Abstract

The utility model relates to a tensioning wheel for a disposable sanitary product belt detaching device. The tensioning wheel comprises a core shaft. A plurality of ball bearings are evenly distributed on the core shaft at intervals, and the position, between every two adjacent ball bearings, on the core shaft is connected with an interval spacer bush in a sleeved mode. The ball bearings are sleeved with a transition rolling sleeve in a connected mode, and the inner rings of the ball bearings are in key connection with the core shaft. The outer rings of the ball bearings are in key connection with the transition rolling sleeve. The two sides of the core shaft are respectively connected with a stop collar in a screwed mode, and the stop collars are used for limiting the positions of the outermost ball bearings. The two stop collars are tightly screwed to tightly combine the ball bearings on the core shaft. The transition rolling sleeve is in rotation connection with the core shaft through the ball bearings, and therefore enough radiating gaps are formed between the transition rolling sleeve and the core shaft. The radiating efficiency of the transition rolling sleeve is improved, and a belt is protected against burnout caused by overheating.

Description

A kind of disposable sanitary articles belt disassembling device Idle wheel

Technical field

The utility model relates to a kind of disposable sanitary articles belt disassembling device Idle wheel.

Background technique

As the patent (patent No.: the fast detachable belt unit of being talked about 200510123184.1) formerly, control the degree of tightness of belt by the adjustable Idle wheel increasing, thereby facilitate the dismounting of belt, but traditional Idle wheel is the solid wheel adopting, non-constant dispels the heat, often there is heating in belt, then emits the phenomenon of smelly cigarette (belt burns) after working on Idle wheel for a long time, have a strong impact on the life-span of belt.

Model utility content

For the problems referred to above, the utility model proposes a kind of disposable sanitary articles belt disassembling device Idle wheel, improve the heat dispersion of Idle wheel, extend the working life of belt in belt disassembling device.

For solving this technical problem, the utility model is taked following scheme: a kind of disposable sanitary articles belt disassembling device Idle wheel, comprise mandrel, on mandrel, there are uniformly at intervals multiple ball bearings, on mandrel between adjacent two ball bearings, be socketed with interval spacer, ball bearing is socketed with transition roll sleeve outward, the inner ring of ball bearing forms key with mandrel and is connected, between the outer ring of ball bearing and transition roll sleeve, forming key is connected, the both sides of mandrel are connected with respectively the stop collar for limiting most external ball bearing position, two stop collars screw by each ball bearing and tightly on mandrel.

Further, interval spacer is connected with mandrel formation key.

Further, the outer ring of outermost two ball bearings is connected with respectively the side bumper circle for limiting the displacement of transition roll sleeve.

By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: transition roll sleeve is rotationally connected through multiple ball bearings and mandrel formation, thereby make to form between transition roll sleeve and mandrel abundant heat radiation gap, thereby improve the radiating efficiency to transition roll sleeve, avoid that belt is overheated to be burnt out.

Idle wheel is in the time of work, belt is across having mercy on transition roll sleeve, belt moves and drives transition roll sleeve to rotate, the heat that the work of transition roll sleeve produces all leaves between the outer ring of ball bearing and inner ring, stop collar, interval spacer and side bumper circle have effectively limited the position of ball bearing on mandrel, thereby it is more stable, reliable that whole Idle wheel is worked together.

Transition roll sleeve drives the outer ring rotating of ball bearing, thereby drives each ball to rotate, and produces wind thereby make to form air-flow between transition roll sleeve and mandrel, accelerates heat radiation.

Wherein, 1, mandrel, 2, ball bearing, 3, transition roll sleeve, 4, interval spacer, 5, stop collar, 6, side bumper circle, 11, driving pulley, 12, driven pulley.

Embodiment

Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.

With reference to figure 1 Fig. 2 the present embodiment, a kind of disposable sanitary articles belt disassembling device Idle wheel is disclosed, comprise mandrel 1, on mandrel 1, there are uniformly at intervals multiple ball bearings 2, on mandrel 1 between adjacent two ball bearings 2, be socketed with interval spacer 4, each interval spacer 4 is equal in length, can effectively control the distance between each ball bearing 2 by the length of controlling each interval spacer 4, the outer transition roll sleeve 3 that is socketed with of ball bearing 2, the inner ring of ball bearing 2 forms key with mandrel 1 and is connected, between the outer ring of ball bearing 2 and transition roll sleeve 3, forming key is connected, the both sides of mandrel 1 are connected with respectively the stop collar 5 for limiting most external ball bearing 2 positions, two stop collars 5 screw by each ball bearing 2 and tightly on mandrel 1.Stop collar 5 is with mandrel 1 for being threaded, and interval spacer 4 forms key with mandrel 1 and is connected.The outer ring of outermost two ball bearings 2 is connected with respectively the side bumper circle 6 for limiting 3 displacements of transition roll sleeve.

Transition roll sleeve 3 forms and is rotationally connected with mandrel 1 through multiple ball bearings 2, thereby makes to form between transition roll sleeve 3 and mandrel 1 abundant heat radiation gap, thereby the radiating efficiency of raising to transition roll sleeve 3 avoids that belt is overheated to be burnt out.

Idle wheel is in the time of work, belt is across having mercy on transition roll sleeve 3, belt moves and drives transition roll sleeve 3 to rotate, transition roll sleeve 3 the produced heat of working all leaves between the outer ring of ball bearing 2 and inner ring, stop collar 5, interval spacer 4 and side bumper circle 6 have effectively limited the position of ball bearing 2 on mandrel 1, thereby it is more stable, reliable that whole Idle wheel is worked together.

Transition roll sleeve 3 drives the outer ring rotating of ball bearing 2, thereby drives each ball to rotate, and produces wind thereby make to form air-flow between transition roll sleeve 3 and mandrel 1, accelerates heat radiation.

As shown in Figure 3, Idle wheel is arranged on the structural representation on belt disassembling device, belt is rotating on belt wheel 11, driven pulley 12 and Idle wheel across having mercy on, Idle wheel has the mechanism of adjustable swing at device, this mechanism is in (the patent No.: existing introduction 200510123184.1), is not described in detail at this of patent formerly.Improved the heat dispersion of Idle wheel, can effectively avoid belt for a long time transport heat burn out, extend the life-span when belt, extended the working life of whole device.

Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
