Main structure and working principle of rubber sand mixer


Main structure and working principle 1. Structure: It mainly consists of two-speed motor, sanding box, transmission box, main shaft, eccentric seat, mixing blade, stirring pot, base, main column, support, and program controller. 2. Working principle The two-speed motor transmits the power to the worm in the transmission case through the connecting sleeve, and then transmits it to the main shaft through the worm wheel and a pair of gears and decelerates. The main shaft drives the eccentric seat to rotate synchronously, so that the stirring blade fixed on the eccentric seat revolves. At the same time, the stirring blade completes the rotation motion around the fixed ring gear through the planetary gears at the upper end of the blade shaft. The mixing pot and the support are rotated and locked by the eccentric groove. After adding sand, the sand can be automatically sanded or manually sanded at the specified time, and the handle is used for lifting and positioning the stirring pot position.

Lifting and installation 1. Lifting, the machine does not have a lifting device, and can be manually transported. 2. The machine is installed, just put the host on a flat cement platform, and put a layer of 5-8MM rubber plate on the bottom.

Operation and use will be the power socket of the machine, the red knowledge light is on, indicating that the power is turned on, then plug the program controller plug into the local program controller socket, the digital display of the program controller is zero, and the sand tank is filled with 1350 g standard sand, stirring pot The inside is filled with 225 grams of water and 450 grams of cement. The stirring pot is placed in the positioning hole of the support, the pot is turned clockwise until it is locked, and then the handle is moved to make the stirring pot move in the stirring working position. Electrical operation is divided into manual and automatic. 1. Automatic: Turn the toggle switch 1K to the automatic position, press the programmable controller start button, that is, automatically complete a low speed of 30 seconds - then low speed for 30 seconds, while automatic sanding end - high speed 30 Second - stop 90 seconds - high speed 60 seconds - stop working program. The whole process is 240 seconds ± 1 second, then move the handle to move the stirring pot downward, turn the stirring pot counterclockwise to the release position, and remove the stirring pot. 2. Manual: Turn the toggle switch to the manual position, the machine will rotate. According to the test requirements, the low speed and high speed rotation time can be arbitrarily controlled, and the sanding time can be controlled arbitrarily, early, late, long and short. The button switch 2K controls the low speed and high speed, and the button switch 3K controls the sanding and stopping.

Adjustment and maintenance 1. Adjustment: The working gap between the stirring blade and the stirring pot has been adjusted to the range of 3±1mm before leaving the factory. The adjustment of the working gap between the stirring blade and the stirring pot can be released by rotating the adjusting blade to move the upper and lower parts to the correct clearance, and then tightening the adjusting nut. 2. Maintenance: (1) The work site should be kept clean. After each use, thoroughly remove the residual mortar inside and outside the mixing bowl and the mixing pot, and clean the mortar and dirt scattered and splashed on the machine. After drying, Put on the shield to prevent dust. (2) There is no external oil filler hole in this unit. In the transmission box, the worm gears, gears and bearings and other moving parts are added with butter once a quarter. In addition, sometimes the gearbox cover can be opened. Between the support and the column guide rails, the lifting mechanism should be dripped with oil lubrication every year. Once, clean the unit and fill with grease and grease. (3) If there is metal impact noise when the machine is running, first check whether the gap between the stirring blade and the stirring pot is normal. (4) When using the stirring pot, it should be handled gently and not randomly, so as not to cause deformation of the stirring pot. (5) The electrical insulation should be checked frequently, at a temperature of 20 ° C ± 5 ° C relative temperature 50% - 70% of the cold insulation resistance 7 / 5 Ω.
