Abstract
Description
Technical Field
[0001] This utility model provides a horizontal filling machine, which relates to the field of industrial filling equipment technology. Background Technology
[0002] Existing horizontal filling machines mainly employ vertical screw feeding or semi-automatic horizontal single screw feeding, combined with weighing sensors to achieve quantitative filling. They meet the powder packaging needs of industries such as food, pharmaceuticals, and chemicals, including products like milk powder, pharmaceutical raw materials, and chemical additives.
[0003] Existing horizontal screw weighing and feeding mechanisms are mostly semi-automatic single screws, which cannot accurately control the filling volume. Commonly used filling machines mostly use vertical screw feeding methods, with the feeding port on the top of the machine. The feeding port is relatively small, making it difficult to feed material. It requires a matching feeding machine, which is troublesome to clean. Disassembly and installation are complicated when changing product types, making it unsuitable for multiple machines to fill multiple products, and there is a problem of easy leakage. Utility Model Content

[0005] This utility model is implemented as follows: it includes a frame, a first dispensing mechanism, a second dispensing mechanism, a first weighing mechanism, a second weighing mechanism, a first conveying mechanism, a second conveying mechanism, a clamping mechanism, and a control system. The first dispensing mechanism and the second dispensing mechanism are installed side by side on the frame. The first dispensing mechanism includes a first hopper, and the second dispensing mechanism includes a second hopper. The volume of the first hopper is larger than the volume of the second hopper. A horizontal spiral conveying mechanism can be detachably installed at the bottom of both the first hopper and the second hopper. The first weighing mechanism and the second weighing mechanism are respectively installed below the first dispensing mechanism and the second dispensing mechanism. The first conveying mechanism and the second conveying mechanism are both horizontally installed on the frame and are respectively located on the sides of the first weighing mechanism and the second weighing mechanism. The clamping mechanism is installed above the first weighing mechanism and the second weighing mechanism and located below the first dispensing mechanism and the second dispensing mechanism.
[0006] The first material dispensing mechanism, the second material dispensing mechanism, the first weighing mechanism, the second weighing mechanism, the first conveying mechanism, the second conveying mechanism, and the clamping mechanism are all connected to the control system.
[0007] As a further preferred embodiment, the horizontal screw conveyor mechanism can be detachably installed with a leak-proof mechanism after extending horizontally along the screw conveying direction.
[0008] As a further preferred embodiment, the anti-leakage mechanism is a cross-shaped connector, which has a horizontal tube and a vertical tube that are intersected. The horizontal tube includes a first horizontal interface and a second horizontal interface, and the vertical tube includes a third vertical interface and a fourth vertical interface. The horizontal screw of the horizontal spiral conveying mechanism extends from the first interface into the horizontal tube but does not extend into the intersection of the horizontal tube and the vertical tube. The fourth interface serves as a filling port.
[0009] As a further preferred embodiment, a leak-proof piston is installed at the third interface. The leak-proof piston extends into the vertical pipe along the third interface and moves up and down along the vertical pipe. When the leak-proof piston moves downward, it enters the intersection range of the horizontal pipe and the vertical pipe. When the leak-proof piston moves upward, it leaves the intersection range of the horizontal pipe and the vertical pipe.
[0010] As a further preferred option, the second interface is equipped with an observation window.
[0011] As a further preferred embodiment, the frame includes a vertical plate, the clamping mechanism is mounted on the vertical plate, the vertical plate is provided with a sliding groove group, the sliding groove group includes an upper groove and a lower groove that are parallel to each other, the clamping mechanism includes an inner clamping plate and an outer clamping plate, the inner clamping plate and the outer clamping plate move along the upper groove and the lower groove respectively.
[0012] As a further preferred embodiment, a baffle that moves up and down is installed between the first conveying mechanism and the first weighing mechanism.
[0013] As a further preferred embodiment, a photoelectric detection device is installed at the end of the first conveying mechanism near the baffle.
[0014] As a further preferred embodiment, both the first conveying mechanism and the second conveying mechanism are equipped with guardrails on both sides along the conveying direction.
[0015] As a further preferred embodiment, the control system includes a screen, a programmable logic controller, and a power supply.
[0016] The working principle of this utility model is as follows: The horizontal filling machine is powered on, and the equipment is initialized and started via the screen buttons. The total filling volume, the filling volume of the first dispensing mechanism, the filling volume of the second dispensing mechanism, and the weight of the empty filling container are set before filling begins. When the first conveying mechanism transports the filling container to the end of the conveyor belt, the photoelectric detection device senses the container, and the lifting cylinder controls the baffle to descend. The clamping mechanism clamps the filling container onto the first weighing mechanism below the first dispensing mechanism, with the upper opening of the filling container facing the filling port. After the weighing sensor of the first weighing mechanism detects the weight of the filling container, the tare process is automatically performed. The weighing sensor monitors the weight change of the weighing platform in real time. After tare is completed, filling begins. The anti-leakage piston moves upward, leaving the intersection of the horizontal and vertical pipes. The servo motor controls the horizontal screw of the horizontal screw conveyor to rotate rapidly. Material falls quickly from the hopper of the first dispensing mechanism through the anti-leakage mechanism into the filling container. When the weighing sensor detects the preset filling volume of the first dispensing mechanism, filling stops. The clamping mechanism clamps the filling container and moves it to the second weighing mechanism below the second dispensing mechanism. The opening of the filling container is directly opposite the slow filling port. The steps are the same as the aforementioned filling steps. The servo motor controls the horizontal screw of the second dispensing mechanism to rotate slowly. After filling the preset filling amount of the second dispensing mechanism, the filling ends. The accuracy is controlled within ±1g. The clamping mechanism clamps the filling container to the second conveying mechanism and is conveyed to the end of the second conveying mechanism by the conveyor belt.
[0017] The beneficial effects of this utility model are as follows: A unique anti-leakage mechanism effectively prevents material spillage after dispensing; a dual-horizontal screw feeding method and a dual-filling head design allow for both fast and slow feeding; two independent filling heads allow for simultaneous filling of two containers, supporting customized containers of different specifications, significantly improving production efficiency; dual weighing sensors ensure filling accuracy and consistency. The horizontal screw conveyor mechanism is connected to the anti-leakage mechanism chuck for easier disassembly and cleaning. The horizontal screw conveyor mechanism and hopper can be disassembled as a whole, enabling modular replacement with fast change speed and convenient switching to other product types for continued dispensing. An intelligent weighing system automatically identifies the tare weight and tare the container the moment it enters the workstation, eliminating the need for manual pre-weighing or calibration. During the filling process, the weighing sensor of the first weighing mechanism detects the material for rapid filling, while the second weighing mechanism automatically triggers a replenishment mechanism for slow filling, achieving closed-loop control throughout the entire process with an error controlled within ±1g, providing a highly efficient and reliable automated filling method. The clamping mechanism can clamp up to three filling containers simultaneously, forming continuous filling. Attached Figure Description

Detailed Implementation
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The horizontal filling machine includes a frame 1, a first dispensing mechanism 2, a second dispensing mechanism 3, a first weighing mechanism 4, a second weighing mechanism 5, a first conveying mechanism 6, a second conveying mechanism 7, a clamping mechanism 10, and a control system (not shown). The frame 1 includes a housing 31. The first dispensing mechanism 2, the second dispensing mechanism 3, the first weighing mechanism 4, the second weighing mechanism 5, the first conveying mechanism 6, the second conveying mechanism 7, and the clamping mechanism 10 are all connected to the control system. The control system is mounted on the frame 1 and includes a screen, a programmable logic controller (PLC), and a power supply.
[0037] See Figure 1The first dispensing mechanism 2 and the second dispensing mechanism 3 are mounted side-by-side on the frame 1 using a known fixed installation method. The first dispensing mechanism 2 includes a first hopper 26 and a horizontal screw conveyor mechanism 12. The first hopper 26 is used to hold the material to be filled, and it has an upper opening as a feeding port and a lower opening as a discharging port. The horizontal screw conveyor mechanism 12 is detachably mounted on the bottom of the first hopper 26 and communicates with the lower opening of the first hopper 26. The second dispensing mechanism 3 includes a second hopper 27 and a horizontal screw conveyor mechanism 12. The second hopper 27 is used to hold the material to be filled, and it has an upper opening as a feeding port and a lower opening for discharging. The horizontal screw conveyor mechanism 12 is detachably mounted on the bottom of the second hopper 27 and communicates with the lower opening of the second hopper 27. In this embodiment, the detachable installation uses a chuck-type connection method for easy disassembly, cleaning, or replacement. In this embodiment, the volume of the first hopper 26 is greater than the volume of the second hopper 27. Alternatively, the volume of the first hopper 26 can be set to be less than or equal to the volume of the second hopper 27, as needed. The horizontal screw conveyor mechanism 12, detachably mounted to the first hopper 26 and the second hopper 27, is used for horizontally conveying the material falling from the first hopper 26 and the second hopper 27. The horizontal screw conveyor mechanism 12 of the first distributing mechanism 2 has the same structure as the horizontal screw conveyor mechanism 12 of the second distributing mechanism 3, and can be adjusted to an appropriate size according to the dimensions of the first hopper 26 and the second hopper 27 to adapt to them. (See also...) Figure 1 , Figure 2 and Figure 3The horizontal spiral conveying mechanism 12 includes a spiral housing, a horizontal screw 13, a coupling 28, and a servo motor 14. One end of the spiral housing is closed, and the other end is open. The middle part of the spiral housing is detachably connected to the first hopper 26 / second hopper 27. The horizontal screw 13 is located inside the spiral housing. The servo motor 14 is connected to the coupling 28 via the screw. The other end of the coupling 28 extends from the closed end of the spiral housing into the spiral housing and connects to the tail end of the horizontal screw 13. The horizontal screw 13 extends horizontally within the spiral housing and is equipped with a spiral rod and spiral blades. The spiral blades are mounted on the spiral rod. Material from the first hopper 26 or the second hopper 27 falls onto the horizontal screw 13. The servo motor 14 drives the horizontal screw 13 to rotate via the coupling 28. As the horizontal screw 13 rotates, the material is continuously conveyed towards the open end along the rotation direction of the spiral blades of the horizontal screw 13. The rotation speed of the horizontal screw 13 is controlled by the servo motor 14 to adjust the filling speed. In practical applications, the material discharge speed (i.e., the filling speed) of the first dispensing mechanism 2 is greater than that of the second dispensing mechanism 3. The first dispensing mechanism 2 is used to fill materials with a larger proportion of the total filling volume, greater than 50% and less than 100% of the total filling volume. The second dispensing mechanism 3 is used to fill materials with a smaller proportion of the total filling volume, filling the remaining material. In this embodiment, each container is filled with 250g, the first dispensing mechanism 2 quickly fills 240g, and the second dispensing mechanism 3 slowly fills 10g.
[0038] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The open end of the horizontal screw conveyor 12 serves as the material outlet. To prevent leakage, a leak-proof mechanism 15 is detachably installed at the open end of the horizontal screw conveyor 12, extending horizontally. In this embodiment, a chuck-type installation method is used for the detachable installation. The detachable connection method facilitates the separation of the horizontal screw conveyor 12 and the leak-proof mechanism 15 for cleaning. The leak-proof mechanism 15 is a cross-shaped connector, which is cross-shaped in overall shape and includes a horizontal tube, a vertical tube, and four interfaces. The horizontal tube and the vertical tube are intersected and connected. The interfaces include a first interface 16, a second interface 17, a third interface 18, and a fourth interface 19. The horizontal tube has two openings, the first interface 16 and the second interface 17, respectively. The central axes of the first interface 16 and the second interface 17 coincide and are located in the same horizontal direction. The vertical tube has two openings, the third interface 18 and the fourth interface 19, respectively, which are vertical. The central axes of the third interface 18 and the fourth interface 19 coincide and are located in the same vertical direction. The third interface 18 is located above the fourth interface 19. The interiors of the cross-shaped connectors are interconnected. The horizontal screw 13 of the horizontal spiral conveying mechanism 12 extends from the first interface 16 into the cross-shaped connector. The opening of the fourth interface 19 narrows and extends downward to form a filling port, from which material falls into the filling container 30. The end of the horizontal screw 12 approaches the intersection of the horizontal tube and the vertical tube, but does not enter the intersection area. The third interface 17 is used to install a leak-proof piston 21, which is adapted to the vertical tube. The upper part of the leak-proof piston 21 is connected to the motor in a known manner. The lower part of the leak-proof piston 21 extends downward along the third interface 17 into the intersection range of the horizontal tube and the vertical tube. During filling, the leak-proof piston 21 moves upward along the vertical tube via the motor, leaving the intersection range of the horizontal tube and the vertical tube. The material can sequentially pass through this intersection range and the filling port into the filling container 30. When the filling target is achieved, the leak-proof piston 21, driven by the motor 32, extends downward to the position between the first interface 16 and the second interface 17, entering the intersection range of the horizontal tube and the vertical tube. In the space where the horizontal tube and the vertical tube intersect, the material falls into the fourth interface 19. In this embodiment, the leak-proof piston 21 is cylindrical, and the second interface 17 is equipped with an observation window 20 for observing the situation inside the cross-shaped connector.
[0039] Both the first conveying mechanism 6 and the second conveying mechanism 7 are mounted on the frame 1, and their installation positions are lower than those of the first distributing mechanism 2 and the second distributing mechanism 3. The first conveying mechanism 6 and the second conveying mechanism 7 are located to the left below the first distributing mechanism 2 and to the right below the second distributing mechanism 3, respectively. Both the first conveying mechanism 6 and the second conveying mechanism 7 are belt conveyors with identical structures, each including a conveyor belt 8, a drive unit, rollers, idlers, a tensioning device, and guardrails 11. The connection method of the conveyor belt 8, the drive unit, the rollers, the idlers, and the tensioning device is existing technology. In this embodiment, the existing belt conveyor is improved by installing guardrails 11 on both sides of the conveyor belt 8 along the conveying direction to prevent the filling containers 50 from falling off. The first weighing mechanism 4 and the second weighing mechanism 5 are installed side by side, below the first dispensing mechanism 2 and the second dispensing mechanism 3, respectively. The first weighing mechanism 4 and the second weighing mechanism 5 are located between the first conveying mechanism 6 and the second conveying mechanism 7, with the first conveying mechanism 6 on one side of the first weighing mechanism 4 and the second conveying mechanism 7 on one side of the second weighing mechanism 5. Both the first weighing mechanism 4 and the second weighing mechanism 5 employ intelligent weighing systems for weighing the filling containers and the filling volume. The first weighing mechanism 4 includes a first weighing platform 22 and a weighing sensor (not shown), used to weigh the weight of the filling container 30 and the weight of the first filling. The first weighing platform 22 is used to place the filling container 30. The second weighing mechanism 5 includes a second weighing platform 23 and a weighing sensor (not shown), used to weigh the weight of the filling container 30 for the second filling. The second weighing platform 23 is used to place the filling container 30 for the second filling. This embodiment does not describe the specific structure of the first weighing mechanism 4 and the second weighing mechanism 5 in detail; however, reference can be made to weighing devices in the prior art.
[0040] See Figure 15The frame includes a vertical plate 29, located at the upper and middle parts of the frame 1. The first conveying mechanism 6, the second conveying mechanism 7, the first dispensing mechanism 2, the second dispensing mechanism 3, the first weighing mechanism 4, and the second weighing mechanism 5 are all mounted on the front side of the vertical plate 29. The clamping mechanism 10 is a parallel gripper type, mounted on the vertical plate 29 and located above the first weighing mechanism 4 and the second weighing mechanism 5. The clamping range of the clamping mechanism 10 extends horizontally from the tail of the first conveying mechanism 6, across the first weighing mechanism 4 and the second weighing mechanism 5, to the head of the second conveying mechanism 7. The vertical plate 29 is provided with a sliding groove group, which corresponds to the clamping mechanism 10. The sliding groove group includes an upper groove 36 and a lower groove 37 arranged in parallel, and the upper groove 36 and the lower groove 37 are arranged in a horizontal direction. (See reference...) Figure 11 , Figure 12 , Figure 13 and Figure 14 The clamping mechanism 10 includes an inner clamping plate 24, an outer clamping plate 25, a telescoping cylinder 33, a lifting cylinder 34, a guide rail 35, and a movable base 38. The inner clamping plate 24 and the outer clamping plate 25 are arranged parallel to each other, forming a gripper for clamping the filling container 30. Both the inner clamping plate 24 and the outer clamping plate 25 are parallel to the vertical plate 29. Anti-slip strips 43 are installed on the inner surfaces of both the inner clamping plate 24 and the outer clamping plate 25. The upper groove 36 corresponds to the inner clamping plate 24, and the lower groove 37 corresponds to the outer clamping plate 25. The back side of the inner clamping plate 24 extends horizontally through the upper groove 36 and is connected to one of the lifting cylinders 34 and one of the telescoping cylinders 33, with the connection method being known. The back of the outer clamping plate 26 is connected to an L-shaped plate 42. The vertical portion of the L-shaped plate 42 is connected to the back of the outer clamping plate 26, and the horizontal portion of the L-shaped plate 42 extends through the lower groove 36 and is connected to another lifting cylinder 34, and also to another scaling cylinder 33. The connection method is known. The two scaling cylinders 33 are used to control the scaling of the inner clamping plate 25 and the outer clamping plate 26, gripping or releasing the filling container 30.
[0041] See Figure 11The movable base 38 includes an upper plate 39, a lower plate 40, and a sliding shaft 41. The back of the inner clamping plate 25 extends horizontally and connects to the upper plate 39. The outer clamping plate 26 is connected to the lower plate 39 via an L-shaped plate. At least two sliding shafts 41 are provided between the upper plate 38 and the lower plate 39. The lifting cylinder 34 controls the upper plate 38 and the lower plate 39 to slide up and down along the sliding shafts 41, thereby driving the inner clamping plate 25 and the outer clamping plate 26 to move vertically back and forth within the height range of the upper groove 36 and the lower groove 37, respectively. This achieves the lifting and lowering of the inner clamping plate 25 and the outer clamping plate 26, so that when clamping the filling container 30, the filling container 30 is raised and removed from the plane, avoiding friction between the bottom of the filling container 30 and the contact part. Two scaling cylinders 33 are mounted on the lower plate 40. The bottom of the movable base 38 is connected to the guide rail 35. The movable base 38 is connected to a cylinder (not shown). Under the action of the cylinder, the cylinder slides left and right along the guide rail 35, thereby driving the inner clamping plate 25 and the outer clamping plate 26 to move horizontally back and forth along the width direction of the upper groove 36 and the lower groove 37, respectively, so as to clamp the filling container 30 for multiple fillings. In this embodiment, the first conveying mechanism 6 is used to convey the filling container 30 to the end of the first conveying mechanism 6. The clamping mechanism 10 moves horizontally along the upper groove 36 and the lower groove 37 to clamp the filling container 30 onto the first weighing mechanism 5, so that the container opening is directly opposite the filling port of the first dispensing mechanism 2. After the first dispensing mechanism 2 completes filling, the clamping mechanism 10 can simultaneously clamp the filling container 30 located on the first weighing mechanism 4 and the filling container 30 located at the end of the first conveying mechanism 6, and move horizontally to the right along the upper groove 36 and the lower groove 37 to clamp and send the filling container 30 located on the first weighing mechanism 4 to the second weighing mechanism 5, so that the container opening is directly opposite the filling port of the second dispensing mechanism 3 for secondary filling. The filling container 30 located at the end of the first conveying mechanism 6 is clamped and sent to the first weighing mechanism 4 for initial filling. The clamping mechanism 10 clamps the filling container 30 that has completed secondary filling and moves it to the conveyor belt 8 of the second conveying mechanism 7. At the same time, it can clamp the filling container 30 on the first weighing mechanism 4 to the second weighing mechanism 5 for secondary filling, and clamp the filling container 30 at the end of the first conveying mechanism 6 to the first weighing mechanism 4 for initial filling.
[0042] To facilitate the clamping mechanism 10 in clamping the filling container 30 located on the first conveying mechanism 6, a photoelectric sensor is further installed at the end of the first conveying mechanism 6, which refers to the end of the first conveying mechanism 6 near the first weighing mechanism 4. A vertically movable baffle 9 is installed between the first conveying mechanism 6 and the weighing mechanism 7. The baffle 9 is connected to a lifting cylinder using existing technology to achieve lifting. The lifting cylinder is mounted on the frame 1. Initially, the baffle 9 blocks the first conveying mechanism 6 and the first weighing mechanism 5. When the photoelectric sensor detects the filling container 30, the first conveying mechanism 6 stops conveying, the baffle 9 descends, the clamping mechanism 10 clamps the filling container 30 located on the first conveying mechanism 7 and moves it to the first weighing mechanism 4. The baffle 9 then rises until the next filling container 30 is conveyed to the end of the first conveying mechanism 7.
[0043] The working principle of this utility model is as follows: The horizontal filling machine is powered on, and the equipment is initialized and started via the screen buttons. The total filling volume, the filling volume of the first dispensing mechanism, the filling volume of the second dispensing mechanism, and the weight of the empty filling container are set before filling begins. When the first conveying mechanism transports the filling container to the end of the conveyor belt, the photoelectric detection device senses the container, and the lifting cylinder controls the baffle to descend. The clamping mechanism clamps the filling container onto the first weighing mechanism below the first dispensing mechanism, with the upper opening of the filling container facing the filling port. After the weighing sensor of the first weighing mechanism detects the weight of the filling container, the tare process is automatically performed. The weighing sensor monitors the weight change of the weighing platform in real time. After tare is completed, filling begins. The anti-leakage piston moves upward, leaving the intersection of the horizontal and vertical pipes. The servo motor controls the horizontal screw of the horizontal screw conveyor to rotate rapidly. Material falls quickly from the hopper of the first dispensing mechanism through the anti-leakage mechanism into the filling container. When the weighing sensor detects the preset filling volume of the first dispensing mechanism, filling stops. The clamping mechanism clamps the filling container and moves it to the second weighing mechanism below the second dispensing mechanism. The opening of the filling container is directly opposite the slow filling port. The steps are the same as the aforementioned filling steps. The servo motor controls the horizontal screw of the second dispensing mechanism to rotate slowly. After filling the preset filling amount of the second dispensing mechanism, the filling ends. The accuracy is controlled within ±1g. The clamping mechanism clamps the filling container to the second conveying mechanism and is conveyed to the end of the second conveying mechanism by the conveyor belt.
[0044] The beneficial effects of this utility model are as follows: A unique anti-leakage mechanism effectively prevents material spillage after dispensing; a dual-horizontal screw feeding method and a dual-filling head design allow for both fast and slow feeding; two independent filling heads allow for simultaneous filling of two containers, supporting customized containers of different specifications, significantly improving production efficiency; dual weighing sensors ensure filling accuracy and consistency. The horizontal screw conveyor mechanism is connected to the anti-leakage mechanism chuck for easier disassembly and cleaning. The horizontal screw conveyor mechanism and hopper can be disassembled as a whole, enabling modular replacement with fast change speed and convenient switching to other product types for continued dispensing. An intelligent weighing system automatically identifies the tare weight and tare the container the moment it enters the workstation, eliminating the need for manual pre-weighing or calibration. During the filling process, the weighing sensor of the first weighing mechanism detects the material for rapid filling, while the second weighing mechanism automatically triggers a replenishment mechanism for slow filling, achieving closed-loop control throughout the entire process with an error controlled within ±1g, providing a highly efficient and reliable automated filling method. The clamping mechanism can clamp up to three filling containers simultaneously, forming continuous filling.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
