Description

Technical Field

[0001] The invention relates to the technical field of automobile muffler production and processing, and in particular to an automobile muffler pipe cleaning device. Background Art

[0002] Automobile mufflers are mainly used to reduce the noise of exhaust gas emitted by automobile engines. Automobile exhaust gas contains a large amount of harmful substances and heat. Therefore, the internal pipes of automobile mufflers are sprayed during the production and processing process. The corrosion-resistant coating is sprayed to increase its service life. In order to improve the adhesion of the coating, the pipes are cleaned before spraying;

[0003] For example, patent application number CN202310751185.9 discloses a muffler processing and cleaning device with high cleaning efficiency. The driving structure of the patent drives the rotating structure to rotate, thereby causing the rotating structure and the workbench to rotate, so that the muffler cooperates with the rotating structure for cleaning, thereby improving the cleaning efficiency; the setting of the fixed structure facilitates cleaning in cooperation with the rotating structure, and avoids the rolling of the muffler during cleaning, thereby improving practicality; the setting of the cleaning structure can clean the muffler, and drive the components in the rotating structure to rotate during cleaning, thereby achieving better cleaning effect; the setting of the installation structure facilitates the replacement of the cleaning components in the cleaning structure, thereby improving the installation efficiency of the cleaning components; the setting of the collection structure facilitates the collection of the cleaned muffler, thereby avoiding the cleaned muffler from falling from the workbench.

DETAILED DESCRIPTION

[0055] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] like Figure 1-13 In the first embodiment, a cleaning device for a car muffler pipe includes:

[0057] The cleaning box 100 has a drain pipe 110 at the bottom of one side wall;

[0058] A feed pipe 200, which passes through the upper end wall of the cleaning box 100 and penetrates the upper end wall;

[0059] A second conveyor belt 400, one end of which is disposed inside the cleaning box 100 and the other end of which is disposed outside the cleaning box 100;

[0060] The loading assembly 300 is disposed in the cleaning box 100;

[0061] The rotating plate 500 is rotatably disposed in the cleaning box 100;

[0062] A plurality of rotating plates 530 are rotatably disposed around the rotating plate 500;

[0063] A plurality of cleaning structures are respectively arranged on the rotating plate 530, and the feeding assembly 300 is used to deliver the muffler pipe into the cleaning structure;

[0064] The cleaning structure includes:

[0065] The positioning sleeve 600 is fixedly connected to the rotating plate 530;

[0066] A plurality of rotating sleeves 700 are rotatably disposed in 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 sleeves 600, and the first nozzles 610 are directly facing the gap between two adjacent rotating sleeves 700;

[0068] A plurality of iron plates 800 are arranged in a ring shape and are located inside the rotating sleeve 600. The iron plates 800 are fixedly connected to the rotating sleeve 600 via a second spring 820.

[0069] The annular electromagnet 830 is fixedly mounted on the outer wall of the positioning sleeve 600 and is used to adsorb the iron plate 800;

[0070] A plurality of first cleaning brushes 810 are detachably disposed on the side wall of the iron plate 800 opposite to the rotating sleeve 700;

[0071] The inner wall cleaning assembly 900 is disposed on the rotating plate 530 and is used to clean the inner wall of the muffler pipe. The inner wall cleaning assembly includes:

[0072] The rotating barrel 910 is rotatably disposed on the rotating plate 530;

[0073] A plurality of second spray heads 930 are respectively disposed on the rotating barrel 910 and are connected to the rotating barrel 910;

[0074] A plurality of second cleaning brushes 920 are detachably disposed on the outer side walls of the rotating barrel 910;

[0075] A plurality of universal ball seats 960 are fixedly connected to the outer surface of the rotating barrel 910 through support rods 961.

[0076] On the wall.

[0077] This embodiment is implemented as follows:

[0078] When the present application is in use, a worker places the muffler pipe fitting in the feed pipe 200, and the muffler pipe fitting falls onto the loading assembly 300, and then the annular electromagnet 830 is started, and the annular electromagnet 830 will adsorb the iron plate 800, so that the iron plate 800 moves toward the rotating sleeve 700, and the second spring 820 is compressed at this time, and then the muffler pipe fitting is sent to the cleaning structure through the loading assembly 300, that is, the muffler pipe fitting is sleeved outside the rotating barrel 910, and the muffler pipe fitting can be limited in its pressure effect on the bristles on the second cleaning brush 920 through the universal ball seat 960, and then the annular electromagnet 830 is closed, and under the recovery action of the second spring 820, the iron plate 800 returns to its original position, and at this time the bristles of the first cleaning brush 810 can contact the outer wall of the muffler pipe fitting, and then the rotating sleeve 700 rotates, the rotating barrel 910 rotates, the rotating sleeve 700 drives the first cleaning brush 810 to rotate, and the rotating barrel 910 The second cleaning brush 920 is driven to rotate. At the same time, the first nozzle 610 and the second nozzle 930 spray cleaning liquid. The cleaning liquid sprayed by the first nozzle 610 will pass through the gap between the two adjacent rotating sleeves 700 and spray on the surface of the iron plate 800 or the surface of the muffler pipe. The size of the iron plate 800 in the present application is relatively small, so the amount of cleaning liquid sprayed by the first nozzle 610 blocked by the iron plate 800 is small, so the spraying effect of the outer wall of the muffler pipe can be improved by increasing the spraying time; the second nozzle 930 can spray the inner wall of the muffler pipe; it should be noted that the rotation directions of the rotating sleeve 700 and the rotating barrel 910 in the present application are first opposite, then the same, and finally opposite again. The main reason is that the muffler pipe in the present application is not fixed when being cleaned. Therefore, the muffler pipe can be cleaned by repeatedly brushing in different directions to avoid the cleaning blind spot caused by the muffler pipe following the rotation;

[0079] After cleaning is completed, the rotating plate 500 rotates, driving the cleaned muffler pipe to move to the bottom, and then the rotating plate 530 rotates relative to the rotating plate 500, so that the positioning sleeve 600 is tilted. At this time, the annular electromagnet 830 is started again, so that the first cleaning brush 810 leaves the muffler pipe. At this time, the muffler pipe can fall on the second conveyor belt 400 and be sent out of the cleaning box 100.

[0080] The advantage of the present application over the prior art is that the inner wall and the outer wall of the muffler pipe can be automatically cleaned simultaneously.

[0081] See also Figure 2 , 3 , the feeding assembly 300 comprises:

[0082] The support plate 310 is fixedly connected to the inner wall of the cleaning box 100 at a position corresponding to the feeding pipe 200. The upper surface of the support plate 310 has a positioning groove 311 at a position corresponding to the feeding pipe 200, and the bottom of the positioning groove 311 has a sliding hole 312;

[0083] The first conveyor belt 320 is disposed in the cleaning box 100;

[0084] A plurality of positioning plates 331 are respectively fixedly connected to the surface of the first conveyor belt 320;

[0085] A plurality of push plates 330 are rotatably connected to a plurality of positioning plates 331;

[0086] A plurality of first springs 332 are respectively fixedly connected to the positioning plate 331 and fixedly connected to the push plate 330;

[0087] The first conveyor belt 320 provided in the present application can drive the positioning plate 331 to move, and the positioning plate 331 can drive the push plate 330 to move, and the movement of the push plate 330 can pass through the slide hole 312 into the positioning groove 311, so that the push plate 330 can push the muffler pipe to move in the positioning groove 311 during the horizontal movement. At this time, the center of the muffler pipe is on the same straight line as the center of the rotating barrel 910, so the muffler pipe can be sleeved on the outer periphery of the rotating barrel 910; and the first conveyor belt 320 will stop at this time. The push plate 330 will move to the position of the side wall of the positioning sleeve 600, which enables the push plate 330 to limit 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 over the positioning sleeve 600, the push plate 330 will rotate to its original position again under the action of the restoring force of the first spring 332.

[0089] The present application can drive the rotating barrel 910 to rotate through the positioning rod 952 by rotating the rotating column 950 on the rotating plate 530. Since the rotating ring 941 is fixed to the rotating plate 530 through the connecting rod 942, the rotating ring 941 does not rotate. At this time, the cover body 940 and the rotating column 950 can rotate relative to the outer circumferential wall and the inner circumferential wall of the rotating ring 941. Cleaning liquid can be injected into the cover body 940 through the liquid supply pipe 943, and the cleaning liquid enters the rotating barrel 910 and is sprayed out from the second nozzle 930.
