The utility model discloses a be applied to syringe needle device of tufting machine, refer to fig. 1 and 2, this tufting machine syringe needle device includes syringe needle body 100 and shell fragment 200. A wire passing cavity 160 is formed in the needle body 100, and one end of the wire passing cavity 160 is communicated with the wire inlet 140 and the other end is communicated with the wire outlet 150. The elastic sheet 200 is arranged in the thread passing cavity 160, one end of the elastic sheet 200 is fixedly connected with the needle body 100, the other end of the elastic sheet and the inner wall of the needle body 100 jointly define a thread passing hole 300 with adjustable aperture size, and the thread passing hole 300 is communicated with the thread passing cavity 160. The thread 400 enters the thread passing chamber 160 from the thread inlet 140 and passes through the thread hole 300 to exit from the thread outlet 150.
If the knitting yarn 400 is thick or the knitting yarn 400 has a knot, the elastic sheet 200 will be forced to spring open towards the side far away from the needle body 100 when the knitting yarn 400 passes through the yarn passing hole 300, so as to enlarge the aperture of the yarn passing hole 300 and enable the knitting yarn 400 to pass through smoothly. The needle head device can smoothly pass through the knitting yarns 400 with different thicknesses, avoids yarn breakage, reduces the shutdown maintenance frequency of the tufting machine, and further can effectively improve the operating efficiency of the tufting machine.
Specifically, referring to fig. 1 to 3, the needle body 100 includes a needle body 110, one end of the needle body 110 is connected to the needle fixing portion 130, and the other end is connected to the needle tip 120, and the needle body 110, the needle fixing portion 130, and the needle tip 120 are integrally formed. The needle fixing part 130 serves to fixedly mount the entire needle unit to the front end position of the tufting machine head.
In the direction in which the thread 400 passes, it is defined that the end into which the thread 400 passes is the rear end of the needle device and the end out of which the thread 400 exits is the front end of the needle device.
The wire inlet 140 is disposed at one end of the needle body 110 (i.e., the rear end of the needle body 110), the wire outlet 150 is disposed at one end of the needle tip 120 (i.e., the front end of the needle tip 120), and the needle body 110 and the needle tip 120 form an open wire passing cavity 160.
The open type wire passing chamber 160 should be understood that, referring to fig. 3, the circumferential walls of the needle body 110 and the needle tip 120 are open-loop circumferential walls, one side (defined as the upper side) of the needle body 110 and the needle tip 120 is a closed structure, the other side (positioned as the lower side) of the needle body 110 and the needle tip 120 is an open structure, and the circumferential walls of the needle body 110 and the needle tip 120 enclose the wire passing chamber 160 with one side open.
One end of the elastic sheet 200 is fixedly connected with the rear end of the needle body 110, and the other end and the inner wall of the needle tip 120 jointly define a wire passing hole 300. The elastic sheet 200 simultaneously plays a certain role in blocking the open side of the thread passing cavity 160, so as to prevent the weaving thread 400 from drooping and exposing from the inside of the thread passing cavity 160.
The open thread passing cavity 160 facilitates installation of the elastic sheet 200, and on the other hand, if the weaving thread breaks or knots occur in the thread passing cavity 160, the elastic sheet 200 can be detached for maintenance, so that the maintenance convenience is improved.
The rear end of syringe needle main part 110 is equipped with first screw hole 111, and the one end of shell fragment 200 is equipped with second screw hole 210, wears to establish screw 500 between first screw hole 111 and the second screw hole 210 to realize fixed connection with the one end of shell fragment 200 and syringe needle main part 110.
The second screw hole 210 is preferably a non-closed screw hole, and if the elastic piece 200 needs to be replaced, the screw 500 is loosened without being completely removed, and the elastic piece 200 can be withdrawn or inserted, thereby improving the convenience of operation.
The other end (front end) of the elastic sheet 200 is provided with an open-loop opening 220, the other end of the elastic sheet 200 is attached to the inner wall of the needle tip 120, and the opening 220 and the inner wall of the needle tip 120 enclose a wire passing hole 300. Therefore, the weaving line 400 can be completely limited in the thread passing hole 300, the weaving 00 is prevented from penetrating out from other positions between the elastic sheet 200 and the inner wall of the needlepoint 120, meanwhile, the weaving line 400 can stably penetrate out, and the weaving line 400 is prevented from swinging back and forth when penetrating out from the thread passing hole 300.
The needle body 110 is provided with a first wire inlet 141 and a second wire inlet 142. The inlet end of the first inlet 141 is disposed at the rear end of the needle body 110 and below the needle fixing portion 130, and the outlet end of the first inlet 141 is disposed at the upper side of the needle body 110. The inlet end of the second inlet 142 is disposed on the upper side of the needle body 110, and the outlet end of the second inlet 142 is disposed on the inner wall of the needle body 110 and is communicated with the wire passing cavity 160. The outlet end of the first inlet 141 and the inlet end of the second inlet 142 are spaced apart from each other to form an observation area 170 therebetween, and the observation area 170 is located outside (specifically, on the upper side) the needle body 110. The weaving thread 400 sequentially passes through the first thread inlet 141, the observation area 170 and the second thread inlet 142, enters the thread passing cavity 160, and then passes through the thread hole 300 and exits from the thread outlet 150. The exposed viewing area 170 facilitates real-time viewing of the condition of the thread 400.
A yarn breakage detecting sensor (not shown) is provided in the observation area 170 to automatically detect a yarn breakage of the weaving yarn 400.
The first thread inlet 141 and the second thread inlet 142 are both inclined along the threading direction of the knitting thread 400, so that the knitting thread 400 can be threaded more smoothly and the phenomenon of pause can be avoided.
Referring to fig. 1, the elastic piece 200 has a certain radian along the length direction of the thread passing cavity 160, specifically, the middle of the elastic piece 200 is curved out towards the outer side of the thread passing cavity 160, and along the penetrating direction of the knitting thread 400 and near the position of the thread passing hole 300, the gap between the elastic piece 200 and the inner wall of the needle tip 120 is gradually reduced until the front end of the elastic piece 200 is combined with the inner wall of the needle tip 120, so that on one hand, the knitting thread 400 is guided, and on the other hand, if the knitting thread 400 is thick or a knot is formed on the knitting thread 400, the knitting thread 400 contacts the elastic piece 200 before penetrating through the thread passing hole 300 and applies a certain acting force to the elastic piece 200, so that the elastic piece 200 can be bounced open towards the side far from the thread passing cavity 160, and further, the aperture of the thread passing hole 300 is enlarged.
The utility model also discloses a tufting machine can be automatic tufting machine or hand-held type tufting machine, is equipped with the disclosed tufting machine syringe needle device of above-mentioned embodiment on this tufting machine's the aircraft nose.
