Description

Technical Field

[0001] This utility model generally relates to the field of computer embroidery machine technology, and more particularly to a device for embroidering metal wires. Background Technology

[0002] Metallic wire, also known as spring wire or Indian wire, is a copper-based, spring-shaped material that is electroplated and can reach a diameter of 0.02mm. It is corrosion-resistant, highly reflective, and more eye-catching than ordinary embroidery thread. Due to its spring-like properties, it is flexible and adaptable, making it easier to express the texture and shape of objects. From a distance, the reflective metallic wire resembles beads, with exquisite patterns and a rich metallic luster and texture, effectively enhancing clothing and elevating one's presence.

[0003] Because of the special structure of metal wire, it needs to be cut to a certain length according to the needs of the embroidery pattern during the embroidery process. In related technologies, metal wire embroidery has always been hand embroidery and has never been automated. Utility Model Content

[0004] This application aims to provide an apparatus for embroidering metallic threads, at least for automating the embroidery of metallic threads.

[0005] This utility model provides a device for embroidering metal wire, including: a wire cutting and clamping mechanism.

[0006] The wire cutting and clamping mechanism includes a wire clamping assembly and a wire cutting assembly. The wire cutting assembly includes a moving blade and a fixed blade arranged opposite to each other. The moving blade moves closer to or further away from the fixed blade to cut the metal wire into metal wire segments of a preset length.

[0007] The wire clamping assembly includes a wire clamping component and a wire clamping base. The wire clamping base has a sliding groove, and the wire clamping component is disposed within the sliding groove. The wire clamping component reciprocates along the sliding groove to have a wire clamping position and an embroidery position. The moving knife and the fixed knife are arranged vertically above and below the wire clamping base, and the moving knife and the fixed knife are located on both sides of the sliding groove.

[0008] The wire clamping component includes two clamping arms, each clamping arm including a clamping arm body. A clamping portion for clamping the metal wire segment is formed by a partial protrusion on the surface of the clamping arm body facing the moving knife or the fixed knife.

[0009] As an alternative implementation, the wire cutting and clamping mechanism further includes a wire feeding auxiliary assembly, which comprises a wire feeding drive wheel and a wire feeding driven wheel. The wire feeding drive wheel and the wire feeding driven wheel abut against each other, with the metal wire clamped between them. The wire feeding drive wheel and the wire feeding driven wheel engage in frictional cooperation to transport the metal wire.

[0010] The wire cutting assembly cuts the metal wire into segments of different lengths according to the different rotation angles of the wire feeding drive wheel.

[0011] As an implementation method, one of the wire feeding passive wheel and the wire feeding active wheel is mounted by a spring, and the wire feeding passive wheel and the wire feeding active wheel elastically abut against each other.

[0012] As an implementation method, at least one of the sides of the wire feeding drive wheel and the wire feeding passive wheel that are in contact with each other is provided with a groove that matches the metal wire. The groove is arc-shaped or circular, and the axis corresponding to the groove is on the same straight line as the axis of the wire feeding drive wheel or the wire feeding passive wheel.

[0013] As an alternative, the surface of the groove that contacts the metal wire is a patterned surface.

[0014] As one possible implementation, the wire clamping seat has a moving blade mounting groove and a fixed blade mounting area on its surface facing the moving blade or the fixed blade. The moving blade mounting groove and the fixed blade mounting area are located on both sides of the slide groove and are arranged opposite to each other.

[0015] The moving blade is movably connected to the moving blade mounting slot, and the fixed blade is fixedly connected to the fixed blade mounting area.

[0016] As one possible implementation, the wire-cutting assembly further includes a rotating component, a cam follower, and a follower component.

[0017] The cam follower is connected to the rotating member, and the follower is provided with a guide channel. The cam follower is tumbling within the guide channel. The moving blade is connected to the follower. When the rotating member rotates, the cam follower rolls within the guide channel, causing the moving blade to move along the extension direction of the moving blade mounting groove.

[0018] As one possible implementation, the wire cutting and clamping mechanism further includes a wire guide assembly, which comprises a wire guide tube through which the metal wire passes, and the wire guide tube is located between the moving blade, the fixed blade, the wire feeding drive wheel, and the wire feeding driven wheel.

[0019] The guide tube reciprocates in the direction from the moving blade, the fixed blade to the wire feeding drive wheel, and the wire feeding driven wheel.

[0020] As one possible implementation, the guide wire assembly also includes a tube holder, a meshing drive gear and rack, and a guide structure.

[0021] The guide tube is connected to the tube fixing seat, the tube fixing seat is connected to the rack, and the guide structure is guided and cooperated with the tube fixing seat to make the guide tube move in the direction of the moving knife, the fixed knife to the wire feeding drive wheel and the wire feeding driven wheel.

[0022] As an alternative implementation, a wire feeding mechanism located above the wire cutting and clamping mechanism is also included.

[0023] The wire feeding mechanism includes a support base, a pulley assembly, and a drum. A metal wire is wound on the drum, which is rotatably connected to the support base. The pulley assembly is mounted on the support base and is used to drive the drum to rotate and output the metal wire.

[0024] The above solution uses a combination of moving and stationary blades to cut the metal wire into segments of a preset length L1. The wire clamping mechanism can switch between the clamping position and the embroidery position, allowing the metal segments to be transported from the clamping position to the embroidery position. The metal wires can then be vertically embroidered onto the fabric, resulting in exquisite patterns with a rich metallic sheen and texture. This allows for automated embroidery of metal wire segments. Attached Figure Description

[0050] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] At least see Figures 1-14 As shown, this utility model provides a device 100 for embroidering metal wires, which is applied to a computerized embroidery machine.

[0053] like Figure 1 and Figure 2 As shown, the embroidery device 100 of this application can be connected to the needle bar frame 200 of the machine head. The embroidery device 100 cooperates with the machine needle to automate the embroidery of metal threads. 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 transport the metal thread to the wire cutting and clamping mechanism 10, and the telescopic mechanism 30 is used to move the wire cutting and clamping mechanism 10 to have a working position and a clearance position.

[0054] like Figure 13 As shown, the wire feeding mechanism 20 includes a support base 21, a pulley assembly 22, and a drum 25. Metal wire is wound on the drum 25, which 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 drum 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 drive shafts 223. The first synchronous pulley 221 and the two second synchronous pulleys 222 are arranged in an inverted triangle. The axes of the first synchronous pulley 221, the second synchronous pulleys 222, and the drum 25 are parallel, with the drum 25 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 drive shafts 223 correspond one-to-one with the second synchronous pulleys 222, passing through the second synchronous pulleys 222 and being coaxial. The gear portion 2231 on the drive shaft 223 is correspondingly disposed with the drum hub 251 of the drum 25, and the two mesh with each other.

[0056] When the first synchronous pulley 221 rotates, it drives the two second synchronous pulleys 222 to rotate, thereby causing the two drive shafts 223 to rotate. Since the gear part 2231 of the drive shaft 223 meshes with the drum hub 251 of the drum 25, the drum 25 rotates and outputs metal wire.

[0057] In addition, such as Figure 13 As shown, a swing arm 23 and an elastic plate 24 are also installed on the support base 21, with the elastic plate 24 positioned vertically above the swing arm 23. The through hole of the swing arm 23 and the elastic plate 24 work together to guide the metal wire on the drum 25 downwards. The swing arm 23 has a through hole for the metal wire to pass through, and the elastic plate 24 ensures that the metal wire output from the drum 25 passes through the through hole of the swing arm 23 as smoothly as possible in the vertical direction.

[0058] In practical applications, during the wire feeding process, the swing arm 27 swings at an angle, and when the wire feeding stops, the swing arm 27 returns to its initial position. By placing sensors around the swing arm 27 to detect whether the swing arm 27 is swinging, the operator can be alerted whether the wire is being fed out.

[0059] like Figure 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 inclined 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 mounted on the needle bar frame 200 of the computerized embroidery machine, and the telescopic member 31 and the aforementioned 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, thus having a working position and a clearance position.

[0060] The wire cutting and clamping mechanism 10 includes a wire clamping assembly 11 and a wire cutting assembly 12. The wire cutting assembly 12 includes a movable blade 125 and a fixed blade 126 arranged opposite to each other. The movable blade 125 moves closer to or further away from the fixed blade 126 to cut the metal wire into metal wire segments of a 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 sliding groove 1181. The wire clamping member 117 is disposed in the sliding groove 1181 and reciprocates along the sliding groove 1181 to have a wire clamping position and an embroidery position. A movable knife 125 and a fixed knife 126 are arranged vertically above and below the wire clamping seat 118, and the movable knife 125 and the fixed knife 126 are located on both sides of the sliding groove 1181. The wire clamping member 117 includes two clamping arms 1171. Each clamping arm 1171 includes a clamping arm body. A clamping portion 11711 for clamping a metal wire segment is protruded from 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 spool 25 first passes through the wire-cutting assembly 12, which cuts the metal wire into segments of a preset length. The wire clamping member 117 holds the metal wire segment at the wire-holding position via the clamping portions 11711 of its two clamping arms 1171. The clamping member 117 then moves from the wire-holding position to the embroidery position. At the embroidery position, the clamping portions 11711 of the two clamping arms 1171 move away from each other, releasing the metal wire segment so that the needle can embroider it. In this way, the wire-cutting and clamping mechanism 10 can cut the metal wire into segments, and these segments can be placed under the needle so that the needle can perform the embroidery action, thus realizing automatic metal wire embroidery. This process improves the efficiency of metal wire embroidery and reduces production costs.

[0063] In detail, such as Figures 3-10 As shown, the wire cutting and clamping mechanism 10 includes 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 Figures 6-10 As shown, the wire clamping assembly 11 includes a third synchronous pulley 111, a fourth synchronous pulley 112, a second synchronous belt 113 for winding the third synchronous pulley 111 and the fourth synchronous pulley 112, a hinge shaft 114, a rocker arm 115, a pusher plate 116, a wire clamping component 117, and a wire clamping seat 118.

[0065] The hinge shaft 114 passes through the third synchronous pulley 111. One end of the swing arm 115 is sleeved on the hinge shaft 114, and the other end is hinged to the push plate 116. The push plate 116 is provided with a wire clamping component 117. The wire clamping seat 118 is provided with a sliding groove 1181, and the wire clamping component 117 is disposed in the sliding groove 1181. The third synchronous pulley 111 drives the fourth synchronous pulley 112 to rotate, thereby causing the hinge shaft 114 to rotate and the swing arm 115 to swing. Based on the swing of the swing arm 115, the wire clamping component 117 reciprocates along the sliding groove 1181, thus having a wire clamping position and an embroidery position.

[0066] Among them, such as Figure 9 As shown, the wire clamping member 117 is plate-shaped, including a middle plate 1172, side plates 1173 on both sides of the middle plate 1172, and a clamping arm 1171 between the side plates 1173 and the middle plate 1172. The clamping arm 1171 includes a clamping arm body, which consists of a clamping part 11711 and a non-clamping part 11712. A clamping part 11711 is protruding in a local area on the surface of the clamping arm body facing the moving knife 125 or the fixed knife 126 to form a clamping part for clamping the metal wire segment. The thickness of the clamping part 11711 and the middle plate 1172 are equal, and the thicknesses of the non-clamping part 11712, the side plates 1173, and the middle plate 1172 are equal. The thickness of the clamping part 11711 is greater than the thickness of the non-clamping part 11712.

[0067] An arc-shaped notch 117111 is provided on the clamping part 11711. After the two clamping parts 11711 are closed, the two arc-shaped notches 117111 form a complete wire clamping hole C. An inclined extrusion groove 117121 is provided on the non-clamping part 11712, and the opening of the extrusion groove 117121 faces away from the intermediate plate 1172.

[0068] like Figure 10 As shown, a fixing post 1161 is provided at the end of the push plate 116. The fixing post 11611 is located in the extrusion groove 117121. When the wire clamping member 117 moves, the fixing post 11611 and the extrusion groove 117121 control the opening of the wire clamping hole C, thereby enabling the wire clamping member 117 to clamp the wire at the wire clamping position; and control the closing of the wire clamping hole C, thereby enabling the wire clamping member 117 to release the wire at the embroidery position.

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

[0070] like Figure 3As shown, the wire-cutting assembly 12 includes a main gear 121 and a driven gear 122 that mesh with each other, a cam follower 123, a follower element 124, a moving blade 125, and a fixed blade 126. Among them, the rotating element is the driven gear 122, the moving blade 125 is movably connected to the moving blade mounting groove 1182, and the fixed blade 126 is fixedly connected to the fixed blade mounting area 1183.

[0071] A cam follower 123 is connected to a driven gear 122. A guide channel 1241 is provided on the follower 124. The cam follower 123 is rotatably disposed within the guide channel 1241. A moving blade 125 is connected to the follower 124. When the driven gear 122 rotates, the cam follower 123 rolls within the guide channel 1241, causing the moving blade 125 to move along the extending direction of the moving blade mounting groove 1182.

[0072] The main gear 121 drives the driven gear 122 to rotate, thereby causing the cam follower 123 to rotate around the axis of the driven gear 122 by an angle. The follower 124 drives the moving blade 125 to move. In this way, the moving blade 125 moves along the extension direction of the moving blade mounting groove 1182. The moving blade 125 cooperates with the fixed blade 126 to cut the metal wire into a metal wire segment of a preset length L1.

[0073] As an alternative implementation, the wire cutting and clamping mechanism 10 also includes a wire feeding auxiliary component 13, which is used to assist in conveying the metal wire so that the metal wire is stably conveyed to the wire clamping component 11.

[0074] In a specific embodiment, such as Figure 3 and Figure 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 belt pulley structure, including a wire feeding drive pulley 1312, a fifth synchronous belt pulley 1311, and a third synchronous belt 1313 wound around the fifth synchronous belt pulley 1311 and the wire feeding drive pulley 1312. The fifth synchronous belt pulley 1311 and the wire feeding drive pulley 1312 are rotatably connected to the first support frame 15. Wherein, as... Figure 11 As shown, the wire feeding drive wheel 1312 includes a friction wheel portion 13121 and a pulley portion 13122 arranged coaxially.

[0075] The second friction wheel structure 132 includes a wire feeding driven wheel 1321, a rotating shaft 1322, screws 1323, springs 1324, and a support frame 1325. The wire feeding driven wheel 1321 is sleeved on the rotating shaft 1322. Two screws 1323 pass through both ends of the rotating shaft 1322, with one end of each screw connected to the support frame 1325 and the other end connected to a nut. Two springs 1324 are respectively sleeved on the two screws 1323, and the rotating shaft 1322 presses the springs 1324 onto the screws 1323.

[0076] like Figure 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 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 driven wheel 1321. The second groove 13211 may be circular or arc-shaped, and its corresponding axis is on the same straight line as the axis of the wire feeding driven wheel 1321. At least part of the metal wire is located in the second groove 13211.

[0078] like Figure 11 As shown, the metal wire is clamped between the wire feeding passive wheel 1321 and the friction wheel 13121, that is, the metal wire is clamped in the combination structure of the first groove 131211 and the second groove 13211. This combination structure has a limiting effect on the metal wire and prevents the metal wire from moving.

[0079] When the wire feeding drive wheel 1312 rotates, the wire feeding driven wheel 1321 engages with the friction wheel 13121 to feed the metal wire. Furthermore, as the wire diameter changes, the interaction force between the wire feeding driven wheel 1321 and the friction wheel 13121 also changes accordingly, preventing the wire from getting stuck at the changing diameter position and contributing to stable wire feeding.

[0080] Furthermore, in some embodiments, the inner surface of the first groove 131211 can be a patterned surface, and the inner surface of the second groove 13211 can be a smooth surface; or, the inner surface of the first groove 131211 can be a smooth surface, and the inner surface of the second groove 13211 can be a patterned surface; or, the inner surface of the first groove 131211 can be a patterned surface, and the inner surface of the second groove 13211 can be a patterned surface. The patterned surface can be formed by protrusions, grooves, scratches, etc., which is designed to increase the friction on the metal wire, thereby facilitating the conveying of the metal wire.

[0081] Furthermore, it should be noted that the output rate of the metal wire can be adjusted by varying the rotation angle of the wire feeding drive wheel 1312, i.e., the speed of its rotation. When the output rate increases, the preset length L1 can be adjusted to L2, where L2 is less than L1; conversely, when the output rate decreases, the preset length L1 can be adjusted to L3, where L3 is greater than L1. This allows for adjustment of the preset length of the metal wire segment based on the rotation speed of the wire feeding drive wheel 1312, enabling the selection of an appropriate length according to the embroidery requirements.

[0082] As an alternative implementation, the wire cutting and clamping mechanism 10 further includes a wire guide assembly 14. The wire guide assembly 14 is used to guide the metal wire into the wire clamping hole C on the aforementioned wire clamping member 117.

[0083] like Figure 3 and Figure 12 As shown, the guide wire assembly 14 includes a drive gear 141, a rack 142, a tube holder 143, and a guide wire tube 144. The tube holder 143 is movably connected to the first support frame 15 via a guide structure. The guide structure includes a slidingly fitted track and a slider, one of which is connected to the first support frame 15, and the other is connected to the tube holder 143.

[0084] A wire guide tube 144 passes through the tube holder 143 and is used to thread a metal wire. The wire guide tube 144 is located below the wire feeding drive wheel 1312 and the wire feeding driven wheel 1321, and above the moving blade 125 and the fixed blade 126. A rack 142 is connected to the tube holder 143, and a drive gear 141 meshes with the rack 142. The length directions of the rack 142 and the wire guide tube 144 are parallel to the wire feeding direction.

[0085] The drive gear 141 rotates, which drives the rack 142 to reciprocate, thereby causing the tube fixing seat 143 to reciprocate. In this way, the guide tube 144 can reciprocate between the moving knife 125, the fixed knife 126, the wire feeding drive wheel 1312, and the wire feeding driven wheel 1321.

[0086] By ensuring that the axis of the wire guide tube 144 is on the same straight line as the axis of the wire clamping hole C, the wire can be accurately positioned to enter the wire clamping hole C, thereby allowing the wire clamping member 117 to hold the wire at the wire clamping position.
