Description

Technical Field

[0001] The present invention relates to a blanking mechanism, and more specifically, to an energy-saving automatic blanking mechanism for alumina ceramic raw materials. Background Art

[0002] The Chinese patent document with the authorization announcement number CN116922563B and the name of an automatic blanking mechanism for alumina ceramic raw materials discloses an automatic blanking mechanism for alumina ceramic raw materials, which mainly solves the problem that after the alumina ceramic raw materials come out of the forming column of the tank body, they are likely to adhere to the conveyor belt. By arranging a plurality of heating plates above the belt to pre-dry the alumina ceramic raw materials on the first belt, the viscosity of the alumina ceramic raw materials is reduced, so as to avoid adhering to the first belt.

[0003] When the alumina ceramic raw materials fall on the first belt, they are relatively stationary with respect to the first belt, and the heating plates heat from above the first belt. At this time, it is difficult to heat the surface where the alumina ceramic raw materials are adhered to the first belt well to reduce the adhesiveness, and high-power heating is required to transfer the heat to the adhered surface of the alumina ceramic raw materials in a short time, but this will greatly increase the energy consumption. In addition, a cold air device is arranged below the first belt to quickly cool the surface of the first belt, which also increases the energy consumption. At the same time, the setting of one hot and one cold will also affect their respective effects, resulting in energy consumption losses. Summary of the Invention

[0004] In view of the above deficiencies of the prior art, the present invention provides an energy-saving automatic blanking mechanism for alumina ceramic raw materials that can reduce the adhesiveness of alumina ceramic raw materials and has low energy consumption.

[0005] The above technical object of the present invention is achieved through the following technical solutions:

[0006] An energy-saving automatic blanking mechanism for alumina ceramic raw materials includes a mixing component with a forming hole, and a cutting component for cutting the ceramic raw materials extruded from the forming hole. The forming hole has one and a circular cross-section, and further includes:

[0007] A material receiving component with an anti-adhesive material receiving surface, which is used to move and receive the ceramic raw materials extruded from the forming hole, keep the ceramic raw materials lying flat on the material receiving surface, continue to move to a preset position after the cutting component cuts the ceramic raw materials, and let the ceramic raw materials on it roll down obliquely;

[0008] A material discharging component, which is inclinedly arranged below the material receiving component, and has a smooth receiving surface on it, which is used to receive the rolling ceramic raw materials and let the ceramic raw materials roll from the high end to the low end and enter the next process;

[0009] A heating component, which is arranged below the material discharging component and close to the receiving surface, and is used to heat the receiving surface.

[0010] Furthermore, the discharging assembly can move obliquely and further includes a driving assembly. The driving end of the discharging assembly is connected to the discharging assembly and is used to push the discharging assembly to move obliquely in a small amplitude reciprocally.

[0011] Furthermore, the discharging assembly includes a first guide rail mechanism arranged obliquely and a metal plate arranged on the first guide rail mechanism. The metal plate is provided with a smooth upper surface, and the upper surface is the receiving surface. The pushing end of the driving assembly is connected to the metal plate to drive the metal plate to move reciprocally.

[0012] Furthermore, the metal plate is wavy and the undulating direction is perpendicular to the inclined direction, and the radian of the wave valley is greater than that of the wave peak.

[0013] Furthermore, the heating assembly includes a plurality of heating elements arranged uniformly. Each heating element is close to the bottom surface of the wave peak of the metal plate.

[0014] Furthermore, it further includes a box body with a discharging port. The material receiving assembly, the discharging assembly, the driving assembly and the heating elements are all arranged in the box body. The low end of the discharging assembly faces the discharging port. The mixing assembly is arranged at the top of the box body and the part where the forming holes are located is at the highest position inside the box body.

[0015] Furthermore, the material receiving assembly includes a second guide rail mechanism, a material receiving plate, an elastic member, a top rod and a pushing member. The material receiving plate is arranged on the second guide rail mechanism and can rotate between horizontal and obliquely downward. The elastic member abuts against the bottom surface of the material receiving plate to keep it in a horizontal state. The pushing member is used to push the second guide rail mechanism to make the material receiving plate move reciprocally. The top rod is located on one side of the second guide rail mechanism. When the pushing member drives the material receiving plate to move to receive the ceramic raw material extruded from the forming holes, the top end of the top rod abuts against the bottom surface of the material receiving plate. When the material receiving plate disengages from contact with the top rod, the material receiving plate is located above the high end of the discharging assembly.

[0016] Furthermore, it further includes an inclined transition member arranged between the material receiving assembly and the discharging assembly. The transition member is provided with an anti-sticking arc surface, so that the ceramic raw material rolling from the material receiving assembly accelerates and rolls through the arc surface and then enters the high end of the discharging assembly.

[0017] Advantages of the present invention: The present invention uses a forming hole with a circular cross-section, so that the ceramic raw material becomes cylindrical after extrusion. Then, a material receiving assembly with an anti-adhesive surface is used to receive the ceramic raw material. During the receiving process, a moving method is adopted to keep the final ceramic raw material lying flat on the material receiving surface. At this time, the ceramic raw material is allowed to roll obliquely downward onto the smooth receiving surface of the discharging assembly and move from the high end to the low end of the receiving surface in a rolling manner to enter the next process. This can reduce the pressure between the ceramic raw material and the receiving surface, thereby reducing the adhesiveness. At the same time, a heating assembly is arranged close to the receiving surface for heating, further reducing the adhesion. The heating element is close to the lower part of the receiving surface, and the heat rising can more efficiently heat the receiving surface. Moreover, it directly heats the receiving surface to heat the part of the ceramic raw material in contact with the receiving surface, and can heat with lower energy consumption and reduce the adhesion.

Therefore, it should not be construed as a limitation to the present invention.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0026] Referring to Figures 1 to 3 , an energy-saving automatic feeding mechanism for alumina ceramic raw materials, comprising a mixing component 1 with a forming hole 11, a cutting component 2, a receiving component 3, a discharging component 4, and a heating component.

[0027] The cutting component 2 is used to cut the ceramic raw material extruded from the forming hole 11, and this cutting component 2 adopts the structure of the existing tool rotation cutting. The receiving component 3 has an anti-adhesive receiving surface, which is used to move and receive the ceramic raw material extruded from the forming hole 11, keep the ceramic raw material lying flat on the receiving surface, continue to move to a preset position after the cutting component 2 cuts the ceramic raw material, and let the ceramic raw material on it roll down obliquely. When cutting the ceramic raw material, the cutting direction of the tool is opposite to the moving and receiving direction of the receiving component 3, ensuring that it can better maintain a straight bar shape and fall on the receiving surface after cutting.

[0028] The discharging component 4 is inclined and arranged below the receiving component 3, and it is provided with a smooth receiving surface for receiving the rolling ceramic raw material and allowing the ceramic raw material to roll from the high end to the low end and enter the next process. The heating component is arranged below the discharging component 4 and close to the receiving surface for heating the receiving surface.

[0029] The forming hole 11 has one and a circular cross-section, making the alumina ceramic raw material extruded from the forming hole 11 of the mixing component 1 into a cylindrical shape, enabling it to have a rolling structure. By the way of rolling down by its own weight, it can reduce the pressure between the ceramic raw material and its contact surface and reduce the adhesiveness. And the heating component directly heats the receiving surface, which can heat with lower energy consumption and reduce adhesiveness compared with the prior art, being more energy-saving.

[0030] In one embodiment, as Figure 1As shown, the discharging assembly 4 can move obliquely. It further includes a driving assembly 5. The driving assembly 5 uses a motor 51 to drive an eccentric wheel, which is connected to the discharging assembly 4 through a connecting rod 52 and is used to push the discharging assembly 4 to move reciprocally and obliquely in a small range. Through the reciprocating oblique movement, the ceramic raw materials can roll more smoothly and reduce adhesion. Specifically, the discharging assembly 4 includes an inclined first guide rail mechanism 41 and a metal plate 42 provided on the first guide rail mechanism 41. The metal plate 42 has a smooth upper surface, and the upper surface is the receiving surface. The pushing end of the driving assembly 5 is connected to the metal plate 42 to drive the metal plate 42 to move reciprocally. The metal plate 42 is preferably made of stainless steel plate, and its upper surface is polished or chrome-plated to make the surface smoother and better reduce the adhesion when the ceramic raw materials contact it.

[0031] In one embodiment, as Figure 3 shown, the metal plate 42 is wavy and the undulating direction is perpendicular to the inclined direction, and the radian of the wave valley is greater than that of the wave peak. In this way, the contact surface between the ceramic raw materials and the metal plate 42 can be reduced, making the rolling more smooth. In this structure, the heating assembly includes a plurality of heating elements 6 arranged uniformly. Each heating element 6 is close to the bottom surface of the wave peak of the metal plate 42. In this way, the arc wave peak semi-wraps the heating element 6, making the heat transfer efficiency higher and heating the metal plate 42 more efficiently.

[0032] In one embodiment, as Figure 1 shown, it further includes a box body with a discharging port. The receiving assembly 3, the discharging assembly 4, the driving assembly 5 and the heating element 6 are all arranged in the box body. The lower end of the discharging assembly 4 faces the discharging port. The mixing assembly 1 is arranged at the top of the box body and the part where the forming holes 11 are located is at the highest position inside the box body. In this way, the heat dissipated by the heating assembly into the box body will concentrate on the part where the forming holes 11 are located to preheat the ceramic raw materials at the forming holes 11, reducing the viscosity of the extruded ceramic raw materials.

[0033] In one embodiment, as Figure 2 shown, the receiving assembly 3 includes a second guide rail mechanism 31, a receiving plate 32, an elastic member (not shown in the figure), a top rod 33 and a pushing member 34. The pushing member 34 is preferably a cylinder, and the elastic member is a torsion spring. The receiving plate 32 is arranged on the second guide rail mechanism 31 and can rotate between horizontal and obliquely downward. The elastic member abuts against the bottom surface of the receiving plate 32 to keep it in a horizontal state. The pushing member 34 is used to push the second guide rail mechanism 31 to make the receiving plate 32 move reciprocally. The top rod 33 is located on one side of the second guide rail mechanism 31 and is used to, when the pushing member 34 drives the receiving plate 32 to move to receive the ceramic raw materials extruded from the forming holes 11, its top end abuts against the bottom surface of the receiving plate 32. When the receiving plate 32 disengages from contact with the top rod 33, the receiving plate 32 is above the high end of the discharging assembly 4. As Figure 2As shown, the position of the ejector rod 33 is located between the forming hole 11 and the pusher 34. When the pusher 34 drives the material receiving plate 32 to move to the position closest to the pusher 34, the forming hole 11 is located at the end of the material receiving plate 32 away from the pusher 34, and the top end of the ejector rod 33 abuts against the material receiving plate 32 to keep the material receiving plate 32 horizontal. When the forming hole 11 discharges materials, the pusher 34 drives the material receiving plate 32 to move away from the pusher 34 at an appropriate speed. At this time, the viscous ceramic raw materials will gradually be placed flat on the material receiving plate 32. When the material receiving plate 32 continues to move until it disengages from the ejector rod 33 after being cut off, under the action of the gravity of the ceramic raw materials, the material receiving plate 32 rotates downward, and the ceramic raw materials roll off from the material receiving plate 32. At this time, the position where the material receiving plate 32 disengages from the ejector rod 33 is the preset position. Subsequently, the elastic member acts to reset the material receiving plate 32 to the horizontal state, and the pusher 34 drives the material receiving plate 32 to move to the position closest to the pusher 34 to start the next operation.

[0034] In one embodiment, as Figure 1 shown, it further includes an inclined transition member 7 provided between the material receiving assembly 3 and the discharging assembly 4. The transition member 7 is provided with an anti-adhesive arc surface, so that the ceramic raw materials rolling off from the material receiving assembly 3 are accelerated and rolled through the arc surface and then enter the high end of the discharging assembly 4. Through the acceleration of the transition member 7, the rolling speed of the ceramic raw materials can be further increased, and adhesion can be reduced. The material receiving plate 32 and the transition member 7 are made of the same material, preferably a Teflon plate or a polished alumina ceramic plate. The Teflon plate has a low surface energy and excellent anti-adhesion, and the polished alumina ceramic plate also has excellent anti-adhesion after polishing. The alumina ceramic plate can also be coated with a boron nitride coating on the surface to further improve the anti-adhesion.

[0035] The above embodiments are merely explanations of the present invention, and they are not limitations on the present invention. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
