Description

Technical Field

[0001] This utility model belongs to the technical field of blending modification equipment, specifically relating to a recycled polypropylene plastic blending modification equipment. Background Technology

[0002] The recycled polypropylene plastic blending modification device is a device used to improve the properties of polypropylene (PP). It improves the mechanical properties, heat resistance, and aging resistance of recycled polypropylene through blending modification technology. Blending modification involves adding other resins, rubbers, and thermoplastic elastomers to PP material to improve the thermal shock resistance, light transmittance, and static electricity resistance of PP at lower operating temperatures.

[0003] However, in actual use, those skilled in the art have found that most existing modification devices have poor modification effects due to insufficient internal mixing, resulting in poor processing of the mixed materials and affecting user experience. Furthermore, most existing mixing tanks are quite tall, requiring users to stand on a stool to add materials, which is inconvenient for users. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for the blending and modification of recycled polypropylene plastics, which has the advantages of more uniform blending and modification and convenient feeding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a recycled polypropylene plastic blending modification device, comprising a mixing tank, a discharge port at the bottom of the mixing tank, a feed port at the top of the mixing tank, a cover plate at the top of the feed port, a mixing mechanism inside the mixing tank, and a lifting mechanism outside the mixing tank.

[0006] Preferably, the mixing mechanism includes a rotating shaft rotatably connected inside the mixing tank. A stirring blade is fixedly connected to the outside of the rotating shaft. A first motor is fixedly connected to the top of the mixing tank, and the output end of the first motor is fixedly connected to the rotating shaft. Four correspondingly distributed stirring shafts are rotatably connected inside the mixing tank. Multiple evenly distributed stirring blades are fixedly connected to the outside of each of the four stirring shafts. A transmission wheel is fixedly connected inside each of the four stirring shafts. A transmission belt is rotatably connected to the outside of every two transmission wheels. Placement plates are fixedly connected to both sides of the mixing tank. A second motor is fixedly connected to the top of each of the two placement plates, and the output ends of the two second motors are respectively fixedly connected to the two transmission wheels.

[0007] Preferably, the number of stirring blades is ten, and the ten stirring blades are evenly distributed on the outside of the rotating shaft.

[0008] Preferably, two positioning plates are fixedly connected to the top of the placement plate, and the two positioning plates are located on both sides of the second motor.

[0009] Preferably, the lifting mechanism includes a base plate disposed at the bottom of the mixing tank. Two correspondingly distributed fixed columns are fixedly connected to the top of the base plate. Limit grooves are formed inside the two fixed columns. Support plates are slidably connected inside the two limit grooves. The two support plates are fixedly connected to both sides of the mixing tank. Two correspondingly distributed electric actuators are fixedly connected to the top of the base plate. The output ends of the two electric actuators are fixedly connected to the bottom of the two support plates.

[0010] Preferably, a limiting rod is fixedly connected inside each of the two limiting grooves, and the support plate is slidably connected to the outside of the limiting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By placing the plastic raw materials and additives into the mixing tank through the feed inlet, the first motor is started. At this time, the rotating shaft fixed to the output end of the first motor begins to rotate, which in turn drives multiple stirring blades fixed to the outside of the rotating shaft to rotate, initially stirring the plastic raw materials and additives. Then, two second motors are started, and the transmission wheels fixed to the output ends of the two second motors begin to rotate. Through the transmission belt, the other two transmission wheels can be driven to rotate simultaneously. At this time, the four stirring shafts rotate simultaneously, which in turn drives the stirring plates fixed to the outside of the stirring shafts to rotate, thereby secondary stirring of the internal plastic raw materials and additives. Through multi-directional stirring, the mixture can be stirred more evenly, resulting in better co-modification of the plastic raw materials and additives and ensuring better processing results for subsequent products.

[0013] 2. By activating the two electric actuators, the output ends of the two electric actuators begin to retract, which in turn drives the two fixed support plates to move downward. As the support plates move downward, they slide outside the limit rod, making the movement smoother. Subsequently, the fixed mixing tank is moved to a lower position, making it easier for the user to add material to the feed inlet, thus making it more convenient for the user to use.

[0025] In this embodiment, when it is necessary to mix the plastic raw materials and additives more evenly, the plastic raw materials and additives are first placed into the mixing tank 1 through the feed port 3. Then, the first motor 502 is started, and the rotating shaft 501 fixed to the output end of the first motor 502 starts to rotate.

Then, the first motor 502 is started. At this time, the rotating shaft 501 fixed to the output end of the first motor 502 starts to rotate, which then drives the multiple stirring blades 503 fixed to the outside of the rotating shaft 501 to start rotating and initially mix the plastic raw materials and additives. Then, two second motors 509 are started. At this time, the transmission wheels 506 fixed to the output ends of the two second motors 509 start to rotate. Through the transmission belt 507, the other two transmission wheels 506 can be driven to rotate simultaneously. At this time, the four stirring shafts 504 rotate simultaneously, which then drives the stirring shaft 5 04 The externally fixed stirring plate 505 starts to rotate, thereby secondary stirring of the internal plastic raw materials and additives. Through multi-directional stirring, the mixture can be stirred more evenly, resulting in better co-modification of plastic raw materials and additives, and ensuring better processing effect of subsequent products. When it is necessary to conveniently add materials to the mixing tank 1, the two electric actuators 603 are first activated. At this time, the output ends of the two electric actuators 603 begin to retract, and then drive the two fixed support plates 604 to move downward. When the support plates 604 move downward, they will slide outside the limit rod 605, making the movement smoother. Then, the fixed mixing tank 1 is moved to a lower position, making it convenient for the user to add materials to the feed port 3, making it more convenient for the user to use.
