Description

Technical Field

[0001] This invention relates to the field of glass production, and more particularly to a frosted waterjet. Background Technology

[0002] As a means of transportation, automobiles are the most commonly used mode of transport. In-vehicle glass visual screens, as an important component of the car interior, are a focus for car buyers. With more and more automakers prioritizing the development of autonomous driving technology, the number and size of in-vehicle visual screens are increasing. However, in-vehicle glass screens can cause severe glare, which can potentially lead to accidents. Therefore, anti-glare technology for in-vehicle glass has become a growing concern for automakers. This has led to the development of AG (Agglomerate Grating) treatment, which uses a frosting solution to "roughen" the glass surface, transforming the reflective surface from a smooth mirror to a non-reflective matte surface.

[0003] Currently, the trend of AG glass in automotive manufacturing is increasing, but there are very few domestic manufacturers capable of processing AG glass that meets the requirements. Waterjet frosting is an extremely critical component in AG glass processing equipment, and the coating effect of waterjet frosting plays a vital role in the preparation of AG glass. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a sandblasting waterjet with a simple structure and better coating effect.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A sandblasting waterjet includes a waterjet cutting edge, which is fixedly connected to a waterjet frame. The waterjet frame is a hollow column with an open top and front end. An inlet pipe is fixedly connected to the rear side of the top of the waterjet frame, and an outlet hole is provided on the side of the inlet pipe. A front overflow plate and a rear overflow plate are fixedly connected to the middle of the bottom of the waterjet frame. Both ends of the front and rear overflow plates are in contact with the inner walls of both sides of the waterjet frame. The front overflow plate is located at the front end of the rear overflow plate, and a gap is provided between the two. A plurality of buffer through holes are provided on the rear overflow plate, and the plurality of buffer through holes are arranged in a matrix. The waterjet cutting edge is fixedly connected to the front side of the bottom of the waterjet frame. A flow limit regulator is provided at the front end of the waterjet cutting edge. The flow limit regulator is connected to both sides of the waterjet frame, and a gap is provided between the flow limit regulator and the waterjet cutting edge.

[0007] Furthermore, the water jet holder includes a base plate, a left side plate, a right side plate, and a rear side plate; the left side plate and the right side plate are respectively fixedly connected to the left and right sides of the base plate, and the rear side plate is fixedly connected to the rear end of the base plate and is fixedly connected to the rear ends of the left side plate and the right side plate.

[0008] Furthermore, the left side plate, right side plate, and rear side plate are all welded to the bottom plate, and the rear ends of the left side plate and right side plate are all welded to the front end of the rear side plate; the front overflow plate, rear overflow plate, and bottom end of the water jet blade are all welded to the bottom plate.

[0009] Furthermore, both the left and right side plates are equipped with height adjusters. The height adjusters are L-shaped and have elongated through holes, which are then bolted to the left and right side plates.

[0010] Furthermore, the inlet pipe is a 1.53-inch PP round pipe, with one end sealed and the other end open, penetrating the side wall of the water jet holder for injection of sanding liquid.

[0011] Furthermore, the outlet holes are arranged in a row on the side of the inlet pipe, and the diameter of the outlet holes is 12mm; the distance between adjacent outlet holes is 5-30mm.

[0012] Furthermore, both the front overflow plate and the rear overflow plate are made of PP board with a thickness of not less than 10mm. The height of the front overflow plate is 20-30mm, and the diameter of the buffer through hole on the rear overflow plate is 12mm. The distance between adjacent buffer through holes in the lateral direction is 10-15mm, and the distance between adjacent buffer through holes in the longitudinal direction is 50-100mm.

[0013] Furthermore, the waterjet cutting edge is engraved from a 20mm thick P-plate, and its surface roughness is within 20nm.

[0014] Furthermore, both ends of the flow limiting regulator are provided with slots, which are engaged with the two sides of the water jet holder body.

[0015] Furthermore, the flow limiting regulator includes a support plate and a fixed baffle. The support plate has slots at both ends, and the fixed baffle is fixedly connected to the rear end of the support plate. The width direction of the fixed baffle is perpendicular to the width direction of the support plate. The fixed baffle is set on the upper side of the front end of the water jet nozzle and has a gap between it and the water jet nozzle. The front end cross-section of the water jet nozzle is a downwardly curved arc.

[0016] Compared with the prior art, the advantages and positive effects of this invention are:

[0017] This invention employs a design with multiple outlet holes in the inlet pipe, allowing the frosting solution to enter the waterjet holder uniformly and slowly. Simultaneously, the flow of the frosting solution is further slowed by the front and rear overflow plates. Finally, by adjusting the distance between the flow limiter and the waterjet blade, the width of the water curtain can be effectively controlled, ensuring the frosting solution is evenly and slowly applied to the glass surface, effectively improving the AG coating effect. Furthermore, by setting several buffer through-holes in a matrix arrangement on the rear overflow plate, the flow of the frosting solution is balanced, resulting in a more uniform and smooth flow. Moreover, the distance between the flow limiter and the waterjet blade can be controlled by adjusting the installation position of the flow limiter, further enhancing the effectiveness of this invention.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present invention.

[0024] like Figures 1 to 4As shown, the sandblasting waterjet in this embodiment includes a waterjet cutting edge 10, which is fixedly connected to the waterjet frame. The waterjet frame includes a base plate 1, a left side plate 3, a right side plate 4, and a rear side plate 2. The left side plate 3 and the right side plate 4 are respectively welded to the left and right sides of the base plate 1, and the rear side plate 2 is welded to the rear end of the base plate 1 and welded to the rear ends of the left and right side plates 4.

[0025] The inlet pipe 5 is fixedly connected to the rear top of the water jet holder. The inlet pipe 5 is a 1.53-inch PP round pipe. If the pipe diameter is too small, the flow rate will be insufficient; if the pipe diameter is too large, the liquid output from each outlet hole 501 will be uneven. The inlet pipe 5 is fixedly welded to the left and right side plates 4. The right end of the inlet pipe 5 is sealed, and the left end is open and passes through the left side plate 3 for the injection of frosting liquid. The inlet pipe 5 has outlet holes 501 on its side. The outlet holes 501 are arranged in a row on the side of the inlet pipe 5, and the diameter of the outlet holes 501 is 12mm. The distance between adjacent outlet holes 501 is 5-30mm. If the hole diameter is too large or the hole spacing is too small, the liquid output from each outlet hole 501 will be uneven, and there will be less solution in places far from the inlet. If the hole diameter is too small or the hole spacing is too large, the flow rate of the frosting liquid will be insufficient for normal operation.

[0026] A front overflow plate 7 and a rear overflow plate 6 are welded to the middle of the base plate 1. Both the front overflow plate 7 and the rear overflow plate 6 are rectangular plates and perpendicular to the base plate 1. Their length direction is consistent with the length direction of the rear side plate 2. Both ends of the front overflow plate 7 and the rear overflow plate 6 are welded to the inner walls of the left side plate 3 and the right side plate 4. The front overflow plate 7 is located at the front end of the rear overflow plate 6, and there is a gap between the two. Both the front overflow plate 7 and the rear overflow plate 6 are made of PP plate with a thickness of 10mm. PP plates with a thickness of less than 10mm are prone to deformation after long-term use, affecting the performance. The height of the front overflow plate 7 is 20-30mm. If the height is too low, it will not have a buffering effect; if the height is too high, the drop will be too large, and the solution will be accelerated or even splashed after passing through the overflow plate, resulting in poor buffering effect. The rear overflow plate 6 is provided with several buffers. The through-hole 601 has a diameter of 12mm. Several buffer through-holes 601 are arranged in a matrix. In the matrix of buffer through-holes 601, the distance between adjacent buffer through-holes 601 laterally is 10-15mm, and the distance between adjacent buffer through-holes 601 longitudinally is 50-100mm. Since the frosting liquid has a certain viscosity and high solution tension, if the diameter of the buffer through-hole 601 is too small, the solution will not flow out easily. If the diameter of the buffer through-hole 601 is too large, it will not have a buffering effect. If the longitudinal or lateral spacing of adjacent buffer through-holes 601 is too small, the solution will easily pass through the overflow plate quickly and will not effectively buffer. If the longitudinal or lateral spacing of the holes is too large, the solution will have difficulty passing through the overflow plate, which will result in insufficient flow of frosting liquid for normal operation.

[0027] A waterjet nozzle 10 is welded to the front side of the bottom end of the waterjet holder. The waterjet nozzle 10 is rectangular and its length direction is consistent with the length direction of the rear plate 2. The waterjet nozzle 10 is engraved from a 20mm thick P plate with a surface roughness of less than 20nm. If the surface roughness is too large, the flow rate of the solution after passing through the waterjet nozzle 10 will not be uniform, and in severe cases, it may even cause bifurcation. A circular arc groove is provided on the lower side of the front end of the waterjet nozzle 10. The cross-section of the front end of the waterjet nozzle 10 is a downward curved arc, which allows the solution to flow out more smoothly.

[0028] A flow limiter 9 is provided at the front end of the water jet cutter 10. The flow limiter 9 includes a support plate 902 and a fixed baffle 901. Both the support plate 902 and the fixed baffle 901 are rectangular plates that are consistent with the length direction of the water jet cutter 10. The fixed baffle 901 is fixedly connected to the rear end of the support plate 902. The width direction of the fixed baffle 901 is perpendicular to the width direction of the support plate 902. The fixed baffle 901 is located on the upper side of the front end of the water jet cutter 10 and has a gap with the water jet cutter 10. The fixed baffle 901 can prevent the sandblasting liquid from flowing over the upper end of the support plate 902 when the flow rate is large, thus failing to achieve the flow limit effect. The support plate 902 has slots 903 at both ends, which are engaged with the left side plate 3 and the right side plate 4. The support plate 902 has adjusting through holes 904 on both sides for fixing and adjusting the gap between the water jet cutter 10 and the fixed baffle 901. During installation, the adjustment through holes 904 at both ends of the support plate 902 are adjustablely connected to the fixing seats 11 located on the outer side of the bottom end of the left and right side plates by bolts. The fixing seats 11 are fixedly connected to the left and right side plates. By adjusting the fixed position of the adjustment through holes 904, the distance between the flow limit regulator 9 and the water jet blade 10 can be controlled, thereby realizing the control of the gap distance between the two.

[0029] Height adjusters 8 are provided on both the left side plate 3 and the right side plate 4. The height adjusters 8 are L-shaped, and their upper ends are provided with elongated through holes 801, which are then bolted to the left and right side plates 4. During installation, the bottom end of the height adjuster 8 is fixedly connected to the base (not shown, but it can also be fixed to other equipment), and the upper end of the height adjuster 8 can be adjusted to the left side plate 3 and the right side plate 4 through the elongated through holes 801. By adjusting the fixed position of the elongated through holes 801, the height of the water jet frame can be controlled, thereby adjusting the height of the water jet blade 10 and improving the effectiveness of the invention.

[0030] This invention employs a design with multiple outlet holes in the inlet pipe, allowing the frosting solution to enter the waterjet holder uniformly and slowly. Simultaneously, the flow of the frosting solution is further slowed by the front and rear overflow plates. Finally, by adjusting the distance between the flow limiter and the waterjet blade, the width of the water curtain can be effectively controlled, ensuring the frosting solution is evenly and slowly applied to the glass surface, effectively improving the AG coating effect. Furthermore, by setting several buffer through-holes in a matrix arrangement on the rear overflow plate, the flow of the frosting solution is balanced, resulting in a more uniform and smooth flow. Moreover, the distance between the flow limiter and the waterjet blade can be controlled by adjusting the installation position of the flow limiter, further enhancing the effectiveness of this invention.
