Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction in inventive embodiments
Attached drawing, the technical solution in inventive embodiments is clearly and completely described, it is clear that the embodiments described below are only
It is only invention a part of the embodiment, and not all embodiment.Based on the embodiment in invention, those of ordinary skill in the art exist
All other embodiment obtained under the premise of creative work is not made, the range of invention protection is belonged to.
As shown in Fig. 1 to 2, a kind of material supercharging device provided in an embodiment of the present invention includes tube body 1, and tube body 1 is using resistance to
Material production, 1 inner hollow of tube body are ground, 1 inner wall of tube body is equipped with the conveyor screw 2 of backspin.1 outer wall of tube body is successively arranged from top to bottom
Upper flange 3, central flange 4 and lower flange 5.It is fixed with the first revolving part 6 in upper flange 3, tube body upper port passes through the
One revolving part 6 is connected with the rotation of material bin 7.It is fixed with driving device on central flange 4, drives tube body 1 to revolve by driving device
Turn.The second revolving part 8 is fixed in lower flange 5,1 lower port of tube body is rotated by the second revolving part 8 with roll squeezer spout 9
Connection.The first fixed bracket 10, the first revolving part 6 and the second revolving part 8 are equipped between first revolving part 6 and the second revolving part 8
It is each attached on the first fixed bracket 10, the first fixed bracket 10 is fixed on the shell of roll squeezer spout 9.
As shown in Figure 1, the first revolving part 6 of the embodiment of the present invention is transverse bearing, the second revolving part 8 is axial bearing,
It is equipped with multiple mounting holes on the outer ring of transverse bearing and inner ring, is also equipped with mounting hole on the Shang Quan of axial bearing and lower circle, passes through
Mounting hole is convenient for the fixation with other components.The inner ring of transverse bearing is bolted with upper flange 3, under axial bearing
Circle is passed through with the first fixed bracket 10 with lower flange 5 by connection, the outer ring of transverse bearing and the upper circle of axial bearing respectively
It is bolted.The structure of transverse bearing is equal to deep groove ball bearing, is primarily subjected to radial force when tube body rotation.Axial bearing knot
Structure is equal to thrust bearing, and main function is to bear the upward reaction force that pressing materials generate when tube body 1 operates.
First fixed bracket 10 is mainly used to fixed radial bearing and axial bearing, and it is indirectly fixed to be equivalent to after two bearings are fixed
Position tube body 1, is allowed to be rotated in fixed position, while the first fixed bracket 10 is also the skeleton of entire supercharging device,
Entire material supercharging device is rigidly fixed by the first fixed bracket 10 and the shell of the roll squeezer spout 9 of lower part, while
It is connect with the material bin 7 on top by flexible connection structure 11.11 both ends of flexible connection structure in the embodiment of the present invention can weld respectively
Connect on 7 outer wall of material bin and transverse bearing outer ring or 11 both ends of flexible connection structure be respectively adopted flange and 7 outer wall of material bin and
Transverse bearing outer ring is fixedly connected.Wherein, flexible connection structure can be in expansion joint, rubber tube, plastic tube, silica gel cloth or canvas
One kind.It can play the role of absorbing expansion by the setting of flexible connection structure 11 and reduce vibration.
As depicted in figs. 1 and 2, the conveyor screw 2 of the embodiment of the present invention is the multiple spiral bars for being individually welded on inner wall, spiral
And certain length is stretched out at top, i.e. the upper end of conveyor screw 2 is higher than 1 upper port of tube body.By welding spiral in 1 inner wall of tube body
Item can be convenient for material bin blanking, and material generates downward pressure under the action of spiral, ensure the certain material pressure of lower part material.
By the way that material bin 7 is accessed in 2 upper end of conveyor screw, and conveyor screw 2 protrudes into a certain distance in material bin 7, plays to material and helps stream
Effect, tube body lower part connects roll squeezer spout 9, when due to roll squeezer operation from material bin 7 to tube body 1 again to roll surface of roller press it
Between material be filled with state, conveyor screw 2 can give one downward pressure of material of bottom automatically when tube body 1 rotates, thus instead of
Material gravity applies material pressure.There are certain spaces at 2 middle part of conveyor screw for tube body, to ensure that relatively large material also can be smooth
Pass through.
The driving device of the embodiment of the present invention includes the first sprocket wheel 12, the second sprocket wheel 13, range line shaft coupling 14 and the electricity that slows down
Machine 15, the first 12 sets of sprocket wheel are bolted to connection on 1 outer wall of tube body, and with central flange 2.First sprocket wheel 12 passes through chain
Item 16 is connected with the second sprocket wheel 13, and the second sprocket wheel 13 is connect with range line shaft coupling 14, range line shaft coupling 14 and 15 phase of decelerating motor
Even, the effect of protection equipment is primarily served.Decelerating motor 15 is mounted on the second fixed bracket 17, and the second fixed bracket 17 is fixed
On the shell of roll squeezer spout 9.When conveyor screw 2 in tube body 1 rotates, downward pressure is generated to full of its internal material
Power, thus requirement when ensure that roll squeezer operating to material pressure inside its drawing-in device.Meanwhile roll squeezer blanking it is unsmooth or
When other reasons cause material to press through big, transmission system stress is greater than the torque that range line shaft coupling 14 is set, range line shaft coupling 14
It disengages, protects the important components such as drive apparatus and bearing.
When work, driving device drives the rotation of the first sprocket wheel 12, so that the conveyor screw 2 of 1 inner wall of tube body is driven to rotate, due to
The top of conveyor screw 2 has been protruded into material bin, and under the action of the spiral of conveyor screw 2 itself, the material in material bin is forced to draw
It flows into conveyor screw and presses down, full of after material in roll squeezer spout 9, the rotation of conveyor screw 2 will generate material
Pressure, to achieve the effect that generate material pressure.After material pressure generates, conveyor screw 2 will receive reaction force vertically upward, this power
It is born by axial bearing and is passed through bolt to be transmitted on roll squeezer spout.
When a failure occurs it, such as roll squeezer putty, the reaction force that the rotation of 1 spiral inner wall body 2 of tube body generates quickly increase
Greatly, 13 stress of the second sprocket wheel in driving device is caused to increase, when the stress of driving device reaches the setting of range line shaft coupling 14
After torque, decelerating motor 15 and the second sprocket wheel 13 are disengaged, and tube body 1 stops rotating, and bigger pressure are no longer generated, when its bottom
After material discharge a part, the stress of the second sprocket wheel 13 reduces, and range line shaft coupling 14 works again, and decelerating motor 15 drives again
Dynamic second sprocket wheel 13 rotation, drives tube body 1 to start again at work rotation.
The material above roll squeezer will be arranged in by the way of rotating boosting in material supercharging device provided by the invention
Material in storehouse drains into roll squeezer and applies certain pressure, ensures the material pressure of roll squeezer and material pressure adjusts in which can be convenient.
Have the characteristics that structure it is simple, it is easy to manufacture and install, be quick on the draw, the height between material bin and roll squeezer can be greatly lowered
Degree can be by about 3 meters of former height down or so to save workshop height, i.e., roll squeezer workshop and related lifting means etc. be all
About 3 meters can be reduced accordingly, can save cost in everyways such as infrastructure, device height, plant capacity, installation costs,
It is very ideal material supercharging device.
