Resin powder screening device for powder coating production

Abstract

This utility model relates to the field of powder coating production technology and discloses a resin powder sieving device for powder coating production. A sieving frame is fixedly installed inside the mounting frame, and the number of sieving frames is three sets. Support columns are horizontally fixedly installed on both sides of the outside of the mounting frame, and a transmission frame is vertically fixedly installed between the outer sides of the support columns. A connecting frame is fixedly installed on the top of the outside of the mounting frame. In this utility model, when the servo motor drives the actuating lever to rotate, it can drive multiple sets of second transmission rods located at the bottom of the sieving frame to rotate synchronously. Combined with the connecting transmission action of the second transmission rods, it can drive the striking plate to rotate synchronously at the bottom of the sieving frame, striking it from the bottom. This causes the sieving frame itself to vibrate, discharging the powder particles clogging the mesh, thus preventing the accumulation and clogging of powder materials and avoiding affecting the sieving efficiency.

Description

Technical Field

[0001] This utility model applies to the field of powder coating production technology, and in particular relates to a resin powder screening device for powder coating production. Background Technology

[0002] Currently, resin powder is a finely granular solid material made from high-molecular polymers through specific processes. Due to its excellent physicochemical properties, it is widely used in coating production. The particle size distribution of resin coatings directly affects their leveling properties, powder application rate, and film thickness uniformity. Overly coarse particles will result in a rough coating surface and poor leveling properties, while overly fine particles may be difficult to deposit due to weak electrostatic adsorption, and may even pose a dust explosion risk. Therefore, when using resin powder raw materials to produce powder coatings, sieving is often required.

[0003] However, in current resin powder raw material sieving processes, as the resin powder particles pass through the mesh of the screen, they not only become stuck inside the stationary mesh during their downward movement, affecting subsequent powder particle sieving efficiency, but also accumulate on the screen surface. To improve sieving efficiency, the operator must repeatedly agitate the material to allow the accumulated material to move downwards quickly. This cumbersome process negatively impacts the sieving efficiency of the powder material. Therefore, we propose a resin powder sieving device for powder coating production. Utility Model Content

[0004] The main objective of this invention is to provide a resin powder screening device for powder coating production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A resin powder sieving device for powder coating production includes an installation frame, a sieving screen frame fixedly installed inside the installation frame, and the number of sieving screen frames is three sets. Support columns are fixedly installed horizontally on both sides of the outside of the installation frame, a transmission frame is fixedly installed vertically between the outer sides of the support columns, a connecting frame is fixedly installed on the top of the outside of the installation frame, and a hollow frame is fixedly installed on the top of the outside of the connecting frame. The hollow frame is equipped with a bidirectional drive mechanism, and the connecting frame is equipped with a vertically rotating actuating mechanism at its upper end, which is connected to the bidirectional drive mechanism. The transmission frame is equipped with a transmission mechanism, which is connected to the bidirectional drive mechanism.

[0006] As an optional solution to the technical solution of this application, the bidirectional drive mechanism includes a first transmission bevel gear and a first follower bevel gear. A rotating rod is vertically rotatably mounted on the middle of the inner side of the connecting frame via a bearing, and the rotating rod is inserted into the middle of the screening frame via a bearing. A first transmission rod is horizontally rotatably mounted on both sides of the connecting frame via a bearing, and the top of the side of the first transmission rod extends rotatably from the inside of the hollow frame to the top of the transmission frame via a bearing. The top of the side of the first transmission rod is fixedly sleeved with a first follower bevel gear. A servo motor is fixedly mounted on the middle of the top of the hollow frame, and the bottom of the servo motor drive shaft is fixedly connected to the top of the rotating rod. The top of the rotating rod is fixedly sleeved with a first transmission bevel gear, and the outer sides of the first transmission bevel gear mesh with the outer sides of two sets of first follower bevel gears respectively. A second transmission bevel gear is fixedly sleeved on the top of the side of each first transmission rod. A fixed rod is vertically rotatably mounted on the top of the inner side of the transmission frame via a bearing, and the top of the fixed rod is fixedly sleeved with a second follower bevel gear, and the outer sides of the second follower bevel gear mesh with the outer sides of the second transmission bevel gear.

[0007] As an optional solution to the technical solution of this application, each of the fixed rods is vertically fixedly installed with an installation rod at its bottom. A third transmission bevel gear is fixedly sleeved on the outside of each of the installation rods. A second transmission rod is horizontally rotatably installed on the side of the transmission frame via a bearing, and the top of the side of the second transmission rod is rotatably installed inside the installation frame via a bearing. A third follower bevel gear is fixedly sleeved on the side of the second transmission rod, and the outer sides of the third transmission bevel gear and the third follower bevel gear mesh with each other. Fixed sleeves are fixedly sleeved at both ends of the side of the second transmission rod. A beater plate is fixedly installed on the outside of the fixed sleeve, and the beater plate is located below the bottom of the screening frame.

[0008] By adopting the above technical solution, under the connecting transmission action of the second transmission rod and the meshing transmission action of the third transmission bevel gear and the third follower bevel gear, the second transmission rod and the patting soft plate can be driven to rotate synchronously with the rotation of the rotating rod, and the bottom surface of the screening screen frame can be patted and vibrated.

[0009] As an optional solution to the technical solution of this application, a fixed frame is fixedly sleeved on the outside of the rotating rod, and a connecting plate is fixedly installed on all four sides of the outside of the fixed frame. A toggle rod is vertically fixedly installed at the bottom of each connecting plate, and the number of toggle rods is several sets.

[0010] By adopting the above technical solution, the rotating rod can drive the agitator to rotate on the surface of the screening frame when the rotating rod rotates, thereby agitating and dispersing the powder material accumulated on the surface.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This application discloses a resin powder sieving device for powder coating production. A sieving frame is installed inside the mounting frame, and a connecting frame and a transmission frame are installed outside the sieving frame. When a servo motor operates, it drives a rotating rod to rotate. Combined with the driving action of the rotating rod, this synchronously drives the connecting plate and the actuating rod to rotate on top of the sieving frame. This allows the actuating rod to disperse the powder material accumulated on the surface of the sieving frame, preventing powder buildup and ensuring efficient sieving. Simultaneously, under the meshing transmission action of the first transmission bevel gear and the first follower bevel gear, the rotating rod, when driven to rotate, synchronously drives the first transmission rods on both sides inside the connecting frame to rotate, thereby driving the second transmission... After the bevel teeth rotate at the top inside the transmission frame, under the meshing transmission action of the second transmission bevel teeth and the second follower bevel teeth, they can drive the fixed rod and the multiple sets of third transmission bevel teeth sleeved on the bottom outer side to rotate. Synchronously, under the meshing transmission action of the third transmission bevel teeth and the third follower bevel teeth, when the servo motor drives the rotating lever, it can drive the multiple sets of second transmission rods located at the bottom of the screening frame to rotate synchronously. Under the connecting transmission action of the second transmission rods, it can drive the slapping soft plate to rotate synchronously at the bottom of the screening frame and strike it from the bottom. This causes the screening frame to generate vibration force, and at the same time, it vibrates and discharges the powder particles blocking the mesh, avoiding the accumulation and blockage of powder materials, which would affect the screening efficiency of powder materials.

[0014] like Figure 1-3As shown, this utility model provides a technical solution: a resin powder screening device for powder coating production, wherein a screening frame 11 is fixedly installed inside the mounting frame 1, and the number of screening frames 11 is three sets; support columns 12 are fixedly installed horizontally on both sides of the outside of the mounting frame 1; a transmission frame 14 is fixedly installed vertically between the outer sides of the support columns 12; a connecting frame 13 is fixedly installed on the top of the outside of the mounting frame 1; and a hollow frame 15 is fixedly installed on the top of the outside of the connecting frame 13.

[0015] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a rotating rod 2 is vertically mounted on the inner middle of the connecting frame 13 via a bearing, and the rotating rod 2 is inserted through the bearing into the middle of the screening frame 11. The first transmission rod 26 is horizontally mounted on both sides of the connecting frame 13 via bearings, and the top of the side of the first transmission rod 26 extends from the inside of the hollow frame 15 to the top of the transmission frame 14 via a bearing. The top of the side of the first transmission rod 26 is fixedly sleeved with the first follower bevel gear 27. A servo motor 24 is fixedly mounted on the top middle of the hollow frame 15, and the bottom of the transmission shaft of the servo motor 24 is fixedly connected to the top of the rotating rod 2. The top of the rotating rod 2 is fixedly sleeved with the first transmission bevel gear 25, and the outer sides of the first transmission bevel gear 25 respectively mesh with the outer sides of the two sets of first follower bevel gears 27.

[0016] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fixed frame 21 is fixedly sleeved on the outside of the rotating rod 2. Connecting plates 22 are fixedly installed on all four sides of the fixed frame 21. A toggle rod 23 is vertically fixedly installed at the bottom of each connecting plate 22, and there are several sets of toggle rods 23.

[0017] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a second transmission bevel tooth 3 is fixedly sleeved on the top side of each first transmission rod 26. A fixed rod 31 is vertically rotatably mounted on the top side of the transmission frame 14 via a bearing. A second follower bevel tooth 32 is fixedly sleeved on the top of the fixed rod 31, and the second follower bevel tooth 32 meshes with the outer sides of the second transmission bevel tooth 3.

[0018] In some technical solutions (through Figure 1 , Figure 2 and Figure 3As shown), each fixed rod 31 has a vertically fixed mounting rod 33 at its bottom. Each mounting rod 33 is externally fixedly sleeved with a third transmission bevel gear 34. The side of the transmission frame 14 is horizontally rotatably mounted with a second transmission rod 35 via a bearing. The top of the side of the second transmission rod 35 is rotatably mounted inside the mounting frame 1 via a bearing. The side of the second transmission rod 35 is fixedly sleeved with a third follower bevel gear 36. The outer sides of the third transmission bevel gear 34 and the third follower bevel gear 36 mesh with each other. Both ends of the side of the second transmission rod 35 are fixedly sleeved with fixed sleeves 4. A beater plate 41 is fixedly mounted on the outer side of the fixed sleeve 4. The beater plate 41 is located below the bottom of the screening frame 11.

[0019] During operation, when sieving resin powder raw materials is required, the servo motor 24 is turned on via an external control switch, causing it to rotate. This rotation drives the rotating rod 2 and the first transmission bevel gear 25 fitted on its surface to rotate. Subsequently, under the connecting transmission action of the rotating rod 2, the connecting plate 22 and the actuating rod 23 fitted on its outer side can be driven to rotate synchronously on the surface of the sieving frame 11. This allows the actuating rod 23 to rotate and disperse the powder material accumulated on the surface of the sieving frame 11 while rotating, preventing the powder material from agglomerating and affecting the sieving efficiency. At the same time, under the connecting transmission action of the rotating rod 2 and the meshing transmission action of the first transmission bevel gear 25 and the first follower bevel gear 27, the first transmission rod 26 can be driven to rotate synchronously on both sides of the connecting frame 13. This synchronously drives the second transmission bevel gear 3 at the top of the side of the first transmission rod 26 to move forward. The rotation of the transmission frame 14 causes the second transmission bevel 3 to rotate at the top inside the transmission frame 14. Under the meshing transmission action of the second transmission bevel 3 and the second follower bevel 32, the fixed rod 31 and the multiple sets of third transmission bevel 34 sleeved on the bottom outer side can rotate. Synchronously, under the meshing transmission action of the third transmission bevel 34 and the third follower bevel 36, when the servo motor 24 drives the toggle lever 23 to rotate, it can drive the multiple sets of second transmission rods 35 located at the bottom of the screening frame 11 to rotate synchronously. Under the connecting transmission action of the second transmission rods 35, the striking plate 41 can rotate synchronously at the bottom of the screening frame 11 and strike it from the bottom. This causes the screening frame 11 to generate vibration force and vibrate out the powder particles blocking the mesh. Then, under the synchronous screening action of the three sets of screening frames 11, the resin powder raw material can be screened.
