Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cladding technology, specifically to a powder feeder for laser cladding equipment. Background Technology
[0002] Laser cladding, also known as laser bonding or laser coating, is a new surface modification technology. It involves adding cladding material to the surface of a substrate and using a high-energy-density laser beam to fuse it together with a thin layer on the substrate surface, thus forming a metallurgically bonded cladding layer on the substrate surface.
[0003] A powder feeder for laser cladding equipment, patent number CN202120326927.X, has the advantage of preventing solidification, solving the problem that existing laser cladding systems require metal powder for cladding, and the powder solidifies if stored in the container for too long, causing the laser cladding to malfunction and reducing efficiency. However, it still has some drawbacks in practical use: First, while it prevents solidification through internal stirring, the lack of heating and drying measures during stirring makes it possible for the powder to solidify again after stirring; second, it is difficult to control the powder flow rate during powder feeding, easily leading to overfeeding. Utility Model Content
[0004] The purpose of this utility model is to provide a powder feeder for laser cladding equipment, so as to solve the problem mentioned in the background art. This technical solution can provide heating and drying measures, and at the same time, it can control the flow rate of powder.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder feeder for laser cladding equipment, comprising a temporary storage box, two feed ports on the top of the temporary storage box, a motor fixedly connected to the top, a rotating rod fixedly connected to the bottom of the motor, the bottom end of the rotating rod penetrating through the top of the temporary storage box and movably connected to the top of the temporary storage box, and several stirring blades fixedly connected to the outside of the rotating rod, each of the stirring blades having a heating element fixedly installed on its outside, a guide tube inserted and fixedly installed at the bottom of the temporary storage box, an adjusting component provided in the inner cavity of the guide tube, a pump body inserted and installed at the bottom of the guide tube, and a powder feeding pipe inserted and installed at the bottom of the pump body.
[0006] Preferably, the adjustment component includes a soft plug located inside the catheter lumen, and round shafts are fixedly connected to both sides of the soft plug. The end of the round shaft away from the soft plug passes through the outer wall of the catheter and is movably connected to the outer wall of the catheter. A gear is fixedly connected to one end of the round shaft, and racks mesh with the outer sides of the two gears. An electric push rod is fixedly installed at the bottom of the two racks.
[0007] Preferably, the bottom of the electric push rod is fixedly connected to a fixing seat, and the fixing seat is fixedly connected to the outer wall of the conduit.
[0008] Preferably, a plurality of connecting frames are fixedly connected to the outer wall of the pump body, and the tops of the plurality of connecting frames are fixedly connected to the outer wall of the temporary storage box.
[0009] Preferably, the top of the temporary storage box is provided with two pistons, and the bottoms of the two pistons are respectively inserted into the inner cavity of the corresponding feed inlet.
[0010] Preferably, a connecting strip is fixedly connected to the top of each of the two pistons, and the end of the connecting strip away from the piston is fixedly connected to the top of the temporary storage box.
[0011] Preferably, two fixing rings are fixedly installed on the outer side of the temporary storage box. The two fixing rings are arranged vertically, and a mounting plate is fixedly connected to the rear side of each of the two fixing rings. The mounting plate has two mounting holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. Equipped with a motor, stirring blades, and heating elements, the heating elements and motor are driven after all the powder enters the temporary storage box. The heating elements heat the inside of the temporary storage box while simultaneously heating multiple stirring blades. At the same time, the motor drives multiple stirring blades on the rotating rod to stir the powder inside the temporary storage box. The stirring, combined with the drying effect produced by heating, can achieve the effect of preventing the powder from curing and ensure that secondary curing will not occur later.
[0014] 2. By incorporating a soft plug, gears, and racks, when it is necessary to control the flow rate of powder inside the conduit, two electric push rods can be driven simultaneously. Each push rod moves its corresponding rack, which in turn drives its corresponding gear to rotate. The gears then rotate their corresponding shafts, which together cause the soft plug to deflect inside the conduit. When the soft plug deflects to a horizontal position, the conduit is closed. When it deflects to a vertical position, the flow inside the conduit is smoothest. After the soft plug has moved to the appropriate angle, the two electric push rods are closed. To readjust the flow rate later, simply repeat the above steps. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a powder feeder for laser cladding equipment, including a temporary storage box 1. The top of the temporary storage box 1 has two feed ports 5, and a motor 8 is fixedly connected to the top. A rotating rod 9 is fixedly connected to the bottom of the motor 8. The bottom end of the rotating rod 9 passes through the top of the temporary storage box 1 and is movably connected to the top of the temporary storage box 1. Several stirring blades 10 are fixedly connected to the outside of the rotating rod 9. Heating plates 11 are fixedly installed on the outside of each of the stirring blades 10. A conduit 12 is inserted and fixedly installed at the bottom of the temporary storage box 1. An adjustment component is provided in the inner cavity of the conduit 12. A pump body 13 is inserted and installed at the bottom of the conduit 12. A powder feeding pipe 15 is inserted and installed at the bottom of the pump body 13.
[0023] The motor 8 drives multiple stirring blades 10 on the rotating rod 9 to stir and disperse the powder. At the same time, it works with multiple heating elements 11 to achieve a certain heating and drying effect, avoiding the problem of powder solidification. The powder is then pumped out by the pump body 13 and sent to the appropriate position through the powder delivery pipe 15 for subsequent work.
[0024] Please see Figure 4 and Figure 5The adjustment assembly includes a soft plug 16, which is located inside the conduit 12. Both sides of the soft plug 16 are fixedly connected to a round shaft 17. The end of the round shaft 17 away from the soft plug 16 passes through the outer wall of the conduit 12 and is movably connected to the outer wall of the conduit 12. A gear 18 is fixedly connected to one end of the round shaft 17. Both gears 18 have racks 19 meshing on their outer sides. Both racks 19 have electric push rods 20 fixedly installed at their bottoms.
[0025] In this process, the electric push rod 20 is used to push the rack 19 to move, the rack 19 drives the round shaft 17 on the gear 18 to rotate, and the two round shafts 17 together drive the soft plug 16 to deflect inside the guide tube 12. The above is the process of adjusting the powder flow rate inside the guide tube 12, which is easy to operate.
[0026] Please see Figure 4 and Figure 5 The bottom of the electric push rod 20 is fixedly connected to a fixed seat 21, and the fixed seat 21 is fixedly connected to the outer wall of the conduit 12.
[0027] The fixing seat 21 is used to fix the electric push rod 20 to the outer wall of the conduit 12, so as to ensure the stability of the electric push rod 20 during subsequent operation.
[0028] Please see Figure 1 and Figure 2 Several connecting brackets 14 are fixedly connected to the outer wall of the pump body 13, and the top of each connecting bracket 14 is fixedly connected to the outer wall of the temporary storage box 1.
[0029] Multiple connecting brackets 14 are used to fix the pump body 13 to the outer wall of the temporary storage box 1, ensuring the stable performance of the pump body 13 during subsequent operation.
[0030] Please see Figure 1 and Figure 2 The top of the temporary storage box 1 is equipped with two pistons 6, and the bottom of the two pistons 6 are respectively inserted into the inner cavity of the corresponding feed inlet 5.
[0031] Two pistons 6 are used to block the two feed inlets 5 to prevent external debris from entering the temporary storage box 1.
[0032] Please see Figure 1 and Figure 2 Both pistons 6 are fixedly connected to the top of a connecting strip 7, and the end of the connecting strip 7 away from the piston 6 is fixedly connected to the top of the temporary storage box 1.
[0033] The piston 6 is connected to the top of the temporary storage box 1 by the connecting strip 7, which prevents the piston 6 from falling after it is removed.
[0034] Please see Figure 1 and Figure 2Two fixing rings 2 are fixedly installed on the outer side of the temporary storage box 1. The two fixing rings 2 are arranged vertically, and the rear side of each fixing ring 2 is fixedly connected to a mounting plate 3. The mounting plate 3 has two mounting holes 4.
[0035] The installation of the entire device can be easily achieved by cooperating with the mounting plate 3 and the fixing ring 2. That is, the fastening bolt is passed through the mounting hole 4 and the mounting plate 3 is fixed to the wall or other positions to achieve the fixed installation of the device.
[0036] Working principle: When using this application, firstly, the two pistons 6 are removed from the inside of the feed port 5, and then all the powder is fed into the temporary storage box 1 through the two feed ports 5. Then, the pistons 6 are reinserted into the feed port 5 to prevent external debris from entering the temporary storage box 1 through the open feed port 5. Next, the heating plate 11 and the motor 8 are driven. While the heating plate 11 heats the inside of the temporary storage box 1, it can also heat the multiple stirring blades 10. At the same time, the motor 8 drives the multiple stirring blades 10 on the rotating rod 9 to stir the powder inside the temporary storage box 1. The stirring is accompanied by the drying effect produced by heating, which can achieve the effect of preventing the powder from curing and ensure that secondary curing will not occur later.
[0037] When feeding is required, the two electric push rods 20 are driven synchronously, causing the two electric push rods 20 to drive the corresponding racks 19 to move. The two racks 19 drive the corresponding gears 18 to rotate, and the two gears 18 drive the corresponding round shafts 17 to rotate. The two round shafts 17 together drive the soft plug 16 to deflect inside the guide tube 12. When the soft plug 16 deflects to a horizontal state, the inside of the guide tube 12 is closed. When the soft plug 16 deflects to a vertical state, the flow inside the guide tube 12 is the smoothest. During the movement of the soft plug 16, the flow rate of powder inside the guide tube 12 is adjusted. After adjusting to a suitable angle, the two electric push rods 20 are turned off, and the pump body 13 is driven to draw powder and then send the powder to a suitable position through the powder feeding pipe 15 for subsequent work.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
