Description

Technical Field

[0001] The utility model relates to a bubble pressing machine with a feeding structure, and relates to the field of protective packaging material manufacturing equipment. Background Art

[0002] In the existing express logistics transportation, in order to protect the transported items, the items will be well protected, such as earthquake and collision protection, and the items in the packaging box will also be protected. At present, the items are generally supported by stuffing air cushions, bubble bags or paper pads in the packaging box to achieve the purpose of protection.

[0003] Take paper pads as an example. Generally, they can be produced by equipment. Bubble paper is one of the protective paper pads. Bubble paper is produced by bubble pressing machines. The working principle of bubble pressing machines is to emboss the paper material through a pair of concave and convex rollers, so that the surface of the formed paper material presents uneven ridges and pits. When the bubble paper is wrapped around the object, the three-dimensional shape formed by the ridges and pits can play a protective, shock-resistant and cushioning role for the object.

[0004] Since bumps and depressions are formed on the surface of paper when it is processed, the paper is easily broken during processing, resulting in reduced stability of the bumps and depressions, thereby reducing the protective, shock-resistant and buffering effects. Some bubble presses are designed with a structure at the entrance to reduce the width of the paper entering the equipment to reduce the probability of the paper being torn. The structure includes two mounting rods arranged in parallel at the entrance of the equipment, each mounting rod is provided with a plurality of circular rings, and the circular rings on the two mounting rods overlap in their projections along the length direction parallel to the mounting rods. The paper passes between the circular rings on the two mounting rods and then enters the bubble press. When the paper passes between the two mounting rods, its width direction will form a wave shape due to the action of the circular rings, thereby shortening the size of the paper in the width direction, thereby reducing the probability of the subsequent paper being torn.

[0005] However, since the circular rings on the two mounting rods are staggered and their projections along the length direction parallel to the mounting rods overlap, when inserting the paper through adjacent circular rings, the paper needs to be aligned and passed through each required circular ring, and the paper needs to be inserted between the required circular rings on the two mounting rods little by little. This method, on the one hand, is time-consuming, resulting in a more difficult and inefficient paper threading process, and on the other hand, it is easy to guide the paper material to a skewed feeding path, causing the subsequently input paper to deviate from the normal input path, which may cause a paper jam.

[0006] Therefore, how to overcome the above technical defects of the bubble press machine for producing bubble paper is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0007] The purpose of the utility model is to provide a bubble pressing machine with a feeding structure to solve at least one of the above technical problems.

[0008] According to one aspect of the utility model, a bubble pressing machine with a feeding structure is provided, comprising:

[0009] An upper mounting rod and a lower mounting rod are arranged to slide relative to each other at intervals, the upper mounting rod is provided with a plurality of upper pressing wheels, the lower mounting rod is provided with a plurality of lower pressing wheels, at least some of the upper pressing wheels and at least some of the lower pressing wheels are staggeredly distributed in the length direction of the gap between the upper mounting rod and the lower mounting rod, and the paper material passes between the upper mounting rod and the lower mounting rod;

[0010] a first driving component, the first driving component drives the upper mounting rod and the lower mounting rod to move closer or farther away;

[0011] When the upper mounting rod and the lower mounting rod are close to each other, the shortest path for the paper material formed by the upper pressing wheel and the lower pressing wheel is zigzag.

[0012] When the upper clamping wheel and the lower clamping wheel move away from each other, the shortest path for the paper material to pass formed by the upper pressing wheel and the lower pressing wheel is in a straight line.

[0013] The bubble pressing machine with a feeding structure of the utility model has an upper mounting rod and a lower mounting rod that can move closer to or farther from each other. When loading is required, the first driving component drives the upper mounting rod and the lower mounting rod to move away from each other, and then the paper can be easily put on the pressing wheel and the lower pressing wheel without any hindrance. After the loading is completed, the first driving component drives the upper mounting rod and the lower mounting rod to move closer to each other, so that the upper pressing wheel and the lower pressing wheel re-squeeze the paper to complete the loading process. The bubble pressing machine of the utility model has simple and convenient loading of paper, and there is no need to insert the paper between the upper pressing wheel and the lower pressing wheel little by little. Moreover, it is not easy to skew or deviate from the conveying path of the paper, which ensures the accuracy of the conveying path and greatly improves the efficiency of paper loading.

[0014] In some embodiments, a slideway and a mounting block may be further included, the lower mounting rod is mounted on the mounting block, and the first driving component drives the mounting block to move on the slideway. Thus, the first driving component drives the mounting block to slide on the slideway, and the lower mounting rod and the mounting block rise and fall synchronously, so that the upper mounting rod and the lower mounting rod are in contact with each other and close to each other.

[0015] In some embodiments, a bubble pressing mechanism and a transmission mechanism may also be included, wherein the bubble pressing mechanism is a pair of bubble pressing rollers distributed up and down and rotating in opposite directions, the first driving component drives the bubble pressing rollers to rotate, and the first driving component drives the mounting block to move through the transmission mechanism. Thus, the first driving component can not only realize the approach or separation of the lower mounting rod and the upper mounting rod through the transmission mechanism, but also drive the bubble pressing rollers to rotate, so as to realize two driving functions of one power source, thereby reducing costs, reducing weight, and improving space utilization.

[0016] In some embodiments, the transmission mechanism may include a synchronous belt, a one-way wheel body, a first swing rod and a connecting rod.

[0017] The synchronous belt ring is arranged on the driving shaft of the first driving component, the shaft body of the foam pressing roller, and the one-way wheel body. The first driving component can drive the foam pressing roller and the one-way wheel body to rotate synchronously.

[0018] One end of the first swing rod is fixed on the shaft component of the one-way wheel body, and the other end is hinged to one end of the connecting rod.

[0019] The other end of the connecting rod is arranged on the mounting block.

[0020] The end of the lower mounting rod is arranged on the mounting block, and the other end of the connecting rod can drive the mounting block to move up and down.

[0021] Therefore, when the bubble pressing machine is normally producing paper pads, the first driving component drives the bubble pressing roller to rotate through the synchronous belt, and the one-way wheel body is one-way, and the rotating shaft of the one-way wheel body does not rotate. At this time, the upper pressing wheel and the lower pressing wheel keep pressing the paper material. When loading is required, the driving shaft of the first driving component rotates in the opposite direction, that is, the synchronous belt transmits in the opposite direction, and the synchronous belt drives the rotating shaft of the one-way wheel body to rotate. The rotating shaft of the one-way wheel body drives the first swing arm to rotate, and the rotation of the first swing arm drives one end of the connecting rod to move, that is, drives one end of the connecting rod to rotate with the rotating shaft of the one-way wheel body as the rotation center. When the paper is loaded, the driving shaft of the first driving component continues to rotate in the opposite direction to move the mounting block upward, and the lower pressing wheel approaches the upper pressing wheel and clamps the paper to complete the reset. At this time, the loading is completed, and the driving shaft of the first driving component can be rotated forward subsequently to make the foam pressing roller emboss the paper.

[0022] In some embodiments, the transmission mechanism may further include a one-way wheel body, a first swing rod and a connecting rod.

[0023] The one-way wheel body is arranged on the driving shaft of the first driving component, and the first driving component can drive the foam pressing roller and the one-way wheel body to rotate.

[0024] One end of the first swing rod is fixed on the shaft component of the one-way wheel body, and the other end is hinged to one end of the connecting rod.

[0025] The other end of the connecting rod is arranged on the mounting block.

[0026] The end of the lower mounting rod is arranged on the mounting block, and the other end of the connecting rod can drive the mounting block to move up and down.

[0027] Therefore, when the bubble pressing machine is normally producing paper pads, the first driving component drives the bubble pressing roller and the one-way wheel body to rotate, and since the one-way wheel body is one-way, the rotating shaft of the one-way wheel body does not rotate. At this time, the upper pressing wheel and the lower pressing wheel keep pressing the paper. When material loading is needed, the driving shaft of the first driving component rotates in the opposite direction, the rotating shaft of the one-way wheel body rotates, and the rotating shaft of the one-way wheel body drives the first swing arm to rotate. The rotation of the first swing arm drives one end of the connecting rod to move, that is, drives one end of the connecting rod to rotate with the rotating shaft of the one-way wheel body as the rotation center, and the other end of the connecting rod can drive the mounting block to move downward on the slide, and the mounting block drives the lower mounting rod to move downward, and the lower mounting rod is away from the upper mounting rod, and then the paper can be easily passed between the upper pressing wheel and the lower pressing wheel, and the paper can be put between the two foam pressing rollers; after the loading is completed, the driving shaft of the first driving component continues to rotate in the opposite direction, so that the mounting block moves upward, the lower pressing wheel approaches the upper pressing wheel and clamps the paper, and the resetting is completed. At this time, the loading is completed, and the driving shaft of the first driving component can be subsequently rotated forward, so that the foam pressing roller embosses the paper.

[0028] In some embodiments, the transmission mechanism further includes a linkage shaft, a transmission rod and two second swing rods, and the number of the linkage shaft, the mounting block and the slideway are all two.

[0029] One end of a linkage shaft is hinged to the other end of the connecting rod, and the other end of the linkage shaft slides and rotates on one of the mounting blocks. One end of a second swing rod is hinged to the linkage shaft, and the other end of the second swing rod is fixed to one end of the transmission rod.

[0030] One end of another second swing rod is fixed on the other end of the transmission rod, one end of another linkage shaft is hinged on the other end of the second swing rod, and the other end of the linkage shaft slides and rotates on another mounting block, and the mounting block is slidably mounted on another slideway.

[0031] The two ends of the lower mounting rod are respectively hinged on two mounting blocks, and the two mounting blocks move on two slideways respectively.

[0032] Therefore, when loading is required, the driving shaft of the first driving component rotates in the opposite direction, and the connecting rod drives a linkage shaft to move. The moving linkage shaft drives a transmission rod to rotate through a second rocker rod. The rotating transmission rod drives another second rocker rod to swing around the transmission rod. The second rocker rod can drive another linkage shaft to move, and the moving linkage shaft drives another mounting block to slide up and down on another slide, so that the two ends of the lower mounting rod can be balanced and synchronously approach or move away from the upper mounting rod, which is more stable than unilateral lifting.

[0033] In some embodiments, two detection members may be further included. A sensing rod is fixed on the transmission rod, and the detection member is located on the side of the sensing rod.

[0034] When the sensing rod triggers a detection element, the first driving component stops working, and the upper pressing wheel and the lower pressing wheel move away from each other so that the paper can pass between the upper pressing wheel and the lower pressing wheel without deformation.

[0035] When the sensing rod triggers another detection component, the upper pressing wheel and the lower pressing wheel press the paper to deform.

[0036] Therefore, when loading is required, the driving shaft of the first driving component rotates in the opposite direction, the transmission rod rotates, the rotating transmission rod drives the sensing rod to swing, and the mounting block slides up and down on the slideway. When the sensing rod triggers one of the detection parts, the first driving component stops working. At this time, the upper pressing wheel and the lower pressing wheel are separated, and the paper can pass between the upper pressing wheel and the lower pressing wheel without deformation. Then, the paper can be easily passed between the upper pressing wheel and the lower pressing wheel. Then the driving shaft of the first driving component continues to rotate in the opposite direction, the transmission rod rotates, and the rotating transmission rod drives the sensing rod to swing, the mounting block slides upward on the slideway, and the lower pressing wheel approaches the upper pressing wheel. When the sensing rod triggers another detection part, the first driving component stops working. At this time, the upper pressing wheel and the lower pressing wheel press the paper, and then the bubble pressing machine performs the normal process of producing bubble paper.

[0037] In some embodiments, a guide rod may be provided on the slideway, a spring is sleeved on the guide rod, the end of the guide rod is inserted into the mounting block, one end of the spring presses against the slideway, and the other end of the spring presses against the mounting block. Thus, the mounting block can slide up and down smoothly on the slideway along the guide rod, and the spring on the guide rod facilitates the rapid resetting of the mounting block and keeps the force on the mounting block on the slideway stable.

[0038] In some embodiments, the first driving component may include a cylinder, the piston rod of the cylinder drives the mounting block to slide on the slideway.

[0039] or

[0040] It can include a feeding motor, a gear, and a rack. The rack is installed on the mounting block along the length direction of the slideway, and the gear is installed on the output shaft of the feeding motor, and the gear is meshed with the rack.

[0041] Therefore, the sliding movement of the mounting block on the slideway can also be driven by a cylinder, and the movement of the mounting block is driven by the extension and contraction of the piston rod of the cylinder. Alternatively, the gear driven by the feed motor rotates, the rack meshes with the gear, the gear drives the rack to move, and the mounting block and the rack move synchronously to realize the movement of the mounting block on the slideway.

[0042] In some embodiments, an upper guide plate and a lower guide plate may be further included, the upper guide plate and the lower guide plate are arranged up and down, the space between the upper guide plate and the lower guide plate includes an entrance portion and a paper pre-shrinkage passage portion that are interconnected, and the paper pre-shrinkage passage portion is located between the upper mounting rod and the lower mounting rod. Thus, the entrance portion between the upper guide plate and the lower guide plate is used for paper to enter and load, and the paper pre-shrinkage passage portion can guide the transportation of the paper.

[0043] In some embodiments, the height of the paper pre-shrinkage passage portion may be greater than the height of the entrance portion. Thus, when the paper passes between the upper mounting rod and the lower mounting rod, the paper will be wrinkled and compressed, and the thickness of the paper will increase. The height of the paper pre-shrinkage passage portion between the upper guide plate and the lower guide plate is greater than the height of the entrance portion, which can provide space for the paper with increased thickness. In addition, the narrow entrance portion can prevent damage caused by human hands reaching in, thereby improving safety.

[0044] In some embodiments, the thickness of at least one upper pressing wheel between the two outermost upper pressing wheels in the length direction of the upper mounting rod is greater than the thickness of the two outermost upper pressing wheels, or

[0045] At least one lower pressing wheel between the two outermost lower pressing wheels in the length direction of the lower mounting rod has a thickness greater than that of the two outermost lower pressing wheels.

[0046] Therefore, in this case, at least one upper pressing wheel between the two outermost upper pressing wheels or at least one lower pressing wheel between the two outermost lower pressing wheels can serve as the key area for pre-shrinkage in the width direction of the paper, thereby ensuring the overall effect of pre-shrinkage in the width direction of the paper.

[0047] In some embodiments, the ratio of the spacing between the upper pressing wheel and the nearest lower pressing wheel in the length direction of the upper mounting rod to the longitudinal dimension of the overlapping portion of the projections of the upper pressing wheel and the nearest lower pressing wheel in the length direction of the upper mounting rod can be 0.3 to 0.9. Thus, this arrangement can ensure the pre-shrinkage effect of the paper in the width direction, making full preparations for the subsequent bubble forming of the paper.

[0048] In some embodiments, the angle between the connecting line between the end point of the bottom of the upper pressing wheel close to the nearest lower pressing wheel and the end point of the top of the lower pressing wheel close to the upper pressing wheel and the end face of the upper pressing wheel can be 10-45°. Thus, this arrangement can ensure the pre-shrinkage effect of the paper in the width direction, making full preparations for the subsequent bubble forming of the paper.

[0049] In some embodiments, the spacing between the two outermost upper pressing wheels can be 290-310 mm, or the spacing between the two outermost lower pressing wheels can be 290-310 mm. Thus, this spacing setting can be compatible with the pre-shrinkage treatment of paper materials with a width of 300 mm, 400 mm, and 500 mm, all with good pre-shrinkage effects, and the paper materials are not easily torn during embossing.

[0057] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0059] Figures 1 to 7 The structure of a bubble pressing machine according to one embodiment of the utility model is schematically shown.

[0060] refer to Figures 1 to 7 A bubble pressing machine with a feeding structure includes a bubble pressing mechanism, an upper mounting rod 101 and a lower mounting rod 102.

[0061] In addition, the bubble pressing machine may further include a first driving component 300, a transmission mechanism, a detection component 500, an upper guide plate 800, a lower guide plate 900 and a bracket.

[0062] The bubble pressing mechanism is used to emboss the paper material to form bubble paper and convey the bubble paper to the downstream direction. When the paper material needs to be loaded, the upper mounting rod 101 and the lower mounting rod 102 move away from each other, and then the paper material can be easily passed through; after the loading is completed, the upper mounting rod 101 and the lower mounting rod 102 move closer to each other, and then the bubble pressing machine performs the normal process of producing bubble paper.

[0063] refer to Figure 1 and Figure 2 The bracket includes a left bracket 1300 and a right bracket 1400 arranged longitudinally. The two ends of the upper mounting rod 101 are respectively mounted on the left bracket 1300 and the right bracket 1400 through a bearing, and the upper mounting rod 101 can rotate on the bracket; the two ends of the lower mounting rod 102 are respectively mounted on two mounting blocks 406 of the transmission mechanism through a bearing (described in detail later), and the lower mounting rod 102 can rotate on the bracket. In some embodiments, the upper mounting rod 101 and the lower mounting rod 102 may not rotate, but the friction between the upper mounting rod 101 and the lower mounting rod 102 and the paper material will increase.

[0064] Slideways 407 are provided on both the left bracket 1300 and the right bracket 1400 , and the two mounting blocks 406 slide and move in the slideways 407 on both sides respectively.

[0065] refer to Figure 5, an upper pressing wheel 1013 is fixed on the upper mounting rod 101, and the upper pressing wheel 1013 rotates synchronously with the upper mounting rod 101, and a lower pressing wheel 1023 is fixed on the lower mounting rod 102, and the lower pressing wheel 1023 rotates synchronously with the lower mounting rod 102. The upper pressing wheel 1013 and the lower pressing wheel 1023 can exert pressure on the paper passing through the upper mounting rod 101 and the lower mounting rod 102 in the longitudinal direction, so that the paper is deformed and a pre-shrinking effect is produced in the width direction. Or the upper pressing wheel 1013 and the lower pressing wheel 1023 are both installed through bearings, so that the upper pressing wheel 1013 and the lower pressing wheel 1023 can rotate. The above arrangement can reduce the friction between the paper and the upper pressing wheel 1013 and the lower pressing wheel 1023.

[0066] refer to Figure 5 In this embodiment, the number of upper pressing wheels 1013 is four, and the number of lower pressing wheels 1023 is six. The four upper pressing wheels 1013 are distributed on the upper mounting rod 101, and the six lower pressing wheels 1023 are distributed on the lower mounting rod 102. At least part of the upper pressing wheels 1013 and at least part of the lower pressing wheels 1023 are staggered in the length direction of the gap between the upper mounting rod 101 and the lower mounting rod 102. Specifically, the middle position of the upper mounting rod 101 or the lower mounting rod 102 is the midline, and the upper pressing wheels 1013 and the lower pressing wheels 1023 on the left side of the midline are staggered in the horizontal direction. The upper pressing wheel 1013 and the lower pressing wheel 1023 on the right side of the center line are also staggered in the horizontal direction. In this way, when the paper passes between the upper mounting rod 101 and the lower mounting rod 102, under the action of the upper pressing wheel 1013 and the lower pressing wheel 1023, the width direction of the paper (the length direction of the upper mounting rod 101 and the lower mounting rod 102) will be wrinkled and compressed to form a wave shape, shortening the size of the paper in the width direction, achieving pre-contraction of the paper in the width direction, thereby reducing the probability of the paper being torn when it is subsequently embossed by the bubble pressing mechanism. In other embodiments, the number and distribution of the upper pressing wheel 1013 and the lower pressing wheel 1023 can be adjusted according to the width of the paper and the pre-contraction requirements of the paper.

[0067] refer to Figure 5 , the upper pressing wheel 1013 and the lower pressing wheel 1023 are in the length direction of the gap between the upper mounting rod 101 and the lower mounting rod 102 ( Figure 5 The projections on the left and right directions (shown in the figure) overlap, so that the upper pressing wheel 1013 can press the paper material in the direction of the lower pressing wheel 1023, and the lower pressing wheel 1023 can press the paper material in the direction of the upper pressing wheel 1013, so that the paper material is wrinkled. When the upper mounting rod 101 and the lower mounting rod 102 are separated from each other by a certain distance, the upper pressing wheel 1013 and the lower pressing wheel 1023 are spaced apart in the length direction ( Figure 5 The projections in the left and right directions (as shown) may not overlap, so that the paper can be easily passed between the upper mounting rod 101 and the lower mounting rod 102 during loading.

[0068] refer to Figure 5 In this embodiment, the thickness of the two outermost upper pressing wheels 1013 in the length direction of the upper mounting rod 101 is less than the thickness of the two middle upper pressing wheels 1013. In this case, the two upper pressing wheels 1013 between the two outermost upper pressing wheels 1013 can be used as the key area for pre-shrinking in the width direction of the paper material, thereby ensuring the overall effect of pre-shrinking the paper material in the width direction. In other embodiments, it can also be that the thickness of the two outermost lower pressing wheels 1023 in the length direction of the lower mounting rod 102 is less than the thickness of the other lower pressing wheels 1023. In this case, the other lower pressing wheels 1023 between the two outermost lower pressing wheels 1023 can be used as the key area for pre-shrinking in the width direction of the paper material, thereby ensuring the overall effect of pre-shrinking the paper material in the width direction.

[0069] refer to Figure 6 The ratio of the spacing dimension L1 between the upper pressing wheel 1013 and the nearest lower pressing wheel 1023 in the length direction of the upper mounting rod 101 and the longitudinal dimension L2 (compression depth of the paper) of the overlapping part of the projections of the upper pressing wheel 1013 and the nearest lower pressing wheel 1023 in the length direction of the upper mounting rod 101 is 0.3 to 0.9. This setting can ensure the pre-shrinkage effect of the paper in the width direction and make full preparations for the subsequent bubble forming of the paper.

[0070] refer to Figure 6 The angle a between the connecting line 100 between the end point of the lower pressing wheel 1023 at the bottom of the upper pressing wheel 1013 and the end point of the lower pressing wheel 1023 at the top of the upper pressing wheel 1013 and the end face of the upper pressing wheel 1013 is 10 to 45°. This setting can ensure the pre-shrinkage effect of the paper in the width direction and make full preparations for the subsequent bubble forming of the paper.

[0071] refer to Figure 5 In this embodiment, the spacing L3 between the two outermost lower pressing wheels 1012 is 290-310 mm, and this spacing setting is compatible with the pre-shrinkage processing of paper materials with a width of 300 mm, 400 mm, and 500 mm. In other embodiments, the spacing between the two outermost upper pressing wheels 1013 may be 290-310 mm.

[0072] refer to Figure 1 The first driving component 300 can drive the mounting block 406 to move on the slideway 407 to make the lower mounting rod 102 approach or move away from the upper mounting rod 101.

[0073] In some embodiments, the first driving component 300 drives the mounting block 406 to move through the transmission mechanism, that is, the first driving component 300 can drive the lower pressure wheel 1012 on the lower mounting rod 102 to move closer to or away from the upper pressure wheel 1013 of the upper mounting rod 101 through the transmission mechanism.

[0074] refer to Figure 1 and Figure 2 In some embodiments, the transmission mechanism includes a synchronous belt 401, a one-way wheel body 402, a first swing rod 403, a connecting rod 404, a transmission rod 408, two second swing rods 409, and a linkage shaft 405.

[0075] refer to Figures 1 to 3 The bubble pressing mechanism is a pair of bubble pressing rollers 201 distributed up and down and rotating in opposite directions. When the two bubble pressing rollers 201 rotate, they can emboss the paper material so that the surface of the formed paper material presents uneven protrusions and pits, thereby forming bubble paper.

[0076] refer to Figure 1 The first driving component 300 can be a motor, and the driving shaft of the first driving component 300 is inserted in the right bracket 1400. A rotating wheel 3001 is installed on the driving shaft of the first driving component 300. The end of the foam pressing roller 201 located below passes through the right bracket 1400 and the part extending from the right bracket 1400 is installed with a synchronous wheel 2011. The one-way wheel body 402 is installed on the right bracket 1400. The one-way wheel body 402 can be composed of a one-way bearing + a ring body. The ring body has a built-in one-way bearing, and the inner ring of the one-way bearing is installed with a shaft component. The shaft component is installed on the right bracket 1400 through a bearing, and the one-way wheel body 402 can only rotate in one direction. Figure 1 In the one-way wheel body 402, when the ring body of the one-way wheel body 402 rotates clockwise, the shaft component of the one-way wheel body 402 does not rotate, and when the ring body of the one-way wheel body 402 rotates counterclockwise, the shaft component of the one-way wheel body 402 also rotates counterclockwise. The one-way wheel body 402 is similar to the ratchet structure on the rear wheel of a self-supporting bicycle. In this embodiment, the structure of the synchronous wheel 2011 is the same as that of the one-way wheel body 402, except that the one-way rotation direction is opposite, and the synchronous belt 401 is sleeved on the rotating wheel 3001, the synchronous wheel 2011, and the one-way wheel body 402; when the driving shaft of the first driving component 300 rotates in the forward direction, the rotating wheel 3001 drives the synchronous belt 401 to transmit clockwise, and the synchronous belt 401 drives the synchronous wheel 2011 to rotate clockwise.

When the sensing rod 4081 triggers the upper detection member 500, the first driving component 300 stops working. At this time, the lower mounting rod 102 is separated from the upper mounting rod 101 so that the paper can pass between the upper mounting rod 101 and the lower mounting rod 102 without deformation. At this time, it is used for feeding. When the sensing rod 40 When the detection member 500 below is triggered by the first driving member 300, the lower mounting rod 102 is close to the upper mounting rod 101 so that the lower mounting rod 102 and the upper mounting rod 101 clamp the paper material and convey it; when feeding is required, the driving shaft of the first driving member 300 rotates in the opposite direction, the transmission rod 408 rotates, and the rotating transmission rod 408 drives the sensing rod 4081 to swing, and the mounting block 406 slides up and down on the slide 407. When the sensing rod 4081 triggers the detection member 500 above, the first driving member 300 stops working, and the mounting block 406 moves up and down on the slide 407. The paper material is then easily passed through between the upper mounting rod 101 and the lower mounting rod 102, and then the driving shaft of the first driving component 300 continues to rotate in the opposite direction, the transmission rod 408 rotates, and the rotating transmission rod 408 drives the sensing rod 4081 to swing, and the mounting block 406 slides upward on the slideway 407.

The upper guide plate 800 is formed with a plurality of first through grooves for the upper pressing wheel 1013 to penetrate, and the lower guide plate 900 is formed with a plurality of second through grooves for the lower pressing wheel 1023 to penetrate, and the paper pre-shrinkage passage portion 892 can guide the conveyance of the paper, and the entrance portion 891 between the upper guide plate 800 and the lower guide plate 900 is for the paper to enter and realize the loading; refer to Figure 4 The height of the paper pre-shrinkage passage 892 is greater than the height of the entrance 891. When the paper passes between the upper mounting rod 101 and the lower mounting rod 102, the paper will be wrinkled and compressed, and the thickness of the paper will increase. The height of the paper pre-shrinkage passage 892 between the upper guide plate 800 and the lower guide plate 900 is greater than the height of the entrance 891, which can provide space for the paper with increased thickness. Moreover, the narrow entrance 891 can prevent injuries caused by human hands reaching in, thereby improving safety.

[0085] refer to Figure 1 and Figure 2 In the bubble pressing machine of the present invention, when the paper passes between the upper mounting rod 101 and the lower mounting rod 102, under the action of the upper pressing wheel 1013 on the upper mounting rod 101 and the lower pressing wheel 1023 on the lower mounting rod 102, the width direction of the paper will be wrinkled and compressed to form a wave shape, shortening the size of the paper in the width direction, realizing pre-shrinkage of the paper in the width direction, thereby reducing the probability of the paper being torn when it is subsequently embossed and formed by a pair of bubble pressing rollers 201. The driving shaft of the first driving component 300 rotates forward, and the two bubble pressing rollers 201 rotating in opposite directions can emboss and form the paper, so that the surface of the formed paper presents uneven protrusions and pits, thereby forming bubble paper; when feeding is required, the driving shaft of the first driving component 300 rotates in the opposite direction (such as through a steering switch) Control), the synchronous belt 401 drives the shaft component of the one-way wheel body 402 to rotate, the shaft component of the one-way wheel body 402 drives the first swing rod 403 to rotate, the rotation of the first swing rod 403 drives one end of the connecting rod 404 to move, the other end of the connecting rod 404 drives a linkage shaft 405 to move, the moving linkage shaft 405 drives a mounting block 406 to slide up and down on a slide 407, synchronously, the linkage shaft 405 drives a transmission rod 408 to rotate through a second swing rod 409, the transmission rod 408 drives another linkage shaft 405 to move through another second swing rod 409, the moving linkage shaft 405 drives another mounting block 406 to slide up and down on another slide 407, thereby achieving balanced and synchronous approach or distance between the two ends of the lower mounting rod 102 to or from the upper mounting rod 101.

[0086] When the mounting block 406 slides downward on the slideway 407, when the sensing rod 4081 triggers the detection member 500 above, the first driving component 300 stops working. At this time, the distance between the lower mounting rod 102 and the upper mounting rod 101 reaches the maximum. Then, the paper can be easily passed between the upper pressing wheel 1013 on the upper mounting rod 101 and the lower pressing wheel 1023 on the lower mounting rod 102, and the paper is fed between the two foam pressing rollers 201. After the loading is completed, the driving shaft of the first driving component 300 continues to rotate in the opposite direction, and the mounting block 406 is on the slideway. 407 slides upward, when the sensing rod 4081 triggers the detection member 500 below, the first driving component 300 stops working, at which time the distance between the lower mounting rod 102 and the upper mounting rod 101 reaches the minimum, the upper pressing wheel 1013 on the upper mounting rod 101 and the lower pressing wheel 1023 on the lower mounting rod 102 clamp the paper, and the lower mounting rod 102 completes the reset, that is, the loading is completed, and subsequently the driving shaft of the first driving component 300 can be rotated in the forward direction (such as controlled by a steering switch) to enable the foam pressing roller 201 to emboss the paper.

[0087] In other embodiments, the driving method of the movement of the mounting block 406 on the slide 407 can also be independent of the driving structure of the foam pressing roller, and can be the following two methods, although of course it is not limited to these two methods.

[0088] The first one:

[0089] The first driving component 300 includes a cylinder, which is arranged on a bracket. The piston rod of the cylinder drives the mounting block 406 to slide on the slideway 407, so as to achieve the approach and separation of the upper pressing wheel 1013 and the lower pressing wheel 1023.

[0090] Second type:

[0091] The first driving component 300 includes a feed motor, a gear, and a rack. The feed motor is mounted on a bracket, and the rack is mounted on the mounting block 406 along the length direction of the slideway 407. The gear is mounted on the output shaft of the feed motor, and the gear is meshed with the rack. When the mounting block 406 needs to be raised or lowered, the feed motor drives the gear to rotate, and the gear drives the rack to move. The rack moves synchronously with the mounting block 406, so that the mounting block 406 slides on the slideway 407, thereby achieving the approach and distance between the upper pressing wheel 1013 and the lower pressing wheel 1023.

[0092] The bubble pressing machine of the utility model is simple and convenient for feeding paper materials, and there is no need to insert the paper materials little by little between the required rings on the two mounting rods, and the paper materials are not easily deviated from the conveying path.
