Bag catching device

Abstract

The invention discloses a bag catching device which comprises a support rod and two groups of bag clamping pliers components which are arranged on the support rod. Each of the two groups of bag clamping pliers components comprises a clamping mechanism and a clamping drive mechanism. The clamping mechanisms are composed of mutually hinged fixed pliers and movable pliers, and the clamping drive mechanisms drive the movable pliers to rotate. The fixed pliers are connected with the ends of fixed shafts, and the other ends of the fixed shafts are connected with the support rod. The clamping drive mechanisms comprise transmission sleeves and rotary drive mechanisms. The movable pliers are connected with the ends of the transmission sleeves, the other ends of the transmission sleeves are connected with the rotary drive mechanisms, and the transmission sleeves are sleeved on the peripheries of the fixed shafts and rotate relative to the fixed shafts under the action of the rotary drive mechanisms. By means of the bag catching device, packaging bags can be clamped rapidly and accurately and subjected to heat sealing by corresponding heat sealing apparatuses; besides, each bag catching device clamps one packaging bag, clamping between the adjacent packaging bags are not affected, and the adjacent packaging bags can be arranged longitudinally, so that the problems of instable clamping and limited clamping number are solved.

Description

technical field [0001] The invention belongs to the field of food processing equipment, in particular to a bag receiving device. Background technique [0002] At present, in the fully automatic filling vacuum packaging production line of materials, how to quickly and accurately catch the packaging bags conveyed by the previous process and send them to the vacuum packaging machine for packaging is the key to realize the production of materials from filling to vacuum packaging assembly line . [0003] In the existing automatic vacuum packaging machine, the conveying and clamping action of the packaging bag is realized by the reverse rotation of two long conveyor belts that are close to each other. Several packaging bags to be sealed are arranged along the conveying direction of the conveyor belt. The above structure mainly exists The following problems: 1. Because the conveyor belt is too long, after a long time of use, it is impossible to ensure the stable clamping of the tw...

[0003] In the existing automatic vacuum packaging machine, the conveying and clamping action of the packaging bag is realized by the reverse rotation of two long conveyor belts that are close to each other. Several packaging bags to be sealed are arranged along the conveying direction of the conveyor belt. The above structure mainly exists The following problems: 1. Because the conveyor belt is too long, after a long time of use, it is impossible to ensure the stable clamping of the two conveyor belts to the packaging bag; The number of clamped bags is limited, and the packaging efficiency is not high
