[0082] Among them, the rotation groove 18 is fan-shaped;

[0083] The limiting block 17 is fixedly connected to the outer surface of the second fixed shaft 11;

[0084] Among them, the limiting block 17 is slidably connected to the rotating groove 18;

[0085] The outer surface of the loading bucket 15 contacts and is slidably connected to the front surface of the inclined conveying plate 7 .

[0086] Furthermore, a plastic processing barrel, a buckle connection block, a locking buckle, a movable roller, a brake plate, etc. are installed on the base 1. The plastic processing barrel, the buckle connection block, the locking buckle, the movable roller, the brake plate, etc. are existing technologies in the existing public patent: CN202120770067.9 A feeding device for plastic product processing, which will not be described in detail here;

[0087] Furthermore, the rear side of the inclined conveying plate 7 extends into the plastic processing barrel.

[0088] Furthermore, in the initial state, the loading barrel 15 is in a vertical state. After the thermoplastic plastic is loaded into the loading barrel 15, the motor 6 is started. The motor 6 starts to drive the threaded rod 21 on the left to rotate. Driven by the chain 23 and the sprocket 22, the two threaded rods 21 rotate synchronously. The rotation of the two threaded rods 21 drives the two sliding blocks 9 to move back and forth, and then synchronously drives the loading barrel 15 to move back and forth. During the backward movement of the loading barrel 15, its outer surface contacts the front side surface of the inclined conveying plate 7, and as the loading barrel 15 moves backward, the inclined conveying plate 7 gives the loading barrel 15 a thrust, pushing the loading barrel 15 to move along the first fixed axis. 10 is rotated as the center, thereby also driving the limiting block 17 to rotate synchronously in the limiting groove 16. In this process, the mainspring 20 is driven to shrink and deform, and the loading barrel 15 is tilted during its rotation. During the tilting process of the loading barrel 15, the thermoplastic plastic in the loading barrel 15 is poured onto the inclined conveying plate 7, and then transported into the plastic processing barrel by the inclined conveying plate 7, thereby realizing the loading of the thermoplastic plastic. The pouring of the loading barrel 15 can be completed by using only one motor, which saves electricity and can reduce the economic cost of the loading device, thereby increasing the energy saving and practicality of the loading device, and thereby reducing the production cost of thermoplastic products.

[0089] As mentioned above, when the limiting block 17 rotates to the limit, the rotation angle of the loading bucket 15 can pour out all the thermoplastic plastic therein. After the thermoplastic plastic in the loading bucket 15 is poured out, the starting motor 6 drives the loading bucket 15 to move downward. At this time, the loading bucket 15 also moves forward without contacting the inclined conveying plate 7, and under the action of the released elastic force of the spring 20, the loading bucket 15 is driven to return to a vertical state. The elastic force of the spring 20 in this solution is relatively large, ensuring that the loading bucket 15 will not shake during the up and down movement after it is filled with thermoplastic plastic, and can also make the initial state of the loading bucket 15 vertical, avoiding the loading bucket 15 from shaking during the loading process, thereby ensuring the loading stability of the loading bucket 15 while increasing the practicality of the loading bucket 15.

[0090] As described above, when the limiting block 17 is slidably connected to the limiting groove 16 to limit the rotation angle of the loading barrel 15, it can prevent the thermoplastic plastic in the loading barrel 15 from spilling out due to excessive rotation angle of the loading barrel 15, thereby increasing the practicality of the loading device.

[0091] Furthermore, in this solution, the tension between the chain 23 and the sprocket 22 is relatively large.

[0092] Working principle: When the device is used, in the initial state, the loading barrel 15 is in a vertical state. After the thermoplastic plastic is loaded into the loading barrel 15, the motor 6 is started. The motor 6 starts to drive the threaded rod 21 on the left to rotate. Driven by the chain 23 and the sprocket 22, the two threaded rods 21 rotate synchronously. The rotation of the two threaded rods 21 drives the two sliding blocks 9 to move back and forth, and then synchronously drives the loading barrel 15 to move back and forth. During the backward movement of the loading barrel 15, its outer surface contacts the front surface of the inclined conveying plate 7, and as the loading barrel 15 moves backward, the inclined conveying plate 7 gives the loading barrel 15 a thrust, pushing the loading barrel 15 to The first fixed shaft 10 rotates with the first fixed shaft 10 as the center, thereby driving the limiting block 17 to rotate synchronously in the limiting groove 16. In this process, the mainspring 20 is driven to shrink and deform, and the loading barrel 15 is tilted during its rotation. During the tilting process of the loading barrel 15, the thermoplastic plastic in the loading barrel 15 is poured onto the inclined conveyor plate 7, and then transported into the plastic processing barrel by the inclined conveyor plate 7, thereby realizing the loading of the thermoplastic plastic. The dumping of the loading barrel 15 can be completed using only one motor, which saves electricity and can reduce the economic cost of the loading device, thereby increasing the energy saving and practicality of the loading device, thereby reducing the production cost of thermoplastic plastic products.
