Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

Embodiment 1:

As shown in Figs 1-4, a kind of injection molding waste pulverizer, it includes: crushing chamber 2.Crushing chamber 2 is cavity body structure.It crushes 2 upper end of chamber is connected with switchable the cover.Frame body 1 is connected with below crushing chamber 2.2 lower end of crushing chamber is connected with discharge port 4.Out Material mouth 4 is located at 1 top of frame body.Discharge port 4 is strip, and upper end is big, lower end is small, and 4 section of discharge port is at trapezoidal.On discharge port 4 End in 2 lower end of crushing chamber and cavity by being connected to.Crushing chamber 2 is equipped with two parallel shafts 5.Every 5 corresponding position of shaft connects It is connected to knife assembly 3.Knife assembly 3 includes knife rest 31 and blade 32.Knife rest 31 be it is discoid, it is intermediate solid by key with shaft 5 It is fixed.Blade 32 includes cutter head and cutter hub 322.The generally rectangle of blade 32.Cutter head end face is set there are two inclined-plane, and two inclined-planes connect Place is blade 321.32 section cutter head of blade is rectangular at triangle, cutter hub 322.One knife rest 31 is connected with several blades 32, eight blades 32 are shown in figure, are used only to for example, particular number is by 31 diameter of knife rest and modeling to be treated The dynamics that waste material needs is expected to determine.Blade 32 and knife rest 31 are fixed, and eight blades 32 are distributed in the side of 31 outer circle of knife rest.Often Shaft 5 is axial to be serially connected with multiple knife assemblys 3, i.e. knife rest 31 in every shaft 5 is coaxially connected with shaft 5, knife rest 31 End face be mutually adjacent to.Several knife assemblys 3 constitute coaxial knife assembly.It is shown in the figure and constitutes one with three knife assemblys 3 A coaxial knife assembly.Every shaft 5 is connected with several coaxial knife assemblies.Fig. 1, with A, B coaxial knife assembly A, same is respectively indicated in 5 Axis knife assembly B.Coaxial knife assembly A, coaxial knife assembly B adjacent each other coaxial knife assembly.The row of the blade 32 of coaxial knife assembly Mode for cloth are as follows: blade 321 mutually staggers, 322 side of cutter hub is close to each other, i.e., the cutter hub 322 of the blade 32 on adjacent knife rest 31 Lower side is overlapped, blade 321 separates, and forms V-shaped (as shown in Figure 3) in 5 shaft end orthographic projection of shaft.Knife assembly 3 is adjacent Blade 32 and 31 outer circle side of knife rest form knife interval 33.3 end face of knife assembly of two shafts 5 connection.Turn at two On the line of 5 central axes of axis, knife is connected with another shaft 5 with the insertion of blade 32 that a shaft 5 connects knife assembly 3 and is combined The knife interval 33(of body 3 is as shown in Figure 2).31 side of knife rest of the blade 321 and composition knife interval 33 that are inserted into blade 32 squeezes, and makes It obtains 31 side of knife rest and is extruded recess, amount of recess is to squeeze depth L, and L is 0.3 millimeter.

In use, falling into knife interval 33 first, two shafts 5 are into central axes line after injection molding waste enters crushing chamber 2 Heart rotation, injection molding waste are cut into segment.The injection molding waste of segment is using the line upper knife edge two 5 central axes of shaft 321 squeeze with knife rest 31 as little particle.Little particle is discharged by the discharge port 4 of lower section.
