Vacuum sealing and shaping device of tea packing machine

Abstract

The invention provides a vacuum sealing and shaping device of a tea packing machine. The vacuum sealing and shaping device comprises a machine frame, a sealing mechanism, an air extraction mechanism and a shaping mechanism, wherein the air extraction mechanism and the shaping mechanism are installed on the machine frame from top to bottom in sequence; and a material jacking mechanism is installedin the position, corresponding to the shaping mechanism, of the machine frame. The air extraction mechanism comprises a first horizontal air cylinder installed on the machine frame, a left shell connected with a piston rod of the first horizontal air cylinder, a right shell opposite to the left shell, a connection rod, a longitudinal installation plate and a second horizontal air cylinder installed on the machine frame from left to right in sequence, a piston rod of the second horizontal air cylinder sequentially penetrates through the longitudinal installation plate, the connection rod and the right shell, and the left shell and the right shell are provided with a first inwards concave cavity and a second inwards concave cavity correspondingly. The sealing mechanism comprises a third horizontal air cylinder installed on the longitudinal installation plate, a first sealing heat chuck and a second sealing heat chuck opposite to the first sealing heat chuck, the first sealing heat chuckis installed on the left shell and located in the first cavity, and a piston rod of the third horizontal air cylinder penetrates through the right shell and is connected with the second sealing heat chuck movably arranged in the second cavity.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to a vacuum sealing and shaping device of a tea packaging machine. Background technique [0002] In order to prolong the shelf life and fresh-keeping period of tea leaves, to facilitate storage and to better adapt to the needs and use of consumers at different levels, tea leaves are usually vacuum-packed. After the existing tea packaging machine puts the tea into the packaging bag, it usually puts the whole packaging bag in a closed chamber for vacuuming and then heat-seals it. The volume of the closed chamber is large, which leads to slow vacuuming speed and high power consumption. High-quality vacuum pumps increase packaging costs, low work efficiency, complex equipment structure, large space occupation, and high maintenance costs. [0003] In view of this, the inventor specially designed a vacuum sealing and shaping device of a tea packaging machine, and this case arose f...
