Description

Conveying structure for packaging bags Technical Field The utility model belongs to the technical field of packaging bag packaging mechanisms, and particularly relates to a conveying structure for packaging bags. Background With the rapid development of the packaging industry, the application of automatic equipment in production lines is becoming increasingly widespread. In the prior art, automatic bagging machines typically employ integral continuous bags as packaging materials. The packaging bags are supplied in a roll form, and in the bagging process, after the device fills the bags with materials, the individual packaging bags are cut from the continuous roll by a cutting mechanism, so that the packaging operation is completed. However, such conventional one-piece packages suffer from the significant drawbacks of 1, structural fixity limitations, the design of the one-piece continuous package in a non-detachable unitary form, with the cutting location and length being closely matched to the cutting mechanism of the apparatus. When the packaging requirements of different specifications are met, the equipment needs to frequently adjust the shearing parameters, so that the production efficiency is reduced, the flexible production requirements of multiple varieties and small batches are difficult to meet, and 2, the limitation of the shearing mechanism is that the conventional shearing mechanism usually depends on a mechanical blade or a heat sealing device to complete the cutting operation, and the action process is complex and time-consuming. In a high-speed production scene, the abrasion rate of the shearing mechanism is higher, the cutting precision is easy to be reduced, and even the problems of edge breakage, poor sealing and the like of the packaging bag are caused. In addition, disposal of the sheared waste material also increases equipment maintenance costs and energy consumption. 3. The compatibility of the split packaging bag is lost, and along with the increase of the demands of the split packaging bag (such as modularized combined packaging, detachable structure packaging and the like) in the market, the bagging mode of the traditional integrated packaging bag is difficult to adapt. The split packaging bag is usually composed of a plurality of independent units, and the complete packaging is realized through specific clamping, positioning and assembling processes. The existing automatic bagging machine lacks a special conveying and fixing structure for split bags, so that the bagging operation of the split bags cannot be completed efficiently, and the application of the automatic bagging machine in the fields with high requirements on packaging flexibility, such as foods, medicines and the like, is limited. 4. The production efficiency and the adaptability are contradicted, the cutting process of the integrated packaging bag needs to occupy extra stations and time, and the bagging process of the split packaging bag generally needs more complicated positioning and assembling steps. In the prior art, the characteristics of the split bags are not fully considered in the equipment design, so that shutdown adjustment is needed when the packaging mode is switched, and the overall efficiency of the production line is seriously affected. Disclosure of utility model The utility model aims to solve the technical problem of providing a conveying structure for packaging bags aiming at the current state of the art. The technical scheme adopted for solving the technical problems is that the utility model provides a conveying structure for packaging bags, which comprises a positioning piece and a conveying piece, wherein the positioning piece is used for stacking the packaging bags; the rotary platform is arranged on one side of the positioning piece, a plurality of clamping pieces are arranged on the rotary platform at intervals along the circumferential direction of the rotation center line of the rotary platform, the clamping pieces are in an unfolding state and a locking state, the unfolding state is used for receiving or releasing the packaging bag, and the locking state is used for fixing the packaging bag on the rotary platform; A driving block movably arranged above the rotary platform for controlling two adjacent clamping pieces to switch between the unfolding state and the locking state; And a carrying member provided at one side of the positioning member for carrying the packages on the positioning member individually to the holding member in the unfolded state. In one of the above conveying structures for packaging bags, the driving block includes a releasing position close to the rotating platform and a fixing position far away from the rotating platform; When the driving block is in the release position, the clamping piece is in the unfolding state; and when the driving block is in the fixed position, the clamping piece is in the locking state. In the above-mentioned conveying structure for pack
