Technical Field

[0001] This invention relates to the field of computerized embroidery machine technology, and in particular to a machine head for a computerized embroidery machine and the computerized embroidery machine itself. Background Technology

[0002] The ribbon embroidery device is used for embroidering ribbons and / or ropes and other ribbon-like materials.

[0003] In existing technology, a feed tray is used to feed ribbons or other strips of material to the area to be embroidered for ribbon embroidery. The feed tray is located below the machine head, and due to space constraints, its size is relatively small, requiring operators to frequently change the feed tray. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a machine head and a computerized embroidery machine in which the material tray is no longer constrained by space, allowing for increased storage capacity of ribbons, chains, ropes, etc., reducing the frequency of material changes by operators, and reducing the labor intensity of operators.

[0005] The head of a computerized embroidery machine according to an embodiment of the first aspect of the present invention includes: a needle bar and at least one auxiliary material limiting member.

[0006] The needle bar is arranged vertically;

[0008] The needle bar passes through each of the auxiliary material limiting members, and the needle bar reciprocates in the vertical direction.

[0009] When the auxiliary material limiting component is stationary, the auxiliary material limiting part is an annular channel surrounding the needle bar; or, when the auxiliary material limiting component rotates, the auxiliary material limiting part is an auxiliary material limiting through hole, so that the auxiliary material can rotate 360° around the needle bar.

[0010] In this embodiment, the auxiliary materials rotate 360° around the needle bar. On the one hand, the auxiliary material rack is no longer constrained by space, which can increase the storage capacity of auxiliary materials (such as embroidery thread, ribbon, chain, rope, etc.), reduce the frequency of auxiliary material replacement by operators, and reduce the labor intensity of operators. On the other hand, in related technologies, external devices (such as sequin devices, ribbon devices, etc.) are connected to the side wall of the machine head of the computerized embroidery machine, resulting in a relatively large machine head size and occupying a large amount of space. However, the machine head of this application is integrated with the aforementioned external devices, and the machine head of this application has the functions of the aforementioned external devices. This helps to minimize the size of the machine head of the computerized embroidery machine and avoids the excessive space occupied by a machine head with external devices.

[0015] The nozzle component is connected to an auxiliary material limiting component located near the needle bar, or the nozzle component is connected to the adapter component. In a first preset case, the adapter component rotates to allow the nozzle component to rotate around the needle bar.

[0016] According to some embodiments of the present invention, the adapter is provided with a first mating part, and the auxiliary material limiting member provided near the needle bar is provided with a second mating part.

[0019] According to some embodiments of the present invention, the third mating part is a first arc-shaped part, and the fourth mating part is a second arc-shaped part adapted to the first arc-shaped part, wherein the axis of the first arc-shaped part and the axis of the second arc-shaped part coincide with the axis of the needle bar.

[0020] Of the first arc-shaped portion and the second arc-shaped portion, one is an arc-shaped groove, and the other is an arc-shaped protrusion that fits into the arc-shaped groove. The arc-shaped protrusion fits into the arc-shaped groove.

[0021] The first mating part is a protruding post, and the second mating part is a long groove that slides with the protruding post, wherein the long groove extends in a vertical direction.

[0022] According to some embodiments of the present invention, the feed nozzle includes a feed nozzle, which is disposed corresponding to the tip of the needle of the machine needle.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0046] like Figures 1-7 As shown, the head of a computerized embroidery machine according to the first aspect of the present invention.

[0047] The head of a computerized embroidery machine includes at least one auxiliary material limiting component 20 and a needle bar 10.

[0048] The needle bar 10 is set in a vertical direction.

[0049] The auxiliary material limiting member 20 is provided with an auxiliary material limiting part, which is used to allow the auxiliary material to pass through.

[0050] The needle bar 10 passes through each of the auxiliary material limiting members 20, and the needle bar 10 reciprocates in the vertical direction. When the auxiliary material limiting member 20 is stationary, the auxiliary material limiting part is an annular channel surrounding the needle bar 10. Alternatively, when the auxiliary material limiting member 20 rotates, the auxiliary material limiting part is an auxiliary material limiting through hole, so that the auxiliary material can rotate 360° around the needle bar 10.

[0051] It should be noted that the vertical direction is the C1 direction, and the needle bar 10 reciprocates in the C1 direction.

[0052] The auxiliary material limiting component 20 can be one, two, three, etc., and this embodiment does not impose any restrictions. The auxiliary material limiting components 20 are arranged sequentially at intervals in the C1 direction.

[0053] In practical applications, such as Figure 1 As shown, the head of the computerized embroidery machine also includes an auxiliary material rack 70, which is used to set the auxiliary material roller 71. The auxiliary material is wound on the auxiliary material roller 71, such as embroidery thread, ribbon, rope, chain, sequins, etc. The auxiliary material rack 70 can be located above the needle bar 10.

[0054] In one embodiment, such as Figure 2 and Figure 5 As shown, there are two auxiliary material limiting members 20: a first auxiliary material limiting member 20a and a second auxiliary material limiting member 20b, which are substantially the same. The first auxiliary material limiting member 20a and the second auxiliary material limiting member 20b are arranged alternately in the C1 direction.

[0055] like Figure 5 As shown, the first auxiliary material limiting member 20a includes a first needle rod hole 21a and a first auxiliary material limiting part 22a, and the second auxiliary material limiting member 20b includes a second needle rod hole 21b and a second auxiliary material limiting part 22b. The needle rod 10 passes through the first auxiliary material limiting member 20a through the first needle rod hole 21a, and the needle rod 10 passes through the second auxiliary material limiting member 20b through the second needle rod hole 21b. The first needle rod hole 21a and the second needle rod hole 21b are clearance-fitted with the needle rod 10 so that the movement of the needle rod 10 along the C1 direction is not restricted or constrained by the first and second needle rod holes 10.

[0056] The first auxiliary material limiting part 22a is a first limiting through hole, and the second auxiliary material limiting part 22b is a second limiting through hole. The first and second limiting through holes are adapted to the auxiliary material so that the auxiliary material can pass through.

[0057] Under current conditions, the auxiliary material rack 70 can remain stationary. The first auxiliary material limiting member 20a and the second auxiliary material limiting member 20b rotate simultaneously, and their rotation directions and speeds can be exactly the same or approximately the same. The auxiliary material output from the auxiliary material rack 70 passes through the first and second auxiliary material limiting through holes, and the auxiliary material can rotate infinitely around the needle bar 10 clockwise or counterclockwise 360°.

[0058] When the machine head of the computerized embroidery machine is working, for example, the auxiliary materials can be embroidery thread and sequins. The embroidery thread and sequins pass through the first and second auxiliary material limiting holes, and the embroidery thread and sequins can rotate infinitely around the needle bar 10 clockwise or counterclockwise 360°. The embroidery thread passes through the needle 11 of the needle bar 10, and the needle bar 10 reciprocates in the vertical direction. The needle 11 of the needle bar 10 completes the embroidery on the sequins.

[0059] With this setup, on the one hand, the auxiliary material rack 70 is no longer constrained by space, which can increase the storage capacity of auxiliary materials (such as embroidery thread, ribbon, chain, rope, etc.), reduce the frequency of operators changing auxiliary materials, and reduce the labor intensity of operators.

[0060] On the other hand, in related technologies, external devices (e.g., sequin devices, ribbon devices, etc.) are connected to the side wall of the machine head of a computerized embroidery machine, resulting in a relatively large machine head size and occupying a significant amount of space. In contrast, the machine head of this application is integrated with the aforementioned external devices, and the machine head of this application possesses the functions of the external devices. This facilitates the miniaturization of the machine head design of the computerized embroidery machine, avoiding the excessive space occupation of a machine head with external devices.

[0061] In another embodiment, such as Figure 2 and Figure 5 As shown, there are two auxiliary material limiting members 20: a first auxiliary material limiting member 20a and a second auxiliary material limiting member 20b, which are substantially the same. The first auxiliary material limiting member 20a and the second auxiliary material limiting member 20b are arranged alternately in the C1 direction.

[0062] refer to Figure 5 The first auxiliary material limiting member 20a includes a first needle rod hole 21a and a first auxiliary material limiting part 22a, and the second auxiliary material limiting member 20b includes a second needle rod hole 21b and a second auxiliary material limiting part 22b. The needle rod 10 passes through the first auxiliary material limiting member 20a through the first needle rod hole 21a, and the needle rod 10 passes through the second auxiliary material limiting member 20b through the second needle rod hole 21b. The first needle rod hole 21a and the second needle rod hole 21b are clearance-fitted with the needle rod 10 so that the movement of the needle rod 10 along the C1 direction is not restricted or constrained by the first and second needle rod holes 10.

[0063] The first auxiliary material limiting part 22a is a first annular channel, and the second auxiliary material limiting part 22b is a second annular channel. Here, the "annular channel" penetrates the auxiliary material limiting member 20 in the C1 direction. The "annular channel" can be understood as a completely closed annular channel; it can also be understood as a non-completely closed annular channel, for example, with a small gap in the annular channel.

[0064] In the current configuration, the auxiliary material rack 70 can rotate. The auxiliary materials output from the auxiliary material rack 70 pass through the first and second auxiliary material limiting parts 22. The rotating auxiliary material rack 70 drives the auxiliary materials to rotate circumferentially along the first and second annular channels, allowing the auxiliary materials to rotate infinitely around the needle bar 10 clockwise or counterclockwise 360°. This configuration, on the one hand, frees the auxiliary material rack 70 from space constraints, increasing the storage capacity of auxiliary materials (e.g., embroidery thread, ribbon, chain, rope, etc.), reducing the frequency of auxiliary material changes by operators, and lowering the labor intensity of operators; on the other hand, it facilitates the miniaturization of the machine head design of the computerized embroidery machine, avoiding the excessive space occupied by machine heads with external attachments.

[0065] It should be noted that in the following embodiments, the first auxiliary material limiting part 22a is the first limiting through hole, and the second auxiliary material limiting part 22b is the second limiting through hole, as illustrated by the example:

[0066] In some embodiments of the present invention, when the auxiliary material limiting member 20 rotates, the head of the computer embroidery machine also includes a first transmission mechanism 40.

[0067] like Figure 2 As shown, the first transmission mechanism 40 includes a first transmission shaft 41 and at least one first transmission member 42 sleeved on the first transmission shaft 41. The first transmission shaft 41 is arranged parallel to the needle bar 10, and the first transmission member 42 is in transmission cooperation with the auxiliary material limiting member 20. With this arrangement, the rotation of the first and second auxiliary material limiting members can be realized through the first transmission mechanism 40.

[0068] In a specific embodiment, such as Figure 2 As shown, the first drive shaft 41 and the needle bar 10 are arranged in parallel. Two first drive components 42 are sleeved on the first drive shaft 41. One first drive component 42 is correspondingly arranged with the first auxiliary material limiting part 22a, and the other first drive component 42 is correspondingly arranged with the second auxiliary material limiting part 22b. One first drive component 42 is in a driving engagement with the first auxiliary material limiting part 20a, and the other first drive component 42 is in a driving engagement with the second auxiliary material limiting part 20b.

[0069] It should be noted that the "transmission coordination" mentioned above refers to one of the following: gear transmission, belt transmission, or sprocket transmission.

[0070] Preferably, one first transmission component 42 is connected to the first auxiliary material limiting component 20a via gear transmission, and the other first transmission component 42 is connected to the second auxiliary material limiting component 20b via gear transmission. This arrangement helps the first and second auxiliary material limiting components to drive the auxiliary material to rotate stably around the needle bar 10 in an infinite 360° clockwise or counterclockwise rotation. On the other hand, it shortens the overall length and width of the machine head, contributing to the miniaturization of the machine head design.

[0071] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the head of the computerized embroidery machine also includes a feed nozzle 30 and an adapter 60. The adapter 60 is connected to an auxiliary material limiting member 20 located near the needle 11 of the needle bar 10, and the two are coaxially arranged.

[0072] The nozzle component 30 is connected to the auxiliary material limiting component 20 located near the needle 11 of the needle bar 10, or the nozzle component 30 is connected to the adapter 60. In the first preset case, the adapter 60 rotates so that the nozzle component 30 rotates around the needle 11 of the needle bar 10.

[0073] It should be noted that the needle bar 10 is a cylindrical bar, and the first auxiliary material limiting member 20a and the second auxiliary material limiting member 20b are both approximately cylindrical. The needle bar 10, the first auxiliary material limiting member 20a, and the second auxiliary material limiting member 20b are coaxially arranged. The first auxiliary material limiting member 20a is located away from the needle 11 of the needle bar 10, and the second auxiliary material limiting member 20b is located closer to the needle 11 of the needle bar 10.

[0074] When the nozzle component 30 is connected to the second auxiliary material limiting component 20b, the nozzle 31 of the nozzle component 30 is set to correspond to the needle tip of the needle 11.

[0075] The self-rotating first auxiliary material limiting member 20a causes the nozzle member 30 to rotate around the needle 11 of the needle bar 10. The auxiliary material passes through the first and second limiting through holes and is then output from the nozzle 31 of the nozzle member 30 to the needle tip of the needle 11. This allows the auxiliary material to smoothly transition to the needle tip of the needle 11, preventing the auxiliary material from getting stuck.

[0076] like Figure 3 and Figure 4 As shown, the nozzle component 30 is connected to the adapter component 60. The adapter component 60 is connected to the second auxiliary material limiting component 20b, and has a through hole 61. The adapter component 60 can be fitted onto the side wall of the second auxiliary material limiting component 20b through the through hole 61, so that the two are coaxially arranged. The nozzle 31 of the nozzle component 30 corresponds to the needle tip of the needle 11. It should be noted that the adapter component 60 can also be located below the second auxiliary material limiting component 20b. At the current moment, the center of the through hole 61 of the adapter component 60 is coaxially arranged with either the second auxiliary material limiting component 20b or the needle bar 10.

[0077] In the first preset condition, the self-rotating adapter 60 causes the nozzle component 30 to rotate around the needle 11 of the needle bar 10. The auxiliary material passes through the first and second limiting through holes and is then output from the nozzle 31 of the nozzle component 30 to the needle tip of the needle 11. This allows the auxiliary material to smoothly transition to the needle tip of the needle 11, preventing the auxiliary material from getting stuck.

[0078] Furthermore, such as Figure 4 As shown, the adapter 60 is provided with a first mating part 63, and the auxiliary material limiting member 20 provided near the needle 11 of the needle bar 10 is provided with a second mating part 23. The second mating part 23 and the first mating part 63 are interlocked to make the rotating auxiliary material limiting member 20 drive the adapter 60 to rotate under a first preset condition.

[0079] In a specific embodiment, the second auxiliary material limiting member 20b is provided with a second mating part 23, which is a groove. The adapter 60 is provided with a first mating part 63, which is a protrusion that fits into the groove. The rotating second auxiliary material limiting member 20b drives the adapter 60 to rotate. This enables the adapter 60 to rotate under a first preset condition, thereby driving the nozzle member 30 to rotate around the needle 11 of the needle bar 10.

[0080] Furthermore, such as Figure 4 As shown, the head of the computer embroidery machine also includes a second transmission mechanism 50, which includes a second transmission component 52 that reciprocates in the vertical direction.

[0081] The second transmission member 52 is provided with a third mating part 521, and the adapter 60 is also provided with a fourth mating part 62. The third mating part 521 and the fourth mating part 62 cooperate to make the adapter 60 reciprocate in the vertical direction under the second preset condition.

[0082] In a specific embodiment, such as Figure 4 As shown, the second mating part 23 is an elongated groove, the extension direction of which is vertical, and the protrusion can slide along the extension direction of the elongated groove.

[0083] The second transmission mechanism 50 includes a second link assembly 51 and a second transmission member 52. The second link assembly 51 causes the second transmission member 52 to reciprocate in the vertical direction.

[0084] like Figure 4 As shown, the second transmission component 52 is provided with a third mating part 521, and the adapter 60 is also provided with a fourth mating part 62. The third mating part 521 is a first arc-shaped part, and the fourth mating part 62 is a second arc-shaped part that is adapted to the first arc-shaped part. The axis of the first arc-shaped part and the axis of the second arc-shaped part coincide with the axis of the needle bar 10.

[0085] One of the first arc-shaped portion and the second arc-shaped portion is an arc-shaped groove, and the other is an arc-shaped protrusion that fits into the arc-shaped groove. The arc-shaped protrusion fits into the arc-shaped groove.

[0086] like Figure 6 and Figure 7 As shown, the second transmission member 52, which reciprocates vertically, allows the adapter 60 to also reciprocate vertically in the second preset condition through the interlocking arc-shaped protrusion and arc-shaped groove. Simultaneously, in the first preset condition, the adapter 60 can also rotate due to the guiding effect between the arc-shaped protrusion and arc-shaped groove. Therefore, the adapter 60 can freely switch between the first and second preset conditions, and the rotational movement of the adapter 60 and its reciprocating vertical movement will not interfere with each other.

[0087] Correspondingly, the nozzle 30 connected to the adapter 60 can rotate around the needle 11 of the needle bar 10, and the nozzle 30 can also reciprocate in the vertical direction. At this time, the nozzle 31 of the nozzle 30 is equivalent to the presser foot in the related technology. The nozzle 31 has the function of a presser foot, and the nozzle 31 can contact the fabric thread.

[0088] In some embodiments of the present invention, the head of the computer embroidery machine also includes an auxiliary material rack 70, which is located above the needle bar 10.

[0089] When the first and second auxiliary material limiting parts are both stationary or rotating, the auxiliary material rack 70 can rotate independently. This setting helps the auxiliary material output from the auxiliary material rack 70 to rotate stably around the needle bar 10360°.

[0090] Or, such as Figure 2 As shown, when the first and second auxiliary material limiting components rotate, the auxiliary material frame 70 includes an auxiliary material roller 71 and a frame 72 supporting the auxiliary material roller 71. The frame 72 includes a base 722 and a support frame 721, and the support frame 721 is connected to the base 722.

[0091] The first transmission mechanism 40 includes three first transmission components 42 and a first transmission shaft 41. The three first transmission components 42 are sleeved on the first transmission shaft 41. One first transmission component 42 is correspondingly disposed with the first auxiliary material limiting part 22a, another first transmission component 42 is correspondingly disposed with the second auxiliary material limiting part 22b, and yet another first transmission component 42 is correspondingly disposed with the base 722.

[0092] One first transmission component 42 is connected to the first auxiliary material limiting component 20a by gear transmission, another first transmission component 42 is connected to the second auxiliary material limiting component 20b by gear transmission, and yet another first transmission component 42 is connected to the base 722 by gear transmission. With this configuration, the auxiliary material rack 70 can rotate on its own via the first transmission mechanism 40, which helps the auxiliary material output from the auxiliary material rack 70 to rotate stably around the needle bar 10360°.

[0093] Furthermore, such as Figure 5 As shown, the base 722 is provided with a material passage hole 7221, which is aligned vertically with the material limiting part 22. This arrangement allows the material passing through the material passage hole 7221 and the first and second limiting holes of the base 722 to move vertically, which is beneficial for the material to pass smoothly through the first and second limiting holes.

[0094] The computerized embroidery machine according to the second aspect of the present invention includes the machine head of the computerized embroidery machine of the first aspect.

[0095] This computerized embroidery machine has the advantages of a computerized embroidery machine head. On the one hand, the auxiliary material rack 70 is no longer constrained by space, which can increase the storage capacity of auxiliary materials (such as embroidery thread, ribbon, chain, rope, etc.), reduce the frequency of operators changing auxiliary materials, and reduce the labor intensity of operators. On the other hand, it helps to make the machine head of the computerized embroidery machine smaller, avoiding the machine head with external devices occupying too much space.
