Problems solved by technology

[0003] During the processing and preparation of polyurethane caulking agents, raw material filling, gas filling and shaking and mixing are generally processed. Among them, in the process of raw material filling, most of the existing filling equipment is semi-automatic filling equipment. Filling needs manual cooperation with filling equipment to complete the filling, the degree of automation is low, additional manual assistance is required, the labor cost is high, and the filling efficiency is low

Abstract

The present invention relates to a preparation method of polyurethane caulking agent, in particular to a raw material filling equipment for polyurethane caulking agent, comprising a workbench, a tank conveying device, a rotary transposition workbench, a clamping and positioning mechanism and a raw material filling mechanism , the equipment provided by the present invention can be applicable to the automatic preparation process of polyurethane caulking agent, and is specifically suitable for the automatic filling of polyurethane raw materials. The traditional semi-automatic processing mode is replaced by the automatic filling process, which greatly improves the The efficiency of preparation and processing reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of polyurethane material processing, and specifically proposes a preparation method of a polyurethane caulking agent. Background technique [0002] Polyurethane caulk is the product of the cross combination of aerosol technology and polyurethane foam technology. It is a kind of polyurethane, which can be used for sealing and plugging, filling gaps, fixing and bonding, heat preservation and sound insulation, especially for sealing and waterproofing between plastic steel or aluminum alloy doors, windows and walls. [0003] During the processing and preparation of polyurethane caulking agents, raw material filling, gas filling and shaking and mixing are generally processed. Among them, in the process of raw material filling, most of the existing filling equipment is semi-automatic filling equipment. Filling needs manual cooperation with filling equipment to complete the filling, the degree of automation is low...
