Description

Yarn breakage alarm device for pultrusion process

Technical Field

The utility model relates to a combined material pultrusion and weaving technical field say in detail to a yarn broken string alarm device for pultrusion technology.

Background

As is well known, a large amount of various fibers are often used in the pultrusion process or the textile process, but in the using process, the purpose that a new cylinder of fibers can be replaced and connected in time after each cylinder of fibers is used is difficult to achieve due to the overlarge number of the fibers, thereby leading the fiber quantity to often fail to meet the process requirements, the fiber arrangement changes, when the number of operators is small, the workload is large, the timely access is difficult to ensure, the product quality can not be ensured, when the number of operators is increased, the labor cost is higher, therefore, how to ensure the stability of the quantity and the arrangement of the yarns on the basis of effectively controlling the cost becomes a difficult problem to be solved urgently, in addition, the conventional yarn alarming device can effectively monitor the abnormal condition of yarn running-out or normal breakage, however, the yarn breakage at the die opening often occurs in the pultrusion process, which is a problem that the conventional alarm device cannot effectively monitor.

Disclosure of Invention

In order to overcome prior art's not enough, the utility model provides a pultrusion is yarn alarm device that breaks off the line for technology to whether the yarn roller normally rotates as the decision criteria, can effectively monitor various types of yarn and run and the fracture.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a pultrusion is yarn alarm device that breaks for technology, be equipped with the pultrusion mould, a serial communication port, the die orifice department of pultrusion is equipped with the pultrusion machine, the yarn roller is installed through the pivot in the pultrusion machine top, install adjustable coding wheel on the pultrusion machine of yarn roller inboard, adjustable coding wheel presses on the yarn roller through the flexure strip, adjustable coding wheel comprises encoder and tachometer, the inside aluminum alloy material that adopts of tachometer, the outer rubber coating of tachometer adopts wear-resisting polyurethane material, the encoder links to each other with the signal input part of singlechip controller through signal transmission line, the signal output termination audible-visual annunciator of singlechip controller.

The beneficial effects of the utility model are that, simple structure, the cost of manufacture is lower, and sensitivity is higher, and the warning degree of accuracy is higher to whether the yarn roller normally rotates for judging the standard, can effectively monitor various types of yarn and run and the fracture.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1, a yarn roller, 2, an adjustable coding wheel, 3, an audible and visual alarm, 4, a single chip microcomputer controller and 5, a pultrusion die are arranged.

Detailed Description

In the figure, the utility model is provided with a pultrusion die 5, a pultrusion machine is arranged at the die orifice of the pultrusion die 5, a yarn roller 1 is arranged above the pultrusion machine through a rotating shaft, the shape of the yarn roller 1 is cylindrical, the inner diameter of the yarn roller 1 is fixed on the pultrusion machine, yarns are started from the outer side of the yarn roller 1, an adjustable coding wheel 2 is arranged on the pultrusion machine at the inner side of the yarn roller 1, the adjustable coding wheel 2 is pressed on the yarn roller 1 through an elastic sheet, the adjustable coding wheel 2 consists of an encoder and a rotating speed wheel, the rotating speed wheel is internally made of aluminum alloy material, the outer layer of the rotating speed wheel is coated with wear-resistant polyurethane material, the adjustable coding wheel 2 leans against the yarn roller 1 under the extrusion of the elastic sheet and can synchronously roll along with the rotation of the yarn roller 1, and the encoder can collect data and measure the actual rotating speed of the rotating speed wheel, the encoder is connected with the signal input end of a singlechip controller 4, the signal output end of the singlechip controller 4 is connected with the audible and visual alarm 3. The single chip microcomputer controller 4 is a control system of the whole device, a lowest rotating speed is set on the single chip microcomputer controller 4, when the actual rotating speed measured by the adjustable encoding wheel 2 is lower than a set value, the single chip microcomputer controller 4 outputs an alarm signal, and when the rotating speed signal returns to be normal, the alarm is automatically cancelled, and the automatic monitoring state is restored. The audible and visual alarm 3 is normally on in a normal state, has no prompt tone, and after receiving the alarm signal output by the singlechip controller 4, the green lamp is turned off, the red lamp is normally on, and the alarm prompt tone is continuously sent out.
