Description

Technical Field

[0001] This utility model relates to the field of weighing device technology, specifically to an online weighing device for finished baby food nutritional packs. Background Technology

[0002] In modern industrial production lines, weighing devices are always an indispensable and crucial component. These devices integrate high-precision sensors, advanced signal processing modules, and other precision components, enabling them to capture subtle changes in material weight. Through real-time feedback of accurate data, weighing devices provide solid data support for the continuous and stable operation of the production process, allowing the production line to efficiently and accurately sort materials, thereby improving overall production efficiency and product quality.

[0003] In existing technologies, during prolonged weighing operations, finished products inevitably come into contact with and rub against the weighing surface. Due to the presence of small amounts of impurities, dust, or fine debris from the packaging material itself on the packaging bag surface, these impurities gradually adhere to the weighing surface. These residual impurities alter the flatness and uniformity of the sensor's force-bearing surface, interfering with the sensor's accurate perception of the actual weight of the packaged product, leading to measurement deviations. In production processes with stringent requirements, this deviation may result in substandard product weight. To eliminate the impact of these impurities on weighing accuracy, manual cleaning of the weighing surface becomes essential. However, this undoubtedly adds an extra burden to the workers; the cleaning process is not only time-consuming but also severely impacts overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an online weighing device for finished complementary food nutritional packs, so as to solve the problems mentioned in the background art, which are that when weighing, the finished product impurities and debris adhere to the weighing surface, causing measurement deviations and affecting the product sorting accuracy. At the same time, manual cleaning, although necessary, increases the burden, consumes time, and reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online weighing device for finished complementary food nutritional packs, including a mounting base plate, a first mounting bracket fixedly mounted on the mounting base plate, a first fixed bracket fixedly mounted on the first mounting bracket, a first motor fixedly mounted on the first fixed bracket, a first threaded rod fixedly connected to the output end of the first motor, a sliding bracket threadedly connected to the first threaded rod, a second motor fixedly mounted on the sliding bracket, a second threaded rod fixedly connected to the output end of the second motor, a sliding seat slidably connected to the sliding bracket, a first cleaning roller rotatably connected to the sliding seat, and a component fixedly mounted on the sliding bracket.

[0006] In the preferred embodiment of this technical solution, a limiting groove is formed at the relative position of the sliding seat to the first cleaning roller, and the first cleaning roller is rotatably connected to the groove.

[0007] According to the preferred embodiment of this technical solution, the weighing component includes a support base fixedly installed on a first mounting bracket, a support plate slidably connected to the support base, and a weighing sensor body installed on the support plate.

[0008] According to the preferred embodiment of this technical solution, the sorting component includes a controller body mounted on a first mounting bracket, a third motor fixedly mounted on the first mounting bracket, a first conveyor roller fixedly connected to the output end of the third motor, and a first conveyor belt driven to the first conveyor roller. The third motor is used to drive the first conveyor roller to rotate.

[0009] According to the preferred embodiment of this technical solution, the damping component includes a first mounting base fixedly mounted on a support plate, a second mounting base fixedly mounted on the support plate, a first connecting bracket disposed between the first mounting base and the second mounting base, a second sliding block slidably connected to the first connecting bracket, a first rotating rod rotatably connected between the second sliding block and the first mounting base, a second rotating rod rotatably connected between the second mounting base and the second sliding block, a damper body disposed between the first mounting base and the second mounting base, and a first spring fixedly connected between the second mounting base and the first mounting base.

[0010] According to the preferred embodiment of this technical solution, the material distribution component includes a second mounting bracket fixedly mounted on the mounting base plate, a fourth motor fixedly mounted on the second mounting bracket, a rotating disc fixedly connected to the output end of the fourth motor, and a first guide plate fixedly mounted on the second mounting bracket.

[0011] In a preferred embodiment of this technical solution, the conveying assembly includes a third mounting bracket fixedly mounted on a mounting base plate, a fifth motor fixedly mounted on the third mounting bracket, a second conveying roller fixedly connected to the output end of the fifth motor, a second conveyor belt driven by the second conveying roller, a support roller rotatably connected to the third mounting bracket, and a second guide plate fixedly mounted on the third mounting bracket.

At the same time, during the movement of the sliding seat, the fixed rack meshes with the first gear on the first cleaning roller, so that the first cleaning roller rotates synchronously in the rotating groove. This eliminates the need to set a drive source for the first cleaning roller, reducing energy consumption, and prevents residual materials from adhering to the weighing-related areas. This prevents the subsequent weighing data from being deviated due to residual materials, and provides a clean environment for the accurate detection of the weighing components.

[0014] 2. By setting up a shock-absorbing component, external vibration can be converted into sliding displacement of the second sliding block on the first connecting bracket. Combined with the elastic deformation of the first spring to absorb part of the energy, and then the remaining vibration energy is attenuated by the damper body, the vibration amplitude transmitted to the support plate and the weighing sensor body is greatly reduced, avoiding the interference of vibration on the weighing sensor body, ensuring that it can stably capture the true weight signal of the material, and significantly improving the accuracy and consistency of the weighing data.

[0017] 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.

[0018] Please see Figure 1 - Figure 8This utility model provides an embodiment of an online weighing device for finished complementary food nutritional packs, including a mounting base plate 1, a first mounting bracket 21 fixedly mounted on the mounting base plate 1, a first fixed bracket 22 fixedly mounted on the first mounting bracket 21, a first motor 23 fixedly mounted on the first fixed bracket 22, a first threaded rod 24 fixedly connected to the output end of the first motor 23, a sliding bracket 25 threadedly connected to the first threaded rod 24, a second motor 26 fixedly mounted on the sliding bracket 25, a second threaded rod 27 fixedly connected to the output end of the second motor 26, and a sliding bracket... A sliding seat 28 connected to the sliding bracket 25, a first cleaning roller 29 rotatably connected to the sliding seat 28, a fixed rack 210 fixedly mounted on the sliding bracket 25, a first gear 211 fixedly connected to the first cleaning roller 29, a material distribution assembly mounted on the mounting base plate 1, a conveying assembly mounted on the mounting base plate 1, a limiting assembly mounted on the conveying assembly, a weighing assembly mounted on the first mounting bracket 21, a shock-absorbing assembly mounted on the weighing assembly, and a sorting assembly mounted on the shock-absorbing assembly; the sliding bracket 25 is slidably connected to the first fixed bracket 22, and the sliding seat 28 is threadedly connected to the first fixed bracket 22. On the threaded rod 27, the first gear 211 meshes with the fixed rack 210. The first motor 23 drives the first threaded rod 24 to rotate, and the second motor 26 drives the second threaded rod 27 to rotate. When the sliding seat 28 moves, it engages with the first gear 211 through the fixed rack 210, driving the first cleaning roller 29 to rotate. When the device is working, the material is first initially dispersed by the material distribution component and the finished product is conveyed to the conveying component. The conveying component then conveys the finished product to the first mounting bracket 21. During conveying, the limiting component restricts the flow. After the finished product is conveyed to the first mounting bracket 21, it is then conveyed by the weight-bearing assembly. The finished products are weighed and sorted by the sorting component. After weighing, the sorting component needs to be cleaned. The first motor 23 drives the first threaded rod 24 to rotate, which drives the sliding bracket 25 to slide along the first fixed bracket 22. At the same time, the second motor 26 drives the second threaded rod 27 to rotate, which drives the sliding seat 28 to move on the sliding bracket 25. During the movement of the sliding seat 28, the fixed rack 210 meshes with the first gear 211 on the first cleaning roller 29, so that the first cleaning roller 29 rotates in the trough to clean the sorting work and prevent it from affecting the weighing component.

[0019] Please see Figure 1 - Figure 3 A further solution based on this embodiment is as follows: the sliding seat 28 has a limiting groove at the relative position of the first cleaning roller 29, and the first cleaning roller 29 is rotatably connected to the groove. This structure limits the first cleaning roller 29 through the groove, ensuring that the position of the first cleaning roller 29 is accurate during rotation and avoiding deviation, thereby improving the stability and reliability of the cleaning operation.

[0020] Please see Figure 1 - Figure 4 A further solution based on this embodiment is as follows: the weighing component includes a support base 215 fixedly installed on the first mounting bracket 21, a support plate 216 slidably connected to the support base 215, and a weighing sensor body 217 installed on the support plate 216. The specific model of the weighing sensor body 217 is OMEGA LCKD. The support base 215 provides a stable foundation for the overall structure. The sliding connection design between the support plate 216 and the support base 215 can reduce the direct impact of external vibration on the weighing sensor, enabling the weighing sensor body 217 to more stably and accurately detect the weight of the material, thereby improving the accuracy of the weighing data.

[0021] Please see Figure 1 - Figure 4 A further solution based on this embodiment is as follows: the sorting component includes a controller body 226 mounted on a first mounting bracket 21, a third motor 212 fixedly mounted on the first mounting bracket 21, a first conveyor roller 213 fixedly connected to the output end of the third motor 212, and a first conveyor belt 214 driven by the first conveyor roller 213. The third motor 212 is used to drive the first conveyor roller 213 to rotate. The controller body 226 is specifically model DP25B-S. The controller body 226 can accurately control the forward and reverse rotation of the third motor 212 according to preset instructions or detection signals, and drive the first conveyor belt 214 to operate through the first conveyor roller 213 to realize the automated sorting and conveying of materials.

[0022] Please see Figure 1 - Figure 5 A further embodiment of this solution is as follows: the shock absorption assembly includes a first mounting base 218 fixedly mounted on a support plate 216, a second mounting base 219 fixedly mounted on a support base 215, a first connecting bracket 220 disposed between the first mounting base 218 and the second mounting base 219, a second sliding block 221 slidably connected to the first connecting bracket 220, a first rotating rod 222 rotatably connected between the second sliding block 221 and the first mounting base 218, and a second rotating rod 222 rotatably connected between the second mounting base 219 and the second sliding block 221. The rod 223, the damper body 224 disposed between the first mounting base 218 and the second mounting base 219, and the first spring 225 fixedly connected between the second mounting base 219 and the first mounting base 218, when subjected to external impact force, the first rotating rod 222 and the second rotating rod 223 drive the second sliding block 221 to slide on the first connecting bracket 220, and the elastic deformation of the first spring 225 absorbs part of the impact force, while the damper body 224 further attenuates the vibration energy, effectively reducing the impact of vibration on the support plate 216 and the weighing component above.

[0023] Please see Figure 1- Figure 6 A further solution based on this embodiment is as follows: the material distribution component includes a second mounting bracket 31 fixedly mounted on the mounting base plate 1, a fourth motor 32 fixedly mounted on the second mounting bracket 31, a rotating disk 33 fixedly connected to the output end of the fourth motor 32, and a first guide plate 34 fixedly mounted on the second mounting bracket 31. The fourth motor 32 drives the rotating disk 33 to rotate. When the disk rotates, the accumulated material is pushed to the edge by centrifugal force, which disperses the material and avoids the problem of subsequent blockage and uneven conveying caused by its concentration.

[0024] Please see Figure 1 - Figure 7 A further embodiment of this solution is as follows: the conveying assembly includes a third mounting bracket 35 fixedly mounted on the mounting base plate 1, a fifth motor 36 fixedly mounted on the third mounting bracket 35, a second conveying roller 37 fixedly connected to the output end of the fifth motor 36, a second conveying belt 38 drivenly connected to the second conveying roller 37, a support roller 39 rotatably connected to the third mounting bracket 35, and a second guide plate 310 fixedly mounted on the third mounting bracket 35. The second conveying roller 37 is rotatably connected to the third mounting bracket 35. The fifth motor 36 is used to drive the second conveying roller 37 to rotate. The support roller 39 is used to support the second conveying belt 38. The third mounting bracket 35 provides stable support for the conveying structure. The fifth motor 36 drives the second conveying roller 37 to drive the second conveying belt 38 to rotate and realize material conveying. The support roller 39 can effectively prevent the second conveying belt 38 from sagging due to the weight of the material and ensure that the conveying plane is flat.

[0025] Please see Figure 1 - Figure 8 A further solution based on this embodiment is as follows: The limiting component includes a third fixed seat 311 fixedly installed on the third mounting bracket 35, a third threaded rod 312 rotatably connected to the third fixed seat 311, an adjusting knob 313 fixedly connected to one end of the third threaded rod 312, a sliding support rod 314 threadedly connected to the third threaded rod 312, and a limiting baffle 315 fixedly installed on the sliding support rod 314. The adjusting knob 313 is used to adjust the rotation of the third threaded rod 312. By rotating the adjusting knob 313, the third threaded rod 312 is driven to rotate, which causes the threaded sliding support rod 314 to drive the limiting baffle 315 to move. The distance between the limiting baffles 315 can be flexibly adjusted according to the material size to achieve limiting of materials of different specifications and prevent deviation during material conveying.

[0026] Working principle: First, the fourth motor 32 drives the rotating disk 33 to rotate, using centrifugal force to push the accumulated material to the edge. The dispersed material is guided by the first guide plate 34 and enters the conveying assembly in an orderly manner. The fifth motor 36 drives the second conveying roller 37 to rotate, which in turn drives the second conveyor belt 38. The support roller 39 provides stable support for the second conveyor belt 38 to prevent it from sagging due to the weight of the material. During conveying, the limiting baffle 315 restricts the finished product. When the position of the limiting baffle 315 needs to be adjusted, the third threaded rod 312 is rotated by rotating the adjusting knob 313, which causes the sliding support rod 314 to slide inside the third fixed seat 311, thereby adjusting the position of the limiting baffle 315. After the finished product is conveyed to the first mounting bracket 21, it falls onto the first conveyor belt 214. The weight of the material is detected by the weighing sensor body 217 and the signal is transmitted to the controller. At body 226, if the material weight meets the standard, the controller body 226 controls the third motor 212 to drive the first conveyor roller 213 to rotate forward, driving the first conveyor belt 214 to transport the material to the qualified area; if the weight does not meet the standard, the third motor 212 drives the first conveyor roller 213 to rotate, transporting the material to the corresponding unqualified area, completing the automated sorting. After weighing, when the sorting component needs to be cleaned, the first motor 23 drives the first threaded rod 24 to rotate, driving the sliding bracket 25 to slide along the first fixed bracket 22. At the same time, the second motor 26 drives the second threaded rod 27 to rotate, driving the sliding seat 28 to move on the sliding bracket 25. During the movement of the sliding seat 28, the fixed rack 210 meshes with the first gear 211 on the first cleaning roller 29, causing the first cleaning roller 29 to rotate in the trough to clean the sorting work and prevent it from affecting the weighing component's weighing. During the weighing process, when subjected to external vibration or impact, the first rotating rod 222 and the second rotating rod 223 between the first mounting base 218 and the second mounting base 219 drive the second sliding block 221 to slide on the first connecting bracket 220. In conjunction with the elastic deformation of the first spring 225, part of the impact force is absorbed, and the damper body 224 further attenuates the vibration energy, reducing the impact of vibration on the weighing sensor body 217 and ensuring accurate weighing data.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
