[0030] The working principle and beneficial effects of the above technical solution are:

[0031] The produced bubble film passes through the film supporting mechanism 2, the point breaking mechanism 3, the swing rod mechanism 4 to the winding roller in sequence, completing the point breaking of the bubble film. The bubble film is point broken and wound online, thereby improving production efficiency.

[0032] In one embodiment, Figure 2-4 As shown, the point breaking mechanism 3 includes:

[0033] A supporting component 31 installed on the support 1, a breaking component 32 facing the supporting component 31 and arranged above the supporting component 31, and a driving component 33 for driving the breaking component 32 to rise and fall;

[0034] The supporting member 31 comprises a supporting plate 311 arranged along the width direction of the support 1, and rubber pads 312 are installed in parallel on the supporting plate 311, and the rubber pads 312 are locked on the supporting plate 311 by bolts;

[0035] The point breaking component 32 includes a guide rod 321 slidably mounted on both sides of the support 1, a pressure plate 322 is mounted on the upper end of the guide rod 321, a point breaking knife 323 is mounted on the lower end of the pressure plate 322, and the lower end of the guide rod 321 is connected to the driving component 33; specifically, in order to ensure the verticality of the vertical movement of the guide rod 321, two groups of bearing seats are vertically arranged and spaced apart on the support 1 along the guide rod 312, and the guide rod 321 is penetrated in the bearing seat;

[0036] The driving component 33 includes a crank slider mechanism 331 connected to the guide rod 321 and a transmission shaft 332 for driving the crank slider mechanism 331 to move. The transmission shaft 332 is driven to rotate by a motor 333, and the motor 333 is a stepping motor. The guide rod 321 is fixedly connected to the slider of the crank slider mechanism 331, and the transmission shaft 331 is fixedly connected to the crank of the crank slider mechanism 331. The crank can rotate around the transmission shaft 331 in a whole circle, thereby driving the guide rod 321 to move back and forth vertically.

[0037] The working principle and beneficial effects of the above technical solution are:

[0038] The bubble film is transferred to the supporting component 31 through the film supporting mechanism 2, and the motor 333 is started. Its output shaft drives the transmission shaft 332 to rotate, and the crank connected thereto rotates synchronously. At the same time, the slider drives the guide rod 321 to move vertically, and the guide rod 321 drives the breaking knife 323 to contact the rubber pad 312, so as to instantly break the bubble film and ensure the quality and accuracy of the breaking.

[0039] In one embodiment, the point breaking mechanism 3 further includes:

[0040] The protective component 34 is provided with an elastic member installed on the guide rod 321, and the other end of the elastic member is installed on the support 1. Specifically, the elastic member is set as a spring;

[0041] The working principle and beneficial effects of the above technical solution are:

[0042] The guide rod 321 needs to overcome the pulling force of the elastic member when pressing down vertically to break the point. When the driving component 33 fails, it can also avoid the point breaking knife 323 moving downward to cause damage to the staff's hands, thereby improving the convenience and safety of the point breaking machine.

[0043] In one embodiment, the bottom of the pressing plate 322 has a mounting groove, the point breaking knife 323 is configured in a sheet shape and fixed in the mounting groove by a fastener, and a plurality of the point breaking knives 323 are arranged in parallel along the mounting groove;

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The point breaking knife 323 is clamped in the installation groove of the pressure plate 322, with precise limiting. The point breaking knife 323 is installed in parallel in multiple pieces, which reduces the difficulty of making the point breaking knife 323, saves enterprise costs, and facilitates replacement and maintenance.

[0046] In one embodiment, Figure 5 As shown, the film supporting mechanism 2 is provided with a guide shaft 21 and a pressure roller 22. The packaging film enters the pressure roller 22 through the guide shaft 21 to the supporting component 31. The outlet height of the pressure roller 22 is flush with the upper end surface of the supporting component 31.

[0047] The working principle and beneficial effects of the above technical solution are:

[0048] The packaging film is fed along the feeding direction to the film supporting mechanism 2, and is transported to the supporting component 31 via the guide shaft 21 and the pressure roller 22 for point breaking. The guide shaft 21 and the pressure roller 22 provide a certain tension and horizontal position stability for the film feeding and point breaking of the packaging film, which helps to ensure the accuracy and efficiency of the point breaking operation.

[0049] In one embodiment, Figure 6 As shown, the rocker mechanism 4 includes:

[0050] A support arm 41 is rotatably mounted on the support 1, and a plurality of support rollers 42 and a force-applying component 43 are arranged along the length direction of the support arm 41. The two ends of the force-applying component 43 are respectively hinged on the support 1 and the support arm 41. The force-applying component 43 is a cylinder, and the support arm 41 is swung in the left and right directions by the extension and contraction of the cylinder;

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] The rocker mechanism 4 is arranged on the conveying path before the packaging film is cut and enters the winding roller, and is used for adjusting the tension change when the packaging film is rolled and fed. Specifically, in order to ensure that the packaging film always fits the several support rollers 42, the packaging film is wound around the several support rollers 42 in a reverse direction, and the support arm 41 swings left and right through the extension and contraction of the force-applying component 43. As the angle of the support arm 41 changes, the packaging film is tightened and fits tightly to the support roller 42. The tension of the packaging film can be adjusted at any time as needed to avoid looseness or excessive tightness, thereby ensuring the packaging film rolling and feeding effect.
