The guide wire is connected with the sequins in series, and the opening and closing mechanism 31 of the plectrum device 3 periodically opens the tail end channel of the sequins catheter 4, so that the sequins are sent out one by one at fixed time intervals and are presented at fixed distance intervals on the continuously downward moving guide wire; finally twisting and plying the guide wire stringed with the sequins and the prepared napping yarn to prepare the sequin napping yarn; the production process is coherent, the automation degree is high, the large-scale inlaying of the sequins on the napping yarn is facilitated, and the production efficiency is improved.
Step S1 includes: step S11, dyeing, namely dyeing the 1.5D 38 acrylic loose fibers serving as raw materials; step S12, mixing wool, namely spreading the fibers after the disperse dyeing, adding water, opening and mixing into a mixed material with uniform color; step S13, carding, namely feeding the mixed material into an A186 carding machine to prepare wool tops of 20 g/m; step S14, drawing, namely feeding the wool tops into an FA306A drawing frame to be subjected to three-pass drawing, and homogenizing evenness and color; and step S15, drafting, namely drafting the drawn wool tops by a roving machine to prepare the uniform roving with the quantitative gram weight of 0.8 g/m, which is beneficial to the continuous production of the subsequent process.
In step S2, 0.8 g/m of roving is used as a decorative yarn, two 20/70 nylon covered spandex yarns are used as core yarns, 100D high-elastic chinlon is used as a pressing yarn and is sent into a VFF32B twisting machine, the twist of a hollow spindle is 740 twists/m, the untwisting twist is 300 twists/m, the overfeeding multiple is 1.8 times, and the tension of the core yarns is 1.1 times.
The number of the paillette napped yarn is 1/12.2 NM.
The sequin napping yarn comprises the following components in parts by weight: 49% of acrylon, 33% of chinlon, 15.5% of terylene and 2.5% of spandex.
In step S5, the method for controlling the distance between the sequins includes: if the spacing between the sequins on the sequin napping yarns is to be increased, the controller controls the rotating speed of the servo motor 32 to be reduced; if the spacing between the sequins on the sequin napping yarns is reduced, the controller controls the rotating speed of the servo motor 32 to be increased; the position precision of the servo motor 32 is accurate, and the rotating speed of the turntable 312 is changed by controlling the rotating speed of the servo motor 32 so as to change the relative moving speed between the material baffle 315 and the horizontal plate 313, namely the time period of the overlapping and non-overlapping states of the through hole 314 and the material baffle groove 316, thereby changing the time period that the paillettes in the paillette guide tube 4 pass through the through hole 314 one by one: the faster the rotation speed of the servo motor 32 is, the shorter the time period that the paillettes in the paillette guide tube 4 pass through the through holes 314 one by one is, and the shorter the distance interval of the paillettes on the guide line is; the slower the speed of the servo motor 32 is, the longer the time period during which the paillettes in the paillette guide tube 4 pass through the through holes 314 one by one is, and the longer the distance interval between the paillettes on the guide wire is.
The production equipment and the production process of the sequin napping yarn have the working principles that: the guide wire is connected with the sequins in series, the opening and closing mechanism 31 of the plectrum device 3 periodically opens the tail end channel of the sequins conduit 4, so that the sequins are sent out one by one at fixed time intervals and are presented at fixed distance intervals on the continuously downward moving guide wire, and finally the guide wire which is connected with the sequins in series is twisted and plied with the napping yarn to prepare the sequins napping yarn; the production process is coherent, the automation degree is high, the large-scale inlaying of the sequins on the napping yarn is facilitated, and the production efficiency is improved.
The turntable 312 is driven by the servo motor 32 to rotate, one end of the connecting rod 317 is driven by the turntable 312 to rotate along the turntable 312, the other end of the connecting rod 317 continuously pushes and pulls the material blocking plate 315 to slide along the horizontal plate 313, when the material blocking groove 316 on the material blocking plate 315 is overlapped with the through hole 314 on the horizontal plate 313, a guide line can simultaneously pass through the material blocking groove 316 and the through hole 314, but a sequin is blocked by the material blocking groove 316; when the material blocking groove 316 on the material blocking plate 315 is not overlapped with the through hole 314 on the horizontal plate 313, the sequins naturally fall by gravity and move downwards along with the guide wire; with the rotary disc 312 being driven by the servo motor 32 to make a rotary motion, the connecting rod 317 pushes and pulls the material blocking plate 315 in a fixed time period, so that the material blocking groove 316 and the through hole 314 are in an overlapped or non-overlapped state in the fixed time period, and the sequins in the sequin guide tube 4 pass through the through hole 314 one by one in the fixed time period, thereby realizing the phenomenon that the sequins on the guide wire are presented at intervals of a fixed distance; the rotating speed of the turntable 312 is changed by controlling the rotating speed of the servo motor 32, so that the relative moving speed between the material baffle 315 and the horizontal plate 313, namely the time period of the overlapped and non-overlapped state of the through hole 314 and the material baffle groove 316 is changed, and the time period of the sequins in the sequin guide tube 4 passing through the through hole 314 one by one is changed; the faster the rotation speed of the servo motor 32 is, the shorter the time period that the paillettes in the paillette guide tube 4 pass through the through holes 314 one by one is, and the shorter the distance interval of the paillettes on the guide line is; the slower the speed of the servo motor 32 is, the longer the time period during which the paillettes in the paillette guide tube 4 pass through the through holes 314 one by one is, and the longer the distance interval between the paillettes on the guide wire is.
In conclusion, the invention connects the guide wire with the sequins in series, and periodically opens the end channel of the sequins conduit 4 by the opening and closing mechanism 31 of the plectrum device 3, so that the sequins are sent out one by one at fixed time intervals, and are presented at fixed distance intervals on the continuously downward moving guide wire, and finally the guide wire connected with the sequins in series is twisted and plied with the napped yarn to prepare the sequin napped yarn; the automation degree is high, large-scale embedding of the sequins on the napped yarn is facilitated, and the production efficiency is improved; the periodic interval of the sequins on the sequin napping yarns can be changed by changing the rotating speed of the servo motor 32, and the flexibility of adjusting the spacing of the sequins is improved. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
