Description

Technical Field

[0001] The present application relates to the field of laminating devices, and in particular to a laminating device for an inkjet printer. Background Art

[0002] An inkjet printer is a software-controlled, non-contact device used to mark products. It is primarily used to print images, text, and numbers on various surfaces. The printer operates by deflecting charged ink particles through a high-voltage electric field, achieving precise printing. To protect the images, text, and numbers printed on the surface of an object from scratches during transportation, the surface must be coated.

[0003] The Chinese utility model with publication number CN219564139U discloses a film laminating device for color-printed products, including a base, a lifting base slidably connected to the base, a mold groove is provided on the lifting base, four support rods are fixedly connected to the base, and the four support rods are commonly fixedly connected to a top base, a top groove is provided on the top base, an annular blade is fixedly connected to the inside of the top groove, a film pulling assembly is fixedly connected to the base, and a lifting assembly is provided inside the base. By setting the lifting assembly, the utility model can place the product into the mold groove, and step on the pedal to make the lifting base and the color-printed product in the mold groove move upward together. During this process, the color-printed product will contact the plastic film, and the film will be tightened and cover the surface of the product. After that, the annular blade will cut a piece of film with the same shape as the product on the plastic film, and the cut film will cover the surface of the product. At this time, the pedal can be released to take the film-covered product out of the mold groove.

[0004] With respect to the above-mentioned related technologies, the inventors believe that after the plastic film is cut, it is easy to break during the film drawing process and the surface of the plastic film is easy to become uneven during the subsequent lamination process, thereby reducing the lamination efficiency and quality. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a laminating device for an inkjet printer.

[0006] The present application provides a laminating device for an inkjet printer, which adopts the following technical solution:

[0007] A laminating device for an inkjet printer comprises a base, a lifting platform arranged on the base, a top seat arranged on the top of the lifting platform and a mounting rod arranged on the base, the mounting rod is connected to the top seat, a top groove is provided on the top seat, an annular blade is provided inside the top groove, an unwinding assembly and a rewinding assembly for conveying plastic film are provided on the base, a tensioning assembly and a moving assembly are provided on the top seat; the number of the tensioning assemblies is two, the tensioning assembly close to the rewinding assembly is fixedly arranged on the top seat, the tensioning assembly close to the unwinding assembly is connected to the moving assembly, and the moving assembly drives the tensioning assembly to move along the length direction of the plastic film.

[0008] By adopting the above technical solution, the lifting platform drives the object to rise, and the tensioning assembly tensions the plastic film. During the object's ascent, the plastic film is moved toward the annular blade, which cuts the plastic film so that it covers the surface of the object. The tensioning assembly improves the lamination quality. The lifting platform drives the lamination-coated object to descend, and the winding and unwinding assemblies drive the plastic film to move. The moving assembly drives the tensioning assembly to move. The tensioning assembly close to the unwinding assembly clamps the plastic film, while the tensioning assembly away from the unwinding assembly loosens the plastic film. This leaves the plastic film between the winding and tensioning assemblies in an untensioned state, and the plastic film between the unwinding and tensioning assemblies in a tensioned state. This reduces the phenomenon of the cut portion of the plastic film breaking during movement, thereby improving lamination efficiency.

[0009] Preferably, the tensioning assembly includes a fixed splint, a movable splint and a first electric telescopic rod, one end of the first electric telescopic rod is connected to the fixed splint, and the other end is connected to the movable splint, and the plastic film passes through the gap between the fixed splint and the movable splint.

[0011] Preferably, both the fixed splint and the movable splint are provided with anti-slip pads.

[0012] By adopting the above technical solution, the provision of the anti-slip pad reduces the phenomenon of damage to the plastic film during the clamping process, thereby improving the quality of the plastic film and further improving the lamination quality.

[0014] By adopting the above technical solution, the first motor drives the reciprocating screw to rotate, the reciprocating screw drives the slider to slide in the limiting slide groove, and the slider drives the fixed splint to move, thereby reducing the force on the cut part of the plastic film, thereby reducing the phenomenon of the plastic film breaking at the cut part.

The limiting assembly includes a third support rod and a plurality of limiting rollers provided on the base, and the plurality of limiting rollers are rotatably connected to the third support rod, and the plastic film passes through the gaps between the plurality of limiting rollers.

[0020] By adopting the above technical solution, the limiting component limits the plastic film between the unwinding component and the winding component, so that the position of the plastic film remains consistent during the laminating process, thereby making the plastic film subjected to consistent force during the laminating process, thereby improving the laminating quality.

[0021] Preferably, a tension adjustment assembly is provided on the base, and the tension adjustment assembly is located between the limit assembly and the unwinding assembly. The tension adjustment assembly includes a second electric telescopic rod, a mounting block and an adjusting roller, one end of the second electric telescopic rod is connected to the base, and the other end is connected to the mounting block, and the adjusting roller is rotatably connected to the mounting block.

[0022] By adopting the above technical solution, during the unwinding and rewinding process, the diameter of the plastic film on the rewinding roller and the unwinding roller changes, thereby causing the tension of the plastic film to change. The tension adjustment component changes the height of the adjustment roller through the second electric telescopic rod, thereby adjusting the tension of the plastic film, thereby improving the lamination quality.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The tensioning component tensions the plastic film during the laminating process, thereby improving the laminating quality;
