Description

Wire take-up device and method

Technical Field

Background

All the processes for pretreating and dyeing the knitted fabrics with spandex comprise the following general processes: scutching, presetting, hemming, preprocessing or dyeing, taking out of a vat, dehydrating, slitting, drying or setting.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

An embodiment of the present invention, as shown in fig. 1 to 3, includes:

the device comprises a vertical plate 1, wherein an active motor 21 is arranged on one side of the vertical plate, and an active motor shaft 22 of the active motor penetrates through the vertical plate and is positioned on the other side of the vertical plate;

a wire pressing wheel 3 is arranged on the motor shaft; the fabric collecting roller is arranged on the driving motor shaft, and the fabric collecting roller is arranged on the driving motor shaft. As shown in the figure, the wire pressing wheel keeps the pressure of the wire pressing wheel on the shaft of the driving motor through the pressing wheel depending on the spring. As shown in the figure, the wire pressing wheel is arranged on the vertical plate through a bracket, and a guide rod is sleeved on the guide rod. A handle is arranged on one side of the support, and the wire pressing wheel can be lifted from the shaft of the driving motor, so that yarns can be placed between the wire pressing wheel and the shaft of the driving motor.

A take-up motor 4 is further mounted on one side of the vertical plate, and a take-up motor shaft 41 of the take-up motor penetrates through the vertical plate and is located on the other side of the vertical plate; a friction disc 42 is fixed on the shaft of the wire take-up motor, so that the rotation speed of the friction disc 42 is the same as that of the wire take-up motor; a take-up pulley 5 is rotatably arranged on the take-up motor shaft corresponding to the friction disc, and the take-up pulley is arranged on the take-up motor shaft through a bearing and does not rotate with the motor shaft; the take-up pulley comprises a contact part 51 arranged corresponding to the friction disc and a take-up frame 52 arranged around the contact part; in order to increase the friction force, a rubber layer or the like may be provided on the surface of the friction disk.

A pressure regulating device is sleeved on one side of the take-up motor shaft far away from the take-up motor; the pressure regulating device comprises a pressure regulating spring 61 which is sleeved on the take-up motor shaft and a pressure regulating cover 62 which is screwed at the front end of the take-up motor shaft, wherein the pressure regulating spring is positioned between the pressure regulating cover and the contact part of the take-up pulley.

The pressure regulating cover is matched with the pressure regulating spring to regulate the friction force of the contact part of the friction disc and the take-up pulley, so that a smaller friction force exists between the contact part of the friction disc and the take-up pulley; therefore, the rotation of the take-up motor does not influence the take-up speed of the driving motor, and the rotation of the take-up wheel is driven only by the friction force between the contact part and the friction disc, so that when the take-up speed of the take-up motor is greater than the rotating speed of the driving motor (the rotating speed of the cloth collecting roller), the contact part between the friction disc and the take-up wheel slips without taking up.

The speed measuring device is used for monitoring the rotating speed of the cloth collecting roller; the speed measuring device can be a speed measuring encoder which is coaxial with the cloth collecting roller, and can also be used for detecting by using a contact roller type speed detecting method, namely, the rotating roller is used for contacting with the fabric, so that the advancing speed of the fabric is calculated according to the rotating speed and the circumference of the rotating roller.

And the control device controls the rotating speed of the driving motor to be matched with the rotating speed of the cloth collecting roller according to the monitoring result of the speed measuring device. The control device can adopt a PLC or a singlechip and the like, and mainly calculates the rotating speed of the driving motor according to the rotating speed or linear speed monitored by the speed measuring device so that the take-up speed of the driving motor is the same as the advancing speed of the fabric on the fabric take-up roll.

Furthermore, a handle 7 is arranged on the take-up pulley, so that manual operation of the take-up pulley can be conveniently carried out.

As a further improvement of the invention, a driving wheel with the diameter equivalent to that of the cloth collecting roller is arranged on the shaft of the driving motor, so that the rotating speed of the driving motor can be the same as that measured by a speed measuring device, and the rotating speed is not required to be calculated into linear speed conversion.

The wire take-up method of the device comprises the following steps:

monitoring the rotating speed of the cloth collecting roller by using a speed measuring device in real time;

controlling the rotating speed of the driving motor according to the monitored rotating speed of the cloth collecting roller, so that the linear speed of a motor shaft or a driving wheel of the driving motor is the same as that of the cloth collecting roller;
