The extruding and laminating machine in the prior art is provided with a winding roller 40, and the winding roller 40 is used for winding a film product formed by extruding, casting and compounding. In the process of winding the film by the winding roller 40, people find that the situation that the film deviates along the axial direction of the winding roller 40 is easy to occur, so that more wrinkles are often caused, and the end face of the wound material end is not flat. When wrinkling occurs, the wrinkled portion is generally removed, which causes waste, and the removal of the wrinkled portion is likely to be performed in a shutdown state, which affects the normal production cycle and reduces the production efficiency.

In order to solve the technical problem, an embodiment of the present application provides a limiting device for winding of an extruder, which includes two sets of limiting rods 10 arranged in parallel, the two sets of limiting rods are arranged at two sides of a film advancing path, and opposite side rod bodies of the two sets of limiting rods 10 are respectively arranged to be attached to two sides of a film wound on a winding roller 40, so that two end surfaces of the film wound on the winding roller 40 are flush.

The film advancing path is a path through which the film is extruded from the casting and conveyed to the winding roller 40, two sides of the film advancing path are two outer sides in the film width direction, and the film width direction is consistent with the axial direction of the winding roller.

The implementation principle of the embodiment is as follows: set up stop device at the side of film route of marcing, restrict the skew of film along film width direction in the course of marcing for the film is after on the winding up roller 40, and the tip terminal surface of coil stock presents the parallel and level state, and the coil stock surfacing moreover. Two groups of limiting rods which are oppositely arranged at two sides of a film advancing path are adopted to attach two side parts of the film on the winding roller.

The utility model provides a stop device is used in winding and unwinding of crowded compound machine, through the two sets of gag lever posts 10 that adopt mutual parallel arrangement, with two sets of gag lever posts 10 mutual disposition in the both sides of film route of marcing, and paste along the axial both sides of spool on the film that two sets of gag lever posts 10 one side pole bodies in opposite directions respectively the winding up of winding up roller 40 and lean on, thereby make the both ends face of the film of winding up on the winding up roller 40 present the parallel and level form, and then the in-process of winding up roller 40 roll-up film among the prior art has been solved, the problem of film along the off tracking of winding up roller 40 axial.

In a specific application scenario, if the contact between the limiting rod 10 and the film is sliding contact, the abrasion to the film product is larger than that of the film product due to rolling contact between the limiting rod and the film, and even if the friction force in the sliding contact mode is not too large, the film product is still damaged. In order to reduce the probability of the occurrence of such a problem, the embodiment further preferably comprises: the limiting rod 10 comprises an installation rod 11 and a roller 12, the roller 12 is matched on the installation rod 11 in a rotating mode, the roller 12 is used for being in rolling contact with two side portions of the film rolled by the rolling roller 40, and the rolling contact mode is favorable for reducing the friction force between the two, so that the film product is protected; wherein, the axial direction of the revolving shaft of the roller 12 is consistent with the rod length direction of the mounting rod 11, and the rod length direction of the mounting rod 11 is vertical to the axial direction of the winding roller 40.

The implementation principle is that the film to be wound by the winding roller 40 is divided along the radial direction, and each area is respectively arranged corresponding to each roller 12, so that the film in each area can be in contact with each roller 12, the friction force between the film in each area, particularly the area close to the axis of the winding roller 40, and the rollers 12 is further reduced, and the probability of damaging the film is further reduced.

Through setting up a plurality of gyro wheels, and the gyro wheel is arranged along the pole length direction interval of installation pole for the rotary motion of each gyro wheel is independent each other, and each gyro wheel is used for the radial different position contact of film coil stock on the winding up roll respectively, thereby is favorable to further reducing the frictional force between film coil stock and the gag lever post along radial different positions on the winding up roll.
