Automatic rare earth oxide filling machine

Abstract

This utility model relates to an automatic rare earth oxide filling machine, including a rare earth oxide filling frame, a star-shaped unloading valve, a ton bag conveyor line, a ton bag lifting mechanism, and a filling lifting mechanism. The filling lifting mechanism drives the inner spiral cylinder to rise and fall via a filling lifting frequency conversion motor, and adjusts the height difference between the unloading port and the material accumulation in real time based on weighing feedback. Under the action of the outer spiral cylinder lifting cylinder, the outer spiral cylinder cooperates with the conical unloader to form a closable fan-shaped unloading port to prevent material leakage. The filling spiral conveys the material from the filling conical cylinder to the ton bag. This filling machine effectively solves the problems of material leakage, dust, and high energy consumption of traditional equipment, achieves accurate filling, reduces energy consumption, improves the stability of the mechanism, and improves the filling efficiency and quality of rare earth oxides.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 2 This application provides an automatic rare earth oxide filling machine, characterized in that it includes a rare earth oxide filling frame 1, a star-shaped unloading valve 2, a ton bag conveyor line 3, a ton bag lifting mechanism 4, and a filling lifting mechanism 5; the filling lifting mechanism 5 includes a filling lifting frame 51, a filling lifting variable frequency motor 52, a filling lifting slider 53, a filling conveying variable frequency motor 54, a filling lifting counterweight 55, a filling screw 56, a screw inner cylinder 57, a screw outer cylinder 58, a screw outer cylinder lifting cylinder 59, and a conical unloader 510; the filling lifting variable frequency motor 52 drives the filling lifting slider 53 along the filling lifting frame. The frame 51 is raised and lowered, and the filling lifting slider 53 is connected to the spiral inner cylinder 57; the spiral outer cylinder lifting cylinder 59 is fixed on the large flange of the spiral inner cylinder 57, and its piston rod is connected to the spiral outer cylinder 58, driving the spiral outer cylinder 58 to rise and fall relative to the spiral inner cylinder 57; the conical unloader 510 is fixed to the bottom of the spiral inner cylinder 57, and the spiral outer cylinder 58 and the conical unloader 510 cooperate to form an openable / closeable fan-shaped unloading port; the filling conveying variable frequency motor 54 is driven and connected to the filling spiral 56, which is located inside the spiral inner cylinder 57; the filling lifting counterweight 55 is connected to the filling lifting slider 53.

[0023] The filling and lifting mechanism 5 also includes a filling conical cylinder 511, which is fixed to the top of the spiral inner cylinder 57 and connected to the outlet of the star-shaped unloading valve 2. The filling and lifting variable frequency motor 52 is driven and connected to the filling and lifting slider 53 through a worm gear hollow reducer, which has a self-locking function. The filling and lifting counterweight 55 is connected to the filling and lifting slider 53 through a double-row chain to balance the load of the filling and lifting mechanism 5. The spiral inner cylinder 57, the conical unloader 510, and the filling and lifting slider 53 move up and down synchronously. The opening state of the fan-shaped unloading port is: the spiral outer cylinder 58 rises under the drive of the spiral outer cylinder lifting cylinder 59 and separates from the conical unloader 510; the closing state is: the spiral outer cylinder 58 descends and comes into contact with the conical unloader 510.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Working principle: This filling machine achieves dynamic filling control through the filling lifting mechanism 5. The specific process is as follows:

[0026] Discharge port adjustment: Before filling, the spiral outer cylinder lifting cylinder 59 drives the spiral outer cylinder 58 to rise and separate from the conical unloader 510 to form a fan-shaped discharge port. The ton bag lifting mechanism 4 lifts the ton bag to the filling position.

[0027] Height Adaptation: The filling lifting variable frequency motor 52 drives the filling lifting slider 53 to descend, so that the conical unloader 510 is close to the bottom of the ton bag. The filling conveying variable frequency motor 54 starts and drives the filling screw 56 to convey the material from the filling conical material cylinder 511 into the ton bag.

[0028] Dynamic compensation: As material is filled, the weighing sensor provides real-time feedback of weight data. The control system calculates the material accumulation height according to a preset algorithm and drives the spiral inner cylinder 57 to rise slowly through the filling lifting variable frequency motor 52, keeping the distance between the discharge port and the material surface within 5-10cm to reduce dust.

[0029] Leakage prevention design: When the filling is close to the target weight, the filling conveyor variable frequency motor 54 reduces the speed to achieve slow material replenishment. After the set weight is reached, the motor stops, and the spiral outer cylinder lifting cylinder 59 drives the spiral outer cylinder 58 to descend, which fits tightly with the conical unloader 510 to seal the unloading port and prevent residual material from dripping.

[0030] Reset and Cycle: After filling is completed, the filling lifting mechanism 5 rises to the initial position, and the ton bag descends to the pallet, completing one work cycle.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
