[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] As shown in Figures 1 and 2, an embodiment of the present invention provides a trimming material winding device, including a frame 1 and a reel 2. The reel 2 is equipped with a rotation drive unit for driving it to rotate around its own axis and a translation drive unit for driving it to move axially, which can realize the winding and unwinding of waste edges.

[0026] In one embodiment, the reel 2 travels on the transmission side frame 1 .

[0027] Preferably, as shown in Figures 1 and 2, the reel 2 includes a tapered winding section 21, the cross-sectional area of ​​which gradually increases as the reel 2 moves offline. This structure improves the winding of scrap edges and facilitates unloading. Furthermore, as shown in Figures 1 and 2, the reel 2 also includes a straight section 22 connected to the large-diameter end of the tapered winding section 21, through which the rotary drive unit and the translational drive unit can be connected.

[0028] Preferably, the reel 2 is provided with a sealing mechanism 3 at the passing position on the frame 1, and the sealing mechanism 3 is mainly used to seal the annular gap formed between the reel 2 and the frame 1, so as to prevent the waste edge head, tail, debris, etc. from entering the annular gap and causing jamming and thus affecting normal production, thereby effectively improving the working stability and reliability of the trimming material winding device.

[0029] Furthermore, the sealing mechanism 3 is a telescopic sealing mechanism 3 that can adapt to the cross-sectional changes of the reel 2. This structure is particularly suitable for the case where the reel 2 includes a conical winding section 21. Since the distance between the conical winding section 21 and the through hole gradually increases during the process of moving out of the frame 1, that is, the annular gap gradually increases, based on the above-mentioned telescopic sealing mechanism 3, it can adapt to the cross-sectional changes of the conical winding section 21 to ensure the continuity of the seal, and therefore has very high sealing reliability.

[0030] In one embodiment, as shown in Figures 3 and 4 , the sealing mechanism 3 comprises a plurality of sector-shaped sealing plates 31 that combine to form a sealing ring 30, and an expansion and contraction unit for adaptively expanding and contracting the sealing ring 30. Each sealing plate junction is provided with a movable sealing structure. The adaptive expansion and contraction of the sealing ring 30 achieves the aforementioned adaptive effect of the cross-sectional changes of the reel 2. The movable sealing structure at the junction of the sealing plates ensures consistent sealing during the expansion and contraction of the sealing ring 30, thereby achieving highly reliable sealing.

[0031] In one embodiment, as shown in Figure 4 , each end of the sector-shaped sealing plate 31 is provided with a tongue-and-groove portion 313. Each adjacent sector-shaped sealing plate 31 is connected by tongue-and-groove to form the movable sealing structure. Specifically, the tongue-and-groove portions 313 at each end of the sector-shaped sealing plate 31 are defined as a first tongue-and-groove portion and a second tongue-and-groove portion, respectively. The first tongue-and-groove portion of one sector-shaped sealing plate 31 is connected by tongue-and-groove to the second tongue-and-groove portion of the other sector-shaped sealing plate 31. During the expansion and contraction of the sealing ring 30, the two connected tongue-and-groove portions 313 move relative to each other, achieving a movable sealing effect.

[0032] Among them, the length of the tongue and groove portion 313 should meet the circumference change requirement of the sealing ring 30 during the expansion and contraction process. For example, the length of the tongue and groove portion 313 is defined as L, the number of fan-shaped sealing plates 31 is n, and nL should not be less than the maximum circumference change of the sealing ring 30 during the expansion and contraction process.

[0033] Preferably, as shown in FIG4 , the tongue-and-groove grooves at both ends of the sector-shaped sealing plate 31 face opposite directions. Based on this design, each sector-shaped sealing plate 31 can adopt the same structure, facilitating standardized production.

[0034] In another embodiment, the movable sealing structure may also adopt a retractable component such as a corrugated plate, and two adjacent sector-shaped sealing plates 31 may be connected by the retractable component, which can also meet the requirements of sealing continuity and reliability.

[0035] In one embodiment, as shown in Figures 3 and 4, the expansion and contraction unit includes multiple groups of damping structures, the damping structures are the same in number as the fan-shaped sealing plates 31 and are configured in a one-to-one correspondence, wherein the damping structure is installed on the frame 1, and the fan-shaped sealing plates 31 are connected to the corresponding damping structures.

[0036] As one of the embodiments, as shown in Figures 3 and 4, the damping structure includes a compression spring 33, and the fan-shaped sealing plate 31 is connected to a guide rod 32. The guide rod 32 is movably arranged on the frame 1, and the compression spring 33 is sleeved on the guide rod 32. One end of the compression spring 33 presses against the spring action surface on the fan-shaped sealing plate 31 / guide rod 32, and the other end presses against the spring action surface on the frame 1. The force of the compression spring 33 presses the fan-shaped sealing plate 31 tightly against the reel 2.

[0037] In one embodiment, as shown in Figures 3 and 4, the sector-shaped sealing plate 31 includes a guide sleeve 312 and two plate segments 311. The two plate segments 311 are relatively connected to two sides of the guide sleeve 312, and the guide sleeve 312 is connected to the guide rod 32.

[0038] Among them, preferably, the guide sleeve 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 sleeve 312 by threads, and can be locked and prevented from loosening by the end nut 321 and the gasket.

[0039] An annular baffle can be coaxially disposed within the guide sleeve 312, with the inner ring of the annular baffle having 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 disposed in the middle of the guide sleeve 312, forming axial cavities on both sides thereof. The end nut 321 is located in one of the axial cavities, and the compression spring 33 can extend into the other axial cavity to abut against the annular baffle. This arrangement can further improve the smooth movement of the sector-shaped sealing plate 31.

[0040] Preferably, as shown in FIG1 , FIG2 , FIG5 and FIG6 , an annular sealing seat 11 is provided on the frame 1 , and the sealing mechanism 3 is mounted on the annular sealing seat 11 .

[0041] As shown in Figures 5 and 6, a plurality of movable grooves 111 are correspondingly provided on the annular sealing seat 11 to accommodate each sector sealing plate 31 respectively, and the groove depth meets the movement requirements of the sector sealing plate 31. The guide rod 32 is arranged on the annular sealing seat 11 and can move relative to the annular sealing seat 11, thereby driving the sector sealing plate 31 to move within the movable groove 111; wherein, the movable groove 111 can be adapted to the guide sleeve 312, thereby guiding the movement of the guide sleeve 312, that is, improving the stability of the movement of the sector sealing plate 31; in addition, a guide hole 112 is further provided at the bottom of the movable groove 111 for the guide rod 32 to pass through and to accommodate the compression spring 33. Accordingly, the guide hole 112 is preferably a stepped hole, the diameter of the large diameter hole section of which is adapted to the diameter of the compression spring 33, and the diameter of the small diameter hole section of which is adapted to the diameter of the guide rod 32, and the other end of the compression spring 33 abuts against the stepped surface of the stepped hole.

[0042] In one embodiment, as shown in Figures 1-4, a first limiting portion 322 is provided at the end of the guide rod 32 away from the sector-shaped sealing plate 31, and a second limiting portion suitable for cooperating with the first limiting portion 322 is provided on the frame 1. In the scheme where the guide rod 32 passes through the annular sealing seat 11, the first limiting portion 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 constitute the above-mentioned second limiting portion. Based on the above structure, on the one hand, the maximum movable stroke of the sector-shaped sealing plate 31 can be limited, and on the other hand, the guide rod 32 and the sector-shaped sealing plate 31 can be prevented from detaching from the frame 1, thereby ensuring sealing reliability and equipment safety.

[0043] Further preferably, the position of the first limiting portion 322 on the guide rod 32 is adjustable, and the position adjustment direction is parallel to the axial direction of the guide rod 32, and / or the position of the second limiting portion on the frame 1 is adjustable, and the position adjustment direction is parallel to the axial direction of the guide rod 32. Thus, the maximum movable stroke of the sector-shaped sealing plate 31 can be adjusted, which not only improves the sealing effect and sealing reliability, but also enables the sealing mechanism 3 to be adapted to the sealing requirements of reels 2 of different specifications. The first limiting portion 322 includes, but is not limited to, an adjusting nut threaded onto the guide rod 32. By screwing the adjusting nut, the position of the first limiting portion 322 on the guide rod 32 can be adjusted.

[0044] In one embodiment, the initial compression amount of the compression spring 33 is adjustable; in this embodiment, the initial compression amount is defined as the compression amount of the compression spring 33 when the fan-shaped sealing plate 31 abuts against the large diameter end / straight tube 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 be tightly pressed against the reel 2, and avoiding problems such as a decrease in sealing effect due to long-term operation of the device.

[0045] Accordingly, a spring adjustment portion 34 is provided. In the scheme where the compression spring 33 is accommodated in the guide hole 112, the compression amount of the compression spring 33 can be adjusted by adding or removing gaskets in the large-diameter hole section; alternatively, a compression bolt is screwed onto the annular sealing seat 11. The compression bolt is hollow to allow the guide rod 32 to pass through, and the end of the compression spring 33 abuts against the compression bolt. By tightening the compression bolt, the compression amount of the compression spring 33 can be adjusted.

[0046] In one embodiment, the guide rod 32 is a hollow shaft connected to a blowing unit for blowing air into its hollow cavity. A blowing channel is also formed on the fan-shaped sealing plate 31. For example, the axial cavity of the guide sleeve 312 can form this blowing channel. Based on this solution, compressed air is blown into the guide rod 32 through the blowing unit. The compressed air can enter between the sealing ring 30 and the reel 2, forming a dual sealing effect of mechanical and gas sealing, which can effectively prevent debris and other foreign matter from entering the annular gap between the reel 2 and the frame 1.

[0047] 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 in the scope of protection of the present invention.
