This single-sided drying design may cause problems such as adhesive seepage and ink shedding on the undried side, affecting the quality and appearance of the plastic packaging film. Therefore, a plastic packaging film drying device that can heat and dry both sides simultaneously is needed. Utility Model Content

[0005] The technical solution of the utility model is aimed at the existing technology that solves too single technical problems, and provides a solution that is significantly different from the existing technology. In order to overcome the above defects of the existing technology, the utility model provides a new solution to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plastic packaging film drying device, comprising a base, on which a drying bracket, a transition bracket and a winding bracket are installed in sequence, and a drying roller is rotatably connected to the drying bracket, one end of the drying roller passes through the drying bracket to be connected to the first motor output end on the outside, and the other end of the drying roller also passes through the drying bracket to be connected to the steam rotary joint on the outside, a steam pipe is provided inside the steam rotary joint, the steam pipe is connected to the heating chamber inside the drying roller, and the port of the steam pipe is connected to the output end of the steam boiler, and a plurality of hot air blowers arranged equidistantly are provided on the base.

[0007] Optionally, a waste liquid channel is further provided on the side of the steam rotary joint away from the steam pipe, and a waste liquid pipe is installed inside the heating chamber. The waste liquid pipe extends downward from the steam rotary joint through the waste liquid channel.

[0008] Optionally, a mounting frame is provided on the drying bracket below the steam rotary joint, and the steam rotary joint is fixed on the mounting frame.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, a continuous and stable steam supply is provided to the steam pipeline through a steam boiler, and the steam is transported to the heating chamber of the drying roller, thereby ensuring uniform heating inside the drying roller, so that the drying roller has the function of heating the upper layer of the plastic packaging film and significantly improving the drying effect. In addition, the efficient drive of the first motor enables the drying roller to smoothly transport the plastic packaging film. When the plastic film is transported to the rear winding roller, a large number of equidistantly arranged hot air blowers configured on the base heat the upper plastic packaging film synchronously, thereby ensuring that the upper and lower layers of the plastic packaging film can be fully heated.

[0014] 2. In the utility model, the steam rotary joint transfers high-temperature steam to the heating chamber inside the drying roller. During the heat exchange process, the steam gradually cools down and condenses into condensed water. Since the steam pressure inside the heating chamber is higher than that of the external environment, under the action of the pressure difference, the condensed water is squeezed out of the heating chamber and discharged through the waste liquid pipe and the waste liquid channel, thereby realizing the circulation and removal of waste liquid, ensuring the cleanliness and normal operation of the inside of the heating chamber.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a plastic packaging film drying device, comprising a base 1, on which a drying bracket 2, a transition bracket 3 and a winding bracket 4 are sequentially mounted, a drying roller 7 is rotatably connected to the drying bracket 2, one end of the drying roller 7 passes through the drying bracket 2 to connect to the output end of the first motor 5 on the outside, and the other end of the drying roller 7 also passes through the drying bracket 2 to connect to the steam rotary joint 12 on the outside, a steam pipe 14 is provided inside the steam rotary joint 12, the steam pipe 14 is connected to the heating chamber 15 inside the drying roller 7, and the port of the steam pipe 14 is connected to the output end of the steam boiler, and a plurality of equidistantly arranged hot air blowers 18 are provided on the base 1.

[0023] In this embodiment, a steam boiler is used to provide a continuous and stable steam supply to the steam pipe 14, and the steam is transported to the heating chamber 15 of the drying roller 7, ensuring uniform heating inside the chamber 15, so that the drying roller 7 has the function of heating the upper layer of the plastic packaging film and significantly improving the drying effect. In addition, the efficient drive of the first motor 5 enables the drying roller 7 to smoothly transport the plastic packaging film. When the plastic film is transported to the rear winding roller 9, a large number of equidistantly arranged hot air blowers 18 configured on the base 1 simultaneously heat the upper plastic packaging film to ensure that the upper and lower layers of the plastic packaging film can be fully heated, thereby significantly improving the quality and appearance of the plastic packaging film and greatly meeting the high standards of production and process.

[0024] A waste liquid channel 17 is also provided on the side of the steam rotary joint 12 away from the steam pipe 14. A waste liquid pipe 16 is installed inside the heating chamber 15. The waste liquid pipe 16 extends downward from the steam rotary joint 12 through the waste liquid channel 17. A mounting frame 11 is provided on the drying bracket 2 below the steam rotary joint 12, and the steam rotary joint 12 is fixed on the mounting frame 11.

[0025] In this embodiment, the steam rotary joint 12 transfers high-temperature steam to the heating chamber 15 inside the drying roller 7. During the heat exchange process, the steam gradually cools down and condenses into condensed water. Since the steam pressure inside the heating chamber 15 is higher than the external environment, under the action of the pressure difference, the condensed water is squeezed out of the heating chamber 15 and discharged through the waste liquid pipe 16 and the waste liquid channel 17, thereby realizing the circulation and discharge of waste liquid, ensuring the cleanliness and normal operation of the heating chamber 15. In addition, this automatic drainage design simplifies the operating process, reduces the frequency of manual maintenance, and reduces the manpower and material resources generated thereby.

[0026] A film guide plate 10 is provided at the lower side of the drying roller 7 , a winding roller 9 is rotatably connected to the winding bracket 4 , the winding roller 9 passes through the winding bracket 4 and is connected to the output end of the second motor 6 on the outside, and a transition roller 8 is rotatably connected to the transition bracket 3 .

[0027] In this embodiment, the film guide plate 10 mainly guides and positions the plastic packaging film to ensure that it remains flat and stable during the transmission process to avoid wrinkles, twisting or deviation problems. The plastic packaging film is transported backward from the gap between the drying roller 7 and the film guide plate 10 to the transition roller 8. At the same time, the second motor 6 drives the winding roller 9 to rotate, so that the winding roller 9 can continuously wind up the plastic packaging film, thereby improving the degree of automation of the device and reducing the degree of manual winding.

[0028] The drying support 2 , the transition support 3 and the winding support 4 are all embedded with bearings 13 , and the drying roller 7 , the transition roller 8 and the winding roller 9 are rotatably connected in the corresponding bearings 13 .

[0029] In this embodiment, the bearing 13 plays a role in supporting and fixing the drying roller 7 , the transition roller 8 and the winding roller 9 .

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
