Description

Technical Field

[0001] The utility model belongs to the technical field of monofilament cutting, and in particular relates to a monofilament cutting device which is easy to adjust. Background Art

[0002] Monofilament refers to a single filament with a smaller count produced by a single-hole spinneret in chemical fiber production. It is characterized by thinness, transparency and good hand feel.

[0003] When cutting monofilaments, different types of monofilament reels have different sizes. Some existing cutting devices are not convenient for fixing the reels on monofilament reels of different sizes, and some cutting devices are not convenient for accurately cutting the monofilament according to the required length. In view of this, we propose a monofilament cutting device that is easy to adjust. Utility Model Content

[0004] The purpose of the utility model is to provide a monofilament cutting device which is easy to adjust, so as to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a monofilament cutting device that is easy to adjust, comprising:

[0006] A workbench, wherein a support plate is fixedly installed on the workbench, a turntable is rotatably installed in the support plate, a slide groove is provided on the turntable, two sliding blocks 1 are slidably installed in the slide groove, a semicircular plate is fixedly installed on one side of the two sliding blocks 1, and an anti-slip pad is fixedly installed on the side of the two semicircular plates away from each other;

[0007] A driving assembly, the driving assembly is located in the turntable and is used to drive the two sliding blocks to move closer to each other or away from each other;

[0008] A U-shaped plate, the U-shaped plate is fixedly mounted on the top of the workbench and is located directly in front of the anti-slip pad, a sliding block 2 is slidably mounted in the U-shaped plate, and a threaded rod is rotatably mounted on the top of the sliding block 2, and the upper end of the threaded rod passes through the top of the U-shaped plate and extends to the outside;

[0009] Two cylinders, the two cylinders are fixedly installed on the top of the workbench and located in front of the U-shaped plate, the same extrusion plate is slidably installed on the two cylinders, springs are sleeved on the outside of the two cylinders and located at the bottom of the extrusion plate, a cutting blade is fixedly installed at the bottom of the extrusion plate and located between the two springs, and a scale line is fixedly installed on the top of the workbench and located in front of the extrusion plate.

[0010] In the present technical scheme, when in use, the monofilament wire together with the winding tube is first put on the anti-skid pads on the two semicircular plates, and the monofilament wire reel is located directly behind the U-shaped plate. Subsequently, the driving assembly is rotated to make the driving assembly drive the two sliding blocks to move away from each other, and the two sliding blocks will drive the two semicircular plates to move away from each other until the two anti-skid pads on the two semicircular plates are against the inner wall of the winding tube. Under the action of the anti-skid pads, the friction force with the inner wall of the winding tube can be increased to make it more stably fixed. Subsequently, the thread end on the monofilament wire reel is found and the thread end is pulled. While pulling, the monofilament wire reel is fixed on the two semicircular plates, so that the monofilament wire reel will drive the two semicircular plates to rotate together, and the rotation of the two semicircular plates will drive the two sliding blocks to rotate together. The rotation of the two sliding blocks will drive the bidirectional threaded rod to rotate together, and the double The threaded rod drives the turntable to rotate, and then the thread end passes through the U-shaped plate and between the two cylinders. Then, according to the required length and the scale line, the thread end can be moved to the position of the required length. Then, the threaded rod is rotated. Under the action of the thread, the threaded rod will rotate and move downward. At the same time, the threaded rod will drive the sliding block 2 to move downward until the sliding block 2 fixes the monofilament in the U-shaped plate. At this time, the thread end is still held in the hand of the staff and is in a taut state. Then, the extrusion plate is pressed again to make the extrusion plate drive the cutting blade to move downward until the cutting blade cuts off the monofilament. At the same time, the two springs will shrink due to the extrusion. After the cutting is completed, under the action of the rebound of the two springs, the two springs will push the extrusion plate to move upward, so that it drives the cutting blade to return to its original position.

[0011] In the above technical solution, further, the driving component includes:

[0014] In the present technical solution, the handle is rotated to drive the worm to rotate. Under the action of meshing, the worm will drive the worm wheel to rotate, and the rotation of the worm wheel will drive the bidirectional threaded rod to rotate. Under the action of the thread, the bidirectional threaded rod will drive the two sliding blocks to move away from each other, and the two sliding blocks will drive the two semicircular plates to move away from each other until the two anti-slip pads on the two semicircular plates are against the inner wall of the winding tube. Under the action of the anti-slip pads, the friction with the inner wall of the winding tube can be increased, making it more stably fixed.

[0015] In the above technical solution, further, the bidirectional threaded rod is provided with two sections of threads with opposite rotation directions, the two sliding blocks are both threadedly connected to the bidirectional threaded rod, and the bidirectional threaded rod is rotationally connected to the power chamber.

[0016] In the technical solution, under the action of the thread, it is ensured that the bidirectional threaded rod can drive the two sliding blocks to move closer to or away from each other when rotating.

[0017] In the above technical solution, further, the threaded rod is threadedly connected to the U-shaped plate.

[0018] In this technical solution, under the action of the thread, it is ensured that the threaded rod can drive the sliding block 2 to move downward.
