Description

Hopper cleaning machine capable of automatically taking and placing cover and automatically opening and closing valve Technical Field The utility model relates to the field of cleaning machines, in particular to a hopper cleaning machine capable of automatically taking and placing a cover and automatically opening and closing a valve. Background In industrial production, the hopper is used as a common device for storing and conveying materials, and the cleanliness of the hopper is important for the quality of products and the production safety. The regular cleaning of the hopper is a necessary measure for ensuring the smooth production process and preventing the cross contamination of materials. The patent application number of China is CN202121703109.3, which discloses a medicinal hopper cleaning machine, belonging to the field of medicinal appliance cleaning devices. The medicinal hopper cleaning machine comprises a frame body for placing a medicinal hopper, a water tank provided with a water storage cavity, a water pump, a high-pressure spray head and a water source, wherein the frame body is rotatably connected to the water tank and communicated with the water tank, the water pump is arranged on one side of the water tank, and the high-pressure spray head is arranged above the frame body and is connected with the water source through an external water pipe. Existing hopper cleaning techniques and equipment suffer from a number of limitations, and conventional hopper cleaners typically require a significant amount of manual operation. In the links of the hopper entering and exiting the cleaning chamber, manual carrying or simple conveying equipment is often relied on for assistance, so that the efficiency is low, the hopper is easy to collide and damage due to human misoperation, and the service life and the subsequent use precision of the hopper are influenced. And the labor intensity of manual handling is high, and the labor cost is high and the cleaning timeliness is difficult to ensure under the scene of mass production. In terms of cap taking and cap closing operations, the existing cleaning machine cannot realize automation. The worker needs to manually detach and install the hopper cover, and the process is time-consuming and labor-consuming, and can also influence the subsequent cleaning effect and the tightness during material storage due to the fact that the hopper cover is not tightly sealed due to improper operation. In addition, in the manual cover taking and placing process, the contact between the hand and the hopper cover can cause secondary pollution, which is not beneficial to keeping the cleanliness of the hopper. For the valve on the hopper, the existing cleaning machine also lacks the function of automatically opening and closing the valve. Before cleaning, the valve needs to be manually opened, and after cleaning is completed, the valve is manually closed, so that the complexity of the cleaning process and the manual intervention link are increased. And the condition that the valve is not opened or closed in place possibly exists in manual operation, so that the discharge of the cleaning liquid and the normal use of a subsequent hopper in the cleaning process are affected. In terms of cleaning and drying, most of the existing cleaning machines can only clean a hopper main body, and the hopper cover and the butterfly valve are difficult to clean and dry comprehensively and effectively. The hopper cover and the butterfly valve can be attached with a large amount of material residues and dirt in the long-term use process, and if the hopper cover and the butterfly valve can not be thoroughly cleaned and dried, the hidden danger of bacterial breeding and material residue can be formed, and the pollution is caused to the storage and the transportation of the next material. In addition, due to the lack of advanced automated control and detection means, it is difficult for existing washers to ensure stability and consistency of the cleaning process. For example, in the process of taking and placing the cover, there is no position detection and vacuum degree detection device, the adsorption state of the hopper cover cannot be monitored in real time, and the hopper cover is easy to fall off in the process of taking and placing, so that equipment damage or safety accidents are caused. In the operation of the switch valve, no in-place detection device exists, and whether the valve is completely opened or closed cannot be accurately judged. In summary, the existing hopper cleaning machine has obvious defects in terms of automation degree, cleaning effect and operation safety. Along with the continuous expansion of industrial production scale and the increasing of product quality requirements, a novel hopper cleaning machine which can realize automatic feeding and discharging of a hopper into and from a cleaning chamber, automatic cover taking and closing and automatic valve opening and closing a
