Description

Technical Field

[0001] This utility model relates to the technical field of glass substrate production equipment, and in particular to a segmented material silo structure for substrate glass dispensing. Background Technology

[0002] In the glass substrate production process, commonly used silos often adopt an integrated conical structure, relying on the material's own weight for feeding. While this type of silo can meet basic requirements when handling raw materials with good flowability and low adhesion, it has significant shortcomings when handling fine powders, easily hygroscopic materials, or materials prone to clumping. On the one hand, materials tend to accumulate and adhere to the silo walls and conical part, forming "bridging" or blockages, leading to feeding interruptions or uneven feeding. On the other hand, traditional silos lack effective auxiliary feeding mechanisms, often relying on manual tapping or airflow to clear blockages, which is not only inefficient but also poses safety hazards and can easily damage the silo structure. In addition, integrated silos also have limitations in terms of sealing, and dust can easily escape during the feeding process, polluting the environment and affecting cleanroom requirements.

[0003] Therefore, there is an urgent need for a segmented silo device with a reasonable structure, reliable operation, and suitable for adding fine raw materials, so as to ensure the accuracy of glass substrate batching and the continuity of the production process. Utility Model Content

[0006] Furthermore, both ends of the first connecting part are provided with flange connecting pieces. The flange connecting piece at the top is fastened and sealed to the bottom of the vertical compartment section by a first bolt assembly, and the flange connecting piece at the bottom is fastened and sealed to the top of the conical compartment section by a second bolt assembly.

[0007] Furthermore, the top of the second connecting part is fastened and sealed to the bottom of the conical bin section by the first clamp; the bottom of the second connecting part is fastened and sealed to the feed end of the screw conveyor by the second clamp.

[0008] Furthermore, the first connecting part and the second connecting part together constitute a vibration isolation system, so that the vibration of the conical bin section is isolated from the vertical bin section and the screw conveyor.

[0009] Furthermore, the spring assembly includes a bolt rod, a spring sleeved on the bolt rod, and a nut; both ends of the bolt rod pass through connecting lugs respectively provided on the vertical compartment section and the conical compartment section, and are locked by the nut so that the conical compartment section is elastically suspended below the vertical compartment section.

The structure is characterized by including a vertical hopper section 1, a first connecting part 2, a conical hopper section 4, and a second connecting part 6 arranged sequentially from top to bottom. The vertical compartment 1 has a vertically arranged cylindrical structure; The conical hopper section 4 has a cone-shaped structure that is larger at the top and smaller at the bottom, and a vibration motor 5 is installed on its outer wall. The first connecting part 2 is made of rubber, and its upper and lower ends are respectively sealed to the bottom outlet of the vertical compartment 1 and the top inlet of the conical compartment 4; The second connecting part 6 is made of rubber, and its upper and lower ends are respectively sealed and connected to the bottom outlet of the conical bin section 4 and the feed end of the screw conveyor 7. Multiple spring assemblies 3 are connected between the vertical compartment section 1 and the conical compartment section 4. The multiple spring assemblies 3 are arranged in a circumferential array about the axis of the vertical compartment section 1, and the conical compartment section 4 is suspended below the vertical compartment section 1 by the spring assemblies 3.

[0017] Both ends of the first connecting part 2 are provided with flange connecting pieces 201. The flange connecting piece 201 at the top is fastened and sealed to the bottom of the vertical compartment section 1 by a first bolt assembly, and the flange connecting piece 201 at the bottom is fastened and sealed to the top of the conical compartment section 4 by a second bolt assembly.

[0018] The spring assembly 3 includes a bolt rod 301, a spring 302 sleeved on the bolt rod 301, and a nut 303; the two ends of the bolt rod 301 pass through connecting lugs provided on the vertical compartment section 1 and the conical compartment section 4 respectively, and are locked by the nut 303 so that the conical compartment section 4 is elastically suspended below the vertical compartment section 1.

[0019] The feed end of the screw conveyor 7 is connected to the feed end of the screw conveyor 7. It includes a vertical section 1, a first connecting part 2, a conical section 4, and a second connecting part 6 arranged sequentially from top to bottom. The vertical section 1 is a vertically arranged cylindrical structure with a feed port 101 at the top. Its inner diameter is designed according to the raw material storage capacity, and its inner wall is polished to reduce material adhesion. It is mainly used to store raw materials to be added. The raw materials are conveyed by the screw conveyor 7 and discharged from the discharge end 701. The first connecting part 2 is made of wear-resistant and highly elastic rubber. Its upper and lower ends are respectively sealed to the bottom outlet of the vertical section 1 and the top inlet of the conical section 4, serving both sealing and vibration functions. Dynamic buffer function; the conical hopper section 4 has a cone-shaped structure that is larger at the top and smaller at the bottom, with polished inner walls and a vibration motor 5 installed on the outer wall (which breaks up the material "bridging" through vibration). It is elastically suspended below the vertical hopper section 1 by the spring assembly 3; the second connecting part 6 is also made of rubber, with its upper and lower ends respectively sealingly connected to the bottom outlet of the conical hopper section 4 and the feed end of the screw conveyor 7, further enhancing the sealing and vibration isolation effect; the spring assembly 3 is arranged in a circumferential array about the axis of the vertical hopper section 1 (preferably 4-6), with one end connected to the vertical hopper section 1 and the other end connected to the conical hopper section 4, providing stable support for the conical hopper section 4 without hindering the transmission of vibration.

[0020] The first connecting part 2 has two integrally formed metal flange connecting pieces 201 at both the top and bottom. The top flange connecting piece 201 is attached to the bottom end face of the vertical compartment section 1 and is fastened and sealed by the first bolt assembly (including bolts, nuts and elastic washers). The bottom flange connecting piece 201 is attached to the top end face of the conical compartment section 4 and is fastened and sealed by the second bolt assembly. The combination of flange and elastic washer can effectively eliminate connection gaps and prevent dust from escaping. At the same time, the bolt connection facilitates subsequent disassembly and maintenance. The spring assembly 3 includes a bolt rod 301, a compression spring and two locking nuts 303. The lower outer wall of the vertical compartment section 1 and the upper outer wall of the conical compartment section 4 are welded with metal connecting lugs. The bolt rod 301 passes through the two sets of lugs in sequence and is fixed at both ends by locking nuts 303. The compression spring is sleeved on the bolt rod 301 and located between the two sets of lugs to realize the elastic suspension of the conical compartment section 4.

[0021] The flange connection improves the sealing and structural stability of the first connection part 2, the standard spring assembly 3 ensures reliable support for the conical bin section 4, can effectively assist material feeding during vibration, and significantly reduces the energy transmitted from vibration to the vertical bin section 1.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the top of the second connecting part 6 is fastened and sealed to the bottom of the conical bin section 4 by the first clamp 8; the bottom of the second connecting part 6 is fastened and sealed to the feed end of the screw conveyor 7 by the second clamp 9.

[0023] The spring 302 is a compression spring, which is in a pre-compressed state on the bolt rod 301.

[0024] In this embodiment, the ease of maintenance of the second connecting part 6 and the supporting performance of the spring assembly 3 are optimized: The clamp connection of the second connecting part 6: the top is fitted on the outside of the bottom outlet of the conical bin section 4 and is fastened and sealed by the first clamp 8; the bottom is fitted on the outside of the feed end of the screw conveyor 7 and is fastened and sealed by the second clamp 9; the clamp connection does not require the removal of bolts, and the second connecting part 6 can be quickly disassembled and assembled, which is convenient for cleaning and maintenance.

[0025] Pre-compression design of spring assembly 3: The compression spring in spring assembly 3 is in a pre-compression state after installation; the pre-compression state can provide continuous and stable support force, avoid excessive stretching of the rubber connection part due to the sag of the conical chamber section 4 due to its own weight, and at the same time buffer the vibration impact force, so that the vibration of the conical chamber section 4 is more stable.

[0026] The clamp connection reduces maintenance difficulty, and the pre-compression spring 302 extends the life of the rubber connection part, while improving the stability of vibration and reducing equipment operating noise.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the first connecting part 2 and the second connecting part 6 together constitute a vibration isolation system, so that the vibration of the conical bin section 4 is isolated from the vertical bin section 1 and the screw conveyor 7.

[0028] The vibration motor 5 is installed in the upper middle part of the outer wall of the conical compartment section 4.

[0029] In this embodiment, the focus is on enhancing vibration isolation and anti-clogging efficiency, as detailed below: Construction of the vibration isolation system: Both the first connecting part 2 and the second connecting part 6 are made of high-elasticity neoprene rubber (with excellent damping performance). When the vibration motor 5 is working, the first connecting part 2 absorbs vibration energy through elastic deformation, preventing vibration from being transmitted to the vertical bin section 1 (avoiding uneven accumulation of raw materials in the vertical bin section 1); the second connecting part 6 similarly absorbs vibration energy, preventing vibration from being transmitted to the screw conveyor 7 (avoiding wear on conveyor components). Together with the spring assembly 3, they form a complete vibration isolation system.

[0030] Installation position of vibration motor 5: Vibration motor 5 is fixed to the upper middle part of the outer wall of the conical silo section 4 by a bracket; this position can make the vibration evenly transmitted to the entire inner wall of the conical silo section 4, avoiding insufficient vibration at the top due to installation at the bottom (which still makes it easy to accumulate) or excessive vibration transmission due to installation at the top (which affects the isolation effect), and maximizing the elimination of material bridging and accumulation.

[0031] The vibration isolation system protects the vertical compartment 1 and the screw conveyor 7. The optimized motor position improves the anti-clogging effect and further ensures the continuity of material feeding.
