Description
Technical field
The utility model relates to industrial sewing equipment manufacturing technology field, especially refers to a kind of lubricating arrangement of blind stitching machine.
Background technology
Technical staff of the same trade is generally more clearly, and in the industrial sewing apparatus field, blind stitching machine is a kind of sewing device that products such as clothes, trousers, socks and gloves close up that is used for.Along with the cancellation of China joined WTO and weaving quota, the blind stitching machine equipment many places in most weavings, the garment enterprise almost are non-stop runs in 24 hours in the fully loaded duty.Early stage blind stitching machine equipment adopts the hand oiling mode to be lubricated more, and not only work efficiency is low, and lubricant effect is poor, the lubricating oil product waste is many.Therefore how to keep the drive disk assembly of blind stitching machine to be in good lubricated environment, be the technical barrier that technical staff of the same trade needs to be resolved hurrily always.State Intellectual Property Office disclosed the patent No. and was called " blind stitching machine of automatic lubrication installation " for the ZL02261302.1 name on October 29th, 2003, this product " by main shaft and be contained in the rotation of the oil pump eccentric bushing on the main shaft; drive the oil sucting cavity, the fuel sucking pipe oil suction that are fixed on the body; and mist of oil is sprayed to each tumbler in the body by flowline, thus improve the condition of work of lubricated part in the blind stitching machine.Needn't establish motor in addition, drive the main shaft rotation by original electrical motor of sewing machine and can realize self-lubricated purpose." but applicant by to its specification scrutinizing in full; find that this product still has deficiency; mainly show: owing to be to utilize the rotation of eccentric bushing to finish the oil suction action; cause the fuel delivery of lubricating arrangement little; can only form the defective that mist of oil is lubricated, the blind stitching machine that can not satisfy part high load capacity, long time continuous working lubricates required; In addition, the fuel delivery of this series products can not be regulated as required.For this reason, people's expectation has the auto-jet lubrication device that a kind of fuel delivery is big, oil pressure is stable to appear on the market, and operates at full capacity required continuously with the blind stitching machine that satisfies in numerous clothes, the textile enterprise.
The utility model content
The technical problems to be solved in the utility model is that the lubricating arrangement that overcomes existing blind stitching machine technical field utilizes eccentric bushing to rotate defective and the deficiency that the fuel delivery of finishing oil suction and causing is little, can only form fog lubrication, provide the auto-jet lubrication device that a kind of fuel delivery is big, oil pressure is stable to society, and fuel delivery can be regulated as required, and blind stitching machine in numerous clothes, the textile enterprise is operated at full capacity continuously and to process different classes of product required to satisfy.
The technical scheme that its technical problem that solves the utility model adopts is: the auto-jet lubrication device of blind stitching machine, comprise the fuel sucking pipe of the pump housing, bottom and the spray bar of side, establish oil sucting cavity in the described pump housing, be provided with the piston rod that is used to draw lubricating oil in the oil sucting cavity; Described oil sucting cavity lower end is connected with horizontal oil leab, and described oil leab below communicates with fuel sucking pipe through check valve, and described oil leab top communicates with spray bar through check valve.
Described check valve is that the vertical oil duct of cone and one are located at its inner steel ball and constitute by the bottom.
The port of described fuel sucking pipe is provided with the filter oil net.
Described piston rod is spun mutually by upper boom and lower beam and forms.
The auto-jet lubrication device of the utility model blind stitching machine adopts the reciprocating motion mode of piston rod in vertical direction, and absorption and ejection lubricating oil lubricate the drive disk assembly of blind stitching machine, have the advantage that fuel delivery is big, oil pressure is stable.Described piston rod is spun mutually by upper boom and lower beam and forms, and entire length can be regulated, and makes the variable volume of oil sucting cavity.Therefore under the prerequisite of the same rotating speed power of input, increase the formation speed difference of negative pressure, thereby produce different fuel deliveries.The utility model is compared than prior art, and not only big, the oil pressure of fuel delivery is stable, and fuel delivery can also regulate as required, can satisfy extensively that blind stitching machine in numerous clothes, the textile enterprise is operated at full capacity continuously and to process different classes of product required.
Description of drawings
Fig. 1 is the utility model product structure schematic diagram.
The specific embodiment
As shown in Figure 1, the auto-jet lubrication device of the utility model blind stitching machine, comprise the pump housing 18, be connected to the fuel sucking pipe 12 of the pump housing 18 bottoms and the spray bar 7 of side, be provided with Connection Block 8 between the pump housing 18 and the spray bar 7, come off from the pump housing 18 behind the spray bar 7 interface pressurizeds preventing.Establish oil sucting cavity 17 in the pump housing 18, be provided with the piston rod 6 that is used to draw lubricating oil in the oil sucting cavity 17.The lower end of oil sucting cavity 17 is connected with horizontal oil leab 11, and described oil leab 11 belows are the check valve of vertical oil duct 15 compositions of cone via steel ball 14 and bottom, communicate with fuel sucking pipe 12.Described oil leab 11 tops are similarly the check valve that the vertical oil duct 9 of cone is formed via steel ball 10 and bottom, communicate with spray bar 7.In order to prevent that impurity from entering the utility model device inside, cause the wearing and tearing of blind stitching machine transmission parts then, be provided with filter oil net 13 at the port of fuel sucking pipe 12.For the ease of the laterally processing and manufacturing of oil leab 11, the pump housing 18 can adopt two metalworks superimposed mutually, and middle lining gets final product with annular shim 16.
The rotatable parts that piston rod 6 of the present utility model can be directly connected in the blind stitching machine are imported as power.As shown in Figure 1, the power source of this piston rod 6 is from the big connecting rod 1 of blind stitching machine.During work, big connecting rod 1 drive fork 2 is done the reciprocating motion on the vertical direction, through brace 3, adapter sleeve 5, drives piston rod 6 pumping in oil sucting cavity 17, thereby finishes the oil suction action.When piston rod 6 made progress, oil sucting cavity 17 volumes increased, and produced negative pressure, and lubricating oil enters oil duct 15 by fuel sucking pipe 12, process oil cleaner screen 13, and promotes to move on the steel ball 14, and lubricating oil enters horizontal oil leab 11 by the slit between steel ball 14 and the oil duct 15.When piston rod 6 downwards the time, oil sucting cavity 17 volumes reduce, and produce supercharging, and steel ball 14 is adjacent to the cone bottom of oil duct 15, and inlet port is closed.Simultaneously, oil sucting cavity 17 volumes reduce to produce supercharging to be promoted to move on the steel ball 10, and lubricating oil from spray bar 7 ejections, supplies each drive disk assembly of blind stitching machine lubricated by the slit between steel ball 10 and the oil duct 9.
In order to regulate the size of fuel delivery at any time, piston rod 6 of the present utility model is spun mutually by upper boom 20 and lower beam 19 and forms.After unclamping screw 4, can rotate upper boom 20, regulate the length that lower beam 19 enters oil sucting cavity 17, the volume of oil sucting cavity 17 is changed, under the prerequisite of the same rotating speed power of input, increase, the formation speed difference of negative pressure, thereby produce different fuel deliveries.
