[0002] When the galvanizing production line is producing steel pipes, in order to ensure constant temperature and stabilize the amount of zinc applied at 300g, the team will add zinc manually from time to time to keep the temperature in the pot constant. On average, 6-8 bags of zinc are added per shift, and under normal circumstances, 10-20 pieces are added each time. If a car breaks down and the temperature in the pot rises sharply, a whole bag of zinc or more needs to be added each time to lower the temperature in the pot to reach a normal temperature value before production can begin.

The problem exposed was that this operation had great safety hazards, because each piece of zinc weighed about 20 kilograms and could not be thrown in from a distance. If it was thrown in close, the splashed zinc liquid could easily scald the workers and cause work-related injuries. Each shift had to add 6-8 packages of zinc, each package had 54 pieces, and each package weighed more than 1 ton, and the labor intensity was also very high. Therefore, those skilled in the art provided an automatic zinc ingot adding device for hot-dip galvanizing production line to solve the problems raised in the above background technology.

[0023] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0024] Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed by the present invention are not limited to any implementation. In addition, some aspects disclosed by the present invention can be used alone or in any appropriate combination with other aspects disclosed by the present invention.

[0025] Combination Figure 1-6 The example of the hot-dip galvanizing production line zinc ingot automatic adding device is designed to automatically feed zinc blocks. To achieve this purpose, the present invention proposes a hot-dip galvanizing production line zinc ingot automatic adding device, which drives the clamping mechanism 4 to clamp the zinc blocks through two transmission mechanisms 5, and uses an external suspension device to hoist the piled zinc blocks to the zinc storage box 11, the clamping mechanism 4 places the zinc blocks in the zinc storage box 11, the first oil cylinder 24 pushes the pressing plate 25 to push and align the piled zinc blocks, and then the second oil cylinder 31 pushes the top plate 32 to reciprocate, and pushes the piled zinc blocks one by one through the ejection groove 101 into the raw material heating pot, so as to realize automatic zinc addition, and no manual feeding is required, which saves manpower.

[0026] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the automatic zinc ingot adding device for hot-dip galvanizing production line is especially used in galvanizing production line, and comprises: a bottom plate 1, a zinc storage box 11, a controller 12, an alignment mechanism 2 and a feeding mechanism 3.

[0027] The bottom plate 1 is arranged on a placement surface and supported by equipment, and one end of the bottom plate is close to the feeding end of the raw material heating pot.

[0028] Furthermore, a zinc storage box 11 and a controller 12 are provided on the bottom plate 1. The zinc storage box 11 is fixed on the top surface of the bottom plate 1 close to one end of the raw material heating pot and is used to store zinc blocks. An avoidance groove 102 is provided at one end of the zinc storage box 11 away from the raw material heating pot. An ejection groove 101 for feeding zinc blocks is provided at the bottom end of the zinc storage box 11. The controller 12 is arranged on one side of the bottom plate 1 and is used to control the operation of the equipment.

[0029] In an optional embodiment, the base plate 1 and the zinc storage box 11 can both be made of high-strength carbon steel, so that the strength and wear resistance of the base plate 1 and the zinc storage box 11 can meet the use requirements, and the zinc block will not be damaged when sliding, rubbing or colliding on the base plate 1 and the zinc storage box 11. The depth of the avoidance groove 102 can be 1 / 2 of the overall height of the zinc storage box 11, which will not affect the normal operation of the alignment mechanism 2. The height of the ejection groove 101 is the same as the height of the zinc block, ensuring the smooth sliding of the zinc block in the ejection groove 101. The controller 12 is an existing control device used in cylinder control, which controls the first cylinder 24 and the second cylinder 31.

[0030] Furthermore, an alignment mechanism 2 for aligning the zinc blocks in the zinc storage box 11 is installed on one side of the zinc storage box 11 close to the avoidance groove 102. The alignment mechanism 2 includes two support plates 21 and support rods 22 for support. The two support plates 21 are symmetrically fixed on both sides of the zinc storage box 11. The two support rods 22 are fixed between the two support plates 21. A placement plate 23 for installing a first oil cylinder 24 is fixedly connected to the support rod 22. The first oil cylinder 24 is fixed on the top surface of the placement plate 23 and is used to drive a pressure plate 25 to reciprocate. The pressure plate 25 slides inside the zinc storage box 11 and is used to push the zinc blocks to align. The telescopic end of the first oil cylinder 24 passes through the avoidance groove 102 and is fixedly connected to the pressure plate 25.

[0031] In an optional embodiment, the support plate 21, the support rod 22 and the placement plate 23 can all be made of high-strength stainless steel, which not only ensures the supporting strength, but is also not prone to rust and has a long service life. The first oil cylinder 24 can adopt an engineering hydraulic cylinder with a model number of (HSG-L-63*32*300-E1511), and its installation size, stroke and thrust all meet the use requirements. The pressure plate 25 can be made of rigid carbon steel, so that the strength and wear resistance of the pressure plate 25 can meet the use requirements. When pushing the piles of zinc blocks, it ensures the flatness of the piles of zinc blocks and has a long service life.

[0032] In this way, the output end of the first oil cylinder 24 on the placement plate 23 passes through the avoidance groove 102 to push and pull the pressing plate 25, and the pressing plate 25 pushes and aligns the piled zinc blocks to ensure that the zinc blocks fall neatly when being pushed.

[0033] Furthermore, a feeding mechanism 3 for gradually pushing the zinc blocks in the zinc storage box 11 for feeding is installed on the top surface of the bottom plate 1. The feeding mechanism 3 includes a second oil cylinder 31 and a top plate 32. The second oil cylinder 31 is fixed on the top surface of the bottom plate 1 and is used to push the top plate 32 to reciprocate. The top plate 32 is fixed to the telescopic end of the second oil cylinder 31 and is used to push the zinc blocks through the ejection groove 101 for feeding. The feeding mechanism 3 also includes a limit switch 321 fixed on the bottom plate 1 for detecting the position of the top plate 32.

[0034] In an optional embodiment, the second oil cylinder 31 can adopt a multi-section cylinder with a model number (TG-2 100 / 60), whose installation size, stroke and thrust all meet the use requirements. The top plate 32 can be made of high-strength carbon steel, so that the strength and wear resistance of the top plate 32 meet the use requirements, while ensuring the stable pushing of the zinc block. The limit switch 321 can adopt a limit switch with a model number (K5-1640DN-01), which is used to detect the retraction position of the top plate 32, and the limit switch 321 is connected to the controller 12 signal.

[0035] In this way, the second oil cylinder 31 on the zinc storage box 11 pushes the top plate 32 to reciprocate, and the top plate 32 pushes the piled zinc blocks of the zinc storage box 11 out one by one through the ejection groove 101 for feeding. When the top plate 32 is detected to be retracted, it hits the limit switch 321, and the limit switch 321 transmits a signal to the controller 12, and the controller 12 controls the second oil cylinder 31 to stop.

[0036] Combination Figure 5 and Figure 6 As shown, a clamping mechanism 4 for feeding zinc blocks is included, and two transmission mechanisms 5 for driving the clamping mechanism 4 to clamp or release are installed on the clamping mechanism 4.

[0037] Furthermore, the clamping mechanism 4 includes a mounting plate 41 and four cantilevers 42 rotatably connected to its four corners and used for suspension, the bottom ends of the cantilevers 42 are fixedly connected with a lever 43 for supporting the zinc block, and the top surface of the mounting plate 41 is fixedly connected with a hanging plate 44 for connecting to an external suspension device.

[0038] In an optional embodiment, the mounting plate 41, the cantilever 42, the lever 43 and the hanging plate 44 can all be made of high-strength carbon steel to ensure the clamping strength. The lever 43 and the cantilever 42 are vertically distributed to clamp the piled zinc blocks.

[0039] Furthermore, the transmission mechanism 5 includes an active plate 51 and a passive plate 53 for driving the two cantilevers 42 to rotate. The active plate 51 and the passive plate 53 are respectively fixed on the two cantilevers 42. A transmission plate 52 for transmission is hinged between the active plate 51 and the passive plate 53. A handle 54 for holding is fixedly connected to one end of the active plate 51 away from the cantilever 42.

[0040] In an optional embodiment, the active plate 51, the transmission plate 52 and the passive plate 53 can all be made of high-strength stainless steel, so that the active plate 51, the transmission plate 52 and the passive plate 53 can stably drive the cantilever 42 to rotate synchronously, and the handle 54 is arranged vertically, and the side personnel rotate the active plate 51 through the handle 54.

[0041] In this way, the active plate 51 is rotated by the handle 54, and the active plate 51 drives the passive plate 53 to rotate synchronously through the transmission plate 52. The active plate 51 and the passive plate 53 synchronously drive the two cantilevers 42 and the gear lever 43 to rotate, thereby achieving the purpose of rapid unhooking and hooking.

[0042] Combination Figure 3 and Figure 4 As shown, guide grooves 103 are provided on both side walls of the zinc storage box 11 , and guide wheels 26 that slide in the guide grooves 103 are rotatably connected to both ends of the pressing plate 25 .

[0043] In an optional embodiment, the length of the guide groove 103 can be 1 / 2 of the width of the zinc storage box 11 to ensure sufficient guide travel. The guide wheel 26 can be made of stainless steel and will not get stuck due to rust when sliding in the guide groove 103.

[0044] In this way, when the pressing plate 25 moves, the guide wheel 26 slides along the guide groove 103 to guide the movement of the pressing plate 25 .

[0045] Furthermore, a bracket 33 for supporting a support roller 34 is fixedly connected to the top surface of the bottom plate 1 . The support roller 34 is rotatably connected to the top end of the bracket 33 and is used to support the sliding of the top plate 32 .

[0046] In an optional embodiment, the bracket 33 may be U-shaped, which can provide good support for the support roller 34. The support roller 34 may be made of high-strength stainless steel, which is not prone to rust and has a long service life while ensuring stable support for the top plate 32.

[0047] In this way, when the top plate 32 moves, the support rollers 34 on the bracket 33 provide auxiliary support to the top plate 32 to ensure the stability of its pushing.

[0048] The working principle of the present invention is: the active plate 51 is rotated by the handle 54, and the active plate 51 drives the passive plate 53 to rotate synchronously through the transmission plate 52, and the active plate 51 and the passive plate 53 synchronously drive the two cantilevers 42 and the gear rod 43 to rotate, and the gear rod 43 rotates to the bottom of the piled zinc blocks to clamp the piled zinc blocks, and then the piled zinc blocks are suspended into the zinc storage box 11 through the external suspension equipment, and then the gear rod 43 is rotated to the outside of the piled zinc blocks, and the clamping mechanism 4 is lifted off as a whole, and the first oil cylinder 24 and the second oil cylinder 31 are controlled by the controller 12, and the output end of the first oil cylinder 24 on the placement plate 23 pushes and pulls the pressing plate 25 through the avoidance groove 102, and the pressing plate 25 pushes and aligns the piled zinc blocks to ensure that the zinc blocks fall neatly when being pushed, and the second oil cylinder 31 on the zinc storage box 11 pushes the top plate 32 to reciprocate, and the top plate 32 pushes the piled zinc blocks of the zinc storage box 11 one by one through the ejection groove 101 for feeding.

[0049] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
