Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a powder dual-feeding device. Background Technology

[0002] In modern industrial production, alumina powder is an important basic material widely used in ceramics, electronics, chemicals, and other fields. Efficient and stable material transport is one of the key factors ensuring a smooth production process.

[0003] Currently, vacuum feeders are commonly used for conveying alumina powder. These feeders utilize the principle of vacuum to draw powder from a storage container to a discharge hopper via pipes, and then transport it to the next process step. This conveying method offers advantages such as high automation, fast conveying efficiency, and minimal material contamination, and is therefore widely used in alumina powder production.

[0004] However, vacuum conveyors also have some potential shortcomings in actual use. For example, key components such as the vacuum pump and pipelines may fail due to prolonged operation, material blockage, or mechanical malfunction. Once a vacuum conveyor malfunctions, the entire conveying system will be forced to stop, leading to production interruption and consequently affecting production efficiency and product quality.

[0005] To address these issues, some companies have attempted to use a single backup conveyor, but this approach suffers from drawbacks such as high cost, large space requirements, and complex switching procedures. Additionally, some companies have adopted manual handling as an emergency measure, but manual handling is not only labor-intensive and inefficient, but also prone to contaminating materials and fails to meet the continuous requirements of large-scale production.

[0006] Therefore, how to provide a reliable backup conveying solution to cope with emergencies such as vacuum feeder failure while ensuring the efficiency and stability of alumina powder conveying is a technical problem that urgently needs to be solved in the field of alumina powder conveying. Utility Model Content

[0007] In view of the problems existing in the prior art, the present invention provides a powder dual feeding device, which can effectively solve the problems existing in the prior art.

[0008] The technical solution of this utility model is:

[0009] According to one aspect of the present invention, the device includes: a frame, a sealing cover covering the top of the frame, a discharge hopper fixedly disposed at the lower end of the frame, and a vacuum feeder connected to the discharge hopper mounted at one end of the sealing cover; a feeding platform extending along the length of the frame, the orthographic projection area of ​​the sealing cover covering a portion of the feeding platform, and one end of the feeding platform connecting to the discharge hopper, and an inlet formed at one end of the sealing cover for exposing the feeding platform; and a push plate movable forward and backward, one end of the push plate being equipped with a driving device for its movement; by moving the push plate, material is pushed into the discharge hopper.

[0010] Furthermore, the feeding platform is provided with a support plate extending along its length, the driving device is a cylinder, and a mounting seat for mounting the cylinder is fixed on the support plate.

[0011] Furthermore, at least one guide groove is provided on each of the left and right sides of the push plate, and guide ribs are provided on the left and right ends of the inner side of the sealing cover extending into the guide groove.

[0012] Furthermore, the lower end of the pusher plate near the discharge hopper has an inwardly inclined slope.

[0013] Furthermore, it also includes a limiting plate, which is detachably fixed to the support plate. When the push plate is in the initial position, one end of the limiting plate abuts against the push plate.

[0014] Furthermore, it also includes a baffle that divides the sealing cover into a first feeding area and a second feeding area, and a feeding port is formed below the baffle.

[0015] Furthermore, it also includes an upper cover for shielding or exposing the material feeding platform, the upper cover being disposed on the material inlet, the inner circumference of the material inlet forming a limiting rib, the lower end face of the limiting rib abutting against the push plate, and the upper end face of the limiting rib abutting against the upper cover.

[0016] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0017] Firstly, this utility model achieves a dual-mode feeding function by setting up a frame, sealing cover, discharge hopper, vacuum feeder, feeding platform, pusher plate, and drive device. When the vacuum feeder is working normally, the system can automatically complete powder conveying; when the vacuum feeder malfunctions, the material can be manually or semi-automatically pushed into the discharge hopper via the pusher plate as a backup feeding method. Even when the vacuum feeder fails, continuous material conveying can still be guaranteed, avoiding production line downtime. Integrating the main feeding and backup feeding systems into the same device avoids the problems of large space occupation and complex switching of traditional backup equipment.

[0018] Secondly, the precise positioning of the push plate movement is achieved through the cooperation of the guide groove and guide ribs, preventing the push plate from deviating or jamming during movement, thus improving the stability and safety of the pushing process.

[0019] Third, the push plate has an inwardly inclined slope on the side near the discharge hopper, which helps to push the material into the discharge hopper more thoroughly, reduce residue, improve material utilization, and avoid waste.

[0020] Fourth, by setting a detachable limit plate, a physical limit is provided when the push plate returns to the initial position, preventing the push plate from retracting excessively, improving the control accuracy and safety of the system, and facilitating maintenance and adjustment.

[0021] Fifth, by setting the top cover and limiting ribs, the feed inlet can be closed when the push plate is not in use to prevent dust leakage and improve sealing and operational safety; at the same time, the limiting ribs play a positioning role for the push plate and the top cover, enhancing structural stability.

A discharge hopper 3 is fixedly installed at the lower end of the frame 1, and the discharge port 31 of the discharge hopper 3 is connected to the next process. A vacuum feeder 4 connected to the discharge hopper 3 is installed at one end of the sealing cover 2; the vacuum feeder 4 is a direct application of existing technology, and its principle will not be described in detail here. A feeding platform 11 is provided along the length of the frame 1, the orthographic projection area of ​​the sealing cover 2 covers part of the feeding platform 11, and one end of the feeding platform 11 is connected to the discharge hopper 3. An inlet 20 is formed at one end of the sealing cover 2 to expose the feeding platform; it also includes a pusher plate 6 that can move forward and backward, and a drive device 7 is installed at one end of the pusher plate 6 to make it move; by moving the pusher plate 6, the material is pushed into the discharge hopper 3. A support plate 111 extends along the length of the feeding platform 11. The driving device 7 is a cylinder, and a mounting seat 13 for mounting the cylinder is fixed on the support plate 111. The cylinder is a direct application of existing technology, and its principle will not be described in detail here. Specifically, a connector 61 for connecting the cylinder is provided in the middle of the push plate 6. A limiting plate 12 is also included, which is detachably fixed to the support plate 111. When the push plate 6 is in the initial position, one end of the limiting plate 12 abuts against the push plate 6. The limiting plate 12 is fixedly connected to the support plate 111 by bolts.

[0032] Please see Figures 1 to 5 At least one guide groove 62 is provided on each of the left and right sides of the push plate 6, and guide ribs 21 are provided on the left and right ends of the inner side of the sealing cover 2 extending into the guide grooves 62. Through the cooperation of the guide grooves 62 and the guide ribs 21, the precise positioning of the push plate 6 is achieved, preventing the push plate 6 from deviating or getting stuck during the movement, and improving the stability and safety of the pushing process.

[0033] Please see Figure 4 and Figure 5The lower end of the push plate 6 near the discharge hopper 3 has an inwardly inclined slope 63. The inwardly inclined slope 63 on the side of the push plate 6 near the discharge hopper 3 helps to push the material more thoroughly into the discharge hopper 3, reduce residue, improve material utilization, and avoid waste.

[0034] Please see Figure 3 It also includes a baffle 14, which divides the sealing cover 2 into a first conveying area and a second conveying area. A conveying port 10 is formed below the baffle 14. By setting the baffle 14, some material is prevented from falling onto the discharge platform 11 when the vacuum feeder 4 is conveying materials.

[0035] Please see Figures 1 to 3 It also includes an upper cover 5 for shielding or exposing the material feeding platform 11. The upper cover 5 covers the feed inlet 20, and a limiting rib 22 is formed on the inner circumference of the feed inlet 20. The lower end face of the limiting rib 22 abuts against the push plate 6, and the upper end face of the limiting rib 22 abuts against the upper cover 5. A handle 51 is fixedly provided on the upper end of the upper cover 5. By setting the upper cover 5 and the limiting rib 22, the feed inlet 20 can be closed when the push plate 6 is not in use, preventing dust leakage and improving sealing and operational safety; at the same time, the limiting rib 22 plays a positioning role for the push plate 6 and the upper cover 5, enhancing structural stability.

[0036] Working principle:

[0037] This utility model has two feeding modes:

[0038] Vacuum feeder 4 feeding mode (main mode): When the vacuum feeder 4 is working normally, the top cover 5 is placed on the inlet 20, covering the discharge platform 11. The vacuum feeder 4 starts, and the powder material is sucked into the first conveying area inside the sealed cover 2 through the pipeline by negative pressure. Under the action of gravity, the material is conveyed from the discharge port 31 of the inlet / outlet hopper 3 to the next process, realizing automatic and continuous powder feeding.

[0039] Pusher Plate 6 Feeding Mode (Backup Mode): When the vacuum feeder 4 malfunctions and cannot operate, open the top cover 5 to expose the discharge platform 11. Place powdered material (such as bagged powder) onto the discharge platform 11 through the inlet 20. Activate the drive unit 7 (cylinder), which drives the pusher plate 6 to move smoothly forward (towards the discharge hopper 3) along the discharge platform 11 with the cooperation of the guide ribs 21 and the guide groove 62. The pusher plate 6 pushes the material, allowing it to slide into the discharge hopper 3 through the feed inlet 10. The inclined surface 63 at the front end of the pusher plate 6 helps to completely push the material into the discharge hopper 3, reducing residue. After one feeding operation, the drive unit 7 moves the pusher plate 6 backward to return to the initial position until the pusher plate 6 abuts against the limit plate 12 and stops. At this point, material can be placed again for the next feeding operation. This mode can be quickly switched when vacuum feeding fails, ensuring production continuity.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
