Description

Technical Field

[0001] The present invention relates to a floating chute structure for buffering paper pad winding and a buffering paper pad winding device. Background Art

[0002] When packing some heavy objects, if the buffering paper pads used for packing are filled less, the buffering paper pads are easily flattened. If the buffering paper pads are filled more, there are certain requirements for the stacking method and quantity of the buffering paper pads, and it is necessary to ensure that the heavy objects are limited in all directions in the box and can be well supported.

[0003] The existing buffering paper pad equipment makes buffering paper pads in sections. These buffering paper pads do not have a good buffering and packing effect during the process of packing heavy objects, and it is necessary for the packing personnel to manually put the buffering paper pads into the carton in a certain arrangement to buffer the packed heavy objects. This method is labor-consuming and the consistency of the buffering effect of the manually stacked buffering paper pads is poor.

[0004] At present, the buffering paper pad winding frame can wind continuous buffering paper pads into a roll, but the diameters of the wound buffering paper pad rolls are basically fixed or only have several specific diameters, with poor applicability and inability to adapt to different carton sizes. Moreover, the tightness of the wound buffering paper pad rolls is also poor, generally looser than expected. Usually, the operator needs to adjust the tightness and then fix it by tape winding. The way of tape winding and fixing is usually: the equipment for pasting the tape pastes the tape on the tail of the paper pad of the buffering paper pad roll. As the buffering paper pad winding frame starts again for a certain time, the tape can be pasted and wound around the outer periphery of the buffering paper pad roll. However, in this way, it is very difficult to ensure the firmness of the tape pasted on the outer periphery of the buffering paper pad roll. If the winding of the buffering paper pad roll is relatively tight, the tape will be firmly pasted on the outer periphery of the buffering paper pad roll. If the winding of the buffering paper pad roll is relatively loose, the tape will be difficult to be firmly pasted on the outer periphery of the buffering paper pad roll, resulting in the buffering paper pad roll being relatively loose and unable to meet the winding requirements.

[0005] Therefore, how to overcome the above technical defects is an urgent technical problem for those skilled in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide a floating chute structure for buffering paper pad winding and a buffering paper pad winding device to solve at least one of the above technical problems.

[0007] According to one aspect of the present invention, there is provided a floating chute structure for buffering paper pad winding, including: A chute; A rotatable rotating shaft, one end of the chute is fixedly arranged on the rotating shaft, When the trough is subjected to an external force, the trough can swing from a horizontal state to a non-horizontal state with the rotating shaft as the swing center; A limit plate fixedly arranged on the rotating shaft; A driving mechanism capable of driving the limit plate to swing with the rotating shaft as the swing center; and A reset component capable of driving the trough to maintain a tendency to swing from a non-horizontal state to a horizontal state with the rotating shaft as the swing center.

[0008] The floating trough structure of the present invention is used in cooperation with a buffer paper pad winding device. The continuous buffer paper pads produced by an external buffer paper pad machine can be conveyed to the buffer paper pad winding device through the trough. The buffer paper pad winding device winds and winds the continuous buffer paper pads. When there is no buffer paper pad on the trough, under the action of the reset component, the trough remains in a horizontal state. When a buffer paper pad roll with a certain diameter is wound on the buffer paper pad winding device, the outer periphery of the buffer paper pad roll will push the trough downward. When the trough is subjected to the acting force of the buffer paper pad roll, the trough swings from a horizontal state to a non-horizontal state with the rotating shaft as the swing center. Since the reset component drives the trough to maintain a tendency to swing from a non-horizontal state to a horizontal state with the rotating shaft as the swing center, during the winding process of the buffer paper pad winding device, the reset component will drive the trough to always be in close contact with the outer periphery of the buffer paper pad roll, ensuring the tightness of the buffer paper pad roll and preventing the buffer paper pad roll from becoming loose during the winding process. When a roll of buffer paper pads is wound up, the adhesive tape mechanism of the buffer paper pad winding device pastes the tape on the tail of the paper pads of the buffer paper pad roll. As the buffer paper pad winding device starts again for a certain period of time, the trough is always in close contact with the tape on the outer periphery of the buffer paper pad roll, thereby ensuring that the tape is firmly pasted and wound around the outer periphery of the buffer paper pad roll and preventing the buffer paper pad roll from coming apart. When it is necessary to remove the wound buffer paper pad roll from the buffer paper pad winding device, the driving mechanism drives the limit plate to swing with the rotating shaft as the swing center, and the limit plate drives the trough to swing synchronously through the rotating shaft, so that the trough is separated from the outer periphery of the buffer paper pad roll. At this time, the wound buffer paper pad roll can be removed. The floating trough structure of the present invention ensures that the trough is in close contact with the outer periphery of the buffer paper pad roll regardless of whether the buffer paper pad roll wound by the buffer paper pad winding device is the minimum diameter or the maximum diameter, that is, the tightness of the buffer paper pad roll wound by the buffer paper pad winding device can be guaranteed from the minimum diameter to the maximum diameter. The diameter of the buffer paper pad roll wound by the buffer paper pad winding device can be changed between the minimum diameter and the maximum diameter, so that the wound buffer paper pad roll can be adapted to different carton sizes and can be better applied to the buffer packaging of heavy objects. The trough can control the tightness of the buffer paper pad roll, ensuring the consistency of the load-bearing capacity of the buffer paper pad roll during the process of packing items, making it more convenient and efficient for operators to pack items, and can ensure that the tape is firmly pasted and wound around the outer periphery of the buffer paper pad roll, preventing the buffer paper pad roll from coming apart.

[0009] In some embodiments, a carrier plate may also be included. The rotating shaft is inserted through the carrier plate, and the rotating shaft can rotate on the carrier plate. The reset component is a tension spring. One end of the tension spring is provided on the carrier plate, and the other end of the tension spring is provided on the limiting plate.

[0010] Thus, the carrier plate can carry the rotating shaft and the material chute. When there is no buffer paper pad on the material chute, under the pulling force of the tension spring, the limiting plate has a tendency to swing around the rotating shaft as the swing center. The limiting plate drives the material chute through the rotating shaft to have a tendency to swing from a non-horizontal state to a horizontal state around the rotating shaft as the swing center, so that the material chute is kept in a horizontal state. When a buffer paper pad roll with a certain diameter is wound on the buffer paper pad winding device, the outer circumference of the buffer paper pad roll will push the material chute downward. When the material chute is subjected to the acting force of the buffer paper pad roll, the material chute will swing from a horizontal state to a non-horizontal state around the rotating shaft as the swing center. During the winding process of the buffer paper pad winding device, under the pulling force of the tension spring, the material chute is always in close contact with the outer circumference of the buffer paper pad roll, ensuring the tightness of the buffer paper pad roll and preventing the buffer paper pad roll from becoming loose during the winding process. When a roll of buffer paper pad is wound up, the adhesive tape mechanism of the buffer paper pad winding device pastes the tape on the tail of the paper pad of the buffer paper pad roll. As the buffer paper pad winding device is restarted for a certain period of time, the material chute is always in close contact with the tape on the outer circumference of the buffer paper pad roll, thereby ensuring that the tape is firmly pasted and wound around the outer circumference of the buffer paper pad roll.

[0011] In some embodiments, an arc-shaped groove may be provided on the limiting plate. The driving mechanism may include a driving device and a connecting rod. One end of the connecting rod is provided on the driving rod of the driving device, and the other end of the connecting rod is accommodated in the arc-shaped groove. The driving device can drive the connecting rod to move along the arc-shaped groove.

[0012] Thus, when the material chute swings from a horizontal state to a non-horizontal state, the material chute drives the limiting plate to swing synchronously through the rotating shaft. The arc-shaped groove on the limiting plate moves along with the connecting rod, that is, the connecting rod moves from the first end of the arc-shaped groove to the second end direction in the arc-shaped groove. The length of the arc-shaped groove can determine the swing angle of the limiting plate and the material chute. After the buffer paper pad roll is wound up, the driving device drives the connecting rod to move in the arc-shaped groove towards the first end of the arc-shaped groove. When the connecting rod moves to the first end of the arc-shaped groove, the connecting rod drives the limiting plate to swing. The limiting plate drives the material chute to swing synchronously through the rotating shaft. The swinging direction of the material chute is still the direction from a horizontal state to a non-horizontal state. Finally, the material chute is separated from the outer circumference of the buffer paper pad roll. At this time, the wound buffer paper pad roll can be taken off. After the wound buffer paper pad roll is taken off, the driving device drives the connecting rod to reset, and the reset component drives the material chute to reset to a horizontal state, preparing for the next winding.

[0013] In some embodiments, the driving device may be an electric push rod.

[0014] Thus, when the trough swings from the horizontal state to the non-horizontal state, the trough drives the limit plate to swing synchronously through the rotating shaft. The arc-shaped groove on the limit plate moves along the connecting rod, that is, the connecting rod moves in the arc-shaped groove from the first end to the second end of the arc-shaped groove. After the buffer paper pad roll is wound up, the push rod of the electric push rod extends. The push rod of the electric push rod drives the connecting rod to move in the arc-shaped groove towards the first end of the arc-shaped groove. When the connecting rod moves to the first end of the arc-shaped groove, the connecting rod drives the limit plate to swing. The limit plate drives the trough to swing synchronously through the rotating shaft, and finally separates the trough from the outer periphery of the buffer paper pad roll. At this time, the wound buffer paper pad roll can be taken off. After the wound buffer paper pad roll is taken off, the push rod of the electric push rod retracts, the connecting rod resets, and the reset component drives the trough to reset to the horizontal state to prepare for the next winding. The electric push rod can quickly separate the trough from the outer periphery of the buffer paper pad roll, and after taking off the wound buffer paper pad roll, the electric push rod can quickly reset the trough to the horizontal state, ensuring the winding efficiency.

[0015] In some embodiments, the driving mechanism may further include a bearing and two clamping plates. The bearing is provided at the other end of the connecting rod. The bearing is accommodated in the arc-shaped groove. The clamping plates are provided with limit grooves. The two clamping plates are respectively provided on both sides of the limit plate. The connecting rod is inserted into one limit groove and can move along the limit groove. The width of the limit groove is smaller than the width of the arc-shaped groove.

[0016] Thus, the connecting rod can move smoothly in the arc-shaped groove through the bearing, optimizing the sliding friction between the connecting rod and the arc-shaped groove into the rolling friction between the bearing and the arc-shaped groove, thereby effectively reducing the friction between the connecting rod and the arc-shaped groove and extending the service life. The two clamping plates can limit the bearing in the arc-shaped groove of the limit plate to prevent the bearing from falling out.

[0017] In some embodiments, the bearing plate may be provided with a first limit post and a second limit post. When the first side of the limit plate abuts against the first limit post, the trough is in the horizontal state. When the second side of the bearing plate abuts against the second limit post, the trough is in the vertical state. The first side and the second side of the bearing plate are perpendicularly arranged.

[0018] Thus, the first limit post and the second limit post can limit the swinging angle of the limit plate. Since the limit plate is fixedly arranged on the rotating shaft and one end of the trough is also fixedly arranged on the rotating shaft, the first limit post and the second limit post can limit the swinging angle of the trough. For example, the swinging angle of the trough is 0 to 90 degrees, that is, the trough can swing from the horizontal state to the vertical state.

[0019] In some embodiments, baffles may be respectively provided on both sides of the trough along its length direction.

[0020] Thus, the edge guards on both sides of the trough can ensure that the end face of the buffer paper pad roll remains flat during the winding process, ensuring the winding quality of the buffer paper pad.

[0021] According to another aspect of the present invention, there is provided a buffer paper pad winding device, comprising a winding mechanism and a floating trough structure. One end of the trough is connected to the discharge port of an external buffer paper pad machine for manufacturing buffer paper pads, and the other end of the trough is arranged at the side of the winding mechanism. The trough can guide the buffer paper pads manufactured by the buffer paper pad machine to the winding mechanism, and the winding mechanism can wind and roll up the buffer paper pads manufactured by the buffer paper pad machine.

[0022] In the buffer paper pad winding device of the present invention, the continuous buffer paper pads manufactured by the external buffer paper pad machine are sent out through the discharge port of the buffer paper pad machine, and the continuous buffer paper pads are conveyed to the winding mechanism through the trough. The winding mechanism can wind and roll up the continuous buffer paper pads. When there is no buffer paper pad on the trough, under the action of the reset component, the trough remains in a horizontal state. When a buffer paper pad roll with a certain diameter is wound on the winding mechanism, the outer circumference of the buffer paper pad roll will push the trough downward. When the trough is subjected to the acting force of the buffer paper pad roll, the trough swings from the horizontal state to a non-horizontal state with the rotating shaft as the swing center. During the winding process of the winding mechanism, the reset component will drive the trough to always be in close contact with the outer circumference of the buffer paper pad roll, ensuring the tightness of the buffer paper pad roll and preventing the buffer paper pad roll from becoming loose during the winding process. When a roll of buffer paper pads is wound up, the adhesive tape mechanism of the buffer paper pad winding device pastes the tape onto the tail of the paper pad of the buffer paper pad roll. As the buffer paper pad winding device is restarted for a certain period of time, the trough always remains in close contact with the tape on the outer circumference of the buffer paper pad roll, thereby ensuring that the tape is firmly pasted and wound around the outer circumference of the buffer paper pad roll to prevent the buffer paper pad roll from coming apart. When it is necessary to remove the wound buffer paper pad roll from the winding mechanism, the driving mechanism drives the limiting plate to swing with the rotating shaft as the swing center, and the limiting plate drives the trough to swing synchronously through the rotating shaft, so that the trough is separated from the outer circumference of the buffer paper pad roll. At this time, the wound buffer paper pad roll can be removed. In the buffer paper pad winding device of the present invention, regardless of whether the buffer paper pad roll wound by the winding mechanism is the minimum diameter or the maximum diameter, the trough is always in close contact with the outer circumference of the buffer paper pad roll, that is, from the minimum diameter to the maximum diameter of the buffer paper pad roll wound by the winding mechanism, the tightness can be ensured. The diameter of the buffer paper pad roll wound by the winding mechanism can be changed between the minimum diameter and the maximum diameter, so that the wound buffer paper pad roll can be adapted to different carton sizes and can be better applied to the buffer packaging of heavy objects. The trough can control the tightness of the buffer paper pad roll, ensuring the consistency of the load-bearing capacity of the buffer paper pad roll during the item packing process, making it more convenient and efficient for the operator to pack items, and can ensure that the tape is firmly pasted and wound around the outer circumference of the buffer paper pad roll to prevent the buffer paper pad roll from coming apart.

[0023] In some embodiments, the winding mechanism may include a turntable, a winding rod, a pusher plate, a first driving component, and a second driving component. The winding rod is provided on the turntable, the first driving component drives the turntable to rotate, the pusher plate is arranged around the periphery of the turntable, and the second driving component can drive the pusher plate to move along the length direction of the winding rod.

[0024] Thus, when the first driving component drives the turntable to rotate, the rotating winding rod on the turntable winds up the buffer paper pads. After the winding is completed, under the action of the second driving component, the pusher plate moves along the length direction of the winding rod, and the pusher plate can push the wound buffer paper pad roll on the winding rod out of the winding rod. Then, under the action of the second driving component, the pusher plate retracts along the length direction of the winding rod to reset, preparing for the next pushing.

[0025] In some embodiments, the winding mechanism may further include a crank - connecting rod mechanism, a guide rod, and a mounting plate. Both the first driving component and the second driving component are provided on the mounting plate. One end of the guide rod is provided on the pusher plate, the guide rod is inserted through the mounting plate, and the guide rod can slide along its length direction. The first driving component is a torque motor. The second driving component is a motor. The input end of the crank - connecting rod mechanism is provided on the rotating shaft of the second driving component, and the output end of the crank - connecting rod mechanism is provided on the pusher plate.

[0026] Thus, the mounting plate can carry the first driving component, the second driving component, the turntable, and the pusher plate. The pusher plate can reciprocate smoothly along the length direction of the winding rod through the guide rod. When the rotating shaft of the motor rotates one circle, through the crank - connecting rod mechanism, the pusher plate can push the buffer paper pad roll on the winding rod out and retract the pusher plate to reset. In addition, the tightness of the buffer paper pad roll during the winding process can also be achieved by adjusting the rotation speed of the torque motor and the discharging speed of the buffer paper pad machine. For example, if the torque motor rotates fast and the discharging speed of the buffer paper pad machine is slow, the winding of the buffer paper pad roll will be relatively tight; if the torque motor rotates slow and the discharging speed of the buffer paper pad machine is fast, the winding of the buffer paper pad roll will be relatively loose. At the same time, under the action of the material groove, the winding mechanism can wind up buffer paper pad rolls with different tightness and different diameters, so as to be better applied to the buffer packaging of heavy objects.

[0027] In some embodiments, it may further include a controller and a diffuse reflection sensor. The diffuse reflection sensor is provided on the side of the winding mechanism, the diffuse reflection sensor is electrically connected to the controller, and the controller is electrically connected to the winding mechanism. The diffuse reflection sensor can detect whether there is a buffer paper pad on the material groove, and the controller can control the winding mechanism to work or stop working.

[0028] Thus, when the starting end of the buffer paper pad on the trough is conveyed to the side position of the winding mechanism, the starting end of the buffer paper pad will be detected by the diffuse reflection sensor. The diffuse reflection sensor sends the detected signal to the controller. After a certain time delay, the controller controls the winding mechanism to start working, and the winding mechanism starts to wind and reel the buffer paper pad. Description of the Drawings

Detailed Embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation 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 specifying the quantity of the indicated technical features.

[0032] Figures 1 to 4 Schematically shows the structure of a floating chute structure for buffering paper pad winding according to an embodiment of the present invention.

[0033] Reference Figures 1 to 4 , a floating chute structure for buffering paper pad winding, includes a chute 1, a rotating shaft 2, a limiting plate 3, a driving mechanism and a reset component. In addition, the floating chute structure may further include a bearing plate 6.

[0034] Reference Figures 1 to 3 , one end of the chute 1 is fixed on the rotating shaft 2. On both sides of the chute 1 along its length direction, there are formed retaining edges 11 respectively. The retaining edges 11 can be formed by bending the two sides of the chute 1 by 90 degrees. The retaining edges 11 on both sides of the chute 1 can ensure that the end face of the buffering paper pad roll remains flat during the winding process, ensuring the winding quality of the buffering paper pad.

[0035] Reference Figure 1 and Figure 3 , the rotating shaft 2 is inserted through the bearing plate 6, and the rotating shaft 2 can rotate on the bearing plate 6. Specifically, the rotating shaft 2 can be installed on the bearing plate 6 through a bearing component 21 so that the rotating shaft 2 can rotate on the bearing plate 6.

[0036] Reference Figures 1 to 3 , the corner position of the limiting plate 3 is fixed on the end of the rotating shaft 2, that is, the end of the rotating shaft 2 is inserted and fixed at the corner position of the limiting plate 3. The bearing plate 6 is located between the chute 1 and the limiting plate 3. The limiting plate 3 and the chute 1 can swing synchronously around the rotating shaft 2 as the swing center. When the chute 1 is subjected to an external force, such as Figure 2 the external force F in Figure 1 the state of Figure 7 the state of

[0037] The reset component can drive the chute 1 to have a tendency to swing from a non-horizontal state to a horizontal state around the rotating shaft 2 as the swing center. Specifically, in this embodiment, referring to Figure 1 and Figure 2 , the reset component is a tension spring 5. One end of the tension spring 5 is fixed on the bearing plate 6, and the other end of the tension spring 5 is fixed on the limiting plate 3. When there is no buffering paper pad on the chute 1, under the pulling force of the tension spring 5, the limiting plate 3 has a tendency to swing around the rotating shaft 2 as the swing center, that is, Figure 2 in Figure 2 the limiting plate 3 in the state of Figure 7In it, when a buffer paper pad roll with a certain diameter is wound on the winding mechanism of the buffer paper pad winding device, the outer circumference of the buffer paper pad roll will push the material trough 1 downward. When the material trough 1 is subjected to the acting force of the buffer paper pad roll, the material trough 1 will swing from the horizontal state ( Figure 2 the state shown) to a non-horizontal state ( Figure 7 the state shown). During the process of winding the buffer paper pad by the buffer paper pad winding device, under the pulling force of the tension spring 5, the material trough 1 will always be in close contact with the outer circumference of the buffer paper pad roll, so as to ensure the tightness of the buffer paper pad roll and prevent the buffer paper pad roll from becoming loose during the winding process. When a roll of buffer paper pad is wound up, the adhesive tape mechanism of the buffer paper pad winding device will paste the tape on the tail of the paper pad of the buffer paper pad roll. As the winding mechanism of the buffer paper pad winding device is started again for a certain period of time, the material trough is always in close contact with the tape on the outer circumference of the buffer paper pad roll, so as to ensure that the tape is firmly pasted and wound around the outer circumference of the buffer paper pad roll.

[0038] Reference Figure 1 and Figure 2 , a first limit post 61 and a second limit post 62 are installed on the bearing plate 6. When the first side of the limit plate 3 ( Figure 2 the upper side of the limit plate 3 in ) abuts against the first limit post 61 ( Figure 2 the state shown), the material trough 1 is in a horizontal state. When the second side of the limit plate 3 ( Figure 2 the left side of the limit plate 3 in ) abuts against the second limit post 62, the material trough 1 is in a vertical state. The first side and the second side of the limit plate 3 are perpendicularly arranged. The first limit post 61 and the second limit post 62 can limit the swing angle of the limit plate 3. Since the limit plate 3 is fixed on the rotating shaft 2 and one end of the material trough 1 is also fixed on the rotating shaft 2, the first limit post 61 and the second limit post 62 can limit the swing angle of the material trough 1. For example, the swing angle of the material trough 1 is 0 to 90 degrees, that is, the material trough 1 can swing from the horizontal state to the vertical state. According to actual needs, by adjusting the installation positions of the first limit post 61 and the second limit post 62 on the bearing plate 6, when the second side of the limit plate 3 ( Figure 2 the left side of the limit plate 3 in ) abuts against the second limit post 62, the material trough 1 can also be in a state close to vertical and non-vertical ( Figure 8 the state shown).

[0039] The driving mechanism can drive the limit plate 3 to swing with the rotating shaft 2 as the swing center. Specifically, refer to Figures 1 to 4, the driving mechanism includes a driving device 41, a connecting rod 42, a bearing 43 and two clamping plates 44. An inclined rod 63 is installed on the mounting plate 6, and a mounting rod 64 is installed on the inclined rod 63. The end of the mounting rod 64 is hinged to the tail of the driving device 41. The driving device 41 can swing on the inclined rod 63 with the mounting rod 64 as the swing center to cooperate with the connecting rod 42 to drive the limiting plate 3 to swing. An arc-shaped groove 31 is formed on the limiting plate 3. One end of the connecting rod 42 is fixed on the driving rod 411 of the driving device 41. The inner ring of the bearing 43 is sleeved on the other end of the connecting rod 42. The bearing 43 is accommodated in the arc-shaped groove 31, that is, the other end of the connecting rod 42 is accommodated in the arc-shaped groove 31 through the bearing 43. The driving device 41 can drive the connecting rod 42 to move along the arc-shaped groove 31. The connecting rod 42 drives the bearing 43 to roll in the arc-shaped groove 31. The connecting rod 42 can move smoothly in the arc-shaped groove 31 through the bearing 43. The bearing 43 can optimize the sliding friction between the connecting rod 42 and the arc-shaped groove 31 into the rolling friction between the bearing 43 and the arc-shaped groove 31, thereby effectively reducing the friction force between the connecting rod 42 and the arc-shaped groove 31 and extending the service life. A limiting groove 441 is formed on the clamping plate 44. The shape of the limiting groove 441 is the same as that of the arc-shaped groove 31. The width of the limiting groove 441 is smaller than the width of the arc-shaped groove 31. The two clamping plates 44 are respectively fixed on both sides of the limiting plate 3. The connecting rod 42 is inserted into a limiting groove 441 and the connecting rod 42 can move in the limiting groove 441. The two clamping plates 44 can limit the bearing 43 in the arc-shaped groove 31 of the limiting plate 3 to prevent the bearing 43 from falling out; when the material chute 1 swings from the horizontal state to the non-horizontal state, the material chute 1 drives the limiting plate 3 to swing synchronously through the rotating shaft 2. The arc-shaped groove 31 on the limiting plate 3 moves along with the bearing 43, that is, the bearing 43 moves in the arc-shaped groove 31 from the first end of the arc-shaped groove 31 ( Figure 1 the position where the bearing 43 is located) to the second end ( Figure 2 the uppermost end of the arc-shaped groove 31 in it). After the buffer paper pad roll is wound up, the driving device 41 drives the bearing 43 to move in the arc-shaped groove 31 in the direction of the first end of the arc-shaped groove 31 through the connecting rod 42. When the bearing 43 moves to the first end of the arc-shaped groove 31, the bearing 43 and the connecting rod 42 drive the limiting plate 3 to swing, and the swinging direction is Figure 2 the clockwise direction in it. The limiting plate 3 drives the material chute 1 to swing synchronously through the rotating shaft 2. The swinging direction of the material chute 1 is still the direction from the horizontal state to the non-horizontal state, that is, Figure 2 the clockwise direction in it. Finally, the material chute 1 is separated from the outer periphery of the buffer paper pad roll ( Figure 8In the state shown, the wound buffer paper pad roll can be removed at this time. After the wound buffer paper pad roll is removed, the driving device 41 drives the connecting rod 42 to reset, and the connecting rod 42 drives the bearing 43 to reset. Under the pulling force of the tension spring 5, the material trough 1 resets to the horizontal state, preparing for the next winding. In addition, the length of the arc-shaped groove 31 can determine the swing angle of the limit plate 3 and the material trough 1. According to needs, the swing angle of the limit plate 3 and the material trough 1 can be adjusted by adjusting the length of the arc-shaped groove 31.

[0040] Reference Figures 1 to 4 , in this embodiment, the driving device 41 is an electric push rod. When the material trough 1 swings from the horizontal state to the non-horizontal state, the material trough 1 drives the limit plate 3 to swing synchronously through the rotating shaft 2. The arc-shaped groove 31 on the limit plate 3 moves along the connecting rod 42, that is, the connecting rod 42 moves in the arc-shaped groove 31 from the first end of the arc-shaped groove 31 ( Figure 1 the position where the bearing 43 is located) to the second end ( Figure 2 the uppermost end of the arc-shaped groove 31 in). After the winding of the buffer paper pad roll is completed, the material trough 1 is in the non-horizontal state at this time ( Figure 7 the state shown). The push rod of the electric push rod extends, and the push rod of the electric push rod drives the connecting rod 42 to move in the arc-shaped groove 31 in the direction of the first end of the arc-shaped groove 31. When the connecting rod 42 moves to the first end of the arc-shaped groove 31, the connecting rod 42 drives the limit plate 3 to swing, and the limit plate 3 drives the material trough 1 to swing synchronously through the rotating shaft 2, finally separating the material trough 1 from the outer periphery of the wound buffer paper pad roll. At this time, the wound buffer paper pad roll can be removed. After the wound buffer paper pad roll is removed, the push rod of the electric push rod retracts. Under the pulling force of the tension spring 5, the connecting rod 42 resets, and the material trough 1 resets to the horizontal state, preparing for the next winding. The electric push rod can quickly separate the material trough 1 from the outer periphery of the buffer paper pad roll, and after removing the wound buffer paper pad roll, the electric push rod can quickly reset the material trough 1 to the horizontal state, ensuring the winding efficiency. In other embodiments, according to needs, the driving device 41 can also adopt a cylinder, a linear motor or other structures that can drive the connecting rod 42 to move along the arc-shaped groove 31.

[0041] Reference Figures 1 to 3 , a photoelectric sensor 7 can also be installed on the bearing plate 6. The photoelectric sensor 7 is connected to the electric push rod (driving device 41) through a controller (microcontroller or CPU). A baffle 32 is installed on the limit plate 3. When the second side of the limit plate 3 ( Figure 2 the left side of the limit plate 3 in) abuts against the second limit post 62, the baffle 32 on the limit plate 3 just blocks the photoelectric sensor 7 to trigger the photoelectric sensor 7. The switching signal generated by the photoelectric sensor 7 is sent to the controller, and the controller controls the electric push rod to stop working. In this way, the stroke of the push rod of the electric push rod does not need to be specially set or selected, as long as when the second side of the limit plate 3 (Figure 2 When the left side of the middle limit plate 3 abuts against the second limit column 62, the electric push rod stops working. When the rolled-up buffer paper pad roll is taken down, the push rod of the electric push rod can be directly retracted.

[0042] The floating trough structure of the present invention is used in conjunction with the buffer paper pad winding device. The continuous buffer paper pad produced by the external buffer paper pad machine can be transported to the buffer paper pad winding device through the trough 1. The buffer paper pad winding device winds up the continuous buffer paper pad. Figures 1 to 4 When there is no buffer paper pad on the material trough 1, the material trough 1 is kept in a horizontal state under the tension of the tension spring 5. When a buffer paper pad roll of a certain diameter is rolled up on the buffer paper pad winding device, the outer periphery of the buffer paper pad roll will push the material trough 1 downward. When the material trough 1 is subjected to the force of the buffer paper pad roll, the material trough 1 swings from a horizontal state to a non-horizontal state with the rotating shaft 2 as the swing center. Since the tension spring 5 can drive the material trough 1 to maintain a tendency to swing from a non-horizontal state to a horizontal state with the rotating shaft 2 as the swing center, the tension spring 5 will drive the material trough 1 to always be in close contact with the outer periphery of the buffer paper pad roll during the winding process of the buffer paper pad winding device ( Figure 7 The adhesive tape of the material trough 1 is fixed to the outer periphery of the buffer paper pad roll and the ... The floating material trough structure of the invention, no matter the buffer paper pad roll rolled up by the buffer paper pad rolling device has the minimum diameter or the maximum diameter, the material trough 1 is in close contact with the outer circumference of the buffer paper pad roll, that is, the buffer paper pad roll rolled up by the buffer paper pad rolling device can be guaranteed to have a tightness from the minimum diameter to the maximum diameter, and the diameter of the buffer paper pad roll rolled up by the buffer paper pad rolling device can be changed between the minimum diameter and the maximum diameter, so that the rolled buffer paper pad roll can be adapted to different carton sizes and can be better used in the buffering packaging of heavy objects. The material trough 1 can control the tightness of the buffer paper pad roll, thereby ensuring the consistency of the load-bearing capacity of the buffer paper pad roll during the packaging process of items, making it more convenient and efficient for operators to pack items, and can ensure that the tape is firmly adhered and wrapped around the outer circumference of the buffer paper pad roll to prevent the buffer paper pad roll from spreading.

[0043] Figure 5 and Figure 6Schematically shows the structure of a buffer paper pad winding device according to an embodiment of the present invention.

[0044] Reference Figure 5 and Figure 6 , a buffer paper pad winding device, comprising a winding mechanism 10, a floating chute structure, a controller and a diffuse reflection sensor 100.

[0045] Reference Figure 5 and Figure 6 , the buffer paper pad winding device of the present invention is used in cooperation with a buffer paper pad machine 200 for making buffer paper pads. A tape pasting mechanism is installed below the discharge port 201 of the buffer paper pad machine 200. The tape pasting mechanism can adopt existing equipment for automatically pasting tapes, and the tape pasting mechanism is not the object of protection of the present invention. One end of the chute 1 is installed at the discharge port 201 of the buffer paper pad machine 200, and the other end of the chute 1 is installed on the side of the winding mechanism 10. One end of the rotating shaft 2 is installed on the bearing plate 6 through a bearing member 21 ( Figure 3 as shown), and the other end of the rotating shaft 2 is also installed in a fixed box 22 through a bearing member ( Figure 3 as shown). The fixed box 22 is installed below the discharge port 201 of the buffer paper pad machine 200. The chute 1 can guide the buffer paper pads made by the buffer paper pad machine 200 to the winding mechanism 10, and the winding mechanism 10 can wind and wind the buffer paper pads made by the buffer paper pad machine 200.

[0046] Reference Figure 5 and Figure 6The winding mechanism 10 includes a turntable 20, a winding rod 30, a push plate 40, a first driving component 50, a second driving component 60, a crank connecting rod mechanism 70, a guide rod 80 and a mounting plate 90. The end of the winding rod 30 is fixed on the turntable 20. There are two winding rods 30, which are respectively located at the two ends of the turntable 20 in the diameter direction. The first driving component 50 is installed on the mounting plate 90. The first driving component 50 drives the turntable 20 to rotate through the transmission mechanism of "two synchronous wheels 501 + synchronous belt (not shown)". The first driving component 50 can The torque motor is adopted, the push plate 40 is annular, the inner diameter of the push plate 40 is slightly larger than the outer diameter of the turntable 20, the push plate 40 is annularly arranged on the periphery of the turntable 20, the guide rod 80 is inserted into the mounting plate 90 through a shaft sleeve, one end of the guide rod 80 is fixed on the push plate 40, and the guide rod 80 can slide on the mounting plate 90 along its length direction, the second driving component 60 is a motor, the second driving component 60 is mounted on the mounting plate 90, the input end of the crank connecting rod mechanism 70 is mounted on the rotating shaft of the second driving component 60, and the output end of the crank connecting rod mechanism 70 is fixed on On the push plate 40, the second driving component 60 can drive the push plate 40 to move along the length direction of the winding rod 30 through the crank connecting rod mechanism 70; the mounting plate 90 can carry the first driving component 50, the second driving component 60, the turntable 20, and the push plate 40. The push plate 40 can smoothly reciprocate along the length direction of the winding rod 30 through the guide rod 80. The rotating shaft of the second driving component 60 (i.e., the motor) rotates one circle, and the crank connecting rod mechanism 70 can drive the push plate 40 to push out the buffer paper pad on the winding rod 30 and retract and reset the push plate 40. In addition, The tightness of the buffer paper pad roll during the winding process can be achieved by adjusting the rotation speed of the torque motor (first drive component 50) and the discharge speed of the buffer paper pad machine 400. For example, if the torque motor rotates faster and the discharge speed of the buffer paper pad machine 200 is slower, the buffer paper pad roll will be wound tighter; if the torque motor rotates slower and the discharge speed of the buffer paper pad machine 200 is faster, the buffer paper pad roll will be wound looser. At the same time, under the action of the material trough 1, the winding mechanism 10 can wind up buffer paper pad rolls of different tightness and diameters, so that it can be better used in the cushioning packaging of heavy objects.

[0047] refer to Figure 5 and Figure 6 The number of guide rods 80 is three, and the installation positions of the three guide rods 80 on the push plate 40 are arranged in a triangle. Under the driving action of the second driving component 60, the push plate 40 can smoothly reciprocate along the two winding rods 30. In other embodiments, the number of guide rods 80 can be adjusted as needed.

[0048] refer to Figure 5 and Figure 6, the diffuse reflection sensor 100 is installed on the mounting plate 90. The mounting plate 90 is formed with a first through hole 901 for the light emitted by the diffuse reflection sensor 100 to pass through. The pusher plate 40 is formed with a second through hole 401 for the light emitted by the diffuse reflection sensor 100 to pass through. The diffuse reflection sensor 100 is located at the side of the turntable 20. The diffuse reflection sensor 100 emits light and receives the light reflected by the object, and judges the presence of the material according to the change in the received light intensity. The diffuse reflection sensor 100 can detect whether there is a buffer paper pad on the material tank 1. The diffuse reflection sensor 100 is connected to a controller (not shown) through a wire harness. The controller can be a microcontroller or a single-chip microcomputer. The controller is connected to the first driving component 50 of the winding mechanism 10 through a wire harness. The controller can control the first driving component 50 to start working or stop working. When the starting end of the buffer paper pad on the material tank 1 is conveyed to the side position of the turntable 20, the starting end of the buffer paper pad will be detected by the diffuse reflection sensor 100 through the first through hole 901 and the second through hole 401. The diffuse reflection sensor 100 sends the detected signal to the controller. After a certain time delay, the controller controls the first driving component 50 to start working, and the winding rod 30 on the turntable 20 starts to wind and wind up the buffer paper pad.

[0049] Figure 7 and Figure 8 Schematically shows the use state of the buffer paper pad winding device shown in 5.

[0050] Reference Figures 1 to 8 , the continuous buffer paper pads made by the buffer paper pad machine 200 are conveyed to the winding mechanism 10 through the discharge port 201 and the material tank 1. The tape pasting mechanism 300 is installed below the discharge port 201 of the buffer paper pad machine 200. There is a window below the discharge port 201. A tape roll 301 is installed below the tape pasting mechanism 300. The tape pasting mechanism 300 can paste the tape on the tape roll 301 onto the buffer paper pad in the discharge port 201 through the window. A cutter component is installed at the discharge port 201 of the buffer paper pad machine 200; when there is no buffer paper pad on the material tank 1, under the pulling force of the tension spring 5, the material tank 1 remains in a horizontal state ( Figure 2 the state shown in), when the starting end of the buffer paper pad is detected by the diffuse reflection sensor 100, after a certain time delay, the controller controls the first driving component 50 to start working, and the winding rod 30 on the turntable 20 rotates clockwise to start winding and winding up the buffer paper pad. When a buffer paper pad roll 400 with a certain diameter is wound on the two winding rods 30, the outer periphery of the buffer paper pad roll 400 will push down the material tank 1. When the material tank 1 is subjected to the force of the buffer paper pad roll 400, the material tank 1 swings into a non-horizontal state ( Figure 7In the state shown, during the winding process, the tension spring 5 will drive the material trough 1 to always be in close contact with the outer periphery of the buffer paper pad roll 400, ensuring the tightness of the buffer paper pad roll 400 and preventing the buffer paper pad roll 400 from becoming loose during the winding process. At the same time, the edge guards 11 on both sides of the material trough 1 can ensure that the end faces of the buffer paper pad roll 400 remain flat during the winding process. When the buffer paper pad machine 200 sends out a set length of buffer paper pads from the discharge port 201, the cutting tool component at the discharge port 201 of the buffer paper pad machine 200 cuts the buffer paper pads. When the two winding rods 30 are about to complete the winding of a set length of buffer paper pads, the tape pasting mechanism 300 pastes the tape on the tail of the paper pads of the wound buffer paper pad roll 400. As the first driving component 50 starts again for a certain period of time, the material trough 1 always remains in close contact with the tape on the outer periphery of the buffer paper pad roll 400. Then, the cutting tool component at the discharge port 201 of the buffer paper pad machine 200 automatically or manually pierces or cuts the tape. The two winding rods 30 wind and tighten the remaining unpasted tape on the buffer paper pad roll 400. The tape is firmly pasted and wound around the outer periphery of the buffer paper pad roll 400. When it is necessary to remove the wound buffer paper pad roll 400 from the winding rod 30, the driving device 41 drives the limiting plate 3 to swing with the rotating shaft 2 as the swing center. The limiting plate 3 drives the material trough 1 to swing synchronously through the rotating shaft 2, so that the material trough 1 is separated from the outer periphery of the buffer paper pad roll. Figure 8 In the state shown), then under the driving action of the second driving component 60, the pusher plate 40 moves along the length direction of the winding rod 30, and the pusher plate 40 can push the wound buffer paper pad roll 400 on the winding rod 30 out of the winding rod 30. Then the pusher plate 40 retracts along the length direction of the winding rod 30 to reset and prepare for the next pushing; for the buffer paper pad winding device of the present invention, regardless of whether the buffer paper pad roll wound by the winding mechanism 10 has the minimum diameter or the maximum diameter, the material trough 1 is in close contact with the outer periphery of the buffer paper pad roll, that is, the buffer paper pad roll wound by the winding mechanism 10 can ensure the tightness from the minimum diameter to the maximum diameter. The diameter of the buffer paper pad roll wound by the winding mechanism 10 can be changed between the minimum diameter and the maximum diameter, so that the wound buffer paper pad roll can adapt to different carton sizes and can be better applied to the cushioning packaging of heavy objects. The material trough 1 can control the tightness of the buffer paper pad roll, ensuring the consistency of the load-bearing capacity of the buffer paper pad roll during the item packing process, making it more convenient and efficient for the operator to pack items, and can ensure that the tape is firmly pasted and wound around the outer periphery of the buffer paper pad roll to prevent the buffer paper pad roll from coming apart.
