[0037] See also Figures 1 to 5 This embodiment relates to a cradle air blowing device for a rewinder, wherein the cradle air blowing device for the rewinder includes a base 1, a paper unloading platform 2 rotatably mounted on the base 1, and an air blowing mechanism arranged on one side of the paper unloading platform 2 for preventing paper from sliding onto the paper unloading platform 2 in advance and being pressed by the paper roll.

[0038] The blowing mechanism includes an air pump 3 fixedly mounted on the base 1, a connecting pipe 4 fixedly mounted on the air pump 3, an electromagnetic valve 5 fixedly mounted on the connecting pipe 4, an air outlet pipe 6 fixedly mounted on the end of the connecting pipe 4 away from the air pump 3, a plurality of blowing holes 7 opened on the air outlet pipe 6 and a contact 8 electrically mounted on the paper unloading platform 2. The side surface of the air outlet pipe 6 is fixedly connected to one side of the paper unloading platform 2.

[0039] When the paper roll is in the paper unloading platform 2, the paper roll is pushed onto the paper unloading platform 2 by the force of the paper pushing roller. The paper unloading platform 2 starts to rotate immediately, and the paper roll rolls along the surface of the paper unloading platform 2. When the paper roll rolls to the middle position of the paper unloading platform 2, it will trigger the contact 8 when passing through the contact 8. After the contact 8 is triggered, the solenoid valve 5 will also be triggered. At this time, the air pump 3 starts to start. The gas blown by the air pump 3 will enter the interior of the air outlet pipe 6 through the connecting pipe 4, and then be discharged through multiple air holes 7. The discharged gas is facing the paper roll. The purpose of this is to prevent the paper from sliding onto the paper unloading platform 2 in advance due to the action of gravity, and thus being pressed underneath by the paper roll, thereby reducing the probability of waste paper. The operation is simple, the structure is simple, the workload of the operator is reduced, time and effort are saved, and work efficiency is improved.

[0040] Optionally, in some embodiments, Figures 1 to 3 As shown, the blowing holes 7 are distributed in a linear array on the air outlet pipe 6 to ensure that the discharged gas is facing the paper roll; a plurality of first support frames 9 are fixedly connected to the top of the base 1, and the base 1 is fixedly connected to the top plate 10 through the first support frames 9. Specifically, in this embodiment, as Figures 1 to 3 As shown, there are two first support frames 9, and the two first support frames 9 are respectively arranged on the left and right sides of the base; it should be noted that, in this embodiment, the number of first support frames 9 is not limited. In other embodiments, the first support frames 9 can be three or four.

[0041] Optionally, in some embodiments, Figures 1 to 3 As shown, in order to facilitate the rotation of the paper unloading platform 2, the rewinder cradle blowing device also includes a pushing mechanism, one end of the pushing mechanism is connected to the top plate 10, and the other end of the pushing mechanism is connected to the paper unloading platform 2. The pushing mechanism is used to push the paper unloading platform 2 to gradually change the inclination angle of the paper unloading platform 2, thereby facilitating the rotation of the paper unloading platform 2.

[0042] Specifically, in this embodiment, Figures 1 to 3As shown, the pushing mechanism includes two electric push rods 11, one end of each of the two electric push rods 11 is hinged to the bottom of the top plate 10, and the other end (movable end) of each of the two electric push rods 11 is movably connected to both sides of the paper unloading platform 2. In other embodiments, the electric push rods in this embodiment can also be replaced by oil cylinders or air cylinders.

[0043] Specifically, in this embodiment, Figures 1 to 3 As shown, when the cradle blowing device of the rewinding machine is in use, first, the electric push rod 11 is started, and then the movable end of the electric push rod 11 begins to move, and the movement of the movable end further pushes the paper unloading platform 2, so that it begins to rotate with the position where it is connected to the base 1 as the center of the circle, and the paper unloading platform 2 gradually changes its inclination angle under the push of the electric push rod 11 until it reaches an angle that is completely flush with the paper pushing roller. At this time, the start of the electric push rod 11 is stopped. After the rewinding machine successfully completes the rewinding work, the rewound paper roll will be pushed onto the paper unloading platform 2 with the help of the pushing action of the paper pushing roller. Subsequently, by starting the electric push rod 11, the movable end of the electric push rod 11 will move toward the opposite direction The paper roll is moved in the opposite direction, and the reverse movement of the electric push rod 11 will produce a driving effect, so that the paper unloading platform 2 takes the position where it is connected to the base 1 as the center of the circle and rotates in the opposite direction. During the rotation of the paper unloading platform 2, the paper roll rolls along the surface of the paper unloading platform 2 until the contact 8 is triggered, and the solenoid valve 5 is triggered by the contact 8. At this time, the air pump 3 is started, and the air blown by the air pump 3 enters the interior of the air outlet pipe 6 through the connecting pipe 4, and blows air to the paper roll through the multiple blowing holes 7 to prevent the paper from sliding onto the paper unloading platform 2 in advance due to gravity and being pressed underneath by the paper roll, thereby reducing the probability of waste paper. The operation is simple, the structure is simple, the workload of the operator is reduced, time and effort are saved, and work efficiency is improved.

[0044] Optionally, in some embodiments, Figures 1 to 5 As shown, in order to cushion the paper unloading platform 2 when it rotates in the opposite direction to the bottom along the position where the paper unloading platform 2 is connected to the base 1 as the center of the circle, the rewinder cradle blowing device also includes a buffer mechanism 100, and the buffer mechanism 100 is arranged at the bottom of the paper unloading platform 2. The buffer mechanism 100 is used to cushion and protect the paper unloading platform 2, thereby protecting the paper unloading platform.

[0045] Specifically, in this embodiment, Figures 1 to 5As shown, the buffer mechanism 100 includes a telescopic rod 12 and an elastic component; the ends of the telescopic rod 12 are fixedly connected to an upper baffle 16 and a lower baffle 17, respectively. The telescopic rod 12 is disposed between the top of the base 1 and the bottom of the paper unloading platform 2; the elastic component is sleeved on the side surface of the telescopic rod 12, with one end of the elastic component connected to the upper baffle 16 and the other end of the elastic component connected to the lower baffle 17. It should be noted that the structure of the buffer mechanism 100 of this embodiment is not limited to this embodiment, and those skilled in the art may select other suitable buffer mechanisms 100 based on the teachings of this embodiment.

[0046] Preferably, in this embodiment, Figures 1 to 5 As shown, the elastic component is a spring 13 , one end of the spring 13 is fixedly connected to the top of the lower baffle 17 , and the other end of the spring 13 is fixedly connected to the bottom of the upper baffle 16 .

[0047] Specifically, in this embodiment, Figures 1 to 5 As shown, when the cradle blowing device of the rewinder is in use, after the rewinder completes the rewinding task, the paper roll will be smoothly pushed to the paper unloading platform 2 via the paper pushing roller. At this time, by starting the electric push rod 11, its movable end will move in the opposite direction to the previous direction. This movement will pull the paper unloading platform 2 and make it rotate in the opposite direction around the connection point with the base 1. When the paper unloading platform 2 rotates to a state completely parallel to the base 1, its bottom will first come into contact with the upper baffle on the telescopic rod 12. Subsequently, the paper unloading platform 2 will apply a certain pressure to the upper baffle, thereby compressing the spring 13 and causing the telescopic rod 12 to shorten. The spring 13, by virtue of its elastic potential energy, generates an upward elastic force on the upper baffle, thereby effectively achieving buffering protection for the paper unloading platform 2.

[0048] Optionally, in some embodiments, Figures 1 to 5 As shown, a second support frame 14 is fixedly connected to the paper unloading platform 2 , and a blocking rod 15 is fixedly connected to the paper unloading platform 2 through the second support frame 14 to prevent the paper roll from rolling off the paper unloading platform 2 .

[0049] Specifically, in this embodiment, Figures 1 to 5As shown, when the rewinding machine cradle blower device is in use, after the rewinding machine successfully completes the rewinding operation, the paper roll is pushed onto the paper unloading platform 2 with the help of the paper pushing roller. Next, the electric push rod 11 is started. At this time, the movable end of the electric push rod 11 begins to move in the opposite direction. Due to this reverse movement of the electric push rod 11, the paper unloading platform 2 will rotate in the opposite direction with the position where it is connected to the base 1 as the center of the circle, so that the paper roll will roll along the surface of the paper unloading platform 2. When the paper unloading platform 2 rotates to a state parallel to the base 1, the paper roll on the paper unloading platform 2 rolls to the bottom of the paper unloading platform 2. At this time, the second support frame 14 and the baffle 15 will play a role to block the paper roll and prevent the paper roll from rolling off the paper unloading platform 2. After the second support frame 14 and the baffle 15 successfully block the paper roll, the operator can take out the paper roll.

[0050] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
