Abstract

The utility model discloses a yarn chopping machine for tail yarns. In a circular weaving process, yarns are resided on a tube when the yarns wound on a metal yarn tube are almostly used up; tail yarn tubes are centrally poured into an oscillator and are conveyed to a V-shaped groove through a conveyor belt; a cutting air cylinder acts to cut off the yarns; then a push air cylinder acts to push the yarns and the yarn tubes together to the lower part of an electromagnetic chuck; the electromagnetic chuck acts to apply an upward action force to the yarn tubes; grooves on the yarn tubes have guidance quality; under the common action of the push air cylinder, the electromagnetic chuck and the grooves, the yarn tubes enter round holes on a yarn tube box; the yarn tubes are separated from the yarns and fall into the yarn tube box and the yarns enter the yarn box under the action of dead weight; and next circulation starts after one circulation is finished and the batch separation of the yarns from the yarn tubes can be finished. The yarn chopping machine is safe and reliable; and the yield of the equipment is improved, the labor intensity of circular weaving workers is reduced and the scrap quantity of the yarn tubes is reduced.

Description

The yarn cutting machine of tail yarn

Technical field

The utility model relates to a kind of device that reclaims yarn on the tail spool, particularly a kind of yarn cutting machine of tail yarn.

Background technology

Yarn on traditional removing tail spool is to adopt manual method to handle, and promptly manpower is held single tail spool, cuts off flat filament with knife, the situation that hand is scratched by cutter appears in this processing mode easily, a lot of tool marks can appear in the spool outer surface, and tool marks are too many, and spool will be scrapped.Cut the tail spool and generally be the operating personnel on the circular loom,, certainly will influence circle and knit output, and manually-operated efficient is low because of cutting the spool holding time.The existing exploitation of existing tail yarn treatment facility, announced a kind of full automatic treatment machine of tail spool as Chinese patent: CN2175242Y, its structure is to be provided with to comprise an oscillator on a pedestal, one inclined rail seat, its upper end is connected with the oscillator exit, its lower end is in transverse onveyer top, in the perpendicular direction setting of transverse onveyer destination county always to conveyer belt, one some bocca that forms a line is mounted on directly to conveyer belt centre top, with directly one baffle plate is set to the be separated by opposite of a distance of conveyer belt terminal point, the baffle plate back is provided with a taper slide and constitutes.The problem that this equipment exists is, the tail yarn generally all is polyethylene, polypropylene or other resin material, running into naked light will burn, the burning of tail yarn not only wastes raw material, and exist to pollute, safety inadequately, in addition, in service at equipment, spool can not each all just can be arranged on centre bore on the baffle plate by it.

Summary of the invention

At the existing in prior technology problem, the purpose of this utility model be exploitation a kind of safe, reliable, output is high, reduces labor intensity of operating staff, reduce spool and scrap the tail yarn yarn cutting machine of quantity.

The technical solution of the utility model is: comprise frame, conveyer belt, the vibration feeder, promote cylinder, yarn case and spool case, promote cylinder by electromagnetic valve and travel switch control, it is characterized in that: the upper end at conveyer belt is provided with hot knife, be provided with the V-type groove under the hot knife, the V-type channel opening faces up, be provided with magnechuck at hot knife and V-type groove end, hot knife can be single resistance wire, perhaps on the copper billet electric heater is installed, the hot knife back side is connected with the cutting ejecting rod of cylinder, the cutting cylinder block is connected with frame, and the action control hot knife of cutting cylinder moves up and down and cuts, and magnechuck is provided with the groove of circular arc, be provided with movable pulley or scroll wheel in the groove, slot opening faces down, and after the action of cutting cylinder, yarn is fused, then promote the cylinder action, magnechuck action is simultaneously pushed spool on the spool case circular hole, and the yarn case is below magnechuck, the spool case is in magnechuck one side, promote cylinder and cutting cylinder respectively by solenoid control, electromagnetic valve cooperates its action of control by travel switch with relay, and the hot knife heating-up temperature is at 165 ℃ to 450 ℃.

The utility model adopts hot knife that the tail spool is cut, the heating-up temperature of hot knife is 165 ℃ to 450 ℃, this temperature range, be higher than the polypropylene softening temperature, the end, cut off polypropylene flat filament hot melt in its burning-point, solved the problem of yarn burning, device security obviously improves, and the V-type groove guarantees that spool is concentric with the hot knife axis, after the cutting, the action of promotion cylinder, magnechuck applies active force to spool, and the groove on it improves the spool guidance quality, guarantees that spool enters the circular hole on the spool case, guarantee that spool separates with yarn, equipment dependability obviously improves, and adopts cylinder control appliance action stage by stage, has obviously improved equipment yield.The operation of this equipment has reduced round weaver people's labour intensity, and has improved the output of last one procedure indirectly, after cutting is finished, the action of promotion cylinder is together shifted yarn and spool onto the magnechuck lower position, the magnechuck action, spool is subjected to active force upwards, be subjected to promoting the active force of cylinder simultaneously, the circular hole on the spool operation spool case, the diameter in hole is a bit larger tham the spool diameter, yarn after the cutting falls into the yarn case at the active force of circular hole, and spool falls into the spool case after passing circular hole.

The specific embodiment

The utility model comprises frame, conveyer belt, the vibration feeder, promote cylinder, yarn case and spool case, promote cylinder by electromagnetic valve and travel switch control, it is characterized in that: the upper end at conveyer belt is provided with hot knife, be provided with the V-type groove under the hot knife, the V-type channel opening faces up, be provided with magnechuck at hot knife and V-type groove end, hot knife can be single resistance wire, perhaps on the copper billet electric heater is installed, the hot knife back side is connected with the cutting ejecting rod of cylinder, the cutting cylinder block is connected with frame, and the action control hot knife of cutting cylinder moves up and down and cuts, and magnechuck is provided with the groove of circular arc, be provided with movable pulley or scroll wheel in the groove, slot opening faces down, and after the action of cutting cylinder, yarn is fused, then promote the cylinder action, magnechuck action is simultaneously pushed spool on the spool case circular hole, and the yarn case is below magnechuck, the spool case is in magnechuck one side, promote cylinder and cutting cylinder respectively by solenoid control, electromagnetic valve cooperates its action of control by travel switch with relay, and the hot knife temperature is at 165 ℃ to 450 ℃.

Its operating principle is the tail spool to be concentrated pour in the oscillator, conveyer belt transports spool to the V-type groove, the action of cutting cylinder, cut off yarn, then promote the cylinder action, yarn and spool are pushed into the magnechuck bottom together, the magnechuck action, apply active force upwards to spool, groove on it has guidance quality, is promoting cylinder, magnechuck, under the acting in conjunction of groove, spool enters the circular hole on the spool case, spool separates with yarn, spool falls into the spool case, and yarn enters the yarn case under the deadweight effect, after a circulation is finished, next actuation cycle begins, and the batch of finishing yarn and spool separates.
