Tape quantitative device for express packaging boxes based on the principle of one-way ratchet

Abstract

The invention provides an adhesive tape quantifying device for an express packaging box based on a one-way ratchet wheel principle, and relates to the technical field of carton packaging. The adhesivetape quantifying device comprises a fixed base. A positioning groove is formed in the fixed base, the interior of the positioning groove is movably connected with a locking mechanism, the front faceof the fixed base is movably connected with a rotary disc, the outer side of the rotary disc is movably connected with a check block, the front face of the rotary disc is movably connected with a positioning disc, and the front face of the positioning disc is movably connected with a rotary column. According to the adhesive tape quantifying device for the express packaging box based on the one-wayratchet wheel principle, the rotating angle of the positioning disc each time is consistent, the initial end of adhesive tape is wound around the outer side of the rotary column, as the positioning disc is movably connected with the rotary column, when the positioning disc rotates, the rotary column can synchronously rotate in the same direction, it can be guaranteed that the discharge length ofthe adhesive tape each time is equal, waste of raw materials is avoided, certain production cost is reduced, and meanwhile the situation that the attractiveness of the packaging box is affected due tothe fact that the adhesive tape is too long is avoided.

Description

technical field [0001] The invention relates to the technical field of carton packaging, in particular to a tape quantification device for express packaging boxes based on the principle of a one-way ratchet. Background technique [0002] With the rapid development of the Internet and e-commerce industry, it directly drives other related industries, among which express delivery and logistics are the most prominent. In order to ensure the safety of express delivery during transportation, cartons are generally used for outer packaging. [0003] When using cartons, it is necessary to combine them according to the predetermined pressing groove and fix them with adhesive tape. In order to save costs and increase the timeliness of express delivery, most e-commerce companies will package the express delivery by themselves. In the process of fixing the carton with tape, the problem of too long tape often occurs. On the one hand, due to the high viscosity and softness of the tape, it ...

Problems solved by technology

[0003] When using cartons, it is necessary to combine them according to the predetermined pressing groove and fix them with adhesive tape. In order to save costs and increase the timeliness of express delivery, most e-commerce companies will package the express delivery by themselves. In the process of fixing the carton with tape, the problem of too long tape often occurs. On the one hand, due to the high viscosity and softness of the tape, it is easy to stick together, resulting in waste of materials. On the other hand, too long tape will affect the packaging. The beauty of the rear carton

[0004] In order to solve the above problems, the inventor proposed a quantitative device for adhesive tape for express packaging boxes based on the principle of one-way ratchet, which has the advantage of ensuring that the length of the tape is consistent each time, avoiding the waste of raw materials and saving a certain amount of production costs. At the same time, it avoids the impact on the appearance of the packaging box due to the excessive length of the tape
