In the blanking unit, the cavity for conveying materials is respectively provided in the feed piece and the blanking piece, and by controlling the relative lifting between the feed piece and the blanking piece and the cooperation between the two inclined surfaces, the blanking and blocking of materials are realized, and the blocking and blanking of materials can be realized more quickly.

[0040] Please refer to Figures 1 to 6 This embodiment provides a material discharge unit 100, which is mainly used to solve the problems of material blockage and slow material discharge in the prior art.

[0041] The unloading unit 100 includes a feed member 10 and a unloading member 20 that can be raised and lowered relative to each other. The feed member 10 is used to dock with an upstream device to receive materials transferred from the upstream device, while the unloading member 20 is used to dock with a downstream device to transfer materials to the downstream device. The feed member 10 includes a mounting portion 11 and a feed portion 12. A feed cavity 122 having a feed port 121 is provided in the feed portion 12. The mounting portion 11 is used to dock with a guide rail. The mounting portion 11 is a supporting mounting structure in the feed member 10. The feed portion 12 is used to dock with an upstream device to receive materials into the feed cavity 122 through the feed port 121. A discharge cavity 22 having a discharge port 21 is provided in the unloading member 20, and a blocking portion 23 is provided in the discharge cavity 22. The material can be discharged outward through the discharge port 21, thereby discharging the material in the unloading unit 100 to a downstream device.

[0042] The feed portion 12 is at least partially inserted into the discharge cavity 122. A first inclined surface 123 is provided at the bottom of the feed portion 12, and a second inclined surface 231 is provided at the top of the blocking portion 23. The inclined surface here refers to a surface that is not parallel or perpendicular to a horizontal plane after the discharge unit 100 is installed, but rather has a certain inclination angle relative to the horizontal plane.

[0043] By relative lifting between the feeding member 10 and the discharging member 20 , the first inclined surface 123 and the second inclined surface 231 can be attached to or separated from each other, so that the feeding cavity 122 and the discharging cavity 22 are blocked or connected. That is to say, by driving the feeding piece 10 and the blanking piece 20 to rise and fall relative to each other, the first inclined surface 123 and the second inclined surface 231 can be fitted together, thereby blocking the feeding chamber 122 and the discharging chamber 22, so that the material in the feeding chamber 122 cannot flow smoothly into the discharging chamber 22, thereby blocking the material in the feeding chamber 122 for temporary storage, thereby achieving sealing of the material; and by driving the feeding piece 10 and the blanking piece 20 to rise and fall relative to each other, the first inclined surface 123 and the second inclined surface 231 can be separated, thereby connecting the feeding chamber 122 and the discharging chamber 22, so that the material in the feeding chamber 122 can flow smoothly into the discharging chamber 22, thereby transporting the material outward through the discharge port 21 to achieve blanking.

[0044] In this embodiment, when the feeding member 10 and the discharging member 20 are lifted and lowered relative to each other, the two relative inclined surfaces are fitted together, so that the feeding cavity 122 can be blocked more quickly, thereby blocking the material more quickly; at the same time, through the cooperation between the two relative inclined surfaces, the material can fall from the feeding cavity 122 into the discharging cavity 22 more quickly during separation, thereby achieving faster material dropping.

[0045] Preferably, in one embodiment, two feed parts 12 are provided, and each feed part 12 is provided with the feed cavity 122. Two independent discharge cavities 22 are provided in the blanking member 20, and each discharge cavity 22 is provided with the blocking part 23. The two independent discharge cavities 22 refer to the two discharge cavities 22 being isolated from each other and not conducting, thereby preventing the materials in the two discharge cavities 22 from mixing. The two feed parts 12 are correspondingly inserted into the two discharge cavities 22, that is, each feed part 12 is correspondingly inserted into one discharge cavity 22. That is to say, in this embodiment, the blanking unit 100 can simultaneously accommodate two groups of materials and discharge two groups of materials. When feeding, the materials can be received separately through the two feed parts 12, and when blanking, the materials can be output separately through the two discharge cavities 22.

[0046] Preferably, in one embodiment, the feed port 121 is located at the top of the feed cavity 122, and the discharge port 21 is located at the bottom of the discharge cavity 22, so that the material can be better received and guided by gravity. At the same time, when the material is dropped, the drop can be smoother to avoid jamming and blocking.

[0047] Preferably, in one embodiment, the second inclined surface 231 is inclined toward the discharge port 21. That is, the bottom end 2311 of the second inclined surface 231 is located relatively close to the discharge port 21, while the top end 2312 of the second inclined surface 231 is located relatively far from the discharge port 21. Therefore, when the material falls onto the second inclined surface 231, the second inclined surface 231 can guide the material into the discharge port 21, thereby better avoiding material jamming or blocking.

[0048] Preferably, in one embodiment, the cavity diameter of the feed chamber 122 gradually decreases from top to bottom. That is to say, the feed chamber 122 is a structure with a gradually decreasing size, and the cavity diameter of the uppermost portion of the feed chamber 122 is the largest, while the cavity diameter of the lowermost portion of the feed chamber 122 is the smallest. Through this structure, the feed chamber 122 can more stably receive the material sent out by the upstream device, and after receiving the material, it can gradually guide the material downward, further avoiding material jamming and blocking. More preferably, at least one of the walls surrounding the feed chamber 122 is an inclined wall, so that the material can be better guided gradually downward to prevent jamming and blocking.

[0049] Preferably, in one embodiment, the diameter of the discharge port 21 is smaller than the diameter of the discharge cavity 22, that is, the discharge port 21 is the smallest part of the discharge cavity 22. Through this structure, the material can be more concentrated during the blanking process, avoiding the dispersion of the material, and the material can be delivered to the filter rod more smoothly.

[0050] Preferably, in one embodiment, a lifting guide assembly 30 is provided between the feed member 10 and the blanking member 20. The lifting guide assembly 30 includes a first guide member 31 and a second guide member 32 that can slide relative to each other. The first guide member 31 is provided on the feed member 10, and the second guide member 32 is provided on the blanking member 20. The provision of the lifting guide assembly 30 can better guide the relative movement direction between the feed member 10 and the blanking member 20. Specifically, in one embodiment, the first guide member 31 can be a slider, and the second guide member 32 can be a guide rail.

[0051] Preferably, in one embodiment, a cam follower 40 is provided on the blanking member 20. After the blanking member 20 is installed, it can be supported on the guide rail by the cam follower 40. During the movement of the blanking unit 100, the cam follower 40 can roll on the guide rail, thereby avoiding wear between the blanking member 20 and the guide rail, thereby better improving the service life.

[0052] At the same time, in one embodiment, a material removal device is also provided, comprising the material removal unit 100, a downward pressing guide rail, and a positioning guide rail. One of the feed member 10 and the material removal member 20 is mounted on the downward pressing guide rail, and the other is mounted on the positioning guide rail. That is, when the feed member 10 is mounted on the downward pressing guide rail, the material removal member 20 is mounted on the positioning guide rail; when the material removal member 20 is mounted on the downward pressing guide rail, the feed member 10 is mounted on the positioning guide rail. A height difference exists in some areas of the downward pressing guide rail. As the material removal unit 100 moves along the downward pressing guide rail, the downward pressing guide rail can drive the feed member 10 (or the material removal member 20) to rise or fall, thereby controlling the relative rise and fall between the feed member 10 and the material removal member 20, thereby achieving material blocking or blanking of the material removal unit 100. Specifically, in one embodiment, both the downward pressing guide rail and the positioning guide rail are annular guide rails.

[0053] Preferably, in one embodiment, the blanking member 20 is mounted on the pressing guide rail via the cam follower 40. That is, in this embodiment, the blanking member 20 is mounted on the pressing guide rail, and the pressing guide rail controls the lifting and lowering of the blanking member 20 at different positions, thereby achieving the dropping or blocking of materials in the blanking unit 100 at the corresponding positions.

[0054] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
