Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a shaping mechanism and packaging machine for an M-shaped packaging bag. Background Technology

[0002] Existing packaging bags are generally divided into three-side seal bags, four-side seal bags, irregularly shaped bags, M-shaped packaging bags, etc. Among them, the longitudinal two sides of the M-shaped packaging bag are concave and have an M-shaped structure.

[0003] Currently, during the filling process of M-shaped packaging bags, the bag opening is stretched open to allow materials to fall in, which damages the M-shaped edges of the bag and causes inconvenience to subsequent processes. Some manufacturers use manual shaping to solve this problem, but it is labor-intensive and inefficient. In view of this problem, some manufacturers have designed M-shaped packaging bag shaping structures, but the existing M-shaped packaging bag shaping mechanisms on the market have problems such as complex structures and poor shaping effects. Therefore, there is an urgent need to solve this problem. Utility Model Content

[0028] In this embodiment, a shaping mechanism for an M-shaped packaging bag includes:

[0029] Frame 1 serves a supporting function;

[0030] An inner clamping component, installed on the frame 1, is used to attach an M-shaped packaging bag;

[0031] An outer clamping assembly is mounted on the frame 1, and the outer clamping assembly can cooperate with the inner clamping assembly to compress the M-shaped packaging bag;

[0032] The insert bag assembly, mounted on the frame 1, is used to shape the M-shaped packaging bag.

[0033] Specifically, in this embodiment, the inner clamping assembly includes a first set of bag clamping plates 8 and a second set of bag clamping plates arranged symmetrically, and a first driving device for driving the first set of bag clamping plates 8 and the second set of bag clamping plates to separate / close in the horizontal X-axis direction.

[0034] Specifically, in this embodiment, the outer clamping assembly includes a first fixing plate and a second fixing plate arranged symmetrically, and a second driving device for driving the first fixing plate and the second fixing plate to separate / close in the horizontal X-axis direction. The first fixing plate is located outside the first bag clamping plate 8, and a first pressure block 10 is installed on the inner end of the first fixing plate. The second fixing plate is located outside the second bag clamping plate, and a second pressure block is installed on the inner end of the second fixing plate.

[0035] Specifically, in this embodiment, the insert assembly includes a first insert plate 4 and a second insert plate arranged symmetrically, and a third driving device for driving the first insert plate 4 and the second insert plate to separate / close in the horizontal Y-axis direction.

[0036] Specifically, in this embodiment, a side-pull assembly for moving the insert bag assembly is installed on the frame 1. The side-pull assembly includes a side-pull cylinder 2 installed on the frame 1. The output end of the side-pull cylinder 2 is connected to a side-pull frame 5, and the insert bag assembly is installed on the side-pull frame 5.

[0037] Specifically, in this embodiment, the third driving device includes a first insert cylinder 3 and a second insert cylinder.
