Description

Technical Field

[0001] This utility model relates to the field of sewing machine accessories technology, specifically a sewing thread spool that integrates the thread bundle and the thread cutter. Background Technology

[0002] The thread spool is a core component of a sewing machine, primarily used to wind and store sewing thread and guide it smoothly to the sewing needle. Traditional thread spools typically only have the core function of winding sewing thread and generally suffer from the following technical problems: No bundled wire structure: The bundled wires on the spool are prone to falling off from the edge of the side plate due to vibration or movement, and each wire needs to be searched for one by one when used next time, which is time-consuming and laborious. No-cutting-thread structure: After the thread is used up, it needs to be cut with external tools such as scissors, which is inconvenient and affects work efficiency; Therefore, there is an urgent need for a sewing spool that integrates thread guiding and instant thread cutting to improve ease of use and thread management efficiency. Utility Model Content

[0003] The first technical problem this invention aims to solve is to provide a sewing spool that integrates thread bundling and cutting, thereby constraining the thread bundle when not in use and solving the problems of easy thread bundle detachment and difficulty in finding thread ends in traditional spools.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A sewing thread spool that integrates bundling and cutting threads includes a vertically arranged spool core, a central hole coaxially opened inside the spool core, and side plates horizontally connected above and below the spool core. Its core improvement lies in the fact that a lead wire groove extending from its edge to its axis is provided on any side plate, and a wire harnessing device is installed on the same side plate at the location of the lead wire groove. The wire harness device includes a reference base mounted horizontally on the side plate, a horizontal rotating shaft fixed to one end of the reference base, a flip base rotatably mounted on the horizontal rotating shaft and capable of flipping up and down around the rotating shaft, a wire harness frame fixed to one end of the flip base, and a wire harness opening located inside the wire harness frame. A wire harness cutout is provided on the top of the wire harness frame and is inclined and communicates with the wire harness opening.

[0005] By adopting the above solution, the sewing thread first falls into the thread guide groove, and then enters the thread bundle opening through the thread bundle incision. This can restrain the loose thread bundle within the thread bundle opening and prevent it from falling off. When it is necessary to find the thread end, it can be pulled out directly from the thread guide groove without having to search through the entire spool, thus solving the problems of thread bundle falling off and difficulty in finding the thread end.

[0006] In a preferred embodiment of a sewing thread spool that integrates the thread bundle and the cutting thread, the thread bundle cut consists of an inclined cut. The thread bundle cut is used to guide the sewing thread into the thread bundle opening. Because the cut is inclined, the sewing thread is less likely to fall off from the thread bundle cut, further improving its ability to restrain the sewing thread.

[0007] In a preferred embodiment of a sewing spool that integrates the thread bundle and the thread cutter, the thread bundle cut consists of two inclined and intersecting cuts, wherein the included angle between the two inclined cuts is an acute angle. The thread bundle cut is used to guide the sewing thread into the thread bundle opening. Because the two cuts are inclined, the sewing thread is less likely to fall off from the thread bundle cut, further improving its ability to restrain the sewing thread.

[0008] In a preferred embodiment of a sewing spool that integrates the bundled thread and the cutter thread, the acute angle formed between the upper end of the bundled thread cut and the upper surface of the bundled thread frame is a chamfer, and the acute angle formed between the lower end of the bundled thread cut and the lower surface of the bundled thread frame is a chamfer; wherein, the chamfer is a rounded corner, which can effectively prevent the sewing thread from being scratched or broken when guided within the bundled thread cut.

[0009] As a preferred embodiment of the integrated sewing thread spool for bundling and cutting, the thread bundling device also includes a vertical rotating shaft fixed to the side plate; the reference base is coaxially rotatably mounted on the vertical rotating shaft, which can realize the rotation of the thread bundling groove in multiple directions, further improving the flexibility of the thread bundling.

[0010] The second technical problem this invention aims to solve is to provide a sewing spool that integrates thread bundle and thread cutter functions, with a thread cutter blade built into the thread guide groove. After using the thread, it can be directly pulled to cut, improving operational efficiency and solving the problem that traditional spools require tools to cut the thread bundle, which affects work efficiency.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: Based on the above scheme, an avoidance groove is provided at the inner end of the lead wire groove, and a horizontally arranged wire cutting blade is fixed in the avoidance groove, wherein the cutting edge of the wire cutting blade faces the lead wire groove.

[0012] By adopting the above solution, after the thread is used up, the thread is pulled out from the inside of the lead wire opening along the lead wire cut. The thread bundle is cut immediately when it comes into contact with the blade of the cutting blade, without the need for additional tools, thus improving operational efficiency. Secondly, the cutting blade is hidden in the avoidance groove to prevent accidental injury.

[0013] In a preferred embodiment of a sewing spool that integrates the bundled thread and the cutter, the width of the cutter blade is greater than the width of the thread guide groove, ensuring that the bundle can be completely cut when it reaches the cutter blade along the thread guide groove.

[0014] The beneficial effects of this utility model are: 1. Prevents loose threads and makes it easy to find threads: The sewing thread first falls into the thread guide groove, and then enters the thread bundle opening through the thread bundle incision. This can restrain loose threads in the thread bundle opening and prevent them from falling out. When you need to find the thread end, you can simply pull it out from the thread guide groove without having to search through the entire spool, thus solving the problems of loose threads and difficult-to-find threads. 2. Instant thread cutting: After using the thread, pull the thread out from the inside of the lead wire opening along the lead wire cut. The thread bundle is cut instantly when it comes into contact with the blade of the thread cutter, without the need for additional tools, thus improving operational efficiency. 3. Flexible adjustment: The reference base can rotate around the vertical axis, and the flip base can flip up and down around the horizontal axis to adapt to different wire angles; 4. Safe and convenient: The chamfered / rounded corner design of the lead wire cut avoids scratching the wire, and the wire cutting blade is hidden in the avoidance groove to prevent accidental injury.
