When the material belt is conveyed in the feed card seat 4, in order to avoid the material belt from tilting and reduce the friction between the material belt and the feed card seat 4, the transverse push rod 25 is started and the limit card plate 26 is driven to move in cooperation with the transverse guide rod 24, so as to adjust the distance between the two groups of limit card plates 26, so that the material belt passes between the two groups of limit card plates 26, and the two groups of limit card plates 26 play a limiting role on both sides of the material belt.

[0044] like Figure 5 As shown, a plurality of guide wheels 27 are movably mounted on the outer side surface of the limit card plate 26, and a groove is provided on the surface of the material rail 5 for cooperating with the limit card plate 26. The setting of the guide wheels 27 can reduce the friction between the limit card plate 26 and the material belt, making the movement of the material belt smoother.

[0045] like Figure 1 As shown, a first guide wheel 8, a second guide wheel 9 and a lifting guide wheel 3 are provided below the unwinding disk 7. The first guide wheel 8 is provided above the second guide wheel 9, and the lifting guide wheel 3 is movably installed below the second guide wheel 9. The arrangement of the first guide wheel 8, the second guide wheel 9 and the lifting guide wheel 3 can satisfy the bidirectional guiding operation of the material belt. When the material belt is transported to one side, as shown in FIG. Figure 7 As shown in A, after the material belt passes through the first guide wheel 8 and the second guide wheel 9, it is output from one side of the lifting guide wheel 3. When the material belt is transported to the other side, as shown in FIG. Figure 7 As shown in B, after passing through the first guide wheel 8 and the second guide wheel 9, the material belt is output from the other side of the lifting guide wheel 3.

One end of the material belt passes through the lower part of the driver 6. When the driver 6 is in use, the motor 19 drives the chain 18 so that the chain 18 drives the driving wheel 15 to rotate. When the driving wheel 15 contacts the material belt, the driving wheel 15 can be used to drive the material belt to move. By adjusting the height of the driver 6, the driver 6 can be suitable for material belt structures of different thicknesses, thereby improving its scope of application.

[0051] During use, when the material belt is conveyed in the material conveying base 4, in order to avoid the material belt from tilting and reduce the friction between the material belt and the material conveying base 4, the transverse push rod 25 is started, and the transverse guide rod 24 is cooperated to drive the limit card plate 26 to move, thereby adjusting the distance between the two sets of limit card plates 26, so that the material belt passes between the two sets of limit card plates 26, and the two sets of limit card plates 26 play a limiting role on both sides of the material belt, and can flexibly apply to material belt structures of different widths. Secondly, the lifting card sleeve 14 has a lifting adjustment structure, which can adjust the use height of the driving wheel 15. The user pulls the lifting card sleeve 14 up and down, so that the lifting card sleeve 14 drives the driving wheel 15 to move up and down, and adjusts the installation height of the driving wheel 15, so that the driving wheel 15 can contact with material belts of different thicknesses, thereby meeting the conveying operation of material belts of different thicknesses;

[0052] By providing the lifting guide wheel 3 and the limiting ring 30, when the material belt conveying foolproof device is used, it has a material guide limiting structure, which improves the stability of the material belt during the guiding and conveying operation and prevents the material belt from falling off;

[0053] During operation, the first guide wheel 8, the second guide wheel 9 and the lifting guide wheel 3 are first used to meet the bidirectional guiding operation of the material belt. When the material belt is transported to one side, such as Figure 7 As shown in A, after the material belt passes through the first guide wheel 8 and the second guide wheel 9, it is output from one side of the lifting guide wheel 3. When the material belt is transported to the other side, as shown in FIG. Figure 7 As shown in B, after passing through the first guide wheel 8 and the second guide wheel 9, the material belt is output from the other side of the lifting guide wheel 3, and the setting of the two sets of limit rings 30 can optimize the use of the first guide wheel 8, the second guide wheel 9 and the lifting guide wheel 3. The setting of the limit rings 30 makes the first guide wheel 8, the second guide wheel 9 and the lifting guide wheel 3 have auxiliary positioning structures to prevent the material belt from tilting on the surface of the first guide wheel 8, the second guide wheel 9 and the lifting guide wheel 3. The two sets of limit rings 30 are set to limit the two sides of the material belt respectively.
