Description

Technical Field

[0001] This utility model belongs to the field of chemical processing technology, and in particular relates to a metering device based on potassium humate and sodium humate. Background Technology

[0002] In the field of chemical production, potassium humate and sodium humate are important chemical raw materials and are widely used in agriculture, petroleum, medicine and other industries. In the manufacturing process of products involving potassium humate and sodium humate, accurate batching and metering are the key links to ensure product quality and performance, which requires efficient and reliable metering equipment.

[0003] However, existing metering equipment for potassium humate and sodium humate requires manual opening of the bag during use. As the number of metering operations increases, it can easily cause worker fatigue, leading to improper operation, metering errors, and rework. Utility Model Content

[0004] The purpose of this invention is to provide a metering device based on potassium humate and sodium humate. By setting up a bag-supporting mechanism, it solves the problem that existing metering devices for potassium humate and sodium humate require manual opening of the bag during use. As the number of metering operations increases, this can easily cause operator fatigue, leading to metering errors and rework due to improper operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a metering device based on potassium humate and sodium humate, including a base plate, on which a bag-supporting mechanism and a buckling mechanism are provided;

[0007] Two support frames are fixedly connected to the top of the base plate. A sliding rod is fixedly connected between the two support frames. A bidirectional threaded rod is rotatably connected between the two sliding rods. The left side of the bidirectional threaded rod passes through the support frame located on the left side. Two sliders are threadedly connected to the outer wall of the bidirectional threaded rod. The sliding rod passes through the two sliders and is slidably connected to the two sliders. A fixing block is fixedly connected to the side of the two sliders that are close to each other. The buckling mechanism includes a rectangular box fixedly connected to the outer wall of the bidirectional threaded rod.

[0008] Furthermore, an arc-shaped block is fixedly connected to the top of each of the two fixed blocks, and an arc-shaped groove is opened on the side of each of the two arc-shaped blocks that are far apart from each other. A knob is fixedly connected to the left side of the bidirectional threaded rod, and two support frames are fixedly connected to the top of the first support frame.

[0009] Furthermore, a storage tank is fixedly connected between the two support frames, a discharge pipe is connected to the bottom of the storage tank, a valve is provided on the outer wall of the discharge pipe, a feed pipe is connected to the top of the base plate, and an electronic scale is fixedly connected to the top of the base plate.

[0010] Furthermore, a telescopic rod is fixedly connected to the bottom inner wall of the rectangular box, a limit block is fixedly connected to the top of the telescopic rod, a spring is sleeved on the outer wall of the telescopic rod, the top of the spring is fixedly connected to the limit block, and the bottom of the spring is fixedly connected to the rectangular box.

[0011] Furthermore, a protective shell is fixedly connected to the left side of the support frame located on the left side, and the left side of the bidirectional threaded rod passes through the protective shell. The bidirectional threaded rod is rotatably connected to the protective shell, and a number of limiting grooves are opened on the inner wall of the protective shell. The number of limiting grooves are adapted to the limiting blocks.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a bag-supporting mechanism, after sufficient potassium humate and sodium humate are added to the storage tank through the feed pipe, the bag opening for weighing is fixed. The bag opening is bent and its edge is placed into the arc grooves on the two arc blocks. Then, the knob is rotated, which drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the two sliders to move away from each other under the limit of the sliding rod. Thus, the two sliders drive the two arc blocks to move away from each other through the two fixed blocks. The two arc grooves also move away from each other as the two arc blocks move away, thereby expanding the edge of the bag opening. When it is large enough to catch the material falling from the discharge pipe, the bidirectional threaded rod is stopped. At this time, the two arc blocks will expand the bag opening without providing support for measurement. When the valve is opened, the discharge pipe starts to discharge. The weight of the material in the bag can be determined by observing the reading of the electronic scale, thus completing the measurement. This allows for automatic expansion of the bag opening, making the operation easy and convenient. This reduces the labor intensity of the operator and reduces measurement errors and rework caused by improper operation due to fatigue.

[0014] 2. By setting up a snap-fit ​​mechanism, when the bidirectional threaded rod rotates, the rectangular box on it will also rotate, thereby driving the limiting block to rotate around the bidirectional threaded rod. The corresponding limiting groove squeezes the limiting block, making it move closer to the bidirectional threaded rod, thereby squeezing the telescopic rod and spring, causing them to contract, until the limiting block slides into the next limiting groove. The limiting block is then reset under the action of the spring, thus locking the limiting block into the limiting groove. This prevents the bag-supporting mechanism from rotating in its natural state, thus preventing accidental rotation of the bag-supporting mechanism and avoiding bag opening position deviation, which could cause the potassium humate and sodium humate ingredients falling from the discharge pipe to not accurately fall into the bag, resulting in measurement errors.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0026] Please see Figure 1-6 As shown, this utility model is a metering device based on potassium humate and sodium humate. It includes a base plate 1, on which a bag-supporting mechanism 2 and a buckling mechanism 3 are mounted. Two support frames 111 are fixedly connected to the top of the base plate 1. A sliding rod 211 is fixedly connected between the two support frames 111. A bidirectional threaded rod 212 is rotatably connected between the two sliding rods 211. The left side of the bidirectional threaded rod 212 passes through the support frame 111 located on the left side. Two sliders 213 are threadedly connected to the outer wall of the bidirectional threaded rod 212. The sliding rod 211 passes through the two sliders 213, and the sliding rod 211 is slidably connected to the two sliders 213. A fixing block 214 is fixedly connected to the side of each slider 213 that is close to each other. The top of each fixing block 214 is fixed... An arc-shaped block 215 is connected, and an arc-shaped groove 216 is opened on the side of the two arc-shaped blocks 215 that are far apart from each other. A knob 217 is fixedly connected to the left side of the bidirectional threaded rod 212. Two support frames 112 are fixedly connected to the top of the support frame 111. A storage tank 113 is fixedly connected between the two support frames 112. A discharge pipe 114 is connected to the bottom of the storage tank 113. A valve 115 is provided on the outer wall of the discharge pipe 114. A feed pipe 116 is connected to the top of the bottom plate 1. An electronic scale 117 is fixedly connected to the top of the bottom plate 1. By setting the bag-supporting mechanism 2, the bag opening can be automatically expanded, making the operation easy and convenient, thereby reducing the labor intensity of the operator and reducing the measurement error and rework caused by improper operation due to fatigue.

[0027] The buckling mechanism 3 includes a rectangular box 311 fixedly connected to the outer wall of the bidirectional threaded rod 212. A telescopic rod 312 is fixedly connected to the bottom inner wall of the rectangular box 311. A limiting block 313 is fixedly connected to the top of the telescopic rod 312. A spring 314 is sleeved on the outer wall of the telescopic rod 312. The top of the spring 314 is fixedly connected to the limiting block 313, and the bottom of the spring 314 is fixedly connected to the rectangular box 311. A protective shell 315 is fixedly connected to the left side of the support frame 111 located on the left side. The left side of the bidirectional threaded rod 212 passes through the protective shell 315. The bidirectional threaded rod 212 and the protective shell 315 are rotatably connected. Several limiting grooves 316 are opened on the inner wall of the protective shell 315. The several limiting grooves 316 are adapted to the limiting block 313. By setting the buckling mechanism 3, the bag-supporting mechanism 2 can be prevented from rotating accidentally, thereby avoiding the bag opening position deviation, which would prevent the potassium humate and sodium humate ingredients falling from the discharge pipe from accurately falling into the bag and causing measurement errors.

[0028] A specific application of this embodiment is as follows: In use, firstly, sufficient amounts of potassium humate and sodium humate are added to the storage tank 113 through the feed pipe 116. Then, the bag opening for weighing the ingredients is fixed, the bag opening is bent, and its edge is placed into the arc grooves 216 on the two arc blocks 215. Then, the knob 217 is turned, which drives the bidirectional threaded rod 212 to rotate. The rotation of the bidirectional threaded rod 212 causes the two sliders 213 to move away from each other under the limit of the slide rod 211. Thus, the two sliders 213 respectively drive the two arc blocks 215 to move away from each other through the two fixing blocks 214. The two arc grooves 216 also move away from each other as the two arc blocks 215 move away. The valve 115 opens the bag opening, causing the edge to expand sufficiently to catch the material falling from the discharge pipe 114. The double-ended threaded rod 212 then stops rotating. At this point, the two arc-shaped blocks 215 expand the bag opening without providing sufficient support for measurement. When the valve 115 is opened, the discharge pipe 114 begins to discharge material. Observing the reading on the electronic scale 117 reveals the mass of the material in the bag, thus completing the measurement. The electronic scale 117 uses a strain gauge load cell, a high-precision anti-shake counting electronic scale from Rongcheng. Its working principle is as follows: when an object is placed on the weighing platform, the platform pressure causes the elastic body to deform, changing the resistance value of the strain gauge. This change is converted into a voltage signal by a Wheatstone bridge and amplified by an amplifier. To ensure measurement accuracy, it is equipped with shock absorption devices and anti-interference circuits in hardware, and digital filtering technology in software to remove noise such as external vibrations and electromagnetic interference. During counting, the average weight of a single object is first calculated, and then the total weight is used to calculate the number of objects. The processed signal is transmitted to the microprocessor, where it is converted into weight and count values ​​and finally displayed on the screen. The microprocessor also supports unit conversion and other functions. When the bidirectional threaded rod 212 rotates, the rectangular box 311 on it also rotates, thereby driving the limiting block 313 to rotate around the bidirectional threaded rod 212. The corresponding limiting groove 316 squeezes the limiting block 313, making it move closer to the bidirectional threaded rod 212, thereby squeezing the telescopic rod 312 and the spring 314, causing them to retract, until the limiting block 313 slides into the next limiting groove 316. The limiting block 313 is reset under the action of the spring 314, so that the limiting block 313 is locked into the limiting groove 316 to prevent the bag-supporting mechanism 2 from rotating in its natural state.
