The user can turn the shielding plate to ensure that the shielding plate installation structure is stable. The shielding plate can shield and protect the display screen outside the main control box, avoiding the problem of the display screen outside the main control box being easily stained when placed; the stabilization mechanism can ensure that the connection between the electromagnetic vibration test bench body and the main control box is relatively stable, avoiding the situation of pulling the connecting wire between the electromagnetic vibration test bench body and the main control box, and ensuring the stable operation of the device.

[0004] Objects need to undergo vibration tests during the conveying process. Usually, a vibration table is grafted onto the conveying table. When the conveyed product reaches the position of the vibration table, the upper end surface of the vibration table contacts the product, causing the product to vibrate on the roller conveyor belt, thereby performing a vibration test. However, since the roller conveyor table is directly exposed to the air, dust and debris in the air can easily pass through and enter the bottom wall of the conveyor table. The conveyor table is usually narrow and long, requiring staff to use tools such as long-bristled brushes to deep inside the conveyor table for cleaning, which is relatively inconvenient to operate. Utility Model Content

[0031] The following is combined with Figure 1-5 The utility model is described in further detail.

[0032] The embodiment of the utility model discloses a vibration test table applied to a conveyor belt.

[0033] Reference Figure 1 and Figure 2 A vibration test bench used on a conveyor belt includes a conveyor platform 1. The inner walls on both sides of the conveyor platform 1 are connected to a plurality of roller conveyor belts 2 in a front-to-back symmetrical rotation manner. The outer side of the conveyor platform 1 is fixedly connected to a plurality of driving devices 3 at equal intervals. A vibration test bench 4 is provided on the inner side of the conveyor platform 1. A control panel 5 is provided on the outer side of the conveyor platform 1. The driving device 3 and the vibration test bench 4 are electrically connected to the control panel 5. A cleaning mechanism is provided on the outer side of the conveyor platform 1, and a limiting mechanism is provided on the inner side of the conveyor platform 1.

[0034] When performing a vibration test on a product, the product is first placed on the roller conveyor 2, and then the drive device 3 is started through the control panel 5. The drive device 3 consists of a drive motor, a transmission belt and a belt roller. The drive device 3 drives the roller conveyor 2 to rotate, thereby driving the product to move. When the product moves above the vibration test bench 4, the vibration test bench 4 is started through the control panel 5 to perform a vibration test on the product. After the test is completed, the vibration table descends and the roller conveyor 2 continues to transport the product. The inner bottom wall of the vibration table can be cleaned through the cleaning mechanism to reduce the inconvenience of manual cleaning. The product can be protected by the limiting mechanism to reduce the risk of displacement of the product due to vibration on the roller conveyor 2.

[0035] Reference Figures 2 to 4 The cleaning mechanism includes threaded blocks 9 slidably arranged on both sides of the conveying platform 1, the top of the threaded block 9 is fixedly connected to a top plate 10, a movable plate 11 is slidably arranged inside the top plate 10, a brush 12 is fixedly connected to the bottom of the movable plate 11, and a driving member is provided on the outside of the conveying platform 1.

[0036] Among them, the driving part includes two vertical plates 6 that are fixedly connected to both sides of the conveying platform 1 in a front-to-back symmetrical manner. A rotating motor 7 is fixedly connected to one side of one vertical plate 6. The output shaft of the rotating motor 7 passes through the vertical plate 6 and is fixedly connected to a threaded rod 8. The output shaft of the rotating motor 7 is rotatably connected to the vertical plate 6, and the outer side of the threaded rod 8 is threadedly connected to the threaded block 9.

[0037] In addition, a number of springs 14 are fixedly connected between the top plate 10 and the movable plate 11 at equal intervals. Moving columns 13 are fixedly connected to both sides of the top of the movable plate 11. The moving columns 13 pass through the top plate 10 and are slidably connected to the top plate 10.

[0038] In addition, an auxiliary rod 15 is fixedly connected between the two vertical plates 6 on the other side. The auxiliary rod 15 passes through the threaded block 9 and is slidably connected to the threaded block 9.

[0039] In addition, a cleaning hole 16 is provided on the inner bottom wall of the conveying platform 1 , and a storage slot is provided on the conveying platform 1 . A cleaning box 17 is slidingly provided inside the storage slot, and an opening is provided on the top of the cleaning box 17 , and the opening of the cleaning box 17 is adapted to the cleaning hole 16 .

[0040] When cleaning the inner bottom wall of the conveying platform 1, the rotating motor 7 is first started to drive the threaded rod 8 to rotate. The threaded rod 8 is threadedly connected to the threaded block 9, so that the threaded block 9 moves horizontally on the outer side of the threaded rod 8. When the threaded block 9 moves, it drives the top plate 10 to move. The movement of the top plate 10 drives the moving plate 11 to move. The movement of the moving plate 11 causes the brush 12 to clean the inner wall of the cleaning platform, thereby realizing the process of automatically cleaning the inner bottom wall of the conveying platform 1, reducing the inconvenience of manual cleaning, and thus reducing labor intensity.

[0041] When cleaning the inner bottom wall of the conveyor platform 1, the spring 14 between the movable plate 11 and the top plate 10 is in a certain compressed state, ensuring that the brush 12 is always in close contact with the inner bottom wall, increasing the friction between the brush 12 and the inner bottom wall, and more effectively removing stubborn stains and attachments, ensuring thorough cleaning;

[0042] When the top plate 10 moves, the auxiliary rod 15 provides a guide for the top plate 10 so that the top plate 10 can remain stable during movement;

[0043] When the brush 12 is cleaning, the brush 12 will drive the dust and debris into the cleaning hole 16, and then communicate with the cleaning box 17 through the cleaning hole 16, so that the dust is stored in the cleaning box 17, which is convenient for the staff to clean the dust and debris later.

[0044] Reference Figure 2 and Figure 5The protective mechanism includes a horizontal plate 18 fixedly connected to the inner side of the conveying platform 1, an electric push rod 19 fixedly connected to the top of the horizontal plate 18, an output shaft of the electric push rod 19 fixedly connected to a protective plate 20, and a protective pad fixedly connected to the side of the protective plate 20 close to the vibration test table 4.

[0045] When the product is vibrated, the protective plate 20 is driven upward by starting the electric push rod 19, thereby limiting the two sides of the product. The limited product is constrained by the protective plate 20 during the vibration process. The limiting effect of the protective plate 20 can effectively prevent the product from falling from the vibration table. Since the protective block 21 is made of rubber, the impact when the product collides with the protective plate 20 can be reduced, thereby providing certain protection for the protective plate 20.

[0046] Working principle: Place the product on the roller conveyor 2, and then start the driving device 3 through the control panel 5. The driving device 3 consists of a driving motor, a transmission belt and a belt roller. The driving device 3 drives the roller conveyor 2 to rotate, thereby driving the product to move. When the product moves to the top of the vibration test bench 4, the vibration test bench 4 is started through the control panel 5 to perform a vibration test on the product. The rotating motor 7 is started to drive the threaded rod 8 to rotate. The threaded rod 8 is threadedly connected to the threaded block 9, so that the threaded block 9 moves horizontally on the outside of the threaded rod 8. When the threaded block 9 moves, it drives the top plate 10 to move, and the top plate 10 moves. The movement will drive the movable plate 11 to move, and the movement of the movable plate 11 will enable the brush 12 to clean the inner wall of the cleaning table; when cleaning the inner bottom wall of the conveying table 1, the spring 14 between the movable plate 11 and the top plate 10 is in a certain compression state, ensuring that the brush 12 is always in close contact with the inner bottom wall, increasing the friction between the brush 12 and the inner bottom wall, and starting the electric push rod 19 to drive the protective plate 20 to move upward, thereby limiting the two sides of the product. After limiting, the product is constrained by the protective plate 20 during the vibration process. The limiting effect of the protective plate 20 can effectively prevent the product from falling from the vibration table.
