Description

The semi-automatic film cutting machine of slippage Rolling cutting type fruit film-covering bag

Technical field

The utility model relates to a kind of film cutting apparatus, relates in particular to the semi-automatic film cutting machine of a kind of slippage Rolling cutting type fruit film-covering bag.

Background technology

In the fruit growing process, in order to prevent the harm of disease worm, improve the quality and yield of fruit, need to protect fruit, general guard method is to put protective bag when the fruit young fruit, and protective bag commonly used is divided two kinds, a kind of is the double shielding bag, skin is paper bag, and internal layer is plastic film bag, the double shielding bag is come off respectively behind certain phase until fruit growing again; Another kind is the single-layer plastic film bag, directly puts plastic film bag when young fruit, and particularly a kind of plastic sleeve film bag that can seal with horizontal iron wire is the most practical; But at present one production process of plastic film bag is that the plastic film bag that will produce is stacked into certain thickness to form plastic film bag rectangular, length by plastic film bag is cut into single plastic film bag, cutting method commonly used has following several: one, use survey tool, after the rectangular length of measuring the good film bag that needs cutting of plastic film bag, use object to push down plastic film bag and re-use the cutter cutting after rectangular; Two, it is rectangular to use the object such as batten to tightly suppress plastic film bag, and it is not shifted, and re-uses cutter and presses line of cut cutting on the film bag; Three, the guide rail that a cutting knife is set and is complementary with cutting knife at a bar shaped platform is placed on the rectangular upper film bag of cutting that needs of plastic film bag on the guide rail, and film bag two ends adopt object to compress, and the line of cut of pressing on the film bag with cutting knife again cuts; But the shortcoming that the film bag is of poor quality and production cost is large that membrane efficiency is low, make is cut in existing of above several cutting methods.

In order to address the above problem, following patented technology has been proposed in the prior art:

China Patent No. " 02225300.9 " discloses a kind of film cutting apparatus of heat-shrinking plastic film packing machine, and its open day is on 09 25th, 2002, and this device includes be used to the cutting knife of cutting film, the rotor roller, block plate, location-plate, positioner are for two pairs of live-rollers that transmit film; Compare maximum different being from the film cutting apparatus of traditional up-and-down reciprocating, the cutting knife of this film cutting apparatus is timing rotation.Use this device to cut film, have the advantages such as the film of cutting is accurate, film feeding is steady, otch is neat, this film cutting apparatus also has the characteristics such as mechanical wear is little, long service life.
