The following describes various embodiments of the present invention in detail in conjunction with the drawings.

[0038] Example 1

[0039] See also Figures 1 to 12The present invention preferably provides a technical solution: a PVB film forming mold, comprising: a slide 1, an extruder 5 assembled with the slide 1; an elevator assembly 611 arranged on the slide 1; and a double-roller cooling assembly arranged on the elevator assembly 611, and the double-roller cooling assembly is placed under the extruder 5 in a clamping manner for cooling and forming the molten PVB film; wherein the double-roller cooling assembly comprises two cooling roller bodies, each cooling roller body comprises a barrel 33, and a water inlet assembly 32 and a water outlet assembly respectively arranged at the ends of the barrel 33; the barrel 33 comprises a water inlet inner sleeve 331, a cooling middle sleeve 332 and an embossed outer sleeve 333 sequentially distributed from the inside to the outside, wherein a partition plate 33 is provided in the water inlet inner sleeve 331 51, used to separate and form a plurality of cooling cavities, a through groove 352 is opened on the water inlet inner sleeve 331 corresponding to the cooling cavity; and a one-way valve plate assembly and a baffle assembly are arranged on the outer periphery of the water inlet inner sleeve 331, the one-way valve plate assembly is placed on the inner side of the baffle assembly and is located at the water outlet of the through groove 352; it also includes a transmission block 358 arranged between the water inlet inner sleeve 331 and the cooling middle sleeve 332, when the two embossed outer sleeves 333 rotate relative to each other in a clamping form, it is used for rotational embossing of the PVB film, and at the same time, the two water inlet inner sleeves 331 rotate toward each other, and under the cooperation of the transmission block 358 and the baffle assembly, the two water inlet inner sleeves 331 are relatively discharged to achieve rapid cooling of the clamping area of ​​the embossed outer sleeves 333.

[0040] In this embodiment, the slide 1 is used for the operation of the device, and the lift assembly 611 can be used to adjust the distance between the double-roll cooling assembly and the extruder 5, so as to adapt to different requirements of the PVB film extrusion operation, and the cylinder 33 where the double-roll cooling assembly is located can realize the replacement of cooling water through the continuous water injection and drainage process of the water inlet assembly 32 and the water outlet assembly, thereby ensuring its cooling effect;

[0041] The design highlight of the present invention is that: as is known, the cylinder 33 is composed of a water inlet inner sleeve 331, a cooling middle sleeve 332 and an embossed outer sleeve 333 which are distributed from the inside to the outside in sequence, combined with Figure 6 , 7 8, wherein the outer wall of the embossed outer sleeve 333 is engraved with an embossed pattern, and a structure for rapid replacement of cooling water is provided between the water inlet inner sleeve 331 and the cooling middle sleeve 332. The specific structure is as follows Fig.10 As shown, the partition plate 351 provided in the water inlet inner sleeve 331 is used to separate the inner cavity of the water inlet inner sleeve 331 and divide the inner cavity into a plurality of cooling cavities. Meanwhile, a through groove 352 is provided on the outer periphery of the water inlet inner sleeve 331 corresponding to the cooling cavities. In combination with the one-way valve plate assembly and the baffle assembly provided on the outer periphery of the water inlet inner sleeve 331, and the transmission block 358 provided between the water inlet inner sleeve 331 and the cooling middle sleeve 332, the transmission block 358 is placed in the middle position;

[0042] like Fig.10When the two water inlet inner sleeves 331 and the two embossed outer sleeves 333 are driven to rotate downward toward each other, the two embossed outer sleeves 333 complete the printing operation, and the water inlet inner sleeve 331 drives the baffle assembly to deflect and approach the water inlet inner sleeve 331 along the transmission block 358. At the moment when the baffle assembly is separated from the transmission block 358, the water pressure in the cooling cavity combined with the torsion spring of the baffle assembly can instantly push the one-way valve plate assembly and the baffle assembly to expand outward. In this process, the through groove 352 is opened, and the outward expansion of the baffle assembly can expand the space at the outlet of the through groove 352 and form a storage cavity. The water in the cooling cavity is quickly pressed to between the water inlet inner sleeve 331 and the cooling middle sleeve 332, so as to realize the rapid water injection and cooling on the opposite side of the cylinder 33. Then, this part of the cooling water heats up after cooling the PVB film. As the water inlet inner sleeve 331 further rotates, the baffle assembly pushes the heated water and moves it to the opposite side of the cylinder 33. In this process, the storage cavity is gradually reduced, and the one-way valve plate assembly is gradually closed. At the same time, the baffle assembly quickly squeezes the heated water and discharges it through the water outlet assembly to complete the rapid replacement process of the cooling water, thereby ensuring the cooling effect on the clamping side of the cylinder 33.

[0043] The present application realizes the process of rapid filling and replacement of cooling water by rapidly injecting water to cool the clamping sides of two cylinders 33 and rapidly squeezing out water on the opposite sides, thereby significantly improving the cooling effect of the cylinder 33 and effectively solving the problem of uneven temperature on the opposite sides of the existing cooling rollers.

[0044] Furthermore, the transmission block 358 is fixed on the inner side of the middle of the cooling sleeve 332 and is in the shape of a bull's horn; the baffle assembly includes a baffle body 356, wherein the end of the baffle body 356 is rotatably mounted with the water inlet inner sleeve 331 through a rotating shaft 355 provided on the water inlet inner sleeve 331; and a first torsion spring is provided between the rotating shaft 355 and the baffle body 356; when the water inlet inner sleeve 331 rotates to drive the baffle body 356 to run, the baffle body 356 gradually adheres to the water inlet inner sleeve 331 and is in the arc groove formed by the water inlet inner sleeve 331 and the transmission block 358. It opens instantly when leaving the arc groove, thereby quickly completing the water cooling on the opposite side of the water inlet inner sleeve 331; further, the one-way valve plate assembly includes a valve plate body 354, and one end of the valve plate body 354 is installed on one side of the water outlet of the through groove 352 through a pin shaft 353 and is rotatably installed therewith, and the other end thereof is overlapped on the other side of the water outlet of the through groove 352 and extends a distance, and a second torsion spring is arranged between the pin shaft 353 and the baffle body 356; it also includes an embedded groove 357 opened on the side wall of the baffle body 356, which is used to accommodate the valve plate body 354.

[0045] The transmission block 358 provided in the present application is fixed on the inner side of the middle of the cooling sleeve 332 and is in the shape of a bull horn as a whole. Specifically, the tip of the transmission block 358 faces outward, so when the water inlet inner sleeve 331 drives the baffle body 356 where the baffle assembly is located to gradually fit toward the water inlet inner sleeve 331 along the arc groove formed by the water inlet inner sleeve 331 and the transmission block 358, as the water inlet inner sleeve 331 further runs, at the moment when the baffle body 356 is separated from the transmission block 358, the valve plate body 354 and the baffle body 356 are quickly opened. In this process, the water pressure drives the valve plate body 354 to open, and the baffle The main body 356 is quickly extended and reset through the combined action of water pressure and the first torsion spring thereon to ensure the water injection speed on the opposite side of the cylinder 33. Subsequently, after this part of the cooling water heats up after cooling the PVB film, as the water inlet inner sleeve 331 further rotates, the baffle body 356 moved to the opposite side of the cylinder 33 quickly squeezes the heated water and discharges it through the water outlet assembly, while the valve plate body 354 gradually covers the water outlet end of the through groove 352 through the second torsion spring thereon and is gradually embedded in the embedded groove 357 to complete the rapid replacement process of the cooling water, thereby ensuring the cooling effect of the cylinder 33.

[0046] Furthermore, a guide groove 363 is provided on the inner wall of the cooling middle sleeve 332 , and the guide groove 363 is located at the opposite side of the cooling middle sleeve 332 .

[0047] Combination Fig.10 In order to extend the cooling time of the opposite side of the cylinder 33, the guide groove 363 is set so that when the opposite side of the cylinder 33 is quickly filled with water, the water flows through the guide groove 363 and turns back, thereby extending the time that the cooling water stays on the opposite side of the cylinder 33.
