Abstract

The utility model relates to a cooling panel turnover machine for base material of a prefinished floor, comprising a panel turnover machine. The cooling panel turnover machine for the base material of the prefinished floor is characterized by further comprising a tempering casing; the tempering casing is made of thermal insulation material and is internally provided with a heater; and an exhaust device is arranged above the tempering casing. In the utility model, by installing the tempering casing outside the panel turnover machine, the ambient temperature of the base material of the floor in the panel turnover machine can be better controlled, and the effects of effectively tempering panels, and stabilizing and improving the performance of the panels are achieved.

Description

Consolidated floor base material board cooler
Technical field
The utility model relates to a kind of board cooler, can reduce floor base material thickness swelling rate in winter effectively.
Background technology
The technological process of consolidated floor base material production generally is: section, and--------------fiber separation------------mating formation,------------cooling off modified,--------drying is put in storage in sanding in hot pressing in precompressed in applying glue by the check----that grades-packing in boiling in screening.Cool off and modifiedly realize by board cooler that mainly existing panel turnover machine generally opens in air, can't regulate modified ambient temperature and humidity, depend on extraneous environment to a great extent.
Because the winter environment temperature is lower, the sheet material rapid quenching of from press, coming out, the amplitude of cooling is excessive.The summer environment temperature is higher, and cooling range is less.Simultaneously modified humidity has very important influence to sheet material later stage performance stable.Unfavorable modified environment can reduce the curing performance of glue, and then influences plate property etc.Therefore under the same process condition, floor base material generally in the winter time thickness swelling rate apparently higher than summer.Usually adopt applying glue, the applying wax amount that improves sheet material, the method that reduces the continuous hot press speed of service to guarantee product quality in the prior art, overcome the higher problem of sheet material thickness swelling rate in winter, but the cost that increases applying glue, applying wax amount corresponding product can increase, and reduces the continuous press speed of service and can reduce output.
The utility model content
Technical problem to be solved in the utility model provides a kind of board cooler, can reduce winter floor base material thickness swelling rate.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of consolidated floor base material board cooler comprises panel turnover machine, it is characterized in that, also comprises the modified cover that is located at the panel turnover machine periphery.
Aforementioned consolidated floor base material board cooler is provided with heater in the modified cover, and the top of modified cover is provided with exhaust apparatus.Described modified cover is a heat-barrier material.
The utility model has following positive effect: the utility model is installed modified cover in the periphery of panel turnover machine, can control the ambient temperature of the floor base material that is positioned at panel turnover machine better, reaches effective modified sheet material, stablizes and improve the effect of plate property.Table 1 and table 2 are to be respectively the thickness swelling rate % of the different batches floor base material (the E1 level floor base material of 7.8mm) of prior art and the utility model acquisition.Table 3 is statistic analysis result of his-and-hers watches 1 and table 2.
Table 1 is the thickness swelling rate % of floor base material of the acquisition of prior art
Table 2 is the thickness swelling rate % of the floor base material of the utility model acquisition

Under same production technology, get the 7.8mm floor base material thickness swelling rate of transforming two batches of front and back respectively and make comparisons, transform preceding reduction, about 1% from showing the improved base material thickness swelling rate of apparent discovery.
Adopt two different variance what-ifs of sample such as following table to add up, batch A, P value=0.002<0.05 therefore in significance α=0.05 o'clock, is done two-sided test and will be refused null hypothesis, think transform after a batch A thickness swelling rate significantly reduce.Batch B in like manner, P value=0.0004<0.05 therefore in significance α=0.05 o'clock, is done two-sided test and will be refused null hypothesis, thinks that transforming a back batch B thickness swelling rate significantly reduces.
