Waste edge removal device for soft bag and method for removing waste edge of soft bag thereof

Abstract

The invention provides a waste edge removal device for a soft bag, which is used for removing the waste edge of the soft bag. The waste edge removal device comprises a base frame, a seam shaping component and a waste edge removing component, wherein the base frame is arranged at a shaping station of the soft bag with the waste edge; the seam shaping component is arranged on the base frame and is used for clamping and fixing the soft bag with the waste edge at the shaping station and shaping the seam of the soft bag; and the waste edge removing component is positioned below of the side of the seam shaping component and moves down to remove the waste edge of the soft bag. The whole waste edge removal device adopts relative isolation of a driving part and an execution part, and part of the structure above the top of the base frame adopts an easy cleaning mode without a dead angle, so that the aseptic production requirement can be met in the production process, and terminal products do notneed sterilization and can be instructed to the market after only outer packing. The invention further provides a method for removing the waste edge of the soft bag of the waste edge removal device for the soft bag.

Description

【Technical field】 [0001] The invention relates to soft bag processing technology, in particular to a device for removing waste edges of soft bags and a method for removing waste edges of soft bags. 【Background technique】 [0002] In the production process of the existing non-PVC film soft bag, such as figure 1 As shown, in order to make the appearance of the non-PVC film soft bag beautiful, the rounded corner design is often used for the packaging soft bag 1a, which will produce redundant waste edges 2a, if not removed in time or not completely, it will be in the subsequent In the sterilization process, the danger of waste edges blocking the pipeline will sometimes block the interface 1b of the packaging soft bag 1a; at the same time, if the waste edges 2a are not completely removed, it will increase the pollution of the production environment and affect the work of the light inspection staff. Efficiency increases costs virtually. In the prior art, the conventional removal...

AI Technical Summary

Problems solved by technology

[0004] At present, the plastic structure of the conventional soft bag production line, such as figure 2 As shown, it mainly includes the scrap edge tearing assembly and the shaping assembly. The driving cylinder 3a on the scrap edge assembly pulls the mechanical arm 4a connected to it and drives the air claw 5a, and the air claw 5a moves obliquely upward to drive the gripper on it. 6a clamps the waste edge 2a of the soft bag 1a and tears off the waste edge; in this structure, the driving cylinder 3a is located above the top plate 7a, and the structural limitation of the driving cylinder 3a itself will have a hygienic dead angle, resulting in an inability to effectively guarantee the aseptic state during the production process; and , because the waste edge tearing component uses a driving cylinder to pull the mechanical arm to tear up the waste edge, it is easy to cause microscopic particles such as powder chips generated when tearing off the waste edge to scatter and flow around, and then enter the interface of the soft bag, resulting in a soft bag contamination during packaging

[0005] Moreover, due to the limitations of the conventional soft bag line structure, the interface, the waste edge tearing component and the cylinder of the shaping component, the driving components are not isolated from the production environment, and are directly exposed to the production environment. Many, it may also cause damage to the production environment during the movement, such as compressed air leakage, lubricating oil splash, and the form of tearing off the waste edge obliquely will damage the laminar flow direction, and the particles produced by tearing the edge will also flying around etc.

At the same time, some structures also have hygienic dead corners. It is difficult to clean the equipment in place due to the existence of these hygienic dead corners, which is not conducive to maintaining a sterile environment. It is difficult to achieve a sterile environment during the production process of existing products. Therefore, the produced The product requires terminal sterilization to ensure sterility in the product
