Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, specifically to a multi-mode continuous blow-fill-seal device. Background Technology

[0002] Blow-fill-seal (BFS) technology is an aseptic filling technology widely used in the pharmaceutical and cosmetic industries, especially continuous BFS, which is increasingly used due to its excellent aseptic packaging capabilities and high throughput. Multi-mold continuous BFS uses multiple sets of molds that rotate continuously around a preform to form the container and complete the filling inside the preform. This type of machine is compatible with products with capacities from 0.4 to 20 ml. Existing continuous BFS systems use chain-type molds that operate continuously. During demolding, the ampoule strap is held by the mold in the upper mold-closing section. This has the disadvantage of the ampoule easily sticking to the mold during demolding, causing the ampoule neck to twist and affecting the product's appearance. This phenomenon is more pronounced for ampoules with an inverted design and a capacity of 5 ml or more. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-mold continuous blow-fill-seal device that provides guidance for the feeding of the molding material chain, reduces the shaking and deviation of the material chain during feeding, thereby assisting the material chain to demold, avoiding sticking to the mold, and improving the appearance.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-mold continuous blow-fill-seal device includes a molding die, a preform extrusion assembly above the molding die, a guiding mechanism, and a mounting base for mounting the guiding mechanism. The mounting base is located below the molding die, and the guiding mechanism is used to form a guiding channel through which the formed material chain passes.

[0006] As a further improvement to the above technical solution:

[0007] The guiding mechanism includes a first guide plate and a second guide plate. The guiding channel is located between the first guide plate and the second guide plate. The guiding channel is arranged along the material chain discharge direction and is close to the mold opening point of the forming mold.

[0008] The guiding mechanism also includes a connecting seat, and the first guide plate and the second guide plate are detachably connected to the mounting seat through the connecting seat.

[0009] The connecting seat includes a support plate and a fixing plate. The first guide plate and the second guide plate are detachably mounted on the corresponding support plate. The support plate is movably mounted on the fixing plate. The moving direction is the direction in which the first guide plate and the second guide plate move closer and further away from each other. The fixing plate is detachably connected to the mounting seat.

[0010] The fixed plate is provided with a waist-shaped hole, and the support plate can move within the waist-shaped hole and be locked by the first locking member.

[0011] The mounting base is provided with a slot, and the fixing plate is provided with a locking block at both ends. The locking block slides in the slot, and the locking block is provided with a second locking member for locking with the mounting base.

[0012] The mounting base is equipped with a telescopic drive, and the first guide plate and the second guide plate are respectively connected to the telescopic ends of the corresponding telescopic drive. The telescopic drive is used to drive the corresponding guide plate to move obliquely.

[0013] Both the first guide plate and the second guide plate have a pre-guide slope at the top.

[0014] The height of a single mold of the forming mold is b, the vertical distance from the top of the mold opening to the top of the first guide plate or the second guide plate is a, where b < a < 1.5b, the width of the formed material is d, and the diameter of the guide channel is c, where 0.5mm < cd < 1.5mm.

[0015] Let T1 be the start time of the blow-fill-seal equipment, T2 be the start time of the molding die to start stable operation, and T3 be the time when the guiding mechanism forms the guiding channel. T3 is later than T2 and T1.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The multi-mold continuous blow-fill-seal equipment disclosed in this utility model extrudes a tube preform through a tube preform extrusion assembly and forms it through a molding die. After the material chain is formed, a guiding mechanism forms a guiding channel to guide the formed material chain, reducing the shaking and deviation of the formed material chain during material discharge, thereby assisting the material chain to demold and avoiding adhesion between the material chain and the molding die, which would cause neck twisting and improve the aesthetics of the product.

[0033] Example 1

[0034] Figures 1 to 7 This invention illustrates an embodiment of the multi-mode continuous blow-fill-seal device. The multi-mode continuous blow-fill-seal device of this embodiment includes a molding die 1, a tube preform extrusion assembly 5 above the molding die 1, a guiding mechanism 2, and a mounting seat 4 for mounting the guiding mechanism 2. The mounting seat 4 is located below the molding die 1, and the guiding mechanism 2 is used to form a guiding channel 23 through which the formed material chain 3 passes.

[0035] In this multi-mold continuous blow-fill-seal equipment, the tube preform extrusion assembly 5 extrudes the tube preform and forms it through the forming mold 1. After the material chain 3 is formed, the guiding mechanism 2 forms a guiding channel 23 to guide the formed material chain 3, reducing the shaking and deviation of the formed material chain 3 when it is unloaded, thereby assisting the material chain 3 to demold, avoiding the material chain 3 from sticking to the forming mold 1 and causing neck twisting, and improving the aesthetics of the product.

[0036] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the guiding mechanism 2 includes a first guide plate 21 and a second guide plate 22. The guiding channel 23 is located between the first guide plate 21 and the second guide plate 22. The guiding channel 23 is arranged along the discharge direction of the material chain 3 and is close to the mold opening of the molding die 1. After the material chain 3 is formed, the first guide plate 21 and the second guide plate 22 are in place, forming the guiding channel 23. The guiding channel 23 is arranged along the discharge direction, which helps to restrict the discharge direction of the material chain 3 after discharge. Furthermore, the guiding channel 23 is close to the mold opening of the molding die 1, which further facilitates the demolding of the material chain 3.

[0037] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the guiding mechanism 2 further includes a connecting seat 24, and the first guide plate 21 and the second guide plate 22 are detachably connected to the mounting seat 4 via the connecting seat 24. This facilitates the installation and removal of the first guide plate 21 and the second guide plate 22 after the material chain 3 is formed.

[0038] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the connecting seat 24 includes a support plate 241 and a fixing plate 242. A first guide plate 21 and a second guide plate 22 are detachably mounted on their respective support plates 241. The support plate 241 is movably mounted on the fixing plate 242, with the moving direction being the direction in which the first guide plate 21 and the second guide plate 22 move closer and further apart. The fixing plate 242 is detachably connected to the mounting seat 4. By adjusting the mounting position of the support plate 241 on the fixing plate 242, the first guide plate 21 and the second guide plate 22 can be moved closer or further apart to adjust the width of the guide channel 23, adapting to the guidance of containers of different specifications and improving adaptability. Furthermore, the guide plates and support plates 241, and the fixing plate 242 and mounting seat 4 are all detachably connected, facilitating assembly and disassembly.

[0039] Furthermore, such as Figure 7 As shown, in this embodiment, the fixing plate 242 is provided with a waist-shaped hole 243, and the support plate 241 can move within the waist-shaped hole 243 and be locked by the first locking member 244. By adjusting the locking position of the first locking member 244 within the waist-shaped hole 243, the installation position of the support plate 241 on the fixing plate 242 can be finely adjusted. The structure is simple and the adjustment is convenient.

[0040] Furthermore, such as Figure 4 As shown, in this embodiment, the mounting base 4 is provided with a slot 41, and the fixing plate 242 has locking blocks 245 at both ends. The locking blocks 245 slide in the slot 41, and the locking blocks 245 are provided with a second locking member 246 for locking with the mounting base 4. During installation, the fixing plate 242 is inserted into the slot 41 of the mounting base 4 from one end until the locking blocks 245 at both ends are respectively locked in the slot 41, and then the second locking member 246 locks it to complete the installation. The structure is simple and the installation is convenient. Preferably, the slot 41 is located at the bottom of the mounting base 4, and the second locking member 246 locks at the bottom, which facilitates installation during the operation of the molding die 1.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, both the first guide plate 21 and the second guide plate 22 are provided with pre-guided inclined surfaces 25 at their tops. This facilitates the smooth entry of the forming material chain 3 into the guide channel 23.

[0042] Furthermore, in this embodiment, the height of a single mold of the molding die 1 is b, the vertical distance from the top of the mold of the molding die 1 to the top of the first guide plate 21 or the second guide plate 22 is a, b < a < 1.5b, the width of the formed material is d, and the diameter of the guide channel 23 is c, 0.5mm < cd < 1.5mm. This improves the guiding and limiting effect and the demolding effect of the guide channel 23.

[0043] Furthermore, in this embodiment, the start-up time of the blow-fill-seal equipment is set to T1, the time when the forming mold 1 begins to operate stably is set to T2, and the time when the guiding mechanism 2 forms the guiding channel 23 is set to T3, with T3 being later than T2 and T1. Since the tube blank's melting effect is not yet optimal when the machine is first started, the container cannot be formed at this time. The rotating forming mold 1 brings the tube blank down, and the material chain 3 brought out from the middle of the forming mold 1 is soft at the end, swaying greatly in the left and right directions, and cannot pass normally through the guiding channel 23. Therefore, it is best to wait until the tube blank's melting stabilizes, the forming mold 1 begins vacuum operation, and the container can be formed normally before installing the guiding plate to form the guiding channel 23. Once the guiding plate is installed in place, it does not need to be moved further and can continuously guide the material chain 3.

[0044] Example 2

[0045] Figures 8 to 10 This paper illustrates another embodiment of the multi-mode continuous blow-fill-seal device of this utility model. The multi-mode continuous blow-fill-seal device in this embodiment is largely the same as that in Embodiment 1, except that: in this embodiment, the mounting base 4 is equipped with a telescopic drive 43, and the first guide plate 21 and the second guide plate 22 are respectively connected to the telescopic ends of the corresponding telescopic drive 43. The telescopic drive 43 is used to drive the corresponding guide plate to move obliquely. When the molding mold 1 enters the vacuum forming container state, after the mold chain 3 is formed, after a delay of 10-30 seconds, the telescopic cylinders 43 on both sides extend obliquely, driving the first guide plate 21 and the second guide plate 22 to move into position, forming a guide channel 23 for guidance. Compared with Embodiment 1, this embodiment uses the telescopic drive 43 to drive the guide plate to move into position, eliminating the need for manual installation, saving time and effort. Furthermore, the telescopic drive 43 drives the guide plate to move obliquely, avoiding contact with the molding mold 1 during movement. Specifically, the telescopic drive 43 is obliquely mounted on the mounting base 4 to facilitate the oblique movement of the guide plate.

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.
