Description

Recurrent weft-depressing type power-driven mat-weaving machine

The present invention belongs to a kind of automatic machinery that weaves a seat.It is a latitude with the seat grass, is through weaving the different bed seat of various widths with hemp twine or nylon yarn.

The recurrent weft-depressing type power-driven mat-weaving machine that China's patent application 87211903.3 proposes has first been done bigger simplification and improvement to original mat-weaving machine.Basically be practicable.But it drives fixed gear by sliding rack in power transmission member.This collocation is stable inadequately, can not guarantee the abundant careless time of sending; In minute careless parts, error is many; In the lease making parts.Pulley on the η shape draw runner has rigid shock to the comb reed.And it is easy to wear; In drawing the limit parts, singly draw the limit and await changing into double edge-drawing.Owing to, just caused the recurrent weft-depressing mat-weaving machine on performance, can't reach stable and perfect on the whole in the suspicion that above each side still has some deficits.

Purpose of the present invention, be from overcoming above various defective, several new devices are provided, improve power transmission member, divide careless parts, lease making parts and draw the limit parts, thereby guarantee that on the whole the recurrent weft-depressing loom reaches perfection and stablize, bring into play its potential economic benefit to greatest extent.

The object of the present invention is achieved like this:

1, in power transmission member, occuping frame center, the place ahead has crank to be connected with it to comb the central gear (8) of reed (7) (below be referred to as central gear) and change into by sector (1) and promoting in order to promote T-shaped.The tooth bar of cancellation central gear both sides.Shown in Figure 1.Sector (1) unilateral deflection once.Drive central gear (8) and rotate a week.Thereby crank (2) drives comb reed (7) and presses latitude once.Can stop a moment slightly because sector (1) deflects to the limit at every turn, this has just guaranteed the abundant careless time of sending.

The kind of drive that sector (1) promotes central gear (8) also can change into by gear promotion central gear, and these two kinds of kinds of drive are the same on the function that realizes the pressure latitude.Different is: after sector promotion central gear whenever circles, all do reverse rotation.And the gear driven central gear is only done unidirectional rotation.

2, in minute careless parts, the present invention has done to simplify to the grass door of existing mat-weaving machine.Shown in Figure 2, a careless Men Yousan critical piece: with the O point is the whole careless arm (17) of fulcrum; With O ₁Point is got careless arm (15) for fulcrum; With O ₂Point takes off careless arm (14) for fulcrum, does once to promote up and down at the A end, and whole careless arm (17) just around the reciprocal deflection of fulcrum O once.The reciprocating motion of this whole careless arm has three functions: the little axle of ordering at B drives inside and outside whole careless plate (11) (13) lifting, realizes whole grass; Roller drive at the C end is got careless arm (15) around O ₁The reciprocal deflection of point realizes getting grass (10); Take off careless arm (14) in the roller drive of axle (16) and take off grass, and defeated grass is between two rubber tires from careless pin.Like this, as long as apply the motive force that once comes and goes, just can realize once dividing grass at the A point.

3, in the lease making parts, adopt the careless road reed of E tee section.As shown in Figure 3, the distance between the lease making groove that E shape grass road is vertical therewith equals (or being slightly larger than) two times of warps (18) spacing.The careless road reed of this shape also is a spreader simultaneously, and it just can respectively be pushed warp forward one when embedding between the warp row.Realizing lease making, more than is the shape of careless road reed.

The careless road reed of this shape all will be made first power to opposite horizontal displacement finishing after lease making send grass each time, and shift length approximates one through distance between centers of tracks, and this lateral displacement that replaces is to finish in the process of T-shaped comb reed frame (7) lifting.Central gear (8) drives the mechanism of T-shaped comb reed frame (7) lifting, as 87211903.3 patent first please as described in.The present invention has increased by two contents to this mechanism: center roller (4), and it is fixed on the frame center; Center rocker arm (6), its fulcrum (5) are positioned at the top, center of T-shaped comb reed frame (7), and height is corresponding with center roller (4).Showed that from Fig. 1 (A) to Fig. 1 (D) the comb reed finishes whole traverses of a lateral displacement.

Shown in Fig. 1 (A), the crank (2) that is connected with central gear (8) is pushed into the extreme higher position with careless road reed (9), be the level of state, this moment fulcrum (5), roller (4), the comb reed center slideway (3), crank (2), the center of circle of central gear (8) all is on the same vertical line, and center rocker arm (6) is squeezed partially by center roller (4), drives careless road reed (9) and has made lateral displacement.Treat lease making, send grass to finish.Central gear (8) beginning backward rotation, when going to the position of Fig. 1 (B), center roller (4) has lost the power of squeezing partially to center rocker arm (6); When going to the position of Fig. 1 (C), fulcrum (5) drives center rocker arm (6) around the opposite side that has arrived center roller (4); When center gear (8) goes to 360 degree, during as the position of Fig. 1 (D), the crowded partially of center roller (4) reaches capacity, and so far, center rocker arm (6) has driven careless road reed (9) and realized a lateral shift through distance between centers of tracks.Central gear (8) reverse rotation once more just can make careless road reed that reverse horizontal displacement takes place, and is returned to the state of Fig. 1 (A), so moves in circles.

4, double edge-drawing of the present invention is to be colluded with one and drawn limit fork and cooperate and finish by the limit of drawing of a rotation.Shown in Figure 4 is to draw limit mechanism vertical view, and diagram is drawn the right that the limit occurs in mat-weaving machine.Fig. 4 (A) expression, the latitude grass (22) of waiting to draw the limit have been fallen and have been drawn the limit and collude (21) the place ahead; Shown in Fig. 4 (B).Draw the limit and collude (21) axle center O around oneself ₃Rotate.Seize on both sides by the arms latitude grass (22) to the inside around; Shown in Fig. 4 (C), draw the limit and collude (21) and seize latitude grass (22) on both sides by the arms, and continue to go to the limit by between the E, F warp; Shown in Fig. 4 (D), draw limit fork (23) terminal yoke of latitude grass (22) is gone between G, the F warp, draw limit fork (23) then and withdraw from, draw the limit and collude (21) and produce, so far finish double edge-drawing one time.

The recurrent weft-depressing mat-weaving machine that proposes first in the present invention and 87211903.3 patent applications is compared, and has tangible good effect, and modern division is as follows:

1, in transmission of power, the central gear of original recurrent weft-depressing mat-weaving machine (8) is promoted by tooth bar, and the tooth bar of slip need have a plurality of pulleys to seize on both sides by the arms, and motion is unstable; The present changes into by sector or gear and promoting, because the fixing center of circle has been arranged, need not a plurality of pulleys and seizes on both sides by the arms, has both simplified structure, makes motion stabilization again, is convenient to guarantee the abundant careless time of sending again.

2, on the careless road reed of existing mat-weaving machine, the lease making separation perpendicular with E shape section is to equal one through distance between centers of tracks.Among the present invention, the spacing of lease making groove be two times through distance between centers of tracks, also that is to say that the total number of lease making groove has reduced half, this has reduced half with regard to making lease making groove corner angle to the resistance that the latitude grass advances.

Beat was finished in the middle part of the lateral shift of careless road reed before lease making of original recurrent weft-depressing mat-weaving machine promoted by the interior pulley on the η shape draw runner, pulley and beat have rigid shock in contacting meeting, and it is easy to wear, the present changes into by center rocker arm (6) alternately around the both sides to center roller (4), has then eliminated above drawback.

3, the grass door of original recurrent weft-depressing mat-weaving machine divides grass to make mistakes (promptly divide grass above one or do not have one) more.According to experiment, fault rate surpasses 3%; The modern drive by whole careless arm (17) got careless arm (15) and taken off careless arm (14), and according to experiment, the fault rate of getting grass is reduced to below 0.5%.

4, in the existing mat-weaving machine, generally adopt and singly draw the limit.The superior point of double edge-drawing provided by the present invention is: draw limit degree neat, attractive in appearance and knit seat technology above best craft; The double edge-drawing seat is more durable in use; The double edge-drawing seat caters to consumer's hobby, psychology and custom; Compare with the described double edge-drawing mechanism of effective 88202843 patent applications, the present invention only finishes double edge-drawing with the advance and retreat of colluding (21) and drawing limit fork (23) in the limit of drawing of rotation, need not to draw the lateral displacement that collude on the limit, structurally is a simplification greatly.
