Description

Technical Field

[0001] This utility model relates to the field of flux production technology, and in particular to a high-efficiency and energy-saving flux production line powder lifting device. Background Technology

[0002] In the field of flux production, powder lifting devices are one of the key pieces of equipment to ensure the smooth operation of the production process. Their performance directly affects production efficiency and energy consumption.

[0003] A search of Chinese patent publication number CN218318891U reveals a novel bucket elevator for flux production. The technical solution includes an elevator box, a feed pipe, and a spray box. A drive wheel and a driven wheel are rotatably installed inside the elevator box, and a lifting belt connects the drive wheel and the driven wheel. The lifting belt is equipped with evenly distributed buckets. The feed pipe is installed at the lower part of one side end face of the elevator box, and a feed inlet is provided at the upper end of the feed pipe.

[0004] Based on the above research and existing technology, it was found that in existing powder lifting devices, due to the adhesive properties of the powder itself, some powder often adheres tightly to the inner wall of the hopper during the unloading process. When the hopper completes one lifting and unloading cycle and returns to the bottom to scoop material again, this residual powder will participate in the cycle again, forcing the equipment to repeatedly lift the material already lifted, resulting in a significant waste of energy. Furthermore, the long-term accumulation of residual powder may affect the normal operation of the equipment, reduce its service life, and increase maintenance costs. In contrast, this utility model presents a high-efficiency and energy-saving flux production line powder lifting device. By incorporating a tiltable pusher plate component in the inner liner assembly, when the hopper shovel tilts to the discharge port area, the pusher plate body automatically pushes outward under the cooperation of the spring assembly and the inclined surface of the limiting baffle, forming a forced unloading action, effectively solving this long-standing problem of incomplete unloading in the industry. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a high-efficiency and energy-saving flux production line powder lifting device, which adopts a modular inner liner design (inner liner body / fixing bolt / hopper shovel threaded hole), and realizes quick assembly and disassembly of the inner liner body through a single through-type fixing bolt.

[0006] The technical solution to achieve the purpose of this utility model is: a high-efficiency and energy-saving flux production line powder lifting device, including a lifting machine body, a drive mechanism, a material guiding device and a feeding port, and also includes;

[0007] A hopper assembly, the hopper assembly including an arc-shaped hopper shovel and a connecting plate;

[0008] The inner liner assembly is provided inside the hopper shovel and is detachable from the bottom surface of the hopper shovel.

[0009] The inner liner assembly includes an outwardly flipping push plate component, and the inner liner assembly includes an inner liner body that is in close contact with the inner wall of the hopper shovel.

[0010] The push plate component includes: a push plate body hinged to the opening side of the inner liner body, which can be rotated from 0 to 120° by a torsion spring assembly;

[0011] It also includes multiple sets of spring assemblies located at the bottom of the push plate body; a limiting baffle installed at an incline on the bottom surface inside the inner liner body, the inclined surface of the limiting baffle matching the movement trajectory of the spring assembly, when the push plate body flips outward, the spring assembly slides along the inclined limiting surface of the limiting baffle and compresses and deforms.

[0012] In some embodiments, the driving mechanism includes a vertically arranged closed-loop conveyor belt body inside the hoist body, a drive motor is arranged on the outside of the hoist body, and the output rod of the drive motor is connected to the inside of the hoist body and the conveyor belt body for driving connection. Multiple sets of connecting plates are uniformly fixed on the outer surface of the conveyor belt body.

[0013] In some embodiments, the inner liner body has a threaded hole at one end near the inner side of the hopper shovel, and a fixing bolt that penetrates the inside of the hopper shovel is threadedly connected to the outer side of the hopper shovel, and the fixing bolt is threadedly connected to the inner liner body.

[0014] In some embodiments, a feed inlet communicating with the interior of the elevator body is installed at one bottom end of the elevator body, and a downwardly inclined discharge port is opened on the other side of the top of the elevator body, and a material guide device for downward discharge is installed at the opening of the discharge port.

[0015] In some embodiments, a C-shaped maintenance platform is provided on the side of the material guiding device, and the maintenance platform is fixed to the outer top of the elevator body by a support frame.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this invention incorporates a reversible pusher plate component (pusher plate body / torsion spring assembly / spring assembly / limiting baffle) within the inner hopper assembly. When the hopper shovel flips to the discharge port area, the pusher plate body automatically pushes outward under the cooperation of the inclined surfaces of the spring assembly and the limiting baffle, resulting in a forced unloading action. This structure directly solves the problem of incomplete unloading caused by material adhesion in traditional devices, ensuring that the powder completely detaches from the hopper and avoiding energy waste caused by secondary recycling.

[0018] Secondly, this utility model adopts a modular inner liner design (inner liner body / fixing bolt / hopper shovel threaded hole), which enables quick assembly and disassembly of the inner liner body through a single through-type fixing bolt. This structure directly solves the problem of having to replace the entire welded hopper during maintenance. Technicians only need to loosen the fixing bolt to complete the inner liner replacement, significantly shortening maintenance time.

[0019] Thirdly, the drive mechanism of this utility model adopts a direct drive between the conveyor belt body and the drive motor, combined with evenly distributed bucket shovels, to form a continuous vertical lifting path within the main body of the elevator. This structure directly solves the problem of discontinuous material lifting caused by transmission gaps in traditional chain elevators, achieving uniform and efficient transportation of powder materials.

[0020] Fourthly, this utility model features a C-shaped maintenance platform on the side of the material guiding device, with its support frame rigidly connected to the top of the hoist body. Simultaneously, the guardrail structure of the top manual platform surrounds the discharge port area. This structure directly solves the safety hazard of limited operating space during high-altitude maintenance, providing stable support and omnidirectional protection for technicians.

[0021] In summary, this utility model improves upon the systemic defects of the prior art, such as material residue during unloading, cumbersome maintenance, low transportation efficiency, high maintenance risks, and disordered material flow. Attached Figure Description

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0031] This utility model provides an improved, highly efficient, and energy-saving flux production line powder lifting device. The technical solution of this utility model is as follows:

[0032] like Figure 1 - Figure 5 As shown, a high-efficiency and energy-saving flux production line powder lifting device includes a lifting machine body 1, a drive mechanism, a material guiding device 2, a feed inlet 3, a hopper assembly, an inner liner assembly, and a pusher plate component. The hopper assembly includes an arc-shaped hopper shovel 5 and a connecting plate 501; the inner liner assembly is disposed inside the hopper shovel 5 and is detachable from the inner bottom surface of the hopper shovel 5; the pusher plate component is disposed inside the inner liner assembly and can be flipped outwards; the inner liner assembly includes an inner liner body 6 that is tightly attached to the inner wall surface of the hopper shovel 5. The pusher component includes a pusher body 7 hinged to the opening side of the inner liner body 6, which can rotate from 0 to 120° via a torsion spring assembly 701; it also includes multiple sets of spring assemblies 702 located at the bottom of the pusher body 7; and a limiting baffle 703 inclinedly installed on the inner bottom surface of the inner liner body 6. The inclined surface of the limiting baffle 703 matches the movement trajectory of the spring assembly 702. When the pusher body 7 rotates outward, the spring assembly 702 slides along the inclined limiting surface of the limiting baffle 703 and undergoes compression deformation. Through the cooperation between the pusher body 7 and the inclined surface of the limiting baffle 703, a dynamic self-cleaning mechanism is formed to prevent powder from adhering to the inner wall during the rotation process.

[0033] like Figure 2As shown, in one embodiment, the driving mechanism includes a closed-loop conveyor belt body 4 vertically disposed inside the elevator body 1. A drive motor 401 is disposed on the outside of the elevator body 1, and the output rod of the drive motor 401 connects the inside of the elevator body 1 to the conveyor belt body 4 for driving connection. Multiple sets of connecting plates 501 are uniformly fixed on the outer surface of the conveyor belt body 4. Through the arrangement of the conveyor belt body 4 and the drive motor 401 in the driving mechanism, the drive motor 401 drives the conveyor belt body 4 to rotate, thereby driving multiple sets of hopper assemblies to circulate up and down inside the elevator body 1 to lift and transport materials, realizing the function of efficient lifting and transportation of powder in the flux production line; the closed-loop design of the conveyor belt body 4 enhances the operational stability and reduces the risk of leakage during the material lifting process.

[0034] like Figure 4 and Figure 5 As shown, in one embodiment, the inner liner body 6 has a threaded hole at one end near the inner side of the hopper shovel 5, and a fixing bolt 601 that penetrates the interior of the hopper shovel 5 is threadedly connected to the outer side of the hopper shovel 5. The fixing bolt 601 and the inner liner body 6 are threadedly fixedly connected. The inner liner body 6, the hopper shovel 5, and the fixing bolt 601 allow the inner liner body 6 to be detachably installed inside the hopper shovel 5, facilitating its installation and removal. When the inner liner body 6 is worn or needs cleaning, it can be easily removed, achieving convenient maintenance and replacement.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, a feed inlet 3 communicating with the interior of the elevator body 1 is installed at one bottom end of the elevator body 1, and a downwardly inclined discharge outlet 101 is opened on the other side of the top of the elevator body 1. A material guide device 2 for downward discharge is installed at the opening of the discharge outlet 101. A manual platform located at the material guide device 2 is installed on the top outer side of the elevator body 1. The manual platform is composed of a bottom support plate and a bottom guardrail. Through the setting of the feed inlet 3, the discharge outlet 101 and the material guide device 2, the flux production line powder is poured into the interior bottom surface of the elevator body 1 from the feed inlet 3, and after being lifted, it is discharged outward from the discharge outlet 101 through the material guide device 2, realizing the orderly entry and exit and conveying of powder. The setting of the manual platform makes it convenient for technicians to climb to the top of the elevator body 1 to operate and maintain the material guide device 2 installed at the discharge outlet 101 on the top of the elevator body 1.

[0036] like Figure 1 and Figure 3As shown, in one embodiment, a C-shaped maintenance platform 8 is provided on the side of the material guiding device 2. The maintenance platform 8 is fixed to the top outer side of the elevator body 1 by a support frame. The maintenance platform 8 provides a safe and stable maintenance space for technicians. When it is necessary to maintain components such as the material guiding device 2, technicians can stand on the maintenance platform 8 to perform the operation, thus facilitating equipment maintenance.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the pusher plate body 7 of the pusher plate component achieves 0-120° rotation via a torsion spring assembly 701, and multiple sets of spring assemblies 702 are provided at the bottom of the pusher plate body 7. A limit baffle 703 is installed at an angle on the bottom surface of the inner liner body 6. With the pusher plate component, when the hopper assembly moves upward, the powder falls onto the pusher plate component. The pusher plate component is pressed down by the gravity of the material, squeezing the inside of the hopper shovel 5. When the hopper shovel 5 rotates downward from the top with the drive mechanism, the pusher plate component generates a secondary pushing action during the hopper rotation and unloading stage. This prevents some material remaining inside the hopper shovel 5 from falling back into the bottom surface of the elevator body 1 when it is thrown outward, thus improving unloading efficiency and reducing material residue.

[0038] The working principle and usage process of this utility model: The flux production line powder is poured into the bottom of the elevator body 1 from the feed inlet 3. The drive motor 401 of the drive mechanism drives the conveyor belt body 4 to move up and down reciprocally. The conveyor belt body 4 drives the evenly distributed hopper components on its surface to dig the powder from the bottom of the elevator body 1. When the hopper components move upward, the powder scooped into the hopper shovel 5 will fall onto the push plate component inside the hopper shovel 5. The push plate component is pressed down by the gravity of the material and squeezes the push plate component into the hopper shovel 5. When the hopper shovel 5 is flipped downward from the top by the drive mechanism, the powder inside the hopper shovel 5 will tilt downward and be thrown towards the discharge port 101. As the tilted bottom surface of the discharge port 101 flows into the guiding device 2, the push plate component generates a secondary pushing action during the hopper flipping and unloading stage to push out the remaining material and avoid material residue. Finally, the powder is discharged outward from the guiding device 2. When the equipment requires maintenance, technicians can operate and repair the relevant components through the manual workstation and maintenance platform 8.

[0039] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
