Problems solved by technology

[0002] At present, synthetic leather such as PVC or PU leather is used in the production of sofas, clothing, etc., but the breathability of synthetic leather is relatively poor. Holes are often formed on synthetic leather by punching to achieve air permeability. However, the holes formed in this way have a large diameter. After the punching is completed, a protective layer needs to be added, otherwise water will seep, and the protective layer The setting will reduce the breathability effect, resulting in poor breathability of synthetic leather; without a protective layer, the synthetic leather is prone to water seepage and poor waterproof performance

Abstract

The invention discloses a synthetic leather punching device. The synthetic leather punching device comprises a first tensioning roller assembly, a needle inserting assembly a second tensioning rollerassembly which are arranged in sequence; the needle inserting assembly comprises a first support, a heating roller and a cooling roller; the heating roller is pivoted to the first support, and a plurality of needles are fixed; and the cooling roller is pivoted to the first support, and a processing channel for allowing synthetic leather to penetrate is formed between the cooling roller and the heating roller. The invention further discloses a synthetic leather punching process. According to the synthetic leather punching device and the synthetic leather punching process, the synthetic leatherhas good air permeability and moisture-proof effects.

Description

technical field [0001] The invention relates to the field of synthetic leather processing, in particular to a synthetic leather punching device and a punching process. Background technique [0002] At present, synthetic leather such as PVC or PU leather is used in the production of sofas, clothing, etc., but the breathability of synthetic leather is relatively poor. Holes are often formed on synthetic leather by punching to achieve air permeability. However, the holes formed in this way have a large diameter. After the punching is completed, a protective layer needs to be added, otherwise water will seep, and the protective layer The setting will reduce the breathability effect, resulting in poor breathability of synthetic leather; without a protective layer, the synthetic leather is prone to water seepage and poor waterproof performance. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, one of the purposes of the present invention...
