Description

Technical Field

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

[0002] Patent publication number CN116922563B, titled "Automated Unloading Mechanism for Alumina Ceramic Raw Materials," discloses an automated unloading mechanism for alumina ceramic raw materials. This mechanism primarily addresses the problem of alumina ceramic raw materials sticking to the conveyor belt after exiting the forming column of a tank. By placing multiple heating plates above the belts, the alumina ceramic raw materials on the first belt are pre-dried, reducing their viscosity and preventing them from sticking to the first belt.

[0003] When the alumina ceramic material lands on the first belt, it remains stationary relative to the belt, while the heating plate heats it from above. This makes it difficult to effectively heat the surface where the alumina ceramic material adheres to the belt to reduce adhesion. High-power heating is required to quickly transfer heat to the surface, but this significantly increases energy consumption. Furthermore, a cooling system is installed below the first belt to rapidly cool the surface, further increasing energy consumption. Furthermore, the dual heating and cooling configurations affect their effectiveness, resulting in energy loss. Summary of the Invention

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

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] An energy-saving automatic feeding mechanism for alumina ceramic raw materials, comprising a mixing assembly with a forming hole and a cutting assembly for cutting the ceramic raw materials extruded from the forming hole, wherein the forming hole has one and a circular cross section, and further comprising:

[0007] The receiving assembly has an anti-stick receiving surface, which is used to move and receive the ceramic raw materials extruded from the forming hole, so that the ceramic raw materials remain flat on the receiving surface, and continue to move to a preset position after the cutting assembly cuts the ceramic raw materials, allowing the ceramic raw materials on it to roll down obliquely;

[0008] The discharging assembly is tilted and arranged below the receiving assembly. It is provided with a smooth receiving surface for receiving the rolled ceramic raw materials, allowing the ceramic raw materials to roll from the high end to the low end and enter the next process.

[0009] The heating component is arranged below the discharging component and close to the receiving surface, and is used for heating the receiving surface.

[0010] Furthermore, the discharging assembly can move obliquely and also includes a driving assembly, and the driving end of the discharging assembly is connected to the discharging assembly for driving the discharging assembly to move back and forth obliquely in a small amplitude.

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

[0012] Furthermore, the metal plate is wavy, the undulating direction is perpendicular to the tilting direction, and the curvature of the trough is greater than the curvature of the crest.

[0013] Furthermore, the heating assembly includes a plurality of evenly arranged heating elements, each of which is close to the bottom surface of the wave crest of the metal plate.

[0014] Furthermore, it also includes a box body with a discharge port, and the material receiving component, discharge component, drive component and heating element are all arranged in the box body, the lower end of the discharge component faces the discharge port, the mixing component is arranged at the top of the box body and the forming hole is located at the highest point in the box body.

[0015] Furthermore, the material receiving assembly includes a second guide rail mechanism, a material receiving plate, an elastic member, a push rod and a pushing member. The material receiving plate is arranged on the second guide rail mechanism and can rotate between horizontal and oblique downward. The elastic member presses 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 back and forth. The push rod is located on one side of the second guide rail mechanism and is used for the top end of the material receiving plate to press against the bottom surface of the material receiving plate when the pushing member drives the material receiving plate to move to receive the ceramic raw material extruded from the forming hole. When the material receiving plate is out of contact with the push rod, the material receiving plate is located above the high end of the discharge assembly.

[0016] Furthermore, it also includes an inclined transition piece arranged between the material receiving assembly and the material discharging assembly, and the transition piece is provided with an anti-sticking arc surface, so that the ceramic raw materials rolling down from the material receiving assembly are accelerated by the arc surface and then enter the high end of the material discharging assembly.

[0017] The beneficial effects of the present invention are as follows: the present invention adopts a forming hole with a circular cross-section, so that the ceramic raw material becomes cylindrical after extrusion, and then a receiving component with an anti-adhesive material surface is used to receive the ceramic raw material. A moving method is adopted during receiving so that the final ceramic raw material remains flat on the receiving surface. At this time, the ceramic raw material is allowed to roll obliquely downward onto the smooth receiving surface of the discharging component, and a rolling method is adopted to move from the high end of the receiving surface to the low end to enter the next process, which can reduce the pressure between the ceramic raw material and the receiving surface and thus reduce adhesion. At the same time, a heating component is set close to the receiving surface for heating to further reduce adhesion. The heating element is close to the bottom of the receiving surface, and the rising heat can heat the receiving surface more efficiently, and the receiving surface is directly heated to heat the part of the ceramic raw material in contact with the receiving surface, which can heat with lower energy consumption and reduce adhesion.

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

[0027] The cutting assembly 2 is used to cut the ceramic material extruded from the forming hole 11. This cutting assembly 2 adopts the existing rotary cutting mechanism of the cutting tool. The receiving assembly 3 has a non-stick receiving surface for receiving the ceramic material extruded from the forming hole 11, which is kept flat on the receiving surface. After the cutting assembly 2 cuts the ceramic material, it continues to move to a preset position, allowing the ceramic material on it to roll diagonally downward. When cutting the ceramic material, the cutting direction of the cutting tool is opposite to the direction of movement of the receiving assembly 3, ensuring that the ceramic material falls on the receiving surface in a straight line after cutting.

[0028] The discharging assembly 4 is tilted and arranged below the receiving assembly 3. It is provided with a smooth receiving surface for receiving the rolled ceramic raw materials, allowing the ceramic raw materials to roll from the upper end to the lower end and enter the next process. The heating assembly is arranged below the discharging assembly 4 and close to the receiving surface for heating the receiving surface.

[0029] The forming hole 11 has a single, circular cross-section, which allows the alumina ceramic material extruded from the forming hole 11 of the mixing assembly 1 to form a cylindrical shape, giving it a rolling structure. By rolling down under its own weight, the pressure on the contact surface between the ceramic material and the material is reduced, thereby reducing adhesion. The heating assembly directly heats the receiving surface, achieving lower energy consumption and reducing adhesion compared to existing technologies, thus being more energy-efficient.

[0030] In one embodiment, if Figure 1As shown, the discharging assembly 4 can be obliquely moved, and further comprises a driving assembly 5, which adopts a motor 51 to drive an eccentric wheel, and is connected with the discharging assembly 4 through a connecting rod 52, and is used to push the discharging assembly 4 to move obliquely with a small amplitude. Through the oblique reciprocating movement, the ceramic raw material can be rolled more smoothly, and the adhesion is reduced. Specifically, the discharging assembly 4 comprises a first guide rail mechanism 41 arranged obliquely, and a metal plate 42 arranged on the first guide rail mechanism 41, wherein the metal plate 42 is provided with a smooth upper surface, the upper surface is the receiving surface, and the pushing end of the driving assembly 5 is connected with the metal plate 42 to drive the metal plate 42 to move reciprocatingly. The metal plate 42 is preferably made of stainless steel plate, and the upper surface is polished or plated with chromium to make the surface smoother, thereby reducing the adhesion of the ceramic raw material when contacting with the metal plate 42.

[0031] In an embodiment, as shown in Figure 3 the metal plate 42 is in a wave shape and the direction of the undulation is perpendicular to the oblique direction, and the curvature of the wave trough is greater than the curvature of the wave crest, so that the contact surface of the ceramic raw material with the metal plate 42 is reduced, and the rolling is more smooth. In this structure, the heating assembly comprises a plurality of heating elements 6 arranged uniformly, and each of the heating elements 6 is close to the bottom surface of the wave crest of the metal plate 42, so that the arc-shaped wave crest semi-encloses the heating element 6, and the heat transfer efficiency is higher, and the metal plate 42 is heated more efficiently.

[0032] In an embodiment, as shown in Figure 1 the box with a discharging port, the receiving assembly 3, the discharging assembly 4, the driving assembly 5 and the heating element 6 are arranged in the box, the low end of the discharging assembly 4 faces the discharging port, and the mixing assembly 1 is arranged on the top of the box and the part where the forming hole 11 is located is at the highest position in the box. In this way, the heat emitted by the heating assembly to the box will be concentrated to the part where the forming hole 11 is located, so as to preheat the ceramic raw material at the forming hole 11, and the adhesion of the extruded ceramic raw material is reduced.

[0033] In an embodiment, as shown in Figure 2 the receiving assembly 3 comprises 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 pneumatic cylinder, the elastic member is a torsion spring, the receiving plate 32 is arranged on the second guide rail mechanism 31 and can rotate between the horizontal and oblique directions, the elastic member abuts against the bottom surface of the receiving plate 32 to keep it in the horizontal state, the pushing member 34 is used to push the second guide rail mechanism 31 to move the receiving plate 32 reciprocatingly, and the top rod 33 is located on one side of the second guide rail mechanism 31 and is used to abut against the bottom surface of the receiving plate 32 when the pushing member 34 drives the receiving plate 32 to move to receive the ceramic raw material extruded from the forming hole 11, and when the receiving plate 32 is out of contact with the top rod 33, the receiving plate 32 is located above the high end of the discharging assembly 4. As Figure 2As shown, the push rod 33 is positioned between the forming hole 11 and the push member 34. When the push member 34 drives the receiving plate 32 to move closest to the push member 34, the forming hole 11 is located at the end of the receiving plate 32 away from the push member 34, and the top of the push rod 33 supports the receiving plate 32 to keep it horizontal. When the forming hole 11 is discharged, the push member 34 drives the receiving plate 32 to move away from the push member 34 at an appropriate speed. At this time, the viscous ceramic material gradually lies flat on the receiving plate 32. After being cut, the receiving plate 32 continues to move until it loses contact with the push rod 33. Under the action of the weight of the ceramic material, the receiving plate 32 rotates downward, and the ceramic material rolls off the receiving plate 32. At this time, the position where the receiving plate 32 loses contact with the push rod 33 is the preset position. The elastic member then acts to reset the receiving plate 32 to a horizontal state, and the push member 34 drives the receiving plate 32 to a position closest to the push member 34, and the next operation begins.

[0034] In one embodiment, if Figure 1 As shown, it also includes a transition piece 7 arranged at an angle between the material receiving assembly 3 and the material discharging assembly 4. The transition piece 7 is provided with an anti-sticking arc surface, so that the ceramic raw material rolling down from the material receiving assembly 3 is accelerated by the arc surface and then enters the high end of the material discharging assembly 4. The acceleration of the transition piece 7 can further accelerate the rolling speed of the ceramic raw material and reduce adhesion. The material receiving plate 32 and the transition piece 7 are made of the same material, preferably a Teflon plate or a polished alumina ceramic plate. The Teflon plate has low surface energy and excellent anti-stick properties, and the alumina ceramic plate also has excellent anti-stick properties after surface polishing. The alumina ceramic plate can also be coated with a boron nitride coating on the surface to further improve the anti-stick properties.

[0035] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
