Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to a precision quantitative liquid filling machine. Background Technology

[0002] Liquid filling machines precisely dispense large quantities of bulk liquid materials into various containers, iron drums, or plastic drums by weight.

[0003] For small and medium-sized businesses, conventional large-scale automated filling production lines are unnecessary for products such as cup-packaged soy milk, yogurt, and honey. Traditional manual filling methods are also slow and cannot achieve the goal of rapid quantitative filling.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem that conventional large-scale automated filling production lines are not suitable for this purpose, while traditional manual filling methods are slow and cannot achieve rapid quantitative filling, this application provides a precise quantitative liquid filling machine.

[0006] The precise quantitative liquid filling machine provided in this application adopts the following technical solution:

[0007] A precision quantitative liquid filling machine includes a filling barrel, with a feed hopper connected to the top of the filling barrel and a filling tube connected to the bottom of the filling barrel. A filling assembly is disposed inside the filling tube. The filling assembly includes a rotating shaft rotatably disposed on the side wall of the filling tube. One end of the rotating shaft extends into the filling tube and is fixedly connected to a turntable. An eccentric shaft is fixedly installed on the side wall of the turntable. A sliding block is slidably disposed inside the filling tube. The sliding block has a moving groove for the eccentric shaft to slide in. A connecting rod is fixedly installed on the top of the sliding block. A sealing head is fixedly installed on the top of the connecting rod. A drive motor for driving the rotating shaft to rotate is fixedly installed on the outer wall of the filling tube.

[0008] Preferably, the bottom of the sealing head is chamfered.

[0009] Preferably, half the length of the moving groove is greater than the distance from the eccentric shaft to the center of the turntable.

[0010] Preferably, a plurality of support legs are fixedly installed on the bottom outer wall of the filling barrel, and anti-slip pads are fixedly installed on the bottom of the support legs.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] This application utilizes a rotating shaft rotatably connected to the filling tube, along with a turntable, eccentric shaft, sliding block, moving groove, connecting rod, sealing head, and drive motor. By activating the drive motor, the rotating shaft and turntable rotate. The turntable then drives the eccentric shaft to rotate around its axis. As the eccentric shaft rotates, it pushes the sliding block, connecting rod, and sealing head to move up and down, allowing the sealing head to periodically seal the filling tube, thus achieving quantitative filling of the liquid.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a precise quantitative liquid filling machine, referring to... Figure 1-3 The system includes a filling barrel 1, with a feeding hopper 2 connected to the top of the filling barrel 1 and a filling tube 3 connected to the bottom of the filling barrel 1. A filling assembly 4 is provided inside the filling tube 3. The filling assembly 4 includes a rotating shaft 41 rotatably mounted on the side wall of the filling tube 3. One end of the rotating shaft 41 extends into the filling tube 3 and is fixedly connected to a turntable 42. An eccentric shaft 45 is fixedly installed on the side wall of the turntable 42. A sliding block 43 is slidably mounted inside the filling tube 3. A moving groove 44 for the eccentric shaft 45 to slide is opened inside the sliding block 43. A connecting rod 46 is fixedly installed on the top of the sliding block 43. A sealing head 47 is fixedly installed on the top of the connecting rod 46. A drive motor 48 for driving the rotating shaft 41 to rotate is fixedly installed on the outer wall of the filling tube 3.

[0019] Here, by starting the drive motor 48, the drive motor 48 can drive the rotating shaft 41 and the turntable 42 to rotate. The turntable 42 drives the eccentric shaft 45 to rotate around the axis of the turntable 42. When the eccentric shaft 45 rotates, it can push the sliding block 43, the connecting rod 46 and the sealing head 47 to move up and down, so that the sealing head 47 can seal the filling tube 3 at regular intervals, thereby realizing quantitative filling of liquid.

[0020] Reference Figure 3 The bottom of the sealing head 47 is chamfered.

[0021] Here, the bottom of the sealing head 47 is chamfered to facilitate the insertion of the sealing head 47 into the filling tube 3.

[0022] Reference Figure 3 Half the length of the moving groove 44 is greater than the distance from the eccentric shaft 45 to the center of the turntable 42.

[0023] Here, by making half the length of the moving groove 44 greater than the distance from the eccentric shaft 45 to the axis of the turntable 42, the eccentric shaft 45 can rotate around the axis of the turntable 42.

[0024] Reference Figure 1 Multiple support legs are fixedly installed on the bottom outer wall of the filling barrel 1, and anti-slip pads are fixedly installed on the bottom of the support legs.

[0025] The filling barrel 1 is stably supported by the support legs and anti-slip pads.

[0026] The implementation principle of a precise quantitative liquid filling machine according to an embodiment of this application is as follows: When in use, the device is placed in a designated position and the power is turned on. Then, the filling liquid is added into the filling tube 3 through the feed hopper 2. During filling, the drive motor 48 is started. The drive motor 48 can drive the rotating shaft 41 and the turntable 42 to rotate. The turntable 42 drives the eccentric shaft 45 to rotate around the axis of the turntable 42. When the eccentric shaft 45 rotates, it can push the sliding block 43, the connecting rod 46 and the sealing head 47 to move up and down, so that the sealing head 47 can seal the filling tube 3 at regular intervals, thereby realizing quantitative filling of liquid.
