[0062] Example

[0063] Please refer to Figure 1 、 Figure 2 and Figure 3As shown, this embodiment provides a cleaning device, including a frame 10, a rinsing mechanism 20, a drying mechanism 30, and a control box 40. The control box 40 can be a computer, a control box 40, or an operating platform. The rinsing mechanism 20 and the drying mechanism 30 are electrically connected to the control box 40, and the chain conveyor 101 is electrically connected to the output end of the control box 40. In this way, after the cleaning device is turned on, the rinsing mechanism 20 and the drying mechanism 30 are also turned on and operated, and the workpieces are transported by the chain conveyor 101, and the cleaning and drying effects are sequentially performed, thereby achieving the purpose of automated cleaning.

[0064] Specifically, a chain conveyor 101 and a tunnel-type protective cover 102 are provided on the top surface of the frame 10. The starting section of the chain conveyor 101 is provided at one end of the frame 10 and forms a loading station 103, and the end section of the chain conveyor 101 is provided at the other end of the frame 10 and forms an unloading station 104; a first gate 105 is provided on the inlet and outlet ends of the protective cover 102, that is, a first gate 105 is installed at the inlet end of the protective cover 102, and a first gate 105 is also installed at the outlet end of the protective cover 102, and the two ends of the tunnel-type protective cover 102 are closed by the first gate 105.

[0065] Furthermore, the flushing mechanism 20 is located at the starting section of the protective cover 102 and is set on the frame 10. The flushing mechanism 20 includes a water pipe 201 and a plurality of spray branches 202. The design of the chain conveyor 101 makes the middle position a conductive structure (that is, the chain conveyor 101 has symmetrical chains at both ends, and the fixture rack 70 for placing the workpiece is installed on it). In this way, the spray branches 202 can be designed on the top and bottom surfaces of the chain conveyor 101 to clean the workpiece from top to bottom and from bottom to top. It is also possible to install nozzles in different directions on the spray branches 202 to achieve the purpose of cleaning.

[0066] Furthermore, a drying mechanism 30 is located at the end of the protective cover 102 and is mounted on the frame 10. The drying mechanism 30 includes a heating element 301 for electrically generating heat or a fan for blowing hot air, and an air supply duct connected to the fan, which uses hot air to dry the workpiece. A second gate 50 is provided between the rinsing mechanism 20 and the drying mechanism 30. The heating element 301 can be an electric heating rod to quickly dry the cleaned workpiece, thereby improving cleaning efficiency.

[0067] Specifically, along the conveyor chain 101, the material is sequentially loaded at the loading station 103, cleaned by the rinsing mechanism 20, dried by the drying mechanism 30, and unloaded at the unloading station 104, completing the required cleaning process. The rinsing mechanism 20 and drying mechanism 30 are housed within a protective cover 102, creating a relatively enclosed space for cleaning and drying operations, ensuring safe operation. Furthermore, integrated and automated control via the control box 40 enhances operational convenience. Furthermore, each process is separated by a gate, preventing interference or impact between processes and improving operational stability.

[0068] like Figure 1 As shown, in this embodiment, a water storage tank 106 is provided on the top surface of the frame 10, and the chain conveyor 101 is positioned above the water storage tank 106. This allows for the centralized discharge of water dripping from the washing or conveying process. To minimize the impact on the drying area, the water storage tank 106 can be separated below the drying mechanism 30, or a separate water storage tank 106 can be designed to prevent moisture from affecting the drying area.

[0069] like Figure 4 、 Figure 5 and Figure 6 As shown, this embodiment further includes a filtering mechanism 60 , which includes a water storage tank 61 , a filtering chamber 62 and a heater 63 . The water storage tank 61 is provided with an outlet water tank 611 and multiple water tanks 612 in sequence according to the direction of water flow. A filter unit 613 is provided between two adjacent water tanks 612, and a water supply pipe leading out of the outlet water tank 611 is provided on the output end of the filter unit 613 on the last water tank 612; the filter chamber 62 is provided at the top of the outlet water tank 611, and a water inlet 621 connected to the water storage tank 106 is provided in the middle or top of the filter chamber 62, and a water outlet 622 connected to the outlet water tank 611 is provided at the bottom of the filter chamber 62, and a filter frame 623 that can be engaged or removed is provided between the water inlet 621 and the water outlet 622 in the filter chamber 62; a filter pump 614 connected to the filter unit 613 on the adjacent water tank 612 is provided on the outlet water tank 611; the heater 63 is provided on the last water tank 612.

[0070] Specifically, cleaned water from the water tank 106 is discharged into the filter chamber 62 through the water inlet 621. After passing through the filter frame 623 for the first filtration (removing large impurities such as metal debris or particles in the water), the water enters the outlet trough 611 of the water storage tank 61 through the water outlet 622, thus completing the first filtration effect. Subsequently, it undergoes a second filtration through the filter unit 613. The number of water tanks 612 can be designed according to the specific requirements of the parts or equipment, and the filter units 613 can be used to form a multi-stage filtration system. Finally, the water is discharged through the water supply pipe.

[0071] The water supply pipe can be connected to the water tank of the cleaning machine to realize the recycling of water. The water source that has been filtered multiple times can filter out impurities (such as dust particles in the water) to ensure the cleanliness of the water source, ensure the flushing effect, and improve practicality.

[0072] Furthermore, heating can be performed in the last water tank 612 by a heater 63 , which can be a heating rod. The water source is heated by electricity to control the water temperature in the water tank 612 , so as to adapt to different environments or parts of different materials and improve practicality.

[0073] Furthermore, if Figure 5 As shown, in this embodiment, there are two multiple water tanks 612, and the two water tanks 612 are arranged as a primary water tank 6121 and a secondary water tank 6122 in sequence according to the water flow direction; there are two groups of filter units 613, one group of filter units 613 is a primary filter unit 6131 and is arranged between the primary water tank 6121 and the outlet water tank 611; one filter unit 613 is connected and arranged between the primary water tank 6121 and the outlet water tank 611, and the other group of filter units 613 is a secondary filter unit 6132 and is arranged between the primary water tank 6121 and the secondary water tank 6122, and the heater 63 is arranged on the secondary water tank 6122.

[0074] Specifically, two water tanks 612 can be designed, and after adding the outlet water tank 611, three water tanks 612 can be separated in the water reservoir 61. In this way, the first stage of filtration is completed by the filter chamber 62, the first stage filtration unit 6131 is the second stage of filtration, and the second stage filtration unit 6132 is the third stage of filtration. The water is filtered three times to achieve the purpose of complete filtration.

[0075] Furthermore, if Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment, the first-level filter unit 6131 includes a filter circulation pump 6133 and a filter barrel 6134, and the secondary filter unit 6132 has the same structural arrangement as the first-level filter unit 6131; the filter barrel 6134 of the first-level filter unit 6131 is arranged between the filter pump 614 and the first-level water tank 6121, and the filter circulation pump 6133 of the first-level filter unit 6131 is arranged between the first-level water tank 6121 and the filter pump 614 of the secondary filter unit 6132; the output end of the filter pump 614 of the secondary filter unit 6132 is connected to the secondary water tank 6122, and the filter circulation pump 6133 of the secondary filter unit 6132 is arranged between the secondary water tank 6122 and the water supply pipe.

[0076] Specifically, the filter circulation pump 6133 is turned on to suck the water from the water tank 612 or draw the water out of the water tank 611 and transport it to the filter barrel 6134. The water in the previous water tank 612 is filtered and then transported to the next water tank 612. In this way, the water is filtered through multiple stages of water tanks 612 to ensure that the water is completely filtered or meets the standards for reuse, thereby achieving the purpose of multi-stage filtration.

[0077] like Figure 5 and Figure 6 As shown, in this embodiment, liquid level gauges, which may be float level gauges, may be installed on the water tank 612, the outlet water tank 611, and the filter tank 62. The liquid level gauges detect the water level, allowing the operator to observe the water level in each water tank 612 and the filter tank 62 through the liquid level gauges to ensure that the water level is within a safe range. If the water level exceeds the set range (i.e., the water level is too high or too low), the water circulation mechanism and the cleaning machine can be shut down for timely maintenance to improve safety.

[0078] like Figure 1 、 Figure 7 and Figure 8 As shown, in this embodiment, a plurality of jig frames 70 are arranged at equal intervals on the chain conveyor 101, and the jig frame 70 includes a front frame 71, a rear frame 72, a first limiting column 73 and a second limiting column 74. The front frame 71 is provided with a horizontal plate 711 and a vertical plate 712 arranged at an angle to the horizontal plate 711, and at least two symmetrical first positioning holes 713 are provided on both ends of the horizontal plate 711; the rear frame 72 is provided with a horizontal plate 721 and a vertical plate 712 with the same structural arrangement as the horizontal plate 711 and the vertical plate 712 of the front frame 71. At least two symmetrical second positioning holes 723 are provided on both ends of the baffle 722 and the horizontal plate 721; multiple pairs of first limiting columns 73 are provided, and multiple pairs of first limiting columns 73 are relatively arranged on the transverse plate 711 and the horizontal plate 721; multiple pairs of second limiting columns 74 are provided, and multiple pairs of second limiting columns 74 are relatively arranged on the transverse plate 711 and the horizontal plate 721; multiple pairs of first limiting columns 73 and second limiting columns 74 are alternately arranged, and the tops of the first limiting columns 73 and the second limiting columns 74 are provided with arc chamfers or ball head structures.

[0079] In this embodiment, both the front frame 71 and the rear frame 72 are L-shaped steel plates, with first and second limiting posts 73 and 74 mounted on the corresponding transverse plates 711 and horizontal plates 721. Alternating first and second limiting posts 73 and 74 allow for different products to be accommodated, for example, pairs of products to facilitate storage and counting, etc. The curved chamfers or ball-end structures on the tops of the first and second limiting posts 73 and 74 effectively prevent scratches on workpieces, improving protection.

[0080] When in use, the front end frame 71 is installed on the sprocket conveyor belt through the first positioning hole 713 and the bolt, and the rear end frame 72 is installed on the sprocket conveyor belt through the second positioning hole 723 and the bolt according to the length of the workpiece. In this way, the product can be placed on the relative first limiting column 73 and the relative second limiting column 74, and then transported to the cleaning area for cleaning.

[0081] Because there is a space between the front frame 71 and the rear frame 72, combined with a hollow sprocket conveyor belt (that is, a structure that is conductive up and down in the middle), a flushing nozzle facing from the bottom can be designed, and then combined with flushing nozzles at different angles on the top surface, a multi-directional flushing effect can be achieved, which greatly reduces blind spots in flushing and improves practicality.

[0082] like Figure 1 As shown, in this embodiment, light curtain detectors 107 are provided on the inlet and outlet ends of the protective cover 102. The light curtain detector 107 (the model may be a grating light curtain of EA5E1800Q or a detection light curtain of GAE) is provided in the direction of the first gate 105, so that the entry and exit of the product can be detected. Specifically, after using the detection light curtain, when the product to be cleaned enters the protective cover 102 for cleaning, the first gate 105 can be automatically opened, which greatly improves production efficiency. Specifically, the feed port detection light curtain is composed of a group of transmitters and receivers. The transmitter transmits a group of infrared light beams, and the receiver includes many light sensors. When material enters, it blocks the space between the transmitter and the receiver. The receiver cannot receive the complete signal and generates a signal. The lifting unit is turned on by the controller, so that the gate rises and opens the opening, thereby achieving the purpose of automatically opening or closing the gate to improve production efficiency.

[0083] Furthermore, if Figure 3 As shown, in this embodiment, the first gate 105 and the second gate 50 have the same structural design, and the gate includes a door frame, a base, and a switch gate. The gate divides the tunnel-type protective cover 102 into three parts, namely, the top of the door frame separates the top of the tunnel, the base separates the bottom of the tunnel, and the switch gate opens or closes the opening on the door frame, thereby achieving the effect of dividing the tunnel. The multiple gates can separate the different processes in the cleaning equipment one by one to prevent mutual interference between different processes. At the same time, the transition distance between different processes can be reduced, reducing the equipment's occupied space and improving practicality.

[0084] like Figure 1 、 Figure 2 and Figure 3As shown, in this embodiment, an air blowing mechanism 80 is disposed between the flushing mechanism 20 and the drying mechanism 30. The air blowing mechanism 80 comprises an air supply pipe and multiple branch air pipes, each of which is equipped with multiple air outlet nozzles. An air pump or blower is connected to the air supply pipe, which then diverts the air to the branch air pipes and blows it out through the air outlet nozzles to blow air over the cleaned workpiece, removing moisture from the workpiece surface. This reduces the drying time of the drying mechanism 30 and improves drying efficiency.

[0085] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, a cooling station 90 is provided between the drying mechanism 30 and the outlet end of the protective cover 102. A ventilation duct can be designed on the cooling station 90 to achieve rapid air cooling of the dried product so as to remove the workpiece and improve production efficiency.

[0086] like Figure 1 As shown, in this embodiment, a plurality of observation windows 100 are provided on the outer surface of the protective cover 102. Through the observation windows 100, the cleaning status of the workpiece can be checked from time to time, and the internal status of the equipment can also be understood so as to perform timely shutdown maintenance and improve practicality.

[0087] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
