Problems solved by technology

[0003] The defect of this device is that when the width of the side material changes, the powder delivered to the hopper will also change, and the bulk density of the powder extruded by the compacting screw to the feed port of the extruder will also change, resulting in a thin film thickness. Unstable, and when there is too much powder, the powder will also bridge the feed port of the extruder, resulting in poor feeding

Abstract

The invention discloses an online recycling device for leftovers of a cast film. The online recycling device comprises a new material hopper communicated with an extruder, wherein an old material conveying pipeline is horizontally arranged on one side of the new material hopper; a conveying screw rod for conveying a powder material is arranged in the old material conveying pipeline; an old material conveying hopper is communicated with the upper part of the old material conveying pipe; one side of the old material conveying hopper is communicated with the old material conveying pipeline. Due to the adoption of the online recycling device disclosed by the invention, the powder material is quantitatively conveyed, so that the extrusion amount is stable. Therefore, the thickness stability of the product can be ensured; meanwhile, the device is uniform to stir in a blanking process and the bridging and blocking probabilities of the powder material can be reduced.

Description

technical field [0001] The invention relates to an on-line recovery device for casting film side material. Background technique [0002] During the production process of the casting film equipment, the side material will be cut off and pulverized online, and then sent to the extruder hopper through the fan to mix with the new material before entering the extruder. The hopper has a double-layer structure, the outer layer is fresh material, and the inner layer is powder. The powder conveyed by the fan enters the inner hopper through the cyclone separator. Since the powder is relatively light, there is a compacting screw in the middle of the inner hopper. The powder is extruded to the feed port of the extruder and mixed with the new material. Such as figure 1 As shown: 1 is the extruder, 2 is the powder compacting screw, 3 is the crushed powder conveying pipe, 4 is the cyclone separator, 5 is the air outlet pipe of the cyclone separator, 6 is the inner layer of the hopper, ...
