Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mattress packaging, and in particular to a device for conveying film and a wrapping machine. Background Art
[0002] The existing mattress rolling machine combines the rolling process and the bundling process. When the rolling is about to be completed, the film is sent to the mattress roll by the device for conveying the film so that the film is rolled together with the mattress, and the mattress is bundled by the film's own viscosity. Since the plastic film itself is light in weight, has a certain viscosity and is prone to static electricity, it is very easy to be adsorbed to the surrounding structure during the conveying process, resulting in the film not being effectively conveyed to the mattress and rolled together with the mattress.

[0032] refer to Figure 1 The present application provides a device for conveying a film, including a conveying mechanism 1 and a guide member 2; the conveying mechanism 1 is used to convey a film 100, including a first roller 11 and a second roller 12; the second roller 12 is arranged on one side of the first roller 11, and a conveying space is formed between the second roller 12 and the first roller 11, and the first roller 11 and the second roller 12 both rotate along the conveying direction of the film 100 to jointly clamp the conveyed film 100; the guide member 2 is used to guide the film 100 along the conveying direction, and the surface of the guide member 2 in contact with the film 100 has an antistatic material to prevent or reduce static electricity between the guide member 2 and the film 100.
[0033] The guide member 2 may also be provided with a moisturizing layer, which may be located between the guide member 2 and the conveying mechanism 1, or as an internal interlayer of the guide member 2, to provide moisture to the guide member 2 to prevent the surface of the guide member 2 from being too dry, thereby reducing the accumulation of static electricity and reducing the generation of static electricity.
[0034] According to one embodiment of the present application, the moisturizing layer may include moisturizing materials such as hydrogel. The antistatic material includes antistatic nylon, natural fiber, etc. The natural fiber may include at least one of cotton, wool, silk and linen. The surface of the guide member 2 may also be coated with an antistatic coating to replace the antistatic material.
[0035] The film 100 is conveyed and guided by the conveying mechanism 1 and the guide member 2. One end of the film 100 in the film roll 200 is placed in the conveying space, and the film 100 is brought into contact with the first roller 11 and the second roller 12 on both sides of the conveying space, so that the film 100 is clamped between the first roller 11 and the second roller 12. The first roller 11 and the second roller 12 are both rotated in the conveying direction, thereby driving the film 100 to move and feed in the conveying direction. The good antistatic property of the antistatic material on the surface of the guide member 2 can reduce the static electricity generated during the conveying process of the film 100.
[0036] like Figure 1 As shown, as an optional embodiment, the guide member 2 is a transmission belt, which is arranged at at least one of the first roller 11 and the second roller 12, and transmits along the conveying direction.
[0037] In some embodiments, the transmission belt may also be disposed at the output end of the first roller 11 or the second roller 12 .
[0038] The film 100 is guided and conveyed by the transmission belt, so that the transmission effect of the film 100 is further improved.
[0039] like Figure 4 As shown, as an optional implementation, the guide member 2 is a guide plate; wherein the guide plate is arranged at the output end of the first roller 11 or the second roller 12, and is used to guide and limit the film 100, thereby improving the reliability of feeding.
[0040] like Figure 1 and Figure 2 As shown, as an optional embodiment, the guide member 2 is provided with a hollow portion 22, and the hollow portion 22 is provided on the surface of the guide member 2 to reduce the contact area between the guide member 2 and the film 100, thereby reducing the adsorption phenomenon between the film 100 and the surface of the guide member 2.
[0041] As an optional implementation, the guide member 2 is further provided with an air supply component 21 , and the air supply component 21 supplies air to the film 100 through the hollow portion 22 to prevent the film 100 from being adsorbed on the guide member 2 .
[0042] As an optional embodiment, the air supply component 21 includes a compressed air pipe or a fan.
[0043] During the transmission process of the guide member 2, the air delivery component 21 delivers air to the film 100 through the hollow portion 22. For example, when the guide member 2 is a conveyor belt, the air delivery component 21 can be arranged inside the guide member 2. When the guide member 2 is a guide plate, the air delivery component 21 can be arranged on the side of the guide member 2 opposite to the film 100. The generated airflow prevents the film 100 from directly contacting the guide member 2, thereby generating isolation and preventing the film 100 from being adsorbed on the guide member 2 and causing feeding failure.
[0044] In some embodiments, the gas may be directly applied to the film 100 only through the gas delivery component 21. Figure 3 As shown, a plurality of mutually interrupted or spaced guide members 2 are arranged along the conveying direction, and an air supply component 21 can be provided at the intervals between two adjacent guide members 2. The air supply components 21 at the intervals between the guide members 2 directly apply gas to the film 100 to prevent the film 100 from being adsorbed.
[0045] like Figure 4 As shown, as an optional embodiment, the device for conveying the film further includes a static eliminator 4, which is arranged at a distance from the guide member 2 on the side of the film 100 to further eliminate static electricity of the film.
[0046] In some embodiments, the static eliminator 4 and the ion air gun or electrode rod are selected.
[0047] like Figure 1 As shown, as an optional embodiment, the conveying mechanism 1 includes a telescopic component 13, which is connected to at least one of the first roller 11 and the second roller 12, and is used to make the first roller 11 and the second roller 12 move closer to or farther away from each other to change the size of the conveying space.
[0048] As an optional embodiment, the conveying mechanism 1 includes an antistatic layer, which is disposed on the surface of the first roller 11 and / or the second roller 12 in contact with the film 100 to prevent or reduce static electricity between the surface of the conveying mechanism 1 and the film 100 .
[0049] The antistatic layer can be made of antistatic nylon or natural fiber.
[0050] As an optional embodiment, the device for conveying film provided in the present application further includes a cutting device 3, which is arranged at the output end of the conveying mechanism 1 and is used to cut the film 100 to complete the wrapping of the film 100 and the wrapped object such as the mattress.
[0051] According to one embodiment of the present application, the cutting device 3 can be a cutter.
[0052] The present application also provides a wrapping machine, comprising the above-mentioned device for conveying film.
[0053] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. At the same time, changes or deformations made by those skilled in the art based on the ideas of the present application, the specific implementation methods and the scope of application of the present application, all belong to the scope of protection of the present application.
