A limit seat 601 is installed at the bottom of the inner part of the grinding mill body 1, and a screening screen 602 is slidably connected inside the limit seat 601, and a spring 603 is connected to the top of the screening screen 602. A fixed motor 604 is connected to one side of the outer wall of the grinding mill body 1 through a protective box; a guide cam 606 is connected to the output end of the fixed motor 604 ... The guide column 605 is provided with a bevel gear A606 on its outer wall; the bevel gear A606 is meshed with a bevel gear B607 on its outer wall, and a rotating rod 608 is connected to the inside of the bevel gear B607, and the rotating rod 608 is connected to the grinding mill body 1 through a bearing seat on the side away from the bevel gear B607; eccentric cams 609 are sleeved on both sides of the outer wall of the rotating rod 608, a rotating disk 610 is welded to the bottom end of the guide column 605, and the bottom end of the rotating disk 610 is rotatably connected to a transmission rod 611 through a fixing pin; the transmission rod 611 is away from the bevel gear B607. A guide plate 612 is connected to one side of the rotating disk 610, and support seats 613 are slidably connected to both sides of the outer wall of the guide plate 612, and the top of the support seat 613 is welded to the grinding machine body 1; a guide hole corresponding to the discharge pipe 5 is opened inside the guide plate 612, the spring 603 is connected to the limit seat 601, the outer wall of the eccentric cam 609 is connected to the screening screen 602, the limit seat 601, the screening screen 602 and the spring 603 form an elastic telescopic mechanism, and the transmission rod 611 and the guide plate 612 are rotatably connected.

[0027] In specific implementation, when a flour mill is needed to assist in the flour processing, in order to prevent larger particles from appearing inside the product, when the ground powder needs to be screened, the product is first screened through a screening screen 602 to block larger particles and prevent a high defect rate of the product. During the flour grinding process, the fineness, color and taste of the flour will be affected by the operating state of the flour mill. In order to reduce the workload of the equipment and improve the production quality, the fixed motor 604 is started in advance to drive the guide column 605 to rotate, and then the guide column 605 rotates to drive the rotating disk 610 to rotate. Since the rotating disk 610 is rotatably connected to the transmission rod 611, the transmission rod 611 rotates when the rotating disk 610 rotates.

[0028] At this time, the angle between the transmission rod 611 and the guide plate 612 changes, thereby generating a pulling force for the guide plate 612 to move back and forth, and then the guide plate 612 reciprocates along the support seat 613, so that the product discharged from the discharge pipe 5 intermittently passes through the guide hole on the guide plate 612, so that the mill body 1 can discharge intermittently to relieve the burden of the equipment, and prevent the mill body 1 from working continuously with a heavy burden and affecting the quality of the product;

[0029] Because the guide column 605 is connected to the bevel gear A606, the guide column 605 rotates to drive the bevel gear A606 to rotate together, and because the bevel gear A606 is meshed with the bevel gear B607, the bevel gear A606 rotates to drive the bevel gear B607 to rotate, and then the bevel gear B607 rotates to drive the rotating rod 608 to rotate, and because the outer wall of the rotating rod 608 is connected to the eccentric cam 609, the rotating rod 608 rotates to drive the eccentric cam 609 to rotate together, and then the eccentric cam 609 rotates to squeeze the screening screen 602, generating an upward thrust on the screening screen 602, so that the screening screen 602 moves up along the limit seat 601 to squeeze the spring 603, causing the spring 603 to deform;

[0030] When the eccentric cam 609 rotates and is disconnected from the screening screen 602, the spring 603 returns to its original position and generates elastic force, causing the screening screen 602 to collide with the limit seat 601 repeatedly, thereby shaking off the particles that cause the screening screen 602 to be blocked, preventing the screening screen 602 from being blocked and affecting the filtering effect, thereby having the functions of screening and preventing blockage and improving production quality when the grinding mill is used.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 8It can be seen that the outer wall of the feed pipe 2 is provided with a stirring mechanism 7, and the stirring mechanism 7 includes a double-shaft motor 701, a stirring rod A702, a synchronous wheel A703, a synchronous belt 704, a synchronous wheel B705, a first gear 706, a second gear 707 and a stirring rod B708. The double-shaft motor 701 is installed on one side of the top of the grinding mill body 1; the stirring rod A702 is connected to the bottom output end of the double-shaft motor 701, and the synchronous wheel A703 is connected to the top output end of the double-shaft motor 701, and The synchronous wheel A703 is connected to the synchronous wheel B705 through the synchronous belt 704; the interior of the synchronous wheel B705 is connected to the first gear 706 through a rotating column, and the outer wall of the first gear 706 is meshed with the second gear 707, and the interior of the second gear 707 is docked with a stirring rod B708; the bottom end of the rotating column is connected to the grinding mill body 1 through a bearing seat, the outer wall of the synchronous wheel B705 is connected to the synchronous belt 704, and the stirring rod A702 and the stirring rod B708 ​​are parallel to each other.

[0032] In specific implementation, during the flour processing, when a flour mill is needed to assist, in order to prevent the raw materials from agglomerating and affecting the subsequent grinding work, when the raw materials need to be broken up and made loose, the fixed motor 604 is first started to rotate forward. Since the output end of the fixed motor 604 is connected to the stirring rod A702 and the synchronous wheel A703, the fixed motor 604 is started to drive the stirring rod A702 and the synchronous wheel A703 to rotate forward, and since the synchronous wheel A703 is connected to the synchronous wheel B705 through the synchronous belt 704, the synchronous wheel A703 rotates and drives the synchronous wheel B705 to rotate forward through the synchronous belt 704, and then the synchronous wheel B705 drives the first gear 706 to rotate forward through the rotating column, and since the first gear 706 is meshed with the second gear 707, the first gear 706 rotates forward to drive the second gear 707 to rotate reversely, and then the second gear 707 drives the stirring rod B708 ​​to rotate reversely;

[0033] A relative rotation mechanism is then formed above the grinding roller 4, which stirs and breaks up the incoming raw materials, making the raw materials loose and convenient for grinding by the grinding roller 4, thereby facilitating the breaking up of the raw materials when the mill is used.

[0034] To sum up, when the mill with screening function is used, the raw material is first introduced into the mill body 1 through the feed pipe 2, and then the grinding motor 3 is started to drive the grinding roller 4 to rotate, so that the grinding roller 4 grinds the raw material until the raw material is ground into powder and discharged from the discharge pipe 5 through the mill. This is the prior art and will not be elaborated on here. The product is screened by the auxiliary mechanism 6 to prevent the product from having a high defect rate, and the mill body 1 is allowed to perform intermittent discharge to relieve the burden of the equipment, to prevent the mill body 1 from working continuously and having a heavy burden that affects the quality of the product, and to prevent the screening screen 602 from being blocked and affecting the filtering effect. A relative rotation mechanism is formed above the grinding roller 4 through the stirring mechanism 7, and then the incoming raw material is stirred and dispersed, so that the raw material becomes loose and convenient for the grinding roller 4 to grind. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
