Description

Technical Field

[0001] The utility model relates to the technical field of packaging box processing, in particular to a device for sticking easy-tear tapes for color-printed packaging boxes. Background Art

[0002] Color printing refers to the technology of printing in batches on the same page with different colors to achieve a color picture effect. The original text, drawings, photos, etc. are transferred to the surface of paper, fabrics, leather and other materials through plate making, inking, pressurization and other processes to copy the original content in batches. In order to improve the aesthetics of the packaging box, the packaging box needs to be pasted with tear tape during processing, so a tear tape pasting device for color printing packaging boxes is required.

[0003] For example, an existing patent (publication number: CN214395617U) discloses a device for pasting easy-tear tape on a color-printed packaging box. By providing a processing component, the easy-tear tape is placed on a mounting frame, and the head end of the easy-tear tape is adsorbed and connected to a suction cup. Two sets of No. 2 electric push rods are started to drive the suction cup to move down and fit closely to the starting pasting position of the packaging box. The suction cup is then closed, and the No. 1 motor is started again to drive the packaging box to move. Therefore, relative movement is formed between the easy-tear tape and the packaging box, so that the easy-tear tape can be pasted synchronously.

[0004] However, the above-designed easy-tear tape pasting device for color-printed packaging boxes still has some disadvantages in practical application: although the easy-tear tape pasting device for color-printed packaging boxes can conveniently paste the packaging boxes, when the suction cup presses the easy-tear tape and cooperates to cut the easy-tear tape, the end of the tape is prone to edge, which makes it impossible for the easy-tear tape to be completely attached to the packaging box, which is not only prone to falling off, but also affects the appearance.

[0005] Therefore, we designed a color-printed packaging box easy-tear tape pasting device to solve the above problems. Utility Model Content

By turning on the driving component, the sliding part can drive the fixing part and the pressing wheel group to move downward, so that the pressing wheel group can be conveniently pressed on the packaging box after the bonding. Then the packaging box is transported along the conveyor. During the transportation, the pressing wheel group rolls on the packaging box, so the damping cylinder with the warped edge on the packaging box can be attached.

By providing a damping cylinder 16, the second spring 14 can rebound slowly, preventing the buffer plate 15 from moving quickly due to the elastic force of the second spring 14, which helps to extend the connection stability between the buffer plate 15 and the fixing member 4.

[0036] Working principle:

[0037] When in use, firstly, the electrical appliances involved in the easy-tear tape pasting device for the color-printed packaging box are all connected to an external power supply. When the easy-tear tape needs to be pasted to the packaging box, first, the packaging box is placed on the conveyor 2, and then the conveyor 2 is turned on to transport the packaging box. Then, when the packaging box is transported to the bottom of the installation roller 22, the cylinder 20 is turned on to make the connecting plate 21 drive the installation roller 22 to descend and abut against the packaging box. As the packaging box is transported, the installation roller 22 can rotate and drive the easy-tear tape 19 to extend and adhere to the top of the packaging box. Then, the electric push rod 23 is turned on in coordination to make the driving end of the electric push rod 23 extend and drive the cutter 24 to descend and cut the easy-tear tape 19, so that the pasting of the easy-tear tape 19 on the packaging box is completed. The packaging box is processed and then continues to be transported. When the packaging box is located at the fixed frame 3, the motor 11 is turned on to make the rotating shaft 9 drive the cam 10 to rotate, so that the cam 10 pushes the slide 6 to stretch the first spring 7 and move downward. During this process, the fixing member 4 can drive the pressing wheel group 5 to move downward, that is, the pressing wheel group 5 can be pressed against the top of the packaging box. The packaging box is transported with the conveyor 2, and the pressing wheel group 5 can roll on the packaging box, so that the damping cylinder 16 of the warped edge of the packaging box can be attached. During the upward process, when the pressing wheel group 5 presses on the packaging box, the second spring 14 will be compressed and shortened, which can play a certain buffering effect when the pressing wheel group 5 presses on the packaging box to prevent the pressing wheel group 5 from pressing and deforming the top of the packaging box.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
