Description

Technical Field

[0001] The utility model relates to the field of hollow brick production, in particular to an auxiliary demoulding device for hollow brick production. Background Art

[0002] In the field of building materials, as an energy-saving and environment-friendly building material, hollow bricks are widely used in various building structures such as walls and partitions due to their advantages of light weight, excellent heat insulation performance, and convenient construction, effectively promoting the sustainable development of the building industry. The production process of hollow bricks mainly includes key steps such as raw material preparation, mixing, pressing and forming, and demoulding. Among them, demoulding, as a key link after forming, directly affects the quality and production efficiency of hollow bricks.

[0003] The patent document with the publication number of CN218255741U discloses a hollow brick forming machine that is easy to disassemble and assemble. The device innovatively designs a set of forming components. This component can not only accurately complete the pressing work of hollow bricks, but also cleverly utilize the downward movement of the upper part of the pressing block to form an upward ejection force in the cavity, so that the hollow bricks can be smoothly ejected from the mold after pressing, effectively solving the problems of poor demoulding effect and low efficiency in the traditional demoulding method.

[0004] However, although such a design improves the demoulding efficiency and stability to a certain extent, the demoulding process highly depends on the precise cooperation between the lifting mechanism and the pressing cylinder. In actual operation, it is necessary to ensure that the speed at which the first cylinder drives the pressing block to move downward is exactly the same as the speed at which the lifting mechanism moves upward to ensure the smooth progress of the demoulding action. However, due to the complexity of the mechanical system and the uncertainty of the operating environment, it is often difficult to maintain this precise synchronization for a long time. Once the speeds of the two do not match, abnormal situations such as impact and jamming may occur during the demoulding process, leading to quality problems such as damage to hollow bricks and a decrease in dimensional accuracy. Summary of the Utility Model

[0005] In order to overcome the shortcoming of insufficient stability, the utility model provides a stable auxiliary demoulding device for hollow brick production.

Those of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", etc. are used to describe the drawings and do not represent a limitation on the scope of the present utility model as defined by the appended claims.

[0019] Embodiment: An auxiliary demolding device for the production of hollow bricks, as Figures 1 - 3 shown, includes a mounting frame 1, a horizontal cylinder 101, a support frame 102, a mold 103, a vertical cylinder 2 and a pushing block 201. Horizontal cylinders 101 are installed on both the left and right sides of the top of the mounting frame 1. The horizontal cylinders 101 are connected to the support frame 102 to push the support frame 102 to move back and forth. Vertical cylinders 2 are installed on both the left and right sides of the support frame 102. The lower ends of the vertical cylinders 2 are connected to the pushing block 201. A mold 103 is placed on the mounting frame 1. The pushing block 201 cooperates with the mold 103. It also includes a servo motor 3, a lead screw 4, a limiting rod 5 and a stable conveying assembly. The servo motor 3 is installed on the support frame 102. The servo motor 3 is connected to the lead screw 4. The lead screw 4 passes through the bottom of the support frame 102 and is threadedly connected to the mold 103. The upper end of the limiting rod 5 is connected to the bottom of the support frame 102. The mold 103 is slidably connected to the limiting rod 5. A stable conveying assembly for assisting in moving the mold 103 is provided on the mounting frame 1. The mold 103 is placed on the stable conveying assembly. After the mold 103 is loaded with materials, the vertical cylinder 2 pushes the pushing block 201 downward to form the hollow brick. Subsequently, the horizontal cylinder 101 pushes the support frame 102 to move, so that all the components connected to the support frame 102 move together, and the mold 103 also moves on the stable conveying assembly. When the mold 103 passes through the stable conveying assembly, the servo motor 3 is turned on, and the mold 103 is driven to move upward by the lead screw 4. The pushing block 201 pushes out the formed hollow brick to complete the discharging. Subsequently, all the components are reset.

[0020] As Figure 1 and Figure 3As shown, the stable conveying assembly includes a vertical bearing 6, a roller 7, a conveyor belt 8 and a support plate 9. Vertical bearings 6 are connected to the left and right sides of the middle of the mounting frame 1. A roller 7 is rotatably connected between the vertical bearings 6. The rollers 7 are respectively located at the front and rear ends of the middle of the mounting frame 1. A conveyor belt 8 is sleeved between the front and rear rollers 7. A support plate 9 is connected to the middle of the mounting frame 1. The conveyor belt 8 is sleeved on the support plate 9. When the mold 103 moves, the bottom of the hollow brick also contacts the conveyor belt 8, thereby driving the conveyor belt 8 to move together. The conveyor belt 8 rotates on the rollers 7 to support the hollow brick.

[0021] As Figure 1 shown, it further includes a longitudinal coating 10. The inner side of the mold 103 is evenly coated with the longitudinal coating 10, which is used to assist the discharge of the hollow brick.

[0022] As Figure 1 shown, it further includes a collection box 11. The collection box 11 is placed in the middle of the mounting frame 1.

[0023] As Figure 1 shown, it further includes an adapter plate 12. The adapter plate is connected to the end of the mounting frame 1, and the adapter plate 12 contacts the conveyor belt 8.

[0024] As Figure 1 shown, it further includes a protective sleeve 13. A telescopic protective sleeve 13 is connected between the support frame 102 and the mold 103, and the protective sleeve 13 covers the lead screw 4 and the limit rod 5.

[0025] A feeding device is connected to the mounting frame 1 to perform quantitative feeding on the mold 103. After the mold 103 is fed, the longitudinal cylinder 2 is activated. The longitudinal cylinder 2 pushes the pushing block 201 downward. The pushing block 201 cooperates with the mold 103 to extrude the raw materials in the mold 103 into a preset shape and gradually set. Subsequently, the transverse cylinder 101 is activated. The transverse cylinder 101 pushes the support frame 102 to move. All the components connected to the support frame 102 move together. The mold 103 and the pushing block 201 extrude the hollow brick and drive the conveyor belt 8 together. The conveyor belt 8 rotates around the idler roller 7, and the bottom of the hollow brick will not be subject to friction. When the hollow brick detaches from the conveyor belt 8, the bottom contacts the subsequent placing mechanism, facilitating subsequent air drying or drying. At this time, the servo motor 3 is activated. The servo motor 3 drives the lead screw 4 to rotate. The lead screw 4 cooperates with the mold 103 to pull the mold 103 upward. Moreover, the top of the hollow brick is extruded by the pushing block 201, and the pushing block 201 remains stationary. The hollow brick cannot move with the mold 103 and gradually detaches from the mold 103. After the mold 103 moves upward, the hollow brick detaches from the mold 103. At this time, the servo motor 3 reverses, and the mold 103 moves downward to push the hollow brick away from the pushing block 201. Subsequently, the mold 103 completely moves upward away from the hollow brick. During the process of the longitudinal cylinder 2 pulling the pushing block 201 upward, it performs a short up-and-down vibration to prevent any remaining hollow bricks from sticking to the pushing block 201. After the discharging is completed, the transverse cylinder 101 is activated to pull the support frame 102 backward to reset. During this period, the servo motor 3 and the longitudinal cylinder 2 respectively reset the mold 103 and the pushing block 201 to perform the next feeding;

[0026] When the mold 103 detaches from the hollow brick, the longitudinal coating 10 can effectively protect the surface quality of the hollow brick. When the front end of the conveyor belt 8 passes through the connecting plate 12, the hollow brick and the conveyor belt 8 can be separated, so that when the hollow brick detaches from the conveyor belt 8, it will not pull the conveyor belt 8, protecting the conveyor belt 8. At the same time, it can remove the brick raw materials sticking to the surface of the conveyor belt 8. The waste removed is swept into the collection boxes 11 on both sides by the staff. The protective sleeve 13 can protect the lead screw 4, thus effectively extending the service life of the lead screw 4.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes can be made therein without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
