Description

Technical Field

[0001] This utility model relates to the field of muffler processing technology, and in particular to a non-marking rolling device for muffler processing. Background Technology

[0002] In the production process of silencers, metal sheets need to be rolled into a cylindrical shape for use as the main body of the silencer. Existing rolling equipment bends the metal sheets during processing to make them conform to the cylindrical shape. This results in marks on the surface of the metal sheets due to bending, which is not only unsightly but also prone to misalignment during feeding, leading to a decrease in the quality of the bending.

[0003] The prior art CN221362075U discloses a novel non-marking rolling device for muffler processing, including a mounting plate. Side plates are provided on both sides of the top of the mounting plate, and a connecting plate is provided on one side of each side plate. The sheet metal is fed through the cooperation of a fixed roller, a drive roller, and a rotating roller. The drive roller, driven by a first motor, can transport the sheet metal to complete the rolling process. During the rolling process, a third motor drives a threaded rod to rotate. The threaded rod drives a mounting block via a second moving block, which in turn drives a grinding rod to descend. The grinding rod descends to the surface of the sheet metal, where it grinds the surface of the sheet metal during rolling and smooths out any marks caused by bending, thereby improving the quality and aesthetics of the rolled sheet metal. Furthermore, the grinding rod can be adjusted in real time according to the thickness of the sheet metal, facilitating the grinding of sheets of different thicknesses and improving the overall performance of the equipment.

[0004] However, the above structure generates a large amount of iron filings and dust during the grinding process of the muffler, which pollutes the processing environment and harms the health of the workers. Utility Model Content

[0023] This utility model provides a non-marking rolling device for muffler processing, including a base 101, a rolling assembly, two cylinders 102, a mounting frame 103, a grinding roller 104, an air extraction assembly, a connecting pipe 105, multiple connecting branch pipes 106, multiple adsorption bends 107, and multiple filter screens 108. The air extraction assembly includes a collection box 109, an air pump 110, and a protective cover 111. The rolling assembly includes a drive roller 112, a driven roller 113, and two adjusting rollers 114.

The limiting component includes a mounting cylinder 118, a bolt 119, a baffle 120, and a spring 121. The above structure solves the problem that a large amount of iron filings and dust are generated during the grinding of mufflers, polluting the processing environment and posing a threat to the health of workers.

[0024] In a specific embodiment, the roller assembly is disposed within the base 101, two cylinders 102 are mounted opposite each other on the base 101, and the output ends of the two cylinders 102 penetrate the base 101. The mounting bracket 103 is mounted on the output ends of the two cylinders 102. The grinding roller 104 is fixedly connected to the mounting bracket 103. The suction assembly and the connecting pipe 105 are respectively mounted above the base 101, and the suction assembly and the connecting pipe 105 are interconnected. One end of each of the plurality of connecting branch pipes 106 is connected to the connecting pipe 105, and the other end of each of the plurality of connecting branch pipes 106 penetrates the base 101 and is connected to each of the plurality of adsorption bends 107. A plurality of filter screens 108 are respectively disposed within the plurality of adsorption bends 107. In use, the metal plate is placed... Within the aforementioned drum assembly, the drum assembly operates to wind the metal plate. After winding, the two cylinders 102 operate, driving the grinding roller 104 to move vertically downwards, close to the drum. The drum assembly drives the drum to rotate, and the grinding roller 104 grinds the drum. Simultaneously, the extraction assembly operates, generating suction to adsorb the dust and debris generated during the grinding process. The dust and debris are transported to the extraction assembly through the inside of the adsorption bend 107, multiple connecting branch pipes 106, and connecting pipe 105. Further, when the dust and debris pass through the filter screen 108, the filter screen 108 filters the dust and debris, preventing larger particles from clogging the pipes and affecting subsequent processing. This solves the problem that a large amount of iron filings and dust are generated during the grinding of the muffler, polluting the processing environment and posing a health hazard to workers.

[0025] The collection box 109 is connected to the connecting pipe 105. The vacuum pump 110 is installed inside the collection box 109. The protective cover 111 is installed on the outer wall of the vacuum pump 110. When the grinding roller 104 grinds the drum, the vacuum pump 110 operates and generates suction. Dust and debris are transported to the collection box 109 through the adsorption bend 107, multiple connecting branch pipes 106 and the interior of the connecting pipe 105, facilitating subsequent centralized cleaning. The protective cover 111 protects the vacuum pump 110 to prevent dust and debris from entering the vacuum pump 110 and affecting its normal operation.

[0026] The drive roller 112 has a drive source 122 connected to one end, and a rotating seat 125 mounted on the other end. The rotating seat 125 is connected to a connecting assembly. The driven roller 113 is mounted below the drive roller 112, and both ends of the driven roller 113 are equipped with lifting cylinders 123. Two adjusting rollers 114 are respectively mounted on both sides of the drive roller 112, and both ends of the two adjusting rollers 114 are equipped with adjusting cylinders 124. During winding, the lifting cylinders 123 drive the driven roller 113 to move closer to the drive roller 112. The drive roller 112 and the driven roller 113 cooperate with each other to clamp the metal plate. The adjusting cylinder 124 drives the two adjusting rollers 114 to move along an oblique line. By adjusting the distance between them and the drive roller 112, the bending radius of the metal plate is changed. The drive source 122 operates, driving the drive roller 112 to rotate, and cooperates with the driven roller 113 and the adjusting rollers 114 to roll the metal plate into a roll, realizing the rolling of different diameters. After the roll is completed, the user can take out the roll by adjusting the connecting assembly.

[0027] The fixing plate 115 is fixedly connected to the base 101. The mounting rod 116 is installed above the fixing plate 115 and has a limiting hole. The sliding rod 117 is slidably disposed within the mounting rod 116 and has an insertion hole. The limiting member is disposed on the outer side wall of the mounting rod 116. After the drum is completed, the lifting cylinder 123 drives the driven roller 113 away from the driving roller 112, moving the drum toward the fixing plate 115. When the drum is in the position of the base 101, the limiting member is positioned above the base 115. When the mounting rod 116 and the sliding rod 117 are in position, the adjusting cylinder 124 drives the two adjusting rollers 114 to contact the driving roller 112, supporting the driving roller 112, pulling the limiting member, and sliding the sliding rod 117 so that the sliding rod 117 disengages from the rotating seat 125 and enters the mounting rod 116. At this time, the user can take out the drum. Furthermore, the limiting member can also limit the sliding rod 117 to prevent the sliding rod 117 from displacing and affecting the support of the driving roller 112.

[0028] The mounting cylinder 118 is fixedly connected to the mounting rod 116 and located on the outer side wall of the mounting rod 116.

The spring 121 is sleeved on the outer side wall of the plug 119. When the plug 119 is pulled, the spring 121 contracts. After the plug 119 disengages from the limiting hole and the insertion hole, the slide rod 117 can slide along the mounting rod 116. When the slide rod 117 is fixed, the plug 119 is released. The spring 121 pushes the baffle 120, thereby pushing the plug 119 to re-insert into the limiting hole and the insertion hole, thus fixing the slide rod 117.

[0029] When using the non-marking rolling device for muffler processing according to this utility model, a metal plate is placed between the drive roller 112 and the driven roller 113. The lifting cylinder 123 operates, clamping the metal plate through the driven roller 113 and the drive roller 112. The adjusting cylinder 124 drives the two adjusting rollers 114 to adjust the metal plate. The drive source 122 operates, driving the drive roller 112 to rotate, cooperating with the driven roller 113 and the two adjusting rollers 114 to roll the metal plate. After rolling, the two cylinders 102 operate, causing the grinding roller 104 to contact the rolling drum. The drive roller 112 rotates, and the grinding roller 104... The grinding roller 104 polishes and removes scratches from the drum. At the same time, the vacuum pump 110 operates, generating suction. Dust and debris are transported to the collection box 109 through the adsorption bend 107, multiple connecting branch pipes 106, and connecting pipe 105 for easy subsequent centralized cleaning. After processing, the driven roller 113 resets, and the two adjusting rollers 114 support the drive roller 112, pulling the plug 119 to slide the slide bar 117 into the mounting rod 116. At this point, the user can remove the drum. This solves the problem of generating a large amount of iron filings and dust during the grinding of the muffler, polluting the processing environment and posing a health hazard to workers.
