Description

Technical Field

[0001] The invention relates to the technical field of uncoilers, and in particular to a cone sleeve type uncoiler drum structure. Background Art

[0002] The steel coil uncoiler is a special equipment for conveying metal sheets. When uncoiling, a special trolley is used to lift the steel coil onto the saddle of the uncoiler. The coiling trolley automatically aligns the height (coil diameter measurement) and delivers the steel coil to the material shaft. Then the movable support is closed, the pressure roller is lowered, and the coiling trolley is lowered and returned. The motor drives the material shaft to rotate and delivers the head of the strip into the leveling machine or subsequent processing equipment. During the whole process, a special trolley is required to assist in the handling, which is quite inconvenient. When the workshop only has a crane, it is quite difficult to lift the steel coil to the designated position, which is easy to cause damage to the uncoiler; in addition, when driving a special trolley, it is necessary to have certain driving experience to arrange the material coil coaxially on the material shaft more accurately, and the operation process is quite inconvenient.

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] like Figure 1-Figure 8The shown pyramid sleeve uncoiler reel structure comprises a base frame 1, the upper surface of the base frame 1 is connected to a lifting frame 2 through a lifting mechanism, a concave frame 14 is fixedly installed on one side of the upper surface of the lifting frame 2, the upper surface of the concave frame 14 is connected to two rotating shafts 10 through a distance adjustment mechanism, one end of the rotating shaft 10 is fixedly connected to a rotating rod 8, a spiral strip 9 is fixedly embedded on the outer surface of the rotating rod 8, the other end of the rotating shaft 10 is fixedly connected to a friction roller 12, a transmission belt 20 is installed on one side surface of the concave frame 14 through a driving mechanism, the friction roller 12 contacts the upper surface of the transmission belt 20, a connecting plate 21 is fixedly installed at the front end of the base frame 1, a vertical bracket 22 is fixedly connected to the upper surface of the connecting plate 21, a conveying mechanism is arranged at the upper end of the vertical bracket 22, and a material roller mechanism is fixedly connected to the rear surface of the vertical bracket 22.

[0026] like Figure 3 As shown, the lifting mechanism includes a bottom fixing plate 3 fixedly mounted in the middle of the upper surface of the bottom frame 1, a lifting cylinder 4 fixedly mounted on the upper surface of the bottom fixing plate 3, the telescopic end of the lifting cylinder 4 fixedly connected to the lower surface of the lifting frame 2, a guide cylinder 5 fixedly mounted at the corner of the upper surface of the bottom frame 1, a guide column 6 slidably inserted at the upper end of the guide cylinder 5, and the upper end of the guide column 6 fixedly connected to the lower surface of the lifting frame 2. By controlling the extension and contraction of the lifting cylinder 4, the lifting frame 2 moves up and down, and the guide column 6 slides up and down relative to the inner side of the guide cylinder 5 to ensure the stability of the lifting frame 2 during lifting.

[0027] like Figure 2 , Figure 4 As shown, the pitch adjustment mechanism includes two pitch adjustment plates 11 slidably connected to the inner side of the concave frame 14, one end of each rotating shaft 10 rotates through the side surface of the pitch adjustment plate 11, and a screw rod 13 is rotatably installed on the inner side of the concave frame 14. The screw rod 13 threads through the surfaces of the two pitch adjustment plates 11, and the rear end of the screw rod 13 is fixedly connected to the output shaft of the first motor 15, and the first motor 15 is fixedly installed on the rear surface of the concave frame 14. The surface threads of the screw rod 13 are symmetrical in front and back, ensuring that when the screw rod 13 rotates, the two pitch adjustment plates 11 will move relatively close or away.

[0028] like Figure 2 As shown, one end of the rotating rod 8 away from the rotating shaft 10 is rotatably connected to the sliding frame 7, and the lower end of the sliding frame 7 is slidably mounted on the upper surface of the lifting frame 2. The sliding frame 7 supports one end of the rotating rod 8, thereby ensuring the stability of the rotating rod 8 when moving.

[0029] like Figure 4As shown, the driving mechanism includes a side frame 16 fixedly mounted on one side of the concave frame 14, a plurality of rotating rollers 17 are arranged on the inner side of the side frame 16, and roller shafts 18 are fixedly connected to both ends of the rotating rollers 17, and the roller shafts 18 rotate and penetrate the inner side of the concave frame 14, and one end of the rearmost roller shaft 18 is fixedly connected to the output shaft of the second motor 19, and the second motor 19 is fixedly mounted on one side surface of the side frame 16, and the transmission belt 20 is sleeved on the outer surface of the plurality of rotating rollers 17.

[0031] like Figure 5 As shown, the material roller mechanism includes a fixing frame 27 fixedly mounted on the rear surface of the vertical bracket 22, one side of the fixing frame 27 is rotatably connected to a material shaft 28, the outer surface of the material shaft 28 is provided with two pyramid sleeves 29 through a locking sleeve, and the outer surface of the pyramid sleeve 29 is fixedly provided with a limit plate 30. The limit plate 30 plays a limiting role to prevent the steel coil from deviating to both sides.

[0032] like Figure 5 , Figure 6 , Figure 7 As shown, the locking member includes a positioning bolt 32 threadedly inserted into the outer surface of the pyramid sleeve 29, a key bar 31 is fixedly installed on the outer surface of the material shaft 28, and the key bar 31 is embedded in the inner surface of the pyramid sleeve 29, ensuring that the material shaft 28 can drive the pyramid sleeve 29 to rotate synchronously, thereby causing the steel coil to rotate at the same time.

[0033] When in use, first unscrew the positioning bolt 32 on one side of the pyramid sleeve 29, remove the pyramid sleeve 29, then hoist the steel sheet material roll to the surface of the two rotating rods 8, and then control the second motor 19 to operate, so that the rotating roller 17 rotates, thereby moving the transmission belt 20, driving the friction roller 12 to rotate, and then the two rotating shafts 10 rotate synchronously, and the rotating rod 8 rotates to rotate the material roll, and cooperates with the guidance of the spiral strip 9 to make the material roll rotate while moving toward one side of the material shaft 28 until it moves to the outside of the material shaft 28, and then stop the second motor 19, and install the removed pyramid sleeve 29 again, so that the arrangement of the material roll is completed. Figure 8 As shown, therefore, it can assist in the rapid arrangement of large coils during uncoiling and reduce the difficulty of operation.

[0034] The user controls the first motor 15 to rotate, so that the screw rod 13 rotates, and then the two distance adjusting plates 11 move closer to or away from each other, changing the distance between the two rotating rods 8, thereby ensuring that the material roll can be lifted at an appropriate distance, and then cooperating with the extension and retraction of the lifting cylinder 4 to move the lifting frame 2 up and down, thereby changing the height of the two rotating rods 8, ensuring that when the distance between the rotating rods 8 is changed, the height of the material roll can be adjusted, ensuring that the material roll and the material shaft 28 remain coaxial, ensuring subsequent assistance in loading, and having good adaptability and flexible use.
