A distributing boom assembly used in a continuous production line of polyurethane insulation boards

Abstract

The invention discloses a material distribution boom assembly used for a polyurethane insulation board continuous production line. A first level T-shaped flow distributor, second level T-shaped flow distributors and third level T-shaped flow distributors are connected together through hollow double-end bolts to form the material distribution boom assembly with a three-level flow distribution system. Materials enter from an inlet of the first level T-shaped flow distributor and are divided into two parts; the two parts of the materials flow leftwards and rightwards to enter the two second level T-shaped flow distributors respectively; each of the two parts of the materials is divided into two parts after the distribution of the second level T-shaped flow distributors; the four parts of the materials enter the four third level T-shaped flow distributors respectively; the materials flow out from material nozzles of eight outlets respectively after the distribution of the third level T-shaped flow distributors again and are evenly poured on a material distribution platform. In this way, the material distribution process is stable, and the stability of products is guaranteed. Intervals between the outlet positions can be adjusted through rotation angles in the material nozzle outlet positions, so that hollow protuberances, creases and other phenomena are avoided in the production process. An on-line adjustment can be achieved in the adjustment process, so that the material waste is avoided. Meanwhile, all parts of the T-shaped flow distributors are detachable, easy to clean and convenient to assemble, so that the problem that a polyurethane material distribution system is difficult to clean is solved.

Description

technical field [0001] The invention relates to a distributing device of a production line, in particular to a distributing rod assembly used in a continuous production line of polyurethane boards. Background technique [0002] Polyurethane materials are widely used in building insulation, central air conditioning, insulation boxes, chemical tanks and other fields due to their excellent fireproof, flame retardant, moisture-proof, high-temperature resistance and other properties. In particular, its performance of taking into account heat preservation, fire prevention and construction has attracted widespread attention, and has been widely promoted as the best building heat preservation material. [0003] The traditional continuous line production method of polyurethane insulation board adopts an integral distribution boom, that is, a number of small holes are punched on a straight pipe to distribute materials, and at the same time, continuous distribution is realized by using...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing integral distribution boom leads to uneven cloth distribution, if hollowing, creases and other phenomena occur, the state of the distribution boom cannot be adjusted online, and because the polyurethane raw material is easy to foam and form a solid, therefore If the material remaining in the boom is not cleaned in time, it will easily block the distribution channel. At the same time, because the reacted polyurethane raw material is extremely difficult to clean, the cleaning of the traditional integral boom is very troublesome, and it is easy to have residue, which will affect the One-time use, high cost, and labor-intensive cleaning
