Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to a linear flow meter type quantitative filling machine. Background Technology

[0002] As an important branch of packaging machinery, filling machines are widely used, especially in the daily chemical and oil industries, for liquid filling. These machines are responsible for accurately filling product solutions into containers such as glass bottles and plastic bottles to meet market sales demands.

[0003] However, traditional filling machines often face leakage problems due to residual solution inside the filling head after shutdown. This not only increases the complexity of subsequent cleaning but also, because the controller operates multiple filling pumps simultaneously, a failure in one pump can reduce its pumping efficiency, making it impossible to accurately fill individual containers and thus affecting overall product quality. Therefore, improving the accuracy and cleaning efficiency of filling machines has become an urgent problem to be solved in the industry. Utility Model Content

[0009] Optionally, it also includes a telescopic rod, a lifting plate, a sliding rod, a fixed plate, a limiting plate, and an electric push rod b.

It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] Example: Linear flow meter type quantitative filling machine, such as Figures 1-4As shown, the device includes a base 1, with a cabinet 2 bolted to the top of the base 1. The cabinet 2 is a shell with openings on the front and bottom. A transparent cabinet door 21 is symmetrically and rotatably connected to the front of the cabinet 2. A partition 22 is bolted to the middle of the inner wall of the cabinet 2. A conveyor belt 23 is fixedly connected to the front top of the base 1. The left and right ends of the conveyor belt 23 pass through the left and right panels of the cabinet 2, respectively. Symmetrical baffles 24 are arranged on the top of the conveyor belt 23. Slide rails a25 are symmetrically bolted to the front of the conveyor belt 23. Each slide rail a25 has a sliding mounting bracket. The cabinet 2 includes a mounting bracket a26, with an electronic eye 27 on each of the two mounting brackets a26, and an electric push rod a28 on each of the two slide rails a25. A controller 29 is installed on the top right side of the cabinet 2. The cabinet also includes a filling assembly, a pumping assembly, and a back suction assembly. A filling assembly for injecting product solution into the container to be filled is installed on the partition 22. A pumping assembly for pumping product solution into the filling assembly is installed on the top of the base 1. A back suction assembly is installed on the filling assembly to remove the product solution remaining in the filling assembly.

[0020] like Figure 2 and Figure 3 As shown, the injection assembly includes a slide rail b31, a lifting frame 32, a cylinder 321, a mounting plate 33, and an injection head 34. The slide rail b31 is symmetrically fixed to the front side wall of the partition 22 by bolts. The lifting frame 32 is slidably connected between the two slide rails b31. The cylinder 321 is installed on the front side wall of the partition 22 by bolts. The piston rod end of the cylinder 321 is fixedly connected to the lifting frame 32. Multiple mounting plates 33 are arranged at intervals on the front side of the lifting frame 32. An injection head 34 is welded and fixed on each mounting plate 33.

[0021] like Figure 2 and Figure 3 As shown, the pump assembly includes a supply pump 41, a circular pipe 42, a filling pump 43, a linear flow meter 44, a solenoid valve 45, a check valve 46, and a filling pipe 47. The supply pump 41 is bolted to the rear top of the base 1. The supply pump 41 is connected to an external product storage device. The circular pipe 42 is fixedly connected to the top of the supply pump 41. The supply pump 41 is used to pump the external product solution into the circular pipe 42. Multiple filling pumps 43, which are matched with the filling head 34, are connected at intervals to the top of the circular pipe 42. Each filling pump 43 has a top opening... A linear flow meter 44 is connected via a flange. Each linear flow meter 44 is connected to a solenoid valve 45 via a flange at its top. The solenoid valve 45 is used to prevent the product solution in the circular pipe 42 from flowing into the injection pipe 47. Each solenoid valve 45 is connected to a check valve 46 via a flange at its top. The check valve 46 is used to prevent the product solution in the injection pipe 47 from flowing back downwards. Each check valve 46 is connected to the injection pipe 47 at its top. The upper part of the partition 22 has three openings at intervals. The injection pipe 47 passes through the partition 22 from the openings and is connected to the injection head 34.

[0022] like Figure 2 and Figure 3 As shown, the back suction assembly includes a back suction pump 51, a back suction pipe 52, a guide pipe 53, a collection cylinder 54, a connecting pipe 55, and a balance pipe 56. Each injection head 34 has a back suction pump 51 at its top, and a back suction pipe 52 is connected to the rear of each back suction pump 51. The back suction pipe 52 passes through the partition 22 through an opening in the partition 22, and the end of the back suction pipe 52 furthest from the back suction pump 51 is connected to the guide pipe 53. The guide pipe 53 penetrates the right panel of the cabinet 2, and a collection cylinder is fixedly connected to the right side of the cabinet 2. The right end of the guide pipe 53 is connected to the collection cylinder 54 by a connecting pipe 55. The top rear side of the collection cylinder 54 is connected to a balance pipe 56. The balance pipe 56 is used to discharge the gas in the collection cylinder 54 when liquid is injected into the collection cylinder 54 by the connecting pipe 55, thereby maintaining the gas pressure balance in the collection cylinder 54. The controller is electrically connected to the conveyor belt 23, the electronic eye 27, the electric push rod a28, the cylinder 321, the liquid supply pump 41, the filling pump, the linear flow meter, the solenoid valve, and the back suction pump.

[0023] When using this filling machine, the operator first connects the left side of the conveyor belt 23 to the external feeding device. The external feeding device is responsible for transporting the containers to be filled onto the conveyor belt 23 in an orderly manner. Then, the operator starts the controller 29, which activates the conveyor belt 23 to begin operation. The conveyor belt 23 transports the containers to be filled one by one to the right until the container on the far right is blocked by the telescopic rod extending from the right-side electric push rod a28. At this point, the electronic eye 27 on the right side will also detect this state and send a signal. The signal is sent to controller 29. Upon receiving the signal, controller 29 immediately activates the left-side electric push rod a28, extending its telescopic rod to block the containers to be filled on the left, ensuring all containers are in a stable state. Subsequently, controller 29 activates cylinder 321, whose piston rod retracts, causing the lifting frame 32 to move smoothly downwards along slide rail b31. The movement of the lifting frame 32 then causes the filling head 34 to gradually approach the adjacent container to be filled. Once the filling head 34 is in position, controller 29 activates the liquid supply pump 41 to supply liquid. Pump 41 starts working, gradually filling the circular tube 42 with product solution. Then, controller 29 starts filling pump 43. Filling pump 43 pumps the product solution from the circular tube 42 through linear flow meter 44, solenoid valve 45, and check valve 46 into filling pipe 47. The product solution flows from filling pipe 47 into filling head 34 and is finally injected into the container to be filled. As the product solution passes through linear flow meter 44, linear flow meter 44 records and transmits data to controller 29 in real time. Based on this data, controller 29 adjusts the flow rate of each filling pump 43. Precise control ensures that each filling pump 43 injects a fixed amount and the same volume of product solution into the container to be filled, thereby improving product quality and consistency. During the shutdown phase, the operator can start the back suction pump 51 through the controller 29. The back suction pump 51 starts working, extracts the residual product solution in the filling head 34, and injects it into the collection cylinder 54 through the back suction pipe 52, the guide pipe 53 and the connecting pipe 55. This step effectively prevents the product solution from dripping from the filling head 34 onto the conveyor belt 23, reducing the trouble of subsequent cleaning.

[0024] like Figure 4 As shown, it also includes a telescopic rod 61, a lifting plate 62, a sliding rod 63, a fixing plate 64, a limiting plate 65, and an electric push rod b651. Two telescopic rods 61 are fixedly bolted to the front top of the base 1. The lifting plate 62 is fixedly connected between the tops of the two telescopic rods 61. Sliding rods 63 are slidably connected to both sides of the lifting plate 62. The fixing plate 64 is welded and fixed between the rear ends of the two sliding rods 63. Multiple limiting plates 65 matching the injection head 34 are spaced apart on the fixing plate 64. An electric push rod b651 is bolted to the middle of the top of the lifting plate 62. The end of the telescopic rod 61 of the electric push rod b651 is fixedly connected to the fixing plate 64. The electric push rod b651 is electrically connected to the controller 29.

[0025] When the container to be filled is blocked by the electric push rod on the right side of the conveyor belt 23, the controller 29 will control the electric push rod b651 to start. The telescopic rod of the electric push rod b651 extends and pushes the fixed plate 64 to move smoothly backward under the guidance of the slide rod 63. This allows the V-shaped groove on the rear side of the limiting plate 65 to fit tightly against the neck of the container to be filled, effectively avoiding leakage caused by the container shaking during the filling process.

[0026] like Figure 4 As shown, it also includes a mounting frame b66, a U-shaped sliding plate a67, a U-shaped sliding plate b68 and a support plate 69. The mounting frame b66 is welded and fixed to the rear side of the conveyor belt 23. The U-shaped sliding plate a67 is slidably connected to the upper part of the mounting frame b66. The U-shaped sliding plate b68 is slidably connected to the upper part of the U-shaped sliding plate a67. The support plate 69 is welded and fixed to the front side of the U-shaped sliding plate.

[0027] To meet the filling needs of containers of different sizes, the position of the U-shaped sliding plate a67 and the U-shaped sliding plate b68 can be adjusted. By adjusting the position of these two sliding plates, it can be ensured that the front side of the support plate 69 can fit tightly against the rear side of the neck of the container to be filled. When the limiting plate 65 limits the container to be filled, the limiting plate 65 will push the container to fit tightly against the support plate 69. The presence of the support plate 69 provides stable support for the container and avoids the problem of deformation in the middle of the container when filling plastic containers.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
