Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of color master batch cutting, especially relates to a color master batch underwater cutting cutter. BACKGROUND

[0002] The color master batch underwater cutting cutter is a key tool for the underwater cutting link in the color master batch production process, and plays a role in the process of cutting the material into particles for subsequent packaging and use after the material is extruded into a strip shape by an extruder. The cutter is generally installed in an underwater cutting machine and works underwater. The cutter usually has high hardness and wear resistance because it needs to frequently cut the color master batch material strip with certain toughness and hardness. The cutting edge of the cutter is designed to be relatively sharp, which can cleanly cut the material strip and minimize damage to the particle shape during cutting to ensure the size accuracy and appearance quality of the color master batch particles. At the same time, the cutter is usually made of a material with good corrosion resistance because it works underwater and is easily eroded by water. The appropriate material can prolong the service life of the cutter and ensure the efficient and stable operation of the color master batch underwater cutting work.

[0003] A color master batch underwater cutting cutter is disclosed in Chinese Patent No. CN218256088U, which includes a rotating rod, a buffer spring, a spring clamp, a buffer head, a cutting fixture, and a cutting device. The rotating rod is driven by a drive motor. The rotating rod is connected to the drive motor at one end and has a hexagonal slot at the other end. The buffer head is connected to the hexagonal slot at one end. The rotating rod surface at the other end of the hexagonal slot is provided with external threads. The spring clamp is rotatably connected to the rotating rod and engages with the external threads. The other end of the buffer head is fixedly connected to the cutting fixture. The cutting device is fixed to the cutting fixture. The utility model designs an underwater cutting cutter that cuts particles at high speed and effectively absorbs dust underwater. The cutter has a spring contraction effect and buffering property, which prevents the motor from being damaged and stopped, etc.

[0004] Although the above device has certain convenience and buffering performance during actual use, there are still some deficiencies in the specific use process. Overall, during the use of the device, the cutter is installed by bolts. Since the cutter will inevitably be damaged, broken or deformed during long-term use, the cutter must be disassembled and replaced after a period of use.
