Abstract
An auto-leveler of a gill box is provided featuring that under the back rollers of the gill box are provided a pair of auxiliary rollers. The auxiliary rollers are fed with uniform tops. The gram weight of the tops fed to the auxiliary rollers is only one fifth of that of tops fed to the back rollers. The front rollers, a needle box and the back rollers move at steady speed. The feeding speed of the auxiliary rollers varies to the non-uniform distribution of the tops detected by the back rollers. When the tops are thicker than those of standard value, the feeding speed of the auxiliary rollers slows down, and vice versa. In this way, the total number of the tops fed to the back rollers and the auxiliary rollers stay unchanged. Detection and leveling are simultaneously carried out without delay, therefore, achieving a uniform leveling effect.
Description
Technical field
The present invention relates to wool spinning technical field, be related specifically to a kind of evereven of gill box.
Background technology
In wool spinning bar process, because the hair precision of evenly feeding of combing machine for fur itself limit, there is great irregularity in made wool top, for improving the irregularity of wool top, can carry out autoleveller to wool top in the grilling operation in rear road.Conventional method carries out autoleveller to wool top on B423 gill box, first by testing agency, feeding wool top is detected, owing to having a segment distance from test point to neat and well spaced point, B423 gill box have employed delay device, namely cylinder is remembered, when making test point arrive at neat and well spaced, just cone drums is made to change the speed of feeding wool top, to reach neat and well spaced object by the signal detected.
The shortcoming of this conventional method is: owing to having a segment distance from test point to neat and well spaced point, B423 gill box have employed delay device, and this delay device is not only complicated, and precision is not high because having certain distance between two steel riders in memory cylinder.Hold the debugging of delay device is also extremely difficult, incorrect owing to debugging, add the irregularity of wool top on the contrary, to such an extent as to part factory simply abandons and need not.At present, some factory also did to improve to autoleveller, allowed rear roller speed remain a constant speed, and regulated front roller speed, equally also had delay, namely will wait until that test point just regulates front roller speed when arriving at neat and well spaced.As long as there is delay, then debugging just postpones very difficulty.
Summary of the invention
The object of the invention is to: overcome the deficiencies in the prior art, a kind of evereven not having to postpone is provided.
For achieving the above object, the technical solution used in the present invention is: below gill box rear roller, increase by a pair auxiliary roller again, auxiliary roller feeds uniform wool top, this wool top grammes per square metre only has rear roller to feed about 1/5th of wool top, front roller, needlecase, rear roller three speed all remain unchanged, and the wool top that auxiliary roller feeding speed detects with rear roller is irregular and change.When wool top is thicker than standard value, then auxiliary roller feeding speed reduces, otherwise when wool top is thinner than standard value, then auxiliary roller feeding speed increases, and to ensure that the summation that rear roller and auxiliary roller feed wool top remains unchanged, thus reaches neat and well spaced object.
Due to the application of technique scheme, the present invention compared with prior art tool has the following advantages: 1, in the present invention, and test point and neat and well spaced point are in same vertical cross-section, detect irregular while neat and well spacedly to adjust at once, do not postpone.2, in the present invention, front roller, needlecase, rear roller three speed all remain unchanged, the impact produced because of inertia when avoiding speed governing.3, the present invention is provided with auxiliary roller, very light in weight, and inertia is little, impacts very little during speed governing.
Accompanying drawing explanation
Fig. 1 is the evereven schematic diagram of gill box of the present invention.
Wherein: 1, front roller; 2, needlecase; 3, rear roller; 4, auxiliary roller; 5, main wool top; 6, auxiliary wool top.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
As shown in Figure 1, the present invention adds a pair auxiliary roller 4 below gill box rear roller 3.Rear roller 3 also plays detection effect.Auxiliary roller 4 and rear roller 3 are in same vertical cross-section.
Main wool top 5 feeds through rear roller 3, and auxiliary wool top 6 feeds through auxiliary roller 4.
When rear roller 3 detects that main wool top 5 is larger than standard value, this signal is converted to analog input programmable controller (PLC), the amplitude that auxiliary roller 4 speed should be reduced is judged by PLC, PLC controls the AC servo motor driving auxiliary roller 4, slow down auxiliary roller 4, remains unchanged with the summation making rear roller 3 and auxiliary roller 4 feed wool top.Detect and carry out with during speed-changing same, do not postpone.
When rear roller 3 detects that main wool top 5 is less than standard value, convert this signal to analog input PLC, the amplitude that auxiliary roller 4 speed should be improved is judged by PLC, PLC controls the AC servo motor driving auxiliary roller 4, accelerate auxiliary roller 4, remain unchanged with the summation making rear roller 3 and auxiliary roller 4 feed wool top.Detect and carry out with during speed-changing same, do not postpone.
Wool top uniformity made by the present embodiment is good.
Claims (4)
1. the evereven of a gill box, specific features is: below gill box rear roller, increase by a pair auxiliary roller again, auxiliary roller feeds uniform wool top, this wool top grammes per square metre only has rear roller to feed about 1/5th of wool top, front roller, needlecase, rear roller three speed all remain unchanged, the wool top that auxiliary roller feeding speed detects with rear roller is irregular and change, and to ensure that the summation that rear roller and auxiliary roller feed wool top remains unchanged, thus reaches neat and well spaced object.
2. the method according to claims 1, is characterized in that: add a pair auxiliary roller below described gill box rear roller.
3. the method according to claims 1, is characterized in that: described front roller, needlecase, rear roller three speed all remain unchanged.
4. the method according to claims 1, is characterized in that: described detection and neat and well spacedly to carry out at one time, does not postpone.
