Description

Technical Field

[0001] This utility model belongs to the technical field of single-head embroidery machine parts, specifically relating to a thread holder assembly for a single-head embroidery machine. Background Technology

[0002] A single-head embroidery machine, also known as a single-head stitching machine, is a sewing device that automatically embroiders corresponding patterns on fabric based on input parameters, patterns, and programs. Its main features include: 1. High flexibility: It covers various embroidery needs, including flat embroidery, hat embroidery, and garment embroidery, and can be equipped with accessories such as sequins, towel embroidery, and cord embroidery according to customer needs. 2. Easy operation: A network interface is integrated into the motherboard, enabling batch machine interconnection. Multiple networked machines can be monitored in real time, parameters modified, and patterns transmitted via a PC. 3. Wide applicability: It is widely used for brand logo embroidery, as well as pattern embroidery on clothing, hats, accessories, towels, scarves, handbags, shoes, socks, and other products.

[0003] Miniaturization is one of the development trends of single-head embroidery machines. Through compact design and space optimization, the floor space of single-head embroidery machines has been reduced to 60%-70% of that of traditional models. At the same time, the miniaturized design is well adapted to the home and micro-customization market and the need for mobility.

[0004] Conventional single-head embroidery machines typically use a vertical thread holder assembly. This structure results in a reduction in the overall vertical height of the machine, which is a significant limitation. To avoid the drawback of excessive vertical height in vertical thread holder assemblies, this invention aims to provide a thread holder assembly for a single-head embroidery machine. Utility Model Content

[0005] The purpose of this invention is to provide a thread holder assembly for a single-head embroidery machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A thread holder assembly for a single-head embroidery machine includes a thread holder plate with a plurality of thread holder holes. Hollow thread posts are provided at the thread holder holes, passing through the holes, and a hollow thread tube is connected to the front end of each post. A fixing seat is provided at each hollow thread post, and a detachable thread holder sleeve is provided at the fixing seat. A thread holder sleeve through-hole is provided at the head of the sleeve, through which the hollow thread posts pass.

[0007] Preferably, the wire base plate is provided with a plurality of wire base holes, which are evenly distributed in a trapezoidal array.

[0008] Preferably, the wire base plate is provided with 5 wire base holes.

[0009] Preferably, a spool fixing post is provided at the hollow spool column.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The thread holder assembly of a single-head embroidery machine provided by this utility model adopts a horizontally fixed thread holder structure, which greatly reduces the longitudinal height of the overall thread holder assembly; (2) The thread holder assembly of a single-head embroidery machine provided by this utility model adopts the structure of hollow thread post and hollow thread tube; before entering the embroidery machine head, the embroidery thread passes through the hollow thread post and hollow thread tube in succession, which can organize the path of the embroidery thread and effectively reduce the influence of external factors such as wind on the stability of embroidery thread transportation. (3) The thread holder assembly of a single-head embroidery machine provided by this utility model adopts the structural design of thread drum fixing stake, which can effectively fix the thread drum.
