Description

Technical Field

[0001] The utility model relates to the field of waste paper processing equipment, in particular to a waste paper bale dispersing device. Background Art

[0002] For the convenience of transportation and stacking, waste paper in waste paper packing stations is generally pressed into rectangular waste paper bales (roughly sized 2 m × 1.3 m × 1.2 m) by a baler. During baling, the pressure is relatively high, and the waste paper is closely attached to each other and not easily dispersed. However, for enterprises that use waste paper for subsequent processing, if they need to comprehensively detect the quality of waste paper (such as measuring moisture at multiple points, picking out impurities, quality grading, etc.), they need to completely disperse the waste paper bales. Currently, the ropes of the waste paper bales are first cut, and then the waste paper bales are dropped from a height (4 - 5 meters) by a forklift or the like for unpacking. Generally, one drop is not sufficient to completely disperse the bales, and such operations need to be carried out multiple times. The required working area is relatively large, and the efficiency is low. For on-site operators, the working environment in terms of noise, dust, and safety is relatively poor.

Specific embodiments

[0027] Typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various variations in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the description of the positions of these elements changes, then the indication of these directions also changes accordingly.

[0029] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0030] Refer to Figures 1 - 3, a waste paper bale disassembling device, including a conveying mechanism 1, a strap cutting mechanism 4, a waste paper bale shredding assembly 2 and a disassembling mechanism 5. The strap cutting mechanism 4, the waste paper bale shredding assembly 2 and the disassembling mechanism 5 are arranged in sequence along the conveying direction of the conveying mechanism 1. When the waste paper bale 9 moves under the conveyance of the conveying mechanism 1, the strap on the waste paper bale 9 is cut off by the strap cutting mechanism 4, and then the waste paper bale 9 is shredded by the waste paper bale shredding assembly 2 to achieve preliminary unpacking. Then, the waste paper bale 9 that has been preliminarily unpacked is disassembled by the disassembling mechanism 5, so that the waste paper bale 9 is completely disassembled, facilitating subsequent detection of the quality of the waste paper. The detection of the quality of the waste paper includes water measurement, impurity picking, quality grading, etc. During the unpacking process of the waste paper bale 9, each step is automated, eliminating the need for on-site operation by workers, reducing the labor intensity of the workers, improving work efficiency, and achieving better unpacking effects.

[0031] Specifically, the conveying mechanism 1 can be a roller conveying mechanism, a plate conveying mechanism or a belt conveying mechanism. In addition to being used to convey the waste paper bale 9, the conveying plane 11 of the conveying mechanism 1 is also used to support the waste paper bale 9 when the waste paper bale shredding assembly 2 shreds the waste paper bale 9, that is, the conveying plane 11 of the conveying mechanism 1 forms a working platform for supporting the waste paper bale 9.

[0032] Among them, the working motor of the conveying mechanism 1 is a stepping motor. The stepping motor drives the waste paper bale 9 to move a certain distance and then stops. Then, the waste paper bale shredding assembly 2 tears the waste paper bale 9. Then, the stepping motor drives the waste paper bale 9 to move a certain distance again, and so on, until the waste paper bale 9 is completely shredded. Moreover, the rotation angle of the stepping motor is adjustable, that is, the distance that the waste paper bale 9 moves each time is adjustable, so that the amount of waste paper shredded each time can be adjusted according to the tearing difficulty of the waste paper bale 9. And, the conveying structure 1 can also be omitted. The waste paper bale 9 can be placed on the conveying mechanism 1, and the waste paper bale 9 can also be disassembled by the strap cutting mechanism 4, the waste paper bale shredding assembly 2 and the disassembling mechanism 5.

[0033] The waste paper bale shredding assembly 2 includes a bracket 21, a first driving mechanism 22, a second driving mechanism 23 and a plug rod 24. The bracket 21 is arranged on the conveying path of the conveying mechanism 1 and is connected to the frame of the conveying mechanism 1. The first driving mechanism 22 and the second driving mechanism 23 are connected to the bracket 21, and the plug rod 24 is connected to the first driving mechanism 22 and the second driving mechanism 23. The first driving mechanism 22 can drive the plug rod 24 to move in a first direction close to the conveying mechanism 1, so that the plug rod 24 is inserted into the waste paper bale 9 located on the conveying mechanism 1. The first direction can be the vertical direction or the width direction of the conveying mechanism 1. Preferably, the plug rod 24 is inserted into the waste paper bale 9 along a direction perpendicular to the waste paper bale 9 on the conveying mechanism 1.

[0034] The second driving mechanism 23 can drive the inserting rod 24 to move in the second direction, and the second direction forms an angle with the first direction, so that when the inserting rod 24 moves in the second direction, it can tear the waste paper bale 9. With such a setting, the inserting rod 24 can disperse the waste paper bale 9 by tearing. The second direction is the conveying direction of the conveying mechanism 1, and the second direction can be a horizontal direction or an angle with the horizontal plane. In Figure 1 In the illustrated embodiment, the conveying direction of the conveying mechanism 1 is preferably a horizontal direction, and the first direction is perpendicular to the second direction, that is, the angle between the second direction and the first direction is 90°. In other embodiments, the angle between the second direction and the first direction can also be other angles.

[0035] The bracket 21 includes columns 211 and a cross beam 212. There are two columns 211, and the two columns 211 are respectively fixed on both sides of the frame of the conveying mechanism 1. The columns 211 extend upward above the conveying mechanism 1, and the cross beam 212 is arranged at the upper ends of the columns 211 and is located above the conveying plane of the conveying mechanism 1. With such a setting, the bracket 21 forms a gantry structure with stable structure. In other embodiments, the bracket 21 can also be in an inverted "L" shape or other shaped structures.

[0036] The first driving mechanism 22 is a telescopic structure, a crank - connecting rod structure, a rack - and - pinion structure or a lead screw structure. Among them, the telescopic structure can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. When the first driving mechanism 22 is one of the crank - connecting rod structure, the rack - and - pinion structure and the lead screw structure, it can be driven by a hydraulic motor or an electric motor. The fixed end of the first driving mechanism 22 is fixed on the bracket 21, and the moving end of the first driving mechanism 22 can move in the first direction, and thus can drive the inserting rod 24 to move in the first direction.

[0037] The second driving mechanism 23 is a telescopic structure, a crank - connecting rod structure, a rack - and - pinion structure or a lead screw structure. Among them, the telescopic structure can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. When the second driving mechanism 23 is one of the crank - connecting rod structure, the rack - and - pinion structure and the lead screw structure, it can be driven by a hydraulic motor or an electric motor. The fixed end of the second driving mechanism 23 is connected to the moving end of the first driving mechanism 22, so that the first driving mechanism 22 can drive the second driving mechanism 23 and the inserting rod 24 to move together. The upper end of the inserting rod 24 is connected to the moving end of the second driving mechanism 23, the lower end of the inserting rod 24 is a suspended end, and the moving end of the second driving mechanism 23 can move in the second direction, and thus can drive the inserting rod 24 to move in the second direction.

[0038] In Figure 1 and Figure 2In the illustrated embodiment, the first direction is perpendicular to the conveying plane 11 of the conveying mechanism 1, that is, the first direction is the vertical direction. That is to say, the inserting rod 24 is located above the conveying mechanism 1. When the first driving mechanism 22 drives the inserting rod 24 to move downward, the inserting rod 24 can be inserted into the waste paper bale 9 located below it. In this embodiment, the inserting rod 24 is inserted into the waste paper bale 9 from top to bottom. When the inserting rod 24 is inserted into the waste paper bale 9, the direction of the pressure exerted by the inserting rod 24 on the waste paper bale 9 is exactly opposite to the direction of the supporting force exerted by the conveying mechanism 1 on the waste paper bale 9, so that when the inserting rod 24 is inserted into the waste paper bale 9, there is no need to provide a limiting structure on the side of the waste paper bale 9 away from the inserting rod 24 to prevent the waste paper bale 9 from moving.

[0039] In an embodiment, the first direction can also be the width direction of the conveying mechanism 1, that is, the inserting rod 24 is located on the side of the conveying mechanism 1. When the first driving mechanism 22 drives the inserting rod 24 to move, the inserting rod 24 is inserted into the waste paper bale 9 from the side of the waste paper bale 9. In this embodiment, a baffle structure can be provided on the side of the conveying mechanism 1 away from the inserting rod 24, and the baffle structure is used to support the waste paper bale 9 to prevent the waste paper bale 9 from moving along the width direction of the conveying mechanism 1 when the inserting rod 24 is inserted into the waste paper bale 9. It is also possible to provide inserting rods 24 on both sides in the width direction of the conveying mechanism 1. When the inserting rods 24 are inserted into the waste paper bale 9, the inserting rods 24 on both sides in the width direction of the conveying mechanism 1 move towards each other, so that the waste paper bale 9 is in force balance in the width direction of the conveying mechanism 1.

[0040] In an alternative embodiment, the positions of the first driving mechanism 22 and the second driving mechanism 23 can be swapped. That is, the second driving mechanism 23 is connected to the bracket 21, the first driving mechanism 22 is connected to the movable end of the second driving mechanism 23, and the inserting rod 24 is connected to the movable end of the first driving mechanism 22.

[0041] Refer to Figures 4 - 6 , specifically, the inserting rod 24 is provided with a guiding inclined surface 241 on the side facing the second direction, that is, the guiding inclined surface 241 is provided on the side of the inserting rod 24 close to the dispersing mechanism 5. The guiding inclined surface 241 is connected to the bottom surface of the inserting rod 24, and the size of the inserting rod 24 at the lower end of the guiding inclined surface 241 is smaller than the size of the inserting rod 24 at the upper end of the guiding inclined surface 241. That is to say, the inserting rod 24 forms a wedge shape, and the inclined surface of the inserting rod 24 is provided on the side facing the dispersing mechanism 5. When the inserting rod 24 is inserted into the waste paper bale 9, the position with a smaller size at the lower end of the inserting rod 24 contacts the waste paper bale 9 first, and then as the depth of insertion of the inserting rod 24 increases, the position with a larger size on the inserting rod 24 can expand the waste paper bale 9, improving the tearing effect of the waste paper bale 9. Among them, when multiple waste paper bales 9 are continuously conveyed, the side of the waste paper bale 9 away from the dispersing mechanism 5 contacts the adjacent waste paper bale 9. In this application, the direction in which the waste paper bale 9 is expanded is the side close to the dispersing mechanism 5, and there is no support on this side of the waste paper bale 9, so it is easier to be torn.

[0042] Refer toFigure 2 In one embodiment, multiple inserting rods 24 are arranged at intervals in the width direction of the conveying mechanism 1. The multiple inserting rods 24 are fixedly connected to the movable end of the second driving mechanism 23, so that the second driving mechanism 23 can drive the multiple inserting rods 24 to move simultaneously, and the multiple inserting rods 24 tear the waste paper bale 9 simultaneously, improving the tearing efficiency of the waste paper bale 9. In other embodiments, only one inserting rod 24 may be arranged.

[0043] Refer to Figures 7 - 11 In one embodiment, multiple groups of inserting rods 24 are arranged at intervals in the second direction. The waste paper bale dispersing device further includes a connecting rod 25. The connecting rod 25 is movably connected to all the inserting rods 24 to realize the linkage connection between the groups of inserting rods 24, so that when one group of inserting rods 24 moves, the other groups of inserting rods 24 also move together. The second driving mechanism 23 is connected to one group of inserting rods 24. When the second driving mechanism 23 drives the inserting rods 24 to move, the connecting rod 25 can swing to change the distance between adjacent two groups of inserting rods 24, improving the tearing efficiency of the waste paper bale 9 and also improving the tearing effect on the waste paper bale 9.

[0044] Furthermore, multiple connecting rods 25 are arranged. The multiple connecting rods 25 form a parallelogram structure. Adjacent two groups of inserting rods 24 are rotatably connected to the diagonals of the parallelogram structure. The connecting rod 25 also extends along the outer side of the parallelogram structure and is slidably connected to the corresponding inserting rods 24, so that the groups of inserting rods 24 move synchronously, and the distance between adjacent two groups of inserting rods 24 always remains equal. Moreover, there are multiple connection points between each group of inserting rods 24 and the connecting rod 25, improving the stability of the inserting rods 24 when the second driving mechanism 23 drives the inserting rods 24 to move.

[0045] In Figure 10 and Figure 11 the shown embodiment, from left to right are the first group of inserting rods, the second group of inserting rods, the third group of inserting rods... Under the drive of the second driving mechanism 23, if the relative moving distance of the first group of inserting rods 24 is S, then the moving distance of the second group of inserting rods 24 is 2S, that is, the relative moving distance between the first group of inserting rods 24 and the second group of inserting rods 24 is also S, and the moving distance of the third group of inserting rods 24 is 3S, that is, the relative moving distance between the second group of inserting rods 24 and the third group of inserting rods 24 is also S, and so on. With such a setting, a tearing effect is achieved at each group of inserting rods 24, improving the tearing efficiency of the waste paper bale 9 and also improving the tearing effect on the waste paper bale 9.

[0046] At the upper end of each set of inserting rods 24, there is a vertically arranged slide rail 28. Two sliders 29 are slidably connected to the slide rail 28. The two sliders 29 are respectively rotationally connected to the positions where two connecting rods 25 extend along the outer side of the parallelogram structure. The connection position between the inserting rod 24 and the parallelogram structure is located between the two sliders 29. When the second driving mechanism 23 drives the inserting rod 24 to move, the two sliders 29 move towards or away from each other, and the two sliders 29 always remain in the same vertical plane. Therefore, the two sliders 29 play an auxiliary limiting role on the inserting rod 24, so that the inserting rod 24 will not tilt or shake.

[0047] In Figure 10 In the illustrated embodiment, the position of the left slide rail 28 is fixed, and the connecting rod 25 is connected to the slide rail 28. During the swinging process of the connecting rod 25, the connection point position between the connecting rod 25 and the left slide rail 28 remains unchanged. Furthermore, when the inserting rod 24 moves and then resets, the position of the inserting rod 24 is consistent with the set position.

[0048] In one embodiment, multiple inserting rods 24 are arranged at intervals along the width direction of the conveying mechanism 1 in each group to increase the number of inserting rods 24 and improve the tearing efficiency of the waste paper bale 9. In other embodiments, the number of inserting rods 24 in each group of inserting rods 24 can also be one.

[0049] Preferably, the waste paper bale dispersing device further includes a first guiding structure 26. The first guiding structure 26 is connected to the support 21, and the length direction of the first guiding structure 26 extends along the first direction. The movable end of the first driving mechanism 22 is also slidably connected to the first guiding structure 26, so that the first guiding structure 26 plays a guiding role in the up and down movement of the inserting rod 24, making the up and down movement of the inserting rod 24 more stable.

[0050] In one embodiment, the first guiding structure 26 can be a guide rail-slider structure, where the guide rail is fixed on the column 211 of the support 21, the slider is slidably connected to the guide rail, and is connected to the movable end of the first driving mechanism 22. In other embodiments, the first guiding structure 26 is a guiding rod structure. A guiding hole is provided on the cross beam 212 of the support 21. The movable end of the first driving mechanism 22 is fixedly connected to the guiding rod. The guiding rod passes through the guiding hole, and the diameter of the guiding rod corresponds to that of the guiding hole, so that the guiding hole plays a guiding role in the movement of the guiding rod, making the up and down movement of the inserting rod 24 more stable.

[0051] The waste paper bale dispersing device further includes a second guiding structure 27. The second guiding structure 27 is connected to the movable end of the first driving mechanism 22, and the length direction of the second guiding structure 27 extends along the second direction. The inserting rod 24 is also slidably connected to the second guiding structure 27, so that when the second driving mechanism 23 drives the inserting rod 24 to move along the second direction, the second guiding structure 27 plays a guiding role in the inserting rod 24, making the movement of the inserting rod 24 more stable.

[0052] Refer to again Figures 1 - 3 The waste paper bale disassembling device further includes a bale pressing mechanism 3, the bale pressing mechanism 3 is connected to the bracket 21, and the bale pressing mechanism 3 is arranged upstream of the inserting rod 24 along the conveying direction of the conveying mechanism 1. That is, the bale pressing mechanism 3 is arranged on the side of the inserting rod 24 close to the strap cutting mechanism 4, and the bale pressing mechanism 3 can press on the waste paper bale 9. Before the second driving mechanism 23 drives the inserting rod 24 to move in the second direction, the bale pressing mechanism 3 presses the waste paper bale 9 tightly on the conveying plane of the conveying mechanism 1, so that when the second driving mechanism 23 drives the inserting rod 24 to tear the waste paper bale 9, the un-torn part of the waste paper bale 9 is pressed tightly by the bale pressing mechanism 3 and does not move, and the un-torn part of the waste paper bale 9 moves along with the inserting rod 24 to achieve the tearing effect.

[0053] In one embodiment, the bale pressing mechanism 3 includes a pressing rod 32 and an elastic member 31. The upper end of the pressing rod 32 is slidably connected to the movable end of the first driving mechanism 22, and the pressing rod 32 can slide relative to the movable end of the first driving mechanism 22 in the first direction. A limiting member protruding circumferentially is provided at the lower end of the pressing rod 32. The elastic member 31 is sleeved on the pressing rod 32, and both ends of the elastic member 31 in the elastic direction are in contact with the first driving mechanism 22 and the limiting member respectively. When the first driving mechanism 22 drives the inserting rod 24 to move downward, the pressing rod 32 also descends. Until the ground of the pressing rod 32 contacts the waste paper bale 9, the first driving mechanism 22 drives the inserting rod 24 to continue moving downward. At this time, the elastic member 31 is compressed to store energy and presses the waste paper bale 9 tightly. When the first driving mechanism 22 drives the inserting rod 24 to move upward, the elastic member 31 releases elastic potential energy to reset the pressing rod 32. Among them, the setting of the pressing rod 32 can avoid the bending of the elastic member 31 and the reduction of the pressing effect.

[0054] In other embodiments, the length of the elastic member 31 extends in the first direction. The upper end of the elastic member 31 is fixed on the first driving mechanism 22, and the lower end of the elastic member 31 is a free end. When the first driving mechanism 22 drives the inserting rod 24 to move downward, the lower end of the elastic member 31 presses on the waste paper bale 9 and presses the waste paper bale 9 tightly. In this embodiment, the pressing rod 32 may not be provided.

[0055] Preferably, the elastic member 31 is a compression spring.

[0056] In one embodiment, the bale pressing mechanism 3 is a telescopic member. The fixed end of the telescopic member is connected to the bracket 21 or the movable end of the first driving mechanism 22, and the movable end of the telescopic member can extend in the first direction. Before the second driving mechanism 23 drives the inserting rod 24 to move along the conveying direction of the conveying mechanism 1, control the movable end of the telescopic member to extend and press on the waste paper bale 9. When the second driving mechanism 23 drives the inserting rod 24 to tear the waste paper bale 9, the un-torn part of the waste paper bale 9 is pressed tightly by the bale pressing mechanism 3 and does not move. Among them, the telescopic member can be a telescopic cylinder or an electric cylinder.

[0057] The band cutting mechanism 4 is arranged on the conveying path of the conveying mechanism 1 and is located upstream of the insertion rod 24. When the waste paper bag 9 passes the position of the band cutting mechanism 4, the band cutting mechanism 4 cuts off the band used to bind the waste paper bag 9, so as not to affect the subsequent tearing and breaking up of the waste paper bag 9.

[0058] exist Figure 1 and Figure 3 In the illustrated embodiment, the band cutting mechanism 4 includes a cutting blade, which is fixed to the base of the conveying mechanism 1. The cutting blade is hook-shaped, and the concave surface of the cutting blade is located on the side of the cutting blade away from the insertion rod 24. When the waste paper bag 9 passes the position of the cutting blade under the conveying mechanism 1, the cutting blade hooks on the band of the waste paper bag 9, thereby cutting off the band of the waste paper bag 9.

[0059] In one embodiment, cutting blades are provided on both sides of the conveying mechanism 1. When the waste paper bag 9 deviates a certain distance in the width direction of the conveying mechanism 1, at least one cutting blade can cut the binding tape.

[0060] In other embodiments, the cutting blade may also be disposed above the conveying mechanism 1. Since the conveying surface of the conveying mechanism 1 supports the waste paper bag 9, the waste paper bag 9 will not deviate in the vertical direction, thereby enabling the cutting blade to accurately cut the bandage.

[0061] The scattering mechanism 5 is arranged at the end of the conveying mechanism 1, that is, downstream of the insertion rod 24, so that after the waste paper bag 9 is shredded by the waste paper bag shredding assembly 2, it continues to be conveyed to the scattering mechanism 5 through the conveying mechanism 1, and the scattering mechanism 5 scatters the waste paper bag 9.

[0062] exist Figure 1 In the embodiment, the scattering mechanism 5 is at the end of the conveying mechanism 1 and is located below the conveying plane of the conveying mechanism 1, so that after the waste paper bag 9 is shredded by the waste paper bag shredding assembly 2, it falls directly on the scattering mechanism 5, making the structure of the waste paper bag scattering device more compact and reducing the overall occupied area of ​​the device.

[0063] In one embodiment, the scattering mechanism 5 is at a predetermined distance from the conveying plane of the conveying mechanism 1 in the vertical direction. When the predetermined distance is set to be relatively large, such as more than 2 meters, gravity is effectively utilized to improve the scattering effect. In other embodiments, the scattering mechanism 5 can be lower than the conveying plane 11.

[0064] The scattering mechanism 5 includes a driving motor and a scattering wheel. The scattering wheel is located below the conveying plane of the conveying mechanism 1 so that the waste paper bag 9 on the conveying mechanism 1 can fall on the scattering wheel. The scattering wheel includes a wheel shaft and a plurality of scattering blades radially arranged on the circumference of the wheel shaft. The driving motor is connected to the wheel shaft of the scattering wheel to drive the scattering wheel to rotate. When the driving motor drives the scattering wheel to rotate, the waste paper falling on the scattering wheel is shredded and scattered by the scattering blades.

[0065] In one embodiment, a dust collecting device is provided outside the scattering mechanism 5, which can absorb and collect the dust raised when the waste paper is scattering to avoid environmental pollution. The dust collecting device can be a bag absorber, an electrode absorber or a centrifugal absorber.

[0066] Specifically, the steps of breaking up the waste paper bag 9 include:

[0067] The waste paper bag 9 is transported by the conveying mechanism 1 , and when the waste paper bag 9 passes through the band cutting mechanism 4 during the transport process, the band cutting mechanism 4 cuts off the band of the waste paper bag 9 .

[0068] The conveying mechanism 1 conveys the waste paper bag 9 to the insertion rod 24. The first driving mechanism 22 drives the insertion rod 24 to insert the waste paper bag 9 along the first direction. When the insertion rod 24 is inserted into the waste paper bag 9, or before the insertion rod 24 is inserted into the waste paper bag 9, the bag pressing mechanism 3 presses the waste paper bag 9 on the upstream side of the insertion rod 24 to prevent the waste paper bag 9 from being torn apart as a whole due to the movement of the insertion rod 24 when the waste paper bag 9 is torn apart later. Preferably, the insertion rod 24 is wedge-shaped, and when the insertion rod 24 is inserted into the waste paper bag 9, the insertion rod 24 will also initially open the waste paper bag 9.

[0069] The second driving mechanism 23 drives the insertion rod 24 to tear the waste paper bag 9 along the second direction to form a small paper bag. When the second driving mechanism 23 drives the insertion rod 24 to move, the insertion rod 24 moves away from the bag pressing mechanism 3, so that the parts of the waste paper bag 9 located on both sides of the insertion rod 24 are separated, and the waste paper bag 9 is torn. The torn part of the waste paper falls on the scattering wheel.

[0070] The driving motor drives the scattering wheel to rotate and scatters the small paper bags that fall on the scattering wheel. During the rotation of the scattering wheel, the collision of the scattering wheel with the small paper bags can scatter the small paper bags, and the scattering wheel is provided with a scattering sheet, which can cut the small paper bags to achieve shredding of the waste paper bag 9.

[0071] Through the cycle of the above steps, the waste paper bag 9 can be automatically scattered in the whole process of scattering the waste paper bag 9, which reduces the labor intensity of workers, improves work efficiency, and has a better scattering effect. Moreover, a waste paper bag 9 can also be torn and scattered in multiple times.

[0072] The waste paper bale breaking-up device of the present application includes a conveying mechanism 1, a bracket 21, a first driving mechanism 22, a second driving mechanism 23 and a plug rod 24. The conveying mechanism 1 conveys the waste paper bale 9 along the second direction, and the conveying plane of the conveying mechanism 1 can support the waste paper bale 9 to form a conveying mechanism 11. The bracket 21 is arranged on the conveying path of the conveying mechanism 1, the first driving mechanism 22 is connected to the bracket 21, the second driving mechanism 23 is connected to the movable end of the first driving mechanism 22, and the plug rod 24 is connected to the movable end of the second driving mechanism 23. Moreover, the plug rod 24 can move in the first direction of the conveying mechanism 1 to insert into the waste paper bale 9 under the drive of the first driving mechanism 22 and the second driving mechanism 23, and can move in the second direction of the conveying path to tear the waste paper bale 9.

[0073] Further, a strap cutting mechanism 4 is provided upstream of the plug rod 24 to cut the straps of the waste paper bale 9. A breaking-up mechanism 5 is provided downstream of the plug rod 24 to further break up the waste paper bale 9 torn by the plug rod 24, improving the bale-breaking effect. Moreover, the whole realizes automatic bale-breaking of the waste paper bale 9, improving work efficiency, improving safety, and reducing the space required for bale-breaking of the waste paper bale 9.
