The outlets of the two particle adding assemblies can be communicated with the inlet of the collecting hopper. The two particle adding assemblies each comprise a particle weighing hopper and a particle discharging valve, and the particle discharging valve is used for controlling the on-off between the particle weighing hopper and the collecting hopper. The particle weighing module is arranged on the two particle weighing hoppers. Through the arrangement of the two particle adding assemblies, the particle weighing module can detect the weight of the material in the corresponding particle weighing hopper.

Description

Technical Field

[0001] This application relates to the field of baking grain processing technology, and in particular to a material addition mechanism for spraying and a baking grain spraying system. Background Technology

[0002] In the production process of pet baked goods, after the pelleted food is dried by drying equipment, oil, pulp, and palatability enhancers need to be added to the pellets to increase their energy and palatability. Spraying equipment manufacturers have always placed great emphasis on the research of spraying systems to achieve better spraying results and meet customer needs. However, in related technologies, materials are generally added using a single weighing hopper. This often fails to reach the minimum weight for spraying the last batch of material, resulting in unsprayed material and recycled material. Summary of the Invention

[0003] Therefore, it is necessary to provide a material adding mechanism and a baking grain spraying system that can effectively solve the problem of being unable to spray when the last batch of material does not reach the minimum weight for spraying, thus resulting in material being returned to the machine.

[0004] A material adding mechanism for spraying includes two particle adding components and a collecting hopper, the outlet of which is connected to a roller; the outlets of both particle adding components are connected to the inlet of the collecting hopper; each particle adding component includes a particle weighing hopper and a particle discharge valve, the particle discharge valve being used to control the connection between the particle weighing hopper and the collecting hopper; each particle weighing hopper is equipped with a particle weighing module, the particle weighing module being used to detect the weight of the material in the particle weighing hopper.

[0005] By setting up two particle adding components, when the material in one particle weighing hopper is discharged, the corresponding particle discharge valve is closed, and then material is added to the other particle weighing hopper. When the particle weighing module detects that the weight of the material in one particle weighing hopper reaches half of the set value, it stops adding material to that hopper and adds material to the other particle weighing hopper. When the particle weighing module detects that the weight of the material in the other particle weighing hopper reaches the set value, it stops adding material to that hopper and adds material to one of the hoppers. Then, the corresponding particle discharge valve is opened, allowing the material in the other particle weighing hopper to enter the drum through the collecting hopper. When the material in the other particle weighing hopper is discharged, the corresponding particle discharge valve is closed, and then material is added to the other particle weighing hopper. This process is repeated until the last batch of material is used. Using this method, the problem of not being able to spray when the last batch of material does not reach the minimum weight for spraying, thus generating recycled material, can be effectively solved. In addition, the parallel setting of the two particle adding components can reduce the height and facilitate space arrangement.

[0006] In one embodiment, the spraying material adding mechanism further includes a powder adding component, the collecting hopper includes two first inlets and a second inlet, the outlets of the two particle adding components are respectively connected to the two first inlets of the collecting hopper; the outlet of the powder adding component is connected to the second inlet of the collecting hopper.

[0007] In one embodiment, the powder adding component includes a powder weighing hopper and a powder discharge valve. The powder weighing hopper contains powder, and the powder discharge valve is used to control the connection and disconnection between the powder weighing hopper and the collecting hopper. A powder weighing module is provided on the powder weighing hopper, and the powder weighing module is used to detect the weight of the powder in the powder weighing hopper.

[0008] This application also provides a baking grain spraying system, including:

[0009] A spraying mechanism includes a drive assembly, a roller, an adding assembly, and a discharging assembly. The drive assembly drives the roller to rotate. Multiple loading plates and multiple unloading plates are arranged circumferentially inside the roller, with each loading plate and unloading plate corresponding to the other. Both loading and unloading plates are inclined relative to the central axis of the roller. The loading plates can lift materials, and the unloading plates can receive materials sliding off the loading plates. The roller has a discharge port that can receive materials sliding off the unloading plates. The adding assembly adds materials into the roller. The discharging assembly opens or closes the discharge port.

[0010] The spraying material adding mechanism is connected to the adding component and is used to convey the material into the roller;

[0011] A liquid adding mechanism, which is connected to the adding component, is used to spray liquid into the roller.

[0012] In the above scheme, by setting up a spraying mechanism, a spraying material adding mechanism, and a liquid adding mechanism, when the drive component drives the drum to rotate, the loading plate can lift the material at the bottom of the drum. Some of the material on the loading plate will fall back to the bottom of the drum due to its own gravity and the force of the spraying. When the material falls to the spraying position, it is sprayed with liquid, and some of the material will slide onto the discharge plate. The material falling onto the discharge plate will slide towards the discharge port. The loading plate and the discharge plate are inclined relative to the central axis of the drum, so that the material has a buffer when sliding down and is relatively gentle, which can effectively reduce the material breakage rate. At the same time, when the discharge port is in the closed state, the material slides down along the inner wall of the drum to the bottom of the drum, and can be lifted again by the loading plate as the drum rotates, which can effectively ensure that the material is sprayed evenly and ensure the quality of the finished product of the baked grain. When the discharge port is in the open state, the drum continues to rotate, and the material slides down from the discharge plate and slides out through the discharge port, which facilitates the collection of the baked grain.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] Please see Figure 1 and Figure 4This application relates to a material adding mechanism 200 for spraying, comprising two particle adding components 210 and a collecting hopper 230, the outlet of which is connected to a roller 120. The outlets of both particle adding components 210 are connected to the inlets of the collecting hopper 230. Particle material within the particle adding components 210 can be collected in the collecting hopper 230 and then conveyed to the roller 120.

[0039] Both particle adding components 210 include a particle weighing hopper 211 and a particle discharge valve 212. The particle weighing hopper 211 contains particles, and the particle discharge valve 212 controls the connection between the particle weighing hopper 211 and the collecting hopper 230. Specifically, the particle discharge valve 212 is located near the outlet of the particle weighing hopper 211. For example, the particle discharge valve 212 may be a solenoid valve.

[0040] A particle weighing module 213 is provided on the particle weighing hopper 211. The particle weighing module 213 is used to detect the weight of the particles in the particle weighing hopper 211. The particle weighing module 213 can be a weighing sensor.

[0041] For ease of understanding, the two particle weighing hoppers 211 can be referred to as the first weighing hopper and the second weighing hopper, respectively. The two particle weighing modules 213 can be referred to as the first weighing module and the second weighing module, respectively. The first weighing module is used to detect the weight of the particles in the first weighing hopper. The second weighing module is used to detect the weight of the particles in the second weighing hopper. The two particle discharge valves 212 can be referred to as the first discharge valve and the second discharge valve, respectively. The first discharge valve is located in the first weighing hopper, and the second discharge valve is located in the second weighing hopper.

[0042] When adding material, it is placed into the first weighing hopper. When the first weighing module detects that the weight of the material in the first weighing hopper reaches half of the set value, the addition of material to the first weighing hopper is stopped, and material is added to the second weighing hopper. When the second weighing module detects that the weight of the material in the second weighing hopper reaches half of the set value, the addition of material to the second weighing hopper is stopped, and material is added to the first weighing hopper. When the first weighing module detects that the weight of the material in the first weighing hopper reaches the set value, the addition of material to the first weighing hopper is stopped, and material is added to the second weighing hopper. Then, the first discharge valve is opened, allowing the material in the first weighing hopper to enter the drum 120 through the collecting hopper 230.

[0043] After the material in the first weighing hopper is discharged, the first discharge valve is closed, and then material is added back into the first weighing hopper. When the first weighing module detects that the weight of the material in the first weighing hopper reaches half of the set value, it stops adding material into the first weighing hopper and adds material into the second weighing hopper. When the second weighing module detects that the weight of the material in the second weighing hopper reaches the set value, it stops adding material into the second weighing hopper and adds material into the first weighing hopper. Then, the second discharge valve is opened, allowing the material in the second weighing hopper to enter the roller 120 through the collecting hopper 230. After the material in the second weighing hopper is discharged, the second discharge valve is closed, and then material is added back into the second weighing hopper. This process is repeated until the last batch of material is used. This method effectively solves the problem of the last batch of material not reaching the minimum weight for spraying, thus preventing the machine from receiving recycled material. Furthermore, the parallel connection of the two material adding components 210 reduces the height and facilitates space arrangement.

[0044] Please see Figure 1 and Figure 4 According to some embodiments of this application, optionally, the material adding mechanism 200 further includes a powder adding component 220, and the collecting hopper 230 includes two first inlets and a second inlet. The outlets of the two particle adding components 210 can be connected to the two first inlets of the collecting hopper 230, respectively. The outlet of the powder adding component 220 can be connected to the second inlet of the collecting hopper 230. The granular material in the particle adding component 210 and the powder in the powder adding component 220 can be collected in the collecting hopper 230 and then conveyed to the roller 120.

[0045] Please see Figure 1 and Figure 4 According to some embodiments of this application, optionally, the powder adding component 220 includes a powder weighing hopper 221 and a powder discharge valve 222. The powder weighing hopper 221 contains powder, and the powder discharge valve 222 is used to control the on / off connection between the powder weighing hopper 221 and the collecting hopper 230. Specifically, the powder discharge valve 222 is located near the outlet of the powder weighing hopper. Exemplarily, the powder discharge valve 222 may be a solenoid valve.

[0046] Please see Figure 1 and Figure 4 A powder weighing module 223 is installed on the powder weighing hopper 221. The powder weighing module 223 is used to detect the weight of the powder inside the powder weighing hopper 221. The powder is an attractant. The powder weighing module 223 can be a weighing sensor.

[0047] The powder weighing module 223 detects the weight of the powder in the powder weighing hopper 221. When powder needs to be added, it is placed into the powder weighing hopper 221. When the powder weighing module 223 detects that the weight of the powder in the powder weighing hopper 221 has reached the set value, it stops adding powder into the powder weighing hopper 221. Then, the powder discharge valve 222 is opened, allowing the powder to enter the collecting hopper 230.

[0048] Please see Figure 1 and Figure 2 This application also provides a baking grain spraying system 10, including a spraying mechanism 100, a material adding mechanism 200, and a liquid adding mechanism 300. The spraying mechanism 100 includes a drive assembly 110, a roller 120, an adding assembly 130, and a discharging assembly 140. The drive assembly 110 drives the roller 120 to rotate. The adding assembly 130 adds material into the roller 120. The roller 120 has a discharge port, and the discharging assembly 140 opens or closes the discharge port. The material adding mechanism 200 is connected to the adding assembly 130 and is used to convey material into the roller 120. The liquid adding mechanism 300 is connected to the adding assembly 130 and is used to spray liquid into the roller 120. The baking grain spraying system 10 also includes a support frame 400, on which the spraying mechanism 100 is mounted, and the support frame 400 supports the spraying mechanism 100.

[0049] It should be noted that when the liquid adding mechanism 300 and the spraying material adding mechanism 200 convey liquid and materials into the drum 120, the drive component 110 drives the drum 120 to rotate continuously to mix the liquid and materials evenly, which can ensure the quality of the finished product of the baked grain.

[0050] Please see Figure 1 , Figure 2 and Figure 3 The drum 120 has multiple feeding plates 121 and multiple dropping plates 122 arranged along its circumference. The feeding plates 121 and dropping plates 122 are arranged in a one-to-one correspondence, and both are inclined relative to the central axis of the drum 120. The feeding plates 121 can lift materials, and the dropping plates 122 can receive materials sliding off the feeding plates 121. The drum 120 has a discharge port that can receive materials sliding off the dropping plates 122. Specifically, the feeding plates 121 can lift materials located at the bottom of the drum 120.

[0051] More specifically, the roller 120 includes a cylindrical section and a conical section located near the discharge port. Multiple feeding plates 121 are evenly arranged circumferentially along the cylindrical section. Multiple discharge plates 122 are evenly arranged circumferentially along the conical section. The extending direction of the feeding plates 121 forms an angle with the central axis of the cylindrical section, and the extending direction of the discharge plates 122 also forms an angle with the central axis of the conical section. It should be understood that this application does not limit the inclination angle of the feeding plates 121 relative to the central axis of the cylindrical section, or the inclination angle of the discharge plates 122 relative to the central axis of the conical section; these angles can be set according to actual usage requirements. The goal is simply to ensure that the feeding plates 121 can lift the material, and the discharge plates 122 can receive the material sliding off the feeding plates 121.

[0052] As the loading plate 121 rotates upwards from the bottom of the cylindrical section, it lifts up the material at the bottom. Because there is an angle between the loading plate 121 and the central axis of the cylindrical section, when the roller 120 rotates to a certain position, some of the material on the loading plate 121 will fall back to the bottom of the cylindrical section due to its own gravity and the force of the spraying. When the material falls to the spraying position, it is sprayed with liquid, and some of the material will slide onto the discharge plate 122. The material falling onto the discharge plate 122 will slide towards the outlet. Since the outlet is closed, the material slides along the inner wall of the conical section to the bottom of the cylindrical section and can be lifted up again by the loading plate 121. As the roller 120 rotates continuously, the above process is repeated, effectively ensuring uniform material spraying. After spraying is completed, the outlet is opened, the roller 120 continues to rotate, and the material slides off the discharge plate 122 and out through the outlet. After the material in the roller 120 is discharged, the outlet is closed, waiting for the next material to enter.

[0053] By configuring the spraying mechanism 100, the spraying material adding mechanism 200, and the liquid adding mechanism 300, when the drive assembly 110 drives the roller 120 to rotate, the loading plate 121 can lift the material at the bottom of the roller 120. Some of the material on the loading plate 121 will fall back to the bottom of the roller 120 due to its own gravity and the force of the spraying. When the material falls to the spraying position, it is sprayed with liquid, and some of the material will slide onto the discharge plate 122. The material falling onto the discharge plate 122 will slide towards the discharge port. The loading plate 121 and the discharge plate 122... The roller 120 is tilted relative to its central axis, which cushions the material as it falls, making the fall smoother and effectively reducing the breakage rate. When the outlet is closed, the material slides down the inner wall of the roller 120 to the bottom of the roller 120, and can be picked up again by the loading plate 121 as the roller 120 rotates. This effectively ensures uniform spraying of the material and guarantees the quality of the finished product. When the outlet is open, the roller 120 continues to rotate, and the material slides down from the dropping plate 122 and out through the outlet, facilitating the collection of the baked grain.

[0054] The baking grain spraying system 10 of this application is described in detail below with reference to the accompanying drawings.

[0055] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the addition component 130 includes a first feed pipe 131, a second feed pipe 132, and a third feed pipe 133 communicating with the interior of the roller 120. One end of the second feed pipe 132 and the third feed pipe 133 extends into the interior of the roller 120, and a first nozzle 134 is provided on one end of the second feed pipe 132, and a second nozzle 135 is provided on one end of the third feed pipe 133.

[0056] Specifically, the spray material adding mechanism 200 is connected to the first feed pipe 131 and is used to convey material into the roller 120. The liquid adding mechanism 300 is connected to the second feed pipe 132 and the third feed pipe 133 and is used to spray liquid into the roller 120. More specifically, the first feed pipe 131 is connected to the outlet of the collecting hopper 230. The granular material in the granule adding component 210 and the powder in the powder adding component 220 can be collected in the collecting hopper 230 and then conveyed into the roller 120 through the first feed pipe 131.

[0057] It should be noted that the materials transported by the spray material addition mechanism 200 include particulate materials and attractants. The liquid added by the liquid addition mechanism 300 is oil-based, transported via the second feed pipe 132. The liquid added by the liquid addition mechanism 300 is slurry-based, transported via the third feed pipe 133.

[0058] More specifically, the first nozzle 134 is a conventional nozzle used to spray oil onto granular materials. The second nozzle 135 is an air atomizing nozzle, which sprays the poorly flowing slurry onto the granular materials, achieving a good atomization effect and ensuring the quality of the finished product.

[0059] Please see Figure 1 and Figure 5 According to some embodiments of this application, optionally, the liquid addition mechanism 300 includes an oil addition component 310 and a slurry addition component 320. The outlet of the oil addition component 310 can be connected to a second feed pipe 132 for supplying oil to the first nozzle 134. The outlet of the slurry addition component 320 can be connected to a third feed pipe 133 for supplying spray slurry to the second nozzle 135.

[0060] Please see Figure 1 and Figure 5The oil addition assembly 310 includes an oil inlet pipe 311 connected to the second feed pipe 132, an oil weighing hopper 312, an oil inlet valve 313, an oil buffer hopper 314, and an oil pump 315 sequentially arranged on the oil inlet pipe 311. The oil inlet valve 313 controls the connection and disconnection between the oil weighing hopper 312 and the oil buffer hopper 314. The oil buffer hopper 314 stores a set value of oil, and the oil pump 315 pumps the oil from the oil buffer hopper 314 into the second feed pipe 132. The oil addition assembly 310 also includes a first oil weighing module 316 and a second oil weighing module 317. The first oil weighing module 316 detects the weight of the oil in the oil weighing hopper 312. The second oil weighing module 317 detects the weight of the oil in the oil buffer hopper 314. Both the first oil weighing module 316 and the second oil weighing module 317 use load cells.

[0061] The oil addition assembly 310 also includes a first oil valve 3106 disposed on the oil inlet pipeline 311.

Oil can enter the oil weighing hopper 312 through the oil inlet pipe 311. Since the set oil inlet quantity is more than the actual oil consumption, when oil needs to be mixed, the oil inlet valve 313 needs to be opened, and then the oil is put into the oil buffer hopper 314 according to the differential weight method. When the required quantity is reached, the oil inlet valve 313 is closed. Specifically, a first stirring element 318 is provided in the oil buffer hopper 314 to stir the oil in the oil buffer hopper 314.

[0066] When oil needs to be sprayed, the first oil valve 3106 and the second oil valve 3107 are opened, and the oil pump 315 is started. When the second oil pressure detection module 3103 detects that the pressure in the oil inlet pipe 311 near the second feed pipe 132 is greater than the set value, the third oil valve 3108 is opened to spray the material. When the second oil pressure detection module 3103 detects that the pressure in the oil inlet pipe 311 near the second feed pipe 132 is lower than the oil stop setting value and the spraying time has been reached, the third oil valve 3108 is closed, and the oil pump 315 is turned off.

The third bypass is disposed between the first injection valve 319 and the second injection valve 3101, and is located near the second feed pipe 132. Specifically, a second pipe is also connected between the oil pump 315 and the oil buffer hopper 314. The first air release valve 3104 is disposed on the second pipe, and can be opened to vent air from the second pipe and the oil inlet pipe 311 to prevent air accumulation and thus ensure smooth delivery. The oil drain valve 3105 is disposed between the first injection valve 319 and the second oil pressure detection module 3103.

[0068] When the first oil pressure detection module 3102 detects that the pressure in the oil inlet pipe 311 near the oil pump 315 is greater than the set value, the pressure in the oil inlet pipe 311 is too high, and the first air vent valve 3104 needs to be opened to vent the oil inlet pipe 311. When it is necessary to clean the oil residue in the oil inlet pipe 311, ensure that the first fuel injection valve 319 and the drain valve 3105 are both closed, and close the third fuel valve 3108 and the second fuel valve 3107.

The second slurry weighing module 327 detects the weight of the slurry in the slurry buffer hopper 324. The slurry can enter the slurry weighing hopper 322 through the slurry inlet pipe 321. Since the slurry inlet setting is more than the actual slurry usage, when slurry needs to be prepared, the slurry inlet valve 323 needs to be opened, and then the slurry is put into the slurry buffer hopper 324 according to the differential weight method. When the required amount is reached, the slurry inlet valve 323 is closed. Specifically, a second agitator 328 is provided in the slurry buffer hopper 324 to agitate the slurry in the slurry buffer hopper 324.
