[0022] like Figure 1-6 As shown, this utility model provides an auxiliary blocking structure for a winding device, including a baffle structure, a core 1, and a roll 2.

[0023] As one embodiment of this utility model, the first fixing seat 5 and the second fixing seat 6 are semi-circular arc-shaped, and the first fixing seat 5 and the second fixing seat 6 are snapped onto the outside of the core 1 after being combined.
[0024] In another embodiment of this utility model, the lengths of the first baffle 3 and the second baffle 4 are both greater than the radius of the roll 2.
[0025] In another embodiment of this utility model, the first baffle 3 and the second baffle 4 are fan-shaped.
[0026] In another embodiment of this utility model, the connecting structure includes a hinge 8, a hinge seat 7, and a plurality of fixing bolts 9. The hinge 8 is disposed at the top center of the hinge seat 7. One bottom end of the hinge seat 7 is connected to one end of the first fixing seat 5 by the fixing bolts 9, and the other bottom end of the hinge seat 7 is connected to one end of the second fixing seat 6 by the fixing bolts 9.
[0027] In another embodiment of the present invention, the connecting structure further includes a first anti-loosening plate 10, a second anti-loosening plate 11, and an anti-loosening washer 12. The first anti-loosening plate 10 is connected to the top of one end of the hinge seat 7, the second anti-loosening plate 11 is connected to the top of the other end of the hinge seat 7, the first anti-loosening plate 10 and the second anti-loosening plate 11 are pressed against the top of the fixing bolt 9, and the anti-loosening washer 12 abuts against the adjacent fixing bolts 9.
[0028] In another embodiment of this utility model, an adjustment structure is also included. The adjustment structure includes an adjustment rod 13, a first adjustment seat 14, a second adjustment seat 15, a first connecting rod 17, and a second connecting rod 18. The adjustment rod 13 is disposed on the first adjustment seat 14, the first adjustment seat 14 is disposed on the first fixed seat 5, the second adjustment seat 15 is disposed on the second fixed seat 6, one end of the first connecting rod 17 is connected to the second adjustment seat 15, and the other end of the first connecting rod 17 is connected to the adjustment rod 13. One end of the second connecting rod 18 is connected to the second adjustment seat 15, and the other end of the second connecting rod 18 is connected to the adjustment rod 13.
[0029] In another embodiment of the present invention, the first adjusting seat 14 is provided with a self-locking buckle 16, which is fastened to the adjusting rod 13.
[0030] In another embodiment of this utility model, the gap between the baffle structure and the roll material 2 is 4-6 mm.
[0031] This utility model provides an auxiliary blocking structure for a winding device. By setting baffle structures on both sides of the roll 2, the winding and unwinding range of the roll 2 is limited by the baffles, reducing the occurrence of slippage, making the roll 2 more regular after winding, eliminating the need for rewinding, and improving work efficiency.
[0032] During installation, the first fixing seat 5 and the second fixing seat 6 are secured to the winding core 1, and the first fixing seat 5 and the second fixing seat 6 are connected using the connecting structure. For example... Figure 1As shown, the first baffle 3 and the second baffle 4 extend out of the roll 2. During winding, the film material that slides out will be blocked by the first baffle 3 and the second baffle 4 and return to the roll 2. When deviation occurs, it can be corrected to ensure that the winding end face is flat, thereby meeting customer specifications and achieving the standard for shipment.
[0033] The first baffle 3 and the second baffle 4 are preferably fan-shaped, as this maximizes the contact surface for correction. When the first baffle 3 and the second baffle 4 rotate with the core 1, they form a circular correction surface, improving the correction effect. Simultaneously, the distance between the first baffle 3 and the second baffle 4 and the roll 2 is 4-6mm to prevent the core 1 from being jammed due to excessive distance.
[0034] One end of the first fixing seat 5 is connected to one end of the second fixing seat 6 via the connecting structure. The hinge seat is connected to both the first fixing seat 5 and the second fixing seat 6. The hinge 8 is used to open and close the first baffle 3 and the second baffle 4. The fixing bolt 9 is used to fix the hinge seat. The first anti-loosening plate and the second anti-loosening plate prevent the fixing bolt 9 from falling off. The anti-loosening washer 12 prevents the first anti-loosening plate and the second anti-loosening plate from falling off. Through the performance of the hinge 8, the first fixing seat 5 can rotate at a certain angle relative to the second fixing seat 6 to accommodate the core 1 of different diameters.
[0035] When using the first baffle 3 and the second baffle 4, they need to be flexibly disassembled and used. The second adjusting seat 15 is set on the second fixed seat 6. There is a groove on the second adjusting seat 15. The first connecting rod 17 and the second connecting rod 18 can be locked in the groove. When the adjusting rod 13 is pulled up, due to the lever principle, the first connecting rod 17 and the second connecting rod 18 can be disengaged from the groove of the second adjusting seat 15. Then, through the opening and closing action of the hinge 8, free disassembly can be achieved. The adjusting rod 13 can be freely adjusted to meet the use of the core 1 of different diameters. When the self-locking buckle 16 is pulled down, it can lock the pivot of the adjusting rod 13, so that the adjusting rod 13 cannot rotate and achieves self-locking. When the self-locking buckle 16 is pulled up, it can release the self-locking state. The self-locking buckle 16 can prevent the entire component from popping up and falling off during use.
[0036] By designing a novel winding auxiliary baffle, the problem of material slippage during winding is overcome. Operation is simple, requiring no prior experience, and effectively corrects slippage during winding. It is low-cost and fast-acting, and the use of self-locking buckles and anti-loosening screws for reinforcement eliminates the risk of leakage. Before implementation, 429 rolls were produced, with 93 experiencing slippage (21% defect rate); after implementation, 467 rolls were produced, with only 16 experiencing slippage (3% defect rate), representing an 18% year-on-year decrease. This reduces cost losses, improves product utilization, increases uptime, and ultimately increases company profits.
[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
