DETAILED DESCRIPTION

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments: Example 1

[0029] like Figure 1-5 As shown, the utility model provides a flour screening device for flour production, including an outer frame 1, a screening mechanism 2 and a swing driving mechanism 3, the inner wall of the screening mechanism 2 is fixedly connected with a built-in screen 7, and the screening mechanism 2 is located on both sides above the built-in screen 7 and is arranged on a slag discharge sealing assembly.

[0030] The slag discharge sealing assembly includes a closed slag discharge plate 8 that is rotatably fitted to the side of the screening mechanism 2, a traction line 6 that is fixedly connected to the corner of the closed slag discharge plate 8, a reset spring 11 for providing a reset force to the closed slag discharge plate 8, and a positioning column 10 for hanging the reset spring 11.

[0031] A side-opened slag discharge groove 9 for slag discharge is opened on the side of the screening mechanism 2, and a sealing bonding plate 12 is fixedly connected to the side of the closed slag discharge plate 8 close to the outer frame 1. The outer wall of the sealing bonding plate 12 is movably connected to the inner wall of the side-opened slag discharge groove 9, and a material guide cloth cylinder 15 is fixedly connected to the bottom surface of the screening mechanism 2.

[0032] A side mounting block 13 for mounting the return spring 11 is fixedly connected to the side of the closed slag discharge plate 8 , and one side of the side mounting block 13 is fixedly connected to one end of the return spring 11 .

[0033] One end of the traction line 6 away from the closed slag discharge plate 8 is fixedly connected to the inner wall of the outer frame 1. When the side-opening slag discharge groove 9 is closed, the swing drive mechanism 3 drives the screening mechanism 2 to deflect left and right within a suitable angle range, and will not drive the traction line 6 to generate tension on the closed slag discharge plate 8. At this time, the traction line 6 is in a relaxed state, which ensures the sealing effect of the side-opening slag discharge groove 9 while also ensuring the normal flour screening.

[0034] While the screening mechanism 2 is swinging left and right, the material guiding cloth tube 15 is stretched or contracted accordingly, so as to always keep the restriction and guiding effect on the flour.

[0035] As for the pulling effect of the traction line 6, the winding motor of the outer wall of the traction line 6 can also be controlled. When the traction line 6 needs to be pulled, it is wound up, otherwise it is kept in the original state or unwound. Example 2

[0036] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the bottom end of the material guide cloth cylinder 15 is fixedly connected to the bottom of the inner wall of the outer frame 1. The outer frame 1 is fixedly connected with a material guide cloth cylinder 14 for lowering and collecting hoppers that communicate with the material guide cloth cylinder 15.

[0037] A slag discharge net 4 is fixedly connected to the bottom of the inner wall of the outer frame 1 , and a collecting box 5 in communication with the slag discharge net 4 is fixedly connected to the bottom surface of the outer frame 1 .

[0038] The bottom surface of the outer frame 1 is fixedly connected with a supporting leg.

[0039] The working principle of the flour screening device for flour production is described in detail below.

[0040] like Figure 1-5 As shown, during use, when it is necessary to remove the impurities filtered by the built-in screen 7, the swing drive mechanism 3 is started, so that when the swing drive mechanism 3 uses the belt to deflect the screening mechanism 2 to the maximum deflection angle, the traction line 6 just pulls the closed slag discharge plate 8, so that the closed slag discharge plate 8 rotates to a state nearly parallel to the built-in screen 7. At this time, since the screening mechanism 2 is in a deflected state, the built-in screen 7 is deflected synchronously. At this time, the impurities on the surface of the built-in screen 7 will gradually move to the position of the side-opening slag discharge groove 9 under the action of gravity. When the side-opening slag discharge groove 9 is opened, the impurities will be discharged into the outer frame 1 along the closed slag discharge plate 8, and then fall into the collection box 5 through the slag discharge net 4 for temporary storage.

[0041] When the swing drive mechanism 3 drives the screening mechanism 2 to reset, the tension on the reset spring 11 gradually decreases. When the screening mechanism 2 moves to the traction line 6 and is no longer pulled straight by the closed slag discharge plate 8, the reset spring 11 will drive the closed slag discharge plate 8 to reset and gradually close the side-opening slag discharge groove 9.

[0042] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the utility model. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
