Description

Technical Field

[0001] This invention relates to the field of zeolite molecular sieve technology, specifically to an automatic forming and cutting production line for zeolite molecular sieves. Background Technology

[0002] Zeolite molecular sieves, as a type of aluminosilicate crystal with microporous (pore size <2nm) structure, are widely used in catalysis, adsorption and separation, ion exchange and other fields.

[0003] Zeolite molecular sieve products are produced as wet blanks. During the transportation process, the honeycomb pores are in a transverse plane. Zeolite molecular sieves have a high composition, strong clay toughness, and poor support. The characteristic of this transportation state is that the transverse plane cannot be subjected to force for a long time. Due to the small support force of the transverse plane, the honeycomb pore end face will deform and sink after a short time when it is placed transversely in the wet blank state, which will greatly affect the production efficiency of the product. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems, thereby providing an automatic forming and cutting production line for zeolite molecular sieves;

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] This invention provides an automated forming and cutting production line for zeolite molecular sieves.

[0007] The device includes a material preparation device, a first cutting device, a first conveying device, a second cutting mechanism, a tilting mechanism, and a second conveying mechanism. The material preparation device is located on one side of the first cutting device and is used to produce wet zeolite molecular sieve blanks. The first cutting device is used to cut the wet zeolite molecular sieve blanks produced by the material preparation device. The feed end of the first conveying device is located on the other side of the first cutting device and is used to convey the wet zeolite molecular sieve blanks cut by the first cutting device. The second cutting mechanism is located at the discharge end of the first conveying device and is used to perform secondary cutting on the wet zeolite molecular sieve blanks on the first conveying device. The tilting mechanism is located on one side of the second cutting mechanism and is used to rotate the wet zeolite molecular sieve blanks cut by the second cutting mechanism 90 degrees clockwise, thereby turning the honeycomb pores on the wet zeolite molecular sieve blanks from the horizontal direction to the vertical direction. The feed end of the second conveying mechanism is located on one side of the tilting mechanism and is used to convey the wet zeolite molecular sieve blanks rotated by the tilting mechanism.

[0008] Optionally, the flipping mechanism includes a fixed support, a flipping platform, and a flipping plate. The flipping platform is mounted on the fixed support, and the flipping plate is mounted on the flipping platform. A flipping cylinder is mounted on the flipping platform to drive the flipping plate to flip 90 degrees clockwise. When the wet zeolite molecular sieve on the first conveying device comes into contact with the surface of the flipping plate, the second cutting mechanism cuts the wet zeolite molecular sieve on the first conveying device to form a single zeolite molecular sieve. After the second cutting mechanism finishes cutting, it immediately resets. At this time, the flipping cylinder drives the flipping plate and the single zeolite molecular sieve on the flipping plate to flip 90 degrees clockwise synchronously. A pushing cylinder is mounted on the flipping plate to push the single zeolite molecular sieve on the flipped plate to the second conveying mechanism.

[0009] Optionally, the fixed support is further provided with a feeding mechanism, which includes a feeding bracket, a conveyor chain, and a conveyor motor. The feeding bracket is mounted on the conveyor chain, and the feeding brackets are configured in several groups, with evenly spaced intervals between them. Several sets of pallets are arranged inside the feeding bracket from top to bottom. The fixed support is also provided with a lifting mechanism, which is used to lift the pallets inside the feeding mechanism one by one.

[0010] The flipping platform is equipped with a pushing mechanism, which is used to push the pallets on the feeding mechanism one by one onto the flipping platform. The surface of a single zeolite molecular sieve cut by the second cutting mechanism is attached to the pallet. The pushing cylinder is used to push the pallet and the single zeolite molecular sieve on the pallet together onto the second conveying mechanism. After the pallets on the flipping platform are pushed, the pushing mechanism sequentially replenishes the pallets on the feeding bracket onto the flipping platform.

[0011] Optionally, the pushing mechanism includes a pushing platform and a pushing cylinder. The pushing platform has a groove that is adapted to the pallet. The lifting mechanism includes a screw and a linear motor. The lower end of the screw is connected to the linear motor. The linear motor drives the screw to move up and down, so that the screw lifts the pallets in the feeding mechanism one by one from bottom to top.

[0012] Optionally, the feeding bracket includes a feeding base and limiting rods. The limiting rods are configured in several groups, and the groups of limiting rods are vertically arranged on the side wall of the feeding base.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1-3 As shown, this invention provides an automated forming and cutting production line for zeolite molecular sieves.

[0023] The system includes a material preparation device 1, a first cutting device 2, a first conveying device 3, a second cutting mechanism 4, a tilting mechanism 5, and a second conveying mechanism 6. The material preparation device 1 is located on one side of the first cutting device 2 and is used to produce wet zeolite molecular sieve blanks. The first cutting device 2 is used to cut the wet zeolite molecular sieve blanks produced by the material preparation device 1. The feed end of the first conveying device 3 is located on the other side of the first cutting device 2, and the first conveying device 3 is used to convey the wet zeolite molecular sieve blanks cut by the first cutting device 2. The second cutting mechanism 4 is located on the other side of the material preparation device 2. The discharge end of the first conveying device 3 is provided. The second cutting mechanism 4 is used to perform secondary cutting on the wet zeolite molecular sieve blank on the first conveying device 3. The flipping mechanism 5 is located on one side of the second cutting mechanism 4. The flipping mechanism 5 is used to flip the wet zeolite molecular sieve blank cut by the second cutting mechanism 4 clockwise by 90 degrees, thereby turning the honeycomb pores on the wet zeolite molecular sieve blank from the horizontal direction to the vertical direction. The feed end of the second conveying mechanism 6 is located on one side of the flipping mechanism 5. The second conveying mechanism 6 is used to convey the wet zeolite molecular sieve blank after it has been turned by the flipping mechanism 5.

[0024] The flipping mechanism 5 includes a fixed support 7, a flipping platform 8, and a flipping plate 9. The flipping platform 8 is mounted on the fixed support 7, and the flipping plate 9 is mounted on the flipping platform 8. A flipping cylinder 10 is mounted on the flipping platform 8. The flipping cylinder 10 is used to drive the flipping plate 9 to flip 90 degrees clockwise. When the wet zeolite molecular sieve on the first conveying device 3 comes into contact with the surface of the flipping plate 9, the second cutting mechanism 4 cuts the wet zeolite molecular sieve on the first conveying device 3 to form a single zeolite molecular sieve. After the second cutting mechanism 4 finishes cutting, it immediately resets. At this time, the flipping cylinder 10 drives the flipping plate 9 and the single zeolite molecular sieve on the flipping plate 9 to flip 90 degrees clockwise in sync. A pushing cylinder is mounted on the flipping plate 9. The pushing cylinder is used to push the single zeolite molecular sieve on the flipping plate 9 after it has been flipped to the second conveying mechanism 6.

[0025] The fixed support 7 is also provided with a feeding mechanism 11, which includes a feeding bracket, a conveyor chain 12, and a conveyor motor. The feeding bracket is set on the conveyor chain 12 and is configured in several groups. The feeding brackets are evenly spaced apart. Several sets of pallets 17 are arranged from top to bottom inside the feeding bracket. The fixed support 7 is also provided with a lifting mechanism 13, which is used to lift the pallets 17 in the feeding mechanism 11 one by one, thereby realizing the function of automatic feeding, reducing the frequent operation of workers, and improving the production efficiency of enterprises.

[0026] The flipping platform 8 is equipped with a pushing mechanism, which pushes the pallets 17 on the feeding mechanism 11 one by one onto the flipping plate 9. The surface of the individual zeolite molecular sieves cut by the second cutting mechanism 4 is attached to the pallet 17. The pushing cylinder pushes the pallet 17 and the individual zeolite molecular sieves on the pallet 17 together onto the second conveying mechanism 6. After the pallets 17 on the flipping plate 9 are pushed, the pushing mechanism sequentially replenishes the pallets 17 on the feeding bracket onto the flipping plate 9, so that the feeding is automated and the production efficiency of the enterprise is further improved.

[0027] The pushing mechanism includes a pushing platform 14 and a pushing cylinder 15. The pushing platform 14 has a groove that is adapted to the pallet 17. The lifting mechanism 13 includes a screw and a linear motor. The lower end of the screw is connected to the linear motor. The linear motor drives the screw to move up and down, so that the screw lifts the pallets 17 in the feeding mechanism 11 one by one from bottom to top.

[0028] The feeding bracket includes a feeding base and limiting rods 16. The limiting rods 16 are configured in several groups, and the groups of limiting rods 16 are vertically arranged on the side wall of the feeding base. The groups of limiting rods 16 form a limiting cavity, which is used to limit the support plate 17 on the feeding base. The lower end of the feeding base is provided with a feeding groove, and the lifting mechanism 13 lifts the support plate 17 on the feeding base through the feeding groove.

[0029] In the process of using this invention, the material preparation device 1 is first used to produce wet zeolite molecular sieve blanks, the first cutting device 2 is used to cut the wet zeolite molecular sieve blanks produced by the material preparation device 1, and the first conveying device 3 is used to convey the wet zeolite molecular sieve blanks cut by the first cutting device 2. At this time, the surface of the tilting plate 9 is flush with the surface of the pushing platform 14, and the lifting mechanism 13 lifts the pallet 17 in the feeding mechanism 11 through the groove onto the pushing platform 14. After the pushing cylinder 15 pushes the pallet 17 on the pushing platform 14 onto the surface of the tilting plate 9, the pushing cylinder 15 resets, and the tilting cylinder 10 drives the tilting plate 9 and the pallet 17 to rotate to the position of the first conveying device. 3. Vertical angle of conveying direction: When the wet zeolite molecular sieve on the first conveying device 3 touches the surface of the pallet 17, the second cutting mechanism 4 cuts the wet zeolite molecular sieve on the first conveying device 3 to form a single zeolite molecular sieve. After the second cutting mechanism 4 is completed, it is immediately reset. At this time, the flipping cylinder 10 drives the flipping plate 9 and the single zeolite molecular sieve on the flipping plate 9 to rotate clockwise by 90 degrees in sync. The pushing cylinder is used to push the single zeolite molecular sieve on the flipping plate 9 after it is flipped to the second conveying mechanism 6. After the pallet 17 on the flipping plate 9 is pushed, the pushing mechanism sequentially replenishes the pallet 17 on the feeding bracket to the flipping plate 9, and so on.

[0030] In this invention, pallets 17 are manually placed into the feeding mechanism 11, with a capacity of approximately 30 pallets per load. Three racks are used interchangeably, significantly reducing the frequency of manual operation. The feeding rack is conveyed to the area directly below the pushing platform 14 via the conveyor chain 12. The pallets 17 on the feeding mechanism 11 are then lifted onto the pushing platform 14 by the lifting mechanism 13, and then pushed onto the surface of the flipping plate by the pushing cylinder 15. After this process, the pallets 17 on the flipping plate 9 are pushed, and the cycle repeats until all pallets 17 are used or the program stops. The mechanism can reduce the frequency of manual plate loading, freeing up workers' workload and allowing them to take on other tasks, thus achieving the possibility of saving labor without affecting production capacity. It should be noted that the existing vertical molding process uses manual blank receiving and manual cutting. This method increases labor costs and reduces the company's production efficiency. In addition, manual cutting cannot achieve the effect of rapid cutting. After horizontal extrusion, it is necessary to cut through high-speed filament cutting and flip it into a vertical state to ensure that such honeycomb products do not close the cells after cutting, and that the products do not deform or sink.

[0031] Both the first cutting device 2 and the second cutting mechanism 4 include a cutting wire 18. The cutting wire 18 is used to cut the wet zeolite molecular sieve at an oblique angle. When the cutting wire 18 is running at high speed, the cut surface of the product is relatively flat, not prone to turning over, and without burrs. If the cutting wire 18 is cutting in a static state, the cut surface of the product is prone to turning over and closing the hole, and there will be many burrs on the cut surface. Products with the above conditions are all defective products. When the cutting wire 18 cuts the product at a certain angle to the product cutting surface, the force surface of the cutting wire 18 is very small when it just contacts the product surface. In this way, the cutting wire 18 is not easy to break, and the product is not easy to deform and block the hole. If the cutting wire 18 cuts parallel to the product cutting surface, the force surface of the product surface and the cutting wire 18 are both large, which easily produces broken wires, turning over, closing the hole, and many burrs on the product cutting surface.

[0032] This invention uses a flipping mechanism 5 to flip the horizontally conveyed wet blank to a vertically conveyed state, thereby avoiding the problem that the honeycomb hole end face will deform and sink when the wet blank is placed horizontally for a short time. On the one hand, it improves the appearance of the product, and on the other hand, it greatly improves the production efficiency of the product, reduces the defect rate of the product, and thus improves the production efficiency of the enterprise.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 the present invention should be included within the protection scope of the present invention.
