Description

Technical Field

[0001] The utility model relates to the field of plastic particle production, and more specifically to an extrusion system for producing environmentally friendly plastic particles. Background Art

[0002] With the development and progress of modern industry, plastic particles have gradually become an indispensable and important raw material in modern production. The plastic raw materials are heated and enter the extruder. The heating system heats the raw materials to a molten state, and the extruder extrudes strips. The extruded plastic strips are cooled by the cooling system to quickly solidify and form. The cooled extruded strips are cut into small particles of the required length by the cutting device to form the final plastic particle products.

[0003] When the extruder discharges materials, it will generate hot air, which is polluting to a certain extent and will pollute the surrounding air. Operators who are exposed to the hot air for a long time may suffer from health problems such as dizziness and respiratory discomfort. The existing extrusion system introduces the hot air into the waste gas treatment device through the suction device, and the waste gas is treated and purified by the waste gas treatment device. However, in the actual operation process, the operator may turn on the extruder but forget to turn on the suction device, causing waste gas leakage, resulting in the untreated waste gas being directly discharged into the air, causing air pollution. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provide an environmentally friendly extrusion system for producing plastic particles.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly extrusion system for producing plastic particles, comprising a control unit, an extrusion unit, a fixing unit and a suction unit, the extrusion unit having a die head, the die head having a discharge hole, the fixing unit comprising a fixing plate and two L-shaped plates respectively fixed on both sides of the fixing plate, the L-shaped plate having a plurality of locking bolts, the locking bolts passing through the L-shaped plate and pressing against the extrusion unit, the suction unit comprising a suction hood, a suction pipe connected to the suction hood, a corrugated pipe connected to the suction pipe and a suction fan connected to the corrugated pipe, the suction hood abutting against the end of the extrusion unit, the suction hood having a notch, a temperature sensor being installed at the bottom of the fixing plate, the temperature sensor being located above the notch, a fixing pipe being fixedly connected to the bottom of the fixing plate, the suction pipe passing through the fixing pipe and being fixedly connected to the fixing pipe, and a mounting through hole being provided at the fixing plate for allowing the suction pipe to pass through.

[0006] Furthermore, a reinforcing plate is fixedly connected to the bottom of the fixing plate, the reinforcing plate is fixedly connected to the fixing tube, an abutting plate is fixed to the reinforcing plate, and the abutting plate can abut against the end of the extrusion unit.

[0007] The abutment plate abuts against the end of the extrusion unit, thereby making the fixing plate more stable.

[0008] Furthermore, the plurality of discharge holes are distributed in a row with equal spacing.

[0009] Therefore, the extrudate can be extruded evenly from each discharge hole, ensuring the consistency and quality stability of the product during the production process.

[0010] Furthermore, the L-shaped plate has a plurality of threaded holes matching the locking bolts.

[0011] Furthermore, each L-shaped plate is provided with four locking bolts.

[0012] This ensures that the suction unit and the extrusion unit are firmly connected.

[0013] Furthermore, the outer diameter of the air suction pipe is the same as the inner diameter of the fixed pipe.

[0014] Thereby the air suction pipe and the fixed pipe are connected firmly.

[0015] Preferably, the fixed pipe is provided with a locking bolt capable of fixing the suction pipe and the fixed pipe.

[0016] The locking bolts thus make disassembly of the suction unit more convenient.

[0017] In some embodiments, the fixed pipe and the air suction pipe are fixedly connected by welding.

[0018] Furthermore, a mounting plate is fixedly connected to the bottom of the fixing plate, and the temperature sensor is mounted on the mounting plate.

[0019] Thereby facilitating the installation and fixation of the temperature sensor.

[0020] Furthermore, the extrusion system also includes a touch screen, and the control unit performs control.

[0021] Therefore, when the suction unit is closed, when the measured value of the temperature sensor is greater than or equal to the set threshold, the control unit controls the suction fan to turn on and sends a prompt signal at the same time. And the temperature sensor can continuously monitor the temperature of the area where it is located, thereby providing a monitoring dimension for whether the entire production line is operating normally. It can remind operators to deal with abnormal situations in time to ensure smooth production.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. The extrusion system of the present application can suck the hot air generated by extrusion into the exhaust gas treatment unit through the suction hood, thereby reducing the pollution of the hot air to the environment, making the entire extrusion system more environmentally friendly and protecting the health of the operators.

[0024] 2. The extrusion system of the present application can ensure that the suction fan is automatically turned on after the extrusion starts through the temperature sensor and the control unit, so as to avoid the situation where the suction fan is forgotten to be turned on during extrusion. After the suction fan is turned on, most of the hot air can be sucked away by the effect of the negative pressure airflow, so as to avoid leakage upward through the notch.

[0025] 3. The extrusion system of the present application can continuously monitor the temperature of the area where it is located through the temperature sensor, thereby providing a monitoring dimension for whether the entire production line is operating normally. In this way, abnormal temperature conditions can be discovered in time and corresponding measures can be taken to ensure the safe and stable operation of the production line.

[0026] 4. The extrusion system of the present application is fixed by the fixing unit so that the suction unit and the extrusion unit are firmly connected to prevent the vibration and impact generated during the extrusion process from affecting the connection, thereby ensuring the normal operation of the suction unit.

[0034] A reinforcing plate 2.5 is fixedly connected to the bottom of the fixed plate 2.1, and the reinforcing plate 2.5 is fixedly connected to the fixed tube 2.4. An abutting plate 2.6 is fixed to the reinforcing plate 2.5, and the abutting plate 2.6 can abut the end of the extrusion unit 1; a plurality of discharge holes 1.1.1 are distributed in a row with equal intervals; a plurality of threaded holes matching the locking bolts 2.3 are provided at the L-shaped plate 2.2; four locking bolts 2.3 are provided at each L-shaped plate 2.2; the outer diameter of the suction tube 3.2 is the same as the inner diameter of the fixed tube 2.4; a mounting plate is fixedly connected to the bottom of the fixed plate 2.1, and the temperature sensor 4 is installed at the mounting plate.

[0035] Working principle: In the extrusion system of the present application, when the extrusion unit discharges the material, the material just coming out is hot, and the generated hot air (hot air is polluted) is sucked into the subsequent waste gas treatment unit by the suction hood, thereby making the entire extrusion system more environmentally friendly. The suction unit and the extrusion unit are firmly connected by the fixing unit. A temperature sensor is also installed, and the suction hood has a notch. In the initial state, the suction fan is closed. When the extrusion starts, a part of the hot air will flow upward through the notch and be detected by the temperature sensor (at this time, the measured value of the temperature sensor is greater than or equal to the set threshold), so that the control unit controls the suction fan to automatically turn on, ensuring that the suction fan must be turned on after the extrusion starts, avoiding the situation where the suction fan is forgotten to be turned on during extrusion. And after the suction fan is started, due to the effect of the negative pressure airflow, the hot air is basically sucked away by the suction pipe and will no longer leak upward through the notch. To close the extrusion unit and the suction unit, it is preferred to manually close them together.

[0036] In addition, during the normal operation of the extrusion system (the extrusion unit and the suction fan are operating normally), the temperature sensor can continuously monitor the temperature of the area where it is located, thereby providing a monitoring dimension for whether the entire production line is operating normally. In this way, abnormal temperature conditions can be discovered in time and corresponding measures can be taken to ensure the safe and stable operation of the production line.

[0037] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
