Description

Technical Field

[0001] The invention relates to the technical field of plastic masterbatch granulation, in particular to a plastic masterbatch granulation device. Background Art

[0002] Plastic masterbatch granulation refers to the process of mixing high-concentration pigments with resin carriers and other additives to make granular products through a specific process. It is usually used for coloring plastic products. The plastic masterbatch granulation process usually involves melting and mixing the precisely weighed ingredients, then feeding them into the die head of the extruder, and extruding them through tiny pores under high pressure to form long strips. When the material cools and has a certain hardness, it is cut into small particles by a pelletizer.

[0003] In the current plastic masterbatch pelletizing process, the pelletizer is usually located at the end of the extruder, which can cut the extruded long strips into particles of uniform size. The air-cooled pelletizer uses a fan to cool the extruded melt strip before pelletizing. It does not require water cooling and will not produce sewage, which is beneficial to saving resources. However, the temperature of the plastic is too high after extrusion, and the air-cooled pelletizer is prone to pelletizing before the plastic is completely cooled, resulting in knife sticking. Secondly, the pelletizer is usually equipped with a single set of cutters. When replacing the worn cutter and cleaning the cutter, the pelletizer needs to stop operating, affecting the efficiency of pelletizing. Furthermore, when cleaning the cutter, the plastic stuck to the outer wall of the cutter is difficult to clean after cooling, and it is not convenient to peel off the plastic on the outer wall of the cutter.

[0042] Reference Figure 3 , Figure 7 and Figure 8 The right part of the bidirectional screw rod 52 is threadedly connected to a connecting seat three 55, and the connecting seat three 55 is composed of a plate and a plurality of cross bars fixed along the circumferential direction of the annular member of the connecting seat two 54 on the left wall of the plate. Holes matching the cross bars of the connecting seat three 55 are opened on the two circular plates of the support member 32. The annular member of the connecting seat two 54 and the cross bars of the connecting seat three 55 are both provided with disassembly and assembly components two 56, and the disassembly and assembly components two 56 include support rods 561.

[0044] The plastic strip is extruded through the extrusion port of the extrusion device 2, and the output end of the motor 2 33 located below the extrusion device 2 drives the rotating seat 34 to rotate counterclockwise, and the disassembly part 411, the knife seat 412 and the blade 413 rotate counterclockwise accordingly. The blade 413 is inclined at a certain angle to the right side wall of the extrusion device 2, and the rotating blade 413 performs a rotary cutting operation.

[0045] The air cooler 421 blows out cold air through a branch outlet 1 of a ventilation duct 422, and the cold air blows toward the blade surface of the blade 413 and then toward the cutting plastic strip, so that the cold air can be positioned locally for accurate and rapid cooling, thereby reducing the sticking of the knife during the cutting process. At this time, the sealing member 423 is close to the branch outlet 2 of the ventilation duct 422, blocking the cold air from blowing out from the branch outlet.

[0046] After a period of time, the output end of the motor 31 drives the support member 32 to rotate, and the support member 32 drives the two sets of rotary pelletizing mechanisms 4 to switch positions, and the two sets of blades 413 perform alternate rotary cutting operations, which is convenient for improving the efficiency of the rotary cutting operation. The rotary pelletizing mechanism 4 rotated to the top of the extrusion device 2 can be disassembled, repaired and cleaned.

[0047] During disassembly and maintenance, the positioning bolt 418 is pulled out of the hole that matches the ring of the matching piece 417 and the rotating seat 34, and the ring of the matching piece 417 is rotated to drive the wedge block of the matching piece 417 to move until the wedge block of the matching piece 417 moves to the lower end of the adjusting piece 415 and pushes the adjusting piece 415 to move away from the rotating seat 34. The adjusting piece 415 drives the T-block of the limiting piece 414 to slide from the inside to the outside on the rotating seat 34, and the spring connected to the T-block of the limiting piece 414 is compressed, and the wedge block of the limiting piece 414 moves away from the groove on the arrow piece, releasing the limit on the arrow piece, and the spring connected to the stop piece 416 drives the stop piece 416 to rebound a certain distance The disassembly part 411 is pushed to the left to help the square block of the disassembly part 411 to separate from the inner wall of the rotating seat 34, so that the disassembly part 411 can be manually pulled out as a whole to realize the disassembly of the knife seat 412 and the blade 413; when installing the disassembly part 411, the disassembly part 411 is directly inserted into the rotating seat 34, and the arrow part pushes the wedge block of the limiting part 414 to move from the inside to the outside, and the insertion is continued until the wedge block of the limiting part 414 is separated from the inclined outer wall of the arrow part, and is moved down to the groove of the arrow part by the corresponding spring force, and the disassembly part 411 is limited by multiple limiting parts 414, and the square block of the disassembly part 411 is engaged with the rotating seat 34 to realize quick disassembly and assembly.

[0048] Before cleaning, the cold air machine 421 is turned off, and the bottom output end of the electric push rod 427 moves downward to drive the adjusting block 424 to approach the sealing piece 423 located above the extrusion device 2. The bottom wall of the adjusting block 424 gradually enters the adapting groove of the sealing piece 423 and pushes the sealing piece 423 away from the branch outlet 2 of the ventilation duct 422. Then the air outlet of the hot air machine 426 is downwardly aligned with the branch outlet 2 of the ventilation duct 422 and hot air is introduced. The hot air is blown toward the blade surface of the blade 413 through the ventilation duct 422, so that the hot air can be positioned locally for accurate and rapid heating, so that the plastic adhered to the outer wall of the blade 413 is softened by the heat, which plays an auxiliary role in the subsequent cleaning work. It should be noted that a one-way valve can be set at the air outlet of the cold air machine 421 to prevent hot air from entering and damaging its internal structure.

[0049] During cleaning, the output end of motor three 51 drives the bidirectional screw rod 52 to rotate, and the collecting piece 53 and the connecting seat three 55 both approach the rotating pelletizing mechanism 4. The collecting box of the collecting piece 53 slides to the bottom of the rotating pelletizing mechanism 4 to collect the debris dropped during cleaning. The cross bar of the connecting seat three 55 drives the corresponding disassembly and assembly component two 56 to move to the right side wall close to the blade 413, and the connecting seat two 54 drives the disassembly and assembly component two 56 to move to the left side wall of the blade 413. A sponge cover (not shown in the figure) is installed on the outer wall of the support rod 561. The motor two 33 drives the blade 413 to rotate. Through the friction between the blade 413 and the sponge cover, the softened plastic on both sides of the blade 413 is cleaned at the same time.

[0050] When disassembling the sponge cover after long-term cleaning, remove the gasket 565 engaged on the outer wall of the end of the adjusting rod 562. The adjusting rod 562 is rebounded by the spring, driving the adjusting part 2 563 to move and away from the matching part 2 564. After the matching part 2 564 loses the pushing effect of the adjusting part 2 563, it slides from the outside to the inside under the rebound effect of the corresponding spring, releasing the support for the sponge cover. The resistance of the smooth outer wall of the sponge cover and the support rod 561 is small, which makes it easy to quickly peel the sponge cover from the support rod 561, thereby realizing the rapid disassembly and replacement of the sponge cover.

[0051] Reference Figure 1 , Fig. 9 and Fig.11 The shaping mechanism 6 includes a shaping barrel 61, which is composed of a left barrel body, a right barrel body and a connecting rod fixedly connected between the left barrel body and the right barrel body. The inner wall of the processing chamber of the support seat 1 is rotatably connected with the shaping barrel 61. The outer wall of the shaping barrel 61 is evenly arranged with multiple groups of sieve holes. A feeder 62 is rotatably connected between the left barrel body and the right barrel body of the shaping barrel 61. The feeder 62 is composed of a cylinder connected to a ring and a top wall of the ring and a collecting bucket of the support seat 1. The bottom inner wall of the ring of the feeder 62 is a left-right symmetrical inclined surface. The side wall of the shaping barrel 61 is fixedly connected with a feeder 62. Part 62 is a driving part 63 that is symmetrically distributed around the center. The outer wall of the shaping barrel 61 is rotatably connected to a feeding part 64 that is symmetrically distributed around the feeding part 62. The feeding part 64 is composed of a cylinder connected to a circular ring and a bottom wall of the circular ring. The inner walls of the left and right barrel bodies of the shaping barrel 61 are inclined toward the cylinder of the feeding part 64. Two groups of guide parts that are symmetrical on the left and right are arranged on the connecting rod. The guide parts are composed of a plurality of guide blocks that are evenly distributed along the circumference of the connecting rod. The upper side of the upper guide block is inclined toward the cylinder of the feeding part 64. Reinforcing rods are connected between the guide part and the left barrel body as well as between the guide part and the right barrel body.

[0052] Reference Figure 1 , Fig. 9 and Fig.10 The auxiliary cooling mechanism 7 includes a second air cooler 71. The middle side wall of the support seat 1 is equipped with the second air cooler 71. The second air cooler 71 is connected to two air outlets 1 73 and two air outlets 2 74 through a ventilation duct 2 72. The two air outlets 1 73 are arranged on the front and rear sides of the extrusion device 2, and the two air outlets 2 74 are arranged at the rear of the shaping barrel 61 and correspond one to one with the driving member 63.

[0053] The cold air from the second air cooler 71 is blown out through the ventilation duct 2 72, the air outlet 1 73 and the second air outlet 74. On both sides of the extruder 2 during the peeling process, the cold air blown out through the air outlet 1 73 is cooled in a large area to help cool the cut plastic strips; the driving member 63 is blown through the air outlet 2 74 to drive the shaping barrel 61 to rotate slowly, and the peeled plastic masterbatch falls into the collecting bucket of the support seat 1, and falls into the shaping barrel 61 through the feeding member 62. Some of the plastic masterbatch concentrated between the left barrel body and the right barrel body of the shaping barrel 61 is guided by the guide member and falls to the left and right, and the other part has been The plastic masterbatch that falls to the bottom of the circular ring of the feeding piece 62 is divided and falls to the left and right at the top wall of the inclined surface of the bottom circular ring of the feeding piece 62, so that the particles dropped from the middle of the shaping barrel 61 are more evenly distributed in the shaping barrel 61. The rotating shaping barrel 61 drives the plastic masterbatch inside to roll, which plays a certain shaping role, making the shape of the plastic masterbatch more uniform. At the same time, the broken and unqualified plastic masterbatch falls out through the sieve holes of the shaping barrel 61, and the qualified plastic masterbatch moves to the lower feeding piece 64 through the inclined inner wall inside the shaping barrel 61, and the qualified products are discharged from the bottom of the lower feeding piece 64.

[0054] The specific operation steps of the plastic masterbatch granulating device are as follows: first, the extrusion port of the extrusion device 2 extrudes plastic strips, the motor 2 33 drives the blade 413 to perform rotary cutting, and the air cooler 421 blows out cold air through the branch port of the ventilation duct 422. The cold air blows to the blade 413 to cut the part of the plastic strip to accelerate cooling. At the same time, the cold air blown out by the air cooler 2 71 cools the extrusion device 2 through the air outlet 1 73. The two groups of blades 413 are driven by the support member 32 to perform alternating rotary cutting operations to improve processing efficiency. During alternating operations, the blades 413 that are not performing rotary cutting can be cleaned and disassembled, and the wind blown out by the air outlet 2 74 drives the driving member 63 to drive the shaping barrel 61 to rotate, driving the plastic masterbatch inside the shaping barrel 61 to be shaped and screened through the shaping barrel 61.

[0055] Hot air is blown into the ventilation duct 1 422 by the hot air blower 426, and the hot air blows toward the blade surface of the blade 413, so that the plastic adhered to the surface of the blade 413 softens, and then the motor 3 51 drives the collecting member 53, the connecting seat 2 54 and the connecting seat 3 55 to move, and the collecting member 53 collects the debris dropped during cleaning, and the connecting seat 2 54 and the connecting seat 3 55 drive the disassembly assembly 2 56 to move to the cleaning position, and the self-rotation of the blade 413 and the sponge cover provided on the outer surface of the disassembly assembly 2 56 generate friction, so as to wipe off the plastic on the surface of the blade 413. When the sponge cover that needs to be used for a long time is replaced, the gasket 565 is removed, and the matching member 2 564 releases the support for the inner wall of the sponge cover, so that the sponge cover can be quickly removed for replacement.
