Under the action of gravity, the bottom end of the movable plate in the movable structure is always in contact with the eccentric wheel; as the output shaft rotates, the distance between the axis of the output shaft and the contact point between the eccentric wheel and the movable plate will continuously change with the rotation of the eccentric wheel. Therefore, the movable plate will move up and down with the change of the distance between the axis of the output shaft and the contact point, thereby converting the rotation of the output shaft into the up and down movement of the movable plate. The eccentric wheel is driven to move up and down along the slide rail, thereby driving the movable platform to move up and down, realizing the vibration function. Compared with the existing technology, the structure of the utility model is simpler and the cost is lower.

[0047] Example 1

[0048] This embodiment provides a vibration device, such as Figures 1 to 3 As shown, it includes a base frame 1, a moving structure 3 and a driving structure 4.

[0049] The base frame 1 includes a base 11 and a fixing plate 12. The base 11 is horizontally arranged and the fixing plate 12 is vertically fixed to the middle position of the base 11. A set of slide rails 2 includes two slide rails 2. A set of slide rails 2 is vertically mounted on the fixing plate 12, and the two slide rails 2 are spaced apart.

[0050] like Figures 1 to 3 As shown, the movable structure 3 includes a movable plate 31 and a movable platform 33. Two movable parts 32 are fixed on the rear side of the movable plate 31 corresponding to the two slide rails 2. A slide groove is provided on the rear side of the movable part 32. The slide groove is clamped on the slide rail 2 to vertically set the movable part 32. The movable platform 33 is horizontally installed on the top of the movable part 32. The movable platform 33 is in a pie shape and is arranged perpendicular to the movable part 32.

[0051] like Figures 1 to 3 As shown, the driving structure 4 includes a driving member 41 and an eccentric wheel 42. The driving member 41 is a reduction motor. The driving member 41 is installed on the top surface of the base 11 and the driving member 41 is installed on the rear side of the fixed plate 12 away from the slide rail 2. The output shaft of the driving member 41 passes through the fixed plate 12 and extends to the front end where the slide rail 2 is provided. The eccentric wheel 42 is installed at the end of the output shaft on the front side of the fixed plate 12. In order to ensure the installation stability between the output shaft and the eccentric wheel 42, a first groove is provided on the outer surface of the output shaft, and a second groove is provided in the inner hole of the eccentric wheel 42 corresponding to the first groove. When installing, it is necessary to ensure that the opening of the first groove is arranged relative to the opening of the second groove. The vibration device also includes an interference washer 5. The interference washer 5 can be inserted into the installation hole to fix the output shaft and the eccentric wheel 42 to ensure that there is no radial sliding between the two and to ensure that the subsequent work process is not disturbed.

[0052] like Figures 1 to 3As shown, the rear side of the eccentric wheel 42 close to the fixed plate 12 is parallel to the front side of the fixed plate 12 close to the eccentric wheel 42, and the distance between the two sides is a first distance. The distance between the front side of the slide rail 2 away from the fixed plate 12 and the front side of the fixed plate 12 close to the eccentric wheel 42 is a second distance. The first distance is greater than the second distance to ensure that the eccentric wheel 42 does not touch the slide rail 2 during rotation, thereby avoiding interference. In addition, the fixed plate 12 is provided with a through groove 111 directly below the eccentric wheel 42, which avoids interference while reducing the volume of the entire device.

[0053] When the vibration device is vibrating, the driving member 41 is started, and the driving member 41 drives the eccentric wheel 42 to rotate through the output shaft. Under the action of gravity, the bottom end of the movable plate 31 in the movable structure 3 is always in contact with the eccentric wheel 42; as the output shaft rotates, the distance between the axis of the output shaft and the contact point between the eccentric wheel 42 and the movable plate 31 will change continuously with the rotation of the eccentric wheel 42, so the movable plate 31 will move up and down with the change of the distance between the axis of the output shaft and the contact point, thereby converting the rotation of the output shaft into the up and down movement of the movable plate 31. The eccentric wheel 42 is driven to move up and down along the slide rail 2, thereby driving the movable platform 33 to move up and down, realizing the vibration function. Compared with the prior art, the structure of the utility model is simpler and the cost is lower. Moreover, the entire device only requires a reduction motor with low noise, which reduces the cost.

[0054] In this embodiment, if Figures 1 to 3 As shown, the vibration device further includes a vibration-damping pad 6, which is installed at the bottom end of the base 11 to alleviate the vibration of the entire device, reduce the shaking of the device, and further reduce noise.

[0055] Specifically, the base 11 has a length and width of 564 mm and 400 mm, respectively. When the eccentric wheel 42 drives the movable platform 33 to its highest position, the entire device is 404.5 mm high. When the eccentric wheel 42 drives the movable platform 33 to its lowest position, the entire device is 349.5 mm high. Compared with the existing technology, the structural dimensions are greatly reduced.

[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
