DETAILED DESCRIPTION

[0018] Embodiment 1

[0019] like Figure 1-Figure 3 As shown, a liquid filling device proposed in this embodiment includes a frame 1, a filling mechanism and a conveying assembly, wherein a driving assembly and a limiting frame 7 are arranged on the frame 1; the filling mechanism is arranged on the driving assembly, and the filling mechanism is located above the limiting frame 7, the filling mechanism includes a plurality of filling assemblies 6 arranged side by side on the driving assembly, the filling assembly 6 includes a fixed liquid outlet pipe 61 arranged on the driving assembly, a flow limiting pipe 63 slidably arranged on the fixed liquid outlet pipe 61, a spring 62 whose two ends are respectively connected to the fixed liquid outlet pipe 61 and the top of the flow limiting pipe 63, and a sponge 64 arranged at the bottom end of the fixed liquid outlet pipe 61; the conveying assembly is arranged on the frame 1, and the conveying assembly is located below the limiting frame 7.

[0020] When this embodiment is in use, the conveying assembly conveys a batch of bottles to the bottom of the filling assembly, and the driving assembly drives the multiple fixed liquid outlet pipes 61 to descend until the flow limiting tube 63 abuts against the limiting frame 7 and then descends to a position where it cannot descend. After the flow limiting tube 63 rises relative to the position of the fixed liquid outlet pipe 61, the hand washing liquid in the fixed liquid outlet pipe 61 flows into the bottle at the bottom. When the bottle is full, the driving assembly drives the filling assembly to reset, and the spring 62 pushes the flow limiting tube 63 to descend. When the flow limiting tube 63 descends, the hand washing liquid left on the fixed liquid outlet pipe 61 is squeezed into the bottle. At the same time, the flow limiting tube 63 squeezes the sponge 64 to allow part of the hand washing liquid in the sponge 64 to flow into the bottle, so that the liquid remaining on the fixed liquid outlet pipe 61 cannot drip, thereby avoiding the dripping hand washing liquid affecting the appearance of the product.

[0021] Embodiment 2

[0022] like Figure 1-Figure 3As shown, a liquid perfusion device proposed in this embodiment, compared with the first embodiment, in this embodiment, the fixed liquid outlet pipe 61 has a filling cavity 611 and a liquid outlet channel 612 which are interconnected, the liquid outlet channel 612 and the sponge 64 are both in annular shape, the liquid outlet channel 612 is located at the bottom end of the fixed liquid outlet pipe 61, the bottom of the fixed liquid outlet pipe 61 has a plurality of through holes arranged along a ring, the top of the limiting frame 7 has a limiting channel, the limiting channel is located below the plurality of fixed liquid outlet pipes 61, the limiting channel is rectangular, and the width of the limiting channel is greater than the diameter of the fixed liquid outlet pipe 61.

[0023] The flow-limiting tube 63 includes a limiting ring portion 631, a sliding tube portion 632 and a closed cover portion 633 which are arranged in sequence from top to bottom. The closed cover portion 633 is slidably arranged in the filling cavity 611 and a plurality of through holes. The closed cover portion 633 has a liquid outlet hole 6331, and the diameter of the liquid outlet hole is smaller than the inner diameter of the liquid outlet channel 612. The sliding tube portion 632 has a plurality of ventilation holes 6321 arranged along a ring. When the flow-limiting tube 63 is raised or lowered, the space formed between the sliding tube portion 632 and the fixed liquid outlet tube 61 will change with the sliding position of the sliding tube portion 632. When the space increases or decreases, air will flow in or out through the ventilation holes 6321, so as to avoid the pressure between the flow-limiting tube 63 and the fixed liquid outlet tube 61 being too large or too small when the flow-limiting tube 63 is moved, which makes it difficult to move normally, thereby improving the filling speed of the hand sanitizer.

[0024] In this embodiment, when the bottle moves to a suitable position, the driving assembly drives the fixed liquid outlet pipe 61 to descend, and the fixed liquid outlet pipe 61 continues to descend to a position where the fixed liquid outlet pipe 61 cannot descend when it abuts against the limiting frame 7 at the bottom of the limiting ring portion 631, and the hand sanitizer flows from the filling chamber 611 through the liquid outlet hole 6331 and multiple through holes into the bottle in sequence. When the fixed liquid outlet pipe 61 is reset, the flow limiting pipe 63 descends, and the bottom end of the flow limiting pipe 63 blocks the liquid outlet channel 612, and the sliding tube portion 632 blocks the multiple through holes, thereby reducing the area to which the liquid can adhere and reducing the loss during liquid filling.

[0025] Embodiment 3

[0026] like Figure 1 As shown, a liquid perfusion device proposed in this embodiment, compared with the first embodiment, in this embodiment, the driving assembly includes a motor a2 arranged on the frame 1, a screw rod 3 rotatably arranged on the frame 1 and connected to the output end of the motor a2, two guide rods 4 arranged side by side on the frame 1, and a lifting frame 5 slidably arranged on the two guide rods 4 and threadedly connected to the screw rod 3.

[0027] In this embodiment, when filling hand sanitizer, the motor a2 drives the screw rod 3 to rotate, and the screw rod 3 drives the lifting frame 5 to rise and fall according to the filling needs. After the lifting frame 5 descends to the limit frame 7, it continues to descend until the spring 62 is squeezed to a position where it cannot be squeezed any further. The two guide columns can ensure that the filling mechanism avoids deviation when it is lifted and lowered, thereby reducing the number of maintenance times of the device.

[0028] Embodiment 4

[0029] like Figure 1-Figure 2 As shown, a liquid filling device proposed in this embodiment, compared with the first embodiment, in this embodiment, the conveying assembly includes a motor b8 arranged on a frame 1, a roller a9 and a roller b rotatably arranged on the frame 1, a conveyor belt 10 arranged on the roller a9 and the roller b, two guide blocks 11 arranged opposite to each other on the frame 1, and a roller 12 rotatably arranged on the guide block 11, the motor b8 is drivingly connected to the roller a9, and the distance between the top end of the guide block 11 and the bottom end of the frame 1 is consistent with the distance between the top end of the conveyor belt 10 and the bottom end of the frame 1.

[0030] In this embodiment, after multiple bottles are conveyed to the guide block 11 in batches, multiple rollers 12 reduce the friction between the bottles and the guide block 11 during movement, and the motor b8 intermittently drives the roller a9 to rotate, and the roller a9 drives the roller b to rotate through conveying. After a batch of bottles moves to the bottom of the filling mechanism, after the bottle filling is completed and the hand sanitizer will not drip on the filling mechanism, the motor b8 starts to move the next batch of bottles to the bottom of the filling mechanism, thereby reducing the probability of hand sanitizer dripping onto the bottles.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
