[0004] In the above-mentioned comparative patent, the copper rod needs to be placed on the loading platform first, and then the loading platform is driven to rise by the loading cylinder, and finally the copper rod on the loading platform is rolled into the copper rod heating furnace. However, because the weight of the copper rod is very heavy, it is inconvenient to place the copper rod on the loading platform. At the same time, the force required by the loading cylinder to drive the loading platform (with multiple copper rods) is large, resulting in the loading cylinder being in a high-load state for a long time, and thus easily damaged during use. Utility Model Content

[0005] The utility model aims to provide an automatic feeding device for a copper rod heating furnace, which has the function of conveniently conveying the copper rods into the copper rod heating furnace.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an automatic feeding device for a copper rod heating furnace, comprising a mounting groove arranged on the ground below the entrance of the copper rod heating furnace, a support frame arranged on one side of the entrance of the copper rod heating furnace and with the lower end located in the mounting groove, a driving shaft rotatably arranged at the lower end of the support frame, a reduction motor arranged on the support frame and linked to the driving shaft, a driven shaft rotatably connected to the upper end of the support frame, two driving sprockets arranged on the driving shaft, two driven sprockets arranged on the driven shaft, two chains arranged between the corresponding driving sprockets and the driven sprockets, two supporting hooks arranged on the chains, a first inclined track arranged on one side of the mounting groove and guiding the copper rod to roll to the two supporting hooks under the action of gravity, and a second inclined track arranged on the support frame and allowing the copper rod from the supporting hooks to roll to the entrance of the copper rod heating furnace under the action of gravity.

[0007] The utility model is further configured as follows: an inclined groove is provided on the ground, which is connected to one side of the installation groove and is used for installing a first inclined rail; one end of the first inclined rail away from the installation groove is flush with the ground; one end of the first inclined rail located in the installation groove is provided with a baffle to prevent the copper rod from rolling down and not interfering with the movement of the supporting hook; a first notch is provided between the first inclined rails which does not affect the upward movement of the two supporting hooks following the chain; and the supporting hook lifts the copper rod close to the baffle upward during the upward movement.

[0008] The utility model is further configured as follows: a buffer component is arranged on the inner side of the baffle.

[0009] The utility model is further configured as follows: the buffer assembly includes a buffer plate, a plurality of guide shafts arranged on the buffer plate and passing through the baffle plate, a compression spring sleeved on the guide shaft and with both ends pressed against between the baffle plate and the buffer plate, and an anti-slip nut arranged at one end of the guide shaft passing through the baffle plate.

[0010] The utility model is further configured as follows: a second notch is provided on the second inclined track which does not affect the movement of the two supporting hooks following the chain; recessed portions extending along the length direction of the second inclined track are provided on both sides of the second inclined track; a hinge shaft is provided in the recessed portion with one end hinged to an end of the recessed portion close to the copper rod heating furnace; a driving cylinder for driving the hinge shaft to rotate is hingedly provided between the other end of the hinged shaft and the support frame.

[0011] In summary, the beneficial effects of the utility model are:

[0012] 1. When the copper rods are automatically fed into the copper rod heating furnace, a plurality of copper rods are first arranged and piled on the first inclined track. As the reduction motor drives the chain to rotate, the hook on the chain can lift the copper rod closest to the installation slot upward. The copper rod flips onto the second inclined track after the hook moves upward. The copper rod automatically rolls along the second inclined track into the copper rod heating furnace, which facilitates the transportation of the copper rods into the copper rod heating furnace.

[0013] 2. Because the copper rod on the first inclined track rolls onto the two hooks under the action of gravity, when the hook carries the first copper rod upward, the next copper rod will remain in contact with the sides of the two chains; at this time, the baffle plate on the first inclined track separates the first copper rod in the first inclined track from the chain, thereby reducing the resistance of the chain when it is running, and the first notch can avoid affecting the movement of the hook;

[0014] 3. By setting a buffer component, when the previous copper rod is lifted upward by the support hook, the subsequent copper rods can be elastically buffered during the rolling process, thereby reducing the force on the baffle;

[0015] 4. When the copper rod rolls on the second inclined track, the rolling is sometimes hindered due to friction. At this time, the recessed portion, the hinge shaft and the driving cylinder are arranged so that the driving cylinder drives the hinge shaft to rotate upward, thereby lifting the copper rod and making it easier for the copper rod to roll into the copper rod heating furnace.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment: An automatic feeding device for a copper rod heating furnace, such as Figure 1 and Figure 2 As shown, it includes a mounting groove 1 arranged on the ground below the entrance of the copper rod heating furnace, a support frame 2 arranged at one side of the entrance of the copper rod heating furnace and with the lower end located in the mounting groove 1, a driving shaft 3 rotatably arranged at the lower end of the support frame 2, a reduction motor 4 arranged on the support frame 2 and linked with the driving shaft 3, a driven shaft 5 rotatably connected to the upper end of the support frame 2, two driving sprockets 6 arranged on the driving shaft 3, two driven sprockets 7 arranged on the driven shaft 5, two chains 8 arranged between the corresponding driving sprockets 6 and the driven sprockets 7, two hooks 9 arranged on the chains 8, a first inclined track 10 arranged at one side of the mounting groove 1 and guiding the copper rod to roll onto the two hooks 9 under the action of gravity, and a second inclined track 11 arranged on the support frame 2 and allowing the copper rod from the hooks 9 to roll into the entrance of the copper rod heating furnace under the action of gravity.

[0023] like Figure 2 and Figure 3 As shown, an inclined groove 12 is provided on the ground, which is connected to one side of the installation groove 1 and is used for installing the first inclined rail 10. The end of the first inclined rail 10 away from the installation groove 1 is flush with the ground. The end of the first inclined rail 10 located in the installation groove 1 is provided with a baffle 13 for preventing the copper rod from rolling down and not interfering with the movement of the hook 9. A first notch 101 is provided between the first inclined rails 10 which does not affect the upward movement of the two hooks 9 following the chain 8. The hook 9 can lift the copper rod close to the baffle 13 upward during the upward movement.

[0024] like Figure 3 As shown, a buffer assembly 14 is provided inside the baffle 13. The buffer assembly 14 includes a buffer plate 141, a plurality of guide shafts 142 provided on the buffer plate 141 and passing through the baffle 13, a compression spring 143 sleeved on the guide shaft 142 and with both ends pressed between the baffle 13 and the buffer plate 141, and an anti-drop nut 144 provided at one end of the guide shaft 142 passing through the baffle 13.

[0025] like Figure 2 and Figure 4 As shown, the second inclined rail 11 is provided with a second notch 111 which does not affect the movement of the two hooks 9 following the chain 8, and both sides of the second inclined rail 11 are provided with recessed portions 112 extending along its length direction, and the recessed portion 112 is provided with an articulated shaft 15 with one end hinged to one end of the recessed portion 112 close to the copper rod heating furnace, and a driving cylinder 16 for driving the articulated shaft 15 to rotate is hingedly provided between the other end of the articulated shaft 15 and the support frame 2.

[0026] Implementation effect: When the copper rods are automatically fed into the copper rod heating furnace, a plurality of copper rods are first arranged and piled on the first inclined track 10. As the reduction motor 4 runs and drives the chain 8 to rotate, the hook 9 on the chain 8 can lift the copper rod closest to the mounting groove 1 upward. After the hook 9 moves upward, the copper rod flips onto the second inclined track 11. The copper rod automatically rolls along the second inclined track 11 into the copper rod heating furnace, which facilitates the transportation of the copper rods into the copper rod heating furnace.

[0027] Because the copper rod on the first inclined track 10 rolls onto the two hooks 9 under the action of gravity, when the hooks 9 carry the previous copper rod upward, the next copper rod will remain in a state of contacting the sides of the two chains 8; at this time, the baffle 13 on the first inclined track 10 is set so that the first copper rod in the first inclined track 10 is separated from the chain 8, thereby reducing the resistance of the chain 8 when it is running, and the setting of the first notch 101 can avoid affecting the movement of the hook 9. By setting the buffer component 14, when the previous copper rod is lifted upward by the hook 9, the subsequent copper rod can be elastically buffered during the rolling process, thereby reducing the force on the baffle 13. When the copper rod rolls on the second inclined track 11, the rolling is sometimes blocked due to friction. At this time, by setting the recessed portion 112, the hinge shaft 15 and the driving cylinder 16, the driving cylinder 16 drives the hinge shaft 15 to rotate upward, thereby lifting the copper rod, which is convenient for the copper rod to roll into the copper rod heating furnace.

[0028] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
