Compared with prior art, the invention has the beneficial effects as follows: through drum assembly is set, reduced the waste of the spray material of workpiece in the blasting treatment process effectively in sand-blasting machine, reduced the production cost of enterprise.
Description of drawings
Fig. 1 is applied to the structural representation in the sand-blasting machine for a kind of drum assembly of the present invention;
Fig. 2 is the structural representation of a kind of drum assembly shown in Fig. 1;
Fig. 3 is that S among Fig. 2 is to view.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings the present invention is elaborated; But should be noted that; These embodiments are not limitation of the present invention; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Join shown in Figure 1ly, Fig. 1 is applied to the structural representation in the sand-blasting machine for a kind of drum assembly of the present invention.In this embodiment, sand-blasting machine 200 comprises at least: installing rack 3, and the outer cover 1 that is arranged on installing rack 3 tops, the bottom of this outer cover 1 are provided with taper spray material accepting groove 5; Be arranged on the whirlwind tube 2 at outer cover 1 top; The circulation canal 4 that connects this taper spray material accepting groove 5 and whirlwind tube 2.This circulation canal 4 is positioned at the outside of said outer cover 1, and is processed by elastomeric material.Concrete, a side of this outer cover 1 also is provided with a door-plate 7.
In conjunction with Fig. 2 and shown in Figure 3, in this embodiment, this sand-blasting machine 200 also comprises a drum assembly 100, and the spray material that is used for sand-blasting machine 200 reclaims, and it comprises: main shaft 10 and the connecting plate 11 that links to each other with this main shaft 10; From radially extended vertically disposed four supports 20 each other of this connecting plate 11; Housing 30, it is octagonal lantern shape structure, and is provided with an opening 301 in the side away from this connecting plate 11; This housing 30 is by 20 fixings of support; At least one the first side wall face 302 of this housing 30 is provided with some through holes of evenly arranging 312; Motor 40, it links to each other with this main shaft 10, moves pivotally along the axis 101 of main shaft 10 in order to drive this housing 30.
In this embodiment, this motor 40 drives this main shaft 10 through key 102, and main shaft 10 drives housing 30 through connecting plate 11 and support 20 and does rotation at a high speed.Concrete, this connecting plate 11 and support 20 are an overall structure.The motor 40 of this drum assembly 100 reliably is retained on the sand-blasting machine 200 through a fixed mount 6.More specifically, this fixed mount 6 is through welding and installing rack 3 and outer cover 1 reliable fixing.In this embodiment, this fixed mount 6 is the triangle weldment.
Further, the end of this support 20 is provided with a bending part 201.Can easily housing 30 be connected on the support 20 through this bending part 201.In this embodiment, this through hole 312 is circular, and diameter is 1 ~ 2mm, and is preferably 1mm.Certainly this through hole 312 also can be ellipse or other shapes.More specifically, these through hole 312 rectangular array arrangements.This support 20 is at least partly accommodated second side wall surface 303 of this housing 30.This first side wall face 302 and second side wall surface 303 are intervally arranged.This motor 40 is an ac motor.The axis 101 of this main shaft 10 is 30 degree with the angle of horizontal plane.
In this embodiment, when workpiece (not shown) blasting treatment, open the door-plate 7 on the outer cover 1, workpiece is placed on the inside of housing 30 through opening 301, and will sprays the surface that material sprays to workpiece through spray gun (not shown).This opening 301 is a contraction mouth, thereby reduces the spray material in housing 30 high speed rotary courses, is splashed to the occurrence probability of the phenomenon the outer cover 1 of sand-blasting machine 200 from opening 301.Close door-plate 7, the spray material evenly also is coated to the surface of workpiece fully under the high speed rotation of housing 30.Because the spatial volume of this housing 30 is less, so the spray material can increase in limited space and the contact probability of workpiece.
In this embodiment, the spray material that diameter is bigger can become the less spray material of diameter through rotating at a high speed in housing 30, from through hole 312, directly be thrown out of this housing 30 then, and drops in the taper spray material accepting groove 5.This whirlwind tube 2 can form the high speed swirling eddy, and through circulation canal 4 outer cover 1 inner air is upwards extracted, thereby has avoided the bigger spray material of weight to enter into circulation canal 4.So just can avoid spraying the wearing and tearing of material effectively to circulation canal 4.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any Reference numeral in the claim be regarded as limit related claim.
In addition; Describing according to embodiment though should be appreciated that this specification, is not that each embodiment only comprises an independently technical scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technical scheme among each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
