Description

Technical Field

[0001] This utility model relates to the field of vibrating screening technology, specifically a vibrating screen for the production of porcelain insulators. Background Technology

[0002] In the production of porcelain insulators, raw material selection is a crucial step in ensuring product quality. Porcelain insulators are typically made from ceramic raw materials such as kaolin, feldspar, and quartz through processes including mixing, molding, and sintering. The particle size and uniformity of the raw materials directly affect the stability of the molding process and key indicators of the final product, such as mechanical strength and insulation performance. Therefore, fine screening of the raw materials is necessary before production to ensure that the particle distribution meets the process requirements.

[0003] Traditional vibrating screens are widely used in the production of porcelain insulators. They use a motor-driven vibrator to generate excitation force, causing the material on the screen to undergo a throwing motion, thus achieving particle classification of different sizes. However, existing vibrating screens still have the following problems in the screening process of porcelain insulator raw materials: When it is necessary to screen materials for porcelain insulators of different sizes, it is usually necessary to replace the screen. However, the screen is usually large in size, and its disassembly and transportation are easily restricted when encountering a small working space.

[0004] Therefore, there is an urgent need for a foldable screen structure that allows the screen to be folded and retracted, significantly reducing the space occupied and facilitating disassembly, transportation, and replacement in confined working environments. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a vibrating screen for the production of porcelain insulators. The screen mesh achieves its telescopic effect through a multi-segment telescopic frame structure, making it more convenient to replace the screen mesh and telescopic frame when needed. This greatly reduces the operating space required for disassembly and makes it more suitable for narrow or densely packed work environments, thus lowering the requirements for the work site.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vibrating screen for the production of porcelain insulators, comprising a mounting frame, a material collection frame, a feed inlet, and a vibrating motor: The material hopper is provided with a front frame and a rear frame at both ends along the material flow direction. The front frame and the rear frame are connected by a telescopic component at both ends. The three together form a frame structure. A screen is provided inside the frame structure. The telescopic component is composed of multiple connecting plates of varying sizes that slide and connect with each other. The front frame, the rear frame, the telescopic component, and the screen constitute a telescopic screening component. The front frame is provided with multiple locking posts, and the inner wall of the material collection frame is provided with round holes that are adapted to the locking posts. The locking posts are inserted into the round holes for fixation when the telescopic screening assembly is installed. The screen is an elastic mesh.

[0007] In some embodiments, a fixing frame is slidably provided on the inner wall of the material collection frame, and a plurality of locking blocks are provided on the fixing frame. Each connecting plate has locking holes at both the front and rear ends that are adapted to the locking blocks, and each locking block is inserted into the locking holes to fix each connecting plate.

[0008] In some embodiments, the front frame is provided with a sleeve rod, the material catcher is provided with a mounting block at one end of the rear frame, the mounting block is provided with a guide wheel for guiding the pull rope, and one end of the pull rope is sleeved on the sleeve rod.

[0009] In some embodiments, the pull rope has a handle at one end of the guide wheel, and the guide wheel has a limiting block through which the pull rope passes.

[0010] In some embodiments, the front frame is provided with a plug-in block, the rear frame is provided with a fixing block, and the fixing block has an opening adapted to the plug-in block.

[0011] In some embodiments, the end of the plug block is constricted.

[0012] In some embodiments, the insertion end of the card block has beveled edges on all four sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The screen of this utility model can achieve the effect of screen extension and retraction through a multi-segment telescopic frame structure, making it more convenient to replace the screen and telescopic frame when needed. It greatly reduces the operating space required for disassembly and retraction, making it more suitable for narrow or densely packed working environments and reducing the requirements for the work site.

[0014] The insertion and engagement of the card block and card hole in this invention prevents the frame structure already installed in the material collection frame from loosening due to vibration during operation, thereby enhancing the stability of the equipment and extending its service life.

[0015] The combination of the locking post and the round hole in this invention allows the screen and frame structure to be fixed more quickly in the material collection frame, achieving a rapid separation effect. This reduces the time-consuming operations of repeatedly tightening and loosening bolts and prying the buckles required in traditional disassembly, significantly improving efficiency.

[0016] This invention allows the front frame to move towards the discharge end of the material-collecting frame by pulling a rope, eliminating the need for workers to move the front frame to the discharge end of the material-collecting frame. This reduces the workload of workers and makes retracting the frame structure easier and more convenient. Furthermore, the guide wheel design makes pulling the rope smoother and more convenient.

[0023] Please see Figure 1-8 This embodiment provides a vibrating screen for the production of porcelain insulators, including a mounting frame 1, a material collection frame 2, a feed inlet 3, and a vibrating motor 31. A material collection frame 2 is fixedly connected to the mounting frame 1. One end of the material collection frame 2 is closed, and the other end is an opening for discharging material. The inlet 3 is fixed to the closed end of the material collection frame 2 by welding. like Figure 1 , 2 As shown, during operation, the worker pours the porcelain insulator raw material from the feed inlet 3 into the material collection frame 2, and then starts the vibration motor 31. The discharge end of the material collection frame 2 is lower than the feed end, which causes the porcelain insulator raw material to move towards the discharge end when the vibration motor 31 vibrates due to the lower discharge end.

[0024] The material collection frame 2 has a front frame 41 and a rear frame 42 at both ends along the material flow direction. Both the front frame 41 and the rear frame 42 are made of iron and are U-shaped. Their outer walls fit snugly against the inner wall of the material collection frame 2. Telescopic components connect the two ends of the front frame 41 and the rear frame 42, and the three together form a frame structure. This frame structure is adapted to the inner wall of the material collection frame 2. A screen 5 is installed inside the frame structure. The screen 5 is made of high-elasticity spring steel, which has strong fatigue resistance and high elasticity. The screen 5 is welded... The telescopic assembly is constructed by welding both ends to the inner walls of the front frame 41 and the rear frame 42. It consists of multiple connecting plates 4 of varying sizes that slide together. Each connecting plate 4 adopts a U-shaped structure design, with guide rails on its inner wall and corresponding protrusions on its outer wall. The connecting plate 4 closest to the rear frame 42 has the largest radial width, and the radial width of the subsequent connecting plates 4 decreases sequentially. The subsequent connecting plate 4 forms a sliding fit with the guide rail on the inner wall of the previous connecting plate 4 through the protrusions on its outer wall, thus achieving a hierarchical nested back-and-forth sliding connection. The front frame 41, the rear frame 42, the telescopic assembly, and the screen 5 constitute the telescopic screening assembly. like Figure 2 As shown, the screen 5 is set in the middle of the material collection frame 2. When screening the porcelain insulator raw materials, the finer porcelain insulator raw materials will fall to the bottom of the material collection frame 2, while the larger porcelain insulator raw materials will remain on the screen 5 to achieve the screening effect. As the vibrating motor 31 operates, both the porcelain insulator material that falls to the bottom of the material collection frame 2 and the porcelain insulator material that remains on the screen 5 will be discharged from the discharge end of the material collection frame 2.

[0025] The front frame 41 is provided with multiple locking posts 7. The surface of the locking posts 7 is engraved with cross knurling and is made of iron. The inner wall of the material collection frame 2 is provided with round holes 8 that are adapted to the locking posts 7. The locking posts 7 are inserted into the round holes 8 for fixation when the telescopic screening component is installed. like Figure 2 , 3 As shown in Figure 4, when it is necessary to disassemble the telescopic screening component, the worker first walks to the front frame 41, holds the frame of the front frame 41 with his hand, and then pulls it outward with force to disengage the locking post 7 from the round hole 8. Then, holding the front frame 41, he moves it towards the rear frame 42. During the movement, the telescopic component will slowly fold up. After the front frame 41 moves to the point where the telescopic component is completely folded up, the entire telescopic screening component can be directly detached from the material collection frame 2. After detachment, since it occupies less space after folding, it has stronger applicability in operation scenarios with narrow working space or dense equipment layout, which can effectively reduce the requirements for the working site conditions.

[0026] In some embodiments, a fixing frame 6 is provided on the inner wall of the material collection frame 2, which slides up and down. The length of the fixing frame 6 is the same as that of the telescopic component when it is not folded. Its shape is a long strip. The fixing frame 6 is provided with a plurality of locking blocks 601. The locking blocks 601 form a 90-degree perpendicular angle with the direction of the fixing frame 6 and are rectangular. Each connecting plate 4 has locking holes 61 at both the front and rear ends that are adapted to the locking blocks 601. Each locking block 601 is inserted into the locking holes 61 to fix each connecting plate 4.

[0027] like Figure 5 As shown, in actual operation, in order to prevent the locking post 7 from dislodging from the round hole 8 due to prolonged vibration during operation, when the telescopic screening component is in an unfolded and undisassembled state, the operator holds the fixing frame 6 and slides it downward to insert multiple locking blocks 601 into the locking hole 61, so that the telescopic screening component remains in an unextended state. Under vibration conditions, the locking post 7 has no room for movement, which ensures that it will not fall out of the round hole 8.

[0028] In some embodiments, the front frame 41 is provided with a sleeve rod 12, which is made of iron. The upward-facing end of the sleeve rod 12 is spherical and slightly larger. When the rope is looped around the cylinder, the spherical shape acts as a stop at the end, preventing the rope 9 from slipping out of the cylinder and thus providing a fixing function. The material collection frame 2 is provided with a mounting block 10 at one end of the rear frame 42. The mounting block 10 is provided with a guide wheel 11 for guiding the rope 9. The mounting block 10 is fixedly connected to the guide wheel 11 by welding. One end of the rope 9 is looped around the sleeve rod 12.

[0029] like Figure 6 , 7 As shown, in actual work, the staff first lifts the fixing frame 6 upwards to disengage the locking block 601 from the locking hole 61. After disengagement, the staff grabs the end of the pull rope 9 near the rear frame 42 and pulls it towards the rear frame 42. When the front frame 41 is pulled until it can no longer be pulled, the entire telescopic screening component has been folded and can be directly disassembled. There is no need for the staff to move to the position of the front frame 41 and then to the position of the rear frame 42 to disassemble and fold, making the folding more convenient and faster.

[0030] In some embodiments, the pull rope 9 has a handle 13 at one end of the guide wheel 11. The handle 13 is made of wood and has a pattern engraved on its surface to increase friction. The guide wheel 11 has a limiting block 14 through which the pull rope 9 passes. The limiting block 14 has a hole slightly larger than the pull rope 9 to facilitate the sliding of the pull rope 9 in the hole.

[0031] like Figure 7 As shown, in order to prevent the rope 9 from falling to the ground and to make it easier to hold, a limit block 14 and a handle 13 are provided. The handle 13 has a slightly larger hole than the limit block 14. In actual work, after using the pull rope 9, since the pull rope 9 has no restrictions, it is easy to fall to the ground or other places after use. This makes it necessary to find the pull rope 9 when using it again. Therefore, the limit block 14 restricts one end of the pull rope 9 to prevent it from falling to the ground or other places, so that it is not necessary to search for it when working again.

[0032] In some embodiments, the front frame 41 is provided with a plug-in block 15, and the rear frame 42 is provided with a fixing block 16. The fixing block is fixed to one end of the rear frame 42 by welding, and the fixing block 16 has an opening that matches the plug-in block 15.

[0033] like Figure 8 As shown, during the folding process of the telescopic screening assembly, the insertion block 15 moves synchronously with the frame 41. As the folding action progresses, the insertion block 15 gradually inserts into the opening of the fixing block 16. Although the outer wall size of the insertion block 15 is slightly smaller than the inner wall size at the opening of the fixing block 16 (there is a small gap), a stable connection effect can still be achieved.

[0034] In some embodiments, the end of the plug block 15 is constricted.

[0035] like Figure 8 As shown, the constricted shape of the plug-in block 15 is to allow for better insertion into the opening of the fixing block 16.

[0036] In some embodiments, the four sides of the insertion end of the card block 601 are chamfered.

[0037] like Figure 5 As shown, the chamfering on all four sides of the card block 601 allows for faster insertion into the card slot.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
