[0036] As an example, a pressure-maintaining mechanism can be provided in a film-wrapping device to perform a re-pressure treatment on a workpiece that has been coated with a packaging film. An adhesive layer can be provided on one side of the packaging film, which is used to adhere the other side to the adhesive layer of the side during film-wrapping to form a cylindrical protective structure.

[0037] During the operation of the pressure-keeping mechanism, the workpiece conveying box 11 can hold the workpiece that has been coated, and the workpiece is placed with the side of the adhesive layer of the packaging film facing upward. The pressure-keeping component 2 performs a re-pressure treatment on the adhesive layer of the packaging film adhered to the workpiece to make the adhesive layer adhere more tightly and improve the coating quality.

[0038] In this example, by setting up the workpiece conveying component 1 and the pressure maintaining component 2, the workpiece after the film is coated can be further re-pressurized to ensure that the adhesive layer of the packaging film is firmly bonded, avoiding the loose bonding caused by insufficient viscosity of the adhesive layer or errors in the processing accuracy during coating, and improving the coating quality.

[0040] As an example, Figure 2 As shown, the workpiece conveying assembly 1 further includes at least one slide rail 12 and at least one servo transmission structure 13. The workpiece conveying box 11 is movably connected to the slide rail 12, and the servo transmission structure 13 is mounted on the slide rail 12 and is in transmission connection with the workpiece conveying box 11, and can drive the workpiece conveying box 11 to move along the slide rail 12 in a first direction to below the pressure-maintaining assembly 2, and continue to move along the slide rail 12 in the first direction to the unloading position after the pressure-maintaining assembly 2 completes the pressure-maintaining action, and move along the slide rail 12 to the second direction to reset after all the workpieces in the workpiece conveying box 11 are unloaded, and the first direction and the second direction are two opposite directions.

[0041] In one embodiment, the servo transmission structure 13 includes a servo motor and a transmission hinge; the servo motor and the transmission hinge are assembled on the slide rail 12; the transmission hinge is transmission-connected to the output shaft of the servo motor and the workpiece conveying box 11, and is used to drive the workpiece conveying box 11 to move along the slide rail 12 to the bottom of the pressure maintaining assembly 2 under the drive of the servo motor.

The transmission hinge is connected to the output shaft of the servo motor and the workpiece conveying box 11, and the transmission hinge can drive the workpiece conveying box 11 to move along the slide rail 12 under the drive of the servo motor.

[0043] In one embodiment, the pressure-maintaining assembly 2 includes a pressure-maintaining bracket 21, a pressure-maintaining cylinder 22 and a pressure-maintaining head 23; the pressure-maintaining bracket 21 is arranged above the workpiece conveying assembly 1; the pressure-maintaining cylinder 22 is assembled on the pressure-maintaining bracket 21 in the vertical direction; the pressure-maintaining head 23 is assembled at one end of the pressure-maintaining cylinder 22, and is used to move in the vertical direction under the drive of the pressure-maintaining cylinder 22, and to perform re-pressure treatment on the packaging film attached to the adhesive layer of the packaging film.

[0044] As an example, the pressure-maintaining assembly 2 includes a pressure-maintaining bracket 21, a pressure-maintaining cylinder 22, and a pressure-maintaining head 23.
