[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0032] Example 1: A curved feeding mechanism for roller-pressed raw meal preparation, see Figures 1 to 4 , including a roller press body 1, a material lowering bin 2, a material feeding bin 3 and a material guiding structure 4;

[0033] The lower material bin 2 is fixedly arranged at the feeding end of the roller press body 1; the feeding bin 3 is fixedly arranged at the top of the lower material bin 2; wherein the lower material bin 2 is connected with the feeding bin 3; two material guide structures 4 are respectively arranged at both sides of the lower material bin 2;

[0034] The material guiding structure 4 includes an L-shaped plate 401, a U-shaped plate 402 and an arc-shaped plate 403;

[0035] The horizontal section of the L-shaped plate 401 is arranged on the side of the lower hopper 2; the opening of the U-shaped plate 402 is snap-fitted with the vertical section of the L-shaped plate 401; the top of the arc-shaped plate 403 is fixedly connected to the inner side of the opening end of the U-shaped plate 402, the two arc-shaped plates 403 are relatively inclined, and the opening formed by the bottom ends of the two arc-shaped plates 403 corresponds to the two grinding rollers in the roller press body 1.

[0036] The utility model has the advantage of centrally gathering the falling raw materials before entering the roller press body 1 by arranging the L-shaped plate 401, the U-shaped plate 402 and the arc-shaped plate 403, so that the raw materials enter between the two grinding rollers in the roller press body 1 for processing, thereby solving the problem that the raw materials entering the roller press cannot enter between the two grinding rollers in time due to the lack of material guidance for the poured raw materials.

[0037] Specifically, the horizontal section of the L-shaped plate 401 is passed through the through hole 201 opened on the side of the lower material bin 2, and a connecting plate 404 is fixedly provided at the horizontal end of the L-shaped plate 401. Two telescopic rod bodies 407 are symmetrically arranged between the inner side of the connecting plate 404 and the side of the lower material bin 2. The telescopic rod body 407 includes an inner rod and a sleeve. One end of the inner rod is fixedly connected to the side of the lower material bin 2, one end of the sleeve is fixedly connected to the inner side of the connecting plate 404, and the other end of the inner rod is movably connected to the other end of the sleeve; springs 408 are both sleeved on the two telescopic rod bodies 407, and both ends of the spring 408 are respectively fixedly connected to the inner side of the connecting plate 404 and the side of the lower material bin 2, and the elastic coefficient of the spring 408 is selected and used by technical personnel in this profession according to actual conditions.

[0038] The utility model has the advantage of driving the L-shaped plate 401 to move horizontally by setting a connecting plate 404, a telescopic rod body 407 and a spring 408, so that the vertical section of the L-shaped plate 401 can leave the inner wall of the lower material bin 2, making it easier for the U-shaped plate 402 to dock with the vertical section of the L-shaped plate 401 in a larger space, thereby facilitating the installation or removal of the arc plate 403.

[0039] Furthermore, a handle 405 is fixedly provided on the outer side of the connecting plate 404, and the connecting plate 404 can be easily moved by the handle 405.

[0040] Furthermore, a material guide bar 406 is fixedly provided at the top of the U-shaped plate 402. The material guide bar 406 adopts a triangular structure design, and the inclined surface of the material guide bar 406 faces inwards.

[0041] The utility model provides a material guide strip 406 having a triangular structure so that the falling raw materials can slide along the inclined surface when they contact the inclined surface, thereby reducing the obstruction to the falling raw materials.

[0042] It is worth noting that the outer side of the U-shaped plate 402 contacts and cooperates with the inner side wall of the lower material bin 2, wherein the outer side of the U-shaped plate 402 is aligned with the outer side of the guide bar 406. Under the push of the compressed spring 408, the vertical section of the L-shaped plate 401 pushes the U-shaped plate 402 against the inner side wall of the lower material bin 2, thereby keeping the arc plate 403 stable.

[0043] Working principle: using the device of the utility model, the raw material enters from the feed bin 3 and passes through the discharge bin 2. When the raw material passes through the two arc plates 403, the falling raw material is gathered in the center, so that the raw material enters between the two grinding rollers in the roller press body 1 for processing. According to the degree of wear of the curved plate 403, when it is replaced due to excessive wear, the connecting plate 404 is pushed inwardly by the handle 405, the telescopic rod body 407 is shortened, the spring 408 is further compressed, the horizontal section of the L-shaped plate 401 moves inward relative to the side of the lower material bin 2, and the vertical section of the L-shaped plate 401 moves accordingly, and the U-shaped plate 402 no longer presses against the inner wall of the lower material bin 2. The U-shaped plate 402 and the curved plate 403 are taken out, and the new U-shaped plate 402 and the curved plate 403 are put into the lower material bin 2. The opening of the U-shaped plate 402 is engaged with the vertical section of the L-shaped plate 401, and the handle 405 is released. Under the push of the elastic force of the spring 408, the horizontal section of the L-shaped plate 401 moves outward relative to the side of the lower material bin 2, and the vertical section of the L-shaped plate 401 moves accordingly until the U-shaped plate 402 presses against the inner wall of the lower material bin 2, and the curved plate 403 can be continued to be used after replacement.

[0044] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
