Description

Technical Field

[0001] The utility model relates to the technical field of metal rolling, in particular to a fire barrier roller pressing machine. Background Art

[0002] Flame arrester, also known as fire preventer, is mainly used to prevent external flames from entering equipment and pipelines containing flammable and explosive gases, or to prevent flames from spreading between equipment and pipelines. The flame arrester is composed of a flame arrester core, an outer shell and accessories. The flame arrester grid is the core component of the flame arrester. Its quality directly affects the flame retardant effect and pressure loss of the flame arrester. The flame arrester grid needs to be produced using a roller pressing machine.

[0003] Patent document CN219745834U in my country discloses a fire barrier roller pressing machine. When the mounting block and motor 2 need to be disassembled, the user pulls down the circular plate to disengage the positioning rod from the positioning groove on the mounting block. At this time, the mounting block is unobstructed and the mounting block can be moved outward to remove the mounting block and motor 2, making it easier to disassemble, repair or replace motor 2, making it more convenient to use.

[0004] The above-mentioned utility model limits the position of the motor 2 by means of a positioning rod that movably passes through the support plate and is movably inserted into the positioning groove. However, this method only provides a simple limit to the motor 2, and the limiting location is at the lower side, while the output end of the motor 2 is at the upper position. In the absence of a clamping limit for the mounting block, the motor 2 will vibrate significantly during operation, and the noise generated by this significant vibration will also exceed the permitted specified range. This vibration will also affect the connection between the insert block and the mounting groove, thereby affecting the operation of the roller pressing machine. Utility Model Content
