Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, and in particular to a soft mist bottle packaging and forming device. Background Technology

[0002] Currently, SMI (soft mist inhaler) is increasingly favored by consumers both domestically and internationally. Soft mist is a combination drug and device inhalation product. The soft mist bottle is mainly used to hold liquid medicine with active ingredients and is the key to whether the liquid medicine can be perfectly released.

[0003] Soft spray bottles are specially designed plastic containers. To increase the strength and stability of soft spray plastic bottles during transportation or use, the filled soft spray plastic bottles need to be placed inside aluminum cans, and then the aluminum can opening is sealed, serving to secure, protect, and provide an auxiliary seal. The aluminum can encasing the soft spray plastic bottle has an open end and a closed end; the inner diameter of the aluminum can is slightly larger than the outer dimensions of the plastic bottle to ensure that the plastic bottle can be easily inserted.

[0004] In the encapsulation process of soft spray plastic bottles, the first step is a tube shrinking process. Currently, the tube shrinking process for soft spray plastic bottles is generally completed in one step. However, for aluminum cans with a wall thickness of less than 0.6mm, the hardness and toughness of the aluminum can are reduced by the shrinking process, making it easy to damage the aluminum can in a single step. In addition, existing encapsulation equipment can only encapsulate one product at a time, resulting in low production efficiency. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1-4As shown, a soft mist bottle packaging and forming device includes a conveying assembly 4 and a tube shrinking assembly 1, an edge-gathering assembly 2, and a neck forming assembly 3 arranged sequentially along the conveying direction of the conveying assembly 4. The tube shrinking assembly 1 includes a tube shrinking die head 14 and a tube shrinking die head 15 arranged sequentially. The tube shrinking die head 14 is used for pre-shrinking the opening of the aluminum can, and the tube shrinking die head 15 is used for shrinking and forming the opening of the aluminum can. Both the tube shrinking die head 14 and the tube shrinking die head 15 have forming cavities for tube shrinking, and the forming cavity in the tube shrinking die head 14 is larger than the forming cavity in the tube shrinking die head 15. The edge-gathering assembly 2 includes a spinning head for spinning and gathering the edge. The neck forming assembly 3 includes a riveting head for forming the neck. There are two tube shrinking dies head 14, two tube shrinking dies head 15, spinning heads, and riveting heads, which can simultaneously complete the packaging and forming of two products, improving production efficiency. The conveying assembly 4 is used for intermittently conveying materials at equal intervals. Furthermore, this utility model employs a secondary tube shrinking process to shrink aluminum cans, which can shrink not only thick-walled aluminum cans but also thin-walled aluminum cans, thus expanding its application range.

[0029] like Figure 1 , 2 As shown, the tube shrinking assembly 1 also includes a tube shrinking support 11, a tube shrinking lowering electric cylinder 12, and a tube shrinking mold base 13. The top of the tube shrinking support 11 is provided with the tube shrinking lowering electric cylinder 12, and the output end of the tube shrinking lowering electric cylinder 12 is provided with the tube shrinking mold base 13. The tube shrinking mold head 14 and the tube shrinking mold head 2 15 are arranged side by side below the tube shrinking mold base 13.

[0030] like Figure 1 , 3 As shown, the edge-finishing assembly 2 also includes an edge-finishing bracket 21 and a spinning lifting module 22. The edge-finishing bracket 21 is provided with two spinning lifting modules 22 arranged in parallel. Each spinning lifting module 22 has a spinning head at its output end, which can drive the spinning head to rise, fall, and rotate. The spinning head is driven to rotate and fall by the spinning lifting module 22 to perform spinning edge-finishing operations on the aluminum can.

[0031] like Figure 3 As shown, the spinning head includes a spinning base 23 and spinning wheels 24. The lower end of the spinning base 23 is U-shaped, and two symmetrically arranged rotating wheels 24 are provided on both sides of the U-shaped part. The spinning wheels 24 are rotatably connected to the spinning base 23, and a spinning forming part 241 is provided on the opposite side of the two spinning wheels 24. The spinning forming part 241 is a groove with a right-angled cross-section. The right-angled part of the groove is connected by a rounded transition, and the lower end of the groove has a slope that gradually slopes outward from top to bottom to facilitate connection with the aluminum can. During spinning, the spinning head descends close to the top of the aluminum can, and then rotates and descends to spin the opening of the top of the aluminum can, causing it to fold inward and wrap the plastic bottle cap.

[0032] like Figure 1 ,4 As shown, the neck forming component 3 also includes a forming bracket 31 and a riveting module 32. The forming bracket 31 is provided with two riveting modules 32 arranged in parallel. Each riveting module 32 has a riveting head at its output end, which can drive the riveting head to rise, fall, and rotate. The riveting head performs neck forming operations on the aluminum can through the riveting module 32.

[0033] like Figure 4 As shown, the riveting head includes a riveting gripper cylinder 33, which has multiple circumferentially arranged grippers. The number of grippers is no less than two; in this embodiment, three grippers are used. Each gripper has a riveting wheel 34, which is vertically oriented. Its outer side has two protruding riveting portions: a first riveting part 341 and a second riveting part 342, arranged from top to bottom. The outer forming surfaces of both the first and second riveting portions 341 and 342 are arc-shaped, with the arc radius of the second riveting portion 342 being larger than that of the first riveting portion 341. During riveting, the first and second riveting portions 341 and 342 create two neck forming grooves of different sizes and depths on the product neck, resulting in better sealing. During sealing, the product moves sequentially to the shrinking tube assembly 1, the edge-trimming assembly 2, and the neck forming assembly 3 to complete pre-shrinking, shrinking, edge trimming, and neck forming, thus achieving product sealing.

[0034] Example 2

[0035] Based on the structure of Example 1, such as Figure 1 , 2 As shown, the conveying assembly 4 includes a conveying guide rail 41, a second transplanting electric cylinder 42, a slide 43, and a drive plate 44. The conveying guide rail 41 is arranged along the tube shrinking assembly 1, the edge-gathering assembly 2, and the neck forming assembly 3. The conveying guide rail 41 has a long conveying groove in the middle, and the two sides of the conveying groove can limit the aluminum can. The second transplanting electric cylinder 42 is located on the front side of the edge-gathering bracket 21, and its output end is provided with a slide 43. The slide 43 is located on the front side of the conveying guide rail 41 and is arranged parallel to the conveying guide rail 41. Furthermore, a slide rail 45 is provided below the slide block 43, and is slidably connected to the slide rail 45 by a transfer electric cylinder 42. Multiple drive connecting cylinders 46 are provided on the top of the slide block 43. A drive connecting plate 47 is provided at the output end of the drive connecting cylinder 46. A drive plate 44 is provided above the drive connecting plate 47. Multiple evenly arranged drive grooves 441 are provided on the side of the drive plate 44 near the conveying guide rail 41. The spacing of the drive grooves 441 is equal to the spacing of the two shrinking die heads 14.

[0036] In addition, such as Figure 2As shown, since the conveying guide rail 41 is relatively long, there are two slides 43, which are connected by a transplanting connecting plate 48 located between the two slides 43. The transplanting connecting plate 48 is connected to the transplanting electric cylinder 42 via a transplanting connecting seat 49 located below it. There are also two drive connecting plates 47, which are arranged one-to-one with the slides 43. The drive connecting plates 47 are slidably connected to the slides 43 via slide rails 2 located at both ends of the top of the slides 43. The slide rails 2 are arranged perpendicularly to the slide rails 1 45.

[0037] Before conveying, the product stands upright on the conveying guide rail 41. The conveying groove has limiting and supporting functions on both sides. During conveying, the drive plate 44 approaches the conveying guide rail 41 via a drive-connected cylinder. The drive groove 441 is located directly above the conveying groove, inserted into the outside of the product, and cooperates with the conveying groove to limit the product's position. Then, the transfer electric cylinder 42 is activated, driving the drive plate 44 and the product inserted into the drive groove 441 to move. The conveying assembly in this embodiment achieves intermittent, equally spaced conveying. The distance between each conveying is B, which is equal to twice the distance between two tooling shrinking mold heads, corresponding to two products being packaged simultaneously. The conveying assembly 4 of this utility model offers better flexibility compared to roller conveyors or belt conveyors, and the use of limiting conveying results in better conveying stability, preventing displacement and tipping during conveying, and ensuring accurate positioning at each packaging position.

[0038] like Figure 1 , 2 As shown, the soft mist bottle packaging and forming device described above also includes a positioning component 5. The positioning component 5 includes multiple positioning cylinders 51. The positioning cylinders 51 are located below the conveying guide rail 41 and are set one-to-one with each working position of the tube shrinking component 1, the edge gathering component 2 and the neck forming component 3. The positioning cylinder 51 is a three-jaw gripper cylinder, and its grippers can extend into the conveying guide rail 41 to center and clamp the product on the conveying guide rail 41.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
