Description

Technical Field

[0001] This utility model relates to the technical field of polyester-cotton fabric processing equipment, specifically an automatic packaging machine for polyester-cotton fabric. Background Technology

[0002] Polyester-cotton fabric is a blend of polyester and cotton. It is popular among consumers due to its crispness, smoothness, quick-drying properties, and durability. The market demand is high and the production output is also relatively high. Packaging is a crucial step in the production process of polyester-cotton fabric, and its efficiency and quality directly affect the production benefits of enterprises.

[0003] Traditional methods of packaging polyester-cotton fabrics mostly rely on manual labor. Manual packaging is not only labor-intensive and time-consuming, but also costly and inefficient, making it difficult to meet the needs of large-scale production. At the same time, manual packaging has a high error rate and inconsistent packaging quality, which can easily lead to problems such as loose binding and loose fabric, causing inconvenience for subsequent transportation and storage.

[0004] To address the drawbacks of manual packaging, some companies have begun using simple packaging equipment. However, existing polyester-cotton fabric packaging equipment still has many shortcomings. Some equipment cannot apply appropriate pressure to the polyester-cotton fabric during winding, resulting in loose, bulky fabric that occupies a large amount of transportation and storage space. Moreover, most of these devices lack automatic detection and adjustment functions, requiring staff to constantly monitor the packaging process, such as winding progress and fabric tension, making operation cumbersome and resulting in significant errors in the length of each roll. Therefore, a new solution is needed to address this problem. Utility Model Content

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0024] Please see Figure 1The present invention relates to an automatic packaging machine for polyester-cotton fabric, comprising a mounting frame 1. A conveying component, a cutting component, and a winding component are sequentially arranged on the upper end of the mounting frame 1. The conveying component includes a drive roller 17 and a driven roller 18. Both the drive roller 17 and the driven roller 18 are rotatably mounted on the mounting frame 1. The axes of the drive roller 17 and the driven roller 18 are parallel. A servo motor is provided at one end of the drive roller 17, and a reducer is provided at the output end of the servo motor to improve torque stability. The speed of the winding component is linked with that of the controller to ensure that the fabric is always in a taut state during the conveying process, thus avoiding wrinkles.

[0025] In this embodiment, the cutting assembly includes two sliders 19, which are slidably mounted on the mounting frame 1. The lower ends of the sliders 19 are connected to the mounting frame 1 via telescopic cylinders 20. A cutting blade 21 is provided between the two sliders 19. The cutting blade 21 is preferably a serrated blade. The cutting blade 21 is detachably connected to the sliders 19 by bolts for easy replacement after wear. The winding assembly includes two rotating shafts 10, which are rotatably mounted on the mounting frame 1.

[0026] See Figure 1 , Figure 2 , Figure 3 As shown, a winding drum 11 is provided between the two rotating shafts 10. The winding drum 11 is connected to the rotating shaft 10 by a fixing bolt 12. An infrared distance detector 23 is provided above the winding drum 11. The infrared distance detector 23 is mounted on the mounting frame 1 by a horizontal plate 22. The detection point of the infrared distance detector 23 is directly above the axis of the winding drum 11. The detection distance is the radius value corresponding to the preset fabric roll diameter. When the detection value reaches the preset value, in addition to controlling the winding to stop, an audible and visual alarm can be triggered by the controller to prompt the operator to prepare to replace the winding drum 11. A lifting plate 2 is provided on one side of the winding assembly.

[0027] See Figure 3 , Figure 4 As shown, a drive assembly is provided between the two ends of the lifting plate 2 and the mounting frame 1. The drive assembly includes two lead screws 13, and the spiral directions of the two lead screws 13 are the same. Both lead screws 13 are rotatably mounted on the mounting frame 1. The lead screws 13 are threadedly connected to the lifting plate 2. A nut seat with built-in ball bearing is provided at the connection between the lifting plate 2 and the lead screw 13 to reduce the friction of the threaded transmission and improve the lifting accuracy. A synchronization element is provided between the two lead screws 13. The synchronization element includes a transmission rod 14, which is rotatably mounted on the mounting frame 1.

[0028] In this embodiment, two bevel gears 15 facing the same direction are provided on the transmission rod 14, and bevel gears 16 are installed at the lower ends of the two lead screws 13. The bevel gears 15 and 16 mesh and drive each other. A stepper motor is provided at one end of the transmission rod 14. The speed of the stepper motor can be adjusted by the controller to achieve dynamic matching between the winding speed and the conveying speed. A fixing plate 3 is provided between the lifting plate 2 and the winding assembly. Support plates 8 are provided on both sides of the fixing plate 3. The upper end of the support plate 8 is arc-shaped.

[0029] In this embodiment, a pressure sensor 29 is provided between the lower end of the support plate 8 and the lifting plate 2, and the lower end of the support plate 8 is slidably disposed with the lifting plate 2. A roller 4 is rotatably mounted on the fixed plate 3, and an elastic component is provided between the roller 4 and the lifting plate 2. The elastic component includes a vertical rod 5. One end of the vertical rod 5 is mounted on the fixed plate 3, and the other end of the vertical rod 5 is slidably disposed with the lifting plate 2. A protrusion is provided on the vertical rod 5, and a spring 6 is sleeved on the vertical rod 5 between the protrusion of the vertical rod 5 and the lifting plate 2.

[0030] In this embodiment, a pressure sensor 7 is installed between the lower end of the protrusion of the vertical rod 5 and the lifting plate 2. The controller is connected to the pressure sensor 7. A controller is installed on one side of the mounting frame 1. The controller is a programmable logic controller with high-speed data processing capability. It can simultaneously receive analog signals from the pressure sensor 7, the pressure sensor 9, and the infrared distance detector 23, and output pulse signals to control the servo motor, stepper motor, cylinder, and other actuators. The pressure value detected by the pressure sensor 7 is the actual pressure of the roller 4 on the fabric. The controller presets a pressure range. When the pressure is lower than the lower limit, the controller drives the lifting plate 2 to rise, and the compression spring 6 increases its elasticity. When the pressure is higher than the upper limit, the controller controls the lifting plate 2 to fall, reducing the elasticity, thus achieving closed-loop adjustment.

[0031] The implementation principle is as follows: conveying of polyester-cotton fabric: the controller starts the conveying component, the servo motor drives the active roller 17 to rotate, the active roller 17 cooperates with the driven roller 18 to convey the polyester-cotton fabric forward to the winding component;

[0032] One end of the polyester-cotton fabric is fixed to the take-up drum 11 of the take-up assembly. The take-up drum 11 rotates under the drive of the rotating shaft 10 and begins to take up the polyester-cotton fabric. During the take-up process, the spring 6 in the elastic component is in a compressed state, and its elastic force is transmitted to the fixed plate 3 through the vertical rod 5, so that the roller 4 on the fixed plate 3 is always in contact with the polyester-cotton fabric on the take-up drum 11 and applies pressure. At the same time, the pressure sensor 7 monitors the pressure between the protrusion of the vertical rod 5 and the lifting plate 2 in real time and transmits the pressure signal to the controller.

[0033] As the winding process continues, the diameter of the polyester-cotton fabric roll on the winding drum 11 gradually increases, and the reaction force on the drum 4 changes, causing the pressure value detected by the pressure sensor 7 to change. After receiving the signal from the pressure sensor 7, if the pressure deviates from the set value, the controller controls the drive assembly to work. The stepper motor drives the two lead screws 13 to rotate synchronously through the transmission rod 14, bevel gear 15 and bevel gear 2 16. The lead screws 13 drive the lifting plate 2 to move up and down, thereby adjusting the compression of the spring 6 and keeping the pressure of the drum 4 on the polyester-cotton fabric stable.

[0034] During the winding process, the infrared distance detector 23 above the winding drum 11 detects the distance to the polyester-cotton fabric roll in real time. When the distance reaches the preset value, the infrared distance detector 23 transmits the signal to the controller, and the controller controls the winding assembly to stop winding. After the winding assembly stops working, the controller controls the cutting assembly to work. The telescopic cylinder 20 retracts, and the slider 19 drives the cutting blade 21 to move downward to cut the polyester-cotton fabric.

[0035] When replacing the take-up drum 11, the support plates 8 on both sides of the fixing plate 3 can support the take-up drum 11, and the pressure sensor 2 9 can monitor the support force, which is convenient for the operator to operate. After the replacement is completed, the new take-up drum 11 is fixed between the two rotating shafts 10 by the fixing bolt 12, and the winding work continues.

[0036] The controller, as the control center of the entire automatic packaging machine, receives signals from components such as pressure sensor 7, pressure sensor 9, and infrared distance detector 23. According to the preset program, it coordinates and controls the operation of the conveying component, cutting component, winding component, and driving component to realize the entire process of automatic packaging of polyester-cotton fabric.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
