Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, specifically relating to a spinning and spooling production system. Background Technology

[0002] Melt spinning is the most commonly used process in spinning production. The melt spinning process includes the following steps: preparation of the spinning melt raw material; extrusion of the melt raw material through the micropores of a spinneret or spinneret to form a fine stream; stretching, cooling, and solidification of the melt stream to form filamentous fibers; and fiber winding.

[0003] The stretching, cooling, and solidification of the melt are typically completed within the spinning box. Melts of different materials emerge from the spinneret as fine streams and are stretched under the influence of gravity and a tension mechanism. The melt streams usually solidify after stretching within 50-80 cm of the spinneret. The solidified filaments then enter the tension mechanism, where they maintain a fixed shape under constant tension before entering the winding machine for winding. Currently, the spinning box height is fixed, and the tension mechanism is usually located on the outlet side of the spinning box, meaning the distance between the tension mechanism and the spinneret is fixed. Therefore, regardless of the melt material, the fine streams exiting the spinneret must travel this fixed distance before entering the tension mechanism, where they are under tension and stretched by the subsequent winding machine. Often, the process from melt stream formation to stretching and solidification is completed in the initial section of this fixed distance, leaving the latter section as an extended deformation zone. Although the filaments are already solidified at this point, the tension mechanism maintains the tension, and the subsequent winding machine can still cause excessive stretching of the filaments within this extended deformation zone. Excessive stretching may cause excessive deformation of filamentous fibers; during subsequent processing, the breakage rate and fuzz rate of filamentous fibers may increase due to the effects of excessive stretching. Summary of the Invention

[0004] This invention provides a spinning and winding production system that modifies the tension mechanism at the outlet of the existing spinning box, allowing it to move and adjust vertically relative to the spinning box. This allows for changes in the stretching, cooling, and solidification distance of the melt stream. The position of the tension mechanism is adjusted according to the length required for different melt materials to stretch, cool, and solidify into fibers after exiting the spinneret. This ensures that the fibers immediately enter the tension structure after stretching, maintaining stable tension and a fixed shape before winding. By setting the stretching distance according to different melt materials, this invention eliminates unnecessary extended deformation zones and avoids problems such as increased breakage and fuzzing rates that may result from excessive fiber stretching.

[0060] The beneficial effects of this invention are:

[0061] This invention provides a spinning and spooling production system, wherein the tension mechanism on the outlet side of the spinning box is configured to be movable up and down relative to the spinning box; the distance between the tension mechanism and the spinning head is set according to the distance required for different spinning melt materials to form a fine fluid from the spinneret, and then to the fine fluid being stretched, cooled, and solidified; the tension mechanism provides tension, and the rear winding machine rotates and stretches the fiber so that it is just stretched to the standard and cooled and solidified before entering the rear of the stretching mechanism; this avoids the fiber being overstretched, which would increase the breakage rate and fuzz rate during later fiber use.

[0062] The isolation backplate inside the spinning box can be folded or extended synchronously with the up-and-down movement of the tension mechanism; this avoids the tension mechanism lowering and adjusting, causing the stretching deformation zone to grow, while the isolation backplate is insufficient to cover a portion of the area below the stretching deformation zone.

[0063] The spinning box creates a low-temperature environment by expelling hot air, exchanging it with a refrigerant to form cold air, and then introducing it back into the spinning box. This allows the molten fiber to cool and solidify. An air diffuser is installed to evenly distribute the cold air within the spinning box. Several S-shaped condensate pipes are installed on the back side of the isolation back plate, filled with coolant. The cold air blown by the air diffuser onto the coolant pipes and through the perforations in the isolation back plate further enhances the low-temperature effect of the cold air within the spinning box and directly blows the cold air onto the fiber, allowing the fiber to cool and solidify evenly and rapidly.

[0074] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0075] Example 1: A spinning and spooling production system, comprising: hopper 1, screw extruder 2, metering pump 3, spinning box 4, spinneret 8, tension mechanism and tension structure lifting assembly;

[0076] like Figure 1As shown, the raw materials used for spinning production are melted at high temperature to form a molten material, which then enters the screw extruder 2 through the hopper 1. Under the output action of the screw extruder 2, the molten material is delivered from the outlet of the screw extruder 2 through the conveying pipe to the top of the spinning box 4. A metering pump 3 is installed on the conveying pipe. Several branch pipes are arranged on the upper surface inside the spinning box 4, and the aforementioned conveying pipe is connected to these branch pipes. A set of spinnerets 8 is correspondingly installed at the lower end of each branch pipe. The metering pump 3 pumps the molten material quantitatively into the spinneret 8, and the molten material is ejected through the fine holes in the spinneret 8, forming a fine fluid in the spinning box 4.

[0077] The fine fluid is stretched and cooled in the spinning box 4 to form filamentous fibers. The fibers are output from the spinning box 4 and enter two sets of guide discs 6 set below the spinning box 4. The guide discs 6 stabilize the tension of the fibers and prevent them from being stretched by tension. After passing through the guide discs 6, the fibers reach the winding machine 7 and are wound onto the drum, completing the winding after spinning.

[0078] Typically, the aforementioned tension mechanism is located below the outlet of the spinning box 4, that is, between the winding machine 7 and the spinning box 4. As the microfilament passes through the spinning box 4, it is continuously stretched under the action of the tension mechanism. However, different spinning materials have different properties, which means that the time required for them to form from microfilament, reach standard stretching, and cool and solidify is different, that is, the distance required for the above process to be completed within the spinning box 4 is different. Some materials may not require excessively long continuous stretching. Excessive stretching will lead to a decrease in the tensile stress of the final fiber, and the breakage rate and fuzz rate of the fiber will increase during later use.

[0079] like Figure 2 As shown, in this embodiment, the tension mechanism is set inside the spinning box 4, and a tension mechanism lifting assembly is set inside the spinning box 4, with the tension mechanism mounted on the lifting assembly. Under the action of the lifting assembly, the tension mechanism can move up and down in the vertical direction relative to the spinning box 4, which means that the distance from the fluid output from the spinneret 8 to the tension mechanism can be changed.

[0080] like Figure 2 As shown, the tension mechanism lifting assembly includes: slide rail 401, electrically controlled slider 903, lifting guide frame 402, and linkage rod 9031;

[0081] A slide rail 401 is installed on each of the left and right sides inside the spinning box 4. The upper and lower ends of the slide rail 401 are connected to the top and bottom surfaces of the spinning box 4, respectively. Each slide rail 401 is movably mounted with a set of electrically controlled sliders 903. Under control and drive, the electrically controlled sliders 903 move up and down along the slide rail 401. The electrically controlled sliders 903 are existing products, and their structure and control circuit structure are existing technologies. People skilled in the art are capable of selecting and implementing the electrically controlled sliders 903. The detailed structure of the electrically controlled sliders 903 will not be described here.

[0082] A lifting guide frame 402 is installed directly in front of each slide rail 401; a tension mechanism is movably installed between two lifting guide frames 402; a linkage rod 9031 is installed between the two ends of the tension mechanism and the electrically controlled slider 903;

[0083] The electrically controlled slider 903 moves on the slide rail 401, and under the action of the linkage rod 9031, the tension mechanism can move up and down relative to the lifting guide frame 402 in a synchronized manner.

[0084] like Figure 2 As shown, the tension mechanism described above includes: a tension wheel 10, a tension rotating rod 1001, and a motor 11;

[0085] Both ends of the tension rotating rod 1001 pass through the through slots 4021 opened on the two lifting guide frames 402 respectively; and there is no connection between the tension rotating rod 1001 and the through slots 4021 on the lifting guide frame 402; the tension rotating rod 1001 can move up and down relative to the lifting guide frame 402; one end of the tension rotating rod 1001 is connected to the rotor of the motor 11, and the other end of the tension rotating rod 1001 is rotatably connected to the side stop block, and the tension rotating rod 1001 can rotate relative to the side stop block;

[0086] Several tension wheels 10 are fixedly arranged at equal intervals on the tension rotating rod 1001; after the fluid from the spinneret 8 forms fibers, it passes through the tension wheels 10 and is then output from the spinning box 4; the tension wheels 10 generate tension on the fluid above the tension mechanism, thereby stretching it; the motor 11 rotates, which drives the tension rotating rod 1001 to rotate, and the tension rotating rod 1001 drives the tension wheels 10 to rotate. When the tension rotating rod 1001 rotates the tension wheels 10 to a certain position... Figure 2When the tension wheel 10 is in the vertically upward position, the tension on the fluid above the tension mechanism is minimal. When the tension rotating rod 1001 rotates the tension wheel 10 to the horizontally outward position, the tension on the fluid above the tension mechanism is maximized. Therefore, the tension on the fluid can be adjusted by rotating the tension wheel 10 to change its orientation. However, under normal circumstances, to ensure that the fluid is sufficiently stretched before cooling and solidifying to form fibers, the tension is adjusted to the maximum. Furthermore, when the tension wheel 10 is in the horizontally outward position, the tangent of the outer edge of the tension wheel 10 and the tangent of the outer edge of the guide plate 6 below are kept as close as possible to the same vertical plane. This ensures that the fibers exiting the tension mechanism immediately enter the guide plate 6, maintaining stable tension and avoiding excessive tension fluctuations. If the tension increases upon reaching the guide plate 6, it may cause secondary stretching of the fibers; if the tension decreases upon reaching the guide plate 6, it will affect the winding effect, resulting in loose winding.

[0087] A first linkage rod 9031 is installed between the motor 11 controlling the tension rotating rod 1001 and one set of electrically controlled sliders 903; a second linkage rod 9031 is installed between the side stop block at the other end of the tension rotating rod 1001 and another set of electrically controlled sliders 903. When it is necessary to adjust the vertical distance between the tension mechanism and the spinneret 8, it is only necessary to control the electrically controlled slider 903 to rise and fall. Driven by the electrically controlled slider 903, the two linkage rods 9031 will rise and fall accordingly, and the linkage rods 9031 will drive the tension rotating rod 1001 and the tension wheel 10 on it to rise and fall synchronously. The vertical distance between the tension mechanism and the spinneret 8 can be adjusted to meet the distance of different spinning materials from fluid formation to cooling and shaping after standard stretching; and to avoid the fiber being overstretched after shaping. After the fluid reaches the tension mechanism and is output from the tension mechanism, it means that the stretching is completed and a fixed fiber structure has been formed. Thereafter, a stable and constant tension needs to be maintained before entering the winding machine.

[0088] As a preferred embodiment, since a motor 11 is provided at one end of the tension rotating rod 1001, if the motor 11 does not have any auxiliary support structure, the weight of the two ends of the tension rotating rod 1001 may become unbalanced.

[0089] like Figure 3 As shown, a motor support plate 1101 is provided below the motor 11. There is no connection structure between the motor support plate 1101 and the lifting guide frame 402. A motor diagonal brace 1102 is provided on each side of the motor support plate 1101.

[0090] The first end of the motor diagonal brace 1102 is connected to the side of the motor support plate 1101, and the second section of the motor diagonal brace 1102 is movably embedded in the side guide groove 4022 opened on the side of the lifting guide frame 402. The motor support plate 1101 and the motor diagonal brace 1102 can move up and down with the motor 11 and play an auxiliary supporting role for the motor 11, avoiding the tension rotating rod 1001 from supporting the motor 11 and causing the two ends of the tension rotating rod 1001 to become unbalanced.

[0091] Example 2: Based on Example 1, under normal circumstances, an isolation back plate is installed in the vertical direction inside the spinning box 4; the purpose is to prevent the fine fluid coming out of the spinneret from breaking or other situations from directly adhering to the back plate of the spinning box 4.

[0092] In Example 1, the vertical distance between the tension mechanism and the spinneret 8 is adjustable. If the isolation backplate is too short, the area above the tension mechanism may not be covered by the isolation backplate when the tension mechanism descends. If the isolation backplate is laid vertically throughout the spinning box 4, the portion of the isolation backplate below the tension mechanism will not function.

[0093] like Figure 4 As shown, in this embodiment, the isolation back plate 9 is configured to fold or extend synchronously with the lifting and lowering of the tension mechanism; the isolation back plate 9 is disposed between two slide rail rods 401, and the isolation back plate 9 includes: a sub-plate, a hinge shaft rod 902 and a fixing block 904; several sub-plates are connected by hinge shaft rods 902 to form the isolation back plate 9 as a whole; a crossbar is provided on the upper edge of the uppermost sub-plate and the lower edge of the lowermost sub-plate.

[0094] A fixing block 904 is installed at each end of the upper crossbar; the fixing block 904 is fixedly installed on the slide rail 401;

[0095] A set of electrically controlled sliders 903 is provided at each end of the lower crossbar, and the electrically controlled sliders 903 are movably mounted on the slide rail 401; the electrically controlled sliders 903 are the electrically controlled sliders 903 used to drive the tension mechanism to rise and fall as described in Embodiment 1;

[0096] The electrically controlled slider 903 moves up or down to raise or lower the tension mechanism; at the same time, the electrically controlled sliders 903 at both ends drive the crossbar at the lowest edge of the isolation back plate 9 to move up or down, which can push the isolation back plate 9 to fold or extend it.

[0097] In a preferred embodiment, since the lifting mechanism and the isolation backplate 9 are not on the same vertical plane, there is a gap between them; in order to cover this gap as well, Figure 4As shown, an extension slope 901 is installed on the crossbar at the lower edge of the lowest sub-plate of the isolation backplate 9. The first side edge of the extension slope 901 is connected to the crossbar. The extension slope 901 is slightly inclined so that the second side edge of the extension slope 901 extends to the tension mechanism. In this way, the extension slope 901 can cover and fill the gap between the lower edge of the isolation backplate 9 and the tension mechanism. In addition, with the isolation backplate 9 rising and falling synchronously with the tension mechanism, the area where the fibers form between the spinneret 8 and the tension mechanism is fully covered and isolated.

[0098] As a preferred embodiment, several fine through holes are opened on several sub-plates of the isolation back plate 9. These through holes facilitate the uniform diffusion of the low-temperature cold air formed in the spinning box 4 in front and behind the isolation back plate 9, thereby achieving the purpose of cooling and shaping the fluid.

[0099] Example 3: Based on Examples 1 and 2, a low-temperature environment needs to be formed inside the spinning box 4 so that the fine fluid coming out of the spinneret 8 can be quickly cooled and shaped to form fibers.

[0100] In this embodiment, a refrigerant is used to cool the air and circulate the air inside the spinning box 4 to exhaust the hot air inside the spinning box 4 and introduce cold air, thereby creating a low-temperature environment inside the spinning box 4.

[0101] like Figure 6 As shown, air inlet and exhaust ports are respectively opened on the sealing plates on both sides of the spinning box 4; the first end of the air inlet pipe 404 is provided on the air inlet port; the first end of the exhaust pipe 403 is provided on the exhaust port.

[0102] The second end of the intake pipe 404 and the second end of the exhaust pipe 403 are connected by a heat exchange pipeline. A refrigerant exchange box 406 and an air pump 405 are installed on the heat exchange pipeline. The heat exchange pipeline in the refrigerant exchange box 406 is arranged in a curved and coiled manner, which can increase the contact time and path between the air entering the refrigerant exchange box 406 and the refrigerant, ensuring that the air can fully achieve heat exchange. The refrigerant in the refrigerant exchange box 406 can be condensate or refrigerant. Under the action of the air pump 405, the hot air output from the exhaust pipe 403 in the spinning box 4 becomes cold air after passing through the refrigerant exchange box 406, and is then input into the spinning box 4 from the intake pipe 404, creating a low-temperature environment in the spinning box 4.

[0103] An air diffuser 407 is installed on the back panel inside the spinning box 4. The air diffuser 407 can be a fan. The air diffuser 407 is used to evenly diffuse the cold air inside the spinning box 4. This ensures that the low-temperature environment inside the spinning box 4 is uniform and consistent, so that the fluid in all positions can be adequately cooled.

[0104] Example 4: Based on Example 3, the cold air behind the isolation back plate 9 inside the spinning box 4 needs to pass through the through hole on the isolation back plate 9 to reach the front side of the isolation back plate 9, contact the fluid, cool the fluid, and cause it to solidify.

[0105] To further enhance the cooling effect, such as Figure 5 As shown, in this embodiment, condensate pipes 905 are provided on the back of several sub-plates of the isolation back plate 9; branch pipes are provided at the inlet end of the condensate pipes 905, and several branch pipes converge and connect to the main pipe; the main pipe is connected to the condensate tank, and condensate is injected into the condensate pipes 905. When the cold air in the spinning box 4 passes through the isolation back plate 9, it will come into contact with the condensate pipes 905 again to further cool the cold air, or to maintain the low temperature of the cold air, thereby improving the cooling and shaping effect on the fluid.

[0106] The condensate pipe 905 is arranged in an "S" shape, which increases the contact area between the cold air and the condensate pipe 905.

[0107] Example 5: Based on Example 1, in Example 1, the fiber exiting the tension mechanism has reached the spinning requirements. At this point, to avoid excessive secondary stretching of the fiber, its tension needs to be stabilized. In Example 1, after exiting the tension mechanism, the fiber smoothly transitions to the guide plate 6 below and then enters the winding machine 7. However, the position of the guide plate 6 is fixed, that is, the outer tangent is fixed, while the tension wheel 10 on the tension mechanism may be adjusted. Most importantly, in actual processing workshops, the spinning box 4 is usually upstairs, while the guide plate 6 and the winding machine 7 are downstairs, and there is a certain distance between the two. Therefore, after reaching the guide plate 6 from the tension mechanism, the constant tension previously maintained by the fiber may decrease, thereby reducing the tension when entering the winding machine 7 and affecting the tightness of the winding.

[0108] like Figure 1 as well as Figure 7 As shown, in this embodiment, a split tension disk 5 is provided between the tension mechanism and the guide disk 6, that is, below the outlet of the spinning box 4, and the split tension disk 5 can also rotate. Depending on the position of the tension wheel 10 on the tension mechanism, the split tension disk 5 can also be rotated and adjusted to make the fiber transition as smoothly as possible from the output of the tension mechanism to the split tension disk 5, maintaining constant tension and avoiding sudden changes in tension. After being guided by the split tension disk 5, the fiber enters the guide disk 6, further stabilizing the tension and ensuring the winding tension of the fiber on the winding machine 7.

[0109] like Figure 7As shown, one side of the tension distribution plate 5 is connected to one end of the shaft 502, and the other end of the shaft 502 moves through the control box and is rotatably mounted on the rotor of the motor. When the motor rotates, it drives the tension distribution plate 5 to rotate through the shaft 502. Several splitting claws 501 are evenly spaced on the front edge of the tension distribution plate 5. The number of splitting claws 501 can be consistent with the number of tension wheels 10. The splitting claws 501 are set as concave arc groove structures to ensure that the fibers are not scraped when passing through the splitting claws 501.
