[0034] Reference Figure 7 and Figure 8 As shown, the connection plate 701 is provided with a plurality of internal connection ports 702 corresponding to the external connection ports 202 .
[0035] Reference Figure 1 and Figure 2 As shown, the forming plate 6 is arranged at an end away from the connecting plate 701 and tilted downward, and the forming plate 6 includes a bottom axis edge 703, which is the bottom edge of the end of the forming plate 6 tilted downward, and the bottom axis edge 703 coincides with the connecting line of the lower right ends of the two baffles 7.
[0036] Reference Figure 6 and Figure 7 As shown, the arc groove 203 is arranged around the bottom axis edge 703 , and a plurality of external connection ports 202 are arranged around the bottom axis edge 703 at equal distances.
[0037] Further, see Figure 3 As shown, a heating assembly is arranged at the top of the baffle 7 , and the heating assembly includes a platinum sheet 10 arranged at the top of the baffle 7 , and a platinum electrode 11 is arranged at one end of the platinum sheet 10 away from the baffle 7 .
[0038] Further, see Figure 4 and Figure 5 As shown, the upper surface of the formed plate 6 is provided with corrugated grooves 13 .
[0039] Furthermore, the vertical plate 201 and the connecting plate 701 are fixed by bolts 204, and the bolts 204 pass through the external connecting port 202 and the internal connecting port 702. In an optional embodiment, the inner side surface of the external connecting port 202 is provided with threads, and the bolts 204 and the external connecting port 202 are threadedly connected. In another optional embodiment, the inner side surface of the internal connecting port 702 is provided with threads, and the bolts 204 and the internal connecting port 702 are threadedly connected.
[0040] Among them, it needs to be supplemented that the glass liquid 1 poured into the flow channel 2 forms a glass liquid supply flow 5 through the supply bowl 3 and the supply pipe 4, and the glass liquid supply flow 5 falls on the upper surface of the forming plate 6 to form a flattened area glass ribbon 8, and the flattened area glass ribbon 8 passes through the bottom axis edge 703 to form a formed glass ribbon 9, and the formed glass ribbon 9 is guided by the traction roller 12, wherein the traction roller 12 is used to pull the formed glass ribbon 9 away from the device. This is the prior art and will not be elaborated here.
[0041] The device utilizes the gravity of the glass liquid supply flow 5 itself through the arrangement and cooperation of the flow channel 2, the vertical plate 201 and the forming plate 6, so that it is automatically flattened on the top surface of the forming plate 6, and utilizes the wide design range of the width of the forming plate 6, so that the width of the formed glass ribbon 9 can be large, that is, the device can produce wide-width flexible glass, and can control the temperature of the forming plate 6 and the flattening area glass ribbon 8 thereon through the platinum electrode 11 and the platinum sheet 10 according to the actual thinning of the flattening area glass ribbon 8, thereby facilitating the improvement of the spreading speed of the flattening area glass ribbon 8 and the thickness of the flattening area glass ribbon 8. Uniformity can also be achieved by pushing up the connecting plate 701 so that the connecting plate 701 slides on the arc groove 203 and then fixing it with the bolt 204, thereby successfully realizing the quick and convenient adjustment of the inclination angle of the forming plate 6, thereby greatly improving the flexibility of the device, and the setting of the corrugated groove 13 forms an overflow effect on the top of the corrugated groove 13 during the thinning process of the flattening area glass strip 8 on the forming plate 6, thereby increasing the spreading speed of the flattening area glass strip 8 and stabilizing the thickness of the flattening area glass strip 8, further improving the forming quality of the glass liquid 1, and the structural setting is exquisite, efficient, and easy to operate.
[0042] The working principle of the device is now explained through its operation process: when using the device, it is first necessary to adjust the inclination angle of the forming plate 6, and the adjustment method is: by rotating the bolt 204, the bolt 204 and the external connection port 202 or the internal connection port 702 are disengaged. At this time, push the connecting plate 701 upward, and the connecting plate 701 will slide on the arc groove 203. Since the arc groove 203, the external connection port 202 and the internal connection port 702 are all arranged around the bottom axis edge 703, when the inclination angle of the forming plate 6 reaches the set value, the external connection port 202 will correspond to the internal connection port 702. At this time, the inclination angle of the forming plate 6 can be fixed by threading the rotating bolt 204 with the external connection port 202 or the internal connection port 702, and the operation is convenient and efficient.
[0043] The glass liquid 1 is poured into the flow channel 2, and the glass liquid 1 will form a glass liquid supply flow 5 through the supply bowl 3 and the supply pipe 4. The glass liquid supply flow 5 will fall on the forming plate 6 and be flattened under the action of its gravity, and then thinned into a flattening area glass ribbon 8. At this time, according to the actual thinning situation of the flattening area glass ribbon 8, the temperature of the baffle 7, the forming plate 6 and the flattening area glass ribbon 8 thinned thereon can be controlled by the platinum electrode 11 and the platinum sheet 10, which is beneficial to improve the spreading speed of the flattening area glass ribbon 8 and the thickness uniformity of the flattening area glass ribbon 8. At the same time, according to the actual spreading speed and thickness uniformity of the flattening area glass ribbon 8, the inclination angle of the forming plate 6 can be adaptively adjusted through the above-mentioned adjustment method of the inclination angle of the forming plate 6. When the inclination angle of the forming plate 6 is larger, that is, under the action of gravity, the speed at which the flattening area glass ribbon 8 is thinned downward on the forming plate 6 will be faster, which greatly improves the flexibility of the device.
[0044] It should be noted that the heating function of the platinum electrode 11 and the platinum sheet 10 is a prior art and will not be described in detail here.
[0045] It should be noted that the arrangement of the corrugated groove 13 allows an overflow effect to be formed at the top of the corrugated groove 13 during the thinning process of the glass ribbon 8 in the flattening area on the forming plate 6, thereby increasing the spreading speed of the glass ribbon 8 in the flattening area and stabilizing the thickness of the glass ribbon 8 in the flattening area, and further improving the quality of the formed glass ribbon 9 formed after the glass ribbon 8 in the flattening area passes through the bottom axis edge 703, thereby greatly improving the forming quality of the glass liquid 1, and the structural arrangement is sophisticated, efficient, and easy to operate.
[0046] It should be noted that when the device is not in use, the user can remove it by rotating the bolt 204, then invert the baffle 7, and make the baffle 7 pass through the through-hole opened on the vertical plate 201, and then store the device. The setting of the through-hole not only makes the device not take up a large space when stored, but also facilitates storage. At the same time, since the top surface of the forming plate 6 is set downward, the top surface of the forming plate 6 is not easily contacted with dust, thereby keeping the top surface of the forming plate 6 clean, which is convenient for the next use of the device.
[0047] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
