Description

Technical Field

[0001] The invention relates to a floating trough structure for winding a buffer paper pad and a buffer paper pad winding device. Background Art

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

[0003] The existing paper cushioning equipment produces paper cushions in sections, which do not have a good cushioning and packaging effect during the packing of heavy objects. Packers need to manually arrange the paper cushions into cartons in a certain manner to cushion the packed heavy objects. This method is labor-intensive and the cushioning effect of the manually stacked paper cushions is less consistent.

[0004] At present, the buffer paper pad rewinding rack can rewind continuous buffer paper pads into a roll, but the diameter of the rewound buffer paper pad roll is basically fixed or has only a few specific diameters, which has poor applicability and cannot adapt to different carton sizes. Moreover, the tightness of the rewound buffer paper pad roll is also poor, and is generally looser than expected. Usually, the operator needs to adjust the tightness and then fix it with tape. The tape fixing method is usually: the tape sticking equipment sticks the tape to the tail of the paper pad of the buffer paper pad roll, and as the buffer paper pad rewinding rack is started again for a certain period of time, the tape can be stuck and wound on the outer periphery of the buffer paper pad roll. However, in this way, the firmness of the tape stuck to the outer periphery of the buffer paper pad roll is difficult to ensure. If the buffer paper pad roll is rolled tightly, the tape will be firmly stuck to the outer periphery of the buffer paper pad roll. If the buffer paper pad roll is rolled loosely, the tape is difficult to firmly stick to the outer periphery of the buffer paper pad roll, resulting in the buffer paper pad roll being loose and unable to meet the rewinding requirements.

[0005] Therefore, how to overcome the above technical deficiencies is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] The object of the present invention is to provide a floating trough structure for winding a buffer paper pad and a buffer paper pad winding device to solve at least one of the above-mentioned technical problems.

[0007] According to one aspect of the present invention, a floating trough structure for winding a buffer paper pad is provided, comprising:

[0008] trough;

[0009] The rotatable shaft has one end of the trough fixed on it.

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

[0011] A limit plate, which is fixed on the rotating shaft;

[0012] A driving mechanism capable of driving the limit plate to swing with the rotating shaft as the swing center; and

[0013] The reset component can drive 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.

[0014] The floating material 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 material trough. The buffer paper pad winding device winds up the continuous buffer paper pad. When there is no buffer paper pad on the material trough, the material trough is kept in a horizontal state under the action of the reset component. 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 material trough downward. When the material trough is subjected to the force of the buffer paper pad roll, the material trough swings from a horizontal state to a non-horizontal state with the rotating shaft as the swing center. The resetting component drives the material trough to maintain a tendency to swing from a non-horizontal state to a horizontal state with the rotating shaft as the swing center. Therefore, during the rewinding process of the buffer paper pad rewinding device, the resetting component will drive the material 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 rewinding process. When a roll of buffer paper pad is rewound, the tape-sticking mechanism of the buffer paper pad rewinding device sticks the tape to the tail of the paper pad of the buffer paper pad roll. As the buffer paper pad rewinding device is started again for a certain period of time, the material trough is always in close contact with the tape on the outer periphery of the buffer paper pad roll, thereby Ensure that the adhesive tape is firmly adhered and wrapped around the outer periphery of the buffer paper pad roll to prevent the buffer paper pad roll from unraveling. When the rolled-up buffer paper pad roll needs to be removed 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 material trough to swing synchronously through the rotating shaft to separate the material trough from the outer periphery of the buffer paper pad roll. At this time, the rolled-up buffer paper pad roll can be removed. With the floating material trough structure of the present invention, no matter whether the buffer paper pad roll rolled up by the buffer paper pad winding device is of the minimum diameter or the maximum diameter, the material trough is tightly attached to the outer periphery of the buffer paper pad roll, that is, the buffer paper pad winding device is wound The cushioning paper pad roll can be wound with guaranteed tightness from the minimum diameter to the maximum diameter. The diameter of the cushioning paper pad roll wound by the cushioning paper pad winding device can be changed between the minimum diameter and the maximum diameter, so that the wound cushioning paper pad roll can adapt to different carton sizes and can be better used in the cushioning packaging of heavy objects. The material trough can control the tightness of the cushioning paper pad roll, ensuring the consistency of the load-bearing capacity of the cushioning paper pad roll during the packaging process, making it more convenient and efficient for operators to pack items, and ensuring that the tape is firmly adhered and wrapped around the outer circumference of the cushioning paper pad roll to prevent the cushioning paper pad roll from spreading.

[0015] In some embodiments, a bearing plate may be further included, wherein the rotating shaft is inserted into the bearing plate and can rotate on the bearing plate.

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

[0017] When the trough is subjected to the force of the buffer paper pad roll, the trough will swing from the horizontal state to the non-horizontal state with the rotating shaft as the swing center. In a flat state, during the winding process of the buffer paper pad winding device, under the tension of the tension spring, the material trough is always 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 pad is wound, the tape pasting mechanism of the buffer paper pad winding device sticks the tape to the tail of the paper pad of the buffer paper pad roll. As 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 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.

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

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

[0020] When the roll of buffer paper pad is removed, the driving device drives the connecting rod to reset, and the reset component drives the material trough to reset to the horizontal state, preparing for the next winding.

[0021] In some embodiments, the driving device may be an electric linear actuator.

[0022] Therefore, when the material trough swings from a horizontal state to a non-horizontal state, the material trough drives the limit plate to swing synchronously through the rotating shaft, and the arc groove on the limit plate moves along the connecting rod, that is, the connecting rod moves from the first end of the arc groove to the second end of the arc groove. After the buffer paper pad roll is wound, the push rod of the electric push rod extends, and the push rod of the electric push rod drives the connecting rod to move in the arc groove toward the first end of the arc groove. When the connecting rod moves to the first end of the arc groove, the connecting rod drives the limit plate to swing, and the limit plate drives the limit plate through the rotating shaft The material trough swings synchronously, and finally separates the material trough from the outer periphery of the buffer paper pad roll. At this time, the rolled buffer paper pad roll can be removed. After the rolled buffer paper pad roll is removed, the push rod of the electric push rod retracts, the connecting rod resets, and the reset component drives the material trough to reset to a horizontal state, preparing for the next winding. The electric push rod can quickly separate the material trough from the outer periphery of the buffer paper pad roll, and after removing the rolled buffer paper pad roll, the electric push rod can quickly reset the material trough to a horizontal state to ensure the efficiency of winding.

[0023] In some embodiments, the driving mechanism may further include a bearing and two clamping plates, the bearing being arranged on the other end of the connecting rod, the bearing being accommodated in the arc groove, the clamping plate being provided with a limit groove, the two clamping plates being respectively arranged on both sides of the limit plate, the connecting rod being inserted into a limit groove and being able to move along the limit groove, and the width of the limit groove being smaller than the width of the arc groove.

[0024] As a result, 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 splints can limit the bearing in the arc groove of the limit plate to prevent the bearing from falling out.

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

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

[0027] When the second side of the carrying plate abuts against the second limiting column, the trough is in a vertical state.

[0028] The first side and the second side of the carrying plate are arranged vertically.

[0029] Therefore, the first limit column and the second limit column can limit the swing angle of the limit plate. Since the limit plate is fixed on the rotating shaft and one end of the material trough is also fixed on the rotating shaft, the first limit column and the second limit column 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 trough may be provided with ribs on both sides along its length.

[0031] Therefore, the ribs on both sides of the trough can ensure that the end surface of the buffer paper pad roll remains flat during the winding process, thereby ensuring the winding quality of the buffer paper pad.

[0032] According to another aspect of the present invention, a buffer 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 buffer paper pad machine for making buffer paper pads, and the other end of the material trough is arranged on the side of the winding mechanism. The material trough can guide the buffer paper pad made by the buffer paper pad machine to the winding mechanism, and the winding mechanism can wind and reel the buffer paper pad made by the buffer paper pad machine.

[0033] The buffer paper pad winding device of the present invention is characterized in that the continuous buffer paper pad made by the external buffer paper pad machine is sent out through the discharge port of the buffer paper pad machine, and the continuous buffer paper pad is transported to the winding mechanism through the material trough. The winding mechanism can wind up the continuous buffer paper pad. When there is no buffer paper pad on the material trough, the material trough is kept in a horizontal state under the action of the reset component. When a buffer paper pad roll with a certain diameter is wound on the winding mechanism, the outer periphery of the buffer paper pad roll will push the material trough downward. When the material trough is subjected to the force of the buffer paper pad roll, the material trough is swung by the water around the rotating shaft as the center of the swing. The flat state swings into a non-horizontal state. During the rewinding process, the reset component will drive the material 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 rewinding process. When a roll of buffer paper pad is completed, the tape-pasting mechanism of the buffer paper pad rewinding device sticks the tape to the tail of the paper pad of the buffer paper pad roll. As the buffer paper pad rewinding device starts again for a certain period of time, the material 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 stuck and wound around the buffer paper pad. The outer periphery of the roll is used to prevent the buffer paper pad roll from spreading. When the rolled-up buffer paper pad roll needs to be taken off the roll-up mechanism, the driving mechanism drives the limit plate to swing with the rotating shaft as the swing center, and the limit plate drives the material trough to swing synchronously through the rotating shaft to separate the material trough from the outer periphery of the buffer paper pad roll. At this time, the rolled-up buffer paper pad roll can be taken off. The buffer paper pad winding device of the present invention, no matter the buffer paper pad roll rolled by the winding mechanism is of the minimum diameter or the maximum diameter, the material trough is in close contact with the outer periphery of the buffer paper pad roll, that is, the buffer paper pad roll rolled by the winding mechanism is from the minimum diameter To the maximum diameter, the tightness can be guaranteed. The diameter of the buffer paper pad roll rolled up by the winding mechanism can be changed between the minimum diameter and the maximum diameter, so that the rolled buffer paper pad roll can adapt to different carton sizes and can be better used in the cushioning packaging of heavy objects. The material 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 packaging process, making it more convenient and efficient for operators to pack items, and ensuring that the tape is firmly attached and wrapped around the outer circumference of the buffer paper pad roll to prevent the buffer paper pad roll from spreading.

[0034] In some embodiments, the winding mechanism may include a turntable, a winding rod, a pushing plate, a first driving component and a second driving component. The winding rod is arranged on the turntable, the first driving component drives the turntable to rotate, the pushing plate is arranged on the periphery of the turntable, and the second driving component can drive the pushing 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 reel in the buffer paper pad. After the reeling is completed, under the action of the second driving component, the pushing plate moves along the length direction of the winding rod. The pushing plate can push the rolled buffer paper pad off the winding rod, and then under the action of the second driving component, the pushing plate is retracted along the length direction of the winding rod to reset it, preparing for the next pushing.

[0036] In some embodiments, the winding mechanism may further include a crank-connecting rod mechanism, a guide rod, and a mounting plate, wherein the first driving component and the second driving component are both disposed on the mounting plate.

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

[0038] The first drive component is a torque motor,

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

[0040] Therefore, the mounting plate can carry the first driving component, the second driving component, the turntable, and the pushing plate. The pushing plate can move back and forth smoothly along the length direction of the winding rod through the guide rod. The rotating shaft of the motor rotates one circle, and the crank-connecting rod mechanism can drive the pushing plate to push out the buffer paper pad roll on the winding rod and retract the pushing plate to its original position. In addition, the tightness of the buffer paper pad roll during the winding process can also be achieved by adjusting the speed of the torque motor and the discharge speed of the buffer paper pad machine. For example: if the torque motor rotates fast and the discharge speed of the buffer paper pad machine is slow, the buffer paper pad roll will be wound tighter; if the torque motor rotates slowly and the discharge speed of the buffer paper pad machine is fast, the buffer paper pad roll will be wound looser. At the same time, under the action of the material trough, the winding mechanism 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.

[0041] In some embodiments, the device may further include a controller and a diffuse reflection sensor, wherein the diffuse reflection sensor is disposed 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.

[0042] The diffuse reflection sensor can detect whether there is a buffer paper pad on the material 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 material trough is transported to the side position of the winding mechanism, the starting end of the buffer paper pad will be detected by the diffuse reflection sensor, and the diffuse reflection sensor will send the detected signal to the controller. After a certain delay, the controller controls the winding mechanism to start working, and the winding mechanism starts to wind the buffer paper pad. BRIEF DESCRIPTION OF THE DRAWINGS

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features referred to.

[0054] Figures 1 to 4 The structure of a floating trough structure for winding a buffer paper pad according to an embodiment of the present invention is schematically shown.

[0055] refer to Figures 1 to 4 A floating trough structure for winding a cushioning paper pad includes a trough 1, a rotating shaft 2, a limiting plate 3, a driving mechanism, and a reset component. In addition, the floating trough structure may also include a bearing plate 6.

[0056] refer to Figures 1 to 3 One end of the material trough 1 is fixed on the rotating shaft 2, and the material trough 1 is formed with a rib 11 on both sides along its length direction. The rib 11 can be formed by bending the two sides of the material trough 1 90 degrees. The ribs 11 on both sides of the material trough 1 can ensure that the end surface of the buffer paper pad roll remains flat during the winding process, thereby ensuring the winding quality of the buffer paper pad.

[0057] refer to Figure 1 and Figure 3 The rotating shaft 2 is inserted into the supporting plate 6 , and the rotating shaft 2 can rotate on the supporting plate 6 . Specifically, the rotating shaft 2 can be installed on the supporting plate 6 through a bearing component 21 so that the rotating shaft 2 can rotate on the supporting plate 6 .

[0058] refer to Figures 1 to 3 The corner of the limit 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 of the limit plate 3, and the bearing plate 6 is located between the trough 1 and the limit plate 3. The limit plate 3 can swing synchronously with the trough 1 through the rotating shaft 2 with the rotating shaft 2 as the swing center. When the trough 1 is subjected to external force, such as Figure 2 The external force F in the trough 1 and the limit plate 3 can swing from the horizontal state ( Figure 1 state) swings into a non-horizontal state ( Figure 7 state), the supporting plate 6 can support the rotating shaft 2 and the material trough 1.

[0059] The reset component can drive the 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. Specifically, in this embodiment, with reference 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 limit plate 3. When there is no buffer paper pad on the trough 1, under the tension of the tension spring 5, the limit plate 3 maintains a tendency to swing with the rotating shaft 2 as the swing center, that is, Figure 2 The middle limit plate 3 keeps a tendency to swing counterclockwise with the rotating shaft 2 as the swing center. The limit plate 3 drives the trough 1 to keep a tendency to swing from a non-horizontal state to a horizontal state with the rotating shaft 2 as the swing center through the rotating shaft 2, so that the trough 1 is kept in a horizontal state ( Figure 2 status shown), Figure 7 When a certain diameter of buffer paper pad roll is rolled up on the reeling mechanism of the buffer paper pad reeling device, the outer periphery of the buffer paper pad roll will push the trough 1 downward. When the trough 1 is subjected to the force of the buffer paper pad roll, the trough 1 will swing from a horizontal state ( Figure 2 shown) swings into a non-horizontal state ( Figure 7 The state shown), during the process of winding the buffer paper pad, the material trough 1 will always be in close contact with the outer periphery of the buffer paper pad roll under the tension of the tension spring 5, thereby 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, the tape pasting 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 winding mechanism of the buffer paper pad winding device is started again for a certain period of time, the material trough will always be 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.

[0060] refer to Figure 1 and Figure 2 , the first limiting column 61 and the second limiting column 62 are installed on the bearing plate 6. 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 column 61 ( Figure 2 The trough 1 is in a horizontal state, when the second side of the limiting plate 3 ( Figure 2 When the left side of the middle limiting plate 3 rests on the second limiting post 62, the trough 1 is in a vertical state, and the first side and the second side of the limiting plate 3 are arranged vertically. 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 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 trough 1. For example, if the swing angle of the trough 1 is 0 to 90 degrees, the trough 1 can be swung 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 supporting plate 6, 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 column 62, the trough 1 can also be in a state close to vertical and non-vertical ( Figure 8 status shown).

[0061] 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 limit plate 3 to swing. An arc groove 31 is formed on the limit plate 3. One end of the connecting rod 42 is fixed on the driving rod 411 of the driving device 41, and 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 groove 31, that is, the other end of the connecting rod 42 is accommodated in the arc groove 31 through the bearing 43. The driving device 41 can drive the connecting rod 42 to move along the arc groove 31, and the connecting rod 42 drives the bearing 43 to roll in the arc groove 31. The connecting rod 42 can move smoothly in the arc groove 31 through the bearing 43. The two clamping plates 44 are respectively fixed on both sides of the limiting plate 3, and 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 groove 31 of the limiting plate 3 to prevent the bearing 43 from falling out; when the material trough 1 swings from the horizontal state to the non-horizontal state, the material trough 1 drives the limiting plate 3 to swing synchronously through the rotating shaft 2, and the arc groove 31 on the limiting plate 3 moves along the bearing 43, that is, the bearing 43 moves from the first end ( Figure 1 The position of the middle bearing 43) to the second end ( Figure 2 When the buffer paper roll is wound up, the driving device 41 drives the bearing 43 in the arc groove 31 through the connecting rod 42 to move toward the first end of the arc groove 31. When the bearing 43 moves to the first end of the arc groove 31, the bearing 43 and the connecting rod 42 drive the limit plate 3 to swing. The swing direction is Figure 2 In the clockwise direction, the limit plate 3 drives the trough 1 to swing synchronously through the rotating shaft 2, and the swing direction of the trough 1 is still from the horizontal state to the non-horizontal state. Figure 2 In the clockwise direction, the material trough 1 is finally separated from the outer periphery of the buffer paper roll ( Figure 8The wound cushion paper roll can now be removed. Once the rolled cushion paper roll is removed, the drive device 41 resets the connecting rod 42, which in turn resets the bearing 43. Under the tension of the tension spring 5, the trough 1 returns to a horizontal position, ready for the next rewind. Furthermore, the length of the arcuate slot 31 determines the swing angle of the limit plate 3 and the trough 1. Adjusting the length of the arcuate slot 31 can adjust the swing angle of the limit plate 3 and the trough 1 as needed.

[0062] refer to Figures 1 to 4 In this embodiment, the driving device 41 is an electric push rod. When the trough 1 swings from a horizontal state to a non-horizontal state, the trough 1 drives the limit plate 3 to swing synchronously through the rotating shaft 2. The arc groove 31 on the limit plate 3 moves along the connecting rod 42, that is, the connecting rod 42 moves from the first end of the arc groove 31 ( Figure 1 The position of the middle bearing 43) to the second end ( Figure 2 The upper end of the middle arc groove 31 moves in the direction of the buffer paper roll. After the buffer paper roll is wound up, the material trough 1 is in a non-horizontal state ( Figure 7 When the chute 1 is lifted up, the chute 1 is retracted and the chute 1 is retracted to the horizontal position so that the chute 1 is retracted. In other embodiments, as needed, the driving device 41 may also be a cylinder, a linear motor, or other structures that can drive the connecting rod 42 to move along the arc groove 31.

[0063] refer to Figures 1 to 3 , a photoelectric sensor 7 can also be installed on the carrier plate 6, and 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 When the left side of the middle limit plate 3 abuts against the second limit column 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 stroke of the push rod 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 limiting plate 3 abuts against the second limiting column 62, the electric push rod stops working. When the rolled-up buffer paper pad is taken down, the push rod of the electric push rod can be directly retracted.

[0064] 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 trough 1, the 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 wound on the buffer paper pad winding device, the outer periphery of the buffer paper pad roll will push the trough 1 downward. When the trough 1 is subjected to the force of the buffer paper pad roll, the 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 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 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 paper pad is then unwound and the roll is then unwound, ... The floating material trough structure of the invention is such that no matter whether the buffer paper pad roll wound by the buffer paper pad winding 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 wound by the buffer paper pad winding 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 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 used in the cushioning 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.

[0065] Figure 5 and Figure 6The structure of a buffer paper pad winding device according to an embodiment of the present invention is schematically shown.

[0066] refer to Figure 5 and Figure 6 A buffer paper pad winding device includes a winding mechanism 10, a floating material trough structure, a controller and a diffuse reflection sensor 100.

[0067] refer to Figure 5 and Figure 6 The buffer paper pad winding device of the present invention is used in conjunction 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 an existing automatic tape pasting device. The tape pasting mechanism is not the object of protection of the present invention. 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 installed on the supporting plate 6 through the bearing component 21 ( Figure 3 As shown), the other end of the shaft 2 is also mounted in a fixed box 22 through a bearing component ( Figure 3 As shown), the fixed box 22 is installed below the discharge port 201 of the buffer paper pad machine 200, and the material trough 1 can guide the buffer paper pad produced by the buffer paper pad machine 200 to the winding mechanism 10, and the winding mechanism 10 can wind and reel the buffer paper pad produced by the buffer paper pad machine 200.

[0068] refer to Figure 5 and Figure 6The winding mechanism 10 includes a turntable 20, a winding rod 30, a pushing 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 diameter direction of the turntable 20. 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 used, the pusher disc 40 is annular, the inner diameter of the pusher disc 40 is slightly larger than the outer diameter of the turntable 20, the pusher disc 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 pusher disc 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, and 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 the rotating shaft of the second driving component 60. On the pushing disc 40, the second driving component 60 can drive the pushing disc 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 pushing disc 40. The pushing disc 40 can move back and forth smoothly 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 pushing disc 40 to push out the buffer paper pad on the winding rod 30 and retract and reset the pushing disc 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 fast and the discharge speed of the buffer paper pad machine 200 is slow, the winding of the buffer paper pad roll will be tighter; if the torque motor rotates slowly and the discharge speed of the buffer paper pad machine 200 is fast, the winding of the buffer paper pad roll will be looser. At the same time, under the action of the material trough 1, the winding mechanism 10 can wind out buffer paper pad rolls of different tightness and diameters, so that it can be better used in the cushioning packaging of heavy objects.

[0069] refer to Figure 5 and Figure 6 The number of guide rods 80 is three, and the three guide rods 80 are arranged in a triangle on the pusher tray 40. Under the driving action of the second driving component 60, the pusher tray 40 can move back and forth smoothly along the two winding rods 30. In other embodiments, the number of guide rods 80 can be adjusted as needed.

[0070] refer to Figure 5 and Figure 6The diffuse reflection sensor 100 is mounted 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 push 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 on the side of the turntable 20. The diffuse reflection sensor 100 emits light and receives light reflected back by the object, and determines the presence of the material according to the change in the intensity of the received light. The diffuse reflection sensor 100 can detect whether there is a buffer paper pad on the material trough 1. The diffuse reflection sensor 100 is connected to the controller (not shown) through a wiring harness. The controller 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 material trough 1 is transported 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 perforation 901 and the second perforation 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 starts to wind and reel the buffer paper pad.

[0071] Figure 7 and Figure 8 Schematically shows Figure 5 The buffer paper pad winding device is shown in use.

[0072] refer to Figures 1 to 8 The continuous buffer paper pad produced by the buffer paper pad machine 200 is transported to the winding mechanism 10 through the discharge port 201 and the material trough 1. The adhesive tape pasting mechanism 300 is installed below the discharge port 201 of the buffer paper pad machine 200. A window is provided below the discharge port 201. A tape roll 301 is installed below the adhesive tape pasting mechanism 300. The adhesive 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 cutting 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 trough 1, the material trough 1 is kept in a horizontal state under the tension of the tension spring 5 ( Figure 2 When the starting end of the buffer paper pad is detected by the diffuse reflection sensor 100, the controller controls the first driving component 50 to start working after a certain delay, and the winding rod 30 on the turntable 20 rotates clockwise to start winding the buffer paper pad. When the two winding rods 30 are wound with a buffer paper pad roll 400 of a certain diameter, the outer periphery of the buffer paper pad roll 400 will push the material trough 1 downward. When the material trough 1 is subjected to the force of the buffer paper pad roll 400, the material trough 1 swings into a non-horizontal state ( Figure 7The 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 retaining edges 11 on both sides of the material trough 1 can ensure that the end surface of the buffer paper pad roll 400 remains flat during the winding process. After the discharge port 201 of the buffer paper pad machine 200 sends out the set length of buffer paper pad, the cutter component at the discharge port 201 of the buffer paper pad machine 200 cuts off the buffer paper pad. When the two winding rods 30 are about to complete the winding of the set length of buffer paper pad, the tape pasting mechanism 300 pastes the tape on the tail of the paper pad of the wound buffer paper pad roll 400. The first driving component 50 is started again for a certain period of time, and the material trough 1 is always in close contact with the tape on the outer periphery of the buffer paper pad roll 400, and then the cutter component at the discharge port 201 of the buffer paper pad machine 200 automatically or manually punctures or cuts the tape, and the two winding rods 30 roll up the remaining unpasted tape on the buffer paper pad roll 400, and the tape is firmly adhered and wound around the outer periphery of the buffer paper pad roll 400. The winding of a roll of buffer paper pad roll 400 is completed. When the wound buffer paper pad roll 400 needs to be removed 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, and 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 The state shown), then under the driving action of the second driving component 60, the pushing plate 40 moves along the length direction of the winding rod 30, and the pushing plate 40 can push the buffer paper pad roll 400 wound on the winding rod 30 out of the winding rod 30, and then the pushing plate 40 is retracted along the length direction of the winding rod 30 to reset and prepare for the next material pushing; the buffer paper pad winding device of the present invention, no matter whether the buffer paper pad roll wound by the winding mechanism 10 is of 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 wound by the winding mechanism 10 The tightness of the roll can be guaranteed from the minimum diameter to the maximum diameter. The diameter of the buffer paper pad roll rolled up by the rolling mechanism 10 can be changed between the minimum diameter and the maximum diameter, so that the rolled up buffer paper pad roll can adapt 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 buffer paper pad roll, ensuring the consistency of the load-bearing capacity of the buffer paper pad roll during the packaging process, making it more convenient and efficient for operators to pack items, and ensuring that the tape is firmly adhered and wrapped around the outer periphery of the buffer paper pad roll to prevent the buffer paper pad roll from spreading.
