Example Embodiment

Reference figure 1 And combine figure 2 with image 3 . An empty outer bag suction mechanism of a tea vacuum packaging machine with bag mouth shaping function. The empty outer bag suction mechanism 1 includes a sliding seat 11 movably arranged on a working platform 1a and a driving cylinder 12 that drives the sliding seat 1. The sliding seat 11 A bag taking cylinder 12 is fixedly installed on the upper part, and a bag taking suction cup seat 13 with a bag taking suction cup 14 is fixedly mounted on the top of the piston of the bag taking cylinder 12 extending upward. An outer bag placer 2 and an empty outer bag opening mechanism 3 are arranged at intervals above the bag suction cup seat 13. The driving cylinder 12 drives the sliding seat 11 to reciprocate between the outer bag placing device 2 and the empty outer bag opening mechanism 3.

Reference figure 2 with image 3 And combine figure 1 The middle of the top surface of the bag taking sucker seat 13 is provided with a gro...

Abstract

The invention provides an external bag opening shaping method of an automatic vacuum packaging machine for tea and an apparatus thereof. The apparatus comprises an empty external bag absorbing and sending mechanism, which is capable of reciprocating between an empty external bag holding device and an empty external bag expanding mechanism and is provided with a bag-fetching sucker holder with a bag-fetching sucker; a through groove is arranged at the middle of the top surface of the bag-fetching sucker holder; the bag-fetching sucker is installed on the bottom surface of the groove; the opposite sides of two side walls of the groove are correspondingly provided with a shaping and blowing opening; the bag-fetching sucker holder is provided with an air inlet for connecting an external air source and an air passage for communicating with the shaping and blowing opening and the air inlet. After the empty external bag is charged, in the process that the bag expanding sucker and the bag-fetching sucker are close to each other again, the shaping and blowing opening aims at the middle part of the foldable side of the empty external bag and blows continuously; the continuous blowing forcibly makes the middle part of the foldable side of the empty external bag fold inwards and ensures that the external bag opening recovers the folded shape of the side after the bag expanding sucker and the bag-fetching sucker are compacted with each other. The invention has the advantages of simple structure, reliable work, automatic shaping of the external bag opening and improvement of the excellent rate of the finished product to the maximum.

Description

[0001] Technical field [0002] The invention belongs to automatic tea packaging equipment, in particular to a method and device for shaping the outer bag opening of an automatic vacuum packaging machine for tea. [0003] Background technique [0002] In order to prolong the shelf life, freshness, moisture and odor of tea, facilitate storage and better adapt to the needs and use of consumers at different levels, the tea is usually vacuum-packaged and sold in small packages of 5-10 grams. In order to realize the automatic filling of the outer bag, the current common vacuum packaging machines include an outer bag suction mechanism and an outer bag opening mechanism matched with the outer bag suction mechanism. The outer bag suction mechanism is placed from the outer bag. An empty outer bag is sucked from the dispenser and transferred to the corresponding position of the outer bag opening mechanism. The opening of the empty outer bag is expanded by the outer bag opening mechanism, a...
