Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to a filling equipment. Background Art

[0002] Biochemical research, medical diagnostics, clinical testing laboratories, and IVD companies use manual and mechanical filling methods for liquid medicine. Manual filling is inefficient, imprecise, and prone to leaks. Due to the significant cost and efficiency disparity between manual filling and sub-packaging, automated filling machines are currently being used in industries such as food and beverages, daily toiletries and cosmetics, and pharmaceuticals to replace manual filling.

[0003] Filling machines typically consist of five components: an automatic bottle loading system, an automatic liquid adding system, an automatic foil heat-sealing system, a control and operating system, and a main engine turntable drive system. Existing filling equipment uses a heated punch blade for automatic foil heat-sealing. The foil is heat-sealed directly after being punched onto the sealing surface. Because the punch blade is heated, melted foil can stick to it during return. This results in frequent blade cleaning, impacting equipment operation and reducing production efficiency. Summary of the Invention

[0011] A blanking assembly, which is arranged downstream of the heat-sealing assembly and is used to transfer the bottles heat-sealed on the transfer assembly to a blanking chute;

[0012] Among them, a trial cutting mold is placed on the transfer component, and a limiting groove matching the punch is set on the trial cutting mold, which is used to limit the aluminum foil on the bottle before heat sealing; and a spring column is set in the punch to allow the aluminum foil to separate from the punch after punching.

[0013] Furthermore, a limiting block is provided below the limiting groove so that there is a spacing distance between the sealing end surface of the bottle in the trial cutting mold and the bottom surface of the limiting groove, so that the edge of the sealing end surface of the bottle can be deformed downward when heated.

[0014] Furthermore, the heat sealing assembly includes a heating knife, a fixed seat, and a lifting cylinder. The heating knife is installed on the fixed seat, and the fixed seat is connected to the lifting cylinder through a connecting block. A floating shaft is provided between the fixed seat and the connecting block, and a spring is provided around the floating shaft.

[0015] Furthermore, the punching assembly also includes a clamping block for clamping the punching knife, the clamping block is slidably mounted on the fixed plate, and the clamping block is connected to a driving cylinder via a torque rod.

[0016] Furthermore, the loading assembly includes a loading base, a first loading cylinder, a second loading cylinder, a vacuum suction rod and a suction cup arranged at one end of the vacuum suction rod. A material guide trough is provided on the loading base, the first loading cylinder is connected to the second loading cylinder, and the vacuum suction rod is connected to the second loading cylinder; when loading, the first loading cylinder drives the vacuum suction rod to move horizontally, the second loading cylinder drives the vacuum suction rod to move up and down, and the suction cup adsorbs the bottle and transfers the bottle from the material guide trough to the transfer assembly.

[0017] Furthermore, a material dividing assembly is provided at one end of the loading base, and the material dividing assembly is used to separate the bottles in the material guide trough; the material dividing assembly includes a dividing plate and a bottle dividing cylinder, and the dividing plate extends into the material guide trough through the opening on the material guide trough, and the dividing plate and the inner wall of the material guide trough form a separation space, and the bottles in the separation space are separated from other bottles in the material guide trough.

[0018] Furthermore, the limiting groove has a water drop-shaped structure.

[0019] Furthermore, the spacing distance is greater than 0.25 mm.

[0020] Furthermore, three spring columns are provided, and the spring columns are distributed in a triangular shape.

[0021] Furthermore, the transfer assembly includes a turntable, and the loading assembly, liquid adding assembly, punching assembly, heat sealing assembly and unloading assembly are arranged at intervals around the turntable.

[0022] The filling equipment in the above embodiment is arranged on one side of the transfer component by dividing the punching component and the heat sealing component into two workstations. Since the punching knife does not need to be heated when punching the aluminum foil, the aluminum foil is "cold" punched, and the aluminum foil after punching will not stick to the punching knife. In this way, there is no need to stop the filling equipment to clean the punching knife during operation, which greatly improves production efficiency and avoids safety hazards in the process of cleaning the punching knife. A spring column is arranged in the punching knife. After the punching is completed, the spring column pops out to make the aluminum foil separate from the punching knife, so that the aluminum foil falls into the limit groove. The design is ingenious and reduces the unqualified rate in production. At the same time, the limit groove can prevent the aluminum foil from deviating during operation, resulting in the inability to heat seal. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Currently, industries such as food and beverages, daily toiletries and cosmetics, and pharmaceuticals are using automated filling machines to replace manual filling. However, in existing filling equipment, the punching and heat sealing of aluminum foil bags are integrated into a single structure. That is, the punching blade is heated, and after the punching is completed, the heat seal is directly performed. Although the structure is simple, when the punching blade is in a high temperature state, the punching blade will stick to the molten aluminum foil. This requires regular shutdowns during the production process to clean the punching blade, affecting production efficiency and shortening the service life of the punching blade. The present application provides a filling device that separates the punching and heat sealing of aluminum foil, performs cold punching on the aluminum foil, avoids the problem of the punching blade sticking to the aluminum foil, and greatly improves production efficiency.

[0038] like Figure 1 As shown, the present application provides a filling device, including a transfer component 10, a loading component 20, a liquid adding component 30, a punching component 40, a heat sealing component 50 and a discharge component 60; wherein the transfer component

[0039] Component 10 is used to place bottles

[0040] And the bottle is transferred from one station to the next station, the loading component

[0041] 20 is arranged on one side of the transfer component 10, the loading component 20 is used to place the bottle on the transfer component 10, the liquid adding component 30 is arranged downstream of the loading component 20, the liquid adding component 30 is used to add liquid to the bottle on the transfer component 10, the punching component 40 is arranged downstream of the liquid adding component 30, the punching component 40 includes a punching knife 43, the punching component 40 is used to punch the aluminum foil on the material rack 70 to the sealing end surface of the bottle on the transfer component 10, the heat sealing component 50 is arranged downstream of the punching component 40, the heat sealing component 50 is used to heat seal the aluminum foil on the sealing end surface to the bottle, the unloading component 60 is arranged downstream of the heat sealing component 50, the unloading component 60 is used to transfer the heat-sealed bottle on the transfer component 10 to the unloading trough 311.

[0042] The filling equipment in the above embodiment is arranged on one side of the transfer component by dividing the punching component and the heat sealing component into two workstations. Since the punching knife does not need to be heated when punching the aluminum foil, the aluminum foil is punched "cold". The aluminum foil after punching will not stick to the punching knife. In this way, there is no need to stop the filling equipment to clean the punching knife during operation, which greatly improves production efficiency and avoids safety hazards in the process of cleaning the punching knife.

[0043] In this embodiment, a trial cutting mold 11 is provided on the transfer assembly, and a limiting groove 111 matching the punching knife 43 is provided on the trial cutting mold 11, which is used to limit the aluminum foil on the bottle before heat sealing; and a spring column 431 is provided in the punching knife 43 to allow the aluminum foil to separate from the punching knife after punching. Preferably, the limiting groove 111 is in a water drop shape, and the limiting groove 111 with a water drop shape matches the punching knife. The aluminum foil after punching by the punching knife is also in a water drop shape, so that there is some excess aluminum foil after sealing the bottle mouth, which is convenient for the user to tear the aluminum foil from the bottle mouth. Figure 2 and Figure 3 shown.

[0044] Furthermore, there are three spring columns 431, and the spring columns are distributed in a triangular shape. The triangular distribution of the spring columns is similar to the shape of the aluminum foil, which can make the aluminum foil after punching fall smoothly into the limiting groove and correspond to the bottle mouth, thereby improving the packaging effect and avoiding leakage after heat sealing. Figure 4 shown.

[0045] In a specific application, the bottle is placed in the trial cutting mold 11, and a spring column 431 is set in the punch. After the punching is completed, the spring column 431 pops out to make the aluminum foil separate from the punch, so that the aluminum foil falls into the limiting groove 111. The design is ingenious and reduces the defective rate in production. At the same time, the limiting groove can prevent the aluminum foil from deviating during operation, resulting in the failure of heat sealing.

[0046] In some embodiments, a limiting block 12 is provided below the limiting groove 111, so that a distance exists between the sealing end surface of the bottle in the trial cutting mold 11 and the bottom surface of the limiting groove 111, so that the edge of the sealing end surface of the bottle can be deformed downward when heated; Figure 2 shown.

[0047] Furthermore, the spacing distance is greater than 0.25 mm, preferably 0.3 mm.

[0048] In a specific application, when the bottle is heat-sealed, since the sealing end face of the bottle is higher than the bottom surface of the limiting groove 111, the sealing end face of the bottle is suspended in the air. When the heating knife 55 of the heat-sealing assembly 50 contacts the sealing end face of the bottle, the edge of the sealing end face is softened by the heat and deforms downward. At this time, the edge of the sealing end face is no longer in contact with the aluminum foil, so the edge of the sealing end face will not be sealed and a gap will be left. The part of the sealing end face close to the bottle body will not be deformed downward due to the support of the bottle body, so the heating knife 55 can heat-seal the aluminum foil at this part. In this way, when the aluminum foil sealing film of the bottle is torn off, since there is a gap between the aluminum foil sealing film and the bottle mouth, tearing off is convenient, labor-saving, and easy to use.

[0049] In some embodiments, the heat sealing assembly includes a heating knife 55, a fixing seat 54, and a lifting cylinder 52. The heating knife 55 is installed on the fixing seat 54, and the fixing seat 54 is connected to the lifting cylinder 52 through a connecting block 53. A floating shaft 56 is provided between the fixing seat 54 and the connecting block 53, and a spring 57 is provided around the floating shaft 56. Specifically, the heating knife 55 is installed in the fixing seat 54, and the fixing seat is connected to the connecting block installed on the lifting cylinder through a floating shaft, and four springs are provided between the fixing seat and the connecting block. During heat sealing, the lifting cylinder 52 is working, and when the heating knife 55 contacts the aluminum foil on the bottle, since the heating knife 55 is floating, when the sealing end face of the bottle is uneven, the heating knife can adjust itself under the action of the spring and the floating shaft to evenly seal the sealing end face of the bottle, thereby avoiding the occurrence of liquid leakage due to uneven heat sealing. Figure 5 shown.

[0050] In some embodiments, the punching assembly 40 further includes a clamping block 42 for clamping a punching knife 43, the clamping block 42 is slidably mounted on a fixed plate 41, and the clamping block 42 is connected to a driving cylinder 44 via a torque rod 45; specifically, the punching knife is mounted in the clamping block, which is mounted on a slide rail of the fixed plate, and the driving cylinder drives the clamping block equipped with the punching knife to slide on the fixed plate via the torque rod to achieve punching of the aluminum foil, and the force of the driving cylinder is amplified by the torque rod, which facilitates the selection of the driving cylinder and makes the equipment structure more compact. Figure 2Correspondingly, a concave film 46 matching the punching knife is provided below the punching knife 43 , and the aluminum foil on the material rack 70 passes through the concave film 46 . When punching, the punching knife 43 directly punches the aluminum foil from the concave film 46 .

[0051] In some embodiments, the loading assembly includes a loading base 21, a first loading cylinder 22, a second loading cylinder 23, a vacuum suction rod 24 and a suction cup 25 arranged at one end of the vacuum suction rod. A material guide groove 211 is provided on the loading base 21, the first loading cylinder 22 is connected to the second loading cylinder 23, and the vacuum suction rod 24 is connected to the second loading cylinder 23; during loading, the first loading cylinder 22 drives the vacuum suction rod 24 to move horizontally, and the second loading cylinder 23 drives the vacuum suction rod 24 to move up and down, and the suction cup 25 adsorbs the bottle and transfers the bottle from the material guide groove 211 to the transfer assembly 10.

[0052] Furthermore, a material separation component is provided at one end of the loading base 21, and the material separation component is used to separate the bottles in the material guide trough; the material separation component includes a partition plate 26 and a bottle separation cylinder 27, and the partition plate 26 extends into the material guide trough through the opening on the material guide trough 211, and the partition plate 26 and the inner wall of the material guide trough 211 form a separation space, and the bottles in the separation space are separated from other bottles in the material guide trough 211. Specifically, the bottle separation cylinder 27 drives the partition plate 26 to move, and when the vacuum suction rod 24 grabs the bottle, since the partition plate 26 separates the bottle at the end of the material guide trough 211 from other bottles, the vacuum suction rod will not interfere with each other or bring out other bottles in the material guide trough during the process of grabbing the bottle. Figure 6 shown.

[0053] In a specific application, when loading, the material guide chute 211 is connected to the loading vibration plate, and the empty bottles enter the material guide chute through the loading vibration plate.

Figure 8 shown.

[0055] In addition, in this application, the liquid adding component includes a liquid adding needle 31, which is installed on the support rod 33 on one side of the transfer component through an adjusting rod 32. The bottom of the support rod 33 is connected to the liquid adding cylinder 34, and the top of the liquid adding needle 31 is connected to the liquid adding pump through a conduit. In specific applications, the position of the liquid adding needle is adjusted by loosening the fastening screws on the adjusting rod 32 and the support rod 33. The liquid adding cylinder 34 drives the liquid adding needle 31 into the bottle through the support rod 33. When the liquid adding pump is working, liquid can be added to the bottle on the transfer component. Figure 7 shown.

[0056] In this embodiment, the transfer assembly 10 includes a turntable driven by a motor, and the loading assembly, liquid adding assembly, punching assembly, heat sealing assembly, and unloading assembly are spaced apart around the turntable. In specific applications, the turntable is used to transfer bottles between various workstations, improving the compactness of the equipment, reducing the equipment's footprint, and facilitating its transportation and placement.
