Description

Technical Field

[0001] This utility model relates to the field of resin fiber tube spray painting technology, and in particular to an automatic resin fiber tube spray painting device. Background Technology

[0002] After being cut and polished, the resin fiber tubes need to be painted on both the inner and outer surfaces. A robot is introduced into the painting process to automatically move the nozzles. The painting process can be completed simply by rotating and adjusting the resin fiber tube. After each resin fiber tube is painted, it is replaced and the painting continues. The existing painting equipment has only one painting station, and painting can only continue after the material is loaded. Therefore, the robot is idle during the loading and unloading process, resulting in low efficiency. At the same time, a lot of paint mist is generated during the painting process. Currently, negative pressure fans are mainly used to exhaust the paint mist from the painting position. Although this can protect the painted area, there is no external emission treatment process. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] See Figures 1-4 As shown in the figure, an automatic resin fiber tube painting device is proposed in the embodiment of this utility model, including a base 1 and a machine tool 2 mounted on the base 1. Two sliding guide rails 3 are installed at intervals on the machine tool 2. A rotary host 4 and a pneumatic chuck 5 connected to the rotary host 4 are installed on one side of each sliding guide rail 3. A positioning seat 6 is slidably installed on the sliding guide rail 3. The pneumatic chuck 5 clamps the resin fiber tube, and the positioning seat 6 supports the end of the resin fiber tube. By setting two sliding guide rails 3, two rotary hosts 4, two starting chucks, and two positioning seats 6 on the machine tool 2, two workstations can be set up to operate independently. This allows the other workstation to load and unload materials while one workstation is painting, thereby realizing continuous painting at two workstations and improving efficiency. Specifically, a six-axis painting robot 7 is installed on the base 1, located on one side of the machine tool 2. This six-axis painting robot 7 is existing technology, primarily used for adjusting the painting position and performing continuous operation based on the material loading and unloading situation at both workstations. One operator can work with the six-axis painting robot 7 to continuously switch between the two workstations for painting operations. Specifically, an extended painting rod 17 is integrated at the end of the robotic arm of the six-axis painting robot 7. A paint nozzle 18 is installed at the end of the extended painting rod 17. The extended painting rod 17 allows the nozzle to travel the entire length of the resin fiber tube in a single movement.

[0026] Specifically, the positioning seat 6 includes a sliding seat 61 slidably mounted on the sliding guide rail 3. The sliding seat 61 has a placement notch 62. The sliding seat 61 is equipped with a bracket 63 extending toward the placement notch 62 and located on both sides of the placement notch 62. A rolling guide roller 64 is rotatably mounted on the bracket 63. The resin fiber tube is placed through the placement notch 62 and supported on the rolling guide roller 64, thereby supporting and limiting the end of the resin fiber tube and ensuring flexible rotation.

[0027] During the painting process, a significant amount of paint mist is dispersed. To prevent this mist from flowing directly outwards, a dustproof chamber 8 is installed on the base 1, covering the machine tool 2. This dustproof chamber 8 shields the paint mist inside, preventing it from being emptied before proper treatment. Simultaneously, a water curtain wall 9 is installed inside the dustproof chamber 8, and a water circulation system connected to the water curtain wall 9 is installed on the base 1. The circulating water through the water curtain wall 9 causes paint impurities to quickly condense and be filtered through the water circulation system, thereby reducing the paint particle content in the internal air. Furthermore, a paint mist emission system is installed at the top of the dustproof chamber 8. This system further extracts and treats most of the dispersed paint mist before venting it out, significantly reducing the paint particle concentration inside the dustproof chamber 8.

[0028] The water circulation system includes a water collection tank located at the bottom of the water curtain wall 9. The water collection tank is connected to the water curtain wall 9 by a circulating water pipe. A circulating water pump is installed on the circulating water pipe, and an impurity filter is installed at the inlet of the circulating water pump. The water collection tank is used to collect the water flow left on the water curtain wall 9. The circulating water pump continuously supplies water to the water curtain wall 9 to form a circulating flow. The impurity filter integrated in the water flow pipeline filters out solidified paint particles. The water curtain wall 9 can effectively capture and purify paint mist, reduce the emission of paint mist and harmful gases into the atmosphere, and reduce pollution to the surrounding environment.

[0029] Furthermore, the paint mist emission system includes a gas collection hood 10 installed on the top of the dustproof booth 8 and a duct 11 connected to the gas collection hood 10. The end of the duct 11 is connected to a VOC catalytic combustion exhaust gas treatment device 12. The exhaust port of the VOC catalytic combustion exhaust gas treatment device 12 is connected to a centrifugal fan 13, and the outlet of the centrifugal fan 13 is connected to an exhaust pipe 14. The paint mist inside is guided by the gas collection hood 10 through the duct 11 into the VOC catalytic combustion exhaust gas treatment device 12 for treatment before being discharged. The centrifugal fan 13 is used to accelerate the internal airflow speed. The VOC catalytic combustion exhaust gas treatment device 12 is a mature product. Under the action of a catalyst, VOCs in the exhaust gas undergo an oxidation reaction at a relatively low temperature (200-400℃), decomposing VOCs into carbon dioxide (CO2) and water (H2O). The catalyst can lower the activation energy of the reaction, causing reactant molecules to accumulate on the catalyst surface, thereby increasing the reaction rate. This treats the harmful exhaust gas in the paint mist to meet the discharge requirements.

[0030] Meanwhile, a cyclone mixing tower 15 is connected between the gas collection hood 10 and the air duct 11. The cyclone mixing tower 15 is a high-efficiency wet environmental protection waste gas purification device. Utilizing the principles of fluid mechanics, centrifugal force is obtained by designing the tangential angle of the cyclone device. Under the traction force of the fan, the dust-laden gas enters the high-pressure centrifugal cyclone device tangentially, forming a high-speed rotating cyclone. This allows the liquid and dust-laden gas to fully dissolve and mutually adsorb, and the cyclone energy is attenuated through circular motion, thereby achieving the purpose of dust removal.

[0031] Meanwhile, multiple stacked activated carbon adsorption boxes 16 are connected between the air inlet of the centrifugal fan 13 and the VOC catalytic combustion exhaust gas treatment device 12, so that the treated gas is further adsorbed by activated carbon before being discharged.

[0032] Meanwhile, a gas detection sensor for detecting exhaust gas concentration is installed at the end of the exhaust pipe 14. The gas detection sensor detects the exhaust gas concentration, thereby facilitating the timely detection of excessive exhaust gas emissions.
