Description
Technical Field
[0001] This invention relates to the technical field of automobile muffler manufacturing and processing, and particularly to an automobile muffler pipe cleaning device. Background Technology
[0002] Automotive mufflers are mainly used to reduce noise from the exhaust gases emitted by car engines. Since car exhaust gases contain a large number of harmful substances and heat, the internal pipes of automotive mufflers are coated during the manufacturing process. A corrosion-resistant coating is applied to increase their service life. In order to improve the adhesion of the coating, the pipes are cleaned before coating.
[0003] For example, patent application number CN202310751185.9 discloses a high-efficiency muffler processing and cleaning device. This patent's drive structure drives the rotating structure to rotate, thereby causing the rotating structure to rotate with the worktable, thus enabling the muffler to be cleaned in conjunction with the rotating structure, improving cleaning efficiency. The fixed structure facilitates cleaning in conjunction with the rotating structure and prevents the muffler from rolling during cleaning, improving practicality. The cleaning structure can clean the muffler and drives the components in the rotating structure to rotate during cleaning, resulting in better cleaning effect. The installation structure facilitates the replacement of the cleaning components in the cleaning structure, thereby improving the installation efficiency of the cleaning components. The collection structure facilitates the collection of the cleaned muffler, preventing the cleaned muffler from falling off the worktable.
[0004] However, the existing patented technology can only clean the outer wall of the muffler when cleaning the muffler pipes. In actual use, both the inner and outer walls of the muffler pipes will come into contact with the exhaust gas and need to be sprayed. Therefore, this method of cleaning the outer wall first and then cleaning the inner wall is inefficient. At the same time, the existing cleaning method requires workers to connect the pipes to the connecting column one by one, which is a very troublesome loading method. Summary of the Invention

Detailed Implementation
[0055] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0056] like Figure 1-13 In this first embodiment, a car muffler pipe cleaning device includes:
[0057] The cleaning box 100 has a drain pipe 110 at the bottom of one side wall;
[0058] The feed pipe 200 penetrates the upper wall of the cleaning box 100 and extends through the upper wall.
[0059] The second conveyor belt 400 has one end located inside the cleaning box 100 and the other end located outside the cleaning box 100;
[0060] The feeding component 300 is installed inside the cleaning box 100;
[0061] The rotating plate 500 is rotatably installed inside the cleaning box 100;
[0062] Several rotating plates 530 are rotatably arranged around the rotating plate 500;
[0063] Several cleaning structures are respectively set on the rotating plate 530, and the feeding assembly 300 is used to send the silencer pipes into the cleaning structures.
[0064] The cleaning structure includes:
[0065] The positioning sleeve 600 is fixedly connected to the rotating plate 530;
[0066] Several rotating sleeves 700 are rotatably disposed within the positioning sleeve 600, and two adjacent rotating sleeves 700 are fixedly connected by a connecting rod 701.
[0067] A plurality of first nozzles 610 are respectively disposed in the positioning holes 611 of the positioning sleeve 600, and the first nozzle 610 is directly opposite the gap between two adjacent rotating sleeves 700.
[0068] Several iron plates 800 are arranged in a ring and located inside the rotating sleeve 600. The iron plates 800 and the rotating sleeve 600 are fixedly connected by a second spring 820.
[0069] A ring electromagnet 830 is fixedly sleeved on the outer wall of the positioning sleeve 600 and is used to attract the iron plate 800.
[0070] Several first cleaning brushes 810 are detachably mounted on the side wall of the iron plate 800 opposite to the rotating sleeve 700.
[0071] An inner wall cleaning assembly 900, mounted on a rotating plate 530, is used to clean the inner wall of the muffler fittings; the inner wall cleaning assembly includes:
[0072] The rotating barrel 910 is rotatably mounted on the rotating plate 530;
[0073] Several second nozzles 930 are respectively disposed on the rotating barrel 910 and connected to the rotating barrel 910;
[0074] Several second cleaning brushes 920 are detachably mounted on the outer wall of the rotating drum 910;
[0075] Several universal ball joints 960 are fixedly connected to the outside of the rotating barrel 910 via support rods 961.
[0076] On the wall.
[0077] This embodiment is implemented as follows:
[0078] In use, the worker places the muffler fitting into the feed pipe 200, and the muffler fitting falls onto the feeding assembly 300. Then, the annular electromagnet 830 is activated, attracting the iron plate 800, causing the iron plate 800 to move towards the rotating sleeve 700. At this time, the second spring 820 is compressed, and then the muffler fitting is sent to the cleaning structure through the feeding assembly 300, that is, the muffler fitting is placed over the rotating drum 910. The universal ball joint 960 limits the pressure exerted by the muffler fitting on the bristles of the second cleaning brush 920. Then, the annular electromagnet 830 is deactivated, and under the restoring action of the second spring 820, the iron plate 800 returns to its original position. At this time, the bristles of the first cleaning brush 810 can contact the outer wall of the muffler fitting. Then, the rotating sleeve 700 rotates, the rotating drum 910 rotates, and the rotating sleeve 700 drives the first cleaning brush 810 to rotate. The second cleaning brush 920 is rotated, and at the same time, the first nozzle 610 and the second nozzle 930 spray cleaning fluid. The cleaning fluid sprayed by the first nozzle 610 passes through the gap between the two adjacent rotating sleeves 700 and sprays onto the surface of the iron plate 800 or the surface of the muffler pipe. The size of the iron plate 800 in this application is relatively small, so the amount of cleaning fluid sprayed by the first nozzle 610 is blocked by the iron plate 800. Therefore, by increasing the spraying time, the spraying effect on the outer wall of the muffler pipe can be improved. The second nozzle 930 can spray the inner wall of the muffler pipe. It should be noted that in this application, the rotation direction of the rotating sleeve 700 and the rotating barrel 910 is first opposite, then the same, and finally opposite again. The main reason is that the muffler pipe is not fixed when being cleaned. Therefore, by repeatedly brushing in different directions, the muffler pipe can be cleaned and the cleaning blind spots caused by the rotation of the muffler pipe can be avoided.
[0079] After cleaning, the rotating plate 500 rotates, moving the cleaned muffler pipe to the bottom. Then, the rotating plate 530 rotates relative to the rotating plate 500, causing the positioning sleeve 600 to tilt. At this time, the annular electromagnet 830 is activated again, causing the first cleaning brush 810 to leave the muffler pipe. The muffler pipe can then fall onto the second conveyor belt 400 and be sent out of the cleaning box 100.
[0080] The advantage of this application over the prior art is that it can automatically clean both the inner and outer walls of the muffler fittings simultaneously.
[0081] Please see Figure 2 , 3 The feeding assembly 300 includes:
[0082] The support plate 310 is fixedly connected to the inner wall of the cleaning box 100 at the position corresponding to the feed pipe 200. The upper surface of the support plate 310 has a positioning groove 311 at the position corresponding to the feed pipe 200, and the bottom of the positioning groove 311 has a sliding hole 312.
[0083] The first conveyor belt 320 is installed inside the cleaning box 100;
[0084] Several positioning plates 331 are respectively fixedly connected to the surface of the first conveyor belt 320;
[0085] Several push plates 330 are rotatably connected to several positioning plates 331 respectively;
[0086] Several first springs 332 are respectively fixedly connected to the positioning plate 331 and fixedly connected to the push plate 330;
[0087] This application utilizes a first conveyor belt 320 to move a positioning plate 331, which in turn moves a push plate 330. The push plate 330 moves through a sliding hole 312 into a positioning groove 311, allowing it to push the muffler fitting within the positioning groove 311 during horizontal movement. At this point, the center of the muffler fitting is aligned with the center of the rotating drum 910, allowing the muffler fitting to fit around the rotating drum 910. The first conveyor belt 320 then stops. The push plate 330 will move to the side wall of the positioning sleeve 600, which allows the push plate 330 to restrict the position of the muffler pipe, thereby preventing the muffler pipe from moving out of the range of the positioning sleeve 600. When the first conveyor belt 320 continues to start, the push plate 330 will rotate relative to the positioning plate 331 under the obstruction of the positioning sleeve 600. At this time, the first spring 332 will be compressed. When the push plate 330 passes the positioning sleeve 600, under the restoring force of the first spring 332, the push plate 330 will rotate back to the original position.
[0088] Please see Figure 2 , 5 6, 7, 8, 9, The opening end of the rotating barrel 910 is fixedly connected to a cover 940 and communicates with the cover 940. The opening end of the cover 940 is rotatably connected to an annular rotating ring 941. The rotating ring 941 is fixedly connected to the rotating plate 530 through a connecting rod 942. A rotating column 950 is rotatably connected to the inner wall of the rotating ring 941. The rotating column 950 is fixedly connected to the inner wall of the rotating barrel 910 through a positioning rod 952. The rotating ring 941 has a liquid supply pipe 943 that communicates with the cover 940. The rotating column 950 is rotatably mounted on the rotating plate 530.
[0089] This application enables the rotating column 950 to rotate on the rotating plate 530, which in turn drives the rotating barrel 910 to rotate via the positioning rod 952. Since the rotating ring 941 is fixed on the rotating plate 530 via the connecting rod 942, the rotating ring 941 does not rotate. At this time, the cover 940 and the rotating column 950 can rotate relative to the outer and inner circumferential walls of the rotating ring 941. Cleaning liquid can be injected into the cover 940 through the liquid supply pipe 943. The cleaning liquid enters the rotating barrel 910 and is sprayed out from the second nozzle 930.
[0090] Please see Figure 2 , 4 5, 6, 7, A second drive motor 951 is fixedly connected to the rotating plate 530, and the output end of the second drive motor 951 is fixedly connected to the rotating column 950;
[0091] The second drive motor 951 can drive the rotating column 950 to rotate on the rotating plate 530.
[0092] Please see Figure 2 , 4 5, 6, 7, 10, 11, the inner circumferential wall of the positioning sleeve 600 has a rotating groove 601, the rotating sleeve 700 is rotatably disposed in the rotating groove 601, and the positioning sleeve 600 has a number of driving components for driving the rotating sleeve 700 to rotate.
[0093] By providing a rotating groove 601 on the inner wall of the positioning sleeve 600, the rotating sleeve 700 can rotate within the rotating groove 601, and the rotating sleeve 700 can be driven to rotate by a driving component.
[0094] Please see Figure 2 , 4 5, 6, 7, 10, 11, the drive assembly includes an inner groove 711 disposed on the inner wall of the rotating groove 601 and an mounting plate 731 disposed on the outer wall of the positioning sleeve 600. A toothed ring 710 is fixedly sleeved on the outer wall of the rotating sleeve 700. The toothed ring 710 is located in the inner groove 711. The inner wall of the inner groove 711 has a through hole 721 that penetrates the positioning sleeve 600. A first drive motor 730 is fixedly connected to the mounting plate 731. A gear 720 is fixedly connected to the output end of the first drive motor 730. The gear 720 penetrates the through hole 721 and meshes with the toothed ring 710. The mounting plate 731 has a first waterproof cover 732 that protects the first drive motor 730.
[0095] The first drive motor 730 can drive the gear 720 to rotate, the gear 720 can drive the gear ring 710 to rotate, and the gear ring 710 can drive the rotating sleeve 700 to rotate.
[0096] Please see Figure 2 , 45. A rotating cylinder 531 is rotatably connected to each rotating plate 530 on the rotating plate 500, and the output end of the rotating cylinder 531 is rotatably connected to the rotating plate 530 at the corresponding position.
[0097] The rotating cylinder 531 can drive the rotating plate 530 to rotate on the rotating plate 500.
[0098] Please see Figure 2 , 4 5. A positioning cover 510 is fixedly connected to the inner wall of the cleaning box 100. A servo motor 520 is fixedly connected inside the positioning cover 510. The output end of the servo motor 520 is fixedly connected to the rotating plate 500.
[0099] The servo motor 520 can drive the rotating plate 500 to rotate on the positioning cover 510 inside the cleaning box 100.
[0100] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
