Description

Technical Field

[0001] This utility model relates to a floating feeder structure and a buffer paper rewinding device for winding buffer paper pads. Background Technology

[0002] When packaging heavy items, if the cushioning paper pads used for packaging are insufficient, they are easily flattened. If the cushioning paper pads are excessive, there are certain requirements for the stacking method and quantity of the cushioning paper pads to ensure that the heavy items are well supported and have limited movement in all directions inside the box.

[0003] Existing cushioning paper pad equipment produces cushioning paper pads in segments. These cushioning paper pads do not provide good cushioning during the packing of heavy objects. Furthermore, packers need to manually place the cushioning paper pads into the carton in a certain arrangement to cushion the heavy objects. This method is labor-intensive, and the cushioning effect of manually stacked cushioning paper pads is inconsistent.

[0004] Currently, cushioning paper rewinders can rewind continuous cushioning paper into a roll. However, the diameter of the rewound cushioning paper roll is basically fixed or only has a few specific diameters, resulting in poor applicability and inability to adapt to different carton sizes. Moreover, the tightness of the rewound cushioning paper roll is also poor, generally looser than expected. Usually, operators need to adjust the tightness before wrapping tape to fix it. The tape wrapping method is usually: the tape applicator applies tape to the end of the cushioning paper roll. As the cushioning paper rewinder restarts for a certain period of time, the tape can be wrapped around the outer perimeter of the cushioning paper roll. However, it is difficult to guarantee the firmness of the tape on the outer perimeter of the cushioning paper roll in this way. If the cushioning paper roll is wound tightly, the tape will be firmly attached to the outer perimeter of the cushioning paper roll. If the cushioning paper roll is wound loosely, the tape will not be firmly attached to the outer perimeter of the cushioning paper roll, resulting in a loose cushioning paper roll that cannot meet the winding requirements.

[0005] Therefore, overcoming the aforementioned technical deficiencies is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a floating feeder structure and a buffer paper pad winding device for winding buffer paper pads, so as to solve at least one of the above-mentioned technical problems.

[0007] According to one aspect of the present invention, a floating feeder structure for winding cushioning paper pads is provided, comprising:

[0008] Trough;

[0009] A rotatable shaft is used, with one end of the material trough fixed to the shaft and the other end of the material trough having flanges arranged at an obtuse angle to the material trough.

[0010] When the trough is subjected to external force, the trough can swing from a horizontal state to a non-horizontal state with the pivot as the swing center;

[0011] A limiting plate is fixed on the rotating shaft;

[0012] The drive mechanism can drive the limit plate to swing around the pivot axis; and

[0013] The reset component can drive the feed trough to maintain a tendency to swing from a non-horizontal state to a horizontal state with the pivot axis as the swing center.

[0014] The floating feed trough structure of this utility model is used in conjunction with a buffer paper pad winding device. Continuous buffer paper pads produced by an external buffer paper pad machine can be conveyed to the buffer paper pad winding device through the feed trough. The buffer paper pad winding device winds up the continuous buffer paper pads. When there are no buffer paper pads on the feed trough, the feed trough remains horizontal under the action of the reset component. When the buffer paper pad winding device winds up a buffer paper pad roll of a certain diameter, the outer circumference of the buffer paper pad roll will push the feed trough downwards. When the feed trough is subjected to the force of the buffer paper pad roll, the feed trough swings from a horizontal state to a non-horizontal state around the pivot axis. Due to the reset component driving the feed trough to remain horizontal... The device tends to oscillate from a non-horizontal to a horizontal state around its pivot point. Therefore, during the winding process, the reset component of the cushioning paper roll ensures the feed trough remains tightly pressed against the outer periphery of the roll, maintaining the roll's tightness and preventing it from becoming loose during winding. The flange on the feed trough prevents its end from getting stuck on the outer periphery of the roll and guides the roll smoothly during winding. After one roll of cushioning paper is wound, the tape application mechanism of the device applies tape to the tail of the paper roll. As the device restarts, a certain amount of time is required for the tape to adhere. During this process, the feed trough remains firmly attached to the tape on the outer periphery of the cushioning paper roll, ensuring the tape is securely adhered and wrapped around the roll, preventing it from unraveling. When the wound-up cushioning paper roll needs to be removed from the cushioning paper roll winding device, the drive mechanism drives the limiting plate to swing around the pivot shaft. The limiting plate, through the pivot shaft, causes the feed trough to swing synchronously, separating it from the outer periphery of the cushioning paper roll. At this point, the wound-up cushioning paper roll can be removed. This floating feed trough structure ensures that the feed trough remains firmly attached to the outer periphery of the cushioning paper roll regardless of whether the cushioning paper roll being wound by the winding device is of minimum or maximum diameter. The cushioning paper roll rewinding device ensures that the tightness of the rolled cushioning paper roll can be maintained from the minimum to the maximum diameter. The diameter of the rolled cushioning paper roll can be varied between the minimum and maximum diameters, allowing the rolled cushioning paper roll to adapt to different carton sizes and better suited for cushioning packaging of heavy items. The material trough can control the tightness of the cushioning paper roll, ensuring the consistency of the load-bearing capacity of the cushioning paper roll during the packing process, making the packing process more convenient and efficient for operators. It also ensures that the tape is firmly adhered to the outer periphery of the cushioning paper roll, preventing the cushioning paper roll from unraveling.

[0015] In some embodiments, a support plate may also be included, with the rotating shaft inserted through the support plate and rotatable on the support plate.

[0016] The reset component is a tension spring, with one end of the tension spring located on the bearing plate and the other end located on the limiting plate.

[0017] Therefore, the bearing plate can support the rotating shaft and the material trough. When there is no cushioning paper pad on the material trough, under the tension of the tension spring, the limiting plate tends to swing around the rotating shaft as the swing center. The limiting plate drives the material trough to swing from a non-horizontal state to a horizontal state around the rotating shaft as the swing center, keeping the material trough in a horizontal state. When the cushioning paper pad winding device winds up a cushioning paper pad roll of a certain diameter, the outer circumference of the cushioning paper pad roll will push the material trough downward. When the material trough is subjected to the force of the cushioning paper pad roll, the material trough will swing from a horizontal state to a non-horizontal state around the rotating shaft as the swing center. In a flat state, during the winding process, the feed trough of the cushioning paper roll remains tightly pressed against the outer periphery of the cushioning paper roll under the tension of the spring, ensuring the tightness of the cushioning paper roll and preventing it from becoming loose during winding. After one roll of cushioning paper is wound up, the tape-adhesive mechanism of the cushioning paper roll winding device adheres the tape to the tail of the paper roll. As the cushioning paper roll winding device restarts for a certain period of time, the feed trough remains tightly pressed against the tape on the outer periphery of the cushioning paper roll, thus ensuring that the tape is firmly adhered and wrapped around the outer periphery of the cushioning paper roll.

[0018] In some implementations, the limiting plate may be provided with an arc-shaped groove.

[0019] The driving mechanism may include a driving device and a connecting rod. One end of the connecting rod is disposed on the driving rod of the driving device, and the other end of the connecting rod is accommodated in an arc-shaped groove. The driving device can drive the connecting rod to move along the arc-shaped groove.

[0020] Therefore, when the feed trough swings from a horizontal state to a non-horizontal state, the feed trough drives the limiting plate to swing synchronously through the rotating shaft. The arc-shaped groove on the limiting plate moves along the connecting rod, that is, the connecting rod moves from the first end to the second end of the arc-shaped groove. The length of the arc-shaped groove can determine the swing angle of the limiting plate and the feed trough. After the buffer paper roll is wound up, the drive device drives the connecting rod to move 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 feed trough to swing synchronously through the rotating shaft. The swing direction of the feed trough is still from the horizontal state to the non-horizontal state, which eventually separates the feed trough from the outer periphery of the buffer paper roll. At this time, the wound buffer paper roll can be removed. After the wound buffer paper roll is removed, the drive device drives the connecting rod to reset. The reset component drives the feed trough to reset to a horizontal state, preparing for the next winding.

[0021] In some implementations, the drive device may be an electric actuator.

[0022] Therefore, when the feed trough swings from a horizontal to a non-horizontal state, the feed trough drives the limiting plate to swing synchronously via the rotating shaft. The arc-shaped groove on the limiting plate moves along the connecting rod, that is, the connecting rod moves from the first end to the second end of the arc-shaped groove. After the buffer paper roll is wound up, the push rod of the electric push rod extends, and the push rod of the electric push rod drives the connecting rod to move 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, and the limiting plate drives the limiting plate to swing via the rotating shaft. The feed trough swings synchronously, eventually separating from the outer periphery of the buffer paper roll. At this point, the wound buffer paper roll can be removed. After the wound buffer paper roll is removed, the push rod of the electric push rod retracts, the connecting rod resets, and the reset component drives the feed trough to return to a horizontal state, preparing for the next winding. The electric push rod can quickly separate the feed trough from the outer periphery of the buffer paper roll, and after the wound buffer paper roll is removed, the electric push rod can quickly reset the feed trough to a horizontal state, ensuring winding efficiency.

[0023] In some embodiments, the drive mechanism may further include a bearing and two clamping plates. The bearing is located on the other end of the connecting rod and is housed in an arc-shaped groove. The clamping plates are provided with limiting grooves. The two clamping plates are respectively located on both sides of the limiting plate. The connecting rod is inserted into a limiting groove and can move along the limiting groove. The width of the limiting groove is smaller than the width of the arc-shaped groove.

[0024] Therefore, the connecting rod can move smoothly in the arc groove through the bearing, optimizing the sliding friction between the connecting rod and the arc groove into the rolling friction between the bearing and the arc groove, thereby effectively reducing the friction between the connecting rod and the arc groove and extending the service life. The two clamps can limit the bearing in the arc groove of the limiting plate to prevent the bearing from falling out.

[0025] In some embodiments, the support plate may be provided with a first limiting post and a second limiting post.

[0026] When the first side of the limiting plate abuts against the first limiting post, the material trough is in a horizontal state.

[0027] When the second side of the bearing plate abuts against the second limiting post, the material trough is in a vertical position.

[0028] The first and second sides of the support plate are arranged perpendicularly.

[0029] Therefore, the first and second limiting posts can limit the swing angle of the limiting plate. Since the limiting plate is fixed on the rotating shaft and one end of the material trough is also fixed on the rotating shaft, the first and second limiting posts can limit the swing angle of the material trough. For example, the swing angle of the material trough is 0 to 90 degrees, that is, the material trough can swing from a horizontal state to a vertical state.

[0030] In some embodiments, the feed trough may be provided with side flanges on both sides along its length.

[0031] Therefore, the side guards on both sides of the feed trough can ensure that the end face of the buffer paper roll remains flat during the winding process, thus ensuring the winding quality of the buffer paper.

[0032] According to another aspect of the present invention, a cushioning paper pad winding device is provided, including a winding mechanism and a floating material trough structure. One end of the material trough is connected to the discharge port of an external cushioning paper pad machine for making cushioning paper pads, and the other end of the material trough is located on the side of the winding mechanism. The material trough can guide the cushioning paper pads made by the cushioning paper pad machine to the winding mechanism, and the winding mechanism can wind and rewind the cushioning paper pads made by the cushioning paper pad machine.

[0033] This utility model discloses a buffer paper pad winding device. A continuous buffer paper pad produced by an external buffer paper pad machine is fed out through the machine's outlet. The continuous buffer paper pad is then conveyed to a winding mechanism via a feed trough. The winding mechanism winds the continuous buffer paper pad. When there is no buffer paper pad on the feed trough, the feed trough remains horizontal under the action of a reset component. When a buffer paper pad roll of a certain diameter is wound onto the winding mechanism, the outer circumference of the roll pushes downwards into the feed trough. Under the force of the buffer paper pad roll, the feed trough swings from a horizontal state to a non-horizontal state around its pivot axis. During the winding process, the reset component drives the feed trough to remain tightly pressed against the outer periphery of the cushioning paper roll, ensuring the tightness of the cushioning paper roll and preventing it from becoming loose during winding. The flange on the feed trough prevents the end of the feed trough from getting stuck on the outer periphery of the cushioning paper roll and guides the cushioning paper roll to wind smoothly. After one roll of cushioning paper is wound, the tape application mechanism of the cushioning paper roll winding device applies tape to the tail of the paper roll. As the cushioning paper roll winding device restarts for a certain period, the feed trough remains tightly pressed against the outer periphery of the cushioning paper roll. The tape is firmly adhered to ensure it is securely wrapped around the outer circumference of the cushioning paper roll, preventing it from unraveling. When the wound cushioning paper roll needs to be removed from the winding mechanism, the drive mechanism drives the limiting plate to swing around the pivot shaft. The limiting plate, through the pivot shaft, drives the material trough to swing synchronously, separating the material trough from the outer circumference of the cushioning paper roll. At this point, the wound cushioning paper roll can be removed. In this invention's cushioning paper roll winding device, regardless of whether the wound cushioning paper roll has the smallest or largest diameter, the material trough remains firmly attached to the outer circumference of the cushioning paper roll, meaning the winding mechanism... The cushioning paper roll can maintain a consistent tightness from its minimum to maximum diameter. The diameter of the cushioning paper roll wound by the rewinding mechanism can vary between the minimum and maximum diameters, allowing the wound cushioning paper roll to adapt to different carton sizes and be better suited for cushioning packaging heavy items. The feed trough can control the tightness of the cushioning paper roll, ensuring the consistency of the load-bearing capacity of the cushioning paper roll during the packing process. This makes the packing process more convenient and efficient for operators, and also ensures that the tape is firmly adhered to the outer periphery of the cushioning paper roll, preventing the cushioning paper roll from unraveling.

[0034] 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 disposed on the turntable, the first driving component drives the turntable to rotate, the pusher plate is disposed 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.

[0035] Therefore, when the first driving component drives the turntable to rotate, the rotating winding rod on the turntable will wind up the buffer paper pad. 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. The pusher plate can push the wound buffer paper pad roll off 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 and prepare for the next push.

[0036] In some embodiments, the winding mechanism may further include a crank-connecting rod mechanism, a guide rod, and a mounting plate, with both the first and second drive components mounted on the mounting plate.

[0037] One end of the guide rod is mounted on the pusher plate, and the guide rod is inserted into the mounting plate. The guide rod can slide along its length.

[0038] The first driving component is a torque motor.

[0039] The second driving component is a motor. The input end of the crank-connecting rod mechanism is located on the rotating shaft of the second driving component, and the output end of the crank-connecting rod mechanism is located on the pusher plate.

[0040] Therefore, the mounting plate can support the first drive component, the second drive component, the turntable, and the pusher plate. The pusher plate can move smoothly back and forth along the length of the winding rod via the guide rod. When the motor shaft rotates once, the pusher plate can be driven by the crank-connecting rod mechanism to push out the cushioning paper roll on the winding rod and retract the pusher plate to its original position. In addition, the tightness of the cushioning paper roll during the winding process can also be adjusted by adjusting the speed of the torque motor and the output speed of the cushioning paper roll machine. For example, if the torque motor rotates fast and the output speed of the cushioning paper roll machine is slow, the cushioning paper roll will be wound tighter. If the torque motor rotates slowly and the output speed of the cushioning paper roll machine is fast, the cushioning paper roll will be wound looser. At the same time, under the action of the material trough, the winding mechanism can wind out cushioning paper rolls with different tightness and different diameters, so as to better apply them to the cushioning packaging of heavy objects.

[0041] In some embodiments, the system may further include a controller and a diffuse reflection sensor. The diffuse reflection sensor is located on the side of the winding mechanism and is electrically connected to the controller, which is in turn electrically connected to the winding mechanism.

[0042] The diffuse reflection sensor can detect whether there is a buffer paper pad on the feed trough, and the controller can control the winding mechanism to work or stop working.

[0043] Therefore, when the starting end of the buffer paper pad on the feed 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 will send the detected signal to the controller. After a certain delay, the controller will control the winding mechanism to start working, and the winding mechanism will start to wind and rewind the buffer paper pad. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0054] Figures 1 to 4 The diagram schematically illustrates the structure of a floating feeder structure for winding a cushioning paper pad according to one embodiment of the present invention.

[0055] refer to Figures 1 to 4 A floating feeder structure for winding cushioning paper pads includes a feeder 1, a rotating shaft 2, a limiting plate 3, a drive mechanism, and a reset component. Furthermore, the floating feeder structure may also include a support plate 6.

[0056] refer to Figures 1 to 3 One end of the material trough 1 is fixed on the rotating shaft 2. The material trough 1 has baffles 11 formed on both sides along its length. The baffles 11 can be formed by bending the two sides of the material trough 1 at 90 degrees. The baffles 11 on both sides of the material trough 1 can ensure that the end face of the buffer paper roll remains flat during the winding process, thus ensuring the winding quality of the buffer paper.

[0057] refer to Figure 1 The lengths of the two guard edges 11 can be designed to be different. The length of the guard edge 11 farther away from the support plate 6 is greater than the length of the guard edge 11 closer to the support plate 6. The longer guard edge 11 can further prevent the outermost buffer paper pad of the buffer paper pad roll from bulging outward during the winding process, ensuring that the end face of the buffer paper pad roll remains flat.

[0058] refer to Figures 1 to 3 The other end of trough 1 ( Figure 2 A flange 12 is formed on the right end of the material trough 1. The flange 12 is arranged at an obtuse angle to the material trough 1, and there is an arc transition between the flange 12 and the material trough 1. During the winding process of the buffer paper pad roll, due to the presence of the reset component, the flange 12 and the arc transition between the flange 12 and the material trough 1 can prevent the end of the material trough 1 from getting stuck on the outer periphery of the buffer paper pad roll. The flange 12, which is arranged at an obtuse angle to the material trough 1, can guide the buffer paper pad roll to wind smoothly.

[0059] refer to Figure 1 and Figure 3 The rotating shaft 2 is inserted in the support plate 6 and can rotate on the support plate 6. Specifically, the rotating shaft 2 can be mounted on the support plate 6 through a bearing component 21 so that the rotating shaft 2 can rotate on the support plate 6.

[0060] refer to Figures 1 to 3 The corner of the limiting plate 3 is fixed to the end of the rotating shaft 2, that is, the end of the rotating shaft 2 is inserted and fixed at the corner of the limiting plate 3. The bearing plate 6 is located between the material trough 1 and the limiting plate 3. The limiting plate 3 and the material trough 1 can swing synchronously around the rotating shaft 2 as the swing center through the rotating shaft 2. When the material trough 1 is subjected to external force, such as Figure 2 The external force F in the middle allows the material trough 1 and the limiting plate 3 to swing about the rotating shaft 2 from a horizontal state ( Figure 1 The state) swings into a non-horizontal state ( Figure 7 (in the state of the load), the bearing plate 6 can support the rotating shaft 2 and the material trough 1.

[0061] The reset component can drive the feed trough 1 to maintain a tendency to swing from a non-horizontal state to a horizontal state with the pivot 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 to the bearing plate 6, and the other end is fixed to the limiting plate 3. When there is no buffer paper pad on the material trough 1, under the tension of the tension spring 5, the limiting plate 3 maintains a tendency to swing around the pivot 2 as the swing center. Figure 2 The middle limiting plate 3 maintains a counterclockwise swinging tendency around the pivot 2. The limiting plate 3 drives the material trough 1 to maintain a swinging tendency from a non-horizontal state to a horizontal state around the pivot 2, thus keeping the material trough 1 in a horizontal state. Figure 2 (as shown in the image) Figure 7 In the process, when a buffer paper roll of a certain diameter is wound on the winding mechanism of the buffer paper roll winding device, the outer circumference of the buffer paper roll will push the material trough 1 downward. When the material trough 1 is subjected to the force of the buffer paper roll, the material trough 1 will swing about the rotating shaft 2 as the center of the swing from a horizontal state ( Figure 2 The state shown) swings into a non-horizontal state ( Figure 7 As shown in the diagram, during the winding process of the cushioning paper pad, under the tension of the tension spring 5, the feed trough 1 will always be tightly attached to the outer periphery of the cushioning paper pad roll, thereby ensuring the tightness of the cushioning paper pad roll and preventing the cushioning paper pad roll from becoming loose during the winding process. After a roll of cushioning paper pad is wound up, the tape pasting mechanism of the cushioning paper pad winding device will paste the tape onto the tail of the paper pad of the cushioning paper pad roll. As the winding mechanism of the cushioning paper pad winding device restarts for a certain period of time, the feed trough will always be tightly attached to the tape on the outer periphery of the cushioning paper pad roll, thereby ensuring that the tape is firmly pasted and wrapped around the outer periphery of the cushioning paper pad roll.

[0062] refer to Figure 1 and Figure 2 The bearing plate 6 is equipped with a first limiting post 61 and a second limiting post 62. When the first side of the limiting plate 3 ( Figure 2 When the upper side of the middle limiting plate 3 abuts against the first limiting post 61 ( Figure 2 As shown in the diagram, the material trough 1 is in a horizontal state, and when the second side of the limiting plate 3 ( Figure 2When the left side of the middle limiting plate 3 abuts against the second limiting post 62, the material trough 1 is in a vertical state. The first and second sides of the limiting plate 3 are arranged perpendicularly. The first limiting post 61 and the second limiting post 62 can limit the swing angle of the limiting plate 3. Since the limiting 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 limiting post 61 and the second limiting 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 a horizontal state to a vertical state. According to actual needs, by adjusting the installation position of the first limiting post 61 and the second limiting post 62 on the bearing plate 6, when the second side of the limiting plate 3 ( Figure 2 When the left side of the middle limiting plate 3 abuts against the second limiting post 62, the material trough 1 can also be in a near-vertical but not vertical state. Figure 8 (The state shown).

[0063] The drive mechanism can drive the limit plate 3 to swing around the pivot 2 as the swing center. Specifically, refer to... Figures 1 to 4 The drive mechanism includes a drive unit 41, a connecting rod 42, a bearing 43, and two clamping plates 44. A diagonal rod 63 is mounted on the mounting plate 6, and a mounting rod 64 is mounted on the diagonal rod 63. The end of the mounting rod 64 is hinged to the tail of the drive unit 41. The drive unit 41 can swing around the mounting rod 64 as its swing center on the diagonal rod 63 to cooperate with the connecting rod 42 in driving the limiting plate 3 to swing. The limiting plate 3 has an arc-shaped groove 31 formed on it. One end of the connecting rod 42 is fixed to the drive rod 411 of the drive unit 41. The inner ring of the bearing 43 is fitted onto the other end of the connecting rod 42. The bearing 43 is housed in the arc-shaped groove 31, meaning the other end of the connecting rod 42 is housed in the arc-shaped groove 31 via the bearing 43. The drive unit 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 via the bearing 43. 43 can optimize the sliding friction between the connecting rod 42 and the arc groove 31 into the rolling friction between the bearing 43 and the arc groove 31, thereby effectively reducing the friction between the connecting rod 42 and the arc groove 31 and extending the service life. The clamping plate 44 is formed with a limiting groove 441. The shape of the limiting groove 441 is consistent with the shape of the arc groove 31. The width of the limiting groove 441 is smaller than the width of the arc 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 can move in the limiting groove 441. The two clamping plates 44 can limit the bearing 43 in the arc groove 31 of the limiting plate 3 to prevent the bearing 43 from falling out. When the material trough 1 swings from a horizontal state to a non-horizontal state, the material trough 1 drives the limiting plate 3 to swing synchronously through the rotating shaft 2. The arc groove 31 on the limiting plate 3 moves along the bearing 43, that is, the bearing 43 moves from the first end of the arc groove 31 in the arc groove 31. Figure 1 The position of the middle bearing 43) towards the second end ( Figure 2 The drive device 41 moves towards the uppermost end of the arc-shaped groove 31. After the buffer paper roll is wound up, the drive device 41 drives the bearing 43 to move towards the first end of the arc-shaped groove 31 via 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 cause the limiting plate 3 to swing in the direction of swing. Figure 2 In the clockwise direction, the limiting plate 3 drives the material trough 1 to swing synchronously via the rotating shaft 2. The swing direction of the material trough 1 is still from the horizontal state to the non-horizontal state. Figure 2 The clockwise direction in the middle eventually separates the feed trough 1 from the outer periphery of the buffer paper roll. Figure 8 (As shown in the diagram), the wound-up cushioning paper roll can then be removed. After the wound-up cushioning paper roll is removed, the drive device 41 drives the connecting rod 42 to reset, and the connecting rod 42 drives the bearing 43 to reset. Under the tension of the tension spring 5, the material trough 1 resets to a horizontal state, preparing for the next winding. In addition, the length of the arc-shaped groove 31 can determine the swing angle of the limiting plate 3 and the material trough 1. As needed, the swing angle of the limiting plate 3 and the material trough 1 can be adjusted by adjusting the length of the arc-shaped groove 31.

[0064] refer to Figures 1 to 4 In this embodiment, the driving device 41 is an electric push rod. When the material trough 1 swings from a horizontal state to a non-horizontal state, the material trough 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 the connecting rod 42, that is, the connecting rod 42 moves from the first end of the arc-shaped groove 31 in the arc-shaped groove 31. Figure 1 The position of the middle bearing 43) towards the second end ( Figure 2 The material trough 1 moves in the direction of the uppermost end of the arc-shaped groove 31. After the buffer paper roll is wound up, the material trough 1 is in a non-horizontal state. Figure 7 (As shown in the diagram), 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 towards the first end of the arc groove 31. When the connecting rod 42 moves to the first end of the arc groove 31, the connecting rod 42 drives the limiting plate 3 to swing. The limiting plate 3 drives the material groove 1 to swing synchronously through the rotating shaft 2, and finally separates the material groove 1 from the outer periphery of the buffer paper roll. At this time, the wound buffer paper roll can be removed. After the wound buffer paper roll is removed, the push rod of the electric push rod retracts. Under the tension of the tension spring 5, the connecting rod 42 resets, and the material groove 1 resets to a horizontal state, preparing for the next winding. The electric push rod can make the material groove 1 quickly separate from the outer periphery of the buffer paper roll, and after the wound buffer paper roll is removed, the electric push rod can make the material groove 1 quickly reset to a horizontal state, ensuring the efficiency of winding. In other embodiments, the drive device 41 may also be a cylinder, a linear motor, or other structure that can drive the connecting rod 42 to move along the arcuate groove 31, as needed.

[0065] refer to Figures 1 to 3 A photoelectric sensor 7 can also be installed on the support plate 6. The photoelectric sensor 7 is connected to the electric push rod (drive 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 When the left side of the middle limit plate 3 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 switch 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 push rod stroke of the electric push rod does not need to be specially set or selected, as long as 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 post 62, the electric push rod stops working. After the wound-up buffer paper pad is unwound, the push rod of the electric push rod can be retracted directly.

[0066] The floating feed trough structure of this utility model is used in conjunction with a cushioning paper pad winding device. Continuous cushioning paper pads produced by an external cushioning paper pad machine can be conveyed to the cushioning paper pad winding device through feed trough 1. The cushioning paper pad winding device then winds up the continuous cushioning paper pads. (See reference...) Figures 1 to 4 When there is no cushioning paper pad on the feed trough 1, the feed trough 1 remains horizontal under the tension of the tension spring 5. When the cushioning paper pad winding device winds up a cushioning paper pad roll of a certain diameter, the outer circumference of the cushioning paper pad roll will push the feed trough 1 downward. When the feed trough 1 is subjected to the force of the cushioning paper pad roll, the feed trough 1 swings from a horizontal state to a non-horizontal state with the pivot 2 as the swing center. Since the tension spring 5 can drive the feed trough 1 to maintain the tendency to swing from a non-horizontal state to a horizontal state with the pivot 2 as the swing center, the tension spring 5 will drive the feed trough 1 to always be in close contact with the outer circumference of the cushioning paper pad roll during the winding process. Figure 7(As shown in the diagram) to ensure the tightness of the cushioning paper roll and prevent it from becoming loose during winding. The flange 12 on the feed trough 1 and the arc transition between the flange 12 and the feed trough 1 prevent the end of the feed trough 1 from getting stuck on the outer periphery of the cushioning paper roll. The flange 12, which is arranged at an obtuse angle to the feed trough 1, guides the cushioning paper roll to wind smoothly. After a roll of cushioning paper is wound, the tape-sticking mechanism of the cushioning paper roll winding device sticks the tape to the tail of the paper roll. As the cushioning paper roll winding device restarts for a certain period of time, the feed trough 1 remains in close contact with the tape on the outer periphery of the cushioning paper roll, thus ensuring that the tape is firmly adhered to the outer periphery of the cushioning paper roll and preventing the cushioning paper roll from unraveling. When the wound cushioning paper roll needs to be removed from the cushioning paper roll winding device, the drive device 41 drives the limit plate 3 to swing around the pivot 2 as the swing center. The limit plate 3 drives the feed trough 1 through the pivot 2. Synchronous oscillation separates the material trough 1 from the outer periphery of the cushioning paper roll, allowing the wound cushioning paper roll to be removed. This new floating material trough structure ensures that the material trough 1 remains tightly attached to the outer periphery of the cushioning paper roll regardless of whether the diameter of the cushioning paper roll wound by the cushioning paper roll winding device is the minimum or maximum. This guarantees consistent tightness of the cushioning paper roll wound by the cushioning paper roll from minimum to maximum diameter. The diameter of the cushioning paper roll wound by the cushioning paper roll can vary between the minimum and maximum diameters, allowing the wound cushioning paper roll to adapt to different carton sizes and better suited for cushioning packaging heavy items. The material trough 1 controls the tightness of the cushioning paper roll, ensuring consistent load-bearing capacity during the packing process, making packing more convenient and efficient for workers. It also ensures that the tape is firmly adhered to the outer periphery of the cushioning paper roll, preventing it from unraveling.

[0067] Figure 5 and Figure 6 The diagram schematically illustrates the structure of a buffer paper pad winding device according to one embodiment of the present invention.

[0068] refer to Figure 5 and Figure 6 A buffer paper pad winding device includes a winding mechanism 10, a floating feed trough structure, a controller, and a diffuse reflection sensor 100.

[0069] refer to Figure 5 and Figure 6The buffer paper pad winding device of this utility model is used in conjunction with the buffer paper pad machine 200 for making buffer paper pads. A tape-applying mechanism is installed below the discharge port 201 of the buffer paper pad machine 200. The tape-applying mechanism can be an existing automatic tape-applying device. The tape-applying mechanism is not the subject of this utility model's protection. One end of the material trough 1 is installed at the discharge port 201 of the buffer paper pad machine 200, and the other end of the material trough 1 is installed on the side of the winding mechanism 10. One end of the rotating shaft 2 is mounted on the bearing plate 6 via a bearing component 21. Figure 3 As shown), the other end of the rotating shaft 2 is also mounted in a fixed box 22 via a bearing component. Figure 3 As shown, the fixing box 22 is installed below the discharge port 201 of the cushioning paper pad machine 200. The material trough 1 can guide the cushioning paper pads produced by the cushioning paper pad machine 200 to the winding mechanism 10. The winding mechanism 10 can wind and rewind the cushioning paper pads produced by the cushioning paper pad machine 200.

[0070] refer to Figure 5 and Figure 6The winding mechanism 10 includes a turntable 20, a winding rod 30, a pusher plate 40, a first drive component 50, a second drive component 60, a crank-connecting rod mechanism 70, a guide rod 80, and a mounting plate 90. The ends of the winding rod 30 are fixed to the turntable 20. There are two winding rods 30, located at opposite ends of the turntable 20 in the diametrical direction. The first drive component 50 is mounted on the mounting plate 90 and drives the turntable 20 to rotate via a transmission mechanism consisting of two synchronous pulleys 501 and a synchronous belt (not shown). A torque motor is used. The pusher plate 40 is annular, with the inner diameter of the pusher plate 40 slightly larger than the outer diameter of the turntable 20. The pusher plate 40 is circumferentially arranged around the turntable 20. The guide rod 80 passes through a bushing in the mounting plate 90, with one end fixed to the pusher plate 40. The guide rod 80 can slide along its length on the mounting plate 90. The second drive component 60 is a motor, mounted on the mounting plate 90. The input end of the crank-connecting rod mechanism 70 is mounted on the shaft of the second drive component 60, and the output end of the crank-connecting rod mechanism 70 is fixed to the shaft. On the pusher plate 40, the second drive component 60 can drive the pusher plate 40 to move along the length direction of the winding rod 30 via the crank-connecting rod mechanism 70; the mounting plate 90 can support the first drive component 50, the second drive component 60, the turntable 20, and the pusher plate 40. The pusher plate 40 can smoothly reciprocate along the length direction of the winding rod 30 via the guide rod 80. When the shaft of the second drive component 60 (i.e., the motor) rotates one revolution, the crank-connecting rod mechanism 70 can drive the pusher plate 40 to roll out the buffer paper pad on the winding rod 30 and retract the pusher plate 40 to its original position. In addition, The tightness of the cushioning paper roll during the winding process can be adjusted by changing the speed of the torque motor (first drive component 50) and the output speed of the cushioning paper machine 400. For example, if the torque motor rotates faster and the output speed of the cushioning paper machine 200 is slower, the cushioning paper roll will be wound more tightly. If the torque motor rotates slower and the output speed of the cushioning paper machine 200 is faster, the cushioning paper roll will be wound more loosely. At the same time, under the action of the material trough 1, the winding mechanism 10 can wind out cushioning paper rolls with different tightness and different diameters, so that they can be better applied to the cushioning packaging of heavy objects.

[0071] refer to Figure 5 and Figure 6 There are three guide rods 80, which are arranged in a triangular pattern on the pusher plate 40. Under the driving action of the second drive component 60, the pusher plate 40 can move smoothly back and forth along the two winding rods 30. In other embodiments, the number of guide rods 80 can be adjusted as needed.

[0072] refer to Figure 5 and Figure 6A diffuse reflection sensor 100 is mounted on a mounting plate 90. The mounting plate 90 has a first through-hole 901 formed on it for the light emitted by the diffuse reflection sensor 100 to pass through. A second through-hole 401 is formed on the pusher plate 40 for the light emitted by the diffuse reflection sensor 100 to pass through. The diffuse reflection sensor 100 is located on the side of the turntable 20. The diffuse reflection sensor 100 determines the presence of material by emitting light and receiving light reflected back from objects, based on changes in the intensity of the received light. The diffuse reflection sensor 100 can detect whether there is a buffer paper pad on the feed trough 1. The diffuse reflection sensor 100 is connected to a controller (not shown) via a wiring harness. The controller can be a microcontroller or a single-chip microcomputer. The controller is connected to the first drive component 50 of the winding mechanism 10 through a wiring harness. The controller can control the first drive component 50 to start or stop working. When the starting end of the buffer paper pad on the feed trough 1 is delivered 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 delay, the controller controls the first drive component 50 to start working, and the winding rod 30 on the turntable 20 begins to wind and rewind the buffer paper pad.

[0073] Figure 7 and Figure 8 The schematic diagram illustrates the usage of the cushioning paper rewinding device shown in Figure 5.

[0074] refer to Figures 1 to 8 The continuous cushioning paper pads produced by the cushioning paper pad machine 200 are conveyed to the winding mechanism 10 through the discharge port 201 and the material trough 1. The tape pasting mechanism 300 is installed below the discharge port 201 of the cushioning paper pad machine 200. A window is provided 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 cushioning paper pad in the discharge port 201 through the window. A cutter is installed at the discharge port 201 of the cushioning paper pad machine 200. When there are no cushioning paper pads on the material trough 1, the material trough 1 remains horizontal under the tension of the tension spring 5. Figure 2 As shown in the diagram, when the starting end of the cushioning paper pad is detected by the diffuse reflection sensor 100, the controller delays for a certain period of time and then controls the first drive component 50 to start working. The winding rod 30 on the turntable 20 rotates clockwise to begin winding and rewinding the cushioning paper pad. When a cushioning paper pad roll 400 of a certain diameter is wound on the two winding rods 30, the outer periphery of the cushioning paper pad roll 400 will push the material trough 1 downward. When the material trough 1 is subjected to the force of the cushioning paper pad roll 400, the material trough 1 swings into a non-horizontal state. Figure 7As shown in the diagram, during the winding process, the tension spring 5 drives the material trough 1 to remain tightly pressed against the outer periphery of the cushioning paper roll 400, ensuring the tightness of the cushioning paper roll 400 and preventing it from becoming loose during winding. Simultaneously, the side guards 11 on both sides of the material trough 1 ensure that the end face of the cushioning paper roll 400 remains flat during winding, and the flanges 12 on the material trough 1 prevent the end of the material trough 1 from getting stuck on the outer periphery of the cushioning paper roll, guiding the cushioning paper roll to wind smoothly. When the outlet 201 of the cushioning paper machine 200 delivers a set length of cushioning paper, the cutter component at the outlet 201 of the cushioning paper machine 200 cuts the cushioning paper. When the two winding rods 30 are about to finish winding the set length of cushioning paper, the tape application mechanism 300 applies the tape. At the tail end of the wound cushioning paper roll 400, as the first drive component 50 restarts for a certain period of time, the material trough 1 remains firmly attached to the tape on the outer periphery of the cushioning paper roll 400. Then, the cutter component at the discharge port 201 of the cushioning paper roll machine 200 automatically or manually punctures or cuts the tape. The two winding rods 30 then wind up and firmly attach the remaining unattached tape on the cushioning paper roll 400. The tape is firmly attached and wrapped around the outer periphery of the cushioning paper roll 400. The winding of one cushioning paper roll 400 is completed. When it is necessary to remove the wound cushioning paper roll 400 from the winding rods 30, the drive device 41 drives the limiting plate 3 to swing around 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 separates from the outer periphery of the cushioning paper roll. Figure 8 (As shown in the diagram), 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 buffer paper roll 400 wound 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, preparing for the next push. In the buffer paper roll winding device of this utility model, regardless of whether the buffer paper roll wound by the winding mechanism 10 is the minimum diameter or the maximum diameter, the material groove 1 is always in close contact with the outer periphery of the buffer paper roll, that is, the buffer paper roll wound by the winding mechanism 10 is in close contact with the outer periphery of the buffer paper roll. The cushioning paper roll can maintain its tightness from the smallest to the largest diameter. The diameter of the cushioning paper roll wound by the winding mechanism 10 can be changed between the smallest and the largest diameter, so that the wound cushioning paper roll can be adapted to different carton sizes and can be better used for cushioning packaging of heavy objects. The material trough 1 can control the tightness of the cushioning paper roll, ensuring the consistency of the load-bearing capacity of the cushioning paper roll during the packing process, making it more convenient and efficient for operators to pack items. It can also ensure that the tape is firmly adhered to the outer periphery of the cushioning paper roll and prevent the cushioning paper roll from unraveling.

[0075] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
