Description

Technical Field

[0001] The utility model relates to the technical field of clothing manufacturing equipment, in particular to a timing wire winder. Background Art

[0002] At present, the wire winder used by sewing machines consists of a wire core and a wire winding wheel, etc. Among them, the wire core is tightly sleeved on the wheel shaft of the wire winding wheel. When the wire winding wheel rotates, the wire core rotates accordingly, and the wire winder works normally. Similarly, there are also some devices that specifically wind wool or knitting threads of other materials to produce wire winding rolls of different lengths.

[0003] At present, some automatic wire winding devices, such as a wire winding device for a sewing machine of CN219031328U, control the rotation of the wire shaft through a motor to perform wire winding operations, but cannot control its stop, and at the same time lack a device for tensioning the wire harness. It cannot complete the automatic winding of the wire roll.

[0004] The wire winders on the market use a photoelectric sensor that can be aligned with the wire roll. When the wire harness received by the wire barrel reaches a certain thickness, it will extend between the photoelectric sensors, and the photoelectric sensors will control the motor to stop. However, such a control method will be interfered by ambient light and dust. At the same time, there are many parts placed in the entire wire winder, and the overall weight and manufacturing cost will increase. The most important thing is that the device is not convenient to use. Content of the Utility Model

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality of", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] The following is a detailed description of this utility model in conjunction with the various embodiments shown in the accompanying drawings:

[0025] As Figures 1-3 shown, in this embodiment, a timing wire winder is provided, which includes a housing 1. A circuit board and a motor 9 are fixedly arranged inside the housing 1. A switch 2 is fixedly arranged on the housing 1 in an embedded manner. The circuit board is electrically connected to the switch 2 and the motor 9 respectively. The circuit board is the main component for controlling the start and stop of the motor 9. The rotating shaft 3 of the motor 9 penetrates through the housing 1 and extends outwards. When in use, the rotating shaft 3 is used to install a winding drum, and the rotating shaft 3 rotates to continuously wind the wire harness. The circuit board includes a timing module 8 and an interaction module. After calculating a certain time, the timing module 8 will cut off the power supply of the motor 9. The interaction module is fixedly arranged in the housing 1 in an embedded manner. The interaction module extends to the surface of the housing 1. The interaction module is electrically connected to the timing module 8. The interaction module includes a digital tube display screen 6 and buttons 7. The digital tube display screen 6 is used to display the time calculated by the timing module 8. Specifically, refer to Figure 2 , this utility model has three buttons 7. One of the buttons 7 is used to control the start and stop of the motor 9, and the other two buttons respectively control the increase and decrease of the working duration of the motor. The timing module 8 can optionally use a single-chip microcomputer. After the user sets the time and starts it, the timing module 8 will count down according to the set time. After reaching the preset time, it will cut off the power supply of the motor 9 and pause the rotation of the rotating shaft 3. Therefore, the length of the wire harness received by the winding drum (sleeved on the rotating shaft 3) is more accurate.

[0026] A through hole 10 is provided on one side of the housing 1, which facilitates the power cord to pass through the through hole 10 of the housing 1 and be clamped on the hole wall of the through hole 10 of the housing 1, and the power cord is not easily displaced.

[0027] In this embodiment, the stator of the motor 9 is fixedly connected to the inner wall of the housing 1, that is, the housing of the motor 9 is fixedly connected to the housing 1. A gasket 4 is sleeved on the rotating shaft 3 of the motor 9, and the gasket 4 is in interference fit with the rotating shaft 3. When the rotating shaft 3 rotates, it will also control the rotation of the gasket 4. When the winding drum is sleeved on the rotating shaft 3, the bottom of the winding drum will abut against the housing 1, resulting in wear between the winding drum and the housing 1. After adding the gasket 4, the gasket 4 can support the winding drum. Since the gasket 4 is fixed to the rotating shaft 3, the gasket 4 can support the winding drum to rotate during rotation, avoiding wear and generating unnecessary noise. Optionally, a counterbore 5 extending inward is provided in the housing 1, and the gasket 4 is arranged in the counterbore 5; the counterbore 5 and the gasket 4 are coaxially arranged, and the rotation of the gasket 4 is controlled within the counterbore 5.

[0028] In this embodiment, a tensioner is further installed on the housing 1. The motor 9 is arranged at one end of the housing 1, and the tensioner is arranged at the other end of the housing 1, that is, the motor 9 and the tensioner are relatively arranged at both ends of the housing 1 respectively. The set distance can keep the wire harness tight and facilitate wire cutting. The reserved distance can make the wire winding more stable and reduce the amplitude.

[0029] Specifically, the tensioner includes a guide post 11. A retaining piece 12 and a spring 13 are sleeved on the guide post 11. The retaining piece 12 is sleeved at the bottom of the guide post 11. After the spring 13 is sleeved on the guide post 11, it abuts against the retaining piece 12. External threads are provided at the top of the guide post 11, and an adjusting nut 14 is threadedly connected to the top of the guide post 11. When the tensioner guides the wire, the wire will move up and down during the winding process around the winding drum. Therefore, the tensioner needs to be able to buffer these up and down impulses. Both ends of the spring 13 abut against the adjusting nut 14 and the retaining piece 12 respectively. The retaining piece 12 can rely on the spring 13 to make elastic changes up and down with the adjusting nut 14 for buffering. By compressing the spring 13, a part of the impulse from the wire harness movement is offset. It is worth mentioning that the elongation of the spring 13 can be adjusted by rotating the adjusting nut 14 to adjust the elastic force of the spring to correspond to wire harnesses with different amplitudes and impulses.

[0030] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. For those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
