[0030] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] In the following embodiments and drawings, reference is made to Figure 1 The coordinate system is such that the direction indicated by the arrow of the X-axis is right, the direction indicated by the arrow of the Y-axis is forward, and the direction indicated by the arrow of the Z-axis is upward.

[0033] Among them, it is understandable that Figure 1 The feeding door 110 is in a transparent state.

[0034] Example 1:

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a dust-free feeding and metering station 10, including: a feeding bin 100, a bin body 200, a weighing module 210, a soft connecting ring 300 and a frame 400; the feeding bin 100 is arranged on the frame 400, and the feeding bin 100, the soft connecting ring 300 and the bin body 200 are connected in sequence, the soft connecting ring 300 and the bin body 200 are arranged on the inner side of the frame 400, and the weighing module 210 is arranged on the frame 400 and is arranged against the outer periphery of the supporting bin body 200 to measure the mass of the material in the bin body 200.

[0036] Specifically, the feeding bin 100 includes a feeding end and a material guide end. The feeding end may have, but is not limited to, a right-angled trapezoidal cross-sectional shape, and the width of the upper end of the feeding end is smaller than the width of the lower end. The material guide end may have, but is not limited to, a square ring shape, and the diameter of the upper end of the material guide end is larger than the diameter of the lower end. The front side of the feeding bin 100 has a feeding port, and the feeding end is welded to the upper end of the frame 400. The flexible connecting ring 300 is made of a soft material such as rubber, and the shape of the flexible connecting ring 300 may have, but is not limited to, a circular ring shape. The upper end of the flexible connecting ring 300 is connected to the material guide end, and the lower end is connected to the upper end of the bin body 200. The bin body 200 is configured in a funnel shape, with the upper end for receiving material and the lower end having a discharge port for discharging material, and the discharge port remains closed during weighing. The weighing module 210 is installed outside the silo 200 and is used to weigh the mass of the material. The weighing module 210 supports the outer periphery of the silo 200, so that the silo 200 is supported only by the weighing module 210. This allows the mass of the material inside the silo 200 to be fully measured. That is, the mass obtained by weighing the weighing module 210 minus the mass of the silo 200 itself can be obtained. The feeding silo 100, the flexible connecting ring 300, and the silo 200 can be connected by welding, and the joints between the feeding silo 100, the flexible connecting ring 300, and the silo 200 are equipped with sealing gaskets to ensure internal sealing.

[0037] It is worth noting that when the material is put into the feeding bin 100, the material will flow from the feeding bin 100 into the soft connecting ring 300 and reach the bin body 200, so that the material can be weighed by the weighing module 210 on the bin body 200. Compared with the existing feeding station, the present application supports the feeding bin 100 and the weighing module 210 through the frame 400, and the feeding bin 100 and the bin body 200 are connected by the soft connecting ring 300. In this way, the bin body 200 can be supported only on the weighing module 210, making the weighing of the weighing module 210 more accurate and high in weighing precision.

[0038] In order to make the weighing results more accurate, Figure 1 and Figure 2 As shown, in some embodiments, the number of the weighing modules 210 is set to at least two, and the at least two weighing modules 210 are evenly distributed on the outer peripheral side of the warehouse body 200.

[0039] Specifically, the number of weighing modules 210 is optional but not limited to three. The three weighing modules 210 are evenly spaced and mounted on the frame 400, located in the same mounting plane, and respectively abut the same horizontal surface of the outer peripheral side of the silo 200, thereby better supporting the silo 200 while weighing the silo 200. Each weighing module 210 is electrically connected to a control system, which calculates and averages the measurement values ​​of each weighing module 210 to derive the most accurate data. The method for each weighing module 210 to cooperate with the control system to derive the most accurate data is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0040] It is understood that the weighing module 210 can also be configured as other structures, which are not limited here, and only needs to ensure that it can abut against the outer periphery of the support silo 200 and accurately measure the mass of the material in the silo 200. For example, the weighing module 210 can be configured as an annular body, and an electronic module for measuring mass can be included therein.

[0041] Example 2

[0042] This embodiment is a further implementation of embodiment 1. Figure 1 and Figure 2 As shown, in this embodiment, the dust-free feeding and metering station 10 further includes a feeding door 110 , which is configured to movably seal the feeding bin 100 .

[0043] Specifically, the feeding door 110 is connected to the feeding end by hinges and bolts. The feeding door 110 is used to close the feeding port, so as to prevent the material from floating out of the feeding bin 100 after the material is put into the feeding bin 100, and ensure that the material falls into the feeding bin 100 relatively intact.

[0044] To further prevent the material from floating out, Figure 1 As shown, in some embodiments, a seal 111 is provided between the feeding bin 100 and the feeding door 110 .

[0045] Specifically, the sealing member 111 may be, but is not limited to, a sealing strip. A sealing seat is welded to the feeding bin 100 near the feeding port, and the sealing strip is embedded in the sealing seat. The sealing strip seals the feeding bin 100 and the feeding door 110 after the feeding door 110 is closed, thereby preventing material from leaking out of the gap between the feeding bin 100 and the feeding door 110.

[0046] In order to avoid the dust of the material affecting the operator's feeding, such as Figure 1 and Figure 2 As shown, in some embodiments, the feeding bin 100 is provided with a dust collecting assembly 500 for absorbing and fixing dust inside the feeding bin 100 .

[0047] In this way, the dust collection component 500 is turned on before feeding. When the feeding door 110 is opened for feeding, the dust collection component 500 can absorb the dust generated during the feeding process, thereby effectively preventing the generated dust from affecting the operator's feeding.

[0048] In order to facilitate the dust-free feeding and metering station 10 to perform dust collection, Figure 2 As shown, in some embodiments, the dust collection assembly 500 includes a fan 510 and a filter element 520. The filter element 520 is installed in the feeding bin 100. The fan 510 is connected to the feeding bin 100, and the fan 510 is communicated with the filter element 520 so that the dust in the feeding bin 100 is adsorbed on the filter element 520 through the negative pressure generated by the fan 510.

[0049] Specifically, the upper end of the feeding end is open, and the upper end of the feeding end is connected to a mounting plate with perforations, and the mounting plate is connected to a mounting seat with perforations by bolts. The fan 510 is bolted to the mounting seat to seal the upper end of the feeding end, that is, the mounting plate is a plate body with perforations in the middle, and the mounting seat can be set to a circular tube shape with perforations inside. The air outlet of the fan 510 and the interior of the feeding bin 100 are connected through two perforations connected up and down, so that the fan can generate suction to the interior of the feeding bin 100. A plate body is provided in the feeding bin 100, and the plate body is spaced apart from the mounting plate. The plate body is provided with an air port corresponding to the filter element 520. The filter element 520 is installed in the cavity of the feeding bin 100 through the plate body, and the fan 510 and the filter element 520 are connected through the corresponding air port, so that the fan 510 can generate suction at the filter element 520. During the feeding process, the fan 510 operates, creating a negative pressure in the feeding area. At this time, the fan 510 draws air and carries dust through the filter element 520. The dust is adsorbed on the filter element 520, and the air is discharged from the machine body through the fan 510, thereby achieving the effect of adsorbing dust.

[0050] In order to quickly absorb dust, Figure 1 and Figure 2 As shown, in some embodiments, the number of filter elements 520 is set to at least two.

[0051] Specifically, the number of filter elements 520 is optional but not limited to four. By setting multiple filter elements 520, multiple filter elements 520 can work simultaneously or separately. When working simultaneously, dust can be quickly absorbed.

[0052] Example 3

[0053] This embodiment is a further implementation of embodiment 1 or 2. Figure 2 As shown, in this embodiment, the feeding bin 100 is provided with a back-blowing component 600 for blowing dust on the filter element 520 into the bin body 200 .

[0054] In this way, by providing the backflush assembly 600 , the dust can be blown into the bin body 200 for recycling, while also extending the service life of the filter element 520 .

[0055] In order to extend the life of filter element 520, Figure 2 As shown, in some embodiments, the back-blowing assembly 600 includes an air tank 610, a fluid control valve 620 and a back-blowing nozzle 630. The fluid control valve 620 is connected to the air tank 610. One end of the back-blowing nozzle 630 is connected to the fluid control valve 620, and the other end is embedded in the feeding bin 100 and connected to the filter element 520.

[0056] Specifically, a positioning hole is opened on the feeding bin 100, and the air storage tank 610 is installed with the chuck joint of the fluid control valve 620 through a clamp and a connecting joint. The fluid control valve 620 is connected to the rear end of the back-blowing nozzle 630 by a threaded connection. The front end of the back-blowing nozzle 630 is arranged in the feeding bin 100 through the positioning hole and is arranged between the fan 510 and the filter element 520. A branch pipe is provided on the front end of the back-blowing nozzle 630, and the air outlet on each branch pipe is arranged facing the center of a filter element 520 so as to blow air from the center of the filter element 520; the four filter elements 520 are divided into two groups, with two filter elements 520 in each group, and the two groups of filter elements 520 are back-blown respectively through the back-blowing nozzle 630. Thus, during the feeding process, the fluid control valve 620 uses the gas in the gas storage tank 610 to intermittently operate the two sets of filter elements 520. The two sets of filter elements 520 operate asynchronously: while one set is blowing away dust, the other is responsible for absorbing dust. This ensures dust absorption while extending the service life of the filter elements 520. It is understood that the specific layout of each set of filter elements 520 will be based on actual production needs and is not limited here. It is only necessary to ensure that multiple filter elements 520 can achieve the goal of one set blowing away dust while the other is responsible for absorbing dust.

[0057] In order to increase the practicality of the dust-free feeding and metering station 10, as Figure 2 As shown, in some embodiments, the backflush assembly 600 further includes a manual ball valve 640 for opening or closing the gas storage tank 610 , and the manual ball valve 640 is connected to the gas storage tank 610 .

[0058] Specifically, a manual ball valve 640 is installed at the lower end of the gas tank 610. After a long period of operation, the gas tank 610 may contain moisture. In this case, the manual ball valve 640 can be opened to drain the moisture through the valve. It is understood that the manual ball valve 640 is normally closed.

[0059] Working principle: Before feeding, open the feeding door 110 and start the fan 510 to form a negative pressure in the feeding area. At this time, the dust generated during the feeding process will be adsorbed on the filter element 520. After the material enters the silo, the weighing module 210 measures and weighs it to accurately measure the input mass. During the feeding process, the fluid control valve 620 will call the gas in the gas tank 610 to work intermittently on the two groups of filter elements 520. Each group of filter elements 520 works asynchronously. When one group is backflushing, the other group is responsible for adsorbing dust. In addition, the gas tank 610 is also equipped with a manual ball valve 640, which discharges the moisture contained in the gas tank 610 after a long period of work. After the feeding is completed, close the feeding door 110, squeeze the sealing strip and tighten the screws to form a seal. At the same time, the air valve of the fan 510 is closed, and the interior of the entire machine is sealed.
