Description

Technical Field

[0001] This utility model belongs to the technical field of plastic granulation equipment, specifically a plastic granulation equipment with real-time temperature feedback. Background Technology

[0002] Plastic granulation equipment is a key piece of equipment in the plastics processing field. It can transform various plastic raw materials into uniform granular products through a series of processes. Its workflow typically includes raw material crushing, washing, melting and plasticizing, filtering impurities, extrusion molding, cooling and solidification, and pelletizing. Through this series of continuous operations, it can not only process irregularly shaped raw materials into standardized granules that are easy to store, transport, and further process, but also modify, mix, and remove impurities in the plastics during the processing. This improves the utilization efficiency of plastic raw materials and the quality of subsequent products. It is also a core piece of equipment in the recycling and reuse of waste plastics, and is of great significance to resource recycling and environmental protection.

[0003] Because plastic raw materials are diverse in form, waste plastics often contain impurities, moisture, or sticky substances, and virgin materials may also clump due to high moisture content. When these materials enter the feed inlet, they are prone to accumulation due to the narrow conveying channel and high friction. Especially in the screw feeding stage, if the raw material particles are uneven or contain hard impurities, they will get stuck in the screw gaps and form blockages over time, affecting the continuity of feeding. At the same time, the various working stages of the device are highly independent, and it is difficult to synchronize the processes of conveying, crushing, and melting. Moreover, the equipment in each stage is mostly an independent unit, which needs to be opened or closed one by one during operation. The lack of automated linkage control leads to the overall process being broken, making it impossible to form an efficient and continuous production closed loop, which significantly reduces the integration level and production efficiency of the device. Therefore, this application proposes a plastic granulation device with real-time temperature feedback. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a plastic granulation device with real-time temperature feedback, which effectively solves the problems of easy clogging and low integration of plastic granulation devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic granulation device with real-time temperature feedback, comprising a base and a vibration stirring mechanism. Multiple supports are fixedly installed at the bottom of the base. The vibration stirring mechanism includes multiple fixed frames fixedly installed on the upper part of the base. Fixed columns are slidably connected within the fixed frames and slide against the inner wall of the fixed frames. A hopper is fixedly installed at the upper end of each fixed column. A vibrating plate located between the multiple fixed columns is fixedly installed on the fixed columns. An mounting plate located between two fixed frames is fixedly installed on each fixed frame. A first motor is fixedly installed on one of the mounting plates. The output end of the first motor passes through the mounting plate and is rotatably connected to it. A rotating rod is fixedly connected to the output end of the first motor. An eccentric roller is sleeved on the rotating rod and fixedly connected to it. The eccentric roller slides against the vibrating plate. A stirring component is installed inside the hopper.

[0006] Preferably, the agitator includes a second motor fixedly installed at the bottom of the hopper, the output end of the second motor passing through the hopper and rotatably connected thereto.

[0007] Preferably, the output end of the second motor is fixedly connected to a fixing rod, and a plurality of stirring plates are fixedly connected to the fixing rod. The stirring plates slide against the inner wall of the hopper.

[0008] Preferably, the upper end of the hopper is fixedly equipped with a feed inlet that penetrates the hopper, and the side of the hopper is fixedly equipped with a flexible hose that penetrates the hopper.

[0009] Preferably, a material cylinder is installed above the base and is fixedly connected to a flexible hose. The flexible hose passes through the material cylinder, a heater is fixedly installed on the material cylinder, and a temperature detector is fixedly installed on the material cylinder opposite to the heater.

[0010] Preferably, a transmission rod is rotatably connected to the material cylinder, and gears are fixedly connected to the transmission rod and the rotating rod. A synchronous belt meshes with the two gears, and a screw is fixedly connected to the transmission rod.

[0011] Preferably, a feed pipe is fixedly installed on the feed cylinder, and a pelletizer fixedly connected to the feed pipe is installed above the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a vibration stirring mechanism, and utilizing the cooperation between the first motor, the second motor, the eccentric roller, the stirring plate, and the vibrating plate, the rotation of the stirring plate can prevent plastic from accumulating and clumping in the hopper. The sliding contact between the stirring plate and the inner wall of the hopper can scrape off the plastic on the inner wall of the hopper, preventing plastic residue from remaining in the hopper. The rotation of the eccentric roller will drive the vibrating plate to move up and down, thereby driving the fixed column to move up and down, and thus driving the hopper to move up and down. Because the hose is set at an inclination during the up and down vibration, it will drive the plastic in the hopper to slide into the hose. The plastic will slide along the hose into the material cylinder, thereby completing the plastic conveying work. The vibration of the hopper can prevent plastic from clogging the inlet, ensuring the stability of the conveying work. At the same time, the cooperation between the gears, the timing belt, and the screw can make the plastic discharge work and the shearing and extrusion work proceed simultaneously, improving the integration of the device.

[0021] Depend on Figures 1-4 The present invention includes a base 5 and a vibration mixing mechanism. Multiple supports 6 are fixedly installed at the bottom of the base 5 to ensure the stability of the base 5.

The output end of the first motor 18 passes through the mounting plate 16 and is rotatably connected to it. A rotating rod 15 is fixedly connected to the output end of the first motor 18. An eccentric roller 17 is sleeved on the rotating rod 15 and fixedly connected to it. The eccentric roller 17 slides against the vibrating plate 19.

[0022] A mixing component is installed inside the silo 1. The mixing component includes a second motor 20 fixedly installed at the bottom of the silo 1. The output end of the second motor 20 passes through the silo 1 and is rotatably connected to it. A fixed rod 21 is fixedly connected to the output end of the second motor 20. Multiple mixing plates 14 are sleeved on the fixed rod 21 and fixedly connected to it. The mixing plates 14 slide against the inner wall of the silo 1. An inlet 2 is fixedly installed at the upper end of the silo 1, passing through the silo 1. A flexible hose 12 is fixedly installed on the side of the silo 1, passing through the silo 1. A material cylinder 9 is installed above the base 5 and fixedly connected to the flexible hose 12. The flexible hose 12 passes through the material cylinder 9. A heater 10 is fixedly installed on the material cylinder 9. A temperature detector 8 is fixedly installed on the material cylinder 9 and is positioned opposite to the heater 10.

[0023] A transmission rod 24 is rotatably connected to the material cylinder 9. Gears 23 are fixedly connected to the transmission rod 24 and the rotating rod 15. Synchronous belts 22 mesh with the two gears 23. A screw 13 is fixedly connected to the transmission rod 24. A feed pipe 11 is fixedly installed on the material cylinder 9.

[0024] During operation, plastic is placed into the feed inlet 2 and the second motor 20 is turned on. The plastic will enter the hopper 1 from the feed inlet 2. The output end of the second motor 20 will drive the fixed rod 21 to rotate. The fixed rod 21 will drive multiple stirring plates 14 to rotate. The rotation of the stirring plates 14 can prevent the plastic from accumulating and clumping in the hopper 1. The stirring plates 14 slide against the inner wall of the hopper 1, which can scrape the plastic off the inner wall of the hopper 1, thus preventing plastic residue in the hopper 1.

[0027] Furthermore, the heater 10 (which can be an electric heating rod) heats the plastic, causing it to gradually melt and mix into a uniform melt from a solid state. At the same time, the temperature detector 8 (which can be a thermocouple) can detect the temperature inside the barrel 9 and then transmit the temperature information to the display screen via an electrical signal, thereby achieving real-time temperature feedback. The molten plastic then enters the pelletizer 7 through the feed pipe 11. The pelletizer 7 completes the pelletizing of the plastic, thus completing the granulation process.

[0028] Working principle: When working, plastic is put into the feed port 2 and the second motor 20 is turned on. The plastic will enter the hopper 1 from the feed port 2. The output end of the second motor 20 will drive the fixed rod 21 to rotate. The fixed rod 21 will drive multiple stirring plates 14 to rotate. The rotation of the stirring plates 14 can prevent the plastic from accumulating and clumping in the hopper 1. The stirring plates 14 slide against the inner wall of the hopper 1, which can scrape the plastic on the inner wall of the hopper 1, thus preventing plastic residue in the hopper 1.

[0029] When the first motor 18 and pelletizer 7 are turned on, the output of the first motor 18 will drive the rotating rod 15 to rotate, the rotating rod 15 will drive the eccentric roller 17 to rotate, the rotation of the eccentric roller 17 will drive the vibrating plate 19 to move up and down, thereby driving the fixed column 3 to move up and down, thereby driving the hopper 1 to move up and down. Since the hose 12 is tilted when vibrating up and down, it will drive the plastic in the hopper 1 to slide into the hose 12. The plastic will slide into the material cylinder 9 along the hose 12.
