Description

Technical Field

[0001] This utility model belongs to the field of plastic pelletizing technology, and in particular relates to a modified plastic pelletizing device. Background Technology

[0002] Modified plastic granules are plastic granules obtained by altering the original properties of general-purpose or engineering plastics through physical and chemical methods. Compared with ordinary plastic granules, they have superior performance. For example, in terms of heat resistance, by adding special modifiers, modified plastic granules can withstand higher temperatures, which makes them suitable for applications in high-temperature environments, such as parts near automobile engines. In terms of mechanical properties, their strength and toughness can be adjusted according to specific needs to meet different usage scenarios.

[0003] Modified plastic pellet preparation and pelletizing equipment is a key piece of equipment in the plastic processing process. It is mainly used to cut modified plastic strips or filaments into uniform plastic pellets to facilitate subsequent packaging, transportation and reprocessing.

[0004] Currently, existing technologies have the problem that if the pelletizing device cannot change the blade quickly, it will have to shut down for a long time when the blade wears out and needs to be replaced. In the process of continuous production of modified plastic pellets, the blade may become dull because it has cut a certain amount of plastic strips. If the blade changing process is complicated and time-consuming, each blade changing may take several hours. This will cause frequent interruptions to the entire production process. For large-scale production enterprises, long-term equipment downtime means a significant drop in output.

[0005] To address the aforementioned issues, this application proposes a modified plastic pellet preparation and pelletizing apparatus. Utility Model Content

[0006] The purpose of this invention is to provide a modified plastic granule preparation and pelletizing device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a modified plastic granulation and pelletizing device, comprising a housing, a discharge shell fixedly connected to the bottom surface of the housing, a feed shell fixedly connected to the back surface of the housing, a rotary motor and a controller respectively disposed on the front surface of the housing, two slotted frames fixedly connected to the inner wall of the housing, two sliding frames slidably connected to the interior of the two slotted frames, a rotary bearing fixedly connected to the inner wall of each sliding frame, two connecting rods and two blade holders respectively disposed inside the housing, the outer surface of each connecting rod being fixedly connected to the inner wall of the inner ring of the rotary bearing, a connecting frame fixedly connected to the end of each connecting rod near the rotary bearing, a connecting block slidably connected to the interior of one of the connecting frames, and two threaded pins threadedly connected to the inner walls of one of the connecting frames and the connecting block, and the output end of the rotary motor being fixedly connected to the front surface of the connecting block.

[0009] Furthermore, both sides of the housing are movably hinged with opening and closing doors, and each of the two opening and closing doors is fixedly connected to a handle on the side that is far apart from each other.

[0010] Furthermore, a support plate is fixedly connected to the bottom surface of the controller, and the back side of the support plate is fixedly connected to the front side of the housing.

[0011] Furthermore, a fixing frame is fixedly connected to the bottom surface of the rotary motor, and the back side of the fixing frame is fixedly connected to the front side of the housing.

[0012] Furthermore, a protective shell is fixedly connected to the outer surface of the fixed frame, and two sets of ventilation openings are provided on the front of the protective shell. The protective shell is fitted over the outside of the rotary motor.

[0013] Furthermore, each of the connecting rods has a limit frame rotatably connected to its outer surface, and the front of each limit frame is fixedly connected to the back of the sliding frame.

[0014] Furthermore, a connecting ring is fixedly connected to the inner wall of each tool holder, and the inner wall of each connecting ring is fixedly connected to the outer surface of the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] This utility model uses a rotary motor to rotate a connecting block. The connecting block is connected to a connecting frame via a threaded pin, which in turn causes the connecting frame and connecting rod to rotate within a rotating bearing and a sliding frame. The rotation of the connecting rod then causes the blade holder to rotate, allowing the blade holder to granulate the modified plastic entering from the feed shell within the housing, and the granulated plastic to be discharged from the discharge shell.

[0017] This utility model, by providing a slotted frame, allows the sliding frame to slide. The sliding of the sliding frame can drive the rotating bearing, connecting rod, and connecting frame to move. At the same time, the movement of the connecting rod can drive the tool holder to move. The connecting frame, in conjunction with the connecting block and the threaded pin, allows the rotary motor to be connected to or disconnected from the connecting frame and connecting rod, thereby enabling the tool holder to be quickly replaced during use.

[0018] In summary, the rotation of the rotary motor drives the connecting block, connecting frame, threaded pin, rotary bearing, and connecting rod to rotate. The rotation of the connecting rod drives the blade holder to rotate, allowing the blade holder to granulate the modified plastic. Furthermore, the detachable and reassembleable features of the connecting block, connecting frame, and threaded pin, combined with the sliding of the sliding frame within the slot frame, enable the blade holder to be easily and quickly replaced and maintained, further allowing for continuous pelletizing production.

A rotary motor 12 and a controller 2 are respectively arranged on the front surface of the shell 1. Two slotted frames 6 are fixedly connected to the inner wall of the shell 1. Two sliding frames 18 are slidably connected inside the two slotted frames 6. A rotating bearing 17 is fixedly connected to the inner wall of each sliding frame 18. Two connecting rods 15 and two blade holders 16 are respectively arranged inside the shell 1. The outer surface of each connecting rod 15 is connected to the rotating bearing. The inner wall of the inner ring of the 17 is fixedly connected. Each connecting rod 15 is fixedly connected to a connecting frame 19 at one end near the rotating bearing 17. A connecting block 13 is slidably connected inside one of the connecting frames 19. The inner walls of one of the connecting frames 19 and the connecting block 13 are threadedly connected to two threaded pins 20. The output end of the rotating motor 12 is fixedly connected to the front of the connecting block 13. In this embodiment, the outer ring of the rotating bearing 17 is fixedly connected to the sliding frame 18, while the inner ring is fixed to the connecting rod 15. Thus, the connecting rod 15 can be rotated or moved through the inner and outer rings of the rotating bearing 17.

[0031] The housing 1 has hinged doors 7 on both sides, and handles 8 are fixedly connected to the sides of the two doors 7 that are far apart from each other. In this embodiment, the housing 1 can be opened or closed by means of the doors 7, and the doors 7 can be opened or closed conveniently by means of the handles 8.

[0032] The bottom surface of the controller 2 is fixedly connected to the support plate 10, and the back of the support plate 10 is fixedly connected to the front of the housing 1. In this embodiment, the controller 2 can be fixedly used through the support plate 10. The controller 2 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0033] The bottom surface of the rotary motor 12 is fixedly connected to a fixing frame 11, and the back side of the fixing frame 11 is fixedly connected to the front side of the housing 1. In this embodiment, the rotary motor 12 can be fixed to the housing 1 through the fixing frame 11, so that the rotary motor 12 can be used stably.

[0034] The outer surface of the fixed frame 11 is fixedly connected to the protective shell 4. The front of the protective shell 4 is provided with two sets of ventilation openings 5. The protective shell 4 is fitted over the outside of the rotary motor 12. In this embodiment, the protective shell 4 can protect the rotary motor 12 inside, and the ventilation openings 5 ​​can be used to ventilate the inside of the protective shell 4, thereby extending the service life of the rotary motor 12.

[0035] Each connecting rod 15 is rotatably connected to a limiting frame 14 on its outer surface. The front of each limiting frame 14 is fixedly connected to the back of the sliding frame 18. In this embodiment, the limiting frame 14 can limit the connecting rod 15 and fix it on the sliding frame 18, thereby making the rotation of the connecting rod 15 more stable.

[0036] Each tool holder 16 has a connecting ring 21 fixedly connected to its inner wall. The inner wall of each connecting ring 21 is fixedly connected to the outer surface of the connecting rod 15. In this embodiment, the connecting ring 21 can fix the tool holder 16 to the connecting rod 15, so that the connecting rod 15 can drive the tool holder 16 to rotate.

[0037] Understandably, the rotary motor 12, connecting block 13, connecting frame 19, threaded pin 20, rotary bearing 17, and connecting rod 15 can drive the blade holder 16 to rotate within the housing 1, thereby enabling the blade holder 16 to granulate the modified plastic. The sliding engagement of the connecting block 13 and the connecting frame 19 with the threaded pin 20 allows for easy assembly and disassembly of the connecting frame 19 and the connecting block 13. Simultaneously, the sliding frame 18 can drive the rotary bearing 17, connecting rod 15, connecting frame 19, and blade holder 16 to slide and shift, allowing the blade holder 16 to be quickly replaced via the connecting block 13 and the connecting frame 19 with the threaded pin 20, further avoiding the problem of long production interruptions.

[0038] A specific application of this embodiment is as follows: In use, firstly, the rotary motor 12 and controller 2 are connected to the power supply, and the rotary motor 12 and controller 2 are connected through wires. At the same time, the housing 1 is connected to the modified plastic conveying equipment, so that the modified plastic can enter the housing 1 through the feed housing 9. After installation, the controller 2 is turned on by the wires. The turning on of the rotary motor 12 drives the connecting block 13, connecting frame 19, threaded pin 20, connecting rod 15, inner ring of rotating bearing 17 and knife holder 16 to rotate, so that the knife holder 16 cuts the plastic that has moved into the housing 1 into pellets, and at the same time moves the pellets out of the housing 1 from the discharge housing 3. When the knife holder 16 needs to be repaired or replaced, the rotary motor 12 is turned off, and the threaded pin 20 is moved out of the connecting frame 19 and connecting block 13. At the same time, the sliding frame 18 slides in the slot frame 6, so that the sliding frame 18 drives the rotating bearing 17. The connecting rod 15, the knife holder 16, and the connecting frame 19 slide, so that the connecting frame 19 no longer contacts the connecting block 13. Then, the spare sliding frame 18 drives another set of rotating bearings 17, connecting rod 15, knife holder 16, and connecting frame 19 to slide, while the connecting block 13 slides into the connecting frame 19. The connecting frame 19 and the connecting block 13 are fixed by the threaded pin 20. After the connecting frame 19 and the connecting block 13 are fixed, the rotary motor 12 is turned on again by the controller 2. At the same time, the rotary motor 12 drives the connecting block 13, the connecting frame 19, the threaded pin 20, the connecting rod 15, the inner ring of the rotating bearing 17, and the knife holder 16 to rotate and granulate. The opening and closing door 7 is opened by the handle 8, so that the sliding frame 18 and the knife holder 16 can be moved out of the housing 1 through the slot frame 6 for maintenance or replacement, thereby reducing production downtime and improving the efficiency of modified plastic pelleting production.
