The trimmed scrap is in strip or bar shape and is generally coiled into steel coils for reuse or recycling. Some thicker or harder-to-coil trimmed scrap can be broken up and recycled. During the coiling process of the strip scrap, when uncoiling, the conical drum goes offline, and an annular gap forms between the narrow end of the drum and the drive-side frame. The beginning and end of the coiled material, as well as waste, can enter this gap and cause jamming, affecting normal production. Summary of the Invention

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 2 This invention provides a waste edge material winding device, including a frame 1 and a roll 2. The roll 2 is equipped with a rotary drive unit for driving it to rotate around its own axis and a translation drive unit for driving it to move along the axial direction, which can realize the winding and unwinding of waste edges.

[0025] In one embodiment, the drum 2 travels on the drive-side frame 1.

[0026] Preferably, such as Figure 1 and Figure 2 The aforementioned roll 2 includes a tapered take-up section 21, the cross-sectional area of ​​which gradually increases along the offline direction of the roll 2; this structure can improve the take-up effect on waste edges and is also very convenient for unwinding. Further, as... Figure 1 and Figure 2 The aforementioned roll 2 also includes a straight section 22, which is connected to the large-diameter end of the tapered take-up section 21. The rotary drive unit and translation drive unit can be connected through the straight section 22.

[0027] Preferably, the drum 2 is provided with a sealing mechanism 3 at the passage position on the frame 1. The sealing mechanism 3 is mainly used to seal the annular gap formed between the drum 2 and the frame 1, so as to prevent waste edge, tail, debris and other materials from entering the annular gap and causing jamming, which would affect normal production. This effectively improves the working stability and reliability of the edge-cutting material winding device.

[0028] Furthermore, the sealing mechanism 3 is a telescopic sealing mechanism 3 that can adapt to changes in the cross-section of the drum 2. This structure is particularly suitable for cases where the drum 2 includes a tapered take-up section 21. As the tapered take-up section 21 moves out of the frame 1, the distance between it and the through hole gradually increases, that is, the annular gap gradually increases. Based on the above-mentioned telescopic sealing mechanism 3, it can adapt to changes in the cross-section of the tapered take-up section 21, ensuring continuous sealing, and therefore has very high sealing reliability.

[0029] In one embodiment, such as Figure 3 and Figure 4 The sealing mechanism 3 includes multiple sector-shaped sealing plates 31 that are assembled to form a sealing ring 30, and an expansion and contraction unit for adaptively expanding and contracting the sealing ring 30. Each sealing plate has a movable sealing structure at its joint. The sealing ring 30 can adaptively expand and contract, thus achieving the aforementioned effect of adapting to changes in the cross-section of the drum 2. The movable sealing structure at the joint of the sealing plates ensures the continuity of the seal during the expansion and contraction of the sealing ring 30, resulting in very high sealing reliability.

[0030] In one embodiment, such as Figure 4 The fan-shaped sealing plate 31 has tongue-and-groove portions 313 at both ends. Each pair of adjacent fan-shaped sealing plates 31 are tongue-and-groove joined together to form the movable sealing structure. Specifically, the tongue-and-groove portions 313 at both ends of the fan-shaped sealing plate 31 are defined as the first tongue-and-groove portion and the second tongue-and-groove portion, respectively. The first tongue-and-groove portion of one fan-shaped sealing plate 31 is tongue-and-groove joined to the second tongue-and-groove portion of another fan-shaped sealing plate 31. During the expansion and contraction of the sealing ring 30, the two joined tongue-and-groove portions 313 move relative to each other, achieving a movable sealing effect.

[0031] The length of the tongue and groove portion 313 should meet the requirements of the circumference change during the expansion and contraction of the sealing ring 30. For example, the length of the tongue and groove portion 313 is defined as L, and the number of sector sealing plates 31 is n. nL should not be less than the maximum circumference change during the expansion and contraction of the sealing ring 30.

[0032] Preferably, such as Figure 4 The tongue and groove openings at both ends of the fan-shaped sealing plate 31 are opposite in direction. Based on this design, each fan-shaped sealing plate 31 can adopt the same structure, which facilitates standardized manufacturing.

[0033] In another embodiment, the above-mentioned movable sealing structure may also adopt a corrugated plate or other telescopic component, and the two adjacent sector sealing plates 31 can be connected by the telescopic component, which can also meet the requirements of sealing continuity and reliability.

[0034] In one embodiment, such as Figure 3 and Figure 4The expansion and contraction unit includes multiple sets of damping structures. The number of damping structures is the same as that of the sector-shaped sealing plates 31 and they are configured in a one-to-one correspondence. The damping structures are installed on the frame 1, and the sector-shaped sealing plates 31 are connected to the corresponding damping structures.

[0035] As one of the implementation methods, such as Figure 3 and Figure 4 The damping structure includes a compression spring 33. A guide rod 32 is connected to the sector-shaped sealing plate 31. The guide rod 32 is movably mounted on the frame 1. The compression spring 33 is fitted onto the guide rod 32. One end of the compression spring 33 abuts against the spring action surface on the sector-shaped sealing plate 31 / guide rod 32, and the other end abuts against the spring action surface on the frame 1. The force of the compression spring 33 presses the sector-shaped sealing plate 31 tightly onto the drum 2.

[0036] In one embodiment, such as Figure 3 and Figure 4 The aforementioned sector-shaped sealing plate 31 includes a guide bushing 312 and two plate segments 311, which are connected to the two sides of the guide bushing 312 respectively. The guide bushing 312 is connected to the guide rod 32.

[0037] Preferably, the guide bushing 312 and the guide rod 32 are detachably connected, including but not limited to the following structure: the guide rod 32 is fixed to the guide bushing 312 by threads, and can be locked and prevented from loosening by the end nut 321 and the washer.

[0038] An annular baffle can be coaxially arranged inside the guide sleeve 312. The inner ring of the annular baffle has a threaded hole for threaded connection with the guide rod 32. The compression spring 33 can abut against the annular baffle. Furthermore, the annular baffle is located in the middle section of the guide sleeve 312, thus forming shaft cavities on both sides. The end nut 321 is located in one shaft cavity, and the compression spring 33 can extend into the other shaft cavity and abut against the annular baffle. This method can further improve the smoothness of the movement of the sector-shaped sealing plate 31.

[0039] Preferably, such as Figure 1 , Figure 2 as well as Figure 5 and Figure 6 An annular sealing seat 11 is provided on the frame 1, and the sealing mechanism 3 is installed on the annular sealing seat 11.

[0040] Among them, such as Figure 5 and Figure 6Multiple movable grooves 111 are correspondingly formed on the annular sealing seat 11 to accommodate each sector-shaped sealing plate 31, and the groove depth meets the movement requirements of the sector-shaped sealing plate 31. The guide rod 32 passes through the annular sealing seat 11 and can move relative to the annular sealing seat 11, thereby driving the sector-shaped sealing plate 31 to move within the movable groove 111. The movable groove 111 can be adapted to the guide bushing 312, thereby guiding the movement of the guide bushing 312 and improving the stability of the movement of the sector-shaped sealing plate 31. In addition, a guide hole 112 is provided at the bottom of the movable groove 111 for the guide rod 32 to pass through and to accommodate the compression spring 33. Correspondingly, the guide hole 112 is preferably a stepped hole, with the diameter of its large-diameter section adapted to the diameter of the compression spring 33 and the diameter of its small-diameter section adapted to the diameter of the guide rod 32. The other end of the compression spring 33 abuts against the stepped surface of the stepped hole.

[0041] In one embodiment, such as Figures 1-4 The guide rod 32 has a first limiting part 322 at the end away from the fan-shaped sealing plate 31, and a second limiting part suitable for cooperating with the first limiting part 322 is provided on the frame 1. In the configuration where the guide rod 32 passes through the annular sealing seat 11, the first limiting part 322 is preferably provided on the exposed shaft section of the guide rod 32, and the outer wall of the annular sealing seat 11 can correspondingly form the aforementioned second limiting part. Based on the above structure, on the one hand, the maximum travel of the fan-shaped sealing plate 31 can be limited, and on the other hand, the guide rod 32 and the fan-shaped sealing plate 31 can be prevented from detaching from the frame 1, thereby ensuring sealing reliability and equipment safety.

[0042] More preferably, the position of the first limiting part 322 on the guide rod 32 is adjustable and the adjustment direction is parallel to the axial direction of the guide rod 32, and / or the position of the second limiting part on the frame 1 is adjustable and the adjustment direction is parallel to the axial direction of the guide rod 32. This allows for adjustment of the maximum travel of the fan-shaped sealing plate 31, improving not only the sealing effect and reliability but also making the sealing mechanism 3 suitable for the sealing requirements of different specifications of drums 2. The aforementioned first limiting part 322 includes, but is not limited to, an adjusting nut screwed onto the guide rod 32. By tightening this adjusting nut, the position of the first limiting part 322 on the guide rod 32 can be adjusted.

[0043] In one embodiment, the initial compression of the compression spring 33 is adjustable. In this embodiment, the initial compression is defined as the compression of the compression spring 33 when the fan-shaped sealing plate 31 abuts against the large-diameter end / straight section 22 of the conical winding section 21. Based on the above design, the sealing effect and sealing reliability can be improved, ensuring that the fan-shaped sealing plate 31 can always press against the drum 2, and avoiding problems such as a decrease in sealing effect due to long-term operation of the device.

[0044] Accordingly, a spring adjustment part 34 is provided. In the scheme where the compression spring 33 is housed in the guide hole 112, the compression amount of the compression spring 33 can be adjusted by adding or removing shims within the large-diameter hole section; or, a clamping bolt is screwed onto the annular sealing seat 11. This clamping bolt is a hollow bolt that allows the guide rod 32 to pass through, and the end of the compression spring 33 abuts against the clamping bolt. By tightening the clamping bolt, the compression amount of the compression spring 33 can be adjusted.

[0045] In one embodiment, the guide rod 32 is a hollow shaft and is connected to an air-blowing unit for blowing air into its hollow cavity. A corresponding air-blowing channel is also formed on the fan-shaped sealing plate 31; for example, the shaft cavity of the aforementioned guide bushing 312 can form such a channel. Based on this design, compressed air is blown into the guide rod 32 by the air-blowing unit. This compressed air can enter between the sealing ring 30 and the drum 2, creating a dual sealing effect of mechanical and gas seals. This effectively prevents debris and other impurities from entering the annular gap between the drum 2 and the frame 1.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
