Description

Technical Field

[0001] This utility model relates to the technical field of winding devices, specifically a multi-constant tension winding device for PP hollow yarn. Background Technology

[0002] PP hollow fiber, also known as polypropylene hollow fiber, is a chemical fiber with a special microstructure.

[0003] During the yarn winding process, the mass of the package on the unwinding reel decreases, resulting in a significant reduction in its moment of inertia. This change disrupts the mechanical balance that maintains constant unwinding tension, leading to insufficient resistance torque at the unwinding end and causing the yarn tension to decrease. Ultimately, yarn with unstable tension can result in quality problems such as loose winding, uneven density, or uneven end faces. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A multi-constant tension winding device for PP hollow yarn includes a winding mechanism, a monitoring mechanism, and a tension constant mechanism. The winding mechanism includes a bracket and a device body rotatably mounted on the top of the bracket. The monitoring mechanism includes two bobbins fixedly connected to the top of the bracket, a pressure sensor embedded in the bottom surface of the bobbins, a pay-off roller rotatably connected between the two bobbins, and a display screen fixedly connected to the bobbin near the front side of the bracket. The pressure sensor is attached to the bottom of the pay-off roller and electrically connected to the display screen. The tension constant mechanism includes two supports fixedly connected to the tops of the two bobbins, a sandbox fixedly connected to the top of the supports, a speed regulating valve installed on the output end of the sandbox, four telescopic rods fixedly connected to the bottom of the supports, a sand receiving box connected between the four telescopic rods, and a rubber sheet fixedly connected to the bottom of the sand receiving box. The rubber sheet is interference-fitted to the top of the pay-off roller.

[0007] By adopting the above technical solution, two pressure sensors detect the weight on the pay-off roller in real time and feed the data back to the display screen. The display screen adjusts the opening and flow rate of the speed control valve in real time according to the internal algorithm. When the weight is detected to be decreasing, the speed control valve opens and the fine sand in the sand box is gradually added to the sand receiving box through the vertical pipe. The increased weight is transmitted through the rubber sheet as frictional resistance to the pay-off roller, thereby maintaining its initial rotation speed and achieving constant control of the winding tension.

[0008] In a preferred embodiment, the present invention can be further configured such that both cylindrical supports are located on one side of the main body of the device, and the two cylindrical supports are arranged opposite to each other.

[0009] In a preferred embodiment, the present invention can be further configured such that: the sandbox is composed of a rectangular box and a vertical pipe, the body of the vertical pipe extends through the top of the support frame, the top end of the vertical pipe is fixedly connected to the bottom of the sandbox, and the speed regulating valve is installed on the vertical pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that four telescopic rods are arranged in a matrix, and the speed regulating valve is located between the four telescopic rods.

[0011] In a preferred embodiment, the present invention can be further configured such that the sand receiving box is trapezoidal and its inner wall is polished.

[0012] In a preferred embodiment, the present invention can be further configured such that: both the front and rear sides of the rubber sheet are fixedly connected with retaining edges, and the retaining edges are in contact with the outer wall of the wire feeding roller.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, two pressure sensors detect the weight on the pay-off roller in real time and feed the data back to the display screen. The display screen adjusts the opening and flow rate of the speed control valve in real time according to the internal algorithm. When the weight is detected to be decreasing, the speed control valve opens and the fine sand in the sand box is gradually added to the sand receiving box through the vertical pipe. The increased weight is transmitted through the rubber sheet as frictional resistance to the pay-off roller, thereby maintaining its initial rotation speed and achieving constant control of the winding tension.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a multi-constant tension winding device for PP hollow yarn.

[0028] Example 1:

[0029] Combination Figure 1-5 As shown, the present invention provides a multi-constant tension winding device for PP hollow yarn, including a winding mechanism 100, a monitoring mechanism 200 and a tension constant mechanism 300. The winding mechanism 100 includes a bracket 110 and a device body 120 rotatably mounted on the top of the bracket 110.

[0030] The monitoring mechanism 200 includes two cylindrical frames 210 fixedly connected to the top of the bracket 110, a pressure sensor 220 embedded in the bottom surface of the cylindrical frame 210, a wire feeding roller 230 rotatably connected between the two cylindrical frames 210, and a display screen 240 fixedly connected to the cylindrical frame 210 near the front side of the bracket 110. The pressure sensor 220 is attached to the bottom of the wire feeding roller 230 and electrically connected to the display screen 240.

[0031] The tension constant mechanism 300 includes two supports 310 fixed to the top of two drum frames 210 respectively, a sand box 320 fixed to the top of the supports 310, a speed regulating valve 330 installed on the output end of the sand box 320, four telescopic rods 340 fixed to the bottom of the supports 310, a sand receiving box 350 connected between the four telescopic rods 340, and a rubber sheet 360 fixed to the bottom of the sand receiving box 350. The rubber sheet 360 is interference-fitted to the top of the pay-off drum 230.

[0032] Furthermore, both roller frames 210 are located on one side of the main body 120 of the device, and the two roller frames 210 are arranged opposite each other. The layout design of the roller frames 210 provides conditions for the stable placement of the wire feeding rollers 230.

[0033] Furthermore, the sand box 320 is composed of a rectangular box and a vertical tube. The vertical tube extends through the top of the support frame 310, and the top of the vertical tube is fixedly connected to the bottom of the sand box 320. The speed regulating valve 330 is installed on the vertical tube. The structural design of the sand box 320 allows the fine sand inside the sand box 320 to flow smoothly into the sand receiving box 350.

[0034] Furthermore, the four telescopic rods 340 are arranged in a matrix, and the speed regulating valve 330 is located between the four telescopic rods 340. The layout design of the telescopic rods 340 ensures that the sand box 350 can be raised and lowered stably.

[0035] Example 2:

[0036] Combination Figure 1 , 2 and Figure 5 As shown, based on Embodiment 1, the sand receiving box 350 is set in a trapezoidal shape and the inner wall is polished. The structural design of the sand receiving box 350 ensures that all the fine sand inside can be taken out.

[0037] Example 3:

[0038] Combination Figure 1-2 As shown, in the above embodiment, the rubber sheet 360 is fixedly connected to both the front and rear sides with a retaining edge 400. The retaining edge 400 is in contact with the outer wall of the wire feeding roller 230. The retaining edge 400 can limit the rubber sheet 360 so that it can stably press down on the wire feeding roller 230.

[0039] The working principle and usage process of this utility model are as follows: When this device is put into actual use, two pressure sensors 220 detect the weight transmitted from the pay-off roller 230 in real time. The detected value is reflected to the display screen 240. Then, the algorithm inside the display screen 240 controls the opening state and flow rate of the speed regulating valve 330 in real time. When the detected value shows a downward trend, the speed regulating valve 330 is opened. Then, the fine sand in the sand box 320 is added little by little into the sand receiving box 350 through the vertical pipe. Correspondingly, the weight of the sand receiving box 350 is applied to the rubber sheet 360. The rubber sheet 360 presses down and rubs against the pay-off roller 230 to maintain the initial rotation speed of the pay-off roller 230, thereby maintaining a constant winding tension.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
