Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for refractory powder pressing, specifically, it is a powder pressing and cleaning device. Background Technology

[0002] Cleaning the powder during the pressing process is a crucial step to ensure pressing quality and equipment cleanliness. Cleaning effectively reduces the impact of dust on the pressing process; for example, poor gas venting can lead to insufficient pressing force or reduced density of the pressed blank.

[0003] Currently, during the pressing and holding processes, cleaning is typically done manually with a brush or using a vacuum cleaner. However, the cleaning efficiency of conventional brush cleaning is low due to the size limitations of the brush. As for conventional vacuum cleaners, the nozzles are difficult to apply to the pressing mold for effective cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a powder pressing and cleaning device, which can be adapted to the shape of the pressing head and can efficiently clean the pressing gaps on the table during the pressing process.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A powder pressing and cleaning device, comprising:

[0007] The flexible hollow skeleton includes a first positioning end and a second positioning end, and the first positioning end and the second positioning end are connected by a number of deformation rods;

[0008] A soft covering film is used to cover all the deformation rods to form an air cavity. The two ends of the soft covering film are respectively connected to the first positioning end and the second positioning end.

[0009] A gripping mechanism is installed on the side of the first positioning end opposite to the air cavity. The gripping mechanism has an air passage that communicates with the air cavity and is connected to the suction end of the suction collector.

[0010] A sweeping tube is provided along the extension direction of the deformation rod and arranged on one of the deformation rods. The sweeping tube is connected to the air chamber. A brush is provided around the axis of the side of the sweeping tube opposite to the deformation rod.

[0011] Preferably, the first positioning end is a first annular plate, and the deformation rod is arranged around the axis of the first annular plate; the second positioning end is a second annular plate, and the deformation rod is arranged around the axis of the second annular plate; a hemispherical sealing plate is installed on the side of the second annular plate opposite to the deformation rod.

[0012] Furthermore, a reinforcing ring is constructed between the first positioning end and the second positioning end, and the two sides of the reinforcing ring are respectively connected to the ends of the deformation rod.

[0013] Furthermore, there are four deformation rods: a cylindrical rod at the bottom, a first strip plate in the middle, and a second strip plate at the top. The sweeping pipe is located on the cylindrical rod. The first strip plate has a rectangular longitudinal section and its vertical height is greater than its horizontal thickness. The second strip plate also has a rectangular longitudinal section and its vertical height is greater than its horizontal thickness.

[0014] Furthermore, the gripping mechanism includes a tapered portion connected to the first positioning end, the tapered end of the tapered portion being disposed away from the first positioning end, a grip rod being coaxially mounted on the tapered end of the tapered portion, and the air passage coaxially passing through the grip rod, the tapered portion, and the first positioning end and communicating with the air cavity.

[0015] Furthermore, the inner wall of the soft covering film is bonded to the deformation rod.

[0016] This utility model has the following beneficial effects during use:

[0017] During use, force is applied to the flexible hollow frame, causing the pen-shaped rod to change its shape. This allows the flexible hollow frame to match the external cross-sectional shape of the pressure head, enabling it to adhere to the outer wall of the pressure head during cleaning. Then, using a brush at the end of the sweeping tube, a small portion of the brush can reach into the gap between the side wall of the pressure head and the pressure groove, sweeping out some of the powder stuck in the gap. The swept powder is then collected by a suction collector. Furthermore, the brush also facilitates the cleaning of any spilled material remaining on the top surface of the worktable after feeding. The soft elasticity of the brush concentrates the material, which is then collected in the air chamber by the suction collector and collected through the air passage. This not only provides efficient and stable cleaning but also recovers scattered material, reducing waste. Attached Figure Description

[0031] Please refer to Figures 1 to 6 As shown, a powder pressing and cleaning device includes:

[0032] The flexible hollow frame includes a first positioning end 1 and a second positioning end 2, and the first positioning end 1 and the second positioning end 2 are connected by a plurality of deformation rods 3.

[0033] A soft covering film 5 is provided to cover all the deformation rods 3 to form an air cavity 4. The two ends of the soft covering film 5 are respectively connected to the first positioning end 1 and the second positioning end 2.

[0034] A gripping mechanism 6 is installed on the side of the first positioning end 1 opposite to the air cavity 4. The gripping mechanism 6 has an air passage 7 that communicates with the air cavity 4. The air passage 7 is connected to the suction end of the suction collector.

[0035] The sweeping pipe 8 is arranged along the extension direction of the deformation rod 3 and is arranged on one of the deformation rods 3. The sweeping pipe 8 is connected to the air chamber 4. A brush 9 is provided around the axis of the side of the sweeping pipe 8 opposite to the deformation rod 3.

[0036] In this way, during use, by applying force to the flexible hollow frame, the shape of the pen-shaped rod 3 is changed. This makes the shape of the flexible hollow frame match the external cross-sectional shape of the pressure head, allowing the flexible hollow frame to fit against the outer wall of the pressure head during cleaning. Then, using the brush 9 at the end of the sweeping pipe 8, a small portion of the brush 9 can reach into the gap between the side wall of the pressure head and the pressure groove while the flexible hollow frame is in contact with the outer wall of the pressure head, sweeping out some of the powder stuck in the gap. Then, under the action of the suction collector, the swept powder is cleaned and collected. Moreover, the action of the brush 9 also makes it easier to clean up the material that has been spilled on the top surface of the worktable due to feeding. Under the soft elasticity of the brush 9, the material is concentrated and then enters the air chamber 4 under the action of the suction collector, and is then collected in the suction collector through the air channel 7. In this way, not only can efficient and stable cleaning be achieved, but also scattered material can be recovered, reducing material waste.

[0037] Furthermore, the first positioning end 1 is a first annular plate, and the deformation rod 3 is arranged around the axis of the first annular plate. The second positioning end 2 is a second annular plate, and the deformation rod 3 is arranged around the axis of the second annular plate. A hemispherical sealing plate 10 is installed on the side of the second annular plate opposite to the deformation rod 3.

[0038] In this way, the arrangement of the first and second annular plates allows the deformation rod 3 to provide good and stable support for the soft covering membrane 5 when it is arranged around its axis. Moreover, the arrangement of the hemispherical sealing plate 10 allows the air cavity 4 to have better pressure-bearing capacity.

[0039] Furthermore, in order to improve the stability of the flexible hollow skeleton in a longer state, a reinforcing ring 11 is constructed between the first positioning end 1 and the second positioning end 2, and the two sides of the reinforcing ring 11 are respectively connected to the ends of the deformation rod 3.

[0040] In practical use, the flexible hollow skeleton generally swings back and forth on a horizontal plane. Therefore, in this embodiment, in order to increase the swing stability of the flexible skeleton in the horizontal direction and the rigidity of the flexible skeleton in the vertical direction, there are four deformation rods 3: a cylindrical rod 12 at the bottom, a first strip plate 13 in the middle, and a second strip plate 14 at the top. The sweeping pipe 8 is located on the cylindrical rod 12. The longitudinal section of the first strip plate 13 is rectangular, and the vertical height of the first strip plate 13 is greater than its horizontal thickness. The longitudinal section of the second strip plate 14 is rectangular, and the vertical height of the second strip plate 14 is greater than its horizontal thickness.

[0041] Furthermore, for ease of gripping during work, the gripping mechanism 6 includes a tapered portion 15 connected to the first positioning end 1. The tapered end of the tapered portion 15 is disposed away from the first positioning end 1. A grip rod 16 is coaxially mounted on the tapered end of the tapered portion 15. The air passage 7 coaxially passes through the grip rod 16, the tapered portion 15, and the first positioning end 1 and communicates with the air chamber 4.

[0042] Furthermore, the inner wall of the soft covering film 5 is bonded to the deformation rod 3.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
