Description

Technical Field

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

[0002] In the quality inspection process of cotton spinning enterprises and chemical fiber production enterprises, quality supervision and management agencies, yarn and chemical fiber testing instruments need to be equipped with automatic yarn feeding, clamping, and drawing devices to achieve automated batch testing and improve production inspection efficiency.

[0003] Currently, the feeding, clamping, and drawing devices of yarn and chemical fiber testing instruments have complex structures, requiring multiple motion drive components to work together, and the structural design and electrical control design must be coordinated. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide a textile fiber feeding detection device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A textile fiber feeding detection device includes a force measuring mechanism, with a yarn feeding cylinder at the inlet of the force measuring mechanism and a yarn suction tube at the outlet of the force measuring mechanism, the outlet of the yarn suction tube being connected to a collecting mechanism.

[0007] The output end of the yarn bobbin is provided with a guide mechanism, through which the yarn passes into the force measuring mechanism.

[0008] The guiding mechanism is a positive yarn loop, which changes the yarn path or direction so that the originally inclined yarn is aligned with the effective clamping area of ​​the force measuring mechanism.

[0009] The yarn suction tube is fixedly equipped with a yarn clamping mechanism and a push-pull mechanism. One end of the push-pull mechanism is connected to the yarn clamping mechanism, and the push-pull mechanism drives the yarn clamping mechanism to move together when it moves.

[0010] The collection mechanism includes a negative pressure generating mechanism connected to the outlet of the yarn suction tube.

[0011] The output end of the negative pressure generating mechanism is connected to a waste filament collection box.

[0012] The yarn suction tube is connected to the negative pressure generating mechanism via a pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention provides a textile fiber feeding and detection device. It uses a suction tube to rotate the yarn bobbin, continuously supplying yarn. The suction tube is connected to a negative pressure mechanism via a pipe, which uses the negative pressure generated by the mechanism to draw in the yarn. This device significantly reduces the mechanical movement of its components. Compared to existing technologies, it eliminates the need for motors, worm gear reducers, linear guides / guide rods, sprockets, and chains, thereby improving detection efficiency, reducing the failure rate of moving parts, lowering production costs, and enhancing maintenance convenience. Furthermore, it automates the yarn picking, feeding, clamping, and testing processes, reducing manual labor and the workload of testing personnel, and improving test consistency.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0018] like Figure 1 As shown, this utility model provides a textile fiber feeding and detection device, including a force measuring mechanism 3. A yarn feeding cylinder 1 is provided at the inlet of the force measuring mechanism 3, and a yarn suction tube 4 is provided at the outlet of the force measuring mechanism 3. The outlet of the yarn suction tube 4 is connected to a collection mechanism, which can complete the yarn feeding, yarn clamping and yarn pulling process during yarn detection.

[0019] Preferably, the output end of the yarn bobbin 1 is provided with a guiding mechanism, through which the yarn 10 of the yarn bobbin 1 passes into the force measuring mechanism 3. For example, the guiding mechanism is a positive yarn loop 2, which changes the path or direction of the yarn, so that the originally inclined yarn is aligned with the effective clamping area of ​​the force measuring mechanism 3. The force measuring mechanism 3 mainly detects the yarn through a force sensor. By adjusting the position and angle of the positive yarn loop 2, the inclination of the yarn can be changed, thus adjusting the position of the yarn entering the force measuring mechanism 3. The yarn 10 is either yarn or synthetic fiber.

[0020] The yarn suction tube 4 is fixedly equipped with a yarn clamping mechanism 5 and a push-pull mechanism 6. One end of the push-pull mechanism 6 is connected to the yarn clamping mechanism 5. When the push-pull mechanism 6 moves, it drives the yarn clamping mechanism 5 to move together.

[0021] Additionally, the collection mechanism includes a negative pressure generating mechanism 8 connected to the outlet of the yarn suction tube 4, and the output end of the negative pressure generating mechanism 8 is connected to a waste yarn collection box 9. The yarn suction tube 4 is connected to the negative pressure generating mechanism 8 via a pipe 7.

[0022] The relative positions of the yarn bobbin 1, the positive yarn ring 2, the force measuring mechanism 3, and the yarn suction tube 4 are fixed. The force measuring mechanism 3 is located at the rear of the positive yarn ring 2. The yarn suction tube 4 is connected to the negative pressure mechanism 8 through the pipe 7, and the yarn suction tube 4 uses the negative pressure generated by the negative pressure mechanism 8 to draw in the yarn.

[0023] The working principle and process of this utility model:

[0024] A pushing and pulling mechanism 6 is fixed inside the yarn suction tube 4. The pushing and pulling mechanism 6 is connected to the yarn clamping mechanism 5. When the pushing and pulling mechanism 6 moves in a telescopic motion, it drives the yarn clamping mechanism 5 to move together. When the yarn clamping mechanism 5 moves to the appropriate position of the yarn suction tube 4, it clamps the yarn, stopping the rotation of the yarn bobbin. The force measuring mechanism 3 clamps the yarn, and after the yarn clamping mechanism 5 moves in the opposite direction for an appropriate distance to tension the yarn, it begins to move downward. The force measuring mechanism 3 detects the change in the yarn. After the test is completed, the negative pressure generates the force measuring mechanism 3 to clamp the yarn, sucking away the waste yarn and discharging it into the waste yarn collection box.

[0025] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
