[0001] The utility model relates to the technical field of film covering, in particular to a laser positioning mechanism for replacing a film roll on a film covering machine. Background Art

[0002] At present, film covering machines are used in various packaging and palletizing industries. The automatic film covering machine equipment operates by supplying film rolls to cover and seal various sizes of pallets. Due to the heavy weight of the film roll and the relatively high installation position of the film roll, it is usually necessary to replace the film roll by an overhead crane or forklift. However, due to the installation position and height, the installation positioning is very difficult, and it requires manual repeated inspection and adjustment to correctly install the film roll. Summary of the invention

[0003] The utility model provides a laser positioning mechanism for replacing a film roll on a film covering machine in order to overcome the deficiencies of the prior art.

[0005] The left and right sides of the upper end of the laser positioning hook are respectively connected to the slings.

[0006] A locking plate is arranged on the outside of the sling, and the sling is fastened to the outside of the laser positioning hook by bolts.

[0007] The laser light is located directly below the first transparent acrylic plate or the second transparent acrylic plate.

[0008] A metal plate is arranged between the transparent acrylic plate 1 and the transparent acrylic plate 2 to isolate the light source.

[0009] The lower end of the laser positioning hook, the first transparent acrylic plate and the second transparent acrylic plate are all arc structures.

[0010] The laser lamp is fixed on the frame of the film covering machine through a laser lamp mounting bracket.

[0011] The left and right ends of the film roll installation shaft are respectively sleeved with film roll installation sleeves.

[0012] The film roll is sleeved on the film roll installation shaft.

[0013] Compared with the prior art, the utility model positions the film roll installation, simplifies the operation method, is convenient and fast, and improves the efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below with reference to the accompanying drawings. Example

[0022] like Figures 1 to 7 As shown, laser positioning hooks 3 are respectively provided at the left and right ends of the film roll installation shaft 1.2, and transparent acrylic plates 1 3.1 and 3.2 of different colors are respectively provided on the left and right sides of the lower end of the laser positioning hook 3, and laser lights 4.1 are provided below the transparent acrylic plates 1 3.1 and 3.2.

[0023] The left and right sides of the upper end of the laser positioning hook 3 are respectively connected to the sling 3.4. The sling 3.4 cooperates with the crane or the trolley to lift the film roll to the film roll installation position of the film covering machine 2.

[0024] A locking plate 3.3 is provided on the outside of the sling 3.4, and the sling 3.4 is fastened to the outside of the laser positioning hook 3 by bolts.

[0025] The laser light 4.1 is located directly below the transparent acrylic plate 1 3.1 or the transparent acrylic plate 2 3.2. When in use, the laser light 4.1 and the transparent acrylic plate 1 3.1, or the laser light 4.1 and the transparent acrylic plate 2 3.2 correspond to the correct installation position. The other transparent acrylic plate is in the wrong installation position. After the laser light is irradiated, if the transparent acrylic plate in the wrong position emits colored light, it can be known that the film roll is installed in the wrong position.

[0026] Transparent acrylic sheet 1 3.1 and transparent acrylic sheet 2 3.2 are transparent acrylic sheets of different colors. When the laser light beam 4.2 emitted by the laser light 4.1 is irradiated, transparent acrylic sheet 1 3.1 and transparent acrylic sheet 2 3.2 emit light of different colors, which is convenient for distinguishing whether the film roll is installed in the correct position. In this embodiment, transparent acrylic sheet 1 3.1 is the correct installation position and uses blue light, and transparent acrylic sheet 2 3.2 uses yellow light. When the laser light beam 4.2 emits yellow light after irradiation, it can be known that the film roll is installed in an incorrect position.

[0027] A metal plate 3.5 is provided between the transparent acrylic plate 1 3.1 and the transparent acrylic plate 2 3.2 to isolate the light source.

[0028] The lower end of the laser positioning hook 3, the transparent acrylic plate 1 3.1, and the transparent acrylic plate 2 3.2 are all arc structures.

[0029] The laser lamp 4.1 is fixed on the frame 2.1 of the film-making machine 2 through the laser lamp mounting bracket 4.

[0030] The film roll 1 is sleeved on the film roll installation shaft 1.2. The left and right ends of the film roll installation shaft 1.2 are sleeved with film roll installation sleeves 1.1 respectively, and the installation sleeves 1.1 are lifted by the laser positioning hooks 3.

[0031] When this embodiment is used, the film roll 1 is lifted by the sling 3.4, and the position is adjusted so that it moves to the correct position above the film covering machine 2. At this time, the laser beams 4.2 emitted by the left and right laser lights 4.1 simultaneously shine on the transparent acrylic plates on both sides of the film roll 1. When the acrylic plates on both sides of the film roll show blue at the same time, the installation position is correct. When the transparent acrylic plate only emits monochromatic light or yellow light, the installation position is incorrect. Adjust until both left and right emit blue light. Then the crane or trolley slowly lowers the film roll 1 to the installation position of the main body of the film covering machine 2. Withdraw the trolley or crane, untie the sling, and the installation is complete.
