Description

Technical Field

[0001] This application relates to the field of fertilizer production and processing technology, and in particular to a high-efficiency weighing and filling system. Background Technology

[0002] Quantitative filling is a crucial step in ensuring product quality and meeting market demands. To ensure that the weight of each can of fertilizer meets standards, it is necessary to accurately weigh the fertilizer cans during or after filling. Traditional filling production lines are usually equipped with independent weighing equipment to check the weight of the filled fertilizer cans, thereby controlling the product weight and ensuring smooth operation in subsequent warehousing, transportation, and sales. These weighing devices, as an important component of the filling production line, directly affect production efficiency and product quality.

[0003] However, traditional weighing equipment requires manual handling to move the filled fertilizer tanks from the filling station to the weighing platform. This process not only consumes a lot of manpower and increases the labor intensity of workers, but also limits the overall production efficiency due to the rhythm of manual operation, making it difficult to meet the needs of large-scale and automated production. At the same time, existing weighing platforms generally do not have limiting structures for fertilizer tanks. The placement of fertilizer tanks on the weighing platform depends entirely on manual experience, which is prone to deviation or tilting. Furthermore, during the filling process, the impact of falling material or slight external vibrations may cause fertilizer tanks to shake or even tip over, which not only affects the accuracy of the weighing results, but may also cause material spillage, further reducing production efficiency and increasing material loss. Utility Model Content

[0004] The purpose of this application is to provide an efficient weighing and filling system that limits the main body of the fertilizer tank, effectively preventing instability during filling and avoiding tilting or tipping. At the same time, the electrically controlled valve, flow meter and weighing device are linked through an external controller to achieve precise control of the filling volume, thus solving the problems mentioned in the background art.

[0005] This application provides a high-efficiency weighing and filling system with the following technical solution: It includes a weighing device, an installation frame fixedly mounted on the upper side of the weighing device, multiple sliding rollers rotatably connected to the inner side of the installation frame, a fertilizer tank body placed on the upper side of the sliding rollers, a clamping assembly provided on the inner side of the installation frame, a rotating shaft rotatably connected to the inner side of the installation frame, the clamping assembly including a first gear fixedly connected to the outer side of the rotating shaft, two symmetrical first racks meshing with the outer side of the first gear, a connecting frame fixedly connected to one end of each of the two first racks, a clamping plate fixedly connected to the upper side of each of the two connecting frames, the two clamping plates being symmetrically arranged, a driving assembly provided on the inner side of the installation frame, a filling pipe provided above the installation frame, an electrically controlled valve fixedly mounted on the outer side of the filling pipe, a flow meter fixedly mounted on the outer side of the filling pipe, and a conveyor belt device provided on one side of the installation frame.

[0006] By adopting the above technical solution, the main body of the fertilizer tank placed on the sliding roller can be weighed directly by setting up a weighing device, eliminating the need for manual handling, saving manpower and improving production efficiency. Then, the first gear and first rack in the clamping assembly drive the clamping plate to limit and fix the main body of the fertilizer tank, solving the problem of insufficient stability. At the same time, the electric control valve and flow meter on the outside of the injection pipe work with the weighing device to achieve accurate filling. Afterwards, the sliding roller and the conveyor belt equipment work together to realize the automatic transfer of the main body of the fertilizer tank, further improving the degree of automation.

[0007] Preferably, the clamping assembly further includes two guide rails fixedly connected to the inner side of the mounting frame, and the outer sides of the two connecting brackets are slidably connected to the inner sides of the two guide rails respectively.

[0008] By adopting the above technical solution, the guide rail provides guidance for the connecting frame, ensuring that the clamping plate remains stable during movement, avoiding the impact of deviation on the clamping effect on the main body of the fertilizer tank, and improving the operational stability of the clamping assembly.

[0009] Preferably, protective pads are fixedly connected to the sides of the two clamping plates that are close to each other, and the protective pads are made of rubber.

[0010] By adopting the above technical solution, the protective pad made of rubber material can avoid direct rigid contact between the clamping plate and the main body of the fertilizer tank, which can not only protect the main body of the fertilizer tank from damage, but also increase the friction of the contact surface and further improve the stability of clamping.

[0011] Preferably, the bottom surfaces of both clamping plates are fixedly connected to auxiliary support frames, and the outer sides of the two auxiliary support frames are slidably connected to the inner sides of the two guide rails respectively.

[0012] By adopting the above technical solution, the auxiliary support frame is slidably connected to the guide rail, providing additional support for the clamping plate and preventing the clamping plate from deforming or tilting due to force during clamping, thus ensuring the stability of clamping.

[0013] Preferably, the drive assembly includes a second gear and a first pneumatic telescopic rod. The inner side of the second gear is fixedly connected to the outer side of the rotating shaft, and the outer side of the first pneumatic telescopic rod is fixedly connected to the inner side of the mounting frame. A fixing block is fixedly connected to the output end of the first pneumatic telescopic rod, and a second rack is fixedly connected to the outer side of the fixing block. The second rack and the second gear mesh with each other.

[0014] By adopting the above technical solution, the first pneumatic telescopic rod drives the second rack to move, and then drives the rotating shaft to rotate through the second gear, realizing the automated control of the clamping component without manual operation, thus improving the automation level and ease of operation of the equipment.

[0015] Preferably, the electrically controlled valve, the flow meter, and the weighing device are all electrically connected to an external controller.

[0016] By adopting the above technical solution, an external controller can receive the detection data from the weighing device and flow meter, and control the opening of the electric control valve according to the preset program to achieve precise control of the filling volume and ensure that the filling weight of the fertilizer tank body meets the standard.

[0017] Preferably, a fixing frame is fixedly connected to the outer side of the mounting frame, and a second pneumatic telescopic rod is fixedly connected to the outer side of the fixing frame. The output end of the second pneumatic telescopic rod extends through the inner side of the fixing frame to the outside, and a push block is fixedly connected to the output end of the second pneumatic telescopic rod.

[0018] By adopting the above technical solution, the second pneumatic telescopic rod can drive the pusher block to push the weighed fertilizer tank body from the sliding roller to the conveyor belt equipment, thereby realizing the automatic transfer of the fertilizer tank body, avoiding manual handling, and further improving production efficiency.

[0019] Preferably, the position of the sliding roller is on the same horizontal plane as the position of the internal conveyor belt of the conveyor belt device.

[0020] By adopting the above technical solution, the sliding roller and the conveyor belt of the conveyor belt equipment are on the same horizontal plane, ensuring that the main body of the fertilizer tank can be smoothly transferred during the transfer process, and avoiding tilting of the main body of the fertilizer tank or leakage of materials due to height difference.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This high-efficiency weighing and filling system uses a clamping assembly with a first gear and a first rack to drive the clamping plate and limit the main body of the fertilizer tank, effectively preventing instability during filling and avoiding tilting or tipping, thus ensuring the filling stability of the fertilizer tank. Then, the clamping action is automatically controlled by the first pneumatic telescopic rod, the second rack, and the second gear in the drive assembly. Subsequently, the electrically controlled valve, flow meter, and weighing device are linked through an external controller to achieve precise control of the filling volume, comprehensively improving the system's automation level, weighing accuracy, and production stability.

The clamping assembly 5 also includes two guide rails 507 fixedly connected to the inner side of the mounting frame 2, and two connecting brackets 503... The outer sides of the 03 are slidably connected to the inner sides of the two guide rails 507.

Protective pads 505 are fixedly connected to the sides of the two clamping plates 504 that are close to each other. The protective pads 505 are made of rubber, which can prevent the clamping plate 504 from contacting the fertilizer tank body 4. Direct rigid contact not only protects the fertilizer tank body 4 from damage, but also increases the friction of the contact surface, further improving the stability of clamping. The bottom surfaces of the two clamping plates 504 are fixedly connected to auxiliary support frames 506. The outer sides of the two auxiliary support frames 506 are slidably connected to the inner sides of the two guide rails 507. The auxiliary support frames 506 and the guide rails 507 are slidably connected to provide additional support for the clamping plates 504, preventing the clamping plates 504 from deforming or tilting due to force during clamping, thus ensuring the stability of clamping.

[0026] Please refer to Figure 1 , Figure 2 and Figure 5A drive assembly 7 is provided on the inner side of the mounting frame 2. The drive assembly 7 includes a second gear 701 and a first pneumatic telescopic rod 703. The inner side of the second gear 701 is fixedly connected to the outer side of the rotating shaft 6, and the outer side of the first pneumatic telescopic rod 703 is fixedly connected to the inner side of the mounting frame 2. A fixing block 704 is fixedly connected to the output end of the first pneumatic telescopic rod 703, and a second rack 702 is fixedly connected to the outer side of the fixing block 704. The second rack 702 meshes with the second gear 701. The first pneumatic telescopic rod 703 drives the second rack 702 to move, which in turn drives the rotating shaft 6 to rotate through the second gear 701, thereby realizing the clamping assembly. The automated control of component 5 eliminates the need for manual operation, improving the automation level and ease of operation of the equipment. An injection pipe 8 is installed above the mounting frame 2, and an electrically controlled valve 9 is fixedly installed on the outside of the injection pipe 8. A flow meter 10 is also fixedly installed on the outside of the injection pipe 8. A conveyor belt device 11 is installed on one side of the mounting frame 2. The electrically controlled valve 9, the flow meter 10, and the weighing device 1 are all electrically connected to an external controller. The external controller can receive the detection data from the weighing device 1 and the flow meter 10, and control the opening degree of the electrically controlled valve 9 according to the preset program to achieve precise control of the filling volume and ensure that the filling weight of the fertilizer tank body 4 meets the standard.

[0027] Example 2: A high-efficiency weighing and filling system, please refer to... Figure 1 , Figure 2 and Figure 3 A fixed frame 12 is fixedly connected to the outer side of the mounting frame 2. A second pneumatic telescopic rod 13 is fixedly connected to the outer side of the fixed frame 12. The output end of the second pneumatic telescopic rod 13 extends through the inner side of the fixed frame 12 to the outside. A push block 14 is fixedly connected to the output end of the second pneumatic telescopic rod 13. The second pneumatic telescopic rod 13 drives the push block 14 to push the weighed fertilizer tank body 4 from the sliding roller 3 to the conveyor belt equipment 11, realizing the automatic transfer of the fertilizer tank body 4, avoiding manual handling, and further improving production efficiency. The position of the sliding roller 3 is at the same horizontal plane as the position of the internal conveyor belt of the conveyor belt equipment 11. The sliding roller 3 and the conveyor belt of the conveyor belt equipment 11 are at the same horizontal plane to ensure that the fertilizer tank body 4 can be smoothly transferred during the transfer process, avoiding tilting of the fertilizer tank body 4 or material spillage due to height difference.

[0028] The implementation principle of this application embodiment is as follows: When this weighing and filling device is working, the fertilizer tank body 4 is first placed on the sliding roller 3. At this time, the first pneumatic telescopic rod 703 in the drive assembly 7 pushes the second rack 702 to move, driving the second gear 701 and the rotating shaft 6 to rotate. At this time, the rotation of the rotating shaft 6 drives the first gear 501 to rotate. Then, the first gear 501 drives the two first racks 502 to move relative to each other. Then, the movement of the first racks 502 drives the connecting frame 503 to drive the clamping plate 504 to clamp and fix the fertilizer tank body 4. At the same time, the rubber material of the protective pad 505 can enhance the clamping stability and protect the tank body. Then, during filling, the injection pipe 8 injects into the fertilizer tank body 4. Material is injected, and the flow meter 10 detects the filling flow rate in real time and feeds it back to the controller. At the same time, the electric valve 9 adjusts its opening according to the flow data. Meanwhile, the weighing device 1 detects the total weight of the fertilizer tank body 4 in real time. When the weight is close to the preset value, the controller controls the electric valve 9 to reduce its opening. When the preset value is reached, the valve is closed to achieve accurate filling. After filling is completed, the clamping assembly 5 releases the fertilizer tank body 4, and the second pneumatic telescopic rod 13 drives the push block 14 to push the fertilizer tank body 4 from the sliding roller 3 to the conveyor belt device 11 to complete the automatic transfer. At the same time, the sliding roller 3 and the conveyor belt of the conveyor belt device 11 are on the same horizontal plane to ensure that the fertilizer tank body 4 can be smoothly transferred during the transfer process.
