Problems solved by technology
Although the wrist bending machine in the prior art is equipped with a lubricating oil circuit, the amount of lubricating oil cannot be adjusted, and the amount of lubricating oil cannot be adjusted according to the operating speed of the wrist bending machine
For example, if the wrist bending machine operates at high speed, the amount of lubricating oil may be insufficient; while if the wrist bending machine operates at low speed, the amount of lubricating oil may be excessive, resulting in oil leakage, polluting the product and the working environment

The invention discloses a lubricating device of a feed-off-the-arm machine. The lubricating device of the feed-off-the-arm machine can correspondingly adjust the amount of lubricating oil according toworking conditions. According to the lubricating device of the feed-off-the-arm machine, oil channels which are used for the lubricating oil to flow through and communicate with one another are formed in an upper shaft, a needle bar crank, a crank shaft, a needle bar connecting rod and a needle bar connecting column of the lubricating device; the lubricating device of the feed-off-the-arm machinefurther comprises an oil quantity adjusting assembly; the oil quantity adjusting assembly comprises an oil quantity adjusting pin and an eccentric adjusting piece, the oil quantity adjusting pin is inserted in the upper shaft, an inner hole which communicates with the oil channels are formed in the inner end of the oil quantity adjusting pin, and is provided with an oil inlet and an oil outlet; and the eccentric adjusting piece can be rotatably arranged around the central line of the oil quantity adjusting pin, and sleeves the oil quantity adjusting pin, and one of end surfaces of the eccentric adjusting piece faces the oil outlet. When the eccentric adjusting piece is at a first position, the area of the portion, which is shielded by the eccentric adjusting piece, of the oil outlet is afirst shielding area; when the eccentric adjusting piece is at a second position, the area of the portion, which is shielded by the eccentric adjusting piece, of the oil outlet is a second shielding area; and the first shielding area is greater than the second shielding area.
Description
technical field [0001] The invention belongs to the field of sewing equipment, and in particular relates to a lubricating device for a wrist bending machine. Background technique [0002] The wrist bending machine is a kind of sewing equipment, which is suitable for sewing the side seam and cuff seam of denim jacket, the inner seam of jeans and the roll seam of various other thick fabrics. In the present cranking machine, the upper shaft of the rotation drives the needle bar crank to rotate, and the needle bar connecting rod connected with it moves up and down thereupon, thereby driving the needle bar lifting and lowering that is arranged on the lower end of the needle bar connecting rod so as to sew. The above-mentioned mechanism of the wrist bending machine has a plurality of movable connection parts, such as the rotating joint of the needle bar connecting rod and the needle bar crank, the rotating joint of the needle bar connecting rod and the needle bar, etc., due to the...
