TECHNICAL FIELD
[0001] The utility model relates to a weighing hopper, in particular to a lower hopper and a lower discharging device with weighing function. BACKGROUND
[0002] When the material is weighed at the discharging end of the lower hopper, due to the difference in flowability of the material, the form accumulated by the weight of the material itself is also different; during the discharging process, the vibration of the lower hopper and the surrounding equipment will be transmitted to the weighing device, the weighing device is affected by the vibration, the stability of the weighing is poor; the impact force generated when the material is discharged from the lower hopper directly acts on the weighing device, which causes interference to the weighing device, resulting in fluctuation of the weighing result. SUMMARY
[0003] The utility model discloses a lower hopper and a lower discharging device with weighing function, and aims to solve the technical problem of how to improve the accuracy of the weighing result of the lower hopper.
[0004] The utility model discloses the following technical scheme:
[0005] The first aspect provides a lower hopper, which comprises a warehouse body and a material rack, and the material rack is arranged below the warehouse body.
[0006] The material stacking plate, the weighing plate and the discharging plate are embedded on the material rack.
[0007] The warehouse body is provided with a material guide pipe, and the discharging end of the material guide pipe is located directly above the material stacking plate.
[0008] The first pushing assembly reciprocates between the material stacking plate and the weighing plate, and the second pushing assembly reciprocates between the weighing plate and the discharging plate.
[0009] By embedding the material stacking plate, the weighing plate and the discharging plate on the material rack, the clear partition of the material from receiving, weighing to discharging is realized, the weighing error and the result fluctuation caused by the impact of the material on the weighing plate during the weighing process are effectively avoided, and the accuracy of the weighing result of the lower hopper is improved.
[0010] The material guide pipe arranged on the bin body has a discharging end located directly above the material stacking plate, which ensures that the material can fall on the material stacking plate and reduces the scattering and deviation of the material during the conveying process; the first pushing assembly and the second pushing assembly are introduced to respectively push the material between the material stacking plate and the weighing plate and between the weighing plate and the discharging plate; the weighing plate is a region specially used for weighing, and the first pushing assembly pushes the material from the material stacking plate to the weighing plate, which reduces the dynamic interference of the material discharging on the weighing plate during the weighing process and improves the stability of the weighing result.
[0011] Further, the lower surface of the weighing plate is provided with a clamping groove, and the groove wall of the clamping groove is attached with a buffer;
[0012] The clamping groove is clamped on the material rack, and the buffer is attached to the material rack.
[0013] The weighing plate is tightly connected with the material rack through the clamping groove, which reduces the displacement of the weighing plate; the buffer reduces the interference of the external environment and devices (such as vibration, airflow, etc.) on the weighing result; when the material is pushed onto the weighing plate, or when the weighing plate is subjected to other external forces, the buffer can absorb and disperse these impact and vibration energy, preventing the impact and vibration from being directly transmitted to the weighing device, which helps to maintain the stability of the weighing plate and reduces the weighing error; by reducing the impact, vibration and displacement of the weighing plate during the weighing process, the accuracy of the weighing result is improved.
[0014] Further, the buffer extends to the upper surface of the weighing plate, and the end of the buffer extending out of the upper surface of the weighing plate is connected with a first limiting block;
[0015] The first limiting block is symmetrical about the connecting line of the first limiting block and the buffer;
[0016] The lower surface of the first limiting block is attached to the upper surfaces of the weighing plate, the material stacking plate and the discharging plate;
[0017] When the first limiting block extends from the symmetry line to both ends, the thickness of the first limiting block gradually decreases.
[0018] The buffer is not only attached to the slot wall of the weighing plate, but also extends upward and connects the first limiting block, the lower surface of the first limiting block is attached to the upper surfaces of the weighing plate, the material stacking plate and the discharging plate, further enhancing the buffering effect; when the material contacts the weighing plate or is subjected to other external forces, the buffer can more effectively absorb and disperse impact and vibration energy, reducing their impact on the weighing system; the first limiting block limits the weighing plate, the material stacking plate and the discharging plate in the same plane, avoiding material impact and vibration caused by the falling of the material when the first pushing assembly pushes the material; since the thickness of the first limiting block gradually decreases when extending from the center line to both ends, the connection of the weighing plate, the material stacking plate and the discharging plate is smoother, facilitating the pushing of the first pushing assembly and the second pushing assembly.
[0019] Further, the buffer extends to the lower surface of the weighing plate, and the end of the buffer extending out of the lower surface of the weighing plate is connected with the second limiting block.
[0020] The second limiting block is attached to the lower surfaces of the weighing plate and the material rack.
[0021] The first limiting block is attached to the upper surfaces of the weighing plate, the material stacking plate and the discharging plate, and the second limiting block is attached to the lower surfaces of the weighing plate and the material rack, further reducing the vibration and displacement of the weighing plate during weighing, and improving the stability and accuracy of the weighing result; during long-term use, due to factors such as vibration, impact or temperature change, the connection between the weighing plate and the material rack may loosen, and since the first limiting block and the second limiting block ensure that the weighing plate always remains in the correct position, the weighing error caused by loosening of the weighing plate is avoided.
[0022] Further, the buffer, the first limiting block and the second limiting block are made of rubber.
[0023] The buffer, the first limiting block and the second limiting block made of rubber can absorb and disperse impact, vibration and other energy, reducing their impact on the weighing system, thereby improving the accuracy of the weighing result.
[0024] Further, the first pushing assembly and the second pushing assembly each include a driver, a telescopic rod and a pushing plate.
[0025] The driver is arranged on the material rack.
[0026] One end of the telescopic rod is connected to the output shaft of the driver, and the other end of the telescopic rod is connected to the pushing plate.
[0027] The lower surface of the pushing plate on the first pushing assembly contacts the material stacking plate, and the pushing plate is used to push the material to the weighing plate through the gap between the discharging end of the material guide pipe and the material stacking plate.
[0028] The lower surface of the push plate on the second push assembly is in contact with the weighing plate, and the push plate is used to push the material to the discharging plate.
[0029] The telescopic movement of the telescopic rod is driven by the driver, the moving distance and speed of the push plate are controlled, and the accurate transfer of the material between the material stacking plate, the weighing plate and the discharging plate is ensured.
[0030] Further, the upper surface of the stacking plate on the first push assembly is provided with a baffle;
[0031] When the push plate moves to the weighing plate, the baffle is driven to be located directly below the discharging end of the material guide pipe, and the discharging end of the material guide pipe is blocked.
[0032] When the push plate starts to push the material, the baffle gradually blocks the discharging end of the material guide pipe, so that the falling material cannot flow into the weighing plate, and the material impact is prevented, so that the weighing result is not accurate.
[0033] The second aspect provides a discharging device with a weighing function, comprising a weighing sensor and the above-mentioned discharging hopper.
[0034] The weighing sensor is arranged at the bottom of the weighing plate, and the weighing sensor is used to monitor and feed back the weight information of the material in real time.
[0035] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0036] By embedding the material stacking plate, the weighing plate and the discharging plate on the material rack, the clear partition of the material from receiving, weighing to discharging is realized, the weighing error and result fluctuation caused by the impact of the material on the weighing plate during the weighing process are effectively avoided, and the accuracy of the weighing result of the discharging hopper is improved.
[0037] The material guide pipe arranged on the bin body has a discharging end located directly above the material stacking plate, which ensures that the material can fall on the material stacking plate and reduces the scattering and deviation of the material during the conveying process; the first pushing assembly and the second pushing assembly are introduced to push the material between the material stacking plate and the weighing plate and between the weighing plate and the discharging plate respectively; the weighing plate is a region specially used for weighing, and the first pushing assembly pushes the material from the material stacking plate to the weighing plate, which reduces the dynamic interference of the material discharging on the weighing plate during the weighing process and improves the stability of the weighing result.

[0051] By embedding the material stacking plate 6, the weighing plate 7 and the discharging plate 12 on the material rack 5, the material is clearly divided into receiving, weighing and discharging zones, effectively avoiding weighing errors and result fluctuations caused by excessive pressure exerted on the weighing plate 7 by material impact during weighing, and improving the accuracy of the weighing result of the discharging hopper.

[0053] Embodiment 2
[0054] Based on embodiment 1, in combination Figure 1 The lower surface of the weighing plate 7 is provided with a clamping groove, and the groove wall of the clamping groove is attached with a buffer 9;
[0055] The clamping groove is clamped on the material rack 5, and the buffer 9 is attached to the material rack 5.
[0056] A reference application scenario, for chemical, pharmaceutical, food and other industries need high precision weighing, the above weighing plate 7 is connected with the material rack 5 through the clamping groove, the clamping mode reduces the displacement of the weighing plate 7 caused by loose connection or vibration, and the accuracy of weighing is improved; the buffer 9 reduces the interference of external environment and device (such as vibration, airflow, etc.) on the weighing result; when the material is pushed onto the weighing plate 7, or when the weighing plate 7 is subjected to other external force, the buffer 9 can absorb and disperse the impact and vibration energy, prevent the impact and vibration from being directly transmitted to the weighing device, help to keep the stability of the weighing plate 7, and further reduce the weighing error; by reducing the impact, vibration and displacement of the weighing plate 7 during weighing, the precision of the weighing result is improved. The clamping groove and the buffer 9 also simplify the installation and maintenance process of the weighing plate 7, the clamping mode enables the weighing plate 7 to be quickly and accurately installed on the material rack 5, and the replacement and maintenance of the buffer 9 are relatively simple, which reduces the maintenance cost and time.
[0057] In particular embodiments, in combination Figure 3 The buffer 9 extends to the upper surface of the weighing plate 7, and the end of the buffer 9 extending out of the upper surface of the weighing plate 7 is connected with the first limiting block 10;
[0058] The first limiting block 10 is symmetrical about the connecting line of the first limiting block 10 and the buffer 9;
[0059] The lower surface of the first limiting block 10 is attached to the upper surfaces of the material rack 5, the weighing plate 7, the material stacking plate 6 and the discharging plate 12;
[0060] When the first limiting block 10 extends from the symmetry line to both ends, the thickness of the first limiting block 10 gradually decreases.
[0061] The buffer 9 not only is attached to the slot wall of the clamping groove of the weighing plate 7, but also extends upward and connects the first limiting block 10, the lower surface of the first limiting block 10 is attached to the upper surfaces of the weighing plate 7, the material stacking plate 6 and the discharging plate 12, and the buffering effect is further enhanced; when the material contacts the weighing plate 7 or is subjected to other external force, the buffer 9 can more effectively absorb and disperse the impact and vibration energy, reducing their influence on the weighing system; the weighing plate 7, the material stacking plate 6 and the discharging plate 12 are limited in the same plane by the first limiting block 10, avoiding the impact and vibration caused by the falling of the material when the first pushing assembly 3 pushes the material; since the thickness of the first limiting block 10 gradually decreases when it extends from the symmetry line to both ends, the connection of the weighing plate 7, the material stacking plate 6 and the discharging plate 12 is smoother, facilitating the pushing of the first pushing assembly 3 and the second pushing assembly 4.
[0062] Example 3
[0063] On the basis of example 2, in combinationFigure 3 The buffer 9 extends to the lower surface of the weighing plate 7, and the end of the buffer 9 extending out of the lower surface of the weighing plate 7 is connected with the second limiting block 11.
[0064] The second limiting block 11 is attached to the lower surfaces of the weighing plate 7 and the material rack 5.
[0065] The first limiting block 10 is attached to the upper surfaces of the weighing plate 7, the material stacking plate 6, and the discharging plate 12, and the second limiting block 11 is attached to the lower surfaces of the weighing plate 7 and the material rack 5. Through double limiting, the vibration and displacement of the weighing plate 7 during weighing are further reduced, and the stability and accuracy of the weighing result are improved. During long-term use, the connection between the weighing plate 7 and the material rack 5 may be loose due to factors such as vibration, impact, or temperature change. Since the first limiting block 10 and the second limiting block 11 ensure that the weighing plate 7 always remains in the correct position, weighing errors caused by the loosening of the weighing plate 7 are avoided.
[0066] The first limiting block 10 provides a buffer for the upper surface of the weighing plate 7, the second limiting block 11 provides a buffer for the lower surface of the weighing plate 7, and the buffer 9 provides a buffer for the side wall of the weighing plate 7. This all-around buffering design can more effectively absorb and disperse impact and vibration energy, protect the weighing plate 7 and the material rack 5 from damage, further reduce the impact of vibration on the weighing plate 7, and thus improve the weighing accuracy.
[0067] In a specific embodiment, the buffer 9, the first limiting block 10, and the second limiting block 11 are made of rubber, which can be any one or more of natural rubber, styrene-butadiene rubber, nitrile rubber, and silicone rubber.
[0068] The buffer 9, the first limiting block 10, and the second limiting block 11 made of rubber can absorb and disperse impact, vibration, and other energy, reducing their impact on the weighing system and thus improving the accuracy of the weighing result. The friction coefficient between rubber and metal or other materials is relatively stable, which helps to maintain stable contact between the material and the weighing plate 7 during weighing. A stable friction coefficient can reduce weighing errors caused by sliding or deviation and improve the weighing accuracy.
[0069] Embodiment 4
[0070] On the basis of any of the above embodiments, in combination with Figure 4 The first pushing assembly 3 and the second pushing assembly 4 each include a driver 31, a telescopic rod 32, and a pushing plate 33. The driver 31 can be a hydraulic cylinder.
[0071] The driver 31 is arranged on the material rack 5.
[0072] One end of the telescopic rod 32 is connected to the output shaft of the driver 31, and the other end of the telescopic rod 32 is connected to the push plate 33.
[0073] The lower surface of the push plate 33 on the first push assembly 3 contacts the material stacking plate 6, and the push plate 33 is used to push the material through the gap between the discharge end of the material guide pipe 2 and the material stacking plate 6 to the weighing plate 7.
[0074] The lower surface of the push plate 33 on the second push assembly 4 contacts the weighing plate 7, and the push plate 33 is used to push the material to the discharging plate 12; the discharging plate 12 is inclined downward from one end close to the weighing plate 7, facilitating discharging.
[0075] The telescopic movement of the telescopic rod 32 is driven by the driver 31, the moving distance and speed of the push plate 33 are controlled, and the accurate transfer of the material between the material stacking plate 6, the weighing plate 7 and the discharging plate 12 is ensured; the push plate 33 directly contacts the material, so that the material can be smoothly pushed to the target position, reducing the splashing of the material during movement and the vibration and impact caused by the movement of the material, thereby reducing the influence on the weighing system and improving the stability and accuracy of the weighing result.
[0076] In a specific embodiment, the upper surface of the stacking plate on the first push assembly 3 is provided with a baffle 34.
[0077] When the push plate 33 moves to the weighing plate 7, the baffle 34 is driven to move directly below the discharge end of the material guide pipe 2, blocking the discharge end of the material guide pipe 2.
[0078] When the push plate 33 starts to push the material, the baffle 34 gradually blocks the discharge end of the material guide pipe 2, preventing the falling material from flowing into the weighing plate 7 and causing material impact, resulting in inaccurate weighing results; without the baffle 34, when the push plate 33 of the first push assembly 3 extends to the weighing plate 7, the material in the material guide pipe 2 continuously falls, and the material accumulates behind the push plate 33; when the telescopic rod 32 retracts the push plate 33 to the material stacking plate, the material accumulated behind the push plate 33 is pushed into the connecting gap between the material stacking plate and the material rack 5, not only causing material loss, but also increasing the workload of cleaning and maintenance.
