Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detection equipment, and particularly relates to a cigarette packaging box adhesive testing device. BACKGROUND

[0002] With the development of society, various industries have also developed vigorously. With the improvement of people's living standards, consumers not only pay attention to the taste when smoking, but also pay more and more attention to the packaging box of cigarettes. Therefore, while the tobacco industry pays attention to the taste of cigarettes, the outer packaging of cigarettes is also paid more and more attention.

[0003] The packaging box of cigarettes is generally divided into hard boxes and soft boxes. The hard box has a crease line at the folding place of the trademark paper, which facilitates the folding of the trademark paper by the equipment. The soft box trademark paper does not have a crease line. Although the forms of the trademark papers of the two are different, the cigarette boxes are shaped by adhesive. However, in the process of forming the cigarette package, sometimes the matching of the glue and the trademark paper is not good, the amount of glue is not grasped, or the extrusion force is not enough, etc. Factors such as the above cause the adhesive surface of the cigarette box to be not firmly bonded. Therefore, after the cigarette packaging box is formed, the workers will randomly take out several cigarette boxes and tear along the adhesive position. If the two layers of trademark papers are easily separated when being torn, the paper surface of the two adhesive positions is relatively complete, which indicates that the bonding is not firm. The adhesive surface of the paper of the two adhesive positions is damaged in the tearing process, which indicates that the bonding is firm. However, this way of relying on manual tearing and judging whether the bonding is firm is not objective and cannot be quantified. Different people have different forces and ways when tearing, which leads to the result of the judgment not being accurate enough. SUMMARY

When the connecting plate 51 and the first unfolding packaging box 57 are driven to move to the left by the telescopic motor 31, that is, when the first unfolding packaging box 57 and the second unfolding packaging box 58 are about to be separated, the connecting plate 51 drives the locking assembly to move to the left, thereby pulling the spring 63. The tension sensor 62 records the separation tension of the first unfolding packaging box 57 and the second unfolding packaging box 58. Then, whether the two bonding surfaces are complete when being torn is observed. If the two bonding surfaces are relatively complete when being torn, it indicates that the two packaging boxes are not firmly glued. If the two bonding surfaces are not complete and are damaged when being torn, it indicates that the two packaging boxes are firmly glued. Through the tension reading of the tension sensor 62, the tension required to tear the two packaging boxes which are firmly glued can be obtained, so as to objectively display the gluing condition of the cigarette packaging box. Through the pressure when the two packaging boxes are bonded and the tension when the two packaging boxes are torn, the relationship among the glue, the pressure and the tension can be obtained.

Through the installation of the rubber pad 652, the abrasion between the arc-shaped plate 651 and the second connecting pipe 64 during long-term use is avoided. The third bolt 655 is screwed on the first connecting block 653 and the second connecting block 654. The end of the third bolt 655 is screwed with a nut. The arc-shaped plate 651 and the second connecting pipe 64 are fastened by screwing the nut on the third bolt 655.

[0045] The control panel 56 is fixedly installed on the mounting plate 50 and is electrically connected with the telescopic motor 31, the pressure sensor 59 and the tension sensor 62.

The control panel 56 can display the values of the pressure sensor 59 and the tension sensor 62 during testing, which is convenient for testers to intuitively observe.

[0046] In this embodiment, before use, the unfolded cigarette packaging box is placed in the first placing box 41. Then two unfolded packaging boxes are taken out from the first placing box 41. The second unfolded packaging box 58 is glued by a special small-size glue dispenser. The electric heater is turned off, so that the mounting plate 50 and the two third clamping plates 53 are exposed. The second unfolded packaging box 58 is placed between the mounting plate 50 and the two second clamping plates 53. The sleeve pipe 55 is moved, so that the two second clamping plates 53 clamp the second unfolded packaging box 58.

The first unfolded packaging box 57 is placed between the connecting plate 51 and the two first clamping plates 52. The second bolt 54 is rotated, so that the position of the first clamping plate 52 is fixed. Thus, the two first clamping plates 52 clamp the first unfolded packaging box 57.

[0047] The telescopic motor 31 is started by the control panel 56, the pressure sensor 59 and the tension sensor 62, the telescopic motor 31 works, drives the connecting plate 51 to move to the mounting plate 50 direction, makes the first unfolding packaging box 57 and the second unfolding packaging box 58 close, and the first unfolding packaging box 57 and the second unfolding packaging box 58 are bonded by glue, at this time, the pressure when the two are bonded can be directly observed through the control panel 56, then the electric heater is started, the heating pipe is adjusted to the appropriate gear through the gear controller, the bonding place of the first unfolding packaging box 57 and the second unfolding packaging box 58 is heated, the heating time is controlled, and the heating time is about 1-2 seconds, after the heating is completed, the electric heater is closed, the telescopic motor 31 works again, drives the first unfolding packaging box 57 and the second unfolding packaging box 58 to tear, the tension when the two are torn can be directly observed through the control panel 56, and whether the bonding surface is intact can be observed on the bonding surface of the first unfolding packaging box 57 and the second unfolding packaging box 58, if the bonding is not firm, the bonding surface is not complete, and the bonding is firm.

[0048] When the bonding is not firm, the sleeve 55 is reversely rotated, the linkage rod 552 is moved through the sleeve 55, the linkage rod 552 drives the second clamping plate 53 to move, the second unfolding packaging box 58 is loosened, the first clamping plate 52 is loosened by reversely rotating the second bolt 54, the first unfolding packaging box 57 is taken out, the first unfolding packaging box 57 and the second unfolding packaging box 58 are placed in the second placing box 42, two new unfolding packaging boxes are taken out from the first placing box 41, and the above steps are repeated until the bonding surface of the two is not complete.
