Description

Technical Field

[0001] The present invention relates to the technical field of embroidery, and particularly relates to a thread control mechanism, an embroidery system and an embroidery process. Background Art

[0002] With the increasing demand of consumers for embroidery diversity and quality, hollow embroidery and terry embroidery are more and more widely used in the embroidery field. Among them, the embroidery products based on the hollow embroidery process have a soft and comfortable user experience. At present, for the existing hollow embroidery process, for example, a three-dimensional embroidery method and a three-dimensional embroidery product disclosed in a Chinese invention patent with the publication number of CN111235782A, it is necessary to set a water-soluble fabric layer on the fabric to be embroidered, and embroider in the area corresponding to the water-soluble fabric layer. After the embroidery is completed, the water-soluble fabric layer is dissolved by chemical liquid to form a soft hollow embroidery product. However, this embroidery process does not meet the environmental protection requirements and will cause pollution to water resources.

[0003] In addition, the existing terry embroidery process in the market is realized by a simple terry embroidery device. However, during the embroidery process of the existing terry embroidery device, loops can only be formed in one direction. Such a terry embroidery method is suitable for the case where the embroidery product is relatively square. For more complex flower patterns, the effect is very poor, and the embroidery efficiency is also very low, and the mechanical failure rate is high, which cannot meet the market demand and has a poor market acceptance.

[0004] The applicant's prior patent application provides a thread control device and an embroidery system. Among them, the thread control device includes a thread control disk and a thread control disk driving mechanism for driving the thread control disk to rotate. A plurality of thread control parts are evenly arranged along the circumferential direction on the outer periphery of the thread control disk. The thread control part includes a needle position groove with an opening and a thread loop support arm located radially outside the needle position groove. For the thread control device with the above structure, during the embroidery process, a thread loop can be formed through the thread loop support arm, so that a three-dimensional terry embroidery or hollow embroidery can be embroidered, changing the traditional processes of terry embroidery and hollow embroidery. The system has a high function integration degree, a relatively high embroidery efficiency, and a better three-dimensional texture of the embroidery product.

[0005] However, for the thread control device with the above structure, for the formed thread loop, a relatively complex thread loop holding mechanism is required to prevent the thread loop from being pulled out, which makes the structure and control mode of the thread control device more complex. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a thread control mechanism, an embroidery system and an embroidery process. Among them, relying on the structural optimization of the thread control disk in the thread control mechanism, the technical problem of how to hold the thread loop is solved. There is no need to set a thread loop holding mechanism, making the structure of the thread control mechanism more concise and the cost lower.

The wire loop support arm of each wire control part extends along the circumferential direction and crosses the opening of the needle position groove of the adjacent wire control part. A wire passing gap communicating with the opening is arranged on the inner side of the wire loop support arm.

[0008] In a preferred embodiment, the wire loop support arm includes a first support section located radially outside the needle position groove, a second support section extending below the wire loop support arm of the adjacent needle position groove, and a bending section connecting the first support section and the second support section.

[0010] In a preferred embodiment, the outer surface of the wire loop support arm is smoothly arranged.

[0011] In a preferred embodiment, the wire control disc driving mechanism at least includes a driving motor and a transmission mechanism arranged between the driving motor and the wire control disc.

[0012] In a preferred embodiment, the transmission mechanism includes a driving pulley connected to the output shaft of the driving motor, a driven pulley coaxially connected to the wire control disc, and a transmission belt located between the driving pulley and the driven pulley.

[0013] In a preferred embodiment, it further includes a cover for accommodating the wire control disc. The cover is provided with a wire control position. An embroidery needle groove longitudinally penetrating the cover is arranged at the wire control position. The radially outer side of the embroidery needle groove is open. The cover is also provided with a radially opening groove communicating with the open part of the embroidery needle groove at the wire control position.

[0014] An embroidery system of this embodiment at least includes:

[0015] A machine head, on which a needle bar holder is arranged, and a plurality of embroidery needles are arranged on the needle bar holder;

[0016] A wire control mechanism;

[0017] A color changing mechanism, the color changing mechanism includes a color changing guide rail fixedly connected to the needle bar holder and a slider slidably matched with the color changing guide rail. The extending direction of the color changing guide rail is the same as the arrangement direction of the embroidery needles;

[0018] The wire control frame, the wire control frame at least includes a base, a first bracket and a second bracket. The wire control mechanism is installed on the base. The first bracket is fixedly connected to the base. A displacement driving mechanism is arranged between the first bracket and the second bracket. The second bracket is fixedly connected to the slider;

[0019] The wire control disc includes a wire control working position below the sewing needle and a non-wire control working position far from below the sewing needle. The displacement driving mechanism is used to drive the wire control disc to move between the wire control working position and the non-wire control working position.

[0020] In a preferred embodiment, the displacement driving mechanism includes a lead screw, a lead screw motor arranged on the second bracket, and a lead screw nut adapted to the lead screw. The lead screw is arranged obliquely relative to the vertical direction. The first bracket is linked with the lead screw nut. A guiding mechanism is arranged between the first bracket and the second bracket.

[0021] In a preferred embodiment, the guiding mechanism includes a guiding groove arranged on the second bracket and a guiding part arranged on the first bracket and adapted to the guiding groove; the guiding groove includes an inclined guiding section parallel to the lead screw and a vertical guiding section connected to the lower end of the inclined guiding section.

[0022] In a preferred embodiment, it further includes a third bracket connected to the lead screw nut. A transverse guiding mechanism is arranged between the third bracket and the first bracket.

[0023] An embroidery process using the embroidery system in this embodiment at least includes the following steps:

[0024] Step A: The sewing needle is at the high position. The wire control disc rotates until one of the needle position grooves is in the piercing direction of the sewing needle. The embroidery thread is basically in a vertical state between the sewing needle and the fabric, and the embroidery thread is located outside the wire loop support arm;

[0025] Step B: The sewing needle moves downward to the lowest position. The embroidery thread surrounds the wire loop support arm outside the needle position groove and the wire loop support arm of the previous wire control part and forms a wire loop. This wire loop is sleeved on the two wire loop support arms;

[0026] Step C: The sewing needle moves upward to the highest position. The wire control disc rotates until the next needle position groove is in the piercing direction of the sewing needle. During the rotation of the wire control disc, the wire loop disengages from the wire loop support arm of the previous wire control part and is sleeved on the wire loop support arm corresponding to the needle position groove in Step B;

[0027] Step D: The sewing needle moves downward to the lowest position. The embroidery thread surrounds the wire loop support arm outside the needle position groove and forms a new wire loop. In this state, the two wire loops are respectively sleeved on the two wire loop support arms;

[0028] Step E: The sewing needle moves upward to the highest position, and the thread control disc rotates to the next needle position groove which is in the puncture direction of the sewing needle. During the rotation of the thread control disc, the thread loop in Step C disengages from the corresponding thread loop support arm, and the thread loop formed in Step D remains on the thread loop support arm corresponding to the previous needle position groove;

[0029] The above Steps D - E are reciprocally cycled until the embroidery is completed.

[0030] In a preferred embodiment, during the reciprocating cycle of Steps D - E, the thread control mechanism can also be controlled to move up and down in the vertical direction to form thread loops at different heights.

[0031] The thread control mechanism, embroidery system and embroidery process of this embodiment have the following

[0032] Beneficial effects:

[0033] (1) During the embroidery process, thread loops can be formed through the thread loop support arms, so that three - dimensional terry embroidery or hollow embroidery can be embroidered, changing the traditional processes of terry embroidery and hollow embroidery. The system has a high degree of function integration, high embroidery efficiency, and better three - dimensional texture of the embroidered product.

[0034] (2) The thread loop support arms of each thread control part extend along the circumferential direction and cross the openings of the needle position grooves of the adjacent thread control parts. During the formation of a new thread loop, the thread loop support arm of the previous thread control part plays a role in holding and supporting the previous thread loop. By optimizing the structure of the thread control disc itself, the technical problem of how to hold the thread loop is solved, and there is no need to set up an additional thread loop holding mechanism, making the structure of the thread control mechanism more concise and the cost lower.

[0035] (3) The thread control mechanism can be used as an accessory and installed on the head of the existing embroidery machine, so that the existing embroidery machine can realize the hollow embroidery and terry embroidery processes by installing this accessory, and the application scenario is more extensive.

[0036] (4) The rotatably arranged thread control disc can form thread loops in any direction, and the styles of embroidered products that can be realized are more diverse.

[0037] (5) Through the color - changing mechanism, the thread control disc can work at different sewing needle positions, so as to embroider embroidered products of multiple colors.

[0038] (6) By the lifting step of the thread control mechanism, thread loops at different heights are formed, making the embroidered product more layered. Description of the Drawings
