Description

Lap pressure hook lifting limiting photoelectric switch

Technical field

The utility model relates to textile industry Electromechanical Control technical field, specifically a kind of lap pressure hook lifting limiting photoelectric switch for blowing lapper.

Background technology

At present, known blowing equipment as model be in A076 lapper, when lap meter cover with volume after lap pressure hook along with motor forward start rising, complete cotton thick stick release movement; Lap pressure hook rises to certain position rear motor reversion lap pressure hook and drops to again original position.As shown in Figure 2, lap pressure hook 1 lower end is cast with tooth bar, the gear driven lap pressure hook 1 of lifting motor 2 circular shafts moves up and down, mechanical contact 6 is fixed on lap pressure hook 1, and move up and down with the lifting of lap pressure hook 1, lower limit travel switch 3 and upper limit travel switch 4 are arranged on respectively on travel switch bracket 5.When lap doff, lifting motor 2 obtains electric forward rotation, by rack drives lap pressure hook 1, does ascending motion.When mechanical contact 6 touches upper limit travel switch 4, upper limit travel switch 4 sends signal enabling lifting motor 2 and starts reversion, lap pressure hook 1 declines, when lap pressure hook 1 touches lower limit travel switch 3, lower limit travel switch 3 sends 2 stalls of signal notice lifting motor, lap pressure hook 1 declines by inertia, and all lick-up has moved.

Because the tooth bar of lap pressure hook 1 is large tooth pitch engaged transmission, parts coordinate excesssive gap inaccurate and that mechanical wear causes usually to make the hypertelorism of mechanical contact and travel switch or excessively near, the shake-up scope that surpasses travel switch: hypertelorism can cause travel switch to can't detect signal, can not at extreme position, stop rapidly, cause parts to damage and burn-down of electric motor; Hypotelorism can make mechanical contact that travel switch is broken, and produces mechanical bad car, the serious security incident hidden danger such as fire that even cause.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of lap pressure hook lifting limiting photoelectric switch, the lap pressure hook lifting that can effectively avoid mechanical wear, excesssive gap to cause is malfunctioning, stops the generation of equipment, element damage accident.

For achieving the above object, the gear driven lap pressure hook of lifting motor of the present utility model moves up and down, travel switch bracket is fixed in frame, diffuse reflector is equipped with in described lap pressure hook upper end, upper limit optoelectronic switch, lower limit optoelectronic switch are contained in respectively the upper/lower terminal of travel switch bracket, and described upper limit optoelectronic switch, lower limit optoelectronic switch and diffuse reflector form lap pressure hook position probing.

The utility model compared with prior art, optoelectronic switch maintains static, diffuse reflector substitutes machinery and rams, by the larger feature of diffuse reflection type optoelectronic switch reflector space, not only contact-free but also reliable in action, can effectively overcoming mechanical wear, gap, to become the lap pressure hook lifting causing greatly malfunctioning, avoids equipment, element damage accident, effectively stops the potential safety hazards such as fire.

Accompanying drawing explanation

Fig. 1 is structural representation sketch of the present utility model.

Fig. 2 is the structural representation sketch of prior art.

Embodiment

As shown in Figure 1, the gear driven lap pressure hook 1 of lifting motor 2 moves up and down, travel switch bracket 5 is fixed in frame, diffuse reflector 7 is equipped with in described lap pressure hook 1 upper end, upper limit optoelectronic switch 9, lower limit optoelectronic switch 8 are contained in respectively the upper/lower terminal of travel switch bracket 5, and described upper limit optoelectronic switch 9, lower limit optoelectronic switch 8 form lap pressure hook position probing with diffuse reflector 7.

When blowing doff, lifting motor 2 obtains electric forward rotation, by rack drives lap pressure hook 1, do vertical motion, in the process that lap pressure hook 1 rises, the diffuse reflector 7 of mounted thereto is first by lower limit optoelectronic switch 8, but because of uphill process, limiting photoelectric switch 8 is inoperative at present, when lap pressure hook 1 rises to upper limit optoelectronic switch 9, send rising stop signal and start lifting motor 2 reversions; Lap pressure hook 1 declines, and in decline process, during through lower limit optoelectronic switch 8, lower limit optoelectronic switch 8 sends signal and makes lifting motor 2 stalls, and lap pressure hook 1 declines by inertia, and all lick-ups have moved.Because diffuse reflection type optoelectronic switch reflector space is larger, not only contact-free but also reliable in action, can effectively overcome mechanical wear, that gap becomes the lap pressure hook lifting causing is greatly malfunctioning, avoids equipment, element damage accident, effectively stops the potential safety hazards such as fire.
