[0016] The technical solution of the application will be further illustrated by the embodiment in combination with the drawings.

[0017] Please refer to Figs. 1 to 4As shown, in the embodiment, the automatic roll changing mechanism for automobile roof wet line comprises a rack 1, a material laying platform 2, two lifting cylinders 3, two telescopic cylinders 4, a first roller assembly and a stacking roller assembly. The material laying platform 2 is arranged on the top of the rack 1. Two support wall plates 5 are fixed on the rack 1 at the two ends of the material laying platform 2. The two lifting cylinders 3 are fixedly installed on the two support wall plates 5 respectively, and the driving rods are arranged downward. Two first linear guides 6 extending along the height direction are fixed on the inner side walls of the two support wall plates 5 correspondingly. The first roller assembly comprises two first end plates 7, a first roller 8 and a first roller driving motor 9. The first roller 8 is rotatably assembled between the two first end plates 7. The first roller driving motor 9 drives the first roller 8 to rotate. The two first end plates 7 are assembled on the first linear guides 6 through sliding blocks. The driving rod of the lifting cylinder 3 is connected to the first end plate 7, so as to drive the whole first roller assembly to move up and down along the first linear guide 6.

[0018] The two telescopic cylinders 4 are fixed on the outer side walls of the two support wall plates 5 along the horizontal direction. Two second linear guides 10 extending along the horizontal direction are fixed on the inner side walls of the two support wall plates 5 correspondingly. The second roller assembly comprises two second end plates 11, a second roller 12 and a second roller driving motor 13. The second roller 12 is rotatably assembled between the two second end plates. The second roller driving motor 13 drives the second roller 12 to rotate. The two second end plates 11 are assembled on the second linear guides 10 through sliding blocks. The connecting plates 14 are fixed on the two second end plates 11 respectively. The connecting plates 14 pass through the corresponding support wall plates 5. The driving rod of the telescopic cylinder 4 is connected to the connecting plate 14, so as to drive the whole second roller assembly to move forward and backward along the second linear guide 10, so as to move close to or away from the first roller assembly. The avoiding holes 15 for avoiding the connecting plates 14 are arranged on the support wall plates 5.

[0019] In work, the first roller 8 and the second roller 12 are respectively threaded with the fabric. When the fabric on the first roller 8 is used up, the lifting cylinder 3 lifts the first roller 8, and the telescopic cylinder 4 pushes the second roller 12 forward. At this time, the second roller 12 moves to the position of the original first roller 8 on the material laying platform 2 (the fabric also moves to the corresponding position). At this time, the switching of the first roller 8 and the second roller 12 is completed. The line body continues to produce without stopping the line. When the personnel outside the line replenish the fabric of the first roller 8, the above-mentioned action is repeated to realize the roll changing without stopping the line.

[0020] The above embodiment only illustrates the basic principle and characteristics of the present application. The present application is not limited by the above examples. Various changes and modifications can be made without departing from the spirit and scope of the present application. These changes and modifications fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
