[0032] 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.
[0033] 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.
[0034] The ribbon embroidery device includes a needle bar, a presser foot sleeve 11 located around the needle bar, a material holder tube 21 located around the presser foot sleeve 11, a material holder 40, and a feeding nozzle 30. The needle bar, presser foot sleeve 11, and material holder tube 21 can be coaxially arranged, with their axes coinciding. The presser foot sleeve 11 and the material holder tube 21 can rotate independently of each other, and the presser foot sleeve 11 can reciprocate along its axial extension direction.
[0035] A material wheel is installed on the material rack 40, which is used to wind ribbons or ropes. The material rack 40 is fixedly connected to the material rack tube 21, which can drive the material rack 40 to rotate. The ribbons or ropes output from the material wheel pass through the feed nozzle 30, and the presser foot sleeve 11 can drive the feed nozzle 30 to rotate and move up and down. The nozzle body 33 of the feed nozzle 30 acts as a presser foot and cooperates with the needle on the needle bar to complete the embroidery of the ribbons or ropes.
[0036] In practical applications, due to the size limitations of the feed wheel, the storage capacity of the ribbon or rope wound on it is limited. After the ribbon or rope on the feed wheel is used up, a new feed wheel needs to be replaced, and then the rope or ribbon is passed through the feed nozzle 30. This consumes a significant amount of time, extending the downtime of the ribbon embroidery device and reducing its embroidery efficiency.
[0037] Based on this, this application proposes a ribbon embroidery device in which the material rack 40 and the feed nozzle 30 can be disassembled as a whole when replacing a new material wheel. The rope or ribbon of the material wheel on the material rack 40 to be replaced is passed through the feed nozzle 30 in advance, thereby avoiding the operation of passing the rope or ribbon through the feed nozzle 30 after replacing the new material wheel. This can shorten the time for replacing the new material wheel, reduce the downtime of the ribbon embroidery device, and improve the embroidery efficiency of the ribbon embroidery device.
[0038] The following is at least in conjunction with the accompanying drawings. Figures 1-5 The following describes the ribbon embroidery device:
[0039] A first mating part 42 is provided on the material rack 40, and a second mating part 31 is provided on the feeding nozzle 30. The second mating part 31 and the first mating part 42 are mated together so that the material rack 40 and the feeding nozzle 30 can be detachably mated.
[0040] The feed nozzle 30 and the material rack 40 connected together can be installed as a whole on the combined structure of the presser foot sleeve 11 and the material rack tube 21, or can be completely disassembled from the combined structure.
[0041] In this design, one of the first mating parts 42 and the other of the second mating parts 31 is a first protrusion, and the other is a first groove that matches the first protrusion. The first mating parts 42 and the second mating parts 31 are interlocked. This arrangement makes the assembly process between the material rack 40 and the feed nozzle 30 simple and convenient, without the need for complicated tools or operations.
[0042] like Figure 1 As shown, in the ribbon embroidery device, the material holder 40 and the feed nozzle 30 are arranged vertically when performing ribbon or rope embroidery. The presser foot sleeve 11 moves along its axial direction, driving the feed nozzle 30 to move. The feed nozzle 30 includes a first switching position and a second switching position. Figure 2 and Figure 3 As shown, a first groove is provided on the surface of the material rack 40 facing the feeding nozzle 30, and the opening of the first groove is set downward. A first protrusion is provided on the surface of the feeding nozzle 30 facing the material rack 40, and the protrusion direction of the first protrusion extends in the vertical direction.
[0043] In the first switching position, the first protrusion inserts into the first groove from bottom to top, thus connecting the feed nozzle 30 and the material rack 40 to form a whole. This facilitates the simultaneous disassembly of the material rack 40 and the feed nozzle 30 from the combined structure of the presser foot sleeve 11 and the material rack tube 21. Correspondingly, the material rack 40 and the feed nozzle 30 are simultaneously installed on the combined structure of the presser foot sleeve 11 and the material rack tube 21. In the second switching position, the first protrusion moves from top to bottom, disengaging from the first groove. This separates the feed nozzle 30 from the material rack 40. In the current position, the presser foot sleeve 11 drives the feed nozzle 30 to rotate, or the presser foot sleeve 11 drives the feed nozzle 30 to move up and down; the material rack tube 21 drives the material rack 40 to rotate. The movement of the material rack 40 and the movement of the feed nozzle 30 are independent and do not affect each other.
[0044] The ribbon embroidery device includes at least two material racks 40 and at least two feed nozzles 30. Each material rack 40 corresponds to one feed nozzle 30. For example, the ribbon embroidery device may have three material racks 40 and three feed nozzles 30: a first material rack 40a corresponds to a first feed nozzle 30a, a second material rack 40b corresponds to a second feed nozzle 30b, and a third material rack 40c corresponds to a third feed nozzle 30c. The first material rack 40a is mounted on the material rack tube 21, and the first feed nozzle 30a is mounted on the presser foot sleeve 11. The second material rack 40b is connected to the second feed nozzle 30b, and the rope or ribbon fed from the second material rack 40b passes through the second feed nozzle 30b as a backup for replacement; the third material rack 40c is connected to the third feed nozzle 30c, and the rope or ribbon fed from the third material rack 40c passes through the third feed nozzle 30c as a backup for replacement.
[0045] After the ribbons or ropes on the first material rack 40a are used up, the first material rack 40a is connected to the first feed nozzle 30a and detached from the combined structure of the presser foot sleeve 11 and the material rack tube 21. Then, the second material rack 40b and the second feed nozzle 30b, which are connected together, are installed on the combined structure of the presser foot sleeve 11 and the material rack tube 21. After the ribbons or ropes on the second material rack 40b are used up, the second material rack 40b and the second feed nozzle 30b are connected together and detached from the combined structure of the presser foot sleeve 11 and the material rack tube 21. Next, the third material rack 40c and the third feed nozzle 30c, which are connected together, are installed on the combined structure of the presser foot sleeve 11 and the material rack tube 21. This setup shortens the time for changing new material wheels, reduces the downtime of the ribbon embroidery device, and improves the embroidery efficiency of the ribbon embroidery device.
[0046] It should be noted that the first mating part 42 and the second mating part 31 can be, but are not limited to, an insert mating or a snap-fit mating.
[0047] Furthermore, to improve the firmness of the connection between the material rack 40 and the feed nozzle 30, and to avoid poor stability in the connection between the material rack 40 and the feed nozzle 30, such as... Figure 3 As shown, a first magnetic attractor 43 is provided in the first groove, and a blind hole is opened at the bottom of the first groove, into which the first magnetic attractor 43, such as a magnet, is installed. The first protrusion can be made of ordinary carbon steel. The first protrusion serves as a second magnetic attractor, inserted into the first groove, and attracted and engaged with the first magnetic attractor 43 to lock the first protrusion in the first groove, preventing the first protrusion from accidentally detaching from the first groove.
[0048] The material rack tube 21 is provided with a second connecting part 221, and the pressure foot sleeve 11 is provided with a first connecting part 121. The material rack 40 is also provided with a second connecting mating part 41, and the feed nozzle 30 is also provided with a first connecting mating part 32. The first connecting part 121 and the first connecting mating part 32 cooperate to make the feed nozzle 30 and the pressure foot sleeve 11 detachably connected; the second connecting part 221 and the second connecting mating part 41 cooperate to make the material rack 40 and the material rack tube 21 detachably connected. The cooperation between the first connecting part 121 and the first connecting mating part 32 and the cooperation between the second connecting part 221 and the second connecting mating part 41 occur simultaneously.
[0049] like Figure 2 As shown, a second support frame 22 is connected to the material rack tube 21, and a second connecting portion 221 is formed on the second support frame 22. The second connecting portion 221 includes, but is not limited to, a second protrusion provided on the second support frame 22, the length of which extends in the front-rear direction. The second connecting mating portion 41 includes, but is not limited to, a second groove provided on the material rack 40, the second groove being adapted to the second protrusion.
[0050] like Figure 2 As shown, a first support frame 12 is connected to the pressure foot sleeve 11. A first connecting portion 121 is formed on the first support frame 12. The first connecting portion 121 includes, but is not limited to, a third groove provided on the first support frame 12. A first connecting mating portion 32 includes, but is not limited to, a third protrusion provided on the feed nozzle 30. The length of the third protrusion extends in the front-rear direction, and the third protrusion is adapted to the third groove. The extension direction of the third protrusion is parallel to the extension direction of the second protrusion.
[0051] The second groove engages with the second protrusion, and the third groove engages with the third protrusion. The insertion direction of the second protrusion is parallel to the insertion direction of the third protrusion. This allows the material rack 40 and the feed nozzle 30 to be simultaneously removed from the combined structure of the presser foot sleeve 11 and the material rack tube 21, or the material rack 40 and the feed nozzle 30 to be simultaneously installed on the combined structure of the presser foot sleeve 11 and the material rack tube 21.
[0052] Optionally, the embroidery device also includes a first pin 51 and a first return spring 61.
[0053] At least refer to Figure 2 and Figure 4 As shown, the first support frame 12 is also provided with a first through hole 122 extending in the vertical direction, the first through hole 122 penetrating the third groove, and the extension direction of the first through hole 122 being perpendicular to the depth direction of the third groove. The first pin 51 is provided with a first notch 511, the first notch 511 being adapted to the third protrusion, so that the third protrusion can be located within the first notch 511.
[0054] A first pin 51, fitted with a first return spring 61, is inserted into a first through hole 122 from top to bottom. A third protrusion is inserted into a third groove in a front-to-back direction. The third protrusion is located within a first notch 511. At this moment, the first return spring 61 is in a compressed state. A first fastener 52, fitted with a first anti-rotation washer 53, is threaded from bottom to top to the end of a second pin 54. The ear stop portion of the first anti-rotation washer 53 engages with the first support frame 12 to prevent rotation. In this way, the third protrusion is locked at the first notch 511, improving the connection stability between the third protrusion and the third groove, and avoiding the risk of the feed nozzle 30 accidentally falling off the pressure foot sleeve 11 when the pressure foot sleeve 11 rotates.
[0055] When the feed nozzle 30 is disassembled from the pressure foot sleeve 11, the first fastener 52 and the first anti-rotation washer 53 are manually loosened, and the first protrusion can be freely disengaged from the first groove. At the same time, the second return spring 62 is reset under the action of external force.
[0056] Optionally, the embroidery device also includes a second pin 54 and a second return spring 62.
[0057] At least refer to Figure 2 and Figure 5 As shown, the material rack 40 is also provided with a second through hole 44 extending in the left-right direction. The second through hole 44 penetrates the second groove, and the extension direction of the second through hole 44 is perpendicular to the depth direction of the second groove. The second pin 54 is provided with a second notch, which is adapted to the second protrusion so that the second protrusion can be located within the second notch.
[0058] The second pin 54, fitted with the second return spring 62, is inserted into the second through hole 44 from right to left. The second protrusion is inserted into the second groove in the front-to-back direction and is located within the second notch. At this moment, the second return spring 62 is in a compressed state. The second fastener 55, fitted with the second anti-rotation washer 56, is threaded from left to right to the end of the second pin 54. The ear stop portion of the second anti-rotation washer 56 engages with the material rack 40 to prevent rotation. In this way, the second protrusion is locked at the second notch, improving the connection stability between the second protrusion and the second groove and avoiding the risk of the material rack 40 accidentally falling off the material rack tube 21 when the material rack 40 rotates.
[0059] When the material rack 40 is disassembled from the material rack tube 21, the second fastener 55 and the second anti-rotation washer 56 are manually loosened, and the second protrusion can be freely disengaged from the second groove. At the same time, the second return spring 62 is reset under the action of external force.
[0060] Furthermore, the second groove opening is flared, and the second protrusion end is tapered. The flared second groove opening facilitates the insertion of the second protrusion, while the tapered second protrusion end helps to gradually guide and tightly fit the second groove during insertion, thereby achieving a firm connection between the two.
[0061] Furthermore, such as Figure 2 As shown, the third groove opening is flared, and the third protrusion end is tapered. The flared third groove opening facilitates the insertion of the third protrusion, while the tapered third protrusion end helps to gradually guide and tightly fit the third groove during insertion, thereby achieving a firm connection between the two.
