Description

Technical Field

[0001] This invention belongs to the technical field of embroidery equipment, specifically relating to a hot rhinestone machine. Background Technology

[0002] Existing hot rhinestone machines are mostly single-color machines. To achieve multi-color hot rhinestones, multiple automatic rhinestone feeding components and color-changing mechanisms are needed. However, if each automatic rhinestone feeding component requires a separate drive motor, the cost would obviously increase significantly. Referring to Chinese utility model patent CN211546894U, a novel hot rhinestone color-changing mechanism is disclosed. This mechanism is mounted on a frame and includes a suction nozzle fixed to the frame. Opposite the suction nozzle is a material tray conversion structure, which includes a color-changing motor, a large turntable connected to the output shaft of the color-changing motor, and an arc-shaped guide rail on the large turntable. Five equally spaced bearing plates are fixed on the arc-shaped guide rail, each bearing plate having a screw-connected material tray seat, on which a material tray is fixed. A guide post is provided on the arc-shaped guide rail, and the bearing plates have grooves that mate with the guide post. Arc-shaped bearings are installed in the grooves to mate with the arc-shaped guide rail. However, each material tray on the large turntable requires a separate rotating motor to rotate the material tray. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a multi-color automatic drilling component and its single-motor driven drilling structure, thereby solving the problem of high cost caused by each automatic drilling component requiring a separate drive motor in existing technologies.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A single-motor driven drilling structure for a multi-color automatic drilling component includes at least two automatic drilling components arranged side-by-side along the X direction. The multi-color automatic drilling components move along the X direction to achieve color changing. Each automatic drilling component includes a drilling sorting ring that rotates around the X-axis. The single-motor driven drilling structure includes a drilling sorting ring drive motor, a first rotating component driven to rotate by the drilling sorting ring drive motor, and a second rotating component that drives the drilling sorting ring to rotate. The first rotating component drives the second rotating component to rotate. The first rotating component and the second rotating component move relative to each other along the X direction during color changing to achieve separation and transmission connection.

[0005] Preferably, the first rotating component is a first gear, and the second rotating component is a second gear.

[0006] Preferably, a belt drive assembly is provided between the drill-sorting ring drive motor and the first gear.

[0007] Preferably, the first gear is mounted on the first gear shaft, and the belt drive assembly includes a driven pulley mounted on the first gear shaft, a driving pulley mounted on the output shaft of the drill sorting ring drive motor, and a drive belt connecting the driving pulley and the driven pulley.

[0008] Preferably, the drill sorting ring is coaxially fixed with a third gear, and the second gear meshes with the third gear.

[0009] Preferably, the multi-color automatic drill feeding component is slidably mounted on the front side of the drill head fixed seat via the drill head guide rail, and the drill sorting ring drive motor is mounted on the rear side of the drill head fixed seat.

[0010] Preferably, a transmission seat is installed on the rear side of the machine head fixing seat, and the second rotating component is installed on the transmission seat.

[0011] Preferably, the transmission seat is L-shaped, including a vertical section and a horizontal section, wherein the vertical section is fixed to the rear side of the machine head fixing seat, the rear end of the horizontal section is connected to the lower end of the vertical section, and the front end extends forward below the machine head fixing seat. A through groove is provided between the lower end of the vertical section and the middle of the horizontal section, and the second rotating member is located on the side of the front end of the horizontal section.

[0012] Preferably, the drill-row drive motor is mounted on a motor mount, and the motor mount is connected to a transmission mount.

[0013] The present invention also provides a multi-color automatic drill feeding component, including the single-motor driven drill column structure.

[0014] The present invention adopts the above technical solution and has the following technical effects: The multi-color automatic rhinestone feeding component has at least two automatic rhinestone feeding components arranged side by side along the X direction. Each automatic rhinestone feeding component can feed rhinestones of one color. The multi-color automatic rhinestone feeding component moves along the X direction to achieve color changing. In this way, multiple automatic rhinestone feeding components can feed rhinestones alternately, thereby achieving multi-color rhinestone feeding and thus achieving multi-color hot-fix rhinestones.

[0015] The automatic drill feeding component includes a drill sorting ring that rotates around the X-axis. It employs a single-motor driven drill array structure, using only one drill sorting ring drive motor. During each color drill feeding, the drill sorting ring drive motor drives the drill sorting ring of one of the automatic drill feeding components. This drive motor in turn drives a first rotating component to rotate, and a second rotating component drives the drill sorting ring to rotate. The first rotating component then drives the second rotating component. During color changes, the first and second rotating components move relative to each other along the X-axis to achieve separation and transmission connection. This eliminates the need for a separate drill sorting ring drive motor for each automatic drill feeding component, reducing the number of motors and significantly lowering costs.

[0016] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0019] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0020] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," "rear," "X-direction," and "Y-direction," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] like Figures 1 to 11 As shown, the automatic hot-drill machine includes a machine head, which includes a machine head fixing base 500 and a multi-color automatic rhinestone feeding and drilling device installed on the machine head fixing base 500. An embroidery frame is located below the machine head fixing base 500, and adhesive tape can be inlaid on the embroidery frame, onto which the rhinestones 201 can be adhered. Here, the horizontal extension direction of the machine head fixing base 500 is defined as the X-axis, the front-to-back direction as the Y-axis, and the vertical direction as the Z-axis. The embroidery frame can drive the adhesive tape to move horizontally along the X and Y directions.

[0025] The multi-color automatic drill feeding and drilling device includes a multi-color automatic drill feeding component and a suction nozzle component 200. For the multi-color automatic drill feeding component, at least two automatic drill feeding components 100 are arranged side-by-side along the X direction. Each automatic drill feeding component 100 can feed drills of one color (or specification). Multiple automatic drill feeding components can feed drills of multiple colors (or specifications). The multi-color automatic drill feeding component moves along the X direction, aligning one of the automatic drill feeding components 100 with the suction nozzle component 200 to achieve color changing. The other automatic drill feeding component 100, originally aligned with the suction nozzle component 200, is then misaligned. After color changing, the suction nozzle component 200 can then perform vertical drilling.

[0026] Corresponding to the aforementioned multi-color automatic drill feeding component, a color-changing structure can be provided. A color-changing driver can be configured to move the multi-color automatic drill feeding component along the X-direction to achieve color changing. In one embodiment, the color-changing driver includes a color-changing motor and a linear motion mechanism driven by the color-changing motor, wherein the linear motion mechanism drives the multi-color automatic drill feeding component to move along the X-direction. For example, the linear motion mechanism is a screw-nut mechanism, which includes a screw and a nut. The screw is connected to the color-changing motor, and the nut is connected to the multi-color automatic drill feeding component. Alternatively, the linear motion mechanism can also be a gear and rack mechanism, which includes a meshing gear and a rack. The gear is connected to the color-changing motor, and the rack is connected to the multi-color automatic drill feeding component.

[0027] In some embodiments, the automatic drill feeding component 100 includes a drill storage tank 11, a drill sorting ring 12, and a drill sorting ring drive motor 13. The bottom of the drill storage tank 11 has a slot. The drill sorting ring 12 is annular with its axial direction in the X direction. A partial arc portion of the drill sorting ring 12 passes through the slot and is located within the drill storage tank 11. Drill slots 121 are distributed circumferentially on the drill sorting ring 12. The drill sorting ring drive motor 13 drives the drill sorting ring 12 to rotate. During rotation, a partial arc portion of the drill sorting ring 12 always passes through the slot, arranging the drills 201 in the drill storage tank within the drill slots 121. During rotation, after the drills are arranged in the drill slots 121, the drills in the drill slots are conveyed to below the suction nozzle.

[0028] The suction nozzle component 200 is fixed to the inner side of the drill sorting ring 12 and remains stationary in the X direction. When changing colors, after the multi-color automatic drill feeding component moves in the X direction, the suction nozzle component 200 can correspond to one of the automatic drill feeding components 100 in the X direction, thereby cooperating with one of the automatic drill feeding components 100, that is, the automatic drill feeding component 100 delivers the drill 201 below the suction nozzle component 200.

[0029] In this embodiment, the suction nozzle component 200 adopts a vertical drilling structure, including a suction nozzle and a suction nozzle up-and-down driver. The nozzle's mouth faces downward to absorb and release the drill delivered below it by the automatic drill feeding component 100. The suction nozzle up-and-down driver drives the nozzle to move up and down, and its movement path passes through the drill slot 121 during drilling. When the drill sorting ring 12 rotates, delivering the drill 201 in the drill slot 121 directly below the suction nozzle, the nozzle moves downward and absorbs the drill in the drill slot above it. Then, during vertical drilling, the nozzle moves downward, and its movement path continues downward after passing through the drill slot, delivering the drill onto the adhesive paper below. At this time, the suction nozzle releases its suction, allowing the drill to adhere to and remain on the adhesive paper.

[0030] like Figure 5 , Figure 7 and Figure 8 As shown, the suction nozzle has a clearance position, a drill suction position, and a drilling position along its vertical movement direction. The lower end of the suction tube corresponds to the clearance height, drill suction height, and drilling height. When it is necessary to change colors to arrange drills of other colors or sizes, the suction nozzle's up-and-down driver will raise the suction nozzle to the clearance position, with the lower end of the suction tube corresponding to the clearance height, leaving space for the multi-color automatic drill feeding component to move. The multi-color automatic drill feeding component will move to the position of the next color or size automatic drill feeding component under the drive of the color change driver. When it is necessary to suction drills, the suction nozzle's up-and-down driver will raise the suction nozzle to the drill suction position, with the lower end of the suction tube corresponding to the drill suction height. When the drill follows the drill sorting ring 12 and rotates to the lower drill stop 31, the suction nozzle will suck up the drill. When it is necessary to drill, the suction nozzle's up-and-down driver will drive the suction nozzle to move downwards and deliver the drill to the adhesive paper below. The suction nozzle will release the suction force, allowing the drill to adhere to the adhesive paper and remain on the adhesive paper. The suction nozzle will then return to the drill suction position.

[0031] The multi-color automatic rhinestone feeding and drilling device in this embodiment has at least two automatic rhinestone feeding components arranged side-by-side along the X direction. Each automatic rhinestone feeding component can feed one color of rhinestone. The multi-color automatic rhinestone feeding components move along the X direction to change colors. In this way, multiple automatic rhinestone feeding components can alternately feed rhinestones, thereby achieving multi-color rhinestone feeding and thus multi-color hot stamping. It is also easy to achieve matching of four or more colors and specifications, and the matching accuracy can be guaranteed, which can improve the diversity and aesthetics of the pattern.

[0032] Traditional hot-fix rhinestones use a disc-shaped rhinestone arrangement. Referring to Chinese invention patent CN102477670A, the bead storage disc is disc-shaped with a ring of bead grooves near its edge. The disc's axis is perpendicular to the horizontal direction (which has X and Y coordinates), occupying a significant amount of space in the X direction. In this embodiment, the automatic rhinestone feeding component includes a rhinestone sorting ring that rotates around the X direction (X-axis). A motor drives the rhinestone sorting ring to rotate around the X direction. During rotation, the circumferentially distributed rhinestone grooves on the rhinestone sorting ring pass through the rhinestone storage groove, causing the rhinestones in the storage groove to be arranged within the rhinestone grooves. Furthermore, the rotation of the rhinestone sorting ring delivers the rhinestones from the rhinestone grooves to below the suction nozzle. In this way, on the one hand, the traditional disc-shaped rhinestone arrangement is changed to a ring-shaped arrangement, which allows more automatic rhinestone feeding components to be accommodated in the corresponding X-axis space, thus enabling the arrangement of more colors of rhinestones (compared to the traditional disc-shaped rhinestone arrangement, the space for two colors can accommodate four, five, six, or even more colors after the design is changed); on the other hand, the automatic rhinestone feeding components can feed rhinestones continuously, improving the rhinestone feeding efficiency.

[0033] Additionally, the suction nozzle component is relatively fixed in the X direction. When changing colors, the multi-color automatic drill feeding component moves along the X direction, allowing the suction nozzle component to correspond with one of the automatic drill feeding components in the X direction. Therefore, only one suction nozzle component is needed. Corresponding to the design of the drill sorting ring rotating around the X-axis, the suction nozzle component is fixed inside the drill sorting ring. Therefore, each time the drill sorting ring rotates one station (the angle between two adjacent stations and the two adjacent drill slots is the same), a drill can be delivered to the area below the suction nozzle. At the same time, the traditional angle-switching suction drill vertical drilling is replaced with a direct vertical drilling design. The suction nozzle is driven up and down by the suction nozzle up and down driver. When the drill sorting ring delivers the drill directly below the suction nozzle, the suction nozzle moves downward and stops at the suction position above the drill slot, holding the drill in the drill slot. When drilling in the vertical direction, the suction nozzle moves downward, and the movement path of the suction nozzle continues downward after passing through the drill slot, delivering the drill to the adhesive paper below. At this time, the suction nozzle releases the suction force, allowing the drill to adhere to the adhesive paper and remain on the adhesive paper. Compared to traditional angle-switching vertical drilling, this type of drilling machine eliminates the need for angle switching and only requires up-and-down movement, resulting in fewer actions and continuous drilling. Therefore, adopting a vertical drilling structure can improve drilling efficiency by up to 100%.

[0034] Furthermore, by changing the traditional method of directly welding the rhinestones onto the fabric, the rhinestone array is placed on adhesive paper, and the rhinestone heads make soft contact with the adhesive paper, thus solving the mechanical vibration problem and increasing the rotation speed of the rhinestone array ring by several times.

[0035] Therefore, the circular drilling method of the automatic drilling component, combined with the design structure of the suction nozzle component for direct vertical drilling, ensures smooth coordination between drilling and continuous drilling, guaranteeing both drilling efficiency and improving the efficiency of hot-drilling.

[0036] Specifically, for the color-changing structure, the headstock fixing base 500 extends along the X direction, and its front side is provided with a headstock guide rail 51 extending along the X direction. The multi-color automatic drilling component is slidably mounted on the front side of the headstock fixing base 500 via the headstock guide rail 51, and the drill sorting ring drive motor 13 is mounted on the rear side of the headstock fixing base. The multi-color automatic drilling component is mounted on the drilling component bracket 10. The drilling component bracket 10 includes fixing plates 101 on both sides of at least two automatic drilling components 100 arranged side by side along the X direction, fixing beams 102 connecting the two fixing plates 101, and a headstock slider 103 connected to the fixing plates 101. The headstock slider 103 is slidably engaged with the headstock guide rail 51. The fixing plate 101 is provided with a through hole, and the suction nozzle mechanism fixing base 52 extends along the X direction, passing through the through hole and the inner side of the drill sorting ring 12. The two ends of the suction nozzle mechanism fixing base 52 are provided with bent portions, which are fixed to the front side of the headstock fixing base 500. The suction nozzle component 200 is fixed on the suction nozzle mechanism fixing seat 52. The fixing beam 102 is an L-shaped plate, including a horizontal base plate 1021 and a vertical plate 1022 extending vertically upward from the front end of the horizontal base plate. The drilling storage trough 11 is fixed to the vertical plate 1022.

[0037] In some embodiments, a drill-removing member 14 is provided on the radially outer side of the drill sorting ring 12. The drill-removing member 14 is positioned close to the side of the drill sorting ring 12 that rotates away from the drill storage trough 11. In this way, the drills can be arranged in the drill trough and then pass through the drill-removing member 14. When the drill in the drill trough passes through the drill-removing member, if the drill falls into the drill trough correctly, the drill-removing member will not remove the drill from the drill trough. If the drill is in the wrong position in the drill trough, the drill-removing member will remove the drill from the drill trough.

[0038] Preferably, the diamond-removing component 14 is a brush, and the brush contacts the outer circle of the diamond sorting ring. As illustrated in the figure, the diamond sorting ring rotates counterclockwise, and the direction of the brush is opposite to the rotation direction of the diamond sorting ring. The direction of the brush and the radial direction of the corresponding position on the diamond sorting ring form an angle, and the angle is less than or equal to 30 degrees. It is understood that other components, such as silicone or similar materials, can be used to replace the brush as the diamond-removing component.

[0039] Specifically, the upper part of the drill storage tank 11 is rectangular, and the bottom is arc-shaped, with the arc opening facing the rear. Its front view is rectangular, which facilitates the arrangement of more automatic drill feeding components 100 side by side along the X direction. Additionally, a drill flow restrictor 15 is provided inside the drill storage tank 11. The drill flow restrictor 15 is located near the bottom wall of the drill storage tank, and the bottom wall of the drill storage tank is partially arc-shaped corresponding to the outer circle of the drill sorting ring. Correspondingly, the drill flow restrictor 15 is also arc-shaped, forming a flow restricting cavity between it and the bottom wall of the drill storage tank. Flow restricting holes 151 are provided at a certain length of the corresponding slot, allowing some drills in the drill storage tank to enter the flow restricting cavity through the flow restricting holes. This flow restriction facilitates the entry of drills into the drill slot as the drill sorting ring rotates. Furthermore, a drill guard baffle 16 is provided on the outer side of the outer circle of the drill sorting ring. The drill guard baffle 16 is located outside the drill storage tank 11 and extends in an arc shape on the outer side of the outer circle of the drill sorting ring to prevent drills from falling out of the drill slot. The drill guard plate 16 is provided with a drill removal part mounting seat 152, and the brush handle can be fixed in the mounting groove of the drill removal part mounting seat 152 by screws.

[0040] Understandably, an inner support bushing 123 can be provided inside the multi-color automatic drill feeding component. The inner support bushing 123 passes through the multi-color automatic drill feeding component, and its two ends are connected to the fixing plates 101 on both sides of the drill feeding component bracket 10. The drill sorting ring 12 is rotatably supported by the inner support bushing 123. The inner support bushing 123 has a suction nozzle guide groove below the suction nozzle, and the suction nozzle moves up and down and passes through the suction nozzle guide groove.

[0041] In some embodiments, the nozzle up-and-down driver includes upper and lower guide rails 26 and a nozzle drive motor 29. The nozzle is slidably connected to the upper and lower guide rails, and the nozzle drive motor 29 drives the nozzle to move up and down along the upper and lower guide rails 26. The output shaft of the nozzle drive motor is connected to a rocker arm 28, and the nozzle is connected to an up-and-down moving block 27. The rocker arm 28 is movably connected to the up-and-down moving block 27. The up-and-down moving block 27 is provided with a movable groove 271, and the rocker arm 28 is connected to a rotating component 281, such as a bearing. The rotating component is located in the movable groove. When the rocker arm swings, the rotating component moves in the movable groove and drives the up-and-down moving block to move up and down.

[0042] Specifically, the suction nozzle includes a suction tube 21 and a buffer spring 23 connected to the suction tube. The buffer spring 23 provides cushioning when the suction tube 21 moves up and down. This is mainly because when drilling, the drill adsorbed by the suction tube comes into contact with the adhesive tape, which can cause some impact. The buffer spring provides cushioning to avoid impact on the suction tube. This flexible contact between the drill and the adhesive tape also solves the problem of mechanical vibration. The suction nozzle also includes a connector 24 and a guide sleeve 22. The upper end of the guide sleeve 22 is connected to the connector 24, and the upper part of the suction tube 21 moves through the guide sleeve 22. The upper part of the suction tube 21 has a flange. The lower end of the buffer spring 23 is connected to the flange, and the upper end is connected to the lower end of the connector. Additionally, the connector 24 has a lateral interface for connecting to an air pipe to control the suction nozzle. The upper end of the connector is connected to the upper and lower sliders 25 via a screw and a locking nut. The upper and lower sliders 25 slide against the upper and lower guide rails 26, and are fixed to the upper and lower moving blocks 27.

[0043] Furthermore, an air pressure sensor is installed on the suction nozzle to detect the air pressure in the nozzle and determine whether the nozzle is holding the drill. When the nozzle holds the drill, the drill sorting ring 12 stops rotating, and the nozzle passes through the drill slot to deliver the drill. If the nozzle fails to hold the drill, the drill sorting ring 12 continues to rotate until it holds the drill. This self-detection ensures that the pattern on the adhesive tape is perfectly intact.

[0044] In some embodiments, a lower drill stop assembly 300 may be provided, comprising a lower drill stop 31 located below the suction nozzle. Each lower drill stop 31 below the suction nozzle is connected along the X-direction to form a single unit. The lower drill stop 31 has a groove 311 corresponding to the position of the drill sorting ring. Because the gap between the lower drill stop 31 and the drill sorting ring is small, and the drill bit protrudes slightly from the drill slot, the groove 311 facilitates the rotation and passage of the drill sorting ring. The lower drill stop 31 has a blocking state and a yielding state. In the blocking state, the lower drill stop blocks the space below the suction nozzle and is located below the drill slot of the drill sorting ring. In the yielding state, the lower drill stop clears space below the suction nozzle, allowing the drill to pass through the drill slot and be lowered. The lower drill stop 31 is positioned directly opposite the drill slot to be suctioned, preventing the drill from falling out of the drill slot before the suction nozzle holds it, thus improving the success rate of drill suction.

[0045] To drive the movement of the drill stop bar, the drill stop bar 31 is connected to a front and rear drive unit. The front and rear drive unit includes front and rear guide rails and a drill stop bar drive motor 35. The drill stop bar drive motor 35 drives the drill stop bar 31 to move back and forth along the front and rear guide rails. When transitioning from a drill-stopping state to a clearance state, the front and rear drive units drive the drill stop bar 31 to move backward, exposing the drill discharge slot 121. Specifically, a transmission assembly is provided between the drill stop bar drive motor 35 and the drill stop bar 31. The transmission assembly includes front and rear racks 32 and a fourth gear 33. The front and rear racks 32 are connected to the drill stop bar 31, and the front and rear racks 32 mesh with the fourth gear 33. Additionally, a rear mounting beam 104 is connected to the bottom rear side of the two side mounting plates 101. The rear mounting beam 104 is located behind the headstock 500. A rotating shaft 34 is provided between the two side rear mounting beams and the bottom connection part of the mounting plate 101. One end of the rotating shaft is located outside the bottom connection part of the rear mounting beam and the mounting plate 101 and is connected to the fourth gear 33. The other end of the rotating shaft is connected to the output shaft of the down-drilling stop drive motor 35 through the second belt drive assembly 36. The second driven pulley in the second belt drive assembly 36 is fixed on the rotating shaft 34. Front and rear guide rails can be set on the lower side of the two side mounting plates 101.

[0046] like Figure 9 and Figure 10 As shown, in some embodiments, each automatic drill feeding component is equipped with a drill sorting ring drive motor 13 to drive the drill sorting ring 12, which can be referred to as a multi-motor driven drill array structure. Figure 2 As shown, for the multi-motor driven drilling structure, the drill ring drive motors 13 are located behind the headstock 500 and can be mounted on the rear mounting beam and headstock via motor brackets. Due to space limitations, they are not arranged side-by-side in a straight line, but rather adjacent drill ring drive motors 13 are staggered. A second gear 18 is rotatably mounted on the rotating shaft corresponding to each drill ring. A first belt drive assembly 17 is provided between the second gear 18 and the corresponding drill ring drive motor 13. The first driven pulley in the first belt drive assembly 17 is fixed side-by-side with the second gear 18, thus the drill ring drive motor 13 drives the second gear 18 to rotate via the first belt drive assembly 17. A third gear 122 is coaxially fixed to the drill ring 12. The second gear 18 meshes with the third gear 122, so the rotation of the second gear drives the rotation of the third gear 122, and the drill ring 12 rotates synchronously with the third gear 122.

[0047] The automatic hot-drill machine works by pouring drills into the drill storage tank 11, and the automatic drill feeding component operates. The drill sorting ring drive motor 13 drives the drill sorting ring 12 to rotate counterclockwise. When the drill sorting ring 12 rotates, the drills 201 poured into the drill storage tank 11 will automatically fall into the drill discharge groove 121 of the drill sorting ring 12 due to their own weight. When the drills in the discharge groove 121 follow the rotation of the drill sorting ring 12, they pass the drill removal part 14. If the drill falls into the discharge groove 121 correctly, it will not be brushed off. Otherwise, it will be brushed off and wait for the next drop. This can effectively ensure that the drills discharged by the drill sorting ring 12 have a consistent surface.

[0048] When the drill follows the drill sorting ring 12 and rotates to the lower drill stop 31, the suction nozzle will hold the drill and prepare to drill. At this time, the front and rear drivers of the lower drill stop 31 drive the lower drill stop 31 to move backward, exposing the drill slot 121. Then, the upper and lower drivers of the suction nozzle drive the suction nozzle to move downward and send the drill out onto the adhesive paper below. The suction nozzle releases the suction force, allowing the drill to stick to the adhesive paper and stay on the adhesive paper. The suction nozzle returns to the drill holding position. At this time, the embroidery frame with the adhesive paper will move one position according to the design requirements to prepare for placing the next drill.

[0049] When it is necessary to change the color of the drills to other colors or specifications, the suction nozzle up and down driver will raise the suction nozzle to the top, i.e., the clearance position, to make room for the automatic drill feeding component 100 to move. The automatic drill feeding component 100 will move to the position of the drill storage tank 11 of the next color or specification under the drive of the color changing mechanism.

[0050] Repeat the above steps according to the design to leave beautiful patterns on the adhesive tape.

[0051] like Figure 11 As shown, in some embodiments, a single-motor driven drilling structure can also be used, with only one drilling ring drive motor 13. The single-motor driven drilling structure includes a first rotating component driven to rotate by the drilling ring drive motor 13 and a second rotating component that drives the drilling ring to rotate. The first rotating component drives the second rotating component to rotate, and during color change, the first rotating component and the second rotating component move relative to each other in the X direction to achieve separation and transmission connection.

[0052] Here, the first rotating component is a first gear 194, and the second rotating component is a second gear 18. The second gear is configured in the same way as in the above-described implementation where each automatic drilling component is equipped with a drill sorting ring drive motor 13 to drive the drill sorting ring 12. A third belt drive assembly is provided between the drill sorting ring drive motor 13 and the first gear 194. The first gear 194 is mounted on the first gear shaft, and the third belt drive assembly includes a third driven pulley mounted on the first gear shaft, a third driving pulley mounted on the output shaft of the drill sorting ring drive motor, and a third drive belt connecting the third driving pulley and the third driven pulley. Therefore, the first gear 194 is fixed in the X direction. During color change, the multi-color automatic drilling component moves in the X direction, and the second gear of one automatic drilling component separates from the first gear. After color change, the second gear of the other automatic drilling component is connected to the first gear. It is understood that the first and second rotating components can also be replaced by other rotating components.

[0053] like Figure 2 As shown, to facilitate the installation of the aforementioned third belt drive assembly and the drill ring drive motor, a transmission seat 19 is installed on the rear side of the machine head fixing seat. The transmission seat 19 is L-shaped, including a vertical section 191 and a horizontal section 192. The vertical section is fixed to the rear side of the machine head fixing seat, the rear end of the horizontal section is connected to the lower end of the vertical section, and the front end extends forward below the machine head fixing seat. A through groove 193 is provided between the lower end of the vertical section and the middle of the horizontal section. The second gear 18 is located on the side of the front end of the horizontal section, the third driven pulley is located inside the through groove 193, and the third drive belt is also located inside the through groove 193. The drill ring drive motor 13 is installed on the motor seat 131, and the motor seat 131 is connected to the transmission seat. The motor seat includes a front section, a rear section, and a middle section. The drill ring drive motor is installed on the side of the rear section, and the front section extends along the X direction and is connected to the transmission seat.

[0054] During each color drill feeding, the drill sorting ring drive motor drives the drill sorting ring of one of the automatic drill feeding components. This drive motor in turn rotates a first rotating component, which in turn rotates a second rotating component, which in turn drives the drill sorting ring. During color changes, the first and second rotating components move relative to each other along the X-axis to achieve separation and transmission connection. This eliminates the need for a separate drill sorting ring drive motor for each automatic drill feeding component, reducing the number of motors and significantly lowering costs.

[0055] In the above embodiments, whether it is a multi-motor driven drilling structure or a single-motor driven drilling structure, the rotating shaft not only serves to install the second gear, but also acts as part of the lower drill stop assembly 300, used to install the fourth gear 33 and the second driven pulley in the second belt drive assembly 36.

[0056] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art should understand that the invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the invention will be included within the scope of the claims.
