[0002] In modern industrial production, guardrail manufacturing is an important field, which involves safety protection and beautiful decoration in many aspects such as construction, transportation, and home. With the development of society and the improvement of people's aesthetic needs, the quality and appearance requirements of guardrail products are getting higher and higher. In order to meet these needs, guardrail manufacturers need to continuously improve production efficiency and product quality, among which painting and drying are one of the key links in the guardrail manufacturing process. In the traditional guardrail manufacturing process, painting and drying are often done manually or with semi-automatic equipment, which not only consumes a lot of manpower and time, but also makes it difficult to ensure the uniformity and adhesion of the paint coating, and is prone to quality problems such as bubbling and sagging. In addition, manual operation also has certain safety risks, such as paint splashing and inhalation of harmful gases. Therefore, an efficient, stable and safe paint drying device for guardrail manufacturing came into being.

[0003] Most of the existing paint drying devices for guardrail manufacturing have the problem of incomplete drying of the guardrail paint and easy bubbling of the paint on the guardrail surface during the drying process. This is mainly because the guardrail is heated unevenly during the drying process. In addition, most of the existing paint drying devices for guardrail manufacturing ignore the post-treatment of dripping paint and harmful gases generated during the drying process, which is a great hazard to both the staff and the environment.

[0035] Embodiment 1: A paint drying device for guardrail manufacturing, comprising a drying box 1, a fixed cylinder 6 is fixedly connected to the outer wall of the drying box 1, a motor 7 is fixedly connected to the outer wall of the top of the drying box 1, a screw 12 is fixedly connected to the driving end of the motor 7, a fixed slider 13 is rotatably connected to the outer wall of the screw 12, the outer wall of the fixed slider 13 is slidably connected to the inner wall of the top of the drying box 1, an adjuster 14 is threadedly connected to the outer wall of the screw 12, a plurality of adjusting rods 15 are rotatably connected to the inner wall of the adjuster 14, and the outer wall of the end of the adjusting rod 15 is A support rod 17 is rotatably connected, and a fixing rod 16 is rotatably connected to the inner wall of the end of the support rod 17. The outer wall of the fixing rod 16 is fixedly connected to the inner wall of the fixing cylinder 6. An anti-skid pad 18 is fixedly connected to the outer wall of the end of the support rod 17. Adjusting rods 15 are rotatably connected to the inner walls of both ends of the regulator 14. The outer wall of the drying box 1 is slidably connected to the box door 2. A large fan 5 is fixedly connected to the outer wall of the drying box 1. A small fan 3 is fixedly connected to the outer wall of the top of the drying box 1. Adjusting rods 15 are rotatably connected to the inner walls of both ends of the regulator 14.

[0036] Specifically, the motor 7 is started so that its driving end drives the screw 12 to rotate, and the screw 12 rotates on the inner wall of the fixed slider 13, so that the adjuster 14 moves along the screw 12 toward the bottom end of the screw 12, thereby driving the adjusting rods 15 on both sides of the adjusters 14 to move downward. Under the action of the adjusting rods 15, the two support rods 17 rotate along the fixed rods 16 and open on both sides, so that the anti-slip pads 18 at the bottom ends of the support rods 17 are attached to the inner wall of the guardrail to achieve a supporting effect, ensuring that the guardrail will not fall due to gravity. The main function of the clamping structure composed of this part is to make the guardrail upright during the drying process, which makes the drying effect better and more uniform, and it is not easy to cause the paint on the surface of the guardrail to bubble.

[0037] Embodiment 2: A box door 2 is slidably connected to the outer wall of the drying box 1, a large fan 5 is fixedly connected to the outer wall of the drying box 1, a collecting plate 10 is slidably connected to the outer wall of the bottom end of the drying box 1, a filter screen 9 is arranged on the top of the collecting plate 10, and the filter screen 9 is made of a phenolic resin filter element, a small fan 3 is fixedly connected to the outer wall of the top end of the drying box 1, an exhaust cover 8 is arranged on the outer wall of the top end of the drying box 1, an air outlet pipe 4 is fixedly connected to the outer wall of the top end of the drying box 1, an exhaust fan 19 is fixedly connected to the inner wall of the air outlet pipe 4, and activated carbon 11 is arranged on the inner wall of the air outlet pipe 4.

[0038] Specifically, first, when paint drips during the drying process, it will be filtered by the filter screen 9 and finally flow into the groove of the collecting plate 10. Secondly, when the drying is completed, open the exhaust cover 8 and the exhaust fan 19. The exhaust gas generated inside the drying box 1 will enter the air outlet pipe 4 under the action of the exhaust fan 19, and then be filtered by the activated carbon 11, and finally be discharged out of the box. The structure of this part is mainly for treating the waste gas and waste liquid generated during the drying process of the guardrail paint. In addition, the small fan 3 and the large fan 5 can simultaneously heat and dry the inside and outside of the guardrail, which can make the drying of the guardrail more sufficient and the paint distribution more even.

[0039] Working principle: First, the motor 7 drives the screw 12 to rotate at its driving end, and the screw 12 rotates on the inner wall of the fixed slider 13, so that the adjuster 14 moves along the screw 12 toward the bottom end of the screw 12, thereby driving the adjusting rods 15 on both sides of the adjusters 14 to move downward. Under the action of the adjusting rods 15, the two support rods 17 rotate along the fixed rods 16 and open on both sides, so that the anti-slip pads 18 at the bottom ends of the support rods 17 fit against the inner wall of the guardrail, and then close the box door 2, start the small fan 3 and the large fan 5, and dry the guardrail. When the drying is completed, open the exhaust cover 8 and the exhaust fan 19, and the exhaust gas generated inside the drying box 1 will enter the air outlet 4 under the action of the exhaust fan 19, and then be filtered by the activated carbon 11, and finally be discharged out of the box, and finally open the box door 2, take out the filter 9 and the collecting plate 10.
