[0019] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0020] Example 1

[0021] like Figures 1-3 As shown, this utility model provides a raw material feeding device, including a feeding cylinder 1; a discharge port is provided at the bottom of the feeding cylinder 1, and an inlet 6 and an outlet 7 are correspondingly provided on the side wall of the feeding cylinder 1. A first conveyor belt 3 is provided at the inlet 6, and the discharge end of the first conveyor belt 3 extends into the feeding cylinder 1 from the inlet 6. A second conveyor belt 4 is provided at the outlet 7. The feeding cylinder 1 is also equipped with a transmission chain 5, which enters the feeding cylinder 1 from the inlet 6 and extends out from the outlet 7. The transmission chain 5 is located above the first conveyor belt 3 and the second conveyor belt 4. A plurality of connecting rods 8 are evenly provided on the transmission chain 5, and a pulling member 9 is provided at the lower end of the connecting rod 8.

[0022] The feeding cylinder 1 corresponding to the discharge end of the conveyor belt 3 is equipped with a packing knife 10. The packing knife 10 is fixedly connected to the inner wall of the feeding cylinder 1 by a fixing rod 12. The upper end of the packing knife 10 is higher than the conveying surface of the conveyor belt 3.

[0023] The prying component 9 is a finger cylinder. The finger cylinder clamps and holds one end of the material package 11 in place.

[0024] The packing component 9 is hinged to the lower end of the connecting rod 8 via a rotating shaft 13. This configuration allows for greater flexibility when the packing component 9 fixes the material pack 11 within the conveyor belt 3, conveyor belt 4, and feeding cylinder 1.

[0025] The fixed rod 12 has a trapezoidal cross-section. This design allows materials falling on the fixed rod 12 to slide more smoothly into the feeding cylinder 1, preventing material accumulation on the fixed rod 12.

[0026] The top of the feeding cylinder 1 is equipped with an exhaust pipe 2. The exhaust pipe 2 can be connected to a dust collector (cyclone separator) to facilitate the recovery of material dust generated during the feeding process, thereby reducing environmental pollution and material waste.

[0027] Working principle: The feeding cylinder is connected to the inlet of the reaction tank. The material to be fed is placed sequentially on the conveyor belt 3. The material bag 11 is loaded inside the material bag 11. One end of the material bag 11 is fixed by the corresponding bag-pulling component 9 on the transmission chain 5. The transmission chain 5 moves synchronously with the conveyor belt 3. The material bag 11 is transported to the feeding cylinder 1. When it passes the bag-breaking knife 10, the bag-breaking knife 10 cuts open the material bag 11, and the material leaks out from the material bag 11 and spills into the feeding cylinder 1. The material scattered on the conveyor belt 3 also enters the feeding cylinder 1 through the discharge end of the conveyor belt. The empty bag 14 is suspended on the bag-pulling component 9 and transported out from the outlet 7. When the empty bag 14 is transported above the second conveyor belt 4, the bag-pulling component 9 is released from fixing the empty bag 14. The empty bag 14 falls on the second conveyor belt 4 and is sent away for further processing. In this way, continuous and efficient feeding operations can be carried out.

[0028] Example 2

[0029] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the pull-out component 9 is a hook 15. The hook 15 holds one end of the material package 11.

[0030] The materials to be fed are placed sequentially on conveyor belt 3. Material bags 11 are loaded inside the material bags 11. One end of the material bags 11 is fixed by the corresponding bag-pulling component 9 on the drive chain 5. The drive chain 5 moves synchronously with conveyor belt 3. The material bags 11 are transported to the feeding cylinder 1. When passing the bag-breaking knife 10, the bag-breaking knife 10 cuts open the material bags 11, and the material leaks out from the material bags 11 and spills into the feeding cylinder 1. The material scattered on conveyor belt 3 also enters the feeding cylinder 1 through the discharge end of the conveyor belt. The empty bags 14 are suspended on the bag-pulling component 9 and transported out from the outlet 7. When the empty bags 14 are transported above conveyor belt 4, the empty bags are manually removed from the hooks 15. The empty bags 14 fall on conveyor belt 4 and are sent away for further processing. In this way, continuous and efficient feeding operations can be carried out.

[0031] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
