Description

Technical Field

[0001] This utility model relates to the field of powder coating, and in particular to a powder coating room for a wire basket. Background Technology

[0002] Metal mesh baskets offer numerous advantages, including breathability, lightweight design, easy visibility, and easy cleaning, making them widely used in various fields such as industry, home furnishings, medical devices, and food processing. However, metal mesh baskets are prone to rusting in humid environments, posing a risk of contamination to items in contact with them. To prevent rusting, the most common process is dip-coating. While dip-coating ensures a full coating of plastic to the basket surface, preventing rust, it has drawbacks such as a thick coating affecting basket dimensions and low production efficiency, hindering large-scale, precision production.

[0003] Traditional single-nozzle powder coating processes for wire mesh baskets are insufficient because the baskets have complex structures such as numerous meshes, gaps, and weld points. A single nozzle cannot cover these areas, and repeated spraying wastes powder, reducing production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a powder coating booth for wire mesh baskets, which solves the problem of incomplete powder coating in areas such as the mesh, gaps, and weld points of the wire mesh baskets.

[0005] This utility model provides a powder coating booth for a wire mesh basket, including a powder coating booth, powder coating machines on both sides of the powder coating booth, and a powder recycling bin on one side of the powder coating booth. The impeller of the powder recycling bin is located inside the powder coating booth, and the body of the powder recycling bin extends to the outside and is connected to a recycling device. The key feature is that a channel is opened on the top surface of the powder coating booth, a track frame is installed on the channel, and a suspension frame is installed under the track frame. The suspension frame can circulate along the track frame. Multiple nozzles are arranged opposite each other inside the powder coating booth. A powder conduit is installed at the tail of the nozzle. The other end of the powder conduit is connected to the powder coating machine. The powder conduit guides the powder from the powder coating machine into the nozzle and sprays it out. The nozzle is also equipped with a nozzle direction control mechanism.

[0006] Furthermore, the nozzle direction control mechanism includes a support lug located below the nozzle, with a through hole on the lug and a pin in the through hole. The pin passes through both ends of the lug and is fixed to a bracket. The bracket is U-shaped, and the lug and pin are in the U-shaped opening of the bracket. The lug can rotate around the pin in the vertical direction. A control line is provided at the end of the nozzle, and the other end of the control line extends to the outside of the powder coating booth and connects to the control cabinet.

[0007] Furthermore, each nozzle corresponds to a control line, and each control line has a separate control panel on the control cabinet. The control panel can be used to control the nozzle to rotate vertically around the pin.

[0008] Furthermore, the nozzle rotates around the pin in the vertical direction at an angle ranging from -60° to 60°.

[0009] Furthermore, an observation window is installed above the control cabinet.

[0010] Optionally, the support is fixedly connected to the slider, the slider is set on the sliding mechanism, the slider can slide left and right in the horizontal direction on the sliding mechanism, and the actuator of the sliding mechanism is connected to the control cabinet through electrical lines and assigned to the control panel of the corresponding nozzle.

[0011] Furthermore, the slider can move left and right in the horizontal direction within a range of 0-15cm.

[0012] Optionally, the nozzle is equipped with a control device for switching the nozzle on and off. The actuator of the control device is connected to the control cabinet via electrical wiring and assigned to the control panel of the corresponding nozzle. The opening and closing of the corresponding nozzle can be controlled through the control panel.

[0013] This utility model discloses a powder coating booth for wire mesh baskets. Taking advantage of the complex surface structure of wire mesh baskets, it employs multiple nozzles arranged in opposite directions for powder coating. The number of nozzles that can be opened can be selected according to the size and structure of different wire mesh baskets, and the horizontal position and vertical angle of the nozzles can be adjusted to control the distribution of powder coating, increase the powder coating concentration in the wire mesh basket and the surrounding air, and enable the powder coating to fully cover the mesh, gaps, or weld points of the wire mesh basket, thereby improving the powder coating effect and efficiency.

[0023] like Figure 1-3As shown, this utility model discloses a wire mesh basket powder coating booth, including a powder coating booth 1. Powder coating machines 2 are installed on both sides of the booth 1, providing powder coating material. Each powder coating machine 2 is equipped with a pressure control device to control the air pressure of the powder coating material. A powder recycling bin 3 is installed on one side of the booth 1, with its impeller located inside the booth 1 and extending to the outside, connecting to a recycling device. The booth 1 has openings at both ends and a channel on its top surface. A track frame 6 is installed on the channel, circumferentially surrounding the booth 1 and the curing oven (not shown in the figure). A suspension frame 7 is installed below the track frame 6, with its lower end inside the booth 1. The track frame 6 is electrically driven; when the power is turned on, the suspension frame 7 circulates along the track frame 6. Before powder coating, the prepared wire mesh basket is suspended on the suspension frame 7, and the basket circulates along the track into the booth 1. After powder coating, it enters the baking and curing process.

[0024] The powder coating booth 1 is equipped with nozzles 8, and a powder conduit 10 is installed at the tail end of the nozzles 8. The other end of the powder conduit 10 is connected to the powder coating machine 2. The powder conduit 10 guides the electrostatically charged compressed air and powder mixture from the powder coating machine 2 into the tail end of the nozzles 8, from where it is sprayed out from the head of the nozzles 8. To ensure the coverage effect of a single spray, such as Figure 2 As shown, this utility model has multiple nozzles 8 on both sides of the powder coating chamber 1, and the nozzles 8 are arranged in a matrix. The nozzles 8 on both sides spray powder at the same time, forming a relatively dense powder distribution around the basket. This powder can easily be adsorbed onto the mesh, gaps, or weld points of the basket, ensuring that all parts of the basket are covered with powder.

[0025] To further control the distribution range of the powder coating and enhance the powder coating effect, a nozzle direction control mechanism is also provided on the nozzle (8). The direction control mechanism includes a support lug 9 provided under the nozzle 8. A through hole is provided on the support lug 9, and a pin 12 is provided in the through hole. The pin 12 passes through both ends of the support lug 9 and is fixed on the bracket 13. The bracket 13 is U-shaped. The support lug 9 and the pin 12 are in the U-shaped opening of the bracket 13. The support lug 9 can rotate around the pin 12 in the vertical direction. The rotation angle range is -60° to 60°. The powder coating direction changes with the rotation of the nozzle 8. A support base 12 is provided at the bottom of the bracket 13. The support base 12 is fixed on the inner wall of the powder coating chamber 1. A control line 11 is provided at the end of the nozzle 8. The other end of the control line 11 extends to the outside of the powder coating chamber 1 and is connected to the control cabinet 5 through an electrical circuit. Each nozzle 8 control line 11 has a corresponding control panel on the control cabinet 5. Each control panel can adjust the direction of the corresponding nozzle 8 through the control line 11. An observation window 4 is provided above the control cabinet 5. The distribution of plastic powder around the mesh basket can be observed through the observation window 4, so as to adjust the direction of the nozzle 8.

[0026] Figure 4This is the second embodiment of the present invention. Unlike the first embodiment, the support 12 is not fixed to the inner wall of the powder coating booth 1. In the second embodiment, the support 12 is fixedly connected to the slider 15, which is mounted on the sliding mechanism 16. The slider 15 can slide horizontally left and right on the sliding mechanism 16. The sliding mechanism 16 is a conventional, controllable, power-driven sliding mechanism, which may be a lead screw slide or a rack and pinion mechanism. The actuator of the sliding mechanism 16 is connected to the control cabinet 5 via electrical wiring and assigned to the control panel of the corresponding nozzle 8. The control panel of the control cabinet 5 can control the slider 15 on the sliding mechanism 16 to move horizontally left and right. The movement range of the slider 15 is 0-15cm. The control panel can also adjust the direction of the nozzle 8.

[0027] To further facilitate the control of nozzle 8, a control valve (not shown in the figure) is provided on nozzle 8. The actuator of the control device is connected to the control cabinet 5 through electrical lines and assigned to the control panel of the corresponding nozzle 8. The control panel can control the opening and closing of the corresponding nozzle 8, the horizontal position of nozzle 8 and the angle of nozzle 8 in the vertical plane.

[0028] In use, turn on the powder coating machine 2, suspend the basket to be powder coated on the hanging frame 7, turn on the power to move the hanging frame 7 and the basket on the track frame 6. When the basket moves to the middle of the multiple sets of nozzles 8 arranged opposite each other, select the nozzle 8 to be used according to the size of the basket via the control panel on the control cabinet 5. According to the size and structure of the basket, control the sliding mechanism 16 to move left and right via the control panel on the control cabinet 5 to adjust the horizontal position of the nozzle 8; and adjust the vertical angle of the nozzle 8 so that the plastic powder sprayed by the nozzle 8 forms a matching plastic powder distribution area at the basket, and the plastic powder is adsorbed onto the surface of the basket. The hanging frame 7 continues to move to transport the basket to the curing oven for baking and curing.

[0029] This utility model discloses a powder coating booth for wire mesh baskets. Taking advantage of the complex surface structure of wire mesh baskets, it employs multiple nozzles arranged in a relatively opposite manner for powder coating. The number of nozzles that can be opened can be selected according to the size and structure of different wire mesh baskets, and the horizontal position and vertical angle of the nozzles can be adjusted to control the distribution of powder coating, increase the powder coating concentration in and around the wire mesh basket, and ensure that the powder coating fully covers the mesh, gaps, or weld points of the wire mesh basket, thereby improving the powder coating effect and efficiency.
