 2, and two limit plates 6 are movably connected to the bottom plate 3 along the axial direction of the input roller 1, and folding sheets 7 are arranged on the opposite outer sides of the two limit plates 6, and the folding sheets 7 will turn the non-woven fabric passing thereon by 180 degrees, and the folding sheets 7 comprise a lower shovel section 71, a folding section 72 and a lower pressing section 73, the initial position of the lower shovel section 71 and the end position of the lower pressing section 73 are both horizontally arranged, the middle position of the folding section 72 is vertically arranged, and the lower shovel section 71, the folding section 72 and the lower pressing section 73 are smoothly transitionally arranged, and the initial position of the lower shovel section 71 is used to turn the non-woven fabric The non-woven fabric is shoveled up and separated from the bottom plate 3. The edge of the non-woven fabric is then displaced along the lower shoveling section 71 to the folding section 72. At this time, the edge of the non-woven fabric is in a vertical state. When it moves backward, the non-woven fabric reaches the position of the lower pressing section 73. At this time, the non-woven fabric is attached to the bottom wall of the groove 61 of the limiting plate 6. The non-woven fabric is flipped 180° at this time. The setting of the groove 61 makes the crease between the two sections narrower when the non-woven fabric is folded 180°, which is convenient for subsequent hot pressing. When the non-woven fabric is further transported forward, it will pass through the inner side of the steam mechanism 10. The folding sheet 7 is welded to the limiting plate 6 by a connecting rod, so as to ensure the stability of the position between the folding sheet 7 and the limiting plate 6, ensure that it can be synchronously displaced with the limiting plate 6, and improve the convenience of adjustment.

[0024] Brackets 4 are welded to both ends of the bottom plate 3, and a fixing rod 5 is bolted to the middle position of the two brackets 4. The combination of the brackets 4 and the fixing rod 5 forms an H-shaped structure in top view, and the bracket 4 is a door-shaped structure. Both sides of the bracket 4 are welded to both sides of the bottom plate 3, and an adjusting rod 1 8 and an adjusting rod 2 9 are welded to the two limit plates 6 respectively. The adjusting rod 1 8 and the adjusting rod 2 9 are slidably embedded in the fixing rod 5 and fixed by tightening knobs. The adjusting rod 1 8 and the adjusting rod 2 9 are staggered and do not interfere with each other. Each set of adjusting rods 1 8 and adjusting rods 2 9 is respectively provided with at least two, so as to ensure the stability of the position of the limit plates 6. The clearance between the limit plates 6 and the bottom plate 3 is matched for the passage of non-woven fabrics. At the same time, the two bottom plates 3 also have the effect of smoothing the non-woven fabrics.

[0025] The end of the limit plate 6 is also provided with a steam mechanism 10 for ironing and shaping the non-woven fabric. The front view of the steam mechanism 10 is in a U-shaped structure. Its top is fixedly connected with a water delivery pipe 11 communicated with its interior. And steam outlet holes 12 are arranged on the inner side of the steam mechanism 10. A heating structure is arranged on the inner side of the steam mechanism 10 to evaporate the water flow conveyed by the water delivery pipe 11 into water vapor, and then output through the outlet holes 12. The output steam will shape the non-woven fabric that has completed folding inside it. The shaped non-woven fabric is conveyed to the outside through the output roller 2 and will be hot melt bonded in the subsequent process. Thus, the folding operation of the non-woven fabric is completed.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
