Tufting bayonet equipment with tufting rifle grasping mechanism
Technical field
The present invention relates to a kind of tufted carpet process equipment, more specifically to a kind of tufting bayonet equipment with tufting rifle grasping mechanism.
Background technology
Tufted carpet originates from the State of Georgia, US in 19th century.At first because of its outward appearance as the lawn, so claim turf (turf) fabric again.30~forties of 20th century, tufted carpet develops into row's pin synthetic tuft by the single needle synthetic tuft.The tufted carpet of jacquard weave and stamp appears again in the fifties, and popularizes in European and American countries gradually.Since the sixties, tufted carpet is main raw material with the chemical fibre, and fabric width reaches 4~5 meters.Because wide in variety, production efficiency is high, cost performance is high, so tufted carpet become output in the machine-made carpet maximum, use the widest kind.
The processing technology of tufted carpet is:
1, material is prepared, and the tacryl that preheating is finalized the design is woven into base fabric and the required various chemical fibre yarns of synthetic tuft.
2, synthetic tuft typing is promptly with synthetic tuft equipment (row of being generally pin machinery) leader tape chemical fibre yarn whole row, synthetic tuft at high speed on the tacryl base fabric, neat and intensive circle suede or the clipping of formation on the blanket face.
3, be coated with at the blanket back side and scrape synthetic latex or polyester-class adhesive, and base fabric and synthetic tuft are glued into firm integral body.
4, postfinishing process comprises with the smooth blanket face of loop cutting machine, blanket face stamp, the blanket back of the body and pastes foamed plastics backing or gunny cloth backings such as butadiene-styrene rubber or Polyurethane, the fluffy and finishing blanket face etc. with steam.
The yarn of synthetic tuft generally adopts blended yarns such as terylene, polyamide fibre, polypropylene fibre, and expensive goods is used pure wool yarns; Base fabric uses the jute woven fabric in early days, most at present polypropylene fibre flat filament woven fabric, polyester filament woven fabric or supatex fabric of adopting.
The lint of carpet is implanted wool yarn to form looped pile by special tufting needle on base fabric; Cut off looped pile and form lint; Resin, sizing material (backing sizing material) set looped pile or lint are coated in the base fabric back side, prevent that fine hair is loose to come off and pilling, and can improve the DIMENSIONAL STABILITY of woollen blanket.At the carpet back side that scribbles glue, also can paste one deck foam-back again, the stickup second layer fabric at the carpet back side that also has is claimed the secondary backing, all has the function that increases tufted carpet elasticity and durability.Product is mainly as aisle, indoor floor pavement material.
Because existing synthetic tuft equipment is generally row's pin machinery, promptly adopt the needle-bar that a row is installed or arranges tufting needle more, each tufting needle is processed simultaneously.
Because tufting is thicker, so its density refractory is to increase.The tufted carpet that adopts above-mentioned synthetic tuft apparatus processing to come out is compared with hand-made carpet; Because the pattern on the carpet is made up of dot matrix; Therefore there are slack shortcoming in curve, oblique line, have a strong impact on the whole pattern visual effect, and because the color kind that can adopt is considerably less; Usually have only about 8 kinds, so the pattern color on the carpet is dull, pattern is lively inadequately, artistic expression is relatively poor.
In order to let the tufted carpet of machinery production can be near the level of hand-made carpet, the applicant adopts manipulator imitation true man action, handles the tufting rifle and processes.In order to let manipulator can control the work of tufting rifle; Need to have between manipulator and the tufting rifle one can be with the transmission of power of the driving mechanism that is positioned at manipulator transmission mechanism to the tufting rifle; The applicant has designed a kind of transmission mechanism; This transmission mechanism comprises manipulator running part and tufting rifle running part, and the manipulator running part is connected through a pair of connector that can cooperatively interact with tufting rifle running part.But; The tufting rifle was very strict with respect to the status requirement of manipulator when this transmission mechanism grasped the tufting rifle to manipulator; Otherwise manipulator can't be connected with a pair of connector between the tufting rifle; When but the grasping mechanism of existing machinery hand grasped the tufting rifle, the tufting rifle was difficult to be in accurate position, therefore caused manipulator can't be connected with a pair of connector between the tufting rifle.
