Sliding roll-cutting type semiautomatic film cutting machine for fruit film bags

Abstract

The invention discloses a sliding roll-cutting type semiautomatic film cutting machine for fruit film bags. The film cutting machine comprises a rack, and a film cutting device and a fixing and pressing device, which are arranged on the rack. The film cutting device comprises a film cutting working tabletop, guide-track grooves, cylinders and roll-cutting discs, wherein the guide-track grooves are formed in the film cutting working tabletop; and the roll-cutting discs are driven by the cylinders to rotate, and reciprocally move in the guide-track grooves. The fixing and pressing device comprises pressing handles, wherein the pressing handles are arranged above a plastic film bag strip to be cut, and are used for fixing and pressing the plastic film bag strip. The fixing and pressing device for pressing the plastic film bag strip and a plurality of roll-cutting discs are arranged, a plurality of parts of the plastic film bag strip formed by stacking plastic fruit film bags with the film thicknesses of 0.003 to 0.01mm are subjected to semiautomatic film cutting at the same time, and a maximum thickness of the plastic film bag strip to be cut can reach 15cm, so that the aim of improving the film cutting efficiency and the quality of a product is fulfilled.

Description

technical field [0001] The invention relates to a film cutting device, in particular to a semi-automatic film cutting machine for sliding roll cutting type fruit film bags. Background technique [0002] In the process of fruit growth, in order to prevent the harm of diseases and insect pests and improve the quality and yield of fruit, it is necessary to protect the fruit. The general protection method is to put a protective bag on the fruit when the fruit is young. There are two commonly used protective bags, one One is a double-layer protective bag, the outer layer is a paper bag, and the inner layer is a plastic film bag. After the fruit grows to a certain stage, the double-layer protective bag will fall off separately; Putting on a plastic film bag, especially a plastic film bag with a horizontal iron wire that can be sealed is the most practical; but at present, a production process of the plastic film bag is to pile up the produced plastic film bags to a certain thi...

AI Technical Summary

Problems solved by technology

[0006] 1. Since the film thickness of a single plastic film bag is between 0.003-0.01mm, not only the thickness is very thin, but also very soft, and it is easy to be scattered during the film cutting process. When cutting the film, the long strips of plastic film bags are often piled up to a certain Thickness and then start to cut the film, and the film cutting device uses two sets of drive rollers to achieve the purpose of pressing the strips of plastic film bags, but the structure of the device is complex and not suitable for cutting thicker strips of plastic film bags, cutting film less efficient

2. The structure of the film cutting device is complex, the operator is not easy to get started, and it is not easy to maintain when a fault occurs

3. Since the cutting knife of the film cutting device is fixed on the rotary knife roller rotating around the axis, the cutting speed of the cutting knife is equivalent to the speed of the movement of the strips of plastic film bags, and the strips of plastic film bags are always in motion. When cutting the film, the knife speed is relatively slow. When cutting the film, it is easy to cut the long strips of plastic film bags or the quality of the cut fruit bagging is poor, causing the strips of plastic film bags to be scattered, wasting materials, and even causing machine damage

4. There is only one cutter in the device, and it cannot cut multiple places on the plastic film bag strip at the same time. The speed of cutting the film is slow, which affects the production efficiency

5. It is especially not suitable for cutting plastic film bags with horizontal iron wires. Since the plastic film bags with horizontal iron wires are stacked into strips of plastic film bags with a certain thickness, the thickness of the horizontal iron wires is thicker than that of the plastic film bags. , the strips of plastic film bags stacked to a certain thickness are uneven, not easy to compress, and the quality of the produced products is poor
