Description
Technical field: the invention belongs to production equipment and the technology of building block, particularly a kind of foamed solidification stopping means and technology of sandwich PU building block production line.
Background technology: prior art document 1 Chinese patent application publication No. CN 102628303A discloses a kind of air entrained concrete sandwich polyurethane foam plastics building block continuous producing method, wherein " technical scheme that realizes the object of the invention is: a kind of air entrained concrete sandwich polyurethane foam plastics building block continuous producing method; the common process batch production concrete segment that manufactures a finished product is characterized in that also comprising following series-operation:
Line procedures in A, the building block: neatly lie against on the roller path the basic building block of finished product concrete and facial ornament building block in twos;
Operation is erect in B, building block upset: the above-mentioned finished product concrete segment that neatly lies against in twos on the roller path, overturn accordingly in twos 90 ° through switching mechanism, and become in twos and relative thirty years of age two line up the product concrete segment;
Spacing is adjusted operation between C, the two row's building blocks: a fixing wherein row is adopted in the spacing adjustment between the above-mentioned relative thirty years of age finished product concrete segment in twos, only adjust relative thirty years of age another and line up the position of product concrete segment, make it along moving perpendicular to the involutory in-plane of blockhouse through the spacing guiding mechanism, make in twos spacing between the relative thirty years of age finished product concrete segment adjust to the distance of technological requirement;
D, leakproof film place mat operation: when the opposed building block in twos of adjusting to technological requirement when spacing continues to run on the chain-plate type belt feeder forward, under unreeling machine cooperates, at chain-plate type belt feeder upper surface place mat plastic sheeting, this area mat plastic sheeting extends to foaming---curing area, and the other end of this area mat plastic sheeting draws rolling by winder then;
E, layering foamed process repeatedly: when the opposed building block in twos of adjusting to technological requirement when spacing continues to run to forward foaming district on the chain-plate type belt feeder, use quantitative pouring apparatus, between relative thirty years of age in twos building block, account for half the first time cast that the polyurethane foam raw material is cast total amount; After cast for the first time, carry out the cast second time, or repeatedly cast;
F, foaming layer curing process: cast finish after, adopt hot blast to solidify to the polyurethane foam layer, make in twos relative thirty years of age two to line up the product concrete segment and be combined into integral body through foaming layer;
G, be separated into the piece operation: use separator allow to be combined into whole two through foaming layer and line up the product concrete segment, be separated into by basic building block and facial ornament building block and between be compounded with the sandwich building block of monolithic of polyurethane foam layer;
H, sandwich building block down line process: adopt to count automatically and pile up bunching device, block-by-block rolls off the production line sandwich building block and piles up stacking behind counting.”
Though relate in the prior art document 1 " the foaming layer curing process: cast finish after, adopt hot blast to solidify to the polyurethane foam layer, make in twos relative thirty years of age two to line up the product concrete segment and be combined into integral body through foaming layer; Yet "; unexposed or relate in the foaming layer solidification process spacing to the basic building block, the top, the bonding side of non-foaming of faced block, the bottom that are erected between the location-plate; as to prevent from the foaming and intumescing process of polyurethane sandwich layer foamed material, occurring foamed solidification stopping means and the technology of displacement, to cause to be difficult to guarantee that the accurate dimension that reaches technological requirement is combined into sandwich PU building block.
Need to prove the life idea of pursuing green low-carbon along with people, the heat-insulating construction material of energy savings will substitute existing construction material, the building block of air entrained concrete sandwich polyurethane foam plastics also claims the building block of concrete sandwich hard polyurethane foam to arise at the historic moment.This is the building block that the sandwich polyurethane foam plastics constitutes between a kind of basic building block of finished product concrete of, rectangular shape identical or different by thickness and the facial ornament building block.Because the polyurethane foam plastics laminboard layer has good heat insulation effect, so this is a kind of novel building building block that will substitute existing building block.Its production method also rests on step making by hand the stage at present, prior art document 1 discloses a kind of air entrained concrete sandwich polyurethane foam plastics building block continuous producing method, but implement its method concrete sandwich hard polyurethane foam building block production line relevant device and technology still is not reported or open.This shows, study and design a kind of foamed solidification stopping means and technology of concrete sandwich hard polyurethane foam building block production line, the foamed solidification stopping means and the technology that are called for short sandwich PU building block production line are necessary.
PU is the abbreviation of polyurethanes Polyurethane, and Chinese polyurethanes by name is called for short polyurethane." PU " in the subject name of the present invention " foamed solidification stopping means and the technology of sandwich PU building block production line " refers in particular to polyurethane foam plastics, as shown in Figure 3, " sandwich PU building block " refer in particular to by isometric, wide, the uniform thickness on polyurethane hard bubble sandwiched 01 both sides or not the basic building block 02 of the rectangular shape of uniform thickness and facial ornament building block 03 through polyurethane foam high strength the air entrained concrete sandwich polyurethane foam plastics building block that is combined into.
