[0039] A specific embodiment of the present application, as Figures 1-4 shown, discloses a nucleating agent crushing and sieving undersize recovery metering device, including a main cabinet body 30; a vibrating screen mechanism 20, arranged in the upper part of the main cabinet body 30; a plurality of storage boxes 40, respectively arranged in the main cabinet body 30 and located below the vibrating screen mechanism 20; an electric valve 50, arranged at the bottom of the storage box 40 for communicating and closing the inside and outside of the storage box 40; slide rails 60, respectively connected to the opposite side walls of the main cabinet body 30, and the storage box 40 is slidably connected to the slide rails 60; a pressure sensor, connected between the bottom of the storage box 40 and the slide rail bracket, and the storage box 40 is pressed on the pressure sensor so that the pressure sensor can measure the pressure value of the storage box 40; wherein, when the pressure sensor reaches a preset value range, the electric valve 50 is controlled to open.

[0040] In this embodiment, by directly connecting the main cabinet body 30 and the vibrating screen mechanism 20 below the crushing mechanism 10, the nucleating agent after being crushed by the crushing mechanism 10 directly falls onto the vibrating screen. After being screened by the vibrating screen mechanism 20, the undersize material that meets the requirements drops into the storage boxes 40 arranged below. When the undersize material continuously falls into the storage box 40, the pressure sensor measures the pressure value of the storage box 40, and the pressure sensor value between the bottom of the storage box 40 and the slide rail 60 changes continuously. When the pressure reaches the preset value range, the control electric valve 50 is opened to discharge the undersize material into the lower storage box 40. When the lower storage box 40 stores enough quantity, the electric valve 50 is opened again to let the material fall into the valve of the next lower layer. After the screening is completed, the storage box 40 can be taken out through the slide rail 60, and then the quantitatively measured nucleating agent is taken out. During this process, the amount of the nucleating agent in the storage box 40 can be controlled by the preset value. This device can realize the real-time metering of the undersize material after the nucleating agent is crushed and screened, avoiding the cumbersome process of subsequent pouring and metering, saving a large amount of packaging and classification time, and improving the production efficiency. The vibrating screen mechanism 20 can effectively screen the undersize material, improve the screening quality, and ensure that the purity and particle size of the undersize material meet the requirements. At the same time, the setting of multiple storage boxes 40 can classify and store the undersize materials of different batches or specifications, which is convenient for subsequent processing and use. The setting of the electric valve 50 can automatically control the opening and closing of the storage box 40 according to the measurement result of the pressure sensor, realizing accurate discharging and avoiding material waste. The slide rail 60 enables the storage box 40 to slide, which is convenient for taking out for cleaning and maintenance, and can also be flexibly adjusted according to the production requirements. The pressure sensor can accurately measure the pressure value of the storage box 40, providing a reliable basis for controlling the opening of the electric valve 50 and ensuring the accuracy of metering.

[0041] An electric valve 50 selected in this application mainly consists of the following parts: Valve body: Usually made of metal materials such as stainless steel, with channels inside for controlling the passage of materials. Valve stem: Connects the valve core and the electric actuator, transmitting power and motion. Valve core: Determines the opening and closing state of the valve.

[0042] Electric actuator: This is the power source of the electric valve 50, usually including a motor, a reducer, a control circuit, etc. The motor transmits the rotational motion to the valve stem through the reducer, thereby driving the valve core to move and realizing the opening and closing of the valve.

[0043] Connecting components: Used to connect the electric valve 50 to the bottom of the storage box 40 to ensure firm installation and good sealing.

[0044] For example, in practical applications, after the electric actuator receives the signal from the pressure sensor, the motor starts, drives the valve stem to rotate, and makes the valve core move, thereby opening or closing the valve channel to realize the discharge control of the material in the storage box 40.

[0045] The pressure sensor of the present application can also use some other sensors. For example, a load cell, which is usually composed of an elastomer, a strain gauge, and a measuring circuit. When a material exerts pressure on the elastomer, the elastomer deforms. The strain gauge attached to the elastomer then undergoes a change in resistance, and the measuring circuit converts the resistance change into an electrical signal output, thereby measuring the weight of the material.

[0046] Or a tension sensor, which generally includes an elastic element, a strain gauge, and a housing 705. Principle: Connect the storage tank 40 to the tension sensor through a rope or a chain. The weight of the material will generate a tension on the rope or the chain, and the tension acts on the elastic element to cause it to deform. The strain gauge detects the deformation amount and converts it into an electrical signal to measure the weight of the material.

[0047] For the improved tension sensor structure of the present application, it includes: a high-strength rope: used to connect the storage tank 40 and the tension sensor, with good tensile properties. A tension sensing element: adopting a high-precision strain gauge or a piezoresistive sensor, which can accurately sense the change in tension. A signal processing module: amplifying, filtering, and digitizing the electrical signal output by the sensing element. A mounting bracket: used to fix the tension sensor at a suitable position on the main cabinet 30.

[0048] At a suitable position inside the main cabinet 30, fix the tension sensor through the mounting bracket. Connect one end of the high-strength rope to the bottom of the storage tank 40, and the other end to the tension sensing element of the tension sensor. When the material in the storage tank 40 gradually increases and the weight of the storage tank 40 increases, a tension is applied to the tension sensing element through the rope. The tension sensing element converts the change in tension into an electrical signal and transmits it to the signal processing module. After processing the electrical signal, the signal processing module transmits it to the control system. The control system pre-sets the range of tension values corresponding to different weights of the storage tank 40. When the tension value detected by the tension sensor reaches the preset range, the control system controls the electric valve 50 to open to achieve the discharge of the material. If it is set to open the electric valve 50 when the weight of the material in the storage tank 40 reaches a certain value, when the tension value detected by the tension sensor corresponds to this weight value, the control system will issue an instruction to open the electric valve 50 to ensure accurate control of the discharge of the material.

[0049] In some embodiments, it further includes a leveling mechanism 70, which is arranged in the storage tank 40 and is used to move back and forth at the bottom of the storage tank 40.

[0050] The leveling mechanism 70 includes a driving motor 701, a belt 702, a connecting member 703, an extension member 704, and a housing 705. The housing 705 is connected to one side of the bottom of the storage box 40. The driving motor 701 and the belt 702 are both arranged inside the housing 705. The driving motor 701 is drivingly connected to the belt 702. The belt 702 extends horizontally along the side of the storage box 40. A sliding hole is provided on one side of the housing 705. One end of the connecting member 703 is connected to the belt 702, and the opposite end is slidably connected to the sliding hole. The extension member 704 is connected to the connecting member 703 and extends from one side of the storage box 40 to the opposite side.

[0051] By driving the belt 702 to move through the driving motor 701, the connecting member 703 drives the extension member 704 to move. The extension member 704 sweeps back and forth at a position close to the bottom of the storage box 40, so that the materials piled up in the storage box 40 are leveled.

[0052] The top surface of the housing 705 is an inclined surface, and the overall structure of the housing 705 is a hollow trapezoidal structure. The inclined surface structure is provided so that materials will not accumulate on the housing 705. The housing 705 shown in the drawings is the housing 705 after removing the top wall, and the actual housing 705 has a top wall.

[0053] The connecting member 703 includes a connecting rod 706 and an L-shaped sliding plate 707. One end of the connecting rod 706 is connected to the belt 702, and the opposite end is connected to the sliding plate 707. A slideway 708 with an L-shaped cross-section extending along the sliding hole direction is provided in the sliding hole. The sliding plate 707 is arranged inside the slideway 708, and the two are slidably connected. The extension member 704 is connected to the sliding plate 707. The L-shaped structures of the slideway 708 and the sliding plate 707 both extend horizontally and bend upward.

[0054] The L-shaped structures of the slideway 708 and the sliding plate 707 both extend horizontally and bend upward, so that when materials accumulate, the materials will not enter the interior of the housing 705 and only remain at the opening position of the sliding hole or the slideway 708, reducing its residual influence on the materials.

[0055] The sliding plate 707 is narrowed at the end of the slideway 708 connected to the storage box 40, so that both sides of this end of the sliding plate 707 are inclined surfaces. Such a setting enables the sliding plate 707 to clean out the materials when it slides.

[0056] A roller 709 is sleeved outside the extension member 704. The vibrating screen mechanism 20 includes a vibrating screen mesh 201, a vibrating motor, an elastic member, and a mounting rail. The mounting rail is connected to the inner wall of the storage box 40. The vibrating screen mesh 201 is connected to the elastic member, and the elastic member is connected to the mounting rail.

[0057] In some embodiments, a top hanging member 301 is further included. The top hanging member 301 includes a first hanging portion and a second hanging portion. The first hanging portion and the second hanging portion are connected at a predetermined angle. The second hanging portion is connected to the mounting rail. The first hanging portion is disposed obliquely, and the second hanging portion contracts inwardly.

[0058] In some embodiments, a protective baffle 302 is further included, which is disposed on both inner sides of the storage box 40. The mounting rail is located in the gap between the protective baffle 302 and the storage box 40.
