Description
Technical field
The utility model relates to technical field of spinning equipment, especially novel draft of drawing frame leather roller pressurizing device.
Background technique
Due to draft of drawing frame leather roller pressurizing device existing defects in the design, equipment during operation, drawing-off pressurization
Pressurization mandrel in device is when giving roller pressure volume, since roller is in the state of running at high speed, pressuring shaft bottom and skin
The contact surface of roller stress point is small, and the roller of high-speed motion is due to self-vibration itself, and roller is in the operating of dynamic stress, roller
Pressurization is easily walked about before and after mandrel position, causes roller pressure at two ends irregular, left and right travelling, and roller is high in the case where eccentricity runout
Speed operates, and the cotton net moved in counter extensioin area not can be effectively controlled, and causes item is dry to deteriorate, and cotton net Fiber Straightness is poor, easily appearance
Mechanical wave, Unevenness CV % value is big, and sliver is also easy to produce thickness section and various yarn defects, seriously affects yarn quality and production efficiency.
Summary of the invention
The purpose of this utility model provides that a kind of structure is simple, failure rate is low aiming at defect of the existing technology,
It is easy to maintenance, the stable novel draft of drawing frame leather roller pressurizing device of quality.Its technical solution are as follows: set in roller pressure volume core sleeve
There is gas spring, gas spring passes through pressing arm connection pressurization fixture nut and automatic stop bolt, roller are located in roller pressure volume core sleeve
And be fixed in pressing arm, pressing arm gas spring supporting and fixing is located in pressing arm, and pressurization hook is arranged on pin shaft, roller setting
In the top of roller, pressing arm is equipped with pressing arm axis hole, is equipped with pressurized handgrip in the left end of device, roller is equipped with 4.
The utility model replaces all pressuring shafts, has invented novel drawing-off roller pressure volume mandrel suit
It sets, the axis shape contact point of pressurize mandrel bottom and roller bearing fuse is changed to plastic sleeve, the bearing fuse at roller both ends
Seamless unoccupied place covers in mandrel axle sleeve, is pressed into contact face by axis point stress and is changed into circumference stress, forced area increases, and position is not
It can gently meaning movement, new pressurized mandrel shaft sleeve device all be integrally attached in pressing arm, 4 root skin roller of front and back is all covered in pressing arm again
In each roller pressure volume core sleeve on, weight of the pressing arm due to more increasing 4 root skin rollers, lift is excessively heavy when putting, thus
It has installed gas spring assembly in pressing arm additional, can easily 4 root skin rollers while have been lifted when pressing arm is put in lift, and in the position of high point
Continued support facilitates tender's counter extensioin position and operates and clean.The pressure divergence at roller both ends is effectively controlled,
Pressure output is steady, and tender's lift is put light easy to operate, and it is obvious to change rear effect, stable product quality.
The utility model the utility model has the advantages that design is reasonable and practical, clean, be easy to maintenance by installation, time saving and energy saving, reduces and matches
Part expense improves the quality of product, improves economic benefit, and popularity is suitble to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, novel draft of drawing frame leather roller pressurizing device, mainly by automatic stop bolt 1, pressurization fixture nut 2 plus
Pressure arm 3, pressing arm axis hole 4, pressing arm gas spring bearing 5, gas spring 6, roller 7, roller 8, roller pressure volume core sleeve 9, pressurization
Hook 10 and pressurized handgrip 11 are constituted；Roller pressure volume core sleeve 9 is equipped with gas spring 6, and gas spring 6 passes through the connection pressurization of pressing arm 3
Fixture nut 2 and automatic stop bolt 1, roller 7 are located in roller pressure volume core sleeve 9 and are fixed in pressing arm 3, pressing arm gas spring
5 fixation of bearing is located in pressing arm 3, and pressurization hook 10 is arranged on pin shaft, and roller 7 is arranged in the top of roller 8, in pressing arm 3
Equipped with pressing arm axis hole 4, pressurized handgrip 11 is equipped in the left end of device.
The utility model process flow:
When pressurized operation, pressing arm 3 and (interlocking plant) are gently depressed, pressurization hook 10 is hung on pin shaft, will be pressurizeed
Handle 11 presses the operating that can drive (position shown in upper figure is in working condition).Pressurized handgrip 11 is pulled when release forward, arrives and adds
After pressure hook 10 is detached from pin shaft, entire pressing arm 3 is lifted up automatically under 5 effect of gas spring bearing, rests on pressing arm 3
Any position of side facilitates tender to operate and clean.
