Description

Brand new maintenance-free high-speed constant tension yarn winding machine with high versatility

technical field

The invention relates to the technical field of winding machines, in particular to a brand-new maintenance-free high-speed constant tension yarn winding machine with high versatility.

Background technique

Fiber manufacturing and fiber products exist in the form of yarn, thread, rope, and belt, all need to use a winder to form the finished product. Divided into two categories: parallel winding and cross winding. The parallel winding type winds the yarn on a spool, and the angle between the winding angle and the spool is 90 degrees. The diameter of the spool is different, and the weight of the single tube of yarn to be wound is also different. The more common spool diameter is 300-400 mm. Cross-winding is to wind the yarn on a cylindrical paper tube with a certain angle between the winding direction and the axis of the paper tube, depending on the product. The diameter and stroke of the paper tube used also depend on the requirements of the yarn product and vary greatly. Usually, the winder is used as a component of the fiber and fiber product manufacturing line to run multiple spindles at the same time, requiring long-term stable operation, high consistency between spindles and high applicable objects (suitable for different surface physical properties of yarn: roughness, thickness, thickness) Degree, hardness) and has a variety of forming methods (stroke, winding angle, winding density, winding tension range, paper tube or spool). At present, there are two types of winders on the market (parallel and cross-winding machines), most of which use single-motor acceleration and deceleration gear and worm gear technology, and some do not even have constant tension control means, often one type of model for one product. Production line flexible production organization. Although this type of winder has a relatively low one-time investment cost, the maintenance work is quite heavy, and the input of maintenance manpower and materials is quite high. More importantly, it is linked with the production line, and the winding quality is unstable, which affects the output of the production line and the finished product. The quality also limits the acquisition of maximum utilization of the production line. For example, patent CN201010227978.3, a winding machine adopts a constant tension system that automatically adjusts the tension of the wire rope mechanically and electronically, including: a winding head fixing plate, an integrated circuit board, a constant tension mechanism, a winding density adjustment mechanism, and a butterfly sheet level Holding mechanism and lifting arm pressure adjustment mechanism; the integrated circuit board is installed on the winding head fixing plate, the constant tension mechanism is fixed above the winding head fixing plate and is connected with the lifting arm pressure adjustment mechanism, and the butterfly sheet horizontal holding mechanism is connected with the winding head The fixed plate is connected and fixed on the lifting arm pressure adjustment mechanism, and the winding density adjustment mechanism is distributed on both sides of the winding head fixed plate; the constant tension mechanism includes mechanical adjustment and electronic tracking adjustment, of which both mechanical adjustment and electronic tracking adjustment are. Fixed on the winding head fixing plate. The patent relates to a winding device for the light textile industry, in particular to a winding machine that can use mechanical adjustment and electronic adjustment to automatically track the constant tension system of the rope.

Furthermore, patent CN96236085.6, this patent proposes a new type of magnetic transmission pair and a new tension control method for plastic flat wire tension control, its active disk is a light aluminum disk 6 driven by motor 7, and its driven disk The magnet disc 5 is mounted on the winding shaft 19, and the control board 4 pulled by the flat wire is used to change the winding tension. The structure of the panel 1 of the patent, the way of tightening and quantitative movement of the motor 7, and the structure and fixing way of the magnet 29 have obvious effects on improving the winding quality of the follicles and reducing the cost.

The current winders on the market have the following technical problems:

0. The problem of model versatility. Parallel winding and cross winding are two types of models. The stroke is fixed and the winding angle is fixed. The two cannot be used in common.

1. High maintenance and repair requirements of the winding arm:

1) The high friction loss of the winding arm composed of the worm gear and the sliding needle of the slider at high speed is ineffective.

2) There will be lag and inaccuracy in the steering action of high-speed reciprocating motion.

2. Compatibility issues of reel connection structure:

1) The spindle design is not compatible enough, and the spool and paper tube applications are not compatible.

2) The winding angle cannot be adjusted at will. If the angle needs to be adjusted, the gear must be replaced.

3) The winding angle is 90 degrees (the angle between the yarn winding direction and the bobbin is 90 degrees), and the yarn is wound on the I-shaped bobbin, which needs to be realized by a parallel winding machine.

3. Realization of constant tension

The initial adjustment of the winding tension is determined by the spring performance and the amount of compression. The elastic coefficient changes with the service life and needs to be replaced, which cannot be maintenance-free. And the determined spring performance, that is, the determined tension range, determines the limited scope of application.

4. Adjustment of winding density

The winding density is mechanically adjusted (adjusting the position of the belt), and an uncertain drift occurs as the belt stretches and slips.

5. Winding head arm lift method

When the paper tube is used to realize the cross-winding method, the winding head needs to have a corresponding displacement with the increase of the diameter of the bobbin. The original model adopts a mechanical sliding rod. Due to lubrication or deformation, the lifting force changes and the effect is The force on the spool is not constant.

6. Tightening method of paper tube

The paper tube is sleeved on the main shaft, and is tensioned by a spring at the top with the help of a manual operation arm. The performance of the spring will change with time, which needs to be replaced frequently, and manual operation is required.
