Description
Technical field
The invention belongs to field of textiles, relate to a kind of tension-adjusting gear,, can realize that many weft yarns feed a main burner simultaneously and introduce shed open simultaneously by of the adjusting of this device to weft tension.
Background technology
Air-jet loom is to adopt the jet-stream wind weft traction to pass through the shuttleless loom of shed open.Its operation principle is to use air as the wefting insertion medium, with the compressed air stream that ejects weft yarn is produced frictional traction and draws, and the weft yarn band is crossed shed open, reaches the purpose of wefting insertion.This filling insertion way can make loom realize the high speed high yield.In several shuttleless looms, air-jet loom is the highest a kind of of the speed of a motor vehicle, because filling insertion way is reasonable, it is higher to go into the latitude rate, the running operation handy and safe, and it is wider to have a varietal adaptation, machine material consumption is few, the efficient height, advantage such as speed of a motor vehicle height, noise are low has become one of novel cloth machine of tool development prospect.Because air-jet loom adopts air-flow latitude mode, maximum shortcoming is that energy consumption is higher.
The weft accumulator of the disclosed a kind of loom specialty of Chinese invention patent ZL98118743.9 and yarn feeding method thereof overcome prior art utilize spring to realize the location of detecting element and reset the spring fatigue that brought and the detection system generation obstacle, the detection signal that cause transmit not in place, for a series of defectives such as yarn difficulty or confusions, thereby make detecting element correctly detect spinning velocity, through fuzzy recognition repeatedly repeatedly, thereby make yarn feeding amount and loom reach balance to the consumption of yarn.Its advantage is simple in structure, cheap, and is strong to thickness of yarn adaptability, can make the reset speed of detecting element catch up with the needs of loom.
The weft inserting apparatus of the disclosed a kind of air-jet loom of Chinese invention patent ZL95109948.5 uses the weft inserting apparatus of special-shaped reed to be provided with the metal reed member of a plurality of band C type grooves, and these metal reed members constitute from the weft yarn passage of the weft yarn flight of main burner ejection.Each groove has the upper wall of parallel floor, and the lower wall that broadens gradually towards opening connects upper wall with the last connecting portion of dark wall and dark wall is connected in the following connecting portion of lower wall.The radius of curvature of last connecting portion is equal to or less than 1mm, and the radius of curvature of following connecting portion is greater than the radius of curvature of last connecting portion.
Chinese invention patent application 200710016202.5 disclosed a kind of high-speed four-jet air-jet looms comprise shedding mechanism, weft insertion device, the good spooler of warp-feeding mechanism, weft insertion device comprises pressure-reducing valve, high frequency valve and nozzle, described nozzle comprises four fixed nozzles and a moving nozzle, four fixed nozzles are arranged side by side the place ahead at weft accumulator, and moving nozzle is arranged on the place ahead of fixed nozzle; Adopt active type conjugate cam shedding mechanism, and balance back rest mechanism, and adopt independently spooler.Loom of the present invention can be weaved the yarn of multiple different colours different size, has improved wefting insertion rate and weave quality.
Have much by the patent of improving air-jet loom filling insertion way, nozzle and storage latitude method raising air-jet loom efficient, be not well solved but the air compressor energy that air-jet loom causes because of the employing air-jet weft insertion consumes high problem.
Summary of the invention
The purpose of this invention is to provide the pneumatic picking tension-adjusting gear that a kind of many weft yarns are introduced simultaneously, after the yarn of multitube different material, different qualities regulated yarn tension through this device respectively, introduce same weft accumulator simultaneously, and introduce shed open simultaneously and weave, with the work number of times that solves nozzle in the prior art too much, the number of times of shedding too much and the excessive problem of energy consumption of air-jet loom.
The pneumatic picking tension-adjusting gear that many weft yarns of the present invention are introduced simultaneously comprises base, thread guide eyelet, bolt, nut, spring, first tension piece and second tension piece with platform.More than one thread guide eyelet is arranged on the base platform, has between the thread guide eyelet at interval; One bolt vertical fixing is in base platform one end, and bolt is provided with nut and matches with bolt; Spring one end is fixed in nut, and the other end is fixed in first tension piece; Second tension piece is relative with first tension piece and be fixed on the bolt, second tension piece from the distance of base (platform) less than the distance of first tension piece from base (platform).
Interval between the described thread guide eyelet equates.
Yarn is between first tension piece and second tension piece and in thread guide eyelet.By the high and low position of adjusting nut on bolt, make spring exert pressure for first tension piece, first tension piece and the second tension piece clamping yarn, thus apply different tension force to yarn.
The pneumatic picking tension-adjusting gear that many weft yarns of the present invention are introduced simultaneously also comprises twizzle and automatic stop arrangement.Wherein, twizzle one end is connected with automatic stop arrangement; Automatic stop arrangement is fixed in described base with platform, is connected to air-jet loom by binding post on it.
Described twizzle contacts with yarn, and when yarn breakage or when not having yarn, twizzle can be bound to vertical position, thereby make automatic stop arrangement produce a signal of telecommunication, automatic stop arrangement is connected to air-jet loom by binding post, and under the control of air-jet loom control circuit, loom quits work.
Connect mutually by the binding post on the automatic stop arrangement, can control a plurality of tension-adjusting gear of the present invention simultaneously.When the twizzle of arbitrary tension-adjusting gear was bound to vertical state, the signal of telecommunication that the automatic stop arrangement in this tensioner produces can make that all air-jet loom quits work.
The beneficial effect that the present invention realizes:
The present invention is by having realized the adjusting of pneumatic picking tension force at the device with parts such as thread guide eyelet, bolt, nut, spring, first tension piece and second tension piece are set on the base of platform.Each this tensioner is used for regulating the tension force of a weft yarn, after many weft yarns of different material and quality carry out tension adjustment by this tensioner, can enter a weft accumulator simultaneously and by the ejection of same nozzle.Thereby realized reducing nozzle the work number of times, reduce the shedding number of times and save the effect of the energy consumption of air-jet loom.
The present invention unites use by binding post with many tension-adjusting gears, has increased the storage latitude ability of weft accumulator to different weft yarns greatly, and then has increased the diversity of raw material or pattern greatly.
