Description

[0001] The present application relates to a medical food filling equipment, in particular to a laboratory injection bottle filling, belonging to the field of food and drug packaging machinery. BACKGROUND

[0002] The existing powder dispensing machine adopts the powder hopper plus screw rod mode to dispense powder, and the screw rod and hopper volume are relatively large. For example, the Chinese utility model patents with publication numbers CN208264662U and CN217598886U disclose a "full-automatic powder filling machine" and a "full-automatic bottle powder filling machine with weighing function", which have a relatively large equipment volume and are installed on the ground, making it difficult to use in small laboratories.

[0003] The existing powder dispensing machine has a large residual amount due to the limitations of the screw rod and powder hopper mechanical structure, and thus cannot be used when the raw material is scarce during the experimental stage.

[0004] The existing dispensing machine has a single function, and the powder dispensing machine can only dispense powder medicine, and the liquid dispensing machine can only dispense liquid medicine. During the research stage in the laboratory, different dispensing machines are needed for different medicine forms and different medicine researches. At present, one dispensing machine cannot meet the dispensing of liquid and powder medicines. SUMMARY

[0005] In order to meet the dispensing of different medicine forms during the laboratory research stage, and to overcome the difficulties of small laboratory space, labor-intensive manual dispensing by experimenters, and low dispensing precision and efficiency, the present application provides a small multifunctional dispensing machine for a laboratory desktop. The desktop type micro multifunctional dispensing machine provided by the present application can be placed on the desktop of a laboratory in a class A environment, or placed in an isolator or biological safety cabinet for use. It can meet the dispensing of powder medicine and liquid medicine, has a small volume and light weight, and is convenient to install and transport.

[0006] The technical solution adopted by the present application to solve the technical problems is that the powder dispensing form of air flow cannula is adopted to replace the traditional powder hopper and screw rod, thereby reducing the size of the dispensing mechanism. Clean compressed gas and vacuum technology are used to suck and dispense the medicine powder, and a peristaltic pump is used to dispense liquid medicine, which can prevent the damage of shear force to the medicine property of biological medicine during dispensing.

[0007] The beneficial effect of the present application is that two traditional large production type dispensing machine devices are replaced by a small laboratory device, reducing the use area of the laboratory and reducing the cost of laboratory equipment, and due to the small size and light weight of the device, it is easy to move and can be used in different laboratories for different drug research, and has better utilization efficiency compared with traditional large equipment.

[0016] Example 1

[0017] The composition of the sterile laboratory micro multifunctional split machine includes a case assembly 1, the case assembly 1 is provided with a feeding small turntable assembly 2, a peristaltic pump assembly 3, a powder box assembly 4, a split needle assembly 5, a rubber plug vibration hopper assembly 6, a plug pressing assembly 7, a bottle receiving disc assembly 8, a star wheel assembly 9, and a control system 10.

[0018] The feeding small turntable assembly 2 is provided with 1-10 motors, and the rotation of the motors can make the turntable 202 on the feeding small turntable assembly 2 rotate clockwise or counterclockwise.

[0019] According to the shape of the medicine to be filled, different formulations need to be made for the control system 10, powder medicine design powder filling program, liquid filling design liquid filling program, and experimenters can download the corresponding formulations through HMI 10 to complete the split of different medicines.

[0020] Example 2

[0021] During the experiment, the operator places the penicillin bottle 101 on the feeding small turntable 2, when the turntable 202 rotates clockwise, the penicillin bottle 101 is arranged into a single column into the star wheel assembly 9 through the centrifugal principle of the rotation of the feeding small turntable assembly 2 and the joint action of the feeding guardrail 201, the star wheel 901 on the star wheel assembly 9 is processed with multiple circular teeth, when the motor on the star wheel assembly 9 rotates, the star wheel 901 will rotate clockwise, when the star wheel 901 rotates, the penicillin bottle 101 can be divided into equal intervals and moved forward to the filling station 501, the plug pressing station 701, until the penicillin bottle 101 enters the bottle receiving disc 801 of the bottle receiving disc assembly 8.

[0022] Example 3

[0023] When filling as a powder medicine, the main function of the powder box assembly 4 is to hold the medicine powder. The medicine powder needs to be placed in the powder box 401 of the powder box assembly 4. The powder box assembly 4 is provided with 1-10 motors. The rotation of the motor can make the powder box 401 rotate clockwise or counterclockwise. The rotation of the powder box 401 can stir the medicine powder in the powder box 401. When the filling needle 502 takes the medicine powder, the powder box 401 is in a static state. After the filling needle 502 takes the medicine powder, the powder box 401 rotates 1-100 times to fully stir the medicine powder, so that the filling needle 502 can well suck the medicine powder into the filling needle 502 when it is inserted into the medicine powder next time.

[0024] After starting the powder dispensing program, the vial 101 is fed by the feeding turntable assembly 2. When the vial 101 rotates to the filling station 501, the filling needle 502 is driven by the motor to rotate above the powder box assembly 4. The filling needle 502 is moved downward into the powder box 401 by the motor drive to take the medicine powder. After taking the medicine powder, the filling needle 502 is raised and rotated to the filling station 501. The filling needle 502 is inserted into the vial 101. The medicine powder is blown into the vial 101 by clean compressed air to complete the filling of the medicine powder.

[0025] Example 4

[0026] When filling as a liquid medicine, start the liquid dispensing program. The vial 101 is fed by the feeding turntable assembly 2. When the vial 101 rotates to the filling station 501, the filling needle 502 is lowered into the vial 101 by the motor drive. The filling needle 502 on the dispensing needle assembly 5 passes through the peristaltic pump 301 to connect the liquid storage device through the hose. The motor of the peristaltic pump 301 rotates to quantitatively dispense the liquid medicine into the vial 101 to complete the dispensing of the liquid medicine. After the dispensing is completed, the filling needle 502 is raised.

[0027] Example 5

[0028] When the vial 101 after filling is conveyed to the capping station 701, the rubber plug vibrating hopper assembly 6 sorts the rubber plugs into a single column and conveys them to the plug suction station 702. The plug assembly 7 is driven by the motor to lower and suck the rubber plugs. The rubber plugs are grabbed by the vacuum suction. After the rubber plugs are grabbed, the plug assembly 7 is rotated to the capping station 701 by the motor drive. The plug assembly 7 drives the rubber plugs to move downward to press the rubber plugs into the vial 101. The capping action is completed. After the capping is completed, the star wheel 901 conveys the vial 101 to the bottle receiving disc 801. Each vial 101 will repeat the filling and capping actions to realize continuous production.
