Description

Technical Field

[0001] The utility model relates to the technical field of medicine feeding, in particular to an automatic feeding device for powder medicines. Background Art

[0002] At present, powder drugs are usually stored in tanks during small-dose addition or small-dose quantitative packaging in other reaction processes, and then discharged through the opening at the bottom of the tank. The problem with this is that powder materials have good fluidity and strong adhesion between powders, so they are prone to agglomeration. If too much powder is loaded in the storage tank, it will easily lead to blockage of the outlet, or the powder will be discharged in large blocks during discharge, resulting in inaccurate discharge, thus affecting the addition or packaging of the drug. At the same time, the material in the storage tank needs to be replenished after it is gradually consumed, and the replenishment is usually to directly pour all the material into the tank, which is more likely to further cause the agglomeration of the material.

[0003] In view of this, this application is hereby filed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the powder material has good fluidity and the powders have strong adhesion to each other, so they are easy to agglomerate. If too much powder is loaded in the storage tank, it will easily lead to blockage of the outlet, thereby affecting the addition or packaging of the medicine. The purpose is to provide an automatic feeding device for powder medicines, which can automatically and slowly feed small doses of materials into the storage tank of the powder medicine through an additional special structure, so that the tank continuously contains materials to ensure the subsequent process transportation, but the material will not agglomerate into blocks due to excessive accumulation.

[0005] The utility model is realized by the following technical solutions:

[0006] An automatic feeding device for powder medicines, comprising a three-way screw sleeve, a metering screw is arranged in a straight tube structure of the screw sleeve, one end of the screw sleeve straight tube is connected to a storage bin, and the other end of the screw sleeve straight tube is connected to a driving structure of the metering screw;

[0007] A feeding barrel is installed on the vertical pipe of the three-way screw sleeve, and the powder medicine in the feeding barrel enters the storage bin through the rotation of the metering screw;

[0008] The top end of the vertical tube of the three-way screw sleeve is covered with a partition plate, and a plurality of feeding fixing holes are opened on the partition plate;

[0009] The bottom end of the feeding barrel is closed, and a plurality of feeding pipes connected to the feeding barrel are installed on the bottom end of the feeding barrel. The feeding pipes match the size and position of the feeding fixing holes. The feeding pipes are inserted into the feeding fixing holes to realize the fixed connection between the feeding barrel and the three-way screw sleeve.

[0010] The utility model can carry out continuous and slow automatic small-dose feeding into the storage tank of the powder medicine through the additionally designed special structure, so that the tank body continuously contains materials to ensure the subsequent process transportation, but the materials will not agglomerate into blocks due to excessive accumulation.

[0011] The utility model adds materials to a storage bin by arranging a feeding barrel, a three-way screw sleeve and a metering screw structure. First, the feeding barrel filled with powder medicine is inverted on the vertical pipe of the three-way screw sleeve, and the feeding pipe is inserted into the feeding fixing hole to realize the connection between the feeding barrel and the three-way screw sleeve, which can facilitate the rapid installation and disassembly of the feeding barrel; the powder medicine enters the straight pipe of the three-way screw sleeve from the feeding barrel through the feeding pipe, and the feeding speed and the feeding amount per unit time of the material are slowed down by the feeding pipe. The metering screw in the straight pipe rotates continuously, so as to continuously add small doses of material to the storage bin, and the spiral slices of the metering screw can also disperse the agglomerated powder medicine during rotation, so as to ensure that the material is transported to the storage bin in a loose state, and can also avoid excessive accumulation of materials in the storage bin to cause blockage of the bin bottom outlet for subsequent discharging.

[0012] In a specific embodiment, the feeding fixed hole is covered with a sealing plate, one end of which is rotatably connected to the side wall of the feeding fixed hole, and the sealing plate can be rotated downward around the rotatable end to open the feeding fixed hole when subjected to downward pressure. The utility model provides a flippable sealing plate at the feeding fixed hole. When the feeding barrel needs to be installed, the feeding tube is aligned with the sealing plate, and then the feeding tube presses the sealing plate down under the gravity of the feeding barrel to enter the feeding fixed hole. The sealing performance of the three-way screw casing can be improved by the provision of the sealing plate, especially when the material in the feeding barrel is emptied and needs to be replenished, the sealing plate can close the partition plate to prevent impurities from entering the three-way screw casing.

[0013] In a specific embodiment, the sealing plate is made of rubber material to improve the sealing performance of the partition plate. In addition, the rubber material is elastic and can avoid damage to the feeding tube when it comes into contact with it.

[0014] In a specific embodiment, a vibrator is installed on the feeding barrel, and the material in the feeding barrel can be shaken and dispersed by starting the vibrator to vibrate the feeding barrel.

[0015] In a specific implementation, the driving structure uses a servo motor.

[0016] In a specific embodiment, the top of the vertical tube has a groove, and the bottom of the groove covers the partition plate; the bottom of the feeding barrel has a boss adapted to the groove, and the bottom of the boss is installed with the feeding tube.

[0017] In a specific embodiment, a horizontal rotating rod is arranged inside the vertical tube of the three-way screw casing, and the horizontal rotating rod can rotate around its own axis. A rotating blade is installed on the horizontal rotating rod. Through the horizontal rotating rod and the rotating blade, the material discharged from the feeding pipe can be further broken up to make the material fully dispersed.

[0018] In a specific embodiment, the end of the straight tube of the three-way screw casing connected to the storage bin is tilted downward, which can provide a downward movement force for the material in the three-way screw casing, making the transportation of the material more efficient.

[0019] In a specific implementation, the three-way screw sleeve is entirely made of stainless steel to ensure the overall strength of the device.

[0020] In a specific embodiment, the feeding barrel is made of transparent plastic, which makes it easy to observe the amount of material in the feeding barrel.

[0021] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0022] 1. The automatic feeding device for powder medicine provided by the embodiment of the utility model can automatically feed small doses of powder medicine into the storage tank body of the powder medicine slowly and continuously through a special structure designed additionally, so that the tank body continuously contains materials to ensure the subsequent process transportation, but the materials will not agglomerate into blocks due to excessive accumulation;
