[0050] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] At least see Figure 1-Figure 14 As shown, the present invention provides an example of a device 100 for embroidering metal wires, which is applied to a computer embroidery machine.

[0053] like Figure 1 and Figure 2 As shown, the device 100 for embroidering metal wires of the present application can be connected to the needle bar frame 200 of the machine head. The device 100 for embroidering metal wires cooperates with the machine needle to automatically embroider metal wires. The device includes a wire cutting and clamping mechanism 10, a wire feeding mechanism 20, and a telescopic mechanism 30. The wire feeding mechanism 20 is used to convey metal wires to the wire cutting and clamping mechanism 10, and the telescopic mechanism 30 is used to make the wire cutting and clamping mechanism 10 move to have a working position and an avoidance position.

[0054] like Fig.13 As shown, the wire feeding mechanism 20 includes a support base 21, a pulley assembly 22 and a reel 25. The reel 25 is wound with a metal wire, and the reel 25 is rotatably connected to the support base 21. The pulley assembly 22 is mounted on the support base 21, and is used to drive the reel 25 to rotate and output the metal wire.

[0055] The pulley assembly 22 includes a first synchronous pulley 221, a first synchronous belt 224, two second synchronous pulleys 222 and two transmission shafts 223. The first synchronous pulley 221 and the two second synchronous pulleys 222 are arranged in an inverted triangle, and the axes of the first synchronous pulley 221, the second synchronous pulley 222 and the reel 25 are arranged in parallel, and the reel 25 is located between the two second synchronous pulleys 222. The first synchronous belt 224 is wound around the first synchronous pulley 221 and the two second synchronous pulleys 222. The transmission shaft 223 corresponds to the second synchronous pulley 222 one by one, and the transmission shaft 223 passes through the second synchronous pulley 222 and is coaxially arranged. The gear portion 2231 on the transmission shaft 223 is arranged correspondingly to the reel hub 251 of the reel 25, and the two are meshed and matched.

[0056] When the first synchronous pulley 221 rotates, the two second synchronous pulleys 222 are driven to rotate, thereby causing the two transmission shafts 223 to rotate. Since the gear portion 2231 of the transmission shaft 223 is engaged with the drum hub 251 of the drum 25, the drum 25 rotates to output the metal wire.

[0057] In addition, if Fig.13 As shown, a swing arm 23 and an elastic plate 24 are also installed on the support seat 21, and the elastic plate 24 is arranged above and below the swing arm 23. The through hole of the swing arm 23 and the elastic plate 24 cooperate with each other to guide the metal wire on the reel 25 to be output downward. The swing arm 23 is provided with a through hole for passing the metal wire, and the elastic plate 24 allows the metal wire output from the reel 25 to pass through the through hole of the swing arm 23 as smoothly as possible in the vertical direction.

[0058] In actual application, during the process of conveying the wire, the swing arm 27 swings at an angle, and when the wire feeding stops, the swing arm 27 returns to its initial position. A sensor is arranged around the swing arm 27 to detect whether the swing arm 27 swings, so as to remind the operator whether the wire is output.

[0059] like Fig.14 As shown, the telescopic mechanism 30 includes a second support frame 32 and a telescopic member 31. The telescopic member 31 can be an electric telescopic rod, a pneumatic telescopic rod, a hydraulic telescopic rod, etc. The telescopic rod 31 is tilted relative to the vertical direction, such as Figure 1 or Figure 2 As shown, it moves in the direction of the arrow. The second support frame 32 is installed on the needle bar frame 200 of the computer embroidery machine, and the telescopic member 31 and the above-mentioned wire feeding mechanism 20 are connected to the second support frame 32. The movable end of the telescopic member 31 allows the wire cutting and clamping mechanism 10 to move in the direction of the arrow and have a working position and an avoidance position.

[0060] The wire cutting and clamping mechanism 10 comprises a wire clamping assembly 11 and a wire cutting assembly 12. The wire cutting assembly 12 comprises a movable knife 125 and a fixed knife 126 which are arranged opposite to each other. The movable knife 125 approaches or moves away from the fixed knife 126 to cut the metal wire into metal wire segments of preset length.

[0061] The wire clamping assembly 11 includes a wire clamping member 117 and a wire clamping seat 118. The wire clamping seat 118 is provided with a slide groove 1181. The wire clamping member 117 is arranged in the slide groove 1181, and the wire clamping member 117 reciprocates along the slide groove 1181 to have a wire clamping position and an embroidery position. The movable knife 125 and the fixed knife 126 are arranged up and down with the wire clamping seat 118, and the movable knife 125 and the fixed knife 126 are located on both sides of the slide groove 1181. The wire clamping member 117 includes two clamping arms 1171, and the clamping arm 1171 includes a clamping arm body. A clamping portion 11711 for clamping a metal wire segment is protruded on a local area on the surface of the clamping arm body facing the movable knife 125 or the fixed knife 126.

[0062] The metal wire output from the reel 25 first passes through the wire cutting assembly 12, and the wire cutting assembly 12 cuts the metal wire into metal wire segments of a preset length. The wire clamping member 117 clamps the metal wire segment through the clamping portion 11711 of its two clamping arms 1171 at the wire clamping position, and the wire clamping member 117 moves from the wire clamping position to the embroidery position. In the embroidery position, the clamping portions 11711 of the two clamping arms 1171 move away from each other to release the metal wire segment, so that the machine needle can embroider the metal wire segment. In this way, the wire cutting and clamping mechanism 10 can complete the shearing of the metal wire into metal wire segments, and the metal wire segments can be placed under the machine needle, so that the machine needle can complete the embroidery action with the metal wire segment, thereby realizing the process of automatic metal wire embroidery. This process improves the efficiency of metal wire embroidery and reduces production costs.

[0063] In detail, Figure 3-Figure 10 As shown, the wire cutting and clamping mechanism 10 comprises a wire clamping assembly 11, a wire cutting assembly 12 and a first support frame 15. The wire clamping assembly 11 and the wire cutting assembly 12 are connected to the first support frame 15.

[0064] like Figure 6-Figure 10 As shown, the wire clamping assembly 11 includes a third synchronous pulley 111, a fourth synchronous pulley 112, a second synchronous belt 113 wrapped around the third synchronous pulley 111 and the fourth synchronous pulley 112, a hinge shaft 114, a rocker arm 115, a pushing plate 116, a wire clamping member 117 and a wire clamping seat 118.

[0065] The articulated shaft 114 passes through the third synchronous pulley 111, one end of the swing rod 115 is sleeved on the articulated shaft 114, and the other end is hingedly connected to the push plate 116, and the push plate 116 is provided with a wire clamping member 117. The wire clamping seat 118 is provided with a slide groove 1181, and the wire clamping member 117 is arranged in the slide groove 1181. The third synchronous pulley 111 drives the fourth synchronous pulley 112 to rotate, so that the articulated shaft 114 rotates and the swing rod 115 swings. Based on the swing of the swing rod 115, the wire clamping member 117 reciprocates along the slide groove 1181 and has a wire clamping position and an embroidery position.

[0066] Among them, Fig. 9 As shown, the wire clamping member 117 is in the shape of a plate, including an intermediate plate 1172, side plates 1173 are arranged on both sides of the intermediate plate 1172, and a clamping arm 1171 is arranged between the side plates 1173 and the intermediate plate 1172. The clamping arm 1171 includes a clamping arm body, and the clamping arm body is composed of a clamping portion 11711 and a non-clamping portion 11712. A clamping portion 11711 for clamping a metal wire segment is convexly provided in a local area on the surface of the clamping arm body facing the movable knife 125 or the fixed knife 126, and the thickness of the clamping portion 11711 and the intermediate plate 1172 is equal, and the thickness of the non-clamping portion 11712, the side plates 1173, and the intermediate plate 1172 is equal, and the thickness of the clamping portion 11711 is greater than the thickness of the non-clamping portion 11712.

[0067] The clamping portion 11711 is provided with an arc-shaped notch 117111 , and when the two clamping portions 11711 are closed, the two arc-shaped notches 117111 form a complete wire clamping hole C. The non-clamping portion 11712 is provided with an inclined extrusion groove 117121 , and the notch of the extrusion groove 117121 faces away from the middle plate 1172 .

[0068] like Fig.10 As shown, a fixed column 1161 is provided at the end of the pushing plate 116, and the fixed column 11611 is located in the extrusion groove 117121. When the wire clamping member 117 moves, the opening of the wire clamping hole C is controlled by the fixed column 11611 and the extrusion groove 117121, so that the wire clamping member 117 can clamp the wire at the wire clamping position; and the closing of the wire clamping hole C can be controlled, so that the wire clamping member 117 can release the wire at the embroidery position.

[0069] Among them, Figure 7 As shown, a movable knife mounting groove 1182 and a fixed knife mounting area 1183 are provided on the surface of the wire clamping seat 118 facing the movable knife 125 or the fixed knife 126. The movable knife mounting groove 1182 and the fixed knife mounting area 1183 are respectively located on both sides of the slide groove 1181 and are arranged opposite to each other.

[0070] like Figure 3 As shown, the wire cutting assembly 12 includes a main gear 121 and a slave gear 122 meshing with each other, a cam follower 123, a follower 124, a moving knife 125 and a fixed knife 126. Among them, the rotating member is the slave gear 122, the moving knife 125 is movably connected to the moving knife installation groove 1182, and the fixed knife 126 is fixedly connected to the fixed knife installation area 1183.

[0071] The cam follower 123 is connected to the slave gear 122, and a guide channel 1241 is provided on the follower 124. The cam follower 123 is rolled in the guide channel 1241, and the movable knife 125 is connected to the follower 124. The slave gear 122 rotates, and the cam follower 123 rolls in the guide channel 1241, so that the movable knife 125 moves along the extension direction of the movable knife installation groove 1182.

[0072] The main gear 121 drives the slave gear 122 to rotate, so that the slave gear 122 causes the cam follower 123 to rotate an angle around the axis of the slave gear 122, and the follower 124 drives the movable knife 125 to move, so that the movable knife 125 moves along the extension direction of the movable knife mounting groove 1182, and the movable knife 125 cooperates with the fixed knife 126 to complete the shearing of the metal wire, so as to cut the metal wire into a metal wire segment of a preset length L1.

[0073] As an implementable manner, the wire cutting and clamping mechanism 10 further includes a wire feeding auxiliary component 13 , and the wire feeding auxiliary component 13 is used to assist in transferring the metal wire so that the metal wire is stably delivered to the wire clamping component 11 .

[0074] In a specific embodiment, Figure 3 and Fig.11 As shown, the wire feeding auxiliary assembly 13 includes a first friction wheel structure 131 and a second friction wheel structure 132. The first friction wheel structure 131 is a synchronous pulley structure, including a wire feeding driving wheel 1312, a fifth synchronous pulley 1311, and a third synchronous belt 1313 wound around the fifth synchronous pulley 1311 and the wire feeding driving wheel 1312. The fifth synchronous pulley 1311 and the wire feeding driving wheel 1312 are rotatably connected to the first support frame 15. Fig.11 As shown, the wire feeding driving wheel 1312 includes a friction wheel portion 13121 and a pulley portion 13122 which are coaxially arranged.

[0075] The second friction wheel structure 132 includes a wire feeding passive wheel 1321, a rotating shaft 1322, a screw 1323, a spring 1324 and a support frame 1325. The wire feeding passive wheel 1321 is sleeved on the rotating shaft 1322, and two screws 1323 pass through the two ends of the rotating shaft 1322 respectively. One end of the screw 1323 is connected to the support frame 1325, and the other end is connected to a nut. Among them, the two springs 1324 are respectively sleeved on the two screws 1323, and the springs 1324 are pressed onto the screws 1323 through the rotating shaft 1322.

[0076] like Fig.11 As shown, a first groove 131211 may be provided on the side of the friction wheel portion 13121. The first groove 131211 may be circular or arc-shaped, and its corresponding axis is located on the same straight line as the axis of the friction wheel portion 13121. At least part of the metal wire is located in the first groove 131211.

[0077] A second groove 13211 may be provided on the side of the wire feeding passive wheel 1321 . The second groove 13211 may be circular or arc-shaped, and its corresponding axis is located on the same straight line as the axis of the wire feeding passive wheel 1321 . At least part of the metal wire is located in the second groove 13211 .

[0078] like Fig.11 As shown, the wire clamp is arranged between the wire feeding passive wheel 1321 and the friction wheel part 13121, that is, the wire clamp is arranged in the combination structure of the first groove 131211 and the second groove 13211, and the combination structure has a limiting effect on the wire to prevent the wire from moving.

[0079] When the wire feeding active wheel 1312 rotates, the wire feeding passive wheel 1321 and the friction wheel part 13121 are frictionally matched to realize the feeding of the metal wire. In addition, at the position where the diameter of the metal wire changes, the interaction force between the wire feeding passive wheel 1321 and the friction wheel part 13121 also changes adaptively, avoiding the position where the diameter of the metal wire changes and being stuck in the wire feeding passive wheel 1321 and the friction wheel part 13121, which helps to stably feed the metal wire.

[0080] Further, in some embodiments, the inner surface of the first groove 131211 may be a patterned surface, and the inner surface of the second groove 13211 may be a smooth surface; or, the inner surface of the first groove 131211 may be a smooth surface, and the inner surface of the second groove 13211 may be a patterned surface; or, the inner surface of the first groove 131211 may be a patterned surface, and the inner surface of the second groove 13211 may be a patterned surface. The patterned surface may be formed in the form of protrusions, grooves, scratches, etc., so as to increase the friction force on the metal wire, thereby facilitating the conveyance of the metal wire.

[0081] In addition, it should be noted that the output rate of the metal wire can be adjusted by the different rotation angles of the wire feeding driving wheel 1312, that is, the rotation angle speed of the wire feeding driving wheel 1312. When the output rate of the metal wire is accelerated, the preset length L1 can be adjusted to L2, and L2 is less than L1; when the output rate of the metal wire is slowed down, the preset length L1 can be adjusted to L3, and L3 is greater than L1. In this way, the preset length of the metal wire segment can be adjusted according to the rotation speed of the wire feeding driving wheel 1312, so as to select a suitable length according to the embroidery needs.

[0082] As an implementable manner, the wire cutting and clamping mechanism 10 further comprises a wire guiding assembly 14. The wire guiding assembly 14 is used to guide the metal wire into the metal wire clamping hole C on the above-mentioned wire clamping member 117.

[0083] like Figure 3 and Fig.12 As shown, the guide wire assembly 14 includes a driving gear 141, a rack 142, a tube fixing seat 143 and a guide wire tube 144. The tube fixing seat 143 is movably connected to the first support frame 15 through a guide structure, and the guide structure includes a sliding track and a slider, one of which is connected to the first support frame 15, and the other is connected to the tube fixing seat 143.

[0084] The wire guide tube 144 is arranged through the tube fixing seat 143, and is used to pass the metal wire. The wire guide tube 144 is located below the wire feeding active wheel 1312 and the wire feeding passive wheel 1321, and is located above the movable knife 125 and the fixed knife 126. The rack 142 is connected to the tube fixing seat 143, and the driving gear 141 is meshed with the rack 142. Among them, the length direction of the rack 142 and the length direction of the wire guide tube 144 are parallel to the metal wire feeding direction.

[0085] The driving gear 141 rotates, driving the rack 142 to reciprocate, thereby causing the tube fixing seat 143 to reciprocate, so that the wire guide tube 144 can reciprocate between the movable knife 125, the fixed knife 126 and the wire feeding active wheel 1312, the wire feeding passive wheel 1321.

[0086] By locating the axis of the wire guide tube 144 and the axis of the wire clamping hole C on the same straight line, the metal wire can be accurately ensured to enter the position of the wire clamping hole C, so that the wire clamping member 117 clamps the metal wire at the wire clamping position.
