Technical Field

[0001] This utility model belongs to the field of vibration equipment technology, and in particular relates to an electrically driven vibration device for a block forming machine. Background Technology

[0002] A block molding machine is a molding equipment for processing blocks. It is a machine that uses materials such as fly ash, river sand, gravel, stone powder, fly ash, waste ceramsite slag, and smelting slag, with a small amount of cement added, to produce new wall material blocks. The block molding machine adopts a hydraulic molding working mode, combined with the vibration effect provided by a vibration device. The vibration effect has a significant impact on the quality of the block molding. The vibration device configured in existing block molding machines usually includes a vibration box and a vibration motor. The vibration box contains a drive shaft, an eccentric vibrating block, and a transmission gear. The vibration motor drives the eccentric vibrating block to rotate, providing the vibration effect for the block molding machine. The aforementioned vibration device has the following problems: First, the overall structure is complex and occupies a lot of space, requiring the processing and assembly of multiple components such as the box, drive shaft, and transmission gear; second, the single motor drive mode results in an unsatisfactory vibration effect, i.e., insufficient vibration intensity.

[0003] In summary, it is necessary to develop and design a new type of electrically driven vibration device to solve the aforementioned technical problems and meet the usage requirements of block molding machines. Summary of the Invention

[0004] The purpose of this invention is to provide an electrically driven vibration device for a block forming machine, which has a simple structure, occupies little space, and has high vibration intensity.

[0005] The technical solution adopted by this utility model is as follows: an electric drive vibration device for a block molding machine, including a supporting vibration table, on which a front first motor and a front second motor, as well as a rear first motor and a rear second motor, are fixed with a common center line. The center lines of the front first motor and the rear first motor are parallel. Eccentric vibration blocks are installed on the rotating shafts of the front first motor, the front second motor, the rear first motor, and the rear second motor. A front synchronous gear that connects the two rotating shafts is installed between the rotating shafts of the front first motor and the front second motor, and a rear synchronous gear that connects the two rotating shafts is installed between the rotating shafts of the rear first motor and the rear second motor. A linkage component is provided between the front synchronous gear and the rear synchronous gear. The linkage component is detachably connected to the supporting vibration table, and the rotation directions of the front synchronous gear and the rear synchronous gear are opposite.

[0006] Preferably, the front first motor, the front second motor, the rear first motor, and the rear second motor are all dual-head motors, and eccentric vibrating blocks are installed at both ends of the rotating shaft.

[0007] Preferably, keyways are provided in the shaft holes of both the front and rear synchronous gears, and the shafts of the front first motor and the front second motor are keyed to the front synchronous gear, and the shafts of the rear first motor and the rear second motor are keyed to the rear synchronous gear.

[0008] Preferably, the linkage assembly includes a base, on which a detachable and meshing first linkage gear and a second linkage gear are mounted. The first linkage gear meshes with a front synchronous gear, and the second linkage gear meshes with a rear synchronous gear.

[0009] Preferably, the base of the linkage assembly includes a top plate with a window in the middle, and two opposing side plates at the bottom of the top plate. The first linkage gear and the second linkage gear are located between the two side plates, and the shaft end of the first linkage gear is mounted on the side plate using a first bearing, and the shaft end of the second linkage gear is mounted on the side plate using a second bearing.

[0010] Preferably, the top plate of the linkage assembly is provided with three sets of mounting holes (front, middle, and rear) and each set of mounting holes is provided with an assembly screw. The corresponding positions on the support vibrating table are provided with three sets of threaded holes (front, middle, and rear), and the lower end of the assembly screw is located in the threaded hole.

[0011] Preferably, the first and second linkage gears of the linkage assembly are wearable nylon gears.

[0012] The advantages and positive effects of this utility model are:

[0013] This utility model provides an electric drive vibration device for a block molding machine. Compared with existing electric drive vibration devices, this utility model adopts a structure of direct motor drive of eccentric vibrating blocks and uses four identical motors to generate vibration drive at the same time. This structure firstly eliminates the need to install a vibration box, thus simplifying the overall structure and reducing space occupation. At the same time, the fewer components improve the overall reliability during operation. The simultaneous drive of multiple motors can enhance the intensity of the vibration effect generated by this electric drive vibration device, meeting the usage requirements of the block molding machine.

[0014] This electrically driven vibration device uses a linkage assembly installed between the front and rear synchronous gears of two sets of drive motors to force the two sets of drive motors and their synchronous gears to rotate synchronously in opposite directions. The linkage effect generated by the linkage assembly keeps the rotation of each eccentric block synchronized, avoiding the problem of weakened vibration effect caused by asynchronous rotation. On the other hand, by making the linkage assembly detachable from the support vibration table, it can be quickly and easily replaced and maintained after the linkage assembly wears out, allowing this electrically driven vibration device to maintain its operating characteristics for a long time.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0021] Please see Figure 1 The electric drive vibration device of the block forming machine of this utility model includes a support vibration table 1. The support vibration table 1 serves as a bearing platform for other components. The support vibration table 1 is installed on the main body of the block forming machine by means of welding, strong bolt connection, etc. The vibration generated is applied to the main body of the machine, and the necessary vibration is applied during the hydraulic forming of the block to promote the forming of the block.

[0022] A front first motor 2 and a front second motor 4, as well as a rear first motor 7 and a rear second motor 9, are fixed on the support vibration table 1, all sharing a common centerline. The centerlines of the front first motor 2 and the rear first motor 7 are parallel. The front first motor 2 and the front second motor 4 are arranged in a left-right mirror symmetry, and the rear first motor 7 and the rear second motor 9 are also arranged in a left-right mirror symmetry. The front first motor 2, the front second motor 4, the rear first motor 7, and the rear second motor 9 are four drive motors of the same model. In terms of electrical control, the speed of the four drive motors is set to the same speed. The front first motor 2 and the front second motor 4 rotate in the same direction, and the rear first motor 7 and the rear second motor 9 rotate in the same direction. However, the rotation directions of the front first motor 2 and the rear first motor 7 are opposite.

[0023] Eccentric vibrating blocks 5 are mounted on the rotating shafts of the front first motor 2, the front second motor 4, the rear first motor 7, and the rear second motor 9. When each drive motor rotates, each eccentric vibrating block 5 rotates, producing a vibration effect. In this embodiment, the front first motor 2, the front second motor 4, the rear first motor 7, and the rear second motor 9 are all dual-head motors, with eccentric vibrating blocks 5 mounted at both ends of their rotating shafts. In terms of rotation direction, each eccentric vibrating block 5 rotates inwards, i.e. Figure 1 When viewed from right to left, the eccentric blocks 5 of the front first motor 2 and the front second motor 4 rotate counterclockwise, while the eccentric blocks 5 of the rear first motor 7 and the rear second motor 9 rotate clockwise.

[0024] A front synchronous gear 3, which connects the two shafts, is installed between the inner ends of the shafts of the first front motor 2 and the second front motor 4. A rear synchronous gear 8, which connects the two shafts, is installed between the inner ends of the shafts of the first rear motor 7 and the second rear motor 9. A linkage assembly 6 is provided between the front synchronous gear 3 and the rear synchronous gear 8. The linkage assembly 6 is detachably connected to the support vibration table 1. Under the action of the linkage assembly 6, the front synchronous gear 3 and the rear synchronous gear 8 rotate in opposite directions but maintain the same speed.

[0025] The purpose of setting up the linkage component 6, the front synchronous gear 3, and the rear synchronous gear 8 is to force the two sets of drive motors and their eccentric vibrating blocks 5 to rotate synchronously, thus avoiding the problem of weakened vibration effect caused by asynchronous rotation. The principle is explained as follows: Although the front first motor 2, the front second motor 4, the rear first motor 7, and the rear second motor 9 are all selected as drive motors of the same model, there will still be some differences in the speed parameters of different motors. This difference in speed will gradually cause the eccentric vibrating blocks 5 to become out of sync, resulting in weakened vibration. This problem is solved by using the linkage component 6, the front synchronous gear 3, and the rear synchronous gear 8 to force each eccentric vibrating block 5 to rotate synchronously.

[0026] In this embodiment, keyways are provided in the shaft holes of both the front synchronous gear 3 and the rear synchronous gear 8. The rotating shafts of the front first motor 2 and the front second motor 4 are keyed to the front synchronous gear 3, and the rotating shafts of the rear first motor 7 and the rear second motor 9 are keyed to the rear synchronous gear 8. Therefore, the front synchronous gear 3 can force the front first motor 2 and the front second motor 4 to run synchronously, and the rear synchronous gear 8 can force the rear first motor 7 and the rear second motor 9 to run synchronously.

[0027] Please see Figure 3 It can be seen that:

[0028] The linkage assembly 6 includes a base, on which a detachable and meshing first linkage gear 6-2 and a second linkage gear 6-4 are mounted. The first linkage gear 6-2 meshes with the front synchronous gear 3, and the second linkage gear 6-4 meshes with the rear synchronous gear 8.

[0029] In this embodiment, the base of the linkage assembly 6 includes a top plate 6-6 with a window 6-7 in the middle. Two opposing side plates 6-8 are located at the bottom of the top plate 6-6. The first linkage gear 6-2 and the second linkage gear 6-4 are located between the two side plates 6-8. The shaft end of the first linkage gear 6-2 is mounted on the side plate 6-8 using a first bearing 6-1, and the shaft end of the second linkage gear 6-4 is mounted on the side plate using a second bearing 6-3. The window 6-7 allows observation of the wear condition of the first linkage gear 6-2 and the second linkage gear 6-4 from above, enabling replacement and maintenance when excessive wear occurs. The replacement and maintenance operation involves: removing the entire linkage assembly 6 from the support vibration table 1, removing the first bearing 6-1 and the second bearing 6-3, pulling off the shafts of both linkage gears, and then removing the first linkage gear 6-2 and the second linkage gear 6-4 from between the two side plates 6-8. Afterwards, two new linkage gears are replaced, and the linkage assembly 6 is reinstalled onto the support vibration table 1.

[0030] In this embodiment, the top plate 6-6 of the linkage assembly 6 is provided with three sets of mounting holes (front, middle, and rear), and each set of mounting holes is provided with an assembly screw 6-5. The corresponding positions on the supporting vibration table 1 are provided with three sets of threaded holes (front, middle, and rear), and the lower end of the assembly screw 6-5 is located within the threaded hole. During maintenance, the connection between the linkage assembly 6 and the supporting vibration table 1 can be disconnected by removing the three sets of assembly screws 6-5. During reinstallation, the linkage assembly 6 is installed back to its original position using the three sets of assembly screws 6-5. At this time, the first linkage gear 6-2 establishes a meshing connection with the front synchronous gear 3, and the second linkage gear 6-2 establishes a meshing connection with the rear synchronous gear 8.

[0031] In this embodiment, the first linkage gear 6-2 and the second linkage gear 6-4 of the linkage assembly 6 are wearable nylon gears. Nylon gears are gears made of nylon material. Nylon gears possess excellent comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance, and self-lubricating properties. They also have a low coefficient of friction, some flame retardancy, are easy to process, and are suitable for reinforcement with glass fiber and other fillers to improve rigidity, enhance performance, and expand application range. Of course, the first linkage gear 6-2 and the second linkage gear 6-4 of the linkage assembly 6 can also be selected as metal gears.

[0032] The effect of using nylon gears is that the front synchronous gear 3 and the rear synchronous gear 8 are metal gears. During the linkage transmission process, the metal gears cause wear on the nylon gears. This is a measure to improve operational reliability through active wear. At this time, only the nylon gears are worn while the metal gears on both sides are not worn. When the first linkage gear 6-2 and the second linkage gear 6-4 of the linkage assembly 6 are worn to a certain extent by friction, the aforementioned disassembly and maintenance work is performed.

[0033] Application method:

[0034] Figure 1 The diagram shown is a top view of the structure of the electric vibration device when it is in use. The supporting vibration table 1 is fixedly connected to the main body of the block molding machine, and four drive motors are used to provide the vibration effect. If the block molding machine is a small machine and the vibration intensity requirement is reduced, the linkage component 6 and the two drive motors on one side can be removed, while the two drive motors on the other side, their eccentric vibration block 5 and synchronous gear are retained. In this case, two drive motors are used to provide the vibration effect.
