Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to a tensioning device of a yarn twisting machine. Background Art

[0002] In the knitting and weaving of automotive textile interior processing, a yarn twisting machine is needed. However, the yarn often breaks when it is transported to the twisting machine, which undoubtedly affects the weaving efficiency and the quality of the fabric, and largely determines the company's benefits. The breakage rate depends largely on the tension of the yarn feeding device on the yarn.

[0003] The Chinese patent with publication number CN206512380U discloses a yarn feeding device for a knitting machine. This yarn feeding device adjusts the tension by adjusting the height of the second roller and the third roller. The structure of this yarn feeding device is relatively complex. At the same time, after the tension adjustment is completed, the second roller and the third roller are locked, so that the tension cannot be adaptively changed according to the production process. In addition, the yarn generates static electricity due to friction with the roller during transportation, which is easy to adhere to dust and intertwine and entangle.

[0004] Therefore, we propose a tensioning device for a yarn twisting machine to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a tensioning device for a yarn twisting machine, which solves the problem that the tension of the existing yarn cannot change adaptively according to the production process during transportation. In addition, the yarn generates static electricity due to friction with the roller during transportation, which makes it easy for dust to adhere and for interweaving and entanglement to occur.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a tensioning device of a yarn twisting machine, comprising a frame, an active guide roller mechanism is installed on the frame for yarn transportation, and a second rotating roller is rotatably installed above the frame for yarn guiding and transportation;

[0007] A tension adjustment mechanism is provided between the active guide roller mechanism and the second rotating roller for adjusting the tension of the yarn;

[0008] The tension adjustment mechanism comprises a fixed frame fixed on the frame, a cylinder is fixed on the top of the fixed frame, an adjustment frame is installed on the bottom end of the cylinder, and a third roller is rotatably installed on the bottom end of the adjustment frame;

[0009] The frame is equipped with a static elimination mechanism for eliminating static electricity of the yarn and guiding and conveying the yarn;

[0010] The static elimination mechanism comprises a wire transmission trough body fixed on a frame, and a plurality of static elimination rollers arranged in two rows and parallel to each other are rotatably mounted on the wire transmission trough body;

[0011] A water-washing static-eliminating mechanism is arranged on the frame and above the static-eliminating mechanism for eliminating static electricity during yarn washing.

[0012] Preferably, the active guide roller mechanism comprises a motor fixed on a frame, and a first rotating roller is mounted on an output end of the motor.

[0013] Preferably, a bracket is fixed on the frame, and two ends of the second roller are rotatably mounted on the bracket via bearings.

[0014] Preferably, both ends of the line transmission trough are open, and one end of the static elimination roller is in contact with the ground through a wire.

[0015] Preferably, the water washing static electricity elimination mechanism includes a box fixed on the top of the line transmission trough and connected to the interior of the line transmission trough, a water pump is fixed on the line transmission trough, the water inlet of the water pump is connected to an external water source through a pipeline, the water outlet is connected to a plurality of water pipes extending to the inside of the box through a water outlet pipe, and an atomizing nozzle is installed at the end of the water pipe.

[0016] Preferably, a fan is installed above the frame and on one side of the wire conveying trough body to air-dry the yarn output from the static electricity elimination roller.

[0017] Beneficial Effects

[0018] The utility model provides a tensioning device for a yarn twisting machine. Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. A tensioning device for a yarn twisting machine. After being unwound by an unwinding mechanism, the yarn first passes through a first roller, then passes under a third roller, then passes over a second roller, and finally passes between two static-eliminating rollers to be guided and transported to the yarn twisting machine. During the transporting process, the tensioning force of the yarn at the bottom of the third roller can be adjusted by starting the cylinder to drive the adjustment frame to move downward and drive the third roller to move downward, thereby ensuring the stability of the yarn tension and ensuring production efficiency and product quality.

[0020] 2. In the tensioning device of the yarn twisting machine, two static elimination rollers are used to guide and convey the yarn, and one end of the static elimination roller is grounded through a wire, so that the static electricity on the surface of the yarn passing therethrough can be eliminated, thereby removing the static electricity generated by friction on the surface during transportation, and by starting the water pump, external water is pumped into the water outlet pipe and the water guide pipe, and atomized and sprayed onto the yarn surface through the atomizing nozzle, thereby eliminating the static electricity on the yarn surface through water washing, achieving a further static electricity elimination effect, thereby solving the existing problems of static electricity generated by friction with the rotating roller during transportation, easy adhesion of dust, and easy interweaving and entanglement.
