The present invention relates to the clamping device of combing machine, it comprises can come and go mobile holding frame, and described clamping device has nipper plate and nippers and feed roller; Nippers is installed on described holding frame by the yaw swing arm, and described nippers can constitute jaw with described nipper plate in nipper lip zone, and described feed roller is installed among the bearing block that is positioned at holding frame on the nipper plate.
The DE-4216485 disclosure and description a kind of like this clamping device of combing machine, it utilizes swing arm to finish back and forth movement.Common 8 this clamping devices are installed on the combing machine.Can derive nippers from this publication utilizes swing arm swingingly to be installed on the holding frame.In the case, fulcrum bar of the spring is connected in corresponding swing arm by articulated elements, and its another end is installed on the driven eccentric part.The shown feed roller in clamping device laterally is installed in the bearing block of holding frame.Dismantle if desired feed roller (for example: for cleaning purpose, in order to penetrate the lap net, or for the replacing after wearing and tearing), in this structure, just need transfer swing arm and nippers into the position of pendulum backward.Only can upwards be taken out and without any problem at this position feed roller.Yet swing process needs special-purpose instrument hereto, because described swing takes place against the elastic force of spring.In addition, clamping device must be placed in anterior position (dead-centre position, the place ahead) to realize described swing.This be on the one hand the effort also be partly time-consuming, if particularly specific purpose tool can not be in time.
Therefore the objective of the invention is a kind of structure of eliminating these shortcomings and clamping device being provided, the simplification that dismantle feed roller this moment improves significantly.
Achieve this end by the yaw swing arm of recommending nipper, described yaw swing arm is arranged and is implemented as like this: when feed roller transverse to its axis when its operating position is transferred into off-position, each yaw swing arm is positioned at the outside that feed roller moves past the zone.Therefore can guarantee in the clamping device feed roller can free proximity.Therefore feed roller can move in each position of clamping device, and need not to utilize specific purpose tool to make each swing arm of nippers and its be brought into different positions together from its operating position to the non-operative position.Term " motion of feed roller " should be understood that: during moving, the feed roller that comprises its bearing and other parts must be moved so that be brought into the non-operative position.Term " operating position " comprises the fixed position of feed roller, in this fixed position, match with nipper plate 12 or with feeding trough in being connected nipper plate 12, constituted the feeding gap, the lap Netcom that inserts described feeding gap crosses the rotation of feed roller and is transferred.
Feed roller is transferred into term that its non-operative position is crossed over " zone " from its operating position: the space that feed roller passes in its path that leads to this position.
According to another recommendation, if each swing arm of nippers turns round below the bearing block of feed roller, then having guaranteed can free proximity.
The result is that the motion of feed roller is no longer finished by swing arm, and has obtained to the freedom in described cylinder (feed roller) zone approachingly, makes the cleaning in this zone become easy by way of parenthesis.
Also recommended the supporting-point of each swing arm be arranged in feed roller bearing block below.Consequently obtain simple structural architecture.In addition, recommended a scheme: entering at feed roller between the moving period of non-operative position, is at least in the zone that feed roller is crossed over, and the interval between each swing arm is greater than the length of described feed roller.Using this structure can make the position of each swing arm remain on the feed roller.Whole device in this suggestion can be wideer slightly.
Its another free end is installed on the fixing run-on point of frame if having that a fulcrum bar of the spring of spring element is hinged on the described swing arm, this is favourable, described fulcrum bar of the spring is made into like this: when clamping device is positioned at its rear position, described go up and nipper plate between nipper lip region generating chucking power.
Therefore optimised to the accessibility of feed roller, and the control of the nippers that is used to apply necessary chucking power and each the swing arm position under the feed roller mounting condition are complementary.
The fixed rotation point of each fulcrum bar of the spring can advantageously be arranged in below the clamping device.
Also recommended: the bearing block of feed roller has individual opening at its top, and the gap of opening equals to embed the diameter of the feed roller bearing of bearing block at least, and is provided with the device of the described opening of sealing.Therefore guaranteed simple and fast quick-detach or assembled described feed roller or described a plurality of feed roller.
Change all 8 feed rollers if desired one by one, the above is very important, and according to hitherto known structure, above-mentioned replacing is taken time very much.
If be used to seal the device of described opening is to install swingably around the axle that is fixed in holding frame, the locking of feed roller is just unclamped be simplified.
Described device can contain the double armed lever that can swing, and the first arm can be moved and be used to cover described opening this moment, and second arm can be entered in the sphere of action of spring element by swing.
In order to simplify the locking operation of double armed lever, recommend: spring element contains two sleeves, this moment, first hub being mounted was on holding frame, and held the compression spring, and was directed on first sleeve in the zone of second sleeve in open side that is closed a side.
