Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, and in particular to a medicine bag conveying device for a medicine packaging machine. Background Technology
[0002] Automated dispensing machines have been in use for over 30 years. With the deepening development of information technology in my country's medical industry, hospital pharmacy automation has gradually become widespread, making pharmacy operations more efficient and standardized. Dispensing machines can automatically complete all operations of the dispensing process, from selecting the correct drugs to storing, counting, filling, and packaging them.
[0003] Current medicine bag conveying devices on the market feature linked control of conveying and packaging / printing. The packaged medicine bags need to move irregularly, sometimes stopping and sometimes moving, in coordination with the medicine bags still being packaged and printed. When the medicine bags that have not yet finished their work are being packaged and printed, the packaged medicine bags must remain stationary between the two flat belts and not fall off, and the arc-shaped wheels must remain stationary. When the medicine bags are packaged and printed, the arc-shaped wheels must start moving immediately to ensure that the flat belts have the ability to instantly start conveying the medicine bags. When the entire device cannot achieve synchronous control, the medicine bags are easily torn, causing the medicines to fall off and the packaging to fail. Utility Model Content
[0004] This utility model proposes a medicine bag conveying device for a medicine packaging machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A drug bag conveying device for a drug packaging machine includes a conveyor belt fixing plate rotatably equipped with a power arc-shaped wheel rotating shaft. One end of the power arc-shaped wheel rotating shaft is connected to a first arc-shaped driven wheel and a large arc-shaped wheel via a first synchronous arc-shaped wheel and a driving flat belt. A second arc-shaped driven wheel is rotatably mounted on the left side of the first arc-shaped driven wheel. The second arc-shaped driven wheel is connected to a first guide wheel and a third arc-shaped driven wheel via a driven flat belt. The other end of the power arc-shaped wheel rotating shaft is connected to a magnetic damper driven by a motor via a second synchronous arc-shaped wheel and a first synchronous belt.
[0007] A further preferred embodiment of this utility model is as follows: a first widened bearing, a second widened bearing, and a third widened bearing are rotatably mounted on the upper and lower sides of the contact position between the active and driven flat belts, respectively. The first widened bearing, the second widened bearing, and the third widened bearing are distributed in a triangular pattern on the upper and lower sides of the contact position between the active and driven flat belts.
[0008] A further preferred embodiment of this utility model is as follows: a drug film support plate is also fixedly installed on the conveyor belt fixing plate. The drug film support plate is located on the lower side of the contact position between the active flat belt and the driven flat belt, and the drug film support plate is provided with two through grooves. The second widened bearing and the third widened bearing are rotatably installed in the through grooves of the drug film support plate.
[0009] A further preferred embodiment of this utility model is as follows: a third arc-shaped driven wheel is rotatably mounted below the first synchronous arc-shaped wheel, and a second guide wheel is rotatably mounted below the driven flat belt between the first guide wheel and the third arc-shaped driven wheel.
[0010] A further preferred embodiment of this utility model: a third guide wheel and a fourth guide wheel are rotatably mounted above the active flat belt between the first synchronous arc-shaped wheel and the first arc-shaped driven wheel.
[0011] A further preferred embodiment of this utility model is: an arc-shaped brush is fixedly installed on the large arc-shaped wheel.
[0012] The present invention has the following advantages:
[0013] This invention utilizes the constant tension characteristic of a magnetic damper. When the medicine is being packaged or the medicine bag is not being cut, the sum of the tension and the frictional force of the flat belt medicine bag is less than the tearing force of the medicine bag. Therefore, the arc-shaped wheels do not move, and the magnetic damper only receives input power without output power. Once the medicine is packaged or the medicine bag is being cut, the tension only needs to overcome the frictional force of the flat belt medicine bag. The magnetic damper then instantly outputs power, causing the arc-shaped wheels to move instantly, thus conveying the medicine bag. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] according to Figure 1-2As shown, a medicine bag conveying device for a medicine packaging machine includes a conveyor belt fixing plate 1 with a rotatable power arc-shaped wheel rotating shaft 2. One end of the power arc-shaped wheel rotating shaft 2 is connected to a first arc-shaped driven wheel 5 and a large arc-shaped wheel 9 via a first synchronous arc-shaped wheel 3 and a driving flat belt 4. A second arc-shaped driven wheel 6 is rotatably mounted on the left side of the first arc-shaped driven wheel 5. The second arc-shaped driven wheel 6 is connected to a first guide wheel 8 and a third arc-shaped driven wheel 7 via a driven flat belt 11. The driving flat belt 4 and... The driven flat belt 11 works together to drive the medicine bag. The medicine bag enters through the active flat belt 4 and driven flat belt 11 between the first arc-shaped driven wheel 5 and the second arc-shaped driven wheel 6. The medicine bag then rotates 90° counterclockwise between the large arc-shaped wheel 9 and the first guide wheel 8. Finally, the medicine bag is moved out between the first synchronous arc-shaped wheel 3 and the third arc-shaped driven wheel 7. The other end of the rotating shaft 2 of the power arc-shaped wheel is connected to the magnetic damper 21 driven by the motor 22 through the second synchronous arc-shaped wheel 19 and the first synchronous belt 20.
[0019] A first widened bearing 13, a second widened bearing 14, and a third widened bearing 15 are rotatably mounted on the upper and lower sides of the contact position between the active flat belt 4 and the driven flat belt 11, respectively. The first widened bearing 13, the second widened bearing 14, and the third widened bearing 15 are distributed in a triangular pattern on the upper and lower sides of the contact position between the active flat belt 4 and the driven flat belt 11. This arrangement can serve to tension the driven flat belt 11.
[0020] A drug film support plate 12 is also fixedly installed on the conveyor belt fixing plate 1. The drug film support plate 12 is located on the lower side of the contact position between the active flat belt 4 and the driven flat belt 11, and the drug film support plate 12 is provided with two through slots. The second widened bearing 14 and the third widened bearing 15 are rotatably installed in the through slots of the drug film support plate 12.
[0021] The third arc-shaped driven wheel 7 is rotatably mounted below the first synchronous arc-shaped wheel 3, and the second guide wheel 16 is rotatably mounted below the driven flat belt 11 between the first guide wheel 8 and the third arc-shaped driven wheel 7.
[0022] A third guide wheel 17 and a fourth guide wheel 18 are rotatably mounted above the active flat belt 4 between the first synchronous arc-shaped wheel 3 and the first arc-shaped driven wheel 5. This arrangement can tension the active flat belt 4.
[0023] An arc-shaped brush 10 is fixedly installed on the large arc-shaped wheel 9. This arrangement allows the large arc-shaped wheel 9 to rotate freely in the radial direction and the arc-shaped brush 10 to assist the rotation of the medicine bag.
[0024] Working principle: The control motor 22 operates, and the rotation of the motor 22 generates power. The motor 22 transmits the power to the magnetic damper 21, and the magnetic damper 21 transmits the power input throughout the operation via the first synchronous belt 20. The magnetic damper 21 is connected to the second synchronous arc-shaped wheel 19 via the first synchronous belt 20 to transmit power. The second synchronous arc-shaped wheel 19 and the first synchronous arc-shaped wheel 3 are mounted on the rotating shaft 2 of the power arc-shaped wheel to achieve synchronous rotation.
[0025] After the medicine bag is printed and sealed, it passes through the scissor section and enters the active flat belt 4 and the driven flat belt 11 between the first arc-shaped driven wheel 5 and the second arc-shaped driven wheel 6. As the active flat belt 4 and the driven flat belt 11 move to the large arc-shaped wheel 9, they make a 90° turn. They continue to move with the active flat belt 4 and the driven flat belt 11, passing through the widened bearing, and reach the junction of the active flat belt 4 and the driven flat belt 11 between the first synchronous arc-shaped wheel 3 and the third arc-shaped driven wheel 7 to deliver the medicine bag.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
