Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass etching, and specifically to a glass etching device. Background Technology
[0002] Etching is a glass processing technique primarily used to treat glass surfaces, creating patterns, text, or frosted effects. Sandblasting is a type of etching that uses a frosting solution to achieve this effect. Traditional sandblasting devices spray the frosting solution onto the glass surface, but the solution cannot be evenly distributed across all areas, resulting in uneven frosting and a less aesthetically pleasing finish.
[0003] Later, a type of sandblasting water jet with improved residue removal, as disclosed in patent number CN217323883U, appeared. It consists of an inlet pipe, a base plate, end plates connected to both ends of the base plate, and a back plate connected to one side of the base plate. The two ends of the back plate are connected to the two end plates respectively. A first overflow plate, a second overflow plate, and a third overflow plate are vertically arranged between the two end plates. The first overflow plate is located between the second overflow plate and the back plate. The first overflow plate has an overflow hole. The height of the top of the end plate, the top of the second overflow plate, and the top of the third overflow plate decreases sequentially. The side of the third overflow plate away from the second overflow plate is arc-shaped, and the bottom of the side of the third overflow plate away from the second overflow plate is connected to the edge of the base plate. The outlet end of the inlet pipe is located between the first overflow plate and the back plate.
[0004] In the aforementioned waterjet frosting process, the frosting solution enters the equipment and passes through the first and second overflow plates sequentially, finally flowing down from the third overflow plate to form a water curtain. The water curtain is more stable due to the obstruction and limiting effect of the three overflow plates, allowing for more uniform frosting as the glass passes through it at a constant speed. However, in actual use, because the frosting solution mainly consists of supersaturated aqueous solutions of etchants such as hydrofluoric acid, grain-forming agents such as sodium sulfate, and suspending agents such as starch and glycerin, sedimentation occurs over prolonged use. Therefore, when using the aforementioned equipment, sedimentation occurs between the first and second overflow plates, and between the second and third overflow plates. This causes the frosting solution that crosses the second and third overflow plates to become thinner, resulting in a poorer frosting effect. Utility Model Content
[0005] The present invention aims to provide a glass etching device to solve the problem of the outflowing frosting solution becoming thinner and the frosting effect becoming worse.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass etching device, including a frosting unit and a conveying unit. The frosting unit includes a water tank, a baffle, and an overflow plate. The baffle is vertically fixed in the water tank, dividing the water tank into an inlet tank and an outlet tank. The lower part of the baffle is provided with several overflow holes, all of which are distributed sequentially along the width direction of the overflow plate. An inlet pipe is provided in the inlet tank, and an outlet for introducing the frosting liquid into the water tank is provided on the inlet pipe. A notch is provided on the side wall of the outlet tank, and the overflow plate is inclinedly set at the notch. The upper end of the overflow plate extends into the outlet tank and is fixed with a guide plate. The guide plate and the overflow plate have a smooth transition, and the top of the guide plate is higher than the overflow hole.
[0007] The conveying unit is located below the overflow plate. The conveying unit includes a power unit and several conveying components distributed sequentially along the thickness direction of the overflow plate. The conveying components include conveying rollers, which are inclined with one end higher than the other end. The power unit is used to drive the conveying rollers to rotate.
[0008] The beneficial effects of this plan are:
[0009] 1. The frosting solution contains etching agents such as hydrofluoric acid. Large leaks can damage external equipment, base plates, and other devices and facilities. In this design, the conveyor rollers are tilted, so the glass being conveyed is also tilted with one end higher than the other. When the frosting solution falls onto the glass, it automatically flows down the tilted glass, preventing it from remaining on the glass and entering the next process, thus avoiding leakage of the frosting solution outside the frosting process.
[0010] 2. The baffle in this design has an overflow hole at the bottom. When the frosting liquid in the inlet tank overflows the overflow hole, it will flow into the outlet tank from the overflow hole. Compared with the current design where the frosting liquid overflows the baffle and flows from the top of the baffle to the outlet tank, the overflow hole in this design is located at the bottom of the baffle. With the same baffle height, the overflow hole design allows the frosting liquid at a lower position to flow out. Even if the frosting liquid settles in the inlet tank, the sediment can flow from the overflow hole to the outlet tank. During this process, since the frosting liquid is in a flowing state, the sediment will dissolve back into the frosting liquid, preventing the frosting liquid from becoming thinner and thus maintaining a better frosting effect.
[0011] Compared to setting a strip-shaped opening below the baffle, the design of several overflow holes in this scheme can reduce the space for the frosting liquid to pass through the baffle, improve the baffle's blocking effect on the frosting liquid, and thus better buffer the frosting liquid, making the flow of the frosting liquid in the outlet tank more stable. The liquid surface of the frosting liquid in the outlet tank will not fluctuate, so the frosting liquid on the overflow plate flows downward evenly, and the frosting effect of all parts of the glass is more uniform.
[0012] 3. This design incorporates a guide plate. Because the guide plate is higher than the overflow hole, the level of the frosting solution in the tank is also higher than the overflow hole. The frosting solution entering the outlet tank from the overflow hole is less likely to form ripples on the surface, resulting in a uniform thickness of the frosting solution flowing out from all positions on the overflow plate. Secondly, the guide plate guides the outflowing frosting solution, allowing it to flow more smoothly and evenly onto the overflow plate, further promoting uniform outflow. Finally, because only one overflow plate is used, the frosting device in this design is narrower and occupies less space.
[0013] Furthermore, the gap between adjacent overflow holes is 1.5~3cm.
[0014] Furthermore, the diameter of the overflow hole is 0.7~1.5cm.
[0015] Furthermore, the distance between the overflow hole and the bottom of the baffle is 1.5~3cm.
[0016] The beneficial effects of this solution are as follows: After actual testing, the design of this solution allows the baffle to maintain a good shielding and buffering effect on the sanding liquid in the water inlet tank, while the overflow hole can also provide enough space for the sanding liquid to flow out along the overflow plate, making the flow of sanding liquid on the overflow plate more stable and uniform.
[0017] Furthermore, the conveying assembly also includes several rubber rings, which are distributed sequentially along the axial direction of the conveying roller.
[0018] The beneficial effects of this solution are: the rubber ring is used to increase the maximum static friction of the glass on the conveyor roller, further ensuring that the glass will not slip along the axial direction of the conveyor roller when it is conveyed on the inclined conveyor roller, thereby better conveying the glass.
[0019] Furthermore, the conveying unit also includes a carrier plate, which is located on the conveying assembly and can be conveyed by the conveying assembly. The top of the carrier plate is provided with an adhesive layer.
[0020] The beneficial effects of this solution are as follows: when processing thin glass with a thickness of 0.3~0.7mm, the glass is mounted on a carrier plate and fixed by an adhesive layer. At this time, the carrier plate can fix and support the glass, preventing the glass from breaking when the frosting liquid impacts the glass, thereby improving the pass rate.
[0021] Furthermore, a limit bar is fixed to the bottom of the carrier plate, and the limit bar extends along the forward direction of the carrier plate.
[0022] The beneficial effects of this solution are: the limiting strip and the rubber ring are opposite each other, and the two work together to increase the limiting effect on the carrier plate and further prevent the carrier plate from slipping axially.
[0023] Furthermore, the bottom of the limit stop bar is in contact with the surface of the conveyor roller.
[0024] The beneficial effects of this solution are: the limiting stop strip can also increase the maximum static friction between the carrier plate and the conveyor roller, preventing the carrier plate from sliding along the axial direction of the conveyor roller.
[0025] Furthermore, the conveyor roller includes a shaft, a sleeve, and two end seals. The inner diameter of the sleeve is larger than the diameter of the shaft. The sleeve is fitted onto the shaft, and a support block is fixed on the shaft to abut against the inner wall of the sleeve. The two end seals are installed at the ends of the sleeve near both ends of the shaft to seal the sleeve.
[0026] The beneficial effects of this solution are: the cavity between the sleeve and the shaft in this solution results in a lighter conveyor roller, requires less energy to drive the conveyor roller to rotate, and is more energy-efficient.
[0027] Furthermore, there are several sleeves, and adjacent sleeves can be detachably connected.
[0028] The beneficial effects of this solution are: since the sleeves can be disassembled, any damaged sleeve can be replaced individually, thereby reducing maintenance costs. Attached Figure Description

[0033] The following detailed description illustrates the specific implementation method:
[0034] The reference numerals in the accompanying drawings include: water tank 1, liquid outlet tank 11, liquid inlet tank 12, water inlet pipe 2, water outlet 21, baffle 3, overflow hole 31, overflow plate 4, side plate 41, guide plate 5, frame 6, sleeve 7, rubber ring 71, end seal 72, shaft 8, support block 81, carrier plate 9, and limit stop bar 91.
[0035] Example
[0036] The implementation examples are basically as follows Figure 1 and Figure 2As shown, the glass etching equipment includes a frosting unit and a conveying unit. The frosting unit includes a water tank 1, an overflow plate 4, and a baffle 3. The baffle 3 is vertically disposed in the water tank 1 and fixed to the side wall of the water tank 1, dividing the water tank 1 into an inlet tank 12 on the right and an outlet tank 11 on the left. The lower part of the baffle 3 is provided with a plurality of overflow holes 31 along the width direction of the water tank 1. In this embodiment, the diameter of the overflow hole 31 is 1cm, the distance between adjacent overflow holes 31 is also 1cm, and the distance between the bottom of the overflow hole 31 and the lower end of the baffle 3 is 2cm.
[0037] Four inlet pipes are provided in the inlet tank 12 along its width, and multiple outlets 21 are provided on the inlet pipes along their length. All outlets 21 are distributed on the front and rear sides of the inlet pipes, which promotes the flow of frosting liquid in the tank 1 and reduces sedimentation. The right end of the inlet pipe penetrates the rear side wall of the tank 1 and extends to the outside of the tank 1.
[0038] The left side wall of the outlet tank 11 has a notch, and the overflow plate 4 is located at the notch. The lower surface of the overflow plate 4 abuts against the notch to prevent the frosting liquid from flowing out between the lower surface of the overflow plate 4 and the left side wall of the outlet tank 11. In this embodiment, the overflow plate 4 is inclined with the left end lower than the right end, and the angle between the overflow plate 4 and the bottom of the water tank 1 is 45°. The lower end of the overflow plate 4 extends to the bottom of the water tank 1, and at the lower end of the overflow plate 4, the lower surface of the overflow plate 4 is inclined towards the side closer to the upper surface, forming a "<" shape with the thickness gradually decreasing from right to left. That is, the lower end of the overflow plate 4 is the edge where the upper and lower surfaces intersect.
[0039] Two side plates 41 are integrally fixed to the upper surface of the overflow plate 4. The side plates 41 are located on both sides of the overflow plate 4 and are used to limit the frosting liquid on the overflow plate 4 to prevent the frosting liquid from leaking from the front and rear sides of the overflow plate 4. A guide plate 5 is integrally formed at the upper end of the overflow plate 4. The guide plate 5 is horizontally set and the top of the guide plate 5 is slightly higher than the overflow hole 31, so that the liquid level of the frosting liquid in the liquid outlet tank 11 can be higher than the overflow hole 31. The upper surfaces of the guide plate 5 and the overflow plate 4 are smoothly transitioned.
[0040] The conveying unit is located below the overflow plate 4. The conveying unit includes a power unit, several carrier plates 9, several rubber rings 71, and several conveying components, which are distributed sequentially from left to right. Each conveying component includes a conveying roller, which comprises a shaft 8, several sleeves 7, and two end seals 72. A frame 6 is located below the overflow plate 4. Both ends of the shaft 8 are connected to the frame 6 via bearings. Figure 3 and Figure 4In this embodiment, the shaft 8 is inclined with the left end higher than the right end. Multiple support blocks 81 are integrally formed along the axial direction on the shaft 8. The radial cross-section of each support block 81 is circular, and the diameter of the middle part of the support block 81 is smaller than the diameters of the left and right ends. A rubber ring 71 is fitted onto the middle part of the support block 81, and a sleeve 7 is fitted onto the shaft 8. The sleeves 7 and rubber rings 71 are spaced apart, meaning a sleeve 7 is placed between adjacent rubber rings 71. The left and right ends of the support block 81 are respectively engaged with two adjacent sleeves 7. The outer diameter of the rubber ring 71 is slightly larger than the outer diameter of the sleeve 7, and the end of the sleeve 7 abuts against the rubber ring 71, thus sealing the adjacent sleeves 7 through the rubber ring 71. Two end seals 72 are located at the left and right ends of the shaft body 8 respectively and are threaded to the shaft body 8. The end seals 72 are engaged with the end of the sleeve 7 closest to the end of the shaft body 8 to seal the end of the sleeve 7 and to position the sleeve 7 to prevent the sleeve 7 from moving along the axial direction of the shaft body 8.
[0041] The power component is an electric motor. The output shaft of the electric motor is connected to a power shaft via a coupling. The power shaft extends along the conveying direction of the conveyor roller and is equipped with several bevel gears. Each bevel gear corresponds to a shaft body 8. Another bevel gear is installed at the end of the shaft body 8. The power shaft drives the shaft body 8 to rotate through the cooperating bevel gear.
[0042] Several carrier plates 9 are placed on the conveyor roller. The top of the carrier plate 9 is provided with an adhesive layer, which is formed by coating the top of the carrier plate 9 with transparent glue in actual implementation. The bottom of the carrier plate 9 is engaged with a limiting strip 91. The limiting strip 91 extends along the conveying direction of the carrier plate 9 on the conveyor roller. When the carrier plate 9 is placed on the conveyor roller, the limiting strip 91 is in contact with the sleeve 7 to prevent the carrier plate 9 from sliding along the axial direction of the conveyor roller.
[0043] The specific implementation process is as follows:
[0044] During etching, if the glass to be processed is thicker than 0.7mm, it is placed directly on the conveyor roller for conveying. When the glass is thin glass with a thickness of 0.3~0.7mm, it is placed on the carrier plate 9 and supported by the carrier plate 9. At this time, the adhesive layer fixes the glass.
[0045] During the frosting process, the frosting solution enters the inlet tank 12 through the inlet pipe. As more frosting solution enters, the liquid level in the inlet tank 12 gradually rises. Finally, the frosting solution flows through the overflow hole 31 into the outlet tank 11. When the liquid level in the outlet tank 11 is higher than the top of the guide plate 5, the frosting solution in the outlet tank 11 flows out through the guide plate 5 and flows downward along the overflow plate 4, forming a water curtain below the overflow plate 4. The glass passes under the overflow plate 4 and through the water curtain under the action of the conveyor roller. Because the conveyor roller is tilted, the carrier plate 9 on the conveyor roller and the glass are also tilted. The frosting solution on the glass automatically flows down from the glass under the action of gravity without leaving a large amount of residue on the glass.
