It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Please refer to the following: Figures 1 to 4 The automatic flour feeding and screening device provided by this utility model will now be described. The automatic flour feeding and screening device includes a sieving machine 1, a feeding mechanism 2, a discharge pipe 3, a conveying paddle 4, a first discharge pipe 31, a second discharge pipe 32, and a cutting assembly 5. The output end of the feeding mechanism 2 is connected to the feed end of the sieving machine 1 and is used to feed flour to the sieving machine 1; the discharge pipe 3 is installed at the discharge end of the sieving machine 1 and is inclined upwards in a direction away from the sieving machine 1; the conveying paddle 4 is rotatably disposed inside the discharge pipe 3 and is used to push the flour away from the sieving machine 1; the first discharge pipe 31 is installed at the bottom of the discharge pipe 3 and is connected to the discharge pipe 3; the second discharge pipe 32 is installed at the bottom of the discharge pipe 3 and is connected to the discharge pipe 3, and is located on the side of the first discharge pipe 31 away from the sieving machine 1; the cutting assembly 5 is installed on the first discharge pipe 31 and is used to control the discharge state of the first discharge pipe 31.

[0032] Compared with the prior art, the automatic flour feeding and screening device provided in this embodiment includes a sieving machine 1 with a feeding mechanism 2 connected to its inlet. The feeding mechanism 2 automatically conveys flour into the sieving machine 1. A discharge pipe 3 is connected to the bottom of the sieving machine 1, and the discharge pipe 3 is inclined vertically. A first discharge pipe 31 and a second discharge pipe 32 are installed at the bottom of the discharge pipe 3, spaced apart along its length. A cutting component 5 is installed on the first discharge pipe 31 to control its flow. In use, flour is fed into the sieving machine 1 via the feeding mechanism 2, sieving the flour, and then discharged via the rotating conveying paddle 4 inside the discharge pipe 3. The second discharge pipe 32 is located at the inlet of the automatic dough mixer, and the feeding to the automatic dough mixer is completed by closing the first discharge pipe 31 via the cutting component 5. When it is necessary to send materials to other dough mixers, the first discharge pipe 31 can be opened to allow the flour to fall out from the first discharge pipe 31. The flour is then collected by the receiving bucket and transported to other dough mixers. This makes full use of the sieving machine 1, improves the utilization rate of the sieving machine 1, and thus improves production efficiency.

[0033] In some embodiments, the cutting component 5 may be employed as follows: Figure 2 The structure shown. See also Figure 2The cutting assembly 5 includes a flange plate 51 and an insert plate 52. There are two flange plates 51, which are installed parallel to each other along the axis of the first discharge pipe 31 on its outer side. The insert plate 52 is inserted between the two flange plates 51, and a socket for avoiding the insert plate 52 is provided in the middle of the first discharge pipe 31. Two flange plates 51 are installed in the middle of the first discharge pipe 31, both on its outer side. The two flange plates 51 are bolted together. Sockets for avoiding the insert plate 52 are provided between the two flange plates 51 and on the first discharge pipe 31, and the insert plate 52 slides freely inside the socket. By inserting the insert plate 52 into the socket, the first discharge pipe 31 can be blocked. By removing the insert plate 52, the first discharge pipe 31 can be opened, allowing flour to fall from the first discharge pipe 31. The structure is simple and the operation is convenient.

[0034] Preferably, in this embodiment, the first discharge pipe 31 includes two separate pipe bodies, each of which is fixedly connected to a flange plate 51. Grooves are provided on opposite sides of the two flange plates 51, and when the two flange plates 51 are joined together, the two grooves form a slot for installing the insert plate 52.

[0035] In some embodiments, the feeding mechanism 2 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The feeding mechanism 2 includes a storage bin 21 and a vacuum suction assembly 22. The inlet end of the vacuum suction assembly 22 is connected to the bottom end of the storage bin 21, and the outlet end is connected to the inlet end of the screening machine 1. An outlet pipe 211 is provided at the bottom of the storage bin 21, and the inlet pipe of the vacuum suction assembly 22 is connected to the outlet pipe 211 of the storage bin 21. Furthermore, the outlet end of the vacuum suction assembly 22 is located above the screening machine 1 and is connected to the inlet end of the screening machine 1. In use, flour can be placed inside the storage bin 21 first, and then the vacuum suction assembly 22 can be used to suck the flour into the screening machine 1, enabling automatic feeding of the screening machine 1 according to production conditions and reducing the labor requirements of operators.

[0036] Specifically, in this embodiment, the specific structure of the vacuum suction assembly 22 adopts existing technology, and will not be described here.

[0037] In some embodiments, the vacuum suction assembly 22 described above can be employed as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The bottom of the storage silo 21 is connected to a discharge pipe 211, and the top of the discharge pipe 211 is connected to an air inlet pipe 212. The air inlet pipe 212 is inclined from bottom to top away from the storage silo 21, and the top of the air inlet pipe 212 is connected to a filter element 213. After flour is added into the storage silo 21, the flour will fall into the discharge pipe 211 under its own weight and be conveyed into the screening machine 1 by the suction action of the vacuum suction component 22. The air inlet pipe 212 connected above the discharge pipe 211, and the filter element 213 installed on the air inlet pipe 212, can prevent the vacuum phenomenon inside the discharge pipe 211 during the suction process, which would cause the flour to be unstablely pumped into the screening machine 1. This improves the stability of the feeding process.

[0038] Specifically, in this embodiment, a control valve for controlling the flow state of the air intake pipe 212 is also installed on the air intake pipe 212.

See also Figure 3 The middle part of the discharge pipe 211 is connected to the bottom of the storage silo 21, and one end of the discharge pipe 211 is connected to an air blowing pipe 214. The air blowing pipe 214 and the air inlet pipe 212 are located on opposite sides of the storage silo 21. The air blowing pipe 214 is installed at the end of the discharge pipe 211 away from the end connected to the vacuum suction component 22, and the air blowing pipe 214 is connected to the inside of the discharge pipe 211. After the flour inside the storage silo 21 is completely sucked out, the air blowing pipe 214 can be opened to blow the flour on the inner wall of the discharge pipe 211 off and suck it to the screening machine 1 through the vacuum suction component 22. This can avoid flour residue inside the discharge pipe 211 and improve the utilization rate of flour.

[0040] In some embodiments, the feeding mechanism 2 described above may employ, for example... Figure 1 , Figure 4 The structure shown. See also...

The mounting frame 6 is installed on the ground, and the vacuum suction assembly 22 is mounted on the mounting frame 6. The vacuum suction assembly 22 has a degree of freedom in vertical adjustment on the mounting frame 6, so that when the screening machine 1 removes the screened impurities, the vacuum suction assembly 22 can be moved upward to maintain a certain distance between the vacuum suction assembly 22 and the screening machine 1, making it convenient for the operator to remove the impurities inside the screening machine 1.

[0041] Preferably, in this embodiment, a telescopic tube is provided between the discharge end of the vacuum suction assembly 22 and the feed inlet of the screening machine 1, so that the discharge end of the vacuum suction assembly 22 and the feed inlet of the screening machine 1 can always be kept in communication when the vacuum suction assembly 22 moves up and down.

The trolley 62 is slidably mounted on the column 61, and the vacuum suction assembly 22 is fixedly mounted on the trolley 62. A pull rope 63 is also installed on the top of the column 61, with one end fixedly mounted on the trolley 62, thus preventing the trolley 62 from moving downward and ensuring the height stability of the vacuum suction assembly 22.

[0043] In some embodiments, the trolley 62 described above may employ, for example... Figure 4 The structure shown. See also Figure 4 A fixed shaft is fixedly installed on one side of the trolley 62, and rollers 621 are rotatably mounted on both ends of the fixed shaft. The rollers 621 are rolled on the column 61. One end of the pull rope 63 is detachably mounted on the fixed shaft. Rollers 621 for rolling on the outside of the column 61 are rotatably mounted on the trolley 62. Multiple rollers 621 are arranged in pairs, and a fixed shaft is provided between two rollers 621. The rollers 621 are rotatably mounted on the fixed shaft. One end of the pull rope 63 is tied and fixed to the fixed shaft. The structure is simple and facilitates fixing the pull rope 63 to the trolley 62.

[0044] Preferably, in this embodiment, a drive disc is rotatably mounted on the top of the column 61, one end of the pull rope 63 is wound around the outside of the drive disc, and a pin for limiting the rotation of the drive disc is slidably mounted on the column 61.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
