Description

Technical Field

[0001] This utility model belongs to the field of rubber processing technology, and in particular relates to an ethylene propylene rubber polymer granulation device. Background Technology

[0002] Ethylene propylene rubber (EPR) is a synthetic rubber with ethylene and propylene as its main monomers. It is widely used in automotive parts, waterproof building materials, wire and cable sheathing, heat-resistant hoses, tapes, automotive seals, lubricant additives, and other products. With advancements in industrial production, the demand for EPR products is constantly increasing. In some production fields, EPR granules are required as raw materials. A search revealed a patent with application number 202120676515.9, which discloses a rubber granulator. The granulator body is a cylindrical hollow component. An electric heating layer is fixedly installed on the outer wall of the inner cavity of the granulator body. A conveying shaft rotates between the left and right walls of the granulator body. A spiral blade is fixedly connected to the conveying shaft. The left end of the conveying shaft extends from the left end of the granulator body and is powered by a conveying motor. A feed inlet is fixedly installed on the top left side of the granulator body. An annular output groove runs through the right wall of the granulator body, and three connecting blocks are arrayed within the output groove.

[0003] However, in actual use, the applicant found that during the process of heating and melting the rubber inside the granulator body through the electric heating layer inside the granulator body, the rubber raw material could not be stirred, which made it impossible for the rubber to be heated and melted evenly, reducing the efficiency of rubber heating and melting, and thus reducing the granulation efficiency. In view of this, we propose an ethylene propylene rubber polymer granulation device. Utility Model Content

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A granulation device for ethylene propylene rubber polymer includes a housing 1, a cylinder 4 fixedly connected to the top of the housing 1, a feeding port 42 provided at the top of the cylinder 4, support rods 41 symmetrically arranged at the bottom of the cylinder 4, and the lower ends of the support rods 41 fixedly connected to the top of the housing 1. A second motor 5 is fixedly mounted on the top of the cylinder 4, the output end of the second motor 5 extends into the interior of the cylinder 4 and is coaxially fixed to a stirring shaft 9, which is equipped with stirring blades 91. By driving the second motor 5 to rotate the stirring shaft 9 and the stirring blades 91, the ethylene propylene rubber polymer inside the cylinder 4 can be stirred, causing the ethylene propylene rubber polymer to granulate. The more uniform heating of propylene rubber improves the efficiency of ethylene propylene rubber melting, thereby accelerating the granulation efficiency of the ethylene propylene rubber polymer. An electric heating plate 45 is fixedly installed on the inner wall of the cylinder 4. A discharge pipe 43 is installed at the lower part of the cylinder 4 and is connected to the interior of the box 1. The ethylene propylene rubber polymer melted inside the cylinder 4 can be introduced into the interior of the box 1 through the discharge pipe 43. An electric heating plate is installed inside the box 1 for preheating the interior, preventing the ethylene propylene rubber polymer from cooling too quickly. A discharge valve 44 is fixedly fitted onto the discharge pipe 43. A first motor 2 is fixedly installed on one side of the housing 1. The output end of the first motor 2 extends into the interior of the housing 1 and is coaxially fixed with a rotating shaft 8. A spiral blade 81 is sleeved and fixed on the rotating shaft 8. A connecting pipe 11 is fixedly installed on the side of the housing 1 away from the first motor 2. A granulation cylinder 6 is sleeved on the end of the connecting pipe 11 away from the housing 1. A granulation disc 10 is fixedly abutted against the interior of the granulation cylinder 6 through the connecting pipe 11. Granulation holes 101 are evenly opened on the granulation disc 10. A third motor 7 is fixedly installed on the side of the granulation cylinder 6 away from the connecting pipe 11. A controller 3 is fixedly installed on the top of the housing 1. The controller 3 is electrically connected to an external power source via wires. The first motor 2, the second motor 5, the third motor 7, the discharge pipe 43, and the electric heating plate 45 are electrically connected to the controller 3 via wires. The output end of the third motor 7 extends into the interior of the granulation cylinder 6 and is fitted with a cutter 71. The cutter 71 is in contact with the end face of the granulation disc 10. The cutter 71 can cut the strip-shaped ethylene propylene rubber polymer extruded from the granulation hole 101 into granulated ethylene propylene rubber polymer. A discharge pipe 63 is provided on the granulation cylinder 6 below the cutter 71. Support legs 14 are fixedly provided at the four corners of the bottom of the box body 1.

[0022] Guide rods 13 are symmetrically fixed on the housings 1 on both sides of the connecting pipe 11. The guide rods 13 movably pass through the guide sleeves 61 symmetrically arranged on both sides of the granulation cylinder 6. A threaded pipe 12 is fixedly installed on the housing 1 above the connecting pipe 11. A screw 62 is rotatably connected to the upper part of the granulation cylinder 6 through a bearing support. One end of the screw 62 is threaded into the threaded pipe 12, and an adjusting handle 621 is fixedly installed on the other end of the screw 62. A stepped groove that mates with the connecting pipe 11 is opened on the side of the granulation cylinder 6 near the connecting pipe 11. A sealing ring is provided at the end of the connecting pipe 11 away from the housing 1 to seal the contact point between the connecting pipe 11 and the granulating disc 10. The granulating disc 10 is inserted into the stepped groove. By rotating the screw 62 counterclockwise, the granulating cylinder 6 is moved away from the connecting pipe 11, so that the housing 1 and the granulating cylinder 6 are separated. The granulating disc 10 can be removed from the inside of the granulating cylinder 6, which makes it convenient for personnel to replace the granulating disc 10 with different granulation hole 101 apertures, so as to realize the manufacturing of ethylene propylene rubber polymers with different particle sizes.

[0023] Working principle: During use, a certain amount of ethylene propylene rubber polymer raw material is fed into the cylinder 4 through the feeding port 42, and the electric heating plate 45 is energized. The electric heating plate 45 heats the raw material inside the cylinder 4. At the same time, the controller 3 drives the second motor 5 to rotate the stirring shaft 9 and the stirring blade 91. The stirring blade 91 stirs the raw material inside the cylinder 4, making the raw material melt more evenly. After the raw material melts, the discharge valve 44 is opened to discharge the melted ethylene propylene rubber polymer inside the cylinder 4 into the box 1 through the discharge pipe 43. Before discharge, the electric heating plate inside the box 1 can be used to preheat the inside of the box 1 to prevent the ethylene propylene rubber polymer from cooling too quickly. Then, the first motor 2 is driven to rotate the rotating shaft 8 along with the spiral blade 81. The spiral blade 81 stirs the raw material inside the box 1. Ethylene propylene rubber polymer is pushed from the connecting pipe 11 to the granulation disc 10 and extruded into strips through the granulation holes 101. During extrusion, the cutter 71 is driven by the third motor 7 to rotate, cutting the strips into granules, which are then discharged from the discharge pipe 63. When different granules are needed, the adjusting handle 621 can be manually rotated counterclockwise to rotate the screw 62. The screw 62 rotates inside the threaded pipe 12, causing the granulation cylinder 6 to move outward along the guide rod 13, separating the connecting pipe 11 from the granulation cylinder 6. The granulation disc 10 can then be removed from the granulation cylinder 6 and replaced with a granulation disc 10 having granulation holes 101 of the required particle size, thus enabling the manufacture of ethylene propylene rubber polymers of different particle sizes.
