Description

Technical Field

[0001] This utility model relates to the field of film winding device technology, and more specifically, to an auxiliary anti-slip device for winding core. Background Technology

[0002] Currently, the auxiliary edge-trimming machines used in the market all use air-expansion shafts to clamp the cores at both ends, making the cores easy to remove and replace. The surface of the cores used for wrapping waste film is smooth, and the waste film is prone to slipping on the surface of the cores when wrapping. Slipping can occur if the winding time is long, causing the production line to stop. Improper operation when wrapping waste film with the cores can cause personnel to be drawn into the cores, resulting in winding injuries. Utility Model Content

[0007] This utility model provides an auxiliary anti-slip device for winding cores, including a core, a first clamping half tube, and a second clamping half tube; the first clamping half tube and the second clamping half tube are detachably connected and clamped and fixed to the outer periphery of the core; wherein, two anti-slip blocks are arranged radially on the outer periphery of the first clamping half tube and / or the second clamping half tube, and the two anti-slip blocks are spaced apart to form a winding space for winding waste film.

[0008] Preferably, it further includes fasteners, through which the first clamping half-tube and the second clamping half-tube are fastened together.

The first connecting plate is fixedly connected to the outer periphery of one end of the first half-tube, and the second connecting plate is fixedly connected to the outer periphery of the other end of the first half-tube.

[0010] Preferably, the second clamping half-tube includes a second half-tube, a third connecting plate, and a fourth connecting plate. The third connecting plate is fixedly connected to the outer periphery of one end of the second half-tube, and the fourth connecting plate is fixedly connected to the outer periphery of the other end of the second half-tube. The fastener securely connects the first connecting plate and the third connecting plate, and the fastener securely connects the second connecting plate and the fourth connecting plate.

[0017] (III) Beneficial Effects

[0018] The above-mentioned technical solution of this utility model has at least the following advantages:

[0019] In this invention, waste film is wound within a first winding space. Anti-slip blocks restrict the movement of both ends of the waste film along the length of the core, thus preventing slippage. As time increases, the thickness of the waste film stacked in the first winding space increases. When the winding thickness of the waste film exceeds the height of the anti-slip blocks along the radial direction of the core, the waste film automatically unwinds. Because the waste film wound in the first winding space has a certain thickness, subsequent windings will form a winding state that is high in the middle and low on both sides. That is, subsequent windings will be in a stretched state. Under the generated tension, the waste films can adhere more tightly, increasing the friction coefficient between adjacent waste films, thereby preventing slippage of subsequent windings.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0030] like Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides an auxiliary winding core anti-slip device, including a core 1, a first clamping half tube 2, and a second clamping half tube 3; the first clamping half tube 2 and the second clamping half tube 3 are detachably connected and clamped and fixed on the outer periphery of the core 1; wherein, two anti-slip blocks 4 are arranged radially on the outer periphery of the first clamping half tube 2 and / or the second clamping half tube 3, and the two anti-slip blocks 4 are spaced apart to form a first winding space 5 for winding waste film.

[0031] As one optional implementation of this embodiment, a fastener (not shown) is also included, and the first clamping half-tube 2 and the second clamping half-tube 3 are fastened together by the fastener. Specifically, the fastener includes, but is not limited to, bolts, screws, etc.

[0032] In one optional implementation of this embodiment, the first clamping half-tube 2 includes a first half-tube 21, a first connecting plate 22, and a second connecting plate 23. The first connecting plate 22 is fixedly connected to the outer periphery of one end of the first half-tube 21, and the second connecting plate 23 is fixedly connected to the outer periphery of the other end of the first half-tube 21. Specifically, the inner diameter of the first half-tube 21 matches the outer radial diameter of the core 1, that is, the inner diameter of the first half-tube 21 is the same as the outer diameter of the core 1.

[0033] In one optional embodiment of this invention, the second clamping half-tube 3 includes a second half-tube 31, a third connecting plate 32, and a fourth connecting plate 33. The third connecting plate 32 is fixedly connected to the outer periphery of one end of the second half-tube 31, and the fourth connecting plate 33 is fixedly connected to the outer periphery of the other end of the second half-tube 31. Fasteners securely connect the first connecting plate 22 and the third connecting plate 23, and fasteners also securely connect the second connecting plate 32 and the fourth connecting plate 33. Specifically, the inner diameter of the second half-tube 31 matches the outer radial diameter of the core 1, that is, the inner diameter of the second half-tube 31 is the same as the outer diameter of the core 1.

[0034] As one optional implementation of this embodiment, the first connecting plate 22 and the third connecting plate 23 are provided with a second winding space 6 for winding waste film. The first connecting plate 22 and the third connecting plate 23 are configured as separate structures, and the second winding space 6 is provided on them for winding waste film. At this time, the first connecting plate 22 and the third connecting plate 23 can also play the same role as the anti-slip block 4, that is, to restrict the two ends of the waste film from sliding along the length direction of the core 1.

[0035] In one optional embodiment of this invention, the second connecting plate 32 and the fourth connecting plate 33 are provided with a third winding space 7 for winding waste film. The second connecting plate 32 and the fourth connecting plate 33 are configured as separate structures, and the third winding space 7 is provided on them for winding waste film. In this case, the second connecting plate 32 and the fourth connecting plate 33 can also play the same role as the anti-slip block 4, that is, to restrict the two ends of the waste film from sliding along the length direction of the core 1.

[0036] In one optional embodiment of this invention, the inner wall of the first clamping half-tube 2 that contacts the winding core 1 is provided with an anti-slip layer (not shown). Specifically, the anti-slip layer is a polished surface layer or a material with a relatively rough surface, such as rubber. This increases the surface friction coefficient of the contact surface, thereby preventing slippage between the first clamping half-tube 2 and the winding core 1.

[0037] In one optional embodiment of this invention, the inner wall of the second clamping half-tube 3 that contacts the core 1 is provided with an anti-slip layer (not shown). Specifically, the anti-slip layer is a polished surface layer or a material with a relatively rough surface, such as rubber. This increases the surface friction coefficient of the contact surface, thereby preventing slippage between the second clamping half-tube 3 and the core 1.

[0038] As one optional implementation of this embodiment, a gasket (not shown) is also included. The gasket is disposed between the first clamping half-tube 2 and the core 1, and / or the gasket is disposed between the second clamping half-tube 3 and the core 1. During installation, if slippage is still found between the first clamping half-tube 2 / second clamping half-tube 3 and the core 1, a gasket can be added between them. Under the tightening force generated by the fasteners, the first clamping half-tube 2 / second clamping half-tube 3, the gasket, and the core 1 will fit more tightly, thereby preventing slippage.

[0039] As one optional implementation of this embodiment, the height of the anti-slip block 4 is 25mm, and the width of the first winding space 5 is 100mm. The specific dimensions can be determined according to actual usage requirements.

[0040] Specifically, please combine Figure 1 , Figure 2 as well as Figure 3 The specific implementation principle of the embodiment shown is as follows:

[0041] In practical use, the auxiliary winding core anti-slip device provided in this embodiment is connected to the corresponding drive assembly. For example, the core 1 is connected to the output end of the drive motor, which can drive the core 1 to rotate, thereby realizing the winding of waste film. First, the first clamping half tube 2 and the second clamping half tube 3 are fastened to the outer periphery of the middle part of the core 1 with fasteners (such as bolts). Then, the waste film is fixed to the surface of the first clamping half tube 2 or the second clamping half tube 3, so that the two ends of the width of the waste film abut against the two anti-slip blocks 4 respectively, so as to ensure that the waste film is within the first winding space 5. The anti-slip blocks 4 can restrict the movement of the two ends of the waste film along the length direction of the core 1, thereby preventing the waste film from slipping in the length direction of the core 1. Then, the corresponding drive component is activated, which drives the core 1 to rotate, thereby winding the waste film into the first winding space 5. As time increases, the thickness of the waste film stacked in the first winding space 5 becomes thicker and thicker. When the winding thickness of the waste film is higher than the height of the anti-slip block 4 along the radial direction of the core, the waste film will automatically unfold (the normal unfolded width of the waste film is greater than the width between the two anti-slip blocks). At this time, since the waste film wound in the first winding space 5 has a certain thickness, the waste film wound later will form a winding state with a high middle and low sides, that is, the waste film wound later will be in a stretched state, which makes the waste film fit more tightly with each other, increases the friction coefficient between adjacent waste films, and thus prevents the waste film wound later from slipping.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
