Description

Technical Field

[0001] The invention relates to the technical field of bathing chair production and processing, in particular to a welding device capable of automatically cleaning welding slag for bathing chair production. Background Art

[0002] Bath chairs are used for bathing in the bathroom. They look similar to ordinary chairs and are suitable for people with limited mobility, such as the elderly, pregnant women, and the disabled. The difference between bath chairs and ordinary chairs is that bath chairs are used for bathing in the bathroom. According to different groups of people and their different needs, they are designed to be more humane in details. Bath chairs not only allow them to complete the task of bathing independently, but also make bathing healthier. However, the production and processing of bath chairs usually require welding, grinding, and painting.

[0003] The existing welding device for automatically cleaning welding slag used in the production of bathing chairs has the following problems during use: first, the debris and dust generated during the welding of the bathing chair cannot be handled in time, and is usually handled manually by the staff after completion, which is inconvenient, time-consuming and labor-intensive. In addition, the welder still retains heat after use, which poses a certain risk during manual cleaning. Second, the iron slag and dust after cleaning are usually collected and thrown away together. However, the iron slag generated during welding can also be used for other purposes during production and processing, which causes waste. Third, after welding is completed, the welded area usually needs to be polished and painted. After polishing, a large amount of polishing dust still remains on the outer surface of the bathing chair, which cannot be handled in time before painting, thereby affecting the painting effect and needs further improvement. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a welding device for bathing chair production that can automatically clean welding slag.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By setting up a collection mechanism, during use, through the operation of the motor, the three rotating columns rotate, so that the three first fans rotate. When the three first fans rotate, negative pressure is generated, which can timely adsorb and collect dust and iron slag during welding, eliminating the need for manual handling. The operation is simple and convenient, improving the welding processing environment. With the cooperation of the partition plate, the adsorbed dust and iron slag are conveniently collected into the separation box for subsequent processing.

[0016] 2. By setting up a separation mechanism, the collected dust and iron slag are transported to the separation box. Under the rotation of the two shaft columns, the four cams continuously touch the filter plate, causing the filter plate to move up and down under the guidance of the four second I-shaped parts. The four springs are continuously stretched or compressed, facilitating the rapid separation of dust and iron slag. The separated iron slag can be recycled and reused.

[0017] 3. By setting up an auxiliary mechanism, while the motor is running, its third worm and fourth worm respectively drive the four third worm wheels to rotate, and the four second fan blades rotate accordingly. When the welding is completed and polished, the dust on the surface can be blown away in time to facilitate the subsequent painting process, thereby improving the painting effect. In addition, the cooperation of the four second fans can also gather the iron slag dust splashed by welding in the middle of the protective box during welding, which is convenient for collection.

One end of the second connecting rod 315 penetrates to the inside of the opening 310 and is hinged with the top of the sleeve plate 308. Through holes that are mutually adapted to the outer parts of the two first I-shaped parts 307 are opened on the sleeve plate 308.

[0033] The rotation of the three first fans 304 generates negative pressure, facilitating the adsorption of iron filings and dust generated during welding into the inside of the pipe body 301. Blocked by the partition plate 316, it enters the inside of the separation box 402 through the conveying pipe 401.

[0034] The separating mechanism 4 includes a conveying pipe 401. The lower left side of the pipe body 301 is connected to a separating box 402 through the conveying pipe 401 in a through manner. Both the front and rear parts on both sides inside the separating box 402 are fixedly connected with second I-shaped members 403. Filter plates 404 are sleeved outside the four second I-shaped members 403. The filter plates 404 are inclined. Through holes that are mutually adapted in size to the outside of the four second I-shaped members 403 are formed in the filter plates 404. Springs 405 are provided below the filter plates 404 and outside the four second I-shaped members 403. A first runner 406 is arranged outside the rotating shaft 312.

A third runner 410 is fixedly connected to the right side of the connecting column 409. The third runner 410 is in driving connection with a fourth runner 412 through a second belt 411. Shaft columns 413 are fixedly connected to the right sides of both the third runner 410 and the fourth runner 412. Both of the two shaft columns 413 penetrate into the inside of the separating box 402 and are rotatably connected to the right inner wall of the separating box 402. Two cams 414 are fixedly connected to the outside of both of the two shaft columns 413. The two cams 414 outside the two shaft columns 413 are symmetrically arranged. A discharge port 415 is formed in the upper right part of the separating box 402. A discharge pipe 416 is arranged in the lower right part of the separating box 402.

[0035] The rotation of the third runner 410 and the fourth runner 412 causes the two shaft columns 413 to rotate, causing the four cams 414 to continuously touch the filter plates 404, causing the filter plates 404 to move up and down under the guidance of the four second I-shaped members 403, and the four springs 405 to be continuously stretched or compressed, facilitating the rapid separation of dust and iron slag and facilitating recycling and reuse.

[0036] The auxiliary mechanism 5 includes a connecting shaft 501. The left side of the fourth runner 412 is fixedly connected to the connecting shaft 501. The left side of the connecting shaft 501 is fixedly connected to a fifth runner 502. A transmission connection is formed between the fifth runner 502 and a sixth runner 504 via a third belt 503. The right side of the sixth runner 504 is fixedly connected to a second worm 505. One end of the second worm 505 is rotatably connected to a fixing plate 506 via a bearing. The fixing plate 506 is fixedly arranged on the rear end wall of the upper part of the protection box 1. The top of the second worm 505 is meshed with a second worm gear 507. The front end of the second worm gear 507 is fixedly connected to a third worm 508. One end of the third worm 508 is rotatably connected to the front end wall inside the protection box 1 via a bearing. A seventh runner 509 is arranged in front of the third worm 508. A transmission connection is formed between the seventh runner 509 and an eighth runner 511 via a fourth belt 510. The eighth runner 511 is rotatably connected to the front end wall on the right side inside the protection box 1 via a bearing. The rear end wall of the eighth runner 511 is fixedly connected to a fourth worm 512. The rear end of the fourth worm 512 is rotatably connected to a fixing seat 513 via a bearing. The fixing seat 513 is fixedly arranged at the rear of the top inside the protection box 1. A ninth runner 514 is arranged in the middle of the third worm 508. A tenth runner 516 is arranged in the middle of the first worm 306. A transmission connection is formed between the ninth runner 514 and the tenth runner 516 via a fifth belt 515. Two mounting columns 517 are rotatably connected to the upper sides on both sides inside the protection box 1 via bearings. Third worm gears 518 are arranged on the four mounting columns 517. The third worm 508 and the fourth worm 512 are respectively meshed with the four third worm gears 518. One end of each of the four mounting columns 517 is provided with a second fan 519. The four second fans 519 are symmetrically arranged.

[0037] As the third worm 508 rotates, its seventh runner 509 rotates. Through the transmission of the fourth belt 510, the eighth runner 511 rotates, and the fourth worm 512 rotates accordingly. Thus, the third worm 508 and the fourth worm 512 drive the four third worm gears 518 to rotate until the four second fans 519 rotate, facilitating the aggregation of iron slag and dust splashed during welding inside the middle of the protection box 1, facilitating the adsorption and collection work of the three first fans 304. Moreover, the rotation of the four second fans 519 can also timely blow the dust on the surface of the bath chair during the grinding after welding, facilitating subsequent painting treatment and improving the painting effect.

[0038] Working principle: When using welding, the bathing chair is placed on the processing table 2, and the external welding equipment performs welding work on it. During welding, the motor 311 is started simultaneously. The motor 311 drives the rotating shaft 312 to rotate, and the first runner 406 rotates accordingly. Through the transmission of the first belt 407, the second runner 408 rotates, and the third runner 410 rotates accordingly. Through the transmission of the second belt 411, the fourth runner 412 and the fifth runner 502 rotate. Through the transmission of the third belt 503, the sixth runner 504 rotates. The second worm 505 drives the second worm gear 507 to rotate, and the third worm 508 rotates. The ninth runner 514 rotates accordingly. Through the transmission of the fifth belt 515, the tenth runner 516 rotates, and then the first worm 306 drives three first worm gears 305 to rotate, thereby driving three first fans 304 to rotate, generating negative pressure to facilitate the adsorption of iron filings and dust generated during welding into the pipe body 301. Blocked by the partition 316, it enters the separation box 402 through the conveying pipe 401. As the third worm 508 rotates, the seventh runner 509 rotates. Through the transmission of the fourth belt 510, the eighth runner 511 rotates, and the fourth worm 512 rotates accordingly. Thus, the third worm 508 and the fourth worm 512 drive four third worm gears 518 to rotate until four second fans 519 rotate, facilitating the aggregation of iron slag and dust splashed during welding in the middle of the protective box 1, facilitating the adsorption and collection work of the three first fans 304. Moreover, the rotation of the four second fans 519 can also blow the dust on the surface of the bathing chair in time when grinding after welding is completed, facilitating subsequent painting treatment and improving the painting effect. When the rotating shaft 312 rotates, the disc 313 rotates, and the first connecting rod 314 and the second connecting rod 315 rotate accordingly, causing the sleeve plate 308 to move up and down under the guidance of the two first I-shaped members 307. Through the cooperation of the brush 309, the dust on the partition 316 can be timely processed into the separation box 402. In addition, the rotation of the third runner 410 and the fourth runner 412 causes the two shaft columns 413 to rotate, and the four cams 414 continuously touch the filter plate 404, causing the filter plate 404 to move up and down under the guidance of the four second I-shaped members 403. The four springs 405 are continuously stretched or compressed, facilitating the rapid separation of dust and iron slag. The separated iron slag is output from the discharge port 415 for recycling and reuse, and the dust is filtered to the lower part of the separation box 402 and output from the discharge pipe 416.
