Description

Technical Field

[0001] The invention relates to a clamping device, in particular to a detachable spinneret clamp and an operating method thereof. Background Art

[0002] The spinneret is the core component of the spinning equipment. Its function is to extrude the polymer melt or spinning liquid through the micropores to form fibers. The processing and detection accuracy of the spinneret directly affects the quality and performance of the spinning products. In the fiber production process, the spinneret has a large number of micropores, small pore size and dense distribution, and the micropores are usually required to have extremely high roundness, smoothness and patency. Due to the processing accuracy of the micropores and the complexity of subsequent detection, the clamping and detection methods of the spinneret have become key technical links in the industry. At present, the detection methods of the spinneret are roughly divided into contact and non-contact types. The contact detection method mainly relies on air pressure or hydraulic equipment to determine whether the spinneret is blocked by detecting the air flow or liquid passing through the micropores. This method has a certain adaptability, but due to direct contact with the spinneret surface, it may cause contamination or scratch problems. In addition, the fixture of the contact detection usually adopts a fixed structure, which is only applicable to spinnerets of specific specifications, is difficult to adjust flexibly, and has low operating efficiency.

[0003] Non-contact inspection methods include manual visual inspection and projector inspection. Manual visual inspection uses a microscope to observe the roundness, smoothness and blockage of the micropores. However, this method relies on the experience of workers, has low inspection efficiency and is prone to misjudgment. Projector inspection can achieve multi-hole size measurement, but requires precise clamping of the spinneret. Since the number of micropores on the spinneret usually reaches hundreds to thousands, the design of the existing fixture lacks flexibility, which increases the difficulty of operation and labor intensity, further reducing the inspection efficiency. Most of the spinneret inspection equipment commonly used in the domestic market is imported from Switzerland, Germany and other countries. For example, the equipment of Swiss WETZEL and German ENKA uses contact air pressure and oil pressure detection technology, but the fixture structure design of these devices does not fully consider the diversity and protection needs of the spinneret, which may cause damage to the finished spinneret during the inspection process. Especially in the inspection of high-precision spinnerets, this fixture design that lacks customization and flexibility seriously affects the reliability of the inspection results and the consistency of the product.

[0004] In the prior art, the following problems are common in the fixtures of spinnerets: 1) The non-removability limits the flexibility of operation: Traditional fixtures are mostly fixed structures and cannot be adjusted according to the size, shape or material of the spinneret. For production needs with frequent changes in specifications, the versatility of fixed fixtures is insufficient, resulting in time-consuming replacement of equipment or fixtures, affecting production efficiency. 2) Lack of protection measures for the surface of the spinneret: During the clamping process, since the fixture design does not fully consider the characteristics of the spinneret surface, scratches or deformation may be caused by uneven clamping force, reducing the service life of the spinneret and increasing production costs. 3) Insufficient clamping accuracy: Existing fixtures often rely on manual adjustment for spinneret positioning, making it difficult to achieve high-precision automatic alignment. This is prone to errors for spinneret detection with high micropore precision requirements, affecting the reliability of the detection results. 4) Low operating efficiency: Whether it is contact or non-contact detection, the existing fixtures are cumbersome to operate during installation and adjustment, lack the function of rapid clamping and positioning, resulting in low detection efficiency and difficulty in adapting to the needs of large-scale production environments. Summary of the invention

[0005] The present invention aims to solve the problems of existing spinneret clamps, such as non-removability, inflexible clamping, insufficient positioning accuracy, and poor protection of the spinneret surface, so as to improve the efficiency and reliability of the spinneret detection process. By designing a detachable spinneret clamp, the following objectives are achieved: a spinneret clamp with a detachable structure is provided, which can quickly adapt to spinnerets of different specifications and shapes. The clamp supports rapid replacement and adjustment, meets the needs of frequent replacement of spinnerets in the production line, and significantly improves the versatility and operating efficiency of the equipment. Introducing an elastic cushion layer and a clamping force limiter in the clamp design ensures that the spinneret will not be scratched or deformed during the clamping process due to excessive clamping or uneven contact, thereby extending the service life of the spinneret and reducing the scrap rate of the finished product. By adding positioning grooves and positioning pins, combined with the precise alignment structure of the clamp, the position of the spinneret in the detection equipment is ensured to be accurate. The design can meet the needs of high-precision spinneret detection and improve the consistency and reliability of the detection results. The motor-driven telescopic rod and detachable clamping block are used to automatically clamp and release the spinneret, greatly reducing the complexity and repetitiveness of manual operations. The quick clamping and disassembly function can shorten the test preparation time and improve the overall efficiency of the production line.

[0006] The present invention provides the following technical solutions:

[0007] A detachable spinneret clamp comprises a spinneret, a base and a clamp; the surface of the base is provided with a plurality of positioning grooves for positioning the clamp, and the surface of the base is also provided with a plurality of screw holes for detachable connection with the clamp; at least one group of symmetrical lead screws are installed on the surface of the base, each of which is provided with a sliding block, a telescopic rod driven by a motor is fixed to the side of the sliding block, and a clamping block is detachably installed on the end of the telescopic rod away from the sliding block; positioning holes and positioning pins matching the positioning grooves are provided on the clamp, and the positioning pins are inserted into the positioning grooves after passing through the positioning holes; a first notch for installing the spinneret is provided in the middle of the clamp, and a second notch is symmetrically provided on the side of the clamp, and the telescopic rod is pressed against the side of the spinneret after passing through the corresponding second notch.

[0008] Preferably, at least three groups of positioning grooves are provided on the surface of the base.

[0009] Preferably, a threaded hole is formed on the second notch, and the clamp is detachably fixedly connected by a bolt passing through the threaded hole and a screw hole on the base.

[0010] Preferably, the clamping block is a rubber block, and the curvature of the clamping block matches the curvature of the spinneret.

[0011] Preferably, sliding grooves are provided on the clamps at both sides of the second notch.

[0012] Preferably, an elastic cushion layer is provided in the first notch of the clamp, and the elastic cushion layer is made of silicone or polyurethane.

[0013] Preferably, a limiting device is provided between the telescopic rod and the clamping block, and the limiting device comprises a mechanical limiting piece and a spring.

[0014] Preferably, the detachable spinneret clamp also includes a shock-proof washer, the shock-proof washer or the anti-loosening structure, the shock-proof washer is a spring washer, and the anti-loosening structure is an anti-loosening nut; the shock-proof washer is installed between the bolt and the threaded hole, and the anti-loosening structure is installed on the telescopic rod to prevent the telescopic rod from moving relative to the sliding block.

[0015] The present invention also provides an operating method of the above-mentioned detachable spinneret fixture, comprising the following steps:

[0016] Pass at least two positioning pins through the positioning holes and insert them into the positioning grooves to realize the positioning of the clamp on the base, and then pass the bolts through the threaded holes and detachably and fixedly connect them with the screw holes;

[0017] Place the spinneret in the first notch, move the sliding block on the symmetrical lead screw to the predetermined position and lock it, then use the motor to drive the telescopic rod to extend so that the clamping block passes through the second notch and rests against the spinneret to clamp the spinneret.

[0018] The beneficial effects of the present invention are:

[0019] 1) Existing spinneret clamps mostly adopt a fixed design, lacking flexible adjustment capabilities and difficult to meet the needs of spinnerets of different specifications. The present invention designs multiple groups of positioning grooves and screw holes, and combines the use of positioning pins, so that the clamp can be quickly adjusted between different spinneret specifications, greatly improving the versatility of the equipment and the convenience of operation. Automatic clamping can be achieved through the telescopic rod and clamping block driven by the motor, avoiding the cumbersome steps of traditional manual adjustment and saving a lot of operation time. This design is particularly suitable for production lines that need to frequently replace spinnerets. It can complete the adjustment of the clamp and the clamping of the spinneret in a shorter time, greatly improving the overall efficiency of the production line. Compared with traditional manual clamps and fixed clamps, the automatic clamping device reduces manual intervention, reduces the labor intensity of operators, and reduces the risk of uneven clamping or spinneret damage caused by improper manual adjustment. The motor drive system makes the spinneret clamping process more accurate and efficient, greatly improving the automation level of the equipment.

[0020] 2) Enhance the surface protection of the spinneret and extend the service life: The spinneret has very high precision requirements during the spinning process, especially the quality and surface finish of the micropores. Any improper clamping may damage the surface of the spinneret, resulting in a decrease in product quality or damage to the spinneret. Traditional clamps often lack appropriate surface protection design, and uneven pressure is easily generated during the clamping process, causing scratches or deformation of the spinneret. However, the present invention uses a clamping block made of rubber material and customizes it according to the curvature of the spinneret, so that the clamping block is more in line with the surface of the spinneret, effectively dispersing the clamping force, and avoiding damage to the surface of the spinneret caused by excessive or uneven clamping of the traditional clamp. In addition, the present invention designs an elastic cushion layer in the first notch of the clamp, using materials such as silicone or polyurethane, which can not only further improve the contact flexibility between the clamp and the spinneret, but also absorb part of the impact force generated during clamping, further reducing damage to the spinneret. Such a design significantly improves the protection of the spinneret, extends its service life, reduces the scrap rate caused by surface damage, and thus reduces production costs. Improve the positioning accuracy and clamping stability of the spinneret: The precise clamping of the spinneret is crucial to the stability of the spinning process, especially in high-precision detection or precision machining processes, where a slight deviation in the position of the spinneret may lead to process failure or product quality problems. Traditional fixtures often rely on manual adjustment, making it difficult to ensure the accuracy of clamping. In contrast, the fixture of the present invention can ensure the accurate position of the spinneret in the fixture through a precisely designed positioning groove and positioning pin system, thereby avoiding quality fluctuations caused by inaccurate positioning. Through the cooperation of the positioning pins, the fixture can be stably fixed on the base to ensure that the position of the spinneret does not change during processing or testing. This precise positioning system not only ensures the clamping accuracy of the spinneret, but also provides a stable foundation for subsequent processing and testing, especially in the spinneret micropore detection process, which can ensure that the detection data of each micropore has a high degree of consistency and accuracy.

[0021] 3) Adapt to the diversified needs of spinnerets of different specifications and materials: There are many types of spinnerets, and the sizes and materials vary greatly. Traditional fixtures can often only adapt to spinnerets of a certain specification, which makes it difficult for the equipment to operate efficiently in a multi-variety production environment. The fixture of the present invention can be flexibly adjusted according to the different specifications and materials of the spinneret through a detachable design, and can adapt to many different types of spinnerets. The multiple groups of positioning grooves and adjustable fixture designs set on the base enable the same fixture to be used for spinnerets of different sizes, shapes and even different materials, greatly improving the adaptability and versatility of the equipment. This design not only improves the flexibility of the production line, allowing the equipment to quickly adapt to changes in production needs, but also reduces the time cost of replacing or adjusting the fixture of the equipment, and improves the overall production efficiency of the production line. Whether in mass production or small batch customized production, the fixture design can meet the efficient clamping requirements of spinnerets of different specifications. Improve the automation level of the production line. The present invention uses a telescopic rod driven by a motor and a quick-adjusting fixture design, so that the clamping and disassembly process of the spinneret can be completed automatically, reducing the complexity of manual operation. The traditional manual clamping system is not only time-consuming but also prone to uneven clamping and even damage to the spinneret due to improper human operation. Through automated design, the production line can achieve a higher level of automation, reduce manual intervention, and improve production stability and precision. The automated clamping system can quickly adapt to the production rhythm, reduce downtime caused by improper clamp adjustment, and improve overall production efficiency. Especially in the continuous production process, the automatic clamping system can continuously maintain an efficient production state, avoiding production interruptions and inefficiencies caused by manual operation.

[0030] Embodiment 1

[0031] The detachable spinneret fixture described in this embodiment is composed of multiple key components, which ensure that the spinneret can be stably and accurately fixed during use through precise design and structural combination, while avoiding damage to the spinneret surface. Figure 1 As shown, the whole device includes a base 2, a clamp 3, a lead screw 201, a sliding block 202, a telescopic rod 203 driven by a motor, a clamping block 204, a positioning pin 305 and an elastic cushion layer. The following is a detailed description of each component. Figure 2 As shown, the base 2 serves as a supporting platform for the entire clamp device and provides a stable installation foundation. The surface of the base is provided with a plurality of positioning grooves 205 and screw holes 206. The positioning grooves 205 are used for the precise positioning of the clamp to ensure that the clamp is stable and does not shift after installation. The screw hole 206 is designed to ensure that the clamp can be firmly connected to the base, so that the clamp system can withstand high-intensity workloads, while ensuring that the spinneret will not loosen or deviate from its position during the clamping process. The design of the base not only supports the stable operation of the equipment, but also has good adaptability to accommodate spinnerets of different specifications. Figure 3As shown, the clamp 3 is the main component for clamping the spinneret, and its structural design is closely matched with the base. The surface of the clamp is provided with a plurality of positioning holes, which are precisely docked with the positioning groove 205 on the base to ensure that the clamp can be stably fixed on the base, thereby avoiding displacement of the clamp during the clamping process. The middle part of the clamp is designed with a notch 304 for accommodating the spinneret, and the spinneret can be accurately placed through the notch to ensure stability during the clamping process. The side of the clamp is also designed with a plurality of adjustable second notches 301, through which the telescopic rod 203 can accurately pass through and be fixedly connected with the clamp, thereby achieving precise clamping. The design of the lead screw 201 and the sliding block 202 provides the function of precise adjustment. The lead screw 201 is mounted on the surface of the base, and the sliding block 202 is fixed on the lead screw and can slide smoothly along the lead screw. By adjusting the position of the sliding block 202, the clamping position of the clamping block 204 can be controlled, thereby ensuring the precise clamping of the spinneret. The detachable spinneret clamp also includes an anti-vibration washer, the anti-vibration washer or anti-loosening structure, the anti-vibration washer is a spring washer, and the anti-loosening structure is an anti-loosening nut; the anti-vibration washer is installed between the bolt 303 and the threaded hole 302, and the anti-loosening structure is installed on the telescopic rod 203 to prevent the telescopic rod 203 from moving relative to the sliding block 202. The telescopic rod 203 driven by the motor is connected to the sliding block, and the other end of the telescopic rod is connected to the clamping block 204. When the motor is started, the telescopic rod drives the clamping block to move up and down in the clamp, and the automatic clamping of the spinneret is achieved in this way. The clamping block 204 is a component that directly contacts the spinneret, and its design is crucial. The clamping block uses a flexible material, such as rubber or other elastic materials, to ensure that no excessive pressure is generated on the spinneret during the clamping process, and to avoid scratches or deformation of the spinneret surface due to excessive clamping. The shape of the clamping block matches the curvature of the spinneret to maximize the uniformity and stability of the clamping effect, thereby protecting the spinneret from damage during the clamping process. In order to ensure the accurate positioning of the fixture, the positioning pin 305 plays a key role between the fixture and the base. The positioning pin 305 is inserted into the positioning groove 205 through the positioning hole, so that the fixture can be stably fixed on the base, avoiding the problem of uneven clamping caused by improper installation. This design effectively improves the stability of the fixture system and ensures that the position of the spinneret in the fixture will not change.

[0032] In addition, the fixture design also takes into account the adaptability of spinnerets of different specifications. The multiple positioning grooves and adjustable fixture design on the base enable the same fixture to adapt to spinnerets of different sizes, shapes and even different materials. This flexible design not only improves the versatility of the production line, but also can be quickly adjusted according to actual needs to adapt to different process requirements and spinneret specifications. This embodiment also specially designs a limiter to control the clamping force to prevent excessive or uneven clamping. The limiter includes a mechanical limiter and a spring structure to ensure that the maximum clamping force of the clamping block is within a safe range, thereby protecting the spinneret from damage. The limiter plays a vital role in the clamping process, and can effectively prevent the fixture from applying excessive force during the clamping process and protect the integrity of the spinneret. In addition, the design of the elastic cushion layer makes the contact between the fixture and the spinneret softer. The elastic cushion layer is usually made of materials such as silicone or polyurethane, which can effectively absorb the impact force during the clamping process and reduce the wear on the surface of the spinneret. This design further improves the protection of the spinneret, ensuring that the spinneret will not be scratched or deformed due to the clamping of the fixture during multiple uses. Finally, the detachable design enables the fixture to be quickly replaced or adjusted when needed. Traditional fixtures can usually only adapt to spinnerets of specific specifications, while the fixture design of the present invention can quickly adjust or replace the fixture components according to the needs of spinnerets of different specifications, thereby improving the flexibility and efficiency of the production line. Through this detachable design, the maintenance and operation of the production line also become more convenient, reducing downtime and improving production efficiency. In summary, the detachable spinneret fixture of this embodiment significantly improves the clamping accuracy of the spinneret and the work efficiency of the production line through a precise positioning system, an automated clamping device, flexible protection measures and a flexible adaptation design. The multifunctional design of the fixture not only enables the equipment to adapt to spinnerets of different specifications and materials, but also improves the versatility and stability of the fixture system, ensuring the safety and efficiency of the spinneret during processing and testing.

[0033] Embodiment 2

[0034] The detachable spinneret fixture described in this embodiment includes multiple key components, which are precisely designed and structurally combined to ensure the efficiency, accuracy and protection of the spinneret during the clamping, testing and processing. First, the base 2 serves as the support platform for the entire device, with a diameter of 300mm and a thickness of 15mm. Four positioning grooves 205 are provided on the surface of the base, each of which is 50mm long, 5mm wide and 3mm deep, for precise positioning of the fixture to ensure that the fixture is stable and does not shift during use. Figure 5As shown, the base is also equipped with six screw holes 206 with a diameter of 6mm and a depth of 12mm, which are used to firmly fix the clamp to the base. The base is made of aluminum alloy material, which has high strength and corrosion resistance and can adapt to long-term high-load working requirements. The clamp 3 is responsible for accurately fixing the spinneret. Its dimensions are 150mm long, 100mm wide and 20mm thick. It is made of high-strength steel and the surface is treated with anti-corrosion to ensure its durability and stability in long-term use. A first notch 304 is designed in the middle of the clamp. The notch size is 140mm×80mm, which is used to accurately accommodate the spinneret. As shown in FIG. Figure 4As shown, two second notches 301 are provided on both sides of the clamp, each of which has a width of 15 mm and a height of 8 mm, for the installation and adjustment of the telescopic rod. Through these notches, the telescopic rod can be accurately moved and fixed on the clamp to ensure the stability of the spinneret when clamped. The design of the lead screw 201 and the sliding block 202 provides a precise adjustment function. The lead screw 201 has a length of 250 mm and a diameter of 12 mm. The material is high-strength stainless steel and is installed on the surface of the base. The sliding block 202 is fixed on the lead screw, and the size of the sliding block is 20 mm x 30 mm, allowing it to slide smoothly along the lead screw. By adjusting the position of the sliding block, the position of the clamping block is controlled, thereby achieving precise spinneret clamping. The motor-driven telescopic rod 203 is fixed on the side of the sliding block, and the other end of the telescopic rod is connected to the clamping block 204. The length of the telescopic rod 203 is 150 mm, and it can be driven by the motor to move up and down in the clamp to ensure automatic clamping of the spinneret. The clamping block 204 is made of a flexible material such as rubber, which can ensure that no excessive pressure is applied to the spinneret during the clamping process, thereby avoiding damage or deformation of the spinneret surface. The shape of the clamping block 204 matches the curvature of the spinneret to ensure that the clamping effect is uniform and stable. The positioning pin 305 plays a key role in the positioning of the entire fixture. The positioning pin 305 cooperates with the positioning groove 205 through the positioning hole, so that the fixture can be accurately fixed on the base. The diameter of the positioning pin is 5mm and the length is 20mm, which ensures that the fixture can be stable and not shifted, thereby avoiding the uneven clamping caused by improper installation. This embodiment also includes a limiting device for ensuring the control of the clamping force. The limiting device is composed of a mechanical limiting plate and a spring structure, which can prevent excessive clamping and protect the spinneret from damage. The limiting device plays a vital role in the clamping process, ensuring that the clamping force of the spinneret in the fixture is within a safe range. In addition, an elastic cushion layer is added to the clamp design, using materials such as silicone or polyurethane. The thickness of the elastic cushion layer is 5mm, which can absorb impact force during the clamping process, reduce wear on the surface of the spinneret, further improve the protection of the spinneret, and ensure that the spinneret is not scratched or deformed during long-term use. Finally, the detachable design of this embodiment allows the clamp to be quickly adjusted and replaced to adapt to spinnerets of different specifications and materials. The multiple positioning grooves and adjustable clamp design on the surface of the base allow the same clamp to adapt to spinnerets of different sizes, shapes and even different materials, enhancing the flexibility and versatility of the device. This design not only improves the versatility of the production line, but also allows the clamp to be quickly adjusted according to production needs, reducing downtime and improving production efficiency.
