Abstract
The utility model discloses an upper scissor mechanism used for a hosiery circular type knitting machine. The upper scissor mechanism is installed on a haff plate seat. A pair of disc scissors is arranged below the haff plate seat. The upper scissor mechanism comprises an upper scissor seat. The upper scissor seat is fixed on an air valve seat. An upper scissor pneumatic piston is arranged at the position, opposite to the upper scissor seat, of the air valve seat. An upper scissor rod is installed inside a hollow hole of the upper scissor seat. A pair of upper scissors is installed at the bottom end of the upper scissor rod. When the pair of upper scissors drops to the lowest point, the pair of upper scissors is matched with the pair of disc scissors. The upper scissor mechanism is mainly used for a combined action and being matched with the pair of disc scissors. The central point of the pair of disc scissors is used as a circumference point. The pair of disc scissors rotates under the control of a program. The upper scissor mechanism is fixed on the air valve seat and does not move. A kind of shearing force is generated through integration of motion and quietness so as to shear floating threads and excessive threads. The floating threads and the excessive threads are generated during a knitting process. According to the upper scissor mechanism used for the hosiery circular type knitting machine, shearing efficiency of waste threads and the excessive threads can be effectively improved, a machine failure rate is reduced, maintenance cost is directly saved for a user, and production efficiency is greatly improved.
Description
Technical field
The utility model belongs to technical field of knitting machinery, particularly a kind of upper shear mechanism for the hosiery circular knitting machine.
Background technology
Existing circular knitting machine is in the braiding process, machine is running up, when half-needle and knitting needle were done the tying double braid, old coil very easily floated, and then disturbed the work of half-needle and knitting needle, easily cause the bad phenomenon such as dropped stitch, knitting, make fabric produce flaw, reduced yields, and this phenomenon can produce wearing and tearing to half-needle and knitting needle, improve the probability that circular knitting machine damages, damaged user's economic interests.
Summary of the invention
In order to address the above problem, the utility model provides a kind of upper shear mechanism for the hosiery circular knitting machine, thereby reaches improved purpose.
adopt following technical scheme: a kind of upper shear mechanism for the hosiery circular knitting machine for this reason, be arranged on the half disc seat, there is a disc scissors half disc seat below, it comprises scissors base on, described upper scissors base is fixed on air valve seat, and scissors air rammer on is arranged on the relative position of air valve seat, it is characterized in that: described upper scissors base has a hollow hole and has horizontal upper in the hole, lower two-stage step surface, scissors bar on one is installed in the hollow hole of upper scissors base, scissors on one is installed in bottom at upper scissors bar, when upper scissors drops to minimum point, can match with disc scissors, described upper scissors is an inclined-plane at an end that contacts with disc scissors, described upper scissors and upper scissors bar are fixed by scissors screw on one and have certain interval between the two, the upper scissors bar outside by a scissors fixedly collar be fixed on upper scissors base, described scissors fixedly collar between the step surface of two-stage up and down of upper scissors base, also cover has a scissors stage clip outside upper scissors bar, described scissors stage clip is at higher level's step surface of upper scissors base and scissors fixedly between collar, has the scissors of lifting lever on higher level's step surface of upper scissors base, the described scissors lever top of lifting is fixed by hexagonal locking nut and plain washer, described scissors lever one end of lifting is between hexagonal locking nut and higher level's step surface, the other end is in the air rammer port, lift the position in scissors lever stage casing, have one to raise up on scissors base on this position, described projection is with to lift scissors lever stage casing inconsistent.
Technical scheme further, also have on higher level's step surface one with upper scissors bar axially parallel vertical through hole, a scissors blowing pipe is installed in the hole, described scissors blowing pipe lower end is in a side of upper scissors.
Upper shear mechanism is mainly to coordinate the disc scissors acting in conjunction, take the disc scissors central point as circumferential point, rotate at programme-control lower disc scissors, upper shear mechanism is fixed on air valve seat motionless, produces a kind of shearing force by being association of activity and inertia and shears flotation line and the remaining line that produces in the braiding process.Described upper shear mechanism when not working by on the scissors air rammer act on from top to bottom and lift on the scissors lever, lift the scissors leverage on the hexagonal locking nut according to lever principle, upper scissors bar and upper scissors are upwards lifted in the lump, reset by the scissors stage clip, can better prevent like this scissors wearing and tearing.Leave certain gap when in described upper shear mechanism, upper scissors being installed on upper scissors bar, and upper scissors and disc scissors contact jaw are designed to have constant slope, can prevent scissors wearing and tearing equally like this.And when on can by the processing of blowing of scissors blowing pipe, can prevent effectively that yarn from stopping up when cutting knife-edge part long-pending yarn and refuse yarn being arranged.Can effectively improve the shear efficiency of refuse yarn, remaining line by the utility model, reduce the generation of machine-spoiled rate, directly for the user saves maintenance cost, greatly improve production efficiency.
Description of drawings
Fig. 1 is the schematic diagram of the present embodiment.
The specific embodiment
Referring to accompanying drawing.the present embodiment comprises scissors base 41 on, and described upper scissors base 41 is fixed on air valve seat 2, and scissors air rammer 22 on is arranged on the relative position of air valve seat 2, upper scissors base 41 has a hollow hole and has horizontal upper in the hole, lower two-stage step surface, scissors bar 42 on one is installed in the hollow hole of upper scissors base 41, scissors 43 on one is installed in bottom at upper scissors bar 42, when upper scissors 43 drops to minimum point, can match with disc scissors, described upper scissors 43 is an inclined-plane 431 at an end that contacts with disc scissors 8, described upper scissors 43 and upper scissors bar 42 are fixed by scissors screw 44 on one and have certain interval 432 between the two, upper scissors bar 42 outsides by a scissors fixedly collar 45 be fixed on upper scissors base 41, described scissors fixedly collar 45 between the step surface of two-stage up and down of upper scissors base 41, also cover has a scissors stage clip 46 outside upper scissors bar 42, described scissors stage clip 46 is at higher level's step surface of upper scissors base 41 and scissors fixedly between collar 45, has the scissors of lifting lever 47 on higher level's step surface of upper scissors base 41, described scissors lever 47 tops of lifting are fixed by hexagonal locking nut 48 and plain washer, described scissors lever 47 1 ends of lifting are between hexagonal locking nut 48 and higher level's step surface, the other end is at air rammer port 21 places, lift the position in scissors lever 47 stage casings, have one to raise up on scissors base on this position, described projection is with to lift scissors lever 47 stage casings inconsistent, also have on higher level's step surface one with upper scissors bar axially parallel vertical through hole, a scissors blowing pipe 49 is installed in the hole, described scissors blowing pipe 49 lower ends are in a side of upper scissors 43.
