Conventional antibacterial products such as silver ions and copper ions contain heavy metals and cannot meet high-quality requirements, especially the antibacterial and environmental protection performance requirements of textiles in special industries such as national defense, military police, and medical treatment. Products with skin cooling function can better meet the needs of consumers.

[0003] Therefore, the company included the "research and development of cool and antibacterial nylon 6 pre-oriented yarn" in the 2020 new product research and development plan. After years of annual expenses, it has developed a method that can produce cool and antibacterial nylon 6 pre-oriented yarn. Utility Model Content

[0004] The utility model aims to provide a production line for cool and antibacterial nylon 6 pre-oriented yarns, which can complete the preparation of cool and antibacterial nylon 6 pre-oriented yarns.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a production line of cool and antibacterial nylon 6 pre-oriented yarn, comprising a mixer, a screw extruder, a spinning assembly, a twister, a pre-network device and a winder arranged in sequence, characterized in that it also includes a thread former located between the twister and the spinning assembly, the twister comprising a base, a friction disk and three vertical rotating shafts, the base is provided with a through hole through which the silk strips pass, the silk strips cooperate with the friction disks on the three vertical rotating shafts, the vertical rotating shafts are equipped with a driving motor, the friction disks are provided with a plurality of spaced apart arrangement along the length direction of the vertical rotating shafts, the three vertical rotating shafts are a first vertical rotating shaft, a second vertical rotating shaft and a third vertical rotating shaft arranged in a triangular shape on the base, the first vertical rotating shaft and the second vertical rotating shaft slide with the base respectively The invention is configured to adjust the twisting force on the silk strip by slidingly adjusting the positions of the first vertical rotating shaft and the second vertical rotating shaft; the thread former comprises a flat circular base, a vertical central shaft head rotatably connected to the center of the circular base and provided with a silk hole, a central gear connected to the vertical central shaft head, an intermediate gear meshing with the central gear, an inner gear ring meshing with the intermediate gear and a rotating sleeve rotatably mounted on the circular base, the rotating shaft of the intermediate gear is rotatably connected to the circular base, the inner gear ring is fixed on the inner circumferential surface of the rotating sleeve, there are at least three intermediate gears, and the three intermediate gears surround the central gear, the rotating sleeve is connected to a knife rod, and the free end of the knife rod is provided with a sharp blade located in the rotating sleeve for cutting grooves on the surface of the silk passing through the silk hole. The force required for twisting the cool antibacterial nylon stretch yarn developed by the present application is different from that of general materials, and needs to be improved compared with the prior art. Therefore, in the twister part of the device proposed by the present application, the yarn and the through hole are located between three vertical rotating shafts, and the friction disks on the three vertical rotating shafts rotate in the same direction to achieve twisting of the yarn. The twisting force can be adjusted by sliding the positions of the first vertical rotating shaft and the second vertical rotating shaft, and the twisting force can be adjusted to improve the preparation efficiency and success rate of the yarn. Before twisting, the central vertical rotating shaft rotates while the yarn moves forward, driving the rotating sleeve to rotate, so that the sharp blade scratches the surface of the yarn, thereby forming a thread groove on the surface of the yarn. The formation of the thread groove makes it more reliable to tighten when twisting, and is conducive to oil retention. When the yarn moves vertically, the surface is threaded, which can reduce the influence of the yarn sagging caused by gravity. The yarn sagging will result in the inability to form a groove on the surface of the yarn.

[0006] Preferably, there are at least two knife bars, which are evenly distributed along the circumference of the vertical center shaft head, extend radially along the vertical center shaft head, and the sharp edges of all knife bars are located on the same plane perpendicular to the axis of the vertical center shaft head, and the sharp edges of all knife bars are at an equal distance from the axis of the vertical center shaft head. This can avoid the wire from avoiding when the sharp edge cuts the wire, so that the depth of the formed thread groove is consistent, and multiple threads can be formed.

[0007] Preferably, the knife bar extends in a horizontal direction, the rotating sleeve is provided with a connecting sliding hole, the connecting sliding hole penetrates the rotating sleeve in the radial direction of the rotating sleeve, the knife bar is inserted into the inner end of the connecting sliding hole, the outer end of the connecting sliding hole is threadedly connected with a positioning top screw, and the knife bar is in contact with the top screw. It can conveniently and reliably meet the cutting depth protection requirements of the packaging sharp blade.

[0008] Preferably, a thickening block aligned with the connecting sliding hole is provided on the inner surface of the rotating sleeve, and the connecting sliding hole passes through the thickening block, so that reliable connection to the knife rod can be achieved when the rotating sleeve is thin-walled.

[0009] Preferably, the rotating sleeve is provided with a plurality of connecting through holes distributed along the circumference of the rotating sleeve, and a plurality of connecting bolts are passed through the connecting through holes one by one and then threadedly connected to the outer circumference of the inner gear ring to fix the outer gear ring and the rotating sleeve together. The inner gear ring is formed by a plurality of sections butted together, which is convenient for installation and removal of the inner gear ring.

[0010] Preferably, the rotating sleeve is provided with a bearing sleeved on the circular base, and the upper end of the rotating sleeve is provided with an inner flange, which is supported on the upper surface of the circular base through a supporting ball. The rotating sleeve can rotate in the groove on the circular base, and can prevent the rotating sleeve from falling off the circular base due to the downward pulling force when the sharp blade cuts the wire.

[0011] Preferably, a driven gear is provided at the upper end of the vertical center shaft head, the driven gear is meshed with a driving gear, the driving gear is connected to the power output shaft of the rotating motor, and the rotating motor is fixed on the upper surface of the circular base. A technical solution for driving the vertical center shaft head to rotate is provided. The components are compact and convenient.

[0012] Preferably, the circular base is further provided with a suspension arm. When in use, the thread former is installed by fixing the suspension arm at a set position.

[0013] Preferably, the first vertical rotating shaft, the second vertical rotating shaft and the third vertical rotating shaft are respectively provided with transmission gears, and the three transmission gears are matched on the inner side of the same belt loop. The three vertical rotating shafts are synchronously driven by meshing the same belt loop with the three rotating gears. At the same time, because the three vertical rotating shafts are all located on the inner side of the belt loop, the three vertical rotating shafts can rotate in the same direction, realizing reliable twisting of the silk strips at the through hole, and the twisting efficiency is high.

[0014] Preferably, a slider is provided on both the first vertical rotation axis and the second vertical rotation axis, a slide groove matching the slider is provided on the base, a sliding locking device is provided between the slider and the slide groove, the straight line where the slide groove is located passes through the through hole of the base, the through hole is arranged coplanar with the axis of the third vertical rotation axis, and the slide grooves corresponding to the first vertical rotation axis and the second vertical rotation axis are arranged in a plane symmetrically with respect to the plane where the through hole and the third vertical rotation axis are located. The two symmetrically arranged slide grooves enable the first vertical rotation axis and the second vertical rotation axis to be adjusted in equal amounts relative to the third vertical rotation axis, ensuring that the friction disks on the first vertical rotation axis and the second vertical rotation axis always have similar friction effects, ensuring twisting efficiency, and the setting of the sliding locking device enables the first vertical rotation axis and the second vertical rotation axis to be positioned relative to the base after adjustment, ensuring adjustment efficiency.

[0015] Preferably, the transmission gear on the third vertical rotating shaft is a multi-stage speed-regulating gear, and the transmission gears corresponding to the first vertical rotating shaft and the second vertical rotating shaft are respectively arranged in equal size.

The transmission gear on the third vertical rotating shaft includes three transmission stages. The first stage gear has a smaller diameter than the second stage gear because it is required to form a reduction transmission. Therefore, the area of ​​the belt loop wrapped around the transmission gear where the third transmission shaft is located is reduced. At the same time, the first vertical rotating shaft and the second vertical rotating shaft move in a direction away from the third vertical rotating shaft, and the distance between the friction disks on the first vertical rotating shaft and the second vertical rotating shaft and the silk strip increases. The twisting force of the friction disks on the first vertical rotating shaft and the second vertical rotating shaft on the silk strip is also reduced, and the speed is also slowed down, thereby meeting the demand for decelerating and twisting the silk strip. Conversely, when the twisting force needs to be increased, the belt loop cooperates with the third stage gear, and the area of ​​the belt loop and the third stage gear that cooperates increases. The first vertical rotating shaft and the second vertical rotating shaft move toward the side where the third vertical rotating shaft is located, and the friction disks on the first vertical rotating shaft and the second vertical rotating shaft provide greater pressure on the silk strip, thereby increasing the twisting force.

[0016] Preferably, a connecting frame is provided on the base, and the connecting frame includes a vertical vertical rod and a horizontal rod. The vertical rod is rotatably connected to the base, and the horizontal rod is provided with an open limit groove that can be coaxial with the through hole, and the vertical rod is provided with a locking component that can be tightly pressed against the base. After the locking component locks the vertical rod, the vertical rod cannot rotate, ensuring the limiting effect of the open limit groove on the wire strip. When the vertical rotating shaft or the friction disk needs to be replaced and repaired, the locking component can be unlocked, and the vertical rod can be rotated to separate the open limit groove from the wire strip, thereby improving the maintenance efficiency.

[0017] Preferably, an oil storage chamber is provided in the vertical rotating shaft, and a plurality of sliding holes distributed along the circumference of the friction disc are provided on the peripheral surface of the friction disc, and the sliding holes are connected to the oil storage chamber through oil passages, and a plug is provided in the sliding hole. The centrifugal force generated when the vertical rotating shaft rotates drives the plug to close the sliding hole, and when the wire strip presses on the plug, the plug is driven to move into the sliding hole and open. During rotation, the plug remains closed under the centrifugal action, and when the plug presses the wire strip to twist the wire strip, the plug is pressed to open, and the oil in the oil storage chamber flows out to oil the wire strip. This realizes oiling while twisting.

[0018] Preferably, when the plug covers the slide hole, the outer end surface of the plug and the outer peripheral surface of the friction disk are located on the same plane, so that the friction during twisting can be kept more sufficient.

[0019] Preferably, the generatrix of the outer peripheral surface of the friction disc is an arc line that bulges outward radially along the friction disc, which can reduce the resistance in the moving direction of the wire strip.

[0020] Preferably, the oil outlet cavity is provided with a filling hole and a balancing hole, the filling hole is sealed and connected with a hole cover, and the balancing hole is provided with a one-way valve opening toward the outside of the oil storage cavity, so that after the oil in the oil storage cavity flows out, the internal air pressure is kept balanced with the atmospheric pressure, so that the plug can be reliably opened when twisting the wire.

[0021] Preferably, the oil storage chamber is cylindrical and extends in the direction of rotation. The oil storage chamber is coaxial with the vertical rotation shaft. A spiral blade extending in the vertical direction is provided on the wall of the oil storage chamber. When the vertical rotation shaft rotates to twist the wire strip, the direction of the force generated by the spiral blade is to drive the oil in the oil storage chamber to rise. When the amount of oil is small, the oil can flow out from the sliding holes of each friction wheel.

[0022] Preferably, the opening direction of the sliding hole faces downward, and the weight of the plug drives the plug to move toward the outside of the sliding hole so that the plug seals the sliding hole, thereby improving the reliability of the plug when sealing.

[0023] The beneficial effects of the utility model are: it can complete the preparation of cool and antibacterial nylon 6 pre-oriented yarn; the twisting force is adjustable and easy to adjust, especially with a three-level convenient adjustment method; it can simultaneously complete oiling and form a thread groove and then twist, which can make it less likely to spread after twisting, and has a good adhesion effect when oiling.

Slide blocks 14 are arranged on the first vertical rotation shaft 4 and the second vertical rotation shaft 5, and a slide groove 15 matching the slide blocks 14 is arranged on the base 1. Figure 3 As shown, the cross-sectional shape of the slide 15 is dovetail-shaped, and the width of the upper and lower ends of the slider 14 is greater than the width of the middle part of the slider 14, so that the slider 14 will not fall in the slide 15. A bearing is arranged in the slider 14, and the lower ends of the first vertical rotation axis 4 and the second vertical rotation axis 5 are respectively connected to the corresponding bearings and then pass through the bottom of the slider 14 to connect the transmission gear. A sliding locking device is arranged between the slider 14 and the slide 15, and the sliding locking device includes a butterfly bolt 16 threadedly connected to the slider 14, and the lower end of the butterfly bolt 16 can be pressed against the slide 15 to achieve locking after passing through the slider 14. The straight line where the slide 15 is located passes through the through hole 3 of the base 1, and the through hole 3 is arranged coplanar with the axis of the third vertical rotation axis 6. The slides 15 corresponding to the first vertical rotation axis 4 and the second vertical rotation axis 5 are arranged in a plane symmetrical with respect to the plane where the through hole 3 and the third vertical rotation axis 6 are located. The driving motor 24 directly drives the third vertical rotating shaft 6 to rotate coaxially on the lower side of the base 1. When the third vertical rotating shaft 6 rotates, it transmits the power to the first vertical rotating shaft 4 and the second vertical rotating shaft 5 through the belt ring 13 and the transmission gear to drive the first vertical rotating shaft 4 and the second vertical rotating shaft 5 to rotate together.

[0034] The transmission gear on the third vertical rotating shaft 6 is a multi-stage speed regulating gear 9. The first transmission gear 7 and the second transmission gear 8 corresponding to the first vertical rotating shaft 4 and the second vertical rotating shaft 5 are set to be equal in size.
