Description

Technical Field

[0001] The utility model relates to the technical field of open mills, in particular to an open mill with a cleaning structure. Background Technique

[0002] An open rubber mill has two horizontally arranged rollers. It is a machine for rubber mixing between the two rollers, abbreviated as an open mill. The material is pulled into the roller gap under the action of friction at different linear speeds between the two oppositely rotating rollers. The material passing through the roller gap is strongly sheared and extruded, causing the temperature of the material to rise and the plasticity to increase, so as to achieve the purpose of rubber mixing, and is used for operations such as plasticizing, mixing, sheet pressing and hot refining.

[0003] After the open mill is used, it needs to be cleaned and maintained. Usually, the operator uses items such as a scraper and a towel to clean the material adhered to the outside of the roller. Because it needs to be shut down for cleaning, the operator needs to manually turn the roller to clean it thoroughly. This work is relatively complicated. If cleaning is carried out while the machine is running, the operator will be at risk of injury. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an open mill with a cleaning structure. By setting the external structure, the utility model enables the operator to complete the cleaning without touching the open mill when the open mill is running, and the cleaning and maintenance are carried out simultaneously, which can not only ensure the personal safety of the operator, but also complete the maintenance work of the open mill.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Two baffles 10 are installed on the inner wall surface of the internal mixer body 1 through bolts, and a telescopic support foot 12 is installed on the lower wall surface of the internal mixer body 1. The elastic support structure can support and limit the cleaning plate structure and the maintenance structure. When the cleaning plate structure and the maintenance structure are not in use, the elastic support structure can prevent them from delaying the normal operation of the internal mixer body 1. At the same time, when the cleaning plate structure and the maintenance structure are needed, the elastic support structure can also enable them to quickly participate in the work.

[0026] Specifically, the cleaning plate structure includes: a cleaning bottom plate 6 and two scraping plates 7; The cleaning bottom plate 6 is installed between the two limit plates 2, the two scraping plates 7 are respectively installed on the lower wall surface of the cleaning bottom plate 6, a pulling handle 11 is installed on the upper wall surface of the cleaning bottom plate 6, and the cleaning plate structure can clean the rollers of the internal mixer body 1 and can scrape off the materials adhering to the outer part of the rollers of the internal mixer body 1 to ensure the cleanliness of the rollers of the internal mixer body 1.

[0027] Specifically, the maintenance structure includes: a maintenance base 8 and a maintenance cotton head 9; The maintenance base 8 is installed on the lower wall surface of the cleaning bottom plate 6, and the maintenance cotton head 9 is installed on the lower wall surface of the maintenance base 8.

[0028] Working principle: When using the present utility model, the operator connects an external AC power supply to the present utility model to provide energy for the electrical appliances in the present utility model. After the operator finishes using the internal mixer body 1, the internal mixer body 1 can be adjusted to the lowest speed. Then, the operator directly applies the maintenance isolation oil to the outside of the maintenance cotton head 9, so that the inside of the maintenance cotton head 9 soaks into the maintenance isolation oil. Then, the operator pulls down the pulling handle 11. At this time, the two support plates 5 and the cleaning bottom plate 6 will move downward under the action of the pulling force. At this time, the two sliding rods 3 slide downward inside the two limiting plates 2, and the spring 4 contracts until the maintenance cotton head 9 and the two scraping plates 7 respectively contact the rollers of the internal mixer body 1. At this time, the two rollers of the internal mixer body 1 rotating at the lowest speed will respectively rub against the two scraping plates 7, and the materials remaining on the outside of the rollers of the internal mixer body 1 can be scraped off. Moreover, the maintenance cotton head 9 also contacts the two rollers of the internal mixer body 1, and can respectively contaminate the two rollers with the maintenance isolation oil for the maintenance of the two rollers. When the cleaning is completed, the operator releases the pulling handle 11, and the spring 4 resets and the sliding rod 3 slides upward inside the two limiting plates 2 until the two support plates 5 and the cleaning bottom plate 6 return to their original positions. Among them, the baffle 10 can prevent the overflow of materials, and the telescopic support feet 12 can adjust the height of the internal mixer body 1 to prevent the formation of the sliding rod 3 from being insufficient.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
