Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a heat shrinkable film raw material mixing device comprises a mixing cavity 1 and a driving shaft 2 arranged at the axial position of the mixing cavity 1, wherein the driving shaft 2 is sequentially and alternately provided with a plurality of transverse cutting discs 3 and blanking discs 4 from top to bottom, each two transverse cutting discs 3 and blanking discs 4 are in one group, the transverse cutting discs and the blanking discs in the same group are attached together, the transverse cutting discs 3 are provided with a plurality of through grooves 5, the through grooves 5 are fan-shaped, the transverse cutting discs 3 are circular, the fan-shaped arrangement can be distributed uniformly, the blanking discs 4 are provided with a plurality of blanking holes 6 at positions corresponding to the through grooves 5, the through grooves 5 on the two adjacent groups of transverse cutting discs 3 are staggered, the staggered through grooves 5 on the two adjacent transverse cutting discs 3 are convenient to avoid losing the effect of the blanking disc 4 directly next layer, the top of the mixing cavity 1 is provided with a feeding hole, the sum of the sectional areas of all the blanking holes 6 on the single blanking disc 4 is larger than the sectional area of the feeding hole, so as not to produce and pile up, the meeting of the same next floor is more than or equal to the one-tenth of previous floor, be connected with auger conveyor 7 on the bottom lateral wall of material mixing chamber 1, carry away from the bottom through auger conveyor 7 after the compounding.

The driving shaft 2 is composed of a plurality of sections, each section is in transmission connection through a speed reducing mechanism, the rotating speeds of the sections are different, the transverse cutting disc 3 and the blanking disc 4 are arranged on different sections, different sections are arranged, different rotating speeds are generated, the scattering states generated between the upper layer and the lower layer are convenient to be different, the scattering effect is better improved, the rotating angular speeds of the transverse cutting disc 3 and the blanking disc 4 of the same group are different, the scattering states of particles above the transverse cutting disc 3 can be changed continuously, the driving shaft 2 is also provided with fan-blade-shaped blades 9, the blades 9 are connected onto the driving shaft 2 and are positioned above the transverse cutting disc 3, the rotating speed of the positions of the blades 9 is also different from the rotating angular speed of the transverse cutting disc 3, the two blades 9 are used, the first is for uniformly distributing materials at the top, because the position of the feeding hole is fixed, even if the transverse cutting disc 3 rotates, what the formation of material scattering on crosscut dish 3 is also an endless belt, consequently is unfavorable for the material quick from blanking hole 6 scattering, consequently trowels through the relative rotation of blade 9, makes it shakeout on crosscut dish 3, better scattering, the second then can change the position of part material, because the blade is the slope, thereby its inclined plane can carry part material change position when rotating and reach the effect of stirring.

The bottom of the driving shaft 2 is also connected with a spiral stirring blade 8, after the materials are dispersed and converged for multiple times, the materials are relatively and uniformly mixed, the stirring blade 8 arranged at the bottom is used for stirring and simultaneously avoiding the materials from forming a static angle at the position of entering the auger conveyor 7, the static angle refers to an included angle between the surface of a self-mountain and a horizontal plane when the surface of a particulate matter stacking fallow mountain is in a balanced state, the static angle refers to a range angle including a static minimum angle and a collapse angle (also called a repose angle), in the stacking and collapsing process of natural sand, when the static angle exceeds or equals to an angle, sand particles start to collapse, the collapse angle refers to a collapse angle, and when the collapse stops, another angle, namely the static minimum angle, can appear. In the process of pile collapse of the natural sand, the static angle is continuously changed between the static minimum angle and the collapse angle, the static angle is generated to cause local or whole static, and therefore the stirring blades 8 are arranged to continuously stir.

The bottom in material mixing chamber 1 is the inclined plane, and the minimum is located auger conveyor 7 and the junction in material mixing chamber 1, makes things convenient for the material to flow to auger conveyor department to avoid there being the material to carry and can not produce the dead angle position.
