[0033] The following further describes the present utility model in detail through specific embodiments in conjunction with the accompanying drawings.

[0034] Referring to Figures 1 to 3 , the printing and drying machine provided in this embodiment includes a machine body 100, a hot air mechanism 200, and a reflux assembly 300.

[0035] Among them, the machine body 100 has a drying tank 110, and a reflux cavity 120 is provided at the bottom of the drying tank 110. The hot air mechanism 200 is arranged in the drying tank 110 and is located at one end of the drying tank 110. The reflux assembly 300 is arranged at the other end of the drying tank 110. The air inlet of the reflux assembly 300 is arranged in the drying tank 110, and the air outlet of the reflux assembly 300 is arranged in the reflux cavity 120 and faces the hot air mechanism 200.

[0036] Moreover, the air outlet of the hot air mechanism 200 faces the end of the drying tank 110 where the reflux assembly 300 is arranged and is inclined towards the tank opening of the drying tank 110, and the hot air mechanism 200 is communicated with the reflux cavity 120.

[0037] During use, the tank opening of the drying tank 110 is oriented and close to the material to be dried. Subsequently, the printing and drying machine is operated to enable the hot air mechanism 200 to generate heat and hot air. The hot air flows through the drying tank 110 and then towards the material to be dried, thereby realizing the drying of the patterns and contents on the surface of the material to be dried.

[0038] During the drying process, the hot air mechanism 200 generates hot air and discharges it to the surface of the material. After the dried hot air contacts the surface of the material, it moves towards the reflux assembly 300 together with the remaining hot air in the drying tank 110 between the material and the drying tank 110.

[0039] After the hot air reaches the reflux assembly 300, it is inhaled by the reflux assembly 300 and discharged into the reflux cavity 120 to flow towards the hot air mechanism 200. The air flow generated by the hot air mechanism 200 is mixed with the hot air with heat in the reflux cavity 120 and then reheated and discharged for drying, thereby realizing the reuse of the lost and remaining hot air, reducing the loss and emission of hot air, and thus avoiding heat loss and reducing energy waste.

[0040] In this embodiment, an installation part is provided at one end of the drying tank 110. A mixing tank 130 is provided at one end of the installation part close to the reflux assembly 300. The bottom of the mixing tank 130 is communicated with the reflux cavity 120. The tank opening of the mixing tank 130 faces the end of the drying tank 110 where the reflux assembly 300 is arranged and is inclined towards the tank opening of the drying tank 110. The bottom surface of the installation part is an inclined surface, and the hot air mechanism 200 is arranged on the installation part.

[0041] The installation part is used to install the hot air mechanism 200. The hot air mechanism 200 introduces the reflux hot air in the mixing tank 130 into the mixing tank 130 for heating together. The hot air in the mixing tank 130 is discharged to the drying tank 110 for drying after being reheated.

[0042] Among them, the bottom surface of the installation part in this embodiment is an inclined surface structure. The bottom surface of the inclined surface structure can make the air outlet of the hot air mechanism 200 face the end of the drying tank 110 where the reflux component 300 is provided and incline towards the notch of the drying tank 110. In this state, the hot air generated by the hot air mechanism 200 can quickly contact the material to be dried at the notch, avoiding heat loss caused by too large a distance.

[0043] In this embodiment, the hot air mechanism 200 includes a fan 210 and a heating element 220. The fan 210 is arranged on the installation part, and the air outlet of the fan 210 faces the mixing tank 130. The heating element 220 is arranged at the air outlet of the fan 210.

[0044] The fan 210 can generate an air flow, generating an air flow flowing towards the reflux component 300. After the fan 210 generates the air flow, it is discharged into the mixing tank 130. The air flow is mixed with the hot air in the reflux chamber 120, and the heating element 220 heats the mixed gas, thereby realizing the utilization of the heat in the reflux air flow. After the air flow temperature rises, it contacts the material to be dried to realize drying.

[0045] Among them, specifically, the fan 210 in this embodiment is an axial flow fan 210. The axial flow fan 210 has good cooling effect and low energy consumption. In addition, the ventilation timing of the axial flow fan 210 is easy to master, and it is not easy to condense. When in use, there is no need to separately equip the fan 210, which is convenient and flexible.

[0046] And, the heating element 220 in this embodiment is a heating module. The heating element base material of the heating module is carbon fiber felt and carbon fiber wire, which has a long service life and high electrothermal conversion efficiency.

[0047] In this embodiment, the machine body 100 includes a main body 140 and an extension section 150. The main body 140 is detachably connected to the extension section 150. The hot air mechanism 200 is arranged at one end of the main body 140 away from the extension section 150. The reflux component 300 is arranged at one end of the extension section 150 away from the main body 140.

[0048] Specifically, the machine body 100 in this embodiment is a combined structure. The extension section 150 can effectively lengthen the drying distance and area, so as to realize the drying of materials with different sizes and specifications.

[0049] In this embodiment, the printing and drying machine further includes an auxiliary heating component 400. The auxiliary heating component 400 is arranged in the drying tank 110 and is located in the extension section 150.

[0050] The auxiliary heating element 220 can be heated up for auxiliary heating, preventing excessive heat loss in the hot air at the extension section 150 and enabling uniform drying to be achieved.

[0051] Among them, the auxiliary heating assembly 400 includes a plurality of heating tubes. The plurality of heating tubes are evenly arranged in the drying tank 110.

[0052] The heating tubes have high thermal efficiency and uniform heat generation. In this embodiment, the plurality of heating tubes are evenly arranged in the drying tank 110 to ensure uniform drying.

[0053] In this embodiment, the printing and drying machine further includes a temperature measuring element 500. The temperature measuring element 500 is arranged in the drying tank 110 and located in the main body 140. The temperature measuring element 500 is used to measure the outlet air temperature of the hot air mechanism 200.

[0054] The temperature measuring document can measure the temperature of the hot air discharged by the hot air mechanism 200, so as to judge whether the outlet air temperature can achieve complete drying of the material to be dried, and can adjust the temperature of the heating tubes according to the detected temperature.

[0055] In this embodiment, the height of the drying tank 110 gradually narrows from the main body 140 to the extension section 150. The width of the return cavity 120 is smaller than the width of the drying tank 110.

[0056] The height of one end of the drying tank 110 close to the hot air mechanism 200 is larger. The height of the drying tank 110 in the extension section 150 is smaller than the height of the drying tank 110 in the main body 140. In this structure, the flow rate of the hot air for drying can be enhanced, and a relatively large vertical space can be provided for installing the hot air mechanism 200.

[0057] Moreover, the width of the return cavity 120 is smaller, which can also increase the flow rate of the air flow in the return cavity 120 and prevent excessive heat loss of the air flow during the return process.

[0058] In this embodiment, the printing and drying machine further includes movable feet. There are a plurality of movable feet, and the plurality of movable feet are evenly arranged at the bottoms of the main body 140 and the extension section 150.

[0059] The movable feet can facilitate the movement of the printing and drying machine for position adjustment or transfer, and can support the machine body 100.

[0060] The printing equipment provided in this embodiment includes the provided printing and drying machine.

[0061] After the printing of the material is completed, the material is dried by a printing and drying machine. The notch of the drying tank 110 is oriented towards and close to the material to be dried. During the drying process, the hot air mechanism 200 generates hot air and discharges it onto the surface of the material. After the dried hot air contacts the surface of the material, it moves towards the reflux assembly 300 together with the remaining hot air in the drying tank 110 between the material and the drying tank 110. After the hot air reaches the reflux assembly 300, it is sucked in by the reflux assembly 300 and discharged into the reflux chamber 120 to flow towards the hot air mechanism 200. The hot air generated by the hot air mechanism 200 is mixed with the hot air with heat in the reflux chamber 120 and then discharged for drying, thereby realizing the reuse of the lost and remaining hot air, reducing the loss and emission of hot air, and thus avoiding heat loss and reducing energy waste.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
