Description

Technical Field

[0001] This utility model relates to the field of plate feeder technology, and in particular to a plate quantitative feeder with cleaning function. Background Technology

[0002] Plate-type quantitative feeders are ideal equipment for continuous weighing and feeding of bulk materials. They are used in building materials, mining, metallurgy and other fields, and can adapt to various production environments. They can continuously and quantitatively convey various block materials. For example, the prior art (authorization announcement number CN222117868U) discloses a reversible plate-type quantitative feeder. Through the interlacing of the first chain plate and the second chain plate, combined with the setting of dustproof rail and rubber roller, the conveyor belt can ensure good stability when it is driven in both forward and reverse directions, avoiding the possibility of belt deviation and loosening between chain plates. The setting of pressure roller and tension adjustment component allows the device to not only complete the accurate weighing and tensioning of materials, but also to center the conveyor belt, effectively ensuring the centering effect during feeding.

[0003] However, due to the continuous conveying of materials, after prolonged use, materials may adhere to the surface of the plate conveyor belt. If not treated in time, as the amount of deposits gradually increases, it will directly affect the uniform conveying of materials, and thus affect the feeding accuracy of the plate feeder. However, in the existing technology, cleaning usually requires stopping the machine for cleaning, which is inefficient. Therefore, this utility model proposes a plate quantitative feeder with cleaning function to solve the problems existing in the prior art. Utility Model Content

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figures 1-4 As shown, this embodiment proposes a plate-type quantitative feeder with cleaning function, including a frame 1, on which a plate-type conveyor belt 2 is installed. In this device, two sets of symmetrically arranged drive rollers are installed on the frame 1, and each drive roller is driven by an independent motor. The two sets of drive rollers are located on both sides of the plate-type conveyor belt 2, and the rotation of the drive rollers drives the movement of the plate-type conveyor belt 2 to ensure smooth material conveying. Specifically, the motors of the two sets of drive rollers are coordinated by an external synchronous control system to ensure that the drive rollers on both sides rotate synchronously and to avoid the plate-type conveyor belt 2 from deviating or moving unevenly.

[0022] Support columns 3 are installed at the lower end of the frame 1, and several sets of support columns 3 are evenly arranged. In this embodiment, four sets of support columns 3 are evenly distributed on the left and right sides below the frame 1. An assembly frame 4 is installed on the inner side of the frame 1. The cross-section of the assembly frame 4 is U-shaped. A drive shaft 5 is installed on the inner side of the assembly frame 4 through bearings. Two sets of drive shafts 5 are arranged horizontally and symmetrically. The drive shafts 5 are driven by a first motor 6. The first motor 6 is located on the outer side of the assembly frame 4 and is fixedly connected to the assembly frame 4 through a bracket. Cams 7 are installed on the drive shafts 5, and several sets of cams 7 are arranged. In this embodiment, five sets of cams 7 are installed on each set of drive shafts 5, and their states are different. During operation, the first motor 6 drives the drive shafts 5 to rotate, thereby driving the cams 7 to continuously impact the plate conveyor belt 2, generating periodic impact force. The impact force generated by the impact knocks off the material attached to the plate conveyor belt 2, ensuring the cleanliness of the conveyor belt surface. Furthermore, a PLC controller is installed on the assembly frame 4, which is electrically connected to the first motor 6.

[0023] Specifically, the cam 7 includes a body 10, and a rubber impact head 11 is provided on the outer side of the body 10. The rubber impact head 11 is connected to the body 10 through a spring telescopic member 12, and several sets of spring telescopic members 12 are evenly arranged. In this embodiment, each cam 7 has three sets of spring telescopic members 12. Specifically, the rubber impact head 11 is responsible for contacting the plate conveyor belt 2 and generating impact force to remove the material attached to the surface of the conveyor belt. The rubber material has good elasticity and impact resistance, which can effectively transmit the impact force while protecting the surface of the conveyor belt from damage. During this process, when the rubber impact head 11 contacts the surface of the plate conveyor belt 2, the spring telescopic member 12 absorbs part of the impact energy and causes the rubber impact head 11 to rebound, forming a periodic impact force. This makes the impact process gentler and avoids excessive impact force from damaging the plate conveyor belt 2. Thus, by combining the design of the rubber impact head 11 and the spring telescopic member 12, an efficient and gentle cleaning effect can be provided.

[0024] A base plate 8 is provided below the frame 1, and the base plate 8 is connected to the support column 3. A collection box 9 is installed on the base plate 8, and a groove 22 is provided on the base plate 8, which is adapted to the collection box 9. In this embodiment, the cross-section of the groove 22 is U-shaped, which facilitates the installation and disassembly of the collection box 9. When installing the collection box 9, it is only necessary to place it on the base plate 8, align it with the inlet of the groove 22, and push it in all the way. Furthermore, materials that fall due to impact enter the collection box 9.

[0025] A cleaning assembly is installed on the collection box 9. The cleaning assembly includes two sets of symmetrically arranged cleaning rollers 13. The shafts of the cleaning rollers 13 are connected to the collection box 9 through bearings and driven by a second motor. One set of cleaning rollers 13 has a soft brush installed on its outer side, and the other set of cleaning rollers 13 has a hard brush installed on its outer side. In this embodiment, the two sets of cleaning rollers 13 are located on both sides below the assembly frame 4. During the cleaning process, the cleaning rollers 13 with hard brushes are used first for cleaning, followed by impact, and finally the cleaning rollers 13 with soft brushes are used for cleaning. Correspondingly, the rotation direction of the cleaning rollers 13 is towards the center of the collection box 9. Specifically, the hard brushes are used to clean harder or more adhesive materials first, such as large particles or substances adhering to the conveyor belt. The design of the hard brushes can deeply remove material residues and help break through more stubborn attachments. The soft brushes are responsible for cleaning finer materials or cleaning loose materials that have been impacted. Thus, through a reasonable workflow, this device can improve material cleaning efficiency and ensure that the materials in the collection box 9 can be collected quickly and effectively.

[0026] Dust collection components are installed on both sides below the frame 1, and the input end of the dust collection components is connected to the collection box 9. The dust collection components include a mounting plate 14, which is fixedly connected to the support column 3. A fan 15 is installed on the mounting plate 14. Dust collection hoods 16 are installed at both the front and rear ends of the collection box 9. The dust collection hoods 16 are connected to the input end of the fan 15 through a filter cartridge 17. Furthermore, the collection box 9 is provided with an inlet, and two sets of inlets are symmetrically arranged. Limiting ports 18 are provided on both sides of the inlet, and the upper end of the limiting ports 18 is connected to the outside. Both ends of the dust collection hoods 16 extend into the limiting ports 18. The cooperation between the limiting ports 18 and the inlets facilitates the installation and removal of the dust collection hoods 16. During operation, the dust hood 16 is connected to the input end of the filter cartridge 17 through a pipe, and the output end of the filter cartridge 17 is connected to the input end of the fan 15 through a pipe. Accordingly, during the cleaning process, the fan 15, the filter cartridge 17 and the dust hood 16 work together to suppress the spread of dust, ensuring the health of the operators and the safety of the production environment.

[0027] Baffles 19 are installed on both the front and rear sides of the frame 1. Limiting wheels 20 are installed on the baffles 19, and several sets of limiting wheels 20 are evenly arranged. The several sets of limiting wheels 20 are located on the inner and outer sides of the plate conveyor belt 2. Through the cooperation of the baffles 19 and the limiting wheels 20, the plate conveyor belt 2 can be limited.

[0028] Guide rollers 21 are installed on both sides below the frame 1. The shaft of the guide roller 21 is connected to the support column 3 at the corresponding position through bearings. The guide roller 21 is located inside the plate conveyor belt 2. The function of the guide roller 21 is to guide the plate conveyor belt 2 through the cleaning area of ​​this device.
