Description
The utility model belongs to the architecture advances of film conveying device in the film reader device.
At present in the exact instrument that uses forward and reverse film trasport; as film reader; the structure of its film conveying device has for receiving can; sprocket; film gate group etc.; now use this structure when unidirectional film trasport, film can keep accurate in locating, restarts after the shutdown; the film picture still can accurately be located; but when the reverse film trasport of needs, because the reverse stressed formation neutral gear of film just has film backlash phenomenon to occur; cause the location of film picture to produce error; thereby influence interpretation work, especially to high capacity, lengthy motion picture road film trasport more so; in this case; people can only use hand push button, progressively it are transferred to correct position, can normally carry out to guarantee interpretation work; yet forward film trasport once more need be adjusted again; it is very inconvenient that thereby the operation that makes the film interpretation seems, prolonged the interpretation time, reduced work efficiency.
The purpose of this utility model is to provide a kind of simple in structure, processing ease, can realize accurately location and do not have forward and reverse film conveying device of backlash of film picture.
Technical solution scheme of the present utility model is such, the basic structure of designed film conveying device is, be that the center is symmetrically arranged with a pair of receiving can that supplies with the film gate group, a pair of sprocket, characteristics of the present utility model are to be respectively arranged with compensation mechanism between sprocket and film gate group, wherein the structure of compensation mechanism has elasticity slide bar in axial sliding for device on the hold-down support of compensation mechanism, the outer end device of slide bar has the buffering pulley, stationary installation has electromagnet in the corresponding position of hold-down support and slide bar, its end face by slide bar is provided with the slide bar slide rail, the electromagnet energising can be fixed the slide bar adhesive, it can not be slided, and the adhesive face of slide bar is provided with armature, returning apparatus has spring on the elasticity slide bar, and the moment of return is arranged when slide bar is slided vertically.
Because the utility model adopts the position between a pair of sprocket and film gate group to be respectively arranged with two compensation mechanisms, control the locking and a sheet of loop pulley with electromagnet, that is to say, when the forward film trasport, electromagnet energising in the preceding loop compensation mechanism, make the elasticity slide bar be in locking state, back loop compensation mechanism is in elasticity and opens the sheet state, when reverse film trasport, back loop compensation mechanism originally changes preceding loop compensation mechanism into and makes slide bar be in locking state, and the loop compensation mechanism becomes post-compensation mechanism and makes the electromagnet power down before former, open the sheet state and make slide bar be in elasticity, so just eliminated the neutral gear spacing in time sheet, the film trasport phenomenon that in whole forward and reverse film trasport process, can not occur the film backlash by compensation, make the location of film can keep accurate in locating all the time, no longer need manual setting, guaranteed the fluency of film trasport, shortened the interpretation time greatly, improved work efficiency, particularly to high capacity, the film interpretation in lengthy motion picture road, effect is fairly obvious, and the utility model also has simple in structure in addition, characteristics such as applied range are to interpretoscope, developing and printing mechanism etc. all suits.
Accompanying drawing 1 is the position view of compensation mechanism in the designed forward and reverse film conveying device of the utility model, accompanying drawing 2 is the structural representation of an example of the designed compensation mechanism of the utility model, and accompanying drawing 3 is the structural representation of designed another example of compensation mechanism of the utility model.In the drawings, 1 for supplying receiving can, and 2 is sprocket, and 3 is film, and 4 is compensation mechanism, and 5 is the film gate group, and 6 is hold-down support, and 7 is the manual locking screw, and 8 is armature, and 9 is the elasticity slide bar, and 10 are the buffering pulley, and 11 is spring, and 12 is electromagnet.
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1 and Fig. 2, designed forward and reverse film conveying device is to be the center with film gate group 5, is symmetrically arranged with a pair ofly for receiving can 1, and a pair of sprocket 2 is respectively arranged with compensation mechanism 4 between sprocket 2 and film gate group 5.Wherein the structure of compensation mechanism is that device has elasticity slide bar 9 in axial sliding on a hold-down support 6, the outer end of slide bar 9 is provided with buffering pulley 10, slide bar 9 in the hold-down support is provided with spring 11, one end of spring is fixed on the slide bar, the other end is fixed on the bearing, the moment that return is arranged when slide bar is slided vertically, corresponding position at hold-down support 6 and slide bar 9 is fixed with electromagnet 12, its end face by slide bar 9 is provided with the slide bar slide rail, slide bar 9 adhesives can be fixed after electromagnet 12 energisings, it can not be slided, and in order to increase the adhesive effect of slide bar, the adhesive face of slide bar 9 is provided with armature 8.During the interpretation film, film is from supply can output 1, through sprocket 2, compensation mechanism 4 and film gate group 5, again through opposite side compensation mechanism 4, sprocket 2 to receiving can 1 is finished film trasport work, wherein when film process compensation mechanism 4, because the effect slide bar 9 of spring 11 slides in bearing 6 vertically, the film on the pulley fluctuates with slide bar with the variation of its tensile force, makes film obtain tensioning.When work, the compensation mechanism 4 of film working direction rear end is in elasticity and opens the sheet state, and its pulley can fluctuate, and electromagnet 12 becomes fixed block with slide bar 9 adhesives in the compensation mechanism of front end, compensation mechanism 4 is in locking state, to guarantee the accuracy of film location.
Referring to Fig. 3, designed compensation mechanism is that device has the elasticity slide bar 9 that can slide vertically on hold-down support 6, the epimere of slide bar is with spring 11, the spring lower end is fixed with pin, the moment that when slide bar 9 slides vertically, has return, the outer end device of slide bar has buffering pulley 10, hold-down support 6 is provided with electromagnet 12 with slide bar 9 corresponding positions, its end face by slide bar is provided with the slide bar slide rail, the slide bar adhesive can be fixed after electromagnet 12 energisings, it can not be slided, and on the adhesive face of slide bar 9, be provided with armature 8.When film passes through compensation mechanism, electromagnet 12 becomes fixed block with the slide bar adhesive in the front-end compensation mechanism, compensation mechanism 4 is in locking state, then because spring 11 acts on pulley 10 is fluctuated in the end compensating mechanism, compensation mechanism 4 is in elasticity and opens the sheet state and guarantee the film accurate positioning, to realize no backlash film trasport.
In order to solve sometimes easy to operate, the utility model hold-down support 6 is provided with manual locking screw 7, can lock the elasticity slide bar, stops its slip.The compensation mechanism that the utility model is designed is taked computer control or instrument to control when forward and reverse film trasport of film conveying device switches and is automaticallyed switch, but also manual switchover in case of necessity.
