Description

Technical Field

[0001] This utility model relates to a spinneret cleaning device, belonging to the field of spinneret cleaning technology. Background Technology

[0002] In the spinning industry, the spinneret is the core component determining the quality of fiber formation. Its surface is covered with hundreds to thousands of micron-sized precision channels, directly affecting the uniformity, fineness, and mechanical properties of the spun products. With the widespread application of high-performance fibers in aerospace, biomedicine, and new energy fields, the industry's requirements for the precision and stability of spinning processes are becoming increasingly stringent. During repeated extrusion in high-temperature, high-pressure spinning solutions, polymers or additives can easily remain in the spinneret channels. If not thoroughly removed, this can lead to defects such as broken fibers and irregularly shaped fibers in subsequent spinning processes, and may even cause permanent blockage of the spinneret channels, resulting in the scrapping of high-value spinnerets. Especially in continuous and intelligent spinning production lines, the efficiency and cleanliness of spinneret cleaning directly affect equipment uptime and production costs. Therefore, developing spinneret cleaning devices adapted to the needs of modern spinning processes has become a key link in improving fiber manufacturing levels and ensuring the mass production of high-value-added products. Technological breakthroughs in this area are of significant strategic importance in promoting the textile industry towards high-end and green development.

[0003] Traditional cleaning methods often employ open industrial water tanks, lacking tanks specifically designed for cleaning spinnerets. These open industrial tanks suffer from several technical drawbacks: First, the lack of a dedicated support structure for the mold, with the mold placed directly at the bottom of the tank, limits the water outlet angle at each channel and makes it impossible to visually observe the rinsing effect. Second, movement of the mold can cause scratches due to friction with the metal tank, affecting the stability of subsequent spinning quality. Third, the excessive rigidity of the contact surface between the groove and the mold makes it prone to displacement after positioning under water flow impact, and manual adjustment can easily cause water splashing. Existing technologies urgently need structural innovation to achieve integrated optimization of stable mold positioning, directional high-pressure rinsing, non-destructive contact protection, and visualized cleaning process monitoring. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a spinneret cleaning device.

[0005] The technical solution is as follows:

[0006] A spinneret cleaning device includes a water tank and a water supply device. The water tank is provided with several support plates for supporting the spinneret. Grooves are provided on the inner wall of the water tank on both sides so that the two ends of the support plates can be embedded into the grooves.

[0007] In one embodiment, the support plate has a two-layer structure, with the upper layer being the contact surface and the lower layer being the supporting body. Each of the bottom ends of the support plate is fixedly installed with a sliding plate having a self-locking function.

[0008] In one embodiment, the contact surface is made of an elastic material, which increases the coefficient of friction while supporting the mold without scratching it; preferably, it is made of rubber.

[0009] In one embodiment, the sliding plate is provided with a recessed hole, and a spring and a ball are disposed in the recessed hole. When the support plate is not carrying the spinneret, the ball is partially ejected from the recessed hole under the action of the spring so that the support plate can move horizontally in the water tank. When the support plate is carrying the spinneret, the ball is embedded in the recessed hole under the gravity of the spinneret on the support plate to achieve self-locking.

[0010] In one embodiment, the groove is located at 2 / 3 of the height of the water tank to prevent water from splashing outwards during mold cleaning; the groove has notches at both ends to facilitate the installation and removal of the support plate, further preventing the support plate from falling and damaging the mold during use.

[0011] In one embodiment, the water supply device is a retractable faucet, and the faucet outlet is equipped with a small-diameter connector with a pressurization function.

[0012] In one embodiment, a water outlet is provided at the bottom of the water tank to drain the cleaning fluid and residues in the mold channels.

[0013] In one embodiment, the water tank is also provided with a bottom support component to increase the height of the water tank so that the mold can be manually rinsed at a suitable angle.

[0014] In one embodiment, a strip light for illumination is installed on one side of the water tank to allow for a more direct observation of the water flow from the mold holes during mold cleaning.

[0015] Advantages of this utility model:

[0016] (1) This utility model is designed with double-sided grooves and adjustable support plates, and an external light source is added. To address the problems of unstable mold positioning and limited viewing angle in traditional cleaning processes, a composite frame structure and precision sliding components are designed in synergy. The groove interface enables the support plate to be positioned quickly. During the cleaning process, the mold is placed on the contact surface of the support plate, thus avoiding the mold being placed directly at the bottom of the water tank and blocking the mold outlet, which would prevent effective cleaning. At the same time, combined with the strip light source on one side of the water tank, the water outlet status of the mold hole can be observed more intuitively, significantly improving the controllability of the cleaning process.

[0017] (2) This utility model incorporates a flexible protection and positioning integrated mechanism. The contact surface of the support plate is covered with an elastic material and treated with surface texture, which enhances the friction positioning performance while protecting the mold. The bottom integrates a ball-spring adaptive locking system, which achieves rigid locking through a pressure response mechanism. When the mechanism bears the mold load, it automatically triggers mechanical self-locking, eliminating the risk of scratches during manual adjustment and ensuring the stability of the mold during high-pressure flushing, thus comprehensively improving the reliability of the equipment and the service life of the mold.

[0018] (3) In this utility model, the water outlet structure of the faucet is designed to increase pressure. To address the problem of low efficiency in removing residues from mold micropores caused by insufficient water pressure in traditional cleaning devices, the design is optimized through fluid dynamics. A small-diameter nozzle is used in conjunction with a flow guide cavity to significantly improve the water flow velocity and impact strength, thereby achieving efficient removal of residues from the pores. At the same time, the adjustable support plate optimizes the water injection angle, significantly shortening the cleaning cycle and improving cleanliness. Attached Figure Description

[0023] The following is a detailed description of this utility model.

[0024] Example 1

[0025] See attached document Figure 1 This embodiment provides a spinneret cleaning device, including a water tank 1 and a water supply device. The water tank 1 is provided with a plurality of support plates 4 for supporting the spinneret, and the inner wall of the water tank 1 is provided with grooves 2 on both sides so that the two ends of the support plates 4 can be embedded into the grooves 2.

[0026] See attached document Figure 1 and attached Figure 2 The support plate 4 has a two-layer structure, with the upper layer being the contact surface 6 and the lower layer being the supporting body. Each of the bottom ends of the support plate 4 is fixedly installed with a sliding plate 7 that has a self-locking function. Preferably, the supporting body of the support plate 4 and the water tank itself are made of stainless steel to avoid rusting due to long-term rinsing. The support plate 4 is installed in the grooves 2 on both sides of the water tank 1 by sliding fit.

[0027] See attached document Figure 2 The contact surface 6 is made of elastic material, which increases the coefficient of friction and supports the mold without scratching it. Preferably, it is made of rubber, which has a high coefficient of friction and its high hysteresis characteristics can effectively dissipate vibration energy. The rubber contact surface 6 is installed on one side of the support plate 4 by screw fastening. The sliding plate 7 is installed on both ends of the other side of the support plate 4 by screw fastening.

[0028] Refer to Appendix 2 and Appendix 3 Figure 3 The sliding plate 7 is provided with a recessed hole 9, and a spring 10 and a ball bearing 8 are provided in the recessed hole 9. When the support plate 4 is not supporting the spinneret, the ball bearing 8 is partially ejected from the recessed hole 9 under the action of the spring 10 so that the support plate 4 can move horizontally in the water tank 1. When the support plate 4 is supporting the spinneret, the ball bearing 8 is embedded in the recessed hole 9 under the gravity of the spinneret applied to the support plate 4 to achieve self-locking.

[0029] See attached document Figure 1 The groove 2 is located at 2 / 3 of the height of the water tank 1 to prevent water from splashing outwards during the mold cleaning process; the groove 2 has notches at both ends to facilitate the installation and removal of the support plate.

[0030] The water supply device uses a retractable faucet 3. The outlet of the faucet 3 is equipped with a small-diameter connector to achieve a pressurization effect. The small-diameter connector has threads and is installed at the outlet of the faucet 3 through threaded connection.

[0031] In practical applications, the bottom of the water tank 1 is provided with a water outlet to drain the cleaning fluid and residue in the mold channel; the water tank 1 is also provided with a bottom support component to increase the height of the water tank 1 so that the mold can be rinsed manually at a suitable angle; a strip light 5 for lighting is installed at the middle position above the groove 2 from the top of the water tank, so that the water outlet of the mold hole can be observed more intuitively when cleaning the mold.

[0032] The specific operating steps of this spinneret cleaning device include:

[0033] S1, install the sliding plates 7 at both ends of the support plate 4 by aligning them with the notches at both ends of the grooves 2 on both sides of the water tank 1.

[0034] S2, the installed support plate is slid to the position where the mold needs to be fixed by the ball bearings 8 on the support plate 4;

[0035] S3, place the mold on the rubber contact surface 6 on the support plate 4 to obtain greater friction so that the mold can be fixed in position; the support plate 4 lifts the mold off the bottom of the tank so that its water output can be observed during subsequent rinsing of the mold; the spring 10 inside the sliding plate 7 contracts under the action of the mold's gravity, and the ball 8 contracts into the concave hole 9 for adaptive locking, ensuring the mold is fixed.

[0036] S4, turn on the faucet 3, and use the pressurized water jet from the small-diameter connector on its outlet to rinse the mold surface and channels. At the same time, use the light source of the strip light 5 to help observe the water outlet status of the mold channels. The water flows out through the outlet at the bottom of the water tank 1.

[0037] S5. After the mold cleaning is completed, the permeability of the spinneret can be manually tested directly on the support plate 4 without removing the mold from the water tank for testing.

[0038] S6, after the mold is removed, the support plate 4 loses the weight of the mold, the ball 8 is ejected from the concave hole 9 by the action of the spring 10, the support plate 4 resumes the sliding effect, and the sliding support plate 4 is disassembled at both ends of the groove 2.

[0039] The working principle of this utility model:

[0040] (1) Working principle of groove and adjustable support plate: The groove interface facilitates quick alignment and positioning of the support plate; the ball array at the bottom of the support plate forms a floating support effect under the action of spring preload, and the support plate can slide through the ball when it is not subjected to the gravity of the mold. During the sliding process, the spring group in the sliding plate absorbs vibration energy through elastic deformation, maintaining the smooth movement of the support plate.

[0041] (2) Working principle of the flexible protective positioning mechanism: Integrating the principles of material mechanics and mechanical self-locking, the micro-textured surface of the elastic rubber contact surface of the support plate increases the static friction by increasing the effective contact area. Its viscoelastic properties deform under pressure, wrapping around the edge of the mold and forming a distributed stress buffer. When the mold load reaches the threshold, the support plate sinks, triggering the displacement constraint mechanism of the ball-spring system—spring compression causes the ball to sink into the limiting recess, forming a three-dimensional mechanical limit. At the same time, the wedge-shaped structure inside the recess generates a self-locking effect under pressure. It can absorb the high-frequency vibration of water flow impact and resist lateral shear force, forming multi-dimensional stable protection.

[0042] (3) Working principle of the pressure booster joint structure: This structure realizes energy conversion through the principle of fluid cross-sectional area abrupt change. When water flows through the gradually narrowing small-diameter nozzle, the flow velocity increases significantly as the cross-sectional area decreases. The streamlined contour of the guide cavity further eliminates turbulence and guides the water flow to form a laminar flow state, ultimately concentrating kinetic energy into a high-energy jet. In the directional impact mode, the high-pressure water flow is injected along the axis of the mold channel, using fluid shear force to overcome the adhesion force between the residue and the hole wall. At the same time, with the help of the adjustable support plate angle adjustment function, the jet injection angle is always dynamically matched with the channel tilt direction, ensuring full coverage cleaning of the inner wall of the channel.
