Description
Technical field
The utility model relates to a kind of stretching device of producing polyester film, especially relates to the lax mechanism of the horizontal drawing device of a kind of low thermal shrinkage polyester film.
Background technology
The low thermal shrinkage polyester film is mainly used in electronic applications such as flexible print circuit board, thin film switch.Polyester film needs film is carried out longitudinal stretching and cross directional stretch in process of production, after thermal finalization is handled, film is relaxed, to reduce the shrinkage factor of film.Normally reach the lax purpose of film in the production equipment of polyester film at present by controlling guide rail width and heat treatment time and temperature, polyester film is after relaxing, laterally percent thermal shrinkage reaches smaller value, but vertically percent thermal shrinkage is not significantly descended, therefore make troubles for again the production and the processing of subsequent product to shrinkage factor is inconsistent in length and breadth, cause great influence also can for simultaneously the use of end product.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, economical and practical, under the prerequisite that does not influence horizontal percent thermal shrinkage, can reduce the lax mechanism of the horizontal drawing device of low thermal shrinkage polyester film of vertical percent thermal shrinkage.
The utility model is that the technical scheme that achieves the above object is: the lax mechanism of the horizontal drawing device of a kind of low thermal shrinkage polyester film, comprise guide rail, be arranged on the drive sprocket at guide rail two ends and by movable sprocket, with drive sprocket and two that are connected on the movable sprocket independently chain and two groups of films folders, it is characterized in that: described chain comprises outer plate, rebound and cylinder, the both sides of outer plate respectively by pivot pin and cylinder and be arranged on outer plate and cylinder between two rebounds hinged, the two adjacent rebounds and the directive wheel of bottom are hinged by connecting pin, and two groups of films folder is installed in respectively on the two adjacent outer plates and on guide rail; The lateral surface of described guide rail is provided with chimb, and directive wheel rolls with the chimb lateral surface and is connected.
The utility model by to drive sprocket with two that are connected by movable sprocket independently chain improve, make each carrier bar in the chain hinged by two adjacent rebounds of both sides respectively, make each carrier bar can be as a hinge unit, improve the flexibility of carrier bar, simultaneously owing to be provided with a chimb in the outside of guide rail, in chain drive film folder moves ahead, under the chimb effect of guide rail, pitch between adjacent two carrier bars is progressively dwindled, spacing between two groups of films press from both sides is also progressively dwindled, crystal habit and molecular chain orientation principle according to polyester film, it is fully lax that polyester film is all obtained at vertical and horizontal, and set and do not influence under the prerequisite of horizontal percent thermal shrinkage, can obviously reduce vertical contraction, make polyester film vertical, horizontal two to the shrinkage factor basically identical.The utility model can improve at common horizontal drawing device owing to simple in structure, and is therefore economical and practical.

The specific embodiment
See the lax mechanism of the horizontal drawing device of low thermal shrinkage polyester film shown in Fig. 1,2, the drive sprocket 1 that comprise guide rail 4, is arranged on guide rail 4 two ends with by movable sprocket, with drive sprocket 1 and two that are connected by movable sprocket independently chain 2 and two groups of films folders 5, chain 2 of the present utility model is two rotating for no reason chains, be fixed with two groups of film folders 5 on the chain 2, be used to clamp two edges of sheet material, and be supported on the guide rail 4 with by two chain 2 synchronous operations in the same way.See that chain of the present utility model 2 shown in Figure 3 comprises outer plate 21, rebound 22 and cylinder 24, the both sides of outer plate 21 respectively by pivot pin 23 and cylinder 24 and be arranged on outer plate 21 and cylinder 24 between two rebounds 22 hinged, and the directive wheel 3 of two adjacent rebounds 22 and bottom is hinged by connecting pin 6, this directive wheel 3 can adopt rolling bearing, and is installed on the connecting pin 6 by lining 27.See shown in Fig. 1,2 that two groups of film folders 5 are installed in respectively on the two adjacent outer plates 21, and the notch of film folder 5 is on guide rail 4, for reducing the wearing and tearing between rebound 22 and the connecting pin 6, see between adjacent two rebounds 22 shown in Figure 3 and the connecting pin 6 to be provided with anti-wear sleeve 26.Be similarly the wearing and tearing that reduce between cylinder 24 and the pivot pin 23, be provided with axle sleeve 25 between cylinder 24 and rebound 22 and the pivot pin 23, therefore each outer plate 21 is all as a hinge unit, and be connected with directive wheel 4 by rebound 22, make the course bearing operation of directive wheel 4 along guide rail, and the lateral surface of the utility model guide rail 4 is provided with chimb 41, directive wheel 3 rolls with chimb 41 lateral surfaces and is connected, chimb 41 on this guide rail 4 is that the two ends width is little, the chimb that broadens that the middle part width seamlessly transits greatly, by degree of broadening chimb, the pitch between two adjacent on the chain 2 outer plates 21 is changed.
See shown in Figure 4ly, when film folder 5 was positioned at chimb 41 ends of guide rail 4, because wide variety is less between two guide rails 4, directive wheel 3 rolled forward along chimb on the guide rail 41, and the pitch variation between adjacent two outer plates 21 is little at this moment, can not be lax fully; Directive wheel 3 rolls forward, along with the width on the chimb 41 increases, see shown in Figure 5, make the pitch between adjacent two outer plates 21 of junctional membrane folder 5 that bigger variation take place, be that 2 liang of chain link pitches of chain become the shortest, because the spacing between the two films folder 5 is to change in the film movement direction, thereby make film vertically obtain lax the contraction.
