Description

Technical Field

[0001] This application relates to the field of slitting machine technology, and in particular to a feeding device for a slitting machine. Background Technology

[0002] To facilitate the storage and transportation of steel, it is generally hot-pressed or cold-pressed into coils. When the steel coils are needed for subsequent production, they must be straightened to allow for various processing steps, such as turning them into steel plates or strips. Most manufacturers use leveling machines for this straightening process; leveling machines are machines that perform a series of processing operations on metal sheets, including uncoiling, leveling, and shearing.

[0003] A slitting machine, also known as an uncoiling and leveling machine or an uncoiling and leveling production line, comprises an uncoiler, a leveler, a shearing machine, and a stacker. The uncoiler drives the steel coil to rotate and unwind it. After unwinding, the steel enters the leveler, which repeatedly rolls the steel to stabilize its curvature and straighten it. The straightened steel then moves to the shearing machine, which cuts it into the required length. Finally, the stacker piles the cut steel together.

[0004] During the operation of the sizing machine, the uncoiler needs to be loaded first. When loading, the operator first uses a forklift to place the steel coil onto the loading trolley. Then the loading trolley moves upward so that the center of the steel coil is coaxial with the drum shaft. Next, the loading trolley moves towards the side closer to the drum shaft to place the steel coil onto the drum shaft. Then the loading trolley moves downward and away from the drum shaft to complete the loading process.

[0005] Whenever the steel coils on the drum are used up, the loading trolley moves the steel coils on the table to the drum. Then, the operator needs to use a forklift to move the steel coils onto the loading trolley. Therefore, during the operation of the sizing machine, the operator needs to intermittently move the steel coils onto the loading trolley. If the operator delivers the steel coils too early, they will have to wait until the steel coils on the drum are used up before they can put the steel coils onto the loading trolley, which wastes time. If the operator arrives too late, it will cause the sizing machine to be down for too long, affecting production efficiency. Therefore, intermittent loading makes the operator's work inconvenient. Summary of the Invention

[0006] To make the feeding process continuous and simpler, this application provides a feeding device for a leveling machine.

[0007] The feeding device for a leveling machine provided in this application adopts the following technical solution:

[0008] A feeding device for a leveling machine includes a feeding trolley disposed on one side of a drum shaft. A support plate is disposed on the side of the feeding trolley away from the drum shaft. A first telescopic member for driving the support plate to move is disposed on one side of the support plate. The telescopic direction of the first telescopic member is perpendicular to the axis of the drum shaft. A placement seat for placing steel coils is disposed on the support plate. Multiple placement seats are disposed in both directions parallel to and perpendicular to the axis of the drum shaft. The axis of the steel coil placed on the placement seat is parallel to the axis of the drum shaft. A pushing component is disposed on one side of the support plate. The pushing component is used to push the steel coils on the support plate that are in the same straight line as the steel coils on the feeding trolley to move toward the side closer to the feeding trolley.

[0009] By adopting the above technical solution, in the initial state, a row of steel coils placed on the support plate and a row of steel coils placed on the loading trolley are coaxial. After the loading trolley moves the steel coils onto the drum shaft, it moves back to its original position. Then, the pushing component moves the steel coils on the support plate, pushing them onto the loading trolley and forward a distance for easy loading onto the trolley next time. After all the steel coils coaxial with those on the loading trolley have been removed, the first telescopic component pushes the support plate, moving the next row of steel coils on the support plate to a position coaxial with those on the loading trolley, facilitating the pushing component to load them onto the trolley. Therefore, only multiple steel coils need to be placed on the support plate, and the pushing component can automatically push them onto the loading trolley, thus achieving automatic loading over a longer period without the need for intermittent loading by operators, making the loading process more convenient.

[0010] Optionally, the pushing assembly includes a second telescopic member disposed on one side of the support plate, a third telescopic member disposed on the movable end of the second telescopic member, and a push plate disposed on the movable end of the third telescopic member. The telescopic direction of the second telescopic member is perpendicular to the axial direction of the drum shaft, and the telescopic direction of the third telescopic member is parallel to the axial direction of the drum shaft. Multiple push plates are provided and are spaced apart along the length direction of the third telescopic member at the movable end of the third telescopic member. The number of push plates is the same as the maximum number of placement seats disposed on the support plate along the axial direction of the drum shaft.

[0011] By adopting the above technical solution, the third telescopic component drives the push plate to move, and the push plate can push the steel coil to move along its own length direction, thereby moving the steel coil from the bearing plate to the loading trolley. The movement process of the steel coil is simple, stable and reliable.

[0012] Optionally, the movable end of the third telescopic member is provided with multiple through holes at intervals along its own telescopic direction, and a connecting bolt is connected between the push plate and the through holes, and a connecting nut is threaded onto the connecting bolt.

[0013] By adopting the above technical solution, the position of the pusher plate can be changed by connecting the pusher plate with different through holes. Therefore, the spacing between each pusher plate is adjustable, enabling the device to feed steel coils of different widths, thus making the device more versatile.

[0014] Optionally, the surface of the placement seat for placing the steel coil is provided with a plurality of rollers along the axial direction of the coil shaft.

[0015] By adopting the above technical solution, the roller configuration can transform the sliding friction between the steel coil and the placement seat into rolling friction, resulting in less friction and making the steel coil easier to push.

[0016] Optionally, the placement seats are arranged in a rectangular array, and multiple support plates are provided on the bearing plate along the axial direction of the drum shaft. The length direction of the support plates is perpendicular to the axial direction of the drum shaft. The placement seats are evenly distributed on the support plates, and the support plates are slidably disposed on the bearing plate along their own length direction. A bearing wheel is provided on the side of the support plate away from the placement seats.

[0017] By adopting the above technical solution, after the support plate is slid out, it is easy for the forklift to move to one side of the support plate, thereby moving the steel coil on the forklift onto the support plate. Therefore, the setting of the support plate facilitates the movement of the steel coil from the storage area to the bearing plate.

[0018] Optionally, the support plate is provided with a fixing component, which includes a connecting plate on the support plate, a fixing screw on the connecting plate, and a fixing nut on the fixing screw. There are multiple fixing screws, and their number is the same as the number of support plates. The fixing nut is threaded to the fixing screw. The support plate is provided with a support block, and the support block has a through hole for the fixing screw to pass through. The fixing nut is located on the side of the support block away from the connecting plate.

[0019] By adopting the above technical solution, the sliding support plate allows the corresponding fixing screw to pass through the through hole on the support block. Then, by tightening the fixing nut, the support plate can be fixedly connected to the bearing plate. The fixing process is simple. After fixing the support plate, it can prevent the support plate from sliding during the movement of the steel coil, which helps to improve the stability of the steel coil movement process.

[0020] Optionally, the support plate is provided with an electric winch, which is used to drive the support plate containing the steel coil to slide along its own length.

[0021] By adopting the above technical solution, after the electric winch's cable hooks the support plate, the electric winch can move the support plate containing the steel coil when it retracts the cable, thus smoothly completing the resetting process of the support plate. Since the electric winch's cable can be wound up together, it occupies less space and is easy to install.

[0022] Optionally, a support block is slidably disposed on the bearing plate along the axial direction of the drum shaft, the electric winch is disposed on the support block, and a locking bolt for threaded connection with the bearing plate is disposed on the support block.

[0023] By adopting the above technical solution, the sliding of the support block can drive the electric winch to slide, so the position of the electric winch is easy to adjust, allowing the electric winch to move to the extension line of the length direction of each support plate to apply tension to the support plate, so that the direction of the force applied by the electric winch and the sliding direction of the support plate are on the same straight line, making it easier to pull the support plate to move.

[0024] Optionally, the placement seat includes two symmetrically arranged limiting blocks. The limiting blocks are slidably disposed on the support plate along the length direction of the support plate. An adjustment component is provided between the limiting blocks and the support plate. The adjustment component includes a connecting rod rotatably disposed on the support plate and a double-ended screw coaxially sleeved on the outside of the connecting rod. The connecting rod is disposed along the length direction of the support plate. Multiple double-ended screws are provided. The number of double-ended screws is the same as the number of placement seats on the support plate. The thread directions at both ends of the double-ended screws are opposite. The two limiting blocks are respectively threaded to both ends of the same double-ended screw.

[0025] By adopting the above technical solution, rotating the connecting rod can drive the double-headed screw to rotate, causing the two symmetrically arranged limiting blocks to slide in a direction away from each other, thereby adjusting the distance between the two limiting blocks. This allows the limiting blocks to limit steel coils of different diameters, thus improving the applicability of the device.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A steel coil is placed on the support plate. After the steel coil on the feeding trolley is moved to the drum shaft, the steel coil placed on the support plate can be pushed onto the feeding trolley with the cooperation of the pushing component and the first telescopic component, thus completing the automatic feeding process. Therefore, for a long period of time, the operator does not need to intermittently move the steel coil and can perform other work, which helps to improve work efficiency.

[0028] 2. The support plate is slidably mounted on the support plate, allowing it to slide to one side of the support plate. This facilitates the movement of the forklift to one side of the support plate, and then the steel coils on the forklift are transported onto the support plate. This helps to smoothly move the steel coils from the storage area to the support plate.

[0029] 3. The spacing between the push plates is adjustable, making the device suitable for steel coils of different widths; the spacing between the two limit blocks is adjustable, making the device suitable for steel coils of different diameters, thus the device has a wider range of applications.

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] This application discloses a feeding device for a leveling machine, and its application to an uncoiler is described using an example. (Refer to...) Figure 1 The uncoiler includes an uncoiler body 1 and a drum shaft 2 rotatably disposed at one end of the uncoiler body 1. The drum shaft 2 is horizontally disposed. After the steel coil 15 is loaded onto the drum shaft 2, the tensioning component on the drum shaft 2 is activated, which can tighten the inner hole of the steel coil 15, thereby providing stable support for the steel coil 15. Then, the uncoiler body 1 drives the steel coil 15 to rotate through the drum shaft 2, which can unfold the steel material wound on the steel coil 15, so that the unfolded steel material enters the leveling machine for leveling.

[0040] Reference Figure 1 and Figure 2 The feeding device for the uncoiler is located at the end of the winding drum 2 furthest from the main body 1 of the uncoiler. The feeding device includes a feeding trolley 3, a base plate 4, a support plate 5, a placement seat 7, a first telescopic component 6, and a pushing assembly 8. The feeding trolley 3 includes a guide rail 31, a moving block 32, a linear motor 33, a lifting cylinder 34, a support platform 35, and a triangular block 36. The guide rail 31 is located along the length of the winding drum 2 on the side of the uncoiler main body 1 closest to the winding drum 2. The moving block 32 is slidably mounted on the top surface of the guide rail 31 along its length. The linear motor 33 is located along the length of the guide rail 31, and its output end is fixedly connected to the moving block 32. The lifting cylinder 34 is fixedly mounted on the top surface of the moving block 32, with its piston rod pointing vertically upwards. The support platform 35 is fixedly mounted on the end of the piston rod of the lifting cylinder 34 and is horizontally positioned. Two triangular blocks 36 are provided and symmetrically arranged. The triangular blocks 36 are detachably fixed to the top surface of the support platform 35 by bolts. The top surfaces of the two triangular blocks 36 together form a V-shaped structure, which is used to limit the movement of the steel coil 15. After the steel coil 15 is placed between the two triangular blocks 36, the axis of the steel coil 15 is parallel to the axis of the drum shaft 2, and the two axes are located in a vertical plane.

[0041] Therefore, after the steel coil 15 is moved onto the triangular block 36 by the forklift, the piston rod of the lifting cylinder 34 extends, causing the support platform 35 to move upward. The support platform 35 drives the steel coil 15 to move upward until the axis of the steel coil 15 and the axis of the drum shaft 2 are coaxial. Then, the linear motor 33 drives the steel coil 15 to move towards the side closer to the drum shaft 2 through the moving block 32 and the support platform 35 until the steel coil 15 is fitted onto the outside of the drum shaft 2. Then, the piston rod of the lifting cylinder 34 retracts, causing the support platform 35 to move downward. The output end of the linear motor 33 then moves in the opposite direction, causing the moving block 32 to move to the side away from the drum shaft 2, thus completing the loading process of the steel coil 15.

[0042] Reference Figure 2 and Figure 3The base plate 4 is located at the end of the guide rail 31 away from the drum shaft 2, and the base plate 4 is horizontally positioned. The support plate 5 is located on the top surface of the base plate 4, and the support plate 5 is also horizontally positioned. The length direction of the support plate 5 is perpendicular to the axis of the drum shaft 2, and the width direction of the support plate 5 is parallel to the axis of the drum shaft 2. The support plate 5 is provided with a placement seat 7 for placing the steel coil 15. Multiple placement seats 7 are arranged in a rectangular array, with the rectangular array direction being both parallel to and perpendicular to the axis of the drum shaft 2. In this embodiment, the placement seats 7 are arranged in three rows and three columns, for a total of nine seats. The placement seat 7 includes a base block 71 and a limiting block 72. The base block 71 is fixedly connected to the bearing plate 5 by bolts. There are two limiting blocks 72, which are symmetrically arranged on the top surface of the base block 71. The length direction of the limiting block 72 is parallel to the axis of the drum shaft 2. The top surfaces of the two limiting blocks 72 are provided with inclined surfaces 721 on the side that are close to each other. The two inclined surfaces 721 together form a V-shaped limiting structure to limit the steel coil 15 placed between the two limiting blocks 72. Under normal conditions, the piston rod of the lifting cylinder 34 is in the retracted state, and the triangular block 36 on the support platform 35 is in a lower position. At this time, the limiting block 72 and the inclined surface 721 on the triangular block 36 are at the same height, the slope of the limiting block 72 and the inclined surface 721 on the triangular block 36 are the same, and the distance between the two limiting blocks 72 and the distance between the two triangular blocks 36 are the same. Therefore, the axes of the steel coil 15 placed on the limiting block 72 and the steel coil 15 placed on the triangular block 36 are in the same horizontal plane. By simply moving the support plate 5 in the horizontal direction, the steel coil 15 placed on the limiting block 72 and the steel coil 15 placed on the triangular block 36 can be made to be in a coaxial state.

[0043] The first telescopic component 6 is a hydraulic cylinder. The first telescopic component 6 is fixedly connected to the base plate 4 by bolts. The telescopic direction of the first telescopic component 6 is set horizontally and perpendicular to the axis of the drum shaft 2. The piston rod of the first telescopic component 6 faces the side closer to the drum shaft 2. The piston rod of the first telescopic component 6 is fixedly connected to one end of the bearing plate 5. Therefore, the first telescopic component 6 can drive the bearing plate 5 to move.

[0044] Reference Figure 3 and Figure 4The pushing assembly 8 is located on one side of the support plate 5 and includes a second telescopic member 81, a third telescopic member 82, and a push plate 83. Both the second telescopic member 81 and the third telescopic member 82 are hydraulic cylinders. The second telescopic member 81 is bolted to the base plate 4 and is located on the side of the support plate 5 away from the drum shaft 2, with its piston rod pointing vertically upwards. The third telescopic member 82 is bolted to the end of the piston rod of the second telescopic member 81. The extension / retraction direction of the third telescopic member 82 is parallel to the axis of the drum shaft 2, and its piston rod faces towards the side closest to the drum shaft 2. The third telescopic member 82 is located above the support plate 5. The push plate 83 is fixedly located below the end of the piston rod of the third telescopic member 82. The surface of the push plate 83 is perpendicular to the extension / retraction direction of the third telescopic member 82. Three push plates 83 are provided and evenly spaced. Therefore, the third telescopic member 82 can drive the push plate 83 to move, thereby causing the push plate 83 to push the steel coil 15 placed on the placement seat 7 to move along its own axis, so that the steel coil 15 on the bearing plate 5 can be moved onto the triangular block 36 of the loading trolley 3. In order to reduce the resistance encountered by the steel coil 15 during movement, multiple rollers 722 are evenly spaced along their own length on the inclined surface 721 of the limiting block 72, thereby making it easier for the steel coil 15 to move.

[0045] To further improve the applicability of the device, enabling it to feed steel coils 15 of different widths, refer to... Figure 4 The push plate 83 is detachably connected to the third telescopic member 82. The piston rod end of the third telescopic member 82 is bolted to a push rod 821. The push rod 821 is positioned along the telescopic direction of the third telescopic member 82, and has multiple through holes 8211 evenly spaced along its length. The push plate 83 is mounted on the push rod 821, and a connecting bolt 8212 passes between the through holes 8211 on the push rod 821 and the push plate 83. A connecting nut 8213 is threaded onto the end of the connecting bolt 8212. The push plate 83 can be detachably connected to the push rod 821 through the cooperation of the connecting bolt 8212 and the connecting nut 8213. Therefore, the spacing between adjacent push plates 83 is adjustable. Even if the width of the steel coil 15 changes, the push plate 83 can still smoothly push the steel coil 15 to move, thereby moving the steel coil 15 on the bearing plate 5 onto the loading trolley 3.

[0046] Under normal conditions, a row of steel coils 15 placed on the support plate 5 is coaxial with the steel coils 15 placed on the loading trolley 3. When the steel coils 15 on the drum shaft 2 are exhausted, the loading trolley 3 moves the steel coils 15 onto the drum shaft 2 and then moves back to its original position, leaving the triangular block 36 of the loading trolley 3 empty. At this time, the piston rod of the second telescopic member 81 retracts, causing the third telescopic member 82 to move downward, thereby driving the push plate 83 to move downward; then the piston rod of the third telescopic member 82 extends, driving the push plate 83 to move, and the push plate 83 pushes the steel coils 15 to move, on the one hand pushing the steel coils 15 on the support plate 5 closest to the loading trolley 3 onto the loading trolley 3, and on the other hand moving the last two steel coils 15 forward a certain distance, so that the steel coils 15 on the support plate 5 can be pushed onto the loading trolley 3 again in the next pushing process. Next, the piston rod of the second telescopic member 81 extends, driving the third telescopic member 82 and the push plate 83 to move upward. Then, the piston rod of the third telescopic member 82 retracts to reset, facilitating the next movement of the steel coils 15 on the support plate 5. After all three steel coils 15 that are coaxial with the steel coils 15 placed on the loading trolley 3 have been moved out of the support plate 5, the piston rod of the first telescopic member 6 extends, pushing the support plate 5 to move a certain distance, so that the second row of steel coils 15 on the support plate 5 moves to a position coaxial with the steel coils 15 placed on the loading trolley 3, thereby facilitating the movement of the steel coils 15 on the support plate 5 onto the loading trolley 3.

[0047] In order to enable the steel coil 15 to move more stably, under normal conditions, the distance between the triangular block 36 and the limiting block 72 closest to the drum shaft 2 is equal to the distance between two adjacent limiting blocks 72 along the axial direction of the drum shaft 2. Therefore, each steel coil 15 can move to the required position by moving the same distance.

[0048] After the steel coils 15 placed on the support plate 5 are used up, they need to be moved from the storage area to the support plate 5 using a forklift. To ensure that operators can promptly move the steel coils 15 and reduce downtime of the leveling machine, refer to... Figure 3 An alarm 14 is installed on the support plate 5. When all the steel coils 15 on the support plate 5 are removed, the alarm 14 will sound an alarm to remind the operator to replenish the steel coils 15 on the support plate 5.

[0049] When a forklift moves the steel coil 15, the forklift's support rod at the front must first be inserted into the center hole of the steel coil 15. Then, the forklift drives the support rod upwards, thus moving the steel coil 15 upwards. Next, the forklift moves the steel coil 15 directly above the desired position, and then the forklift drives the support rod downwards to lower the steel coil 15. Because the steel coils 15 placed on the support plate 5 are arranged in an array, it is difficult to move the support rod on the forklift to a position close to the drum shaft 2, making it difficult for the forklift to move the steel coil 15 to the side of the support plate 5 closest to the drum shaft 2. To facilitate moving the steel coil 15 from the storage area to the support plate 5, refer to... Figure 5 and Figure 6 Support plates 9 are provided on the support plate 5. There are three support plates 9, all of which are elongated structures. Placement seats 7 are provided on the top surface of the support plate 9, and three placement seats 7 are evenly spaced along the length of each support plate 9. The three support plates 9 are evenly spaced along the width of the support plate 5, and the length of each support plate 9 is parallel to the length of the support plate 5. The surface of the support plate 9 is horizontal. A slider 91 is welded to the bottom wall of the support plate 9 along its length. The slider 91 has a T-shaped cross-section. A groove 51 with the same shape as the slider 91 is opened on the top surface of the support plate 5. The groove 51 is provided along the length of the support plate 5. The slider 91 is slidably engaged in the groove 51, so that the support plate 9 and the support plate 5 are slidably connected.

[0050] Therefore, when it is necessary to move the steel coil 15 onto the support plate 5, first slide the support plate 9 closest to the drum shaft 2 outwards. Then, the forklift can place the steel coil 15 onto the three placement seats 7 on this support plate 9 in sequence. Next, slide the support plate 9 containing the steel coil 15 towards the side closest to the support plate 5 until it slides to the initial position. Since the steel coil 15 is relatively heavy, multiple support wheels 92 are evenly spaced along their own length on both sides of the bottom of the support plate 9. The support plate 5 has clearance grooves 52 for the support wheels 92 to slide. The depth of the clearance grooves 52 is the same as the thickness of the support plate 5, so that the bottom of the support wheel 92 abuts against the bottom plate 4, and the bottom plate 4 supports the support wheel 92.

[0051] When the support plate 9, on which the steel coil 15 is placed, is slid towards the side closer to the bearing plate 5, the weight of the steel coil 15 makes it difficult to move. To facilitate the movement of the support plate 9, an electric winch 11 is provided on the bearing plate 5 at one end of the support plate 9. A connecting rod 93 is welded to the end of the support plate 9 near the electric winch 11. The connecting rod 93 is parallel to the width direction of the support plate 9. After the winch hook on the electric winch 11 hooks the connecting rod 93, the winch 11 can drive the support plate 9 to move towards the side closer to the bearing plate 5 during the process of retracting the winch cable, which is more convenient and less strenuous.

[0052] Reference Figure 5 and Figure 7The support plate 9 has three sections. To allow the electric winch 11 to better apply force to the support plate 9 and thus move it, a support block 12 is slidably mounted on the bearing plate 5 along its width. A locking block 121 is welded to the bottom of the support block 12. A locking groove 53 is provided at one end of the bearing plate 5 near the electric winch 11. The shape of the locking groove 53 is the same as that of the locking block 121, and the locking groove 53 is set along the width direction of the bearing plate 5. The locking block 121 is slidably engaged in the locking groove 53, so that the support block 12 is slidably mounted on the bearing plate 5. The electric winch 11 is fixedly connected to the top surface of the support block 12 by bolts, so the support block 12 can drive the electric winch 11 to slide. The support block 12 has a vertical connecting hole 122, through which a locking bolt 123 passes. The bearing plate 5 has three threaded holes 54 on one side of the slot 53, each evenly spaced along the width of the bearing plate 5, and each threaded hole 54 is located on the extension line of the length of the bearing plate 9. Therefore, by sliding the support block 12 and screwing the locking bolt 123 into the corresponding threaded hole 54, the support block 12 can be fixedly connected to the bearing plate 5, allowing the electric winch 11 to be stably positioned on the extension line of the length of the bearing plate 9. The direction of the force applied by the electric winch 11 to the bearing plate 9 is the same as the direction of the sliding of the bearing plate 9, making it easier to drive the bearing plate 9 to slide.

[0053] Since the support plate 9 is slidable, a fixing component 10 is provided on the bearing plate 5 to improve its stability. The fixing component 10 includes a connecting plate 101, fixing screws 102, and fixing nuts 103. The connecting plate 101 is a long strip structure, welded to the top surface of one end of the bearing plate 5, and is arranged along the width direction of the bearing plate 5. Three fixing screws 102 are provided and are evenly spaced and welded to the connecting plate 101 along its length direction. The fixing screws 102 are located on the side of the connecting plate 101 closest to the support plate 9, are parallel to the length direction of the support plate 9, and each fixing screw 102 is located on the extension line of the length direction of the support plate 9. A support block 94 is welded to one end of the support plate 9 near the connecting plate 101. The support block 94 has a through hole 941 coaxially arranged with the corresponding fixing screw 102. The end of the fixing screw 102 away from the connecting plate 101 passes through the through hole 941, and the fixing nut 103 is threadedly connected to the end of the fixing screw 102 that passes through. The side of the support block 94 away from the connecting plate 101 abuts against the fixing nut 103, thereby fixing the loaded support plate 9 to the bearing plate 5. This makes it difficult for the support plate 9 to slip during the movement of the steel coil 15, which helps to ensure the stability of the movement of the steel coil 15.

[0054] To further enhance the applicability of the device and enable it to feed steel coils 15 of different diameters, the spacing between the two limiting blocks 72 on the same base block 71 is adjustable. The base block 71 is fixedly connected to the top surface of the support plate 9 by bolts. A connecting block 723 is provided at the bottom of the limiting block 72. A guide groove 712 is formed on the top surface of the base block 71 along the length direction of the support plate 9. The connecting block 723 is slidably engaged in the guide groove 712, so that the limiting block 72 is slidably connected to the base block 71. An adjustment assembly 13 is provided between the limiting block 72 and the base block 71. The adjustment assembly 13 is provided in three sets, each corresponding to a support plate 9, and is used to adjust the spacing between two adjacent limiting blocks 72 on that support plate 9.

[0055] The adjusting assembly 13 includes a connecting rod 131 and a double-ended screw 132. The connecting rod 131 is arranged along the length of the support plate 9, and a circular hole 711 is provided on the bottom block 71. The connecting rod 131 passes through the circular hole 711 and is rotatably connected to the support plate 9 by a bearing. A rotating block 1311 is welded to one end of the connecting rod 131 to facilitate the rotation of the connecting rod 131. Three double-ended screws 132 are provided and evenly spaced along the length of the connecting rod 131. Each double-ended screw 132 corresponds to a placement seat 7. A through hole 8211 is coaxially opened inside the double-ended screw 132. The diameter of the through hole 8211 is the same as the diameter of the connecting rod 131. The double-ended screw 132 is coaxially sleeved on the outer wall of the connecting rod 131. The double-ended screw 132 and the connecting rod 131 are welded and fixed. The threads at both ends of the outer wall of the double-ended screw 132 are in opposite directions. Two connecting blocks 723 on each base block 71 are threadedly connected to the two ends of a double-ended screw 132. Therefore, under the limiting action of the guide groove 712 on the connecting blocks 723, rotating the connecting rod 131 can drive the double-ended screw 132 to rotate, so that the two connecting blocks 723 on the same base block 71 move in opposite directions, thereby adjusting the distance between the two limiting blocks 72, so that the limiting blocks 72 can limit steel coils 15 of different sizes. In addition, the top of the connecting block 723 and the bottom of the limiting block 72 are detachably connected by bolts, so the limiting block 72 with different inclination degrees of the inclined surface 721 can be replaced as needed to further ensure the limiting effect on the steel coil 15.

[0056] After adjusting the distance between the two limiting blocks 72 and replacing the limiting blocks 72, the triangular block 36 on the top of the support platform 35 needs to be removed and replaced with a new triangular block 36, ensuring that the inclined surface 721 on the triangular block 36 is the same as the inclined surface 721 on the limiting block 72. Then, the distance between the two triangular blocks 36 is adjusted to be equal to the distance between the two limiting blocks 72. Therefore, after adjusting the limiting blocks 72, the steel coil 15 placed on the limiting blocks 72 can still be in a coaxial state with the steel coil 15 placed on the triangular block 36, which facilitates the pushing assembly 8 to move the steel coil 15 onto the triangular block 36.

[0057] The implementation principle of the feeding device for a slitting machine according to an embodiment of this application is as follows: When the steel coil 15 on the drum shaft 2 is exhausted, the piston rod of the lifting cylinder 34 extends, causing the support platform 35 to move upward, thereby driving the steel coil 15 placed on the support platform 35 to move upward until the steel coil 15 is coaxial with the drum shaft 2; then the linear motor 33 drives the steel coil 15 to move towards the side closer to the drum shaft 2 through the moving block 32 until the steel coil 15 is sleeved on the outside of the drum shaft 2; then the support platform 35 moves downward again, and the moving block 32 moves away from the drum shaft 2 again, returning to the initial position, completing the feeding process of the slitting machine, and then the feeding trolley 3 begins to be fed.

[0058] First, the piston rod of the second telescopic member 81 retracts, causing the third telescopic member 82 and the push plate 83 to move downwards. Then, the piston rod of the third telescopic member 82 extends, pushing a row of steel coils 15 placed on the support plate 5 towards the side closest to the drum shaft 2 via a baffle. This pushes the steel coils 15 closest to the drum shaft 2 onto the triangular block 36 at the top of the support platform 35, while simultaneously pushing the steel coils 15 furthest from the drum shaft 2 forward a short distance to facilitate the next loading process. Next, the piston rod of the second telescopic member 81 extends, causing the third telescopic member 82 and the push plate 83 to move upwards. Finally, the piston rod of the third telescopic member 82 retracts, causing the push plate 83 to reset. When the steel coil 15 on the drum shaft 2 is exhausted again, the loading trolley 3 transports the steel coil 15 back onto the drum shaft 2 and then resets. Under the action of the second telescopic member 81 and the third telescopic member 82, the steel coil 15 closest to the drum shaft 2 is pushed onto the loading trolley 3, while the steel coil 15 on the bearing plate 5 away from the drum shaft 2 is pushed forward a distance to facilitate the next loading.

[0059] After all the steel coils 15 on the support plate 5 and the steel coils 15 placed on the loading trolley 3 that were coaxial have been removed, the piston rod of the first telescopic member 6 extends, causing the support plate 5 to move a certain distance. This moves the second row of steel coils 15 on the support plate 5 to a coaxial position with the steel coils 15 placed on the loading trolley 3, facilitating the movement of the steel coils 15 onto the loading trolley 3 with the cooperation of the second telescopic member 81 and the third telescopic member 82. Therefore, by simply moving the steel coils 15 onto the support plate 5 using a forklift before the uncoiler starts operating, the uncoiler can automatically feed for a longer period of time. Compared to traditional intermittent feeding, the process is simpler, and operators do not need to feed the steel coils periodically, allowing them more time for other tasks and thus improving work efficiency.

[0060] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
