Description

Technical Field

[0001] The present invention relates to the technical field of heat pipe production, and particularly relates to a powder filling feeding device and a powder filling equipment. Background Art

[0002] In the existing heat pipe production technology, some heat pipes adopt the method of powder filling and sintering to form a wick structure inside to achieve heat transfer and dissipation of the heat pipe. In order to improve the performance of the heat pipe, some heat pipes adopt multi-segment powder filling distribution with different mesh numbers. For example, the heat pipe for facilitating heat transfer and dissipation disclosed in Chinese Patent CN202320405652.8 has three segments of powder filling inside, and the mesh numbers of the adjacent two segments of powder are different. Of course, there are also some heat pipes that adopt two or four segments of powder filling with different mesh numbers.

[0003] However, for this type of heat pipe with multi-segment powder filling of different mesh numbers, the existing powder filling equipment is still relatively backward. Each time the feeding device performs a powder filling operation, it can only provide a powder material of one mesh number. Therefore, during the production process, after filling one segment of powder, it is necessary to replace the powder material in the feeding device, and then fill the next segment of powder with a different mesh number. The production efficiency of this operation method is relatively low. In addition, if multiple powder filling equipment are connected in series to separately fill powders with different mesh numbers, it will significantly increase the equipment cost and occupy a large production site, which is not conducive to production applications. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a powder filling feeding device, which can be used to load powder materials with different mesh numbers by setting multiple material chambers during use, and realizes the quantitative output and feeding of powder materials with different mesh numbers in different material chambers by using a material control mechanism, and can better meet the continuous production requirements of multi-segment powder filling of different mesh numbers in heat pipes, facilitating production applications.

[0037] Referring to Figure 1 and Figure 4 , a powder filling and feeding device, which includes a machine base 100, a material bin mechanism 200 and a material control mechanism 300. At least two discharge pipes 110 are provided on the machine base 100. The material bin mechanism 200 is fixedly connected to the machine base 100 and is provided with at least two material cavities 201 for filling powder materials. A feeding channel 202 is correspondingly provided on the lower side of each material cavity 201 of the material bin mechanism 200. The feeding channel 202 is communicated with the corresponding material cavity 201. The material control mechanism 300 is connected to the machine base 100 and is arranged between the material bin mechanism 200 and the discharge pipe 110. The material 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 such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the silo mechanism 200 includes a material box 210 and a feeding component 220 disposed on 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. The two first partitions 211 divide the inner cavity of the material box 210 into three material chambers 201. Correspondingly, the feeding component 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 chamber 201, and the discharging end of the feeding channel 202 is docked with the material control mechanism 300. Six discharging pipes 110 are provided on the machine base 100 corresponding to the discharging ends of the feeding channels 202. Each discharging pipe 110 is disposed below the discharging end of the corresponding feeding channel 202. The material control mechanism 300 is connected to the machine base 100 and is disposed between the discharging end of the feeding channel 202 and the discharging pipe 110. During use, powder materials of different meshes can be loaded into different material chambers 201. The powder materials in different material chambers 201 enter the corresponding feeding channels 202. The material control mechanism 300 is used to quantitatively transport the powder materials in different feeding channels 202 to the discharging pipes 110, so as to realize the quantitative output and feeding of powder materials of different meshes, which can better meet the continuous production requirements of multi-segment powder filling of different meshes in heat pipes, is beneficial to improving production efficiency and reducing the cost of production equipment, and is convenient for production application.

[0039] In actual application, the number of material chambers 201 can also be set to two, four or more. The feeding channel 202 can also adopt a structure with one feeding end and one discharging end. In addition to the above structure, the silo mechanism 200 can also include multiple material boxes 210. Each material box 210 is correspondingly provided with one or more material chambers 201. The feeding component 220 can be formed by connecting multiple pipes. Specifically, it can be set according to actual use needs. The specific structural form of the material control mechanism 300 will not be described in detail here and will be further described below.

[0040] In some embodiments, the material control mechanism 300 includes a material control seat 310 and a first driver 320. The material control seat 310 is slidably connected to the machine base 100. A plurality of quantitative chambers 301 are provided on the material control seat 310. The plurality of quantitative chambers 301 are respectively arranged in one-to-one correspondence with the discharging ends of the plurality of feeding channels 202. The first driver 320 is drivingly connected to the material control seat 310 and is used to drive the material control seat 310 to move relative to the machine base 100 so that the quantitative chamber 301 can move to be docked and communicated with the corresponding feeding channel 202 or be misaligned and disconnected. When the quantitative chamber 301 is docked and communicated with the feeding channel 202, the powder material in the feeding channel 202 can enter the quantitative chamber 301. The material control mechanism 300 can make the discharging end of the quantitative chamber 301 communicate or disconnect with the feeding end of the discharging pipe 110.

[0041] It can be understood that, such as Figure 2 andFigure 3 As shown, the material control seat 310 is slidably connected to the machine base 100 in the front-rear direction. The three feeding channels 202 on the feeding assembly 220 have a total of six discharging ends. Refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 . Thus, six metering cavities 301 are provided on the material control seat 310, and each metering cavity 301 corresponds to one discharging end of the feeding channel 202. The upper side of the metering cavity 301 is the feeding end, and the lower side thereof is the discharging end and corresponds to the feeding end of the discharging pipe 110. During use, the material control mechanism 300 closes the discharging end of the metering cavity 301, and the first driver 320 drives the material control seat 310 to move, so that the feeding end of the metering cavity 301 moves to be docked and communicated with the discharging end of the corresponding feeding channel 202. At this time, since the discharging end of the metering cavity 301 is closed and is disconnected from the feeding end of the discharging pipe 110, the powder material in the feeding channel 202 enters and fills the metering cavity 301. Subsequently, the first driver 320 drives the material control seat 310 to reset and move, so that the feeding end of the metering cavity 301 is misaligned and disconnected from the discharging end of the corresponding feeding channel 202. At this time, the material control seat 310 closes the discharging end of the feeding channel 202, and the material control mechanism 300 opens the discharging end of the metering cavity 301. The discharging end of the metering cavity 301 is communicated with the feeding end of the discharging pipe 110, so that the powder material in the metering cavity 301 enters the discharging pipe 110, thereby realizing the quantitative output of the powder material. The structure is simple, and the volume of the output powder material can be well controlled through the metering cavity 301, which is convenient for use.

[0042] In actual application, the first driver 320 can be a 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 switching valve is provided at the discharging end of the feeding channel 202. When the switching valve controls the discharging end of the feeding channel 202 to open, the output amount of the powder material is calculated by means of a flow meter or opening and closing time control, etc., so as to realize the quantitative output. Or, by means of weighing, when the powder material falling into the metering cavity 301 reaches the preset weight, the discharging end of the feeding channel 202 is closed and the discharging end of the metering cavity 301 is opened, so that the powder material of the preset weight is input into the discharging pipe 110. The specific setting quantity and distribution of the metering cavity 301 can be set accordingly according to the actual use requirements.

[0043] In some embodiments, the material control mechanism 300 further includes an opening / closing member 330 and a second driver 340. The opening / closing member 330 is movably disposed on the material control base 310 and is provided with a first through hole 302. The second driver 340 is drivingly connected to the opening / closing member 330 and is configured to drive the opening / closing member 330 to move relative to the material control base 310, so that the first through hole 302 can be moved to be butt-connected and communicated with the discharge end of the metering chamber 301 or be misaligned and disconnected. When the first through hole 302 is butt-connected and communicated with the discharge end of the metering chamber 301, the discharge end of the metering chamber 301 can be communicated with the feed end of the discharge pipe 110 through the first through hole 302.

[0044] It can be understood that, as Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, the opening / closing member 330 is movably disposed at the lower side of the material control base 310 in the front-back direction. The opening / closing member 330 is provided with three to respectively correspond to the three material chambers 201. Each opening / closing member 330 is provided with a first through hole 302 corresponding to the metering chamber 301. During use, the second driver 340 drives the opening / closing member 330 to move, so that the first through hole 302 is moved to be misaligned and disconnected from the discharge end of the metering chamber 301. At this time, the discharge end of the metering chamber 301 is in a closed state, and the discharge end of the metering chamber 301 is disconnected from the feed end of the discharge pipe 110. When the metering chamber 301 is filled with powder material, the second driver 340 drives the opening / closing member 330 to move back to its original position, so that the first through hole 302 is moved to be butt-connected and communicated with the discharge end of the metering chamber 301. At this time, the discharge end of the metering chamber 301 is in an open state, and the discharge end of the metering chamber 301 is communicated with the feed end of the discharge pipe 110 through the first through hole 302, so that the powder material in the metering chamber 301 enters the discharge pipe 110. The above structure is simple, can adapt to the control situation of multiple metering chambers 301 being opened or closed together, and is convenient for use.

[0045] In actual application, in addition to the above structure, a switch valve can be set at the discharge end of the quantitative chamber 301 to realize its opening and closing control. 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 and drive the three opening and closing parts 330 to move together, or the second driver 340 can be set as three, and the three second drivers 340 respectively drive the three opening and closing parts 330 to move separately. In addition, by setting the position of the first through hole 302 on each opening and closing part 330 to be different, when the three opening and closing parts 330 move together, the position difference of the first through hole 302 can be used to realize the opening and closing of the discharge ends of different quantitative chambers 301 For example, the position of the first through hole 302 on the opening and closing member 330 on the far left is designed to be closer to the front than the position of the first through hole 302 on the opening and closing member 330 in the middle, while the position of the first through hole 302 on the opening and closing member 330 on the far right is designed to be closer to the back than the position of the first through hole 302 on the opening and closing member 330 in the middle. In this way, when the three opening and closing members 330 move together and move to different positions, the first through holes 302 on different opening and closing members 330 will be connected with the corresponding quantitative chambers 301, thereby realizing the opening and closing sequence control of the discharge ends of different quantitative chambers 301, which can be set accordingly according to actual use needs.

[0046] In some embodiments, a bottom plate 312 is provided on the lower side of the material control seat 310, and a limiting groove 304 is provided on the bottom plate 312 for accommodating the opening and closing component 330. The opening and closing component 330 is arranged in the limiting groove 304, and a drop-out port 305 corresponding to the discharge pipe 110 is provided at the bottom of the limiting groove 304. When the first through hole 302 is connected with the discharge end of the quantitative chamber 301, the first through hole 302 is connected with the corresponding drop-out port 305.

[0047] It is understandable that if Figure 7 and Figure 8 As shown, the bottom plate 312 is fixedly connected to the lower side of the material control seat 310, and the material drop opening 305 thereon is located below the corresponding quantitative cavity 301. By setting the bottom plate 312 and the limit groove 304, when in use, the opening and closing member 330 moves forward and backward along the limit groove 304, which can better limit the movement of the opening and closing member 330, and at the same time can play a supporting effect on the opening and closing member 330, so that it can better fit the material control seat 310. When the first through hole 302 and the quantitative cavity 301 are completely staggered, the opening and closing member 330 can be used to better close the discharge end of the quantitative cavity 301, which is convenient for use. In actual application, the bottom plate 312 can be set accordingly according to actual use needs.

[0048] In some embodiments, a feed hopper 120 is correspondingly provided at the upper end of each discharge pipe 110 of the machine base 100. The upper side of the feed hopper 120 has an open structure. The material control base 310 is located above the feed hopper 120. When the first through hole 302 is in butt joint and communication with the discharge end of the metering chamber 301, the powder material in the metering chamber 301 can fall into the feed hopper 120 through the first through hole 302.

[0049] It can be understood that as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a feed hopper 120 is provided on the upper side of each discharge pipe 110. The feed hopper 120 is located below the bottom plate 312 and has a preset distance from the bottom plate 312. The upper side of the feed hopper 120 has an open structure. When the first through hole 302 is in butt joint and communication with the discharge end of the metering chamber 301, the first through hole 302 is in butt joint and communication with the corresponding material dropping port 305. The powder material in the metering chamber 301 falls to the feed hopper 120 through the first through hole 302 and the material dropping port 305, and thus is gathered into the discharge pipe 110 through the feed hopper 120. Its structure is simple, which can avoid the trouble of connecting the first through hole 302 and the discharge pipe 110 through a pipeline, is beneficial to the movement of the material control base 310 and the opening and closing member 330, and is convenient to use. In actual application, in addition to providing the feed hopper 120, the first through hole 302 and the discharge pipe 110 or the material dropping port 305 and the discharge pipe 110 can also be connected through a pipeline, which can be specifically set according to actual use needs.

[0050] In some embodiments, an opening groove 303 is provided on the upper side of the material control base 310. The upper side of the opening groove 303 has an open structure. The metering chamber 301 is located below the opening groove 303. The lower side of the material bin mechanism 200 extends into the opening groove 303 and contacts the bottom of the opening groove 303. When the metering chamber 301 is misaligned and disconnected from the feeding channel 202, the metering chamber 301 communicates with the opening groove 303.

[0051] It can be understood that as Figure 1 , Figure 2 , Figure 4 and Figure 8As shown in the figure, an open concave cavity is provided on the upper side of the material control seat 310, and a second partition 311 is arranged in the concave cavity. By using the second partition 311, the upper side of the material control seat 310 is divided to form a plurality of open slots 303. The lower side of the feeding assembly 220 extends into the open slots 303 and contacts the bottom of the open slots 303. During 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 slots 303. When the quantitative cavity 301 is docked with the discharge end of the feeding channel 202, the two are communicated, and the powder material enters the quantitative cavity 301. When the two are completely staggered, the quantitative cavity 301 is disconnected from the feeding channel 202, and the bottom of the open slot 303 closes the discharge end of the feeding channel 202. At this time, the quantitative cavity 301 is communicated with the open slot 303, so as to avoid the formation of negative pressure in the quantitative cavity 301, resulting in difficulty in discharging the internal powder material. At the same time, the open slot 303 can also be used to prevent the powder material from escaping to the periphery of the material control seat 310, which is convenient for use. In actual application, the specific structure of the open slot 303 can be set according to actual use needs.

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

[0053] It can be understood that, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, by providing the second through hole 203, the feeding channel 202 can be communicated with the external atmospheric environment through the second through hole 203, so as to avoid the formation of negative pressure inside the feeding channel 202, resulting in difficulty in the internal powder material entering the quantitative cavity 301, which is beneficial to ensuring the smoothness of the powder material transportation. In actual application, the second through hole 203 can be set according to actual use 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 communicated with the material cavity 201. The third channel section 202c is used to be communicated with the quantitative cavity 301. The second channel section 202b is inclined relative to the axis direction of the first channel section 202a, and both ends of the second channel section 202b are communicated with the first channel section 202a and the third channel section 202c respectively. Both ends of the second through hole 203 have a preset height difference. The lower end of the second through hole 203 is communicated with the second channel section 202b, and the upper end of the second through hole 203 is communicated with the external atmospheric environment.

[0055] It can be understood that, as Figure 1 , Figure 2 , Figure 4 andFigure 5 As shown, the first channel section 202a is located at the upper part of the feeding channel 202, which is connected to the material cavity 201 and belongs to the feeding channel part of the feeding channel 202. The third channel section 202c is located at the lower part of the feeding channel 202, which is arranged corresponding to the metering cavity 301 and belongs to the discharging channel part of the feeding channel 202. The second channel section 202b is located between the first channel section 202a and the third channel section 202c and connects the two. The axes of the first channel section 202a and the third channel section 202c are both parallel to the vertical direction to facilitate the entry and discharge of powder materials. The second channel section 202b is inclined relative to the axis direction of the first channel section 202a, so that a bent channel structure is formed among the first channel section 202a, the second channel section 202b and the third channel section 202c. By using the longer conveying path of the bent channel and the larger sidewall friction, the weight of some powder materials is supported by the sidewall, and finally the pressure condition of the powder materials at the bottom is reduced, avoiding the powder materials at the lower part of the feeding channel 202 from being compacted and unable to be output. The second through hole 203 is inclined relative to the axis direction of the first channel section 202a or parallel to the first channel section 202a, so that there is a preset height difference at both ends of it. Its lower end is connected to the second channel section 202b, and its upper end is connected to the external atmospheric environment. Since there are turning structures at both the upper and lower parts of the second channel section 202b, the flow rate of the powder materials at the second channel section 202b is slow, and the end of the second through hole 203 connected to the external atmospheric environment is relatively high, which is conducive to reducing the possibility of the powder materials escaping from the second through hole 203 to the external environment and is convenient for use. In actual application, the specific structures of the feeding channel 202 and the second through hole 203 can be set accordingly according to actual use needs.

[0056] In some embodiments, buffers 130 are provided at both ends of the movement stroke of the material control seat 310 on the machine base 100, and the material control seat 310 can move to contact with the buffers 130.

[0057] It can be understood that, as Figure 1 and Figure 2 shown, there are two buffers 130 which are respectively arranged at the front and rear ends of the movement stroke of the material control seat 310. During use, the first driver 320 drives the material control seat 310 to move back and forth. When the material control seat 310 moves to the end position of its stroke, it contacts with the corresponding buffer 130, and the buffer 130 is used for buffering, which is beneficial to the deceleration and stop of the material control seat 310. At the same time, it can also better limit the movement stroke of the material control seat 310 and improve the use reliability. In actual application, the buffer 130 can be composed of an elastic member, such as a spring or other elastic materials. Or, the buffer 130 can be a cylinder. The specific structure of the buffer 130 can be set accordingly according to actual use needs and is not limited here.

[0058] In some embodiments, the silo mechanism 200 is provided with a viewing window 212 corresponding to the material cavity 201. The viewing window 212 is used for users to observe the powder material situation in the material cavity 201.

[0059] It can be understood that, as Figure 3 and Figure 4 shown, the viewing window 212 is arranged on the front side of the lower part of the material box 210. There are three viewing windows 212 which are respectively arranged corresponding to the three material cavities 201. During use, users can observe the remaining powder material in the corresponding material cavity 201 through the viewing window 212, so as to add the powder material of the corresponding mesh number in a timely manner, which is beneficial to ensuring the continuity of production and convenient for production use. In practical applications, in addition to setting the viewing window 212, corresponding sensors, such as pressure sensors, Hall sensors, etc., can also be set in the material cavity 201 to detect the remaining situation of the powder material in the material cavity 201, and through electrical connection to a display or a reminder to remind users to add the powder material of the corresponding mesh number in a timely manner. The specific structure of the viewing window 212 can be set accordingly according to actual use needs, and those skilled in the art should all understand.
