Abstract
Description
Technical Field
[0001] The embodiments of the present utility model relate to the technical field of rotor scales, and particularly to an insertion plate structure of a rotor scale and a rotor scale. Background Technique
[0002] The working principle of a rotor scale is as follows: Materials are fed into the feed bin by a metering feeder and enter the annular balance rotor scale from the feed bin. The impeller of the rotor scale rotates, causing the materials to flow evenly from the feed port to the discharge port. Since the scale body adopts a balance structure, at this time, there are materials on one side of the disc-shaped scale body and no materials on the other side, causing the scale body to lose balance. The weight of the materials is detected by a weighing sensor and sent to a control instrument. At the same time, the detected speed signal is also sent to the instrument. After processing, the instantaneous flow rate and cumulative amount are obtained, and the feeding speed can be controlled to adjust the flow rate.
[0003] At present, during the use of rotor scales, it often gets stuck and trips due to material jamming in the sandwich between the inner rotor shell and the outer rotor shell. After inspection, it is found that the reason for the materials to enter the sandwich is as follows: There is a distributor under the feed bin, and a baffle is provided at the position corresponding to the sandwich on the distributor. The baffle is fixed by welding. In this way, a part of the weld of the baffle corresponds to the sandwich position; during use, due to the long-term erosion of the materials, the weld of the baffle will gradually wear, and after a certain degree of wear, holes will be generated, resulting in material leakage into the sandwich.
[0004] In view of this, how to overcome the defects of the existing technology, solve the wear of the weld of the baffle, and solve the problem that the rotor scale gets stuck and trips due to materials entering the sandwich is a difficult problem to be solved in this technical field.

It is only for the convenience of describing the present utility model and does not require the present utility model to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0034] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that those of ordinary skill in the art can make several modifications and improvements without departing from the concept of the present utility model. These all belong to the protection scope of the present utility model.
[0035] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs.

In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0037] During the use of the rotor scale, it often gets stuck and trips due to the material being clamped in the sandwich layer between the inner rotor shell and the outer rotor shell. The reason for the material being clamped in the sandwich layer is that the weld of the baffle plate gradually wears out, and after a certain degree of wear, holes will be generated, resulting in material leakage into the sandwich layer.
[0038] To solve the above problems, the embodiment of the present utility model provides a plug plate structure for a rotor scale and a rotor scale. By arranging a plug plate above the corresponding position of the weld of the baffle plate, during feeding, the material that would originally fall on the baffle plate will fall on the plug plate, so that the plug plate replaces the baffle plate to receive the impact force of the material, thereby avoiding damage to the weld of the baffle plate, solving the problem of wear of the weld of the baffle plate, and preventing the material from entering the sandwich layer and causing the rotor scale to get stuck and trip.
[0039] Specifically, the embodiments of the present utility model will be further described below with reference to the accompanying drawings.
[0040] As Figure 1 shown, the embodiment of the present utility model provides a plug plate structure for a rotor scale, including a bracket 1 and a rotor assembly 2, a feeding assembly 3, and a plug plate assembly 4 arranged on the bracket 1; among them, the rotor assembly 2 is driven by a motor 5 to rotate. For example Figure 1 the motor 5 drives the rotor assembly 2 to rotate through a transmission member 6.
[0041] In some embodiments, the transmission member 6 may include two meshing bevel gears to convert the rotation of the motor 5 in the vertical plane into the rotation of the rotor assembly 2 in the horizontal plane; the transmission member 6 may also include a transmission to adjust the rotation speed of the rotor assembly 2.
[0042] Refer to Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, the rotor assembly 2 includes a rotor inner shell 201 and a rotor outer shell 202, and the gap between the rotor inner shell 201 and the rotor outer shell 202 forms a sandwich layer 203. Specifically, the rotor inner shell 201 can be connected to the central shaft 206 through a support plate 205, and one end of the central shaft 206 is rotatably connected to the rotor outer shell 202, and the other end of the central shaft 206 is connected to the output end of the transmission member 6; thus, when the motor 5 drives the rotor assembly 2 to rotate through the transmission member 6, only the rotor inner shell 201 is driven to rotate by the central shaft 206, while the rotor outer shell 202 remains stationary.
[0043] Refer to Figure 1 、 Figure 2 、 Figure 4As shown, in some embodiments, the feeding assembly 3 includes a feeding bin 301 and a distributor 302. The distributor 302 is arranged below the feeding bin 301, and a part of the baffle 303 of the distributor 302 is located above the interlayer 203. Under this setting, the baffle 303 can block the materials going from the feeding bin 301 to the interlayer 203, so that the materials do not enter the interlayer 203 but all enter the range of the inner rotor shell 201. However, referring to Figure 6 As shown, the baffle 303 is perpendicular to the toroidal surface of the distributor 302, and generally these two are fixed by welding. Under the long-term scouring of the materials, the welding part may be damaged, resulting in leakage of materials into the interlayer 203, causing jamming between the inner rotor shell 201 and the outer rotor shell 202. Based on this situation, referring to Figure 5 As shown, in some embodiments, a through hole 304 is opened at the bottom side wall of the feeding bin 301 corresponding to the baffle 303, and the height of the through hole 304 is higher than the height of the baffle 303; referring to Figure 7 As shown, the plug plate assembly 4 includes a plug plate 401 and a displacement adjustment mechanism, and the displacement adjustment mechanism is used to drive the plug plate 401 to move in the feeding bin 301 along the through hole 304.
[0044] Under the above setting, the plug plate 401 can be inserted into the through hole 304, and then the plug plate 401 is located above the baffle 303. In this way, when the materials fall, they will not impact the baffle 303 but impact the plug plate 401, which can avoid the damage of the weld of the baffle 303 and prevent the situation of material leakage into the interlayer 203. Further, by setting a displacement adjustment mechanism for the plug plate 401, the insertion depth of the plug plate 401 can be controlled. After the front part of the plug plate 401 is severely worn, the plug plate 401 can be adjusted to a deeper position to ensure that the weld of the lower baffle 303 is not worn; through the setting of the displacement adjustment mechanism, the service time of the plug plate 401 can be greatly increased, and the frequent replacement of the plug plate 401 can be avoided.
[0045] Referring to Figure 1 and Figure 7 As shown, in some embodiments, the plug plate assembly 4 further includes a slide rail 402. The slide rail 402 is fixed on the bracket 1 and faces the through hole 304; the plug plate 401 is arranged on the slide rail 402 and is used to move along the slide rail 402. Through the setting of the slide rail 402, the plug plate 401 can be kept moving axially along the direction of the through hole 304.
[0046] Referring to Figure 8As shown, in some embodiments, the slide rail 402 includes a bottom plate 4021, a first side plate 4022, a first top plate 4023, a second side plate 4024, and a second top plate 4025. The bottom plate 4021 is fixed on the bracket 1. The first side plate 4022 is disposed on one side of the bottom plate 4021 and perpendicular to the bottom plate 4021. The first top plate 4023 is disposed on the first side plate 4022 and parallel to the bottom plate 4021. The bottom plate 4021, the first side plate 4022, and the first top plate 4023 form a first limiting space 4026. The second side plate 4024 is disposed on the other side of the bottom plate 4021 and perpendicular to the bottom plate 4021. The second top plate 4025 is disposed on the second side plate 4024 and parallel to the bottom plate 4021. The bottom plate 4021, the second side plate 4024, and the second top plate 4025 form a second limiting space 4027. One side of the insertion plate 401 is located in the first limiting space 4026, and the other side of the insertion plate 401 is located in the second limiting space 4027, so as to limit the insertion plate 401 and enable it to perform axial movement only in the direction towards the through hole 304.
[0047] In some embodiments, the width of the insertion plate 401 is the same as the width of the through hole 304 and is greater than or equal to the maximum width of the baffle plate 303, so as to prevent materials from leaking onto the baffle plate 303.
[0048] Reference Figure 1 and Figure 7 As shown, in some embodiments, the displacement adjustment mechanism includes a screw rod 403, a positioning base 404, and a locking nut 405. The positioning base 404 is fixed on the bracket 1. One end of the screw rod 403 is fixed on the insertion plate 401, and the other end of the screw rod 403 passes through the positioning base 404. There are two locking nuts 405, which are respectively located on the screw rod 403 on both sides of the positioning base 404. Based on the above settings, the movement of the screw rod 403 can be controlled by adjusting the two locking nuts 405, and then the insertion plate 401 can be driven to move to complete the displacement adjustment function.
[0049] In some embodiments, the screw rod 403, the insertion plate 401, and the through hole 304 are located on the same horizontal plane, so that the screw rod 403 can drive the insertion plate 401 to perform axial movement along the through hole 304.
[0050] In some embodiments, the displacement adjustment mechanism can also be an electric telescopic rod or a linear motor or any other device that can drive the insertion plate 401 to perform axial movement.
[0051] Reference Figure 5 and Figure 6As shown, in some embodiments, the distributor 302 is fixedly welded to the inner wall of the bottom of the feed bin 301. A first fixing seat 305 is arranged on the outer side of the bottom of the feed bin 301, and the feed bin 301 is fixed to the bracket 1 through the first fixing seat 305. For example, the first fixing seat 305 and the bracket 1 are fixed by bolts.
[0052] Reference Figure 4 and Figure 9 As shown, in some embodiments, the height of the rotor outer shell 202 is greater than the height of the rotor inner shell 201. A second fixing seat 204 is arranged on the outer side of the top of the rotor outer shell 202, and the rotor outer shell 202 is fixed to the bracket 1 through the second fixing seat 204. For example, the second fixing seat 204 and the bracket 1 are fixed by bolts.
[0053] In some embodiments, the feed bin 301 is made of a composite plate, and a wear-resistant layer is formed inside to ensure its service life. The distributor 302 is made of a wear-resistant weldable steel plate rolled, preventing the distributor 302 from wearing too fast and ensuring uniform feeding of materials.
[0054] The embodiment of the present invention also provides a rotor scale, including the plug plate structure of the above rotor scale. It should be noted that the embodiment of the present invention mainly improves the problem of material leakage from the baffle to the interlayer in the original rotor scale. As for the other original structures of the rotor scale, they are not within the scope of improvement of the present invention, so they are not described in more detail.
[0055] In summary, the embodiment of the present invention provides a plug plate structure of a rotor scale and a rotor scale. By arranging a plug plate above the corresponding position of the weld of the baffle, when feeding, the material that would originally fall on the baffle will fall on the plug plate, so that the plug plate replaces the baffle to receive the impact force of the material, thereby avoiding damage to the weld of the baffle, solving the problem of weld wear of the baffle, and preventing the material from entering the interlayer and causing the rotor scale to get stuck and trip.
[0056] Furthermore, a displacement adjustment mechanism is also provided for the plug plate. The plug plate is driven to move axially through the displacement adjustment mechanism, so that the insertion depth of the plug plate can be controlled. Furthermore, after the front part of the plug plate is severely worn, the plug plate can be adjusted to a deeper position, ensuring that the weld of the lower baffle is not worn; through the setting of the displacement adjustment mechanism, the service time of the plug plate can be greatly improved, avoiding frequent replacement of the plug plate.
