Description

Technical Field

[0001] This utility model relates to the technical field of dovetail clip painting equipment, and in particular to a painting device for dovetail clips. Background Technology

[0002] After the dovetail clips are manufactured, a dovetail clip painting device is used to paint them to prevent rust. The existing dovetail clip painting device is as follows:

[0003] For example, patent publication number CN221157322U discloses a dovetail clamp painting device, which includes a base, two rotating disks driven to rotate on the base, a clamp set on the rotating disks, and a paint spraying component set on the base. It also includes: a sealing cover, a connecting rod with an internal chamber, an air guide, an air outlet, and a filter. The connecting rod has several air inlets communicating with the chamber. It can purify the paint smell and reduce the harm of the paint smell to people's health. The air is transmitted to the outside through the air outlet, thereby realizing the discharge of the air. By directly filtering the gas during the painting process, it can prevent the gas from leaking into the outside and causing pollution to the outside air. It can also effectively prevent harmful gases from harming people and thus prevent harmful gases from harming human health.

[0004] The aforementioned dovetail clamp painting device uses a series clamps to hold the workpiece, and a rotating base drives the clamp to rotate at a constant speed. Simultaneously, a fixed-position painting component sprays paint onto the rotating clamp. While this mechanical structure can complete the basic painting operation, it suffers from a significant process interruption defect: after each batch of clamps is painted, the entire system must be paused until the paint film is fully cured before the finished product can be unloaded and the workpiece to be processed can be re-clamped. This intermittent operation mode results in a large amount of ineffective waiting time, severely restricting overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a painting device for dovetail clips that can dry the dovetail clips.

[0006] To achieve the above objectives, this utility model proposes a painting device for dovetail clips, comprising: a housing and a paint spray head disposed within the housing.

[0007] The box is equipped with two sets of transmission components, which can respectively transmit the paint to the spray head and are arranged opposite each other. The box is equipped with a drying component corresponding to the transmission components, which can dry the dovetail clips.

[0008] The transmission component includes a movable base, a rotating disk, a sealing plate, and several hooks;

[0009] The movable seat is slidably connected to the housing, the rotating disk is rotatably connected to the movable seat, and the plurality of hooks are fixedly connected to the rotating disk, and the hooks can be arranged opposite to the paint spray head.

[0010] The sealing plate is driven to slide vertically within the chamber, and the drying component is located on the side of the sealing plate away from the paint spray head.

[0011] Preferably, the drying component includes a fan fixedly connected to the top surface of the chamber and an air inlet pipe fixedly connected to the inner wall of the chamber and having a built-in chamber. The fan is connected to the air inlet pipe through a pipe. A heating wire is fixedly connected inside the air inlet pipe. An air outlet is provided on the air inlet pipe, and the air outlet is arranged opposite to the hook.

[0012] Preferably, an air guide frame is fixedly connected to the air outlet, and the air guide frame is arranged opposite to the hook.

[0013] Preferably, a sealing door communicating with the box body is sway-connected to the side wall of the box body, and one end of the sealing door is detached and fixed to the box body by a buckle.

[0014] Preferably, an air outlet pipe is fixedly connected to the housing, and a manual valve is fixedly connected to the air outlet pipe.

[0015] Preferably, the two sets of transmission components are arranged in an L-shape, and an L-shaped limiting plate is fixedly connected inside the box. The transmission components can respectively abut against the side wall of the L-shaped limiting plate.

[0016] Preferably, a cushioning sponge is fixedly connected to the side wall of the L-shaped plate.

[0017] The beneficial effects of this utility model compared with the prior art are as follows:

[0018] 1. By setting up two sets of L-shaped opposing mechanical transfer units within a closed enclosure, seamless connection and alternating operation of the spraying and drying processes are achieved. The core of each transfer unit is a sliding seat that can slide within the enclosure. The seat carries a rotating disk driven by an independent motor, with rigid hooks evenly distributed around its circumference for suspending dovetail clips. Driven by an electric push rod, the seat moves along a predetermined track, its termination position precisely defined by an L-shaped limiting plate fixed to the enclosure and cushioning sponge attached to its surface, ensuring the hook array stops accurately directly below the spray nozzle. Once the seat is positioned, the rotating disk drives the hooks and suspended dovetail clips to rotate at a uniform speed, ensuring the paint sprayed from the nozzle evenly covers the clip surface. After one set of transfer units completes spraying, the electric push rod pulls it back to its initial position; simultaneously, the other set of transfer units moves forward to the spraying station for operation. The switching interval between the two sets of units allows one set to perform painting while the other performs drying, part removal, and part loading, thereby reducing unnecessary dovetail clip drying waiting time and further improving the production efficiency of the dovetail clips.

[0019] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0028] like Figures 1 to 3 A painting device for a dovetail clip includes: a housing 1 and a paint spray head 2 disposed inside the housing 1, wherein the paint spray head 2 is connected to an external liquid inlet pipe for conveying paint into the paint spray head 2;

[0029] The housing 1 is equipped with two sets of transmission components 3, which can respectively transmit the paint to the spray head 2 and are arranged opposite each other. The housing 1 is equipped with a drying component 4 corresponding to the transmission components 3, which can dry the dovetail clips.

[0030] The transmission component 3 includes a movable base 5, a rotating disk 6, a sealing plate 7, and several hooks 8.

[0031] The movable seat 5 is slidably connected to the housing 1, and the rotating disk 6 is rotatably connected to the movable seat 5. Several hooks 8 are fixedly connected to the rotating disk 6, and these hooks 8 can be arranged opposite to the paint spray head 2. The movable seat 5 is driven by an electric push rod, which is fixedly connected to the housing 1, and its output shaft is fixedly connected to the movable seat 5. Therefore, the electric push rod can drive the movable seat 5 to move. When the movable seat 5 moves to a certain position, since the two sets of transmission components 3 are arranged in an L-shape, and an L-shaped limiting plate 17 is fixedly connected inside the housing 1, the transmission components 3... Each of the four parts can be attached to the side wall of the L-shaped limiting plate 17. The side wall of the L-shaped plate is fixedly connected to the buffer sponge 18. Therefore, the movable seat 5 will contact the buffer sponge 18 on the L-shaped limiting plate 17, thereby limiting the movement of the movable seat 5. At this time, the rotating disk 6 driven by the motor rotates. The motor is fixedly connected to the movable seat 5, and the output shaft is fixedly connected to the rotating disk 6. Therefore, the rotation of the rotating disk 6 will drive the fixed hook to rotate, so that the fixed hook drives the dovetail clip hanging on the fixed hook to rotate, thereby realizing the paint head 2 to transmit paint to spray the dovetail clip.

[0032] After the dovetail clips are painted, the transmission component 3 resets, and another set of transmission components 3 is transmitted to the paint spray head 2 in a relatively opposite arrangement. The reset transmission component 3 is transmitted to one side of the housing 1, and the sealing plate 7, driven by the cylinder, moves. The cylinder output shaft, which is fixedly connected to the top surface of the housing 1, is fixedly connected to the sealing plate 7, so the cylinder can drive the sealing plate 7 to move, thus separating the housing 1. The other set of unpainted dovetail clips are then painted, and the painted set of dovetail clips is dried by the drying component 4. The drying component 4 includes a fan that is fixedly connected to the top surface of the housing 1. The fan 9 and the air inlet pipe 10, which is fixedly connected to the inner wall of the housing 1 and has an internal chamber, are connected to the air inlet pipe 10 through a pipe. A heating wire 11 is fixedly connected inside the air inlet pipe 10. An air outlet 12 is opened on the air inlet pipe 10. The air outlet 12 is arranged opposite to the hook 8. Therefore, when the fan 9 is started, the fan 9 transmits the outside airflow into the air inlet pipe 10. The heating wire 11 is started. After the heating wire 11 heats the airflow, the airflow is transmitted through the air outlet 12 into the housing 1 to dry the dovetail clips, further improving the drying effect of the dovetail clips.

[0033] Specifically, an air guide frame 13 is fixedly connected to the air outlet 12. The air guide frame 13 is arranged opposite to the hook 8. The air outlet 12 is used to guide the airflow.

[0034] Specifically, a sealing door 14 that communicates with the box body 1 is sway-connected to the side wall of the box body 1. One end of the sealing door 14 is fixed to the box body 1 by a buckle. By opening the sealing door 14, personnel can take out the dovetail clip and replace it.

[0035] Specifically, an air outlet pipe 15 is fixedly connected to the housing 1, and a manual valve 16 is fixedly connected to the air outlet pipe 15. By opening the manual valve 16, the airflow inside the housing 1 can be discharged to the outside, thereby realizing the circulation of airflow inside the housing 1.

[0036] The working principle of this utility model is as follows: Alternating spraying and drying of the dovetail clips is achieved through two sets of L-shaped transmission components 3 within the housing 1. Initially, the moving seat 5 slides along the housing 1 under the push of an electric push rod, stopping when it contacts the buffer sponge 18 of the L-shaped limiting plate 17. At this time, the rotating disk 6, driven by a motor, rotates the hook 8, causing the suspended dovetail clips to rotate uniformly below the spray head 2. Paint is then transported to the spray head 2 through the inlet pipe for uniform spraying.

[0037] After the painted conveyor 3 is reset, the cylinder pushes the sealing plate 7 to isolate the space of the housing 1, and another set of conveyor 3 moves synchronously to the painting station. The isolated painted dovetail clips enter the drying stage: the fan 9 pressurizes air into the air inlet pipe 10 with built-in heating wire 11, and the hot airflow is precisely blown onto the rotating hook 8 through the air guide frame 13, so that the paint film on the surface of the dovetail clips can be cured quickly. The sealed door 14 on the side wall of the housing 1 facilitates the loading and unloading of workpieces, and the bottom air outlet pipe 15, together with the manual valve 16, realizes the exhaust gas discharge and air circulation.

[0038] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
