Description

Technical Field

[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. It is a special equipment for paper, board and film mounting. After being pressurized by rubber rollers and heating rollers, they are combined to form a paper-plastic product. It is indispensable for the raw materials of film for film mounting. When the film is pulled out from the mother roll and wrapped around another roller, it is easy to generate noise pollution of up to 100 decibels at the moment of tearing off the tape. When the noise reaches more than 80 decibels, it is easy to cause great trouble to users and even affect the working environment of the workshop.

[0003] In the prior art, in order to reduce the noise generated when the tape is pulled out from the mother roll, the user chooses to slow down the time of pulling out the tape.

When the pressure pump needs to reduce noise during operation, the pressure pump drives the first horizontal plate to move downward, the first horizontal plate drives the second horizontal plate to move, the second horizontal plate drives the four second round rods to move, and when the second horizontal plate moves, it also drives the buffer spring to move;
