[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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 scope of protection of the present utility model.

[0023] like Figure 1-4 As shown, a multi-purpose laminating machine includes a support frame, which consists of a support frame 1 and a support frame 2. The support frame 1 and the support frame 2 are connected at the middle by a worktable 3. A lower pressure film roller 4 is arranged on the rear side of the worktable 3. A film roller 13 and an upper pressure film roller 5 with a lifting mechanism are arranged on a support frame above the lower pressure film roller 4. A paper roller 7 is arranged on the lower front side of the support frame, and a drawing roller 14 is arranged on the lower rear side of the support frame. The worktable 3 is a hollow shell structure, and a panel suction cup is arranged inside the worktable 3. The air structure includes a driven wheel 10 fixedly connected to one end of each of the film roller 13, painting roller 14, and paper roller 7. A locking element 9 is provided at the bottom end of each driven wheel 10. One end of each of the film roller 13, painting roller 14, and paper roller 7 is hinged to one side of the bracket using a spherical bearing. During installation and removal, only the other end needs to be removed, which is very convenient and quick. The locking element 9 at the other end limits the film roller 13, painting roller 14, and paper roller 7 to the mounting groove of the frame. The ventilation holes 31 are drilled using a laser array, which takes into account both adsorption force and surface flatness.

[0024] like Figure 1 and Figure 4 As shown, the workbench 3 includes an upper plate 301, a lower plate 302, and a grooved plate 303. The upper plate 301 and the lower plate 302 are integrally connected by an arc plate 304, and the lower plate 302 and the grooved plate 303 are integrally formed. A plurality of ventilation holes 31 are arranged in an array on the upper plate 301. A plurality of mounting boxes 32 are arranged along a straight line on the lower side of the upper plate 301. Each mounting box 32 is provided with a fan 33. The lower side of the mounting box 32 is provided with a first ventilation opening. The lower side of the grooved plate 303 is provided with a second ventilation opening corresponding to the first ventilation opening.

[0025] Specifically, the upper plate 301 and the lower plate 302 are integrally connected by an arc-shaped plate 304 using stamping or casting processes. The arc-shaped plate 304 is designed as a continuous and smooth curved structure (such as a semi-circle or parabola), which enhances the overall rigidity and avoids stress concentration. The ventilation holes 31 are arranged in a rectangular or honeycomb array on the surface of the upper plate 301, with the hole spacing greater than 1.5 times the hole diameter to ensure uniform airflow. The mounting box 32 is formed by bending sheet metal and is fixed to the lower side of the upper plate 301 with bolts. The mounting box 32 has a reserved fan mounting slot inside and a first ventilation opening. The fan 33 is an axial flow fan, fixed inside the mounting box 32 with screws. The power cord is led out from a reserved hole on the side of the box and connected to an external control module. The second ventilation opening is opened at the bottom of the channel plate 303, aligned with the position of the first ventilation opening, with a diameter or width slightly larger than the first ventilation opening to ensure unobstructed airflow.

[0026] Airflow path within mounting box 32: During air intake, external air enters the workbench 3 through the ventilation holes 31 of the upper plate 301, creating a local negative pressure. After the fan 33 starts, it draws air into mounting box 32 through the ventilation holes 31 and blows it downwards through the first vent into the air duct formed by the channel plate 303. The gas is discharged through the second vent at the bottom of the channel plate 303, avoiding airflow swirl that could interfere with the adsorption effect. The negative pressure adsorbs the drawing paper, preventing displacement or wrinkling during the lamination process, which is especially suitable for thin or flexible materials.

[0027] like Figure 1 and Figure 3 As shown, the locking member 9 includes a hydraulic cylinder 91 fixedly connected to the lower side of the driven wheel 10, a connecting block 92 fixedly connected to the output end of the hydraulic cylinder 91, and an abutment block 93 hinged to the lower end of the driven wheel 10. In the initial state, one end of the abutment block 93 is hinged to the bracket, and the other end of the abutment block 93 serves as a free end abutting against the connecting block 92 (at this time, the abutment block is in an inclined state). The abutment block 93 has an arc-shaped groove on the side facing the driven wheel 10. When the hydraulic locking element 9 is released (i.e., the hydraulic cylinder 91 retracts and the abutment block 93 disengages from the driven wheel 10), the paper roll / canvas is manually loaded, and the locking element 9 is pressed in (i.e., the hydraulic cylinder 91 extends and the abutment block 93 presses in the driven wheel 10). During use, simply opening and closing the locking element 9 is sufficient to limit the position of the film roller 13, the painting roller 14, and the paper roller 7 at this end, saving time spent installing and disassembling the film roller 13, the painting roller 14, and the paper roller 7, and greatly improving the laminating efficiency.

[0028] The multi-purpose laminating machine provided by this utility model is suitable for two working modes:

[0029] When a backing paper film is present: the backing paper film roller is mounted on the film roller 13, the backing paper roller is mounted on the take-up backing paper roller 15, and the drawing roller is mounted on the paper roller 7; the drawing paper on the drawing roller is guided by the guide roller on the front side of the work platform 3 and laid on the worktable 3, then passes between the upper pressure film roller 5 and the lower pressure film roller 4. After the backing paper in the backing paper film on the backing paper film roller separates from the film, the film passes between the upper pressure film roller 5 and the lower pressure film roller 4 and covers the upper side of the drawing paper. The film is covered on the drawing paper by the cooperation of the upper pressure film roller 5 and the lower pressure film roller 4. During this process, the flatness of the drawing paper is maintained by the operation of the fan 33. The backing paper is wound around the guide roller on the upper side of the film roller 13 and then wound onto the take-up backing paper roller 15. After the film is covered, it is wound onto the drawing roller 14 on the rear side. After being wound to a certain length, it is cut to a certain length by a cutter (not shown in the figure due to existing technology).

[0030] When there is no backing paper: The film roller is installed on the upper end of the film roller 13, and the drawing roller is installed on the paper roller 7; the drawing paper on the drawing roller is guided by the guide roller on the front side of the work platform 3 and laid on the worktable 3, and then passes between the upper pressure film roller 5 and the lower pressure film roller 4. The film on the film roller passes between the upper pressure film roller 5 and the lower pressure film roller 4 and covers the upper side of the drawing paper. The film is covered on the drawing paper by the cooperation of the upper pressure film roller 5 and the lower pressure film roller 4. During this process, the fan 33 keeps the drawing paper flat. The backing paper is wound around the guide roller on the upper side of the film roller 13 and then wound onto the backing paper roller 15. After the film is covered, it is wound on the drawing roller 14 on the rear side. After being wound to a certain length, it is cut to a certain length by a cutter (not shown in the figure because of the existing technology).
