Description

Technical Field

[0001] This invention relates to the field of powder transfer technology, and more specifically to a powder transfer device. Background Technology

[0002] During the powder transfer process, transfer containers are usually required. When the powder is transported into the transfer container, it will scatter everywhere, which not only pollutes the working environment, but also results in the loss of some powder, thus causing waste.

[0003] Chinese patent CN218318327U discloses a powder grinding and storage transfer device. In use, the powder is added into the powder cylinder through the inlet, and then the powder cover is screwed on. The base is installed on the conveyor frame of the production line. The powder cylinder inserts the barb into the groove corresponding to the slot. The powder cylinder is rotated so that the barb is inserted into the barb insertion hole, and the powder cylinder is fastened to the base. The powder cylinder is conveyed to the storage location by the production line conveyor frame.

[0004] However, during the process of adding powder into the powder cylinder, due to the height difference between the powder feeding position and the bottom of the powder cylinder, the powder will scatter in all directions. In addition, when the powder in the powder cylinder is finished, the powder in the powder cylinder will bulge upwards, so it needs to be manually leveled, which is not convenient to operate. Summary of the Invention

[0005] This invention provides a powder transfer device, which aims to solve the problems in related technologies where powder scatters everywhere and powder bulges upwards inside the powder cylinder during the process of adding powder into the powder cylinder.

[0006] A powder transfer device includes a barrel and a shell. The top of the barrel has an opening. A shaft is coaxially fixed inside the barrel. A sleeve is coaxially rotatably mounted on the outer periphery of the shaft. A support plate is coaxially slidably mounted on the outer periphery of the sleeve. The support plate is connected to the bottom of the barrel via a first elastic element. A mating groove for sliding engagement with the support plate is formed on the outer periphery of the sleeve. A drive member is coaxially fixed at the lower end of the sleeve. The drive member is connected to the shaft via a second elastic element. A mating rod is slidably mounted on the shaft along its axial direction. A mating block is slidably mounted on the lower end of the shaft along its radial direction. The shell is fixedly mounted on the top of the sleeve. The support plate is located below the shell. A slide rod is slidably mounted on the shell along its length extension direction. The slide rod is connected to the shell via a fourth elastic element. When the support plate moves downward along the axial direction of the shaft, it causes the sleeve to rotate, allowing the mating block to slide back and forth along the radial direction of the shaft, allowing the mating rod to move up and down, thereby allowing the slide rod to slide back and forth along the length extension direction of the shell.

[0007] Preferably, a mating hole is provided on the bearing plate to mate with the outer peripheral wall of the sleeve, and a driving block that mates with the mating groove is fixedly provided inside the mating hole. The mating groove includes an upper annular groove, a spiral groove, a vertical groove and a lower annular groove that are sequentially opened from top to bottom and connected to each other on the outer peripheral wall of the sleeve. The first end and the end of the spiral groove are both located in the length extension direction of the vertical groove.

[0008] Preferably, a continuous protrusion is provided on the inner side of the driving member along its circumference. The protrusion is vertically arranged and a groove is provided between two adjacent protrusions. The second elastic member is installed on the outer circumference of the shaft. The upper end of the second elastic member is fixedly connected to the driving member, and the lower end of the second elastic member is fixedly connected to the shaft.

[0009] Preferably, the mating block is located inside the driving member, the mating block is connected to the barrel body through a third elastic member, the end of the mating block away from the third elastic member has a stop portion that cooperates with the protrusion, the lower end of the mating rod has a first inclined surface, and the upper end of the mating block has a second inclined surface that cooperates with the first inclined surface.

[0010] Preferably, a plurality of striking blocks are provided at intervals along the length extension direction at the lower end of the housing. The striking blocks are connected to the housing through a fifth elastic element. When the slide rod slides back and forth along the length extension direction of the housing, it can drive the striking blocks to move back and forth in the vertical direction.

[0011] Preferably, the upper end of the mating rod has a first tapered portion, the end of the slide rod near the shaft extends into the shaft and is slidably connected to the shaft, and the end of the slide rod near the shaft has a third inclined surface that mates with the first tapered portion, the first tapered portion being located below the third inclined surface.

[0012] Preferably, the upper end of the striking block has a second conical portion, and the lower end of the slide bar has a conical groove that mates with the second conical portion.

[0013] Preferably, a cover is provided at the top opening of the barrel, and a receiving groove for accommodating the shell is provided at the lower end of the cover.

[0014] Preferably, the housing extends radially along the sleeve, and the end of the housing away from the sleeve is close to the inner wall of the barrel.

[0015] Preferably, the first elastic element is located on the outer periphery of the sleeve, and the upper and lower ends of the first elastic element are fixedly connected to the lower end face of the bearing plate and the bottom of the barrel body, respectively.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0017] 1. As the powder gradually falls onto the support plate, the first elastic element is gradually compressed, and the support plate gradually descends. During this process, the drive element rotates with the sleeve, and the second elastic element continuously stores force. When the support plate moves to the bottom, the second elastic element releases the stored force, causing the drive element and the sleeve to reverse. During this process, the mating rod can move up and down along the axis of the shaft, and the housing rotates with the sleeve. The sliding rod can intermittently tap the inner wall of the barrel, thereby preventing the powder from accumulating on the inner wall of the barrel. Moreover, the housing can flatten the powder inside the barrel.

[0018] 2. When the powder is poured out of the barrel, as the bearing plate moves to the top, the second elastic element releases the stored force. During this process, the mating rod can move up and down along the axis of the shaft, and the housing will rotate with the sleeve. The sliding rod can intermittently tap the inner wall of the barrel, which helps the powder on the inner wall of the barrel to flow out smoothly. Multiple tapping blocks can move up and down simultaneously, which can tap the upper surface of the bearing plate to clean the powder adhering to the upper surface of the bearing plate.

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1-9 As shown, a powder transfer device includes a barrel 10 with an opening at the top. A shaft 11 is coaxially fixed inside the barrel 10. A sleeve 12 is coaxially rotatably mounted on the outer periphery of the shaft 11. A bearing plate 13 is coaxially slidably mounted on the outer periphery of the sleeve 12. The bearing plate 13 can move up and down along the axial direction of the sleeve 12. A first elastic element 14, specifically a first spring, is mounted on the outer periphery of the sleeve 12. The upper and lower ends of the first elastic element 14 are fixedly connected to the lower end face of the bearing plate 13 and the bottom of the barrel 10, respectively.

[0031] A fitting groove is formed on the outer peripheral wall of the sleeve 12. The fitting groove includes an upper annular groove 121, a spiral groove 122, a vertical groove 123, and a lower annular groove 124, which are sequentially formed from top to bottom and connected to each other on the outer peripheral wall of the sleeve 12. The upper annular groove 121 is close to the top of the sleeve 12, and the lower annular groove 124 is close to the bottom of the sleeve 12. It can be understood that the first end of the spiral groove 122 is connected to the upper annular groove 121, the last end of the spiral groove 122 is connected to the upper end of the vertical groove 123, and the last end of the vertical groove 123 is connected to the lower annular groove 124. It should be noted that the first and last ends of the spiral groove 122 are both located in the length extension direction of the vertical groove 123. In this embodiment, the spiral groove 122... The number of turns is two; a mating hole is provided on the bearing plate 13 to mate with the outer peripheral wall of the sleeve 12, and a drive block 131 that mates with the mating groove is fixedly provided on the inner side of the mating hole. A drive member 15 is coaxially fixedly installed at the lower end of the sleeve 12. A continuous protrusion 151 is provided on the inner side of the drive member 15 along its circumference. The protrusion 151 is vertically arranged and there is a groove between two adjacent protrusions 151. A second elastic member 152 is installed on the inner side of the drive member 15. The second elastic member 152 is specifically a torsion spring. The second elastic member 152 is installed on the outer peripheral side of the shaft 11. The upper end of the second elastic member 152 is fixedly connected to the drive member 15, and the lower end of the second elastic member 152 is fixedly connected to the shaft 11.

[0032] A mating block 16 is slidably mounted radially at the lower end of the shaft 11. The mating block 16 is located inside the drive member 15. The mating block 16 is connected to the barrel 10 via a third elastic member 161, which is specifically a third spring. Specifically, a mounting plate 101 is fixedly installed at the bottom inside the barrel 10. Both ends of the third elastic member 161 are fixedly connected to the mounting plate 101 and the mating block 16, respectively. The end of the mating block 16 away from the third elastic member 161 has a stop portion 162 that mates with the protrusion 151. A mating rod 111 is slidably mounted axially on the inner side of the shaft 11. The lower end of 11 has a first inclined surface, and the upper end of the mating block 16 has a second inclined surface that mates with the first inclined surface. When the stop part 162 abuts against the protrusion 151, the third elastic member 161 is compressed, and the mating block 16 can move toward the mounting plate 101 so that the second inclined surface abuts against the first inclined surface, thereby allowing the mating rod 111 to move upward. When the stop part 162 enters the groove, the mating block 16 can move away from the mounting plate 101 so that the second inclined surface disengages from the stop with the first inclined surface. At this time, the mating rod 111 can move downward under the action of gravity.

[0033] A housing 17 is fixedly installed on the outer periphery of the top of the sleeve 12. The housing 17 extends radially along the sleeve 12, with the end of the housing 17 away from the sleeve 12 close to the inner wall of the barrel 10. The bearing plate 13 is located below the housing 17. A slide rod 171 is slidably installed inside the housing 17 along its length. The slide rod 171 is connected to the housing 17 via a fourth elastic element 172, which is specifically a fourth spring. Both ends of the fourth elastic element 172 are fixedly connected to the slide rod 171 and the housing 17, respectively. Multiple striking blocks 173 are spaced apart at the lower end of the housing 17 along its length. Block 173 can move vertically. The striking block 173 is connected to the housing 17 via the fifth elastic element 174, which is specifically the fifth spring. It should be noted that the upper end of the mating rod 111 has a first tapered portion. The end of the sliding rod 171 near the shaft 11 extends into the shaft 11 and is slidably connected to the shaft 11. The end of the sliding rod 171 near the shaft 11 has a third inclined surface that mates with the first tapered portion, and the first tapered portion is located below the third inclined surface. The upper end of the striking block 173 has a second tapered portion, and a tapered groove that mates with the second tapered portion is provided at the lower end of the sliding rod 171.

[0034] Thus, when the mating rod 111 moves upward, the first conical part can stop against the third inclined surface, so that the sliding rod 171 moves towards the inner wall of the barrel 10 to strike the inner wall of the barrel 10. During this process, with the cooperation of the second conical part and the conical groove, the sliding rod 171 can also drive multiple striking blocks 173 to slide downward simultaneously, thereby striking the upper end surface of the bearing plate 13. When the mating rod 111 moves downward, with the assistance of the fourth elastic element 172 and the fifth elastic element 174, the sliding rod 171 can move away from the inner wall of the barrel 10, and the striking blocks 173 can slide upward to reset.

[0035] A cover 18 is provided at the top opening of the barrel 10, and a receiving groove for accommodating the shell 17 is provided at the lower end of the cover 18.

[0036] Specific working principle: (See reference) Figures 1-9When there is no powder in the barrel 10, the upper end face of the support plate 13 contacts the lower end face of the shell 17, and the drive block 131 is located in the upper annular groove 121 and corresponds to the first end of the spiral groove 122. When powder needs to be added to the barrel 10, first open the cover 18, then align the external feed pipe with the top opening of the barrel 10. As the powder gradually falls onto the support plate 13, the first elastic element 14 is gradually compressed, and the support plate 13 gradually descends. During this process, the drive block 131 enters the spiral groove 122, causing the sleeve 12 to rotate, while the support plate 13 does not rotate. The drive element 15 rotates with the sleeve 12, and the second elastic element 152 continuously stores force. The mating block 16 moves along... The radial reciprocating sliding of the shaft 11 can be understood as follows: the sleeve 12 will rotate two revolutions until the drive block 131 enters the vertical groove 123 downwards. At this time, the second elastic element 152 stops storing force. When the drive block 131 enters the lower annular groove 124 downwards, the addition of powder to the barrel 10 stops. At this time, the second elastic element 152 will release the stored force, so that the drive element 15 and the sleeve 12 will reverse two revolutions. During this process, the mating rod 111 can move up and down along the axial direction of the shaft 11, and the housing 17 will rotate with the sleeve 12. The sliding rod 171 can intermittently tap the inner wall of the barrel 10, thereby preventing the powder from accumulating on the inner wall of the barrel 10. Moreover, the housing 17 can flatten the powder in the barrel 10.

[0037] Understandably, when the second elastic element 152 releases all the stored force, the drive block 131 will move to the position where the lower annular groove 124 and the vertical groove 123 are connected. In addition, during the descent of the support plate 13, the height of the top surface of the powder on the support plate 13 from the feed pipe remains constant, thereby preventing the powder from scattering everywhere.

[0038] When it is necessary to pour out the powder from the barrel 10, as the barrel 10 tilts, the powder will continuously flow out. With the assistance of the first elastic element 14, the bearing plate 13 will continuously approach the top opening of the barrel 10. During this process, the drive block 131 will move upward through the spiral groove 122 and cause the sleeve 12 to rotate two revolutions. At the same time, the second elastic element 152 will continuously store force. When the drive block 131 moves upward into the upper annular groove 121, the second elastic element 152 will release the stored force, thereby causing the drive block 131 to move upward through the spiral groove 122 and rotate two revolutions. The moving part 15 and the sleeve 12 rotate two turns. During this process, the mating rod 111 can move up and down along the axial direction of the shaft 11, and the housing 17 will rotate with the sleeve 12. The sliding rod 171 can intermittently tap the inner wall of the barrel 10, which is conducive to the smooth flow of powder on the inner wall of the barrel 10. Moreover, multiple tapping blocks 173 can move up and down simultaneously, which can tap the upper end face of the bearing plate 13, so as to clean the powder adhering to the upper end face of the bearing plate 13.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
