Description

Technical Field

[0001] This utility model relates to the field of polyester filament heat setting equipment. Background Technology

[0002] Polyester filament heat setting equipment is a special equipment used to heat set polyester filaments. Its main purpose is to eliminate the internal stress generated during the processing of polyester filaments, so that the fiber molecular chain segments move and rearrange, thereby achieving effects such as dimensional stability, shape fixation, and improved wrinkle resistance and elasticity.

[0003] According to Chinese Patent CN202223563989.6, the invention incorporates a traction roller, a moving plate, an intermediate roller, and a buffer spring. During use, polyester filaments to be shaped are placed sequentially between the traction rollers, with the filaments interlaced. When the filaments are wound up, they begin to move between the traction rollers. As the filaments move, the traction rollers begin to rotate synchronously. The faster the filaments move, the greater the rotation amplitude of the traction rollers. Simultaneously, the intermediate rollers at both ends reciprocate to compress the buffer springs, causing the moving plate to move vertically. The moving plate has a limited range of motion; by utilizing the buffer springs to absorb some vibration, the amplitude of the traction roller swaying is reduced, improving the stability of use.

[0004] Although the traction roller, moving plate, intermediate roller and buffer spring in the application can effectively deal with the shaking problem, during use, the lint adsorbed on the polyester yarn may cover its surface and form a thin fiber layer. This fiber layer may hinder the heat transfer during the heat setting process, resulting in uneven heating of the polyester yarn. Therefore, we propose a polyester yarn heat setting device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a polyester yarn heat setting device, which has the following beneficial effects:

[0017] 1. This polyester filament heat setting equipment effectively adsorbs impurities on the surface of the polyester filament through the lint-removing tape in the dust removal structure. This removes various impurities such as dust particles and lint, allowing the polyester filament to enter subsequent heat setting and other processing steps in a relatively pure and clean state. This avoids impurities from mixing into the interior of the polyester filament or adhering to its surface, affecting the heat setting effect. It helps to ensure the final physical properties and appearance quality of the polyester filament, such as making the strength and elasticity of the polyester filament more stable, the surface smoother and flatter, improving the overall quality of the product, and better meeting the quality requirements of polyester filament in different subsequent application scenarios.

[0018] 2. This polyester filament heat setting equipment features a unique structural design that simplifies the replacement of lint-removing tape. The old tape can be easily torn off using the toothed pins, and the coordinated use of components such as the connecting disc, the first rotating shaft, and the second rotating shaft, along with the guiding groove, allows operators to easily install and secure the new lint-removing tape. This convenient maintenance method saves equipment maintenance time, further reduces the impact on production schedules, and improves overall production efficiency.

[0019] 3. This polyester filament heat setting equipment uses a rotating ball that rotates within a spherical connecting groove, thereby driving the U-shaped block to adjust its angle. This allows the dust removal structure to flexibly change the angle and position of the lint-removing tape according to the actual transmission position and direction of the polyester filament, as well as the characteristics of polyester filaments of different specifications. This ensures that the tape always maintains good contact with the polyester filament, better fulfills its dust removal function, and enhances the equipment's adaptability to different production conditions.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 A polyester filament heat setting device includes columns 1, a housing 2, a hot air blower 3, a heating assembly 4, rollers 5, a filament feeding and take-up assembly 6, and a first through hole 7. The housing 2 is fixedly connected to the top of four sets of columns 1. The filament feeding and take-up assembly 6 is respectively installed on both sides of the housing 2. The hot air blower 3 is fixedly connected to the top of the housing 2. The heating assembly 4 is fixedly connected to the bottom of the inner wall of the housing 2. Three sets of rollers 5 are fixedly connected to one side of the inner wall of the housing 2. The first through hole 7 is opened at both ends of the housing 2. The device also includes:

[0027] A dust removal structure is installed on the inner wall of column 1, which is used to remove impurities from polyester filaments.

[0028] Furthermore, a fixing block 8 is fixedly connected to the inner wall of one end of the column 1. A second through hole 9 is opened on the outer side of the fixing block 8, and the second through hole 9 corresponds to one of the first through holes 7. Two sets of spherical connecting grooves 17 are opened on one side of the fixing block 8 at the corresponding position on the outer side of the second through hole 9. Rotating balls 10 are rotatably connected to the inner walls of the two sets of spherical connecting grooves 17. When the polyester filament enters from the first through hole 7 at one end of the box body 2 and passes through the second through hole 9 of the fixing block 8, it begins to enter the effective range of the dust removal structure.

[0029] Furthermore, a connecting rod 11 is fixedly connected to one end of the rotating ball 10, and a U-shaped block 12 is fixedly connected to one end of the connecting rod 11. A nail tooth 13 is fixedly connected to the top of the U-shaped block 12, and connecting posts 18 are fixedly connected to both sides of the U-shaped block 12. As the lint-repellent tape 15 continuously absorbs impurities, after a certain period of use, its surface will gradually be covered with dust and lint, resulting in a significant decrease in adhesion and the inability to effectively absorb new impurities. At this time, it is necessary to replace it. Before replacement, the angle of the relevant components needs to be adjusted to ensure smooth operation. The U-shaped block 12 is connected to the rotating ball 10 through the connecting rod 11, and the rotating ball 10 can rotate freely in the two sets of spherical connecting grooves 17 on the fixed block 8. The operator can manually operate the rotating ball 10 to rotate in the spherical connecting grooves 17 according to the actual situation, thereby driving the connecting rod 11 and the U-shaped block 12 connected to it to adjust their angles.

[0030] Furthermore, a connecting plate 14 is inserted into the other end of the connecting post 18. A first connecting groove 19 is provided at the axis of the connecting plate 14, and the first connecting groove 19 is inserted into the other end of the connecting post 18. A guide groove 16 is provided on one side of the connecting plate 14 at a position corresponding to the outer side of the first connecting groove 19. The operator begins to tear off the old lint tape 15, gently pulling the lint tape 15, which is covered with dust and lint, towards the direction of the nail teeth 13, so that the lint tape 15 gradually approaches the nail. The operator applies pressure to the lint tape 15, pressing it against the teeth 13. Because the teeth 13 are sharp and protrude, they will either pierce the lint tape 15 or hook onto its surface during pressing. The operator then continues to apply force in the original pulling direction to gradually tear and remove the lint tape 15, thus making room for the installation of a new lint tape.

[0031] Furthermore, the dust removal structure is provided in two sets and is located on both sides of the U-shaped block 12.

[0032] Furthermore, the dust removal structure includes lint-removing tape 15, a first connecting groove 19, a first rotating shaft 20, a connecting block 21, a second rotating shaft 22, and a second connecting groove 23. The first rotating shaft 20 is fixedly connected to the other side of the connecting disc 14. The connecting block 21 is fixedly connected to one side of the first rotating shaft 20. The second rotating shaft 22 is sleeved on the outer side of the first rotating shaft 20. The inner wall of the second rotating shaft 22 has a second connecting groove 23, and the second connecting groove 23 is engaged with the connecting block 21. Lint-removing tape 15 is sleeved on the outer side of the second rotating shaft 22. 5. At this point, the polyester filament will approach and come into contact with the lint-removing tape 15 placed on both sides of the U-shaped block 12. Due to the adhesiveness of the lint-removing tape 15, at the instant the polyester filament comes into contact with it, various impurities attached to the surface of the polyester filament, such as tiny dust particles, loose lint, and other fine dirt mixed in during the production process, will be adsorbed onto the lint-removing tape 15 due to the adhesive effect. As the polyester filament continues to move forward steadily, the impurities on its entire surface will be continuously adsorbed and removed by the lint-removing tape 15, thereby enabling the polyester filament to be relatively clean and pure. The state continues to be transmitted within the equipment, providing a good foundation for subsequent heat setting and other processing steps, avoiding impurities from adversely affecting the processing effect. After prolonged use, when the lint-retaining tape 15 is used up, a brand new lint-retaining tape 15 needs to be replaced. When installing the new lint-retaining tape 15, first, the lint-retaining tape 15 needs to be fitted onto the outside of the second rotating shaft 22, so that the two are tightly fitted together. Then, align the second rotating shaft 22 with the connecting block 21 on one side of the first rotating shaft 20 through the connecting groove 23 opened on its inner wall. Shaft 22 is pushed toward the first rotating shaft 20, so that the connecting groove 23 and the connecting block 21 are accurately engaged. In this way, the second rotating shaft 22 is stably connected to the first rotating shaft 20. Then, the guide groove 16 on 14 is aligned with the connecting post 18, so that the connecting post 18 is inserted into the connecting groove. This completes the installation and fixing of the new lint-adhesive tape 15, so that the new lint-adhesive tape 15 can be in the correct position and remain stable, regaining its ability to adsorb impurities, and preparing for the dust removal operation when the polyester filament passes through this place again.

[0033] Structural Description:

[0034] 1. Columns: The columns are the supporting structure of the polyester filament heat setting equipment. There are four sets in total. Their tops are fixedly connected to the box body, providing a stable support foundation for the entire equipment, ensuring the stability of the equipment during operation, and enabling all components to be installed in an orderly manner and work together in accordance with design requirements.

[0035] 2. Housing: The housing is the main outer shell structure of the polyester filament heat setting equipment. It is located on top of the four sets of columns. The filament feeding and receiving components are set on both sides. The hot air fan is fixedly connected to the top, and the heating components are fixedly connected to the bottom of the inner wall. Three sets of rollers are also fixedly connected to one side of the inner wall, and the first through holes are opened at both ends. It provides a relatively closed operating space for the polyester filament transmission, heating and setting processes, and is the core load-bearing part of the entire heat setting process.

[0036] 3. Hot air blower: The hot air blower is a heating and air supply component installed on the top of the chamber. By supplying hot air into the chamber, it works together with the heating components inside the chamber to create a suitable high-temperature environment, allowing the polyester filaments inside the chamber to be heated and heat-set, thereby changing the molecular structure of the polyester filaments and improving their performance and stability.

[0037] 4. Heating Component: The heating component is fixedly connected to the bottom of the inner wall of the chamber. As one of the key heat sources for heat setting of polyester filaments, it works in conjunction with the hot air blower to continuously generate heat, ensuring that the required temperature conditions can be reached and maintained inside the chamber. This causes the molecular chain segments inside the polyester filaments to move and rearrange at high temperatures, thereby achieving the purpose of heat setting.

[0038] 5. Rollers: The rollers are fixedly connected to one side of the inner wall of the box. There are three sets in total. Their main function is to guide the polyester yarn to be transported smoothly in the box along the predetermined path, ensuring that the polyester yarn can be heated evenly when passing through the high temperature area created by the hot air blower and heating components, ensuring the consistency of the heat setting effect. At the same time, they also provide a certain support for the polyester yarn, so that it can complete the entire heat setting process smoothly.

[0039] 6. Yarn feeding and winding components: The yarn feeding and winding components are respectively set on both sides of the box and are used to orderly feed and wind up the polyester yarn entering and leaving the box, ensuring the continuous transmission of polyester yarn in the entire heat setting equipment. They can also sort and collect polyester yarn according to actual production needs, which is convenient for further processing or storage.

[0040] 7. First through hole: The first through hole is opened at both ends of the box and is the channel for polyester yarn to enter and exit the box. One end allows the polyester yarn to enter the box to start heat setting and other processes, while the other end facilitates the polyester yarn to pass out of the box after heat setting and enter the subsequent process, ensuring the smooth passage of polyester yarn in the equipment.

[0041] 8. Fixing block: The fixing block is fixedly connected to the inner wall of one end of the column. A second through hole is opened on its outer side. The second through hole corresponds to the first through hole at one end of the box and is the necessary channel for polyester filament to enter the dust removal structure. At the same time, two sets of spherical connecting grooves are opened on one side of the fixing block at the corresponding position of the outer side of the second through hole, which provides the basic structural conditions for the installation of the rotating ball and the angle adjustment of subsequent related components.

[0042] 9. Second through hole: The second through hole is located on the outside of the fixed block and corresponds to the first through hole of the box. It is a transition channel for polyester filament to enter the dust removal structure from the box, so that the polyester filament can accurately enter the area where the dust removal structure is located, and then interact with the various components in the dust removal structure to start the impurity removal process.

[0043] 10. Rotating Ball: The rotating ball is rotatably connected to the inner wall of the two sets of spherical connecting grooves of the fixed block. One end of the ball is connected to the U-shaped block through a connecting rod. It can rotate freely in the spherical connecting groove. The operator can manually operate the U-shaped block to adjust the angle, so that the lint-removing tape in the dust removal structure can flexibly change its angle and position according to the actual transmission of polyester filaments, better adhere to the polyester filaments, and enhance the dust removal effect.

[0044] 11. Connecting rod: One end of the connecting rod is connected to the rotating ball, and the other end is fixedly connected to the U-shaped block. It plays the role of transmitting the rotation of the rotating ball and converting the rotation of the rotating ball into the angle change of the U-shaped block, thereby driving the U-shaped block and its related dust removal components to adjust their positions, ensuring that the entire dust removal structure can adapt to the dust removal needs of polyester filaments under different working conditions.

[0045] 12. U-shaped block: The U-shaped block is connected to the rotating ball via a connecting rod. It has a nail tooth fixedly connected to its top and connecting columns fixedly connected to both sides. It is an important connecting and load-bearing component in the dust removal structure. It not only supports the nail tooth to assist in the operation of replacing lint tape, but also plays a key supporting and connecting role in the installation, fixing and position adjustment of lint tape through the connecting columns and other components.

[0046] 13. Nail teeth: The nail teeth are fixedly connected to the top of the U-shaped block. They are sharp and protrude to a certain height. They play an important role when the lint tape needs to be replaced. By pulling the lint tape, which is covered with impurities and has lost its stickiness, towards the nail teeth and pressing it onto the nail teeth, the operator can easily tear off the old lint tape by using the nail teeth's ability to cut and hook the tape surface. This makes it easier for the operator to continue to remove the old lint tape afterward.

[0047] 14. Connecting plate: A first connecting groove is provided at the center of the connecting plate. One side of the connecting plate is inserted into the other end of the connecting column through the first connecting groove, and the other side is fixedly connected to the first rotating shaft. A guide groove is provided on one side of the connecting plate at a position corresponding to the outside of the first connecting groove. The guide groove plays a key connecting and guiding role in the installation and fixing of the lint tape. It not only ensures the stable connection between the relevant components, but also makes it convenient for the operator to operate according to the guide and successfully complete the installation of the new lint tape.

[0048] 15. Lint-removing tape: Lint-removing tape is attached to the outside of the second rotating shaft. It is sticky and is the core component of the dust removal structure for removing impurities from the surface of polyester filaments. When polyester filaments pass by it, the tape adsorbs dust particles, lint, and other impurities from the surface of the polyester filaments, making the polyester filaments clean and pure. This provides good conditions for subsequent heat setting and other processing steps. After a period of use, it can be easily replaced through the corresponding structure to maintain good dust removal capabilities.

[0049] 16. Guide groove: The guide groove is located on one side of the connecting plate, corresponding to the outer side of the first connecting groove. When installing new lint tape, its main function is to provide accurate guidance for the connecting post to be inserted into the first connecting groove of the connecting plate, ensuring that the relevant components can be accurately aligned and smoothly connected, helping operators to complete the installation and fixing of lint tape more conveniently, and improving the efficiency of equipment maintenance.

[0050] 17. Spherical connecting groove: The spherical connecting groove is opened on one side of the fixed block and at the corresponding position on the outside of the second through hole. There are two sets. The inner wall of each groove is rotatably connected to a rotating ball, providing the rotating ball with a rotatable space and a limited movement trajectory. This allows the rotating ball to rotate flexibly inside the groove, thereby driving the connected components to achieve angle adjustment. This ensures that the dust removal structure can adapt to the needs of polyester filament transmission and dust removal under different conditions.

[0051] 18. Connecting column: The connecting column is fixedly connected to both sides of the U-shaped block, and its other end is inserted into the first connecting groove of the connecting plate. In the entire dust removal structure, it plays the role of connecting the U-shaped block and the connecting plate, transmitting the force and movement between the components, and cooperating with the guide groove to participate in the installation, disassembly and angle adjustment of the lint-removing tape, ensuring that all components of the dust removal structure work together.

[0052] 19. First connecting groove: The first connecting groove is located at the center of the connecting plate. It is used to insert with the other end of the connecting column, so that the connecting plate and the connecting column can be firmly connected. This lays the foundation for the connection and cooperation between various components in the entire dust removal structure, and ensures the stability and integrity of the structure during the installation, use and adjustment of the lint tape and related component angles.

[0053] 20. First rotating shaft: The first rotating shaft is fixedly connected to the other side of the connecting plate. A connecting block is fixedly connected to one side of the shaft, and a second rotating shaft is sleeved on the outside. It is an important component of the lint tape installation and fixing structure. It is engaged with the second rotating shaft through the connecting block and the second connecting groove to realize the bearing and fixing of the lint tape, ensuring that the lint tape can be in the correct position and stably perform its dust removal function.

[0054] 21. Connecting block: The connecting block is fixedly connected to one side of the first rotating shaft. Its shape and size match the second connecting groove opened on the inner wall of the second rotating shaft. It is used to realize the snap-fit ​​connection between the first rotating shaft and the second rotating shaft, thereby firmly fixing the lint-removing tape sleeved on the outside of the second rotating shaft, ensuring that the lint-removing tape will not loosen or shift during operation, and maintaining a good dust removal effect.

[0055] 22. Second Rotating Shaft: The inner wall of the second rotating shaft is provided with a second connecting groove, which is used to engage with the connecting block on the first rotating shaft. The outer side is fitted with lint-removing tape, which is a key component for installing and fixing the lint-removing tape. In cooperation with the first rotating shaft, it not only ensures the firm installation of the lint-removing tape, but also facilitates the corresponding disassembly operation when the lint-removing tape needs to be replaced, so that the entire dust removal structure can operate continuously and effectively.

[0056] 23. Second connecting groove: The second connecting groove is opened on the inner wall of the second rotating shaft and matches the connecting block on the first rotating shaft. Through the snap-fit ​​between the two, the second rotating shaft can be stably sleeved on the outside of the first rotating shaft, thereby reliably fixing the lint tape in the corresponding position. This provides structural protection for the normal use of the lint tape in dust removal work and subsequent replacement operations.

[0057] Working principle:

[0058] When the polyester filament enters through the first through-hole 7 at one end of the housing 2 and passes through the second through-hole 9 of the fixing block 8, it begins to enter the effective range of the dust removal structure. At this time, the polyester filament approaches and comes into contact with the lint-removing tape 15 located on both sides of the U-shaped block 12. Due to the adhesiveness of the lint-removing tape 15, at the moment the polyester filament comes into contact with it, various impurities attached to the surface of the polyester filament, such as tiny dust particles, loose lint, and other fine dirt mixed in during the production process, will be adsorbed onto the lint-removing tape 15 due to the adhesive effect. As the polyester filament continues to move forward steadily, the impurities on its entire surface will be continuously adsorbed by the lint-removing tape 15. This ensures that the polyester filaments continue to be transported within the equipment in a relatively clean and pure state, providing a good foundation for subsequent heat setting and other processing steps, and avoiding the adverse effects of impurities on the processing results. As the lint-repellent tape 15 continuously absorbs impurities, after a certain period of use, its surface will gradually become covered with dust and lint, resulting in a significant decrease in adhesion and the inability to effectively absorb new impurities. At this point, it needs to be replaced. Before replacement, the angles of the relevant components need to be adjusted to ensure smooth operation. The U-shaped block 12 is connected to the rotating ball 10 via the connecting rod 11, and the rotating ball 10 can be fixed on the fixed block 8. The two sets of spherical connecting grooves 17 on the upper part can rotate freely. The operator can manually operate the rotating ball 10 to rotate within the spherical connecting groove 17 according to the actual situation, thereby driving the connecting rod 11 and the U-shaped block 12 connected to it to adjust the angle, so that the position and angle of the lint tape 15 can better fit the requirements of the subsequent replacement operation, ensuring that it can accurately cooperate with the nail teeth 13 and other components, facilitating the upcoming action of tearing off the old tape. After the angle adjustment is completed, the operator begins to tear off the old lint tape 15, gently pulling the lint tape 15, which is covered with dust and lint, towards the direction of the nail teeth 13, so that the lint tape is removed. The lint tape 15 is gradually brought closer to the nail teeth 13, and its surface is brought into contact with the nail teeth 13. Then, the operator applies a certain pressure to the nail teeth 13 and presses the lint tape 15. Because the nail teeth 13 are sharp and have a certain protrusion, during the pressing process, the nail teeth 13 will pierce into the inside of the lint tape 15 or hook onto the surface of the tape. At this time, the operator continues to pull in the original direction and can gradually tear and pull off the lint tape 15, thus removing the old lint tape 15 and making room for the new lint tape. After long-term use, when the tape on the lint tape 15 is used up, a brand new lint tape 15 needs to be replaced.When installing the new lint-repellent tape 15, first, slip the lint-repellent tape 15 over the outside of the second rotating shaft 22, ensuring a tight fit. Next, align the connecting groove 23 on the inner wall of the second rotating shaft 22 with the connecting block 21 on one side of the first rotating shaft 20, and push the second rotating shaft 22 towards the first rotating shaft 20, ensuring the connecting groove 23 and connecting block 21 are accurately engaged. This method achieves a secure fit of the second rotating shaft 22 onto the first rotating shaft 20. Then, align the guide groove 16 on 14 with the connecting post 18, inserting the connecting post 18 into the connecting groove. This completes the installation and fixing of the new lint-repellent tape 15, ensuring it is in the correct position and stable, regaining its ability to adsorb impurities, and preparing for subsequent dust removal operations when polyester filaments pass through this area again.
