Description

Technical Field

[0001] This utility model belongs to the field of automotive water-cooled plate processing technology, specifically a powder reduction device for automotive water-cooled plate powder spraying chamber. Background Technology

[0002] In the powder coating process of automotive water-cooled plates, the powder coating chamber is the key location for powder coating application. However, during the coating process, a large amount of powder coating becomes overspray because it does not fully adhere to the surface of the water-cooled plate. If this overspray is not effectively controlled, it will drift disorderly in the powder coating chamber, causing many problems. First, the drift of overspray will seriously affect the coating quality. The drifted powder may re-adhere to the already coated surface of the water-cooled plate, resulting in uneven coating thickness, spots, particles, and other defects, which will affect the appearance and protective performance of the water-cooled plate. Second, the accumulation of overspray in the powder coating chamber will increase the difficulty of cleaning, reduce the service life of the equipment, and may also pose a health hazard to the operators. In addition, the waste of overspray will increase production costs and reduce production efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a powder reduction device for an automotive water-cooled plate powder coating chamber. This device solves the problem that during the spraying process, a large amount of powder coating becomes oversprayed powder because it does not fully adhere to the surface of the water-cooled plate. This powder then disperses disorderly in the powder coating chamber, and the dispersed powder may re-adhere to the already sprayed surface of the water-cooled plate, resulting in uneven coating thickness. Furthermore, the accumulation of oversprayed powder in the powder coating chamber increases the difficulty of cleaning, reduces the service life of the equipment, and may also pose a health hazard to the operators. In addition, the waste of oversprayed powder increases production costs and reduces production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a powder reduction device for an automotive water-cooled plate powder coating chamber, comprising a powder coating chamber, two powder reduction mechanisms symmetrically arranged on both sides of the powder coating chamber, each powder reduction mechanism comprising two air ducts, both air ducts being fixedly installed on the side of the powder coating chamber, each air duct having several through slots at both ends, an mounting frame fixedly installed between the inner walls of the air ducts, a fan being rotatably connected to the side of the mounting frame facing the inside of the powder coating chamber, a control power supply being fixedly installed on the other side of the mounting frame, the control power supply being connected to the fan, the two powder reduction mechanisms facing each other, several fixing frames being provided on the outer wall of the powder coating chamber, the fixing frames respectively covering the outside of the air ducts, fixing bolts being connected to the four corners of each fixing frame, the fixing frames being connected to the powder coating chamber through the fixing bolts, and a filter plate being movably connected to the opening on the outside of the fixing frame.

[0005] As a further embodiment of this utility model: four fixing mechanisms are provided at the opening on the outside of the fixing frame. Each fixing mechanism includes a baffle, which is fixedly connected to the inner wall of the fixing frame. An L-shaped bracket is fixedly connected to the outer wall of the fixing frame at a position corresponding to the baffle.

[0006] As a further embodiment of this utility model: the protruding part of the L-shaped bracket is threadedly connected to a fixing screw at its center position, a fixing block is fixedly connected to one end of the fixing screw facing the baffle, and a handle is fixedly connected to the other end of the fixing screw.

[0007] As a further embodiment of this utility model: the filter plate is located between the baffle and the fixing block, and the filter plate is fixed in the fixing frame by the fixing block pressing the baffle.

[0008] As a further embodiment of this utility model: two guide plates are symmetrically fixedly connected to the inner wall of the powder spraying chamber near its top. The guide plates are inclined and oriented opposite each other, forming a 30° angle with the vertical horizontal plane.

[0009] As a further embodiment of this utility model: a collection trough is fixedly connected to the center of the bottom of the powder spraying chamber, and a number of collection ports are opened at the top of the collection trough.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This powder reduction device for automotive water-cooled plate powder coating chamber, through the setting of a powder reduction mechanism, generates airflow when the fan in the powder reduction mechanism is driven by the control power supply. The airflow enters the powder coating chamber through the through slots at both ends of the air duct. Since the two powder reduction mechanisms face each other, the generated airflow blows against each other. The pressure at the point where the two airflows meet forms a high-pressure zone, causing the airflow to flow to the area with lower pressure. It flows downward along the guide plate at the top of the powder coating chamber, forming a downward airflow that guides the oversprayed powder to the collection tank at the bottom of the powder coating chamber. This reduces the dispersion of powder in the powder coating chamber, improves the powder reduction effect, reduces powder waste, and avoids the potential health hazards to operators caused by the disorderly dispersion of powder in the powder coating chamber.

[0011] 2. This powder reduction device for the automotive water-cooled plate powder spraying chamber, through the setting of a filter plate and a fixing mechanism, allows airflow to be drawn in from the outside and flow into the powder spraying chamber after passing through the filter plate during the operation of the powder reduction mechanism. The filter plate filters the airflow, reducing the amount of impurities entering the powder spraying chamber. After long-term use, by rotating the handle, the handle drives the fixing screw in the fixing mechanism to move on the L-shaped bracket, which relaxes the pressure of the fixing block on the filter plate or moves the fixing block closer to the baffle, making it easy to remove or fix the filter plate. This makes the installation and removal of the filter plate extremely convenient, facilitates regular maintenance and cleaning of the filter plate, ensures long-term stable operation of the equipment, and reduces the maintenance cost and operation difficulty of the equipment.

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-5 As shown, this utility model provides a technical solution: a powder reduction device for an automotive water-cooled plate powder spraying chamber, including a powder spraying chamber 1. A collection trough 8 is fixedly connected to the center of the bottom of the powder spraying chamber 1. Several collection ports 9 are opened at the top of the collection trough 8. Because of the collection trough 8, after the airflow drives the powder to flow downward, it falls into the collection trough 8, which can effectively collect the oversprayed powder, which is convenient for subsequent recycling and reuse, and improves the powder recycling rate. Two guide plates 7 are symmetrically fixedly connected to the inner wall of the powder spraying chamber 1 near its top. The guide plates 7 are inclined and opposite in direction. The guide plates 7 form a 30° angle with the vertical horizontal plane. Because of the guide plates 7 and the 30° angle design, the airflow can flow smoothly downward along the direction of the guide plates 7 after meeting, instead of forming vortices or turbulence in the powder spraying chamber 1. The downward airflow can effectively guide the oversprayed powder to the bottom of the powder spraying chamber 1, reducing the dispersion of powder in the powder spraying chamber 1. Two powder-reducing mechanisms 2 are symmetrically arranged on both sides of the powder spraying chamber 1. Each powder-reducing mechanism 2 includes two air ducts 201, both of which are fixedly installed on the side of the powder spraying chamber 1. Several through slots 202 are opened at both ends of each air duct 201. A mounting bracket 203 is fixedly installed between the inner walls of the air ducts 201. A fan 204 is rotatably connected to the side of the mounting bracket 203 facing the inside of the powder spraying chamber 1. A control power supply 205 is fixedly installed on the other side of the mounting bracket 203 and connected to the fan 204. The two powder-reducing mechanisms 2 face each other. Because of the powder-reducing mechanisms 2, their opposing arrangement allows the generated airflow to blow against each other. When the two airflows... When the airflows meet, momentum exchange occurs, causing a change in airflow direction. At the same time, the pressure at the point where the airflows meet increases, forming a high-pressure zone. This causes the airflow to flow towards the area with lower pressure, forming a downward airflow. This airflow guiding effect can effectively guide the oversprayed powder to the bottom of the powder spraying chamber 1, reducing the dispersion of powder in the powder spraying chamber 1 and improving the powder reduction effect. The outer wall of the powder spraying chamber 1 is provided with several fixed frames 3, which are respectively covered by the air duct 201. Fixed bolts 4 are connected to the four corners of the fixed frames 3. The fixed frames 3 are connected to the powder spraying chamber 1 through the fixed bolts 4. A filter plate 5 is movably connected to the opening on the outside of the fixed frame 3. Four fixing mechanisms 6 are provided at the opening on the outside of the fixing frame 3. Each fixing mechanism 6 includes a baffle 601, which is fixedly connected to the inner wall of the fixing frame 3. An L-shaped bracket 602 is fixedly connected to the outer wall of the fixing frame 3 at a position corresponding to the baffle 601. A fixing screw 603 is threadedly connected to the protruding part of the L-shaped bracket 602 at its center. A fixing block 604 is fixedly connected to the end of the fixing screw 603 facing the baffle 601. A filter plate 5 is located between the baffle 601 and the fixing block 604. The filter plate 5 is fixed inside the fixing frame 3 by pressing the baffle 601 with the fixing block 604. Because of the filter plate 5, the dust removal mechanism 2 draws in airflow from the outside. After passing through the filter plate 5, the airflow flows into the powder spraying chamber 1. The filter plate 5 filters the airflow into the powder spraying chamber 1, reducing impurities in the airflow entering the powder spraying chamber 1 and preventing impurities in the airflow from entering the powder spraying chamber 1 and adsorbing onto the automotive water-cooling plate, thereby ensuring the coating quality. The other end of the fixing screw 603 is fixedly connected to a handle 605. Because a fixing mechanism 6 is provided, the position of the fixing screw 603 can be adjusted by rotating the handle 605, thereby driving the fixing block 604 to move closer to or away from the baffle 601, realizing the fixing and loosening of the filter plate 5. This design makes the installation and disassembly of the filter plate 5 very convenient and facilitates the maintenance of the filter plate 5.

[0015] The working principle of this utility model is as follows: When using this device, the fans 204 in the two powder-reducing mechanisms 2 are first started. Driven by the control power supply 205, the fans 204 begin to rotate, generating airflow. The airflow passes through the through-slot 202 and enters the powder spraying chamber 1. Since the two powder-reducing mechanisms 2 are facing each other, the airflow generated by the fans 204 will blow against each other. When the two airflows meet, the airflow direction will change, and the pressure at the point where the airflows meet will increase, forming a high-pressure zone. Due to the pressure change, the airflow will flow towards the area with lower pressure. At the top of the powder spraying chamber 1, the airflow will flow downward along the direction of the guide plate 7, forming a downward airflow. The oversprayed powder will eventually fall into the through-slot 202 at the bottom of the powder spraying chamber 1 under the action of the downward airflow. After passing through the collection port 9, the air enters the collection tank 8. During the operation of the two powder reduction mechanisms 2, the filter plate 5 filters the airflow flowing into the powder spraying chamber 1, reducing impurities in the airflow entering the powder spraying chamber 1. After the filter plate 5 has been used for a long time, the fixing screw 603 in the fixing mechanism 6 is rotated by the handle 605. The fixing screw 603 moves on the L-shaped bracket 602, causing the fixing block 604 to relax its pressure on the filter plate 5, so that the filter plate 5 can be removed. After the filter plate 5 is cleaned, the four corners of the filter plate 5 are aligned with the baffles 601 in the four fixing mechanisms 6 respectively. The handle 605 is rotated so that the fixing screw 603 moves the fixing block 604 close to the baffle 601 to fix the filter plate 5, thereby completing the cleaning and installation of the filter plate 5.
