Description

Rotational speed control device of WINGS winder pulley

The technical field is as follows:

the utility model relates to a polyester filament yarn fiber production field specifically says a rotational speed control device of WINGS winder pulley.

Background art:

in the production of polyester filament yarn, an automatic winding machine is a key device for winding spinning cake forming. At present, the common equipment is a Bamaging WINGS winding machine, 10 tows on the equipment pass through 2 godets and then pass through 10 pulleys arranged in tandem respectively, and are wound into spinning cakes after going to a shifting fork and a forming sheet. The process controls a shifting fork and a forming piece by adjusting forming angle parameters, and controls tension by adjusting the rotating speed of a godet (the tension refers to the tension between the godet and a pulley), thereby finally achieving the purpose of controlling the forming of the spinning cake. The forming angle parameter controls 10 cakes simultaneously, not for a single cake. Since 10 tows are all on the same godet, the tension is also adjusted for individual cakes. The pulley only plays a role in changing the direction of the tows, and is not driven by a motor, so that the rotating speed cannot be controlled. The surface friction of the pulleys in contact with the filament bundles at the beginning of the use of the new device is almost the same as the friction of the pulleys with the base, so that the tension between the pulleys and the godet is almost the same for 10 filament bundles in the new device. But the difference between the pulleys of the same winder begins to develop during long use, resulting in a large difference in tension of 10 wires. Meanwhile, due to the fact that the time for replacing the new pulley is different due to faults, the difference of 10 strand tensions on the same winder is increased due to the influence of the pulley, and the 10 strand cakes are formed differently. While current means of adjustment cannot be directed to individual cakes.

The utility model has the following contents:

the utility model aims to solve the technical problem that a control pulley rotational speed is provided, reduce tension difference between the silk bundle and improve the fashioned rotational speed control device of WINGS winder pulley of spinning cake.

The technical solution of the utility model is that, a rotational speed control device of WINGS winder pulley is provided, including fixed magnetic support, be equipped with cavity regulation seat on the fixed magnetic support, the spring has been held in the cavity regulation seat, and there is the leather head subassembly spring top butt, contradicts through leather head subassembly and pulley and realizes the adjustment to the pulley rotational speed, and leather head subassembly lower extreme holding is adjusted in the seat and is adjusted the seat height-adjustable in vertical side with cavity in the cavity.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: the length of the leather head extending out of the hollow adjusting seat is adjusted, so that the effect of controlling the contact force between the leather head and the side face of the pulley is achieved, the friction force between the leather head and the pulley is controlled, and the purposes of controlling the rotating speed of the pulley and the tension of tows are finally achieved.

Preferably, the leather head assembly comprises a leather head and a metal fixing block fixed below the leather head.

Preferably, the upper surface of the scalp is planar.

Further, the seat is adjusted to cavity is the hollow column structure, and its side has the card hole with leather head subassembly complex, and the card hole sets up along vertical direction interval, and is corresponding, is equipped with on the leather head subassembly with card hole complex fixture block.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is another schematic side view of the present invention.

Fig. 3 is a schematic view of the present invention cooperating with the pulley.

Fig. 4 is a schematic view of a pulley structure of a winder in the prior art.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1-4, a rotation speed control device for a pulley of a WINGS winder comprises a fixed magnetic base 1, a hollow adjusting base 2 is arranged on the fixed magnetic base 1, the connection mode is bonding fixation, the hollow adjusting base 2 is an aluminum alloy pipe with a closed lower end, a spring 3 is accommodated in the hollow adjusting base 2, the bottom of the spring 3 abuts against the bottom surface of the hollow adjusting base 2, a leather head component is abutted against the upper side of the spring 3, the pulley rotation speed is adjusted by abutting against a pulley 6 through the leather head component, and the lower end of the leather head component is accommodated in the hollow adjusting base and can be adjusted in height in the vertical direction with the hollow adjusting base.

Specifically, the leather head assembly comprises a leather head 4 and a stainless steel pipe 5 sleeved below the leather head, a groove is formed in the bottom surface of the leather head assembly in a sealed or concave mode, a spring is conveniently accommodated, the leather head 4 can be made of snooker leather and is formed by pressing pigskin or cowhide, and the leather head 4 is inserted into the stainless steel pipe and is fixedly bonded. The leather head 4 upper surface is the arc surface for the plane, in order to realize adjusting from top to bottom, can adopt buckle structure, cavity regulation seat is the hollow columnar structure promptly, its side have with leather head subassembly complex card hole 21, card hole 21 sets up along vertical direction interval, it is corresponding, be equipped with on the leather head subassembly 4 with card hole complex fixture block 51, the fixture block 51 welds on the nonrust steel pipe 5 of leather head subassembly, the fixture block structure is the square form, it is corresponding, the card hole is for corresponding the structure. For convenient regulation, the clamping hole is also communicated with a vertically arranged chute 22 on one side, the chute 22 is a through groove, and the clamping block can slide in the through groove.

The larger the contact force between the elastic leather head and the side surface of the pulley is, the larger the friction force between the elastic leather head and the side surface of the pulley is, and the slower the rotation speed of the pulley is; whereas the smaller the force between them, the smaller the friction force and the faster the pulley rotation speed. The speed of the pulley can control the tension of the tows. After 10 pulleys are additionally provided with the device, the rotating speed of the pulleys is controlled by adjusting leather heads, and finally the adjusting position is determined by measuring the tension through a tension meter. Therefore, the tension difference of 10 silk bundles can be controlled to a reasonable range, and the forming difference of the spinning cake can be reduced. When in use, the fixed magnetic seat 1 is adsorbed on the pulley pull rod 7 to play a role in fixing. One for each pulley 6. Then adjust the length that the leather head stretches out the cavity through the buckle and adjust the seat, play the dynamics size effect of control leather head and pulley side contact to control the frictional force between leather head and the pulley, finally reach the purpose of control pulley rotational speed, silk bundle tension. The operation steps are as follows: the device is mounted to a designated location. The second step is that: the tension is measured while the leather head is adjusted.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
