Figure 11 is the cam box sterogram.
Referring to Fig. 1-4 shaded portion is the cam box and the corresponding transmission mechanism thereof of active type cam opening device, and shadow-free partly is the loom body.Cam box 29 is installed on 30 times outer hand hay cutters of the right frame wallboard of loom, and the shedding assembly is installed on 30 times inboards of right frame wallboard, and the hole that the shedding connecting rod passes right frame wallboard downside couples together the two, and 31 is oil feed pump.Structure for existing water jet looms, the loom motor can be moved to the afer bay upside, the hole that former motor is installed just in time is used to pass for connecting rod between cam box and the shedding arm, and this point is very important to existing water jet looms repacking the utility model cam opening device of having finalized the design.
Loom main shaft 1 drive main pulley 2 and belt 3 transmissions drive bevel gear again and pay 5 from belt wheel 4, and the camshaft 6 coaxial with bevel gear is provided with some to conjugate cam 7.During the camshaft rotation, the every pair of conjugate cam corresponding with it applying of transmission respectively is located at pair of cams rotor 9 on the fork 8, making fork is left and right swing of fulcrum and the 11 left and right swings of drive shedding connecting rod with its eccentric shaft 10, the shedding connecting rod swings by the pawl that connector 12 drives main shedding arm 13, another pawl of main shedding arm is around the upper and lower motion of its fulcrum, thus the opening montant 15 upper and lower motions that drive is connected with heald frame 14.One connecting rod 16 is set on main shedding arm, drives another from shedding arm 13 ' and opening montant 15 ' be synchronized with the movement.
Referring to Fig. 5, regulate the sliding position of connector 12 on main shedding arm 13, the adjustable openings amount, the opening amount that moves up reduces, and it is big to move down the opening quantitative change, on the main shedding arm 13 the scale reference is arranged, and after adjusting, is fastenedly connected the screw location on 12.Adjust heald frame height as need, can regulate two shedding arms 13 and 13 ' with opening montant 15 and 15 ' between the upper and lower shift position of connector 17 and 17 ' on the opening montant realize, after the position is determined, the usefulness fastening location of bolt (as Fig. 6).
The cam bit shape as shown in Figure 7, every cam is provided with round boss face 18, which is provided with connecting hole.Per two cams are a pair of conjugate cam, and are fixing by two hollow pins 19,20.Be stationary cam on camshaft, and according to different revolutions phase difference requirement when, design there are 3～5 bolts hole respectively, is 4 bolt hole 21-24 as Fig. 7.With some cam is assemblied on the camshaft as shown in Figure 8,8 pairs of cams are arranged among the figure, penetrate in the hole corresponding on the flange 26 of cam bit and camshaft 6 fastening with bolt 25.According to the requirement of fabric tissue, cam profile shape, conjugate cam logarithm and when on camshaft, settling between phase place etc., no longer narrate at this.
The utility model also is provided with waterproof and centralized lubrication structure in conjunction with the water jet looms handling characteristics.As shown in Figure 3,28 protect for waterproof and to put, and 27 is fuel feed pump, the lubricated pump 31 (Fig. 1) at regular time and quantity that also includes of fuel feed pump.Flowmeter, oil dripping box etc. do not mark among the figure.
Shedding assembly and frame connect the axle bed connecting mode that adopts shown in Fig. 9,10, the label 32 among its coupled position such as Fig. 3.Figure 11 arranges sterogram in the cam box, and wherein 7n represents n to conjugate cam, and the n on transmission n fork 8n is to cam follower 9n, n to fork transmission n to shedding connecting rod 9n ..., all drive station are hinged connected mode.
The utility model has the advantages that:
1. using this device can make loom speed improve 30% and price only has domestic multi-arm than dobbies 50% of machine, and dobbies grinds by the peg that nylon spare peg ejects in slip and then the generation harness motion Decrease very fast, thereby brought fabric defect that the unreliability of harness motion causes in this device almost Do not exist.
2. the crank connecting link plain loom can only be weaved the plain weave cloth, originally establishes as installing at plain loom The meter shedding motion then can weave multiple twill and satin weave fabric. The added value of fabric is improved greatly, Widen the scope of application of plain loom with littler cost, improved the economic benefit of enterprise.
3. all there are spring reset in multi-arm type opening and passive type cam opening on design principle.Numerous springs has consumed a large amount of merits in continuous operation.There is not this problem in this device, so power demand descends greatly.Because of this device is higher by 30% than the dobbies speed of a motor vehicle, this means that output exceeds 30% again.Because of the smooth working continuously for a long time of this device, the fault of Woven fabric is few again, and the rapid wear accessory uses few.Can weave twill, satin weave lining on the crank connecting link plain loom again if be contained in, improve value-added content of product.
4. owing to adopted the cam of high accuracy conjugation profile, fork rolls to regenerate by dedicated cam rotor applying conjugation profile and produces swing, and heald frame is done upper and lower motion according to the rule of setting (cam face).The lubricated synchronously cooling of the running of all friction of motion positions and body in the casing, design can long-term smooth working under 650 rev/mins of fast states still.To some places friction of motion point design and installations such as shedding positions full-automatic opposing formula refueling device, further assurance has been made in long-term stability operation.
5. but maximum ten heald frames of transmission of the utility model have satisfied the conventional requirement of Silk Industry fabric variety.
6. connecting of shedding assembly and frame wallboard, adopt axle bed formula (as Fig. 9), the shedding assembly can be rested on the axle bed easily, be convenient to install, adjust, overcome the difficulty that similar structures in the past adopts the positioning bolt hole mode to install.
