Description

Technical Field

[0001] This utility model relates to the field of cotton fiber testing technology, and in particular to a cotton fiber strength testing device. Background Technology

[0002] Cotton fiber is the main raw material of my country's textile industry and occupies a very important position in textile fibers. my country is one of the world's major cotton-producing countries. After newly cultivated cotton varieties are planted and harvested, it is necessary to test the strength of the cotton fibers of the new varieties. The strength of cotton fibers is one of the necessary conditions for the fibers to have spinning performance and use value. The higher the fiber strength, the higher the yarn strength will be. Therefore, it is necessary to test the strength of cotton fibers to judge the strength of cotton fibers.

[0003] After testing the cotton fiber strength using the testing device, it is necessary to clean the cotton fibers remaining in the clamp jaws. Since the existing cotton fiber strength testing device does not have an automatic cleaning function, manual cleaning is required after each test, which increases the workload of the staff. Moreover, if cleaning is forgotten, the residual cotton fibers can easily scatter to various corners of the testing device, causing the testing device to become dirty. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the inability to automatically clean the clamps in the prior art, and to propose a cotton fiber strength testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cotton fiber strength testing device includes two sets of clamping components for clamping cotton fibers. The two sets of clamping components are respectively disposed on the sides of two upright plates and are arranged opposite to each other. One set of clamping components and the upright plates are moved on the surface of the box by a displacement component. The upper surface of the box is provided with a cleaning component for cleaning multiple clamping plates, and the cleaning component is disposed between the two sets of clamping components.

[0007] In some embodiments, the clamping assembly includes two opposing movable frames, both of which are stepped. The lower movable frame is fixed to the side of the upright plate, and two guide rods are fixedly connected to the upper surface of the lower movable frame. The upper movable frame slides on the surfaces of the two guide rods and is driven to slide on the surfaces of the two guide rods by a threaded rod.

[0008] In some embodiments, the displacement assembly includes a threaded column that rotates inside the housing, a displacement plate that is threadedly connected to the surface of the threaded column, the upper end of the displacement plate extending out of the upper surface of the housing, and a tension sensor fixed between the upper end of the displacement plate and the sliding upright plate.

[0009] In some embodiments, the cleaning assembly includes a guide rail fixed to the upper surface of the housing and a slide that slides on the surface of the guide rail. A dual-head motor is provided inside the slide. Both ends of the two output shafts of the dual-head motor extend from both sides of the slide and are respectively fixed with roller brushes. The height of the two roller brushes is located at the middle of the maximum distance between the upper and lower moving frames.

[0010] In some embodiments, a dust collection assembly is provided inside the housing. The dust collection assembly includes a dust collection hood fixed to the side of the two uprights away from the clamping assembly and a storage box fixed inside the housing. The two dust collection hoods are respectively connected to the storage box through two hoses.

[0011] In some embodiments, a scale for observing the movement distance of the displacement plate is fixed on the upper surface of the housing.

[0012] Compared with the prior art, the present invention provides a cotton fiber strength testing device, which has the following beneficial effects.

[0013] 1. This utility model, by setting up a cleaning component, allows the roller brush to rotate and move simultaneously on the surface of the clamping plate, thereby wrapping the residual cotton fibers on the surface of the clamping plate around the surface of the roller brush, achieving the purpose of automatic cleaning.

[0014] 2. This utility model, by setting up a dust collection component, creates negative pressure in the two dust collection hoods to extract cotton fibers floating near the clamping component and store them in the storage box. Regular cleaning is then performed to prevent cotton fibers thrown out by the rotating brush from remaining on the surface of the box.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A cotton fiber strength testing device includes two sets of clamping components 3 for clamping cotton fibers. The two sets of clamping components 3 are respectively disposed on the sides of two upright plates 2 and are arranged opposite to each other. One set of clamping components 3 and the upright plates 2 move on the surface of a housing 1 via a displacement component 4. The clamping components 3 include two oppositely arranged movable frames 301, both of which are stepped. The lower movable frame 301 is fixed to the side of the upright plate 2, and two guide rods 302 are fixedly connected to the upper surface of the lower movable frame 301. The upper movable frame 301 slides on the surface of the two guide rods 302. The upper ends of the two guide rods 302 are... A limit shaft is provided. A threaded rod 303 is threadedly connected to the surface of the upper movable frame 301. A handle is fixed to the upper end of the threaded rod 303. The lower end of the threaded rod 303 rotates on the surface of the lower movable frame 301 through a bearing. The two movable frames 301 are far apart from each other at the end near the vertical plate 2, and close together at the end away from the vertical plate 2. The threaded column 401 and the two guide rods 302 are both located at the far ends of the two movable frames 301. Clamping plates 304 are fixed to the opposite surfaces of the two movable frames 301. The two clamping plates 304 are located at the close ends of the two movable frames 301, and rounded corners are provided on both sides of the two clamping plates 304.

[0026] It is understandable that the screw rod 303 is rotated by the handle, which causes the upper moving frame 301 to slide downward on the surface of the two guide rods 302, so that the clamping plates 304 on the surface of the two moving frames 301 come into contact and clamp and fix the cotton fibers. With the help of the rounded corners, the edges of the clamping plates 304 are prevented from damaging the cotton fibers during the clamping process, thus affecting the strength test results. By setting the moving frame 301 to a stepped shape and making the ends that are far apart face the upright plate 2, the dust collection cover 601 on the surface of the upright plate 2 can be avoided.

[0027] Specifically, one of the upright plates 2 is fixed to the upper surface of the housing 1, and the other upright plate 2 slides on the upper surface of the housing 1. The displacement assembly 4 includes a threaded post 401 that rotates inside the housing 1. A displacement plate 402 is threadedly connected to the surface of the threaded post 401. The upper end of the displacement plate 402 extends out of the upper surface of the housing 1. A tension sensor 403 is fixed between the upper end of the displacement plate 402 and the sliding upright plate 2. A through groove for the displacement plate 402 to slide is opened on the upper surface of the housing 1. The threaded post 401 is driven to rotate by a drive motor.

[0028] It is understandable that the drive motor drives the threaded column 401 to rotate, thereby moving the displacement plate 402 and the sliding vertical plate 2, thereby moving the clamping assembly 3 away from the other clamping assembly 3, pulling the cotton fiber, and detecting the strength of the cotton fiber under the action of the tension sensor 403.

[0029] Specifically, the upper surface of the housing 1 is provided with a cleaning assembly 5 for cleaning multiple clamping plates 304. The cleaning assembly 5 is located between two sets of clamping assemblies 3. The cleaning assembly 5 includes a guide rail 501 fixed to the upper surface of the housing 1 and a slide 502 that slides on the surface of the guide rail 501. A storage cavity is opened on the upper surface of the slide 502. A dual-head motor 503 is installed inside the storage cavity. The two output shafts of the dual-head motor 503 extend from both sides of the slide 502 and are respectively fixed with roller brushes 504. The height of the two roller brushes 504 is located in the middle of the maximum distance between the upper moving frame 301 and the lower moving frame 301. The slide 502 is driven to slide by an electric push rod. The tail end of the electric push rod is fixed to the back of the housing 1.

[0030] Understandably, the electric push rod drives the carriage 502 to slide on the surface of the guide rail 501 toward the two clamping components 3. At the same time, the dual-head motor 503 drives the two roller brushes 504 to rotate, causing the roller brushes 504 to rotate and move simultaneously on the surface of the clamping plate 304. This removes residual cotton fibers from the surface of the clamping plate 304 and wraps them around the surface of the roller brushes 504, achieving automatic cleaning. The cotton fibers on the surface of the roller brushes 504 can be cleaned periodically, reducing the number of manual cleanings and lowering the workload.

[0031] Specifically, a dust collection assembly 6 is installed inside the housing 1. The dust collection assembly 6 includes dust collection hoods 601 that are fixed to the side of the two upright plates 2 away from the clamping assembly 3. A storage box 602 is fixed inside the housing 1. The two dust collection hoods 601 are connected to the storage box 602 through two hoses. A filter valve 603 is connected to the back of the storage box 602. The other end of the filter valve 603 is connected to a vacuum pump for evacuating the storage box 602. A sealing cover is hinged to the side of the storage box 602. A vent is provided on the back of the housing 1.

[0032] Understandably, by operating the vacuum pump, air is drawn from the storage tank 602 to create negative pressure. Under the action of the two hoses, negative pressure is created in the two dust collection hoods 601, which extract the cotton fibers floating near the clamping assembly 3 and store them in the storage tank 602. The tank is cleaned periodically, and the filter valve 603 prevents the cotton fibers from entering the vacuum pump.

[0033] Specifically, a scale 7 for observing the movement distance of the displacement plate 402 is fixed on the upper surface of the box 1, and a protective cover 8 is hinged to the back of the box 1.

[0034] It is understandable that by setting the scale 7, it is easy to observe the movement distance of the displacement plate 402, and by setting the protective cover 8, it can protect the detection device when it is not in use, and at the same time, achieve the purpose of dust prevention.

[0035] In this invention, the two ends of the prepared cotton fibers are placed on two sets of clamping assemblies 3. A rotating handle drives the threaded rod 303 to rotate, causing the upper moving frame 301 to slide downwards on the surfaces of the two guide rods 302. This causes the clamping plates 304 on the surfaces of the two moving frames 301 to contact and clamp the cotton fibers. Then, a drive motor drives the threaded column 401 to rotate, causing the displacement plate 402 and the sliding upright plate 2 to move, moving one clamping assembly 3 away from the other and pulling the cotton fibers. Under the action of the tension sensor 403, the detection device detects the strength of the cotton fibers. After the detection is completed, the clamping assembly 3 is released, and the broken cotton fibers are removed. Then, under the action of the scale 7, the displacement... The plate 402 moves to a position to engage with the roller brush 504. An electric push rod operates, causing the carriage 502 to move the roller brush 504 towards the two clamping components 3. Simultaneously, the dual-head motor 503 operates, driving the two roller brushes 504 to rotate. The roller brushes 504 rotate and move simultaneously on the surface of the clamping plate 304, thus wrapping the residual cotton fibers on the surface of the clamping plate 304 around the surface of the roller brushes 504, achieving automatic cleaning. While cleaning the clamping plate 304, a vacuum pump operates, creating negative pressure in the storage box 602. This negative pressure in the two dust hoods 601 extracts the cotton fibers floating near the clamping components 3 and stores them in the storage box 602, preventing cotton fibers thrown out by the rotating roller brush 504 from remaining on the surface of the box 1, thus improving the cleaning effect.
