Description

Technical Field

[0001] This invention relates to the field of embroidery technology, and more specifically to an embroidery technique. Background Technology

[0002] As consumers demand greater diversity and quality in embroidery, hollow embroidery and terry embroidery are increasingly used in the embroidery industry. Hollow embroidery, in particular, offers a soft and comfortable user experience. Current hollow embroidery techniques, such as the three-dimensional embroidery method and finished product disclosed in Chinese invention patent CN111235782A, require setting a water-soluble fabric layer on the fabric to be embroidered, and then embroidering in the corresponding areas. After embroidery, the water-soluble fabric layer is dissolved using chemicals, resulting in a soft hollow embroidery product. However, this embroidery process does not meet environmental protection requirements and can pollute water resources.

[0003] Furthermore, the existing terry embroidery technique on the market is achieved through a simple terry embroidery device. However, the existing terry embroidery device can only form loops in one direction during the embroidery process. This type of terry embroidery method is suitable for relatively square embroidered products. For more complex patterns, the effect is very poor, and the embroidery efficiency is also very low. The machine failure rate is also high, which cannot meet the market demand and has poor market acceptance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an embroidery process for embroidering hollow embroidery and terry embroidery, so as to overcome the defects of hollow embroidery and terry embroidery techniques in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an embroidery process, comprising at least the following steps:

[0006] Step A: The needle is positioned high, and the embroidery thread is basically vertical between the needle and the fabric;

[0007] Step B: Move the embroidery thread to the outside of the loop support arm through the loop support arm, with the needle piercing in the inside of the loop support arm;

[0008] Step C: The needle moves downward to the lowest position, and the embroidery thread wraps around the loop support arm to form a loop;

[0009] Step D: The needle moves from the lowest position to the highest position, and the loop support arm disengages from the loop;

[0010] The above steps are repeated in a loop.

[0011] In a preferred embodiment, the thread loop support arm is disposed on the thread control disc, the thread control disc is rotatably disposed, and a plurality of thread control parts are evenly distributed along the circumferential direction on the outer periphery of the thread control disc. Each thread control part includes a needle position groove with an opening and a thread loop support arm located radially outside the needle position groove.

[0012] In a preferred embodiment, the cross-sectional perimeter of the loop support arm gradually decreases from the bottom of the needle slot towards the opening, and the outer surface of the loop support arm is smoothly disposed.

[0013] In a preferred embodiment, the method further includes a color-changing step, wherein the control position of the control disc switches between different needles.

[0014] In a preferred embodiment, the thread control disc includes a thread control working position located below the needle and a non-thread control working position located away from the needle, and the displacement driving mechanism is used to drive the thread control disc to move between the thread control working position and the non-thread control working position.

[0015] In a preferred embodiment, the method further includes a lifting and lowering step of the control panel in the control working position.

[0016] In a preferred embodiment, the device further includes a loop retaining mechanism comprising an elastic pressure plate, the elastic pressure plate including a retaining working position abutting against the outer side of the loop support arm and a non-retaining working position away from the radial opening slot.

[0017] In a preferred embodiment, the loop retaining mechanism further includes a cylinder and a support arm for driving the elastic pressure plate to move between a retaining working position and a non-retaining working position, one end of the support arm being connected to the cylinder and the other end being connected to the elastic pressure plate.

[0018] Compared with the prior art, the embroidery system and embroidery machine of this embodiment have the following advantages:

[0019] (1) During the embroidery process, the thread loop support arm can form a thread loop, which can then be used to embroider a three-dimensional terry embroidery or hollow embroidery. This changes the traditional terry embroidery and hollow embroidery process. The system has a high degree of functional integration, higher embroidery efficiency, and better three-dimensional texture of the embroidery.

[0020] (2) By changing the color, the control disc can work at different needle positions, thus producing embroidery in a variety of colors.

[0021] (3) The rotating control disc can form thread loops in any direction, making the embroidery styles more diverse.

[0022] (4) By raising and lowering the control plate at the control position, different heights of thread loops are formed, making the embroidery more layered. Attached Figure Description

[0045] The embroidery system used in the embroidery process of this embodiment, such as... Figure 1A , Figure 1B As shown, it includes a machine head, a thread control mechanism, a color changing mechanism, and a thread control frame 40. Among them, the machine head is provided with a needle bar frame 60, on which a number of machine needles 61 are arranged side by side.

[0046] like Figure 5 , Figure 6As shown, the cable control mechanism in this embodiment includes a cable control disk 10 and a cable control disk drive mechanism 20, wherein the cable control disk 10 is rotatably configured with respect to... Figure 7 The enclosure shown. As a special feature of this embodiment, as...

Each control part includes a needle groove 11 with an opening 12 and a thread loop support arm 13 located radially outside the needle groove 11.

[0047] In this embodiment, as Figure 6 As shown, the cover 14 is provided with a thread control position, and a needle embroidery groove 15 is provided in the thread control position, which extends longitudinally through the cover. The needle embroidery groove 15 is open on the radially outer side. The cover is also provided with a radially open groove 16 at the thread control position, which communicates with the open part of the needle embroidery groove 15. In the thread control working position, the needle embroidery groove is located in the piercing direction of the needle.

[0048] In this embodiment, the control disk driving mechanism 20 includes a stepper motor 21 for driving the control disk to rotate and a transmission mechanism located between the stepper motor 21 and the control disk 10. Preferably, the transmission mechanism is as follows: Figure 5 As shown, the drive belt includes a driving pulley 23 connected to the output shaft of the stepper motor 21, a driven pulley 24 coaxially connected to the control disc 10, and a transmission belt 22 located between the driving pulley and the driven pulley. It should be noted that belt drive is only a preferred embodiment of this configuration; other transmission structures from the prior art can also be used.

[0049] In this embodiment, since there are multiple needles, a special color-changing mechanism is designed to allow the thread control mechanism to work with each needle for embroidery, i.e., to achieve color changing. Figure 1A , Figure 1B As shown, the device includes a color-changing guide rail 62 fixedly connected to the needle bar frame 60 and a slider 63 slidably engaged with the color-changing guide rail 62. The thread control mechanism is linked to the slider 63, and the extension direction of the color-changing guide rail 62 is the same as the arrangement direction of the needles 61. It should be noted that color-changing mechanisms are widely used in the embroidery field, and their specific structure will not be described in detail in this embodiment.

[0050] The structure of the control frame 40 in this embodiment is as follows: Figures 2-5 As shown, the system includes a base 41, a first bracket 42, a second bracket 43, and a third bracket 44. The control mechanism is mounted on the base 41, the first bracket 42 is fixedly connected to the base 41, and the second bracket 43 is fixedly connected to the slider 63, thereby enabling the control mechanism and the slider to move in tandem.

[0051] As a special feature of this embodiment, a displacement driving mechanism 50 is provided between the first bracket 42 and the second bracket 43 for driving the control line mechanism. Figure 1A The control line working position shown is Figure 1B The movement between the non-control line workstations shown.

[0052] Preferably, the displacement driving mechanism in this embodiment is as follows: Figure 2-5 As shown, the system includes a lead screw 52 mounted on the second bracket 43, a lead screw motor 51, and a lead screw nut 53 adapted to the lead screw. Preferably, in this embodiment, the lead screw 52 is inclined relative to the vertical direction, the first bracket 52 is linked with the lead screw nut 53, and a guide mechanism is provided between the first bracket 42 and the second bracket 43.

[0053] A preferred guidance mechanism, such as Figure 9-12 As shown, the guiding mechanism includes a guide groove disposed on the second bracket 43 and a guide portion 421 disposed on the first bracket and adapted to the guide groove. In this embodiment, the guide groove includes an inclined guide section 431 parallel to the lead screw 52 and a vertical guide section 432 connected to the lower end of the inclined guide section.

[0054] In this embodiment, based on the cooperation of the displacement driving mechanism 50 and the guiding mechanism, the control line mechanism in Figure 1A The control line working position shown is Figure 1B The movement between the non-controlling working positions is shown. The vertical guide section 432 allows the control mechanism to move up and down in the controlling working position. To accommodate the up and down movement of the control mechanism in the controlling working position, a transverse guide mechanism is provided between the third support 44 and the first support 42. Specifically, in this embodiment, the transverse guide mechanism includes a transverse guide groove 422 disposed on the first support 42 and a transverse guide rail 441 disposed on the third support 44 that is adapted to it. When the guide part 421 moves within the inclined guide section 431, the third support 44 and the first support 42 move as a whole; when the guide part 421 moves within the vertical guide section 432, the third support 44 moves laterally relative to the first support 42.

[0055] The embroidery system of this embodiment also includes a thread loop retaining mechanism 30, such as... Figure 8 As shown, the loop retaining mechanism 30 includes an elastic pressure plate 31, which includes... Figure 14 The holding position shown is located at the radial opening slot and is used to abut against the outer side of the loop support arm. Figure 13The non-holding working position is shown away from the radial opening slot. Preferably, in this embodiment, the loop retaining mechanism further includes a cylinder 33 and a support arm 32 for driving the elastic pressure plate to move between the holding working position and the non-holding working position. One end of the support arm is connected to the cylinder, and the other end is connected to the elastic pressure plate.

[0056] The embroidery process in this embodiment includes the following steps:

[0057] Step A: As Figure 13 As shown, the needle is positioned high, and the embroidery thread is basically vertical between the needle and the fabric.

[0058] Step B: Rotate the thread control disc to move the embroidery thread to the outside of the thread loop support arm. The needle's piercing direction is located inside the thread loop support arm. Specifically, in this embodiment, the needle's piercing direction is located in the needle embroidery groove.

[0059] In this embodiment, before step B, such as Figure 14 As shown, cylinder 33 drives elastic pressure plate 31 to move to the holding working position.

[0060] Step C: The needle moves downwards to the lowest position, as shown. Figure 15 As shown, the embroidery thread is wrapped around the thread loop support arm to form a thread loop 120.

[0061] Step D: The needle moves from the lowest position to the highest position, the control disc 10 rotates, and the loop support arm exits from the loop, forming a loop.

[0062] By repeating the above steps A and D, we can obtain... Figure 16-18 The terry embroidery and hollow embroidery shown are examples of terry embroidery.

[0063] In order to facilitate the retraction of the loop support arm 13 from the loop 120, the cross-sectional perimeter of the loop support arm gradually decreases from the bottom of the needle slot to the opening, and the outer surface of the loop support arm is smoothly disposed.

[0064] In this embodiment, the function of the thread loop holding mechanism is to clamp the thread loop with the elastic pressure plate and the thread loop support arm to prevent the thread loop from being pulled during the winding process, thereby ensuring the quality of the terry embroidery or hollow embroidery.

[0065] In this embodiment, due to the vertical guide section 432, the line control mechanism can move up and down vertically in the line control working position, thus forming line loops of different heights, for example... Figure 17 The varying heights of the terry embroidery shown make the embroidery more layered and textured.

[0066] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
