Abstract
The invention discloses a bearing structure convenient for disassembling a mandrel. The bearing is divided into two sections, and both the sections are provided with two positioning pieces, wherein one bearing section is provided with a transmission wheel. The bearing structure is characterized in that two wheel-shaped protrusions are formed on the middle parts of the two positioning pieces of the other bearing section, and a wrench sleeve is sleeved on the periphery of the two wheel-shaped protrusions; the wrench sleeve is provided with a wrench and a positioning screw, and the positioning screw passes through the wrench sleeve and goes deep into a groove formed by the two wheel-shaped protrusions; and a spring is arranged between the wheel-shaped protrusions and the positioning piece on the tail part of the bearing. The bearing structure has simple structure and convenient operation, realizes the disassembly and the assembly of the bearing through pulling the wrench, is convenient to maintain, greatly improves the working efficiency and saves the labor force.
Description
Technical field
The present invention relates to the bearing structure used on a kind of wrap-up, especially relate to a kind of bearing structure of being convenient to bearing dismantling, belong to field of mechanical technique.
Background technique
We know, when the rolling work of plastic bag etc. being put in order volume, can use the mandrel that is used for rolling, and the bearing that drives the mandrel rotation, usually, bearing is divided into two sections, is separately positioned on the two ends of mandrel, dock with mandrel, and traditional bearing all is to be positioned on the support by locating piece etc., has driven rotation by the drive wheel that is fixed on the one end then, rotates thereby drive mandrel, plastic bag etc. is carried out rolling, the Bearing Installation dismounting mandrel of this kind mode bothers very much, especially when mandrel produces fault, keeps in repair very inconvenient, have a strong impact on manufacturing efficiency, increased labour cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the objective of the invention is to simple in structure, cost is low, the bearing dismantling structure of easy accessibility.
The present invention is achieved through the following technical solutions:
A kind of bearing structure of convenient for disassembling mandrel, described bearing is divided into two sections, all be provided with two locating pieces on each section, wherein one section bearing is provided with drive wheel, it is characterized in that, the position of other one section bearing in the middle of two locating pieces forms two colyliform projectioies, periphery two colyliform projectioies also is with a spanner cover, the spanner cover is provided with spanner and set screw, set screw passes the spanner cover and extend in the groove that two colyliforms convex to form, and also is provided with spring between the locating piece of colyliform projection and bearing afterbody.
The invention has the beneficial effects as follows: the present invention is simple in structure, and is easy to operate, realizes the dismounting of bearing by pulling spanner, easy to maintenance, improved working efficiency greatly, saved the labour.
Description of drawings
Fig. 1 is the plan view of one embodiment of the invention;
Fig. 2 is the plan view of one embodiment of the invention;
Fig. 3 is the sectional view of one section bearing of the present invention.
Main reference character implication is among the figure:
1, bearing 2, mandrel 3, locating piece 4, drive wheel 5, colyliform projection 6, spanner cover 7, spanner 8, positioning screwn 9, spring
Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the plan view of one embodiment of the invention; Fig. 2 is the plan view of one embodiment of the invention; Fig. 3 is the sectional view of one section bearing of the present invention.
As shown in Figure 1 to Figure 3: the bearing structure of convenient for disassembling mandrel, described bearing 1 is divided into two sections, all be provided with two locating pieces 3 on each section, wherein one section bearing is provided with drive wheel 4, the position of other one section bearing in the middle of two locating pieces 3 forms two colyliform projectioies 5, periphery two colyliform projectioies 5 also is with spanner cover 6, spanner cover 6 is provided with spanner 7 and set screw 8, set screw 8 passes spanner cover 6 and extend in the groove of protruding 5 formation of two colyliforms, and also is provided with spring 9 between the locating piece 3 of colyliform projection 5 and bearing 1 afterbody.
When work, drive wheel 1 drives bearing 1 and rotates, and mandrel 2 is fixed on the centre of two sections bearings 1 by two sections bearings 1, and rotate with bearing 1, when the mandrel 2 in the middle of needs will be positioned at two sections bearings 1 is unloaded down, only need outwards to pull vertically spanner 7, at this moment, because positioning screwn 8 extend in the groove of two colyliform projectioies 5, under the active force of positioning screwn 8, bearing is outwards motion simultaneously, and pressure spring 9, but the dismounting of mandrel 2 is realized on ground, aspect this moment, and the present invention has improved working efficiency greatly, has saved the labour.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
