[0002] PE stretch wrap film, whose full name is polyethylene stretch wrap film, is a plastic film widely used in the packaging industry. It is mainly made of polyethylene as raw material and is made through extrusion, stretching and other processes. This film has good tensile properties and can be tightly wrapped around the surface of the packaged items, playing multiple roles such as protection, fixation and dust prevention. In the production process of PE stretch wrap film, heating and drying is an important link. Traditional heating and drying equipment has some shortcomings. For example, the area of the heated surface of PE stretch wrap film that receives drying heating during the transmission heating process is certain, and the contact time of each part with the heat outlet is certain. It is impossible to increase the heated area without affecting the heating efficiency. Therefore, the heating drying effect of PE stretch wrap film needs to be improved. Therefore, the present application proposes a heating and drying equipment that can adjust the size of the heated surface of PE stretch wrap film at the same time. Summary of the Invention

[0027] Example 1
[0028] like Figure 1-4 As shown, the utility model proposes a heating and drying device for PE stretch wrapping film, comprising a frame 1 and a drying cover 2 installed on the top of the frame 1. The drying cover 2 has two ports, namely a film inlet port and a film outlet port.
[0029] A protective plate assembly 8 is installed in the film inlet port, and a baffle 9 is installed in the film outlet port. Both the protective plate assembly 8 and the baffle 9 are located above the PE stretch wrap film.
[0030] Two sets of rollers 4 are provided below the frame 1. One side of each set of rollers 4 is equipped with a motor to drive the rotation thereof. One set is located below the frame 1 at the film inlet port and is used to tension and discharge the PE stretch film to be processed. The other set is located below the film outlet port and is used to wind up the PE stretch film after heating and drying.
[0031] The machine also includes a conveyor belt assembly 3 installed in the frame 1 for transporting PE stretch wrap film, a heating pipe 5 and an exhaust fan 6 installed on the top of the drying cover 2, the input end of the heating pipe 5 is further connected to the power supply main body 51 located on the top of the drying cover 2 via an electric wire, and the exhaust fan 6 is located above the center of the heating pipe 5;
[0032] like Figure 1-Figure 3 As shown, an exhaust plate assembly 7 located on the drying hood 2 is also provided below the heating tube 5. The exhaust plate assembly 7 includes two groups of wind shields 71. A rotating shaft 72 is fixedly installed inside the two groups of wind shields 71. The outer rings of the two groups of rotating shafts 72 pass through one end of the drying hood 2 and are fixedly sleeved with an arc plate 74. The outer arc surface arrays of the two groups of arc plates 74 are fixedly provided with a plurality of teeth. The two groups of arc plates 74 are driven by tooth meshing. A micro motor 73 is fixedly installed at one end of one group of rotating shafts 72.
[0033] In this embodiment, the PE stretch wrap film is stretched, heated and dried under the guidance of the conveyor belt assembly 3. The heat generated by the heating tube 5 is blown away by the exhaust fan 6, and the protection plate assembly 8 and the baffle 9 are combined to prevent the heat from escaping too quickly. At the same time, if the humidity of the PE stretch wrap film is high, the heating time needs to be increased. Therefore, the expansion angle of the wind shield 71 can be adjusted to expand the heat exhaust port and thus increase the contact time between the PE stretch wrap film and the hot air, thereby achieving the drying of the PE stretch wrap film. Specifically, by starting the micro motor 73, the output end of the micro motor 73 rotates the rotating shaft 72 and the arc plate 74, and at the same time, the other arc plate 74 engages with it, thereby achieving the synchronous relative rotation of the two groups of arc plates 74, and then the two groups of wind shields 71 are relatively carded, thereby achieving the purpose of expanding the heat outlet.
[0034] Example 2
[0035] like Figure 1-4 As shown, based on Example 1, the protective plate assembly 8 includes a protective plate body 81 rotatably mounted on the top of the film inlet port of the frame 1, and a mounting groove is provided at the bottom of the protective plate body 81. A rotating roller 82 is rotatably mounted in the mounting groove, and a cloth roller is detachably mounted on the outer ring of the rotating roller 82. Through the continuous transmission of the PE stretch wrap film and the setting of the rotating roller 82, the dust on the surface of the PE stretch wrap film will be wiped and cleaned, thereby improving the cleanliness of the PE stretch wrap film.
[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
