[0026] Example 1

[0027] like Figures 1-3As shown, this utility model proposes a paper printing surface laminating machine, including an operating table 1, a movable plate 8, a slide bar 11, a chuck 13, a guide wheel 14, a drive assembly, and a laminating mechanism. A paperboard conveying assembly is installed on the operating table 1, comprising a transmission roller 2, a conveyor belt 3, and a motor A4. Both transmission rollers 2 are rotatably connected to the operating table 1, and are parallel to the slide bar 11. The conveyor belt 3 drives and connects the transmission rollers 2 on both sides. The motor A4 is connected to the operating table 1, and its output end is connected to one of the transmission rollers 2. A vertical plate A6 and a vertical plate B7 are respectively installed on both sides of the conveying assembly on the operating table 1. An upward-facing slot B71 is provided on the vertical plate B7. The movable plate 8 is rotatably connected to the vertical plate A6, and a mounting shaft 9 is rotatably connected to the movable plate 8. The end of the mounting shaft 9 away from the movable plate 8 is inserted into the slot B71. The two ends of the slide rod 11 are connected to the vertical plate A6 and the vertical plate B7, respectively. Two clamping plates 12 are symmetrically arranged on the slide rod 11 and slidably connected to it. Both clamping plates 12 are parallel to the vertical plates A6 and B7. The top of the clamping plate 12 is provided with an upward-opening slot C121, and the mounting shaft 9 is inserted into the slot C121. Two chucks 13 are rotatably connected to the corresponding clamping plates 12. The chuck 13 is provided with a slot D131, and the mounting shaft 9 is inserted into the slot D131 and coaxial with the chuck 13. A counterweight is provided on the arc surface of the chuck 13 at the end away from the slot D131. Two sets of guide wheels 14 are rotatably connected to the corresponding clamping plates 12. The distance between the guide wheels 14 on both sides is the same as the distance between the chucks 13. The bottom surface of the guide wheels 14 is slidably connected to the upper surface of the conveyor belt 3. The drive assembly includes a bidirectional lead screw 10 and a motor B15. The two ends of the bidirectional lead screw 10 are rotatably connected to the vertical plate A6 and the vertical plate B7, respectively. The bidirectional lead screw 10 passes through the clamping plates 12 on both sides, and the clamping plates 12 on both sides are screwed to the corresponding ends of the bidirectional lead screw 10. The body of the motor B15 is connected to the vertical plate B7, and the output end of the motor B15 is connected to the end of the bidirectional lead screw 10. The coating mechanism includes a support 16, guide rollers A17 and B18, a carriage A19, a heating roller 20, a carriage B21, a cutter 22, hydraulic cylinders A23 and B24. The support 16 is connected to the operating table 1. Guide rollers A17, B18, A19, and B21 are sequentially arranged on the support 16 along the direction from the feed end to the discharge end of the conveying assembly. Both carriages A19 and B21 are slidably connected to the support 16. The heating roller 20 is rotatably connected to carriage A19, and a flexible heat-conducting sleeve coaxial with it is fitted around the heating roller 20. The cutter 22 is connected to carriage B21. Hydraulic cylinder A23 is connected to the support 16 and drives carriage A19 and heating roller 20 to rise and fall. Hydraulic cylinder B24 is connected to the support 16 and drives carriage B21 and cutter 22 to rise and fall. In operation, the coating mechanism coats and automatically cuts the sheet material conveyed by the conveying assembly.

[0028] In this embodiment, when replacing the film roller, motor B15 is first started. Motor B15 drives the bidirectional lead screw 10 to rotate in the opposite direction, causing the clamping plates 12 on both sides to move away from each other. At this time, the chuck 13 no longer presses against the current film roller. Under the action of the counterweight, the chuck 13 automatically rotates until the opening of the slot D131 faces upward. At this time, the mounting shaft 9 can be lifted upward. The operator removes the old film roller and puts on a film roller that is compatible with the width of the cardboard that needs to be laminated. Then, the mounting shaft 9 is lowered so that it is inserted into the slot B71. At the same time, the mounting shaft 9 automatically inserts into the slots C121 and D131. Then, motor B15 is started to drive the bidirectional lead screw 10 to rotate in the forward direction. The clamping plates 12 on both sides move closer to each other until the chucks 13 on both sides are in contact with both ends of the film roller. The mounting shaft 9, chuck 13 and film roller are coaxial. Then, the end of the film is pulled so that it passes under the guide roller A17, then over the guide roller B18, and finally passes under the heating roller 20. When the film roller is feeding, the chuck 13 rotates with the film roller and the mounting shaft 9, without obstructing the feeding of the film roller. When the cardboard on the conveyor belt 3 passes through the channel between the guide wheels 14, the cardboard is automatically aligned and centered under the guidance of the guide wheels 14. When the cardboard is conveyed to the bottom of the heating roller 20, it presses against the film with the heating roller 20. As the cardboard moves, the film automatically adheres to the surface of the cardboard under the downward squeezing force of the heating roller 20. After the cardboard leaves the heating roller 20, when the tail of the cardboard passes the cutter 22, the hydraulic cylinder B24 drives the cutter 22 to slide down and cut the film.

[0029] Example 2

[0030] like Figure 1 As shown, the paper printing surface laminating machine proposed in this utility model, compared with Embodiment 1, has a support plate 5 installed on the operating table 1. The support plate 5 is located inside the conveyor belt 3 and is slidably connected to the lower surface of the upper load-bearing section of the conveyor belt 3. A cavity is provided inside the support plate 5, and heat transfer oil is stored in the cavity. A cooler for adjusting the temperature of the heat transfer oil is installed on the support plate 5. The cooler includes, but is not limited to, a semiconductor cooler, and the cold end of the semiconductor cooler is attached to the surface of the support plate.

[0031] In this embodiment, the support plate 5 supports the conveyor belt 3, and the paperboard is kept flat when the heating roller 20 and the cutter 22 apply pressure to it. The structure of the cooler reduces the surface temperature of the support plate 5, and avoids the high heat generated by the sliding friction between the conveyor belt 3 and the support plate 5, which could cause the conveyor belt 3 to deform or be damaged.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
