The routing unit 1 selects the mounting position on the mounting board 2 to match the corresponding upper routing hole 41 and lower routing hole 51 for routing.
The wiring unit 1 comprises a wiring board 11 and a wiring rod 13, wherein the wiring board 11 is in a substantially horizontal state, so that the mounting plate 2 and the wiring board 11 are in a substantially vertical state. Walk left and right both sides edge of line board 11 and downwardly extending respectively and form two locating plates 12, install respectively on two locating plates 12 at the both ends of wire winding pole 13 to support the tip of wire winding pole 13 through two locating plates 12, make wire winding pole 13 rotate on walking line board 11 simultaneously. Wherein all winding rods 13 are coaxially arranged.
The wiring board 11 is provided with a first wiring hole 111, a second wiring hole 112 and a third wiring hole 113. By way of example, one of the wiring units 1 and the corresponding upper wiring hole 41 and the corresponding lower wiring hole 51 are illustrated, the upper wiring hole 41 and the lower wiring hole 51 are both located above the wiring board 11, the winding rod 13 is located below the wiring board 11, a silk thread sequentially passes through the upper wiring hole 41 and the first wiring hole 111 to reach the lower part of the wiring board 11, then bypasses the winding rod 13 from the bottom of the winding rod 13 through the second wiring hole 112 and then goes downward to the wiring hole 51, and finally sequentially passes through the lower wiring hole 51 and the third wiring hole 113. Wherein the bottom of the winding rod 13 is always in contact with the silk thread, so that the silk thread can drive the winding rod 13 to rotate when the silk thread is pulled. The part of the silk thread at the position of the thread winding rod 13 is limited between the two positioning plates 12, so that the silk thread can not contact with the thread winding rods 13 of other thread winding units 1 and can not contact with the silk threads on other thread winding rods 13 to be wound, the thread breakage rate is effectively reduced, the loss of the silk thread is reduced, the shutdown frequency of the embroidery machine can be correspondingly reduced, and the production efficiency of the embroidery machine can be improved.

Each winding rod 13 is independent of each other and hardly interferes with each other, so that the rotation of different winding rods 13 can be synchronous or asynchronous. Correspondingly, the drawing speeds of different threads can be the same or different, so that the working process of the embroidery machine is less limited, and the working action design is more diversified.
In order to adjust the installation position of the wiring unit 1 on the installation plate 2 conveniently and match with the specific upper wiring hole 41 and the specific lower wiring hole 51, the front side surface of the installation plate 2 is provided with a dovetail groove 21 extending along the axial direction of the winding rod 13, the wiring unit 1 further comprises a guide plate 14 fixed on the rear side edge of the wiring plate 11, and the shape of the guide plate 14 is matched with that of the dovetail groove 21, so that the guide plate 14 is arranged at the position of the dovetail groove 21 in a sliding mode, and the position of the wiring unit 1 is adjusted in the axial direction of the dovetail groove 21. Both ends of the dovetail groove 21 are penetrated so that the guide plate 14 can slide into the dovetail groove 21 from an opening at the end of the dovetail groove 21.
Preferably, in the same routing unit 1, the guiding plate 14 is located between the two positioning plates 12, so as to avoid the guiding plate 14 increasing the overall width of the routing unit 1. Further, the guiding plate 14 is fixed to the edges of the two positioning plates 12 at the same time, so that the guiding plate 14 and the positioning plates 12 are matched with each other, the connection strength on the guiding plate 14 is enhanced, and the deformation of the top edge of the guiding plate 14 and the top edge of the positioning plate 12 on the bottom surface of the wiring plate 11 is suppressed, thereby stabilizing the position stability of the mounting plate 2 and the winding rod 13 on the mounting plate 2.
The increased length of the mounting board 2 allows it to mount more routing units 1. Generally, adjacent routing units 1 are jointed and spliced with each other, and the routing unit group formed by all the routing units 1 moves on the mounting plate 2 along the axial direction of the dovetail groove 21 to perform position adjustment. After the position of the wiring unit 1 on the mounting plate 2 is adjusted, the fixture blocks 211 are simultaneously arranged at two ends of the dovetail groove 21, the fixture blocks 211 are clamped in the dovetail groove 21 to obtain positioning, and simultaneously, the two fixture blocks 211 are respectively pressed on the wiring unit group from the left side and the right side, so that the whole wiring unit group is positioned in the axial direction of the dovetail groove 21. The latch 211 can be detached from the mounting plate 2 after being taken out from the end of the dovetail groove 21.
In some cases, as in the present embodiment, the dovetail groove 21 is not filled enough by only relying on the routing unit set and the latch 211, and at this time, the latch 211 can only move a certain distance from the end of the dovetail groove 21 to be pressed on the end of the routing unit set. However, since the degree of deformation of the block 211 in the dovetail groove 21 is large, the frictional force with the inner wall of the dovetail groove 21 is large, and it is difficult to move the block in the dovetail groove 21. Therefore, the wiring mechanism in this embodiment further includes the filling block 16, the filling block 16 is located between the fixture block 211 and the wiring unit group, the fixture block 211 is pressed at the end of the wiring unit group through the filling block 16, the wiring unit group and the fixture block 211 are matched with the filling block 16 to fill the dovetail groove 21, so that the fixture block 211 is located at the end of the dovetail groove 21, the fixture block 211 does not need to be moved to the middle position of the dovetail groove 21, and the installation difficulty of the fixture block 211 is reduced.
The lower pressure level is kept between the wiring unit 1 and the filling block 16 and the inner wall of the dovetail groove 21, so that the movement of the wiring unit 1 and the filling block 16 at the dovetail groove 21 is in a low friction state, and the installation difficulty of the wiring unit 1 and the filling block 16 is reduced.
In the same wire routing unit 1, in order to facilitate the wire winding rod 13 to be disassembled and assembled between the two positioning plates 12, the disassembling and assembling hole 121 is formed in at least one positioning plate 12, the end portion of the wire winding rod 13 is located in the disassembling and assembling hole 121, the edge of the disassembling and assembling hole 121 can support and position the end portion of the wire winding rod 13, and the same wire winding rod 13 can axially move in the disassembling and assembling hole 121 to complete the disassembling and assembling action.
After the winding rod 13 is installed between the two positioning plates 12, a blocking piece 122 needs to be installed at the outer opening of the dismounting hole 121, and the blocking piece 122 is attached to the end surface of the winding rod 13, so that the winding rod 13 is prevented from falling out of the dismounting hole 121.
As one of the installation methods of the blocking piece 122, the outer side surface of the positioning plate 12 provided with the dismounting hole 121 is recessed to form a slot 123, and the blocking piece 122 is clamped in the slot 123, so that the blocking piece 122 is not driven to rotate when one of the winding rods 13 rotates, thereby preventing interference to the rotation process of the adjacent winding rod 13. In addition, after the wiring unit 1 is removed from the mounting board 2, the blocking piece 122 can be ejected out of the slot 123 by pushing the winding rod 13.
In this embodiment, in the same wire routing unit 1, the outer side surface of the positioning plate 12 on the right side is provided with a positioning rib 124, and the outer side surface of the positioning plate 12 on the left side is provided with a positioning groove 125 matched with the positioning rib 124 in shape. Therefore, in two adjacent wiring units 1, the positioning rib 124 of the left wiring unit 1 can be inserted into the positioning groove 125 of the right wiring unit 1, so that the two wiring units 1 are attached more tightly, the positioning effect of the relative position between the two wiring units 1 is improved, and the two adjacent wiring units 1 are prevented from shaking relatively.
The wire-passing board 11 has a first dividing plane perpendicular to the wire-winding rod 13, and the lower wire-passing hole 51 is located in the first dividing plane. The first wire feeding hole 111 and the second wire feeding hole 112 are located on one side of the first boundary plane, and the third wire feeding hole 113 is located on the other side of the first boundary plane, so that the contact length between a silk thread and the winding rod 13 is reduced, the resistance of the winding rod 13 to the silk thread is reduced, and meanwhile, the silk thread can smoothly pass through the lower wire feeding hole 51 from the second wire feeding hole 112 to reach the third wire feeding hole 113.
Preferably, the wire guide plate 11 further has a second dividing plane parallel to the winding rod 13 and perpendicular to the first dividing plane, the first wire guide hole 111 is located on one side of the second dividing plane, and the second wire guide hole 112 and the third wire guide hole 113 are located on the other side of the second dividing plane, so that the portion of the wire located between the first wire guide hole 111 and the bottom of the winding rod 13 and the portion of the wire located below the third wire guide hole 113 are staggered, so as to avoid the twisting of the portion of the wire located below the wire guide plate 11 as much as possible.
In addition, anti-slip sleeves are sleeved in the first wire running hole 111 and the third wire running hole 113, so that the tension state of the silk thread is maintained in the process of passing from the first wire running hole 111 to the third wire running hole 113. The second thread hole 112 is shaped as a long groove, thereby leaving a certain movement space for the thread during the movement of the thread take-up lever 5 to prevent the thread from breaking.
Example 2:
when the take-up lever moves too fast, the thread on the winding lever 13 may be caused to move down and away from between the two positioning plates 12, and the thread may be accompanied by strong vibration. The silk thread not only easily takes place to twine with other silk threads and leads to breaking apart after leaving between two locating plates 12, in addition the silk thread still easily produces too strong collision between the pole 13 that winds after restoreing, leads to the silk thread to break apart.
In order to solve the above problem, referring to fig. 11, the wire routing unit of the present embodiment further includes a wire blocking rod 15 located below the wire winding rod 13, and the wire blocking rod 15 is located between the two positioning plates 12. When the wire leaves the winding rod 13 and moves downwards, if the wire moves too far, the wire is blocked by the wire blocking rod 15, so that the wire blocking rod 15 can effectively limit the wire at the winding rod 13 between the two positioning plates 12. In addition, because the distance of the silk thread from the winding rod 13 is effectively limited, the impact force between the silk thread and the winding rod 13 when the silk thread is reset to the winding rod 13 is not too large, and the silk thread is not easy to break after being reset. The end of the wire blocking rod 15 can be mounted on the positioning plate 12 so as to obtain a supporting positioning.
The shapes and relative spatial arrangements of the first wiring hole 111, the second wiring hole 112 and the third wiring hole 113 of the wiring board 11 of the present embodiment are consistent with those of embodiment 1, so that the positioning plate 12 on the left side is adjacent to the third wiring hole 113, and the positioning plate 12 on the right side is adjacent to the second wiring hole 112.
The silk thread of walking line board 11 below is mainly located the below of second line hole 112, therefore the right-hand member of fender line pole 15 is fixed on locating plate 12 on right side to make fender line pole 15 be located the below of second line hole 112, in order to ensure that fender line pole 15 can play limiting displacement to the silk thread of walking line board 11 below. And a gap is left between the left end of the thread blocking rod 15 and the left positioning plate 12 so as to facilitate threading at the first thread passing hole 111, the second thread passing hole 112 and the third thread passing hole 113 in the initial operation stage of the embroidery machine.
While the utility model has been described with reference to specific embodiments thereof, it will be understood by those skilled in the art that the utility model is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the utility model as set forth in the following claims.
