Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and more specifically, to a warp knitting machine for textile fabric processing with a correction function. Background Technology

[0002] Using one or more groups of parallel yarns, which are fed into all the working needles of the machine in the warp direction, to form loops simultaneously to create a knitted fabric, this method is called warp knitting, the fabric is called warp-knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine.

[0003] When existing warp knitting machines are in operation, the yarn is drawn out from the yarn bobbin. The tension between different yarns may be different due to the quality differences of the yarns themselves (such as uneven thickness and different twist), which will cause the fabric to be pulled differently in the direction of the yarn than other parts, thus causing the fabric to deviate and affecting the quality of the textile fabric. In view of this, we propose a warp knitting machine for textile fabric processing with a correction function. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a warp knitting machine for textile fabric processing with a correction function, so as to solve the technical problem that current warp knitting machines are not convenient for individually controlling and adjusting the tension of each group of yarns.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a warp knitting machine for textile fabric processing with a correction function, comprising a warp knitting machine body, a yarn feeding structure arranged on the top of the warp knitting machine body, the yarn feeding structure including a bracket, the bracket being arranged on the warp knitting machine body, a yarn frame rotatably arranged on the top of the front side between the brackets, a tension adjustment structure arranged inside the yarn feeding structure below the yarn frame, the tension adjustment structure including a mounting plate, a plurality of mounting frames slidably arranged on the mounting plate, a semi-circular plate arranged on the front side of the mounting frame, and a yarn groove arranged around the semi-circular plate;

[0006] The inside of the wire groove is arranged with several sets of mating shafts, and the opening of the wire groove is arranged with several sets of equidistant wire locking structures.

[0007] This invention utilizes a designed tension adjustment structure. The front of the mounting plate of the tension adjustment structure is arranged with several sets of semi-circular plates via a mounting bracket. When each set of yarns on the yarn frame enters the warp knitting machine body, the yarn first passes through the groove of the corresponding semi-circular plate. Therefore, during the warp knitting machine's process of weaving the yarn into fabric, the yarn applies pressure to the semi-circular plates. At this time, a pressure sensor can monitor the tension of each set of yarns, and based on a preset tension value, an electric push rod can be controlled to move the semi-circular plates, thereby adjusting the tension of the corresponding yarns to reach the preset tension value. Therefore, it effectively avoids fabric deviation caused by differences in the tension of each set of yarns, ensuring the quality of the fabric. This invention also incorporates a first guide roller and a second guide roller rotatably arranged in the bracket. The tension adjustment structure is located below the yarn frame, with the first and second guide rollers located behind the tension adjustment structure, and both guide rollers are on the same vertical plane. The first guide roller, the second guide roller, and the tension adjustment structure form an equilateral triangle. The yarn is arranged in a circular pattern. Each group of yarns on the yarn frame enters from the top of the second guide roller, then passes through the corresponding semicircular plate on the tension adjustment structure, and finally through the first guide roller before entering the warp knitting machine body. Therefore, with the cooperation of the first and second guide rollers, the yarn can apply a stable horizontal backward force to the semicircular plate, ensuring the accuracy of yarn tension detection and further guaranteeing the effect of individual tension control and adjustment for each group of yarns. Several sets of cooperating shafts are arranged inside the groove of the semicircular plate of this invention. These shafts can rotate with the yarn, reducing the friction of the yarn passing through the groove, thereby reducing yarn wear and ensuring yarn quality. Several sets of locking structures are arranged around the opening of the groove. Pressure applied by the yarn to the locking structures causes the two sets of stop levers to rotate inward and separate, allowing the yarn to directly enter the groove. Then, with the cooperation of the elastic rod, the two sets of stop levers will reset, thus blocking the yarn in the groove and locking it inside, preventing the yarn from slipping out and allowing for better yarn routing within the groove.

[0008] Preferably, the mounting bracket is T-shaped, and the top and bottom of the mounting plate are provided with T-shaped grooves corresponding to the T-shaped rods of the mounting bracket, with the T-shaped rods passing through the T-shaped grooves.

[0009] Preferably, a pressure sensor is arranged in the center of the side of the mounting bracket facing away from the semi-circular plate, and an electric push rod is arranged on the pressure sensor. The cylinder of the electric push rod is arranged on the mounting plate.

[0010] Preferably, the opening of the wire groove is arranged with symmetrical opening grooves around its perimeter. The wire locking structure includes a stop bar and an elastic bar. The stop bar is rotatably arranged at the end of the opening groove, one end of the elastic bar is rotatably arranged on the stop bar, and the other end of the elastic bar is rotatably arranged in the opening groove.

[0011] Preferably, the end of the stop bar facing away from the opening slot is L-shaped, and the L-shaped ends of the two sets of symmetrically arranged opening slots overlap each other.

[0012] Preferably, the elastic rod includes a sleeve, a plug rod, and a spring. One end of the sleeve is rotatably connected to a stop rod, one end of the plug rod is rotatably connected to an opening slot, the other end of the plug rod is inserted into the sleeve, and the spring is located inside the sleeve.

[0013] Preferably, a first guide roller and a second guide roller are rotatably arranged inside the bracket. The first guide roller and the second guide roller are located behind the tension adjustment structure. The first guide roller and the second guide roller are on the same vertical plane. The first guide roller, the second guide roller and the tension adjustment structure are arranged in an isosceles triangle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes a designed tension adjustment structure. The front side of the mounting plate of the tension adjustment structure is arranged with several sets of semi-circular plates via a mounting frame. When each set of yarns on the yarn trough enters the warp knitting machine body, the yarn first passes through the groove of the corresponding semi-circular plate. Therefore, during the process of the warp knitting machine body weaving the yarn into fabric, the yarn applies pressure to the semi-circular plates. At this time, a pressure sensor can monitor the tension of each set of yarns, and according to the preset tension value, the electric push rod can be controlled to move the semi-circular plates, thereby adjusting the tension of the corresponding yarns to reach the preset tension value. Therefore, it can effectively avoid the deviation of the woven fabric caused by the different tensions of each set of yarns, ensuring the quality of the fabric. This solves the technical problem that current warp knitting machines are not convenient for individually controlling and adjusting the tension of each set of yarns. Therefore, this utility model has the advantage of individually controlling and adjusting the tension of each set of yarns, thereby achieving deviation correction.

[0016] 2. This utility model also incorporates a first guide roller and a second guide roller arranged rotatably within the support frame. The tension adjustment structure is located below the yarn frame, with the first and second guide rollers positioned behind the tension adjustment structure and on the same vertical plane. The first guide roller, the second guide roller, and the tension adjustment structure are arranged in an equilateral triangle. Therefore, each group of yarns on the yarn frame enters from the top of the second guide roller, passes through the corresponding semicircular plate on the tension adjustment structure, and finally passes through the first guide roller before entering the warp knitting machine body. Thus, with the cooperation of the first and second guide rollers, the yarn can exert a stable horizontal backward force on the semicircular plate, ensuring the accuracy of yarn tension detection and further guaranteeing the effect of individual control and adjustment of the tension of each group of yarns.

[0017] 3. The semi-circular plate of this utility model has several sets of mating shafts arranged inside the groove. The mating shafts can rotate with the yarn, which can reduce the friction of the yarn as it passes through the groove, thereby reducing wear on the yarn and ensuring its quality. In addition, several sets of locking structures are arranged around the opening of the groove. When the yarn applies pressure to the locking structure, it will cause the two sets of stop rods to rotate inward and separate, so that the yarn can directly enter the groove. Then, with the help of the elastic rod, the two sets of stop rods will return to their original positions, thereby blocking the yarn in the groove and locking the yarn in the groove to prevent it from slipping out, thus allowing the yarn to run better in the groove.

[0027] like Figures 1 to 7As shown, this utility model relates to a warp knitting machine for textile fabric processing with a correction function, including a warp knitting machine body 1. A yarn feeding structure 2 is arranged on the top of the warp knitting machine body 1. The yarn feeding structure 2 includes a bracket 201, which is arranged on the warp knitting machine body 1. A yarn frame 202 is rotatably arranged on the top of the front side between the brackets 201. A tension adjustment structure 3 is arranged inside the yarn feeding structure 2 below the yarn frame 202. The tension adjustment structure 3 includes a mounting plate 6. Several sets of mounting frames 8 are slidably arranged on the mounting plate 6. A semi-circular plate 7 is arranged on the front side of the mounting frame 8. A yarn groove 701 is arranged around the semi-circular plate 7. A pressure sensor 801 is arranged in the center of the side of the mounting frame 8 facing away from the semi-circular plate 7. An electric push rod 802 is arranged on the pressure sensor 801. The cylinder of the electric push rod 802 is arranged on the mounting plate 6.

[0028] When each set of yarns on the yarn rack 202 enters the warp knitting machine body 1, the yarns first pass through the groove 701 of the corresponding semicircular plate 7. Therefore, during the process of weaving the yarns into fabric in the warp knitting machine body 1, the yarns will apply pressure to the semicircular plate 7. At this time, the tension of each set of yarns can be monitored by the pressure sensor 801, and the electric push rod 802 can be controlled to move the semicircular plate 7 according to the preset tension value, thereby adjusting the tension of the corresponding yarns so that their tension values ​​reach the preset state. Therefore, it can effectively avoid the deviation of the fabric woven subsequently due to the different tension of each set of yarns, and ensure the quality of the fabric.

[0029] Specifically, the mounting bracket 8 has T-shaped rods at the top and bottom, and the mounting plate 6 has T-shaped grooves at the top and bottom that correspond to the T-shaped rods of the mounting bracket 8. The T-shaped rods pass through the T-shaped grooves. With the cooperation of its upper and lower T-shaped rods and the T-shaped grooves of the mounting plate 6, the mounting bracket 8 can slide smoothly back and forth on the mounting plate 6.

[0030] In an embodiment of this utility model, a plurality of sets of mating shafts 9 are rotatably arranged inside the wire groove 701, and a plurality of sets of equidistant wire locking structures 10 are arranged around the opening of the wire groove 701; symmetrical opening grooves 702 are arranged around the opening of the wire groove 701, and the wire locking structure 10 includes a stop bar 11 and an elastic bar 12. The stop bar 11 is rotatably arranged at the end of the opening groove 702, one end of the elastic bar 12 is rotatably arranged on the stop bar 11, and the other end of the elastic bar 12 is rotatably arranged in the opening groove 702; the end of the stop bar 11 facing away from the opening groove 702 is L-shaped, and the L-shaped ends of the two sets of symmetrically arranged opening grooves 702 overlap each other.

[0031] The shaft 9 can rotate with the yarn, reducing the friction of the yarn as it passes through the groove 701, thereby reducing yarn wear and ensuring yarn quality. When the yarn applies pressure to the stop levers 11 of the locking structure 10, the two sets of stop levers 11 will rotate inward to separate, and then the yarn can directly enter the groove 701. Then, with the cooperation of the elastic rod 12, the two sets of stop levers 11 will reset, thereby blocking the yarn in the groove 701 and locking the yarn in the groove 701 to prevent the yarn from slipping out of the groove 701, thus allowing for better yarn routing in the groove 701.

[0032] Specifically, the elastic rod 12 includes a sleeve 1201, an insert rod 1202, and a spring 1203. One end of the sleeve 1201 is rotatably connected to the stop rod 11, one end of the insert rod 1202 is rotatably connected to the opening slot 702, and the other end of the insert rod 1202 is inserted into the sleeve 1201. The spring 1203 is located inside the sleeve 1201. With the cooperation of the spring 1203, the insert rod 1202 can extend and retract within the sleeve 1201.

[0033] In an embodiment of this utility model, a first guide roller 4 and a second guide roller 5 are rotatably arranged inside the bracket 201. The first guide roller 4 and the second guide roller 5 are located behind the tension adjustment structure 3. The first guide roller 4 and the second guide roller 5 are on the same vertical plane. The first guide roller 4, the second guide roller 5 and the tension adjustment structure 3 are arranged in an isosceles triangle.

[0034] Each group of yarns on the yarn frame 202 enters from the top of the second guide roller 5, then passes through the corresponding semi-circular plate 7 on the tension adjustment structure 3, and finally passes through the first guide roller 4 before entering the warp knitting machine body 1. Therefore, with the cooperation of the first guide roller 4 and the second guide roller 5, the yarn can apply a stable horizontal backward force to the semi-circular plate 7, ensuring the accuracy of yarn tension detection and further ensuring the effect of individual control and adjustment of the tension of each group of yarns.

[0035] Working principle: This embodiment provides a warp knitting machine for textile fabric processing with a correction function. First, when each group of yarns on the yarn frame 202 enters the warp knitting machine body 1, the yarns first pass through the groove 701 of the corresponding semi-circular plate 7. Therefore, during the process of the warp knitting machine body 1 weaving the yarns into fabric, the yarns will apply pressure to the semi-circular plate 7. At this time, the tension of each group of yarns can be monitored by the pressure sensor 801, and the electric push rod 802 can be controlled to move the semi-circular plate 7 according to the preset tension value, thereby adjusting the tension of the corresponding yarns so that their tension values ​​reach the preset state. Therefore, it can effectively avoid the deviation of the fabric woven subsequently due to the different tension of each group of yarns, and ensure the quality of the fabric.

[0036] Secondly, each group of yarns on the yarn frame 202 enters from the top of the second guide roller 5, then passes through the corresponding semi-circular plate 7 on the tension adjustment structure 3, and finally passes through the first guide roller 4 before entering the warp knitting machine body 1. Therefore, with the cooperation of the first guide roller 4 and the second guide roller 5, the yarn can apply a stable horizontal backward force to the semi-circular plate 7, ensuring the accuracy of yarn tension detection and further ensuring the effect of individual control and adjustment of the tension of each group of yarns.

[0037] Secondly, the shaft 9 can rotate with the yarn, which can reduce the friction of the yarn as it passes through the groove 701, thereby reducing wear on the yarn and ensuring the quality of the yarn.

[0038] Finally, when the yarn applies pressure to the stop levers 11 of the locking structure 10, the two sets of stop levers 11 will rotate inward to separate, and then the yarn can directly enter the yarn groove 701. Then, with the cooperation of the elastic rod 12, the two sets of stop levers 11 will be reset, thereby blocking the yarn in the yarn groove 701 and locking the yarn in the yarn groove 701 to prevent the yarn from slipping out of the yarn groove 701, so that the yarn can be better routed in the yarn groove 701.

[0039] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
