Description

Technical Field

[0001] The utility model relates to the technical field of brick-making equipment, and particularly relates to a vibrating table driven by a servo motor. Background Art

[0002] During the brick-making process, after the material is laid in the brick mold, the brick is then pressed into shape by a pressing head assembly. During the process of the pressing head assembly pressing the brick, it is necessary to vibrate the material in the brick mold so that the material can be evenly laid in the brick mold, thereby enabling the pressing head assembly to better press the brick into shape. The public number of the Chinese Patent Network is: CN202320221969.6, which discloses the dynamic and static vibrating table developed by our company. Although it can meet the usage requirements, problems are found during the usage process. The power mechanism of the vibration mechanism uses a common vibration motor to drive the pulley to rotate, and then drives the eccentric shaft in the vibration box to rotate. Although it can meet the usage, the rotational speed of the common vibration motor is only more than 2000 revolutions, so the vibration effect is not ideal, the required vibration time is long, resulting in high energy consumption, and the belt drive is prone to slipping, further leading to poor working efficiency of the vibrating table.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Refer to Figures 1-4, what is disclosed in the embodiment of the present utility model is: a vibration table driven by a servo motor, including a vibration table body 1, a vibration box 2 provided on the vibration table body 1, and a servo motor 6. The servo motor 6 is provided on an external frame. A first synchronous pulley 4 is provided on the servo motor 6. A second synchronous pulley 3 is provided on the drive shaft 21 of the vibration box 2. A synchronous belt 5 is wound between the first synchronous pulley 4 and the second synchronous pulley 3. Among them, the use of a servo motor 6 and synchronous pulleys enables servo control. The rotational speed of the servo motor 6 can reach more than 4000 revolutions per minute instantly, so that the vibration effect can reach the peak instantly, making the vibration better, saving energy, and the use of the servo motor 6 can reduce the generation of noise, which is beneficial to green production. At the same time, the use of a synchronous belt 5 for transmission can better prevent slipping and further enable better vibration.

[0023] In order to facilitate the replacement of the synchronous belt 5, it further includes a connecting shaft 31, two fixing blocks 9, and a screw rod 8. The second synchronous pulley 3 is provided on the connecting shaft 31. The connecting shaft 31 is sleeved on the drive shaft 21. Two sliding channels 7 are opened in the connecting shaft 31 to match the fixing blocks 9. The fixing blocks 9 are slidably provided in the sliding channels 7. A fixing channel is opened at the position of the connecting shaft 31 where the sliding channels 7 are located. The screw rod 8 is rotatably passed through the connecting shaft 31. One end of the screw rod 8 is in threaded transmission with the fixing block 9, and the other end of the screw rod 8 passes out of the connecting shaft 31. The fixing block 9 is a square block so that the screw rod 8 can drive the fixing block 9 to slide linearly. Among them, when the synchronous belt 5 is worn or broken and needs to be replaced, rotate the screw rod 8. The screw rod 8 is in threaded transmission with the fixing block 9, so that the fixing block 9 slides into the sliding channel 7, releasing the engagement with the fixing channel. Then remove the second synchronous pulley 3. Then put on a new synchronous belt 5. Then directly sleeve the connecting shaft 31 onto the drive shaft 21. Then reverse the screw rod 8. The screw rod 8 is in threaded transmission with the fixing block 9, so that the fixing block 9 is engaged in the fixing channel and the sliding channel 7, thus completing the replacement, which is simple, convenient and fast.

[0024] In order to enable better connection between the connecting shaft 31 and the drive shaft 21, an elastic rubber layer 10 is provided on the inner wall of the fixing channel. The front end of the fixing block 9 is provided with an inclined surface, and the fixing channel is arranged to match the inclined surface of the fixing block 9.
