Problems solved by technology

Before measuring the strength of cotton short fibers, it is necessary to comb the short fibers to make the fibers stretch into fiber bundles, so that the two ends of the fiber bundles can be clamped and fixed later, so as to facilitate the tensile test of the fibers. In this stage, cotton short fiber is usually manually combed. This method is not convenient to operate and wastes manpower and material resources. Therefore, a pre-processing equipment for measuring the strength of cotton short fiber is designed to solve the above problems.

Embodiment 1

[0030] see Figure 1-6 , cotton staple fiber strength measurement pre-processing equipment, including a substrate 1, the top surface of the substrate 1 is used to place the cotton staple fiber to be processed, the middle part of the top surface of the substrate 1 is provided with a pressing mechanism 7, the top surface of the substrate 1 is two A carding mechanism 5 is arranged symmetrically on the side.

[0031] Since the cotton short fiber needs to be combed into a neat fiber bundle before measuring its strength, the carding effect can be improved by fixing the middle part of the cotton short fiber and reciprocatingly combing from the middle part to both sides, and avoid fixing the cotton fiber from one end. Due to the unequal length of cotton fibers, some cotton fibers are not fixed, so when carding, the unfixed short cotton fibers will be reciprocated by the carding mechanism to form a ball, which brings inconvenience to use.

[0032] A driving mechanism is also provided ...

Embodiment 2

[0042] In the above-mentioned embodiment, there is also the following problem, that is, the slider 10 moves in the first groove 42. When the side near the transition groove 44 moves to the other side, the slider may directly move from the first groove 44 to the other side. 42 enters into the transition channel one 44, causing the upper sliding rod 62 to move up, so that the carding plate 14 cannot contact the short cotton fibers on the substrate 1, and the purpose of carding cannot be realized. Therefore, in this scheme, please refer to image 3 as well as Figure 5 A one-way limit mechanism is also provided at the connection between the first transition channel 44 and the first channel 42 to prevent the slider 10 from directly moving from the first channel 42 to the first transition channel 44 .

[0043] The one-way limiting mechanism includes a guide limiting plate 12 that is rotatably connected to the inner wall of the transition channel one 44, and one side of the guide li...

Abstract

The invention relates to the technical field of cotton fiber processing, and discloses cotton short fiber strength measurement pretreatment equipment. The cotton short fiber strength measurement pretreatment equipment comprises a base plate, the top face of the base plate is used for containing cotton short fibers to be treated, a pressing mechanism is arranged in the middle of the top face of the base plate, and carding mechanisms are symmetrically arranged on the two sides of the top face of the base plate. A driving mechanism is further arranged on the side face of the base plate so as to drive the carding mechanisms on the two sides to be away from or close to the pressing mechanism, the pressing mechanism comprises a first fixing block, a second fixing block and a rotary pressing plate, wherein the first fixing block and the second fixing block are correspondingly fixed to the two sides of the base plate, the rotary pressing plate is installed between the first fixing block and the second fixing block, one end of the rotary pressing plate is connected with the first fixing block through a pin shaft, and the other end of the rotary pressing plate is detachably connected with the second fixing block directly through a screw. Compared with manual short fiber carding, the carding efficiency is higher, the effect is better, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cotton fiber processing, in particular to pre-processing equipment for measuring the strength of short cotton fibers. Background technique [0002] Strength is the maximum stress of a material in the process of fracture failure, which plays a pivotal role in fracture mechanics. At the current stage of fiber strength testing, the fiber is generally pulled with a rope, and the stretched length when the limit is broken is recorded to judge the strength of the fiber. Before measuring the strength of cotton short fibers, it is necessary to comb the short fibers to make the fibers stretch into fiber bundles, so that the two ends of the fiber bundles can be clamped and fixed later, so as to facilitate the tensile test of the fibers. Cotton short fiber is usually manually combed in the stage. This method is not convenient to operate and wastes manpower and material resources. Therefore, a pre-processing equipmen...
