Description
Technical field
The utility model belongs to Lacing machine field, relates in particular to a kind of film feeding mechanism.
Background technology
Lacing machine, to use paper tape or PE film bale packing paper products, medicine, cosmetics, electronic product and general light-duty article, then tighten up paper tape or PE film its two ends are bonding by hot melten type, its mainly by sending band, move back band, joint connects shutoff device, driving system, track frame and control setup and formed, its function is paper tape or PE film to be close to be tied parcel post surface, assurance parcel post not because tying up not firm being scattered, makes product bale packing neat appearance in transportation, storage simultaneously.
As shown in Figure 2, the PE film of existing Lacing machine is to be all directly sleeved on the roller c of main shaft a, because roller c is connected with main shaft a by antifriction-bearing box b, in the inner side of roller c, be provided with a shoulder block d, at the external side end of main shaft a, by nut, be provided with one and prevent that roller c and PE film from skidding off the baffle ring e of main shaft a, PE film can drive roller Free-rolling pullling under power effect.Often there is following several shortcoming in above-mentioned this structure: one, because the position of shoulder block and baffle ring is fixed, cannot adjust the axial location of PE film on main shaft, when there is deviation in the power of the pullling center of Work-feeding means and the radial center of PE film, can make the both sides unbalance stress of PE film, under decomposition of force effect, on the PE film of being pullled, can form the oblique trace that draws because of unbalance stress, have a strong impact on the neat appearance of packaged thing.Two, because the distance between shoulder block and baffle ring is fixed substantially, therefore the width that is sandwiched in the PE film between two kinds is also just non-adjustable, as the PE film of need use different size width, needs to change main shaft and the roller of different size, applicability is low, and replacement cost is high, loaded down with trivial details.Three, baffle ring is arranged on the external side end of main shaft by nut, cannot carry out autonomous rotation to it and regulate when roller rotates, and when PE film, is pullling while driving roller Free-rolling under power effect, and inertia when roller tends to because of motion rotates the excessive film feeding causing.
Utility model content
The purpose of this utility model is to provide a kind of and is applicable to different size width PE film, locates adjustable and film feeding mechanism accurately.
This film feeding mechanism that the utility model provides, comprise that level is arranged on the main shaft on column, by two antifriction-bearing boxs, be arranged on the roller on main shaft, this mechanism also comprises inner retaining side, outer rib and roller positioning component, described roller positioning component comprises back-up ring, Compress Spring and adjusting sleeve, described inner retaining side is sleeved on roller medial extremity by an inner retaining side cover, described outer rib is sleeved on roller external side end by an outer rib cover, described inner retaining side cover and outer rib cover are fixed on each end of roller by a positioning screw respectively, described back-up ring can be sleeved in axial sliding on main shaft and with the outside face of roller and join, described adjusting sleeve is socketed on main shaft external side end by transition fit, described Compress Spring is arranged on the main shaft between back-up ring and adjusting sleeve, described adjusting sleeve screws to main shaft inner side by Compress Spring and back-up ring and makes roller axial location exert pressure and prevent that its transition from rotating film feeding to roller on main shaft.
For guaranteeing that the utility model is in motion process, PE film under outside knockout press effect not can with roller generation relative sliding, can not increase the abrasion factor between two contact surfaces, positioning screw and main shaft that described inner retaining side puts are perpendicular, and what the inner of the positioning screw that described outer rib puts tilted towards column is arranged on roller.
Compared with prior art, the utlity model has several under a little:
1, because inside and outside rib cover is to be fixed on roller by positioning screw, when there is relatively large deviation in the power of the pullling center of Work-feeding means and the radial center of PE film, can first adjust the position of inside and outside rib on roller, make PE film radial center and the power of the pullling center superposition of Work-feeding means, by positioning screw, pass again the inside and outside rib cover clamping roller of each side, complete the axial location of inside and outside rib, guarantee that PE film both sides are stressed evenly, can not form the oblique trace that draws, guarantee the neat appearance of packaged thing.
2, because inside and outside rib is enclosed within after can moving on main shaft fixingly again, the distance that can make each rib put between inside and outside rib is adjusted to some extent, thereby applicable to the PE film that different size width is installed, applicability is strong, and cost is low.
3, by the roller positioning component of installing on main shaft external side end, when the stop motion of PE film no longer pulls roller to rotate, not only can utilize the shock damping action of Compress Spring, the excessive film feeding that inertia while preventing roller because of motion causes, can also carry out damping adjusting power by adjusting the elasticity of Compress Spring, applicable under different film feeding speed, the inertia of elimination roller.
4, the utility model fast changeable PE film, when needs change film, only need unscrew the positioning screw on outer rib, takes out outer rib, changes film.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
