Packaging mechanism for tea packaging machine

Abstract

The invention discloses a packaging mechanism for a tea packaging machine. The packaging mechanism for the tea packaging machine comprises a fixed mold base, a movable mold base subjected to mold closing opposite to the fixed mold base, an upper hot sealing mechanism performing hot pressing sealing on tea packaging bags, an upper shaping mechanism providing lower pressure for the tea packaging bags, and a lower shaping mechanism providing upper pressure for the tea packaging bags; the fixed mold base and the movable mold base are each concavely provided with a vacuum cavity with a vacuum gas hole; the upper hot sealing mechanism comprises a fixed heating strip and a movable clamping strip; the upper shaping mechanism comprises a first shaping block and a second shaping block which can movedownwards synchronously; the lower shaping mechanism is provided with a left side plate, a right side plate and a shaping cavity; the lower shaping mechanism is located below the upper shaping mechanism and is between the fixed mold base and the movable mold base; and the fixed mold base is fixedly provided with a push-out mechanism for pushing the tea packaging bags out. Compared with the priorart, the packaging mechanism for the tea packaging machine can be used for packaging green tea and black tea, diverse in packaging function and achieves dual purposes, and the producing cost and the spaced occupied by the machine are greatly saved for tea merchants.

Description

technical field [0001] The invention relates to the field of tea packaging bags, in particular to a packaging mechanism for a tea packaging machine. Background technique [0002] As we all know, tea is generally packaged in small bags, and most of the traditional packaging methods are packaged by workers. After packing into the packaging bag, the tea packaging machine vacuumizes it, and heat seals the opening of the packaging bag after vacuuming. However, this kind of tea packaging machine can only be applied to the packaging of green tea, and cannot be adapted to the packaging of black tea. machine, and the tea packaging machine used for black tea packaging cannot be adapted to green tea packaging because it has no vacuum structure; thus, for tea merchants, it is necessary to purchase two types of tea packaging machines in the factory, one is for A packaging machine for green tea and a packaging machine for black tea, which will undoubtedly increase the cost of the tea me...

[0002] As we all know, tea is generally packaged in small bags, and most of the traditional packaging methods are packaged by workers. After packing into the packaging bag, the tea packaging machine vacuumizes it, and heat seals the mouth of the packaging bag after vacuuming

However, this kind of tea packaging machine can only be applied to the packaging of green tea, and cannot be adapted to the packaging of black tea. machine, and the tea packaging machine used for black tea packaging cannot be adapted to green tea packaging because it has no vacuum structure; thus, for tea merchants, it is necessary to purchase two types of tea packaging machines in the factory, one is for A packaging machine for green tea and a packaging machine for black tea, which will undoubtedly increase the cost of the tea merchant and occupy the area of ​​the manufacturer; moreover, the existing black tea packaging, when it is reshaped and packaged, its work flow is roughly like this , put down the bag first, then seal the bag, after sealing, pull down the bag directly through the pull-down mechanism, and press it on the tea leaves in the bag, and then the top-up mechanism pushes up, because only the two sides of the tea bag in the width direction are adjusted during shaping. The upper and lower sides are extruded and shaped, but the two sides of the tea packaging bag in the thickness direction cannot be shaped, so that the two sides of the shaped tea packaging bag in the thickness direction sometimes have concave folds, which cannot be straight and flat, and the packaging effect is not good. In addition, the topping machine needs to do several intermittent toppings on the tea packaging bags during the plastic surgery, which is troublesome.
