[0032] like Figures 1 to 6 As shown, the first embodiment of the present application shows a tray cleaning device, including: a base assembly 10, the base assembly 10 includes a base structure 11 and a cleaning tank structure 12, the cleaning tank structure 12 is fixed on the base structure 11, and in the first direction, both side walls of the cleaning tank structure 12 have a tray channel 121. A cleaning brush assembly 20, the cleaning brush assembly 20 includes a cleaning motor 21, a transmission shaft 22, a plurality of bevel gear structures 23 and a plurality of cleaning brushes 24, the transmission shaft 22 extends along the second direction, the plurality of bevel gear structures 23 are arranged on the transmission shaft 22, the plurality of bevel gear structures 23 are arranged at intervals along the axial direction of the transmission shaft 22, the plurality of cleaning brushes 24 are mounted on the plurality of bevel gear structures 23 in a one-to-one correspondence, and the plurality of bevel gear structures 23 and the plurality of cleaning brushes 24 are both located in the cleaning tank structure 12.

[0033] By applying the technical solution of the present application, a cleaning motor can drive multiple cleaning brushes 24 for cleaning through a transmission shaft 22 and multiple bevel gear structures 23. The structure of replacing multiple motors with one cleaning motor 21 can save processing costs. In addition, the multiple cleaning brushes driven by the same cleaning motor 21 have the same rotation speed, frequency, etc., so that the consistency of cleaning quality is better. The technical solution of this embodiment effectively solves the problem of high equipment cost and poor quality consistency of cleaning trays in the prior art.

[0034] It should be noted that the first direction X and the second direction Y are perpendicular to each other, and the second direction Y corresponds to the other two side surfaces of the cleaning tank structure 12 .

[0035] like Figure 1 , Figures 4 to 6As shown, in the technical scheme of the first embodiment, each bevel gear structure 23 includes a driving bevel gear 231, a transmission rod 232 and a driven bevel gear 233, the cleaning tank structure 12 includes a cleaning tank and a fixed beam arranged in the cleaning tank, the fixed beam extends along the second direction, each transmission rod 232 is rotatably mounted on the fixed beam, each driven bevel gear 233 is mounted on the upper end of each transmission rod 232 in a one-to-one correspondence, each cleaning brush 24 is mounted on the lower end of each transmission rod 232 in a one-to-one correspondence, and multiple driving bevel gears 231 are arranged on the transmission shaft 22 at intervals, and each driven bevel gear 233 is meshed with each driving bevel gear 231 in a one-to-one correspondence. By adopting the bevel gear structure 23, the rotation with the horizontal axis as the rotation axis can be converted into the rotation with the vertical axis as the rotation axis. By arranging multiple driving bevel gears 231 on a transmission rod 232, it is possible to realize the simultaneous rotation of multiple driving bevel gears 231, which is transmitted to the work of multiple cleaning brushes 24. The above structure is compact and easy to operate.

[0036] It should be noted that a bearing is provided between the transmission rod 232 and the fixed beam, the outer ring of the bearing is interference fit or welded with the fixed beam, and the transmission rod 232 is interference fit with the inner ring of the bearing. The inner wall of the driven bevel gear 233 has a groove, the outer wall of the transmission rod 232 has a groove, and the transmission pin block is located in the two grooves, so that the driven bevel gear 233 transmits the rotation to the synchronous rotation of the transmission rod 232.

[0037] like Figure 1 As shown, in the technical solution of the first embodiment, the cleaning brush assembly 20 includes a first cleaning brush assembly and a second cleaning brush assembly, the first cleaning brush assembly and the second cleaning brush assembly are arranged at intervals in the first direction, and the cleaning brushes 24 of the first cleaning brush assembly and the cleaning brushes 24 of the second cleaning brush assembly are arranged in an interlaced manner. In this way, the cleaning of the tray is more comprehensive. There will be gaps between adjacent cleaning brushes 24 on the same cleaning brush assembly 20, and the above gaps can be cleaned by arranging two rows (second direction Y) of cleaning brushes 24.

[0038] It should be noted that the gap between two adjacent cleaning brushes 24 is less than or equal to the diameter of the cleaning brush 24. The cleaning brush 24 of the first cleaning brush assembly is located between two adjacent cleaning brushes 24 of the second cleaning brush assembly, that is, through the arrangement of the cleaning brushes 24 of the first cleaning brush assembly and the cleaning brushes 24 of the second cleaning brush assembly, there is no dead angle after the tray is cleaned along the first direction, and the gaps between adjacent cleaning brushes 24 can also be covered.

[0039] like Figures 1 to 4As shown, in the technical solution of the first embodiment, the tray cleaning device further includes: a spray assembly 30, the spray assembly 30 includes a power pump structure and a spray head structure, the spray head structure is arranged in the cleaning tank structure 12, and the power pump structure is connected to the spray head structure. The spray assembly 30 can spray cleaning liquid to the cleaning position, and the cleaning liquid can wash the impurities to be cleaned away from the tray on the one hand, and can clean the tray more cleanly on the other hand.

[0040] like Figure 4 As shown, in the technical solution of the first embodiment, in the first direction X, both sides of each cleaning brush assembly 20 are provided with a spray head structure, each spray head structure extends along the second direction Y, and each spray head structure includes a plurality of spray heads, each spray head is provided in one-to-one correspondence with each cleaning brush 24. The above-mentioned spray head structure and the cleaning brush assembly 20 have a good coordination effect, the spray head structure fully covers the cleaning brush assembly 20 from the length (second direction Y), and the spray head structure also cleans from both sides of the cleaning brush assembly 20, so that the spray head structure can flush the impurities cleaned by the cleaning brush assembly together.

[0041] It should be noted that, when working, the cleaning brush 24 of the cleaning brush assembly 20 brushes the tray 100, and the cleaning liquid of the spray head structure rinses the impurities swept by the brush, and the cleaning liquid and impurities fall into the cleaning tank structure 12. The cleaning tank has a liquid outlet at the bottom, and the liquid outlet is connected to the power pump structure. The liquid in the liquid outlet flows back to the collection tank through the filtering structure, and the power pump structure transports the cleaning liquid in the collection tank for cleaning, forming a self-circulating cleaning of the cleaning liquid, saving the cleaning liquid.

[0042] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the pallet cleaning device further includes a lifting assembly 40, which is fixed on the base structure 11 and connected to the cleaning brush assembly 20, and the cleaning brush assembly 20 is connected to the base structure 11 so as to be movable up and down. The setting of the lifting assembly 40 enables the pallet cleaning device to adapt to pallets 100 of different thicknesses. When the pallet is higher, the cleaning brush 24 can be raised by the lifting assembly 40, and when the pallet is lower, the cleaning brush 24 can be lowered by the lifting assembly 40.

[0043] It should be noted that the vertical distance that the cleaning brush 24 is raised or lowered is not large. The cleaning motor 21 is fixed to the lifting assembly 40, and the cleaning brush assembly 20 has a slide groove on the component located outside the cleaning tank structure 12, and a slide rail is provided on the base structure, and the slide rail extends vertically, and the slide groove and the slide rail cooperate. The cooperation of the slide rail and the slide groove makes the movement accuracy of the cleaning brush assembly 20 higher and the movement more stable. The above-mentioned fixation can be welded or detachably connected by fasteners.

[0044] like Figure 3As shown, in the technical solution of the first embodiment, the lifting assembly 40 includes a lifting motor, a turbine and a screw structure, the lifting motor is fixed on the base structure 11, the turbine is installed at the output end of the lifting motor, the screw structure is connected to the cleaning brush assembly 20, and the turbine is meshed with the screw structure. The above transmission makes the movement of the cleaning brush assembly 20 relatively stable, because the vertical distance of the cleaning brush assembly 20 rising or falling is not large, and this effect can be well achieved through the worm gear structure.

[0045] The lifting assembly 40 is four groups, and the screw structure is connected to the transmission shaft 22, or the screw structure is connected to the cleaning motor 21. When the screw structure is connected to the transmission shaft 22, a support plate is provided on the screw structure, and a bearing is provided between the transmission shaft 22 and the support plate. The support plate is fixedly connected to the screw structure, and the two side walls of the cleaning tank structure in the second direction have long holes, which extend vertically. The transmission shaft 22 passes through the long holes, and the transmission shaft 22 can move vertically in the long holes. The lifting assembly 40 can be hydraulically driven, pneumatically driven or an electric push rod, etc. The lifting assembly 40 can also be omitted so that the pallet cleaning device only cleans pallets 100 of one thickness.

[0046] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the tray cleaning device further includes a transmission assembly 50, and the transmission assembly 50 is arranged on the cleaning tank structure 12. The arrangement of the transmission assembly 50 enables the tray 100 to be transmitted through the transmission assembly 50, which greatly reduces the labor intensity.

[0047] like Figure 1 and Figure 4 As shown, in the technical solution of the first embodiment, the transmission assembly 50 includes a transmission motor, a transmission shaft and a plurality of friction wheels, the transmission motor is fixed on the cleaning tank structure 12, the transmission shaft is rotatably mounted on the cleaning tank structure 12, and the plurality of friction wheels are fixed at intervals on the circumferential outer side of the transmission shaft. The above structure is easy to operate. The transmission assembly 50 is located at the lower part of the tray 100.

[0048] Teleport

[0049] In the technical solution of this embodiment, the tray cleaning device further includes a control component, which includes a control body and a swing monitor, the cleaning brush assembly 20 and the swing monitor are electrically connected to the control body, and the swing monitor is installed on the base assembly 10. The swing monitor can monitor the displacement of the tray 100 in the second direction Y and other directions when it moves along the first direction X.

[0050] The difference between the technical solution of the second embodiment and the first embodiment is that the cleaning brush assembly 20 is four groups, the first cleaning brush assembly and the third cleaning brush assembly correspond to each other, the first cleaning brush assembly is located at the upper part of the tray 100, and the third cleaning brush assembly is located at the lower part of the tray 100. The second cleaning brush assembly is located at the upper part of the tray 100, and the fourth cleaning brush assembly is located at the lower part of the tray 100. In this way, the upper and lower surfaces of the tray 100 can be cleaned. When lifting and lowering, only the cleaning brush assembly at the upper part of the tray 100 needs to be moved.

[0051] From the above, it can be seen that the application uses a PLC (programmable logic controller) to control the servo lifting disc brush and a brushless DC motor to control the rotation of the disc brush. Through the PLC control system (control body), the up and down movement of the servo lifting disc brush can be accurately controlled to adapt to the cleaning of trays at different heights. At the same time, the brushless DC motor controls the rotation of the disc brush, so that the disc brush (cleaning brush 24) can clean the tray 100 at an appropriate speed and direction.

[0052] Structure: The device includes a servo lifting disc brush device and a disc brush device controlled by a brushless DC motor. The servo lifting disc brush device includes a servo lifting mechanism and a disc brush. The servo lifting mechanism can accurately control the lifting and lowering movement of the disc brush through the PLC control system. The disc brush device includes a brushless DC motor and a disc brush. The brushless DC motor can accurately control the rotation speed and direction of the disc brush through the control system.

[0053] The connection relationship between the components: the servo lifting disc brush device is connected to the upper part of the cleaning equipment to ensure that the disc brush can move in the up and down directions. The disc brush device controlled by the brushless DC motor is connected to the servo lifting disc brush device to ensure that the disc brush can move in the rotation direction.

[0054] Function: The servo brush lift is controlled by PLC, which can be precisely adjusted according to the height of the pallet to accommodate the cleaning of pallets at different heights. The brush is controlled by a brushless DC motor, which can precisely control the rotation speed and direction of the brush to ensure thorough cleaning of the pallet. The structure and connection of the entire equipment enable the cleaning process to efficiently and accurately clean the pallet, improving the cleaning effect and product quality.

[0055] The present application has the following beneficial effects: Saving energy and water resources: Traditional cleaning equipment usually requires a large amount of water and energy to complete the cleaning process, while the device can significantly reduce the consumption of water and energy by optimizing the cleaning process and using an efficient spray system.

[0056] Improve cleaning speed and production capacity: Traditional equipment may have slow cleaning speed due to manual operation or poor cleaning effect, while this device is equipped with an efficient cleaning mechanism and automatic control system, which can greatly improve the cleaning speed and production capacity and improve production efficiency.

[0057] Improve hygiene standards and product quality: Traditional equipment may lead to lower product hygiene standards due to incomplete cleaning or the presence of residual substances. This device can improve product hygiene standards and quality by thoroughly cleaning the dirt and residual substances on the surface of the tray, complying with relevant industry specifications and standards.

[0058] Reduce pollution and environmental impact: Traditional cleaning equipment may produce a large amount of wastewater and pollutants, which have a negative impact on the environment. This device uses an efficient filtration and treatment system to minimize the discharge of pollutants.

[0059] In summary, this invention not only solves the problems of high labor costs, poor adaptability and poor cleaning effects of traditional pallet cleaning equipment, but also has multiple advantages of saving energy and water resources, increasing cleaning speed and production capacity, improving hygiene standards and product quality, and reducing pollution and environmental impact.
