Referring to fig. 1 to 5, a oiling device for a sewing machine includes: the oil outlet mechanism 1, a case 2 with an oil outlet, an oil cylinder and an oil pump; the oil cylinder and the oil pump are fixedly connected inside the case 2, and the oil cylinder is communicated with the oil outlet through the oil pump; the oil outlet mechanism 1 comprises an oil outlet pipe 3 with an output end 7 and an input end, and a rotor 4, wherein an oil outlet is communicated with the input end, the output end 7 is provided with a plurality of through holes 6, the oil outlets are annularly arranged around the axis of the oil outlet pipe 3, and the outer ends of the through holes 6 are fixedly provided with oil nozzles 5; rotor 4 sets up in oil pipe 3, and rotor 4's periphery and 3 inner walls of oil pipe rotate to be connected, have seted up the reposition of redundant personnel passageway 9 that link up on rotor 4, and reposition of redundant personnel passageway 9 one end communicates with arbitrary through-hole 6, and the other end link up rotor 4 and keeps away from the terminal surface of output 7. Wherein the plurality of nozzles 5 have different shapes and/or sizes.
Specifically, when the sewing machine is to be supplied with oil, the operator can select an oil supply portion and select an appropriate oil nozzle 5 according to the size of an oil filling hole or an oil filling gap of the oil supply portion, for example, in the case of a head cover and an end cover provided with the oil filling hole, the straight tube type oil nozzle 5 should be used for oil supply, and in the case of a component of a small size in the stitch sewing system, the taper tube type oil nozzle 5 of a corresponding size should be used for oil supply. After selection, the operator can rotate the rotor 4 so that the flow dividing passage 9 in the rotor 4 communicates with the through hole 6 in which the selected nozzle 5 is located, thereby communicating the selected nozzle 5 with the outlet pipe 3. At this time, the oil pump should be started to pump out the lubricating oil in the oil cylinder, and the lubricating oil sequentially passes through the oil outlet pipe 3, the flow dividing channel and the through hole 6 and finally flows out from the oil nozzle 5. That is to say, the operator can freely switch over the glib talker 5 of different sizes or shape through rotating rotor 4 to the different operating mode of adaptation improves oiling lubrication effect.
In addition, a speed regulator is fixedly installed in the case 2 and electrically connected with the oil pump. The rotating speed of the oil pump can be adjusted through the speed regulator, and the oil outlet speed is further controlled. The oil pump is a gear pump or a diaphragm pump, wherein the gear pump can discharge oil in positive rotation and absorb oil in negative rotation.
The shapes of the plurality of oil nozzles 5 comprise one or more of straight pipe shapes, conical shapes and L shapes, and an operator can select the proper oil nozzle 5 according to different working conditions.
As shown in fig. 2-5, further, the oil nozzle 5 includes a first tube 16, a cylindrical elastic oil film 10 and a second tube 17, one end of the first tube 16 is communicated with the through hole 6, and the second tube 17 is sleeved on the first tube; one end of the cylindrical elastic oil film 10 is fixedly connected with one end of the second pipe body 17 close to the through hole 6, and the other end of the cylindrical elastic oil film 10 is fixedly connected with one end of the first pipe body 16 far away from the through hole 6. Specifically, when oil is injected, the second tube 17 slides outwards and is pulled out of the first tube 16, so that the integral oil nozzle 5 extends, the cylindrical elastic oil film 10 is communicated with the first tube 16 and the second tube 17, and the second tube 17 can freely rotate after being pulled out of the first tube 16 to adjust the angle, thereby facilitating the oil injection operation; when the oil nozzle 5 is idle, the second tube 17 is sleeved on the first tube 16, and the cylindrical elastic oil film 10 is turned over and located between the first tube 16 and the second tube 17. That is to say, through set up cartridge type elastic oil film 10 between first body 16 and second body 17 for second body 17 can further extend, and deviate from behind first body 16, the operator can freely adjust the direction of second body 17, more convenient operation, the back is accomplished in the oiling, the operator with second body 17 suit again on first body 16, cartridge type elastic oil film 10 upset to between first body 16 and the second body 17, it is convenient to accomodate, and do not occupy extra space.
One end of the cylindrical elastic oil film 10 close to the first pipe body 16 is fixedly connected with a filter membrane 11. When the oil cylinder replenishes lubricating oil, the oil pump can be reversely rotated to absorb oil, and in the oil absorption process, the filter screen can filter impurities from the outer end of the oil nozzle 5 and the lubricating oil.
The second pipe body 17 is connected with the output end 7 through magnetic attraction, and when the oil nozzle 5 is not used, the initial position of the oil nozzle 5 is fixed, so that the oil nozzle can be taken down more conveniently when in use.
As shown in fig. 2 and fig. 3, further, a handle 12 is fixedly mounted on the outer circumferential surface of the rotor 4, a sliding groove 13 is formed on the oil outlet pipe 3, and the handle 12 is slidably connected with the sliding groove 13; the inner wall of the sliding groove 13 is provided with a groove, an elastic part and a protrusion 15 are arranged in the groove, the end part of the protrusion 15 is arched, the protrusion 15 is connected with the bottom of the groove through the elastic part, and the top end of the protrusion 15 extends out of the groove and extends into the sliding groove 13. Specifically, the operator switches the oil path to a different nozzle tip 5, and can rotate the rotor 4 by pulling the handle 12. And when the flow dividing channel 9 is communicated with any oil outlet, namely the rotor 4 is positioned at a working position, the handle 12 is clamped between two adjacent bulges 15 to form a working gear. That is to say, when changing the working position, the handle 12 needs to be pulled to jack up any protrusion 15, and then the next gear can be switched. By this arrangement, the handle 12 can be restrained within the station without sliding, enhancing the stability of the oil extraction, and the operator can concentrate on the condition of the oiling location without having to manually restrain the position of the rotor 4 so that it is fixed within the station.
