Abstract
The utility model discloses a kind of hyaline membrane and lay feed mechanism, comprise stay bearing plate, also comprise brake collar and retarding spring, described stay bearing plate is provided with for rotating shaft that is fixing and support hyaline membrane reel, in described rotating shaft, fixed cover is connected to brake disc, movable sleeve is connected to hold-down arm, described hold-down arm is provided with two rollers of arranging up and down, one end of described retarding spring is fixedly connected with on the supporting plate and the other end is connected to the end of hold-down arm, one end of described brake collar connects on the supporting plate and the other end is connected to the end of hold-down arm, described brake collar is wound around on the disc brake rotor.The purpose of this utility model is to provide a kind of hyaline membrane of the plastic film of accurate size that can provide and lays feed mechanism.
Description
Technical field
The utility model relates to packing Fabricating machinery field, and particularly a kind of hyaline membrane lays feed mechanism.
Background technology
Coated one deck plastic film is generally wanted in the surface of packing box, and the size of plastic film should control accurately, in order to avoid excessive packaged by plastic film produces fold on packing box surface.
Therefore in plastic film supply equipment, need the mechanism that installation one can make plastic film be in tight state, such cutting mechanism just can cut accurately.
Utility model content
The purpose of this utility model is to provide a kind of hyaline membrane of the plastic film of accurate size that can provide and lays feed mechanism.
The technical scheme that the utility model provides is: a kind of hyaline membrane lays feed mechanism, comprise stay bearing plate, also comprise brake collar and retarding spring, described stay bearing plate is provided with for rotating shaft that is fixing and support hyaline membrane reel, in described rotating shaft, fixed cover is connected to brake disc, movable sleeve is connected to hold-down arm, described hold-down arm is provided with two rollers of arranging up and down, one end of described retarding spring is fixedly connected with on the supporting plate and the other end is connected to the end of hold-down arm, one end of described brake collar connects on the supporting plate and the other end is connected to the end of hold-down arm, described brake collar is wound around on the disc brake rotor.
Lay in feed mechanism at above-mentioned hyaline membrane, the surface of described rotating shaft is fixedly connected with drum sheath, and the two ends of described drum sheath are provided with and are locked cover for blocking described hyaline membrane reel.
The utility model is after employing technique scheme, and its beneficial effect had is:
(1) cooperatively interacted by retarding spring, brake collar, limit the velocity of rotation of brake disc be fixedly connected with rotating shaft, axis of rotation speed can be avoided like this to differ the supply of the plastic film caused problem different in size.
(2) surface of rotating shaft is fixedly connected with drum sheath and arranges the cover that is locked at drum sheath two ends and can fix hyaline membrane reel and discharge hyaline membrane in specific position by actv., places hyaline membrane reel and discharges in process and swing arbitrarily.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model embodiment 1;
Fig. 2 is the lateral plan of the utility model embodiment 1.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but does not form any restriction of the present utility model.
Embodiment 1:
As shown in Fig. 1 to 2, a kind of hyaline membrane lays feed mechanism, comprise stay bearing plate 1, also comprise brake collar 2 and retarding spring 3, described stay bearing plate 1 is provided with for rotating shaft 4 that is fixing and support hyaline membrane reel, in described rotating shaft 4, fixed cover is connected to brake disc 5, movable sleeve is connected to hold-down arm 6, described hold-down arm 6 is provided with two rollers 7 of arranging up and down, one end of described retarding spring 3 is fixedly connected on stay bearing plate 1 and the other end is connected to the end of hold-down arm 6, one end of described brake collar 2 is connected on stay bearing plate 1 and the other end is connected to the end of hold-down arm 6, described brake collar 2 is wrapped on brake disc 5, the surface of described rotating shaft 4 is fixedly connected with drum sheath 8, the two ends of described drum sheath 8 are provided with the cover 9 that is locked for blocking described hyaline membrane reel.
In actual applications, first hyaline membrane reel is fixed in rotating shaft 4, and hyaline membrane is wound around successively by two rollers 7, hyaline membrane exports pulling force, at this moment rotating shaft 4 starts to rotate, brake disc 5 is driven to rotate, rotating shaft 4 slowly due to inertia more and more faster, friction force now between brake disc 5 and brake collar 2 is increasing, brake collar 2 pulls hold-down arm 6 to rotate, now retarding spring 3 starts to extend, produce counter pull, restriction brake collar 2 drives hold-down arm 6 to rotate, in the process, hold-down arm 6 is in a relatively stable position, such plastic film also can not be too fast and lax due to blowing.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
Claims (2)
1. a hyaline membrane lays feed mechanism, comprise stay bearing plate, it is characterized in that: also comprise brake collar and retarding spring, described stay bearing plate is provided with for rotating shaft that is fixing and support hyaline membrane reel, in described rotating shaft, fixed cover is connected to brake disc, movable sleeve is connected to hold-down arm, described hold-down arm is provided with two rollers of arranging up and down, one end of described retarding spring is fixedly connected with on the supporting plate and the other end is connected to the end of hold-down arm, one end of described brake collar connects on the supporting plate and the other end is connected to the end of hold-down arm, described brake collar is wound around on the disc brake rotor.
2. hyaline membrane according to claim 1 lays feed mechanism, it is characterized in that: the surface of described rotating shaft is fixedly connected with drum sheath, and the two ends of described drum sheath are provided with and are locked cover for blocking described hyaline membrane reel.
