Description

Technical Field

[0001] This utility model relates to the technical field of fabric spreading machine equipment, and in particular to a fabric spreading machine edge cutting mechanism. Background Technology

[0002] Fabric spreading machines are essential pieces of machinery in the textile industry, used to lay fabric flat on a worktable for cutting or printing. With the development of automation and intelligent technologies, modern fabric spreading machines have achieved high-speed and precise fabric feeding, greatly improving production efficiency and quality. However, existing fabric spreading machines use a bolted-on cutter assembly that is entirely bolted to the machine body. When the cutter assembly needs maintenance or replacement, the entire assembly must be disassembled, resulting in low disassembly and maintenance efficiency, lacking a quick-release function, and being inflexible and inconvenient. Utility Model Content

[0003] (1) Technical solution

[0004] To solve the above-mentioned technical problems, this utility model provides a cutting edge mechanism for a fabric spreading machine. The cutting edge mechanism is installed on the main body of the fabric spreading machine. The cutting edge mechanism includes a bracket at the front end of the main body of the fabric spreading machine. The bracket includes a left support plate and a right support plate installed on the main body of the fabric spreading machine. A ball screw is provided between the left and right support plates. Guide rods are provided on both the front and rear sides of the ball screw. A movable block is sleeved on the ball screw. The movable block is composed of two small movable blocks. Both small movable blocks have inward threads that match the ball screw. When the ball screw rotates, the two small movable blocks move in coordination. A snap-fit ​​plate is provided on the outward side of each of the two small movable blocks. The snap-fit ​​plate is assembled on the guide rod. A collar is provided at both the left and right ends of the movable block. During assembly, the screw passes sequentially through the snap-fit ​​plate at the front end, enters the two small movable blocks, and is finally installed on the snap-fit ​​plate at the rear end. The front and rear ends of the screw are locked with nuts.

[0005] Each movable block has a limiting channel at its bottom to facilitate the insertion of the pressing component. After the pressing component is inserted into the limiting channel, it is locked by a second bolt. The pressing component includes pressure plates at both ends. A cutting component is provided between the two pressure plates. The cutting component includes a lifting end and a cutting tip. The lifting end is a two-end type. After assembly, the two ends of the lifting end are respectively installed on the two movable blocks.

[0006] Preferably, the left and right ends of the ball screw are installed inside the receiving seat, and one side of the ball screw extends outward and is connected to the output shaft of the drive motor.

[0007] Preferably, the screw is disposed on the outside of the sleeve ring.

[0008] Preferably, the pressure plate includes an upright portion, with an arc-shaped upward-curving portion below the upright portion, and a hook end with an inverted L-shaped buckle at the top of the upright portion.

[0009] Preferably, the middle part of the lifting end is provided with a U-shaped recessed groove, and the two ends of the lifting end are locked to the corresponding movable blocks by first bolts, and the ends of the first bolts are tightened by nuts.

[0010] Preferably, each of the movable blocks has a mating groove in the middle that mates with the lifting end.

[0011] Preferably, the sleeve ring is also provided with threads that mate with the ball screw, and the pressing element is an elastic metal sheet.

[0012] (2) Beneficial effects

[0013] This utility model provides a cutting edge mechanism for a fabric spreading machine. Compared with the prior art, this utility model has the following advantages: This utility model sets a bracket at the front end of the fabric spreading machine body, and sets a ball screw and a guide rod on the bracket. A drive motor drives the ball screw to rotate, which in turn moves the movable block on the ball screw. To facilitate quick disassembly, the movable block connected to the ball screw is formed by splicing and locking two small movable blocks. The two small movable blocks have internal threads that match the ball screw, and one end has a connecting ring for easy engagement with the guide rod. A pressing component is provided below each small movable block, and a cutting component is connected to the middle of both small movable blocks, thus achieving the effect of pressing and cutting simultaneously. The pressing component achieves quick assembly through a limiting channel at the bottom of the small movable block. The cutting component achieves a block-like effect through a second bolt. The two small movable blocks achieve quick assembly through a screw set from the front end to the rear end and a nut tightened on the outside of the screw, making the cutting edge mechanism easier to maintain and replace.
