Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a double-head weighing filling machine. Background Technology

[0002] Filling machines are a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, they are divided into semi-automatic filling machines and fully automatic filling production lines. For convenient transportation and use of hydraulic oil, hydraulic oil is filled into containers. To ensure that the weight of the hydraulic oil containers is consistent, a liquid weighing filling machine is used. The use of a weighing filling machine ensures the accuracy of the hydraulic oil container weight. Controlled by a controller, the weight of the hydraulic oil container is displayed on the controller, and calibration is performed using weighing. The existing technology has the following problems:

[0003] Chinese patent document CN220010156U discloses a weighing and filling machine, including a base, a support on one side of the top of the base, a material bucket on the top of the support, a conveying pipe connected to the lower end of the material bucket, a connecting pipe connected to one end of the conveying pipe, and a filling pipe connected to the bottom end of the connecting pipe. An anti-drip component is installed inside the connecting pipe. By incorporating this anti-drip component, residual liquid remains on the inner wall of the filling pipe after filling. An electric push rod drives a sealing piston head downwards to seal the filling pipe, thereby controlling the flow of liquid on the inner wall and preventing dripping. Simultaneously, a sponge is used to wipe away the residual liquid on the inner wall of the filling pipe, further preventing dripping after production and achieving clean production. This also avoids waste and reduces production costs for the enterprise.

[0004] In the aforementioned literature, since there is only one electronic scale and a corresponding filling tube above it, the container needs to be placed on the electronic scale each time it is filled, and then the container needs to be removed after filling and then a new container needs to be placed. This results in low overall weighing efficiency of the weighing and filling machine. In addition, the height of the electronic scale in the aforementioned literature is adjusted by the cooperation between bolts, nuts and adjustment holes on the support rod. However, each adjustment requires the bolts and nuts to be disassembled and the electronic scale to be moved up and down manually, and then the bolts and nuts to be installed. The adjustment process is relatively laborious and affects the speed of height adjustment. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0023] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a dual-head weighing and filling machine, including an L-shaped base 1. A dual-head weighing mechanism 2 is provided at the top of the horizontal part of the L-shaped base 1. A lifting adjustment mechanism 3 is provided at the top of the vertical part of the L-shaped base 1. A filling mechanism 4 is provided above the lifting adjustment mechanism 3. A control panel 5 is fixedly installed on the right side of the vertical part of the L-shaped base 1. A motor slot 11 is opened at the top of the horizontal part of the L-shaped base 1. A servo motor 12 is fixedly installed in the inner cavity of the motor slot 11. The dual-head weighing mechanism 2 includes a rotating plate 21. The output shaft of the servo motor 12 is fixedly connected to the bottom center of the rotating plate 21. The top front and rear sides of the rotating plate 21 are... Electronic scales 22 are fixedly installed on both sides of the rotating plate 21. Container barrels 23 are set on the top of both electronic scales 22. Infrared transmitters 24 are fixedly installed on the front and rear sides of the rotating plate 21. Infrared receivers 13 are fixedly installed on the front vertical side of the L-shaped base 1. The infrared receivers 13 and infrared transmitters 24 are located on the same horizontal line. Two L-shaped brackets 211 are fixedly installed on the left and right sides of the rotating plate 21. Connecting blocks 212 are fixedly installed on the upper vertical surfaces of the adjacent L-shaped brackets 211. Arc-shaped guard plates 213 are fixedly installed on the opposite surfaces of the two connecting blocks 212. The two arc-shaped guard plates 213 are located on the left and right sides of the container barrel 23.

[0025] The control panel 5 controls the start and stop of the servo motor 12, servo motor 32, and liquid pump 43 of the filling machine. The control panel 5, electronic scale 22, liquid pump 43, infrared transmitter, and infrared receiver are all existing devices or equipment, or devices or equipment that can be implemented using existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art and are common knowledge in the field, therefore they will not be described in detail. During filling and weighing, the container 23 is placed on two electronic scales 22 respectively, and the control panel 5 is used to start the servo motor 12 in the motor slot 11, thereby driving the rotating plate 21 to rotate. When the infrared rays emitted by the infrared transmitter 24 at one end of the rotating plate 21 are received by the infrared receiver 13, the infrared receiver 13 sends an electrical signal to the servo motor 12, causing the servo motor 12 to stop. At this time, its... The container 23 on top of one of the electronic scales 22 can be filled normally, and the electronic scale 22 is used to weigh the container during filling. When one container 23 is filled, the servo motor 12 is started again to drive the rotating plate 21 to rotate, so that the other electronic scale 22 moves to the bottom of the filling nozzle 46. Similarly, it stops by the cooperation of the infrared transmitter 24 and the infrared receiver 13. When one container 23 is being filled, the other container 23 can be removed from the electronic scale 22 and a new container 23 can be placed on the electronic scale 22 for tare. This process is repeated to alternate filling and weighing of the container 23 on the two electronic scales 22. When the container 23 is placed on the electronic scale 22, the arc-shaped guard plate 213 on the opposite side of the vertical part of the L-shaped bracket 211 can protect the container 23 to a certain extent and prevent it from tipping over.

[0026] like Figure 4 As shown, the filling mechanism 4 includes a fixed base plate 41, a liquid storage tank 42 is fixedly installed on the top of the fixed base plate 41, a liquid pump 43 is fixedly installed at the front end of the liquid storage tank 42, a liquid pump 44 is fixedly connected to the input end of the liquid pump 43, the other end of the liquid pump 44 is fixedly connected to the right side of the liquid storage tank 42, a liquid outlet pipe 45 is fixedly installed at the output end of the liquid pump 43, a filling nozzle 46 is fixedly connected to the bottom end of the liquid outlet pipe 45, the filling nozzle 46 is located directly above the container tank 23, a visualization window 47 is opened on the front side of the liquid storage tank 42, a transparent glass is fixedly installed on the inner side of the visualization window 47, and a liquid filling pipe 48 that penetrates its inner cavity is fixedly connected to the top of the liquid storage tank 42.

[0027] When one of the containers 23 stops below the filling nozzle 46, the liquid in the storage tank 42 can be drawn out through the extraction pipe 44 by starting the liquid pump 43, and injected into the inner cavity of the container 23 through the outlet pipe 45 and the filling nozzle 46. At the same time, the liquid capacity in the inner cavity of the fixed base plate 41 can be observed through the visualization window 47, and replenishment can be made at any time through the liquid addition pipe 48.

[0028] like Figure 5 As shown, the lifting adjustment mechanism 3 includes a lifting adjustment box 31. A servo motor 32 is fixedly installed at the center of the bottom of the inner wall of the lifting adjustment box 31. A threaded rod 33 is fixedly installed on the output shaft of the servo motor 32. A lifting plate 34 is threadedly installed on the outer wall of the threaded rod 33. Lifting columns 35 are fixedly installed on the top left and right sides of the lifting plate 34. The top ends of the two lifting columns 35 extend to the top of the lifting adjustment box 31 and are fixedly connected to the bottom of the fixed base plate 41. Two sliding rods 36 are fixedly installed between the upper and lower sides of the inner wall of the lifting adjustment box 31. The lifting plate 34 is slidably connected to the two sliding rods 36.

[0029] When the filling height needs to be adjusted, simply start the servo motor 32 inside the lifting adjustment box 31 to drive the threaded rod 33 to rotate. With the threaded connection between the lifting plate 34 and the threaded rod 33, the two lifting columns 35 can be controlled to lift the fixed base plate 41 at the bottom of the liquid storage tank 42 upward. When the lifting plate 34 moves up and down, the sliding connection with the two slide rods 36 can maintain the stability of the lifting and lowering, which ultimately increases the distance between the filling nozzle 46 and the container 23, making it easier to fill the container 23 higher and to make it easier for the filling nozzle 46 to be aligned with the inlet of the container 23 when the fixed base plate 41 is lowered.

[0030] The working principle of this dual-head weighing and filling machine will be explained in detail below.

[0031] like Figure 1-5As shown, during filling and weighing, the container 23 is placed on two electronic scales 22 respectively, and the servo motor 12 in the motor slot 11 is started using the control panel 5, thereby driving the rotating plate 21 to rotate. When the infrared rays emitted by the infrared emitter 24 at one end of the rotating plate 21 are received by the infrared receiver 13, the infrared receiver 13 sends an electrical signal to the servo motor 12, causing the servo motor 12 to stop. At this time, the container 23 on top of one of the electronic scales 22 can be filled normally, and the electronic scale 22 is used for weighing during filling. After one container 23 is filled, the servo motor 12 is restarted to rotate the rotating plate 21, causing the other electronic scale 22 to move below the filling nozzle 46. Similarly, it stops using the cooperation of the infrared transmitter 24 and the infrared receiver 13. While one container 23 is being filled, the other container 23 can be removed from the electronic scale 22, and a new container 23 can be placed on the electronic scale 22 for tare. This process is repeated, alternating between filling and weighing the containers 23 on the two electronic scales 22. When the container 23 is placed on the electronic scale 22... The arc-shaped guard plate 213 on the opposite vertical side of the L-shaped bracket 211 can provide a certain degree of protection for the container 23, preventing it from tipping over. Whenever one of the container 23 stops below the filling nozzle 46, the liquid can be drawn from the storage tank 42 through the extraction pipe 44 by activating the liquid pump 43, and then injected into the inner cavity of the container 23 through the outlet pipe 45 and the filling nozzle 46. At the same time, the filling liquid capacity inside the fixed base plate 41 can be observed through the visualization window 47, and replenishment can be made at any time through the liquid addition pipe 48. The filling volume can also be adjusted as needed. When adjusting the height, simply start the servo motor 32 inside the lifting adjustment box 31 to drive the threaded rod 33 to rotate. With the threaded connection between the lifting plate 34 and the threaded rod 33, the two lifting columns 35 can be controlled to lift the fixed base plate 41 at the bottom of the liquid storage tank 42 upward. When the lifting plate 34 moves up and down, the sliding connection with the two slide rods 36 can maintain the stability of the lifting. Ultimately, the distance between the filling nozzle 46 and the container 23 is increased, which makes it easier to fill the container 23 higher and makes it easier for the filling nozzle 46 to be aligned with the inlet of the container 23 when the fixed base plate 41 is lowered.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
