Description

Technical Field

[0001] This utility model relates to the technical field of shock absorption and buffer devices, specifically a shock absorption and buffer device for the vibration table of a cement block molding machine. Background Technology

[0002] The vibrating table of a cement block molding machine is a core component of cement block production. Its function is to eliminate gaps between particles through vibration, improve the compressive strength and durability of the blocks, reduce internal porosity, prevent blocks from cracking or having uneven strength, shorten molding time, and ensure stable quality of batch products. It is usually composed of a vibrating motor and a steel platform. In order to reduce the impact on the frame and prevent equipment damage caused by resonance, the vibrating table needs to be equipped with a shock-absorbing buffer device.

[0003] In existing technologies, during the production of cement blocks, workers pour the proportioned concrete into a molding mold, level the top of the mold, and then let it stand for 10 minutes to allow it to set and be demolded. During this process, air bubbles in the concrete need to be removed. Manual labor or simple pressing is insufficient to remove most of these air bubbles, resulting in numerous internal pores in the final blocks. Against this backdrop, the aforementioned vibrating table can replace manual labor and remove gaps and air bubbles between concrete particles. In actual use, workers do not need to fix the mold; they only rely on baffles around the vibrating table to prevent the mold from falling.

[0004] Currently, vibration tables typically use mechanical springs for shock absorption, utilizing the elastic deformation of helical springs to absorb vibration energy. These springs are usually installed between the vibration table and the equipment base, buffering vibration through compression and rebound. However, mechanical spring shock absorption only provides vertical buffering and has poor lateral stability, leading to horizontal swaying of the vibration table. This results in relative displacement between the mold and the vibration table surface, causing deviations in block dimensions (especially in hollow blocks, leading to uneven wall thickness due to hole misalignment), and increasing the scrap rate of cement blocks. Therefore, it is necessary to develop a vibration damping device for cement block molding machines to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration damping and buffering device for a cement block molding machine vibration table to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping and buffering device for a cement block forming machine vibration table, comprising a steel platform, a vibration table surface fixedly installed on the top of the steel platform, a vibration motor fixedly installed on the bottom of the steel platform, and a cross-sloping vibration damping and buffering mechanism and a lateral limiting mechanism provided at the bottom of the steel platform.

[0007] Preferably, the cross-sloping shock absorption and buffer mechanism includes a spring plug head one, which is fixedly installed at the bottom of the steel platform. A helical spring is provided on the outside of the spring plug head one, and a spring plug head two is provided at the end of the helical spring away from the spring plug head one. A base is fixedly installed at the bottom of the spring plug head two, and a support block is fixedly installed at the bottom of the base.

[0008] Preferably, four helical springs are provided, and the four helical springs are arranged symmetrically at an angle of °, and the center of symmetry of the four helical springs coincides with the center of mass of the steel platform.

[0009] Preferably, the first spring plug and the second spring plug are interference-fitted with the end coil of the helical spring, and the interference amount is 0.3-0.5mm.

[0010] Preferably, the lateral limiting mechanism includes a fixing block, which is fixedly installed on the bottom of the vibration table surface. A limiting slide rod is fixedly installed on the outer side of the fixing block, and a limiting stop block is fixedly installed on the outer side of the limiting slide rod. A sliding groove strip is fixedly installed on the outer side of the base.

[0011] Preferably, there are two sets of lateral limiting mechanisms, and the two sets of lateral limiting mechanisms are symmetrically distributed at the bottom of the steel platform.

[0012] Preferably, a limiting groove is formed inside the slide bar, and the limiting slide rod is slidably installed inside the limiting groove formed inside the slide bar.

[0013] Compared with the prior art, this utility model provides a vibration damping and buffering device for the vibration table of a cement block molding machine, which has the following beneficial effects:

[0014] 1. The vibration damping and buffering device of the cement block molding machine, through the setting of the cross-inclined vibration damping and buffering mechanism, by symmetrically arranging four helical springs at a 75° inclination angle during use, can suppress the lateral displacement of the vibration table surface while retaining the vertical vibration damping and buffering capacity. With the cooperation of the lateral limiting mechanism, the vibration table surface under vibration will only move up and down, which can avoid relative displacement between the mold and the top of the vibration table surface, avoid block size deviation, and reduce the scrap rate of cement blocks.

[0015] 2. The vibration damping and buffering device of the cement block molding machine, through the lateral limiting mechanism, uses the limiting groove opened inside the slide bar to limit the limiting slide rod during use, so that the vibration table surface can only move up and down, further strengthening the limitation of lateral displacement and improving the stability of the vibration damping and buffering device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example:

[0025] Please see Figure 1-3This utility model provides a technical solution: a vibration damping and buffering device for a cement block forming machine vibration table, including a steel platform 1, a vibration table surface 4 fixedly installed on the top of the steel platform 1, a vibration motor 5 fixedly installed on the bottom of the steel platform 1, and a cross-sloping vibration damping and buffering mechanism 2 and a lateral limiting mechanism 3 provided at the bottom of the steel platform 1.

[0026] Furthermore, the cross-sloping shock absorption mechanism 2 includes a spring plug 21, which is fixedly installed at the bottom of the steel platform 1. A helical spring 22 is provided on the outside of the spring plug 21. A spring plug 23 is provided at the end of the helical spring 22 away from the spring plug 21. A base 24 is fixedly installed at the bottom of the spring plug 23. A support block 25 is fixedly installed at the bottom of the base 24. Through the cross-sloping shock absorption mechanism 2, the cross-sloping spring group can ensure vertical shock absorption capacity while preventing lateral instability.

[0027] Furthermore, four helical springs 22 are provided, and the four helical springs 22 are symmetrically arranged at an inclination angle of 75°, and the center of symmetry of the four helical springs 22 coincides with the center of mass of the steel platform 1. The symmetrical distribution of the inclination angle design improves the lateral stability of the helical springs 22.

[0028] Furthermore, the spring plug 1 21 and the spring plug 23 are interference-fitted with the end coil of the helical spring 22, with an interference of 0.3-0.5mm. This facilitates the installation of the helical spring 22 inside the spring plug 1 21 and the spring plug 23, so that the helical spring 22 can stably provide shock absorption and cushioning to the steel platform 1, and at the same time facilitate the installation, removal and replacement of the helical spring 22.

[0029] Please see Figure 4 Furthermore, the lateral limiting mechanism 3 includes a fixed block 31, which is fixedly installed at the bottom of the vibration table surface 4. A limiting slide rod 32 is fixedly installed on the outside of the fixed block 31, and a limiting stop block 33 is fixedly installed on the outside of the limiting slide rod 32. A sliding groove strip 34 is fixedly installed on the outside of the base 24. Through the lateral limiting mechanism 3, the lateral limiting of the vibration table surface 4 is further strengthened, so that the vibration table surface 4 is always in a state of vertical displacement.

[0030] Furthermore, two sets of lateral limiting mechanisms 3 are provided, and the two sets of lateral limiting mechanisms 3 are symmetrically distributed at the bottom of the steel platform 1. The design of the two sets of symmetrically distributed lateral limiting mechanisms 3 improves the stability of the lateral limiting of the vibration table surface 4.

[0031] Furthermore, a limiting groove is provided inside the slide bar 34, and a limiting slide rod 32 is slidably installed inside the limiting groove provided inside the slide bar 34. By using the limiting slide rod 32 that slides up and down inside the limiting groove, the steel platform 1 is limited, so that the vibration table surface 4 can only move up and down.

[0032] In actual operation, when this device is used to prepare cement blocks, the mold is placed on top of the vibrating table 4. The vibrating motor 5 drives the vibrating table 4 to vibrate. The four symmetrically arranged helical springs 22 reduce the horizontal swaying of the vibrating table 4. At the same time, the limiting slide rod 32 slides in the groove inside the slide bar 34. With the limiting slide rod 32 and the limiting block 33, the vibrating table 4 will only move up and down, avoiding horizontal swaying. The mold will not have relative displacement with the vibrating table 4.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
