Description
Technical field
The utility model belongs to rubber equipment technical field, is specifically related to a kind of band ejecting structure use for laboratory rubber pelletizing cutting die.
Background technology
The rubber plastic blend type thermoplastic elastomer (TPE) for formulating prepared in laboratory can adopt the equipment such as small-sized internal mixer and extruder to process, in order to obtain excellent performance and be easy to process intermingling material, usually first rubber or the elastomeric compound that adds various compounding ingredient can be cut into the particle suitable with plastic grain size, and then and plastic blend.Because the quality of each rubber used by formula used or elastomeric compound is less in experiment; but formula number is more; industrial used large-scale rubber pelleter is difficult to carry out cutting of a small amount of rubber and the cost of machine is higher; if with manually cutting out, the size heterogeneity of its micelle and comparing expends time in, energy.
Summary of the invention
The utility model provides a kind of low cost of manufacture, in use conveniently can carry out the band ejecting structure use for laboratory rubber pelletizing cutting die that the rubber of a small amount of, polygamy side or elastomeric compound cut.
Technical solutions of the utility model realize by the following method:
A kind of band ejecting structure use for laboratory rubber pelletizing cutting die, comprise pressure plate, slotting tool sheet, described pressure plate upper surface middle part offers foursquare groove I, pressure plate four limit is the platform that width is identical, described groove I place offers several through holes I be evenly distributed, described pressure plate bottom, " L " shape jack is offered between every two row through holes I, described slotting tool sheet is inserted in jack, bolt is interspersed with downwards from groove I in described each through hole I, bolt bottom is fixedly connected with elastomeric element by screwing of nut, the spring members lower end of each row described is fixedly connected with one and ejects rod, also comprise base, in the middle part of described base upper surface, offer the groove II identical with groove I shape.
As further improvement of the utility model, described groove II inside is placed with at least one piece of backing plate fitted tightly with groove II surrounding, and object is to protect slotting tool sheet.
Further improve as of the present utility model, described groove II bottom offers at least one through hole II, is conveniently ejected from groove II by the one or more backing plates be placed therein.
Described elastomeric element when nature, eject rod bottom with slotting tool sheet bottom on sustained height.
The beneficial effects of the utility model are:
1, slotting tool sheet is inserted in pressure plate by pressure plate bottom L shape jack, can change at any time if insert breaks down; With the ejecting structure of elastomeric element, the damage ejecting rod if there is elastomeric element or bottom can directly be changed, and is conducive to improving experimental facilities practicality, saving experimental facilities cost;
2, by the effect of ejecting structure, the friction between rubber and slotting tool sheet can be overcome, the rubber strip cut, rubber grain are easy to be separated with slotting tool sheet under the effect of ejecting structure, through level, cut for vertical twice, can obtain the rubber grain that size is more homogeneous.

Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1 to Figure 3, a kind of band ejecting structure use for laboratory rubber pelletizing cutting die, comprise pressure plate 1, slotting tool sheet 2, pressure plate 1 upper surface middle part offers foursquare groove I 1a, pressure plate 1 four limit is the platform 1b that width is identical, groove I 1a place offers several through holes I 8 be evenly distributed, through hole I 8 is distributed as 3 row 6 and arranges totally 18, pressure plate 1 bottom, " L " shape jack is offered between every two row through holes I 8, slotting tool sheet 2 is inserted in jack, bolt 3 is interspersed with downwards from groove I 1a in each through hole I 8, bolt 3 bottom is fixedly connected with elastomeric element 5 by screwing of nut 4, spring members 5 lower end of each row is fixedly connected with one and ejects rod 6, in use procedure, if slotting tool sheet 2 damages and can change at any time, be conducive to improving experimental facilities practicality, save experimental facilities cost, pressure plate 1, slotting tool sheet 2 is high-speed steel material, there is high strength, high-wearing feature, the feature of high-fire resistance, elastomeric element 5 adopts spring, ejecting rod 6 is strip or the cylindrical rod that ejects, its material is vulcanie or plastics, eject excellent 6 length consistent with the length of slotting tool sheet 2, eject rod 6 wide or eject the distance that excellent 6 diameters are slightly less than two slotting tool sheets 2, spring is when nature, eject rod 6 bottom with slotting tool sheet 2 bottom on sustained height, also comprise base 7, base 7 adopts stainless steel to make, base 7 upper surface middle part offers the groove II 7a identical with groove I 1a shape, groove II 7a inside is placed with at least one piece of backing plate 10 fitted tightly with groove II 7a surrounding, backing plate 10 adopts polypropylene material, its objective is to protect slotting tool sheet 2, groove II 7a bottom to offer a through hole II 9, conveniently the one or more backing plates 10 be placed therein being ejected from groove II 7a.
During use, rubber or the elastomeric compound that mixes are placed in mill bag roller, treat smooth surface bubble-free, bottom sheet.This rubber or elastomeric compound film are sheared, its length of side is slightly less than the length of slotting tool sheet 2, and shape is preferably square.First one or more backing plate 10 is placed in the groove II 7a of base 7, the selection of the quantity of backing plate 10 will be determined according to the thickness of film.Film be placed in the middle part of the groove II 7a of base 7 and be positioned on backing plate 10, then the slotting tool sheet 2 held together and ejecting structure being put on sheet rubber, in base 7 groove II 7a.The upper limb ejecting rod 6 is on sustained height lower than the upper surface of base 7 or both.Film pelletizing adopts two step operations, multiple slotting tool sheets 2 of band ejecting structure to be directly pressed on sheet rubber and to be placed in base 7 by the first step, sheet rubber is cut into strip by the effect by sheet-punching machine, when then taking out slotting tool sheet 2, direct under the action of the spring the rubber strip cut to be ejected between slotting tool sheet 2 or between the inwall of slotting tool sheet 2 and base 7 groove II 7a.Second step, by multiple slotting tool sheets 2 of band ejecting structure to be pressed on sheet rubber after 90 degree rotations and to be placed in base 7, now the rubber strip that cuts of slotting tool sheet 2 and the first step is perpendicular, relends and helps the effect of sheet-punching machine rubber strip can be cut into the more homogeneous rubber grain of size.
