Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a sandblasting device for glass surface treatment. Background Technology

[0002] Sandblasting technology plays a vital role in glass production, enabling glass products to be more creative, aesthetically pleasing, and flexible, with a wider range of applications. Sandblasting utilizes air pressure to draw up abrasive particles, which are then expelled from a spray gun through pipes. The dust and noise generated during operation can significantly impact the health of operators. While existing glass sandblasting machines have achieved automation and high efficiency in glass sandblasting, some shortcomings still exist in practical use.

[0003] For example, Chinese utility model patent CN220592804U discloses a sandblasting mechanism for tempered glass. In this mechanism, the tempered glass moves forward via a bottom conveying mechanism and a top clamping mechanism during production. A first sandblasting component and a second sandblasting component respectively sandblast the upper and lower surfaces of the tempered glass. Sandblasting does not require clamping or fixing the glass; the glass is sandblasted while being conveyed, resulting in high efficiency. However, sand residue remains on the glass surface during sandblasting. When the glass passes the rollers of the bottom conveying mechanism and the top clamping mechanism, the sand squeezes and rubs against the glass, damaging the surface and affecting the sandblasting quality. Utility Model Content

[0004] The purpose of this invention is to provide a tempered glass sheet sandblasting mechanism to solve the problems mentioned in the background art.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a sandblasting device for glass surface treatment, comprising a worktable, a conveying assembly disposed on the worktable, a sandblasting chamber disposed above the conveying assembly, and a sandblasting component disposed within the sandblasting chamber, further comprising:

[0006] A clamping assembly is disposed above the conveying assembly and is located on the front and rear sides of the sandblasting assembly. The clamping assembly can move up and down relative to the conveying assembly.

[0007] A cleaning component, positioned above the conveying component and between the sandblasting component and the subsequent clamping component, is used to clean sand from the glass surface.

[0008] Preferably, the clamping assembly includes a clamping bracket, a movable bracket disposed on the clamping bracket, and a clamping roller disposed on the movable bracket.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0027] Example: Figure 1 and Figure 2 As shown, a sandblasting device for glass surface treatment includes a worktable 1, a conveying assembly 2 disposed on the worktable 1, a sandblasting chamber 3 disposed above the conveying assembly 2, and a sandblasting component 4 disposed in the sandblasting chamber 3. A pressing component 5 and a cleaning component 6 are disposed in the sandblasting chamber 3.

[0028] Among them, the conveying component 2 is a conventional conveying roller, which is a powered roller used to convey the glass to be sandblasted.

[0029] The sandblasting assembly 4 is a conventional assembly. Specifically, the sandblasting assembly 4 includes multiple nozzles, an air compressor that provides the high-pressure air power required for sandblasting, and a delivery pipe that transports sand from the sand storage hopper to the sandblasting gun.

[0030] The clamping component 5 is positioned above the conveying component 2 and is located on the front and rear sides of the sandblasting component 4. The clamping component 5 can move up and down relative to the conveying component 2.

[0031] like Figure 3As shown, the clamping assembly 5 includes a clamping bracket 501, a movable bracket 502 mounted on the clamping bracket 501, and a clamping roller 503 mounted on the movable bracket 502. The clamping bracket 501 is fixed to the table surface of the workbench 1. Vertical sliding grooves 504 are provided on both sides of the clamping bracket 501. The two ends of the movable bracket 502 are slidably mounted on the sliding grooves 504 of the clamping bracket 501, allowing the movable bracket 502 to move up and down. The clamping roller 503 is a non-powered roller, mounted on the movable bracket 502 via a rotating shaft.

[0032] like Figure 4 As shown, the pressure roller 503 has two sets of protruding strips 5031 on its surface. The protruding strips 5031 are spirally wound around the pressure roller 503, and the spiral directions of the two sets of protruding strips 5031 are opposite. The protruding strips 5031 are made of rubber. During the glass conveying process, the pressure roller 503 rotates as the glass moves, and the two sets of protruding strips 5031 on the roller surface of the pressure roller 503 play a role in preventing slippage.

[0033] An adjustment assembly is provided between the pressing bracket 501 and the movable bracket 502. The adjustment assembly includes an adjustment seat 504 disposed above the movable bracket 502, a spring 506 connected between the adjustment seat 504 and the movable bracket 502, and a cylinder 507 connected between the adjustment seat 504 and the pressing bracket 501. It can adjust the pressure applied to the glass by the pressing roller 503 and can adapt to glass of different thicknesses.

[0034] The cleaning component 6 is positioned above the conveying component 2 and between the sandblasting component 4 and the rear clamping component 5, and is used to clean sand from the glass surface.

[0035] like Figure 5 As shown, the cleaning assembly 6 includes a cleaning box 601, an air inlet 602 and an air knife 603 disposed inside the cleaning box 601, and a cleaning roller 604. The cleaning box 601 is fixed on the table surface of the workbench 1. The cleaning box 601 has slots 606 for glass to enter and exit on the side walls on the front and rear sides. Rubber baffles 607 are provided at the slots 606.

[0036] The air inlet 602 and the air knife 603 are distributed in a front-to-back manner, and the cleaning roller 604 is disposed between the air inlet 602 and the air knife 603.

[0037] The air intake 602 is connected to the exhaust fan and the dust collector bag through the air intake pipe, and the dust in the cleaning box 601 is sucked up by negative pressure.

[0038] The air knife 603 is inclined downwards, and the cleaning roller 604 is located on the side close to the air knife 603. The air knife 603 is connected to a blower through a blower pipe. The blower blows high-speed airflow into the air knife 603, which is then blown onto the glass surface through the strip-shaped air outlet of the air knife 603, and blows the sand towards the cleaning roller 604 for cleaning.

[0039] The cleaning roller 604 is equipped with brushes arranged in a spiral pattern on its surface. A drive motor is mounted at one end of the cleaning roller 604, and a discharge port 605 is located at the other end, situated on the side wall of the cleaning box 601. When the drive motor rotates the cleaning roller 604, the spirally arranged brushes push the sand below axially until it enters the discharge port 605, where a collection box is installed to collect the sand.
