DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figures 1 to 11 As shown, the utility model provides:

[0030] A quantitative filling machine for liquid electronic chemicals comprises a conveying frame 1 and an output frame 12, wherein a frame 3 is arranged between the conveying frame 1 and the output frame 12, arc-shaped baffles 5 are arranged on both side outer walls of the conveying frame 1 and the output frame 12, a support plate 4 is arranged inside the frame 3, a second motor 13 is arranged on the top of the support plate 4, a placement plate 6 is arranged on the output shaft of the second motor 13, a plurality of notches for placing quantitative bottles 2 are opened on the top of the placement plate 6, a support rod 7 is arranged on the top of the placement plate 6, a disc 26 is arranged on the top of the support rod 7, a liquid storage barrel 11 and a plurality of first motors 10 are arranged on the top of the disc 26, the output shaft of the first motor 10 passes through the disc 26 and is connected to a turntable 14, and a capping assembly and a filling assembly are arranged on the bottom of the turntable 14.

[0031] The conveying frame 1 and the output frame 12 can be used to realize automatic filling and capping of the quantitative bottles 2.

[0032] Figure 5As shown, the sealing assembly includes a second plug cylinder 17 and a hydraulic rod 16, the telescopic end of the hydraulic rod 16 is provided with a connecting block 18, the interior of the connecting block 18 is provided with a through hole adapted to the second plug cylinder 17, the bottom of the connecting block 18 is provided with an electric clamp 19, and the clamping end of the electric clamp 19 is provided with an arc-shaped clamping block 25.

[0033] The hydraulic rod 16 drives the connecting block 18, the electric clamp 19 and the plug 24 to move downward. Since a through hole compatible with the second plug cylinder 17 is provided inside the connecting block 18, the second plug cylinder 17 will not move. During the downward movement of the plug 24, the bottle mouth of the quantitative bottle 2 will be sealed, avoiding human sealing.

[0034] like Figure 4 and Figure 5 As shown, the filling assembly includes an electric push rod 15, a connecting plate 20 is provided at the telescopic end of the electric push rod 15, a solenoid valve 22 is provided at the bottom of the connecting plate 20, a sensor 21 is provided at the top of the solenoid valve 22, and a discharge pipe 23 is connected to the bottom of the solenoid valve 22.

[0035] The sensor 21 senses and controls the electric push rod 15 to move downward, driving the discharge pipe 23 to be located just above the mouth of the quantitative bottle 2, and then the electromagnetic valve 22 is used to quantitatively fill the quantitative bottle 2.

[0036] like Figure 5 As shown, the interior of the liquid storage barrel 11 is connected to a material delivery pipe 8 , and the other end of the material delivery pipe 8 is connected to a solenoid valve 22 .

[0037] The liquid in the liquid storage barrel 11 can be transported to the inside of the discharge pipe 23 by means of the conveying pipe 8 .

[0038] like Figure 1 and Figure 2 As shown, a plurality of first plug storage tubes 9 are arranged on the top of the placement plate 6, and plugs 24 are placed inside the first plug storage tubes 9 and the second plug storage tubes 17. The outer wall of the plug 24 is provided with an annular groove adapted to the arc-shaped clamping block 25.

[0039] The second plug storage cylinder 17 and the first plug storage cylinder 9 can store a plurality of plugs 24 to facilitate the capping process of the quantitative bottle 2.

[0040] like Figure 1 and Figure 7 As shown, the interiors of the rotating disk 14 and the circular disk 26 are both provided with through holes adapted to the first plug storage cylinder 9 and the second plug storage cylinder 17.

[0041] A plurality of plugs 24 are stored inside the first plug cylinder 9. When one of the plugs 24 inside the first plug cylinder 9 is used, the plug 24 inside the second plug 24 will naturally fall into the second plug 24 through the internal through holes of the turntable 14 and the disc 26 for replenishment.

[0042] like Figure 6 As shown, an arc-shaped block 28 is symmetrically installed inside the second plug storage tube 17, and a plurality of spacer springs 27 are arranged on the back of the arc-shaped block 28, and one end of the spring 27 is connected to the inner wall of the second plug storage tube 17.

[0043] In order to prevent the plugs 24 inside the second plug cylinder 17 and the first plug cylinder 9 from falling, an arc-shaped block 28 and a spring 27 are provided inside the second plug cylinder 17. When the bottom plug 24 goes down, the second-to-last plug 24 will be clamped between the two arc-shaped blocks 28 to prevent the plug 24 from falling.

[0044] like Figure 7 As shown, conveyor belts are arranged inside the conveying frame 1 and the output frame 12 .

[0045] The conveyor belt is used to facilitate the transportation and output of the quantitative bottle 2.

[0046] Working principle: First, the staff will place the quantitative bottle 2 to be filled inside the conveying frame 1, and it will move to the gap at the top of the placement plate 6 through the conveyor belt inside the conveying frame 1, and then the placement plate 6 will be driven to rotate by the second motor 13, and the arc baffle 5 will be used to prevent the quantitative bottle 2 from falling while rotating. When the quantitative bottle 2 moves to the placement plate 6, it is sensed by the sensor 21 and the electric push rod 15 is controlled to move downward, driving the discharge pipe 23 to be located just above the bottle mouth of the quantitative bottle 2. Then, the electromagnetic valve 22 is used to quantitatively fill the quantitative bottle 2. When the filling is completed, , the telescopic end of the electric push rod 15 moves upward, and when it rises to a certain distance, the first motor 10 drives the turntable 14 to rotate 180 degrees, so that the second plug cylinder 17 is located just above the mouth of the quantitative bottle 2. At this time, the two electric clamps 19 approach each other, driving the arc clamping block 25 to embed into the annular groove on the outer wall of the plug 24. Then the hydraulic rod 16 works to drive the connecting block 18, the electric clamping jaws 19 and the plug 24 to move downward. Since the connecting block 18 is provided with a through hole adapted to the second plug cylinder 17, the second plug cylinder 17 will not move, and the plug 24 During the downward movement, the mouth of the quantitative bottle 2 will be capped to avoid human capping. Then the two electric clamps 19 will move outward at the same time, away from the annular groove on the outer wall of the plug 24. Then the movable end of the hydraulic rod 16 will rise. At this time, the first motor 10 drives the turntable 14 to rotate 180 degrees in the opposite direction, and the filled and capped quantitative bottle 2 will be transferred through the transport frame to facilitate the next step. In order to prevent the plug 24 inside the second plug cylinder 17 and the first plug cylinder 9 from falling, an arc-shaped block 28 and a spring 27 are arranged inside the second plug cylinder 17. When the bottom plug 2 4, the penultimate plug 24 will be stuck between the two arc-shaped blocks 28 to prevent the plug 24 from falling. At the same time, a plurality of plugs 24 are stored in the first plug storage cylinder 9. When one plug 24 in the first plug storage cylinder 9 is used, the plug 24 in the second plug 24 will naturally fall into the second plug 24 through the internal through holes of the turntable 14 and the disc 26 for replenishment. Because the plug 24 at the highest point of the second plug 24 is level with the highest point of the turntable 14, the turntable 14 will block the plug 24 in the first plug storage cylinder 9 when it rotates.

[0047] The above embodiments only express a liquid electronic chemical quantitative filling machine or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
