Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and in particular to a powder box feeding device for a powder press. Background Technology

[0002] In modern industrial production, powder compactors are widely used in powder metallurgy, ceramics manufacturing, pharmaceutical tableting, food processing, and other fields. They produce various products with specific shapes and properties by compacting powdered raw materials. In the powder compactor's workflow, the powder feeding device is a crucial link in material conveying; its performance directly affects the compactor's production efficiency, forming quality, and energy consumption.

[0003] However, most existing technologies employ open-structure powder replenishment. In actual operation, this open design makes the powder highly susceptible to splashing during conveying, pouring, and filling of the powder box due to airflow disturbances and equipment vibrations. This not only wastes materials but also fills the workshop with dust, severely deteriorating the working environment. Furthermore, prolonged exposure to high dust levels can easily lead to respiratory illnesses for operators, harming their health. Simultaneously, the dispersed dust adheres to the precision components of the production equipment, affecting normal operation, increasing maintenance costs and the probability of malfunctions, and shortening the equipment's lifespan. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where open-structure powder replenishment makes the powder easily splashed during the conveying, pouring and filling of powder boxes due to factors such as airflow disturbance and equipment vibration. This not only causes material waste, but also makes the workshop dusty and seriously deteriorates the working environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powder box feeding device for a powder press, comprising: a transmission frame; a conveyor belt disposed between the transmission frames, with a first power component disposed on one side of the conveyor belt, the first power component being fixedly connected to the conveyor belt; a clamping assembly disposed on both sides of the upper end of the conveyor belt; a mounting frame disposed above the conveyor belt, with a storage mechanism fixedly disposed at its upper end; a feeding assembly fixedly disposed below the storage mechanism; and a dust collection assembly disposed on both sides of the feeding assembly.

[0006] The technical advantages of adopting the above-mentioned further solution are: by using a transmission frame and a conveyor belt to transport powder boxes, the clamping components ensure stability, the storage mechanism and the feeding components achieve automatic feeding, and the dust collection components clean up dust, which can efficiently and stably feed materials, ensure a clean environment, and improve feeding efficiency and quality.

[0007] In a preferred embodiment, the feeding assembly includes: a screw conveyor bucket disposed below the storage mechanism; a feeding pipe disposed through one end of the screw conveyor bucket to form a raw material transportation channel; and an electric control valve disposed at the end of the feeding pipe to realize the opening and closing of the feeding pipe.

[0008] The technical advantages of adopting the above-mentioned further solution are as follows: the screw conveyor bucket transports the powder from the storage mechanism to the injection pipe, forming a transport channel. The electric control valve controls the opening and closing of the injection pipe, enabling precise and stable powder delivery, achieving quantitative feeding, avoiding powder leakage and waste, and improving the controllability and efficiency of feeding.

[0009] In a preferred embodiment, the clamping assembly includes: a fixing block, movably disposed on both sides of the upper end of the transmission frame, with a mounting plate movably disposed on its upper end; a stop plate, disposed on one side of the mounting plate; and multiple threaded rods, which are threadedly engaged in the mounting plate, with their other ends connected to one side of the stop plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the clamping component is mounted on the fixed blocks on both sides of the transmission frame. A backing plate is provided on one side of the mounting plate. Multiple sets of threaded rods pass through the mounting plate and are threadedly connected to the backing plate. The position of the backing plate can be adjusted by rotating the threaded rods, thereby firmly clamping powder boxes of different specifications and ensuring that the powder boxes are accurately positioned and do not shake during the transmission process.

[0011] In a preferred embodiment, the storage mechanism includes: a fixed frame, fixedly installed on the upper end of the mounting frame; a storage hopper, disposed on the fixed frame, with a sealing cover covering its upper end; a stirring shaft, disposed inside the storage hopper, with multiple sets of stirring rods welded to its exterior; and a second power component, disposed outside the storage hopper, with its output end connected to the stirring shaft.

[0012] The technical effects of adopting the above-mentioned further solution are as follows: the storage mechanism is installed on the mounting frame through a fixed frame, the storage hopper is equipped with a sealing cover to prevent dust and moisture, the internal stirring shaft drives multiple sets of stirring rods, driven by an external second power component, which can effectively stir the powder to prevent agglomeration, ensure that the powder in the storage hopper is uniform and loose, provide stable raw materials for subsequent feeding, and improve feeding quality and efficiency.

[0013] In a preferred embodiment, the dust collection assembly includes: a suction hood, fixedly disposed on both sides of the injection pipe; a suction wheel, disposed on the suction hood; and a fan, disposed on one side of the suction hood.

[0014] The technical effect of adopting the above-mentioned further solution is that the dust collection component is equipped with suction hoods on both sides of the feeding pipe, with suction wheels installed on the hoods and a fan on one side. When working, the fan drives the suction wheels to form a negative pressure, and the dust raised during the feeding process is adsorbed by the suction hoods. This can effectively purify the working environment, reduce dust pollution, avoid powder waste, and at the same time ensure the cleanliness of the equipment and the health of the operators.

[0015] In a preferred embodiment, a cleaning frame is provided on one side of the transmission frame, a cleaning brush is connected to one end of the cleaning frame, and the other end of the cleaning brush abuts against the surface of the conveyor belt.

[0016] The technical effect of adopting the above-mentioned further solution is that a cleaning frame is set on one side of the transmission frame, and the cleaning brush connected to its end face abuts against the surface of the conveyor belt. It can continuously clean the residual powder on the surface when the conveyor belt is running, prevent the accumulation of powder from affecting the conveying accuracy and equipment operation, keep the conveyor belt clean, avoid powder contamination of subsequent processes, and improve the overall stability and reliability of the device.

[0017] In a preferred embodiment, a limiting guide rail is provided at the upper end of the fixing block, and a locking block that cooperates with it is provided at the bottom of the mounting plate.

[0018] The technical effect of adopting the above-mentioned further solution is that the upper end of the fixed block is provided with a limiting guide rail, and the bottom of the mounting plate is provided with a locking block. The two cooperate with each other to allow the mounting plate to slide smoothly along the guide rail, realize the position adjustment of the clamping component, facilitate the adaptation to powder boxes of different sizes, and at the same time ensure the accurate guidance when the mounting plate moves, thereby enhancing the stability and flexibility of the clamping structure.

[0019] In a preferred embodiment, an activated carbon adsorption element is provided on the side of the air intake hood near the air inlet.

[0020] The technical effect of adopting the above-mentioned further solution is that: an activated carbon adsorption component is set on one side of the air inlet of the suction hood. By utilizing the adsorption characteristics of activated carbon, dust and odors can be further filtered during the dust collection process, improving the air purification effect, reducing the emission of harmful particles, ensuring a clean working environment, preventing dust from escaping and affecting equipment and personnel, and enhancing the purification capacity and practicality of the dust collection components.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. This utility model utilizes a screw conveyor bucket and an electric control valve to work together, enabling continuous and controllable conveying of powder in the storage hopper via the screw conveyor bucket, avoiding the powder scattering caused by traditional open-type dumping methods. The electric control valve can precisely control the opening and closing of the filling pipe according to the position and filling amount of the powder box, reducing the time the powder is exposed to air and minimizing material waste.

[0023] 2. This utility model, by setting suction hoods on both sides of the injection pipe, in conjunction with suction wheels and fans, can capture the overflowing dust in real time during the powder filling process. Activated carbon adsorption components further filter fine particles, and the purified air can be recycled or discharged in compliance with standards. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a powder box feeding device for a powder press, characterized in that it includes:

[0033] A transmission frame 1 has a conveyor belt 2 between its two opposite sides. One side of the conveyor belt 2 is fixedly connected to the output end of the first power component 22. The first power component 22 drives the conveyor belt 2 to rotate cyclically along the length of the transmission frame 1.

[0034] The clamping components are symmetrically arranged on both sides of the upper end of the conveyor belt 2, and are used to laterally position and clamp the powder box placed on the conveyor belt 2.

[0035] Mounting frame 3 is positioned across the top of conveyor belt 2, and a storage mechanism is fixedly mounted on its upper end. The storage mechanism includes a fixed frame 4 fixedly mounted on mounting frame 3, a storage hopper 5 mounted on fixed frame 4, a sealing cover 6 covering the upper end of storage hopper 5, a stirring shaft 10 disposed inside storage hopper 5, and a second power component 7 disposed outside storage hopper 5 with its output end connected to stirring shaft 10. Multiple stirring rods 11 are welded to the outside of stirring shaft 10.

[0036] The feeding assembly is fixedly installed below the storage mechanism, including a screw conveyor 12 connected to the bottom of the storage hopper 5, a feeding pipe 8 through one end of the screw conveyor 12, and an electric control valve 9 installed at the end of the feeding pipe 8. The screw conveyor 12 and the feeding pipe 8 form a raw material transportation channel from the storage hopper 5 to the powder box.

[0037] The dust collection assembly is located on both sides of the feeding assembly. It includes a suction hood 19 fixedly installed on both sides of the feeding pipe 8, a suction wheel 20 installed on the suction hood 19, and a fan 21 installed on one side of the suction hood 19. The suction wheel 20 is connected to the output shaft of the fan 21. An activated carbon adsorption element is provided on the side of the suction hood 19 near the air inlet.

[0038] like Figure 1-5 As shown, the clamping assembly includes fixed blocks 13 movably disposed on both sides of the upper end of the transmission frame 1, a mounting plate 14 movably disposed on the upper end of the fixed blocks 13, a stop plate 17 disposed on one side of the mounting plate 14, and multiple sets of threaded rods 18 that are threadedly engaged in the mounting plate 14. The other end of the threaded rods 18 is rotatably connected to one side of the stop plate 17. A limit guide rail 15 is provided at the upper end of the fixed blocks 13, and a locking block 16 that slides with the limit guide rail 15 is provided at the bottom of the mounting plate 14.

[0039] like Figure 1-5 As shown, a cleaning frame 23 is provided on one side of the transmission frame 1. A cleaning brush 24 is connected to the end face of the cleaning frame 23 through an elastic connector. The bristles of the cleaning brush 24 elastically abut against the surface of the conveyor belt 2 to clean the powder residue on the surface of the conveyor belt 2.

[0040] Working principle: This equipment is a powder box feeding device for a powder press. In use, open the sealing cover 6 of the storage hopper 5, pour the powder into the storage hopper 5, close the sealing cover 6, and start the second power unit 7 to drive the stirring shaft 10 and stirring rod 11 to rotate, preventing powder from clumping. Then, by rotating the threaded rod 18, the threaded engagement pushes the abutment plate 17, adjusting the distance between the two abutment plates 17 to be slightly greater than the width of the powder box.

[0041] The first power unit 22 is activated, driving the conveyor belt 2 to run at a set speed, while the blower 21 and the second power unit 7 are activated simultaneously. An empty powder box is placed on the conveyor belt 2 and transported to the clamping assembly position. When the powder box reaches directly below the feeding assembly, the conveyor belt 2 stops running, the electric control valve 9 is opened, and simultaneously, the spiral blades in the spiral conveyor hopper 12 rotate under the drive of the second power unit 7, transporting the powder in the storage hopper 5 to the injection pipe 8. The powder is injected into the powder box below through the injection pipe 8, and the injection amount is controlled by the opening time of the electric control valve 9. During the injection process, the blower 21 drives the suction wheel 20 to rotate, sucking in the dust generated during injection through the suction hood 19. The dust is filtered by the activated carbon adsorption element and then discharged, purifying the working environment. After injection is completed, the electric control valve 9 is closed, stopping the spiral conveyor. The threaded rod 18 is rotated in the opposite direction to release the stop plate 17. The conveyor belt 2 is activated, transporting the box filled with powder to the next process.
