[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 4 , a torsion mechanism that can protect cards, a Möbius ring structure 11 is installed on one side of the support frame 2, the Möbius ring structure 11 includes a redirecting wheel 4 and a belt tensioning wheel 13 that are symmetrically arranged on the left and right to maintain a first axial center spacing, two reversing shafts 6 that are symmetrically arranged on the left and right to maintain a second axial center spacing, and two belt auxiliary pressure wheels 15 that are symmetrically arranged on the left and right to maintain a third axial center spacing. The torsion belt 3 is sequentially wrapped around the redirecting wheel 4 and the belt tensioning wheel 13, twisted 180° around the reversing shaft 6 arranged below the redirecting wheel 4, and the reversing shaft 6 below the belt tensioning wheel 13, twisted 180° around the redirecting wheel 4 to form a rotating closed loop, the two belt auxiliary pressure wheels 15 are respectively arranged above the two reversing shafts 6 and abut against the torsion belts 3 to form a gap opening on the upper and lower torsion belts 3, the two gap openings and the parallel torsion belts 3 form a flipping channel that rotates 180 degrees head to tail; wherein, the second axial center spacing is equal to the third axial center spacing and is smaller than the first axial center spacing.

[0022] Specifically, the redirecting wheel 14 and the belt tensioning wheel 13 are symmetrically arranged at the two ends of the Möbius ring structure, and the two belt auxiliary pressure wheels 15 are symmetrically arranged between the redirecting wheel 14 and the belt tensioning wheel 13. Two reversing shafts 6 are arranged perpendicular to the axis directly below the two belt auxiliary pressure wheels 15. The axial center spacing of the two belt auxiliary pressure wheels 15 is equal to the axial center spacing of the two reversing shafts 6 and is smaller than the axial center spacing of the redirecting wheel 14 and the belt tensioning wheel 13; the twisting belt 3 is first wrapped around and sleeved between the redirecting wheel 14 and the belt tensioning wheel 13, and then the twisting belt 3 is twisted 180° around the reversing shaft 6 and the belt tensioning wheel sleeved below the redirecting wheel 14 Between the reversing shafts 6 below the wheel 13, the torsion belt 3 between the reversing wheel 14 and the bottom of the belt tensioning wheel 13 and the top of the two reversing shafts 6 is twisted 180° to form a Möbius ring mechanism. The two belt auxiliary pressure wheels 15 are respectively arranged above the two reversing shafts 6 and rest on the torsion belt 3 to control the size of the gap opening formed between the upper and lower torsion belts 3 to ensure that the gap opening matches the thickness of the card so that the card has enough force to complete the 180° flip in the torsion belt 3 without falling. The two gap openings and the parallel torsion belts 3 together form a flip channel for the card to pass through, which rotates 180° head to tail.

[0023] As a technical optimization solution of the utility model, it also includes a guide rubber wheel 8 located in the middle position to press outward or inward to adjust the gap of the flip channel, and a longitudinal stretching idler wheel 9 located in the middle position to stretch the torsion belt 3 upward or downward.

[0024] Specifically, the guide rubber wheel 8 is used to control the clamping force of the torsion belt 3 on the card during the flipping process. The guide rubber wheel 8 can rotate flexibly at multiple angles. When the card passes through the torsion belt 3, the guide rubber wheel 8 presses against the torsion belt 3 to maintain pressure, and always keeps the gap of the torsion belt 3 less than or equal to the thickness of the card during the flipping process, so that the card will not fall off; the two longitudinal stretching idler wheels 9 arranged directly above and below the guide rubber wheel 8 press against the torsion belt 3 mounted on the redirecting wheel 4 and the belt tensioning wheel 13 and the torsion belt 3 mounted on the reversing shaft 6 respectively, and the longitudinal stretching idler wheels 9 directly above and below the guide rubber wheel 8 press against the torsion belt 3 upward and downward to stretch the belt, thereby increasing the tension of the torsion belt 3, keeping the speed of the torsion belt 3 the same, and preventing the card from being scratched.

[0025] As a technical optimization solution of the present invention, a mounting frame 12 is connected to the center of the bottom of the support frame 2, a power motor 10 is installed inside the mounting frame 12, and one end of the support frame 2 and the output end of the power motor 10 are commonly connected to a transmission mechanism 20.

[0026] Specifically, the support frame 2 is used to fix and support the entire device. The mounting frame 12 is connected at the center of the bottom of the support frame 2. The mounting frame 12 is mainly used to install the power motor 10 and provide it with stable support. The power motor 10 is installed inside the mounting frame 12. The power motor 10 provides a power source for the transmission mechanism, thereby driving the operation of the entire device.

[0027] As a technical optimization solution of the present invention, one end of the support frame 2 is connected to a protective cover 1, and one end of the mounting frame 12 is connected to a protective cover 2 14. The transmission mechanism 20 includes a driving disc 17, two output shafts 5 and several belt angle idler pulleys 19. The transmission mechanism 20 also includes a redirecting wheel 4 and a reversing shaft 6. One end of the two output shafts 5 passes through the support frame 2, and the redirecting wheel 4 and the reversing shaft 6 also pass through the support frame 2. The outside of the output shaft 5, the reversing shaft 6, the driving disc 17 and the belt angle idler pulley 19 are jointly sleeved with a rotating belt 18, and the two output shafts 5 are respectively located on both sides of the support frame 2.

[0028] Specifically, one end of the support frame 2 and the mounting frame 12 is connected with a protective cover 1 and a protective cover 2 14 to reduce external interference with the transmission mechanism. One end of the two output shafts 5 of the transmission mechanism passes through the support frame 2, so that the output shaft 5 can extend out of both sides of the support frame 2, and the redirecting wheel 14 and the reversing shaft 6 also pass through the support frame 2. The driving disk 17, the two output shafts 5, the reversing shaft 6 and the external part of several belt angle idler wheels 19 are collectively sleeved with a rotating belt 18, so that the output end of the power motor 10 transmits power through the driving disk 17, and the driving disk 17 transmits power through the belt angle. The idler wheel 19 changes the direction of the rotating belt 18 to transmit power to the output shaft 5. The output shaft 5 transmits power to the reversing shaft 6 through the rotating belt 18, so that the rotating belt 18 and each idler wheel assembly can realize power conversion and transmission. The two output shafts 5 are respectively located on both sides of the support frame 2, so that the power of the two output shafts 5 is transmitted to the Möbius ring structure on the other side of the support frame, thereby driving the operation of the entire device. By penetrating the support frame 2 to transmit power to the other end, it can not only improve the transmission efficiency, but also ensure the stability and reliability of the device.

[0029] When the utility model is in use, the card is transported to the torsion belt 3 by the belt of the upstream device. The torsion belt 3 forms a slit opening under the pressure of the reversing shaft 6 and the belt auxiliary pressure wheel 15. The card enters the torsion belt 3 through the slit opening. The torsion belt 3 is Figure 1The middle guide rubber wheel 8 rotates exactly 90°, and the belt auxiliary pressure wheel 15 at the belt tensioner 13 stops twisting, thus forming a Möbius loop-shaped gap that rotates 180° from end to end. There is no speed difference between the belts above and below the gap. After passing through the gap, the card naturally flips 180° without sliding relative to each other and causing damage. The card enters the gap at one end of the redirecting roller 4 and twists 180° before exiting the gap at the other end of the belt tensioner 13. After breaking free from the twisting belt 3, the card enters the belt of the downstream device. Furthermore, negative pressure holes are provided on both the upstream and downstream belts. During the card transmission process, no external negative pressure adsorption mechanism is actively used. The Bernoulli principle is used during high-speed card transmission, so the card will not fly out during high-speed operation. At the same time, an axial misalignment mechanism is used when the card enters and exits the flipping mechanism, that is, the belts are alternated, ensuring that the card is always within the belt range and does not lose control. The torsional belt 3 is a flexible belt with a set distance of approximately 0.3mm and a compression amount of 1mm, which can pass through a card of 0.3-1.3mm. During the operation of the flip mechanism, the external cooling fan and external dust removal equipment are turned on, and at the same time, the linear motor 166 moves back and forth outside the moving rod 165. Through the cooperation of the flexible cooling air inlet pipe 161 and the cooling air hole 1610, external cold air blows onto the torsional belt 3, cooling the torsional belt 3; the linear motor 166 moves back and forth, driving the two protective covers 162 to move back and forth, and the cleaning brush 168 is used to clean the torsional belt 3. The generated dust is absorbed by the dust suction hole 169 and discharged through the dust suction pipe 163, improving the cleanliness of the surface of the torsional belt 3.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
