Description

Technical Field

[0001] This invention relates to the field of plastic particle production technology, specifically to a plastic particle granulation device. Background Technology

[0002] Plastic pellets, also known as plastic granules, are raw materials used for storing, transporting, and processing plastics in a semi-finished form. Plastics are a type of polymer material, made from petroleum as a raw material, which can produce ethylene, propylene, vinyl chloride, styrene, etc. Under certain conditions, the molecules of these substances can react with each other to form compounds with very large molecular weights, i.e., polymers.

[0003] Currently, some plastic particles are produced by extruding them using a plastic extruder. A cutting device is then installed at the outlet of the plastic extruder to cut the continuously extruded plastic into small plastic particles. These particles fall into a collection box for collection. However, the plastic particles falling directly into the collection box not only have a short falling time, resulting in reduced cooling effect, but also tend to accumulate, making it difficult for the material below to cool down. Furthermore, the temperature of the plastic particles that fall first differs from that of the particles that fall later, causing the material to require more time to cool down. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a granulation device for plastic particles, which solves the problems of plastic particles falling directly into the collection box, resulting in a short falling time and reduced cooling effect, as well as the tendency of plastic particles to accumulate, making it difficult to cool the material below, and the different cooling degrees of plastic particles that fall first and later, causing the material to take longer to cool.

Two symmetrically arranged fixed gantry frames are slidably connected to the upper surface of the worktable. The top of the fixed gantry is fixedly connected to an upper mounting base, and the top of the upper mounting base is fixedly connected to a cold water tank. A first water pumping assembly is installed on one side of the cold water tank, and a second water pumping assembly is installed on the other side of the cold water tank.

[0008] Preferably, the first rotary connecting shaft has two symmetrically arranged limiting strips fixedly connected inside, and the outer surface of the inner movable slide rod has two symmetrically arranged limiting grooves. The limiting strips are slidably connected inside the corresponding limiting grooves.

[0009] Preferably, the first linkage component includes a first pulley fixedly connected to the end of the first rotary connecting shaft, and a second pulley fixedly connected to the end of the fixed shaft, wherein the first pulley and the second pulley are connected by a first belt drive.

[0010] Preferably, the second linkage component includes a third pulley fixedly connected to the outer surface of the fixed shaft, and a fourth pulley fixedly connected to the end of the second rotary connecting shaft. The third pulley and the fourth pulley are connected by a second belt drive.

[0011] Preferably, the meshing speed regulating component includes a first driving gear, a second driving gear, a third driving gear, a first linkage gear, a second linkage gear, and a third linkage gear.

The first driving gear meshes with the first linkage gear, the second driving gear is adapted to the second linkage gear, and the third driving gear is adapted to the third linkage gear. When the first driving cylinder is activated, the piston end of the first driving cylinder moves with the mounting rectangular plate, and the mounting rectangular plate moves with the fourth rotary connecting shaft, causing the second driving gear and the second linkage gear to mesh, thereby increasing the speed of the rotating fan blades for the first time.

The cold water flows out through the multiple drainage holes at the bottom of the water pipe, allowing it to enter the first lower water housing. After passing through the first lower water housing, it forms a water curtain that flows down into the second lower water housing.

[0016] (III) Beneficial Effects

[0017] This invention provides a granulation device for plastic particles. It has the following beneficial effects:

[0018] 1. In this invention, the first driving cylinder is activated, and the piston end of the first driving cylinder moves the mounting rectangular plate. The mounting rectangular plate moves the fourth rotating connecting shaft, causing the second driving gear to mesh with the second linkage gear. This provides an initial speed increase to the rotating fan blades, altering the falling trajectory of the plastic particles. This not only increases the falling time of the plastic particles but also changes their falling position, preventing them from accumulating together. Simultaneously, because the later-falling plastic particles have a longer contact time with the cold air, the temperature difference between the earlier and later-falling plastic particles is smaller, shortening the cooling time and improving efficiency.

[0019] 2. In this invention, the second water pump is started, drawing cold water from inside the cold water tank into the second connecting pipe. The cold water flows out through multiple drainage holes at the bottom of the water pipe, allowing it to enter the first lower water housing. After passing through the first lower water housing, it forms a water curtain that flows down into the second lower water housing. Simultaneously, the first water pump is started to draw heat-absorbing water into the cold water tank. The second drive cylinder is started, and the piston end of the second drive cylinder moves the fixed gantry, causing the first and second lower water housings to move. This allows for easy adjustment of the positions of the first and second lower water housings, facilitating the absorption of heat at different locations.

[0020] 3. In this invention, the fixed shaft rotates the second rotating connecting shaft via the second linkage assembly, the second rotating connecting shaft rotates the fourth rotating connecting shaft via the meshing speed regulating assembly, the fourth rotating connecting shaft rotates the third rotating connecting shaft, the third rotating connecting shaft rotates the fifth rotating connecting shaft via the third linkage assembly, and the fifth rotating connecting shaft rotates the rotating fan blades. When the rotating fan blades rotate and blow air, they blow the plastic particles falling from above, causing the plastic particles to fall in a parabolic trajectory instead of falling in a straight line, thus increasing the time for the plastic particles to fall and prolonging the contact time between the plastic particles and the cold air.

[0021] 4. In this invention, plastic is extruded through a plastic extruder and then exits through the discharge port. A servo motor is started, and the output shaft of the servo motor rotates the fixed shaft, causing the first rotating connecting shaft to rotate. The first rotating connecting shaft rotates the inner movable slide rod, which in turn rotates the fixed round block. The fixed round block then rotates the rotating cutting blade, causing the rotating cutting blade to cut the plastic into individual plastic particles. By loosening the fixing bolts, the inner movable slide rod can slide inside the first rotating connecting shaft, thereby adjusting the position of the rotating cutting blade and facilitating the adjustment of the size of the cut plastic particles.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-7 As shown, this embodiment of the invention provides a granulation device for plastic particles, including a workbench 1. An equipment mounting platform 2 is fixedly connected to the upper surface of the workbench 1. A plastic extruder 3 is fixedly mounted on the top of the equipment mounting platform 2. A discharge port is provided on one side of the plastic extruder 3. An L-shaped mounting bracket 4 is fixedly connected to one side of the equipment mounting platform 2. A first rotary connecting shaft 5 is rotatably connected through and to the side wall of the L-shaped mounting bracket 4. An inner movable slide rod 6 is slidably connected inside the first rotary connecting shaft 5. Two symmetrically arranged limiting strips 8 are fixedly connected inside the first rotary connecting shaft 5. Two symmetrically arranged limiting grooves 9 are formed on the outer surface of the inner movable slide rod 6. The limiting strips 8 are slidably connected inside the corresponding limiting grooves 9. A fixing bolt 7 is threadedly connected to the outer surface of the first rotary connecting shaft 5. The end of the fixing bolt 7 extends to the first rotary connecting shaft 5. The inner side of the connecting shaft 5 abuts against the outer surface of the inner movable slide rod 6. The end of the inner movable slide rod 6 is fixedly connected to a fixed round block 10. The outer surface of the fixed round block 10 is fixedly connected to a rotary cutting blade 11. Plastic is extruded by the plastic extruder 3 and then comes out through the discharge port. The servo motor 12 is started. The output shaft of the servo motor 12 rotates the fixed shaft, causing the first rotary connecting shaft 5 to rotate. The first rotary connecting shaft 5 rotates the inner movable slide rod 6, which in turn rotates the fixed round block 10. The fixed round block 10 rotates the rotary cutting blade 11, causing the rotary cutting blade 11 to cut the plastic into plastic particles. By loosening the fixing bolt 7, the inner movable slide rod 6 can slide inside the first rotary connecting shaft 5, thereby adjusting the position of the rotary cutting blade 11 and making it easier to adjust the size of the cut plastic particles.

[0033] A servo motor 12 is fixedly connected to the side wall of the L-shaped mounting bracket 4. The output shaft of the servo motor 12 is fixedly connected to a fixed shaft. A first linkage assembly is provided between the fixed shaft and the first rotary connecting shaft 5. The first linkage assembly includes a first pulley fixedly connected to the end of the first rotary connecting shaft 5 and a second pulley fixedly connected to the end of the fixed shaft. The first pulley and the second pulley are connected by a first belt drive.

[0034] The side wall of the equipment mounting platform 2 is rotatably connected to a second rotary connecting shaft 13 and a third rotary connecting shaft 14. A second linkage assembly is provided between the second rotary connecting shaft 13 and the fixed shaft. The second linkage assembly includes a third pulley fixedly connected to the outer surface of the fixed shaft. A fourth pulley is fixedly connected to the end of the second rotary connecting shaft 13. The third pulley and the fourth pulley are connected by a second belt drive.

[0035] A fixed outer sleeve rod 15 is fixedly connected to the end of the third rotary connecting shaft 14. A movable inner moving rod 16 is slidably connected inside the fixed outer sleeve rod 15. A fourth rotary connecting shaft 17 is fixedly connected to the end of the movable inner moving rod 16 away from the fixed outer sleeve rod 15. A meshing speed regulating component is provided between the second rotary connecting shaft 13 and the fourth rotary connecting shaft 17. The meshing speed regulating component includes a first driving gear 20, a second driving gear 21, a third driving gear 22, a first linkage gear 23, a second linkage gear 24, and a third linkage gear 25. The first driving gear 20, the second driving gear 21, and the third driving gear 22 are all fixedly connected to the outer surface of the second rotary connecting shaft 13. The first linkage gear 23, the second linkage gear 24, and the third linkage gear 25 are all fixedly connected to the outer surface of the fourth rotary connecting shaft 17. The first driving gear 20 and the first linkage gear 23 are meshed together. The second driving gear 21 and the second linkage gear 24 are matched together. The third driving gear 22 and the third linkage gear 25 are matched together.

[0036] A power assembly for driving the fourth rotary connecting shaft 17 to move is installed on the upper surface of the workbench 1. The power assembly includes a first drive cylinder 18 fixedly connected to the upper surface of the workbench 1. A mounting rectangular plate 19 is fixedly connected to the piston end of the first drive cylinder 18. The side wall of the mounting rectangular plate 19 is rotatably connected to one end of the fourth rotary connecting shaft 17. The fixed shaft drives the second rotary connecting shaft 13 to rotate through the second linkage assembly. The second rotary connecting shaft 13 drives the fourth rotary connecting shaft 17 to rotate through the meshing speed regulating assembly. The fourth rotary connecting shaft 17 drives the third rotary connecting shaft 14 to rotate. The third rotary connecting shaft 14 drives the fifth rotary connecting shaft to rotate through the third linkage assembly. The fifth rotary connecting shaft drives the rotating fan blade 26 to rotate. When the rotating fan blade 26 rotates and blows air, it blows the plastic particles falling from above, causing the plastic particles to fall in a parabola instead of falling in a straight line, increasing the time for the plastic particles to fall and prolonging the contact time between the plastic particles and the cold air.

[0037] The L-shaped mounting bracket 4 is rotatably connected to a fifth rotary connecting shaft on the side away from the servo motor 12. A rotary fan blade 26 is fixedly connected to the end of the fifth rotary connecting shaft. A third linkage assembly is provided between the third rotary connecting shaft 14 and the fifth rotary connecting shaft. The third linkage assembly includes a fifth pulley fixedly connected to the end of the third rotary connecting shaft 14, and a sixth pulley fixedly connected to the outer surface of the fifth rotary connecting shaft. The fifth pulley and the sixth pulley are connected via a third belt drive. When the first drive cylinder 18 is activated, the piston end of the first drive cylinder 18 moves the mounting rectangular plate 19, which in turn moves the fourth rotary fan blade 26. The movement of the connecting shaft 17 causes the second drive gear 21 to mesh with the second linkage gear 24, thereby increasing the speed of the rotating fan blade 26 for the first time. This changes the falling trajectory of the plastic particles, increasing not only the falling time but also the falling position, preventing the plastic particles from piling up. At the same time, because the later falling plastic particles have a longer contact time with the cold air, the temperature difference between the falling and earlier falling plastic particles is smaller, shortening the cooling time and improving efficiency. By meshing the third drive gear 22 with the third linkage gear 25, the rotating fan blade 26 can be increased in speed for the second time.

[0038] A particle collection box 39 is placed on the upper surface of the workbench 1. The particle collection box 39 is located below the side of the rotating blower blade 26. Two symmetrically arranged fixed gantry frames 27 are slidably connected to the upper surface of the workbench 1. An upper mounting base 29 is fixedly connected to the top of the fixed gantry frame 27. A cold water tank 30 is fixedly connected to the top of the upper mounting base 29. A first water pumping assembly is installed on one side of the cold water tank 30. The first water pumping assembly includes a first water pump 31 fixedly connected to the side wall of the cold water tank 30. A first connecting pipe 32 is fixedly connected to the inlet of the first water pump 31. The end of the first connecting pipe 32 away from the first water pump 31 is fixedly connected to the second lower water housing 38.

[0039] A refrigeration device is installed on the cold water tank 30 to cool the water inside the cold water tank 30. A second water pumping assembly is installed on the other side of the cold water tank 30. The second water pumping assembly includes a second water pump 33 fixedly connected to the side wall of the cold water tank 30. A second connecting pipe 34 is fixedly connected to the outlet of the second water pump 33. A water flow pipe 35 is fixedly connected to the end of the second connecting pipe 34 away from the second water pump 33. Multiple water leakage holes are opened at the bottom of the water flow pipe 35. The water flow pipe 35 is located above the first water outlet housing 36.

[0040] A first lower water housing 36 is fixedly connected between the opposite sides of two fixed gantry frames 27. Connecting rods 37 are fixedly connected to both sides of the first lower water housing. A second lower water housing 38 is fixedly connected between the opposite sides of the two connecting rods 37. A second drive cylinder 28 is fixedly connected to the upper surface of the workbench 1. The piston end of the second drive cylinder 28 is fixedly connected to the corresponding side of the fixed gantry frame 27. When the second water pump 33 is started, it draws cold water from the cold water tank 30 into the second connecting pipe 34. The cold water then flows through the water pipe... Multiple drainage holes at the bottom of 35 allow cold water to flow into the first lower water housing 36. After passing through the first lower water housing 36, the water forms a water curtain and flows down into the second lower water housing 38. At the same time, the first water pump 31 is activated to draw the heat-absorbing water into the cold water tank 30. The second drive cylinder 28 is activated, and the piston end of the second drive cylinder 28 moves the fixed gantry 27, causing the first lower water housing 36 and the second lower water housing 38 to move. This allows for easy adjustment of the positions of the first lower water housing 36 and the second lower water housing 38, enabling the absorption of heat at different locations.

[0041] Working principle:

[0042] In use, plastic is extruded through the plastic extruder 3 and then comes out through the discharge port. The servo motor 12 is started, and the output shaft of the servo motor 12 rotates the fixed shaft, causing the first rotating connecting shaft 5 to rotate. The first rotating connecting shaft 5 rotates the inner movable slide rod 6, which in turn rotates the fixed round block 10. The fixed round block 10 rotates the rotating cutting blade 11, causing the rotating cutting blade 11 to cut the plastic into individual plastic particles. By loosening the fixing bolt 7, the inner movable slide rod 6 can slide inside the first rotating connecting shaft 5, thereby adjusting the position of the rotating cutting blade 11 and making it easier to adjust the size of the cut plastic particles.

[0043] Meanwhile, the fixed shaft rotates the second rotating connecting shaft 13 via the second linkage component, the second rotating connecting shaft 13 rotates the fourth rotating connecting shaft 17 via the meshing speed regulating component, the fourth rotating connecting shaft 17 rotates the third rotating connecting shaft 14, the third rotating connecting shaft 14 rotates the fifth rotating connecting shaft via the third linkage component, and the fifth rotating connecting shaft rotates the rotating fan blade 26. When the rotating fan blade 26 rotates and blows air, it blows the plastic particles falling from above, causing the plastic particles to fall in a parabolic arc instead of falling in a straight line, thus increasing the time for the plastic particles to fall and prolonging the contact time between the plastic particles and the cold air.

[0044] The first drive cylinder 18 is activated, and the piston end of the first drive cylinder 18 moves the mounting rectangular plate 19. The mounting rectangular plate 19 moves the fourth rotating connecting shaft 17, causing the second drive gear 21 to mesh with the second linkage gear 24, thereby accelerating the rotating fan blade 26 for the first time. This changes the falling trajectory of the plastic particles, increasing not only the falling time of the plastic particles but also changing their falling position, preventing them from accumulating together. At the same time, because the plastic particles that fall later have a longer contact time with the cold air, the temperature difference between the plastic particles falling earlier and later is smaller, shortening the cooling time and improving efficiency. By meshing the third drive gear 22 with the third linkage gear 25, the rotating fan blade 26 can be accelerated for the second time.

[0045] The second water pump 33 is started, drawing cold water from the cold water tank 30 into the second connecting pipe 34. The cold water flows out through multiple drainage holes at the bottom of the water pipe 35, allowing it to enter the first lower water housing 36. After passing through the first lower water housing 36, it forms a water curtain and flows down into the second lower water housing 38. At the same time, the first water pump 31 is started to draw heat-absorbing water into the cold water tank 30. The second drive cylinder 28 is started, and the piston end of the second drive cylinder 28 moves the fixed gantry 27, causing the first lower water housing 36 and the second lower water housing 38 to move, facilitating the adjustment of their positions and allowing for the absorption of heat at different locations.
