Description

Technical Field

[0001] This application relates to the technical field of producing spinneret filter screens, and in particular to a spinneret filter screen leveling device. Background Technology

[0002] In chemical fiber production, the spinneret filter is a critical component, and its quality directly affects the quality of the chemical fiber products. Spinneret filter blanks are typically manufactured using a deep-drawing process. However, during manufacturing, due to deformation stress, the bottom surface of the spinneret filter may bulge after the initial punching process. This deformation severely impacts subsequent processing steps, such as the punching process, leading to issues like punching position deviations and irregular hole shapes. This, in turn, reduces the filter's filtration performance and ultimately affects the quality of the chemical fiber products.

[0003] Currently, the common shaping method used in the industry is for workers to use bakelite punches to hold the deformed parts and then flatten them by tapping. Because this method is manual, it is difficult to ensure that the force and position of flattening are completely consistent each time, resulting in poor flattening effect, inconsistent product quality, and low efficiency of manual operation, which is difficult to meet the needs of large-scale production. In addition, frequent tapping operations can easily damage the spinneret filter screen, further reducing the pass rate of spinneret filter screen production.

[0004] Regarding the aforementioned technologies, the inventors believe that there are drawbacks, such as operators using bakelite punches to press against deformed parts and then smoothing out the deformed and bulging spinneret filter by tapping, resulting in poor consistency in smoothing effect and low operational efficiency. Utility Model Content

[0005] To address the issues of inconsistent leveling results and low operational efficiency caused by operators using bakelite punches to press against deformed areas and then striking to level the bulging spinneret filter, this application provides a spinneret filter leveling device.

[0006] This application provides a spinneret filter screen leveling device, which adopts the following technical solution:

[0007] A spinneret filter screen leveling device includes a support base, a positioning seat installed at the bottom of the support base, a positioning hole for placing the spinneret filter screen on the positioning seat, a bracket provided at the top of the support base, an operating rod rotatably mounted on the bracket, a pressure rod slidably mounted on the operating rod, and the other end of the pressure rod passing through one end of the support base and cooperating with the spinneret filter screen to press down and level the spinneret filter screen.

[0008] By adopting the above technical solution, the support base provides a stable support foundation for the entire device, the positioning base uses positioning holes to achieve precise positioning of the spinneret filter screen, ensuring that the placement position is consistent each time, the bracket provides a rotation fulcrum for the operating rod, the operating rod drives the pressure rod to move, so that the pressure rod can accurately apply pressure to the deformed parts of the spinneret filter screen for leveling, realizing efficient and precise leveling operation of the spinneret filter screen, which greatly improves the efficiency and quality of leveling compared with the traditional manual leveling method.

[0009] Optionally, the support base includes a base plate, support columns, and a mounting plate. The support columns are installed at both ends of the base plate, and the support columns are installed between the base plate and the mounting plate. The positioning seat is installed on the base plate, and the bracket is installed on the mounting plate.

[0010] By adopting the above technical solution, the base plate distributes the weight of the device, ensuring that the device is placed stably. At the same time, it provides an installation foundation for the positioning seat. The support column connects the base plate and the mounting plate, maintaining the stability of the vertical structure. Furthermore, the height of the support column can be adjusted to make the operation more comfortable for the operator. The mounting plate provides a stable installation platform for the bracket, enhances the structural strength of the device, and ensures the stable movement of the operating rod and pressure rod, thereby improving the stability and reliability of the leveling operation.

[0011] Optionally, the base plate has a first storage slot and a second storage slot communicating with the first storage slot. A pad is installed in the first storage slot, and the positioning seat is installed in the second storage slot. The end of the pad extends into the positioning hole, and the spinneret filter is disposed above the pad.

[0012] By adopting the above technical solution, the first placement slot precisely positions the pad, the second placement slot securely installs the positioning seat, and the pad provides bottom support for the spinneret filter and extends into the positioning hole for further precise positioning. The three work together to ensure the accuracy and stability of the spinneret filter placement, improve positioning accuracy, and make the position deviation of the spinneret filter smaller during each leveling operation, effectively improving the consistency of the leveling effect.

[0013] Optionally, a base is installed on one side of the mounting plate near the base plate, and the bracket is provided on the other side. A cavity is provided in the base, and a spring is installed in the cavity. The pressure rod passes through the mounting plate and the base in sequence, and the spring is sleeved on the outside of the pressure rod.

[0014] By adopting the above technical solution, the base provides a stable installation space for the spring, ensuring that the spring is fixed in position during operation. The spring stores elastic potential energy when the pressure rod is pressed down. After the pressing operation is completed, the spring releases the elastic potential energy to push the pressure rod to automatically reset, realizing the automatic rise of the pressure rod. This makes it convenient for operators to pick up and put down the spinneret filter screen, improving operating efficiency. At the same time, the spring can also play a buffering role during the pressing of the pressure rod, avoiding excessive impact force from the pressure rod on the spinneret filter screen and protecting the spinneret filter screen from damage.

[0015] Optionally, a limiting element is provided on the pressure rod, and the spring is located between the bottom of the base and the limiting element.

[0016] By adopting the above technical solution, the limiting component restricts the compression degree of the spring and precisely controls the pressing position of the pressure rod, ensuring that the pressure rod can reach the set working position during each pressing operation without excessive pressing. This avoids damage to the spinneret filter screen and ensures that the pressure and effect applied in each leveling operation are basically the same, thus improving the stability of the leveling quality.

[0017] Optionally, the operating lever is provided with a sliding groove, a sliding rod is slidably disposed in the sliding groove, a sleeve rod is sleeved on the sliding rod, and the sleeve rod is coaxially connected to the pressure rod.

[0018] By adopting the above technical solution, the sliding groove provides a specific sliding track for the sliding rod, restricting the movement direction of the sliding rod. As an intermediate component connecting the operating rod, sleeve rod, and pressure rod, the sliding rod combines the rotational movement of the operating rod with the position adjustment of the pressure rod. The sleeve rod plays the role of transmitting force and stabilizing the structure. It smoothly transmits the movement of the sliding rod to the pressure rod, ensuring that the pressure rod can move synchronously with the movement of the sliding rod, thus ensuring the smoothness and accuracy of the pressure rod's movement.

[0019] Optionally, a limiting seat is installed on the top of the support base, and a groove is formed on the limiting seat. The pressure rod is located in the groove, the width of the groove is greater than the diameter of the pressure rod, and the width of the groove is less than the diameter of the sleeve rod.

[0020] By adopting the above technical solution, the groove plays a limiting and guiding role for the pressure rod, ensuring that the pressure rod maintains a stable trajectory during movement and avoiding swaying or deviation of the pressure rod. The sleeve rod cooperates with the edge of the groove to further enhance the restriction on the lateral and longitudinal displacement of the pressure rod, enabling the pressure rod to perform a vertical leveling operation on the spinneret filter screen, improving the accuracy of the pressure rod pressing down, thereby improving the leveling effect and product quality.

[0021] Optionally, the end of the operating lever is provided with a handle ball.

[0022] By adopting the above technical solution, the ball handle increases the contact area between the operator's hand and the control lever, improves grip comfort, reduces hand pressure during long-term operation, and makes it easier for the operator to apply force to rotate the control lever, making operation more convenient and effortless, and improving the operating experience and efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The positioning holes of the positioning seat in this device accurately position the spinneret filter screen, ensuring that the position is fixed each time. The operator can drive the pressure rod to level the spinneret filter screen by rotating the operating rod. Compared with manual leveling by tapping it repeatedly, the operation process is simplified and the time is shortened. It can apply more uniform and stable pressure to the deformed parts of the filter screen, effectively reducing the problem of inconsistent leveling effect caused by differences in the force and position of human operation, greatly improving the leveling accuracy and consistency, and thus improving the stability of product quality.

[0025] 2. The spring reset structure, limiting components, and limiting seat groove in this device ensure the stability of the pressure rod movement and the accuracy of the pressing position, avoid damage to the spinneret filter screen, extend the service life of the device, and enhance the reliability and stability of the device.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a spinneret filter screen leveling device, referring to... Figure 1 and Figure 2 The spinneret filter screen leveling device includes a support base 1, a positioning seat 17 installed at the bottom of the support base 1, a positioning hole for placing the spinneret filter screen 5 on the positioning seat 17, a bracket 2 on the top of the support base 1, an operating rod 3 rotatably mounted on the bracket 2, a pressure rod 4 slidably mounted on the operating rod 3, the other end of the pressure rod 4 passes through one end of the support base 1 and is connected to the spinneret filter screen 5 to press down and level the spinneret filter screen 5.

[0036] In this spinneret filter leveling device, the support base 1 serves as the basic support structure of the entire device, playing the role of bearing and fixing other components. The support base 1 connects the positioning base 17, bracket 2 and other components into a whole, ensuring the stability of the relative positional relationship between the components, providing a stable support platform for the normal operation of the device, and helping to improve the leveling effect and product quality.

[0037] The positioning holes on the positioning seat 17 are used to place the spinneret filter 5. By using positioning holes that match the shape of the spinneret filter 5, precise positioning of the spinneret filter 5 is achieved, ensuring consistent placement each time. During the leveling process, the positioning seat 17 ensures that the spinneret filter 5 is accurately positioned directly below the pressure rod 4, avoiding poor leveling results due to positional deviations, improving the accuracy and consistency of leveling, and also providing an accurate reference for subsequent processes such as punching.

[0038] The bracket 2 is used to rotatably set the operating lever 3, providing support and a fulcrum for the lever 3 to rotate, thereby controlling the pressure lever 4. The well-designed bracket 2 ensures the flexibility and stability of the operating lever 3's rotation, allowing operators to easily drive the pressure lever 4 downwards via the lever 3, making the leveling operation more convenient and efficient.

[0039] The operator rotates the operating lever 3 to move the pressure lever 4. The operating lever 3 serves as a medium for the operator to apply external force, transmitting the operator's force to the pressure lever 4, thereby achieving the downward pressing and leveling operation of the spinneret filter screen 5. In addition, the pressure lever 4 is slidably mounted on the operating lever 3, allowing the pressure lever 4 to slide along the operating lever 3 while rotating, increasing the flexibility and adjustability of the operation.

[0040] Operators can control the angle and force of the pressure rod 4 by rotating the operating lever 3 according to actual needs. At the same time, the position of the pressure rod 4 can be finely adjusted by sliding the pressure rod 4 on the operating lever 3 to adapt to the leveling needs of different situations, thereby improving the accuracy and adaptability of the leveling operation.

[0041] One end of the pressure rod 4 is slidably connected to the operating rod 3, and the other end passes through the support base 1 and is connected to the spinneret filter screen 5. Driven by the operating rod 3, it moves downward and directly applies pressure to the spinneret filter screen 5, pressing down and flattening the deformed and bulging parts. This effectively flattens the deformed parts of the spinneret filter screen 5. Compared with manual flattening by using a bakelite punch, the downward pressure of the pressure rod 4 is more uniform and stable, which can improve the consistency of the flattening effect and product quality, and also has higher operating efficiency.

[0042] This spinneret filter leveling device, through the coordinated operation of its components, presses down and flattens the spinneret filter 5, which has deformed and bulged due to the stamping and drawing process. This provides a flat and qualified spinneret filter 5 blank for subsequent processing steps such as punching. It is a key auxiliary device for ensuring the quality of the spinneret filter 5 in chemical fiber production.

[0043] The positioning holes of the positioning seat 17 in this device accurately position the spinneret filter screen 5, ensuring that the position is fixed each time. The pressure rod 4 is pressed down stably under the action of the operating rod 3. Compared with manual tapping for leveling, it can apply more uniform and stable pressure to the deformed parts of the filter screen, effectively reducing the problem of inconsistent leveling effect caused by differences in human operation force and position, greatly improving leveling accuracy and consistency, and thus improving product quality stability.

[0044] The operator can drive the pressure rod 4 to level the spinneret filter 5 by rotating the operating lever 3. Compared with manual tapping, the operation process is simplified and time-saving, and the leveling of multiple spinneret filter 5s can be completed quickly, meeting the efficiency requirements of large-scale production and improving production efficiency. At the same time, the pressure rod 4 of this device presses down smoothly, and the pressure and position can be reasonably controlled through the sliding adjustment functions of the operating lever 3 and the pressure rod 4, reducing damage to the spinneret filter 5, improving the product spinneret filter 5 qualification rate, and reducing production costs.

[0045] The support base 1 includes a base plate 11, support columns 12, and mounting plate 13. Support columns 12 are installed at both ends of the base plate 11. The support columns 12 are installed between the base plate 11 and the mounting plate 13. The positioning seat 17 is installed on the base plate 11, and the bracket 2 is installed on the mounting plate 13. The base plate 11 serves as the basic component of the support base 1. It is the connecting carrier between the entire device and the external working plane, ensuring that the device is placed stably. At the same time, it provides an installation position for the positioning seat 17 and ensures the stability of the positioning seat 17.

[0046] The support columns 12 play a crucial role in vertical support, transferring the weight of the mounting plate 13 and its components such as the bracket 2 and operating lever 3 to the base plate 11, maintaining the vertical structural stability of the entire device. Furthermore, the number and distribution of the support columns 12 affect the stability of the device. Evenly distributed support columns 12 at both ends of the base plate 11 ensure good stability in all directions, preventing tipping due to uneven stress.

[0047] Mounting plate 13 is used to mount bracket 2, providing a stable mounting platform for bracket 2 and ensuring that bracket 2 will not shift or shake during operation, thereby ensuring the movement accuracy of operating rod 3 and pressure rod 4. Simultaneously, it also plays a connecting and reinforcing role in the overall structure of the device, connecting components such as support column 12 and bracket 2 into a whole, enhancing the structural strength of the device. Through the synergistic effect of base plate 11, support column 12, and mounting plate 13, support base 1 greatly improves the stability and reliability of the device. Stable support ensures that the spinneret filter 5 on positioning seat 17 will not shift during leveling, ensuring leveling accuracy; at the same time, it also provides a stable foundation for the movement of operating rod 3 and pressure rod 4, enabling pressure rod 4 to accurately apply pressure to spinneret filter 5, improving the consistency of leveling effect.

[0048] The base plate 11 has a first storage slot and a second storage slot connected to the first storage slot. A pad 16 is installed in the first storage slot, and a positioning seat 17 is installed in the second storage slot. The end of the pad 16 extends into the positioning hole. The spinneret filter 5 is positioned above the pad 16. The first storage slot is used to place the pad 16, providing precise positioning and a stable installation position for the pad 16. At the same time, it restricts the horizontal movement of the pad 16, ensuring that the position of the pad 16 is fixed. This ensures that the relative positional relationship between the pad 16, the positioning seat 17, and the spinneret filter 5 is stable, allowing the pad 16 to accurately support the spinneret filter 5 and preventing displacement of the pad 16 from affecting the placement accuracy and leveling effect of the spinneret filter 5. During repeated use, the correct position of the pad 16 is maintained, improving the reusability accuracy of the device and ensuring the stable production of qualified products.

[0049] The second placement slot is used to install the positioning seat 17. It positions and fixes the positioning seat 17, ensuring that the positioning seat 17 is accurately positioned on the base plate 11 and will not shake or shift during the operation of the device. It maintains the relative position accuracy between the positioning seat 17 and other components. The second placement slot allows the positioning seat 17 to be firmly installed on the base plate 11, thereby ensuring the positional accuracy of the positioning holes on the positioning seat 17. This ensures that the spinneret filter 5 can be accurately placed in the same position each time, improving the consistency of the placement of the spinneret filter 5. This provides a stable and reliable foundation for subsequent leveling operations and helps to improve the stability of the leveling effect and the consistency of product quality.

[0050] The end of the pad 16 extends into the positioning hole of the positioning seat 17, providing bottom support for the spinneret filter 5 placed above. The pad 16 can be designed according to the shape and size of the spinneret filter 5 to provide suitable support points and support force, preventing the spinneret filter 5 from deforming or shaking during placement and leveling. In addition, the pad 16 also acts as a buffer, reducing the impact force on the spinneret filter 5 when the pressure rod 4 is pressed down.

[0051] The spinneret filter 5 is placed above the pad 16, and precise positioning is achieved through the engagement of the positioning hole on the positioning seat 17 with the end of the pad 16. The positioning seat 17 ensures the accurate horizontal position of the spinneret filter 5, while the pad 16 provides stable support in the vertical direction. Together, they maintain a fixed position and posture of the spinneret filter 5 throughout the leveling process, ensuring the positional accuracy of the spinneret filter 5 during leveling. This allows the pressure rod 4 to accurately apply pressure to the deformed areas, improving the accuracy and consistency of leveling. The stable placement method reduces leveling failures or product quality problems caused by positional deviations of the spinneret filter 5, improving production efficiency and product quality.

[0052] The operating lever 3 has a sliding groove 32, within which a sliding rod 33 is slidably mounted. A sleeve rod 34 is fitted onto the sliding rod 33, and the sleeve rod 34 is coaxially connected to the pressure rod 4. The sliding groove 32 provides a specific sliding track for the sliding rod 33, restricting its direction of movement so that it can only slide along the direction of the sliding groove 32 on the operating lever 3. In this way, precise control of the position of the sliding rod 33 is achieved, thereby indirectly controlling the positions of the sleeve rod 34 and the pressure rod 4 connected to the sliding rod 33. This greatly increases the flexibility of the device operation. The operator can flexibly adjust the downward position of the pressure rod 4 according to different deformation conditions of the spinneret filter screen 5, improving the accuracy of the leveling operation and ensuring that pressure can be accurately applied to the deformed parts.

[0053] The sliding rod 33, serving as an intermediate component connecting the operating rod 3, the sleeve rod 34, and the pressure rod 4, combines the rotational movement of the operating rod 3 with the position adjustment of the pressure rod 4. Its sliding within the sliding groove 32 drives the sleeve rod 34 and the pressure rod 4 to move synchronously, thereby changing the position of the pressure rod 4 relative to the operating rod 3 and achieving fine-tuning of the pressure rod 4's position. During the leveling process, when encountering irregular deformation of the spinneret filter 5, the operator can adjust the position of the pressure rod 4 by moving the sliding rod 33, allowing the pressure rod 4 to better align with the deformed area. This improves the adaptability and specificity of the leveling operation, further ensuring the reliability of the leveling effect.

[0054] The sleeve rod 34 serves to transmit force and stabilize the structure. It smoothly transmits the movement of the sliding rod 33 to the pressure rod 4, ensuring that the pressure rod 4 moves synchronously with the sliding rod 33, thus guaranteeing the smoothness and accuracy of the pressure rod 4's movement. Simultaneously, because the sleeve rod 34 fits tightly with the sliding rod 33 and the pressure rod 4, it enhances the stability of the entire connection structure, preventing wobbling or deviation during operation.

[0055] Reference Figure 2 and Figure 3 A limiting seat 6 is installed on the top of the support base 1. A groove 61 is formed on the limiting seat 6, and the pressure rod 4 is located within the groove 61. The width of the groove 61 is greater than the diameter of the pressure rod 4, and the width of the groove 61 is less than the diameter of the sleeve rod 34. The limiting seat 6 is used to limit and guide the pressure rod 4, ensuring that the pressure rod 4 maintains a stable trajectory during movement. It is tightly connected to the support base 1, combining its own limiting function with the stable support of the support base 1, providing a reliable constraint environment for the movement of the pressure rod 4, and improving the stability and accuracy of the pressure rod 4's movement. During the downward and upward movement of the pressure rod 4, the limiting seat 6 restricts the lateral movement range of the pressure rod 4, preventing the pressure rod 4 from shaking or deviating, ensuring that the pressure rod 4 can always vertically level the spinneret filter screen 5, thereby improving the consistency of the leveling effect and product quality.

[0056] The groove 61 is a key structure for limiting and guiding the pressure rod 4. The width of the groove 61 is greater than the diameter of the pressure rod 4, providing sufficient space for the pressure rod 4 to move smoothly up and down within the groove 61. Conversely, the width of the groove 61 is smaller than the diameter of the sleeve rod 34, preventing the sleeve rod 34 from entering the groove 61 and ensuring that the sleeve rod 34 moves normally outside the groove 61 with the pressure rod 4. Simultaneously, the larger diameter of the sleeve rod 34, when engaging with the edge of the groove 61, further restricts the lateral displacement of the pressure rod 4. When the pressure rod 4 presses down to level the spinneret filter 5, even under external interference or minor vibrations caused by the movement of the operating rod 3, the pressure rod 4 maintains a vertical downward pressure under the coordinated restraint of the groove 61 and the sleeve rod 34, accurately applying pressure to the deformed areas, effectively improving the leveling quality and reducing the product defect rate.

[0057] The end of the operating lever 3 is equipped with a handle ball 31. The handle ball 31 can evenly distribute the force applied by the operator's hand, avoiding fatigue and discomfort caused by excessive local force on the hand due to prolonged operation. The handle ball 31 increases the contact area between the operator's hand and the operating lever 3, making it easier for the operator to apply force to rotate the operating lever 3. When rotating the operating lever 3, it is easier to apply force, especially when a large operating force is required to press down and level the spinneret filter screen 5. The handle ball 31 makes it easier for the operator to complete the operation.

[0058] Reference Figure 2 and Figure 3 A base 14 is mounted on one side of the mounting plate 13 near the base plate 11, and a bracket 2 is provided on the other side. The base 14 has a cavity, within which a spring 15 is installed. A pressure rod 4 passes through the mounting plate 13 and the base 14 in sequence, with the spring 15 fitted over the pressure rod 4. The base 14 provides space for the spring 15, fixing its position and ensuring it does not shift or wobble during operation. Simultaneously, the base 14 acts as a connecting component, tightly connecting the spring 15 to the mounting plate 13, allowing the spring force to be effectively transmitted to the pressure rod 4. Furthermore, it also provides a guiding function for the pressure rod 4, guiding it to maintain a stable trajectory during its up-and-down movement.

[0059] Spring 15 serves a reset function. When the operator presses down on the operating lever 3 to drive the pressure rod 4 to level the spinneret filter 5, releasing the operating lever 3 releases the elastic potential energy of spring 15, pushing the pressure rod 4 upward to return it to its initial position, facilitating the next loading and unloading of the spinneret filter 5. Furthermore, spring 15 also provides a buffering effect during the downward pressing of the pressure rod 4, preventing excessive impact on the spinneret filter 5 and improving the ease of operation and efficiency of the spinneret filter leveling device. The automatic reset function reduces operating steps and shortens operation time, allowing operators to complete the leveling of multiple spinneret filters 5 more quickly. Simultaneously, the stable structure and the buffering protection of spring 15 improve product quality and device reliability, reduce equipment maintenance costs, and contribute to improving the leveling quality and production efficiency of the spinneret filter 5 in chemical fiber production.

[0060] A limiting element 41 is provided on the pressure rod 4. The spring 15 is located between the bottom of the base 14 and the limiting element 41. The limiting element 41 is used to limit the compression stroke of the spring 15. During the pressing process of the pressure rod 4, the limiting element 41 cooperates with the bottom of the base 14 to limit the maximum compression degree of the spring 15, avoid the spring 15 from being over-compressed and causing elastic failure or damage, and ensure that the spring 15 always works within a reasonable elastic deformation range and maintains its stable elastic performance.

[0061] The limiting component 41 can also clearly define the limit position of the pressure rod 4, ensuring that the pressure rod 4 can reach the set working position during each pressing operation, and will not be pressed too much due to operation errors or other factors. This prevents the pressure rod 4 from being pressed too much and damaging the spinneret filter screen 5. At the same time, it avoids the pressure rod 4 from generating additional impact force on the base 14, mounting plate 13 and other device components due to excessive movement, thus extending the service life of each component of the device and reducing the equipment failure rate.

[0062] The usage process of the spinneret filter screen leveling device in this application embodiment is as follows:

[0063] Preparation stage: The operator first places the spinneret filter 5 to be leveled on the positioning hole of the positioning seat 17. The positioning seat 17 is installed in the second storage slot of the base plate 11 to ensure a stable position. The positioning hole on the positioning seat 17 mates with the end of the pad 16 in the first storage slot to accurately position the spinneret filter 5 so that it is directly below the pressure rod 4. At this time, the pressure rod 4 is in the initial raised position under the action of the spring 15, and the pressure rod 4 is located in the groove 61 of the limiting seat 6. The groove 61 limits and guides the pressure rod 4, ensuring that the position of the pressure rod 4 is stable.

[0064] During the pressing and leveling stage: The operator holds the handle ball 31 at the end of the operating rod 3 and rotates the operating rod 3 with the bracket 2 as the fulcrum. The operating rod 3 has a sliding groove 32, and the sliding rod 33 in the sliding groove 32 moves with the rotation of the operating rod 3. The sleeve rod 34 sleeved on the sliding rod 33 drives the pressure rod 4 coaxially connected to it to move downward synchronously. If it is necessary to fine-tune the position of the pressure rod 4, the operator can achieve this by controlling the sliding of the sliding rod 33 in the sliding groove 32. The pressure rod 4 gradually moves downward towards the spinneret filter 5. When it contacts the deformed part of the spinneret filter 5, the pressure rod 4 applies pressure to the deformed part to level it as the operating rod 3 continues to rotate. During the pressing process of the pressure rod 4, the spring 15 in the base 14 on the side of the mounting plate 13 near the bottom plate 11 is compressed. The spring 15 plays a certain buffering role to prevent the pressure rod 4 from applying too much impact force to the spinneret filter 5. At the same time, the limiting member 41 on the pressure rod 4 moves downward together with the pressure rod 4. When the pressure rod 4 reaches the set downward pressure limit position, the limiting member 41 contacts the bottom of the base 14, limiting the spring 15 to compress further and preventing the pressure rod 4 from being pressed down too much and causing damage to the spinneret filter screen 5 and other parts of the device.

[0065] Reset Phase: After the leveling operation is completed, the operator releases the operating lever 3. At this time, the compressed spring 15 releases its elastic potential energy, pushing the pressure rod 4 upward, thus restoring the pressure rod 4 to its initial position. The spring 15 is located between the bottom of the base 14 and the limiting member 41. During the reset process, the elastic force of the spring 15 is transmitted to the pressure rod 4 through the limiting member 41, ensuring that the pressure rod 4 rises smoothly. During the rise of the pressure rod 4, it drives the sleeve rod 34 and the sliding rod 33 to move together. The sliding rod 33 slides upward within the sliding groove 32. Finally, the pressure rod 4 returns to its initial position, making it convenient for the operator to remove the leveled spinneret filter 5 and perform the next leveling operation.

[0066] This spinneret filter leveling device achieves efficient and precise leveling of the spinneret filter 5. Compared with the traditional manual leveling method, it greatly improves the consistency of leveling effect and operational efficiency, reduces labor intensity, reduces damage to the spinneret filter 5, and improves product quality and production efficiency.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
