[0037] Referring to Figure 1 and Figure 4 A powder filling and feeding device, which comprises a base 100, a bin mechanism 200 and a control mechanism 300, the base 100 is provided with at least two discharge pipes 110, the bin mechanism 200 is fixedly connected to the base 100 and is provided with at least two material cavities 201 for filling powder materials, a feeding channel 202 is correspondingly arranged at the lower side of each material cavity 201 of the bin mechanism 200, the feeding channel 202 is communicated with the corresponding material cavity 201, the control mechanism 300 is connected to the base 100 and is arranged between the bin mechanism 200 and the discharge pipe 110, and the control mechanism 300 can quantitatively convey the powder material in the feeding channel 202 into the discharge pipe 110.

[0038] It can be understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the hopper mechanism 200 includes a material box 210 and a feeding assembly 220 arranged at the lower side of the material box 210, the material box 210 has an inner cavity, and two first partitions 211 are arranged in the inner cavity, which divides the inner cavity of the material box 210 into three material cavities 201. Correspondingly, the feeding assembly 220 is provided with three feeding channels 202, the upper part of the feeding channel 202 is the feeding end, and the lower part is the discharging end. Each feeding channel 202 has one feeding end and two discharging ends. The feeding end of the feeding channel 202 communicates with the material cavity 201, and the discharging end of the feeding channel 202 is connected with the control mechanism 300. Six discharging pipes 110 are arranged on the machine base 100 corresponding to the discharging end of the feeding channel 202, each discharging pipe 110 is arranged below the discharging end of the corresponding feeding channel 202, and the control mechanism 300 is connected to the machine base 100 and arranged between the discharging end of the feeding channel 202 and the discharging pipe 110. In use, different mesh powders can be filled in different material cavities 201, and the powders in different material cavities 201 enter the corresponding feeding channel 202. The control mechanism 300 is used to quantitatively deliver the powders in different feeding channels 202 to the discharging pipe 110, so as to realize the quantitative output of different mesh powders, which can better adapt to the continuous production requirements of different mesh powders filled in the heat pipe, and is beneficial to improve the production efficiency and reduce the production equipment cost, and is convenient for production application.

[0039] In actual application, the material cavity 201 can also be provided as two, four or more, and the feeding channel 202 can also adopt a structure of one feeding end and one discharging end. In addition to the above structure, the hopper mechanism 200 can also include a plurality of material boxes 210, each material box 210 is provided with one or more material cavities 201, and the feeding assembly 220 can be connected by a plurality of pipes. The specific structure of the control mechanism 300 will not be described here in detail, and will be described in detail below.

[0040] In some embodiments, the control mechanism 300 includes a control seat 310 and a first driver 320. The control seat 310 is slidingly connected to the machine base 100, and a plurality of quantitative cavities 301 are arranged on the control seat 310. The plurality of quantitative cavities 301 are arranged one by one corresponding to the discharging ends of the plurality of feeding channels 202. The first driver 320 is drivingly connected with the control seat 310, and is used to drive the control seat 310 to move relative to the machine base 100, so as to enable the quantitative cavity 301 to move to be in abutting communication or misaligned disconnection with the corresponding feeding channel 202. When the quantitative cavity 301 is in abutting communication with the feeding channel 202, the powder in the feeding channel 202 can enter the quantitative cavity 301, and the control mechanism 300 can enable the discharging end of the quantitative cavity 301 to communicate with or disconnect from the feeding end of the discharging pipe 110.

[0041] It can be understood that, as Figure 2 andFigure 3 As shown, the material control seat 310 is slidingly connected to the machine base 100 in the front-rear direction, and the three feeding channels 202 on the feeding assembly 220 have a total of six discharge ends, which are respectively connected to the six discharge ends of the material control seat 310. Figure 4 、 Figure 6 、 Figure 7 and Figure 8 Therefore, the material control seat 310 is provided with six dosing cavities 301, each of which corresponds to a discharge end of the feeding channel 202. The upper side of the dosing cavity 301 is the feeding end, and the lower side is the discharge end and corresponds to the feeding end of the discharge pipe 110. In use, the material control mechanism 300 closes the discharge end of the dosing cavity 301, the first drive 320 drives the material control seat 310 to move, and the feeding end of the dosing cavity 301 is moved to be connected to the discharge end of the corresponding feeding channel 202. At this time, since the discharge end of the dosing cavity 301 is closed and disconnected from the feeding end of the discharge pipe 110, the powder material in the feeding channel 202 enters and fills the dosing cavity 301. Subsequently, the first drive 320 drives the material control seat 310 to reset and move, so that the feeding end of the dosing cavity 301 is dislocated and disconnected from the discharge end of the corresponding feeding channel 202. At this time, the material control seat 310 closes the discharge end of the feeding channel 202, the material control mechanism 300 opens the discharge end of the dosing cavity 301, and the discharge end of the dosing cavity 301 is connected to the feeding end of the discharge pipe 110, so that the powder material in the dosing cavity 301 enters the discharge pipe 110, thereby realizing the quantitative output of the powder material. The structure is simple, the volume of the output powder material can be well controlled by the dosing cavity 301, and it is convenient to use.

[0042] In actual application, the first drive 320 can be a pneumatic cylinder, a linear motor or an electric push rod, etc. In addition to the above structure, the quantitative output of the powder material can also be realized in the form of flow control, for example, a switch valve is arranged at the discharge end of the feeding channel 202. When the switch valve controls the discharge end of the feeding channel 202 to be opened, the output amount of the powder material is calculated by using a flowmeter or an opening and closing time control method, thereby realizing the quantitative output. Alternatively, by weighing, when the powder material falling into the dosing cavity 301 reaches a preset weight, the discharge end of the feeding channel 202 is closed and the discharge end of the dosing cavity 301 is opened, so that the powder material of the preset weight is input into the discharge pipe 110. The specific number and distribution of the dosing cavity 301 can be set according to actual use needs.

[0043] In some embodiments, the material control mechanism 300 further comprises an opening and closing member 330 movably arranged on the material control seat 310 and provided with the first through hole 302, and a second driver 340 drivingly connected with the opening and closing member 330 for driving the opening and closing member 330 to move relative to the material control seat 310, so as to enable the first through hole 302 to move to be in abutting communication or dislocation with the discharge end of the dosing chamber 301. When the first through hole 302 is in abutting communication with the discharge end of the dosing chamber 301, the discharge end of the dosing chamber 301 can be communicated with the inlet end of the discharge pipe 110 through the first through hole 302.

[0044] It can be understood that, as shown in Figure 4 、 Figure 6 、 Figure 7 and Figure 8 , the opening and closing member 330 is movably arranged on the lower side of the material control seat 310, and is provided with three first through holes 302 corresponding to the three material chambers 201 respectively. Each opening and closing member 330 is provided with a first through hole 302 corresponding to the dosing chamber 301. In use, the second driver 340 drives the opening and closing member 330 to move, so as to enable the first through hole 302 to move to be in dislocation with the discharge end of the dosing chamber 301. At this time, the discharge end of the dosing chamber 301 is in a closed state, and the discharge end of the dosing chamber 301 is disconnected from the inlet end of the discharge pipe 110. When the dosing chamber 301 is filled with powder material, the second driver 340 drives the opening and closing member 330 to reset and move, so as to enable the first through hole 302 to move to be in abutting communication with the discharge end of the dosing chamber 301. At this time, the discharge end of the dosing chamber 301 is in an open state, and the discharge end of the dosing chamber 301 is communicated with the inlet end of the discharge pipe 110 through the first through hole 302, so as to enable the powder material in the dosing chamber 301 to enter the discharge pipe 110. The above structure is simple, can adapt to the control condition that multiple dosing chambers 301 are opened or closed together, and is convenient to use.

[0045] In practical applications, in addition to the above structure, a switching valve can be installed at the discharge end of the metering chamber 301 to control its opening and closing. The second driver 340 can be a cylinder, a linear motor, or an electric push rod, etc. The second driver 340 can be set as one to drive the three opening and closing elements 330 to move together, or the second driver 340 can be set as three, with each of the three second drivers 340 driving the three opening and closing elements 330 to move independently. In addition, by setting different positions of the first through holes 302 on each opening and closing element 330, the opening and closing of the discharge ends of different metering chambers 301 can be achieved by utilizing the positional differences of the first through holes 302 when the three opening and closing elements 330 move together. The sequence control is achieved by, for example, positioning the first through hole 302 on the leftmost opening / closing element 330 slightly forward compared to the first through hole 302 on the middle opening / closing element 330, and positioning the first through hole 302 on the rightmost opening / closing element 330 slightly backward compared to the first through hole 302 on the middle opening / closing element 330. In this way, when the three opening / closing elements 330 move together, the first through hole 302 on each opening / closing element 330 will connect with the corresponding metering chamber 301 when they move to different positions, thereby achieving the sequence control of the opening and closing of the discharge end of different metering chambers 301. The specific settings can be adjusted according to actual usage requirements.

[0046] In some embodiments, the lower side of the control base 310 is provided with a base plate 312, and the base plate 312 is provided with a limiting groove 304 for accommodating the opening and closing member 330. The opening and closing member 330 is disposed in the limiting groove 304, and the bottom of the limiting groove 304 is provided with a discharge port 305 corresponding to the discharge pipe 110. When the first through hole 302 is connected to the discharge end of the metering cavity 301, the first through hole 302 is connected to the corresponding discharge port 305.

[0047] Understandably, such as Figure 7 and Figure 8 As shown, the base plate 312 is fixedly connected to the lower side of the control seat 310, and the discharge port 305 on it is located below the corresponding metering cavity 301. By setting the base plate 312 and the limiting groove 304, during use, the opening and closing member 330 moves back and forth along the limiting groove 304, which can effectively limit the movement of the opening and closing member 330, and at the same time, it can support the opening and closing member 330, so that it can fit well against the control seat 310. When the first through hole 302 is completely misaligned with the metering cavity 301, the opening and closing member 330 can effectively close the discharge end of the metering cavity 301, which is convenient for use. In actual applications, the base plate 312 can be set according to the actual use needs.

[0048] In some embodiments, the machine base 100 is provided with a feeding hopper 120 corresponding to each discharge pipe 110 at the upper end thereof, the upper side of the feeding hopper 120 is open, the control seat 310 is located above the feeding hopper 120, when the first through hole 302 is connected in communication with the discharge end of the quantitative cavity 301, the powder material in the quantitative cavity 301 can fall into the feeding hopper 120 through the first through hole 302.

[0049] It can be understood that, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the upper side of each discharge pipe 110 is provided with a feeding hopper 120, the feeding hopper 120 is located below the bottom plate 312 and has a predetermined distance from the bottom plate 312, the upper side of the feeding hopper 120 is open, when the first through hole 302 is connected in communication with the discharge end of the quantitative cavity 301, the first through hole 302 is connected in communication with the corresponding discharge port 305, the powder material in the quantitative cavity 301 falls through the first through hole 302 and the discharge port 305 into the feeding hopper 120, so as to be collected into the discharge pipe 110 through the feeding hopper 120, which has a simple structure, can avoid the trouble of connecting the first through hole 302 and the discharge pipe 110 through a pipeline, is conducive to the movement of the control seat 310 and the opening and closing member 330, and is convenient to use. In actual application, in addition to the feeding hopper 120, the first through hole 302 and the discharge pipe 110 or the discharge port 305 and the discharge pipe 110 can also be connected through a pipeline, which can be set according to actual needs.

[0050] In some embodiments, the upper side of the control seat 310 is provided with an open slot 303, the upper side of the open slot 303 is open, the quantitative cavity 301 is located below the open slot 303, the lower side of the hopper mechanism 200 extends into the open slot 303 and contacts the bottom of the open slot 303, when the quantitative cavity 301 is disconnected from the feeding channel 202, the quantitative cavity 301 is connected in communication with the open slot 303.

[0051] It can be understood that, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 8As shown, the upper side of the material control seat 310 is provided with an open recessed cavity, and a second partition plate 311 is arranged in the recessed cavity. The second partition plate 311 divides the upper side of the material control seat 310 into a plurality of open grooves 303. The lower side of the feeding assembly 220 extends into the open grooves 303 and is in contact with the bottom of the open grooves 303. In use, the material control seat 310 moves back and forth relative to the machine base 100, so that the lower part of the feeding assembly 220 moves back and forth along the open grooves 303. When the dosing cavity 301 is connected to the discharge end of the feeding channel 202, the two are connected, and the powder material enters the dosing cavity 301. When the two are completely misaligned, the dosing cavity 301 is disconnected from the feeding channel 202, and the bottom of the open groove 303 closes the discharge end of the feeding channel 202. At this time, the dosing cavity 301 is connected to the open groove 303, so that the negative pressure formed in the dosing cavity 301 can be avoided, and the powder material in the dosing cavity 301 can be easily discharged. In addition, the open groove 303 can also prevent the powder material from escaping to the outer periphery of the material control seat 310, which is convenient to use. In actual application, the specific structure of the open groove 303 can be set according to actual needs.

[0052] In some embodiments, the hopper mechanism 200 is provided with a second through hole 203 corresponding to the feeding channel 202. The feeding channel 202 is connected to the second through hole 203 and can be connected to the external atmosphere through the second through hole 203.

This is beneficial to ensure the smoothness of the powder material conveying. In actual application, the second through hole 203 can be set according to actual needs.

[0054] In some embodiments, the feeding channel 202 includes a first channel section 202a, a second channel section 202b and a third channel section 202c. The first channel section 202a extends in the vertical direction and is connected to the material cavity 201. The third channel section 202c is used to be connected to the dosing cavity 301. The second channel section 202b is arranged obliquely relative to the axis direction of the first channel section 202a, and the two ends of the second channel section 202b are connected to the first channel section 202a and the third channel section 202c, respectively. The two ends of the second through hole 203 have a predetermined height difference. The lower end of the second through hole 203 is connected to the second channel section 202b, and the upper end of the second through hole 203 is connected to the external atmosphere.
