TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting device for heat-conducting adhesive tape production, in particular to a positioning cutting device for heat-conducting adhesive tape production. BACKGROUND

[0002] The heat-conducting adhesive tape is made of acrylic polymer and silica gel, and has high bonding strength and excellent heat-conducting performance. The heat-conducting adhesive tape can be used to bond and fix the device and the heat sink, realize heat conduction, insulation and fixation, and is widely used in the bonding between the power device and the heat sink. The heat-conducting adhesive tape can realize heat conduction, insulation and fixation, and effectively reduce the size of the equipment, which is a favorable choice for reducing the cost of the equipment.

[0003] In the production process of the heat-conducting adhesive tape, the heat-conducting adhesive tape needs to be wound on a hard paper tube for shaping into a master roll, and then the master roll is cut by a cutter to finally become a heat-conducting adhesive tape roll. Therefore, a cutting machine is needed.

[0004] In the existing cutting machine, when the heat-conducting adhesive tape placed in the cutting machine rotates at a high speed, the winding roller will shake and easily deviate from the position, causing the heat-conducting adhesive tape to fall and deviate, which affects the cutting effect of the adhesive tape. In addition, the heat-conducting adhesive tape is prone to wrinkling during winding, which causes the adhesive tape to break due to excessive tension, and the cutting position is not smooth. Therefore, the positioning cutting device for heat-conducting adhesive tape production is proposed to solve the above problems. SUMMARY
