[0016] Among them, the upper end of conveying belt main body 2 is fixedly connected with multiple placing seats 3, placing seat 3 is made of polyurethane material, which not only reduces the overall weight but also has good impact resistance. The upper end of the plurality of placing seats 3 is provided with two clamping groups, and the plurality of placing seats 3 are placed with plastic valve main bodies 5. The plurality of clamping groups are composed of two clamping plates 4. One clamping plate 4 in the same clamping group is fixedly connected to the upper end of the placing seat 3, and the other clamping plate 4 in the same group is slidingly connected to the upper end of the placing seat 3. Arc-shaped grooves are formed in the side walls of the two clamping plates 4 in the same group. The curvature of the arc-shaped groove is specially designed to perfectly fit the pipe connection part of the plastic valve main body 5. One end of the plastic valve main body 5 at the corresponding position is connected to the arc-shaped groove.

[0017] Among them, the two clamping plates 4 in the same clamping group are jointly provided with a sliding device and a positioning device. The two devices work together to achieve precise control and rapid adjustment of clamping force. The sliding device includes a fixed seat 11 fixedly connected to the side wall of one of the clamping plates 4. The fixed seat is quenched to ensure long-term use without wear. Two rotating frames are fixedly connected to the upper end of the fixed seat 11. The rotating frames are made of aluminum alloy material, which ensures strength while significantly reducing the weight of the moving parts. Two pulleys 14 are rotatably arranged at the two rotating frames. The pulleys 14 are made of wear-resistant nylon material and are equipped with double-row deep groove ball bearings. The rotating resistance is less than 0.1 N.m.

[0018] Specifically, the positioning device includes a positioning post 12 fixedly connected to the side wall of one of the clamping plates 4 in the same group. A magnetic sheet is fixedly connected to the end of the positioning post 12. A sleeve 13 is fixedly connected to the side wall of the other clamping plate 4 in the same group. The inner wall of the sleeve is mirror-polished, and the clearance between the sleeve and the positioning post is controlled within 0.05mm. Another magnetic sheet is fixedly connected to the inner wall of the sleeve 13. The positioning post 12 is mated inside the sleeve 13. The two corresponding magnetic sheets attract each other. Both magnetic sheets are electromagnetic sheets, and the power is turned on and off by PLC control.

[0019] It is worth mentioning that a partition 8 is fixedly connected to the inner wall of the main body 1 of the cleaning tank. The partition is 6mm thick and adopts a double-layer hollow structure, which reduces weight and improves sound insulation. A lifting partition 9 is slidably installed through the lower end of the partition 8. The edge of the lifting partition 9 is embedded with a silicone sealing strip to effectively prevent water and air from crossing. The lifting partition 9 is connected to the partition 8 via a hydraulic rod. The hydraulic system operates at a pressure of 5MPa, and the lifting speed can be controlled within the range of 10-100mm / s. The partition 8 is located between the drying fan 6 and the cleaning spray plate 10. This layout forms independent cleaning and drying areas, ensuring that the various processes do not interfere with each other.

[0020] In this utility model, the sliding clamp 4 in the clamping assembly is opened to place the plastic valve body 5 on it, and then the clamp 4 is closed so that the positioning post 12 at the corresponding position is inserted into the sleeve 13, so that the electromagnetic plate at the corresponding position can be attracted by electromagnetic force (a sealing ring in the prior art is provided between the positioning post 12 and the sleeve 13, so that water will not enter after docking). Both ends of the plastic valve body 5 are lifted by the pulley 14. The cleaning water sprayed by the cleaning spray plate 10 will impact the plastic valve body 5, causing it to rotate between the two clamping assemblies. The corresponding pulley 14 can reduce friction and allow the plastic valve body 5 to rotate, reducing cleaning dead corners. Similarly, when the plastic valve body 5 is moved to the lower end of the drying fan 6 by the conveyor belt body 2 and the placement seat 3, the hot airflow of drying can drive the plastic valve body 5 to rotate between the two clamping groups, which speeds up the drying process. When the internal components of the cleaning box body 1 are working, the corresponding lifting partition 9 will be lowered by the hydraulic rod in the prior art, thereby playing a role in isolation and avoiding mutual interference.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
