Abstract
The invention relates to a clamping valve for an upper auxiliary machine. The clamping valve is used for conveying white carbon black in the natural rubber production process and shutting down conveyance. Top ends of a left brake arm and a right brake arm are connected to two sides of the top of a support frame respectively, a left clamping roller is fixed at the bottom end of the left brake arm, and two right clamping rollers are fixed at the bottom end of the right brake arm. Transmission rods are driven to extend and retract through cylinders arranged in middles of the left side and the right side of the support frame, and the transmission rods push the left brake arm and the right brake arm to rotate counterclockwise and clockwise respectively. When the transmission rods extend, the left clamping roller and the right clamping rollers squeeze a conveying rubber ring simultaneously till the left clamping roller is in line contact with the two right clamping rollers at the same time by being separated through the conveying rubber ring, and the conveying rubber ring is closed; when the transmission rods retract, the conveying rubber ring is smooth, and accordingly normal conveying can be guaranteed.
Description
Technical field
The invention belongs to a kind of for control white carbon and isolating agent in natural rubber production process conveying time pinch valve, be specifically related to a kind of upper subsidiary engine pinch valve.
Background technique
White carbon is precipitated silica, aerosil, superfine silicon dioxide gel and aerogel mix; for fine powder shape; white carbon has superpower adhesive force, tear-proof and heat-resistant aging quality, and after rubber grain mixing, banburying can obtain high-quality rubber product.Natural rubber is pulverized and banburying time the combined amount of white carbon is controlled there is strict proportion requirement, use metallic material to carry out carrying and switch control rule in traditional processing technology process, because of white carbon, this is difficult to accomplish accurately to control and close down in time as fine powder.
For solving the problem, the present invention can precise delivery and the upper subsidiary engine pinch valve of closing down in time for a kind of baihuixiong of carrying.
Summary of the invention
Technological scheme of the present invention is:
In one, subsidiary engine pinch valve comprises: outer support frame, be rotationally connected plate, cylinder, drive link, dunnage, left brake arm, right brake arm, left clamping roller, right clamping roller, conveying rubber ring, pressing plate, support annulus and adpting flange, described outer support frame profile is that square body is each side provided with and is rotationally connected plate, described being rotationally connected on plate is fixed with cylinder, described outer support frame top is each side provided with two relative dunnages, two dunnages being arranged on left side connect left brake arm top, described left brake arm tail end installs a left clamping roller, two dunnages being arranged on right side connect right brake arm top, described right brake arm tail end arranges two right clamping rollers, be arranged on supporting frame left hand cylinder to be connected with left brake arm by drive link, be arranged on supporting frame right cylinder to be connected with right brake arm by drive link, the bad shape pressing plate of circumference is provided with in the middle of the dunnage of four, described outer support frame top, described conveying rubber ring upper end is fixed on supporting frame top by pressing plate, described conveying rubber ring bottom is provided with support annulus.
The present invention improves further and is: described drive link is stretched by the adjustment of cylinder air pressure, and when described drive link stretches out, left brake arm and right brake arm are that the center of circle turns counterclockwise and rotates clockwise respectively with dunnage.
The present invention improves further and is: described left clamping roller lateral diameters is 1.5 times of right clamping roller, ensures that left clamping roller can contact to clamp conveying rubber ring with right clamping roller simultaneously simultaneously realize closing down.
The present invention improves further and is: described drive link is when retracting completely, described left clamping roller and right clamping roller and conveying rubber ring contactless, now conveying rubber ring is that unimpeded state can normal conveying, when described drive link stretches out completely, left clamping roller and two right clamping rollers extrude conveying rubber ring simultaneously and form linear contact lay, and time a little, conveying rubber ring is closed condition by the extruding of a left clamping roller and two right clamping rollers.
The present invention improves further and is: described outer support frame is made up of square sheet material, and top is covered with steel plate, and described outer support frame top is provided with circular material feeding mouth, and place is provided with pressing plate.
The present invention improves further and is: described conveying rubber ring connects miscellaneous equipment by adpting flange.
Accompanying drawing explanation
Fig. 1 is side view of the present invention.
Fig. 2 is plan view of the present invention.
Wherein: 1-outer support frame, 2-is rotationally connected plate, 3-cylinder, 4-drive link, 5-dunnage, the left brake arm of 6-, the right brake arm of 7-, the left clamping roller of 8-, the right clamping roller of 9-, 10-conveying rubber ring, 11-pressing plate, 12-supports annulus, 13-adpting flange.
Embodiment
The following detailed description of the specific embodiment of the present invention:
Subsidiary engine pinch valve in one, as shown in Figure 1, outer support frame 1 is formed by square sheet material, top is covered with steel plate, supporting frame 1 top is provided with circular material feeding mouth, conveying rubber ring 10 top is fixed on supporting frame 1 top by pressing plate 11, is fixed into circle and is connected with miscellaneous equipment by adpting flange 13 bottom conveying rubber ring 10 by support circumferential ring 12.
Both sides, supporting frame 1 top are respectively provided with two dunnages 5 mutually, two dunnages 5 in left side connect left brake arm 6 top, left brake arm 6 bottom is fixed with left clamping roller 8, two dunnages 5 in right side connect right brake arm 7 top, right brake arm 7 bottom is fixed with two right clamping rollers 9, the lateral diameters of left clamping roller 8 is 1.5 times of right clamping roller 9 lateral diameters, supporting frame 1 left and right sides intermediate portion is respectively provided with and is rotationally connected plate 2, the cylinder 3 that the left and right sides is arranged is fixed on supporting frame 1 by being rotationally connected plate 2, and be connected with right brake arm 7 with left brake arm 6 respectively by drive link 4, drive link 4 is stretched by the adjustment of cylinder 3 air pressure, when drive link 4 stretches out, left brake arm 6 and right brake arm 7 to turn counterclockwise for the center of circle with dunnage 5 respectively and rotate clockwise, when drive link 4 is retracted completely, left clamping roller 8 and right clamping roller 9 contactless with conveying rubber ring 10, now conveying rubber ring 10 be in unimpeded state can normal conveying, when drive link 4 stretches out completely, left clamping roller 8 and two right clamping rollers 9 extrude conveying rubber ring 10 simultaneously, until left clamping roller 8 forms linear contact lay with two right clamping rollers 9 across conveying rubber ring 10 simultaneously, now conveying rubber ring 10 is the state of closing down, conveying cannot be carried out, because the elasticity of rubber itself and the double-deck linear contact lay extruding of three niproll cylinder formation can avoid fine powder shape white carbon to continue lower leakage completely.
