[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4As shown, a PET packaging sheet roll laminating equipment includes a frame 1, a conveyor belt 2 installed on one side inside the frame 1, and a pressing assembly installed on the top of the frame 1 above the conveyor belt 2. The pressing assembly includes a fixing frame 11, an electric push rod 12 is installed through the top of the fixing frame 11, an installation frame 13 is installed at the output end of the electric push rod 12, and a pressure roller 14 is installed inside the installation frame 13.

[0021] Adjust the extension length of the electric actuator 12 according to the thickness of the sheet. The coated sheet is placed on the conveyor belt 2. When the sheet passes the pressure roller 14, the pressure roller 14 presses the coating onto the surface of the sheet. To improve the pressing effect, multiple pressing components can be set as needed.

[0022] Conveyor belt 2 3 is installed on the other side of the frame 1. A horizontal plate 4 is provided between conveyor belt 1 2 and conveyor belt 2 3. Two through slots are symmetrically opened on the end of the horizontal plate 4 near conveyor belt 1 2. The distance between the two through slots is the same as the width of the sheet. A fixing seat 5 is fixed to the bottom of the horizontal plate 4 on one side of the through slot. A cutting blade 1 6 is installed on the fixing seat 5. A positioning rod 19 is fixed to the top of the horizontal plate 4 on one side of the through slot. A baffle plate 20 is installed on the positioning rod 19. The baffle plate 20 is an arc-shaped plate, and its other end is attached to the cutting blade 1 6.

[0023] Conveyor belt 2 transports the sheet material onto the horizontal plate 4. As the sheet material passes through the cutting blade 6, the excess film on both sides of the sheet is cut off. The cut-off excess material falls through the channel under the action of the baffle plate 20 and into the area below the frame 1. A collection box can be installed under the frame 1 to collect the excess material. To avoid cutting deviations, a guiding mechanism can be installed between the horizontal plate 4 and the conveyor belt 2.

[0024] A mounting bracket 7 is provided above the end of the horizontal plate 4 near the second conveyor belt 3. An electric push rod 8 is installed through the top of the mounting bracket 7. A knife holder 9 is installed at the output end of the electric push rod 8. A cutting knife 10 is installed on the knife holder 9. A cutting groove is provided on the top surface of the horizontal plate 4 below the cutting knife 10. A discharge chute is provided at the end of the horizontal plate 4 near the second conveyor belt 3.

[0025] When the head of the sheet reaches the cutting groove, the electric push rod 8 extends rapidly, causing the cutting blade 10 to cut off the excess material at the head of the sheet. The same method is used to cut off the excess material at the tail of the sheet. The cut-off excess material falls through the discharge chute into the collection below the frame 1.

[0026] The drive assembly includes a movable frame 15 with an upward opening and sleeved on the outside of the frame 1. An active roller 16 is installed inside the movable frame 15, and a motor 17 for driving the active roller 16 to rotate is installed on the outside of the movable frame 15. A limiting strip 18 for limiting the movable frame 15 is provided on the side of the frame 1. A fixing groove is opened on the lower part of the side of the movable frame 15, and the movable frame 15 is fixed to the frame 1 by bolts.

[0027] The installation height of the movable frame 15 is adjusted according to the thickness of the sheet. The motor 17 drives the active roller 16 to rotate. The active roller 16 at the first 2 of the conveyor belt generates a pushing force on the sheet in the direction of the horizontal plate 4. The arrangement of two active rollers 16 is conducive to the complete cutting of the sheet.

[0028] In practical use, the coated sheet is placed on conveyor belt 2. When the sheet passes the pressure roller 14, the pressure roller 14 presses the coating onto the surface of the sheet. Conveyor belt 2 transports the sheet to the horizontal plate 4. When the sheet passes the cutting blade 6, the excess coating on both sides of the sheet is cut off. When the head or tail of the sheet reaches the cutting groove, the electric push rod 8 extends rapidly, causing the cutting blade 10 to cut the excess material at the head or tail of the sheet, thereby achieving the cutting of excess material around the edges of the sheet.
