Technical Field

[0001] The invention relates to the field of pad strip cutting, in particular to an automatic cutting device for insulating thin paperboard pad strips. Background Art

[0002] The pad is mainly made of 1.0mm thick paperboard, which is cut and processed according to different specifications. It is mainly used between the wire handles of transformer coils or on the inner and outer diameter sides of coils. Common pads include turn pads and inner diameter pads. Their main purpose is to adjust the amplitude phase and ampere-turn balance of the coil, and at the same time protect the wire. The width of the paper pad is related to the width of the wire. The number of paper pads required between turns is determined by the design and calculation of ampere-turn balance. At present, the processing of 1.0mm thin paperboard pads is usually carried out in a more traditional manual or semi-manual way. At the same time, the manual cutting method is prone to cause problems such as burrs and tears in the pads, inducing local electric field distortion, increasing the risk of corona discharge and even insulation breakdown, and affecting the insulation performance. With the rapid development of electrical equipment industries such as transformers, the quality requirements for thin paperboard pads are getting higher and higher. The trend of miniaturization and high performance of transformers requires higher dimensional accuracy and better insulation performance of the pads. Therefore, in order to improve production efficiency, reduce labor costs and ensure the stability of product quality, a special processing machine that can efficiently and accurately process 1.0mm thin cardboard pads is needed to meet the strict requirements of modern electrical equipment manufacturing industry for pad processing, thus promoting the production of patented technology for 1.0mm thin cardboard pad processing machine; The existing publication number is: CN118493491A, which is an automatic cutting machine, including a machine frame, a table plate is arranged on the machine frame, the table plate is divided into a first area and a second area, a first pad block and a second pad block are placed in a plurality of through grooves in the first area and the second area respectively, the bottom of the first pad block and the second pad block are synchronously moved in the lateral direction by a first moving mechanism and a second moving mechanism, the bottom of the first pad block and the second pad block are fixed to the first frame bar and the third frame bar respectively; the first pressure plate and the second pressure plate are arranged on the second frame bar and the fourth frame bar respectively, and the electric drive mechanism drives the first frame bar or the third frame bar to move in the lateral direction of the machine frame; the upper tool assembly and the lower tool assembly are arranged above and below the upper lateral frame of the machine frame respectively.

When the slider three slides at the angle position in the angled slide rail, the angled slide rail moves downward, and then drives the pressure plate fixedly connected to the angled slide rail to move downward, so as to press the pad. The angled design of the angled slide rail converts horizontal motion into vertical motion, reduces the length of the transmission chain, and avoids jamming. BRIEF DESCRIPTION OF THE DRAWINGS
