Description

Technical Field

[0001] This utility model relates to the field of laser cladding machine technology, and more specifically, to a laser cladding machine equipped with an adaptive powder conveying mechanism. Background Technology

[0002] Laser cladding machines are devices that use high-energy laser beams to melt metallic or non-metallic materials and deposit them on the surface of a substrate to form a metallurgically bonded coating or repair layer. They are widely used in industrial repair, surface strengthening, additive manufacturing and other fields.

[0003] A search revealed CN221166752U, which discloses an anti-clogging powder feeder for a laser cladding machine. The feeder includes a powder feeding box with a powder outlet on its bottom surface. One end of a powder conveying pipe is fixedly connected to the bottom of the powder outlet. A first sealing ring is fixedly connected to the top of the outer wall of the powder feeding box. The top of the powder feeding box is snapped into a sealing cover, the bottom surface of which contacts the top surface of the first sealing ring. The inner wall of the sealing cover and the top of the outer wall of the powder feeding box are respectively threaded and interlocked. A sealing groove is provided on the top surface of the powder feeding box. A second sealing ring is fixedly connected to the bottom surface of the sealing cover and snapped into the sealing groove. A fixed handle is fixedly connected to the top surface of the sealing cover. The outer side of a heating plate is fixedly connected around the inner wall of the powder feeding box.

[0004] However, this anti-clogging powder feeder for laser cladding machines still has some drawbacks. For example, although the above-mentioned technical solution can effectively reduce the risk of clogging during the feeding process of the cladding material through measures such as filtration and heating, in actual operation, when workers unpack the material and pour the cladding material into the powder feeder, there is still a problem of powder scattering. This scattering phenomenon may cause dust to be inhaled by operators, thus posing a potential threat to health and safety. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a laser cladding machine equipped with an adaptive powder conveying mechanism, so as to solve the problem that although some solutions in the prior art can reduce the blockage of cladding materials, they are prone to powder scattering during unpacking and dumping, which poses a safety hazard of workers inhaling dust.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a laser cladding machine equipped with an adaptive powder conveying mechanism, comprising...

[0007] The powder feeder body has a connecting pipe threaded to its top, a feeding box fixedly installed on the top of the connecting pipe, and a motor fixedly installed in the middle of the side of the feeding box.

[0008] The tipping bucket is rotatably installed in the middle of the feeding box. Two electric telescopic rods are fixed on the inner wall of the top of the tipping bucket on the side away from the motor. A connecting rod is fixedly installed at the end of the two electric telescopic rods. A movable block is slidably installed on the outer surface of the connecting rod. An electric telescopic rod is fixedly installed on the inner surface of the end of the movable block away from the connecting rod. A cutter is fixedly installed at the bottom end of the electric telescopic rod.

[0009] Two protruding pillars are fixedly installed in the middle of both sides of the tipping bucket, and the two protruding pillars are symmetrically arranged.

[0010] The gears are provided in two parts, which mesh with each other, and the inner surface of the middle part is fixedly sleeved with the outer surface of the end of the convex column and the outer surface of the output end of the motor, respectively.

[0011] The bottom of the tipping bucket is movably mounted with a movable plate, and a second motor is fixedly mounted on the side of the end of the connecting rod. A lead screw is fixedly sleeved on the output end of the second motor. The outer surface of the end of the lead screw away from the second motor is rotatably mounted with the inner surface of the side wall of the tipping bucket, and the outer surface of the lead screw is threadedly connected to the inner surface of the middle part of the movable block.

[0012] The upper surfaces of both sides of the movable plate in the width direction are provided with pressing mechanisms. Multiple movable rods are fixedly installed on the lower surface of the movable plate. A sleeve is slidably sleeved on the outer surface of the bottom end of each of the multiple movable rods. A spring is provided in the inner cavity of the bottom end of the sleeve, and the outer surface of the sleeve is fixedly installed with the inner surface of the bottom of the tilting bucket. One end of the spring is fixedly connected to the inner surface of the bottom of the sleeve, and the other end is fixedly connected to the lower surface of the movable rod.

[0013] Among them, a motor three is fixedly installed on the lower surface of the middle part of the movable plate, and an elliptical plate is fixedly sleeved on the output end of the motor three. The outer edge of the elliptical plate is in contact with the lower surface of the movable plate.

[0014] The clamping mechanism includes threaded rods and a rotating wheel. Two threaded rods are arranged parallel to each other on one side of the movable plate, and the outer surfaces of the bottom ends of the two threaded rods are rotatably mounted to the inner surface of the movable plate. A transmission mechanism is provided on the outer surface of the top end of the two threaded rods. A pressing plate is threadedly connected to the outer surfaces of the two threaded rods. The bottom end of the rotating wheel is fixedly mounted to the top end of the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the above scheme, by setting up structures such as a tilting bucket and a cutter, when replenishing the cladding material inside the powder feeder body, after screwing the connecting pipe to the outside of the top feed pipe of the powder feeder body, the bagged cladding material can be arranged and placed flat on the top of the movable plate. The pressing mechanism is then adjusted to press the edge of the cladding material packaging bag tightly against the surface of the movable plate. Then, the motor drives the gear to rotate, causing the gear installed at the end of the protruding column to rotate as well, tilting the tilting bucket, the movable plate inside, the packaging bag, etc., inside the feeding box. Next, by controlling and adjusting the electric telescopic rod one, motor two, etc., the cutter is pulled to cut open the packaging bag. At this time, the cladding material inside the packaging bag will flow into the inside of the powder feeder body along the inner wall of the feeding box and the connecting pipe, thereby reducing the powder drift during the replenishment of cladding material inside the powder feeder body and improving the safety of the device.

[0017] In the above scheme, by setting up structures such as motor three and elliptical plates, during the pouring of the cladding material, the staff can also control the elliptical plate connected to the output end of motor three to rotate. During the rotation of the elliptical plate, the diameter changes continuously, pushing the adjacent movable plate to move to a certain extent. During this movement, the movable rod connected to the movable plate will move on the inner surface of the sleeve, pulling the connected spring to stretch and retract, causing the movable plate and the packaging bag pressed on the surface to rise and fall and vibrate, thereby facilitating the shaking off of the residual cladding material inside the packaging bag.

[0028] Two protruding pillars 5 are fixedly installed in the middle of both sides of the tipping bucket 4, and the two protruding pillars 5 are symmetrically arranged.

[0029] There are two gears 6, which mesh with each other, and the inner surface of the middle part is fixedly sleeved with the outer surface of the end of the protrusion 5 and the outer surface of the output end of the motor 7, respectively.

[0030] Among them, a movable plate 8 is movably installed at the bottom of the tilting bucket 4, a motor 11 is fixedly installed on the side of the end of the connecting rod 10, a lead screw 12 is fixedly sleeved at the output end of the motor 11, the outer surface of the end of the lead screw 12 away from the motor 11 is rotatably installed with the inner surface of the side wall of the tilting bucket 4, and the outer surface of the lead screw 12 is threadedly connected to the inner surface of the middle part of the movable block 13.

[0031] By setting up an electric telescopic rod 14 and a motor 11, when cutting the bag, first control the electric telescopic rod 14 to descend so that the cutter 15 can be inserted into the inside of the cladding material packaging bag. Then control the motor 11 to drive the lead screw 12 to rotate. The movable block 13, which is threaded to the outer surface of the lead screw 12, moves laterally along the outer surface of the connecting rod 10, driving the cutter 15 to cut the packaging bag laterally. The electric telescopic rod 14 can also be controlled to extend so that the cutter 15 can cut a "U"-shaped opening on the surface of the cladding material packaging bag, so as to fully release the cladding material inside the packaging bag.

[0032] The upper surfaces of both sides of the movable plate 8 in the width direction are provided with pressing mechanisms 16. Multiple movable rods 19 are fixedly installed on the lower surface of the movable plate 8. The outer surfaces of the bottom ends of the multiple movable rods 19 are slidably sleeved with sleeves 17.

At this time, the cladding material inside the packaging bag will flow into the inside of the powder feeder body 1 along the inner wall of the feeding box 2 and the connecting pipe 3.

[0038] In addition, during the pouring of the cladding material, the staff can also control the elliptical plate 21 connected to the output end of the motor 320 to rotate. During the rotation of the elliptical plate 21, the diameter changes continuously, which pushes the adjacent movable plate 8 to move to a certain extent. During this movement, the movable rod 19 connected to the movable plate 8 will move on the inner surface of the sleeve 17, pulling the connected spring 18 to stretch and retract, so that the movable plate 8 and the packaging bag pressed on the surface will vibrate up and down.
