Best, the supporting base that the sealed pressure vessel of lubricating oil is housed in tank body has and is connected external container, pressing body is movably arranged on the supporting base.
Best, in pressing body and spool, be formed with the fuel injection passage of perforation, this fuel injection passage one end is communicated with spray bar, the other end is opened on spool and forms oil-in, and spool remains on the position of a sealing oil-in and can be driven into a position of opening oil-in by pressing body by spring.
Best, cylinder is the single effect cylinder.
Best, solenoid directional control valve is the two-position three way solenoid directional control valve.
The auto-jet lubrication device of the round needle loom that the utility model provides is a kind of simple and practical device according to the design of mechanical lubrication principle.During knitting operation, the control device of round needle loom is according to the operating state of needle selection device, color change head, the action of control solenoid directional control valve, make Compressed Gas enter cylinder and promote piston rod movement, affact on the pressing body of oil tank and spool is slided, thereby make lubricating oil be ejected into the mechanical movement part of needle selection device, color change head, alleviate the friction and wear of parts, thereby can prolong the service life of needle selection device, color change head effectively by spray bar.
Below, the structure and the beneficial effect of the auto-jet lubrication device of the round needle loom that the utility model is provided by specific embodiment are elaborated.

Fig. 2 is the cut-away view of the oil tank of auto-jet lubrication device shown in Figure 1.
Fig. 3 is the partial enlarged drawing of A part among Fig. 2.
Fig. 4 is the schematic diagram of the solenoid directional control valve of auto-jet lubrication device shown in Figure 1.
Preferred forms
The auto-jet lubrication device that the utility model provides is used for the needle selection device to the round needle loom, the mechanical moving element of color change head carries out automatic splash lubrication.Described mechanical moving element is the line transfer finger mechanism of needle selecting foot, the color change head of needle selection device and trimming clamp mechanism etc. for example, and these parts frequent movement, phase mutual friction when knitting operation variable color line transfer need oil jet lubrication.
Referring to figs. 1 through Fig. 4, the auto-jet lubrication device of round needle loom comprises pedestal, oil tank, cylinder and solenoid directional control valve.
Pedestal 1 can be installed near the frame the needle selection device, color change head of round needle loom.
Oil tank, be fixedly installed on the pedestal 1, it comprises by interior and the sealed pressure vessel 21 of lubricating oil is housed and is arranged on tank body that the supporting base 22 of container 21 outsides constitutes, is movably arranged on pressing body 23 on the supporting base 22, is connected spray bar 24 on the pressing body 23, valve seat 25 in the container 21 is set, is slidably disposed in the valve seat 25 and the spool 26 that is connected with pressing body 23, the oil guide pipe 28 that holds the spring 27 between valve seat 25 and spool 26 and be communicated with valve seat 25.Be formed with the fuel injection passage 29 of perforation in pressing body 23 and spool 26, these fuel injection passage 29 1 ends are communicated with spray bar 24, the other end is opened on spool 26 and forms oil-in 261.Spool 26 remains on 261 sealed 262 positions that seal of oil-in by spring 27, and spool 26 can slide into oil-in 261 by pressing body 23 drivings and break away from the position of seals 262 sealings.
Solenoid directional control valve 4, be the two-position three way solenoid directional control valve, this valve has air inlet 41, gas outlet 42, exhaust outlet 43 and Electromagnetic Control end 44, and its air inlet 41 connects source of the gas, gas outlet 42 is communicated with the pore of cylinder, and Electromagnetic Control end 44 is electrically connected with the Computer Control Unit of round needle loom.
Below, the operation principle of auto-jet lubrication device is briefly described.Auto-jet lubrication device is installed in the appropriate location of round needle loom, and the mechanical moving element that spray bar aligning needle selection device, color change head need be lubricated.When carrying out knitting operation, the Computer Control Unit of round needle loom is according to the duty of needle selection device, color change head, frequent degree, activity duration as action, determine whether to carry out oil jet lubrication, and send instruction control solenoid directional control valve 4 and carry out corresponding actions.When the needs oil jet lubrication, make the air inlet 41 of solenoid directional control valve 4 be communicated with gas outlet 42, close exhaust outlet 43, Compressed Gas enters 31 motions of cylinder 3 promotion piston rods and stretches out, drive the pressing body 23 of oil tank, drive spool 26 slips and make oil-in 261 break away from seals 262 sealings, lubricating oil enters fuel injection passage 29 from oil guide pipe 28 through oil-in 261, is ejected into the mechanical movement part of needle selection device, color change head at last by spray bar 24.And when not needing oil jet lubrication, 4 actions of control device control solenoid directional control valve make gas outlet 42 be communicated with exhaust outlet 43, close air inlet 41, gas in the cylinder 3 is discharged, piston rod withdrawal disengaging contacts with pressing body 23, spool 26 is return under spring 27 effects, thereby remain on the position sealing fuel injection passage 29 of 261 sealed 262 sealings of oil-in, stop oil spout.
Certainly, the Computer Control Unit of round needle loom also can periodically send instruction control solenoid directional control valve 4 and carry out corresponding actions, to realize regularly oil jet lubrication.
