[0029] See Figures 1 to 7 As shown, a wire winding and unwinding device for preventing tangling includes a winding wheel 3, a pressing wheel 5, and a support member. A steel wire 4 is wound around the outer circumference of the winding wheel 3. The winding wheel 3 and the pressing wheel 5 are arranged side by side. The steel wire 4 is pressed between the winding wheel 3 and the pressing wheel 5. The winding wheel 3 and the pressing wheel 5 are arranged on the support member in opposite directions and are mutually driven and cooperated.

[0030] The winding wheel 3 is in transmission connection with a driving mechanism, which is an electric control driving mechanism; the support member is a shell.

[0031] The electric control driving mechanism comprises a motor 2 and a gear transmission pair 21 (a worm gear output in this embodiment), the input end of the gear transmission pair 21 is in transmission connection with the motor shaft of the motor 2, and the output end of the gear transmission pair 21 is in transmission with the winding wheel 3 through meshing of tooth surfaces. The output end is a driving gear 22, and the winding wheel 3 is provided with a driven gear 31, which is in transmission with the driving gear 22.

[0032] The winding wheel 3 and the pressing wheel 5 are respectively provided with a first tooth surface 32 and a second tooth surface 51, and the first tooth surface 32 and the second tooth surface 51 are in meshing.

[0033] The motor 2 is horizontally arranged in the shell, two winding wheels 3 are arranged in the shell, and the two ends of the motor shaft are respectively in transmission connection with the two winding wheels 3 through the gear transmission pair 21. The driven gear 31 and the first tooth surface 32 are respectively located at the two ends of the winding wheel 3.

[0034] The steel wire 4 is provided with a fixed part 41 and a free end 42, the fixed part 41 is in fixed connection with the winding wheel 3, the free end 42 extends out of the support member, and the steel wire 4 between the fixed part 41 and the free end 42 is tightly wound around the outer periphery of the winding wheel 3. The surface of the winding wheel 3 is provided with a clamping groove 34, the fixed part 41 of the steel wire 4 is the other end thereof and is connected with a fixing head (not shown in the figure, which is a prior art), and then the fixing head is embedded in the clamping groove 34 to realize fixation with the winding wheel 3.

[0035] The outer periphery of the winding wheel 3 is provided with a spiral groove 33, and the steel wire 4 is wound in the spiral groove 33, the wire diameter of the steel wire 4 is greater than the groove depth of the spiral groove 33, the pressing wheel 5 abuts against the surface of the steel wire 4 outside the winding wheel 3 (see C shown in Figure 7 ) and is separated from the outer surface of the spiral groove 33 by a certain distance (see D shown in Figure 7 ).

[0036] The center of the wire pressing wheel 5 is provided with a rotating shaft 52, the shell includes a front shell 12 and a rear shell 11, the rear shell 11 is provided with a fixed shaft seat 15 corresponding to one end of the rotating shaft 52, the rear shell 11 is provided with a stand 16 corresponding to the side of the fixed shaft seat 15, the stand 16 is provided with a pressing cover 17, the pressing cover 17 is provided with a movable shaft seat 18 corresponding to the other end of the rotating shaft 52, the fixed shaft seat 15 and the movable shaft seat 18 are respectively provided with shaft holes corresponding to the end of the rotating shaft 52, the rotating shaft 52 is inserted into the shaft hole, and a soft sleeve 53 is arranged between the rotating shaft 52 and the inner wall of the shaft hole. The soft sleeve 53 is a silica gel sleeve which wraps the outer periphery and end face of the end of the rotating shaft 52. The wire pressing wheel 5 is only supported on one of the shells (only provided on the rear shell 11 in this embodiment), thereby reducing the problem that the rotating shaft 52 is not parallel to the winding wheel 3 due to assembly errors. In addition, since the shell and the wire pressing wheel 5, the winding wheel 3 and the like are mainly processed by plastic, the assembly precision and the material deformation amount can be accurately controlled, but the wire pressing wheel 5 is pressed against the surface of the steel wire 4 outside the winding wheel 3 and is separated from the outer surface of the spiral groove 33 by a certain distance, and this adjustment is very critical, therefore, a gap (for example, the relationship between Φ4 and Φ3) is reserved in the cooperation of the shaft hole and the rotating shaft, and the gap is compensated by the soft sleeve 53.

[0037] In combination Figure 8 As shown in the figure, a soft leather 54 can also be arranged on the outer periphery of the wire pressing wheel 5 to eliminate the gap between the wire pressing wheel and the steel wire caused by the tolerance due to assembly or material deformation.

[0039] The working principle is that the wire pressing wheel 5 is pressed against the surface of the steel wire 4 outside the winding wheel 3 and is separated from the outer surface of the spiral groove 33 by a certain distance, when the winding wheel 3 rotates, the wire pressing wheel 5 and the winding wheel 3 move synchronously in opposite directions, the wire pressing wheel 5 and the winding wheel 3 drive the steel wire 4 to be unwound or wound like a set of extrusion wheels, since the steel wire 4 is synchronous with the winding wheel 3, the steel wire 4 and the winding wheel 3 always maintain the original tight state, avoiding the winding phenomenon caused by relaxation. In addition, since the winding wheel 3 and the wire pressing wheel 5 are directly transmitted by the tooth surface meshing, the transmission is reliable and does not slip, which ensures the synchronism of the steel wire 4 and the winding wheel 3, even if the steel wire does not have enough load or meets resistance, it will not cause the steel wire 4 and the winding wheel 3 to relax, jump and appear the problem of winding.
