Description

Technical Field

[0001] This invention relates to glass edging machines, and more particularly to a spraying and recycling device for glass edging machines. Background Technology

[0002] Currently, the water spraying devices widely used in the industry for glass edging machines mostly adopt fixed single-sided or double-sided spraying structures, which have the following technical defects: First, the spray nozzle position is fixed and cannot be adjusted synchronously with the contact point between the grinding wheel and the glass, resulting in large spraying position deviations and unstable cooling and dust reduction effects; Second, to ensure processing results, a large water volume spraying mode is required, which consumes a large amount of water, increasing water consumption and making subsequent recycling and treatment of the water and glass powder mixture more difficult; Third, existing recycling devices mostly use direct negative pressure suction, which allows glass powder to easily enter core components such as the fan with the water flow, causing problems such as fan impeller wear, bearing damage, and air duct blockage, shortening equipment lifespan and increasing maintenance costs.

[0003] Furthermore, some high-precision spraying devices suffer from complex structures, high processing accuracy requirements, and high manufacturing costs, making them unsuitable for mass production and low-cost applications. Therefore, developing a spraying and recycling device for glass edging machines that offers precise spraying, low water consumption, high recycling efficiency, and effective protection against glass powder has become a pressing technical challenge in this field. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides a spraying and recovery device for a glass edging machine, comprising a frame, a water cover shell, a turntable bearing, a spray pipe, a lower water tray, a negative pressure recovery system, and a double-layer vacuum tube; the water cover shell is fixed to the frame, the turntable bearing is assembled to the water cover shell, the spray pipe is connected to the turntable bearing and can rotate synchronously, and the spray nozzle of the spray pipe is aligned with the contact area between the grinding wheel and the glass; the lower water tray and the water cover shell enclose a mixed liquid collection space; the negative pressure recovery system is connected to the double-layer vacuum tube for recovering the mixed liquid; the vacuum tube includes an outer tube and an inner tube, the inner tube being provided with multi-stage electrostatic adsorption fins for adsorbing glass powder.

[0005] Furthermore, the electrostatic adsorption fins are obliquely shaped and have a flow guide angle of 30° to 45° with the airflow direction. Each stage has 3 to 5 fins evenly arranged along the circumference, and the fins of the preceding and following stages are arranged alternately to form a labyrinthine adsorption channel.

[0006] Furthermore, the electrostatic adsorption fins and inner tube are made of a special rubber with high insulation, wear resistance, and easy static electricity generation, with a thickness of 2 to 3 millimeters, and are integrally formed with the inner tube or bonded at high temperature.

[0007] Furthermore, the special rubber is an electrostatic electret rubber.

[0008] Furthermore, the negative pressure recovery system includes a return water tank, a fan, a telescopic pipe, and a return water connector; the fan and the return water tank are connected to form a negative pressure environment, and the mixed liquid is sucked into the return water tank through the return water connector, the telescopic pipe, and the vacuum pipe; the return water tank is connected to a water tank to realize water recycling; a silencer is provided at the air outlet of the fan.

[0009] Furthermore, the inner tube and outer tube can be separated, making it easy to replace or clean the inner tube.

[0010] This invention utilizes a rotatable and adjustable spray structure to ensure that the spray nozzles are always precisely aligned with the processing contact area between the grinding wheel and the glass, significantly improving cooling, lubrication, and dust suppression effects, effectively reducing water consumption and decreasing the pressure on the mixed solution. The separation structure, composed of double-layered tubes and multi-stage electrostatic adsorption fins, efficiently adsorbs and traps glass powder, preventing it from entering core components such as the fan at the source, thus preventing equipment wear, damage, and duct blockage, significantly extending equipment lifespan and reducing maintenance costs. Simultaneously, the overall device has a simple and reliable structure, suitable for mass production and low-cost applications. The recovered water can be recycled, resulting in a clean processing environment. Overall, this invention achieves the technical effects of precise spraying, water conservation and high efficiency, reliable protection, and stable operation.

[0011] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention; Figure 2 yes Figure 1 A magnified view of a portion of the image. Detailed Implementation

[0013] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0014] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0015] See Figure 1 and 2The spraying and recycling device of this glass edging machine is integrally mounted on the machine frame 18. The water cover housing 21 is fixedly connected to the machine frame 18, providing a stable installation foundation for the overall structure. The turntable bearing 20 is fixedly mounted on the water cover housing 21. The water spray pipe 22 is connected to the turntable bearing 20 and can rotate synchronously with it, ensuring that the water spray nozzle at the lower end of the water spray pipe 22 is always aligned with the working contact area between the grinding wheel 25 and the glass. The grinding wheel 25 is connected to the main shaft 19 through the tool holder 24 and rotates at high speed under the drive of the main shaft 19 to complete the glass edging process.

[0016] The water spray pipe 22 sprays high-pressure cooling water downwards, directly acting on the friction area between the grinding wheel 25 and the glass to achieve cooling, lubrication, and dust suppression. The used water and glass powder mixture collects in the space enclosed by the lower water tray 23 and the water cover shell 21. The fan 32 is connected to the return water tank 31 to form a negative pressure recovery system. The small port of the fan 32 is a negative pressure port, creating a negative pressure environment inside the return water tank 31. Under the action of the negative pressure wind, the mixture is sucked into the return water tank 31 through the return water connector 26, the telescopic pipe 27, and the vacuum pipe 10.

[0017] The vacuum tube 10 adopts a double-layer tube structure, including an outer tube 11 and an inner tube 12. The inner tube 12 contains multiple stages of electrostatic adsorption fins 13. The electrostatic adsorption fins 13 are obliquely plate-shaped, forming a 30° to 45° guide angle with the airflow direction. Each stage has 3 to 5 fins evenly arranged along the circumference, with the fins from each stage staggered to form a labyrinthine adsorption channel. The electrostatic adsorption fins 13 and the inner tube are made of a special rubber with high insulation, wear resistance, and high static electricity generation, with a thickness of 2 to 3 mm. They are integrally molded with the inner tube 12 or bonded at high temperature to ensure they do not detach or leak during use. The inner tube 12 can be separated from the outer tube 11 for periodic replacement or cleaning.

[0018] When the water-air mixture containing glass powder passes through the inner tube 11 at high speed, the airflow rubs against the electrostatic adsorption fins 13 at high speed, generating stable static electricity on the fin surface. As the mixture flows through, the glass powder is strongly adsorbed onto the surface of the fins 13 by the static electricity, achieving separation of the powder from the water and air. The trapped glass powder remains on the fin segment, while clean water and air continue to enter the return water tank 31, preventing glass powder from entering the fan 32 at the source, thus avoiding impeller wear, bearing damage, and duct blockage.

[0019] After air-water separation in the return water tank 31, the clean water flows downstream into the water tank 30, achieving water recycling. The rotary joint 28 is fixed to the ground via the column 29, ensuring a stable and reliable connection between the telescopic pipe 27 and the rotating components. A silencer 33 is installed at the air outlet of the fan 32 to reduce operating noise while ensuring normal airflow. The entire system sprays and recovers water simultaneously during the glass edging process. The spraying position is precise, the water consumption is small, and there is no obvious residual water on the processed glass surface, maintaining a good processing environment.

[0020] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
