Description

Technical Field

[0001] The invention relates to the technical field of laser cladding, and in particular to a laser cladding powder conveying and anti-blocking device. Background Art

[0002] Laser cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding material to the surface of the substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate.

[0003] At present, when the laser cladding powder feeding device is in use, powder is mainly transported through a feeding pipe. However, the powder in the feeding pipe is prone to agglomerated powder during the transportation process, which causes the feeding pipe to be blocked and unable to continuously feed, thus affecting the laser cladding. At the same time, after being blocked, it is necessary to stop working and clear the feeding pipe, which causes inconvenience in operation and affects efficiency. As a result, the laser cladding powder feeding device is prone to blockage in the pipeline when feeding powder, affecting the transportation. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 14 As shown, a laser cladding powder conveying and anti-blocking device comprises a drying mechanism 10, a crushing mechanism 20 and an anti-blocking mechanism 30, wherein: The drying mechanism 10 comprises a drying tank 101, wherein a plurality of collecting hoppers 112 are rotatably connected inside the drying tank 101, a heating disk 111 is coaxially distributed inside the collecting hopper 109, and a plurality of heating rods 115 are evenly embedded in the heating disk 111. When the wet and agglomerated powder passes through the gap between the heating disk 111 and the collecting hopper 112, the powder is dried by the heated heating disk 111. The pulverizing mechanism 20 is disposed above the drying tank 101 and includes a pulverizing cylinder 201, wherein a pulverizing shaft 202 is rotatably connected to the inside of the pulverizing cylinder 201, and a plurality of pulverizing rods 203 are spaced apart on the pulverizing shaft 202. When the wet agglomerated powder passes through the inside of the pulverizing cylinder 201, the pulverizing rods 203 on the pulverizing shaft 202 are used to pulverize the agglomerates in the wet powder. The anti-blocking mechanism 20 is arranged beside the grinding cylinder 201 and includes a knocking block 305 . The knocking block 305 regularly knocks the outer wall of the grinding cylinder 201 , and the vibration generated is used to clear the powder in the grinding cylinder 201 .

[0034] In this embodiment, a number of feed ports 101a are evenly distributed on the top surface of the drying tank 101, a discharge port 101b is centrally provided at the bottom of the drying tank 101, and a number of moisture discharge ports 101c are also evenly distributed on the top of the drying tank 101. Above the drying tank 101, there is a double-headed motor 105, and the double-headed motor 105 is centrally installed on the upper side of the drying tank 101 through a "day"-shaped fixing frame 106. A pulley one 107 is key-connected to the lower output shaft of the double-headed motor 105. At the rear of the top of the drying tank 101, there is a crankshaft 108 rotatably connected, and a pulley two 109 is key-connected to the upper end of the crankshaft 108, and a belt one 110 is connected between the pulley two 109 and the pulley one 107. Inside the drying tank 101, a connecting shaft 111 is rotatably connected coaxially. A number of collecting hoppers 112 are coaxially sleeved on the connecting shaft 111. A conical dispersion cover 113 is integrally connected to the center of each collecting hopper 112, and dispersion holes 112a are evenly distributed at the connection between the two. The dispersion cover 113 is coaxially fixed to the connecting shaft 111. The heating plate 114 is installed inside the drying cylinder 101 through a number of fixing strips 116. The upper part of the connecting shaft 111 is telescopically connected with a connecting strip 117, and a connecting groove 117a is provided at the telescopic end of the connecting strip 117. The lower end of the crankshaft 108 is slidably connected inside the connecting groove 117a. When the damp and agglomerated powder falls onto the surface of the uppermost heating plate 114 through the feed port 101a, after the double-headed motor 105 is transmitted through the belt drive system and the crank rocker mechanism composed of the crankshaft 108 and the connecting strip 117, it drives the collecting hoppers 112 and the dispersion cover 113 on the connecting shaft 111 to rotate reciprocally, and then gradually transfers the damp and agglomerated powder from the uppermost collecting hopper 112 to the lowermost collecting hopper 112. When passing through the gap formed by the collecting hopper 112 and the heating plate 114, the heated heating plate 111 is used to dry these powders. The moisture during drying is discharged from the drying tank 101 through the moisture discharge port 101c, and the dried powder then falls to the discharge port 101b of the drying tank 101.

[0035] In this embodiment, the crushing cylinder 201 is provided with a plurality of them and vertically installed above each feed port 101a, and a feed port 201a is obliquely provided at the upper end of the crushing cylinder 201, the upper end of the crushing shaft 202 is keyed to a pulley 3 205, and a belt 206 is connected between all the pulleys 3 205, and a pulley 4 207 is keyed to the upper output shaft of the double-headed motor 105, and a belt 3 208 is connected between the pulley 4 207 and one of the pulleys 3 205. When the wet agglomerated powder enters the upper layer of the crushing cylinder 201 through the feed port 201a, the double-headed motor 105 drives the crushing rod 203 on the crushing shaft 202 to rotate after being driven by the belt transmission system, and the crushing rod 203 on the crushing shaft 202 is used to crush the agglomerates in the wet powder, and the crushed powder enters the drying tank 101 through the feed port 101a.

[0036] In this embodiment, the drying tank 101 is vertically connected to a mounting shell 301 beside the crushing cylinder 201. A plurality of mounting grooves 301a are evenly distributed in the middle of the mounting shell 301. A pair of mounting plates 302 are symmetrically welded on the upper and lower sides of each mounting groove 301a. Two V-shaped connecting arms 303 are hinged between the mounting plates 302. A gear 304 is connected to the hinge of the connecting arm 303, and two adjacent gears 304 are meshed with each other. The striking block 305 is welded to the outer end of the connecting arm 303, and a compression spring 306 is connected between the connecting arm 303 and the mounting shell 301. The upper output shaft of the double-headed motor 105 is also keyed to a "human" shaped rotating frame 307, and a spiral toggle bar 308 is fixed to each end of the rotating frame 307. When the toggle bar 308 passes by the side of the mounting shell 301, the toggle bar 308 contacts the inner end of each row of connecting arms 303 in an orderly manner from bottom to top. The double-headed motor 105 drives the toggle bar 308 on the rotating frame 307 to rotate. When the toggle bar 308 passes by the side of the mounting shell 301, the toggle bar 308 contacts the inner ends of each row of connecting arms 303 in an orderly manner from bottom to top, thereby toggling each pair of connecting arms 303 to expand outward, and separating the knocking blocks 305 at the outer ends of the connecting arms 303 from the outer wall of the crushing barrel 201. When the toggle bar 308 loses contact with the inner ends of the connecting arms 303, the knocking blocks 305 at the outer ends of the connecting arms 303 will quickly knock on the outer wall of the crushing barrel 201 under the action of the compression spring 306, and the vibration generated will clear the powder in the crushing barrel 201 to avoid blockage.

[0037] In this embodiment, an inspection port 101d is provided on the side of the drying tank 101, and a sealing cover 102 is hingedly connected to the inspection port 101d. The inspection port 101d facilitates inspection and maintenance of the interior of the drying tank 101.

[0038] In this embodiment, a butterfly valve 104 is connected below the discharge port 101b via a clamp 103. The butterfly valve 104 can adjust the opening of the discharge port 101b, thereby adjusting the flow of the dried powder.

[0039] In this embodiment, arc-shaped dispersion strips 1121 are staggeredly distributed on the inner wall surface of the collecting hopper 112. These dispersion strips 1121 can not only increase the time for the powder to pass through the gap between the collecting hopper 112 and the heating plate 114, but also further break up the wet and agglomerated powder, thereby improving the drying effect of the powder.

[0040] In this embodiment, the upper edge of the heating disk 114 is chamfered, and a plurality of scraper plates 1122 are evenly distributed on the upper edge of the collecting hopper 112, and the inner edge of the scraper plates 1122 is in contact with the chamfered surface of the heating disk 114. When powder falls onto the chamfered surface of the heating disk 114, the powder can be scraped into the collecting hopper 112 by the scraper plates 1122 around it.

[0041] In this embodiment, a spiral conveying plate 204 is welded to the outer side of the pulverizing shaft 202, and the pitch of the conveying plate 204 gradually decreases from top to bottom. The conveying plate 204 can not only convey the powder downward, but also squeeze and crush the agglomerates in the powder.

[0042] The working principle of this laser cladding powder conveying anti-blocking equipment: The wet agglomerated powder enters the upper layer of the pulverizing cylinder 201 through the feeding port 201a, and the double-headed motor 105 drives the pulverizing rod 203 on the pulverizing shaft 202 to rotate after being driven by the belt transmission system, and the pulverizing rod 203 on the pulverizing shaft 202 is used to pulverize the agglomerates in the wet powder. The crushed powder falls onto the surface of the uppermost heating plate 114 through the feed port 101a, and the double-headed motor 105 drives the collecting bucket 112 and the dispersion cover 113 on the connecting shaft 111 to reciprocate after being driven by the belt transmission system and the crank rocker mechanism composed of the crankshaft 108 and the connecting bar 117, thereby gradually transferring the wet and agglomerated powder from the uppermost collecting bucket 112 to the lowermost collecting bucket 112, and when passing through the gap formed by the collecting bucket 112 and the heating plate 114, the powder is dried by the heated heating plate 111, and the moisture during drying is discharged from the drying tank 101 through the dehumidification port 101c, and the dried powder falls to the discharge port 101b of the drying tank 101.

[0043] When crushing wet and agglomerated powder, the double-headed motor 105 drives the toggle bar 308 on the rotating frame 307 to rotate. When the toggle bar 308 passes by the side of the mounting shell 301, the toggle bar 308 contacts the inner ends of each row of connecting arms 303 in an orderly manner from bottom to top, thereby toggling each pair of connecting arms 303 to expand outward, and separating the knocking blocks 305 at the outer ends of the connecting arms 303 from the outer wall of the crushing barrel 201. When the toggle bar 308 loses contact with the inner ends of the connecting arms 303, the knocking blocks 305 at the outer ends of the connecting arms 303 will quickly knock on the outer wall of the crushing barrel 201 under the action of the compression spring 306, and the vibration generated will clear the powder in the crushing barrel 201 to avoid blockage.

[0044] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
