Production equipment for polyurethane raw material used for manufacturing soft volleyballs

Abstract

The invention relates to the technical field of polyurethane raw material production, and discloses production equipment for a polyurethane raw material used for manufacturing soft volleyballs. The equipment comprises a shell, wherein the bottom of the shell is movably connected with a support frame, the top of the shell is fixedly connected with a motor box, the top of the shell is fixedly connected with an air inlet, a gas pressure meter is fixedly connected to the top of the shell, and a connecting block is fixedly connected to the outer side of the motor box. When the production equipment for the polyurethane raw material used for manufacturing the soft volleyballs works, through an arranged triggering mechanism and an extruding mechanism arranged in a matched mode, the triggering mechanism senses eccentric motion of an output shaft in the using process of the equipment, an internal circuit is switched on, so the extruding mechanism evenly achieves Ampere force to limit the output shaft; and therefore, when a gap between a shaft sleeve and a bearing is too large due to excessive abrasion of the bearing, eccentric rotation of the output shaft is avoided, damage to a reaction kettle during work is prevented, noise generated during work of the reaction kettle is reduced, and the service life of the reaction kettle is prolonged.

Description

technical field [0001] The invention belongs to the technical field of polyurethane raw material production, in particular to polyurethane raw material production equipment for making soft volleyballs. Background technique [0002] The full name of polyurethane is polyurethane, which is a polymer compound. Soft polyurethane mainly has a thermoplastic linear structure. It has better stability, chemical resistance, and resilience than PV polyurethane raw materials for foaming materials. And mechanical properties, with smaller compression set. It has good heat insulation, sound insulation, shock resistance and anti-virus performance, and is usually prepared in a reaction kettle in industrial production. [0003] However, during the long-term use of polyurethane reactors currently on the market, due to the aging of the drive device, excessive wear of the bearing will occur, resulting in an excessive gap between the shaft sleeve and the bearing, resulting in eccentric rotation o...
