Description

Technical Field

[0001] This utility model relates to the field of mesh belt conveyor technology, specifically a mesh belt conveyor with an automatic cleaning device. Background Technology

[0002] Mesh belt conveyors, with their advantages of stable conveying, good air permeability, and strong load-bearing capacity, are widely used in material conveying processes across various industries. However, in actual use, dust, debris, and sticky impurities on the material surface easily adhere to the mesh openings and surface of the mesh belt. If not cleaned in time, this can lead to mesh blockage, affecting the conveyor's air permeability (especially in food drying conveying scenarios) and reducing material processing quality. Furthermore, residual impurities accumulate inside the equipment as the mesh belt circulates, increasing belt wear, shortening equipment lifespan, and potentially breeding bacteria (in the food and pharmaceutical industries), causing product quality and safety issues.

[0003] Based on the above, the inventors have discovered the following problems: The industry primarily uses manual or offline cleaning methods for cleaning mesh belt conveyors. Manual cleaning requires machine shutdown, which not only consumes significant labor costs but also interrupts the production process and reduces efficiency. Offline cleaning requires disassembling the mesh belt for washing, which is cumbersome and has a long cleaning cycle, failing to meet the needs of continuous production.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mesh belt conveyor with an automatic cleaning device in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a mesh belt conveyor with an automatic cleaning device, in order to solve the problem mentioned in the background art that the industry mostly uses manual or offline cleaning methods to clean mesh belt conveyors. Manual cleaning requires machine shutdown, which not only consumes a lot of labor costs but also interrupts the production process and reduces production efficiency; offline cleaning requires disassembling the mesh belt for cleaning, which is cumbersome and has a long cleaning cycle, and cannot meet the needs of continuous production.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A mesh belt conveyor with an automatic cleaning device includes a base frame, with support columns installed at the four corners of the top of the base frame. A conveyor frame is installed at the top of a pair of support columns. Conveyor rollers are rotatably connected to both ends of adjacent sides of the pair of conveyor frames. A conveyor mesh belt is fitted around the outer side of the pair of conveyor rollers. A cleaning mechanism for cleaning the conveyor mesh belt is provided at the bottom of the conveyor frame. A motor is installed on one side of one of the conveyor frames, and the output end of the motor is connected to one end of one of the conveyor rollers. A scraping mechanism is provided at the bottom of the conveyor mesh belt. The scraping mechanism includes a cleaning shovel, with rotating shafts installed at both ends of the cleaning shovel. A retaining seat is rotatably connected to one end of the rotating shaft. The top of the retaining seat is fixedly connected to the bottom of the conveyor frame. A torsion spring is fitted around the outer side of the rotating shaft, and one end of the torsion spring is fixedly connected to the inner side of the retaining seat. An impurity guide groove is installed at the top of the base frame.

[0007] Furthermore, the cleaning mechanism includes a pair of uprights, the top ends of the pair of uprights are fixedly connected to the bottom ends of the pair of conveyor frames, the inner side of the uprights is provided with lifting blocks, the inner side of the pair of lifting blocks is rotatably connected to the cleaning roller, and the top end of the cleaning roller is in contact with the bottom end of the conveyor belt.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by supporting the lifting block and the cleaning roller in the upright frame of the cleaning mechanism, the cleaning roller contacts the bottom end of the conveyor belt and cleans the surface material as the belt rotates, thereby realizing automatic cleaning during the conveying process, reducing manual cleaning costs, and improving conveying efficiency.

[0009] Furthermore, a spring is installed at the bottom end of the lifting block, and the bottom end of the spring is fixedly connected to the bottom end of the upright frame.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the spring at the bottom of the lifting block, the spring force pushes the lifting block and the sweeping roller to always be in contact with the conveyor belt upward. Even if there is slight wear or deformation of the conveyor belt, the contact pressure between the sweeping roller and the conveyor belt can be guaranteed, ensuring that the sweeping effect is not reduced.

[0011] Furthermore, sliding rods are slidably connected to both sides of the lifting block, and one side of the sliding rod is fixedly connected to the inner side of the upright.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the sliding rods connected to both sides of the lifting block guide the up and down movement of the lifting block, prevent the lifting block from shifting and causing the sweeping roller and conveyor belt to misalign, ensure the sweeping position is accurate, and improve the cleaning stability.

[0013] Furthermore, the surface of the cleaning roller is provided with a plurality of bristles, which are made of polyethylene.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the polyethylene bristles on the surface of the cleaning roller have moderate hardness and wear resistance, which can effectively clean material residues without scratching the surface of the conveyor belt, extending the service life of the conveyor belt, and preventing the bristles from falling off and contaminating the material.

[0015] Furthermore, the cleaning shovel is made of stainless steel, and its top end is in contact with the bottom end of the conveyor belt.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the cleaning shovel is made of stainless steel, which has corrosion resistance and high strength, and can be adapted to the conveying of wet or corrosive materials. It prevents the cleaning shovel from rusting and being damaged. The top of the cleaning shovel is attached to the mesh belt, which can efficiently scrape away stubborn materials in the gaps or on the surface of the mesh belt, thus improving the thoroughness of cleaning.

[0017] Furthermore, support bases are installed at the four corners of the bottom of the bottom frame, and the bottom of the support bases is provided with anti-slip texture.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by increasing the contact area with the ground through the support base at the bottom of the base frame, and increasing the friction with the ground through the anti-slip texture at the bottom of the support base, the conveyor is prevented from sliding due to vibration or material weight during operation, thus ensuring the overall stability of the equipment and avoiding displacement of the conveying position.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This mesh belt conveyor with an automatic cleaning device has a stable equipment foundation built through a base frame and support columns. The conveyor frame supports the conveyor rollers and the conveyor mesh belt, realizing continuous material conveying. The cleaning mechanism cleans residual materials on the surface of the conveyor mesh belt. The cleaning shovel in the shovel mechanism is always in contact with the conveyor mesh belt under the action of the rotating shaft and torsion spring, scraping off stubborn attached materials and keeping the conveyor mesh belt clean. The torsion spring can adapt to slight fluctuations in the mesh belt, ensuring a continuous and stable shoveling effect and avoiding material residue from affecting subsequent conveying. The flow guide trough collects and guides impurities after cleaning. The lifting block and cleaning roller are supported by a vertical frame in the cleaning mechanism. The cleaning roller contacts the bottom of the conveyor belt and cleans the surface material as the belt rotates, achieving automatic cleaning during the conveying process, reducing manual cleaning costs and improving conveying efficiency. A spring at the bottom of the lifting block pushes the lifting block and cleaning roller to always maintain upward contact with the conveyor belt. Even with slight wear or deformation of the belt, the contact pressure between the cleaning roller and the belt is guaranteed, ensuring that the cleaning effect is not diminished. The lifting block is slidably connected to both sides... The sliding rod guides the up-and-down movement of the lifting block, preventing it from shifting and causing misalignment between the cleaning roller and the conveyor belt. This ensures precise cleaning position and improves cleaning stability. The polyethylene bristles on the cleaning roller surface are moderately hard and wear-resistant, effectively cleaning material residue without scratching the conveyor belt surface, extending its lifespan and preventing bristle shedding that could contaminate materials. The stainless steel cleaning shovel, with its corrosion resistance and high strength, is suitable for conveying damp or corrosive materials, preventing rust and damage. The shovel tip fits snugly against the belt, efficiently scraping away stubborn materials from gaps or surfaces, enhancing cleaning thoroughness. The support base at the bottom of the frame increases the contact area with the ground, and the anti-slip texture at the bottom increases friction, preventing slippage due to vibration or material weight during operation, ensuring overall equipment stability and preventing conveyor position deviation. This invention effectively scrapes away stubborn materials and cleans residual materials from the conveyor belt surface, keeping it clean and possessing high practical value.
