It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.
Referring to fig. 1 to 7, the embroidery machine includes an embroidery machine head, wherein the embroidery machine head includes a head housing assembly 200 and a needle bar frame assembly 100, the head housing assembly 200 includes a head housing, a cam link mechanism, etc., a thread hooking device 2 is installed on the head housing, the thread hooking device 2 includes a thread hooking device 21, and the needle bar frame assembly 100 includes a needle bar frame and is further provided with a needle bar driving device 1. Reference may be made in particular to the prior art.
For leather and other thick cloth (leather), in order to change the leather, the height requirement from the lower end of the machine shell to the needle plate surface is higher than that of a common embroidery machine, so that the position of the shuttle box body in the height direction can be reduced. Meanwhile, in order to compensate for the reduction of the height position of the shuttle box body, the smooth embroidery is ensured by lengthening the needle rod. The needle bar is behind the extension, and the high position of bottom dead center can promote during the parking state, even if the needle bar driver moves when the highest position during consequently the rise of the needle, its draw-in groove still can not bump lower dead center. Therefore, the utility model discloses an embroidery machine needle bar drive arrangement can down press the needle bar when the rising, makes in the lower dead center embedding drive block draw-in groove on the needle bar.
Referring to fig. 2 to 5, the needle bar driving device 1 of the embroidery machine includes a needle bar 14 having an upper dead point 142 and a lower dead point 141, a needle bar driver 15 driving the needle bar 14 to move, the needle bar driver 15 including a needle bar driving block 151, the needle bar driving block 151 being provided with a catching groove 1511 cooperating with the lower dead point 141.
In order to press the needle bar 14 downward at the time of raising, the embroidery machine needle bar driving device 1 further includes a needle bar assembly which presses the needle bar 14 downward at the time of raising so that the lower dead point 141 corresponds to the height of the catching groove 1511. When the needle is drawn up, the needle bar 14 is pressed downwards by the needle bar pressing component, so that the lower dead point 141 corresponds to the height of the clamping groove 1511, the needle bar driving block 151 can rotate to enable the lower dead point 141 to be embedded into the driving block clamping groove 1511, and the needle bar 14 can move up and down along with the needle bar driver 15.
In this embodiment, the needle bar pressing assembly includes a needle bar pressing rod 11 for pressing down the top dead center 142 and a driving member for driving the needle bar pressing rod 11 to move, and the upper cross beam 101 of the needle bar frame is provided with a guide hole matched with the needle bar pressing rod 11 for guiding the needle bar pressing rod 11 to move linearly up and down.
In order to perform a pressing action with the upper stop point 142, a pressing plate 111 which is pressed with the upper stop point 142 is arranged at the bottom of the needle rod pressing rod 11, and two limiting holes 1111 are arranged on the pressing plate 111 and are respectively matched with the needle rod 14 and the guide rod (the guide rod is arranged side by side with the needle rod), so that the needle rod pressing rod 11 is prevented from rotating. By means of the upper dead point 142 inherent on the existing needle bar, the needle bar 14 is pressed downwards in a mode that the pressing plate 111 presses the upper dead point 142, and a pressing fulcrum is not required to be additionally arranged on the needle bar.
In addition, the needle bar pressing rod 11 is connected with a return spring which can realize upward return after the pressing plate is disengaged from the upper stop point 142. The needle bar pressing assembly further comprises a swinging shaft 16 and a swinging rod 12 rotatably connected to the swinging shaft 16, and the needle bar pressing rod 11 is driven by the swinging rod 12. The swing lever 12 is forced to rotate around the swing shaft 16, so that the needle bar pressing lever 11 is pressed downwards, the needle bar pressing lever 11 pushes the upper dead point 142 downwards after descending, and the lower dead point 141 on the needle bar is embedded into the clamping groove 1511 of the driving block. After the pressing action is completed, the needle bar pressing rod 11 is reset upwards through the reset spring after the pressing plate 111 is disengaged from the upper stop point 142, and then the needle bar 14 can work normally. The needle rod pressing rod 11 can lift the swing rod 12 to rotate and reset, so that the swing rod can be driven to rotate around the swing shaft through simple horizontal linear extension.
The pressing needle rod assembly further comprises an air cylinder 13, and the swinging rod 12 is driven to rotate through the extension and contraction of a piston rod of the air cylinder 13. No complex transmission structure is required.
The swing lever 12 is provided with a rear projection projecting rearward, to which a rear rolling bearing 122 is attached. The swing lever 12 is provided with a swing head 121 projecting forward. The upper end of the needle rod pressing rod 11 is connected with an upper rolling bearing 112, and the swinging head 121 is provided with an arc surface matched with the rolling bearing. The rolling contact is realized by adopting the rolling bearing, the friction force is smaller, the transmission is smoother, and the noise is smaller.
In addition, when the shuttle box body is lowered, the conventional thread hooking device cannot complete thread hooking, so that the height position of the thread hooking device needs to be lowered. Referring to fig. 6 and 7, the utility model discloses an embroidery machine colludes traditional thread binding putting 2, including installing in the colluding line ware 21 of aircraft nose casing, still install riser 22 on the aircraft nose casing, when needs collude the line, riser 22 drive collude line ware 21 by initial height descend to colluding the line position, collude the line and accomplish the back, riser 22 drive colludes line ware 21 and rises to initial height. Therefore, the problem that the conventional thread hooking device cannot complete thread hooking after the height of the shuttle box body is reduced is solved.
In this embodiment, the lifter 22 is a cylinder installed vertically with the piston rod facing downward. Moreover, for convenience of installation, the air cylinder is installed on the side surface of the machine head shell. The piston ejector rod is connected with a connecting plate 23 through a top plate at the end part, the thread hooking device 21 comprises a thread hooking bottom plate, the thread hooking bottom plate is provided with a side bending plate 211, and the side bending plate is connected with the connecting plate through screws.
Of course, it will be understood by those skilled in the art that a linear motor or the like could be used in place of the air cylinder.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
