The roll changing device comprises a central shaft 11, a swing arm 12 and a roll changing cylinder 13.
The roll changing roller 1 is arranged on one side of the central shaft 11 through the swing arm 12; the roll changing cylinder 13 is mounted on the fixed disc 3 and connected with the central shaft 11, and the roll changing cylinder 13 drives the central shaft 11 to rotate; when the central shaft 11 rotates, the central shaft 11 drives the roll changing roller 1 to be close to or far away from the air inflation shaft 2 through the swing arm 12.
The reel-changing cylinder 13 comprises a cylinder connecting arm 130, the cylinder connecting arm 130 is connected with the central shaft 11, and the reel-changing cylinder 13 drives the central shaft 11 to rotate through the cylinder connecting arm 130.
In the present embodiment, when the user needs to switch the air shaft 2 to wind the casting film, the roll changing cylinder 13 is turned on, and the roll changing cylinder 13 drives the central shaft 11 to rotate through the cylinder connecting arm 130. The central shaft 11 drives the winding roller 1 to rotate and swing around the central shaft 11 through a swing arm 12, so that the winding roller is attached to the casting film roll. The central shaft 11 is fixed on the fixed disc 3, the central shaft 11 only rotates along with the fixed disc 3 to move, the influence of the movement of the air inflation shaft 2 and the roll changing roller 1 is avoided, and the roll changing roller 1 can accurately swing to a casting film roll of the air inflation shaft 2.
The roll changing device comprises a driving wheel 141, a transmission shaft 14, a transition wheel 142, a transmission wheel 10 and a synchronous belt 15, and the structural connection relation and the installation relation are as follows:
the transmission shaft 14 is mounted on the fixed disk 3 through a bearing, and the driving wheel 141 and the transition wheel 142 are mounted at two ends of the transmission shaft 14; the transition wheel 142 is connected with the driving wheel 10 through a synchronous belt 15; the driving wheel 10 is arranged at one end of the reel changing roller 1; the motor can drive the driving wheel 141 to rotate, and further drive the winding changing roller 1 to rotate.
In the present embodiment, the mounting of the drive motor of the change roller 1 on the side of the change roller 1 easily causes the restriction of the casting film take-up space. Therefore, the driving motor of the roll changing roller 1 and the roll changing roller 1 are arranged on two sides of the fixed disc 3, and the driving motor needs to penetrate through the fixed disc 3 to be connected with the roll changing roller 1. Therefore, the utility model discloses in adopt transmission shaft 14 to install on the fixed axle, driving motor passes through the action wheel 141 and the transition wheel 142 at transmission shaft 14 both ends and is connected with the change winding up roller 1.
In order to prevent the position of the central shaft 11 from shifting or moving in the process of driving the central shaft 11 by the roll changing cylinder 13, the cylinder connecting arm 130 of the roll changing cylinder 13 is connected with the transmission shaft 14, the axial center of the transmission shaft 14 and the axial center of the central shaft 11 are in the same straight line, the axial centers of the central shaft 11 and the transmission shaft 14 are collinear, and therefore the roll changing roller 1 is positioned on one side of the axial line of the transmission shaft 14. In order to guarantee that the transmission shaft 14 plays the drive effect to the change winding up roller 1, the utility model discloses at 1 one end installation drive wheel 10 of change winding up roller, at drive wheel 10 and cross the ferryboat 142 between installation hold-in range 15, realize changing the purpose that winding up roller 1 received the driving motor drive rotation. In particular, in this embodiment, the user can use the same motor to drive the driving wheels 141, so as to drive the winding rollers 1 by a single motor, thereby facilitating the user to adjust the rotation speed of the winding rollers 1 by a single motor.
Further, in order to facilitate the adjustment of the rotation speed of the winding roller 1 or the disconnection of the driving motor, the driving wheel 141 is connected with the transmission shaft 14 through a clutch 16, and when the clutch 16 disconnects the driving wheel 141 from the transmission shaft 14, the winding roller 1 can be stationary or rotate under the friction force.
In this embodiment, in the process that the casting film is wound by the inflatable shaft 2, the roll changing roller 1 and the inflatable shaft 2 rotate simultaneously, and the roll changing roller 1 plays a role in flattening and extending the casting film in winding. In the roll changing process, the air inflation shaft 2 and the roll changing roller 1 of the casting film to be rolled are close to the casting film, and the casting film is wound on a paper tube on the air inflation shaft 2 after passing through the roll changing roller 1. The active rotation of the roll changing roller 1 is contacted with the casting film, so that the problem that the casting film is stretched due to the friction force generated by the contact of the casting film and the roll changing roller 1 can be prevented, and the damage or stretching deformation of the casting film caused by the damage of the casting film caused by the roll changing roller 1 can be avoided. After the air expansion shaft 2 finishes sleeving the paper tube to roll the cast film, the fixed disc 3 rotates to switch the air expansion shaft 2, the roll changing roller 1 is close to the air expansion shaft 2 and is attached to the rolled cast film, the clutch 16 is disconnected at the moment, and the roll changing roller 1 rotates relative to the air expansion shaft 2 under the action of friction force of the cast film. At this moment, the casting film has already finished the paper tube rolling, and the casting film changes 1 rotations of winding up roller through frictional force friction and can not stretch the casting film and cause the casting film to warp, and changes winding up roller 1 and can paste repeatedly and press the casting film and make the casting film end be close to the casting film book, guarantees the compactness of casting film rolling, is favorable to the storage and the transportation of casting film book.
Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
