Description

Technical Field

[0001] The utility model relates to the technical field of tension regulating devices, in particular to a tension regulating device for a water jet loom. Background Art

[0002] The water jet loom is a highly efficient and automated textile equipment that uses water jets to introduce weft yarns and warp yarns for interweaving. It is suitable for producing high-density fabrics with smooth surfaces. It has the characteristics of rapid production, strong adaptability, and high fabric quality. It is widely used in clothing fabrics, home textiles and other fields.

[0003] Existing tension devices for water jet looms mainly apply tension by pressing a tension roller against the fabric surface. However, the position of the tension roller is often fixed, and the surface tension cannot be adjusted in time according to different fabric types, resulting in uneven tension and affecting the quality of subsequent processed products. Utility Model Content

[0004] The purpose of the present utility model is to solve the following shortcomings in the prior art: the existing tension device for a water jet loom mainly applies tension by pressing a tension roller against the surface of the fabric, but the position of the tension roller is often fixed, and the size of the surface tension cannot be adjusted in time according to different types of fabrics, resulting in uneven tension and thus affecting the quality of subsequent processed products. A tension adjustment device for a water jet loom is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The two wheels are connected to each other with two cams, and the two wheels are connected with each other with a plurality of cams, and the two wheels are connected with each other with a plurality of cams.

[0007] Preferably, the locking component includes a connecting rod, a locking column and a handwheel fixedly installed at one end of the locking column. A mounting groove is provided on the surface of the fixing column near the bottom wall of the machine body, and a connecting rod is fixedly sleeved in the mounting groove. A first locking port is provided at the end of the connecting rod away from the fixing column, and a second locking port is provided on the surface of the first sprocket near the first locking port. The first locking port and the second locking port are both provided with the same thread, and the locking column is threadedly installed in the first locking port and the second locking port.

[0008] Preferably, the left and right side walls of the machine body are symmetrically provided with mounting openings, a discharging roller and a winding roller are provided in the machine body, and a plurality of rotating parts are provided in the plurality of mounting openings, and the two ends of the discharging roller and the winding roller are respectively connected to a plurality of rotating parts, and the rotating parts include a circular sleeve fixedly installed in the mounting opening, a roller shaft is rotatably installed in the circular sleeve, a plurality of rotating cylinders are slidably embedded between the outer ring and the inner ring of the roller shaft, the inner ring of the roller shaft is fixedly connected to the winding roller, and the side wall of the machine body is provided with a driving component for rotating the winding roller.

[0009] Preferably, the drive assembly includes two second sprockets of different sizes, wherein a larger second sprocket is fixedly connected to one end of the winding roller and is meshed with a second chain wrapped around the other smaller second sprocket, and a support plate is provided on the bottom wall of the machine body side, and a drive motor is fixedly mounted on the support plate, and the output shaft of the drive motor is fixedly connected to the smaller second sprocket through a rotating rod.

[0010] Preferably, a wastewater collecting device is provided on the bottom wall of the machine body, and the wastewater collecting device comprises a collecting box with both ends fixedly connected to the left and right side walls of the machine body, and an inverted V-shaped filter is fixedly installed in the collecting box.

[0011] Preferably, two balancing rollers are fixedly installed between the left and right side walls of the machine body at the same height as the winding roller, and the two balancing rollers are used to cooperate with the tension roller to adjust the tension on the surface of the fabric.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the tension needs to be adjusted, the locking component must be unlocked first, and then the corresponding first sprocket is rotated. Then, the other multiple first sprockets will be driven to rotate through the first chain. When the total length of the chain remains unchanged, the first sprocket is rotated clockwise. The cooperation between the multiple first sprockets will cause the slider to move downward. Then, the slider together with the strip block will carry the tension roller downward along the strip through-hole, and finally cooperate with the two balancing rollers to stretch the fabric, thereby increasing the tension on the fabric surface. Conversely, the first sprocket is rotated counterclockwise to reduce the tension on the fabric surface. The adjusting device can change the surface tension of different fabrics in time to prevent the uneven tension from affecting the quality of subsequent processed products.

[0014] The adjusting device includes a plurality of first sprockets. Because the movable pulley structure formed by the plurality of first sprockets is a labor-saving structure, the force required by the operator during the tension adjustment process is greatly reduced, making it easier to adjust the tension and preventing the situation in which work becomes difficult when the type of fabric is difficult to stretch and the tension on the fabric surface gradually increases.

[0015] The connection between the winding roller and the unwinding roller and the machine body is equipped with a roller. A plurality of rotating cylinders are embedded in the outer ring and the inner ring of the roller in a circular sliding manner. When the winding roller and the unwinding roller rotate, the sliding friction between the machine body and the roller body is converted into rolling friction, which reduces the friction force and improves the working efficiency of the drive motor.

[0016] During the use of the water jet loom, the wastewater produced will flow into the wastewater collection device. When the wastewater passes through the filter net, the fabric fibers mixed in it are filtered out and finally collected in the collection box, which is convenient for recycling and improves resource utilization.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0026] Reference Figures 1-6 The two ends of the first chain 7 are fixedly connected to the two fixed columns 3.

[0027] Two balancing rollers 23 are fixedly installed between the left and right side walls of the machine body 1 at the same height as the winding roller 15. The two balancing rollers 23 are used to cooperate with the tension roller 9 to adjust the tension on the surface of the fabric.

[0028] When the tension needs to be adjusted, the locking component must be unlocked first, and then the corresponding first sprocket 4 is rotated, and then the other multiple first sprockets 4 will be driven to rotate through the first chain 7. The two ends of the first chain 7 are fixedly connected to the two fixed columns 3 respectively. When the total length of the chain remains unchanged, the first sprocket 4 is rotated clockwise, and the multiple first sprockets 4 cooperate with each other to move the slider 6 downward, and then the slider 6 will move downward along the strip-shaped opening 8 together with the tension roller 9 together with the strip block 10, and finally cooperate with the two balancing rollers 23 to stretch the fabric, thereby increasing the tension on the fabric surface. Conversely, the first sprocket 4 is rotated counterclockwise to reduce the tension on the fabric surface. When the slider 6 moves to the top of the strip-shaped opening 8, the fabric is on the same horizontal plane and the surface tension is approximately zero.

[0029] The locking component includes a connecting rod 11, a locking column 12 and a handwheel 13 fixedly installed at one end of the locking column 12. A mounting groove is provided on the surface of the fixing column 3 near the bottom wall of the body 1, and the connecting rod 11 is fixedly sleeved in the mounting groove. A first locking port is provided at the end of the connecting rod 11 away from the fixing column 3, and a second locking port is provided on the surface of the first sprocket 4 near the first locking port. The first locking port and the second locking port are both provided with the same thread, and the locking column 12 is threadedly installed in the first locking port and the second locking port.

[0030] When the tension roller 9 moves to a certain position, the hand wheel 13 is turned clockwise to lock the locking column 12 with the thread in the second locking port. The position of the tension roller 9 is fixed by fixing the first sprocket 4, thereby fixing the required tension. Conversely, the hand wheel 13 is turned counterclockwise to make the locking column 12 leave the second locking port, thereby unlocking it and facilitating the adjustment of the tension.

[0031] The left and right side walls of the machine body 1 are symmetrically provided with mounting openings, and a discharging roller 14 and a winding roller 15 are provided in the machine body 1. Multiple rotating parts are provided in the multiple mounting openings, and the two ends of the discharging roller 14 and the winding roller 15 are respectively connected to multiple rotating parts. The rotating parts include a circular sleeve 16 fixedly installed in the mounting opening, and a roller shaft 17 is rotatably installed in the circular sleeve 16. Multiple rotating columns 18 are slidably embedded between the outer ring and the inner ring of the roller shaft 17. The inner ring of the roller shaft 17 is fixedly connected to the winding roller 15. The side wall of the machine body 1 is provided with a driving component for rotating the winding roller 15.

[0032] The drive assembly includes two second sprockets 19 of different sizes, one of the larger second sprockets 19 is fixedly connected to one end of the winding roller 15, and is meshed with the other smaller second sprocket 19 with a second chain 20 wound around it. A support plate is provided on the bottom wall of the side of the body 1, and a drive motor 21 is fixedly mounted on the support plate. The output shaft of the drive motor 21 is fixedly connected to the smaller second sprocket 19 through a rotating rod.

[0033] When the machine body 1 is ready to start running, the fabric on the unwinding roller 14 is prepared and the other end is connected to the winding roller 15. Then the drive motor 21 is started, and its output shaft drives the smaller second sprocket 19 to start rotating through the rotating rod, and then drives the other larger second sprocket 19 to rotate through the second chain 20, and then drives the winding roller 15 to rotate and start winding.

[0034] A wastewater collecting device is provided on the bottom wall of the machine body 1. The wastewater collecting device comprises a collecting box with both ends fixedly connected to the left and right side walls of the machine body 1. An inverted V-shaped filter screen 22 is fixedly installed in the collecting box.

[0035] During the use of the water jet loom, the wastewater produced will flow to the wastewater collection device. When the wastewater passes through the filter screen 22, the fabric fibers mixed therein are filtered out and finally collected in the collection box for easy recycling.

[0036] In the present invention, when the tension needs to be adjusted, the locking component must first be unlocked, and then the corresponding first sprocket 4 is rotated, and then the other multiple first sprockets 4 will be driven to rotate through the first chain 7. The two ends of the first chain 7 are fixedly connected to the two fixed columns 3 respectively. When the total length of the chain remains unchanged, the first sprocket 4 is rotated clockwise, and the multiple first sprockets 4 cooperate with each other to move the slider 6 downward, and then the slider 6 will move downward along the strip-shaped opening 8 together with the tension roller 9 together with the strip block 10, and finally cooperate with the two balancing rollers 23 to stretch the fabric, thereby increasing the tension on the surface of the fabric. Conversely, the first sprocket 4 is rotated counterclockwise to reduce the tension on the surface of the fabric, which is convenient for the operator to change the size of the surface tension of the fabric in time according to different types of fabrics, and prevent the uneven tension from affecting the quality of subsequent processed products.

[0037] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
