Abstract

The invention provides an automatic cloth spreading tightness adjusting device of a cloth spreading machine and realizes that tightness of cloth spread by the cloth spreading machine can be automatically adjusted and accuracy of cloth cutting can be increased. The automatic cloth spreading tightness adjusting device mainly comprises a tightness detecting device. The tightness detecting device detects cloth spreading tightness to transmit to a controller, the controller is connected with a servo motor connected with a cloth feed mechanism, and the control device receives cloth spreading tightness signals transmitted by the tightness detecting device and controls the servo motor to increase or decrease cloth feed speed. The automatic cloth tightness adjusting device of the cloth spreading machine has the advantages that cloth spreading tightness on the cloth spreading machine can be automatically stably adjusted, and accordingly, accuracy of cloth cutting is increased, and both labor and cloth are saved.

Description

Tentering machine is regulated the take-up of granny rag automatically

Technical field

The present invention relates to a kind of adjusting elasticity device, particularly relate to a kind of tentering machine automatic tightness regulating device.

Background technology

At present, the degree of tightness control that existing tentering machine spreads cloth all is to control by operator's manual regulation, can not effectively regulate the elasticity that tentering machine spreads cloth, the regularity at wayward good cloth two ends.

Summary of the invention

In order to solve the problem of tentering machine energy automatic tightness regulating when spreading cloth, improve the accuracy rate of fabric dividing, the invention provides the take-up that a kind of tentering machine is regulated granny rag automatically; One tightness detector, the degree of tightness amount of detection granny rag is delivered to a control setup, control setup is connected with servomotor, servomotor is connected with cloth feeding mechanism, and the granny rag that control setup reception tightness detector is sent here loosens, tighten signal, and work feed speed is accelerated or slowed down to the control servomotor.

Described tightness detector is to fix a photoelectric detector with a plate on the cutting knife device of tentering machine, and photoelectric detector detects the position that granny rag moves, and records the degree of tightness amount of granny rag.

Described control setup is PLC or micro controller system.

Described servomotor is controlled the motion of a cloth feeding mechanism, and the control elasticity sent of cloth and machine walking amount are always at a kind of state of dynamical equilibrium.

Advantage of the present invention is, can automatic steady ground regulates the granny rag elasticity on the tentering machine, thereby improved the accuracy rate of fabric dividing, both saved manpower, saved again cloth.

Description of drawings

Fig. 1 is the installation position right elevation of tentering machine automatic tightness regulating device of the present invention;

Fig. 2 is the installation position left view of tentering machine automatic tightness regulating device of the present invention;

Fig. 3 is that tentering machine automatic tightness regulating device of the present invention is installed in the block diagram on the tentering machine cutting knife device;

Fig. 4 is the controlling party block diagram of tentering machine automatic tightness regulating device of the present invention.

The specific embodiment

See also accompanying drawing 1-shown in Figure 3, the invention will be further described.One tightness detector 1, detect the degree of tightness amount of granny rag, deliver to a control setup 2, control setup 2 is connected with servomotor 3, servomotor 3 is connected with cloth feeding mechanism 7, control setup 2 receives the granny rag amount of the loosening, tighten signal that tightness detector 1 is sent here, and control servomotor 3 makes cloth feeding mechanism 7 accelerate or slow down work feed speed.

Described tightness detector 1 is to fix a photoelectric detector 5 with a plate 6 on the cutting knife device 4 of tentering machine, and photoelectric detector 5 detects the position that granny rag moves, and records the degree of tightness amount of granny rag; When granny rag because of too loose, drop on cutting knife device 4 below, photoelectric detector does not detect granny rag, illustrate granny rag too the pine; When granny rag because of too tight, exceed the normal position and be detected, illustrate that granny rag is too tight.

Described control setup is PLC or micro controller system.
