[0038] In some technical solutions disclosed in the utility model, a travel switch is also installed in front of the guide column support.

The two transparent covers 8.2 are respectively welded to the axial ends of the roller body 8.1, and the two pressure roller sleeves 8.4 are respectively installed on the inner side of the inner circle of the two transparent covers 8.2 by bolt connection. The pressure roller shaft 8.3 is rotatably connected to the roller body 8.1. Specifically: the pressure roller shaft 8.3 passes through the inner circle of the transparent cover 8.2 and is installed at the axis position of the roller body 8.1 (that is, the pressure roller shaft 8.3 and the roller body 8.1 are coaxial), and the two pressure roller shaft bearings 8.5 are respectively installed in the two pressure roller sleeves 8.4. The outer ring of the pressure roller shaft bearing 8.5 is fixed to the pressure roller sleeve 8.4, and the inner ring of the pressure roller shaft bearing 8.5 is in contact with the bearing platform of the pressure roller shaft 8.3, and the two are transitionally matched.

The roller assembly 8 can provide sufficient pressure to compact and compact the metal sheet and strip waste wrapped around the main shaft 2.6, ensuring that the waste coil does not loosen. This can make the subsequent transportation, material distribution, and unloading processes more convenient and safe, avoiding personal injury. At the same time, the roller assembly 8 can also reduce the vibration amplitude and noise of the entire equipment when the metal sheet and strip waste coils are wound.

In the receiving state, the pushing arc plate 21.1 is located directly below the main shaft 2.6, and the wound waste coil can fall directly on the pushing arc plate 21.1. Then, the pushing hydraulic cylinder 22 drives the pushing arc plate 21.1 to flip and switch to the unloading state. The waste coil on the pushing arc plate 21.1 can roll down directly to complete the unloading.

[0075] In one embodiment, Figures 13 to 16As shown, three notches 2.6.2 are opened at the top of the winding end (i.e., the left shaft end) of the main shaft 2.6, which are used to hang the scrap strip head of the metal plate before winding the scrap. A keyway 2.6.1 is opened on the outer circle of the winding end of the main shaft 2.6. The length of the keyway 2.6.1 is 758mm based on the left end face. After the end (right end) of the keyway 2.6.1 contacts the aforementioned key bar 3, the main shaft 2.6 is inserted into place on the right arch 7. The key bar 3 contacts the end (right end) of the keyway 2.6.1, which can also play a role in axially limiting the main shaft 2.6. Another keyway 2.6.1 is opened on the outer circle of the right end of the main shaft 2.6 for connecting with the output end key of the reducer. The notch 2.6.2 is a conventional design in the scrap winding equipment and will not be described here.

[0076] In one embodiment, Figure 2 As shown, a safety light curtain 23 is also provided.

[0077] In one embodiment, Figure 1 As shown, a travel switch 25 is installed on the guide column 18 in front of the guide column support 19 at the end of the guide column 18 away from the right arch 7 (i.e., the right end of the guide column 18). The travel switch 25 can be communicated with the hydraulic station of the aforementioned forward and backward hydraulic cylinder 15 through the controller. The travel switch 25 can monitor the distance between the sliding seat 17 and it in real time, and can prevent the main shaft 2.6 from damaging the left large plate 10 and its shaft sleeve 4 when moving to the left, and prevent the sliding seat 17 from damaging the guide column support 19 at the right end of the guide column 18 when moving to the right.

[0078] In one embodiment, the base 13 may be connected to anchor bolts pre-buried in the ground to fix the base 13, thereby improving the structural stability and reliability of the entire winding device during operation.

[0079] The specific operation method and action sequence of the improved novel metal plate and strip scrap coiling device 100 are as follows:

[0080] 1. Hooking material - use the hook rod to hook the scrap wire of metal sheet and strip from the pit;

[0081] 2. Hanging - Manually hang the end of the edge wire on the notch 2.6.2 on the left end of the main shaft 2.6;

[0082] 3. Advance the spindle 2.6 - operate the button to make the hydraulic cylinder 15 drive the slide seat 17 to move axially to the left, so that the spindle 2.6 moves to the front position, that is, the spindle 2.6 is inserted into the right arch 7;

[0083] 4. Press the pressure roller device 8 downward - operate the button to make the pressure roller lifting hydraulic cylinder 24 drive the pressure roller device 8 downward;

[0084] 5. Start winding - start the motor 2.1 to drive the reducer 2.2 and the main shaft 2.6 to rotate and wind the waste wire;

[0085] 6. When the diameter or weight of the material roll wound on the main shaft 2.6 reaches the specified value, the motor 2.1 stops, the waste wire is cut, and the material roll head is taped. After the operator reaches a safe area, he operates the knob switch to make the motor 2.1 run at a low speed and tape is wrapped around the material roll. After the tape wrapping is completed, the material roll head is fixed. The motor 2.1 stops and the tape is cut.

[0086] 7. Retract the spindle 2.1 - Press the button to cause the hydraulic cylinder 15 to drive the sliding seat 17 to move axially to the right and withdraw it from the material roll until it retracts to the pressing position. After the material roll is separated from the spindle 2.6, it falls into the pusher arc plate 21.1.

[0087] 8. Pushing - Pressing the push button causes the push cylinder 22 to rotate the push shaft 21.2, which in turn causes the pusher arc plate 21.1 to flip around the axis of the push shaft 21.2, rolling the waste material into the material basket below. After pushing is completed, the push cylinder 22 drives the pusher arc plate 21.1 to flip in the opposite direction, returning it to the material receiving state and waiting for the next round of operation.

[0088] It should be noted that, except for the fifth item, the other operations above require stopping the motor 2.1 before operation. The metal plate and strip scrap coiling device 100 is suitable for coiling scrap generated after slitting of metal plates and strips such as copper, aluminum, and steel.

[0089] The metal plate and strip scrap coiling device 100 disclosed in this solution has the following beneficial effects:

[0090] (1) Aiming at the problem that the scrap edge coiling device of the existing metal plate and strip scrap edge winding device is loose and easily causes casualties to the winding workers and the material distribution workers, this solution arranges a pressure roller device above the main shaft of the rotating device and arranges a pressure roller lifting hydraulic cylinder for the pressure roller device, so that during the process of the main shaft winding the scrap edge wire, the pressure roller device can be adaptively raised in real time as the diameter of the material on the main shaft increases, so as to ensure that the pressure roller device can always be in rolling contact with the outer periphery of the material on the main shaft, provide sufficient pressure to press and compact the scrap edge of the metal plate and strip wound on the main shaft, and ensure that the scrap edge coil is not loose, so as to make the subsequent transportation, material distribution and unloading processes more convenient and safe, and avoid injuries to personnel; at the same time, during the winding process, the pressure roller device realizes directional compression of the scrap edge wire, which ensures the winding quality while avoiding the loose scrap edge wire causing obstacles to the operation of the main shaft, thereby improving the efficiency and reliability of the scrap edge winding operation.

[0091] (2) The use of a pressure roller device to dynamically press the outer periphery of the coil on the main shaft in real time can reduce the shaking caused by the rotation of the main shaft, thereby reducing the vibration amplitude and noise of the entire equipment, which is beneficial to improving the service life of the equipment.

[0092] (3) The existing metal plate and strip scrap winding device has a poor safety design concept and poor overall equipment safety. Based on this, this solution installs a safety grating on the left and right archways on the scrap edge inlet side. The safety grating is connected to the motor of the rotating device through a controller. When the safety grating detects that an object enters the light curtain detection range between the left and right archways, the controller can immediately control the motor to stop, avoiding casualties caused by human misoperation, and effectively improving the safety of use and operational installation of the winding equipment.

[0093] (4) This solution also provides a travel switch in front of the guide column support. The travel switch can monitor the distance between the sliding seat and the guide column in real time, preventing the spindle from damaging the left large plate and its sleeve when moving left, and preventing the sliding seat from damaging the guide column support at the right end of the guide column when moving right. The provision of the travel switch further improves the reliability of the equipment operation.

[0094] (5) The overall structure of this solution is simple and reasonable, and the manufacturing cost is low, which greatly saves production costs. The existing copper plate and strip waste edge winding device has high overall energy consumption. This solution uses multiple groups of hydraulic cylinders as the main drive of the equipment, which has the advantages of lower cost and lower energy consumption.

[0095] (6) This solution has an ingenious structural design, a compact size, and full functions. It can realize the semi-automatic operation of the scrap edge coiling operation, improve the scrap edge coiling efficiency, and ensure the health and safety of the workers. It can fully meet the scrap edge coiling needs of our company after the copper strip is sheared.

[0096] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
