A waste collecting process for hardware processing comprises the following steps:
s1: guiding waste materials generated by hardware processing into a crushing device through a conveying device;
s2: turning on the motor 141 of the crushing device to drive the crushing ring to rotate; the primary grinding cavity a is used for carrying out primary crushing on the waste; the rotation of the crushing ring enables the first grinding cutter 182 group and the grinding column 1 tooth group to be matched with each other, the waste in the primary grinding cavity a is crushed and ground, and the crushed waste is screened by the screening net 20;
s3: waste material which cannot be screened by the screen mesh 20 enters the secondary screening chamber from the primary grinding chamber a through the screening holes 185; the waste materials are transferred from the primary grinding cavity a to the secondary grinding cavity b through centrifugal force, and the volume of the secondary grinding cavity b is reduced to further crush the waste materials;
s4: and the crushed materials are recycled through a recycling device.
During operation, the waste materials generated in the hardware processing production process are guided into the feed hopper. Then the motor 141 is turned on, the motor 141 rotates to drive the driving wheel 142 to rotate through the output shaft, the driving wheel 142 rotates to drive the driven wheel 144 to rotate through the transmission belt 143, the rotation of the driven wheel 144 further drives the sliding column sleeve 15 to rotate on the material guide pipe 112, and further the sliding column sleeve 15 drives the crushing ring to rotate through the connecting rod 16. The waste material passes from the feeding hopper 111 through the material guiding pipe 112 downwards to enter the primary grinding chamber a, and the first grinding blade 182 penetrates into the space between two adjacent grinding cylindrical blades 121 in the initial state. The rotation of crushing ring makes first grinding sword 182 group and grinding column tooth group mutually support, grinds the waste material in the one-level grinding chamber a and carries out crushing grinding, and the waste material after being ground the breakage is screened by the screen cloth and is handled. Along with the increase of waste materials which can not be crushed and ground fully in the primary grinding cavity a, the grinding resistance of the crushing ring is increased, the waste materials in the primary grinding cavity a extrude the crushing plate 18 outwards, so that the first vertical edge slides outwards along the inner surface of the corresponding screening plate through the connecting slide rod 17, one end of the connecting slide rod 17 rotates around the second vertical edge along with the sliding of the first vertical edge and drives the lower end of the connecting rod 16 to slide outwards, the connecting rod 16 drives the sliding column sleeve 15 to slide downwards on the material guide pipe 112, and the position of the driven wheel 144 relative to the material guide pipe 112 is unchanged because the driven wheel 144 can slide on the sliding column sleeve 15. The first vertical edge slides outwards on connecting slide bar 17, and then makes the contained angle grow between connecting slide bar 17 and the screening board, and the screening hole 185 area on the screening board also increases simultaneously, and the volume through the waste material also grow, the volume grow of one-level grinding chamber a. Waste material that cannot be screened by the screening mesh passes from the primary grinding chamber a through the screening apertures 185 into the secondary screening chamber.
Along with first vertical edge outwards slides along the internal surface of corresponding screening plate, second grade grinding chamber b volume diminishes, consequently second grinding sword 181 deepens gradually in two adjacent grinding wall knives 191's the interval, and then makes the waste material that gets into in second grade grinding chamber b grind by further breakage grinding, by the broken waste material of abundant grinding, elected by the screening mesh screen. Meanwhile, the distance between the first grinding blade 182 and two adjacent grinding column blades 121 in the first-stage grinding cavity a is increased, the grinding and crushing efficiency in the first-stage grinding cavity a becomes low, a large amount of waste materials enter the second-stage grinding cavity b from the screening holes 185, the grinding and crushing pressure of the second-stage grinding cavity b is increased at the moment, the grinding resistance of the crushing ring is increased, the waste materials in the second-stage grinding cavity b extrude the crushing plate 18 inwards, the first vertical edge slides inwards along the inner surface of the corresponding screening plate, the included angle between the connecting slide bar 17 and the corresponding screening plate is reduced, the first grinding blade 182 penetrates into the space between the two adjacent grinding column blades 121 again, the area of the screening holes 185 is reduced, the sliding column sleeve 15 slides upwards through the connecting rod, the upward sliding distance of the sliding column sleeve 15 is increased, and the reset spring 13 is compressed to store force. At this time, the volume of the secondary grinding cavity b is increased, in the process of increasing the volume of the secondary grinding cavity b, the waste which is not sufficiently crushed and ground in the secondary grinding cavity b enters the primary grinding cavity a from the screening hole 185, the waste is sufficiently crushed and ground again in the primary grinding cavity a, and the ground waste falls down from the screening net.
After the grinding is finished, the compression return spring 13 is released, the sliding column sleeve 15 is pushed to slide downwards to return to the initial position, and the crushing ring is restored to the initial state through the connecting rod 16.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
