The working principle of the plastic particle melting device 100 for plastic processing provided by the embodiment of the invention is as follows:

after plastic particle materials are poured into the feed hopper 102, the motor 107 is started, so that the shaft of the motor 107 drives the elliptical wheel 109 to rotate, the elliptical wheel 109 pushes against the two top plates 110 to move, the two top plates 110 move to the side away from each other, the two top plates 110 move to drive the two mounting frames 105 to move, the two mounting frames 105 both slide on the telescopic rods 112 through the telescopic grooves 111, the springs 113 are pulled to bear force, meanwhile, the two mounting frames 105 move to drive the two blocking plates 104 to move, the two blocking plates 104 move to the side away from each other, so that the plastic in the feed hopper 102 can leak out through the gaps between the two blocking plates 104, along with the continuous rotation of the shaft of the motor 107, the elliptical wheel 109 does not push against the two top plates 110, under the action of the contraction force of the springs 113, the two mounting frames 105 move to the side close to each other, and then make two barrier plates 104 reset, thereby the spill of separation plastics, two drive rods 120 that drive are moved through two fixing bases 119 to two mounting brackets 105 simultaneously, two drive rods 120 move and drive two swinging arms 115 and rotate, and then make two swinging arms 115 drive two and strike piece 116 and strike feeder hopper 102, thereby avoid plastics because the problem of humidity class is attached to on feeder hopper 102, and then can realize when motor shaft 108 rotates a week, make two barrier plates 104 round trip movement once, thereby can realize intermittent type feeding, two swinging arms 115 can swing once simultaneously, thereby strike feeder hopper 102 once.

In addition, it should be noted that, in the actual working process of the device, the material is often added into the feeding hopper 102 at one time, and in the whole feeding process, because the height of the material is different, the internal pressure generated by the gravity of the material is different, so that the phenomenon of uneven feeding speed is often caused, the plastic particle melting device 100 for plastic processing provided by this embodiment increases the first signal fed back by the gravity sensing system in real time when there is more plastic particle material in the feeding hopper 102 through the linkage arrangement of the gravity sensing system and the control system on the blocking plate 104 and the motor 107, and correspondingly reduces the rotating speed fed back to the motor 107, so as to reduce the reciprocating speed of the two blocking plates 104, and further reduce the feeding speed, and vice versa. Therefore, the gravity sensing system and the control system are arranged in a linkage way with the motor on the blocking plate 104, so that the uneven feeding speed caused by different amounts (corresponding to the heights in the feeding hopper) of materials is effectively prevented, the failure rate of the device is reduced, and the processing efficiency of products and the stability of the product quality are improved.

It should be noted that this embodiment is configured because, in actual conditions, when there are many material particles, the required driving force is firstly increased, and secondly, the two motors 207 are driven on both sides of the mounting frame 205, which is certainly much better than the stability and smoothness of driving on one side of the mounting frame 205.

In addition, in the present embodiment, each top plate 210 is preferably provided with a wear-resistant lubricating layer at a position where it contacts with the corresponding elliptical wheel 209.

Specifically, when the barrier plate 204 performs reciprocating motion in the plane, the bottom of the corresponding hollow rack 234 is driven to move correspondingly, and the movement of the hollow rack 234 corresponding to the bottom can make the top of the hollow rack 234 slide up and down on the inner side wall of the feed hopper 202, so that the reciprocating spatial rotation motion of the hollow rack 234 is represented, and the spatial rotation motion of the hollow rack 234 plays a good role in stirring plastic particle materials in contact with the periphery of the hollow rack, thereby effectively preventing the materials from being blocked stably due to moisture or excessive materials, and ensuring that the materials are fed more smoothly; in addition, the hollow rack 234 is selected instead of the solid plate in this embodiment because the hollow rack 234 bears less pressure on the corresponding surface relative to the solid plate, so that the stirring is easier and more sufficient, and the corresponding stirring effect is better.

In summary, according to the plastic particle melting device for plastic processing provided by the embodiment of the invention, the two blocking plates can move back and forth during blanking of the feeding hopper through the linkage control arrangement of the two blocking plates and the motor, so that feeding can be blocked, and plastics in the feeding hopper can intermittently enter the device body, so that the plastic particles can be sufficiently melted, the failure rate in the feeding process is reduced, the overall feeding efficiency is improved, and the production quality of the device body is finally ensured.
