[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Reference Figure 1-4 A sandblasting device for traffic signs includes a base 1, a protective box 2 fixedly connected to the top of the base 1, a protective door 201 rotatably connected to the outside of the protective box 2, a sandblasting head 502 disposed on the inner top wall of the protective box 2, and a collection component and a clamping component. The collection component includes a collection funnel 3 fixedly connected to the inner bottom wall of the protective box 2, a fan 302 fixedly connected to the bottom of the collection funnel 3, an electrostatic adsorption component 303 fixedly connected to the inside of the collection funnel 3, and a grid plate 301 fixedly connected to the top of the collection funnel 3. The clamping component is disposed inside the protective box 2 and is used to clamp the workpiece.

[0028] The traffic signs to be processed are fixed on the clamping assembly. After the protective door 201 is closed, the sandblasting head 502 is started to carry out sandblasting. The waste and dust generated during the sandblasting process are drawn into the collection funnel 3 through the grid plate 301 by the suction of the fan 302. The electrostatic adsorption component 303 can effectively adsorb fine metal particles and dust, realizing efficient recycling and environmentally friendly treatment of waste. At the same time, the protective box 2 can effectively prevent dust from overflowing, ensuring a clean and safe working environment. It can effectively improve sandblasting efficiency and quality, reduce abrasive wear and environmental pollution. In addition, it should be noted that the electrostatic adsorption component 303 converts the DC power supply into stable DC power after step-down, rectification, filtering and voltage stabilization. Then, the DC power is converted into alternating current through a self-excited oscillator. Then, it is converted into high-voltage DC power through a boost circuit and a multi-stage voltage multiplier rectifier circuit. Finally, the charge is released through an electrostatic emission device such as a metal plate to complete the adsorption.

[0029] Reference Figure 2-5 A sandblasting device for the surface of traffic signs is further provided, wherein the protective door 201 is provided with an observation window 202 on the outside, and the protective door 201 is provided with a handle and a door lock on the outside; the base 1 is provided with a storage space inside, and a switch door is provided on the front side of the base 1; the base 1 is provided with a recycling tank 6 and a storage tank 7 inside; the output end of the blower 302 is fixedly connected to the input port of the recycling tank 6, and the input end of the sandblasting head 502 is connected to the inside of the storage tank 7 through a pipe.

[0030] The observation window 202 is equipped with a transparent panel inside, which can block the inside and outside space while facilitating external observation. The door lock can ensure that the protective door 201 is tight when closed. The storage tank 7 is used to store new abrasive. The fan 302 can generate suction to draw the abrasive into the collection funnel 3 and store the processed abrasive through the recycling tank 6, which facilitates the collection of waste.

[0031] The sandblasting head 502 is externally fixedly connected to a connecting plate 501, the top of the connecting plate 501 is provided with an electric guide rail 5, and the bottom two sides of the connecting plate 501 are fixedly connected to jet heads 503.

[0032] The jet nozzle 503 can spray gas to clean the surface of the workpiece, reduce abrasive residue and improve the processing effect. The electric guide rail 5 drives the sandblasting head 502 and the jet nozzle 503 to move through the connecting plate 501, which facilitates processing of multiple positions of the workpiece and improves processing efficiency.

[0033] Reference Figure 4A sandblasting device for traffic sign surfaces, further comprising a clamping assembly including a drive motor 4 fixedly connected to the outside of a protective housing 2, a drive gear 401 fixedly connected to the output end of the drive motor 4, a driven gear 402 meshing with the outside of the drive gear 401, a sleeve 403 fixedly connected inside the driven gear 402, an electric push rod 405 fixedly connected inside the sleeve 403, a clamping plate 406 rotatably connected to the output end of the electric push rod 405, and an auxiliary rotating disk 404 rotatably connected to one side of the clamping plate 406; the auxiliary rotating disk 404 has a bearing inside, and the bearing is fixedly connected to the outside of the sleeve 403, with the bearing inside the auxiliary rotating disk 404 extending along the sleeve 403; and a protective shell is provided outside the drive motor 4.

[0034] The drive motor 4 drives the driven gear 402 to rotate via the drive gear 401, thereby driving the sleeve 403 and the electric push rod 405 inside to rotate synchronously. The output end of the electric push rod 405 is connected to the clamping plate 406 via a rotating plate. One end of the clamping plate 406 is rotatably connected to the auxiliary rotating disk 404, so the other end of the clamping plate 406 can be opened and closed. When the electric push rod 405 extends or retracts, it can push the clamping plate 406 to open and close. The setting of the auxiliary rotating disk 404 makes the clamping plate 406 stable during rotation. This clamping assembly can realize automatic clamping and rotation of the sign, ensuring uniform and comprehensive sandblasting treatment. At the same time, the structure is stable and reliable, and the operation is flexible and convenient, which greatly improves the efficiency and quality of sandblasting operations.

[0035] Specifically, in use, the following steps are taken: First, the identification plate is placed inside the clamping assembly. Then, the electric push rod 405 is activated to open and close one end of the clamping plate 406. When closed, the workpiece can be clamped. Then, the protective door 201 is closed, and the sandblasting head 502 is activated to spray abrasive onto the workpiece. During further processing, the electric guide rail 5 is activated to move the sandblasting head 502. The drive motor 4 is then activated to drive the driven gear 402 to rotate via the drive gear 401, thereby driving the sleeve 403 and the electric push rod 4 inside it. The synchronous rotation of the 05 clamping plate 406 and the workpiece allows for simultaneous rotation, enabling processing of multiple positions on the workpiece. This reduces manual turning and facilitates use. Waste and dust generated during sandblasting are drawn into the collection funnel 3 through the grid plate 301 by the suction of the blower 302. The electrostatic adsorption component 303 effectively adsorbs fine metal particles and dust. After adsorption is complete, the power is disconnected, causing the waste to fall into the collection funnel 3. The collected waste is stored in the recycling tank 6, facilitating cleaning and improving ease of use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
