[0029] A buffer device for changing materials without stopping the machine, see Figure 1-Figure 4 : It includes an input guide roller 10, a buffer guide roller group 20, an output guide roller 30, a rear working station 40, and a vertical mounting plate 50;

[0030] The buffer guide roller group 20 includes two vertical guide rails 21, a group of sliding seats 22, and three groups of buffer guide rollers 23. The front end of the sliding seat 22 is convex with three groups of buffer guide rollers 23. The two vertical guide rails 21 are arranged at intervals. The rear surface of the sliding seat 22 is respectively embedded in the corresponding vertical guide rails 21 through each group of guide rail pairs 24 on both sides, which ensures that the lifting position of the sliding seat 22 is stable and reliable.

[0031] The top and bottom of the two vertical guide rails 21 are fixed to the corresponding positions of the front end surface of the vertical mounting plate 50 through the mounting frame 25;

[0032] The buffer guide roller group 20 is arranged between the input guide roller 10 and the output guide roller 30, and the rear work station 40 is arranged behind the output guide roller 30. The coil 60 changes direction along the input guide roller 10, changes direction through the three groups of buffer guide rollers 23, and then changes direction through the output guide roller 30 to enter the rear work station 40;

[0033] The coil 60 works normally to transport the coil under the tensioned state. The sliding seat 22 performs coil buffering and transportation when it is at the highest or lowest point. The sliding seat 22 gradually rises and falls until the coil 60 recovers the tensioned state. During the time when the sliding seat 22 rises and falls, the feeding part of the coil 60 is quickly replaced.

[0034] In specific implementation, when the coil 60 needs to be replaced, the external force drives the sliding seat 22 to move down to the bottom along the vertical guide rail 21, so that there is surplus coil in the coil. During the process of the coil 60 being transported backward, the surplus coil is transported to the rear working station 40, and the sliding seat 22 rises to maintain the tension state again. During this period of time, the feeding part of the coil is quickly replaced;

[0035] Or when the coil needs to be replaced, external force drives the sliding seat 22 to move up to the top along the vertical guide rail 21, so that there is surplus coil. During the process of the coil 60 being conveyed forward, the surplus coil is conveyed to the rear work station 40, and the sliding seat 22 descends to maintain the tensioned state again. During this period of time, the feeding part of the coil is quickly replaced.

[0036] In a specific embodiment, the three groups of buffer guide rollers 23 are identical guide rollers, which are arranged in parallel and spaced apart on the same horizontal straight line to ensure reliable guidance of the coil 60 and reliable lifting and lowering drive of the coil 60 for the sliding seat 22 in the buffer state.

[0037] During specific implementation, an upper limit mechanism 70 is provided at the top center of the front end surface of the vertical mounting plate 50, and the upper limit mechanism 70 is used to ensure the top limit of the sliding seat 22; a lower limit mechanism 80 is provided at the bottom center of the front end surface of the vertical mounting plate 50, and the lower limit mechanism 80 is used to ensure the bottom limit of the sliding seat; during specific implementation, the upper limit mechanism 70 and the lower limit mechanism 80 both include a mounting seat body 1 and a limit column 2, and the limit column 2 is used to reliably limit the sliding seat 22.

[0038] In a specific implementation, the input guide roller 10 is arranged at a higher position than the output guide roller 30 , so that the buffer guide roller group 20 in the tensioned state of the coil 60 is located between the heights of the input guide roller 10 and the output guide roller 30 .

[0039] When it is working, the coil material is normally conveyed under the tensioned state. When the material needs to be changed, the sliding seat is manually moved to the highest point or the lowest point. When the sliding seat is at the highest or lowest point, the coil material is buffered and conveyed, and the sliding seat gradually rises and falls until the coil material recovers to the tensioned state. During the time when the sliding seat rises and falls, the feeding part of the coil material is quickly replaced. When the coil material needs to be replaced, the entire production line does not need to be shut down, thereby ensuring the normal production of the production line.
