Abstract
Description
Technical Field
[0001] The utility model relates to a screening machine, in particular to an anti-vibration system for a vibrating powder screening machine. Background Art
[0002] When processing powder materials (such as flour or corn starch powder, etc.), screening is required and then the materials are conveyed to the equipment of the next process through a conveying mechanism. Generally, an electric screening machine is used for screening. The electric screening machine mainly screens the above-mentioned powder materials by vibrating the screen mesh. Since the vibration of the screen mesh is relatively large, how to reduce the vibration of the screen equipment has become a technical problem.
[0003] In the field of mechanical design, vibration reduction generally uses springs. However, the equipment in this application will generate dust during operation, and the spring is made of metal, which may collide with itself during the compression process and cause sparks, posing a safety hazard. Therefore, the applicant of this application has designed a safe vibration reduction system without using springs to meet the production requirements. Content of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the utility model provides an anti-vibration system for a vibrating powder screening machine.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] The anti-vibration system for a vibrating powder screening machine includes a machine base and a screen assembly. A feeding mechanism is provided on the machine base. It is characterized in that: the screen assembly is connected to the machine base through a rubber spring, and the screen assembly is connected to the feeding mechanism through a hose.
[0007] A support is provided on the machine base. The screen assembly includes a support plate. The plastic spring is located between the support and the support plate and is fixed to the support and the support plate by screws.
[0008] The rubber spring is provided with an inner hole. Connectors are provided at both ends of the inner hole. Connecting through holes are provided on the support and the support plate. Connecting screw holes are provided on the connectors. Connecting screws are connected to the connecting screw holes through the connecting through holes.
[0009] The screen assembly includes a screen, an upper screen cylinder, a lower funnel and a clamp assembly. The screen is fixed between the upper screen cylinder and the lower funnel. The upper screen cylinder and the lower funnel are clamped into one body through the clamp assembly. The upper screen cylinder is connected to the machine base through an annular soft edge. The lower funnel is connected to the feeding mechanism through a hose. The support plate is fixed to the upper screen cylinder.
[0010] The bottom edge of the upper sieve cylinder is provided with an upper connecting edge, the mouth edge of the lower funnel is provided with a lower connecting edge, the clamp assembly includes a semi-hoop ring one and a semi-hoop ring two with arc-shaped cross-sections, the upper connecting edge and the lower connecting edge are both clamped in the semi-hoop ring one and the semi-hoop ring two, and the semi-hoop ring one and the semi-hoop ring two are locked by screws, and the edge of the screen is clamped by the upper connecting edge and the lower connecting edge.
[0011] The annular soft edge is pressed tightly on the support plate by an annular pressing strip.
[0012] The beneficial effects of the present utility model are as follows: The screen assembly of the present utility model is installed on the machine base as a whole module through rubber springs. The rubber springs are made of rubber materials, which not only have good shock absorption performance, but also do not generate sparks during the compression process, thus eliminating potential safety hazards and ensuring production safety. Moreover, the screen assembly and the feeding mechanism are connected by a hose. The hose is not easy to transmit vibration and does not generate sparks, thereby also ensuring production safety.

[0026] Refer to Figures 1 to 4, the present utility model discloses an anti-vibration system for a powder vibrating screening machine, which includes a machine base 1 and a screen assembly. A feeding mechanism 2 is provided on the machine base 1. The screen assembly is connected to the machine base 1 through a rubber spring 3, and the screen assembly is connected to the feeding mechanism 2 through a hose 4. The screen assembly of this application is a modular integrated part, so it can be installed on the machine base 1 only by the support of the rubber spring 3. The screen assembly can vibrate to screen out the powder that meets the rules from the mesh holes, and slide into the feeding mechanism 2 by gravity through the hose 4, and then be conveyed to the equipment of the next process through the feeding mechanism 2. In the above structure, the screen assembly is connected to the machine base 1 by the rubber spring 3 and to the feeding mechanism 2 by the hose 4. Therefore, the vibration of the screen assembly is not easily transmitted to the machine base 1 and the feeding mechanism 2, and the risk of generating sparks is avoided.
[0027] As shown in the figure, a support 5 is provided on the machine base 1. The screen assembly includes a support plate 6. The plastic spring is located between the support 5 and the support plate 6 and is fixed to the support 5 and the support plate 6 by screws. The support 5 is a metal plate with rib plates, welded to the support column of the machine base 1, and the support plate 6 is a metal plate for supporting the entire screen assembly. As a further structure, the rubber spring 3 is provided with an inner hole 7, and connectors 8 are provided at both ends of the inner hole 7. Connecting through holes are provided on the support 5 and the support plate 6, and connecting screw holes are provided on the connectors 8. Connecting screws are connected through the connecting through holes and the connecting screw holes. Because rubber is relatively soft, it cannot be well connected to the screws. Therefore, we tightly fit the connectors 8 in the inner hole 7. The connectors 8 are metal columns, and the reliable connection between the support 5 and the support plate 6 and the rubber spring 3 can be achieved through the metal columns.
[0028] As shown in the figure, the screen assembly includes a screen 9, an upper screen cylinder 10, a lower funnel 11 and a clamp assembly. A metal mesh frame 12 is provided around the screen 9. A mesh groove is provided on the mesh frame 12. The edge of the screen 9 is located in the mesh groove and fixed by screws. The screen 9 is fixed between the upper screen cylinder 10 and the lower funnel 11, and the upper screen cylinder 10 and the lower funnel 11 are clamped into one body by a clamp assembly 13. The upper screen cylinder 10 is connected to the machine base 1 through an annular soft edge. Because a feeding port 14 is provided on the machine base 1, and directly below the feeding port 14 are the upper screen cylinder 10 and the screen 9. Therefore, in order to prevent the powder from escaping from the gap between the feeding port 14 and the upper screen cylinder 10, we set an annular soft edge 15 between the feeding port 14 and the upper screen cylinder 10 as a seal. Moreover, the annular soft edge 15 is also a flexible connection. The vibration of the screen 9 assembly is not easily transmitted to the machine base 1 through the annular soft edge 15, and the annular soft edge 15 is made of plastic. The annular soft edge 15 is bent and pressed tightly on the support plate 6 and the flange edge of the feeding port 14 through an annular pressing strip.
[0029] As shown in the figure, specifically, the screen mesh 9 assembly is connected to the hose 4 through the lower funnel 11, and the support plate 6 is fixed on the upper screen cylinder 10. The support plate 6 is square with a hole in the middle. The upper screen cylinder 10 is located in the hole, and the two are fixed by welding. As a further specific structure, the bottom edge of the upper screen drum 10 is provided with an upper connecting rib 16, and the mouth edge of the lower funnel 11 is provided with a lower connecting rib 17. The clamp assembly includes a half hoop ring 1 and a half hoop ring 2 with arc-shaped cross sections. The upper connecting rib 16 and the lower connecting rib 17 are both stuck in the half hoop ring 1 and the half hoop ring 2. Of course, the ends of the half hoop ring 1 and the half hoop ring 2 are provided with end plates with holes, and the half hoop ring 1 and the half hoop ring 2 are locked by screws passing through the end plates with holes and cooperating with nuts. Because the screen 9 needs to be cleaned and maintained, the above structure is also convenient for replacing the screen 9. When replacing, the screen 9 can be pulled out from the gap between the upper connecting rib 16 and the lower connecting rib 17 by loosening the half hoop ring 1 and the half hoop ring 2. After being loaded from the gap, the mesh frame 12 at the edge of the screen 9 is clamped by the upper connecting rib 16 and the lower connecting rib 17 as well as the half hoop ring 1 and the half hoop ring 2.
[0030] The above is a detailed introduction to the anti-vibration system of a powder vibration screening machine provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for general technical personnel in this field, according to the idea of the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
