Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil heat sink processing, and particularly relates to a slitting mechanism for aluminum foil heat sink processing. Background Technique

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. Aluminum foil is a hot stamping material directly rolled from metallic aluminum into a thin sheet. Its hot stamping effect is similar to that of pure silver foil stamping, so it is also called false silver foil. The aluminum foil heat sink is an excellent heat sink. When producing and processing aluminum foil heat sinks, a corresponding production line is required, and a slitting mechanism is needed in one of the links to slit the aluminum foil.

[0003] Comparing with the Chinese patent with the authorization announcement number of CN220331370U, it discloses a cutting device for aluminum foil slitting with high cutting accuracy, including a mounting substrate. The number of the mounting substrates is two. A front positioning roller and a rear positioning roller are respectively movably installed on the front and rear sides of the surface of the mounting substrate. A displacement groove is horizontally penetrated and opened on the surface of the mounting substrate. An active guiding component is penetrated and installed in the inner cavity of the displacement groove. An adjustable cutting component is installed on the top of the surface of the mounting substrate. The adjustable cutting component includes a movable roller and a driving motor. A middle connecting component is arranged at the center of the adjustable cutting component.

[0004] When adjusting the position of the cutting wheel in the above patent, it is necessary to first loosen the fastening bolt, then slide to adjust the cutting position, and finally re-tighten the fastening bolt. The operation is cumbersome and the adjustment is inconvenient. Therefore, a new device needs to be designed. Content of the Utility Model

[0026] Please refer to Figures 1 - 5 , a slitting mechanism for processing aluminum foil radiators, including a support component for supporting the slitting of aluminum foil and adjusting the cutting depth by lifting, and further including a driving component installed at the middle position of the support component for driving rotation for slitting and supporting sliding adjustment. Six slitting components for rotating and slitting aluminum foil and helically pushing the slitting position adjustment are evenly arranged on the driving component.

[0027] In this embodiment: The support component includes two side plates 101 symmetrically arranged front and back. Two guide rollers 102 are symmetrically arranged on both sides between the two side plates 101. A support roller 103 is arranged above the guide rollers 102. A support plate 104 is arranged at the top of the side plate 101. An electric push rod 105 is installed on the support plate 104. The bottom of the electric push rod 105 is provided with a sliding carriage 106. The sliding carriage 106 is slidably connected to the side plate 101. The side plate 101 is made of 45# material, so that the aluminum foil passes under the guide roller 102 on one side, above the two support rollers 103, and under the guide roller 102 on the other side in sequence under the support of the side plate 101. Then, the support plate 104 supports the electric push rod 105 to extend and drive the driving component and the slitting component to move downward through the sliding carriage 106 to slit the aluminum foil;

[0028] In this embodiment: The driving component includes a rotating shaft 202. A motor 201 is installed at the front end of the rotating shaft 202. A cutter roller 203 is arranged outside the rotating shaft 202. A limiting groove 204 is formed in the cutter roller 203. A threaded bar 205 is arranged in the limiting groove 204. The threaded bar 205 is welded to the cutter roller 203. The motor 201 drives the rotating shaft 202 to rotate, so that the cutter roller 203 drives the cutting component to rotate through the limiting groove 204.

The fixing ring 307 is threadedly connected to the slip ring 301. When the slitting position needs to be adjusted, only the knob 304 needs to be rotated, so that the stud 302 is driven to rotate through the rotating rod 303, and the stud 302 meshes with the threaded bar 205 to push the slip ring 301 to drive the cutting disc 306 to slide along the cutter roller 203 to adjust the slitting position; When the fixing ring 307 is unscrewed, the cutting disc 306 can also be removed from the installation ring 305 for maintenance and replacement of the cutting disc 306.

[0030] Working principle: The aluminum foil is supported by the side plate 101 and passes under the guiding roller 102 on one side, above the two supporting rollers 103, and under the guiding roller 102 on the other side in sequence. Then, the motor 201 drives the rotating shaft 202 to rotate, so that the cutter roller 203 drives the slip ring 301 and the cutting disc 306 to rotate through the limiting groove 204. Then, the support plate 104 supports the electric push rod 105 to extend, driving the rotating shaft 202 to move downward through the sliding frame 106 to adjust the cutting depth, so that the rotating cutting disc 306 contacts and slits the aluminum foil; When the slitting position needs to be adjusted, only any one of the two knobs 304 needs to be rotated, so that the stud 302 is driven to rotate through the rotating rod 303, and the stud 302 meshes with the threaded bar 205 to push the slip ring 301 to drive the cutting disc 306 to slide along the cutter roller 203 to adjust the slitting position; When the fixing ring 307 is unscrewed, the cutting disc 306 can also be removed from the installation ring 305 for maintenance and replacement of the cutting disc 306.
