Description

Technical Field

[0001] This utility model relates to the field of sheet composite technology, and in particular to a sheet composite device based on sheet packaging. Background Technology

[0002] In existing technologies, flexible sheet winding is a process that continuously winds flexible materials (such as films, foils, etc.) onto a roll, and it is widely used in industries such as packaging, electronics, and textiles. Its core process aims to achieve efficient and smooth winding, avoiding material damage or winding defects.

[0003] Some flexible sheets require a protective film to be laminated on the surface of the sheet during the winding process to ensure the integrity of the sheet itself and prevent the sheets from adsorbing each other under static electricity, which would be detrimental to unwinding.

[0004] In the process of applying protective film to existing flexible sheets, the guide rollers are usually used for direct lamination, followed by direct winding. This operation can easily cause air bubbles to form between the sheet and the protective film, which may cause deformation of the sheet and make it difficult to wind up. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sheet composite device based on sheet packaging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sheet composite device based on sheet packaging, comprising: A mounting plate for installing the overall device has a sheet feed roller shaft rotatably mounted on one side of its front for introducing flexible sheet material. A preliminary composite roller shaft is provided on one side of the sheet feed roller shaft, an exhaust roller shaft is provided on one side of the preliminary composite roller shaft, a guide roller shaft is provided on one side of the exhaust roller shaft, and a take-up roller shaft is provided above the guide roller shaft. A connecting roller shaft for introducing a protective film is provided above the connecting roller shaft, and an unwinding roller shaft is provided above the connecting roller shaft. The exhaust roller shaft is configured as two, one above the other, with a film-coated rubber sleeve fixedly fitted to the outer wall of the upper roller shaft; the preliminary composite roller shaft is used for preliminary composite of flexible sheet and protective film; the winding roller shaft is used for winding the composite flexible sheet and protective film; the film-coated rubber sleeve is made of flexible rubber with its outer wall protruding outward in the middle.

[0007] As a further improvement of this utility model, angular velocity sensors are provided above the sheet feeding roller shaft, below the preliminary composite roller shaft, and below the guide roller shaft.

[0008] As a further improvement of this utility model, thickness detection sensors are provided above both the take-up roller shaft and the unwinding roller shaft.

[0009] As a further embodiment of this utility model: a supporting base plate is fixedly connected to the bottom end of the mounting plate, and a main controller and a servo motor for driving the sheet material feeding roller shaft are fixedly installed on the upper surface of the supporting base plate.

[0010] As a further embodiment of this utility model: a second servo motor is connected to the tail end of the take-up roller shaft, and a third servo motor is connected to the tail end of the take-out roller shaft. Both the second and third servo motors are fixedly installed on the back of the mounting plate.

[0011] As a further embodiment of this utility model: the sheet feeding roller shaft, the preliminary composite roller shaft, the exhaust roller shaft and the guide roller shaft are all provided in pairs, and one of the sheet feeding roller shaft, the preliminary composite roller shaft and the guide roller shaft is connected by a sprocket and chain drive.

[0012] As a further embodiment of this utility model: an electric telescopic rod is fixedly installed on the back of the mounting plate, and a connecting slide rod is fixedly installed at the telescopic end of the electric telescopic rod.

[0013] As a further improvement of this utility model: a rotating mounting bracket is fixedly installed at the end of the connecting slide rod, and a tensioning wheel is rotatably installed inside the rotating mounting bracket.

[0014] Compared with the prior art, this utility model provides a sheet composite device based on sheet packaging, which has the following beneficial effects: This sheet laminating device based on sheet packaging uses an angular velocity sensor to monitor the speed differences of the guide roller, the preliminary laminating roller, and the sheet feeding roller in real time. Combined with an electric telescopic rod, it automatically adjusts the chain tension to achieve synchronized speeds of the three rollers. A servo motor dynamically adjusts its output speed based on the real-time thickness of the protective film and the composite sheet, ensuring a constant feeding speed and effectively avoiding the misalignment or wrinkling problems caused by variations in material thickness in traditional devices. The exhaust roller features a film-coated rubber sleeve design, with a convex center forming a gradient pressure zone. The pressure is highest in the middle and gradually decreases at both ends, effectively expelling air between the sheet and the protective film, significantly improving lamination tightness and reducing air bubble residue.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

An electric telescopic rod 28 with controllable stroke (mature technology, suitable models can be selected from the market) is fixedly installed inside the mounting base 27.

[0030] The tail end of the take-up roller shaft 8 passes through the mounting plate 2 and is rotatably connected to the mounting plate 2. The tail end of the take-up roller shaft 8 is connected to the servo motor 24 via a coupling. The servo motor 24 is mounted on the back of the mounting plate 2 via a motor mount.

[0031] The outer wall of the output roller 10 is fitted with a protective film 11 roll, and the tail end of the output roller 10 passes through the mounting plate 2 and is rotatably connected to the mounting plate 2.

[0032] An angular velocity sensor 14 is installed above the upper sheet feed roller 3, below the lower preliminary composite roller 4, and below the left guide roller 7. A mounting bracket 13 is fixedly installed on the back of the angular velocity sensor 14 and is fixedly installed on the front of the mounting plate 2.

[0033] A main controller 26 is also installed at the tail end of the upper surface of the support base plate 1. The main controller 26 is connected to the angular velocity sensor 14, the thickness detection sensor 16, the servo motors (servo motor 1 20, servo motor 24 and servo motor 3 25) and the electric telescopic rod 28 through wires. It receives feedback data from the angular velocity sensor 14 and the thickness detection sensor 16 and controls the corresponding servo motor or electric telescopic rod 28.

[0034] Working principle: Please refer to Figures 1 to 4 Assemble the device as shown in the figure; The protective film 11 roll is mounted on the unwinding roller 10. The thickness of the film roll is detected by the corresponding thickness detection sensor 16 (the distance between the thickness detection sensor 16 and the unwinding roller 10 is fixed). The detection data is then transmitted to the main controller 26.

The detection data is then transmitted to the main controller 26. The main controller 26 determines the take-up speed of the sheet roll based on the data, and then determines the output speed of the third servo motor 25 (the output speed of the third servo motor 25 gradually decreases as the thickness of the sheet roll decreases). The main controller 26 determines the output speed of the servo motor 20 based on the actual situation (the tensile capacity of the flexible sheet 12 and the protective film 11), so that the feeding speed of the flexible sheet 12 and the output speed of the protective film 11 roll are the same. Then, based on the rotation speed of the guide roller shaft 7, the rotation speed of the preliminary composite roller shaft 4, and the rotation speed of the sheet feeding roller shaft 3 fed back by the angular velocity sensor 14, it controls the extension and retraction of the electric telescopic rod 28 and adjusts the tension of the corresponding chain to make the rotation speeds of the three the same, thereby ensuring that the feeding speeds of the flexible sheet 12 and the protective film 11 are the same and ensuring the composite effect.
