First, the main structure and working principle of cement paste mixer:
1. Structure: It mainly consists of two-speed motor, transmission box, main shaft, eccentric seat, mixing blade, stirring pot, base, column, support, cover and program controller.
2. Working principle Two-speed motor (1) transmits power to the worm (3) in the transmission case (10) through the coupling (2) and then through the worm wheel (6) and a pair of gears (7) and (9) Give the spindle (8) and decelerate. The main shaft drives the eccentric seat (12) to rotate synchronously to revolve the stirring blade (16) fixed on the eccentric seat (12). At the same time, the agitating blade completes the rotation motion around the fixed internal gear (11) through the planetary gear (13) at the upper end of the agitating blade shaft (14). The two-speed motor automatically completes a slow-stop-fast-forward working procedure through time-controlled controller control. The stirring pot (17) and the sliding plate (18) are rotationally locked by the eccentric grooves.
The cement paste mixer installation only needs to place the main unit on a flat cement platform, and a 5~8mm thick rubber plate is placed on the bottom surface. Power and safety ground The machine is shipped with a 2m long power supply and a four-pin socket. It must be ensured that the phase and neutral lines are correct for power. The electrical insulation has been up to standard at the factory. In order to ensure the safety of electricity, please securely ground the fuselage safety grounding mark with a multi-strand plastic copper core wire of not less than 1mm2 cross section.
2. Operation and use of cement paste mixer The handle (20) can be used to drive the slide (18) to move the stirrer up and down along the guide rail of the column (21). After moving up into position, tighten the set screw (19) to stir, and remove the stirring pot instead. Look from the top down to see the direction of rotation of the blade clockwise. The direction of revolution is reversed.
First place the three switches (1K, 2K) in the stop position, then plug the time controller plug into the “programmed input†socket of the panel before turning on the power.
Third, the electrical operation is divided into manual and automatic
1. Auto: Turn the switch 1K to the automatic position, that is, automatically complete the slow stirring for 120 seconds, the alarm for 5 seconds after stopping for 10 seconds, and the quick stirring for 120 seconds, then stop automatically. When the automatic program ends, if the 1K switch is placed in the stop, and then the 1K switch is placed in the automatic, the next automatic program is started. After each automatic program is finished, the 1K switch must be placed in the stop to prevent the program controller from malfunctioning after the power failure.
2. Manual: Turn the switch 1K to the manual position, and then place the three-position switch 2K in the slow, stop, fast, and stop positions, then complete each action separately and manually time.
Note: The three-phase power supply wiring of the socket must ensure that the direction of the blade revolution is the same as the direction marked on the body, otherwise the stirring mechanism will be easily damaged.
Fourth, cement paste mixer adjustment and maintenance
1. Adjustment: The machine has adjusted the gap between the stirring blade and the stirring pot to 2±1mm.
The working gap of the stirring blade and the stirring pot is adjusted, and the adjusting nut (15) can be loosened to rotate the stirring blade to move up and down, and then the detecting rod is used to detect the correct gap, and then the adjusting nut (15) can be tightened. Or loosen the screws connecting the motor and the column (21), the flange of the reduction box (10) and the motor (1), and then tighten the screws.
2, maintenance:
(1) The work site should be kept clean. After each use, the mixing mortar and the residual mortar inside and outside the mixing pot should be thoroughly removed, and the mortar and dirt on the scattered and splashing machine should be cleaned. After drying, put on the shield. Prevent dust.
(2) This unit has no external oil filler holes. In the transmission case, the moving parts such as the worm gear, the gear and the bearing are added with molybdenum disulfide grease once a quarter. When refueling, the bearing cap can be opened separately, and between the support and the column guide rail, the lubricating mechanism should be dripped frequently between the lifting mechanisms. Maintenance once a year, all the machine is cleaned and greased and greased.
