As shown in the figure, the receiving and pressing roller mechanism 3 of this embodiment includes a first swing arm 34 pivotally connected to the frame 1, and a first air cylinder 31 installed on the frame 1 to drive the first swing arm 34 to swing. , the second swing arm 38 pivoted on the first swing arm 34, the second cylinder 35 mounted on the first swing arm 34 to drive the second swing arm 38 to swing, and the second cylinder 35 installed at the end of the second swing arm 38 Pressure roller 39, said cutting knife mechanism 4 includes a cutter 42, a cutter frame 41 and a third air cylinder 43, the cutter frame 41 is pivotally connected to the end of the first swing arm 34, the first The three cylinders 43 are installed on the first swing arm 34, and the third cylinder 43 drives the cutter frame 41 to swing along the pivot. When needing to receive material, the first swing arm 34, the second cylinder 35, the second swing arm 38 and the cutting knife mechanism 4 that are mounted on the first swing arm 34 are moved closer to the material roll by the first cylinder 31. To a certain extent, the second swing arm 38 drives the pressure roller 39 through the second cylinder 35 to completely bond the material tape to the new material roll 7, and at the same time, the third cylinder 43 works to drive the cutter frame 41 to swing to make the cutter Knife 42 cuts off the material strip between the pressure roller 39 and the material roll on the material roller shaft 63 . The utility model certainly also can not establish the first swing arm 34 and the first cylinder 31, and when needing to change the connection material, directly utilize the second cylinder 35 to drive the second swing arm 38 to push the material belt to the new material coil 7 places and It is close to bonding, but the first swing arm is provided to increase the working distance of the material receiving roller mechanism 3, which can be applied to the occasions of various material rolls with large diameter differences.

The other end of the connecting rod 32 is fixedly connected with the pivot 33 through the tension sleeve 8, and the pivot 33 is fixedly connected with the first swing arm 34 through the tension sleeve 8; the second cylinder 35 is pivotally connected to the first On the swing arm 34, the end of the telescopic rod of the second cylinder 35 is pivotally connected with the connecting rod 36, and the other end of the connecting rod 36 is fixedly connected with the pivot 37 through the tension sleeve 8, and the pivot 37 is connected with the second swing arm 38 through The radial locking screw is fixedly connected and fixedly connected: the cylinder body of the third cylinder 43 is pivotally connected to the end of the first swing arm 34 close to the frame, and the end of the telescopic rod of the third cylinder 43 is connected with a connecting rod 44 is pivotally connected, the other end of the connecting rod 44 is rotatably sleeved on the pivot 37, a connecting rod 45 is arranged between the connecting rod 44 and the cutter frame 41, and one end of the connecting rod 45 is pivotally connected to the pivot of the connecting rod 44. Between the shaft 46 and the pivot 37 , the other end is pivotally connected to the cutter frame 41 .

In the illustration, the guide wheel (2) is coaxially connected with the pivot (33).

The working process of the present embodiment is as follows: when the roll is not changed, the material tape of the material roll on the left enters the coating production line by directly passing through the rollers 2, 9, 10. When the material roll is about to be unwound, The sensor gets a signal so that the motor moves and drives the rotating arm 62 to turn clockwise 180 degrees, so that the unrolled material roll is rotated to the upper right position, and the material belt 11 of the material roll passes through the rollers 5, 2, 9, 10 and enters the coating In the production line, the new material roll is rotated to the lower left position (that is, at the raw material roll exchange position). The axis of the pivot shaft rotates clockwise, and the rotation of the pivot shaft 33 drives the first swing arm 34 to rotate clockwise to make its end close to the material roll 7. When it closes to a certain degree, the first cylinder 31 stops moving, and the second cylinder 31 stops when receiving the material. 35 starts to move and pulls the connecting rod 36 to rotate clockwise along the axis of the pivot 37. At the same time, the pivot 37 drives the second swing arm 38 to rotate clockwise, thus driving the pressure roller 39 to press down so that the material tape is closely bonded to the new material. On the tape head of roll 7, at the same time, the third cylinder 43 starts to work to drive the connecting rod 44 to rotate clockwise along the pivot 37, and the clockwise rotation of the connecting rod 44 pushes the connecting rod 45 to move to the right, and the connecting rod 45 drives the cutter The frame 41 rotates counterclockwise along the pivot, so it drives the cutter to cut off the material tape downwards, so the material tape in the coating production line is provided by a new material roll, that is, the action of changing rolls and feeding is completed, and the whole process does not need to stop. Does not affect the speed of coating.

Of course, the above-mentioned embodiments in conjunction with the accompanying drawings are only to better illustrate the present utility model, and are not intended to limit the protection scope of the present utility model. within the scope of protection of utility models.
