Abstract
The utility model provides an air cylinder type opening forming mechanism, and belongs to the technical field of textile manufacturing machines. The air cylinder type opening forming mechanism comprises lifting air cylinders, a cross beam and a heddle frame, wherein the heddle frame is arranged below the cross beam and is provided with warp holes horizontally arranged side by side; the lifting air cylinders are symmetrically arranged at the two ends of the cross beam, are fixed to a machine frame, and are connected to air paths through vertical air holes. The air paths are opened or closed to control a piston rod to stretch and contract. According to the air cylinder type opening forming mechanism, the cross beam and the heddle frame are controlled to move up and down through the air paths to finish opening forming work of weaving. Compared with a cam mechanism or a connecting rod mechanism, the air cylinder structure is simpler in structure, and can ensure that the size of a machine is smaller and assembling can be more conveniently carried out; force applied to the cross beam and the heddle frame by the air cylinder is elastic, and therefore the cross beam and the heddle frame can not be damaged easily when running into resistance.
Description
Technical field
The utility model belongs to technical field of textile machine, is specifically related to the air-cylinder type shedding mechanism of a kind of use on loom.
Background technology
Loom is through mainly comprising shedding mechanism, weft insertion device, beating-up mechanism, spooler, warp-feeding mechanism and frame, startup, braking, transmission mechanism etc.Wherein shedding mechanism can separate warp thread up and down according to fabric tissue, forms shed open, for wefting insertion.Concrete opening principle is, by the heald frame of two upper and lower crisscross motions, to drive respectively two groups of staggered warps, make to produce opening between these two groups of warps, then by weft insertion device, parallel is passed from described opening, then by beating-up mechanism, parallel is interrupted, parallel is compressed simultaneously; Described staggered heald frame counter motion intersects parallel fixing on warp, and again warp thread is separated up and down, forms shed open, then repeats the wefting insertion beating motion, and this action gone round and begun again will form silk thread the longitude and latitude structure and be made into cloth.Last spooler is batched the cloth woven.
Moving up and down of heald frame realizes by cam structure or linkage usually, needs to be equipped with drive mechanism or special power set, makes like this total comparatively complicated, and the volume of machinery is larger, and inconvenience is installed, and cost is also higher.And cam structure or linkage motion the time torsion fix, when framework meets with obstruction like this, still can move by force, easily damage.
Summary of the invention
For above problem, the utility model provides a kind of air-cylinder type shedding mechanism that uses cylinder to control the heald frame lifting.
The utility model solves the technical scheme that its technical problem adopts: this air-cylinder type shedding mechanism comprises lift cylinder, crossbeam, heald frame; Described heald frame is assemblied in described crossbeam below, is designed with horizontal direction warp hole side by side on heald frame; Described lift cylinder symmetry is loaded on the two ends of described crossbeam, and described lift cylinder and frame fix, and described lift cylinder is by upper and lower gas port access gas circuit.Carry out the flexible of control piston bar by the break-make of gas circuit.
As preferably, the inboard of described lift cylinder is equipped with vertical slideway, is designed with the vertical chute of twice on described vertical slideway.Described crossbeam passes in chute.
The beneficial effects of the utility model are: this air-cylinder type shedding mechanism uses on loom, and the warp hole of the warp on cloth from heald frame passed, and this mechanism controls described crossbeam by gas circuit and moves up and down together with heald frame, completes the mouth-opening action of weaving cotton cloth; With respect to cam mechanism or linkage, air cylinder structure is simpler, can be so that the volume of machinery be less, assemble conveniently, and and the power that cylinder applies crossbeam and heald frame is flexible, not fragile when crossbeam and heald frame meet obstructions.
The accompanying drawing explanation
Fig. 1 is the structural representation of this air-cylinder type shedding mechanism.
In figure: 1, lift cylinder; 2, crossbeam; 3, heald frame; 31, warp hole; 4, vertical slideway.
The specific embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1, this air-cylinder type shedding mechanism comprises lift cylinder 1, crossbeam 2, heald frame 3; Described heald frame 3 is assemblied in described crossbeam 2 belows, is designed with horizontal direction warp hole 31 side by side on heald frame 3; Described lift cylinder 1 symmetry is loaded on the two ends of described crossbeam 2, and described lift cylinder 1 fixes with frame, and described lift cylinder 1 is by upper and lower gas port access gas circuit.Control the flexible of lift cylinder 1 upper piston rod by the break-make of gas circuit.
This air-cylinder type shedding mechanism uses on loom, and described crossbeam 2 respectively needs two, two heald frame 3 in tandems with heald frame 3; The warp hole 31 of warp on cloth from heald frame 3 passed, and this mechanism controls described crossbeam 2 by gas circuit and moves up and down together with heald frame 3, and former and later two heald frames 3 interlock and move up and down, thereby complete the mouth-opening action of weaving cotton cloth.With respect to cam mechanism or linkage, air cylinder structure is simpler, can be so that the volume of machinery be less, assemble conveniently, and and the power that 1 pair of crossbeam 2 of cylinder and heald frame 3 apply is flexible, not fragile when crossbeam 2 and heald frame 3 meet obstructions.
The inboard of described lift cylinder 1 is equipped with vertical slideway 4, on described vertical slideway 4, is designed with the vertical chute of twice.Described crossbeam 2 passes in chute, along slideway, moves up and down.Vertically the design of slideway 4 can be so that crossbeam 2 and heald frame 3 move up and down more steady, and be designed with the vertical slideway of twice on each vertical slideway 4, the vertical slideway 4 of every like this cover can assemble two crossbeams 2 simultaneously, not only can save material, also can be so that structure is compacter.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
