Abstract
A V-shaped shear knife device comprises a rodless cylinder, a V-shaped shear knife and a rodless cylinder seat, and is characterized in that the cutting edge of the V-shaped shear knife is in a V shape, the V-shaped shear knife is arranged on the rodless cylinder seat through screws, the rodless cylinder is arranged on a doffer frame, and the air sources are connected with the rodless cylinder. The V-shaped shear knife device solves the problems that the yarn breaking rate of a doffing machine does not reach 100%, and production efficiency and automation are affected, and is suitable for being used for yarn breaking of the doffing machine.
Description
Technical field
The utility model relates to field of textile machinery, specifically the V-type shear knife device on a kind of fine spining machine.
Background technology
Shear knife plays the effect of cutting off yarn in doffer work, so that the carrying out of tube drawing, intubate operation.At present, known shear knife form has form to have presser type, mechanical type, but both are for broken yarn line time, because yarn self intensity is large and soft, the rate of cutting short does not reach 100%, causes doffer automatically to carry out next step operation, affects the carrying out of production efficiency and automation.
Utility model content
The utility model is in order to solve doffer in yarn cutting lineman does, and broken yarn rate does not reach 100%, affects the problem of the carrying out of production efficiency and automation, and a kind of V-type shear knife device is provided.
The technical scheme that the utility model adopts is, a kind of V-type shear knife device, comprise Rodless cylinder, V-type shear knife, Rodless cylinder seat, its special character is: the blade of V-type shear knife is " V " type, V-type shear knife is arranged on Rodless cylinder seat by screw, Rodless cylinder is arranged on and doffs on vehicle frame, and source of the gas is connected with Rodless cylinder.
During work, source of the gas is opened, and Rodless cylinder promotes Rodless cylinder seat and moves rapidly left under the effect of air pressure, and the blade of V-type shear knife cuts off through yarn and by yarn, makes yarn separated with spindle, reaches the object of cutting continuous strand.
Technique effect of the present utility model is, adopts above-mentioned technical scheme, can realize that a control is easy, operating efficiency is high, realizes the V-type shear knife device of yarn cut-out rate 100%.
Accompanying drawing explanation
Fig. 1 is topology view of the present utility model, and the accompanying drawing that makes an abstract.
Fig. 2 is use state diagram of the present utility model.
In the drawings, doff vehicle frame, 7 screws, 8 right sources of the gas, 9 left sources of the gas of 1 Rodless cylinder, 2 " V " type shear knife, 3 Rodless cylinder seats, 4 yarns, 5 spindles, 6.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in the figure, the blade of V-type shear knife 2 is " V " type, and V-type shear knife is arranged on Rodless cylinder seat 3 by screw 7, and Rodless cylinder 1 is arranged on and doffs on vehicle frame, and source of the gas 8 is connected with Rodless cylinder 1.
During work, source of the gas 8 is opened, and Rodless cylinder 1 promotes Rodless cylinder seat 3 and moves rapidly left under the effect of air pressure, and the blade of V-type shear knife 2 cuts off through yarn 4 and by yarn 4, makes yarn 4 separated with spindle 5, reaches the object of cutting continuous strand.
