The utility model relates to the field of big circular needle machines, in particular to an improved buffer structure. The improved buffer structure is arranged between a driving arm and a cloth rolling machine and comprises two cavel bases, an outer cylinder body, a piston cylinder, a spring, a piston head, a piston rod and a porous accumulator, wherein the two cavel bases are arranged on the cloth rolling machine; the outer cylinder body is arranged on the cavel bases; the piston cylinder is arranged in the cylinder body; the spring is arranged in the piston cylinder; the piston head is propped against one end of the spring; the piston rod is arranged on one side of the piston head; the porous accumulator is sleeved on the piston rod; the outer cylindrical surface of the outer cylinder body is provided with thread; an oil-saving hole is formed in the wall of the piston cylinder; the piston head is I-shaped and is provided with a small right part and a big left part; a check baffle ring is sleeved on the piston head; the right end of the outer cylinder body is fixed on the cavel base on the right side; the outer end of the piston rod is fixed on the cavel base on the left side; a buffer sleeve at the lower end of the driving arm is sleeved on the outer cylinder body; nuts are locked on two sides of the buffer sleeve; and the driving arm is fixed on the outer cylinder body. The motion inertial force of the cloth rolling machine can be effectively absorbed when a machine stops and over 95 percent of impact force can be effectively absorbed, so that the knitting heart part can be protected and the service life of the whole machine is prolonged.

Description

A kind of follow-on buffer structure

Technical field

The utility model relates to big round needle machine field, is specifically related to a kind of follow-on buffer structure.

Background technology

Its transmission deep bid gear of tradition large circle machine (comprising large, medium and small circular knitting machine, single two-sided, stripper etc.) also need drive the batcher batching except that driving syringe work.Because circular knitting machine is when weaving cotton cloth; Often need temporary parking; Because batcher leans on the actuating arm of two symmetries to drive, and when stopping, often syringe heart knitting needle has been produced very strong inertia force; Unilateral bearing, knitting needle, syringe and fabric quality are produced destruction, and long-term use transmission from one channel to another influences machine life.

The utility model content

The purpose of the utility model provides a kind of follow-on buffer structure, in the time of can effectively slowing down batcher and stop to the impact of circular knitting machine.

A kind of follow-on buffer structure is located between actuating arm and the batcher, piston head, the piston rod of being located at the first side of piston of comprise the two goat's horn seats be located on the batcher, be installed on outer cylinder body on the goat's horn seat, be located at piston cylinder in the outer cylinder body, be located at spring in the piston cylinder, spring one end being located on the top, is sheathed on the cellular accumulator on the piston rod; Said outer cylinder body external cylindrical surface is a screw thread; Said piston in cylinder wall is provided with the fuel-economizing hole, and said piston head is I shape, and a right little left side is big; Be arranged with the non-return baffle ring on the said piston head; Said outer cylinder body right-hand member is fixed on the goat's horn seat of right side, and left side goat's horn seat is fixed in said piston rod outer end, and the cushion collar of said actuating arm lower end is placed on the outer cylinder body; The cushion collar both sides respectively lock a nut, and actuating arm 5 is fixed in outer cylinder body.

Said piston cylinder right half and outer cylinder body are combined closely, and between said piston cylinder left half and the outer cylinder body space are arranged, and said fuel-economizing is located at the gap in the hole.

Said upper cover of piston rod is provided with bearing, and said bearing is installed in the outer cylinder body, and said piston head and piston rod right-hand member are installed in the piston cylinder, are marked with oil in the piston cylinder.

In the time of effectively absorbing the machine operation parking, the motion inertia force of batcher can effectively absorb this impulse force more than 95%, thereby reaches the knitting cardiac component of protection, thus the service life of having improved complete machine.

The specific embodiment

Like Fig. 1, shown in Figure 2; A kind of follow-on buffer structure is located between actuating arm 5 and the batcher l, piston head 38, the piston rod 36 of being located at piston head 38 1 sides of comprise the two goat's horn seats 2 be located on the batcher, be installed on outer cylinder body 31 on the goat's horn seat 2, be located at piston cylinder 32 in the outer cylinder body 31, be located at spring 33 in the piston cylinder 32, spring 33 1 ends being located on the top, is sheathed on the cellular accumulator 35 on the piston rod 36; Said outer cylinder body 31 external cylindrical surfaces are screw thread; Said piston cylinder 32 walls are provided with fuel-economizing hole 34, and said piston head 38 is I shape, and a right little left side is big; Be arranged with non-return baffle ring 39 on the said piston head 38; Said outer cylinder body 31 right-hand members are fixed on the right side goat's horn seat 2, and left side sheep danger seat 2 is fixed in said piston rod 36 outer ends, and the cushion collar 4 of said actuating arm 5 lower ends is placed on the outer cylinder body 3l; Cushion collar 4 both sides respectively lock a nut 41, and actuating arm 5 is fixed in outer cylinder body 31.Be arranged with bearing 37 on the said piston rod 36, said bearing 37 is installed in the outer cylinder body 31, and said piston head 38 is installed in the piston cylinder 32 with piston rod 36 right-hand members, is marked with oil in the piston cylinder 32.The groundwork principle is: circular knitting machine, and when work runs up, the batcher 1 that leans on actuating arm 5 to drive; When stopping, the board running needs under the effect of unilateral bearing, to stop immediately, and at this moment batcher 1 is because effect of inertia produces an impulse force to actuating arm 5; Piston rod 36 motions; Non-return baffle ring 39 lifts slightly, and the compelled throttle orifice along piston cylinder 32 walls of oil gets into airtight born of the same parents' shape cellular accumulator 35 with piston.Along with the promotion of piston rod 36, block throttle orifice 34 gradually, so throttle orifice 34 districts reduce, when resetting, return spring 33 is pushed piston rod 36 to outside, and non-return baffle ring 29 is opened slightly, and oil flows back to piston cylinder 32 from apotheca accumulator 35.More piece discharge orifice buffer 35 has conventional, damping function progressive or self-compensation type.
