Abstract
The utility model relates to an automatic film transmitting apparatus, in particular to an automatic film transmitting apparatus with fixed length and constant tension, which comprises a linearly reciprocating moving cylinder (13), a film pressed cylinder (17), a film transmitting motor (18) and a gravity tension device consists of a gravity tension roll (14), a linear bearing (15) and a guide rail (16), wherein a film drawing frame (19) is arranged on the linearly reciprocating moving cylinder (13), the film pressed cylinder (17) is arranged on the film drawing frame (19). Compared with the prior art, the utility model has the advantages of fixed length feeding, constant tension of the film, simple structure, easily realized controlling, and better reliability of the whole apparatus.
Description
Technical field
The utility model relates to a kind of automatic film feeding mechanism, the automatic film feeding mechanism of the permanent tension force of particularly a kind of measured length.
Background technology
Automatic film feeding mechanism of the prior art, the first adopts two belts (1) to compress film (or band) (2), utilize the move distance of servomotor (3) control belt to realize measured length film feeding (or band), adopt tension wheel (4) and tensioning spring (5) and tension pick-up (6) to realize approximate permanent Tension Control (as shown in Figure 1) simultaneously; It two is to adopt two rollers (7) to compress film (or band) (8), utilize the rotational angle of servomotor (9) control roller to realize measured length film feeding (band), adopt tension wheel (10) and tensioning spring (11) and tension pick-up (12) to realize approximate permanent Tension Control (as shown in Figure 2) simultaneously.There is following weak point in it:
1. film feeding length is non-constant: owing to compress by two belts or two rollers, often change film feeding length because of slipping of the belt or rolling wheel wear in the work;
2, the tension force of film is non-constant and influence film feeding length: at work, the tensile force of film is controlled by the tensioning spring tensile force, and being position change with tension wheel, the tensile force of tensioning spring changes, when tension wheel makes progress, tensioning spring is stretched as increase, otherwise then reduce, so influence film feeding length;
3, complex structure, the control difficulty is bigger, and whole aircraft reliability is not strong: because its power element adopts is expensive element and vulnerable parts such as belt pulley or roller such as servomotor, pressure sensor, so reliability is not strong, complex structure, the control difficulty is bigger.
Technology contents
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide the permanent tension force of a kind of measured length automatic film feeding mechanism.
The technical solution of the utility model is: the automatic film feeding mechanism of the permanent tension force of measured length includes straight reciprocating motion apparatus, gravity tensioning device, mould is tightly installed and the film feeding motor, the gravity tensioning device is made up of idler roller, linear bearing and guide rail, idler roller is installed on the guide rail by linear bearing and can makes the straight line up-and-down movement thereon, and the tight device of mould is installed on the membrane frame of straight reciprocating motion apparatus.
The further technical scheme of the utility model is: straight reciprocating motion apparatus is cylinder or slide rail.
The utility model further technical scheme is: the tight device of mould is cylinder or electromagnet.
The utility model compared with prior art, has following advantage owing to adopt as above design:
1, the measured length feed length is constant: do not exist in the prior art because of slipping of the belt or rolling wheel wear to change feed length;
2, the constant tension of film: because the suffered tension force F=G/2 of film, can not influence the suffered tension force of film because of film feeding motor start-stop, G=mg, can not change because of the position change of idler roller, in case the tension change of film at work, then the pulling force of membrane also can change thereupon during feeding, can not influence the length of film feeding;
3, simple in structure, control realizes that easily the entire mechanism good reliability: the employed power element of the utility model is general part, so whole aircraft reliability is strong, simple in structure, control easily realizes.
Description of drawings
Accompanying drawing 2 is the structural representation of the existing automatic film feeding mechanism of roller type;
Accompanying drawing 3 is a structural representation of the present utility model;
Accompanying drawing 4 is the structural representation of gravity tensioning device of the present utility model;
Below in conjunction with drawings and Examples detailed structure of the present utility model is described further.
As shown in drawings: gravity tensioning device (as shown in Figure 4), the tight cylinder of mould (17) and film feeding motor (18) that the automatic film feeding mechanism of the permanent tension force of measured length includes straight reciprocating motion cylinder (13), is made up of gravity tensioning roller (14), linear bearing (15) and guide rail (16), membrane frame (19) is arranged on the straight reciprocating motion cylinder (13), and the tight cylinder of mould (17) is installed on the membrane frame (19).
When the gravity tensioning roller (14) on the tightening device when being in lowest part, film feeding motor (18) stops operating, and the membrane frame (19) on the straight reciprocating motion cylinder (13) moves right, and the tight cylinder of mould (17) compresses film (20), to left movement, realize the measured length film feeding then; Simultaneously, when the gravity tensioning roller (14) of tightening device when leaving lowest part, film feeding motor (18) beginning film feeding.So circulation, the tension force of film is constant all the time.
