For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] The following combines Figure 1 to describe the detailed implementation manners of the quantitative feeding device of the present utility model.

[0023] The utility model provides a quantitative feeding device, comprising: a base 10, arranged at the bottom of the device; a vacuum conveying mechanism, arranged on the base 10, including a cylinder body 21 and a vacuum pump 22, one side of the cylinder body 21 is communicated with a material supply device, the other side is communicated with a conveying pipeline 23, and the vacuum pump 22 is installed on the cylinder body 21; an aluminum dish placing rack 30, used for carrying materials, and the opening end of the conveying pipeline 23 faces the aluminum dish placing rack 30; when the vacuum pump 22 operates, a negative pressure environment can be generated in the cylinder body 21, and the materials can be conveyed to the aluminum dish placing rack 30 through the conveying pipeline 23. This device is designed to replace the traditional manual weighing method, for example, it is applicable to the accurate weighing of materials such as sea sand reagents in laboratory and production environments.

[0024] Among them, the base 10 is the basic structure of the whole device, ensuring the stable connection and support between each component. The cylinder body 21 of the vacuum conveying mechanism serves as a negative pressure chamber, one end of which is connected to the material supply device, and the other end is connected to the aluminum dish placing rack 30 through the conveying pipeline 23. When the vacuum pump 22 is started, a negative pressure environment is formed in the cylinder body 21, so that the materials are sucked into the cylinder body 21 from the supply end and conveyed to the designated position - the aluminum dish placing rack 30 through the conveying pipeline 23. The aluminum dish placing rack 30 is a mechanism for receiving materials, which can be arranged below the outlet of the conveying pipeline 23 to ensure that the materials can accurately fall into the aluminum dish. In order to achieve accurate material conveying volume, the device can be equipped with a control system to accurately control the operation time of the vacuum pump 22. Through preset programs or parameter settings, the conveying time length of the materials can be controlled, so as to achieve the purpose of quantitative conveying. For example, for sea sand reagents of a specific weight, the operation time of the vacuum pump 22 required to convey this weight of materials can be determined through experiments, and then this time value is set into the control system to ensure consistent results for each conveying.

[0025] During use, first, place the materials to be weighed into the material supply device. Start the vacuum pump 22 to generate negative pressure in the cylinder body 21, and the materials are sucked into the cylinder body 21. The materials are conveyed to the upper part of the aluminum dish placing rack 30 through the conveying pipeline 23. By adjusting the working time of the vacuum pump 22, accurate material conveying volume is achieved. When the predetermined conveying time is reached, the vacuum pump 22 automatically shuts down, completing a material conveying process. The materials fall into the aluminum dish for subsequent experimental procedures. Through the solution of the utility model, not only the efficiency and accuracy of the weighing process are improved, but also the potential errors brought by manual operation are reduced, and at the same time, the labor intensity of the operators is alleviated. In addition, this automated solution can adapt to different scales of production requirements, such as large-scale production and application scenarios that require frequent repeated weighing.

[0026] According to a quantitative feeding device provided by the present utility model, a timer is provided on the power supply line of the vacuum pump 22; the timer starts timing with the start of the vacuum pump 22 and stops the operation of the vacuum pump 22 after reaching the set time. Specifically, according to the required amount of sea sand, a suitable working time can be preset through the timer. This time can be determined through experiments or empirical data to ensure that a predetermined amount of materials can be transported within the set time. When the vacuum pump 22 starts, a negative pressure is generated in the cylinder body 21, sucking the materials from the supply end into the cylinder body 21 and transporting them to the aluminum dish placement rack 30 through the conveying pipeline 23. During the whole process, the timer will keep timing. Once the preset time is reached, the timer will trigger the automatic stop mechanism of the vacuum pump 22, that is, cut off the power supply of the vacuum pump 22 to make it stop running. At this time, the material transportation process will also end immediately.

[0027] In a preferred embodiment, the circuit of the vacuum pump 22 may include a timer, a power supply, a relay, etc. During use, the power supply provides the voltage required by the system, such as 220V alternating current. The operator can set the time of the timer according to the amount of materials to be transported. After the relay is turned on, the vacuum pump 22 starts to work, generating a negative pressure to send the materials from the cylinder body 21 to the aluminum dish placement rack 30 through the conveying pipeline 23. When the timer reaches the set time, a signal is sent to the relay, and the relay is turned off, and the vacuum pump 22 stops working. Among them, the timer preferably has an adjustable time setting function to meet the requirements of different material amounts.

[0028] According to a quantitative feeding device provided by the present utility model, the aluminum dish placement rack 30 is provided with a receiving groove 31 and a weighing device 32; the open direction of the receiving groove 31 faces upward for holding materials; the weighing device 32 is located below the receiving groove 31 for weighing the weight change of the receiving groove 31. Among them, the weighing device 32 can use a resistance strain gauge sensor or other types of sensors (such as piezoelectric, capacitive, etc.) to measure the weight change. The receiving groove 31 with the open direction facing upward is conducive to reliably holding the materials.

[0029] According to a quantitative feeding device provided by the present utility model, a sliding track 33 is provided between the aluminum dish placement rack 30 and the base 10; the aluminum dish placement rack 30 can move along the sliding track 33 to approach or move away from the open end of the conveying pipeline 23 in the horizontal direction. The aluminum dish placement rack 30 can conveniently adjust its position, facilitating the operator to load and unload materials according to needs, improving the convenience and flexibility of operation. When the aluminum dish placement rack 30 approaches the open end of the conveying pipeline 23, the materials can fall more accurately into the aluminum dish, reducing the possibility of material scattering, thereby improving the accuracy of material transportation. When the aluminum dish placement rack 30 moves away from the open end of the conveying pipeline 23, it can avoid collision or interference with other equipment in subsequent experimental processes, ensuring the safe operation of the experimental equipment.

[0030] Preferably, the sliding track 33 may be composed of a track, pulleys, a control system, etc.; the pulley is pneumatically driven to enable the aluminum dish placement rack 30 to automatically slide on the track. The track is fixed on the base 10 to provide a moving path for the aluminum dish placement rack 30. The pulley is installed under the aluminum dish placement rack 30 and contacts the track, and is used to support the aluminum dish placement rack 30 and ensure its smooth movement. The pneumatic drive system may include components such as a cylinder, a pneumatic valve, a compressed air source, etc., and is used to drive the aluminum dish placement rack 30 to move on the track.

[0031] According to a quantitative feeding device provided by the present invention, a linear driver is arranged on the sliding track 33, and the linear driver is used to drive the aluminum dish placement rack 30 to move along the sliding track 33. Through the driving action of the linear driver, the aluminum dish placement rack 30 can automatically achieve precise and stable horizontal movement on the sliding track 33. For example, the linear driver may include a rotary motor and a transmission mechanism, and is used in cooperation with the above-mentioned sliding track 33. Among them, the rotary motor provides a power source, usually a stepper motor or a servo motor; the transmission mechanism may adopt a lead screw nut mechanism or a rack and pinion mechanism, etc., to ensure smooth and precise linear movement; the sliding track 33 provides support and a smooth moving path for the aluminum dish placement rack 30.

[0032] According to a quantitative feeding device provided by the present invention, position sensors 34 are arranged on at least one side of the sliding track 33 to detect the moving position of the aluminum dish placement rack 30 on the sliding track 33, so as to ensure that the aluminum dish placement rack 30 can accurately move to a predetermined position. Through the feedback information of the position sensors 34, the control system or the operator can accurately control the working state of the device. The position sensors 34 preferably are based on the principle of electromagnetic induction and are composed of an induction coil, an electronic circuit and an output device, etc., so as to be suitable for the detection of metal objects, such as the aluminum dish placement rack 30. The position sensors 34 can be used to monitor the movement track of the aluminum dish placement rack 30 to ensure that it moves along a preset path. When the aluminum dish placement rack 30 reaches the predetermined position, the position sensors 34 will send out signals, and the control system will perform the next operation according to these signals, such as stopping moving, starting the blanking process, etc.

[0033] Furthermore, according to a quantitative feeding device provided by the present utility model, the number of position sensors 34 is two, and the positions of the two position sensors 34 respectively correspond to the feeding position and the completion position of the aluminum dish placement rack 30 on the sliding track 33; at the feeding position, the aluminum dish placement rack 30 is directly below the opening end of the conveying pipeline 23; at the completion position, the aluminum dish placement rack 30 is at the farthest end of the sliding track 33 relative to the vacuum conveying mechanism. The aluminum dish placement rack 30 moves between the feeding position and the completion position to ensure that the material can be smoothly fed by vacuum and the next experimental process can be carried out at the completion position. Among them, the feeding position refers to the position where the aluminum dish placement rack 30 is directly below the opening end of the conveying pipeline 23. At this position, the aluminum dish is exactly in the state of receiving the material. The completion position refers to the position where the aluminum dish placement rack 30 is at the farthest end of the sliding track 33 relative to the vacuum conveying mechanism. At this position, the aluminum dish placement rack 30 has completed loading and is ready for the next experimental process. When the aluminum dish placement rack 30 reaches the feeding position, the first position sensor 34 will detect and send a signal to the control system. After receiving the signal, the control system can start the material conveying process to make the material accurately fall into the aluminum dish. Once the aluminum dish placement rack 30 leaves the feeding position, the control system will immediately stop the vacuum conveying of the material and prevent the vacuum conveying mechanism from being accidentally started.

[0034] According to a quantitative feeding device provided by the present utility model, the base 10 is provided with a vertical support, and the vertical support includes a vertical plate 11 perpendicular to the base 10; the vertical plate 11 is provided with a support hole adapted to the conveying pipeline 23. The vertical support is used to support the conveying pipeline 23 to ensure that the conveying pipeline 23 is stably connected to the device. Through the support hole on the vertical plate 11, the position of the conveying pipeline 23 can be ensured, avoiding affecting the accuracy of material conveying due to pipeline shaking.

[0035] According to a quantitative feeding device provided by the present utility model, the vertical support includes a first mounting plate 12 perpendicular to the vertical plate 11; the first mounting plate 12 is mounted on the vertical plate 11 and is provided with a first mounting hole position adapted to the vacuum pump 22 for stably mounting the vacuum pump 22. Among them, through the first mounting plate 12, the vacuum pump 22 can be stably mounted on the vertical support, ensuring the reliability and stability of the vacuum pump 22 during operation, thereby guaranteeing the accuracy of material conveying.

[0036] According to a quantitative feeding device provided by the present utility model, the vertical support includes a second mounting plate 13 perpendicular to the vertical plate 11; the second mounting plate 13 is mounted on the vertical plate 11 and is located on the opposite side of the first mounting plate 12, and the second mounting plate 13 is provided with a second mounting hole position adapted to the opening end of the conveying pipeline 23. Through the fixing effect of the second mounting plate 13 on the conveying pipeline 23, the second mounting hole position fixes the position of the opening end of the conveying pipeline 23, thereby ensuring the accuracy and stability of material conveying.

[0037] According to a preferred embodiment of the present application, the quantitative feeding device is applied to the weighing process of sea sand detection. Specifically, the working time of the vacuum pump 22 is preset based on the required amount of sea sand. During operation, the suction nozzle starts to collect granular sea sand materials, continuously extracts and conveys the materials to a designated position within the preset time. Once the set time is reached, the vacuum pump 22 automatically stops working, thus interrupting the material conveyance. This method can save time, improve weighing efficiency, and achieve automated operation. In addition, the device can also be integrated with other automated systems to further improve the efficiency of the entire production line.
