Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
Embodiment one
As shown in Figures 1 to 4, a kind of elastic circular ring side shield for roll squeezer, comprise frame and be installed on a pair roll shaft 3 in frame, the two ends of a roll shaft 3 are provided with elastic circular ring side shield wherein.
Described elastic circular ring side shield is made up of annular blocking material ring 1 and elastic pressed piece 2, elastic pressed piece 2 one end is fixed in roll shaft 3 or frame, affixed outside the other end and blocking material ring 1, blocking material ring 1 and roll shaft 3 coaxial line, blocking material ring 1 medial surface and roll shaft 3 form crusher chamber jointly, the internal diameter of blocking material ring 1 is less than roll shaft 3 diameter, and external diameter is greater than roll shaft 3 diameter.
Described elastic pressed piece 2 can be leaf spring, also can be other springs.
The operation principle of this elastic circular ring side shield is: on the one hand, and when blocking material ring 1 pressure is less than setting value, elastic pressed piece 2 makes itself and roll shaft 3 end face keep suitable distance, material 5 in crusher chamber by roll shaft 3 attrition crushing; When in material 5 extrusion process, pressure exceedes setting value to blocking material ring 1, material 5 promotes blocking material ring 1 and outwards moves along axis or deflect, blocking material ring 1 and roll shaft 3 end clearance are strengthened, and partial material 5 is overflowed from gap and its pressure is reduced, and wearing and tearing decrease.On the other hand, because blocking material ring 1 internal diameter is less than roll shaft diameter R
1, external diameter R
0be greater than roll shaft diameter R
1thus jointly can form crusher chamber with roll shaft 3, can make again material 5 roll shaft 3 pincers enter effect under with blocking material ring 1 synchronous axial system, compared with static traditional side shield, relative velocity between material 5 and blocking material ring 1 reduces greatly, thus reaches the object reducing wearing and tearing, extend the elastic circular ring side shield life-span.
Blocking material ring 1 can be monolithic construction, can be also monolithic shape structure, is convenient to install and change.Because elastic circular ring side shield is arranged on roll shaft 3, compared with traditional side shield, without the need to pulling down frame when its installation, replacing, therefore required time is short, improves the operation ratio of equipment.When blocking material ring 1 wearing and tearing need to change, adopt single block structure only can change the part that is worn, compared with needing integral replacing with traditional side shield, reduce maintenance cost.
Elastic pressed piece 2 can be leaf spring or other spring-like, and can be one or more groups that be arranged symmetrically with, it is determined according to material pressure the size of blocking material ring 1 precharge pressure.
Embodiment two
See Fig. 5 and Fig. 6, the difference of the present embodiment and embodiment one is, described elastic circular ring side shield is made up of annular blocking material ring 1 and elastic pressed piece 2, elastic pressed piece 2 one end is fixed in roll shaft 3 or frame, the other end is supported on outside blocking material ring 1, what be the center of circle at roll shaft 3 end face with roll shaft 3 end face center circumferentially evenly arranges roller 6, blocking material ring 1 inner ring sleeve is connected on roller 6, blocking material ring 1 and roll shaft 3 coaxial line, blocking material ring 1 medial surface and roll shaft 3 form crusher chamber jointly, the internal diameter of blocking material ring 1 is less than roll shaft diameter, and external diameter is greater than roll shaft diameter.
Described elastic pressed piece 2 can be spring, and can be also hydraulic part, elastic pressed piece 2 can be arranged symmetrically with one or more groups.Described roller 6 length is greater than blocking material ring 1 thickness.
Described in the present embodiment, the blocking material ring 1 of elastic circular ring side shield is socketed on roller 6, and can rotate freely along roll shaft 3 rotation direction, the relative velocity between material and blocking material ring 1 reduces, and thus also decreases the wearing and tearing of blocking material ring 1.And, supported by elastic pressed piece 2 outside blocking material ring 1, when in express material process, pressure exceedes setting value to blocking material ring 1, there is deformation in elastic pressed piece 2, blocking material ring 1 moves or deflects in whole or in part on roller 6 outside roll shaft 3 end face, and the gap between blocking material ring 1 and roll shaft 3 end face is strengthened, partial material is overflowed from gap, blocking material ring 1 pressure is reduced, and material reduces the wearing and tearing of blocking material ring 1, thus reaches the object extending side shield service life.Described blocking material ring 1 can be entirety or single block structure, thus make described elastic circular ring side shield install, safeguard very convenient.
Embodiment three
See Fig. 7 and Fig. 8, the present embodiment from the difference of embodiment one, two is: the different mounting structure adopted at roll shaft two ends blocking material rings, adopt in roll shaft one end elastic pressed piece to be fixed on roll shaft by blocking material ring, and jointly form crusher chamber with roll shaft inside blocking material ring; What the roll shaft other end was the center of circle with roll shaft end face center circumferentially evenly arranges roller, and blocking material ring inner ring sleeve is connected on roller, and blocking material ring lateral surface is connected by elastic pressed piece and roll squeezer, forms crusher chamber between blocking material ring medial surface and roll shaft end face.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
