Bag clamping mechanism of automatic plastic particle packaging machine

Abstract

The invention relates to a bag clamping mechanism of an automatic plastic particle packaging machine. The bag clamping mechanism comprises a fixed plate, multiple first air cylinders mounted on the fixed plate, a movable plate connected to the lower end of each first air cylinder, multiple mounting brackets connected to the lower end of the movable plate, a discharging speed control mechanism, multiple transverse bag clamping mechanisms and a bag edge clamping mechanism connected to the discharging speed control mechanism, wherein the discharging speed control mechanism and the transverse bag clamping mechanisms are connected to the mounting brackets; and the transverse bag clamping mechanisms are used for clamping bag bodies located on the two sides of the discharging speed control mechanism, and the bag edge clamping mechanism is used for clamping the bag bodies attached to the discharging speed control mechanism. According to the bag clamping mechanism of the automatic plastic particle packaging machine, a bag opening can be fixed at multiple points, the clamping effect is better, and the bag clamping mechanism is suitable for bag bodies with different lengths and different bag opening widths, the bag bodies can be shaken in the vertical direction and the horizontal direction in the bagging process, and materials in the bag bodies can be stacked more densely.

Description

technical field [0001] The invention belongs to the technical field of bag clamping of packaging machines, and in particular relates to a bag clamping mechanism of an automatic packaging machine for plastic particles. Background technique [0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and can be subdivided into thousands of types. Common plastic particles include general-purpose plastics, engineering plastics, and special plastics. General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbon silicone, etc. Special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. [0003] There are many types of packaging machinery, which can be divided into pre-packaging machinery, packaging machinery and post-packaging machinery. In terms of functions and p...

Problems solved by technology

[0012] Usually, in the production process of plastic granules, automatic packaging machines are mostly used for bagging processing. However, the clamping range of the bag clamping mechanism in the common plastic granule packaging machines is relatively narrow at present, which cannot be applied to different Bags of different lengths and widths, and the bag cannot be shaken during the bagging process, so the material is prone to insufficient accumulation in the bag
