Description

Technical Field

[0001] This utility model relates to the field of fiber sampling technology, and in particular to a sampling device for BCF fiber detection. Background Technology

[0002] As a core raw material for carpets, home textiles, etc., the performance testing of BCF fiber depends on the complete preservation of the original crimp structure of the fiber during the sampling process. In the BCF fiber raw material stage, continuous BCF fiber filaments are tightly wound onto paper or plastic filament tubes. When sampling, the fiber filaments must first be drawn out from the filament tube and then a fixed length that meets the testing requirements is cut off.

[0003] Currently, BCF fiber filament sampling is mostly done manually or with simple tools. When sampling manually, the operator needs to rotate the filament drum with one hand to release the fiber filament, and lay the pulled-out filament flat on the work surface with the other hand. Finally, the filament is cut with scissors or a utility knife. When sampling with simple tools, the fiber filament is also pulled out. In order to facilitate cutting, the fiber filament still needs to be laid flat on the work surface and cut while keeping the fiber filament horizontal. Whether it is manual operation or simple tool operation, the friction between the fiber filament and the work surface when it is laid flat and the lateral force during traction can easily crush or flatten the three-dimensional crimped structure of the fiber, making it difficult to guarantee the stability of the fiber filament.

[0004] Therefore, based on the above situation, it is necessary to design a sampling device for BCF fiber detection to solve the above problems. Utility Model Content

[0005] This invention provides a sampling device for BCF fiber testing to solve the problems of pulling, crushing and flattening the crimped structure of fiber filaments in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A sampling device for BCF fiber testing includes a base, characterized in that a support frame is provided on the base, and a first clamping member and a second clamping member are provided on the support frame along its vertical coaxial direction for clamping and fixing the fiber filament in a naturally hanging state, the second clamping member is located above the first clamping member and is slidably connected to the support frame, and a cutting component for cutting the fiber filament is provided above the second clamping member.

[0008] Preferably, both the first clamping member and the second clamping member are elastic clamps, the clamping end of the elastic clamp is provided with a clamping surface for clamping fiber filaments, and the operating end of the elastic clamp is provided with a spring.

[0009] Preferably, the cutting assembly includes a sliding plate and a cutting blade slidably connected to the sliding plate, a spring connecting the cutting blade and the sliding plate, and a sleeve slidably sleeved on the support frame connected to the second clamping member, with the sliding plate disposed on the sleeve.

[0010] Preferably, a locking screw is threaded onto the sleeve, which is used to fix the position of the second clamping member and the cutting assembly when one end of the locking screw is in close contact with the support frame.

[0011] Preferably, the base has a sliding groove, and the support frame is damped and slidably connected to the base.

[0012] Preferably, the support frame is provided with scale lines to assist in calibrating the sliding position of the second clamping member, so as to achieve fixed-length cutting of fiber filaments.

[0013] The beneficial effects of this utility model are as follows: by setting the first clamping member and the second clamping member coaxially along the vertical axis, and sliding the second clamping member to change the distance between it and the first clamping member, the fiber filament is clamped and fixed in a natural hanging state, which reduces the squeezing and pulling force generated by the traditional horizontal flat clamping, and can completely preserve the three-dimensional crimped shape of the sampled fiber filament, ensuring that the subsequent test data can truly reflect the fiber performance.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-4 As shown, a sampling device for BCF fiber testing includes a base 1, on which a support frame 2 is mounted. The support frame 2 is vertical, and a first clamping member 3 and a second clamping member 4 are coaxially mounted on the support frame 2 along its vertical axis. When sampling fiber filaments, the fiber filaments are drawn out from the spool, allowing them to hang naturally. The first clamping member 3 and the second clamping member 4 then collaboratively clamp and fix the naturally hanging fiber filaments. During operation, since the position of the first clamping member 3 on the support frame 2 is fixed, the first clamping member 3 is used to clamp and fix the fiber filaments. The outer wall is initially fixed by bonding. Then, according to the sampling length requirements, the position of the second clamping member 4 is adjusted by sliding along the support frame 2. The vertical distance between the first clamping member 3 and the second clamping member 4 is adjusted. After the preset length is reached, the second clamping member 4 clamps and fixes the fiber filament, completing the fixation of the upper and lower ends of the fiber filament. At this time, the fiber filament is stably clamped under the action of double clamping. Finally, the cutting component 5 located above the second clamping member 4 cuts the fiber filament above the second clamping member 4. There is no lateral compression or friction during the entire sampling process, and the original three-dimensional crimped structure of the fiber filament is completely preserved.

[0022] Reference Figure 4 As shown, both the first clamping member 3 and the second clamping member 4 are elastic clamps. The clamping end of the elastic clamp is provided with a clamping surface for clamping the fiber filament. The elastic clamp can be a large A-clamp as in the prior art, consisting of two clamping arms. The two clamping arms are connected together by a fixed rivet or screw. This connection point is equivalent to the fulcrum of a lever. When an external force is applied to the operating end of the clamping arm, the clamping arm will rotate around the fulcrum, causing the clamping ends to move closer together or further apart to relax. When clamping the fiber filament, the operating ends of the two clamping arms are squeezed, and the spring 6 between the two clamping arms is deformed. When the two clamping arms are relaxed, the clamping end clamps the fiber filament under the elastic action of the spring 6. In actual use, elastic pads made of rubber, silicone, or other materials can be provided on the clamping surface of the elastic clamp to increase the fixation of the fiber filament while reducing damage to the clamping position of the fiber filament.

[0023] Reference Figure 4As shown, the cutting assembly 5 further includes a slide plate 51 and a cutting blade 52 slidably connected to the slide plate 51. A sleeve 7 slidably sleeved on the support frame 2 is connected to the second clamping member 4. The slide plate 51 is disposed on the sleeve 7. During the cutting operation, since the cutting assembly 5 is linked with the second clamping member 4 through the sleeve 7, the cutting assembly 5 moves synchronously when the position of the second clamping member 4 is adjusted, ensuring that the cutting blade 52 is always aligned with the cutting position above the second clamping member 4. The cutting blade 52 is operated to slide horizontally along the slide plate 51, and the blade cuts in a direction perpendicular to the fiber filament axis, avoiding the pulling force generated by transverse cutting. After the cutting is completed, the cutting blade 52 is released. Under the elastic action of the spring 11 between the cutting blade 52 and the slide plate 51, the cutting blade 52 returns to the fixed position, preventing the cutting blade 52 from moving randomly.

[0024] The sleeve 7 is threaded with a locking screw 8. When the position of the second clamping member 4 and the cutting component 5 is fixed before cutting, the locking screw 8 is rotated so that one end of the locking screw 8 is in close contact with the support frame 2, thereby fixing the position of the second clamping member 4 and the cutting component 5 and ensuring the consistency of length during batch sampling.

[0025] Reference Figures 1-4 As shown, furthermore, when determining the position of the second clamping member 4, the vertical distance between the first clamping member 3 and the second clamping member 4 is read by observing the scale line 10 set on the support frame 2, and the sliding position of the second clamping member 4 is effectively calibrated to achieve fixed-length cutting of the fiber filament.

[0026] Reference Figure 1 , Figure 2 As shown, a groove 9 is further provided on the base 1, and the support frame 2 is damped and slidably connected to the base 1. After the fiber filament is cut, the support frame 2 can be slid out from the base 1, and then the support frame 2 and the fiber filament can be sent for testing together. The fiber filament is always in a natural hanging state, vertically and coaxially clamped by the first clamping member 3 and the second clamping member 4, which avoids the damage to the fiber filament, especially its three-dimensional crimped structure, caused by handling and placement operations during the traditional sampling and transfer process. This preserves the original shape of the fiber to the greatest extent and ensures that the subsequent test data can truly reflect the fiber performance.
