[0002] Polyester staple fiber is an important textile raw material, widely used in clothing, home textiles, industrial textiles and other fields. In the production process of polyester staple fiber, the cutting process is to cut the continuous polyester filament bundles to a specified length, and the cutting quality directly affects the performance of subsequent products.
[0003] Currently, existing polyester staple fiber cutting devices have the following shortcomings: low cutting accuracy, which easily causes problems such as entanglement or wrinkles when cutting polyester fiber fabric; and the inability to adjust the tension of the polyester fiber fabric, which affects the cutting accuracy and reduces the cutting efficiency. In order to solve the above problems, a polyester staple fiber cutting device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a polyester staple fiber cutting device to solve the problems mentioned in the background art.
[0005] To solve the above problems, the following technical solution is provided: a polyester staple fiber cutting device, including a cutting machine table, an unwinding frame fixedly installed on the upper end of the cutting machine table, an unwinding motor fixedly installed on the outer wall of one end of the unwinding frame, a limit frame fixedly installed on one side of the unwinding frame, a cutting protective cover fixedly installed on the upper end of the cutting machine table, a cutting structure provided inside the cutting protective cover, an adjustment structure fixedly installed on the outer wall of the cutting protective cover, a collection box provided on one side of the upper end of the cutting machine table, the adjustment structure including a mounting frame fixedly installed on the outer wall of the cutting protective cover, an adjustment motor fixedly installed inside the mounting frame, a bidirectional lead screw fixedly connected to the output end of the adjustment motor, two guide plates symmetrically threaded to the outer wall of the bidirectional lead screw, and an electric push rod provided on the outer side of each of the two guide plates, with a guide frame fixedly connected to one end of the electric push rod, and a limit clamp fixedly installed at the bottom of the guide frame.
[0006] As a preferred embodiment of the above technical solution, both outer walls of the two guide plates are fixedly equipped with protrusions, and the protrusions are slidably connected to the inner wall of the mounting frame. The two limiting clamps are adapted to the size of the polyester staple fiber cloth.
[0007] As a preferred embodiment of the above technical solution, mounting blocks are fixedly installed on the outer walls of both guide plates, and the mounting blocks are fixedly connected to the electric push rod. The outer wall of the guide frame is slidably connected to the inside of the guide plate. A PLC controller is fixedly installed on the outer wall of the cutting protective cover, and a tension sensor is fixedly installed on the outer wall of the cutting protective cover.
[0008] As a preferred embodiment of the above technical solution, the cutting structure includes positioning frames symmetrically installed on both sides of the inner wall of the cutting protective cover, a limit roller is provided between the two positioning frames, a cutting cylinder is fixedly installed on the upper end of each of the two positioning frames, and a guide block is fixedly connected to one end of the cutting cylinder.
[0009] As a preferred embodiment of the above technical solution, a guide slider is fixedly installed on the outer wall of the guide block and the guide slider is slidably connected to the outer wall of the guide rail. A guide post is fixedly installed at the bottom of the guide block and a buffer spring is sleeved on the outer wall of the guide post. The outer wall of the guide post is slidably connected to the inside of the limiting plate. The limiting plate and the outer wall of the guide rail are installed on the outer wall of the positioning frame.
[0010] As a preferred embodiment of the above technical solution, each of the two guide columns is fixedly mounted with an installation plate at one end, and a cutting blade is fixedly mounted at the bottom of the installation plate. Limiting sliders are fixedly mounted at both ends of the installation plate, and the limiting sliders are slidably connected inside the positioning frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with an adjustment structure. The adjustment motor in the drive mounting frame drives the two guide plates on the outer side of the bidirectional lead screw to move relative to each other, causing the two limiting clamps to limit and clamp the polyester staple fiber cloth on both sides. This avoids problems such as positional deviation caused by different sizes of the polyester staple fiber cloth during cutting. When the tension of the polyester staple fiber cloth is insufficient, the electric push rod drives the guide frame to slide along the guide plate, causing the height of the limiting clamps to be adjusted. This is beneficial for adjusting the tension of the polyester staple fiber cloth during cutting and effectively correcting the position of the fiber cloth, avoiding problems such as wrinkles or reduced cutting accuracy caused by insufficient tension during cutting of the polyester staple fiber cloth.
[0012] 2. The device of this utility model is equipped with a cutting structure. By driving the cutting cylinders on the two positioning frames, the guide column on the guide block moves downward. While the guide column moves downward, it squeezes the buffer spring on the limit plate, causing the guide column to drive the cutting blade on the mounting plate to move downward. This effectively buffers the precise cutting of the polyester short fiber cloth on the limit roller, improves the cutting accuracy, and increases the service life of the cutting blade.

It should be understood that the embodiments of the present invention are not limited in scope. Within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications, and equivalents. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5As shown, this embodiment provides a polyester staple fiber cutting device, including a cutting machine table 1. A winding rack 2 is fixedly installed on the upper end of the cutting machine table 1, and a winding motor 3 is fixedly installed on the outer wall of one end of the winding rack 2. A limit frame 4 is fixedly installed on one side of the winding rack 2. A cutting protective cover 6 is fixedly installed on the upper end of the cutting machine table 1. A cutting structure 8 is provided inside the cutting protective cover 6. An adjustment structure 5 is fixedly installed on the outer wall of the cutting protective cover 6. A collection box 9 is provided on one side of the upper end of the cutting machine table 1. The adjustment structure 5 includes a mounting frame 51 fixedly installed on the outer wall of the cutting protective cover 6. An adjustment motor 52 is fixedly installed inside the mounting frame 51. A bidirectional lead screw 53 is fixedly connected to the output end of the adjustment motor 52. Two guide plates 54 are symmetrically threaded to the outer wall of the bidirectional lead screw 53. Electric push rods 58 are provided on the outer side of the two guide plates 54. A guide frame 59 is fixedly connected to one end of the electric push rod 58, and a limit clamp 56 is fixedly installed at the bottom of the guide frame 59.
[0018] like Figures 3 to 4 As shown, protrusions 55 are fixedly installed on both sides of the outer wall of the two guide plates 54, and the protrusions 55 are slidably connected to the inner wall of the mounting frame 51. The two limiting clamps 56 are adapted to the size of the polyester short fiber cloth. Mounting blocks 57 are fixedly installed on the outer wall of the two guide plates 54, and the mounting blocks 57 are fixedly connected to the electric push rod 58. The outer wall of the guide frame 59 is slidably connected to the inside of the guide plate 54. A PLC controller 7 is fixedly installed on the outer wall of the cutting protective cover 6, and a tension sensor 10 is fixedly installed on the outer wall of the cutting protective cover 6.
[0019] When the two guide plates 54 move relative to each other, the two protrusions 55 slide and engage inside the mounting frame 51. At the same time, when the electric push rod 58 drives the limiting clamp 56 on the guide frame 59 to move downward, the tension of the polyester staple fiber cloth is adjusted, which facilitates pre-tightening and avoids problems such as wrinkles or entanglement caused by insufficient tension during cutting.
[0020] like Figure 5 As shown, the cutting structure 8 includes positioning frames 81 symmetrically installed on both sides of the inner wall of the cutting protective cover 6. A limiting roller 893 is provided between the two positioning frames 81. A cutting cylinder 82 is fixedly installed on the upper end of each of the two positioning frames 81. A guide block 83 is fixedly connected to one end of the cutting cylinder 82. A guide slider 84 is fixedly installed on the outer wall of the guide block 83 and is slidably connected to the outer wall of the guide rail 85. A guide post 86 is fixedly installed at the bottom of the guide block 83 and a buffer spring 88 is sleeved on the outer wall of the guide post 86. The outer wall of the guide post 86 is slidably connected to the inside of the limiting plate 87. The limiting plate 87 and the outer wall of the guide rail 85 are installed on the outer wall of the positioning frame 81. An installation plate 89 is fixedly installed at one end of each of the two guide posts 86 and a cutting blade 891 is fixedly installed at the bottom of the installation plate 89. Limiting sliders 892 are fixedly installed at both ends of the installation plate 89 and are slidably connected to the inside of the positioning frame 81.
[0021] When the guide block 83 drives the guide column 86 to move downward, the guide slider 84 slides on the guide rail 85, which facilitates the relatively stable sliding of the guide column 86 within the limiting plate 87. At the same time, the upper end of the guide column 86 is connected to the buffer spring 88, and one end of the buffer spring 88 is in contact with the limiting plate 87, which causes the guide column 86 to drive the cutting blade 891 on the mounting plate 89 to move downward, making the cutting of the polyester staple fiber cloth on the limiting roller 893 relatively stable. Meanwhile, when the mounting plate 89 moves, the two limiting sliders 892 slide within the positioning frame 81, which makes the cutting blade 891 stably cut the polyester staple fiber cloth.
[0022] The working principle and process of this utility model are as follows: The unwinding motor 3 drives the unwinding frame 2 to rotate, causing the polyester staple fiber cloth to pass above the limiting frame 4, with one end threaded through the limiting roller 893. Then, one end of the polyester staple fiber cloth is fixed to the limiting clamp inside the cutting protective cover 6. During cutting, the tension sensor 10 monitors the tension of the polyester staple fiber cloth and compares the data with a pre-set value from the PLC controller 7. Then, the adjusting motor 52 inside the mounting frame 51 drives the two guide plates 54 on the outer side of the bidirectional lead screw 53 to move relative to each other, causing the two limiting clamps 56 to clamp the polyester staple fiber cloth on both sides, preventing positional shifts caused by different sizes of the polyester staple fiber cloth during cutting. When the tension of the polyester staple fiber cloth is insufficient... During the cutting process, the electric push rod 58 drives the guide frame 59 to slide along the guide plate 54, thereby adjusting the height of the limiting clamp 56. This adjusts the tension of the polyester staple fiber cloth during cutting, preventing wrinkles or reduced cutting accuracy caused by insufficient tension. After the polyester staple fiber cloth is pre-tensioned, the cutting cylinders 82 on the two positioning frames 81 drive the guide column 86 on the guide block 83 to move downward. As the guide column 86 moves downward, it squeezes the buffer spring 88 on the limiting plate 87, causing the guide column 86 to drive the cutting blade 891 on the mounting plate 89 to move downward. This effectively buffers the polyester staple fiber cloth on the limiting roller 893 during precise cutting, protecting the cutting blade 891. The cut polyester staple fiber cloth falls into the collection box 9 for unified collection.
