Description

Technical Field

[0001] This utility model relates to the field of textile post-processing technology, specifically to a webbing flattening device. Background Technology

[0002] In the textile, apparel, bag, and auto parts industries, webbing, as an important type of ribbon fabric, requires maintaining its flatness during production and subsequent processing to ensure product quality. After weaving, webbing is prone to wrinkles, curling, and edge lifting due to the characteristics of the weaving process, uneven winding tension, or storage environment. If it proceeds directly to subsequent processing stages, wrinkles can lead to distorted printed patterns, dimensional errors in cutting, uneven coating thickness, and even affect the structural strength or appearance quality of the final product. Therefore, webbing flattening is an indispensable part of the production chain.

[0003] According to Chinese patent document CN221566555U, a webbing flattening device relates to webbing production equipment, including a support frame and a conveyor belt installed above the support frame. A housing is mounted on the support frame, and the conveyor belt passes through the housing. The housing contains an atomizing chamber, a hot pressing chamber, a cold pressing chamber, and a cooling chamber. An atomizing nozzle connected to an external water source is installed in the atomizing chamber. A hot rolling flattening assembly is installed in the hot pressing chamber, a cold rolling flattening assembly is installed in the cold pressing chamber, and a cold air inlet connector connected to an external cold air blower is installed in the cooling chamber. This invention can flatten raised or recessed areas on the webbing, improving the flatness of the webbing; and the flattened webbing returns to room temperature, effectively preventing overheating and its impact on subsequent packing processes.

[0004] The above-mentioned device also has the problem that if the webbing is not taut when it is laid out, there may be excessive jumping during the conveying process, and the shaping effect after laying out is not good, and the flatness cannot be guaranteed to last. Utility Model Content

[0005] This invention reduces jumping and deviation during the conveying process by setting up conveying rollers and extrusion rollers. The heating wire set in the hot pressing roller can reduce mechanical flattening resistance and improve the pleat unfolding efficiency. The cold pressing roller absorbs residual heat through water circulation to prevent thermal deformation and rebound, ensuring long-lasting flatness. The height of the hot pressing roller and the cold pressing roller is adjustable to adapt to webbing of different thicknesses, expand the applicable range of the equipment, and reduce changeover and adjustment time.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A webbing flattening device includes a support plate, a conveying component for conveying webbing is provided at the front of the surface of the support plate, a flattening component for flattening the webbing is provided at the middle of the surface of the support plate, and a winding bracket for retracting the flattened webbing is provided at the rear of the surface of the support plate. A belt for transmission is provided between the conveying component and the flattening component.

[0008] Preferably, the conveying assembly includes two conveying supports, each with a groove inside. A conveying roller is rotatably connected between the two conveying supports via a rotating shaft. A squeezing roller is slidably connected between the conveying supports.

A transition roller for changing the conveying direction of the webbing is rotatably connected between the conveying supports below the conveying roller.

[0009] Preferably, the flattening assembly includes two flattening supports, with support rollers for flattening the webbing rotatably connected to both ends of the two flattening supports. A rotary motor is fixedly connected to the outer wall of each flattening support. One end of one of the support rollers extends through the outside of the flattening support and is fixedly connected to the output end of the rotary motor. Belts are installed on the other ends of both support rollers extending through the outside of the flattening support. A hot pressing roller for hot pressing the webbing is installed above one of the support rollers, and a cold pressing roller for cold pressing the webbing is installed above the other support roller. A transition support is rotatably connected to the outside of the hot pressing roller and the cold pressing roller via a rotating shaft.

[0014] 1. This utility model can reduce jumping and deviation during the conveying process by setting the conveying roller and the squeezing roller, providing a stable foundation for subsequent flattening.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1As shown, this utility model provides a webbing flattening device, including a support plate 1. A conveying component 2 for conveying the webbing is disposed at the front of the support plate 1, a flattening component 3 for flattening the webbing is disposed at the middle of the support plate 1, and a winding bracket 4 for retracting the flattened webbing is disposed at the rear of the support plate 1. A belt 5 for transmission is disposed between the conveying component 2 and the flattening component 3. The conveying component 2 conveys the webbing to be flattened to the flattening component 3 for flattening. The flattened webbing is then rolled up and collected by the winding bracket 4. The flattened webbing can be automatically collected, reducing manual labor. The belt 5 is a synchronous gear belt to ensure that the conveying speed of the conveying component 2 is consistent with the feeding speed of the flattening component 3, avoiding wrinkling of the webbing and unsatisfactory flattening effect caused by inconsistent speeds.

[0023] like Figure 2 As shown, the conveying assembly 2 includes two conveying supports 21. The conveying supports 21 have grooves inside. The two conveying supports 21 are rotatably connected by a conveying roller 22 through a rotating shaft. A squeezing roller 23 is slidably connected between the conveying supports 21. Both ends of the squeezing roller 23 are rotatably connected to sliders 24. The sliders 24 are slidably connected in the groove. A telescopic electric telescopic rod 25 is fixedly connected to the outer wall of the slider 24. The end of the electric telescopic rod 25 away from the slider 24 is fixedly connected to the inner wall of the groove. A transition roller 26 for changing the conveying direction of the webbing is rotatably connected between the conveying supports 21 below the conveying roller 22. The webbing is passed between the conveyor roller 22 and the extrusion roller 23. The electric telescopic rod 25 pushes the slider 24 and the extrusion roller 23 closer to the conveyor roller 22, squeezing the webbing so that it is tightly attached to the surface of the conveyor roller 22. Then, the direction of webbing transport is changed by the transition roller 26, so that the webbing passes through the flattening component 3. When the winding speed of the winding bracket 4 is higher than the conveying speed, the webbing can be tightened to improve the flattening effect. A pressure sensor can be added between the conveyor component 2 and the winding bracket 4 to ensure that the elastic performance of the webbing will not be reduced due to excessive pressure.

[0024] By attaching the webbing tightly to the surface of the conveyor roller 22, excess bouncing of the webbing during conveying can be reduced, ensuring that the difference in left and right position of the webbing when it enters the leveling component 3 is not too large.

[0025] like Figure 3 and Figure 4As shown, the flattening assembly 3 includes two flattening brackets 31. Support rollers 32 for flattening the webbing are rotatably connected to both ends of the two flattening brackets 31. A rotary motor 33 is fixedly connected to the outer wall of the flattening bracket 31. One end of one support roller 32 extends through the outside of the flattening bracket 31 and is fixedly connected to the output end of the rotary motor 33. Belts 34 are installed on the other ends of both support rollers 32 extending through the outside of the flattening bracket 31. A hot pressing roller 36 for hot pressing the webbing is installed above one support roller 32, and a cold pressing roller 37 for cold pressing the webbing is installed above the other support roller 32. A transition bracket 42 is rotatably connected to the outside of the hot pressing roller 36 and the cold pressing roller 37 via a rotating shaft. Two telescopic brackets 35 for adjusting the height of the transition bracket 42 are fixedly connected to the outside of the transition bracket 42. The telescopic bracket 35 is fixedly connected to the surface of the support plate 1 at one end away from the transition bracket 42. The cold pressing roller 37 has a cavity inside. One end of the cold pressing roller 37 is fixedly connected to a water inlet pipe 38 that extends into the interior of the cold pressing roller 37. The other end of the cold pressing roller 37 is fixedly connected to a water return pipe 41 that extends into the interior of the cold pressing roller 37. A water storage tank 40 is fixedly connected to the surface of the transition bracket 42. A water pump 39 is fixedly connected to the surface of the transition bracket 42 near the water storage tank 40. The end of the water inlet pipe 38 away from the cold pressing roller 37 is fixedly connected to the outlet end of the water pump 39. The inlet end of the water pump 39 is fixedly connected to the water storage tank 40 through a pipe that extends into the interior of the water storage tank 40. The end of the water return pipe 41 away from the cold pressing roller 37 is fixedly connected to the water storage tank 40 that extends into the interior of the water storage tank 40. The webbing is passed sequentially between the first support roller and the hot pressure roller, and between the second support roller and the cold pressure roller. The telescopic bracket 35 controls the transition bracket 42, the hot pressure roller 36 and the cold pressure roller 37 to descend. Under the support of the support roller 32, a certain pressure is applied to the webbing. The hot pressure roller 36 heats the flattened position of the webbing. Heating can soften the material, reduce the mechanical force required for flattening, and at the same time reduce the wear of the hot pressure roller 36.

[0026] The water pump 39 transports water from the water storage tank 40 to the interior of the cold pressure roller 37 through the water inlet pipe 38, and finally flows back to the interior of the water storage tank 40 through the water return pipe 41. This can absorb the heat from the heating roller 36 on the webbing, restore the thermal deformation of the webbing, help the webbing to set its shape, and finally the winding bracket 4 rolls up the webbing for storage.

[0027] like Figure 5 As shown, the hot press roller 36 has an internal cavity, and a heating tube 361 for heating is installed inside the hot press roller 36. The heating tube 361 is electrically connected to an external power source via an electric wire. The heat generated by the electric current passing through the resistance wire inside the heating tube heats the inside of the hot press roller 36, and is finally conducted to the webbing, so that the webbing can be better shaped. At the same time, it can also accelerate the evaporation of moisture and avoid moisture residue causing secondary wrinkles.

[0028] A pressure sensor is installed inside the support roller 32. The pressure sensor measures the pressure applied by the hot pressure roller 36 and the cold pressure roller 37 to the webbing during the laying process. The pressure is adjusted by the telescopic bracket 35 to prevent the hot pressure roller 36 and the cold pressure roller 37 from applying too much pressure to the webbing during the laying process, which could cause damage to the webbing.

[0029] The winding support 4 includes a support and a rotatable winding roller. A winding motor is fixedly connected to the outside of the support. The output end of the winding motor is fixedly connected to the winding roller. The winding motor can control the winding speed of the webbing, control the tension of the webbing conveyor and flattening, eliminate loose wrinkles, avoid damage to the webbing shape, and ensure flattening uniformity.

[0030] The working principle of this utility model is as follows: the conveying component 2 conveys the webbing to the flattening component 3, and the webbing is flattened by the support roller 32, the hot pressing roller 36 and the cold pressing roller 37. The hot pressing roller 36 heats the webbing while pressing it flat through the heating tube 361, which can accelerate the evaporation of moisture and avoid moisture residue causing secondary wrinkles. Then, the cold pressing roller 37 cools the webbing through the internal flowing water, locks in the heat setting effect, prevents wrinkles from rebounding and avoids secondary deformation in subsequent processing. Finally, the webbing that has been hot and cold pressed is rolled up and stored by the winding bracket 4.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
