Description

Technical Field

[0001] This invention relates to the field of welding dust prevention technology, specifically a dust prevention device for welding. Background Technology

[0002] Welding generates a large amount of welding fumes and harmful gases. These fumes contain various metal oxide particles, and long-term inhalation can cause serious damage to the human respiratory system and other systems, easily leading to occupational diseases such as pneumoconiosis. Harmful gases such as ozone, carbon monoxide, and nitrogen oxides can also harm the human respiratory tract and nervous system. Therefore, it is necessary to take dust prevention measures.

[0003] Application No. 202123304597.3 discloses a dustproof device for a laser welding machine that uses a dust cover, a dust collection box, a dust collection filter and a pull plate in combination to collect the dust generated by the welding machine body during operation.

[0004] The aforementioned welding dust prevention device uses the same method as most welding dust prevention devices on the market, which uses isolation methods such as boxes to prevent dust. However, this method is not convenient and affects the operable space during the welding process. Therefore, in view of this situation, this utility model proposes a new solution. Summary of the Invention

[0005] The purpose of this invention is to provide a dustproof device for welding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dustproof device for welding, comprising:

[0007] The welding table and mounting frame are provided. The top of the mounting frame is equipped with a welding seat for welding, and the bottom of the mounting frame is equipped with a power mechanism.

[0008] The power mechanism includes an air supply component and a power component. The air supply component forms an air screen around the welding seat, and the power component provides power for the rotation of the welding seat.

[0009] Further, the welding seat includes a base plate and a circular platform rotating in the middle of the base plate, wherein the base plate is also a circular plate and its diameter is larger than that of the circular platform.

[0010] Further, the air supply component includes several branch pipes, each of which passes through the mounting bracket and the base plate and is placed on the base plate. Each branch pipe has a nozzle fixed at its top. The branch pipes are arranged around the base plate, and the nozzle outlet end is flat.

[0011] Further, the welding station is fixed with a bottom box on top. The bottom box is hollow inside and a merging pipe is fixed on the top. One end of each branch pipe is fixed to the merging pipe. A blower is installed on one side of the bottom box to blow air into the bottom box.

[0012] Further, a connecting shaft is rotatably mounted at the top center of the mounting frame. The connecting shaft passes through the base plate and is coaxially fixed with the circular base. A sprocket is fixed on the surface of the connecting shaft. A connecting plate is fixed on one side of the mounting frame. A drive source is mounted at the bottom of the connecting plate. A sprocket is also fixed at the output end of the drive source. The two sprockets are connected by a chain.

[0013] Furthermore, the welding table is equipped with a support arm on top, the top of which is at a right angle, and a suction tube is fixed to the top of the support arm, with a top cover fixed to the bottom of the suction tube.

[0014] Furthermore, the straw is vertically arranged and coaxially with the welding seat, wherein the diameter of the top cover is at least larger than the diameter of the circular base, and the distance between the top cover and the top of the circular base is 5cm-20cm.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This welding dustproof device, by incorporating power and air supply components, can collect dust and harmful gases during the welding process without significantly affecting the workable space of the welding station. This allows for more efficient use of space on the welding station, minimizes the impact of dust collection on the welding process, and ensures that the welding process is not obstructed, reducing visual obstructions caused by partitions.

[0017] Meanwhile, the drive source drives the connecting shaft to rotate through the transmission of sprockets and chains, thereby causing the circular platform to rotate synchronously on the base plate. This rotation function allows for convenient welding of workpieces at different angles during the welding process, improving the flexibility and efficiency of welding. Moreover, during the rotation process, the presence of the air screen can still effectively block the spread of dust. In other words, the device simultaneously meets the requirements for dust prevention and welding angle adjustment. Attached Figure Description

[0022] 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention provides a technical solution: a dustproof device for welding, comprising:

[0024] The welding table 1 and the mounting frame 6 are provided. The top of the mounting frame 6 is equipped with a welding seat 5 for welding. The bottom of the mounting frame 6 is equipped with a power mechanism 7, which includes an air supply component and a power component. The air supply component forms an air screen around the welding seat 5, and the power component provides power for the rotation of the welding seat 5.

[0025] Further regarding this scheme, the welding seat 5 includes a base plate and a circular platform rotating in the middle of the base plate, wherein the base plate is also a circular plate and its diameter is larger than that of the circular platform.

[0026] The welding table 1 provides a stable foundation platform for the entire device. It is made of high-strength steel to ensure that it can withstand various external forces during the welding process without deformation, thus ensuring the stability of the device. The mounting frame 6 is fixed to the welding table 1 by bolts and other sturdy connectors. The mounting frame 6 is designed as a square frame structure, which ensures sufficient strength and provides ample space and convenience for installing other components.

[0027] like Figure 2 As shown, further details of this scheme include an air supply component comprising several branch pipes 703. Each branch pipe 703 passes through the mounting bracket 6 and the base plate before being positioned on the base plate. A nozzle 704 is fixed to the top of each branch pipe 703. The branch pipes 703 are arranged around the base plate, and the outlet end of the nozzle 704 is flattened. The branch pipes 703 are evenly distributed in a ring around the base plate, ensuring the formation of a complete and uniform air screen around the welding seat 5, effectively preventing dust and smoke from spreading to the surrounding area. The outlet shape of the nozzle 704 allows the ejected airflow to form a suitable coverage area and wind intensity, effectively blocking dust without excessively interfering with the welding operation.

[0028] like Figure 2 As shown, further regarding this scheme, a base box 701 is fixed on the top of the welding station 1. The base box 701 is hollow inside and a merging pipe 702 is fixed on the top. One end of each branch pipe 703 is fixed to the merging pipe 702. A blower 705 is provided on one side of the base box 701 to blow air into the base box 701.

[0029] like Figure 2 As shown, further regarding this scheme, a connecting shaft 708 is rotatably mounted at the top center of the mounting bracket 6. The connecting shaft 708 passes through the base plate and is coaxially fixed with the circular base. A sprocket 709 is fixed on the surface of the connecting shaft 708. A connecting plate 706 is fixed on one side of the mounting bracket 6. A drive source 707 is mounted at the bottom of the connecting plate 706. A sprocket 709 is also fixed at the output end of the drive source 707. The two sprockets 709 are connected by a chain 710. The connecting shaft 708 and the sprocket 709 are connected by a key to achieve synchronous rotation, ensuring that the power can be stably and reliably transmitted to the circular base.

[0030] Furthermore, the top of the welding table 1 is also equipped with a support arm 2, the top of the support arm 2 is right-angled, and a suction tube 3 is fixed to the top of the support arm 2, and a top cover 4 is fixed to the bottom of the suction tube 3.

[0031] Further, the straw 3 is vertically arranged and coaxially with the welding seat 5. The diameter of the top cover 4 is at least larger than the diameter of the circular base, and the distance between the top cover 4 and the top of the circular base is 5cm-20cm.

[0032] During the welding process, the blower 705 is started first, blowing air into the bottom box 701. The air enters each branch pipe 703 through the merging pipe 702 and is then sprayed out from the nozzle 704, forming a high-speed airflow screen around the welding seat 5. This screen can effectively block the dust, smoke and spatter generated during the welding process from spreading to the surroundings, confining them to a certain area around the welding seat 5, thereby reducing dust pollution to the surrounding environment and harm to the health of operators.

[0033] The drive source 707 drives the connecting shaft 708 to rotate through the transmission of the sprocket 709 and the chain 710, thereby causing the circular platform to rotate synchronously on the base plate. This rotation function allows for convenient welding of the workpiece at different angles during the welding process, improving the flexibility and efficiency of welding. Moreover, during the rotation process, the presence of the air screen can still effectively block the spread of dust.

[0034] In addition, the suction pipe 3 and the top cover 4 at the top of the support arm 2 also play a role. The top cover 4 partially encloses the space above the welding seat 5, so that the welding fumes are captured by the top cover 4 during the rising process, and then sucked into the subsequent dust removal system (not described in detail in the above scheme, but can be connected to external dust removal equipment, which is the prior art) through the suction pipe 3 for centralized treatment, further reducing the suspension and diffusion of dust in the air.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
