[0014] The electrode paste is screened and polished by rotating a conical sieve body with open ends composed of multiple threaded steel bars. As the sieve body rotates, the electrode paste gradually moves from the feed end to the discharge end of the sieve body. During this process, the distance between two adjacent threaded steel bars gradually increases, which has a screening effect on the scraps of electrode paste of different sizes. The rotating sieve body allows the electrode paste to move toward the discharge end of the sieve body while rotating with the sieve body due to the rotation, and fall during continuous rotation, so that collisions occur between the electrode pastes and between the electrode pastes and the threaded steel bars, thereby enhancing the polishing effect on the electrode paste.

[0032] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0033] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Embodiment 1, as Figure 1-Figure 12 As shown, an electrode paste shaping roller screen according to an embodiment of the present application is rotatably arranged at the discharge end of a conveyor belt, and includes: a screen body 1, a dust removal assembly 2 and a plurality of partitions 3.

[0035] Among them, Figure 1-Figure 3 As shown, the screen body 1 is a conical structure in which a plurality of threaded steel bars are evenly arranged circumferentially and open at both ends, and the centers of the two ends of the screen body 1 are located in the same horizontal plane.

[0036] It should be noted that a waste recovery trough is provided below the screen body 1, and a finished product storage bin (not shown in the figure) is provided at the discharge end thereof.

[0037] In a specific embodiment of the present application, the diameter of the feed end of the sieve body 1 is 1100MM, the diameter of the discharge end of the sieve body 1 is 1300MM, the length of the sieve body 1 is 3000MM, the diameter of the rebar is preferably 20MM, and the rotation speed of the sieve body 1 is 25 revolutions per minute.

[0038] It can be understood that the distance between two adjacent threaded steel bars on the sieve body 1 gradually expands from its feed end to its discharge end. This design will enable the sieve body 1 to have different screening effects on the electrode paste during rotation, and have a better screening effect on the scraps of the electrode paste. As the sieve body 1 rotates, the electrode paste in the sieve body 1 will fall and move toward the discharge end following the rotation. This design will cause the electrode paste to collide with each other and with the threaded steel bars during the displacement from the feed end to the discharge end, thereby having a good polishing effect on the electrode paste, so that the surface of the finished electrode paste discharged from the discharge end of the sieve body 1 is smooth, and the defective rate in the finished product is reduced.

[0039] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Fig. 9 As shown, the dust removal assembly 2 includes a dust removal cover 21 fixedly covered on the upper side of the sieve body 1. The dust removal cover 21 is double-layered, and its inner layer is adapted to the shape of the outer wall of the sieve body 1, and its outer layer is a straight cylinder. It can be seen that the interior of the dust removal cover 21 forms a cavity with a conical inner wall and a cylindrical outer wall.

[0040] Furthermore, a dust removal chamber is arranged between the two layers of the dust removal hood 21, wherein the radial spacing of the dust removal chamber gradually decreases from the feed end to the discharge end of the sieve body 1, and holes for air flow in and out are respectively arranged at both ends of the dust removal chamber, wherein the holes at the air inlet end are larger than the holes at the air outlet end. It can be seen that the air flow enters the dust removal chamber from the air inlet holes and then flows out from the air outlet holes. In this process, the change in the volume of the dust removal chamber will force the flow rate of the air flow to increase.

[0041] Furthermore, a plurality of through grooves are equidistantly arranged on the inner layer of the dust cover 21 along the axial direction of the sieve body 1 , so that the through grooves evenly cover the covered parts of the sieve body 1 .

[0042] It should be noted that the air outlet of the dust removal component 2 is externally connected to an exhaust device. In the specific embodiment of the present application, the exhaust device can adopt a device with an air extraction function in the prior art, and is not specifically limited here.

[0043] like Fig. 9As shown, a plurality of partitions 3 are evenly arranged in the circumferential direction of the dust removal chamber, and the plurality of partitions 3 are respectively spaced apart from the holes for air inlet and outlet at both ends of the dust removal chamber. Thus, the partitions 3 divide the dust removal chamber into a plurality of independent channels.

[0044] In addition, an electrode paste shaping roller screen according to an embodiment of the present application also has the following additional technical features:

[0045] like Figure 1-Figure 3 As shown, two ends of the screen body 1 are coaxially connected with a follower 12, a bracket 11 is arranged on the bottom side of the screen body 1, and at least four positioning wheels 13 are arranged on the bracket 11. The positioning wheels 13 are respectively located on both sides of the follower 12, and the positioning wheels 13 and the follower 12 are abutted. Further, the follower 12 includes a feed end driven ring 121 arranged at the feed end of the screen body 1 and a discharge end driven ring 122 arranged at the discharge end of the screen body 1. A motor 131 is mounted on the bracket 11, and the motor 131 and one of the positioning wheels 13 are connected by a shaft key. Therefore, it can be understood that the motor 131 can drive the screen body 1 to rotate on the bracket 11 through the positioning wheel 13.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, both ends of the dust cover 21 are arranged in a semicircular ring shape, and the two bottom ends of the dust cover 21 are symmetrically fixed with arc support plates 211. The shape of the inner wall of the arc support plate 211 is adapted to the shape of the side wall of the sieve body 1, and the arc support plate 211 is mounted on the bracket 11.

[0047] It should be noted that during the rotation of the sieve body 1, the electrode paste inside it will rotate with the rotation of the sieve body 1, but under the action of its own gravity, the electrode paste will fall after rotating to a certain position. In this way, the electrode paste will continue to rotate, roll and axially displace in the sieve body 1. It can be understood that the semicircular ring setting of the dust hood 21 is sufficient to cover the upper half of the sieve body 1. During the normal use of the sieve body 1, no matter how much electrode paste is transported into it, the dust generated during the movement is sufficient to be covered by the dust hood 21 (not to mention the dust leaked at both ends of the sieve body 1). The setting of the arc support plate 211 can guide the scraps falling from the sieve body 1, so that the scraps falling on the arc support plate 211 fall into the recovery trough below the sieve body 1.

[0048] like Figure 4 and Figure 5As shown, the end of the dust hood 21 facing the feed end of the sieve body 1 is an air inlet end plate 22, and the end of the dust hood 21 facing the discharge end of the sieve body 1 is an air outlet end plate 23; a plurality of air inlet holes 221 are equidistantly arranged on the air inlet end plate 22; a plurality of air outlet holes 231 are equidistantly arranged on the air outlet end plate 23; the number of the air inlet holes 221 is the same as the number of the air outlet holes 231, and the diameter of the air inlet holes 221 is larger than the diameter of the air outlet holes 231. Furthermore, the dust removal chamber is a special-shaped chamber 24, and the plurality of through grooves arranged on the inner layer of the dust hood 21 are spiral through grooves 241, and the spiral through grooves 241 are connected to the special-shaped chamber 24. It can be seen that the airflow enters the special-shaped cavity 24 from the air inlet 221 and finally flows out from the air outlet 231. In this process, the airflow will be accelerated by the change in the flow volume, and suction will be formed in the direction of the spiral groove 241 (Venturi effect), and as the airflow gradually approaches the direction of the air outlet 231, its flow rate gradually increases, and then the suction at the spiral groove 241 gradually increases from the direction of the air inlet 221 to the direction of the air outlet 231. This design, combined with the actual use process, the dust at the feed end of the sieve body 1 will be significantly less than the dust in the direction of the discharge end, and a better adsorption effect is formed on the dust inside the entire sieve body 1. The design of the spiral groove 241 also allows the dust removal hood 21 to form a relatively uniform suction on the inside of the sieve body 1, thereby avoiding the escape of dust at both ends of the sieve body 1 to a certain extent.

[0049] like Figure 4 , Figure 6 and Figure 7 As shown, a flow equalizing chamber 25 is fixedly connected to one side of the air outlet end plate 23 away from the air inlet end plate 22. The flow equalizing chamber 25 is arranged in a semicircular ring shape, and both ends of the flow equalizing chamber 25 are respectively connected to an external exhaust device to form an airflow inside the dust cover 21.

[0050] Furthermore, an arc-shaped cavity is provided inside the flow-equalizing chamber 25, and a sealing plate 251 is provided inside the arc-shaped cavity along the radial direction; the arc-shaped cavity is connected to the air outlet 231, and the arc-shaped cavity is evenly divided into two chambers by the sealing plate 251 from the middle; the sealing plate 251 symmetrically divides the multiple air outlets 231 into two groups. It can be seen from this that the external exhaust devices on both sides will generate suction to the inside of the two chambers respectively, and the two groups of air outlets 231 will transfer the suction to the inside of the dust cover 21 respectively. It can be understood that when the suction provided by the two external exhaust devices is the same, the uniform setting of the air outlets 231 will make the suction at the multiple air outlets 231 corresponding to the arc-shaped cavity inside the flow-equalizing chamber 25 roughly the same, and then a more balanced airflow will be formed in the special-shaped cavity 24.

[0051] Furthermore, the two bottom ends of the flow equalizing chamber 25 are respectively connected to air duct connectors 252, which are connected to an external exhaust device so that the exhaust device can provide suction to the interior of the flow equalizing chamber 25 while taking away the adsorbed dust, thereby reducing the possibility of dust accumulation inside the flow equalizing chamber 25.

[0052] like Figure 2 , Figure 9-11 As shown, a plurality of special-shaped blocks 31 are evenly arranged on one side of the partition 3 facing the screen body 1, and the special-shaped blocks 31 are sealed and inserted in the spiral groove 241. In this way, it can be understood that the partition 3 and the special-shaped blocks 31 thereon evenly divide the special-shaped cavity 24 into a plurality of independent gradient air passages along the axial direction, and the two ends of each gradient air passage correspond to an air inlet hole 221 and an air outlet hole 231 respectively. Furthermore, through the setting of the gradient air passage, the airflow in the entire special-shaped cavity 24 will be made more balanced.

[0053] Furthermore, the partition 3 itself is also arranged in a gradient shape, and its height on the side facing the feed end of the sieve body 1 is greater than its height on the side facing the discharge end of the sieve body 1, and its thickness on the side facing the feed end of the sieve body 1 is less than its thickness on the side facing the discharge end of the sieve body 1. It can be understood that at this time, the four side walls of the independent gradient airway will form a three-side convergent shape, so when the airflow flows in the independent airway, its acceleration will be more obvious.

[0054] The following describes the use process of an electrode paste shaping roller screen according to an embodiment of the present application with reference to the accompanying drawings:

[0055] When in use, the formed electrode paste is continuously conveyed to the feed end of the rotating screen body 1 by the conveyor belt. Under the rotation of the screen body 1, the electrode paste will follow the rotation, fall and move toward the discharge end. The design of the distance between two adjacent threaded steel bars on the screen body 1 gradually expanding from the feed end to the discharge end will enable the screen body 1 to have different screening effects on the electrode paste during the rotation process, and have a better screening effect on the scraps of the electrode paste. At the same time, the electrode pastes will collide with each other and with the threaded steel bars during the displacement process from the feed end to the discharge end, thereby causing the electrode paste to collide with each other. The electrode paste discharged from the discharge end of the sieve body 1 has a good grinding effect, so that the surface of the finished electrode paste is smooth, and the defective rate of the finished product is reduced. In the process of screening and grinding the electrode paste, the electrode paste will cause dust to be generated in the sieve body 1 due to collision. In this process, starting the external exhaust device will generate suction inside the two chambers in the flow equalization cabin 25, and the suction is transmitted to the inside of the dust removal cover 21 by the two groups of air outlets 231, and finally transmitted to the direction of the air inlet 221, so that airflow is formed inside the special-shaped cavity 24, and a plurality of gradient partitions 3 are arranged inside the dust removal cover 21, and a three-side contraction is formed between two adjacent partitions 3. The gradual air passage has a shaped shape, so the airflow formed by the suction force will be uniform in the flow rate of each group of gradual air passages, and the flow rate of the airflow from the air inlet end to the air outlet end will be gradually accelerated due to the volume change of the gradual air passage. Therefore, the airflow will form suction (Venturi effect) on the spiral grooves 241 through which it passes. The spiral grooves 241 are evenly arranged on the inner side of the dust removal cover 21, and the two adjacent partitions 3 divide the multiple spiral grooves 241, so that each independent gradual air passage has multiple divided spiral grooves 241 evenly distributed along the axial direction. Therefore, the entire sieve body 1 will be covered by the dust removal cover 21. Suction, and the size of the suction force changes gradually from the feed end to the discharge end of the screen body 1, and in actual use, the dust formed inside the screen body 1 from the feed end to the discharge end also gradually increases. Therefore, this design will make the screen body 1 in the process of screening, grinding and conveying the electrode paste. Most of the dust formed will be sucked into the dust removal hood 21, and finally follow the flow of air to be conveyed to the external exhaust device for subsequent dust reduction treatment, which greatly alleviates the phenomenon of dust escaping from both ends of the screen body 1, eliminates the possibility of dust escaping from the upper side of the screen body 1, and reduces the dust imagination during the screen body 1 to shape the electrode paste.

[0056] Embodiment 2. In the related art, although the flow equalizing chamber 25 and the air outlet holes 231 are connected to each other and the air outlet holes 231 are evenly distributed on the air outlet end plate 23, the position of the airway joint 252 will eventually cause a difference in the suction force at each air outlet hole 231, which will then cause a certain difference in the flow rate of the airflow in the gradient airway corresponding to the air outlet hole 231. Once the number of gradient airways is relatively small, it will affect the suction force generated by the spiral grooves 241 in the local gradient airway on the screen body 1, thereby affecting the local treatment effect of dust inside the screen body 1.

[0057] According to some embodiments of the present application, Figure 2 , Figure 6-Figure 8 As shown, a fine-tuning component 4 is provided in the flow equalizing chamber 25, and the fine-tuning component 4 includes: a plurality of diverter plates 41, a plurality of fine-tuning plates 42 and a plurality of guide rods 43. The plurality of diverter plates 41 are fixed to the air outlet end plate 23 at equal distances, and are spaced apart from the air outlet hole 231. The plurality of fine-tuning plates 42 elastically slide between two adjacent diverter plates 41. The plurality of guide rods 43 are arranged in groups of two, and each group of guide rods 43 is respectively fixed to the two sides of the air outlet hole 231, and slides with the fine-tuning plates 42.

[0058] The top and bottom sides of the splitter plate 41 are respectively fixed to the top and bottom sides of the flow equalizing chamber 25, and the end thereof away from the outlet end plate 23 does not abut against the inner wall of the flow equalizing chamber 25 (such as Figure 6 as shown).

[0059] As a result, an independent chamber of the same size will be formed locally at each air outlet 231 , and each independent chamber is connected to the flow equalizing chamber 25 , that is, multiple independent chambers are connected in parallel in the flow equalizing chamber 25 .

[0060] Specifically, the fine-tuning plate 42 is provided with a through hole 421 matched with the air outlet 231 to facilitate the passage of airflow.

[0061] Furthermore, a spring 431 is provided on the upper limit sleeve of the guide rod 43 , and the other end of the spring 431 abuts against the fine-tuning plate 42 . It should be noted that a baffle for limiting is provided at one end of the guide rod 43 away from the air outlet end plate 23 , and abuts against the spring 431 .

[0062] It should be noted that the multiple springs 431 have the same parameters such as structure, size, elastic force, etc.

[0063] Therefore, in actual use, when the exhaust device provides suction, the suction is transmitted to each independent chamber in "parallel" through the flow equalizing chamber 25, and the suction is transmitted to the air outlet 231 through the through hole 421 on the fine-tuning plate 42 in each independent chamber. In this process, due to the "parallel" effect formed between multiple independent chambers, the suction size inside them can be kept consistent, and when the suction is greater than the elastic force of the spring 431, the fine-tuning plate 42 will be forced to move away from the air outlet 231 along the guide rod 43, squeezing the spring 431, and the spring 421 in each chamber will be squeezed. The setting of 31 will achieve fine-tuning of the suction force in each chamber, that is, for the chamber with large suction, the fine-tuning plate 42 therein will form a larger stroke extrusion on the corresponding spring 431, and for the chamber with small suction, the fine-tuning plate 42 therein will form a smaller stroke extrusion on the corresponding spring 431. In this way, the suction at each air outlet 231 can be further balanced by utilizing the deformation of the fine-tuning plate 42 and the corresponding spring 431, so that the flow rate of the airflow in each independent gradient airway is balanced, and then the dust removal effect of the entire dust removal hood 21 on the inside of the sieve body 1 is balanced.

[0064] Embodiment three, in the related art, the air inlet 221 of the dust cover 21 of the electrode paste shaping roller screen will enter the external airflow. Once there are floating cotton-like debris in the use environment, they will be sucked into the special-shaped cavity 24 due to the action of the airflow. As the volume of the corresponding gradient airway gradually decreases, the gradient airway may be partially blocked, and finally the dust treatment effect on the screen body 1 will be affected.

[0065] According to some embodiments of the present application, Figure 1 , Figure 2 and Fig.12 As shown, a plurality of blocking members 5 are equidistantly arranged on the air inlet end plate 22, and the plurality of blocking members 5 correspond to the air inlet holes 221 one by one, respectively. The blocking members 5 can rotate under the action of the airflow.

[0066] The blocking member 5 includes: a rotating blade 51 and a positioning frame 52 . The rotating blade 51 is rotatably disposed in the air inlet 221 ; the positioning frame 52 is coaxially fixed to the outer side of the air inlet 221 ; and the rotating blade 51 is coaxially rotatably connected to the positioning frame 52 .

[0067] It should be noted that the positioning frame 52 is provided with support rods, so that an airflow channel is formed on the positioning frame 52 and a certain interception effect is achieved by utilizing the support rods.

[0068] Therefore, during specific use, since airflow from the outside will flow into the interior of the special-shaped cavity 24 through the air inlet 221, the rotating blade 51 installed in the air inlet 221 will be forced to rotate under the action of the airflow, and a positioning frame 52 with a support rod is also provided on the outside of the air inlet 221, so the floating matter carried in the airflow will first be intercepted by the support rod, and secondly, the rotating rotating blade 51 will also have a certain interception effect on the solid debris coming with the airflow (when the solid debris passes through the rotating blade 51, some of it will be hit and ejected out of the air inlet 221), and the rotating fixed rotating blade 51 will also have a certain cutting effect on the floating matter, reducing the possibility of clogging the gradient airway after it enters. At the same time, it should be noted that the design of the rotating blade 51 makes the airflow after entering the air inlet 221, in each corresponding gradient airway, become uniform due to the rotation of the fluid, that is, to a certain extent, reduce the airflow imbalance phenomenon that may exist in each independent gradient airway, and further enhance the dust removal effect of the entire dust removal hood 21 on the inside of the sieve body 1.

[0069] It should be noted that the specific models and specifications of the positioning wheel 13, the feed end driven ring 121, the discharge end driven ring 122, the motor 131, the airway connector 252, the spring 431 and the rotating blade 51 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in the field, so it will not be described in detail.

[0070] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
