Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a material feeding system for a pusher furnace. Background Technology

[0002] A pusher furnace is a high-temperature sintering equipment commonly used in industries such as electronic ceramics, magnetic materials, and powder metallurgy. During operation, the powder to be sintered needs to be loaded into saggers (the target containers), and then the pusher mechanism sends the saggers into the furnace for sintering. Traditional loading methods rely heavily on manual operation, requiring operators to load the powder into the saggers one by one, resulting in high labor intensity, low loading efficiency, and difficulty in ensuring loading accuracy. This is especially true for double-layer or multi-layer pusher furnaces, where loading of the upper and lower layers or multiple layers of saggers requires separate manual operation, making the process even more cumbersome.

[0003] Some existing technologies use screw conveyors for feeding and directly weigh the saggers to achieve quantitative loading. However, since the saggers of the pusher furnace move by the continuous movement of the pusher plate, it is difficult to accurately weigh the moving saggers, and the weighing device is easily affected by equipment vibration.

[0004] Therefore, there is an urgent need for a material feeding system that can achieve automated loading and precise feeding to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this invention is to provide a material feeding system for a pusher furnace to solve the problems of high labor intensity and low feeding accuracy in the existing technology of manual material loading.

[0006] The technical solution of this utility model is: 1. A material feeding system for a pusher furnace, comprising:

[0007] frame;

[0008] The first hopper, detachably mounted on the frame, is used to store powder.

[0009] The second hopper is movably mounted on the frame and is used to receive and temporarily store powder materials.

[0010] The first detection unit is connected to the first silo and is used to detect the weight of the first silo and the powder inside it.

[0011] The second detection unit is connected to the second hopper and is used to detect the weight of the second hopper and the powder inside it.

[0012] A feeding mechanism is located between the discharge port of the first silo and the inlet of the second silo, and is used to transport powder from the first silo to the second silo.

[0013] A movable component, disposed on the frame, is used to move the second hopper horizontally so that the outlet of the second hopper is sequentially aligned with multiple target containers.

[0014] Preferably, the first hopper is connected to the machine frame via a support frame; a material guiding component is connected to the support frame; the upper end of the material guiding component is connected to the outlet of the first hopper, and the lower end is connected to the feeding mechanism.

[0015] Preferably, the material guiding assembly includes a material guiding pipe connected to the support frame, and a transition cylinder connected to the upper end of the material guiding pipe via a flexible hose; the outlet of the first hopper is connected to the upper end of the transition cylinder.

[0016] The transition cylinder is also connected to the support frame via multiple first elastic devices, so that the transition cylinder can float in the vertical direction.

[0017] Preferably, there is a gap between the lower end of the guide tube and the feed end of the feeding mechanism.

[0018] Preferably, the first detection unit comprises multiple pressure sensors; the support frame is connected to the frame via multiple pressure sensors.

[0019] Preferably, the second detection unit comprises multiple tension sensors, which connect the second hopper to the moving component in a suspended manner.

[0020] Preferably, the moving component includes a mounting plate connected to the frame via a slide rail, and a drive device mounted on the frame and connected to the mounting plate;

[0021] The second hopper is connected to the mounting plate via the second detection unit;

[0022] The drive device can drive the mounting plate to move on the slide rail, thereby driving the second hopper to move.

[0023] Preferably, the opening and closing component is located at the discharge port of the second hopper and is used to control the opening and closing of the discharge port;

[0024] A dust cover is installed above the feed inlet of the second hopper.

[0025] Preferably, the feeding mechanism is a belt conveyor.

[0026] Compared with the prior art, the advantages of this utility model are:

[0027] (1) This utility model adopts a dual-bin structure. The first bin is used to store powder, and the second bin is used to temporarily store and quantitatively feed the powder. The weight of the powder in the second bin is detected in real time by the second detection unit to achieve accurate feeding, thus avoiding the technical problems of low accuracy and low efficiency in weighing the moving sagger.

[0028] (2) The second hopper of this utility model can move horizontally through the moving component, and can be aligned with multiple target containers in sequence for loading. It is suitable for the continuous loading needs of multiple saggers in the pusher furnace, which greatly improves the loading efficiency.

[0029] (3) The first hopper of this utility model is detachable. The storage amount of the first hopper is detected in real time by the first detection unit. When the powder is used up, the first hopper can be replaced as a whole by a forklift or other handling equipment without stopping the machine to wait for refilling, thus ensuring the continuity of production.

[0030] (4) In the material guiding assembly of this utility model, the transition cylinder is connected to the support frame through an elastic device and can float in the vertical direction, which can avoid hard collision when docking with the first hopper, and at the same time increase the tightness of the docking connection;

[0031] There is an adjustable gap between the lower end of the feed pipe and the feeding mechanism, which can adapt to the feeding requirements of powders with different flowability and prevent powder blockage or overflow. Attached Figure Description

[0039] The components include: frame 1, first hopper 2, fixed frame 21, second hopper 3, opening and closing assembly 31, dust cover 32, first detection unit 4, second detection unit 5, feeding mechanism 6, moving assembly 7, slide rail 71, mounting plate 72, drive device 73, support frame 8, guiding assembly 9, guiding pipe 91, hose 92, transition cylinder 93, first elastic device 94, and target container 10. Detailed Implementation

[0040] The present invention will be further described in detail below with reference to specific embodiments:

[0041] like Figures 1-6 As shown, the material feeding system for a pusher furnace includes a frame 1, a first hopper 2, a second hopper 3, a first detection unit 4, a second detection unit 5, a feeding mechanism 6, a moving assembly 7, and a control unit (not shown in the figure). Specifically:

[0042] The frame 1, serving as the supporting structure for the entire system, can be constructed by welding or assembling profiles, possessing sufficient strength and stability. The frame 1 has multiple mounting positions for connecting various functional components.

[0043] The first hopper 2 is detachably mounted on the frame 1 and is used to store powder to be filled. The first hopper 2 has a funnel-shaped structure that is wider at the top and narrower at the bottom, which facilitates the natural falling of powder under gravity. A fixing frame 21 is provided on the outer wall of the first hopper 2, which stably places the first hopper 2 on the support frame 8. The fixing frame 21 is also provided with a connection structure for cooperation with handling equipment (such as a forklift), such as a socket or lifting lug. When the powder in the first hopper 2 is used up, the empty hopper can be removed by a forklift and replaced with a full hopper, realizing rapid material change and ensuring the continuity of production.

[0044] The first detection unit 4 is used to detect the total weight of the first hopper 2 and the powder inside it in real time. For example... Figure 2 As shown, in a preferred embodiment, the first detection unit 4 includes multiple pressure sensors. The first hopper 2 is connected to the frame 1 via a support frame 8. The multiple pressure sensors are located at the lower end of the support frame 8 and at the connection point with the frame 1. The weight of the first hopper 2 is transmitted to the pressure sensors via the support frame 8, and the pressure sensors output a weight signal to the control unit. The control unit can determine the amount of powder in the first hopper 2 based on this weight signal. When the amount is lower than a set value, an alarm is issued to prompt the operator to prepare to replace the hopper.

[0045] A material guiding component 9 is connected to the support frame 8, used to guide the powder output from the first hopper 2 to the feeding mechanism 6. The upper end of the material guiding component 9 connects to the discharge port of the first hopper 2, and the lower end connects to the feeding mechanism 6. Specifically, as shown... Figure 2 , Figure 4As shown, the material guiding assembly 9 includes a material guiding pipe 91 connected to the support frame 8, and a transition material cylinder 93 connected to the upper end of the material guiding pipe 91 via a flexible hose 92. The outlet of the first hopper 2 is connected to the upper end of the transition material cylinder 93. The transition material cylinder 93 is also connected to the support frame 8 via multiple first elastic devices 94. The first elastic devices 94 can be springs, rubber pads, or other elastic elements, and the direction of elastic movement of the first elastic devices 94 is restricted to the up and down direction by guide rods, guide sleeves, and other devices, allowing the transition material cylinder 93 to float vertically. The function of this floating structure is that when the first hopper 2 is installed in place, its outlet contacts the upper end of the transition material cylinder 93, and the transition material cylinder 93 can adaptively adjust its position under the action of gravity to ensure a sealed fit with the outlet of the first hopper 2 and prevent powder leakage. At the same time, there is a gap between the lower end of the material guiding pipe 91 and the feed end of the feeding mechanism 6, and the size of this gap can be adjusted according to the flowability of the powder. For powders with good flowability, the gap can be reduced to prevent the powder from flowing out automatically when the feeding mechanism 6 is not started; for powders with poor flowability, the gap can be increased to ensure that the powder can fall smoothly into the feeding mechanism 6.

[0046] The feeding mechanism 6 is located between the discharge port of the first silo 2 and the inlet of the second silo 3, and is used to transport powder from the first silo 2 to the second silo 3. Figure 2 As shown, in a preferred embodiment, the feeding mechanism 6 is a belt conveyor, including a driving roller, a driven roller, a conveyor belt, and a drive motor. The conveyor belt can be a flat belt or a trough belt. The trough belt has side guards on both sides to prevent powder from spilling during conveying. Belt conveyors have the advantages of stable feeding and easy control of the feeding amount. The control unit can control the speed of the drive motor as needed to achieve fast or slow feeding, thereby improving feeding accuracy.

[0047] The second hopper 3 is movably mounted on the frame 1 to receive and temporarily store the powder material conveyed by the feeding mechanism 6. The second hopper 3 has a funnel-shaped structure, with its inlet located below the outlet of the feeding mechanism 6 to receive the powder material; an opening and closing component 31 is provided at its outlet to control the opening and closing of the outlet. A dust cover 32 is provided above the inlet of the second hopper 3 to prevent dust from spreading when the powder material falls into the second hopper 3, thereby improving the working environment and preventing external impurities from falling into the second hopper 3.

[0048] The second detection unit 5 is connected to the second hopper 3 and is used to detect the weight of the second hopper 3 and the powder inside it in real time. Figure 2 , Figure 5As shown, in a preferred embodiment, the second detection unit 5 comprises multiple tension sensors (such as S-type tension sensors) that suspend the second hopper 3 to the moving assembly 7. Specifically, the moving assembly 7 includes a mounting plate 72 connected to the frame 1 via a slide rail 71, and a drive device 73 (such as a cylinder, screw motor, etc.) mounted on the frame 1 and connected to the mounting plate 72. The second hopper 3 is suspended below the mounting plate 72 by the second detection unit 5 (tension sensors). The drive device 73 can drive the mounting plate 72 to move horizontally on the slide rail 71, thereby causing the second hopper 3 to move horizontally. When the second hopper 3 moves above the target container 10 (sagger), the opening and closing assembly 31 opens, and the powder falls into the target container 10 by gravity.

[0049] The control unit is electrically connected to the first detection unit 4, the second detection unit 5, the feeding mechanism 6, the moving assembly 7, and the opening and closing assembly 31, and is used to coordinate and control the operation of each component. The control unit controls the start and stop of the feeding mechanism 6 based on the detection signal from the second detection unit 5: when the weight of the powder in the second hopper 3 is lower than a first set value, the control unit starts the feeding mechanism 6 to transport the powder from the first hopper 2 to the second hopper 3; when the weight of the powder in the second hopper 3 reaches the second set value (i.e., the target loading amount), the control unit stops the feeding mechanism 6. Subsequently, the control unit controls the moving assembly 7 to move the second hopper 3 directly above the target container 10, and controls the opening and closing assembly 31 to open, releasing the powder into the target container 10. After one loading cycle, the opening and closing assembly 31 closes, and the second hopper 3 returns to its initial position, ready for the next feeding cycle.

[0050] like Figure 1 As shown, this material feeding system can be used in conjunction with a pusher furnace. Multiple target containers 10 (saggers) are placed on the conveying mechanism of the pusher furnace, and the target containers 10 move stepwise under the drive of the conveying mechanism. When a row of target containers 10 moves to the loading station, the second hopper 3 moves sequentially above each target container 10 under the drive of the moving component 7, completing the loading operation. For a double-layer pusher furnace, two feeding systems can be set up corresponding to the upper and lower layers respectively, or the upper layer saggers can be manually placed and then the upper layer loading can be completed by the same system.

[0051] This invention achieves automatic and precise loading of the pusher furnace sagger by adopting a dual-hopper structure, dual detection units, and a movable second hopper. This effectively reduces the intensity of manual labor, improves loading efficiency and accuracy, and facilitates quick hopper replacement, ensuring continuous production.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
