Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, and more specifically, to a noise-reducing folding machine. Background Technology

[0002] A folding machine, also known as a book folding machine, is a modern printing equipment that emerged alongside the modern printing industry. Modern printing plants typically include three processing steps: pre-press, printing, and post-press. The primary medium is paper. Folding machines are mainly used for folding various sizes and thicknesses of paper within their design scope. For example, a noise-reducing folding machine disclosed in patent CN214827843U uses a scissor lift mechanism that moves up and down under the action of a buffer component when the folding machine body vibrates. This reduces the degree of collision between the folding machine body and other objects, improving the noise reduction effect of the folding machine body. At the same time, the folding machine body is equipped with a sound-absorbing component, which can absorb the noise generated during the operation of the conveying device and the folding device, further reducing noise.

[0003] When the above-mentioned device is in use, the combination of the scissor lift mechanism and the buffer assembly can effectively reduce the vibration and collision amplitude generated by the folding machine body during startup, reduce the noise generated by the folding machine body, and achieve the effect of reducing the noise of the folding machine body. However, the vibration generated by the folding machine is multi-angled, and the shock absorption effect of the scissor lift mechanism is limited. At the same time, the vibration generated by the folding machine will be directly transmitted to the buffer frame, which can easily generate greater noise and reduce the noise reduction effect of the folding machine.
