Description

Technical Field

[0001] This application relates to the field of product cleaning technology, specifically to a cleaning device. Background Technology

[0002] In actual production and processing, it is usually necessary to clean the processed products, such as removing adhesives and oils, and then drying them. Currently, cleaning machines are commonly used for product cleaning. The cleaning process is roughly as follows: the processed product is manually removed from the processing equipment and placed in a special fixture, which is then placed into the cleaning machine for cleaning. After the cleaning machine cleans and dries the product, the fixture and the cleaned product are removed from the machine, and the fixture is then transferred to a designated location. However, this product cleaning process requires frequent manual disassembly and reassembly of the product, as well as loading and unloading, resulting in low cleaning efficiency and high cleaning costs. Utility Model Content

[0003] In view of the above, it is necessary to propose a cleaning device to achieve online cleaning of products, improve cleaning efficiency, and reduce cleaning costs.

When the drying conveyor transfers products to the air-cutting conveyor, the air-cutting conveyor receives and transfers the products. When the air-cutting conveyor transfers products to the drying chamber, the drying chamber dries the products to remove excess liquid, while a cooling fan blows air onto the products to dissipate heat. The temperature of the drying chamber is lower than the temperature of the hot air generated by the drying fan. When the drying conveyor transfers products to the discharge conveyor, the discharge conveyor receives and transports the products to the designated location.

[0022] The cleaning equipment of this application embodiment, through the coordinated operation of a feeding device, a spraying device, a drying device, an air-cutting device, and a discharging device, can directly interface with external processing equipment to achieve product cleaning and drying. This enables online product cleaning, eliminating the need for frequent product disassembly and reassembly, as well as loading and unloading, thereby improving cleaning efficiency, reducing manual labor, and lowering labor costs. Furthermore, since product disassembly is eliminated, the number of specialized fixtures and related tools can be reduced, thus lowering material costs. Attached Figure Description

The number of drying fans 32 may be three, and the drying fans 32 may be high-pressure fans with a power of 5KW, 5.5KW, etc. Understandably, the drying frame 34 can be integrally formed with the spray frame 26 or they can be formed separately, and the drying conveying mechanism 31 and the spray conveying mechanism 21 can be integrally formed or they can be formed separately.

[0036] The air-cutting device 40 includes an air-cutting conveying mechanism 41, a drying chamber 42, and a cooling fan 43. One end of the air-cutting conveying mechanism 41 is connected to the other end of the drying conveying mechanism 31 to receive the product.

[0039] In this embodiment, the cleaning equipment 100 connects the feeding conveying mechanism 11 of the feeding device 10 to the external processing equipment when cleaning products. The products processed by the external processing equipment enter the feeding conveying mechanism 11 of the feeding device 10 in two rows and are then conveyed to the spray conveying mechanism 21. The spray conveying mechanism 21 then conveys the products sequentially to the first spraying mechanism 22, the first air blowing mechanism 23, the second spraying mechanism 24, and the second air blowing mechanism 25.

[0040] When the spray conveyor 21 conveys the product to the first spray mechanism 22, the first spray mechanism 22 sprays a first liquid onto the product. The first liquid, such as a medicinal solution, can be used to remove impurities such as glue and oil from the softened product. When the spray conveyor 21 conveys the product to the first air blowing mechanism 23, the first air blowing mechanism 23 blows air onto the product to remove the first liquid and the glue, oil, and other impurities that have been removed by the first liquid.

[0041] When the spray conveyor 21 conveys the product to the drying conveyor 31, the drying conveyor 31 receives and conveys the product. While the drying conveyor 31 conveys the product, the drying fan 32 generates hot air and blows it onto the product through the drying air knife assembly 33 to dry the product. When the drying conveyor 31 conveys the product to the air-cutting conveyor 41, the air-cutting conveyor 41 receives and conveys the product. When the air-cutting conveyor 41 conveys the product to the drying chamber 42, the drying chamber 42 dries the product to remove excess liquid, while the cooling fan 43 blows air onto the product to dissipate heat. The temperature of the drying chamber 42 is lower than the temperature of the hot air generated by the drying fan 32. When the drying conveyor 31 conveys the product to the discharge conveyor 51, the discharge conveyor 51 receives and conveys the product to a designated location, thereby achieving online cleaning of the product.

[0042] Please see Figure 2In this embodiment, the first spraying mechanism 22 includes a first spray chamber 221, a first liquid storage tank 222, a first spray pump 223, a first filter 224, and a plurality of first nozzles 225. The first spray chamber 221 is disposed on the spraying transmission mechanism 21, that is, the spraying transmission mechanism 21 transports the product through the first spray chamber 221. The first liquid storage tank 222 is disposed on the spraying frame 26, and is located below the spraying transmission mechanism 21 and communicates with the first spray chamber 221, that is, the first liquid in the first spray chamber 221 can flow back to the first liquid storage tank 222. The first spray pump 223 is disposed on the first liquid storage tank 222. The first filter 224 communicates with the first spray pump 223. The plurality of first nozzles 225 are disposed in the first spray chamber 221 and are all communicated with the first filter 224. The plurality of first nozzles 225 are all disposed above the spraying transmission mechanism 21 for spraying the first liquid onto the product. The first spray chamber 221 and the first liquid storage tank 222 can both be made of stainless steel plate. The power of the first spray pump 223 is, for example, 1.1KW and the pumping pressure is adjustable. The pumping pressure of the first spray pump 223 can be from 0.1Mpa to 0.6Mpa. The first spray pump 223 is equipped with an anti-backflow device (not shown) to prevent the first liquid from flowing back. The first filter 224 can filter impurities such as dust and aluminum shavings in the first liquid. The filtration accuracy of the first filter 224 can be 20μ. The first nozzle 225 can be fan-shaped. The orifice diameter of the first nozzle 245 is, for example, 1.1mm. There can be multiple first nozzles 225. For example, multiple first nozzles 225 can be divided into upper and lower layers. The upper layer has six sections, with four first nozzles 225 in each section, for a total of twenty-four first nozzles 225 in the upper layer. The first nozzles 225 in the upper layer can move closer to or further away from the spray transmission mechanism 21. The moving stroke of the first nozzles 225 in the upper layer is, for example, 50mm to 100mm. The lower layer has two sections, with four first nozzles 225 in each section, for a total of eight first nozzles 225 in the lower layer.

[0043] Thus, by configuring the first spray chamber 221, the first liquid storage tank 222, the first spray pump 223, the first filter 224, and multiple first nozzles 225, the first spray mechanism 22 achieves the effect of spraying the product with a first liquid. Furthermore, the first liquid can circulate between the first spray chamber 221 and the first liquid storage tank 222, improving the utilization rate of the first liquid and reducing the product cleaning cost. In addition, by configuring the first filter 224, the first liquid is filtered, preventing it from clogging the first nozzles 225 and ensuring that the first nozzles 225 can smoothly spray the first liquid.

[0044] In this embodiment, to ensure the smooth return of the first liquid in the first spray chamber 221 to the first storage tank 222, the first spray mechanism 22 further includes a first filtration pump 226, a first filter 227, and a first pressure gauge 228.

Thus, by setting the first filtration pump 226 and the first filter 227, the first liquid in the first spray chamber 221 is smoothly returned to the first storage tank 222, and the first liquid is filtered by the first filter 227; by setting the first pressure gauge 228, the circulation pressure of the first liquid is monitored, making the circulation flow rate of the first liquid adjustable.

[0045] In this embodiment, the first spraying mechanism 22 further includes a first drain pipe 229. The first drain pipe 229 is disposed in the first liquid storage tank 222 and is used to discharge waste liquid, impurities, etc. in the first liquid storage tank 222 to ensure the cleanliness of the first liquid. Understandably, the first liquid storage tank 222 may also be provided with an inlet (not shown) for replenishing the first liquid, a solenoid valve (not shown) disposed at the inlet, an overflow outlet (not shown) for discharging excess first liquid, a mid-level replenishment switch (not shown) for replenishing mid-level liquid, a lower limit liquid level protection switch (not shown) for interlocking pump stop and alarming at low liquid level, and an upper limit liquid level protection switch (not shown) for draining high liquid level. The first spraying mechanism 22 also includes a drain outlet (not shown) for quick-release connection with the first filter 224 and the first filter 227. These will not be described in detail in this embodiment.

[0046] Please see Figure 3In this embodiment, the second spraying mechanism 24 includes a second spray chamber 241, a second liquid storage tank 242, a second spray pump 243, a second filter 244, and a plurality of second nozzles 245. The second spray chamber 241 is disposed on the spraying transmission mechanism 21, that is, the spraying transmission mechanism 21 transports the product through the second spray chamber 241. The second liquid storage tank 242 is disposed on the spraying frame 26, and is disposed below the spraying transmission mechanism 21 and communicates with the second spray chamber 241, that is, the second liquid in the second spray chamber 241 can flow back to the second liquid storage tank 242. The second spray pump 243 is disposed on the second liquid storage tank 242, the second filter 244 is communicated with the second spray pump 243, and the plurality of second nozzles 245 are disposed in the second spray chamber 241 and are all communicated with the second filter 244. The plurality of second nozzles 245 are all disposed above the spraying transmission mechanism 21 for spraying the second liquid onto the product. The second spray chamber 241 and the second liquid storage tank 242 can both be made of stainless steel plate. The power of the second spray pump 243 is, for example, 1.1KW and the pumping pressure is adjustable. The pumping pressure of the second spray pump 243 can be from 0.1Mpa to 0.6Mpa. The second spray pump 243 is equipped with an anti-backflow device to prevent the second liquid from flowing back. The second filter 244 can filter impurities such as dust and aluminum shavings in the second liquid. The filtration accuracy of the second filter 244 is 20μ. The second nozzle 245 can be fan-shaped, and the orifice diameter of the second nozzle 245 is, for example, 1.1mm. There can be multiple second nozzles 245. For example, multiple second nozzles 245 can be divided into upper and lower layers. The upper layer has six sections, with four second nozzles 245 in each section, for a total of twenty-four second nozzles 245 in the upper layer. The second nozzles 245 in the upper layer can move closer to or further away from the spray transmission mechanism 21. The moving stroke of the second nozzles 245 in the upper layer is, for example, 50mm to 100mm. The lower layer has two sections, with four second nozzles 245 in each section, for a total of eight second nozzles 245 in the lower layer. The angle of the second nozzles 245 in the lower layer is adjustable.

[0047] Thus, by configuring the second spray chamber 241, the second liquid storage tank 242, the second spray pump 243, the second filter 244, and multiple second nozzles 245, the second spray mechanism 24 achieves the effect of spraying a second liquid onto the product. Furthermore, the second liquid can circulate between the second spray chamber 241 and the second liquid storage tank 242, improving the utilization rate of the second liquid and reducing the product cleaning cost. In addition, by configuring the second filter 244, the second liquid is filtered, preventing it from clogging the second nozzles 245 and ensuring that the second nozzles 245 can smoothly spray the second liquid.

[0048] In this embodiment, to ensure the smooth return of the second liquid in the second spray chamber 241 to the second storage tank 242, the second spray mechanism 24 further includes a second filtration pump 246, a second filter 247, and a second pressure gauge 248. The second filtration pump 246 is disposed in the second spray chamber 241, the second filter 247 is connected between the second filtration pump 246 and the second storage tank 242, and the second pressure gauge 248 is disposed between the second filter 247 and the second storage tank 242. Thus, by configuring the second filtration pump 246 and the second filter 247, the second liquid in the second spray chamber 241 smoothly returns to the second storage tank 242, and the second liquid is filtered by the second filter 247; by configuring the second pressure gauge 248, the circulation pressure of the second liquid is monitored, making the circulation flow rate of the second liquid adjustable.

[0049] In this embodiment, the second spraying mechanism 24 further includes a second drain pipe 249. The second drain pipe 249 is disposed in the second storage tank 242 and is used to discharge waste liquid, impurities, etc. in the second storage tank 242 to ensure the cleanliness of the second liquid. Understandably, the second storage tank 242 may also be provided with an inlet for replenishing the second liquid, a solenoid valve disposed at the inlet, an overflow outlet for discharging excess second liquid, a mid-level replenishment switch for mid-level replenishment, a lower limit level protection switch for interlocking pump stop and alarming at low liquid level, and an upper limit level protection switch for high-level drainage, etc. The second spraying mechanism 24 also includes a drain outlet for quick-release connection with the second filter 244 and the second filter 247, which will not be described in detail in this embodiment.

[0050] Please see Figure 1 In this embodiment, the spraying device 20 further includes a third air-blowing mechanism 27, which is disposed on the side of the first spraying mechanism 22 opposite to the first air-blowing mechanism 23. The third air-blowing mechanism 27 is used to blow air onto the product conveyed to the spraying conveying mechanism 21 to remove impurities, dust, and other impurities from the product. The third air-blowing mechanism 27 may consist of multiple nozzles. The first air-blowing mechanism 23 is used to remove impurities and dust from the product just entering the spraying device 20, ensuring that the first liquid can effectively dissolve and soften impurities such as glue and oil on the product, thus guaranteeing the cleanliness of the product.

[0051] In this embodiment, the first air-blowing mechanism 23 includes multiple first upper air blades 231 and multiple first lower air blades 232. Both the multiple first upper air blades 231 and the multiple first lower air blades 232 are connected to an external air source (not shown). The multiple first upper air blades 231 are positioned above the spray conveying mechanism 21, and at least one of the multiple first upper air blades 231 can move closer to or further away from the spray conveying mechanism 21. The multiple first lower air blades 232 are positioned above the spray conveying mechanism 21 and below the multiple first upper air blades 231. At least one of the multiple first lower air blades 232 has an adjustable angle. Both the multiple first upper air blades 231 and the multiple first lower air blades 232 are used to blow air onto the product. The number of first upper air blades 231 can be four, and the number of first lower air blades 232 can be two. Understandably, in other embodiments, the number of first upper air blades 231 and the number of first lower air blades 232 can be more or less. Thus, by setting the specific structure of the first air blowing mechanism 23 as described above, the first air blowing mechanism 23 blows air onto the product from multiple angles through the first upper air knife 231 and the first lower air knife 232, so as to ensure that the first liquid and impurities such as glue and oil dissolved and softened by the first liquid are blown off the product, thereby ensuring the cleaning quality of the product.

[0052] In this embodiment, the second air blowing mechanism 25 includes a plurality of second upper air blades 251 and a plurality of second lower air blades 252. Both the plurality of second upper air blades 251 and the plurality of second lower air blades 252 are connected to an external air source. The plurality of second upper air blades 251 are positioned above the spray conveying mechanism 21, and at least one of the plurality of second upper air blades 251 can move closer to or further away from the spray conveying mechanism 21. The plurality of second lower air blades 252 are positioned above the spray conveying mechanism 21 and below the plurality of second upper air blades 251. At least one of the plurality of second lower air blades 252 has an adjustable angle. Both the plurality of second upper air blades 251 and the plurality of second lower air blades 252 are used to blow air onto the product. The number of second upper air blades 251 can be four, and the number of second lower air blades 252 can be two. Understandably, in other embodiments, the number of second upper air blades 251 and the number of second lower air blades 252 can be more or less. Thus, by setting the specific structure of the second air blowing mechanism 25 as described above, the second air blowing mechanism 25 blows air onto the product from multiple angles through the second upper air knife 251 and the second lower air knife 252 to ensure that the second liquid on the product is blown off and to ensure the cleaning quality of the product.

[0053] In this embodiment, the drying air knife assembly 33 includes multiple upper drying air knives 331 and multiple lower drying air knives 332. Both the upper and lower drying air knives 331 are connected to the drying fans 32. The upper drying air knives 331 are positioned above the drying conveying mechanism 31, and at least one of the upper drying air knives 331 can move closer to or further away from the drying conveying mechanism 31. The lower drying air knives 332 are positioned above the drying conveying mechanism 31 and below the upper drying air knives 331. At least one of the lower drying air knives 332 has an adjustable angle. Both the upper and lower drying air knives 331 and 332 are used to blow air onto the product. The assembly can have six upper drying air knives 331 and six lower drying air knives 332, and three drying fans 32, with each fan paired with two upper drying air knives 331 and two lower drying air knives 332. Understandably, in other embodiments, the number of drying fans 32, the number of upper drying air blades 331, and the number of lower drying air blades 332 can be more or less. Thus, by setting the specific structure of the drying air blade assembly 33 described above, the drying air blade assembly 33 blows air onto the product from multiple angles through the upper drying air blades 331 and the lower drying air blades 332 to ensure the product is heated and dried, thereby ensuring the cleaning quality of the product.

[0054] In this embodiment, the drying chamber 42 includes multiple splicing panels 421, which are assembled into the drying chamber 42 according to a preset shape. At least one of the splicing panels 421 can generate heat. The drying transmission mechanism 31 passes through the drying chamber 42. For example, the drying chamber 42 can be a structure with openings at both ends and closed sides, or it can be a frame structure with openings at both ends and a king-shaped perimeter, or it can be composed of two oppositely arranged splicing panels 421. This embodiment will not elaborate further. The splicing panel 421 can be a mid-wave infrared heating plate with a heating power of 3KW. Thus, by defining the specific structure of the drying chamber 42, its shape is variable and can be modified according to actual conditions, thereby ensuring the drying effect on the product and improving the applicability of the drying chamber 42. The temperature range inside the drying chamber 42 is room temperature, for example, from 25°C to 100°C. Understandably, after the product passes through the drying device 30, there may be liquid residue. When the product with residual liquid passes through the drying chamber 42, it is further dried, and simultaneously, the cooling fan 43 dissipates heat from the product to ensure the drying effect. The drying chamber 42 can also be equipped with a temperature controller (not shown), a temperature-measuring thermocouple (not shown), etc., and the temperature inside the drying chamber 42 is adjustable from room temperature to 100℃. When the temperature inside the drying chamber 42 exceeds 100℃, the drying chamber 42 can also trigger an over-temperature alarm and activate the splicing panel 421 to stop heating, and activate the cooling fan 43 to delay shutdown, so that the temperature inside the drying chamber 42 can be lowered through the cooling fan 43.

[0055] The cleaning equipment 100 of this application embodiment, through the coordinated operation of the feeding device 10, spraying device 20, drying device 30, air-cutting device 40, and discharging device 50, can directly interface with external processing equipment to achieve product cleaning and drying. This enables online product cleaning, eliminating the need for frequent product disassembly and reassembly, as well as loading and unloading, thereby improving cleaning efficiency, reducing manual labor, and lowering labor costs. Furthermore, since product disassembly is unnecessary, the number of specialized fixtures and related tools can be reduced, thus lowering material costs.
