Analyze the working condition of snail pressing by automatic oil press

Before starting the automatic oil press, all auxiliary appliances and containers should be prepared, and the elasticity of the transmission belt should be checked and adjusted. Then turn on the motor, let the machine run idly for about 15 minutes, and check the speed of the screw shaft juice pouch filling machine. The normal speed should be around 33dmin. When idling, pay attention to the meshing condition of the gears in the gearbox and whether the sound is normal, whether the bearing parts and the motor are normal. When the oil press is idling, the motor current should be about 3A. If the current is too high, stop and check immediately, and restart after adjustment. The oil press is a machine that continuously advances the blank in the press chamber and extracts crude oil under the action of dynamic extrusion. In addition to the feeding hopper, the press chamber is the main part of the work. It consists of a screw shaft and a cylindrical press cage. There are two ways of single-stage pressing and double-stage pressing. The single-stage only needs one horizontal pressing chamber mango pulp maker machine, and the two-stage has another Add a straight press chamber to stop the first press. The squeezing screw shaft is composed of a plurality of squeezing screws and pitch rings sleeved on the shaft.

Each screw has a certain pitch and depth, and the pitch of each screw on a shaft is gradually shortened from the inlet to the outlet, and the screw depth gradually becomes shallower, so that the volume of the press chamber is gradually changed from the inlet to the outlet. Decrease, after the billet enters the press chamber, it advances along the snail stage to the exit, and the pressure it receives gradually increases, thereby gradually squeezing out the oil. A gasket is installed between the sliver and the sliver of the cylindrical pressing cage of the screw press to form an oil outlet gap, and the extruded crude oil flows out through the gap electric sugarcane juicer machine. Don’t feed the material too fast at the beginning of the press, otherwise the pressure in the press chamber will suddenly increase, and the press screw shaft will not rotate, forming a press chamber blockage, and even breaking the press cage, causing a serious accident. Therefore, when the contraction begins, the feed should be slowly put into the feed hopper to stop the oil press from running in. Repeat this repeatedly for more than 3 to 4 hours, so that the temperature of the oil press gradually rises, so that the temperature of the press chamber is low when the green smoke begins to press. It can be turned slowly. The handle on the stud can increase the thickness of the cake. At the same time, the moisture of the pressed embryo material will be increased, and the temperature of the pressing chamber will be reached. When the temperature rises to about 90°C, after the oil press works normally, the oil press can adjust the cake thickness to 1.5~2.5mm, and tighten the fastening nut.
