Technical Field

[0001] The utility model relates to the technical field of film bundling, in particular to a film cutting device used in a film bundling machine. Background Art

[0002] In many fields such as medicine, food, workpieces and equipment, products are usually packaged in boxes before leaving the factory for easy collection and transportation.

[0003] However, multiple packaging boxes are relatively scattered and not easy to be stacked together for transportation; therefore, people have come up with the idea of bundling multiple scattered products together through film to facilitate centralized and large-scale transportation.

[0004] The invention patent with publication number CN113682517A discloses a cross film strapping device and method, the device comprising: a strapping table for placing objects to be packaged, the strapping table being capable of rotating 90° based on a connected first rotating drive mechanism; a strapping mechanism comprising a rotating member on which a strapping film roller is provided, the rotating member being capable of rotating around the object to be packaged one circle based on a connected second rotating drive mechanism so that the strapping film on the strapping film roller is wrapped around the object to be packaged; a spot welding mechanism, the spot welding mechanism being capable of welding and connecting two overlapping layers of strapping film after wrapping one circle based on a set hot welding head; a cutting mechanism, the cutting mechanism being capable of cutting the wrapped strapping film based on a set cutter; a controller being capable of controlling the actions of the strapping table, the strapping mechanism, the spot welding mechanism and the cutting mechanism; and the technical problem of film being difficult to strap.

[0005] The above device cuts the film by a cutter, but the cutter structure is relatively simple and has a flat blade, which cannot effectively cut the film completely.

DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0020] Please refer to Figure 1-4 A film cutting device for a film strapping machine includes a partition 1 in the strapping machine, a film roll 2 is provided on one side of the partition 1, and a vertical plate 3 parallel to the partition 1 is provided on the other side, an electric push rod 4 fixed on the partition 1 is provided between the vertical plate 3 and the partition 1, and a telescopic mechanism is provided on one side of the electric push rod 4, wherein the electric push rod 4 can drive the telescopic mechanism to perform linear reciprocating operation, and a cutting mechanism for cutting a film 21 is provided at the outer end of the telescopic mechanism.

[0021] Since the cutting mechanism is arranged at the outer end of the telescopic mechanism, the extension and contraction of the telescopic mechanism can drive the cutting mechanism to move back and forth; when the telescopic mechanism is extended, the cutting mechanism can cut the film 21 and cut the film. When the telescopic mechanism is retracted, the cutting mechanism does not contact the film and makes room for film bundling, and the two do not interfere with each other.

[0022] In the solution of the present utility model, the telescopic mechanism includes a fixed seat 5 fixed on the partition 1, a sleeve 51 on the fixed seat 5 and an optical axis 52 in the sleeve 51. One end of the optical axis 52 is provided with a connecting block 53, and the other end passes through the sleeve 51 and the partition 1 and is provided with a sliding seat 54. When the optical axis 52 is telescoped in the sleeve 51, it drives the sliding seat 54 to move horizontally, and the cutting mechanism is arranged on the sliding seat 54.

[0023] That is to say, when the optical axis 52 extends and retracts in the sleeve 51, it drives the sliding seat 54 to extend or retract. When the optical axis extends, the cutting mechanism cuts the film. When the optical axis retracts, the cutting mechanism does not contact the film and can be used as needed.

[0024] Specifically, a first connecting rod 41 is provided on the outer side of the vertical plate 3, and the output end of the electric push rod 4 passes through the vertical plate 3 and is fixedly connected to the first connecting rod 41. The end of the first connecting rod 41 is provided with a vertical second connecting rod 42, and the end of the second connecting rod 42 is fixedly connected to the connecting block 53; wherein the first connecting rod 41 and the second connecting rod 42 are fixedly connected, and the two are L-shaped. After the electric push rod 4 is running, the optical axis 52 is driven to extend and retract through the first connecting rod 41, the second connecting rod 42 and the connecting block 53; that is, the extension and retraction of the piston rod of the electric push rod 4 drives the optical axis 52 to extend and retract, thereby realizing the linear reciprocating extension and retraction motion of the optical axis 52.

[0025] In the present invention, the cutting mechanism includes a cutting motor 6 and a cutting piece 61, wherein the cutting piece 61 can be a cutting piece or a thin grinding wheel, and the cutting piece 61 is detachably connected to the output shaft of the cutting motor 6, wherein the cutting motor 6 is fixed on the surface of the sliding seat 54.

[0026] When the film 21 needs to be cut, the cutting motor 6 is started and drives the cutting blade 61 to rotate; at this time, when the electric push rod 4 retracts, the optical axis extends in the direction of the partition 1, and the sliding seat 54 and the cutting motor 6 above slide further. When the sliding seat 54 slides in the direction of the film 21, it gradually contacts the film 21, and as the optical axis continues to extend, the film is cut.

[0027] After the film is cut, the cutting motor 6 stops and the electric push rod 4 extends, so that the sliding seat 54 moves closer to the partition 1; this prevents the sliding seat 54 (and the cutting motor 6 and cutting piece 61 above) from affecting the film bundling; when cutting is required, the cutting motor and the electric push rod can be started again, which is easy to use.

[0028] See also Figure 5 As a preferred solution, the cutting piece 61 is detachable from the output shaft of the cutting motor 6 by multiple screws 63 and can be used to replace the cutting piece 61. In addition, a plurality of notches 62 are evenly arranged on the circumference of the cutting piece 61; when the cutting piece 61 rotates at high speed, the establishment of the notches 62 can increase the film cutting speed and make the film cutting more thorough.

[0029] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
