Abstract
Description
Technical Field
[0001] This utility model relates to the field of embroidery machines, and in particular to a small-pitch single-bead mechanism. Background Technology
[0002] Embroidery machines, as key equipment for achieving automated embroidery in the textile industry, play a vital role in modern textile production. With consumers' increasing demands for the aesthetics and personalization of textiles, embroidery techniques are becoming increasingly diversified. Among them, beaded embroidery, as a unique and decorative embroidery method, has received growing attention.
[0003] In beaded embroidery, the bead feeding assembly is one of the core components of the embroidery machine. Its main function is to accurately and stably transport the beads to the designated position to achieve precise bead embedding on the textile. However, existing bead feeding assemblies for embroidery machines have many problems in practical applications, which seriously restricts the development and application scope of beaded embroidery.
[0004] Currently, such as Figure 6 , Figure 7 As shown, common bead feeding assemblies on the market are generally bulky and excessively long. This is mainly due to their unreasonable internal structural design and the insufficient compactness of the layout between components, resulting in the entire bead feeding assembly occupying a large space. During the operation of the embroidery machine, it needs to connect and work in coordination with other textile beading mechanisms. However, due to their excessive width, existing bead feeding assemblies are prone to interference with other mechanisms during the connection process, thus affecting the normal operation and efficiency of the embroidery machine.
[0005] Furthermore, the production of beaded textiles often demands a high degree of flexibility. Flexible production means that during the production process, the embroidery machine's mechanism modules need to be quickly changed according to different order requirements and product designs to achieve different types and styles of beaded embroidery effects. However, the existing bead feeding components, due to their wide width, significantly reduce the adaptability of the machine head module. Changing the mechanism module is not only difficult and time-consuming, but compatibility issues can also lead to unstable module installation, affecting the embroidery quality. Utility Model Content
[0006] The purpose of this invention is to provide a small-pitch single-bead mechanism. By optimizing the shape and positional installation relationship of the components, the bead feeding assembly is arranged more reasonably and the structure is more compact, effectively reducing the space occupied by the bead feeding assembly, especially the axial length of the motor, avoiding interference with other components, and improving the compatibility of the bead feeding assembly with other components.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0008] A small-pitch single-bead mechanism includes a bead selection component, a lifting component, a gold sheet component, and a bead feeding component arranged from top to bottom on a frame. The bead feeding component includes a base plate with a through groove formed on it. A first pulley, a second pulley, and a synchronous belt are installed in the through groove. The first pulley is fixed to the motor shaft of a servo motor, which is fixed to the base plate. The second pulley is connected to a swing arm mechanism that drives the bead feeding clamp to move on a base. The base is fixed to the bottom of a connecting plate, and the upper part of the connecting plate is fixedly connected to the base plate. The swing arm mechanism, the base, and the bead feeding clamp are arranged below the housing of the servo motor.
[0009] By placing the pulleys and belts inside the base plate and the swing arm mechanism, base, and ball feeder clamp below the servo motor housing, the arrangement of the ball feeder assembly is made more reasonable and the structure more compact by changing the shape and position of the components. This effectively reduces the space occupied by the ball feeder assembly, especially the axial length of the motor, and avoids interference with other components, thus improving the compatibility of the ball feeder assembly with other components.
[0010] The present invention is further configured such that: a hollow boss is formed on the connecting plate extending along the motor axis of the servo motor; the height of the hollow boss is much lower than the height of the housing part of the servo motor, so no additional length is added in the motor axis;
[0011] The swing arm mechanism includes a swing arm inserted into a hollow boss. The upper end of the swing arm is fixed with a swing shaft, which is rotatably connected to the hollow boss and one end of the swing shaft is fixedly connected to a second pulley. The lower end of the swing arm is formed with a waist-shaped slot, which is inserted into a roller. The roller is connected to a bead feeding clamp through a wheel axle.
[0012] The servo motor drives the first pulley to rotate, and the first pulley drives the second pulley to rotate via the synchronous belt. The second pulley drives the swing arm to rotate at a certain angle via the swing shaft. The swing arm drives the ball feeder to slide on the base through the action between the waist-shaped slot and the roller. When the servo motor reverses, the ball feeder also moves in the opposite direction to reset.
[0013] The present invention is further configured such that a cover plate is fixed on the outer end face of the through groove, the cover plate can prevent external impurities from entering the through groove, and prevent the excessive amount of garbage in the through groove from affecting the normal operation of the synchronous belt.
[0014] The present invention is further configured such that: a limiting locking component is provided on the outer side of the first pulley, and the limiting locking component is fixed on the motor shaft of the servo motor. The limiting locking component can prevent the first pulley from moving outward or falling off during operation.
[0015] This utility model is further configured such that: the limiting locking assembly includes a clamping part and a locking screw. The clamping part has a round hole and an elongated groove formed thereon, one end of the elongated groove communicating with the round hole. The portions of the clamping part located on both sides of the elongated groove have bolt holes and threaded holes formed thereon. The locking screw passes through the bolt holes and is screwed into the threaded holes. During installation, the round hole is inserted into the motor shaft of the servo motor, and then the locking screw is tightened, thereby reducing the spacing of the elongated groove and deforming the round hole accordingly, thus clamping the motor shaft of the servo motor. During disassembly, the limiting locking assembly can be pulled out from the motor shaft simply by loosening the locking screw, thus facilitating installation and disassembly and simplifying the later maintenance of the ball feeding assembly.
[0016] The outstanding effect of this utility model is:
[0017] Compared with existing technologies, by setting the pulleys and belts inside the base plate and placing the swing arm mechanism, base, and ball feeder below the servo motor housing, the shape and positional installation relationship of the components are changed, making the ball feeder assembly more rationally arranged and the structure more compact. This effectively reduces the space occupied by the ball feeder assembly, especially the axial length of the motor, avoids interference with other components, and improves the compatibility of the ball feeder assembly with other components.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0031] The following is for reference Figures 1 to 5 The present invention will be described as follows:
[0032] A small-pitch single-bead mechanism, such as Figure 1 As shown, it includes a bead selection assembly 1, a lifting assembly 2, a gold sheet component 3, and a bead feeding assembly 4, arranged from top to bottom on the frame. Figures 2-4 As shown, the bead feeding assembly 4 includes a base plate 41, on which a through groove 411 is formed. A first pulley 42, a second pulley 43, and a synchronous belt 44 are installed in the through groove 411. The first pulley 42 is fixed on the motor shaft of the servo motor 45, and the servo motor 45 is fixed on the base plate 41. The second pulley 43 is connected to a swing arm mechanism 48 that drives the bead feeding clamp 46 to move on the base 47. The base 47 is fixed to the bottom of the connecting plate 49, and the upper part of the connecting plate 49 is fixedly connected to the base plate 41. The swing arm mechanism 48, the base 47, and the bead feeding clamp 46 are arranged below the housing of the servo motor 45.
[0033] By placing the pulleys and belts inside the base plate, and placing the swing arm mechanism 48, base 47, and ball feed clamp 46 below the housing of the servo motor 45, the arrangement of the ball feed assembly is made more reasonable and the structure more compact by changing the shape and position of the components. This can effectively reduce the space occupied by the ball feed assembly, especially the axial length of the motor, avoid interference with other components, and improve the compatibility of the ball feed assembly with other components.
[0034] like Figure 4 , Figure 5 As shown, a hollow boss 491 extending along the motor axis of the servo motor 45 is formed on the connecting plate 49; the height of the hollow boss 491 is much lower than the height of the housing part of the servo motor 45, so it will not add extra length in the motor axis.
[0035] The swing arm mechanism 48 includes a swing arm 481 inserted into a hollow boss 491. A swing shaft 482 is fixed at the upper end of the swing arm 481. The swing shaft 482 is rotatably connected to the hollow boss 491 and one end of it is fixedly connected to a second pulley 43. The lower end of the swing arm 481 is formed with a waist-shaped slot 483, which is inserted into a roller 484. The roller 484 is connected to a bead feed clamp 46 through a wheel axle 485.
[0036] The servo motor drives the first pulley 42 to rotate, and the first pulley drives the second pulley 43 to rotate through the synchronous belt 44. The second pulley 43 drives the swing arm 481 to rotate a certain angle through the swing shaft 482. The swing arm drives the bead feeding clamp 46 to slide on the base 47 through the action between the waist-shaped slot 483 and the roller 484. When the servo motor reverses, the bead feeding clamp also moves in the opposite direction to reset.
[0037] like Figure 2 As shown, a cover plate 5 is fixed on the outer end face of the through groove 411. The cover plate 5 can prevent external impurities from entering the through groove and prevent the excessive amount of garbage in the through groove from affecting the normal operation of the synchronous belt.
[0038] The first pulley 42 is provided with a limiting locking component 6 on its outer side. The limiting locking component 6 is fixed on the motor shaft of the servo motor 45. The limiting locking component can prevent the first pulley from moving outward or falling off during operation.
[0039] The limiting locking assembly 6 includes a clamping part 61 and a locking screw 62. The clamping part 61 has a round hole 63 and an elongated slot 64 formed on it. One end of the elongated slot 64 communicates with the round hole 63. The portions of the clamping part 61 located on both sides of the elongated slot 64 have bolt holes 65 and threaded holes 66 formed on them. The locking screw 62 passes through the bolt hole 65 and is screwed into the threaded hole 66. During installation, the round hole is inserted into the motor shaft of the servo motor, and then the locking screw is tightened, thereby reducing the spacing of the elongated slots and deforming the round hole to clamp the motor shaft of the servo motor. During disassembly, the limiting locking assembly can be pulled out from the motor shaft simply by loosening the locking screw, which facilitates installation and disassembly and facilitates the later maintenance of the ball feeding assembly.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
