Description

Seven roller plastic calenders

One, technical field:

The utility model relates to plastic calender, particularly discloses a kind of seven roller plastic calenders, is applied in the above plastic sheet of compacting thickness 1mm and 1mm, and its transparency of the quality of sheet and shaping quality are also brighter than glass plate.

Two, background technology:

The present equipment of China's plastic cement rolled products industry all is three more than 95%, produce on the four-roll calender, wherein the import equipment over past ten years is also stereotyped is four-roll calender, the equipment 90% of Taiwan enterprise also is four-roll calender, the high-grade hard sheet of plastic, transparent of compacting on four roller machines, no matter great machine, the sheet material that is pressed into 0.6mm thickness is very difficult, the above sheet of compacting 0.6mm begins to contain a large amount of bubbles, and transparency begins to send out mist, its product becomes goods of inferior quality or inferior waste product, the Chinese patent ZL00216467.1 five roller plastic calenders that the inventor obtains also can only be pressed into the 0.8mm sheet, and current market is still scarce to be pressed into more than the 0.8mm even the equipment of 1.5mm sheet.

Three, summary of the invention:

Technical problem to be solved in the utility model is a kind of novel plastic calender of design, can suppress the above sheet of 1mm, and can make its transparency of sheet quality and shaping quality also brighter than glass plate.The utility model is to realize like this, design provides a kind of seven roller plastic calenders, mechanism comprises casing, running roller, power motor, travelling gear, roll adjustment and electrical control gear, it is characterized in that: described running roller has seven, from feed roller (1), roller (2) is placed in the side of roller (1), roller (3) is in roller (2) below, roller (4) is at roller (3) side, all the other rollers (5), (6), (7) successively in roller (4) below, the track of seven running roller axial connecting lines on the same cross section (i.e. the spread pattern of seven running rollers) is the M type, and described M type is arranged can positive M type or tiltedly M type arrangement.The running roller spread pattern of calender relates to the superior technical matters performance of the highly difficult and plastics calendering production demand of machine industry, the M type of seven running rollers is arranged, the sizing material that has plastified is from 1#, the 2# wheel drops into and rolls, its sizing material is to 2#, 3#, the bag roll surface of 4# all is 1/4th, here significantly reduced the time that air contacts with sizing material, also reduced the temperature difference of sizing material length direction, and prevent that sizing material from being moved about toward the centre by both sides, and the tendency that produces the ripples line, secondly as shown in drawings, seven roller machines have carried out five calenderings to sizing material and have sheared, its sizing material only is 2 times of running roller face to the cornerite face of running roller, and arrange four L shaped roller machines sizing material is carried out 3 calendering shearings, but its bag roll surface also will reach 1.5 times, obviously M type seven roll calendars have promptly reached the effect of sizing material being carried out the multiple roll continuous calendering, have significantly reduced the time that sizing material contacts with air again, therefore have very strong eliminating steam bubble ability.

The utility model has the advantages that: 1) owing to adopt seven roll-ins to prolong, this machine compact conformation, the principle that the calendering of continuous five roads is sheared to sizing material, therefore, following superior characteristics are arranged under same technical recipe condition, sizing material is plastified, help dissolving the particle that some are difficult for plasticizing, thereby significantly reduce the brilliant point on the rolled products; 2) it is strong to get rid of the steam bubble ability, can suppress the sheet of 0.8mm～1.2mm that four, five roll calendars can't suppress; 3) rolled products surface brightness, transparency are good, are that the rolled products institute of four, five roll calendars is too far behind to catch up; 4) help eliminating the ripples line of product surface, because adopt seven roll-ins to prolong, the speed ratio adjustability between the running roller is strong, the time that the while sizing material contacts with air significantly reduces, farthest reduce temperature to the sizing material Temperature Influence, thereby significantly reduced the generation of product surface ripples lines; 5) adopt seven roll calendars in supporting leading portion plasticizing equipment, can save two roller plastics processing mills, reduce by 3 operators relatively, simultaneously can save electric power charge, the M type seven roll calendars statistics of trailing wheel footpath, wheel face width Φ 400 * 1000mm, can be enterprise every year and save 22.416 ten thousand yuan, economic benefit, social benefit are very valuable; 6) production capacity height, seven roll calendars improve 40% than traditional four-roll calender speed of production, also will improve 20% than the production short-term training degree of five roll calendars.

With Figure of description the utility model is further illustrated below:

Four, description of drawings:

Accompanying drawing 1 is the utility model running roller arrangement architecture schematic diagram.

Accompanying drawing 2 is the input and output material processing schematic diagram of embodiment 1.

Accompanying drawing 3 is the input and output material processing schematic diagram of embodiment 2.

Five, the specific embodiment:

Embodiment 1: with reference to the accompanying drawings 1, seven running rollers are arranged in eurymeric M type form, roller (4), (5), (6), (7) be arranged on the same vertical line, the slice of seven rollers is in the horizontal plane direction, described running roller periphery has close and the (not shown) of holing uniformly, this structure remains constant temperature down in working order to running roller and obtains assurance, advanced defibrator process technology is adopted in the grinding of pair roller wheel surface, can eliminate the thermal deformation under the running roller heated condition, more than the roughness Ra0.02 on running roller surface (13 grades of fineness), also dispose numeric display unit and anti-collision roller arrangement on the running roller roll-setting gear, debugging operations in being convenient to produce, PLC communication interface (not shown) is all held in the electrical control of calender, whole piece calendering line is all controlled by PLC, and can enter the user computer network, the PLC technology has been known technology, needn't describe in detail.The model specification of seven roller plastic calenders can be selected in wheel face width 900mm～4000mm scope at wheel footpath φ 300mm～φ 1000mm.

Embodiment 2, and 1 seven running rollers are arranged in oblique M type with reference to the accompanying drawings, and roller (4), (5), (6), (7) are arranged on the angled straight lines, and the slice of seven rollers is in an inclined plane direction, and all the other are identical with embodiment 1.Embodiment just illustrates a kind of way of realization in the technical scheme, does not limit to the utility model protection domain, and the novel protection of this realization embodies in the claims.

The brilliance of the significantly superior and article of manufacture quality of the utility model production capacity has become a jewel on the sector, applies and will obtain big social benefit of tool and economic benefit.
