The opening roller and winding roller on the other side of the I-shaped frame, the hydraulic transmission mechanism that drives the winding roller to rotate, and the electric control box fixed on the frame are composed of the following types of winding machine: shortcoming:

1. Because it is driven by hydraulic pressure, it limits the increase of vehicle speed (only up to 50M/MIN), so it cannot be used well with high-speed finishing equipment with a vehicle speed of 80-100M/MIN, and the oil The structure of the pressure transmission mechanism is complex and the manufacturing cost is high;

2. The hydraulic transmission loses a certain amount of energy due to the return of high-pressure oil, resulting in high energy consumption;

3. This kind of winding machine is fixed, so that it cannot be flexibly configured and used with each production line, which increases the investment in equipment virtually and reduces the use efficiency of the equipment.

The purpose of the invention of the utility model is to provide a winding machine with high speed, simple structure, low energy consumption, and can be flexibly configured and used on various production lines.

The utility model is realized in this way, comprising an I-shaped frame, a cloth guide roller connected to one side of the I-shaped frame, and a tension roller connected to the vertical frame of the I-shaped frame located below the cloth guide roller, connected to The opening roll and winding roll on the horizontal frame on the other side of the I-shaped frame, and the electric control box fixed on the frame, wherein the frame is equipped with a transmission motor, a gearbox, a transmission chain or a transmission The transmission device constituted by the belt, and the winding roller is driven by the transmission device.

In order to achieve stability under high-speed operation and ensure uniform and stable winding tension, the electrical control part is equipped with a device that can respond to changes in winding tension and adjust the speed of the drive motor to control the winding speed to maintain stable winding tension. Open loop control system.

Here, the open-loop control system is mainly composed of a tension sensor used to detect the tension change of the tension roller, and a frequency converter that can adjust the electrical frequency in response to changes in the electrical signal output by the tension sensor. connected to the power input terminals.

In addition, movable wheels are provided under the bottom frame of the I-shaped support, so that the winding machine can be flexibly used in conjunction with corresponding production lines according to actual needs through the movable wheels. The horizontal frame on one side of the fabric guide roller is articulated on the I-shaped frame and supported by oil cylinders. The two oil cylinders supporting the horizontal frame can work when rolling in or unwinding, and the operation is simple.

Compared with the prior art, the utility model adopts chain or belt transmission, which can greatly increase the winding speed of the winding machine and save energy consumption; the utility model adopts an open-loop control system to ensure the winding tension under high winding speed The stability and uniformity of the rolling cloth ensure the packaging quality of the rolled cloth; the movable wheels are set under the frame, which facilitates the movement of the packaging machine, improves the use efficiency of the packaging machine, and saves equipment investment; in addition, the utility model It also has the advantages of simple structure and low manufacturing cost.
