Abstract

The utility model provides a simple-structured novel vibrating device for a building block machine comprising a vibrating platform, a servo controller, four servo motors and four eccentric shafts. Of the four eccentric shafts, each two form a group, every two eccentric shafts in a group are arranged symmetrically under the vibrating platform, in which two servo motors are arranged on one transverse side of the vibrating platform and are in transmission connection with one group of the eccentric shafts, the other two servo motors are arranged on the other transverse side of the vibrating platform and are in transmission connection with the other group of the eccentric shafts, and each servo motor is electrically connected with the servo controller. Because one servo controller is adopted to control a plurality of servomotors simultaneously, the output of each servo motor is strictly in-phase, so that each eccentric shaft that is connected with an output end of each servomotor is strictly in-phase, thus not only simplifying the structure, but also making the vibrating platform, the splint and the molding box vibrate by strict one dimension, and largely improving the lives of the vibrating platform, the splint and the molding box and the quality of the building block.

Description

A kind of novel type block machine vibrator

Technical field

The utility model relates to a kind of building block machine, particularly a kind of novel type block machine vibrator.

Background technology

The building block machine has been known, it generally comprises frame, moulding box, feeding trolley, pressure head, vibrating device, stripper apparatus etc., feeding trolley is sent into concrete in the moulding box, vibrating device carries out jolt ramming to the concrete in the moulding box, pressure head is concrete compression moulding then, the finally demould device the building block demoulding of forming on the supporting plate above the vibrating device.Known vibrating device generally comprises two rotating shafts and is located at the eccentric block of two identical weight in the rotating shaft respectively, and by the synchromesh gear engaged transmission, the axial end of a rotating shaft wherein is provided with by motor-driven belt pulley between two rotating shafts.When belt pulley rotated under the motor effect, two rotating shafts were rotated under the effect of synchromesh gear like this, did the synchronous backward rotation thereby be located at two eccentric blocks in the rotating shaft, and then produced exciting up and down.Because the size of moulding box is bigger, need many group eccentrically weighted shafts to carry out exciting like this, corresponding needs are organized meshing gear more and are driven, and whole transmission mechanism is complicated heavy, requires powerful drive motors to drive, and equipment cost and operation cost are all very high.

The utility model content

The purpose of this utility model is to provide a kind of novel type block machine vibrator simple in structure, with low cost.

The technical scheme that the utility model adopted is such: a kind of novel type block machine vibrator, the involving vibrations platform, servo controller, four servo motors and four eccentrically weighted shafts, per two of described four eccentrically weighted shafts are one group, two eccentrically weighted shafts of each group are symmetrically set in the shaking platform below, wherein two servo motors are located at the horizontal side of shaking platform and are in transmission connection with one group of eccentrically weighted shaft wherein respectively, other two servo motors are located at the horizontal opposite side of shaking platform and are in transmission connection with other one group of eccentrically weighted shaft respectively, and each servo motor is electrically connected with servo controller.

Above-mentioned novel type block machine vibrator, described each eccentrically weighted shaft are made up of rotating shaft and some eccentric blocks of being located on the same phase place of rotating shaft respectively, and the eccentric block of two rotating shafts on same group of eccentrically weighted shaft on it is symmetrical arranged.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: control four servo motors simultaneously by a servo controller, the output of each servo motor is synchronously strict, make that four eccentrically weighted shafts that are connected with each servo motor output are synchronously strict, thereby can under the situation that guarantees equal exciting force, reduce the power of servo motor greatly, because shaking platform, supporting plate and moulding box can be kept strict one dimension vibration, the flexural deformation that two-dimension vibration causes can not appear, thereby the service life that can improve the platform that shakes, supporting plate and moulding box greatly, cut operating costs; This structure is saved the many groups meshing gear in the known vibratory apparatus in addition, reduces rotary inertia, helps the startup and the braking of vibrating device, and then avalanche when avoiding the building block demoulding.

The specific embodiment

With reference to figure 1, Fig. 2, embodiment discloses a kind of novel type block machine vibrator, its involving vibrations platform 1, four eccentrically weighted shafts 2, servo controller (not shown) and four servo motors 3, described shaking platform 1 is consistent with known shaking platform, it is located at the below of building block machine moulding box and supporting plate, it carries out jolt ramming for the concrete in the moulding box indirectly by supporting plate, 2 per two one group of described four eccentrically weighted shaft are as a pair of below of being located at shaking platform 1 respectively symmetrically, each eccentrically weighted shaft 2 is made up of rotating shaft 21 and four eccentric blocks 22 being located in the rotating shaft 21, four eccentric blocks 22 are positioned at the same phase place of rotating shaft 21, for shaking platform 1 is produced maximum exciting force, two rotating shafts 21 of every pair of eccentrically weighted shaft 2 are symmetrically set in the below of shaking platform 1, and with the phase place of two rotating shafts 21 of a pair of eccentrically weighted shaft 2 eccentric block 22 on it symmetry just, wherein two servo motors 3 are located at shaking platform 1 a horizontal side and are in transmission connection by shaft coupling 23 and one group of eccentrically weighted shaft 2 wherein respectively, described each servo motor 3 is in transmission connection by shaft coupling 23 and each rotating shaft 21 respectively, other two servo motors 3 are located at shaking platform 1 horizontal opposite side and are in transmission connection with other one group of eccentrically weighted shaft 2 respectively, each servo motor 3 is electrically connected with same servo controller (not shown) respectively, what each servo motor 3 received like this is the power supply of same frequency, and each servo motor 3 is with same speed, same turning to drives each eccentrically weighted shaft 2 rotation.Because servo motor 3 is oppositely arranged, thereby in four rotating shafts 21, having two just then two counter-rotatings, and the eccentric block phase place on two groups of eccentrically weighted shafts 2 is arranged on the position of symmetry, and then drive the exciting force that each eccentric block 22 produces maximum, shaking platform 1 is carried out exciting.

Need to prove, the utility model shaking platform below can be provided with eight eccentricity excitation points, the exciting point of the platform that shakes is distributed rationally, the platform of guaranteeing to shake can strictness be done the one dimension forced vibration, each eccentricity excitation point that thinking is set is consistent with the aforementioned techniques scheme, so that the maximum exciting force of generation under the driving of servo motor, therefore the eccentric block phase place in necessary setting in pairs of described eccentricity excitation point and the corresponding rotating shaft is just opposite.
