Description

Technical Field

[0001] The utility model belongs to the technical field of vibration equipment, and particularly relates to a transmission shaft directly connected vibrator. Background Art

[0002] A vibrator is a device used to produce a high-frequency, micro-amplitude vibration effect. It is commonly used in brick machine equipment, concrete block forming equipment, concrete mixing equipment, etc. Under the effect of vibration, concrete and brick mixtures are vibrated and compacted to ensure product quality and improve product forming efficiency. Existing vibrators are generally eccentric vibrators driven by motors. Under the driving action of the motor, the rotating shaft drives the eccentric vibrator to rotate and produce vibration. In terms of transmission mode, a belt is usually used between the output shaft of the motor and the rotating shaft of the eccentric vibrator for transmission.

[0003] When this type of vibrator is applied to equipment such as brick machines, the following problems exist: First, the belt drive method usually requires that the output shaft of the drive motor be misaligned with the rotating shaft of the eccentric vibrator, which causes the vibrator to take up more space. For brick machine equipment, etc., since only a flat installation space is usually reserved for the vibrator, the vibrator cannot be installed smoothly; secondly, the vibration position of the existing vibrator is relatively single, and some application scenarios require a relatively uniform vibration effect within a surface area. For example, when pressing and forming unfired bricks, it is necessary to provide a relatively uniform vibration effect in the mold area where the bricks are located. Regardless of whether the vibrator is installed in the center or the outer edge of the mold, it is difficult to produce the aforementioned uniform vibration effect. In summary, it is necessary to develop and design a new type of vibrator equipment to solve the aforementioned technical problems. Utility Model Content

[0006] Preferably, a spline is provided on the outer wall of the output shaft of the servo motor and a matching spline groove is provided on the inner wall of the outer sleeve; a spline is provided on the outer wall of the outer end of the rotating shaft and a matching spline groove is provided on the inner wall of the inner sleeve.

[0011] The advantages and positive effects of the utility model are:

[0012] The utility model provides a transmission shaft direct-connected vibrator with a reasonable structural design. Compared with the existing vibrators, the vibrator in the utility model is a planar, array-type vibrator composed of multiple vibrating modules. Since the output shaft of the servo motor and the rotating shaft of the eccentric vibrator are directly connected by a transmission shaft, the output shaft of the servo motor and the rotating shaft of the eccentric vibrator do not need to be misaligned. Therefore, the direct-connected vibrator of the utility model is a flattened vibrator, which can be installed in a flat and narrow space reserved on the equipment, which is beneficial to the structural design of the equipment.

[0013] On the other hand, the multiple transmission boxes and eccentric vibrators of the multiple vibration modules of the direct-connected vibrator of the utility model provide relatively uniform vibration effects within a certain surface area through an array-type vibration component. For example, when installed on a brick machine equipment that produces unfired bricks, it can provide a surface-type vibration effect for the brick-making pressing mold, thereby ensuring the quality of product processing by providing a uniform vibration effect.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0020] See also Figure 1 The drive shaft direct-connected vibrator of the utility model comprises a plurality of vibrating modules arranged in parallel, and the plurality of vibrating modules are installed in an array type to form a plane type and array type vibrator.

[0021] See also Figure 2 and Figure 3 , we can see that:

[0022] The vibrating module includes a mounting base plate 1, on which two left and right transmission boxes 2 with rotating shafts 2-3 are mounted, and eccentric vibrators 5 are mounted at the two exposed ends of the rotating shafts 2-3. A servo motor 4 is arranged on the outside of each transmission box 2, and the output shaft of the servo motor 4 is directly connected to the outer end of the rotating shaft 2-3 by a transmission shaft 3. Since the transmission shaft 3 is used for direct connection, the output shaft of the servo motor 4 and the rotating shaft 2-3 do not need to be misaligned (that is, the output shaft of the servo motor 4 and the center line of the rotating shaft 2-3 are approximately collinear), which ensures that the direct-connected vibrator has a flattened structural feature, so it can be installed and used in a flat and narrow space reserved on the equipment, which is conducive to the compact design of the equipment structure.

On the other hand, since the outer sleeve 3-1 and the output shaft of the servo motor 4 are splined, and the inner sleeve 3-5 and the rotating shaft 2-3 are splined, during the transmission process, the outer sleeve 3-1 and the output shaft of the servo motor 4, and the inner sleeve 3-5 and the rotating shaft 2-3 can be relatively positioned in the axial direction, which further ensures the reliability and effectiveness of the transmission, avoiding the problem of transmission jam.

This installation method is convenient for selecting and replacing the eccentric vibrator 5.

[0028] In this embodiment, the mounting base plate 1 includes two base plate monomers and the two base plate monomers are respectively located below the two transmission boxes 2, and mounting holes are provided on the edges of the base plate monomers.
