Description

Technical Field

[0001] This utility model relates to the field of waste sand separation technology, and more specifically, to an automatic waste sand separation mechanism for a brick pressing and molding machine. Background Technology

[0002] A brick pressing and molding machine is a mechanical device specifically used to press raw materials for brick and tile production into brick blanks of specific shapes and sizes under high pressure. The waste sand automatic separation mechanism mainly separates waste sand from the material through vibration, thereby ensuring the quality of the finished bricks.

[0003] The waste sand automatic separation mechanism of common brick pressing and molding machines can only separate materials by vibration, but lacks the function of uniform material distribution. In actual operation, the separated material falls directly into the pressing tank to wait for pressing. Due to the difference in the trajectory of the material falling after separation, the amount of material received by different areas inside the pressing tank is not equal. As a result, the overall density of the material after the pressing and molding process is inconsistent, which ultimately leads to a decline in the quality of the finished product.

[0004] In summary, to ensure the quality of the finished product, it is necessary to solve the problem of the material not being evenly spread after separation, so that the material can be evenly spread in the pressing tank during the separation process. Utility Model Content

[0005] The problem to be solved by the automatic waste sand separation mechanism of the brick pressing and molding machine provided by this utility model is that the trajectory of the falling material is different, which leads to the uneven amount of material received by different areas inside the pressing tank. After the material is pressed and molded, its overall density is inconsistent.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic waste sand separation mechanism for a brick pressing and molding machine, comprising a worktable, multiple pressing grooves on the worktable, a pressing mechanism on the worktable, a separation box installed at the upper end of the worktable, a separation drum inside the separation box, multiple separation grooves on the outer side of the separation drum, a power mechanism on the separation box, four support legs installed on the surface of the separation box, the lower ends of the support legs connected to the worktable, an installation frame installed at the upper end of the separation box, a first motor installed on the surface of the installation frame, a lead screw installed at the output end of the first motor, a drive frame threadedly connected to the outer side of the lead screw, a receiving hopper installed on the inner side of the drive frame, a feeding frame installed at the lower end of the receiving hopper, and the first motor used to control the rotation of the lead screw.

[0007] In a preferred embodiment, a power mechanism is used to provide a rotational driving force to the separating drum. The power mechanism includes a linkage component and a support component.

[0009] In a preferred embodiment, the support assembly includes an inner support plate installed inside the separation chamber, an outer support plate installed inside the separation chamber, a first connecting ring installed outside the separation drum, and a second connecting ring installed outside the separation drum. The first connecting ring is rotatably connected to the inner support plate, and the second connecting ring is rotatably connected to the outer support plate.

[0010] In a preferred embodiment, the pressing mechanism is used to press and shape the material. The pressing mechanism includes an ejector assembly and a pressing assembly. The ejector assembly is used to eject the pressed and shaped material from the inside of the pressing groove, and the pressing assembly is used to press and shape the material in the pressing groove.

[0011] In a preferred embodiment, the top material assembly includes a support frame mounted on the lower end of the worktable, a first hydraulic cylinder mounted on the surface of the support frame, and a plurality of lower support blocks mounted on the output end of the first hydraulic cylinder.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6The waste sand automatic separation mechanism of the brick pressing and molding machine includes a worktable 1, on which multiple pressing grooves 11 are opened, and a pressing mechanism is set on the worktable 1. A separation box 12 is installed at the upper end of the worktable 1. A separation drum 20 is set inside the separation box 12. Multiple separation grooves 21 are opened on the outer side of the separation drum 20. A power mechanism is set on the separation box 12. Four support legs 13 are installed on the surface of the separation box 12. The lower ends of the support legs 13 are connected to the worktable 1. An installation frame 14 is installed at the upper end of the separation box 12. A first motor 15 is installed on the surface of the installation frame 14. A lead screw 16 is installed at the output end of the first motor 15. A drive frame 17 is threadedly connected to the outer side of the lead screw 16. A receiving hopper 18 is installed on the inner side of the drive frame 17. A feeding frame 19 is installed at the lower end of the receiving hopper 18. The first motor 15 is used to control the rotation of the lead screw 16.

[0025] It should be noted that the material separated from the separating drum 20 falls downward into the receiving hopper 18, while the material in the receiving hopper 18 slides into the feeding frame 19. At the same time, the first motor 15 drives the lead screw 16 to rotate in the forward direction. The lead screw 16 drives the receiving hopper 18 and the feeding frame 19 to move towards the pressing groove 11 through the drive frame 17. At this time, the feeding frame 19 slides along the surface of the workbench 1 until the feeding frame 19 passes above the pressing groove 11, at which point the material in the feeding frame 19 falls downward and spreads flat inside the pressing groove 11.

[0026] It is worth noting that when the receiving hopper 18 moves toward the pressing trough 11, since its planar area is larger than the planar area of ​​the bottom of the separating box 12, it does not affect the receiving hopper 18 from receiving the falling material.

[0027] Refer to the instruction manual appendix Figures 2 to 6 The power mechanism is used to provide rotational driving force to the separating drum 20. The power mechanism includes a linkage component and a support component. The output end of the linkage component is connected to the separating drum 20. The linkage component is used to control the rotational movement of the separating drum 20. The support component is used to support the separating drum 20 when it is rotating or stationary.

[0028] It should be noted that the power mechanism achieves uniform rotation of the separation drum 20 through meshing transmission. Its rotation speed is precisely controlled by the second motor 323 to ensure that the waste sand separation efficiency matches the material processing volume. The centrifugal force of the rotation of the separation drum 20 causes fine particles of waste sand to be thrown out through the separation tank 21, while qualified brick materials are retained in the drum due to their larger particle size.

[0029] Refer to the instruction manual appendix Figure 5The linkage assembly includes multiple teeth 321 installed on the outside of the separating drum 20, a mounting plate 322 installed inside the separating box 12, a second motor 323 installed on the surface of the mounting plate 322, and a gear 324 installed on the output end of the second motor 323. The gear 324 meshes with the multiple teeth 321, and the second motor 323 is used to control the rotational movement of the gear 324.

[0030] It should be noted that the second motor 323 drives the gear 324 to rotate, and the gear 324 drives the separation drum 20 to rotate because it meshes with the teeth 321.

[0031] Refer to the instruction manual appendix Figures 4 to 5 The support assembly includes an inner support plate 311 installed inside the separation box 12, an outer support plate 312 installed inside the separation box 12, a first connecting ring 313 installed outside the separation drum 20, and a second connecting ring 314 installed outside the separation drum 20. The first connecting ring 313 is rotatably connected to the inner support plate 311, and the second connecting ring 314 is rotatably connected to the outer support plate 312.

[0032] It should be noted that the inner support plate 311 and the outer support plate 312 form a double bearing support structure. The first connecting ring 313 and the inner support plate 311 cooperate to bear the radial force, and the second connecting ring 314 and the outer support plate 312 cooperate to bear the axial load, ensuring the stability of the drum operation.

[0033] Refer to the instruction manual appendix Figures 1 to 3 The pressing mechanism is used to press and shape the material. The pressing mechanism includes a top material assembly and a pressing material assembly. The top material assembly is used to push the pressed and shaped material out of the inside of the pressing groove 11, and the pressing material assembly is used to press and shape the material in the pressing groove 11.

[0034] It should be noted that the top material assembly and the pressing material assembly are driven by independent hydraulic systems, and the lifting speed is controlled by a proportional valve to avoid cracking due to impact when the brick blank is pushed out or pressed.

[0035] It is worth noting that multiple pressing blocks 423 move synchronously through a rigid linkage frame, ensuring that the pressing force is distributed with minimal deviation in each area of ​​the pressing groove 11, thus fundamentally solving the problem of uneven brick density.

[0036] Refer to the instruction manual appendix Figure 3 The top material assembly includes a support frame 411 installed at the lower end of the workbench 1, a first hydraulic cylinder 412 installed on the surface of the support frame 411, and a plurality of lower support blocks 413 installed at the output end of the first hydraulic cylinder 412. The lower support blocks 413 are inserted into the interior of the pressing groove 11, and the first hydraulic cylinder 412 is used to control the lifting and lowering movement of the lower support blocks 413.

[0037] It should be noted that after the material is pressed and formed, the lower support block 413 is driven to move upward by the first hydraulic cylinder 412 until the lower support block 413 pushes the pressed and formed material out of the pressing groove 11.

[0038] Refer to the instruction manual appendix Figure 3 The pressing assembly includes a support frame 421 mounted on the upper end of the workbench 1, a second hydraulic cylinder 422 mounted on the surface of the support frame 421, and a plurality of pressing blocks 423 mounted on the output end of the second hydraulic cylinder 422. The second hydraulic cylinder 422 is used to control the lifting and lowering movement of the pressing blocks 423.

[0039] It should be noted that the lower pressing block 423 is moved downward by the second hydraulic cylinder 422 until it is inserted into the pressing groove 11. At this time, the material is pressed into shape by the cooperation of the lower pressing block 423 and the lower support block 413.

[0040] Refer to the instruction manual appendix Figure 2 The separation box 12 is provided with a feeding and discharging assembly, which is used to allow materials to enter or exit the separation box 12. The feeding and discharging assembly includes a receiving box 511 installed on the surface of the separation box 12 and a feeding port 512 opened on the surface of the separation box 12.

[0041] It should be noted that the material is added into the interior of the separating drum 20 through the feed inlet 512. After the separating drum 20 separates the material, the waste sand rolls along its inner wall toward the receiving box 511 until the waste sand is discharged into the interior of the receiving box 511.

[0042] Working principle: Material enters the rotating separating drum 20 through the feed inlet 512 of the separating box 12. The second motor 323 in the power mechanism drives the gear 324 to rotate. Through meshing with the outer teeth 321 of the separating drum 20, the separating drum 20 rotates at a constant speed. The inner support plate 311 in the support assembly supports the separating drum 20 through the first connecting ring 313, and the outer support plate 312 supports the separating drum 20 through the second connecting ring 314, ensuring the stable operation of the separating drum 20. Under the action of centrifugal force, the waste sand in the material is thrown out through the separation groove 21 on the surface of the separating drum 20 and slides into the receiving box 511 along the inner wall of the separating drum 20 to complete the separation. The qualified brick material falls from the separating box 12. The falling material first enters the receiving hopper 18, and the first motor 15 drives the lead screw 16 to rotate. The threaded drive frame 17 drives the receiving hopper 18 and the feeding frame 19 below to move back and forth along the surface of the workbench 1. The material flows continuously from the receiving hopper 18 into the feeding frame 19. When the feeding frame 19 passes above the pressing groove 11 on the workbench 1, the material is evenly spread into the pressing groove 11 through the bottom opening of the feeding frame 19, eliminating the unevenness of the material due to the difference in the falling trajectory. After the material is spread, the pressing component is started. The second hydraulic cylinder 422 on the support frame 421 pushes multiple lower pressing blocks 423 to move down synchronously, insert them into the pressing groove 11 and apply high pressure to the material, so that the material is pressed and formed between the pressing groove 11 and the bottom support block 413. After forming, the top material component works. The first hydraulic cylinder 412 on the support frame 411 pushes the lower support block 413 to the top, and smoothly pushes the brick blank out of the pressing groove 11 to complete the demolding.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
