[0004] An embodiment of this application provides a continuously feedable laminating machine, including a conveying member, at least two film supply mechanisms are arranged on the conveying member, the film supply mechanism includes a lifting frame, a hollow roller is arranged on the lifting frame, a support member is arranged on the lifting frame, a film roll is installed on the support member, air holes are formed on the outer circumference of the roller, the roller is communicated with an external negative pressure machine, and a film sensor is arranged at the film roll.

[0005] In a specific implementation, the conveying member includes a frame and a conveyor belt, and the conveyor belt is installed on the frame.

[0006] In the above implementation process, the glass is conveyed along the conveyor belt, and the film is pressed onto the surface of the glass through the film supply mechanism on the frame to achieve lamination.

[0007] In a specific implementation, the lifting frame includes a support and a sliding frame, the support is fixedly connected to the frame, the sliding frame is slidably connected to the support, and the roller is rotatably connected to the sliding frame.

[0008] In a specific implementation, a smooth rod is arranged on the support, the sliding frame is slidably connected along the smooth rod, and a spring is arranged between the sliding frame and the support.

[0009] In the above implementation process, the spring maintains a tendency to press the sliding frame downward, so as to press the roller onto the glass on the conveyor belt. In this embodiment, the film sensor is a photoelectric sensor, which is installed on the support through an adjustable frame, and judges whether the current film roll is used up and whether the film supply mechanism needs to be switched through the feedback of the light emitted by the photoelectric sensor and irradiated on the film surface.

[0010] In a specific implementation, an electromagnetic telescopic rod is installed on the sliding frame.

[0011] In the above implementation process, the electromagnetic telescopic rod is used to lift the carriage, thereby raising the roller.

[0016] In the above implementation process, the screw is used to adjust the position in advance so that the film roll is aligned with the glass below, and then it is fixed by tightening the nut. When loading and unloading the film roll, only the cylinder needs to be controlled to expand and contract. In this way, the plugs at both ends can be inserted into or pulled out of the holes at both ends of the film roll, facilitating disassembly.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0025] Please refer to Figures 1 - 4 , the present application provides a continuous feeding film laminating machine, which includes a conveying member 100, and at least two film supply mechanisms 200 are arranged on the conveying member 100. The film supply mechanism 200 includes a lifting frame 210, a hollow rotating roller 220 is arranged on the lifting frame 210, a support member 230 is arranged on the lifting frame 210, a film roll 240 is installed on the support member 230, air holes 221 are formed on the outer circumference of the rotating roller 220, the rotating roller 220 is communicated with an external negative pressure machine, and a film sensor 250 is arranged at the film roll 240. Among them, the film sensor 250 is used to detect whether the film on the film roll 240 is used up, so as to trigger the alternating film lamination of multiple film supply mechanisms 200, achieving the effect of continuous feeding and improving the processing efficiency.

[0026] Please refer to Figures 1 - 4 , the conveying member 100 includes a frame 110 and a conveyor belt 120, and the conveyor belt 120 is installed on the frame 110. The glass is conveyed along the conveyor belt 120, and the film is pressed onto the surface of the glass through the film supply mechanism 200 on the frame 110 to achieve film lamination.

[0027] Please refer to Figures 1 - 4 , the lifting frame 210 includes a bracket 211 and a sliding frame 212. The bracket 211 is fixedly connected to the frame 110, the sliding frame 212 is slidably connected to the bracket 211, and the rotating roller 220 is rotatably connected to the sliding frame 212. An optical rod 213 is arranged on the bracket 211, the sliding frame 212 is slidably connected along the optical rod 213, and a spring 214 is arranged between the sliding frame 212 and the bracket 211. The spring 214 maintains a tendency to press the sliding frame 212 downward, so as to press the rotating roller 220 onto the glass on the conveyor belt 120. In this embodiment, the film sensor 250 is a photoelectric sensor, which is installed on the bracket 211 through an adjustable frame, and judges whether the current film roll 240 is used up and whether the film supply mechanism 200 needs to be switched by the feedback of the light emitted by the photoelectric sensor irradiating the film surface.

[0028] Please refer toFigures 1 - 4 , an electromagnetic telescopic rod 215 is installed on the carriage 212. The electromagnetic telescopic rod 215 is used to lift the carriage 212, thereby lifting the roller 220. It should be noted that when the roller 220 is lifted, the film between the roller 220 and the film roll 240 remains in a bent and relaxed state. In this way, when the roller 220 presses down, it can drive the lower end of the film to move downward, avoiding the situation where the film is torn off.

[0029] Please refer to Figures 1 - 4 , a rotary joint 222 is provided at one end of the roller 220. The rotary joint 222 is used to keep the roller 220 connected to the hose of the external negative pressure machine during rotation. It should be noted that an electromagnetic valve is provided outside each rotary joint 222. When the roller 220 presses the film onto the glass, the electromagnetic valve interrupts the negative pressure so that the film can be separated from the roller 220.

[0030] Please refer to Figures 1 - 4 , the support member 230 includes a cylinder 231 and a screw 232. The cylinder 231 is installed on the bracket 211 on one side, and the screw 232 is threadedly connected to the bracket 211 on the other side. The telescopic end of the cylinder 231 and the inner end of the screw 232 are both rotatably connected with a plug 233. A nut 234 is screwed on the screw 232, and the nut 234 is tightened on the bracket 211. The screw 232 is used to adjust the position in advance so that the film roll 240 can be aligned with the glass below, and then fixed by tightening the nut 234. When loading and unloading the film roll 240, only control the telescopic movement of the cylinder 231. In this way, the plugs 233 at both ends can be inserted into or pulled out of the holes at both ends of the film roll 240, facilitating disassembly.

[0031] The working principle of this continuous feeding film laminating machine is as follows: The film roll 240 is pre-loaded onto the support member 230, one end of the film is pulled out to the roller 220, negative pressure is achieved inside the roller 220 by using an external negative pressure machine, and one end of the film is adsorbed on the lower outer circumference of the roller 220 by using the air holes 221 on the surface. The electromagnetic telescopic rod 215 lifts the carriage 212, thereby lifting the roller 220 to make preparations. During film lamination, the film feeding mechanism 200 starts to work. The electromagnetic telescopic rod 215 contracts, and the carriage 212 drives the roller 220 with one end of the film to press onto the glass under the action of the spring 214. As the conveyor belt 120 drives the glass to move, the film is laminated onto the glass. When the current film roll 240 is used up and the photoelectric sensor cannot detect the presence of the film, the current roller 220 is triggered to lift, while the other roller 220 is lowered, and then film lamination continues. The original film roll 240 can be replaced for standby, achieving the effect of continuous feeding. In summary, the film sensor 250 is used to detect whether the film on the film roll 240 is used up, thereby triggering multiple film feeding mechanisms 200 to alternately laminate the film, achieving the effect of continuous feeding and improving the processing efficiency.

[0032] The above are only embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, improvement, or equivalent replacement made within the spirit and principle of the present application shall be included within the protection scope of the present application. It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
