Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing, in particular to a fabric opening and discharging device for extra-wide fabrics. Background Art

[0002] Width opening is a common process in the printing and dyeing process. It primarily involves fully expanding the width of rope-bound or half-rope-bound fabrics to create a flat surface. During fabric processing, if the fabric is not fully opened, it can be squeezed by rotating components such as guide rollers and nip rollers, forming undesirable wrinkles and resulting in defective products. Therefore, a width opening device is required to allow for fabric width opening during production.

[0003] In the industry, it is necessary to cut fabrics of different widths. The width is based on the effective width of the fabric in the weft direction. The conventional width will vary according to the type and purpose of the fabric, but in general, the common widths are usually within a certain range, such as the common narrow width, medium width and regular width. Extra-wide fabrics usually refer to fabrics whose width exceeds these conventional standards. Usually, the width of extra-wide fabrics will far exceed the conventional standard of 60 inches (152 cm) or wider, and may reach several meters wide or even wider. Such fabric design can provide a larger working space and less splicing, such as large murals, interior decorations, bed sheets, curtains, etc. Against the background of continuous advancement of textile machinery, the technical capabilities of producing extra-wide fabrics are also constantly improving, making wider fabrics possible.

[0004] With the advancement of printing and dyeing technology, new processing methods for printing and dyeing equipment are emerging in an endless stream. The continuous extra-wide open-width gas-liquid finishing machine is one of them. Unlike conventional simple opening devices, the continuous extra-wide open-width gas-liquid finishing machine has more stringent requirements. First, the continuous requirement is that the opening device can perform continuous processing work per unit time, that is, the efficiency requirement is higher. Secondly, the extra-wide requirement is that the opening device can process fabrics with a wider width under continuous working conditions, such as 3-meter fabrics, that is, the capacity requirement is greater. The existing opening and discharging device has a simple structure and a small opening torque. When the vehicle speed increases, the fabric cannot be fully opened, which increases the occurrence of defects such as wrinkles and abrasions, and cannot meet the production requirements of the above-mentioned extra-wide fabric opening efficiency. Utility Model Content

[0005] Aiming at the technical problem that the existing opening device cannot meet the requirements of the opening production of extra-wide fabrics, the utility model provides an opening and discharging device for extra-wide fabrics, which can meet the continuous opening production requirements of extra-wide equipment and improve production efficiency.

[0006] The utility model provides a cloth-opening and discharging device for extra-wide fabrics, comprising a cloth-opening frame, on which a first cloth-opening beater, a first width expander, a second cloth-opening beater, a second width expander, and a cloth-discharging centering device are sequentially installed along the direction of the fabric. The direction of the fabric is in a "∣" shape or an "N" shape. A padder is provided below the cloth-discharging frame. The function of the padder is to squeeze out and recover working fluid on the surface of the fabric through the squeezing action of two rollers. At the same time, the squeezing action can further squeeze and flatten the fabric after the width is opened, thereby improving the fabric surface effect. A cloth-discharging swing mechanism is also installed on the cloth-discharging frame, which functions to swing and discharge the fabric.

[0007] When the fabric direction is in the shape of "∣", the first opening beater, the first expander, the second opening beater, the second expander, and the cloth outlet centering device are arranged in a straight line from top to bottom, and a first cloth guide roller is installed on the cloth outlet rack above the first opening beater, and a second cloth guide roller is installed on the cloth outlet rack below the cloth outlet centering device. The distance between the first cloth guide roller and the second cloth guide roller is 4000~7000mm;

[0008] When the fabric direction is "N" shape, a first vertical frame and a second vertical frame are provided on the cloth discharge frame, the first opening beater and the first expander are installed on the first vertical frame from top to bottom, the second opening beater, the second expander and the cloth discharge centering device are installed on the second vertical frame from top to bottom, the first cloth guide roller is installed on the top of the first vertical frame, the third cloth guide roller is installed on the bottom of the first vertical frame, and the fourth cloth guide roller is installed on the top of the second vertical frame. The sum of the distance between the first cloth guide roller and the third cloth guide roller, the distance between the third cloth guide roller and the fourth cloth guide roller, and the distance between the fourth cloth guide roller and the padder is 4000~7000mm.

[0009] Furthermore, the first opening beater and the second opening beater are both double-wing beaters, and their function is to make the fabric slide according to the angles of the double wings during the rotating beating process, thereby opening the fabric.

[0010] Furthermore, the first expander and the second expander are both thread expanders.

[0011] Furthermore, the thread expander includes at least two thread expanding rollers, and the surfaces of the thread expanding rollers are provided with left-handed and right-handed threads from the middle to both ends respectively.

[0012] Furthermore, the first expander includes two threaded expander rollers, and the second expander includes three threaded expander rollers.

[0013] Furthermore, the fabric centering device is a photoelectric centering device. Its function is to adjust the centering of the fabric. When the fabric is skewed, it can be corrected by adjusting the tension and friction.

[0014] The beneficial effect of the present invention is that the cloth opening and discharging device for extra-wide fabrics provided by the present invention limits the width opening action distance to 4000~7000mm, increases the adjustment force distance, and at the same time, the present invention changes the existing single-width opening beater into a double-width opening beater, and then uses two spiral expanders to further open the fabric width, and finally corrects the fabric operation through the cloth discharge centering device, thereby realizing the width opening production according to the equipment operating speed in a short time, and fully expanding the fabric width, reducing the generation of defects, and smoothly entering the next production process.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 The present invention provides a fabric discharging device for extra-wide fabrics, comprising a fabric discharging frame 8. The fabric discharging frame 8 is vertical, with an integral outer frame made of folded steel plate. Its width is adapted to the width of the fabric. The fabric discharging frame 8 is linearly mounted, from top to bottom, with a first fabric guide roller 1, a first fabric opening beater 2, a first width expander 3, a second fabric opening beater 4, a second width expander 5, a fabric discharging centering device 6, and a second fabric guide roller 7. The distance between the first fabric guide roller 1 and the second fabric guide roller 7 is 4800 mm. A fabric discharging manipulation mechanism 9 is also mounted on the fabric discharging frame 8. The various components are linearly mounted in a "∣" shape, aligned with the direction of the fabric 10. The structural width of each component is adapted to the width of the fabric discharging frame 8, ranging from 2500 to 3600 mm.

[0024] The first cloth guide roller 1 and the second cloth guide roller 7 are used to support and guide the movement direction of the fabric. Both cloth guide rollers are composed of a shaft head, a blind head and a roller body, and the roller body is made of a chrome-plated seamless steel pipe.

[0025] The cloth discharging and swinging mechanism 9 is connected to the cloth discharging frame 8 by a link. Its function is to pull the fabric to swing at an appropriate frequency so that the fabric falls flatly into the cloth piling vehicle.

[0026] The present invention further comprises a padder 11, which is located between the second cloth guide roller 7 and the cloth outlet manipulation mechanism 9. The function of the padder 11 is to squeeze out and recover the working fluid on the surface of the fabric through the squeezing action of the two rollers, and at the same time, the squeezing action can further squeeze and flatten the fabric after the width is opened, thereby improving the fabric surface effect.

[0027] Figure 2 The structure of the first opening beater 2 and the second opening beater 3 of the present invention is shown. Both are double-wing beaters. Their function is to open the fabric by sliding according to the angles of the double wings during the rotating beating process.

[0028] The first expander 3 and the second expander 5 are both thread expanders, such as Figure 3 As shown. The threaded expander includes at least two threaded expanding rollers. The principle behind the threaded expander rollers is the unique threaded design of their roller surfaces. This design creates left-hand and right-hand threads extending from the center of the rollers to their ends. When the rollers rotate, these threads interact with the fabric, expanding the fabric. To enhance the expansion effect, the first expander 3 of this utility model includes two threaded expanding rollers, and the second expander 5 includes three threaded expanding rollers.

[0029] The cloth outlet centering device 6 is a photoelectric centering device, which includes a correction roller, which mainly plays a centering adjustment role on the fabric. When the fabric deviates from the center during the running route, the angle, tension and friction of the correction roller are adjusted to correct the fabric.

[0030] The cloth guide roller, expander, photoelectric centering device and cloth discharging and manipulating mechanism used in the present invention can all be obtained in the prior art and are installed on the cloth discharging frame 8 in a conventional manner.

[0031] Examples of the utility model work:

[0032] First, the utility model is set at the cloth outlet position of the continuous extra-wide open-width air-liquid finishing machine. The width of the air-liquid finishing fabric is 3.4m. Then the free end of the finished fabric 10 is connected to the guide cloth, and the cloth is pressed. Figure 1 The cloth passes through the first cloth guide roller 1, the first opening beater 2, the first expander 3, the second opening beater 4, the second expander 5, the cloth outlet centering device 6, the second cloth guide roller 7, the padder 11, and finally is discharged through the cloth outlet manipulation mechanism 9. After the application of the utility model, the technical effect of increasing the opening cloth outlet speed to 40m / min can be achieved, and the defects on the cloth surface can be significantly reduced.

[0033] Example 2

[0034] like Figure 4 , Example 2 is different from Example 1 in that the fabric 10 has an "N" shape, and a first vertical frame 81 and a second vertical frame 82 are provided on the cloth discharge frame 8. The first opening beater 2 and the first expander 3 are installed on the first vertical frame 81 from top to bottom, and the second opening beater 4, the second expander 5, and the cloth discharge centering device 6 are installed on the second vertical frame 82 from top to bottom. The first cloth guide roller 1 is installed at the top of the first vertical frame 81, the third cloth guide roller 12 is installed at the bottom of the first vertical frame 81, and the fourth cloth guide roller 13 is installed at the top of the second vertical frame 82. The sum of the distances between the first cloth guide roller 1 and the third cloth guide roller 12, the distance between the third cloth guide roller 12 and the fourth cloth guide roller 13, and the distance between the fourth cloth guide roller 13 and the padder 11 is 4800 mm.
