Embodiment 1

[0034] This embodiment provides a thermally conductive film rewinder, such as figure 1 As shown, it includes a discharging shaft 1, a rewinding shaft 3, and two suction components 4.

[0035] Wherein, the unwinding shaft 1 is parallel to the axis of the rewinding shaft 3 and is arranged at a certain interval. The unwinding shaft 1 is suitable for covering the thermally conductive film roll to be rewinded; The heat-conducting film drawn from the shaft 1 is wound on its outer wall; the rewinding shaft 3 is driven to rotate by the driver to drive the unwinding shaft 1 to rotate. For example, the motor drives the winding shaft 3 to rotate, and the winding shaft 3 drives the unwinding shaft 1 to rotate synchronously with it through the transition effect of the thermally conductive film.

[0036] At least one suction assembly 4 is arranged between the unwinding shaft 1 and the rewinding shaft 3. The suction assembly 4 has at least one suction opening; the suction assembly 4 is used to g...

Abstract

The invention discloses a rewinding machine for a heat conduction film. The rewinding machine for the heat conduction film comprises at least one discharging shaft, a winding shaft and at least one suction assembly. The suction assembly is provided with at least one suction port. When the suction assembly works, the suction port faces the surface of one side of the heat conduction film located between the discharging shaft and the winding shaft. In the rewinding process, the discharging shaft is sleeved with the heat conduction film, and the heat conduction film pulled out of the discharging shaft is wound on the winding shaft; since the suction port faces the surface of one side of the heat conduction film when the suction assembly works, under the suction effect of negative pressure, scraps and solid foreign matter on the surface of the side of the heat conduction film are sucked into the suction assembly through the suction port, so that the scraps and solid foreign matter on the surface of the heat conduction film are reduced and even completely avoided, and thus, the appearance and performance of the heat conduction film meet requirements after the heat conduction film is calendered in the subsequent stage.

Description

Technical field [0001] The invention belongs to the technical field of thermally conductive graphite film rewinder, and specifically relates to a thermally conductive film rewinder. Background technique [0002] Thermally conductive graphite film is a new type of thermally conductive and heat-dissipating material, also known as thermally conductive graphite sheet, heat-dissipating graphite film, graphite heat-dissipating film, heat-conducting film, etc. The thermal conductive graphite film has a very obvious effect of heat conduction and heat dissipation. It can be combined with PET thermal film or double-sided tape according to the purpose, and can be bent multiple times, cut and stamped into any shape to meet more design requirements. It is used in electronics, communications, aviation and Many fields such as national defense and military industry have been widely used. [0003] Thermally conductive graphite film rolls are made by high-temperature sintering of the raw material p...
