[0024] Embodiment

[0025] As Figures 1 to 3 shown, the utility model discloses a polyester low elastic filament production line's feeding mechanism, including the chassis 1 and the polyester low elastic filament roll, the bottom of chassis 1 is equipped with several universal pulleys 12, universal pulley 12 is a kind of pulley that can rotate freely in multiple directions, usually by a central bearing and the pulley around the bearing is formed.It is designed so that the pulley can rotate at any angle and direction, with high flexibility, widely used in the occasion that load direction needs to be changed or complex mechanical movement is needed.It also includes: fixedly installed on the upper surface of chassis 1 U-shaped support 101, the bottom of U-shaped support 101 is fixedly connected with fixed base bar 2;Slidingly arranged in U-shaped support 101 multiple sequentially corresponding sliding rods 3, sliding rod 3 is all fixedly connected with multiple support insertion rods 232 that are linearly arranged and support polyester low elastic filament roll, the core hollow design of polyester low elastic filament roll, the action is convenient for support insertion rod 232 insertion placement.Fixed base bar 2 and the both ends of sliding rod 3 are all fixedly connected with U-shaped sliding block 231, the U-shaped sliding block 231 of sliding rod 3 end is slidably connected with U-shaped support 101;Driving mechanism, setting in the chassis 1 so that multiple sliding rods 3 are supported by fixed base bar 2 and synchronous expansion and contraction.

[0026] Further, the driving mechanism includes a pair of fixed frames 11 fixedly connected in the chassis 1, the middle part of fixed frame 11 is fixedly connected with support frame 111, the middle part of support frame 111 is movably connected with screw rod 4, the top end of screw rod 4 is movably connected with rotating top seat 42, the end away from screw rod 4 of rotating top seat 42 is fixedly connected with U-shaped support 101, one of sliding rods 3 is screw-connected with screw rod 4 away from chassis 1, and the other multiple sliding rods 3 are movably sleeved with screw rod 4.

[0027] The driving mechanism further comprises a rotating rod 13 rotatably connected in the chassis 1, and the two ends of the rotating rod 13 are rotatably connected with the inner wall of the chassis 1. One end of the rotating rod 13 is fixedly sleeved with a sleeve 15, the outer wall of the sleeve 15 is fixedly connected with a plurality of rotating handles 16 arranged in a circumferential array, the middle part of the rotating rod 13 is fixedly sleeved with a first inclined gear 14, and the bottom end of the screw rod 4 is movably penetrated through the support frame 111 and fixedly connected with a second inclined gear 41. The first inclined gear 14 and the second inclined gear 41 are conical gears, which are a kind of gear commonly used to transmit rotary motion and torque. The angle between the gear shaft and the driving shaft of the conical gear is usually 90 degrees, but it can also be designed to be other angles. The tooth surface of the conical gear is usually conical, hence the name. The tooth surface is usually at an angle to the axis, so that this gear is particularly suitable for transmitting power between two non-collinear shafts. The second inclined gear 41 is in meshing connection with the first inclined gear 14, and the middle part of the fixed base rod 2 and the sliding rod 3 is provided with a plurality of pairs of U-shaped rotating seats 233. One pair of U-shaped rotating seats 233 is rotatably connected with a first inclined rotating rod 234, and the other pair of U-shaped rotating seats 233 is rotatably connected with a second inclined rotating rod 235.

Just turn the rotating handle 16 to drive the sleeve 15 to rotate, the sleeve 15 drives the rotating rod 13 and the first inclined gear 14 on the rotating rod 13 to rotate, because the first inclined gear 14 is meshed with the second inclined gear 41 above, so the first inclined gear 14 drives the second inclined gear 41 to rotate, the second inclined gear 41 drives the spiral rod 4 to rotate through the support frame 111, and the top end of the spiral rod 4 rotates through the support of the rotating top seat 42, because the spiral rod 4 is screw connected with the sliding rod 3 away from the base frame 1, so the spiral rod 4 drives the sliding rod 3 to move upwards. Then through the first inclined rotating rod 234 and the second inclined rotating rod 235 of the fixed bottom rod 2 and the middle part of the plurality of sliding rods 3, because the rotation and stretching of the first inclined rotating rod 234 and the second inclined rotating rod 235 are based on the same geometric relationship, all the first inclined rotating rod 234 and the second inclined rotating rod 235 will stretch at the same proportion and direction at the same time, ensuring the consistency of the overall stretching height. Thus the distance between the fixed bottom rod 2 and the plurality of sliding rods 3 is synchronized to become larger or smaller, and finally the up and down distance of the U-shaped rotating seat 233 on the sliding rod 3 is changed according to the size of the polyester low elastic yarn roll.
