Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a steel strip winding mechanism that facilitates transportation. Background Technology

[0002] A winding machine is an industrial piece of equipment widely used in printing, packaging, and metal processing, primarily for winding long strips of material into rolls. For winding machines carrying lighter rolls, the shaft supporting and driving the roll can be suspended on one side, such as for plastic or fiberglass rolls. However, for heavier rolls like steel strips, this suspended shaft leads to structural instability and poses a safety risk of slippage. While existing technologies include tensioning mechanisms on the shaft, these need to be released during unloading, increasing the risk of the roll slipping. Furthermore, while some machines include supports at the shaft ends, these are structurally redundant and can obstruct the movement of AGVs or forklifts, especially during transport. Therefore, this invention improves and innovates the structure of traditional winding machines by providing a sliding support connection mechanism. This allows space to be created when AGVs need to transport the roll, provides stable support during winding operations, and improves the level of production automation. Utility Model Content

[0003] The purpose of this utility model is to provide a winding mechanism that facilitates loading and unloading of AGVs, and to solve the problem that AGV trolleys cannot cooperate with winding machines to load, unload and transfer material rolls in the prior art. The technical solution is to propose a sliding support connecting seat by improving the structure of the winding machine.

[0004] Technical solution: A steel strip winding mechanism that facilitates transfer includes a frame, a motor on the frame, the motor driving a rotating shaft for placing a steel strip coil, and a support slide at the steel strip coil removal end of the winding mechanism.

[0005] The support slide is mounted on the frame and includes a sliding beam that can move at the steel strip coil take-out end. The sliding beam is controlled to slide by an actuator, and a lifting device for supporting the end of the drive shaft is provided on the sliding beam. A pair of support wheels are provided on the top of the lifting device. The lifting device is used to control the lifting of the support wheels after the support wheels reach the position of supporting the end of the drive shaft.

[0006] Furthermore, the bottom of the frame is provided with a sliding base, including guide rails located on both sides of the frame. A sliding base plate is fixedly connected to the guide rails by a number of sliders. The frame is fixed on the sliding base plate, and the frame can move with the sliding base plate.

[0007] The frame can move along the guide rail under the action of the drive mechanism.

[0008] Furthermore, a reducer is installed at the output end of the motor, and the shaft is connected to it via a sprocket and chain drive.

[0009] Furthermore, a tensioning wheel is installed on the rotating shaft to support the inner ring of the steel strip coil.

[0010] Furthermore, the slide is located on one side of the guide rail, and a bayonet seat is provided on the other side of the guide rail. The bayonet seat is used to support and fix the end of the sliding crossbeam. The bayonet seat is provided with a protrusion facing the direction of movement of the sliding crossbeam, and the protrusion matches the shape of the concave part of the sliding crossbeam.

[0011] The bayonet mount is equipped with a proximity switch for detecting whether the sliding crossbeam has reached the designated position;

[0012] The proximity switch is used to send a stop signal to the actuator and / or a motion signal to the lifting device to control its lifting and lowering to contact the drive shaft.

[0013] The bayonet seat includes bullseye ball bearings to reduce friction on the sliding crossbeam.

[0014] The aforementioned actuator and lifting device both include a cylinder, hydraulic cylinder, or electric cylinder as the driving mechanism.

[0015] Furthermore, the steel strip winding mechanism is equipped with an auxiliary correction mechanism, which includes a pressure roller and a pressure plate located around the steel strip coil. The pressure roller and pressure plate are rotatably connected to the frame via a pressure shaft rod. The pressure shaft rod is controlled by a cylinder to rotate and open. The bottom of the cylinder and the end of the telescopic rod are movably mounted on the frame and connecting parts.

[0016] A torsion spring is fitted on the pressure shaft rod, and the torsion spring is used to control the pressure roller to adhere to the steel strip coil.

[0017] Beneficial effects: This utility model, through its movable sliding support connecting seat design, facilitates the integration of AGVs with winding machines, directly connecting the material rolls and tensioning rollers, which helps improve work efficiency and enhance the level of automation in workshop production. Furthermore, the sliding support connecting seat can be automatically opened and closed via motor programming control, enabling integration with automated production lines and reducing the workload of material roll transfer operations.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figure 1-4 This utility model addresses the technical problem of inconvenience in transporting thin steel strip coils using AGVs after winding by a thin steel strip winding machine, and proposes a steel strip winding mechanism that facilitates transportation. The mechanism includes a frame 1, with a motor 3 mounted on the top of the frame 1. A reducer (cycloidal pinwheel reducer) is fixedly connected to the output shaft of the motor 3 to reduce or control its speed. A sprocket is mounted on the output shaft of the reducer, which in turn drives a sprocket on a rotating shaft 4 via a chain. A tension wheel is mounted on the rotating shaft 4, the structure of which can be found in [reference needed]. Figure 2As shown, the device includes a turntable 401 with a slotted groove 402 to restrict the arc-shaped plate 407 to move only up and down. A support bar is provided on the inner side of the arc-shaped plate 407, and the support bar is movably connected to a connecting plate 406. The other side of the connecting plate 406 is rotatably connected to an upper plate 404. The upper plate 404 is mounted on a drive shaft 4 via several hollow bushings 405, and the end bushings 403 at the ends of the upper plate 404 are fixed to the end of the drive shaft 4. This allows the upper plate 404 to move towards the turntable 401 when the end bushings 403 are turned (manually). The hollow bushings 405 also move towards the turntable 401. Because the turntable 401 is fixed and the slotted groove 402 restricts movement, the connecting plate 406 expands its angle with the drive shaft 4, meaning the arc-shaped plate 407 expands outward, providing expansion support for the inside of the steel strip coil 2. Furthermore, the support in each direction is linked and expands synchronously.

[0027] Combination Figure 3-5 As shown, the mechanism provided by this utility model sets the frame 1 as a sliding structure, including a sliding base 6 located at the bottom of the frame 1, and two parallel guide rails 601. To ensure structural stability and prevent changes in the spacing between the two guide rails 601, connecting rods can be provided at their ends for fixation. Combined with... Figure 3 As shown, guide rail 601 is used for the movement of slider 602, slider 602 is used to mount upper sliding base plate 603, and frame 1 and its related components can be fixed on sliding base plate 603. We can use direct drive of sliding base plate 603 to control the overall movement of frame 1, and a drive mechanism 7 can be provided on the side of sliding base plate 603, such as... Figure 4 As shown, the drive mechanism 7 can be a pneumatic cylinder or a hydraulic cylinder, such as... Figure 4 As shown, the telescopic rod can be fixed to the side push block 703 of the sliding base plate 603. In order to improve the stability of the drive and increase the stroke, an extension slide 702 is provided for the telescopic rod of the cylinder to adjust it, which can also prevent it from deviating.

[0028] Further integration Figure 3 and Figure 5We fix a support slide 5 at the leading edge of the guide rail 601 on one side (located at the take-out end of the steel strip coil 2). The support slide 5 sets the sliding beam 501 through the support slide slider 503 and the slide rail 504. Specifically, the support slide 5 first fixes the support slide slider 503, and then sets the slide rail 504 based on the support slide slider 503. The slide rail 504 is located at the bottom of the sliding beam 501, thereby realizing the sliding of the sliding beam 501. A locking mechanism is provided to control the locking after the sliding reaches the designated position. The sliding method can be manual or automatic. For automatic, a cylinder or electric cylinder can be arranged along the slide rail 504 at the bottom of the sliding beam 501. The cylinder or electric cylinder is fixed to the bottom of the sliding beam 501, and its telescopic rod is connected and fixed to the support slide slider 503 or the support slide 5. The extension and retraction of the telescopic rod can realize the sliding control. By analogy with this mechanism, those skilled in the art may make further improvements in some embodiments as follows, and such improvements or optimizations should also fall within the scope of protection of this utility model. Specifically:

[0029] 1. Replace the support block slider 503 with another sliding plate, the slide groove on which matches the slide rail 504 at the bottom of the sliding beam 501;

[0030] 2. In order to realize the movement of the sliding beam 501, a ball screw module is set on the guide rail 601, which can be an extension base to the side of the steel strip that is not obstructed when picking up and placing it.

[0031] 3. Rollers are used to control the movement of the sliding beam 501. For example, a drive roller is provided on the support slide 5 to contact the bottom of the sliding beam 501. The movement of the sliding beam 501 is controlled by rotating the drive roller.

[0032] The movement of the sliding beam 501 is to provide support for the end of the drive shaft 4 when the steel strip coil has a large mass. Specifically, the sliding beam 501 is equipped with a hydraulic cylinder 502. Taking a position in the middle of the sliding beam 501 as an example, when the sliding beam 501... Figure 3 The sliding beam 501 moves to the position shown in the diagram. A proximity switch on the bayonet 8 detects the arrival of the sliding beam 501 and sends a signal to the controller of the hydraulic cylinder 502. The hydraulic cylinder 502 actuates, raising the support wheel 505. The support wheel 505 is a non-powered device; it drives the rotating shaft 4 via a set of support wheels 505 (which may be bearings). After processing is completed, the hydraulic cylinder 502 retracts downwards, lowering the support wheels 505, and the sliding beam 501 can then move to the desired position. Figure 3 The steel strip coil 2 is moved to the left so that the removal of the steel strip coil 2 is not affected.

[0033] The auxiliary correction mechanism 9 in this invention is designed to assist in positioning the ultra-thin steel strip during the winding process. For example, the steel strip itself has a certain degree of toughness; without compression, the coil will become loose. This invention uses the auxiliary correction mechanism 9 to improve stability and winding quality. Figure 1 As shown, we can see the pressure roller 901 and the pressure shaft 902. A torsion spring is installed at the connection between the pressure shaft 902 and the frame 1. This spring controls the pressure roller 901 to press downwards against the material roll. After the thin steel strip is coiled, the drive cylinder overcomes the force of the torsion spring to rotate the pressure shaft 902, thereby controlling the pressure roller 901 to lift upwards. It should be noted that both ends of the drive cylinder are rotatable connections; for example, the connecting rod to the pressure shaft 902 is rotatable. Figure 1 As shown, the drive cylinder also needs to be rotatably connected to the side of the frame 1, such as... Figure 6 As shown.

[0034] A specific application of this utility model is as follows: the take-up drum is placed on the drive shaft 4, and the shaft end sleeve 403 and its adjustment part at its end are adjusted to control the tension wheel 4 to open so as to support the take-up drum. After the tension wheel is locked, a safety protection blocking block is added to the shaft 4. This process can also be carried out by AGV vehicle transportation and placement. The drive cylinder releases the control force on the pressure rod 902, the pressure roller 901 moves downward to fit the material roll, one end of the sliding beam 501 moves to the position of the bayonet seat 8, the hydraulic cylinder 502 controls the support wheel 505 to rise to support the end of the drive shaft 4, the drive shaft 4 starts to wind the material under the action of the motor, after completion, the drive cylinder controls the pressure rod 902 to rotate, thereby releasing the space above the steel strip material roll 2, one end of the sliding beam 501 retracts from the position of the bayonet seat 8, releasing the control of the steel strip material roll 2 take-off end, which can facilitate the AGV vehicle to transport. Furthermore, in this utility model, the cylinder 701 can also control the frame 1 to move forward as a whole, which makes it more convenient to pick up and unload the steel strip material roll 2.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
