Description
Technical field:
The invention belongs to technical field of textile machine, relate to the rotary rubbing type clamp device that a kind of device, particularly a kind of automatic doffer that can simulate the clamping spool of manual dematron action used.
Background technology:
At present, adopt except the fine spining machine of some advanced persons' big number of spindles collective doffs in China, being no less than 95% spindle is installed on 480 ingots and the following fine spining machine, these little number of spindles fine spining machines are except small part employing electro-automatic doffer doffs, most of fine spining machine still adopts the mode of manually doffing, the recruitment of manually doffing is many, and labour intensity is big, and production efficiency is low.At present, China wide geographic area textile enterprise recruitment difficulty, the recruitment cost improves constantly, and market increases day by day to the demand of automatic doffer; Fine spining machine in spinning process for realize active volume around, between spindle and the spool relative motion can not be arranged, therefore, need the inlay resultant force that keeps certain between ring bobbin and the spindle blade, this gives to doff and has caused certain difficulty, and what at first need to solve when automatic doffing throws off the chimeric of spindle and bobbin with spool exactly.In the prior art, part electro-automatic doffer pipe drawing device has the pre-loose function of spool, can reduce tube drawing power and machine power consumption; Part electro-automatic doffer pipe drawing device does not have pre-loose function, adopt the mode of direct tube drawing to finish the tube drawing action by strengthening tube drawing power, this is concerning the polished rod spindle, tube drawing power is very big, surpass 30kg according to the document briefing, the power consumption of the dolly that doffs is increased, and parts damage, and therefore pull out yarn for the polished rod spindle and adopt the mode of the pre-pine of elder generation better.Application number is that 201210451312.5 Chinese patent discloses " the automatic pipe drawing device of a kind of doffer ", but this device lacks pre-loose function, can not satisfy the demand.So design has proposed a kind of brand-new rotary rubbing type clamp device with pre-loose function, adopt the manual rubbing of revolving of parallel-crank mechanism simulation when clamping spool to do, make spool throw off the chimeric of spindle and bobbin, before tube drawing, realize pre-loose function, market prospects and social demand meaning are arranged very much.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists, seek to design a kind of rotary rubbing type clamp device for automatic doffer, utilize the movement characteristic of parallel-crank mechanism, in top clamping spool, rely on the manual rubbing work that revolves of the tandem relative motion simulation of long and short two clamping plate, overcome the inlay resultant force between spool and the spindle, finish the pre-loose function of spool.
To achieve these goals, the present invention adopts two groups to clamp the air cylinder driven push pedal and promote long crank-swinging through roller, forms long clamping plate and the short clamping plate clamping spool close to each other of feed collet, and simultaneously, long clamping plate are mobile backward, and short clamping plate move forward; Long clamping plate and short clamping plate and opposite both sides that also act on spool respectively of frictional force equal and opposite in direction, direction between the spool, spool is produced a turning moment, under the turning moment effect, the spool disengagement is chimeric with spindle, inlays the polyurethane fixture block to increase the frictional force between feed collet and the spool in feed collet.
