Description

Technical Field

[0001] The invention relates to the technical field of liquid beverage defoaming, and in particular to a liquid beverage filling and defoaming device. Background Art

[0002] Liquid beverages refer to beverages that have no definite shape and are easy to flow, with a solid content of about 5%. Liquid beverages are usually consumed by drinking (usually without chewing), such as water, tea, coffee, milk, juice, etc. Liquid beverages can provide a variety of nutrients, including carbohydrates, proteins, antioxidants, water, vitamins and minerals, etc. These ingredients are essential for human survival, growth and reproduction. In addition, liquid beverages do not add any preservatives or chemical ingredients during the production process, which is safer and healthier.

[0003] Existing liquid beverages will produce bubbles or foam during filling. The foam will occupy the space originally used to fill the liquid beverage, resulting in a reduction in the actual amount of liquid filled, thereby affecting production efficiency and output. At the same time, foam overflow will pollute the production environment, increase cleaning costs, and may even cause production accidents. In addition, the foam entering the final product will affect the quality and taste of the product. The existing liquid beverage defoaming device has the following shortcomings: 1. The height of the filling tube cannot be adjusted. The filling tube is directly poured into the beverage packaging bottle, which will also produce foam due to the impact between the beverage and the bottom of the bottle.

[0016] Beneficial effects of the present invention: 1. The present invention designs a pushing mechanism, namely a guide rod and a pushing assembly, through which the filling tube is first extended into the inner bottom of the beverage packaging bottle to reduce the filling height, and then the beverage is filled from bottom to top at a uniform speed. In this way, the air in the packaging bottle can be expelled first, reducing the chance of contact between the beverage and the air, thereby reducing the generation of bubbles.

[0017] 2. The present invention designs a switching mechanism, namely a traction component, a delivery pipe, a plurality of discharge pipes, a plurality of storage tanks and a plurality of stirring components. By designing a plurality of storage tanks, different types of defoaming agents are stored, and the liquid metering pump can accurately control the amount of defoaming agent delivered to the temporary storage cylinder. On the one hand, the corresponding defoaming agent can be selected according to different types of beverages to improve the targeted defoaming. On the other hand, it can meet the defoaming agent content required for filling different types of liquid beverages, thereby meeting different defoaming needs and improving the flexibility and practicality of the device.

[0018] 3. The present invention can realize the sequential linkage of the pushing mechanism, the injection mechanism and the switching mechanism by designing the transmission component and the traction component, that is, when the filling tube vertically descends to enter the packaging bottle, the extrusion rod in the temporary storage cylinder is synchronously driven to rise vertically to provide a storage space for the defoaming agent to be input, and when the extrusion rod rises vertically, the defoaming agent in the storage tank is synchronously driven to stir, so as to ensure that the defoaming agent is evenly distributed after being injected into the packaging bottle, and the fusion effect with the beverage is improved, thereby improving the defoaming effect. If the defoaming agent is not stirred, it will settle at the bottom of the liquid or float unevenly on the surface of the liquid, thereby reducing the defoaming effect. After the extrusion rod rises vertically into place , the storage tank inputs the corresponding defoaming agent into the temporary storage cylinder through the conveying pipe, then starts the filling equipment first, injects the beverage into the packaging bottle through the telescopic tube and the filling tube, and then drives the output end of the electric push rod to shrink through the controller, so that the filling tube is driven to rise vertically at a uniform speed through the push block, that is, the filling tube is raised while filling the beverage, which can avoid contamination caused by contact between the filling tube and the beverage. While the filling tube rises vertically, the extrusion rod synchronously descends vertically, so that the defoaming agent previously injected into the temporary storage cylinder is squeezed into the filling tube through the injection tube. By synchronously injecting the defoaming agent, the generation of foam in the beverage can be suppressed, and the generated foam can be helped to quickly break and disappear, further improving the defoaming effect.

[0019] 4. Combining the beneficial effects of 1 and 3, by shortening the filling height and adding defoaming agent, a double defoaming effect can be achieved, further improving the defoaming effect of the device.

[0020] 5. The present invention can realize the sequential linkage of the pushing mechanism, the injection mechanism and the switching mechanism by designing the transmission component and the traction component, thereby reducing the number of driving sources used in the device, reducing the defoaming cost, and at the same time reducing the overall structure of the device, reducing the manufacturing cost and the occupied space. With the installation plate, the device can be easily connected to the existing filling equipment, improving the effect of supporting use, and further improving the practicality of the device.

[0037] When the extrusion rod 24 rises vertically into position inside the temporary storage tube 8, the liquid metering pump 39 on one of the storage tanks 11 is turned on, so that the stirred defoaming agent in the storage tank 11 enters the interior of the temporary storage tube 8 through the discharge pipe 10, the connecting pipe 12 and the delivery pipe 9 in turn. Several storage tanks 11 are designed to store different types of defoaming agents, and the liquid metering pump 39 can accurately control the amount of defoaming agent delivered to the temporary storage tube 8. By designing the above structure, on the one hand, corresponding defoaming agents can be selected according to different types of beverages to improve the targeted defoaming. On the other hand, it can meet the defoaming agent content required for filling different types of liquid beverages, thereby meeting different defoaming needs, and improving the flexibility and practicality of the device. When the delivery pipe 9 adds a suitable amount of defoaming agent to the interior of the temporary storage tube 8, first The filling equipment is started, so that the liquid beverage is transported to the filling tube 3 through the telescopic tube 2, and the filling begins. The controller then drives the output end of the electric push rod 13 to contract, so that the filling tube 3 is driven to rise at a uniform speed at the inner bottom of the packaging bottle through the push block 14, that is, the filling tube 3 rises while filling the liquid beverage. In this way, the air in the packaging bottle can be expelled first, reducing the chance of contact between the beverage and the air, thereby reducing the generation of bubbles. Since the pushing mechanism and the injection mechanism are linked by the transmission assembly, while the beverage is being filled, the extrusion rod 24 descends vertically inside the temporary storage tube 8, and the previously injected defoaming agent is synchronously transported from the injection tube 7 to the inside of the filling tube 3. While filling, the defoaming agent is injected synchronously, which can inhibit the generation of foam and help the generated foam to quickly break and disappear, further improving the defoaming effect.

Since the second driving wheel 32 is fixedly connected to the second rotating shaft 31, the second driven wheel 33 and the first bevel gear 35 are respectively fixedly connected to the two ends of the first hinge shaft, the second bevel gear 36 is fixedly connected to one of the stirring shafts 26, the first bevel gear 35 and the second bevel gear 36 are meshed, and the second driving wheel 32 and the second driven wheel 33 are sleeved by the second belt 34, thereby driving one of the stirring shafts 26 to rotate clockwise. Since the top of each stirring shaft 26 is fixedly connected to a synchronous wheel 37, several synchronous wheels 37 are sleeved by the synchronous belt 38, thereby driving the other two stirring shafts 26 to rotate clockwise.

[0039] When the stirring shaft 26 rotates clockwise, since the stirring shaft 26 is rotatably connected to the storage tank 11 through the bearing, several pipe clamps 27 are fixedly connected to the outer wall of the stirring shaft 26, and every two stirring plates 28 are fixedly connected to the outer wall of a pipe clamp 27, so that when the extrusion rod 24 rises vertically inside the temporary storage tube 8, the defoaming agent in the storage tank 11 is synchronously stirred to ensure that it is evenly distributed after being injected into the packaging bottle, thereby improving the fusion effect with the beverage and the defoaming effect. If no stirring is performed, the defoaming agent will settle at the bottom of the liquid or float unevenly on the surface of the liquid, thereby reducing the defoaming effect.

[0040] The first one-way valve 40 ensures that the defoaming agent entering the temporary storage cylinder 8 will not flow back into the delivery tube 9 when squeezed by the squeezing rod 24, thereby ensuring the defoaming effect on the liquid beverage.

[0041] The second one-way valve 41 ensures that the defoaming agent entering the temporary storage cylinder 8 will enter the injection pipe 7 only after being squeezed by the squeezing rod 24 .

[0042] Since the injection mechanism and the switching mechanism operate in conjunction with the traction assembly, while the extrusion rod 24 squeezes the defoaming agent previously input into the temporary storage cylinder 8 into the filling tube 3, the traction assembly drives the three stirring shafts 26 to reverse, thereby realizing the forward and reverse rotation of the stirring assembly, further improving the stirring effect of the defoaming agent.
