One end of the first support rod 17 is fixed to the side wall of the slip-on plate 9, and the other end of the first support rod 17 passes through the central slotted hole 5 and connects to the fixing plate 18. The fixing plate 18 has openings at both its upper and lower ends. The outer wall of the housing 2 has several positioning holes 19 above and below the central slotted hole 5. The fixing plate 18 is locked to the housing 2 by pins 20 passing through the openings and positioning holes 19. The other end of the fixing plate 18... A second support rod 36 is connected to the second support rod 20. A support frame 21 is connected to the other end of the second support rod 20. A hydraulic cylinder 22 is connected to the support frame 21. A transverse plate 23 is connected to the telescopic end of the hydraulic cylinder 22. Two symmetrically arranged insert rods 24 are connected to the transverse plate 23. The other ends of the two insert rods 24 pass through two sliding holes opened on the support frame 21 and then through two upper and lower strip holes 5 to be placed inside the box body 2. The ends of the insert rods 24 pass through the insertion holes 25 opened on the loose plate 9 and are fixed on the lifting plate 10.

[0028] The top of the two side walls of the box 2 are respectively provided with a discharge port 3 and a feed port 4. The outer side of the discharge port 3 and the feed port 4 are provided with a guide component. The guide component is installed on the outer wall of the box 2. The guide component includes an upper roller 32, a lower roller 33 and a side vertical roller 34 installed on the box 2.

[0029] A workbench 6 is also installed on the base 1 near the feed inlet 4. A locking assembly is installed on the workbench 6. The locking assembly includes a mounting bracket 26 connected to the workbench 6 and a first cylinder 27 installed on the mounting bracket 26. The telescopic end of the first cylinder 27 passes through the mounting bracket 26 and is connected to a pressure plate 28. Several protrusions 29 are provided on the bottom surface of the pressure plate 28 to increase friction.

[0030] An auxiliary conveying assembly is installed on the right side of the locking assembly. The auxiliary conveying assembly includes two adjustable bearing seats 30 mounted on the worktable 6. A conveying roller is installed between the two adjustable bearing seats 30. The conveying roller is controlled to lift and lower by a second cylinder 31 mounted on the adjustable bearing seat 30.

[0031] After passing through the auxiliary conveying assembly and the locking assembly in sequence, the strip steel on the uncoiler is guided by several guide rollers 8 and enters the housing 2. The strip steel is arranged in a wave shape around the fence assembly inside the housing 2. The end of the strip steel passes through the discharge port 3 and is connected to the subsequent equipment. A sensor 7 is installed on the side wall of the workbench 6 near the uncoiler.

[0032] The operation process of this invention is as follows:

[0033] In use, the strip coil is installed on the uncoiler, the box door 35 is opened, and the end of the strip is placed on the worktable 6. The second cylinder 31 drives the conveyor roller to descend and press on the strip. The strip is then conveyed by the friction of the conveyor roller. The strip is then manually controlled to enter the box 2 from the feed port 4, then shuttles between the various grid components, and finally exits from the discharge port 3 to connect to the equipment of the next process. Then, depending on the actual situation, the pin 20 is pulled out, the position of the fixing plate 18 is adjusted, and then it is fixed by the pin 20. The box door 35 is closed, and the second cylinder 31 controls the conveyor roller to reset. Then the equipment of the next process is started, and the strip is pulled by traction force. When the strip coil on the uncoiler has been conveyed, the sensor 7 detects that there is no strip above, and the hydraulic cylinder 2... 2. Immediately control the insertion rod 24 to be pulled out from the insertion hole 25, so that the end of the insertion rod 24 no longer presses against the lifting plate 10. When the strip is being pulled, the upper and lower lifting plates 10 continuously retract into the loop plate 9 due to the tension of the strip, thereby sending out the strip stored inside the box 2. At the same time, the extension end of the first cylinder 27 controls the pressure plate 28 to descend, pressing down the part of the strip on the workbench 6. Then the worker installs a new strip coil and pulls the end of the strip to the end of the previous strip through the auxiliary conveying component for welding. After welding, the first cylinder 27 resets. After a period of strip supply, the tension of the strip on the lifting plate 10 will decrease, and the lifting plate 10 will reset through the spring 13, so that the box 2 stores the strip again due to the change in the height of the fence component.
