[0002] During the research, development and production process of dishwashers, it is necessary to test the performance parameters of the dishwasher, and the main indicator is the cleanliness of the dishes after cleaning.

[0003] The performance parameters of existing dishwashers are judged according to GB / T20290-2016. After the dishwasher and the standard machine have finished the program, the performance parameters are mostly tested by testers with the naked eye according to the standard. However, the standards of different personnel cannot be completely unified, and the naked eye cannot accurately distinguish 1mm 2 With 1.5mm 2 The performance values ​​obtained are often far from the actual ones. If there are dozens of sets of tableware to be judged during the testing process, a lot of manpower and material resources will be wasted. Summary of the invention

[0012] The third conveying device is arranged in the detection completion area and close to the second conveyor belt, and is used for receiving the pallet after the detection is completed.

[0013] In the present invention, the conveying device for the pieces to be detected includes a first transmission shaft, a first transmission wheel, a second transmission shaft, a second transmission wheel, a driving member, a chain, a transmission plate and the circulating conveying track. The circulating conveying track is in two groups and arranged at a relative interval. The first transmission shaft is arranged between the two circulating conveying tracks and is located at the upper part. The first transmission wheels are two and the two first transmission wheels are respectively connected to the two ends of the first transmission shaft. The second transmission shaft is arranged between the two circulating conveying tracks and is located at the lower part. The second transmission wheels are two and the two second transmission wheels are respectively connected to the two ends of the second transmission shaft. The chains are two and are respectively connected to the corresponding first transmission wheels and second transmission wheels. The driving member is used to drive the first transmission wheel and the second transmission wheel to rotate so as to drive the chain transmission. The transmission plates are multiple and are arranged on the chain in groups of two and are reciprocated along the O-shaped track with the chain. The support plate is horizontally supported on the two oppositely arranged transmission plates. With the above structure, multiple pieces of tableware to be detected can be conveyed to achieve continuous detection.

[0014] Preferably, the conveying plate is a triangular plate, which is an acute-angled isosceles triangular plate. The chain has a multi-section skeleton, and each skeleton is connected to form a closed loop structure by rotating the end to end through a connecting shaft. The two corners of the bottom edge of the triangular plate are respectively constrained at the two ends of the chain skeleton. The two circulating conveying tracks have a slide groove on the oppositely arranged side walls, and the tip of the triangular plate opposite to the bottom edge is rotatably connected to the slide groove. The tip of the triangular plate is rotatably connected to a clamping plate, and the inner side of the clamping plate is provided with a horizontally extending clamping groove, and the support plate is inserted into the clamping groove of the two oppositely arranged clamping plates.

[0015] The above structure fixes the conveying plate relative to a part of the chain (a section of the skeleton) and can adapt to the overall curvature of the chain when the chain turns, so that the tips of the two relative conveying plates are always at the same height, thereby utilizing the rotational connection relationship and the deadweight to keep the splint and the support plate on the splint level at all times, thereby meeting the requirement of smooth conveyance of multiple pieces of tableware in a limited space.

[0016] In order to improve the transmission stability, a rotating connection piece is arranged at the tip of the triangle plate, a shaft rotatably connected to the clamping plate is arranged on the first side of the rotating connection piece, and a first pulley cooperating with the guide of the slide groove is arranged on the second side of the rotating connection piece.

The second pulley and the third pulley can support and correct the conveying plate when it changes direction, so that the first pulley can slide smoothly into the slide groove, thereby improving the conveying stability of the conveying plate.

[0018] As an improvement, the left end of the ∩-shaped circulating conveying track is provided with a first guide bar that gradually bends from top to bottom to the right, and correspondingly, the right end of the ∩-shaped circulating conveying track is provided with a second guide bar that gradually bends from top to bottom to the left, and a conveying buffer is formed between the lower end of the second guide bar and the lower end of the first guide bar. Since the chain has a certain degree of compactness relative to the first transmission wheel and the second transmission wheel, and there is a matching gap between the chain and the transmission plate and the clamping plate, under the dead weight of each component and the object to be detected, when it is transmitted to the lower end of the circulating conveying track, shaking may occur or greater friction may occur between the chain and the slide slot.

[0023] Preferably, the first box and the second box are provided with a pre-treatment device capable of sterilizing and / or drying the inside thereof. This structure is conducive to ensuring a clean detection environment, eliminating external interference factors, and improving detection accuracy.

[0024] Specifically, the pre-treatment device includes a steam generator, a PTC heating element, and a fan. The output end of the steam generator is connected to the first box, the second box, and the third box respectively. The PTC heating element is connected to the first box, the second box, and the third box respectively through a hot air duct. The fan is used to blow hot air into the corresponding box.

With the above structure, multiple pieces of tableware to be detected can be transmitted to achieve continuous detection.

[0039] like Figure 3 As shown, the transmission plate 18 is a triangular plate, which is an acute-angled isosceles triangular plate. The chain 17 has a multi-section skeleton 171, and each skeleton 171 is connected to each other by a connecting shaft 172 to form a closed loop structure.
