Description

Technical Field

[0001] The invention belongs to the technical field of high-precision rolling of aluminum strips by cold rolling mills and processing of aluminum coil remnant coils, and specifically relates to a gantry-type high-precision aluminum strip remnant coil shovel head material guiding device and a remnant coil head feeding method. Background Art

[0002] During the high-precision rolling process of aluminum strip in the cold rolling mill, the last section of the tail coil of the aluminum coil is a substandard material and cannot enter the rolling mill for rolling. This tail coil is called a residual coil and needs to be unfolded, sliced ​​and recycled in a special residual coil station. In the residual coil station, the residual coil is grabbed by the robot and inserted into the reel of the residual coil station unwinder. At this time, the head of the residual coil is close to the residual coil, and a special shovel head device must be used to peel the head. Due to the large elastic modulus of the residual coil aluminum strip and the thick strip, the strip head will not move along the horizontal guide plate after peeling, but will seriously warp up. In order to smoothly send the strip head along the guide plate into the pinch roller of the residual coil station, it is necessary to guide the warped strip head. The current existing equipment and technology cannot achieve this operation. Summary of the invention

[0003] The purpose of the present invention is to provide a gantry type high-precision aluminum strip residual roll shovel head material guiding device to overcome the above-mentioned technical problems existing in the prior art.

[0004] Another object of the present invention is to provide a method for feeding the head of a residual roll, which can accurately peel off the head of the residual roll and feed it into the pinch roller of the residual roll station through the two actions of shoveling head and guiding material.

[0005] To this end, the technical solution provided by the present invention is as follows:

[0006] A gantry type high-precision aluminum strip residual roll shovel head material guiding device comprises a shovel plate mechanism, a shovel head frame, a connecting rod, and a hinge shaft support. The shovel head frames are two and are respectively arranged at the two ends of the shovel plate mechanism. The two ends of the shovel plate mechanism are installed in the shaft holes of the shovel head frame and can rotate freely. The two ends of the shovel plate mechanism are hinged with a shovel plate oil cylinder. The cylinder body of the shovel plate oil cylinder is hinged on the shovel head frame. The bottom of the shovel head frame is hinged on the hinge shaft support. The hinge shaft support is fixed on the external frame.

[0007] There are two connecting rods, which are hinged to one end of the two shovel head frames respectively. The other end of the connecting rod is hinged with a swing arm. The swing arm is symmetrically hinged with two material guiding cylinders. Both ends of the swing arm are hinged with two hinge shaft supports. The two hinge shaft supports are fixed on the external frame. The material guiding cylinder is arranged on the cylinder support, and the cylinder support is fixed on the external frame.

[0008] The shovel mechanism includes a shovel, a shovel seat and a pressure roller. There are two shovel seats, which are fixed at the two ends of the shovel respectively. The pressure roller is arranged in front of the shovel. One end of the two shovel seats is hinged to the two ends of the shaft of the pressure roller respectively, and the other end of the shovel seat is hinged to the cylinder joint of the shovel cylinder. The two ends of the shaft of the pressure roller are installed in the axial holes of the shovel head frame.

[0009] The swing arm includes a long axis, a swing arm 1 and a swing arm 2. There are two swing arms 1 and 2, and both are fixed on the long axis. The two swing arms 1 are respectively arranged at two ends of the long axis, and the two swing arms 2 are arranged between the two swing arms 1 and are symmetrically arranged. The swing arm 1 is hinged to the connecting rod, and the swing arm 2 is hinged to the material guide cylinder.

[0010] The middle of the cylinder body of the material guiding oil cylinder is hinged to the oil cylinder support, and the cylinder body of the material guiding oil cylinder is hinged to two oil cylinder supports.

[0011] A protective plate is fixedly arranged in the middle of the shovel plate. The shovel plate is a wedge-shaped long plate. The shovel head of the shovel plate is a long sharp corner. The protective plate is an L-shaped long plate and a long sharp corner is arranged on the side close to the shovel head.

[0012] The surface of the pressing roller is coated with a polyurethane adhesive layer.

[0013] The included angle between the first swing arm and the second swing arm is 45°-60°.

[0014] A method for feeding a residual coil head, using a gantry type high-precision aluminum strip residual coil shovel head guiding device, comprises the following steps:

[0015] Step 1) After the remnant roll is in place, the piston rod of the guide cylinder extends, the swing arm swings clockwise, and the connecting rod hinged to it moves with the movement, driving the shovel head frame to swing clockwise around the hinged support. When the pressure roller contacts the remnant roll, the guide cylinder stops moving;

[0016] Step 2) Retract the piston rod of the scraper cylinder, driving the scraper seat and the scraper plate hinged therewith to swing counterclockwise around the axis of the pressure roller. When the sharp corner of the scraper plate head fits the residual roll, the scraper cylinder stops moving;

[0017] Step 3) Drive the unwinder to rotate the residual roll drum clockwise. When the tape head close to the residual roll contacts the scraper, the scraper separates the tape head from the residual roll. Then the piston rod of the scraper cylinder extends, and the scraper seat swings clockwise, driving the scraper to fall.

[0018] Step 4) Retract the piston rod of the guide cylinder, and the swing arm swings counterclockwise. The connecting rod hinged thereto moves with the movement, driving the shovel head frame to swing counterclockwise around the hinged support. At this time, the shovel plate and the protective plate press the upturned belt head. As the shovel plate and the protective plate fall counterclockwise, the belt head is guided to a horizontal position. When the belt head is guided to the horizontal guide plate 18, the guide cylinder stops moving;

[0019] Step 5) The remnant roll continues to rotate clockwise to feed the tape head into the subsequent pinch rollers, completing the feeding of the remnant tape head.

[0020] Before the residual roll is in place, the piston rod of the material guide cylinder retracts, causing the pressure roller to move away from the winding machine drum, the piston rod of the shovel cylinder extends, and the shovel is in the dropped position.

[0021] One end of the horizontal guide plate is located below the reel, and the other end is connected to the pinch roller.

[0022] The beneficial effects of the present invention are:

[0023] The gantry type high-precision aluminum strip residual roll shovel head material guiding device provided by the present invention has all connection and driving components except the swing arm distributed on both sides of the device. The gantry structure avoids the middle guide plate and feeding channel, and the entire device is compactly arranged.

[0024] A protective plate is set on the shovel to prevent the shovel from being damaged by the belt head; a polyurethane adhesive layer is coated on the pressure roller to prevent the belt from slipping.

[0025] The invention has a delicate structure and can accurately peel off the tape head of the residual roll and send it to the pinch roller of the residual roll station through the two actions of the shovel head and the material guiding, and has a good application and promotion prospect.

[0065] When the remnant roll 16 is in place, the piston rod of the guide cylinder 11 is extended, the swing arm 10 swings clockwise, and the connecting rod 8 articulated therewith moves, driving the shovel head frame 5 to swing clockwise around the articulated support.

When the strip head 17 is guided to the horizontal guide plate 18, the guide cylinder 11 stops moving, as shown in FIG. Figure 3 As shown, the unwinder drum continues to rotate clockwise to feed the tape head 17 into the subsequent pinch rollers, and the feeding operation of the entire residual roll 16 is completed.

[0067] Embodiment 8:

[0068] This embodiment provides a method for feeding a residual roll head, comprising the following steps:

[0069] Step 1) After the remnant roll 16 is in place, the piston rod of the guide cylinder 11 extends, the swing arm 10 swings clockwise, and the connecting rod 8 hinged thereto moves along with it, driving the shovel head frame 5 to swing clockwise around the hinged support. When the pressure roller 4 contacts the remnant roll 16, the guide cylinder 11 stops moving;

[0070] Step 2) Retract the piston rod of the shovel plate oil cylinder 6, driving the shovel plate seat 1 and the shovel plate 2 hinged thereto to swing counterclockwise around the axis of the pressure roller 4. When the tip of the shovel plate 2 fits the residual roll 16, the shovel plate oil cylinder 6 stops moving;

[0071] Step 3) The unwinder is driven to rotate the reel of the residual roll 16 clockwise. When the belt head 17 close to the residual roll 16 contacts the scraper plate 2, the scraper plate 2 separates the belt head 17 from the residual roll 16. Then, the piston rod of the scraper plate oil cylinder 6 extends, and the scraper plate seat 1 swings clockwise, driving the scraper plate 2 to fall.

[0072] Step 4) Retract the piston rod of the material guide cylinder 11, and the swing arm 10 swings counterclockwise. The connecting rod 8 hinged thereto moves with the movement, driving the shovel head frame 5 to swing counterclockwise around the hinged support. At this time, the shovel plate 2 and the protective plate 3 press the upturned belt head 17. As the shovel plate 2 and the protective plate 3 fall counterclockwise, the belt head 17 is guided to a horizontal position. When the belt head 17 is guided to the horizontal guide plate 18, the material guide cylinder 11 stops moving;

[0073] Step 5) The reel of the residual roll 16 continues to rotate clockwise to feed the tape head 17 into the subsequent pinch rollers, thus completing the feeding of the entire residual roll 16 with the tape head 17.

[0074] Before the residual roll 16 is in place, the piston rod of the material guide cylinder 11 is retracted, so that the pressure roller 4 is far away from the winding machine drum, the piston rod of the shovel plate cylinder 6 is extended, and the shovel plate 2 is in the dropped position.

[0075] One end of the horizontal guide plate 18 is located below the reel, and the other end is connected to the pinch roller.

When the pressure roller (4) contacts the residual roll (16), the guide cylinder (11) stops moving; Step 2) retracting the piston rod of the shovel plate oil cylinder (6), driving the shovel plate seat (1) and the shovel plate (2) hinged thereto to swing counterclockwise around the axis of the pressure roller (4); when the tip of the shovel plate (2) fits the residual roll (16), the shovel plate oil cylinder (6) stops moving; Step 3) driving the unwinder to rotate the reel of the residual roll (16) clockwise, and when the belt head (17) closely attached to the residual roll (16) contacts the scraper plate (2), the scraper plate (2) separates the belt head (17) from the residual roll (16), and then the piston rod of the scraper plate oil cylinder (6) extends, and the scraper plate seat (1) swings clockwise, driving the scraper plate (2) to fall; Step 4) The piston rod of the guide cylinder (11) is retracted, and the swing arm (10) swings counterclockwise. The connecting rod (8) hinged thereto moves with the movement, driving the shovel head frame (5) to swing counterclockwise around the hinge shaft support (7). At this time, the shovel plate (2) and the protective plate (3) press the upwardly tilted belt head (17). As the shovel plate (2) and the protective plate (3) fall counterclockwise, the belt head (17) is guided to a horizontal position. When the belt head (17) is guided to the horizontal guide plate (18), the guide cylinder (11) stops moving; Step 5) The reel of the remaining roll (16) continues to rotate clockwise to feed the tape head (17) into the subsequent pinch rollers, thus completing the feeding of the entire remaining roll (16) with the tape head (17).

7. A method for feeding a residual roll head according to claim 6, characterized in that: Before the residual roll (16) is in place, the piston rod of the material guide cylinder (11) is retracted, so that the pressure roller (4) is far away from the winding machine drum, and the piston rod of the shovel plate cylinder (6) is extended, and the shovel plate (2) is in the dropped position.

8. A method for feeding a residual roll head according to claim 6, characterized in that: One end of the horizontal guide plate (18) is located below the reel, and the other end is connected to the pinch roller.
