Description

Technical Field

[0001] This utility model relates to the field of textile tool technology, and in particular to a bobbin tube that can eliminate inertia. Background Technology

[0002] Textile coils are widely used in embroidery and sewing of textiles. The bobbin is a support tube located at the center of the textile spool. When used in sewing devices, it is usually placed inside the bobbin case and can rotate inside the bobbin case. When the sewing device pulls the thread out of the bobbin, the bobbin and the coil will rotate at high speed inside the bobbin case to cooperate with the thread release. When the bobbin is rotating at high speed in the bobbin case, if the sewing device suddenly stops pulling the thread, the bobbin and the coil will rotate several more times due to inertia, causing the thread to entangle inside the bobbin case. This can easily cause the bobbin thread to knot or become tangled and blocked inside the bobbin case. Pulling the thread out in this way can cause jamming and lead to the bobbin thread breaking. To solve this problem, some existing products embed ferrite magnets. The magnetic attraction between the magnet and the bobbin case eliminates the inertia generated by the high-speed rotation of the bobbin inside the bobbin case.

[0003] The existing method of braking the bobbin by embedding ferrite magnets has high production costs and the process of embedding ferrite magnets is complicated. Due to the small size of the bobbin and the ferrite magnets, the assembly and manufacturing difficulty of the bobbin is further increased. Utility Model Content

[0004] This invention provides a bobbin tube that can eliminate inertia, solving the problems of high production costs and cumbersome embedding process of existing bobbin tubes that rely on embedding ferrite magnets for braking, and the increased assembly and manufacturing difficulty of the bobbin tube due to the small size of the bobbin tube and ferrite magnet.

[0005] This utility model provides a bobbin tube that can eliminate inertia, specifically including: a bobbin tube body, an outer ring groove is formed on the left edge of the outer surface of the bobbin tube body, a magnetic sleeve is tightly fitted into the outer ring groove, and the magnetic sleeve is made of plastic injection molding mixed with ferrite magnetic powder.

[0006] Furthermore, the outer annular groove surface is provided with two strip-shaped annular groove directional protrusions, which are axially symmetrically distributed in the outer annular groove surface with the axis of the bobbin tube body as the axis.

[0007] Furthermore, the directional ridge of the annular groove is parallel to the axis of the bobbin tube body, and the two ends of the directional ridge of the annular groove are connected to the right groove surface of the outer annular groove and the left end surface of the bobbin tube body, respectively.

[0008] Furthermore, the inner right edge of the magnetic sleeve is machined with an inner chamfer, and two sleeve orientation slots with strip-shaped groove structures are opened on the inner wall of the magnetic sleeve. The two sleeve orientation slots are symmetrically distributed on the inner wall of the magnetic sleeve with the axis of the magnetic sleeve as the axis, and the sleeve orientation slots are fitted with the annular groove orientation protrusions.

[0009] Furthermore, the right end of the tube sleeve directional slot is provided with a flared slot insertion opening, which is connected to the right end face of the magnetic tube sleeve.

[0010] Furthermore, the left end of the magnetic tube sleeve is internally folded to form a sleeve end flange, which is attached to the left end face of the bobbin tube body.

[0011] This invention provides a bobbin tube that can eliminate inertia, which has the following beneficial effects:

[0012] The bobbin tube in this invention is assembled in two sections. A magnetic sleeve made of plastic mixed with ferrite magnetic powder is fixedly sleeved to the bobbin tube body, making one end of the bobbin tube magnetic. When the bobbin tube rotates at high speed inside the bobbin case, after the textile equipment stops drawing the yarn, the magnetic attraction between the magnetic sleeve and the inside of the bobbin case brakes the bobbin tube, preventing it from continuing to rotate under inertia and causing the bobbin thread to coil or knot. Compared with the existing technology that uses embedded ferrite magnets, this reduces the amount of ferrite magnets used, thus saving costs.

[0013] In this invention, the magnetic sleeve is tightly fitted onto the outer ring groove. During the assembly of the bobbin tube, the slot is aligned with the directional protrusion of the ring groove, and the magnetic sleeve is pushed to the right to ensure it is tightly fitted onto the outer ring groove. The alignment of the sleeve's directional slot with the directional protrusion of the ring groove improves the installation tightness of the magnetic sleeve and maintains the installation angle of the magnetic sleeve. Compared with the existing technology that uses embedded ferrite magnets, the assembly method is faster and more secure. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example: Please refer to Figures 1 to 6 :

[0027] This invention proposes a bobbin tube that can eliminate inertia, comprising: a bobbin tube body 1, with an outer annular groove 2 formed on the left edge of the outer surface of the bobbin tube body 1, and a magnetic sleeve 3 tightly fitted into the outer annular groove 2. The magnetic sleeve 3 is made of plastic injection molded with ferrite magnetic powder 305. By connecting the bobbin tube body 1 and the magnetic sleeve 3, the magnetic effect of the ferrite magnetic powder 305 causes the bobbin tube to rotate at high speed inside the bobbin case. After the textile equipment stops drawing the yarn, the magnetic attraction between the magnetic sleeve 3 and the inside of the bobbin case generates braking on the bobbin tube, preventing the bobbin tube from continuing to rotate under inertia and causing the bobbin thread to wind or knot. Compared with the existing technology that uses embedded ferrite magnets, this invention greatly reduces the amount of ferrite magnets used and also avoids the situation where ferrite magnets fall off and damage the bobbin tube.

[0028] In this embodiment, two strip-shaped annular groove directional protrusions 201 are provided on the surface of the outer annular groove 2. These two protrusions 201 are axially symmetrically distributed on the surface of the outer annular groove 2, with the axis of the bobbin tube body 1 as the axis. The annular groove directional protrusions 201 are parallel to the axis of the bobbin tube body 1. The two ends of the annular groove directional protrusions 201 are connected to the right surface of the outer annular groove 2 and the left end face of the bobbin tube body 1, respectively. An inner chamfer 301 is machined on the right edge of the inner surface of the magnetic sleeve 3. The design of the inner chamfer 301 facilitates the assembly of the magnetic sleeve 3 with the outer annular groove 2. Two strip-shaped slots 302 are provided on the wall. The two slots 302 are symmetrically distributed on the inner wall of the magnetic sleeve 3 with the axis of the magnetic sleeve 3 as the axis. The slots 302 fit into the annular groove 201. The right end of the slot 302 is provided with a flared slot 303. The slot 303 connects to the right end face of the magnetic sleeve 3. The flared design of the slot 303 facilitates the precise docking of the slots 302 and the annular groove 201 during the docking of the magnetic sleeve 3 and the outer annular groove 2.

[0029] The left end of the magnetic sleeve 3 is folded inward to form a sleeve end flange 304, which fits against the left end face of the bobbin body 1. The magnetic sleeve 3 is tightly fitted onto the outer ring groove 2. When assembling the bobbin, the slot insertion 303 is aligned with the ring groove orientation protrusion 201, and the magnetic sleeve 3 is pushed to the right to fit tightly onto the outer ring groove 2. The alignment of the sleeve orientation slot 302 with the ring groove orientation protrusion 201 can improve the installation tightness of the magnetic sleeve 3 and maintain the installation angle of the magnetic sleeve 3, making the bobbin structure compact and the outer surface flat in the assembled state.

[0030] The working principle of this embodiment is as follows: First, one end of the magnetic sleeve 3 in the bobbin tube is placed towards the inside of the bobbin case and inserted into the bobbin case. The bottom thread of the yarn is threaded into the textile machine. When the machine pulls the yarn, the yarn spindle rotates at high speed inside the bobbin case. When the textile machine stops pulling the yarn, the magnetic attraction between the ferrite magnetic powder 305 inside the magnetic sleeve 3 and the bobbin case causes the end face of the magnetic sleeve 3 to be tightly attached to the metal bobbin case, generating friction. The friction brakes the bobbin tube, preventing the coil from continuously rotating under inertia and causing the yarn to become entangled and block the bobbin case. This also prevents the bobbin case from being unable to rotate due to jamming when pulling the yarn again.
