Description

Technical Field

[0001] The utility model relates to a cushion material unit, a forming component and a cushion material forming machine. Background Art

[0002] During the transportation process, items will be packaged accordingly according to their different characteristics. For example, some fragile items may easily break due to vibration and collision during transportation.

[0003] At present, cushioning materials are generally wrapped around these fragile items, or cushioning materials are filled into the packaging box to provide shockproof protection. Common cushioning wrapping materials include bubble paper, which has ridges and depressions on the paper. Each ridge is hollow inside. Each ridge on the front of the bubble paper forms a depression on the back of the bubble paper, that is, each ridge on the front of the bubble paper corresponds to a depression on the back. Due to the presence of ridges and depressions, the paper becomes three-dimensional and has a deformation space after wrapping, which provides a cushioning effect.

[0004] The existing bubble paper is generally formed by rolling a pair of forming rollers. The surface of the forming rollers has protrusions and grooves. The protrusions and grooves of the pair of forming rollers cooperate with each other to process and form the paper. However, since the protrusions and grooves on the forming rollers are generally of the same shape and are regularly spaced, the protrusions and pits on the formed bubble paper are also regular. Moreover, a bubble paper unit with protrusions and pits regularly spaced can be formed on the paper by rotating the pair of forming rollers once. The size of the bubble paper unit along the conveying direction is consistent with the circumference of the forming rollers. The size of the bubble paper unit perpendicular to the conveying direction is the width of the bubble paper itself. When winding objects, it is very easy for the bubble paper wound later to completely overlap the bubble paper wound earlier, that is, the protrusions on the bubble paper wound later are completely stuck in the pits on the bubble paper wound earlier and the pits on the bubble paper wound later are completely stuck on the protrusions on the bubble paper wound earlier. In this case, it is equivalent to wrapping two layers of bubble paper but only having the effect of one layer, which greatly reduces the cushioning effect on the objects.

[0005] Therefore, how to reduce the probability of two layers of bubble wrap for packaging items being completely overlapped is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a cushion material unit, a forming assembly and a cushion material forming machine to solve at least one of the above technical problems.

[0007] According to one aspect of the utility model, a cushion material unit is provided, comprising a body,

[0008] The main body is provided with a plurality of protrusions.

[0009] At least two protrusions have different cross-sectional shapes, heights or maximum cross-sectional areas.

[0010] In the cushion material unit of the utility model, since at least two protrusions have different cross-sectional shapes, heights or maximum cross-sectional areas, when packaging articles, the sizes of the two layers of bubble paper used for packaging are unlikely to be exactly the same. In this case, when the two layers of bubble paper are stacked together, the areas where the protrusions having different cross-sectional shapes, heights or maximum cross-sectional areas from other protrusions are located are unlikely to completely overlap. This can prevent the two layers of bubble paper used for packaging articles from completely overlapping each other, thereby ensuring the three-dimensionality of the bubble paper after being rolled, and improving the cushioning and shock-resistant effects on the articles.

[0011] In some embodiments, the cross-sectional shape of the protrusion may be a polygon or an ellipse. Thus, the design of at least two protrusions with different cross-sectional shapes can prevent the two layers of bubble paper for packaging items from being completely overlapped with each other with a high probability, ensure the three-dimensionality of the bubble paper after being rolled, and improve the cushioning and shock-resistant effect on the items.

[0012] In some embodiments, the plurality of protrusions may be arranged in a matrix, whereby the plurality of protrusions arranged in a matrix may uniformly provide shockproof protection to the article.

[0013] According to one aspect of the utility model, there is also provided a cushion material unit, comprising a body,

[0014] The main body is provided with M protrusions and N recesses.

[0015] At least one and at most M-1 protrusions are arranged at non-equidistant intervals from all adjacent pits, or at least one and at most N-1 pits are arranged at non-equidistant intervals from all adjacent protrusions.

[0016] In the cushion material unit of the utility model, since at least one and at most M-1 protrusions are arranged at non-equidistant intervals from all adjacent pits, that is, the protrusions in the area where the protrusions arranged at non-equidistant intervals from all adjacent pits are located are arranged in a staggered manner compared to other areas, when packaging articles, because the sizes of the two layers of bubble paper used for packaging are unlikely to be exactly the same, when the two layers of bubble paper are stacked together, the areas where the staggered protrusions are located are unlikely to completely overlap, thereby being able to avoid the two layers of bubble paper for packaging articles from completely overlapping each other, ensuring the three-dimensional degree of the bubble paper after being rolled, and improving the cushioning effect on the articles. Impact and shock-resistant effect; since at least one and at most N-1 pits are arranged at non-equidistant intervals from all adjacent protrusions, that is, the pits in the area where the pits are arranged at non-equidistant intervals from all adjacent protrusions are located are staggered compared to other areas, when packaging items, because the sizes of the two layers of bubble paper used for packaging are unlikely to be exactly the same, when the two layers of bubble paper are stacked together, the areas where the staggered pits are located are unlikely to completely overlap, thereby avoiding the two layers of bubble paper for packaging items from completely overlapping each other with a high probability, ensuring the three-dimensional degree of the bubble paper after winding, and improving the cushioning and shock-resistant effect on the items.

[0017] In some embodiments, the protrusions and pits in other areas other than the protrusions arranged at non-equidistant intervals with all adjacent pits are arranged in a matrix, or the protrusions and pits in other areas other than the pits arranged at non-equidistant intervals with all adjacent protrusions are arranged in a matrix. Thus, the protrusions and pits in other areas other than the staggered protrusions are arranged in a matrix, which can provide uniform anti-seismic protection to the article to the greatest extent, and the protrusions and pits in other areas other than the staggered pits are arranged in a matrix, which can provide uniform anti-seismic protection to the article to the greatest extent.

[0018] According to one aspect of the utility model, there is also provided a cushion material unit, comprising a body,

[0019] There are N protrusions on the body.

[0020] The arrangement angle of at least one and at most N-1 protrusions along the length direction or the width direction of the mat material unit is different from that of other protrusions.

[0021] In the cushion material unit of the utility model, since at least one and at most N-1 protrusions have an arrangement angle different from other protrusions along the length direction or the width direction of the cushion material unit, when packaging articles, because the sizes of the two layers of bubble paper used for packaging are unlikely to be exactly the same, when the two layers of bubble paper are stacked together, the areas where the protrusions with different arrangement angles from other protrusions are located are unlikely to completely overlap, thereby avoiding the two layers of bubble paper for packaging articles from completely overlapping each other with a high probability, ensuring the three-dimensional degree of the bubble paper after winding, and improving the cushioning and shock-resistant effects on the articles.

[0022] In some embodiments, the cross-sectional shape of the protrusions may be a polygon or an ellipse excluding a circle. Thus, the protrusions with a polygonal or elliptical cross-sectional shape excluding a circle can have a different arrangement angle from other protrusions as long as at least one and at most N-1 protrusions rotate at a certain angle. In this way, when two layers of bubble wrap are stacked together, the areas where the protrusions with different arrangement angles from other protrusions are located are unlikely to completely overlap, thereby being able to avoid the two layers of bubble wrap for packaging items from completely overlapping each other, ensuring the three-dimensionality of the bubble wrap after rolling, and improving the cushioning and shock-resistant effect on the items.

[0023] In some embodiments, the N protrusions may be arranged in a matrix, whereby the plurality of protrusions arranged in a matrix may uniformly provide shockproof protection to the article.

[0024] According to another aspect of the utility model, a molding assembly is also provided, comprising at least two moldings, on which are provided a plurality of protrusions and a plurality of grooves, wherein the protrusions on at least one of the two moldings cooperate with the grooves on the other molding, and the grooves on one molding cooperate with the protrusions on the other molding, and the protrusions and grooves of at least two moldings cooperate with each other to process the cushioning unit to form the aforementioned protrusions.

[0025] After the molding component of the utility model processes the cushion material unit, corresponding protrusions can be formed on the cushion material unit, thereby forming bubble paper, each protrusion is hollow inside, and each protrusion on the front side of the bubble paper will form a pit on the back side of the bubble paper, that is, each protrusion on the front side of the bubble paper corresponds to a pit on the back side. When the formed bubble paper is used to pack articles, it is highly likely that the two layers of bubble paper for packing the articles will not be completely overlapped, thereby ensuring the three-dimensional degree of the bubble paper after winding and improving the cushioning and shock-resistant effect on the articles.

[0026] In some embodiments, the forming body may be in a roller style, a synchronous belt style, or a pressure plate style. Thus, two roller style forming bodies may cooperate with each other to process the cushion unit to form the aforementioned protrusion, two synchronous belt style forming assemblies may cooperate with each other to process the cushion unit to form the aforementioned protrusion, or two pressure plate style forming assemblies may cooperate with each other to process the cushion unit to form the aforementioned protrusion.

[0027] In some embodiments, at least two forming bodies may be any two of roller style, synchronous belt style, and pressure plate style. Thus, a roller style forming body and a synchronous belt style forming body may cooperate with each other to process the mat material unit to form the aforementioned protrusion, or a roller style forming body and a pressure plate style forming body may cooperate with each other to process the mat material unit to form the aforementioned protrusion, or a synchronous belt style forming body and a pressure plate style forming body may cooperate with each other to process the mat material unit to form the aforementioned protrusion.

[0028] According to another aspect of the utility model, a cushion material forming machine is also provided, including a machine body, a driving device and the aforementioned forming assembly, wherein the driving device and the forming assembly are both arranged on the machine body, and the driving device can drive the forming assembly to move to process the cushion material unit to form the aforementioned protrusion.

[0029] The cushion material forming machine of the utility model, under the action of the driving device, the raised parts and the groove parts on the forming components cooperate with each other to process the cushion material unit, and the paper material is pushed into the groove part of the other forming body by the raised part on one forming body, thereby realizing the forming of the raised parts on the cushion material unit, thereby forming bubble paper, each raised part is hollow inside, and each raised part on the front side of the bubble paper will form a pit on the back side of the bubble paper, that is, each raised part on the front side of the bubble paper corresponds to a pit on the back side, and when the formed bubble paper is used to pack articles, it is possible to avoid the two layers of bubble paper for packing the articles from being completely overlapped with each other with a high probability, thereby ensuring the three-dimensional degree of the bubble paper after winding, and improving the cushioning and shock-resistant effect on the articles.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0039] Figure 1 and Figure 2 The pattern of existing bubble wrap is schematically shown.

[0040] refer to Figure 1 and Figure 2 The existing bubble paper has regularly arranged protrusions 100 and pits 200, each protrusion 100 is hollow inside, and each protrusion 100 on the front side of the bubble paper will form a pit 200 on the back side of the bubble paper, that is, each protrusion 100 on the front side of the bubble paper corresponds to a pit 200 on the back side, and each pit 200 on the front side of the bubble paper will form a protrusion 100 on the back side of the bubble paper, that is, each pit 200 on the front side of the bubble paper corresponds to a protrusion 100 on the back side. Due to the existence of the protrusions 100 and the pits 200, the paper becomes three-dimensional, and has a deformation space after wrapping, which plays a buffering effect.

[0041] Since the arrangement of the protrusions 100 and the pits 200 on the existing bubble paper is regular, when winding an object, it is very easy for the bubble paper wound later to completely overlap the bubble paper wound earlier, that is, the protrusions 100 on the bubble paper wound later are completely stuck in the pits 200 on the bubble paper wound earlier, and the pits 200 on the bubble paper wound later are completely stuck on the protrusions 100 on the bubble paper wound earlier. In this case, it is equivalent to wrapping two layers of bubble paper but having the effect of only one layer, which greatly reduces the cushioning effect on the object.

[0042] Figure 3 The structure of a cushion material unit according to an embodiment of the utility model is schematically shown.

[0043] refer to Figure 3 A cushion material unit comprises a main body 1, which is a paper material.

[0044] Taking the forming component as a pair of forming rollers as an example, in this embodiment, the cushioning material unit refers to a bubble paper unit with regularly spaced protrusions and pits formed on the paper material when a pair of forming rollers rotate one circle, and the size of the bubble paper unit along the conveying direction is consistent with the circumference of the forming rollers, and the size of the bubble paper unit perpendicular to the conveying direction is the width of the bubble paper itself. The bubble paper is usually formed by multiple bubble paper units arranged regularly along the length direction of the bubble paper.

[0045] refer to Figure 3 A plurality of protrusions 11 are formed on the main body 1 , and each protrusion 11 on the front side of the main body 1 forms a recess 12 on the back side of the main body 1 , and each recess 12 on the front side of the main body 1 forms a protrusion 11 on the back side of the main body 1 .

[0046] refer to Figure 3 In this embodiment, on the front side of the main body 1, each row has protrusions 11 and recesses 12 arranged at intervals, each column has protrusions 11 and recesses 12 arranged at intervals, and the protrusions 11 and recesses 12 are arranged in a matrix. The protrusions 11 and recesses 12 arranged in a matrix can uniformly provide shock-proof protection for items.

[0047] refer to Figure 3, at least two protrusions 11 on the body 1 have different cross-sectional shapes, specifically: in this embodiment, the cross-sectional shape of the protrusion 11 in the fourth row and fifth column is square, and the protrusion 11 will form a pit 12 with a square cross-sectional shape on the back of the bubble paper, and the cross-sectional shapes of the other protrusions 11 and pits 12 are circular; during the packaging process, if the sizes of the two layers of bubble paper are exactly the same and the arrangement and positions of the protrusions 11 and pits 12 on the two layers of bubble paper are exactly the same, then the two layers of bubble paper will still completely overlap when they are aligned and stacked together, but in the actual operation process, the size of the bubble paper torn off by the operator each time is unlikely to be exactly the same (unless measured with a ruler each time, the probability of this method is basically 0), that is, each time the staff packs The sizes of the two layers of bubble wrap are unlikely to be exactly the same, and the two layers of bubble wrap will unlikely be aligned and stacked together for packaging. In this case, during the packaging process, when the two layers of bubble wrap are stacked together, the areas where the protrusions 11 (square in cross-sectional shape) having a cross-sectional shape different from other protrusions 11 (circular in cross-sectional shape) are located (such as the area where the protrusions 11 in the fourth row and fifth column are located) are unlikely to completely overlap, that is, the protrusions 11 with a square cross-sectional shape on the first layer of bubble wrap are unlikely to be stuck in the recesses 12 with a square cross-sectional shape on the second layer of bubble wrap, thereby avoiding the two layers of bubble wrap for packaging items from completely overlapping each other with a high probability, ensuring the three-dimensionality of the bubble wrap after winding, and improving the cushioning and shock-resistant effects on the items.

[0048] In other embodiments, as needed, the cross-sectional shapes of at least three protrusions 11 on the main body 1 may be different. In this way, when packaging items, it is more likely that the two layers of bubble paper for packaging the items will not be completely overlapped, thereby ensuring the three-dimensionality of the bubble paper after rolling and improving the cushioning and shock-resistant effect on the items.

[0049] refer to Figure 3 In this embodiment, the cross-sectional shape of the protrusion 11 in the fourth row and fifth column is square, and the cross-sectional shape of the other protrusions 11 is circular. In other embodiments, the cross-sectional shape of the protrusion 11 can be adjusted as needed, such as a triangle, a pentagon, an ellipse, or other polygons, as long as at least two protrusions 11 have different cross-sectional shapes.

[0050] A molding assembly includes at least two moldings, on which a plurality of protrusions and a plurality of grooves are formed, wherein the protrusions on one of the at least two moldings cooperate with the grooves on the other molding, and the grooves on one molding cooperate with the protrusions on the other molding, and the protrusions and grooves on the at least two moldings cooperate with each other to process a mat unit to form Figure 3The protrusions 11 and the pits 12 shown in the figure form bubble paper. When the bubble paper is used to pack items, it is highly likely that the two layers of bubble paper used to pack the items will not be completely overlapped, thereby ensuring the three-dimensionality of the bubble paper after being rolled and improving the cushioning and shock-resistant effect on the items.

[0051] The forming body can be a roller body type, a synchronous belt type or a pressure plate type, as long as the forming body is formed with a material that can be processed to form a mat unit Figure 3 The protrusions 11 and the pits 12 shown in the figure may be in the form of multiple protrusions or multiple grooves; the number of the forming bodies in the forming assembly is preferably two, and the protrusions and grooves of the two forming bodies cooperate with each other to process the mat unit, and the mat unit can be processed by two roller-style forming bodies cooperating with each other to form Figure 3 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by cooperating with two synchronous belt-style forming bodies. Figure 3 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by cooperating with two press plate-style forming bodies. Figure 3 The protrusions 11 and the depressions 12 are shown.

[0052] The number of the forming bodies in the forming assembly is preferably two, and the raised portions and the groove portions of the two forming bodies cooperate with each other to process the mat unit. A roller-shaped forming body and a synchronous belt-shaped forming body can cooperate with each other to process the mat unit to form Figure 3 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by a roller-shaped forming body and a pressure plate-shaped forming body in cooperation with each other. Figure 3 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by a synchronous belt style forming body and a pressure plate style forming body cooperating with each other to form Figure 3 The protrusions 11 and the depressions 12 are shown.

[0053] A mat material forming machine comprises a machine body, a driving device and the aforementioned forming assembly, wherein the driving device and the forming assembly are both mounted on the machine body, and the driving device can drive the forming assembly to move to process the mat material unit, thereby forming Figure 3 The protrusions 11 and recesses 12 shown in the figure push the paper material into the groove part of another molded body through the protrusion part on one molded body, thereby realizing the molding of the protrusions 11 and recesses 12 on the cushion material unit, thereby forming bubble paper. When the formed bubble paper is used to pack articles, it is highly likely that the two layers of bubble paper used to pack the articles will not be completely overlapped, thereby ensuring the three-dimensional degree of the bubble paper after winding and improving the cushioning and shock-resistant effect on the articles.

[0054] Figure 4 The structure of the cushion material unit of the second embodiment of the present utility model is schematically shown.

[0055] refer to Figure 4 A cushion material unit comprises a main body 1, which is a paper material.

[0058] In this embodiment, the protrusions 11 and recesses on the upper surface of the body 1 are arranged in a matrix, and the protrusions 11 and recesses on the lower surface of the body 1 are also arranged in a matrix. The protrusions 11 and recesses arranged in a matrix can uniformly provide shockproof protection for items.

[0059] refer to Figure 4 , at least two protrusions 11 on the main body 1 have different heights, specifically: in this embodiment, the height of the first protrusion 11 from the left on the upper surface of the main body 1 is higher than the heights of the other protrusions 11, and the height of the first protrusion 11 from the left is also higher than the heights of the other protrusions 11 in the column and row where the protrusion 11 is located; during the packaging process, if the sizes of the two layers of bubble paper are exactly the same and the arrangement and positions of the protrusions 11 and the pits on the two layers of bubble paper are also exactly the same, then the two layers of bubble paper will still completely overlap when they are aligned and stacked together, but in the actual operation process, the sizes of the bubble paper torn off by the operator each time are unlikely to be exactly the same (unless a ruler is used to measure each time, and the probability of this method is basically 0) That is, the sizes of the two layers of bubble wrap used by the staff for packaging each time are unlikely to be exactly the same, and the two layers of bubble wrap will unlikely be aligned and stacked together when packaging items. In this case, when the two layers of bubble wrap are stacked together, the area where the protrusions 11 with a height different from the other protrusions 11 (such as the area where the first protrusion 11 from the left is located) is unlikely to be completely overlapped, that is, the protrusions 11 on the first layer of bubble wrap with a height different from the other protrusions 11 are unlikely to be stuck in the pits on the second layer of bubble wrap with a depth different from the other pits, thereby avoiding the two layers of bubble wrap for packaging items from being completely overlapped, ensuring the three-dimensional degree of the bubble wrap after winding, and improving the cushioning and shock-resistant effect on the items.

[0060] In other embodiments, as needed, at least three protrusions 11 on the main body 1 may have different heights. In this way, when packaging items, it is more likely that the two layers of bubble paper used to package the items will not overlap completely, thereby ensuring the three-dimensionality of the bubble paper after rolling and improving the cushioning and shock-resistant effect on the items.

[0061] Figure 5 The structure of the cushion material unit of the third embodiment of the present utility model is schematically shown.

[0062] refer to Figure 5 A cushion material unit comprises a main body 1, which is a paper material.

[0063] Taking the forming component as a pair of forming rollers as an example, in this embodiment, the cushioning material unit refers to a bubble paper unit with regularly spaced protrusions and pits formed on the paper material when a pair of forming rollers rotate one circle, and the size of the bubble paper unit along the conveying direction is consistent with the circumference of the forming rollers, and the size of the bubble paper unit perpendicular to the conveying direction is the width of the bubble paper itself. The bubble paper is usually formed by multiple bubble paper units arranged regularly along the length direction of the bubble paper.

[0064] refer to Figure 5 A plurality of protrusions 11 are formed on the main body 1 , and each protrusion 11 on the upper surface of the main body 1 will form a pit (not shown) on the lower surface of the main body 1 , and each pit (not shown) on the upper surface of the main body 1 will form a protrusion 11 on the lower surface of the main body 1 .

Specifically: in this embodiment, the maximum cross-sectional area of ​​the first protrusion 11 from the left on the upper surface of the body 1 is larger than the maximum cross-sectional area of ​​the other protrusions 11, and the maximum cross-sectional area of ​​the first protrusion 11 from the left is also larger than the maximum cross-sectional area of ​​the other protrusions 11 in the column and row where the protrusion 11 is located; during the packaging process, if the sizes of the two layers of bubble paper are exactly the same and the arrangement and positions of the protrusions 11 and the pits on the two layers of bubble paper are also exactly the same, then the two layers of bubble paper will still completely overlap when they are aligned and stacked together, but in the actual operation process, the size of the bubble paper torn off by the operator each time is unlikely to be exactly the same (unless a ruler is used to measure each time, the probability of this method is very high).

[0067] In other embodiments, as needed, the maximum cross-sectional areas of at least three protrusions 11 on the main body 1 may be different. In this way, when packaging items, it is more likely that the two layers of bubble paper used to package the items will not overlap completely, thereby ensuring the three-dimensionality of the bubble paper after rolling and improving the cushioning and shock-resistant effects on the items.

Figure 4 and Figure 5 The protrusions 11 and the pits shown can also be formed by processing the mat unit by cooperating with two press plate-style forming bodies. Figure 4 and Figure 5 The protrusions 11 and depressions are shown.

[0070] The number of the forming bodies in the forming assembly is preferably two, and the raised portions and the groove portions of the two forming bodies cooperate with each other to process the mat unit. A roller-shaped forming body and a synchronous belt-shaped forming body can cooperate with each other to process the mat unit to form Figure 4 and Figure 5 The protrusions 11 and the pits shown can also be formed by processing the mat unit by a roller-shaped forming body and a pressure plate-shaped forming body in cooperation with each other. Figure 4 and Figure 5 The protrusions 11 and the pits shown can also be formed by processing the mat unit by a synchronous belt style forming body and a pressure plate style forming body cooperating with each other to form Figure 4 and Figure 5 The protrusions 11 and depressions are shown.

[0071] A mat material forming machine comprises a machine body, a driving device and the aforementioned forming assembly, wherein the driving device and the forming assembly are both mounted on the machine body, and the driving device can drive the forming assembly to move to process the mat material unit, thereby forming Figure 4 and Figure 5 The protrusions 11 and recesses shown in the figure; the paper material is pushed into the groove portion of another molded body by the protrusion on one molded body, thereby realizing the molding of the protrusions 11 and recesses on the cushioning material unit, thereby forming bubble paper. When the formed bubble paper is used to pack articles, it is highly likely that the two layers of bubble paper used to pack the articles will not be completely overlapped, thereby ensuring the three-dimensional degree of the bubble paper after winding and improving the cushioning and shock-resistant effect on the articles.

[0072] Figure 6 The structure of the cushion material unit of the fourth embodiment of the present utility model is schematically shown.

[0073] refer to Figure 6 A cushion material unit comprises a main body 1, which is a paper material.

[0074] Taking the forming component as a pair of forming rollers as an example, in this embodiment, the cushioning material unit refers to a bubble paper unit with regularly spaced protrusions and pits formed on the paper material when a pair of forming rollers rotate one circle, and the size of the bubble paper unit along the conveying direction is consistent with the circumference of the forming rollers, and the size of the bubble paper unit perpendicular to the conveying direction is the width of the bubble paper itself. The bubble paper is usually formed by multiple bubble paper units arranged regularly along the length direction of the bubble paper.

[0075] refer to Figure 6 The main body 1 is formed with M protrusions 11 and N recesses 12. Each protrusion 11 on the front side of the main body 1 will form a recess 12 on the back side of the main body 1, and each recess 12 on the front side of the main body 1 will form a protrusion 11 on the back side of the main body 1.

[0076] refer to Figure 6 , on the body 1, at least one and at most M-1 protrusions 11 are arranged at non-equidistant intervals with all adjacent pits 12, specifically: in this embodiment, the protrusions 11 in the fifth row and fourth column are arranged at non-equidistant intervals with the four adjacent pits 12, that is, the protrusions 11 in the fifth row and fourth column are arranged in a staggered manner compared to the protrusions 11 in other areas; during the packaging process, if the sizes of the two layers of bubble paper are exactly the same and the arrangement and positions of the protrusions 11 and the pits 12 on the two layers of bubble paper are also exactly the same, then the two layers of bubble paper will still completely overlap when they are aligned and stacked together, but in the actual operation process, the size of the bubble paper torn off by the operator each time is unlikely to be exactly the same (unless measured with a ruler each time, the probability of this method is basically 0), that is, the sizes of the two layers of bubble paper used by the staff for packaging each time are unlikely to be exactly the same, and the two layers of bubble paper will unlikely to be aligned and stacked together for packaging when packaging items. In this case, when the two layers of bubble paper are stacked together, the staggered protrusions 11 ( Figure 6 The area where the protrusion 11 in the fifth row and fourth column is located is unlikely to be completely overlapped, that is, the protrusion 11 in the fifth row and fourth column on the first layer of bubble paper is unlikely to be inserted into the pit 12 corresponding to the protrusion 11 in the fifth row and fourth column on the second layer of bubble paper. This can prevent the two layers of bubble paper for packaging items from being completely overlapped with each other with a high probability, ensure the three-dimensional degree of the bubble paper after winding, and improve the cushioning and shock-resistant effect on the items.

[0077] refer to Figure 6 On the front side of the main body 1, the protrusions 11 and the pits 12 in other areas outside the protrusions 11 in the fourth column of the fifth row are arranged in a matrix. Similarly, on the back side of the main body 1, the protrusions 11 and the pits 12 in other areas outside the pits 12 in the fourth column of the fifth row are also arranged in a matrix. In this way, the objects can be evenly protected from shock to the greatest extent.

[0078] In other embodiments, as needed, at least two and at most M-1 protrusions 11 and all adjacent pits 12 may be arranged at unequal intervals on the main body 1. In this way, when packaging items, it is more likely that the two layers of bubble paper packaging the items will not be completely overlapped, thereby ensuring the three-dimensionality of the bubble paper after winding and improving the cushioning and shock-resistant effect on the items.

[0079] Since each protrusion 11 on the front side of the main body 1 corresponds to a pit 12 on the back side of the bubble paper, and each pit 12 on the front side of the main body 1 corresponds to a protrusion 11 on the back side of the bubble paper, similarly, the scheme of arranging at least one and at most N-1 pits 12 on the main body 1 and all adjacent protrusions 11 at non-equidistant intervals is consistent with the aforementioned scheme of arranging at least one and at most M-1 protrusions 11 and all adjacent pits 12 at non-equidistant intervals, and will not be repeated here.

[0080] Figure 7 The structure of the cushion material unit of the fifth embodiment of the present utility model is schematically shown.

[0081] refer to Figure 7 A cushion material unit comprises a main body 1, which is a paper material.

[0082] Taking the forming component as a pair of forming rollers as an example, in this embodiment, the cushioning material unit refers to a bubble paper unit with regularly spaced protrusions and pits formed on the paper material when a pair of forming rollers rotate one circle, and the size of the bubble paper unit along the conveying direction is consistent with the circumference of the forming rollers, and the size of the bubble paper unit perpendicular to the conveying direction is the width of the bubble paper itself. The bubble paper is usually formed by multiple bubble paper units arranged regularly along the length direction of the bubble paper.

[0083] refer to Figure 7 N protrusions 11 are formed on the main body 1 , and each protrusion 11 on the front side of the main body 1 forms a pit 12 on the back side of the main body 1 , and each pit 12 on the front side of the main body 1 forms a protrusion 11 on the back side of the main body 1 .

[0084] refer to Figure 7 In this embodiment, on the front side of the main body 1, each row has protrusions 11 and recesses 12 arranged at intervals, each column has protrusions 11 and recesses 12 arranged at intervals, and the protrusions 11 and recesses 12 are arranged in a matrix. The protrusions 11 and recesses 12 arranged in a matrix can uniformly provide shock-proof protection for items.

[0085] refer to Figure 7, on the body 1, at least one and at most N-1 protrusions 11 are arranged at different angles along the length direction or width direction of the cushion unit from other protrusions 11. Specifically: in this embodiment, the cross-sectional shape of the protrusion 11 is elliptical, and the protrusion 11 forms a pit 12 with an elliptical cross-sectional shape on the reverse side of the bubble paper. The protrusions 11 in the fourth row and fourth column are arranged at different angles along the length direction and width direction of the cushion unit from other protrusions 11, that is, the arrangement angle of the protrusions 11 in the fourth row and fourth column is formed by rotating the arrangement angles of other protrusions 11 by a certain angle; during the packaging process, if two layers of bubbles If the sizes of the two layers of bubble paper are exactly the same and the arrangement and positions of the protrusions 11 and the pits 12 on the two layers of bubble paper are exactly the same, then the two layers of bubble paper will still completely overlap when they are aligned and stacked together. However, in the actual operation process, the sizes of the bubble paper torn off by the operator each time are unlikely to be exactly the same (unless a ruler is used to measure each time, and the probability of this method is basically 0), that is, the sizes of the two layers of bubble paper used by the operator for packaging each time are unlikely to be exactly the same, and the two layers of bubble paper will unlikely be aligned and stacked together when packaging items. In this case, when the two layers of bubble paper are stacked together, the protrusions 11 ( Figure 7 The area where the protrusion 11 in the fourth row and fourth column is located is unlikely to be completely overlapped, that is, the protrusion 11 in the fourth row and fourth column on the first layer of bubble paper is unlikely to be inserted into the pit 12 corresponding to the protrusion 11 in the fourth row and fourth column on the second layer of bubble paper. This can prevent the two layers of bubble paper for packaging items from being completely overlapped with each other with a high probability, ensure the three-dimensional degree of the bubble paper after winding, and improve the cushioning and shock-resistant effect on the items.

[0086] In other embodiments, as needed, the main body 1 may have at least two and at most N-1 protrusions 11 whose arrangement angles along the length direction or width direction of the cushioning unit are different from those of other protrusions 11. In this way, when packaging items, it is more likely that the two layers of bubble paper used to package the items will not be completely overlapped, thereby ensuring the three-dimensionality of the bubble paper after being rolled and improving the cushioning and shock-resistant effects on the items.

[0087] refer to Figure 7 In this embodiment, the cross-sectional shape of the protrusion 11 is an ellipse excluding a circle. In other embodiments, the cross-sectional shape of the protrusion 11 can be adjusted as needed, such as a triangle, a square, a pentagon, or other polygons, as long as at least one and at most N-1 protrusions 11 are arranged at different angles along the length direction or width direction of the mat unit than other protrusions 11.

[0088] A molding assembly includes at least two moldings, on which a plurality of protrusions and a plurality of grooves are formed, wherein the protrusions on one of the at least two moldings cooperate with the grooves on the other molding, and the grooves on one molding cooperate with the protrusions on the other molding, and the protrusions and grooves on the at least two moldings cooperate with each other to process a mat unit to form Figure 6 and Figure 7 The corresponding protrusions 11 and pits 12 are formed in the bubble paper, so that when the bubble paper is used to pack items, it is highly likely that the two layers of bubble paper used to pack the items will not be completely overlapped, thereby ensuring the three-dimensionality of the bubble paper after being rolled and improving the cushioning and shock-resistant effect on the items.

[0089] The forming body can be a roller body type, a synchronous belt type or a pressure plate type, as long as the forming body is formed with a material that can be processed to form a mat unit Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown in the figure may be in the form of multiple protrusions or multiple grooves; the number of the forming bodies in the forming assembly is preferably two, and the protrusions and grooves of the two forming bodies cooperate with each other to process the mat unit, and the mat unit can be processed by two roller-style forming bodies cooperating with each other to form Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by cooperating with two synchronous belt-style forming bodies. Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by cooperating with two press plate-style forming bodies. Figure 6 and Figure 7 The protrusions 11 and the depressions 12 are shown.

[0090] The number of the forming bodies in the forming assembly is preferably two, and the raised portions and the groove portions of the two forming bodies cooperate with each other to process the mat unit. A roller-shaped forming body and a synchronous belt-shaped forming body can cooperate with each other to process the mat unit to form Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by a roller-shaped forming body and a pressure plate-shaped forming body in cooperation with each other. Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown can also be formed by processing the mat unit by a synchronous belt style forming body and a pressure plate style forming body cooperating with each other to form Figure 6 and Figure 7 The protrusions 11 and the depressions 12 are shown.

[0091] A mat material forming machine comprises a machine body, a driving device and the aforementioned forming assembly, wherein the driving device and the forming assembly are both mounted on the machine body, and the driving device can drive the forming assembly to move to process the mat material unit, thereby forming Figure 6 and Figure 7 The protrusions 11 and the pits 12 shown in the figure; the paper material is pushed into the groove part of the other molded body by the protrusion on one molded body, thereby realizing the molding of the protrusions 11 and the pits 12 on the cushion material unit, thereby forming bubble paper. When the formed bubble paper is used to pack articles, it is highly likely that the two layers of bubble paper for packing the articles will not be completely overlapped, thereby ensuring the three-dimensional degree of the bubble paper after winding and improving the cushioning and shock-resistant effect on the articles.
