Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a conveying mesh belt cleaning device. Background Art

[0002] The single-layer mesh belt dryer, as a widely used continuous drying equipment, plays an important role in many industries such as pharmaceuticals, food, and chemicals. The core concept of its design is that it can efficiently process sheet, strip, granular, and some paste-like materials with good air permeability. Through continuous operation, the materials can achieve the ideal drying effect while maintaining their original shape.

[0003] Especially in the production process of traditional Chinese medicine decoction pieces, the role of this dryer is even more significant. Driven by the motor, the conveying mesh belt of the dryer moves smoothly, and the materials are evenly laid on the surface of the mesh belt. As the mesh belt moves, the materials are gradually dried under the action of hot air. However, although the single-layer mesh belt dryer has many technical advantages, some problems have also emerged in the actual production process.

[0004] One of the obvious problems is that the materials are easily adhered to the conveying mesh belt. This adhesion phenomenon not only affects the drying effect of the materials but also may reduce the working efficiency of the equipment. More seriously, due to the adhesion of the materials to the mesh belt, manual cleaning is required regularly. Such cleaning work is both time-consuming and laborious, especially when dealing with some materials with strong viscosity. Sometimes, in order to clean the adhered materials, it is even necessary to stop the machine for in-depth cleaning, which will undoubtedly greatly reduce the production efficiency.

[0017] As a further improvement of the above technical solution, the cleaning blades are made of rubber material.

[0018] As a further improvement of the above technical solution, a plurality of support legs are provided at the lower end of the collection box.

[0019] Compared with the related art, the beneficial effects of the present utility model are:

[0020] The present utility model aims to provide an efficient and automated conveyor belt cleaning device, which is particularly suitable for the continuous drying process of traditional Chinese medicine decoction pieces in a dryer. In the production process of traditional Chinese medicine decoction pieces, the dryer is an essential part, and the conveyor belt, as an important component of the dryer, undertakes the key task of continuously conveying products.

[0021] As the drying process continues, material residues are likely to appear on the conveyor belt. To ensure the drying effect of traditional Chinese medicine decoction pieces and the cleanliness of the conveyor belt, the cleaning device provided by the present utility model plays a crucial role.

[0022] During the operation of the dryer, the conveyor belt rotates continuously to achieve the continuous conveyance of traditional Chinese medicine decoction pieces. At the same time, the driving member in the cleaning device drives the cleaning roller to rotate. The cleaning blades installed on the cleaning roller rotate with the rotation of the cleaning roller, and the parts of these blades in contact with the conveyor belt effectively clean it. In this way, the material residues attached to the conveyor belt are cleaned and scraped off, ensuring the cleanliness of the belt.

[0023] Most of the materials scraped off by cleaning directly fall into the collection device below the cleaning roller, facilitating subsequent cleaning and processing. However, some material residues may adhere to the cleaning blades. To solve this problem, the present utility model also specially designs a scraper assembly. When the cleaning roller drives the cleaning blades to rotate and pass by the scraper assembly, the scraper assembly can quickly and effectively scrape off the material residues attached to the cleaning blades. These scraped-off material residues also fall into the collection device, achieving the comprehensive collection of materials.

[0024] The entire cleaning process does not require manual participation and does not require the dryer to stop. This means that during the operation of the dryer, the conveyor belt can be cleaned and maintained in real time. This not only greatly improves the production efficiency of the product but also ensures the cleanliness and drying effect of the conveyor belt. In addition, through continuous cleaning, the mesh holes of the conveyor belt can maintain permeability, thus ensuring the drying effect of traditional Chinese medicine decoction pieces. At the same time, the setting of the scraper assembly also ensures the use effect of the cleaning blades and extends their service life.

[0036] Embodiment 1

[0037] Combined with Figure 1 、 Figure 2 As shown, the present embodiment provides a conveying mesh belt cleaning device for cleaning the conveying mesh belt 120 of a dryer, including a cleaning roller 210, a collecting device 300, and a scraper assembly 400.

[0038] The cleaning roller 210 is installed on the body 110 of the dryer. The cleaning roller 210 is located below the conveying mesh belt 120. A plurality of cleaning blades 220 are evenly distributed on the side wall of the cleaning roller 210. The cleaning blades 220 press against the end face of the conveying mesh belt 120 close to the cleaning roller 210. The cleaning roller 210 can rotate under the driving action of a driving member; the collecting device 300 is arranged below the cleaning roller 210 for collecting the falling material residues; the scraper assembly 400 is arranged in the collecting device 300 for scraping the material residues attached to the cleaning blades 220.

[0039] The conveying mesh belt cleaning device provided in this embodiment is an indispensable part in the production process of traditional Chinese medicine decoction pieces. The drying machine is an essential link, and the conveying mesh belt 120, as an important component of the drying machine, undertakes the key task of continuously conveying products. As the drying process continues, material residues are likely to appear on the conveying mesh belt 120. To ensure the drying effect of traditional Chinese medicine decoction pieces and the cleanliness of the conveying mesh belt 120, the cleaning device provided by the present utility model plays a crucial role. During the operation of the drying machine, the conveying mesh belt 120 rotates continuously to achieve the continuous conveyance of traditional Chinese medicine decoction piece products. At the same time, the driving member in the cleaning device drives the cleaning roller 210 to rotate. The cleaning blades 220 installed on the cleaning roller 210 rotate along with the rotation of the cleaning roller 210, and the parts of these blades in contact with the conveying mesh belt 120 effectively clean it. In this way, the material residues attached to the conveying mesh belt 120 are cleaned and scraped off, ensuring the cleanliness of the mesh belt. Most of the materials cleaned and scraped off will directly fall into the collection device 300 below the cleaning roller 210, facilitating subsequent cleaning and processing. However, a part of the material residues may adhere to the cleaning blades 220. To solve this problem, the present utility model also specially designs a scraper assembly 400. When the cleaning roller 210 drives the cleaning blades 220 to rotate and pass by the scraper assembly 400, the scraper assembly 400 can quickly and effectively scrape off the material residues attached to the cleaning blades 220. These scraped-off material residues also fall into the collection device 300, achieving the comprehensive collection of materials.

[0040] The entire cleaning process does not require manual participation and does not require the drying machine to be shut down. This means that during the operation of the drying machine, the conveying mesh belt 120 can be cleaned and maintained in real time. This not only greatly improves the production efficiency of the product but also ensures the cleanliness of the conveying mesh belt 120 and the drying effect. In addition, through continuous cleaning, the mesh holes of the conveying mesh belt 120 can maintain permeability, thus ensuring the drying effect of traditional Chinese medicine decoction piece products. At the same time, the setting of the scraper assembly 400 also ensures the use effect of the cleaning blades 220 and extends their service life.

[0041] In some embodiments, the rotation direction of the cleaning roller 210 is opposite to the traveling direction of the conveying mesh belt 120 near the end face of the cleaning roller 210; by setting the rotation direction of the cleaning roller 210 opposite to the traveling direction of the conveying mesh belt 120 near the end face of the cleaning roller 210, it is ensured that when the cleaning roller 210 rotates at a low speed, there is still a relatively high relative speed between the cleaning blades 220 and the conveying mesh belt 120, ensuring the cleaning and conveying ability of the cleaning blades 220 for the conveying mesh belt 120; of course, in other embodiments of the present invention, the rotation direction of the cleaning roller 210 may also be the same as the traveling direction of the conveying mesh belt 120 near the end face of the cleaning roller 210, as long as the rotation speed of the cleaning roller 210 is different from the traveling speed of the conveying mesh belt 120 near the end face of the cleaning roller 210.

[0042] In some embodiments, a bearing seat 130 is provided on the body 110 of the dryer, and there are two bearing seats 130 which are symmetrically arranged on both sides of the conveying mesh belt 120. A transmission shaft 140 is provided between the two bearing seats 130, the cleaning roller 210 is sleeved on the transmission shaft 140, and the driving member is arranged on one of the bearing seats 130 and is in transmission connection with the transmission shaft 140; by providing two bearing seats 130 and arranging the two bearing seats 130 on both sides of the conveying mesh belt 120, while being able to provide stable and reliable rotational support for the transmission shaft 140, it is ensured that it will not interfere with the full cleaning of the conveying mesh belt 120 by the cleaning roller 210 driving the cleaning blades 220, and the layout is more reasonable.

[0043] In some embodiments, the collecting device 300 includes a collecting box 310, and the upper opening area of the collecting box 310 is larger than the cleaning area of the cleaning roller 210, so that the material residues scraped by the cleaning blades 220 on the conveying mesh belt 120 can all fall into the collecting box 310, avoiding environmental pollution; the scraping plate assembly 400 is arranged in the collecting box 310, so that when the scraping plate assembly 400 scrapes and removes the materials attached to the cleaning blades 220, the materials can directly fall into the collecting box 310, further reducing environmental pollution.

[0044] In some embodiments, the bottom of the collecting box 310 is inclined, and a discharge port 320 is opened at the lower end of the bottom of the collecting box 310, which is convenient for collecting the materials collected by the collecting box 310 and discharging them from the discharge port 320, facilitating regular cleaning by workers.

[0045] In some embodiments, the cleaning roller 210 is located inside the collection box 310, and the transmission shaft 140 penetrates through the side wall of the collection box 310. By disposing the cleaning roller 210 inside the collection box 310, most of the structure of the cleaning blade 220 is located inside the collection box 310, further reducing the probability that the residual material scraped off splashes out of the collection box 310 and improving the collection effect of the collection box 310 on the material.

[0046] In some embodiments, the scraper assembly 400 includes a scraper 410. Connecting seats 420 are provided at both ends of the scraper 410, and the connecting seats 420 are fixedly connected to the inner wall of the collection box 310. The rotation of the cleaning roller 210 can drive the cleaning blade 220 to sweep across the scraper 410. During the rotation of the cleaning blade 220 along with the cleaning roller 210, the scraper 410 can be attached to the working surface of the cleaning blade 220 and clean and scrape it, avoiding the accumulation of residual material on the cleaning blade 220 and ensuring the cleaning effect of the cleaning blade 220 on the conveyor belt 120.

[0047] In some embodiments, the distance between the scraper 410 and the axis of the cleaning roller 210 is less than or equal to the distance between the end face of the conveyor belt 120 close to the cleaning roller 210 and the axis of the cleaning roller 210, so that the cleaning and scraping area of the scraper 410 on the cleaning blade 220 is larger than the cleaning working area of the cleaning blade 220 on the conveyor belt 120, ensuring the thorough cleaning and scraping of the cleaning blade 220 by the scraper 410.

[0048] In some embodiments, the conveyor belt 120 of the dryer has a loading end and an unloading end 150. The cleaning roller 210 is disposed below the conveyor belt 120 close to the unloading end 150, so that the conveyor belt 120 is immediately cleaned and scraped by the cleaning blade 220 when it transfers downward after transporting the material, avoiding the residual material in the gap of the conveyor belt 120 from directly falling on the ground during the traveling process and reducing environmental pollution.

[0049] In some embodiments, the cleaning blade 220 is made of rubber material. Rubber has good elasticity and wear resistance, which enables the cleaning blade 220 to maintain a stable cleaning effect when dealing with various complex proportioned materials, and at the same time extends the service life. In addition, the rubber material also has certain corrosion resistance, enabling the cleaning blade 220 to maintain stable performance in harsh environments and providing a reliable guarantee for the cleaning work.

[0050] In some embodiments, a plurality of support legs are provided at the lower end of the collection box 310. When the collection box 310 is placed on either flat or slightly uneven ground, these support legs can effectively support the entire collection box 310, preventing it from shaking or tilting, thereby ensuring the stability and safety of the collection box 310. At the same time, these support legs also have a certain anti-slip function, enabling the collection box 310 to be stably placed even on wet or smooth surfaces.

[0051] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
