Problems solved by technology
Due to the large size of the mold box, multiple sets of eccentric shafts are required for excitation, and correspondingly multiple sets of meshing gears are required for driving. The entire transmission mechanism is complex and heavy, requiring a high-power drive motor to drive, and the equipment cost and operating cost are very high. high

Embodiment Construction
[0009] Referring to Fig. 1 and Fig. 2, the embodiment discloses a new type of vibration device for a block machine, which includes a vibration platform 1, four eccentric shafts 2, a servo controller (not shown in the figure) and four servo motors 3, the The vibrating platform 1 is consistent with the known vibrating platform. It is arranged under the block machine mold box and the supporting plate. It indirectly vibrates the concrete in the mold box through the supporting plate. The four eccentric shafts 2 every two One group is symmetrically arranged under the vibration platform 1 as a pair, each eccentric shaft 2 is composed of a shaft 21 and four eccentric blocks 22 arranged on the shaft 21, and the four eccentric blocks 22 are located at the same phase of the shaft 21, In order to generate the maximum exciting force on the vibrating platform 1, the two rotating shafts 21 of each pair of eccentric rotating shafts 2 are arranged symmetrically below the vibrating platform 1, a...

The invention provides a new vibration device with a simple structure for a block-making, which comprises a vibration platform, a servo controller, four servo motors and four eccentric shafts. Each two eccentric shafts are in a group and each two eccentric shafts are symmetrically arranged on the lower part of the vibration platform, wherein, two servo motors are arranged on the horizontal side of the vibration platform and are respectively transmission connected with one group of the eccentric shaft, another two servo motors are arranged on the other horizontal side of the vibration platform and are respectively transmission connected with the another group of the eccentric shafts. The servo motors are electrically connected with the servo controller. As a servo controller synchronously controls a plurality of servo motors, the outputting of all the servo motors are toughly synchronous in order to lead al the eccentric shafts to connect with the outputting end of all the servo motors in a tough synchronization way, thus not only simplifying the structure, but also leading the vibration platform, splint and die box to strictly generate a one dimensional vibration, therefore, the service life of the vibration platform, the splint and the die box is prolonged and the block quality is greatly promoted.
Description
technical field [0001] The invention relates to a block machine, in particular to a novel vibration device of the block machine. Background technique [0002] The Chinese patent CN2878009 announced on March 14, 2007 discloses a new type of online amplitude modulation vibration device for block machines. The revolving shaft, gear, shift fork and eccentric block are installed in the box, the gear is installed on the revolving shaft through the transmission coupling, the eccentric block is installed on the vibrating shaft at the end of the revolving shaft, and the power input coupling is connected to the extended end of the revolving shaft. The shift fork is connected with the gear and is connected with the linear drive mechanism arranged outside the box. Although this kind of vibrating device can realize online amplitude modulation, its structure is particularly complicated and maintenance is inconvenient. Generally speaking, the known vibrating device includes two rotating ...
