Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a vertical plastic mixer. Background Art

[0002] Vertical plastic mixer is a kind of equipment commonly used in plastic processing industry. It is mainly used for mixing and stirring granular plastic raw materials. The working principle of common vertical plastic mixer is: use the rapid rotation of the mixing screw to lift the plastic raw materials from the bottom of the mixing barrel from the center to the top, and then fly and scatter in an umbrella state and return to the bottom of the mixing barrel. The plastic raw materials will flow from the discharge pipe to the collection container below the discharge pipe for collection.

[0003] Since most of the plastic raw materials are in the form of tiny particles, mechanical friction will occur between the particles and between the particles and the inner wall of the mixer, causing collision and wear between the particles, which is very likely to generate dust. In addition, the existing collecting containers are of different sizes and heights. When a large height difference is formed between the discharge port and the opening of the collecting container, the dust generated by the stirred plastic particles in the falling process is very easy to be blown into the air and then become dust, thereby polluting the environment and affecting people's health. In view of the above problems, a vertical plastic mixer is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a vertical plastic mixer, which can reduce the flying of dust and thus avoid environmental pollution.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a vertical plastic mixer, comprising a frame, a mixing bin arranged on the frame, a mixing barrel, a discharge pipe, and a mixing screw rotatably arranged in the mixing barrel, characterized in that: the mixing bin comprises an upper storage shell and a lower storage shell with a discharge pipe, the lower storage shell is sealed and lifted and slidably arranged on the upper storage shell, the mixing barrel is fixedly arranged in the lower storage shell, the upper storage shell is provided with a lifting and driving assembly for driving the lower storage shell to reciprocate, the discharge pipe is arranged on the lower storage shell and a resisting baffle is arranged on the outer periphery of the discharge pipe, the resisting baffle moves with the lower storage shell and a mounting structure is provided between the two.

[0006] By adopting the above technical scheme, the mixed plastic raw materials fall into the collecting container below through the discharge pipe; the height of the discharge port is changed by driving the lower storage shell to move through the lifting drive assembly, thereby compensating for the height difference between the discharge port and the openings of different collecting containers, effectively preventing the plastic raw materials from being blown away due to the large height difference during the falling process, thereby avoiding environmental pollution and harming people's physical and mental health; by providing a resisting baffle that moves with the lower storage shell, the resisting baffle is used to cover the opening of the collecting container, and the opening of the collecting container is further isolated from the outside, thereby preventing dust from being blown away.

[0007] It is further configured as follows: the discharge pipe includes a main confluence section and two branch confluence sections merging into the main confluence section, wherein one of the branch confluence sections is connected to the inner cavity of the lower material storage shell, and the other branch confluence section is connected to the bottom of the mixing barrel.

[0008] By adopting the above technical solution, a part of the mixed plastics and another part of the difficult-to-take-out plastics in the mixing barrel are merged into the main gathering section through the branch gathering section, so that the dust of each part can be collected together to avoid excessive dust from being blown out.

[0009] It is further configured as follows: the installation structure includes a clamping ring arranged on the main section, a clamping section formed on the retaining baffle and extending to the top of the clamping ring, and a clamping ring slidably mounted on the main section and located above the clamping section, the clamping ring squeezes the clamping section and is fixed to the clamping ring, the retaining baffle extends outward toward the outer circle and is made of elastic material.

[0010] By adopting the above technical solution, the pressing section is pressed on the clamping ring, which can achieve quick disassembly and assembly, facilitate replacement and have a simpler structure; the clamping ring can make the pressing section and the clamping ring structure fast and not easy to separate directly; the blocking partition is made of elastic material with pulling and tension effects, which is used to adapt to collection containers with openings of different shapes, and more effectively prevent dust from being blown away.

[0011] It is further configured as follows: a slide groove is axially opened on the top of the mixing screw, a driving motor is arranged on the upper storage shell, and an output shaft of the driving motor is connected to a connecting rod, the connecting rod includes a connecting part and an insert rod, and the insert rod is plugged into and matched with the slide groove.

[0012] By adopting the above technical solution, as the upper material storage shell and the lower material storage shell move, the insertion rod slides relative to the slide groove to adapt to the height difference caused by the upper material storage shell and the lower material storage shell.
