Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food and medicine packaging equipment and methods, in particular to a blow-filling-seal mold device and a molding method, a continuous blow-filling-seal equipment and a use method. BACKGROUND

[0002] The traditional blow-filling-seal integrated machine is an intermittent equipment, and the production process includes extrusion, molding, filling and punching and other stations. The molding mold receives and cuts the extrusion embryo at the extrusion station, then the molding mold is transferred to the filling station to complete the molding, filling and sealing processes, and finally the product is separated from the waste at the punching station. The production efficiency is low, and the transfer of the embryo is carried out in an open state during the production process, which has a pollution risk to the filling liquid.

[0003] Patent document (CN114835078A) discloses a continuous production blow-filling-seal equipment and its use method, which can continuously complete the extrusion, molding, filling and sealing processes, which is beneficial to improve the production efficiency, and the embryo is in a closed state during the entire production process, avoiding the pollution risk of the external environment to the filling liquid. The use method can ensure that the embryo is always clamped and fixed at least at one place through the cooperation of the upper clamping assembly and the lower clamping assembly during the entire production process, which can effectively avoid the risk of embryo shaking caused by the opening and closing of the bottle head mold and the bottle body mold, and further ensure the uniformity of the product. However, in the scheme, the upper clamping assembly and the bottle head mold act separately, i.e. the bottle head mold is closed, and then the upper clamping assembly clamps the embryo. This way prolongs the cycle of the entire process (the upper clamping assembly needs to wait for the bottle head mold to close before clamping the embryo), which is not conducive to further improving the production efficiency, and on the other hand, the bottle head mold and the upper clamping assembly will generate two impacts on the embryo in succession, which is not conducive to further maintaining the stability of the embryo. Patent document (CN104837603B) discloses an equipment for manufacturing container products from plastic raw materials. This scheme also clamps the embryo after completing the sealing process, so it still has the above-mentioned defects. SUMMARY

[0051] The application will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0052] Example 1

[0053] Figure 1 An embodiment of the blow-filling-seal die device of the application is shown. The blow-filling-seal die device of this embodiment includes a bottle body forming die 5, a sealing die 4 arranged on the upper side of the bottle body forming die 5, an upper clamping component 7 arranged on the upper side of the sealing die 4, and a lower clamping component 6 arranged on the lower side of the upper clamping component 7. The sealing die 4 is provided with a pusher 41 for driving the upper clamping component 7 to move synchronously when the die is closed. The upper clamping component 7 is connected with a reset driving member 73 (such as a commonly used air cylinder, oil cylinder, or electric push rod, etc.).

[0054] The blowing, filling and sealing mold device of the embodiment is provided with a pushing member 41 on the sealing mold 4. When the sealing mold 4 is closed, the pushing member 41 pushes the upper clamping component 7 to clamp the embryo 10 synchronously. After the sealing mold 4 is opened, the reset driving member 73 is used to keep the upper clamping component 7 clamped and reset the upper clamping component 7. Since the upper clamping component 7 and the sealing mold are synchronous, there is no need to wait, so the cycle of the whole cycle process can be shortened, and the impact times on the embryo 10 can be reduced. Further, compared with the active synchronous movement of the upper clamping component 7 and the sealing mold 4 driven by the reset driving member 73 to abut against the embryo 10, the upper clamping component 7 is passively synchronous with the sealing mold 4 under the action of the pushing member 41 to abut against the embryo 10, which is a pure mechanical structure, simpler and lower in cost, without the need for complex synchronous control, and without the problem of control error that is difficult to avoid in synchronous control. As long as the initial installation positions of the upper clamping component 7, the pushing member 41 and the sealing mold 4 are accurate, the position of the upper clamping component 7 when clamping the embryo 10 can be aligned with the position of the sealing mold 4 when closed, so as to avoid the embryo 10 from being skewed upward and downward, which is beneficial to reducing the waste in the left and right directions of the embryo 10.

[0055] When the reset driving member 73 is a pneumatic cylinder, preferably, during the closing process, the rodless cavity of the pneumatic cylinder is inflated while the pushing member 41 pushes the upper clamping component 7 to move, and the piston rod of the pneumatic cylinder is extended, but the inflation speed cannot be too fast to avoid the separation of the upper clamping component 7 and the pushing member 41. The upper clamping component 7 can be inflated immediately after abutting against the embryo 10. After the sealing mold 4 is opened, the upper clamping component 7 can be kept clamped immediately.

[0056] Further, in the embodiment, the pushing member 41 is a push plate. The push plate can have a large contact area with the upper clamping component 7, which is beneficial to the synchronous movement of the upper clamping component 7 as a whole, and the structure is simple and reliable. Of course, in other embodiments, the pushing member 41 can also be a push rod, a push block, etc.

[0057] Embodiment two

[0058] The forming method of the blowing, filling and sealing mold device of the embodiment is as follows:

[0059] S1, bottle body forming: the bottle body forming mold 5 is closed to abut against the embryo 10, and the bottle body is formed after filling;

[0060] S2, bottle head sealing: the sealing mold 4 is closed to abut against the embryo 10 and drive the upper clamping component 7 to move synchronously;

[0061] S3, the bottle body forming die 5 is opened, and then the sealing die 4 is opened; or, the bottle body forming die 5 and the sealing die 4 are synchronously opened;

[0062] S4, the reset driving part 73 drives the upper clamping part 7 to separate from the embryo 10.

[0063] The forming method of the blow-filling-seal die device in the embodiment is that the upper clamping part 7 is driven to synchronously abut against the embryo 10 when the sealing die 4 is closed (for example, the upper clamping part 7 is driven to act by the pushing part 41 on the sealing die 4), and the reset driving part 73 is used to drive the upper clamping part 7 to reset. Since the upper clamping part 7 and the sealing die 4 act synchronously, there is no need to wait, so the cycle period of the whole cycle process can be shortened, and the impact times on the embryo 10 are reduced.

[0064] Embodiment three

[0065] Figures 2 to 8 An embodiment of the continuous blow-filling-seal device is shown. The continuous blow-filling-seal device in the embodiment comprises an extruder 1, an extrusion die head 2 connected with the extruder 1, a filling needle 3 penetrating through the extrusion die head 2, a sealing die 4 located at the lower side of the extrusion die head 2, an upper clamping part 7 located at the upper side of the sealing die 4, a bottle body forming die 5 located below the sealing die 4, and a lower clamping part 6 located at the lower side of the upper clamping part 7. The lower clamping part 6 is arranged on a first lifting mechanism 8, the sealing die 4, the bottle body forming die 5 and the upper clamping part 7 are arranged on a second lifting mechanism 9, the sealing die 4 is provided with a pushing part 41 for driving the upper clamping part 7 to synchronously act when the die is closed, and the upper clamping part 7 is connected with a reset driving part 73. Taking the first lifting mechanism 8 as an example, in the embodiment, the first lifting mechanism 8 comprises a servo motor 81, a ball screw 82 connected with the servo motor 81, and a screw nut 83 arranged on the ball screw 82. The lower clamping part 6 is connected with the screw nut 83. In use, the servo motor 81 drives the ball screw 82 to rotate, the screw nut 83 moves up and down on the ball screw 82, and the lower clamping part 6 moves up and down synchronously with the screw nut 83. The overall structure is simple and reliable, and the movement precision is high. Of course, in other embodiments, the first lifting mechanism 8 can also adopt other forms. The second lifting mechanism 9 can have the same structure as the first lifting mechanism 8, and details are not described herein.

[0066] The continuous blow-filling-sealing device of the embodiment can continuously complete the extrusion, molding, filling and sealing processes, which is conducive to improving the production efficiency, and the embryo 10 is in a closed state during the entire production process, thereby avoiding the pollution risk of the filled liquid by the external environment. The push member 41 is arranged on the sealing mold 4. When the sealing mold 4 is closed, the push member 41 pushes the upper clamping component 7 to synchronously clamp the embryo 10. After the sealing mold 4 is opened, the reset driving member 73 is used to keep the upper clamping component 7 clamped and drive the upper clamping component 7 to reset. Since the upper clamping component and the sealing mold are synchronously actuated, there is no need to wait, so the cycle period of the entire cycle process can be shortened, and the impact frequency on the embryo 10 can be reduced. The upper clamping component 7 cooperates with the lower clamping component 6 to ensure that the embryo 10 is always clamped and fixed at least at one position, which can effectively avoid the shaking of the embryo 10 and the bottle body 20 when the sealing mold 4 and the bottle body molding mold 5 are opened and closed, and further improves the reliability of the device. The sealing mold 4 and the upper clamping component 7 are arranged on the second lifting mechanism 9 to realize synchronous lifting, so as to ensure that the upper side of the sealing mold 4 and the lower side of the upper clamping component 7 are in contact during the entire working process, which is conducive to reducing the waste generated in the upward and downward directions of the embryo 10.

[0067] As a preferred embodiment, the continuous blow-filling-sealing device further comprises a gas supply component (not shown in the figure, such as a fan, a gas supply pipeline, etc.) for providing clean gas to the area where the extrusion die head 2 is located. The gas supply component provides clean oxygen-free gas (such as nitrogen or inert gas, etc.) to the area where the extrusion die head 2 is located, to ensure a sterile and oxygen-free clean environment during the molding, filling and sealing processes.

[0068] Further, in the embodiment, the lower clamping component 6 comprises a clamping plate 61, the inner side of the clamping plate 61 is provided with a bottle body positioning groove 62, the lower side of the bottle body positioning groove 62 is provided with a bottle head positioning groove 63, and the side edges of the bottle body positioning groove 62 and the bottle head positioning groove 63 are provided with cooling channels 64. The lower clamping component 6 can be lifted to the position between the bottle body molds 5 (after the bottle body molds 5 are opened) and clampingly fix the bottle body of the upper bottle body 20 and the bottle head of the lower bottle body 20 under the driving of the first lifting mechanism 8, which can effectively avoid the shaking of the embryo 10 when the sealing mold 4 and the bottle body molding mold 5 are opened and closed. The cooling liquid introduced into the cooling channels 64 of the clamping plate 61 can cool the molded bottle body 20, which is conducive to ensuring the consistency of the bottle body 20.

[0069] Further, in the embodiment, the clamping plate 61 is connected with a first telescopic driving member 65 (for example, a pneumatic cylinder, an electric cylinder, a screw-nut pair, etc.) and a first guide rod 66, and the first guide rod 66 is arranged in a first guide seat 67. The first guide rod 66 and the first guide seat 67 cooperate to provide a guide for the opening and closing movement of the clamping plate 61, which is beneficial to ensure smooth movement and high movement precision.

[0070] Further, in the embodiment, the upper clamping member 7 includes a wedge-shaped clamping block 71, and the wedge-shaped clamping block 71 is connected with a reset driving member 73 through a second guide rod 72, and the second guide rod 72 is arranged in a second guide seat 74. The wedge-shaped clamping block 71 has high mechanical strength, and the thinner side is beneficial to clamping the embryo 10 and reducing material waste, and the thicker side is beneficial to connecting the second guide rod 72. The second guide rod 72 and the second guide seat 74 cooperate to provide a guide for the opening and closing movement of the wedge-shaped clamping block 71, which is beneficial to ensure smooth movement and high movement precision.

[0071] Further, in the embodiment, the needle-filling device 3 includes a needle-filling body 31 and a needle-filling seat 32 for mounting the needle-filling body 31, and a cooling sleeve 33 is arranged between the needle-filling body 31 and the needle-filling seat 32, and a through hole 34 is arranged in the side wall of the lower end of the cooling sleeve 33. Cooling liquid can be introduced into the cooling sleeve 33, flows downward, and then flows out from the through hole 34, and finally flows out of the needle-filling seat 32 from the gap between the cooling sleeve 33 and the needle-filling seat 32. The flowing process can keep the liquid in the needle-filling body 31 warm, and avoid the adverse effects of the high-temperature embryo 10 on the liquid.
