Description

Technical Field

[0001] This application relates to the field of pharmaceutical preparation technology, and in particular to a two-component pharmaceutical powder dispensing machine. Background Technology

[0002] In the pharmaceutical industry, the repackaging of pharmaceutical powders requires the use of repackaging machines to dispense them into different medicine bottles. During repackaging, multiple different types of powders are often mixed. Existing technologies involve the following methods: empty bottles are transported to the repackaging station of the first repackaging system, where the powder in the hopper is dispensed according to a specific quantity via PLC commands, completing the first powder dispensing. The dispensed single-powder product is then transported to the repackaging station of the second repackaging system, where the powder in the hopper is dispensed according to a specific quantity via PLC commands, completing the second powder dispensing. This achieves the dispensing of two different powders in a fixed ratio. Another repackaging method involves first mixing the two raw materials in a mixing device to form a mixture, and then performing a single dispensing.

[0003] Existing filling machines cannot achieve the function of mixing powder proportion filling. During the production process, it is necessary to check the filling amount of each powder dispensing head and the total filling amount. If the filling amount of the powder dispensing head is abnormal, it needs to be adjusted, which is time-consuming and labor-intensive. Moreover, the powder waste will occur during the filling amount adjustment process. Utility Model Content

[0046] To more clearly illustrate the structure of the two-component powder filling machine 10, the following description of the two-component powder filling machine 10 will be provided in conjunction with the accompanying drawings.

[0047] For example, please refer to Figure 1As shown, a two-component pharmaceutical powder filling machine 10 includes a filling mechanism. The filling mechanism includes a first powder injection component, a second powder injection component, and a rotatable filling turntable 200. The filling turntable 200 has multiple filling stations 201. The first and second powder injection components are spaced apart above the filling turntable 200 to inject powder into the filling bottles 20 within different filling stations 201. The multiple filling stations 201 are spaced apart along the circumference of the filling turntable 200. The two-component pharmaceutical powder filling machine 10 can be mounted on a machine base or platform.

[0048] In some embodiments, the two-component powder filling machine 10 includes a bottle inlet mechanism and a bottle outlet mechanism. The bottle inlet mechanism includes a rotatable bottle inlet turntable 100. The bottle inlet turntable 100 is provided with multiple bottle inlet stations 101. The multiple bottle inlet stations 101 are spaced apart along the circumference of the bottle inlet turntable 100. The bottle inlet turntable 100 and the bottle outlet turntable 300 respectively cooperate with the filling turntable 200. When any bottle inlet station 101 is aligned with any filling station 201, the filling bottle 20 in the bottle inlet station 101 can enter the filling station 201. When any bottle outlet station 301 is aligned with any filling station 201, the filling bottle 20 in the filling station 201 can enter the bottle outlet station 301.

[0049] In some embodiments, the two-component powder dispensing machine 10 includes a control mechanism. The bottle inlet mechanism, dispensing mechanism, and bottle outlet mechanism are electrically connected to the control mechanism.

[0050] In some embodiments, the control mechanism is able to control the amount of powder injected by the first powder injection component and the amount of powder injected by the second powder injection component.

[0051] In some embodiments, the control mechanism may be a PLC (Programmable Logic Controller). The control mechanism can be programmed as needed. The control mechanism is not shown in the accompanying drawings.

[0052] In some embodiments, the bottle feeding station 101 is located at the edge of the bottle feeding turntable 100, and the bottle feeding station 101 is a semi-cylindrical groove.

[0053] The dispensing station 201 is located at the edge of the dispensing turntable 200, and the dispensing station 201 is a semi-cylindrical tank.

[0054] Bottle outlet station 301 is located at the edge of bottle outlet turntable 300, and bottle outlet station 301 is a semi-cylindrical tank.

[0055] The dimensions of the bottle inlet station 101, the dispensing station 201, and the bottle outlet station 301 are the same.

[0056] In some embodiments, the diameter of the dispensing turntable 200 is larger than the diameter of the inlet turntable 100 or the outlet turntable 300.

[0057] In some embodiments, the number of dispensing stations 201 on the dispensing turntable 200 is greater than the number of inlet stations 101 or outlet stations 301 on the bottle inlet turntable 100.

[0058] In some embodiments, the diameter of the inlet turntable 100 is equal to the diameter of the outlet turntable 300.

[0059] In some embodiments, the number of bottle inlet stations 101 of the bottle inlet turntable 100 is equal to the number of bottle outlet stations 301.

[0060] For example, see one example. Figure 1 , Figure 2 As shown, the bottle inlet turntable 100 has 12 inlet stations 101, the bottle outlet turntable 300 has 12 outlet stations 301, and the dispensing turntable 200 has 24 dispensing stations 201. It is easy to understand that in other examples, the number of inlet stations 101 on the bottle inlet turntable 100, the number of outlet stations 301 on the bottle outlet turntable 300, and the number of dispensing stations 201 on the dispensing turntable 200 could be other corresponding matching numbers.

[0061] In some embodiments, the two-component powder dispensing machine 10 also includes auxiliary components, see [link to relevant documentation]. Figure 2 As shown, the auxiliary components include a first limiting baffle 401 and a second limiting baffle 403. The first limiting baffle 401 is curved and arc-shaped. The first limiting baffle 401 is sleeved on the dispensing turntable 200, and there is a gap between the first limiting baffle 401 and the dispensing turntable 200 that can accommodate the dispensing bottle 20. One end of the first limiting baffle 401 extends onto the bottle inlet turntable 100 to block the dispensing bottle 20 in the bottle inlet station 101 into the dispensing station 201. The other end of the first limiting baffle 403 extends to... On the bottle dispensing turntable 300; the second limiting baffle 403 includes a first tip 4031 and a second tip 4032. The second limiting baffle 403 is located between the bottle inlet turntable 100 and the bottle dispensing turntable 300. The first tip 4031 extends into the gap between the bottle inlet turntable 100 and the dispensing turntable 200, and the second tip 4032 extends into the gap between the bottle dispensing turntable 300 and the dispensing turntable 200. The second tip 4032 is used to block the dispensing bottle 20 in the dispensing station 201 from entering the bottle dispensing station 301.

[0062] In some embodiments, the side of the second limiting baffle 403 near the dispensing turntable 200 is curved, and the curvature of the side of the second limiting baffle 403 near the dispensing turntable 200 is the same as the curvature of the dispensing turntable 200. There is a certain gap between the side of the second limiting baffle 403 near the dispensing turntable 200 and the dispensing turntable 200 to ensure that the dispensing turntable 200 can rotate.

[0063] It should be noted that, see Figure 2 As shown, the first tip 4031 extends to the gap between the bottle inlet turntable 100 and the dispensing turntable 200, but does not exceed the tangent point between them. Preferably, the first tip 4031 extends to the gap between the bottle inlet turntable 100 and the dispensing turntable 200, not exceeding the first dispensing station 201. Figure 2 (The position of N1 in the middle).

[0064] See Figure 2 As shown, the second tip 4032 extends to the gap between the bottle dispensing turntable 300 and the dispensing turntable 200, but does not exceed the tangent point between them. Preferably, the second tip 4032 extends to the gap between the bottle dispensing turntable 300 and the dispensing turntable 200 no more than the 20th dispensing station 201. Figure 2 (The location of N20).

[0065] In some of these embodiments, see Figure 2 As shown, the first tip 4031 and the second tip 4032 have an inner recess 4033 on the side away from the dispensing turntable 200. The inner recess 4033 is used to avoid the bottle inlet turntable 100 and the bottle outlet turntable 300.

[0066] In some embodiments, the auxiliary components further include positioning wheels 402 and elastic elements. Positioning wheels 402 are respectively provided at the dispensing stations 201 corresponding to the first and second powder injection components. The positioning wheels 402 are connected to the elastic elements mounted on the base or machine platform. The positioning wheels 402 cooperate with the elastic elements to position the dispensing bottles 20 within the dispensing station 201. When the dispensing bottle 20 enters the corresponding dispensing station 201, the bottle 20 squeezes the positioning wheel 402, and the positioning wheel 402 is fixed within the dispensing station 201 by the action of the elastic elements, ensuring that it does not deviate during powder injection and improving powder injection accuracy.

[0067] It is easy to understand that in some other embodiments, an adsorption mechanism is provided in the bottle inlet station 101, the dispensing station 201, and the bottle outlet station 301. The adsorption mechanism is used to adsorb and fix the dispensing bottles 20 in the corresponding bottle inlet station 101, dispensing station 201, or bottle outlet station 301, and the adsorption mechanism is electrically connected to the control mechanism.

[0068] In some embodiments, the adsorption mechanism includes a nozzle capable of being connected to an external negative pressure generating device. When negative pressure is generated, the nozzle adsorbs onto the outer wall of the dispensing bottle 20 to secure it. The nozzle is not shown in the accompanying drawings.

[0069] In some embodiments, the inner walls of the bottle inlet station 101, the dispensing station 201, and the bottle outlet station 301 are respectively provided with adsorption holes. The adsorption holes can be connected to an external negative pressure generating device, and when negative pressure is generated, the adsorption holes can adsorb the outer wall of the dispensing bottle 20 to fix the dispensing bottle 20. The adsorption holes are not shown in the accompanying drawings.

[0070] In some embodiments, the first powder injection component and the second powder injection component are used for injecting different powders.

The first powder-dispensing mechanism is not shown in the accompanying drawings.

[0073] In some embodiments, the first powder injection mechanism can be one or more of a drive pump and a feed screw. The working principle of the feed screw is mainly to generate thrust through rotation, causing the material to move forward along the screw. The design of the screw (such as pitch, depth, length, and shape) has a significant impact on the material conveying efficiency, mixing effect, and heating uniformity. The screw pitch, depth, length, and shape can be set according to actual needs.

[0074] In some embodiments, the second powder dispensing component includes a second powder dispensing head 230 and a second powder dispensing mechanism. The second powder dispensing mechanism is capable of driving the powder through the second powder dispensing head 230 into the dispensing bottle 20, and the second powder dispensing mechanism is electrically connected to a control mechanism. The second powder dispensing mechanism is not shown in the accompanying drawings.

[0075] In some embodiments, the second powder injection mechanism may be one or more of a drive pump and a feed screw.

[0076] In some embodiments, when dispensing single powders, either the first powder-filling component or the second powder-filling portion may be used.

[0077] The number of the first powder injection components is one or more, and there are nM dispensing stations 201 between adjacent first powder injection components, where n is an integer and n≥0, M is the number of the first powder injection components, and the dispensing turntable 200 rotates M dispensing stations 201 at a time.

[0078] And / or, the number of the second powder injection components is one or more, and there are nM dispensing stations 201 between adjacent second powder injection components, where n is an integer and n≥0, M is the number of the second powder injection components, and the dispensing turntable 200 rotates M dispensing stations 201 at a time.

[0079] Preferably, there are two first powder injection components, and adjacent first powder injection components are separated by nM dispensing stations 201, where n is an integer and n≥0, and M is the number of first powder injection components, M≥2. When the dispensing turntable 200 is stationary, adjacent first powder injection components correspond to any two dispensing stations 201 that are separated by a certain number of intervals. For example, adjacent first powder injection components are separated by 0, 2, 4, or other dispensing stations 201.

[0080] Preferably, there are two second powder-filling components, and adjacent second powder-filling components are separated by nM dispensing stations 201, where n is an integer and n≥0, and M is the number of second powder-filling components, M≥2. When the dispensing turntable 200 is stationary, adjacent second powder-filling components correspond to any two dispensing stations 201 that are separated by a certain number of spaces. For example, adjacent second powder-filling components are separated by 0, 2, 3, 4, 6, etc., dispensing stations 201. Preferably, when mixing powder, the number of second powder-filling components is equal to the number of first powder-filling components.

[0081] In some embodiments, during powder mixing and dispensing, the control mechanism can control the dispensing turntable 200 to rotate M dispensing stations 201 per rotation, where M is the number of first powder-filling components or M is the number of second powder-filling components, and the number of first powder-filling components and M are equal. There are multiple first powder-filling components, with nM dispensing stations 201 between adjacent first powder-filling components, where n is an integer and n≥0. When the dispensing turntable 200 is stationary, adjacent first powder-filling components correspond to any nM dispensing stations 201 apart. Similarly, there are multiple second powder-filling components, with nM dispensing stations 201 between adjacent second powder-filling components, where n is an integer and n≥0. When the dispensing turntable 200 is stationary, adjacent second powder-filling components correspond to any nM dispensing stations 201 apart. The adjacent first powder injection component and the second powder injection component are separated by n dispensing stations 201, where n is an integer and n≥0.

[0082] For example, in one specific embodiment, the control mechanism can control the dispensing turntable 200 to rotate two dispensing stations 201 per rotation. There are two first powder-filling components, with two dispensing stations 201 between adjacent first powder-filling components. When the dispensing turntable 200 is stationary, adjacent first powder-filling components correspond to a distance of two dispensing stations 201. There are also two second powder-filling components, with two dispensing stations 201 between adjacent second powder-filling components. When the dispensing turntable 200 is stationary, adjacent second powder-filling components correspond to a distance of two dispensing stations 201. The nearest adjacent first powder-filling component and second powder-filling component are separated by an even number of dispensing stations 201, such as two, four, or six.

[0085] Preferably, in some embodiments, there are multiple detection mechanisms. Detection mechanisms are respectively provided at the bottle inlet station 101, the dispensing station 201, and the bottle outlet station 301.

When the detection mechanism detects the dispensing bottle 20, the control mechanism controls the first powder injection component or the second powder injection component to inject powder.

[0087] In some embodiments, the detection mechanism can be a sensor, such as a weight sensor, photoelectric sensor, or position sensor.

[0088] For example, see one example. Figure 1 , Figure 2As shown, the bottle inlet turntable 100 has 12 bottle inlet stations 101, the bottle outlet turntable 300 has 12 bottle outlet stations 301, and the dispensing turntable 200 has 24 dispensing stations 201. The dispensing station 201 on the dispensing turntable 200 that aligns with the bottle inlet stations 101 is defined as the first dispensing station 201. Figure 2 (Illustrated as position N1), the fourth and seventh sub-packaging stations 201 are each equipped with a first powder injection component, and the fourteenth and seventeenth sub-packaging stations 201 are each equipped with a second powder injection component. The twentieth sub-packaging station 201 ( Figure 2 The position (indicated by N20) can be aligned with the bottle outlet station 301. It should be noted that the station numbers mentioned above are based on... Figure 2 The fixed angle shown is defined. That is, there are two dispensing stations 201 spaced apart between the first powder injection components on the dispensing turntable 200, and two dispensing stations 201 spaced apart between the second powder injection components. The dispensing stations 201 spaced apart between adjacent first and second powder injection components can be set as needed. In this application, the regularly distributed first and second powder injection components facilitate powder injection control.

[0089] In some embodiments, the bottle feeding mechanism further includes a bottle feeding drive component. The bottle feeding drive component is connected to the bottle feeding turntable 100 and electrically connected to the control mechanism. The bottle feeding drive component drives the bottle feeding turntable 100 to rotate at a preset speed. The bottle feeding drive component may be a rotary motor.

[0090] In some embodiments, the bottle dispensing mechanism further includes a bottle dispensing drive component. The bottle dispensing drive component is connected to the bottle dispensing turntable 300 and electrically connected to the control mechanism. The bottle dispensing drive component drives the bottle dispensing turntable 300 to rotate at a preset speed. The bottle dispensing drive component may be a rotary motor.

[0091] In some embodiments, preferably, the bottle inlet drive component and the bottle outlet drive component can be omitted. The bottle inlet turntable 100, the bottle outlet turntable 300, and the dispensing turntable 200 move synchronously through a conveying mechanism. The bottle inlet turntable 100, the bottle outlet turntable 300, and the dispensing turntable 200 are connected to a cam divider by the conveying mechanism, so that the cam divider drives the movement of the bottle inlet turntable 100, the bottle outlet turntable 300, and the dispensing turntable 200.

[0092] In some embodiments, the dispensing mechanism further includes a cam divider. The cam divider is connected to the dispensing turntable 200 and electrically connected to the control mechanism. The cam divider drives the dispensing turntable 200 to rotate M dispensing stations 201 per cycle, where n is an integer and n≥1, M≥2. In this application, the cam divider contains 12 cam rollers. The motor rotation drives the input shaft of the cam divider, which in turn drives the 12 cam rollers to rotate the output shaft 12 times. The output shaft drives the bottle-separating star wheel to rotate. This achieves the cam divider driving the dispensing turntable 200 to rotate M dispensing stations 201 per cycle.

[0093] An embodiment of this application also provides a method for packaging two-component pharmaceutical powder.

[0094] It should be noted that, unless otherwise stated, the reaction steps may be performed in the order described herein or not. For example, other steps may be included between reaction steps, and the order of reaction steps may be appropriately interchanged. This is something that those skilled in the art can determine based on conventional knowledge and experience. Preferably, the reaction methods described herein are performed sequentially.

[0095] A method for dispensing two-component pharmaceutical powder, using the aforementioned two-component pharmaceutical powder dispensing machine, includes the following steps:

[0096] When dispensing single powders: Load the dispensing bottles 20 one by one into each dispensing station 201;

[0097] When the dispensing bottle 20 in the dispensing station 201 rotates to the position below the first powder injection component or the second powder injection component, the first powder injection component or the second powder injection component is controlled to inject powder according to the preset powder injection amount, and so on, until the dispensing bottle 20 that needs to be injected is injected with powder respectively.

[0098] And / or, when mixing and dispensing powder: load the dispensing bottles 20 one by one into each dispensing station 201;

[0099] When the dispensing bottle 20 in the dispensing station 201 rotates to a position below the first powder injection component, the first powder injection component is controlled to inject powder according to a preset powder injection amount. This process continues until each dispensing bottle 20 requiring powder injection has been injected by the first powder injection component. When the dispensing bottle 20 in the dispensing station 201 rotates to a position below the second powder injection component, the second powder injection component is controlled to inject powder according to a preset powder injection amount. This process continues until each dispensing bottle 20 requiring powder injection has been injected.

[0100] Furthermore, a method for dispensing two-component pharmaceutical powder, using the aforementioned two-component pharmaceutical powder dispensing machine 10, includes the following steps:

[0101] When packaging individual powders:

[0102] The dispensing bottles 20 are loaded one by one into each of the bottle feeding stations 101 of the bottle feeding turntable 100, and the control mechanism controls the rotation of the bottle feeding turntable 100.

[0103] When the inlet station 101 with the dispensing bottle 20 on the inlet turntable 100 rotates to align with one of the dispensing stations 201 on the dispensing turntable 200, the inlet station 101 releases the dispensing bottle 20 and the dispensing station 201 fixes the dispensing bottle 20. This process is repeated to allow the dispensing bottles 20 in each inlet station 101 on the inlet turntable 100 to enter each dispensing station 201 respectively.

[0104] When the dispensing bottle 20 in the dispensing station 201 rotates to the position below the first powder injection component or the second powder injection component, the control mechanism controls one of the first powder injection components or the second powder injection component to inject powder according to the preset powder injection amount, and so on, until the dispensing bottle 20 that needs to be injected is injected with powder.

[0105] The control mechanism controls the dispensing turntable 200 to rotate until the dispensing station 201 with the dispensing bottle 20 is aligned with the bottle outlet station 301 of the bottle outlet turntable 300. The dispensing station 201 releases the dispensing bottle 20 and the bottle outlet station 301 fixes the dispensing bottle 20, and so on.

[0106] In some embodiments, two first powder-filling components are provided, with 2n dispensing stations 201 spaced apart between adjacent first powder-filling components, where n is an integer and n≥0. The dispensing turntable 200 rotates two dispensing stations 201 per rotation. The control mechanism can control the dispensing turntable 200 to rotate 2n dispensing stations 201 per rotation, where n is an integer and n≥1. For example, the control mechanism can control the dispensing turntable 200 to rotate two dispensing stations 201 per rotation. In this case, the two first powder-filling components can dispense powder simultaneously per rotation. Similarly, two second powder-filling components can be provided, and the two second powder-filling components dispense powder according to the above rules. It should be noted that during single powder dispensing, only one of the first and second powder-filling components operates.

[0107] When mixing and packaging powders:

[0108] The dispensing bottles 20 are loaded one by one into each of the bottle feeding stations 101 of the bottle feeding turntable 100, and the control mechanism controls the rotation of the bottle feeding turntable 100.

[0109] When the inlet station 101 with the dispensing bottle 20 on the inlet turntable 100 rotates to align with one of the dispensing stations 201 on the dispensing turntable 200, the inlet station 101 releases the dispensing bottle 20 and the dispensing station 201 fixes the dispensing bottle 20. This process is repeated to allow the dispensing bottles 20 in each inlet station 101 on the inlet turntable 100 to enter each dispensing station 201 respectively.

[0110] When the dispensing bottle 20 in the dispensing station 201 rotates to the position below the first powder injection component, the control mechanism controls the first powder injection component to inject powder according to the preset powder injection amount, and so on, until the dispensing bottles 20 that need to be injected with powder have been injected with powder by the first powder injection component; when the dispensing bottle 20 that has been injected with powder in the dispensing station 201 rotates to the position below the second powder injection component, the control mechanism controls the second powder injection component to inject powder according to the preset powder injection amount, and so on, until the dispensing bottles 20 that need to be injected with powder have been injected with powder.

[0111] The control mechanism controls the dispensing turntable 200 to rotate until the dispensing station 201 with the dispensing bottle 20 is aligned with the bottle outlet station 301 of the bottle outlet turntable 300. The dispensing station 201 releases the dispensing bottle 20 and the bottle outlet station 301 fixes the dispensing bottle 20, and so on.

[0112] In some embodiments, the following steps are further included: when mixing and dispensing powder, the number of first powder-filling components and the number of second powder-filling components are equal. Adjacent first powder-filling components are spaced apart by nM dispensing stations 201, where n is an integer and n≥0, M≥2, and M is the number of first powder-filling components; adjacent second powder-filling components are spaced apart by nM dispensing stations 201, where n is an integer and n≥0, M≥2, and M is the number of second powder-filling components; the closest adjacent first powder-filling component and second powder-filling component are spaced apart by n dispensing stations 201, where n is an integer and n≥0. When the first dispensing bottle 20 in the dispensing station 201 rotates to below the first powder injection component, the first powder injection component is controlled to inject powder according to a preset powder injection amount. The dispensing turntable 200 is controlled to rotate M dispensing stations 201 each time, where n is an integer and n≥1, so that the first dispensing bottle 20 rotates to the (n+1)th dispensing station 201, until the nth dispensing bottle 20 that needs powder injection passes through the first first powder injection component and the (n+1)th dispensing bottle 20 passes through the second first powder injection component. The first powder injection component injects powder, and so on; when the first dispensing bottle 20 after powder injection in the dispensing station 201 rotates to below the first second powder injection component, the second powder injection component is controlled to inject powder according to the preset powder injection amount, so that the first dispensing bottle 20 rotates to the (n+1)th dispensing station 201, until the nth dispensing bottle 20 that needs powder injection is injected by the first second powder injection component, the (n+1)th dispensing bottle 20 is injected by the second second powder injection component, and so on.

[0113] For example, in some embodiments, the number of first powder-injecting components and the number of second powder-injecting components are each one, and there are n dispensing stations 201 between adjacent first and second powder-injecting components, where n≥0. The control mechanism can control the dispensing turntable 200 to rotate one dispensing station 201 per rotation. That is, the first powder-injecting component dispenses a first type of powder into different dispensing bottles 20, and the dispensing bottles 20 after being dispensed by the first powder-injecting component will enter the second powder-injecting component to dispense a second type of powder, thus completing the powder mixing.

[0114] For example, in some embodiments, the number of first powder-filling components and the number of second powder-filling components are equal, and the number of first powder-filling components and the number of second powder-filling components are each two. Adjacent first powder-filling components are spaced nM dispensing stations 201 apart, where n is an integer and n≥0, M≥2, and M is the number of first powder-filling components. When the dispensing turntable 200 is stationary, adjacent first powder-filling components correspond to any nM dispensing stations 201 apart. The control mechanism can control the dispensing turntable 200 to rotate M dispensing stations 201 per rotation, whereby each rotation of the dispensing turntable 200 enables simultaneous powder filling by two first powder-filling components. Similarly, adjacent second powder-filling components are spaced nM dispensing stations 201 apart, where n is an integer and n≥0, M≥2, and M is the number of second powder-filling components. When the dispensing turntable 200 is stationary, adjacent second powder-filling components correspond to any nM dispensing stations 201 apart. At this time, the adjacent first powder injection component and second powder injection component are spaced n times apart by the dispensing stations 201. It should be noted that during powder mixing and injection, the first powder injection component and the second powder injection component work synchronously. When the dispensing turntable 200 is fully loaded with dispensing bottles 20, the first powder injection component and the second powder injection component can inject powder simultaneously. The two first powder injection components do not interfere with each other during injection; that is, the two first powder injection components inject the first type of powder into different dispensing bottles 20 respectively. After the first powder injection component injects powder, the dispensing bottle 20 will enter the second powder injection component for the injection of the second type of powder, thus completing the powder mixing and improving the powder injection efficiency.

[0115] For example, in a specific example, the bottle inlet turntable 100 of the aforementioned two-component powder filling machine 10 has 12 inlet stations 101, the bottle outlet turntable 300 has 12 outlet stations 301, and the filling turntable 200 has 24 filling stations 201. The filling station 201 on the filling turntable 200 that aligns with the bottle inlet station 101 is defined as the first filling station 201. The fourth and seventh filling stations 201 are each equipped with a first powder injection component, and the fourteenth and seventeenth filling stations 201 are each equipped with a second powder injection component. The twenty-first filling station 201 can align with the bottle outlet station 301.

[0116] In summary, the aforementioned two-component powder dispensing machine 10 has a simple structure, no special parts design, and fast processing. It can be used for single-powder dispensing as well as mixed powder dispensing. It has high dispensing efficiency, and different powders do not affect each other during mixing. It can also control the amount of powder dispensed for different powders individually.
