Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production technology, and more specifically, to a cutting device for plastic sheet production. Background Technology

[0002] Cutting equipment for plastic sheet production is one of the most important pieces of equipment in the plastics processing industry, used to meet the cutting needs of different plastic sheets.

[0003] When plastic sheets are rolled up, they are cut into different sizes according to usage requirements. Therefore, it is necessary to roll up the sheets cut from both sides. Existing cutting devices are usually equipped with automatic winding devices. However, although the distance between the two automatic winding devices can be adjusted according to the width of the sheet cut, the winding devices need to be operated separately during the adjustment process, which increases the complexity of equipment operation. To address this, we propose a cutting device for plastic sheet production. Utility Model Content

[0004] Based on the aforementioned issue regarding the cutting of plastic sheets into different sizes according to usage requirements during winding, it is necessary to wind up the sheets cut from both sides. Existing cutting devices are usually equipped with automatic winding devices. However, although the distance between the two automatic winding devices can be adjusted according to the width of the sheet cut, this adjustment process requires operating the winding devices separately, increasing the complexity of equipment operation. Therefore, this utility model proposes a cutting device for plastic sheet production.
