Description

Technical Field

[0001] This utility model relates to the field of fabric spreading equipment technology, and in particular to a fabric spreading device. Background Technology

[0002] In garment factories, fabric is laid flat on a cutting table using a fabric spreading machine for cutting. Fabric spreading requires a smooth surface, but existing fabric spreading machines, especially when spreading knitted fabrics, often cause wrinkles and curled edges due to the fabric's inherent characteristics. These wrinkles severely affect the quality of the fabric spreading process, and consequently, the quality of the garments.

[0003] Patent CN103303734B discloses a fabric spreading and spreading device for a fabric spreading machine. When the fabric is conveyed from left to right, the fabric rubs against the left and right fish fins on the spreading plate. Since the fish fins are distributed in an outward V-shape along the direction of fabric movement, the fabric is subjected to frictional force that spreads outward to both sides, thereby spreading the fabric surface and preventing wrinkles. At the same time, the left and right DC motors rotate, driving the left and right reverse toothed belts to roll from the middle to both sides. The teeth of the reverse toothed belts push the fabric edges to spread outward to both sides, thus preventing the edges from curling.

[0004] However, with the existing fabric-lifting devices, when the fabric is light, it tends to float up, which is not conducive to the fabric-lifting process. Therefore, there is an urgent need for a new fabric-lifting device. Utility Model Content

[0005] In view of the current situation of the technology, the present invention provides a fabric-pulling device, which can effectively solve the problem that when the fabric is light, it tends to float up, which is not conducive to the fabric-pulling work.

The second fabric-pulling belt group is used to pull the fabric in a horizontal direction and its pulling direction is the opposite of the first direction. The first and second fabric-pulling belt groups are used to simultaneously pull the fabric conveyed by the adsorption assembly to both sides to flatten the fabric.

The surface of the fabric-pulling roller is provided with a spiral first fabric-pulling rib and a second fabric-pulling rib, the spiral directions of the first fabric-pulling rib and the second fabric-pulling rib are opposite.

[0020] As a further description of the above technical solution:

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figures 1 to 6 The present invention provides a fabric-dispensing device, which includes a frame 1 and a first-stage fabric-dispensing unit 2.

[0040] The first-stage fabric spreading unit 2 includes an adsorption component 21 and a first fabric spreading component 22. The adsorption component 21 is disposed on the frame 1 to adsorb the fabric 600 conveyed to the adsorption component 21. The first fabric spreading component 22 is disposed on the frame 1 and located at the outlet of the adsorption component 21 to spread the fabric 600 conveyed by the adsorption component 21 to both sides to flatten the fabric 600.

[0041] The fabric-pulling device provided by this utility model, through the arrangement of components such as the frame 1 and the first-stage fabric-pulling unit 2, in practical applications, firstly conveys the fabric 600 to the adsorption component 21 for adsorption. During the conveying process, the fabric 600 can adhere to the adsorption component 21 for stable conveying, so that the fabric 600 will not float when passing through the first fabric-pulling component 22. Then, the first fabric-pulling component 22 can push the fabric 600 to both sides to flatten the fabric 600. By setting the adsorption component 21 and the first fabric-pulling component 22, this utility model makes it less likely for the fabric 600 to float when it is light, which is beneficial to the fabric-pulling operation.

[0042] Preferably, the adsorption component 21 is arranged at an angle, which allows the fabric 600 to adhere to the first fabric-pushing component 22 during the conveying process, making it easier to push the fabric 600 to both sides to flatten the fabric 600.

[0043] The fabric-pulling device further includes multiple winding rollers 5, which can wind the fabric 600 so that the fabric 600 can adhere to the adsorption component 21 for stable conveying during the conveying process. At the same time, the fabric 600 can also adhere to the first fabric-pulling component 22 during the conveying process, so that the first fabric-pulling component 22 can push the fabric 600 conveyed by the adsorption component 21 to both sides to flatten the fabric 600.

[0044] The adsorption component 21 may consist of a rectangular adsorption box and an air pump. The adsorption box has an internal air intake space and multiple adsorption holes on its surface. The air pump is connected to the air intake space to provide adsorption force.

[0045] To stably move the fabric 600 to both sides, the first fabric-moving assembly 22 includes a first fabric-moving belt group 221 and a second fabric-moving belt group 222. Both the first and second fabric-moving belt groups 221 and 222 are mounted on the frame 1 and are located on the same horizontal plane. The first fabric-moving belt group 221 is used to move the fabric 600 horizontally in a first direction, and the second fabric-moving belt group 222 is used to move the fabric 600 horizontally in the opposite direction to the first direction. The first and second fabric-moving belt groups 221 and 222 simultaneously move the fabric 600 conveyed by the adsorption assembly 21 to both sides to flatten the fabric 600. The first fabric-moving belt group 221 includes a first driving member and a first belt mounted on the frame 1. The first driving member drives the first belt to move, causing the fabric 600 to undulate along the first direction. The second fabric guide belt assembly 222 includes a second driving member and a second guide belt, both disposed on the frame 1. The second driving member drives the second guide belt to move, causing the fabric 600 to undulate in the opposite direction to the first direction. By configuring the first driving member, the first guide belt, the second driving member, and the second guide belt, the fabric 600 conveyed by the adsorption assembly 21 can be simultaneously moved to both sides to flatten the fabric 600, facilitating practical use.

[0046] To improve the flattening effect of the fabric 600, the fabric spreading device further includes a second-stage fabric spreading unit 3. The second-stage fabric spreading unit 3 is located on the frame 1 and corresponds to the feed inlet of the first-stage fabric spreading unit 2. The second-stage fabric spreading unit 3 is used to push the passing fabric 600 to both sides so that the pushed fabric 600 can be pushed to both sides again after entering the first-stage fabric spreading unit 2. The second-stage fabric spreading unit 3 includes a spreading roller 31 and a spreading plate 32 located on the frame 1. A first spreading space 310 for pushing the fabric 600 to both sides is formed between the spreading roller 31 and the spreading plate 32. The surface of the spreading roller 31 is provided with a spiral first spreading rib 311 and a second spreading rib 312, with the spiral directions of the first spreading rib 311 and the second spreading rib 312 being opposite. The first fabric-pulling rib 311 and the second fabric-pulling rib 312 have the same length along the axial direction of the fabric-pulling roller 31, and are symmetrically distributed with respect to the central radial section of the fabric-pulling roller 31. By setting the fabric-pulling roller 31 and the spreading plate 32, and by providing the first fabric-pulling rib 311 and the second fabric-pulling rib 312 in a spiral shape on the surface of the fabric-pulling roller 31, with the spiral directions of the first fabric-pulling rib 311 and the second fabric-pulling rib 312 being opposite, the fabric-pulling effect is improved. Therefore, by setting the first-stage fabric-pulling unit 2 and the second-stage fabric-pulling unit 3, the fabric 600 can be pulled twice, which can improve the flattening effect of the fabric 600.

[0047] To further improve the flattening effect of the fabric 600, the fabric spreading device also includes a third-stage fabric spreading unit 4. The third-stage fabric spreading unit 4 includes a conveying roller 41 and a pressing roller 42 disposed on the frame 1. A second fabric spreading space 410 is formed between the conveying roller 41 and the pressing roller 42 for spreading the fabric 600 along the conveying direction. The pressing roller 42 presses against the conveying roller 41, and their central axes are parallel. The conveying roller 41 drives the pressing roller 42 to rotate synchronously, so as to spread the fabric 600 along the conveying direction. A fabric spreading sleeve 411 is provided on the cylindrical surface of the conveying roller 41 corresponding to the second fabric spreading space 410. The fabric spreading sleeve 411 is made of fusible fabric. By setting the conveying roller 41 and the pressing roller 42, and providing a fabric-pulling sleeve 411 on the cylindrical surface corresponding to the conveying roller 41 and the second fabric-pulling space 410, the fabric-pulling sleeve 411 is made of diving cloth material. This design can stably convey the fabric 600 and prevent the fabric 600 from wrinkling due to slippage. Therefore, by setting the first-stage fabric-pulling unit 2, the second-stage fabric-pulling unit 3 and the third-stage fabric-pulling unit 4, the fabric 600 can be pulled three times, which can improve the flattening effect of the fabric 600.

[0048] The pressing roller 42 can be pressed against the conveying roller 41 by a torsion spring.

[0049] To improve the flattening effect of the fabric, multiple sets of the first fabric spreading components 22 can be provided. Some of the first fabric spreading components 22 are located at the inlet of the adsorption component 21, and others are located at the outlet of the adsorption component 21. This design can flatten the fabric 600 better and improve the flattening effect of the fabric spreading.

[0050] Working principle: First, the fabric 600 is conveyed to the adsorption component 21 for adsorption. During the conveying process, the fabric 600 can adhere to the adsorption component 21 and be conveyed stably, so that the fabric 600 will not float when passing through the first fabric spreading component 22. Then, the first fabric spreading component 22 can spread the fabric 600 to both sides to flatten the fabric 600.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
