Description

Pulverizing and screening device of flour mill

Technical Field

The utility model relates to a crushing apparatus technical field, especially sieve device are smashed to milling machine.

Background

In the aluminum-plastic recovery, the circuit board and the aluminum-plastic plate need to be crushed in the recovery, and the conventional crusher usually uses a plurality of toothed disks to realize crushing in a staggered manner, but the defects are obvious and are collectively shown in the following points: for a larger circuit board, the circuit board can be crushed only once from top to bottom, the crushed circuit board is in a strip shape, and a part of uncrushed larger particles are mixed in the circuit board, so that the same batch of materials can be placed into a machine from a feeding hole only to achieve the expected recovery effect, and the process is troublesome; two, current screening mechanism can only add the screen cloth by the bobbing machine and sieve, and when the material after smashing passed through the screen cloth, big granule was detained on the screen cloth, so prior art can only separately go on smashing and screening, and convenient big granule is smashed once more, and overall technology is more loaded down with trivial details, still needs the manual work to transport.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a milling machine smashes sieve material device, can not be completely broken with the granule among the effectual prior art of having solved the rubbing crusher, and efficiency is lower, and smashes the problem that the in-process can not carry out screening simultaneously.

The technical scheme includes that the crusher comprises a crusher, first gears which are mutually kneaded are fixed at the end portions of two main shafts in the crusher, gear rings are rotationally fixed on the side wall of the crusher, the circle centers of the gear rings are located at the midpoint of the central connecting line of the two first gears, a second gear is rotationally fixed on the right side wall of the crusher, the first gears can drive the gear rings to rotate through the second gears, two guide rods which are parallel to the main shafts and fixed with the side wall of the crusher are arranged at the lower side in a cavity of the crusher, a space is arranged between each guide rod and the gear rings, an arc-shaped screen which is coaxial with and meshed with the gear rings is placed in the space, a cam groove is formed in the outer side circular surface of each gear ring, a convex block is fixed on each screen, each convex block is placed in each cam groove, and the gear rings can drive the screen to move left and right through the convex blocks in a rotating mode; a plurality of fixing plates parallel to the main shaft are fixed on the gear ring, the cross section of each fixing plate is L-shaped, and the fixing plates can be in contact with the screen when rotating along with the gear ring.

The utility model discloses the structure is ingenious, can guarantee that the material thoroughly smashes in rubbing crusher, can be broken many times to not by kibbling large granule, guarantees crushing quality, smashes the in-process and realizes vibratory screening, guarantees that the tiny particle is in time released, and equipment simplifies greatly, and convenient operation does benefit to and improves work efficiency, reduces the manual work volume.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

The utility model discloses a rubbing crusher, two main shaft tip in the rubbing crusher all are fixed with the first gear 1 that kneads each other, all rotate on the rubbing crusher lateral wall and are fixed with ring gear 2, the centre of a circle of ring gear 2 is located the mid point of two first gear 1 center connecting lines, it is fixed with second gear 3 to rotate on the rubbing crusher right side wall, first gear 1 can drive ring gear 2 through second gear 3 and rotate, the intracavity downside of rubbing crusher has two guide arms 4 parallel with the main shaft and fixed with rubbing crusher lateral wall, there is the interval between guide arm 4 and ring gear 2, place the arc screen cloth 5 coaxial and the coincidence with ring gear 2 in the interval, the cam groove has been seted up on the round outside of ring gear 2, be fixed with the bulge on the screen cloth 5, the bulge is placed in the cam groove, ring gear 2 rotates and can drive screen cloth 5 through the bulge and remove; a plurality of fixing plates 6 parallel to the main shaft are fixed on the gear ring 2, the cross section of each fixing plate 6 is L-shaped, and the fixing plates 6 can be contacted with the screen 5 when rotating along with the gear ring 2.

In order to prevent the materials from splashing, two V-shaped plates 7 with downward openings are arranged on the lower side of a feeding hole of the crusher, the V-shaped plates 7 are hinged with the upper side plate, and the two V-shaped plates 7 are symmetrical front and back.

For the convenience of discharging, the lower end in the cavity of the pulverizer is fixed with an inclined steel plate 8, and the lower end of the steel plate 8 inclines downwards.

In order to install the gear ring 2, the left side plate and the right side plate of the pulverizer are provided with circular boss 9, the gear ring 2 is sleeved on the boss 9, and the boss 9 and the gear ring 2 are fixed together in a rotating mode.

It is worth noting that there are two gear rings 2, a bearing is installed between the gear ring 2 and the boss 9, and a reserved space for accommodating the first gear 1 and the second gear 3 is arranged on the boss 9.

During the use, start rubbing crusher, main shaft in the rubbing crusher rotates with comminuted, the material drops on screen cloth 5 after smashing, this moment, main epaxial first gear 1 drives ring gear 2 through second gear 3 and rotates, ring gear 2 rotates and drives screen cloth 5 horizontal vibration through protruding piece, sieve out the large granule on the screen cloth 5, all the other small granules ejection of compact downwards, ring gear 2 pivoted drives a plurality of fixed plates 6 simultaneously and rotates, fixed plate 6 will be detained the large granule on screen cloth 5 and upwards raise, get into again and carry out the breakage between two main shafts, so reciprocal, can guarantee that all materials are broken into the small granule.
