[0029] The specific implementation process of this utility model device in the production process is as follows: First, adjust the position of the two package-breaking blades 3 on the blade fixing frame 5, and then start the device. The front-end robot handling and gripping device grabs the raw material package 6 and places it between the two limiting plates 7 on the package fixing and tapping mechanism mounting frame 11. Then, the limiting and fixing cylinders 1 on the left and right sides work simultaneously, respectively driving the limiting and fixing plates 8 on the left and right sides to move and fix the two sides of the raw material package 6. Next, the piercing cylinder 9 works to drive the pointed piercing rod 18 forward to pierce into the raw material package 6 for secondary fixation. Then, the movable rod of the flipping cylinder 12 extends, driving the package fixing and tapping mechanism mounting frame 11 to flip around the two flipping bearings 13 as the center, finally making it perpendicular to the ground. Next, the bag-breaking cylinder 15 operates, driving the bag-breaking movable frame 25 and its upper components to move together. During this movement, the two bag-breaking blades 3 cut two slits at the bottom of the raw material bag 6, allowing plastic raw material granules to exit through the slits and fall into the receiving hopper 4. Simultaneously, the rear raw material feeding system transports the raw material in the receiving hopper 4 to various extruders and injection molding machines for extrusion production. After the raw material in the raw material bag 6 is completely released, the tapping cylinder 10 operates, driving the tapping rod 24 to repeatedly tap the empty raw material bag 6 several times to release any remaining plastic raw material granules. Then, the tilting cylinder 12 drives the bag-fixing tapping mechanism mounting frame 11 to return to its original position. Next, the piercing cylinder 9 drives the pointed piercing rod 18 to return to its original position, while the two side limiting and fixing cylinders 1 drive the two side limiting and fixing plates 8 to return to their original positions. At the same time, the bag-breaking cylinder 15 drives the bag-breaking movable frame 25 and its upper components to return to their original positions. Finally, the front-end robot handling and grasping device grabs the empty raw material package 6 and stores it. Then, it transports the new raw material package and places it on the material package fixing and tapping mechanism mounting frame 11 to perform the process of fixing, flipping, breaking the package and tapping to clean the material again. This process is repeated.

[0030] In this invention, the pack-breaking slider and pack-breaking rail guide the forward and backward movement of the pack-breaking frame, ensuring its stability and smoothness, thereby improving the stability of raw material pack breaking. The blade fixing frame adopts an adjustable design, and the position of the two pack-breaking blades can be adjusted through the oblong hole, thereby improving the accuracy and reliability of raw material pack breaking. The limiting fixing plates on both sides can limit and fix the raw material package, thus providing a stable connection for subsequent piercing, fixing, and flipping. The pointed piercing rod can provide secondary fixation for the raw material package. The tapping rod can tap the empty raw material package after the raw material is released to further discharge the residual raw material particles inside, thereby achieving material cleaning.
