Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a negative pressure vacuum feeding integrated machine. Background Technology

[0002] The integrated feeding machine is an automated material conveying equipment used in industrial production. Through its mechanical structure, it achieves precise feeding and efficient transfer of raw materials, significantly improving production line efficiency, reducing manual labor intensity, and offering simple operation and high stability. It plays an important role in industries such as chemical, pharmaceutical, and food processing. With technological advancements, the negative pressure vacuum feeding machine has gradually become a new favorite in the industry. This equipment utilizes the principle of vacuum adsorption to transport materials, ensuring a completely sealed and dust-free process that effectively avoids cross-contamination. It also has long-distance conveying capabilities and is particularly suitable for handling dusty materials such as powders and granules. Its energy-saving and environmentally friendly characteristics further broaden its application scope.

[0003] Traditional vacuum feeding machines use a vacuum pump to create a negative pressure environment in a sealed container. The pressure difference is used to draw powder or granular materials from the inlet into the conveying pipe. After the material is conveyed through the pipe to the separation device, the filtration system separates the material from the air, completing the directional conveying. Its operation relies on a stable vacuum degree and gas-solid separation efficiency. However, in actual use, dynamic leakage of the sealing system of the above-mentioned device causes fluctuations in vacuum degree, excessive pressure loss of the filtration unit causes frequent backflushing, and unreasonable design of the bend pipe structure causes excessive local pressure loss.

[0004] Existing negative pressure vacuum feeding integrated machines optimize fluid dynamics parameters based on traditional principles, adopt modular design to improve sealing reliability, and adjust vacuum pump power through intelligent control system to adapt to different material characteristics. However, in actual use, when conveying viscous materials, the above devices tend to have materials that easily adhere to the inner wall of the equipment. The continuous accumulation of residues will reduce the effective conveying volume, increase cleaning difficulty and downtime maintenance frequency, and affect the stability of continuous production. Therefore, a negative pressure vacuum feeding integrated machine is proposed to solve the above problems. Utility Model Content

An electrical box 19 is fixedly connected to the front of the outer wall of the storage hopper 1. A solenoid valve 20 is also fixedly connected to the front of the outer wall of the storage hopper 1. A bracket 21 is fixedly connected to the left side of the outer wall of the storage hopper 1, and the bracket 21 is used to house the controller 22. The controller 22 is fixedly connected to the top of the outer wall of the bracket 21, and controls the start and stop of the device. A pulse assembly is located on the left side of the storage hopper 1. The pulse assembly includes a pressurized air tank 14. The right side of the outer wall of the pressurized air tank 14 is fixedly connected to the left side of the outer wall of the storage hopper 1. A pulse valve 13 is fixedly connected to the top of the outer wall of the pressurized air tank 14. The top of the outer wall of the storage tank 13 is connected to a pulse air pipe 12, one end of which is connected to a motor unit 9. A flexible flow guide mechanism 2 is provided on the right side of the outer wall of the storage tank 1. The flexible flow guide mechanism 2 is used to prevent brittle materials from being damaged during vacuum suction. The pressurized air tank 14 is connected to the pulse air pipe 12 through the pulse valve 13 to provide pressurized compressed air to the system, drive pulse jet to efficiently remove dust accumulated in the storage hopper, and ensure the smooth operation of the filtration system and the continuous and stable operation of the equipment. The electrical box 19 is the core control unit. The electrical box 19 and the electrical system coordinate the opening and closing frequency of the pulse valve 13 and the pressure parameters of the pressurized air tank 14 to precisely control the suction and conveying process.

[0033] Specifically, the storage hopper 1 serves as the core device for material storage and conveying. It receives powder particles conveyed under vacuum through a suction port. The motor unit 9 acts as the power hub, driving a vacuum pump to create a negative pressure system. A rotating shaft 15 extends from the bottom of its outer wall. This shaft 15 connects to the drive mechanism and drives the bottom cleaning assembly. A fixing button 16 is fitted at the end of the shaft 15 to enhance rotational stability. Two connecting rods 3 are symmetrically arranged in the lower middle part of the shaft 15, serving as load-bearing supports for the cleaning assembly. The ends of the connecting rods 3 are respectively connected to U-shaped connecting crossbars 4. Brush seats 5 are installed on the outer walls of both sides of the connecting crossbars 4. A fan 6 and fixing bolts 7 are equipped on the surface of the brush seats 5. Symmetrically distributed silicone bristles 8 are fixed to the outside of the brush seats 5. After the silicone bristles 8 remove sticky substances, the fan 6 performs a blowing operation. The right side of the material hopper 1 is equipped with an L-shaped tube 23 and a conical suction nozzle 24, which work together to complete the material suction action. The front of the equipment is equipped with an electrical box 19 and a solenoid valve 20.

The pulse air pipe 12 is connected to the motor unit 9 to form a compressed air circuit. The flexible flow guiding mechanism 2 is installed on the right side of the material hopper 1 to prevent brittle materials from being damaged during transport.

The electrical box 19 integrates the control module and electrical system to precisely coordinate the opening and closing sequence of the pulse valve 13 and the pressure value of the pressurized air tank 14, so as to realize the intelligent control of the material conveying process.

[0034] Reference Figure 1 and Figure 5 The flexible flow guiding mechanism 2 includes a wear-resistant layer 201, which is made of high-hardness wear-resistant composite material to reduce the impact wear caused by high-speed material flow, significantly extending the service life of the suction port and ensuring stable and efficient material conveying performance under high-frequency suction operation. The outer wall of the wear-resistant layer 201 is fixedly connected to the inner wall of the L-shaped tube 23. A silicone layer 202 is fixedly connected to the inner wall of the wear-resistant layer 201. The silicone layer 202 plays a certain buffering role for brittle materials. A support ring 203 is fixedly connected to the inner wall of the conical suction nozzle 24. The support ring 203 is used to support the tube wall. Multiple springs 204 are fixedly connected to the inner wall of the support ring 203. The springs 204 can be elastically deformed to reduce rigid collisions. A buffer plate 205 is fixedly connected to the far end of the multiple springs 204, which absorbs the frictional energy between the material and the suction port.

[0035] Specifically, the flexible flow guiding mechanism 2 consists of multiple components to achieve efficient material transfer. Its core component is the wear-resistant layer 201, made of high-hardness composite material. By reducing the impact and wear effect of high-speed flowing materials on the pipe wall, it effectively extends the service life of key parts of the suction port, ensuring stable material conveying efficiency even in high-frequency continuous operation scenarios. The outer structure of the wear-resistant layer 201 is physically connected to the inner wall of the L-shaped pipe 23, and its inner surface is tightly fitted with a silicone layer 202. This silicone material provides flexible buffer protection for brittle materials, preventing material from being damaged. Material breakage affects the quality of transmission. A support ring 203 is provided in the inner cavity of the conical suction nozzle 24. This ring structure mainly undertakes the function of supporting the pipe shape and ensuring the structural stability of the pipe body under negative pressure. Several springs 204 are evenly distributed on the inner side of the support ring 203. These elastic elements can buffer external impact forces through their own deformation characteristics, significantly reducing rigid contact damage generated during material transmission. The ends of all springs 204 are connected to a buffer plate 205. This component further optimizes the protection performance of the equipment for materials by absorbing the frictional kinetic energy generated when the material comes into contact with the suction nozzle.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A handle 10 is fixedly connected to the top of the outer wall of the motor unit 9. The handle has an ergonomic arc structure design, which makes it easy to grip the mobile device with one hand and realize the need for quick transfer of workstations in industrial scenarios. A silicone pad 11 is fixedly connected to the outer wall of the handle 10. The handle has a high coefficient of friction surface and an elastic buffer structure to effectively prevent hand slippage during handling. Multiple locking lugs 17 are fixedly connected to the outer wall of the motor unit 9. Each locking lug 17 has a locking buckle 18 fixedly connected to its outer wall. The locking lugs 17 and locking buckles 18 cooperate to connect the motor unit 9 to the storage bin 1. The outer walls of the multiple locking buckles 18 are fixedly connected to the outer wall of the storage bin 1. A viewing window 26 is fixedly connected to the rear side of the outer wall of the storage bin 1. The viewing window 26 is used to observe the material status. Reinforcing plates 25 are fixedly connected to the four corners of the outer wall of the storage bin 1. The reinforcing plates 25 are used to reinforce the bottom.

[0037] Specifically, the top of the outer wall of the motor unit 9 is equipped with a handle 10. The handle 10 adopts an ergonomic arc-shaped structure design, which can be adapted to single-handed gripping action and meet the operational needs of rapid equipment transfer in industrial scenarios. The surface of the handle 10 is covered with a silicone pad 11. The silicone pad 11 combines the dual characteristics of a high-friction coefficient surface layer and an elastic buffer layer, providing a stable grip and reducing the risk of hand slippage during handling. Several locking lugs 17 are distributed on the outer wall of the motor unit 9. Each locking lug 17 is equipped with a latch 18. The linkage structure between the locking lugs 17 and the latch 18 realizes a stable connection between the motor unit 9 and the storage bin 1. The outer wall of the storage bin 1 has corresponding fixing points that match the latch 18. A viewing window 26 is installed on the rear outer wall of the storage bin 1. This transparent observation port facilitates real-time monitoring of the material status inside the storage bin 1. Reinforcing plates 25 are welded at the four corners of the outer wall of the storage bin 1. These metal reinforcements improve the overall load-bearing capacity and structural stability of the bottom of the storage bin 1 through a triangular support structure.

[0038] Working principle: First, the drive motor 9 is mechanically connected to the extended rotating shaft 15. Multiple sets of fixing devices are used on the surface of the rotating shaft 15 to securely assemble the brush holder 5. Several neatly arranged silicone bristle 8 components are distributed on the outer edge of the brush holder 5. The core area integrates a centrifugal fan 6 device. When the motor 9 is powered on, the rotating shaft 15 drives the brush holder 5 to move synchronously. Under the action of centrifugal force, the silicone bristles 8 maintain dynamic contact with the inner wall of the storage tank 1. At the same time, the fan 6 device generates a high-speed airflow shock wave. The two forces form an alternating cleaning mode on the inner wall of the container. The pulsed airflow combined with physical scrubbing produces a synergistic effect, so that the residual material layer attached to the inner wall is peeled off layer by layer. This design effectively improves the efficiency and coverage of the cleaning operation of the inner wall of the storage container through the combined linkage of the moving components and the airflow generating device, and finally realizes an intelligent cleaning operation process without manual intervention.

[0039] Furthermore, a conical guide structure is integrated at the feed port of the material conveying system. The inner cavity of the guide structure is equipped with multiple sets of spring 204 structures and buffer plate 205 structures. The surface of the L-shaped pipe 23 at the top of the structure is coated with a multi-layer functional protective coating. The high-density ceramic wear-resistant layer 201 significantly enhances the wear resistance of the pipe. The elastic silicone layer 202 can adjust the airflow force under negative pressure environment. Through elastic deformation and pressure buffering mechanism, the risk of rigid contact is offset, ensuring that brittle material particles maintain physical stability during the conveying process. This composite protection system takes into account both equipment durability and material preservation, providing reliable technical support for vacuum suction operations of powder and crystalline fragile materials.
