Description

Technical Field

[0001] This invention relates to the technical field of food and pharmaceutical packaging machinery, equipment and methods, and in particular to a continuous blow-fill-seal integrated machine and a continuous blow-fill-seal method. Background Technology

[0002] Continuous BFS (Breakout Forming) machines enable a closed, aseptic production process that integrates extrusion, molding, filling, sealing, and demolding in one step. Currently, the market primarily offers rotary multi-mold continuous BFS machines, single-station single-mold machines, and dual-station dual-mold continuous BFS machines. Rotary multi-mold continuous BFS machines offer high throughput but suffer from drawbacks such as complex structure, difficult debugging and operation, high equipment costs, and inflexible product type changes. Single-station single-mold continuous BFS machines offer advantages such as simple structure, ease of operation, low equipment costs, and flexible product type changes, but their low throughput cannot meet demand. Dual-station single-mold continuous BFS machines are developed by adding an extrusion system, filling system, and mold forming system to the single-station single-mold continuous BFS machine. While they inherit some advantages and increase throughput from the single-station continuous BFS machine, the addition of a station increases equipment costs, and the precision debugging and operation of products produced at two stations becomes more difficult.

[0003] Patent document (CN115891106 A) discloses a continuous blow-fill-seal production equipment and its usage method, including a third forming mold, a sealing mold located above the third forming mold, an upper clamping component located above the sealing mold, and a lower clamping component located below the upper clamping component. The sealing mold is equipped with a pusher for synchronously driving the upper clamping component to move when the mold is closed, and the upper clamping component is connected to a reset drive. In its usage method, the third forming mold closes and adheres to the preform, and the bottle is filled after forming; the sealing mold closes and drives the upper clamping component to move synchronously to adhere to the preform; then the sealing mold opens; or, the third forming mold and the sealing mold open synchronously; the reset drive causes the upper clamping component to separate from the preform. However, in this solution, waste is generated for each bottle formed, resulting in high cost, significant waste, and low production efficiency. Summary of the Invention

[0044] Figures 1 to 5An embodiment of the continuous blow-fill-seal integrated machine of the present invention is shown. The continuous blow-fill-seal integrated machine of this embodiment includes a filling device 1, a mold device 2 disposed below the filling device 1, and a feeding mechanism 3 for supplying preforms 5 to the mold device 2. The mold device 2 includes a first lifting mechanism 21, a second lifting mechanism 22, and an upper clamping mechanism 23, a first forming mold 24, a second forming mold 25, a third forming mold 26, and a lower clamping mechanism 27 arranged sequentially from top to bottom.

[0046] Taking bottle tail-up filling as an example, the production process of the continuous blow-fill-seal integrated machine of the present invention is as follows: the feeding mechanism 3 supplies the preform 5 to the mold device 2; the third forming mold 26 closes the preform 5 and forms the first bottle body; the second lifting mechanism 22 drives the upper clamping mechanism 23, the first forming mold 24, the second forming mold 25 and the third forming mold 26 to descend synchronously with the preform 5; the filling device 1 descends to the set position to fill the first bottle body, and resets after filling; the second forming mold 25 closes the preform 5 and forms the bottle tail of the first bottle body and the second bottle body. The second lifting mechanism 22 drives the upper clamping mechanism 23, the first forming mold 24, the second forming mold 25, and the third forming mold 26 to descend synchronously with the preform 5; the filling device 1 descends to the set position to fill the second bottle body, and resets after filling; the first forming mold 24 closes and forms the bottle tail of the second bottle body, and seals the bottle tail of the second bottle body, while the upper clamping mechanism 23 clamps the preform 5, and the second lifting mechanism 22 drives the upper clamping mechanism 23, the first forming mold 24, the second forming mold 25, and the third forming mold 26 to descend synchronously with the preform 5. 5. Simultaneous descent; the third forming mold 26 opens, the first lifting mechanism 21 drives the lower clamping mechanism 27 to rise into the third forming mold 26, and then clamps the first bottle body; the second forming mold 25 and the lower clamping mechanism 27 open, the first lifting mechanism 21 drives the lower clamping mechanism 27 to rise into the second forming mold 25, and then clamps the first bottle body and the second bottle body; the first forming mold 24 opens, the upper clamping mechanism 23 maintains clamping, the first lifting mechanism 21 drives the lower clamping mechanism 27 to descend synchronously with the first bottle body and the second bottle body, the second lifting mechanism... Mechanism 22 drives the upper clamping mechanism 23, the first forming mold 24, the second forming mold 25 and the third forming mold 26 to descend synchronously to the set position; the upper clamping mechanism 23 opens, the second lifting mechanism 22 drives the upper clamping mechanism 23, the first forming mold 24, the second forming mold 25 and the third forming mold 26 to rise to the initial position, the lower clamping mechanism 27 maintains clamping, the first lifting mechanism 21 drives the lower clamping mechanism 27 to descend synchronously with the first bottle body and the second bottle body; steps S2 to S10 are repeated until production is completed or the machine stops due to malfunction.

[0047] This continuous blow-fill-seal machine uses three forming molds and two clamping mechanisms. The upper clamping mechanism 23 clamps once, forming and filling two bottles, generating one waste (the waste is generated by the upper clamping mechanism 23). That is, only two bottles generate one waste, which reduces waste, lowers costs, and improves production efficiency.

[0048] In this embodiment, the first lifting mechanism 21 includes a servo motor, a ball screw connected to the servo motor, and a screw nut mounted on the ball screw. The lower clamping mechanism 27 is connected to the screw nut. During use, the servo motor drives the ball screw to rotate, and the screw nut moves up and down on the ball screw. The lower clamping mechanism 27 moves up and down synchronously with the screw nut. The overall structure is simple, reliable, and has high motion accuracy. Of course, in other embodiments, the first lifting mechanism 21 can also take other forms. The second lifting mechanism 22 can have the same structure as the first lifting mechanism 21, and will not be described further.

[0049] In this embodiment, the first molding die 24 is provided with a pusher 6 for driving the upper clamping mechanism 23 to move synchronously when the die is closed, and the upper clamping mechanism 23 is connected to a reset drive 4.

[0050] A pusher 6 is provided on the first molding die 24. When the first molding die 24 closes, the pusher 6 pushes the upper clamping mechanism 23 to clamp the blank 5 synchronously. After the first molding die 24 opens, the reset drive 4 is used to keep the upper clamping mechanism 23 clamped and to drive the upper clamping mechanism 23 to reset. Since the upper clamping mechanism 23 moves synchronously with the first molding die 24, there is no need to wait, thus shortening the cycle of the entire process and reducing the number of impacts on the blank 5. Furthermore, compared to using the reset drive 4 to drive the upper clamping mechanism 23 to actively move synchronously with the first molding die 24 and come into contact with it, The upper clamping mechanism 23 passively moves synchronously with the first molding mold 24 to abut the blank 5 under the action of the pusher 6. It is a purely mechanical structure, which is simpler and lower in cost. It does not require complex synchronous control and will not have the control error problem that is difficult to avoid with synchronous control. As long as the initial installation positions of the upper clamping mechanism 23, the pusher 6 and the first molding mold 24 are accurate, the position of the upper clamping mechanism 23 when clamping the blank 5 can be aligned vertically with the position of the first molding mold 24 when closing the mold, so as to avoid the blank 5 from tilting vertically and reduce the waste generated in the left and right directions of the blank 5.

[0051] When the reset drive 4 is a cylinder, preferably, during the mold closing process, while the pusher 6 pushes the upper clamping mechanism 23 to move, the rodless chamber of the cylinder is inflated, pushing the piston rod of the cylinder to extend. However, the inflation speed should not be too fast to avoid separation between the upper clamping mechanism 23 and the pusher 6; alternatively, the upper clamping mechanism 23 can be inflated immediately after contacting the blank 5. Subsequently, when the first molding die 24 is opened, the upper clamping mechanism 23 can immediately maintain the clamping state.

[0052] Furthermore, in this embodiment, the pushing member 6 is a push plate. The push plate can have a large contact area with the upper clamping mechanism 23, which is beneficial for the upper clamping mechanism 23 to move synchronously as a whole, and the structure is simple and reliable. Of course, in other embodiments, the pushing member 6 can also be a push rod, push block, etc.

[0053] In this embodiment, the lower clamping mechanism 27 includes a pair of clamping plates 271 and a lower clamping drive mechanism 272 for driving the pair of clamping plates 271 closer and further apart. The inner side of the clamping plates 271 is provided with a bottle body positioning groove 273 and a whole bottle positioning groove 274 that are connected vertically. Driven by the first lifting mechanism 21, the lower clamping mechanism 27 can rise between the pair of molding molds (after the pair of molding molds have been opened) and simultaneously clamp and fix the bottle body between the pair of molding molds, effectively preventing the preform 5 from shaking when the molding molds are opened and closed. The inner side of the clamping plates 271 is also provided with a bottle head or bottle tail positioning groove, which is located below the whole bottle positioning groove 274 and communicates with it. The bottle body positioning groove 273 extends to the top of the clamping plate 271, and the bottle head or bottle tail positioning groove extends to the bottom of the clamping plate 271.

[0054] In this embodiment, cooling channels are provided on the sides of the bottle positioning groove 273 and the whole bottle positioning groove 274. Furthermore, the coolant flowing through the cooling channels in the clamping plate 271 can cool the molded bottle, which helps ensure the consistency of the bottle.

[0055] In this embodiment, the upper clamping mechanism 23 includes a pair of wedge-shaped clamping blocks 231. The wedge-shaped clamping blocks 231 are connected to the reset drive member 4 via a second guide rod 232, which passes through the second guide seat 233. The wedge-shaped clamping blocks 231 offer high mechanical strength; the thinner side facilitates clamping the blank 5, reducing material waste, while the thicker side facilitates connection to the second guide rod 232. The second guide rod 232, in cooperation with the second guide seat 233, provides guidance for the opening and closing action of the wedge-shaped clamping blocks 231, ensuring smooth movement and high motion accuracy.

[0056] In this embodiment, the third molding die 26 includes a pair of third molding templates 261 and a third driving mechanism 262 for driving the pair of third molding templates 261 closer and further apart. The inner side of the third molding templates 261 is provided with a third molding groove 263 for molding the first bottle body. The third driving mechanism 262 is used to drive the pair of third molding templates 261 closer and further apart to realize mold opening and mold closing. The third molding grooves 263 of the pair of third molding templates 261 are arranged opposite to each other. When the mold is closed, the third molding grooves 263 of the pair of third molding templates 261 are assembled to form a cavity for molding the first bottle body.

[0057] In this embodiment, the second molding mold 25 includes a pair of second molding templates 251 and a second driving mechanism 252 for driving the pair of second molding templates 251 closer and further away. The inner side of each second molding template 251 is provided with a second molding groove 253 and a fourth molding groove 254 that are vertically connected. The second molding groove 253 is used to form the second bottle body, and the fourth molding groove 254 is used to form the bottle head or bottle tail of the first bottle body. The second molding templates 251 are used to drive the pair of second molding templates 251 closer and further away, realizing mold opening and closing. The second molding grooves 253 and the fourth molding grooves 254 of the pair of second molding templates 251 are arranged opposite to each other. When the mold is closed, the second molding grooves 253 and the fourth molding grooves 254 of the pair of second molding templates 251 are joined together to form a chamber for forming the second bottle body and a chamber for forming the bottle head or bottle tail of the first bottle body, respectively. The second molding groove 253 is located above the fourth molding groove 254.

[0058] In this embodiment, the first molding die 24 includes a pair of first molding templates 241 and a first driving mechanism 242 for driving the pair of first molding templates 241 closer and further away. The inner side of the first molding templates 241 is provided with a first molding groove 243 for molding the bottle head or bottle tail of the second bottle body. The first driving mechanism 242 is used to drive the pair of first molding templates 241 closer and further away to realize mold opening and mold closing. The first molding grooves 243 of the pair of first molding templates 241 are arranged opposite to each other. When the mold is closed, the first molding grooves 243 of the pair of first molding templates 241 are assembled to form a cavity for molding the bottle head or bottle tail of the second bottle body.

[0072] This continuous blow-fill-seal method uses three forming molds and two clamping mechanisms. The upper clamping mechanism 23 clamps once, forming and filling two bottles, generating one waste (the waste is generated by the upper clamping mechanism 23). That is, only two bottles generate one waste, which reduces waste, lowers costs, and improves production efficiency.

[0073] The first bottle body and the second bottle body are adjacent to each other. During the production process, the first bottle body is located below the second bottle body, which is the bottle body that is formed and filled first.

[0074] In this embodiment, steps S6 and S7 are performed simultaneously. This reduces waiting time and improves production efficiency.
