Description

Technical Field

[0001] This invention belongs to the field of other special equipment manufacturing technology, specifically a conveying device for wheat flour production. Background Technology

[0002] Flour is made from wheat, and its main processing steps are as follows: After cleaning to remove impurities and adjusting the moisture content of the wheat grains, the endosperm is separated from the germ and bran using specialized equipment. The endosperm is then ground into flour. Flour production encompasses four main stages: initial cleaning, finishing, milling, and blending / packaging. In the packaging stage, the flour is first bagged in the bagging area and then transported by conveyor belt to the sewing area for sealing.

[0003] A patent with publication number CN217417217U discloses a cleaning device for wheat flour packaging, including a conveyor belt body. The device is characterized in that a support frame is provided on one side of the conveyor belt body, and a fixed frame is hinged to one end of the support frame. A cleaning brush is rotatably connected to the fixed frame. The cleaning brush can be separated from the conveyor belt body under the push of the conveyed materials and automatically reset after the materials pass through. The support frame and the fixed frame are provided with a driving device for driving the cleaning brush to rotate. The cleaning brush can suck up the dust and impurities remaining on the conveyor belt body.

[0004] The above solution still has some problems in practical application. When using the cleaning brush to suck up and clean the flour attached to the conveyor belt, due to long-term use, the flour keeps falling and accumulating. The flour at the bottom of the pits on the surface of the conveyor belt will be compacted by the bagged flour, which means that the cleaning brush can only suck up the loose flour on the surface during the cleaning process, while the compacted flour is more difficult to clean. In addition, during the process of the cleaning brush removing flour, some flour will stick to the bristles of the cleaning brush, which will reduce the subsequent cleaning efficiency of the cleaning brush.

[0005] Therefore, the present invention provides a conveying device for wheat flour production. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides a conveying device for wheat flour production, including a machine body, a fixed motor fixedly connected to one end of the machine body, and a conveyor belt drivingly connected to the output end of the fixed motor;

[0008] An auxiliary component is provided on the upper surface of the machine body. The auxiliary component includes a fixed frame fixed to the upper part of the machine body. A brush roller is slidably arranged on the fixed frame. An auxiliary frame is arranged above the brush roller. The lower surface of the auxiliary frame is provided with bristles to assist in cleaning the brush roller.

[0009] The fixed frame has a fixed groove, and the fixed groove is also equipped with a spraying assembly. The spraying assembly includes a second rack plate that is slidably disposed inside the fixed groove. A positioning frame is fixedly connected to the bottom end of the second rack plate. Several connecting pipes are fixedly connected to the lower surface of the positioning frame, and a spray plate is fixedly connected to the lower surface of each connecting pipe.

[0010] Preferably, the auxiliary component further includes a rotating gear rotatably connected to the inner wall of the fixed frame, the transmission gear meshing with a first rack plate, a connecting frame fixedly connected to one side of the first rack plate, sliders fixedly connected to both ends of the connecting frame, a brush roller rotatably connected between the two sliders, and a built-in motor disposed inside one of the sliders.

[0011] Preferably, a limiting guide rail is fixedly connected to the inner wall of the fixed frame, a limiting guide groove is formed in the limiting guide rail, a limiting block is slidably connected in the limiting guide groove, and the limiting block is fixedly connected to the first rack plate and the auxiliary frame.

[0012] Preferably, the fixed frame is provided with a limiting component for each slider position. The limiting component includes an auxiliary plate fixed to both sides of the inner wall of the fixed frame, and the auxiliary plate is disposed on both sides of the slider.

[0013] Preferably, the rotating gear also meshes with the second rack plate, and a limiting block is fixedly connected to one side of the second rack plate, and the limiting block slides along the limiting guide groove opened on one side of the limiting guide rail.

[0014] Preferably, after the conveyor belt has finished conveying the flour, the drive gear rotates, which in turn drives the first rack plate meshing with the gear to move downward until the brush roller comes into contact with the conveyor belt. At this time, the built-in motor inside one of the sliders drives the brush roller to rotate, cleaning the flour in the pits on the surface of the conveyor belt. Auxiliary frame fixed to one side of the first rack plate has several rows of bristles fixed to its lower surface, and the bristles clean each other with the rotating brush roller.

[0015] Preferably, the spraying assembly further includes a rotating shaft fixed to the inner wall of the fixed frame, a rotating roller fixed to the circumferential surface of the rotating shaft, a protruding plate fixed to the circumferential surface of the rotating roller, a positioning groove provided in the positioning frame, a plurality of springs fixed to the positioning groove, one end of the plurality of springs fixed to the same conical plate, a plurality of fixing holes provided on the surface of the conical plate, and a plurality of connecting cavities provided inside the positioning frame, the connecting cavities communicating with the connecting pipe.

[0016] Preferably, after the brush roller has finished cleaning the flour on the surface of the conveyor belt, the drive gear rotates in the opposite direction to lift the brush roller. At this time, the second rack plate meshing on the other side of the gear moves down until the spray plate on the lower surface of the positioning frame approaches the conveyor belt and sprays warm water on the pits on the surface of the conveyor belt.

[0017] Preferably, during the spraying process, the rotating shaft that drives the fixed inner wall rotates, the rotating shaft drives the rotating roller to rotate, and the rotation of the rotating roller drives the convex plate to rotate. During the rotation of the convex plate, it continuously collides with the conical plate in the positioning frame. The convex plate will squeeze the conical plate into the positioning groove, the conical plate will squeeze the spring, and then the fixing hole on the surface of the conical plate will align with the connecting cavity. At this time, the warm water stored inside the positioning frame is squeezed and sprayed into the spray plate. After being dispersed by the spray plate, it is sprayed out in the form of mist to soften the flour in the pit.

[0018] Preferably, the limiting guide rail is provided in two sets, one set corresponding to the first rack plate for limiting, and the other set corresponding to the second rack plate for limiting.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The conveying device for wheat flour production of the present invention, after the flour is conveyed by the conveyor belt, drives the rotating gear to rotate, thereby driving the first rack plate meshing with the rotating gear to move downward until the brush roller abuts against the conveyor belt. At this time, the built-in motor inside one of the sliders drives the brush roller to rotate, cleaning the flour in the pits on the surface of the conveyor belt. Auxiliary frame fixed to one side of the first rack plate, with several rows of bristles fixed to the lower surface of the auxiliary frame, cleans the flour with the rotating brush roller.

[0021] Multi-stage cleaning can more thoroughly remove flour adhering to the conveyor belt surface, improving cleaning quality; brush bristles assist in cleaning the brush rollers, extending their service life and maintaining stable cleaning results; the spray plate position is adjustable and can be switched with the brush rollers; the entire process is highly automated, requiring minimal manual intervention for cleaning, effectively improving work efficiency and reducing labor costs.

[0022] 2. The conveying device for wheat flour production described in this invention includes an auxiliary component in which a rotating gear is rotatably connected to the inner wall of a fixed frame. When the rotating gear is driven to rotate, it drives the first rack plate meshing with it to move. The connecting frame fixed to one side of the first rack plate moves accordingly, and the sliders at both ends of the connecting frame also move, thereby driving the brush roller rotatably connected between the two sliders to move. The built-in motor inside one of the sliders is activated, which drives the brush roller to rotate. In this way, the brush roller can change its position by moving and clean the surface of the conveyor belt by rotating. At the same time, the cooperation between the rotating gear and the first rack plate enables precise control of the brush roller position.

[0023] 3. The conveying device for wheat flour production described in this invention lifts the brush roller by rotating the gear in the opposite direction, while the second rack plate moves down to bring the spray plate closer to the conveyor belt, achieving precise switching between cleaning and spraying processes. The rotating shaft, rotating roller, convex plate, and conical plate work together to spray warm water in a mist form through mechanical collision and extrusion, which can evenly and deeply soften the flour in the grooves of the conveyor belt. Compared with ordinary spraying methods, the cleaning is more thorough, effectively avoiding flour residue, ensuring smooth subsequent operation of the conveyor belt, and extending the service life of the equipment.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1: As Figures 1 to 6As shown in the embodiment of the present invention, a conveying device for wheat flour production includes a body 1. A fixed motor 11 is fixedly connected to one end of the body 1, and a conveyor belt 12 is drivenly connected to the output end of the fixed motor 11. An auxiliary component is provided on the upper surface of the body 1. The auxiliary component includes a fixed frame 2 fixedly connected to the upper part of the body 1. A brush roller 27 is slidably arranged on the fixed frame 2. An auxiliary frame 29 is arranged above the brush roller 27. The lower surface of the auxiliary frame 29 is provided with bristles to assist in cleaning the brush roller 27. A fixed groove 21 is opened in the fixed frame 2. A spraying component is also provided inside the fixed groove 21. The spraying component includes a second rack plate 211 slidably arranged inside the fixed groove 21. A positioning frame 212 is fixedly connected to the bottom end of the second rack plate 211. A plurality of connecting pipes 218 are fixedly connected to the lower surface of the positioning frame 212. A spray plate 216 is fixedly connected to the lower surface of each connecting pipe 218.

[0035] Specifically, when using the aforementioned cleaning brush to suck up and clean the flour attached to the conveyor belt 12, due to prolonged use, the flour continuously falls and accumulates. The flour at the bottom of the pits on the surface of the conveyor belt 12 is compacted by the bagged flour, causing the cleaning brush to only be able to suck up the loose flour on the surface during the cleaning process. The compacted flour is more difficult to clean. In addition, during the process of removing flour with the cleaning brush, some flour will adhere to the bristles of the cleaning brush, which will reduce the subsequent cleaning efficiency of the cleaning brush.

[0036] Therefore, the present invention solves the above problems by setting the above structure. First, after the conveyor belt 12 has finished conveying the flour, the drive gear 22 is rotated, which in turn drives the first rack plate 23 meshing with the gear 22 to move downward until the brush roller 27 comes into contact with the conveyor belt 12. At this time, the built-in motor inside one of the sliders 25 drives the brush roller 27 to rotate, cleaning the flour in the pits on the surface of the conveyor belt 12. The auxiliary frame 29 fixed to one side of the first rack plate 23 has several rows of bristles fixed to its lower surface. The bristles clean each other with the rotating brush roller 27.

[0037] Multi-stage cleaning can more thoroughly remove flour adhering to the surface of the conveyor belt 12, improving cleaning quality; the brush roller 27 is cleaned with bristles to extend its service life and maintain a stable cleaning effect; the position of the spray plate 216 is adjustable and can be switched with the brush roller 27; the whole process is highly automated, requiring little manual intervention for cleaning, effectively improving work efficiency and reducing labor costs.

[0038] like Figure 2As shown, the auxiliary components in this embodiment also include a rotating gear 22 rotatably connected to the inner wall of the fixed frame 2, a transmission gear meshing with a first rack plate 23, a connecting frame 28 fixedly connected to one side of the first rack plate 23, and sliders 25 fixedly connected to both ends of the connecting frame 28. A brush roller 27 is rotatably connected between the two sliders 25, and a built-in motor is provided inside one of the sliders 25.

[0039] Specifically, in the auxiliary components, the rotating gear 22 is rotatably connected to the inner wall of the fixed frame 2. When the rotating gear 22 is driven to rotate, it will drive the first rack plate 23 meshing with it to move. The connecting frame 28 fixed to one side of the first rack plate 23 moves accordingly, and the sliders 25 at both ends of the connecting frame 28 also move, thereby driving the brush roller 27 rotatably connected between the two sliders 25 to move. The built-in motor inside one of the sliders 25 is activated, which can drive the brush roller 27 to rotate. In this way, the brush roller 27 can change its position by moving and clean the surface of the conveyor belt 12 by rotating. At the same time, the cooperation between the rotating gear 22 and the first rack plate 23 realizes the precise control of the position of the brush roller 27.

[0040] By allowing the cleaning range and position of the brush roller 27 to be flexibly adjusted, it can better adapt to items of different sizes and shapes, improving the comprehensiveness and targeting of cleaning. The built-in motor drives the brush roller 27 to rotate, enhancing the cleaning power and effect, effectively removing stubborn stains from the surface of items, and improving the overall cleaning quality.

[0041] like Figure 3 As shown, in this embodiment, the inner wall of the fixed frame 2 is fixedly connected to a limiting guide rail 210, and a limiting guide groove 215 is opened in the limiting guide rail 210. A limiting block 24 is slidably connected in the limiting guide groove 215. The limiting block 24 is fixedly connected to the first rack plate 23 and the auxiliary frame 29. The fixed frame 2 is provided with a limiting component corresponding to the position of each slider 25. The limiting component includes an auxiliary plate 26 fixed to both sides of the inner wall of the fixed frame 2. The auxiliary plate 26 is arranged on both sides of the slider 25.

[0042] Specifically, a limiting guide groove 215 is provided in the limiting guide rail 210 fixed to the inner wall of the fixed frame 2. The limiting block 24 slides in the limiting guide groove 215 and is fixed to the first rack plate 23 and the auxiliary frame 29. This allows the first rack plate 23 and the auxiliary frame 29 to slide stably along the trajectory of the limiting guide groove 215 when moving, avoiding deviation. At the same time, the fixed frame 2 is provided with limiting components for each slider 25. The auxiliary plates 26 on both sides of the inner wall are located on both sides of the slider 25. When the slider 25 moves, the auxiliary plates 26 restrict it from both sides to prevent the slider 25 from shaking or deviating during the movement, ensuring that the slider 25 can only move in the predetermined direction. This ensures that the brush roller 27 connected to the slider 25 can move stably and accurately, achieving effective cleaning of items.

[0043] The cooperation between the limiting guide rail 210 and the limiting block 24 ensures the stability of the movement of the first rack plate 23 and the auxiliary frame 29. The limitation of the slider 25 by the limiting component ensures the accuracy of the movement of the brush roller 27, improves the stability and reliability of the equipment operation, and enables the cleaning work to be carried out efficiently and accurately, thereby improving the cleaning quality.

[0044] like Figure 3 As shown, in this embodiment, the rotating gear 22 also meshes with the second rack plate 211. A limiting block 24 is fixedly connected to one side of the second rack plate 211, and the limiting block 24 slides along the limiting guide groove 215 opened on one side of the limiting guide rail 210.

[0045] Specifically, the rotating gear 22 meshes with the first rack plate 23 and the second rack plate 211 simultaneously. When the rotating gear 22 rotates, it will not only drive the first rack plate 23 to move, but also cause the second rack plate 211 to move accordingly. The limiting block 24 fixed to one side of the second rack plate 211 slides along the limiting guide groove 215 opened on one side of the limiting guide rail 210 to ensure that the second rack plate 211 remains stable during the movement and will not deviate, thereby driving the spraying assembly and other components to move along a predetermined trajectory.

[0046] The linkage control of multiple components is realized, which improves the coordination of equipment operation. The cooperation between the limit block 24 and the limit guide groove 215 ensures the stability of the movement of the second rack plate 211, so that the spraying components can accurately reach the designated position, effectively improving the stability of equipment operation and the accuracy of cleaning work.

[0047] Example 2: Figures 1 to 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the spraying assembly further includes a rotating shaft 213 fixed to the inner wall of the fixed frame 2, a rotating roller 214 fixed to the circumferential surface of the rotating shaft 213, a protruding plate 217 fixed to the circumferential surface of the rotating roller 214, a positioning groove 220 is provided in the positioning frame 212, a plurality of springs 221 are fixed in the positioning groove 220, one end of the plurality of springs 221 is fixed to the same conical plate 222, a plurality of fixing holes 223 are provided on the surface of the conical plate 222, and a plurality of connecting cavities 219 are provided inside the positioning frame 212, the connecting cavities 219 are connected to the connecting pipe 218.

[0048] Specifically, after the brush roller 27 finishes cleaning the flour from the surface of the conveyor belt 12, it drives the rotating gear 22 to rotate in the opposite direction, thereby lifting the brush roller 27. At this time, the second rack plate 211, which is engaged on the other side of the rotating gear 22, moves down until the spray plate 216 on the lower surface of the positioning frame 212 approaches the conveyor belt 12, spraying warm water onto the pits on the surface of the conveyor belt 12. During the spraying process, the rotating shaft 213 fixed to the inner wall is driven to rotate, and the rotating shaft 213 drives the rotating roller 214 to rotate. The rotating drive plate 217 rotates. During the rotation, the plate 217 continuously collides with the cone plate 222 inside the positioning frame 212. The plate 217 will squeeze the cone plate 222 into the positioning groove 220. The cone plate 222 squeezes the spring 221. Then the fixing hole 223 on the surface of the cone plate 222 aligns with the connecting cavity 219. At this time, the warm water stored inside the positioning frame 212 is squeezed and sprayed into the spray plate 216. After being dispersed by the spray plate 216, it is sprayed out in a mist form to soften the flour in the pit.

[0049] While the reverse rotating gear 22 lifts the brush roller 27, the second rack plate 211 moves down to bring the spray plate 216 closer to the conveyor belt 12, achieving precise switching between cleaning and spraying processes. The rotating shaft 213, rotating roller 214, convex plate 217, and conical plate 222 work together to spray warm water in a mist form through mechanical collision and squeezing. This can evenly and deeply soften the flour in the pits of the conveyor belt 12. Compared with ordinary spraying methods, the cleaning is more thorough, effectively avoiding flour residue, ensuring smooth subsequent operation of the conveyor belt 12, and extending the service life of the equipment.

[0050] like Figure 3 As shown, in this embodiment, the limiting guide rail 210 is provided with two sets, one set corresponding to the first rack plate 23 for limiting, and the other set corresponding to the second rack plate 211 for limiting.

[0051] Specifically, two sets of limiting guide rails 210 are respectively set for the first rack plate 23 and the second rack plate 211. When the rotating gear 22 drives the first rack plate 23 to move, the corresponding set of limiting guide rails 210 guides and restricts the first rack plate 23 through its internal limiting structure, so that it moves along a predetermined trajectory. Similarly, when the rotating gear 22 drives the second rack plate 211 to move, the other set of limiting guide rails 210 limits the second rack plate 211 to ensure its stable and accurate movement, ensure that all components work together, avoid mutual interference between the first rack plate 23 and the second rack plate 211 during movement, improve the stability and accuracy of equipment operation, and limit the two sets of limiting guide rails 210 respectively, so that components such as the brush roller 27 and the spray assembly can reach the designated position independently and accurately, effectively improving the quality and efficiency of cleaning work and enhancing the reliability and durability of the equipment.

[0052] Working principle: First, after the conveyor belt 12 has finished conveying the flour, it drives the rotating gear 22 to rotate, which in turn drives the first rack plate 23, which meshes with the rotating gear 22, to move downward until the brush roller 27 comes into contact with the conveyor belt 12. At this time, the built-in motor inside one of the sliders 25 drives the brush roller 27 to rotate, cleaning the flour in the pits on the surface of the conveyor belt 12. The auxiliary frame 29, which is fixed to one side of the first rack plate 23, has several rows of bristles fixed to its lower surface. The bristles clean each other with the rotating brush roller 27.

[0053] Multi-stage cleaning can more thoroughly remove flour adhering to the surface of conveyor belt 12, improving cleaning quality; brush bristles assist in cleaning brush roller 27, extending the service life of brush roller 27 and maintaining stable cleaning effect; the position of spray plate 216 is adjustable and can be switched with brush roller 27; the whole process is highly automated, requiring little manual intervention for cleaning, effectively improving work efficiency and reducing labor costs.

[0054] Specifically, in the auxiliary components, the rotating gear 22 is rotatably connected to the inner wall of the fixed frame 2. When the rotating gear 22 is driven to rotate, it will drive the first rack plate 23 that meshes with it to move. The connecting frame 28 fixed to one side of the first rack plate 23 moves accordingly, and the sliders 25 at both ends of the connecting frame 28 also move, thereby driving the brush roller 27 rotatably connected between the two sliders 25 to move. The built-in motor inside one of the sliders 25 is activated, which can drive the brush roller 27 to rotate. In this way, the brush roller 27 can change its position by moving and clean the surface of the conveyor belt 12 by rotating. At the same time, the cooperation between the rotating gear 22 and the first rack plate 23 realizes the precise control of the position of the brush roller 27.

[0055] By making the cleaning range and position of the brush roller 27 flexibly adjustable, it can better adapt to items of different sizes and shapes, improve the comprehensiveness and targeting of cleaning. The built-in motor drives the brush roller 27 to rotate, which enhances the cleaning power and effect, effectively removes stubborn stains from the surface of items, and improves the overall cleaning quality.

[0056] Additionally, a limiting guide groove 215 is provided on the limiting guide rail 210 fixed to the inner wall of the fixed frame 2. The limiting block 24 slides in the limiting guide groove 215 and is fixed to the first rack plate 23 and the auxiliary frame 29. This allows the first rack plate 23 and the auxiliary frame 29 to slide stably along the trajectory of the limiting guide groove 215 when moving, avoiding deviation. At the same time, the fixed frame 2 is provided with limiting components corresponding to each slider 25 position. The auxiliary plates 26 on both sides of the inner wall are located on both sides of the slider 25. When the slider 25 moves, the auxiliary plates 26 restrict it from both sides to prevent the slider 25 from shaking or deviating during the movement, ensuring that the slider 25 can only move in the predetermined direction. This ensures that the brush roller 27 connected to the slider 25 can move stably and accurately, achieving effective cleaning of items.

[0057] The cooperation between the limiting guide rail 210 and the limiting block 24 ensures the stability of the movement of the first rack plate 23 and the auxiliary frame 29, while the limitation of the slider 25 by the limiting component ensures the accuracy of the movement of the brush roller 27, improves the stability and reliability of the equipment operation, and enables the cleaning work to be carried out efficiently and accurately, thereby improving the cleaning quality.

[0058] After the brush roller 27 finishes cleaning the flour from the surface of the conveyor belt 12, it drives the rotating gear 22 to rotate in the opposite direction, thereby lifting the brush roller 27. At this time, the second rack plate 211 meshing on the other side of the rotating gear 22 moves down until the spray plate 216 on the lower surface of the positioning frame 212 approaches the conveyor belt 12, spraying warm water onto the pits on the surface of the conveyor belt 12. During the spraying process, the rotating shaft 213 fixed to the inner wall is driven to rotate, and the rotating shaft 213 drives the rotating roller 214 to rotate. The convex plate 217 is driven to rotate. During the rotation, the convex plate 217 continuously collides with the conical plate 222 inside the positioning frame 212. The convex plate 217 will squeeze the conical plate 222 into the positioning groove 220. The conical plate 222 squeezes the spring 221. Then the fixing hole 223 on the surface of the conical plate 222 aligns with the connecting cavity 219. At this time, the warm water stored inside the positioning frame 212 is squeezed and sprayed into the spray plate 216. After being dispersed by the spray plate 216, it is sprayed out in a mist form to soften the flour in the pit.

[0059] While the reverse rotating gear 22 lifts the brush roller 27, the second rack plate 211 moves down to bring the spray plate 216 closer to the conveyor belt 12, achieving precise switching between cleaning and spraying processes. The rotating shaft 213, rotating roller 214, convex plate 217, and conical plate 222 work together to spray warm water in a mist form through mechanical collision and squeezing. This can evenly and deeply soften the flour in the pits of the conveyor belt 12. Compared with ordinary spraying methods, the cleaning is more thorough, effectively avoiding flour residue, ensuring smooth subsequent operation of the conveyor belt 12, and extending the service life of the equipment.
