Description

Technical Field

[0001] This utility model relates to the technical field of plastic product dyeing equipment, and in particular to a dyeing and spraying device. Background Technology

[0002] In industrial production, especially for the surface treatment of small workpieces, models, or specific parts, spray painting is a common process. Traditional spray painting equipment or workbenches typically employ an open or semi-open design, generating large amounts of paint mist and volatile organic compounds (VOCs) during spray painting operations. If these harmful substances are not effectively collected and treated, they will directly diffuse into the workshop air, not only seriously polluting the working environment and endangering the health of operators, but also causing atmospheric pollution.

[0003] To address the aforementioned issues, existing technologies often employ spray booths or spray cabinets equipped with external ventilation ducts. While these devices can collect and centrally discharge exhaust gases to some extent, they still have several shortcomings: First, their airflow organization is often not scientifically sound, resulting in low exhaust gas collection efficiency and potentially causing some pollutants to escape within the work area; second, for liquid paint particles that do not adhere to the workpiece during the painting process and settle (overspray mist), traditional methods may involve setting up a water curtain or simple collection tank at the bottom, but if the collected paint residue is not properly handled, the harmful gases generated by its slow volatilization may still become a secondary source of pollution; furthermore, many devices have low integration of conveying, positioning, painting, and exhaust gas treatment systems, resulting in large equipment footprints, low workpiece turnover efficiency, and difficulty in achieving efficient, continuous, and automated production.

[0004] Therefore, there is an urgent need in this field for an integrated spray painting and dyeing device that is compact in design, has high waste gas collection efficiency, can effectively prevent secondary pollution, and is easy to automate. Utility Model Content

[0005] Therefore, it is necessary to provide a dyeing and painting device that addresses the technical problem of secondary pollution easily caused by the exhaust gas collection process of existing dyeing and painting equipment.

[0006] A dyeing and painting apparatus includes a base, a top frame, a conveying mechanism, and a painting unit. The top frame covers the top side surface of the base. The conveying mechanism and the painting unit are installed on the top side surface of the base and housed inside the top frame. The conveying mechanism is movably installed on the base. The painting unit is disposed adjacent to the conveying mechanism and installed on the base corresponding to the positioning point of the conveying mechanism, thereby forming a dyeing station for the workpiece.

[0007] The top frame includes a working chamber, an exhaust chamber, and a ventilation chamber. Both the working chamber and the ventilation chamber are located on the top side surface of the base, with the ventilation chamber located adjacent to the working chamber. The exhaust chamber is located on the top side of the working chamber and is connected to the working chamber. A liquid collection chamber is located on the bottom side of the base corresponding to the dyeing station. One end of the liquid collection chamber is connected to the ventilation chamber, and the other end is connected to the working chamber. The conveying mechanism and the painting unit are installed inside the working chamber.

[0008] In one embodiment, the exhaust gas discharge chamber is provided with a partition, a plurality of filters and a first cover.

The plurality of air guide holes are arranged at equal intervals along the length of the partition, and the plurality of filters are respectively matched with the plurality of air guide holes one by one.

[0011] In one embodiment, the ventilation cavity includes a ventilation duct and a second cover. The ventilation duct is disposed on the adjacent side of the working cavity and the exhaust cavity along the height direction of the top frame. The second cover covers the top of the ventilation duct. The bottom end of the ventilation duct is connected to the liquid collection cavity.

[0012] In one embodiment, the top of the second cover is provided with an air inlet, which connects the inner and outer sides of the second cover.

[0013] In one embodiment, a liquid collection hopper is provided on the top side of the liquid collection cavity, and the liquid collection hopper is located on the bottom side of the dyeing station and connected to the inside of the liquid collection cavity of the base.

[0014] In one embodiment, the conveying mechanism includes a rotating fixture and a conveying guide rail; the conveying guide rail is mounted on the top side of the liquid collecting hopper, with one end extending to the open side of the working cavity and the other end extending to the inside of the working cavity and abutting against the side wall of the working cavity; the rotating fixture is slidably fitted to the conveying guide rail.

[0015] In one embodiment, a door is movably provided on the open side of the aforementioned working cavity.

[0016] In one embodiment, the door is made of a transparent material to form an observation window.

The airflow causes gaseous pollutants to move upwards from the working chamber and the liquid collection chamber, where they are filtered and absorbed by the exhaust gas chamber before being discharged to the outside. This design ensures that most pollutants are treated in a timely manner, reducing the amount of harmful substances directly emitted into the environment and meeting environmental protection requirements. The liquid collection chamber, located at the bottom of the dyeing station, collects small amounts of falling ink droplets and guides volatile gases into the exhaust gas system via airflow. This avoids evaporation or leakage caused by liquid accumulation, reduces the risk of secondary pollution, and improves overall environmental safety. Furthermore, the working chamber, exhaust gas chamber, and ventilation chamber are integrated within the top frame, resulting in a compact structure and optimized space utilization. The conveying mechanism and painting unit are both installed in the working chamber, allowing the entire painting process to be carried out centrally, shortening the workpiece transfer path and improving production speed.

[0028] Please see Figures 1 to 3This utility model discloses a dyeing and painting device 1, which includes a base 10, a top frame 20, a conveying mechanism 30, and a painting unit 40. The top frame 20 covers the top side surface of the base 10. The conveying mechanism 30 and the painting unit 40 are installed on the top side surface of the base 10 and housed inside the top frame 20. The conveying mechanism 30 is movably installed on the base 10, so that the conveying mechanism 30 can drive the workpiece to move along a preset trajectory inside and outside the top frame 20, thereby realizing the material conveying, positioning, and unloading process. The painting unit 40 is disposed on the adjacent side of the conveying mechanism 30 and is installed on the base 10 corresponding to the positioning point of the conveying mechanism 30, thereby forming a dyeing station for the workpiece and completing the dyeing and painting process. Specifically, the top frame 20 includes a working chamber 21, an exhaust gas chamber 22, and a ventilation chamber 23. Both the working chamber 21 and the ventilation chamber 23 are located on the top side surface of the base 10. The ventilation chamber 23 is located on the adjacent side of the working chamber 21. The exhaust gas chamber 22 is located on the top side of the working chamber 21 and is connected to the working chamber 21. Correspondingly, a liquid collection chamber 11 is provided on the bottom side of the base 10 corresponding to the dyeing station. One end of the liquid collection chamber 11 is connected to the ventilation chamber 23, and the other end of the liquid collection chamber 11 is connected to the working chamber 21. Based on this, the conveying mechanism 30 and the painting unit 40 are installed in the working chamber 21, thereby completing the painting and dyeing work of the workpiece in the working chamber 21. During the actual dyeing process, the workpiece is conveyed to the dyeing station via the conveying mechanism 30. The painting unit 40 paints and dyes the workpiece. The ventilation chamber 23 continuously delivers directional airflow to the liquid collection chamber 11 and the working chamber 21, causing gaseous pollutants inside the liquid collection chamber 11 and the working chamber 21 to be filtered and discharged to the outside of the device through the exhaust gas discharge chamber 22 on the top side. Thus, most of the ink mist generated during the dyeing process is filtered and discharged through the exhaust gas discharge chamber 22 on the top side, and a small amount of ink mist falls into the liquid collection chamber 11 on the bottom side. The volatile gases generated by the evaporation of ink inside the liquid collection chamber 11 are also filtered, absorbed, and discharged through the exhaust gas discharge chamber 22 along with the airflow direction. Based on the above settings, the dyeing and painting device 1 of this scheme is directly connected to the working chamber 21 through the exhaust gas discharge chamber 22 of the top frame 20, and combined with the directional airflow provided by the ventilation chamber 23, it can effectively collect the ink mist generated during the painting process. Airflow causes gaseous pollutants to move upwards from the working chamber 21 and the liquid collection chamber 11, where they are filtered and absorbed by the exhaust gas discharge chamber 22 before being discharged to the outside. This design ensures that most pollutants are treated in a timely manner, reducing the amount of harmful substances directly emitted into the environment and meeting environmental protection requirements. The liquid collection chamber 11, located at the bottom of the dyeing station, collects small amounts of ink droplets that fall in and guides volatile gases into the exhaust gas discharge system via airflow. This avoids evaporation or leakage caused by liquid accumulation, reduces the risk of secondary pollution, and improves overall environmental safety.Furthermore, the working chamber 21, exhaust chamber 22, and ventilation chamber 23 are integrated within the top frame 20, resulting in a compact structure and optimized space utilization. The conveying mechanism 30 and the painting unit 40 are both installed in the working chamber 21, allowing the entire painting process to be carried out in a centralized manner, shortening the workpiece transfer path, and improving the production pace.

[0029] Furthermore, the exhaust gas discharge chamber 22 is provided with a partition 221, a plurality of filters 222, and a first cover 223.

The plurality of filters 222 are disposed on the top side of the partition 221, and each filter 222 is connected to the working chamber 21 through the partition 221. The first cover 223 is disposed on the top side of the plurality of filters 222. The exhaust gas output from the working chamber 21 and the liquid collection chamber 11 is filtered and absorbed by the plurality of filters 222 and then discharged to the outside of the device through the first cover 223.

[0030] Specifically, in one embodiment, the top of the first cover 223 is provided with an exhaust section 2231, which connects the inner and outer sides of the first cover 223 to facilitate the discharge of filtered airflow.

[0032] Furthermore, the ventilation chamber 23 includes a ventilation duct 231 and a second cover 232.

The airflow can be transported into the ventilation duct 231 through the second cover 232 by an external fan, and then flow back to the outside atmosphere in sequence through the liquid collection chamber 11, the working chamber 21 and the exhaust gas discharge chamber 22.

[0033] Specifically, in one embodiment, the top of the second cover 232 is provided with an air inlet 2321, which connects the inner and outer sides of the second cover 232 so that an external fan can blow airflow into the ventilation duct 231.

[0034] Furthermore, a liquid collection hopper 111 is provided on the top side of the liquid collection chamber 11.

The rotating fixture 31 is slidably fitted to the conveying guide rail 32, thereby enabling the rotating fixture 31 to reciprocate along the conveying guide rail 32 from the open side of the working chamber 21 toward the dyeing station. Specifically, in one embodiment, a door 211 is movably provided on the open side of the working chamber 21 to realize the opening and closing function of the working chamber 21. More specifically, in another embodiment, the door 211 is made of transparent material to form an observation window.

[0036] Specifically, in one embodiment, the rotating fixture 31 includes a carrier plate 311, a rotating body 312, a chuck 313, and several clamps 314.

Correspondingly, the output end of the painting unit 40 is movably set in conjunction with the several clamps 314.

[0037] More specifically, in one embodiment, the rotating fixture 31 further includes a rotating motor 315, which is housed inside the carrier plate 311, and the output end of the rotating motor 315 is driven to the bottom of the rotating body 312, thereby driving the rotating body 312 to rotate relative to the carrier plate 311.

[0038] In summary, the dyeing and painting device disclosed in this utility model directly connects the exhaust chamber of the top frame to the working chamber, and combined with the directional airflow provided by the ventilation chamber, effectively collects the ink mist generated during the painting process.
