Description

Technical Field

[0001] The present invention belongs to the technical field of brush strip recycling, and particularly relates to a steel strip winding device. Background Art

[0002] With the continuous strengthening of environmental awareness, the existing rust removal treatment of steel has gradually replaced the traditional pickling method. A method of grinding with a brush strip can effectively remove rust. A file with the application number 201921666907.6 discloses a descaling roll, which includes a roll core around which a coiled belt is wound; a plurality of grinding rods are fixed along the length direction of the coiled belt inside the coiled belt; each grinding rod is folded in half from the middle, and a metal wire is passed through the middle of the folded grinding rod; the coiled belt can be vividly called a steel strip, the grinding rod can also be called an abrasive wire, and the metal wire is equivalent to a steel wire, as Figure 9 shown, the steel strip, the abrasive wire and the steel wire are connected to form a brush strip. As the abrasive wire on the brush strip is consumed and worn, a new brush strip needs to be replaced for continuous grinding, and the worn brush strip can be recycled.

[0003] A Chinese patent with the application number CN202011576815.6 discloses a brush strip recycling device. First, the steel wire inside the steel strip is drawn out and wound around a steel wire winding disc, then the steel strip is flanged and pressed by multiple groups of shaping wheels, and then the steel strip is cut into segments for recycling. Although recycling can be achieved, the integrity of the recycled steel strip is poor and it still needs to be packed. Moreover, due to the certain rigidity of the steel strip, the loss of materials such as cutting knives is also large, which further increases the production cost. This method has gradually been phased out. Although there is also a method of winding the steel strip by a winding shaft, due to the structure of the steel strip itself, it has a certain volume and weight. After winding, the volume and weight of the steel strip are both large, and it is difficult to unload manually, which will reduce the production efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a steel strip winding device that can automatically adapt to the feeding speed of the steel strip, continuously wind, and can automatically discharge the material after winding, with simple and convenient operation, greatly improving the production efficiency.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A steel strip winding device includes a steel strip winding base. The steel strip winding base includes a steel strip winding bottom plate connected to the machine base and a steel strip release side plate vertically connected to one end of the steel strip winding bottom plate. A pulling port is formed in the middle position of the steel strip release side plate. There is a pulling port on one side of the steel strip winding base, a winding area is formed in front of the steel strip winding base, and a retreat area is formed behind the steel strip winding base; a steel strip winding component for winding the steel strip is provided in the winding area. The steel strip winding component has a steel strip winding disc and multiple parallel steel strip winding support rods connected to the steel strip winding disc. A winding driving part for driving the steel strip winding component to rotate and wind the steel strip is provided in the retreat area; a material retreat driving part for driving the winding driving part to move axially along the pulling port is also provided in the retreat area; in the working state, the winding driving part drives the steel strip winding component to wind. After winding is completed, the material retreat driving part drives the winding driving part to move, thereby driving the steel strip winding component to move into the retreat area along the axial direction of the pulling port, and the wound steel strip is unloaded under the pressing of the steel strip winding base.

[0007] The steel strip winding base provides fixed installation points for each component. The winding area formed in front of the steel strip release side plate is the working area for winding the steel strip, and the retreat area formed behind the steel strip release side plate is the area for the steel strip winding component and the winding driving part to retreat, so that the steel strip can be unloaded under the resistance of the steel strip release side plate after winding is completed. In the working state, the steel strip winding component is located in the winding area and winds the steel strip under the drive of the winding driving part; when winding is completed and it enters the unloading state, the material retreat driving part drives the steel strip winding device and the winding driving part to move from the pulling port to the retreat area, and the wound steel strip is unloaded under the limiting resistance of the steel strip release side plate.

[0008] Preferably, a steel strip unloading ring that rotates synchronously with it is further provided on the outer side of the circumferential surface of the steel strip winding disc. Relative sliding can occur between the steel strip unloading ring and the steel strip winding support rods. The steel strip unloading ring and the steel strip release side plate are relatively fixed along the unloading direction; a material retreat chute is formed by inward contraction along the length direction of the top surface of the steel strip winding support rod, and multiple material retreat protrusions adapted to the material retreat chute are provided on the inner circumferential surface of the steel strip unloading ring; the steel strip unloading ring has two states, a winding state and an unloading state; in the winding state, the steel strip winding support rods drive the steel strip unloading ring to rotate together when winding the steel strip; in the unloading state, the steel strip winding support rods move into the retreat area along the axial direction of the steel strip unloading ring, and the wound steel strip on the steel strip winding support rods is unloaded under the resistance of the steel strip unloading ring.

[0009] The steel strip unloading ring can rotate synchronously with the steel strip winding disc when the steel strip winding disc rotates. The unloading protrusions provided on the inner circumferential surface of the steel strip unloading ring cooperate with the retracted unloading sliding grooves on the steel strip winding support rod for sliding. On the one hand, it can play a role in limiting and guiding the steel strip winding disc. On the other hand, it can also prevent the steel strip from getting stuck in the gap between the steel strip winding disc and the steel strip release side plate during the process of winding the steel strip, causing blockage and affecting the continuous winding of the steel strip. On the third hand, it can also reduce the possible friction between the steel strip and the steel strip release side plate during the winding process. In the winding state, the steel strip winding disc rotates to wind the steel strip through the steel strip winding support rod, and the steel strip unloading ring can rotate together with the steel strip winding disc under the limitation of the unloading sliding groove. When entering the unloading state after the winding is completed, the relative fixation of the steel strip unloading ring and the steel strip release side plate in the unloading direction makes the steel strip unloading ring not move in the unloading direction during unloading. However, the relative sliding between the steel strip unloading ring and the steel strip winding support rod enables the steel strip winding disc and the steel strip winding support rod to retreat from the drawing port to the retreat area under the cooperation of the unloading protrusion and the unloading sliding groove. During the retreat process, the wound steel strip is unloaded under the limitation and resistance of the steel strip unloading ring.

[0010] Preferably, the relative fixation of the steel strip unloading ring and the steel strip release side plate in the unloading direction means that: a unloading fixing part is provided on the front side of the steel strip release side plate, and an extension part is provided on the outer circumferential surface of the steel strip unloading ring. The extension part is rotatably connected within the unloading fixing part. The unloading fixing part includes a unloading ring-shaped base fixedly connected to the front side of the steel strip release side plate. The unloading ring-shaped base is evenly provided with a plurality of placement openings along its circumference. A plurality of rolling bearings are provided in the placement openings. A ring-shaped pressing plate is further connected to the front side of the unloading ring-shaped base. A accommodation interval is left between the unloading ring-shaped base and the ring-shaped pressing plate, and the extension part can rotate within this accommodation interval.

[0011] The steel strip unloading ring and the steel strip release side plate are fixedly installed through the unloading fixing part. The unloading ring-shaped base is fixedly connected to the front side of the steel strip release side plate. Then, an accommodation interval is formed between the ring-shaped pressing plate connected to the unloading ring-shaped base and the unloading ring-shaped base. The steel strip unloading ring is rotatably connected within the accommodation interval through the extension part provided on its outer circumferential surface. The unloading ring-shaped base and the ring-shaped pressing plate jointly limit the steel strip unloading ring in the unloading direction, ensuring the relative fixation of the steel strip unloading ring and the steel strip release side plate, and at the same time allowing the steel strip unloading ring to rotate relative to the steel strip winding disc. The ring-shaped pressing plate and the unloading ring-shaped base, on the one hand, provide connection points for the rolling bearings and the steel strip unloading ring, on the other hand, they also limit them, and the provided accommodation interval also allows the steel strip unloading ring to rotate within the accommodation interval.

[0012] Preferably, a plurality of steel strip winding limiting rollers for restricting the steel strip winding radius are further connected to the steel strip winding disc, and the ends of the plurality of steel strip winding support rods are connected with steel strip winding flanges for strengthening the steel strip winding support rods.

[0013] The steel strip winding limiting roller can limit the radius of the steel strip winding, preventing the winding from being too large or too small, which is not conducive to subsequent stacking and handling. The size of the winding radius can be intuitively judged through the steel strip winding limiting roller. Since the wound steel strip has a certain weight, the steel strip winding flange can reinforce the steel strip winding support rod to protect the stable progress of the winding.

[0014] Preferably, the steel strip winding assembly includes a steel strip winding shaft driven to rotate by a winding drive part. A steel strip winding friction disc is key-connected to the steel strip winding shaft, and a steel strip winding disc is also rotatably connected to the steel strip winding shaft on the front side of the steel strip winding friction disc. A friction plate is provided between the steel strip winding friction disc and the steel strip winding disc. A pressing mechanism for pressing the steel strip winding disc, the friction plate and the steel strip winding friction disc is also provided on the steel strip winding shaft. During operation, the pressing mechanism pre-presses the steel strip winding disc, the friction plate and the steel strip winding friction disc to generate friction force between the three. The winding drive part drives the steel strip winding shaft to drive the steel strip winding friction disc to rotate. Under the action of the friction force, the steel strip winding disc and the steel strip winding support rod rotate to wind the steel strip. The steel strip winding radius continuously increases during the winding process, and the winding reaction force also increases accordingly. When the winding reaction force is less than the friction force, the steel strip winding support rod winds the steel strip normally. When the winding reaction force is greater than the friction force, relative rotation occurs between the steel strip winding disc and the steel strip winding friction disc to avoid the steel strip being broken due to excessive winding reaction force.

[0015] When the steel strip winding support rod winds the steel strip, as the winding progresses, the winding radius continuously expands, while the feeding speed of the steel strip remains unchanged. At this time, the steel strip will generate a winding reaction force to resist the winding. As the winding radius continuously increases, the winding reaction force also continuously increases. When it increases to a certain extent, the steel strip will be broken, resulting in the inability to continue winding. However, a friction plate is provided between the steel strip winding disc and the steel strip winding friction disc, and the steel strip winding disc and the steel strip winding friction disc are pressed together by the pressing mechanism to generate friction force between the two. The steel strip winding friction disc rotates synchronously with the steel strip winding shaft, and the steel strip winding disc is rotatably connected to the steel strip winding shaft. When the winding reaction force is less than the friction force, the steel strip winding disc is driven by the steel strip winding friction disc to rotate together to wind the steel strip. When the winding reaction force is greater than the friction force, relative rotation can occur between the steel strip winding disc and the steel strip winding friction disc, thus avoiding the steel strip from being broken.

[0016] Preferably, a sleeve sleeved outside the steel strip winding shaft is further provided at the middle position of the steel strip winding disc, and external threads are provided at the end of the steel strip winding shaft; a boss extends out on the inner side wall of the end of the sleeve connected to the steel strip winding disc; the pressing mechanism includes a deep groove ball bearing, a thrust ball bearing and a bearing pressing piece sleeved on the steel strip winding shaft arranged in sequence on one side of the boss, a spring sleeved on the steel strip winding disc is further provided on one side of the bearing pressing piece, a spring pressing piece is provided on one side of the spring, and a nut connected to the external threads at the end of the steel strip winding shaft is provided outside the spring pressing piece; screwing the nut can adjust the pressing force between the spring on the steel strip winding disc, the friction plate and the steel strip winding friction disc, and further adjust the friction force between the steel strip winding disc, the friction plate and the steel strip winding friction disc.

[0017] The purpose of the pressing mechanism is to adjust the pressing force between the steel strip winding disc and the steel strip winding friction disc, and further achieve the purpose of adjusting the friction force, which can be applicable to different production environments and requirements. During adjustment, by screwing the nut, the nut presses the spring pressing piece, and the spring pressing piece presses the spring to deform it to generate elastic force. The elastic force further presses the thrust ball bearing and the deep groove ball bearing on one side of the boss, and then generates a pressing force on the steel strip winding disc. The pressing force is adjusted by the tightness of the nut screwing.

[0018] Preferably, the material discharging driving part includes a hydraulic cylinder hinged on the machine base, and the piston rod of the hydraulic cylinder is connected to the lower end of the winding driving part; a slide rail is provided on the top surface of the steel strip winding bottom plate, and the winding driving part is slidably connected to the slide rail.

[0019] Preferably, the winding driving part includes a motor bottom plate slidably connected to the slide rail, a reduction gearbox is connected to the motor bottom plate, and the output end of the reduction gearbox is connected to the steel strip winding shaft; the reduction gearbox is further connected to a reduction motor.

[0020] The material discharging driving part and the winding driving part are independent of each other. The material discharging driving part can drive the winding driving part and the steel strip winding assembly to move together. The material discharging is realized by driving the winding driving part to move along the material discharging direction on the slide rail through the hydraulic cylinder.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The steel strip is wound in the winding area by driving the steel strip winding assembly through the winding driving part. After winding is completed, the material discharging driving part drives the winding driving part and the steel strip winding assembly to move into the retreat area along the axial direction of the drawing opening, so that the steel strip wound by the steel strip winding assembly is discharged under the resistance of the steel strip release side plate.

[0023] The setting of the steel strip unloading ring can, on the one hand, play a role in limiting and guiding the steel strip winding disc. On the other hand, the cooperation between the unloading protrusions provided on the inner circumferential surface of the steel strip unloading ring and the unloading chute on the steel strip winding support rod can prevent the steel strip from being stuck in the gap between the steel strip winding disc and the unloading fixing part or the steel strip release side plate during the winding of the steel strip, causing blockage. On the other hand, the steel strip unloading ring can rotate synchronously with the steel strip winding disc, reducing the friction between the steel strip and the annular pressing plate when winding the steel strip. The setting of the pressing mechanism is to adjust the pressing force, and then adjust the friction force between the steel strip winding disc and the steel strip winding friction disc, so that the steel strip winding disc and the steel strip winding friction disc can rotate relatively, avoiding the steel strip from being broken by the increasing winding reaction force when the winding radius of the steel strip increases.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] In this embodiment, a steel strip winding device is specifically disclosed, such as Figures 1-9 As shown, its specific structure includes a steel strip winding seat 601, the steel strip winding seat 601 includes a steel strip winding bottom plate 602 connected to the machine base 1 and a steel strip release side plate 603 vertically connected to one end of the steel strip winding bottom plate 602, a pull-out opening 608 is opened in the middle of the steel strip release side plate 603, a pull-out opening 608 is provided on one side of the steel strip winding seat 601, a winding area is formed on the front side of the steel strip winding seat 601, and a retreat area is formed on the rear side of the steel strip winding seat 601; a steel strip winding assembly for winding the steel strip is provided in the winding area, and the steel strip winding assembly has a steel strip winding reel 610 And connected to the steel strip winding disk 610 are multiple parallel steel strip winding support rods 619, and the retreat area is provided with a winding drive part for driving the steel strip winding assembly to rotate and wind the steel strip; the retreat area is also provided with a material unloading drive part that drives the winding drive part to move axially along the withdrawal port 608; in the working state, the winding drive part drives the steel strip winding assembly to wind, and after the winding is completed, the material unloading drive part drives the winding drive part to move and then drives the steel strip winding assembly to move along the axial direction of the withdrawal port 608 toward the retreat area, and the wound steel strip is unwound under the pressure of the steel strip winding seat 601.

[0036] When winding a steel coil, the steel strip release side plate 603 vertically connected to one end of the steel strip winding bottom plate 602 divides into two areas, a winding area in front of the steel strip release side plate 603 and a retreat area behind it. First, connect one end of the steel strip to the steel strip winding component and wind the steel strip by driving the steel strip winding disc 610 and the steel strip winding support rod 619 through the winding drive part in the winding area. After winding, the unloading drive part drives the winding drive part and the steel strip winding component to move into the retreat area along the axial direction of the drawing port 608, so that the wound steel strip is unloaded under the blocking and limiting of the steel strip release side plate 603.

[0037] As Figures 7-8 shown, a steel strip unloading ring 618 that rotates synchronously with it is further provided on the outer side of the circumferential surface of the steel strip winding disc 610. Relative sliding can occur between the steel strip unloading ring 618 and the steel strip winding support rod 619, and the steel strip unloading ring 618 and the steel strip release side plate 603 are relatively fixed along the unloading direction; a unloading chute 620 is formed by inward contraction along the length direction on the top surface of the steel strip winding support rod 619, and a plurality of unloading protrusions 621 adapted to the unloading chute 620 are provided on the inner circumferential surface of the steel strip unloading ring 618; the steel strip unloading ring 618 has two states, a winding state and an unloading state; in the winding state, the steel strip winding support rod 619 drives the steel strip unloading ring 618 to rotate together when winding the steel strip; in the unloading state, the steel strip winding support rod 619 moves into the retreat area along the axial direction of the steel strip unloading ring 618, and the wound steel strip on the steel strip winding support rod 619 is unloaded under the blocking of the steel strip unloading ring 618.

[0038] In the specific process of winding the steel strip, the steel strip will wind and be wound around the steel strip winding support rod 619 as the steel strip winding disc 610 rotates. A steel strip unloading ring 618 is provided on the outer circumference surface of the steel strip winding disc 610. The cooperation between the unloading protrusions 621 provided on the inner circumference surface of the steel strip unloading ring 618 and the unloading chute 620 on the steel strip winding support rod 619 enables the steel strip winding disc 610 to drive the steel strip unloading ring 618 to rotate together when rotating. During the winding process, the unloading protrusions 621 of the steel strip unloading ring 618 are engaged into the retracted unloading chute 620. Therefore, it can effectively prevent the steel strip from being stuffed into the gap between the steel strip winding disc 610 and the steel strip release side plate 603. On the other hand, it can also limit the wound steel strip to prevent the steel strip from rubbing against the steel strip release side plate 603, thus affecting the winding efficiency. After the winding is completed, since the steel strip unloading ring 618 and the steel strip release side plate 603 are relatively fixed, but at the same time, the steel strip unloading ring 618 and the steel strip winding support rod 619 can slide relative to each other through the cooperation of the unloading protrusions 621 and the unloading chute 620, enabling the steel strip winding disc 610 to move towards the retreat area along the axial direction of the drawing port 608, while the steel strip unloading ring 618 does not move. At this time, the steel strip unloading ring 618 can press and limit the wound steel strip to achieve the unloading action.

[0039] As Figures 5-8 shown, the relative fixation between the steel strip unloading ring 618 and the steel strip release side plate 603 in the unloading direction means that: a unloading fixing part 628 is provided on the front side of the steel strip release side plate 603, and an extension part 630 is provided on the outer circumference surface of the steel strip unloading ring 618. The extension part 630 is rotationally connected inside the unloading fixing part 628; the unloading fixing part 628 includes an unloading annular base 616 fixedly connected to the front side of the steel strip release side plate 603. The unloading annular base 616 is evenly provided with a plurality of placement openings 640 along its circumference. A plurality of rolling bearings 641 are provided in the placement openings 640. An annular pressing plate 617 is also connected to the front side of the unloading annular base 616. A accommodation interval is left between the unloading annular base 616 and the annular pressing plate 617, and the extension part 630 can rotate within this accommodation interval. The unloading annular base 616 and the annular pressing plate 617 constitute the unloading fixing part 628.

[0040] When installing the steel strip unloading ring 618, first install the unloading annular base 616 on the front side of the steel strip release side plate 603, press the extension part 630 provided on the outer circumference surface of the steel strip unloading ring 618 onto the unloading annular base 616, and then press the annular pressing plate 617 onto the extension part 630. The accommodation interval left between the unloading annular base 616 and the annular pressing plate 617 can accommodate the extension part 630, so that the steel strip unloading ring 618 can rotate but cannot move in the unloading direction. The extension part 630 can also cooperate with the rolling bearings 641 to reduce the friction generated during rotation.

[0041] As Figure 3 and 5 shown, a plurality of steel strip winding limiting rollers 623 for limiting the winding radius of the steel strip are further connected to the steel strip winding disk 610, and a steel strip winding flange 627 for strengthening the steel strip winding support rod 619 is connected to the ends of the plurality of steel strip winding support rods 619.

[0042] It is felt that due to its large volume and weight, in order to ensure the smooth and stable winding process, the steel strip winding flange 627 can play a role in strengthening the steel strip winding support rod 619 and prevent the steel strip winding support rod 619 from being broken due to gravity.

[0043] As Figures 7-8 shown, the steel strip winding assembly includes a steel strip winding shaft 607 driven to rotate by a winding driving part. A steel strip winding friction disk 609 is key-connected to the steel strip winding shaft 607, and a steel strip winding disk 610 is also rotatably connected to the steel strip winding shaft 607 in front of the steel strip winding friction disk 609; a friction plate 611 is provided between the steel strip winding friction disk 609 and the steel strip winding disk 610, and a pressing mechanism for pressing the steel strip winding disk 610, the friction plate 611 and the steel strip winding friction disk 609 is further provided on the steel strip winding shaft 607; during operation, the pressing mechanism pre-presses the steel strip winding disk 610, the friction plate 611 and the steel strip winding friction disk 609 to generate frictional force between the three. The winding driving part drives the steel strip winding shaft 607 to drive the steel strip winding friction disk 609 to rotate. Under the action of the frictional force, the steel strip winding disk 610 and the steel strip winding support rod 619 rotate to wind the steel strip. The winding radius of the steel strip continuously increases during the winding process, and the winding reaction force will also increase accordingly; when the winding reaction force is less than the frictional force, the steel strip winding support rod 619 winds the steel strip normally; when the winding reaction force is greater than the frictional force, relative rotation occurs between the steel strip winding disk 610 and the steel strip winding friction disk 609 to prevent the winding reaction force from being too large and breaking the steel strip.

[0044] The setting of the pressing mechanism is to adjust the magnitude of the frictional force between the steel strip winding friction disk 609 and the steel strip winding disk 610 so that the device is more suitable for various production environments and requirements. Its principle is to change the magnitude of the frictional force between the two by adjusting the magnitude of the pressing force between the steel strip winding friction disk 609 and the steel strip winding disk 610. A friction plate 611 is also provided between the two. On the one hand, it is to facilitate the regulation of the magnitude of the frictional force, and on the other hand, it can also prevent direct contact between the steel strip winding friction disk 609 and the steel strip winding disk 610 from causing wear.

[0045] When winding the steel strip, the winding radius of the steel strip is constantly increasing, while the feeding speed of the steel strip remains unchanged. The steel strip winding shaft 607 and the steel strip winding friction disc 609 key-connected thereto always rotate at a constant speed. Therefore, a winding reaction force will be generated by the steel strip to resist winding. When the winding reaction force is less than the frictional force, the steel strip winding disc 610 will be driven by the steel strip winding friction disc 609 to rotate together, realizing the winding of the steel strip; when the winding reaction force is greater than the frictional force, relative rotation will occur between the steel strip winding disc 610 and the steel strip winding friction disc 609 to prevent the steel strip from being pulled and broken.

[0046] A sleeve 612 sleeved outside the steel strip winding shaft 607 is further provided at the middle position of the steel strip winding disc 610, and an external thread is provided at the end of the steel strip winding shaft 607; a boss 624 extends from the inner side wall of the end of the sleeve 612 connected to the steel strip winding disc 610; the pressing mechanism includes a deep groove ball bearing 625, a thrust ball bearing 626 and a bearing pressing piece 613 sleeved on the steel strip winding shaft 607, which are sequentially arranged on one side of the boss 624. A spring 614 sleeved on the steel strip winding disc 610 is further provided on one side of the bearing pressing piece 613, a spring pressing piece 615 is provided on one side of the spring 614, and a nut connected to the external thread at the end of the steel strip winding shaft 607 is provided outside the spring pressing piece 615; by screwing the nut, the pressing force of the spring 614 on the steel strip winding disc 610, the friction plate 611 and the steel strip winding friction disc 609 can be adjusted, and further the frictional force between the steel strip winding disc 610, the friction plate 611 and the steel strip winding friction disc 609 can be adjusted.

[0047] When it is necessary to increase the frictional force, the nut can be directly tightened, so that the nut presses the spring pressing piece 615, and the spring pressing piece 615 presses the spring 614 in turn. Then the spring 614 deforms to generate an elastic force to press the bearing pressing piece 613, the thrust ball bearing 626 and the deep groove ball bearing 625 toward the boss 624. Through the transmission of force, finally the pressing force presses the steel strip winding disc 610 against the steel strip winding friction disc 609, so as to achieve the effect of increasing the frictional force; similarly, if it is necessary to reduce the frictional force, only the nut needs to be loosened.
