Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of platform scale testing equipment, and in particular to a double-platform buffer scale. Background Technology
[0002] Weighing is an essential step in industrial production, logistics sorting, and warehouse management. Especially in automated production lines or high-speed sorting systems, items typically enter the weighing area from upstream equipment (such as conveyor belts) at a relatively high speed.
[0003] In industrial production, logistics sorting, and warehousing management, there are large quantities of raw materials packaged in rolls. High-speed moving items directly impact the weighing platform, generating significant mechanical shock and vibration. This impact not only affects the measurement accuracy of the weighing sensors, leading to unstable weighing results and increased errors, but also shortens the lifespan of the sensors and the scale structure. To reduce damage from the impact, workers often control the speed and interval of item loading, which to some extent reduces overall operational efficiency and fails to meet the efficiency requirements of modern high-speed production lines. Therefore, a double-platform buffer scale is proposed. Utility Model Content
[0004] The main purpose of this utility model is to provide a double-platform buffer scale, which solves the problem that when high-speed moving items directly impact the weighing platform, they will generate large mechanical impacts and vibrations. This impact not only affects the measurement accuracy of the weighing sensor, leading to unstable weighing results and increased errors, but also shortens the service life of the sensor and scale structure. In order to reduce the damage caused by the impact, the staff often control the speed and interval of the items being put in, which to some extent reduces the overall work efficiency and cannot meet the efficiency requirements of modern high-speed production lines.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double-platform buffer scale includes a first weighing platform, four first connecting plates are fixedly connected at equal intervals above the first weighing platform, a limit sleeve is fixedly connected above each of the four first connecting plates, a buffer spring is fixedly connected above each of the four first connecting plates, a second connecting plate is fixedly connected above each of the four buffer springs, and a second weighing platform is fixedly connected above the four second connecting plates.
[0006] Furthermore, two guide blocks are fixedly connected at equal intervals above the second weighing platform. The two guide blocks are mirror images of each other, and a number of weight-reducing holes are equally spaced on the inner side of each guide block.
[0007] Furthermore, four mounting sleeves are fixedly connected at equal intervals inside the first weighing platform. Each of the four mounting sleeves is threaded with a threaded rod, and each of the four threaded rods is threaded with a first fixing nut. The bottom of each of the four first fixing nuts abuts against the first weighing platform.
[0008] Furthermore, four mounting plates are fixedly connected at equal intervals below the second weighing platform. Each of the four mounting plates has a limit hole at its bottom. The four threaded rods pass through the four limit holes respectively. Each of the four threaded rods is threaded with a second fixing nut at its top and a third fixing nut is fixedly connected to the outside of each of the four threaded rods.
[0009] Furthermore, four sensors are fixedly connected at equal intervals inside the first weighing platform. Each of the four sensors is fixedly connected to a support bracket at its lower end. Each of the four support brackets is fixedly connected to a fixed base on its outer side. Each of the four fixed bases is fixedly connected to a base plate below it. Each of the four fixed bases is fixedly connected to a reinforcing bracket. Each of the four fixed bases is threaded with two limit bolts at equal intervals on its outer side.
[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a buffer spring to buffer the impact force during weighing, increasing the equipment's lifespan without reducing the dispensing speed and improving work efficiency. When the weight roll is first placed on the second weighing platform, it impacts the platform. This impact force is transmitted to the buffer spring through the guide block, the second weighing platform, and the second connecting plate. The buffer spring and buffer pad effectively cushion the initial impact force, preventing damage to the sensor. This design effectively buffers the impact force during weighing, increasing the equipment's lifespan without reducing the dispensing speed and improving work efficiency.
[0011] This invention, through the use of a threaded rod, can limit the movement of the second weighing platform, preventing excessive shaking and equipment damage when the platform is impacted. When the weight roll is first placed on the second weighing platform, the impact causes the platform to shake. This shaking causes the mounting plate to vibrate, and the mounting plate is limited by the threaded rod, the second fixing nut, and the third fixing nut during this process. The mounting plate thus limits the position of the second weighing platform, preventing excessive shaking that could damage the equipment or affect the detection accuracy. This design effectively limits the movement of the second weighing platform, preventing excessive shaking and equipment damage when impacted.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figures 1-6 As shown, a double-platform buffer scale includes a first weighing platform 1. Four first connecting plates 2 are fixedly connected at equal intervals above the first weighing platform 1. Limiting sleeves 3 are fixedly connected above each of the four first connecting plates 2. Buffer springs 4 are fixedly connected above each of the four first connecting plates 2. Second connecting plates 21 are fixedly connected above each of the four buffer springs 4. A second weighing platform 13 is fixedly connected above each of the four second connecting plates 21. By adopting the above technical solution, the buffer springs 4 are springs with a large damping coefficient, which can effectively absorb the impact. Buffer pads are installed at the connection between the buffer springs 4 and the first connecting plates 2 to buffer the impact force.
[0022] Two guide blocks 14 are fixedly connected at equal intervals above the second weighing platform 13. The two guide blocks 14 are mirror images of each other. Several weight-reducing holes are equally spaced on the inner side of each guide block 14. By adopting the above technical solution, both guide blocks 14 are irregular shapes with side inclinations, and the positions of the inclined surfaces of the two guide blocks 14 are corresponding. This can guide the rolled-up weight placed between the two guide blocks 14, and the two guide blocks 14 can guide the weight to the middle position of the second weighing platform 13 for better weighing.
[0023] The first weighing platform 1 has four mounting sleeves 6 fixedly connected at equal intervals inside. Each of the four mounting sleeves 6 is threaded with a threaded rod 7. Each of the four threaded rods 7 is threaded with a first fixing nut 8 on the outside. The bottom of each of the four first fixing nuts 8 abuts against the first weighing platform 1. By adopting the above technical solution, the mounting sleeve 6 has a threaded groove inside, and the threaded rod 7 can be threaded into the mounting sleeve 6. The threaded rod 7 is made of high-strength material, which can effectively provide support and fixation.
[0024] Four mounting plates 12 are fixedly connected at equal intervals below the second weighing platform 13. Each of the four mounting plates 12 has a limit hole 11 at its bottom. The top of each of the four threaded rods 7 passes through the four limit holes 11. Each of the four threaded rods 7 is threaded with a second fixing nut 9. Each of the four threaded rods 7 is fixedly connected with a third fixing nut 10 on its outer side. By adopting the above technical solution, the four second fixing nuts 9 are respectively installed on the inner side of the four mounting plates 12, and the four third fixing nuts 10 are respectively installed on the outer side of the four mounting plates 12. The positions of the second fixing nuts 9 and the third fixing nuts 10 are relatively close, which can effectively limit the mounting plates 12 and prevent the mounting plates 12 from moving up and down excessively, thereby limiting the up and down movement of the second weighing platform 13. The sizes of the second fixing nut 9 and the third fixing nut 10 are designed so that the second fixing nut 9 and the third fixing nut 10 will not pass through the limiting hole 11; The diameter of the limiting hole 11 is slightly larger than that of the threaded rod 7. The threaded rod 7 can limit the mounting plate 12 through the limiting hole 11, thereby limiting the second weighing platform 13.
[0025] The first weighing platform 1 has four sensors 19 fixedly connected at equal intervals inside. The lower ends of the four sensors 19 are all fixedly connected to support brackets 18. The outer sides of the four support brackets 18 are all fixedly connected to fixed bases 16. The bottom of the four fixed bases 16 is fixedly connected to a base plate 15. The four fixed bases 16 are all fixedly connected to a reinforcing bracket 20. The outer sides of the four fixed bases 16 are all threaded with two limiting bolts 17 at equal intervals. By adopting the above technical solution, the limiting bolts 17 can play a limiting and guiding role, making it convenient for the first weighing platform 1 to be placed in the middle position of the space enclosed by the fixed bases 16 and the reinforcing brackets 20. The four sensors 19 are electrically connected to an external controller, which is able to collect the data detected by the sensors 19; The reinforced bracket 20 can provide enhanced support; The base plate 15 has mounting holes on its outer side, which can be used to fix the base plate 15 to the ground more stably with bolts.
[0026] It should be noted that during use, the base plate 15 is fixedly installed on a horizontal ground. When weighing is required, a crane is used to lift the weight roll or other items above the second weighing platform 13 and place it between the two guide blocks 14. When the weight falls, it is guided by the guide blocks 14 until the weight roll is stable in the middle of the two guide blocks 14 above the second weighing platform 13. At this time, the weight of the weight roll is transmitted to the third fixing nut 10 through the guide blocks 14, the second weighing platform 13 and the mounting plate 12. The third fixing nut 10 then transmits the weight to the sensor 19 through the threaded rod 7, the mounting sleeve 6 and the first weighing platform 1 to complete the detection.
[0027] When the weight roll is first placed on the second weighing platform 13, the weight roll will impact the second weighing platform 13. The impact force is transmitted to the buffer spring 4 through the guide block 14, the second weighing platform 13 and the second connecting plate 21. The buffer spring 4 and the buffer pad can buffer the impact force when it is first placed, and prevent the impact force from affecting the sensor 19 and causing damage to the sensor 19. Furthermore, when the weight roll is first placed on the second weighing platform 13, the impact of the weight roll will cause the second weighing platform 13 to shake. When the second weighing platform 13 shakes, it will cause the mounting plate 12 to shake. During the shaking process, the mounting plate 12 is limited by the threaded rod 7, the second fixing nut 9 and the third fixing nut 10. The mounting plate 12 then limits the position of the second weighing platform 13 to prevent the second weighing platform 13 from shaking excessively, causing equipment damage or affecting the detection accuracy. Furthermore, when the weight roll is placed on the second weighing platform 13, the guide block 14 can guide the weight roll to move to the middle position of the buffer scale, so that the center of gravity of the weight roll is close to the middle position of the buffer scale, thereby improving the measurement accuracy.
