The mode of its oil-leakage-prevention is: differential retainer 2 is in front and back, the process that pumps, oil entrained by it can wiped off by the movable oil sealing 8 of the retainer in movable oil seal frame 7 to during movable oil seal frame 7 through retainer guide rail 4, and the oil scraped is along the inside flowing back to sewing machine case 1 in the movable oil sealing 8 of retainer and movable oil seal frame 7.
The major drawbacks of this oil-leakage-prevention mode is: when on differential retainer 2, larger oil mass enters movable oil seal frame 7, or retainer guide rail 4 and differential retainer 2 cause fit clearance bigger than normal during due to wearing and tearing, the oil sealing that there will be the movable oil sealing 8 of retainer is bad, cause unnecessary oil mass to flow to the outside of sewing machine case 1 from differential retainer 2 or move with differential retainer 2, machine vibration is thrown to tooth, causes leakage of oil.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oil-leakage-prevention retainer of industrial sewing machines, and it can avoid unnecessary oil mass to flow to outside casing from retainer or be thrown to tooth with retainer motion, machine vibration.
For solving the problems of the technologies described above, the technical solution of the oil-leakage-prevention retainer of the utility model industrial sewing machines is:
Comprise differential retainer, feed dog frame, differential retainer and feed dog frame are movably set on retainer guide rail, differential retainer and feed dog frame can before and after retainer guide rail, compound motion up and down; Retainer guide rail is fixedly installed on sewing machine case; Differential retainer and feed dog frame are arranged with movable oil seal frame, in movable oil seal frame, are set side by side with the movable oil sealing of at least two group retainers; Movable oil seal frame is fixedly connected with the end face of retainer guide rail, is provided with movable oil sealing between the end face of movable oil seal frame and retainer guide rail; Movable oil sealing and the movable oil-sealing sleeve of retainer are located on differential retainer and feed dog frame.
Described movable oil seal frame forms at least two cavitys arranged side by side, and each cavity is provided with the movable oil sealing of one group of retainer.
The installed surface of described retainer guide rail scribbles fluid sealant.
The installed surface of described movable oil seal frame scribbles fluid sealant.
The technique effect that the utility model can reach is:
The utility model utilizes a movable oil sealing oil resistance and the multiple oil resistance of four movable oil sealings of retainer, reaches the object of oil-leakage-prevention.
The utility model utilizes the oil resistance one by one of the movable oil sealing of multiple retainer, carries out mechanical type force oil return to the unnecessary oil mass of overlock machine retainer, thus the realization oil mass unnecessary to retainer effectively reclaims, and prevents retainer leakage of oil.
Be provided with movable oil sealing between retainer guide rail of the present utility model and movable oil seal frame, the long-pending oil to movable oil seal frame can be reduced, greatly the oil resistance pressure of reduction activity oil seal frame.
Movable oil seal frame of the present utility model is provided with two inner chambers, can increase anti-oil reservoir and oil-leakage-prevention distance, greatly improve the quality of Sewing machines.
The utility model structure is simple, and easy to operate, cost is low, easy to maintenance and improve the quality of Sewing machines.

Detailed description of the invention
As shown in Figures 2 to 6, the oil-leakage-prevention retainer of the utility model industrial sewing machines, comprise differential retainer 2, feed dog frame 3, differential retainer 2 and feed dog frame 3 are movably set on retainer guide rail 4, differential retainer 2 and feed dog frame 3 can before and after retainer guide rail 4, compound motion up and down;
Retainer guide rail 4 is fixedly installed on sewing machine case 1 by screw 5;
Differential retainer 2 and feed dog frame 3 are arranged with movable oil seal frame 7, in movable oil seal frame 7, are set side by side with the movable oil sealing 8 of four retainers; Movable oil seal frame 7 is fixedly connected with by the end face of screw 9 with retainer guide rail 4, be provided with the movable oil sealing 6 of oil resistant between movable oil seal frame 7 and the end face of retainer guide rail 4, the effect of movable oil sealing 6 is most oil to be blocked between retainer guide rail 4 and movable oil seal frame 7 to make the oil mass entered in movable oil seal frame 7 reduce;
Movable oil sealing 6 and the movable oil sealing 8 of retainer are sheathed on differential retainer 2 and feed dog frame 3;
The installed surface of retainer guide rail 4 and movable oil seal frame 7 scribbles fluid sealant.
As shown in Figure 7, movable oil seal frame 7 forms two cavitys (i.e. the first inner chamber and the second inner chamber) arranged side by side, in four movable oil sealings 8 of retainer, two components are two groups, and two groups of movable oil sealings 8 of retainer are arranged in two cavitys respectively, its role is to multiple oil of controlling one by one and reach oil-leakage-prevention effect.
Oil-leakage-prevention principle of the present utility model is as follows:
Sewing machine oil, in front and back, up and down compound motion process, is supplied differential retainer 2 and feed dog frame 3 by differential retainer 2 and feed dog frame 3, and the unnecessary oily part on differential retainer 2 and feed dog frame 3 directly flows back in sewing machine case 1; Another part oil moves with differential retainer 2 and feed dog frame 3 and arrives retainer guide rail 4 place, and when oil is through movable oil sealing 6 place, oil is greatly blocked in (first time oil resistance) between retainer guide rail 4 and movable oil seal frame 7 by movable oil sealing 6; A little long-pending oil carries out second time oil resistance at movable oil sealing 8 place of two retainers of the first inner chamber through movable oil seal frame 7; When the movable oil sealing 8 of two retainers of the first inner chamber effectively could not control unnecessary oil mass, unnecessary oil mass enters the second inner chamber of movable oil seal frame 7, and the movable oil sealing 8 of two retainers of the second inner chamber carries out third time oil resistance; Unnecessary long-pending oil is stayed in movable oil seal frame 7 in the mode scratched by four movable oil sealings 8 of retainer, and flows back in sewing machine case 1 along movable oil seal frame 7 and the movable oil sealing 8 of retainer, realizes mechanical type and forces oil return.
