Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a ton bag packaging machine. Background Art

[0002] Ton bag packaging machine is a large weighing packaging equipment used for ton bag packaging materials. The lower part of the hanger of the ton bag machine is generally equipped with a clamping unit, also known as a bag clamping mechanism. At present, some ton bag machines on the market use air bags as bag clamping structures. The bag clamping structure generally requires a fixed plate with a maximum diameter larger than the inner diameter of the air bag to fix the air bag. This requires stretching the air bag to complete the installation of the air bag or destroying the air bag to complete the removal of the air bag, which is quite troublesome. For this reason, we propose a ton bag packaging machine. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Refer to the attached Figure 1-3The ton bag packaging machine includes a buffer hopper 1, a hanger 2, and a conveyor 3 arranged in sequence from top to bottom. The hanger 2 is equipped with at least one pair of clamping units 5 that slide radially along the discharge pipe and clamp the discharge pipe. The clamping unit 5 includes a driving cylinder 51, a driving connecting rod 52, and a connecting plate 55. The driving cylinder 51 is horizontally placed on the hanger 2, and the tail end of the driving cylinder 51 is hinged on the hanger 2. The output end of the driving cylinder 51 is hinged to the middle of the driving connecting rod 52 to form a swing structure, and the driving One end of the connecting rod 52 is hinged on the hanger 2, and the other end is hinged on the connecting plate 55. The output end of the driving cylinder 51 is connected to the driving connecting rod 52 to deflect it to drive the connecting plate 55 to approach the discharge pipe to form a clamp. When the driving cylinder 51 contracts, the driving cylinder 51 pulls the driving connecting rod 52 to swing clockwise, driving the connecting plate 55 to approach the discharge pipe. A clamping plate 57 is also installed on the connecting plate 55. The two clamping plates 57 cooperate to clamp the ton bag on the discharge pipe to form a clamp.

[0023] Furthermore, a stabilizing link 53 is hinged on the connecting plate 55 , and the stabilizing link 53 is hinged on the hanger 2 . The stabilizing link 53 and the driving link 52 move synchronously, thereby increasing the stability of the connecting plate 55 during movement.

[0024] Furthermore, a waist-shaped hole 21 is opened on the hanger 2, and a limiting rod 54 is connected to the driving connecting rod 52, and the limiting rod 54 extends into the waist-shaped hole 21 to form a limit.

[0025] Furthermore, a limiting rod 54 extending to the waist-shaped hole 21 is connected to the stabilizing link 53 .
