Description

Technical Field

[0002] In smoke machine equipment, feeders are important conveying equipment, which are used to balance the material flow of the previous and next processes. Several rake nails are installed on the lifting belt of the feeder, which can effectively drive the material to rise and prevent the material from sliding down and blocking. During production, after the material goes through the rehumidification or feeding process, the material will absorb the liquid and moisture to enhance its adhesion. During transportation, some materials will adhere to the rake nails of the lifting belt of the feeder. Therefore, after each batch of production, the materials adhered to the rake nails need to be sprayed and cleaned in time to ensure the quality of the next batch of materials. However, due to the high position and large slope of the lifting belt, and the strong adhesion of the materials, the smoke stains on the surface of the rake nails cannot be completely removed by compressed air spraying. The rake nails can only be cleaned one by one manually, which not only increases the labor intensity, but also poses great safety hazards for the staff to climb high for cleaning operations, which seriously affects production efficiency.

[0040] Start the pneumatic motor 4. The pneumatic motor 4 can drive the active pulley 6 connected to its output end to rotate, and then drive the two driven pulleys 7 to rotate through the main belt teeth 8, so that the tension pulley 9 and the plurality of rotating pulleys 13 can be driven to rotate through the auxiliary belt teeth 10 meshing with the driven pulley 7. In the process of the driven pulley 7 and the plurality of rotating pulleys 13 rotating, the cleaning steel brush 12 connected to them through the rotating shaft also rotates accordingly.

At the same time, the air source is no longer introduced into the telescopic cylinder 2, and the telescopic end of the telescopic cylinder 2 retracts, driving the cleaning mechanism to move away from the feeder lifting belt, that is, to move back in the direction of the fixed bracket 1. The cleaning mechanism leaves the cleaning area so as not to affect the subsequent normal operation of the feeder lifting belt.
