Specific implementation method: this gelating device has the function of agitating function and strikes off inner wall defective material and help two kinds of discharge.
1. being stretched when being stirred function by the second electric pushrod 20 in the first stirring parts 11 and the second stirring parts 12
Contracting, the inserted block 21 and socket 25 for keeping 20 output end of the second electric pushrod fixed are clamped, thus keep thread bush 10 and screw rod 9 fixed,
At this point, rotating again by driving motor 6, driving gear 7 is driven to rotate, to make the driven tooth engaged with driving gear 7
8 rotation of wheel, even if screw rod 9 rotates, to make the first stirring parts 11 and the second stirring parts 12 while rotate, to mixed in tank body 1
Material is stirred, meanwhile, it is flexible by the second electric pushrod 20, it is detached from inserted block 21 and socket 25, then by locating part 37
Third electric pushrod 39 it is flexible, push plate 40 and bayonet 46 to be clamped, to keep adjustment gear 33 fixed, make five adjusting rods
34 maintain static dynamic, are rotated by driving motor 6, since thread bush 10 is threadedly coupled with screw rod 9, and 10 bottom of thread bush is fixed
There is rotating disc 15, five slidings of adjusting rod 34 run through rotating disc 15, so realizing by five adjusting rods 34 to thread bush 10
Limit, can be rotated by screw rod 9, drive thread bush 10 to move up and down in screw rod 9, to realize 1 inner top of tank body and bottom
Mixing uniform stirring.
2. carry out striking off inner wall defective material help discharge function when, first pass through the rotation of screw rod 9, thread bush 10 be raised to upwards
Third electric pushrod 39 in highest, then locating part 37 is flexible, is detached from plate 40 and bayonet 46, meanwhile, by adjusting motor
32 rotations, drive threaded rod 31 to rotate, so that sliding block 30 be made to move in sliding mouth 36, keep rotary electric machine 28 mobile, work as rotation
It when the fixed rotate gear 27 of 28 output end of motor is engaged with adjustment gear 33, is rotated by rotary electric machine 28, drives turning gear
27 rotation of wheel drives five adjusting rods 34 to rotate so that adjustment gear 33 be made to rotate, even if sliding is applied in five adjusting rods 34
The rotating disc 15 in outside rotates, since six 17 one end of mixing page are clamped by gag lever post 18 in 15 inner arc slot 22 of rotating disc,
And gag lever post 18 is clamped far from the sliding groove 24 in 22 one end of arc groove and limit sleeve 16, and the limit sleeve 16 of 10 bottom of thread bush
It is fixed with thread bush 10, so keep six mixing pages 17 protruding with the rotation of arc groove 22 when rotating disc 15 rotates,
Even if 17 outside of mixing page is contacted with 1 inner wall of tank body, while flexible by the first electric pushrod 14, make the second stirring parts 12 downwards
It is moved to and is contacted with the first stirring parts 11, at this time six on six mixing pages 17 and the second stirring parts 12 in the first stirring parts 11
A mixing page 17 is spelled in one plane, an internal diameter and the consistent round plate of 1 internal diameter of tank body is formed, at this point, passing through limit again
Third electric pushrod 39 in part 37 is flexible, and plate 40 and bayonet 46 is pushed to be clamped, to keep adjustment gear 33 fixed, makes five
Adjusting rod 34 maintains static dynamic, is rotated by driving motor 6, realizes moving up and down for thread bush 10, so that enabled 12 are stirred
It mixes the round plate that page 17 is combined into move down, 1 inner wall defective material of tank body is struck off in realization, while can also be pressed down against mixing, makes
The mixing of gelatinization is discharged downwards faster, to effectively all take out the mixing in tank body 1, mixing defective material will not be made in tank body
1 inner wall causes to waste.
