Description

Technical Field

[0001] The utility model relates to the technical field of splitting devices, in particular to a splitting device for POF film production. Background Art

[0002] POF film refers to polyethylene heat shrinkable film, which is a heat shrinkable film made of polyethylene material and is mainly used for packaging. POF film has excellent transparency, flexibility and tear resistance. It can shrink after being heated, wrap objects and tightly wrap their surfaces, thus playing the roles of protection, sealing and beautifying packaging. In the process of POF film production, a splitting device can accurately cut the POF film according to production requirements, making it have the required width and length, which can reduce waste and loss and maximize the utilization of raw materials. The splitting device plays a key role in POF film production, helping to ensure the accuracy, efficiency and quality of production, and also contributing to reducing production costs and improving resource utilization efficiency;

[0039] Refer to Figures 1 - 3 , an embodiment provided by the present invention: A cutting device for POF film production, including:

[0043] The motor 10, the motor 10 is fixedly connected to one side of the operating table 1, the output end of the motor 10 is fixedly connected with a rotating column 11, the rotating column 11 and the limit post 7 are symmetrically arranged up and down, and the rotating column 11 and the limit post 7 are used to drive the POF film to move;

[0044] The fixed post 8, the fixed post 8 is fixedly connected to the inside of the second support frame 6 and the first support frame 4, a first spring 9 is sleeved on the outer wall of the fixed post 8, the top end of the first spring 9 is fixedly connected to the outer wall of the fixed post 8, and the bottom end of the first spring 9 is fixedly connected to the outer wall of the limit post 7. The first spring 9 is used to apply pressure to the limit post 7. A cutting device for POF film production, characterized in that: including:

[0045] Operating table 1, a fixed frame 2 is fixedly connected to the top of the operating table 1, a winding drum 3 is rotatably connected inside the fixed frame 2, the winding drum 3 is used to support the POF film, and a cutting assembly is arranged on the top of the operating table 1, and the cutting assembly is used to divide the POF film;

[0046] First support frame 4, the first support frame 4 is fixedly connected to the top of the operating table 1 symmetrically front and back, a guiding column 5 is rotatably connected inside the first support frame 4, and the guiding column 5 is used to guide the POF film;

[0047] Second support frame 6, the second support frame 6 is fixedly connected to the top of the operating table 1 symmetrically front and back, and a limiting column 7 is rotatably connected inside the second support frame 6;

[0048] Motor 10, the motor 10 is fixedly connected to one side of the operating table 1, a rotating column 11 is fixedly connected to the output end of the motor 10, the rotating column 11 and the limiting column 7 are symmetrically up and down, and the rotating column 11 and the limiting column 7 are used to drive the POF film to move;

[0049] Fixed column 8, the fixed column 8 is fixedly connected inside the second support frame 6 and the first support frame 4, a first spring 9 is sleeved on the outer wall of the fixed column 8, the top end of the first spring 9 is fixedly connected to the outer wall of the fixed column 8, and the bottom end of the first spring 9 is fixedly connected to the outer wall of the limiting column 7. The first spring 9 is used to apply pressure to the limiting column 7.

[0050] Specifically, when using this POF film dividing device, first wind the POF film around the outer wall of the winding drum 3. Subsequently, pass one side of the POF film through the gap between the rotating column 11 and the limiting column 7. The limiting column 7 plays a key role in this process. It not only contacts the POF film but also bears the force from the film material. When the POF film contacts the limiting column 7, the limiting column 7 slides inside the second support frame 6. This sliding action enables the limiting column 7 to flexibly adjust and limit according to the position of the POF film. At the same time, the limiting column 7 also squeezes the first spring 9 connected to its outer wall by force. The function of the first spring 9 is to contract inward after being acted upon by the force of the limiting column 7 and then rebound by unloading the force of the first spring 9 in the subsequent process. This process not only helps the limiting column 7 to closely fit above the POF film to effectively limit the film material but also ensures the stability and reliability of the limiting column 7, ensuring that the limiting column 7 can accurately perform its limiting function during operation.

[0051] Refer to Figure 1 and Figure 4 As shown in [relevant figure numbers], the cutting assembly includes a connecting frame 13, the connecting frame 13 is fixedly connected to the top of the operating table 1, a cylinder 14 is fixedly connected to the top of the connecting frame 13, a pressing block 15 is fixedly connected to the output end of the cylinder 14, a mounting seat 16 is slidably connected inside the pressing block 15, and a cutting knife 17 is fixedly connected inside the mounting seat 16.

[0052] Specifically, when operating the POF film splitting device, the output end of the motor 10 drives the rotating column 11 to rotate. This action enables the rotating column 11 to drive the POF film to move on the device. The function of the rotating column 11 is to ensure the smooth movement and position adjustment of the film so that the subsequent splitting operation can be carried out precisely. When the POF film moves below the connecting frame 13, the output end of the cylinder 14 starts to work. The cylinder 14 drives the pressing block 15 to move through the output end. The movement of the pressing block 15 causes it to be stressed and drives the internal mounting seat 16 to move accordingly. After the mounting seat 16 is stressed, it drives the internally connected cutting knife 17 to move. The cutting knife 17 is a key component of the splitting device, and its movement directly cuts and splits the POF film, thus realizing the main function of the splitting device.

[0053] Refer to Figure 5 and Figure 6 , a limiting frame 12 is fixedly connected to the top of the operating table 1. A positioning pin 18 is fixedly connected inside the mounting seat 16. A hollow column 19 is fixedly connected inside the pressing block 15. The positioning pin 18 is slidably connected inside the hollow column 19. A second spring 20 is arranged inside the hollow column 19. One end of the second spring 20 is fixedly connected to a ball 21. The ball 21 is slidably connected inside the positioning pin 18. A support column 22 is fixedly connected inside the positioning pin 18. The outer wall of the support column 22 is slidably connected to a tapered head 24. A third spring 23 is sleeved on the outer wall of the support column 22. The top end of the third spring 23 is fixedly connected to the bottom end of the tapered head 24. The bottom end of the third spring 23 is fixedly connected inside the positioning pin 18.

[0054] Specifically, when disassembling, installing and maintaining the cutting knife 17, first, the mounting seat 16 on the outer wall of the cutting knife 17 needs to be inserted into the pressing block 15 to ensure that the cutting knife 17 can be accurately positioned and fixed in the correct position. At the same time, the positioning pin 18 inside the mounting seat 16 will slide into the hollow column 19 inside the pressing block 15. This action of the positioning pin 18 ensures the stable connection between the mounting seat 16 and the pressing block 15, providing the necessary support and positioning for subsequent disassembly and installation. After the tapered head 24 inside the positioning pin 18 contacts the hollow column 19, the tapered head 24 can slide into the positioning pin 18. After the tapered head 24 is stressed, it will squeeze the third spring 23 connected to the bottom end, causing it to contract, ensuring that the positioning pin 18 can smoothly enter the hollow column 19. At the same time, the insertion of the positioning pin 18 will squeeze the ball 21 inside the hollow column 19, and then squeeze the second spring 20 to contract. The function of the second spring 20 is to provide pressure after installation to ensure that the ball 21 can accurately snap into the groove on the outer wall of the positioning pin 18 to firmly fix the position of the cutting knife 17, ensuring the convenient disassembly, installation and maintenance of the cutting knife 17, and effectively improving the maintenance efficiency and operation convenience of the equipment.

[0055] Working principle: When using this POF film splitting device, first wind the POF film around the outer wall of the reel 3, and pass one side of the POF film through between the rotating column 11 and the limiting column 7. When the POF film contacts the limiting column 7, the limiting column 7 will be forced to slide inside the support frame two 6. At the same time, the limiting column 7 will forcefully squeeze the first spring 9 connected to the outer wall, causing it to contract inside the support frame two 6. Then, through the elastic return of the first spring 9, the limiting column 7 is driven to tightly fit above the POF film, achieving the effect of effectively limiting the POF film. At this time, the rotating column 11 is driven to rotate by the output end of the motor 10, so that the rotating column 11 drives the POF film to move. When the POF film moves below the connecting frame 13, the pressing block 15 is driven to move by the output end of the cylinder 14. The pressing block 15 drives the mounting seat 16 inside it to move under force. The mounting seat 16 drives the cutting knife 17 connected inside it to move under force. Through the movement of the cutting knife 17, the POF film is cut and split. When it is necessary to disassemble, install and maintain the cutting knife 17, first insert the mounting seat 16 on the outer wall of the cutting knife 17 into the pressing block 15. In this process, the positioning pin 18 inside the mounting seat 16 will slide into the hollow column 19 inside the pressing block 15. At the same time, the tapered head 24 inside the positioning pin 18 will contact the hollow column 19, causing the tapered head 24 to slide into the positioning pin 18. The tapered head 24 forces the third spring 23 connected to the bottom end to be squeezed, causing it to contract, so that the positioning pin 18 smoothly slides into the hollow column 19. At the same time, the positioning pin 18 will squeeze the ball 21 inside the hollow column 19, and the ball 21 forces the second spring 20 to contract under force. When the positioning pin 18 slides into a certain position, through the elastic return of the second spring 20, the ball 21 is pushed to snap into the groove on the outer wall of the positioning pin 18 to fix it, thus achieving the effect of facilitating the disassembly, installation and maintenance of the cutting knife 17.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
