The medial surface of keeping away from chamber door 3 of box 1 is semi-circular structure, the structure of sieve 6 and the medial surface structure phase-match of box 1, the 1 inner wall of box not only can be laminated in the semicircular design of sieve 6, make the impurity at 6 tops of sieve can not follow the 1 inner wall landing of box, semi-circular structure itself just possesses certain material effect of gathering simultaneously, make the burr impurity of mixed and disorderly distribution at 6 tops of sieve can landing to 16 departments of porthole fast, and finally fall to 18 bottoms of delivery box.

One side of the feeding box 18 is provided with an air blower 19, an air outlet of the air blower 19 is opposite to the top of the rotating rod 15, a discharging hole 20 is arranged at the air outlet of the box body 1 opposite to the air blower 19, so that large-particle burrs at the top of the rotating rod 15 and at the top of the spiral blade 29 can be blown away from the top of the spiral blade 29 through the air blower 19 and enter the discharging hole 20, one end of the discharging hole 20 far away from the rotating rod 15 is provided with a corrugated pipeline 21, the other end of the corrugated pipeline 21 is provided with a clamping ring plate 22, a through hole 26 is arranged in the clamping ring plate 22, the corrugated pipeline 21 is blown by wind power of the air blower 19 to be enlarged in volume and can move towards the end of the roller 7, the inside of the end cover 28 is provided with a butt joint hole 12, the outer surface of the butt joint hole 12 is provided with an annular fixing plate 24, the inner side surface of the clamping ring plate 22 is clamped with the outer side surface of the annular fixing plate 24, the butt joint hole 12 is matched with the through hole 26, and is clamped with the annular fixing plate 24 by means of the clamping ring plate 22, the drum 7 can be well limited, meanwhile, the butt joint hole 12 is communicated with the through hole 26, large-particle burrs in the discharge hole 20 can quickly reach the through hole 26 along the corrugated pipeline 21, and finally enter the drum 7 along the butt joint hole 12 to impact and crush plastic inside the drum, the annular air bag 23 is arranged on the inner surface of the clamping ring plate 22, thermal expansion gas is arranged inside the annular air bag 23, when the box body 1 is in a normal-temperature environment, the thermal expansion gas in the annular air bag 23 expands due to thermal expansion and contraction, the volume of the annular air bag 23 is increased, the through hole 26 is blocked, the large-particle burrs inside the corrugated pipeline 21 cannot be discharged, when the box body 1 is filled with liquid nitrogen and the temperature is reduced, the thermal expansion gas in the annular air bag 23 is reduced in volume due to the thermal expansion and contraction principle, and the annular air bag 23 can not only wrap and clamp the inner wall of the annular fixing plate 24, meanwhile, the opening of the through hole 26 can be enlarged, so that large-particle burrs in the corrugated pipeline 21 can enter the butt-joint hole 12 along the through hole 26 and finally enter the inside of the roller 7.

During the use,

open chamber door

3, 4 corotation of controller 2 control axis of rotation, axis of rotation 4 drives cylinder 7 and rotates out, open end cover 28, and pour the plastic inside cylinder 7, cover

end cover

28, 4 antiport of controller 2 control axis of rotation, when cylinder 7 rotates and just to the discharge gate 20 stall to butt joint hole 12, close chamber door 3 this moment, controller 2 control air-blower 19 starts this moment, air-blower 19 blows corrugated pipe 21 volume grow with the help of wind-force, and to the removal of cylinder 7 end, and final joint crown plate 22 inner wall and the cooperation of 24 outer walls contacts of annular fixed plate, thereby can support spacingly to cylinder 7 top, and make cylinder 7 can take place to rotate under the drive of rotation motor.

Meanwhile, the controller 2 controls the pump body 25 to start the liquid nitrogen in the coolant pumping box 8 to be discharged into the box body 1 along the connecting pipe 9, and the liquid nitrogen is uniformly distributed in the box body 1 by means of the spray head 10, so that the temperature in the box body 1 is reduced to the required low-temperature environment, namely minus 40 ℃.

s5, due to the principle of expansion with heat and contraction with cold, the volume of the annular air bag 23 is reduced, the annular air bag 23 is clamped with the inner side surface of the annular fixing plate 24, and the opening of the clamping annular plate 22 is enlarged;

s6, the controller 2 controls a rotating motor inside the fixed seat 5 to start to drive the roller 7 to rotate, and plastic inside the roller 7 contacts and collides with the inner wall of the roller 7 under the action of centrifugal force to remove burrs;

s7, dropping the burrs to the top of the sieve plate 6 along the filtering holes 11 on the outer surface of the roller 7;

s8, the controller 2 controls the driving motor 14 to start, the output shaft of the driving motor 14 drives the rotating rod 15 to rotate, and the rotating rod 15 rotates to drive the helical blade 29 to rotate;

s9, the spiral blade 29 is in extrusion contact with the end part of the sieve plate 6 in the rotating process and drives the end part of the sieve plate 6 to move upwards, when the end part of the sieve plate 6 reaches the maximum value and is separated from the contact with the spiral blade 29, the buffer spring 13 drives the end part of the sieve plate 6 to restore to the original position under the action of the self elasticity, the sieve plate 6 performs high-frequency vibration in the box body 1, and the burr impurities on the top of the sieve plate 6 are sieved;

s10, helical blade 29 rotate and drive the large granule burr of pay-off case 18 bottom and rise to dwang 15 top, and inside air-blower 19 drove the large granule burr along discharge opening 20, through-hole 26 and butt joint hole 12 entering cylinder 7 with the help of wind-force, the plastic striking burring in large granule burr and the cylinder 7.

Wherein, the plastic in the cylinder 7 is blown to the wind-force that air-blower 19 produced carries out unordered motion, and the wind-force carries burr impurity to reach the top of sieve 6 along filtration pore 11, finally along the exhaust vent discharge.

The method for intelligently removing the plastic burrs at low temperature is discussed, so that the optimal use method of the device is obtained, the deburring effect is improved, the deburring effect is ensured, the optimal plastic is obtained, the labor intensity is greatly reduced, and the resources are saved.
