DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 A nonwoven fabric slitting machine shown in the figure comprises a support frame 101, a slitting mechanism is arranged inside the support frame 101, a positioning mechanism is arranged between the slitting mechanism and the support frame 101, the positioning mechanism comprises a fixed beam 201 and a first rack 204, the fixed beam 201 is fixedly connected to the inner wall of the support frame 101, the slitting mechanism is slidably arranged below the fixed beam 201, a measuring mechanism is arranged on the front of the fixed beam 201, a slide groove 202 is opened on the front of the fixed beam 201, a slider 203 is slidably arranged on the inner wall of the slide groove 202, the first rack 204 is arranged at the top of the slider 203, and the slide groove 202 is provided. 02 is provided with a second rack 205 at the top end of the inner wall, the outer wall of the first rack 204 is meshed with the outer wall of the second rack 205, and the slider 203 and the slitting mechanism are provided with an extrusion mechanism. When the slitting mechanism is slid and adjusted under the fixed beam 201, the slider 203 is moved up to make the first rack 204 mesh with the second rack 205, and the slider 203 can be positioned in the slide groove 202. At this time, the slitting mechanism can be positioned under the connection of the extrusion mechanism, so that the slitting mechanism will not automatically adjust during operation, thereby improving the stability of the slitting mechanism.

[0022] Among them, the slitting mechanism includes a knife seat 301 and a slitting knife 303. A mounting groove 302 is opened at the bottom end of the knife seat 301. The slitting knife 303 is inserted into the inner wall of the mounting groove 302. A threaded hole 304 is opened on one side of the knife seat 301. The inner wall of the threaded hole 304 is threadedly connected with a locking bolt 305. The locking bolt 305 is tightened in the threaded hole 304 to position the slitting knife 303 in the mounting groove 302, so that the mounting groove 302 can stably perform slitting work at the bottom end of the knife seat 301.

[0023] Preferably, the extrusion mechanism includes a connecting plate 403 and a spring 404. The bottom end of the inner wall of the slide groove 202 is provided with a first connecting groove 401. The inner wall of the first connecting groove 401 is slidably connected with a first connecting block 402. The bottom end of the first connecting block 402 is fixedly connected to the top of the knife seat 301. The top of the first connecting block 402 is fixedly connected to the bottom end of the connecting plate 403. The spring 404 is arranged between the connecting plate 403 and the slider 203. The top of the slider 203 is provided with an unlocking mechanism. The spring 404 is positioned by the connecting plate 403, so that the spring 404 always exerts an upward force on the slider 203. , so that the first rack 204 can be stably engaged with the second rack 205, and the shape of the first connecting block 402 can be trapezoidal, and the shape of the first connecting groove 401 matches the first connecting block 402. At the same time, the setting that the connecting plate 403 cannot pass through the first connecting groove 401 can make the first connecting block 402 unable to move up in the first connecting groove 401, ensuring that the slitting mechanism can work stably, or a limit block is fixed on the outer wall of the first connecting block 402, and the limit block slides and limits in the limit groove opened on the inner wall of the first connecting groove 401, which also prevents the slitting mechanism from moving up and down.

[0024] Furthermore, the unlocking mechanism includes a second connecting block 502, a second connecting groove 501 is provided at the top of the inner wall of the slide groove 202, the outer wall of the second connecting block 502 is slidably connected to the inner wall of the second connecting groove 501, the second connecting block 502 is fixedly inserted and connected to the top of the slider 203, the top of the second connecting block 502 is fixedly connected to a pressing plate 503, and a limiting mechanism is arranged between the second connecting block 502 and the connecting plate 403. By pressing the pressing plate 503 downward, the slider 203 can be moved downward under the connection of the second connecting block 502, so that the first rack 204 is separated from the second rack 205, and the slitting mechanism can be moved and adjusted at this time.

[0025] Furthermore, the limiting mechanism includes a limiting hole 601 and a limiting rod 602. The limiting hole 601 is opened at the bottom end of the second connecting block 502. The bottom end of the limiting rod 602 is fixedly connected to the top of the connecting plate 403. The outer wall of the limiting rod 602 is movably connected to the inner wall of the limiting hole 601. The spring 404 is sleeved on the outer wall of the limiting rod 602 and is inserted into the limiting hole 601 through the limiting rod 602, so that the slider 203 can be stably connected to the slitting mechanism, thereby ensuring the stability of the operation between the positioning mechanism and the slitting mechanism.

[0026] Preferably, the measuring mechanism includes an indicator block 701 and a scale line 702. The indicator block 701 is fixedly connected to the top of the front side of the slider 203, and the scale line 702 is opened on the front side of the fixed beam 201. During the movement of the slitting mechanism, the indicator block 701 will be driven to move, so that the adjustment of the slitting mechanism can be accurately controlled by the scale change of the scale line 702 pointed to by the indicator block 701, thereby ensuring the accuracy of the operation of the slitting mechanism.

[0027] Furthermore, a plurality of fixed plates 801 are fixedly connected to the bottom end of the connecting plate 403, and a roller 802 is rotatably connected between two adjacent fixed plates 801. The outer wall of the roller 802 is fitted with the bottom end of the inner wall of the slide groove 202. When the slitting mechanism is adjusted, the connecting plate 403 will move in the slide groove 202, so that the roller 802 can roll against the inner wall of the slide groove 202, thereby reducing the friction force of the slitting mechanism during sliding adjustment, making the adjustment of the slitting mechanism smoother.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
