[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Please refer to Figure 1-Figure 3 , an automatic laminating device, which includes a base 1, a top end of the base 1 is fixedly connected to a glue coating component 2, a top center position of the base 1 is fixedly connected to an extrusion component 3, and a top end of the base 1 away from the glue coating component 2 is fixedly connected to a winding and cutting component 4;

[0037] When in use, the adhesive can be placed inside the placement box 7 by flipping the flip cover 8, and then the flip cover 8 is buckled to close the placement box 7 to achieve a closed state, thereby reducing impurities and dust in the air from falling into the inside of the adhesive.

[0038] Then, the adhesive tape is placed on the outside of the first roll 6, and the other end of the adhesive tape is passed through the inside of the squeezing assembly 3 and fixed to the inside of the winding and cutting assembly 4.

[0039] During the process of transmitting the adhesive tape, the first motor 11 can be turned on, and the first motor 11 can drive the adhesive coating roller 10 to rotate between the two second fixed plates 9. At this time, the rotation of the adhesive coating roller 10 can bring the adhesive inside the placement box 7 out of the placement box 7 and apply it to the surface of the adhesive tape. Then, the adhesive tape is laminated through the setting of the extrusion component 3, and then the laminated adhesive tape is cut through the setting of the winding and cutting component 4 to facilitate subsequent operations on the adhesive tape.

[0040] Example 2:

[0041] This embodiment 2 is used to further disclose the specific structure of the extrusion component 3 on the premise of the above embodiment.

[0042] The automatic laminating device provided in Example 1 is further optimized, specifically, Figure 4-Figure 5 As shown, the extrusion assembly 3 includes a first support frame 12, a double-headed motor 13, a first rotating rod 14, a third fixed plate 15 and a fixed rod 16. The first support frame 12 is fixedly connected to the middle position at the top of the base 1, and the double-headed motor 13 is fixedly connected to the top of the base 1, and the double-headed motor 13 is located below the first support frame 12. The output ends on both sides of the double-headed motor 13 are fixedly connected to the first rotating rod 14, and the ends of the first rotating rod 14 away from the double-headed motor 13 pass through the bottom of both sides of the first support frame 12, and are rotatably connected to the bottom of both sides of the first support frame 12. The third fixed plate 15 is fixedly connected to both sides of the first support frame 12, and the two ends of the top of the third fixed plate 15 are fixedly connected to the fixed rod 16.

[0043] The extrusion assembly 3 also includes a first threaded rod 17, a bevel gear set 18, a movable plate 19, a fourth fixed plate 20 and a heating plate 21. The first threaded rod 17 is rotatably connected to the inner side of the third fixed plate 15, and the first threaded rod 17 is arranged to pass through the third fixed plate 15. The end of the first threaded rod 17 located below the third fixed plate 15 is provided with a bevel gear set 18, and the first rotating rod 14 drives the first threaded rod 17 to rotate through the bevel gear set 18. A movable plate 19 is provided on the top of the first support frame 12, and the fourth fixed plate 20 is fixedly connected on both sides of the movable plate 19. The bottom of the fourth fixed plate 20 is threadedly connected to the first threaded rod 17, and the two ends of the bottom of the fourth fixed plate 20 are clearance-fitted with the two fixed rods 16. A plurality of heating plates 21 are fixedly connected to the bottom of the movable plate 19, and the spacing between the plurality of heating plates 21 is equal.

[0044] The extrusion assembly 3 also includes a second roller 22, a sprocket 23, a chain 24 and a second motor 25. A plurality of second rollers 22 are rotatably connected to the bottom of the movable plate 19, and each second roller 22 is located between every two heating plates 21. A rotation groove is opened on one side of the bottom of the movable plate 19.

[0045] Specifically, during the adhesive tape installation process, the double-headed motor 13 can be turned on to drive the two first rotating rods 14 to rotate synchronously. At the same time, the bevel gear set 18 can drive the first threaded rod 17 to rotate synchronously inside the fixed rod 16, thereby enabling the two fourth fixed plates 20 threadedly connected to the first threaded rod 17 to move up and down, thereby enabling the movable plate 19 to move synchronously through the movement of the two fourth fixed plates 20.

[0046] By moving the movable plate 19 upward, the space between the bottom of the movable plate 19 and the top of the first support frame 12 can be expanded, thereby making it easier to pass the adhesive tape through the space between the movable plate 19 and the top of the first support frame 12, thereby facilitating the installation of the adhesive tape.

[0047] After the adhesive tape is installed, the double-headed motor 13 can be controlled to drive the first rotating rod 14 to rotate in the opposite direction, thereby driving the movable plate 19 to move downward and close to the top of the first support frame 12, so that the multiple second rollers 22 at the bottom of the movable plate 19 can be applied to the surface of the adhesive tape;

[0048] By turning on the second motor 25, one of the second rollers 22 can be rotated. At this time, the sprocket 23 of the second roller 22 located inside the rotation groove will rotate synchronously. The chain 24 provided inside the rotation groove can drive the sprockets 23 outside the other second rollers 22 to rotate synchronously, thereby achieving the effect of synchronous rotation of multiple second rollers 22, and realizing the multiple second rollers 22 to press and bond the tape surface at the same time;

[0049] By providing a plurality of second rollers 22, the adhesive tape can be repeatedly applied, thereby reducing the possibility of bubbles and other impurities on the inner side of the adhesive tape affecting the production quality of the adhesive tape;

[0050] At the same time, the heating plate 21 can be controlled to increase the temperature, so that the adhesive on the surface of the tape can be dried quickly, thereby saving the time for the adhesive to dry naturally during the production process of the tape, and further improving the production efficiency of the tape.

The movable right-angle plate 31 is located at the bottom of one end outside the movable groove and is fixedly connected to the electric push rod 32, and the cutting knife 33 is fixedly connected to the bottom of the electric push rod 32.

[0055] Specifically, by turning on the third motor 28, the third roller 27 can be driven to rotate inside the bottom of the second support frame 26, so that the tape can be wound and reeled. When the tape reeling meets the production requirements, the fourth motor 29 can be turned on, and the fourth motor 29 drives the second threaded rod 30 to rotate inside the movable groove, thereby driving the movable right-angle plate 31 to move laterally inside the movable groove.

[0056] At the same time, by turning on the electric push rod 32, the cutting knife 33 can be driven to move downward and contact the surface of the tape. The setting of the cutting knife 33 can cut the tape. At the same time, the second threaded rod 30 drives the movable right-angle plate 31 to move horizontally inside the movable groove, so that the cutting knife 33 can cut from one side of the tape to the other side of the tape, thereby completing the cutting work of the tape, so that the staff can collect the cut tape and carry out subsequent tape production work.
