At present, the production process of photovoltaic glass mainly includes key steps such as melting, rolling, and annealing. Melting: Melting the raw materials at high temperature to obtain uniform glass liquid; rolling: Passing the molten glass liquid through a rolling machine to form a glass ribbon with a certain thickness and flatness; annealing: Heat treatment of the rolled glass ribbon to eliminate internal stress and improve the stability and mechanical strength of the product; In the production process of photovoltaic glass, the rolling step is particularly critical.

By adjusting the distance between the upper pressure roller 208 and the lower pressure roller 205, the thickness of the rolled glass ribbon can be accurately controlled (the smaller the spacing, the thinner the glass ribbon; conversely, the thicker it is).

[0034] See also Figure 4 As shown, the limiting mechanism includes a connecting plate 11 and a limiting plate Ⅰ12; the two connecting plates 11 are symmetrically arranged on the right sides of the front and rear sides of the rotating frame 6; the limiting plates Ⅰ12 are connected to the telescopic rods of the two electric push rods 5; when the rotating frame 6 is rotating, the rotating frame 6 will drive the connecting plate 11 to rotate, and when the connecting plate 11 contacts the limiting plate Ⅰ12, the limiting plate Ⅰ12 will prevent the connecting plate 11 from continuing to rotate, so that the rotating frame 6 stops rotating, thereby limiting the rotation angle of the rotating frame 6.

[0035] See also Figure 5As shown, the moving mechanism includes a servo motor Ⅰ13 and a screw rod 14; two servo motors Ⅰ13 are symmetrically installed on the upper right side of the support frame Ⅰ3; two screw rods 14 are symmetrically installed on the upper side of the support frame Ⅰ3, and the two screw rods 14 are respectively connected to the output shafts of the two servo motors Ⅰ13, and the two screw rods 14 are both threadedly connected to the slide plate 4.

[0036] See also Figure 6-Figure 11 As shown, the blocking mechanism includes a blocking frame 15, a connecting ring 16, a heating element 17, a stopper 18, a graphite sheet 19, a support frame II 20, a sliding seat 21, a hydraulic cylinder II 22, a threaded rod 23, a servo motor II 24, a gear 25 and a rack 26; the blocking frame 15 is placed on the lip brick system 204 of the calender, and the blocking frame 15 needs to be made of a high-temperature resistant alloy. The blocking frame 15 is used to block the molten glass liquid; four connecting rings 16 are symmetrically arranged on the top of the blocking frame 15; the heating element 17 is installed on the blocking Inside the frame 15, the heating element 17 is a molybdenum heating element, which has an S-shaped structure. Setting the molybdenum heating element into an S-shaped structure can increase the heat dissipation area and evenly distribute the heat; limit blocks 18 are arranged at intervals in the blocking frame 15, and the limit blocks 18 are used to limit the heating element 17, so as to stabilize the heating element 17; the inner wall of the blocking frame 15 is connected to a graphite sheet 19, and the graphite sheet 19 is used to separate the blocking frame 15 from the heating element 17. By using the graphite sheet 19 to separate the blocking frame 15 from the heating element 17, It can prevent short circuit between the heating element 17 and the blocking frame 15, ensure the safety of the circuit, and the graphite sheet 19 can reduce the stress between the heating element 17 and the blocking frame 15 caused by different thermal expansion coefficients; the support frame Ⅱ20 is installed on the left rear side of the top of the bottom plate 1, and the upper front part of the support frame Ⅱ20 is connected to the frame Ⅱ202; the sliding seat 21 is slidably set on the support frame Ⅱ20; the two hydraulic cylinders Ⅱ22 are symmetrically installed on the sliding seat 21; the telescopic rods of the two hydraulic cylinders Ⅱ22 are both threadedly connected with threaded rods 23, The threaded rod 23 on the front side passes through the two connecting rings 16 on the front side, and the threaded rod 23 on the rear side passes through the two connecting rings 16 on the rear side. The threaded rod 23 is driven to move upward by the hydraulic cylinder Ⅱ 22, so that the threaded rod 23 can drive the connecting rings 16 and the blocking frame 15 to move upward, so that the blocking frame 15 no longer blocks the molten glass liquid; the servo motor Ⅱ 24 is installed on the right side of the sliding seat 21; the gear 25 is connected to the output shaft of the servo motor Ⅱ 24; the rack 26 is installed on the upper right side of the support frame Ⅱ 20, and the gear 25 is meshed with the rack 26.

[0037] When in use, align the liquid outlet on the kiln mouth with the blocking frame 15 on the frame II 202, and then heat the inside of the blocking frame 15 through the heating element 17, so that the heating element 17 conducts heat to the outer wall of the blocking frame 15 through the graphite sheet 19, so that the temperature of the outer wall of the blocking frame 15 gradually increases (the temperature of the outer wall of the blocking frame 15 needs to be higher than the solidification point of the glass), and the slider 207 and the upper pressure roller 208 are driven up and down by the hydraulic cylinder I 206 to adjust the distance between the upper pressure roller 208 and the lower pressure roller 205, so as to control the thickness of the glass ribbon rolled out by the calender; after that, when the molten glass liquid in the kiln mouth flows out from the liquid outlet, the blocking frame 15 will block the molten glass liquid, and due to the distance between the outer wall of the blocking frame 15 and the molten glass liquid The temperature difference is small, so that the molten glass can flow on the outer wall of the blocking frame 15, so that the molten glass will not solidify and adhere to the outer wall of the blocking frame 15; when the molten glass starts to be rolled, the threaded rod 23 is driven to move upward by the hydraulic cylinder II 22, so that the threaded rod 23 drives the connecting ring 16 and the blocking frame 15 to move upward, so that the blocking frame 15 no longer blocks the molten glass, and then the gear 25 is driven to rotate by the servo motor II 24, so that the rack 26 drives the gear 25 to move backward, thereby driving the servo motor II 24, the sliding seat 21, the hydraulic cylinder II 22, the threaded rod 23, the connecting ring 16 and the blocking frame 15 to move backward, and at the same time, the heating element 17 stops heating inside the blocking frame 15, so that the outer wall of the blocking frame 15 is naturally cooled;When the blocking frame 15 no longer blocks the molten glass, the molten glass will flow into the lip brick system 204 of the calender, and then the molten glass will pass between the upper pressing roller 208 and the lower pressing roller 205, so that the upper pressing roller 208 and the lower pressing roller 205 will calender the molten glass, so that the molten glass will form a glass ribbon and gradually transport to the right. When the head end of the glass ribbon is transported to the right, the head end of the glass ribbon will form an arc surface with a long middle and gradually shorter sides. Therefore, the head end of the glass ribbon will first contact with the supporting block II 902. When the head end of the glass ribbon falls on the supporting block II 902, the head end of the glass ribbon will push the supporting block II 902 to move to the right, and the multi-section telescopic long rod 8 and the spring I 10 will be compressed. When the head end of the glass ribbon falls on the supporting block II 902, the head end of the glass ribbon will push the supporting block II 902 to move to the right. When the glass ribbon is on block Ⅰ901, the servo motor Ⅰ13 drives the screw rod 14 to rotate, so that the screw rod 14 drives the slide plate 4 to move right, thereby driving the electric push rod 5, the rotating frame 6, the roller 7, the multi-section telescopic long rod 8, the supporting block Ⅰ901 and the supporting block Ⅱ902 to move right (the speed of the supporting block Ⅰ901 and the supporting block Ⅱ902 moving to the right needs to be controlled to be consistent with the speed of the glass ribbon being conveyed to the right), so that the supporting block Ⅰ901 and the supporting block Ⅱ902 continue to drag the head end of the glass ribbon to move right, and when the roller 7 moves to the right, the rotating frame 6 and the roller 7 are driven to move downward by the electric push rod 5 at the same time, so that the roller 7 is always in contact with the inclined surface at the top of the frame Ⅰ201. When the roller 7 on the right side is lifted off the top of the frame Ⅰ201, the rotating frame 6 and the roller 7 are driven downward by the electric push rod 5, so that the roller 7 is always in contact with the inclined surface at the top of the frame Ⅰ201. When the inclined surface rolls to the plane, the electric push rod 5 stops driving the rotating frame 6 and the roller 7 to move downward, and then the roller 7 on the left gradually rolls from the inclined surface at the top of the frame Ⅰ201 to the plane; when the supporting block Ⅰ901 and the supporting block Ⅱ902 continue to drag the head end of the glass ribbon to the right to the specified position (this period of time is mainly to wait for the glass ribbon to gradually form and become more stable), the servo motor Ⅰ13 drives the screw rod 14 to rotate faster, so that the screw rod 14 drives the slide plate 4 to move faster to the right, thereby driving the electric push rod 5, the rotating frame 6, the roller 7, the multi-section telescopic long rod 8, the supporting block Ⅰ901 and the supporting block Ⅱ902 to move faster to the right, so that the supporting block Ⅰ901 and the supporting block Ⅱ902 are separated from the head end of the glass ribbon. The first end of the glass ribbon falls down onto the conveying roller 203, and the conveying roller 203 then conveys the glass ribbon. When the supporting block II 902 separates from the first end of the glass ribbon, the spring I 10 and the multi-section telescopic rod 8 return to their original state, and the spring I 10 drives the supporting block II 902 to move to the left and reset. Then, the electric push rod 5 drives the rotating frame 6 and the roller 7 to move upward and reset, so that the roller 7 is separated from the top of the frame I 201, and the rotating frame 6, the multi-section telescopic rod 8, the supporting block I 901 and the supporting block II 902 do not affect the subsequent conveying of the glass ribbon by the conveying roller 203. During this period, the limiting plate I 12 limits the connecting plate 11, thereby limiting the rotating frame 6, so that the rotating frame 6 remains in a horizontal state. ;

[0038] After that, when all the molten glass liquid has completed the calendering process and is transported by the conveying roller 203, the servo motor Ⅰ13 drives the screw rod 14 to reverse and reset, so that the screw rod 14 drives the slide plate 4 to move to the left and reset, thereby driving the electric push rod 5, the rotating frame 6, the roller 7, the multi-section telescopic long rod 8, the supporting block Ⅰ901 and the supporting block Ⅱ902 to move to the left and reset. When the roller 7 contacts the inclined surface at the top of the frame Ⅰ201, the inclined surface at the top of the frame Ⅰ201 will drive the rotating frame 6 and the connecting plate 11 to reverse and reset, so that the connecting plate 11 is separated from the limit plate Ⅰ12; then the servo motor Ⅱ24 drives the gear 25 to reverse and reset, so that the rack 26 drives the gear 25 to move forward and reset, thereby driving the servo motor Ⅱ24, the sliding seat 21, the hydraulic cylinder Ⅱ22, The threaded rod 23, the connecting ring 16 and the blocking frame 15 are moved forward and reset, and then it is selected whether to repair the blocking frame 15 according to the needs. If the blocking frame 15 needs to be repaired, the threaded rod 23 is twisted out of the telescopic rod of the hydraulic cylinder II 22, so that the threaded rod 23 passes through the connecting ring 16, and then the blocking frame 15 can be removed for repair. After the blocking frame 15 is repaired, the blocking frame 15 is put back to its original position, and then the threaded rod 23 is twisted back onto the telescopic rod of the hydraulic cylinder II 22, so that the threaded rod 23 is re-inserted into the connecting ring 16; if the blocking frame 15 does not need to be repaired, no additional operation is required; then the hydraulic cylinder II 22 drives the threaded rod 23 to move downward and reset, so that the threaded rod 23 drives the connecting ring 16 and the blocking frame 15 to move downward and reset.

[0039] See also Fig.12 and Fig.13 As shown, it also includes a cooling mechanism, which includes a connecting frame 27, a limit plate II 28, a spring II 29 and a water pipe 30; the connecting frame 27 is connected between the support frame II 20 and the frame II 202; two limit plates II 28 are symmetrically slidably arranged on the inner side of the connecting frame 27, and the front side corners of the two limit plates II 28 are both provided with arc surfaces; one end of the spring II 29 is connected to the side of the two limit plates II 28 away from each other, and the other end of the spring II 29 is connected to the inner side of the connecting frame 27; the side of the two limit plates II 28 away from each other is installed with a water pipe 30, and the water pipe 30 is S-shaped. Setting the water pipe 30 into an S-shaped structure can increase the heat absorption area and uniform heat absorption.

[0040] When in use, clean water is introduced into one end of the water pipe 30, and then the clean water in the water pipe 30 is led out from the other end, so that the clean water flows in the water pipe 30; when the sliding seat 21 drives the hydraulic cylinder II 22, the threaded rod 23, the connecting ring 16 and the blocking frame 15 to move backward, the blocking frame 15 will enter the connecting frame 27, and when the blocking frame 15 contacts the arc surface on the limit plate II 28, the blocking frame 15 will squeeze the two limit plates II 28 to move away from each other, and the spring II 29 is compressed. By utilizing the elastic force of the spring II 29, the spring II 29 can apply pressure to the limit plate II 28, so that the limit plate II 28 is tightly attached to the outer wall of the blocking frame 15, and then the clean water in the water pipe 30 is used to absorb heat and cool the limit plate II 28, and then by The limiting plate II 28 absorbs heat and cools the blocking frame 15, so that the cooling of the blocking frame 15 can be accelerated (cooling the blocking frame 15 can prevent the blocking frame 15 from being in a high temperature state for a long time, thereby avoiding damage to nearby operators and instruments; and the cooled blocking frame 15 can reduce operating risks and facilitate operators to repair the blocking frame 15); thereafter, when the sliding seat 21 drives the hydraulic cylinder II 22, the threaded rod 23, the connecting ring 16 and the blocking frame 15 to move forward and reset, the blocking frame 15 will leave the connecting frame 27, and when the blocking frame 15 is separated from the limiting plate II 28, the spring II 29 returns to its original state, and the spring II 29 drives the two limiting plates II 28 to move to the side close to each other and reset.

[0041] See also Fig.14 As shown, a control mechanism is also included, which includes a distance sensor I31, a distance sensor II32 and a controller 33; the two distance sensors I31 are respectively installed on the top of the two supporting blocks I901, and the distance sensor I31 is used to sense the distance between the glass belt; the distance sensor II32 is installed in the middle of the upper right side of the support frame I3, and the distance sensor II32 is used to sense the distance between the slide plate 4; the controller 33 is installed in the front of the upper right side of the support frame I3, and the distance sensor I31, the distance sensor II32, the electric push rod 5 and the servo motor I13 are all electrically connected to the controller 33.

[0042] When the head end of the glass ribbon falls on the supporting block Ⅰ901, the distance sensor Ⅰ31 will sense that the distance between it and the glass ribbon is less than the preset value. At this time, the distance sensor Ⅰ31 sends a signal. After receiving the signal, the controller 33 will automatically control the servo motor Ⅰ13 to drive the screw rod 14 to rotate, so that the screw rod 14 drives the slide plate 4 to move to the right; when the distance sensor Ⅱ32 senses that the distance between it and the slide plate 4 is less than the preset value, the distance sensor Ⅱ32 will send a signal. After receiving the signal, the controller 33 will automatically control the servo motor Ⅰ13 to drive the screw rod 14 to rotate faster, so that the screw rod 14 drives the slide plate 4 to move to the right faster, and then the controller 33 will automatically control the electric push rod 5 to drive the rotating frame 6 and the roller 7 to move upward and reset; in this way, the controller 33 can be used to automatically control the servo motor Ⅰ13 and the electric push rod 5, so that manual control is not required, thereby simplifying manual operation.
