Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a sequin guiding device for embroidery machines. Background Art

[0002] Embroidery machines, also known as computerized embroidery machines, are the most advanced embroidery machines of our time. They enable traditional hand embroidery to be performed at high speed and efficiency, while also achieving the unattainable requirements of "multi-layered, multifunctional, unified, and perfect" quality. They are electromechanical products that embody a variety of advanced technologies. As computerized embroidery replaces hand embroidery, computerized embroidery machines will become a staple in the embroidery industry.

[0003] Embroidery machines are generally classified by function into the following categories: standard flat embroidery machines, sequin embroidery (also known as gold sequin embroidery), towel embroidery, wrapping embroidery (rope embroidery), laser embroidery, flocking embroidery, cap embroidery, and garment embroidery, as well as high-speed machines. There are also high-end machines with multiple functions, such as three-in-one (flat embroidery + gold sequin embroidery + wrapping embroidery) and four-in-one (flat embroidery + gold sequin embroidery + simple wrapping embroidery + towel embroidery). Embroidery machines can combine loop embroidery, multi-color flat embroidery, gold sequin embroidery, and rope embroidery, and are widely used in embroidery processes such as clothing, curtains, bedding, and handicrafts, with a broad application prospect.

[0004] In the sequin embroidery process, the raw material, sequins, is connected by a connecting string that passes through the center of the sequins, forming a reel structure. The reel is then unrolled and fed to an embroidery machine for processing. During processing, these sequins are inserted into the fabric surface using a needle and a string, which secures them tightly. Therefore, the sequins must lie flat on the fabric to achieve the best embroidery effect. However, since the sequins are not completely fixed when attached to the connecting string and can rotate around the string to a certain angle, during unrolling and transportation, individual sequins can easily rotate to different angles, resulting in them not being perfectly flat when they finally move under the needle. This results in some sequins having a poor embroidery effect, affecting the appearance and quality of the product. Therefore, a sequin guiding mechanism is needed that can adjust all the sequins to a parallel position so that they remain flat when moved to the needle position. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a sequin guiding device for an embroidery machine, which solves the problem in the existing technology that sequins can easily rotate to different angles, resulting in that when they finally move under the needle, they are not necessarily in a flat state, resulting in poor embroidery effect of some sequins, affecting the appearance and quality of the product.

[0006] According to an embodiment of the present utility model, a sequin guide device for an embroidery machine includes a vertically arranged housing, the housing being a vertical cylindrical structure with open upper and lower ends, and a guide channel formed inside the housing, the guide channel including a guide section and a limit section sequentially distributed from top to bottom, wherein the guide section is shaped like a trapezoidal funnel structure with the same width at the top and bottom and a thickness gradually decreasing from top to bottom, and the limit section is a flat structure with a cross-sectional shape corresponding to the shape of the lower end of the guide section, thereby forming a through-type structure with a cross-sectional area sequentially decreasing downwardly;

[0007] The top of the guide section is also provided with several groups of sequin straightening mechanisms, which are arranged in parallel in the vertical direction. The sequin straightening mechanisms detect the orientation of the sequins passing through the guide section, and straighten the sequins that are not adapted to the flat direction of the limiting section to be parallel to the limiting section, so that they can just pass through the limiting section.

[0008] Furthermore, the guide section is of an inwardly concave structure, and its inner side surface is an inwardly convex arc surface, and the curvature gradually decreases from top to bottom.

[0009] Furthermore, a cleaning brush is provided in the limiting section. The cleaning brush is symmetrically arranged on the inner wall of the limiting section on both sides of the corresponding sequins, and the cleaning brush is arranged to be tilted downward.

[0010] Furthermore, the sequin straightening mechanism includes a detection component and a correction component. The detection component is arranged at the top entrance of the guide section and is used to detect the azimuth angle of the sequins. The correction component is arranged below the detection component and is used to correct the sequins to a state parallel to the limiting section. The detection component is electrically connected to the correction component.

[0011] Furthermore, the detection component includes a detection brush horizontally arranged at the top of the guide section, and the detection brush includes a number of bristles with a flexible structure, and the bristles are arranged around the inner wall of the guide section. The detection brush is provided with an opening at the position corresponding to the limiting section, and no bristles are provided at the opening position. A pressure sensor is provided at the connection between the bristles and the guide section.

[0012] Furthermore, the correction component includes a plurality of air jets arranged around the central axis of the guide section. The air jets are buried in the inner wall of the guide section so that their air jet directions are horizontally toward the middle of the guide section.

[0013] Furthermore, an air supply pipe is embedded in the shell, and the air supply pipe is arranged around and connected to each air jet port respectively. The air supply pipe is also connected to the air pump through the air inlet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model has a guide section and a limit section distributed in sequence from top to bottom, wherein the guide section is shaped like a trapezoidal funnel structure, and sequins can enter the guide section at any angle, and then be adjusted to a state parallel to the limit section by the sequin straightening mechanism in the guide section, and then leave the limit section, so that all sequins become parallel to each other in sequence after passing through the shell, and thus move to the needle position in a flat state, thereby obtaining the best embroidery fixing effect, and improving the fixing quality and aesthetics.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, an embodiment of the utility model proposes a sequin guiding device for an embroidery machine, comprising a vertically arranged shell 1, which is arranged correspondingly to a position on one side of the needle of the embroidery machine, so that the sequins that leave the shell 1 and are straightened can directly enter the position below the needle for embroidery processing, avoiding rotation again during movement, resulting in changes in the angle of the sequins.

[0023] like Figure 2 As shown, the shell 1 is a vertical cylindrical structure with open upper and lower ends, and a guide channel 2 is formed inside the shell 1. The guide channel 2 includes a guide section 21 and a limit section 22 distributed sequentially from top to bottom, wherein the guide section 21 is shaped like a trapezoidal funnel structure with the same width at the top and bottom and a thickness gradually decreasing from top to bottom. The limit section 22 is a flat structure, and its cross-sectional shape corresponds to the shape of the lower end of the guide section 21, thereby forming a through-type structure with a cross-sectional area that decreases downward.

[0024] Specifically, the guide section 21 is a concave structure, and its inner side is an inwardly convex arc surface, and the arc gradually decreases from top to bottom. The arc structure can reduce the friction between the edge of the sequin and the inner wall of the guide section 21, reducing the probability of sequins getting stuck and causing damage.

[0025] Preferably, a cleaning brush 7 is further provided in the limiting section 22. The cleaning brushes 7 are symmetrically arranged on the inner wall of the limiting section 22 on both sides of the corresponding sequins, and the cleaning brushes 7 are arranged to face downward. The cleaning brushes 7 can further straighten the sequins, keep them vertical, and prevent them from tilting horizontally, so that they can be laid flat under the needle more smoothly.

[0026] like Figure 3 As shown, in this embodiment, the top of the guide section 21 is further provided with two sets of sequin straightening mechanisms. These sequin straightening mechanisms are arranged in parallel along the vertical direction. They detect the orientation of sequins passing through the guide section 21 and straighten any sequins that do not align with the flat orientation of the limiting section 22 until they are parallel to the limiting section 22, allowing them to pass through the limiting section 22. The sequin straightening mechanisms include a detection component and a correction component. The detection component is located at the top entrance of the guide section 21 and is used to detect the orientation angle of the sequins. The correction component is located below the detection component and is used to correct the sequins to be parallel to the limiting section 22. The detection component and the correction component are electrically connected.

[0027] like Figure 4 As shown, the detection assembly further includes a detection brush 3 horizontally arranged at the top of the guide section 21. The detection brush 3 includes a plurality of flexible bristles 31, which are arranged around the inner wall of the guide section 21. The detection brush 3 is provided with an opening 32 at the position corresponding to the limit section 22, and the bristles 31 are not provided at the position of the opening 32. A pressure sensor is provided at the connection between the bristles 31 and the guide section 21. It should be noted that the maximum spacing between the inner ends of the bristles 31 is less than the diameter of the sequins, so that the sequins will definitely touch the bristles 31 without passing through the opening 32.

[0028] Correspondingly, the correction assembly includes several jets arranged around the central axis of the guide section 21. These jets are embedded in the inner wall of the guide section 21, with their jets directed horizontally toward the center of the guide section 21. An air supply pipe 5 is embedded in the housing 1, surrounding and connected to each jet. The pipes 5 are also connected to an air pump via an air inlet 6. The pump supplies high-pressure gas to the jets through the pipes 5. A switch is provided at the jets to limit the release of high-pressure gas.

[0029] In this embodiment, a pressure sensor is electrically connected to the switch of the air jet, controlling its opening and closing. When a sequin falls vertically and passes through opening 32, it is said to correspond precisely to the shape of the limiting section 22, requiring no correction. If a sequin passes by the location of bristles 31 and touches bristles 31, the pressure sensor corresponding to that bristle 31 receives an electrical signal, which in turn controls the opening of the adjacent air jet below that bristle 31, releasing high-pressure gas that rotates the sequin until it is parallel to the limiting section 22. Because two sets of sequin straightening mechanisms are arranged vertically side by side in this embodiment, the sequin can be adjusted twice to better align it with the limiting section 22, ultimately leaving the housing 1 in a mutually parallel state.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
