Packaging device for agricultural product machining and with automatic exhaust closing and hot-pressing sealing functions

Abstract

The invention relates to the technical field of agricultural products, and discloses a packaging device for agricultural product machining and with automatic exhaust closing and hot-press sealing functions. The packaging device comprises a shell, wherein a first rotating disc is movably connected to the interior of the shell; gears rotate to enable two pressing plates to change between a state ofmoving upwards and being close to each other and a state of moving downwards and being away from each other, a packaging bag containing a finished product is automatically exhausted, the space occupied by the packaged finished product is reduced, the space utilization rate is increased, the situation that the packaging bag is extruded and exploded due to excessive air in the packaging bag is avoided, the opening degree of a bag opening is reduced, the situation that the bag opening shrinks and cannot be effectively heat-sealed due to too early heat shrinkage of the bag opening is avoided, a moving rod moves up and down to enable two heat sealing rod vertical rods to change between a state of moving downwards and being close to each other and a state of moving upward and being away from each other, so that heat sealing blocks on the outer sides of the vertical rods automatically carry out double-sided extrusion heat sealing on the bag opening, the connection of the sealing part of the packaging bag is firm, and finished product falling is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural products, in particular to a packaging device for processing agricultural products that automatically vents and closes and heat-presses. Background technique [0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties in various regions. Agricultural products enter the consumption field from the production field and need to be processed. Agricultural product processing is a production activity that uses physical, chemical and biological methods to make the main and by-products of agriculture into various foods or other supplies. The processed agricultural products It needs to be packaged by packaging equipment to facilitate the transportation and sales of agricultural products. [0003] Usually when the finished product is packaged, the finished product is bagged and sealed at high temperature with the help of a sealing...

AI Technical Summary

Problems solved by technology

However, before the packaging bag containing the finished product is sealed, the finished product will continuously hit the packaging table due to the vibration of the conveying device, and the opening angle of the bag will increase. When the sealing device seals it, it may contact the packaging bag prematurely. The bag mouth will be heat-shrunk, the bag mouth will not be fully sealed, and the sealing effect will be poor. Generally, the packaging bag containing the finished product contains air, so that when the packaging bag is hit, it has a certain buffering and protective effect on the finished product in the packaging bag. However, when the air content is high, the possibility of the packaging bag being squeezed and bursting is increased, and the space occupied by the packaging bag with high air content is larger, which reduces the space utilization rate and increases the cost of packaging and transportation.

[0004] Aiming at the deficiencies of the prior art, the present invention provides a packaging device for processing agricultural products that automatically vents and closes the mouth and heat-presses the seal. The problem of large space and poor heat sealing effect, automatically exhausts the packaging bag containing the finished product, reduces the space occupied by the packaged product, increases the space utilization rate, and avoids crowding due to too much air in the packaging bag In the case of pressure bursting, and reduce the opening degree of the bag mouth, to avoid premature heat shrinkage of the bag mouth, resulting in shrinkage of the bag mouth, which cannot be effectively heat-sealed, it can automatically perform double-sided extrusion heat-sealing on the bag mouth, and the packaging bag The connection at the sealing part is more firm, which can effectively prevent the finished product from falling
