According to the deformation guiding structure, under the action of the deformation mechanism, the two side edges of the paper pad which is not pre-folded and is large in width are turned over or bent towards the middle of the paper pad, so that the paper pad which is narrow in width is formed, the deformation guiding structure can serve as a supplementary structure of a paper pad forming machine for directly machining the pre-folded paper pad at present, and the paper pad can be directly machined according to needs. An existing paper pad forming machine can directly machine and form a pre-folded paper pad, and can also be connected with a deformation guide structure to machine and form a wide single-layer paper pad which is not pre-folded, so that the applicability of the existing paper pad forming machine which directly machines the pre-folded paper pad can be improved; according to the paper pad forming machine, the existing paper pad forming machine can meet two types of paper materials (non-pre-folded paper materials with larger width and pre-folded paper materials with narrower width), and the volume of the paper pad forming machine body is not influenced.

Description

Technical Field

[0001] The utility model relates to a deformation guiding structure. Background Art

[0002] In logistics transportation, items are cushioned and packed, and cushioning materials are placed in packaging boxes or bags. Pillow-shaped three-dimensional paper cushions are one of them. Since the pillow-shaped three-dimensional paper cushion finally presents a double-layered, pleated three-dimensional structure, its raw material is a single-layer paper material with a larger width. The paper cushion forming machine guides the single-layer paper material with a larger width to form a cushioning three-dimensional structure with a certain thickness and a smaller width. However, due to the large width of the raw material itself, the guiding deformation structure of the paper cushion forming machine occupies a large volume, resulting in a large overall volume of the paper cushion forming machine, which occupies more space on the one hand and is inconvenient to carry and move on the other hand.

[0003] In order to overcome the problem of large volume of paper pad forming machines, the raw materials are currently pre-folded, that is, the raw materials are composed of a middle surface and folding surfaces on both sides of the middle surface, and the two folding surfaces are folded toward the middle surface. The edges of the two folding surfaces are spaced, aligned or overlapped, so that the width of the raw materials is greatly reduced, thereby reducing the volume of the guiding deformation structure of the equipment to reduce the overall volume of the equipment. The existing paper pad forming machines that directly process pre-folded paper pads can only meet the processing needs of pre-folded paper materials with a narrower width, and cannot simultaneously meet the processing needs of non-prefolded paper materials with a larger width, and have poor applicability. Therefore, how to develop a deformation guiding structure that allows the existing paper pad forming machines to meet the needs of two types of paper materials (non-prefolded paper materials with a larger width and pre-folded paper materials with a narrower width) without affecting the volume of the paper pad forming machine body is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0004] The purpose of the utility model is to provide a deformation guiding structure to solve at least one of the above technical problems.

[0005] According to one aspect of the utility model, a deformation guiding structure is also provided, comprising:

[0006] a stand, the height of the stand being adjustable; and

[0007] The deformation mechanism is used for folding or bending the two side edges of the paper pad toward the middle of the paper pad, and the deformation mechanism is arranged on the bracket.

[0008] The deformation guiding structure of the utility model is suitable for non-prefolded paper pads with a larger width. Under the action of the deformation mechanism, the two side edges of the non-prefolded paper pads with a larger width are folded or bent toward the middle of the paper pad, thereby forming a paper pad with a narrower width. The deformation guiding structure of the utility model can be used as a supplementary structure of the current paper pad forming machine that directly processes pre-folded paper pads. According to needs, the existing paper pad forming machine can directly process and form the pre-folded paper pads (without the need for a deformation guiding mechanism), and can also connect the deformation guiding structure to process and form non-prefolded wide single-layer paper pads, thereby increasing the applicability of the existing paper pad forming machine that directly processes pre-folded paper pads, so that the existing paper pad forming machine can meet the needs of two types of paper materials (non-prefolded paper materials with a larger width and prefolded paper materials with a narrower width) without affecting the volume of the paper pad forming machine body. According to the height of the paper pad forming machine, the height of the bracket can be adjusted so that the narrow paper pad output by the deformation mechanism can smoothly enter the paper pad forming machine.

[0009] In some embodiments, the deformation mechanism may include a guide roller, a depression portion, a deformation portion, and a discharge port.

[0010] The pressing part is located between the guide roller and the discharge port, and the guide roller is higher than the plane where the pressing part is located.

[0011] The width of the discharge port is smaller than the length of the guide roller.

[0012] The deformation part is located between the guide roller and the discharge port, and the deformation part can guide the two side edges of the paper pad to fold or bend toward the middle of the paper pad.

[0013] Thus, the non-pre-folded paper pad with a larger width passes over the guide roller from above and is transported from under the pressing part to the discharge port. Since the width of the discharge port is smaller than the length of the guide roller, under the action of the deformation part, the two side edges of the paper pad will be folded or bent toward the middle of the paper pad, so that the paper pad output from the discharge port is a pre-folded paper pad with two folding surfaces folded toward the middle surface, thereby forming a paper pad with a narrower width. After the existing paper pad forming machine is connected to the discharge port of the deformation mechanism, the paper pad forming machine can directly process and form the non-pre-folded wide single-layer paper pad.

[0014] In some embodiments, the deformation portion includes a guide portion and a flange portion.

[0015] The guide part is located between the guide roller and the discharge port, and the guide part can guide the two sides of the paper pad to fold or bend toward the middle of the paper pad.

[0016] The flange part is located between the guide part and the discharge port, the lowest point of the flange part is lower than the lowest point of the guide part, and the flange part can further fold or bend both side edges of the paper pad toward the middle of the paper pad.

[0017] As a result, the unpre-folded paper pad with a larger width passes over the guide roller from above and is transported from under the pressing part to the discharge port. Since the width of the discharge port is smaller than the length of the guide roller, under the action of the guide part, the two side edges of the paper pad will be folded or bent toward the middle of the paper pad. Then, under the action of the flange part, the two side edges of the paper pad continue to be compressed and deformed, and further folded or bent toward the middle of the paper pad, so that the paper pad output from the discharge port is a pre-folded paper pad with two folding surfaces folded toward the middle surface, thereby forming a paper pad with a narrower width. After the existing paper pad forming machine is connected to the discharge port of the deformation mechanism, the paper pad forming machine can directly process and form the unpre-folded wide single-layer paper pad.

[0018] In some embodiments, the deformation mechanism may further include a side guide portion, which is disposed on the guide portion and arranged at an obtuse angle to the guide portion, and the side guide portion can drive the two side edges of the paper pad to fold or bend toward the middle of the paper pad.

[0019] Therefore, since the side guide portion and the guide portion are arranged at an obtuse angle, the two side edges of the paper pad will be guided to bend under the action of the side guide portion, so that the two side edges of the paper pad are folded or bent toward the middle of the paper pad.

[0020] In some embodiments, the deformation mechanism may further include a pressing portion, which is located between the flanging portion and the discharge port, and the lowest point of the pressing portion is lower than the lowest point of the flanging portion. The pressing portion can press down on the two side edges of the paper pad that are folded or bent toward the middle to further deform the two side edges of the paper pad.

[0021] Thus, the portion of the paper pad that is folded or bent toward the middle will be pressed down by the edge pressing portion, so that the two side edges of the paper pad are further deformed.

[0022] In some embodiments, two pressing rollers distributed up and down and with adjustable spacing may be provided at the discharge port.

[0023] When the deformed paper pad passes between two pressing rollers, the two pressing rollers can indent and shape the deformed paper pad.

[0024] Thus, under the pressing action of the two pressing rollers, the deformed paper pad is shaped to form a stable pre-folded paper pad with a narrow width, and the distance between the two pressing rollers can be adjusted to accommodate paper pads of different thicknesses.

[0025] In some embodiments, a frame may be further included, the deformation mechanism is arranged on the frame, and the frame is arranged on the bracket.

[0026] The guide roller is set on one side of the frame, and the discharge port is set on the other side of the frame.

[0027] The frame is provided with a separation rod for separating the two sides of the paper pad, and the bottom of the separation rod is arranged on the pressing part.

[0028] A guide roller is arranged in the frame, and the guide roller is located between the guide roller and the end of the pressing part.

[0029] Thus, the guide roller can guide the paper pad to smoothly enter from above the guide roller below the pressing part, and the separation rod can make the two sides of the paper pad fold or bend toward the middle with nearly equal size, ensuring the consistency of the pre-folding of the paper pad.

[0030] In some embodiments, the bottom of the guide roller may be flush with the bottom of the depressed portion.

[0031] Thus, in this case, it is possible to prevent the edge of the depressed portion from causing cross-cutting force damage to the paper pad.

[0032] In some embodiments, the deformation mechanism may include a guide roller, a bottom roller, and a flow channel.

[0033] The guide roller and bottom roller are both located at the entrance of the flow channel, and the guide roller is located obliquely above the bottom roller.

[0034] Both ends of the bottom roller are conical.

[0035] The flow channel converges from the inlet to the outlet.

[0036] As a result, the unpre-folded paper pad with a larger width passes over the guide roller from above and then enters the flow channel from below the bottom roller. Since the flow channel is contracted from the inlet to the outlet, under the action of the flow channel, the two side edges of the paper pad will be folded or bent toward the middle of the paper pad, and since both ends of the bottom roller are conical, the two ends of the bottom roller will pre-bend the two side edges of the paper pad, so that the subsequent deformation of the two side edges of the paper pad in the flow channel will be smoother, and the paper pad output from the outlet of the flow channel is a pre-folded paper pad with a narrower width. After the existing paper pad forming machine is connected to the discharge port of the deformation mechanism, the paper pad forming machine can directly process and form the unpre-folded wide single-layer paper pad.

[0037] In some embodiments, the flow channel may include a bottom plate and a side plate, the width of the bottom plate gradually decreases from the inlet to the outlet, the side plates are arranged on both sides of the bottom plate, the ends of the guide rollers are arranged on the side plates, and the ends of the bottom rollers are arranged on the side plates.

[0038] Therefore, when the paper pad passes through the flow channel, the side plates will drive the two sides of the paper pad to deform, driving the two sides of the paper pad to fold or bend toward the middle of the paper pad, so that the paper pad output from the outlet of the flow channel is a pre-folded paper pad with a narrower width.

[0039] In some embodiments, the side panels may be in a bent shape that can fold or bend both sides of the paper pad toward the middle of the paper pad.

[0040] Thus, the bent side plates drive the two side edges of the paper pad to fold or bend toward the middle of the paper pad.

[0041] In some embodiments, a rotation adjustment unit for adjusting the pitch angle of the deformation mechanism may be further included, and the rotation adjustment unit is disposed between the deformation mechanism and the bracket.

[0042] Therefore, when the existing paper pad forming machine is connected to the deformation guide structure of the utility model, the pitch angle of the deformation mechanism can be adjusted by rotating the adjustment part according to the height of the paper pad forming machine so that the pre-folded paper pad output from the discharge port can smoothly enter the paper pad forming machine, and the height of the bracket can also be adjusted at the same time.

[0043] In some embodiments, the rotation adjustment part may include a support frame, a mounting plate and an adjustment rod. The support frame is arranged on the top of the bracket, the mounting plate is arranged on the deformation mechanism, and a plurality of plug holes arranged in an arc are provided on the mounting plate. The adjustment rod passes through the support frame and is plugged into the plug hole.

[0044] Therefore, when the adjusting rod is inserted into different insertion holes on the mounting plate, the pitch angle of the deformation mechanism is different. According to the height of the paper pad forming machine, the adjusting rod can be inserted into a suitable insertion hole on the mounting plate.

[0045] In some embodiments, a connecting rod for connecting to a paper pad forming machine may also be included, one end of the connecting rod is disposed on a bracket or a deformation mechanism and is detachably connected to the bracket or the deformation mechanism, and the other end of the connecting rod can be connected to an external paper pad forming machine.

[0046] Therefore, the existing paper pad forming machine can be connected with the deformation guiding structure of the utility model through the connecting rod to ensure the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

It can be adjusted as needed, that is, the overall height of the bracket 1 can be adjusted as needed; the structure of the bracket 1 can also be: a telescopic rod structure, which is the same as the structural principle of the telescopic rod of the suitcase, and will not be repeated here; the structure of the bracket 1 can also be: the bracket 1 includes an inverted U-shaped telescopic tube and an I-shaped base frame, the two tube bodies of the inverted U-shaped telescopic tube are formed by connecting multiple sections of connecting tubes in sequence, and the two adjacent connecting tubes are connected by threads. The bottom of the two tube bodies of the inverted U-shaped telescopic tube is installed on the I-shaped base frame, and casters are installed at the bottom of the I-shaped base frame. According to the height requirements of the bracket 1, one or more connecting tubes in the two tube bodies of the inverted U-shaped telescopic tube can be unscrewed or one or more connecting tubes in the two tube bodies of the inverted U-shaped telescopic tube can be added, so as to adjust the overall height of the bracket 1. According to the height of the paper pad forming machine, the height of the bracket 1 can be adjusted so that the paper pad with a narrow width output by the deformation mechanism can smoothly enter the paper pad forming machine.

[0062] The deformation mechanism is installed on the bracket 1, and the deformation mechanism can fold or bend the two sides of the paper pad toward the middle of the paper pad. Specifically, the deformation mechanism is installed on the frame, and the frame is used to carry the deformation mechanism, and the frame is installed on the bracket 1.

[0063] refer to Figures 1 to 3 The frame includes a right side plate 301, a left side plate 302, a cross beam 303 and a bottom beam 304. Figure 1 The right side plate 301 and the left side plate 302 are arranged opposite to each other, and the space between the right side plate 301 and the left side plate 302 is contracted along the direction A. The top of the right side plate 301 and the top of the left side plate 302 are connected by a crossbeam 303. Figure 3 The bottom of the right side plate 301 and the bottom of the left side plate 302 are connected by a bottom beam 304 .

[0064] refer to Figures 1 to 3 The deformation mechanism includes a guide roller 21, a pressing portion 22, a deformation portion, a discharge port 25, a side guide portion 26 and a pressing portion 27.

[0065] refer to Figures 1 to 3The guide roller 21 is installed on one side of the frame. Specifically, one end of the guide roller 21 is installed on the end of the right side plate 301, and the other end of the guide roller 21 is installed on the end of the left side plate 302. When subjected to external force, the guide roller 21 can be set to rotate between the right side plate 301 and the left side plate 302, or it can be set not to rotate.

[0066] refer to Figure 2 The discharge port 25 is located at the other side of the frame. Specifically, two pressing rollers 251 distributed up and down are installed at the discharge port 25. One end of the pressing roller 251 is installed on the end of the right side plate 301, and the other end of the pressing roller 251 is installed on the end of the left side plate 302. The gap between the two pressing rollers 251 forms the discharge port 25. The width of the discharge port 25 is smaller than the length of the guide roller 21. When the deformed paper pad passes between the two pressing rollers 251, the two pressing rollers 251 can indent and shape the deformed paper pad. The spacing between the two pressing rollers 251 can be adjusted as needed to adapt to paper pads of different thicknesses. For example, a plurality of mounting holes are longitudinally arranged on the right side plate 301, and a plurality of mounting holes are longitudinally arranged on the left side plate 302. The two ends of the pressing roller 251 are respectively installed in the mounting holes. The pressing roller 251 can be adjusted as needed to be installed in a suitable mounting hole to adjust the spacing between the two pressing rollers 251. As long as the structure that can adjust the spacing between the two pressing rollers 251 can be achieved, it is not limited here.

[0067] refer to Figures 1 to 3 The pressing portion 22 is installed on the bottom beam 304, and is located between the right plate 301 and the left plate 302. The pressing portion 22 is plate-shaped and is located between the guide roller 21 and the discharge port 25. The guide roller 21 is higher than the plane where the pressing portion 32 is located.

[0068] refer to Figures 1 to 3 A guide roller 32 is installed in the frame, and both ends of the guide roller 32 are installed on the crossbeam 303 through a rod. The guide roller 32 is located between the guide roller 21 and the end of the depression part 22, and the bottom of the guide roller 32 is flush with the bottom of the depression part 22; the paper pad with a larger width that is not pre-folded passes around the guide roller 21 from above, and then passes around the guide roller 32 from below to enter the bottom of the depression part 22 and is transported to the direction of the discharge port 25. The guide roller 32 can prevent the edge of the depression part 22 from causing cross-cutting force damage to the paper pad.

[0069] The deformation part is located between the guide roller 21 and the discharge port 25. The deformation part can guide the two sides of the paper pad to fold or bend toward the middle of the paper pad. The deformation part includes a guide part 23 and a flange part 24. Specifically, refer to Figures 1 to 3There are two guide parts 23, and the guide part 23 is a plate body in a trapezoidal shape. The edge of one guide part 23 is fixed on the right plate 301 (it can also be integrally formed), and the edge of the other guide part 23 is fixed on the left plate 302 (it can also be integrally formed). The guide part 23 is located between the guide roller 21 and the discharge port 25. Since the plane where the depression part 32 is located is lower than the guide roller 21, the height of the end of the guide part 23 away from the guide roller 21 is lower than the height of the end of the guide part 23 close to the guide roller 21, that is, the guide part 23 is downslope along the A direction, refer to Figure 1 Along the A direction, the area between the two guide parts 23 is in a contracted shape. Since the paper pad with a larger width that has not been pre-folded passes around the guide roller 21 from above the guide roller 21, passes around the guide roller 32 from below the guide roller 32, enters the bottom of the pressing part 22, and is transported toward the discharge port 25, under the action of the two guide parts 23, the two side edges of the paper pad will be folded or bent toward the middle of the paper pad.

[0070] refer to Figures 1 to 3 The side guide portion 26 is installed on the guide portion 23. The side guide portion 26 and the guide portion 23 are integrally formed. The side guide portion 26 can be formed by folding the edge of the guide portion 23. The side guide portion 26 and the guide portion 23 are arranged at an obtuse angle. Both guide portions 23 are provided with side guide portions 26. Under the action of the two side guide portions 26, the two side edges of the paper pad will be guided to bend, so that the two side edges of the paper pad are further folded or bent toward the middle of the paper pad.

[0071] refer to Figures 1 to 3 There are two flanging portions 24, and the flanging portions 24 are plate-shaped. The edge of one flanging portion 24 is fixed on the right plate 301 (it can also be integrally formed), and the edge of the other flanging portion 24 is fixed on the left plate 302 (it can also be integrally formed). The flanging portion 24 is located between the guide portion 23 and the discharge port 25. The height of the end of the flanging portion 24 away from the guide roller 21 is lower than the height of the end of the flanging portion 24 close to the guide roller 21, that is, the flanging portion 24 is downslope along the A direction, and the lowest point of the flanging portion 24 is lower than the lowest point of the guide portion 23. Preferably, the highest point of the flanging portion 24 is slightly lower than the lowest point of the guide portion 23, that is, along the A direction, the guide portion 23 and the flanging portion 24 are downslope as a whole. Figure 1 Along the A direction, the area between the two flange portions 24 is in a contracted shape and follows the contraction trend of the contraction area between the two guide portions 23. After the paper pad passes through the guide portion 23 and the side guide portion 26, under the action of the two flange portions 24, the two side edges of the paper pad continue to be compressed and deformed, and further folded or bent toward the middle of the paper pad.

[0072] refer to Figures 1 to 3There are two edge pressing parts 27, and the edge pressing parts 27 are in the shape of a plate. The edge of one edge pressing part 27 is fixed on the right side plate 301 (it can also be integrally formed), and the edge of the other edge pressing part 27 is fixed on the left side plate 302 (it can also be integrally formed). The edge pressing part 27 is located between the flange part 24 and the discharge port 25. The free ends of the edge pressing parts 27 can be arranged horizontally, and a certain gap is left between the free ends of the two edge pressing parts 27. The lowest point of the edge pressing part 27 is lower than the lowest point of the flange part 24. In this way, after the paper pad passes through the action of the flange part 24, the two edge pressing parts 27 can press down the two side edges of the paper pad that are folded or bent toward the middle to further deform the two side edges of the paper pad.

[0073] refer to Figures 1 to 3 A separation rod 31 is installed in the frame. Specifically, the bottom of the separation rod 31 is fixed on the bottom pressure portion 22, and the top of the separation rod 31 is fixed on the crossbeam 303. The separation rod 31 is used to separate the two side edges of the paper pad. The separation rod 31 is located in the middle position of the area between the two guide portions 23. The separation rod 31 can make the two side edges of the paper pad fold or bend toward the middle with nearly equal sizes to ensure the consistency of the pre-folding of the paper pad.

[0074] refer to Figure 1 The unfolded paper pad with a larger width passes over the guide roller 21 from above along the direction A, and then passes over the guide roller 32 from below the guide roller 32 to enter the lower part 22 and be transported to the direction of the discharge port 25. Since the width of the discharge port 25 is smaller than the length of the guide roller 21, under the action of the guide part 23 and the side guide part 26, the two sides of the paper pad will be folded or bent toward the middle of the paper pad, and the separation rod 31 can make the two sides of the paper pad be folded or bent toward the middle with nearly the same size, and then under the action of the two flange parts 24, the paper pad is The two side edges of the pad continue to be deformed by compression, and further folded or bent toward the middle of the paper pad. After the paper pad passes through the action of the flange portion 24, the two edge pressing portions 27 can press down on the two side edges of the paper pad that are folded or bent toward the middle to further deform the two side edges of the paper pad. When the deformed paper pad passes between the two pressing rollers 251, the deformed paper pad is shaped under the pressing action of the two pressing rollers 251, and the paper pad output from the discharge port 25 is a pre-folded paper pad with two folding surfaces folded toward the middle surface, thereby forming a stable pre-folded paper pad with a narrow width.

[0075] The rotation adjustment part is installed between the deformation mechanism and the bracket 1. The rotation adjustment part can adjust the pitch angle of the deformation mechanism. In this embodiment, the rotation adjustment part is installed between the frame and the bracket 1; specifically: Figure 1 and Figure 3The rotation adjustment part includes a support frame 41, a mounting plate 42, an adjustment rod 43 and a latch 44. The support frame 41 is fixed to the top of the bracket 1. Two first side plates 411 arranged opposite to each other are formed on the support frame 41. The mounting plate 42 is fixed to the bottom of the frame body. The mounting plate 42 is specifically fixed to the bottom beam 304 of the frame body. Two second side plates 422 arranged opposite to each other are formed on the mounting plate 42. A plurality of plug holes 421 arranged in an arc are formed on the two second side plates 422. Each plug hole 421 on one second side plate 422 is connected to a plug hole 421 on another second side plate 422. The adjusting rod 43 passes through a first side plate 411 on the supporting frame 41 and is inserted into a plug hole 421 on a second side plate 422 on the mounting plate 42. The plug pin 44 passes through another first side plate 411 on the supporting frame 41 and is inserted into a plug hole 421 on another second side plate 422 on the mounting plate 42. When the adjusting rod 43 and the plug pin 44 are inserted into different plug holes 421 on the mounting plate 42, the pitch angle of the frame body is different. According to the height of the paper pad forming machine, the adjusting rod 43 and the plug pin 44 can be inserted into appropriate plug holes 421 on the mounting plate 42.

[0076] One end of the connecting rod is mounted on the bracket 1 or the deformation mechanism, and the connecting rod is detachably connected to the bracket 1 or the deformation mechanism, and the other end of the connecting rod can be connected to an external paper pad forming machine. Specifically, one end of the connecting rod is detachably mounted (such as threaded connection, plug-in connection, etc.) on the bottom of the bottom beam 304 of the frame body that carries the deformation mechanism, and the other end of the connecting rod can be detachably connected (such as threaded connection, plug-in connection, etc.) to the external paper pad forming machine. The existing paper pad forming machine can be connected to the deformation guide structure of the utility model through the connecting rod to ensure the overall stability. In other embodiments, one end of the connecting rod can also be detachably mounted (such as threaded connection, plug-in connection, etc.) on the deformation mechanism, such as the bottom of the depression part, and can also be detachably mounted (such as threaded connection, plug-in connection, etc.) on the bracket 1.

[0077] Figure 4 Schematically shows Figure 1 The deformation guide structure shown is in use after being connected to an existing paper pad forming machine.

[0078] refer to Figure 4 The existing paper pad forming machine 200 is connected to the deformation guide structure of the first embodiment through the connecting rod 5, and multiple stacks of paper pads 100 are placed on the cart or the carrier plate 300. Each stack of paper pads 100 is a continuous paper pad that is not pre-folded. The number of stacks of paper pads 100 arranged front and back along the paper-loading direction of the paper pad, i.e., the F direction, is four. The paper pads 100 are placed in a row on the cart or the carrier plate 300. The number of stacks of paper pads 100 in the height direction on the cart or the carrier plate 300 is also four, for a total of sixteen stacks.

[0079] refer to Figure 4 , the head (starting end) of the unprefolded paper pad 100 with a larger width is passed around the guide roller 21 from above the guide roller 21 along the F direction, and then passed around the guide roller 32 from below the guide roller 32 to enter the bottom of the pressing part 22, and is sent out from the discharge port 25 through the gap between the two pressing rollers 21. The two sides of the paper pad will be folded or bent toward the middle of the paper pad under the action of the guide part 23 and the side guide part 26, the flanging part 24, and the pressing part 27 in turn. Under the pressing action of the two pressing rollers 251, the deformed paper pad is shaped, and the paper pad output from the discharge port 25 is a prefolded paper pad with two folding surfaces folded toward the middle surface, thereby forming a stable prefolded paper pad with a narrower width. The formed prefolded paper pad enters the paper pad forming machine 200, and the paper pad forming machine 200 makes the paper pad into a three-dimensional buffer paper pad; the deformation guiding structure of the utility model can be used as a paper for directly processing prefolded paper pads The supplementary structure of the pad forming machine 200, according to needs, the existing paper pad forming machine 200 can directly process and shape the pre-folded paper pad (without the need for a deformation guide mechanism), and can also connect the deformation guide structure of the utility model to process and shape the non-prefolded wide single-layer paper pad, thereby increasing the applicability of the existing paper pad forming machine 200 that directly processes the pre-folded paper pad, so that the existing paper pad forming machine 200 can meet two types of paper materials (wider non-prefolded paper materials and narrower prefolded paper materials) without affecting the volume of the paper pad forming machine 200 body. In addition, the height-adjustable bracket 1 can cooperate with the height change of the feed port of the paper pad forming machine. When the height of the feed port of the paper pad forming machine cannot be adapted by rotating the adjustment part, the height of the bracket 1 can be adjusted so that the narrower paper pad output by the discharge port 25 can smoothly enter the paper pad forming machine.

[0081] Figures 5 to 7 The structure of a deformation guiding structure in another embodiment of the present invention is schematically shown.

[0082] refer to Figures 5 to 7 The deformation guiding structure includes a bracket 1 and a deformation mechanism. In addition, the deformation guiding structure may also include a bracket body, a rotation adjustment part and a connecting rod 5.

[0083] In this embodiment, the structure of the bracket 1, the structure of the rotation adjustment part, and the connecting rod 5 are the same as those in the first embodiment and are not described in detail. Only the structure of the deformation mechanism is different from that in the first embodiment.

[0084] refer to Figures 5 to 7 The deformation mechanism includes a guide roller 61, a bottom roller 62 and a flow channel 63.

[0085] refer to Figure 5The flow channel 63 is convergent in the direction from the inlet to the outlet, that is, in the direction B.

[0086] refer to Figures 5 to 7 The flow channel 63 includes a bottom plate 631 and two side plates 632. The width of the bottom plate 631 gradually decreases from the inlet to the outlet, that is, in the direction B. The two side plates 632 are respectively arranged on both sides of the bottom plate 631. The side plates 632 and the bottom plate 631 can be integrally formed.

[0087] refer to Figure 5 One end of the guide roller 61 is installed on an extension of a side plate 632 in the opposite direction of direction B, and the other end of the guide roller 61 is installed on an extension of another side plate 632 in the opposite direction of direction B. When subjected to external force, the guide roller 61 can be set to rotate between the extensions of the two side plates 632, or it can be set not to rotate.

[0088] refer to Figure 5 One end of the bottom roller 62 is mounted on an extension of a side plate 632 in the opposite direction of direction B, and the other end of the bottom roller 62 is mounted on an extension of another side plate 632 in the opposite direction of direction B. When subjected to external force, the bottom roller 62 can be set to rotate between the extensions of the two side plates 632, or it can be set not to rotate. The guide roller 61 and the bottom roller 62 are both located at the entrance of the flow channel 63, and the guide roller 61 is located obliquely above the bottom roller 62.

[0089] refer to Figures 5 to 7 , both ends 621 of the bottom roller 62 are conical, and the unpre-folded wider paper pad passes over the guide roller 61 from above and enters the flow channel 63 from below the bottom roller 62. Since the flow channel 63 is contracted from the entrance to the exit, under the action of the flow channel 63, the two side edges of the paper pad will be folded or bent toward the middle of the paper pad. Moreover, since both ends 621 of the bottom roller 62 are conical, the two ends 621 of the bottom roller 62 will pre-bend the two side edges of the paper pad, so that the subsequent deformation of the two side edges of the paper pad in the flow channel 63 will be smoother.

[0090] refer to Figures 5 to 7 The side panels 632 are bent, and the two bent side panels 632 can guide the two side edges of the paper pad to fold or bend toward the middle of the paper pad.

[0091] The rotation adjustment part is installed between the deformation mechanism and the bracket 1, and the rotation adjustment part can adjust the pitch angle of the deformation mechanism. In this embodiment, the rotation adjustment part is installed between the flow channel 63 and the bracket 1, and the rotation adjustment part can adjust the pitch angle of the flow channel 63. Figure 6The rotation adjustment part includes a support frame 41, a mounting plate 42, an adjustment rod 43 and a latch 44. The structure of the rotation adjustment part is the same as that of the second embodiment and is not repeated here. The only difference is that the support frame 41 is fixed to the top of the bracket 1, the mounting plate 42 is fixed to the bottom of the flow channel 63, and the adjustment rod 43 and the latch 44 are plugged into different plug holes 421 on the mounting plate 42. The pitch angle of the flow channel 63 is different. According to the height of the paper pad forming machine, the adjustment rod 43 and the latch 44 can be plugged into appropriate plug holes 421 on the mounting plate 42.

[0092] One end of the connecting rod 5 is mounted on the bracket 1 or the deformation mechanism, and the connecting rod 5 is detachably connected to the bracket 1 or the deformation mechanism. The other end of the connecting rod 5 can be connected to an external paper pad forming machine. Specifically, refer to Figure 5 One end of the connecting rod 5 is detachably mounted (such as threaded connection, buckle connection, etc.) on the bottom of the bottom plate 631 of the flow channel 63 of the deformation mechanism, and the other end of the connecting rod 5 can be detachably connected (such as threaded connection, buckle connection, etc.) to the external paper pad forming machine. The existing paper pad forming machine can be connected to the deformation guide structure of the utility model through the connecting rod 5 to ensure the overall stability. In other embodiments, one end of the connecting rod 5 can also be detachably mounted (such as threaded connection, buckle connection, etc.) on the bracket 1.

[0093] Figure 8 Schematically shows Figure 5 The deformation guide structure shown is in use after being connected to an existing paper pad forming machine.

[0094] refer to Figure 8 The existing paper pad forming machine 200 is connected to the deformation guide structure of the second embodiment through the connecting rod 5, and multiple stacks of paper pads 100 are placed on the cart or the carrying plate 300. Each stack of paper pads 100 is a continuous paper pad that is not pre-folded. The number of stacks of paper pads 100 arranged front and back along the paper-loading direction of the paper pad, i.e., the F direction, is four. The paper pads 100 are placed in a row on the cart or the carrying plate 300. The number of stacks of paper pads 100 in the height direction on the cart or the carrying plate 300 is also four, for a total of sixteen stacks.

[0095] refer to Figure 8, the head (starting end) of the unprefolded paper pad 100 with a larger width is passed over the guide roller 61 from above in the direction F, and then enters the flow channel 63 from below the bottom roller 62. Since the flow channel 63 is in a contracted shape from the entrance to the exit, under the action of the flow channel 63, the two sides of the paper pad will be folded or bent toward the middle of the paper pad, and since the two end portions 621 of the bottom roller 62 are both conical, the two end portions 621 of the bottom roller 62 will pre-bend the two sides of the paper pad, so that the subsequent deformation of the two sides of the paper pad in the flow channel 63 will be smoother, and the paper pad output from the exit of the flow channel 63 is a pre-folded paper pad with a narrower width. The formed pre-folded paper pad enters the paper pad forming machine 200, and the paper pad forming machine 200 makes the paper pad into a three-dimensional buffer paper pad; the deformation guiding structure of the utility model can be used as a supplement to the current paper pad forming machine 200 that directly processes pre-folded paper pads Filling structure, according to needs, the existing paper pad forming machine 200 can directly process and shape the pre-folded paper pad (without the need for a deformation guiding mechanism), and can also connect the deformation guiding structure of the utility model to process and shape the non-prefolded wide single-layer paper pad, thereby increasing the applicability of the existing paper pad forming machine 200 that directly processes the pre-folded paper pad, so that the existing paper pad forming machine 200 can meet two types of paper materials (wider non-prefolded paper materials and narrower prefolded paper materials) without affecting the volume of the paper pad forming machine 200 body. In addition, the height-adjustable bracket 1 can cooperate with the height change of the feed port of the paper pad forming machine. When the height of the feed port of the paper pad forming machine cannot be adapted by rotating the adjustment part, the height of the bracket 1 can be adjusted so that the narrower paper pad output from the outlet of the flow channel 63 can smoothly enter the paper pad forming machine.
