Description

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

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 universality.

Background

Fiber manufacturing and fiber products exist in the forms of yarns, threads, ropes and belts, and a winding machine is adopted to carry out finished product forming. The method is divided into two categories: parallel winding and cross winding. The yarn is wound on a disc-type wire coil in a parallel winding mode, and the angle between a winding angle and a spool is 90 degrees. The diameter of the wire coil is different, the weight of the single-tube wound yarn is different, and the diameter of the common wire coil is 300-400 mm. The cross winding is to wind the yarn on a cylindrical paper tube, and a certain angle is formed between the winding direction and the paper tube shaft, and the specific angle depends on the product. The diameter and the stroke of the paper tube adopted also depend on the requirements of yarn products, and the change is also large. Generally, a winding machine is used as a component part of a fiber and fiber product manufacturing production line, multiple spindles run simultaneously, long-time stable operation is required, and the spindles have high consistency, high applicable objects (suitable for different surface physical characteristics of yarns, such as roughness, thickness and hardness) and various forming modes (such as stroke, winding angle, winding density, winding tension range and paper tubes or wire coils). At present, two types of winding machines (parallel and cross winding machines) in the market mostly adopt a single-motor speed-reducing gear and worm and gear technology, and some winding machines even have no constant tension control means, so that the winding machines are usually a machine type aiming at one product and influence the soft production organization of a production line. Although the one-time investment cost of the winding machine is low, the maintenance work is heavy, the maintenance manpower and material investment is high, more importantly, the winding machine is linked with a production line, the winding quality is unstable, the output of the production line and the quality of finished products are influenced, and the maximum utilization of the production line is limited. For example, patent CN201010227978.3, a constant tension system for a winding machine that automatically adjusts the tension of a wire rope mechanically and electronically, comprising: the device comprises a winding head fixing plate, an integrated circuit board, a constant tension mechanism, a winding density adjusting mechanism, a butterfly sheet horizontal retaining mechanism and a lifting arm pressure adjusting mechanism; the integrated circuit board is arranged on the winding head fixing plate, the constant tension mechanism is fixed above the winding head fixing plate and is connected with the arm lifting pressure adjusting mechanism, the butterfly sheet horizontal retaining mechanism is connected with the winding head fixing plate and is fixed on the arm lifting pressure adjusting mechanism, and the winding density adjusting mechanisms are distributed on two sides of the winding head fixing plate; the constant tension mechanism comprises mechanical adjustment and electronic tracking adjustment, wherein the mechanical adjustment and the electronic tracking adjustment are fixed on a winding head fixing plate. This patent relates to a winding apparatus for the light textile industry, and in particular to a winding machine that can employ a mechanically and electronically adjustable constant tension system that automatically tracks cords.

Furthermore, patent CN96236085.6 proposes a new magnetic transmission pair and a new tension control method for controlling the tension of plastic flat wire, in which the driving disk is an optical aluminum disk 6 driven by a motor 7, the driven disk is a magnetic disk 5 mounted on a winding shaft 19, and the control board 4 pulled by the flat wire is used to change the tension of winding. The structure of the panel 1, the fastening and quantitative moving mode of the motor 7 and the structure and the fixing mode of the magnet 29 of the patent have obvious effects on improving the winding quality of the spindle and reducing the cost.

The winding machine on the market at present has the following technical problems:

0. the machine type universality problem, parallel winding and cross winding are of two types, the stroke is fixed, the winding angle is fixed, and the two types cannot be used universally.

1) high-abrasion failure of a winding arm consisting of a worm gear and a slide block sliding needle under high-speed operation.

2) The high-speed reciprocating steering action has the phenomena of lag and inaccuracy.

2. The compatibility problem of the reel connection structure is as follows:

1) the compatibility of the main shaft design is not enough, and the wire coil and the paper tube are not compatible.

2) The winding angle cannot be adjusted at will. If angular adjustment is required, the gears must be replaced.

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

3. Constant tension realizing mode

The initial adjustment of the winding tension is determined by the performance and the compression of the spring, the elastic coefficient is changed along with the service life, and the spring needs to be replaced and cannot be free of maintenance. And the determined spring properties, i.e. the determined tension range, determine the limited applicability.

4. Adjustment mode of winding density

The winding density is mechanically adjusted (belt position is adjusted), and uncertain drift occurs along with the elongation and the slip of the belt.

5. Winding head arm-raising mode

When the paper tube is used for realizing a cross winding mode, the winding head needs to generate corresponding displacement along with the increase of the diameter of the bobbin, the original machine type adopts a mechanical sliding rod, and due to the reasons of lubrication or deformation and the like, the lever lifting force is changed, namely the force acting on the bobbin is not constant.

6. Paper tube tensioning mode

The paper tube is sleeved on the main shaft, the top of the paper tube is tensioned through the spring by means of the manual operation arm, the spring can change along with time performance, and needs to be frequently replaced and manually operated.
