Description
Technical field:
The utility model relates to Circular Knitted Technology field, the cylinder that the pneumatic yarn change mechanism more specifically to a kind of computer knitted circular knitting machine is used.
Background technique:
CN202214565U discloses a kind of Full computer numerical control pneumatic thread adjusting mechanism for double circular knitting machine, as shown in Figure 1, it is by driving cylinder A1 to drive scissors bit A2 action, scissors bit has multiple, cylinder A1 is driven also to be multiple so corresponding, but scissors bit A2 is smaller, and multiple scissors bit A2 is that the mode taking to stack is arranged together, and do not have at present suitable cylinder to be stacked together on the market to drive scissors bit, so we need design one to take up room little, and are applicable to the pneumatic yarn change mechanism of computer knitted circular knitting machine cylinder used.Meanwhile, the piston rod of ordinary casing when driving, employing be the action that a blow puts in place, cause scissors bit A2 action too fast, so easy stretch-broken yarn, haves much room for improvement.
What adopt between piston rod with scissors arm-tie A3 is the mode that Rapid contact is separated, and scissors arm-tie A3 is hauled by extension spring A4, and such scissors arm-tie A3 resets too fast, haves much room for improvement.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides the pneumatic yarn change mechanism of a kind of computer knitted circular knitting machine three cylinders, and it takes up room little, and scissors bit action is more steady.
Technology solution of the present utility model is as follows:
The pneumatic yarn change mechanism of computer knitted circular knitting machine three cylinders, comprise block entity, block entity is provided with three cylinder unit, each cylinder unit is by cylinder space, first hits piston rod and second hits piston rod composition, first hits piston rod and second hits piston rod sleeve in cylinder space, first hit piston rod expose block entity partial fixing limited location nut and cover have Stroke Control ring, block entity forms the first air inlet nozzle connect mutually with cylinder space with the second air inlet nozzle, first hits first of piston rod hits the right that plunger stem flange portion is positioned at the first air inlet nozzle, second hits second of piston rod hits the right that plunger stem flange portion is positioned at the second air inlet nozzle, cylinder cap and block entity are fixed together, second hits piston rod stretches out from the preset hole of cylinder cap.
Described cylinder cap is fixed together by screw and block entity.
Second of described wherein two cylinder unit hit the arrangement in parellel of piston rod, and second center of circle hitting piston rod of two cylinder unit is positioned on same vertical curve.
The beneficial effects of the utility model are:
1, due to its block entity being provided with three cylinder unit, so it takes up room little.
2, the mode that the piston rod of its each cylinder unit adopts secondary to advance drives scissors arm-tie, makes yarn have the process cushioned, not easily a stretch-broken yarn.Can not be hit excessive (causing excessive shock) to scissors arm-tie simultaneously, thus make scissors bit action more steady.
3, its each cylinder unit only has air inlet nozzle not have outlet nozzle, and scissors arm-tie homing action can not be too fast excessive, and it by extension spring, scissors arm-tie is replied slowly, further adds scissors bit traveling comfort.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of prior art;
Fig. 2 is the utility model form structure schematic diagram;
Fig. 3 is structural representation of the present utility model after cutting one of them cylinder unit open;
Fig. 4 is the right elevation of Fig. 1;
Fig. 5 is the left view of Fig. 1.
In figure: 1, block entity; 2, cylinder unit; 21, cylinder space; 21a, 21b, 22, first hit piston rod; 221, first plunger stem flange portion is hit; 23, second piston rod is hit; 231, second plunger stem flange portion is hit; 3, cylinder cap; 4, stop nut; 5, Stroke Control ring.
Embodiment:
Embodiment: see shown in Fig. 2 to 5, the pneumatic yarn change mechanism of computer knitted circular knitting machine three cylinders, comprise block entity 1, block entity 1 is provided with three cylinder unit 2, each cylinder unit 2 is by cylinder space 21, first hits piston rod 22 and second hits piston rod 23 and forms, first hits piston rod 22 and second hits piston rod 23 sleeve in cylinder space 21, first hit piston rod 22 expose block entity 1 partial fixing limited location nut 4 and cover have Stroke Control ring 5, block entity 1 forms the first air inlet nozzle 21a connect mutually with cylinder space 21 with the second air inlet nozzle 21b, first hits first of piston rod 22 hits the right that plunger stem flange portion 221 is positioned at the first air inlet nozzle 21a, second hits second of piston rod 23 hits the right that plunger stem flange portion 231 is positioned at the second air inlet nozzle 21b, cylinder cap 3 and block entity 1 are fixed together, second hits piston rod 23 stretches out from the preset hole of cylinder cap 3.
Described cylinder cap 3 is fixed together by screw and block entity 1.
Second of described wherein two cylinder unit 2 hit the arrangement in parellel of piston rod 23, and second center of circle hitting piston rod 23 of two cylinder unit 2 is positioned on same vertical curve L.
Working principle: due to its block entity 1 being provided with three cylinder unit 2, so it takes up room little.
During utility model works, as shown in Figure 3, the first air inlet of the first air inlet nozzle 21a, first hits piston rod 22 action promotes second and hits piston rod 23 first action one section to the right, then the second air inlet nozzle 21b again air inlet hit piston rod 23 whole process by second and send to the right.
Cylinder space 21 of the present utility model does not have outlet nozzle, only has the first air inlet nozzle 21a and the second air inlet nozzle 21b, air pump is filled with gas in cylinder space 21 when air pump stops pressurization, pressure in cylinder space 21 can reduce by nature, second hit piston rod 23 be pressed on the scissors arm-tie A3 shown in Fig. 1 together with, like this as extension spring A4 reset scissors arm-tie A3, second hits piston rod 23 can slowly move, scissors arm-tie homing action is not with pneumatic but reply slowly by extension spring, thus ensures scissors bit smooth running.
