Description

Technical Field

[0001] This utility model relates to the field of feeding refractory brick molding dies, and more specifically, to a feeding and initial compaction mechanism for refractory brick molding dies. Background Technology

[0002] Refractory materials are generally divided into two types: unshaped refractories and shaped refractories. Unshaped refractories, also called castables, are mixed powdery granules composed of various aggregates and one or more binders. They must be mixed thoroughly with one or more liquids before use and have strong fluidity. Shaped refractories generally refer to refractory bricks, which have standard and regular shapes, but can also be custom-made as needed. Refractory brick forming molds are tools used to manufacture refractory bricks, mainly used to press refractory raw materials into bricks of a certain shape under high pressure or other forming processes. Typically, the refractory brick raw material is added to the mold, and then pressed into shape using stamping equipment.

[0003] Based on the above, the inventors have discovered that existing refractory brick mold feeding structures mostly involve manually or mechanically adding refractory raw materials into the mold. Because the raw materials accumulate unevenly after entering the mold, this results in incomplete and loosely formed bricks. Typically, the raw materials are manually smoothed and compacted within the mold using tools, which is very cumbersome. Therefore, in view of this, the inventors have researched and improved the existing structure, providing a feeding and initial compaction mechanism for refractory brick molding dies, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a feeding and initial compaction mechanism for a refractory brick molding die. This mechanism can reciprocate and compact the raw material after it is added to the die, making the raw material flat and compact in the die.

[0006] 2. Technical Solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions.

[0008] A feeding and initial compaction mechanism for a refractory brick molding die includes a die body. Electric telescopic rods are fixedly installed on both sides of the die body. Connecting blocks are fixedly installed at the telescopic ends of the two electric telescopic rods. Support frames are fixedly installed at the top of the two connecting blocks. A feeding funnel is fixedly installed at one end of the horizontal side of the support frame. An electric ash discharge valve is fixedly connected to the discharge end of the feeding funnel. A fixing frame is fixedly installed on the outer wall of the bottom of the feeding funnel. Two pairs of telescopic rod bodies are fixedly installed at the bottom of the fixing frame. Fixing blocks are fixedly installed on the outer walls of the cylinders of the two pairs of telescopic rod bodies. A return spring is sleeved on the outer side of the telescopic end of each telescopic rod body. A U-shaped bracket is fixedly installed at the telescopic end of each pair of telescopic rod bodies. Compacting rollers are installed on the inner sides of the two U-shaped brackets via a rotating shaft.

[0009] Furthermore, the telescopic ends of the two electric telescopic rods are longer than the length of the mold body, and the support frame is U-shaped.

[0010] Furthermore, a reinforcing rib is fixedly installed on the inner side of the support frame, and the reinforcing rib is in the shape of a cross.

[0011] Furthermore, the fixed frame is H-shaped, and the positions of the two pairs of telescopic rod bodies are symmetrical to each other.

[0012] Furthermore, one end of the reset spring is fixedly connected to the outer wall of the fixing block, and the other end of the reset spring is fixedly connected to the outer wall of the U-shaped bracket.

[0013] Furthermore, the discharge end of the electric ash discharge valve is located between two rolling rollers, and the position of the rolling rollers corresponds to the position of the opening of the mold body.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This solution, through the installation of an electric telescopic rod, a telescopic rod body, a return spring, and a crushing roller, utilizes an electric telescopic rod to move a feeding hopper above the opening of the mold body. Simultaneously, the crushing roller contacts the outer wall of the mold body as the feeding hopper moves. The movement of the feeding hopper causes the edge of the mold body to push the crushing roller upwards, while the return spring compresses and the telescopic rod body retracts. Once the feeding hopper is above the mold body, the elasticity of the return spring allows the crushing roller to enter the interior of the mold body's opening, preventing jamming. Then, the electric ash discharge valve opens, and the electric telescopic rod moves the feeding hopper, allowing the raw material to fall between the two crushing rollers into the interior of the mold body, ensuring the material does not exceed the top of the crushing roller's outer wall. After feeding, the electric telescopic rod moves the feeding hopper back and forth, allowing the crushing roller and return spring to work together to initially crush and smooth the raw material. This device effectively improves the convenience of feeding refractory brick raw materials. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4 A feeding and initial compaction mechanism for a refractory brick molding die includes a die body 1. Electric telescopic rods 2 are fixedly installed on both sides of the die body 1. Connecting blocks 3 are fixedly installed at the telescopic ends of the two electric telescopic rods 2. Support frames 4 are fixedly installed at the top of the two connecting blocks 3. A feeding funnel 6 is fixedly installed at one end of the horizontal side of the support frame 4. An electric ash discharge valve 7 is fixedly connected to the discharge end of the feeding funnel 6. A fixing frame 8 is fixedly installed on the outer wall of the bottom end of the feeding funnel 6. Two pairs of telescopic rod bodies 9 are fixedly installed at the bottom end of the fixing frame 8. Fixing blocks 10 are fixedly installed on the outer walls of the cylinders of the two pairs of telescopic rod bodies 9. A return spring 11 is sleeved on the outer side of the telescopic end of each pair of telescopic rod bodies 9. U-shaped brackets 12 are fixedly installed at both ends. Roller rollers 13 are installed on the inner side of the two U-shaped brackets 12 via a rotating shaft. The device moves the feeding funnel 6 above the mold body 1 via an electric telescopic rod 2. Then, the electric ash discharge valve 7 is opened to allow the raw material to fall into the mold body 1. After the raw material is added, the support frame 4 is moved left and right by the electric telescopic rod 2, so that the roller rollers 13 can compact and flatten the raw material in the mold. Then, the telescopic end of the electric telescopic rod 2 is extended, so that the feeding funnel 6 is away from the top of the mold body 1. The stamping equipment can then drive the pressure plate to press and shape the raw material inside the mold body 1. This device can effectively improve the convenience of feeding brick raw materials.

[0026] See Figure 1 , 2 The telescopic ends of the two electric telescopic rods 2 are longer than the length of the mold body 1, and the support frame 4 is U-shaped. The inner side of the support frame 4 is fixedly equipped with reinforcing ribs 5, which are cross-shaped. Since the telescopic ends of the electric telescopic rods 2 are longer than the length of the mold body 1, the electric telescopic rods 2 can drive the feeding funnel 6 away from the top of the mold body 1, thereby avoiding the phenomenon of the mold body 1 interfering with the pressure plate on the stamping equipment. At the same time, the reinforcing ribs 5 can effectively improve the support strength and stability of the support frame 4.

[0027] See Figure 3 , Figure 4 The fixed frame 8 is H-shaped, and the positions of the two pairs of telescopic rod bodies 9 are symmetrical. One end of the return spring 11 is fixedly connected to the outer wall of the fixed block 10, and the other end of the return spring 11 is fixedly connected to the outer wall of the U-shaped bracket 12. By symmetrically setting the positions of the telescopic rod bodies 9, the force of the rolling roller 13 pressing on the raw material is more balanced.

[0028] See Figure 3 , Figure 4The discharge end of the electric ash discharge valve 7 is located between the two rollers 13, and the position of the rollers 13 corresponds to the position of the opening of the mold body 1. When the electric ash discharge valve 7 is opened to discharge material, the raw material will fall from between the two rollers 13 into the interior of the mold body 1. The raw material will not exceed the top of the outer wall of the rollers 13. When the feeding funnel 6 moves to the opening of the mold body 1, the rollers 13 will contact the outer edge of the opening of the mold body 1. Due to the movement of the feeding funnel 6, the edge of the mold body 1 pushes the rollers 13 upward. At the same time, the return spring 11 is compressed and the telescopic rod body 9 retracts. When the feeding funnel 6 moves above the mold body 1, the elasticity of the return spring 11 allows the rollers 13 to enter the interior of the opening of the mold body 1.

[0029] In use: First, the operator assembles the mold body 1 with the stamping equipment and adds raw material into the feeding funnel 6. Then, the electric telescopic rod 2 moves the feeding funnel 6 to above the opening of the mold body 1. As the feeding funnel 6 moves, the pressing roller 13 contacts the outer wall of the mold body 1. The movement of the feeding funnel 6 causes the edge of the mold body 1 to push the pressing roller 13 upward. At the same time, the return spring 11 is compressed and the telescopic rod body 9 retracts. When the feeding funnel 6 moves above the mold body 1, the elasticity of the return spring 11 allows the pressing roller 13 to enter the opening of the mold body 1. To prevent the pressing roller 13 from jamming when it moves into the mold body 1, the electric unloading valve 7 is then opened. The electric telescopic rod 2 drives the feeding funnel 6 to move, and the raw material will fall from between the two pressing rollers 13 into the mold body 1. The raw material will not exceed the top of the outer wall of the pressing roller 13. After the raw material is fed, the electric telescopic rod 2 drives the feeding funnel 6 to move back and forth, so that the pressing roller 13 and the return spring 11 work together to initially crush and smooth the raw material. Then the electric telescopic rod 2 drives the feeding funnel 6 away from the mold body 1, and the raw material in the mold body 1 can be pressed and shaped by the stamping plate.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
