The rotating rod is fixedly connected to a threaded rod inside the winding device, and the threaded rod is threadedly connected to the upper and lower support rods. When the threaded rod rotates, the upper and lower support rods move. When the distance between the upper and lower support rods changes, the device can be used for rolls of different specifications. The device is also equipped with a base inside the device, and a fixing rod is provided on one side of the outer surface of the base, making it easy to fix the device on the ground.

[0004] The aforementioned winding rack uses a lifting and movable clamping structure to wind up rolls of different specifications. However, the lifting clamping structure can only accommodate rolls of different thicknesses, not rolls of different lengths, and unloading after winding is inconvenient, thus affecting the winding efficiency. Therefore, we provide a winding rack for film rolls. Utility Model Content

[0005] The purpose of this utility model is to provide a film roll winding rack to solve the problem mentioned in the background art that the existing winding rack uses a lifting movable clamping structure to wind up rolls of different specifications. However, the lifting clamping structure can only meet the needs of winding up rolls of different thicknesses, but cannot meet the needs of winding up rolls of different lengths. Moreover, unloading after winding is inconvenient, which affects the winding efficiency of the roll.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a film roll winding rack, including a winding table, a guide groove is provided inside the winding table, a coupling carrier is provided on one side of the guide groove, the coupling carrier and the winding table are an integral structure, and a winding motor is fixedly provided on the rear end face of the coupling carrier by screws.

[0007] Also includes:

[0008] The take-up roller shaft is located at the front end of the coupling carrier. The output shaft of the take-up motor is connected to the rotating shaft at one end of the take-up roller shaft via a coupling. The take-up roller shaft is externally sleeved with a first limiting ring seat and a second limiting ring seat.

[0009] The branch screw is integrally formed on the outer wall of the first limiting ring seat and the second limiting ring seat. Eight branch screws are respectively provided on the first limiting ring seat and the second limiting ring seat, and an extension stop is sleeved on each of the eight branch screws.

[0011] The movable rotating groove is set on the inner wall of the first limiting ring seat and the second limiting ring seat. There are four movable rotating grooves on the first limiting ring seat and the second limiting ring seat respectively. The inner wall of the movable rotating groove is provided with an outer frame. The inner wall of the outer frame is rotatably connected with rollers through a rotating shaft.

[0012] Preferably, a second connecting rod is welded to the front end face of the second limiting ring seat, and a connecting seat is welded to the lower end of the second connecting rod. An electromagnet is embedded and fixed inside the connecting seat by a nail-free adhesive, and the connecting seat is attracted and connected to the winding table by the electromagnet.

[0013] Preferably, a power connector is provided on one side of the outer wall of the connector, and the output end of the power connector is electrically connected to the input end of the electromagnet.

[0014] Preferably, the extension stop has a threaded groove inside, and the extension stop is movably connected to the branch screw through the threaded groove.

[0017] Preferably, a servo motor is provided at one end of the winding table, and the servo motor is connected to the threaded screw inside the guide groove through a coupling mechanism.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses a winding motor to drive the film roll to wind between a first limiting ring seat and a second limiting ring seat. After winding, the power plug is unplugged to release the magnetic force of the electromagnet, and then the second limiting ring seat is removed from the winding roller shaft. During unloading, the servo motor drives the screw to rotate, and the screw slider drives the first limiting ring seat to move along the winding roller shaft, thereby pushing the wound film roll off the winding roller shaft for unloading. This overcomes the problem that existing winding methods use a lifting movable clamping structure to wind rolls of different specifications, but the lifting clamping structure can only meet the needs of winding rolls of different thicknesses, and cannot meet the needs of winding rolls of different lengths. Moreover, unloading after winding is inconvenient, which affects the winding efficiency of the film roll. Attached Figure Description
