Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-6, a roller mechanism of a sand mixer for improving the sand mixing effect comprises a tank body 1, a rotating table 2 is fixedly installed on the bottom surface of the tank body 1, a fixed main shaft 3 is arranged in the middle of the tank body 1, the tank body 1 and the fixed main shaft 3 move relatively, the fixed main shaft 3 penetrates through the tank body 1 and the rotating table 2, rotating shafts 4 are fixedly installed on two sides of the fixed main shaft 3, a roller 5 is movably installed at the other end of each rotating shaft 4, arc-shaped plates 6 are hinged on the surfaces of the roller 5 at equal intervals, the outer surfaces of the arc-shaped plates 6 are rough surfaces, the outer surfaces of the arc-shaped plates 6 are arranged in a curved surface mode, when the arc-shaped plates 6 roll materials, the force applied to the materials on the same plate width line is the same, the rolling force applied to the materials is the same, the materials are uniformly mixed, the other ends of the arc-shaped plates 6 are connected with the roller 5 through elastic members 7, sliding plates 8 are fixedly installed on the inner surfaces of the arc-shaped plates 6, the sliding plate 8 is slidably mounted in the sliding groove 9, the sliding groove 9 is arranged on the grinding wheel 5, when the motor drives the tank body 1 to rotate, the material rotates along with the rotation and contacts the arc-shaped plate 6, and further the grinding wheel 5 is stressed to rotate, so that the material is ground and kneaded to be mixed, when the arc-shaped plate 6 on the grinding wheel 5 does not reach the grinding area, the arc-shaped plate 6 is pushed by the elastic element 7 to open, when the open arc-shaped plate 6 contacts the material layer, the sliding friction is generated between the open arc-shaped plate 6 and the material layer surface, so that the arc-shaped plate 6 can drive the surface material to enter the grinding area, the grinding amount of the material by the grinding wheel at a time is increased, the sand mixing efficiency is improved, in the process, the elastic element 7 extrudes the arc-shaped plate 6, the sliding friction force of the arc-shaped plate 6 on the material is increased, the material carrying amount of the arc-shaped plate 6 is increased, the sand mixing efficiency is improved, then the material enters the grinding area, and the material at the moment is not only applied by the grinding wheel 5, still receive the power of elastic component 7, thereby increase the bed of material atress, improve the mulling effect, and simultaneously, when the bed of material thickness in the nip is inhomogeneous, because the setting of elastic component 7, make arc 6 can be according to bed of material thickness automatically regulated roll pressure, and then guarantee the homogeneity of mulling, improve the mulling effect, and finally, leave the in-process in the nip when arc 6, the extrusion force that the rolling wheel 5 and material layer applied to arc 6 reduces gradually, and then make the elasticity of elastic component 7 be greater than above-mentioned power gradually, make arc 6 open, at open in-process, arc 6 is deep in the bed of material, and will compress tightly dial the pine, throw, make the bottom material appear on the bed of material surface, and then make the material misce, improve the mulling effect.
Wherein, the rolling area mentioned above refers to the contact area of the arc-shaped plate 6 below the rolling wheel 5 and the inner wall of the tank 1, that is, when the rolling wheel 5 is arranged, the arc-shaped plate 6 below the rolling wheel can be abutted and contacted with the inner wall of the tank 1.
Wherein, slide 8 can block sand material and get into the position between arc 6 and the grinding roller 5, avoids sand material to influence this device and moves smoothly.
The use method (working principle) of the invention is as follows:
when the material rolling machine works, firstly, the motor drives the rotating table 2 to rotate, so that the tank body 1 rotates, then materials are placed into the tank body 1, the materials are driven to rotate by the tank body 1, in the rotating process, the materials contact and push the arc-shaped plate 6, so that the rolling wheel 5 rotates, when the arc-shaped plate 6 does not reach the rolling area, the arc-shaped plate 6 is always under the elastic force of the elastic piece 7 and is in an open state, when the open arc-shaped plate 6 contacts the materials, the materials on the surface of a material layer can be carried into the rolling area, when the rolling wheel 5 continues to rotate, the arc-shaped plate 6 can be under the force exerted by the rolling wheel 5 and the material layer, so that the arc-shaped plate is changed into a closed state, meanwhile, the elastic piece 7 is compressed, then, the materials entering the rolling area are under the force exerted by the rolling wheel 5 and the elastic piece 7, so that the materials are rolled and mixed, meanwhile, when the materials with different thicknesses are rolled, the elastic piece 7 can automatically adjust the applied force according to the thickness of the material layer, make the bed of material atress even, when the grinding wheel 5 continues to rotate, make the arc 6 leave the zone of rolling, the arc 6 receives the elasticity of elastic component 7, and becomes to open by closed gradually, and at this in-process, arc 6 deepening the bed of material to the material that will compress tightly is dialled loose, is thrown up, makes the bottom material appear in the bed of material surface, and this is a duty cycle.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
