Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to the faucet of a jacquard weaving machine. Background Technology

[0002] Jacquard ribbon weaving machines are suitable for weaving various round or flat non-elastic and elastic ropes and ribbons. They are mainly used to weave various ropes and ribbons, shoelaces, elastic bands, decorative ribbons, high-tensile ribbons, fishing net lines, fishing lines, trailer ropes, marine ropes, sports belts, curtain ribbons, wires, fibers, and other high-quality products. In addition, the jacquard ribbon weaving machine adopts a computer-controlled double-acting jacquard head and uses an upper-opening needle selection system. It can be equipped with standard, enlarged, or double-knitting, medium-high-low jacquard openings. The head is installed on the central support, which is convenient for loading and unloading, and the design is simple and easy to operate.

[0003] Currently, the head drive device of a jacquard ribbon loom is used to move up and down during the jacquard process to extract the warp yarns. The head drive device usually uses two eccentric wheels to rotate and drive an external connecting arm to swing up and down. The connecting arm is located below the jacquard arm, so the jacquard arm rotates up and down around one end as an axis, which is the lever principle that makes the jacquard knife jump up and down, thereby extracting the warp yarns. Since one end of the jacquard arm is a rotating end and the other end is connected to the jacquard knife, the force of the connecting arm swinging up and down is driven by the contour trajectory of the two eccentric wheels, which drives the jacquard arm to swing up and down, thus driving the jacquard knife to move up and down. As a result, the driving force consumed to drive the eccentric wheels to rotate is relatively large, which leads to high power output and energy consumption of the drive component, and is not energy-efficient. Therefore, the head drive device of the jacquard ribbon loom is proposed. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] The head of a jacquard ribbon weaving machine includes a head frame and a knife-lifting assembly vertically and movably installed inside the head frame. A crossbeam assembly that drives and cooperates with the knife-lifting assembly is provided at the top of the outer side of the head frame, and each crossbeam assembly is driven and cooperated with an arm ring assembly. The arm ring assemblies are all vertically located on one side of the outer side of the head frame. A first transmission component that drives and cooperates with the arm ring assembly and a second transmission component that drives and cooperates with the knife-lifting assembly are respectively provided on both sides of the bottom of the outer side of the head frame. The head frame is also provided with a driving component that drives and cooperates with the first transmission component and the second transmission component.

[0006] Preferably, the first transmission component is provided with a second transmission belt that drives and cooperates with the driving component, and the first transmission component is also provided with a second tensioning pulley that drives and cooperates with the second transmission belt. The second tensioning pulley is located at the bottom end of the outer side of the head frame, and the driving component is provided with a second synchronous belt drive pulley that drives and cooperates with the second transmission belt.

[0007] Preferably, the second transmission assembly is provided with a connecting rod that drives and cooperates with the driving member, and the two ends of the connecting rod are respectively hinged to the second transmission assembly and the driving member, and the second transmission assembly is provided with a third transmission belt that drives and cooperates with the blade lifting assembly.

[0008] Preferably, the second transmission assembly is further provided with a first synchronous belt drive pulley that drives and cooperates with the third transmission belt, and the first synchronous belt drive pulley is movably disposed on the outside of the faucet frame, and the third transmission belt is provided with a first tension pulley that drives and cooperates with it, and the first tension pulley is disposed on the outside of the faucet frame.

[0009] Preferably, a swing arm assembly is provided between the faucet frame and the crossbeam assembly, and the swing arm assembly is movably and crosswise arranged on the outside of the faucet frame, and the two ends of the swing arm assembly are respectively hinged to the crossbeam assembly and the arm ring assembly.

[0010] Preferably, the head frame is further provided with a first solenoid valve fixing bracket and a second solenoid valve fixing bracket for fixing the solenoid valve, and the head frame is provided with a first head base piece and a second head base piece for supporting it, and the head frame is also provided with a first guide plate and a second guide plate for guiding the warp yarns, and a head protective cover is installed on the outside of the head frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when the first transmission assembly and the second transmission assembly are driven to rotate by the driving component, the first transmission assembly drives the arm ring assembly to move up and down in a staggered manner. At the same time as the arm ring assembly moves up and down, the cross beam assembly swings in a cross manner. When the cross beam swings in a cross manner, it drives one of the lifting knives in the lifting knife assembly to move up and down inside the head frame. The second transmission assembly drives the other lifting knife in the lifting knife assembly to move up and down inside the head frame. This allows the lifting knife assembly to move up and down in a staggered manner during the jacquard process, which enables the simultaneous extraction of different types of warp yarns and allows different types of warp yarns to form a time difference during the extraction process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4In this embodiment of the utility model, the head of the jacquard ribbon weaving machine includes a head frame 2 and a lifting knife assembly 21 vertically and movably disposed inside the head frame 2. A cross beam assembly 12 is provided at the top of the outer side of the head frame 2, which drives and cooperates with the lifting knife assembly 21. Each cross beam assembly 21 is driven and cooperated with an arm ring assembly 11, and each arm ring assembly 11 is vertically located on one side outside the head frame 2. A first transmission assembly 9 and a second transmission assembly 10 that drive and cooperate with the arm ring assembly 11 are respectively provided on both sides of the bottom of the outer side of the head frame 2. The head frame 2 is also provided with a driving component (not shown in the figure) that drives and cooperates with the first transmission assembly 9 and the second transmission assembly 10. When the first transmission assembly 9 and the second transmission assembly 10 are driven to rotate by the driving component, the first transmission assembly 9 drives the arm ring assembly 11 to move up and down in a staggered manner. At the same time as the arm ring assembly 11 moves up and down, it also causes the cross beam 21 to swing in a cross manner. When the cross beam 21 swings in a cross manner, it drives one of the lifting knives in the lifting knife assembly 21 to move up and down inside the head frame 2. The second transmission assembly 10 drives the other lifting knife in the lifting knife assembly 21 to move up and down inside the head frame 2. This allows the lifting knife assembly 21 to move up and down in a staggered manner during the jacquard process, which enables the simultaneous extraction of different types of warp yarns and allows different types of warp yarns to form a time difference during the extraction process.

[0021] The first transmission assembly 9 is provided with a second transmission belt (not shown in the figure) that drives and cooperates with the driving member, and the first transmission assembly 9 is also provided with a second tensioning pulley 19 that drives and cooperates with the second transmission belt. The second tensioning pulley 19 is located at the bottom end of the outer side of the head frame 2, and the driving member is provided with a second synchronous belt drive pulley 18 that drives and cooperates with the second transmission belt. Thus, when the driving member drives the second synchronous belt drive pulley 18 to rotate, it drives the first transmission assembly 9 to rotate on the head frame 2 through the second transmission belt.

[0022] The second transmission assembly 10 is provided with a connecting rod 17 that drives the driving member, and the two ends of the connecting rod 17 are respectively hinged to the second transmission assembly 10 and the driving member. The second transmission assembly 10 is provided with a third transmission belt (not shown in the figure) that drives the lifting knife assembly 21. Thus, when the driving member drives the connecting rod 17 to reciprocate during operation, it causes the second transmission assembly 10 to rotate. When the second transmission assembly 10 rotates, it drives the lifting knife assembly 21 to move up and down inside the head frame 2 through the third transmission belt.

[0023] The second transmission assembly 10 is further provided with a first synchronous belt drive pulley 15 that is driven and cooperates with the third transmission belt. The first synchronous belt drive pulley 15 is movably disposed on the outside of the head frame 2. The third transmission belt is provided with a first tension pulley 16 that is driven and cooperates with it. The first tension pulley 16 is disposed on the outside of the head frame 2.

[0024] A swing arm assembly 7 is provided between the dragon head frame 2 and the cross beam assembly 12. The swing arm assembly 7 is movably and crosswise arranged on the outside of the dragon head frame 2. The two ends of the swing arm assembly 7 are respectively hinged to the cross beam assembly 12 and the arm ring assembly 11. This allows the arm ring assembly 11 to move up and down outside the dragon head frame 2, causing the swing arm assembly 7 to swing crosswise, which in turn drives the cross beam assembly 12 to move the knife lifting assembly 21 up and down inside the dragon head frame 2.

[0025] The head frame 2 is also provided with a first solenoid valve fixing frame 13 and a second solenoid valve fixing frame 20 for fixing the solenoid valve. The head frame 2 is also provided with a first head foot piece 3 and a second head foot piece 6 for support. The head frame 2 is also provided with a first guide plate 4 and a second guide plate 5 for guiding the warp yarns. The head frame 2 is also provided with a head protective cover 1 installed on the outside of the head frame 2.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
