In the present embodiment, the synchronizing lever 62 is provided as a telescopic link; the outer end of the synchronizing bar is spherical and is connected with a spherical hinge connector 621 fixed on the righting bar 43.

With the above embodiments, the usage principle and the working process of the present invention are as follows: when the device is used, the pendulum bob is pulled and locked with the corresponding righting rod, and then the righting rod 43 and the pendulum bob 41 on one side are lifted. Due to the gravity, the slide block 68 below the fixed block 65 starts to slide down along the slide rail 66, and the slide block 68 above the fixed block 65 is kept still. At the same time, the synchronizer ring 6 is rotated and moved upward by the centering rod 43. When the centralizing rod 43 and the pendulum bob 41 are lifted to a certain height, and the synchronizing ring 6 also moves upwards to a certain position, under the action of gravity and inertia, the slide block 68 below the stopping fixed block 65 slides out of the limiting groove 671, and the stopping rod 69 on the slide block 68 below the stopping fixed block 65 springs into the stopping groove 632 under the action of the pressure spring 681, so that the synchronizing ring 6 is prevented from moving upwards and downwards along the swing rod 3. The position at which the righting bar 43 is raised at this time is the starting position at which the device starts to right the swing link 3.

The first working process of the centering is the initial centering of the swing link 3 by the centering rod 43 and the pendulum 41 carrying the swing link 3 in a reciprocating pendulum motion. The method specifically comprises the following steps:

at the start position, the centering lever 43 is released and the pendulum 41 carries the pendulum 3 with it in a reciprocating pendulum movement. In the process that the righting rod 43 carries the pendulum bob 41 to swing from the side of the starting position to the other side, because of the friction force between the pendulum rod 3 and the first rotating shaft, the slide block 68 is subjected to negligible friction resistance, the downward swinging acceleration of the pendulum rod 3 is smaller than the downward sliding acceleration of the slide block 68, that is, the slide block 68 can slide out of a farther position, and the position of the slide block 68 is gradually changed into a position above the fixing block 65 after the lower end of the pendulum rod 3 passes through the lowest point of the pendulum. And after the lowest point of the swing link 3 passes through the lowest point of the pendulum, the position of the other slide block 68 is gradually changed from the upper part of the stopping fixing block 65 to the lower part of the stopping fixing block 65.

When the swing rod 3 reaches the highest point on the other side of the starting position, the swing rod 3 falls, and the acceleration of the slider 68 positioned below the stopping and fixing block 65 is greater than that of the swing rod 3. At this time, the sliding block 68 above the fixing block 65 is relatively close to the corresponding limiting groove, and the sliding block 68 below the fixing block 65 slides out of the limiting groove 671 into the stopping groove 632. The relative position of the synchronizing ring 6 on the rocker 3 remains unchanged during the reciprocating pendulum movement of the centering bar 43 and the pendulum 41 carrying the rocker 3. Due to the action of the synchronizing ring 6, the included angles between the two pendulums 41 and the two corresponding righting rods 43 and the swing rod 3 are the same, and the swing rod 3 swings towards a vertical state under the action of gravity and inertia.

Due to the friction between the rocker 3 and the first shaft 2, the rocker 3, together with the centering bar 43 and the pendulum 41, eventually comes to rest after several reciprocating pendulum movements of the rocker 3. After repeated pendulum movement, the swing rod 3 is in a nearly vertical state. The initial centering stage of the swing link 3 is completed.

At this time, also because of the friction between the swing link 3 and the first rotating shaft 2, a small included angle exists between the swing link 3 and the vertical direction, and the swing link needs to be further straightened.

The second operation of righting is to perform precise righting by the impact of the pendulum 41 on the righting bar 43. The method specifically comprises the following steps:

after the first phase is completed, the pendulum 3 is in an almost vertical rest position. The two sliders 68 are reset into the limit grooves by the tension spring. The limit of the synchronizing ring 6 is released, and the pendulum bob presses the righting rod 43 on the corresponding side to be close to the swing rod 3 under the driving of the synchronizing ring 6. When the two righting rods 43 are in the same plane, the swing rod 3 is parallel to the righting rods 43, and the righting rods 43 approach to be vertical.

Since the two pendulums 41 are symmetrical about the second plane of symmetry, i.e. the two pendulums 41 are at the same angle to the pendulum rod 3. And since the swing rod 3 deviates from the vertical, the positions of the two pendulums 41 are necessarily in a high-low state. The righting pressure of the pendulum 41 at the higher position on the righting rod 43 is relatively greater than that of the pendulum 41 at the lower position on the righting rod 43, so that the righting of the swing link 3 is facilitated.

In addition, the pendulum 41 presses the righting rod 43 to contact the swing rod 3, then certain impact force is generated, the pendulum 41 and the righting rod 43 are driven by the impact force reaction force to have multiple righting swinging on the device, and the swinging rod 3 only approaches to the vertical state more and more due to the fact that the impact force of the pendulum 41 and the righting rod is reduced progressively without righting.

After the mechanism is righted, the fastening bolt 8 on the swing rod 3 is loosened, the swing rod 3 is made to fully contact the ground, and then the fastening bolt 8 is screwed, so that the swing rod 3 plays a supporting role. Similarly, after righting, the locking member 416 between the righting bar and the pendulum is disengaged, the righting bar and the pendulum are separated, and then the fastening bolt 8 is tightened after the hammer rod 411 of the pendulum 41 is extended to contact the ground.

And mounting the cutting platform at the upper end of the swing rod 3. Then the connecting sleeve 413 is arranged at the upper end of the hammer rod 411, then the length of the connecting sleeve 413 is adjusted and is in contact with the cutting platform, and the relative position of the connecting sleeve 413 is fixed through a fastening bolt 8. The pendulum 41 is then fixed to the ground by the fastening pins 414, while the cutting deck is subjected to a relatively stable supporting force. If the shredder mechanism is placed too heavy, additional support posts 415 may be added to the pins 414 to provide stability to the overall mechanism.

The invention discloses a using method of an energy-saving plastic cutting and crushing device, which comprises the following steps:

s1: firstly, the pendulum bob is pulled and locked with the corresponding righting rod, then the righting rod 43 on one side is lifted to a certain height with the pendulum bob 41, and the synchronizing ring 6 moves up to a certain position. Under the action of gravity and inertia, the slide block 68 below the stopping fixed block 65 slides out of the limiting groove, and the stopping rod on the slide block 68 below the stopping fixed block 65 springs into the stopping groove 632 under the action of the pressure spring to prevent the synchronous ring from sliding up and down relative to the swing rod.

S2: the righting rod 43 and the pendulum bob 41 are released, so that the pendulum rod 3 is driven to do reciprocating pendulum motion. And in the process that the righting rod 43 and the pendulum bob 41 drive the swing rod 3 to do reciprocating pendulum motion, the relative position of the synchronous ring on the swing rod 3 is kept unchanged. Due to the action of the synchronizing ring, the included angles between the two pendulums 41 and the two corresponding righting rods 43 and the swing rod 3 are the same, and the swing rod 3 swings towards a vertical state under the action of gravity and inertia. Under the action of frictional resistance, the pendulum rod 3 is in an almost vertical static state after the pendulum moves.

S3: the two sliders 68 are reset into the limit groove 671 by the tension spring 682, and the limit of the synchronizing ring 6 is released. The pendulums 41 on both sides are then pressed against the righting bar 43 on the respective side. The pendulum 41 brings the righting rod 43 and the swing rod to contact and then rebound, and the pendulum 41 repeatedly straightens the righting rod 43 for multiple times and then stops. The swing link 3 at this time is closest to the vertical state.

S4: loosening the fastening bolt 8 on the oscillating bar 3 to make the oscillating bar 3 fully contact the ground, and then screwing the fastening bolt 8. Similarly, after righting, the locking member 416 between the righting bar and the pendulum is disengaged, the righting bar and the pendulum are separated, the shank 411 of the pendulum 41 is extended to contact the ground and the fastening bolt 8 is tightened.

S5: and mounting the cutting platform at the upper end of the swing rod 3. Then the connecting sleeve 413 is arranged at the upper end of the hammer rod 411, then the length of the connecting sleeve 413 is adjusted and is in contact with the cutting platform, and the relative position of the connecting sleeve 413 is fixed through a fastening bolt 8. The pendulum 41 is then fixed to the ground by means of the fastening pins 414. If the shredder mechanism is placed too heavy, additional support posts 415 may be added to the pins 414 to provide stability to the overall mechanism.

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.
