[0002] Steel coils, also known as coiled steel, are formed into coils by hot pressing and cold pressing of steel. For the convenience of storage, transportation and various processing (such as processing into steel plates, steel strips, etc.), during the production process of spare parts, steel coils are used as raw materials and placed at the end of the production line. The feeding mechanism drives the steel coil to rotate to realize the feeding of the steel coil.

[0003] Chinese Patent Publication No. CN220992380U discloses a steel coil feeding mechanism, including a base. A support vertical plate is fixedly connected to the upper end of the base. The middle part of the front end of the support vertical plate is rotatably connected with a mounting shaft.

The support plates are connected to the support vertical plate through a tensioning mechanism. A detection and alarm mechanism acting on the steel coil is arranged on the rear side wall of the support vertical plate.

[0004] However, the inventor believes that the above device has certain defects. The above device feeds the steel coil by sleeving it on the mounting shaft, with poor adaptability and difficulty in installing and fixing steel coil rollers with different inner diameters. Therefore, the utility model provides a feeding mechanism for steel coils. Content of the Utility Model

[0007] (2) Technical Solutions

[0008] The utility model is realized through the following technical solutions: a feeding mechanism for steel coils, including a fixed frame. A feeding cylinder is rotatably connected to the fixed frame. A sliding rod is slidably connected to the feeding cylinder. One end of the sliding rod is fixedly connected with a movable plate. Two movable blocks are arranged inside the feeding cylinder. Each movable block is provided with a pressing groove. The other end of the sliding rod is fixedly connected with a connecting frame. A sliding rod is fixedly connected inside the connecting frame. The sliding rod is arranged inside the pressing groove. An adjusting mechanism for adjusting the two movable blocks to approach or separate from each other is arranged inside the feeding cylinder. A fixed seat is fixedly connected to the fixed frame. A supporting mechanism for supporting the bottom of the steel coil is arranged at one end of the fixed seat.

[0009] Preferably, the adjusting mechanism includes a bidirectional screw rotatably disposed inside the feeding cylinder. Both of the movable blocks are threadedly connected to the bidirectional screw. A second motor for driving the bidirectional screw to rotate is fixedly connected inside the feeding cylinder. By starting the second motor, the bidirectional screw is driven to rotate inside the feeding cylinder, causing the two movable blocks to move closer to or away from each other.

[0010] Preferably, the supporting mechanism includes a support plate. One end of the fixed seat is slidably connected with a sliding block, and the support plate is fixedly connected to one end of the sliding block. The bottom of the steel coil is supported by the provided support plate.

[0011] Preferably, two rollers are rotatably connected to the inner wall of the support plate. The inner bottom wall of the fixed seat and the bottom of the sliding block are connected by a spring. The bottom of the steel coil is slidably supported by the rollers, reducing the friction between the bottom of the steel coil and the support plate.

[0012] Preferably, a driving rod is rotatably connected inside the fixed seat. A winding drum is fixedly connected to the driving rod. A pulling rope is wound around the winding drum. The other end of the pulling rope is fixedly connected to the bottom of the sliding block. A third motor for driving the driving rod to rotate is fixedly connected to the fixed frame. By starting the third motor, the driving rod is driven to rotate, causing the winding drum to wind up the pulling rope.

[0013] Preferably, a through groove is formed at one end of the fixed seat. A connecting plate is fixedly connected to one end of the sliding block. The connecting plate slides inside the through groove. A pressing sensor corresponding to the connecting plate is fixedly connected to one end of the fixed seat. When the sliding block rises due to elastic force, the connecting plate is driven to slide upward inside the through groove, and the pressing sensor is squeezed by the connecting plate to transmit a signal.

[0014] Preferably, a first motor for driving the feeding cylinder to rotate is fixedly connected to the fixed frame. Both the first motor and the pressing sensor are electrically connected to an external control device. By starting the first motor, the feeding cylinder is driven to rotate, causing the steel coil fixed on the feeding cylinder to be fed.

[0015] The present utility model provides a feeding mechanism for a steel coil, and the beneficial effects thereof are as follows:

[0016] 1. The device controls the two movable blocks to move closer to or away from each other inside the feeding cylinder through the adjusting mechanism. Under the action of the extrusion groove, the sliding rod, the connecting frame and the sliding rod, the distance between the two movable plates is adjusted to fix steel coils with different inner diameters, and the adaptability is good. The bottom of the steel coil is supported by the supporting mechanism at one end of the fixed seat, sharing the gravity of the steel coil on the feeding cylinder and improving its service life.

[0017] 2. Under the action of the spring force, as the steel coil is fed, the outer diameter of the steel coil gradually decreases, driving the sliding block to slide upward gradually. When the connecting plate slides upward and presses the pressure sensor, the signal that the steel coil is about to run out is transmitted to remind the staff to replace it in time, effectively improving the work efficiency.

Detailed Embodiment

[0025] The embodiment of the present utility model provides a feeding mechanism for a steel coil.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a feeding mechanism for a steel coil, including a fixed frame 1, a feeding cylinder 2 is rotatably connected to the fixed frame 1, a sliding rod 31 is slidably connected to the feeding cylinder 2, one end of the sliding rod 31 is fixedly connected to a movable plate 3, the steel coil is sleeved on the feeding cylinder 2, and by controlling the sliding rod 31 to slide outward, the movable plate 3 is used to tightly press against the inner wall of the steel coil to install and fix the steel coil, and the steel coil is fed by driving the feeding cylinder 2 to rotate.

[0027] Please refer to again Figure 1 , Figure 2 and Figure 3, there are two movable blocks 22 inside the feeding cylinder 2. Each movable block 22 is provided with an extrusion groove 23. The other end of the sliding rod 31 is fixedly connected with a connecting frame 32. Inside the connecting frame 32, a sliding rod 33 is fixedly connected. The sliding rod 33 is arranged inside the extrusion groove 23. The extrusion groove 23 is inclined. By moving the two movable blocks 22 closer to or away from each other, the extrusion groove 23 squeezes the sliding rod 33, and under the connection action of the connecting frame 32, the sliding rod 31 is pushed or pulled to slide.

[0028] Please refer to again Figure 1 , Figure 2 and Figure 3 , inside the feeding cylinder 2, there is an adjusting mechanism for adjusting the two movable blocks 22 to move closer to or away from each other. The adjusting mechanism includes a bidirectional screw 21 rotatably arranged inside the feeding cylinder 2. The two movable blocks 22 are both threadedly connected to the bidirectional screw 21. The bidirectional screw 21 is a screw with two external threads, and the directions of the two external threads are opposite. Inside the feeding cylinder 2, a second motor 24 for driving the bidirectional screw 21 to rotate is fixedly connected. Starting the second motor 24 to drive the bidirectional screw 21 to rotate, when the bidirectional screw 21 rotates, the two movable blocks 22 move closer to or away from each other.

[0029] Please refer to again Figure 1 , Figure 4 and Figure 5 , on the fixed frame 1, a fixed seat 4 is fixedly connected. One end of the fixed seat 4 is provided with a supporting mechanism for supporting the bottom of the steel coil. The supporting mechanism supports the bottom of the steel coil to reduce the influence of the gravity of the steel coil on the feeding cylinder 2. The supporting mechanism includes a supporting plate 6. One end of the fixed seat 4 is slidably connected with a sliding block 5. The supporting plate 6 is fixedly connected to one end of the sliding block 5. Two rollers 61 are rotatably connected to the inner wall of the supporting plate 6. Under the action of the rollers 61, the friction between the supporting plate 6 and the steel coil is reduced, which is convenient for feeding the steel coil. Between the inner bottom wall of the fixed seat 4 and the bottom of the sliding block 5, they are connected by a spring 41. When the sliding block 5 is squeezed and slides downward in a way of compressing the spring 41, when there is no force on the top of the sliding block 5, the supporting plate 6 is driven to slide upward by the rebound of the spring 41.

[0030] Please refer to again Figure 1 , Figure 4 and Figure 5, a driving rod 42 is rotatably connected inside the fixed seat 4. A winding drum is fixedly connected to the driving rod 42. A pulling rope 43 is wound around the winding drum. The other end of the pulling rope 43 is fixedly connected to the bottom of the sliding block 5. A third motor 44 for driving the driving rod 42 to rotate is fixedly connected to the fixed frame 1. By starting the third motor 44, the driving rod 42 is driven to rotate inside the fixed seat 4. The pulling rope 43 is wound by the winding drum on the driving rod 42, so as to pull the whole support plate 6 to descend during the installation of the steel coil. By driving the driving rod 42 to rotate in the reverse direction, the pulling rope 43 is relaxed, and the support plate 6 is driven to rise by the rebound of the spring 41. And during the whole feeding process, the pulling rope 43 is in a relaxed state and does not affect the normal sliding of the sliding block 5.

[0031] Please refer to again Figure 1 , Figure 4 and Figure 5 , a through groove is formed at one end of the fixed seat 4. One end of the sliding block 5 is fixedly connected with a connecting plate 51. The connecting plate 51 slides inside the through groove. A pressing sensor 7 corresponding to the connecting plate 51 is fixedly connected to one end of the fixed seat 4. As the feeding progresses, the outer diameter of the steel coil gradually decreases. The sliding block 5 slides upward under the action of the elastic force of the spring 41. When the connecting plate 51 slides to press the pressing sensor 7, the signal that the steel coil is about to be used up is transmitted to remind the staff to replace it in time. A first motor 11 for driving the feeding cylinder 2 to rotate is fixedly connected to the fixed frame 1. The first motor 11 and the pressing sensor 7 are both electrically connected to the external control device. By starting the first motor 11, the feeding cylinder 2 is driven to rotate for feeding.

[0032] Working principle: Install the device at a suitable position and connect it to the municipal power supply and the control device. By starting the third motor 44, the winding drum on the driving rod 42 winds the pulling rope 43. Under the action of the pulling rope 43, the sliding block 5 is pulled to slide downward. The steel coil is sleeved on the feeding cylinder 2. The driving rod 42 is driven to rotate in the reverse direction to relax the pulling rope 43. Then, by starting the second motor 24, the bidirectional screw rod 21 is driven to rotate inside the feeding cylinder 2, so that the two movable blocks 22 approach or move away from each other. The sliding rod 31 is pushed to extend outward by squeezing the sliding rod 33 through the squeezing groove 23, so that the movable plate 3 abuts against the inner wall of the steel coil to fix the steel coil. By starting the first motor 11, the feeding cylinder 2 is driven to rotate for feeding. As the feeding progresses, the outer diameter of the steel coil gradually decreases. The sliding block 5 slides upward under the action of the elastic force of the spring 41. The feeding amount of the steel coil is understood by observing the rising amplitude of the connecting plate 51. When the connecting plate 51 slides to press the pressing sensor 7, the signal that the steel coil is about to be used up is transmitted to remind the staff to replace it in time.
