Description

CROSS REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202110224923.5, filed on Mar. 1, 2021, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to the field of pasting of adhesive tapes, mainly relates to the automatic pasting of an adhesive tape, and particularly relates to a cantilever type plane automatic adhesive tape pasting device.

BACKGROUND ART

Various packaging containers and products often need to be sealed or pasted with adhesive tapes on the surfaces or inner surfaces, which is often manually operated. During manual operation, an adhesive tape roll is generally directly held by the hand to tear off the adhesive tape head, then the adhesive tape is pasted and manually cut at the same time when a pasting position is found, it is often necessary to look for the position of the adhesive tape head during operation, the entire operation process is small in difficulty but has large labor demand, resulting in a great effect on the production efficiency.

To avoid the defect of repeatedly looking for the position of the adhesive tape head and to facilitate the cutting of the adhesive tape, there are various types of handheld box sealers on the market, the principle of which is basically to install an adhesive tape roll in the box sealer, to paste the adhesive tape by holding the box sealer with the hand after pulling out the adhesive tape head, and to break the adhesive tape using a cutting knife at the end part of the box sealer after the pasting is finished, thus completing the box sealing process. Compared to manual sealing, the handheld box sealer has made a great progress: firstly, it is no longer necessary to look for the adhesive tape head frequently; secondly, it is more convenient to cut off the adhesive tape, and thirdly, it can be operated with one hand. However, a starting position of the device during box sealing still needs to be manually controlled, and it is difficult to operate in the container.

To further improve the efficiency of box sealing, an adhesive tape seal pasting mechanism (Document 1: Chemical Industry Press, Practical Manual of Packaging Machinery edited by Li, Lianjin, 2019.11.p559) has emerged. Automatic adhesive tape pasting on the top and the bottom can be directly completed when a packaged rectangular (carton) container passes through the mechanism, and the mechanism is suitable for large-scale adhesive tape seal pasting of the rectangular packaging container. However, during the work of the mechanism, the adhesive tape pasting process can only be conducted by the pushing of the rectangular container, that is, the device can only be applied to the adhesive tape pasting of a rigid rectangular container, and is not suitable for independent pasting on the surface plane of an item and is not suitable for pasting on the inner surface of the container.

In actual production, adhesive tapes often need to be pasted to specified positions of outer or inner planes of items according to a certain length in a large batch of products, at the moment, the mechanism in document 1 cannot be used. Although a handheld box sealer can be used, the defects that the starting position needs to be manually controlled, the length of the adhesive tape pasted by one person is limited, inner pasting is difficult and the like still exist, and pure manual operation is low in efficiency and high in cost. Therefore, to paste the adhesive tape on the specific position of the plane of the item according to a certain length rapidly and efficiently, an automatic adhesive tape pasting device capable of being applied to inner and outer surfaces needs to be developed.
