Description

Technical Field

[0001] This utility model belongs to the field of membrane processing technology, specifically a misalignment correction device for membrane bonding. Background Technology

[0002] Films are typically manufactured using laminating equipment. This involves unwinding and rewinding a roll of film, then flattening it using traction rollers, cooling it, and finally winding it up with take-up rollers to obtain the finished film. Different film materials have different properties, and in some special applications, it is necessary to combine the properties of different materials, requiring double-layer or multi-layer films. Ordinary laminating equipment can only produce a single layer of film, thus failing to meet practical needs. Currently, the production of double-layer or multi-layer films generally involves first laminating the first and second layers of film, and then laminating the third layer to the already laminated film, requiring a film laminating machine.

[0003] When the two existing membrane materials are laminated, if the device vibrates or shakes, one of the membrane materials will shift slightly in the lateral direction. This can only be detected by manual observation. However, the feeding roller and feeding rack of the existing device are set in fixed positions. If they cannot be detected by manual observation in time, the two membrane materials will not be able to fully cover and laminate together, which will greatly affect the quality of the finished membrane material. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a misalignment correction device for film bonding, which has the advantage of improving the bonding quality of finished products.

[0005] The purpose of this utility model can be achieved through the following technical solution: a offset correction device for film bonding, including a worktable and a table cover, wherein an unwinding mechanism, a guiding mechanism and a pressing mechanism are installed on the worktable and the table cover.

[0006] The unwinding mechanism includes drive boxes symmetrically arranged on the worktable and the table cover. A first drive motor is installed on one side of the drive box.

An unwinding roller is driven and detachably connected to the unwinding frame. A roll of film material is on the unwinding roller.

[0007] The drive box also has connecting frames on both sides. A first lifting motor is fixed on the connecting frame, and a lifting plate is fixed on the first lifting motor. An infrared ray emitter is installed on the lifting plate on the connecting frame of the platform in the direction close to the membrane material. An infrared ray receiver is installed on the lifting plate on the connecting frame of the workbench in the direction close to the membrane material, for detecting whether the membrane material has shifted.

[0008] The guiding mechanism includes a first guide roller symmetrically arranged on the platform cover, a heating roller installed at the center of the side wall of the platform cover, and a guide frame symmetrically installed between the worktable and the platform cover, wherein a second guide roller is drivenly connected to the guide frame;

[0009] The pressing mechanism includes a mounting plate mounted on a platform cover and a mounting plate mounted on a workbench. A second lifting motor is mounted on the mounting plate, a second lifting frame is fixed on the second lifting motor, and a pressing roller is mounted on the second lifting frame for pressing two films together.

[0010] Preferably, it also includes a winding mechanism, which includes a winding frame and a winding roller. The winding frame is mounted on a workbench, and the winding roller is drivenly connected to the winding frame.

Detailed Implementation

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, a misalignment correction device for film bonding includes a worktable 2 and a table cover 3, characterized in that an unwinding mechanism, a guiding mechanism and a pressing mechanism are installed on the worktable 2 and the table cover 3.

[0022] The unwinding mechanism includes a drive box 41 symmetrically arranged on the workbench 2 and the table cover 3. A first drive motor 42 is installed on one side of the drive box 41. A lead screw 43 is driven and connected to the output shaft of the first drive motor 42. A guide rail 44 is installed inside the drive box 41. A sliding seat 45 is slidably arranged on the guide rail 44. The lead screw 43 is connected to the sliding seat 45. The drive box 41 has a through hole 46. The sliding seat 45 is fixed to the unwinding frame 47 through the through hole 46. An unwinding roller 48 is driven and detachably connected to the unwinding frame 47. The unwinding roller 48 has a roll of film material on it.

[0023] The drive box 41 also has connecting frames 51 on both sides. A first lifting motor 52 is fixed on the connecting frame 51. A lifting plate 53 is fixed on the first lifting motor 52. An infrared ray emitter 54 is installed on the lifting plate 53 on the connecting frame 51 of the platform cover 3 in the direction close to the membrane material. An infrared ray receiver 55 is installed on the lifting plate 53 on the connecting frame 51 of the worktable 2 in the direction close to the membrane material, for detecting whether the membrane material has shifted.

[0024] The guiding mechanism includes a first guide roller 61 symmetrically arranged on the platform cover 3, a heating roller 62 installed at the center of the side wall of the platform cover 3, and a guide frame 63 symmetrically installed between the worktable 2 and the platform cover 3. A second guide roller 64 is drivenly connected to the guide frame 63.

[0025] The pressing mechanism includes a mounting plate 71 mounted on the platform cover 3 and a mounting plate 71 mounted on the worktable 2. A second lifting motor 72 is mounted on the mounting plate 71, a second lifting frame 73 is fixed on the second lifting motor 72, and a pressing roller 74 is mounted on the second lifting frame 73 for pressing two films together.

[0026] In this invention, the infrared ray emitter 54 and the infrared ray receiver 55 are existing technologies.

[0027] The distance between one of the infrared ray emitters 54 and the other infrared ray emitter 54 is greater than the width of the membrane material.

[0028] The infrared ray emitter 54 is positioned directly below the infrared ray receiver 55.

[0029] With the above structure, before the two membrane materials are bonded together, infrared ray emitters 54 and infrared ray receivers 55 are added to both sides of the membrane material. This facilitates real-time detection of whether the membrane material has shifted during transport. If the membrane material shifts to one side, even though the distance between the two infrared ray emitters 54 is greater than the width of the membrane material, as long as the membrane material shifts to one side, the rays emitted by the infrared ray emitters 54 will be blocked by the membrane material. The rays emitted by the infrared ray emitters 54 located on both sides of the membrane material are blocked by the membrane material, so that the infrared ray receivers 55 cannot receive the rays. By transmitting an electrical signal indicating that the rays cannot be received, the first drive motor 42 on one side of the drive box 41 is started, which drives the lead screw 43 to rotate. The lead screw 43 can convert the rotary motion into linear motion, which drives the sliding seat 45 to move slightly in the opposite direction of the corresponding shift, so that the membrane material returns to the pre-set transport position. This facilitates timely handling of membrane material shift problems, automatically corrects membrane material shifts, greatly improves the quality of the finished membrane material, helps reduce membrane material loss caused by shifts, results in higher bonding quality, and enhances practicality.

[0030] Specifically, such as Figures 1 to 3 As shown, it also includes a winding mechanism, which includes a winding frame 81 and a winding roller 82. The winding frame 81 is mounted on the workbench 2, and the winding roller 82 is drivenly connected to the winding frame 81.

[0031] With the above structure, the winding roller 82 facilitates automatic winding and makes it easier to wind up the laminated film.

[0032] like Figures 1 to 3As shown, both film materials are fed from the unwinding roller 48, and sequentially pass through the first guide roller 61, the second guide roller 64, the heating roller 62, and the pressure roller 74, and are finally wound up by the winding roller 82. Through the above steps, the film materials are conveyed and offset corrected, heated and bonded by the heating roller 62, and then wound up, making the process simpler and more convenient to operate.

[0033] like Figures 1 to 3 As shown, the sliding seat 45 has a sliding part, and the guide rail 44 has a sliding groove, with the sliding part and the sliding groove slidingly engaged. This sliding engagement facilitates timely and rapid detection and correction of membrane material misalignment, resulting in faster operation and greater practicality.
