Description

Technical Field

[0001] The present application relates to the technical field of waterproof cloth production, and in particular to a cutting device for waterproof cloth for luggage. Background Art

[0002] In the existing bag making process, the waterproof cloth used on the bags is mostly cut by a cutting knife driven by an electric slide. However, the waterproof cloth is generally placed on objects of different shapes. This device can only make the electric slide drive the cutting knife to cut left and right, and cannot cut waterproof cloth of different shapes according to irregular shapes. Cutting waterproof cloth of different shapes requires constantly turning the waterproof cloth over and cutting, which is cumbersome and wastes a lot of time and cost.

[0003] Therefore, Chinese patent CN220927290U discloses a chemical fiber waterproof cloth cutter, comprising a workbench; a rotating assembly is provided on the workbench, and the rotating assembly includes a support block for rotating the cutter; a fixing assembly is provided on the workbench, and the fixing assembly includes a fixed block for fixing the chemical fiber waterproof cloth; a cutting assembly is provided on the workbench, and the cutting assembly includes a cutting knife for cutting the chemical fiber waterproof cloth; a second slide groove is provided on the supporting block, and the chemical fiber waterproof is fixed by the fixed block, and then the second rotating column slides in the second slide groove, driving the sliding frame to move left and right, and the connecting column at the bottom of the sliding frame rotates to drive the rotating disk to rotate, and the rotating disk drives the cutting knife to cut the chemical fiber waterproof cloth according to the required shape, avoiding the need to move the chemical fiber waterproof cloth all the time to cut the shape, saving a lot of manpower and time costs.

[0004] However, when the rotating disk drives the cutting knife to move for cutting, the irregularly shaped part of the waterproof cloth that has been cut loses the fixation of the fixing components at both ends and is prone to displacement. When the waterproof cloth is subsequently cut according to the pre-set cutting trajectory, cutting deviations are prone to occur, resulting in defective products and increasing the defective rate of waterproof cloth cutting.

This facilitates the connection and combination of several groups of fixed platforms to form a form with lock hole structures at both ends. Then, the fixed platforms are connected to form a ring-shaped workbench through a group of fixed platforms with lock rod structures on both sides. This design facilitates the connection of fixed components and improves the efficiency of building the workbench.
