Description

Technical Field

[0001] This utility model relates to the technical field of refractory material forming equipment, specifically a long-life brick ejector for an electric screw press brick machine. Background Technology

[0002] In the refractory materials industry, the electric screw brick press plays a crucial role as the main forming equipment for shaped products. This equipment uses a motor to drive a flywheel, which in turn drives a screw to rotate. This rotation drives a slider to perform the striking action, ultimately pressing the raw material into brick blanks of the desired shape. After the brick blanks are formed, they need to be ejected from the mold cavity by the brick ejection system, completing the entire forming process. Currently, the brick ejection system of electric screw brick presses generally adopts a brick ejector structure consisting of a bracket, a top-loading cylinder, and a insert plate. In this structure, the top-loading cylinder is mounted on the bracket, and its piston rod extends and retracts, causing the insert plate to move back and forth. When the insert plate moves to the center hole of the bracket and blocks the hole, the pull rod simultaneously drives the bracket upward, which in turn drives the top-loading rod inside the machine body to rise, thus ejecting the formed brick blank from the mold cavity. When the insert plate retracts, the top-loading rod falls down, preparing for the next brick pressing operation.

[0003] However, existing brick ejector structures have some problems during use. Due to the easy leakage of clay during the pressing process, some clay will enter the brick ejector and cause material accumulation. Long-term material accumulation not only increases the operating resistance of the brick ejector, but also puts additional burden on its structure, causing the brick ejector components to bend or break easily, thus affecting the stability and service life of the equipment. In addition, some current brick ejectors usually adopt an integrated design, that is, the brick ejector consists of a column and a top material leakage part. When the column bends or breaks due to long-term use or material accumulation, the whole structure needs to be replaced due to the integrity of the structure, which undoubtedly increases maintenance costs. Therefore, we propose a long-life brick ejector for electric screw press brick machines to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-5As shown in the figure, an embodiment of the present invention provides a long-life brick ejector for an electric screw brick press, comprising an ejector body 1, which includes a column 3 and a material discharge section 2. The column 3 is in movable contact with the material discharge section 2. The material discharge section 2 has a plurality of material discharge holes 4 arranged in a ring. A conical block 5 is fixedly connected to the inner wall of the bottom of the material discharge section 2. A cavity 6 is formed in the material discharge section 2. Two positioning rods 7 are welded to the inner walls of both sides of the cavity 6. A connecting rod 8 is slidably connected to the positioning rod 7. A first spring 9 is welded between the end of the connecting rod 8 and one side of the inner wall of the cavity 6. The other ends of the two connecting rods 8 on the same side are fixedly connected to the same connecting block 10. Two locking rods 11 are fixedly connected to one side of the connecting block 10. A first flexible steel rope 12 is fixedly connected to the other side of one of the two connecting blocks 10. A first fixed pulley 13 is rotatably connected to one side of the inner wall of the cavity 6. The first flexible steel rope 12... The end of the tube passes around one side of the first fixed pulley 13 and is fixedly connected to one side of another connecting block 10. A second fixed pulley 14 is rotatably connected to the inner wall of the other side of the cavity 6. A second flexible steel rope 15 is fixedly connected to the other side of one of the two connecting blocks 10. The end of the second flexible steel rope 15 extends to the outside of the material leakage part 2 and is fixedly connected to a pull ring 16. Two mounting blocks 17 are fixedly connected to the top of the column 3. Two fixing grooves 18 are opened on one side of the mounting block 17. The fixing grooves 18 are engaged with the corresponding clamping rods 11. The material leakage hole 4 is provided in the material leakage part 2 of the brick ejector body 1. The material leakage hole 4 is downward at an angle of 10° to 60°, which effectively solves the problem of material accumulation. The setting of the conical block 5 accelerates the flow of materials, improves the service life of the brick ejector body 1, and reduces the consumption of spare parts. Pulling the pull ring 16 can replace the damaged column 3, thereby reducing production costs.

[0026] In some embodiments, the first spring 9 is movably sleeved on the corresponding positioning rod 7, and the first spring 9 serves to reset the position.

[0027] In some embodiments, two rectangular holes 19 are formed on the bottom inner wall of the cavity 6, and the inner wall of the rectangular holes 19 is in active contact with the outer side of the corresponding mounting block 17.

[0028] In some embodiments, the cavity 6 is provided with four T-shaped rods 20, the ends of which extend to the outside of the material leakage part 2 and are fixedly connected to the top of the pull ring 16. The T-shaped rods 20 serve a positioning function.

[0029] In some embodiments, a second spring 21 is fixedly connected between the top inner wall of the T-shaped rod 20 and the bottom inner wall of the cavity 6, and the second spring 21 is movably sleeved on the corresponding T-shaped rod 20.

[0030] In some embodiments, the discharge hole 4 is inclined downwards at an angle of 10° to 60°. This design can effectively prevent material from accumulating at the discharge hole 4, because the material will slide smoothly down the inclined discharge hole 4 under the action of gravity, thereby avoiding blockage.

[0031] Working principle or structural principle: During use, the material leakage hole 4 is set in the material leakage section 2 of the brick ejector body 1. The material leakage hole 4 is angled downwards, ranging from 10° to 60°, which effectively solves the problem of material accumulation. Furthermore, the conical block 5 accelerates material flow, improving the service life of the brick ejector body 1 and reducing the consumption of spare parts. When the column 3 needs to be replaced, the pull ring 16 is pulled. The pull ring 16 moves the T-shaped rod 20 and compresses the second spring 21. Simultaneously, the pull ring 16 moves one connecting block 10 via the second flexible steel rope 15. One connecting block 10 moves another connecting block 10 via the first flexible steel rope 12, causing the two connecting blocks 10 to move away from each other. The connecting block 10 drives the corresponding connecting rod 8 to slide on the positioning rod 7 and compress the first spring 9, causing the connecting block 10 to separate the corresponding locking rod 11 from the fixing groove 18. Then, the damaged column 3 is removed, and the mounting block 17 on the new column 3 is inserted into the cavity 6 through the rectangular hole 19. When the top of the column 3 contacts the bottom of the leakage part 2, the tension on the pull ring 16 is released, and the first spring 9, which is in a compressed state, returns to its original position. Under the action of the elastic force of the first spring 9, the first spring 9 drives the corresponding connecting block 10 to move through the connecting rod 8. The connecting block 10 drives the locking rod 11 to engage with the corresponding fixing groove 18, fixing the new column 3, which can then be replaced, reducing production costs.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
