Description

Technical Field

[0001] This application relates to the field of nylon filament processing, and more specifically, to a cutting device for nylon filament processing. Background Technology

[0002] Nylon filament processing refers to a series of treatments and manufacturing processes performed on nylon (polyamide fiber) filaments. This includes spinning nylon raw materials into continuous filament fibers, followed by subsequent processing steps such as stretching and heat setting to improve the physical and mechanical properties of the fibers, giving them specific characteristics such as strength, elasticity, and luster.

[0003] Patent document CN222273747U discloses a cutting device for nylon filament processing. This utility model relates to the field of nylon filament processing technology, specifically a cutting device for nylon filament processing, including a supporting base plate. The supporting base plate is provided with a filament pressing mechanism, which includes a supporting frame. The supporting frame is fixedly installed on the top of the supporting base plate, and a groove is provided on the supporting frame. In the above application, the nylon filament is pressed and fixed by a filament pressing block for cutting. However, when it is necessary to cut nylon filament textile fabric, after the filament pressing block presses down on the nylon filament fabric, the nylon filament fabric is compressed in a relatively loose state, which makes it difficult for the cutter to cut flat. It is not convenient to tension the nylon filament fabric to make flat cutting. Utility Model Content

Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0016] See Figures 1-4This embodiment provides a cutting device for nylon yarn processing, including a base plate 1, a cutting assembly 2 disposed above the base plate 1, the cutting assembly 2 including a cutting seat 201, the cutting seat 201 having a deep cutting groove, a support frame 202 fixedly connected to the outer surface of the cutting seat 201, the support frame 202 being U-shaped, a cutter 203 slidably connected to the inner surface of the support frame 202, the cutter 203 having an inclined blade, the cutting assembly 2 also including an electric push rod 204, the electric push rod 204 being fixedly connected to the upper surface of the support frame 202, the electric push rod 204... The output end is slidably connected to the upper part of the support frame 202. The output end of the electric push rod 204 is fixedly connected to the upper surface of the cutter 203. Two limit rods 205 are fixedly connected to the upper surface of the cutter 203. The limit rods 205 are slidably connected to the upper surface of the support frame 202. Pressing components 3 are provided on the left and right sides of the cutter 203. The pressing components 3 include connecting pieces 301, which are fixedly connected to the outer surface of the cutter 203. An elastic telescopic rod 302 is fixedly connected to the lower surface of the connecting piece 301. Specifically, it includes a sleeve rod and a movable rod, with a spring between the sleeve rod and the movable rod. The elastic telescopic rod 302 can elastically return to its original position after compression, which is existing technology. A lifting seat 303 is fixedly connected to the lower end of the elastic telescopic rod 302. Pressure rods 304 are fixedly connected to both sides of the lifting seat 303. The pressing assembly 3 also includes a limiting block 305, which is fixedly connected to the outer surface of the support frame 202. A guide assembly 4 is provided on the left side of the cutting assembly 2. The guide assembly 4 includes a first rotating shaft 401, and a guide roller 40 is fixedly connected to the outer surface of the first rotating shaft 401. 2. There are two first rotating shafts 401 and guide rollers 402. The outer surface of the first rotating shaft 401 is rotatably connected to a first support plate 403. The first support plate 403 is fixedly connected to the top of the base plate 1. A winding assembly 5 is provided on the right side of the cutting assembly 2. The winding assembly 5 includes a second rotating shaft 501. A winding drum 502 is fixedly connected to the outer surface of the second rotating shaft 501. The outer surface of the second rotating shaft 501 is rotatably connected to a second support plate 503. The second support plate 503 is fixedly connected to the top of the base plate 1. A flattening assembly 6 is provided on the outer surface of the cutter 203.

[0017] In practical use, the nylon fabric is first passed through the guide roller 402 and above the cutting seat 201, connecting the nylon fabric to the take-up drum 502. The nylon fabric is wound up by the rotation of the take-up drum 502. When it is necessary to cut the wound nylon fabric, the electric push rod 204 is activated to extend it. The electric push rod 204 will push the cutter 203 to descend. The descent of the cutter 203 will first drive the connecting piece 301 to descend. The connecting piece 301 will drive the elastic telescopic rod 302 to descend the lifting seat 303 until the lifting seat 303 descends to contact the limit block 305. At this time, the continued descent of the cutter 203 will compress the elastic telescopic rod 302. When the lifting seat 303 descends to contact the limit block 305, it will drive the pressure rod 304 to descend, thereby pressing the nylon fabric from above. The nylon fabric will be tensioned above the cutting seat 201 so that the cutter 203 can descend to cut the nylon fabric flat. Example

[0018] See Figures 1-4 Based on Embodiment 1, the leveling component 6 includes a guide groove 601, which is inclined with the same inclination as the blade of the cutter 203. The guide groove 601 is located on the right side of the cutter 203 and is through-hole. A connecting rod 602 is slidably connected to the inner surface of the guide groove 601. The connecting rod 602 is U-shaped. A sliding sleeve 603 is fixedly connected to the lower end of the connecting rod 602. The sliding sleeve 603 is square-shaped. A sliding strip 604 is slidably connected to the inner surface of the sliding sleeve 603. The sliding strip 604 is fixedly connected to the inner surface of the support frame 202. A bracket 605 is fixedly connected to the lower surface of the sliding sleeve 603. The bracket 605 is Z-shaped. A roller 606 is rotatably connected to the inner surface of the bracket 605.

[0019] In practical use, when the cutter 203 descends to cut the nylon fabric, the rear end of the cutter 203 will first contact the nylon fabric. At this time, as the cutter 203 descends, it will drive the guide groove 601 to descend. As the guide groove 601 descends, it will push the connecting rod 602 to slide forward within the guide groove 601. The connecting rod 602 will drive the sliding sleeve 603 to slide forward on the sliding strip 604. The sliding sleeve 603 will drive the bracket 605 to move the roller 606 forward. At this time, the roller 606 will roll forward on the nylon fabric, thereby smoothing out the wrinkles on the nylon fabric to further ensure a flat cut.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
