[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. In the present invention, after the motor output shaft carries a winding rod to wind up the tape, the connecting plate is pulled outward to separate the motor from the winding rod, and then the winding rod is moved along the L-shaped slide. After the winding rod leaves the support frame, the tape is cut with a blade. At the same time, a new winding rod is pressed between the two supports, and then the tape with the adhesive surface facing up is smoothly bonded to the new winding rod. Then the connection between the motor and the new winding rod is repeated, which prevents the tape from shrinking and ensures continuous and high-speed winding of the tape.

[0015] 2. In the present invention, before the tape is wound, the tape is controlled to pass through the bottom of the cylinder and the material guide channel, and then the back of the tape moves along the surface of the cylinder and the surface of the guide arc plate. Then, when the tape reaches between the two supports, the adhesive surface of the tape faces upward smoothly, which helps to quickly bond the winding rod and the tape, further improving the efficiency of the rod change.

It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0027] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0028] The following describes an anti-retraction device for winding a polyimide tape provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0029] Example 1:

[0030] Combine Figure 1-5 As shown, the utility model provides an anti-retraction device for winding polyimide tape, comprising a rod-changing mechanism 100 and a winding mechanism 200. The rod-changing mechanism 100 comprises two supports 110, an L-shaped slide 120 provided inside the supports 110, a winding rod 130 slidably connected between the two L-shaped slides 120, and a blade 140 connected between the two supports 110.

[0031] The winding mechanism 200 includes two plate sleeves 210 connected to the support frame 110 near the front end of the blade 140, a connecting plate 220 slidably connected between the two plate sleeves 210, a tension spring 230 connected between the plate sleeves 210 and the connecting plate 220, and a motor 240 installed inside the connecting plate 220, and the output shaft of the motor 240 slides and extends to the inside of a winding rod 130.

[0032] Furthermore, a guiding mechanism 300 is provided between the two supports 110, and the guiding mechanism 300 includes a base plate 310 connected between the two supports 110, a cylinder 320 installed inside the base plate 310, and a guide arc plate 330. The guiding mechanism 300 can guide the walking path of the tape, ensure that the adhesive surface of the tape comes between the two supports 110, and enable the winding rod 130 to be connected to the tape.

[0033] Furthermore, the guide arc plate 330 is provided on one side of the cylinder 320 , and the cylinder 320 and the guide arc plate 330 are both made of plastic material, which reduces the difficulty of material selection when manufacturing the cylinder 320 and the guide arc plate 330 .

[0034] Furthermore, a U-shaped plate 400 is installed at the bottom of the guide arc plate 330, and a material guide channel is left between the guide arc plate 330 and the U-shaped plate 400. After the U-shaped plate 400 is set, the tape can perfectly fit the guide arc plate 330 and move after passing through the material guide channel.

[0035] Example 2:

[0036] Combine Figure 2-3 As shown, based on the first embodiment, a circular opening is provided on the support frame 110 near the front end of the blade 140, and the output shaft of the motor 240 is movable through the circular opening. The circular opening is provided to ensure that the output shaft of the motor 240 can be smoothly connected to the winding rod 130.

[0037] Example 3:

[0038] Combine Figure 4 As shown, in the above embodiment, the output shaft of the motor 240 is set to be rectangular. The shape of the output shaft of the motor 240 is designed so that the output shaft of the motor 240 can smoothly rotate with the winding rod 130 after being inserted into the winding rod 130.

[0039] The working principle and use process of the present invention: When the device is put into actual use, the movable end of the external tape is passed through the bottom of the cylinder 320, and then the back of the tape is attached to the surface of the cylinder 320 and the outer wall of the guide arc plate 330 is moved, and then the tape is brought between the two supports 110. At this time, the adhesive surface of the tape faces upward, and then the operator pulls the connecting plate 220 outward to make the output shaft of the motor 240 leave the circular opening, and then presses the reel rod 130 between the two L-shaped slides 120, and then releases the connecting plate 220, and then the tension spring 230 contracts, so that the output shaft of the motor 240 passes through the round mouth, and then is inserted into the winding rod 130, and then the motor 240 is started, and the winding rod 130 can complete the winding of the tape. Then, when changing the rod, the connecting plate 220 is pulled outward to separate the motor 240 from the above-mentioned winding rod 130, and then the winding rod 130 with the wound tape is moved along the L-shaped slide 120, and then the winding rod 130 is repeatedly pressed in, and then the above method is used to complete the continuous and high-speed winding of the tape.
