[0036] Embodiment 1:

[0037] See also Figure 1 - Fig. 9 As shown, a low melting point metal powder hot melt forming equipment for metallurgy, comprising:

[0040] The hot melt assembly 3 includes a U-shaped frame 31, a cover plate 33 is movably mounted inside the U-shaped frame 31, the cover plate 33 is attached to the outer wall of the placement frame 26, a heating plate 34 is fixedly mounted on the bottom of the placement frame 26, a first proximity sensor 36 is fixedly mounted on one side of the mounting plate 24, and a second proximity sensor 37 is fixedly mounted inside the U-shaped frame 31;

[0041] The feeding assembly 4 includes a support frame 41, a feeding bucket 42 is fixedly installed at one end of the support frame 41, a feeding pipe 43 is fixedly installed at the bottom of the feeding bucket 42, a solenoid valve 44 is arranged on one side of the feeding pipe 43, a barrel cover 45 is movably installed on the top of the feeding bucket 42, a dust sensor 46 is arranged on one side of the barrel cover 45, and a powder loosening shaft 49 is movably installed inside the feeding bucket 42;

[0042] The cooling and collecting component 5 comprises a water tank 51 , a water pump 52 is fixedly mounted on one side of the water tank 51 , and a delivery pipe 53 is connected to one side of the water pump 52 .

[0043] See also Figure 3 - Figure 5As shown, specifically, a plurality of support bars 21 are fixedly installed on the top of the belt 14, support plates 22 are fixedly connected between the support bars 21, two support columns 23 are symmetrically installed on the top of the support plate 22, mounting plates 24 are fixedly installed on the two support columns 23 on the side away from the support plate 22, limiting rods 25 are fixedly installed on the top of the mounting plates 24, a placement frame 26 is movably installed on the side of the mounting plate 24 away from the support plate 22, a reset plate 27 is movably sleeved on the outer side of the limiting rod 25, the reset plate 27 is fixedly connected to the placement frame 26 on the side close to the placement frame 26, a damping spring 28 is connected between the reset plate 27 and the mounting plate 24, and an infrared ranging sensor 29 is fixedly installed on the side of the mounting plate 24 close to the reset plate 27.

[0044] As can be seen from the above, the No. 1 driving motor 15 drives the belt 14 to transport by driving the belt roller 13 to rotate. The support bar 21 is fixedly connected to the support plate 22, so that the support plate 22 can move synchronously with the belt 14, thereby realizing the transportation of the placement frame 26. The damping spring 28 can drive the placement frame 26 to complete the reset, and the infrared ranging sensor 29 can monitor the position of the placement frame 26 in real time.

[0045] When in use, metal powder is put into the placement frame 26. At this time, the weight of the placement frame 26 increases, and the damping spring 28 is compressed. At this time, the reset plate 27 will be closer to the mounting plate 24. The infrared ranging sensor 29 will detect the downward movement of the reset plate 27, which means that enough metal powder has been placed in the placement frame 26. It will send an electrical signal to the No. 1 drive motor 15, and the No. 1 drive motor 15 will drive the belt 14 to transport the placement frame 26 and transport the placement frame 26 to the direction of the U-shaped frame 31.

[0046] Embodiment 2:

[0047] See also Figure 1 - Figure 5 As shown, a U-shaped frame 31 is connected between the two side panels 12, an electric push rod 32 is fixedly installed on the top of the U-shaped frame 31, a cover plate 33 is movably installed on the side of the U-shaped frame 31 close to the placement frame 26, and the output end of the electric push rod 32 passes through the U-shaped frame 31 and is fixedly connected to one side of the cover plate 33.

[0048] See also Figure 4 - Figure 5 As shown, specifically, a heating plate 34 is fixedly installed on the bottom of the placement frame 26, a heater 35 is fixedly installed on the side of the support plate 22 close to the heating plate 34, the heater 35 is electrically connected to the heating plate 34, a first proximity sensor 36 is fixedly installed on one side of the mounting plate 24, and a second proximity sensor 37 is fixedly installed on the side of the U-shaped frame 31 close to the placement frame 26.

[0049] As can be seen from the above, the electric push rod 32 can push the cover 33 to cover the top of the placement frame 26, so that the metal powder will not splash during the heating and melting process. The heater 35 controls the heating plate 34 to heat up and melt the metal powder inside the placement frame 26. When the position of the No. 1 proximity sensor 36 corresponds to the position of the No. 2 proximity sensor 37, it indicates that the cover 33 is directly above the placement frame 26, and the belt 14 stops transporting.

[0050] During use, when the placement frame 26 reaches the inner side of the U-shaped frame 31 under the transportation of the belt 14, the positions of the No. 1 proximity sensor 36 and the No. 2 proximity sensor 37 correspond, and an electrical signal will be sent to the No. 1 drive motor 15. The No. 1 drive motor 15 stops outputting for five seconds. At the same time, the heating plate 34 heats up, and the metal powder inside the placement frame 26 begins to melt. The electric push rod 32 pushes the cover plate 33 to cover the top of the placement frame 26. After five seconds, the No. 1 drive motor 15 starts again, driving the placement frame 26 to move toward the water tank 51.

[0051] Embodiment three:

[0052] See also Figure 1 - Figure 2 and Figure 6 - Figure 7 As shown, a support frame 41 is fixedly installed on the top of the base plate 1 near the conveying bracket 11, a feeding bucket 42 is fixedly installed on the top of the support frame 41, a feeding pipe 43 is fixedly installed on the side of the feeding bucket 42 near the placement frame 26, a solenoid valve 44 is provided on one side of the feeding pipe 43, a barrel cover 45 is movably installed on the top of the feeding barrel 42, a dust sensor 46 is fixedly installed on the top of the barrel cover 45, and an LED indicator light 47 is fixedly installed on one side of the feeding barrel 42.

[0053] See also Figure 7 As shown, specifically, a transverse plate 48 is fixedly installed on one side of the feeding barrel 42, a powder loosening shaft 49 is movably installed on one side of the transverse plate 48 through a bearing, a driven bevel gear 410 is movably installed on the side of the transverse plate 48 away from the powder loosening shaft 49, a rotating shaft 411 is movably installed on the side of the feeding barrel 42 close to the transverse plate 48 through a bearing, an end of the rotating shaft 411 close to the driven bevel gear 410 is connected to a driving bevel gear 412, and the driving bevel gear 412 is meshed with the driven bevel gear 410, and a No. 2 driving motor 413 is installed on the outside of the feeding barrel 42 close to the rotating shaft 411 through a fixed seat, and the output end of the No. 2 driving motor 413 is connected to the shaft transmission of the rotating shaft 411 through a coupling.

[0054] As can be seen from the above, the inside of the feeding barrel 42 is used to store metal powder, the solenoid valve 44 can control the metal powder to be thrown into the placement frame 26 through the feeding pipe 43, so as to achieve the purpose of automatic unloading, and the dust sensor 46 can monitor the remaining metal powder in the feeding barrel 42 in real time. When it detects that the remaining metal powder is small, it will send an electrical signal to the LED indicator 47, and the LED indicator 47 will emit red light, otherwise it will emit green light. The powder loosening shaft 49 can rotate slowly inside the feeding barrel 42 to prevent powder accumulation and difficulty in leaving the feeding barrel 42 from the feeding pipe 43. Through the cooperation of the active bevel gear 412 and the driven bevel gear 410, the powder loosening shaft 49 is driven by the No. 2 drive motor 413 to rotate.

[0055] When in use, first start the second drive motor 413 to drive the powder loosening shaft 49 to rotate slowly, and then open the electromagnetic valve 44, so that the metal powder can be thrown into the placement frame 26 more smoothly from the feeding pipe 43.

[0056] Embodiment 4:

[0057] See also Figure 1 - Figure 2 As shown, the water tank 51 is fixedly installed on the side of the bottom plate 1 away from the support frame 41 , and the output end of the delivery pipe 53 faces the placement frame 26 .

[0058] See also Figure 1 - Fig. 9 As shown, it also includes a switching power supply, a control module and a power module. The switching power supply supplies power to the entire device. The output end of the switching power supply is electrically connected to the power module. The power module is connected to a main power switch through a line. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The infrared ranging sensor 29 and the No. 1 proximity sensor 36, the No. 2 proximity sensor 37 and the dust sensor 46 are all electrically connected to the control module. The No. 1 drive motor 15, the No. 2 drive motor 413, the LED indicator light 47, the water pump 52, the solenoid valve 44, the electric push rod 32, and the heating plate 34 are all connected to the control module through a relay control module.

[0059] As can be seen from the above, a sufficient amount of water needs to be stored in the water tank 51 in advance, and the water pump 52 transports the water in the water tank 51 to the inside of the placement frame 26 through the transport pipe 53 .

[0060] During use, when the heated placement frame 26 is close to the water tank 51, the control module controls the water pump 52 to run for two seconds, and the water flows to the inside of the placement frame 26 through the delivery pipe 53. Then the belt 14 continues to drive the placement frame 26 to move. When it moves to the edge of the belt 14, the placement frame 26 will flip to one side of the water tank 51, and the metal block formed inside it will fall into the water tank 51. At this time, the formed metal block can be taken away.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
