Technical Field

[0001] The utility model relates to the technical field of stretch film packaging machine equipment, in particular to a movable cutter for a stretch film packaging machine. Background Art

[0002] Stretch film packaging machine is a new type of automatic packaging equipment, mainly used to stretch and wrap the stretch film on the surface of the product to form a protective layer. The use of stretch film packaging technology can effectively prevent dust, moisture, preserve freshness and appearance. At the same time, it has the advantages of high efficiency, labor saving and low cost. It is widely used in food, medical, chemical, daily necessities and other industries.

[0003] The stretch film packaging machine needs to cut and divide the product into pieces after packaging. In this step, a movable blade for cutting is required. The current traditional cutting method is to cut separately in the horizontal and vertical directions. This method will prolong the cutting process, and the current movable blades are easily corroded when exposed to a high humidity environment for a long time, thereby reducing their service life. For this reason, we propose a movable cutter for a stretch film packaging machine.

[0004] The prior art has the following problems:

[0005] 1. The active blade of the current stretch film packaging machine needs to be cut in two steps, horizontally and vertically, with slow cutting speed and low output efficiency;

[0006] 2. The movable blades of current stretch film packaging machines are prone to rust and reduce their service life if used in an environment with high humidity. Utility Model Content

[0007] In view of the deficiencies of the prior art, the utility model provides a movable cutter for a stretch film packaging machine, which solves the existing problems of low cutting efficiency and easy rust of the blade.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a movable cutter of a stretch film packaging machine, comprising an equipment body and a blade fixing plate, wherein the blade fixing plate is arranged on one end surface of the inner side of the equipment body through integrated cutting;

[0009] The bottom end of the blade fixing plate is also provided with a longitudinal blade, the same side of the bottom end of the blade fixing plate is provided with a transverse blade, the inner upper end of the longitudinal blade is also provided with a titanium alloy forging layer, and the outer end of the longitudinal blade is also provided with a chrome-plated blade head;

[0010] The transverse blade also includes a connecting groove and a connecting bolt. The connecting groove is opened at the inner end of the transverse blade. The connecting bolt passes through the blade fixing plate and the transverse blade and has a movable connection relationship with the transverse blade.

[0011] As a preferred technical solution of the utility model, the longitudinal blade is shorter than the transverse blade, and the longitudinal blade is the same size as the connecting groove.

[0012] As a preferred technical solution of the utility model, the transverse blade and the longitudinal blade are movably connected to each other through a connecting bolt and cross at 90 degrees, and holes are left at the bottom inner ends of the longitudinal blade and the transverse blade to help the connecting bolt connect.

[0013] As a preferred technical solution of the utility model, the device body and the blade fixing plate are combined into a T-shape as a whole, and need to be assembled with an external stretch film packaging machine before use. The transverse blades and the longitudinal blades are installed at equal distances.

[0014] Compared with the prior art, the utility model provides a movable cutter for a stretch film packaging machine, which has the following beneficial effects:

[0015] 1. The movable cutter of a stretch film packaging machine has a longitudinal blade, a transverse blade, a connecting groove, and a connecting bolt. By inserting the longitudinal blade into the connecting groove, and then penetrating the transverse blade and the longitudinal blade through the connecting bolt, and making the transverse blade and the longitudinal blade maintain a stable connection relationship with each other, the overall cutting blade can be in a cross-shaped shape. The 90-degree right-angle intersection can make the blade cut and cover the material to be cut, and perform an overall cross cutting. Cutting by the cross cutting method can replace the traditional segmented cutting method of first cutting horizontally and then cutting longitudinally, reducing the overall cutting operation process, and increasing the cutting speed and output efficiency.

[0016] 2. The movable cutter of the stretch film packaging machine can increase the overall strength of the blade by arranging a titanium alloy forging layer inside the blade, and can effectively prevent the blade from being corroded by external moisture during cutting operation by arranging a chrome-plated blade head at the outer end of the blade, thereby extending the service life.
