Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a winding machine head-finding structure. Background Art

[0002] At present, the automatic winding machine generally adopts the yarn library type tube changing unit, and the yarn library is one of the main components. Each yarn library generally has 6 or 9 yarn tube holes. Generally, the hole where the yarn tube has been released is the first hole, and the adjacent hole where the yarn tube is ready to be released is the second hole. When the yarn tube on the winding machine has finished unwinding the yarn, the relevant mechanism drives the yarn library to rotate through one yarn tube hole, and the original second hole is transferred to the first hole to release the yarn tube. The original first hole is vacant, and the winder will add the yarn tube to the vacant hole in time. The specific steps are to first hold the yarn tube to find its thread head, pull out a certain length of yarn and put it into the yarn library suction nozzle, and finally put the yarn tube into the hole. This method of manually finding the head and placing the yarn library suction nozzle is relatively inefficient. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a winding machine head finding structure, which can quickly find the thread end.

[0004] The utility model discloses a winding machine head-finding structure, comprising a chassis, a servo motor is arranged at the middle part of the lower side of the chassis, the rotating shaft of the servo motor passes through the chassis, a yarn storehouse is arranged at the upper side of the chassis, the end of the rotating shaft of the servo motor is connected with the bottom center of the yarn storehouse, yarn tube holes are arranged on the yarn storehouse, the yarn tube holes are distributed on the yarn storehouse along a ring array, the yarn tube holes pass through the yarn storehouse up and down, a support rod is arranged at the bottom of the yarn tube hole, a column is arranged upward at the middle part of the support rod, an air outlet is arranged on the chassis just below one of the yarn tube holes, an air inlet pipe is arranged at the lower side of the air outlet, the air inlet pipe is connected with a high-pressure air pipe, an electromagnetic control valve is arranged on the high-pressure air pipe, and a controller is also included, and the controller is electrically connected with the electromagnetic control valve and the servo motor.

[0005] The principle of the above technical solution is that a yarn tube is placed in the yarn tube hole, and the yarn tube is clamped on the column on the support rod. When wiring is required, the controller controls the electromagnetic control valve to open, and the high-pressure gas enters the air inlet pipe and enters the yarn tube hole directly above the air outlet through the air outlet, blows the thread end out of the yarn tube hole, and then wires are connected. When the yarn on the yarn tube is used up, the controller controls the servo motor to rotate a certain angle so that the next yarn tube hole is aligned with the air outlet.

[0006] Furthermore, a retaining edge is vertically arranged upward at the upper edge of the air outlet, and there is a gap between the upper end of the retaining edge and the bottom of the yarn storage, so that the air leakage between the air outlet and the yarn tube hole is reduced by the retaining edge.

[0007] The utility model provides a winding machine head-finding structure, which has the beneficial effect of being able to quickly blow out the thread ends on the yarn tubes in the yarn tube holes, and then connect the threads. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figures 1 to 5 As shown, the utility model discloses a winding machine head-finding structure, including a chassis 1, a servo motor 2 is arranged at the middle part of the lower side of the chassis 1, a rotating shaft 4 of the servo motor 2 passes through the chassis 1, a yarn storage 5 is arranged on the upper side of the chassis 1, the end of the rotating shaft 4 of the servo motor 2 is connected to the bottom center of the yarn storage 5, a yarn tube hole 11 is arranged on the yarn storage 5, the yarn tube hole 11 is distributed on the yarn storage 5 along a circular array, the yarn tube hole 11 passes through the yarn storage 5 up and down, a support rod 9 is arranged at the bottom of the yarn tube hole 11, a column 10 is arranged upward at the middle part of the support rod 9, an air outlet is arranged on the chassis 1 directly below one of the yarn tube holes 11, an air inlet pipe 7 is arranged at the lower side of the air outlet, the air inlet pipe 7 is connected to the high-pressure air pipe 3, an electromagnetic control valve 8 is arranged on the high-pressure air pipe 3, and a controller is also included, and the controller is electrically connected to the electromagnetic control valve 8 and the servo motor 2.

[0016] The principle of the above technical solution is that a yarn tube is placed in the yarn tube hole 11, and the yarn tube is stuck on the column 10 on the support rod 9. When wiring is required, the controller controls the electromagnetic control valve 8 to open, and the high-pressure gas enters the air inlet pipe 7 and enters the yarn tube hole 11 directly above the air outlet through the air outlet, blows the thread end out of the yarn tube hole 11, and then connects the wire. When the yarn on the yarn tube is used up, the controller controls the servo motor 2 to rotate a certain angle so that the next yarn tube hole 11 is aligned with the air outlet.
