Description

Technical Field

[0001] This utility model relates to the field of brick cutting machine feeding technology, specifically to a brick cutting machine feeding structure. Background Technology

[0002] A brick cutter is a machine specifically designed for cutting refractory materials. It is primarily used to produce various types of refractory bricks, such as lightweight refractory bricks, clay refractory bricks, high-alumina refractory bricks, corundum refractory bricks, and wear-resistant bricks. In refractory material production, the final step is to mix and shape the refractory materials, then cut them using a brick cutter before firing. This process is mainly for producing a wide variety of refractory bricks. When using a brick cutter, it is necessary to use an appropriate feed to cut bricks of different sizes.

[0003] When cutting refractory materials with a brick cutter, unstable feeding can lead to uneven brick dimensions and fluctuating cutting speeds, affecting production efficiency and cutting quality. Furthermore, the handling and placement of cut bricks require more time and effort for subsequent firing processes; improper handling may damage the bricks. Therefore, we propose a new feeding structure for the brick cutter to ensure smooth production. Utility Model Content

[0006] Preferably, the feeding structure includes a concave plate, the lower surface of which is in contact with the upper surface of the circular roller, and the rear side of the concave plate is disposed between the inner sidewalls of the square frame. Circular slots are provided on both sides of the concave plate, and multiple sets of circular slots are arranged sequentially. Protrusions are symmetrically fixedly connected to the upper surface of the concave plate. Stone pads are fastened to the outer walls of two protrusions. The sidewalls of the stone pads are in contact with the inner wall of the concave plate, and the upper surface of the stone pads is in clearance fit with the lower surface of the cutter.

[0007] Preferably, the device further includes a positioning structure, wherein there are two positioning structures arranged symmetrically in the horizontal direction, the outer wall of the positioning structure is fixedly connected to the inner cavity of the square frame, and one side of the positioning structure penetrates the inner cavity of the square frame.

[0008] Preferably, the positioning structure includes a cylinder, the outer wall of which is fixedly connected to the inner cavity of the square frame, a compression spring is fixedly connected to one end of the inner wall of the cylinder, a push block is fixedly connected to the other end of the compression spring, the outer wall of the push block is clearance-fitted with the inner wall of the cylinder, a bracket is fixedly connected to the other end of the push block, and a circular block is rotatably connected to the center of the bracket, the side wall of the circular block is engaged with the circular groove of the concave plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When cutting refractory bricks, the refractory material is diluted and mixed into a clay-like state beforehand. Then, the refractory material is placed on the surface of the feeding structure. The feeding structure is composed of a concave plate and a stone pad, and is conveyed by a roller at the bottom. At the same time, positioning structures are set on both sides. A rotatable round block is pushed by a compression spring. The round block engages with the round slot of the feeding structure, fixing the feeding structure directly below the cutter. The round slots are evenly distributed. When pushing, the spring is compressed, causing the round block to retract and engage with the adjacent round slot, achieving the same feeding distance and ensuring the accuracy of the brick cutting position. The operator can more easily control the feeding structure. After the cutting work is completed, the stone pad engaged with the concave plate is removed, and the brick is directly placed into the combustion furnace for firing. This reduces the material handling process and avoids deformation when shoveling down the refractory bricks, ensuring the smooth progress of the production process. Attached Figure Description

[0018] The feeding structure 7 includes a concave plate 71, the lower surface of which is in contact with the upper surface of the circular roller 6, and the rear side of the concave plate 71 is located between the inner sidewalls of the square frame 2. Circular slots are provided on both sides of the concave plate 71, and multiple sets of circular slots are arranged sequentially. Protrusions 72 are symmetrically fixedly connected to the upper surface of the concave plate 71. Stone pads 73 are fastened to the outer walls of the two protrusions 72. The sidewalls of the stone pads 73 are in contact with the inner wall of the concave plate 71, and the upper surface of the stone pads 73 is in clearance fit with the lower surface of the cutter 5.

[0019] It also includes a positioning structure 8, of which there are two, and they are arranged symmetrically in the horizontal direction. The outer wall of the positioning structure 8 is fixedly connected to the inner cavity of the square frame 2, and one side of the positioning structure 8 penetrates the inner cavity of the square frame 2.

[0020] The positioning structure 8 includes a cylinder 81, the outer wall of which is fixedly connected to the inner cavity of the square frame 2. A compression spring 82 is fixedly connected to one end of the inner wall of the cylinder 81, and a push block 83 is fixedly connected to the other end of the compression spring 82. The outer wall of the push block 83 is clearance-fitted with the inner wall of the cylinder 81. A bracket 84 is fixedly connected to the other end of the push block 83. A circular block 85 is rotatably connected to the center of the bracket 84. The side wall of the circular block 85 is engaged with the circular groove of the concave plate 71.

[0021] Working Principle: During the preparation of refractory material for brick cutting, the refractory material is diluted and mixed into a clay-like state beforehand. It is then placed in a cuboid shape on the surface of the feeding structure 7. The feeding structure 7 contacts the clay-like refractory material through a stone pad 73. The stone pad 73 is then placed on the inner wall of the concave plate 71, simultaneously engaging with the protrusions 72 on both sides. The bottom of the concave plate 71 is in contact with the rollers 6. Multiple rollers 6 are arranged and positioned at the center of the base plate 1. During brick cutting, the operator pushes the feeding structure 7 to move it across the surface of the rollers 6, passing through the square frame 2. A positioning structure 8 is symmetrically arranged inside the square frame 2, fixed to it by a cylinder 81. A compression spring 82 inside the cylinder 81 pushes a pusher block 83.

At the same time, a concave block 4 is set between the cutter 5 and the hydraulic cylinder 3. The cutter 5 is fixed by bolts passing through the concave block 4. Different blades can be selected according to the shape of the brick. After the clay-like refractory material is cut, the hydraulic cylinder 3 is closed, and the feed structure 7 continues to be pushed forward. At the same time, the compression spring 82 is compressed, and the circular block 85 rotates against the outer wall of the concave plate 71 and engages with the adjacent circular slot. The hydraulic cylinder 3 provides power to perform the cutting work. At the same time, the concave plate 71 with different circular slot spacing can be selected according to the specifications of the refractory brick. After the cutting work is completed, the stone pad 73 that is engaged with the concave plate 71 is removed and placed directly into the combustion furnace for firing, reducing the material handling process and avoiding deformation when shoveling down the refractory brick.
