Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses EVA sheet banbury mixer. Referring to fig. 1, the EVA sheet internal mixer includes a premixing chamber 1 arranged on the top end, the inner cavity of the premixing chamber 1 is cylindrical, the lower end of the premixing chamber 1 is connected with a material guide hopper 2, the material guide hopper 2 is gradually closed from top to bottom, the lower end of the material guide hopper 2 is vertically connected with a connecting pipe 3, and the lower end of the connecting pipe 3 is connected with an internal mixing chamber 4.

Specifically, referring to fig. 1 and 2, the upper end of the premixing chamber 1 is connected with a feeding pipeline 5, the middle position of the inner cavity of the premixing chamber 1 is vertically and rotatably connected with a first stirring shaft 6, and the upper end of the premixing chamber 1 is provided with a first driving motor 7 for driving the first stirring shaft 6 to rotate. A plurality of first stirring blades 8 are fixedly connected to the first stirring shaft 6, the first stirring blades 8 are arranged at intervals along the circumferential direction of the first stirring shaft 6, the two first stirring blades 8 are a group of stirring assemblies, and the stirring assemblies are arranged at intervals along the length direction of the first stirring shaft 6. Three first stirring vane 8 that are located the homonymy keep away from vertical fixedly connected with scraper blade 9 between the one end of first (mixing) shaft 6, and scraper blade 9 is circular-arc, and scraper blade 9 contradicts on premixing chamber 1's inside wall along premixing chamber 1's direction of height.

Referring to fig. 3, a second stirring shaft 10 is horizontally and rotatably connected to a position close to the material guiding hopper 2 in the connecting pipe 3, three second stirring blades 11 are circumferentially arranged on the second stirring shaft 10 at intervals along the length direction, and a second driving motor 12 for driving the second stirring shaft 10 to rotate is arranged outside the connecting pipe 3.

Referring to fig. 1, an electromagnetic valve 13 is arranged at one end of the connecting pipe 3 close to the mixing chamber 4, and the electromagnetic valve 13 is a normally closed electromagnetic valve 13.

Two stirring rotors 14 are rotatably connected in the mixing chamber 4, the two stirring rotors 14 are arranged in the mixing chamber 4 at intervals in parallel, and the lower end opening of the connecting pipe 3 is just aligned with the gap between the two stirring rotors 14. The side wall of one side of the banburying chamber 4 is connected with a discharging pipeline 15.

According to the needs of products, various materials are put into the premixing chamber 1 from the feeding pipeline 5 according to a certain proportion, the first driving motor 7 drives the first stirring shaft 6 to rotate, the first stirring shaft 6 drives the first stirring blade 8 to rotate, and the first stirring blade 8 drives the scraper blade 9 to rotate. The first stirring blade 8 stirs the material in advance, so that the material is sufficiently mixed. In the stirring process, some powdery materials and liquid materials are mixed and then are adhered to the inner side wall of the premixing chamber 1, and the scraping plate 9 can scrape the materials adhered to the inner side wall of the premixing chamber 1 when rotating, so that all the materials can completely fall into the material guide hopper 2.

After the material fell into guide hopper 2, the material was more intensive, and in the material fell into connecting pipe 3 after that, second driving motor 12 driven second (mixing) shaft 10 rotated to make second stirring vane 11 carry out the secondary and stir in advance to the material, the material reached better mixed effect after stirring once more.

After the secondary pre-stirring, the electromagnetic valve 13 is opened, the material quickly falls into the gap between the two stirring rotors 14 through the connecting pipe 3, the material is extruded and sheared by the two stirring rotors 14, the material passes through the gap between the two stirring rotors 14 and is divided into two parts, and then the two parts respectively return to the upper part of the stirring rotors 14 along the gap between the side wall of the mixing chamber 4 and the stirring rotors 14, so that the two parts reciprocate, and the material is sheared to have a certain dispersity.

Above-mentioned in-process, the material is through abundant, even mixture after twice preliminary mixing, simultaneously, because the continuous scraping material of scraper blade, pulverous material can be complete fall in guide hopper 2 and finally fall into mixing chamber 4, the ratio is roughly unchangeable around the material to the material can reach intensive mixing's effect, consequently, the mixing quality of material is higher, and the product quality who produces at last is also better.

In this embodiment, second driving motor 12 and solenoid valve 13 electric connection, the staff sets up the length of time of rotation of second driving motor 12 in advance according to the required preliminary mixing time of material, and after second driving motor 12 stall, solenoid valve 13 is automatic to be opened the very first time, and the staff need not to wait by the side.

Further, referring to fig. 2, the scraper 9 is provided with a spike 16 on one side facing the rotation direction, and the spike 16 can more easily scrape off the materials stuck on the inner side wall of the premixing chamber 1 during the scraping process of the scraper 9.

The plurality of first agitating blades 8 are all disposed obliquely downward toward one side. First stirring vane 8 is at the in-process of stirring, and the resistance that first stirring vane 8 received is littleer, and simultaneously, first stirring vane 8 can be better stir the material to stirring efficiency has been improved.

Referring to fig. 3, the three second stirring blades 11 are all disposed to be bent toward one side, and a plurality of material guide holes 17 are spaced apart from each other on the three second stirring blades 11. The second stirring vane 11 of crooked has stronger shearing force to can be better stir the material, simultaneously, at the in-process of stirring, the material can pass in a plurality of stock guides 17, and the material is cut apart into littleer volume, can mix more evenly between the material.

The implementation principle of the EVA sheet internal mixer in the embodiment of the application is as follows: throw into with various materials with certain ratio in premixing room 1, the material is through the first preliminary mixing of first stirring vane 8, and the stirring in-process, powdered material can glue on premixing room 1's inside wall, and these materials can then be scraped off to scraper blade 9 to guarantee that the material gets into in the guide hopper 2 completely. The material enters into the connecting pipe 3 through the material guide hopper 2, the material is pre-stirred for the second time through the second stirring blade 11, after the stirring is finished, the electromagnetic valve 13 is opened, the material enters the banburying chamber 4 quickly, and the two stirring rotors 14 repeatedly shear the material, so that the material reaches a certain dispersion degree. The mixing quality of the materials in the mixing chamber 4 is higher because the front and back mixture ratio of various materials is approximately unchanged and the materials are premixed twice.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
