Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of binder jetting equipment, in particular to a powder cleaning system of a binder jetting equipment. BACKGROUND

[0002] In the binder jetting additive manufacturing process, the binder jetting equipment forms a shaped part by selectively jetting a binder to the surface of a powder bed, and the unbound powder remaining on the periphery of the shaped part and inside the equipment accumulates on the key components such as the guide rail and the nozzle of the equipment, causing movement to be stuck, the nozzle to be blocked, and the service life of the equipment to be shortened. At the same time, if some special powder is left for a long time, it may affect the performance of subsequent use due to moisture and oxidation, so efficient powder cleaning of the binder jetting equipment is a key link to ensure the continuous and stable operation of additive manufacturing.

[0003] However, the traditional powder cleaning device of the binder jetting equipment mostly uses a single powder suction pipe or a fixed powder suction structure. The single powder suction pipe needs to be repeatedly moved to cover the internal area of the equipment, resulting in low efficiency when cleaning a large area. Although multiple fixed powder suction structures can be used to clean a large area, it is difficult to completely remove the stubbornly remaining powder in the local area due to insufficient local suction force caused by the large suction range. In addition, although some devices are equipped with a powder blowing structure, the gas blowing pipeline is mostly fixedly arranged, and the blowing direction and range cannot be flexibly adjusted, which may cause the powder to be blown away and not be timely sucked away, resulting in secondary accumulation. Moreover, the powder blowing and suction coordination is poor, it is difficult to achieve uniform cleaning in a large range, and it cannot meet the requirements of the binder jetting equipment in terms of cleaning efficiency, flexibility and thoroughness.

[0004] In view of the above problems, the present application provides a powder cleaning system of a binder jetting equipment. SUMMARY

[0005] The purpose of the present application is to solve the problems of the traditional powder cleaning device of the binder jetting equipment, which mostly uses a single powder suction pipe or a fixed powder suction structure. The single powder suction pipe needs to be repeatedly moved to cover the internal area of the equipment, resulting in low efficiency when cleaning a large area. Although multiple fixed powder suction structures can be used to clean a large area, it is difficult to completely remove the stubbornly remaining powder in the local area due to insufficient local suction force caused by the large suction range. In addition, although some devices are equipped with a powder blowing structure, the gas blowing pipeline is mostly fixedly arranged, and the blowing direction and range cannot be flexibly adjusted, which may cause the powder to be blown away and not be timely sucked away, resulting in secondary accumulation. Moreover, the powder blowing and suction coordination is poor, it is difficult to achieve uniform cleaning in a large range, and it cannot meet the requirements of the binder jetting equipment in terms of cleaning efficiency, flexibility and thoroughness.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme: A powder cleaning system of a binder jetting equipment, comprising a housing, wherein a powder cleaning mechanism is arranged in the housing. The powder cleaning mechanism includes a linear motion component, on which a rotary air blowing component is provided. The second gear of the rotary air blowing component meshes with a rack.

Multiple rotary air intake components are provided below the air intake main pipe. The linear motion component has an intake rotation control component and a valve single control component on both sides of the threaded seat. The first tooth of the intake rotation control component can mesh with the first gear of the rotating intake component through displacement, so as to realize the rotation of the intake pipe. The valve single control component can mesh downward with the toothed valve of the rotating intake component to open a single intake pipe. The toothed valves arranged in the same row can mesh with the toothed segment of the valve master control component, so as to synchronously control the opening and closing of multiple intake pipes.

[0007] Preferably, the housing is provided with an industrial fan, a dust collection device, a recycling bin, and a cyclone separator. The airflow outlet of the cyclone separator is connected to the industrial fan, the cyclone separator is connected to the main air intake pipe through the dust collection device, and the bottom of the cyclone separator is connected to the recycling bin.

[0008] Preferably, the rotary air intake assembly includes a connector that is connected to the main air intake pipe, and the connector is provided with a toothed valve.

[0009] Preferably, the lower part of the connector is connected to an inclined powder suction head, the powder suction head is rotatably mounted on the connector via a bearing, and a first gear is installed on the powder suction head.

[0010] Preferably, the valve master control assembly includes two fixed blocks, which are respectively fixedly connected to two fixed plates. A first electric push rod and a first telescopic rod are respectively installed on the two fixed blocks. A movable strip is fixedly connected between the first electric push rod and the first telescopic rod, and multiple toothed segments are provided below the movable strip.

[0011] Preferably, the linear motion assembly includes two fixed plates, which are fixedly connected to the housing. A motor is provided on one side of each fixed plate, and a screw is fixedly connected to the output shaft of the motor. A threaded seat is threaded onto the screw.

[0012] Preferably, the threaded seat is slidably connected to two guide rods, and the two ends of the two guide rods are respectively fixedly connected to two fixed plates.

[0013] Preferably, the valve single-control assembly includes a fixing frame, which is fixedly connected above the threaded seat. A third electric push rod is mounted on the fixing frame, and a second toothed rod is fixedly connected to one end of the third electric push rod.

[0014] Preferably, the intake rotation control assembly includes a bracket, which is fixedly connected to a threaded seat. A second electric push rod and a second telescopic rod are mounted on the bracket. A connecting frame is fixedly connected between the second electric push rod and the second telescopic rod. A first toothed rod is fixedly connected to the connecting frame.

[0015] Preferably, the rotary air blowing assembly includes an air blowing device, which is mounted on a threaded seat. The air outlet of the air blowing device is connected to a splitter head.

[0016] Compared with the prior art, the present invention provides a powder removal system for an adhesive spraying device, which has the following beneficial effects: The powder removal system of this adhesive spraying equipment can achieve the following: the main valve control component can keep all the rotary air intake components open, and multiple powder suction heads are distributed in an array to achieve large-area powder suction. Secondly, the individual valve control component can open multiple or a single powder suction head in a local area, thereby concentrating the negative pressure on the target area to quickly remove stubborn residual powder. The rotary air intake control component can also rotate the powder suction head, allowing the powder suction head to dynamically adjust its position and achieve uniform powder suction. Furthermore, the flexible switching and dynamic adjustment of the powder suction head significantly improves the powder removal efficiency and targeting. The powder cleaning system of this adhesive spraying equipment can drive the rotary air blowing component to perform linear reciprocating motion through the linear motion component, increasing the powder blowing area. The displacement of the rotary air blowing component can be driven by the rack and pinion, so that the rotation of the jet head can evenly blow away the accumulated powder and avoid cleaning dead corners caused by powder agglomeration. The powder cleaning system of this adhesive spraying equipment uses a linear motion component to drive a rotary air blowing component in reciprocating motion. During the motion, it works with a rack and pinion to perform comprehensive powder blowing. When blowing powder by displacement, the air intake rotation control component drives the rotary air intake component to rotate, enabling precise powder suction during the uniform powder blowing process. When blowing powder in a localized area, the local air intake pipe is opened by a valve single-control component, allowing the rotary air intake component to continue rotating for precise powder suction. This achieves a combination of large-area uniform powder cleaning and localized precise cleaning. The mechanical following mechanism expands the dynamic powder suction range and can quickly complete synchronous removal, ensuring both the efficiency and uniformity of powder cleaning while thoroughly removing residual powder. This provides a strong guarantee for the accuracy of subsequent printing processes and the lifespan of the equipment. Attached Figure Description

[0021] Example 1: Refer to Figures 1-9 A powder cleaning system for an adhesive spraying device includes a housing 100, in which an industrial fan 300, a dust collection device 500, a recycling bin 600, and a cyclone separator 400 are disposed. The airflow outlet of the cyclone separator 400 is connected to the industrial fan 300. Through the cooperation of the industrial fan 300 and the cyclone separator 400, the high-speed rotating airflow forms centrifugal force, thereby successfully separating the powder, which is then recycled through the recycling bin 600. The cyclone separator 400 is connected to the air intake pipe 204 through the dust collection device 500, which allows the powder to be smoothly fed into the cyclone separator 400 for easy powder cleaning. The bottom of the cyclone separator 400 is connected to the recycling bin 600. A powder cleaning mechanism 200 is installed in the housing 100. The powder cleaning mechanism 200 includes a linear motion component 201, on which a rotary air blowing component 206 is mounted. The rotary air intake component 205 includes a connector 2051, which is connected to the main air intake pipe 204. A toothed valve 2052 is mounted on the connector 2051, allowing control of its opening and closing. The lower part of the connector 2051 is connected to an inclined powder suction head 2054. The inclined arrangement of the powder suction head 2054 increases the uniformity of subsequent rotary powder suction. The powder suction head 2054 is rotatably mounted via bearings. On the connector 2051, the powder suction head 2054 can be kept rotating stably by the bearing. The powder suction head 2054 is equipped with a first gear 2053, which is driven by the first rack 2075, so that the powder suction head 2054 can rotate to achieve uniform powder suction. The second gear 2064 of the rotating air blowing assembly 206 meshes with the rack 202. The rack 202 is installed on the air intake pipe 204. The air intake pipe 204 is installed on the two fixed plates 2011 of the linear motion assembly 201. Multiple rotating air intake assemblies 205 are arranged below the air intake pipe 204. The linear motion assembly 201 has an intake rotation control assembly 207 and a valve single-control assembly 208 on both sides of the threaded seat 2014. The valve single-control assembly 208 includes a fixing frame 2081, which is fixedly connected to the top of the threaded seat 2014. A third electric push rod 2082 is mounted on the fixing frame 2081. A second gear 2083 is fixedly connected to one end of the third electric push rod 2082. The third electric push rod 2082 can control the transmission between the second gear 2083 and the gear valve 2052, thereby allowing for individual control of the opening and closing of the powder suction head 2054. This facilitates localized powder cleaning operations, and the partial opening of the powder suction head 2054 enables rapid... To quickly remove powder and improve the powder removal effect, the air intake rotation control component 207 includes a bracket 2071, which is fixedly connected to the threaded seat 2014. A second electric push rod 2072 and a second telescopic rod 2073 are mounted on the bracket 2071. The telescopic nature of the second telescopic rod 2073 allows the first gear 2075 to maintain stable movement. A connecting frame 2074 is fixedly connected between the second electric push rod 2072 and the second telescopic rod 2073. The first gear 2075 is fixedly connected to the connecting frame 2074. The second electric push rod 2072 controls the movement of the connecting frame 2074, causing the first gear 2075 to engage with the first gear 2053. Reciprocating transmission controls the powder suction head 2054 to rotate and suction powder. The first gear 2075 of the air intake rotation control component 207 can mesh with the first gear 2053 of the rotating air intake component 205 through displacement, realizing the rotation of the air intake pipe. The valve single control component 208 can mesh downward with the toothed valve 2052 of the rotating air intake component 205, realizing the opening of a single air intake pipe. The toothed valves 2052 arranged in the same row can mesh with the toothed segment 2035 of the valve master control component 203, thereby synchronously controlling the opening and closing of multiple air intake pipes. The valve master control component 203 includes two fixed blocks 2032, which are respectively fixedly connected to two On a fixed plate 2011, a first electric push rod 2031 and a first telescopic rod 2034 are respectively installed on two fixed blocks 2032. The telescopic nature of the first telescopic rod 2034 allows the movable bar 2033 to maintain stable extension and retraction. The movable bar 2033 is fixedly connected between the first electric push rod 2031 and the first telescopic rod 2034. Multiple toothed segments 2035 are provided below the movable bar 2033. The first electric push rod 2031 controls the extension and retraction of the movable bar 2033, so that the toothed segments 2035 can engage with the corresponding toothed valves 2052, thereby synchronously opening or closing all powder suction heads 2054, which facilitates the switching of powder suction heads 2054.

[0022] In this embodiment: the first electric push rod 2031 controls the movement of the movable bar 2033, which drives the toothed segment 2035 and the toothed valve 2052 to open all the connectors 2051. Since the multiple powder suction heads 2054 are arranged in an array, large-area powder suction can be achieved. Secondly, the third electric push rod 2082 drives the second toothed bar 2083 and the toothed valve 2052 to drive, and the linear motion component 201 is used for position adjustment. This allows multiple or a single powder suction head 2054 to be opened individually, so that the negative pressure can be concentrated on the target area to quickly remove stubborn residual powder. The second electric push rod 2072 can control the first toothed bar 2075 and the first gear 2053 to drive through the connecting frame 2074, thereby enabling the powder suction head 2054 to rotate and dynamically adjust its powder suction position to achieve uniform powder suction. The flexible switching and dynamic adjustment of the powder suction head 2054 significantly improves the powder cleaning efficiency and targeting.

[0023] Example 2: Refer to Figure 4 , Figure 7 and Figures 10-11 A powder-cleaning system for an adhesive spraying device includes a linear motion component 201. The linear motion component 201 includes two fixed plates 2011, which are fixedly connected to a housing 100. A motor 2012 is provided on one side of the fixed plate 2011. A screw 2013 is fixedly connected to the output shaft of the motor 2012. A threaded seat 2014 is threadedly connected to the screw 2013. Through the threaded transmission between the screw 2013 and the threaded seat 2014, the rotating air blowing component 206 can be displaced to perform powder blowing operations. The threaded seat 2014 is slidably connected to two guide rods 2015. The guide rods 2015 can guide the threaded seat 2014 to maintain stable movement. The two ends of the two guide rods 2015 are respectively fixedly connected to the two fixed plates 2011. The rotary air blowing assembly 206 includes an air blowing device 2061, which is mounted on a threaded seat 2014. The air outlet of the air blowing device 2061 is connected to a splitting head 2062. Airflow can be ejected through the air blowing device 2061 via the jet nozzle 2063, thereby enabling powder blowing. The splitting head 2062 can rotate via a bearing, allowing the jet nozzle 2063 to rotate smoothly for uniform powder blowing. The splitting head 2062 is rotatably mounted on the air outlet of the air blowing device 2061 via a bearing. Multiple inclined jet nozzles 2063 are arranged below the splitting head 2062.

[0024] In this embodiment: the screw 2013 is driven to rotate by the motor 2012, and the screw 2013 is threadedly driven by the threaded seat 2014, so that the threaded seat 2014 can rotate the air blowing assembly 206. The rotating air blowing assembly 206 can perform linear reciprocating motion by the forward and reverse rotation of the motor 2012, which increases the powder blowing area. The displacement of the rotating air blowing assembly 206 allows the second gear 2064 to drive the rack 202, so that the air jet head 2063 can rotate to blow away the accumulated powder evenly, avoiding cleaning dead corners caused by powder agglomeration.

[0025] Example 3: Reference Figure 1 , Figures 3-8 A powder cleaning system for an adhesive spraying device includes a powder cleaning mechanism 200. The powder cleaning mechanism 200 includes a linear motion component 201. A rotary air blowing component 206 is provided on the linear motion component 201. A second gear 2064 of the rotary air blowing component 206 meshes with a rack 202. The rack 202 is mounted on an air intake pipe 204. The air intake pipe 204 is mounted on two fixed plates 2011 of the linear motion component 201. A plurality of rotary air intake components 205 are provided below the air intake pipe 204. The linear motion assembly 201 has an intake rotation control assembly 207 and a valve single control assembly 208 on both sides of the threaded seat 2014. The first gear 2075 of the intake rotation control assembly 207 can mesh with the first gear 2053 of the rotating intake assembly 205 through displacement, so as to realize the rotation of the intake pipe. The valve single control assembly 208 can mesh with the toothed valve 2052 of the rotating intake assembly 205 downward, so as to open a single intake pipe. The toothed valves 2052 arranged in the same row can mesh with the toothed segment 2035 of the valve master control assembly 203, so as to synchronously control the opening and closing of multiple intake pipes.

[0026] In this embodiment: the linear motion component 201 drives the rotary air blowing component 206 to reciprocate, and during the motion, it cooperates with the rack 202 to perform a comprehensive powder blowing operation. When the powder is blown by displacement, the air intake rotation control component 207 drives the rotary air intake component 205 to rotate, so that the uniform powder blowing process is linked to achieve precise powder suction. When the powder is blown in a local area, the local air intake pipeline is opened by the valve single control component 208, so that the rotary air intake component 205 can still rotate to achieve precise powder suction. This achieves a combination of large-area uniform powder cleaning and local precise cleaning. The mechanical following method expands the dynamic powder suction range and can quickly complete synchronous suction. It can ensure the efficiency and uniformity of powder cleaning, and thoroughly remove residual powder, providing a strong guarantee for the accuracy of subsequent printing processes and the life of the equipment.

[0027] Working principle: During the powder cleaning operation, the screw 2013 is driven to rotate by the motor 2012. The screw 2013 drives the threaded seat 2014 to move the rotating air blowing assembly 206, which in turn drives the second gear 2064 to transmit power to the rack 202. The second gear 2064 drives the diverter head 2062 to rotate, which in turn drives the jet nozzle 2063 to rotate. At this time, the air blowing device 2061 can blow powder through the jet nozzle 2063. During the displacement process of the threaded seat 2014, the first toothed rod 2075 moves along with it and drives the first gear 2053. The first gear 2053 drives the connector 2051 and the dust suction head 2054 to rotate. At this time, the dust collection device 500 sucks up dust through multiple dust suction heads 2054 and evenly sucks up dust through the partially rotating dust suction head 2054. When localized powder blowing and cleaning are required, the movable bar 2033 is moved in advance by the first electric push rod 2031. The movable bar 2033 drives the toothed segment 2035 to drive the toothed valve 2052, closing all the toothed valves 2052. Then, the position of the valve single control component 208 is adjusted by the linear motion component 201, and the second toothed rod 2083 is driven downward by the second electric push rod 2072 to drive the toothed valve 2052, opening the connector 2051. The localized powder suction head 2054 is opened as needed, and then the air blowing component 206 is rotated to blow powder. At the same time, the second electric push rod 2072 is controlled to reciprocate, causing the connecting frame 2074 to drive the first toothed rod 2075 and the first gear 2053 to reciprocate, causing the powder suction head 2054 to rotate and suck up powder. The sucked powder enters the cyclone separator 400, which works with the industrial fan 300 to perform centrifugal separation. The separated powder enters the recovery bin 600 for recycling.

[0028] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
