Description

Technical Field

[0001] The present application relates to the technical field of sheet forming equipment, and in particular to a grinding device for a steel belt of a sheet forming machine. Background Art

[0002] The sheet forming process generally includes the sheet line drying area, the sheet line slurry area and the sheet line forming area. The process task of the sheet line drying area is to evenly mix the ash and tobacco stems that meet the incoming material requirements in a certain proportion, and after heating and grinding, they become ash that meets the process requirements for use in the next process; the process task of the sheet line slurry area is to prepare viscose as required, heat the prepared viscose and fully mix it with dry ash in a certain proportion to form a thick slurry that meets the process requirements, and then transport it to the next process; the process task of the sheet line forming area is: in the sheet forming system, the thick ash slurry is evenly and continuously coated on the jointless sheet forming steel belt, dried and then removed from the sheet forming steel belt, and then transported to the sheet slicer for processing, and then transported to the bagging machine.

[0003] The structure of the sheet forming system is mainly composed of a frame, active rollers, driven rollers, steel belts, steel belt heating system, hot air system, exhaust system, hot water system, feeding system, anti-adhesive system, etc. The principle of sheet drying is: the sheet is dried by the principle of heat transfer and convection. The thick slurry is cast on the running steel belt and enters the baking oven. There are many steam nozzles in the steam box under the steel belt to spray steam directly on the lower surface of the steel belt to evenly heat the steel belt, and bake the material by heat transfer. Dry hot air is blown into the dry end of the baking oven and is sucked away from the wet end by the exhaust fan in the opposite direction of the material running. The hot air dries the material by convection and takes away the moisture of the material. The thick slurry continuously undergoes three processes in the baking oven about 30 meters long: heat absorption, balance, and dehydration until it becomes a sheet with qualified moisture.

[0004] From the above, it can be seen that the steel belt is used frequently in the thin film forming process, and it is inevitable that it will be damaged. The damaged area of ​​the steel belt is often distributed linearly along the movement direction of the steel belt. The damage to the steel belt seriously affects the quality of the thin film. This requires maintenance workers to use gauze to grind the damaged line of the steel belt, which results in high labor workload, unstable grinding quality and low work efficiency.
