Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a rotary bag clamping mechanism for packaging. Background Art

[0002] Ton bag packaging scales are typically used for large-volume, rapid, and specialized quantitative weighing and packaging of solid granular or powdered materials. They are also currently specialized equipment for large-volume soft bag packaging. They are multifunctional packaging machines that integrate electronic weighing, automatic bag removal, and dust removal. They offer not only a high degree of automation but also high packaging precision and adjustable packaging speed. Ton bag packaging 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, during the pre-packing process, the bags need to be clamped to a fixed frame. The large frame requires operators to first clamp the front hook of the machine and then work their way around to the rear to clamp the rear hook, making this operation very inconvenient. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a rotary bag clamping mechanism for packaging, which is simple to operate and more convenient to use.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a rotary bag clamping mechanism for packaging, comprising a fixed frame, a plurality of hook frames being provided on the fixed frame, a hook being hingedly connected to the lower portion of the hook frame, and a hook frame rotating assembly being provided at the inner hook frame, the hook frame rotating assembly comprising a hook frame rotating cylinder and a hook frame rotating connecting rod thereof, one side of the hook frame being hingedly connected to the fixed frame and being capable of rotating relative to the hook frame driven by the hook frame rotating cylinder, a hook frame being provided with a hook rotating cylinder, and the hook being capable of rotating under the push of the hook rotating cylinder.

[0005] In the above technical solution, a bag clamp is provided in the middle of the fixing frame.

[0006] In the above technical solution, the fixing frame is square, hook frames are provided on the four corners of the fixing frame, and hook frame rotating components are provided on the two inner corners.

[0007] In the above technical solution, the hook rack rotating cylinder is arranged along the side of the fixed frame, the hook rack rotating connecting rod is a rocker rod with a 90° bend in the middle, and the hinge shaft of the hook rack is installed on the hook rack rotating connecting rod.

[0008] In the above technical solution, the hook frame includes a horizontal frame and a vertical frame, the horizontal frame is hinged to the fixed frame, and the vertical frame is connected to the horizontal frame through adjusting bolts.

[0009] In the above technical solution, a plurality of adjustment holes are provided on the horizontal frame and the vertical frame, and the adjustment bolts are installed in the adjustment holes.

[0010] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the present invention provides a hook rack rotating assembly and a hook rotating cylinder, and a reasonable rotating structure design can rotate the hook rack and the hook during clamping. The hook rack rotating assembly can ensure that the two hook assemblies located opposite the operator can be rotated close to the operator, which is convenient for hanging bags. The hook can also be automatically retracted and unhooked through the hook rotating cylinder, which is convenient for bag hanging operations. The entire bag hanging operation is more convenient and can be completed by one person. BRIEF DESCRIPTION OF THE DRAWINGS
