Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a hot-pressing forming fabric anti-crease stretching device. Background Technique

[0002] In the textile and fabric processing industries, the hot-pressing forming technology is widely used to manufacture fabric products with specific shapes and textures. After the fabric is completed, it often needs to be processed in various ways, and stretching processing is one of the operations. However, when the existing fabric stretching equipment is used, the following problems still exist:

[0003] During the hot-pressing forming process, the fabric is prone to creases due to the action of high temperature and pressure, and during the conveying process, the fabric is also prone to wrinkles. If the wrinkles in the fabric are not fully flattened before subsequent processing, it will directly affect the subsequent stretching processing effect, easily resulting in problems such as uneven stretching and fabric deformation. This not only affects the appearance quality of the product but also may reduce its durability and market value.

[0004] In view of the above problems, the present utility model document proposes a hot-pressing forming fabric anti-crease stretching device. Content of the Utility Model

[0005] The purpose of the present utility model is to solve the disadvantages in the prior art that wrinkles easily appear during fabric processing and conveying, and the existence of wrinkles is not conducive to the subsequent stretching of the fabric, and a hot-pressing forming fabric anti-crease stretching device is proposed.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] A hot-pressing forming fabric anti-crease stretching device, comprising:

[0008] A housing, inside which two first conveying rollers, two limiting rollers and two second conveying rollers are rotatably connected. The two first conveying rollers, the two limiting rollers and the two second conveying rollers cooperate with each other respectively to complete the conveying of the fabric; one side of the housing is fixedly installed with a first motor and a second motor. One end of the output shaft of the first motor rotatably penetrates one side of the housing and is fixedly connected to one end of one of the first conveying rollers, and one end of the output shaft of the second motor rotatably penetrates one side of the housing and is fixedly connected to one end of one of the second conveying rollers;

[0009] It further includes a stretching component for stretching the fabric;

[0010] It further includes two groups of flattening components for flattening the wrinkles on both sides of the fabric.

[0011] In a possible design, the stretching component includes lifting grooves formed on the outer walls of both sides of the outer shell. A stretching roller is arranged inside the outer shell. The stretching roller cooperates with the fabric to complete the stretching of the fabric. A fixing rod rotatably penetrates through the inside of the stretching roller. Both ends of the fixing rod are slidably connected to the inner walls of the two lifting grooves respectively. One end of the fixing rod is fixedly installed with an L-shaped mounting plate. The L-shaped mounting plate is slidably matched with one side of the outer shell. One side of the outer shell is fixedly installed with a fixing plate. The fixing plate is located above the L-shaped mounting plate. A cylinder is fixedly installed on the top of the fixing plate. One end of the piston rod of the cylinder slidably penetrates through the fixing plate and is fixedly connected to the top of the L-shaped mounting plate. The cylinder is used to drive the stretching roller to lift, so as to complete the adjustment of the stretching degree of the fabric.

[0012] In a possible design, the flattening component includes two rotating rods rotatably arranged on one side of the outer shell. One end of each of the two rotating rods rotatably penetrates through one side of the outer shell and is fixedly installed with a gear. The two gears mesh with each other to complete the synchronous reverse rotation of the two rotating rods. Connecting rods are fixedly installed on the outer walls of the two rotating rods. The other ends of the two connecting rods are fixedly installed with flattening rods. The two flattening rods are respectively in close contact with the upper and lower sides of the fabric to flatten the wrinkles that appear in the fabric during transportation. A fixed collar is fixedly sleeved on the outer wall of the rotating rod. A torsion spring is sleeved on the outer wall of the rotating rod. One end of the torsion spring is fixedly connected to one side of the fixed collar, and the other end of the torsion spring is fixedly connected to one side of the adjacent outer shell. The torsion spring is used to drive the flattening rod to continuously press against the fabric.

[0013] In a possible design, a scale is fixedly installed on one side of the outer shell. An indicating block is fixedly installed on one side of the L-shaped mounting plate.

At this time, driven by the gear, the two flattening rods located below will also move. At this time, the upper and lower two flattening rods on both sides move away from each other. The user needs to pass the fabric through the middle and then release the pulling of the flattening rods. At this time, under the action of the torsion spring, the upper and lower two flattening rods on both sides can clamp the fabric to facilitate the subsequent flattening of the fabric wrinkles; when the fabric is input between the limiting roller and the second conveying roller, it is also necessary to make the fabric located below the stretching roller to facilitate the subsequent stretching; then the user can start the first motor and the second motor to convey the fabric. When the fabric moves, when there are wrinkles in the fabric, the two flattening rods on that side will flatten the fabric, and no matter which side the wrinkles face, the mutual cooperation of the two flattening rods can ensure a good flattening effect on the fabric, and thus ensure a good stretching effect on the subsequent fabric; at the same time, the user can start the air cylinder, and the air cylinder pushes the L-shaped mounting plate to move, thereby completing the height adjustment of the stretching roller. After the stretching roller descends, it will maintain a certain height and can stretch the fabric well. And the user can judge the descending distance of the stretching roller according to the indication of the indicating block and the scale, so as to complete the precise stretching of the fabric, which can meet the stretching processing requirements of different fabrics and has a good use effect; the stretched fabric will be conveyed by the two second conveying rollers and then transmitted to the next processing equipment to complete the subsequent processing process.

[0028] Embodiment 1

[0029] Referring to Figures 1-4 , a stretching device includes:

[0030] The outer shell 1 is the main structure of the device. Two first conveying rollers 2, two limiting rollers 3 and two second conveying rollers 4 are rotatably connected inside it. Multiple conveying rollers are all installed in the outer shell 1 through their respective bearing seats to ensure smooth rotation; the two first conveying rollers 2, the two limiting rollers 3 and the two second conveying rollers 4 are arranged in sequence, and two adjacent conveying rollers cooperate with each other to complete the conveying of the fabric.

[0031] On one side of the outer shell 1, a first motor 5 and a second motor 6 are fixedly installed. The output shaft of the first motor 5 is fixedly connected to one end of one of the first conveying rollers 2 to drive it to rotate. Similarly, the output shaft of the second motor 6 is connected to one end of one of the second conveying rollers 4 to drive the other end of the fabric conveying, thereby ensuring the stability and synchronism of the fabric during the conveying process.

[0032] The stretching assembly mainly consists of a stretching roller 7, a fixing rod, an L-shaped mounting plate 12, a cylinder 11 and a fixing plate 10. Lifting grooves 8 are formed on the outer walls on both sides of the outer shell 1. The stretching roller 7 is slidably connected to the lifting grooves 8 through the fixing rod inside it to achieve up and down movement. One end of the fixing rod is fixedly installed with an L-shaped mounting plate 12. The L-shaped mounting plate 12 is slidably matched with the side wall of the outer shell 1 to ensure its stability without shaking during the lifting process. The fixing plate 10 is fixedly installed on one side of the outer shell 1 and is located above the L-shaped mounting plate 12. A cylinder 11 is installed on the fixing plate 10. One end of the piston rod of the cylinder 11 passes through the fixing plate 10 and is fixedly connected to the top of the L-shaped mounting plate 12. By controlling the telescopic movement of the cylinder 11, the user can drive the stretching roller 7 to move up and down, thereby adjusting the stretching degree of the fabric.

[0033] The flattening assembly includes two rotating rods 16, gears 17, connecting rods 15, flattening rods 9, fixed collar rings 18 and torsion springs 19.

[0034] This application can be used in the field of fabric processing technology and also in other fields applicable to this application.

[0035] Embodiment 2

[0036] Reference Figure 2 、 3 、4, on the basis of Embodiment 1, an improvement is made: A hot-pressing and forming fabric anti-wrinkle stretching device, which is applied to the field of fabric processing technology;

[0037] In order to precisely control the moving distance of the stretching roller 7, a scale 13 is fixedly installed on one side of the housing 1, and an indicating block 14 that cooperates with the scale 13 is fixed on the L-shaped mounting plate 12. Operators can, as needed, precisely adjust the position of the stretching roller 7 by reading the position of the indicating block 14 on the scale 13 to achieve precise stretching of different fabrics.

[0038] In this embodiment, the lengths of the two flattening rods 9 are relatively long, which can ensure that regardless of how the width of the fabric changes, the two flattening rods 9 on the same side can contact and clamp the side edges of the fabric.

[0039] In this embodiment, the two sets of flattening assemblies are located between the two first conveying rollers 2 and the two limiting rollers 3, while the stretching assembly is located between the two limiting rollers 3 and the two second conveying rollers 4. Such a layout design aims to first flatten the fabric and then perform stretching processing to avoid adverse effects caused by wrinkles during the stretching process of the fabric. At the same time, the end close to the first conveying roller 2 is set as the input end of the device to ensure that the fabric is fully flattened before entering the stretching area.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 5 and the second motor 6 are common knowledge, and they both belong to conventional means or well-known common sense. Therefore, they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0041] The working principle and usage process of this technical solution are as follows: When in use, the user can input the fabric from one end close to the first conveying roller 2 and complete the conveying of the fabric through two first conveying rollers 2, two limiting rollers 3, and two second conveying rollers 4; when inputting the fabric, the user should lift the flattening rods 9 on both sides. At this time, driven by the gear 17, the two flattening rods 9 located below will also move. At this time, the upper and lower two flattening rods 9 on both sides move away from each other. The user needs to pass the fabric through the middle and then release the pulling of the flattening rods 9. At this time, under the action of the torsion spring 19, the upper and lower two flattening rods 9 on both sides can clamp the fabric to facilitate the subsequent flattening of the fabric wrinkles; when the fabric is input between the limiting roller 3 and the second conveying roller 4, it is also necessary to make the fabric located below the stretching roller 7 to facilitate the subsequent stretching; then the user can start the first motor 5 and the second motor 6 to convey the fabric. When the fabric moves, when there are wrinkles in the fabric, the two flattening rods 9 on that side will flatten the fabric. And no matter which side the wrinkles face, the mutual cooperation of the two flattening rods 9 can ensure a good flattening effect on the fabric, and thus ensure a good stretching effect on the subsequent fabric; at the same time, the user can start the cylinder 11, and the cylinder 11 pushes the L-shaped mounting plate 12 to move, thereby completing the height adjustment of the stretching roller 7. After the stretching roller 7 descends, it will maintain a certain height and can stretch the fabric well. And the user can judge the descending distance of the stretching roller 7 according to the indication cooperation between the indicating block 14 and the scale 13, so as to complete the precise stretching of the fabric, which can meet the stretching processing requirements of different fabrics and has a good use effect; the stretched fabric will be conveyed by the two second conveying rollers 4 and then transmitted to the next processing equipment to complete the subsequent processing process.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
