Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an air bag clamp for packaging. Background Art

[0002] Ton bag scales are typically used for large-volume, rapid, and specialized quantitative weighing and packaging of solid granular or powdered materials. They are also specialized equipment for large-volume flexible bag packaging. They are multifunctional packaging machines that integrate electronic weighing, automatic bagging, and dust removal. They offer a high degree of automation, high packaging accuracy, and adjustable packaging speed. These machines are suitable for packaging large bags in industries such as cement, building materials, chemicals, pesticides, fertilizers, rubber, plastics, metallurgy, fertilizers, grain, energy and minerals, pharmaceuticals, food, and lithium batteries. However, the pre-bag securing process can lead to loose bagging, which can cause material leakage, increasing production costs and impacting the production environment. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide an air bag clamp for packaging, which is more stable and reliable in clamping bags and is less likely to leak.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a packaging air bag clamp, characterized in that it has an inner cylinder, an outer cylinder and a positioning air bag, the outer cylinder is sleeved outside the inner cylinder, the positioning air bag is arranged between the inner cylinder and the outer cylinder, a connecting flange is provided on the upper outer periphery of the inner cylinder, and the outer cylinder can be adjustably connected to the connecting flange by an adjusting bolt.

[0005] In the above technical solution, the outer cylinder is annular and is concentrically arranged with the inner cylinder, and the radius of the outer cylinder is greater than the radius of the inner cylinder.

[0006] In the above technical solution, the positioning airbag is covered on the outer periphery of the inner cylinder.

[0007] In the above technical solution, an air inlet and an air outlet are provided on the upper portion of the positioning airbag.

[0008] In the above technical solution, pressure detection switches are provided at the air inlet and the air outlet.

[0009] In the above technical solution, a pneumatic vibrator is provided on the inner cylinder.

[0010] In the above technical solution, the positioning airbag is made of silicone.

[0011] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the outer and inner cylinders of the present invention adopt an annular design and are arranged on the outside of the inner cylinder to play a limiting role. When in use, the airbag is inflated to fix the bag opening. At the same time, the outer cylinder adopts a detachable and height-adjustable structure, which can better adapt to different packaging environments. During the packaging process of powder materials, the bag opening can be clamped stably and reliably to ensure no dust leakage, meeting the customer's on-site environmental requirements.
