[0020] The present invention also provides a working principle of a fully automatic waterless tray cleaning and closing machine, comprising the following steps:

[0021] S1) Conveying pallet: Press the corresponding control switch on the control switch group, the fifth cylinder drives the stop plate to move upward, and the pallet to be cleaned is placed on the conveyor belt. The first motor drives the first pulley to rotate, and the second pulley is driven to rotate through the first transmission belt, thereby driving the roller and the first rotating shaft to rotate together, thereby driving the conveyor belt to rotate, so that the pallet to be cleaned moves to the left, and stops moving when the pallet to be cleaned contacts the fourth proximity switch on the stop plate;

[0022] S2) Clamping the pallet: Press the corresponding control switch on the control switch group, and the third cylinder drives the first clamping plate to move inward and clamp the pallet;

[0023] S3) Positioning the pallet: Press the corresponding control switch on the control switch group, the first servo motor controls the third pulley to rotate through the planetary reducer, and drives the fourth pulley to rotate through the second transmission belt, so that the mounting block, the fourth fixed block, and the seventh fixed plate move forward together, and the movable block stops moving after contacting the third proximity switch, thereby positioning the position of the pallet to be cleaned;

[0024] S4) Dust the tray: Press the corresponding control switch on the control switch group, the first cylinder drives the second fixed plate to move downward, and drives the third fixed plate to move downward together through the first limit rod until the rubber plate is located on the inner side of the tray to be cleaned, the first servo motor controls the third pulley to rotate through the planetary reducer, and drives the fourth pulley to rotate through the second transmission belt, so that the dust box moves back and forth through the mounting block, the fourth fixed block and the seventh fixed plate. While the dust box moves back and forth, the second rotating shaft and the roller brush are driven to rotate together through the gear, and the roller brush cleans the debris in the tray. At the same time, the vacuum pump exhausts the vacuum storage through the exhaust pipe. The air in the dust box is extracted, and the pressure in the vacuum dust storage box is reduced at this time, and the debris in the dust box is transported to the dust storage frame through the second fixed pipe and the dust conveying hose. The filter plate can prevent the vacuum pump and the exhaust pipe from further extracting the debris, which is convenient for centralized processing. While the dust box moves back and forth, the sixth cylinder drives the seventh fixed block to rotate back and forth, so that the dust box can be tilted in different directions during the movement, and the inner side of the tray is further scraped by the rubber plate, thereby improving the cleaning effect of the tray. When dusting the tray, impurities are cleaned by driving the roller brush to rotate in two different ways, thereby improving the practicality of the present invention.

[0025] S5) Move the cleaned pallet: press the corresponding control switch on the control switch group, the fifth cylinder drives the stop plate to move up and down, and continues to drive the pallet to move to the left through the conveyor belt. At the same time, the rodless cylinder drives the fifth fixed plate, the connecting plate, the second cylinder and the fourth fixed rod to move to the left together, and senses whether there is a pallet through the laser sensor. When the laser sensor senses that there is a pallet, the laser sensor transmits a signal to the control switch group, and the control switch group controls the second cylinder and the fourth cylinder to operate. Through the cooperation of the second cylinder and the fourth cylinder, and through the second clamping plate, the cleaned pallet is clamped. By setting an optical fiber sensor to sense whether there is a pallet clamped in the second clamping plate, the rodless cylinder drives the cleaned pallet to move to the left through the corresponding control switch on the control switch group;

[0026] S6) Collect the cleaned pallets: When the cleaned pallets are located directly above the sixth fixed plate, press the corresponding control switch on the control switch group, and place the cleaned pallets on the supporting plate by controlling the fourth cylinder. The lifting position of the sixth fixed plate is limited by setting the first proximity switch and the second proximity switch.

[0027] Compared with the prior art, the invention has the following beneficial effects: the fully automatic waterless tray cleaning and closing machine has the following advantages:

[0028] 1. A first transmission device is provided to transport the tray to be cleaned, a first lifting device is used to lift the second transmission device, a second power transmission device is provided to drive the dust box to move forward and backward, a dust box is provided to collect the debris inside the tray, and a vacuum dust storage box is provided instead of water dust storage, thereby saving the use cost. It is simpler to operate than manual water washing, has low labor intensity, small workload and higher work efficiency.

[0029] 2. Conveyor belts made of different materials are used to avoid scratches on the pallet during cleaning. A rubber plate is provided to seal the bottom side of the dust box on the one hand, and to scrape the inner side of the pallet on the other hand. The first proximity switch and the second proximity switch are provided to limit the lifting position of the sixth fixed plate. The third proximity switch is provided to facilitate positioning of the pallet to be cleaned. The stop plate and the fourth proximity switch are provided to enable the pallet to be cleaned to reach a predetermined position.

[0030] 3. The vacuum pump extracts the air in the vacuum dust storage box through the exhaust pipe. At this time, the pressure in the vacuum dust storage box is reduced, and the debris in the dust box is transported to the dust storage frame through the second fixed pipe and the dust conveying hose. The filter plate can be prevented from further extracting the debris by the vacuum pump and the exhaust pipe, which is convenient for centralized processing. The detachable dust storage frame is provided to facilitate the processing of the collected debris, which is highly practical. The fourth cylinder and the second clamping plate are provided to facilitate the clamping of the cleaned tray and place the cleaned tray on the upper side of the supporting rod. The present invention uses gas dust suction instead of water dust removal, which is more convenient to use, has higher cleaning efficiency and high safety. BRIEF DESCRIPTION OF THE DRAWINGS
