Abstract

The present invention relates to an adjusting mechanism of belt driving shafts of ribbon looms. Mainly, the adjusting mechanism is provided with a cylindrical bearing base. A plurality of concentric arc-shaped holes arranged on an adjusting plate which is convexly arranged on the outside of the bearing base. Both ends of an eccentric shaft hole arranged on the inner side of the bearing base are respectively provided with bearings. Therefore, transmission shafts can be penetrated into the bearings of the bearing base. The bearing base is arranged on a machine frame of a ribbon loom through the arc-shaped holes of the adjusting plate matched with screw bolts. When the screw bolts are released to rotate the bearing base, the transmission shafts arranged in the eccentric shaft holes can be shifted. In addition, the concentricity of the two bearings can be kept during of displacement so as to reach the effect of convenient adjustment and accurate control.

Description

Inkle loom belt drive shaft guiding mechanism

Technical field

The present invention relates to a kind of inkle loom belt drive shaft guiding mechanism, it is with the bearing block assembling two bearings of a tool eccentric pivot hole, and allow power transmission shaft wear wherein, when adjusting retainer, can adjust the relative position of two bearings simultaneously with respect to frame, and then the position of adjustment power transmission shaft, reach convenient and adjust and the effect of accurately controlling.

Background technology

Inkle loom normally provided the source of major impetus by a main motor, and these power resources is sent in the mechanism at each position of inkle loom via belt promptly when operating; Loom is based on the demand of drive characteristic as another, almost be all to adopt belt to transmit power, but well-known be that belt can't block into strips as chain when mounted, and then again its two ends are engaged after being mounted to the location; Belt inevitably can stretch because of tired in use for some time again, so operating personnel must in time adjust the relative position between two belt pulleys, to provide belt suitable tension force, and then guarantee the stability that power transmits, this promptly makes the distance between two relative belt pulleys must be designed to the structure of adjustable.

With a kind of power transmission shaft guiding mechanism that can see on the market at present as shown in Fig. 6～Fig. 8, the support plate 75 that it parallels in the 70 1 side settings of pedestal plate, on this pedestal plate 70 and support plate 75, be provided with the relative axis hole that runs through 71 and 76, around this

axis hole

71 and 76, be provided with the strip assembly hole 72 and 77 of parallel belts bearing of trend, and be provided with fixing threaded hole 73 (fixing threaded hole of relevant position does not give and illustrating on support plate 75) in pedestal plate 70 axis holes 71 1 side appropriate locations;

Be assembled with bearing block 80 at pedestal plate 70 respectively with the support plate 75 relative outsides, this bearing block 80 in the form of a ring, and with assembling screw 81 pass assembly hole 72 and 77 cooperate nuts 82 be assembled in pedestal plate 70 and support plate 75 relative outside, in these bearing block 80 center stack bearing 83 is housed, is provided with ejection face 84 in these bearing block 80 outer rims; With set bolt 86 fixed block 87 is assembled in fixing threaded hole 73 places in these bearing block 80 sides, simultaneously on fixed block 87 with the ejection face 84 of ejection bolt 88 ejection bearing blocks 80;

The power transmission shaft 90 that is assembled with belt pulley 92 then is assembled between pedestal plate 70 and the support plate 75, and makes the two ends of power transmission shaft 90

pass axis hole

71 and 76 and by bearing 83 supportings.

When operating personnel's desire moves power transmission shaft with adjustment belt degree of tightness, as Fig. 7, shown in Fig. 8, operating personnel can loosen assembling screw 81 and nut 82 earlier, rotate ejection bolt 88 then and force bearing block 80 displacements, in bearing block 80 displacements, assembling screw 81 can displacement in the strip assembly hole 72 and 77 of parallel belts bearing of trend, and by the 90 generation displacements of bearing 83 drive power transmission shafts, by the guiding mechanism shown in the figure as can be known, this guiding mechanism is by diaxon bearing 80 common supporting one power transmission shafts 90, that is move when adjusting carrying out power transmission shaft 90 positions, the bearing 83 of mobile both sides simultaneously, but operate the ejection displacement by different ejection bolts 88 respectively with the bearing block 80 in support plate 75 outsides owing to be arranged at pedestal plate 70, so when operating personnel adjust, extremely difficulty allows the bearing 83 of both sides be adjusted to concentric position, that is its deflection that when adjusting, allows power transmission shaft 90 produce slightly unavoidably, as long as being familiar with the personage of this technology all can understand, in case the deflection of minimum amplitude takes place in the belt pulley power transmission shaft, on-stream belt promptly can press to a side, and make a lateral edges of belt and belt pulley that abnormal friction takes place, and easily make belt be worn and reduce service life; Obvious existing this type of guiding mechanism time-consuming consumption worker when adjusting, and control the accuracy deficiency, the necessity that is improved is really arranged.

Summary of the invention

Main purpose of the present invention is to overcome the deficiencies in the prior art and defective, a kind of inkle loom belt drive shaft guiding mechanism is proposed, it mainly is that assembling is provided with a bearing block that is cartridge type on the frame of inkle loom, be provided with an eccentric pivot hole in this bearing block inboard, and be assembled with bearing respectively at the two ends of this eccentric pivot hole, power transmission shaft can be arranged in thus in the bearing in the bearing block, when the turning cylinder bearing, can make and wear the power transmission shaft that is assembled in the eccentric pivot hole and be shifted with respect to frame, and the concentricity that can keep two bearings in displacement reaches convenient and adjusts and the effect of accurately controlling.

For reaching above-mentioned purpose, the invention provides a kind of inkle loom belt drive shaft guiding mechanism, on the frame of inkle loom, be formed with a perforation, around this perforation, be formed with several screws; This guiding mechanism comprises: one is the bearing block of cartridge type, convexes with the adjustment plate in this bearing block outside, and this adjustment plate is provided with several concentric arcuate sockets, is provided with an eccentric pivot hole in the bearing block inboard in addition; Two bearings are assembled in the two ends of this bearing block eccentric pivot hole respectively; One power transmission shaft is arranged in the bearing in the bearing block; Several bolts are located in each arcuate socket of adjustment plate of bearing block respectively; Thus, bearing block can be combined in frame perforation place with bolt, this bolt passes the arcuate socket of adjusting plate and bearing block is assembled on the inkle loom frame, can make its eccentric pivot hole drive the relative frame displacement of power transmission shaft by the turning cylinder bearing sleeve, adjust the position of power transmission shaft with respect to frame, and can accurately adjust, and can allow the two bearings of supporting drive shaft remain on the absolute concentric position.
