[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] like Figure 1 to Figure 2As shown, the drying device of the present invention is used for drying the articles to be dried 200 placed on a tray 100, and the drying device comprises: a body 10, which is used to be arranged on a supporting base surface, and the interior of the body 10 has a closed drying space 110, which is used to accommodate the tray 100 and the articles to be dried 200; a conveying component 20, which is arranged inside the body 10 to support and drive the articles to be dried 200 placed on the tray 100 for transportation; a hot air component 30, which is arranged on a side of the body 10 away from the supporting base surface, and a heating element and a blower are arranged in the hot air component 30 to convey a drying airflow to the articles to be dried 200 in the drying space 110.

[0033] It can be seen that the present invention arranges the body 10, the conveying component 20 and the hot air component 30, and cooperates the conveying component 20 with the hot air component 30, so that the parts to be dried 200 can be automatically and continuously transported from the feed end to the drying space 110, and are efficiently dried by the drying airflow provided by the hot air component 30, which greatly improves the degree of automation of the drying process and reduces the dependence on manual operation; the heating element and the blower design in the hot air component 30 can generate hot air to ensure uniform temperature distribution in the drying space 110, avoid local overheating or incomplete drying, and improve drying efficiency and quality; effectively solves the problem of low efficiency of drying equipment for drying parts after cleaning in the prior art.

[0034] Optionally, the conveying assembly 20 is a conveying roller, which includes a plurality of transmission shafts arranged in parallel, and installation spaces are provided on both sides of the conveying roller, and rollers 210 are provided at both ends of each transmission shaft, and the plurality of rollers 210 are respectively provided in two installation spaces, and the rollers 210 are used to support the tray 100 and drive the tray 100 to move on the rollers 210. A stable and smooth moving surface is formed by the plurality of transmission shafts arranged in parallel and the rollers 210 at both ends, so that the tray 100 can move smoothly on the rollers 210, reducing friction and vibration, and improving transportation efficiency and stability; and the design of the conveying roller can withstand a higher load, ensuring that the roller can remain stable when carrying a heavier object 200 to be dried, reducing wear and extending the service life of the equipment.

[0035] like Figure 2 As shown, the drying device further includes: a driving component 40; a transmission component, the transmission component is connected to the driving component 40 to drive the transmission component to move, and the transmission component is connected to the conveying roller to drive the conveying roller to move in a predetermined direction. Through the cooperation of the driving component 40 and the transmission component, the conveying speed can be accurately controlled, the uniformity and controllability of the drying process can be ensured, and the production efficiency of the product is improved.

[0036] In one embodiment of the present aspect, the transmission component includes a first transmission sprocket, a second transmission sprocket and a transmission chain, a second transmission sprocket is provided at both ends of each transmission shaft, and a transmission chain is respectively sleeved on the second transmission sprockets at both ends of the multiple transmission shafts, wherein the first transmission sprocket is arranged on a transmission shaft of the multiple transmission shafts, and is synchronously driven with the second transmission sprockets at both ends of the corresponding transmission shaft to transmit the power of the first transmission sprocket to the corresponding second transmission sprocket and the transmission chain; and / or the driving component 40 includes a driving motor 410, a driving sprocket 420 and a driving chain, the driving motor 410 is arranged at the bottom of the body 10, the output shaft of the driving motor 410 is connected to the driving sprocket 420, and the driving chain is sleeved on the driving sprocket 420 and the first transmission sprocket to transmit the power of the driving motor 410 to the first transmission sprocket, and drive the transmission component to move, so that the conveying roller moves along a predetermined direction; and / or wherein the first transmission sprocket is arranged on a side of the corresponding transmission shaft close to the driving component 40 to transmit power to the first transmission sprocket.

[0037] Through the chain transmission mechanism of the first transmission sprocket and the second transmission sprocket, and the connection between the drive motor 410 and the drive sprocket 420, efficient and stable transmission of power is achieved. As the key to power distribution, the first transmission sprocket can evenly transmit power to the second transmission sprockets on each transmission shaft, ensuring that all raceways run synchronously and smoothly, improving the operating efficiency of the equipment and the drying quality of the workpiece; and the transmission method of the sprocket and chain in the present invention can usually reduce the noise and vibration during the operation of the equipment compared to the gear transmission, improve the comfort of the working environment, and reduce the movement and deviation of the workpiece caused by vibration, ensuring the stability of the drying process and the position accuracy of the workpiece.

[0038] like Figure 1 As shown, the hot air component 30 also includes: a first hot air component 310, which is fixed on the body 10 and located on a side away from the part to be dried 200, so as to provide hot air for drying the part to be dried 200; and / or a second hot air component 320, which is fixed on the body 10 and distributed on one side of the first hot air component 310 along the conveying direction of the part to be dried, so as to provide hot air for drying the part to be dried 200.

[0039] The provision of the first hot air component 310 and the second hot air component 320 in the present invention ensures that the workpiece 200 to be dried can receive hot air from multiple directions, thereby improving the uniformity and efficiency of drying, and can carry out hot air drying in a targeted manner in the direction of travel of the workpiece, thereby ensuring the rapid evaporation of moisture on the surface of the workpiece; through the independent control of the first hot air component 310 and the second hot air component 320, the temperature, wind speed and blowing angle of the hot air can be accurately adjusted according to the material, size and shape of the workpiece 200 to optimize the hot air distribution, ensure that each part of the workpiece can be properly dried, and reduce the problem of incomplete drying or overheating damage caused by uneven hot air distribution.

[0040] Preferably, the hot air assembly 30 further includes: a first sleeve portion 311 is provided at the air outlet of the first hot air assembly 310, the first sleeve portion 311 extends to the tray 100 and is sleeved on the side wall of the drying object 200 to dry the side wall of the drying object 200; and / or a second sleeve portion 321 is provided at the air outlet of the second hot air assembly 320, the second sleeve portion 321 extends to the top of the drying object 200 to dry the top of the drying object 200; and / or the first sleeve portion 311 and the second sleeve portion 321 are metal meshes. The provision of the first sleeve portion 311 and the second sleeve portion 321 can accurately guide the hot air to the side wall and the top of the drying object 200, especially for parts with many holes or deep holes, it can ensure that the inner and outer surfaces of the holes are fully blown by the hot air, thereby improving the uniformity and efficiency of drying.

[0041] Specifically, when the first sleeve portion 311 and the second sleeve portion 321 adopt a metal mesh structure, hot air will produce a tiny eddy effect when passing through the metal mesh, thereby increasing the penetration of the hot air, facilitating the rapid evaporation of moisture inside the holes, and reducing drying dead corners; and for diesel engine parts with a hole structure, when hot air passes through the metal mesh of the first sleeve portion 311 and the second sleeve portion 321, it can not only dry the holes, but also use the flow of hot air to take away tiny impurities or residues in the holes, thereby improving the cleanliness of the holes.

[0042] Preferably, the drying device further comprises a plurality of limit assemblies 50, which are arranged in the installation space and spaced apart along the transport direction of the dried object 200, so as to contact the side of the tray 100 and limit the moving direction of the side of the tray 100 when the tray 100 moves driven by the roller 210. The plurality of limit assemblies 50 are spaced apart along the transport direction of the dried object 200 and contact the side of the tray, so as to ensure the stable movement of the tray 100 on the roller 210 and precisely limit the moving direction of the tray, thereby avoiding uneven drying or equipment failure caused by position offset.

[0043] In an embodiment of the present invention, a rolling structure is provided in the limit assembly 50. During the movement of the tray 100, the sliding friction is replaced by rolling friction between the limit assembly and the side of the tray, thereby reducing the friction and wear between the two and extending the service life of the limit assembly and the tray.

[0044] Furthermore, the drying equipment also includes a plurality of opening and closing mechanisms 60, which are installed on the door panels 610 at both ends of the machine body 10, and each opening and closing mechanism 60 is provided with a hydraulic cylinder 620, and the output end of the hydraulic cylinder 620 is connected to the corresponding door panel 610 to open or close the door panel 610. The hydraulic cylinder 620 drives the opening and closing of the door panel 610, realizing the automatic control of the inlet and outlet of the equipment. This design reduces the need for manual operation and improves the operating efficiency and operational safety of the equipment. In addition, the use of the hydraulic cylinder 620 ensures the stability and accuracy of the opening and closing of the door panel 610, and avoids mechanical damage or safety accidents caused by the unstable opening and closing of the door panel 610.

[0045] The tight connection between the door panel 610 and the machine body 10 in the present invention can form a good sealing effect through the drive of the hydraulic cylinder 620, reduce the heat loss during the drying process, improve the thermal efficiency, and reduce the energy consumption.

[0046] like Figure 1 As shown, the drying device further includes a plurality of support columns 70, which are arranged at the bottom of the body 10 and are evenly distributed along the length direction of the body 10 to support the body 10. The even distribution of the support columns 70 ensures the stability of the device, which can remain stable even under high-load operation, is suitable for large industrial production lines, and reduces the defective product rate caused by unstable equipment.

[0047] In an embodiment of the present invention, the drying device further includes a temperature sensor and an alarm system. The temperature sensor is installed inside the body 10 and is used to monitor the temperature in the drying space 110 in real time, so that when the temperature in the drying space 110 exceeds a preset temperature, the alarm system is activated and an alarm signal is issued. The temperature sensor monitors the temperature in the drying space 110 in real time to ensure that the drying process is always within the optimal temperature range, which is very important for ensuring the drying quality of workpieces such as diesel engine parts and preventing overheating damage.

[0048] Specifically, when the temperature sensor detects that the temperature in the drying space 110 exceeds the preset safety threshold, the alarm system is immediately activated and sends out an alarm signal to remind the operator to take corresponding measures, such as reducing the output power of the hot air component or stopping the equipment operation, effectively preventing safety accidents such as equipment failure, workpiece damage or fire caused by excessive temperature.

[0049] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
