Abstract
The utility model relates to a friction roller clamping device for producing liquid crystal, which belongs to liquid crystal producing equipment. The friction roller clamping device for producing liquid crystal is composed of a left part and a right part. The left part comprises a slide bearing seat 5 which is installed in a supporting sleeve on a left bracket 4. A driven shaft 6 is installed in the slide bearing seat 5 by a bearing, and the right end of the driven shaft is provided with a clamping head 11. A roller doffing wrench 12 is fixed on the top of the slide bearing seat 5 by a slide pin 13, and the end part of the roller doffing wrench 12 is fixed on the left bracket by a rotary pin 3. Tension springs 2 are respectively arranged on two sides of the slide bearing seat 5, one end of each of the tension springs 2 is fixed on a press plate 1, and the other end of each of the tension springs 2 is fixed on the left bracket 4. The right part of the friction roller clamping device for producing liquid crystal has the structure that a rotary shaft 10 is installed on a right machine rack 8 by a bearing, a belt pulley 9 is fixed on one end of the rotary shaft 10, the other end of the rotary shaft 10 is provided with a clamping head 11, and a friction roller 7 is clamped between two clamping heads. Compared with the existing friction roller clamping device, the friction roller clamping device for producing liquid crystal has the advantages of simple structure, convenient operation, easy processing, and low cost.
Description
One, technical field
The utility model belongs to the liquid crystal production equipment, specifically the friction roller clamping device of rubbing machine.
Two, background technology
In the liquid crystal technological process of production, friction is one gordian technique of operation before being in.For coming realization information, the optical anisotropy that utilizes liquid crystal molecule shows, liquid crystal molecule is designed to various forms of pattern of rows and columns, form the potential trough of a constraint liquid crystal molecular orientation, concrete grammar is to liquid crystal cell substrate inside surface rubbing, forms the trickle groove mark of direction unanimity.Friction roller is positioned on the support of rubbing machine, and the albatross on friction roller surface is a consumable accessory, need frequently to change, and existing friction roller clamping device complex structure, the machining precision height is so manufacturing cost is higher.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, the friction roller clamping device of low production cost.
The utility model is achieved in that liquid crystal friction roller clamping device is made up of left and right two parts.Left half comprises: in the supporting sleeve on left socle 4, plain bearing housing 5 is installed, in plain bearing housing 5, the right-hand member of driven shaft is a clamping head 11 to driven shaft 6 by Bearing Installation; Roll release spanner 12 is fixed on the top of plain bearing housing 5 by sliding pin 13, and roll release spanner 12 ends 3 are fixed on the left socle by shipping and reselling on another market; Both sides at plain bearing housing 5 are equipped with extension spring 2 respectively, and an end of extension spring 2 is fixed on the pressing plate 1, and the other end is fixed on the left socle 4; The right half structure of this device is: by Bearing Installation rotating shaft 10 is arranged on the right frame 8, an end of rotating shaft 10 is fixed with belt pulley 9, and the other end is a clamping head 11, and the external diameter of clamping head 11 is the conical surface, and tapering is 1:5; Clamping has friction roller 7 between two clamping heads.
Compare with existing friction roller clamping device, the beneficial effects of the utility model are: simple in structure, easy to operate, easily processing is with low cost.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, pressing plate, 2, extension spring, 3, ship and resell on another market, 4, left socle, 5, plain bearing housing, 6, driven shaft, 7, friction roller, 8, right support, 9, belt pulley, 10, rotating shaft, 11, clamping head, 12, spanner, 13, removable pin.
Five, embodiment
When needs are changed friction roller 7, pull roll release spanner 12 clockwise, the roll release spanner 3 is a fulcrum to ship and resell on another market, drive plain bearing housing 5 to left by sliding pin 13, the driven shaft 6 that is installed in the plain bearing housing 5 is driven simultaneously to left, two extension springs 2 are elongated, and at this moment clamping head 11 moves to left, and friction roller 7 released clampings are taken off.When loosening roll release spanner 12, under the rebound effect of extension spring 2, with plain bearing housing 5 together with driven shaft 6 to right translation, clamping device resets.
The liquid crystal substrate is positioned at the below of friction roller 7, and friction roller is held in the time of need turning round, and starts running part, and odontoid belt drive pulley 9 rotates, and drives rotating shaft 10 gearing friction rollers 7 and rotates, and carries out directional process by will the rub inner surface film of substrate of technological requirement.
