The working principle is as follows; when in use, firstly, raw materials are placed in a crushing and screening mechanism 1 for primary granulation, a filter screen is arranged at the bottom of the crushing and screening machine, particles smaller than a specified size are filtered, the filtered particles are added with an adhesive, the particles added with the adhesive are injected into a forming cavity 41, the particles become particle blocks under the action of the forming cavity 41, all fine particles are adhered together under the action of the adhesive to become particle blocks, the particle blocks formed each time are identical in size under the action of the forming cavity 41, then a conveying motor 61 is started, the conveying motor 61 rotates to drive a threaded rod 62 to rotate, the threaded rod 62 is in threaded fit with a connecting seat 63, the connecting seat 63 is driven to move after the threaded rod 62 rotates, a transmission rod 67 connected with the connecting seat 63 moves synchronously when the connecting seat 63 moves, the transmission rod 67 is connected with a connecting rack 43, at this time, the connecting rack 43 moves along with the connecting rack, the driving gear 44 is driven to rotate after the connecting rack 43 moves, the driving gear 44 rotates to drive the matched rack 45 meshed with the driving gear 44 to move, so that the matched rack 45 drives the molding cavity 41 to move downwards, the clamping rods 66 are convenient for clamping the particle blocks, when the connecting seat 63 moves, the matched rod 64 arranged on the connecting seat 63 and the clamping rods 66 synchronously move, when the matched rod 64 moves to the matched plate 42, the matched rod 64 is inwards displaced under the action of the matched plate 42 because the matched plate 42 is in an arc shape, when the matched rod 64 moves to a certain position, the clamping blocks 610 arranged on the matched rod 64 are clamped into the clamping grooves 611, thereby fixing the position of the matched rod 64, simultaneously playing a role in clamping the particle blocks when the matched rod 64 moves inwards, thus, the automatic clamping effect on the particle blocks is completed, at this moment, the conveying motor 61 is reversed, the connecting seat 63 is reset, when the connecting seat 63 moves to a certain position, the lifting block 69 arranged on the mounting frame 5 can provide upward acting force for the clamping block 610, so that the clamping block 610 is separated from the clamping groove 611, after the clamping block 610 is separated from the clamping groove 611, the matching rod 64 is reset under the action of the connecting spring column 612, the clamping force on the particle blocks is relieved by the clamping rod 66, at this moment, the particle blocks fall onto the conveying belt 3, the conveying belt 3 moves to drive the particle blocks to move below the slitting rod 22, automatic slitting is completed under the action of the slitting knife in the slitting rod 22, and the size of each particle block can be ensured to meet the requirements due to the unchanged slitting knife size;
The device can carry out secondary processing with unqualified granule when using for the particulate matter after secondary processing can accord with the requirement, has reduced the disqualification rate of granule, has improved the rate of utilization of raw materials, does not need the people to be too much operation when carrying out the operation simultaneously, only need constantly add the raw materials can, has simplified operating procedure, has improved production speed.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
