Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and more specifically, to a high-frequency screen automatic rolling shutter device. Background Technology

[0002] The automatic roller shutter device for high-frequency screens is an innovative protective device designed to address the problem of slurry splashing during high-frequency screen operations. Its core function is to achieve intelligent closure and opening of the screen perimeter through a dynamic roller shutter structure. Currently, when processing large volumes of ore, slurry splashing in high-frequency screens has become a key bottleneck restricting production efficiency and equipment stability. Splashed slurry not only directly corrodes the screen structure, shortening equipment lifespan, but also prevents a large amount of valuable ore from entering subsequent processes, resulting in resource waste and increased production costs. Current mainstream solutions have significant limitations: while reducing the feed rate to control splashing can alleviate the problem, it significantly weakens the equipment's processing capacity, directly impacting the company's production targets; while using welded baffles to block splashing alters the dynamic balance of the screen body, leading to abnormal high-frequency vibration energy distribution, causing decreased screening efficiency and the risk of equipment fatigue damage. Neither solution achieves a balance between production efficiency and equipment protection. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic rolling shutter device for high frequency screens, which has the advantage of easily preventing the corrosive effect of ore splashing on the screen body.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic high-frequency screen rolling shutter device, comprising a high-frequency screen body, a limiting post fixedly installed on the outer side of the high-frequency screen body, a transmission rod movably installed on the outer surface of each limiting post, a fixing frame fixedly installed on the back of each transmission rod, and a limiting strip movably installed inside the fixing frame and the transmission rod.

[0005] The outer side of the high-frequency screen body is fixedly equipped with a fixed bracket, the top of the inside of the fixed bracket is fixedly equipped with a support base, the inside of the support base is movably equipped with a motor, and the output end of the motor is fixedly equipped with a welded pipe; and one end of the welded pipe passes through the inside of the fixed bracket.

[0006] A curtain is fixedly installed on the outer surface of the welded pipe, and one end of the curtain is fixedly connected to the outer surface of the limiting strip.

[0007] As a preferred embodiment of this utility model, a box body is fixedly installed on the left side of the fixed frame, a positioning block is movably installed inside the limiting strip, a pull rod is fixedly installed at one end of the positioning block, and one end of the pull rod passes through the box body, and a spring is fixedly installed between the positioning block and the box body.

[0008] As a preferred embodiment of this utility model, a support plate is fixedly installed at the bottom of the high-frequency screen body, and a fixing plate is fixedly installed between the two support plates.

[0009] As a preferred embodiment of this utility model, a fixing block is fixedly installed on the outer side of the support plate, a movable block is movably installed inside the fixing block, and a toolbox is fixedly installed on the front of the movable block.

[0010] As a preferred embodiment of this utility model, the inner diameter of the fixed block is equal to the outer diameter of the moving block, and the interior of the fixed block has a smooth surface design.

[0011] As a preferred embodiment of this utility model, a reinforcing rib is fixedly installed at the angle between the support plate and the fixing plate, and the reinforcing rib is triangular in shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Compared with traditional devices, this utility model uses a motor to open and cover the curtain on top of the high-frequency screen body by rotating the motor in both directions, effectively preventing slurry splashing and completely eliminating the risk of corrosion of the screen body's metal structure; the welded pipe drive replaces manual operation, achieving precise opening and closing control of the curtain, ensuring the rated ore processing capacity while reducing the frequency of manual intervention; the matching quick-release curtain structure shortens the material cleaning time, and with the automatic winding function, a single person can complete the daily maintenance work.

[0014] 2. Compared with traditional devices, this utility model uses the cooperation between positioning blocks, springs and housings to install the curtain on the outer surface of the transmission rod.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an automatic high-frequency screen rolling shutter device, including a high-frequency screen body 1. Limiting posts 4 are fixedly installed on the outer side of the high-frequency screen body 1. Transmission rods 3 are movably installed on the outer surface of the limiting posts 4. A fixing frame 7 is fixedly installed on the back of the transmission rods 3. Limiting strips 8 are movably installed inside the fixing frame 7 and the transmission rods 3. Fixing brackets 20 are fixedly installed on the outer side of the high-frequency screen body 1. A support base 19 is fixedly installed on the top of the inside of the fixing bracket 20. A motor 6 is movably installed inside the support base 19. A welded pipe 5 is fixedly installed at the output end of the motor 6, and one end of the welded pipe 5 passes through the inside of the fixing bracket 20. A curtain 2 is fixedly installed on the outer surface of the welded pipe 5, and one end of the curtain 2 is fixedly connected to the outer surface of the limiting strip 8.

[0023] After the staff has fixed the curtain 2 between the transmission rod 3 and the welded pipe 5, when it is necessary to lift the curtain 2, the motor 6 is turned on at the bottom of the support base 19 to rotate forward. The motor 6 drives the welded pipe 5 to rotate inside the fixed bracket 20. Now the welded pipe 5 rolls up the curtain 2, and the curtain 2 drives the transmission rod 3 to rotate on the outer surface of the limiting post 4 until the curtain 2 fully unfolds the high-frequency screen body 1. The motor 6 then stops rotating. When it is necessary to cover, the motor 6 is turned on to rotate in reverse. The motor 6 drives the welded pipe 5 to rotate. At this time, the curtain 2 is pushed by the welded pipe 5 to rotate on the outer surface of the limiting post 4 until the top of the high-frequency screen body 1 is completely covered. The motor 6 then stops rotating, thus completing the lifting and covering of the curtain 2.

[0024] Once the curtain 2 is fixed between the transmission rod 3 and the welded pipe 5, its opening and covering actions are driven by the motor 6. The unfolding process: When the motor 6 starts rotating forward, the welded pipe 5 rotates within the fixed bracket 20 and rolls up the curtain 2. Simultaneously, the curtain pulls the transmission rod 3 to roll out along the outer surface of the limiting post 4. When the curtain is fully unfolded and covers the high-frequency screen body 1, the motor automatically stops. The covering process: When the motor 6 reverses, it drives the welded pipe 5 to rotate in the opposite direction to release the curtain 2. The welded pipe pushes the transmission rod 3 to roll in the opposite direction along the limiting post 4 until the curtain completely covers the high-frequency screen. The screen body 1 and motor 6 stop again. Compared with traditional devices, this device uses the forward and reverse rotation of motor 6 to open and close the top curtain 2 of the high-frequency screen body 1, effectively preventing slurry splashing and completely eliminating the risk of corrosion of the screen body's metal structure. The welded pipe 5 drives the curtain 2 to open and close precisely, ensuring the rated ore processing capacity while reducing the frequency of manual intervention. The matching quick-release curtain structure shortens the material cleaning time, and with the automatic winding function, a single person can complete the daily maintenance work.

[0025] The fixed frame 7 has a box 12 fixedly installed on its left side, the limiting strip 8 has a positioning block 10 movably installed inside, one end of the positioning block 10 has a pull rod 11 fixedly installed, and one end of the pull rod 11 passes through the box 12. A spring 9 is fixedly installed between the positioning block 10 and the box 12.

[0026] Before using the curtain 2, the staff needs to install the curtain 2 on the outer surface of the welded pipe 5 and the limiting strip 8. By holding the pull rod 11, the staff pulls the positioning block 10 inside the transmission rod 3 towards the housing 12. The positioning block 10 compresses the spring 9 inside the housing 12, causing the positioning block 10 to pass through the transmission rod 3 and enter the housing 12. At this time, one end of the curtain 2 is installed on the top of the limiting strip 8. Then, the staff holds the limiting strip 8 and slowly inserts it into the transmission rod 3 and the fixing frame 7. When the limiting strip 8 is fully inserted into the transmission rod 3, the staff releases the pull rod 11. The spring 9 compresses the positioning block 10 inside the housing 12, causing the positioning block 10 to pass through the limiting strip 8. The positioning block 10 limits the limiting strip 8 inside the transmission rod 3 and the fixing frame 7. Then, the staff fixes the other end of the curtain 2 on the outer surface of the welded pipe 5, thus completing the installation of the curtain 2.

[0027] Before installing the curtain 2, one end of the curtain 2 needs to be fixed to the outer surface of the welded pipe 5, and the other end needs to be installed on the top of the limiting strip 8. First, by holding the pull rod 11, pull the positioning block 10 to move towards the housing 12 inside the transmission rod 3, while simultaneously squeezing the spring 9, so that the positioning block 10 passes through the transmission rod 3 and enters the housing 12. Then, install one end of the curtain 2 on the top of the limiting strip 8, and slowly insert the limiting strip 8 into the transmission rod 3 and the fixing frame 7. When the limiting strip 8 is completely inside the transmission rod 3, release the pull rod 11, and squeeze the positioning block 10 again using the spring 9, so that the positioning block 10 passes through the interior of the limiting strip 8 and exits from the housing 12. The limiting strip 8 is positioned inside the transmission rod 3 and the fixing frame 7. Finally, the other end of the curtain 2 is fixed to the outer surface of the welded pipe 5 to complete the installation process. Compared with traditional devices, this device uses the cooperation between the positioning block 10, the spring 9 and the housing 12 to install the curtain 2 on the outer surface of the transmission rod 3. The simple installation method significantly shortens the installation and debugging time of the equipment. Operators can quickly complete the installation of the curtain 2 without complicated tools or professional skills, which helps to improve production efficiency and reduce equipment downtime. In this way, when rolling up, the curtain 2 can also be tightly wrapped around the transmission rod without taking up too much space, which is conducive to the compact design of the equipment.

[0028] The bottom of the high-frequency screen body 1 is fixedly installed with a support plate 13, and a fixing plate 14 is fixedly installed between the two support plates 13.

[0029] Because a support plate 13 is fixedly installed at the bottom of the high-frequency screen body 1, and a fixing plate 14 is fixedly installed between the two support plates 13, the cooperation between the support plate 13 and the fixing plate 14 facilitates stable support for the high-frequency screen body 1, ensuring the stability of the high-frequency screen body 1 during operation.

[0030] A fixing block 16 is fixedly installed on the outer side of the support plate 13, a movable block 18 is movably installed inside the fixing block 16, and a toolbox 17 is fixedly installed on the front of the movable block 18.

[0031] By holding the toolbox 17, the moving block 18 is slowly inserted into the fixed block 16 through the toolbox 17. The fixed block 16 limits and fixes the toolbox 17. By adding the toolbox 17, it is easier for workers to take out and place maintenance tools inside the toolbox 17.

[0032] The inner diameter of the fixed block 16 is equal to the outer diameter of the moving block 18, and the interior of the fixed block 16 has a smooth surface design.

[0033] Because the fixed block 16 has a smooth interior and the inner diameter of the fixed block 16 is equal to the outer diameter of the movable block 18, it is easy to hold the toolbox 17 and slowly insert the movable block 18 into the fixed block 16, thus ensuring the installation efficiency of the toolbox 17.

[0034] A reinforcing rib 15 is fixedly installed at the angle between the support plate 13 and the fixing plate 14, and the reinforcing rib 15 is triangular in shape.

[0035] Since the reinforcing rib 15 is triangular in shape at the angle between the fixed plate 14 and the support plate 13, and triangles have the characteristic of stability, the stability of the support plate 13 and the fixed plate 14 is ensured during use, and the efficiency of the support plate 13 and the fixed plate 14 is improved.

[0036] Working principle and usage process of this utility model:

[0037] After the staff has fixed the curtain 2 between the transmission rod 3 and the welded pipe 5, when it is necessary to lift the curtain 2, the motor 6 is turned on at the bottom of the support base 19 to rotate forward. The motor 6 drives the welded pipe 5 to rotate inside the fixed bracket 20. Now the welded pipe 5 rolls up the curtain 2, and the curtain 2 drives the transmission rod 3 to rotate on the outer surface of the limiting post 4 until the curtain 2 fully unfolds the high-frequency screen body 1. The motor 6 then stops rotating. When it is necessary to cover, the motor 6 is turned on to rotate in reverse. The motor 6 drives the welded pipe 5 to rotate. At this time, the curtain 2 is pushed by the welded pipe 5 to rotate on the outer surface of the limiting post 4 until the top of the high-frequency screen body 1 is completely covered. The motor 6 then stops rotating, thus completing the lifting and covering of the curtain 2.

[0038] Before using the curtain 2, the staff needs to install the curtain 2 on the outer surface of the welded pipe 5 and the limiting strip 8. By holding the pull rod 11, the staff pulls the positioning block 10 inside the transmission rod 3 towards the housing 12. The positioning block 10 compresses the spring 9 inside the housing 12, causing the positioning block 10 to pass through the transmission rod 3 and enter the housing 12. At this time, one end of the curtain 2 is installed on the top of the limiting strip 8. Then, the staff holds the limiting strip 8 and slowly inserts it into the transmission rod 3 and the fixing frame 7. When the limiting strip 8 is fully inserted into the transmission rod 3, the staff releases the pull rod 11. The spring 9 compresses the positioning block 10 inside the housing 12, causing the positioning block 10 to pass through the limiting strip 8. The positioning block 10 limits the limiting strip 8 inside the transmission rod 3 and the fixing frame 7. Then, the staff fixes the other end of the curtain 2 on the outer surface of the welded pipe 5, thus completing the installation of the curtain 2.
