CONCRETE EMBODIMENT
[0025] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0026] Please refer to Figures 1 to 7 , a material equalizing and knot removing assembly for a vibrating screening machine, comprising a guide mechanism 3 arranged at a discharge port 1 and used to guide the material to a middle position of the vibrating screening machine 2, a flow dividing member 4 arranged on the vibrating screening machine 2 and used to evenly spread the material at the middle position along the width direction of the vibrating screening machine 2, and a grid member 5 arranged on the vibrating screening machine 2 and used to limit the movement of the knot-shaped material to the feeding direction.
[0027] The application discloses a material uniformizing and lump removing assembly for a vibrating screening machine, which is characterized by the following technical scheme: a guide mechanism is arranged near the discharge port to ensure that the material can be accurately guided to the middle position of the vibrating screening machine, and then a flow dividing element is used to evenly spread the material at the middle position along the width direction of the vibrating screening machine, thereby effectively solving the problem of uneven distribution of tobacco leaves on the vibrating screening machine and fully exerting the screening effect of the screen hole. Meanwhile, a grid element is arranged on the vibrating screening machine to filter and limit the lumped material from moving to the next stage along the feeding direction, and the lumped material can be taken out manually, thereby improving the screening effect of the lumped tobacco leaves, making the vibrating screening machine more effectively clean out the debris and lumped tobacco leaves in the tobacco leaves, and improving the quality and efficiency of the material screening.
[0028] Further, as a preferred embodiment of the present application but not limited, the guide mechanism 3 comprises a prism rotating shaft 31, mounting plates 32 arranged on both sides of the discharge port 1, sliding grooves 33 arranged along the length direction of the mounting plates 32 and used for clamping both ends of the prism rotating shaft 31, and a guide plate assembly 34 sleeved on the prism rotating shaft 31, and fasteners are passed through both ends of the prism rotating shaft 31 to keep the prism rotating shaft 31 and the sliding grooves 33 fastened.
[0029] In the embodiment, the mounting plates are arranged on both sides of the discharge port, and the sliding grooves extending along the length direction of the mounting plates are arranged on the mounting plates, so that the prism rotating shaft can be clamped in the sliding grooves, thereby realizing the fixation and rotation of the prism rotating shaft. When the prism rotating shaft is loosened from the sliding grooves by the fasteners, the prism rotating shaft can rotate and slide to adjust the position and angle, and the guide plate assembly can move synchronously with the rotation of the prism rotating shaft; when the prism rotating shaft is fastened with the sliding grooves by the fasteners, the prism rotating shaft and the sliding grooves are kept in the fixed position. The design can flexibly adjust the angle and position of the guide plate assembly to adapt to different material flow directions of the discharge port, and can accurately guide the material to the middle position of the vibrating screening machine through the guide plate assembly, thereby avoiding uneven distribution of the material on the screening machine and affecting the screening effect. When the material falls from the discharge port, the operator can adjust the angle of the guide plate assembly in real time according to the falling condition of the material to guide the material to the middle of the vibrating screening machine. The guide plate assembly is detachable, so that different lengths of guide plates can be replaced according to different material flow sizes, thereby improving the performance and practicability of the guide mechanism.
[0030] Further, as a preferred embodiment of the present application but not limited, the guide plate assembly 34 comprises a sliding seat 341 and a telescopic plate 342 movably connected with the sliding seat 341, the sliding seat 341 is provided with an opening 343 corresponding to the shape of the prism rotating shaft 31, and the prism rotating shaft 31 drives the sliding seat 341 to rotate synchronously.
[0031] In this embodiment, through the cooperation of the sliding seat and the prismatic shaft, and the movable connection of the telescopic plate and the sliding seat, the accurate guidance and flexible adjustment of the material flow direction are realized. The opening on the sliding seat corresponds to the shape of the prismatic shaft, so that the prismatic shaft can pass through the opening and drive the sliding seat to rotate synchronously, thereby adjusting the angle of the guide plate assembly. The movable connection of the telescopic plate and the sliding seat allows the length of the guide plate assembly to be adjusted according to actual needs to adapt to different widths of the vibrating screening machine and different material flow rates. When the flow rate is large, the length of the telescopic plate can be appropriately shortened, and when the flow rate is small, the length of the telescopic plate can be appropriately lengthened. The telescopic plate and the sliding seat can be connected in an interference fit manner. When it is necessary to adjust the angle of the guide plate assembly, the prismatic shaft is rotated, the sliding seat is rotated, and the entire guide plate assembly is driven to change the angle, thereby guiding the material to the target position. When it is necessary to adjust the length of the guide plate assembly, the movable connection of the telescopic plate and the sliding seat changes the extension length of the guide plate assembly to achieve the best material guiding effect.
[0032] Further, as a preferred embodiment of the present scheme but not limited, the flow divider 4 is in a herringbone shape, and the height of the flow divider 4 gradually decreases from the middle to both sides.
[0033] In this embodiment, when the material falls from the discharge port to the flow divider, due to the higher middle and lower sides of the flow divider, the material will naturally be divided to both sides and gradually spread out during the division process. This effectively solves the problem of uneven distribution of material on the vibrating screening machine, ensuring that the material can uniformly cover the entire screening area, thereby improving the utilization rate of the screen hole and the screening efficiency. The flow divider produces a natural division and thinning effect on the material through its herringbone structure and height variation. When the material contacts the flow divider, the material in the middle will flow to both sides due to the height difference and gradually spread out during the flow process, forming a uniform material layer. This process not only avoids material accumulation, but also allows the flow divider to be designed with an adjustable height setting, which can be adjusted according to the characteristics and flow rate of different materials to achieve the best division effect; or an anti-static coating is added to the surface of the flow divider to reduce the formation of clumps of material due to static adsorption during the division process, further improving the screening quality.
[0034] Further, as a preferred embodiment of the present scheme but not limited, the flow divider 4 is provided with an inclined surface 41 on the side facing the discharge port 1, and the inclined surface 41 gradually inclines upward away from the discharge port 1.
[0035] In the embodiment, when the material moves to the flow dividing member, the first contact is the inclined surface. Since the inclined surface gradually inclines upward in the direction away from the discharge port, the material will be subjected to a lateral force at the moment of contacting the inclined surface, which promotes the material to move to the two sides of the flow dividing member and gradually spread. Not only accelerates the material flow process, but also ensures that the material can be more evenly distributed on the entire width of the vibrating screen separator.
[0036] Further, as a preferred embodiment of the present scheme but not limited, the grid member 5 is provided with a plurality of grid openings 51 arranged along the width direction of the vibrating screen separator 2.
[0037] In the embodiment, when the material spreads evenly through the flow dividing member, it will continue to move and encounter the grid member. The plurality of grid openings on the grid member limit the advancing path of the material that does not meet the size requirements. Only the material particles that meet the size requirements can continue to advance through the grid openings, while the material that does not meet the requirements will be limited by the grid openings and cannot pass through. The material that does not meet the size requirements is collected and processed by manual picking, thereby realizing the screening and separation of the material.
[0038] Further, as a preferred embodiment of the present scheme but not limited, the width of the grid opening 51 is L, wherein 10mm≤L≤30mm.
[0039] In the embodiment, when the width of the grid opening is set to 20mm, the tobacco clumps with a diameter greater than 20mm can be effectively screened out; when the width of the grid opening is set to 15mm, the tobacco clumps with a diameter greater than 15mm can be effectively screened out, thereby realizing the accurate screening of the material.
[0040] Further, as a preferred embodiment of the present scheme but not limited, the grid member 5 gradually curves from bottom to top in the conveying direction of the vibrating screen separator 2.
[0041] In the embodiment, when the material layer advances on the vibrating screen separator and contacts the grid member, due to the curved design of the grid member, the material will be subjected to a guiding force when passing through the grid opening, which can produce an additional extrusion effect on the clumpy material, and can extrude the clumpy material to a certain extent to break up part of the clumpy material.
[0042] Further, as a preferred embodiment of the present scheme but not limited, the discharge port 1, the flow dividing member 4, and the grid member 5 are arranged in sequence along the conveying direction of the vibrating screen separator 2.
[0043] Further, as a preferred embodiment of the present application but not limited, the vibrating screening machine 2 comprises an upper layer conveying belt 21, a lower layer conveying belt 22 located below the upper layer conveying belt 21, and a transmission assembly 23 for driving the upper layer conveying belt 21 and the lower layer conveying belt 22 to advance the material along the conveying direction, and a plurality of sieve holes 24 are arranged on the upper layer conveying belt 21.
[0044] In the embodiment, the diameter of the sieve hole is 3mm, and the transmission assembly can adopt two transmission shafts, each of which is equipped with an eccentric block, and the transmission end of the transmission shaft is provided with a synchronous pulley, and the two synchronous pulleys are connected through a synchronous belt. The structure drives the sieve to vibrate for material screening through the exciting force generated by the eccentric block.
[0045] The working principle of the embodiment is as follows:
[0046] The material uniformizing and nodular material removing assembly for the vibrating screening machine of the present application can ensure that the material can be accurately guided to the middle position of the vibrating screening machine by setting a guide mechanism near the discharge port, and then spread evenly along the width direction of the vibrating screening machine by using a flow dividing piece, effectively solving the problem of uneven distribution of tobacco on the vibrating screening machine, and fully playing the screening role of the sieve hole. At the same time, by setting a grid piece on the vibrating screening machine, the nodular material is filtered and limited to move to the next stage along the feeding direction, and the nodular material can be taken out manually, which improves the screening effect of the nodular tobacco, so that the vibrating screening machine can more effectively clean out the fragments and nodular tobacco in the tobacco, and improve the quality and efficiency of the material screening.
[0047] The above is the embodiment provided in combination with specific content, and the specific implementation of the present application is not limited to these descriptions. Any similar structure or technical deduction or replacement made on the basis of the concept of the present application should be considered as the protection scope of the present application.
