Abstract

The utility model designs a rubber roller lifting device of a drawing machine, including an integrated cradle with a pressure loading shaft, a rubber roller and a rubber roller bearing shell. The cradles at two sides are connected into a whole body through a connection pipe, the cradle is fixed on a frame, one end of a gas spring is connected with the cradle through a rotating axle, the other end is fixed on the frame, and the pressure loading shaft and a self-stop arm are connected with the cradle by screws. The pressure loading shaft is nested with a manipulator type ferrule, a rotary table is actively nested on the frame, a handle and a pressure loading hook are respectively connected with the rotary table, the pressure loading hook can be rotated around an axle core of the rotary table. The manipulator presents a hand shape, the upper end is nested with the pressure loading shaft, the lower end grasps tightly the rubber roller bearing shell like a finger, thus the rubber roller can not fall off, and textile workers only need to take up the whole cradle which is connected by hollow steel pipes to lift the rubber roller without additional operations.

Description

A kind of belt roller lifting device of drawing frame

Affiliated technical field

The utility model belongs to field of textile machinery, relates to the spinning slivering machinery of some product continuous reelings, comprises carding machine, combing machine and various drawing frame, the needed belt roller lifting device of particularly a kind of drawing frame integral cradle.

Technical background

Entered since 21st century, the textile technology fast development is one of important indicator of new product development at a high speed always.By drawing frame, sliver exporting speed soars 1100～1200 meters/minute from 400 meters/minute, and textile machine technology personage both domestic and external is devoted to the research and development of High-speed Drawing Frame one after another.Drafting roller (also deserving to be called roller) heating is to hinder stumbling-block at a high speed always, adopts the major diameter roller to help reducing temperature rise, and roller rises and falls with integral cradle and then helps roller heat radiation and block lathe work operation.

Drafting is the bottleneck operation in spinning technological process, is that last road has and cooperation is used, and can improve bar and do and weigh irregular critical process.Its sliver exporting speed is generally at 400～1000 meters/minute, last word has reached 1200 meters/minute, under so high speed, the roller heating is unavoidable, 50～60 ℃ is very normal, it is also more relatively that correspondingly the roller roller twines flower, twine when colored, the roller temperature is higher, and must pick up roller this moment, just can handle, if just can scald hand with the direct contact of hand, common way is to use instrument, can use but be difficult to instrument at the draw zone that so nervous many rollers are arranged, therefore, the general design of High-speed Drawing Frame has the roller that rises and falls with integral cradle.

Before this, comparatively Xian Jin belt roller lifting device has two kinds, and one is bolt-type, and one is spring.Though also can use, bigger disadvantage is all arranged.What usually external drawing frame adopted is bolt-type, and this mode is still very reliable, but the spinner must remove to stir latch with hand, seems comparatively loaded down with trivial details.Spring then is that domestic advanced drawing frame adopts, and by the fixing roller (cartridge housing) of spring of dribbling, or directly encloses the roller cartridge housing with spring wire.This mode often reliability is bad, the easy landing of roller.

Summary of the invention

The utility model overcomes the deficiency that prior art exists promptly at all drawbacks of above device, adopts the modern Design of hommization, and a kind of belt roller lifting device reliable and stable, easy and simple to handle is provided.

Technical solution of the present utility model is: a kind of belt roller lifting device of drawing frame, comprise integral cradle, roller and the roller cartridge housing of being with pressuring shaft, described both sides reel cage is in aggregates through tube connector, reel cage is fixed on the support, air spring one end links to each other with reel cage through rotating shaft, the other end is fixed on the support, pressuring shaft, automatic stop arm are connected with reel cage with screw, the described hand type cutting ferrule that on pressuring shaft, is with, the rotating disk kink is on support, handle with add pressure hook and be connected with rotating disk respectively, adding pressure hook can rotate around the turntable shaft core.

Manipulator becomes hand shape, upper end and pressuring shaft fit, and then as the finger roller cartridge housing of holding with a firm grip, roller can not drop like this in the lower end, and the spinner need only pick up the integral cradle that is connected by hollow steel pipe, and roller i.e. rise thereupon, no longer needs additional move.

The utility model compared with prior art has significant advantage and beneficial effect.By above technical scheme as can be known, the utility model has following advantage at least under the structural arrangements of excellence:

The utility model is the hand type belt roller lifting device, can guarantee that the unlikely accident of roller drops;

Because manipulator is that plastic cement is made, and is with low cost, can additionally not increase machine cost;

The utility model can be reequiped on the new used equipment of any model, helps the conservation techniques transformation funds;

The utility model can be implemented on simple eye or double-head track, also can implement on other sett frame such as carding machine, combing machine.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Referring to Fig. 1, Fig. 2, a kind of belt roller lifting device of drawing frame, comprise integral cradle 13, roller 7 and the roller cartridge housing of being with pressuring shaft 6, both sides reel cage 13 is in aggregates through tube connector, reel cage is fixed on the support, air spring 15 1 ends link to each other with reel cage 13 through rotating shaft 16, the other end is fixed on the support, pressuring shaft 6, automatic stop arm 9 usefulness screws are connected with reel cage 13, on pressuring shaft 6, be with hand type cutting ferrule 10, rotating disk 2 kinks on support, handle 1 with add pressure hook 3 and be connected with rotating disk 2 respectively, adding pressure hook 3 can rotate around the turntable shaft core.

When machine normally moves, add pressure hook 3 and hang over hollow tube connector 14 two ends, be screwed 4 and be separated by less than 1 millimeter at automatic stop arm on the integral cradle 13 9 and the automatic stop screw 8 that is contained on the pressuring shaft 6, the roller 7 with spring 5 or cylinder pressurization makes web 12 move ahead to direction of arrow drawing-off with roller 11 formation jaws.When twining cotton or other reason need lift roller 7 time, release handle 1, hook 3 comes off with rotating disk 2, and reel cage 13 upwards lifts when air spring 15 16 rotations around the shaft, and roller 7 also rises with the cutting ferrule 10 that tightly is enclosed within on the pressuring shaft 6, after operational processes is finished, draw tube connector 14 with have gentle hands, roller 7 promptly falls after rise together with reel cage 13 grades, will link up with 3 and put, turning handle 1 pressurization, mechanical recovery is normal.

On pressuring shaft 6, installed the manipulator cutting ferrule additional, manipulator becomes hand shape, upper end and pressuring shaft 6 fits, the lower end is then as pointing roller 7 cartridge housings of holding with a firm grip, roller 7 can not drop like this, and the spinner need only pick up the integral cradle 13 that is connected by hollow steel pipe 14, and roller 7 promptly rises thereupon, no longer needs additional move.

As previously mentioned, drawing frame belt roller lifting device of the present utility model is the necessary mechanism of High-speed Drawing Frame, and this device is reliable and stable, and the hommization operation is fully reflected.If belt roller lifting device is not adorned, will increase down time, and strengthen and to twine the cotton machine rate, influence production efficiency; If insecure belt roller lifting device is installed, the problem of the roller that can drop is again gently then damaged roller, influences yarn quality, and is heavy then damage important drawing-off parts such as roller, causes long parking to wait to repair.
