[0045] Referring to Figure 3 and Figure 4The feeding assembly 4 comprises a rotating roller 41 and an expansion sleeve 42, the expansion sleeve 42 is fixedly connected to the outer circumferential surface of the rotating roller 41, and the stainless steel belt is wound on the expansion sleeve 42. When the stainless steel belt is conveyed outward, the rotating roller 41 is driven to rotate by the friction between the stainless steel belt and the expansion sleeve 42.

[0046] With reference to Figure 3 and Figure 5 The extrusion assembly 5 is provided with two, one extrusion assembly 5 is located at one end of the rotating roller 41 along the length direction, and the other extrusion assembly 5 is located at the other end of the rotating roller 41 along the length direction.

The end face of the adjusting plate 543 towards the operation block is fixedly connected with a driving block 5431, and the driving block 5431 can pass through the operation hole 5412. The driving block 5431 is used for moving the adjusting plate 543 away from the tension spring 542 by the worker.

[0048] With reference to Figure 5 and Figure 6 The plurality of tension springs 542 are fixedly connected to the bottom wall of the adjusting groove 5411, the plurality of tension springs 542 are arrayed along the length direction of the adjusting block 541, and the end face of the tension spring 542 away from the bottom wall of the adjusting groove 5411 is fixedly connected with the adjusting plate 543. The plurality of fixed rods 52 can pass through the adjusting groove 5411, the plurality of fixed rods 52 are arrayed along the length direction of the adjusting block 541, and the end face of the plurality of fixed rods 52 is fixedly connected with the end face of the adjusting plate 543 towards the expansion sleeve 42. The pressing rod 53 is used for extruding the stainless steel belt, and the plurality of pressing rods 53 are respectively sleeved on the outer circumferential surface of the corresponding fixed rod 52. The outer circumferential surface of the fixed rod 52 is threadedly connected with a fixed ring 521.

[0049] With reference to Figure 2 and Figure 6When the pressing rod 53 is attached to the expansion sleeve 42, the tension spring 542 is in a stretched state. When the stainless steel belt is transported to the flattening device 3, the tension spring 542 drives the adjusting plate 543 to move, so that the pressing rod 53 always presses the stainless steel belt until the stainless steel belt is separated from the expansion sleeve 42.

[0050] With reference to Figure 5 and Figure 7 , the fixed strip 23 is fixedly connected to the support frame 1, and the fixed plate 2 is integrally formed on the end face of the fixed strip 23 away from the support frame 1. The fixed hole 21 is formed in the fixed plate 2, and the cross section of the fixed hole 21 is a square.

[0051] With reference to Figure 3 and Figure 7 , the first gear 43 is fixedly connected to the outer circumferential surface of the rotating roller 41, the fixed groove 44 is formed in the end face of the first gear 43 facing the fixed plate 2, the cross section of the fixed groove 44 is a square, and the fixed hole 21 is aligned with the fixed groove 44. The second magnet 441 is fixedly connected to the bottom wall of the fixed groove 44, the iron rod 22 is arranged in the fixed groove 44, the iron rod 22 is a cuboid, and the iron rod 22 can be located in the fixed hole 21 and the fixed groove 44 at the same time.

[0052] With reference to Figure 5 and Figure 7 , the first magnet 51 is fixedly connected to the outer surface of the fixed rod 52 facing the expansion sleeve 42, and the magnetic force of the first magnet 51 is greater than that of the second magnet 441. When the fixed rod 52 moves towards the expansion sleeve 42, and the first magnet 51 is in the same horizontal position as the iron rod 22, the first magnet 51 can attract the iron rod 22 out of the fixed groove 44 to release the rotation constraint of the rotating roller 41.

[0053] With reference to Figure 5 and Figure 7 , when the stainless steel belt is wound on the expansion sleeve 42 for several turns, the first magnet 51 is not in the same plane as the fixed hole 21 and the fixed groove 44, and the iron rod 22 is located in the fixed hole 21 and the fixed groove 44, so that the first gear 43 is in a locked state; when the stainless steel belt is wound on the expansion sleeve 42 for the last two turns, the first magnet 51 is in the same plane as the fixed hole 21 and the fixed groove 44, so that the first magnet 51 attracts the iron rod 22 out of the fixed groove 44, thereby allowing the first gear 43 to be in an unlocked state. When the first gear 43 is in a locked state, the rotating roller 41 only rotates without driving the first gear 43 to rotate.

[0054] With reference to Figure 4 and Figure 5The support frame 1 is provided with a synchronous assembly 6, which is used for moving the two ends of the rotating roller 41 towards the flattening device 3 at the same time when the first gear 43 is in the unlocked state. The synchronous assembly 6 comprises a second gear rack 62 and a second gear 61. The end surface of the support frame 1 is fixedly connected with two support plates 12, one of which is integrally formed with the first gear rack 11 on the end surface facing the rotating roller 41, and the second gear rack 62 is integrally formed on the end surface of the other support plate 12 facing the rotating roller 41.

[0055] With reference to Figure 2 and Figure 3 , the first gear rack 11 and the second gear rack 62 both extend towards the flattening device 3.

[0056] With reference to Figure 3 and Figure 4 , the second gear 61 is fixedly connected to the outer circumferential surface of the rotating roller 41, and the first gear 43 and the second gear 61 are located on the opposite end surfaces of the rotating roller 41, respectively. The diameters of the first gear 43 and the second gear 61 are both smaller than the diameter of the expansion sleeve 42, the first gear 43 is engaged with the first gear rack 11, and the second gear 61 is engaged with the second gear rack 62.

[0057] With reference to Figure 2 and Figure 3 , when the first gear 43 is in the unlocked state, the rotating roller 41 rotates, and when the first gear 43 and the second gear 61 rotate, the first gear 43 and the second gear 61 move on the first gear rack 11 and the second gear rack 62, respectively, towards the flattening device 3. When the stainless steel belt is separated from the expansion sleeve 42, the expansion sleeve 42 is attached to the end surface of the flattening device 3, so that the distance between the stainless steel belt and the flattening device 3 is not enough to cause deformation and bending.

[0058] With reference to Figure 4 and Figure 5 , the end surface of the rotating roller 41 facing the second gear 61 is provided with a clamping groove 45, and the cross section of the clamping groove 45 is hexagonal. The end surface of the support frame 1 facing the second gear 61 is provided with an operation channel 13, which extends along the length direction of the second gear rack 62, and the operation channel 13 penetrates to the end surface of the support frame 1 away from the second gear rack 62. The clamping groove 45 is provided with a handle 46, which can move in the operation channel 13. When the handle 46 is embedded in the clamping groove 45, the handle 46 and the clamping groove 45 are fixed to each other, that is, when the handle 46 is rotated, the rotating roller 41 can be rotated, the rotating roller 41 drives the expansion sleeve 42 to rotate and reset, and then the staff re-installs the iron rod 22 into the fixed groove 44 and the fixed hole 21.

[0059] The implementation principle of the embodiment 1 is that the adjusting block 541 moves to the bottom wall direction of the adjusting groove 5411 through the contraction of the tension spring 542, the adjusting block 541 drives the fixed rod 52 to move, so that the pressing rod 53 can always press the stainless steel belt, the stainless steel belt is always transported to the flattening device 3, until the first magnet 51 adsorbs the iron rod 22 from the fixed groove 44, so that the rotating roller 41 rotates, then the rotating roller 41 drives the first gear 43 and the second gear 61 to rotate, because the first gear 43 and the first rack 11 are meshed with each other and the second gear 61 and the second rack 62 are meshed with each other, the rotating roller 41 moves along the length direction of the first rack 11, until the stainless steel belt is separated from the rotating roller 41, at this time, the stainless steel belt cannot be bent because the distance between the rotating roller 41 and the flattening device 3 is too close, so that the stainless steel belt reduces the deviation phenomenon.

The end face of the third rack 5453 is fixedly connected with the fixed rod 52. When the motor 544 is started, the third gear 5441 drives the third rack 5453 to move in the vertical direction, so that the pressing rod 53 moves in the direction of the expansion sleeve 42.

[0063] The implementation principle of the embodiment 2 is that the motor 544 is started, the rotating shaft of the motor 544 drives the third gear 5441 to rotate, because the third gear 5441 and the third rack 5453 are meshed with each other, the third rack 5453 moves in the vertical direction, so that the fixed rod 52 moves in the direction of the expansion sleeve 42, and then the first magnet 51 can adsorb the iron rod 22.
