Description

The transmission belt swelling device of carding machine

Technical field

The utility model belongs to field of non-weaving textile machinery technology, and in particular to a kind of transmission belt swelling device of carding machine.

Background technology

Aforesaid carding machine is also referred to as carding machine, is a part in complete on-woven Production equipment.Such as industry Known to boundary, opener, combing are mainly included without spinning equipment for producing the complete of the on-woven product such as non-woven fabrics or on-woven felt Machine, lapping machine and needing machine（Or spun-laced machine）, the function of carding machine be by by the on-woven fiber combing after opener simultaneously Lapping machine lapping is fed to, send needing machine or spun-laced machine thorn to close after lapping machine lapping, form on-woven product.

Can be seen in disclosed Chinese patent literature with regard to the technical information of carding machine, such as Authorization Notice No. CN1313660C（Multichannel is fed for the flat caiding machine of fiber in the form of fiber mat）、CN2816061Y（Full securing cover plate cotton carding Machine）、CN100510211C（A kind of feeding of carding machine and combing system）、CN105648582A（A kind of comb of on-woven fiber Reason machine equipment）、CN104342788A（A kind of high-performance fiber carding machine and its carding method of combing blend fabric）、 CN104911817A（Full securing cover plate formula carding machine suitable for Nonwovens Line）、CN102505201A（Roller lid The hybrid carding machine of plate）And CN104153048A（Novel carding machine）, etc..

Being not limited to the common feature of carding machine exemplified above is：Be respectively provided with custom be referred to as main cylinder main cotton carding roller, With the card stripper with paired form appearance and working roll, breast cylinder, transmission belt cornerite roller, transmission belt swelling device and transmission Band, under the work of actuating unit, aforementioned main cotton carding roller, card stripper, breast cylinder and transmission belt cornerite roller is made simultaneously by transmission belt Motion and by the expansion tightening wheel in the structural system of transmission belt swelling device make transmission belt be held in technique required by tensioner shape State.Specifically, when relaxed condition occurs in transmission belt, made at transmission belt by the Reasonable adjustment to transmission belt swelling device In good motion state, the passive motion caused with avoiding skidding, on the contrary same example.

The structure of the transmission belt swelling device in prior art is：Arrange a pair of bearing on the wallboard of carding machine to lead Rail, bearing block and a pair of bearing slide are coordinated, and on the top of bearing block（It can also be bottom）Connect an axle Bearing adjusts one end of screw rod, and the other end of bearing block adjustment screw rod is rotationally connected on wallboard, and expansion tightening wheel passes through expansion tightening wheel Axle is rotatably supported on bearing block.When belt sag is driven, then adjust aforesaid bearing block and adjust screw rod, by the bearing block Adjustment screw rod drives bearing block to follow aforesaid a pair of bearing guide rail displacement, while driving tension wheel shaft corresponding positions by bearing block Move, finally expansion tightening wheel is driven by tension wheel shaft, make transmission belt be in rational tensioner state.When the situation of tension occurs in transmission belt When, then bearing block adjustment screw rod is operated with the rightabout of aforementioned regulation.Although this structure disclosure satisfy that to passing The tensioner degree adjustment requirement of dynamic band, but there is following shortcoming；First, due to carding machine transmission belt it is more tediously long, and with The passage elongation degree of use time is more serious, thus only with the bearing block adjustment screw rod being connected between bearing block and wallboard Adjustment to bearing block is difficult to or even cannot confiscate the lax surplus of transmission belt；Second, bearing block is locked in due to lacking The function of the position after adjustment, but due to the work kinetic energy of carding machine it is relatively large, thus in carding machine course of work middle (center) bearing Seat more or less occurs floating situation, the final tensioner effect for affecting expansion tightening wheel to transmission belt.

Although the technical information of transmission belt swelling device can be seen in disclosed Chinese patent literature, typically such as CN2027665735U recommends have " a kind of transmission belt swelling device ", CN202946630U to be provided with a kind of " belt transmission caching Tensioner wheel apparatus " and CN202883909U（A kind of lever type belt tension pulley mechanism）, etc., but these patent formulas are not Be enough to solve above mentioned two technical problems.

For aforementioned technical problem, the applicant has made positive and beneficial exploration, defines finally and will be described below Technical scheme and the test site in the case where secrecy provision is taken in the applicant tested, as a result prove practical Feasible.
