Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire production, specifically a high-temperature warehouse double-layer access control automatic control system for the transportation of natural rubber blocks during high-temperature heating in and out of the warehouse. Background Technology
[0002] As is well known, before processing in an internal mixer, natural raw rubber is formed into blocks for convenient transportation and storage. Due to factors such as winter and regional variations, the temperature of the rubber compound can be too low, especially the core portion inside the block. When directly using an internal mixer for mixing, the mixing process cannot achieve a uniform mixing effect, and the low-temperature raw rubber cannot be used, affecting the quality of the compounded rubber. Currently, the main method for dealing with low-temperature raw rubber is to heat the compound. Heated storage silos are a quick and temperature-uniform method. However, during the process of rubber entering and leaving the silo, the opening and closing of the silo door causes heat to escape from the heated silo, while cold air from outside enters, resulting in temperature imbalance inside the heated silo, with localized high temperatures and low temperatures near the silo door. This fails to achieve the goal of uniform heating, and prolonged door opening also results in significant heat energy loss and waste, increasing energy costs. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a double-layer access control system for high-temperature warehouses, which eliminates the heat loss of natural rubber blocks during the opening process when the doors are opened during the high-temperature heating and transportation of the natural rubber blocks in and out of the warehouse.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a double-layer access control system for a high-temperature warehouse, comprising a heating warehouse, characterized in that the heating warehouse has an outdoor door and an indoor door, with a closed corridor connecting the outdoor and indoor doors; a rubber material conveying platform runs through the outdoor door, the indoor door, and the closed corridor; conveying rollers are installed on the rubber material conveying platform; and an outdoor waiting station for raw rubber material is located on the rubber material conveying platform outside the outdoor door, with an outdoor waiting station sensor photoelectric sensor installed at the outdoor waiting station. The outdoor and indoor doors of the heating warehouse are controlled to open by an outdoor door drive motor and an indoor door drive motor, respectively. The enclosed corridor inside the outdoor door of the heating warehouse has a waiting station for adhesive materials entering the corridor, which is equipped with a waiting station photoelectric sensor. The enclosed corridor inside the indoor door of the heating warehouse has an indoor door adhesive material waiting station, which is equipped with an indoor door waiting area confirmation photoelectric sensor. The heating warehouse outside the indoor door of the heating warehouse has an adhesive material entering the heating warehouse waiting station, which is equipped with an indoor waiting area photoelectric sensor.
[0005] The beneficial effect of this utility model is that it eliminates the risk of mixing quality caused by prolonged opening of the door during the process of rubber material entering the warehouse and by uneven heating in some areas of the heated warehouse. Attached Figure Description

[0009] In the figure, this utility model includes a heating warehouse, which has an outdoor door 5 and an indoor door 14. The outdoor door 5 and the indoor door 14 are installed in corresponding doorways 8. A closed corridor 9 connects the outdoor door 5 and the indoor door 14. A rubber material conveying platform 2 passes through the outdoor door 5, the indoor door 14, and the closed corridor 9. Conveying rollers 3 are installed on the rubber material conveying platform 2. An outdoor waiting station 1 for raw rubber material is set on the rubber material conveying platform 2 outside the outdoor door 5. An outdoor waiting station photoelectric sensor 4 is installed on the outdoor waiting station 1. The outdoor door 5 and the indoor door 14 are respectively connected by a doorway 8. The outer door drive motor 6 and the inner door drive motor 12 are controlled to open via the outer door traction pulley 7 and the inner door traction pulley 13. The enclosed corridor 9 inside the outer door 5 of the heating warehouse is equipped with a waiting station 10 for adhesive entry, and a waiting station photoelectric sensor 11 is installed on the adhesive entry corridor waiting station 10. The enclosed corridor 9 inside the inner door 14 of the heating warehouse is equipped with an inner door adhesive waiting station 15, and an inner door waiting area confirmation photoelectric sensor 16 is installed on the inner door adhesive waiting station 15. The heating warehouse outside the inner door 14 of the heating warehouse is equipped with an adhesive entry heating warehouse waiting station 17, and an inner heating warehouse waiting area photoelectric sensor 18 is installed on the adhesive entry heating warehouse waiting station 17.
[0010] The rubber material conveying platform 2 transports the raw rubber material to the outdoor waiting station 1 through the rotation of the conveying rollers 3. The outdoor waiting station photoelectric sensor 4 senses and confirms the position of the rubber material. At the same time, the waiting station photoelectric sensor 11 confirms that there is no rubber material in the waiting station of the enclosed corridor 9. When there is no rubber material in the waiting station, the outdoor door drive motor 6 is energized and drives the outdoor door 5 of the heating warehouse to rise and open through the outdoor door traction pulley 7. After opening, the rubber material enters the enclosed corridor 9 through the door opening 8. When the rubber material enters the waiting station 10 of the corridor, the outdoor door drive motor 6 reverses and runs after the position is confirmed by the waiting area photoelectric sensor 11, and the outdoor door 5 of the heating warehouse closes. After closing, the rubber material continues to be conveyed. When it is conveyed to the rubber material waiting station 15 inside the door, the position is confirmed by the photoelectric sensor 16 in the waiting area of the inside door. The indoor door drive motor 12 is energized and drives the indoor door 14 of the heating chamber to open through the rotation of the indoor door traction pulley 13. After the indoor door 14 of the heating chamber is opened to the correct position, the rubber material continues to be conveyed to the rubber material entering the heating chamber waiting station 17. The position is confirmed by the photoelectric sensor 18 in the waiting area of the heating chamber. The indoor door drive motor 12 is energized and reverses to lower the indoor door 14 of the heating chamber, completing the closed-loop conveying of the rubber material into the chamber.
