Description

The protective film is generally placed in rolls, so when covering, the protective film needs to be unwound from the roll. However, due to the material characteristics of the protective film itself, direct pulling during unwinding will cause deformation. At the same time, the unwinding roller of the roll will cause excessive unwinding under the action of inertia, and the protective film cannot remain in a tensioned state, which is not conducive to the subsequent separation of the roll.

Other objects, features and aspects of the present disclosure are disclosed in or clear from the following detailed description. It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.

[0019] like Figure 1 and Figure 2 The utility model shows a furniture packaging unwinding device, which comprises a frame 1, at one end of which an unwinding roller 2 is provided, the end of which is connected to an unwinding motor 3, and along the moving direction of the coil when the unwinding roller 2 rotates, an auxiliary conveying mechanism 4 for assisting the unwinding of the coil is provided on the moving path of the coil, and the conveying speed of the auxiliary conveying mechanism 4 is lower than the unwinding speed of the unwinding roller 2; a cutting mechanism 5 is provided at the front end of the auxiliary conveying mechanism 4, and the cutting mechanism 5 adopts a pressing knife which can be raised and lowered on the frame, and the length of the pressing knife is greater than the width of the coil, and when the unwinding length of the coil reaches the set requirement, the pressing knife is moved down to separate the coil.

[0020] When unwinding, the unwinding motor 3 rotates first, so as to avoid the protective film from being tightened when the auxiliary conveying mechanism 4 drives it to move, and the auxiliary conveying mechanism 4 is used to control the total length of the unwinding, and reduce the pulling deformation of the protective film, so as to avoid the problem that the furniture cannot be fully covered and protected due to the size of the protective film.

[0021] In a specific embodiment, the auxiliary conveying mechanism 4 of the utility model includes two groups of conveying rollers 6, and the two groups of conveying rollers 6 are respectively arranged on the upper and lower surfaces of the coil. The conveying roller 6 located at the top is driven by the lifting frames 7 arranged at both ends to move up and down to adjust the distance with the surface of the coil. The lifting frames 7 and the conveying rollers 6 are connected by bearings. The bottom of the lifting frame 7 is connected to the lifting cylinder 9 arranged on the frame 1, and the lifting frame 7 is driven to move up and down by the lifting cylinder 9; the end of the conveying roller 6 located at the bottom is connected to the conveying motor 8, and the driving shaft of the conveying motor 8 is connected to the corresponding conveying roller 6 rotating shaft through a coupling.

[0022] The conveyor located above is set in a liftable form, so that when the material roll is replaced, the end of the protective film can smoothly enter between the two sets of conveyor rollers, and after the installation is completed, the two conveyor rollers are used to clamp the protective film and use the conveyor rollers to drive the protective film forward to achieve smooth unwinding. Anti-slip grooves are set on the surface of the conveyor roller 6 to improve the reliability of transportation and avoid slipping. A counter 10 for detecting the number of rotations of the conveyor roller 6 is set at the end of one of the conveyor rollers 6, so that the length of the conveyed protective film can be accurately known according to the number of rotations.

[0023] When the unwinding device of the utility model is in use, the protective film coil is first installed on the frame 1, and the unwinding roller 2 is driven to rotate by the unwinding motor 3 to release the protective film in advance to a length of a distance at one end, and the end of the protective film is loaded between the conveying rollers 6, and the lifting frame 7 is driven downward by the lifting cylinder 9 to press the protective film between the two conveying rollers, so that the protective film can be conveyed by the rotation of the conveying rollers; then the unwinding motor 3 and the conveying motor 8 are started to unwind the protective film, and when the counter 10 detects that the number of rotations of the conveying roller 6 reaches the set number of rotations, it means that the conveying length of the protective film meets the requirements, the unwinding is stopped, and the cutting mechanism 5 is used to separate the protective film, and the removed protective film can be used to cover the furniture; then the counter is reset to zero, and the next unwinding length is continuously monitored to realize automatic and precise control of the unwinding process.
