A screw conveyor sealing device

Abstract

The invention discloses a spiral conveyer sealing device. The spiral conveyer sealing device is characterized in that a bearing base is fixed in a hole at the right end of a spiral groove body; the left end of the bearing base is a step-shaped structure; a first step surface is contacted with a right end surface of the spiral groove body; a large O-shaped sealing ring is fixed in a groove in the first step surface of the bearing base; a lip-shaped sealing ring and a bearing are mounted in the bearing base; the lip-shaped sealing ring is near a spiral rod end; an elastic retainer ring for hole is mounted in the bearing base; a connecting shaft penetrates through the bearing base and the bearing, one end thereof is connected with a spiral rod, and the other end is connected with a motor, so that the spiral rod and the motor are connected as a whole through the connecting shaft; the connecting shaft is fixed in the bearing base through a contact part at the left end of the bearing base and an elastic retainer ring for shaft at the right end of the bearing base; and a small O-shaped sealing ring is fixed in a groove formed in the contact surface, corresponding to the contact part of the bearing base, of the connecting shaft. The spiral conveyer sealing device has the beneficial effects of solving the problem of outward flowing of cutting liquid in the use process, improving the reliability of the sealing device and prolonging the service life of the sealing device.

Description

technical field [0001] The invention belongs to the field of machine tool processing, and relates to a chip conveying device containing a large amount of cutting fluid, in particular to a screw conveyor sealing device. Background technique [0002] In the field of machine tool processing, cutting and grinding of metal materials generally use cutting fluid to cool, lubricate, and clean tools and workpieces. Chips generated during processing are mixed with cutting fluid inside the machine tool. Chip conveying devices are used together with cutting fluid, The chips are conveyed together outside the machine for disposal. Due to the limited space inside the machine tool, screw conveyors are usually used to transport the mixture of the two to the next level of conveying device or chip collector. During the conveying process, the rotating shaft is immersed in the cutting fluid. Due to the action of chips, there is no fixed device at the front end of the screw rod to swing. , When ...
