Description

A kind of roller bed device

Technical field

The utility model is related to device for transporting objects, particularly a kind of roller bed device for conveying glass.

Background technology

When producing glass, glass is generally conveyed with roller-way, and roller-way includes rotatable roller, and roller includes mandrel With the roller being arranged in the middle part of mandrel.Rubber rollers are a kind of conventional roller, and the outer layer of roller is smooth rubber layer, rubber Roller entirety contact surface is big, if roller faces be stained with glass dregs or other dirty when it is easy to there are glass scratch, dirty feelings Condition.These problems existing for rubber rollers, have uses concavo-convex rubber rollers instead, but effect improved inconspicuous；Have uses aramid fiber Rope is wound around rubber rollers, and scratch and dirty bad ratio are obviously improved, but there is potential safety hazard, and usage cycles are short simultaneously, 3 The moon need to be changed once.

Additionally, the two ends of roller are generally arranged on base by bearing, base is provided with semi-circular recesses, and bearing is placed On groove, compress semicircular bearing card above bearing, by screw, bearing card is arranged on base, roll end is pacified It is contained on the inner ring of bearing.This structure is very inconvenient to roller maintenance, and maintenance every time is required for two people's cooperations, needs first to tear open Lower screw is taken down bearing card and could be taken out roller, and the take-down time is long, and maintenance efficiency is low.Especially for annealing furnace air grid section roller The installation of road medial end, because of annealing furnace air grid section limited inside space, human users are inconvenient, and screw did not moved, very for a long time Difficulty turns, and dismantling and installing all wastes time and energy, difficult in maintenance.

Content of the invention

In order to solve glass scratch, the fouling problems that current rubber rollers exist, the utility model proposes a kind of roller-way Device, to reduce the scratch to glass, soiled condition, and improves safety in utilization and service life.

To achieve these goals, the utility model provides a kind of roller bed device, including roller, roller include roller and It is arranged on the mandrel of roller end, the outer layer of roller is rubber layer it is characterised in that being cased with multiple O shapes in described rubber layer Snare, described snare using PU material, there is elasticity vertical with the axis of roller, along adjacent two of roller axis direction The distance between described snare is equal.

The roller bed device that the utility model provides, only has snare and glass contact during conveying glass, contact area is little, glass Glass dregs after breakage and dirty be difficult to stick, PU material is wear-resisting, has certain toughness simultaneously, glass dregs etc. are very difficult prick into, Substantially reduce glass scratch and dirty, glass occur scratch and dirty after easily search problem places, snare is installed and replacing All very convenient, using safety and life-span length.

Specific embodiment

Referring to Fig. 1 and Fig. 2, roller bed device includes roller, and roller includes roller 12 and is arranged on 12 two ends of roller Two mandrels 11, roller 12 is solid cylinder, and its outer layer is rubber layer 14, and the material of rubber layer 14 can be rubber or silicon Glue.Rubber layer 14 is provided with multiple annular grooves being inwardly recessed, and multiple annular grooves are uniform along the axis direction of roller 12 Arrangement, each annular groove is vertical with the axis of roller 12, along between the two neighboring annular groove of roller axis direction away from From equal.The snare 13 of one O shape is cased with each annular groove, annular groove is filled up by snare 13, and straight in roller It is taken in and 13 exceeds rubber layer 14 in footpath direction.Snare 13 using PU material and has elasticity.Snare 13 is vertical with the axis of roller, Equal along the distance between the two neighboring snare of roller axis direction 13.During conveying glass, only snare 13 and glass contact, Contact area is little, the glass dregs after glass breakage and dirty be difficult to stick, PU material is wear-resisting, has certain toughness, glass simultaneously Glass slag etc. is very difficult prick into, substantially reduce glass scratch and dirty, glass occur scratch and dirty after easily search problem place, Snare is installed and is changed all very convenient, using safety and life-span length.

Referring to Fig. 3, Fig. 4 and Fig. 5, roller bed device also includes base 2, gland 3, latch 4 and bearing 5, and base 2 is provided with half Round bearing mounting groove, bearing 5 is placed in bearing mounting groove, and one end of mandrel 11 is arranged on bearing inner race.Gland 3 is arranged Above base 2, it is arranged on base 2 by screw, there is between gland 3 and bearing 5 segment distance, bearing 5 is in gland 3 And base 2 between.Gland 3 is provided with two circular grooves 31, and groove 31 is along axis direction (Fig. 4 and Fig. 5 institute of bearing 5 The left and right directions showing) extend, above bearing 5, two grooves 31 are arranged in the left and right sides of bearing 5 axis to groove 31, close Axisymmetrical in bearing 5.Two latches 4 are arranged between gland 3 and bearing 5, and latch 4 is divided into cylindricality along its length direction Portion 41 and tapered portion 42, cylindrical portion 41 global shape is cylinder, and tapered portion 42 global shape is cone, the cone of tapered portion 42 Bottom is connected with cylindrical portion 41 one end, and the maximum gauge of tapered portion 42 is equal to the diameter of cylindrical portion 41, less than the diameter of cylindrical portion 41 Can also.Latch 4 is inserted between the groove 31 of gland 3 and the outer ring of bearing 5, and latch 4 can be inserted along groove in groove 31 Enter or pull out.When the cylindrical portion 41 of latch 4 is inserted into the surface of bearing 5, its state as shown in figure 4, cylindrical portion 41 simultaneously Extruded by gland 3 and bearing 5, bearing 5 is firmly installed on base 2.The shape of groove 31 and the cylindrical portion 41 of latch 4 Profile is adapted, and when groove 31 is pressed in cylindrical portion 41, groove 31 and cylindrical portion 41 paste jail, and groove 31 is easier latch is applied Pressure, and position-limiting action is played to latch.When dismantling bearing when needing repairing, latch 4 is pulled out outward from groove 31, works as cylindrical portion 41 when leaving groove 31 completely, its state as shown in figure 5, now bearing 5 be no longer influenced by the extruding of latch 4, released, directly may be used So that bearing 5 and roller are taken out.

Referring to Fig. 4 and Fig. 5, gland 3 is provided with the elongated seam 32 running through gland, and elongated seam 32 is at the rear one of groove 31 Side.Correspondingly, latch 4 is provided with handle 43 on the face of cylinder of cylindrical portion 41, and handle 43 passes through elongated seam 32 and reaches gland 3 Outside, it is hemispherical that handle 43 stretches out part outside gland, and hemispheric diameter is wider than the width of elongated seam 32, hand Handle 43 will not drop out from elongated seam 32.By holding handle 43, the propulsion to latch 4 and pull-out, hand can be easily carried out Handle 43 has position-limiting action to latch 4 simultaneously, even if latch 4 is completely pulled out of groove 31, also will not drop out from gland 3, It is easy to the installation and removal to bearing, improve maintenance efficiency.

Roll end mounting structure carrys out fixing bearing using two latches, when needing dismounting, latch is pulled out, it is to avoid insert The cylindrical portion of pin is pressed on bearing outer ring, and bearing is released, you can bearing and roller are taken out.After maintenance is good, need to install During bearing, bearing is placed in the bearing mounting groove of base, latch is pushed away toward in the groove of gland, make the cylindrical portion of latch complete Contact with groove and bearing outer ring, bearing is fastened solid.Installing/dismounting is all very convenient, and a people can complete, and improves equipment dimension Shield efficiency, is particularly suitable for limited space, the occasion of human users' inconvenience, such as annealing furnace air grid section roller-way medial end peace Dress.
