Description

Technical Field

[0001] This utility model relates to the field of seaweed chemical equipment technology, specifically an automatic feeding device for seaweed acid extraction. Background Technology

[0002] Alginic acid is a natural polysaccharide extracted from brown algae (such as kelp and giant kelp). It is widely used in food, medicine, textiles and other fields. In its extraction process, the crushed and washed seaweed raw material is first put into an extraction tank containing alkaline solution for reaction.

[0003] Traditional automatic feeding devices for alginate extraction often rely on manual weighing or a rough feeding method with fixed time and volume, which leads to large errors and poor batch consistency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for alginic acid extraction, which solves the problem that traditional automatic feeding devices for alginic acid extraction rely heavily on manual weighing or use a timed and volume-based coarse feeding method, resulting in large errors and poor batch consistency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic feeding device for alginate extraction, comprising a base, four sets of support legs fixedly installed on the lower surface of the base, a bracket fixedly installed on the upper surface of the base, a first mounting plate fixedly installed inside the bracket, a storage hopper fixedly installed inside the first mounting plate, a conveying mechanism provided on the lower surface of the storage hopper, the inlet end of the conveying mechanism being located inside the storage hopper, and a weighing and feeding mechanism provided inside the base, the inlet end of the weighing and feeding mechanism being located on the lower surface of the conveying mechanism.

[0006] Furthermore, the conveying mechanism includes a connecting pipe, the inner bottom of the storage hopper is fixedly installed with the connecting pipe, the lower surface of the connecting pipe is fixedly installed with a feeding box, and the inside of the feeding box is rotatably connected with a rotating rod.

[0007] Furthermore, a motor is fixedly installed on the outer surface of the feeding box, the output end of the motor is connected to one end of the rotating rod, and an auger is sleeved on the outer surface of the rotating rod.

[0008] Furthermore, the weighing and feeding mechanism includes a weighing hopper, which is fixedly installed inside the base. One end of the weighing hopper abuts against the discharge port of the feeding box. A fixing plate is sleeved on the outer surface of the weighing hopper, and two sets of first fixing plates are fixedly installed on the outer surface of the weighing hopper.

[0009] Furthermore, two sets of first connecting plates are fixedly installed on the upper surfaces of the two sets of first fixed plates, a first connecting rod is fixedly installed between the two sets of first connecting plates, a second connecting plate is sleeved on the outer surface of the first connecting rod, and a cylinder is fixedly installed on the outer surface of the second connecting plate.

[0010] Furthermore, a mounting bracket is fixedly installed at the output end of the cylinder, and a rotating shaft is fixedly installed between the mounting brackets. Two sets of door panels are movably connected to the bottom of the weighing hopper. A first connecting member is fixedly installed inside the door panel, and one end of the first connecting member is sleeved on the outer surface of the rotating shaft.

[0011] Furthermore, two sets of fixing blocks are fixedly installed on the outer surface of the weighing hopper, and two sets of second mounting plates are fixedly installed on the lower surface of the fixing blocks. One end of the second mounting plate is connected to the upper surface of the fixing plate. A second connecting rod is fixedly installed inside the second mounting plate. Two sets of second connecting members are sleeved on the outer surface of the second connecting rod. One end of the second connecting member is connected to the bottom of the door panel.

[0012] This utility model has the following beneficial effects: (1) In this utility model, the weighing hopper bears the weight of the material fed in by the conveying mechanism above in real time. When the weight of the material in the weighing hopper reaches the preset value, the external control system issues an instruction. After receiving the instruction, the cylinder retracts its output end and pulls the first connecting piece connected to the door panel through the mounting bracket and the rotating shaft. This pulling action forces the two door panels to use the second connecting rod as the fulcrum, overcome the constraint of the second connecting piece, and flip open to the outside to form a discharge port. The material in the weighing hopper is accurately and quickly discharged through the discharge port under the action of gravity and enters the next process. After the discharge is completed, the cylinder reverses its action and pushes the door panel to close, preparing for the next feeding cycle. This achieves the ability to accurately control the amount of material fed each time, effectively avoiding the error caused by manual feeding. It avoids the situation where the existing technology relies on manual weighing or adopts a rough feeding method of timed and fixed volume when automatically feeding, which leads to large errors and poor batch consistency.

[0013] (2) The present invention starts the motor by starting the starting device, which drives the rotating rod and the auger on it to rotate in the feeding box. The alginic acid raw material stored in the storage hopper falls into the feeding box under the action of gravity, and is conveyed stably and continuously by the rotating auger. The conveyed material is discharged from the discharge port of the feeding box and falls into the weighing hopper directly below, thereby achieving the effect of conveying materials.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

This pulling action forces the two door panels 710 to use the second connecting rod 714 as a fulcrum, overcoming the constraint of the second connecting piece 715, and flipping open outward to form a discharge port. The material in the weighing hopper 701 is accurately and quickly discharged through the discharge port under the action of gravity, entering the next process. After the discharge is completed, the cylinder reverses its action, pushing the door panel to close, preparing for the next feeding cycle. This achieves precise control of the amount of material fed each time, effectively avoiding the error caused by manual feeding. It also avoids the situation where existing technologies rely heavily on manual weighing or use a rough feeding method with fixed time and volume when automatically feeding, which leads to large errors and poor batch consistency.
