The embossed glass is also called patterned glass, and is widely applied to indoor partitions, door and window glass, bathroom glass partitions, solar power generation assembly protection cover plates and the like. And, some embossed glasses have higher strength than ordinary flat glass after hardening due to the embossing roller extrusion printing process, and belong to high-strength glass.
Because the surface of the embossed glass is uneven, the common polishing method has lower efficiency and poorer polishing effect.

The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.
Some embodiments of the application are described in detail. The following embodiments and features of the embodiments may be combined with each other without collision.
Examples
Referring to fig. 1-5, the present embodiment provides a glass processing apparatus 10, which can make a glass liquid S1 into a printed glass ribbon S3 with higher surface precision, and directly obtain a printed glass sheet S4 without surface polishing after cutting.
The glass processing apparatus 10 of the present embodiment includes a glass liquid containing chamber 11, a carrying table 12, a conveying roller group 13, a patterning roller group 14, and a polishing device 15.
The molten glass accommodating chamber 11 is for accommodating molten glass S1. The molten glass S1 may be prepared upstream, obtained by heating and melting raw materials in a desired ratio, and then added to the molten glass accommodating chamber 11. The molten glass accommodating chamber 11 has a molten glass outlet 16 for outflow of the molten glass S1.
The stage 12 is located downstream of the glass-accommodating chamber 11 and receives the glass S1 flowing out from the glass-flow outlet 16. The upper surface of the stage 12 is smooth to make the lower surface of the molten glass S1 flat. The carrier 12 has a vertically through opening 17 for the arrangement of the conveyor roller assembly 13. The table 12 may have a small angle (e.g., 0-10 deg.) downhill section 18 to facilitate the flow of molten glass S1.
The conveying roller set 13 is used for conveying the molten glass S1, and the conveying roller set 13 comprises a lower conveying roller 19 and an upper conveying roller 20; the upper conveying roller 20 and the lower conveying roller 19 are smooth rollers with cylindrical surfaces on the outer surfaces; the lower conveying rollers 19 are located above the lower conveying rollers 19 at intervals from below to above at positions corresponding to the through-holes 17, and are vertically spaced from the lower conveying rollers 19 to define a molten glass conveying passage. The lower conveying roller 19 and the upper conveying roller 20 rotate in opposite directions, and the molten glass S1 can be driven to flow downstream by the opposite rotation of the lower conveying roller and the upper conveying roller.
In this embodiment, the through opening 17 divides the carrying floor 12 into an upstream lip 43 and a downstream downhill section 18. The lip brick 43 may be in the shape of a lip brick in the prior art, for example, as shown in the drawing, one side of the lip brick 43 near the lower conveying roller 19 forms an extended tip, the tip extends to the top position of the outer cylindrical surface of the lower conveying roller 19, that is, one side surface of the lip brick 43 facing the lower conveying roller 19 is set to be a cambered surface with a radian close to the outer cylindrical surface of the lower conveying roller 19, and only a small gap (for example, less than 3 mm) exists between the cambered surface of the lip brick 43 and the lower conveying roller 19, and the glass liquid flowing to the top position of the outer cylindrical surface of the lower conveying roller 19 is driven to flow downstream when the lower conveying roller 19 rotates due to a certain viscosity of the glass liquid, so that the glass liquid cannot or is not easy to flow out from the gap between the lip brick 43 and the lower conveying roller 19. The embossing roll set 14 is disposed downstream of the conveying roll set 13 and is used for embossing the upper surface of the semi-solidified molten glass S2. The embossing roll set 14 comprises a lower press roll 21 and an embossing press roll 22, wherein the outer circumferential surface of the embossing press roll 22 is provided with an uneven embossing surface 23, the lower press roll 21 and the embossing press roll 22 are vertically arranged at intervals in a relative mode, and an embossing channel 24 is defined between the lower press roll 21 and the embossing press roll 22. The rotation directions of the lower press roller 21 and the printing press roller 22 are opposite, and the opposite rotation of the lower press roller and the printing press roller can drive the semi-solidified molten glass S2 to move downstream, and print on the upper surface of the semi-solidified molten glass S2.
The semi-solidified molten glass S2 is obtained by gradually cooling the molten glass S1 having a relatively high temperature and conveyed downstream by the conveying roller group 13. The semi-cured glass liquid S2 has reduced fluidity but is still not fully hardened, so that surface printing can be performed in roll form.
A first temperature control chamber 25 is further arranged between the conveying roller set 13 and the embossing roller set 14, and the first temperature control chamber 25 is used for controlling the temperature of the glass liquid S1 entering the embossing roller set 14 so as to control the state of the semi-solidified glass liquid S2 entering the embossing roller set 14, so that the embossing forming is facilitated.
A polishing device 15 is provided downstream of the embossing roll set 14 for polishing the upper surface of the glass ribbon S3 formed by embossing and hardening the semi-solidified molten glass S2.
In this embodiment, a second temperature control chamber 33 is further provided between the embossing roll set 14 and the polishing device 15, the second temperature control chamber 33 being used to control the hardening of the semi-solidified molten glass S2 and to control the temperature of the glass ribbon S3 entering the polishing device 15.
In this embodiment, the glass processing apparatus 10 further includes a cutting device 34, the cutting device 34 being disposed downstream of the polishing device 15 for cutting the glass ribbon S3 according to a set length to obtain a glass sheet S4 of a desired length.
Because the glass ribbon S3 is polished, the precision of the upper surface of each glass plate S4 obtained by cutting the glass ribbon S3 is in the condition of meeting the precision requirement after polishing, and the glass plates are not required to be polished respectively, so that the subsequent polishing time is saved.
In addition, the upper surface of the printed glass ribbon S3 is in an uneven state (such as the wavy surface shown in the embodiment), and the glass ribbon S3 continuously moves downstream along with the driving of the conveying roller set 13 and the printing roller set 14 in the continuous manufacturing process of the glass processing apparatus 10, and the uneven state of the upper surface thereof continuously and dynamically changes.
The polishing wheel and the like in the prior art can conveniently polish a plane, but are difficult to adapt to polishing of a printing surface with continuous dynamic change of a concave-convex state. The main reason is that the surface with continuously changed concave-convex state is difficult to be effectively pressed or the pressing force is difficult to be kept uniform by the polishing structure of the plane or smooth cylindrical surface of the existing polishing wheel, and further, the concave-convex surface is difficult to be effectively and uniformly polished, so that the polishing effect is poor.
The present embodiment provides a polishing apparatus 15 comprising a support pad 26, a polishing press roller 27, a flexible polishing belt 28, and a belt drive 29. The support pad 26 is used for bearing the glass ribbon S3 obtained by hardening after the output of the embossing roller set 14, and the polishing press roller 27 is used for pressing the flexible polishing belt 28 on the upper surface of the glass ribbon S3. The belt driving device 29 is in transmission connection with the flexible polishing belt 28 and is used for driving the flexible polishing belt 28 to slide on the upper surface of the glass belt S3 so as to polish the upper surface of the glass belt S3. Alternatively, the belt driving device 29 includes a belt driving motor 35, a driving pulley 36, and a plurality of supporting pulleys 37, where the belt driving motor 35 drives the driving pulley 36 to rotate, and further drives the flexible polishing belt 28 to rotate in a circulating manner, and each supporting pulley 37 is used for supporting the flexible polishing belt 28. In this embodiment, the driving pulley 36, the supporting pulley 37 and the grinding roller 27 are arranged in an isosceles triangle, so that the flexible grinding belt 28 is supported to approximate an isosceles triangle.
In other embodiments, the belt drive 29 for driving the flexible sanding belt 28 into motion to sand the glass ribbon may be provided in other forms, not limited herein.
Optionally, the polishing apparatus 15 further includes a polishing liquid supply tank 31 for containing glass polishing liquid; a polishing liquid supply groove 31 is provided on the moving path of the flexible polishing belt 28. The flexible polishing belt 28 is made of fine fiber cloth, flannelette or quartz cloth, and the flexible polishing belt 28 passes through the polishing liquid supply groove 31 and can absorb glass polishing liquid in the polishing liquid supply groove 31 to polish the upper surface of the glass belt S3.
Wherein the radius r1 of the polishing press roller 27 is equal to the radius r2 of the embossing press roller 22, the shape of the outer peripheral surface of the polishing press roller 27 is the same as the embossing surface 23 of the embossing press roller 22, and the rotation speed w1 of the polishing press roller 27, the rotation speed w2 of the embossing press roller 22, the moving speed v1 of the glass ribbon S3, and the linear speed v2 of the flexible polishing belt 28 satisfy the following formulas: v1=w1=r1=w2×r2, v2+.v1. The linear velocity v2 of the flexible polishing belt 28 is set to be larger as required, and the direction of the linear velocity of the flexible polishing belt 28 at the position pressed on the glass ribbon S3 is opposite to the moving direction of the glass ribbon S3, so that the moving velocity of the flexible polishing belt 28 relative to the glass ribbon S3 is the sum of absolute values of the linear velocities of the two, that is, the two have larger relative velocity, and the polishing efficiency and the polishing effect are improved.
The sanding roller 27 and the embossing roller 22 are driven by a synchronous belt assembly 30 so as to synchronously rotate at a constant speed. The synchronous belt assembly 30 may include two synchronous pulleys and a synchronous belt connecting the two synchronous belts, the printing press roller 22 is driven to rotate by a driving member (such as a rotating motor) to realize printing, and meanwhile, the printing press roller 22 drives the polishing press roller 27 to synchronously rotate through the synchronous belt assembly 30, so that the patterns on the periphery of the polishing press roller 27 also keep corresponding to the printed concave-convex patterns of the glass ribbon S3, and the flexible polishing belt 28 can be reliably, uniformly and stably pressed on the upper surface of the glass ribbon S3.
For example, as shown in fig. 4 and 5, the upper surface of the glass ribbon S3 in this embodiment is continuously concave-convex wavy, having the crest protrusions 38 and the trough recesses 39 arranged in sequence. The corresponding sanding roller 27 has a peripheral surface on which the crest convex portions 40 and the trough concave portions 41 are distributed in order. Since the moving speed v1 of the glass ribbon S3 is equal to the product of the rotating speed w1 of the polishing press roller 27 and the radius r1 of the polishing press roller 27, in this embodiment, only the trough notch 39 of the trough convex 40 of the polishing press roller 27 corresponding to the glass ribbon S3 and the trough concave 41 of the polishing press roller 27 corresponding to the trough convex 38 of the glass ribbon S3 in the initial state are required to be ensured, and thereafter, the polishing press roller 27 rotates at the rotating speed w1 while the glass ribbon S3 moves at the speed v1, so that the correspondence between the trough corresponding to the trough and the trough corresponding to the crest can be continuously maintained between the polishing press roller 27 and the glass ribbon S3, and the polishing press roller 27 can maintain a certain gap with the glass ribbon S3 towards the glass ribbon S3, and the flexible polishing belt 28 can be pressed on the glass ribbon S3 with uniform and stable pressure, so that the flexible polishing belt 28 can continuously polish the upper surface of the glass ribbon S3 continuously moving downstream, and polishing is continuously performed with high efficiency; the pressing force is stable, the polishing effect and consistency are good, and the higher surface precision and consistency of the polished glass ribbon S3 are ensured.
Optionally, the grinding device 15 further comprises an elastic support structure 32, the elastic support structure 32 abutting against the grinding press roller 27 for elastically pressing the grinding press roller 27 and the flexible grinding belt 28 down against the upper surface of the glass ribbon S3. The resilient support structure 32 may be configured with an adjustable resilient force to facilitate adjustment of the sharpening pressure.
Optionally, a plurality of support rollers 42 may be provided on the path of travel of the glass ribbon S3 to support the glass ribbon S3 and allow downstream movement of the glass ribbon S3.
To avoid excessive wear of the grinding rolls 27, the grinding rolls 27 may be made of a material having a relatively high hardness.
When the glass processing apparatus 10 of the present embodiment is used, the molten glass S1 is conveyed downstream through the glass conveying passage of the conveying roller group 13, and the temperature of the molten glass S1 gradually decreases at the time of conveyance to gradually turn into a semi-solidified molten glass S2; the pattern is stamped on the upper surface of the semi-solidified glass liquid S2 by the embossing press roller 22 when the semi-solidified glass liquid S2 passes through the embossing roller set 14, the semi-solidified glass liquid S2 after embossing is gradually cooled in the process of continuously conveying the semi-solidified glass liquid S2 to obtain a hardened glass belt S3, and the upper surface of the embossing of the glass belt S3 is polished by the polishing device 15 to obtain the glass belt S3 with the upper surface meeting the roughness requirement.
The glass processing apparatus 10 of the present embodiment can obtain a high-strength printed glass by the conveyance of the conveyance roller group 13 and the extrusion-printing conveyance of the printing roller group 14. After the printed glass is hardened and formed, the glass processing device 10 polishes the upper surface of the printed glass through the polishing device 15, and directly obtains the glass strip S3 with the surface quality meeting the use requirement.
In some prior art, a glass ribbon is obtained without polishing, then the glass ribbon is cut into small glass plates meeting the use requirement, and finally the surfaces of the glass plates are polished outside a glass forming assembly line according to the surface requirement. In this way, each glass plate needs to be polished separately, and each polishing needs to be performed with auxiliary operations such as repositioning, so that the polishing efficiency is low.
In the glass processing apparatus 10 of the present embodiment, after the molten glass S1 is formed into the glass ribbon S3, the glass ribbon S3 is polished immediately, so as to directly obtain the glass ribbon S3 having a surface with a desired accuracy. After the polished glass ribbon S3 is subsequently cut into glass sheet S4, no further polishing is required. Compared with the prior art, the centralized polishing mode has the advantage that the efficiency is remarkably improved when a plurality of cut glass plates S4 are polished respectively.
In addition, the polishing and grinding method of a conventional polishing wheel and the like is difficult to directly apply to the grinding of the rugged printing piece. Especially in the case of a relatively complex relief pattern. For example, the surface of the single-sided figure shown in the present embodiment is wavy, and it is difficult to effectively attach the surface with a polishing wheel, so that it is difficult to realize sanding and polishing with high efficiency and high accuracy.
In this embodiment, the polishing press roller 27 with the same shape of the outer peripheral surface and the printing surface of the printing press roller 22 is provided, so that the concave-convex state of the outer peripheral surface of the polishing press roller 27 is exactly equal to the concave-convex pattern of the upper surface of the glass strip S3 obtained by embossing by the printing press roller 22, and the polishing press roller 27 and the printing press roller 22 synchronously rotate, so that the polishing press roller 27 and the glass strip S3 can always keep the correspondence relationship between the wave crest corresponding to the wave trough and the wave trough corresponding to the wave crest in the relative motion, the flexible polishing belt 28 can be ensured to be pressed on the glass strip S3 by the polishing press roller 27 under uniform and stable pressure, and further, the flexible polishing belt 28 can continuously polish the upper surface of the glass strip S3 which continuously moves downstream, so that polishing is continuously performed with high efficiency; the pressing force is stable, the polishing effect and consistency are good, and the higher surface precision and consistency of the polished glass ribbon S3 are ensured.
For some embossed glass with higher strength after embossing patterns, the polishing method of pressing the flexible polishing belt 28 on the polishing surface by the polishing press roller 27 in the embodiment can also realize uniform polishing of the polishing surface, and has good polishing effect.
In other embodiments, flexible sanding belt 28 may also be a single-sided sandpaper with the sanded face of the single-sided sandpaper facing toward glass ribbon S3.
The present embodiment also provides a glass processing method based on the aforementioned glass processing apparatus 10, the glass processing method comprising the steps of:
supplying molten glass S1 melted into a liquid state into the glass liquid accommodating chamber 11, and the glass liquid S1 flows out to the stage 12 through the glass liquid outlet 16 and is conveyed downstream from the glass liquid conveying passage by the conveying roller group 13;
gradually cooling the molten glass S1 into semi-solidified molten glass S2 in the downstream conveying process, and embossing the semi-solidified molten glass S2 by the embossing roller set 14 to form an upper surface with embossing;
gradually cooling the half-cured glass liquid S2 after printing in the process of continuously conveying the half-cured glass liquid S2 to the downstream to obtain a hardened glass belt S3;
polishing device 15 polishes the upper surface of the conveyed glass ribbon S3 to obtain a glass ribbon S3 with the upper surface meeting the roughness requirement;
the cutting device 34 can cut the glass ribbon S3 to obtain a plurality of glass sheets S4 of a desired length.
The above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present application.
