[0019] Example 1

[0020] like Figures 1 to 3 As shown, the present invention proposes a fiber cutting tool structure, including a mounting base 1, a fiber cutting tool, a drive mechanism, and a dust collection hood; the mounting base 1 is connected to a first drive component in the cutting seat of a vibrating knife cutting machine; the fiber cutting tool is detachably mounted on the bottom end of the mounting base 1; the drive mechanism is mounted on the mounting base 1; the dust collection hood is slidably connected to the outer circumference of the mounting base 1, and the dust collection hood is driven by the drive mechanism to adjust along the height direction of the mounting base 1; the dust collection hood consists of a first cover 202, a second cover 203 mounted on the bottom end of the inner wall of the first cover 202, multiple sets of dust collection ports 204 evenly distributed on the second cover 203, and a dust collection pipe 205. The structure consists of a first cover 202 that is slidably connected to the outer periphery of the mounting base 1 and is mounted on the drive mechanism. The first cover 202 and the second cover 203 form a dust collection chamber. The input end of the dust collection pipe 205 is connected to the dust collection chamber, and the other end of the dust collection pipe 205 is mounted on the top of the first cover 202 through a limiting seat. The output end of the dust collection pipe 205 is provided with a connecting valve. The dust collection pipe 205 is connected to an external dust collection mechanism through the connecting valve. The external dust collection mechanism can use suction to suck in the dust and fibers generated by the fiber cutting knife along the suction port 204 and collect the dust and fibers in its own collection box, eliminating the need for manual cleaning of dust and fibers multiple times.

[0021] Furthermore, the drive mechanism includes a threaded rod 2 and a guide rod; the threaded rod 2 is rotatably connected to the mounting base 1; the guide rod is mounted on the mounting base 1 and on the side opposite to the threaded rod 2, and the first cover 202 is adjustablely mounted between the threaded rod 2 and the guide rod.

[0022] Furthermore, two sets of sliding grooves 101 are symmetrically provided on the mounting base 1. The threaded rod 2 and the guide rod are respectively installed in the corresponding sliding grooves 101. Two sets of sliders 201 are symmetrically installed on the first cover 202. The two sets of sliders 201 slide in the corresponding sliding grooves 101. The sliders 201 are threadedly connected to the threaded rod 2 or slidably connected to the guide rod. The first cover 202 is slidably connected to the outer circumferential surface of the mounting base 1. The outer circumferential surface of the threaded rod 2 is threadedly connected to an abutment seat, which abuts against the top of the mounting base 1. When the threaded rod 2 is adjusted to a suitable position, the abutment seat is rotated to make it abut against the top of the mounting base 1, which can limit the threaded rod 2, maintain the stability of the dust collection cover, and avoid interfering with the operation of the fiber cutting knife.

[0023] In this embodiment, in the initial state, the mounting base 1 is connected to the first drive component in the cutting seat of the vibrating knife cutting machine. This is existing technology and will not be described in detail. The fiber cutting knife is installed on the mounting base 1, and the abutment seat is rotated to move away from the top of the mounting base 1. Then, the threaded rod 2 is rotated, and under the guidance of the slide groove 101, the slider 201 slides up or down along the slide groove 101 to adjust, thereby driving multiple sets of dust suction ports 204 to correspond with the fiber cutting knife. Then, the abutment seat is rotated until it is pressed against the top of the mounting base 1, thereby limiting the threaded rod 2. The dust suction hood can be adjusted according to the size of the fiber cutting knife. Then, the external dust suction mechanism is connected to the connecting valve at the top of the dust suction pipe 205. The equipment is started to cut the fiber through the fiber cutting knife. The external dust suction mechanism accurately absorbs and collects the dust and fiber generated by the fiber cutting knife in the dust collection box in the external dust suction mechanism through multiple sets of dust suction ports 204 and dust suction pipe 205. The fiber cutting knife can work continuously without the need for temporary equipment to handle dust and fiber, thus improving processing efficiency.

[0024] Example 2

[0025] like Figures 2 to 4 As shown, the fiber cutting tool structure proposed in this utility model, compared with the first embodiment, has an installation cavity 102 inside the mounting base 1, and a slot 103 connected to the bottom end of the mounting cavity 102. A quick-release mechanism is provided in the mounting cavity 102, and the fiber cutting tool is detachably connected to the mounting base 1 through the quick-release mechanism.

[0026] Furthermore, the fiber cutting blade is composed of a mounting part 3 and a cutting part 301 mounted at its bottom end. The mounting part 3 has an insertion hole on its side wall, which corresponds to the quick release mechanism. The top end of the mounting part 3 abuts against the top end of the mounting cavity 102, and the side wall of the mounting part 3 is slidably inserted into the slot 103.

[0027] Furthermore, the quick-release mechanism includes a telescopic rod 4, a spring 402, and a lever 403. The telescopic rod 4 is installed on the side wall of the mounting cavity 102. An abutment plate 401 is installed at the other end of the telescopic rod 4, and an insertion rod 404 is installed at the other end of the abutment plate 401. The abutment plate 401 abuts against the mounting part 3, and the insertion rod 404 is inserted into the insertion hole. The spring 402 is sleeved on the outside of the telescopic rod 4 and connects the side wall of the mounting cavity 102 and the abutment plate 401. The lever 403 is installed on the abutment plate 401. A guide port 104 is opened at the bottom of the mounting cavity 102 and located on the mounting base 1. The lever 403 passes through the guide port 104 and is slidably connected to it. Two sets of the telescopic rod 4, the insertion rod 404, and the lever 403 are provided.

[0028] In this embodiment, when it is necessary to replace different models of fiber cutters, adjust the drive mechanism to move the dust cover along the mounting base 1 to the highest position, then slide the lever 403 along the guide port 104 to move it away from the slot 103, and push the abutment plate 401 towards the telescopic rod 4 through the lever 403 until the telescopic rod 4 and the spring 402 are compressed, and then the insertion rod 404 moves away from the insertion hole on the mounting part 3. At this time, a protective tool can be used to wrap around the outside of the cutting part 301 and slide it out along the slot 103 to complete the disassembly of the fiber cutter. Then, other models of fiber cutters can be installed in the same way.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
