Description

Technical Field

[0001] This utility model relates to the field of filling equipment, and more specifically, to a lifting aseptic filling module and filling machine. Background Technology

[0002] In traditional filling machines, the filling pipes need to penetrate deep into the bottles for filling. However, when the bottles are fully filled, the filling pipes inevitably come into direct contact with the liquid inside. This contact method poses a significant risk. Because the filling pipes are reused between different bottles, even with routine cleaning, it is difficult to completely eliminate residual substances, thus failing to fundamentally ensure that every bottle of liquid remains pure and uncontaminated. This situation clearly cannot meet the increasingly stringent requirements for product quality and urgently needs improvement and optimization. Utility Model Content

[0003] In view of this, the present invention provides a lifting aseptic filling module. When the bottle is empty and the lifting power unit does not contact the lifting platform, the filling pipe partially extends into the bottle, allowing the liquid to be poured directly into the bottom of the bottle, preventing splashing and residue, and improving filling accuracy and hygiene. When the bottle is full and the lifting power unit does not contact the lifting platform, gravity forces the lifting platform to descend, causing the filling pipe to extend completely outside the bottle, isolating the filling pipe from contact with the liquid, and ensuring the purity of the liquid.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A lifting aseptic filling module, positioned between a front conveyor belt and a rear conveyor belt, includes a base, a lifting platform movably connected to the base via a spring and used to support bottles, a lifting power unit for raising the lifting platform, a filling pipe for filling liquid into the bottles, and a filling device connected to the filling pipe. The lifting power unit is located below the lifting platform, and the lifting platform can be at the same height as the front and rear conveyor belts under the action of the lifting power unit. When the bottles are unloaded and the lifting power unit is not in contact with the lifting platform, the filling pipe partially extends into the bottles; when the bottles are in or near-unloaded and the lifting power unit is not in contact with the lifting platform, the filling pipe extends completely outside the bottles.

[0006] When the bottle is in an empty state and the lifting power unit is not in contact with the lifting platform, the liquid filling pipeline partially extends into the bottle. This design can accurately position the liquid filling pipeline in the appropriate position inside the bottle before the filling starts, ensuring that the liquid can be directly injected into the bottom of the bottle, avoiding splashing or residue of the liquid near the bottle mouth, effectively improving the accuracy and hygiene of the filling. At the same time, when the bottle is in or near a full state and the lifting power unit is not in contact with the lifting platform, the gravity on the lifting platform increases, and the greater gravity forces the lifting platform to descend, and the liquid filling pipeline is fully extended outside the bottle, avoiding contact between the outer surface of the liquid filling pipeline and the liquid, ensuring the purity of the filled liquid.

[0007] Preferably, the base is connected with a first guard plate and a second guard plate on both sides, and the first guard plate and the second guard plate extend upwards above the highest point of the lifting platform stroke.

[0008] The safety and protection of the entire lifting sterile filling module are enhanced. During the operation of the equipment, the first guard plate and the second guard plate can block the accidental falling of foreign matter into the equipment, avoid interference with the normal operation of the filling module, and prevent mechanical failure or product contamination caused by foreign matter. Especially in some complex factory workshops, there may be dust, debris and other sundries around, and the presence of the guard plate can effectively resist these potential threats and ensure that the filling module always works in a relatively clean and safe environment. For the operator, the guard plate extending upwards above the highest point of the lifting platform stroke provides a reliable protective barrier. During the lifting platform moving up and down, it can prevent the operator from accidentally touching the moving parts and avoid personal injury caused by accidental contact. This not only ensures the safety of employees, but also meets the relevant safety production standards and requirements, reducing the safety risks of enterprises in the production process. From the overall structure, the setting of the first guard plate and the second guard plate enhances the integrity and stability of the equipment. They are closely connected with the base, like a part of the frame structure, providing additional support and reinforcement for the entire filling module. During the operation of the equipment, it can better resist vibration and external impact, reduce the influence of equipment shaking on filling accuracy, and help maintain the stability and consistency of filling operations.

[0009] Preferably, the lifting platform is provided with a sliding block on both sides, and the first guard plate and the second guard plate are provided with a sliding rail in sliding connection with the sliding block.

[0010] The cooperation of the sliding block and the sliding rail provides accurate guidance for the up-and-down movement of the lifting platform. When the lifting platform rises or falls, the sliding block slides smoothly along the sliding rail, ensuring that the lifting platform always moves along the predetermined vertical direction, greatly improving the straightness and stability of the lifting platform movement.

[0011] Preferably, the bottom of the lifting platform is excavated with a first fixing hole, the upper part of the base is excavated with a second fixing hole, the upper end of the spring is clamped into the first fixing hole, and the lower end of the spring is clamped into the second fixing hole.

[0012] The clamping type fixing mode can facilitate the installation of the spring in place during the installation of the equipment without the need for complex tools and operation steps. In the later maintenance stage of the equipment, if the spring needs to be replaced, it can also be easily taken out from the fixing hole and replaced, thereby reducing the maintenance cost and difficulty and improving the maintainability of the equipment.

[0013] Preferably, the bottom of the lifting platform is provided with a buffer pad, and the buffer pad is located on the stroke of the output end of the lifting power unit.

[0014] When the output end of the lifting power unit is pushed out, it first contacts the buffer pad to slow down the impact force between them, thereby avoiding damage to the output end of the lifting power unit and the bottom of the lifting platform caused by hard collision, and prolonging the service life of the key components of the equipment.

[0015] Preferably, the bottom of the lifting platform is excavated with a groove, and the buffer pad is arranged in the groove.

[0016] The buffer pad is placed in the groove to provide accurate positioning for the buffer pad, so that it always remains in the correct position during the operation of the equipment. The shape and size of the groove match those of the buffer pad, which can effectively limit the movement range of the buffer pad and ensure that it does not deviate or shake when bearing the impact force. This is crucial to ensure that the buffer pad can play the best buffering effect, and the buffer pad can accurately play a role on the stroke of the output end of the lifting power unit, providing reliable protection for the equipment for a long time.

[0017] Preferably, the lower surface of the buffer pad is flush with the lower surface of the lifting platform.

[0018] This design ensures the overall flatness of the bottom of the lifting platform, avoiding the problem of space interference that may occur during the operation of the equipment.

[0019] Preferably, the spring has two, and the two springs are symmetrically distributed on both sides of the center line of the lifting platform.

[0020] The symmetrical design provides the lifting platform with balanced load-bearing capacity and stable support effect. When bottles are placed on the lifting platform for filling operation, the two symmetrical springs can evenly share the weight of the bottles and the lifting platform itself, avoiding tilting or shaking of the lifting platform due to uneven force.

[0021] Preferably, the lifting power unit is arranged on the center line of the base.

[0022] The lifting power unit is placed on the center line of the base, which can ensure that the driving force is transmitted along the central axis of the lifting platform. This means that when the lifting platform is lifted, the power transmission is more direct and accurate, avoiding unnecessary twisting or deviation of the lifting platform during movement due to eccentric driving force. Precise driving force transmission enables the lifting platform to move strictly in the predetermined vertical direction, ensuring the accuracy of the bottle position during lifting, thereby providing a strong guarantee for accurate filling operation. The descent of the lifting platform is mainly due to the increased weight of the full bottle overcoming the spring force, thereby causing the lifting platform to descend.

[0023] A filling machine comprising the lifting sterile filling module as described above.

[0024] The utility model discloses the beneficial effect compared with prior art is:

[0025] The lifting sterile filling module of the utility model, when the bottle is in the empty state and the lifting power unit does not contact the lifting platform, the liquid filling pipeline locally extends into the bottle. This design can accurately position the liquid filling pipeline in the appropriate position inside the bottle before filling starts, ensuring that the liquid can be directly injected into the bottom of the bottle, avoiding liquid splashing or remaining near the bottle mouth, effectively improving the accuracy and hygiene of filling. At the same time, when the bottle is in or close to the full state and the lifting power unit does not contact the lifting platform, the gravity acting on the lifting platform increases, and the greater gravity forces the lifting platform to descend, and the liquid filling pipeline is fully extended outside the bottle, avoiding contact between the outer surface of the liquid filling pipeline and the liquid, ensuring the purity of the filled liquid.

[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0034] The technical solutions in the present application will be described below in combination with the accompanying drawings.

[0035] The present embodiment provides a lifting type sterile filling module arranged between a front conveying belt and a rear conveying belt, comprising a base 100, a lifting platform 300 movably connected to the base 100 by a spring 200 and used for carrying a bottle 001, a lifting power unit 400 used for lifting the lifting platform 300, a liquid filling pipeline 500 used for filling liquid into the bottle, and a liquid filler 600 in communication with the liquid filling pipeline 500. The lifting power unit 400 is arranged below the lifting platform 300, and the lifting platform 300 can be at the same height as the front conveying belt and the rear conveying belt under the action of the lifting power unit 400. When the bottle is in an empty state and the lifting power unit 400 does not contact the lifting platform 300, the liquid filling pipeline 500 partially extends into the bottle. When the bottle is in or close to the empty state and the lifting power unit 400 does not contact the lifting platform 300, the liquid filling pipeline 500 completely extends out of the bottle.

[0036] When the bottle is empty and the lifting power unit 400 is not in contact with the lifting platform 300, the filling pipe 500 partially extends into the bottle. This design allows the filling pipe 500 to be accurately positioned inside the bottle before filling begins, ensuring that the liquid is injected directly to the bottom of the bottle, preventing splashing or residue near the bottle opening, and effectively improving filling accuracy and hygiene. Simultaneously, when the bottle is at or near full load and the lifting power unit 400 is not in contact with the lifting platform 300, the lifting platform 300 experiences increased gravity. This increased gravity forces the lifting platform 300 to descend, and the filling pipe 500 extends completely outside the bottle, preventing contact between the filling pipe 500's outer surface and the liquid, thus ensuring the purity of the filled liquid.

[0037] In this embodiment, the base 100 is connected to a first guard plate 110 and a second guard plate 120 on both sides, and the first guard plate 110 and the second guard plate 120 extend upward to above the highest point of the travel of the lifting platform 300.

[0038] The safety and protection of the entire lifting aseptic filling module are enhanced. During equipment operation, the first protective plate 110 and the second protective plate 120 prevent foreign objects from accidentally falling into the equipment, avoiding interference with the normal operation of the filling module and preventing mechanical failure or product contamination caused by foreign objects entering. Especially in some complex factory workshops where dust, debris, and other debris may exist, the protective plates effectively resist these potential threats, ensuring that the filling module always operates in a relatively clean and safe environment. For operators, the protective plate extending upwards to the highest point of the lifting platform 300 provides a reliable protective barrier. During the up-and-down movement of the lifting platform 300, it prevents operators from accidentally touching moving parts, avoiding personal injury caused by accidental contact. This not only ensures employee safety but also complies with relevant safety production regulations and requirements, reducing safety risks for the enterprise during the production process. From an overall structural perspective, the installation of the first protective plate 110 and the second protective plate 120 enhances the integrity and stability of the equipment. They are tightly connected to the base 100, acting as part of the frame structure, providing additional support and reinforcement for the entire filling module. During equipment operation, it can better resist vibration and external impact, reduce the impact of equipment shaking on filling accuracy, and help maintain the stability and consistency of filling operations.

[0039] In this embodiment, sliders 310 are provided on both sides of the lifting platform 300, and the first guard plate 110 and the second guard plate 120 are provided with slide rails 130 that are slidably connected to the sliders 310.

[0040] The cooperation between the sliding block 310 and the sliding rail 130 provides precise guidance for the up-and-down movement of the lifting platform 300. When the lifting platform 300 is ascending or descending, the sliding block 310 slides smoothly along the sliding rail 130, ensuring that the lifting platform 300 always moves in the predetermined vertical direction, greatly improving the straightness and stability of the movement of the lifting platform 300.

[0041] In this embodiment, the bottom of the lifting platform 300 is excavated with a first fixing hole 320, the upper part of the base 100 is excavated with a second fixing hole 140, the upper end of the spring 200 is inserted into the first fixing hole 320, and the lower end of the spring 200 is inserted into the second fixing hole 140.

[0042] The fixing method of insertion makes it convenient and fast for the staff to install the spring 200 in place during the installation process of the equipment, without the need for complex tools and operation steps. In the later maintenance stage of the equipment, if the spring 200 needs to be replaced, it can also be easily taken out from the fixing hole and replaced, reducing the maintenance cost and difficulty and improving the maintainability of the equipment.

[0043] In this embodiment, the bottom of the lifting platform 300 is provided with a buffer pad 330, which is located on the stroke of the output end of the lifting power unit 400.

[0044] When the output end of the lifting power unit 400 is pushed out, it first contacts the buffer pad 330, reducing the impact force between them and avoiding damage to the output end of the lifting power unit 400 and the bottom of the lifting platform 300 due to hard collision, prolonging the service life of the key components of the equipment.

[0045] In this embodiment, the bottom of the lifting platform 300 is excavated with a groove 340, and the buffer pad 330 is arranged in the groove 340.

[0046] The buffer pad 330 is placed in the groove 340, which provides precise positioning for the buffer pad 330, so that it always remains in the correct position during the operation of the equipment. The shape and size of the groove 340 match those of the buffer pad 330, effectively limiting the movement range of the buffer pad 330 and ensuring that it does not shift or shake when subjected to impact force. This is crucial for ensuring that the buffer pad 330 functions optimally, regardless of how long the equipment has been running, and consistently provides reliable protection for the equipment.

[0047] In this embodiment, the lower surface of the buffer pad 330 is flush with the lower surface of the lifting platform 300.

[0048] This design ensures the overall flatness of the bottom of the lifting platform 300, avoiding potential spatial interference problems during the operation of the equipment.

[0049] In the embodiment, the two springs 200 are symmetrically distributed on both sides of the center line of the lifting platform 300.

[0050] The symmetric distribution design provides the lifting platform 300 with balanced bearing capacity and stable support effect.

[0051] In the embodiment, the lifting power unit 400 is arranged on the center line of the base 100.

[0052] Arranging the lifting power unit 400 on the center line of the base 100 can ensure that the driving force is transmitted along the central axis of the lifting platform 300. This means that when the lifting platform 300 is lifted, the power transmission is more direct and accurate, avoiding unnecessary twisting or deviation of the lifting platform 300 during movement due to eccentric driving force. Precise driving force transmission enables the lifting platform 300 to move strictly in the predetermined vertical direction, ensuring the positional accuracy of the bottles during lifting, thereby providing a strong guarantee for accurate filling operation. The descent of the lifting platform 300 is mainly due to the increased weight of the bottles after being filled, which overcomes the elastic force of the springs 200, thereby causing the lifting platform 300 to descend.

[0053] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
