Can seaming machine for tea cans

Abstract

The invention relates to the field of tea production equipment, and particularly relates to a can seaming machine for tea cans. The problem mainly solved is to develop a packaging machine capable of lowering the production cost on the premise of ensuring reliable sealing for packaging cans. The can seaming machine comprises a rack, a clamping-conveying device, a can seaming device, a tea sub-packaging machine and a control device, wherein the can seaming device comprises a winding-unwinding device; a sealing upper die and a cutting upper die are arranged on the rack; a heat sealing device is arranged on the sealing upper die; a guide column is arranged on the rack; a movable plate is arranged on the guide column; a first drive device driving the movable plate to move is arranged on the rack; a sealing lower die and a cutting lower die are arranged on the movable plate separately; a vacuumizing device and a nitrogen-making device are arranged at an air exhaust end and an air intake endseparately; a bearing plate is arranged in the sealing lower die; and a second drive device driving the bearing plate to move up and down is arranged on the rack. A sealing film cloth is prevented from being deflected, so that the can seaming efficiency is increased.

Description

technical field [0001] The invention relates to the field of tea production equipment, in particular to a tea can sealing machine. Background technique [0002] At present, more and more items including tea, food, and precious Chinese medicinal materials are packaged in small independent packages, which is convenient for consumers to take in quantitative quantities, and at the same time can improve the packaging grade of products. Therefore, both distributors and consumers gradually accept small packaging. individual packaging. In the field of tea, the known tea independent packaging cans are all: the tea leaves are pre-loaded into the tank body, and then the lower surface of the cover is sprayed with glue by a glue spraying device and then compounded and pasted on the opening of the tank body. The thickness of the tank body, or the opening of the tank body extends inward and laterally to set a convex edge, or the constriction part is partially recessed in the upper lateral...

Problems solved by technology

In the field of tea, the known tea independent packaging cans are all: the tea leaves are pre-loaded into the tank body, and then the lower surface of the cover is sprayed with glue by a glue spraying device and then compounded and pasted on the opening of the tank body. The thickness of the tank body, or the opening of the tank body extends inward and laterally to set a convex edge, or the constriction part is partially recessed in the upper lateral middle part of the tank body, based on the existence of the constriction part, a supporting platform is formed at the top of the tank body, In order to ensure that the cover and the tank are firmly bonded, otherwise the reliable sealing connection between the cover and the tank cannot be ensured. The disadvantage of these packaging cans is the waste of materials, especially at present, more and more aluminum alloy or iron bottles are used When it comes to body, the structure of the packaging bottle itself is an important part of the cost of the packaging can, so it is necessary to develop a new type of packaging machine to improve its packaging method to reduce the production cost of the can
