DETAILED DESCRIPTION

[0022] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, this embodiment provides a dual-material capsule filling device, including a capsule machine body 1 and an empty capsule loader 2 connected to the capsule machine body 1, a first material loader 3, a second material loader 4, a first weight metering device 5, and a second weight metering device 6.

[0024] in, Figure 2 : is a schematic diagram of the structure of the capsule machine body in this embodiment, Figure 3 yes Figure 2 The main structure diagram of Figure 4 yes Figure 3 AA cross-sectional structure diagram, as shown in Figure 2-Figure 4 As shown, a plurality of workstations are sequentially arranged in a circle on the capsule machine body 1, and the workstations at least include a first workstation 10 for loading empty capsules, a second workstation 20 for loading a first material, a third workstation 30 for first weight measurement, a fourth workstation 40 for loading a second material, and a fifth workstation 50 for second weight measurement.

[0025] The empty capsule loader 2, the first material loader 3, the second material loader 4, the first weight metering device 5, and the second weight metering device 6 are respectively installed at the first station 10, the second station 20, the third station 30, the fourth station 40 and the fifth station 50.

[0026] This dual-material capsule filling equipment is provided with a first station 10 for empty capsule loading, a second station 20 for first material loading, a third station 30 for first weight measurement, a fourth station 40 for second material loading, and a fifth station 50 for second weight measurement in a circular manner on the capsule machine body 1, and the first material loading machine 3, the second material loading machine 4, the first weight measurement device 5, and the second weight measurement device 6 are installed at the first station 10, the second station 20, the third station 30, the fourth station 40, and the fifth station 50, respectively. The first weight measurement device 5 and the second weight measurement device 6 can be used to perform weighing sampling, thereby improving production efficiency and ensuring product quality. In addition, since the multiple stations are arranged in a circular manner, stations with various purposes can be set according to actual production needs, thereby saving space and meeting usage requirements.

[0027] As an optional embodiment, the second workstation 20 and the fourth workstation 40 are arranged diagonally, and the third workstation 30 and the fifth workstation 50 are arranged diagonally.

[0028] With this arrangement, the two material feeders and the two weight measuring devices can be installed at intervals to avoid interference with each other due to inconvenient installation. At the same time, during the capsule circulation process, operations such as feeding and weight sampling and measuring can be performed without stopping the machine or suspending production, which can improve production efficiency.

[0029] It is understandable that, on the capsule machine body 1, between any two adjacent stations among the first station 10, the second station 20, the third station 30, the fourth station 40 and the fifth station 50, one or more spare stations are also included to facilitate the realization of other functions during the production process.

[0030] As an optional embodiment, the workstations further include a sixth workstation 60 for capsule sorting and capsule cap separation. At least one sixth workstation 60 is provided and is located between the first workstation 10 and the second workstation 20 .

[0031] In this embodiment, a sixth station 60 is provided to facilitate sorting of capsules and separation of the caps of the capsules, so as to prepare for subsequent capsule filling.

[0032] As an optional embodiment, the workstation also includes a cleaning station 70 for cleaning the capsule machine body 1. Two cleaning stations 70 are provided, which are respectively located between the fifth station 50 and the first station 10 and between the third station 30 and the fourth station 40. The cleaning station 70 is used to ensure continuous, stable and smooth production.

[0033] As an optional embodiment, the workstations further include a first capsule cap merging station 80 and a first capsule locking station 90 .

[0034] Among them, the first capsule cap body merging station 80 is arranged between the second station 20 and the third station 30; the first capsule locking station 90 is arranged between the first capsule cap body merging station 80 and the third station 30.

[0035] By providing the first capsule cap merging station 80 and the first capsule locking station 90 , the caps of the capsules filled with the first material can be merged and locked, so that the weight measurement of the first material can be performed by the first weight measuring device 5 .

[0036] As an optional implementation, the workstations further include a second capsule cap merging station 100 and a second capsule locking station 110 .

[0037] The second capsule cap body merging station 100 is disposed between the fourth station 40 and the fifth station 50 , and the second capsule locking station 110 is disposed between the second capsule cap body merging station 100 and the fifth station 50 .

[0038] A second capsule cap merging station 100 and a second capsule locking station 110 are provided to merge and lock the filled capsules to complete product production, so as to facilitate weighing, testing and packaging after subsequent unloading to ensure product quality.

[0039] As an optional implementation, the dual-material capsule filling equipment further includes a metal detection device 7 , and the metal detection device 7 is disposed between the fifth station 50 and the second weight metering device 6 .

[0040] In this embodiment, the fifth station 50 is connected to the inlet of the metal detection device 7 , and the capsule is discharged from the outlet of the metal detection device 7 to the material inlet of the second weight metering device 6 after passing through the metal detection process.

[0041] With such arrangement, after the dual-material capsule is filled with dual materials, it is weighed and metered in the second weight metering device 6 and discharged. Metal detection is performed while discharging the material, which improves production efficiency while ensuring the stability of the content of the active ingredients of the drug, which is of great significance to improving the quality of the drug and ensuring the efficacy.

[0042] As an optional implementation, Figure 5 It is the control principle diagram of this embodiment, such as Figure 5 As shown, a control device 8 is also included. The control device 8 in this embodiment includes a PLC, which is used to achieve automatic and intelligent control through the control device 8.

[0043] The capsule machine body 1 is provided with a first power unit 11 ; the first weight measuring device 5 and the second weight measuring device 6 are both provided with a second power unit 51 , and the first power unit 11 and the second power unit 51 are both electrically connected to the control device 8 .

[0044] Specifically, the first power unit 11 and the second power unit 51 in this embodiment both include servo motors. The first power unit 51 can rotate the capsule machine body 1, thereby driving the capsule to rotate to the corresponding station. The second power unit 52 can push out the capsule.

[0045] The working process of this embodiment is as follows: the empty capsule enters the first station 10 of the capsule machine body 1 through the empty capsule feeder 2, and then the filling work begins. The first material and the second material enter the second station 20 and the fourth station 40 through the first material feeder 3 and the second material feeder 4 respectively. When a weight sampling inspection is required, after the capsule passes through the second station 20, the first material is filled inside the capsule body, and then the capsule is pressed after passing through the first capsule cap body merging station 80 and the first capsule locking station 90 to form a complete finished capsule. At the subsequent third station 30, the third station 30 is connected to the material inlet of the first weight metering device 5, and the second power unit 52 pushes out the finished capsule filled with only the first material, which is weighed and data recorded inside the first weight metering device 5 and then discharged through the material outlet of the first weight metering device 5.

[0046] The test results show that after the first material loading inside the capsule is stable, the first weight sampling and measurement is completed. When the subsequent capsules do not receive the sampling instruction, the servo motors corresponding to the first capsule cap merging station 80 and the first capsule locking station 90 will not start, and the capsule will not be pressed and discharged. The capsule containing the first material inside will run to the fourth station 40 with the machine, where the second material will be fed into the capsule. At this time, there are already two materials inside the capsule. Subsequently, the capsule cap and capsule body are merged at the second capsule cap merging station 100 and the second capsule locking station 110, and discharged at the fifth station 50. The fifth station 50 is connected to the entrance of the metal detection device 7. After the metal detection process, the capsule is discharged from the outlet of the metal detection device 7 to the material inlet of the second weight metering device 6, and weighed and data recorded inside the second weight metering device 6, and then discharged through the material outlet of the second weight metering device 6.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
