Description

Technical Field

[0001] The utility model relates to the field of three-dimensional paper pad manufacturing for cushioning and packaging articles, in particular to a wide-width paper guiding deformation mechanism for connecting a paper pad machine. Background Art

[0002] In logistics transportation, items will be cushioned and packaged, and cushioning materials will be placed in packaging boxes or packaging bags. Pillow-shaped three-dimensional paper pads are one of them. Pillow-shaped three-dimensional paper pads are produced by paper pad forming machines (referred to as "paper pad machines"). The paper pad machine mainly includes three main structures: feeding, forming, and discharging. Among them, the feeding structure part will guide the paper material to form a certain three-dimensional shape, the forming structure part (two forming gears arranged up and down) will pull the paper material to move in the paper pad machine, and at the same time shape the three-dimensional paper material, and the discharging structure will transport the shaped three-dimensional paper pad out. The feeding structure part is provided with a flow channel structure, and the flow channel structure includes an outer flow channel and an inner flow channel. After the paper material is fed, it will enter between the outer flow channel and the inner flow channel. The outer flow channel and the inner flow channel will guide the paper material to form a certain three-dimensional shape, and then transport it to the forming structure part for processing. After the processing is completed, the three-dimensional paper pad is discharged from the discharging end of the discharging structure.

[0003] Since the pillow-shaped three-dimensional paper pad finally presents a double-layered wrinkled three-dimensional structure, part of its raw materials are single-layer paper materials with a larger width (referred to as "wide-width paper"), and the wide-width paper is guided by a paper pad machine to form a buffering three-dimensional structure with a smaller width and a certain thickness. Since the raw material itself is relatively wide, this paper pad machine equipment that directly processes wide-width paper has a larger volume; part of its raw materials are pre-folded paper structures, that is, the raw material is a middle surface and folding surfaces located on both sides of the middle surface, and the two folding surfaces are folded toward the middle surface, and the edges of the two folding surfaces are spaced, aligned exactly, or have overlapping areas, so that the width of the raw material is greatly reduced, thereby reducing the volume of the guiding deformation structure of the paper pad machine equipment, and this paper pad machine equipment that directly processes pre-folded paper with a smaller width has a smaller volume.

[0004] At present, due to the different raw materials, including single-layer wide-width paper and pre-folded paper, there are paper padding machines targeted at wide-width paper and paper padding machines targeted at pre-folded paper. These two types of paper padding machines cannot be mixed. Users cannot choose different types of paper materials for production and processing according to the cost and demand of raw materials. The applicability is weak and lacks flexibility.

[0005] In addition, when the existing paper padding machine processes wide-width paper or pre-folded paper, the wide-width paper or pre-folded paper is usually stacked in the upstream direction of the paper inlet of the paper padding machine, and this placement method will occupy a large site area. Utility Model Content

[0006] The utility model aims to provide a wide-width paper guiding and deforming mechanism to solve at least one of the above-mentioned technical problems.

[0007] According to one aspect of the utility model, a wide paper guiding and deforming mechanism of a paper padding machine is provided, comprising:

[0008] An outer channel, both sides of the outer channel are folded or bent toward the middle to drive the two sides of the wide paper to be folded or bent toward the middle of the wide paper, and the two sides of the outer channel are gathered in a direction from the paper inlet to the paper outlet of the outer channel;

[0009] An inner channel component, the inner channel component is arranged in the outer channel;

[0010] A guide roller, which is arranged at the paper inlet of the outer channel; and

[0011] The bottom roller is arranged at the paper inlet of the outer channel, and is located between the guide roller and the inner channel component. The top of the guide roller is higher than the bottom of the bottom roller, and the bottom of the inner channel component is lower than the bottom of the bottom roller.

[0012] The wide-width paper guiding and deforming mechanism of the utility model can be installed on the paper pad machine, and the paper outlet of the outer channel is butted with the material inlet of the paper pad machine, so that the bottom of the paper outlet of the outer channel can be slightly higher than the bottom of the material inlet of the paper pad machine and the width of the paper outlet of the outer channel is greater than the width of the material inlet of the paper pad machine to ensure that the paper material will not be stuck at the junction of the two; when the raw material (i.e., paper material) is wide-width paper, the wide-width paper is fed into between the inner channel component and the outer channel through the paper inlet of the outer channel, and specifically the starting end of the wide-width paper is passed around the upper edge of the guide roller The paper moves from the paper inlet of the outer channel to the paper outlet under the traction of the paper pad machine. Since the two sides of the outer channel are folded or bent toward the middle and are gathered from the paper inlet to the paper outlet, under the action of the outer channel, the two sides of the wide paper will be folded or bent toward the middle of the wide paper to form a three-dimensional paper with a smaller width, so as to provide the paper pad machine for the next step of processing and forming. In addition, the inner channel component can press down the middle of the wide paper to limit it, preventing the wide paper from During the deformation process, the middle part thereof arches upward, affecting the forming effect. Since the top of the guide roller is higher than the bottom of the bottom roller and the bottom of the inner channel component is lower than the bottom of the bottom roller, the bottom roller and the end of the inner channel component close to the paper inlet of the outer channel will pre-bend the two side edges of the wide-width paper to a certain extent, so that the subsequent deformation of the two side edges of the wide-width paper in the outer channel will be smoother; when the raw material (i.e., paper material) is pre-folded paper, the inner channel component can be removed, or the wide-width paper guiding and deforming mechanism can be directly removed, and the paper padding machine can directly process and shape the pre-folded paper. The wide-width paper guiding and deforming mechanism of the utility model can be used as a supplementary structure of the current paper padding machine that directly processes pre-folded paper. According to needs, the paper padding machine can directly process and shape the pre-folded paper, or it can be connected to the wide-width paper guiding and deforming mechanism to process and shape the wide-width paper that is not pre-folded, thereby increasing the applicability of the existing paper padding machine, so that the existing paper padding machine can meet the needs of two types of paper materials (wide-width paper and pre-folded paper), can adapt to the processing needs of different paper materials, and does not affect the volume of the paper padding machine body.

[0013] In some embodiments, the spacing between the bottom of the inner channel component and the inner bottom of the outer channel can be 5 to 50 mm. Thus, the spacing of 5 to 50 mm can ensure that the paper material will not be stuck between the bottom of the inner channel component and the inner bottom of the outer channel, and can effectively prevent the middle of the wide paper from bulging upward during the deformation process to affect the forming effect. The spacing of 5 to 50 mm can ensure the quality of the three-dimensional paper material formed by the paper material.

[0014] In some embodiments, arc-shaped guide blocks may be respectively disposed at two corners of the end of the inner channel component close to the paper inlet of the outer channel, so that the arc-shaped guide blocks can prevent the two corners of the end of the inner channel component from cutting the paper material.

[0015] In some embodiments, an outer channel may be provided with an outward-turned portion near the paper feed port, and the outward-turned portion is arranged at an obtuse angle with the outer bottom of the outer channel. Thus, during the paper feeding process, the paper will jump and be easily cut by the edge of the outer channel. The provision of the outward-turned portion can prevent the paper from being cut when it enters between the outer channel and the inner channel components, and at the same time facilitates the smoothness of paper feeding. The outward-turned portion is arranged at an obtuse angle with the outer bottom of the outer channel to ensure that the paper will not be cut by the edge of the outer channel when feeding.

[0016] In some embodiments, the end of the inner channel component close to the paper inlet of the outer channel may be in a bevel shape, and the plane where the end of the inner channel component close to the paper inlet of the outer channel is located is arranged at an obtuse angle with the bottom of the inner channel component. Thus, the design of the end of the inner channel component in a bevel shape can ensure that the paper will not be cut by the end of the inner channel component when entering the bottom of the inner channel component, and the plane where the end of the inner channel component is located is arranged at an obtuse angle with the bottom of the inner channel component to ensure that the paper smoothly enters the bottom of the inner channel component, thereby ensuring the smoothness of paper feeding.

[0017] In some embodiments, both ends of the bottom roller may be conical, so that the conical ends of the bottom roller can pre-bend the two sides of the wide paper, so that the subsequent deformation of the two sides of the wide paper in the outer channel becomes smoother.

[0018] In some embodiments, flanges may be provided on both sides of the inner channel component, so that the two sides of the inner channel component can play a good role in supporting, limiting and guiding the paper material to be folded or bent toward the middle, and at the same time, the flanges on both sides of the inner channel component can ensure that the paper material will not be cut by the two sides of the inner channel component when it is quickly transported between the inner channel component and the outer channel.

[0019] In some embodiments, the inner channel component is detachably connected to the outer channel. Therefore, when the raw material is pre-folded paper, the inner channel component can be removed from the outer channel, so that the paper pad machine can directly process and shape the pre-folded paper, which is very convenient when switching between wide paper and pre-folded paper.

[0020] In some embodiments, the width of the inner channel component can be gradually reduced from the paper inlet to the paper outlet, so that the inner channel component and the outer channel sides have the same convergence trend, ensuring that the two sides of the wide paper can be smoothly folded or bent toward the middle.

[0021] In some embodiments, a gantry-shaped support structure may be further included, and the bottom of the outer channel is arranged on the gantry-shaped support structure. Thus, after the wide-width paper guiding and deforming mechanism is connected to the paper pad machine, the raw materials can be stacked in the gantry-shaped support structure, thereby greatly reducing the floor space occupied by the raw materials.

[0022] In some embodiments, a mounting plate may be provided on the top of the gantry-shaped support structure, the bottom of the outer channel is provided on the top of the mounting plate, and the side of the mounting plate is used to mount and fix the head part of the paper pad machine.

[0023] When the head part of the paper pad machine is installed on the side of the mounting plate, the bottom of the inner channel component is lower than the bottom of the inner flow channel in the paper pad machine and lower than the center plane between two upper and lower forming gears in the paper pad machine.

[0024] Thus, the outer channel can be mounted and fixed on the gantry-shaped support structure through the mounting plate, and the paper pad machine can also be mounted and fixed on the gantry-shaped support structure. At the same time, the head part of the paper pad machine can be fixed on the side of the mounting plate to improve the stability of the paper pad machine during operation. In addition, when the head part of the paper pad machine is mounted on the side of the mounting plate, the height setting among the bottom of the inner channel component, the bottom of the inner flow channel in the paper pad machine, and the center plane between two upper and lower arranged forming gears in the paper pad machine can make the inner channel component always maintain a tendency to press down the middle part of the wide paper to limit it, thereby ensuring the forming effect of the three-dimensional paper material entering the paper pad machine.

[0025] In some embodiments, the gantry-shaped support structure may include a first gantry-shaped support and a second gantry-shaped support arranged in parallel, the bottom of the outer channel is arranged on the first gantry-shaped support, and the second gantry-shaped support can be mounted and fixed with a paper padding machine. Thus, after the wide-paper guiding and deforming mechanism is connected to the paper padding machine, the raw materials can be stacked in the first gantry-shaped support and the second gantry-shaped support, which greatly reduces the floor space occupied by the raw materials, and the first gantry-shaped support can provide a load for the outer channel, and the second gantry-shaped support can provide a load for the paper padding machine.

[0026] In some embodiments, the top of the second gantry-shaped support can be lower than the top of the first gantry-shaped support. Thus, it is convenient to make the bottom of the paper outlet of the outer channel slightly higher than the bottom of the inlet of the paper pad machine to ensure that the paper material will not be stuck at the junction of the two.

[0027] In some embodiments, a support frame may be further included, on which the gantry-shaped support structure is arranged, and casters are arranged at the bottom of the support frame. Thus, the gantry-shaped support structure can stand steadily through the support frame, and the casters at the bottom of the support frame facilitate the movement of the whole.

[0028] In some embodiments, the gantry-shaped support structure may be provided with a guide rod, so that the raw materials in the gantry-shaped support structure can smoothly enter between the inner channel component and the outer channel through the guide rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Embodiment 1:

[0042] Figures 1 to 7 The structure of a wide-paper guiding and deforming mechanism according to an embodiment of the utility model is schematically shown.

[0043] refer to Figures 1 to 7 The wide-width paper guiding and deforming mechanism comprises an outer channel 1, an inner channel component 2, a guide roller 3 and a bottom roller 4.

[0044] refer to Figures 1 to 3 , the two sides of the outer channel 1 are folded or bent toward the middle, so that the outer channel 1 can drive the two sides of the wide paper to fold or bend toward the middle of the wide paper; specifically, refer to Figure 1 and Figure 2 The outer channel 1 includes a left side plate 101, a right side plate 102 and a bottom plate 103. The left side plate 101 and the right side plate 102 are respectively arranged on both sides of the bottom plate 103 and can be integrally formed. The left side plate 101 and the right side plate 102 are both curved. In addition, the outer channel 1 is in a contracted shape from the paper inlet 100 to the paper outlet 200. Specifically: Figure 2 The width of the bottom plate 103 is from the paper inlet 100 to the paper outlet 200 ( Figure 1 As shown in the figure, the outer channel 1 gradually decreases in the horizontal direction from the paper inlet 100 to the paper outlet 200, and at the same time, the reference Figure 4 , the left side plate 101 and the right side plate 102 extend from the paper inlet 100 to the paper outlet 200 ( Figure 1 When the wide paper moves from the paper inlet 100 to the paper outlet 200 of the outer channel 1, the two sides of the wide paper will be folded or bent toward the middle of the wide paper to form a three-dimensional paper material with a smaller width.

[0045] refer to Figures 1 to 3The inner channel component 2 is installed in the outer channel 1, and the width of the inner channel component 2 gradually decreases from the paper inlet 100 to the paper outlet 200 of the outer channel 1. Gaps are left between the left plate 101 and the right plate 102 on both sides of the inner channel component 2 for paper to pass through. When the raw material (i.e., paper) is wide paper, the wide paper is fed into between the inner channel component 2 and the outer channel 1 through the paper inlet 100 of the outer channel 1. The middle part of the wide paper is located at the bottom of the inner channel component 2. The inner channel component 2 can press down the middle part of the wide paper to limit it, so as to prevent the middle part of the wide paper from arching upward during the deformation process to affect the forming effect, and ensure that the wide paper is smoothly deformed in the outer channel 1.

[0046] refer to Figure 4 In this embodiment, the spacing H between the bottom of the inner channel component 2 and the inner bottom of the outer channel 1 is 5 to 50 mm. The spacing of 5 to 50 mm can not only ensure that the paper will not be stuck between the bottom of the inner channel component 2 and the inner bottom of the outer channel 1, but also effectively prevent the middle of the wide paper from arching upward during the deformation process to affect the forming effect. The spacing of 5 to 50 mm can ensure the quality of the three-dimensional paper formed by the paper.

[0047] refer to Figure 5 The end of the inner channel component 2 close to the paper feed port of the outer channel 1 is in a bevel shape, and the plane 202 where the end of the inner channel component 2 close to the paper feed port of the outer channel 1 is located is arranged at an obtuse angle to the bottom 201 of the inner channel component 2. The beveled design of the end of the inner channel component 2 can ensure that the paper will not be cut by the end of the inner channel component 2 when entering the bottom of the inner channel component 2. The plane 202 where the end of the inner channel component 2 is located is arranged at an obtuse angle to the bottom 201 of the inner channel component 2 to ensure that the paper smoothly enters the bottom of the inner channel component 2, thereby ensuring the smoothness of paper feeding.

[0048] refer to Figure 1 and Figure 3 The inner channel component 2 has flanges 203 extending upwards formed on both sides. The two sides of the inner channel component 2 can provide good support, limit and guide for the paper to be folded or bent toward the middle. At the same time, the flanges 203 on both sides of the inner channel component 2 can ensure that the paper will not be cut by the two sides of the inner channel component 2 when it is quickly transported between the inner channel component 2 and the outer channel 1. The flanges 203 can be flat or curved.

[0049] The inner channel component 2 is detachably connected to the outer channel 1. Specifically, refer to Figures 1 to 3Two vertical connecting rods 23 are installed on the inner channel component 2, and a horizontal fixing plate 22 is installed on the top of the two connecting rods 23. The two ends of the fixing plate 22 can be respectively fixed on the left plate 101 and the right plate 102 by screws. The inner channel component 2 is in a suspended state in the outer channel 1. When the raw material is pre-folded paper, the inner channel component 2, the connecting rods 23, and the fixing plate 22 can be removed from the outer channel 1 as a whole, so that the paper pad machine can directly process and shape the pre-folded paper, which is very convenient when switching between wide paper and pre-folded paper.

[0050] refer to Figure 2 and Figure 3 Arc guide blocks 21 are respectively installed at the two corners of the end of the inner channel component 2 close to the paper feed port of the outer channel 1. The two arc guide blocks 21 are respectively located at the two corners of the end of the inner channel component 2. The two arc guide blocks 21 on the inner channel component 2 can prevent the two corners of the end of the inner channel component 2 from cutting the paper. The arc guide blocks 21 can also be formed integrally with the end of the inner channel component 2.

[0051] In this embodiment, the inner channel component 2 is plate-shaped as a whole. In other embodiments, the inner channel component 2 can also be frame-shaped as a whole as needed, as long as the end portion close to the paper inlet of the outer channel 1, the arc-shaped guide block 21, and the flanges 203 on both sides are arranged so that the overall width gradually decreases from the paper inlet to the paper outlet of the outer channel 1.

[0052] refer to Figure 3 , Figures 5 to 7 An outward turning portion 11 is formed near the paper inlet 100 of the outer channel 1. The outward turning portion 11 is formed by folding the end of the bottom plate 103 of the outer channel 1 near the paper inlet 100 downward at a certain angle. The outward turning portion 11 is arranged at an obtuse angle to the outer bottom of the outer channel 1, that is, the bottom plate 103. The outward turning portion 11 can prevent the paper from being cut when it enters between the outer channel 1 and the inner channel component 2, and at the same time facilitates the smoothness of paper feeding. The outward turning portion 11 is arranged at an obtuse angle to the outer bottom of the outer channel 1 to ensure that the paper will not be cut by the edge of the outer channel 1 when feeding.

[0053] The guide roller 3 is installed at the paper inlet of the outer channel 1. Specifically, refer to Figures 1 to 3 One end of the guide roller 3 is installed on the left extension plate 1011 of the left plate 101, and the other end of the guide roller 3 is installed on the right extension plate 1021 on the right plate 102. When subjected to external force, the guide roller 3 can be set to rotate between the left extension plate 1011 and the right extension plate 1021, or it can be set not to rotate.

[0054] The bottom roller 4 is installed at the paper inlet of the outer channel 1. Specifically, refer to Figures 1 to 3One end of the bottom roller 4 is installed on the left extension plate 1011 of the left plate 101, and the other end of the bottom roller 4 is installed on the right extension plate 1021 on the right plate 102. When subjected to external force, the bottom roller 4 can be set to rotate between the left extension plate 1011 and the right extension plate 1021, or it can be set not to rotate.

[0055] refer to Figure 1 and Figure 2 The bottom roller 4 is located between the guide roller 3 and the inner channel component 2, the guide roller 3 is located obliquely above the bottom roller 4, and both ends of the bottom roller 4 are conical. Figure 4 , the top of the guide roller 3 is higher than the bottom of the bottom roller 4, and the bottom of the inner channel component 2 is lower than the bottom of the bottom roller 4. When the raw material (i.e., paper) is wide paper, the starting end of the wide paper is passed over the top of the guide roller 3 and enters the bottom of the inner channel component 1 from the bottom of the bottom roller 4. Under the traction of the paper pad machine, the paper moves from the paper inlet 100 of the outer channel 1 to the paper outlet 200. Under the action of the outer channel 1, the two sides of the wide paper will be folded or bent toward the middle of the wide paper to form a three-dimensional paper with a smaller width. Since the top of the guide roller 3 is higher than the bottom of the bottom roller 4, the bottom of the inner channel component 2 is lower than the bottom of the bottom roller 4, and the two ends of the bottom roller 4 are conical, the two ends of the bottom roller 4 and the end of the inner channel component 2 close to the paper inlet 100 of the outer channel 1 will pre-bend the two sides of the wide paper, so that the subsequent deformation of the two sides of the wide paper in the outer channel 1 will be smooth.

[0056] refer to Figures 1 to 7The wide paper guiding deformation mechanism of the utility model can be installed on the paper pad machine, and the paper outlet 200 of the outer channel 1 is connected with the inlet of the paper pad machine, so that the bottom of the paper outlet 200 of the outer channel 1 is slightly higher than the bottom of the inlet of the paper pad machine and the width of the paper outlet 200 of the outer channel 1 is greater than the width of the inlet of the paper pad machine to ensure that the paper material will not be stuck at the junction of the two. At the same time, ensure that the bottom of the inner channel component 2 is lower than the bottom of the inner flow channel in the paper pad machine and lower than the center plane between the two forming gears arranged up and down in the paper pad machine; when the raw material (i.e., paper material) is wide paper, the starting end of the wide paper is passed over the top of the guide roller 3 and enters from the bottom of the bottom roller 4. At the bottom of the inner channel component 2, under the traction of two forming gears arranged up and down in the paper pad machine, the paper moves from the paper inlet 100 of the outer channel 1 to the paper outlet 200. Since the outer channel 1 is gradually contracted in the horizontal and vertical directions from the paper inlet 100 to the paper outlet 200, under the action of the outer channel 1, the two sides of the wide paper will be folded or bent toward the middle of the wide paper to form a three-dimensional paper with a smaller width, so that the paper pad machine can carry out the next step of processing and forming. Since the top of the guide roller 3 is higher than the bottom of the bottom roller 4, the bottom of the inner channel component 2 is lower than the bottom of the bottom roller 4, and the two ends of the bottom roller 4 are conical, the two ends of the bottom roller 4 and the inner channel component 2 are close to each other. The end of the paper inlet 100 of the outer channel 1 will pre-bend the two sides of the wide paper, so that the subsequent deformation of the two sides of the wide paper in the outer channel 1 will be smooth, and the two arc-shaped guide blocks 21 on the inner channel component 2 can prevent the two corners of the inner channel component 2 from cutting the paper. The flanges 203 on both sides of the inner channel component 2 can ensure that the paper will not be cut by the two sides of the inner channel component 2 when it is quickly transported between the inner channel component 2 and the outer channel 1. The design of the inclined end of the inner channel component 2 and the outward turning part 11 on the outer channel 1 can ensure that the paper smoothly enters the bottom of the inner channel component 2, ensuring the smoothness of paper feeding; when the raw material (i.e., paper) is When pre-folding paper, the inner channel component 2 can be removed, or the wide-width paper guiding and deforming mechanism can be directly removed, and the paper padding machine can directly process and shape the pre-folded paper. The wide-width paper guiding and deforming mechanism of the utility model can be used as a supplementary structure of the current paper padding machine that directly processes pre-folded paper. According to needs, the paper padding machine can directly process and shape the pre-folded paper, and can also connect the wide-width paper guiding and deforming mechanism to process and shape the wide-width paper that is not pre-folded, thereby increasing the applicability of the existing paper padding machine, so that the existing paper padding machine can meet two types of paper materials (wide-width paper and pre-folded paper), can adapt to the processing needs of different paper materials, and does not affect the volume of the paper padding machine body.

[0057] Embodiment 2:

[0058] Figure 8 The structure of a wide-paper guiding and deforming mechanism according to another embodiment of the utility model is schematically shown.

[0059] refer to Figure 8 The wide-width paper guiding and deforming mechanism comprises an outer channel 1, an inner channel component 2, a guide roller 3 and a bottom roller 4. In addition, the wide-width paper guiding and deforming mechanism further comprises a gantry-shaped support structure 5, a support frame 6 and a guide roller 7.

[0060] Compared with the first embodiment, the structures and connection relationship of the outer channel 1, the inner channel component 2, the guide roller 3 and the bottom roller 4 of this embodiment are the same as those of the first embodiment, except that a gantry-shaped support structure 5, a support frame 6 and a guide roller 7 are added on the basis of the first embodiment.

[0061] The bottom of the outer channel 1 is mounted on a gantry-shaped support structure 5, specifically, refer to Figure 8 A mounting plate 51 is fixed on the top of the gantry-shaped support structure 5. The bottom of the outer channel 1 can be fixed on the top of the mounting plate 51 by a bolt-nut structure. A lug 511 is formed on the side of the mounting plate 51. The lug 511 is used to install and fix the head part of the paper pad machine ( Fig. 9 As shown) in order to improve the stability of the paper pad machine during operation, after the wide paper guiding and deforming mechanism is connected to the paper pad machine, the raw materials can be stacked in the gantry-shaped support structure 5, thereby greatly reducing the floor space occupied by the raw materials.

[0062] refer to Figure 8 In this embodiment, the gantry-shaped support structure 5 includes a first gantry-shaped support 501 and a second gantry-shaped support 502 arranged in parallel, a mounting plate 51 is fixed on the top of the first gantry-shaped support 501, the bottom of the outer channel 1 is mounted on the mounting plate 51 on the first gantry-shaped support 501, and the second gantry-shaped support 502 is used to install and fix the paper pad machine. A plate body can be installed on the top of the second gantry-shaped support 502, and the paper pad machine can be installed and fixed on the plate body on the top of the second gantry-shaped support 502 by a bolt-nut structure. The first gantry-shaped bracket 501 and the second gantry-shaped bracket 502 can be connected by two rods 503 to ensure the overall stability. In addition, the top of the second gantry-shaped bracket 502 is lower than the top of the first gantry-shaped bracket 501. In this way, it is convenient to make the bottom of the paper outlet of the outer channel 1 slightly higher than the bottom of the feeding port of the paper pad machine to ensure that the paper material will not be stuck at the junction of the two. After the wide paper guiding deformation mechanism is connected to the paper pad machine, the raw materials can be stacked in the first gantry-shaped bracket 501 and the second gantry-shaped bracket 502 ( Fig.10 The state shown in the figure) greatly reduces the floor space occupied by the raw materials, and the first gantry-shaped bracket 501 can provide support for the outer channel 1, and the second gantry-shaped bracket 502 can provide support for the paper pad machine.

[0063] refer to Figure 8The support frame 6 is fixed at the bottom of the first gantry-shaped bracket 501 and the second gantry-shaped bracket 502. Casters 61 are installed at the bottom of the support frame 6. There are four casters 61, which are respectively installed at the four corners of the support frame 6. The casters 61 can have their own braking function. The gantry-shaped bracket structure 5 can stand steadily through the support frame 6. In order to ensure the overall stability, the support frame 6 can be U-shaped, and the casters 61 at the bottom of the support frame 6 are used to facilitate the overall movement.

[0064] A guide rod 52 is installed on the gantry-shaped support structure 5. Specifically, refer to Figure 8 In this embodiment, a guide rod 52 is installed on one side of the top of the first gantry-shaped bracket 501, and a guide rod 52 is installed on both sides of the top of the second gantry-shaped bracket 502. In this way, the raw materials stacked in the gantry-shaped bracket structure 5 can smoothly enter between the inner channel component 2 and the outer channel 1 through the guide rod 52.

[0065] In addition, refer to Figure 8 A guide roller 7 is also installed between the left extension plate 1011 of the left side plate 101 of the outer channel 1 and the right extension plate 1021 of the right side plate 102. The guide roller 7 is located at the lower side of the guide roller 3. In this way, the raw materials stacked in the gantry-shaped support structure 5 pass between the guide roller 7 and the guide roller 3, bypass the top of the guide roller 3 and enter the bottom of the inner channel component 2 from the bottom of the bottom roller 4. The guide roller 7 can effectively prevent the paper between the guide roller 3 and the guide rod 52 from loosening.

[0066] Fig. 9 Schematic showing the paper pad machine installed in Figure 8 The state of the wide paper guide deformation mechanism is shown.

[0067] refer to Fig. 9 When the wide-width paper guiding and deforming mechanism of the utility model is connected to the paper pad machine 8 for processing pre-folded paper, the paper pad machine 8 is installed on the plate at the top of the second gantry-shaped bracket 502, and the paper outlet of the outer channel 1 is connected to the inlet of the paper pad machine 8, so that the bottom of the paper outlet of the outer channel 1 is slightly higher than the bottom of the inlet of the paper pad machine 8. At the same time, through size design, the width of the paper outlet of the outer channel 1 is made larger than the width of the inlet of the paper pad machine 8. In this way, it is ensured that the paper material will not be stuck at the junction of the paper outlet of the outer channel 1 and the inlet of the paper pad machine 8. In addition, it is also necessary to ensure that the bottom of the inner channel component 2 is lower than the bottom of the inner flow channel 81 in the paper pad machine 8 and lower than the center plane between the two upper and lower forming gears (not shown) in the paper pad machine 8.

[0068] Fig.10 Schematically shows Fig. 9 The wide paper guiding deformation mechanism and paper padding machine are shown in use.

[0069] refer to Fig.10 , stack multiple wide paper stacks 9 in the first gantry-shaped support 501 and the second gantry-shaped support 502, and pass the starting end of the wide paper stack 9 around the guide rod 52 ( Fig. 9 As shown), it then passes between the guide roller 7 and the guide roller 3, then bypasses the top of the guide roller 3 and enters the bottom of the inner channel component 2 from the bottom of the bottom roller 4. Under the traction of the paper pad machine 8, the wide paper moves from the paper inlet of the outer channel 1 to the paper outlet. Under the action of the outer channel 1, the two sides of the wide paper will be folded or bent toward the middle of the wide paper to form a three-dimensional paper material with a smaller width, so that the paper pad machine 8 can perform the next step of processing and forming. Since the top of the guide roller 3 is higher than the bottom of the bottom roller 4, the bottom of the inner channel component 2 is lower than the bottom of the bottom roller 4, and the two ends of the bottom roller 4 are conical, the two ends of the bottom roller 4 and the end of the inner channel component 2 close to the paper inlet of the outer channel 1 will pre-bend the two sides of the wide paper, so that the subsequent deformation of the two sides of the wide paper in the outer channel 1 is smooth, and the two sides on the inner channel component 2 The arc-shaped guide block 21 can prevent the two corners of the inner channel component 2 from cutting the paper material; when the raw material (i.e., paper material) is pre-folded paper, the inner channel component 2 can be removed (or the wide-width paper guiding and deforming mechanism can be directly removed as a whole), and the paper padding machine 8 can directly process and shape the pre-folded paper. The wide-width paper guiding and deforming mechanism of the utility model can be used as a supplementary structure of the current paper padding machine 8 that directly processes pre-folded paper. According to needs, the paper padding machine 8 can directly process and shape the pre-folded paper, and can also be connected to the wide-width paper guiding and deforming mechanism to process and shape the wide-width paper that is not pre-folded, thereby increasing the applicability of the existing paper padding machine, so that the existing paper padding machine can meet the needs of two types of paper materials (wide-width paper and pre-folded paper), can adapt to the processing needs of different paper materials, and does not affect the volume of the paper padding machine body.
