Abstract

The utility model discloses a crushing machine for a plastic lump material, which relates to mechanical processing equipment, in particular to a plastic crushing machine. The crushing machine for the plastic lump material consists of a frame, bolts, a rolling drum, knife blades, a machine body and a rolling shaft; the machine body is mounted on the frame; two ends of the machine body are provided with upward supporting plates; the rolling shaft is mounted on the two supporting plates; the rolling drum is mounted on the rolling shaft; two end surfaces of the rolling drum are uniformly provided with five knife grooves respectively around an axle center; the rolling drum is uniformly divided into five segments by the five knife grooves which are uniformly distributed at each end of the rolling drum; three L-shaped grooves are uniformly distributed on each segment side by side; the knife blades are oblong; the knife blades are inserted into the L-shaped grooves; the oblique planes of the upper ends of the knife blades are higher than the surface of the rolling drum; and bolts penetrate through holes of the knife blades and are screwed into threaded holes of the L-shaped grooves so as to fix the knife blades on the rolling drum. The crushing machine for the plastic lump material solves the problems that a conventional plastic crushing machine has an unreasonable structure and an unsatisfactory crushing effect.

Description

The plastic block pulverizer

Technical field

The utility model relates to machining equipment, is specifically related to a kind of plastic crusher.

Background technology

There is unreasonable structure in existing plastic crusher, the unfavorable problem of crushing effect.

The utility model content

The utility model provides the plastic block pulverizer, and the utility model has solved existing plastic crusher and had unreasonable structure, the unfavorable problem of crushing effect.

For addressing the above problem, the utility model adopts following technical scheme: be made up of frame 1, bolt 2, cylinder 3, blade 5, body 6 and roller bearing 7;

Body 6 is installed on above the frame 1, and there is gripper shoe up at body 6 two ends, and roller bearing 7 is installed on two gripper shoes, and an end of roller bearing 7 stretches out a spindle nose from gripper shoe, and spindle nose is installed belt pulley; Between roller bearing 7 and the gripper shoe bearing is installed; Cylinder 3 is installed on the roller bearing 7;

Respectively be uniform-distribution with five cutter grooves 4 around the axle center on cylinder 3 both ends of the surface; Cutter groove 4 height stretch into cylinder axis from the surface but do not arrive the axle center; Cutter groove 4 axial widths are the half the of drum length, distributions that interlace of the cutter groove 4 of right ends, and the distance that staggers is half of cutter groove 4 radial distances;

Five equally distributed cutter grooves 4 of cylinder 3 every ends evenly have been divided into five lobes to cylinder, are uniform-distribution with three L grooves 8 on each lobe side by side, and L groove 8 directions are vertical with cutter groove 4, and L groove 8 is one side closed, individual screwed hole are respectively arranged near sealing the top at the back side of a side;

Blade 5 is rectangles, and blade 5 inserts in the L grooves 8, and the inclined-plane of blade 5 upper ends exceeds cylinder 3 surfaces, and corresponding section, spiral shell mosquito hole is provided with the hole on blade 5 and the L groove 8, and the screwed hole that the hole that the bolt that has a spring leaf passes blade 5 screws in the L groove is fixed in blade on the cylinder 3.

The advantage of the utility model has: rational in infrastructure, be convenient to maintenance, and crushing effect is desirable.
