Embodiment
Below in conjunction with the accompanying drawings, clear complete description is carried out to the technical scheme in the utility model embodiment.
The effect of stack cooling jacket mainly is to participate in heat exchange, regulation calendering roll surface temperature and calendering roller surface temperature
The uniformity of degree.After stack linear velocity is improved, stack heat exchange accelerates, and cooling current have to the change for rolling roll temperature
Changed, along with the otherness of supplied materials temperature section temperature, calendering roller surface transverse temperature difference can be aggravated greatly, product thickness is caused
It is uneven, brought inconvenience to deep processing.
Refer to Fig. 1, the utility model discloses it is a kind of be used for that photovoltaic pattern glass under 200 tons of extraction to produce it is new
Stack, including roll body 1 and cooling water core 2, roll body 1 are hollow structure, and inside sets cooling water core 2, is set at the two ends of roll body 1
There is fixed cover 3, fixed cover 3 is connected by bolt with roll body 1, roll body 1 and cooling water core 2 are fixed.
Fig. 2, Fig. 3 and Fig. 4 are referred to, above-mentioned cooling water core 2 includes water inlet pipe 21, water-stop sheet 22 and support 23, water-stop sheet
22 and support 23 water inlet pipe 21 is supported on inside roll body 1.Water inlet pipe 21 is intake by two ends, and apopore is drilled with water inlet pipe 21
24, according to transverse temperature difference, gradient design is carried out to the aperture of apopore 24 successively, and take out-of-stream method to cool down.It is above-mentioned every
Provided with axis hole, surrounding in annular in the middle of water plate 22, the cooling water that 22 pairs of water-stop sheet enters stack cavity carries out a point chamber, typically
It is divided into four chambers, it is ensured that cooling water is uniformly cooled down to calendering roller wall, four groups of apopores is opened up on water-stop sheet 22, respectively with four chambers
Body correspondence.Axis hole is provided with the middle of above-mentioned support 23, four support bars are surrounded by.
Step type opens up apopore 24 on water inlet pipe 21, and the aperture of apopore 24 is incomplete same, apopore 24
Aperture determines according to the temperature of stack acquisition surface, through calculating each apopore 24 the distance between and aperture it is big
It is small.Refer to Fig. 5, ring water inlet pipe 21 is distributed 4 groups of apopores 24, every group of apopore includes 8 water outlets 24, it is respectively labeled as I ~
VIII, each apopore is symmetrical along the center line of water inlet pipe 21, and the spacing between apopore I ~ IV is respectively 200mm, and its aperture is successively
