A lower nipper plate is fixed in front of the lower nipper seat, a trapezoidal groove is formed in the middle of the top surface of the lower nipper plate, a cotton guide plate is arranged in the trapezoidal groove, the cotton guide plate is arc-shaped on the front portion and horizontal at the tail, the tail portion of the cotton guide plate is fixed on the lower nipper plate, a feed roller is arranged above the cotton guide plate, and grooves for holding the feed roller are arranged at two ends of the lower nipper seat; the front end of the bottom surface of the lower nipper plate is provided with a plane, the rear of the plane is gradually raised through circular arc transition, and the lower nipper seat is connected with an upper nipper plate connector in a hinge joint manner. By the arrangement, a cotton feed channel can be flexibly adjusted according to thickness of a small roll, distance of the center of the front end of each nipper plate, the center of each groove and hinge point of each nipper plate can be reasonably arranged, and large quantitative of small rolls and long fibers 35mm above in length are assured to be processed smoothly through a combing machine; due to the arc-raised surface, collision against the lower nipper plate by cylinder needle teeth is avoided, compressive strength of the nipper lip of the lower nipper plate is guaranteed, the nipper plates and a cylinder of the combing machine are prevented from being damaged, and production cost is obviously reduced.
Description
Technical field
The present invention relates to the technical field of cotton spinning equipment special-purpose member, be specifically related to a kind of modern comber nipper mechanism.
Background technology
The Main Function of nipper mechanism of combing machine is that pincers are held cotton clump and managed for cylinder pin stripping fork, and must be sent to combing separate jaw by clump, completes Detaching and Lapping work.The design of nipper to meet claimed below:
1, ensure that different-thickness cotton layer is to cotton smooth；Cotton passage of giving between nipper plate and feed roll motor decides the cotton layer thickness (rouleau is quantitative) of combing machine processing rouleau；Giving cotton passage the narrowest, the rouleau being suitable for is the least, gives cotton passage the widest, and the rouleau being suitable for is the biggest；The cotton passage of giving of existing nipper mechanism of combing machine cannot adjust, and rouleau quantitative adjusting scope is minimum.
2, nipper is met to long stapled spinning suiting requirement.In the Detaching and Lapping stage, nipper swings forward, and the distance in the nipper plate stand groove center circular hole from the front end center of circle and the groove center distance away from nipper plate stand pin joint P determine the scope of combing machine spinning suiting fibre length.Owing to mechanism limits, existing combing machine nipper cannot processing length at the fiber of more than 35mm.
3, ensure that nipper does not collides with cylinder.In carding process, the carding isolation distance between cylinder and nipper plate has considerable influence to Cylinder Carding effect, and spinning enterprise is for pursuing more preferable spinning quality, and often separation being spaced is contracted to 8mm, and carding isolation distance is contracted to 0.3mm.But, along with the retrogressing of nipper in carding process, carding isolation distance is gradually reduced, easily occur that nipper plate not yet exits the circular arc scope of cylinder pin tooth, the phenomenon that cylinder produces the most from below, causes and collides with cylinder pin tooth bottom nipper plate, and expensive nipper, cylinder are directly scrapped.
The patent of Application No. 201180045511.X discloses the clamp assemblies of a kind of combing machine, as shown in Figure 1, the problem of nipper collision during what it solved is combing machine uses at the end of 130 ° of big cambered surface Cylinder Cardings cylinder end and forward swing, but in use find: 1, the cotton guiding plate in this grip module is fixed, nipper plate, cotton guiding plate and feed roll motor up and down, longitudinal separation can not adjust, the processing of different-thickness rouleau cannot be adapted to cotton passage；2, being limited by nipper mechanism, the distance in the nipper plate stand groove center circular hole from the front end center of circle and the groove center distance away from nipper plate stand pin joint P cannot meet more than 35mm long stapled combing processing；3, the nipper plate of this grip module raises height h,Too high (up to 5mm), raises initial point too small away from nipper plate front end distance S, and elevation angle is excessive causes nipper plate pincers lip too small with distance L of elevated plane, and nipper plate pincers lip is forced pressure at nippers and easily ruptured, and causes nipper, carding element suitable to scrap；4, this grip module can not solve when separation is spaced too small, the problem that after nipper, during pendulum, cylinder produces collision nipper from below；
Application No. 201410454438.7 patent proposes the nipper mechanism of combing machine of a kind of feed roll motor position adjustable for different cultivars fiber, is achieved by replacing parts and processes long stapled combing；But still suffer from some problems: (1) this nipper carries out needing frequently to change during long and short fiber process eccentric bushing and pawl base, often occur that eccentric bushing loosens, pawl base and feed roll motor poor fit, feed roll motor cannot be smoothed out to the abnormal phenomenas such as cotton, combing processing；(2) feed roll motor is fixed as 8mm with the distance of cotton guiding plate, when combing machine feeding rouleau thickness (rouleau is quantitative) changes, upper and lower, longitudinal separation between feed roll motor to feed plate cannot corresponding adjust, it is difficult to ensure that combing machine cotton feeding is smooth, mask work difficulty, output web quality is caused to deteriorate.Practice process proves, this nipper still cannot solve the combing processing problems of long fibre and different-thickness lap.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of modern comber nipper mechanism, solve Application No. 201180045511.X and 201410454438.7 nipper plate when rouleau thickness changes, cannot adjust to cotton passage accordingly, eccentric bushing loosens, ratchet causes with feed roll motor poor fit combing machine cotton feeding, mask work are difficult, when output web ruptures and cylinder spaces too small with nipper plate, nipper fallback procedures is collided with cylinder, the technical problem of nipper plate pincers lip easy fracture；Reach to be adjusted flexibly to cotton passage to adapt to the change of rouleau thickness, ensure that combing machine smooth processing long stapled to more than 35mm, while preventing nipper from colliding with cylinder, avoid nipper plate pincers lip fracture, both ensure that equipment ran safety, and reduced again entreprise cost.
In order to achieve the above object, the technical scheme is that a kind of modern comber nipper mechanism, including nipper plate stand, nipper plate stand front is fixed with nipper plate, and the middle part of described nipper plate end face is provided with trapezoidal groove, is provided with cotton guiding plate in trapezoidal groove, cotton guiding plate anterior in arc-shaped, afterbody horizontal, cotton guiding plate afterbody is fixed on nipper plate stand, and cotton guiding plate is arranged over feed roll motor, and nipper plate stand two ends are provided with the groove placing feed roll motor；The front end of described nipper plate bottom surface is plane, and plane rear is gradually raised by arc transition, and nipper plate stand is hinged with nippers conjunction bottom.
