Towel rapier loom

The utility model relates to the structural improvement of the portable towel rapier loom of a kind of cloth cover.

At present, the towel rapier loom that China uses has two kinds by fluffing principle branch: a kind of is the reed formula of floating, and another kind is the cloth cover movable type.The terry cloth loom that China produces adopts the reed formula of floating basically, many Neils (Dornier) towel rapier loom that China introduces belongs to the cloth cover movable type, wherein a kind of typical fluff mechanism and cloth cover batch form as shown in Figures 1 and 2, its concrete mechanism is: loop-pile controlling cam 16 rotates counterclockwise around loop-pile controlling cam axle 32, by roller arms 15, actuating cam fork 5 ' rotate counterclockwise around cam swing arm axle 33, driving back rest rocking arm 3 by back link 4 rotates counterclockwise around back rest rocker arm shaft 31, sending certain distance toward fell through face, simultaneously, cam swing 5 ' by front rod 8 drives and batches fork 9 and walk around work beam bolster 35 and rotate counterclockwise, through planetary gear 10 and planetary gear 11 work beam 13 is rotated counterclockwise around work beam bolster 35, cloth cover is deflected from fell.Loop-pile controlling cam 16 continues to rotate counterclockwise around loop-pile controlling cam axle 32, clockwise rotate around cam swing arm axle 33 by roller arms 15 actuating cam forks 5, by back link 4, back rest rocking arm 3 is clockwise rotated around back rest rocker arm shaft 31, deflecting from fell through face, simultaneously, cam swing 5 batches fork 9 by front rod 8 drives and clockwise rotates around work beam bolster 35, through planetary gear 10 and planetary gear 11 work beam 13 is clockwise rotated around work beam bolster 35, cloth cover is sent toward fell, for the formation of looped pile provides certain warp thread amount.

The motion of work beam 13 is synthetic by two parts, a part is from the fluffing motion, another part is from the controlled motion of filling density, this is two-part move through by being connected planetary gears that the central gear, planetary gear 10, planetary gear 11, central gear 14, the pinion frame 12 that batch on the fork 9 form synthetic.Central gear 14 is connected with filling density campaign input 17 (being pickwheel), batching fork 9 links to each other with the fluffing motion, this planetary gears is batching the motion of fork 9 and the motion of central gear 14 is compound on the pinion frame 12, pinion frame 12 from the center of central gear 14 by being connected with work beam 13.The input of the input of filling density controlled motion and fluffing motion is all on the right side of work beam.

Rapier looms fluff mechanism shown in the accompanying drawing 3 is a kind of structural improvement to said mechanism, it mainly be original by cam swing arm 5, front rod 8, batch in the quadric chain that fork 9 forms and increased transition fork 7 and middle connecting rod 6, form a cover six bar mechanism transmission campaign, all the other motions are identical with the front.

On the other hand, at the widely used many Rapier loomss of China, as imitative SM92, the GA731 of SM93 series, GA731B type loom, though it is light and handy to have structure, easy to operate, the characteristics that the ratio of performance to price is excellent, but the also untapped towel rapier loom that goes out to be fit to China's national situation on this type, because the cloth cover of this loom batches the different of form and many Neils (Dornier), be that cloth cover is through batching backplate, around to its top (opposite with the direction shown in accompanying drawing 1 or the accompanying drawing 3), the fluff mechanism that makes it aforementioned many Neils loom can't be applied on such loom from the below of work beam.Therefore, such Rapier looms can only be used to weave the plain cloth fabric so far, still can't carry out the production of towel cloth.

Goal of the invention of the present utility model provides a kind of rational in infrastructure, can be at cloth cover through batching backplate, around the loom of the form of batching above it fluff mechanism is set from the below of work beam, and helps alleviating the stressed of frame, reduce the towel rapier loom of loom vibration.

Another purpose of invention of the present utility model provides the towel rapier loom that fluff mechanism is set on the loom of homonymy that a kind of filling density campaign and fluffing motion can not be arranged on work beam.

Goal of the invention of the present utility model mainly is achieved by following technology: the two ends of described work beam are respectively arranged with filling density campaign input and have the fork that batches of fluffing motion input action; And the fork that batches that is hinged with front rod is done counter motion all the time with the back rest rocking arm that is hinged with back link; Pinion frame is connected from the outside and the work beam of central gear.Like this, the configuration fluff mechanism is become a reality, and owing to the direction of motion of batching swing arm and back rest rocking arm is opposite all the time, the inertia force that makes it entire mechanism is offset a part, thereby alleviated the stressed of frame, reduced the vibration of loom.

Described transition fork axle be arranged on front rod and in the top of connecting rod, its preceding transition fork and front rod are hinged, connecting rod links to each other with cam swing on being arranged on the cam swing arm axle in its transition fork warp, forms a quadric chain.Certainly, described transition fork axle also can be arranged on the below of front rod, and all the other structures are basic identical, make be arranged at its two ends batch swing arm and back rest rocking arm is done rightabout motion equally all the time.

Usually, described cam swing arm and back link arm can be separately positioned on the both sides of cam swing arm axle, and the coaxial roller arms that also is provided with, and three arms are solidly fixed, all the time be fixed against loop-pile controlling cam under the spring force effect, the back link arm links to each other in back rest rocking arm through back link.

Therefore, the utlity model has rational in infrastructurely, cost is lower, can save a large amount of foreign exchanges, weaving performance is better, the production efficiency height, good product quality, wide adaptability, characteristics such as easy and simple to handle, and improved and weaved environment (noise), reduce labor strength, be a kind of towel rapier loom new architecture that is suitable for China's national situation.
