Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a special-shaped window pasting machine. Background Art

[0002] The cardboard window pasting machine is an automated mechanical equipment widely used in the packaging industry. The equipment is mainly used to paste transparent films (such as PVC or PET films) on the windows cut out of cardboard or corrugated cardboard to form a product display window.

[0003] However, as the requirements for various product display windows vary, display windows with special edges such as arcs and waves have gradually appeared, such as Figure 1 The one shown is wavy. For display windows with such special-shaped edges, a rectangular transparent film is usually directly covered on the inside. At the same time, in order to pursue the internal aesthetics, a layer of paper is usually covered on the inside of the cardboard to improve the aesthetics. However, due to the presence of the rectangular transparent film, there will be an obvious rectangular bulge on the inside near the display window, affecting the overall aesthetics of the cardboard.

[0004] In order to ensure the beauty of the inner side of the cardboard, the existing technical solution is to cut the transparent film close to the irregular edge to form the same irregular edge to ensure the beauty of the inner side of the cardboard, but this cutting can only rely on manual cutting and pasting, that is, there is no suitable window pasting and cutting equipment. Utility Model Content

[0005] In view of the deficiencies existing in the prior art, the utility model provides a special-shaped window pasting machine, which solves the technical problem that the prior window pasting equipment has no function of cutting transparent films.

The gluing mechanism is located at the lower side of the protective strip, and the protective strip is provided with a groove at the pressing mechanism.

[0010] The technical principle of the utility model is as follows: the cardboard enters the first conveyor belt and is conveyed in the direction of the second conveyor belt. When passing through the reciprocating gluing device, the two sides of the display window of the cardboard are glued in turn, and then the cardboard enters the lower side of the protection strip; when the cardboard moves to the discharging and pressing mechanism, the transparent film is drawn out and pressed and pasted at the gluing places on both sides of the display window. At this time, the transparent films on the other two sides of the display window are on the upper side of the protection strip, and then the cardboard continues to move, the reciprocating cutting mechanism cuts the transparent film, and then the cardboard enters the special-shaped die-cutting device, and the special-shaped die-cutting device cuts the transparent films on the other two sides of the display window into special shapes on the protection strip.

[0011] Then the cardboard enters the second conveyor belt for further conveyance, passes through the gluing mechanism, and is coated with glue on the other two sides of the display window of the cardboard. Finally, at the pressing mechanism, the transparent film contacts the other two sides of the display window of the cardboard through the groove and is adhered to the other two sides of the display window by the pressing mechanism.

[0012] Compared with the prior art, the utility model has the following beneficial effects: by cooperating with the reciprocating gluing device, the material discharging and pressing mechanism, the reciprocating cutting mechanism, the special-shaped die-cutting device and the pressing mechanism, the technical problem that the prior window pasting equipment does not have the function of cutting transparent films is solved.

[0018] Furthermore, the discharging and pressing mechanism includes a storage roller, a front pressing roller and a rear pressing roller, the front pressing roller and the rear pressing roller are arranged horizontally, and the storage roller is arranged on the upper side of the front pressing roller.

[0019] Furthermore, the reciprocating cutting mechanism includes a cutting electric slide rail and a cutting blade installed on the cutting electric slide rail, and the cutting blade is arranged close to the rear pressure roller.

The two sets of die-cutting blades are respectively arranged near the two ends of the roller shaft corresponding to the protection strips, and the die-cutting motor is connected to the roller shaft.

[0022] Furthermore, the width of the two groups of die-cutting blades is less than or equal to the width of the protection strip.

[0023] The protective strip ensures that the die-cutting knife will not damage the cardboard while also ensuring that the transparent film can be cut.

[0024] Furthermore, the lamination mechanism includes a lamination roller and a fluff layer arranged on the lamination roller.

[0025] Furthermore, a common support frame is provided outside the first conveyor belt and the second conveyor belt, and the reciprocating gluing device, the material discharging and pressing mechanism, the reciprocating cutting mechanism, the special-shaped die-cutting device, the gluing mechanism, the pressing mechanism and the protective strip are all arranged on the support frame.
