Description

Technical Field

[0001] The utility model relates to the technical field of film laminating machines, in particular to a film pulling and feeding device for film laminating machines. Background Art

[0002] With the advancement of technology, the performance and functions of film laminating machines are constantly improving. Modern film laminating machines are equipped with higher-precision sensors and intelligent control systems, which can achieve more accurate and stable film laminating operations. The degree of automation of film laminating machines is getting higher and higher, and the entire process from film roll loading, cutting, positioning to film laminating can be automated. Some advanced film laminating machines are equipped with visual systems and machine learning algorithms, which can achieve automatic recognition, positioning and laminating.

[0003] Although the current film laminating machine can realize complex film laminating work, the film pulling device equipped with it is still developing slowly, the film pulling device fails frequently, and the work of adjusting the film material tension by the film pulling device is complicated. For the film material with self-adhesive effect, it is difficult to separate the self-adhesive film from the layered film, which often requires manual intervention, resulting in low work efficiency;

[0004] For example, the Chinese patent CN109760296B discloses an automatic film laminating machine film laminating method, which includes five parts: basic component, transmission component, film laminating component, cleaning component, and interactive device. Among them, the basic component includes a dustproof shell, a base and a frame; the transmission component includes a conveyor belt, a positioning plate, and a material frame, in which there are mobile phone locators of different models with embedded NFC near-field communication chips; the film laminating component includes sliding guide rails, pulleys, and connecting rods, and the other end of the connecting rod is hinged with a film laminating suction device including an NFC sensing chip and a vacuum suction cup; the cleaning component includes a wiping mechanism and a scraper mechanism; the interactive device includes a touch screen;

[0005] For example, the automatic film laminating machine involved in the above patent can achieve the purpose of improving the accuracy of film laminating. However, if the film needs to be laminating through a self-adhesive film, it is basically difficult to separate the self-adhesive film, resulting in low working efficiency of the film laminating machine, and low efficiency in stripping and cutting the film material;

[0006] For example, Chinese patent CN116495536A discloses an automatic winding device for waterproof film without a winding core and a winding method for waterproof film, which comprises a frame and a winding mechanism, a material head guiding mechanism, a tape sticking mechanism, a cutting mechanism, a feeding mechanism and a discharging mechanism arranged on the frame, wherein the winding mechanism comprises a first driving member and an inflatable shaft, the inflatable shaft is provided with a fixed sheet and a movable sheet, the fixed sheet cooperates with the key strip of the inflatable shaft to fix the waterproof film, the feeding mechanism is used to transport the waterproof film to a predetermined position of the inflatable shaft, the material head guiding mechanism is used to ensure that the material head of the waterproof film is transported to a designated position, the tape sticking mechanism comprises a glue sticking assembly, the glue sticking assembly is used to fix the tape to stick the tape on the waterproof film and to cut the tape, the cutting mechanism is used to cut the waterproof film, and the discharging mechanism is used to push the roll material out of the inflatable shaft;

[0007] The above patent is used for automatic winding of waterproof film, and its purpose is to wind up the waterproof film and perform related processing. It cannot be used to tear off the adhesive film with a diaphragm and wind up the diaphragm. It is mainly used to cut and wind up the waterproof film with an adhesive. Therefore, the design purpose of the device is not suitable for tearing off and pasting the adhesive film. When pasting the film on the workpiece, if the adhesive film has a diaphragm, the device cannot be used, and it cannot improve the work efficiency when pasting the adhesive film with a diaphragm.

[0008] For example, a battery film making and winding device disclosed in Chinese patent CN209226250U includes a controller and a film making and winding device electrically connected to the controller; the film making and winding device includes a first vertical plate, a second vertical plate, a pole piece unwinding mechanism, a pole ear welding mechanism, a pasting mechanism, a pole piece winding mechanism, at least one first fixed roller, at least one second fixed roller, a first tension swing arm mechanism and a second tension swing arm mechanism, and the controller controls the pole piece unwinding mechanism, the pole ear welding mechanism, the pasting mechanism and the pole piece winding mechanism combination to make pole pieces;

[0009] The above patent is used for film production and winding in the lithium battery production process. By adjusting the tension change of the winding mechanism, the pole piece can be evenly and stably conveyed to a precise position. Since the film material of the film laminating machine is conveyed with adhesive backing, and the adhesive backing side needs to be isolated by a diaphragm, the diaphragm needs to be removed during automatic laminating, and the adhesive backing film will adhere to the surface of the tension adjustment mechanism. The device cannot adjust the tension of the adhesive backing film with a diaphragm, nor can it automatically strip the adhesive backing film with a diaphragm.

[0010] Therefore, a film-drawing and feeding device is needed that can improve the film-sticking efficiency of an automatic film-sticking machine. Utility Model Content
