Description

Technical Field

[0001] This utility model relates to the field of needle-punched textile equipment technology, specifically a tension adjustment mechanism for a warp knitting machine. Background Technology

[0002] A warp knitting machine is a type of knitting machinery used to produce warp-knitted fabrics. It uses one or more sets of parallel warp yarns, which are simultaneously knitted by needles through looping and interlacing actions, forming fabrics with good longitudinal extensibility, high elasticity, and structural stability. Unlike weft knitting machines, warp knitting machines feed yarns longitudinally along the fabric, thus enabling efficient production of large quantities of highly stable knitted fabrics. They are widely used in clothing, home textiles, and industrial fabrics. Warp knitting machines are typically equipped with multiple guide bars, each controlling a set of warp yarns. The warp yarns from different guide bars must participate in looping according to a preset pattern. If the tension of each set of warp yarns is inconsistent, it will lead to uneven warp yarn feeding, causing skewed fabric patterns and disordered designs. Therefore, a tension adjustment mechanism is needed to support and adjust the warp yarn tension. Existing warp knitting machine tension adjustment mechanisms cannot effectively prevent warp yarn mixing and tangling, resulting in poor integrated implementation of warp yarn separation and adjustment. Furthermore, the fixed yarn feed position lacks flexibility. Therefore, a new warp knitting machine tension adjustment mechanism is needed.

[0003] Existing warp knitting machine tension adjustment mechanisms cannot effectively improve the integrated effect of warp yarn separation adjustment during operation, nor can they improve the flexibility of the adjustable yarn feed position. Therefore, there is an urgent need for a new warp knitting machine tension adjustment mechanism. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a tension adjustment mechanism for a warp knitting machine, so as to solve the problem that the existing tension adjustment mechanism for warp knitting machines cannot effectively improve the integrated effect of the device in adjusting the warp yarn separation, and cannot improve the flexibility of the device in adjusting the yarn inlet position.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment mechanism for a warp knitting machine, comprising an adjustment table, a limiting groove formed on the side end of the adjustment table, a clamping shaft installed at the inner end of the limiting groove, a lower clamping cylinder installed at the outer end of the clamping shaft, a locking bolt installed on the side end of the clamping shaft, a clamping rod installed at the upper end of the clamping shaft, an upper clamping shaft installed at the outer end of the clamping rod, an upper clamping cylinder installed at the outer end of the upper clamping shaft, and a tension roller installed at the middle end of the adjustment table.

[0006] An inner top spring is installed at the inner end of the adjusting platform. A retaining bolt is installed at the front end of the inner top spring. A bearing plate is installed at the front end of the retaining bolt. A connecting shaft is installed at the inner end of the bearing plate. A loading shaft is installed at the front end of the connecting shaft. A connecting bolt is installed at the upper end of the loading shaft. A limit adjusting cylinder is installed at the outer end of the loading shaft.

[0007] Preferably, the lower clamping cylinder forms a rotating structure with the adjusting table via a clamping plate shaft, and the clamping plate shaft is threadedly connected to the adjusting table via a locking bolt.

[0008] Preferably, the upper clamping shaft is engaged with the clamping plate shaft via a clamping rod, and the upper clamping cylinder forms a rotating structure with the clamping plate shaft via the upper clamping shaft.

[0009] Preferably, the bolt forms a telescopic structure with the adjusting table through an inner top spring, and the bearing plate is engaged with the adjusting table through the bolt.

[0010] Preferably, the connecting disc shaft forms a rotating structure with the adjusting table through the bearing disc, and the connecting bolt is threadedly connected to the connecting disc shaft through the connecting bolt.

[0011] Preferably, the limiting adjustment cylinder forms a rotating structure with the adjustment table via the loading shaft, and the limiting adjustment cylinders are arranged in a gapless contact manner with the central axis of the loading shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes an adjustment platform, tension roller, bearing disc, connecting disc shaft, loading shaft, connecting bolt, and limit adjustment cylinders. Based on the number of warp yarns during warp knitting, a corresponding number of limit adjustment cylinders are mounted on the loading shaft. The width of the limit adjustment cylinders can be selected according to the warp yarn thickness, ensuring the warp yarns pass smoothly through the partitioned space, avoiding mutual friction, entanglement, or knotting, thus laying the foundation for subsequent tension adjustment. After assembly, the connecting disc shaft is inserted into the end of the loading shaft and tightened with the connecting bolt, firmly securing all the limit adjustment cylinders to the loading shaft, preventing loosening or displacement without affecting rotation. After the warp yarns exit the partitioned space of the limit adjustment cylinders, they need to pass through the tension roller before entering the knitting area. At this time, by rotating the bearing disc, the loading shaft and the limit adjustment cylinder can be rotated clockwise or counterclockwise as a whole. During the rotation, the angle of the warp yarn around the tension roller will change. If it rotates clockwise, the contact arc length between the warp yarn and the tension roller increases, the warp yarn is further tightened, and the tension increases. If it rotates counterclockwise, the contact arc length decreases, the warp yarn relaxes, and the tension decreases. By assembling limit adjustment cylinders of different numbers and widths, it can flexibly adapt to different warp yarn numbers, solve the problem of warp yarn mixing and entanglement, realize continuous tension adjustment, simple operation and controllable precision, and improve the integrated effect of the device on warp yarn separation adjustment. This invention utilizes an adjustment platform, a limiting groove, a clamping plate shaft, a lower clamping cylinder, a tightening bolt, a clamping rod, an upper clamping shaft, and an upper clamping cylinder. The openings at both ends of the upper clamping shaft are aligned with the clamping rod on the clamping plate shaft. After insertion, the clamping rod is rotated 90 degrees, firmly locking the upper clamping shaft and fixing the position of the upper clamping cylinder, preventing it from moving axially or falling off. The upper and lower clamping cylinders are parallel and opposite each other; when they approach each other, the warp yarn is tightly clamped in the middle, thus initially adjusting the basic tension of the warp yarn. After loosening the tightening bolt, the clamping plate shaft can slide freely up and down along the limiting groove of the adjustment platform. Since the upper clamping cylinder is fixed to the clamping plate shaft via the upper clamping shaft, the movement of the clamping plate shaft will cause the upper clamping cylinder to move up and down synchronously. When adjusted to a suitable feeding position, the tightening bolt is tightened to press against the surface of the adjustment platform. Friction force fixes the clamping plate shaft in its current position, preventing positional shift due to vibration during weaving and improving the flexibility of the device's adjustable yarn feeding position.

A clamping shaft 3 is installed inside the limiting groove 2. A lower clamping cylinder 4 is installed on the outer end of the clamping shaft 3. A locking bolt 5 is installed on the side end of the clamping shaft 3. A clamping rod 6 is installed on the upper end of the clamping shaft 3. An upper clamping shaft 7 is installed on the outer end of the clamping rod 6. An upper clamping cylinder 8 is installed on the outer end of the upper clamping shaft 7. A tension roller 9 is installed in the middle of the adjustment table 1. The lower clamping cylinder 4 forms a rotating structure with the adjustment table 1 via the clamping shaft 3, and the clamping shaft 3 is threadedly connected to the adjustment table 1 via the locking bolt 5. The upper clamping shaft 7 is engaged with the clamping shaft 3 via the clamping rod 6, and the upper clamping cylinder 8 forms a rotating structure with the clamping shaft 3 via the upper clamping shaft 7. The openings at both ends of the upper clamping shaft 7 are aligned with the clamping rod 6 on the clamping shaft 3, and after insertion, the clamping rod 6 is rotated... Turn 90 degrees. At this time, the clamping rod 6 will firmly lock the upper clamping shaft 7, thereby fixing the position of the upper clamping cylinder 8 and preventing it from moving or falling off along the axial direction of the clamping rod 6. The upper clamping cylinder 8 and the lower clamping cylinder 4 are parallel and opposite each other. When the two are close, the warp is tightly clamped in the middle, thereby initially adjusting the basic tension of the warp. After loosening the locking bolt 5, the clamping plate shaft 3 can slide freely up and down along the limiting groove 2 of the adjusting table 1. Since the upper clamping cylinder 8 is fixed on the clamping plate shaft 3 through the upper clamping shaft 7, the movement of the clamping plate shaft 3 will drive the upper clamping cylinder 8 to move up and down synchronously. After adjusting to a suitable feeding position, tighten the locking bolt 5 to press it against the surface of the adjusting table 1. The clamping plate shaft 3 is fixed in the current position by friction, avoiding position displacement caused by vibration during the weaving process and improving the flexibility of the device's adjustable feeding position.

[0018] Please see Figures 1-5A tension adjustment mechanism for a warp knitting machine includes an inner top spring 10 installed at the inner end of an adjustment table 1, a retainer 11 installed at the front end of the inner top spring 10, a bearing plate 12 installed at the front end of the retainer 11, a connecting shaft 13 installed at the inner end of the bearing plate 12, a loading shaft 14 installed at the front end of the connecting shaft 13, a connecting bolt 15 installed at the upper end of the loading shaft 14, and a limit adjustment cylinder 16 installed at the outer end of the loading shaft 14. The retainer 11 and the adjustment table 1 form a telescopic structure through the inner top spring 10, and the bearing plate 12 is engaged with the adjustment table 1 through the retainer 11. The connecting shaft 13 and the adjustment table 1 form a rotating structure through the bearing plate 12, and the connecting bolt 15 is threadedly connected to the connecting shaft 13 through the connecting bolt 15. The limit adjustment cylinder 16 is connected to the adjustment table 1 through the loading shaft 14. The rotating structure is formed, and the limiting adjustment cylinders 16 are arranged in a gapless contact manner around the central axis of the loading shaft 14. According to the number of warp yarns during warp knitting, a corresponding number of limiting adjustment cylinders 16 are installed on the loading shaft 14. The width of the limiting adjustment cylinders 16 can be selected according to the thickness of the warp yarns to ensure that the warp yarns pass smoothly in the partition space and avoid mutual friction, entanglement or knotting, laying the foundation for subsequent tension adjustment. After assembly, the connecting shaft 13 is inserted into the end of the loading shaft 14 and tightened with the connecting bolt 15, so that all the limiting adjustment cylinders 16 are firmly restricted on the loading shaft 14 and cannot be loosened or moved, but it does not affect its rotation. After the warp yarns pass through the partition space of the limiting adjustment cylinders 16, they need to go around the tension roller 9 before entering the knitting area. At this time, by rotating the bearing plate 12, the loading shaft 14 and the limit adjustment cylinder 16 can be rotated clockwise or counterclockwise as a whole. During the rotation, the angle of the warp yarn around the tension roller 9 will change. If it rotates clockwise, the contact arc length between the warp yarn and the tension roller 9 increases, the warp yarn is further tightened, and the tension increases. If it rotates counterclockwise, the contact arc length decreases, the warp yarn relaxes, and the tension decreases. By assembling limit adjustment cylinders 16 of different numbers and widths, different warp yarn numbers can be flexibly adapted, solving the problem of warp yarn mixing and entanglement, realizing continuous tension adjustment, simple operation and controllable precision, and improving the integrated effect of the device on warp yarn separation adjustment.

[0019] Working principle: In use, first insert the upper clamping shaft 7 into the clamping rod 6 installed on the clamping plate shaft 3 through the left and right openings, and rotate the clamping rod 6 90 degrees to fix the position of the upper clamping cylinder 8. This clamps the warp thread between the upper clamping cylinder 8 and the lower clamping cylinder 4. Then, operate the clamping plate shaft 3 to move up and down in the limiting groove 2 to a suitable position, and then turn the tightening bolt 5 to fix the position of the clamping plate shaft 3 on the adjusting table 1. The up and down position of the warp thread is adjusted in one clamping operation, which improves the flexibility of the device's adjustable thread feeding position. The required width of the limiting adjusting cylinder 16 can be installed on the loading shaft 14 to guide the warp thread according to the number of warp threads. Then, insert the connecting disc shaft 13 into the other end of the loading shaft 14 and connect the connecting disc shaft to the other end of the loading shaft 14. Bolt 15 encapsulates the limiting adjustment cylinder 16, and the rotation of the bearing plate 12 on the adjustment table 1 allows the limiting adjustment cylinder 16 to receive the warp and rotate clockwise or counterclockwise around the tension roller 9 to a suitable direction, thereby adjusting the tension of the warp wire between the tension roller 9 and the limiting adjustment cylinder 16. The force of the inner top spring 10 in the adjustment table 1 causes the latch 11 to move and engage with the opening on the bearing plate 12, thereby fixing the position of the limiting adjustment cylinder 16 and the loading shaft 14, improving the integrated effect of the device in warp separation adjustment. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
