It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] As mentioned in the background section, in the prior art, chip conveyors and collection vehicles are mainly used to collect and transport various coiled, lumpy, and blocky chips, as well as materials such as copper chips, aluminum chips, stainless steel chips, and nylon chips. However, for graphite powder generated from graphite processing, jamming and graphite powder overflow are prone to occur during the conveying process; and during the collection process, graphite powder overflow and inconvenience in external transportation are also common problems. Therefore, this application provides a powder conveying and collection device. This device has a plate on the collection section with a feed inlet. The feed inlet is connected to the chip discharge port of the CNC machine tool through a first guide channel, reducing graphite powder overflow. Furthermore, the device also has a second guide pipe at the discharge port of the collection section. Through this second guide pipe, the graphite powder enters the collection section, further reducing powder overflow. Simultaneously, a chain and scraper are installed inside the collection chamber to prevent graphite powder from jamming within the chamber, improving the conveying efficiency of the device. The powder conveying and collecting device of this application will now be described in detail with reference to the accompanying drawings.

[0035] See Figures 1 to 7 As shown, according to an embodiment of the present invention, a powder conveying and collecting device is provided. This powder conveying and collecting device is at least used in a CNC machine tool (not shown in the figure), which is provided with a chip discharge port (not shown in the figure). The powder conveying and collecting device includes: a conveying assembly 10 and a collecting section 20.

[0036] In this embodiment, the conveying assembly 10 includes a collecting section 11 and a feeding mechanism 12. The collecting section 11 is provided with a closed collecting cavity 111, which is located along the first direction (i.e., Figures 1 to 5(In the x-direction shown), the first end of the collecting chamber 111 is provided with at least one inlet 11111, and the other end of the collecting chamber 111 is provided with an outlet 1112. The inlet 11111 and the chip discharge port are connected through a first guide pipe (not shown in the figure). The feeding mechanism 12 is disposed in the collecting chamber 111 and located between the inlet 11111 and the outlet 1112. The feeding mechanism 12 includes at least two chains 121, which are spaced apart along the first direction. There are multiple scrapers 122, and a chain 121 moves between the feed inlet 11111 and the discharge outlet 1112 to drive the scrapers 122 to move, so that the material in the collection chamber 111 is transported in the direction from the feed inlet 11111 to the discharge outlet 1112; the collection part 20 is provided at the bottom of the discharge outlet 1112, and the collection part 20 is provided with an inlet 21 and a closed collection chamber 22. The inlet 21 is connected to the collection chamber 22, and the inlet 21 is connected to the discharge outlet 1112 through a second guide pipe 23.

[0037] In actual operation, the enclosed collection chamber 111 on the collection section 11 of the powder conveying and collecting device is used to collect graphite powder discharged from the chip discharge port of the CNC machine tool. Specifically, along the first direction, at least one inlet 11111 is provided at the first end of the collection chamber 111. The inlet 11111 is connected to the chip discharge port through a first guide pipe, allowing the graphite powder to directly enter the interior of the collection chamber 111 through the enclosed environment, reducing graphite powder overflow. An outlet 1112 is provided at the other end of the collection chamber 111, and a collection section 20 is provided at the bottom of the outlet 1112. The collection section 20 is provided with an inlet 21 and an enclosed collection chamber 22. The inlet 21 and the outlet 1112 are connected by a second guide pipe 23, which further reduces the overflow of graphite powder when entering the collection section 20 and improves the collection efficiency of graphite powder. A feeding mechanism 12 is provided between the inlet 11111 and the outlet 1112. This feeding mechanism 12 includes at least two chains 121. Along a first direction, multiple scrapers 122 are spaced apart between adjacent chains 121. When the chains 121 move between the inlet 11111 and the outlet 1112, they drive the scrapers 122 to move, causing the material in the collection chamber 111 to be transported along the direction from the inlet 11111 to the outlet 1112, thereby entering the collection section 20. Because the graphite powder has a small particle size, the scrapers 122 are used to transport the graphite powder at the bottom of the collection chamber 111 to the outlet 1112, preventing the feeding mechanism 12 from jamming. In other words, the powder conveying and collecting device in this embodiment improves the efficiency of graphite powder conveying and collecting, reduces the overflow of graphite powder during collection and discharge, and avoids device malfunctions during the conveying process.

[0038] Furthermore, the feed inlet 11111 at the first end of the collecting chamber 111 can be one, two, three, etc. The specific number is not specifically limited in this application and can be designed according to actual production needs. Figure 1 and Figure 5 The illustration shows a case with two feed inlets 11111. Furthermore, in this embodiment, the chain 121 can be configured as two, three, four, etc. In this application, two chains 121 are used, with a scraper 122 positioned between adjacent chains 121, improving the working efficiency of the scraper 122 and ensuring the working stability of the feeding mechanism 12.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7 As shown, the powder conveying and collecting device also includes a dust removal device (not shown in the figure). A discharge port 24 is provided on the collecting section 20, which is connected to the dust removal device via a third guide pipe 25. An on / off valve 26 is installed within the third guide pipe 25. Specifically, by providing a discharge port 24 on the collecting section 20 and connecting it to the dust removal device via the third guide pipe 25, manual operation is reduced, the transfer efficiency of graphite powder within the collecting section 20 is improved, and graphite powder spillage is reduced. Furthermore, the on / off valve 26 is provided on the third guide pipe 25 to control the connection and closure of the third guide pipe 25 and the dust removal device. For example, the on / off valve 26 can be a butterfly valve, as butterfly valves have advantages such as simple structure, small size, light weight, quick opening and closing, and good regulating performance.

[0040] like Figure 6 and Figure 7 As shown, the collecting section 20 includes a collecting groove, and a cover plate 27 is provided on the collecting groove. The cover plate 27 includes a first cover plate 271 and a second cover plate 272. One side of the first cover plate 271 is fixedly connected to a first side of the collecting groove via a first hinge 28, and the second cover plate 272 is fixedly connected to a second side opposite to the first side via a second hinge 29. Both the first cover plate 271 and the second cover plate 272 are provided with a first handle portion 273. By providing the cover plate 27 on the collecting groove, a closed space is provided for the collecting section 20, reducing the possibility of graphite powder spillage. Setting the cover plate 27 to open in the middle improves the efficiency of maintenance and cleaning of the inside of the collecting groove. Furthermore, the first handle portion 273 on the cover plate 27 facilitates opening the cover plate 27. Support strips 2012 are also provided around the top of the collecting groove. The support strips 2012 support the cover plate 27, preventing it from falling into the collecting groove and also ensuring a better seal between the cover plate 27 and the collecting groove.

[0041] In this embodiment, the inlet 21 can be configured in three ways: the inlet 21 is provided on the first cover plate 271; or the inlet 21 is provided on the second cover plate 272; or, the first cover plate 271 has a first notch on the side near the second cover plate 272, and the second cover plate 272 has a second notch on the side near the first cover plate 271, with the first and second notches forming the inlet 21. In this embodiment, it is preferable to position the inlet 21 between the first cover plate 271 and the second cover plate 272. This can improve loading efficiency, ensure that the graphite powder is evenly distributed within the collection section 20, and avoid imbalance caused by overloading on one side. It can also optimize the space utilization within the collection section 20; enhance sealing performance, as the inlet 21 in the middle position makes it easier to achieve a good sealing design; and facilitate the maintenance and cleaning of the collection grooves of the collection section 20.

[0042] like Figure 6 and Figure 7 As shown, the collection unit 20 includes a movable cart 201, a collection groove disposed on the movable cart 201, casters 2001 disposed at the bottom of the movable cart 201, and a second hand-held part 2011 disposed on the movable cart 201. By configuring the collection unit 20 as a movable cart 201, with a collection groove and casters 2001 at its bottom, the mobility and operability of the collection unit 20 are improved. Specifically, a mounting plate 2013 is disposed on the movable cart 201, and the casters 2001 at the bottom are disposed below the mounting plate 2013, preventing bolts or other components from penetrating the collection groove during the installation of the casters 2001, thus avoiding a reduction in the sealing performance of the collection unit 20. These casters are swivel casters. Furthermore, during use, the mounting plate 2013 also provides support for the collection groove, preventing powder leakage due to insufficient structural strength of the collection groove caused by graphite powder entering the groove, thus avoiding adverse effects on the environment and personnel. A second hand-held part 2011 is also provided on the mobile vehicle 201, which is convenient for staff to operate.

[0043] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the collecting chamber 111 includes a collecting groove. The collecting groove is covered by a detachable plate 1111, which has at least one feed inlet 11111. The feed inlet 11111 is connected to the chip discharge port via a first guide pipe. The plate 1111 seals the collecting groove, creating a closed environment within the collecting chamber 111 and preventing graphite powder overflow during feeding. The detachable nature of the plate 1111 facilitates maintenance of the feeding mechanism 12 within the collecting chamber 111 and cleaning of the interior of the collecting chamber 111. Specifically, the number of feed inlets 11111 can be one, two, three, etc. Figure 1 and Figure 5 The diagram shows a case where there are two inlet ports 11111. For example, the shape of the inlet ports 11111 can be rectangular, square, or circular, depending on the shape of the guide pipe. Figure 1 and Figure 5 The image shows the case where the feed inlet 11111 is rectangular.

[0044] Furthermore, in this embodiment, the scraper 122 includes a straight section 1221 and a vertical section 1222 perpendicularly connected to the straight section 1221. The scraper 122 used in this embodiment is L-shaped. The L-shaped scraper 122 not only removes graphite powder from the bottom of the collecting chamber 111, but the vertical section 1222 also increases the conveying capacity of the graphite powder. In this embodiment, the straight section 1221 is parallel to the bottom of the collecting chamber 111. During actual installation of the scraper 122, a gap of 2mm-4mm is set between the straight section 1221 and the bottom of the collecting chamber 111. This reduces friction and wear between the scraper 122 and the bottom of the collecting chamber 111, while ensuring that most of the graphite powder does not pass through within this gap range. In addition, reserving a 2mm-4mm gap during installation can also prevent jamming between the scraper 122 and the bottom of the collecting chamber 111 due to manufacturing or installation errors, ensuring smooth equipment operation.

[0045] like Figures 1 to 3 As shown, the feeding mechanism 12 also includes a drive component 123 and a transmission roller (not shown in the figure). The drive component 123 can be a motor, cylinder, etc. In this application, it is preferred that the drive component 123 is a motor, as motor drive has better control accuracy and starting speed. Specifically, there are two transmission rollers, one of which is located at the first end of the collecting chamber 111, and the other is located at the second end of the collecting chamber 111. A chain 121 is wound between the two transmission rollers, and the drive component 123 is driven to one of the two transmission rollers to drive the chain 121 to rotate. This arrangement is beneficial for conveying the graphite powder at the inlet 11111 to the outlet 1112. At the same time, due to the rotation of the chain 121, the scraper 122 located between two adjacent chains 121 reduces the accumulation of graphite powder in the collecting chamber 111, avoiding the device from jamming.

[0046] like Figure 1 , Figure 2 and Figure 4As shown, the powder conveying and collecting device also includes a support part 30, which has an installation groove 31 for supporting a portion of the collection chamber 111. Specifically, the collection chamber 111 includes a horizontal section 1113 and an inclined section 1114 connected to the horizontal section 1113, wherein the horizontal section 1113 is installed in the installation groove 31. The installation groove 31 is formed by two parallel main plates, two parallel side plates, and a bottom plate. A parallel limiting plate 35 is provided between the two parallel main plates. When the horizontal section 1113 is installed in the installation groove 31, it is limited between the two limiting plates 35, preventing the collection chamber 111 from shifting and improving the working stability of the powder conveying and collecting device. The bottom plate also includes support plates arranged sequentially and at intervals between the two main plates. These support plates can reduce the contact area between the collection chamber 111 and the support part 30, reducing friction and wear between the collection chamber 111 and the support part 30. At least one third hand-held part 32 is also provided on the outer surface of the bearing part 30, through which the entire material collection part 11 can be moved to the actual feeding position. Exemplarily, the number of third hand-held parts 32 can be 1, 2, 3, 4, etc., and this application does not make a specific limitation, but can be selected according to actual production needs.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, along the first direction, the bottom of the supporting part 30 is provided with a plurality of roller assemblies 33 and a plurality of adjusting screws 34, and the plurality of adjusting screws 34 are connected to the plurality of roller assemblies 33 in a one-to-one correspondence. Exemplarily, the number of adjusting screws 34 and roller assemblies 33 can be 4, 6, 8, 10, etc., and the specific number is not limited in this application; it can be selected as needed in actual production. In this embodiment, an adjustable and slidable component is also provided at the bottom of the inclined section 1114 of the collecting chamber 111. Through the combined action of this component and the roller assemblies 33 and adjusting screws 34 provided on the supporting part 30, the collecting part 11 can be moved as a whole, and can be moved to the position where material collection is required according to actual production needs. Specifically, a threaded hole extending along the height direction of the powder conveying and collecting device is provided on the bearing part 30. An adjusting screw 34 is installed in the threaded hole. The adjusting screw 34 can move up and down along the length direction of the threaded hole to adjust the distance between the collecting chamber 111 and the chip discharge port of the CNC machine tool, thereby improving the collection of graphite powder generated by the CNC machine tool.

[0048] In summary, this application provides a plate 1111 on the collecting section 11, and at least one feed inlet 11111 on the plate 1111. A first guide pipe is provided between the feed inlet 11111 and the chip discharge port of the CNC machine tool. The graphite powder discharged from the chip discharge port enters the collecting chamber 111 through a closed space, reducing the overflow of graphite powder. A second guide pipe 23 is provided at the discharge port 1112 of the collecting section 11 and is closedly connected to the inlet 21 on the collecting section 20, further reducing the overflow of graphite powder discharged from the collecting section 11. This application also includes a feeding mechanism 12 within the collection chamber 111. The feeding mechanism 12 includes a drive roller, a chain 121, and a scraper 122. Driven by a motor, the chain 121 rotates back and forth between the inlet 11111 and the outlet 1112, driving the scraper 122 to move and transport the graphite powder in the collection chamber 111 from the inlet 11111 to the outlet 1112, thus preventing the feeding mechanism 12 from jamming. Furthermore, this application also includes a discharge port 24 on the collection section 20, and a third guide pipe 25 connects the discharge port 24 to the dust removal equipment. This facilitates the discharge of graphite powder from the collection section 20, reduces manual operation, and minimizes the occurrence of graphite powder overflow. The entire powder conveying and collecting device is equipped with rollers and adjusting screws 34, which improves the mobility of the powder conveying and collecting device and allows for the adjustment of the distance between the powder conveying and collecting device and the chip discharge port. This is more conducive to reducing the collection and conveying of graphite powder generated by CNC machine tools and improving the collection and conveying efficiency of graphite powder.
