Description

A kind of bearing block

Technical field

The utility model is related to technical field of mechanical transmission, more particularly to a kind of bearing block.

Background technology

Paper collecting machine is often completed after a roll paper, it is necessary to spool with winding motor main shaft is separated and is removed from bearing block, New spool is re-replaced again to be placed on bearing block, is then connected by shaft coupling with winding motor main shaft.So repeatedly Spool is replaced, needs to dismantle screw or by bearing block from axial pull-out every time, operating difficulties is time-consuming and laborious, both increases Labor strength, and cause the work efficiency of toilet paper low.

As it can be seen that the prior art could be improved and improve.

Utility model content

Part in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide bearing blocks, it is intended to solve existing The technical issues of spool for having paper collecting machine in technology dismantles difficulty from bearing block.

In order to achieve the above object, the utility model takes following technical scheme：

A kind of bearing block, including bottom plate and the undersetting being oppositely disposed on bottom plate；It respectively can on each undersetting Releasably there are one upper brackets for connection；It is rotatably coupled between two undersettings there are two roller, it can between two upper brackets Rotationally roller there are one connection, three rollers to be horizontally disposed with；There are one upper bracket and undersetting per one side relatively open up Notch can wear the notch completely with the tangent cylinder of the lateral wall of three rollers.

In the bearing block, one end of each upper bracket is hinged respectively with that corresponding undersetting, two upper brackets Other end connection there are one locking device, which snaps connection with two undersettings.

In the bearing block, the locking device includes the shaft hinged with two upper brackets, is arranged in shaft Hook and the hook bar being arranged on two undersettings；There are one being opened up at the corresponding hook bar of hook bar is linked up with for clamping Card slot.

In the bearing block, there are one handles for connection on hook.

In the bearing block, one is provided on two upper brackets for carrying out the /V of /V to hook slewing area Bar.

In the bearing block, each roller includes a mandrel and the bearing being set on mandrel respectively.

In the bearing block, the both sides of each bearing are respectively arranged with a baffle ring.

Connecting hole there are four being opened up in the bearing block, on bottom plate.

Advantageous effect：

The utility model provides a kind of bearing block, flatly sets two rollers on undersetting, horizontal on upper bracket Ground sets two rollers, is supported so as to fulfill the spool to paper collecting machine；Since upper and lower bearing is detachably connected, replace Upper bracket need to only be dismantled and spool can be taken out upwards during spool, avoided and axially take out spool as prior art, It is time saving and energy saving to realize, puies forward efficient purpose.

Specific embodiment

The utility model provides a kind of bearing block, for make the purpose of this utility model, technical solution and effect it is clearer, Clearly, the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should be appreciated that tool described herein Body embodiment only to explain the utility model, is not used to limit the utility model.

It please refers to Fig.1 to Fig.3, the utility model provides a kind of bearing block.For the ease of understanding the utility model, Fig. 4 shows It has anticipated out a kind of paper collecting machine, wherein applying bearing block provided by the utility model.

The bearing block includes bottom plate 51 and the undersetting 521 being oppositely disposed on bottom plate；On each undersetting A upper bracket 522 is detachably connected with respectively；It is rotatably coupled between two undersettings there are two roller 53, on two It is rotatably coupled between bearing there are one roller 53, three rollers are horizontally disposed with；Upper bracket and undersetting per one side is opposite Ground is opened up there are one notch 50, and the notch can be worn completely with the tangent cylinder of the lateral wall of three rollers.It should be noted that Cylinder described herein is imaginary, is not some specific component in the bearing block.Referring to Fig. 4, it ought actually answer When using in paper collecting machine, this means, the both ends of the spool 3 of paper collecting machine are outer with three rollers 53 of that corresponding bearing block 5 respectively Side wall is tangent.Wherein, one end of spool 3（It is illustrated as left end）Stretched out from the notch of corresponding bearing block and with winding motor 1 Main shaft is connected by shaft coupling 2.During work, winding motor driving spool rotates, and three rollers on each bearing block are also therewith It rotates, realizes each roller and rolling friction occurs so as to play supporting role with spool.And complete the winding work of a roll paper Afterwards, it is only necessary to upper bracket and undersetting are unclamped, the connection of electric machine main shaft and spool is unclamped, spool can be taken out upwards, it is time saving It is laborsaving.After a upper spool is rechanged, upper bracket and undersetting are locked.

Further, one end of each upper bracket（Fig. 1 show right end）It is hinged respectively with that corresponding undersetting, two There are one locking device, which snaps connection with two undersettings for the other end connection of a upper bracket.

Further, the locking device includes the shaft 541 hinged with two upper brackets, the hook being arranged in shaft 542 and the hook bar 543 that is arranged on two undersettings；It is linked up with there are one being opened up at the corresponding hook bar of hook for clamping The card slot 5421 of bar.During operation, rotational hook is only needed, you can realize the locking and release of upper and lower bearing, it is convenient and efficient.

In order to facilitate the operation, there are one handles 544 for connection on hook.By holding handle, you can easily rotational hook. Preferably, it is to be threadedly coupled between handle and hook.

Further, one is provided on two upper brackets for carrying out the gag lever post 545 of /V to hook slewing area. By setting gag lever post, prevent from breaking hook bar due to excessively rotational hook.

There are many forms of roller, a kind of setting of relatively simple practicality provided herein：Each roller 53 includes one respectively Root mandrel 531 and the bearing 532 being set on mandrel.That is, each mandrel is used to be fixed on corresponding upper bracket or lower branch On seat, and the outer ring of each bearing is realized and is rotated, so as to be supported to the spool 3 of paper collecting machine and rolling friction occurs.

Further, the both sides of each bearing are respectively arranged with a baffle ring 55.By setting baffle ring, can prevent each The side wall during outer ring rotating of bearing with upper bracket or undersetting interferes.

Further, connecting hole 511 there are four being opened up on bottom plate.By setting connecting hole, bolt and collection are facilitated insertion into The pedestal of machine is attached.

For the ease of making, two undersetting specifications are identical, and two upper bracket specifications are also identical, and above-mentioned 3 rollers are adopted With identical mandrel and roller.

For the ease of installation and more stably supporting shaft, two rollers height on undersetting is identical, and vertical three In the projection of the plane of a roller（As shown in Figure 1）, the central point line composition isosceles triangle of three rollers.

It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model Scope of the claims.
