For foregoing of the present utility model can be become apparent, preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:
Description of drawings
Figure 1A is the lateral plan according to the automatic deploying and retracting winding apparatus of a kind of hot press of the utility model preferred embodiment;
Figure 1B is the block diagram of the automatic deploying and retracting winding apparatus of Figure 1A;
Fig. 2 is that the automatic deploying and retracting winding apparatus of present embodiment is applied to the scheme drawing in the processing procedure.
The specific embodiment
Please refer to Figure 1A, Figure 1B, Figure 1A is the lateral plan according to the automatic deploying and retracting winding apparatus of a kind of hot press of the utility model preferred embodiment, and Figure 1B is the block diagram of the automatic deploying and retracting winding apparatus of Figure 1A.Automatic deploying and retracting winding apparatus 10 comprises the first feed element 110, the second feed element 120 and hot pressing mechanism 130.The first feed element 110 is provided with first coiled strip 112.The second feed element 120 is provided with second coiled strip 122, and wherein, the end of reel 112A of the volume of second coiled strip 122 122A and first coiled strip 112 has overlapping place, and this overlapping place is arranged in hot pressing mechanism 130.Hot pressing mechanism 130 makes a volume 122A of second coiled strip 122 engage with the end of reel 112A of first coiled strip 112 in order to provide thermal source and pressure to this overlapping place by this.
In addition, the first feed element 110 comprises roller bearing 114, and wherein, the first coiled strip circle is rolled up on roller bearing 114.The second feed element 120 comprises another roller bearing 124, and second coiled strip, 122 circles are rolled up on roller bearing 124.
Shown in Figure 1B, hot pressing mechanism 130 can be the electrothermic type engaging gear, for example is plug-in strip electrothermic type hot press.Hot pressing mechanism 130 comprises the first hot pressing die head 131 and the second hot pressing die head 133.The first hot pressing die head 131 and the second hot pressing die head 133 are provided with face-to-face, and can relatively move, and overlapping place of a volume 122A and end of reel 112A is between the first hot pressing die head 131 and the second hot pressing die head 133.Hot pressing mechanism 130 usefulness are so that predetermined temperature that should overlapping place is higher than the glassy state temperature of first coiled strip 112 and second coiled strip 122, and this predetermined temperature is lower than the fusing point of first coiled strip 112 and second coiled strip 122, makes the material of a volume 122A and end of reel 112A be transformed into glassy state gradually.
When the material of the volume 122A of overlapping place and end of reel 112A all was transformed into glassy state, the first hot pressing die head 131 and the second hot pressing die head 133 further applied pressure to a volume 122A and end of reel 112A, make the two fusion.Preferably, the 130 lasting schedule times of hot pressing mechanism provide thermal source and pressure to this overlapping place, and a volume 122A of second coiled strip 122 is engaged really with the end of reel 112A of first coiled strip 112.
The automatic deploying and retracting winding apparatus 10 of present embodiment is to see through the mode of hot pressing with the various bloomings of continuous production.Casehistory, (polyvinyl alcohol PVA) is example, and please be simultaneously with reference to Figure 1A, Figure 1B with the polyvinyl alcohol film in the making Polarizer.First coiled strip 112 and second coiled strip 122 respectively are the coiled strip of PVA film, and the width of two coiled strips is about 20 centimetres, a volume 122A of the end of reel 112A of first coiled strip 112 and second coiled strip 122 is corresponding up and down be arranged between the first hot pressing die head 131 and the second hot pressing die head 133 after, again heating and pressurizing to end of reel 112A with roll up a 122A.The heating power of hot pressing mechanism 130 is about 300 watts, but about 5 centimetres of pressing width, about 0.8 to 1.2 second of pressing time (the aforesaid schedule time).See through the temperature to roll up a 122A and end of reel 112A and bring up to more than the glassy state temperature, and be lower than fusing point, first coiled strip 112 and second coiled strip 122 can be fused into the bonding land of 5 centimetres of one section width.
In general, the processing procedure of PVA film is a wet process, if with the connect flooring of Acrylic Foam Tape as first coiled strip 112 and second coiled strip 122, because the PVA film has water-soluble, enter chemical liquids in the roller processing procedure after, Acrylic Foam Tape can't produce engaging force with face, that is first coiled strip 112 and second coiled strip 122 are joined together, in addition, oiliness or water paint can not engage the PVA film.If must use colloid as engaging interface, during through the roller pressing of roller processing procedure, the problem that pressure can cause colloid to overflow, and then pollute roller surface, and face also very likely forms rugged salient point, makes the face of product produce defective.
The automatic deploying and retracting winding apparatus 10 of present embodiment utilizes the thermoplastic or the thermoset nature of polymeric membrane, not only binding force is big after hot pressing, and when operating, wet process do not need additionally to use adhesive tape or coating etc., therefore can not produce problems such as above-mentioned excessive glue, salient point, make two coiled strips 112,122 form coating materials complete and that continuity is good, solve the problem that in the past can't unreel continuously in conjunction with the back.In addition, the automatic deploying and retracting winding apparatus 10 of present embodiment also can be applicable in the drying journey of roller certainly except can be applicable in the wet process.
Though above-mentioned hot pressing mechanism 130 is to explain with the electrothermic type engaging gear, so be not limited thereto, hot pressing mechanism 130 also can be high frequency engaging gear or ultrasonic engaging gear.
Then please refer to Fig. 2, it is applied to scheme drawing in the processing procedure for the automatic deploying and retracting winding apparatus of present embodiment.As shown in Figure 2, automatic deploying and retracting winding apparatus 10 also comprises automatic cutting knife 140, and it is arranged on the adjacent side of hot pressing mechanism 130.In addition, more be provided with in the processing procedure and hold cloth machine 200, in order to the speed that unreels of control coiled strip.When first coiled strip 112 (old coiled strip) is about to unreel when finishing, await orders in the top that makes second coiled strip 122 (new coiled strip) insert the second hot pressing die head 133.When confirming to want change of lap, hold 200 starts of cloth machine and make first coiled strip 112 in hot pressing mechanism 130, become quiescence, and make the first hot pressing die head 131 and 133 clampings of the second hot pressing die head with second coiled strip 122.Clamping strength can be 100 kilograms approximately, and the clamping time can go to be set at about 0.8～1.2 second or more was about 3 to 4 seconds according to process parameter.Drive automatic cutting knife 140 then and shift near first coiled strip 112 to cut first coiled strip 112.After the excision of old volume end (first coiled strip 112), blooming end to end promptly continuously, make each element involution position of holding cloth machine 200 and automatic deploying and retracting winding apparatus 10 again after, be original production state, can produce blooming continuously by this.Arrow A 1 place is the inlet of other processing procedures, enters the mouth as wet process.
In sum, though the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Have in the technical field under the utility model and know the knowledgeable usually, in not breaking away from spirit and scope of the present utility model, when doing various must the change and retouching.Therefore, protection domain of the present utility model is as the criterion when looking the claim scope person of defining.
