Description

Technical Field

[0001] This utility model relates to the field of cotton yarn sliver technology, specifically a cotton yarn sliver cutting device. Background Technology

[0002] Cotton yarn is yarn made from cotton fibers through spinning processes. After being processed into ply, it is called cotton thread. Depending on the different spinning processes, it can be divided into carded yarn and combed yarn. Cotton yarn strips are generally wound on a spool. When needed, the cotton yarn strip is pulled out directly and then cut to the specified length by hand or machine.

[0003] According to Chinese Utility Model Patent Application No. 202420440268.6, a cotton yarn sliver cutting device for cotton yarn processing is proposed. The utility model describes that "the cotton yarn sliver to be cut can be placed on the surface of the base plate, and the pressure rollers can be lifted upwards by hand so that the two pressure rollers can press the left and right sides of the cotton yarn sliver tightly. At this time, the cotton yarn sliver can be pulled left and right by hand. This not only ensures that the part of the cotton yarn sliver between the two pressure rollers is tightened, but also adjusts the position of the cotton yarn sliver directly below the cutting mechanism to adjust the cutting position. Then, the cotton yarn sliver can be cut by lowering the cutting mechanism. This cutting method not only avoids the cotton yarn sliver from sliding and shifting during cutting, but also accurately cuts the cotton yarn sliver to the required length for the process."

[0004] The cotton yarn sliver cutting device for cotton yarn processing involves the operator holding a handle to move a sliding rod, a concave mounting bracket, and a pressure roller upwards, compressing a spring. The cotton yarn sliver then passes through the pressure roller. Releasing the handle allows the spring to return to its original shape, causing the pressure roller to move downwards and thus limiting the cotton yarn sliver. This method is not only cumbersome to operate, but the cotton yarn sliver may also be loose, affecting the cutting effect. Therefore, an improvement is needed. This paper proposes a cotton yarn sliver cutting device to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 The cotton yarn strip cutting device in this embodiment includes a workbench 1, a cover 2 fixedly installed on the top of the workbench 1, a cutting mechanism 3 and a moving mechanism 4 provided on the cover 2, and a limiting mechanism 5 provided on the moving mechanism 4.

[0023] Specifically, the staff first passes the cotton yarn through the limiting mechanism 5 and the cutting mechanism 3. Then, the limiting mechanism 5 is used to limit the cotton yarn, and the moving mechanism 4 is used to move the limiting mechanism 5 to stretch the cotton yarn. The cotton yarn is then manually moved to the designated position, and finally the cutting mechanism 3 is used to cut the cotton yarn. This method is not only simple to operate, but also ensures that the cotton yarn remains taut, thus improving the cutting effect.

[0024] In this embodiment, the cutting mechanism 3 includes a hydraulic cylinder 31, which is fixedly connected to the inner top wall of the cover 2. A horizontal plate 32 is fixedly installed at the output end of the hydraulic cylinder 31. A slider extending into the inside of the cover 2 is fixedly installed on the outside of the horizontal plate 32. A groove matching the slider is opened on the inner side wall of the cover 2. A cutting blade 33 is detachably installed at the bottom of the horizontal plate 32. A mounting plate is fixedly installed on the top of the cutting blade 33. The mounting plate is connected to the bottom of the horizontal plate 32 by bolts. There are four bolts, which are distributed at the four corners. A through hole matching the cutting blade 33 is opened on the top of the worktable 1.

[0025] Specifically, by activating the hydraulic cylinder 31, the hydraulic cylinder 31 drives the horizontal plate 32 and the cutting blade 33 to move downwards, and the cutting blade 33, in conjunction with the through hole, cuts the cotton yarn strip.

[0026] In this embodiment, the moving mechanism 4 includes a chamber 41, which is fixedly connected to the top of the cover 2. A dual-axis motor 42 is fixedly installed on the top of the cover 2. Threaded rods 43 are fixedly installed on both output ends of the dual-axis motor 42. The opposite sides of the two threaded rods 43 are rotatably connected to the inner wall of the chamber 41 via a first bearing. The threads of the two threaded rods 43 are opposite in direction and of the same length. Threaded sleeves 44 are threadedly installed on the outside of each of the two threaded rods 43. Moving rods 45, which penetrate and extend below the chamber 41, are fixedly installed at the bottom of each of the two threaded sleeves 44. The two moving rods 45 are located on both sides of the hydraulic cylinder 31. Two moving holes are opened on the top of the worktable 1, and the two moving holes are matched with the two moving rods 45 respectively. Moving plates 46 are fixedly installed at the bottom of each of the two moving rods 45.

[0027] Specifically, by activating the dual-axis motor 42, the dual-axis motor 42 drives the two threaded rods 43 to rotate, and the two threaded rods 43 drive the two threaded sleeves 44, the two moving rods 45 and the two moving plates 46 to move relative to each other or in opposite directions.

[0028] In this embodiment, the limiting mechanism 5 includes two electric push rods 51, which are fixedly connected to the bottom of two moving plates 46 respectively. The output ends of the two electric push rods 51 are fixedly installed with U-shaped frames 52, and the inner sidewalls of the two U-shaped frames 52 are rotatably installed with rollers 53 through the second bearing.

[0029] Specifically, by activating two electric push rods 51, the two electric push rods 51 drive two U-shaped frames 52 and two circular rollers 53 to move downwards, and the two circular rollers 53 limit the cotton yarn strip.

[0030] In this embodiment, a collection mechanism 6 is provided at the bottom of the workbench 1. The collection mechanism 6 includes a frame 61, which is fixedly connected to the bottom of the workbench 1. A collection box 62 is placed on the top of the frame 61.

[0031] Specifically, the debris generated from cutting falls through the through-hole into the inside of the collection box 62.

[0032] The working principle of the above embodiments is as follows:

[0033] The operator first passes the cotton yarn through two circular rollers 53 and a cutting blade 33. Then, the operator activates two electric push rods 51, which drive two U-shaped frames 52 and two circular rollers 53 to move downwards. The two circular rollers 53 limit the movement of the cotton yarn. The operator then activates a dual-axis motor 42, which drives two threaded rods 43 to rotate. The two threaded rods 43 drive two threaded sleeves 44, two moving rods 45, two moving plates 46, two electric push rods 51, two U-shaped frames 52, and two circular rollers 53 to move in opposite directions, stretching the cotton yarn. The operator then manually moves the cotton yarn to a designated position, where it drives the two circular rollers 53 to rotate. Finally, the operator activates a hydraulic cylinder 31, which drives a horizontal plate 32 and a cutting blade 33 to move downwards. The cutting blade 33, in conjunction with a through hole, cuts the cotton yarn. The resulting debris falls through the through hole into a collection box 62. This method is not only simple to operate but also ensures that the cotton yarn remains taut, improving the cutting effect.
