Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0033] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0034] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "front", "back", "X direction", "Y direction", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0038] like Figures 1 to 11 As shown, the automatic hot drilling machine includes a machine head, which includes a machine head fixing seat 500, a multi-color automatic drill feeding and drilling device installed on the machine head fixing seat 500, and an embroidery frame is arranged below the machine head fixing seat 500, on which adhesive tape can be inlaid, and the drill 201 can be bonded to the adhesive tape. Here, the lateral extension direction of the machine head fixing seat 500 is set as the X direction, the front and rear direction is the Y direction, and the up and down direction is the Z direction. The embroidery frame can drive the adhesive tape to move horizontally along the X direction and the Y direction.

[0039] The multi-color automatic drill feeding and drilling device comprises 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 realize the delivery of drills of one color (or specification), and multiple automatic drill feeding components can realize the delivery of drills of multiple colors (or specifications). The multi-color automatic drill feeding component moves along the X direction, and one of the automatic drill feeding components 100 is made to correspond to the position of the suction nozzle component 200 to realize color change, and the other automatic drill feeding component 100 originally corresponding to the position of the suction nozzle component 200 is staggered with the position of the suction nozzle component 200. After the color change is completed, the suction nozzle component 200 can be corresponding to the vertical direction drilling.

[0040] A color-changing structure is provided corresponding to the above-mentioned multi-color automatic drill delivery component, and a color-changing driver can be provided to drive the multi-color automatic drill delivery component to move along the X direction to achieve color change. 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 delivery component to move along the X direction. For example, the linear motion mechanism is a screw-nut mechanism, and the screw-nut mechanism 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 delivery component. Alternatively, the linear motion mechanism can also be a gear rack mechanism, and the gear rack mechanism 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 delivery component.

[0041] In some embodiments, the automatic drill feeding component 100 includes a drill storage trough 11, a drill sorting ring 12, and a drill sorting ring driving motor 13. The bottom of the drill storage trough 11 is provided with a slot, the drill sorting ring 12 is annular, and its axial direction is in the X direction. The local arc portion of the drill sorting ring 12 passes through the slot and is located in the drill storage trough 11. The drill sorting ring 12 is provided with drill row slots 121 distributed along the circumference, and the drill sorting ring driving motor 13 drives the drill sorting ring 12 to rotate. During the rotation process, the drill sorting ring 12 always has a local arc portion passing through the slot, and the drills 201 in the drill storage trough are arranged in the drill row slot 121, and during the rotation process of the drill sorting ring 12, after the drills are arranged in the drill row slot 121, the drills in the drill row slot are transported to the bottom of the suction nozzle.

[0042] The nozzle component 200 is relatively fixed to the inner side of the drill sorting ring 12 and relatively fixed in the X direction. When changing colors, after the multi-color automatic drill delivery component moves along the X direction, the nozzle component 200 can correspond to one of the automatic drill delivery components 100 in the X direction, thereby cooperating with one of the automatic drill delivery components 100, that is, the automatic drill delivery component 100 delivers the drill 201 to the bottom of the nozzle component 200.

[0043] 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 mouth of the suction nozzle faces downward to absorb the drill sent to the bottom of the suction nozzle by the automatic drill feeding component 100 and release the absorbed drill. The suction nozzle up and down driver drives the suction nozzle to move up and down, and the movement path of the suction nozzle passes through the drill row groove 121 during drilling. When the drill sorting ring 12 rotates and sends the drill 201 in the drill row groove 121 to the bottom of the suction nozzle, the suction nozzle moves downward and sucks the drill in the drill row groove above the drill row groove. Then, 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 row groove, so that the drill can be sent to the adhesive tape below. At this time, the suction nozzle releases the suction force, allowing the drill to adhere to the adhesive tape and stay on the adhesive tape.

[0044] like Figure 5 , Figure 7 and Figure 8 As shown, the suction nozzle has an avoidance position, a drill suction position and a drilling position along the up and down movement direction, and the lower end of the suction pipe of the suction nozzle corresponds to the avoidance height, the drill suction height and the drilling height. When it is necessary to change the color to arrange other colors or specifications of drills, the upper and lower drivers of the suction nozzle will raise the suction nozzle to the avoidance position, and the lower end of the suction pipe will correspond to the avoidance height, leaving a movable space for the multi-color automatic drill delivery component. The multi-color automatic drill delivery component will move to the position of the automatic drill delivery component of the next color or specification under the drive of the color change driver. When it is necessary to suck the drill, the upper and lower drivers of the suction nozzle will raise the suction nozzle to the drill suction position, and the lower end of the suction pipe will correspond to the drill suction height. When the drill follows the drill sorting ring 12 to rotate to the lower drill stop bar 31, the suction nozzle will suck the drill. When drilling is required, the upper and lower drivers of the suction nozzle drive the suction nozzle to move downward to send the drill to the adhesive tape below, and the suction nozzle releases the suction force, allowing the drill to adhere to the adhesive tape and stay on the adhesive tape, and the suction nozzle returns to the drill suction position.

[0045] In the multi-color automatic diamond feeding and drilling device of the present embodiment, the multi-color automatic diamond feeding component is provided with at least two automatic diamond feeding components side by side along the X direction, each automatic diamond feeding component can realize diamond feeding of one color, and the multi-color automatic diamond feeding component moves along the X direction to realize color change, so that multiple automatic diamond feeding components can alternately feed diamonds, thereby realizing multi-color diamond feeding, and then realizing multi-color hot drilling. It is also easy to realize color registration of more than four colors and specifications, and the color registration accuracy can also be guaranteed, which can improve the diversity and aesthetics of the pattern.

[0046] Traditional hot drilling uses a disc drill arrangement design structure. Referring to the Chinese invention patent with publication number CN102477670A, the bead storage plate is a disc-shaped structure, and a circle of bead grooves is arranged near the edge of the bead storage plate. The axis of the bead storage plate is perpendicular to the horizontal direction (having X and Y coordinates in the horizontal direction), and occupies a large space in the X direction. In this embodiment, the automatic drill feeding component includes a drill sorting ring rotating around the X direction (X axis), and the drill sorting ring driving motor drives the drill sorting to rotate around the X direction. During the rotation of the drill sorting ring, the circumferentially distributed drill row grooves on the drill sorting ring pass through the drill storage groove, so that the drills in the drill storage groove are arranged in the drill row groove, and the drills in the drill row groove are transported to the bottom of the suction nozzle during the rotation of the drill sorting ring. In this way, on the one hand, the design structure of the traditional hot drill disc diamond arrangement is changed to a circular diamond arrangement mode, so that more automatic diamond feeding components can be accommodated in the corresponding X-direction space, thereby completing the arrangement of diamonds of more colors (compared with the design structure of the traditional hot drill disc diamond arrangement, the traditional two-color space can accommodate 4 colors, 5 colors, 6 colors, or even more colors after the design structure is changed); on the other hand, the automatic diamond feeding component can continuously feed diamonds, thereby improving the diamond feeding efficiency.

[0047] In addition, the suction nozzle component is relatively fixed in the X direction. When changing colors, after the multi-color automatic drill delivery component moves along the X direction, the suction nozzle component can correspond to one of the automatic drill delivery components in the X direction, so only one suction nozzle component is required. Corresponding to the design that the drill sorting ring rotates around the X axis, the suction nozzle component is fixed on the inner side of the drill sorting ring. Therefore, every time the drill sorting ring rotates one station (the angle between two adjacent stations and two adjacent drill slots is the same), a drill can be sent to the bottom of the suction nozzle. At the same time, the traditional angle switching suction drill vertical drilling is changed to a design structure of direct vertical drilling. The suction nozzle is driven up and down by the suction nozzle up and down drive. When the drill sorting ring sends the drill to the bottom of the suction nozzle, the suction nozzle moves downward and stays at the suction position above the drill slot to suck 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, sending the drill to the adhesive tape below. At this time, the suction nozzle releases the suction force, allowing the drill to adhere to the adhesive tape and stay on the adhesive tape. Compared with the traditional angle-switching suction drill vertical drilling, there is no need to switch angles, only up and down movements, relatively few movements, and continuous drilling. Therefore, the use of a vertical drilling structure can improve drilling efficiency, and the drilling efficiency can be increased by 1 times.

[0048] Furthermore, the traditional method of directly hot-welding the drills on the fabric is changed to arranging the drills on the adhesive tape, and the hot-drill heads and the adhesive tape are in soft contact, which solves the problem of mechanical vibration and increases the rotation speed of the drill sorting ring by several times.

[0049] Therefore, the circular drilling method of the automatic drill feeding component is combined with the design structure of the suction nozzle component for direct vertical drilling. The drill feeding and drilling are coordinated smoothly, and the drill feeding and drilling can be carried out continuously. The drill feeding efficiency and the drilling efficiency can be guaranteed, thereby improving the hot drilling efficiency.

[0050] For the color-changing structure, specifically, the head fixing seat 500 extends along the X direction, and a head guide rail 51 extending along the X direction is provided on the front side thereof, the multi-color automatic drill feeding component is slidably mounted on the front side of the head fixing seat 500 through the head guide rail 51, and the drill sorting ring driving motor 13 is mounted on the rear side of the head fixing seat. The multi-color automatic drill feeding component is mounted on the drill feeding component bracket 10, and the drill feeding component bracket 10 includes a fixing plate 101 provided on both sides of the X direction of at least two automatic drill feeding components 100 arranged side by side along the X direction, a fixing beam 102 connecting the fixing plates 101 on both sides, and a head slider 103 connected to the fixing plate 101, and the head slider 103 is slidably matched with the head guide rail 51. Among them, the fixing plate 101 is provided with a through hole, the suction nozzle mechanism fixing seat 52 extends along the X direction, passes through the through hole and the inner side of the drill sorting ring 12, and the suction nozzle mechanism fixing seat 52 is provided with a bending portion at both ends, and the bending portion is fixed to the front side of the head fixing seat 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 bottom plate 1021 and a vertical plate 1022 extending vertically upward from the front end of the horizontal bottom plate, and the drill storage trough 11 is fixed to the vertical plate 1022.

[0051] In some embodiments, a drill picking member 14 is provided on the radial outer side of the drill sorting ring 12, and the drill picking member 14 is arranged close to the side of the drill sorting ring 12 that rotates away from the drill storage trough 11, so that the drills can be arranged in the drill row groove and then pass through the drill picking member 14. When the drills in the drill row groove pass through the drill picking member, if the drill falls into the drill row groove correctly, the drill picking member will not remove the drill from the drill row groove; if the drill is in the wrong orientation in the drill row groove, the drill picking member will remove the drill from the drill row groove.

[0052] Preferably, the drill picker 14 is a brush, and the brush contacts the outer circle of the drill sorting ring. As shown in the figure, the drill sorting ring rotates counterclockwise, the direction of the brush is opposite to the rotation direction of the drill sorting ring, and there is an angle between the direction of the brush and the radial direction of the corresponding position of the drill sorting ring, and the angle is less than or equal to 30 degrees. It is understandable that other components can be used to replace the brush as the drill picker, such as silicone and other similar materials.

[0053] Specifically, the upper part of the drill storage trough 11 is a rectangular structure, and the bottom part is an arc-shaped structure, with the arc mouth facing the rear side, and its front view is rectangular, so that it is conducive to arranging more automatic drill feeding components 100 side by side along the X direction. In addition, a drill flow limiting plate 15 is provided in the drill storage trough 11. The drill flow limiting plate 15 is arranged near the bottom wall of the drill storage trough, and the bottom wall of the drill storage trough is partially arc-shaped corresponding to the outer circle of the drill sorting ring. Correspondingly, the drill flow limiting plate 15 is also arc-shaped, and a flow limiting cavity is formed between the drill storage trough and the bottom wall, and a flow limiting hole 151 is provided at a part of the length position corresponding to the slot, so that part of the drill in the drill storage trough enters the flow limiting cavity through the flow limiting hole. Through the flow limiting effect, it is conducive to the drill entering the drill row slot when the drill sorting ring rotates. In addition, a drill protection baffle 16 is provided on the outer side of the outer circle of the drill sorting ring. The drill protection baffle 16 is located on the outer side of the drill storage trough 11 and extends in an arc shape on the outer side of the outer circle of the drill sorting ring to prevent the drill from falling off from the drill row slot. A drill picker mounting seat 152 is provided on the drill protection baffle 16 , and a brush handle of the brush can be fixed in a mounting groove of the drill picker mounting seat 152 by screws.

[0054] It is understandable that an inner support bushing 123 can be provided inside the multi-color automatic drill delivery component, the inner support bushing 123 passes through the multi-color automatic drill delivery component, and both ends are connected to the fixing plates 101 on both sides of the drill delivery component bracket 10. The drill sorting ring 12 is rotatably supported by the inner support bushing 123. The inner support bushing 123 is provided with a suction nozzle guide groove corresponding to the lower part of the suction nozzle, and the suction nozzle moves up and down and passes through the suction nozzle guide groove.

[0055] In some embodiments, the nozzle up and down driver includes an upper and lower guide rail 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 swing rod 28, the nozzle is connected to an up and down moving block 27, and the swing rod 28 is movably connected to the up and down moving block 27. The up and down moving block 27 is provided with an active groove 271, the swing rod 28 is connected to a rotating member 281, such as a bearing, and the rotating member is arranged in the active groove. When the swing rod swings, the rotating member moves in the active groove and drives the up and down moving block to move up and down.

[0056] Specifically, the suction nozzle includes a suction pipe 21 and a buffer spring 23 connected to the suction pipe, and the buffer spring 23 provides buffering when the suction pipe 21 moves up and down. Mainly, when drilling, the drill adsorbed by the suction pipe contacts the adhesive tape, which will have a certain impact, and the buffer spring provides buffering at this time to avoid the impact on the suction pipe. In this way, the drill and the adhesive tape adopt a flexible contact method, which can also solve the problem of mechanical vibration. The suction nozzle also includes a joint 24 and a guide sleeve 22, the upper end of the guide sleeve 22 is connected to the joint 24, the upper part of the suction pipe 21 is movably inserted into the guide sleeve 22, the upper part of the suction pipe 21 is provided with 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 joint. In addition, the joint 24 is provided with a lateral interface, which is connected to the air pipe to control the suction nozzle. The upper end of the joint is connected to the upper and lower sliders 25 through a screw and a locking nut, the upper and lower sliders 25 are slidably matched with the upper and lower guide rails 26, and the upper and lower sliders 25 are fixed to the upper and lower moving blocks 27.

[0057] Furthermore, an air pressure sensor is installed on the suction nozzle, and the air pressure of the suction nozzle is detected by the air pressure sensor to determine whether the suction nozzle sucks the drill. When the suction nozzle sucks the drill, the drill sorting ring 12 stops rotating, and the suction nozzle passes through the drill row slot to send the drill out. If the suction nozzle fails to suck the drill, the drill sorting ring 12 continues to rotate until the drill is sucked. In this way, self-detection can ensure that the pattern on the adhesive tape is perfect.

[0058] In some embodiments, a lower drill stop bar assembly 300 may also be provided, and the lower drill stop bar assembly 300 includes a lower drill stop bar 31, and the lower drill stop bar 31 is provided below the suction nozzle, and the lower drill stop bar 31 below each suction nozzle is connected to form a whole along the X direction. The lower drill stop bar 31 is provided with a groove 311 corresponding to the position of the drill sorting ring, because the gap between the lower drill stop bar 31 and the drill sorting ring is small, and the drill will partially protrude from the drill row groove, so the provision of the groove 311 is conducive to the rotation of the drill sorting ring. The lower drill stop bar 31 has a drill blocking state and an avoidance state. In the drill blocking state, the lower drill stop bar is blocked below the suction nozzle and is located below the drill row groove of the drill sorting ring. In the avoidance state, the lower drill stop bar gives up the space below the suction nozzle, and the drill can be put down from the drill row groove. The lower drill stop bar 31 is arranged directly opposite to the drill row groove to be sucked, which can prevent the drill from falling off from the drill row groove before the suction nozzle sucks the drill, thereby improving the success rate of sucking the drill.

[0059] In order to drive the movement of the lower drill stop bar, the lower drill stop bar 31 is connected to a lower drill stop bar front and rear driver, which includes front and rear guide rails and a lower drill stop bar driving motor 35, and the lower drill stop bar driving motor 35 drives the lower drill stop bar 31 to move forward and backward along the front and rear guide rails. When switching from the drill blocking state to the avoidance state, the lower drill stop bar front and rear driver drives the lower drill stop bar 31 to move backward to expose the drill row groove 121. Specifically, a transmission assembly is provided between the lower drill stop bar driving motor 35 and the lower drill stop bar 31, and the transmission assembly includes a front and rear rack 32 and a fourth gear 33, the front and rear rack 32 is connected to the lower drill stop bar 31, and the front and rear rack 32 is meshed with the fourth gear 33. In addition, the rear side of the bottom of the fixed plates 101 on both sides is connected with a rear mounting beam 104, which is located at the rear side of the head fixing seat 500. A rotating shaft 34 is provided between the bottom connecting parts of the rear mounting beams on both sides and the fixed plates 101. One end of the rotating shaft is located outside the bottom connecting part of the rear mounting beam and the fixed plates 101 and is connected to the fourth gear 33. The other end of the rotating shaft is connected to the output shaft of the lower drill stopper driving motor 35 through the second belt transmission assembly 36, wherein the second driven pulley in the second belt transmission assembly 36 is fixed on the rotating shaft 34. The front and rear guide rails can be arranged on the lower side of the fixed plates 101 on both sides.

[0060] like Fig. 9 and Fig.10 As shown, in some embodiments, each automatic drill feeding component is provided with a drill sorting ring driving motor 13 to drive the drill sorting ring 12, which can be referred to as a multi-motor driven drill arrangement structure. Figure 2 As shown, for the multi-motor driven drilling structure, the drilling sorting ring driving motor 13 is located at the rear side of the machine head fixing seat 500, and can be installed on the rear mounting beam and the machine head fixing seat through the motor bracket. Due to space limitations, they are not arranged side by side in a straight line, but two adjacent drilling sorting ring driving motors 13 are staggered. A second gear 18 is installed on the rotating shaft corresponding to each drilling sorting ring rotation, and a first belt transmission assembly 17 is arranged between the second gear 18 and the corresponding drilling sorting ring driving motor 13, wherein the first driven pulley in the first belt transmission assembly 17 is fixed side by side with the second gear 18, so the drilling sorting ring driving motor 13 drives the second gear 18 to rotate through the first belt transmission assembly 17. The drilling sorting ring 12 is coaxially fixed with a third gear 122, and the second gear 18 is meshed with the third gear 122, so the second gear rotates and drives the third gear 122 to rotate, and the drilling sorting ring 12 rotates synchronously with the third gear 122.

[0061] The working method of the automatic drill hotting machine is as follows: the drills are poured into the drill storage trough 11, and the automatic drill feeding component works, wherein the drill sorting ring driving 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 trough 11 will automatically fall into the drill row groove 121 of the drill sorting ring 12 due to their own weight. When the drills in the drill row groove 121 rotate with the drill sorting ring 12, they pass through the drill picking part 14. If the drills fall into the drill row groove 121 correctly, they will not be brushed off by the brush. Otherwise, they will be brushed off by the brush and wait for the next drop. In this way, it can effectively ensure that the drills discharged by the drill sorting ring 12 face in a consistent manner.

[0062] When the drill follows the drill sorting ring 12 to rotate to the lower drill stop bar 31, the suction nozzle will suck the drill and prepare for drilling. At this time, the front and rear drivers of the lower drill stop bar drive the lower drill stop bar 31 to move backward to expose the drill row slot 121. At this time, the upper and lower drivers of the suction nozzle drive the suction nozzle to move downward to send the drill to the adhesive tape below. The suction nozzle releases the suction force to allow the drill to adhere to the adhesive tape and stay on the adhesive tape. The suction nozzle returns to the drill suction position. At this time, the embroidery frame inlaid with the adhesive tape will move a position according to the needs of the pattern design to prepare for placing the next drill.

[0063] When it is necessary to change the color and arrange other colors or specifications of drills, the upper and lower drivers of the suction nozzle will raise the suction nozzle to the top, that is, the avoidance position, leaving movable space for the automatic drill feeding component 100. The automatic drill feeding component 100 will move to the drill storage trough 11 position of the next color or specification under the drive of the color changing mechanism.

[0064] Repeat the above steps according to the design, leaving beautiful patterns on the tape.

[0065] like Fig.11 As shown, in some of the embodiments, a single motor driven drill arrangement structure can also be used, and only one drill sorting ring drive motor 13 is set. The single motor driven drill arrangement structure includes a first rotating member driven to rotate by the drill sorting ring drive motor 13, and a second rotating member that drives the drill sorting ring to rotate. The first rotating member drives the second rotating member to rotate, and when changing colors, the first rotating member and the second rotating member move relative to each other along the X direction to achieve separation and transmission connection.

[0066] Here, the first rotating member is the first gear 194, and the second rotating member is the second gear 18. The second gear is arranged in the same manner as in the embodiment in which each automatic diamond feeding component is provided with a diamond sorting ring driving motor 13 to drive the diamond sorting ring 12. A third belt transmission assembly is arranged between the diamond sorting ring driving motor 13 and the first gear 194. The first gear 194 is mounted on the first gear shaft, and the third belt transmission assembly includes a third driven pulley mounted on the first gear shaft, a third driving pulley mounted on the output shaft of the diamond sorting ring driving motor, and a third transmission belt connecting the third driving pulley and the third driven pulley. Therefore, the first gear 194 is fixed in the X direction, and when changing colors, the multi-color automatic diamond feeding component moves along the X direction, and the second gear of one automatic diamond feeding component is separated from the first gear. After changing colors, the second gear of another automatic diamond feeding component is connected to the first gear in transmission. It can be understood that the first rotating member and the second rotating member can also be replaced by other rotating members.

[0067] like Figure 2 As shown, in order to facilitate the installation of the third belt transmission assembly and the drill sorting ring drive motor, a transmission seat 19 is installed at the rear side of the head fixing seat. The transmission seat 19 is L-shaped, including a vertical section 191 and a horizontal section 192, wherein the vertical section is fixed to the rear side of the 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 head fixing seat, and a through groove 193 that passes through the front and back is provided between the lower end of the vertical section and the middle of the horizontal section. The second gear 18 is arranged 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 transmission belt is also located inside the through groove 193. The drill sorting 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 side section, a rear side section and a middle section, wherein the drill sorting ring drive motor is installed on the side of the rear side section, and the front side section extends along the X direction and is connected to the transmission seat.

[0068] When each color is fed, the drill sorting ring driving motor drives the drill sorting ring of one of the automatic drill feeding components, the drill sorting ring driving motor drives the first rotating member to rotate, the second rotating member drives the drill sorting ring to rotate, and the first rotating member drives the second rotating member to rotate. When changing colors, the first rotating member and the second rotating member move relative to each other along the X direction to achieve separation and transmission connection. In this way, there is no need to set a drill sorting ring driving motor for each automatic drill feeding component, which can reduce the number of motors and significantly reduce costs.

[0069] In the above embodiment, whether it is a multi-motor driven drilling structure or a single motor driven drilling structure, the rotating shaft not only has the function of installing the second gear, but also serves as a part of the lower drill stop bar assembly 300 for installing the fourth gear 33 and the second driven pulley in the second belt transmission assembly 36.

[0070] The above is only a specific embodiment of the invention, but the protection scope 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 drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
