Description

Technical Field

[0001] This utility model belongs to the field of spinning equipment technology, specifically relating to a raw yarn frame for a texturing machine. Background Technology

[0002] In the polyester filament industry, DTY bobbins are continuously produced by texturing machines using POY (pre-oriented yarn) raw materials. To ensure a high degree of production continuity, a knotting process is required to connect the spare raw materials with the raw materials currently in use, thereby achieving a smooth transition when the raw materials are spun to the bottom of the bobbin. Otherwise, yarn breakage will lead to the need for re-spinning. Therefore, the success rate of the yarn finish is crucial to ensuring production efficiency, and the daily management of POY raw materials is the core of ensuring the success rate of the yarn finish.

[0003] In existing technologies, most yarn trays are equipped with pressure plates on the yarn tray baffle to hold down the knotted yarn, preventing it from drifting and thus improving the success rate of yarn finishing. However, with the increasing market demand for high-end DTY products such as porous yarns and ultra-fine denier yarns, the ability of traditional hardware to ensure the success rate of yarn finishing is insufficient. For example, patent CN220887840U discloses a texturing machine yarn tray with an added movable pressure plate. This texturing machine yarn tray has one pressure plate body on each yarn tray partition, which presses down under the raw material being produced after finishing to prevent external force from entanglement and entanglement during yarn finishing. This technology can effectively fix conventional POY yarns and ensure the stability of the yarn at the end. However, in the production of ultra-fine denier and porous yarns, the success rate of yarn finishing with this structure is not good, mainly due to the following drawbacks:

[0004] Problem of tangled waste wire: After prolonged use, waste wire will gradually become entangled on the spacers of the pressing sheet, and the waste wire will be entangled very tightly. When dealing with the tail wire, if the individual wires have poor cohesion and come apart, or if improper operation leads to poor trimming (such as excessively long knot ends, loose original wire connection sections, and insufficient knot strength), waste wire is more likely to become entangled, thus causing the problem of broken ends and resulting in a poor success rate of finishing the tail wire.

[0005] The compressive force exacerbates the breakage: The static compressive force applied by the upper pressure plate is superimposed with the dynamic over-tangle force, making the entanglement between the monofilament and the waste filament more tight. This not only leads to the breakage and poor over-tangle success rate, but also damages the monofilament.

[0006] High cleaning difficulty: The small size of the pressure plate makes it very difficult to clean the waste yarn wrapped around the spacer ring. Even with a sharp knotting knife, it is difficult to reach into the tightly wrapped waste yarn loops. Daily cleaning is difficult to implement comprehensively, affecting the success rate of finishing. Regularly disassembling the pressure plate to clean the waste yarn is not only time-consuming and laborious, but also causes random breakage or single-filament damage during production due to the varying degrees of waste yarn wrapping.

[0007] The aforementioned drawbacks have severely impacted production efficiency, economic benefits, and product quality. Therefore, in order to meet the production demands of high-end products such as ultra-fine denier filaments and porous filaments, it is urgent to improve existing technologies to address these shortcomings. Utility Model Content

[0008] The purpose of this invention is to solve the problems existing in the prior art and to provide a raw yarn frame for a texturing machine.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A raw yarn frame for a texturing machine includes a raw yarn frame body and a yarn frame baffle horizontally arranged inside the raw yarn frame body. The upper surface of the yarn frame baffle is provided with n flow guiding devices, n≥1. Each flow guiding device is connected to a branch pipe below, and the branch pipe is connected to a suction device.

[0011] The guiding device is equipped with several micro-holes that are evenly distributed. These micro-holes can easily capture the knotted yarn. Simply bring the yarn close to the micro-hole area, and the yarn to be passed through will be in an adsorbed and fixed state (due to the uniform force and the low coefficient of friction of the ceramic part, the yarn is in good condition and there will be no damage). It can only be detached from the boat-shaped ceramic part by tension when the yarn cake is switched to pass through the knot, and thus pass through the knot smoothly.

[0012] As a preferred technical solution:

[0013] As described above, a type of texturing machine uses a raw yarn frame, and the flow guiding device includes a ceramic component, a ceramic component fixing base, and an interface;

[0014] The ceramic pieces are arranged horizontally above the ceramic piece fixing base. The upper surface of the ceramic pieces is provided with grooves, and micropores are evenly distributed at the bottom of the grooves.

[0015] The interior of the porcelain piece has a cavity with a crescent-shaped vertical cross-section. The top of the cavity is the bottom of the groove, and the crescent-shaped cavity can provide a relatively uniform suction force to the micropores at the bottom of the groove.

[0016] One end of the interface is connected to the bottom of the ceramic fixture and communicates with the cavity, while the other end is connected to the branch pipe.

[0017] As described above, a texturing machine uses a raw yarn frame where n is 1.

[0018] The raw yarn frame for a texturing machine, as described above, has 13 micropores.

[0019] As described above, the micropores in the texturing machine have a diameter of 0.3-1.5mm. This size of micropore is suitable, and the yarn will not be sucked into the cavity.

[0020] As described above, a raw yarn frame for a texturing machine has a total of m layers from top to bottom, with k yarn frame baffles on each layer, where m≥2 and k≥1; the flow guiding devices on the same layer are all connected to the same branch pipe, and the branch pipes on different layers are all connected to the same main pipe, which is connected to a suction device.

[0021] As described above, the raw yarn frame for a texturing machine uses a variable frequency vacuum pump as the suction device.

[0022] Beneficial effects:

[0023] This invention employs an innovative adsorption and fixation method, which, compared to the traditional method of pressing the filaments with a pressure plate, has the following significant advantages:

[0024] Adsorption fixation reduces filament damage: During filament adsorption and over-knotting, the frictional resistance of the filament detaching from the ceramic surface is much less than that of traditional metal pressure plates. This completely avoids the problem of filament entanglement caused by traditional pressure plates pressing down on the filament, greatly reducing the probability of single filament damage due to friction, and effectively ensuring filament quality and over-knotting success rate.

[0025] Simplified operation and improved efficiency: The new adsorption and fixation method eliminates the need for operators to lift the upper pressure plate and manually press down the filaments; the filaments can be easily adsorbed as soon as they are brought close. The honeycomb-type filament suction groove is designed in a semi-open state, making the condition of the ceramic parts clear at a glance. During normal non-knotting periods, operators can directly observe and clean the ceramic parts without relying on maintenance personnel, and there is no need to laboriously deal with tangled waste filaments. This design reduces the frequency of maintenance, greatly improves the efficiency of operation, and ensures that the success rate of knotting each batch of raw filaments can be maximized.

[0026] Intelligent adjustment with strong adaptability: Equipped with a variable frequency vacuum pump drive motor with variable frequency speed regulation, the negative pressure value can be flexibly adjusted according to different specifications of yarn. The number and position of the honeycomb suction slots can be flexibly set according to specific needs, so as to more accurately deal with the difference in tail yarn quality and better adapt to the tail yarn requirements of different specifications of yarn.
