By arranging mesh holes distributed at intervals on a packing film body and bonding an air-conducting sealing sticker corresponding to the position of the mesh holes to one end face of the packing film body, after the cotton roll is packed, a plurality of elastic ropes at the side ends of the air-conducting sealing sticker are cross-arranged on the side ends of the cotton roll to elastically press the side ends of the cotton roll, so that the cotton is not easily loosened and dropped at the side ends of the cotton roll, and the moisture inside the cotton roll can pass through the mesh holes to form visible water droplets on the inner wall of the air-conducting sealing sticker, so that personnel can visually judge the moisture condition of the cotton roll from the outside. When necessary, personnel can use the air-conducting sealing sticker to perform an operation process of first evacuating air and then filling hot air inside the cotton roll, so that the inside of the cotton roll can continuously exchange gas flow with the outside, thereby realizing a double-pass dehumidification and drying process inside the cotton roll, and effectively improving the storage quality and duration of the cotton roll.

Description

Technical Field

[0001] The invention relates to a cotton packaging film, in particular to a cotton packaging film with side sealing and dehumidification functions applied in the field of material packaging. Background Art

[0002] Baling film is one of the commonly used baling materials in agricultural harvesting operations. It is soft and can be used for large quantities at a time, so it is suitable for on-site packaging of cash crops such as cotton. After the cotton is packed into rolls, the baling film is adhered by glue to form a firm and stable cotton bale, which is convenient for handling and transportation.

[0003] Because the packaging film is generally used to package the cotton on site, the packaged cotton has not been processed yet and often contains a certain amount of moisture. In addition, during transportation and storage, cotton easily absorbs more moisture in the air, resulting in the cotton bale often containing more moisture that is difficult to dissipate, thus affecting the storage quality of the cotton and making it prone to moisture and deterioration.

[0004] The specification of Chinese patent CN202110295282.2 discloses a method for packing cotton with intertwining and moisture-proof packaging film based on packaging film, in which the cotton is packed into a rolled cylinder with a dehumidifying packaging film, so that the cotton contacts the moisture-absorbing balls on the back of the single-sided moisture-absorbing film in layers in a spiral manner, and the moisture-absorbing balls penetrate into the interior of the cotton to achieve uniform dehumidification of the interior of the cotton. In addition, the absorbed moisture of the cotton is introduced into the interior of the single-sided moisture-absorbing film to prevent it from flowing back into the interior of the cotton. The moisture is dissipated and removed through convection between the interior of the single-sided moisture-absorbing film and the outside air, thereby effectively ensuring that the cotton is not easily affected by moisture and deterioration during storage, thereby increasing the storage period of the cotton.

[0005] In the above-mentioned prior art, when using packaging film to pack cotton, although a hygroscopic structure is provided to absorb moisture inside the cotton, the hygroscopic structure after absorbing moisture is still in contact with the cotton and releases moisture relatively slowly, so the dehumidification effect on the cotton is poor. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the prior art uses a packaging film to pack cotton, although a hygroscopic structure is provided to absorb moisture inside the cotton, the hygroscopic structure after absorbing moisture is still in contact with the cotton, and its release of moisture is relatively slow, so the dehumidification effect on the cotton is poor.

[0007] In order to solve the above problems, the present invention provides a cotton packaging film with side sealing and dehumidification functions, including a packaging film body, one end face of the packaging film body is bonded with a plurality of evenly distributed air-conducting sealing stickers, the air-conducting sealing stickers include an inner flexible frame bonded to the packaging film body, the end of the inner flexible frame away from the packaging film body is fixedly connected with an outer flexible frame, the inner end of the outer flexible frame is fixedly connected with an elastic membrane, the elastic membrane is made of transparent elastic material, the outer end of the elastic membrane is fixedly connected with an air pipe joint, and the air pipe joint penetrates the elastic membrane and communicates with the inner side of the inner flexible frame, a pair of side ends of the inner flexible frame are fixedly connected with a plurality of elastic ropes, a plurality of mesh holes are opened on the packaging film body, the plurality of mesh holes are respectively located on the inner sides of the plurality of inner flexible frames, and the mesh holes are composed of a plurality of evenly distributed air holes.

[0008] As a further supplement to the present application, the lengths of the multiple elastic ropes are the same, and when the inner flexible frame is in a horizontal normal straight state, the elastic ropes are in a horizontal stretched state.

[0009] As a further supplement to the present application, the width of the inner flexible frame is the same as the width of the packaging film body, the length of the inner flexible frame is smaller than the circumference of the cotton roll to be packaged, and the initial length of the elastic rope is smaller than the diameter of the cotton roll to be packaged.

[0010] A cotton packaging film with side sealing and dehumidification functions, and a method for packaging cotton comprising the following steps:

[0011] S1: After the cotton is processed and rolled into a cylindrical cotton roll, the cotton roll is placed on an end surface of the packaging film body that does not include an inner flexible frame;

[0012] S2, controlling the rotation of the cotton roll so that the end of the packaging film body that does not contain the inner flexible frame faces the cotton roll for wrapping;

[0013] S3, when the packaging film body completely wraps the cotton roll, the packaging film body portion between two adjacent outer flexible frames is cut off by a cutting tool, and then the head and tail ends of the packaging film body at the outer end of the cotton roll are bonded and fixed;

[0014] After the packaging film body wraps the cotton roll, the inner flexible frame and the outer flexible frame are wrapped around the outside of the cotton roll through the packaging film body, and the arc-shaped inner flexible frame drives multiple elastic ropes to be arranged at the side ends of the cotton roll in a cross shape, thereby playing a side sealing role for the cotton roll.

[0015] A cotton packaging film with side sealing and dehumidification functions, wherein the dehumidification process of the cotton roll comprises the following steps:

[0016] W1. When water droplets are observed condensing on the inner surface of the elastic film from the outside, it indicates that there is a lot of moisture in the cotton roll;

[0017] W2. Connect the trachea joint to the external air pump, start the air pump, and let it suck air into the inner side of the elastic membrane through the trachea joint. Under the action of negative pressure, the outside gas can enter the inside through the side end of the cotton roll, driving the airflow and moisture inside the cotton roll. Finally, the gas carrying moisture overflows through the mesh to between the inner flexible frame and the outer flexible frame, and is sucked out by the air pump through the trachea joint, realizing the dehumidification process inside the cotton roll.

Connect the air pipe joint with the air outlet of the hot air blower, start the hot air blower to pass hot air into the air pipe joint, and the hot air enters between the inner flexible frame and the outer flexible frame, causing the elastic membrane to expand. At the same time, the hot air is released into the cotton roll through the mesh at a slow rate, driving the airflow and residual moisture inside the cotton roll, and finally releasing it from both ends of the cotton roll to the outside, thereby realizing a deep dehumidification process inside the cotton roll.

[0020] As another improvement of the present application, a plurality of strip films and a plurality of strip mesh belts are combined to replace the packaging film body with mesh holes, the plurality of strip films and the strip mesh belts are distributed at intervals, and each strip mesh belt is arranged between an adjacent pair of strip films.

When necessary, personnel can use the air-conducting sealing sticker to perform the operation process of first vacuuming and then filling the cotton roll with hot air, so that the inside of the cotton roll can continuously exchange gas and fluid with the outside world, thereby realizing a double-pass dehumidification and drying process inside the cotton roll, effectively improving the storage quality and duration of the cotton roll.

[0036] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0037] The first implementation method:

[0038] The present invention provides a cotton packaging film with side sealing and dehumidification functions, please refer to Figure 1 and Figure 2, including a packaging film body 1, one end surface of the packaging film body 1 is bonded with a plurality of evenly distributed air-conducting sealing stickers, the air-conducting sealing sticker includes an inner flexible frame 2 bonded with the packaging film body 1, an end of the inner flexible frame 2 away from the packaging film body 1 is fixedly connected with an outer flexible frame 3, the inner flexible frame 2 and the outer flexible frame 3 can both be made of flexible rubber material, the inner end of the outer flexible frame 3 is fixedly connected with an elastic film 4, the elastic film 4 is made of transparent elastic material, such as elastic plastic film, the inner flexible frame 2 plays a role in isolating the elastic film 4 and the mesh 101, so that the cotton The internal moisture can pass through the mesh 101 and condense into visible water droplets on the inner surface of the elastic film 4, which is convenient for visual judgment whether there is a lot of moisture inside the cotton. The outer end of the elastic membrane 4 is fixedly connected to the trachea connector 6, and the trachea connector 6 passes through the elastic membrane 4 and communicates with the inner side of the inner flexible frame 2. A pair of side ends of the inner flexible frame 2 are fixedly connected to multiple elastic ropes 5. A plurality of mesh holes 101 are opened on the packaging film body 1, and the plurality of mesh holes 101 are respectively located on the inner sides of the plurality of inner flexible frames 2, and the mesh holes 101 are composed of a plurality of evenly distributed air holes.

[0039] The lengths of the multiple elastic ropes 5 are the same. When the inner flexible frame 2 is in a horizontal normal straight state, the elastic ropes 5 are in a horizontal stretched state (Supplementary explanation: 1. Figure 3 In order to facilitate the clear drawing of the elastic rope 5, the elastic rope 5 is set in an arc state to assist those skilled in the art to understand that in actual situations the elastic rope 5 is in a stretched and taut linear state; Figure 3 , Figure 6-Figure 9 In the figure, solid lines and dotted lines with different transparencies are used to draw the multiple elastic ropes 5 respectively, which is also to assist technical personnel in the field to understand that in practice, the materials of the multiple elastic ropes 5 are exactly the same), the width of the inner flexible frame 2 is the same as the width of the packaging film body 1, the length of the inner flexible frame 2 is smaller than the circumference of the cotton roll to be packaged, and the initial length of the elastic rope 5 is smaller than the diameter of the cotton roll to be packaged.

[0040] According to the above-mentioned size setting, before packing cotton, the packing film body 1 with the inner flexible frame 2 and the elastic rope 5 of suitable size can be selected according to the diameter size of the cotton roll to be packed, so that after packing the cotton roll, the wrapping angle of the inner flexible frame 2 to the cotton roll is preferably between 270° and 300°, and multiple elastic ropes 5 in a stretched state can be cross-arranged at the outer end of the cotton roll to elastically suppress the side end of the cotton roll, so that the cotton is not easy to loosen and fall off at the side end of the cotton roll (such as Figure 6 and Figure 7 as shown).

[0041] A cotton packaging film with side sealing and dehumidification functions, and a method for packaging cotton comprising the following steps:

[0042] S1: Figure 4As shown, after the cotton is processed and rolled into a cylindrical cotton roll, the cotton roll is placed on an end surface of the packaging film body 1 that does not include the inner flexible frame 2;

[0043] S2, such as Figure 4 As shown, the cotton roll is controlled to rotate so that the end of the packaging film body 1 that does not contain the inner flexible frame 2 faces the cotton roll for wrapping;

[0044] S3, after the packaging film body 1 completely wraps the cotton roll, a cutting tool is used to cut off the packaging film body 1 between two adjacent outer flexible frames 3 ( Figure 5 The dotted line box indicates the cuttable area), and then the head and tail ends of the packaging film body 1 at the outer end of the cotton roll are bonded and fixed (such as Figure 6 shown);

[0045] After the packaging film body 1 wraps the cotton roll, the inner flexible frame 2 and the outer flexible frame 3 are wrapped around the outer side of the cotton roll through the packaging film body 1, and the arc-shaped inner flexible frame 2 drives multiple elastic ropes 5 to be arranged at the side ends of the cotton roll in a cross shape, which plays a side sealing role for the cotton roll (such as Figure 6 and Figure 7 as shown).

[0046] A cotton packaging film with side sealing and dehumidification functions, wherein the dehumidification process of the cotton roll comprises the following steps:

[0047] W1, such as Figure 8 As shown, when water droplets are condensed on the inner surface of the elastic film 4 from the outside visually, it indicates that there is more moisture in the cotton roll;

[0048] W2, such as Figure 8 As shown, the trachea connector 6 is connected to an external air pump, and the air pump is started to suck air into the inner side of the elastic membrane 4 through the trachea connector 6. Under the action of negative pressure, external air can enter the interior through the side end of the cotton roll, driving the airflow and moisture inside the cotton roll. Finally, the gas carrying moisture overflows through the mesh 101 to between the inner flexible frame 2 and the outer flexible frame 3, and is sucked out by the air pump through the trachea connector 6, thereby realizing the dehumidification process inside the cotton roll.

[0049] A cotton packaging film with side sealing and dehumidification functions, wherein the dehumidification process of the cotton roll further comprises the following steps after step W2:

[0050] W3, such as Fig. 9 As shown, the air pipe joint 6 is connected to the air outlet of the hot air blower, and the hot air blower is started to pass hot air into the interior of the air pipe joint 6. The hot air enters between the inner flexible frame 2 and the outer flexible frame 3, causing the elastic membrane 4 to expand. At the same time, the hot air is released into the cotton roll through the mesh 101 at a slow rate, driving the airflow and residual moisture inside the cotton roll, and finally releasing them from both ends of the cotton roll to the outside, thereby realizing a deep dehumidification process inside the cotton roll.

[0051] Second implementation method:

[0052] Based on the first embodiment, the present embodiment adopts a plurality of strip films 11 and a plurality of strip mesh belts 12 to replace the packaging film body 1 with mesh holes 101. Fig.10 and Fig.11 As shown, a plurality of strip films 11 and strip mesh belts 12 are distributed at intervals, and each strip mesh belt 12 is arranged between an adjacent pair of strip films 11, and the strip mesh belt 12 plays the same role as the mesh hole 101, that is, the gas can enter and exit the cotton roll through the strip mesh belt 12, thereby facilitating the dehumidification process of the cotton roll, and the adjacent strip films 11 and the strip mesh belts 12 are connected by bonding, and the strip films 11 are made of the same material as the packaging film body 1, and the strip films 11 can be cut from the complete packaging film body 1.

[0053] The main raw material for the production and processing of cotton packaging film comes from ethylene monomer obtained by petroleum cracking. Ethylene monomer undergoes polymerization reaction to generate polyethylene particles. Therefore, the production of cotton packaging film consumes a large amount of non-renewable resources such as petroleum. Compared with the process of making holes in the packaging film body 1 to prepare the mesh 101 in embodiment 1, the present embodiment adopts the method of cutting the packaging film body 1 to obtain the strip film 11, which can effectively avoid the generation of opening debris caused by the opening, thereby effectively reducing the waste of the packaging film body 1.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
