Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a bag opening mechanism for a packaging machine. Background Technology

[0002] Packaging machines are divided into single-station and multi-station types. For bag opening, the current packaging machines on the market are equipped with different bag opening mechanisms by changing the design dimensions. This not only increases the number of parts and inventory, but also hinders mass production. The moving parts of the mechanism use plastic shafts or linear bearings, which result in large clearances and structural wobbling, affecting the success rate of bag opening. The structural adjustment of packaging machines in the industry is limited to a fixed range, which is not flexible in adaptability. Therefore, we propose a bag opening mechanism for packaging machines to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bag-opening mechanism for a packaging machine includes a servo motor, a triangular swing block, a mechanism mounting plate, and a motor mounting base. A reducer is fixedly mounted on the right side of the motor mounting base. The output end of the servo motor passes through the motor mounting base and is connected to a swing arm. A first pull rod is connected to the left side surface of the swing arm. The top end of the first pull rod is movably connected to the triangular swing block. Second pull rods are symmetrically fixedly connected to the upper and lower ends of the triangular swing block. A stainless steel protective cover is fixedly connected to the front of the mechanism mounting plate, and a guide rail mounting base is installed inside the stainless steel protective cover. A first protective cover and a second protective cover are installed on the right side of the stainless steel protective cover. A fixed base is fixedly connected to the back of the mechanism mounting plate, and a triangular swing block is installed on the right side of the fixed base. The triangular swing block and the fixed base are movably connected. A rear adjustment fixing component and a front adjustment fixing component are inserted inside the stainless steel protective cover.

[0006] Preferably, the guide rail fixing seat has a first guide rail and a second guide rail symmetrically inserted inside, and the first guide rail and the second guide rail are respectively connected to two sets of second tie rods.

[0007] Preferably, the first guide rail is fixedly connected to the front adjustment fixing member, and the second guide rail is fixedly connected to the rear adjustment fixing assembly.

[0008] Preferably, the right side of the rear adjustment fixing component is provided with a sliding groove, and the first guide rail is inserted inside the sliding groove.
