Technical Field

[0001] The utility model relates to the technical field of fixed-width cutting devices, in particular to a fixed-width cutting device for PVC plastic floors. Background Art

[0002] PVC plastic flooring is usually produced on wide rolls of raw materials, but the final product may require floors of different widths. The use of a fixed-width cutting device can improve production efficiency and ensure that PVC plastic flooring that meets specifications can be produced in a shorter time. The market demand for PVC plastic flooring may include different width specifications to suit different application scenarios. By using a device with a fixed-width cutting function, manufacturers can more flexibly meet customers' customized needs.

[0003] After searching, the existing patent (Announcement No.: CN207698881U) discloses a material fixed width cutting device, including: a feeding device, including an unwinding shaft for unwinding the carbon fiber material to be cut, a guide roller, and a traction device for providing forward power to the carbon fiber material, wherein the guide roller is arranged in the running direction of the carbon fiber material, and is used to provide support force to the carbon fiber material; an edge finding device, used to measure the edge of the carbon fiber material along the width direction; a control center, which is respectively connected to the cutting device and the edge finding device, and is used to control the cutting operation of the cutting device. The edge finding device can detect the edge of the carbon fiber material, and the control device controls the movement of the cutting device to set the initial cutting position, and then starts cutting at the initial cutting position, so that the cutting is more accurate, and the use of automated cutting avoids the defects of low efficiency and large errors in traditional manual cutting.

[0004] However, in the above scheme, the blade is an essential consumable of the equipment and thus needs to be replaced or sharpened frequently, which results in the need to frequently disassemble the blade. If replacing the blade takes a lot of time, it will increase the downtime of the production line and reduce production efficiency.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, the spring uses the limit frame as a stress point to push the locking rod downward to lock the locking block to fix the top of the locking block, and at the same time, the spring uses the locking rod as a stress point to push the limit frame upward, and the limit frame and the bottom of the locking block are locked with each other to fix the locking block. By moving the limit frame downward and pushing the locking rod upward, the locking of the locking block can be quickly canceled, so that the blade can be quickly disassembled, which makes maintenance and replacement of the blade more convenient, which helps to reduce production downtime and improve production efficiency.

[0017] 2.
