Abstract
The utility model provides a four-contact roller two-face double-displacement belt shifter. The utility model is composed of a shifting yoke frame, a connecting rod, a shaft sleeve, a rocker, an adjustable joint and four rollers. The utility model is suitable for a speed shifting mechanism and similar mechanisms in an automatic evener. When the speed of the speed shifting mechanism needs to be changed, the four-contact roller two-face double-displacement belt shifter quickly shifts the belt to move, and then the speed shifting mechanism generates the corresponding speed.
Description
The utility model belongs to the irregular evereven regulated of mechanical delay device by the feeding raw material.
Hair CO7 type evereven is disclosed in high weaving universities and colleges' teaching materials " wool spinning " (textile industry publishing house in October, 1980 version).Its shipper pole mechanism is made up of pressing fork rack and the roller that is contained in the pressing fork rack head end, links to each other with other parts by control joint.When input connecting rod input speed change signal, shipper pole mechanism is that the roller belt shifter is just stirred the belt displacement, realizes speed change.But existing roller belt shifter is a twin roller type, is contained in the pilled-in selvedge of driving belt, and moving resistance is bigger, and the belt wearing and tearing are corresponding also big, can not in time change the rotating speed of passive cone drums, and hysteresis is arranged, and response characteristic is relatively poor, has influenced the neat and well spaced quality of shaping.Simultaneously, because main, passive cone drums is a pair of conical belt wheel, the characteristic that the on-stream oriented larger diameter end of driving belt is climbed, therefore belt departs from plumbness all the time in transmission, can not keep vertical with the axis of cone drums, influence the correctness of passive cone drums speed change, also influenced the neat and well spaced quality of shaping.
The purpose of this utility model provides the two-sided dibit shipper pole of a kind of four rollers mechanism, with sensitivity and the correctness that improves passive cone drums speed change.
The purpose of this utility model can reach by following measure: promptly on the both sides of driving belt respectively by adorning a pair roller shift fork, and mutual interlock, but be not in same plane, rely on an end of belt trend cone drums separately, thereby realized the purpose of this utility model.
Accompanying drawing is a structural representation of the present utility model.
Imaginary line partly is aid illustration other parts of the present utility model.
1 is passive cone drums among the figure, and 2 is upper roller, and 3 is pressing fork rack, and 4 is bottom roller, and 5 is the active cone drums, and 6 are the input connecting rod, and 7 is control joint, and 8 is rocking bar, and 9 is fulcrum, and 10,11 is axle sleeve, and 12 is master connecting-rod, and 13 is auxilliary connecting rod, and 14 is driving belt.
Provide an embodiment of the present utility model in conjunction with the accompanying drawings.
On four terminations of pressing fork rack 3 roller that can rotate flexibly 2 or 4 are housed respectively, have formed two pairs of two roller shift forks.The two pairs of two roller shift forks are pitched pilled-in selvedge and the slack list at driving belt 14 respectively, and stagger mutually, are not in same plane, respectively rely on an end of the nearly cone drums of belt.Main, passive cone drums 1,5 is all tapered.The middle part of pressing fork rack 3 has two installation axle hole, is contained in respectively on the end axis of connecting rod 12,13, and can rotates (pressing fork rack 3 actual be a connecting rod).The other end of connecting rod 12,13 is affixed with axle sleeve 10,11 respectively.3,9,10,11,12,13 and frame form a parallel-crank mechanism.The other end of axle sleeve 10 and rocking bar 8 are affixed, and 8 link to each other with control joint 7, and its method of attachment also is fixedly connected, and 6 on input connecting rod is hinged with being connected to of control joint 7.When conduction mechanism input speed change signal, 6 on connecting rod of input affects the two-sided dibit shipper pole of four rollers mechanism to swing back and forth along the cone drums axis, is stirring driving belt 14 and constantly is being shifted, and makes passive cone drums obtain corresponding speed.
The characteristics of four contact roller two-face double-displacement belt shifters are at the slack list of driving belt and pilled-in selvedge while shipper pole, have improved sensitivity and the response characteristic of shipper pole; Simultaneously, two pairs of two roller shift forks respectively rely on an end of the nearly cone drums of belt, can effectively reduce the trend that belt is climbed to the big end of cone drums, have guaranteed that driving belt can be in the position vertical with the cone drums axis all the time, thereby improved the accuracy of speed, guaranteed the shaping quality of sliver. And because the roller number of shipper pole has increased by one times than originally, so the resistance during every pair roller shipper pole has just reduced approximately half, belt weares and teares just little, the service life of having improved belt. Therefore, the utility model has the advantages that the response characteristic that belt moves is good, the tendency that departs from ideal position is little, passive cone drums speed change highly sensitive, and accuracy is good, and the wearing and tearing of belt are little, long service life, thus can effectively control the neat and well spaced rate of shaping.
Claims (3)
1, a kind of roller shipper pole mechanism, form by pressing fork rack, connecting rod, axle sleeve, rocking bar, control joint and roller, it is characterised in that the two ends of pressing fork rack respectively are equipped with a pair roller, and pitch pilled-in selvedge and slack list respectively at driving belt, with the moved further driving belt, formed the two-sided dibit shipper pole of four rollers mechanism.
2, shipper pole according to claim 1 mechanism, it is characterized in that two pair rollers respectively oppositely fork be not in same plane, and rely on an end of the nearly cone drums of belt separately in the pilled-in selvedge and the slack list of belt.
3, shipper pole according to claim 1 mechanism is characterized in that pressing fork rack and connecting rod flexibly connect, and two pairs of two roller shift forks are stirred the driving belt displacement synchronously linearly.
