Background

The quality of the cotton fiber, which is a raw material in the textile industry, directly affects the quality and yield of the textile. The analysis items of the cotton fiber quality include fiber length, fiber strength, and the like.

When the quality of the cotton fiber is detected, a cotton fiber sample is needed, in the standardized detection process, the input of the original sample to be detected is relatively stable, the sample is a cotton ball of about 120g-150g, and the cotton ball is formed after the original picked cotton is subjected to simple cotton fluffing treatment and cannot have a cut or a cut fracture. The external dimension is about 100 multiplied by 260 multiplied by 100 (mm); the mode of obtaining the sample at the present stage is manual splitting, but the manual splitting efficiency is low, and the requirement of rapid detection is difficult to meet.

In the patent, a sample is directly taken out from the middle of a large sample through the large pressure of a pressing cylinder, the required pressure is very large, the cotton fiber is broken due to too large pressure, the split sample fiber is torn and broken, and therefore the detection data is inaccurate; and through pushing down cylinder cooperation dial from sample middle part split play sample, the mode that the sample was acquireed to the formula of pushing down leans on pressure directly to push away a group of cotton fiber from the centre is hard, does not go out to press many times, has the sample split unclean, leads to sample quality not enough to the condition of big sample, little sample appears easily when leading to long strong detection, in case big sample, little sample appear frequently, can lead to single sample repeated detection, detection time substantially increases, influences the efficiency that detects. Meanwhile, the detection is carried out by blowing strong wind into the detection port, and the conveying by blowing strong wind has difficulty in ensuring the position of the sample fed into the detection port.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, the cotton fiber sample splitting mechanism comprises a sample box 1 and two clamping assemblies 2 arranged in a mirror image manner, wherein the two clamping assemblies 2 can move oppositely or back to back in the horizontal direction at the same time and are positioned at two sides of the sample box 1; thereby realize that two centre gripping subassemblies 2 tear both sides after following the cotton fiber sample of centre gripping in the sample box 1 simultaneously, make its separation for possess naturally tear two of mouthful examine length and intensity detection sample. In fig. 1, in order to show different working states of the clamping assembly 2, the left clamping assembly 2 is in a clamping state, and the right clamping assembly 2 is in an unclamping state.

As shown in fig. 2, the sample box 1 is a housing structure with a U-shaped vertical cross section, the top surface and both ends in the length direction are empty, the bottom surface includes a plurality of strip grooves 11 formed along the length direction, the strip grooves 11 are in a vertical penetrating structure, but the strip grooves 11 at both ends are not communicated, the strip grooves 11 at both ends are also symmetrically arranged, in this embodiment, ten strip grooves 11 are totally distributed, ten strip grooves 11 are uniformly distributed at both ends of the sample box 1, and as can be seen from one end, the width of the strip grooves 11 at both sides is greater than that of the strip groove 11 at the middle part in the width direction; referring to fig. 6, this is because the two side wide elongated slots 11 need to accommodate two rows of first needles 25 located at the outermost sides, and the middle elongated slot 11 needs to accommodate only one row of first needles 25. The cotton fiber sample is close to the sample box 1 in the length and width directions, and when the cotton fiber sample is placed, the sample is uniformly and flatly paved in the sample box 1.

Since the clamping members 2 on both sides have the same structure, the embodiment will be described by taking one clamping member 2 as an example. As shown in fig. 3, the clamping assembly 2 includes a base plate 21, a clamping plate driving member, a first clamping plate 23, a second clamping plate 24, a first needle 25, a second needle 26, a first needle hole plate 27, and a second needle hole plate 28. The clamp driving member is a clamp cylinder 22 for driving the first clamp 23 and the second clamp 24 to move up and down, and the clamp driving member may also be other mechanisms capable of realizing up-and-down reciprocating motion, such as a lead screw and nut mechanism, a hydraulic cylinder, and the like.

The base plate 21 is two, and two base plates 21 are arranged along the horizontal plane symmetry from top to bottom, as shown in fig. 4, and a 90 degree tilting mechanism is all connected on two base plate 21's right side, and this 90 degree tilting mechanism is for opening and shutting cylinder 6, and two cylinders 6 that open and shut can realize that two base plates 21 open and close. At the beginning of work, the opening and closing cylinder 6 acts to rotate the substrate 21 at the upper part clockwise and rotate the substrate 21 at the lower part anticlockwise, so that the clamping assembly 2 is opened like a tiger's mouth, and then the clamping assembly 2 is closed when the clamping position is reached, and as shown in fig. 4, the two substrates 21 are in a parallel state.

The first needle 25 and the second needle 26 correspond to the position of the elongated slot 11 in the horizontal direction, namely: including the first needle 25 and the second needle 26 corresponding to the position of the long groove 11, in this embodiment, the first needle 25 is shorter and the first needle plate 27 is limited, so the first needle 25 is not inserted into the long groove 11, and only the second needle 26 can pass through the long groove 11 from the bottom of the sample box 1.

As shown in fig. 5, the first pinhole plate 27 is bent downward along two sides of the sample box 1 in the longitudinal direction to form a first folding edge 271, and the second pinhole plate 28 is bent upward along two sides of the sample box 1 in the longitudinal direction to form a second folding edge 281. The first folding edge 271 and the second folding edge 281 can play a role in supporting cotton fibers, and reduce the extrusion of the cotton fibers and the sample box 1. The cotton fiber is prevented from being pressed, the friction force is larger on the whole after compaction and interlacing, the tearing is more difficult, the broken fiber is more easily generated, and the cotton fiber sample can be fixed by the first needle tool 25 and the second needle tool 26 on the outermost sides in the transportation process.
