[0028] This utility model proposes a calendering device, which aims to increase the smoothness of the glass forming process by providing smooth sections on the pressure roller, while reducing the cost of subsequent smoothing processes. Furthermore, by setting textured sections on the pressure roller, the friction between the pressure roller and the glass is increased to prevent the pressure roller from slipping due to its overall high smoothness during rolling, thereby further increasing the smoothness of the glass surface.
[0029] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the calendering apparatus 10 includes:
[0030] Mounting bracket 1;
[0031] The pressure roller assembly 2 includes a pressure roller 21 and a calendering frame 22. One side of the calendering frame 22 is mounted on the mounting frame 1. The pressure roller 21 is rotatably connected to the other side of the calendering frame 22. The outer peripheral wall of the pressure roller 21 is provided with two textured sections 213 spaced apart along its axial direction, and a smooth section 212 is provided between the two textured sections 213.
[0032] A drive assembly (not shown) is mounted on the mounting frame 1 and driven to the pressure roller 21.
[0033] In this embodiment, the calendering device 10 includes a mounting frame 1, a pressure roller assembly 2, and a drive assembly. The pressure roller assembly 2 includes a pressure roller 21 and a calendering frame 22. It should be noted that there are two calendering frames 22, which are spaced apart on both sides of the mounting frame 1. The two ends of the pressure roller 21 are rotatably mounted on each calendering frame 22. The drive assembly drives the pressure roller 21 to rotate so that the pressure roller 21 can calender and form the glass. It should be noted that the drive assembly is prior art and is not limited here. Furthermore, there are two calendering devices 10, and the two calendering devices 10 are arranged opposite to each other in the direction perpendicular to the glass movement. Thus, the two opposing pressure rollers 21 rotate in opposite directions so that the glass is formed and discharged between the two calendering rollers.
[0034] Specifically, the pressure roller assembly 2 includes a pressure roller 21 and a rolling frame 22. It should be noted that the pressure roller 21 is rotatably connected to the side of the rolling frame 22 away from the mounting frame 1, and the pressure roller 21 is located between the two rolling frames 22. At the same time, the outer peripheral wall of the pressure roller 21 is provided with two textured sections 213 at intervals along its axial direction, and each textured section 213 is located close to each rolling frame 22. A smooth section 212 is located between the two textured sections 213, so that the glass is rolled and discharged through the smooth section 212 to obtain glass with a smooth surface, thereby reducing the cost of subsequent smoothing processes. By providing textured sections 213 on the pressure roller 21, the friction between the pressure roller 21 and the glass is increased to prevent the pressure roller 21 from slipping during rolling due to its high overall smoothness, thereby further increasing the smoothness of the glass surface.
[0035] It should be further explained that the glass, after being extruded and formed by pressure rollers, will be cut to remove the textured sides of the glass, thereby obtaining the desired glass.
[0036] Please see Figure 1 and Figure 2 In one embodiment, the length of the pressure roller 21 is defined as d, the length of the smooth section 212 is defined as d1, d≤d1≤d, and the length of the textured section 213 is defined as d2, d1+2d2=d. By setting the length between the smooth section 212 and the textured section 213, the smoothness of the glass is increased, and the friction between the pressure roller 21 and the glass is ensured so that the glass can be discharged smoothly.
[0037] In this embodiment, in order to ensure the forming of glass, the length of the pressure roller 21 is defined as d, the length of the smooth section 212 is defined as d1, d≤d1≤d, and the length of the textured section 213 is defined as d2, d1+2d2=d. That is, by controlling the smooth section 212 and the textured section 213 within a certain length range, it is ensured that after the glass is rolled and formed by passing through the smooth section 212, a smooth surface glass is obtained. At the same time, the cost of subsequent smoothing processes is reduced. The textured section 213 increases the friction between the pressure roller 21 and the glass to prevent the pressure roller 21 from slipping due to its high overall smoothness during the rolling process.
[0038] It should be noted that each textured segment 213 has multiple spaced textures to ensure the friction between the pressure roller 21 and the glass, effectively preventing the pressure roller 21 from slipping during rolling due to its high overall smoothness. It should also be noted that the shape and number of textures are not limited in this application.
[0039] Please see Figure 1 and Figure 2In one embodiment, the calendering apparatus 10 further includes a water supply assembly (not shown). A cooling chamber 2111 with water inlet holes 211a and water outlet holes 211b at both ends is formed inside the pressure roller 21. One side of the water supply assembly is connected to the water inlet hole 211a to supply cooling water to the cooling chamber 2111. By supplying cooling water to the pressure roller 21 through the water supply assembly, the temperature of the surface of the pressure roller 21 is controlled, further increasing the smoothness of the glass surface and preventing the glass from sticking to the pressure roller 21 during the forming process.
[0040] In this embodiment, to further increase the smoothness of the glass surface, the rolling device 10 also includes a water supply component. The water supply component is connected to the pressure roller 21 to provide cooling water to the pressure roller 21, thereby effectively controlling the temperature of the pressure roller 21 and preventing the glass from sticking to the pressure roller 21 during the forming process. Specifically, a cooling chamber 2111 is formed inside the pressure roller 21, with inlet holes 211a and outlet holes 211b at both ends. One side of the water supply component is connected to the inlet hole 211a to provide cooling water to the cooling chamber 2111, thereby effectively controlling the surface temperature of the pressure roller 21 to further increase the smoothness of the flat glass surface and prevent the glass from sticking to the pressure roller 21 during the forming process. It should be noted that the water supply component is prior art, and will not be described in detail here.
[0041] It should be noted that the calendering apparatus 10 also includes a control component and a recovery component (not shown in the figure). The control component is electrically connected to the water supply component so that the water supply component can provide water with different flow rates and different amounts to the pressure roller 21 in a timely manner. The recovery component is connected to the water outlet 211b to recover the water that has passed through the cooling chamber. It should be noted that the recovery component and the control component are prior art and are not limited in this application.
[0042] Please see Figure 1 and Figure 2 In one embodiment, multiple cooling chambers 2111 are provided, and the multiple cooling chambers 2111 are arranged in a ring inside the pressure roller 21 so that water can quickly enter the cooling chambers 2111 to quickly control the temperature of the pressure roller 21.
[0043] In this embodiment, in order to quickly control the temperature of the pressure roller 21, multiple cooling chambers 2111 are provided, and the multiple cooling chambers 2111 are arranged in a ring inside the pressure roller 21. Similarly, multiple water inlets 211a and water outlets 211b are also provided. The multiple water inlets 211a are spaced apart on one end face of the pressure roller 21, and each water inlet 211a is connected to one side of the cooling chamber 2111. The multiple water outlets 211b are spaced apart on the other end face of the pressure roller 21, and each water outlet 211b is connected to the other side of the cooling chamber 2111. In this way, water can quickly enter the cooling chamber 2111, so as to quickly control the temperature of the pressure roller 21.
[0044] It should be noted that the cooling water supplied by the water supply assembly can be either cold water or boiling water. Since the pressure roller itself has a relatively high temperature, either cold or boiling water can serve a cooling purpose. Furthermore, by injecting boiling or cold water at different flow rates and in different amounts into the pressure roller 21, the surface temperature of the pressure roller 21 can be controlled.
[0045] Please see Figure 1 and Figure 2 In one embodiment, the calendering device 10 further includes a temperature detection element 3, which is installed on the mounting frame 1 and positioned above the pressure roller 21 to detect the temperature of the pressure roller 21. After detecting the temperature of the pressure roller 21, the temperature detection element 3 controls the water supply component to provide water of different flow rates and amounts to the pressure roller 21 in a timely manner through the control component.
[0046] Please see Figure 1 and Figure 2 In one embodiment, the calendering device 10 further includes a driving member 4, which is mounted on the mounting frame 1 and driven to be connected to the temperature detection member 3. The driving member 4 drives the temperature detection member 3 to move toward the pressure roller 21 so that the temperature detection member 3 is close to the pressure roller 21 to detect the temperature of the pressure roller 21, so as to control the temperature of the pressure roller 21 in real time, and to provide the water supply assembly with different flow rates and different amounts of water to the pressure roller 21 in a timely manner according to the actual situation.
[0047] In this embodiment, the calendering device 10 further includes a driving member 4, which is mounted on the mounting frame 1 and driven to connect to the temperature detection member 3. The driving member 4 drives the temperature detection member 3 to move toward the pressure roller 21 so that the temperature detection member 3 can detect the temperature of the pressure roller 21. That is, by driving the temperature detection member 3 toward the pressure roller 21 through the driving member 4 so that the temperature detection member 3 is close to the pressure roller 21, the temperature of the pressure roller 21 can be obtained in real time without affecting the rotation of the pressure roller 21.
[0048] Please see Figure 1 and Figure 2In one embodiment, the driving component 4 includes a rotating handle 41 and a lifting rod 42. One end of the lifting rod 42 is connected to the rotating handle 41, and the other end of the lifting rod 42 is threadedly connected to the mounting frame 1 and passes through the mounting frame 1, connecting to the temperature sensing element 3, thereby allowing the temperature sensing element 3 to move closer to or away from the pressure roller 21. It should be noted that the lifting rod 42 is a screw, and a threaded hole is provided on the mounting frame 1. This threaded hole is threadedly connected to the lifting rod 42, so that when the handle 41 is rotated, the lifting rod 42 can be moved on the mounting frame 1. During the movement of the lifting rod 42, the temperature sensing element 3 also moves towards the pressure roller 21, allowing the temperature sensing element 3 to move closer to or away from the pressure roller 21. When it moves closer, the real-time temperature of the pressure roller 21 can be measured. Furthermore, the temperature sensing element 3 does not affect the rotation of the pressure roller 21 during operation.
[0049] Please see Figure 1 and Figure 2 In one embodiment, the calendering device 10 further includes a connecting plate 5. One side of the connecting plate 5 is connected to the lifting rod 42, and the other side of the connecting plate 5 is movably covered on part of the outer peripheral wall of the pressure roller 21. The temperature detection element 3 is disposed on the side of the connecting plate 5 facing the pressure roller 21. By setting the connecting plate 5, the temperature detection element 3 can be better close to the outer peripheral wall of the pressure roller 21, so that the temperature detection element 3 can detect the temperature of the pressure roller 21 without affecting the rotation of the pressure roller 21.
[0050] In this embodiment, to facilitate the operation of the temperature detection element 3, the calendering device 10 also includes a connecting plate 5. One side of the connecting plate 5 is connected to the lifting rod 42, while the other side of the connecting plate 5 is movably covered on part of the outer peripheral wall of the pressure roller 21. It should be noted that the connecting plate 5 moves closer to or further away from the pressure roller 21 under the drive of the lifting rod 42 and the rotating handle 41. At the same time, the temperature detection element 3 is disposed on the side of the connecting plate 5 facing the pressure roller 21. Thus, under the drive of the connecting plate 5, the temperature detection element 3 can be better attached to the outer peripheral wall of the pressure roller 21, so that the temperature detection element 3 can detect the temperature of the pressure roller 21 without affecting the rotation of the pressure roller 21.
[0051] Please see Figure 1 and Figure 2 In one embodiment, the connecting plate 5 is arc-shaped. This arrangement ensures that the connecting plate 5 and the temperature detection element 3 are close to the outer wall of the pressure roller 21, and the temperature of the outer wall of the pressure roller 21 is measured by the temperature detection element 3, thereby improving the accuracy of the temperature measurement of the pressure roller 21.
[0052] Please see Figure 1 and Figure 2In one embodiment, the driving component 4 further includes a horizontal plate 43, which is disposed on the side of the lifting rod 42 away from the rotating handle 41. Multiple temperature detection components 3 are provided, and multiple connecting plates 5 are provided. The multiple connecting plates 5 are arranged at intervals along the length direction of the horizontal plate 43. Each temperature detection component 3 is disposed on each connecting plate 5. By setting multiple temperature detection components 3, the temperature of the outer wall of the pressure roller 21 is measured, thereby improving the accuracy of measuring the temperature of the pressure roller 21.
[0053] In this embodiment, to improve the accuracy of temperature detection of the pressure roller 21 by the temperature detection element 3, the driving element 4 also includes a horizontal plate 43. The horizontal plate is set on the side of the lifting rod 42 away from the rotating handle 41, and multiple temperature detection elements 3 are provided. Similarly, multiple connecting plates 5 are also provided, such as two, three or more. The multiple connecting plates 5 are arranged at intervals along the length direction of the horizontal plate 43. Similarly, each temperature detection element 3 is set on each connecting plate 5. Thus, under the drive of the rotating handle 41 and the lifting rod 42, the multiple temperature detection elements 3 move simultaneously toward the pressure roller 21 to get closer to or away from the pressure roller 21. The multiple temperature detection elements 3 can simultaneously come into contact with the outer peripheral wall of the pressure roller 21 and simultaneously measure the temperature of the outer wall of the pressure roller 21. This allows for precise control of the surface temperature of the pressure roller 21, further increasing the smoothness of the flat glass surface and preventing the glass from sticking to the pressure roller 21 during the forming process.
[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
