Description

[Technical field]

[0001] The utility model relates to the technical field of cutting equipment, in particular to a wire roller and a slicer. [Background technology]

[0002] At present, in order to improve the efficiency of cutting operations for semiconductor silicon carbide, photovoltaic crystals, gemstones, etc., multi-wire cutting technology is usually used. The principle of multi-wire cutting technology is: a high-speed moving diamond wire drives the cutting blade attached to the diamond wire to rub against hard and brittle materials such as semiconductor silicon carbide, photovoltaic crystals, gemstones, etc., so as to achieve the purpose of cutting.

[0003] The wire roller is an indispensable component for the high-speed operation of the diamond wire. In order to drive the wire roller to rotate at high speed, the prior art adopts connecting the motor to the wire roller through a coupling. For example, the Chinese invention patent application with application number CN202211223467.3 discloses a diamond wire slicer for cutting crystalline silicon rods, which connects the cutting wire roller to the motor through a coupling. However, the existing wire roller has the following defects in actual use: 1. The motor is arranged at one end of the wire roller through a coupling, which makes it difficult to ensure concentricity, which is not conducive to the high-speed rotation of the wire roller, and the vibration amplitude of the wire roller is large during operation, which will affect the cutting effect; 2. When the wire roller is damaged, the entire wire roller needs to be disassembled and replaced, which is inconvenient to operate. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on the problem, and thus this case came into being. [Utility Model Content]
