Description

Technical Field

[0001] This utility model relates to the field of sauce production technology, specifically a weighing device for packaged sauces. Background Technology

[0002] In the production of instant noodles, the sauce packet is a crucial component, and its accurate weight directly impacts product quality and consumer experience. Currently, although the production of instant noodle sauce packets has achieved a high degree of automation, the lightweight nature of the sauce packets, the non-homogeneous consistency of the sauce, and the chain-like connection after production present technical challenges for online weighing, preventing the successful implementation of automated weighing and monitoring.

[0003] A search revealed a sauce packaging machine with patent publication number CN215205693U, comprising a fixed base, guide columns, a mounting base, a floating base, and a hot press plate. The floating base is driven by a drive unit to move towards the mounting base, causing the two hot press plates to abut against each other. A base is located below the mounting base, with a vertical column on the base. A weighing seat is horizontally hinged to the upper end of the column. A pressure sensor is mounted on the top surface of the weighing seat, and it is driven by a flipping unit to flip along the hinge point with the column. The pressure sensor collects the weight of the sauce packets to determine if the weight is acceptable. Then, the flipping unit drives the weighing seat to flip in different directions, causing the sauce packets to slide into the corresponding collection device, achieving rapid rejection of defective products. In the process of implementing this solution, the following problems were found in the existing technology that have not been well resolved: When the existing technology uses a flipping unit to drive the weighing seat to flip in different directions to collect the sauce after weighing, the flipping unit will be tilted and the sauce packets will fall continuously. The weighing seat cannot catch the new material in time during the flipping process, which will cause the sauce packets to slip to the ground and make it impossible to weigh subsequent sauce packets, causing the weighing process to be blocked. Therefore, it is urgent to design a weighing device for sauce after packaging to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a weighing device for packaged sauces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A weighing device for packaged sauces includes a conveyor frame. One end of the conveyor frame is equipped with an inclined sliding plate, and the sliding plate has a movable groove.

The flip plate is flush with the sliding plate. A weighing component is provided on the flip plate. Flip components are provided at both ends of the first mounting shaft. An anti-fall component is provided on the sliding plate, and the flip components are used to adjust the height of the anti-fall component.

[0007] Furthermore, the weighing assembly includes a weighing groove formed on one side of the top of the flip plate, an installation groove formed at the bottom of the weighing groove, a weighing sensor installed on the inner wall of the installation groove, and a weighing platform inserted into the weighing groove installed on the top of the weighing sensor.

[0008] Furthermore, the top surface of the sliding plate is designed to be smooth, while the top surface of the weighing platform is designed to be rough, and the top surface of the weighing platform is provided with grooves that are evenly distributed.

[0009] Furthermore, the flipping assembly includes a first gear installed at both ends of the first mounting shaft, and support frames are fixed on both outer walls of the lower slide plate. Guide grooves are opened at both ends of the support frames, and slide blocks are slidably arranged on the inner walls of the guide grooves. A first rack is installed on one side of one of the slide blocks, and the first rack meshes with the first gear. Mounting plates are fixed on the bottom of one side of both support frames, and electric push rods are installed at the bottom middle of the mounting plates. The piston end of the electric push rod and the bottom of the two first racks are installed with the same lifting plate.

[0010] Furthermore, a controller is installed on one side of the bottom of the sliding plate, and the controller is electrically connected to the electric push rod and the weighing sensor.

[0011] Furthermore, guide rods are fixed on both sides of the bottom of the mounting plate, and guide holes are provided on the lifting plate for the guide rods to pass through.

[0012] Furthermore, the anti-fall assembly includes a fixed base fixed to the bottom of the sliding plate, and a second mounting shaft is rotatably connected to the fixed base. A second gear is installed at both ends of the second mounting shaft. A second rack is installed on one side of the other sliding base, and the second rack meshes with the second gear. A slot is provided on the sliding plate, and a connecting rod is fixed to the bottom of one side of each of the two second racks. An anti-fall plate passing through the slot is fixed to one end of each of the two connecting rods. A sliding opening for the sauce packet to pass through is provided on the anti-fall plate. Transmission wheels are installed at both ends of the first mounting shaft and both ends of the second mounting shaft, and a transmission belt is drivingly connected to the two transmission wheels on the same side.

[0013] Furthermore, inclined guide plates are installed on both sides of the lower slide plate near the top of the conveyor frame.

[0014] Furthermore, the conveyor frame is a conveying structure with a motor-driven conveyor belt, the top of the lower slide plate is designed in an arc shape, and one end of the lower slide plate is adapted to one end of the conveyor belt of the conveyor frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, by setting up a sliding plate, a weighing component, and a flipping component, when the sauce packet enters the sliding plate along the conveyor frame, it can automatically slide down along the smooth top surface into the weighing groove of the flipping plate. The weight is detected in real time by a weighing sensor. When the weight is too light or too heavy, the controller controls the electric push rod to drive the flipping component to flip, so that the unqualified products fall into the collection boxes at both ends along with the flipping plate, while the qualified products fall into the collection box at the bottom end, realizing automatic weighing and sorting of sauce packets and improving production efficiency.

[0018] In this invention, the top surface of the weighing platform is designed to be rough and has grooves. Combined with the guide plate, this increases the friction between the sauce packet and the weighing platform, preventing continuous slippage that could lead to weighing errors. The guide plate also guides the sauce packet to slide down in the center, and the smooth surface of the slide plate allows for rapid sliding, ensuring that the sauce packet stops stably at the designated position on the weighing platform and that the sauce packet is accurately positioned.

[0019] In this invention, the flipping component and the anti-fall component are linked by a transmission belt. When the flipping plate tilts to remove defective products, the anti-fall plate simultaneously adjusts the height of the sliding opening to prevent the next undetected sauce packet from continuing to slide down, thus preventing the next sauce packet from falling due to the flipping action.

[0027] 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.

[0028] Please see Figures 1-6In this embodiment of the present invention, a weighing device for packaged sauce includes a conveyor frame 1. One end of the conveyor frame 1 is fitted with an inclined sliding plate 2, and the sliding plate 2 has a movable groove 19. A first mounting shaft 18 is rotatably mounted in the middle of the movable groove 19. A flip plate 6, inserted into the movable groove 19, is mounted on the first mounting shaft 18. The flip plate 6 is flush with the sliding plate 2. A weighing assembly is mounted on the flip plate 6, including a weighing groove 21 on one side of the top of the flip plate 6. A mounting groove 22 is formed at the bottom of the weighing groove 21. A weighing sensor 9 is mounted on the inner wall of the mounting groove 22. A weighing platform 15, inserted into the weighing groove 21, is mounted on the top of the weighing sensor 9. Flip plates are provided at both ends of the first mounting shaft 18. The rotating assembly includes first gears 14 mounted at both ends of the first mounting shaft 18, and support frames 8 are fixed to the outer walls of both sides of the lower slide plate 2. Guide grooves 17 are provided at both ends of the support frames 8, and slide blocks are slidably mounted on the inner walls of the guide grooves 17. A first rack 13 is mounted on one side of one of the slide blocks, and the first rack 13 meshes with the first gear 14. Mounting plates 20 are fixed to the bottom of one side of both support frames 8, and an electric push rod 10 is mounted at the center of the bottom of the mounting plate 20. The piston end of the electric push rod 10 and the bottom of the two first racks 13 are mounted on the same lifting plate 11. A controller 3 is mounted on one side of the bottom of the lower slide plate 2, and the controller 3 is electrically connected to the electric push rod 10 and the weighing sensor 9. Weighing sensor 9 detects weight in real time. When the weight is too light or too heavy, controller 3 controls electric push rod 10 to drive the flipping component to flip, causing unqualified products to fall with flipping plate 6, while qualified products continue to fall with slide plate 2. This achieves automatic weighing and sorting of sauce packets, improving production efficiency. Anti-fall component 5 is installed on slide plate 2, and the flipping component is used to adjust the height of anti-fall component 5. Anti-fall component 5 includes a fixed base 501 fixed to the bottom of slide plate 2, and a second mounting shaft 508 is rotatably connected to the fixed base 501. Second gears 502 are installed at both ends of the second mounting shaft 508, and a second rack 503 is installed on one side of another slide, with the second rack 503 meshing with the second gear 502. The slide plate 2 has a slot 507, and a connecting rod 509 is fixed to the bottom of one side of each of the two second racks 503. One end of each connecting rod 509 is fixed with a fall arrestor 504 that passes through the slot 507. The fall arrestor 504 has a sliding opening 506 for the sauce packet to pass through. Both ends of the first mounting shaft 18 and both ends of the second mounting shaft 508 are equipped with drive wheels, and the two drive wheels on the same side are connected to a drive belt 505. The flipping component and the fall arrestor 5 are linked by the drive belt 505. When the flipping plate 6 tilts to remove defective products, the fall arrestor 504 adjusts the height of the sliding opening 506 simultaneously to prevent the next undetected sauce packet from continuing to slide down, thus preventing the next sauce packet from falling due to the flipping action.

[0029] Specifically, the top surface of the sliding plate 2 is designed to be smooth, while the top surface of the weighing platform 15 is designed to be rough. The top surface of the weighing platform 15 is provided with equally spaced grooves 16 to increase the friction with the sauce packet, prevent weighing deviation caused by slippage, and ensure accurate and reliable test data.

[0030] Specifically, guide rods 12 are fixed on both sides of the bottom of the mounting plate 20, and guide holes for the guide rods 12 to pass through are provided on the lifting plate 11 to reduce shaking and ensure that the flipping action is smooth and reliable.

[0031] Specifically, inclined guide plates 4 are installed on both sides of the top of the slide plate 2 near the conveyor frame 1 to guide the sauce bag to slide down in the middle. Combined with the fast sliding characteristics of the smooth surface of the slide plate 2, the sauce bag is stably stopped at the designated position of the weighing platform 15, improving the positioning accuracy.

[0032] Specifically, the conveyor frame 1 is a conveying structure with a motor-driven conveyor belt, and the conveyor frame 1 is used for intermittent conveying of sauce packets. The top of the lower slide plate 2 is designed to be arc-shaped, and one end of the lower slide plate 2 is adapted to one end of the conveyor belt of the conveyor frame 1, so that the sauce packets enter the weighing area one by one in an orderly manner, avoiding stacking and affecting the detection efficiency.

[0033] Specifically, the bottom of the slide plate 2 is provided with three collection boxes 7, two of which are located below the two ends of the flip plate 6, and the other collection box 7 is located below the bottom of the slide plate 2, which facilitates the collection of qualified and unqualified products.

[0034] The working principle of this utility model is as follows: the sauce packets are conveyed one by one to the end through the conveyor frame 1 in an intermittent conveying manner. The spacing is controlled by the start and stop of the conveyor belt to avoid stacking. When the sauce packets reach the end of the conveyor frame 1, they fall smoothly into the lower slide plate 2 due to the arc surface design and tilt angle of the top of the lower slide plate 2. They slide down the smooth top surface at an accelerated speed. The guide plates 4 on both sides of the top of the lower slide plate 2 are tilted to guide the sauce packets to move towards the center, ensuring that they slide along the central axis of the lower slide plate 2 and avoiding deviation that would cause a weighing position deviation.

[0035] When the sauce packet slides to the flipping plate 6, the friction generated by the rough surface and groove 16 on the top of the weighing platform 15 slows down and stops stably in the weighing groove 21, completing the positioning. At this time, the weight of the sauce packet is detected in real time by the weighing sensor 9 and the data is transmitted to the controller 3. The controller 3 has a preset qualified weight range and immediately compares the detected data with the preset value to determine whether the sauce packet is qualified. If the weight is lower or higher than the qualified range, the controller 3 triggers a signal to the electric push rod 10. The piston end of the electric push rod 10 pushes the lifting plate 11 to move up or down, driving the first racks 13 on both sides to rise and fall synchronously. The first racks 13 and the first gear 14 mesh to drive the first mounting shaft 18 to rotate, thereby driving the flipping plate 6 to rotate around the first mounting shaft 18. The unqualified sauce packet slides down to the corresponding collection box 7 due to gravity. When the sauce packet reaches the qualified weight range, the flipping component does not work. At this time, it continues to slide down and falls into the corresponding collection box 7.

[0036] When the flip plate 6 rotates, the transmission belt 505 and the transmission wheel drive the second mounting shaft 508 to rotate synchronously. The second gears 502 at both ends of the second mounting shaft 508 also rotate, driving the second rack 503 to slide along the guide groove 17 of the support frame 8. The second rack 503 drives the anti-fall plate 504 to move up and down through the connecting rod 509, and the height of its sliding opening 506 is reduced, preventing subsequent undetected sauce packets from continuing to slide down to the flipping area and avoiding falling during the removal process.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
