Examples
As shown in fig. 1 to 7, the glass fiber reinforced plastic crushing device of the embodiment comprises a feeding machine 1, a shredder 2, a transfer machine 3 and a shearing machine 4 which are sequentially arranged; the discharge port of the feeding machine 1 is opposite to the feed port of the shredder 2, the discharge port of the shredder 2 is opposite to the feed port of the transferring machine 3, and the discharge port of the transferring machine 3 is opposite to the discharge port of the shearing machine 4; the glass fiber reinforced plastic waste enters the shredder 2 through the feeder 1 and is shredded, and the intermediate product is discharged by the shredder 2 and enters the shredder 4 through the transfer machine 3 and is shredded. The shredder 2 is arranged to shred the glass fiber reinforced plastic waste, so that shredded intermediate products are produced; the intermediate product can be sheared by arranging the shearing machine 4, so that a final product is produced; according to the application, the transfer machine 3 is additionally arranged between the shredder 2 and the shredder 4, so that intermediate products can directly enter the shredder 4 through the transfer of the intermediate products, thereby avoiding manual transfer, optimizing the operation flow and improving the production efficiency. Compared with the crushing treatment device in the prior art, the crushing device only adopts a crushing method of shearing or shredding, and the application can successively shear and shred the glass fiber reinforced plastic waste, thereby improving the crushing quality.
In this embodiment, the shredder 2 includes a shredder housing 21, two rollers 22 are installed side by side in the cavity of the shredder housing 21, and the rollers 22 rotate in opposite directions to drive the glass reinforced plastic waste to be conveyed downwards through the intermediate space; a plurality of knife boards 23 for tearing glass fiber reinforced plastic waste are formed at intervals along the length direction of the roll shaft 22, and the knife boards 23 on the adjacent roll shafts 22 are alternately arranged. The end of the roll shaft 22 penetrates out of the shredder housing 21 and is connected with an external driver, the roll shaft 22 can reversely rotate under the action of the external driver, and the rotating direction is that the approaching ends and the deviating ends of the two roll shafts 22 move downwards and upwards, so that when the glass fiber reinforced plastic waste falls on the two roll shafts 22, the glass fiber reinforced plastic waste can be driven to be conveyed downwards from the gap between the two roll shafts. Meanwhile, a plurality of knife boards 23 are further arranged on the roll shaft 22, the knife boards 23 are distributed at intervals along the length direction of the roll shaft 22, and the knife boards 23 on the adjacent roll shafts 22 are alternately formed. The blade 23 is fixed to the roller shaft and can rotate along with the roller shaft 22. When the glass fiber reinforced plastic waste falls on the two roll shafts 22, the knife plate 23 drives the glass fiber reinforced plastic waste to move downwards to enter the gap between the knife plate 23 and the knife plate 23 or between the knife plate 23 and the roll shafts 22, and the glass fiber reinforced plastic waste is crushed under the extrusion and tearing of the knife plate 23 and the knife plate 23 or between the knife plate 23 and the roll shafts 22 and falls from the gap between the two roll shafts 22. To further enhance the tearing effect, the side walls of the blade 23 are formed with bosses or grooves for increasing friction. Due to the existence of the boss or the groove, the friction force between the glass fiber reinforced plastic waste and the knife plate 23 is further increased, and the slipping phenomenon can be effectively avoided or lightened, so that the tearing effect is enhanced.
In this embodiment, a feeding channel 26 is disposed at the top of the shredder housing 21, and the feeding channel 26 is located right above the two rollers 22. A screen drum 24 is rotatably installed in the cavity of the shredder housing 21, the screen drum 24 is sleeved outside the two roller shafts 22, and a feed inlet 241 is formed in the side wall of the screen drum 24.

The screen drum 24 is connected to the side wall of the shredder housing 21 via an annular bearing, and the roller shaft 22 is also connected to the side wall of the shredder housing 21 via an annular bearing. The feeding machine 1 intermittently feeds, when the glass fiber reinforced plastic waste is fed into the shredder 2 by the feeding machine 1, the feeding port 241 faces upwards and is opposite to the feeding channel 26, the glass fiber reinforced plastic waste sequentially passes through the feeding channel 26 and the feeding port 241 and falls above the roller shafts 22, the roller shafts 22 drive the knife plate 23 to rotate and tear the glass fiber reinforced plastic waste, the torn intermediate product passes through the gap between the two roller shafts 22 and falls onto the screen drum 24, the particle size of the intermediate product is smaller than that of the screen hole, the intermediate product passes through the screen drum 24 and falls out, and the particle size of the intermediate product is larger than that of the screen hole and remains in the screen drum 24. After the shredding process of the glass fiber reinforced plastic waste, the screen drum 24 rotates for a circle, and as the screen drum 24 is internally provided with a plurality of raised bars 242 along the length direction, the raised bars 242 push the intermediate product remained in the screen drum 24 to rotate along with the rotation, and when the intermediate product rotates to the position above the roller 22, the intermediate product is thrown off under the action of gravity, returns to the roller 22 and is shredded for the second time. When the screen drum 24 rotates one circle so that the feed inlet 241 is aligned with the feed channel 26 again, the feeder 1 feeds the glass fiber reinforced plastic waste of the next batch. Intermediate products with the grain size smaller than the mesh size can be screened by utilizing the mesh size of the screen drum 24, the intermediate products meet the shredding requirement and directly pass through the screen drum 24 to fall into the next process, and intermediate products which do not meet the shredding requirement remain in the screen drum 24 and are thrown to the roll shaft 22 again for shredding again. The existing crushing treatment device can only crush the glass fiber reinforced plastic waste once, that is, the glass fiber reinforced plastic waste can be mixed and output no matter whether the glass fiber reinforced plastic waste reaches the expected crushing standard or not after the glass fiber reinforced plastic waste is crushed once, so that a large amount of waste which does not meet the crushing standard is mixed in the output finished product, and the overall quality of the finished product is seriously affected. According to the application, the intermediate products after shredding can be screened by arranging the screen drum 24 and the rotary driver 25, and intermediate products which do not meet shredding standards are sent back to the roll shaft 22 for shredding again, so that all the composite shredding standards of the intermediate products output by the shredder 2 can be ensured, and the production quality is improved.
In this embodiment, the shredder 4 includes a shredder housing 41, a rotating shaft 42 is installed in a cavity of the shredder housing 41, a movable blade 43 rotating along the rotating shaft 42 is sleeved on the rotating shaft, a plurality of fixed blades 44 connected with the shredder housing 41 are circumferentially arranged along the movable blade 43, and a gap is reserved between the fixed blades 44 and the movable blade 43. Intermediate products produced by the shredder 2 are transported into the shredding housing 41 by the transfer machine 3, the movable blades 43 rotate under the drive of an external driver, and when the intermediate products enter the gap between the movable blades 43 and the fixed blades 44, the movable blades 43 exert a pressing action on the intermediate products, so that the intermediate products and the fixed blades 44 are forced to be extruded and sheared, and the shredding is formed. The crushed product is fed out through the gap between the movable blade 43 and the fixed blade 44.
