Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a chopped yarn traveling device for a warp knitting machine. Background Art

[0002] A warp knitting machine is a machine used to weave fabrics. It uses one or more sets of parallel yarns, which are looped simultaneously on all the needles feeding the machine in the warp direction to form a knitted fabric. The chopped yarn travel device on the warp knitting machine ensures that the yarn flows evenly and steadily before being fed to the drive roller for chopping. This function prevents yarn turbulence and interlacing during the feeding process, thus ensuring smooth subsequent chopping and knitting.

[0003] Currently, the traditional chopped yarn traveling device of warp knitting machines on the market usually contains multiple components and mechanisms, and its structure is relatively complex, which not only increases the difficulty of manufacturing and maintenance, but also has poor stability and high failure rate.

[0007] In addition, a preferred structure is that the output end of the traveling drive device faces the slideway mounting seat and is provided with a traveling eccentric wheel.

[0008] In addition, a preferred structure is that a first pin is provided on the movable eccentric, and a first spherical bearing is provided on the first pin.

[0009] In addition, a preferred structure is that a second pin is provided on a side of the chopped yarn threading plate close to the traveling drive device, and a second joint bearing is provided on the second pin.

[0010] In addition, a preferred structure is that the first pin shaft and the second pin shaft are both provided with locking rings for preventing the first spherical bearing and the second spherical bearing from falling off.

[0011] In addition, a preferred structure is that a double-headed screw is provided on the first spherical bearing, and the other end of the double-headed screw is connected to the second spherical bearing.

[0012] In addition, a preferred structure is that a limit plate is fixedly provided on one end of the slide groove on the outside of the mounting base plate.

[0013] The beneficial effects of the present invention are as follows: through the driving of the movable eccentric wheel by the movable driving device, the first pin shaft, the first joint bearing, the double-headed screw, the second joint bearing and the second pin shaft can be driven to move, thereby driving the chopped yarn threading plate located on the slide groove to move back and forth, so as to realize the movable driving of the chopped yarn threading plate.

DETAILED DESCRIPTION

[0017] 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.

[0018] Reference Figure 1-2 A chopped yarn traveling device for a warp knitting machine comprises two parallel mounting bases 1, each of which is fixedly provided with a chute mounting seat 2. A vertical chute 4 is fixedly provided between the mounting bases 1 on either side, and both ends of the chute 4 are mounted on the chute mounting seats 2. A chopped yarn threading plate 5 is movably provided on the chute 4. A traveling drive device 3 is fixedly provided on one mounting base 1, and the chopped yarn threading plate 5 is driven and moved by the traveling drive device 3.

[0019] The chopped yarn feeder 5 is equipped with a U-shaped groove-like yarn guide channel embedded with wear-resistant materials such as ceramic rings to reduce friction between the yarn and the feeder. The ceramic rings are equipped with yarn guide holes and notches, with the notches being curved to facilitate yarn passage and on to the next process. It is worth noting that the specific structure and operation of the chopped yarn feeder 5 are well-known in the art and will not be elaborated upon here.

[0020] The output end of the traveling drive device 3 faces the chute mounting base 2 and drives a traveling eccentric 7. The traveling eccentric 7 is provided with a first pin 8, and a first spherical bearing 9 is provided on the first pin 8. The traveling drive device 3 drives the traveling eccentric 7, thereby driving the first pin 8 and the first spherical bearing 9 synchronously.

[0021] Among them, a second pin shaft 11 is provided on the side of the chopped yarn threading plate 5 close to the traveling drive device 3, and a second joint bearing 13 is provided on the second pin shaft 11. Through the setting of the second joint bearing 13, the second pin shaft 11 can be driven to move.

[0022] The first pin 8 and the second pin 11 are both provided with a locking ring 10 for preventing the first spherical bearing 9 and the second spherical bearing 13 from falling off. The provision of the locking ring 10 can prevent the first spherical bearing 9 or the second spherical bearing 13 from falling off from the first pin 8 or the second pin 11.

[0023] Wherein, the first spherical bearing 9 is provided with a double-ended screw 12, and the other end of the double-ended screw 12 is connected to the second spherical bearing 13. Through the provision of the double-ended screw 12, the first spherical bearing 9 and the second spherical bearing 13 can be connected together.

[0024] Among them, one end of the chute 4 is located on the outside of the mounting base 1 and is fixedly provided with a limit plate 6. Through the setting of the limit plate 6, one end of the chute 4 can be limited to prevent the chopped yarn threading plate 5 from falling off from the chute 4.

[0025] In this embodiment, when the operator drives the chopped yarn threading plate 5 to move, he only needs to control the output end of the traveling drive device 3 to rotate, thereby driving the traveling eccentric wheel 7 to rotate through the traveling drive device 3. The rotation of the traveling eccentric wheel 7 can cause the first pin 8 to rotate eccentrically around the central axis of the traveling eccentric wheel, thereby driving the first joint bearing 9 to move synchronously.

[0026] When the first joint bearing 9 moves, the second joint bearing 13 can move synchronously with the first joint bearing 9 through the double-headed screw 12. Since the other end of the second joint bearing 13 is connected to the chopped yarn threading plate 5 through the second pin 11, the movement of the second joint bearing 13 can drive the chopped yarn threading plate 5 to move back and forth on the chute 4, thereby realizing the floating drive of the chopped yarn threading plate 5.

[0027] This floating driving method for the chopped yarn threading plate 5 is not only simple in structure and low in cost, but also has a low failure rate, and can improve the stability of the chopped yarn threading plate 5 during operation.

[0028] In the present invention, the traveling eccentric wheel 7 is driven by the traveling drive device 3, which can drive the first pin shaft 8, the first joint bearing 9, the double-headed screw 12, the second joint bearing 13 and the second pin shaft 11 to move, thereby driving the chopped yarn threading plate 5 located on the slide groove 4 to move back and forth, so as to realize the traveling drive of the chopped yarn threading plate 5. This driving method is not only simple in structure and low in cost, but also has a low failure rate, and can improve the stability of the chopped yarn threading plate 5 during operation.

[0029] 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.
