Abstract

The utility model relates to a cylinder like double surface continuously embossing (by rolling or pressing) apparatus for a plastic film. The cylinder like double surface continuously embossing (by rolling or pressing) apparatus for a plastic film is an embossing (by rolling or pressing) apparatus which is used for reprocessing the plastic film in the plastic processing machinery. The utility model is composed of a belt pressing and regulating device, four flexible backing rolls which are installed on the support frame of a cut-in frame, and a suspended embossing mould core which is clamped and fixed in the middle. The utility model solves the cylinder like double surface continuously embossing (by rolling or pressing) problem for long and coiling plastic films. The machinery and method that the consistent patterns which are convex from inner to outer are formed by embossing (rolling or pressing) once on the cylinder like plastic film is provided. After the embossing (rolling or pressing) of the cylinder like plastic film is carried out, the heavy packaging bag is made, and the heavy packaging bag has anti-slip effect, and anti-falsification and decorative functions.

Description

Cylinder like double surface continuously embossing (by rolling or pressing) apparatus for plastic film

Two-sided (pressure) embossing device that rolls continuously of the tubular plastic foil that the utility model relates to belongs to plastic processing machinery, is that International Classification of Patents belongs to the B29C59/04 class to the refabrication plant of plastic foil with the roll-in flower exactly.

Surface Machining-the embossing of plastic foil at present, embossing is many to carry out on dull and stereotyped single face, what have also need finish embossing by heating, though what have suppresses decorative pattern with roller, but just the individual layer sheet plastic foil to rolling carries out continuous embossing, tubular plastic foil to rolling carries out two-sided continuous roll extrusion by consistent protruding outside decorative pattern in the tube, then can not implement, even post forming can not be finished.Through in the technology of domestic present enforcement from the retrieval of chemical industry department with through the detailed search of patent documentation, domestic do not have this technology extremely, No. 85104217.1 " embossing calender for thermoplastic sheet " its structures of the most close Chinese invention patent are, can carry out double-sided embossing to plastic foil, but can not once finish, and the equipment complexity involves great expense, and can not carry out once to extrude continuously by consistent cambered outwards decorative pattern in the tube the very long tubular plastic foil of rolling is two-sided.Event is spent technology and is installed this problem for the two-sided continuous roll extrusion of the tubular plastic foil that chemical industry proposes, and domestic still nobody finishes.

The purpose of this utility model is to finish the two-sided continuous roll extrusion flower technical task of tubular plastic foil that chemical industry proposes, provide a kind of simple and practical can to the tubular plastic foil of rolling two-sided once roll out continuously consistent protruding outside tube the decorative pattern of (or interior), to realize the effects such as anti-skidding, false proof and decoration of heavily packaging bag.

The utility model is realized by following scheme: be placed on floated annular knurl core rod in the tubular plastic film tube every (or about) about the tubular plastic foil two individual layers by one, be clamped on four bearing rollers, add certain pressure with support and fix four bearing rollers, the floated annular knurl core rod of indirect securement, about bearing roller divides or two groups up and down, wherein an end spindle nose of one group is equipped with synchromesh gear, and refute and connect power, two mesomerism gears are arranged between two synchromesh gears, to guarantee to be equipped with two bearing roller running speed unanimities of synchromesh gear, direction is opposing, the place ahead of support is established the incision frame and introduced plastic foil, and tractive and apparatus for shaping are established in the rear.Bearing roller is that flexible high molecular material is made, the adjustable bearing roller of clamping adjustment device is to the pressure of core rod, make it to turn round and steadily reach the depth degree of adjusting the embossing lines, floated annular knurl core rod connects two colored rollers by a framework and forms, be not equipped with power, flower roller pattern can be various, can be sour jujube shape, concavo-convex, literal etc. as required, has two little pair rollers in plane on the incision frame.More than device can one of them be exchanged with every group of bearing roller with the flower roller, can change the concave and convex direction of suppressing decorative pattern, suitable different needs.

Advantage of the present utility model is: can carry out continual two-sided (pressure) decorative pattern that rolls continuously to the very long tubular plastic foil of rolling, and once finish, and simple in structure, working stability, easy to operate, flexible, utility model, its product focus on making heavily packaging bag to have skidproof effect, also produce false proof and decoration function simultaneously, also can carry out the embossing processing to other tubular and slice plastic film, except that producing above effect, also play scattered beam and prevent reflectively, effect such as shut out the light.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1: cross-sectional view of the present utility model

The A of Fig. 2: Fig. 1 is to view

1. support 2. flower rollers 3. frameworks 4. power bearing rollers 5. unpowered bearing roller 6. clamping adjustment devices 7. are cut framves 8. tubular plastic foils 9. little pair roller 10. synchromesh gears 11. mesomerism gears

The utility model is to grip a floated annular knurl core rod about 5 minutes in the middle of two groups by two power bearing rollers 4 and two unpowered bearing rollers, be installed on the support 1 and constitute, the left end of support 1 is by two vertical grooves, install and fix the spindle nose at two power bearing rollers 4 and two unpowered bearing rollers, 5 two ends respectively, four clamping adjustment devices 6 in top are adjusted the pressure of bearing roller to floated annular knurl core rod, change the depth degree of embossing, right-hand member is equipped with the incision frame 7 with two little pair rollers 9 in plane, to introduce tubular plastic foil 8, bearing roller is made (as rubber) by flexible high molecular material, floated annular knurl core rod is connected up and down by a framework 3 two spends rollers 2 to form, flower roller 2 is made by hard material, decorative pattern on it can be made various patterns as required, literal, the sour jujube shape, concavo-convex, literal etc., two set on synchromesh gear 10 and the support 1 mesomerism gears, 11 engagements are housed on the one end spindle nose of two power bearing rollers 4, make two power bearing roller 4 synchronous backwards rotation up and down, move with speed to protect the two-layer up and down of tubular plastic foil 8.The plastic foil 8 of the tubular of rolling is by the direction of arrow shown in Figure 1 during work, little pair roller 9 on incision frame 7 is introduced, dividing up and down, two individual layers are pressed in respectively between colored up and down roller 2 and the bearing roller, floated annular knurl core rod was suspended by four bearing rollers every plastic foil and was fixed in the tubular plastic foil 8 this moment, make colored roller 2 can not about, about, move forward and backward, but can be with the rotation of bearing roller, moving continuously of tubular plastic foil 8 and rotating, simultaneously on film two-sided suppress consistent, continual decorative pattern, the protruding from inside to outside sour jujube shape decorative pattern of two row continuous uninterrupted is arranged on the tubular plastic foil 8 that it processes, can produce fabulous skidproof effect with this heavily packaging bag of making.One of them is refuted and connects power on the synchromesh gear 10.
