Problems solved by technology

[0003] The prior art, the patent No. 2011203905638, discloses a production equipment for double-sided embossing of PVB membranes. The technical solution is to realize double-sided cooling and printing of PVB membranes through the cooperation of preheating rolls and cooling rolls. , the main problem to be solved by this production equipment is that the production speed is slow and the efficiency is low, and the domestic output is difficult to meet the needs of the existing market
However, this technical solution has two defects: one is that the production equipment is preheated by the preheating roller first, and then passes through the embossing of the first anilox steel roller and the second anilox steel roller to form various patterns, PVB After the diaphragm is preheated, it will pass a certain distance to the anilox steel roller. During this distance, the temperature of the PVB diaphragm will drop, which is not enough to form a high-quality embossing pattern. After cooling, it will further complicate the process. , and the cooling step is superfluous on this equipment; the second is that in the process from the preheating roll to the anilox roll, because the transmission distance is too long, the PVB film cannot be kept in a tight state, and the PVB film will not be in a tight state all the time. There will be folds or overlapping states during the embossing process, which will lead to the success or failure of embossing
The problem with this embossing device is the synchronization and consistency of the upper embossing roll and the lower embossing roll. The friction between them, etc.), will lead to the reduction of embossing quality

Embodiment 1

[0032] Such as figure 1 Shown: a PVB film surface forming embossing equipment, including pre-forming device, embossing device and heating device.

[0033] The preforming device comprises a rotatable main photo roll 5 and a rotatable first photo roll 6 (secondary photo roll) in contact with (tangent to) said main photo roll 5 . The main light roll 5 and the first light roll 6 are on the same end face, and the end face is perpendicular to the horizontal plane.

[0034] The heating device includes a first heating device 4 and a second heating device 3 . The first heating device 4 is located at one side of the main light roll 5 , and the second heating device 3 is located at one side of the first embossing roll 2 . It should be noted that the first heating device 4 and the second heating device 3 are not located on the same side. The first heating device 4 and the second heating device 3 can be heating sheets made based on ordinary resistance wires, or segmented heating devices...

Embodiment 2

[0038] Such as figure 2 Shown: a PVB film surface forming embossing equipment, including pre-forming device, embossing device and heating device.

[0039] The preforming device includes a twelfth light roll 19, an eleventh light roll 18, a tenth light roll 17 and a master light roll which are tangent in sequence. Wherein, the main axes of the twelfth smooth roller 19 , the eleventh smooth roller 18 , the tenth smooth roller 17 and the main smooth roller 5 are located on the same horizontal plane. On the one hand, the role of the light roller is to preform the PVB film coming out of the extrusion die 8, and has a guiding effect, so that the PVB film is attached to the light roller and moves, shortening the distance of the PVB film outside.

[0040] The heating device includes a first heating device 4 and a second heating device 3 . The first heating device 4 is located at one side of the main light roll 5 , and the second heating device 3 is located at one side of the first ...

Embodiment 3

[0044] Such as image 3 Shown: a PVB film surface forming embossing equipment, including pre-forming device, embossing device and heating device.

[0045] The preforming device includes a ninth smooth roll 16 , an eighth smooth roll 15 , a seventh smooth roll 14 and a main smooth roll 5 tangentially in sequence. The axes of the ninth smooth roller 16 , the eighth smooth roller 15 , the seventh smooth roller 14 and the main smooth roller 5 are located at the same end face. The end surface has a certain angle with the horizontal plane.

[0046] The heating device includes a first heating device 4 and a second heating device 3 . The first heating device 4 is located at one side of the main light roll 5 , and the second heating device 3 is located at one side of the first embossing roll 2 . It should be noted that the first heating device 4 and the second heating device 3 are not located on the same side.

[0047] The embossing device includes a second embossing roller 1 and a...

Abstract

The invention discloses surface forming and knurling equipment for a PVB film and a production technology of the surface forming and knurling equipment. The surface forming and knurling equipment comprises a preforming device, a knurling device and heating devices. According to the surface forming and knurling equipment disclosed by the invention, a PVB film is formed into a uniform film piece through the preforming device, two surfaces of the PVB film piece are heated through the heating devices, and finally, the two surfaces of the PVB film piece are knurled through the knurling device so that a PVB knurling finished product is formed; and through the matching of the heating devices and the knurling device, the PVB film can be heated and knurled, so that the knurling quality and knurling effect are improved.

Description

technical field [0001] The invention relates to an embossing device and a production process thereof, in particular to a PVB film surface forming embossing device and a production process thereof, and belongs to the technical field of embossing devices. Background technique [0002] Polyvinyl butyral (PVB) film is an interlayer material used to make safety glass. Because of its good transparency and high impact strength, it is widely used in aviation and automobile fields. Specifically, safety glass is a special glass that adds a layer of polyvinyl butyral film with good weather resistance, sound insulation, and ultraviolet light insulation between two layers of ordinary glass. Safety glass can absorb impact energy when it is impacted by the outside world, so that the glass will not break and form a safety protection. [0003] The prior art, the patent No. 2011203905638, discloses a production equipment for double-sided embossing of PVB membranes. The technical solution is...
