Automatic cutting forming machine for hard carbon felt

Abstract

The invention discloses an automatic cutting forming machine for a hard carbon felt. The automatic cutting forming machine comprises a top plate, a cutting mechanism, a pressing mechanism and a spreading mechanism, supporting legs are arranged at corners of the bottom surface of the top plate, a cutting hole is formed in one side of the top plate along the width direction of the top plate, the cutting mechanism is arranged below the top plate, a cutting wheel in the cutting mechanism moves in the cutting hole to cut the carbon felt, the pressing mechanism comprises a pressing plate and a driving unit, the pressing plate is parallelly arranged on the top plate, the driving unit drives the pressing plate to vertically move, the pressing plate is arranged along the width direction of the topplate, the spreading mechanism two lead screws, a first motor, mounting blocks and a spreading unit, the lead screws are parallelly arranged along the length direction of the top plate, the first motor drives the lead screws to rotate, the mounting blocks are spirally connected on the lead screws in a sleeving manner, the spreading unit is arranged between the two mounting blocks, the lead screwsare parallel to the top plate, the first motor is fixed onto the top surface of the top plate, and the mounting blocks are slidably connected with the top plate. According to the automatic cutting forming machine, the carbon felt is conveniently and closely pressed, and the automatic cutting forming machine is high in cutting accuracy and simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of carbon felt, in particular to an automatic cutting and forming machine for hard carbon felt. Background technique [0002] At present, with the continuous development and growth of the semiconductor and solar energy industries, the demand for silicon materials is increasing. Monocrystalline silicon ingot is the raw material for manufacturing monocrystalline silicon solar cells. There are many methods for preparing monocrystalline silicon ingots. The Czochralski method is the most commonly used method in the field of silicon ingot manufacturing. It is to put processed high-purity polycrystalline silicon or defective silicon produced by the semiconductor industry into the quartz crucible of the single crystal furnace. , in a reasonable thermal field, heat the silicon under vacuum or atmosphere to melt it, use a processed seed crystal to fully weld it with the molten silicon, and rotate it at a certain spee...

Problems solved by technology

Existing carbon felt materials are usually sold in bundles, and the width of the carbon felt is greater than the height of the quartz crucible. Therefore, when buying back the bundled carbon felt coils, it needs to be manually cut and then wrapped outside the quartz crucible. Carbon felt has a porous structure, and if you don’t pay attention to it during the manual cutting process, it will be cut unevenly, which will cause waste of the entire roll of carbon felt, and the manual cutting precision is low and the workload is large. Automatic cutting and forming machine for carbon felt to solve the above problems
