Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product packaging equipment, in particular to an automatic film strapping machine. Background Art
[0002] Film strapping machine is a kind of equipment that can wrap objects with film to achieve packaging and bundling. Generally, before the product leaves the factory, it is necessary to wrap the body or the outer surface of the packaging shell with multiple layers of film. It can bundle multiple products to ensure that the products will not be scattered during transportation, which is convenient for statistics, sorting and handling. The efficiency of multi-layer film wrapping is very low if it relies solely on manpower. The film strapping machine can replace manpower and quickly complete the wrapping and bundling work.
[0003] Although the existing film strapping machines can automatically complete the wrapping work, most of them require manpower to press the end of the film on the surface of the product object and cooperate with the rotation of the equipment. The film can only be loosened after it is wrapped around and covers the end, which is very inconvenient and has certain safety hazards.
[0004] In order to solve the above problems, we have made improvements and proposed an automatic film strapping machine. Utility Model Content

[0023] The auxiliary component 8 includes a clamping component 12. The center of the top surface of the pressure plate 10 is fixedly welded to the connecting plate 9 through a connecting column. There are two clamping components 12, which are respectively fixedly connected to the left and right ends of the top surface of the pressure plate 10 by bolts. The left end of the top surface of the pressure plate 10 is fixedly installed with a second motor 11 by bolts. A transmission shaft is rotatably connected between the two clamping components 12, and the transmission shaft is located below the connecting plate 9.
[0024] The clamping assembly 12 includes a guide rail 13. At the top inside the guide rail 13, a threaded rod 14 is rotatably installed. The thread directions of the two threaded rods 14 are opposite. The threaded rods 14 between the two clamping assemblies 12 are coaxially and fixedly connected through a transmission shaft. The left end of the threaded rod 14 of the clamping assembly 12 on the left end is coaxially and fixedly connected to the rotating shaft of the second motor 11. A moving block 15 is slidably connected to the surface of the guide rail 13. A mounting plate 16 is fixedly welded to the front surface of the moving block 15. The mounting plate 16 is a long strip-shaped plate.
[0025] The opposite surfaces of the two mounting plates 16 are respectively fixedly connected to the two electric slide rails 17 through bolts.

[0027] Working principle: When using this automatic film bundling machine, first stack the items to be wound and bundled in the center of the top surface of the rotating plate 2. Start the lifting rail 4 to raise the bundling film roller 5 to a certain height until it is level with the items. Pull out the film for bundling and winding from the bundling film roller 5 and press it on the side surface of the top of the items. Then control the electric telescopic rod 7 to lower the auxiliary assembly 8 until the pressing plate 10 abuts against the top surface of the items. Drive the auxiliary clamping plate 18 to descend through the clamping plate through-hole 19 through the electric slide rail 17. Then drive the auxiliary clamping plates 18 to approach each other through the second motor 11 until the film is pressed on the surface of the items. At this time, release the hand and start the first motor 3 to drive the rotating plate 2 to rotate and automatically start winding the film. After completing one circle of winding, drive the auxiliary clamping plate 18 to rise and withdraw. The regular square pyramid anti-sticking patterns can effectively prevent the film from adhering to the outer surface of the auxiliary clamping plate 18. Finally, drive the bundling film roller 5 to slowly descend at the same time, and the film bundling and winding work can be automatically completed.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
