Description

Technical Field

[0001] This application relates to the field of plastic film processing, and in particular to a winding device. Background Technology

[0002] As a core piece of equipment in the film production process, the winding equipment in a plastic film production line is responsible for winding the continuously extruded plastic film into a finished roll in a constant tension, orderly and wrinkle-free manner.

[0003] Depending on the driving method, winding equipment is mainly divided into two types: passive winding equipment and active winding equipment. Passive winding uses a simple mechanical structure and achieves winding through friction transmission. Its significant advantages are simple equipment structure, convenient operation, and easy maintenance. However, the winding tension of this winding method is uncontrollable, which has limitations in production scenarios where high tension control precision is required. In contrast, active winding is directly driven by a motor and equipped with a tension sensor and control system, enabling precise adjustment and control of winding tension to meet the production requirements of high-quality films. However, this method has a more complex equipment structure, a larger number of sensors, and a corresponding increase in potential failure points, making operation more difficult. In addition, active winding requires machine shutdown when changing rolls, resulting in low roll-changing efficiency and potentially affecting production efficiency.

[0004] In production practice, for film products with different materials, thicknesses, and performance requirements, the production process selects the appropriate winding mode based on product characteristics and winding difficulty. At the same time, considering various unforeseen circumstances that may arise during production, ideal winding equipment should have the ability to quickly switch operating modes to ensure production continuity and flexibility.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this application is to provide a winding device that can combine active and passive winding methods and quickly switch between winding methods, thereby improving winding quality and increasing the production efficiency of film materials.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] This application provides a winding device, which includes a frame, a traction roller assembly, an air shaft assembly, a state switching device, an air shaft translation device, and a control device. The traction roller assembly includes a traction roller rotatably connected to the frame and a traction drive mechanism driven by the traction roller. The air shaft assembly includes a base mechanism slidably connected to the frame, an air shaft rotatably connected to the base mechanism, and an air shaft drive mechanism driven by the air shaft. The air shaft drive mechanism is slidably connected to the base mechanism. The state switching device includes a first switching mechanism and a second switching mechanism. A portion of the first switching mechanism is fixed to the base mechanism, and another portion of the first switching mechanism is fixed to the air shaft drive mechanism. A portion of the second switching mechanism is fixed to the frame, and another portion of the second switching mechanism is fixed to the base mechanism. At least a portion of the air shaft translation device is fixed to the frame, and the air shaft translation device is also driven by the air shaft assembly. The control device is fixed to the frame and is at least electrically connected to the air shaft translation device.

[0009] Furthermore, the air shaft translation device includes a translation drive assembly, a drive synchronization assembly, and a translation transmission assembly. The translation transmission assemblies are respectively arranged on both sides of the frame. The two ends of the drive synchronization assembly are respectively driven to a translation transmission assembly. The translation drive assembly is driven to a translation transmission assembly or a drive synchronization assembly. The translation transmission assembly is also driven to the base mechanism.

[0010] Furthermore, the translation drive assembly includes a translation drive member and a clutch, the translation drive member being driven to the clutch, the clutch being driven to the translation transmission assembly, and the translation transmission assembly being driven to the base mechanism.

[0011] Furthermore, the translational transmission assembly includes a transmission output component, and the base mechanism includes a transmission input component engaged with the transmission output component.

[0012] Furthermore, the translational transmission assembly includes a first transmission member and a second transmission member, which are connected in transmission. The first transmission member is also connected in transmission to the translational drive assembly and the drive synchronization assembly.

[0013] Furthermore, the control device includes a sensing mechanism and a control mechanism electrically connected to the sensing mechanism, the sensing mechanism being fixed to the frame, and the control mechanism also being electrically connected to the translation drive assembly.

[0014] Furthermore, the sensing mechanism includes a photoelectric switch mounted on the frame.

[0015] Furthermore, the base mechanism includes a first base and a second base fixedly connected to the first base, at least one of the first base and the second base being slidably connected to the frame, and the air shaft drive mechanism includes a fixed plate and an air shaft drive component fixed to the fixed plate, with the fixed plate being slidably connected to the second base.

[0016] Furthermore, the two ends of the first switching mechanism are respectively fixed to the second base and the fixing plate, and the two ends of the second switching mechanism are respectively fixed to the second base and the frame.

[0017] Furthermore, the air shaft drive mechanism includes a power output gear, and the air shaft includes a power input gear that can mesh with the power output gear.

[0018] In the winding device provided in this application, a state switching mechanism allows for convenient switching between a first state and a second state of the air shaft. The first state, as the active winding mode, provides tension and speed control for the air shaft. The second state, as the passive winding mode, can be used as a normal winding mode and also as an emergency winding mode in case of active winding failure. Through this configuration, the winding device can quickly switch between active and passive winding modes and can use passive winding during initial winding, thereby improving winding quality and increasing production efficiency.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that the ordinal numbers such as "first" and "second" mentioned herein are introduced for ease of description based on the accompanying drawings and do not imply any limitation on the order of the components. Furthermore, since some parts of the components provided in the above embodiments have the same function, this specification uses a uniform naming convention for these parts.

[0029] This application provides a winding device 100, such as... Figure 1As shown, the winding equipment 100 includes a frame 11, a traction roller assembly 12, an air shaft assembly 13, a state switching device 14, an air shaft translation device 15, and a control device 16. The frame 11 is the basic structure of the winding equipment 100, used to support and fix the various functional components. The traction roller assembly 12 includes a traction roller 121 and a traction drive mechanism 122. The traction roller 121 is rotatably connected to the frame 11, and the traction drive mechanism 122 is drively connected to at least one end of the traction roller 121. The air shaft assembly 13 includes a base mechanism 131, an air shaft 132, and an air shaft drive mechanism 133. The base mechanism 131 is slidably connected to the frame 11, and the air shaft 132 is rotatably connected to the base mechanism 131. The air shaft 132 is used to fix the film roll and realize the winding of the film. The air shaft drive mechanism 133 is slidably connected to the base mechanism 131 and drively connected to the air shaft 132. The state switching device 14 is used to switch the state of the air shaft 132. The state switching device 14 includes a first switching mechanism 141 and a second switching mechanism 142. Specifically, the first switching mechanism 141 controls the relative position between the air shaft drive mechanism 133 and the base mechanism 131, and the second switching mechanism 142 controls the relative position between the base mechanism 131 and the frame 11. The air shaft translation device 15 can drive the air shaft in the air shaft device 13 to move along a predetermined trajectory to achieve film winding. The control device 16 is used to control the operation of various parts in the winding equipment 100. Specifically, the control device 16 is used to control the operation of the traction roller device 12, the air shaft device 13, the state switching device 14, and the air shaft translation device 15 in the winding equipment 100.

[0030] During the operation of the winding equipment 100, the air shaft 132 is in the first state (e.g., Figure 2 (as shown) or second state (such as) Figure 3 (As shown). In the first state, the air shaft drive mechanism 133 is connected to the air shaft 132, and the air shaft 132 is directly driven to rotate by the air shaft drive mechanism 133. The film winding is controlled by the power output of the air shaft drive mechanism 133. At the same time, the air shaft 132 is connected to the traction roller 121 (as shown). Figure 2 (Not shown in the image) Separates, and the air shaft 132 disengages from the traction roller 121, breaking its frictional contact. In the second state, the air shaft drive mechanism 133 separates from the air shaft 132, and there is no transmission connection between the air shaft drive mechanism 133 and the air shaft 132. Simultaneously, the air shaft 132 and the traction roller 121 (… Figure 3 (Not shown in the image) The air shaft 132 passively follows the rotation of the traction roller 121 through frictional force, thereby winding the film. The first state serves as the active winding mode of the winding device 100, providing tension and speed control for the air shaft 132. The second state serves as the passive winding mode of the winding device 100, featuring a simple structure and convenient roll changing.

[0031] When switching from the first state to the second state, the first switching mechanism 141 drives the air shaft drive mechanism 133 to slide to a position disconnected from the air shaft 132, thus breaking the power transmission path between the air shaft drive mechanism 133 and the air shaft 132. Simultaneously, the second switching mechanism 142 drives the base mechanism 131 to make the air shaft 132 adhere to the traction roller 121, and the air shaft 132 passively follows the traction roller 121 to rotate due to friction. When switching from the second state to the first state, the first switching mechanism 141 drives the air shaft drive mechanism 133 to slide to a position coupled with the air shaft 132, thus connecting the power transmission path between the air shaft drive mechanism 133 and the air shaft 132. Simultaneously, the second switching mechanism 142 drives the base mechanism 131 to disengage the air shaft 132 from the traction roller 121, and the air shaft 132 rotates autonomously under the drive of the air shaft drive mechanism 133. In the roll changing operation of the winding device 100, during initial winding, the air shaft 132 is in its second state, driven by the traction roller 121 to complete the initial winding. After the air shaft drive mechanism 133 is in position and the transmission connection is completed, the air shaft 132 switches to its first state, achieving roll changing without downtime. It should be noted that the above description only introduces one specific usage of the winding device. Based on the structure of the winding device in this embodiment and the interaction between its components, combined with the above specific usage, those skilled in the art can use and apply the winding device in this embodiment within a reasonable scope.

[0032] With the above settings, the winding device 100 can quickly switch between active winding mode and passive winding mode, and can use passive winding during the initial winding, thereby improving winding quality and increasing production efficiency.

[0033] As a specific implementation, the first switching mechanism 141 and the second switching mechanism 142 can be selected as switching mechanisms composed of cylinders and piston rods, etc., in which case the first switching mechanism 141 and the second switching mechanism 142 can achieve active adjustment.

[0034] As an optional implementation method, such as Figure 1 , Figure 2 and Figure 3As shown, the base mechanism 131 includes a first base 1311 and a second base 1312, which are fixedly connected to the first base 1311. The second base 1312 provides an installation position and support for the state switching device 14. At least one of the first base 1311 and the second base 1312 is slidably connected to the frame 11, allowing the base mechanism 131 to slide relative to the frame 11, thereby enabling the air shaft 132 to switch between a first state and a second state. The air shaft drive mechanism 133 includes a fixed plate 1331 and an air shaft drive component 1332. The fixed plate 1331 is slidably connected to the second base 1312, and the air shaft drive component 1332 is fixed to the fixed plate 1331. The fixed plate 1331 can move smoothly within its sliding stroke, thereby driving the air shaft drive component 1332 to move smoothly. The air shaft drive component 1332 can provide adjustable torque to the air shaft 132, driving it to rotate to achieve active winding and tension control.

[0035] One end of the first switching mechanism 141 is fixed to the second base 1312, and the other end is fixed to the fixed plate 1331. When the first switching mechanism 141 pushes the fixed plate 1331, it can drive the air shaft drive 1332 to move, causing the air shaft drive 1332 to engage or disengage from the air shaft 132. One end of the second switching mechanism 142 is fixed to the second base 1312, and the other end is fixed to the frame 11. When the second switching mechanism 142 pushes the second base 1312, it can move the second base 1312, thereby causing the air shaft 132 to engage with or disengage from the traction roller 121.

[0036] As an optional implementation method, such as Figure 1 , Figure 2 and Figure 3As shown, the air shaft drive mechanism 133 includes a power output gear 1333, and the air shaft 132 includes a power input gear 1321, which meshes with the power output gear 1333. The power output gear 1333 transmits the power output from the air shaft drive mechanism 133 to the air shaft 132, and the power input gear 1321 receives the power from the power output gear 1333 and applies the power to the air shaft 132, thereby rotating the air shaft 132. In the first state, the power output gear 1333 meshes with the power input gear 1321, allowing the power output from the air shaft drive mechanism 133 to be transmitted to the air shaft 132, causing the air shaft 132 to rotate, thus achieving the winding of the film. In the second state, the power output gear 1333 disengages from the power input gear 1321, and the power of the air shaft drive mechanism 133 is no longer transmitted to the air shaft 132. Simultaneously, since the air shaft 132 is in contact with the traction roller 121, it passively follows the rotation of the traction roller 121. Through the above configuration, the first switching mechanism 141 can drive the power output gear 1333 to engage or disengage from the power input gear 1321, and the second switching mechanism 142 can control the air shaft 132 to engage or disengage from the traction roller 121, thereby enabling the air shaft 132 to switch between the first and second states.

[0037] As an optional implementation method, such as Figure 4 and Figure 5 As shown, the air shaft translation device 15 includes a translation drive assembly 151, a drive synchronization assembly 152, and a translation transmission assembly 153. The translation transmission assembly 153 includes at least two sets, which are respectively mounted on both sides of the frame 11. The two ends of the drive synchronization assembly 152 are respectively connected to one set of translation transmission assemblies 153. The translation drive assembly 151 is mounted on the frame 11 and is either connected to one set of translation transmission assemblies 153 or to the drive synchronization assembly 152. In this embodiment, the translation drive assembly 151 can be connected to one translation transmission assembly 153 and then synchronously drive another translation transmission assembly 153 via the drive synchronization assembly 152 connected to the translation transmission assembly 153; alternatively, the translation drive assembly 151 can be connected to the drive synchronization assembly 152 and then synchronously drive the translation transmission assemblies 153 located at both ends via the drive synchronization assembly 152. The translation transmission assembly 153 is also connected to the base mechanism 131. The translation transmission assembly 153 is used to convert the power output from the translation drive assembly 151 and transmit it to the base mechanism 131, driving the base mechanism 131 to move smoothly in a straight line, thereby driving the air shaft 132 to move smoothly in a straight line.

[0038] As an optional implementation, the translation drive assembly 151 includes a translation drive component 1511 and a clutch 1512. The translation drive component 1511 is driveably connected to the clutch 1512. The output shaft of the translation drive component 1511 is directly connected to the input end of the clutch 1512. The output end of the clutch 1512 is driveably connected to a translation transmission assembly 153, which is driveably connected to the second base 1312. The clutch 1512 transmits power to the translation transmission assembly 153, which in turn drives the second base 1312 to perform translational sliding. The clutch 1512 can control the power output by the translation drive component 1511, providing translational driving force when the second base 1312 needs to translate.

[0039] As an optional implementation method, such as Figure 4 and Figure 5 As shown, the translational transmission assembly 153 includes a transmission output component 1531, and the second base 1312 in the base mechanism 131 includes a transmission input component 1313 meshing with the transmission output component 1531. The transmission output component 1531 outputs the power of the translational transmission assembly 153 and transmits the power to the transmission input component 1313. The transmission input component 1313 transmits the power output by the transmission output component 1531 to the second base 1312 and converts it into a linear thrust along the guide rail direction. The two ends of the air shaft 132 are respectively connected to the base mechanism 131 located on both sides of the frame 11, and the air shaft 132 moves smoothly under the drive of the base mechanism 131. Through the above arrangement, the horizontal movement of the air shaft 132 along the guide rail direction is realized. At the same time, the translational transmission assembly 153 and the base mechanism 131 are driven by the meshing transmission between gears and racks, so that the translational movement of the air shaft 132 is smooth and has high precision. Specifically, the transmission output component 1531 can be a transmission gear, and the transmission input component 1313 can be a transmission rack disposed on the second base 1312. The transmission gear and the transmission rack mesh with each other to achieve efficient and precise transmission between the translation and rotation component 153 and the base mechanism 131.

[0040] As an optional implementation method, such as Figure 4 and Figure 5As shown, the translational transmission assembly 153 includes a first transmission member 1532 and a second transmission member 1533. The first transmission member 1532 and the second transmission member 1533 are connected by a transmission link. The input end of the first transmission member 1532 is connected to the translational drive assembly 151, and the output end of the first transmission member 1532 is also connected to the drive synchronization assembly 152. The translational drive assembly 151 drives the first transmission member 1532 to rotate, and the first transmission member 1532 simultaneously drives the second transmission member 1533 and the drive synchronization assembly 152. When the clutch 1512 is engaged, the second transmission members 1533 at both ends of the drive synchronization assembly 152 rotate simultaneously, and the second transmission members 1533 drive the base mechanism 131 to move. When the clutch 1512 is disengaged, the first transmission member 1532 is not driven, and the drive synchronization assembly 152 is also not driven.

[0041] As an optional implementation, the first transmission component 1532 and the second transmission component 1533 can be connected by a synchronous belt. Synchronous belts have a certain degree of elasticity and can absorb vibration and impact. Connecting them with a synchronous belt can reduce noise and vibration during the transmission process between the first transmission component 1532 and the second transmission component 1533, thus lowering operating noise. Furthermore, the synchronous belt connection method has relatively relaxed requirements for installation precision, tolerating minor deviations and reducing debugging difficulty.

[0042] As an optional implementation, the first transmission component 1532 and the second transmission component 1533 can also be connected by gear meshing. Gear meshing transmission has advantages such as high rigidity, stable transmission ratio, and high positioning accuracy, with no risk of slippage, and can withstand greater torque and radial loads. Gear transmission has the characteristics of compact structure, small footprint, reliable performance in harsh environments such as high temperature and high dust, and a longer service life. In addition, other transmission methods such as chain drive can also be used between the first transmission component 1532 and the second transmission component 1533.

[0043] As an optional implementation method, such as Figure 6 and Figure 7 As shown, the control device 16 includes a sensing mechanism 161 and a control mechanism 162. The control mechanism 162 is electrically connected to the sensing mechanism 161 and the translation drive assembly 151. The sensing mechanism 161 is fixed on the frame 11 and is used to acquire the winding status of the air shaft 132. The sensing mechanism 161 monitors the change in the diameter of the film roll on the air shaft 132 in real time and acquires its real-time data. With this data, the translation of the air shaft 132 can be precisely controlled during winding. The control mechanism 162 receives the data fed back by the sensing mechanism 161 and outputs a control signal to adjust the action of the translation drive assembly 151, thereby achieving precise control of the translation of the air shaft 132 during active winding.

[0044] As an optional implementation, the sensing mechanism 161 can be a photoelectric switch mounted on the frame 11. When the air shaft 132 begins to wind up, the clutch 1512 is engaged. At this time, the photoelectric switch is not blocked in the middle, and it does not send a signal to the control mechanism 162. As the air shaft 132 winds up, the diameter of the film roll increases. When the photoelectric switch is blocked by the film material, it sends a signal to the control mechanism 162. The control mechanism 162 then controls the translation drive component 151 in the air shaft translation device 15 to drive the air shaft 132 to move until the photoelectric switch is no longer blocked. The photoelectric switch design makes the sensing mechanism 161 simple in structure, fast in response, and strong in anti-interference ability, enabling it to work stably in high-speed production environments.

[0045] As an alternative implementation, the sensing mechanism 161 can also be a visual recognition mechanism. For example, cameras can be mounted above and to the side of the production line to capture real-time images of the roll, and algorithms can be used to calculate the diameter of the film material or the position of the outermost film material. The visual recognition mechanism can accurately identify the diameter of the air shaft 132 or the position of the outermost film material, thereby controlling the operation of the air shaft translation device 15. Alternatively, the sensing mechanism 161 can also be an ultrasonic sensing mechanism, using ultrasonic waves to monitor the diameter of the film roll or the position of the outermost film material on the air shaft 132 in real time.

[0046] Finally, it should be noted that the above are only some preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
