Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0030] As Figures 1 to 3 shown, this embodiment proposes a drying device for producing kraft paper bags, including

[0031] a box body 1 and a transverse hole 2, and the transverse hole 2 is opened on both side surfaces of the box body 1;

[0033] a hot drying assembly 4, and the hot drying assembly 4 is arranged inside the box body 1;

[0034] a cooling and shaping assembly 6, and the cooling and shaping assembly 6 is arranged outside the side plates 3;

[0035] The hot drying component 4 includes a pair of infrared heat lamps 4-1, which are installed at the upper and lower ends inside the box body 1. Air inlets 4-2 are provided at the top and bottom of the box body 1. Intake pipes 4-3 are connected to the top and bottom of the box body 1. A first fan 4-4 is installed at one end of the intake pipe 4-3. A pair of glass plates 4-5 are arranged inside the box body 1. Inner covers 4-6 are connected between the two sides of the glass plates 4-5 and the box body 1. Ventilation mesh holes 4-7 are formed on the surfaces of the inner covers 4-6.

[0036] In this embodiment, in order to achieve the effect of double-sided drying of kraft paper, the hot drying component 4 is designed. Two infrared heat lamps 4-1 are arranged inside the box body 1, and the heat for drying is emitted through infrared radiation. Two glass plates 4-5 and inner covers 4-6 are arranged inside. The inner covers 4-6 are connected between the glass plates 4-5 and the inner wall of the box body 1. The glass plates 4-5 can diffuse the irradiation of the infrared heat lamps 4-1 and generate heat around. Intake pipes 4-3 are provided at the top and bottom of the box body 1. A first fan 4-4 is installed at one end of the intake pipe 4-3, and external air can be blown into the box body 1 through the intake pipe 4-3 and the air inlets 4-2. Ventilation mesh holes 4-7 are formed on the surfaces of the inner covers 4-6, and the air entering blows the heat around the infrared heat lamps 4-1 into the inner covers 4-6 and then evenly covers the surface of the kraft paper through the ventilation mesh holes 4-7.

[0037] Furthermore, the conveying component 5 includes a pair of inlet rollers 5-1, which are rotatably connected between the side plates 3. A pair of discharge rollers 5-2 are rotatably connected between the side plates 3 on the other side. Transmission gears 5-3 are provided at one ends of the inlet rollers 5-1 and the discharge rollers 5-2. Transmission wheels 5-4 are provided at one ends of the inlet rollers 5-1 and the discharge rollers 5-2. The transmission wheels 5-4 are connected by a belt drive. An outer frame 5-5 is arranged on the side surface of the box body 1. A drive motor 5-6 is installed on the surface of the outer frame 5-5. The output end of the drive motor 5-6 is connected to the discharge roller 5-2.

[0038] In this embodiment, in order to achieve the effect of conveying kraft paper in a tensioned state, a conveying component 5 is designed. Two inlet rollers 5-1 and two outlet rollers 5-2 are respectively arranged between two groups of side plates 3 on both sides of the box body 1 for clamping and conveying kraft paper. Transmission gears 5-3 are arranged at one ends of the inlet rollers 5-1 and the outlet rollers 5-2. Transmission wheels 5-4 are arranged at one ends of one of the inlet rollers 5-1 and one of the outlet rollers 5-2. The transmission wheels 5-4 are connected by belt drive. An outer frame 5-5 is arranged on the outer surface of the box body 1 and a drive motor 5-6 is installed. The output end of the drive motor 5-6 is connected to the outlet roller 5-2, so that the inlet roller 5-1 and the outlet roller 5-2 can rotate synchronously to achieve the conveying effect.

[0039] Further, the cooling and shaping component 6 includes a pair of external connection plates 6-1. Cooling fans 6-2 are installed on the surfaces of the external connection plates 6-1. A plurality of shaping rollers 6-3 are rotatably connected between the external connection plates 6-1.

[0040] In this embodiment, in order to achieve the effect of keeping the dried paper flat, a cooling and shaping component 6 is designed. Two external connection plates 6-1 are arranged at the outlet end. A plurality of shaping rollers 6-3 are connected between the external connection plates 6-1. The kraft paper passes over the surface of the first shaping roller 6-3, bypasses the bottom of the lower shaping roller 6-3, and then bypasses the top of the outermost shaping roller 6-3 and is connected to the winding device, which can increase the tension to flatten the kraft paper. Cooling fans 6-2 are installed in the external connection plates 6-1, and the cooling fans 6-2 continuously blow air on the kraft paper for cooling.

[0041] Further, a cross bar 7 is connected between the side plates 3, and a perforation 8 is formed on the side end face of the cross bar 7.

[0042] In this embodiment, by installing the cross bar 7 and opening the perforation 8 with the same thickness as the kraft paper, the flat state of the kraft paper during conveying is improved.

[0043] Further, the glass plate 4-5 is made of a heat non-blocking material. The glass plate 4-5 is integrally in an arc structure. The infrared heat lamp 4-1 is located at the middle position of the glass plate 4-5.

[0044] In this embodiment, due to the heat non-blocking material, the glass plate 4-5 can generate temperature through light transmission to dry the kraft paper, and the temperature diffuses to the surrounding through the arc structure. With the arc structure of the glass plate 4-5, it is convenient to diffuse the surrounding temperature outward.

[0045] Further, the distance between the inner covers 4-6 is the same as the opening size of the horizontal holes 2.

[0046] In this embodiment, by making the distance between the inner covers 4-6 the same as that of the horizontal holes 2, the kraft paper entering can better contact the hot air.

[0047] Further, several of the shaping rollers 6-3 are distributed at the points in a triangular structure.

[0048] In this embodiment, through the effect of the triangular point distribution, the tensioning effect of the kraft paper can be better.

[0049] Further, the intake pipe 4-3 is of a tee structure and is simultaneously connected to the air inlets 4-2 at the top and bottom of the box body 1.

[0050] In this embodiment, through the intake pipe 4-3 of the tee structure, a single intake fan can blow into the top and bottom of the box body 1 at the same time.

[0051] When drying is required, the kraft paper passes through the perforations 8 and the transverse holes 2, then the kraft paper is wound around a plurality of shaping rollers 6-3 and connected to the winding device. The driving motor 5-6 is started to make the inlet roller 5-1 and the discharge roller 5-2 start to rotate simultaneously, and the kraft paper is conveyed at a constant speed. During the conveying process, the infrared heat lamp 4-1 and the intake fan are started. The infrared heat lamp 4-1 directly irradiates the kraft paper through the glass plate 4-5. At the same time, the gas entering covers the surface of the kraft paper with the temperature around the infrared heat lamp 4-1 through the ventilation mesh holes 4-7 to achieve the drying effect, and the cooling fan 6-2 is started to quickly cool the dried kraft paper back to the normal state.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
