Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically an environmentally friendly spraying and drying device for environmentally friendly vehicles. Background Technology

[0002] Environmentally friendly vehicles are green transportation tools that use new energy power (such as pure electric or hybrid), low emission or zero emission design, and whose body materials contain recyclable components. The core is to reduce environmental pollution and resource consumption through technology. Its core components include power system (battery pack, motor, electronic control unit), body structure (aluminum alloy frame, composite material doors / covers), chassis components (lightweight suspension arms, low rolling resistance wheels) and interior components (biodegradable plastic dashboard, recycled fiber seats).

[0003] Environmental protection vehicle parts spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force, and then applies the coating to the surface of the object. It can be divided into atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc.

[0004] Existing environmentally friendly vehicle parts require drying after painting. During use and observation, it was found that drying is usually done by placing them in a heating box. During drying, the internal temperature of the heating box needs to be frequently adjusted to reduce paint cracking, making the drying process quite cumbersome.

[0005] Therefore, an environmentally friendly vehicle coating and drying device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An environmentally friendly vehicle coating and drying device of this utility model includes a base, a motor fixedly connected to the side wall of the base; a conveyor belt is provided in the middle of the base; a heating channel is fixedly connected to the top of the base; an inlet and an outlet are sequentially opened at the end of the heating channel; a preheating zone, a medium-temperature zone, and a high-temperature curing zone are sequentially opened inside the heating channel; the preheating zone is located near the inlet; multiple heating wires are fixedly connected inside the preheating zone, the medium-temperature zone, and the high-temperature curing zone; by dividing the heating channel into multiple zones, the moving speed of the conveyor belt can be moderate during the drying process, and the parts are gradually dried by multiple zones as they enter the heating channel. This zoned drying process reduces stress caused by uneven internal and external shrinkage during the coating drying process, thereby reducing cracking.

[0008] Preferably, the high-temperature curing zone has an air inlet at the top; the air inlet is connected to a guide pipe; the preheating zone has an air outlet at the top; the guide pipe and the air outlet are connected; by adding a guide pipe, the high-temperature gas inside the high-temperature curing zone can be guided to flow into the preheating zone for use. At the same time, the airflow will also eliminate some heat energy during its movement, thereby reducing the heat in the airflow and achieving the desired temperature in the preheating zone.

[0009] Preferably, a first insulation sleeve is fixedly connected to the end of the heating channel; the first insulation sleeve is sleeved on the end of the guide tube; a second insulation sleeve is slidably connected inside the first insulation sleeve; by adding the first insulation sleeve and the second insulation sleeve, the surface of the guide tube can be protected when the airflow temperature is reduced due to rapid heat exchange in the guide tube, thereby increasing the heat preservation effect of the guide tube.

[0010] Preferably, a support frame is fixed to the surface of the conveyor belt; multiple support frames are provided on the conveyor belt; by adding support frames, the parts can be lifted up, thereby increasing the contact area of ​​the parts and thus accelerating the overall drying of the parts by the airflow.

[0011] Preferably, a baffle is slidably connected inside the air outlet; the baffle is slidably connected to the heating channel; by adding a baffle to open and close the air outlet, excessive air intake can be reduced to prevent excessive heating when airflow enters, thereby increasing control over the air outlet.

[0012] Preferably, multiple heat insulation pads are fixedly connected inside the heating channel; the heat insulation pads are located between each zone; by adding heat insulation pads, heat loss can be reduced when the heating wire is heating, thereby reducing temperature crosstalk when the parts are drying.

The environmentally friendly paint spraying and drying device for vehicles described in this utility model divides the heating channel into multiple zones. When the parts are being dried, the conveyor belt moves at a moderate speed, and as they enter the heating channel, they are gradually dried by the multiple zones. This zoned drying process reduces the stress caused by uneven internal and external shrinkage, thereby reducing cracking.

[0014] 2. The environmentally friendly vehicle spraying and drying device of this utility model can guide the high-temperature gas inside the high-temperature curing zone by adding a guide pipe, so that it flows into the preheating zone for use. At the same time, the airflow will also eliminate some heat energy during movement, thereby reducing the heat in the airflow and thus achieving the temperature of the preheating zone.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the embodiment of this utility model, an environmentally friendly vehicle spraying and drying device includes a base 1, a motor 11 fixedly connected to the side wall of the base 1; a conveyor belt 12 is provided in the middle of the base 1; a heating channel 13 is fixedly connected to the top of the base 1; an inlet 14 and an outlet 15 are sequentially opened at the ends of the heating channel 13; a preheating zone 16, a medium-temperature zone 17, and a high-temperature curing zone 18 are sequentially opened inside the heating channel 13; the preheating zone 16 is located near the inlet 14; multiple heating wires 19 are fixedly connected inside the preheating zone 16, the medium-temperature zone 17, and the high-temperature curing zone 18; during operation, when drying the parts, the motor 11 is started first to drive the conveyor belt 12 to roll. At this time, the rotation speed of the conveyor belt 12 is set to a relatively slow speed to achieve the desired time to complete the entire heating channel 13. At the same time, multiple heating wires 19 are turned on. When the heating wires 19 are turned on, the heating channel 13 is heated. Heating will begin, and during this process, the upper limit of the temperature of the heating wire 19 inside the high-temperature curing zone 18 will be set higher than that of the heating wire 19 inside the medium-temperature zone 17. The coated parts will then be placed on the surface of the conveyor belt 12. Once inside the heating channel 13, the parts will be preheated by the temperature inside the preheating zone 16, allowing the solvent in the coating to initially evaporate. After entering the medium-temperature zone 17, the temperature will rise, promoting initial curing of the coating. Finally, the parts will enter the high-temperature curing zone 18, where the coating will be fully cured, thus completing the drying process. The parts will then exit the heating channel 13 through the discharge port 15, at which point they will be collected. By dividing the heating channel 13 into multiple zones, the moving speed of the conveyor belt 12 can be moderate during the drying process. As the parts enter the heating channel 13, they are gradually dried by the multiple zones. This zoned drying process reduces stress caused by uneven internal and external shrinkage during the coating drying process, thereby reducing cracking.

[0021] like Figures 1 to 3 As shown, the high-temperature curing zone 18 has an air inlet 2 at its top; the air inlet 2 is connected to a guide pipe 21; the preheating zone 16 has an air outlet 22 at its top; the guide pipe 21 and the air outlet 22 are connected. During operation, the high-temperature curing zone 18 has the highest temperature, and the air molecules inside the high-temperature curing zone 18 are more active. Subsequently, they enter the guide pipe 21 through the air inlet 2. The subsequent airflow will gradually push the airflow inside the guide pipe 21 forward. When the airflow moves inside the guide pipe 21, it will consume some heat energy, thereby reducing the stability of the airflow itself. Finally, when it enters the preheating zone 16 through the air outlet 22, the temperature difference between the airflow and the temperature inside the preheating zone 16 is small, thus allowing it to be utilized. By adding the guide pipe 21, the high-temperature gas inside the high-temperature curing zone 18 can be guided to flow into the preheating zone 16 for use. At the same time, the airflow will also eliminate some heat energy during its movement, thereby reducing the heat in the airflow and achieving the desired temperature in the preheating zone 16.

[0022] like Figures 1 to 3As shown, a first insulation sleeve 3 is fixedly connected to the end of the heating channel 13; the first insulation sleeve 3 is sleeved on the end of the guide pipe 21; a second insulation sleeve 31 is slidably connected inside the first insulation sleeve 3; during operation, when the heat consumption of the airflow transmitted by the guide pipe 21 is relatively large, the second insulation sleeve 31 can be pulled out from inside the first insulation sleeve 3. After being pulled out, it will insulate part of the guide pipe 21, thereby reducing the heat exchange between the guide pipe 21 and the outside world; by adding the first insulation sleeve 3 and the second insulation sleeve 31, the surface of the guide pipe 21 can be protected when the airflow temperature drops rapidly due to heat exchange in the guide pipe 21, thereby increasing the heat preservation effect of the guide pipe 21.

[0023] like Figures 2 to 3 As shown, a support frame 4 is fixedly attached to the surface of the conveyor belt 12; multiple support frames 4 are provided on the conveyor belt 12; during operation, when placing parts, the support frame 4 will lift the parts, causing the parts to leave the surface of the conveyor belt 12. After leaving the surface, the contact with air will increase, thereby increasing the contact area with the airflow after entering the heating channel 13; by adding support frames 4, the parts can be lifted, thereby increasing the contact area of ​​the parts and thus accelerating the overall drying of the parts by the airflow.

[0024] like Figures 4 to 5 As shown, a baffle 5 is slidably connected inside the air outlet 22; the baffle 5 is slidably connected to the heating channel 13; during operation, when the airflow enters the preheating zone 16 through the air outlet 22, the outflow area of ​​the air outlet 22 can be controlled by pulling the baffle 5, thereby increasing the airflow rate; by adding the baffle 5 to open and close the air outlet 22, excessive air intake can be reduced, which can cause the temperature to rise too quickly, thereby increasing the control of the air outlet 22.

[0025] like Figures 3 to 4 As shown, multiple heat insulation pads 6 are fixed inside the heating channel 13; the heat insulation pads 6 are located between each zone; during operation, when all the heating wires 19 inside the heating channel 13 are turned on, the heat insulation pads 6 will reduce the temperature transfer between zones, so that the temperature stays within the corresponding zone; by adding heat insulation pads 6, the loss of temperature can be reduced when the heating wires 19 are heating, thereby reducing temperature crosstalk when the parts are drying.

[0026] Working principle: When drying parts, motor 11 is started to drive conveyor belt 12 to rotate. The rotation speed of conveyor belt 12 is set to a slow speed to achieve the desired time to complete the entire heating channel 13. At the same time, multiple heating wires 19 are turned on. When the heating wires 19 are turned on, the interior of heating channel 13 will begin to heat up. During the heating process, the upper limit of the temperature of the heating wires 19 in the high-temperature curing zone 18 is set higher than that of the heating wires 19 in the medium-temperature zone 17. Then, the sprayed parts are placed on the surface of conveyor belt 12. When the parts enter the heating channel 13... After entering the preheating zone 16, the coating is preheated to allow the solvent in the coating to initially evaporate. Then, it enters the medium-temperature zone 17, where the temperature rises to promote initial curing of the coating. Finally, it enters the high-temperature curing zone 18, where the coating is fully cured, thus completing the drying process. Finally, it exits the heating channel 13 through the discharge port 15, at which point the parts are collected. Because the temperature in the high-temperature curing zone 18 is the highest, the air molecules inside are more active. They then enter the guide pipe 21 through the air inlet 2, and the subsequent airflow... The airflow inside the guide tube 21 will gradually move forward. As the airflow moves within the guide tube 21, it consumes some heat energy, thus reducing the stability of the airflow itself. Finally, when it enters the preheating zone 16 through the outlet 22, the temperature difference between the outlet and the preheating zone 16 is small, allowing for utilization. When the heat loss from the airflow transmitted through the guide tube 21 is significant, the second insulation sleeve 31 can be removed from the first insulation sleeve 3. After removal, a portion of the guide tube 21 will be insulated, thereby reducing heat exchange between the guide tube 21 and the outside environment. When placing parts... The support frame 4 lifts the parts, causing them to leave the surface of the conveyor belt 12. This increases the contact area with the air, thereby increasing the contact area with the airflow after entering the heating channel 13. When the airflow enters the preheating zone 16 through the air outlet 22, the outflow area of ​​the air outlet 22 can be controlled by pulling the baffle 5, thereby increasing the airflow rate. When all the heating wires 19 inside the heating channel 13 are turned on, the heat insulation pads 6 reduce the temperature transfer between areas, keeping the temperature within the corresponding zone.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
