[0027] The knob 12 and the connecting rod 11 are fixedly arranged, and the connecting rod 11 and the knob 12 are fixedly arranged, the tooth plate 9 and the gear 10 are rotatably connected, the fixed plate 13 and the tidying plate 16 are tightly fitted, and the slide groove 14 and the slider 15 are slidably connected. When the device starts working, the staff puts the cloth to be processed into the die inlet 3, and then the processed mold comes out of the die outlet 4 and is transmitted to the left. Before the device starts working, the staff can drive the connecting rod 1 by turning the knob 12 on the second support rod 102, which is an electric knob design. 1, the rotation of the connecting rod 11 can drive the gears 10 on both sides to rotate on the toothed plate 9, and the fixed plate 13 is connected to the top of the gear 10, so the distance between the upper and lower fixed plates 13 can be adjusted, and the distance between the upper and lower tidying plates 16 can be adjusted to a suitable position to adapt to the tidying of molds of different thicknesses.

[0028] The fixed latch 22 forms a latch structure through the circular hole 21 and the fixed hole 23. The first movable frame 20 and the second movable frame 17 are integrated. The mold-collecting roller 19 and the clamp 18 are clamped. Since the two sides of the mold-collecting roller 19 are connected with motors, the mold will be rolled up by the mold-collecting roller 19. After the single mold is rolled up, the staff can take out the mold-collecting roller 19 from the clamp 18, and then the staff can take out the fixed latch 22, and then rotate the first movable frame 20 to roll the next circular mold. After the hole 21 is aligned with the fixing hole 23 inside the third support rod 103, the fixing pin 22 is inserted into the circular hole 21 and the fixing hole 23 in sequence.

Therefore, the next mold-collecting roller 19 after rotation can be put into use, which is convenient for the next material collection work and the replacement of the mold-collecting roller 19.

[0029] Embodiment 2

[0030] See also Figure 1 and Figure 6 As shown, a mold changing device of an automobile door panel hemming machine, a heat dissipation strip 5 is installed on the right surface of the hemming machine 2, screw holes 6 are reserved at the four right corners of the hemming machine 2, fixing screws 7 are arranged inside the screw holes 6, and a partition plate 8 is installed on the right side of the heat dissipation strip 5.

[0031] The fixing screw 7 and the screw hole 6 are threadedly connected, the partition 8 and the heat dissipation strip 5 are tightly fitted, and the heat dissipation strip 5 and the edge wrapping machine 2 are welded. The edge wrapping machine 2 is located on the support frame 1, and the first support rod 101 plays a supporting role. When the device starts working, multiple heat dissipation strips 5 can have a heat dissipation effect on the device. The multiple screw holes 6 reserved behind the edge wrapping machine 2 are convenient for the staff to unscrew the fixing screws 7 to remove the partition 8 and regularly tidy up the heat dissipation strips 5.

[0032] Working principle: First, the hemming machine 2 is located on the support frame 1, and the first support rod 101 plays a supporting role. When the device starts working, multiple heat dissipation strips 5 can have a heat dissipation effect on the device. Multiple screw holes 6 reserved behind the hemming machine 2 are convenient for the staff to unscrew the fixing screws 7 to remove the partition 8, and regularly tidy up the heat dissipation strips 5. When the device starts working, the staff puts the cloth to be processed into the die inlet 3, and then the processed mold will come out of the die outlet 4 and be transmitted to the left. Before the device starts working, the staff can turn the knob 12 on the second support rod 102. The knob 12 is an electric knob design. To drive the rotation of the connecting rod 11, the rotation of the connecting rod 11 can drive the gears 10 on both sides to rotate on the toothed plate 9, and the upper part of the gear 10 is connected with a fixed plate 13, so the distance between the upper and lower fixed plates 13 can be adjusted, and the distance between the upper and lower tidying plates 16 can be adjusted to a suitable position to adapt to the tidying of molds of different thicknesses. Since there may be dust and fine hair on the molds just produced, the design of the tidying plate 16 is very necessary. After the device is finished working, the staff can also slide the slider 15 to remove and replace the tidying plate 16, and the slide groove 14 plays a role in assisting the sliding out;

[0033] Secondly, when the neatly arranged mold is conveyed to the left, since motors are connected to both sides of the mold collecting roller 19, the mold will be rolled up by the mold collecting roller 19. After a single mold is rolled up, the staff can take out the mold collecting roller 19 from the clamp 18. Subsequently, the staff can take out the fixing pin 22, rotate the first movable frame 20, align the next circular hole 21 with the fixing hole 23 inside the third support rod 103, and then insert the fixing pin 22 into the circular hole 21 and the fixing hole 23 in turn. At this time, the first movable frame 20 is still in a horizontal state. Since the first movable frame 20 and the second movable frame 17 are integrated, the second movable frame 17 and the first movable frame 20 will rotate at the same time and maintain the same state. Therefore, the next mold collecting roller 19 after rotation can be put into use, which is convenient for the next material collection work and the replacement of the mold collecting roller 19.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
