Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field especially relates to a counting packing machine. BACKGROUND

[0002] The packing machine is also called a bundling machine, a strapping machine or a bundling machine, which is used for bundling products or packaging pieces by using bundling tapes, and then tightening and combining the two ends by heat fusion bonding. The function of the packing machine is to reinforce the packaging articles, so that the articles are not scattered due to loose bundling during the handling process and storage.

[0003] Before the packing machine packs, the pre-tape feeding assembly will feed the tape into the tape warehouse in advance, so that the tape can be directly taken from the tape warehouse during packing. In the prior art, the pre-tape feeding assembly does not measure the length of the tape during feeding, so that there are many tapes stored in the tape warehouse. Generally, a mechanism for detecting the weight of the tape is arranged below the tape warehouse to roughly estimate the amount of the tape, so as to prevent the tape warehouse from being filled with tapes. For example, the patent number 201120544603.X is a packing machine pre-tape control device, which is arranged below the tape warehouse. The control device can timely sense the swing state of the balance stop lever, output a signal, and make the driving motor of the pre-tape feeding device work correspondingly, so that the pre-tape feeding device works or stops working correspondingly, so as to control the packing tapes stored in the tape warehouse within a reasonable range. However, the detection mechanism arranged below the tape warehouse cannot calculate the length of the tape, so it is not clear how long the tape is in the tape warehouse. Therefore, the tape warehouse is generally arranged to be relatively large, and a large amount of tapes stored in the tape warehouse may cause the tape to be not smooth. In addition, the detection mechanism needs additional space.

[0004] The prior art has the technical defects as described above, which is a great technical problem to be solved by the technical personnel in the field. INVENTION CONTENTS
