Description

Technical Field

[0001] This utility model relates to the field of billet storage machine technology, and in particular to a billet storage machine for a slab manufacturing line. Background Technology

[0002] In the field of modern building decoration materials, sintered stone slabs have gradually become a market favorite due to their excellent properties such as high strength, wear resistance, and environmental friendliness, and are widely used in home countertops, wall decorations, and other scenarios. During the sintered stone slab manufacturing process, the blank storage machine, as an indispensable intermediate link in the production line, directly affects the continuity of sintered stone slab production and the quality of the finished product. It is responsible for the temporary storage and transfer of formed stone blanks, ensuring that the blanks can accurately and stably enter subsequent processing steps such as cutting and polishing, and is a key piece of equipment for ensuring the efficient operation of sintered stone slab manufacturing.

[0003] Currently, most common slab manufacturing lines use traditional, fixed-size clamping mechanisms and simple conveying systems for their billet storage machines. The clamping mechanism typically consists of fixed-size grippers that are closed by a cylinder to secure the billet. The conveying system relies on a motor-driven conveyor belt to move the billet horizontally. Its working principle is based on a preset mechanical motion pattern, with a control system uniformly scheduling the clamping and conveying actions to transfer the billet from the storage area to the processing area. This design is relatively simple, low-cost, and can meet basic production needs when the billet dimensions are uniform.

[0004] However, in actual production, due to factors such as raw material ratios, mold differences, and fluctuations in molding processes, the shape, size, and surface texture of stone blanks often vary significantly. Traditional blank storage machines with fixed-specification grippers cannot adaptively adjust to the actual shape of the stone blanks, easily leading to uneven clamping force or clamping position deviations during the clamping process. For stone blanks that are too large or irregularly shaped, the grippers cannot fully fit, resulting in unstable clamping; while for stone blanks with special surface textures, rigid clamping causes surface scratches. During the stone blank transfer process, these unstable factors easily cause the stone blanks to break or have edge damage, significantly increasing the scrap rate. This not only increases production costs but also severely restricts the production efficiency and product quality stability of the slab manufacturing line. Therefore, a blank storage machine for slab manufacturing lines is proposed to solve these problems. Utility Model Content

[0038] The driving assembly includes a first hydraulic cylinder 7, which works in conjunction with a moving block 8 to perform vertical reciprocating motion. Through a four-bar linkage formed by a connecting rod 9 and a first rotating plate 10, it drives the clamping rods 13 on both sides to converge towards the center simultaneously, achieving flexible clamping of the stone blank and avoiding surface damage caused by rigid contact. The top of the first hydraulic cylinder 7 is fixedly connected to the bottom of the first support plate 11. The output end of the first hydraulic cylinder 7 is fixedly connected to the moving block 8. The bottom of the moving block 8 is fixedly connected to the clamping rod 13.

[0039] Reference Figure 1 , Figure 5 and Figure 6 A second support plate 14 is fixedly connected to the bottom of the first conveyor belt 3, and a second hydraulic cylinder 15 is fixedly connected to the top of the second support plate 14. The second hydraulic cylinder 15 drives the inclined support plate 16 to slide along the second support plate 14. Through the contact between the inclined surface and the rotating wheel 17, the horizontal thrust is converted into the rotational motion of the rotating wheel 17, which drives the hollow plate 18 and the sliding column 23 to rise vertically, so as to lift the stone billet to the height of the second conveyor belt 5. The output end of the second hydraulic cylinder 15 is fixedly connected to the inclined support plate 16, and the bottom of the inclined support plate 16 is slidably connected to the top of the second support plate 14. The side wall of the inclined support plate 16 is provided with a rotating wheel 17. A hollow plate 18 is rotatably connected to the side wall of wheel 17.

A first spring 20 is provided on the outer wall of the sliding column 23. One end of the first spring 20 is fixedly connected to the outer wall of the sliding column 23, and the other end of the first spring 20 is fixedly connected to the top of the first connecting plate 19. An L-shaped connecting plate 21 is fixedly connected to the top of the sliding column 23. The side wall of the L-shaped connecting plate 21 is provided on the side wall of the second conveyor belt 5.

[0040] Reference Figure 1 , Figure 7 and Figure 8The outer wall of the mobile platform 2 is provided with a parallel moving structure 25. A motor 24 is fixedly connected to the top of the parallel moving structure 25. The motor 24 drives the rotating shaft 26 to rotate. Through the crank-slider mechanism composed of the second rotating plate 28, the third rotating plate 29 and the sliding plate 30, the rotational motion is converted into the vertical reciprocating motion of the sliding plate 30, which adjusts the height of the stone blank in real time to meet the stacking requirements of stone blanks of different thicknesses. The output end of the motor 24 is fixedly connected to the rotating shaft 26. The top of the parallel moving structure 25 is fixedly connected to the third support plate 27. The interior of the third support plate 27 is rotatably connected to the outer wall of the rotating shaft 26. The side wall of the third support plate 27 is rotatably connected to the second rotating plate 28. The side wall of the second rotating plate 28 is rotatably connected to the third rotating plate 29. The side wall of the third rotating plate 29 is rotatably connected to the first connecting block 31. The top of the first connecting block 31 is fixedly connected to the sliding plate 30. The top of the sliding plate 30 is fixedly connected to the fixed frame 32. The side wall of the fixed frame 32 is set on the side wall of the first conveyor belt 3.

[0041] Working Principle: When using the billet storage machine in the slab manufacturing line, the first hydraulic cylinder 7 is activated when the billet is transported to the storage area via the first conveyor belt 3. Its piston rod pushes the moving block 8 to move vertically. The moving block 8 is hinged to the first rotating plate 10 via the connecting rod 9, forming a four-bar linkage. Under the thrust of the first hydraulic cylinder 7, the moving blocks 8 on both sides converge towards the center, driving the clamping rod 13 to flexibly clamp the billet. During clamping, the suction cup 12 is activated, using negative pressure to adhere to the surface of the billet, offsetting the lateral extrusion force of the clamping rod 13, preventing damage to the billet surface due to excessive clamping, and ensuring the billet is centered, achieving an adaptive clamping effect.

[0042] Subsequently, the second hydraulic cylinder 15 drives the inclined support plate 16 to slide along the second support plate 14. The inclined surface of the inclined support plate 16 contacts the rotating wheel 17, converting the horizontal thrust into the rotational motion of the rotating wheel 17, which is then transmitted to the sliding column 23 through the hollow plate 18 and the first connecting plate 19. The sliding column 23 rises vertically along the support frame 22, driving the L-shaped connecting plate 21 to lift the stone blank to the height of the second conveyor belt 5. Then, by reducing damage to the stone blank during the clamping process, the effect of lifting the stone blank is achieved.

[0043] The motor 24 drives the rotating shaft 26 to rotate. Through the crank-slider mechanism composed of the second rotating plate 28, the third rotating plate 29 and the sliding plate 30, the rotational motion is converted into the vertical reciprocating motion of the sliding plate 30. The sliding plate 30 is linked with the first conveyor belt 3 through the first connecting block 31, and the layer height of the fixed frame 32 is adjusted in real time to ensure that the stone blanks are evenly stressed when stacked on the storage rack 1, thus achieving the effect of stable storage of stone blanks.
