Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to an automatic edge yarn rack device. Background Art

[0002] The edge yarn rack of a computerized flat knitting machine is a device that provides a certain tensile force to the yarn during knitting.

[0003] Chinese Patent CN212713969U discloses an edge yarn rack of a computerized flat knitting machine, which includes a frame body. A broken yarn alarm is arranged on the frame body. The broken yarn alarm includes a jump rod and a detection rod, both of which rotate on the frame body. A plurality of tension mechanisms are arranged on the frame body. The mounting plate is fixedly arranged on the frame body. One end of the mounting rod is fixedly arranged on the mounting plate. There are two clip pieces sleeved on the mounting rod, and the two clip pieces slide on the mounting rod. The abutting block is installed on the side of the mounting rod away from the mounting plate. The tension spring is sleeved on the mounting rod. One end of the tension spring abuts against the abutting block, and the other end abuts against the clip piece away from the mounting plate.

[0004] However, the above-mentioned edge yarn rack of a computerized flat knitting machine can only manually adjust the tensile force through the tensile force adjustment button before knitting, and cannot automatically change the tensile force of the yarn in real time according to the knitting pattern and the running speed of the machine during knitting. Moreover, after the yarn is broken, the yarn may fly out from the threading hole below the jump rod, and it is necessary to manually find the yarn end that has flown to other places after the break and then thread it through the threading hole, which is rather inconvenient.

[0005] Based on this, the utility model designs an automatic edge yarn rack device to solve the above problems. Summary of the Utility Model

[0006] In view of the above-mentioned drawbacks of the prior art, the utility model provides an automatic edge yarn rack device.

[0007] To achieve the above object, the utility model is realized through the following technical solutions:

[0008] The automatic edge yarn rack device includes a frame body. One end of the upper end of the frame body is rotatably connected to one end of a plurality of fixing blocks. The other end of the fixing block is fixedly connected to one end of a jump rod. The other end of the jump rod is provided with a threading hole. The lower end of the frame body is fixedly connected with a plurality of lead screw stepping motors. And the sliding end of the lead screw stepping motor is hinged to one end of a tension spring. The other end of the tension spring is hinged to the end of the fixing block away from the jump rod. A wire clamping and guiding component for facilitating threading of the yarn through the threading hole after the yarn is broken is connected to the jump rod;

[0009] The wire clamping and guiding component includes a clamping component and a sliding component; the sliding component is connected to the jump rod, and the clamping component and the sliding component are connected;

[0010] A tension sensor is installed between the sliding end of the lead screw stepping motor and the tension spring.

[0011] Furthermore, the clamping assembly includes a micro motor, a clamping plate and a connecting block; the micro motor is fixedly connected to the side wall of one end of the connecting block, and the output end of the micro motor passes through the connecting block and is fixedly connected to the clamping plate, the clamping plate is located in a groove that passes through the middle of the connecting block, and the other end of the connecting block is connected to the sliding assembly.

[0012] Furthermore, the size of the clamping piece is the same as the size of the groove on the connecting block.

[0013] Furthermore, the sliding assembly includes a connecting rod, a sliding block, a clamping block and a threaded pull rod; the threaded pull rod is threadedly connected to one end of the sliding block away from the connecting rod, and one end of the threaded pull rod is rotatably connected to the clamping block.

[0014] Furthermore, the sliding block is slidably connected to the side wall of the jumping rod.

[0015] Furthermore, two ends of the connecting rod are fixedly connected to the sliding block and the connecting block respectively.

[0016] Furthermore, one end of the clamping block facing the jumping rod is arranged as a concave surface matching the outer wall of the jumping rod, and an anti-skid layer is arranged on the concave surface to increase the friction between the clamping block and the jumping rod.

[0017] Furthermore, one end of the connecting block close to the threading hole is fixedly connected to the guide cylinder, and the groove of the connecting block is communicated with the guide cylinder.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. When the tension of the tension spring needs to be adjusted, the system controls the rotation of the screw of the screw stepper motor so that the sliding end of the screw stepper motor slides up and down on the side of the frame to stretch or shrink the tension spring, thereby adjusting the tension of the tension spring. This allows the tension of the yarn to be automatically adjusted according to the weaving pattern during the weaving process, so that the tension during weaving can be intelligent and controllable, thereby achieving a more stable weaving effect for more complex patterns; it can also automatically adjust the tension during weaving for complex patterns, such as one-line ready-made clothes, to reduce the undesirable phenomena of cloth rolling, yarn breaking, etc. caused by inappropriate tension during the weaving process. Improve the stability of weaving complex patterns, improve weaving quality, reduce material loss caused by poor weaving, and reduce labor costs when dealing with undesirable phenomena.

[0020] 2. When the utility model is in use, the clamping piece is in a vertical state. Rotate the threaded pull rod so that the clamping block and the sliding block clamp the jump rod, locking the sliding block on the jump rod. First, pass the yarn through the middle groove of the connecting block and the guiding cylinder, and then through the threading hole below the jump rod. When the yarn breaks, due to the lack of the pulling force of the yarn on the lower end of the jump rod, the contraction of the tension spring will drive the fixed block, thereby driving the jump rod to rotate on the top of the frame. And the tension sensor will detect the change of the instantaneous tension. The system controls the micro motor to start. The micro motor controls the rotation of the clamping piece to clamp the yarn. Then rotate the threaded pull rod so that the clamping block moves outward to loosen the jump rod. Then, the sliding block can be pulled towards one end of the threading hole of the jump rod, driving the guiding cylinder and the yarn to move towards the threading hole at the same time until the guiding cylinder passes through the threading hole, and the broken yarn can be easily pulled out to pass through the threading hole.
