Description

The main function of this transition plate is to support the preformed bag and prepare for the smooth opening of the bag mouth by the subsequent second bag suction mechanism. This design improves the automation degree of preformed bag handling to a certain extent.

[0003] However, in actual use, the prior art relies on the pushing force of the tray driven by the roller chain ring and the moving inertia of the preformed bag to make it reach the transition plate. This method has the following disadvantages: first, due to the reliance on the pushing force and inertia movement of the tray upstream, the speed of the preformed bag reaching the transition plate is slow or some preformed bags with insufficient power cannot reach the predetermined position of the transition plate or fall off, which directly affects the efficiency of the entire packaging process. Secondly, the position of the preformed bag during movement is difficult to control accurately, which not only increases the difficulty of subsequent operations, but also may adversely affect the packaging quality and running speed.

These defects are difficult to meet the continuous pursuit and demand of modern production lines for efficient and accurate packaging, and improvement is urgently needed. UTILITY MODEL CONTENTS

3. The standby bag feeding device according to claim 1, wherein the top surface of the power roller is parallel to the upper surfaces of the two roller chains of the bag arranging mechanism and is in the same plane.

4. The standby bag feeding device according to any one of claims 1-3, wherein: the non-powered bag pressing wheel set is composed of two or more than two coaxially arranged roller intervals.

5. The bag-on-pallet apparatus of claim 4, wherein: The rollers are rubber rollers.

6. The bag-on-pallet apparatus of claim 1, wherein: The bag arranging mechanism is also provided with a forward and reverse toothed screw double slider module on the conveying path of the single prefabricated bag to the transition plate, two sliders of the forward and reverse toothed screw double slider module are respectively provided with a bag arranging plate, and the two bag arranging plates are parallel to each other to limit the single prefabricated bag between the two bag arranging plates.

7. The bag-on-pallet apparatus of claim 6, wherein: The bag arranging mechanism also comprises a tray formed by a plurality of support rods arranged at intervals on the conveying path of the single prefabricated bag to the transition plate, and soft bristles are arranged on the edge of the side of the bag arranging plate close to the tray.

8. The bag-on-pallet apparatus of claim 7, wherein: The soft bristles extend towards the tray, or are inclined towards the tray and the opposite slider.

9. The bag-on-pallet apparatus of claim 8, wherein, The standby bag mechanism comprises a square standby bag bin and a moving mechanism, the bin bottom of the standby bag bin is spaced and horizontally laid as a hollow bin bottom by a plurality of square rod bodies, the length direction of the plurality of square rod bodies is parallel to the length direction of the forward and reverse toothed screw; the moving mechanism comprises a moving frame and a third air cylinder, the moving frame is slidingly arranged on the bin bottom, and the moving frame is driven to slide along the length direction of the square rod body by the third air cylinder to push a stack of prefabricated bags on the bin bottom into the lower part of the bag suction mechanism.

10. The bag-on-pallet apparatus of claim 9, wherein, One end of the standby bag bin is arranged in the rack and fixed with the rack, the other end of the standby bag bin extends outside the rack, so that half of the standby bag bin is located below the bag suction mechanism and the other half is located outside the support. Also include a screw module, the screw module is installed on the spare bag storehouse, the screw module includes a screw, a first slider, a baffle, a linear guide rail, two second support seats; The two second support seats are fixed below the plurality of square rod bodies, both ends of the screw are rotatably provided on the two second support seats through bearings, the screw, the reversible screw and the square rod body are parallel to each other, the baffle is arranged on the first slider, the baffle is aligned with a bag arranging plate close to one end of the spare bag storehouse up and down and parallel to each other in the same plane; The first slider is screwed on the threaded section of the screw and can slide along the linear guide rail; When the reversible screw double slider module and the screw module rotate synchronously, the baffle driven by the screw module is aligned with the bag arranging plate driven by the reversible screw double slider module and moves synchronously; The baffle is used to limit the position of a stack of prefabricated bags moving to the position of the bag suction mechanism, so that the position of a stack of prefabricated bags moving into the bag suction mechanism corresponds to the position between the two bag arranging plates on the bag arranging mechanism.
