A first support rod is fixedly connected to one side of the top of the device base. A first roller is movably connected to the end of the first support rod away from the device base via a bearing. A second support rod is fixedly connected to the top of the device base away from the first support rod. A second roller and a driven roller are movably connected from top to bottom on the outer surface of the second support rod via bearings. The driven roller is located above the second roller. This cutting device for plastic film processing has a simple structure and is easy to operate. It can realize the horizontal and vertical adjustment of the cutting blade, which is convenient for operators to use, ensures the flatness of the cut of plastic film, reduces the wear of the cutting blade during cutting, and increases the service life of the cutting blade, thus having high practicality.

[0004] The cutting equipment used for plastic film cutting in the above-mentioned scheme and existing technology usually only has a single cutting function. When producing plastic bags of different widths, it is necessary to add a cutting device with adjustable size in advance to cut the width of the plastic film. It is impossible to achieve both cutting the width of the plastic film and cutting the horizontally sealed plastic bags in one machine. There is a lack of a corresponding cutting structure that can both adjust the size and perform secondary cutting, which needs to be improved and optimized. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 5 The present invention provides the following two preferred embodiments:

[0022] Example 1: A cutting blade structure for cutting plastic film includes a cutting blade body 1, a horizontal blade 2 fixedly connected to the lower end of the cutting blade body 1, connecting pins 3 fixedly connected to both ends of the cutting blade body 1, a sliding groove 4 provided in the middle of the cutting blade body 1, two sets of vertical cutting blade assemblies 5 being engaged in the sliding groove 4; a scale 401 provided in the sliding groove 4, and multiple sets of cross grooves 402 provided in the sliding groove 4; the cross grooves 402 are located below the non-integer scale of the scale 401.

[0023] In use, the connecting pins 3 at both ends of the cutter body 1 are connected to the vertical hydraulic telescopic devices at both ends of the cutting equipment. During the up-and-down movement of the hydraulic device, the horizontal blade 2 completes the horizontal cutting of the horizontally sealed plastic film. The sliding slot 4 set in the middle of the cutter body 1 is used to slide and insert the vertical cutter assembly 5. The cross slot 402 is used to lock and fix the vertical cutter assembly 5 after it has been slidably adjusted to the correct size. Since the width of plastic bags processed in the market is usually taken as an integer, the cross slot 402 set below the non-integer scale of the scale 401 and its insertion and fixation with the vertical cutter assembly 5 will not affect the adjustment of the size between the two vertical cutter assemblies 5.

[0024] Example 2: Based on Example 1, the vertical cutter assembly 5 includes a locking block 501. A vertical blade 502 is fixedly connected to the lower end of the locking block 501. Two sets of locking block grooves 503 are provided in the middle of the locking block 501. A cross-shaped locking block 504 is inserted into the groove 503. A connecting column 505 is fixedly connected to one end of the cross-shaped locking block 504. A connecting spring 506 is fixedly connected to one end of the cross-shaped locking block 504. A cross-shaped rubber pad 507 is fixedly connected to the other end of the cross-shaped locking block 504. One end is fixedly connected to one end of the locking block groove 503, and one end of the connecting column 505 is fixedly connected to a connecting handle 508; the initial position of the connecting spring 506 keeps the connected cross locking block 504 in a position that is just fully extended out of the locking block groove 503, and the position of the locking block groove 503 corresponds to the cross locking slot 402; the middle of the locking block 501 is provided with a scale reading groove 509, and the lower middle of the scale reading groove 509 is provided with a calibration pointer 510, which corresponds to the integer position of the scale 401.

[0025] In use, the vertical cutter assembly 5, inserted at the front end of the cutter body 1, can pre-cut the plastic bag vertically on both sides. The vertical blade 502 at the lower end of the vertical cutter assembly 5 is relatively long. Even when the vertical hydraulic telescopic devices on both sides of the cutting equipment are in the high position, the vertical blade 502 can still vertically cut the conveyed plastic film. After the vertical cutting is completed, the horizontal blade 2 cuts the sealed plastic film horizontally downwards. Finally, the sealing equipment completes the sealing of the two vertical sides. The scale reading groove 509 set on the vertical cutter assembly 5 can be used to read the scale 401. The calibration pointer 510 is located at the center position of the vertical blade 502 and can be used to align the calibration pointer 510 with the integer scale position on the scale 401. After completing the positioning and size adjustment of the vertical cutter assembly 5, before sliding the vertical cutter assembly 5 into the sliding slot 4, pull the connecting handle 508 to pull the two sets of cross blocks 504 into the block column groove 503. After inserting the block 501 into the sliding slot 4 and adjusting to the required size, loosen the connecting handle 508. The two cross blocks 504 are pressed into the cross slot 402 under the restoring action of the connecting spring 506. The cross rubber pad 507 fixed at the end of the cross block 504 increases the friction between the cross block 504 and the cross slot 402, increasing the firmness of the vertical cutter assembly 5 insertion. When vertical cutting is not required, simply pull the connecting handle 508 to slide it out of the sliding slot 4 to complete the disassembly of the vertical cutter assembly 5.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
