DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0019] See also Figure 1-3 The utility model provides a technical solution: a shrink packaging machine for processing heat shrink film, comprising an equipment box 1 with an open top, a first conveyor belt 2 and a second conveyor belt 3 are transversely arranged at the rear and front of the upper end of the equipment box 1, respectively, and a transverse plate 4 is transversely fixedly connected between the two side walls of the equipment box 1 and between the first conveyor belt 2 and the second conveyor belt 3;
[0020] The inner surfaces of the two side walls of the equipment box 1 and located directly above the cross plate 4 are fixedly connected with a fixing seat 6, the upper surfaces of the two fixing seats 6 are vertically fixedly connected with guide rods 7, the top ends of the multiple guide rods 7 are horizontally fixedly connected with a top plate 8, the outer surfaces of the multiple guide rods 7 are vertically slidably connected with sliding seats 9, and slitting knives 10 are horizontally fixedly connected between the multiple sliding seats 9. The two side surfaces of the slitting knife 10 are vertically slidably connected with lower pressing plates 13 matched with the length thereof, and the outer sides of the two lower pressing plates 13 are fixedly connected with electric heating wires 16.
[0021] The top end of the slitting knife 10 is fixedly connected to a receiving seat 11 along its length direction, and a plurality of electrically controlled telescopic rods 12 are vertically fixedly connected between the top plate 8 and the receiving seat 11 .
[0022] In this embodiment, the device is provided with lower pressing plates 13 on both sides of the slitting knife 10. When the heat shrink film is cut, the electric telescopic rod 12 drives the slitting knife 10 to move downward, and the two lower pressing plates 13 will first contact the heat shrink film. The outer surfaces of the two lower pressing plates 13 are provided with electric heating wires 16, which can heat the lower pressing plates 13, so that the heat shrink film is heated and shrunk first, and then the slitting blade 10 cuts the heat shrink film from between the two lower pressing plates 13, thereby improving the cutting effect and preventing the heat shrink film from still sticking after cutting, thereby improving the final packaging effect and improving the practicality of the device.
[0023] Furthermore, the top ends of the two lower pressure plates 13 are vertically fixedly connected with multiple guide rods 14, the top ends of the multiple guide rods 14 can slidably pass through the receiving seat 11 and extend upward, the outer surfaces of the multiple guide rods 14 and located between the lower pressure plate 13 and the receiving seat 11 are all provided with springs 15, and the top and bottom ends of the multiple springs 15 are respectively fixedly connected to the lower surface of the receiving seat 11 and the upper surface of the lower pressure plate 13.
[0024] A groove 5 is formed on the upper surface of the transverse plate 4 along its length.
[0025] In this embodiment, when the electrically-controlled telescopic rod 12 drives the receiving seat 11 and the slitting knife 10 to move downward, the two lower pressing plates 13 will first contact the heat shrink film, and then drive the heat shrink film to move downward until it contacts the upper surface of the horizontal plate 4. At this time, the heat shrink film will be tightly fitted with the lower pressing plates 13, so that the heat of the lower pressing plates 13 can be completely transferred to the heat shrink film, thereby pressing and sealing the upper and lower heat shrink films. Then the slitting knife 10 will continue to move downward to completely cut off the heat shrink film in the groove 5. During this process, under the action of the spring 15, the two lower pressing plates 13 will always be close to the heat shrink film, limiting it to prevent it from sliding, thereby ensuring the cutting effect.
[0026] The guide rod 14 can guide the lower pressing piece 13 to prevent it from being skewed.
[0027] Furthermore, a lower discharge roller 17 and a first guide roller 18 are provided inside the equipment box 1 and below the second conveyor belt 3, and a mounting frame 19 is vertically fixedly connected to the top of the two side walls of the equipment box 1 and above the first conveyor belt 2, and an upper discharge roller 20 and a second guide roller 21 are provided inside the mounting frame 19.

The upper discharge roller 20 is provided with an upper heat shrink film roller, which is guided by the second guide roller 21 and extends to the top of the second conveyor belt 3. When both are moved by the product, both sides of the two will be pressed and sealed by the edge pressing device 22, so as to ensure the sealing performance of the final packaging.
[0030] The support pad 23 plays a supporting role.
[0031] The working principle and use process of the utility model: after the utility model is installed, the device is provided with lower pressing plates 13 on both sides of the slitting knife 10. When the heat shrink film is cut, the electric telescopic rod 12 drives the slitting knife 10 to move downward, and the two lower pressing plates 13 will first contact the heat shrink film. The outer surfaces of the two lower pressing plates 13 are provided with electric heating wires 16, which can heat the lower pressing plates 13, so that the heat shrink film is heated and shrunk first, and then the slitting blade 10 cuts the heat shrink film from between the two lower pressing plates 13, thereby improving the cutting effect and preventing the heat shrink film from still sticking after cutting, thereby improving the final packaging effect and improving the practicality of the device.
