Abstract
A safety protection device for drawing frame transmission comprises a creeling motor connected with a main machine, wherein a shaft sleeve of the motor is connected with an output shaft of the motor through a key pin, and is sleeved by a gear; the shaft end is pressed tightly through a bolt by an end cover; a pressing plate is arranged at the front end of the output shaft; a disc spring is mounted between the pressing plate and the gear; the pressing plate is fixed with an adjusting bolt by a round nut; and two friction sheets are respectively arranged at the front part and the rear part of the gear. The safety protection device has the benefits that the routine is broken, the friction transmission manner is boldly adopted in an automatic creeling transmission, and the safety performance of the automatic creeling action is greatly improved. The safety protection device has the direct effects that the action is gentle, the damage to parts and cans is reduced, and the safety of operators is increased.
Description
Affiliated technical field
The utility model relates to a kind of Cotton Drawing Frame tool of product continuous reeling, particularly a kind of safety guard of drawing frame transmission.
Background technology
In drawing frame transmission safeguard protection field various ways is arranged; machine driving causes then air switch tripping operation of electromotor overload unusually; machine driving unusually causes the torque increase and causes shear pin breakage, machine driving to cause that unusually overload causes flat belt to fall band, also has photoelectricity automatic stop etc.These several modes can play the safeguard protection effect; but drawing frame is to move under high-speed condition, can not stop after breaking down at once, and certain potential safety hazard is arranged; in automatic creeling process, sliver can blocks and causes the infringement of parts or personnel's injury.
Summary of the invention
The purpose of this utility model is to overcome the existing deficiency of prior art, and a kind of transmission safety guard of drawing frame is provided, and it can prevent from blocking the infringement that causes parts or personnel's injury because of sliver can in the automatic creeling process effectively.
Technical solution of the present utility model is:
A kind of safety guard of drawing frame transmission, comprise the creeling motor, the creeling motor is connected with main frame, the axle sleeve of motor is connected with motor output shaft by key pin, geared sleeve is on axle sleeve, and by screw in compression, it is characterized in that: the front end at output shaft is provided with pressing plate to axle head with end cap, the dish spring is housed between pressing plate and the gear, and pressing plate is fixed with round nut and adjustment screw; Friction plate is equipped with respectively in the front and back of described gear.
The beneficial effects of the utility model are: 1, break the normal procedure, automatically courageously adopting frictional drive in the creeling transmission, the security of automatic creeling action is significantly improved, its direct effect is that action is soft, damage to parts reduces, and the destructiveness minimizing to the bar cylinder has also increased operating personnel's security; 2, adjustment screw has been installed on the pressing plate, frictional force can be regulated, can according to practical working situation, driving force be adjusted like this, also can compensate machine the work long hours fatigue of rear spring and the wearing and tearing of friction plate, the transmission safety device is succinctly reliable, takes up room little, is convenient to installation and removal, easy to maintenance, the cost of drive disk assembly is lower.
Description of drawings
Fig. 1 is the cutaway view of the utility model structure.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is described in further detail:
Referring to Fig. 1, the creeling reducing motor 1 of the automatic creeling transmission device of drawing frame is along the horizontal cross setting, and the axle sleeve 2 of this motor is connected with motor output shaft 4 by key pin, and gear 3 is enclosed within on the axle sleeve 2, axle head compresses by screw 7 with end cap 8, prevents axle sleeve 2 axial floats; The front end of described output shaft 4 is provided with pressing plate 5, between pressing plate 5 and the gear 3 dish spring 10 is housed, and pressing plate 5 is fixing with adjustment screw 6 with round nut 9, and adjustment screw 6 can be regulated frictional force; Friction plate 11,12 is equipped with respectively in the front and back of described gear 3.
Operation principle: pass through gear transmission mode, gear is applied certain axial compressive force, correspondingly produce frictional force, when actual load during less than frictional force, gear and motor rotate together, when actual load during greater than frictional force, skid between gear and the axle sleeve, gear stops the rotation, and the creeling action also can stop automatically.Dynamic transmission from frictional force, regulate frictional force, can guarantee the motion of mechanism, in when cylinder card, mechanism kinematic stops, protection parts and sliver can not damage, and have guaranteed operating personnel's safety yet.
Although above shown detailed embodiment of the present utility model, those skilled in the art is under prerequisite of the present utility model, can carry out the part modifications and changes; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not limitation of the utility model, and has the safety guard of a kind of drawing frame transmission of above-mentioned technical characterictic, all falls into this patent protection domain.
