[0031] The side plate is fixedly installed with guide rod 25 on the side away from bottom plate 24, and sliding block 26 is slidingly installed on guide rod 25, the bottom surface of sliding block 26 is attached to bottom plate 24, and support panel 27 is connected between the two groups of sliding blocks 26, and the support panel 27 is adapted to slide along the linear direction of guide rod 25 through sliding block 26, and the cleaning part is installed on the support panel 27, and the cleaning part includes support plate 216 fixedly installed on the support panel 27 close to both ends, and the two groups of support plates 216 are detachably installed with brush 217, and in the running state of conveying mesh belt 1, the brush 217 is not in contact with mesh belt body 12.

[0032] Driving parts are arranged between the two groups of side plates, the driving parts include support pieces 211 fixedly installed on the side of the two groups of side plates close to each other, one end of the two groups of support pieces 211 is coaxial, a screw column 29 is bearing-mounted between one end of the two groups of support pieces 211, a helical groove 210 is formed on the screw column 29 in the axial direction of the screw column 29, one group of the support pieces 211 is fixedly installed with an auxiliary rod 212, the auxiliary rod 212 is penetrated by a linkage rod 214, a connecting rod 28 is fixedly installed on the side of the support panel 27 close to the screw column 29, one end of the linkage rod 214 is connected with the connecting rod 28, and a guide groove 215 is formed on the auxiliary rod 212 to limit the moving direction of the linkage rod 214;

[0033] One end of the linkage rod 214 is in a spherical structure, and the spherical structure is in the helical groove 210 in the default state, the screw column 29 is suitable for being driven to rotate by a driving piece, the bottom surface of the placing plate 22 is fixedly installed with a pneumatic cylinder 23, the telescopic end of the pneumatic cylinder 23 penetrates the placing plate 22 and is connected with the bottom surface of the bottom plate 24, and the pneumatic cylinder 23 is suitable for driving the brush 217 to be close to or away from the mesh belt body 12;

[0034] In the material conveying stage, the mesh belt body 12 of the conveying mesh belt 1 is circulated under the driving of power, and the support 11 and the support column 13 ensure the stability of the whole conveying structure. At this time, the brush 217 of the cleaning and brushing assembly 2 is controlled to be in the low position by the pneumatic cylinder 23, and is kept in the non-contact state with the mesh belt body 12, so as to avoid interfering with the material conveying process.

[0035] When the mesh belt needs to be cleaned, the cleaning stage is entered. First, the pneumatic cylinder 23 is started, the telescopic end of the pneumatic cylinder 23 pushes the bottom plate 24 to rise along the inner groove of the placing plate 22, and drives the brush 217 to be close to the mesh belt body 12 until the brush 217 contacts the mesh belt body 12. Then, the driving assembly 3 drives the screw column 29 to rotate, the helical groove 210 on the screw column 29 cooperates with the spherical end of the linkage rod 214, the guide groove 215 of the auxiliary rod 212 limits the moving direction of the linkage rod 214, and the rotating movement of the screw column 29 is converted into the linear reciprocating movement of the linkage rod 214. The linkage rod 214 drives the support panel 27 through the connecting rod 28, the sliding block 26 slides on the guide rod 25, and then the brush 217 is driven to reciprocate along the width direction of the mesh belt, so that the brush 217 can reciprocally brush and clean the surface of the mesh belt body 12, and then remove the particles in the mesh holes or the surface sticky material;

[0036] In the present application, when the brush 217 reciprocates along the width direction of the mesh belt, so that the brush 217 can brush the surface of the mesh belt body 12 back and forth, the surface of the mesh belt body 12 can be sprayed with cleaning agent by manual operation to improve the cleaning effect of the mesh belt body 12. After cleaning is completed, the pneumatic cylinder 23 is retracted, the brush 217 is lowered and reset, the screw column 29 stops rotating, and returns to the initial state.

[0037] The adjustable contact cleaning of the brush 217 is realized by the air cylinder 23. The non-contact design in the non-working state reduces the wear and energy consumption of the brush 217, and the cooperation of the spiral groove 210 and the guide groove 215 ensures that the brush 217 can cover the entire width of the mesh belt, effectively solving the problems of easy blocking and difficult cleaning of the traditional mesh belt. In addition, the detachable brush 217 is convenient to replace and maintain, and can adapt to the cleaning needs of different materials. The cleaning and brushing assembly 2 can also be flexibly adjusted in position or replaced, thereby improving the overall efficiency and reliability of the dryer.

[0038] Referring to Figures 3 to 5 Specifically, the brush 217 has a hollow shaft (not marked in the figure), and a connecting head 218 is threadedly connected to one end of the shaft. The connecting head 218 is adapted to be connected to an external water supply device through a hose. In addition, inclined atomizing nozzles are arranged on the brush 217 near both ends, which are adapted to spray water on the surface of the mesh belt body 12.

[0039] When the mesh belt body 12 needs to be cleaned, the external water supply device delivers cleaning liquid or water to the connecting head 218 through the hose. The connecting head 218 is threadedly connected to the hollow shaft of the brush 217, so that the cleaning liquid enters the inside of the shaft. The inclined atomizing nozzles at both ends of the brush 217 are in communication with the inside of the shaft. The cleaning liquid is sprayed from the atomizing nozzles under the action of pressure, forming a fan-shaped or conical water mist that covers the surface of the mesh belt body 12. Since the atomizing nozzles are installed obliquely, the direction of water spraying forms an angle with the running direction of the mesh belt, which can effectively wash off the sticky materials and particulate impurities on the surface of the mesh belt.

[0040] Under the action of the driving part of the cleaning and brushing assembly 2, the brush 217 reciprocates along the width direction of the mesh belt, so that the water spraying area of the atomizing nozzles covers the entire width of the mesh belt, achieving comprehensive cleaning. After cleaning, the water supply device stops supplying water, and the remaining water can be dried by hot air in the drying area or by air drying, thereby improving the cleaning effect, especially for the removal of sticky materials.

[0041] Referring to Figures 3 to 5 Specifically, the two guide plates 219 are fixedly installed on the two sides of the two groups of support plates 216. The guide plates 219 are obliquely arranged and can shield the cleaning and brushing assembly 2, so as to avoid the materials falling off after being cleaned by the brush 217 from adhering to the cleaning and brushing assembly 2. In addition, the guide plates 219 are adapted to move synchronously with the brush 217, thereby always playing a role of assisting in receiving the materials falling off after being cleaned.

[0042] During the cleaning process of the dryer mesh belt, the guide plate 219 cooperates with the brush 217 to improve the cleaning effect. When the cleaning brush assembly 2 is started, the driving part drives the brush 217 to reciprocate along the width direction of the mesh belt, at this time, the guide plate 219 fixedly installed on both sides of the two groups of support plates 216 moves synchronously with the brush 217. Due to the inclined arrangement of the guide plate 219, on the one hand, it can form a physical barrier to intercept the granular or viscous materials falling during the cleaning of the mesh belt body 12 by the brush 217, avoiding the materials from splashing directly to other parts (such as guide rod 25, spiral column 29, etc.) of the cleaning brush assembly 2, reducing the interference and wear of impurities to the internal structure of the assembly;

[0043] On the other hand, the inclined surface of the guide plate 219 allows the falling materials to slide down along the inclined surface of the guide plate 219 under the action of gravity, playing a role in auxiliary material collection and flow guiding. No matter where the brush 217 moves to the mesh belt, the guide plate 219 always maintains the state of shielding and material collection, ensuring the self-cleaning of the cleaning brush assembly 2, reducing the maintenance frequency, and at the same time, ensuring efficient collection of materials and preventing the accumulation of residual materials from affecting the running efficiency of the dryer.

[0044] Referring to Figures 3 to 5 Specifically, the roller shaft of the brush 217 is connected to the support plate 216 by a bolt, which provides a stable installation basis for the brush 217. When the brush 217 is worn out after long-term use or needs to be replaced with a different type of brush 217 to adapt to different material cleaning needs, the operator only needs to unscrew the bolt to quickly remove the brush 217 from the support plate 216, install a new brush 217, significantly reducing the maintenance difficulty, improving the maintainability and flexibility of the equipment, and ensuring the continuous and efficient operation of the dryer mesh belt cleaning function.

[0045] Referring to Figures 3 to 4 Specifically, a collection box 220 is arranged between the two sides of the distance between the placement plate 22 and the support frame 21, and the top end of the collection box 220 has a protruding part which can be lapped on the placement plate 22 and the support frame 21;

[0046] During the cleaning process of the dryer mesh belt, the collection box 220 cooperates with the cleaning brush assembly 2 to collect the cleaning waste. The protruding part at the top end of the collection box 220 can be lapped on the placement plate 22 and the support frame 21, respectively, and stably erected in the gap between them, forming an open material receiving space;

[0047] When the brush 217 reciprocates under the action of the driving part to clean the mesh belt body 12, the guide plate 219 intercepts and guides the granular or viscous materials falling during the cleaning, so that they slide down along the inclined surface of the guide plate 219. At this time, the collection box 220 is located just below the guide plate 219, receiving the falling waste, avoiding the materials from scattering in other areas inside the dryer, causing secondary pollution or equipment blockage;

[0048] In addition, the lap joint installation design of the collection box 220 is convenient to disassemble. When the waste in the box accumulates to a certain amount, the operator can easily take it down for cleaning, and after emptying, it can be re-lap jointed back to the original position to continue to play the role of waste collection, ensuring the clean environment inside the dryer and maintaining the continuous and efficient operation of the cleaning brush assembly 2.

[0049] Referring to Figures 4 to 5 Specifically, the driving assembly 3 includes an angle piece 31 fixedly installed on the placement plate 22, and a motor 32 fixedly installed on the side surface of the angle piece 31. The output end of the motor 32 is connected with one end of the screw column 29 through a connecting shaft, and the connecting shaft penetrates a set of support pieces 211.

[0050] The driving assembly 3 is drivingly connected with the screw column 29 through the motor 32, and provides power for the cleaning brush assembly 2. The motor 32 is stably installed on the placement plate 22 through the angle piece 31, ensuring the stability during operation. When the dryer mesh belt needs to be cleaned, the motor 32 is powered on and started, and the connecting shaft at the output end drives the screw column 29 to rotate synchronously. The connecting shaft penetrates a set of support pieces 211, and realizes flexible rotation under the cooperation of bearings, reducing friction loss. When the screw column 29 rotates, the helical groove 210 on the surface thereof interacts with the spherical end of the linkage rod 214, and the guide groove 215 on the auxiliary rod 212 constrains the movement direction of the linkage rod 214, converting the rotary motion of the screw column 29 into the linear reciprocating motion of the linkage rod 214. The linkage rod 214 drives the support panel 27 through the connecting rod 28, so that the sliding block 26 slides on the guide rod 25, and then drives the brush 217 to reciprocate along the width direction of the mesh belt, completing the cleaning work on the surface of the mesh belt body 12.

[0051] In summary: during the material conveying stage, the mesh belt body 12 stably operates under the support of the support 11 and the support column 13. At this time, the brush 217 of the cleaning brush assembly 2 is controlled by the cylinder 23 to be in a low position, and is in a non-contact state with the mesh belt, avoiding interference with the material conveying. When cleaning is needed, the cylinder 23 pushes the brush 217 to rise to contact with the mesh belt, and at the same time, the motor 32 of the driving assembly 3 drives the screw column 29 to rotate, and through the cooperation of the helical groove 210 and the linkage rod 214, the rotary motion is converted into the reciprocating linear motion of the brush 217 along the width direction of the mesh belt, realizing the overall brushing and cleaning of the surface and mesh holes of the mesh belt.

[0052] In the process, the hollow roller inside the brush 217 is connected with the atomizing nozzle which can be externally supplied with water, and sprays fan-shaped or conical water mist to wash the viscous material and particulate impurities by water flow impact force; the guide plate 219 is arranged obliquely and moves synchronously with the brush 217, which can not only shield the splashing material and protect the internal structure of the cleaning brush assembly 2, but also guide the waste material to the collecting box 220 below through the inclined surface to avoid secondary pollution or equipment blockage caused by material scattering. After cleaning, the air cylinder 23 drives the brush 217 to reset and return to the initial state.

[0053] By cleaning and brushing, the particles stuck in the mesh and the viscous material adsorbed on the surface are effectively removed, the mesh belt air permeability is restored, the hot air and the material are fully contacted, and the drying uniformity and product quality stability are improved; the combination of atomizing water spraying and mechanical brushing significantly enhances the cleaning efficiency and reduces the problem of reduced drying efficiency caused by material residues; the detachable brush 217 and the overlapping collecting box 220 are convenient for maintenance and cleaning.

[0054] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any equivalent embodiments with equivalent changes are equivalent to the above embodiments. Any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are still within the scope of the present application.
