Packing machine pushing mechanism

Abstract

The invention discloses a material pushing mechanism of a packaging machine, which has a frame and a transmission belt, the transmission belt cooperates with a belt winding assembly, the transmission belt is connected with a moving frame, a pushing assembly and a pressing assembly are arranged on the moving frame, and a guide seat is connected to the moving frame , the guide seat has a first roller and a second roller correspondingly arranged up and down, and a third roller and a fourth roller correspondingly arranged front and back, the guide seat is movably arranged on the frame plate, and the frame plate is provided with an outer ring around its outer edge. For the convex part, the first and second rollers respectively press against the upper and lower sides of the outer convex part, and the third and fourth rollers respectively press against the front and rear sides of the frame plate. The invention has the advantages of simple structure, reasonable design and good comprehensive performance, and can smoothly and smoothly carry out the operation of pushing and pressing materials of the packaging machine.

Description

technical field [0001] The invention relates to packaging equipment, in particular to a material pushing mechanism of a packaging machine. Background technique [0002] The pushing and pressing mechanism is one of the important components of the packaging machine. It mainly includes a pushing component and a pressing component. When working, the pressing component first presses the material, and then the pushing component pushes the material into the packaging box Realize the loading operation, in which the packaging box is continuously moved under the drive of the conveyor belt, and the pressing assembly and the pushing assembly are set on the moving frame, and the moving frame will drive the pressing assembly and pushing assembly to keep the packing box Move synchronously, and drive the pressing and pushing components to reciprocate in the direction of the packaging box through the guide assembly, and then push the material into the packaging box. [0003] The pushing mat...

AI Technical Summary

Problems solved by technology

[0003] The pushing material mechanism of the above structure has certain defects in the actual use process: first, the stability and smoothness of the movement cannot be guaranteed during the moving process of the mobile frame, and vibration and offset may occur, which in turn cannot guarantee The pushing material component moves to the pushing material position accurately to complete the pushing of the material; second, the moving frame is generally driven by a chain to move, but the chain will inevitably loosen during long-term use , which leads to inaccurate sprocket transmission and a lot of noise. The traditional solution is to add a tensioner to the chain and adjust the tensioner regularly. However, the installation space of the chain of some packaging machines is small, and it is impossible to increase the tensioner. Moreover, the above-mentioned solution needs to regularly check the tightness and adjust the links of the chain, which greatly increases the workload of maintenance; of course, in addition to the above-mentioned problems, there is also the fact that the structure of the pushing material assembly and the guide assembly is relatively complicated, and collisions are prone to occur during use. ; and the replacement of the pushing and pressing parts on the pushing and pressing material assembly is more troublesome; when the thickness of the material changes, the height of the pressing material assembly is difficult to adjust adaptively, which is already difficult to meet the needs of users at this stage
