The bobbin winding device 4 further includes a melt adhesive spray tube 44, and the melt adhesive spray tube 44 is located downstream of the winding unit 42.
The working principle and the beneficial effects of the technical scheme are as follows:
the rotary cylinder 4203 is rotatably arranged and can be driven by a motor to rotate around the central axis of the rotary cylinder. A fixed hollow shaft 4208 is coaxially disposed in an inner cavity of the rotary cylinder 4203, the fixed hollow shaft 4208 is fixedly disposed on the holder 4204, and the rotary cylinder 4203 is rotatably disposed on a circumferential surface of the fixed hollow shaft 4208 through a bearing. A warp unreeling rack 4201 is provided at the head end of the fixed hollow core 4208, and a warp unreeling reel 4202 rotatably provided thereon is passed through the head end of the threading passage of the fixed hollow core 4208 in a circumferentially distributed manner and is passed out from the tip end (the tip end is at the winding reel 4209 so as to be welded to the weft on the winding reel 4209) where the warp is exposed and welded to the weft. The rotating drum 4203 is provided with an annular weft bobbin 4205 which rotates with the rotating drum 4203, and the weft thread wound by the weft thread releasing disc 4206 passes through the thread passing hole of the winding disc 4209 and then is guided by the weft thread guiding wheel 4210 to be pushed by the weft thread pushing device 43 to be close to the warp thread (in fig. 3, eight axial warp threads are distributed in the center of the winding disc 4209 in the circumferential direction). The conductive ring 4207 is energized for weft and the power supply is low voltage and high current for contact welding. The weft pushing device 43 pushes the weft to the warp in the axial direction, and the current flows from the section with small resistance, so that the spot welding between the weft and the warp is realized.
The plurality of warp threads have gaps therebetween, so that the charged weft thread cannot always be located at a close point (the weft thread pusher 43 is located at a close point when the weft thread comes into contact with the warp thread, and the weft thread pusher 43 is located at a far point when the distance between the weft thread and the warp thread is the greatest). The weft pushing device 43 is required to push the weft to a near point when the weft is transferred to the warp forward position during the rotation of the rotary cylinder 4203, and the contact between the weft and the warp realizes spot welding; when the weft is far from the warp forward position, the weft pushing device 43 pushes the weft to a far point, and the weft and the warp are separated.
The weft thread pushing device 43 pushes the weft thread to move linearly toward the center of the circle. If adopt the pneumatic cylinder to carry out the propelling movement, the impact force that not only produces is great, leads to the propelling movement distance not enough moreover easily and can't effective spot welding. If adopt cam constructional device to carry out the propelling movement, can't accomplish to promote weft and in time keep away from warp, because ionization, if warp can not be kept away from in the short-term fast to weft, often can lead to weft, warp adhesion, seriously influences the structural strength of wire mesh skeleton.
Therefore, the weft yarn pushing device 43 provided by the invention can achieve the pushing effect of 'slow advancing and fast separating', and the pushing period is consistent with the warp yarn distance. The pushing motor 4302 rotates clockwise (in the direction of fig. 6) to drive the transmission shaft 4303, and the synchronous ball 4306 abuts against the pushing rotating ring 4308 in the bevel edge synchronous groove 4304 to rotate clockwise. During the clockwise rotation of the push rotating ring 4308, since it is in contact fit with the push sliding column 4310 through the first wavy surface 4312 and the second wavy surface 4313, and under the guiding action of the linear sliding guide key 4311, when the wave trough of the first wavy surface 4312 contacts with the wave crest of the second wavy surface 4313 (fig. 7), the push sliding column 4310 is at the highest point, the abutting spring 4314 is in a relaxed state, the weft electrode wheel 4319 is at a far point, and the weft and warp are in a separated state. When the peaks of the first wavy surface 4312 and the second wavy surface 4313 are in contact (fig. 8), the push strut 4310 is at the lowest point, the abutment spring 4314 is in a compressed state, the weft electrode wheel 4319 is at the near point, and the weft and warp are in contact state for spot welding. As shown in fig. 8, when the push ring 4308 continues to rotate, the wave crest of the first wavy surface 4312 instantaneously falls into the wave trough of the second wavy surface 4313, and under the action of the abutting spring 4314, the weft electrode wheel 4319 instantaneously retracts to avoid the adhesion of the weft and warp. When the pushing motor 4302 rotates clockwise unintentionally and rotates counterclockwise erroneously, the synchronization ball 4306 in the bevel synchronization groove 4304 will not abut against the inner wall of the pushing rotation ring 4308, so that the pushing rotation ring 4308 cannot rotate therewith, and the weft electrode wheel 4319 is always in a retracted state.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
