Description

Technical Field

[0001] This utility model belongs to the field of liquid filling technology, and specifically relates to a liquid filling device. Background Technology

[0002] Liquid filling equipment is an automated production line used to quantitatively inject liquid products such as beverages, pharmaceuticals, chemical solutions, lubricants, and detergents into containers such as bottles, bags, and drums. This type of equipment is widely used in automated packaging production lines in the food, pharmaceutical, daily chemical, and fine chemical industries. Its main components typically include a liquid supply system, a metering mechanism, a filling head, a conveying device, a control unit, and a bottle level detection mechanism.

[0003] Liquid filling equipment typically dispenses liquid automatically according to a set capacity or liquid level and introduces the fluid through a filling nozzle. It is required to avoid problems such as liquid splashing, dripping, and foam residue while maintaining high efficiency, high cleanliness, and high precision. However, during the liquid filling process, especially in scenarios involving high-viscosity liquids or foamy liquids, residual liquid may drip or remain on the nozzle after the filling head is closed. This residual liquid may drip onto the outside of the bottle or onto the conveyor track, causing contamination of the container surface, product defects, and even affecting subsequent capping processes. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a liquid filling device that solves the problem of residual liquid dripping or liquid hanging at the nozzle after the filling head is closed during the liquid filling process, especially in the filling scenarios of high viscosity liquids or foamy liquids. These residual liquids may drip onto the outside of the bottle mouth or the conveying track, causing container surface contamination, product defects, and even affecting the subsequent capping process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a liquid filling device, comprising a support rod, an electric telescopic rod one being provided on the upper side of one end of the support rod, an installation plate being fixedly provided on the upper end of the electric telescopic rod one, a central guide cavity being fixedly provided on the lower side of the support rod away from the electric telescopic rod one, a guide sleeve being fixedly connected to the upper side of the central guide cavity, the guide sleeve penetrating to the upper side of the support rod and connecting to an electric telescopic rod two, the electric telescopic rod two being fixedly provided on the upper end of the guide sleeve, a filling tube being fixedly connected to the center of the lower side of the central guide cavity, and a shut-off valve core being fixedly connected to the output end of the electric telescopic rod two through the guide sleeve to the inner side of the central guide cavity, the diameter of the shut-off valve core being larger than the inner diameter of the filling tube, the central guide... A liquid inlet is fixedly connected to the upper side of the cavity. The input end of the liquid inlet is connected to a liquid inlet pipe. A drip absorption head is provided at the lower end of the filling pipe. A honeycomb pore adsorption liner is fixedly provided inside the drip absorption head. A connection port is provided on the side of the honeycomb pore adsorption liner, extending to the outside of the drip absorption head. A micro air pump is fixedly provided on the side of the central guide cavity. An air guide pipe is provided between the output end of the micro air pump and the connection port. The upper and lower sides of the inner surface of the honeycomb pore adsorption liner are both shoe uppers that converge towards the central axis. Honeycomb pores are evenly opened on the inner surface of the honeycomb pore adsorption liner. A cavity is opened on the inner side of the honeycomb pore adsorption liner. The honeycomb pores and the cavity are connected. The connection port is connected to the cavity.

[0006] The beneficial effects of this invention are as follows: When the liquid flows to the lower end of the filling tube, it will pass through the honeycomb pores to absorb the inner side of the liner. First, it will be buffered by the upper inclined area and then naturally absorbed by the honeycomb pores. There is not much residual liquid. After being absorbed by the honeycomb pores on the inner wall of the filling tube, it is difficult for the liquid to flow down through the honeycomb pores to absorb the liner. Thus, the problem of residual liquid dripping or liquid hanging at the tube opening is effectively solved, and residual liquid is prevented from dripping onto the outside of the bottle opening or the conveying track, preventing contamination of the container surface and avoiding affecting the subsequent capping process.

[0007] To allow for quick replacement of the drip absorption head;

[0008] As a further improvement to the above technical solution: the drip absorption head is threadedly connected to the lower end of the filling tube.

[0009] The beneficial effect of this improvement is that it enables quick replacement of the droplet absorption head.

[0010] To prevent liquid from leaking along the interface gaps;

[0011] As a further improvement to the above technical solution: a sealing pressure ring is crimped between the drip absorption head and the filling tube.

[0012] The beneficial effect of this improvement is to prevent liquid leakage along the interface gap.

[0013] To facilitate disassembly and cleaning of the central flow guide cavity and lower structure;

[0014] As a further improvement to the above technical solution: a hexagonal connector is threaded between the liquid inlet and the liquid inlet pipe, and a rotary connector is threaded on the lower side of the electric telescopic rod, with the lower side of the rotary connector being rotatably connected to the support rod.

[0015] The beneficial effects of this improvement are: it facilitates the disassembly and cleaning of the lower central guide cavity and the lower structure.

[0016] For use in observing the internal situation;

[0017] As a further improvement to the above technical solution: the central flow guiding cavity is made of transparent material.

[0018] The beneficial effect of this improvement is that it can be used to observe internal conditions.

[0019] To increase the stability of the connection between the inlet pipe and the inlet port;

[0020] As a further improvement to the above technical solution: a fixing plate is symmetrically fixed on both sides of the liquid inlet pipe on the lower side of the support rod away from the central guide cavity. Bolts are threaded to the opposite sides of the fixing plates. Each bolt passes through the fixing plate and is rotatably connected to a clamping block. The clamping blocks are clamped on both sides of the liquid inlet pipe.

[0021] The beneficial effect of this improvement is that it increases the stability of the connection between the inlet pipe and the inlet port.

[0022] In order to quickly intercept the flow and form a stable closed interface;

[0023] As a further improvement to the above technical solution: the lower end of the shut-off valve core has a plunger-type structure, and the lower end of the shut-off valve core is tightly inserted into the upper end of the filling tube.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] like Figure 1 — Figure 4As shown: A liquid filling device includes a support rod 1. An electric telescopic rod 2 is mounted on the upper side of one end of the support rod 1. An mounting plate 21 is fixedly mounted on the upper end of the electric telescopic rod 2. A central flow guiding cavity 3 is fixedly mounted on the lower side of the support rod 1, away from the electric telescopic rod 2. A guide sleeve 4 is fixedly connected to the upper side of the central flow guiding cavity 3. The guide sleeve 4 extends through to the upper side of the support rod 1 and connects to an electric telescopic rod 5. The electric telescopic rod 5 is fixedly mounted on the upper end of the guide sleeve 4. A filling tube 6 is fixedly connected to the center of the lower side of the central flow guiding cavity 3. The output end of the electric telescopic rod 5 extends through the guide sleeve 4 and is fixedly connected to a shut-off valve core 7 inside the central flow guiding cavity 3. The diameter of the shut-off valve core 7 is larger than that of the filling tube 6. The inner diameter of the central guide cavity 3 is as follows: A liquid inlet 8 is fixedly connected to the upper side of the central guide cavity 3; a liquid inlet pipe 9 is connected to the input end of the liquid inlet 8; a drip absorption head 10 is provided at the lower end of the filling pipe 6; a honeycomb-hole adsorption liner 101 is fixedly lined inside the drip absorption head 10; a connection port 103 is connected to the side of the honeycomb-hole adsorption liner 101, extending to the outside of the drip absorption head 10; a micro air pump 105 is fixedly installed on the side of the central guide cavity 3; an air guide pipe 104 is connected between the output end of the micro air pump 105 and the connection port 103; the upper and lower sides of the inner surface of the honeycomb-hole adsorption liner 101 are both shoe uppers that converge towards the central axis; the honeycomb-hole adsorption liner 101... The inner surface of the filling tube 6 is uniformly provided with honeycomb holes. The honeycomb holes and the inner surface of the adsorption liner 101 have cavities. The honeycomb holes and the cavities are connected, as is the connection port 103. When liquid flows to the lower end of the filling tube 6, it passes through the inner surface of the honeycomb adsorption liner 101, is buffered by the upper inclined area, and is naturally adsorbed by the honeycomb holes. The residual liquid is minimal. After being adsorbed by the honeycomb holes on the inner wall of the filling tube 6, it is difficult for the liquid to flow down through the honeycomb adsorption liner 101. This effectively solves the problem of residual liquid dripping or liquid clinging to the tube opening, preventing residual liquid from dripping onto the outside of the bottle opening or the conveying track, thus preventing container surface contamination and avoiding impact on subsequent capping processes. The drip absorption head 10 is threadedly connected to the lower end of the filling tube 6, enabling the drip absorption head 10 to... For quick replacement, a sealing ring 102 is crimped between the drip absorption head 10 and the filling tube 6 to prevent liquid leakage along the interface gap. A hexagonal connector is threaded between the inlet 8 and the inlet tube 9. A rotating connector is threaded onto the lower side of the electric telescopic rod 2. The lower side of the rotating connector is rotatably connected to the support rod 1, facilitating the disassembly and cleaning of the central guide cavity 3 and the lower structure. The central guide cavity 3 is made of transparent material for observing the internal condition. A fixing plate 91 is symmetrically fixed on both sides of the inlet tube 9 on the lower side of the support rod 1 away from the central guide cavity 3. Bolts 92 are threaded onto the opposite sides of the fixing plates 91, and each bolt 92 passes through the fixing plate 91 and is rotatably connected to a clamping block 93.The clamping blocks 93 are positioned on both sides of the inlet pipe 9 to increase the stability of the connection between the inlet pipe 9 and the inlet port 8. The lower end of the shut-off valve core 7 has a plunger-type structure, and the lower end of the shut-off valve core 7 is tightly inserted into the upper end of the filling pipe 6, which can achieve rapid interception and form a stable closed interface to prevent residual liquid leakage.

[0033] Working principle and usage process of this utility model:

[0034] In use, this device is fixedly installed on the filling line via mounting plate 21 and connected to the liquid supply source via inlet pipe 9. During filling, sensors corresponding to this device are distributed along the filling line and are integrated into the PLC control system. When the sensor detects the arrival of the container, the output end of electric telescopic rod 2 pushes down the support rod 1. The support rod 1 drives the filling tube 6 through the central guide cavity 3, pushing the filling tube 6 into the container opening. The liquid supply source supplies liquid to the inlet pipe 9, which then enters the central guide cavity 3 through the inlet 8, and then fills the container through the lower filling tube 6. After filling is complete, the output end of electric telescopic rod 5 pushes down the shut-off valve core 7, which blocks the upper inlet of the filling tube 6. At this time, liquid remains on the inner wall of the filling tube 6 and flows downward along the inner wall of the filling tube 6. When the liquid flows to the lower end of the filling tube 6, it will pass through... The inner side of the honeycomb adsorption liner 101 is first buffered by the upper inclined area and then naturally adsorbed by the honeycomb holes, leaving little residual liquid. After being adsorbed by the honeycomb holes on the inner wall of the filling tube 6, it is difficult for the residual liquid to flow down through the honeycomb adsorption liner 101. The lower second inclined surface of the honeycomb adsorption liner 101 is generally used as a tail buffer to increase the difficulty of residual liquid flowing out. In addition, during the filling process, the micro air pump 105 blows air into the honeycomb adsorption liner 101 through the air guide tube 104 and the connection port 103 to ensure that the liquid in the honeycomb holes is blown out. After filling is completed, the micro air pump 105 stops at the same time to ensure that the honeycomb holes can absorb and retain residual liquid, thereby effectively solving the problem of residual liquid dripping or liquid hanging at the tube opening, preventing residual liquid from dripping onto the outside of the bottle opening or the conveying track, preventing contamination of the container surface, and avoiding affecting the subsequent capping process.
