Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1, an embodiment of the present invention provides a plastic crusher, including: a housing 1; the screen 6 is arranged in the machine shell 1 and divides the internal space of the machine shell 1 into a crushing bin 9 positioned above and a crushed material collecting bin 7 positioned below; a pair of crushing rollers 2 arranged side by side, each crushing roller 2 being rotatably arranged in the crushing bin, the rotation axis of each crushing roller 2 extending horizontally; a pair of rotary drive mechanisms, each rotary drive mechanism being connected to each crushing roller to drive each crushing roller in rotation; a pair of baffle plates 3 arranged in the crushing bin, wherein each baffle plate is arranged corresponding to each crushing roller, one end of each baffle plate 3 is connected to the shell 1, the other end of each baffle plate extends to the lower part of the corresponding crushing roller 2, each baffle plate 3 is separated from the corresponding crushing roller 2 by a certain distance, each baffle plate 3 is provided with a fixed crushing knife 4 on one side facing the corresponding crushing roller, and the other ends of the pair of baffle plates are separated from each other.

The utility model provides a plastics breaker during operation treats that broken plastics are dropped into to the casing in, and a pair of crushing roller of a pair of rotary drive mechanism drive is rotatory with opposite direction, and plastics fall under the action of gravity, contact with the crushing roller to by a pair of crushing roller extrusion cutting, thereby broken into plastic granules. A baffle plate is arranged below the crushing roller, one end of the baffle plate is connected to the shell, and the other end of the baffle plate extends to the lower part of the crushing roller. When the plastic particles move downwards to the lower part of the crushing roller, the plastic particles are blocked by the baffle plate and are positioned in a space between the crushing roller and the baffle plate, and the plastic particles in the space can be driven by the rotating crushing roller to return to the upper part of the crushing roller again and are cut and crushed by the crushing roller again. And the baffle is provided with fixed crushing sword in the side towards the crushing roller, and when the plastic pellet was in the space between baffle and the crushing roller, fixed crushing sword also can play the effect of crushing the plastic pellet. The other ends of the pair of baffles are spaced from each other, and broken plastic particles can pass through the other ends of the pair of baffles, fall onto the screen and enter the crushed material collecting bin through screening of the screen.

Wherein, the crushing roller includes broken axle and sets up the rotatory crushing blade on broken axle, and these rotatory crushing blades cut the breakage to plastics at the rotatory in-process of broken axle. The rotation direction of the crushing roller on the left side can be set clockwise, while the rotation direction of the crushing roller on the right side can be set counterclockwise.

To sum up, plastics breaker set up the baffle in the casing, this baffle setting can reduce the dead angle position that plastic granules gathered between crushing roller and screen cloth in the below of crushing roller, makes this part plastic granules fully contact with the crushing roller and by abundant breakage, and then improves the crushing efficiency to plastics to and improve plastic granules size distribution's homogeneity.

Preferably, in the plastic crusher, each baffle 3 has an arc-shaped structure curved toward the side of the corresponding crushing roller 2.

In order to further reduce the dead angle space in the casing, the baffle is set into an arc structure. The plastic particles with larger size crushed by the crushing roller can move upwards along the arc-shaped baffle along with the rotation of the crushing roller, so that the plastic particles are crushed again by the crushing roller.

Preferably, in the plastic crusher, the other end of each baffle plate overlaps the screen. The other end overlap joint of baffle is on the screen cloth, and to the plastic granules that size is suitable, can directly fall into crushed aggregates through the sieve mesh of screen cloth and collect the storehouse in, and to the great plastic granules of size, it is under the drive of crushing roller, gets back to the top of crushing roller again along baffle upward movement, continues to be cut broken by the fixed broken sword on crushing roller and the baffle.

As shown in fig. 2, preferably, the plastic crusher further includes: air supply mechanism, air supply mechanism includes air supply pipe network 5, air supply main pipe and fan, the fan set up in the outside of casing, the fan communicate to the air supply main pipe, the air supply main pipe communicate to air

supply pipe network

5, 5 range upon range of settings in the screen cloth 6 top, and set up in the below of a pair of baffle, air supply pipe network 5 is formed by a plurality of air supply branch pipes 12 intercommunication of arranging with great ease, a plurality of air supply branch pipes 12 in the air supply pipe network are arranged and are formed the blanking mouth 13 of a plurality of fretworks, the air supply pipe network has a plurality of supply-air outlets of opening up.

In order to further improve crushing efficiency, avoid plastic granules to gather in the crushing roller below to and improve plastic granules size distribution's homogeneity, the utility model discloses air supply mechanism has been set up. The fan is responsible for through the air supply and supplies air to the air supply pipe network, blows the air and blows off via the supply-air outlet of air supply pipe network, reduces the speed of plastic granules whereabouts, and then strengthens the crushing effect of crushing roller to plastic granules, improves crushing efficiency. The fan can be in stage work, and when the fan stopped the air feed, plastic granules fell to the screen cloth through the blanking mouth that send the branch pipe net, falls into to the crushed aggregates through the sieve mesh again and collects the storehouse.

Preferably, in the plastic crusher, the opening directions of the plurality of air supply outlets of the air supply pipe network 5 are not consistent; the other end of each baffle 3 is lapped on the air supply pipe network 5.

The direction of the supply-air outlet of the air supply pipe network is inconsistent, the blowing effect of the air supply pipe network on plastic particles can be improved, the non-uniformity of the plastic particles flowing in the shell is enhanced, the crushing effect of the crushing roller on the plastic is further enhanced, the crushing efficiency of the plastic is improved, and the uniformity of the size distribution of the plastic particles is improved.

Preferably, in the plastic crusher, the casing 1 is mounted on a frame; the side wall of the machine shell 1 is provided with a transparent observation window 10, and the observation window 10 is arranged between the air supply pipe network and the pair of crushing rollers.

The crushing condition of plastics in the casing can be observed through the observation window, and then the operating condition of adjustment fan. For example, the fan is turned off and the plastic granules fall down to the screen. Or the fan is started to enable the plastic particles to continuously move in the crushing bin so as to be continuously cut and crushed by the crushing roller.

Preferably, in the plastic crusher, the top of the casing 1 is provided with a feeding hole, and the bottom of the casing is provided with a discharging hole 8; the top of casing is provided with feeder hopper 11, feeder hopper 11 with the feed inlet intercommunication.
