Powder device

Abstract

This application relates to the field of powder processing technology and provides a powder processing device, including a base, a cylinder, a powder processing component, and a first drive component. Multiple powder chambers in the cylinder can accommodate powder. The first drive component drives the cylinder to move relative to the base, allowing each of the multiple powder chambers to face a pressing component. When a powder chamber faces a pressing chamber, the pressing component moves towards the bottom wall of the powder chamber to compress the powder within the chamber into a powder cake. This allows powder from multiple chambers to be compressed into powder cakes. After extraction of the powder cakes from multiple chambers, all powder cakes can be processed uniformly, eliminating the need for separate cleaning of powder cakes after extraction from a single chamber, thus improving the powder processing efficiency of the device.

The first driving component drives the cylinder to move relative to the base, allowing the multiple powder chambers of the cylinder to be respectively aligned with the powder pressing component. When the powder chambers are aligned with the powder pressing chambers, the powder pressing component can move towards the bottom wall of the powder chamber to compress the powder in the powder chamber into a powder cake. In this way, the powder in multiple powder chambers can be compressed into a powder cake. After the powder cakes in multiple powder chambers are extracted, the powder cakes in multiple powder chambers can be processed uniformly. This eliminates the need to clean the powder cakes separately after extraction in a single powder chamber, thus improving the powder processing efficiency of the powder processing device of this application.

[0087] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0088] Fully automatic coffee machines can automatically grind, dispense, tamp, and extract coffee. To improve the efficiency of fully automatic coffee machines, they can be equipped with multiple extraction tanks, which can sequentially dispense, tamp, and extract coffee.

[0089] Currently, fully automatic coffee machines require separate cleaning of the residue left behind after each extraction cylinder completes the coffee brewing process, which limits the efficiency of these machines.

[0090] In the powder processing device proposed in this application, multiple powder chambers of the cylinder can accommodate powder. The first driving assembly drives the cylinder to move relative to the base, allowing each powder chamber to be opposite to a pressing component. When a powder chamber is opposite a pressing chamber, the pressing component can move towards the bottom wall of the powder chamber to compress the powder within the chamber into a powder cake. This allows powder from multiple chambers to be compressed into powder cakes. After extraction of the powder cakes from multiple chambers, the powder cakes from all chambers can be processed uniformly, eliminating the need for separate cleaning of powder cakes after extraction from a single chamber, thus improving the powder processing efficiency of the powder processing device of this application.

[0091] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0092] This application discloses a powder processing device, with reference to... Figures 1 to 3A As shown, it includes a base 100, a cylinder 200, a powder tamping component 310, and a first drive assembly 400. This powder tamping device is used in coffee machines or other beverage preparation devices.

[0093] The base 100 serves as the fundamental component of the powder handling device of this application, providing a mounting foundation for at least some other components of the powder handling device. The base 100 can be made of metal, giving it superior structural strength and thus improved durability and reliability. Alternatively, the base 100 can be made of polymer materials, achieving a certain structural strength while maintaining a relatively light weight. Furthermore, the base 100 can also employ a combination of metal and polymer materials. Specifically, the main structure of the base 100, as well as parts susceptible to external impact or damage, can be made of metal, while other parts can be made of polymer materials. This allows the base 100 to achieve good structural strength without excessive weight, thereby reducing the weight of the powder handling device.

[0094] The base 100 has a powder channel and a discharge port 140 connected to the powder channel. The main base 100 is configured to output powder through the discharge port 140. Specifically, the base 100 has a grinding mechanism inside and may also have a feed port, through which large-diameter raw materials or lumpy raw materials can be fed into the base 100. The grinding mechanism inside the base 100 can grind large-diameter raw materials or lumpy raw materials into powder, and output the ground powder through the powder channel and the discharge port 140. The grinding mechanism can be a grinding blade; the rotation of the grinding blade can cut and crush the raw material to form powder.

[0095] The cylinder body 200 is movably connected to the base 100, allowing the cylinder body 200 to move relative to the base 100 under drive. The cylinder body 200 has multiple powder chambers 210, which are internal structures of the base 100 and can be used to load powder. Correspondingly, the cylinder body 200 also has openings communicating with the powder chambers 210. Any one of the multiple powder chambers 210 of the cylinder body 200 can be opposite to the discharge port 140 of the base 100, allowing the ground powder to be conveyed into the powder chamber 210 through the discharge port 140.

[0096] Specifically, the powder chamber 210 of the cylinder 200 can be located on the bottom side of the discharge port 140 of the base 100. The discharge port 140 is located on the bottom side of the powder channel 120 of the base 100, and the powder output from the discharge port 140 can fall into the powder chamber 210 under the action of gravity. In this way, there is no need to set up additional components in the base 100 for conveying the powder into the powder chamber 210, which simplifies the structure of the base 100 and makes the cost of the powder device of this application lower.

[0097] Of course, it should be understood that when the base 100 does not have a powder channel and a discharge port 140, powder can be conveyed into the powder chamber 210 through other devices or by manual addition by the user.

[0098] A powder processing component 300 is disposed on the base 100, and can process the powder in the powder chamber 210. A first drive component 400 can drive a cylinder to move relative to the base 100, such that the opening of any one of the multiple powder chambers 210 of the cylinder body 200 can be opposite to the powder processing component 300. At this time, the powder processing component 300 can perform corresponding processing on the powder in the powder chamber 210.

[0099] After the powder in one of the multiple powder chambers 210 is processed by the powder processing component 300, the first drive component 400 can drive the cylinder 200 to move so that the opening of another powder chamber 210 is opposite to the powder processing component 300, allowing the powder processing component 300 to process the powder in the other powder chamber 210. As the first drive component 400 continues to drive the cylinder 200 to move relative to the base 100, the openings of the multiple powder chambers 210 can be sequentially aligned with the powder processing component 300, thereby ensuring that the powder in all multiple powder chambers 210 can be processed by the powder processing component 300.

[0100] After the powder in the powder chamber 210 is processed into waste by the powder processing component 300, the waste needs to be cleaned out of the powder chamber 210. Since multiple powder chambers 210 are located inside the cylinder 200, after the powder in multiple powder chambers 210 has been processed, the waste in multiple powder chambers 210 can be cleaned out at the same time. In this way, the waste in multiple powder chambers 210 can be processed at the same time after the cylinder 200 and the base 100 are disassembled, without having to disassemble the cylinder 200 multiple times to process the waste in the powder chambers 210, thus improving the efficiency of the powder processing device of this application.

[0101] Specifically, the powder processing assembly 300 of this application may include a powder pressing component 310, which is movably disposed on the base 100. A first drive assembly 400 is disposed on the base 100 and connected to the cylinder 200. The first drive assembly 400 can drive the cylinder 200 to move relative to the base 100, such that the opening of any one of the multiple powder chambers 210 of the cylinder 200 can be opposite to the powder pressing component 310. At this time, the powder pressing component 310 can be driven to move towards the bottom wall of the powder chamber 210, i.e. Figure 3A The powder pressing component 310 moves in the X direction, allowing it to move into the powder cavity 210 and squeeze the powder inside. As the powder pressing component 310 continues to move toward the bottom wall of the powder cavity 210, the powder inside the powder cavity 210 can be continuously compressed to form a powder cake structure.

[0102] When the powder in one of the multiple powder chambers 210 is compressed by the powder pressing component 310 to form a powder cake structure, the first driving assembly 400 can drive the cylinder 200 to move until the opening of another powder chamber 210 is opposite to the powder pressing component 310, so that the powder pressing component 310 can move towards the bottom wall of the other powder chamber 210 to compress the powder in the other powder chamber 210 to form a powder cake structure. As the first driving assembly 400 continues to drive the cylinder 200 to move relative to the base 100, the openings of the multiple powder chambers 210 can be sequentially opposite to the powder pressing component 310, so that the powder in the multiple powder chambers 210 can be compressed by the powder pressing component 310 to form a powder cake structure.

[0103] When the powder is coffee powder, liquid can be injected into the powder chamber 210 to allow the coffee pouch to be extracted, thus producing concentrated coffee. After extraction, the coffee pouch becomes waste and needs to be cleaned from the powder chamber 210. Since multiple powder chambers 210 are located within the cylinder 200, after extraction is complete in all powder chambers 210, the coffee pouches in all powder chambers 210 can be cleaned all at once. This allows for the unified disposal of waste from multiple powder chambers 210 by disassembling the cylinder 200 and the base 100, eliminating the need for repeated disassembly of the cylinder 200 to handle the waste in the powder chambers 210, thereby improving the efficiency of the powder device of this application.

[0104] Specifically, the powder chamber 210, facing away from the powder pressing component 310, can be provided with a liquid inlet and a liquid outlet. Liquid is injected into the powder chamber 210 through the liquid inlet, and the extracted liquid after extraction can be discharged out of the powder chamber 210 through the liquid outlet. The liquid inlet can be located at the bottom of the powder chamber 210.

[0105] refer to Figures 3A to 3C As shown, the powder processing assembly 300 of this application may also include a powder conveying component 320, which may be disposed on the base 100, specifically within the powder channel of the base 100. The conveying end of the powder conveying component 320 may be opposite to the discharge port 140 of the base 100. The first driving assembly 400 may drive the cylinder 200 to move relative to the base 100, such that the opening of any one of the multiple powder chambers 210 of the cylinder 200 may be opposite to the powder conveying component 320. At this time, the powder conveying component 320 may convey powder into the powder chamber 210 through the discharge port 140.

[0106] The first drive assembly 400 drives multiple powder chambers 210 to face the discharge port 140 respectively, and the powder conveying component 320 can convey powder into the multiple powder chambers 210 respectively.

[0107] Specifically, the first drive assembly 400 can first drive one of the multiple powder chambers 210 to face the outlet 140 of the base 100, and the powder conveying component 320 can convey and separate the powder into the powder chamber 210. After the powder is conveyed into the powder chamber 210, the first drive assembly 400 can drive the cylinder 200 to move relative to the base 100, so that the powder chamber 210 moves to face the powder pressing component 310. The powder pressing component 310 can move towards the bottom wall of the powder chamber 210 to compress the powder in the powder chamber 210 into a powder cake structure. By driving the multiple powder chambers 210 to face the outlet 140 of the base 100 in sequence by the first drive assembly 400, each of the multiple powder chambers 210 can be filled with powder, and the powder is compressed into a powder cake structure by the powder pressing component 310.

[0108] In some implementations, reference Figure 2 and Figure 3A As shown, the cylinder 200 of this application is rotatably connected to the base 100, allowing the cylinder 200 to rotate relative to the base 100. Multiple powder chambers 210 of the cylinder 200 are spaced apart around the rotatable connection between the cylinder 200 and the base 100. Correspondingly, after the first drive assembly 400 drives the cylinder 200 to rotate around the rotatable connection between the cylinder 200 and the base 100, the multiple powder chambers 210 can sequentially face the powder pressing component 310. By allowing the cylinder 200 to rotate relative to the base 100, the range of motion of the cylinder 200 relative to the base 100 can be reduced, making the structure of the powder processing device of this application more compact.

[0109] Specifically, the cylinder 200 of this application can be configured as a quasi-cylindrical structure, so that when the cylinder 200 rotates relative to the base 100, the position of the rotational connection between the cylinder 200 and the base 100 will not change, and the outer circumference of the cylinder 200 is within the same circumference range, so that the range of motion of the cylinder 200 is relatively smaller.

[0110] Of course, in other embodiments, the cylinder 200 may also adopt a multi-prism structure, which makes the range of motion of the cylinder 200 during rotation relatively small, making the structure of the powder device of this application more compact.

[0111] In some embodiments, the cylinder 200 includes a first powder chamber 210a and a second powder chamber 210b among its multiple powder chambers 210. When the first powder chamber 210a is opposite to the powder pressing member 310, the second powder chamber 210b is opposite to the powder conveying member 320. This ensures that two of the multiple powder chambers 210 can be simultaneously opposite to the powder conveying member 320 and the powder pressing member 310, respectively. This allows for the simultaneous conveying of powder into the powder chambers 210 and the compression of the powder into a powder cake structure, thereby improving the separation efficiency of the powder processing device of this application.

[0112] In some embodiments, the first powder chamber 210a and the second powder chamber 210b can be arranged adjacent to each other. In this way, when the powder conveying member 320 conveys powder into any one of the powder chambers 210, the powder chamber 210 can be opposite the powder pressing member 310 when the first driving assembly 400 drives the cylinder 200 to rotate at the minimum angle. This improves the continuity of powder processing in the powder chamber 210 and thus improves the processing efficiency of the powder device of this application.

[0113] In some implementations, reference Figure 2 and Figure 3A As shown, to further compact the structure of the powder apparatus of this application, the first drive assembly 400 can be connected to the powder pressing component 310. When the opening of the powder cavity 210 is opposite to the powder pressing component 310, the first drive assembly 400 is configured to drive the powder pressing component 310 to move toward the bottom wall of the powder cavity 210. By having the first drive assembly 400 drive the powder pressing component 310 to move toward the bottom wall of the powder cavity 210, it is not necessary to separately provide an assembly for driving the powder pressing component 310 to move toward the bottom wall of the powder cavity 210. This reduces the number of components in the powder apparatus of this application, simplifies the structure of the powder apparatus, and makes the manufacturing cost of the powder apparatus lower and the structure more compact.

[0114] In some embodiments, in order for the first drive assembly 400 to drive the powder pressing component 310 to move toward the bottom wall of the powder chamber 210 of the cylinder 200, the first drive assembly 400 may include a driver 410 and a first transmission member 420. The driver 410 has an output end, the output end of the driver 410 is rotatable, and the output end of the driver 410 is connected to the powder pressing component 310 through the first transmission member 420. The first transmission member 420 can convert the rotational force of the output end of the driver 410 into a force that drives the powder pressing component 310 to move toward the bottom wall of the powder chamber 210 of the cylinder 200.

[0115] Specifically, the driver 410 can be a motor, and the output end of the driver 410 is the output shaft of the motor. The cost of a motor is relatively low, which can reduce the cost of the first drive assembly 400, thereby reducing the manufacturing cost of the powder processing device of this application.

[0116] In some implementations, reference Figures 2 to 4 As shown, in order for the first transmission member 420 to convert the rotational force of the output end of the driver 410 into a force that drives the powder pressing member 310 to move toward the bottom wall of the powder chamber 210, the first transmission member 420 may be provided with a first transmission part 421 and a first transmission rod 422. The first transmission part 421 is sleeved on the first transmission rod 422, and the first transmission part 421 and the first transmission rod 422 are threadedly connected. One end of the first transmission rod 422 is connected to the powder pressing member 310, and the first transmission part 421 is connected to the output end of the driver 410.

[0117] The first transmission part 421 and the first transmission rod 422 can form a threaded screw structure. After the driver 410 drives the first transmission part 421 to rotate, the first transmission rod 422 can move relative to the first transmission part 421 along the axis of the first transmission rod 422. The axial direction of the first transmission rod 422 is the direction opposite to the bottom wall of the powder pressing component 310 and the powder chamber 210 of the cylinder 200. Thus, after the output end of the driver 410 rotates, it can drive the first transmission rod 422 to move, thereby causing the powder pressing component 310 to move towards the bottom wall of the powder chamber 210, thereby extruding the powder in the powder chamber 210 to form a powder cake structure.

[0118] The thread helix angle of the first transmission rod 422 can be set from 6 degrees to 15 degrees. In this way, when the first transmission part 421 does not rotate, the first transmission rod 422 and the first transmission part 421 can be relatively fixed to achieve self-locking.

[0119] In some embodiments, in order for the driver 410 of this application to drive the first transmission part 421 to rotate, the first transmission member 420 may also be provided with a second transmission part 423. The second transmission part 423 and the first transmission part 421 are both gears, and the second transmission part 423 meshes with the first transmission part 421. The second transmission part 423 is connected to the output end of the driver 410.

[0120] Specifically, the axis of the output end of the driver 410 coincides with the axis of the second transmission part 423. After the driver 410 drives the second transmission part 423 to rotate, the first transmission part 421 can be driven to rotate.

[0121] By providing the second transmission part 423, the driver 410 can avoid the first transmission rod 422 and the first transmission part 421, making the arrangement of the first transmission rod 422 and the first transmission part 421 more flexible.

[0122] In some implementations, reference Figures 2 to 5 As shown, in order to enable the first drive assembly 400 of this application to also drive the cylinder 200 to rotate, the powder device of this application may further include a connecting shaft 500, which is connected to the cylinder 200. Multiple powder chambers 210 of the cylinder 200 are spaced apart around the connecting shaft 500. The connecting shaft 500 is rotatably connected to the base 100, allowing the cylinder 200 as a whole to rotate relative to the base 100 via the connecting shaft 500. The first drive assembly 400 is connected to the connecting shaft 500, and the first drive assembly 400 can drive the connecting shaft 500 to rotate, thereby causing the cylinder 200 to rotate as a whole, and thus the multiple powder chambers 210 of the cylinder 200 can also rotate.

[0123] Multiple powder chambers 210 can be evenly distributed around the connecting shaft 500, so that the first drive assembly 400 can drive the cylinder 200 to rotate in the same direction and at the same angle multiple times, so that the multiple powder chambers 210 are respectively opposite to the powder pressing component 310 or the powder conveying component 320 in the powder processing assembly 300.

[0124] In addition, in other embodiments, adjacent powder chambers 210 may be provided with different spacing, so that the first drive assembly 400 drives the cylinder 200 to rotate at different angles each time, so that the multiple powder chambers 210 are respectively opposite to the powder pressing component 310 or the powder conveying component 320 in the powder processing assembly 300.

[0125] Specifically, the connecting shaft 500 can be detachably or fixedly connected to the main body of the cylinder 200, and this application does not limit this. The connecting shaft 500 can pass through the center of the cylinder 200, and the connecting shaft 500 is the rotatable connection point between the cylinder 200 and the base 100. The multiple powder chambers 210 of the cylinder 200 can rotate around the axis of the connecting shaft 500, and correspondingly, the multiple powder chambers 210 of the cylinder 200 can be respectively opposite to the powder pressing component 310.

[0126] In some implementations, reference Figures 2 to 5 As shown, the first drive assembly 400 in this application also includes a second transmission member 430, which is connected to the first transmission rod 422. Accordingly, when the first transmission rod 422 is driven to rotate along its axial direction, the second transmission member 430 can move accordingly. When the second transmission member 430 moves along the axial direction of the first transmission rod 422, it can drive the connecting shaft 500 to rotate, thereby allowing the multiple powder chambers 210 of the cylinder 200 to be respectively opposite to the powder pressing member 310.

[0127] In some implementations, reference Figure 6 As shown, the connecting shaft 500 of this application has a first guide surface 521a. The first guide surface 521a is spirally arranged around a first axis, and the first axis is arranged at an angle to the axis of the connecting shaft 500. The first axis is... Figure 6 In the Y direction, the axis connecting shaft 500 is... Figure 6 In the X direction. When the first transmission rod 422 drives the second transmission member 430 to move in a first direction parallel to the axis of the connecting shaft 500, the second transmission member 430 can move to contact the first guide surface 521a, and the second transmission member 430 can move along the first guide surface 521a, so that the connecting shaft 500 rotates in a preset circumferential direction in the same direction as the circumferential direction of the connecting shaft 500.

[0128] Specifically, the first guide surface 521a has a curved structure, and the first guide surface 521a extends along a direction that forms an angle with the axis of the connecting shaft 500, so that the first guide surface 521a extends both circumferentially and axially along the connecting shaft 500.

[0129] When the first transmission rod 422 drives the second transmission member 430 to move along a first direction parallel to the axis of the connecting shaft 500, the second transmission member 430 exerts a force along the first direction. When the second transmission member 430 contacts the first guide surface 521a, the second transmission member 430 and the first guide surface 521a abut against each other. The first guide surface 521a can convert part of the force exerted by the second transmission member 430 along the first direction into a force that drives the connecting shaft 500 to rotate in a preset circumferential direction, thereby allowing the connecting shaft 500 to rotate in the preset circumferential direction. As a result, the cylinder body 200 as a whole can rotate around the axis of the connecting shaft 500, and the multiple powder chambers 210 of the cylinder body 200 can be rotated to be opposite the powder pressing member 310.

[0130] In some implementations, reference Figure 7 As shown, the second transmission member 430 of this application may be provided with a first transmission surface 431. When the second transmission member 430 contacts the first guide surface 521a, the first transmission surface 431 and the first guide surface 521a are in contact. In this way, there is no gap between the first transmission surface 431 and the first guide surface 521a, which makes the contact effect between the second transmission member 430 and the first guide surface 521a better, the interaction between the second transmission member 430 and the first guide surface 521a smoother, and the second transmission member 430 drives the connecting shaft 500 to rotate more smoothly.

[0131] Specifically, the first transmission surface 431 can also be configured as a curved surface structure, and the curved surface structure of the first transmission surface 431 matches the curved surface structure of the first guide surface 521a, so that the first transmission surface 431 can be fitted to the first guide surface 521a.

[0132] In some implementations, reference Figure 6 As shown, the connecting shaft 500 of this application may be provided with a second guide surface 522a. The second guide surface 522a is spirally arranged around a second axis, and the second axis is arranged at an angle to the axis of the connecting shaft 500. The second axis is... Figure 6 The Z direction. The first guide surface 521a and the second guide surface 522a are distributed along the axis of the connecting shaft 500.

[0133] When the first transmission rod 422 drives the second transmission member 430 to move along a second direction that is parallel to the axis of the connecting shaft 500 and opposite to the first direction, the second transmission member 430 can move to contact the second guide surface 522a, and the second transmission member 430 can move along the second guide surface 522a so that the connecting shaft 500 rotates in a preset circumferential direction that is in the same direction as the circumferential direction of the connecting shaft 500.

[0134] Specifically, the second guide surface 522a has a curved structure, and the second guide surface 522a extends along a direction that forms an angle with the axis of the connecting shaft 500, so that the second guide surface 522a extends both circumferentially and axially along the connecting shaft 500.

[0135] When the first transmission rod 422 drives the second transmission member 430 to move in a second direction parallel to the axis of the connecting shaft 500, the second transmission member 430 exerts a force in the second direction. When the second transmission member 430 contacts the second guide surface 522a, the second transmission member 430 and the second guide surface 522a abut against each other. The second guide surface 522a can convert part of the force exerted by the second transmission member 430 in the second direction into a force that drives the connecting shaft 500 to rotate in a preset circumferential direction, thereby allowing the connecting shaft 500 to rotate in the preset circumferential direction. As a result, the cylinder body 200 as a whole can rotate around the axis of the connecting shaft 500, and the multiple powder chambers 210 of the cylinder body 200 can be rotated to be opposite the powder pressing member 310.

[0136] By rotating the drive end of the driver 410 in two opposite directions, the first transmission rod 422 can be moved in either the first or second direction. This causes the second transmission member 430 to move in either the first or second direction. When the second transmission member 430 moves in either the first or second direction, it drives the connecting shaft 500 to rotate, causing the cylinder 200 to rotate as a whole. This allows the first transmission rod 422 to reciprocate, reducing its range of motion and making the first drive assembly 400 more compact in all states, thus making the powder processing device of this application more compact.

[0137] In some implementations, reference Figure 7 As shown, the second transmission member 430 of this application may be provided with a second transmission surface 432. When the second transmission member 430 contacts the second guide surface 522a, the second transmission surface 432 and the second guide surface 522a are in close contact. In this way, there is no gap between the second transmission surface 432 and the second guide surface 522a, which makes the contact effect between the second transmission member 430 and the second guide surface 522a better, the interaction between the second transmission member 430 and the second guide surface 522a smoother, and the second transmission member 430 drives the connecting shaft 500 to rotate more smoothly.

[0138] Specifically, the second transmission surface 432 can also be configured as a curved surface structure, and the curved surface structure of the second transmission surface 432 matches the curved surface structure of the second guide surface 522a, so that the second transmission surface 432 can be fitted to the second guide surface 522a.

[0139] In some embodiments, the connecting shaft 500 and the second transmission member 430 of this application may be made of polymer materials, specifically plastic materials. The first guide surface 521a and the second guide surface 522a may be configured as smooth surfaces or rough surfaces, and this application does not impose any restrictions on this. Correspondingly, the first transmission surface 431 and the second transmission surface 432 of the second transmission member 430 may also be configured as smooth surfaces or rough surfaces.

[0140] In some implementations, reference Figure 6 As shown, there are multiple first guide surfaces 521a and multiple second guide surfaces 522a, and these multiple first guide surfaces 521a and multiple second guide surfaces 522a are all spaced apart circumferentially along the connecting shaft 500. A preset plane is defined, which is perpendicular to the axis of the connecting shaft 500, i.e., perpendicular to... Figure 6 The X direction is perpendicular to it.

[0141] The orthographic projection of multiple first guide surfaces 521a onto a preset plane is the first projection, and the orthographic projection of multiple second guide surfaces 522a onto the preset plane is the second projection. The multiple first projections and multiple second projections are alternately arranged along the axial direction of the connecting shaft 500.

[0142] Specifically, when the first guide surface 521a slides relative to the second transmission member 430 until the first guide surface 521a separates from or is about to separate from the second transmission member 430, the second guide surface 522a faces the second transmission surface 432 of the second transmission member 430. In this way, after the first transmission rod 422 moves along the second direction, the second guide surface 522a can contact the second transmission member 430, and as the first transmission rod 422 continues to move along the second direction, the connecting shaft 500 can rotate in a preset circumferential direction.

[0143] When the second guide surface 522a slides relative to the second transmission member 430 until the second guide surface 522a separates from or is about to separate from the second transmission member 430, the first guide surface 521a faces the first transmission surface 431 of the second transmission member 430. In this way, after the first transmission rod 422 moves along the first direction, the first guide surface 521a can contact the second transmission member 430, and as the first transmission rod 422 continues to move along the first direction, the connecting shaft 500 can continue to rotate along a preset circumferential direction.

[0144] As a result, when the first transmission rod 422 reciprocates along the first direction or the second direction, the connecting shaft 500 can continuously rotate along the preset circumferential direction.

[0145] In some implementations, reference Figure 6As shown, in the circumferential direction of the connecting shaft 500, each side of any first projection coincides with two adjacent second projections. Specifically, when the second transmission member 430 slides along any preset first guide surface 521a until the first guide surface 521a is nearly separated from the second transmission member 430, the second guide surface 522a adjacent to the preset first guide surface 521a can be opposite to the second transmission surface 432 of the second transmission member 430. This ensures that after the second transmission member 430 moves in the second direction, the second guide surface 522a can contact and engage with the second transmission member 430.

[0146] When the second transmission member 430 slides along any preset second guide surface 522a until the second guide surface 522a is close to separating from the second transmission member 430, the first guide surface 521a adjacent to the preset second guide surface 522a can be opposite to the first transmission surface 431 of the second transmission member 430. This ensures that the first guide surface 521a can contact and cooperate with the second transmission member 430 after the second transmission member 430 moves along the first direction.

[0147] In some embodiments, the number of the first guide surface 521a and the second guide surface 522a of this application are the same, and the number of the first guide surface 521a and the second guide surface 522a is an integer multiple of the number of powder chambers 210 of the cylinder body 200.

[0148] Along the circumference of the connecting shaft 500, the first guide surface 521a has a first end and a second end. During the process of the second transmission member 430 moving from contact with the first end of the first guide surface 521a to separation from the second end of the first guide surface 521a, the connecting shaft 500 rotates by a first angle. The second guide surface 522a has a third end and a fourth end. During the process of the second transmission member 430 moving from contact with the third end of the second guide surface 522a to separation from the fourth end of the second guide surface 522a, the connecting shaft 500 rotates by a second angle. The sum of the first angle and the second angle is the third angle, and the angle between the center of two adjacent powder chambers 210 and the line connecting the connecting shaft 500 is the fourth angle. The third angle and the fourth angle are the same. This allows the cylinder 200 to rotate so that after the second transmission member 430 slides into contact with the adjacent first guide surface 521a and second guide surface 522a, the cylinder 200 can rotate to switch from one powder chamber 210 being opposite the powder pressing member 310 to the other adjacent powder chamber 210 being opposite the powder pressing member 310.

[0149] Specifically, when there are 5 powder chambers 210, the fourth angle between adjacent powder chambers 210 is 72 degrees, and the corresponding third angle, which is the sum of the first and second angles, is also 72 degrees. When there are 6 powder chambers 210, the fourth angle between adjacent powder chambers 210 is 60 degrees, and the corresponding third angle, which is the sum of the first and second angles, is also 60 degrees.

[0150] In this application, the helix angle of the first guide surface 521a, the second guide surface 522a, the first transmission surface 431, and the second transmission surface 432 can be set to 10 degrees to 80 degrees, so that the second transmission component 430 can cooperate with the first guide surface 521a and the second guide surface 522a to make the connecting shaft 500 rotate smoothly.

[0151] In some embodiments, the first transmission surface 431 and the second transmission surface 432 of this application are respectively located on the upper and lower sides of the second transmission member 430 in the first direction or the second direction. The connecting shaft 500 may be provided with a groove located between adjacent second guide surfaces 522a. Specifically, the connecting shaft 500 has a plurality of protruding second guide portions 522 and a plurality of first guide portions 521. The first guide surface 521a is disposed on the first guide portion 521, and the second guide surface 522a is disposed on the second guide surface 522. Among the plurality of second guide portions 522 of the connecting shaft 500, a groove 530 may be provided between adjacent second guide portions 522. When the second transmission member 430 moves along the second direction and the second guide surface 522a separates from the second transmission member 430, part of the second transmission member 430 is embedded in the groove 530, and the groove 530 and the second transmission member 430 are in a circumferential upper limit engagement with the connecting shaft 500.

[0152] When part of the second transmission component 430 is embedded in the slot 530, one of the multiple powder chambers 210 of the cylinder body 200 is opposite to the powder pressing plate 310. Thus, when the powder pressing assembly of this application has not yet been started and the powder pressing plate 310 is not aligned with the powder chamber 210, the second transmission component 430 can be driven to move into the slot 530, so that the powder pressing plate 310 is aligned with any one of the powder chambers 210, and then powder can be added to the powder chamber 210.

[0153] Since multiple second guide portions 522 are spaced apart circumferentially along the connecting shaft 500, correspondingly, multiple slots 530 are also distributed circumferentially along the connecting shaft 500. When the second transmission member 430 is embedded in the slot 530, the outer walls of the second transmission member 430 on both sides of the connecting shaft 500 in the circumferential direction can be respectively limited to the inner walls of the slots 530 on both sides of the connecting shaft 500 in the circumferential direction. In this way, when the second transmission member 430 continues to move in the second direction, the second transmission member 430 will restrict the rotation of the connecting shaft 500 to ensure that the powder chamber 210 of the cylinder 200 is positioned opposite to the powder pressing member 310. In this way, after the first drive assembly 400 drives the powder pressing member 310 to move, the powder pressing member 310 can move accurately toward the bottom wall of the powder chamber 210 to compress the powder in the powder chamber 210 into a powder cake structure.

[0154] When a portion of the second transmission component 430 is fitted into the slot 530 on the connecting shaft 500, there is a clearance between the second transmission component 430 and the slot 530, which is 0.1mm-0.5mm. The tolerance of the width of the slot 530 in the circumferential direction of the connecting shaft 500 is ±0.05mm, and correspondingly, the tolerance of the width of the portion of the second transmission component 430 fitted into the slot 530 is ±0.05mm.

[0155] Furthermore, in other embodiments, the powder processing device of this application may also be provided with a third driving component. The third driving component may be disposed on the base 100, and the third driving component may independently drive the cylinder 200 to rotate. Specifically, the third driving component may directly drive the connecting shaft 500 to rotate, thereby realizing the rotation of the cylinder 200.

[0156] In some implementations, reference Figures 8 to 9 As shown, the connecting shaft 500 of this application may be provided with a first shaft body 510 and a second shaft body 520, wherein the first shaft body 510 is disposed through the cylinder body 200, the second shaft body 520 is connected to the first drive assembly 400, and the first shaft body 510 and the second shaft body 520 are detachably connected.

[0157] Specifically, the second shaft 520 can be movably connected to the base 100, and the second shaft 520 is connected to the first drive assembly 400. When the first shaft 510 is connected to the second shaft 520, the first drive assembly 400 drives the second shaft 520 to rotate, which can drive the first shaft 510 to rotate, so that the cylinder 200 can rotate relative to the base 100.

[0158] When it is necessary to disassemble the cylinder body 200 from the base 100 to uniformly process the waste in the multiple powder chambers 210 of the cylinder body 200, the first shaft 510 and the second shaft 520 can be disassembled so that the cylinder body 200 can be separated from the first drive assembly 400, so that the cylinder body 200 can be easily disassembled.

[0159] In some implementations, reference Figures 8 to 9 As shown, the first shaft 510 in this application is movably connected to the cylinder 200, so that the first shaft 510 can move relative to the cylinder 200, wherein the axis of the first shaft 510 is consistent with the axis of the cylinder 200.

[0160] refer to Figure 9 As shown, when the first shaft 510 moves along the axial direction of the first shaft 510 and away from the direction of the second shaft 520, that is, along... Figure 9 When the first shaft 510 moves in the X direction, the end connecting the first shaft 510 and the second shaft 520 disengages from the second shaft 520, making the first shaft 510 and the second shaft 520 separable.

[0161] refer to Figure 8 As shown, when the first shaft 510 moves along its axial direction and toward the second shaft 520, that is... Figure 8 When the first shaft 510 moves in the opposite direction to the X direction, the end of the first shaft 510 connected to the second shaft 520 can move toward the second shaft 520, so that one end of the first shaft 510 is connected to the second shaft 520, and the first shaft 510 and the second shaft 520 can be connected.

[0162] Therefore, by applying a force along the circumferential direction to the first shaft 510, the first shaft 510 can be connected or separated from the second shaft 520.

[0163] In some embodiments, one of the first shaft 510 and the second shaft 520 of this application includes a male coupling head 511, and the other of the first shaft 510 and the second shaft 520 includes a female coupling head 523. The male coupling head 511 and the female coupling head 523 are detachably connected, so that the first shaft 510 and the second shaft 520 are detachably connected.

[0164] Specifically, the male coupling 511 can be located on the side of the first shaft 510 facing the second shaft 520, and the female coupling 523 can be located on the side of the second shaft 520 facing the first shaft 510. When the first shaft 510 moves towards the second shaft 520, the male coupling 511 can be inserted into the female coupling 523, connecting the first shaft 510 and the second shaft 520. When the first shaft 510 moves away from the second shaft 520, the male coupling 511 can be separated from the female coupling 523, separating the first shaft 510 from the second shaft 520.

[0165] By setting the male coupling 511 and the female coupling 523 to be connected, the connection between the first shaft 510 and the second shaft 520 is stable, so that the cylinder 200 can be driven to rotate accurately and stably.

[0166] In some implementations, reference Figure 11 As shown, the powder device of this application may also include a second drive assembly 600, which is disposed on the base 100 and is configured to drive the first shaft 510 to move toward or away from the second shaft 520, so that the first shaft 510 can be connected to or separated from the second shaft 520.

[0167] By setting the second drive component 600 to drive the first shaft 510 to move, it is more convenient to connect or separate the first shaft 510 from the second shaft 520.

[0168] In some implementations, reference Figures 12 to 15As shown, in order for the second drive assembly 600 of this application to drive the first shaft 510 to move toward the second shaft 520, the first shaft 510 and the second shaft 520 are connected. The second drive assembly 600 of this application may be provided with a crank-connecting rod 610, which has a rotating part 611 and a moving part 612, with the moving part 612 facing away from the end of the first shaft 510 opposite to the second shaft 520. The crank-connecting rod 610 can convert rotational motion into linear motion, and correspondingly, can convert rotational force into linear force.

[0169] Specifically, the base 100 may have a first limiting groove 131a, and the first end of the rotating part 611 is movably embedded in the first limiting groove 131a. The moving part 612 has a second limiting groove 612a, and the second end of the rotating part 611 is movably embedded in the second limiting groove 612a. The rotation center of the rotating part 611 is located between the first end and the second end of the rotating part 611. Figure 11 N. When the rotating part 611 rotates along the third circumferential direction, the first end of the rotating part 611 moves along the first limiting groove 131a, the second end of the rotating part 611 moves along the second limiting groove 612a, and the second end of the rotating part 611 pushes the moving part 612 to move toward the first shaft 510. When the rotating part 611 rotates along the fourth circumferential direction, the first end of the rotating part 611 moves in the opposite direction along the first limiting groove 131a, the second end of the rotating part 611 moves in the opposite direction along the second limiting groove 612a, and the second end of the rotating part 611 pushes the moving part 612 to move away from the first shaft 510.

[0170] In some embodiments, in this application, the center of the side of the moving part 612 opposite to the first shaft 510 coincides with the axis of the first shaft 510. Thus, when the moving part 612 contacts the first shaft 510, the center of force on the moving part 612 is located at the center of the side of the moving part 612 opposite to the first shaft 510. Figure 11 On the M-line. When the moving part 612 drives the first shaft 510 to move to dock with the second shaft 520, the center of the side of the moving part 612 opposite to the first shaft 510 is misaligned with the rotation center of the rotating part 611, so that the moving part 612 can achieve self-locking and can maintain abutment against the first shaft 510, so that the first shaft 510 and the second shaft 520 are docked.

[0171] refer to Figures 12 to 13As shown, when a force is applied to the rotating part 611 of the crank connecting rod 610, causing the rotating part 611 to rotate, the moving part 612 moves toward the first shaft 510, thereby driving the first shaft 510 to move toward the second shaft 520. This allows the male coupling 511 to move toward the female coupling 523, enabling the male coupling 511 to connect with the female coupling 523.

[0172] Specifically, the moving part 612 of the crank connecting rod 610 is opposite to the side of the first shaft 510 facing away from the second shaft 520, and the moving part 612 of the crank connecting rod 610 is not fixedly connected to the first shaft 510. When the first shaft 510 and the second shaft 520 are not yet connected, the moving part 612 has a certain distance from the side of the first shaft 510 facing away from the second shaft 520. After the rotating part 611 rotates in one direction and drives the moving part 612 to move, the moving part 612 can abut against the side of the first shaft 510 facing away from the second shaft 520 and push the first shaft 510 toward the second shaft 520.

[0173] In addition, refer to Figures 14 to 15 As shown, when the rotating part 611 rotates in another direction and drives the moving part 612 to move, the moving part 612 can move in the direction away from the first shaft 510, so that the moving part 612 does not contact the first shaft 510, making it convenient to disassemble the cylinder 200 from the base 100.

[0174] In some embodiments, to facilitate the movement of the first shaft 510 driven by the movable part 612, a positioning groove may be provided on the side of the first shaft 510 facing away from the second shaft 520. The movable part 612 can be moved such that a portion of the movable part 612 is embedded in the positioning groove, so that the movable part 612 and the first shaft 510 can remain stable. The maximum stroke of the movable part 612 is greater than the maximum distance between the first shaft 510 and the second shaft 520, that is, the movable part 612 can move away from the first shaft 510 to a distance from the first shaft 510, so that the movable part 612 can be more easily inserted into the positioning groove on the side of the first shaft 510 facing away from the second shaft 520.

[0175] Specifically, the maximum travel of the movable part 612 is 10cm, and the maximum travel of the first shaft 510 toward the second shaft 520 is 8cm.

[0176] In some implementations, reference Figures 16 to 18 As shown, the second drive assembly 600 of this application may further include an elastic element 620, which may be disposed on the cylinder body 200, and the first elastic element 620 is connected to the first shaft body 510. (See reference) Figures 17 to 18As shown, when the first shaft 510 moves toward the second shaft 520, the first shaft 510 can act on the elastic member 620, thereby causing the elastic member 620 to deform and generate an elastic force. At least part of the elastic force is directed in a direction away from the second shaft 520. Thus, when the moving part 612 no longer drives the first shaft 510 to move toward the second shaft 520, the elastic force of the elastic member 620 can drive the first shaft 510 to move in a direction away from the second shaft 520, allowing the first shaft 510 to separate from the second shaft 520.

[0177] Therefore, the second drive component 600 of this application can drive the first shaft 510 to move toward or away from the second shaft 520, so that the first shaft 510 and the second shaft 520 can be connected or separated.

[0178] In some implementations, reference Figures 17 to 18 As shown, the elastic element 620 of this application can be sleeved on the first shaft 510. One end of the elastic element 620 abuts against the cylinder 200, and the other end of the elastic element 620 abuts against the first shaft 510, so that the elastic element 620 can be fixed between the cylinder 200 and the first shaft 510.

[0179] Specifically, an annular stepped structure can be provided on the first shaft 510, and the elastic element 620 is a spring. One end of the spring abuts against the inner wall of the cavity in the cylinder 200 that houses the first shaft 510, and the other end of the elastic element 620 abuts against the stepped structure on the first shaft 510.

[0180] In some implementations, reference Figure 19 As shown, the base 100 of this application may be provided with a mounting cavity and a mounting port 120. The mounting cavity 110 communicates with the mounting port 120, and the cylinder body 200 is detachably disposed in the mounting cavity 110 through the mounting port 120. The shape and size of the mounting cavity 110 can match the shape and size of the cylinder body 200, so that the cylinder body 200 can remain stable when disposed in the mounting cavity 110, and the cylinder body 200 can be prevented from shaking.

[0181] When it is necessary to disassemble or install the cylinder block 200, the cylinder block 200 can be removed or placed through the mounting port 120 and the mounting cavity 110.

[0182] In some embodiments, the mounting port 120 of the base 100 of this application is oriented to intersect the axial direction of the connecting shaft 500, and may be specifically vertically oriented. In this way, the mounting port 120 is located on the side of the base 100, and the cylinder 200 can be removed and placed from the mounting cavity 110 of the base 100 by pushing and pulling the cylinder 200, making it convenient to remove and place the cylinder 200.

[0183] In some implementations, reference Figures 19 to 20As shown, the powder assembly of this application may also include a door 130, which is movably connected to the base 100. The door 130 can be driven to move to block the mounting port 120, so that the cylinder 200 can be sealed in the mounting cavity 110, thereby protecting the cylinder 200 and preventing foreign matter and impurities from entering the mounting cavity 110 through the mounting port 120 and contaminating the powder inside the cylinder 200. The door 130 can also be driven to move to a position offset from the mounting port 120, so that the door 130 can open the mounting port 120, allowing the cylinder 200 to be placed or removed from the mounting port 120.

[0184] The door body 130 can be connected to the rotating part 611 of the crank connecting rod 610. Specifically, the two sides of the door body 130 are clamping parts 131, which can be clamped to the base 100. The two clamping parts 131 can be connected to the two ends of the rotating part 611 respectively, making the connection between the door body 130 and the rotating part 611 more stable and reliable. The first limiting groove 131a is located on both sides of the door body 130 clamping parts 131 clamped to the base 100. The first limiting groove 131a is opened in the door body 130, and the first end of the rotating part 611 is movably embedded in the first limiting groove 131a of the door body 130. When the rotating part 611 is driven to rotate, causing the moving part 612 to move away from the first shaft 510, the rotating part 611 can correspondingly drive the door body 130 to move to a position that is misaligned with the mounting opening 120, so that the mounting opening 120 is opened. In this way, the cylinder body 200 can be removed from the mounting port 120 to clean the powder in the powder chamber 210 of the cylinder body 200.

[0185] After the powder in the powder chamber 210 of the cylinder 200 is cleaned, the cylinder 200 can be installed in the mounting cavity 110 through the mounting port 120. By driving the rotating part 611 to rotate in the fourth circumferential direction, the moving part 612 moves toward the first shaft 510. When the first shaft 510 is connected to the second shaft 520, the rotating part 611 can correspondingly drive the door 130 to move to be opposite to the mounting port 120, so that the door 130 closes the mounting port 120.
