Description

Technical Field

[0001] This invention relates to the field of refractory material production, and more specifically to a device and process for preparing and molding medium-density insulating refractory bricks. Background Technology

[0002] Medium-density insulating refractory bricks are a type of medium-density refractory material that combines fire resistance and heat insulation properties. They are typically pressed into shape using a heavy-duty press, making the molding equipment used in their production crucial.

[0003] Chinese patent CN115319894B discloses a magnesia-carbon brick forming and processing device. A movable frame is slidably mounted on a base, and a sliding mechanism is connected to the movable frame. A weighing mechanism, a ton press, a grinding mechanism, and a cover plate mechanism are sequentially mounted on the movable frame. A discharge chute is also provided on the base, located on the brick output side of the cover plate mechanism. The sliding mechanism of this magnesia-carbon brick forming and processing device drives the movable frame to move, thereby realizing the movement of the weighing mechanism, ton press, grinding mechanism, and cover plate mechanism, thus achieving the processing of magnesia-carbon bricks. The processing of magnesia-carbon bricks can be carried out solely on the base, eliminating the need for brick transfer during production and preventing heat loss during transfer. Furthermore, the device boasts a high degree of automation, requiring no manual intervention throughout the entire process.

[0004] However, the inventors have discovered that in actual production, raw materials are usually manually fed into the molding device before being pressed. Furthermore, the raw materials are prone to scattering during feeding, requiring manual collection and refeeding. Additionally, medium-density insulating refractory bricks have a hollow structure in the center, generally requiring a fixed lower mold to pass through the molding device, thus making the center of the medium-density insulating refractory brick hollow. Therefore, when feeding the raw materials, they easily fall onto the lower mold, requiring manual cleaning after pressing, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a medium-density heat-insulating refractory brick preparation and molding device. The device uses a conveying component to transport raw materials, and a metering component and a feeding component to meter the raw materials into a molding tank. The material is then stamped and molded by a stamping component, enabling the medium-density heat-insulating refractory bricks to be formed quickly and improving the molding quality of the medium-density heat-insulating refractory bricks.

[0006] The technical solution of the present invention is as follows:

[0007] A medium-density heat-insulating refractory brick preparation and molding device includes a base and a top plate. A sliding plate is slidably arranged between the base and the top plate. A molding mold and a molding groove are arranged on the sliding plate. An injection component is arranged in the molding groove. An opening and closing component is arranged on the injection component. A conveying component and a metering component driven by the conveying component are arranged on the base. A stamping component is arranged on the top plate. The metering component is used to quantitatively convey the raw material into the injection component during the conveying process of the conveying component. The injection component is used to convey the raw material into the molding groove with the cooperation of the opening and closing component. The stamping component is used to stamp and mold the raw material.

[0008] As a preferred embodiment, the conveying assembly includes a cylinder fixedly mounted on a base, a partition fixedly mounted inside the cylinder, an auger rotatably mounted between the cylinder and the partition, and a motor fixedly mounted on the cylinder, wherein the output shaft of the motor is fixedly connected to the shaft of the auger.

[0009] As a preferred embodiment, the metering assembly includes a metering cylinder fixedly mounted on the cylinder body, a connecting pipe fixedly mounted between the cylinder body and the metering cylinder, a first piston and a second piston slidably mounted inside the metering cylinder, a pull rod fixedly mounted between the first piston and the second piston, an eccentric disk sleeved on the motor output shaft, a first connecting rod hinged to the eccentric disk, a second connecting rod hinged to the first piston, a sliding rod slidably mounted inside the metering cylinder, a first spring fixedly mounted between the second piston and the metering cylinder, and a delivery pipe fixedly mounted on the metering cylinder. The first connecting rod and the second connecting rod are hinged together, the sliding rod is fixedly connected to the second connecting rod, the first piston cooperates with the connecting pipe, and the second piston cooperates with the delivery pipe.

[0010] As a preferred embodiment, the injection assembly includes a support frame fixedly mounted on a base, a molding column fixedly mounted on the support frame, a molding cylinder fixedly mounted on the molding column, a through groove formed in the molding column, and an empty groove formed in the molding cylinder. The molding column and the molding groove are slidably fitted together, and the delivery pipe is fitted with the through groove and connected to the empty groove.

[0011] As a preferred embodiment, the opening and closing assembly includes several receiving cavities fixedly formed on the inner wall of the forming column, a sliding rod slidably disposed in the receiving cavity, a cover plate fixedly disposed on the sliding rod, and a second spring fixedly connected between the sliding rod and the receiving cavity, wherein the cover plate cooperates with the forming cylinder.

[0012] As a preferred embodiment, the stamping assembly includes a hydraulic rod slidably disposed on a top plate, a die head fixedly disposed on the hydraulic rod, and a cavity formed on the die head. A fixed die is disposed in the forming groove and has an opening. The cavity cooperates with the forming cylinder, and the die head cooperates with the fixed die.

[0013] As a preferred embodiment, the metering cylinder is provided with air tubes at both ends.

[0014] Another objective of this invention is to provide a process for preparing and molding medium-density insulating refractory bricks, comprising the following steps:

[0015] Step 1, Feeding process: The motor drives the auger to rotate, conveying the raw materials to the connecting pipe;

[0016] Step 2, Conveying Process: During the reciprocating sliding of the first and second pistons driven by the motor, the raw materials are quantitatively pushed into the conveying pipe;

[0017] Step 3, Injection Process: The raw material falls into the molding tank after the cover plate is opened;

[0018] Step 4, stamping process: After placing the fixed mold into the forming groove, the die head is lowered to stamp the fixed mold and form the raw material.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention is equipped with a conveying component and a metering component. When the auger conveys the raw material, it pushes the raw material into the forming trough in a metered manner, which improves the quality of medium-density heat-insulating refractory bricks while ensuring that the raw material will not scatter or fall onto the cover plate, thus reducing the time required for manual cleaning later.

[0021] 2. The present invention also includes an injection assembly and an opening and closing assembly. After the raw material is pushed into the conveying pipe, it opens the cover plate and enters the forming groove. The cover plate is used for indirect closing, so that there is no waste of raw material during pressing.

[0022] In summary, this invention has the advantages of high injection efficiency and good pressing effect, and is suitable for the refractory material production field. Attached Figure Description

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Example 1

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 11 As shown, a medium-density heat-insulating refractory brick preparation and molding device includes a base 1 and a top plate 2. A sliding plate 3 is slidably arranged between the base 1 and the top plate 2. A molding mold 4 and a molding groove 5 opened in the middle of the molding mold 4 are arranged on the sliding plate 3. An injection component 6 is arranged in the molding groove 5. An opening and closing component 7 is arranged on the injection component 6. A conveying component 8 and a metering component 9 driven by the conveying component 8 are arranged on the base 1. A stamping component 10 is arranged on the top plate 2. The metering component 9 is used to meterly convey the raw material into the injection component 6 during the conveying process of the conveying component 8. The injection component 6 is used to convey the raw material into the molding groove 5 with the cooperation of the opening and closing component 7. The stamping component 10 is used to stamp and mold the raw material. A fixed column is connected between the base 1 and the top plate 2. The sliding plate 3 is slidably arranged on the fixed column. A pull rod is arranged on both sides of the sliding plate 3 and a hydraulic cylinder is connected to the pull rod to drive the sliding plate 3 to rise and fall.

[0043] It is worth mentioning that, such as Figure 1 As shown, the conveying assembly 8 includes a cylinder 81 fixedly mounted on the base 1, a partition 82 fixedly mounted inside the cylinder 81, an auger 83 rotatably mounted between the cylinder 81 and the partition 82, and a motor 84 fixedly mounted on the cylinder 81. The output shaft of the motor 84 is fixedly connected to the shaft of the auger 83. A material box for loading raw materials is connected to the other side of the cylinder 81. In use, the motor 84 drives the auger 83 to rotate, and the auger 83 conveys the raw materials in the material box to the metering cylinder 91.

[0044] In addition, such as Figure 2 and Figure 3As shown, the metering assembly 9 includes a metering cylinder 91 fixedly mounted on the cylinder body 81, a connecting pipe 92 fixedly mounted between the cylinder body 81 and the metering cylinder 91, a first piston 93 and a second piston 94 slidably mounted inside the metering cylinder 91, a pull rod 95 fixedly mounted between the first piston 93 and the second piston 94, an eccentric disk 96 fixedly mounted on the output shaft of the motor 84, a first connecting rod 97 hinged to the eccentric disk 96, a second connecting rod 98 hinged to the first piston 93, a sliding rod 99 slidably mounted inside the metering cylinder 91, a first spring 910 fixedly mounted between the second piston 94 and the metering cylinder 91, and a delivery pipe 911 fixedly mounted on the metering cylinder 91. The first connecting rod 97 and the second connecting rod 98 are hinged together, the sliding rod 99 is fixedly connected to the second connecting rod 98, and the first piston 93 cooperates with the connecting pipe 92. The second piston 94 cooperates with the conveying pipe 911. The cavity between the conveying pipe 911, the connecting pipe 92, and the first piston 93 and the second piston 94 is filled with raw material. During use, the auger 83 always pushes the raw material into the space between the first piston 93 and the second piston 94 through the connecting pipe 92. The eccentric disk 96 drives the first piston 93 to slide back and forth through the first connecting rod 97 and the second connecting rod 98. The first piston 93 drives the second piston 94 to slide back and forth by pushing the raw material and the pull rod 95. During this process, the raw material is pushed into the conveying pipe 911. The raw material at the bottom of the conveying pipe 911 pushes the raw material at the top into the forming groove 5. The number of rotations or the rotation time of the eccentric disk 96 driven by the motor 84 are set to achieve a quantitative effect. When the number of rotations or the rotation time are reached, the motor 84 stops rotating, and the raw material is stamped and formed by the stamping assembly 10.

[0045] It needs to be emphasized that, such as Figure 7 and Figure 8 As shown, the injection assembly 6 includes a support frame 61 fixedly mounted on the base 1, a molding column 62 fixedly mounted on the support frame 61, a molding cylinder 63 fixedly mounted on the molding column 62, a through groove 64 opened in the molding column 62, and an empty groove 66 opened in the molding cylinder 63. The molding column 62 and the molding groove 5 are slidably engaged. The conveying pipe 911 is engaged with the through groove 64 and is connected to the empty groove 66.

[0046] It should be further explained that, such as Figure 4As shown, the opening and closing assembly 7 includes several receiving cavities 71 fixedly formed on the inner wall of the forming column 62, a sliding rod 72 slidably disposed in the receiving cavity 71, a cover plate 73 fixedly disposed on the sliding rod 72, and a second spring 74 fixedly connected between the sliding rod 72 and the receiving cavity 71. The cover plate 73 cooperates with the forming cylinder 63. In use, when the raw material is quantitatively conveyed into the forming column 62 and the forming cylinder 63, the raw material pushes open the cover plate 73, the second spring 74 is stretched, and the raw material falls into the forming groove 5 until the set amount is reached. After the motor 84 stops conveying the raw material, the cover plate 73 is covered back on the forming cylinder 63 under the action of the second spring 74. At this time, the top surface of the raw material is lower than the top surface of the cover plate 73, so the raw material will not fall onto the cover plate 73.

[0047] It is worth mentioning that, such as Figure 10 and Figure 11 As shown, the stamping assembly 10 includes a hydraulic rod 101 slidably mounted on the top plate 2, a die head 102 fixedly mounted on the hydraulic rod 101, and a cavity 103 formed in the die head 102. A fixed die 104 is provided in the forming groove 5, and a through opening 105 is provided on the fixed die 104. The cavity 103 cooperates with the forming cylinder 63, and the die head 102 cooperates with the fixed die 104. A drive device is connected to the die head 102 to drive the die head 102 to move up and down. In use, after the cover plate 73 is closed, it is manually or mechanically adjusted. The robotic arm places the fixed mold 104 on the raw material in the forming groove 5. Then, the drive device drives the mold head 102 to descend and press against the cover plate 73. The mold head 102 drives the fixed mold 104 to descend and press the raw material. The cover plate 73 slides in the cavity 103. After pressing, the mold head 102 rises and resets. The hydraulic cylinder drives the slide plate 3 and the forming mold 4 to descend until the medium-density heat-insulating refractory brick is fully exposed. The fixed mold 104 is removed from the end of the medium-density heat-insulating refractory brick by manual labor or robotic arm, and the medium-density heat-insulating refractory brick can then be removed.

[0048] Furthermore, such as Figure 9 As shown, both ends of the metering cylinder 91 are equipped with air tubes 11, and the first piston 93 and the second piston 94 facilitate air entry when sliding.

[0049] Example 2

[0050] like Figure 14 As shown, a process for preparing and molding medium-density insulating refractory bricks includes the following steps:

[0051] Step 1, Feeding process: Motor 84 drives auger 83 to rotate, conveying the raw materials to the connecting pipe 92;

[0052] Step 2, Conveying process: During the reciprocating sliding process of the first piston 93 and the second piston 94 driven by the motor 84, the raw material is quantitatively pushed into the conveying pipe 911;

[0053] Step 3, Injection Process: The raw material falls into the molding groove 5 after the cover plate 73 is opened;

[0054] Step 4, stamping process: After placing the fixed mold 104 into the forming groove 5, the die head 102 is lowered to stamp the fixed mold 104 and form the raw material.

[0055] Work process

[0056] Motor 84 drives auger 83 to rotate, conveying the raw material to connecting pipe 92. At the same time, motor 84 drives first piston 93 and second piston 94 to slide back and forth, quantitatively pushing the raw material into conveying pipe 911 for quantitative conveying. The raw material opens the cover plate 73 and falls into forming groove 5. Then, after the fixed mold 104 is placed into forming groove 5, the die head 102 descends to press the fixed mold 104, and the raw material is stamped and formed.
