Description

Technical Field

[0001] This invention relates to a paper pad and its forming method. Background Technology

[0002] Some fragile items may break during transportation due to vibrations and bumps from the vehicle. Currently, fragile items are generally wrapped with paper pads to protect them from impacts and shocks.

[0003] Some fragile items have irregular shapes, and when wrapped with paper pads, the gaps in the packaging box cannot be filled, allowing the items to still move inside the box and posing a risk of breakage. This also consumes a lot of paper pads, resulting in higher costs. Alternatively, when wrapping small fragile items with paper pads, it is common to wrap them many times, which consumes a lot of paper pads and increases packaging costs.

[0004] Therefore, overcoming the aforementioned technical deficiencies is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a paper pad and its forming method.

[0006] According to one aspect of the invention, a paper pad is provided, comprising padding material,

[0007] The padding material is uneven.

[0008] The padding material has a wrinkled section, and the wrinkled section has a locking structure to prevent the wrinkled section from loosening.

[0009] The paper pad of the present invention has a locking structure on the wrinkled part to prevent the wrinkled part of the padding material from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of uneven padding material. The paper pad of the present invention can be used to fill the corner space of packaging boxes in logistics, ensuring that the items will not move inside the packaging box, and is suitable for wrapping and shock-absorbing small items. It requires a small amount and saves costs. In addition, the paper pad can be divided into different specifications according to the needs of the scenario, and can also be used for the packaging cushioning of other larger objects.

[0010] In some embodiments, a first body and a second body can be formed on both sides of the wrinkled portion of the padding material, respectively.

[0011] The locking structure may include a first extension and a perforation on the constricted portion.

[0012] One end of the first extension is located on either the first body or the second body.

[0013] The other end of the first extension passes through the perforation and is set at an angle, or the other end of the first extension passes through the perforation and is attached to the other of the first body and the second body.

[0014] Therefore, after passing through the perforation, the first extension is inclined or attached to one of the first body and the second body. In this way, the first extension can lock the wrinkled part, prevent the wrinkled part on the padding material from loosening, and ensure that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0015] In some embodiments, a first body and a second body can be formed on both sides of the wrinkled portion of the padding material, respectively.

[0016] The locking structure may include a second extension, one end of which is disposed on either the first body or the second body, the second extension overlaps the wrinkled portion, and the other end of the second extension is arranged at an acute angle to either the first body or the second body, or the other end of the second extension is attached to either the first body or the second body.

[0017] Therefore, after the second extension overlaps the wrinkled part, its free end is arranged at an acute angle to one of the first body and the second body or is attached to one of the first body and the second body. In this way, the second extension can lock the wrinkled part, prevent the wrinkled part on the padding material from loosening, and ensure that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0018] In some embodiments, a first body and a second body can be formed on both sides of the wrinkled portion of the padding material, respectively.

[0019] The locking structure may include a second extension and a through groove provided on the wrinkled portion. One end of the second extension is provided on either the first body or the second body. The second extension is accommodated in the through groove. The other end of the second extension is arranged at an acute angle to either the first body or the second body, or the other end of the second extension is attached to either the first body or the second body.

[0020] Therefore, after the second extension is accommodated in the through groove on the wrinkled part, its free end is arranged at an acute angle to one of the first body and the second body or attached to one of the first body and the second body. In this way, the second extension can lock the wrinkled part, prevent the wrinkled part on the padding material from loosening, and ensure that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0021] In some embodiments, the locking structure can be formed by folding the wrinkled portion at least twice. This at least two folds prevent the wrinkled portion on the padding material from loosening, ensuring the paper pad remains compact and thus improving the cushioning effect of the padding material.

[0022] In some embodiments, the locking structure can be formed by folding the wrinkled portion in half. This folding prevents the wrinkled portion on the padding material from loosening, ensuring the paper pad remains compact and thus improving the cushioning effect of the padding material.

[0023] In some implementations, the locking structure can be formed by bending the wrinkled portion. This bending prevents the wrinkled portion on the padding material from loosening, ensuring the paper pad remains compact and thus improving the cushioning effect of the padding material.

[0024] In some embodiments, the locking structure can be formed by bonding the padding materials located within the wrinkled portion together. Thus, the bonding of the padding materials within the wrinkled portion locks the wrinkled portion in place, preventing it from loosening and ensuring the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0025] In some embodiments, a third body and a fourth body are formed on both sides of the padding material, respectively.

[0026] The locking structure can be formed by the third body being V-shaped or by folding the third body in half.

[0027] Therefore, the V-shape of the third body or the folding of the third body can prevent the wrinkles on the padding material from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0028] In some embodiments, a third body and a fourth body can be formed on both sides of the padding material, respectively.

[0029] The locking structure can be formed by the fourth body being V-shaped or by folding the fourth body in half.

[0030] Therefore, the fourth body being V-shaped or folded in half can prevent the wrinkled parts on the padding material from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0031] In some embodiments, a third body and a fourth body are formed on both sides of the padding material, respectively.

[0032] The locking structure can be formed by a third body being planar and a fourth body being V-shaped, or by a third body being planar and a fourth body being folded.

[0033] Therefore, having the third body in a planar shape and the fourth body in a V-shape, or having the third body in a planar shape and the fourth body in a folded shape, makes it less likely for the wrinkled parts on the padding material to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0034] In some embodiments, a third body and a fourth body can be formed on both sides of the padding material, respectively.

[0035] The locking structure can be formed by the fourth body being planar and the third body being V-shaped, or by the fourth body being planar and the third body being folded.

[0036] Therefore, if the fourth body is planar and the third body is V-shaped, or if the fourth body is planar and the third body is folded, the wrinkles on the padding material will not easily loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0037] In some embodiments, the padding material may be corrugated, or its surface may be serrated, wavy, or corrugated. Thus, padding materials with corrugated, serrated, wavy, or corrugated surfaces can ensure the cushioning effect of the padding material.

[0038] In some embodiments, the folding direction of the wrinkled portion can be along the width or length direction of the padding material. Thus, when the folding direction of the wrinkled portion is along the width direction of the padding material, the middle region of the padding material is squeezed from both sides, and the middle region of the padding material is clamped and squeezed / compressed to form the wrinkled portion. When the folding direction of the wrinkled portion is along the length direction of the padding material, the padding material can be cut into several sub-padding materials of a certain length along the length direction, and then the middle region of each sub-padding material can be clamped and squeezed / compressed along the length direction of the padding material to form the wrinkled portion on the sub-padding material.

[0039] According to another aspect of the present invention, a method for forming a paper pad is also provided, comprising the following steps:

[0040] a. Conveying padding material;

[0041] b. Crinkle the padding material;

[0042] c. Extruding the padding material to form wrinkles increases the wrinkling density in the area where the wrinkles are located;

[0043] d. Separate the extruded pad material into paper pads of the required length.

[0044] The molding method of the present invention, the wrinkled part formed by extruding the padding material can ensure that the paper pad remains compact, thereby improving the cushioning effect of the uneven padding material. The formed paper pad can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move inside the packaging box. It is also suitable for wrapping and shock absorbing small items. The amount used is small, saving costs. In addition, the paper pad can be divided into different specifications according to the needs of the scenario, and it can also be used for the packaging cushioning of other larger objects.

[0045] In some implementations, the following steps may be included after step c:

[0046] c'. Lock the wrinkled part by piercing the wrinkled part with teeth or needles, and the resulting latch is attached to one side of the wrinkled part or arranged at an acute angle to one side of the wrinkled part.

[0047] This way, the wrinkles can be locked in, preventing the wrinkles on the padding material from loosening and ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0048] In some implementations, the following steps may be included after step c:

[0049] c'. Lock the wrinkled part by folding the wrinkled part at least twice.

[0050] Therefore, after the wrinkled part is folded at least twice, the wrinkled part on the padding material will not easily loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0051] In some implementations, the following steps may be included after step c:

[0052] c'. Lock the wrinkled part by folding it in half.

[0053] Therefore, folding the wrinkled part in half makes it less likely for the wrinkled part on the padding material to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0054] In some implementations, the following steps may be included after step c:

[0055] c'. Lock the wrinkled part by squeezing it into a V shape.

[0056] Therefore, by squeezing the wrinkled parts into a V-shape, the wrinkled parts on the padding material are less likely to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0057] In some implementations, the following steps may be included after step c:

[0058] c'. Lock the wrinkled part by folding one side of the wrinkled part in half.

[0059] Therefore, folding one side of the wrinkled part in half can prevent the wrinkled part on the padding material from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0060] In some implementations, the following steps may be included after step c:

[0061] c'. Lock the wrinkled part by keeping one side of the wrinkled part flat and the other side in a V shape or folded in half.

[0062] Therefore, by keeping one side of the wrinkled part flat and the other side in a V shape or folding it in half, the wrinkled part on the padding material will not easily loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material.

[0063] In some implementations, the following steps may be included after step c:

[0064] c'. Lock the wrinkled part by setting a fastening part on the wrinkled part. One end of the fastening part is fixed to one side of the wrinkled part and fastened to the wrinkled part. The other end of the fastening part is arranged at an acute angle to the other side of the wrinkled part or attached to the other side of the wrinkled part.

[0065] Therefore, the snap-fit ​​part can lock the wrinkled part, prevent the wrinkled part on the padding material from loosening, and ensure that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0066] In some implementations, the following steps may be included after step c:

[0067] c'. Lock the wrinkled part by tearing off a portion of the wrinkled part and folding the torn portion so that it is arranged at an acute angle to one side of the wrinkled part or attached to one side of the wrinkled part.

[0068] Therefore, the torn portion on the wrinkled part can lock the wrinkled part, preventing the wrinkled part on the padding material from loosening and ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0069] In some implementations, the following steps may be included after step c:

[0070] c'. Lock the wrinkled part by using tape to bind and secure it.

[0071] Therefore, by using tape to bind and secure the wrinkled parts, the wrinkled parts can be locked in place, preventing them from loosening and ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad.

[0072] In some implementations, the following steps may be included after step b:

[0073] b'. Apply adhesive to the troughs and creases in the middle area of ​​the padding material.

[0074] In step c, when the central region of the pad is squeezed, the folds in the central region of the pad adhere to each other to form a wrinkled section.

[0075] Therefore, the wrinkled area formed by the mutual adhesion of the folds in the middle area of ​​the padding material can prevent the padding material from loosening at the wrinkled area, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the padding material.

[0076] In some embodiments, in step a, the padding material may be wrinkled, or the surface of the padding material may be serrated, or the surface of the padding material may be wavy, or the surface of the padding material may be corrugated. Thus, padding materials with wrinkled, serrated, wavy, or corrugated surfaces can ensure the cushioning effect of the padding material.

[0077] In some embodiments, in step c, the folding direction of the wrinkled portion can be along the width or length direction of the padding material. Thus, when the folding direction of the wrinkled portion is along the width direction of the padding material, the wrinkled portion is formed by squeezing the middle region of the padding material from both sides and clamping / compressing the middle region of the padding material. When the folding direction of the wrinkled portion is along the length direction of the padding material, the padding material can be first cut into several sub-padding materials of a certain length along the length direction, and then the wrinkled portion on the sub-padding material can be formed by clamping / compressing the middle region of each sub-padding material along the length direction of the padding material.

[0128] Example 5:

[0129] Figure 6 The structure of a paper pad according to a fifth embodiment of the present invention is shown schematically.

[0130] Reference 6, a paper mat, comprising matting material 1.

[0131] In this embodiment, only the locking structure is different from that in Embodiment 4; everything else is the same and will not be described again.

[0132] refer to Figure 6 In this embodiment, the locking structure can be formed by folding the wrinkled portion 11 in half. The formation process of the wrinkled portion 11 can be referred to Figure 1 → Figure 6 The style changes; after the wrinkled part 11 is folded in half, the wrinkled part 11 on the padding material 1 will not easily loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material 1.

[0133] In other embodiments, the locking structure may also be formed by bending the wrinkled portion 11. After bending, the wrinkled portion 11 on the pad material 1 is not easy to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0134] In other embodiments, the locking structure can also be formed by bonding the padding materials 1 located within the wrinkled portion 11 together. The locking structure can be formed by dripping glue at the trough of the wrinkles in the middle region of the padding material 1, and then squeezing the middle region of the padding material 1. The wrinkles in the middle region of the padding material 1 bond together to form a locking structure to lock the wrinkled portion 11. After the padding materials 1 within the wrinkled portion 11 bond together, the wrinkled portion 11 can be locked to prevent the wrinkled portion 11 on the padding material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the padding material 1.

[0135] The paper pad of the present invention has a locking structure on the wrinkled portion 11 to prevent the wrinkled portion 11 on the padding material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven padding material 1. The paper pad of the present invention can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move inside the packaging box, and is suitable for wrapping and shock absorbing small items. It requires a small amount and saves costs. In addition, the paper pad can be divided into different specifications according to the needs of the scenario, and can also be used for the packaging cushioning of other larger items.

[0136] Example 6:

[0137] Figure 7 The structure of a paper pad according to a sixth embodiment of the present invention is shown schematically.

[0138] Reference 7, a paper mat, comprising matting material 1.

[0139] The padding material 1 is uneven. Specifically, the style of the padding material 1 can be: the padding material 1 is wrinkled, or the surface of the padding material 1 is serrated, or the surface of the padding material 1 is wavy, or the surface of the padding material 1 is corrugated. The padding material 1 with wrinkled, serrated, wavy, or corrugated surface can ensure the cushioning effect of the padding material 1.

[0140] refer to Figure 7 The pad material 1 has a wrinkled portion 11 formed on it. The wrinkled portion 11 is in a gathered shape and can be formed by clamping and squeezing / compressing the middle area of ​​the pad material 1.

[0141] refer to Figure 7 The wrinkle direction of the wrinkled portion 11 can be along the width direction of the padding material 1 or along the length direction of the padding material 1. When the wrinkle direction of the wrinkled portion 11 is along the width direction of the padding material 1, Figure 7 When the middle region of the pad 1 is squeezed from both the upper and lower sides (as shown in the vertical direction), the wrinkled part 11 is formed by clamping and squeezing / compressing the middle region of the pad 1. When the wrinkle direction of the wrinkled part 11 is along the length direction of the pad 1 (as shown in the vertical direction), the wrinkled part 11 is formed by squeezing and squeezing / compressing the middle region of the pad 1. Figure 7 When the pad material 1 is cut into several sub-pad materials of a certain length along the length direction (as shown in the left and right directions), the middle area of ​​each sub-pad material can be clamped and squeezed / compressed along the length direction of the pad material 1 to form the wrinkled part 11 on the sub-pad material.

[0142] A locking structure is provided on the wrinkled part 11. The locking structure on the wrinkled part 11 can prevent the wrinkled part 11 on the padding material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven padding material 1.

[0143] refer to Figure 7 The second and third bodies 103 and the fourth body 104 are formed on the two sides of the pad material 1, respectively.

[0144] refer to Figure 7 In this embodiment, the locking structure is formed by the third body 103 in a V shape. The V shape of the third body 103 can prevent the wrinkled part 11 on the pad material 1 from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0145] In other embodiments, the locking structure may also be formed by folding the third body 103 in half. Folding the third body 103 in half makes the wrinkled portion 11 on the padding material 1 less likely to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material 1.

[0146] In other embodiments, the locking structure may also be formed by the fourth body 104 in a V shape, or by folding the fourth body 104 in half. The V shape or folding of the fourth body 104 can prevent the wrinkled portion 11 on the pad material 1 from loosening, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the pad material 1.

[0147] In other embodiments, the locking structure may also be formed by the third body 103 being planar and the fourth body 104 being V-shaped, or by the third body 103 being planar and the fourth body 104 being folded, or by the fourth body 104 being planar and the third body 103 being V-shaped or by the fourth body 104 being planar and the third body 103 being folded. In this way, the wrinkled portion 11 on the padding material 1 is not easy to loosen, ensuring that the paper pad remains compact, thereby improving the cushioning effect of the padding material 1.

[0148] The paper pad of the present invention has a locking structure on the wrinkled portion 11 to prevent the wrinkled portion 11 on the padding material 1 from loosening, ensuring that the paper pad always remains compact, thereby improving the cushioning effect of the uneven padding material 1. The paper pad of the present invention can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move inside the packaging box, and is suitable for wrapping and shock absorbing small items. It requires a small amount and saves costs. In addition, the paper pad can be divided into different specifications according to the needs of the scenario, and can also be used for the packaging cushioning of other larger items.

[0149] Figure 8 The diagram schematically illustrates the process of forming a paper pad according to one embodiment of the present invention.

[0150] refer to Figure 8 The method for forming paper pads includes the following steps:

[0151] S101: Conveying mat material.

[0152] S102: Wrinkle the padding material;

[0153] The methods for wrinkling the padding material are as follows: the padding material can be wrinkled by passing through a wavy forming channel, or by pressing the padding material with upper and lower wavy rollers or pressure plates, or by extruding the padding material with front and rear differential rollers.

[0154] The crease direction of the padding material can be along the width direction of the padding material or along the length direction of the padding material. Of course, it can be along any other direction of the padding material, without any particular limitation.

[0155] The wrinkled padding material is uneven. Specifically, the style of the wrinkled padding material can be selected as follows: the padding material is wrinkled, or the surface of the padding material is serrated, or the surface of the padding material is wavy, or the surface of the padding material is corrugated. The padding material with wrinkled, serrated, wavy, or corrugated surface can ensure the cushioning effect of the padding material.

[0156] S103: Extruding padding material to form wrinkles to increase the wrinkling density in the area where the wrinkles are located;

[0157] The middle area of ​​the padding material is clamped and squeezed / compressed. Preferably, the squeezing direction coincides with the folding direction. A cylinder-driven clamping device can be used to squeeze the padding material. The squeezing direction can also not coincide with the folding direction and be tilted at a certain angle. During the process of squeezing the padding material to form a wrinkled part, the wrinkling density in the area where the wrinkled part is located increases, ensuring the cushioning effect of the padding material.

[0158] The wrinkle direction of the wrinkled part can be along the width or length of the padding material. When the wrinkle direction is along the width of the padding material, the middle area of ​​the padding material is squeezed from both sides. The wrinkled part is formed by clamping and squeezing / compressing the middle area of ​​the padding material. When the wrinkle direction is along the length of the padding material, the padding material can be cut into several sub-padding materials of a certain length along the length. Adjacent sub-padding materials can be completely cut or not completely cut. When not completely cut, only the middle area between adjacent sub-padding materials is cut to facilitate the squeezing and forming of the wrinkled part. Then, the middle area of ​​each sub-padding material is clamped and squeezed / compressed along the length of the padding material to form the wrinkled part on the sub-padding material.

[0159] S104: Separate the extruded pad material into paper pads of the required length;

[0160] Tear lines, indentations, or easy-tear lines can be pre-set on the padding material, allowing the compressed padding material to be separated into paper pads of the required length by tearing or cutting.

[0161] The molding method of the present invention, the wrinkled part formed by extruding the padding material can ensure that the paper pad remains compact, thereby improving the cushioning effect of the uneven padding material. The formed paper pad can be used to fill the corner space of the packaging box in logistics, ensuring that the items will not move inside the packaging box. It is also suitable for wrapping and shock absorbing small items. The amount used is small, saving costs. In addition, the paper pad can be divided into different specifications according to the needs of the scenario, and it can also be used for the packaging cushioning of other larger objects.

[0167] The crease direction of the padding material can be along the width direction of the padding material or along the length direction of the padding material. Of course, it can be along any other direction of the padding material, without any particular limitation.

[0168] The wrinkled padding material is uneven. Specifically, the style of the wrinkled padding material can be selected as follows: the padding material is wrinkled, or the surface of the padding material is serrated, or the surface of the padding material is wavy, or the surface of the padding material is corrugated. The padding material with wrinkled, serrated, wavy, or corrugated surface can ensure the cushioning effect of the padding material.

[0169] S203: Extruding padding material to form wrinkles to increase the wrinkling density in the area where the wrinkles are located;

[0170] The middle area of ​​the padding material is clamped and squeezed / compressed. Preferably, the squeezing direction coincides with the folding direction. A cylinder-driven clamping device can be used to squeeze the padding material. The squeezing direction can also not coincide with the folding direction and be tilted at a certain angle. During the process of squeezing the padding material to form a wrinkled part, the wrinkling density in the area where the wrinkled part is located increases, ensuring the cushioning effect of the padding material.

[0171] The wrinkle direction of the wrinkled part can be along the width or length of the padding material. When the wrinkle direction is along the width of the padding material, the middle area of ​​the padding material is squeezed from both sides. The wrinkled part is formed by clamping and squeezing / compressing the middle area of ​​the padding material. When the wrinkle direction is along the length of the padding material, the padding material can be cut into several sub-padding materials of a certain length along the length. Adjacent sub-padding materials can be completely cut or not completely cut.
