Abstract
The utility model provides a pneumatic pressurization curvilinear back draft device. The pneumatic pressurization curvilinear back drafting device is matched with a ring frame, a roving machine and a draw frame. A pressurizer arranged in a cocket centring is a pneumatic pressurizer. The postzone is drawn along a curve so that the yarn sliver can form the grip hold arc on the surface of a back roller, the movemnet of the fiber is efficiently controlled, and the utilization ratio of the short fiber is raised. When the utility model is used, the spindle difference and the end breakage rate can be reduced, the force measuring inspection in the operating course can be reduced, and the operating cost is also reduced.
Description
The utility model relates to a kind of drafting system in the textile machine, and particularly a kind of pneumatic pressurization back zone curve high times drafting device is matched in the ring throstle of various models and extensible using on Speed frames, the drawing frame.
It is the pressurizer of pressure source with the spring that the drafting system of ring spinner of present domestic use, rocking arm are equipped with three, and three rollers of roller stand are in sustained height, in to three roller pressurizations, respectively three rollers are exerted pressure by three springs of roller, back area draft does not have the envelope angle, the straight line drawing-off.This structure is with regard to drafting system, and the fiber dispersion is big, is reflected on whole the machine, and it is big the ingot difference just to occur, influences yarn quality.The drafting system of this structure, along with passing, the spring fatiguability of service time, pressure reduces, and need often carry out pressure measurement, and debugging, maintenance load are big.External " according to the receiving " drafting system of having introduced domestic use that reaches adopts air bag, lever construction that roller is exerted pressure, and this drafting system complex structure uses the maintenance cost height.
The purpose of this utility model is at above-mentioned situation, designs a kind of pneumatic pressurization back zone curve high times drafting device.
The purpose of this utility model be achieved in that pressurizer that reel cage is equipped be vertical fixing be installed on the reel cage housing preceding, in pneumatic pressurizer and crosswise fixed be installed in back pneumatic pressurizer on the housing, pneumatic tube with before, during and after pneumatic pressurizer be fixedly connected; It is 12 °-18 ° that back, middle roller seat roller settle center on line and middle roller seat roller to settle center, front roller to settle center on line angle; The roller of the pneumatic pressurizer in back and the connection heart line and the rear roller center vertical line angle of rear roller are 60 °-80 °.
Owing to adopt technique scheme, utilize the pneumatic direct pressurization of piston, three pressurizers pressurize or release simultaneously, can keep the roller and the roller depth of parallelism, dwindle length of floating area, reduce ingot difference and end breakage rate; The back zone is a curve drawing, increased the envelope angle, sliver can form on the rear roller surface and surround the orphan, controlled fiber movement effectively, made the expansion of frictional force battery limit (BL), staple fibre is controlled preferably, fiber scatters poor little, sliver can stretch the main district of leading of closely feeding equably, improves to be woven into yarn quality, increases the total draft multiple.Use the utility model reel cage power output not influenced by service time length, not influenced by adapted roller diameter, and must shaping, maintenance cost is saved in dynamometry inspection in the process capable of reducing using.
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model side view.
Fig. 2 is the utility model reel cage schematic diagram.
Fig. 3 is a pneumatic pressurizer profile before the utility model reel cage.
