[0034] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.

[0035] See also Figure 1-3 The present disclosure provides an embodiment: a packaging cutting structure of a rolling cutting and applying packaging machine capable of positioning and cutting, comprising a support arm 1, a slideway 2, a telescopic arm 3, an air duct 4, an air jet pipe 5, a tool assembly, and a positioning assembly; the support arm 1 has two groups and is respectively installed on both sides of a frame of the packaging machine, one end of the support arm 1 is driven to rotate by a motor installed in the packaging machine, the other end of the support arm 1 is provided with a slideway 2, the telescopic arm 3 is slidably connected in the slideway 2, an air duct 4 and a tool assembly connected to an external blower are installed between the upper ends of the telescopic arm 3, and an opposing tool is provided on the outer wall of the air duct 4 The component supplies air through the jet pipe 5, and the tool assembly is provided with four blades 603 which are used in a rolling manner. Two positioning components for pressing and locking the patch package are symmetrically installed on the air duct 4. The motor installed in the patch packaging machine drives the support arm 1 to rotate and fall, driving the telescopic arm 3 and the tool assembly therebetween to squeeze and cut the patch package below. While cutting, the positioning components are pressed and locked on both sides of the patch package. After the tool assembly is lifted, the external blower supplies air into the air duct 4, and sends it out to the blade of the tool assembly through the jet pipe 5 to remove the debris.

[0036] See also Figure 1-4 In this embodiment, a screw motor 8 is embedded in the support arm 1, and the screw of the screw motor 8 is in the slideway 2. The telescopic arm 3 is a hollow structure and has a screw sleeve threadedly connected to the screw at the bottom. The telescopic arm 3 moves along the slideway 2 through the screw sleeve transmission. The screw motor 8 drives the screw to rotate. The telescopic arm 3 uses the screw sleeve driven by the bottom of the telescopic arm 3 and the screw to change the rotation direction of the screw. The axial movement of the telescopic arm 3 in the slideway 2 makes the telescopic arm 3 enter and exit the slideway 2, thereby changing the distance of the tool assembly relative to the packaging machine frame.

[0037] See also Figure 5In this embodiment, the tool assembly includes a bracket 601, a sleeve 602, and a blade 603; the bracket 601 is fixedly connected to the top of the telescopic arm 3, and a cylindrical sleeve 602 covered with rubber is arranged between the brackets 601. Four sets of blades 603 are installed on the sleeve 602, and the angle between adjacent blades 603 is ninety degrees. When one blade 603 cuts the dressing package vertically downward, the other blades 603 are above the dressing package. The sleeve 602 adjusts and switches each blade 603 by rotation to cut the dressing package continuously conveyed in turn. Four card slots are equidistantly opened around the outer wall of the sleeve 602. The blade foot of the blade 603 is fixedly connected with a card block adapted to the card slot, and the card blocks are plugged and installed in each card slot one by one. The left and right ends of the ferrule 602 are fixedly connected with a rotating shaft, and the blade 603 is fixed by the engagement of the block and the slot, and can be directly removed by pulling, which is convenient for installation and disassembly, and is conducive to the maintenance and cleaning of the blade 603. The tool assembly also includes a steering motor 604; the rotating shaft at one end of the ferrule 602 is rotatably connected to the bracket 601 on one side, and the steering motor 604 is installed on the bracket 601 on the other side. The rotating shaft at the other end of the ferrule 602 is connected to the transmission shaft of the steering motor 604, and the steering motor 604 drives the ferrule 602 to rotate, and each rotation angle is ninety degrees, so that each tool is vertically downward to cut the patch package in turn. At the same time, by rolling the ferrule 602, the cut blade 603 is directed upward, and air is supplied through the air duct 4 to clean it.

[0038] See also Figure 6 In this embodiment, the positioning assembly includes a clamp 701, a sliding sleeve 702, and a sliding rod 703; the clamp 701 is sleeved on the air duct 4 and fixed by bolts, the lower end of the clamp 701 is fixedly connected to the sliding sleeve 702, the sliding sleeve 702 is inserted into the sliding rod 703, and a spring is installed between the sliding sleeve 702 and the sliding rod 703. The spring has the characteristic of elastic elongation and has an elastic pushing effect on the sliding rod 703 toward the outside of the sliding sleeve 702. The sliding rod 703 can also shrink into the sliding sleeve 702 after being compressed. The positioning assembly also includes a bracket 704 and a pressure roller 705; a U-shaped bracket 704 is welded and fixed to the lower end of the slide bar 703, and a pressure roller 705 is installed at the lower end of the vertical part of the bracket 704. The pressure roller 705 is made of hard rubber with anti-slip grooves on the surface. During the rotation and downward pressing process of the telescopic arm 3, the pressure roller 705 first contacts and rests on the patch package to press it tightly. The telescopic arm 3 continues to rotate to make the blade 603 press down and cut the patch package. At the same time, the pressure roller 705 is forced to push the slide bar 703 into the sleeve 702.

[0039] When working, the user connects the lower end of the support arm 1 to the motor drive shaft set on the frame of the patch packaging machine, and then starts the screw motor 8 to control the rotation of the screw according to the needs of cutting processing. The telescopic arm 3 uses the screw sleeve driven by the bottom of the telescopic arm 3 to extend and retract in and out of the slideway 2, so that the tool assembly is in a suitable position;

[0040] As the patch package is continuously conveyed on the workbench of the packaging machine, the motor on the packaging machine frame intermittently drives the support arm 1 to rotate, so that the cutter assembly is pressed down, and a blade 603 on the ferrule 602 gradually approaches the patch package, and the pressure roller 705 first contacts and abuts against the patch package to press it tightly, and the telescopic arm 3 continues to rotate to make the blade 603 press down and cut the patch package, and at the same time, the pressure roller 705 is pushed by the reverse force, and the spring is compressed and provides a continuous elastic thrust to the pressure roller 705;

[0041] After the cutting is completed, the arm 1 rotates to lift the cutter assembly, and then the steering motor 604 drives the ferrule 602 to rotate ninety degrees, and the other blade 603 is switched to face downward, and the operation continues in the above manner to continuously cut the dressing package;

[0042] During the cutting process, as the sleeve 602 continues to rotate and roll, the air duct 4 supplies air to each blade 603 to remove debris that may be adhered to its surface.

[0043] Through the above steps, the original straight-down cutting structure on the patch packaging machine is replaced with a rotating cutting structure, and the blade 603 is rolled and switched in conjunction with a tool assembly having multiple blades 603. During the cutting process, with the help of an external fan and an air duct 4, the blade 603 can be blown clean by wind after each cutting to remove chips, thereby avoiding the situation where the blade 603 cuts with chips and causes uneven cutting of the edge of the packaging material, so as to solve the problem that the packaging cutting structure of the existing patch packaging machine produces chips that are easily adhered to the tool during the cutting process, and the tool is easily lifted up with the packaged patch when it is lifted.

[0044] The embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings, but the present disclosure is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present disclosure.
