Technical Field
[0001] The present application relates to the technical field of cotton processing, and in particular to an auxiliary sampling device for cotton fibers. Background Art
[0002] The length of cotton fibers is one of the important indicators for measuring the quality of cotton, which has a direct impact on the processing of cotton and the quality of the final products. Therefore, it is necessary to measure the length of cotton fibers in the laboratory, and for this purpose, some sample fibers need to be taken out from the cotton for length detection.
[0003] Currently, in order to improve the sampling efficiency and accuracy, existing automation technologies have realized the automatic sampling of cotton fibers by using devices such as robotic arms, conveyor belts, and sensors. These automated devices can reduce manual operations to a certain extent and improve the sampling speed and consistency. For example, some cotton sampling devices can identify the starting point of the fibers through image recognition technology and automatically adjust the sampling position to ensure the representativeness of the sampling.
[0004] However, the above-mentioned related technologies have the following problems: existing cotton sampling devices still have deficiencies in taking out straight cotton fibers for measuring the fiber length in the laboratory, and it is difficult to precisely control the orientation and arrangement of the fibers, resulting in the fibers being prone to curling or overlapping after sampling, which easily affects the accuracy of the measurement results. Summary of the Utility Model
[0005] In order to address the deficiencies of the existing technology, the present application provides an auxiliary sampling device for cotton fibers, which can reduce the occurrence of curling or overlapping of the sampled cotton fibers for more accurate fiber length detection.
[0006] The present application provides an auxiliary sampling device for cotton fibers by adopting the following technical solutions:
[0007] An auxiliary sampling device for cotton fibers includes a bracket. A cotton placing cylinder is provided at the top of the bracket. An cotton taking member for taking out cotton and adsorbing the taken-out cotton is provided outside the cotton placing cylinder.

A rotating arm is rotatably connected to one end of the cotton placing cylinder close to the bracket, and a carding member is provided at the end of the rotating arm far from the connection with the cotton placing cylinder, and the carding member abuts against the outer side of the carding net.
[0008] By adopting the above technical solutions, cotton is placed in the cotton placing cylinder. The rotating arm drives the carding member to rotate around the cotton placing cylinder. The carding member extracts cotton fibers from the cotton taking member and brings them to the outer side of the carding net. The carding net hooks the fibers, and the carding member continues to rotate, taking away the adhered fibers while straightening the curled cotton fibers, reducing the occurrence of curling or overlapping of the sampled cotton fibers for precise fiber length detection.
[0009] The present application further provides: the cotton taking component also includes a cotton taking arc plate, the end side of the cotton taking arc plate is connected to the end side of the cotton combing net to form a cotton placing cavity of the cotton placing cylinder, the cotton combing component abuts against the outer side surface of the cotton taking arc plate, and the cotton taking arc plate is provided with a plurality of circular holes.
[0010] By adopting the above technical solution, the cotton combing part hooks out the cotton located in the cotton cavity through the several circular holes of the cotton taking arc plate, and the amount of cotton samples taken out from the several circular holes will be smaller, which meets the requirements of laboratory testing of cotton fiber length and reduces waste.
[0011] The present application further arranges: the cotton combing part includes a connecting arm and a cotton picking comb, one end of the connecting arm is fixedly connected to the end of the rotating arm away from the connection with the cotton placing cylinder, a mounting groove is provided on the top of the connecting arm, the cotton picking comb is slidably connected in the mounting groove of the connecting arm, and the cotton combed by the cotton picking comb abuts against the outer side surfaces of the cotton picking arc plate and the cotton combing net.
[0012] By adopting the above technical solution, the cotton taking comb with straight cotton adhered to it can be taken out from the connecting arm, which is convenient for fiber length detection.
[0013] The present application further provides that: a clamping block is provided at one end of the cotton picking comb, and the clamping block is clamped in a clamping groove at one end of the connecting arm away from the rotating arm.
[0014] By adopting the above technical solution, the clamping block is clamped in the clamping groove of the connecting arm when the cotton picking comb is working, so that the cotton picking comb can be stably fixed in the installation groove of the connecting arm.
[0015] The present application further provides that: a boss is provided at the bottom of the cotton taking arc plate located in the cotton placing cavity of the cotton placing cylinder.
[0016] By adopting the above technical solution, when sampling, the cotton is tightly attached to the inner side of the cotton taking arc plate on the top of the boss, and the boss can hold the cotton that tends to fall, so that the cotton can be as close to the inner side of the cotton taking arc plate as possible, thereby improving the efficiency of cotton sampling.
[0017] The present application further provides that: protective rings are provided at both ends of the cotton placing tube.
[0018] By adopting the above technical solution, the protective ring can avoid as much as possible the cotton fibers on the top of the cotton taking arc plate and the cotton combing net from falling out.
[0019] The present application further provides that: the protective ring at one end of the cotton placing tube away from the bracket is integrally formed with a cotton blocking ring toward the center of the cotton placing tube.
[0020] By adopting the above technical solution, the cotton retaining ring can avoid the cotton fibers in the cotton placement cavity from falling out as much as possible.
[0021] The present application is further configured such that a lock catch is provided at one end of the cotton placing cylinder away from the support, and a locking member adapted to the lock catch is provided at one end of the connecting arm away from the rotating arm.
[0022] By adopting the above technical solution, when the carding member is not in use, the lock catch locks the locking member, thereby being able to lock the connecting arm and prevent the rotation of the connecting arm.
[0023] In summary, the present application has the following beneficial effects:
[0024] In the present application, cotton needs to be first placed into the cotton placing cavity of the cotton placing cylinder. The rotating arm drives the carding member to rotate around the cotton placing cylinder. The carding member takes out cotton fibers from the cotton taking member and brings the cotton fibers to the outer side of the carding net. The carding net can effectively hook the cotton fibers. As the carding member rotates along the outer side of the carding net, it takes away the cotton fibers adhering to the net surface and further straightens the cotton fibers to reduce the phenomenon of curling or overlapping of the cotton fibers after sampling, which helps to ensure that the sampled cotton fibers are straighter when performing fiber length detection, thereby improving the accuracy of fiber length detection.

Detailed Description of the Embodiment
[0030] The following further describes the present application in detail Figures 1 to 4 with reference to the attached drawings.
[0031] Reference Figure 1 to Figure 2, in this embodiment, a cotton fiber auxiliary sampling device includes a bracket 1. A cotton placing cylinder 2 is fixedly connected to the top of the bracket 1. Cotton is placed in the cotton placing cylinder 2. A cotton picking member 3 is arranged outside the cotton placing cylinder 2. The cotton picking member 3 is used to pick out cotton and adsorb the picked cotton. The cotton picking member 3 includes a carding net 30. The carding net 30 is located on the outer side of the cotton placing cylinder 2. One end of the cotton placing cylinder 2 close to the bracket 1 is rotatably connected to a rotating arm 4. A carding member 5 is fixedly connected to the end of the rotating arm 4 away from the connection with the cotton placing cylinder 2. The carding member 5 abuts against the outer side of the carding net 30. The rotating arm 4 drives the carding member 5 to rotate around the cotton placing cylinder 2. After the carding member picks out cotton fibers from the cotton picking member 3, the picked cotton fibers are brought to the outer side of the carding net 30 by the carding member 5. The cotton fibers have a certain length and flexibility and can be hooked by the mesh holes or entangled on the surface of the carding net 30. And the carding member 5 continues to rotate along the outer side of the carding net 30 with the cotton fibers. Since the carding net 30 has a certain adsorption force on the cotton fibers, when the cotton fibers are taken away by the carding member 5 with greater friction, the curled or overlapped cotton fibers can be straightened for more accurate fiber length detection.
[0032] Reference Figures 1 to 3 , in this embodiment, the cotton picking member 3 further includes a cotton picking arc plate 31. The end side of the cotton picking arc plate 31 is connected to the end side of the carding net 30 to form a cotton placing cavity of the cotton placing cylinder 2. Preferably, the area of the cotton picking arc plate 31 on the outer side of the cotton placing cylinder 2 is the same as the area of the carding net 30 on the cotton placing cylinder 2, that is, the cotton picking arc plate 31 and the carding net 30 each account for half of the area of the outer side of the cotton placing cylinder 2. The carding member 5 abuts against the outer side of the cotton picking arc plate 31. The cotton picking arc plate 31 is provided with a plurality of round holes. In the actual use process, the user needs to abut the cotton against the inner side of the cotton picking arc plate 31 of the cotton placing cavity to expose the cotton and make it enter the round holes of the cotton picking arc plate 31, so that the carding member 5 can hook out the cotton located in the cotton placing cavity from the plurality of round holes of the cotton picking arc plate 31. And since the round holes limit the amount of cotton taken out by the carding member 5 in the cotton placing cavity, it meets the requirements for laboratory detection of cotton fiber length and saves the amount of extra cotton fibers taken out from the cotton.
[0033] Reference Figure 1 and Figure 4, in this embodiment, the carding member 5 includes a connecting arm 50 and a cotton-taking comb 51. One end of the connecting arm 50 is fixedly connected to the end of the rotating arm 4 away from the end connected to the cotton placing cylinder 2. A handle is fixedly connected to the end of the connecting arm 50 away from the end connected to the cotton placing cylinder 2, which is convenient for the user to grip. An installation groove is formed at the top of the connecting arm 50. The cotton-taking comb 51 is slidably connected to the installation groove of the connecting arm 50. Since cotton fibers have a certain length and flexibility, the carding of the cotton-taking comb 51 has several steel bars, and the cotton fibers can hook or entangle on the densely distributed steel bars, so as to take out the cotton fibers from several round holes of the cotton-taking arc plate 31. After the cotton fibers are straightened on the carding net 30, the cotton-taking comb 51 adhered with straight cotton can be separately taken out from the connecting arm 50 for subsequent fiber length detection.
[0034] Furthermore, a clamping block 510 is fixedly connected to one end of the cotton-taking comb 51. The clamping block 510 is clamped in the clamping groove at the end of the connecting arm 50 away from the rotating arm 4. When the cotton-taking comb 51 is rotated by the rotating arm 4, the clamping block 510 is clamped in the clamping groove of the connecting arm 50, and it is difficult for the cotton-taking comb 51 to fall out of the installation groove of the connecting arm 50, so that the cotton-taking work runs stably.
[0035] Still further, a convex platform 6 is fixedly connected to the bottom of the cotton-taking arc plate 31 in the cotton placing cavity of the cotton placing cylinder 2. Specifically, the convex platform 6 forms a plane towards the top of the cotton-taking arc plate 31, which is used to support the cotton with a tendency to fall off the cotton-taking arc plate 31, so that the cotton can be concentrated on the inner side of the cotton-taking arc plate 31 as much as possible, improving the efficiency of cotton sampling.
[0036] In addition, protective rings 7 are provided around both ends of the cotton placing cylinder 2. The protective rings 7 form a height difference with the outer sides of the cotton-taking arc plate 31 and the carding net 30, and the protective rings 7 are higher than the outer sides of the cotton-taking arc plate 31 and the carding net 30, so as to reduce the possibility of cotton fibers on the tops of the cotton-taking arc plate 31 and the carding net 30 falling outside.
[0037] Furthermore, a cotton blocking ring 8 is integrally formed towards the center of the cotton placing cylinder 2 at the protective ring 7 at the end of the cotton placing cylinder 2 away from the bracket 1. The cotton blocking ring 8 forms a height difference with the outer sides of the cotton-taking arc plate 31 and the carding net 30 in the cotton placing cavity, and the cotton blocking ring 8 is higher than the inner sides of the cotton-taking arc plate 31 and the carding net 30 in the cotton placing cavity, so as to reduce the possibility of cotton fibers in the cotton placing cavity falling outside.
[0038] Still further, a lock 9 is provided at the end of the cotton placing cylinder 2 away from the bracket 1, and a locking member adapted to the lock 9 is provided at the end of the connecting arm 50 away from the rotating arm 4. When the carding member 5 is not in use, the lock 9 locks the locking member of the connecting arm 50, and thus the connecting arm 50 can be locked so that the connecting arm 50 cannot rotate any more.
[0039] The implementation principle of the embodiment of this application is as follows: The user puts cotton into the cotton placement cavity of the cotton placement cylinder 2, presses the cotton against the inner side surface of the cotton picking arc plate 31, rotates the rotating arm 4, so that the connecting arm 50 drives the cotton picking comb 51 to take out cotton fibers through several round holes of the cotton picking arc plate 31 to the outer side surface of the cotton picking arc plate 31. The cotton fibers adhere to the cotton picking comb 51 and are rotated to the outer side surface of the carding net 30. The adsorption of the outer side surface of the carding net 30 on the cotton fibers causes the cotton fibers on the outer side surface of the carding net 30 to be flattened and taken away from the carding net 30 when the cotton picking comb 51 rotates around the cotton placement cylinder 2, thereby reducing the occurrence of curling or overlapping of the sampled cotton fibers and enabling more accurate fiber length detection.
[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered by the protection scope of this application.
