Description

Technical Field

[0001] This utility model relates to a knitted fabric winding device, particularly a polyester knitted fabric winding device. Background Technology

[0002] After the knitted fabric is produced, it needs to be wound up using a winding device for convenient storage and transportation. A typical winding device mainly includes a guide roller, a winding shaft, and a winding motor. To ensure the winding effect and uniformity, a correction device is usually connected to the winding shaft to assist in the winding process. For example, the patent document with patent number "CN202022166335.4" discloses a device that uses two limit plates that slide on the winding roller to correct the deviation by adjusting their positions. However, in actual use, this correction device has several drawbacks. First, because the connection between the limit ring and the winding roller is very tight and is fixed by abutment bolts, when the limit ring needs to be moved, the abutment bolts must be loosened manually before adjustment can be made, resulting in low overall correction efficiency. Furthermore, the limit rings require manual removal during the subsequent unloading process, making unloading more complicated. Therefore, existing knitted fabric winding devices that use limit rings for winding and correction have problems such as low correction efficiency and inconvenience in unloading materials. Utility Model Content

[0003] The purpose of this invention is to provide a winding device for polyester knitted fabric. This invention not only improves the efficiency of the correction process but also has the advantage of convenient material unloading.

[0004] The technical solution of this utility model: A polyester knitted fabric winding device, comprising a base, a guide roller, a winding roller, a winding motor, and a controller disposed on the side of the base. Two symmetrically arranged vertical mounting plates are disposed between the guide roller and the winding roller, and multiple staggered guide rollers are disposed between the two vertical mounting plates. A first adjustment device is disposed on the top surface of the base, and a correction and translation seat is disposed on the first adjustment device. The winding roller and the winding motor are both disposed on the correction and translation seat. A correction detection seat is disposed on the top surface of each vertical mounting plate, located between the guide roller and the first adjustment device, and a correction detection seat is disposed on the bottom surface of each correction detection seat. Equipped with CCD cameras; both the first adjustment device and the CCD cameras are electrically connected to the controller; the two CCD cameras can capture the real-time position of both sides of the knitted fabric, and the controller judges the position based on the signals sent by the CCD cameras. If a deviation occurs, the controller controls the first adjustment device to drive the take-up roller and the take-up motor to move horizontally. This not only achieves the purpose of correction, but also completes the take-up work simultaneously. Compared with the previous use of correction rollers or setting retaining rings on both sides of the take-up roller to achieve the purpose of correction, the overall efficiency of correction work is improved, and the subsequent material cutting work is facilitated.

[0005] In the aforementioned polyester knitted fabric winding device, the first adjustment device includes a first servo motor, on which a first ball screw is connected; a first nut seat is slidably mounted on the first ball screw, and first slide rails are provided on both sides of the first ball screw; the correction and translation seat is fixedly mounted on the top surface of the first nut seat, and a first slide groove that cooperates with the first slide rail is provided on the bottom surface of the correction and translation seat; the first slide rails can guide and support the movement of the correction and translation seat, enabling the correction and translation seat to perform stable translation and sliding, thus ensuring the stability of the structure.

[0006] In the aforementioned polyester knitted fabric winding device, limit blocks are installed at both ends of the first slide rail, and a pressure sensor is provided on the side of each limit block facing the other limit block; the pressure sensor is electrically connected to the controller; by using multiple limit blocks, the two ends of the moving path of the correction and translation seat can be limited and blocked, avoiding over-movement and ensuring the stability of operation; moreover, the setting of the pressure sensor can realize the use of electrical signals to facilitate the controller to control the first adjustment device to stop in time, thereby reducing the collision time between the correction and translation seat and the limit blocks, minimizing the wear between the correction and translation seat and the limit blocks, and extending the service life.

[0007] In the aforementioned polyester knitted fabric winding device, a first tension roller is installed on the two vertical mounting plates at a position corresponding to the guide roller and the guide roller; a second tension roller is installed on the side of the first tension roller away from the guide roller, and a second adjustment device is connected to both ends of the second tension roller, which is installed on the vertical mounting plate; a laser displacement sensor is installed between the first tension roller and the second tension roller, located in the middle of the top surface of the base; both the laser displacement sensor and the second adjustment device are electrically connected to the controller; the distance between the fabric and the base can be monitored in real time using the laser displacement sensor, and the fluctuation of the fabric can be determined based on the distance between the fabric and the base, thereby obtaining the tension value of the fabric. Finally, the controller controls the start and stop of the second adjustment device based on the obtained tension value, thereby completing the purpose of adjusting the tension value of the fabric through the second tension roller, making the overall detection and installation more flexible.

[0008] In the aforementioned polyester knitted fabric winding device, the second adjustment device includes a second ball screw disposed on the side of the vertical mounting plate away from the other vertical mounting plate, the end of the second ball screw being connected to a second servo motor; a second nut seat is slidably mounted on the second ball screw; a connecting seat is fixedly mounted on the side of the top surface of the second nut seat facing the vertical mounting plate, and the connecting seat is provided with a through hole for mounting a second tension roller.

[0009] In the aforementioned polyester knitted fabric winding device, a waist-shaped through groove is provided on the vertical mounting plate at the position corresponding to the connecting seat, and two symmetrically arranged baffles are installed on the inner side wall of the waist-shaped through groove; two symmetrically distributed strip grooves are provided on the side of the connecting seat, and the strip grooves cooperate with the baffles; by providing a waist-shaped through groove on the vertical mounting plate, and providing baffles on the inner side wall of the waist-shaped through groove, in conjunction with the strip groove on the connecting seat, the connecting seat can slide stably up and down on the vertical mounting plate, ensuring the stability of the structure.

[0010] In the aforementioned polyester knitted fabric winding device, a drying mounting base is installed between the top surfaces of two vertical mounting plates at a position directly above all the guide rollers. Multiple evenly distributed hot air pipes are provided on the bottom surface of the drying mounting base, and multiple evenly distributed hot air outlets are provided on the bottom surface of each hot air pipe. A main air duct is installed between the ends of all the hot air pipes, and a hot air fan is connected to the end of the main air duct. Hot air can be blown onto the surface of the knitted fabric using the hot air pipes, thereby removing the moisture from the surface of the knitted fabric and preventing internal mold growth after the knitted fabric with moisture is wound up, thus ensuring the quality of the winding.

[0011] Compared with existing technologies, this utility model improves the existing knitted fabric winding device. By setting a first adjustment device, a correction and translation seat, two CCD cameras, and a controller on the base, the two CCD cameras can capture the real-time position of both sides of the knitted fabric and send the captured signals to the controller. The controller then judges the deviation based on the signals sent by the CCD cameras. If a deviation occurs, it controls the first adjustment device to start, so that the first adjustment device drives the winding roller and winding motor to move through the correction and translation seat. This not only achieves the purpose of correction but also completes the winding work simultaneously. Compared with the previous method of using a correction roller or setting baffles on both sides of the winding roller to achieve the purpose of correction, the overall efficiency of correction is improved, and the subsequent feeding work is facilitated. At the same time, by setting multiple staggered guide rollers, the movement path of the knitted fabric can be extended, so that the subsequent winding speed can be better matched with the feeding speed of the guide roller, ensuring the winding effect.

[0012] Furthermore, this utility model also features first slide rails on both sides of the first ball screw, and a first sliding groove on the bottom surface of the correction and translation seat that matches the first slide rails. The first slide rails guide and support the movement of the correction and translation seat, enabling stable translation and sliding and ensuring structural stability. Limit blocks are provided at both ends of the first slide rails, each equipped with a pressure sensor. These limit blocks limit and block the movement of the correction and translation seat at both ends, preventing over-movement and ensuring operational stability. The pressure sensors allow for timely stopping of the first adjustment device via electrical signals, reducing the collision time between the correction and translation seat and the limit blocks, minimizing wear and extending service life. Finally, a first tension roller and a second tension roller are installed between the two vertical mounting plates, with the second tension roller sliding via a second adjustment device. Mounted between two vertical mounting plates, and equipped with a laser displacement sensor located on the top surface of the base, the distance between the fabric and the base is monitored in real time. The fabric fluctuation is determined based on this distance, leading to the fabric tension value. Finally, the controller activates and deactivates the second adjustment device based on the obtained tension value, thus adjusting the fabric tension value via the second tension roller. This makes the overall detection and installation more flexible. A waist-shaped groove with a stop on its inner wall, combined with a strip groove on the connecting seat, allows the connecting seat to slide stably up and down on the vertical mounting plate, ensuring structural stability. A drying mounting seat with multiple hot air pipes is located above all the guide rollers. These pipes blow hot air onto the surface of the knitted fabric, removing moisture and preventing internal mold growth after winding, thus ensuring the quality of the winding process. Therefore, this utility model not only improves the efficiency of deviation correction work, but also has the advantages of convenient material feeding, good winding effect, high working stability, long service life, high installation flexibility and high winding quality.

[0020] Working Principle: During the winding process, the entire device is first placed on a horizontal surface, and the guide roller 2 is connected to the output section of the previous knitted fabric production process. Then, the entire device is connected to an external safe mains power supply, energizing the controller 5, CCD camera 10, pressure sensor 16, and laser displacement sensor 19. (The controller 5 used in this application can specifically be an FPGA controller, Cortex-R8, or Cortex-M7 programmable controller; the pressure sensor 16 can specifically be a PX309-200A5V, PXM600MU-350BARGV, or PXM600MU-70BARGV model; the laser displacement sensor 19...) Specifically, models such as LD620-5, LDI-G19-100-A210S, or LDI-G19-075-A220S can be used. Then, one end of the knitted fabric to be wound is sequentially passed through guide roller 2, first tension roller 17, second tension roller 18, and guide roller 7, and initially wound onto take-up roller 3. Then, the take-up motor 4 is started manually via controller 5 for a certain period. After start-up, the take-up motor 4 drives the take-up roller 3 to rotate. The direction of rotation of the take-up roller 3 is opposite to the direction in which the knitted fabric is initially wound onto the take-up roller 3, thus enabling the take-up roller 3 to wind up the knitted fabric. Throughout the entire winding process, the CCD cameras 10 located directly above both sides of the knitted fabric will monitor the knitted fabric in real time. The side of the fabric is captured and detected (CCD camera 10 is set at a distance of 10 to 15 mm from the fabric surface), and the captured optical signal is converted into an analog current signal. The current signal is amplified and converted from analog to digital to obtain an image signal, which is then sent to controller 5 through a data transmission line. Controller 5 judges whether there is a positional deviation based on the image signal. If there is a large deviation to the left, controller 5 will control the first servo motor 11 to start forward. After the first servo motor 11 starts forward, it will drive the first ball screw 12 to rotate. After the first ball screw 12 rotates, it will drive the first nut seat to translate to the right. During the translation of the first nut seat to the right, it will drive the correction translation seat 8 to translate to the right as well. During the process, the take-up roller 3 and the take-up motor 4 will move together, thereby applying a pulling force to the knitted fabric in the opposite direction of the deviation, so that the knitted fabric can be straightened and the correction work is completed. Similarly, if a rightward deviation occurs, the first servo motor 11 is controlled to start in reverse, so that the first ball screw 12 drives the correction translation seat 8 to move to the left, thereby applying a pulling force to the knitted fabric in the opposite direction of the deviation, so that the knitted fabric can be straightened and the correction work is completed. At the same time, during the correction process, the CCD camera 10 will still capture and detect the side of the knitted fabric in real time. When the edge deviation is between -0.1mm and 0.1mm, the controller 5 will control the first servo motor 11 to stop, completing the correction work.

[0021] Simultaneously, during the winding process, the laser displacement sensor 19, located directly below the first tension roller 17 and the second tension roller 18, detects the distance between itself and the fabric in real time. The detected numerical signal is sent to the controller 5, which stores it and calculates the tension value based on the simplified model of Hooke's Law: tension T = k * Δh (where k is the equivalent elastic stiffness coefficient of the fabric; Δh is the real-time vertical displacement detected by the laser displacement sensor 19). The controller 5 then compares this tension value with the internally set tension value to obtain the tension difference. Based on this tension difference, the controller starts the second servo motor 21. The starting of the second servo motor 21 drives the second ball screw 20 to rotate, which in turn moves the second nut seat. This movement of the second nut seat then moves the connecting seat 22, causing the two connecting seats to move together. The second tension roller 18 on 22 moves to adjust the fabric tension. During the winding process, the external hot air blower connected to the hot air pipe 27 and the controller 5 are powered on and started simultaneously. After the hot air blower starts, it delivers hot air into the hot air pipe 27. The hot air entering the hot air pipe 27 blows towards the base 1 through the hot air outlet on the bottom surface of the hot air pipe 27. When the knitted fabric passes under the hot air pipe 27, the hot air blown out by the hot air pipe 27 can remove the moisture on the surface of the knitted fabric, preventing the knitted fabric with moisture from becoming moldy after being wound up, thus ensuring the quality of the winding. After the winding is completed (i.e., after the time for controlling the start of the winding motor 4 is reached), the controller 5 will control the winding motor 4 to stop. Then the operator can remove the wound knitted fabric roll from the winding roller 3 to complete the unloading.
