[0002] At present, the ring mode briquetting machine generally adopts a fixed die-roll gap, and the die-roll gap cannot be adjusted in real time according to the actual working conditions to maintain the stability of the forming pressure, resulting in uneven forming quality of straw briquettes; when it is necessary to adjust When the gap between the die rollers is reached, it must be disassembled and adjusted after the shutdown
Every time the gap between the ring die and the pressure roller is adjusted, the upper platen needs to be disassembled, and multiple lock nuts must be adjusted at the same time. The adjustment process is complicated. The process usually takes at least 2 to 3 hours, which is very time-consuming and labor-intensive, which seriously affects the work. efficiency
At the same time, the adjustment of the gap puts forward high requirements on the skills of the operators. Once the adjustment is not done properly, it will seriously affect the working performance of the ring die forming machine.

Abstract
The invention provides a mold roller gap stepless automatic regulation device of a vertical annular mold straw briquetting machine. The mold roller gap stepless automatic regulation device comprises an upper press plate, a grinding disc, an eccentric shaft A, an eccentric shaft B, a vertical main shaft, a PLC (programmable logic controller), an intermediate relay, an electromagnetic valve, a miniature hydraulic pump, an oil tank, a branch oil pipe A, a branch oil pipe B, a push rod and a tray. Strain force sensors sense strain of the eccentric shaft A and the eccentric shaft B in real time and transmit information to the PLC, the PLC controls the electromagnetic valve and the intermediate relay to work, further, the extension and retraction of the push rod are controlled through oil pressure, a mold roller gap is automatically regulated in a stepless way, the effective regulation on the mold roller gap is realized, the stability of forming extrusion force among grinding rollers is ensured, in addition, the briquette forming quality and the briquette forming uniformity are improved, meanwhile, the excessive abrasion among mold rollers is also reduced, the service life of each mold roller is prolonged, and the energy consumption during the production is also reduced.
Description
technical field [0001] The invention relates to a gap adjustment device, in particular to a stepless automatic adjustment device for the die roller gap of a vertical ring die straw briquetting machine. technical background [0002] At present, the ring mode briquetting machine generally adopts a fixed die-roll gap, and the die-roll gap cannot be adjusted in real time according to the actual working conditions to maintain the stability of the forming pressure, resulting in uneven forming quality of straw briquettes; when it is necessary to adjust When the gap between the mold rolls is changed, it must be disassembled and adjusted after the machine is shut down. Every time the gap between the ring die and the pressure roller is adjusted, the upper platen needs to be disassembled, and multiple lock nuts must be adjusted at the same time. The adjustment process is complicated. The process usually takes at least 2 to 3 hours, which is very time-consuming and labor-intensive, whic...
