Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a filling machine. Background Technology

[0002] In the food production field, filling machines are an indispensable key piece of equipment for the production of liquid food packaging. Especially in the liquid filling process of condiments, the conveying device accurately transports the filling containers of different volumes to be filled to the bottom of the filling machine. Then, the filling nozzle of the filling machine accurately fills the liquid into the filling container according to the set capacity or weight, completing the liquid filling process. This greatly improves the efficiency and quality of condiment production and realizes the automated connection from production to packaging.

[0003] However, most filling machines on the market have several defects in actual processing: First, most of the filling nozzles on the filling mechanism can only adapt to a single type of beverage container.

[0033] See Figures 1 to 3As shown, a filling machine of this utility model includes a mounting platform 1, a filling seat 3, a filling cylinder 5, an exhaust pipe 7, and a feeding channel 8; wherein,

[0034] The filling base 3 is located below the mounting platform 1 and is slidably connected to the mounting platform 1. A filling platform 4 is fixed inside the filling base 3, and the longitudinal section of the filling platform 4 is trapezoidal. The filling cylinder 5 is a hollow cylindrical structure. One end of it passes longitudinally through the mounting platform 1 and is fixedly connected to the mounting platform 1, while the other end is arranged close to the filling base 3. The exhaust pipe 7 is arranged longitudinally inside the filling cylinder 5, and the end away from the filling base 3 extends through the filling cylinder 5 to the outside of the filling cylinder 5. The feed channel 8 is located between the outer wall of the exhaust pipe 7 and the inner wall of the filling cylinder 5. The end of it close to the filling base 3 is the discharge port, and the discharge port is provided with an oblique opening 9. The other end extends through the filling cylinder 5 to the outside of the filling cylinder 5.

[0035] Specifically, a square channel for fixing is provided on one side of the mounting platform 1. This square channel is fitted onto the lifting mechanism 2 of the filling conveying device, allowing the filling machine to rise and fall with the lifting mechanism 2, achieving automatic integration. A platform is horizontally connected to the square channel for fixing the filling cylinder 5. The filling cylinder 5 is a longitudinally arranged hollow cylindrical structure. An exhaust pipe 7 is longitudinally arranged inside the filling cylinder 5. One end of the exhaust pipe 7 passes through the filling cylinder 5 and extends to the outside of the filling cylinder 5, connecting to a vacuum device. This is used to evacuate the air from the filling container before filling, or to evacuate while filling, improving filling quality. The other end of the exhaust pipe 7 extends to the discharge port. The filling seat 3 is located below the mounting platform 1 and is slidably connected to the mounting platform 1, allowing the filling seat 3 to adapt to filling containers of different heights. The filling seat 3 is internally threaded to the filling platform 4, facilitating the replacement and maintenance of the filling platform 4. The filling platform 4 has a trapezoidal longitudinal section, thus accommodating filling containers with different sized filling nozzles. A feeding channel 8 is provided between the outer wall of the exhaust pipe 7 and the inner wall of the filling cylinder 5. One end of the feeding channel 8 contacts the filling container, close to the filling seat 3, and has a discharge port. The discharge port is angled 9 to accommodate the filling of liquids of different concentrations and to prevent blockage at the discharge port due to high viscosity of the filling liquid. The other end of the feeding channel 8 extends through the filling cylinder 5 to the outside of the filling cylinder 5 and is connected to an external material conveying device through the feeding pipe 6.

[0036] In this embodiment, by designing the longitudinal section of the discharge port as a trapezoid, the filling machine can adapt to filling containers with different sizes of filling nozzles. The angled design 9 at the discharge port allows the filling machine to adapt to the filling needs of liquids with different concentrations, preventing clogging due to excessive concentration and ensuring a smooth filling process, significantly improving filling efficiency and equipment reliability. Furthermore, the sliding connection between the filling base 3 and the mounting platform 1 allows the filling machine to adapt to filling containers of different heights without changing the filling nozzle, achieving compatibility with filling containers of various heights and sizes, greatly expanding the applicability of the filling machine and enhancing its versatility and flexibility.

[0037] Furthermore, a square channel for fixing is provided on one side of the mounting platform 1. The cross-sectional dimensions of this square channel are 80mm×80mm-120mm×120mm, and the inner wall is provided with strip-shaped reinforcing ribs along the length direction, with a thickness of 5mm-8mm, to enhance the load-bearing strength of the square channel. The square channel is fitted onto the lifting mechanism 2 of the filling and conveying device and fixed to the lifting mechanism 2 with an M10-M12 bolt, ensuring a stable connection. This allows the filling machine to achieve precise lifting within a range of 0-500mm following the lifting mechanism 2, meeting the needs of automated integrated production. The square channel is horizontally integrated with a platform, which is 10mm-15mm thick. The connection between the platform and the square channel is provided with triangular reinforcing devices, with 2-3 reinforcing devices, further enhancing the load-bearing capacity of the platform. This platform is specifically used to fix the filling cylinder 5, ensuring that the filling cylinder 5 does not shake during operation.

[0038] Furthermore, the filling cylinder 5 is a longitudinally arranged hollow cylindrical structure with an inner diameter of 80mm-120mm and a length of 300mm-500mm. The cylinder wall is made of stainless steel, which has good corrosion resistance. An exhaust pipe 7 is longitudinally arranged inside the filling cylinder 5. The exhaust pipe 7 has an outer diameter of 15mm-25mm. One end of the exhaust pipe passes through the top of the filling cylinder 5 and extends 100mm-150mm outside the cylinder. It is connected to a vacuum device via a flange, and a high-pressure resistant sealing gasket is installed between the flanges. This is used to evacuate the air from the filling container before filling, or to evacuate while filling, effectively preventing material oxidation and improving filling quality. The other end of the exhaust pipe 7 extends to the discharge port, 5mm-10mm away from the discharge port end face, ensuring complete venting.

[0039] In some specific embodiments of this utility model, the mounting platform 1 and the filling seat 3 are connected and fixed by a limiting rod 11. One end of the limiting rod 11 passes through the mounting platform 1 and is fixed to the mounting platform 1 by bolts; the other end of the limiting rod 11 passes through the filling seat 3 and is fixed to the mounting platform 1 by bolts; a buffer spring 12 is fitted on the limiting rod 11 and arranged between the mounting platform 1 and the filling seat 3.

[0040] In this embodiment, the limiting rod 11 is used to control the vertical up-and-down movement of the filling seat 3 and the filling platform 4, ensuring that the discharge port is directly facing the filling container during the filling process. Simultaneously, the limiting rod 11 and the buffer spring 12 provide stable buffer support, reducing the impact of equipment vibration on filling accuracy and ensuring a smooth filling process. The mounting platform 1 and the filling seat 3 are connected and fixed via the limiting rod 11, further improving the stability and safety of the filling machine. The limiting rod 11 has a diameter of 12mm-16mm and a length of 200mm-300mm. One end of the limiting rod 11 passes through a 13mm-17mm diameter through hole in the mounting platform 1, with a guide sleeve inside to ensure that the limiting rod 11 moves up and down without jamming. This end is threaded and fixed to the mounting platform 1 with matching hexagonal bolts, and a spring washer is provided to prevent loosening due to long-term vibration. The other end of the limiting rod 11 passes through the corresponding through hole of the filling seat 3, and is fixed to the filling seat 3 by bolts with the same bolt specifications, in conjunction with the guide sleeve and machined external threads. A 3mm-5mm rubber shock-absorbing pad is provided between the bolt head at the bottom of the filling seat 3 and the filling seat 3 to reduce the rigid impact between the bolt and the filling seat 3. A buffer spring 12 is fitted on the limiting rod 11. The buffer spring 12 is a cylindrical helical spring, supported by spring steel wire coils with a diameter of 2mm-3mm, a free length of 80mm-120mm, and 5-8 working turns. Both ends are smoothed to ensure uniform force distribution. The buffer spring 12 is arranged between the bottom of the mounting platform 1 and the top of the filling seat 3. Its pre-compression is 1 / 3 of its free length. When the filling seat 3 rises and falls with the lifting mechanism 2 or is impacted by materials, the buffer spring 12 can absorb 50%-70% of the impact force through elastic deformation to ensure the stability of the filling seat 3.

[0041] Moreover, there are two limit rods 11, which are coaxial with the filling cylinder 5 and symmetrically installed on both sides of the filling cylinder 5, connecting the mounting platform 1 and the filling seat 3.

[0042] Furthermore, a limiting seat 13 is provided on the limiting rod 11, and the lower ends of the two limiting seats 13 are fixedly connected to the mounting platform 1 for fixing and locking.

[0043] In some specific embodiments of this utility model, a dust cover is provided on the outside of the buffer spring 12. The dust cover has a corrugated tube structure, with one end fixed to the mounting platform 1 and the other end fixed to the filling seat 3. The extension and contraction of the dust cover is not less than the maximum compression of the buffer spring 12.

[0044] In this embodiment, the corrugated pipe of the dust cover has a corrugation pitch of 8mm-12mm and a corrugation depth of 5mm-8mm, ensuring sufficient deformation space during expansion and contraction. One end of the dust cover is fixedly connected to the raised ring at the bottom of the mounting platform 1 by an annular clamp. The clamp is made of stainless steel and has a width of 8mm-10mm. It is tightened with bolts to ensure a tight fit without gaps. The other end is fixed to the raised ring at the top of the filling seat 3 by an annular clamp of the same specification. Both clamps have rubber gaskets with a thickness of 1mm-2mm on the inner side to further enhance the sealing and prevent dust or moisture from entering from the connection gap. The dust cover is 5mm-10mm longer than the free length of the buffer spring 12 in its natural state, and its maximum extension / extension is 10%-20% greater than the maximum compression of the buffer spring 12. For example, when the maximum compression of the buffer spring 12 is 50mm, the maximum extension / extension of the dust cover can reach 55mm-60mm, ensuring that the dust cover can still completely enclose the spring when the buffer spring 12 is fully compressed, preventing damage due to excessive stretching. In addition, the inner wall of the dust cover is smooth, leaving a 1mm-2mm gap between it and the buffer spring 12 to avoid friction between the two during extension / extension and reduce wear.

[0045] In some specific embodiments of this utility model, the inclination angle of the bevel 9 is 30°-60°, the edge of the bevel 9 is provided with an arc transition part, the radius of the arc transition part is 1mm-2mm; the inner side of the bevel 9 is provided with a guide rib, the guide rib extends along the material flow direction, and the height of the guide rib is 0.5mm-1mm.

[0046] In this embodiment, the inclined angle of the bevel 9 is 30°-60°, and it is located at the outlet end of the feed channel 8. It has a smooth inclined surface structure and forms a corresponding angle with the axis of the feed channel 8. The edge of the bevel 9 has a rounded transition section with a radius of 1mm-2mm. The rounded transition section, the bevel 9, and the outer wall of the feed channel 8 are integrally ground and formed without obvious seams. The inner side of the bevel 9 has guide ribs extending along the material flow direction. There are 3-5 guide ribs, evenly distributed along the width of the bevel 9, with a distance of 5mm-8mm between adjacent ribs. The guide ribs are fixed to the inner wall of the bevel 9 by welding or integral forming. The material is the same as that of the feed channel 8, and the height is 0.5mm-1mm. The top is rounded and smoothly transitions to the surface of the bevel 9.

[0047] In some specific embodiments of this utility model, a plurality of gaskets 10 are arranged on the side of the filling cylinder 5 near the discharge port, and a limiting plate is provided on the upper surface of the gasket 10 and the limiting plate is fixed on the filling cylinder 5.

[0048] In this embodiment, several gaskets 10 are fitted onto the outer wall of the filling cylinder 5 near the discharge port. The number of gaskets 10 is configured according to the different heights of the filling container, flexibly adjusting the height of the discharge port. A limiting plate is provided on the upper surface of the gasket 10 and is fixed to the filling cylinder 5. The limiting plate is used to fix the gasket 10 and prevent the gasket 10 from moving along the filling cylinder 5. The outer diameter of the gasket 10 is adapted to the inner wall of the filling cylinder 5.

[0049] In some specific embodiments of this utility model, the outer side wall of the filling platform 4 is provided with a suitable reinforcing rib 15, which is fixedly connected to the top of the filling seat 3; it is used to strengthen the connection strength between the filling platform 4 and the filling seat 3.

[0050] In some specific embodiments of this utility model, the upper end of the exhaust pipe 7 is connected to a solenoid valve 17, and the other end of the solenoid valve 17 is connected to a vacuum pump 16.

[0051] In this embodiment, the exhaust pipe 7 allows the gas inside the filling tank to be extracted during or before filling, thereby improving the filling quality. The upper end of the exhaust pipe 7 is connected to a solenoid valve 17, and the other end of the solenoid valve 17 is connected to a vacuum pump 16. The solenoid valve 17 is used to control the amount of gas delivered and to stop the flow.

[0052] In some specific embodiments of this utility model, the longitudinal section of the filling platform 4 is an isosceles trapezoid, the width of the upper end of the isosceles trapezoid is 1 / 3 to 1 / 2 of the width of the lower end, and the inner side of the top surface of the filling platform 4 is provided with anti-slip texture, which is a cross-grid pattern.

[0053] In this embodiment, the longitudinal section of the filling platform 4 is an isosceles trapezoid. The width of the upper end of the isosceles trapezoid is 1 / 3 to 1 / 2 of the width of the lower end. The lower end width is typically set to 150mm-300mm, while the corresponding upper end width is 50mm-150mm. The height of the isosceles trapezoid is 80mm-150mm, and the inclination angle of the two sides is 15°-30°. All four corners of the isosceles trapezoid are rounded with a radius of 5mm-8mm to prevent damage from bumps when placing or removing containers. The inner top surface of the filling platform 4 is provided with anti-slip textures. These textures are a cross-grid pattern, with 0.2mm-0.3mm protrusions at the intersections. This effectively prevents containers from sliding or tipping over due to material impact or slight vibration of the filling machine during the filling process, and also further assists in positioning the filling containers.

[0054] In some specific embodiments of this utility model, the filling cylinder 5 is connected to the mounting platform 1 via a flange, and a wear-resistant sealing gasket is provided between the flanges; a detachable sealing ring is provided at the connection between the exhaust pipe 7 and the filling cylinder 5.

[0055] The filling cylinder 5 is connected to the mounting platform 1 via flanges. Wear-resistant sealing gaskets are installed between the flanges. The combination of the flanges and high-strength bolts securely fixes the filling cylinder 5 to the mounting platform 1. The connection strength is high, capable of withstanding the weight of the filling cylinder 5 and its internal material, as well as the impact forces generated during filling, ensuring that the filling cylinder 5 will not shake or shift during operation and guaranteeing filling stability. A removable sealing ring is installed at the connection between the exhaust pipe 7 and the filling cylinder 5. The removable sealing ring has a U-shaped cross-section, allowing it to better fit the outer wall of the exhaust pipe 7 and the inner wall of the mounting hole of the filling cylinder 5 under pressure, achieving a reliable seal and preventing material leakage from the connection to the outside of the filling cylinder 5 or outside air entering the filling cylinder 5 and affecting filling quality. The removable design means that when the sealing ring wears or ages, there is no need to disassemble the entire structure of the filling cylinder 5 and exhaust pipe 7; simply use tools to remove the old sealing ring and replace it with a new one, greatly reducing maintenance difficulty and time costs.

[0056] In some specific embodiments of this utility model, a locking handle 14 is threadedly connected to the outer wall of the mounting platform 1, and the moving end of the locking handle 14 abuts against the lifting mechanism 2.

[0057] Specifically, a locking handle 14 is threaded onto the outer wall of the mounting platform 1. The moving end of the locking handle 14 abuts against the outer wall of the lifting mechanism 2, thereby fixing the relative position between the lifting mechanism 2 and the mounting platform 1. The lifting mechanism 2 is typically connected to an external lifting arm. The lifting arm is existing technology and will not be described in detail here.
