Description

Technical Field

[0001] The utility model relates to the field of unloading devices, in particular to an automatic unloading device for a tunnel kiln. Background Art

[0002] In the current daily-use ceramic tunnel kiln firing production, the fired products must be unloaded one by one from the pottery bodies piled on the kiln cart coming out of the tunnel kiln. Workers frequently come in and out and repeat the work frequently, which has high labor intensity and low efficiency. In addition, although the products are cooled after coming out of the tunnel kiln, the temperature of the working environment is still 50-60 degrees Celsius when the workers unload them, and the temperature of the working environment is high.

[0003] Chinese patent publication number CN104154744B discloses an automatic unloading device for a tunnel kiln. In the initial working state, the up-down moving plate is at the uppermost position. The worker first pushes the kiln frame to the A station, and the air claw grabs the pallet and pushes the pallet to one side of the kiln frame. The telescopic cylinder drives the suction cup mounting plate to move downward, and the suction cup sucks the bowl blank placed in the bowl body. The piston rod of the telescopic cylinder is retracted to move the bowl blank out of the bowl body, and with the cooperation of the moving cylinder, the bowl blank is sent to the conveyor belt to the next process, thereby completing the work of removing the bowl blank, and then the grabbing cylinder is retracted to put the pallet on the kiln frame, and the up-down moving plate is shifted downward to the height of the next pallet, and the working process is repeated. This device solves the problems of high labor intensity, poor working environment, and low degree of automation of traditional equipment, and has the advantages of simple operation and reduced work errors.

[0004] However, in the above technical solution, the pallet needs to be pushed out from the kiln rack before the bowl embryos on the pallet can be placed on the conveyor belt, which causes the bowl embryos to shake easily when the pallet moves, affecting the subsequent picking and unloading.
