Description

Technical Field

[0001] This application relates to the technical field of buffer paper pad production, and in particular to a production device for buffer paper pads and a production process for buffer paper pads. Background Art

[0002] As a common packaging material, buffer paper pads are widely used in the buffer protection of various items. With the rapid development of the e-commerce and logistics industries, the demand for buffer paper pads is increasing day by day. The traditional production method of buffer paper pads mainly relies on manual operation. Although the manual method has certain advantages in terms of flexibility, its efficiency is low and it is difficult to meet the needs of large-scale production. At the same time, the stability of product quality is also difficult to guarantee, which puts higher requirements on the production of buffer paper pads.

[0003] To improve the production efficiency and quality stability of buffer paper pads, currently, the paper is usually preliminarily processed by a simple mechanical corrugating device, and the relative movement between the pressure rollers is used to achieve the deformation of the paper. Although the production efficiency is improved to a certain extent, there are still obvious deficiencies in terms of automation and product consistency, and this problem urgently needs to be improved. Summary of the Invention

[0004] In order to improve the production efficiency of buffer paper pads and at the same time improve the consistency of buffer paper pad production, this application provides a production device for buffer paper pads and a production process for buffer paper pads.

[0005] A production device for buffer paper pads and a production process for buffer paper pads provided by this application adopt the following technical solutions: A production device for buffer paper pads includes: A folding mechanism, the folding mechanism includes a conveying component, a folding component, and a folding and collecting component. The conveying component is used to convey the original paper coil. The folding component is arranged on the conveying path of the conveying component and is used to fold the two side edges of the original paper being conveyed inward. The folding and collecting component is arranged at the end of the conveying direction of the conveying component and is used to overlap and flip the folded original paper along the length direction of the original paper to form a bellows shape; An expanding and paper-feeding mechanism, the expanding and paper-feeding mechanism is used to expand the bellows-shaped original paper into a buffer paper pad. The expanding and paper-feeding mechanism includes a support frame, a paper-feeding module, an expanding module, and a gear module. The paper-feeding module is arranged at the head end of the support frame and is used to perform paper-feeding operation on the bellows-shaped original paper. The expanding module is arranged on the support frame and is located behind the paper-feeding module. The expanding module is used to expand the port of the bellows-shaped original paper. The gear module is arranged at the end of the support frame and is used to drive the original paper to move and perform rolling and paper-feeding operation.

[0006] By adopting the above technical solution, during the production process of the buffer paper cushion, the conveying component automatically conveys the original paper coil. During the conveying process of the original paper, the folding component folds the two side edges of the original paper inward in the conveying path to form a double-layer structure. Then, the folding and collecting component turns and folds the double-layer original paper along the length direction of the original paper at the end of the conveying path, so that the original paper forms an accordion-like structure. Then, the accordion-like original paper is transferred to the expanding paper outlet mechanism. The support frame supports the paper loading module, the expanding module, and the gear module. The paper loading module performs the paper loading operation on the accordion-like original paper. The expanding module expands and inflates the port of the accordion-like original paper, and realizes the expanding and inflation and paper outlet operations of the original paper under the rolling drive of the gear module, and finally forms a buffer paper cushion. The degree of automation is high, which is beneficial to improving the production efficiency of the buffer paper cushion and can improve the consistency of the production of the buffer paper cushion.

[0007] Preferably, the expanding module includes an expanding block, and the expanding block is hoisted on the support frame. One end of the expanding block facing the paper loading module is arranged as an arc-shaped slope. The width of the expanding block gradually decreases along the conveying direction of the original paper, and the thickness of the expanding block gradually increases along the conveying direction of the original paper.

[0008] By adopting the above technical solution, the port of the accordion-like original paper is sleeved into the expanding block to realize the change from the flat state to the expanding and inflation state. One end of the expanding block facing the paper loading module is arranged as an arc-shaped slope, which is convenient for gradually opening the port of the accordion-like original paper. And as the accordion-like original paper is conveyed in the expanding paper outlet mechanism, the width of the expanding block gradually decreases along the conveying direction of the original paper, and the thickness of the expanding block gradually increases along the conveying direction of the original paper, which is beneficial to improving the smoothness of the original paper from the flat state to the expanding state.

[0009] Preferably, the expanding module further includes a limiting frame, and the limiting frame is fixedly arranged on the support frame, and the limiting frame covers the expanding block. There is a passage for the original paper to pass between the limiting frame and the expanding block, and the cross-sectional area of the limiting frame gradually decreases along the conveying direction of the original paper.

[0010] By adopting the above technical solution, while the expanding block expands and inflates the original paper, the limiting frame limits the expanded original paper, which can prevent the original paper from completely spreading out and is beneficial to improving the consistency of the production of the buffer paper cushion.

[0011] Preferably, a U-shaped groove is opened at the end of the expanding block far from the paper loading module corresponding to the position where the side edge of the original paper is folded. The U-shaped groove is arranged in a closed-mouth shape, and a limiting plate is arranged along the length direction of the original paper at the middle position of the U-shaped groove.

[0012] By adopting the above technical solution, under the expanding action of the expanding block and the limiting action of the limiting frame, the base paper can be expanded and inflated. The U-shaped groove accommodates the two side edges of the base paper, and under the action of the limiting plate, it bends inward to form a curved surface, which is beneficial to improving the buffering effect of the buffer paper pad.

[0013] Preferably, the end and both sides of the expanding block facing the upper paper module are provided with rounded corners.

[0014] By adopting the above technical solution, during the process of the flat accordion-shaped base paper being sleeved on the expanding block, the folding position on the base paper slides across the edge position of the expanding block. This setting makes the base paper not easily scratched and damaged, thus being beneficial to improving the production quality of the buffer paper pad.

[0015] Preferably, the upper paper module includes a placement frame and a plurality of flattening rollers. The placement frame is arranged at the bottom of the support frame, and the plurality of flattening rollers are arranged on the support frame and are parallel to each other on one side of the expanding block. The accordion-shaped base paper is placed in the placement frame and is sleeved on the expanding block after passing around the plurality of flattening rollers.

[0016] By adopting the above technical solution, the accordion-shaped base paper is placed in the placement frame for feeding. The accordion-shaped base paper is sleeved on the expanding block after passing around a plurality of flattening rollers. While the flattening rollers guide the feeding of the base paper, during the process of the accordion-shaped base paper passing around the flattening rollers, the flattening rollers can flatten and straighten the folding position on the base paper, thus facilitating the subsequent expanding operation.

[0017] Preferably, the folding component includes a gantry, a support plate, a reversing plate, turning rods, limiting rollers, and pressing rollers. The gantry is arranged on the conveying path of the conveying component, the support plate is horizontally and fixedly arranged on the conveying component, the reversing plate is hoisted on the gantry, and the base paper being conveyed passes around the reversing plate and is horizontally conveyed onto the support plate. The number of the turning rods is set to two, and the two turning rods are symmetrically arranged on both sides of the reversing plate, and the upper ends of the two turning rods are inclined towards each other. The limiting roller is rotatably arranged above the support plate, and there is a gap for the base paper to pass between the limiting roller and the support plate. The number of the pressing rollers is set to two, and the two pressing rollers rotate towards each other, and the base paper passing through the limiting roller passes through the gap between the two pressing rollers.

[0018] By adopting the above technical solution, the gantry supports the support plate, the reversing plate, the flanging rod, the limiting roller and the pressing roller. The base paper is horizontally conveyed to the support plate after passing around the reversing plate. During the reversing process of the base paper, two symmetrically arranged flanging rods bend the two sides of the base paper inward, causing the two sides of the base paper to be folded inward. The limiting roller prevents the two side edges of the bent base paper from restoring, and then the pressing operation of the two pressing rollers is used to fold the two side edges of the base paper. The folding process is natural and smooth, with high folding quality, and the folding process is completed during the conveying process, which is beneficial to improving production efficiency.

[0019] Preferably, a plurality of the limiting rollers are provided, and the plurality of limiting rollers are respectively arranged on both sides of the support plate, and the limiting rollers are inclined relative to the pressing rollers.

[0020] By adopting the above technical solution, this setting conforms to the folding direction of the two side edges of the base paper, which is beneficial to improving the folding quality.

[0021] Preferably, the folding and folding mechanism further includes a edge-locking assembly, the edge-locking assembly is arranged on the conveying path of the conveying assembly, the edge-locking assembly includes two edge-locking rollers arranged in parallel and rotating towards each other, and there is a gap for the base paper to pass through between the two edge-locking rollers. An edge-locking block is arranged on the surface of one edge-locking roller, and an edge-locking groove is correspondingly formed on the surface of the other edge-locking roller, and the edge-locking block is fitted with the edge-locking groove.

[0022] By adopting the above technical solution, when the folded base paper or multiple layers of base paper pass through the gap between the two edge-locking rollers, the edge-locking block on one edge-locking roller is embedded into the edge-locking groove on the other edge-locking roller, and the edge-locking roller presses the part of the folded base paper or multiple layers of base paper at the embedding position into the edge-locking groove. Without damaging the base paper, it is beneficial to improve the connection firmness of the folded base paper or multiple layers of base paper, and it is not easy to loosen during subsequent operations, thus being beneficial to improving the quality of subsequent operations.

[0023] A production process of a buffer paper pad includes using the above-mentioned production device for buffer paper pads, and includes the following steps: S1: Feeding and conveying of the base paper coil, and the conveying assembly conveys the base paper; S2: Paper stacking and edge-locking. When producing multi-layer buffer paper pads, multiple base papers are stacked during conveying, and then the multiple base papers are edge-locked and fixed by the edge-locking assembly; S3: Folding of the base paper. During the conveying process of the base paper on the conveying assembly, the folding assembly folds the two side edges of the conveying base paper inward; S4: Folding of the base paper. When the folded base paper is conveyed to the end of the conveying assembly, the folding and collecting assembly overlaps and flips the folded base paper along the length direction of the base paper to form a bellows shape for collection; S5: Inflation forming. The accordion-shaped base paper is wound from the placement frame, passes through the flattening roller, and then is sleeved on the expanding block for expansion. The paper is discharged by rolling through the gear module, and finally a buffer paper pad is formed.

[0024] By adopting the above technical solution, when producing a buffer paper pad, the conveying component discharges and conveys the base paper coil. When producing multiple layers of buffer paper pads, the edge-locking component stacks and fixes multiple layers of base paper, which is beneficial to improving the connection stability of multiple layers of base paper. As the conveying component continues to convey the base paper, the folding component folds the two side edges of the base paper inward and performs an overlapping folding operation in the length direction on the folded base paper at the end of the conveying component to form an accordion-shaped base paper. Subsequently, the accordion-shaped base paper is transferred to the inflation and paper discharging mechanism. The accordion-shaped base paper is wound from the placement frame, passes through the flattening roller, and then is sleeved on the expanding block for expansion. The paper is discharged by rolling through the gear module, and finally a buffer paper pad is formed. The degree of automation is high, which is beneficial to improving the production efficiency of the buffer paper pad and can improve the consistency of the production of the buffer paper pad.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a conveying component, a folding component, a folding and collecting component, a paper feeding module, an expanding module, and a gear module, during the production process of the buffer paper pad, the conveying component automatically conveys the base paper coil. During the conveying process of the base paper, the folding component folds the two side edges of the base paper inward in the conveying path to form a double-layer structure. Then, the folding and collecting component turns and folds the folded base paper with a double-layer structure along the length direction of the base paper at the end of the conveying path, so that the base paper forms an accordion-shaped structure. Then, the accordion-shaped base paper is transferred to the inflation and paper discharging mechanism. The support frame supports the paper feeding module, the expanding module, and the gear module. The paper feeding module performs paper feeding operation on the accordion-shaped base paper. The expanding module expands and inflates the port of the accordion-shaped base paper, and under the rolling drive of the gear module, the expansion and inflation of the base paper and the paper discharging operation are realized, and finally a buffer paper pad is formed. The degree of automation is high, which is beneficial to improving the production efficiency of the buffer paper pad and can improve the consistency of the production of the buffer paper pad.

[0026] 2. By setting an expanding block, the port of the accordion-shaped base paper is sleeved on the expanding block to realize the change from a flat state to an expanded and inflated state. The end of the expanding block facing the paper feeding module is provided with an arc-shaped slope to facilitate gradually opening the port of the accordion-shaped base paper. And as the accordion-shaped base paper is conveyed in the inflation and paper discharging mechanism, the width of the expanding block gradually decreases along the conveying direction of the base paper, and the thickness of the expanding block gradually increases along the conveying direction of the base paper, which is beneficial to improving the smoothness of the base paper from a flat state to an inflated state.

[0027] 3. By opening a U-shaped groove on the expanding block, the U-shaped groove is arranged in a closed-mouth shape, and a limiting plate is arranged in the U-shaped groove. Under the expanding action of the expanding block and the limiting action of the limiting frame, the base paper can expand and bulge. The U-shaped groove accommodates the two side edges of the base paper, and bends inward to form a curved surface under the action of the limiting plate, which is beneficial to improving the buffering effect of the buffer paper pad.

[0039] The following is combined with Figures 1 - 10 This application is described in further detail.

[0040] The present application embodiment discloses a production device for a cushioning paper pad, referring to Figure 1 , including a folding mechanism 1 and an expanding paper discharging mechanism 2. The folding mechanism 1 makes the base paper roll into an accordion shape and collects it, and the expanding paper discharging mechanism 2 expands the accordion-shaped base paper to finally form a buffer paper pad. The entire production process has a high degree of automation, which is beneficial to improving the production efficiency of the buffer paper pad and can improve the consistency of the buffer paper pad production.

[0041] Reference Figure 1 and Figure 2 The folding mechanism 1 includes a conveying component 11, a folding component 12 and a folding and receiving component 13. The conveying component 11 is used to convey the base paper coil. The folding component 12 is arranged on the conveying path of the conveying component 11 and is used to fold the two side edges of the conveyed base paper inward. The folding and receiving component 13 is arranged at the end of the conveying direction of the conveying component 11 and is used to overlap, flip and fold the folded base paper along the length direction of the base paper to form an accordion shape. The accordion-shaped base paper reduces space occupied and is convenient for subsequent expansion operations.

[0042] Reference Figure 2 and Figure 3 The conveying assembly 11 includes a conveying frame 111 and a plurality of rotating conveying rollers 112, and the plurality of conveying rollers 112 are arranged in parallel, and the rotating conveying rollers 112 drive the base paper to be conveyed backward. During the conveying process of the base paper, the folding assembly 12 operates the two sides of the base paper, and then refers to Figure 4, the folding component 12 includes a gantry 121, a support plate 122, a reversing plate 123, flanging rods 124, limiting rollers 125 and pressing rollers 126. The gantry 121 is located on the conveying path of the conveying component 11 and fixed to the conveying frame 111. The support plate 122 is horizontally and fixedly arranged on the conveying frame 111. The reversing plate 123 is hoisted on the gantry 121. The original paper being conveyed is horizontally conveyed to the support plate 122 after passing around the reversing plate 123, and the support plate 122 horizontally supports the conveyance of the original paper. The number of flanging rods 124 is set to two. The two flanging rods 124 are symmetrically and fixedly arranged on the conveying frame 111 and located on both sides of the reversing plate 123. The upper ends of the two flanging rods 124 incline towards each other. When the two side edges of the original paper pass through the position between the reversing plate 123 and the flanging rods 124, the flanging rods 124 turn up the side edges of the original paper. The limiting rollers 125 are horizontally rotatably arranged above the support plate 122. There is a gap for the original paper to pass through between the limiting rollers 125 and the support plate 122. Under the limiting action of the support plate 122 and the limiting rollers 125, the side edges of the original paper turn up for folding and form a double-layer structure with the middle part of the original paper. The number of pressing rollers 126 is set to two. The two pressing rollers 126 rotate towards each other. The original paper passing through the limiting rollers 125 passes through the gap between the two pressing rollers 126 to press the side edges of the folded original paper against the middle part of the original paper so that it is difficult to recover.

[0043] It should be noted that the number of limiting rollers 125 is set to several. The several limiting rollers 125 are distributed on both sides of the support plate 122, and the limiting rollers 125 are inclined relative to the pressing rollers 126 to conform to the folding direction of the two side edges of the original paper, thus being beneficial to improving the folding quality.

[0044] Refer to Figure 2 and Figure 5 , when it is necessary to produce a buffer paper pad from multiple layers of original paper, the multiple layers of original paper need to be stacked and fixed before the folding operation. Therefore, the folding and folding mechanism 1 further includes a side-locking component 14. The side-locking component 14 is arranged on the conveying path of the conveying component 11. Specifically, the side-locking component 14 includes two side-locking rollers 141 that are parallel and rotate towards each other. There is a gap for the multiple layers of original paper to pass through between the two side-locking rollers 141. A side-locking block 5 is arranged on the surface of one side-locking roller 141, and a side-locking groove 6 is correspondingly formed on the surface of the other side-locking roller 141. The side-locking block 5 is fitted with the side-locking groove 6. When the multiple layers of original paper pass through the gap between the two side-locking rollers 141, the side-locking block 5 presses the multiple layers of original paper into the side-locking groove 6, improving the connection firmness of the multiple layers of original paper without damaging the original paper, and the subsequent folding operation is not easy to become loose. It should be noted that the shapes of the side-locking block 5 and the side-locking groove 6 can be polygonal, circular, etc., which are not limited here.

[0045] Refer to Figure 2 and Figure 6, the folding and material collecting component 13 forms a bellows-shaped base paper through the cooperation of the left and right swinging clamping plates and the push rod with the conveyance of the base paper. This is a conventional setting for overlapping and flipping folding, which will not be elaborated here.

[0046] Refer to Figure 7 , after the collection of the bellows-shaped base paper is completed, the expanding paper discharging mechanism 2 expands the bellows-shaped base paper to form a buffer paper pad product. Specifically, the expanding paper discharging mechanism 2 includes a support frame 21, a paper loading module 22, an expanding module 23, and a gear module 24. The support frame 21 supports the paper loading module 22, the expanding module 23, and the gear module 24. The paper loading module 22 is arranged at the front end of the support frame 21 for loading the bellows-shaped base paper. The expanding module 23 is arranged on the support frame 21 and behind the paper loading module 22. The expanding module 23 is used to expand the port of the bellows-shaped base paper. The gear module 24 is arranged at the end of the support frame 21 for driving the movement of the base paper and performing the rolling and paper discharging operation.

[0047] Refer to Figure 7 and Figure 8 , the paper loading module 22 includes a placing frame 221 and a plurality of flattening rollers 222. The placing frame 221 is fixedly arranged at the bottom of the support frame 21 for placing the bellows-shaped base paper. The plurality of flattening rollers 222 are arranged on the support frame 21 and on one side of the expanding module 23 in parallel. The bellows-shaped base paper is placed in the placing frame 221 and enters the expanding module 23 after passing around the plurality of flattening rollers 222. While the flattening rollers 222 guide the paper loading, during the process that the bellows-shaped base paper passes around the flattening rollers 222, the flattening rollers 222 can flatten and straighten the folding positions on the base paper, so as to facilitate the subsequent expanding operation.

[0048] Refer to Figure 8 and Figure 9 , the expanding module 23 includes an expanding block 231. The expanding block 231 is hoisted on the support frame 21. One end of the expanding block 231 facing the paper loading module 22 is arranged as an arc-shaped slope. The port of the bellows-shaped base paper is sleeved on the expanding block 231 to realize the change from the flat state to the expanded state. At the same time, the width of the expanding block 231 gradually decreases along the conveyance direction of the base paper, and the thickness of the expanding block 231 gradually increases along the conveyance direction of the base paper. With the conveyance of the bellows-shaped base paper in the expanding paper discharging mechanism 2, it is beneficial to improve the smoothness of the base paper from the flat state to the expanded state. It is worth mentioning that the end and both sides of the expanding block 231 facing the paper loading module 22 are arranged as rounded corners to prevent the base paper from being scratched during the process of being sleeved on the expanding block 231, thereby reducing the production quality of the buffer paper pad.

[0049] Refer to Figure 8, the expanding module 23 further includes a limiting frame 232 which is fixedly arranged on the support frame 21 and covers the expanding block 231. There is a passage for the base paper to pass between the limiting frame 232 and the expanding block 231, and the cross-sectional area of the limiting frame 232 gradually decreases along the conveying direction of the base paper to adapt to the shape of the expanding block 231. While the expanding block 231 expands the base paper, the limiting frame 232 limits the expanded base paper to prevent the base paper from completely spreading out.

[0050] Refer to Figure 8 and Figure 9 , a U-shaped groove 3 is formed at the end of the expanding block 231 away from the paper feeding module 22 corresponding to the position where the side of the base paper is folded. The U-shaped groove 3 is arranged in a closed-mouth shape. Refer to Figure 10 , a limiting plate 4 is arranged along the length direction of the base paper at the middle position of the U-shaped groove 3. During the process of expanding the base paper, the U-shaped groove 3 accommodates the two sides of the base paper, and under the action of the limiting plate 4, it bends inward to form a curved surface, thereby improving the buffering effect of the buffer paper pad.

[0051] Refer to Figure 8 , the gear module 24 includes two gears driven by a motor to rotate towards each other and mesh with each other, and there is a gap for the middle position of the base paper to pass through between the two gears. When the expanded base paper passes through between the two gears, the two gears rotating towards each other roll the middle position of the base paper, and while driving the conveyance of the base paper, the middle position of the base paper is wrinkled, thereby forming the buffer paper pad.

[0052] The embodiment of the present application also discloses a production process of a buffer paper pad, including using the above production device, and includes the following steps: S1: The base paper roll is discharged and conveyed, and the conveying component 11 conveys the base paper; S2: Paper stacking and edge locking. When multiple layers of buffer paper pads need to be produced, multiple base papers are stacked during conveyance, and then the multiple base papers are edge-locked and fixed by the edge-locking component 14 to prevent the multiple base papers from becoming loose during subsequent folding and turning operations; S3: Base paper folding. During the conveyance of the base paper on the conveying component 11, the base paper is horizontally conveyed to the support plate 122 after passing around the reversing plate 123. The two turning rods 124 turn up the two sides of the base paper at the reversing position, and under the pressing action of the limiting roller 125 and the pressing roller 126, a double-layer structure with the two sides folded inward is formed; S4: Base paper turning. When the folded base paper is conveyed to the end of the conveying component 11, the folding and collecting component 13 overlaps and turns the folded base paper along the length direction of the base paper to form a bellows shape for collection; S5: Inflation molding. The accordion-shaped base paper is wound from the placement frame 221 around the flattening roller 222 and then sleeved on the expansion block 231 for expansion, and the paper feeding operation is carried out by rolling through the gear module 24, and finally a buffer paper pad is formed. The whole production process of the buffer paper pad has a high degree of automation, which is beneficial to improving the production efficiency of the buffer paper pad and can improve the consistency of the production of the buffer paper pad.

[0053] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
