Description

Technical Field

[0001] This application relates to the field of textile equipment, and more specifically, to an electric bobbin drawing device. Background Technology

[0002] When the bobbin thread is almost used up, common sewing equipment removes the excess thread from the bobbin and rewinds it to ensure sewing quality and avoid problems such as uneven stitches, thread breaks, and thread jams caused by excess thread residue on the bobbin.

[0003] Existing bobbin thread removal devices typically use pneumatic methods to extract excess thread. However, high-pressure gas sources have uncertainties, such as insufficient oil and water filtration leading to unstable machine operation. Instable gas pressure can also cause unstable machine operation, reducing the machine's lifespan.

[0004] Therefore, a new bobbin thread removal device is needed to solve the above problems. Utility Model Content

[0005] The advantage of this application lies in providing an electric bobbin drawing device, which uses a vacuum motor to create negative pressure inside the storage box, thereby drawing excess thread from the bobbin into the storage box through the drawing tube. This ensures the stability of the drawing process and machine operation, effectively extending the service life of the equipment. At the same time, by setting up a filter, the device effectively prevents excess thread and dust from being drawn out of the storage box to the outside during the negative pressure formation process, ensuring the cleanliness of the machine's working environment.

[0006] Other advantages and features of this application will become apparent from the following description and can be realized by means and combinations particularly pointed out in the specification.

[0007] To achieve at least one of the above advantages, this application provides an electric bobbin drawing device, including a drawing tube, a storage box, and a negative pressure device. The drawing tube is disposed on the storage box and connected to the storage box, through which excess thread on the bobbin is drawn into the storage box. The negative pressure device includes a vacuum motor and a filter. The air intake of the vacuum motor is disposed inside the storage box, and the exhaust port of the vacuum motor is disposed outside the storage box. The filter is disposed inside the storage box and sleeved outside the air intake of the vacuum motor.

[0008] In a bobbin electric drawing device according to this application, the storage box is provided with an opening and closing door.

[0009] In a bobbin electric drawing device according to this application, a support rod is provided inside the storage box, and the support rod is supported below the filter.

[0010] In a bobbin electric drawing device according to this application, the filter is a dust filter cartridge.

[0011] In a bobbin electric drawing device according to this application, a thread-removing fixing mechanism is further included. The thread-removing fixing mechanism is disposed above the drawing tube and is used to fix the bobbin so that it rotates to draw the thread.

[0012] In a bobbin electric drawing device according to this application, a limiting mechanism is further included, which is disposed between the drawing tube and the bobbin fixing mechanism.

[0013] In a bobbin electric drawing device according to this application, the limiting mechanism includes two limiting members, and a limiting gap is provided between the two limiting members, through which the excess thread enters the drawing tube.

[0026] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0027] like Figure 1 As shown, an electric bobbin thread drawing device according to an embodiment of this application is illustrated. The electric thread drawing device includes a drawing tube 1, a storage box 2, and a negative pressure device 3. The drawing tube 1 is disposed on and connected to the storage box 2, and excess thread on the bobbin is drawn into the storage box 2 through the drawing tube 1. Further, the storage box 2 is provided with an opening and closing door 21. When the opening and closing door 21 is closed, negative pressure operation can be performed through the negative pressure device 3. After thread drawing is completed, the opening and closing door 21 can also be opened to collect excess thread and clean the storage box 2.

[0028] like Figure 2 and Figure 3 As shown, the negative pressure device 3 includes a suction motor 31 and a filter 32. The suction port 311 of the suction motor 31 is located inside the storage box 2, and the exhaust port 312 of the suction motor 31 is located outside the storage box 2. The filter 32 is located inside the storage box 2 and is fitted over the suction port 311 of the suction motor 31. In this way, during the negative pressure formation process, the suction motor 31 effectively prevents residual wires and dust inside the storage box 2 from being drawn out to the outside, ensuring the cleanliness of the machine's working environment.

[0029] Preferably, the filter 32 is a dust filter cartridge, but it can also be configured as other devices that filter the gas entering the exhaust port 311. This application does not make any specific limitations.

[0030] Furthermore, the storage box 2 is provided with a support rod 22, which is supported below the filter.

[0031] Specifically, the electric thread-drawing device also includes a thread-removing and fixing mechanism 4, which is disposed above the thread-drawing tube 1 and is used to fix the bobbin so that it rotates to draw the thread.

[0032] Furthermore, the electric wire drawing device also includes a limiting mechanism 5, which is disposed between the wire-removing fixing mechanism 4 and the wire-drawing tube 1.

[0033] Specifically, the limiting mechanism 5 includes two limiting members 51, with a limiting gap 52 between the two limiting members 51. The excess wire enters the drawing tube 1 through the limiting gap 52. The limiting mechanism 5 restricts the position of the excess wire, ensuring that the excess wire can enter the drawing tube 1 faster and more accurately.

[0034] In summary, this application provides an electric bobbin drawing device that uses the vacuum motor 31 to create negative pressure inside the storage box 2, thereby drawing excess thread from the bobbin into the storage box 2 through the drawing tube 1. This ensures the stability of thread drawing and machine operation, effectively extending the service life of the equipment. Simultaneously, by incorporating the filter 32, the device effectively prevents excess thread and dust from being drawn from the vacuum motor 31 into the outside environment during the negative pressure formation process, ensuring the cleanliness of the machine's working environment.
