Description
Technical field
The invention belongs to EVA foaming machinery field, relate to the improvement of the large-scale foaming machine structure of a kind of EVA, particularly relate to a kind of vibration and noise reducing device be applied in large-scale EVA foaming machine.
Background technology
Large-scale EVA foaming machine in generally using at present, no matter import or domestically produced machine, its hierarchy is all made up of vertical riser and the demixing plate be fixed thereon, when machine is in die opening state, because the horizontal stripe of heating plate can directly contact with demixing plate, and demixing plate is without the design of vibration damping aspect, so, strong shock can be formed between heating plate and demixing plate, therefore, will there is the shortcoming that impact is large, machine vibration is large, noise is large, the fatigue life of heating plate horizontal stripe is low in this structure.
In addition, applicant applied for " a kind of layering vibration absorber being applied to small-sized EVA foaming machine " (patent No.: 201020265272.1) on July 14th, 2010, the layering vibration absorber of setting forth in this patent not only structure is simple but also be only applicable to the little small-sized EVA foaming machine of impact, because large-scale EVA foaming machine can produce stronger impact in running, so the simple layering vibration absorber of the inapplicable this structure of large-scale EVA foaming machine.
Summary of the invention
In order to make up the defect that the impact existing when directly contacting with demixing plate of above-mentioned heating plate horizontal stripe is large, machine vibration large, the fatigue life of heating plate horizontal stripe is low, the invention provides a kind of vibration and noise reducing device be applied in large-scale EVA foaming machine, it can reduce the impact strength of horizontal stripe to demixing plate of heating plate effectively, and the vibration of complete machine can be alleviated, reduce noise, the final fatigue life extending oil cylinder and heating plate horizontal stripe.
In order to achieve the above object, the present invention takes following concrete technical measures: a kind of vibration and noise reducing device be applied in large-scale EVA foaming machine, and its architectural feature is, it comprises main vibration absorber, layering vibration and noise reducing device two large divisions,
Wherein, main vibration absorber is by vertical riser, demixing plate, dive key, vibration proof mounting, parallels one, damping block, collision block and adjustment screw composition, oil cylinder and the seat of honour are connected into a closed framework respectively by many root posts and multiple nut combinations, the vertical riser of more than one piece by screw one respectively with oil cylinder, the seat of honour is fixedly connected, more than one piece demixing plate passes through dive key, screw three is connected on vertical riser, vertical riser bottom demixing plate is fixed with by screw two vibration proof mounting bearing heating plate gravity and impulsive force, adjustment screw is disposed with from top to bottom in vibration proof mounting inside, parallels one, damping block and collision block, demixing plate is supported on collision block.
Damping block below collision block can play the effect of vibration damping, and damping block adopts polyurethane material to make.
Wherein, layering vibration and noise reducing device is made up of layering vibration proof mounting, elastomer block, parallels two, shaft shoulder screw, layering vibration and noise reducing device is arranged on demixing plate, demixing plate is processed with step, more than one piece layering vibration proof mounting is connected on demixing plate by screw four, elastomer block, parallels two and shaft shoulder screw is disposed with from bottom to top in layering vibration proof mounting inside, the bottom of shaft shoulder screw run through layering vibration proof mounting top and with parallels two socket, the bottom of shaft shoulder screw is finally arranged at the top of elastomer block, and heating plate horizontal stripe is supported on shaft shoulder screw.
In layering vibration and noise reducing device, elastomer block plays the effect of vibration and noise reducing, and elastomer block adopts elastomeric material to make.
When foaming process terminates, machine is by automatic die sinking, and because cavity pressure makes heating plate decline rapidly, the horizontal stripe on heating plate touches shaft shoulder screw, and impulsive force is delivered in elastomer block by shaft shoulder screw; From large range of structures, demixing plate can slide along dive key in the vertical direction on vertical riser, and the impulsive force of all heating plates finally all can be delivered on damping block by the collision block under demixing plate.Material due to elastomer block is rubber, the material of damping block is polyurethane, this bi-material is according to its characteristic, the impact that not only Absorbable rod was strong but also can not Powerful Rebound, thus reach the object alleviating complete machine oscillation, reduce noise, extend oil cylinder and heating plate horizontal stripe fatigue life.
Beneficial effect of the present invention is, it can reduce the impact strength of horizontal stripe to demixing plate of heating plate effectively, and can alleviate the vibration of complete machine, reduces noise, the final fatigue life extending oil cylinder and heating plate horizontal stripe.
Below in conjunction with drawings and Examples, the present invention is illustrated further.
