It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-4 As shown, this utility model embodiment provides a rewinding device for nano double-sided adhesive with adjustable winding diameter, including a support plate 1 and a mounting plate 2, as well as a connecting frame 3, a blocking block 4, a fixing pin 5, a moving block 6, a buffer spring 7, a buffer rod 8, a buffer sheet 9, a first contact plate 10, a blocking plate 11, and an auxiliary mechanism.

[0031] like Figure 3As shown, the connecting frame 3 is installed on the upper surface of the mounting plate 2. A blocking block 4 is slidably connected inside the connecting frame 3. A fixing pin 5 is threaded through the outer side of the blocking block 4. The fixing pin 5 is slidably connected inside the connecting frame 3. A moving block 6 is slidably connected inside the connecting frame 3. A circular hole is opened on the upper surface of the connecting frame 3. The circular hole allows the buffer rod 8 to pass through during the upward movement of the buffer rod. A buffer spring 7 is installed on the upper surface of the moving block 6. A buffer rod 8 is installed on the upper surface of the moving block 6. The outer surface of the buffer rod 8 passes through the buffer spring 7. A buffer plate 9 is installed at the top of the buffer spring 7. The outer surface of the buffer rod 8 passes through the buffer plate 9. The outer surface of the buffer rod 8 passes through the blocking block 4. When the blocking block 4 is adjusted, it needs to move along the inside of the connecting frame 3 and the outer surface of the buffer rod 8. A first contact plate 10 is installed on the inner side of the moving block 6. A blocking plate 11 is installed on the upper surface of the first contact plate 10. The auxiliary mechanism is set inside the mounting plate 2.

[0032] like Figure 4 As shown, the auxiliary mechanism includes a connecting shaft 12, a controller 13, and a movable frame 14. The connecting shaft 12 is rotatably connected to the mounting plate 2. The controller 13 is mounted on the upper surface of the support plate 1. The movable frame 14 is slidably connected to the interior of the mounting plate 2. The movable frame 14 moves downward along the interior of the mounting plate 2, which can move the first transmission gear 16 downward and disengage it from the second transmission gear 17, so that the connecting shaft 12 stops winding the tape. A drive motor 15 is mounted on the upper surface of the movable frame 14. The drive motor 15 is divided into two groups, front and rear. The drive motor 15 on the front side rotates in reverse during use, and the drive motor 15 on the rear side rotates in forward during use. Therefore, the connecting shaft 12 can rotate in the same direction. The output end of the drive motor 15 is equipped with the first transmission gear 16, and the outer end of the connecting shaft 12 is sleeved with the second transmission gear 17. The first transmission gear 16 and the second transmission gear 17 mesh. The output end of the controller 13 is connected to the drive motor 14. The input end of 5 is electrically connected. A push rod motor 18 is installed on the upper surface of the support plate 1. The output end of the push rod motor 18 is installed on the lower surface of the moving frame 14. A fixed tube 19 is installed on the upper surface of the support plate 1. A fixed spring 20 is installed inside the fixed tube 19. A moving rod 21 is installed at the top of the fixed spring 20. The moving rod 21 passes through the fixed tube 19. The top of the moving rod 21 is installed on the lower surface of the moving frame 14. A sensor 29 is installed inside the blocking block 4. The sensor 29 is a common infrared sensor on the market. The blocking plate 11 moves upward to block the sensor 29. The sensor 29 transmits an electrical signal to the controller 13, so that the controller 13 controls the push rod motor 18 to start. The output end of the push rod motor 18 moves downward to drive the moving frame 14 to move downward. The output end of the sensor 29 is electrically connected to the input end of the controller 13. The output end of the controller 13 is electrically connected to the input end of the push rod motor 18.

[0033] It should be noted that all the electrical equipment mentioned above requires an external power source, and the drive motor 15 can be started and stopped via an external switch.

[0034] In this embodiment, as Figure 2 As shown, a fixed shaft 22 is slidably connected inside the connecting shaft 12. An auxiliary block is installed at the outer end of the fixed shaft 22. The auxiliary block is slidably connected inside the connecting shaft 12. A connecting pin 23 passes through the outer surface of the connecting shaft 12. One end of the connecting pin 23 that passes through the connecting shaft 12 is threaded through the auxiliary block. A contact pad 24 is installed on the outer surface of the fixed shaft 22. The contact pad 24 is a soft pad with a certain elasticity. After the small roll is wrapped around the outer surface of the contact pad 24, the contact pad 24 can fill the interior of the small roll. A connecting piece 25 is slidably connected inside the contact pad 24. A plug pin 26 passes through the outer side of the connecting piece 25. One end of the plug pin 26 that passes through the connecting piece 25 is threaded through the fixed shaft 22. A support block 27 is installed on the outer side of the connecting piece 25. A second contact plate 28 is installed on the outer side of the support block 27.

[0035] Working principle: The connecting piece 25 is slid into the contact pad 24, the insert pin 26 is inserted into the fixed shaft 22 through the connecting piece 25, and then the insert pin 26 is tightened clockwise to fix the connecting piece 25, so that the second contact plate 28 enters the contact pad 24. The auxiliary block is slid into the connecting shaft 12, the connecting pin 23 is inserted into the auxiliary block through the connecting shaft 12, and then the connecting pin 23 is tightened clockwise to fix the fixed shaft 22. The small roll is placed on the outer surface of the contact pad 24 so that the contact pad 24 fills the inside of the small roll, and the second contact plate 28 contacts the small roll.

[0036] Loosen the fixing pin 5 counterclockwise, and move the blocking block 4 upward along the outer surface of the buffer rod 8 and the inside of the connecting frame 3. The upward movement of the blocking block 4 causes the sensor 29 to move upward. After the movement is complete, tighten the fixing pin 5 clockwise to fix the blocking block 4. Wrap one end of the tape on the surface of the large roll around the surface of the small roll (the first contact plate 10 is in contact with the wrapped tape).

[0037] Start the drive motor 15 (the drive motor 15 on the front side rotates in reverse, and the drive motor 15 on the rear side rotates in the forward direction). The output end of the drive motor 15 rotates, which drives the first drive gear 16 to rotate. The first drive gear 16 rotates, which drives the second drive gear 17 to rotate. The second drive gear 17 rotates, which drives the connecting shaft 12 to rotate. The connecting shaft 12 rotates, which drives the fixed shaft 22 to rotate, and the small roll is rewound.

[0038] As the diameter of the tape rewinding gradually increases, the first contact plate 10 also moves upward with the tape. The upward movement of the first contact plate 10 drives the blocking plate 11 to move upward. The upward movement of the first contact plate 10 drives the moving block 6 to move upward. The moving block 6 moves upward along the connecting frame 3. The upward movement of the moving block 6 drives the buffer spring 7 to move upward. The upward movement of the moving block 6 drives the buffer rod 8 to move upward. The upward movement of the buffer spring 7 drives the buffer sheet 9 to move upward, so that the buffer sheet 9 contacts the blocking block 4 and gradually compresses the buffer spring 7.

[0039] When the baffle plate 11 moves upward to block the sensor 29, the sensor 29 transmits an electrical signal to the controller 13. The controller 13 controls the push rod motor 18 to start. The output end of the push rod motor 18 moves downward, driving the moving frame 14 to move downward. The moving frame 14 moves downward along the inside of the mounting plate 2. The downward movement of the moving frame 14 drives the transmission motor 15 to move downward. The downward movement of the transmission motor 15 drives the first transmission gear 16 to move downward. The downward movement of the first transmission gear 16 disengages from the second transmission gear 17, causing the second transmission gear 17 to stop rotating (at the same time, the controller 13 controls the transmission motor 15 to turn off). The downward movement of the moving frame 14 drives the moving rod 21 to move downward. The downward movement of the moving rod 21 compresses the fixing spring 20, buffering the moving frame 14, so that the fixing shaft 22 stops rewinding the tape.

[0040] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
