Description

Oil nozzle

Technical field

The present invention relates to textile manufacturing machine, particularly a kind of oil nozzle, for jet lubrication oil.

Background technique

Lubricant oil is most important in textile manufacturing machine, and the hand especially for knitting machine lubricates, and requirement can have good lubrication effect, can not pollute textile again, and lubricant oil is injected on knitting machine by oil nozzle by the general pressurized air that adopts.As shown in Figure 1, existing oil nozzle is made up of jet pipe and fixed block, and this structure exists drawback: 1, when compressed-air actuated air pressure is not enough, oil dripping phenomenon appears in jet pipe, causes lubricant oil to waste and befouling environment; 2, lubricant oil sprays along straight passage, and the lubricant oil of injection place too disperses, and causes parts of lubricating oil not to be injected into predeterminated position, causes lubricant oil and pressurized air waste; 3, the elaioleucite of ejection is uneven, easily causes fabric contaminant or spindle; There is more yarn wadding in the air of 4, spinning and weaving workshop, what yarn wadding sticked to jet pipe goes out interruption-forming film, stops mixed oil and gas ejection, reduces lubrication effect.

Summary of the invention

The object of this invention is to provide a kind of oil nozzle, one or more in can solving the problem.

For achieving the above object, according to an aspect of the present invention, provide a kind of oil nozzle, comprise jet pipe, deflector and body, the end of jet pipe is connected with body, and deflector is positioned at jet pipe.Thus, the setting of deflector can increase the pressure of mixed oil and gas in jet pipe, makes in the grease ejected, and increases the utilization ratio of lubricant oil, and the elaioleucite of ejection is even, reduces pressurized air use amount, energy-conserving and environment-protective.When stopping oil spout, compressor return air, deflector retreats in jet pipe, remaining lubricant oil can be pushed back, prevent leakage of oil.

In some embodiments, deflector comprises center column and multiple guide plate, and multiple guide plate is axially set in the outer side surface of center column.Thus, the setting of guide plate can make orderly the entering in jet pipe of the mixed oil and gas in body.

In some embodiments, guide plate arranges inclined-plane near one end of nozzle exit.Thus, in lubricant oil course of injection, the setting on inclined-plane makes the end of guide plate and the inwall close contact of outside nozzle, prevents deflector from vibrating.

In some embodiments, multiple guide plate is uniformly distributed at the outer side surface of center column, thus mixed oil and gas is evenly sprayed from jet pipe, and then makes the elaioleucite of ejection even, prevents oil dripping.

In some embodiments, center column is provided with taper near one end of nozzle exit, and cone cylindrical body can be stretched out from nozzle exit.Thus, arranging of taper plays stream effect to the mixed oil and gas of jet pipe ejection, makes the elaioleucite of ejection even further, sprays and concentrate, prevent oil dripping, and taper stretches out from nozzle exit, can remove the yarn wadding that nozzle exit adheres to.

In some embodiments, arrange the connection chamber be connected and buffer cavity in body, jet pipe is connected with connection chamber.Thus, the setting of buffer cavity makes pressurized air and lubricant oil mix further.

In some embodiments, oil nozzle also comprises the connecting head be connected with body, and connecting head has through hole, and through hole is connected with jet pipe.Thus, the dismounting of oil nozzle is convenient in the setting of connecting head.

In some embodiments, the end sleeve of connecting head is provided with seal ring, is provided with the groove matched with seal ring inside body.Thus, the sealing realizing connecting head that arranges of seal ring is installed, and also achieves removably connecting of connecting head.

Beneficial effect of the present invention is: the deflector of this oil nozzle can increase the pressure of mixed oil and gas in jet pipe, makes in the grease ejected, and increases the utilization ratio of lubricant oil, and the elaioleucite of ejection is even, reduces pressurized air use amount; The setting of buffer cavity makes pressurized air and lubricant oil mix further, when stopping oil spout, and compressor return air, deflector retreats in jet pipe, remaining lubricant oil can be pushed back, prevent leakage of oil; Arranging of central body epicone body plays stream effect to the mixed oil and gas of jet pipe ejection, makes the elaioleucite of ejection even further, sprays and concentrate, prevent oil dripping, and taper stretches out from nozzle exit, can remove the yarn wadding that nozzle exit adheres to.The connecting head of oil nozzle is convenient to the dismounting of oil nozzle.In sum, oil nozzle of the present invention has saving pressurized air, improves lubricant oil utilization ratio, high lubricating effect, the simple advantage of structure.

Embodiment

Below in conjunction with accompanying drawing, the present invention is further detailed explanation.

Fig. 2 ~ 7 show schematically show the oil nozzle according to one embodiment of the present invention.

As shown in Figure 2, the oil nozzle of present embodiment comprises jet pipe 1, deflector 2 and body 3, and the end of jet pipe 1 is connected with body 3, and deflector 2 is positioned at jet pipe 1.

As shown in Figure 3 and Figure 4, deflector 2 comprises center column 21 and multiple guide plate 22, and multiple guide plates 22 are axially set in the outer side surface of center column 21.Center column 21 and guide plate 22 are integral type structure.One end that guide plate 22 exports near jet pipe 1 arranges inclined-plane 23.Multiple guide plate 22 is uniformly distributed at the outer side surface of center column 21, and the height of multiple guide plate 22 is equal, and the guide plate 22 of the present embodiment is five.One end that center column 21 exports near jet pipe 1 is provided with taper 24, and taper 24 and center column 21 are integral type structure.The formation space, edge that two adjacent baffle 22 and jet pipe 1 export, is convenient to mixed oil and gas and sprays from jet pipe 1.

As shown in Figure 5, arrange the connection chamber 31 be connected and buffer cavity 32 in body 3, jet pipe 1 is connected with connection chamber 31.Body 3 is also provided with joint 34, and joint 34 is fixedly connected with jet pipe 1.Joint 34 and body 3 are integral type structure.

Connection chamber 31 and buffer cavity 32 are cylindrical cavity, and the bottom surface 35 of buffer cavity 32 is in inverted cone, and the sidewall of connection chamber 31 is connected with the bottom surface 35 of buffer cavity 32.。
