[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0030] The feeding assembly of the plastic pellet processing machine includes a storage box 1 for storing plastic pellets. The inner wall spacing of the storage box 1 near the bottom gradually decreases from top to bottom, which is used to guide the moving direction of the plastic pellets. A perspective plate 11 is embedded in the middle position of the front side of the storage box 1. The perspective plate 11 is made of acrylic material, so that the number of plastic pellets contained in the storage box 1 can be observed through the perspective plate 11, so as to replenish the plastic pellets in time. The top of the storage box 1 is hinged with a cover plate 12 to prevent external dust from falling into the storage box 1 when idle and causing pollution to the plastic pellets;

[0031] The bottom of the storage box 1 is connected with a feed barrel 2 for guiding the moving direction of the plastic particles. The bottom end of the feed barrel 2 is connected with the feed port of the plastic granules. A roller shaft 21 is rotatably connected at the center of the feed barrel 2. The outer wall of the roller shaft 21 is provided with a plurality of partitions 211 arranged in a circular array. The sum of the length of the partition 211 and the radius of the roller shaft 21 is half the length of the feed barrel 2. When the partition 211 swings to be perpendicular to the side wall of the feed barrel 2, the end of the partition 211 away from the roller shaft 21 contacts the inner wall of the side of the feed barrel 2.

[0032] Furthermore, the number of the partitions 211 is an even number, and when one of the partitions 211 swings to be perpendicular to the side wall of the feed barrel 2, the end of another partition 211 located on the same horizontal line away from the roller shaft 21 contacts the inner wall of the other side of the feed barrel 2, so that the two corresponding partitions 211 jointly block the center of the feed barrel 2, thereby stopping the feeding into the plastic pellet processing machine;

[0033] As a preferred embodiment of the present invention, a driving motor 22 is installed on the outer wall of the feed barrel 2 and at a position corresponding to the roller shaft 21. One end of the roller shaft 21 passes through the inner wall of the feed barrel 2 and is coaxially connected to the output shaft of the driving motor 22. As is well known to those skilled in the art, the driving motor 22 drives the roller shaft 21 to rotate after power is supplied, so that the multiple partitions 211 swing accordingly and transport the plastic particles entering the feed barrel 2 in batches, thereby avoiding blockage of the plastic particles during movement in the feed barrel 2.

[0034] A baffle plate 3 is provided on both sides of the left and right sides of the storage box 1 and near the bottom. The two baffle plates 3 are symmetrically distributed and the spacing is adjustable. The tops of the corresponding ends of the two baffle plates 3 are inclined surfaces. A rectangular plate 4 is provided on the front and rear sides of the storage box 1. The baffle plate 3 is slidably connected to the rectangular plate 4 through a connecting block 31. The side wall of the rectangular plate 4 is provided with a slide groove slidably connected to the connecting block 31.

[0035] As a preferred embodiment of the present invention, a bidirectional screw 41 is provided between the two front connecting blocks 31, and the two ends of the bidirectional screw 41 are respectively threadedly connected to the corresponding connecting blocks 31, and the bidirectional screw 41 is composed of a cylindrical rod and two threaded rods, and the two threaded rods are symmetrically distributed at the two ends of the cylindrical rod, and the bidirectional screw 41 is rotatably connected to the corresponding rectangular plate 4;

[0036] Furthermore, a servo motor 43 is installed on the side wall of the front rectangular plate 4 and at a position corresponding to the center of the bidirectional screw 41. One end of the bidirectional screw 41 is coaxially connected to the output shaft of the servo motor 43 through a rotating shaft, and the rotating shaft is rotationally connected to the corresponding rectangular plate 4. As is well known to those skilled in the art, the servo motor 43 drives the rotating shaft and the bidirectional screw 41 to rotate after power is supplied.

[0037] As a preferred embodiment of the present invention, a positioning rod 42 is provided between the two rear connecting blocks 31. The positioning rod 42 is slidably connected to the corresponding connecting block 31, and the end of the positioning rod 42 is fixedly connected to the inner wall of the end of the corresponding moving groove, so that the moving trajectory of the corresponding connecting block 31 can be guided and restricted by the positioning rod 42 to avoid position displacement of the connecting block 31 during movement.

[0038] When the feeding assembly of the plastic granule processing machine of the utility model is in use, the cover plate 12 is hingedly rotated, and then the cover plate 12 is reset after the plastic granules are put into the storage box 1, and the servo motor 43 is connected and started, so that the servo motor 43 is powered and drives the rotating shaft and the bidirectional screw 41 to rotate. At this time, the two connecting blocks 31 threadedly connected to the two ends of the bidirectional screw 41 move synchronously and in opposite directions along the axial direction of the bidirectional screw 41. At the same time, the other two connecting blocks 31 move synchronously and in opposite directions along the axial direction of the positioning rod 42. During the movement of the connecting block 31, the corresponding baffle plate 3 is driven to move, so that the distance between the corresponding ends of the two baffle plates 3 is adjusted, thereby adjusting the width of the plastic granule movement channel, thereby realizing the regulation of the plastic granule flow rate;

[0039] Then the plastic particles enter the feed barrel 2 through the gap between the two baffle plates 3, and then the drive motor 22 is connected and started, so that the drive motor 22 drives the roller 21 to rotate, and then the multiple partitions 211 swing accordingly and move the plastic particles in the feed barrel 2, and then the plastic particles are guided by the feed barrel 2 and enter the plastic pellet machine;

[0040] During the feeding process, after the plastic particles at the bottom of the storage box 1 enter the feeding barrel 2, the plastic particles at the top are affected by gravity and move along the inclined surface of the inner wall at the bottom of the storage box 1 to be replenished, and then the number of plastic particles in the storage box 1 can be observed through the perspective plate 11.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
