Description
Technical field
The utility model relates to manipulator, specifically refers to the rotating machine arm of the storage tank cleaning line being used for polyurethane coating.
Background technology
Polyurethane water-proof paint is by the performed polymer containing NCO through polyaddition reaction such as isocyanates, polyethers, be equipped with catalyst, anhydrous auxiliary agent, anhydrous filler, solvent etc., through the mono-composition poyurethane water-proof paint that the operations such as mixing are processed into.Such coating is reaction-curable (moisture-curable) coating, has the features such as intensity is high, percentage elongation is large, water resistance is good, to basic unit distortion adaptable.It is the moisture contact Post RDBMS in air, forms firm tough and tensile without the anti-film of seam entirety of one deck in substrate surface.And the thermo oxidative stability as raw materials such as polyethers is insuperior, the easy chain rupture of polyethers under the effect of oxidation, generates low molecular carbonyl and carbonyls.Therefore the raw material of polyurethane coating and the storage tank of reactant need adopt the mode of dry de-oxygen and filling nitrogen to prevent material oxidized.Polyurethane coating often needs to use storage tank in process of production, comprises the storage tank of raw material.Angle for cost can not use disposable or single use storage tank to produce, and therefore in process of production, material uses or do not use after rear storage tank often cleans and repeatedly uses.Existing fill nitrogen environment replace under traditional natural condition to storage tank clean guarantee storage tank fill nitrogen state, and adopt the mode of filling rotary-cleaning to carry out the waste of saving water resource, and adopt manipulator to reach rotary-cleaning, but existing robot manipulator structure is complicated, cost is high, cannot be applicable to middle-size and small-size polyurethane coating production company.Therefore, design a structure for above-mentioned prior art Problems existing simple, being convenient to storage tank cleaning can water-saving cleaning device be also the object that the utility model is studied.
Utility model content
For above-mentioned prior art Problems existing, the utility model is the rotating machine arm of the storage tank cleaning line being provided for polyurethane coating, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is:
For the rotating machine arm of the storage tank cleaning line of polyurethane coating, comprise and promote rotating mechanism and clamp, described clamp comprises pedestal, the front end of described pedestal is hinged with symmetrically arranged left jig arm and right jig arm, described pedestal is provided with extension spring between described left jig arm and right jig arm, and the described left jig arm medial surface relative with right jig arm is provided with the cushion of wave structure; The rear end of described pedestal is connected with rotating shaft, and one end that described rotating shaft does not connect pedestal is provided with gear, and the position of described rotating shaft between corresponding gear and pedestal is provided with fixed muffle by least two bearing holder (housing, cover)s; Described promotion rotating mechanism comprises promotion cylinder, and the piston rod of described promotion cylinder is connected with fixed bar, and the bottom of described fixed bar is provided with tooth bar; Described clamp is meshed by gear and tooth bar and is arranged on the below of promotion rotating mechanism.
Described cushion is rubber structure.
Advantage of the present utility model:
The utility model structure is simple, and it is convenient to install, and can be arranged on the cleaning line of polyurethane coating production storage tank; By the cooperation of rack and pinion, then the installation of bearing of arranging in pairs or groups is arranged, and can guarantee the turning effort of manipulator, and then drives the storage tank of filling with liquid to carry out rotary-cleaning, improves cleaning performance; The setting of cushion can strengthen the frictional force between clamp and storage tank, guarantees the fixing of gripping, ensures the operation of spinning movement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic side view of the present utility model.
Detailed description of the invention
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to Fig. 1-2, for the rotating machine arm of the storage tank cleaning line of polyurethane coating, comprise and promote rotating mechanism and clamp 1, described clamp comprises pedestal 11, the front end of described pedestal 11 is hinged with symmetrically arranged left jig arm 12 and right jig arm 13, described pedestal 11 is provided with extension spring (mark) between described left jig arm 12 and right jig arm 13, and described left jig arm 12 medial surface relative with right jig arm 13 is provided with the cushion 14 of wave structure, and described cushion 14 is rubber structure; The rear end of described pedestal 11 is connected with rotating shaft 2, and one end that described rotating shaft 2 does not connect pedestal 11 is provided with gear 3, and the position of described rotating shaft 2 between corresponding gear 3 and pedestal 11 is arranged with fixed muffle 5 by least two bearings 4; Described promotion rotating mechanism comprises promotion cylinder 6, and described promotion cylinder 6 carries out stretching out the flip-flop movement that reset repeating motion reaches clamp 1, and the piston rod of described promotion cylinder 6 is connected with fixed bar 7, and the bottom of described fixed bar 7 is provided with tooth bar; Described clamp 1 is meshed by gear 3 and tooth bar and is arranged on the below of promotion rotating mechanism.
After left jig arm 12 and right jig arm 13 clamp storage tank, promote cylinder 6 and stretch out the motion of band carry-over bar, by the engagement of gear 3 and tooth bar, make gear 3 drive clamp 1 and rotating shaft to be rotated, thus carry out the rotary-cleaning of the storage tank after filling with liquid.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
