Description

Technical Field

[0001] The invention relates to the technical field of polyester fiber production, and in particular to a polyester fiber multifunctional modified production line and a production method thereof. Background Art

[0002] During the processing of polyester fibers, through stretching, the fiber molecular chains will be oriented along the stretching direction, thereby improving the strength and elasticity of the fibers. The stretching modification mainly utilizes the plastic deformation and orientation effect of polyester fibers to enhance the fiber's resistance to deformation and fracture when subjected to external forces. However, when modifying the polyester fibers processed into linear shapes, the entire roll of polyester fibers cannot be stretched uniformly during the stretching modification, resulting in the unbalanced crack and deformation resistance of the polyester fibers after stretching modification.

[0032] In the present invention, the power mechanism is set up, and the first screw can be driven to rotate by starting the driving motor. At this time, the nut can be moved downward under the thread transmission action of the corresponding nut, and when the first screw rotates, the second screw can be driven to rotate synchronously under the transmission action of the two first synchronous wheels and the first synchronous belt, so that the two nuts can be moved downward synchronously, thereby driving the limit assembly to move, and the transmission of the limit assembly can drive the moving frame to move downward;

[0033] In the present invention, by setting the tension detection mechanism, after the polyester fiber line is clamped, when the polyester fiber line is subjected to the tension of the transmission mechanism, the support frame and the moving frame can be driven to move, and when the moving frame is moving, the pressing component can be driven to approach the connecting plate, and after the pressing component contacts the connecting plate, the limit cover can use the pressing component to press the pressure sensor as the moving frame continues to move, and after the pressure sensor is subjected to pressure, the pressure value can be converted into a digital value and transmitted to the display screen, so that the tension value of multiple polyester fiber lines can be controlled, so that when the polyester fiber lines are subjected to stretching modification, the polyester fiber lines can be prevented from being broken;

[0034] In the present invention, through the transmission mechanism, after a plurality of polyester fiber lines are sequentially laid on the first transmission roller and the second transmission roller, the material blocking assembly is started to press the plurality of polyester fiber lines against the first transmission roller and the second transmission roller respectively in close contact, and then the servo motor is started to drive the first transmission roller to rotate, and then the second transmission roller can be driven to rotate simultaneously under the transmission cooperation of the two second synchronous wheels and the second synchronous belt, thereby realizing the transportation of a plurality of polyester fiber lines, and realizing the sequential stretching of different areas of the polyester fiber lines, which is convenient for the comprehensive stretching modification of the polyester fiber lines.

DETAILED DESCRIPTION

[0045] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0047] Example 1: Reference Figure 1-Figure 7 In this embodiment, a polyester fiber multifunctional modification production line is provided. The base 1 is used as the supporting structure of the entire production line, and two supporting rails 2 are symmetrically fixedly installed on one side of the top. A supporting plate 3 is slidably connected to the two supporting rails 2 for installing a subsequent clamping mechanism.

[0048] Next, we design the clamping mechanism in detail. Figure 2 and Figure 3As shown, the clamping mechanism is mainly composed of a support frame 4, a clamp 5, a mobile frame 6 and a positioning clamp 7. The support frame 4 is fixedly installed on the top of the support plate 3, and a plurality of clamps 5 are fixedly installed at equal intervals on the inner wall of the bottom thereof. The polyester fiber lines need to pass through these clamps 5. On the support frame 4, we slidably connect a mobile frame 6, and a plurality of positioning clamps 7 are fixedly installed at equal intervals on the inner wall of the top thereof. These positioning clamps 7 cooperate with the corresponding clamps 5. When the mobile frame 6 moves downward, the positioning clamps 7 will push the clamps 5 to contract, thereby clamping the polyester fiber lines.

[0049] In order to realize the up and down movement of the mobile frame 6, we designed a power mechanism. Figure 2 As shown, the power mechanism is mainly composed of a driving motor 14, a first screw 15, a second screw 16, a nut 17, a first synchronous wheel 18 and a first synchronous belt 19. The driving motor 14 is fixedly mounted on the top of the base 1, and the first screw 15 is fixedly mounted on its output shaft. The second screw 16 is rotatably connected to the top of the base 1 and is arranged parallel to the first screw 15. A nut 17 is threadedly connected to each of the two screws. In order to drive the two nuts 17 to move synchronously, we fixedly installed a first synchronous wheel 18 on the top of the first screw 15 and the second screw 16, respectively, and a first synchronous belt 19 is provided on the two first synchronous wheels 18 for transmission.

[0050] Next, we design a limit assembly to transmit power to the moving frame 6. Figure 2 and Figure 3 As shown, the limiting assembly is mainly composed of a first limiting column 12, a U-shaped plate 11, a connecting plate 10, a slide rail 9, a slide plate 8 and a second limiting column 13. Two first limiting columns 12 are symmetrically fixedly installed on the top of the base 1, and the U-shaped plate 11 is slidably connected to the first limiting columns 12. A connecting plate 10 is fixedly installed on one side of the two U-shaped plates 11, and two slide rails 9 are symmetrically fixedly installed on one side of the connecting plate 10. A slide plate 8 is slidably connected to the slide rail 9, and the two slide rails 8 are respectively fixedly connected to the two sides of the movable frame 6. Two nuts 17 are respectively fixedly connected to the corresponding slide rails 9. In addition, we symmetrically fixedly installed two second limiting columns 13 on the top of the base 1, and the second limiting columns 13 are slidably connected to the corresponding slide rails 9 to ensure that the slide rails 9 can only move longitudinally.

[0051] Finally, we design a tension detection mechanism and a transmission mechanism. The tension detection mechanism can be installed on the connecting plate 10, and cooperate with the mobile frame 6 or the positioning clamping plate 7 to detect the tension on the polyester fiber line. The transmission mechanism is installed on the other side of the top of the base 1 to transport the polyester fiber line.

[0052] In actual operation, we first pass the polyester fiber line through the corresponding clamp 5. Then start the drive motor 14 to drive the first screw 15 to rotate. Since the first screw 15 and the second screw 16 are driven by the first synchronous wheel 18 and the first synchronous belt 19, the two nuts 17 will move downward synchronously. The movement of the nut 17 will drive the slide rail 9 and the slide plate 8 to move downward, and then drive the mobile frame 6 to move downward. The movement of the mobile frame 6 will make the positioning clamp 7 cooperate with the corresponding clamp 5, so that the clamp 5 will shrink and clamp the polyester fiber line. At this time, the transmission mechanism starts to work and transports the polyester fiber line. During the transportation process, the polyester fiber line will be subjected to tension, and the tension detection mechanism will detect and record the tension data in real time.

[0053] Next, we design the tension detection mechanism in detail. Figure 6 and Figure 7 As shown, the tension detection mechanism mainly includes a fixed plate 30 fixedly mounted on one side of the top of the mobile frame 6. A limit cover 31 is fixedly mounted on one side of the fixed plate 30, and a pressure sensor 35 is installed in the limit cover 31 for detecting the pressure value. A display screen 36 is fixedly mounted on the other side of the fixed plate 30, and the display screen 36 is electrically connected to the pressure sensor 35 for displaying the pressure value.

[0054] In the limiting cover 31, we installed a pressing component for pressing the pressure sensor 35. Figure 6 As shown, the pressing assembly includes a pressure plate 32 slidably connected in the limit cover 31, a pressure rod 33 is fixedly installed on one side of the pressure plate 32, and one end of the pressure rod 33 extends to the outside of the limit cover 31 and is fixedly installed with a force plate 34. The force plate 34 is in contact with the connecting plate 10. When the moving frame 6 drives the limit cover 31 to move, the force plate 34 will first contact the connecting plate 10. Afterwards, as the limit cover 31 continues to move, the pressure plate 32 will press the pressure sensor 35, convert the pressure value into a digital value and transmit it to the display screen 36. In this way, we can monitor the tension value of the polyester fiber line in real time to ensure that it will not be broken during the stretching modification process.

[0055] In addition, we also designed a transmission mechanism for conveying polyester fiber lines. The transmission mechanism mainly includes two mounting plates 20 symmetrically fixedly mounted on the other side of the top of the base 1. The two mounting plates 20 are rotatably connected to the same first transmission roller 21 and the same second transmission roller 22. The first transmission roller 21 is located on one side of the second transmission roller 22, and a certain distance is maintained between the two transmission rollers so that the polyester fiber lines can pass smoothly.

[0056] like Figure 4As shown, a servo motor 23 is fixedly mounted on the mounting plate 20 on one side, and the output shaft of the servo motor 23 is fixedly connected to the first transmission roller 21. One end of the first transmission roller 21 and one end of the second transmission roller 22 both pass through the mounting plate 20 on the other side, and are fixedly mounted with a second synchronous wheel 24. The same second synchronous belt 25 is driven and sleeved on the two second synchronous wheels 24 to achieve synchronous rotation of the two transmission rollers.

[0057] Example 2: Reference Figure 4 and Figure 5 This embodiment is based on the embodiment one. Regarding the polyester fiber multifunctional modified production line proposed in the embodiment one, in order to ensure that the polyester fiber lines can be in close contact with the transmission roller, we installed a material blocking assembly on the top of the two mounting plates 20. The material blocking assembly includes a limit frame 26, and the limit frame 26 is fixedly connected to the top of the two mounting plates 20 respectively. A transmission frame 28 is slidably connected in the limit frame 26, and a pressure roller 29 is rotatably connected in the transmission frame 28. Two electric push rods 27 are symmetrically fixedly installed on the top of the limit frame 26, and the output shaft of the electric push rod 27 extends into the limit frame 26 and is fixedly connected to the top of the transmission frame 28. By starting the two electric push rods 27, we can drive the transmission frame 28 to move downward, and then drive the pressure roller 29 to press the polyester fiber lines so that they are in close contact with the transmission roller.

[0058] In actual operation, we first put a plurality of polyester fiber lines on the first transmission roller 21 and the second transmission roller 22 in sequence, and start the material blocking assembly to make the pressing roller 29 press the polyester fiber lines. Then, we start the servo motor 23 to drive the first transmission roller 21 to rotate. Under the transmission cooperation of the two second synchronous wheels 24 and the second synchronous belt 25, the second transmission roller 22 will also rotate at the same time, thereby realizing the conveying of the polyester fiber lines.

[0059] During the conveying process, we pass the polyester fiber line through the clamp 5 of the clamping mechanism, and start the power mechanism to drive the moving frame 6 to move downward. The movement of the moving frame 6 drives the force plate 34 of the pressing assembly to contact the connecting plate 10, and continues to move to press the pressure sensor 35. The pressure sensor 35 converts the detected pressure value into a number and displays it on the display screen 36. We can control the tension value of the polyester fiber line according to the value on the display screen 36 to ensure that it will not be broken during the stretching modification process.

[0060] The present invention provides a production method, which is applied to the above-mentioned multifunctional modified polyester fiber production line, comprising the following steps:

[0061] S1, passing the polyester fiber line through the corresponding clamp 5, and then sequentially placing multiple polyester fiber lines on the first transmission roller 21 and the second transmission roller 22;

[0062] S2, starting the two electric push rods 27 to drive the transmission frame 28 to move downward, thereby driving the pressing roller 29 to move downward, and using the pressing roller 29 to press the multiple polyester fiber lines, so that the multiple polyester fiber lines are in close contact with the first transmission roller 21 and the second transmission roller 22 respectively;

[0063] S3, start the servo motor 23 to drive the first transmission roller 21 to rotate, and then drive the second transmission roller 22 to rotate simultaneously under the transmission cooperation of the two second synchronous wheels 24 and the second synchronous belt 25, so as to realize the conveying of multiple polyester fiber lines;

[0064] S4. When it is necessary to stretch and modify a plurality of polyester fiber lines, the first screw 15 can be driven to rotate by starting the driving motor 14. At this time, the nut 17 can be moved downward under the thread transmission action of the corresponding nut 17, and when the first screw 15 rotates, the second screw 16 can be driven to rotate synchronously under the transmission action of the two first synchronous wheels 18 and the first synchronous belt 19, so that the two nuts 17 can be moved downward synchronously. When the nut 17 moves downward, the slide rail 9 can be driven to move. At this time, under the transmission action of the slide plate 8, the mobile frame 6 can be driven to move downward, and at this time, the plurality of positioning clamps 7 can be driven to move downward, so that the positioning clamps 7 cooperate with the corresponding clamps 5, so that the clamps 5 can be contracted, and the clamps 5 can clamp the polyester fiber lines after contraction;

[0065] S5. After the plurality of polyester fiber lines are driven by the first transmission roller 21 and the second transmission roller 22, they can continue to move, and can drive the support frame 4 and the moving frame 6 to move. When the moving frame 6 moves, it can drive the force plate 34 to approach the connecting plate 10. After the force plate 34 contacts the connecting plate 10, when the limit cover 31 moves laterally with the moving frame 6, the pressure plate 32 will not move with the limit cover 31 until the pressure plate 32 exerts pressure on the pressure sensor 35, so that the pressure sensor 35 is in a stressed state. After the pressure sensor 35 is subjected to pressure, the pressure value can be converted into a digital value and transmitted to the display screen 36, so that the tension value of the plurality of polyester fiber lines can be controlled, so that when the polyester fiber lines are stretched and modified, the polyester fiber lines can be prevented from being broken;

[0066] S6. After stretching and modifying a section of polyester fiber lines, the drive motor 14 can be started to run in reverse, driving the multiple positioning clamps 7 to reset upward, so that the multiple clamps 5 release the clamping of the polyester fiber lines. At this time, the multiple polyester fiber lines can be transported so as to stretch and modify the subsequent polyester fiber lines.

[0067] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 14, servo motor 23, electric push rod 27, pressure sensor 35 and display screen 36 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0068] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
