[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an environmentally friendly dust and fume removal device for welding, comprising a welding table and a support assembly;

[0007] The support assembly is fixed inside the welding table. A suction port is opened on the front side of the welding table. The inner wall of the suction port is slidably fitted with the filter frame. An air extraction port is opened on the bottom surface inside the welding table. The bottom end of the air extraction port is fixedly connected to the air collection chamber. An exhaust pipe is fixedly installed below the air collection chamber. A positioning assembly is slidably installed on the rear side of the welding table.

[0008] A further feature of this invention is that the support assembly includes a fixed frame whose outer side is at the same height as the welding table, a groove formed on the fixed frame, and support rods whose two ends slide along the groove.

[0009] By adopting the above technical solution, installation support is provided for both ends of the strut.

[0010] A further feature of this invention is that the bottom surface of the filter frame is an open structure, and a filter screen is fixedly provided on the bottom surface of the filter frame.

[0011] By adopting the above technical solution, when the debris received on the filter screen needs to be processed, the filter frame can be directly pulled out.

[0012] A further feature of this invention is that the air extraction port is located within the downward vertical orthographic projection range of the filter screen.

[0013] By adopting the above technical solution, welding fumes can be smoothly extracted from the exhaust port, while debris is collected in the filter screen.

[0014] A further feature of this invention is that the positioning component includes a retaining plate slidably disposed on the welding table, a driving component that slidably engages with the rear end of the retaining plate, and a resetting component that helps the retaining plate move and reset.

[0015] By adopting the above technical solution, the support rod is fixed by the fixing plate, so that the support rod can remain fixed during welding.

[0016] A further feature of this invention is that a sliding opening is provided on the rear side of the welding table, and the outer side of the fixing plate is slidably connected to the sliding opening.

[0017] By adopting the above technical solution, the retaining plate can be stably slid in a straight line in the back-and-forth direction on the welding table.

[0018] A further feature of this invention is that the fixing frame has an insertion port on the side near the fixing plate, and a pressure plate is fixed on the side of the fixing plate near the fixing plate.

[0019] By adopting the above technical solution, the pressure plate can move back and forth under the action of the stationary plate.

[0020] A further feature of this invention is that the inner end of the pressure plate slides into the socket and comes into contact with the support rod.

[0021] By adopting the above technical solution, the pressure plate applies force to the strut to keep it in place.

[0022] A further feature of this invention is that the retaining plate has an inclined groove on the side near the driving assembly, and the driving assembly includes a push plate whose top end slides in cooperation with the inclined groove, a support fixed to the bottom end of the push plate, a cylinder whose output end is fixedly connected to the support, and a mounting seat fixed to the outside of the cylinder.

[0023] By adopting the above technical solution, when the cylinder pushes the push plate upward, the push plate will exert force on the inclined groove, causing the retaining plate to move forward.

[0024] A further feature of this invention is that the reset assembly includes a support plate whose top end is fixedly connected to the retaining plate and springs whose two ends are respectively fixed to the support plate and the welding table.

[0025] By adopting the above technical solution, when the push plate moves down, the retaining plate can move outward by the elastic force of the spring, causing the pressure plate to separate from the support rod.

[0026] The beneficial effects of this utility model are:

[0027] During welding, the workpiece is placed on the support rod for operation. The welding debris can fall directly into the filter screen for collection, while the fumes can be quickly directed downwards through the exhaust port, reducing the contact between the fumes and the workers to protect the health of the workers and the environment. At the same time, the support rod can be quickly moved by the positioning component to adjust the spacing between them to meet the welding needs of different sized workpieces, thereby improving the convenience and effectiveness of use.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] This utility model embodiment specifically provides an environmentally friendly dust and fume removal device for welding. Please refer to... Figures 1-3 It includes a welding station 1 and a support assembly 2.

[0035] The support component 2 is fixed inside the welding table 1. The welding table 1 has a pull-out port 11 on the front side. The inner wall of the pull-out port 11 is slidably engaged with the filter frame 3 to facilitate the extraction of the filter frame through the pull-out port 11. A handle 32 is fixedly installed on the outer side of the filter frame 3 so that the handle 32 can extract the filter frame 3 from the pull-out port 11.

[0036] Specifically, the bottom surface of the welding table 1 is provided with an exhaust port 4, the bottom end of which is fixedly connected to the gas collection chamber 5. An exhaust pipe 6 is fixedly provided below the gas collection chamber 5. The exhaust pipe 6 is used to connect to an external fume collection pipe so that when fumes are generated during welding, the fumes are discharged through the exhaust port 4 and the exhaust pipe 6. A positioning component is slidably provided on the rear side of the welding table 1.

[0037] Furthermore, the support assembly 2 includes a fixed frame 21 that maintains the same height as the welding table 1 on the outside, a slide groove 22 opened on the fixed frame 21, and a strut 23 that slides along the slide groove 22 at both ends. There are two fixed frames 21, which are symmetrically arranged at the front and rear of the welding table 1 to provide installation support for the two ends of the strut 23.

[0038] During welding, the welding rod can be placed on the support rod 23 for welding, so that the welding debris falls into the filter frame 3 through the gap between the support rods 23 for collection, and the welding fumes are extracted through the exhaust port 4.

[0039] Specifically, the bottom surface of the filter frame 3 is an open structure, and a filter screen 31 is fixedly installed on the bottom surface of the filter frame 3. The bottom of the filter screen 31 is in sliding contact with the welding table 1, so that when the debris received on the filter screen 31 needs to be processed, the filter frame 3 can be directly pulled out.

[0040] The exhaust port 4 is located within the downward vertical projection range of the filter screen 31, allowing welding fumes to be smoothly extracted from the exhaust port 4, while debris is collected in the filter screen 31.

[0041] Furthermore, when it is necessary to adjust the spacing of the support rods 23 to accommodate welding of different sized parts, the positioning assembly includes a retaining plate 7 slidably disposed on the welding table 1, a driving assembly 8 that slides with the rear end of the retaining plate 7, and a resetting assembly 9 that helps the retaining plate 7 move and reset. The retaining plate 7 fixes the support rods 23 in place so that the support rods 23 can remain fixed during welding.

[0042] Specifically, a sliding opening 12 is provided on the rear side of the welding table 1, and the outer side of the fixing plate 7 is slidably connected to the sliding opening 12, so that the fixing plate 7 can stably slide in a straight line in the back and forth direction on the welding table 1.

[0043] The fixing frame 21 has an insertion port 24 on the side near the fixing plate 7, and the fixing plate 7 has a pressure plate 71 fixed on the side near the fixing plate 7. The fixing frame 21 refers to the one near the fixing plate 7, so that the pressure plate 71 can move back and forth under the action of the fixing plate 7.

[0044] During implementation, the inner end of the pressure plate 71 slides into the socket 24 and comes into contact with the support rod 23. During daily use, the pressure plate 71 applies force to the support rod 23 to keep it in place. If it is necessary to adjust the gap of the support rod 23, the pressure plate 71 is separated from the support rod 23. Then, the support rod 23 is slid on the slide groove 22 to adjust the gap between them to accommodate objects of different sizes.

[0045] Furthermore, the retaining plate 7 has a sloping groove 72 on the side near the drive assembly 8. The drive assembly 8 includes a push plate 81 with its top end slidingly engaged with the sloping groove 72, a support 82 fixedly mounted on the bottom end of the push plate 81, a cylinder 83 with its output end fixedly connected to the support 82, and a mounting seat 84 fixedly mounted on the outside of the cylinder 83. The mounting seat 84 is fixedly connected to the outside of the welding table 1. The top end of the push plate 81 has an arc structure, so that when the cylinder 83 pushes the push plate 81 upward, the push plate 81 will exert force on the sloping groove 72, causing the retaining plate 7 to move forward, so that the pressure plate 71 exerts force on the support rod 23.

[0046] The reset assembly 9 includes a support plate 91 fixedly connected to the top of the retaining plate 7 and springs 92 fixed at both ends to the support plate 91 and the welding table 1 respectively. When the push plate 81 moves down, the retaining plate 7 can move outward by the elastic force of the spring 92, causing the pressure plate 71 to separate from the support rod 23.

[0047] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
