However, the equipment with a relatively simple structure The film rewinding machine has poor working stability, low working efficiency, and the qualified rate of products cannot be guaranteed, while the automatic film rewinding machine with stable work and high working efficiency often has complex structure, expensive price and high cost.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic film rewinder with simple structure, stable and efficient operation, and low cost in view of the above-mentioned deficiencies in the prior art.

The technical scheme adopted by the utility model is as follows: including a frame, the frame is provided with a discharge roller, a guide roller, a tension roller group, a winding roller and a driving device, and the discharge roller is arranged on the film rewinding path The front end of the front end, the guide roller, the tension roller group and the winding roller are distributed sequentially along the film rewinding path; wherein, the tension roller group includes an upper tension roller and a lower tension roller, and the upper tension roller and the lower tension roller cooperate The clamped film moves along the film rewinding path, and an arc-shaped rotary cutter for cutting the film is arranged above the tension roller group; the driving device is installed under the frame, and the driving device passes through the The synchronous wheel and the driving belt drive the guide roller, the lower tension roller and the winding roller to rotate.

As a further elaboration to the above-mentioned technical scheme:

In the above technical solution, the drive device is a three-phase asynchronous motor or a variable frequency speed regulating motor.

Further, the transmission belt is a synchronous belt or a belt.

Further, a control box is installed on the frame, and the control box is electrically connected to the driving device and controls its operation.

Further, the bottom of the rack is provided with height-adjustable stabilizing feet.

The beneficial effects of the utility model are: the utility model is driven by a motor and driven by a transmission belt, so that the discharge roller, guide roller, tension roller group and winding roller distributed on the rewinding path of the film are rotated sequentially, and the original loose , laminated, wrinkled and other undesirable phenomena, from the unwinding roller through the automatic film rewinding machine to form a certain specification, a certain tightness, and meet the requirements of the finished product. The automatic film rewinding machine also has an arc-shaped rotary cutting machine for cutting the film Knife; the utility model has the advantages of simple structure, stable and efficient work, and low cost.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1-2, the technical scheme that the utility model takes is as follows: Comprising frame 1, described frame 1 is provided with discharge roller 2, guide roller 3, tension roller group 4, winding roller 6 and drive Device 5, the discharge roller 2 is arranged at the front end of the film rewinding path, the guide roller 3, the tension roller group 4 and the winding roller 6 are distributed sequentially along the film rewinding path; wherein the tension roller group 4 It includes an upper tension roller 8 and a lower tension roller 9, the upper tension roller 8 and the lower tension roller 9 cooperate to clamp the film 14 and move along the film rewinding path, and the top of the tension roller group 4 is also provided with a device for cutting the film 14 Arc-shaped rotary cutter 10; the driving device 5 is installed under the frame 1, and the driving device 5 drives the guide roller 3 through the synchronous wheel 11 installed on its rotating shaft and the transmission belt 7 , the lower tension roller 9 and the winding roller 6 rotate; the discharge roller 2, the guide roller 3, the tension roller group 4 and the winding roller 6 are arranged parallel to each other, and are arranged on the complex of the film 14 in sequence. On the winding path, the rewinding path of the film 14 starts from the unwinding roller 2 and passes successively below the guide roller 3, below the lower tension roller 9, between the upper tension roller 8 and the lower tension roller 9, and above the upper tension roller 8. , and finally rewind from the bottom of the winding roller 6; the driving device 5 rotates counterclockwise during work, and its rotating shaft drives the synchronous wheel 11 and the transmission belt 7 to also rotate counterclockwise, and the transmission belt 7 rotating counterclockwise will drive the guide roller 3, The lower tension roller 9 and the winding roller 6 rotate counterclockwise, and the lower tension roller 9 that rotates counterclockwise will also drive the upper tension roller 8 to rotate clockwise, which provides a driving force for the film 14 to make it move along the above-mentioned complex process.
