Further, first support component 31 further includes the first pull rod 315, and one end of first pull rod 315 is solid
It is scheduled in another straight-bar portion of first right angle mandril 312, the other end runs through the second axial trough of the second support bar 321
325, precommpression is carried out for the second spring 323 in the second axial trough 325 to the second support bar 321.That is, institute
It states the first pull rod 315 to stretch out for separating the second slide bar 324 with second spring 323, and second spring 323 is with precompressed
First pull rod 315 is arranged in the mode of contracting, and first right angle mandril 312 is able to drive first pull rod 315
It is detached from the second support bar 321, and after the first pull rod 315 is detached from second support bar 321, the second spring 323 being pre-compressed
The second slide bar 324 can be pressed, to drive the straight-bar portion of the second right angle mandril 322 to stretch to the second groove 12, and with it is second recessed
The slot bottom of slot 12 is contacted.That is, it is straight by the first of the first support component 31 to work as the first groove 11 on cylinder 10
After the top of angle mandril 312 is worn, 322 ability of the second right angle mandril of the second support component 31 cooperates with the slot bottom of the second slot 12.
Second support component 32 further includes the second pull rod 326, and one end of second pull rod 326 is fixed on described
In another straight-bar portion of two right angle mandrils 322, the other end run through the third support rod 331 third axial trough 335, for pair
Third spring 333 in the third axial trough 335 of the third support rod 331 carries out precommpression, and second right angle mandril 322
It is able to drive second pull rod 326 and is detached from the third support rod 331.
The third support component 33 further includes third pull rod 336, and one end of the third pull rod 336 is fixed on described
In another straight-bar portion of three right angle mandrils 332, the other end run through the 4th support rod 341 the 4th axial trough 345, for pair
The 4th spring 343 in 4th axial trough 345 of the 4th support rod 341 carries out precommpression, and third right angle mandril 332
It is able to drive the third pull rod 336 and is detached from the 4th support rod 341.
From the foregoing, it will be observed that the roller 100 of the present embodiment is when in use, driving of the first right angle mandril 312 in the first spring 313
Under press against the slot bottom of the first groove 11, and the second right angle mandril 322 stretch to it is in the second groove 12 and living with the second groove 12
Dynamic cooperation, third right angle mandril 332 stretch in third groove 12 and cooperate with 13 activity of third groove, and mandril 342 stretches to
Cooperate in 4th groove 14 and with 14 activity of the 4th groove.Due to the second right angle mandril 322 and the second groove 12, third right angle top
Activity cooperates respectively for bar 332 and third groove 13, mandril 342 and the 4th groove 14, in this way the roller 100 when in use it is avoided that
Because the through-hole 21 on the end cap 20 that some sundries such as external dust pass through roller 100 enters in cylinder 10 cause second
Right angle mandril 322 and the second groove 12, third right angle mandril 332 and third groove 13, are tied between mandril 342 and the 4th groove 14
Block and solidify, it is ensured that the second support component 32 and the second groove 12, third support component 33 and third groove 13 and the 4th
Support component 34 and the 4th groove 14 can participate in work.And the first pull rod 315 on the first right angle mandril 312, the second right angle
The second pull rod 326 on mandril 322, the Rational structure setting of the third pull rod 336 on third right angle mandril 332, so that first
Support component 31 and the first groove 11, the second support component 32 and the second groove 12, third support component 33 and third groove 13,
And the 4th support component 34 can successively work with the 4th groove 14, with this meet the first groove 11 on the inner face of cylinder 10,
The depth of second groove 12, third groove 13 and the 4th groove 14 gradually becomes shallower as, and the abrasion of roller 100 is by the outer of cylinder 10
What end face was gradually worn inward, that is to say, that the first right angle mandril of the first support component 31 on the roller 100 of the present embodiment
312 first run through the first groove 11 on cylinder 10, and then the second right angle mandril 322 in the second support component 32 runs through cylinder 10
On the second groove 12, then third groove 13 of the third right angle mandril 323 in third support component 33 on the cylinder 10,
Fourth groove 13 of the mandril 342 on cylinder 10 in last 4th support component 34, and the cylinder of the corresponding roller 100
10 surfaces are by different degrees of abrasion.
It is appreciated that the outer end face that 100 upper shell 10 of pair roller barrel is capable of in the part that transmission belt 200 wraps up roller 100 carries out
It squeezes, be capable of the first spring of partial shrinkage 313 of the first right angle mandril 312 of ejection the first groove 11 of stretching and enter to cylinder
In 10 or ejection stretches out the partial shrinkage second spring 323 of the second right angle mandril 322 of the second groove 12 and enters to cylinder
In 10 or ejection stretches out the partial shrinkage third spring 333 of the third right angle mandril 332 of third groove 13 and enters to cylinder
In 10 or ejection is stretched out the 4th spring 343 of partial shrinkage of the mandril 342 of the 4th groove 14 and is entered in cylinder 10;And
Conveyer belt 200 does not wrap up the part of roller 100, and the first right angle mandril 312 will be under the driving of the first spring 313 from cylinder
10 the first groove 11 stretches out or the second right angle mandril 322 will be under the driving of second spring 323 from the second of cylinder 10
Groove 12 stretches out or third right angle mandril 332 will be stretched under the driving of third spring 333 from the third groove 13 of cylinder 10
Out or mandril 342 will stretch out under the driving of the 4th spring 343 from the 4th groove 14 of cylinder 10.And transmission belt 200 is wrapped
When wrapping up in roller 100, the transmission belt 200 of different location is contacted with roller 100 is, the cylinder 10 of 200 pair roller barrel 100 of transmission belt pushes away
Top power is different, and in this way with the rotation of roller 100, the part for stretching out 100 upper shell 10 of roller carries out one to transmission belt 200
A contracting is stretched, such people, can be intuitively from the number of the raised transmission belt 200 of roller 100 when judging the abrasion condition of roller 100
Then amount recycles groove to offer on cylinder 10 to obtain the cylinder 10 that several support components have stretched out the roller 100
Depth and cylinder 10 thickness, to judge thickness that the roller 100 is worn indirectly.
To sum up, roller provided by the present invention, by reasonable structure setting, so that the roller is when in use, Ke Yitong
Crossing support component part and stretching out cylinder and carry out the abrasion condition of intuitive judgment roller surface realizes pair roller barrel compared with prior art
The intuitive judgment of surface abrasion, has been convenient for the judgement of the abrasion condition of pair roller barrel, and the judgement of the abrasion on pair roller barrel surface not shadow
The normal use for ringing roller, the normal use of the transmission device using the roller, and the cylinder table of pair roller barrel are ensured with this
The judgment accuracy of the abrasion condition in face is high.
