Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of granulator, especially to a modified plastic multi-batch granulator. BACKGROUND

[0002] Modified plastics are plastic products that have improved properties such as flame retardancy, strength, impact resistance, toughness, etc. through filling, blending, and reinforcement methods based on general-purpose plastics and engineering plastics. During granulation, the plastic is heated and melted through a screw conveyor with heating function and then extruded through an extrusion die.

At this time, the outer servo motor drives the scraper to rotate through the shaft rod, so that the scraper pushes the molten modified plastics and other raw materials stored in the feeding box to move upward along the mixing bin, avoiding long-term accumulation of the molten modified plastics and other raw materials. After the molten modified plastics and other raw materials move upward along the mixing bin, they enter the feeding port inside the guide plate, collide with the rotating stirring blade in the feeding port, and then fall off. At the same time, the molten modified plastics and other raw materials also disperse through the small holes in the scraper, avoiding long-term mixing of the same modified plastic raw materials or other raw materials, and further improving the mixing uniformity of the modified plastics and other raw materials.

DETAILED DESCRIPTION

[0030] Example 1, please refer to Figures 1-7 A modified plastic multi-batch granulator, comprising a supporting seat 1, a supporting frame 101, a granulating cylinder 102 and a feeding box 2, the supporting seat 1 is fixed with the supporting frame 101 on the left side of the upper surface, the supporting seat 1 is fixed with the granulating cylinder 102 in the middle of the upper surface through the support, the top of the granulating cylinder 102 is fixed with the feeding box 2 through the support rod, the inside of the supporting frame 101 is fixed with the hydraulic cylinder 3 and the three-phase motor 302, the inside of the feeding box 2 is fixedly provided with a mixing assembly, and the inside of the granulating cylinder 102 is provided with a granulating assembly.

[0031] The mixing assembly is composed of a guide plate 201, a top servo motor 202, a connecting shaft 203, a stirring blade 204, an outer servo motor 205, a shaft rod 206, a scraper 207 and a heating wire 208;

[0032] The uppermost inside of the feeding box 2 is fixed with the guide plate 201, the top of the feeding box 2 is fixed with the top servo motor 202, the left and right ends of the inside of the guide plate 201 are vertically embedded with the connecting shaft 203, the outer wall of the connecting shaft 203 is fixed with the stirring blade 204, the back of the feeding box 2 is fixed with the shaft rod 206, the outer wall of the shaft rod 206 is fixed with the scraper 207, and the inside of the feeding box 2 is fixed with the heating wire 208 below;

[0033] Among them, the main function of the heating wire 208 is to heat the modified plastic and other raw materials, so that they are heated and melted into liquid state;

[0034] The inside bottom end opening of the feeding box 2 has a longitudinally arranged hollow cylindrical mixing bin, the outer wall of the scraper 207 is tightly attached to the mixing bin, the bottom of the feed inlet of the vertically arranged guide plate 201 is in communication with the mixing bin, and the electric heating wire 208 is located just below the outside of the mixing bin;

[0035] The output end of the top servo motor 202 is rotationally connected between the gear plate and the connecting shaft 203 at the left and right ends of the inside of the guide plate 201, the output end of the outer servo motor 205 is rotationally connected between the transmission shaft and the shaft rod 206, and the inside opening of the scraper 207 is provided with a plurality of small holes;

[0036] After the modified plastic and other raw materials are stored in the mixing bin at the bottom of the feeding box 2, the electric heating wire at the bottom of the feeding box is used to heat and melt them. At this time, the outer servo motor 205 will rotate the scraper 207 through the shaft rod 206, so that the scraper 207 pushes the modified plastic and other raw materials after melting and stored in the feeding box 2 to move upwards along the mixing bin, avoiding the long-term accumulation of the modified plastic and other raw materials after melting. At the same time, the modified plastic and other raw materials after melting will also be dispersed after passing through the small holes in the inside of the scraper 207, avoiding the long-term mixing of the same modified plastic raw materials or other raw materials, and further improving the mixing uniformity of the modified plastic and other raw materials;

[0037] After the modified plastic and other raw materials after melting move upwards along the mixing bin, they will enter the feed inlet in the inside of the guide plate 201. At the same time, the top servo motor 202 will rotate the stirring blade 204 through the connecting shaft 203, so that the modified plastic and other raw materials after melting moving upwards will collide with the rotating stirring blade 204 in the feed inlet. After that, these modified plastic and other raw materials after melting will drop again due to gravity and contact with the scraper 207, so that the modified plastic and other raw materials after melting repeatedly rise and fall in the feeding box 2, further improving the mixing uniformity of the modified plastic and other raw materials;

[0038] The bottom end inside of the feeding box 2 is embedded with a discharge pipe, the middle part of the discharge pipe is provided with an electric control valve, and the bottom end of the discharge pipe is embedded above the middle part of the granulating cylinder 102;

[0039] After the electric control valve is opened, the raw materials after melting will enter the middle part of the granulating cylinder 102 along the pipeline.

[0040] Example 2, please refer to Figures 1-7 , the difference between example 2 and example 1 is that the granulating assembly is composed of a fixed rod 303, a partition plate 304, a top pressing plate 305, a limiting plate 306, a cooling cylinder 307, a separation pipe 308, a cutting motor 309 and a cutting blade 310;

[0041] The middle part of the granulation cylinder 102 is embedded with a fixed rod 303, the outer wall of the fixed rod 303 is fixed with a partition plate 304, the inside left side of the granulation cylinder 102 is embedded with a pressing plate 305, the left side of the granulation cylinder 102 is fixed with a limiting plate 306, the right side of the granulation cylinder 102 is fixed with a cooling cylinder 307, the inside of the cooling cylinder 307 is transversely fixed with a separation pipe 308, the right side of the separation pipe 308 is fixed with a cutting motor 309 through an outer cover, and the transmission shaft outer wall of the output end of the cutting motor 309 is fixed with a cutting blade 310;

[0042] The right side of the push rod output by the hydraulic cylinder 3 is fixed with a top plate 301, the right side of the top plate 301 and the right side of the limiting plate 306 are close to the left side of the pressing plate 305, and the inside right side of the top plate 301 and the inside right side of the limiting plate 306 are provided with magnetic blocks which are mutually attracted by the magnetic force generated by the left side of the pressing plate 305;

[0043] When the molten raw material enters between adjacent partition plates 304, the hydraulic cylinder 3 pushes the pressing plate 305 to move right between adjacent partition plates 304 by pushing the top plate 301, so that the pressing plate 305 extrudes the molten raw material, and the molten raw material enters the separation pipe 308 of the cooling cylinder 307 to be cooled and formed;

[0044] After granulation, because the right side of the top plate 301 and the left side of the pressing plate 305 are mutually attracted by the magnetic force, the hydraulic cylinder 3 can pull the pressing plate 305 to move left between adjacent partition plates 304 by pulling the top plate 301, and when the right side of the limiting plate 306 is close to the pressing plate 305, the limiting plate 306 will limit the pressing plate 305 to avoid moving out of the left side of the granulation cylinder 102, when the top plate 301 extends out of the left side of the granulation cylinder 102, the three-phase motor 302 can normally drive the fixed rod 303 and the partition plate 304 on the fixed rod 303 to rotate, at this time the right side of the limiting plate 306 will generate a magnetic force to tightly attract the pressing plate 305, avoiding the pressing plate 305 to slide left and right in the granulation cylinder 102 at will;

[0045] Three partition plates 304 are equidistantly arranged on the outside of the fixed rod 303, and the pressing plate 305 is embedded between adjacent partition plates 304, and the middle part of the pressing plate 305 and the middle part of the top plate 301 are on the same horizontal plane;

[0046] The main function of the top plate 301 is to push the pressing plate 305 to slide left and right between adjacent partition plates 304, and pull the pressing plate 305 to restore to the original position;

[0047] The fixed rod 303 and the partition plate 304 rotate forward and backward by 120° in the granulation cylinder 102, so that the pressing plate 305 which restores to the original position each time is just located at the right side of the top plate 301;

[0048] A plurality of separation pipes 308 with different diameters are arranged above the inner top, the front end of the inner bottom and the rear end of the inner bottom of the cooling cylinder 307, and each group of separation pipes 308 is in the same horizontal plane as the middle part of the top pressing plate 305.

[0049] After the raw material is melted and stored between the uppermost adjacent baffles 304, the three-phase motor 302 can drive the baffles 304 to rotate 120° clockwise or counterclockwise in the granulating cylinder 102 through the fixed rod 303, so that the three adjacent baffles 304 store an appropriate amount of melted raw material.

[0050] Since the separation pipes with the same horizontal position and different diameters are arranged just to the right of the top pressing plate 305, when the hydraulic cylinder 3 pushes the melted raw material to the right through the separation pipes 308 by the top plate 301, the cold water stored in the cooling cylinder 307 can cool the raw material through the separation pipes 308, so that the raw material pipes with three different diameters can be stretched out from the right side of the separation pipes 308, so that the cutting blade 301 can cut the stretched raw material pipes into three different sizes.

[0051] The particle size can be adjusted according to actual conditions, and when two or one portion of the melted raw material is stored between the three baffles 304, the granulation of two or one kind of different size particles can also be realized, and multiple batches of granulation can be realized without repeated replacement of molds, which is more time-saving and labor-saving.

[0052] For example 3, please refer to Figures 1-7 , the difference between example 3 and example 2 is that the left side of the separation pipe 308 is in communication with the right side of the granulating cylinder 102, the right side of the separation pipe 308 is stretched out from the right side of the cooling cylinder 307, the right side of the cooling cylinder 307 and the right side of the separation pipe 308 are in the same vertical plane, the left side of the cutting blade 310 is close to the right side of the separation pipe 308, and the upper and lower ends of the cooling cylinder 307 are respectively provided with water inlet and outlet;

[0053] The cooling water can be injected into the cooling cylinder 307 through the water outlet, so that when the melted raw material enters the separation pipe 308, the cooling water can absorb the heat of the separation pipe 308 to cool the raw material entering the separation pipe 308, so that the cooled raw material can be quickly formed;

[0054] After the tubular raw material is cooled and formed, the cutting motor 309 drives the cutting blade 310 to rotate, so that the cutting blade 310 cuts the stretched raw material, and the tubular raw material is in the form of particles and falls along the outer cover of the right side of the cooling cylinder 307.

[0055] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the concept of the present application, can also be made several variations and improvements, these should also be considered as the protection scope of the present application, these will not affect the effect and the practicality of the patent of the present application.
