AI Technical Summary
Existing waterproof membrane cutting equipment is bulky and complex, making it difficult to meet the flexible and convenient cutting needs in confined spaces or when construction sites change frequently. It is especially inconvenient to carry in small-scale construction scenarios.
A cutting device comprising a frame, a cutter, a control shaft, a synchronizing rod, and a linkage assembly was designed. The synchronous movement of the cutter is achieved through simple mechanical transmission. The cutter and the linkage are detachably connected and equipped with a torsion spring for automatic reset. The frame is equipped with a cutting groove and an anti-detachment component to facilitate the positioning and limiting of the waterproof roll material. Lightweight alloy materials are used to reduce the weight of the equipment.
The equipment features a simple and portable structure, easy-to-maintain cutter, and convenient cutting operation. It is suitable for the rapid cutting of small quantities of waterproof membrane, meets flexible construction needs, and improves cutting efficiency and equipment lifespan.
