Description

Technical Field

[0001] This utility model relates to the field of concrete brick blank processing technology, specifically a concrete brick blank side trimming device. Background Technology

[0002] Concrete brick blanks are precast building materials made from cement, aggregates, and water through molding and curing. They are mainly used in brick masonry, road paving, and other projects. In order to ensure that the size and shape of the bricks meet the design and construction requirements, maintain the flatness and consistency of the bricks, facilitate stacking and connection, thereby improving the overall quality and aesthetics of the structure and ensuring the stability and durability of the project, it is often necessary to trim the sides of the bricks.

[0003] An investigation revealed that a Chinese utility model patent discloses a side-cutting device for aerated concrete brick blanks (publication number: CN218342415U), comprising several cutting ropes, several connecting plates, several control components, and several bases. The cutting ropes are used to cut the raw material, which is symmetrically arranged on both sides. The connecting plates support the cutting ropes. Two support rods are provided between the cutting ropes and the connecting plates, and the two support rods are respectively connected to the two ends of the cutting ropes. The connecting plates are mounted on the bases. Control components are provided between the connecting plates and the bases to control the position of the connecting plates relative to the bases. Tensioning components are provided between the ends of the support rods and the cutting ropes. The two tensioning components at both ends of the cutting ropes cooperate to straighten the cutting ropes.

[0004] Although the aforementioned patent incorporates a control component that controls the position of the connecting plate relative to the base, thereby controlling the position of the cutting rope relative to the base and facilitating the adjustment of the relative distance between the two cutting ropes, thus enhancing the flexibility of the device and expanding its applicability to process raw materials of different widths, it lacks a mechanism for positioning the concrete brick blank. This can lead to inaccurate alignment of the cutting lines, affecting cutting precision and dimensional consistency, and ultimately reducing the quality of the concrete brick.

[0005] Therefore, this utility model provides a side-cutting device for concrete brick blanks to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] This utility model provides a device for trimming the side of concrete brick blanks, such as... Figures 1-5 As shown, a side-cutting device for concrete brick blanks includes a base plate 1, a vertical plate 2 fixedly connected to one side of the upper surface of the base plate 1, a driving component fixedly installed on the upper surface of the vertical plate 2, a support frame 15 fixedly connected to the top of one side of the vertical plate 2, and a cutting component fixedly connected to the upper surface of the support frame 15.

[0028] The drive assembly includes a motor 3, the lower surface of which is fixedly mounted on the upper surface of the vertical plate 2. A threaded rod 4 is fixedly connected to the output end of the motor 3. A sliding block 5 is threadedly connected to the outer surface of the threaded rod 4. A connecting rod 6 is rotatably connected to one side of the sliding block 5. A gear 7 is fixedly connected to one end of the connecting rod 6. A guide rod 8 is slidably connected to the outer surface of the gear 7. A tooth 9 that matches the gear 7 is provided at the top of the side of the guide rod 8 that is in contact with the gear 7. A positioning component is fixedly connected to the middle of the outer surface of the connecting rod 6. Starting the motor 3 can drive the threaded rod 4 to rotate, so that the sliding block 5 slides on its surface. The gear 7 can be driven up and down through the connecting rod 6 to perform a punching cut with the cutting line 19, which can improve the cutting efficiency. At the same time, when the gear 7 moves to the top of the guide rod 8 and meshes with the tooth 9, the gear 7 can drive the placement plate 10 to rotate and flip through the connecting rod 6, which facilitates the rapid unloading of the cut concrete brick blanks, reduces manual intervention, reduces the labor intensity of operators, and effectively improves the overall production efficiency.

[0029] The positioning assembly includes a placement plate 10, the middle of which is fixedly connected to the middle of the outer surface of the connecting rod 6. An electric push rod 11 is fixedly connected to the inner wall of the placement plate 10. A positioning plate 12 is fixedly connected to one end of the electric push rod 11. A protrusion is provided in the middle of the upper surface of the positioning plate 12. After the concrete brick blank is placed on the placement plate 10, the electric push rod 11 can be activated to push the positioning plate 12 to position the concrete brick blank in the middle of the placement plate 10, so as to correspond to the position of the cutting line 19. This ensures that the cutting line 19 can accurately cut and trim the side of the concrete brick blank, ensuring the cutting accuracy and dimensional consistency, thereby improving the processing quality of the concrete brick. The protrusion can also be used to move the moving frame 18 to adjust the distance between the two cutting lines 19, so that the cutting line 19 can trim the edges of concrete brick blanks of different sizes.

[0030] A limiting rod 13 is fixedly connected to the other side of the upper surface of the base plate 1. A guide groove adapted to the connecting rod 6 is opened in the middle of one side of the limiting rod 13. Limiting strips 14 are fixedly connected to both sides of the inner wall of the guide groove. A groove adapted to the limiting strip 14 is opened at one end of the outer surface of the connecting rod 6. The limiting strip 14 can limit and guide the connecting rod 6 to ensure that it is in a vertical movement state when it moves at the bottom of the guide rod 8, and avoids it from rotating on its own.

[0031] The cutting assembly includes a cylinder 16, the lower surface of which is fixedly mounted on the upper surface of the support frame 15. The output end of the cylinder 16 is fixedly connected to a mounting plate 17. Slide grooves are provided on both sides of the upper surface of the mounting plate 17. Moving frames 18 are slidably connected to both sides inside the slide grooves. A cutting line 19 is fixedly connected inside the moving frames 18. When the cylinder 16 is activated, it can push the mounting plate 17 downward. Under the limitation of the protrusion, the moving frames 18 can move towards each other inside the slide grooves to trim the concrete brick blanks of different sizes through the cutting line 19.

[0032] Telescopic rods 20 are fixedly connected to opposite sides of the two movable frames 18. Springs 21 are sleeved on the outer surface of the telescopic rods 20. When the movable frames 18 move towards each other, the springs 21 are squeezed. The telescopic rods 20 can prevent the springs 21 from bending. Thus, the springs 21 can push the movable frames 18 outward through their rebound force to ensure the symmetry and stability of the positions of the two movable frames 18.

[0033] Working steps: First, after placing the concrete brick blank on the placement plate 10, start the motor 3 to drive the threaded rod 4 to rotate, so that the sliding block 5 slides on its surface. The connecting rod 6 drives the gear 7 to move upward to a certain position. Then, start the cylinder 16 to push the mounting plate 17 downward to a certain position. Then, start the electric push rod 11 to push the positioning plate 12 to position the concrete brick blank. At the same time, the protrusion can move the moving frame 18 to adjust the distance between the cutting lines 19 on both sides. The rebound force of the spring 21 can push the moving frame 18 outward. Pushing the telescopic rod 20 prevents the spring 21 from bending, ensuring that the positions of the two moving frames 18 are symmetrical. Next, the mounting plate 17 moves the cutting line 19 downward, and the placement plate 10 moves the concrete brick blank upward to perform a punching cut on the concrete brick blank. Finally, the mounting plate 17 moves upward to the inner top wall of the support frame 15, and the placement plate 10 continues to move upward, so that the gear 7 moves to the top of the guide rod 8. When it meshes with the teeth 9, the gear 7 can drive the placement plate 10 to rotate and flip through the connecting rod 6, and then the positioning plate 12 moves outward to quickly unload the concrete brick blank.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
