Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, and in particular to a multi-roll film material synchronous feeding mechanism with real-time tension compensation. Background Technology

[0002] In modern industrial production, to improve efficiency, multiple rolls of film are often simultaneously and synchronously fed to subsequent processing stations. Precise control of the conveying tension of each roll, ensuring consistency and constancy across all rolls, is a crucial technological prerequisite for guaranteeing product quality and stable production line operation. Therefore, developing a mechanism capable of synchronous and stable feeding of multiple rolls of film, with real-time tension adjustment and compensation functions, is of great significance for enhancing the automation level and product competitiveness of related industries.

[0003] Existing multi-roll membrane feeding mechanisms typically employ simple passive tension control methods, such as using mechanical friction brakes or fixed-weight floating rollers to provide tension. These methods maintain basic tension by applying a fixed resistance or force to the axis of the membrane roll. While the structure is relatively simple, the tension it provides is static or constant, and cannot be adjusted and compensated for in real time and dynamically based on factors such as changes in membrane roll diameter, differences in winding tightness, and fluctuations in conveyor speed.

[0004] However, existing technologies have a prominent problem: due to differences in the initial state, roll diameter, and winding tightness of each roll of film, these differences directly lead to inconsistent actual tension among the rolls during synchronous feeding. This uneven tension prevents the film from maintaining a stable tension state before entering the processing stage, easily causing unstable feeding, wrinkling, or even tearing of the material surface, thus seriously affecting product quality and significantly reducing production efficiency. Therefore, a multi-roll film synchronous feeding mechanism with real-time tension compensation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-roll film material synchronous feeding mechanism with real-time tension compensation. This aims to improve upon existing technologies where feeding mechanisms often employ passive tension control, failing to provide real-time dynamic compensation based on differences in film materials. This results in uneven tension across multiple rolls of film, causing unstable feeding, wrinkling, or tearing, severely impacting product quality and production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-roll film material synchronous feeding mechanism with real-time tension compensation, including a base frame, a support frame fixedly connected to the upper surface of the base frame, and a tension adjustment mechanism installed on the upper surface of the base frame near the support frame. The tension adjustment mechanism includes a slide rail, the lower surface of which is fixedly connected to the upper surface of the base frame near the support frame. A slider is slidably connected to the outer wall of the slide rail, and a movable frame is fixedly connected to the upper surface of the slider. A limit roller is rotatably connected to the middle of the upper surface of the movable frame. A hydraulic rod is provided between the support frame and the movable frame. A connecting frame is fixedly connected to one side of the outer wall of the movable frame. A rack plate is fixedly connected to the lower surface of the connecting frame. A hinge seat is fixedly connected to one side of the outer wall of the base frame. A rotating rod is rotatably connected inside the hinge seat. A rotating rod is fixedly connected to the outer wall of the rotating rod. A gear is rotatably connected to the outer wall of the rotating rod. The gear meshes with the tooth end of the rack plate. A rotating plate is fixedly connected to the outer wall of the rotating rod. A tension roller is rotatably connected inside the rotating plate.

[0007] As a further description of the above technical solution: through the cooperation of hydraulic rod one and the moving frame, and through the linkage mechanism of rack plate and gear, the linear thrust of hydraulic rod one is converted into the position and force adjustment of tension roller; this design constitutes an active tension adjustment system, which can dynamically compensate according to the real-time changes in film tension, thereby accurately controlling and maintaining constant tension of multiple rolls of film during the feeding process, effectively solving various production problems caused by uneven tension.

[0008] Preferably, a support frame is fixedly connected to the upper surface of the bottom frame, and a V-shaped frame symmetrically connected to one side of the outer wall of the support frame is rotatably connected.

[0009] As a further description of the above technical solution: the cooperation between the support frame and the rotatable left-right symmetrical V-shaped frame provides a stable and adaptable bearing platform for multiple rolls of film, realizing convenient loading and quick replacement of rolls of different specifications, and significantly improving the ease of operation and practicality of the equipment.

[0010] Preferably, a motor is fixedly connected to the upper side of the outer wall of the support frame, and a transmission roller is fixedly connected to the output end of the motor.

[0011] As a further description of the above technical solution: the cooperation between motor one and transmission roller one provides active and stable traction power for the conveying of multiple rolls of film, realizes smooth and synchronous feeding control of film, ensures the continuity and reliability of the feeding process, and is the key structure for realizing automated feeding.

[0012] Preferably, a hydraulic rod is provided between the other side of the outer wall of the support frame and the V-shaped frame, and a winding roller is provided on the upper side of the V-shaped frame.

[0013] As a further description of the above technical solution: the cooperation between the hydraulic rod two and the V-shaped frame enables precise adjustment of the bearing angle and position of the film roll, facilitating the loading, unloading, and alignment of the roll. This design, working in conjunction with the take-up roller, enhances the control over the film winding process and improves the automation and convenience of operation.

[0014] Preferably, a second support frame is fixedly connected to the upper surface of the bottom frame, and the second support frame is disposed on one side of the tension roller.

[0015] As a further description of the above technical solution: by adding a second support frame located on one side of the tension roller, a stable mounting base is provided for the subsequent drive or auxiliary mechanisms, optimizing the overall layout of the equipment. This design ensures the rationality of the installation positions of key components and the stability of the structure, providing a guarantee for reliable synchronous conveying.

[0016] Preferably, a second motor is fixedly connected to the upper surface of the second support frame, and a second transmission roller is fixedly connected to the output end of the second motor.

[0017] As a further description of the above technical solution: by adding a second motor and a second transmission roller to form a second drive mechanism, which works in conjunction with the first drive mechanism, a more balanced traction force is provided for multiple rolls of film, effectively avoiding slippage and further enhancing the stability and reliability of synchronous feeding under long distances or high tension.

[0018] Preferably, the outer wall of the rack plate is disposed through the interior of the hinge seat, and the lower surface of the rack plate is slidably connected to the inner wall of the hinge seat.

[0019] As a further description of the above technical solution: by having the rack plate pass through and slide inside the hinge seat, precise guidance and support are provided for the reciprocating linear motion of the rack plate, ensuring the smoothness and accuracy of the meshing transmission of the gear and rack mechanism, which is an important guarantee for realizing the precise tension compensation function.

[0020] Preferably, a limiting roller is provided on the upper side of the outer wall of the support frame, and the limiting roller is arranged symmetrically on the left and right.

[0021] As a further description of the above technical solution: by setting symmetrical limiting rollers on the upper side of the support frame, the multiple rolls of film material drawn from the material roll are effectively regulated and guided, preventing the film material from deviating or wrinkling in the initial stage of conveying, and creating good conditions for subsequent precise tension control and synchronous conveying.

[0022] This utility model has the following beneficial effects: 1. In this utility model, a hydraulic rod pushes the moving frame to move, which in turn drives the rack plate on one side of the connecting frame to mesh with the gear and rotate. This causes the rotating rod to drive the tension roller inside the rotating plate and the limiting roller above the moving frame to move in opposite directions. This achieves reverse tension adjustment of the film material while ensuring that the tension of multiple rolls of film remains consistent before entering the processing stage. This solves the problems of unstable feeding, wrinkling or tearing of materials caused by inconsistent tension of each roll when feeding multiple rolls of film simultaneously. This improves the stability and reliability of feeding, ensures product quality, and significantly increases production efficiency.

[0023] 2. In this utility model, by setting up a symmetrical V-shaped frame, multiple rolls of film material of different specifications can be easily supported. Motor 1 and Motor 2 drive transmission roller 1 and Transmission Roller 2 respectively, achieving synchronous and stable conveying of multiple rolls of film material. The setting of hydraulic rod 2 and the cooperation of the take-up roller further enhance the control capability of film material unwinding and rewinding, making the entire feeding process more automated and controllable. Limiting roller 1 and Limiting roller 2 effectively guide the direction of the film material, preventing deviation. This mechanism integrates multiple functions such as stable load-bearing, real-time compensation, synchronous drive, and precise guidance, greatly simplifying operation, reducing labor intensity, and improving the overall practicality of the equipment.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0027] Reference Figure 1 - Figure 4 An embodiment of this utility model provides a multi-roll film material synchronous feeding mechanism with real-time tension compensation, including a bottom frame 1 as an integral frame, a support frame 2 for supporting and installing other components fixedly connected to the upper surface of the bottom frame 1, a limiting roller 3 for guiding the direction of the film material is provided on the upper side of the outer wall of the support frame 2, the limiting roller 3 is arranged symmetrically on the left and right to adapt to the synchronous feeding of multiple rolls of film material, and a tension adjustment mechanism for real-time adjustment of the film material tension is installed on the upper surface of the bottom frame 1 near the support frame 2. The tension adjustment mechanism includes a slide rail 4 for providing a linear motion path. The lower surface of the slide rail 4 is fixedly connected to the upper surface of the base frame 1 near the support frame 2. A slider 5, which can move along the slide rail 4, is slidably connected to the outer wall of the slide rail 4. A movable frame 6 for carrying the tensioning assembly is fixedly connected to the upper surface of the slider 5. A limiting roller 14 for re-guiding the membrane material is rotatably connected to the middle of the upper surface of the movable frame 6. A hydraulic rod 15 for providing and adjusting tension is provided between the support frame 2 and the movable frame 6. A connecting frame 7 for connecting a rack is fixedly connected to one side of the outer wall of the movable frame 6. A rack plate for converting linear motion into rotational motion is fixedly connected to the lower surface of the connecting frame 7. 8. A hinge seat 9 for providing a pivot point for rotation is fixedly connected to one side of the outer wall of the bottom frame 1. A rotating rod 10 for transmitting rotational motion is rotatably connected inside the hinge seat 9. The rotating rod 10 is fixedly connected to the outer wall of the rotating rod 10. This structure is used to transmit torque. A gear 11 that meshes with the rack plate 8 is rotatably connected to the outer wall of the rotating rod 10. The gear 11 meshes with the tooth end of the rack plate 8, realizing the conversion between the linear motion of the moving frame 6 and the rotational motion of the rotating rod 10. A rotating plate 12 for mounting the tension roller 13 is fixedly connected to the outer wall of the rotating rod 10. The tension roller 13 that directly contacts the membrane material and senses tension is rotatably connected inside the rotating plate 12.

[0028] Specifically, through the cooperation of hydraulic rod 15 and moving frame 6, tension roller 13 can move in real time when the film tension changes. Then, through the linkage of rack plate 8 and gear 11, this movement is converted into the rotation and position adjustment of tension roller 13, thereby realizing dynamic and real-time compensation of film tension and ensuring that the tension of multiple rolls of film remains consistent during the feeding process. At the same time, the setting of limit roller 13 and limit roller 24 ensures the precise guidance of film feeding, and together solves the problems of unstable feeding, wrinkling or tearing caused by uneven tension of multiple rolls of film, significantly improving the stability of feeding and production efficiency.

[0029] Reference Figure 1 - Figure 4A support frame 16 for supporting the feeding assembly is fixedly connected to the upper surface of the bottom frame 1. A V-shaped frame 20 with a symmetrical structure for holding multiple rolls of film is rotatably connected to one side of the outer wall of the support frame 16. This structure facilitates the placement and positioning of rolls of different specifications. A motor 17 for providing conveying power is fixedly connected to the upper side of the outer wall of the support frame 16. A transmission roller 18 for pulling the film forward is fixedly connected to the output end of the motor 17. A hydraulic rod 19 for controlling the position or attitude of the V-shaped frame 20 is provided between the other side of the outer wall of the support frame 2 and the V-shaped frame 20. A take-up roller 21 for carrying or guiding the initial roll of film is provided on the upper side of the V-shaped frame 20.

[0030] Specifically, by setting up a rotatable, left-right symmetrical V-shaped frame 20 as a carrying platform for multiple rolls of film, convenient loading of rolls of different specifications is realized; motor 17 drives transmission roller 18 to provide the main force for film material conveying, while the setting of hydraulic rod 19 realizes precise position control of V-shaped frame 20, which facilitates the replacement and adjustment of rolls; take-up roller 21 provides initial guidance and support for film material. All components work together to form a stable, controllable and highly adaptable multi-roll film material loading and conveying platform, providing a reliable foundation for subsequent tension compensation and synchronous conveying.

[0031] Reference Figure 1 - Figure 4 A support frame 22 for supporting the drive mechanism is fixedly connected to the upper surface of the bottom frame 1. The support frame 22 is located on one side of the tension roller 13. This position layout is conducive to realizing the linkage of the tension roller 13 and the effective traction of the film material. A motor 23 for providing conveying power is fixedly connected to the upper surface of the support frame 22. A transmission roller 24 for traction of the film material is fixedly connected to the output end of the motor 23. The transmission roller 24 works in conjunction with the transmission roller 18 to ensure the synchronous conveying of multiple rolls of film material. The outer wall of the rack plate 8 is installed through the inside of the hinge seat 9. This structure plays a guiding role. The lower surface of the rack plate 8 is slidably connected to the inner wall of the hinge seat 9 to ensure its stability and smoothness during movement.

[0032] Specifically, by adding support frame 22, motor 23, and transmission roller 24, a second set of driving force is provided for the synchronous conveying of the membrane material, enhancing the overall stability and reliability of the conveying process. At the same time, the through-and sliding connection structure of the rack plate 8 inside the hinge seat 9 provides precise guidance and support for the linear reciprocating motion of the rack plate 8 in the tension adjustment mechanism, ensuring the smoothness and accuracy of its motion, thereby ensuring the effective implementation of the real-time tension compensation function and jointly improving the overall performance and operational reliability of the equipment. Working principle: When the feeding mechanism is needed, firstly, multiple rolls of film are placed on the left and right symmetrical V-shaped frames 20. The V-shaped frames 20 are connected to the support frame 2 through the hydraulic rod 19, which facilitates the placement and fixing of the film rolls. After the film is drawn out from the V-shaped frame 20, it will pass through the winding roller 21, the limiting roller 3 on the support frame 2, and the limiting roller 14 on the moving frame 6 in sequence for effective guidance to ensure the accuracy of its travel path and prevent deviation. The membrane material is finally wound and passes through the tension roller 13, which is connected to the moving frame 6 via the rotating plate 12, rotating rod 10, gear 11, and rack plate 8. When the membrane tension changes, the tension acts on the tension roller 13 and causes the moving frame 6 to move slightly along the slide rail 4. The displacement of the moving frame 6 is sensed in real time by the hydraulic rod 15. The hydraulic rod 15 dynamically compensates for and adjusts the force acting on the moving frame 6 through its own extension and retraction. The hydraulic rod 15 pushes the moving frame 6 so that the connecting frame 7 drives the rack plate 8 to slide within the hinge seat 9 while engaging with the gear 11. The rotation of the gear 11 then drives the rotating plate 12 on the outer wall of the rotating rod 10 to rotate. The rotation of the rotating plate 12 precisely controls the position of the tension roller 13, thereby achieving real-time monitoring and dynamic adjustment of the membrane tension, ensuring that the membrane tension remains constant throughout the entire conveying process and that each roll remains consistent. At the same time, motor 17 and motor 23 drive transmission roller 18 and transmission roller 24 to rotate synchronously, jointly pulling multiple rolls of film material, achieving stable and consistent synchronous feeding. The entire mechanism forms a precise closed-loop control system through the linkage of tension roller 13, hydraulic rod 15, gear 11 and rack plate 8, which completely solves the problems of unstable feeding, material wrinkling or tearing caused by differences in film roll diameter and winding tightness, and greatly improves the production efficiency and product quality of the equipment.
