[0038] Example: As attached Figure 1 As shown, the fully automatic film taking device for post-needle patch comprises a shell 1, a post-needle patch taking port 2 is provided on the shell 1, a post-needle patch placing device 3 is provided in the shell 1, the post-needle patch placing device 3 is located at one side of the post-needle patch taking port 2, a waste tape recovery device 4 is also provided in the shell 1, the waste tape recovery device 4 is located below the post-needle patch taking port 2, a photoelectric sensor 5 is provided on the upper side of the post-needle patch taking port 2, and a PCB control board 6 electrically connected to the photoelectric sensor 5 is also provided in the shell 1.

[0039] The shell 1 includes a first shell plate 11 arranged horizontally, a second shell plate 12 and a third shell plate 13 vertically connected to the two narrow ends of the first shell plate 11, the height of the second shell plate 12 is higher than the height of the third shell plate 13, the free ends of the second shell plate 12 and the third shell plate 13 are connected to a fourth shell plate 14, and the connection between the fourth shell plate 14 and the second shell plate 12 and the third shell plate 13 is arc-shaped, and the shell 1 also includes a fifth shell plate 15 and a sixth shell plate (the sixth shell plate has the same structure as the fifth shell plate 15 and is not shown in the figure) that seal the first shell plate 11, the second shell plate 12, the third shell plate 13 and the fourth shell plate 14; this structure makes the space formed large on one side and small on the other side, the large space part is used to place the needle post-sticking roll, and the small space part is used to place the recycled waste tape.

[0040] The needle back patch taking port 2 is arranged on the fourth housing plate 14 , and a needle back patch guide column 7 is also arranged on the fourth housing plate 14 . The needle back patch guide column 7 is located in the needle back patch taking port 2 .

[0041] The needle back patch placement device 3 includes a central roller 31 arranged on the fifth shell plate 15, and the fifth shell plate 15 is also provided with a circular needle back patch positioning shell 32 with the central roller 31 as the center of the circle, and the needle back patch positioning shell 32 is used to locate the position of the needle back patch roll so that the needle back patch roll and the needle back patch access port 2 are located in the same direction; a needle back patch turntable 33 is rotatably provided on the central roller 31, and the diameter of the needle back patch turntable 33 is larger than the diameter of the needle back patch positioning shell 32; such a configuration can prevent the needle back patch positioning shell 32 from hindering the rotation of the needle back patch roll.

[0042] The waste belt recovery device 4 includes a driving gear 41, a small gear 42 and a large gear 43 arranged on the fifth shell plate 15, and the driving gear 41 is connected to the power of the motor 44; the driving gear 41 is meshed with the small gear 42 and the large gear 43, the centers of the small gear 42 and the large gear 43 are on the same horizontal line, and the diameter of the large gear 43 is larger than that of the small gear 42; a recovery guide shaft 45 is extended from the small gear 42, a bearing 421 is provided between the small gear 42 and the recovery guide shaft 45, and a pressure plate device 47 is provided at the extended end of the recovery guide shaft 45; a waste belt recovery wheel 48 is meshed on the large gear 43.

[0043] The large gear 43 includes a gear body 431 sleeved on the gear shaft 49, a gear seat 432 is provided on the gear body 431, and a connecting protrusion 433 is provided at the free end of the gear seat 432; the waste belt recovery wheel 48 includes a recovery wheel body 481 sleeved on the gear shaft 49, and a waste recovery shaft 482 is extended from the recovery wheel body 481, and a connecting groove 483 matching the connecting protrusion 433 is provided on the side of the recovery wheel body 481 opposite to the gear seat 432, and a spring 484 is provided at the end of the waste recovery shaft 482 away from the recovery wheel body 481. The recovery guide shaft 45 driven by the small gear 42 rotates continuously. When the waste belt on the waste belt recovery wheel 48 is tightened, the waste belt recovery wheel 48 can no longer rotate. At this time, the large gear 43 will disengage from the waste belt recovery wheel 48, that is, the protrusion 433 and the groove 483 disengage, and the large gear 43 rotates idly; if the waste belt is loose, the spring 484 will press the waste belt recovery wheel 48 back, and the waste belt recovery wheel 48 and the large gear 43 will mesh again, that is, the protrusion 433 and the groove 483 will be combined again, and the waste belt recovery wheel 48 will rotate with the large gear 43.

[0044] A gear cover plate 40 is provided between the recovery guide shaft 45 and the waste belt recovery wheel 48 and the driving gear 41, the small gear 42 and the large gear 43; the setting of the gear cover plate 40 can prevent the waste belt from being entangled on the driving gear 41, the small gear 42 and the large gear 43 when it is loose, thereby affecting its use.

[0045] The pressure plate device 47 includes a pressure plate shell 471, and the pressure plate shell 471 passes through the gear cover plate 40 and is connected to the fifth shell plate 15. The fifth shell plate 15 is provided with a mounting seat 151. One end of the pressure plate shell 471 extends through the gear cover plate 40 and is axially connected to the mounting seat 151. A pressure plate 472 is provided at the free end of the pressure plate shell 471. A reset spring 473 is provided between the pressure plate 472 and the pressure plate shell 471. The pressure plate 472 is arranged in contact with the recovery guide shaft 45; the setting of the reset spring 473 can allow the waste belt to better contact with the recovery guide shaft 45, so that the recovery guide shaft 45 drives the waste belt to move.

[0046] A recovery guide shaft bracket 46 is provided between the recovery guide shaft 45 and the fifth shell plate 15, one end of the recovery guide shaft bracket 46 is connected to the fifth shell plate 15, and the other end of the recovery guide shaft bracket 46 is connected to the free end of the recovery guide shaft 45; because the recovery guide shaft 45 is subjected to the force of the pressure plate device 47 for a long time, it is easy to cause the recovery guide shaft 45 to tilt. In order to solve this problem, a recovery guide shaft bracket 46 is provided to extend its service life.

[0047] The working principle of the present invention is:

[0048] When in use, first place the needle-rear sticker roll on the needle-rear sticker turntable 33, pull one end of the needle-rear sticker roll out from the position below the needle-rear sticker roll, pass through the needle-rear sticker guide column 7 from above the needle-rear sticker taking port 2 to below the needle-rear sticker taking port 2, peel off the needle-rear sticker from the waste tape, pass the waste tape between the recovery guide shaft and the pressure plate device 47, and wrap it around the waste tape recovery wheel 48 to recover the waste tape.

[0049] When the photoelectric sensor 5 senses a human hand approaching, the signal is processed by the PCB control board 6 to drive the motor 44 to start, and the motor 44 drives the driving gear 41 to rotate. The driving gear 41 also drives the small gear 42 and the large gear 43 to rotate. The rotation of the small gear 42 drives the recovery guide shaft to rotate. The waste belt moves forward under the pulling force of the recovery guide shaft and the pressure plate device 47. The rotation of the large gear 43 drives the waste belt recovery wheel 48 to rotate, and the waste belt is wound around the waste belt recovery wheel 48.

[0050] During this process, because the recovery guide shaft driven by the small gear 42 is continuously rotating, when the waste belt on the waste belt recovery wheel 48 is tightened, the waste belt recovery wheel 48 can no longer rotate. At this time, the large gear 43 will be separated from the waste belt recovery wheel 48 and the large gear 43 will idle. If the waste belt is loose, the spring will press the waste belt recovery wheel 48 back, and the waste belt recovery wheel 48 and the large gear 43 will mesh again, and the waste belt recovery wheel 48 will rotate with the large gear 43.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
