Abstract
Description
Technical Field
[0001] This utility model relates to the field of nylon filament cutting technology, specifically to a nylon filament cutting mechanism. Background Technology
[0002] After nylon filaments are produced, they are usually wound into bundles for storage and transportation. Subsequent applications (such as making brushes, woven products, etc.) require the nylon to be cut into filaments of specific lengths. Before this, the long bundles of nylon filaments need to be cut into short filaments of specific lengths, and then the broken filaments are used for processing. For example, when processing brushes, the nylon filaments are first bundled into long bundles, and then the long bundles are pushed to the cutting blade using a wire feeding device or manually, and then the cutting blade cuts the long nylon filaments to the required length. Currently, in the cutting of some nylon bundles, a baffle is usually set on the feeding side of the cutting blade to limit the nylon bundle. However, most of these baffles are fixedly installed. This design flaw not only obstructs the feeding process of the bundle, but also makes it inconvenient to adjust the cutting length.
[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0030] like Figures 1 to 4 As shown, this utility model discloses a nylon filament cutting mechanism, comprising: a table 1, which is rectangular in shape; and a filament cutting mechanism disposed on the top of the table 1.
[0031] A limiting component 2 for limiting the nylon wire harness; a cutting component 26 for cutting the nylon wire harness; and a second telescopic cylinder 18 installed on the top of the platform 1.
[0032] A connecting block 27 is drivenly connected to the piston rod of the second telescopic cylinder 18. The connecting block 27 has an L-shaped cross-section and a connecting through hole on its vertical part. The connecting through hole is fixedly connected to the piston rod of the second telescopic cylinder 18. A second slider 20 is fixedly connected to the connecting block 27. The horizontal part of the connecting block 27 is fixedly connected to the top of the second slider 20. A guide rail 19 is slidably connected to the second slider 20. The guide rail 19 is fixedly installed on the top of the table 1. The guide rail 19 includes: an L-shaped mounting plate symmetrically installed on the top of the table 1 along the length direction of the table 1, and two cylindrical rods installed between the two opposite L-shaped mounting plates. The two cylindrical rods are slidably connected to the second slider 20 respectively and are used to guide the second slider 20. A pressing block 21 is installed on the second slider 20. The cutting component 26 is located on the extension stroke of the pressing block 21 and is used to press against the nylon wire harness for easy cutting. The cutting length of the nylon wire harness can be adjusted by adjusting the stroke of the pressing block 21. In this embodiment, by setting a second telescopic cylinder 18 on the feeding side and driving the pressing block 21 to slide through the second telescopic cylinder 18, it is convenient to limit the nylon wire harness and slide in the opposite direction after cutting to avoid interfering with the feeding of the nylon wire harness.
[0033] Preferably, the cutting assembly 26 includes: a gantry 8 fixedly installed on the top of the table 1 and located between the limiting assembly 2 and the pressing block 21; a first telescopic cylinder 9 fixedly installed on the top of the gantry 8; and a cutter 10 drivenly connected to the piston rod of the first telescopic cylinder 9. The first telescopic cylinder 9 is used to drive the cutter 10 to move up and down to complete the cutting action and cut the nylon wire harness.
[0034] Preferably, the piston rod of the second telescopic cylinder 18 is also connected to a first rack 17, which is arranged along the length of the platform 1; the first rack 17 is meshed with a first gear 16, which is rotatably mounted above the platform 1; a cylindrical mounting block 3 is mounted on the top of the platform 1, and a drive shaft is rotatably mounted on the cylindrical mounting block 3, which is coaxially connected to the first gear 16; when the first rack 17 moves, it drives the first gear 16 to rotate; the first gear 16 is coaxially connected to a second gear 15, which is coaxially connected to the drive shaft; the second gear 15 is driven by a second rack 14, which is arranged along the width of the platform 1; the second rack 14 is slidably connected to a limit rod 25, which is fixedly mounted on the gantry 8 for limiting the second rack 14.
[0035] A feeding groove 12 is provided between the pressing block 21 and the cutter 10 to catch the cut nylon filaments for easy feeding; one end of the second rack 14 is connected to a push block 13, which is located on the feeding side of the cutting assembly 26 and is slidably connected to the feeding groove 12; when the second gear 15 rotates, it drives the second rack 14 to move horizontally, thereby driving the push block 13 to push the cut nylon filaments to the feeding side.
[0036] Preferably, the limiting component 2 includes: a mounting block 3 symmetrically installed on the top of the tabletop 1 along the width direction, and two circular holes are sequentially opened on the mounting block 3 from top to bottom; wherein, the mounting blocks 3 are arranged in two groups opposite each other, and each group is symmetrically arranged with two blocks along the width direction of the tabletop 1.
[0037] In this setup, a limiting post 6 is installed in the round hole of a set of mounting blocks 3 located on the feeding side; a first threaded rod 5 and a limiting post 6 are installed in the round hole of a set of mounting blocks 3 located on the unloading side; the first threaded rod 5 is located above the limiting post 6, and when different limiting layouts are required, the first threaded rod 5 can also be located below the limiting post 6.
[0038] The first threaded rod 5 is threadedly connected to the first slider 4; the first slider 4 has two round holes, one of which is threadedly connected to the first threaded rod 5, and the other round hole is slidably connected to the limiting post 6, so as to ensure that the slider maintains stable guidance during the adjustment process.
[0039] The first slider 4 is symmetrically arranged in two rows along the width direction of the platform 1. Guide blocks 11 are respectively installed on the top of the two rows of first sliders 4. The side of the two guide blocks 11 that is close to each other is arc-shaped, which is used to guide and limit the nylon wire harness, so that the nylon wire harness can slide between the two guide blocks 11. One end of the first threaded rod 5 is fixedly connected to a first handwheel 7. By rotating the first handwheel 7, the distance between the two first sliders 4 can be adjusted, thereby adjusting the distance between the two guide blocks 11, so that the guide blocks 11 can adapt to nylon wire harnesses of different diameters.
[0040] Preferably, a second threaded rod 23 is fixedly connected to one end of the pressing block 21 away from the cutting assembly 26. The second threaded rod 23 is threadedly connected to a mounting base 22, and the other end of the second threaded rod 23 (the end away from the pressing block 21) protrudes from the mounting base 22. A second handwheel 24 is fixedly connected to the protruding end of the second threaded rod 23. By rotating the second handwheel 24, the distance between the pressing block 21 and the cutter 10 can be adjusted, thereby adjusting the cutting length. In this way, the second telescopic cylinder 18 only needs to move back and forth for a fixed length to achieve the cutting of nylon wire harnesses of different lengths, thus not affecting the stroke of the push block 13. The mounting base 22 is fixedly installed on the top of the second slider 20.
[0041] The second telescopic cylinder 18 extends and retracts, causing the connecting block 27 to slide, which in turn causes the second slider 20 to slide along the guide rail 19, thereby causing the pressing block 21 to slide.
[0042] Working principle: Before the cutting operation, the operator first neatly bundles the nylon filaments into a long wire harness, and then places it on the feeding side of the wire cutting mechanism. Next, the operator places the nylon wire harness between two guide blocks 11. The operator rotates the first handwheel 7 according to the diameter of the wire harness to adjust the spacing of the guide blocks 11, so that the guide blocks 11 fit tightly against the wire harness, achieving precise positioning.
[0043] After the limit is completed, the operator activates the second telescopic cylinder 18. The piston rod extends and drives the second slider 20 and its connected pressing block 21, second threaded rod 23, mounting base 22, and second handwheel 24 to slide towards the guide block 11 until they reach the predetermined position and stop. At the same time, the second telescopic cylinder 18 drives the first rack 17 to slide. Through the transmission of the second gear 15 and the first gear 16, the second rack 14 is driven to move outward from the table surface 1, thereby pushing the push block 13 away from the cutting area and making room for subsequent cutting.
[0044] When the nylon harness is pushed to contact the pressure block 21, the operator activates the first telescopic cylinder 9, driving the cutter 10 to fall and cut the nylon harness.
[0045] After the cutting is completed, the operator starts the second telescopic cylinder 18 again, causing its piston rod to retract and drive the pressure block 21 to move in the opposite direction, separating it from the cut nylon wire harness; at the same time, the push block 13 slides towards the cutter 10, pushing the cut nylon wire harness away from the working area, and the feeding process is completed by reciprocating push.
[0046] In addition, if it is necessary to adjust the cutting length of the nylon filament, the operator can turn the second handwheel 24 to easily adjust the distance between the pressure block 21 and the cutter 10, and quickly complete the precise adjustment of the cutting length.
