[0002] Noodle products are a major part of Chinese cuisine and have a long history. Common noodle products mainly include steamed buns, twisted rolls, etc. In ordinary families, noodle products are usually made by hand. However, with the development of technology and the improvement of automation level, automatic noodle production equipment has emerged and is applied in central kitchens to achieve rapid large-scale production of noodle products.

[0003] When existing automatic noodle production equipment produces noodle products, usually formed noodle dough pieces are conveyed by a conveyor belt to a proofing tray, and then the proofing tray is transported to a proofing room for proofing, and finally the proofed noodle dough pieces are steamed. Since the noodle dough pieces contain a certain amount of moisture, when the conveyor belt conveys the noodle dough pieces, the noodle dough pieces are likely to adhere to the conveyor belt, thus affecting the conveying efficiency of the noodle dough pieces and the shape of the noodle products; at the same time, the noodle dough pieces adhering to the conveyor belt cannot be automatically removed, so staff need to clean the conveyor belt regularly. In addition, over time, the moisture of the noodle dough pieces adhering to the conveyor belt is gradually completely evaporated, resulting in the noodle dough pieces adhering to the conveyor belt separating from the conveyor belt and adhering to new noodle dough pieces, thereby affecting the production quality of the noodle products. Summary of the Utility Model

[0046] Referring to Figures 1 to 8 , a conveying device for pasta production is disclosed, which includes a conveying frame 1, a driving roller 2 rotatably connected to the conveying frame 1, a driven roller 3 rotatably connected to the conveying frame 1, and a belt body 4 sleeved outside the driving roller 2 and the driven roller 3. A flour box 5 is provided at the top of the conveying frame 1. The flour box 5 has a powder spreading port 511 facing the belt body 4. A powder spreading roller 6 is provided in the flour box 5 at the powder spreading port 511. The powder spreading roller 6 can rotate following the driving roller 2 or the driven roller 3. When the belt body 4 rotates, the powder spreading roller 6 spreads the flour in the flour box 5 onto the surface of the belt body 4 through the powder spreading port 511. A scraping plate 7 is provided on the conveying frame 1 at the bottom of the belt body 4, and the scraping plate 7 abuts against the belt body 4.

[0047] It can be understood that the flour box 5 is located directly above the belt body 4 so that the powder spreading port 511 faces the belt body 4 directly, ensuring the powder spreading effect on the belt body 4.

[0048] Before using the conveying device in this application to convey pasta dough pieces, first pour the flour into the flour box 5. When conveying the pasta dough pieces, the belt body 4 rotates under the action of the driving roller 2, and the driven roller 3 rotates under the action of the belt body 4. At this time, the powder spreading roller 6 rotates under the action of the driving roller 2 or the driven roller 3, and then the flour in the flour box 5 falls onto the belt body 4 under the action of the powder spreading roller 6 through the powder spreading port 511, so as to avoid the situation that the pasta dough pieces adhere to the belt body 4, thereby ensuring the conveying efficiency of the pasta dough pieces and ensuring the shape of the pasta dough pieces.

[0049] At the same time, since the scraping plate 7 abuts against the belt body 4, the scraping plate 7 then scrapes the pasta dough pieces adhered to the belt body 4 to avoid the situation that the moisture of the pasta dough pieces is completely evaporated and then adheres to the new pasta dough pieces, thereby ensuring the production quality of the pasta and improving the quality stability of the pasta.

[0050] Furthermore, the powdering roller 6 can also generate vibration when rotating to vibrate the flour in the flour box 5, so that the flour in the flour box 5 moves downward and contacts the powdering roller 6, so as to ensure the powdering effect on the belt body 4.

Preferably, refer to Figure 3 The powdering roller 6 has a receiving groove 61 , and a plurality of receiving grooves 61 are arranged at intervals along the circumference of the powdering roller 6 , and each receiving groove 61 is extended along the axial direction of the powdering roller 6 .

[0052] Specifically, after pouring flour into the flour box 5, part of the flour falls into the receiving groove 61, and then when the powdering roller 6 rotates under the action of the active roller 2 or the driven roller 3, the flour in the receiving groove 61 falls onto the belt body 4 through the powdering port 511, so that the flour is sprinkled onto the belt body 4.

[0053] In other embodiments, the powdering roller 6 may also be a roller-shaped structure with a textured surface, as long as the flour in the flour box 5 can be discharged through the powdering port 511 under the action of the powdering roller 6 when the powdering roller 6 rotates.

[0054] In a preferred embodiment, referring to Figure 3 The flour box 5 is provided with blocking plates 512 located on opposite sides of the powder sprinkling port 511. The two blocking plates 512 form a powder lowering channel. The powder sprinkling roller 6 is located in the powder lowering channel, so that the blocking plates 512 can block the flour in the flour box 5 to prevent the flour from flowing out through the side of the powder sprinkling port 511, thereby ensuring the uniformity of the flour sprinkling and avoiding the waste of flour.

[0055] In addition, by setting the blocking plate 512, the external shape of the flour box 5 can be made more regular, which can reduce the production difficulty of the flour box 5 on the one hand, and increase the connection stability between the flour box 5 and the conveying frame 1 on the other hand.

[0056] Further, see Figure 3 Each blocking plate 512 includes a vertical section and a guide section. The two vertical sections form a flour discharge channel. The two guide sections are inclined from bottom to top in directions away from each other and the top ends are connected to the inner wall of the flour box 5, so that the guide sections can guide the flour in the flour box 5 so that the flour in the flour box 5 can be discharged through the powder sprinkling port 511 under the action of the powder sprinkling roller 6, thereby avoiding the waste of flour and avoiding the occurrence of flour deterioration due to the accumulation of dead corners in the flour box 5, thereby further ensuring the production quality of pastries and product quality.
