Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery, and in particular to an inflation device for use in the packaging process of outer barrier bags. Background Technology

[0002] Fully automatic packaging machines are a key piece of equipment widely used in the pharmaceutical industry for the production of drug outer packaging. Their main function is to automatically wrap, seal, and cut tubular roll films.

[0003] As attached Figure 1-2 As shown, when packaging the ampoule body 4 using the fully automatic packaging machine 2, the ampoule body 4 enters the bag maker of the fully automatic packaging machine 2 along the conveying channel 11 in the center of the ampoule conveyor table 1. After the ampoule body 4 is in place, the packaging film, under the traction of the film drive roller in the fully automatic packaging machine 2, is tightly wrapped around the ampoule body 4 by the ironing longitudinal sealing roller and the upper and lower clamping mechanisms to form a cylindrical roll film structure. A stainless steel hollow inflation tube 5 with an inner diameter of 3mm is also provided on the ampoule conveyor table, which is connected to a carbon dioxide gas source or other inert gas source. At the same time as the cylindrical roll film structure is formed, the end of the inflation tube 5 is close to the ampoule body 4 being packaged and located inside the cylindrical roll film structure, thereby filling the cylindrical roll film structure with carbon dioxide gas to replace the air inside the cylindrical roll film and achieve the preset carbon dioxide concentration requirement. Finally, after the longitudinal sealing wheel of the fully automatic packaging machine 2 completes the longitudinal sealing, the cylindrical roll film is conveyed to the transverse sealing mechanism of the fully automatic packaging machine 2 for transverse sealing and cutting, and finally the finished product is output by the ampoule product conveyor 3.

[0004] In the aforementioned production process, because the inflation tube 5 is located directly above and close to the ampoule body 4, friction often occurs during packaging due to direct contact between the inflation tube 5 and the ampoule body 4, causing the ampoule body 4 to deviate from its position within the cylindrical film roll. The displaced ampoule body 4 is easily damaged by the cutter during the subsequent horizontal sealing stage, resulting in ampoule product loss and equipment downtime, impacting production efficiency. Furthermore, the depth to which the inflation tube 5 extends into the cylindrical film affects the amount of air displaced per unit time, thus influencing the concentration of carbon dioxide within the film. However, the position of the inflation tube 5 on the ampoule conveyor is fixed, and it is impossible to maintain the carbon dioxide concentration within the required range under different operating conditions by adjusting its position. Therefore, improvements to the existing inflation device are necessary. Utility Model Content

[0005] To address the problems existing in the prior art, where the inflation tube often comes into contact with the ampoule body during packaging, causing the ampoule body to shift and deviate within the cylindrical roll film, leading to easy damage to the ampoule body by the cutter in subsequent processes, resulting in ampoule product loss and equipment downtime, this utility model aims to provide an inflation device for the packaging process of outer barrier bags. By setting a fixing tube on the ampoule conveyor table to fix the position of the inflation tube, and fixing the inflation tube above the ampoule body but offset from directly above the axis of the ampoule body, the distance between the inflation tube and the ampoule body is maximized without affecting the packaging process, thus preventing the inflation tube from contacting the ampoule body.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An inflation device for an outer barrier bag packaging process is disclosed, used to package ampoule bodies and inflate the packaging bag. The device includes an ampoule conveyor, a fully automatic packaging machine, and an inflation tube. The ampoule bodies are conveyed along the ampoule conveyor to the fully automatic packaging machine, which forms a packaging bag around the ampoule bodies and performs the packaging. The inflation tube extends into the packaging bag and inflates it with gas. A fixed tube is provided on the ampoule conveyor, the length of which is aligned with the conveying direction of the ampoule bodies. The inflation tube can be inserted into and passes through the fixed tube, which is used to fix the position of the inflation tube. The inflation tube is located above the ampoule bodies and offset from directly above the axis of the ampoule bodies.

[0007] The present invention is further configured such that: a conveying channel is provided on the ampoule conveying platform, the conveying channel is used to convey the ampoule body, and the fixing tube is provided on one side of the conveying direction of the conveying channel and located above the conveying channel.

[0008] The present invention is further configured to include an ampoule product conveyor, which is located downstream of the ampoule bottle conveyor. The ampoule bottle body, after being packaged and inflated by the fully automatic packaging machine, is conveyed to the downstream process via the ampoule product conveyor.

[0009] The present invention is further configured such that: a scale is provided on the outer wall of the inflation tube, and the scale, in conjunction with the fixed tube, can be used to display the insertion depth of the inflation tube.

[0010] The present invention is further configured such that the starting scale of the scale is located at the end of the inflation tube.

[0011] The present invention is further configured such that the inner diameter of the fixed tube is adapted to the outer diameter of the inflation tube.

[0012] The present invention is further configured such that the axis of the fixing tube is inclined in the vertical direction, and the vertical height of the end of the fixing tube near the ampoule body being packaged is higher than that of the other end of the fixing tube.

[0013] In summary, the beneficial effects achieved by this utility model are as follows: (1) By setting a fixed tube on the ampoule conveying platform, the position of the inflation tube is fixed, and the inflation tube is fixed above the ampoule body and directly above the axis of the ampoule body, so that the distance between the inflation tube and the ampoule body is maximized, preventing the ampoule body from shifting due to contact between the inflation tube and the ampoule body. (2) The scale on the outer wall of the inflation tube, together with the fixed tube, can accurately display the depth of the inflation tube inserted into the packaging bag. The operator can accurately adjust the insertion depth of the inflation tube by observing the scale, thereby adjusting the concentration of carbon dioxide in the packaging bag, so that the concentration of carbon dioxide gas in the packaging bag is always within the range of process requirements.

For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] As attached Figure 3-5 As shown, an inflation device for the packaging process of an outer barrier bag is used to package the ampoule body 4 and inflate the packaging bag. The device includes an ampoule conveyor 1, a fully automatic packaging machine 2, an ampoule product conveyor 3, and an inflation pipe 5.

[0020] The body of the ampoule 4 is cylindrical.

[0021] A recessed conveying channel 11 is provided in the center of the ampoule conveyor 1, and the ampoule body 4 is located in the conveying channel 11. A chain conveyor mechanism, as in the prior art, is provided below the conveying channel 11. The chain conveyor mechanism can transport the ampoule body 4 along the conveying channel 11 to the fully automatic packaging machine 2 downstream of the ampoule conveyor 1.

[0022] The fully automatic packaging machine 2 is a piece of equipment in the prior art, which can form a cylindrical roll film-shaped packaging bag with a single-sided opening around the ampoule body 4 to package the ampoule body 4.

[0023] The ampoule product conveyor 3 is located downstream of the fully automatic packaging machine 2. It is used to transport the ampoule bottle body 4, which has been packaged and filled by the fully automatic packaging machine 2, to the downstream process of the production line via the ampoule product conveyor 3.

[0024] The inflation tube 5 is a hollow 304 stainless steel tube with an inner diameter of 3mm. One end of it can be inserted into the packaging bag from the opening end for inflation, and the other end is equipped with a flexible tube and connected to a carbon dioxide gas source or other inert gas source required by the process.

[0025] A fixing tube 12 is provided on the ampoule conveyor 1. The inner diameter of the fixing tube 12 is matched with the outer diameter of the inflation tube 5, so the inflation tube 5 can be inserted into and pass through the fixing tube 12. The fixing tube 12 is used to fix the position of the inflation tube 5.

[0026] The length direction of the fixing tube 12 is consistent with the conveying direction of the ampoule body 4, and the fixing tube 12 is located on one side of the conveying direction of the conveying channel 11 and above the conveying channel 11. Therefore, when the inflation tube 5 is inserted into the fixing tube 12, the inflation tube 5 is fixed above the ampoule body 4.

[0027] In this embodiment, the axis of the fixing tube 12 is set horizontally. Due to the cylindrical shape of the ampoule body 4, the height of the bottle body directly above its axis is greater than the height of the bottle body diagonally above it. Therefore, the inflation tube 5 is set at a position offset from directly above the axis of the ampoule body 4 to maintain the maximum gap between it and the ampoule body 4 without changing the height of the inflation tube 5, thus preventing the ampoule body 4 from shifting.

[0028] In some other embodiments, the axis of the fixing tube 12 is inclined in the vertical direction, and the vertical height of one end of the fixing tube 12 near the packaged ampoule body 4 is higher than the other end of the fixing tube 12. Thus, after the inflation tube 5 is inserted into the fixing tube 12, the height of one end of the inflation tube 5 extending into the packaging bag is higher than the other end, and the inclined setting of the inflation tube 5 can further increase the gap between it and the ampoule body 4.

[0029] Specifically, in this embodiment, a scale 51 is provided on the outer wall of the inflation tube 5. The starting scale of the scale 51 is located at the end of the inflation tube 5, that is, at the air outlet of the inflation tube 5. The scale 51, in conjunction with the fixing tube 12, can be used to display the insertion depth of the inflation tube 5, allowing operators to accurately adjust the insertion depth of the inflation tube 5 into the packaging bag according to the scale 51, thereby adjusting the concentration of carbon dioxide in the packaging bag and ensuring that the concentration of carbon dioxide gas in the packaging bag is always within the process requirements.

[0030] The implementation principle of the above embodiments is as follows: During operation, the ampoule body 4 is sequentially conveyed to the fully automatic packaging machine 2 within the conveying channel 11. After the fully automatic packaging machine 2 forms a packaging bag with one open end, the inflation tube 5, maintaining a certain gap with the ampoule body 4, inflates carbon dioxide gas into the packaging bag, completing the inflation process. When it is necessary to adjust the insertion depth of the inflation tube 5, the position of the inflation tube 5 relative to the fixed tube 12 can be precisely adjusted according to the relative position of one end of the fixed tube 12 on the scale 51, thereby ensuring uniform inflation.

[0031] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
