Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PVB material cooling, in particular to a segmented cooling and shaping water tank based on PVB material processing. BACKGROUND

[0002] PVB material has broad application prospects in many industries such as building, automobile and photovoltaic due to its excellent performance characteristics. In the future, with the development of various industries and the progress of technology, it will develop towards green environmental protection, customization and intelligentization. At the same time, with the diversified application of materials, the performance requirements of materials are also constantly diversified and innovated. When producing PVB film, the temperature of the material after coming out of the casting machine is about 180℃, and finally needs to be cooled to room temperature (about 30℃) by a cooling water tank for shaping, and then enters the next drying process.

[0003] Since the existing initial condition only uses one cooling water tank for cooling, the material is directly cooled from high temperature to low temperature, and the rapid cooling causes the material's own performance to change dramatically, resulting in poor performance of the material's own tension, stress and plasticity, affecting the application of the back end.

[0004] Therefore, according to the application needs, two or more cooling water tanks are used for segmented temperature control to achieve the effect of slow cooling to realize the stability of the material performance, which results in a large occupied area, and the cooling liquid in the low-temperature cooling water tank cannot be used in the high-temperature cooling water tank. Therefore, a segmented water tank is designed, which is a ladder type water tank with multiple cooling cavities with gradually increasing depths. The water in the uppermost cooling cavity overflows into the lower cooling cavity, and then gradually overflows to fully utilize the cooling liquid and reduce the occupied area. However, there is a problem that when the cooling cavity is full, the newly entered cooling liquid enters from the top and has not fully mixed with the cooling liquid at the bottom of the cooling cavity before overflowing from the top to the next cooling cavity, resulting in the temperature of the cooling liquid at the top of the cooling cavity being lower than that of the cooling liquid at the bottom of the cooling cavity, which affects the forming quality of the PVB film.

[0005] The above information disclosed in the background section is only used to strengthen the understanding of the background of the present disclosure, so it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] The purpose of the present application is to design a cooling and shaping water tank with small occupied area during work, which can fully utilize the cooling liquid for segmented cooling, and the cooling liquid at the top of the cooling cavity can be fully mixed with the cooling liquid at the bottom of the cooling cavity before overflowing, to solve the above problems in the art.

[0007] In order to achieve the above object, the present application provides the following technical scheme: A segmented cooling and shaping water tank based on PVB material processing is used for cooling of PVB film, comprising a water tank body, the water tank body is internally fixedly provided with N length-increasing partition plates, the partition plates divide the water tank into N+1 cooling cavities, each cooling cavity is provided with a fluctuation module fixedly connected with the water tank body, the fluctuation module divides the cooling cavity into a liquid inlet cavity and a liquid outlet cavity in communication at the bottom, a power assembly for driving the fluctuation module to reciprocating swing is installed at the top of the fluctuation module, a plurality of roller shafts are rotatably installed in the water tank body, the PVB film is connected with the roller shafts and sequentially enters the liquid inlet cavity and the liquid outlet cavity, and the liquid outlet cavity and the liquid inlet cavity are sequentially divided into a liquid outlet outer cavity, a liquid outlet inner cavity, a liquid inlet inner cavity and a liquid inlet outer cavity.

[0008] Cooling liquid is continuously injected into the liquid inlet cavity at the highest position, and the cooling liquid is pressed into the liquid outlet cavity under the action of atmospheric pressure until it overflows into the adjacent liquid inlet cavity to cool the higher temperature part of the PVB film, and the fluctuation module continuously swings to mix the cooling liquid in the liquid outlet outer cavity and the liquid outlet inner cavity, and the liquid inlet inner cavity and the liquid inlet outer cavity, so as to make the temperatures of the liquids on both sides of the PVB film tend to be the same.

[0009] Preferably, the number of roller shafts is N+1, and four roller shafts correspond to one cooling cavity, two roller shafts are respectively located at the bottom of the liquid inlet cavity and the liquid outlet cavity, and the other two roller shafts are located above the partition plate.

[0010] Preferably, the height of the liquid inlet cavity in the cooling cavity is higher than the height of the liquid outlet cavity.

[0011] Preferably, the volumes of the N+1 cooling cavities increase in sequence, and the lengths of time for the PVB film to stay and cool in the cooling cavities increase in sequence.

[0012] Preferably, the fluctuation module comprises two connecting plates fixedly connected with the inner wall of the water tank body, two swing plates rotatably installed on the opposite sides of the two connecting plates, and a flexible plate fixedly connected between the two swing plates, and the length of the flexible plate is greater than the distance between the two swing plates.

[0013] Preferably, the power assembly comprises a swing rod rotatably installed at the top of the connecting plate, a transmission rod rotatably installed at the end of the swing rod, a sliding groove formed in the swing rod, a sliding rod slidably installed in the sliding groove, a driven wheel fixedly installed at the bottom of the sliding rod, a transmission shaft fixedly installed in the driven wheel, and a driving wheel engaged on one side of the driven wheel, the transmission shaft is rotatably connected with the connecting plate, and the transmission rod is fixedly connected with the top of the swing plate.

[0014] Preferably, the power assembly further comprises an input shaft fixedly installed on the top of the driving wheel, and a positioning rod rotatably installed outside the input shaft and fixedly connected with the inner wall of the water tank body.

[0015] Preferably, the material of the flexible plate comprises silicone rubber, natural rubber and nitrile rubber.

[0016] Preferably, a backflow cooling tank is fixedly connected to one side of the water tank body and adjacent to the liquid outlet cavity with the lowest height.

[0017] In the above technical solution, the present application provides the following technical effects and advantages:

[0018] By arranging N separation plates with increasing lengths in the water tank body, the cooling cavities with increasing heights are formed inside the water tank, so that when the PVB film enters the cooling cavities for heat exchange and cooling, as long as the room temperature cooling liquid is continuously injected into the highest cooling cavity, the cooling liquid will overflow into the adjacent cooling cavity after absorbing heat to cool the cooling liquid with a higher temperature, thereby ensuring that the temperature of the cooling liquid in each cooling cavity maintains a temperature difference and the PVB film is cooled in a segmented manner.

[0019] By arranging a fluctuation module in the cooling cavity, the cooling cavity is divided into a liquid inlet cavity and a liquid outlet cavity, so that under the action of atmospheric pressure, the liquid will not directly overflow from the top of the cooling cavity after overflowing into the liquid inlet cavity, but will overflow through the top of the liquid inlet cavity, the bottom of the liquid inlet cavity, the bottom of the liquid outlet cavity and the top of the liquid outlet cavity in turn, thereby avoiding the accumulation of the temperature of the cooling liquid at the bottom of the cooling cavity, causing the temperature at the bottom of the cooling cavity to be higher than the temperature at the top of the cooling cavity, and affecting the forming quality.

[0020] Meanwhile, the present application rotatably installs multiple roller shafts inside the water tank, so that when the PVB film enters different liquid inlet cavities and liquid outlet cavities for cooling, the liquid outlet cavity and the liquid inlet cavity will be divided into a liquid outlet outer cavity, a liquid outlet inner cavity, a liquid inlet inner cavity and a liquid inlet outer cavity in turn, causing the cooling liquid on both sides of the PVB film to only exchange heat directly through the gap between the PVB film and the water tank body. Therefore, we set up a power assembly to drive the oscillating plate to reciprocate, promote the S-shaped fluctuation of the flexible plate, drive the cooling liquid to flow to the same side, and promote the mixing of the cooling liquid on both sides of the PVB film, thereby improving the segmented cooling forming quality.

DETAILED DESCRIPTION

[0029] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0031] The present application provides a cooling device for a water tank, which comprises a water tank body, a cooling liquid, a wave module and a power assembly. Figures 1-5The illustrated segmented cooling and shaping water tank based on PVB material processing is mainly used for segmented cooling of PVB film 1, comprising a water tank body 2 in the prior art, which has an upwardly open cavity with cooling liquid 3 therein, and N length-increasing partition plates 4 are fixedly installed inside the water tank body 2, the bottom surface of the partition plate 4 is fixedly connected with the bottom surface of the cavity of the water tank body 2, and the top surface height increases successively, so that the cavity of the water tank body 2 is divided into N+1 cooling cavities 5, and the height in each cooling cavity 5 increases successively, so that when the cooling liquid 3 is injected into the highest cooling cavity 5, once the cooling liquid 3 in the cooling cavity 5 is full, it will overflow into the adjacent cooling cavity 5 with lower height, but there is a situation that as the cooling liquid 3 in the cooling cavity 5 is filled, the overflowed cooling liquid 3 is mostly the cooling liquid 3 just entering the top of the cooling cavity 5, and the cooling liquid 3 at the bottom of the cooling cavity 5 is difficult to flow into the adjacent cooling cavity 5.

[0032] Therefore, a fluctuation module 6 is installed in the cooling cavity 5, which is composed of two connection plates 61 fixedly connected with the inner wall of the water tank body 2, two swing plates 62 rotatably installed on one side of the two connection plates 61, and a flexible plate 63 fixedly installed between the two swing plates 62, and the flexible plate 63 includes but is not limited to silicone rubber, natural rubber and nitrile rubber materials, which has good flexibility, chemical stability and easy integration, and the fluctuation module 6 divides the cooling cavity 5 into a liquid inlet cavity 51 and a liquid outlet cavity 52 which are connected at the bottom, and the height of the liquid inlet cavity 51 is higher than that of the liquid outlet cavity 52 by setting the height of the fluctuation module 6, so that once the cooling liquid 3 overflows from the previous liquid outlet cavity 52 into the current liquid inlet cavity 51, because the liquid inlet cavity 51 and the liquid outlet cavity 52 form a U-shaped structure, under the action of atmospheric pressure, the liquid level of the cooling liquid 3 in the liquid inlet cavity 51 and the liquid outlet cavity 52 is driven to be parallel, so that the entering cooling liquid 3 in the liquid inlet cavity 51 flows to the bottom of the liquid inlet cavity 51 under the action of atmospheric pressure, and then flows upward from the bottom of the liquid outlet cavity 52, and finally overflows and is discharged into the liquid inlet cavity 51 of the next cooling cavity 5, thereby avoiding the situation that the amount of liquid at the top of the cooling cavity 5 discharged into the next cooling cavity 5 is greater than the amount of liquid at the bottom of the cooling cavity 5 flowing into the next cooling cavity 5, and preventing heat accumulation in the cooling liquid 3 at the bottom of the cooling cavity 5.

[0033] A plurality of rollers 8 are rotatably installed in the water tank body 2, and four rollers 8 are provided for each cooling cavity 5, two of which are respectively located at the bottom of the liquid inlet cavity 51 and the liquid outlet cavity 52, and the other two are located above the partition plate 4. The PVB film 1 is rolled and connected on the rollers 8 and sequentially enters the liquid inlet cavity 51 and the liquid outlet cavity 52 in each cooling cavity 5, thereby sequentially dividing the liquid storage chamber and the liquid inlet cavity 51 into the liquid outlet outer cavity 521, the liquid outlet inner cavity 522, the liquid inlet inner cavity 511 and the liquid inlet outer cavity 512. The liquid outlet inner cavity 522 and the liquid inlet inner cavity 511 are close to the flexible plate 63, and the liquid outlet outer cavity 521 and the liquid inlet outer cavity 512 are away from the flexible plate 63. The internal cooling liquid 3 respectively contacts the top surface and the bottom surface of the PVB film 1. Since the PVB film 1 itself hinders the cooling liquid 3 from passing through, the cooling liquid 3 can only pass through the gap between the PVB film 1 and the inner wall of the water tank body 2, that is, the cooling liquid 3 between the liquid outlet outer cavity 521 and the liquid outlet inner cavity 522 and the cooling liquid 3 between the liquid inlet inner cavity 511 and the liquid inlet outer cavity 512 can only mix through the gap, and the cooling liquid 3 between the liquid outlet outer cavity 521 and the liquid inlet outer cavity 512 and the cooling liquid 3 between the liquid outlet inner cavity 522 and the liquid inlet inner cavity 511 can also mix at the bottom. This will cause a problem that when the cooling liquid 3 overflows from the previous liquid outlet cavity 52, it will first enter the next liquid inlet outer cavity 512, then part of the cooling liquid 3 mixes with the cooling liquid 3 in the liquid inlet inner cavity 511 through the gap, and the remaining liquid enters the liquid outlet outer cavity 521 from the bottom, and then overflows. The cooling liquid 3 in the liquid outlet outer cavity 521 flows out first, followed by the cooling liquid 3 in the liquid outlet inner cavity 522, which will cause the flow rate of the cooling liquid 3 in the liquid outlet outer cavity 521 and the liquid inlet outer cavity 512 to be greater than the flow rate of the cooling liquid 3 in the liquid inlet inner cavity 511 and the liquid outlet inner cavity 522. When the PVB film 1 enters the cooling cavity 5, heat is transferred to the cooling liquid 3 through heat exchange. At this time, due to the fast flow rate of the cooling liquid 3 in the liquid inlet outer cavity 512 and the liquid outlet outer cavity 521 and the slow flow rate of the cooling liquid 3 in the liquid inlet inner cavity 511 and the liquid outlet inner cavity 522, the temperature of the cooling liquid 3 in the liquid inlet inner cavity 511 and the liquid outlet inner cavity 522 is higher than that of the cooling liquid 3 in the liquid inlet outer cavity 512 and the liquid outlet outer cavity 521, which will cause the cooling speed of the PVB film 1 on both sides to be different, affecting the cooling and forming quality of the PVB film 1.

[0034] Therefore, a power assembly 7 is installed on each undulating module 6 to drive the flexible plate 63 in the undulating module 6 to make S-shaped motion, as shown in Figure 1 and Figure 4 Figure 1 ​Each of the transverse waves forms a force on the cooling liquid 3 in the liquid inlet cavity 511 and the liquid outlet cavity 522, so that the cooling liquid 3 in this part flows to the same side, thereby accelerating the liquid exchange speed between the liquid outlet cavity 521 and the liquid outlet cavity 522, and the liquid inlet cavity 511 and the liquid inlet cavity 512, thereby reducing the temperature difference between the cooling liquid 3. The power assembly 7 mainly drives the swing plate 62 to reciprocating swing. The reciprocating motion mechanism used herein includes a swing rod 71 rotatably mounted on the top of the connecting plate 61, a transmission rod 72 rotatably mounted at the end of the swing rod 71, a sliding groove 73 formed in the swing rod 71, a sliding rod 74 slidably mounted in the sliding groove 73, a driven wheel 75 fixedly mounted at the bottom of the sliding rod 74, a transmission shaft 76 fixedly mounted in the driven wheel 75, a driving wheel 77 engaged on one side of the driven wheel 75, an input shaft 78 fixedly mounted on the top of the driving wheel 77, and a positioning rod 79 rotatably connected with the input shaft 78. The positioning rod 79 is fixedly connected with the inner wall of the water tank body 2. The transmission shaft 76 is rotatably connected with the connecting plate 61. The transmission rod 72 is fixedly connected with the top of the swing plate 62. The input shaft 78 provides rotary power to the input shaft 78. The input shaft 78 drives the driving wheel 77 to rotate. The driving wheel 77 drives the driven wheel 75 to rotate. The driven wheel 75 drives the sliding rod 74 to rotate. The sliding rod 74 drives the swing rod 71 to reciprocating swing through cooperation with the sliding groove 73. The swing rod 71 drives the swing plate 62 to reciprocating swing through the transmission rod 72. Thus, the flexible plate 63 makes S-shaped motion. The flexible plate 63 can push the adjacent cooling liquid 3 to flow to the same side. Finally, the backflow cooling tank 9 is fixedly connected on one side of the water tank body 2. The backflow cooling tank 9 is adjacent to the lowest liquid outlet cavity 52, so as to recycle the cooling liquid 3 overflowing from the water tank body 2.

[0035] The overall working process of the water tank is as follows: the cooling liquid 3 at room temperature is continuously introduced into the liquid inlet cavity 512 in the highest cooling cavity 5. The temperature of the cooling liquid 3 can be adjusted according to the process requirements. Then the cooling liquid 3 is guided by the reciprocating swing wave module 6 when entering the liquid outlet cavity 52 and the liquid inlet cavity 51, so as to promote the mixing of the cooling liquid 3, ensure that the temperature difference between the two sides of the PVB film 1 is small, improve the cooling forming quality, and absorb heat. The cooling liquid 3 overflowing into the cooling cavity 5 with a lower height exchanges heat with the PVB film 1 with a higher temperature, and then overflows into the next cooling cavity 5, until it overflows into the backflow cooling tank 9. This makes the PVB film 1 enter the cooling cavities 5 with gradually increasing heights after entering the water tank body 2, and exchanges heat with the cooling liquid 3 with gradually decreasing temperatures, and finally cools to the required temperature, and moves from the highest roller 8 to the next drying process.

[0036] It is important to note that the construction and arrangement of the application shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described in the application.
