Description

Technical Field

[0001] The utility model relates to the technical field of liquid filling, in particular to an upper weighing and pressurizing filling machine. Background Art

[0002] At present, when filling bottled liquids, a filling machine is often used to replace manual filling. During the filling process, the filling machine usually transfers the liquid to be filled from a larger intermediate liquid tank to a weighing tank by its own gravity, weighs the liquid weight in the weighing tank through a weighing component, and then flows the liquid in the weighing tank to a filling head by its own gravity through a corresponding pipeline, and finally fills it into a bottled container.

[0003] However, the filling speed of this filling scheme is limited by the height difference between the weighing tank and the filling head. The larger the height difference, the faster the filling speed. However, due to the limited space of some customers' sites, the height of the filling machine cannot be made too high, and the filling speed is slow or even filling cannot be successfully carried out by its own gravity. Secondly, for liquids with higher viscosity, the filling speed is slow or even filling cannot be successfully carried out by its own gravity.

[0004] Therefore, an upper weighing and pressurizing filling machine is provided to facilitate the rapid filling of the liquid in the weighing tank and to adjust the filling speed. Summary of the Utility Model

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0022] Refer to Figures 1-3 , a top weighing and pressurizing filling machine provided by the present utility model. This top weighing and pressurizing filling machine includes a frame 1. An intermediate liquid tank 11 is provided on the upper side of the frame 1. A weighing tank 2 is provided on the lower side of the intermediate liquid tank 11. A pressurizing port 92 is provided on the upper side of the weighing tank 2. A weighing assembly 3 is provided on the lower side of the weighing tank 2. The frame 1 is provided with a filling pipe 8 for filling. A conveying assembly 7 is provided below the filling pipe 8; A connecting pipeline 5 is provided below the intermediate liquid tank 11. An automatic valve 51 is provided at the top of the connecting pipeline 5. A buffer hose 52 is provided below the automatic valve 51. The other end of the buffer hose 52 is connected to the bottom of one end of the weighing tank 2. A manual valve 6 is provided at the connection of one end of the connecting pipeline 5 and the intermediate liquid tank 11.

[0023] Specifically, for the frame 1, an intermediate liquid tank 11 is provided on the upper side of the frame 1, and a weighing tank 2 is provided on the lower side of the intermediate liquid tank 11. Rapid filling is achieved by increasing the air pressure in the weighing tank 2, and the air pressure in the weighing tank 2 can be set manually, so as to achieve adjustable filling speed; A pressurizing port 92 is provided on the upper side of the weighing tank 2. A connecting pipeline 5 is provided below the intermediate liquid tank 11. An automatic valve 51 is provided at the top of the connecting pipeline 5. A buffer hose 52 is provided below the automatic valve 51. The other end of the buffer hose 52 is connected to the bottom of one end of the weighing tank 2. The weighing tank 2 pressurizes the connecting pipeline 5 through the exhaust valve 9; A weighing assembly 3 is provided on the lower side of the weighing tank 2. A manual valve 6 is provided at the connection of one end of the connecting pipeline 5 and the intermediate liquid tank 11. The weighing tank 2 is weighed by the weighing assembly 3, and the opening and closing of the filling pipe 8 are controlled according to the weight change of the weighing tank 2. When the weight change of the weighing tank 2 is large, the manual valve 6 is controlled to perform operations such as liquid replenishment on the weighing tank 2; The frame 1 is provided with a filling pipe 8 for filling. A conveying assembly 7 is provided below the filling pipe 8. The container is conveyed to the lower part of the filling pipe 8 through the conveying assembly 7.

[0024] The transfer liquid tank 11 is located at the top center of the frame 1. One end of the connecting pipeline 5 is located at the center of the bottom surface of the transfer liquid tank 11. A three-way joint 4 is provided on the connecting pipeline 5, and the other end of the buffer hose 52 is connected to the three-way joint 4.

[0025] Specifically, by installing the three-way joint 4 on the connecting pipeline 5, when the transfer liquid tank 11 replenishes the weighing tank 2 with liquid, due to the principle of communicating vessels, the liquid in the transfer liquid tank 11 can flow into the weighing tank 2 as much as possible. And the process of the liquid entering the weighing tank 2 from the bottom of the weighing tank 2 is relatively slow, effectively slowing down the speed when entering the weighing tank 2, reducing the excessive mixing of the liquid and air during the process of the liquid flowing down from a high place, which affects the liquid quality, and also effectively realizes the connection between the transfer liquid tank 11, the weighing tank 2 and the filling pipe 8.

[0026] One side of the connecting pipeline 5 is parallel to the horizontal plane. A liquid replenishing pipe 81 is provided at the horizontal end of the connecting pipeline 5. A filling nozzle 82 is provided at the bottom of the filling pipe 8. The other end of the liquid replenishing pipe 81 is connected to the filling nozzle 82.

[0027] Specifically, the connecting pipeline 5 connects the filling nozzle 82 with the transfer liquid tank 11 through the liquid replenishing pipe 81 to feed the filling pipe 8.

[0028] An exhaust valve 9 is provided at the top of the weighing tank 2. The axis of the pressurizing port 92 is parallel to the axis of the exhaust valve 9; A exhaust pipe 91 is provided on one side of the exhaust valve 9. The other end of the pressurizing port 92 is provided with a pressurizing pipe 93.

[0029] Specifically, the weighing tank 2 pressurizes the connecting pipeline 5 through the pressurizing port 92 and the pressurizing pipe 93, and discharges the excess gas through the exhaust pipe 91 and the exhaust valve 9.

[0030] A connecting plate 94 is provided on the side of the automatic valve 51 opposite to the weighing tank 2. The connecting plate 94 is connected to the automatic valve 51; The other ends of the exhaust pipe 91 and the pressurizing pipe 93 are connected to the connecting plate 94.

[0031] Specifically, the exhaust pipe 91 and the pressurizing pipe 93 are connected to the connecting pipeline 5 through the connecting plate 94, thereby forming a pressurizing loop.

[0032] The inner wall of the weighing tank 2 is provided with an anti-sticking coating.

[0033] Specifically, by setting an anti-sticking coating inside the weighing tank, it is difficult for the liquid with a relatively high viscosity to remain in the weighing tank 2, effectively facilitating the discharge of the liquid in the weighing tank 2.

[0034] During use, clean compressed air is filled into the weighing tank 2 to make the air pressure in the weighing tank 2 reach the set value, increasing the total pressure in the passage between the transfer liquid tank 11 and the connecting pipeline 5, thereby increasing the liquid flow rate from the weighing tank 2 to the filling pipe 8 to achieve rapid filling; in the later stage of filling, the pressure inside the connecting pipeline 5 is reduced through the exhaust valve 9 to achieve slow filling at normal pressure and improve the filling accuracy.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
