Description

Technical Field

[0001] This utility model relates to the field of automatic bag opening binding technology for ton bags, specifically to an auxiliary device for automatic bag opening binding after ton bag filling. Background Technology

[0002] Ton bag mouth tightening refers to the operation of tightening, sealing or binding the mouth of the ton bag in a specific way to ensure that the material inside the bag will not leak during transportation and storage, and to avoid contamination or loss.

[0003] Currently, the closing of ton bag openings is mostly done manually by workers. This manual operation is not only costly and inefficient, but also poses a risk to workers' health when hazardous chemicals or powders are being filled and spilled during the closing process. This makes the closing and binding of ton bag openings unsafe. Utility Model Content

The actuating end of the retracting arm actuating assembly is connected to the rear retracting arm. A right retracting arm actuating cylinder is installed on the frame on the side opposite to the left retracting arm actuating cylinder. The telescopic part of the right retracting arm actuating cylinder is connected to the right retracting arm. A right retracting arm rotating pin is installed at the connection point between the right retracting arm and the frame. A front retracting arm actuating assembly is installed on the right retracting arm near the right retracting arm rotating pin.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3 As shown in this embodiment, an automatic bag-tying auxiliary device for ton bag filling includes a frame 1. A left-side retracting arm actuation cylinder 7 is installed on the side of the frame 1 facing the ton bag filling port. The telescopic part of the left-side retracting arm actuation cylinder 7 is connected to a left-side retracting arm 11. The left-side retracting arm actuation cylinder 7 is mainly used to provide power for the rotation of the left-side retracting arm 11. A left-side retracting arm rotating pin 8 is installed at the connection between the left-side retracting arm 11 and the frame 1. A rear retracting arm actuation assembly 10 is installed on the side of the left-side retracting arm 11 away from the left-side retracting arm rotating pin 8. The actuating end of the rear retracting arm actuation assembly 10 is connected to a rear retracting arm 9. The rear retracting arm actuation assembly 10 mainly uses its own motor to realize the retraction of the rear retracting arm 9 along the left side. The sliding of arm 11 achieves the closure of the ton bag opening. On the frame 1, opposite to the left-side closing arm actuating cylinder 7, a right-side closing arm actuating cylinder 2 is installed. The telescopic part of the right-side closing arm actuating cylinder 2 is connected to the right-side closing arm 4. The right-side closing arm actuating cylinder 2 is mainly used to provide power for the rotation of the right-side closing arm 4. A right-side closing arm rotating pin 3 is installed at the connection between the right-side closing arm 4 and the frame 1. A front closing arm actuating assembly 5 is installed on the right-side closing arm 4 near the right-side closing arm rotating pin 3.
