Description

Technical Field

[0001] This invention relates to the field of powder supply technology, and in particular to a controllable powder supply system for large powder bags. Background Technology

[0002] Ton bag feeding is a feeding device used to increase the material feeding speed of powder coating systems, while reducing the labor intensity of workers and improving production efficiency. It employs an automated control system to automatically complete the processes of opening the ton bag, feeding material, and closing it, reducing manual intervention.

[0003] Most current powder supply equipment uses a method of hoisting and then moving large bags of tons into the main operating frame. This method requires a large lateral expansion space and consumes a lot of energy. Then, the powder with the bottom opening is discharged into the bottom discharge pipe at the bottom through a longitudinal discharge method. The dust is discharged by centrifugal air extraction. However, the discharge over a long distance will generate a lot of dust inside, which will greatly reduce the cleanliness of the inside and increase the cost of use in the later stage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the current hoisting method of powder supply equipment requires a large lateral expansion space and consumes a lot of energy. Then, the powder with the bottom opening is discharged into the bottom discharge pipe at the bottom through the longitudinal discharge method, and the dust is discharged by centrifugal air extraction. However, the discharge over a long distance will generate a lot of dust inside, which will greatly reduce the cleanliness of the inside and increase the cost of later use.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a controllable large powder bag supply system, including an outer frame and an electrically controlled centrifugal pump installed inside the outer frame. A lateral loading and unloading port is opened at the upper end of the outer side of the outer frame. An electrically controlled flip-closing cover is movably mounted on the outer side of the outer frame outside the lateral loading and unloading port. An electrically controlled lifting winch is installed on the inner side wall of the electrically controlled flip-closing cover. An electrically controlled lifting cover is installed at the lower end of the inner side of the outer frame. A bottom discharge pipe for connecting the electrically controlled centrifugal pump is installed at the bottom of the electrically controlled lifting cover.

[0006] The electrically controlled flip-close cover includes an upper movable connecting frame fixed to the upper ends of both sides of the outer frame, an outer flip-close cover inserted into the upper movable connecting frame through the upper ends of both sides, and lateral electrically controlled support rods movably installed between the outer frame and the outer flip-close cover on both sides.

[0008] A side guide rod is fixedly installed on the inner side of the outer frame by a side bracket.

[0009] The electrically controlled lifting cover includes a lifting guide cover that is slidably sleeved on the outside of the side guide rod and a longitudinally placed electrically controlled lead screw that is movably installed on the inside of the outer frame via an external bracket.

[0010] The electrically controlled tilting arm includes a movable assembly frame bolted to the side wall of the external tilting and closing cover plate, a tilting control arm movably installed inside the movable assembly frame, and an angle-adjusting strut movably installed inside the movable assembly frame for controlling the tilting control arm.

[0011] The longitudinally mounted electric control lead screw includes a bottom-mounted motor bolted to the bottom of an external bracket and a longitudinally mounted adjusting lead screw fixed to the upper drive shaft of the bottom-mounted motor via a coupling.

[0012] The bottom of the lifting guide hood is fixedly equipped with a longitudinal discharge pipe, which includes an upper feed pipe, an upper guide pipe, and a horizontal discharge pipe that cooperate with the longitudinal discharge pipe.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The controllable large powder bag supply system shown includes an outer frame 1 and an electrically controlled centrifugal pump 2 installed inside the outer frame 1. A lateral loading and unloading port 3 is provided on the upper side of the outer side of the outer frame 1. An electrically controlled flip-closing cover 4 is movably mounted on the outer side of the outer frame 1 outside the lateral loading and unloading port 3. An electrically controlled lifting winch is installed on the inner wall of the electrically controlled flip-closing cover 4. An electrically controlled lifting cover 6 is installed at the lower end of the inner side of the outer frame 1. A bottom discharge pipe 7 for connecting the electrically controlled centrifugal pump 2 is installed at the bottom of the electrically controlled lifting cover 6.

[0023] In order to coordinate the opening and closing control of the side loading and unloading port 3, the electrically controlled flip-closing cover 4 includes an upper movable connecting frame 41 fixed to the upper ends of both sides of the outer frame 1, an outer flip-closing cover 42 inserted into the upper movable connecting frame 41 through the upper ends of both sides, and a lateral electrically controlled support rod 43 movably installed between the outer frame 1 and the outer flip-closing cover 42.

[0024] The lateral electrically controlled support rod 43 is existing technology, which controls the flipping and adjustment of the external flipping and closing cover 42 by telescoping.

[0025] To facilitate side-mounted guidance, the electrically controlled lifting winch includes an electric winch 51 fixed to the side wall of the outer flip-closed cover plate 42, a fixed guide wheel frame 52 fixed to the side wall of the outer flip-closed cover plate 42 by bolts, a fixed guide wheel 44 movably installed inside the fixed guide wheel frame 52, an electrically controlled flip arm movably installed to the side wall of the outer flip-closed cover plate 42, and a movable guide wheel 45 movably installed at the non-movable connection end of the electrically controlled flip arm.

[0026] The electric winch 51 is existing technology. It drives the raising and lowering of the hoisting cable by rotating. The hoisting cable passes around the fixed guide wheel 44 and the movable guide wheel 45 respectively, and is connected to the hook at the bottom for hoisting powder bags.

[0027] Working principle: The electrically controlled tilting and closing cover 4 is tilted outwards by the operator, and then the electric winch 51 rotates to release the hoisting cable. The dust bag is then hoisted using the hoisting cable. The electric winch 51 then rotates in the reverse direction to retract the hoisting cable, raising the lower dust bag to the inside of the electrically controlled tilting and closing cover 4. The electrically controlled tilting and closing cover 4 then tilts in the reverse direction, moving the dust bag inside the outer frame 1. The electrically controlled tilting arm tilts inwards, squeezing and guiding the dust bag to the top opening of the electrically controlled lifting cover 6. As the electrically controlled lifting cover 6 is raised, the electric winch 51 releases the hoisting cable, greatly shortening the operation time and reducing the distance between the lower opening of the dust bag and the upper opening of the electrically controlled lifting cover 6. This effectively prevents dust generation when the dust bag begins to unload.

[0028] To improve stability and guidance during the lifting process, a side guide rod 8 is fixedly installed on the inner side of the outer frame 1 via a side bracket.

[0029] To facilitate electric lifting, the electrically controlled lifting cover 6 includes a lifting guide cover 61 that is slidably sleeved on the outside of the side guide rod 8 and a longitudinally placed electric control screw 62 that is movably installed on the inside of the outer frame 1 via an external bracket.

[0030] The lifting and lowering adjustment of the air guide 61 is adjusted by rotating the longitudinally placed electric control screw 62.

[0031] To facilitate lateral tilting control, the electrically controlled tilting arm includes a movable assembly frame 46 bolted to the side wall of the external tilting and closing cover plate 42, a tilting control arm 47 movably mounted inside the movable assembly frame 46, and an angle-adjusting strut 48 movably mounted inside the movable assembly frame 46 for controlling the tilting control arm 47.

[0032] The angle adjustment strut 48 is existing technology. It controls the angle adjustment of the flip control arm 47 by telescopic extension, thereby changing the gap between the movable guide wheel 45 and the external flip closing cover 42, thereby raising the position of the powder bag inside the external frame 1.

[0033] To facilitate lateral lifting and lowering adjustment, the longitudinally mounted electric control screw 62 includes a bottom motor 621 bolted to the bottom of the external bracket and a longitudinally mounted adjusting screw 622 fixed to the upper drive shaft of the bottom motor 621 via a coupling.

[0034] The bottom-mounted motor 621 is existing technology. It drives the longitudinal adjusting screw 622 to rotate, thereby controlling the lifting guide shroud 61 to rise and fall along the side guide rod 8 and the longitudinal adjusting screw 622.

[0035] In order to facilitate the diversion of dust at the bottom, the bottom of the lifting guide hood 61 is fixedly equipped with a longitudinal discharge pipe 63. The bottom discharge pipe 7 includes an upper feed pipe 64, an upper guide pipe 65 and a horizontal discharge pipe 66 that cooperate with the longitudinal discharge pipe 63.

[0036] The upper guide pipe 65 is fixed to the upper discharge port of the electrically controlled centrifugal pump 2. The high-speed rotation of the electrically controlled centrifugal pump 2 introduces the control from the upper guide pipe 65 to the upper discharge pipe 64. The negative pressure generated by the high-speed air causes the dumped dust located inside the longitudinal discharge pipe 63 to be quickly discharged into the transverse discharge pipe 66 along the upper feed pipe 64.

[0037] To enhance functionality and ensure lighting during hoisting, LED lights 9 for supplementary lighting are fixedly mounted on the side wall of the external flip-closed cover 42.

[0038] LED light 9 is existing technology, and it is automatically controlled by pressing a switch installed on the side wall of the external flip-closed cover 42.

[0039] To improve the safety and guidance of the hoisting cable, an external guide frame 10 is fixed on the side wall of the external flip-closed cover plate 42, located on both sides of the electrically controlled flip arm.

[0040] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
