[0034] Here’s how it works:

[0035] When the AG glass etching device is to be used, the glass can be placed on the upper front end of the conveyor body 2 in operation, so that the glass can be transported backward. When the glass is transported to the lower end of the wax spraying assembly 3, the pump body 33 provided inside the wax spraying assembly 3 can transport the paraffin stored in the storage box 32 to the nozzle 34 connected to the bottom, so that the nozzle 34 can spray the paraffin evenly on the outside of the glass. After the paraffin spraying is completed, the glass will be moved into the drying chamber 4 to achieve the drying activity. Before entering, the glass will contact with the scraper 6 provided on the front side of the drying chamber 4 to scrape the sprayed paraffin on the glass, so that the upper end of the glass is evenly coated with paraffin. Secondly, the upper end of the scraper 6 can be used to The first cylinder 5 provided in the middle is used to adjust the height of the scraper 6 to meet the requirements of using glass of different thicknesses. The glass that has been scraped flat by paraffin wax can enter the drying chamber 4 to complete the drying activity. Then, when the glass is transmitted to the lower end of the connecting frame 7, the motor 8, the first screw 9 and the second cylinder 10 cooperate to drive the corresponding engraving knife 11 connected to the bottom of the second cylinder 10, so that the engraving knife 11 can move forward and backward or up and down to perform pattern engraving activities on the paraffin wax on the glass. After the engraving activity is completed, the glass will be transmitted to the lower end of the hydrofluoric acid component 12 for spraying of hydrofluoric acid liquid, so that the hydrofluoric acid liquid is evenly sprayed to the outer side of the upper end of the glass, thereby completing the fully automatic etching activity of AG glass;

[0036] In order to ensure that the top etching surface of the glass can be kept clean when it is placed on the upper end of the conveyor body 2 for full-automatic etching, the glass to be etched can be placed in advance inside the receiving frame 131 to contact the conveying roller 132 and the cleaning roller 133 installed inside the receiving frame 131, and the conveying roller 132 can realize rotation through the servo motor 134 connected to the right side, so that the glass between the conveying roller 132 and the cleaning roller 133 can be conveyed toward the conveyor body 2, thereby, the cleaning roller 133 as a whole can realize rolling cleaning of the etching surface on the upper end of the glass to reduce dust adhesion;

[0037] In order to enhance the functionality of the cleaning roller 133, an adjustment component 135 is provided at the upper end of the receiving frame 131 to meet the requirements of fine adjustment up and down to meet the requirements of cleaning glass of different sizes. That is, when adjustment is required, the second screw 1354 rotatably connected to the middle of the adjustment frame 1353 can be rotated to enable the second screw 1354 to realize the upward transmission of the connecting strip 1352 threadedly connected at the bottom. As the connecting strip 1352 moves up and down, the connecting clamps 1351 symmetrically fastened to the left and right sides of the connecting strip 1352 can be moved up synchronously, so that the cleaning roller 133 installed between the connecting clamps 1351 on both sides can be conveniently adjusted upward to meet the requirements of cleaning glass of different sizes.

[0038] If the cleaning roller 133 needs to be replaced as a whole after one end is used, the bolt 1356 screwed into the upper end of the right connecting clamp 1351 can be unscrewed to release the locking state of the fastening strip 1355 on the right end of the cleaning roller 133. Thus, the cleaning roller 133 can be taken out from between the connecting clamps 1351 on both sides, realizing convenient replacement.

[0039] Secondly, the support assembly 136 installed at the lower end of the receiving frame 131 can assist in the support coordination before and after the glass is cleaned through the two groups of support blocks 1367 arranged on the left and right sides, so that the glass conduction cleaning process is stable. If it is necessary to adjust the support spacing between the two groups of support blocks 1367, the transmission motor 1361 arranged at the lower end of the receiving frame 131 can be driven to make the transmission motor 1361 realize the rotation of the driving wheel 1362 connected to the top. As the driving wheel 1362 rotates, the belt 1363 connected to the outside of the driving wheel 1362 can be driven to realize the rotation of the driving wheel 1362. Now, driven by the driven wheel 1364 connected on the right side, the belt 1363 correspondingly connected to the front and rear ends of the belt 1363 will realize the pulling of the corresponding externally connected moving frame 1366, so that the moving frames 1366 on both sides can achieve relative transverse movement. In this way, the supporting blocks 1367 correspondingly installed on the upper ends of the moving frames 1366 on both sides can achieve relative transverse movement along the support rod 1368 laterally inserted in the middle, and the supporting distance between the two groups of supporting blocks 1367 can be conveniently adjusted to meet the auxiliary support use of glass of different sizes, thereby achieving the advantage of flexible and adjustable supporting cooperation for glass.

[0040] The utility model provides an AG glass etching device, which is provided with a cleaning transmission device 13, that is, under the cooperation of a transmission roller 132 and a cleaning roller 133, auxiliary transmission cleaning of the glass can be achieved, and dust adhesion can be reduced. The second screw 1354 and the connecting strip 1352 provided inside the adjusting component 135 are used to indirectly drive the connecting clamps 1351 on both sides, so that the cleaning roller 133 is lifted accordingly, and the height can be conveniently adjusted, thereby achieving the advantage of adjustable cleaning of the glass etching surface, and a supporting component 136 is provided, that is, the auxiliary support before and after the glass is cleaned can be achieved through the supporting blocks 1367 provided on the left and right, and under the transmission of the driving wheel 1362, the belt 1363 and the driven wheel 1364, the connecting arms 1365 provided on both sides can pull the moving frame 1366 correspondingly, so as to conveniently change the distance between the two groups of supporting blocks 1367, and realize the flexible adjustment of the supporting distance, thereby achieving the advantage of flexible and adjustable supporting cooperation of the glass.
