Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, a drying device provided by the utility model includes an infrared emitting component 100 and a hot air channel 200. The infrared emitting component 100 is provided with an infrared emitting tube 110 and a first cooling chamber 120 arranged along the extension direction of the infrared emitting tube 110. A first air inlet 130 is arranged on one side of the first cooling chamber 120. An emitting part is arranged at the bottom of the infrared emitting tube 110. The emitting part is arranged toward the parts to be dried so as to emit infrared light to the parts to be dried. Two hot air channels 200 are respectively arranged on both sides of the infrared emitting component 100 along the extension direction of the infrared emitting component 100 and are connected to the infrared emitting component 100. The hot air channel 200 is connected to a hot air source. A wind nozzle 210 is arranged at the bottom of the hot air channel 200. The wind nozzle 210 is arranged toward the parts to be dried. The two hot air channels are arranged opposite to each other.

[0030] That is, the drying device provided by the utility model emits infrared light to the parts to be dried through the infrared emitting tube 110 in the infrared emitting assembly 100, and blows hot air to the parts to be dried through the hot air channel 200. The two are mixed and dried to ensure the uniformity of drying and heating of the parts to be dried, which solves the technical problem in the prior art that the heating and drying effect of infrared lamp tube irradiation and heating is concentrated, which easily leads to uneven drying effect of the coating equipment and a high risk of damage to the coating equipment.

[0031] Specifically, the infrared emitting tube 110 is set as an infrared lamp tube, and its model can be a single-tube infrared lamp tube or an infrared tube, which is straight and long as a whole. An emitting part is arranged at the bottom of the infrared emitting tube 110, and the emitting part is arranged toward the part to be dried to emit infrared light to the part to be dried. The first cooling chamber 120 is arranged along the extension direction of the infrared emitting tube 110, and a first air inlet 130 is arranged at one end of the first cooling chamber 120, and the first air inlet 130 is connected to an external cold air source. In this way, the infrared emitting tube 110 can be cooled through the first cooling chamber 120. The hot air channel 200 is fixed to both sides of the infrared emitting assembly 100 by bolts or welding, and is connected to the outer wall of the first shell 150. The top of the hot air channel 200 is connected to the external hot air source, and the air nozzle 210 of the hot air channel 200 is arranged at the bottom of the hot air channel 200, and the two air nozzles 210 are arranged downward toward the part to be dried. In this way, hot air can be blown to the parts to be dried through the hot air channel 200. Since the hot air flow continues to flow on the top of the parts to be dried, the heat exchange between the parts to be dried and the hot air flow on the top will be accelerated, so that the temperature of the parts to be dried rises evenly, ensuring the uniformity of drying and heating of the parts to be dried, and further improving the drying efficiency of the drying device. In this embodiment, the two air nozzles 210 are arranged opposite to each other and at 45 degrees to the vertical direction, and the parts to be dried are arranged directly below the infrared emitting assembly 100. In this way, the two air nozzles 210 can blow hot air toward the parts to be dried at the same time.

[0032] Furthermore, the infrared emitting assembly 100 further includes a flow guide cover 140 , which is arranged along the extending direction of the infrared emitting tube 110 , and the bottom of the flow guide cover 140 is opened, and the infrared emitting tube 110 is arranged in the flow guide cover 140 .

[0033] Specifically, the air deflector 140 is in the shape of an elongated strip as a whole, and its cross section is approximately U-shaped, and its opening is set downward. The direction in which the air deflector 140 is set is the same as the extension direction of the infrared emitting tube 110, so that the air deflector 140 is conveniently set above the infrared emitting tube 110, so that the side surface of the air deflector 140 close to the infrared emitting tube 110 becomes a reflective surface. The air deflector 140 as a whole can be made of plastic material or metal material by integral injection molding, or it can be made of two symmetrically arranged air deflector 140 plates fixed and spliced ​​by bolts. In this embodiment, the material of the air deflector 140 is set to aluminum profile, and its reflective surface is polished to increase the infrared reflectivity of the air deflector 140. The reflective surface of the air deflector 140 is set by optical simulation to increase the focusing of infrared light and improve the energy utilization rate of the reflective cover.

[0034] Furthermore, the infrared emitting component 100 also includes a first shell 150, which is buckled on the top of the air duct 140 and connected to the air duct 140. The first shell 150 and the air duct 140 are arranged to form a first cooling cavity 120. A first cold air hole 141 is provided on the top of the air duct 140, and the first cooling cavity 120 is connected to the inside of the air duct 140.

[0035] Specifically, the cross section of the first shell 150 is a rectangular arrangement with an open bottom, and is buckled on the top of the air deflector 140. In this embodiment, a mounting groove is provided on the outside of the air deflector 140, and the bottom of the first shell 150 can extend into the mounting groove and snap into the air deflector 140. The first shell 150 is arranged along the extension direction of the air deflector 140, and sealing plates are provided on both sides of the first shell 150, and the top of the air deflector 140 cooperates with the air deflector 140 to form a first cooling chamber 120. The first air inlet 130 is provided on the sealing plate, and cold air is introduced into the first cooling chamber 120 through an external cold air source. The air deflector 140 is provided with a first cold air hole 141, so that cold air can enter the air deflector 140 to cool the back of the infrared emitting tube 110. In order to improve the cooling uniformity of the infrared emitting tube 110, the first cold air hole 141 can be set as a plurality of circular holes evenly arranged along the extension direction of the infrared emitting tube 110, or the first cold air hole 141 can be set as a long slot hole to improve the cold air transmission efficiency.

[0036] Preferably, the hot air channel 200 includes two interconnected channel side panels 220, and a hot air hole is provided on any channel side panel 220, and the hot air hole is used to connect to the hot air source. The two channel side panels 220 are gradually approached to one side close to the air nozzle 210 to enclose and form an extrusion air duct 230.

[0037] Specifically, the two channel side panels 220 can be provided with metal materials made of sheet metal. One of the channel side panels 220 is welded or bolted to the side wall of the first shell 150 and is arranged in a "J" shape. A plurality of hot air holes are evenly arranged on the top thereof, and the hot air holes can be arranged as round holes or long slot holes. The other channel side panel 220 can be connected to the above-mentioned channel side panel 220 by welding, and the two ends of the channel side panel 220 are welded to the sealing plate, thus forming a complete hot air channel 200. The distance between the two channel side panels 220 decreases from top to bottom, and an extrusion air duct 230 is gradually formed, and the air nozzle 210 is arranged at the outlet of the extrusion air duct 230. Therefore, by setting the extrusion air duct 230, the hot air flow rate through the air nozzle 210 can be increased, so that the hot air is blown to the parts to be dried at a high speed, thereby improving the drying efficiency of the parts to be dried.

[0038] Furthermore, the drying device further includes a second shell 300 , one side of the second shell 300 is connected to the air deflector 140 , and the other side of the second shell 300 is connected to the channel side plate 220 .

[0039] Specifically, a slot is provided at the top of the second shell 300, and a block corresponding to the slot is provided at the bottom of the air deflector 140, so that the bottom of the air deflector 140 can be inserted into the slot, and the air deflector 140 and the second shell 300 are connected. The bottom of the second shell 300 is connected to the channel side plate 220, and the connection method can be set to welding, bonding, or bolt connection. Thus, the second shell 300 is connected to the air deflector 140 and the channel side plate 220 respectively, so that the second shell 300 can play a role in manufacturing the air deflector 140 and the channel side plate 220, thereby improving the strength of the drying device and ensuring that the hot air channel 200 remains stable when blowing hot air to the parts to be dried.

[0040] Preferably, two second shells 300 are provided, and the two second shells 300 are respectively connected to two sides of the opening end of the air deflector 140 , and the second shells 300 and the air deflector 140 are surrounded to form a air deflector cavity 142 .

The second shell 300 is in the shape of an elongated strip as a whole, and its length is consistent with the length of the air guide cover 140, and cooperates with the air guide cover 140 to form a air guide cavity 142. On the one hand, the infrared emitting tube 110 is completely arranged in the air guide cavity 142 to protect the infrared emitting tube 110, and at the same time, the second shell 300 is extended at the bottom of the air guide cover 140 to further extend the reflection surface, thereby improving the air guide effect of the entire infrared emitting assembly 100 and increasing the focusing of the infrared light.

[0042] Furthermore, the infrared emitting assembly 100 further includes a protection plate 160 , two sides of which are respectively connected to the two second shells 300 to seal the flow guiding cavity 142 , and the protection plate 160 is transparent.

[0043] Specifically, a mounting groove is provided at the bottom of the second housing 300, and two mountings are arranged opposite to each other.

The protective plate 160 is provided as a transparent glass plate, so that the infrared light can pass through the protective plate 160 and irradiate the parts to be dried. Therefore, by providing the protective plate 160 at the bottom of the flow guiding cavity 142, the user can be effectively prevented from accidentally touching the infrared emitting tube 110, thereby reducing the risk of injury to the user or damage to the infrared emitting tube 110.

[0044] Preferably, the second shell 300, the channel side plate 220 and the first shell 150 are arranged to form a second cooling chamber 310, and a second cold air hole 320 is arranged on the second shell 300 to connect the second cooling chamber 310 with the guide chamber 142, and a second air inlet hole 330 is arranged at one end of the second cooling chamber 310.

[0045] Specifically, the two ends of the second shell 300 are connected to the sealing plates at the two ends of the air guide cover 140 respectively. In other words, the second shell 300, the channel side plate 220 and the first shell 150 are surrounded to form a second cooling chamber 310. The second air inlet 330 is arranged on the sealing plate and connected to the cold air source so that cold air can enter the second cooling chamber 310 from the outside. At the same time, a second cold air hole 320 is arranged on the second shell 300 to connect the second cooling chamber 310 with the air guide chamber 142, so that cold air can enter the air guide chamber 142 through the second cold air hole 320, thereby lowering the temperature in the air guide chamber 142 and further cooling the infrared emitting tube 110.
