When the adjusting screw rotates, the movable frame moves left and right along the axial direction of the adjusting screw.

[0009] By adopting the above technical solution, with the provision of the adjusting screw, when it is necessary to adjust the left and right positions of the film roll, due to its axial and radial positioning, circumferential rotation, and the characteristic that the movable frame is in threaded connection with it, the operator can rotate the adjusting screw, and the movable frame can move left and right along the axial direction of the adjusting screw, thereby changing the left and right positions of the film roll. The structure is simple, the adjustment is convenient, and there is no need to stop the machine for operation.

[0010] The present utility model is further provided that: the power assembly includes a motor, a driving wheel, and a driven wheel. The motor is arranged on the movable frame, the output shaft at one end of the motor is connected to the driving wheel, the driven wheel is arranged at one end of the rotating shaft, and the driven wheel and the driving wheel are linked by a belt.

[0011] By adopting the above technical solution, the motor drives the driving wheel to rotate, the driving wheel synchronously drives the driven wheel to rotate through the belt, and the rotation of the driven wheel drives the rotating shaft to rotate, so as to drive the film roll to rotate and feed. The structure is simple and the transmission is more stable.

[0012] The present utility model is further provided that: an adjusting shaft is arranged on one side of the movable frame corresponding to the rotating shaft, and adjusting retaining rings are respectively arranged on the left and right sides of the adjusting shaft corresponding to the film roll.

[0013] By adopting the above technical solution, the adjustment shaft is provided to support the film roll, further improving the stability of the film roll placement. The adjustment retaining ring is provided to prevent the axial sliding of the film roll. At the same time, when the equipment is in a shutdown state, the left and right positions of the film roll can also be adjusted by moving the adjustment retaining ring and the film roll, which has strong practicability. Preferably, the adjustment shaft is arranged on the side facing away from the film roll discharging direction, further improving the convenience for the operator to adjust the positions of the retaining ring and the film roll.

[0014] The present utility model is further provided with: a transition shaft is arranged on one side of the machine frame corresponding to the film roll along the film feeding direction.

[0015] By adopting the above technical solution, when the film roll becomes smaller, the film feeding angle is prevented from changing, which affects the subsequent packaging effect. By adding a transition shaft, the film roll is wound out from below the transition shaft for film feeding, so that the film feeding angle will not change with the size of the film roll, further improving the structural reliability.

[0016] The present utility model is further provided with: mounting seats are respectively arranged at both ends of the transition shaft, mounting holes are arranged on the mounting seats, and mounting long slots are provided on the machine frame corresponding to the positions of the mounting holes.
