Description

Technical Field

[0001] This utility model relates to the field of industrial production, and in particular to a feeding device for a gold melting machine. Background Technology

[0002] Gold melting machines, operating on the principle of variable frequency electromagnetic induction heating, possess significant advantages such as high-efficiency heating, low energy consumption, and high thermal efficiency, and are widely used in gold and silver processing, casting, and other fields. However, in current small and medium-sized gold melting machines, the feeding process often relies on manual operation. Especially when processing sheet-like, loose metal sheets, multiple feeding operations are necessary because the entire process cannot be completed in one go. Given the high temperature of the furnace during operation, operators are highly susceptible to burns during feeding, posing a significant safety risk, and even slight carelessness could lead to accidents. Therefore, developing a feeding device for gold melting machines that effectively improves safety performance has become an urgent priority, and the aforementioned problems must be addressed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology in the feeding process, the technical problem of this utility model is to provide a feeding device for a gold melting machine with high safety performance.

[0004] A feeding device for a gold melting machine includes a controller, a furnace for gold melting fixedly connected to the controller, a mounting base fixedly connected to the controller, a sliding groove on the mounting base, a slider slidably connected within the sliding groove, a connecting plate fixedly connected to the slider, a feeding hopper fixedly connected to the connecting plate, the feeding hopper being wedge-shaped with the left side higher than the right, the right outlet of the feeding hopper being located at the top of the furnace, a conveying pipe fixedly connected to the connecting plate, a first motor fixedly connected to the left side of the conveying pipe, a feeding inlet fixedly connected to the top of the conveying pipe, a spiral tube for feeding rotatably connected inside the conveying pipe, and the output shaft of the first motor fixedly connected to the spiral tube via a coupling, an operating switch fixedly connected to the front of the conveying pipe, the operating switch being electrically connected to the first motor.

[0005] Optionally, it also includes a fixing plate, which is fixedly connected to the conveying pipe. A second motor is fixedly connected to the fixing plate, and the output shaft of the second motor is fixedly connected to a lead screw via a coupling. A push rod for preventing material blockage in the hopper is threaded onto the lead screw.

[0006] Optionally, a protective sleeve is also included, wherein the lead screw sleeve is provided with a protective sleeve to prevent debris from affecting the movement of the lead screw.

[0007] Optionally, it also includes a dust cover, which is snapped onto the feed inlet to prevent debris from entering the conveying pipe.

[0008] Optionally, it also includes a handle, which is fixedly connected to the front of the delivery pipe.

[0009] Optionally, it also includes magnets, with magnets for fixing the slider fixedly connected to the left and right ends of the slide.

[0010] The beneficial effects of this utility model are as follows: 1. By putting the metal sheet to be processed into the feed port, the rotation of the spiral tube driven by the first motor will push the metal sheet to the right along the conveying pipe, so that the metal sheet will slide into the feed port at the top of the furnace along the hopper, thereby realizing automatic feeding and avoiding the danger of manually adding materials directly next to the high-temperature furnace.

[0011] 2. The second motor drives the lead screw to rotate, causing the push rod to move up and down, thereby clearing the blockage of metal pieces in the hopper, ensuring smooth feeding, and improving the stability and continuity of feeding.

[0012] 3. The protective sleeve effectively prevents foreign objects from entering the lead screw, ensuring its normal operation and extending its service life. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Example: A feeding device for a gold melting machine, such as Figure 1-4As shown, the device includes a controller 1, a furnace 2, a mounting base 3, a connecting plate 4, a hopper 5, a conveying pipe 6, a first motor 7, a feed inlet 8, a spiral pipe 9, an operating switch 10, and a slider 11. The furnace 2 for melting gold is fixedly connected to the controller 1. The mounting base 3 is fixedly connected to the controller 1. The mounting base 3 has a groove 111, and the slider 11 is slidably connected within the groove 111. The connecting plate 4 is fixedly connected to the slider 11, and the hopper 5 is fixedly connected to the connecting plate 4. The hopper 5 is wedge-shaped, with the left side higher than the right. The right outlet of the hopper 5 is located at... At the top of the furnace 2, the connecting plate 4 is fixedly connected to the conveying pipe 6, the left side of the conveying pipe 6 is fixedly connected to the first motor 7, the top of the conveying pipe 6 is fixedly connected to the feed port 8, the inside of the conveying pipe 6 is rotatably connected to the spiral tube 9 for feeding, and the output shaft of the first motor 7 is fixedly connected to the spiral tube 9 through a coupling. The front of the conveying pipe 6 is fixedly connected to the operating switch 10, which is electrically connected to the first motor 7. It also includes a magnet 19, and the left and right ends of the slide groove 111 are fixedly connected to the magnets 19 for fixing the slider 11.

[0020] When using the feeding device of the gold melting machine, first turn on the power and turn on the operation switch 10. The first motor 7 starts to work. The first motor 7 drives the spiral tube 9 in the conveying pipe 6 to rotate through the coupling. At this time, the metal sheet to be processed is put into the feed port 8. The rotation of the spiral tube 9 will push the metal sheet to move to the right along the conveying pipe 6. Since the feeding hopper 5 is wedge-shaped with the left side higher than the right side, when the metal sheet is conveyed to the position of the feeding hopper 5, under the action of gravity, the metal sheet will slide into the feed port 8 at the top of the furnace 2 along the feeding hopper 5, thereby realizing automatic feeding and avoiding the danger of manual feeding next to the high temperature furnace 2. When it is necessary to adjust the position of the feeding hopper 5, it can be achieved by moving the slider 11. The slider 11 slides within the groove 111 of the mounting base 3, thereby driving the connecting plate 4, the hopper 5, and the conveying pipe 6 connected thereto to move. When the slider 11 moves to a suitable position, the magnets 19 at both ends of the groove 111 will fix the slider 11 to prevent it from moving randomly.

[0021] like Figure 1 and Figure 4As shown, it also includes a fixed plate 12, a second motor 13, a lead screw 14, and a push rod 15. The fixed plate 12 is fixedly connected to the conveying pipe 6, and the second motor 13 is fixedly connected to the fixed plate 12. The output shaft of the second motor 13 is fixedly connected to the lead screw 14 through a coupling. The push rod 15 for preventing material blockage in the hopper 5 is threaded onto the lead screw 14. It also includes a dust cover 17. The dust cover 17 for preventing debris from entering the conveying pipe 6 is snapped onto the feed inlet 8. It also includes a protective sleeve 16. The protective sleeve 16 for preventing debris from affecting the movement of the lead screw 14 is fitted onto the lead screw 14. The protective sleeve 16 is made of rubber telescopic material. It also includes a handle 18. The handle 18 for easy pushing of the device is fixedly connected to the front of the conveying pipe 6.

[0022] If the hopper 5 becomes clogged during the feeding process, the second motor 13 is activated, which drives the lead screw 14 to rotate. Since the top rod 15 is threadedly connected to the lead screw 14, the rotation of the lead screw 14 causes the top rod 15 to move up and down, thereby clearing the blockage of the metal sheet in the hopper 5 and ensuring smooth feeding. The protective sleeve 16 can effectively prevent debris from entering the lead screw 14 and ensure the normal movement of the lead screw 14. The dust cover 17 can prevent debris from entering the conveying pipe 6 from the feed inlet 8, avoiding interference with the feeding process. When it is necessary to move the entire feeding device, the device can be easily pushed to the desired position by holding the handle 18 at the front of the conveying pipe 6.

[0023] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
