Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and in particular relates to an anti-rolling device for fabric processing. Background Technology

[0002] Fabric processing is a crucial process that transforms fibrous materials into finished fabrics, encompassing weaving, dyeing, printing, finishing, and cutting and sewing. Among these processes, anti-curling devices, by suppressing fabric edge warping, ensure the stability of high-speed sewing and automated cutting, and are widely used in apparel, home textiles, and industrial textile production, helping the industry transform towards efficiency, intelligence, and sustainability.

[0003] For example, a fabric winding device with an anti-curling edge device, as described in patent application number 202320706237.6, relies on a pressure roller pressing on the top of the fabric roll to keep the fabric surface flat and prevent curling edges during the winding process, thereby ensuring that the two ends of the fabric roll will not bulge after the fabric is wound into a roll.

[0004] However, the above patent has the following drawbacks: it only uses the pressure roller to press the fabric to prevent the edges from curling. However, if the pressure roller does not completely flatten the curled edges of the fabric, the subsequent winding of the fabric will affect the winding quality of the fabric, resulting in wrinkles after the fabric is wound up. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this utility model provides an anti-curling edge device for fabric processing. The problem it solves is that the fabric in the processing chamber is first straightened by two inclined blocks, which prevents the fabric with curled edges from being directly flattened without being straightened at the beginning, which would cause wrinkles in the fabric and thus fail to achieve a good curling edge treatment effect. By contacting the fabric with the pressure roller, the moving fabric can be subjected to a secondary edge pressing treatment, thereby further improving the effect of anti-curling edge treatment of the fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric processing anti-rolling device, comprising a material roller frame and a processing chamber, wherein the processing chamber is disposed on the material roller frame, the material roller frame is wound with fabric, and one end of the fabric passes through the processing chamber, and the processing chamber is provided with an edge rolling processing mechanism inside;

[0007] The edge-rolling mechanism includes at least two pre-treatment modules and at least two fabric pressing modules. The fabric feeding direction of the processing chamber is from the pre-treatment module to the fabric pressing module. The pre-treatment module includes inclined blocks, and the two inclined blocks form a figure-eight shape along the two ends of the fabric feeding direction.

[0008] Optionally, each of the pressing modules includes a pressure roller, a buffer plate, at least two springs, and a pressing module connecting plate. The pressure roller is located below the buffer plate, and both sides of the pressure roller are connected to the buffer plate via rotating shafts.

[0009] Optionally, the buffer plate is located below the fabric pressing module connecting plate, one end of each of the two springs is connected to the fabric pressing module connecting plate, and the other end of each of the two springs is connected to the buffer plate.

[0010] Optionally, a lateral adjustment mechanism is provided above each of the two pretreatment modules and the two pressing modules, and the lateral adjustment mechanism is connected to the pretreatment module and the two pressing modules respectively through connectors.

[0011] Optionally, the lateral adjustment mechanism includes at least two adjustment plates, each of which has a groove inside, and at least two sliders are slidably disposed in the groove. The two sliders are respectively connected to two inclined blocks and two fabric pressing module connecting plates via connecting rods.

[0012] Optionally, both sides of the two adjustment plates are provided with adjustment strips, which are connected to the adjustment plates via connecting rods.

[0013] Optionally, the adjusting bar is connected to the processing chamber, and an electric push rod is provided inside the adjusting bar. The push head of the electric push rod is connected to a connecting block, and one end of the connecting block is connected to the adjusting bar through a connecting rod.

[0014] Optionally, through slots are provided on both sides of the processing chamber, and a flat plate is provided inside the through slots, with both sides of the flat plate extending out of the processing chamber.

[0015] Optionally, both sides of the flat plate are curved downwards.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0017] This invention first uses two inclined blocks to smooth the fabric in the processing chamber, which avoids the fabric with rolled edges being pressed flat without being smoothed at the beginning, which would cause wrinkles in the fabric and thus fail to achieve a good rolled edge treatment effect.

[0018] This invention uses a pressure roller to contact the fabric, which allows for secondary edge pressing of the fabric, thereby further improving the effect of preventing the fabric from curling. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] refer to Figures 1 to 5 An anti-curling device for fabric processing includes a fabric roller frame 1 and a processing chamber 2, with one end of the fabric passing through the processing chamber 2. Through slots 21 are provided on both sides of the processing chamber, and a curling edge treatment mechanism 3 is provided inside the processing chamber 2. This mechanism prevents the fabric entering the processing chamber 2 from curling, thus reducing the risk of wrinkles caused by curling edges on the fabric roller frame 1 and affecting the quality of fabric processing.

[0027] It should be noted that the hem-rolling mechanism 3 includes at least two pre-treatment modules 31 and at least two fabric pressing modules 32. The fabric feeding direction of the processing chamber 2 is from the pre-treatment module 31 to the fabric pressing module 32. The two pre-treatment modules 31 are inclined blocks 311 with an inclination angle from the center to one side. Thus, the two pre-treatment modules 31 look like a "figure eight". When the fabric is being rolled up and moving, if the fabric has a rolled edge, the fabric will first contact the top of the pre-inclination block 311, and then move along the inclined edge until it is guided to the side of the fabric. This can achieve the effect of smoothing the fabric, thereby avoiding the method of directly using the pressure roller 321 to flatten the fabric, which cannot smooth the rolled edge of the fabric in advance. If the fabric with a rolled edge is not smoothed at the beginning and is directly flattened, the fabric will wrinkle, thus failing to achieve a good hem-rolling effect.

[0028] More importantly, the fabric pressing module 32 includes a pressure roller 321, a buffer plate 323, at least two springs 324, and a fabric pressing module connecting plate 325. The pressure roller 321 is rotatably connected to the bottom of the buffer plate 323 via a rotating shaft. By contacting the fabric with the pressure roller 321, a secondary edge pressing process can be performed on the moving fabric, thereby further improving the effect of preventing the fabric from curling. The fabric pressing module connecting plate 325 is connected to the top of the buffer plate 323 via multiple springs 324, so that when the pressure roller 321 moves downward and contacts the moving fabric, it can prevent large-scale edge curling. The downward force exerts a downward pressure on the fabric, further tightening it and preventing it from moving further. Therefore, the spring 324 is designed so that when the pressure roller 321 moves downward and contacts the fabric, the spring 324 contracts after the pressure roller 321 is subjected to downward pressure. At this time, the pressure roller 321 can obtain a small pre-travel distance that can move vertically. This allows the pressure roller 321 to move upward a small distance after contacting the fabric, effectively mitigating the impact force caused by the downward movement of the pressure roller 321 on the fabric and thus protecting the fabric.

[0029] refer to Figures 1 to 4 A fabric processing anti-rolling device is disclosed, comprising a lateral adjustment mechanism 4 above each of two pretreatment modules 31 and two pressing modules 32. The lateral adjustment mechanism 4 is connected to the pretreatment module 31 and the two pressing modules 32 respectively via connectors. The lateral adjustment mechanism 4 includes at least two adjustment plates 41, each with a groove inside. At least two sliders are slidably disposed within the groove. The sliders are connected to two inclined blocks 311 and two pressing module connecting plates 325 respectively via connecting rods. The sliders can adjust the lateral movement of the inclined blocks 311 and the pressing module connecting plates 325, thereby adjusting the distance between them. This allows the device to be used for fabrics of different widths. The device can be used by simply adjusting the distance between the two inclined blocks 311 and the two pressing module connecting plates 325 to the appropriate position for the fabric.

[0030] It should be noted that the inclined block 311 and the fabric pressing module connecting plate 325 slide in the groove of the adjusting plate 41 only by means of a slider. If the inclined block 311 and the fabric pressing module connecting plate 325 are touched, the position will be offset, and the fabric cannot be processed. In order to fix the slider when it is adjusted to a suitable position, the position of the slider can be fixed by magnetic attraction or any other means.

[0031] refer to Figure 1 and 2An anti-rolling device for fabric processing includes two adjusting plates 41 with adjusting strips 5 on both sides. An electric push rod is installed inside the adjusting strip 5. Connecting blocks are connected to both sides of the adjusting strip 5. The connecting blocks are connected to the connecting blocks inside the adjusting strip 5 through connecting rods. When the electric push rod is activated, the adjusting strip 5 can be raised through the connecting blocks, thereby achieving the effect of adjusting the height of the two pre-treatment modules 31 and the two pressing modules 32. The electric push rod is a small, high-precision push rod, used to make minor adjustments to the height of the pre-treatment modules 31 and the two pressing modules 32, mainly for processing fabrics of different thicknesses.

[0032] refer to Figure 4 An anti-rolling device for fabric processing is provided. To meet different fabric processing needs, the processing chamber 2 has through slots 21 on both sides. A flat plate 22 is connected to the bottom of the through slot 21. The flat plate 22 extends out of the processing chamber 2 on both sides, and the part extending out of the processing chamber 2 is a downward-bent arc. When the fabric enters the processing chamber 2, the fabric is on the flat plate. After being processed by the inclined block 311 and the pressure roller 321, the fabric is pulled by a downward force. If there is no downward-bent arc to protect the fabric, the fabric will be cut and damaged by the sharp edge of the through slot 21, thus affecting the quality of fabric processing.
