Description

Technical Field

[0001] The utility model relates to the field of block forming equipment, in particular to a vibration system. Background Art

[0002] The applicant applied for a patent application numbered 202111620763.2 on December 28, 2021. The patent name is a vibration system for a block forming machine, which discloses in detail a frame, a vibration table, several servo motors, a balancing vibration mechanism, a universal joint coupling, a left vibration mechanism and a right vibration mechanism. The vibration table is arranged on the upper part of the frame, and the left vibration mechanism and the right vibration mechanism are symmetrically distributed on the lower part of the vibration table. At least three groups of independent vibration components are arranged side by side in the left vibration mechanism and the right vibration mechanism. , each of the servo motors is connected to each vibration component through a balancing vibration mechanism and a universal joint coupling, and then drives each vibration component to rotate, so as to realize the resonance of the left vibration mechanism and the right vibration mechanism. By setting up a separated left vibration mechanism and a right vibration mechanism distributed on the left and right sides of the vibration table, and the left vibration mechanism and the right vibration mechanism are both provided with four independent vibration components, the rotating shaft of the vibration component can be shortened, so as to avoid the vibration or bending of the rotating shaft of the vibration component during high-speed operation, and then increase the rotation speed of a single vibration component, so as to increase the vibration frequency. However, in actual use, since the universal joint coupling is used to connect the servo motor and the vibration component, the universal joint coupling has a processing error, so that there is a deviation in the rotation angle between the output shaft of the servo motor and the vibration shaft of the vibration component. Therefore, there is an error in the angle of rotation of the vibration shaft of the vibration component driven by the servo motor in the control system, which causes the vibration frequency of each vibration component to be inconsistent with the design frequency, and then causes the quality of the molded product to be relatively poor.

[0003] Therefore, the applicant applied for a patent application number 202320120474.4 on January 15, 2023. The patent name is a vibration component, which improves the above-mentioned technical problems and specifically discloses that a box body is fixed on a frame, and a first rotating shaft is rotatably arranged in the box body. The two ends of the first rotating shaft are respectively connected to the output shaft and the second rotating shaft of the servo motor, and the first rotating shaft and the second rotating shaft, and the second rotating shaft and the vibration shaft are connected by a first connecting member, a second connecting member, an elastic pad and a bolt locking connection, so that the output shaft of the servo motor and the vibration shaft are directly connected, avoiding the gap in the connection, which causes the deviation of the rotation angle, so that the control system can accurately control the vibration coordination of the servo motor and the vibration mechanism, thereby improving the quality of the molded product. At the same time, through the setting of the box body and the first rotating shaft, the connecting component is fixed, so that when the distance between the servo motor and the vibration shaft is required, the stability of operation is guaranteed, thereby improving the durability of the equipment and increasing the service life.

[0004] However, by rotatably arranging a first rotating shaft on the housing to connect the second rotating shaft and the servo motor, and then connecting the second rotating shaft to the vibration shaft, the excess vibration on the vibration shaft can be removed through the first rotating shaft, thereby reducing the influence of the vibration on the servo motor. However, not only the servo motor and the second rotating shaft need to be installed with high precision, but the housing and the first rotating shaft also need to be installed with high precision so that the control system can accurately control the vibration coordination between the servo motor and the vibration mechanism, resulting in high manufacturing costs and a relatively complex structure. Utility Model Content

[0008] Furthermore, the motor mounting base includes a base plate and a vertical plate vertically arranged on the base plate, the vertical plate is distributed on one longitudinal side close to the vibration box, the vertical plate is provided with a through hole for the output shaft of the driving motor to pass through, the front end of the driving motor is locked on the vertical plate by bolts, and the shock absorbing assembly is arranged between the driving motor and the base plate.

[0009] Furthermore, reinforcing ribs are provided on the connection between the vertical plate and the bottom plate.

[0010] Furthermore, the shock-absorbing assembly includes a support plate fixed to the bottom of the driving motor, a mounting hole provided on the support plate, a threaded rod passing through the mounting hole, an upper nut and a lower nut threadedly connected to the threaded rod and respectively distributed on the upper and lower sides of the support plate, and an elastic pad provided at the lower end of the threaded rod.
