Description

A kind of double roller mills of amino film plastics granulation

Technical field

The present invention relates to a kind of roller mill, especially a kind of amino film plastics granulate the roller mill in field.

Background technology

Advancing by leaps and bounds with domestic steel industry for many years, many roller mills also with rising energetically.There are eight rollers, 12 rollers, 20 rollers etc..Many roller mills are made up of roller cage and roll stacks, support roller in roll stacks is back lining bearing, with reconditioning bearing or bearing can be changed after bearing wear, cost is relatively low, and intermediate calender rolls and working roll are after a period of operation, surface abrasion is coarse, it is necessary to reconditioning roller surface, roller diameter and effective hardness top layer are being gradually decreased, and existing roller mill material is to urea-formaldehyde moulding powder（Amino film plastics are commonly called as）Resist wear-resisting, corrosion resistance not enough, roller mill surface smoothness is caused to destroy and sizing, and constantly have variegated generation, roll top layer must just scrap after ten a few to tens of millimeters, and a roll cost wants tens of thousands of members to ten tens of thousands of yuans, great economic loss is caused, and the support Adjustment precision of existing roller mill is poor, self-lock ability is bad.

The content of the invention

The technical problems to be solved by the invention are to provide a kind of double roller mills of amino film plastics granulation, and the working roll of the roller mill resists wear-resisting, corrosion resistance strong, and working roll turnover rate is low, high working efficiency, low cost of manufacture.

In order to solve existing technical problem, the technical solution adopted by the present invention is：A kind of double roller mills of amino film plastics granulation, including roller cage, the roller assembly above roller cage, the blanking device being arranged on below roller assembly and the rotating actuator for being arranged on the roller assembly side and driving roller assembly to rotate.

A kind of above-mentioned double roller mills of amino film plastics granulation, described roller assembly includes the first roll and second roll be arrangeding in parallel, the first travelling gear and the second travelling gear is fixedly connected with the same side of the first roll and second roll.

A kind of above-mentioned double roller mills of amino film plastics granulation, the rotating actuator includes intermeshing first driven gear and the second driven gear, first driven gear is meshed with the first described travelling gear, and the second driven gear is meshed with second travelling gear；First driven gear is connected with the output shaft of motor.

Electric hot plate is equipped with a kind of above-mentioned double roller mills of amino film plastics granulation, the roll circle of the first roll and second roll.

The discharge end for corresponding to the roller assembly on a kind of above-mentioned double roller mills of amino film plastics granulation, the roller cage is provided with feed opening.

A kind of above-mentioned double roller mills of amino film plastics granulation, described blanking device includes hopper, knife rest and the blade being arranged on knife rest, knife rest is arranged in hopper, blade is opposite with the side face of the first roll and second roll, and the hopper is fixedly connected with the feed opening on the roller cage.

Beneficial effects of the present invention are：The working roll of the roller mill resists wear-resisting, corrosion resistance strong, and working roll turnover rate is low, high working efficiency, low cost of manufacture.

Embodiment

Further understand and recognize, coordinate detailed description to preferred embodiment and accompanying drawing, be described as follows：

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of double roller mills of amino film plastics granulation, including roller cage 1, roller assembly 2 above roller cage, the blanking device 3 being arranged on below roller assembly and the rotating actuator 4 for being arranged on the side of roller assembly 2 and driving roller assembly 2 to rotate.

Roller assembly 2 includes the first roll 21 and second roll 22 be arrangeding in parallel, and the first travelling gear 23 and the second travelling gear 24 are fixedly connected with the same side of the first roll 21 and second roll 22.

The structure of rotary drive machine 4 includes the intermeshing driven gear 42 of first driven gear 41 and second, and first driven gear 41 is meshed with the first travelling gear 23, and the second driven gear 42 is meshed with the second travelling gear 24；First driven gear 41 is connected with the output shaft of motor, drives first roll 21 to rotate by the first driven gear 41, and the second driven gear 42 engaged with the first driven gear 41 drives second roll 22 to rotate.

Further understand as the present invention, electric hot plate is equipped with the roll circle of first roll 21 and second roll 22；Discharge end on roller cage 1 corresponding to roller assembly 2 is provided with feed opening 11.

Blanking device 3 includes hopper 31, knife rest 32 and the blade 33 being arranged on knife rest 32, knife rest 32 is arranged in hopper 31, blade 33 is opposite with the side face of first roll 21 and second roll 22, and the hopper 31 is fixedly connected with the feed opening 11 on roller cage.

In the present invention, block amino film plastics enter the feed end of roller assembly 2 by feed arrangement, pass through the extruding of the first pressure roller 21 and the second pressure roller 22, become slabbing, enter in hopper 31, and entered along feed opening 11 in roller cage 1, because the electric hot plate in roll circle is heated to amino film plastics always so that the amino film plastics processed are in relative temperature constant state；Due to amino film plastics, in compacting, viscosity is larger, appear in the phenomenon of adhesion amino film plastics on roll, when there is this phenomenon, by the blade 33 and the circumferential contact of first roll 21 and second roll 22 of blanking device 3, the amino film plastics on roll will be sticked to and removed and as hopper 31 is entered in roller cage 1.

The working roll of this roller mill is wear-resisting from resisting, and the stronger mould steel of corrosion resistance is material, and double roller diameters are 350-600mm, using this roller mill, are greatly improved urea-formaldehyde moulding powder（Amino film plastics are commonly called as）The intensity of grain forming product.By the particle being made after the roller mill roller sheet, the intensity of shaped article is than existing national standard（150-180）Improve 20%-40%.Meet international standards more than 180.Lower the powder rate ratio produced by urea-formaldehyde moulding powder is granulated by screw rod simultaneously,（Lower 10%-20% before comparable compressing tablet）So as to reach raising yield, lower the effect of energy consumption.

General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.It should be understood by those skilled in the art that; the present invention is not limited to the above embodiments; the principle of the simply present invention described in above-described embodiment and specification; various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, and these changes and improvements are both fallen within the range of claimed invention.The protection domain of application claims is defined by appending claims and its equivalent.
