[0062] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For purposes of simplicity of the present disclosure, the description below generally is directed with reference to particular examples. However, the teachings of the present application extend to other examples and uses that are apparent to those of ordinary skill in the art. For example, it should be understood that the drawings and detailed description thereto are not necessarily to scale as the drawings are only intended to constitute an illustrative representation of potential embodiments. Also, the specific materials and dimensions of the various components are not to be construed as limiting. Rather, the present application is intended to embrace all known and later-developed equivalents and / or modifications. Moreover, the present application expressly applies to all related selected embodiments and their equivalents.

[0063] As shown in Figures 1-16 , a head of a computerized embroidery machine according to a first aspect of the present application.

[0064] A head of a computerized embroidery machine comprises a needle bar 10, a gold piece external hanging mechanism 110, and at least one auxiliary material limiting piece.

[0065] The needle bar 10 is arranged along a vertical direction, and the needle bar 10 can reciprocate in the vertical direction.

[0066] The auxiliary material limiting piece can rotate. The auxiliary material limiting piece is provided with a needle bar hole and an auxiliary material limiting through hole, and the needle bar 10 passes through the needle bar hole and is in clearance fit with the needle bar hole.

[0067] The gold piece external hanging mechanism 110 is connected to the auxiliary material limiting piece arranged near the needle 11 of the needle bar 10, and the gold piece external hanging mechanism 110 rotates around the needle 11 of the needle bar 10.

[0068] It should be noted that the vertical direction is the C1 direction, and the needle bar 10 reciprocates in the C1 direction.

[0069] The auxiliary material limiting piece 20 can be one, two, three, etc., and the present embodiment is not limited. Each auxiliary material limiting piece is arranged in sequence and spaced apart in the C1 direction.

[0070] In actual application, as shown in Figure 1 , the head of the computerized embroidery machine further comprises an auxiliary material rack 70, and the auxiliary material rack 70 is used to arrange an auxiliary material roller 71, and the auxiliary material roller 71 is wound with auxiliary material, for example, the auxiliary material can be embroidery thread, ribbon, rope, chain, gold piece belt, etc. The auxiliary material rack 70 can be located above the needle bar 10.

[0071] In a specific embodiment, as shown in Figure 2 , two auxiliary material limiting pieces are provided: a first auxiliary material limiting piece 20a and a second auxiliary material limiting piece 20b, and the first auxiliary material limiting piece 20a and the second auxiliary material limiting piece 20b are arranged in sequence and spaced apart in the C1 direction.

[0072] As shown in Figure 1As shown, the gold sheet external hanging mechanism 110 is located below the second auxiliary material limiting piece 20b, and the gold sheet external hanging mechanism 110 is connected to the second auxiliary material limiting piece 20b. In this way, the space between the adjacent two machine heads is avoided, thereby the space between the adjacent two machine heads can be compressed, which helps to increase the number of machine heads on the beam.

[0073] As shown in the drawings, Figure 4 As shown, the first auxiliary material limiting piece 20a includes a first needle rod hole and a first auxiliary material limiting through hole, and the second auxiliary material limiting piece 20b includes a second needle rod hole 21b and a second auxiliary material limiting through hole 22b. The needle rod 10 passes through the first auxiliary material limiting piece through the first needle rod hole, and the needle rod 10 passes through the second auxiliary material limiting piece 20b through the second needle rod hole 21b. The first needle rod hole and the second needle rod hole 21b are in clearance fit with the needle rod 10, so that the movement of the needle rod 10 in the C1 direction is not limited or restricted by the first and second needle rod 10 holes.

[0074] The auxiliary material rack 70, the first auxiliary material limiting piece 20a, and the second auxiliary material limiting piece 20b rotate simultaneously, and the rotation direction and speed of the auxiliary material rack 70, the first auxiliary material limiting piece 20a, and the second auxiliary material limiting piece 20b can be completely or approximately the same. The gold sheet belt output from the auxiliary material rack 70 passes through the first and second auxiliary material limiting through holes, and the gold sheet belt can rotate 360° infinitely around the needle rod 10 clockwise or counterclockwise.

[0075] The second auxiliary material limiting piece 20b rotates, driving the gold sheet external hanging mechanism 110 to rotate.

[0076] In operation, the auxiliary material rack 70, the first auxiliary material limiting piece 20a, and the second auxiliary material limiting piece 20b enable the gold sheet belt to rotate 360° infinitely around the needle rod 10 clockwise or counterclockwise, the gold sheet is conveyed to the place to be embroidered, the needle 11 lowers to pierce the fabric, and the thread locks the gold sheet on the fabric.

[0077] In addition, as shown in the drawings, Figure 15 As shown, a schematic diagram of gold sheet embroidery in the prior art is shown. Figure 16 The gold sheet embroidery schematic diagram of the embodiment of the present application. The gold sheet device 110 in the embodiment can rotate 360°, and the gold sheet J2 embroidered by the gold sheet device 110 can select a suitable position according to requirements, that is, the gold sheet J1 embroidery position in the prior art is different, and the gold sheet J1 embroidery position is fixed. Through the 360° rotation of the gold sheet device 110, the gold sheet embroidery position on the pattern can be moved, which can be designed according to requirements, thereby improving the presentation effect of the pattern.

[0078] In summary, the gold piece external hanging mechanism 110 is connected to the auxiliary material limiting piece arranged near the needle 11 of the needle bar 10, which avoids occupying the space between the adjacent two heads, and thus can compress the space between the adjacent two heads, which helps to increase the number of heads on the beam; the gold piece embroidery position of the pattern can be moved, which is designed according to the demand, and thus the pattern presentation effect is improved.

[0079] As shown in Figures 11-14 In some embodiments of the application, the head of the computer embroidery machine further comprises an external hanging driving piece 140 arranged on the auxiliary material limiting piece near the needle 11 of the needle bar 10, and the external hanging driving piece 140 can rotate around the needle bar 10.

[0080] The gold piece external hanging mechanism 110 includes a dial piece assembly 1103 and a cutter assembly 1104, the dial piece assembly 1103 includes a dial piece rod 11031, the cutter assembly 1104 includes a cutter 11041, the external hanging driving piece 140 moves the dial piece rod 11031, and the external hanging driving piece 140 moves the cutter 11041.

[0081] It should be noted that in this way, the gold piece external hanging mechanism 110 can avoid setting a motor to drive the dial piece rod 11031 or the cutter 11041 to move, which can reduce the weight of the gold piece external hanging mechanism 110, and thus reduce the load of the auxiliary material limiting piece, which is conducive to the high-speed rotation of the auxiliary material limiting piece. At the same time, the external hanging driving piece 140 can stably drive the cutter 11041 and the dial piece rod 11031 to move.

[0082] In some embodiments of the application, the computer embroidery machine further comprises a fifth transmission mechanism 120.

[0083] As shown in Figures 2-6 The fifth transmission mechanism 120 includes a fifth connecting piece 122 and a fifth transmission piece 121, and the fifth transmission piece 121 is arranged above and below the second auxiliary material limiting piece 20b. The second auxiliary material limiting piece 20b is also provided with a driving piece mounting hole 24. The external hanging driving piece 140 is connected to the surface of the fifth transmission piece 121 facing the auxiliary material limiting piece, the external hanging driving piece 140 passes through the second auxiliary material limiting piece 20b through the driving piece mounting hole 24, and part of the external hanging driving piece 140 is exposed from the driving piece mounting hole 24. The fifth connecting piece 122 is provided with a motor, which provides power for the vertical reciprocating movement of the fifth connecting piece 122.

[0084] The fifth connecting piece 122 is provided with an arc-shaped protrusion 1221, and the fifth transmission piece 121 is provided with an arc-shaped groove 1213, and the arc-shaped groove 1213 is embedded and inserted with the arc-shaped protrusion 1221. The axis of the arc-shaped protrusion 1221 and the axis of the arc-shaped groove 1213 coincide with the axis of the needle bar 10.

[0085] When the fifth connecting piece 122 is static, the arc-shaped protrusion 1221 guides the arc-shaped groove 1213 to guide the rotation of the fifth transmission member 121.

[0086] When the fifth connecting piece 122 reciprocates in the vertical direction, the arc-shaped groove 1213 and the arc-shaped protrusion 1221 are embedded and matched to drive the fifth transmission member 121 to reciprocate in the vertical direction, and then the external hanging driving member 140 can also reciprocate in the vertical direction.

[0087] When the fifth transmission mechanism 120 works, the second auxiliary material limiting piece 20b rotates around the needle rod 10, and then the fifth transmission member 121 also rotates. When the fifth connecting piece 122 is static, the arc-shaped protrusion 1221 guides the arc-shaped groove 1213 to guide the rotation of the fifth transmission member 121. If the fifth connecting piece 122 reciprocates in the vertical direction, the arc-shaped groove 1213 and the arc-shaped protrusion 1221 are embedded and matched to drive the fifth transmission member 121 to reciprocate in the vertical direction, and then the external hanging driving member 140 can also reciprocate in the vertical direction. Therefore, the external hanging driving member 140 can rotate around the needle rod 10 and also reciprocate in the vertical direction, and the two movements do not interfere with each other.

[0088] Further, the fifth transmission member 121 is also provided with an auxiliary material avoiding hole 1211 and a needle rod avoiding hole 1212. The needle rod 10 passes through the needle rod avoiding hole 1212, and the auxiliary material avoiding hole 1211 is arranged opposite to the second auxiliary material limiting through hole 22. In this way, the needle rod 10 and the auxiliary material pass through the fifth transmission member 121, and the fifth transmission member 121 avoids interfering with the needle rod 10 and the auxiliary material.

[0089] In some embodiments of the present application, the external hanging driving member 140 has a slice position, an initial position and a slice position arranged in sequence in the vertical direction.

[0090] When the external hanging driving member 140 is in the slice position, the external hanging driving member 140 drives the slice rod 11031 to move; when the external hanging driving member 140 is in the slice position, the external hanging driving member 140 drives the cutter 11041 to move.

[0091] In specific embodiments, as shown in Figures 11-14 The gold sheet external hanging mechanism 110 includes a gold sheet external hanging frame 1101 and a gold sheet guide frame 1102, and the gold sheet guide frame 1102 is connected to the gold sheet external hanging frame 1101. The gold sheet band passing through the second auxiliary material limiting through hole 22b passes through each gold sheet guide hole of the gold sheet guide frame 1102 to the preset position of the gold sheet external hanging frame 1101, so as to cooperate with the slice assembly 1103.

[0092] The dial piece assembly 1103 comprises a dial piece rod 11031 and a dial piece connecting rod assembly 11032. The dial piece connecting rod assembly 11032 is composed of a plurality of connecting rods, and the number of the connecting rods is not limited in the embodiment. The dial piece rod 11031 is connected to the dial piece connecting rod assembly 11032, and the dial piece connecting rod assembly 11032 is connected to the gold sheet outer hanging rack 1101.

[0093] As shown in FIG. 6, when the outer hanging driving element 140 is in the dial piece position, the outer hanging driving element 140 is in contact with the dial piece connecting rod assembly 11032, the outer hanging driving element 140 drives the dial piece connecting rod assembly 11032 to move, and then the dial piece rod 11031 moves, the dial piece rod 11031 drives the gold sheet belt to move, so that a gold sheet is in the preset cutting position. Figure 13

[0094] The cutter assembly 1104 comprises a driving block 11043, a cutter shaft 11042 and a cutter 11041. The cutter 11041 is connected to the end of the cutter shaft 11042, and the driving block 11043 is provided with a cutter shaft hole, through which the driving block 11043 is sleeved on the cutter shaft 11042. If the driving block 11043 swings along the circumference of the cutter shaft 11042, the driving block 11043 drives the cutter shaft 11042 to swing relative to the axis of the cutter shaft 11042, and then the cutter 11041 can swing.

[0095] The gold sheet outer hanging rack 1101 is further provided with a mounting shaft cavity 11011, and a mounting block hole 11012 is formed in the side wall of the mounting shaft cavity 11011. The mounting block hole 11012 is in communication with the mounting shaft cavity 11011. The driving block 11043 is arranged in the mounting block hole 11012, and part of the driving block 11043 protrudes out of the mounting block hole 11012. The cutter shaft 11042 is arranged in the mounting shaft cavity 11011 and passes through the cutter shaft hole. The cutter 11041 is located in the preset cutting position.

[0096] As shown in FIG. 6, when the outer hanging driving element 140 is in the cutting position, the outer hanging driving element 140 abuts against the protruding part of the driving block 11043 through the transition swing rod 1105 to make the driving block 11043 deflect, and the cutter 11041 deflects to cut off the gold sheet on the gold sheet belt. Figure 14

[0097] In this way, the cutter 11041 and the dial piece rod 11031 can be driven to move simultaneously by the reciprocating movement of the outer hanging driving element 140 in the vertical direction, so that an additional driving mechanism is avoided, which helps to reduce the production cost. Meanwhile, the dial piece position, the initial position and the cutting position are arranged in sequence in the vertical direction, which helps the outer hanging driving element 140 to drive the cutter 11041 and the dial piece rod 11031 to move stably and accurately.

[0098] ​​It should be noted that the cutter 11041 of the cutter assembly 1104 and the lever 11031 of the lever assembly 1103 are restored to their initial positions by a torsion spring or a tension spring.

[0099] In some embodiments of the present invention, the head of the computerized embroidery machine further includes a sixth transmission mechanism 130. The sixth transmission mechanism 130 includes a sixth transmission member 131, which is connected to the second auxiliary material limiting member 20b. Under a third preset condition, the sixth transmission member 131 reciprocates in the vertical direction.

[0100] like Figures 7-10 As shown, in practical applications, the head of a computerized embroidery machine also includes a feed nozzle 30, a second transmission mechanism 50, and an adapter 60. The adapter 60 is sleeved on the second auxiliary material limiting member 20b, and the two are coaxially arranged. The feed nozzle 30 is connected to the adapter 60.

[0101] The second transmission mechanism 50 includes a second transmission member 52, and the cooperation between the second transmission member 52 and the adapter 60 is described above with reference to the description of the fifth connector 122 and the fifth transmission member 121.

[0102] An arc-shaped protrusion and an arc-shaped groove are also provided between the second auxiliary material limiting member 20b and the adapter 60. Under the first preset condition, the adapter 60 can rotate by means of the guiding effect between the arc-shaped protrusion and the arc-shaped groove. The second transmission member 52, which reciprocates in the vertical direction, can cause the adapter 60 to also reciprocate in the vertical direction under the second preset condition.

[0103] Furthermore, the adapter 60 and the second auxiliary material limiting member 20b are fitted with a clearance. The sixth transmission member 131 is connected to the second auxiliary material limiting member 20b. In the third preset condition, the sixth transmission member 131 reciprocates in the vertical direction, thereby adjusting the height of the second auxiliary material limiting member 20b in the vertical direction. Correspondingly, the height of the gold sheet hanging mechanism 110 connected to the second auxiliary material limiting member 20b in the vertical direction can also be adjusted.

[0104] This configuration allows for adjustment of the vertical height of the sequin hanging mechanism 110, enabling the adjustment of the distance between the sequin hanging mechanism 110 and the fabric. When the fabric embroidery is complete and a new fabric needs to be replaced, the sequin hanging mechanism 110 is raised to facilitate the replacement.

[0105] It should be noted that the sixth transmission mechanism 130 also includes a cylinder mechanism 132 connected to the sixth transmission member 131, and the cylinder mechanism 132 drives the sixth transmission member 131 to reciprocate in the vertical direction.
