Description

Technical Field

[0001] The invention relates to the technical field of foam production, in particular to a continuous slitting device for foam production. Background Art

[0002] Foam is a material made by expanding plastic particles, often referred to as foam. It can be categorized into PU foam, anti-static foam, electric foam, EPE, anti-static EPE, CR, EVA, cross-linked PE, SBR, and EPDM. Foam offers a range of advantages, including elasticity, light weight, rapid pressure-sensitive fixation, ease of use, flexible bending, ultra-thin size, and reliable performance.

[0003] In the process of foam production, the corresponding foam needs to be cut. A Chinese patent (patent number CN215047462U) proposes a foam cutting device, including a workbench, an avoidance groove running through the workbench, a tool seat and a cutting knife arranged on the tool seat, a fixed column vertically provided on the tool seat, a flattening component for pressing the foam in the vertical direction is provided on the fixed column, and two flattening components are provided, and the two flattening components are symmetrically arranged on both sides of the length direction of the avoidance groove; the flattening component includes a connecting frame arranged on the fixed column, a slider arranged at the bottom end of the connecting frame, and a slider arranged at the bottom end of the slider. The patent comprises a linear guide rail with sliding fit and a pressing plate arranged on the bottom surface of the linear guide rail, the length direction of the pressing plate is parallel to the length direction of the avoidance groove. The patent uses a flattening component to flatten the foam during the cutting process to reduce the generation of wrinkles, which can effectively improve the cutting quality after the stacking of multiple layers of soft thin foam. However, such foam needs to be manually placed and supported during transportation and cutting, and the cutting step is carried out after the support is completed. Such a cutting device is not only time-consuming and labor-intensive, but also causes the foam cutting efficiency to decrease. For this reason, we propose a continuous cutting device for foam production. Summary of the Invention
