Description

Technical Field

[0001] This utility model relates to the field of automatic filling equipment technology, and in particular to a fully automatic ton tank filling machine. Background Technology

[0002] Currently, packaging line production is becoming increasingly automated. Fully automated packaging lines can save significant labor costs, thereby achieving cost reduction and efficiency improvement. A ton tank filling machine is an industrial device used for filling large-capacity containers (usually referring to "ton drums" or "ton boxes," with a volume typically around 1000 liters, capable of holding approximately 1 ton of liquid material). Existing ton tank filling machines mostly rely on manual operation, using manual valve control for filling. Filling is done above the ton tank, and due to its large size, workers need to climb to work, significantly increasing safety risks. When filling materials that are often irritating, personnel must wear heavy protective clothing, greatly reducing automation, increasing manpower and material costs, decreasing production efficiency, and posing certain safety hazards. Therefore, there is an urgent need to optimize the structure of existing ton tank filling machines. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic ton-tank filling machine that achieves automatic filling, improves filling efficiency, and ensures the safety of filling production.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A fully automatic ton-tank filling machine includes a housing, the housing including a frame and an automatic sensor door located on the side of the frame, the frame and the automatic sensor door forming a sealed chamber.

[0006] The filling station includes a weighbridge located in a sealed chamber and a drum rack placed on the weighbridge. The drum rack is used to hold the ton tank, and the weighbridge is connected to an automatic sensor door.

[0007] The transport device is equipped with a lifting platform adapted to the barrel rack for transferring the barrel rack;

[0008] The filling unit includes a feeding section and a discharging section connected together. The inlet extends to the outside of the box and connects to the hopper. The outlet faces the filling position and works with a weighing scale to perform automatic weighing and filling.

[0009] Furthermore, the feeding section includes a feeding bin and a feeding rod that is vertically inserted into the feeding bin. A flexible partition is fixedly connected to the middle of the feeding rod. The outer ring of the flexible partition is sealed and fixedly connected to the inner wall of the feeding bin, thereby dividing the feeding bin into an upper chamber and a lower chamber. The inlet and outlet of the filling section are both located in the lower chamber. The outlet opens and closes as the feeding rod extends and retracts.

[0010] Furthermore, the feeding rod includes a plug, a lower pull rod, and an upper pull rod arranged sequentially from bottom to top; the feeding bin includes an upper bin body and a lower bin body; the flexible partition is a diaphragm; the inner ring of the diaphragm is sealed between the upper pull rod and the lower pull rod, and the outer ring is sealed between the upper bin body and the lower bin body.

[0011] Furthermore, the inner ring of the diaphragm is provided with a first annular protrusion, and the bottom of the upper pull rod and the upper part of the lower pull rod are respectively provided with an upper pressure plate and a lower pressure plate, and an annular groove is formed between the upper pressure plate and the lower pressure plate, and the first annular protrusion is sealed in the annular groove.

[0012] Furthermore, the diaphragm is provided with a second annular protrusion near the inner wall of the feeding hopper, and the bottom of the upper hopper and the top of the lower hopper are respectively provided with annular arc grooves corresponding to the second annular protrusion, with both sides of the annular arc grooves being rounded.

[0013] Furthermore, a first mounting plate is fixedly suspended on the top of the frame section, and a feeding cylinder is fixedly mounted on the first mounting plate. The piston rod of the feeding cylinder is set vertically downward and fixedly connected to the feeding rod.

[0014] Furthermore, the weighbridge is provided with limiting parts at both ends on the side away from the automatic sensor door. The limiting parts include two vertically distributed baffles, each of which is fixedly mounted on the side of the weighbridge.

[0015] Furthermore, the feeding section includes a feeding pipe, a manual valve, an automatic valve, and a discharging pipe arranged sequentially along the material conveying direction, and the unloading section is connected to the discharging pipe.

[0016] Furthermore, a second mounting plate is fixedly mounted on the side of the frame portion, and a receiving cylinder is fixedly mounted on the second mounting plate. The piston rod of the receiving cylinder is horizontally arranged and fixedly connected to a receiving box located below the outlet of the filling portion.

[0017] Furthermore, the outlet cover of the receiving box and the filling section is equipped with a protective cover, and the protective cover is provided with an exhaust pipe extending to the outside of the box body, and the exhaust pipe is connected to a negative pressure device.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:

[0019] (1) The automatic sensor door of this utility model automatically opens when it senses the transport device. The transport device delivers the barrel rack containing the ton trough to the weighing scale, and works with the filling unit to carry out automatic filling. When the weighing scale detects that the weight meets the filling requirements, the filling unit stops filling and the automatic sensor door opens. The transport device then transfers the barrel rack to the outside of the box to complete the automatic filling process. At the same time, the filling process is set in a sealed space to avoid the spread of the irritating odor of the material during filling, thereby improving filling efficiency and ensuring the safety of filling production.

[0020] (2) By replacing the traditional sealing partition with a flexible partition in the feeding bin, this utility model can effectively prevent materials from entering the upper chamber when the feeding rod and the sealing partition move relative to each other, thus avoiding contamination of the upper part of the feeding rod.

[0021] (3) The present invention sets both the feeding rod and the feeding bin as a split structure. The upper and lower pull rods and the upper and lower bins form a limit on the diaphragm, thereby forming a seal. The structure is simple and easy to assemble.

[0022] (4) This utility model adds a pressure plate to the pull rod and sets a first annular protrusion on the diaphragm to facilitate the sealing connection between the pull rod and the inner ring of the diaphragm.

[0023] (5) This utility model adds a second annular protrusion to the diaphragm and provides corresponding annular arc grooves on the upper and lower chambers. The annular arc grooves provide buffer for the upper and lower deformation of the diaphragm, reduce wear on the diaphragm, and extend its service life.

[0024] (6) This utility model uses a feeding cylinder to drive the feeding rod to rise and fall, which has a simple structure and a rapid action response.

[0025] (7) This utility model provides a limiting part to the weighing scale to limit the transport device, so that the ton tank can stay directly below the filling part.

[0026] (8) The present invention is equipped with an automatic valve and a manual valve in the feeding section to realize two feeding modes: automatic and manual. During normal use, the manual valve is always open, and the automatic valve realizes the automatic opening and closing of the feeding section. When there is a power failure, malfunction or long-term shutdown, the feeding section can be quickly closed through the manual valve.

[0027] (9) This utility model uses a receiving cylinder to drive the receiving box to extend horizontally, so that it can extend to the bottom of the filling section after filling is completed, preventing residual material from falling and contaminating the weighing scale below.

[0028] (10) By adding an exhaust pipe of an external negative pressure device, this utility model can remove the odor in time when filling materials with irritating odors, thus avoiding the heavy odor in the workshop after the automatic sensor door is opened, and further protecting the physical and mental health of workers.

Detailed Implementation

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] (Example 1)

[0038] like Figures 1 to 4 The fully automatic ton-tank filling machine shown includes a housing, a filling position, a transport device, and a filling section. The housing includes a frame section 1 and an automatic sensor door 2 located on the side of the frame section 1. The frame section 1 and the automatic sensor door 2 form a sealed chamber. The filling position and the filling section are both located in the sealed chamber. The transport device transfers the ton-tank to be filled from outside the housing to the filling position. The filling section is located above the filling position and is used for filling materials. After filling is completed, the automatic sensor door opens, and the transport device transfers the ton-tank to outside the housing, completing the automatic filling process.

[0039] Specifically, the automatic sensor door 2 is an explosion-proof automatic sensor roller shutter door, suitable for various complex workshop environments. It has built-in photoelectric sensors to achieve automatic opening and closing. The transportation device uses a forklift, which lifts and transfers the load via its forks. The filling station includes a weighbridge 3 located in a sealed chamber and a drum rack 4 placed on the weighbridge 3. The bottom of the drum rack 4 is adapted to the forklift forks for easy insertion. The upper part of the drum rack 4 is adapted to the ton tank for placing the ton tank. The weighbridge 3 is signal-connected to both the automatic sensor door 2 and the filling station. It works in conjunction with the filling station to perform automatic weighing and filling, and sends a signal to the automatic sensor door 2 after filling to open the automatic sensor door 2. Limiting parts 3-1 are provided at both ends of the weighbridge 3 on the side away from the automatic sensor door. The limiting parts 3-1 include two vertically distributed baffles, each fixed to the side of the weighbridge 3, which provide a limit for the forklift, allowing the ton tank to stop directly below the filling station.

[0040] The filling section includes a feeding section 5 and a discharging section 6 connected together. The feeding section 5 includes a feeding pipe 5-1, a manual valve 5-2, an automatic valve 5-3, and a discharging pipe 5-4 arranged sequentially along the material conveying direction. The inlet of the feeding pipe 5-1 extends to the outside of the box and connects to the hopper. By setting two types of valves, both automatic and manual feeding modes are realized. Under normal use, the manual valve is always open, and the automatic valve realizes the automatic opening and closing of the feeding section. In the event of a power outage, malfunction, or long-term shutdown, the feeding section can be quickly closed through the manual valve.

[0041] The unloading section 6 includes an unloading bin, an unloading rod, and a flexible partition 6-1. The unloading bin includes an upper bin body 6-2 and a lower bin body 6-3. The unloading rod is inserted into the unloading bin and includes a plug 6-4, a lower pull rod 6-5, and an upper pull rod 6-6 arranged sequentially from bottom to top. A first mounting plate 7 is fixedly suspended on the top of the frame section 1. An unloading cylinder 8 is fixedly mounted on the first mounting plate 7. The piston rod of the unloading cylinder 8 is vertically downward and fixedly connected to the upper pull rod 6-6, realizing the lifting and lowering movement of the unloading rod.

[0042] The bottom of the upper pull rod 6-6 and the upper part of the lower pull rod 6-5 are respectively provided with an upper pressure plate 6-7 and a lower pressure plate 6-8. The flexible partition 6-1 is a diaphragm. The inner ring of the diaphragm is provided with a first annular protrusion 6-1-1. An annular groove is formed between the upper pressure plate 6-7 and the lower pressure plate 6-8. When the upper and lower pull rods are assembled, the first annular protrusion 6-1-1 is pressed by the upper pressure plate 6-7 and the lower pressure plate 6-8, naturally sealing itself in the annular groove to form a fixed connection. The outer ring of the diaphragm extends between the upper chamber 6-2 and the lower chamber 6-3. It is pressed by the upper chamber 6-2 and the lower chamber 6-3 during assembly to form a sealed fixed connection. The diaphragm divides the discharge bin into an upper chamber and a lower chamber. The discharge pipe 5-4 connects to the lower chamber. The bottom of the lower chamber is provided with an opening that matches the plug 6-4, forming a filling outlet for the filling position. When the feeding rod moves up and down, it drives the plug to open and close the outlet of the filling section. At the same time, the diaphragm undergoes flexible deformation. The relative positions of the inner and outer rings with the inner wall of the feeding hopper and the feeding rod remain unchanged. Compared with traditional sealing partitions, this can effectively prevent materials from entering the upper chamber when the feeding rod and the sealing partition move relative to each other, thus avoiding contamination of the upper part of the feeding rod.

[0043] A second annular protrusion 6-1-2 is provided on the inner wall of the diaphragm near the feeding hopper. The bottom of the upper hopper 6-2 and the top of the lower hopper 6-3 are respectively provided with annular grooves corresponding to the second annular protrusion 6-1-2, with rounded transitions on both sides of the annular grooves. These annular grooves provide cushioning for the vertical deformation of the diaphragm, reducing wear and extending its service life.

[0044] A second mounting plate 9 is fixedly mounted on the side of the frame section 1. A receiving cylinder 10 is fixedly mounted on the second mounting plate 9. The piston rod of the receiving cylinder 10 is horizontally set and fixedly connected to a receiving box 11 located below the outlet of the filling section. The receiving box 11 and the outlet of the filling section are covered with a protective cover 12. The protective cover 12 is provided with an exhaust pipe 13 extending to the outside of the box body. The exhaust pipe 13 is connected to a negative pressure device. The receiving box 11 is driven to extend and retract horizontally by the receiving cylinder 10, so that it can extend to below the outlet of the filling section in time after filling, preventing residual material from falling and contaminating the weighbridge below. When filling materials with irritating odors, the exhaust pipe 13 can promptly remove the odor, avoiding a strong odor throughout the workshop after the automatic sensor door is opened, further protecting the physical and mental health of the workers.

[0045] The working principle of this embodiment is as follows: When the forklift carrying the ton tank enters the designated position in the filling area, the photoelectric sensor sends a signal to the automatic sensor door 2, the roller shutter door motor starts, the roller shutter door opens, and the ton tank enters the frame part 1 and is placed in the filling position. When the filling material is mostly irritating (such as polyurethane), people cannot be in this environment for a long time. After the ton tank is in place, the forklift leaves, the roller shutter door closes, and a sealed space is formed. In the feeding part 5, the material enters the unloading part 6, and the unloading cylinder moves the plug upward, and the material is filled. During the filling process, the exhaust pipe sucks in air to remove the irritating and toxic gases generated during the filling process, making the filling area cleaner.

[0046] The automatic valve uses a three-position flanged pneumatic ball valve. When the filling reaches 90% of the target weight, the three-position pneumatic ball valve automatically closes the valve's internal ball angle, reducing the filling speed and making the final target weight more accurate. Once the target weight is reached, the plug moves down, sealing the filling outlet, at which point filling is complete. After filling, the receiving box 11 extends to ensure that residual material does not drip onto the ground or onto the container, preventing contamination of the ton tank. Simultaneously, the roller shutter door opens, allowing a forklift to enter and remove the ton tank. Once the ton tank leaves the photoelectric sensing area, the roller shutter door automatically closes; this completes one cycle.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
