The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other from other embodiments.

[0032] Embodiment 1

[0033] Refer to Figures 1-3, this embodiment provides a powder conveyor for preventing blockage and removing accumulation, including a conveying box 100. The conveying box 100 is the outer shell and internal fittings of the entire powder conveyor, but does not include the transmission components. It includes a box body 101. The box body 101 is the entire box shell part. On the inner wall of the top of the box body 101, first spring slides 101a are symmetrically provided. On the inner wall of the bottom of the box body 101, second spring slides 101b are symmetrically provided. Both types of spring slides are slides with springs inside, and there are other components connected to the internal springs, thus forming a situation where the components can be reset. Inside the box body 101, powder passing platforms 102 are symmetrically provided. The powder passing platform 102 is the part that the powder has to pass through at the front end of the outlet when it is about to leave the warehouse after the transportation is completed. Inside the box body 101, rotating shafts 101c are symmetrically provided. The rotating shafts 101c can rotate inside the box body 101 and are necessary parts for transportation. Inside the box body 101, spring sleeves 101d are symmetrically provided. Springs are provided inside the spring sleeves 101d. There are also cooperating components connected to the springs, and they are given the function of elastic reset;

[0034] Furthermore, the powder feeding mechanism 200 includes a driving gear 201 and rod wheels 202 coaxially fixed on the rotating shaft 101c. The driving gear 201 is a large gear fixed in the middle of the rotating shaft 101c, and the rod wheels 202 are two belt rod sleeve wheels fixed on both sides of the driving gear 201. On the left and right sides symmetrically arranged inside the box body 101, the driving gears 201 are meshed with a conveying track 203, thus connecting together to form a transmission. The powder is on the conveying track 203 to complete the entire conveying process, and then changes lanes and is discharged from the inside of the powder conveyor. A cleaning part 204 is rotatably connected to the powder passing platform 102. The cleaning part 204 is the main component to achieve the entire anti-blocking effect.

[0035] Embodiment 2

[0036] Referring to Figures 1-7 , this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: a discharge pipe 103 is fixedly connected to the bottom of the powder passing platform 102. The discharge pipe 103 is the outlet that the powder has to pass through after completing the lane-changing transportation. Three sides of the powder passing platform 102 are provided with baffle plates 102a, and only the inner side is not provided with a baffle plate 102a to avoid interfering with the operation of other components. A screen opening 102b is provided on the powder passing platform 102. The screen opening 102b will block the powder accumulated in blocks above the screen and not allow it to pass through. At the top of the screen opening 102b, a fixed bridge 102c is provided. A through hole 102c-1 is provided on the fixed bridge 102c to fix the main component, the cleaning part 204, so that the cleaning part 204 and the discharge pipe 103 form a cooperation.

[0037] Furthermore, the cleaning piece 204 is provided with a limiting rotating rod 204a rotatably connected to the through-hole 102c-1. The limiting rotating rod 204a is a miniature rotating shaft that can be clamped on the through-hole 102c-1. The top of the limiting rotating rod 204a is fixedly connected to a gear 204b, and the gear 204b is placed horizontally through a section of a column. The bottom is fixedly connected to a breaking piece 204c, and the breaking piece 204c is also placed horizontally through a section of a column. The distance of the column allows the breaking piece 204c to be placed on the surface of the drying net mouth 102b. When the powder accumulated in blocks stays on the screen mouth 102b, the breaking piece 204c will be driven by other components and start to rotate, breaking up the block powder on the net mouth, so that it can continue to flow down and complete the discharge.

[0038] Specifically, the bottom of the dispersing element 204c is fixedly connected to a material dispersing element 204d. This element is located within the discharge pipe 103 and comprises a filter shaft 204d-1, a filter plate 204d-2, an inclined sidewall scraper 204d-3, and a scraper 204d-4. The material dispersing element 204d is primarily responsible for removing accumulated powder at the discharge port, which can cause blockages and is the key to resolving these blockages.

[0039] Furthermore, the discharge pipe 103 includes a straight pipe portion 103a and a boss pipe portion 103b. The straight pipe portion 103a is a vertically downward pipe. Generally, sticky powder will stick to the inner wall, and accumulation is not common. The boss pipe portion 103b is a pipe type with a certain inclination angle from a small mouth to a large mouth. Generally, accumulation occurs here, and stickiness also exists. It is an important part of cleaning. Of course, if a certain protective device is provided for the straight pipe portion 103a in front, the difficulty of cleaning will be greatly reduced.

[0040] In detail, the four filter plates 204d-2 arranged on the circumference of the filter shaft 204d-1 are all closely attached to the inner wall of the straight pipe portion 103a on their outer sides. At the same time, the outer sides of the filter plates 204d-2 are arc-shaped, which can slide smoothly on the inner wall of the circular pipe and clean up the materials stuck on the inner wall. When the filter plates 204d-2 themselves rotate, they can also break up and granulate the lowered materials in multiple directions and angles without causing greater material pressure on the boss pipe portion 103b below, thereby reducing the difficulty of the work below.

[0041] Further, one side of the inclined side wall scraping rod 204d-3 is closely attached to the inner wall of the boss tube part 103b, so as to handle the problem of powder sticking in the boss tube part 103b. The scraping inclined side wall scraping rod 204d-3 is fixedly connected to the outer end of the filter screen plate 204d-2, which conforms to the inner wall structure of the boss tube part 103b. The scraping plate 204d-4 is fixed on the inclined side wall scraping rod 204d-3, which means that at the lowermost end of the boss tube part 103b, a most comprehensive and complete cleaning area is given. The scraping plate 204d-4 is an arc-shaped metal iron sheet, and the four annularly arranged scraping plates 204d-4 can clean the sticking on the inner wall and the accumulation at the concave corners at the outlet of the boss tube 103b with high frequency and high coverage. For the powder flowing down in the middle, it has been granulated multiple times by the upper filter screen plate 204d-2 and the dispersing part 204c. The outer side of the scraping plate 204d-4 is also closely attached to the inner wall of the boss tube part 103b. Inclined surfaces M are provided on both side surfaces of the inclined side wall scraping rod 204d-3 and the scraping plate 204d-4. This design of the inclined surface is more convenient for the two material-unclogging components to clean the sticking on the inner wall, and the tip of the inclined angle is more convenient for shoveling the materials.

[0042] Embodiment 3

[0043] Referring to Figures 1-9 , this is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: three driving rods 202a are evenly arranged in a ring on the rod wheel 202. A transverse moving member 205 is slidably connected to the first spring slide rail 101a. The transverse moving member 205 can slide within a small range inside the box body 101. As can be seen from the drawing part, the first spring slide rail 101a is designed with two slideways as a group and two groups are symmetrically arranged. Therefore, the transverse moving member 205 is also composed of two slide columns and a cross bar. The two slide columns are respectively slidably connected to the first spring slide rail 101a and fixedly connected to the springs inside it. A telescopic sleeve column 206 is slidably connected to the second spring slide rail 101b. The telescopic sleeve 206 is fixedly connected to the spring inside the second spring slide rail 101b to complete the reset in the horizontal direction. At the same time, a spring is also provided inside the telescopic sleeve column 206 to ensure the reset in the vertical direction. A lower pressing plate 207 is elastically connected inside the telescopic spring sleeve 101d. The default position of the lower pressing plate 207 is directly above the telescopic sleeve column 206.

[0044] Inside the telescopic sleeve column 206, there is a pulley column 206a elastically connected. Since both the telescopic sleeve column 206 and the second spring slide rail 101b have springs to assist in their reset, the pulley column 206a has a certain reset ability in both the horizontal and vertical positions. And the pulley column 206a is connected to the spring inside the telescopic sleeve column 206, so it can be raised or lowered inside the telescopic sleeve column 206. At the top of the pulley column 206a, there is a pulley 206a-1, and on the side, there is a material shoveling elastic piece 206a-2. The material shoveling elastic piece 206a-2 is a metal thin sheet with a certain elasticity and has a certain corrosion resistance. It is responsible for shoveling the scattered powder on the bottom plate of the box body 101 into the area of the powder passing platform 102. It can be automatically sucked into the entrance of the powder passing platform 102 by relying on the pressure difference formed by the entrance of the powder passing platform 102 and the rotation of the cleaning part 204, and then enter the discharge port, completing the self-cleaning of the powder inside the box body 101;

[0045] As mentioned before, the position of the lower pressing plate 207 is directly above the telescopic sleeve column 206. At the bottom of the lower pressing plate 207, there are convex corner blocks 207a. On the two inclined surfaces of the convex corner blocks 207a, there are sliding grooves 207a-1. The pulley 206a-1 is slidably connected to the sliding grooves 207a-1. The pulley 206a-1 matches the configuration of the telescopic sleeve column 206, in pairs. So the pulley column 206a and the transverse moving part 205 are also fixed in pairs and are respectively connected to a telescopic sleeve column 206.

[0046] Furthermore, the top of the material shoveling elastic piece 206a-2 is squeezed by the convex corner block 207a, and the bottom is squeezed by the inner wall of the box body 101. At the same time, the pulley 206a-1 slides on the sliding groove 207a-1, which means that when the lower pressing plate 207 presses down, the two symmetric groups of pulley columns 206a will move horizontally in a direction tending to separate. At the same time, as can be seen from the attached drawing, the direction in which the material shoveling elastic piece 206a-2 is oppressed can shovel the ground powder in the separating direction as described above. Exactly the only side of the powder passing platform 102 without the baffle 102a is the shoveling facing surface of the material shoveling elastic piece 206a-2;

[0047] Specifically, the width of the material shoveling elastic piece 206a-2 is the same as the inner width of the box body 101, which can ensure that the material shoveling elastic piece 206a-2 can completely cover the bottom plate of the entire box body 101 for shoveling and cleaning work, and also isolate the area where the powder exists, allowing it to only move within the cleaning range and not cross the material shoveling elastic piece 206a-2;

[0048] Furthermore, the driving rod 202a can contact the transverse moving member 205 and the lower pressing plate 207. This step is the basis for the transmission of the entire internal component. Since the driving rod 202a is fixed to the rod wheel 202, as long as the powder feeder is operating and the rotating shaft 101c is rotating, the driving rod 202a will definitely rotate following the rotating shaft. When the driving rod 202a contacts the transverse moving member 205, the transverse moving member 205 will be pushed away by the driving rod 202a. Also, due to the annular design feature of the driving rod 202a, the moving trajectory of the transverse moving member 205 is reciprocating. A toothed plate 205a is provided on the transverse moving member 205 and meshes with the gear 204b. In this way, this reciprocating motion determined by the driving rod 202a will be transmitted to the entire cleaning member 204, causing the cleaning member 204 to also perform a reciprocating rotation. While the entire powder feeder is working, synchronous cleaning, removal of accumulation, and prevention of blockage are carried out.

[0049] Furthermore, the driving rod 202a can contact the lower pressing plate 207. Similar to the transverse moving member 205, due to the annular design feature of the driving rod 202a, the lower pressing plate 207 is regularly and reciprocally pressed down by the driving rod 202a, constantly performing the above-mentioned action of the shoveling spring piece 206a - 2 shoveling the materials scattered from the bottom plate of the box body 101, thereby completing the second self-cleaning action. The problems of blockage and accumulation at the powder passing table 102 and the cleaning member 204 are solved. The lower pressing plate 207 and the shoveling spring piece 206a - 2 solve the problem of scattered material accumulation inside the box body 101, and all actions are carried out synchronously with the transportation automatically, greatly improving the working efficiency of the entire powder feeder and also providing a complete self-cleaning technology. An inlet pipe 101e is provided at the top of the box body 101. Materials enter the box body 101 from here and come above the conveying track 203, and finally fall onto the powder passing table 102 and are discharged from the discharge pipe 103.

[0050] It should be noted that the rotation of the two driving rods 202a is synchronous, not mirror-image. Therefore, the cleaning work on the left and right sides is not completely synchronous, but it does not affect the overall cleaning process. The law of the lower pressing of the lower pressing plate below is not simply up and down, but rather short-frequency up and down floating accompanied by high-frequency up and down jitter. Such an operating law is more suitable for repeatedly shoveling the scattered materials at the bottom of the box body 101, piling them up in the area of the powder passing table 102, and then being sucked into the discharge pipe 103. In the figure, the powder feeder is not covered. A sealing cover can be set in the front to put the powder feeder into use.

[0051] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without materially departing from the novel teachings and advantages of the subject matter described in this application (e.g., changes in the dimensions, scales, structures, shapes and proportions of various elements, as well as parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, colors, orientations, etc.). For example, elements shown as integrally formed may be composed of multiple parts or elements, the positions of the elements may be inverted or otherwise changed, and the nature, number or position of discrete elements may be altered or changed.
