Description

Technical Field

[0001] This utility model belongs to the technical field of powder packaging equipment, specifically a balanced feeding structure for a powder packaging line. Background Technology

[0002] In the field of veterinary drug production, powder is a dry preparation obtained by mixing and pulverizing the active ingredient, a large amount of filler, and appropriate stabilizers. The main performance requirements for powder are fineness, uniformity, stability, and powder release. Traditional powders have an average particle size of about 10 μm, and this particle size is the most prone to drift. Later, researchers developed drift-free powders with an average particle size of 20–30 μm.

[0003] A search revealed that Chinese patent application number 2017215600996 discloses a powder packaging and feeding device. The device is equipped with a baffle that can regularly seal the feeding pipe as the drive shaft moves up and down, preventing the powder from accumulating and clogging at the feeding pipe. It is also equipped with an inclined cylinder, which serves two purposes: first, to keep the air pressure inside the buffer tank consistent with the outside air, ensuring smooth feeding; and second, to prevent dust generated during powder feeding from harming workers' health.

[0004] However, the powder dosage of the above-mentioned device is not precise enough, resulting in low filling accuracy and thus affecting product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a balanced feeding structure for powder packaging lines, which has the function of quantitative feeding, improves the accuracy of filling, and thus improves product quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A balanced feeding structure for a powder packaging line is provided, including a storage tank. A top cover is fixedly connected to the top of the storage tank by bolts. A motor base is fixedly connected to the top of the top cover. A stirring motor is installed on the top of the motor base. A stirring shaft is fixedly connected to the output end of the stirring motor. Stirring blades are fixedly connected to the outer wall of the stirring shaft. Multiple sets of stirring blades are provided, each set containing an equal number of blades arranged vertically. A drive wheel is fixedly connected to the top outer wall of the stirring shaft. A support plate is fixedly connected to the outer wall of the storage tank. A rotating shaft is movably connected to the top of the support plate. A driven wheel is fixedly connected to the top of the rotating shaft. A cam is fixedly connected to the bottom of the rotating shaft. The drive wheel and the driven wheel are connected by a toothed belt. A sliding groove is provided inside the storage tank. A sliding plate is installed inside the sliding groove. A connecting plate is fixedly connected to one end of the sliding plate. Two springs are fixedly connected to the outer wall of the connecting plate. A discharge port is provided inside the storage tank.

[0007] Optionally, the drive wheel is located between the motor base and the top cover, the slide plate has a through hole, and the other ends of the two springs are fixedly connected to the outer wall of the storage tank.

[0008] Optionally, a scraper is fixedly connected to one end of one or more of the stirring blades in the same group, and the bottom of the inner wall of the storage tank is conical.

[0009] Optionally, a positioning plate is fixedly connected to the outer wall of the storage tank, and the rotating shaft passes through the positioning plate.

[0010] Optionally, a discharge pipe is fixedly connected to the bottom of the storage tank, and the discharge pipe is connected to the interior of the storage tank through a discharge port. A sealing ring is provided between the top of the storage tank and the top cover.

[0011] Optionally, a bracket is fixedly connected to the bottom of the storage tank, and a support foot is fixedly connected to the bottom of the bracket, and the number of support feet is multiple.

[0012] Optionally, a conveyor platform is provided at the bottom of the storage tank, and a conveyor roller is movably connected to the inner wall of the conveyor platform. There are multiple conveyor rollers, and a conveyor belt is sleeved on the outer wall of the multiple conveyor rollers. A conveyor motor is installed on the outer wall of the conveyor platform, and the output end of the conveyor motor is fixedly connected to one end of the right-side conveyor roller.

[0013] Optionally, the bottom of each of the multiple support legs is fixedly connected to the top of the conveyor table, and the discharge pipe passes through the support.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The stirring motor operates, driving the stirring shaft and blades to rotate, which stirs the raw materials inside the storage tank, preventing accumulation and difficulty in discharge. When the stirring shaft rotates, the drive wheel at its top rotates synchronously. Since the drive wheel and driven wheel are connected by a toothed belt, the shaft, driven wheel, and cam rotate synchronously. Initially, the through-hole in the slide plate and the discharge port are misaligned. When the cam rotates, its end away from the shaft presses against the connecting plate, causing the connecting plate and slide plate to move inwards into the chute. At this time, the two springs are compressed. When the through-hole in the slide plate coincides with the discharge port, the raw materials in the storage tank can be discharged outwards through the discharge port. Subsequently, the end of the cam away from the shaft separates from the connecting plate, the two springs rebound, and the slide plate returns to its original position. At this time, the through-hole in the slide plate and the discharge port are misaligned again. This utility model has a simple structure and can achieve uniform discharge of raw materials, thereby improving product quality.

[0016] 2. One end of each of the multiple mixing blades in the same group is fixedly connected to a scraper, which not only achieves the mixing function but also scrapes off the raw material adhering to the inner wall of the storage tank, preventing it from adhering to the inner wall of the storage tank. A sealing ring is set between the storage tank and the top cover to improve the sealing of the storage tank after the top cover is installed. Multiple support feet are set at the bottom of the bracket to improve the stability of the storage tank. When the conveyor motor runs, it drives the right-side conveyor roller to rotate, thereby causing the conveyor belt to rotate counterclockwise and move the packaging bag to the bottom of the discharge pipe for filling operation.
