Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to an automatic liquid filling packaging machine. Background Technology

[0002] An automatic filling and packaging machine is a machine that fills materials into a packaging container in a predetermined amount. When packaging liquid products, the liquid needs to be put into the hopper of the packaging machine. After the liquid enters the packaging bag from the hopper, the packaging bag is sealed to complete the packaging of the product.

[0003] Automatic filling and packaging machines inject liquid into packaging bags in a quantitative manner through a quantitative filling device. Before entering the packaging bag, the liquid passes through a discharge pipe. After entering the packaging bag, some liquid remains in the discharge head and drips onto the device along the discharge pipe, causing contamination to the surface of the device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic liquid filling and packaging machine that can squeeze the infusion tube used to fill the packaging bag with liquid in the packaging machine, squeezing the residual liquid into the packaging bag, and avoiding the residue in the discharge head and dripping onto the device along the discharge tube.

[0005] To achieve the above objectives, an automatic liquid filling and packaging machine is provided, comprising a packaging machine body, on which a liquid storage mechanism and a filling mechanism are installed. The filling mechanism is connected to the lower outlet of the liquid storage mechanism. A support frame is fixedly connected to the outer end of the liquid storage mechanism, and support rods are fixedly connected to the four corners of the lower end of the support frame. The packaging machine body and the filling mechanism are fixed by the support rods. This machine can squeeze the liquid delivery tube used to fill the packaging bag with liquid, forcing any residual liquid into the packaging bag, preventing it from remaining in the outlet head and dripping onto the device along the outlet tube.

[0006] According to the aforementioned automatic liquid filling and packaging machine, the filling mechanism comprises a base plate, a guide frame, an extrusion mechanism, a drive motor, and a liquid storage cylinder. The base plate is fixedly connected to a support rod, and the liquid storage cylinder is fixedly connected to the bottom of the liquid storage mechanism. The inlet of the liquid storage cylinder is connected to the outlet of the liquid storage mechanism. The inlet of the liquid storage cylinder is located at one end of the liquid storage cylinder. A pusher piston is slidably connected inside the liquid storage cylinder. A pusher piston rod is installed at the end of the pusher piston away from the inlet, and the pusher piston rod passes through the liquid storage cylinder and is slidably connected to the liquid storage cylinder. The end of the pusher piston rod passing through the liquid storage cylinder is fixed. A connecting plate is connected, with a first connecting rod rotatably connected to one side of the connecting plate. A second connecting rod is rotatably connected to the end of the first connecting rod away from the connecting plate. A guide frame and a drive motor are fixedly connected to the upper end of the base plate. The first connecting rod passes through the guide frame and is slidably connected to it. The shaft of the drive motor is fixedly connected to a connecting rod for rotatably connecting the end of the second connecting rod away from the first connecting rod. A flexible tube for filling liquid is fixedly connected to the end of the liquid storage cylinder away from the connecting plate, and the flexible tube passes downward through the base plate. Two extrusion mechanisms are provided and symmetrically fixedly connected to the lower end of the base plate. The drive motor, the first connecting rod, the second connecting rod, and the guide frame combine to form a reciprocating motion mechanism, which drives the pusher piston to move in the liquid storage cylinder, thereby quantitatively drawing liquid from the liquid storage mechanism into the liquid storage cylinder and then delivering the liquid to the packaging bag through the flexible tube.

[0007] According to the aforementioned automatic liquid filling and packaging machine, the liquid storage mechanism comprises a liquid storage tank, a stirring paddle, a drive shaft, and a stirring motor. The liquid storage tank passes through a support frame and is fixedly connected to it. An inlet is located at the upper end of the liquid storage tank. The stirring motor is fixedly connected to the middle of the upper end of the liquid storage tank, and its rotating shaft extends downward into the liquid storage tank. The drive shaft is fixedly connected to the lower end of the stirring motor's rotating shaft and is located in the middle of the liquid storage tank, rotatably connected to it. The stirring paddle is fixedly connected to the outside of the drive shaft, and the drive shaft passes through the middle of the stirring paddle. The bottom of the liquid storage tank communicates with the inlet of the liquid storage cylinder. The stirring motor drives the stirring paddle to rotate via the drive shaft, stirring the liquid and preventing stratification after sedimentation in the liquid storage tank.

[0008] According to the aforementioned automatic liquid filling and packaging machine, the extrusion mechanism comprises a fixed plate, a mounting plate, an extrusion block, a spring, and an electric push rod. The fixed plate is fixedly connected to the lower end of the base plate. The mounting plate has a U-shaped structure and is located on the side of the fixed plate facing the hose. The extrusion block is an inverted prism with a right-angled triangular cross-section, and the inclined surface of the extrusion block faces the hose. The electric push rod is fixedly connected to the middle of the end of the fixed plate away from the mounting plate, and the pushing piston rod of the electric push rod passes through the fixed plate and is slidably connected to the fixed plate. The pushing piston rod of the electric push rod is fixedly connected to the mounting plate. The extrusion block is located in the mounting plate, and both ends of the extrusion block are rotatably connected to the mounting plate. A connector is rotatably connected to the middle of the side of the extrusion block facing the mounting plate. The spring is fixedly connected to the end of the connector away from the extrusion block, and the other end of the spring is fixedly connected to the mounting plate. The electric push rod moves the mounting plate, causing the extrusion block to approach and squeeze the hose. The spring causes the extrusion blocks in the two extrusion mechanisms to gradually press their inclined surfaces together as they squeeze the hose, thereby gradually squeezing the liquid in the hose downwards.

[0009] According to the aforementioned automatic liquid filling and packaging machine, a controller is installed at the bottom of the main body of the packaging machine. The controller controls the device.

[0010] According to the aforementioned automatic liquid filling and packaging machine, one-way valves are installed between the inlet of the liquid storage cylinder and the liquid storage tank, and between the liquid storage cylinder and the hose. The one-way valves ensure that the liquid entering the liquid storage cylinder from the liquid storage tank and the liquid entering the hose from the liquid storage cylinder can only flow in one direction.

[0011] The above solution has the following advantages: the liquid to be filled is stored in the liquid storage mechanism, the liquid injection mechanism extracts a certain amount of liquid from the liquid storage mechanism and injects it into the packaging bag for filling, and the extrusion mechanism in the injection mechanism squeezes the hose on the output injection mechanism to squeeze the residual liquid in the hose into the packaging bag, thus preventing the residual liquid from dripping onto the device through the discharge head.
