[0002] The film winding machine, also known as the roll changing machine, is a key equipment in the film production equipment. It can control the conversion between the two stations through the motor, and release the film from the station for subsequent production and processing. The two stations of the roll changing machine are each equipped with an independent transmission system. Its overall performance and precision play a decisive role in the quality and efficiency of subsequent film production.

[0025] In this embodiment, the film material winding machine has two workstations, which include a bearing seat 61, a first chuck 62, an inflatable shaft 63, a second chuck 65, a chuck cylinder 66, a telescopic shaft 67 and a linear bearing 67. The bearing seat 61 is fixed on the first flip plate 15, and the first chuck 62 is arranged on one side of the bearing seat 61. A card key is provided inside the first chuck 62, and the card key corresponds to the card groove on the inflatable shaft 63, which can clamp the inflatable shaft 63 for axial fixation. The linear bearing 67 is fixed on the second flip plate 16. A telescopic shaft 67 that can move linearly is provided in the linear bearing 67. A second chuck 65 is provided at one end of the telescopic shaft 67. A detachable inflatable shaft 63 is provided between the first chuck 62 and the second chuck 65.

The workstation is located between the two flip plates, and there is one on each side.

[0026] In this embodiment, the workstation transmission system is composed of two independent subsystems. The transmission system 1 includes a first servo motor 4, a first planetary reducer 41, a first main sprocket 42, a first chain 43, a first slave sprocket 44, a first main drive sprocket 45, a first drive chain 46 and a first slave drive sprocket 47. The first main sprocket 42 is fixedly connected to the first planetary reducer 41 through a flat key, and the first main sprocket 42 is connected to the first slave sprocket 44 through a first chain 43. The first main sprocket 42 is driven to rotate by the first servo motor 4, and the power is transmitted to the first slave sprocket 47 through the first chain 43. Among the slave sprockets 44, the first slave sprocket 44 and the first main drive sprocket 45 are fixed on the same axis and can rotate synchronously. The power is transmitted to the first slave drive sprocket 47 through the first drive chain 46, thereby realizing power transmission from the first servo motor 4 to the first slave drive sprocket 47. The transmission system 2 includes a second servo motor 5, a second planetary reducer 51, a second chain 52, a second main sprocket 53, a second slave sprocket 54, a second main drive sprocket 55, a second drive chain 56 and a second slave drive sprocket 57. The transmission system 1 and the transmission system 2 have the same working principle.

[0027] In this embodiment, the cutting device includes a second cylinder 78, a first cutting cylinder 781, a cutting swing arm 782, a cutting rocker 783, a cutting knife 784, a rubber roller 785, a rubber roller rocker 786 and a rubber roller cylinder 787. The second cylinder 78 is provided on one side of the first wall panel 7 and can control the swing and lifting of the cutting swing arm 782. The cutting swing arm 782 is provided between the two wall panels and one on each side. The first cutting cylinder 781 and the rubber roller cylinder 787 are fixed by hanging ears. On the cutting swing arm 782, the cylinder can rotate within a certain angle range. The first cutting cylinder 781 is used to control the cutting knife 784 to cut the film material. The rubber roller cylinder 787 is used to control the rubber roller 785 to make the transition film material fit during the connection process. The cutting knife 784 is fixed on the cutting rocker 783. The first cutting cylinder 781 can control the swing of the cutting rocker 783. The rubber roller 785 is installed on the rubber roller rocker 786, and its swing is controlled by the rubber roller cylinder 787.

[0028] The specific usage and function of this embodiment are as follows: First, turn on the equipment, then operate the cylinder control valve to extend the chuck cylinder 66. This action will drive the telescopic shaft 67 to push back, thereby separating the second chuck 65 from the inflatable shaft 63. At this time, remove the inflatable shaft 63 from the equipment and insert it into the pre-prepared film material 6. Use a cart to lift the film material 6 and the inflatable shaft 63 together to the coaxial axis of the first chuck 62 and the second chuck 65. Then align the card slot on the inflatable shaft 63 with the card key in the chuck, rotate the cylinder control valve, control the chuck cylinder 66 to contract, so that the two chucks tightly clamp the inflatable shaft 63, and then use an air gun to inflate the inflatable shaft 63 to tighten the film material 6. Operate the control panel to drive the motor 2 to rotate, causing the flip device to rotate 180°, switch the work station for loading the film material 6 to a position close to the cutting device, and then slowly pull out the film material 6, guiding it through the second guide roller 73, the floating roller 75 and the third guide roller 74 in turn.

[0029] The first servo motor 4 is started through the control panel, and its power is transmitted through the first planetary reducer 41 to drive the first main sprocket 42 to rotate. The first main sprocket 42 drives the first slave sprocket 44 to rotate through the first chain 43. The first slave sprocket 44 rotates coaxially with the first main drive sprocket 45, and then drives the first slave drive sprocket 47 to rotate through the first main drive chain 46. Finally, the rotation of the first slave drive sprocket 47 drives the inflatable shaft 63 to rotate, so that the film material 6 on the inflatable shaft 63 starts to rotate and discharge, and the film material 6 is transported backward and starts further production and processing.

[0030] When the equipment is running, the film material 6 is continuously output. When the film material 6 is about to be used up, the new film material is transported to the site in advance and installed on the air shaft 63 of the work station near the outside. At the same time, double-sided tape is pasted on the surface of the new film material. Then, the second servo motor 5 of the work station corresponding to the new film material is started through the control panel to control the new film material to start rotating, and the speed of the two servo motors is kept consistent. When the roll change operation is required, the control panel is operated to turn the flip mechanism 225° counterclockwise to allow the new film material to be tilted downward and close to the cutting device. At this time, the remaining part of the film material 6 continues to be released, and after being guided by the first guide roller 64, it is in the middle position between the cutting device and the new film material. After pressing the roll change button, the second cylinder 7 8 extends out, controls the cutting swing arm 782 to lift, and then the rubber roller cylinder 787 drives the rubber roller 785 to fit the new film material, and the film material 6 released is still transmitted between the rubber roller 785 and the new film material. When the double-sided tape on the new film material fits the film material 6, the film material 6 will drive the new film material to start releasing. At this time, the equipment is conveying two films at the same time. In order to complete the roll change, the cutting device is required to cut the film material 6. The first cutting cylinder 781 controls the cutting rocker 783 to swing, and then the cutting knife 784 on the cutting rocker 783 cuts the film material 6, realizing the roll change of the film material. After the film material is cut, the turning device rotates to make the station of the new film material close to the cutting device, thereby completing the entire roll change process.

[0031] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
