Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, specifically to an air washing device. Background Technology

[0002] In the field of aseptic drug manufacturing, quality control is particularly critical for two-piece eye drop and spray formulations. The caps and pump heads, as core components that directly contact the medication, must be processed in strict accordance with aseptic manufacturing standards. However, in current production practice, caps and pump heads often lack targeted particle cleaning processes after sterilization. Due to their intricate and complex structure, with numerous gaps, grooves, and corners, particulate impurities can easily be generated and trapped during sterilization or subsequent operations. These potential sources of particulate contamination are highly likely to mix into the medication during product use, potentially causing adverse drug reactions and posing a serious threat to the product's sterility, stability, and safety, thus presenting a significant challenge to drug quality control.

[0003] Patent CN211990049U discloses a pump head clamping dust removal device, which uses a clamping mechanism to clamp the pump head body and an air gun is set above the pump head body. The air gun sprays air to remove dust from the surface of the pump head body. However, this dust removal method cannot clean the side of the pump head body that is in contact with the liquid, resulting in a high risk of contamination. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an air washing device that reduces particle residue and improves product quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An air washing device includes an air washing base, wherein the air washing base is provided with a positioning hole and a limiting mechanism, the bottom of the positioning hole is connected to an exhaust component, the cleaning area of ​​the positioning hole is connected to an air inlet channel for cleaning materials, and the limiting mechanism is used to abut against one side of the material in the positioning hole for limiting.

[0006] As a further improvement to the above technical solution: The positioning hole is a stepped hole. The air washing seat includes a mounting seat and a positioning seat. The positioning seat is detachably mounted on the mounting seat. The larger diameter of the positioning hole is located inside the positioning seat, and the smaller diameter is located inside the mounting seat.

[0007] The air washing base also includes a guide seat, which is detachably mounted on the positioning seat. The guide seat has a guide hole that mates with the positioning hole, and the entrance of the guide hole has an inverted conical guide portion.

[0008] A sealing ring is provided in the positioning hole, and the sealing ring is located between the mounting base and the positioning base.

[0009] The positioning holes are provided in multiple ways, and the multiple positioning holes are arranged at intervals along the length direction of the air washing seat, and each of them is equipped with an air inlet channel.

[0010] The exhaust assembly includes an exhaust chamber and an exhaust pipe. The exhaust chamber is located below each positioning hole and communicates with the positioning hole. The bottom of the exhaust chamber is arranged at an incline, and the exhaust pipe is connected to the lower part of the exhaust chamber.

[0011] The air intake channel is located on the side of the positioning hole and tilts upward toward the pump head. A diaphragm valve is provided on the air intake channel.

[0012] The limiting mechanism includes a limiting rod and a telescopic drive connected to the limiting rod. The limiting rod is inclined downward and passes through the side wall of the positioning hole, and abuts against one side of the material.

[0013] The air washing device also includes an in-situ detection mechanism, which is used to detect whether there is still material in the positioning hole.

[0014] The air washing device also includes a variable pitch material distribution mechanism, an electrostatic elimination mechanism, and a positioning mechanism arranged in sequence, with the air washing base located between the electrostatic elimination mechanism and the positioning mechanism.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Figures 1 to 5An embodiment of the air washing device of this utility model is shown. The air washing device of this embodiment includes an air washing base 1, a positioning hole 2 and a limiting mechanism 3 are provided in the air washing base 1, an exhaust component 4 is connected to the bottom of the positioning hole 2, an air inlet channel 5 for cleaning material 6 is connected to the cleaning area of ​​the positioning hole 2, and the limiting mechanism 3 is used to abut against one side of the material 6 in the positioning hole 2 for limiting.

[0027] In this air washing device, material 6 is positioned within the positioning hole 2 and restrained by a limiting mechanism 3 on one side to prevent displacement during the air washing process. Clean gas enters through the air inlet channel 5 and is blown into the cleaning area within the positioning hole 2 to wash material 6, reducing particle residue and improving product quality. Finally, the washing gas, along with any remaining particles, is discharged from the bottom exhaust assembly 4. The air inlet channel 5 connects to the cleaning area within the positioning hole 2, facilitating cleaning of the contact side of the pump head with the cleaning solution, rather than the surface side, thus reducing contamination of the cleaning solution during assembly.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the positioning hole 2 is a stepped hole. The air washing seat 1 includes a mounting seat 11 and a positioning seat 12. The positioning seat 12 is detachably mounted on the mounting seat 11. The larger diameter of the positioning hole 2 is located inside the positioning seat 12, and the smaller diameter is located inside the mounting seat 11. This facilitates the assembly and disassembly of the positioning seat 12, and the size of the positioning hole 2 on the positioning seat 12 can be changed to accommodate the cleaning of pump heads with different pump body sizes.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the air washing base 1 also includes a guide seat 13, which is detachably mounted on the positioning base 12. The guide seat 13 has a guide hole 14 that mates with the positioning hole 2, and the inlet of the guide hole 14 has an inverted conical guide portion 15. This provides guidance for the material 6 to be placed into the positioning hole 2. The guide seat 13 is detachable, which makes it easy to change the size of the guide hole 14 to accommodate materials 6 of different sizes.

[0030] Furthermore, such as Figure 2 As shown, in this embodiment, a sealing ring 7 is provided inside the positioning hole 2, and the sealing ring 7 is located between the mounting base 11 and the positioning base 12. This improves the sealing performance and reduces the leakage of gas washing gas from the positioning hole 2, thus preventing environmental pollution. Specifically, the pump head is pressed against the sealing ring 7 by the limiting mechanism 3.

[0031] Furthermore, such as Figure 1 As shown, in this embodiment, multiple positioning holes 2 are provided, and the multiple positioning holes 2 are arranged at intervals along the length direction of the air washing base 1, and each is equipped with an air inlet channel 5. Multiple materials 6 can be air washed at one time, improving the air washing efficiency.

[0032] Furthermore, such as Figure 1As shown, in this embodiment, the exhaust assembly 4 includes an exhaust chamber 41 and an exhaust pipe 42. The exhaust chamber 41 is located below and communicates with each positioning hole 2. The bottom of the exhaust chamber 41 is arranged at an angle, and the exhaust pipe 42 is connected to the lower part of the exhaust chamber 41. The gas discharged from each positioning hole 2 is discharged through the exhaust chamber 41 and the exhaust pipe 42. Preferably, when the air washing device needs to be sterilized, the sterilization pressure head is placed in the positioning hole 2 to ensure that the sterilization pressure head is sealed with the sealing ring 7. Steam is introduced into the air inlet channel 5 to sterilize the entire channel. The angled arrangement of the bottom of the exhaust chamber 41 and the connection of the exhaust pipe 42 to the lower part of the exhaust chamber 41 help increase the flow of gas and liquid and avoid residue.

[0033] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the air inlet channel 5 is located on the side of the positioning hole 2 and is inclined upward toward the material 6. A diaphragm valve 51 is provided on the air inlet channel 5. The air inlet channel 5 is inclined upward toward the material 6, which helps to improve cleaning efficiency and reduce cleaning dead angles. The diaphragm valve 51 on the air inlet channel 5 makes it easy to control the opening and closing of the diaphragm valve 51 to achieve cleaning only when there is no material 6, and avoid the compressed air blown in disturbing the airflow.

[0034] Furthermore, such as Figure 4 As shown, in this embodiment, the limiting mechanism 3 includes a limiting rod 31 and a telescopic drive 32 connected to the limiting rod 31. The limiting rod 31 is inclined downwards and passes through the side wall of the positioning hole 2, abutting against one side of the material 6. The telescopic drive 32 drives the limiting rod 31 to tilt and abut against one side of the material 6, which facilitates pressing the material 6 onto the sealing ring 7 to ensure sealing. Each positioning hole 2 is equipped with a limiting mechanism 3.

[0035] Furthermore, such as Figure 1 As shown, in this embodiment, the air washing device also includes an in-situ detection mechanism 8, which is used to detect whether there is still material 6 in the positioning hole 2. The in-situ detection mechanism 8 is used to check whether a piece of material 6 has been grabbed and emptied after washing to avoid collision.

[0036] Furthermore, such as Figure 5 As shown, in this embodiment, the air washing device further includes a variable-pitch dispensing mechanism 91, a static elimination mechanism 92, and a positioning mechanism 93 arranged sequentially. The air washing base 1 is located between the static elimination mechanism 92 and the positioning mechanism 93. The material 6 is divided into a column with a pitch by the variable-pitch dispensing mechanism 91, then the material 6 is picked up by the picking mechanism (not shown in the figure), and the static electricity on the surface of the material 6 is neutralized by the static elimination mechanism 92. Then, air washing is performed on the air washing base 1, and finally, the picking mechanism (not shown in the figure) picks up the material 6 and presses it onto the bottle positioned by the positioning mechanism 93.

[0037] Furthermore, such as Figure 5As shown, in this embodiment, the positioning mechanism 93 includes a first positioning seat 94, a second positioning seat 95 and a first drive 96. The first positioning seat 94 and the second positioning seat 95 are provided with bottle positioning grooves on opposite sides. The first drive 96 drives the second positioning seat 95 to move closer to or away from the first positioning seat 94 to position the bottle. The second positioning seat 95 is positioned on a positioning guide rail (not shown in the figure) for guidance.

[0038] Furthermore, such as Figure 5 As shown, in this embodiment, the variable pitch material distribution mechanism 91 includes a material distribution dial seat 97, a variable pitch seat 98, and a second drive 99. Specifically, the material distribution dial seat 97 is provided with four material distribution dials 103, the variable pitch seat 98 is provided with eight bottle placement slots 100, and the second drive 99 is used to drive the variable pitch seat 98 to move so that the four material distribution dials can distribute material to the eight bottle placement slots.

[0039] Furthermore, such as Figure 5 As shown, in this embodiment, a blocking cylinder 101 is provided at the inlet of the dispensing wheel 99. When there is no bottle on the positioning mechanism 93, the blocking cylinder 101 extends to block the inlet of the dispensing wheel 99, so that no bottle enters the pump head.

[0040] Furthermore, such as Figure 5 As shown, in this embodiment, the variable pitch seat 98 drives the gear to rotate through the second drive 99, thereby driving the rack to move, and in turn driving the variable pitch seat 98 to move. If the gear rack is set below the platform (not shown in the figure), the platform needs to be opened with a long through slot to realize the movement transmission, which increases the risk of the transmission mechanism contaminating the platform. In this embodiment, the gear rack is set above the platform, so it is only necessary to open a clearance hole for the gear shaft on the platform. Then, a cover 101 is provided on the outside of the gear rack to avoid the transmission mechanism from contaminating the platform environment.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
