Technical field
The present invention relates to a kind of frame structure for combing machine.
Background technology
Typical combing machine has the operation part being furnished with eight combing heads.Each combing head comprises nipper and combing cylinder.Nipper keeps each with the end of the lap of scheduled volume feeding.The end of lap is by combing cylinder combing.Lap is changed into knitting wool (fleece) by this.Along with nipper advances, knitting wool moves towards detaching roller.Detaching roller is in response to before knitting wool and then along counter-rotating, and the knitting wool obtained before (at first knitting wool) is return.Then, the front inlet side of the tail end of online knitting wool and the knitting wool (follow-up knitting wool) of new combing is overlapping.Subsequently, detaching roller rotates with forward direction, thus obtains knitting wool from nipper, and the tail end of knitting wool is by top comb combing, and it thrusts in knitting wool.Afterwards, the knitting wool repeated in combing head manufactured by this process is bunched to bundle and is drawn out of, and is extruded by pressure roller afterwards thus become sliver.
Modern combing machine works in the mode of the rotary speed of combing cylinder for about 200 to 300rpm.Correspondingly, nipper advance and return and the oscillating motion (front and back pivotable) of detaching roller with fast to 200 to 300 beats/min of execution.The quality of the knitting wool obtained is subject to the combing cylinder when lap is combed cylinder combing and enters the impact of the penetration amount of the pin of lap.Particularly, when the degree of depth of penetration amount changes about 0.3mm(penetration depth) time, the quality of the sliver of acquisition changes.Therefore, all combing heads are at tongs plate axis, must have identical position relationship between combing cylinder and detaching roller.
As shown in fig. 3, typically, the frame structure for combing machine comprises machine frame (central frame) separated from one another for combing head 50 (sequence number is that the day disclosure utility model of 6-12483 is announced).According to this publication, the frame structure for combing machine comprises multiple base table panel 51 and is arranged on eight central frames 52 that base table panel 51 vertically extends.As shown in Figure 3 B, tongs plate axis 53, cylinder axis 54, detaching roller 55 and lap roller 56 is rotatably supported by central frame 52 by the bearing do not depicted, and extends through central frame 52 simultaneously.In figure 3 a, tongs plate axis 53, cylinder axis 54 and detaching roller 55 is eliminated.
Traditionally, frame structure is designed so that the distance between base table panel 51 with each in tongs plate axis 53, cylinder axis 54 and the detaching roller 55 in the part corresponding with each combing head 50 is equal for all combing heads 50.This needs base table panel 51 and central frame 52 by highly precisely machined.In addition, high assembly precision is needed.Such as, the PT positional tolerance for the hole of receiving tongs plate axis 53 and other axle needs to be 0.01 millimeter or less.In order to meet this requirement, need to perform constant temperature machine processing.This causes a large amount of manufacturing steps and increases cost.
