DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0026] like Figure 1-2 As shown, the double-head weighing filling machine in this embodiment includes a base 1, a shell 2, a storage tank 3, a linear module 4, a connecting rod 5, a filling head 6, a conveying assembly 7 and a weighing device 8. The shell 2 is arranged on the upper rear side of the base 1, the storage tank 3 is arranged inside the shell 2, the linear module 4 is arranged on the front side of the shell 2 in the longitudinal direction, the connecting rod 5 is connected to the slider of the linear module 4 in the horizontal direction, and a filling head 5 is provided at each end of the connecting rod 5. The two filling heads 6 are connected to the storage tank 3 through a hose 9. The conveying assembly 7 is arranged on the base 1 and is located below the filling head 3. The weighing device 8 is arranged in the base 1 and is located at the bottom of the conveying assembly 7.

[0027] The base 1 and the shell 2 are made of 304 stainless steel as a whole, which has strong corrosion resistance, bright color, durability and meets GMP requirements.

[0028] The linear module 4 can drive the connecting rod 5 and the filling head 6 to move up and down to adapt to tanks of different heights.

[0029] A gear pump 10 is provided within the housing 2. The feed end of the gear pump 10 is connected to the discharge port of the storage tank 3, and the discharge end of the gear pump 10 is connected to the filling head 6 via a hose 9. As a fluid delivery power source, the gear pump 10 has the advantages of simple structure, easy maintenance, corrosion resistance, and high temperature resistance. Furthermore, it is not highly sensitive to the viscosity of the fluid and can accommodate the delivery of fluids with a wide viscosity range.

[0030] The bottom of the base 1 is also provided with a plurality of universal wheels 11 to facilitate the movement of the filling machine.

[0031] like Figure 3 As shown, the top of the filling head 6 is connected to the connecting rod 5 through a connecting plate 12 and an adjusting bolt 13. A rectangular groove 14 is provided on the connecting plate 12, and the adjusting bolt 13 passes through the rectangular groove 14 to be connected to the connecting rod 5; the lateral position of the connecting plate 12 on the connecting rod 5 can be adjusted by adjusting the bolt 13, thereby changing the distance between the two filling heads 6 to adapt to tanks of different widths.

[0032] like Figure 4 As shown, the conveying assembly 7 includes a conveying bracket 71, a driving motor 72 and a plurality of rollers 73. The conveying bracket 71 is arranged on the weighing device 8. The plurality of rollers 73 are arranged on the conveying bracket 71 at intervals along the horizontal direction and are rotatable. A sprocket 74 is provided at the end of each roller 73. Each sprocket 74 is synchronously connected by a chain 75. The driving motor 72 is connected to the chain 75 through the driving sprocket.

[0033] The bottom of the conveying bracket 71 is supported on the frame of the base 1 through a telescopic rod 76 .

[0034] In the default state, the conveying component 7 is normally pressed on the weighing device 8, and the weight of the weighing device 8 is reset to zero; when the tank body is placed on the conveying component 7, the gear pump 10 starts to work, so that the fluid material in the storage tank 3 flows into the tank body through the filling head 6, and the weight of the tank body and the fluid is pressed on the weighing device 8. When the set weight is reached, the gear pump 10 stops working; the utility model can realize the synchronous filling of two tank bodies through two filling heads 6, which is 2 times more efficient than the existing single-head filling machine.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art.
