[0002] Roll-fed flexible packaging equipment, such as gravure printing machines, dry laminating machines, wet laminating machines, solvent-free laminating machines and coating machines, all have a winding operation process.

Special material winding rollers use a non-contact type, that is, the roller does not contact the material on the reel. As a result, existing structures can only adapt to a specific material, resulting in a single machine being unable to adapt to a variety of different materials, reducing production efficiency.

DETAILED DESCRIPTION

[0021] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0022] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0023] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0024] See also Figure 1-Figure 7 In the embodiment of the utility model, a roller device that moves with the winding diameter is installed on the frame 1 and is located on one side of the self-powered reel, including a roller 5, a driving device and a detection module.

[0025] The driving device is installed on the frame 1, including two symmetrically arranged transverse moving components, and the supporting roller 5 is rotatably installed between the two transverse moving components; the detection module is installed on the transverse moving component, including an automatic detection unit and an extrusion detection unit, and the automatic detection unit and the extrusion detection unit establish communication with the transverse moving component, and are used to control the transverse moving component to drive the supporting roller 5 to move in a direction away from the reel when the automatic detection unit or the extrusion detection unit is triggered.

[0026] In this embodiment, the automatic detection unit and the extrusion detection unit are arranged to adapt to contact and non-contact winding to meet different winding requirements. At the same time, when the automatic detection unit fails, the extrusion detection unit performs a triggering action, which can effectively ensure the normal winding work. At the same time, the automatic detection unit and the extrusion detection unit ensure that the support roller 5 is in a dynamic moving state, and the length of the material between the surface of the material on the roll and the support roller 5 remains approximately constant, ensuring that the material is wound smoothly, and effectively improving the winding quality.

[0027] Specifically, see Figure 1-Figure 4 The transverse movement assembly includes a receiving frame 14 slidably mounted on the frame 1; a screw rod 9 that penetrates the receiving frame 14 and is threadedly connected to the receiving frame 14, and the screw rod 9 is rotatably mounted on the frame 1 and driven to rotate by a driving source.

[0028] Among them, at least one first sliding block 12 is installed on the receiving frame 14, and the first sliding block 12 is slidably connected to the slide rail 11 installed on the frame 1 to achieve the receiving of the receiving frame 14 and ensure that the receiving frame 14 can slide in a directional manner.

[0029] Exemplarily, in one embodiment, the driving source includes a second motor 8 installed on the frame 1 and a transmission shaft 7 rotatably installed on the frame 1 and axially perpendicular to the screw rod 9. The transmission shaft 7 is rotationally connected to the screw rod 9 through a second transmission member 13, and one end of the transmission shaft 7 is connected to the output shaft of the second motor 8. The second motor 8 drives the transmission shaft 7 to rotate when working. When the transmission shaft 7 rotates, it drives the screw rod 9 to rotate through the second transmission member 13. When the screw rod 9 rotates, it drives the receiving frame 14 to move along the axial direction of the screw rod 9, thereby driving the roller 5 to move to achieve the driving requirement.

[0030] Preferably, two travel switches 23 are installed below the screw rod 9 , and the two travel switches 23 are located at the beginning and end of the travel of the receiving frame 14 , thereby achieving effective control over the movement of the receiving frame 14 .

[0031] See also Figure 2 , Figure 5 and Figure 6The extrusion detection unit includes a movable frame 16 slidably mounted on the supporting frame 14, and the supporting roller 5 is rotatably mounted on the movable frame 16; it also includes a cylinder 15, the cylinder 15 is hinged on the supporting frame 14, and the movable end of the cylinder 15 is connected to the movable frame 16 through a pin 22, and a magnetic switch 24 that can be triggered by the pin 22 is provided on the supporting frame 14, and the magnetic switch 24 establishes communication with the control unit of the second motor 8.

[0032] In the initial state, the pin 22 and the magnetic switch 24 are in an offset state. When the film material on the roll is wound up a certain amount, an extrusion force is generated on the roller 5, and the roller 5 moves in the direction away from the roll, so that the extrusion cylinder 15 contracts, and the pin 22 follows the movement. When the pin 22 moves to face the magnetic switch 24, it sends a signal to the control unit, and the control unit controls the second motor 8 to work, thereby driving the receiving frame 14 and the movable frame 16 installed on the receiving frame 14 and the roller 5 to move as a whole, so as to ensure that the pressure between the roller 5 and the film material on the roll is relatively constant, ensure that the material is wound smoothly, and effectively improve the winding quality.

[0033] It should be additionally explained that a second sliding block 20 is installed on the movable frame 16 , and the second sliding block 20 is slidably connected to a sliding groove 21 on the receiving frame 14 .

[0034] Preferably, a synchronization shaft 10 is rotatably mounted on the movable frame 16 , and synchronization gears 18 are fixed to both ends of the synchronization shaft 10 . The synchronization gears 18 are meshed with synchronization racks 19 fixed on the receiving frame 14 , thereby ensuring the consistency of movement of the movable frame 16 relative to the receiving frame 14 .

[0035] A guide roller 6 is rotatably mounted between the two movable frames 16 to change the winding direction of the film material.

[0036] See also Figure 2 The automatic detection unit includes a beam switch 17 installed on the receiving frame 14. The two beam switches 17 on the two receiving frames 14 are arranged opposite to each other. The beam switch 17 establishes communication with the control unit of the second motor 8. The two beam switches 17 are used to detect the change in the roll diameter of the film material on the roll. When the film material blocks the beam switch 17, the beam switch 17 feeds back a signal to the control unit, thereby controlling the second motor 8 to work, so that the roller 5 moves a distance, and the position of the beam switch 17 also changes accordingly, thereby re-measuring the change in the roll diameter of the film material on the roll.

[0037] For further information, see Figure 1The two ends of the reel are detachably connected to the plug 4 rotatably mounted on the frame 1, and one of the rotating shafts of the plug 4 is connected to the first motor 2 mounted on the frame 1 through the first transmission member 3. The first motor 2 drives the plug 4 to rotate through the first transmission member 3, thereby driving the reel to rotate, thereby realizing the requirement of continuous rotation of the reel for winding the film material.
