Abstract
The utility model discloses a die head hoisting mechanism on an EVA (ethylene vinyl acetate) adhesive film extruding machine, which is characterized by comprising a hoisting cross beam and at least two hoisting hoists, wherein the hoisting cross beam is arranged on a machine frame, positioned above a die head and is placed in parallel with the die head; hanging pieces are respectively arranged at two ends and in the middle of the hoisting cross beam, and a hanging hole is formed in each hanging piece; upper lifting hooks matched with the hanging holes are arranged at top ends of the hoisting hoists; and hoisting hooks of the hoisting hoists are matched with hoisting rings on the die head. According to the utility model, the hoisting cross beam and the hoisting hoists are arranged so as to realize the hoisting of the die head, a traveling crane is not needed, the operation is more convenient, and the use cost is reduced.
Description
Technical field
The utility model relates to the die head hoisting mechanism on a kind of EVA glued membrane production facilities annex, particularly a kind of EVA glued membrane extruder.
Background technology
If solar cell directly is exposed in the air, its photoelectric transformation efficiency can descend very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the purpose that is isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and have elastomeric ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with the levels protective material, consist of solar module.
EVA is a kind of typical random high molecular compound, in its molecular structure, the irregular arrangement of substituent on strand, the configuration of unsymmetrical carbon is not identical yet in the strand simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of elasticity, it has good wellability when heating and melting in addition, having good flexibility, anti-stress cracking and adhesive property during cooling curing, is a kind of comparatively desirable material that can be used for solar cell package.
What the EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, side cut unit and winding device, finishes batch mixing, material loading, extrudes, moulding, side cut, winding process.Wherein, extrusion equipment is a step of most critical in the whole process, directly finish and put into extruding of finished product from raw material, extrusion equipment mainly is made of the die head of extruder and extruder front end, described die head is made of forward and backward cope and drag pattern tool and left and right end cap amalgamation, the die head top is lifted on by support on the frame of extrusion device, and the bottom is extrusion, and raw material is from then on to be extruded the casting film-forming shape.
Die head, is needed by the driving lifting, otherwise die head and support can't be connected and fixed about 1～2 ton by the weight of whole die head when mounted, so makes troubles to EVA rubber moulding manufacturer.Need the driving lifting except installing, die head in use for some time, all need to split and clean, when splitting, again by the lifting of driving a vehicle, so driving becomes the prerequisite equipment of EVA rubber moulding manufacturer, and need to be equipped with the navigating mate of driving, the working service that has improved the EVA manufacturing line requires and cost.
Summary of the invention
For the technical matters of above-mentioned existence, the purpose of this utility model is: proposed the die head hoisting mechanism on a kind of EVA glued membrane extruder, by the improvement of structure, be convenient to installation and fractionation to die head, reduced the input of use cost.
Technical solution of the present utility model is achieved in that the die head hoisting mechanism on a kind of EVA glued membrane extruder, comprise that a lifting cross beam reaches at least 2 liftings and uses cucurbit, described lifting cross beam is arranged on the frame, be positioned at the top of die head, and being parallel to described die head arranges, two ends and the centre of described lifting cross beam are respectively equipped with suspension member, and each described suspension member is provided with hanging hole; Described lifting is provided with the hook that cooperates with hanging hole with the cucurbit top, the lifting hook of lifting usefulness cucurbit cooperates with the suspension ring on the described die head.
In the technique scheme, the suspension member at described lifting cross beam two ends lays respectively at the top of the left and right end cap of die head.
In the technique scheme, described lifting is chain block with cucurbit.Can adopt chain block of the prior art, its principle of work is: pull chain-driving driver pinion rotation, miniature gears drives big gear wheel and rotates, and with the moment output of having amplified, thereby slings weight.In the inboard that pulls chain a ratchet and pawl arrangement is arranged, sprocket wheel can only a direction be rotated.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
1, in frame lifting cross beam is set in the utility model, cooperate with cucurbit with lifting by the suspension member on the lifting cross beam, realize the lifting to die head, so just can save using and being equipped with of driving, reduce the use cost of EVA rubber moulding manufacturer, and simple to operate.
2, lifting is taken off under unused state with cucurbit, is hung on during use and hangs on the crossbeam, does not therefore affect the operations of operating personal in EVA rubber moulding production process, and is flexible and convenient to use.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the use status architecture schematic diagram among the utility model embodiment one;
Fig. 2 is the birds-eye view (die head does not draw) of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cross-sectional schematic.
Wherein: 1, die head; 2, lifting cross beam; 3, cucurbit is used in lifting; 4, frame; 5, suspension member; 6, lifting hook; 7, suspension ring; 8, pull chain.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples:
Embodiment one: shown in Fig. 1～3, die head 1 hoisting mechanism on a kind of EVA glued membrane extruder, comprise a lifting cross beam 2 and 3 liftings usefulness cucurbits 3, described lifting cross beam 2 is arranged on the frame 4, be positioned at the top of die head 1, and be parallel to described die head 1 layout, the two ends of described lifting cross beam 2 and centre are respectively equipped with suspension member 5, the suspension member 5 at left and right two ends lays respectively at the left and right end cap top of die head 1, and each described suspension member 5 is provided with hanging hole; Described lifting is provided with the hook that cooperates with hanging hole with cucurbit 3 tops, and the lifting hook 6 of lifting usefulness cucurbit 3 cooperates with the suspension ring 7 on the described die head 1.
In the present embodiment, described lifting is chain block with cucurbit 3.As shown in Figure 1, in use, on the suspension member 5 of lifting cross beam 2 two ends and centre, hang respectively one and pull cucurbit, lifting hook 6 on the chain block cooperates with suspension ring 7 on the die head 1, pulling pulls chain 8, drives the driver pinion rotation, and miniature gears drives big gear wheel and rotates, with the moment output of having amplified, thereby sling die head 1.In the inboard that pulls chain 8 ratchet and pawl arrangement is arranged, sprocket wheel can only a direction be rotated, prevent that counter-rotating from occurring unexpected.In the time need to lifting the left and right end cap at die head 1 two ends, also can only use 2 chain blocks, respectively to left and right end cap lifting, use flexible, convenient.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
