[0028] Reference Figures 1 to 4 This application provides an automatic laminating device, including: a feeding mechanism, including a first feeding component 110 and a second feeding component 120, the first feeding component 110 being used for feeding and conveying paper, and the second feeding component 120 being used for feeding and conveying film; a laminating mechanism, including an adhesive application component 210 and a pressing component 220, the adhesive application component 210 including an adhesive tank 211 and an adhesive roller 212, the adhesive tank 211 containing adhesive liquid, the adhesive roller 212 being disposed above the adhesive tank 211, and the lower part of the adhesive roller 212 being immersed in the adhesive liquid in the adhesive tank 211; the pressing component 220 including a first pressing roller 221 and a second pressing roller 222, the first pressing roller 221 being disposed above the second pressing roller 222, the first pressing roller 221 and the second pressing roller 2 ... Two pressing rollers 222 work together to press the film and paper together to form a composite paper; the slitting and conveying mechanism includes a base 310, a pressing assembly 320 and a cutter 330. The pressing assembly 320 includes a support roller 321 and a pressing roller 322. The support roller 321 is rotatably mounted on the base 310, and the pressing roller 322 is mounted above the support roller 321. The pressing roller 322 is provided with a connecting arm 323. The connecting arm 323 is provided with a first end 324 and a second end 325. The first end 324 is connected to the base 310 through a pivot 326. The second end 325 is connected to a cylinder 327 and is provided with a mounting seat 328. The cutter 330 is mounted on the mounting seat 328; the receiving mechanism is located behind the slitting and conveying mechanism and is used to receive the composite paper.

[0029] During operation, the first feeding assembly 110 feeds and conveys the paper; simultaneously, the second feeding assembly 120 feeds and conveys the film, and the gluing assembly 210 applies glue to the film; then, the pressing assembly 220 presses the film and paper together to form a composite paper; next, the slitting and conveying mechanism slits the composite paper to obtain composite papers of uniform size; finally, the collecting mechanism collects the composite paper. During slitting, the cylinder 327 drives the second end 325 to move, causing the connecting arm 323 to rotate around the pivot 326. At this time, the pressure roller 322 approaches the support roller 321 to press the composite paper together, and the cutter 330 also works to slit the composite paper, thus obtaining composite papers of uniform size. The automatic laminating device of this embodiment uses the pressure roller and support roller 321 to tightly press the composite paper together, thereby avoiding paper misalignment due to the influence of the cutter 330 during cutting, improving the slitting effect, and ensuring product quality.

[0030] Reference Figure 1 and Figure 2 In this design, cylinder 327 is positioned on the base 310 and below the second end 325, with its extension / retraction end hinged to the second end 325. Specifically, cylinder 327 extends to rotate connecting arm 323 around pivot 326, causing the second end 325 to move upward, at which point pressure roller 322 moves away from support roller 321; cylinder 327 retracts to rotate connecting arm 323 around pivot 326, causing the second end 325 to move downward, at which point pressure roller 322 approaches support roller 321 to press the composite paper, and cutter 330 cuts the composite paper. By positioning cylinder 327 below the second end 325, not only can cylinder 327 be concealed, improving overall aesthetics, but the structure can also be made more reasonable and compact, reducing space occupation. It should be noted that the cylinder 327 can also be positioned above the second end 325. When the cylinder 327 extends to drive the connecting arm 323 to rotate around the pivot 326, the second end 325 moves downward. At this time, the pressure roller 322 approaches the support roller 321 to press the composite paper, and the cutter 330 cuts the composite paper. When the cylinder 327 retracts to drive the connecting arm 323 to rotate around the pivot 326, the second end 325 moves upward, and the pressure roller 322 moves away from the support roller 321. Those skilled in the art can make reasonable choices regarding the placement of the cylinder 327 based on actual conditions, and this application does not impose any restrictions on this.

[0031] Furthermore, the base 310 is equipped with a buffer assembly, which includes a buffer pad 311 positioned above the second end 325. The base 310 also includes a fixed seat 312 with an adjusting screw 313, and the buffer pad 311 is connected to the adjusting screw 313. By providing the buffer assembly, the movement of the second end 325 can be restricted, improving operational stability and reliability.

[0032] Reference Figure 1 and Figure 2 In some embodiments of this application, the slitting and conveying mechanism further includes a guiding component 340, which is disposed in front of the pressing component 320 and is used to guide the composite paper. By providing the guiding component 340, the composite paper in front of the pressing component 320 can be clamped and fed, thereby improving the slitting effect and ensuring product quality.

[0033] Reference Figure 1 and Figure 3 The first feeding component 110 includes a first conveyor belt 111 and a feeding part. The discharge end of the first conveyor belt 111 is connected to the composite mechanism. The feed end of the first conveyor belt 111 is provided with a first lifting platform 112. The feeding part is provided at the connection between the first lifting platform 112 and the first conveyor belt 111. The feeding part is used to pick up paper from the first lifting platform 112 and transfer it to the first conveyor belt 111. Specifically, the material handling section includes a transverse unit 113, a first suction cup 114, a second suction cup 115, and a pressure head 116. The transverse unit 113 is provided with a base 117. The first suction cup 114 is elliptical and mounted on the base 117. The first suction cup 114 is used to pick up paper from the first lifting platform 112. The second suction cup 115 is located on the side of the first suction cup 114 close to the first conveyor belt 111. The second suction cup 115 is used to pick up paper from the first suction cup 114 and transfer it to the first conveyor belt 111. The pressure head 116 is located on the side of the first suction cup 114 away from the first conveyor belt 111. The pressure head 116 is used to press the remaining paper on the first lifting platform 112. During operation, the first lifting platform 112 lifts the paper to a set height and adjusts the position of the base 117 via the transverse unit 113. Then, the first suction cup 114 descends to pick up the paper on the first lifting platform 112, waiting for the paper to be conveyed. At the same time, the pressure head 116 descends to pick up the remaining paper on the first lifting platform 112, avoiding the paper picked up by the first suction cup 114, thereby preventing the paper on the first lifting platform 112 from being carried away by the paper conveyed by the second suction cup 115 due to friction, ensuring the paper is transported one by one. Subsequently, the second suction cup 115 takes the paper from the first suction cup 114, while the first suction cup 114 releases the paper, thereby conveying the paper to the first conveyor belt 111 for transport.

[0034] As can be imagined, the base 117 is equipped with a linkage structure, which is a parallelogram structure. The second suction cup 115 is located on the side of the linkage structure near the first conveyor belt 111. The linkage structure rotates around the two pivot points above, causing the second suction cup 115 to move closer to or away from the first suction cup 114. The structure is simple and easy to operate.

[0035] Reference Figure 1 and Figure 4 The second feeding assembly 120 includes an unwinding roller 121 and multiple guide rollers 122. The unwinding roller 121 is provided with a film roll, and the multiple guide rollers 122 are respectively disposed between the unwinding roller 121 and the gluing assembly 210, and between the gluing assembly 210 and the pressing assembly 220 to guide the film. The film roll on the unwinding roller 121 is guided by the guide rollers 122, first passes through the gluing assembly 210 for gluing, and is finally guided to the pressing assembly 220 to be pressed with the paper, thereby obtaining composite paper. The structure is simple and improves work efficiency.

[0036] In this embodiment, the glue tank 211 is equipped with a glue inlet pipe 213, which is equipped with a glue inlet valve 214. The glue inlet pipe 213 is connected to a glue storage tank 215. Furthermore, the glue tank 211 is equipped with a liquid level sensor, which is electrically connected to the glue inlet valve 214. When the liquid level sensor detects that the glue level in the glue tank 211 is lower than a set position, the glue inlet valve 214 opens. At this time, the glue tank 211 is automatically replenished through the glue inlet pipe 213, eliminating the need for manual operation, reducing labor intensity, and improving work efficiency.

[0037] Reference Figure 1 and Figure 4 The receiving mechanism includes a second conveyor belt 410 and a second lifting platform 420. The inlet end of the second conveyor belt 410 is connected to the slitting and conveying mechanism, and the second lifting platform 420 is located at the outlet end of the second conveyor belt 410. The composite paper output from the slitting and conveying mechanism is output via the second conveyor belt 410 and finally received and stacked by the second lifting platform 420, eliminating the need for manual operation and improving work efficiency. Specifically, the second lifting platform 420 descends one level for each composite paper it receives, thereby improving the stability and reliability of the receiving process. It is easy to understand that a baffle is provided at the end of the second lifting platform 420 away from the second conveyor belt 410, which limits the composite paper on the second lifting platform 420, preventing it from detaching and further improving operational stability and reliability.

[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
