[0033] The upper surface of the laminating and cutting frame 1 is provided with an auxiliary roller group 11 corresponding to the pressing and cutting component 8. The pressing and cutting component 8 and the auxiliary roller group 11 are used together to shape and cut the laminated product. Two brackets 12 are fixedly connected to the right side of the upper surface of the laminating and cutting frame 1, and the two brackets 12 are installed with GAG feeding rollers 13 and laminating feeding rollers 14.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, the fixed frame 4 includes two vertical plates 401, and the top ends of the two vertical plates 401 are fixedly connected to the horizontal plates 402. The up and down adjustment components 5 include an electric push rod 501 fixedly connected to the horizontal plates 402. The telescopic end of the electric push rod 501 is fixedly connected to the movable plate 6. The front and rear sides of the lower surface of the horizontal plate 402 are fixedly connected with guide rods 502. The bottom ends of the guide rods 502 pass through the guide holes provided in the movable plate 6 and are fixedly connected to the upper surface of the laminating and cutting frame 1. The guide rods 502 are slidably connected to the movable plate 6. With the cooperation of the guide rods 502 and the guide holes, the movement of the movable plate 6 can be guided to prevent the movable plate 6 from being offset during the movement.

[0035] The electric push rod 501 is activated to extend and drive the movable plate 6 to move downward along the guide rod 502. During the movement, the movable plate 6 can drive the cutting knife holder 10 and the cutting knife 804 to move downward through the reset assembly 7, so that the cutting knife 804 cuts the GAG ​​roll.

[0036] like Figure 2 and Figure 6 As shown, in this embodiment, the reset assembly 7 includes two slide bars 701 fixedly connected to the upper surface of the cutting tool holder 10, the top of the slide bar 701 passes through the movable plate 6 and is fixedly connected to the limiting block 702, the outer surface of the slide bar 701 is provided with a spring 703, and the slide bar 701 is slidably connected to the movable plate 6.

[0037] After the roller 803 contacts the GAG ​​coil, due to the presence of the bottom drag roller 1102, the cutting tool holder 10 can drive the slide bar 701 to slide upward and compress the spring, thereby providing a buffer and better contact stability.

[0038] like Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the pressing and cutting assembly 8 includes a central axis 801, and a plurality of cylinders 802 are fixedly connected to the outer surface of the central axis 801. The outer surface of the cylinder 802 is rotatably connected to a roller 803 through a bearing. A cutting knife 804 with different angles is installed between two adjacent cylinders 802. The central axis 801 includes two rotating axes 8011. The two rotating axes 8011 are rotatably connected to two fixed boxes 9 through bearings. A limiting disk 8012 is fixedly connected to the side of the rotating axis 8011 close to the fixed box 9. The cylinder 802 and the cutting knife 804 are sleeved on the outer surface of the rotating axis 8011 and fixedly connected by a nut 8013. A through groove 8014 is provided on the side close to the two rotating axes 8011. A connecting rod 8015 is provided in the through groove 8014 and fixedly connected by a bolt 8016.

[0039] By setting up multiple cutting knives 804, the cutting knives 804 are provided with through holes, are sleeved on the outer surface of the central shaft 801, and are fixed by the cylinder 802 and the nut 8013, so as to facilitate the cutting of coils of different sizes. At the same time, when the cutting knives 804 are not sharp, the bolts 8016 are unscrewed and the connecting rod 8015 is removed, and then the nut 8013 is loosened, and the cutting knives 804 can be easily removed for replacement.

[0040] In order to allow the roller 803 to rotate freely without friction with the cutting blade 804, Figure 7 As shown, in this embodiment, the cylinder 802 is larger than the width of the roller 803 , and the cutting blade 804 protrudes from the outer surface of the roller 803 .

[0041] like Figure 2-5 As shown, in this embodiment, the front side of the rotating shaft 8011 extends to the inside of the fixed box 9 and is fixedly connected to a worm wheel 8017, the right side of the left fixed box 9 is fixedly connected to a worm 8018, the right side of the worm 8018 is fixedly connected to a handle 8019, the left side of the worm 8018 is located inside the fixed box 9 and is meshed with the worm wheel 8017, the front side of the rotating shaft 8011 extends to the outside of the fixed box 9 and is fixedly connected to a pointer 8020, and the front side of the fixed box 9 is provided with a scale line 8021 corresponding to the pointer 8020

[0042] When cutting is required, turn the handle 8019 to drive the worm 8018 to rotate. During the rotation process, the worm 8018 cooperates with the worm wheel 8017 to drive the rotating shaft 8011, the pointer 8020 and the center axis 801 to rotate. During the rotation process, the center axis 801 can drive the cylinder 802, the roller 803 and the cutting knife 804 to rotate. At this time, observing the position of the pointer 8020 on the scale line 8021 can make the appropriate cutting knife 804 face downward, so as to better process products of different sizes.

[0043] like Figure 4 and Figure 6 As shown, in this embodiment, the auxiliary roller group 11 includes two fixed seats 1101 fixedly connected to the upper surface of the laminating and cutting frame 1, and a drag roller 1102 is rotatably connected between the two fixed seats 1101 through a bearing. The outer surface of the drag roller 1102 is provided with a cutting groove 1103 corresponding to the cutting knife 804.

[0044] When the cutting blade 804 cuts the GAG ​​coil, it is located in the cutting groove 1103. At this time, the roller 803 contacts the GAG ​​coil, so that the roller 803 and the drag roller 1102 rotate during cutting, pressing the two sides of the coated product.

[0045] According to the technical solution provided by the present invention, a material receiving assembly is arranged on the left side of the film coating and cutting frame 1. The GAG ​​coil and film material can be pulled out from the GAG ​​feeding roller 13 and the film coating feeding roller 14 on the right side, and then pass through the laminating hot pressing roller group 3 and the re-pressing roller group 2 for film coating, and are wound up in cooperation with the material receiving assembly. At this time, the GAG ​​coil and film material are located between the pressing and cutting assembly 8 and the auxiliary roller group 11, and the drag roller 1102 is in contact with the lower surface of the GAG ​​coil. When cutting is required, the handle 8019 is turned to drive the worm 8018 to rotate. During the rotation process, the worm 8018 cooperates with the worm wheel 8017 to drive the rotating shaft 8011, the pointer 8020 and the central shaft 801 to rotate. During the rotation, the central axis 801 can drive the cylinder 802, the roller 803 and the cutting knife 804 to rotate. At this time, observing the position of the pointer 8020 on the scale line 8021 can make the appropriate cutting knife 804 face downward, and then start the electric push rod 501 to extend and drive the movable plate 6 to move downward along the guide rod 502. During the movement, the movable plate 6 can drive the cutting knife holder 10 and the cutting knife 804 to move downward through the reset component 7 until the cutting knife 804 cuts the GAG ​​coil. At this time, the roller 803 contacts the GAG ​​coil, so that when cutting, the roller 803 and the drag roller 1102 rotate, which will press the two sides of the coated product, making the cutting more neat.

[0046] All technical features in this embodiment can be freely combined according to actual needs.

[0047] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
