Description

Technical Field

[0001] The invention relates to a component of a cement brick block forming machine, in particular to a vibration box of the block forming machine. Background Art

[0002] Conventional cement brick forming machines feature a vibration box structure with a row of eccentric shafts installed at the bottom of a platform. However, small machines can only accommodate two eccentric shafts. Furthermore, this design only provides platform vibration, not die vibration. Excessive eccentricity can easily lead to shaft breakage, and high amplitude vibrations can produce poor vibration effects. If the eccentric shafts are too small, the vibration is often insufficient, and platform vibration will never achieve the same effect as die vibration. Synchronous platform and die vibration is also impossible. Summary of the Invention

[0003] The object of the present invention is to solve the above problems and provide a vibration box for a block forming machine with good vibration effect.

[0004] To achieve the above-mentioned purpose of the present invention, the present invention provides a vibration box for a block forming machine, including a box body, which is divided into four directions: front, rear, left and right, wherein the front and rear directions are provided with short eccentric shafts, and the left and right directions are provided with long eccentric shafts. A through hole for mounting a mold is provided in the middle of the box body, and a first bearing seat and a second bearing seat are provided in the front and rear symmetrical directions of the mounting through hole. The first bearing seat and the second bearing seat are provided with multiple short eccentric shafts connected, and a third bearing seat and a fourth bearing seat are provided on the left and right sides. The third bearing seat and the fourth bearing seat are provided with multiple long eccentric shafts connected, and the long directions of the long eccentric shafts are connected by a universal connector, and the long eccentric shafts and the short eccentric shafts are provided with synchronous gears and bearings, and the long eccentric shafts and the short eccentric shafts are connected to each other by synchronous gears to form synchronization, along the front and rear directions of the box body, two or four short eccentric shafts are symmetrically provided on the outer side near the inner side of the left and right long eccentric shafts, extending out of the box body, and a pulley is provided to drive the motor pulley to generate synchronous vibration.

[0005] According to one aspect of the present invention, the vibration box of the block forming machine can be used as the upper mold vibration or the lower mold vibration. The vibration boxes of the block forming machine are configured on the upper and lower sides, and the table mold can be vibrated synchronously.

[0006] According to one aspect of the present invention, a spacer layer for passing bolts for fixing the mold is provided above and below the box body, and a support plate for fixing the block mold is provided above and below the spacer layer.

[0007] The width of the upper support plate is greater than that of the lower support plate.

[0008] According to one aspect of the present invention, the first bearing seat, the second bearing seat, the third bearing seat and the fourth bearing seat are connected to the housing by bolts.

[0009] The vibration box of the block forming machine of the present invention has a simple and compact structure, is easy to use, simple to maintain and has a good vibration effect. The block mold can be placed in the installation through hole to achieve mold vibration, and a platform can be installed on the top to achieve table vibration.

[0010] The vibration box of the block forming machine of the present invention is provided with a rectangular or square through hole for installing the mold in the middle of the box body, which is used to install the block mold. After the mold is installed, the synchronous gears and eccentric shafts arranged around it, and the four eccentric shafts on the outermost sides of the front and back, close to the left and right, extend out of the box body. The eccentric shafts are driven by the motor pulley to move, thereby achieving the synchronous vibration of the eccentric shafts arranged around it through the synchronous gears. Its vibration force directly generates vibration uniformly around the mold. Such a design can produce an excellent vibration effect. The present invention is direct vibration. The vibration principle of the traditional table vibration is that the vibration force generated by the vibration box is then transmitted to the mold. The vibration effect of the vibration force will be reduced during the transmission process. The vibration force of the present invention will not be reduced due to consumption caused by the transmission of vibration. The use of the present invention can achieve energy-saving effects.
