Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheet processing, and more specifically, to an automatic feeding device for a galvanized sheet take-up reel. Background Art

[0002] A galvanized sheet is a thin steel sheet with a layer of zinc plated on its surface. This zinc-coated steel sheet has good anti-corrosion performance and is widely used in multiple industries. Galvanized sheets are usually stored in rolls. To facilitate the feeding of galvanized sheets, an automatic feeding device for a galvanized sheet take-up reel is thus established to automatically feed the galvanized sheet coils, so as to facilitate the subsequent processing of galvanized sheets by equipment.

[0003] After retrieval, a patent with the Chinese patent application number 202122961802.7 discloses a steel coil uncoiling and feeding device, which includes a base. A fixing component is rotatably connected to the surface of the base. The fixing component includes a rotating disk, the circumferential side surface of the rotating disk is rotatably connected to the base, a first threaded lead screw is rotatably connected to the surface of the rotating disk, two moving seats are threadedly connected to the circumferential side surface of the first threaded lead screw, a group of support rods are hinged to the circumferential side surfaces of the two moving seats, a group of support plates are slidably connected to the surface of the rotating disk, one surface of each of the group of support plates is hinged to the corresponding support rod, and two mounting plates are fixedly connected to one surface of the base. A second threaded lead screw is rotatably connected between the two mounting plates. The purpose of the utility model is to provide a steel coil uncoiling and feeding device to solve the problems that in the process of using the existing steel coil uncoiling machine, the uncoiling speed often becomes too fast, thus affecting the subsequent processing operations, and its poor applicability, so that it is difficult to fix steel coil rollers with various different diameters;

[0004] The above patent still has the following deficiencies: (1) It has the defect of being inconvenient for installing the take-up roller. Since the weight of the galvanized sheet coil is large, it is extremely inconvenient for workers to install the galvanized sheet coil, requiring the cooperation of suspension tools, consuming a lot of manpower and material resources, and being prone to safety hazards due to improper operation;

[0005] (2) It is not convenient for the defect that the galvanized sheet coil is prone to looseness. Since the galvanized sheet coil has a certain elasticity, during the feeding process of the device, the galvanized sheet is prone to spread outwards, resulting in the need to pause the production line to re-organize the coil, increasing the downtime of the equipment, and thus reducing the overall production efficiency.

[0006] Therefore, there is an urgent need for an automatic feeding device for a galvanized sheet take-up reel to solve the above problems. Summary of the Utility Model

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0031] As Figures 1-4 shown, an automatic loading device for a galvanized sheet winding drum proposed in this embodiment includes a bottom plate 1, and further includes:

[0032] A support frame 4, fixed on both sides of the top end of the bottom plate 1;

[0034] A support seat 3, fixed on one side of the top end of the bottom plate 1, and a driving motor 6 is installed on the top end of the support seat 3, and a first transmission wheel 7 is connected to the rotating end of the driving motor 6;

[0035] A roll pressing structure 5, arranged on the top end of the support seat 3, for pressing the coil;

[0036] A winding roller 9, arranged on one side of the top end of the support frame 4, and roller bearings 11 are sleeved on the outer sides of both sides of the winding roller 9. A baffle 8 is fixed on one side of the winding roller 9, and a second transmission wheel 12 connected to the winding roller 9 is arranged on one side of the baffle 8. A rotating block 16 is inserted into the inside of the other side of the winding roller 9;

[0037] A bidirectional lead screw 13, rotatably connected inside the winding roller 9, and a moving ring 15 is threadedly connected to the outer side of the bidirectional lead screw 13. A pushing arm 14 is rotatably connected to the outer side of the moving ring 15, and one end of the pushing arm 14 is rotatably connected to a pushing plate 10.

[0038] As Figure 1 and Figure 2 shown, as a preferred embodiment, on the basis of the above method, further, the transmission assembly includes rocker arms 204 installed on both sides of the rotating rod 201, reinforcing plates 202 installed on one side of the rocker arms 204, and a first hydraulic push rod 205 rotatably connected to one side of the rocker arms 204 and connected to the support frame 4. A rotating structure is formed between the first hydraulic push rod 205 and the support frame 4. A rotating structure is formed between the fixed seat 206 and the moving seat 207 through the roller bearing 11 and the winding roller 9. There are two groups of rocker arms 204, and the rocker arms 204 are symmetrically distributed on the vertical center line of the bottom plate 1. Use a cart to move the coil to one side of the moving seat 207 and align the moving seat 207 with the roller bearing 11. Start the first hydraulic push rod 205 to contract, pull the rocker arm 204 to flip around the rotating rod 201, so that the moving seat 207 moves to the outside of the roller bearing 11. Immediately, the first hydraulic push rod 205 continues to contract, and the rocker arm 204 pushes the coil upward through the moving seat 207 to move it to the top of the support frame 4. At the same time, the moving seat 207 fits and locks with the fixed seat 206 to fix the position of the coil. The left and right two groups of rocker arms 204 are connected and fixed by the reinforcing plate 202 to make the lifting of the coil stable.

[0039] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the rolling structure 5 includes a second hydraulic push rod 506 rotatably connected to the top of the support seat 3, a crank 505 rotatably connected to the top of the second hydraulic push rod 506, support plates 503 fixed on both sides of the top of the support frame 4, a rotating shaft 504 rotatably connected inside the support plates 503 and connected to the crank 505, a connecting arm 502 fixed on the outside of the rotating shaft 504, and a pressing roller 501 installed on one side of the connecting arm 502. A welded integrated structure is formed between the crank 505 and the rotating shaft 504, and a rotating connection is formed between the support plate 503 and the rotating shaft 504. By starting the second hydraulic push rod 506 to extend, the second hydraulic push rod 506 pushes the crank 505 to move. At the same time, the crank 505 drives the rotating shaft 504 to rotate inside the support plate 503, and the support plate 503 drives the connecting arm 502 to flip. Place the pressing roller 501 on the outside of the coil. As the telescopic length of the second hydraulic push rod 506 increases, the pressure of the pressing roller 501 on the coil increases, thereby pressing the coil to prevent the coil from spreading easily. By rotating the pressing roller 501 on the outside of the connecting arm 502, the pressing roller 501 can rotate along with the coil.

[0040] Specifically, when the galvanized sheet winding drum automatic feeding device is in use: by inserting the winding roller 9 into the interior of the coil, using a wrench or other tools to rotate the rotary block 16, the rotary block 16 drives the bidirectional screw rod 13 to rotate, and then the bidirectional screw rod 13 pushes the movable ring 15 to move inside the winding roller 9 through the thread, and at the same time, the left and right groups of movable rings 15 move downward, so that the push arm 14 pushes the push plate 10 to expand outward, and the winding roller 9 is fixed inside the coil by the four groups of push plates 10 against the cavity inside the coil. Then, the trolley is used to move the coil to one side of the coil changing structure 2, and the coil changing structure 2 is used to drive the coil to move, and the coil is changed, and the position of the fixed coil is locked, and the roller pressing structure 5 is used to press the coil so that the coil is not easy to spread during the rotation process, and the second transmission wheel 12 is connected to the first transmission wheel 7 by a transmission belt, and the drive motor 6 is started to drive the winding roller 9 to rotate through the first transmission wheel 7 and the second transmission wheel 12, so that the coil is fed;

[0041] Use a cart to move the coil to one side of the moving seat 207, and align the moving seat 207 with the roller bearing 11, start the first hydraulic push rod 205 to retract, pull the rocker arm 204 to flip around the rotating rod 201, so that the moving seat 207 moves to the outside of the roller bearing 11, and then the first hydraulic push rod 205 continues to retract, and the rocker arm 204 pushes the coil upward through the moving seat 207 to move it to the top of the support frame 4. At the same time, the moving seat 207 and the fixed seat 206 are locked and fixed in the position of the coil, and the left and right sets of rocker arms 204 are connected and fixed by the reinforcing plate 202 to ensure the stability of the coil lifting;

[0042] By starting the second hydraulic push rod 506 to extend, the second hydraulic push rod 506 pushes the crank 505 to move, and at the same time the crank 505 drives the rotating shaft 504 to rotate inside the support plate 503, and the support plate 503 drives the connecting arm 502 to flip, so that the pressure roller 501 is placed on the outside of the coil. As the length of the second hydraulic push rod 506 increases, the pressure of the pressure roller 501 on the coil increases, thereby pressing the coil, making it difficult for the coil to spread out, and the pressure roller 501 rotates on the outside of the connecting arm 502, so that the pressure roller 501 can rotate along with the coil.

[0043] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
