Description

Technical Field

[0001] This utility model relates to the field of powder coating bonding equipment technology, specifically a thermosetting powder coating bonding device. Background Technology

[0002] Thermosetting powder coatings are generally composed of resin, curing agent, pigment, filler, and additives. They use thermosetting resin as the film-forming substance, add a curing agent to initiate a cross-linking reaction, and then heat to form a hard coating. They have excellent decorative properties, and because the low molecular weight prepolymer can form a network of cross-linked macromolecules after curing, they also have good corrosion resistance and mechanical properties. Powder coating bonding, also known as thermal bonding technology, involves bonding metallic pigment particles to powder coating particles at a certain temperature to create a coating with a metallic effect.

[0003] Chinese patent publication number "CN214810439U" discloses "a powder coating bonding device, including a first feeding mechanism, a rotatable second feeding mechanism, a first mixing mechanism, a second mixing mechanism, and a control module. The first mixing mechanism includes a first inlet, a second inlet, a first electrically controlled valve, and a stirring mechanism. The stirring mechanism includes several blades, and a third heating element is provided on both the upper and lower surfaces of the blades. A fourth heating element is provided on the inner wall of the first mixing mechanism. The first feeding mechanism is provided with a first heating element, and the second feeding mechanism is provided with a second heating element. The second mixing mechanism includes a third inlet, a second electrically controlled valve, and a slitting blade. The slitting blade is evenly distributed on the inner wall of the second mixing mechanism, and a fifth heating element is provided on the inner wall of the second mixing mechanism." This patent can achieve precise temperature control, improve product uniformity, and increase production capacity. However, this patent cannot break down the raw materials of the powder coating. The raw materials of the powder coating are prone to clumping during storage, and clumped raw materials will affect the mixing uniformity, thereby affecting the final quality of the coating. Therefore, we propose a thermosetting powder coating bonding device. Utility Model Content

[0004] The purpose of this invention is to provide a thermosetting powder coating bonding device to solve the problem mentioned in the background art that the patent cannot crush the raw materials of the powder coating, wherein the raw materials of the powder coating are prone to agglomeration during storage, and the agglomerated raw materials will affect the mixing uniformity and thus affect the final quality of the coating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermosetting powder coating bonding device, comprising a tank, a feeding box, and a frame. The feeding box is fixedly connected to the upper side of the left side wall of the tank, and the frame is fixedly connected to the top of the tank. A metal screen is fixedly connected to the lower side of the inner side walls of the feeding box. A guide rail groove is provided on the rear side wall of the inner cavity of the feeding box. A linear motor is slidably connected to the inner cavity of the guide rail groove. A mounting plate is fixedly connected to the front side wall of the linear motor. A roller frame is fixedly connected to the bottom of the mounting plate. A crushing roller is rotatably connected between the front and rear side walls of the inner cavity of the roller frame. Telescopic rods are fixedly connected to the left and right side walls of the roller frame. A spring is sleeved on the outer side wall of the telescopic rod, and a scraper is fixedly connected to the end of the telescopic rod.

[0006] As a further description of the above technical solution:

[0007] A heating plate is fixedly connected to the inner wall of the tank, and a discharge pipe is fixedly connected to the bottom of the tank. A solenoid valve is fixedly connected to the middle of the outer wall of the discharge pipe via a flange.

[0008] As a further description of the above technical solution:

[0009] The top of the inner cavity of the frame is provided with a sliding groove, and a first motor is fixedly connected to the upper side of the right side wall of the frame. A bidirectional lead screw is fixedly connected to the end of the power output shaft of the first motor. The end of the bidirectional lead screw passes through the frame and extends into the inner cavity of the sliding groove.

[0010] As a further description of the above technical solution:

[0011] The outer side wall of the bidirectional lead screw is screwed with sliders on both the left and right sides. The bottom of the slider is rotatably connected to a connecting rod, and the end of the connecting rod is rotatably connected to a lifting plate.

[0012] As a further description of the above technical solution:

[0013] A second motor is fixedly connected to the bottom center of the lifting plate. The power output shaft of the second motor is fixedly connected to a rotating shaft. The end of the rotating shaft passes through the tank and extends into the inner cavity of the tank. A bearing is sleeved on the outer wall of the rotating shaft.

The ends of the horizontal rods are fixedly connected to the left and right side walls of the collar.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This thermosetting powder coating bonding device uses a metal screen to screen the raw materials, leaving the agglomerated materials on the screen. A linear motor then drives the mounting plate to move left and right, causing the crushing roller to roll on the metal screen. The crushing roller then crushes the agglomerated raw materials, thereby eliminating the agglomerates. At the same time, a scraper moves with the roller frame, scraping the surface of the metal screen to prevent clogging. This allows the device to eliminate agglomerates and improve the bonding effect.

[0018] 2. This thermosetting powder coating bonding device uses a second motor to drive a rotating shaft, which in turn drives a stirring rod to agitate the powder coating. Then, a first motor drives a bidirectional lead screw, which in turn moves a slider. The slider then moves a connecting rod, causing it to push and pull a lifting plate. The lifting plate, in turn, drives a second motor to move up and down, causing the rotating shaft to move the stirring rod up and down. This allows the stirring rod to agitate the powder coating at different locations within the container, improving the agitation effect. Simultaneously, the vertical rod, horizontal rod, collar, and bearings support the rotating shaft, ensuring stability during its up-and-down movement. This enhances the agitation and bonding effect of the device. Attached Figure Description

A double-acting screw 330 is fixedly connected to the end of the power output shaft of the first motor 320. The end of the double-acting screw 330 passes through the frame 300 and extends into the inner cavity of the slide groove 310. The left side of the outer wall of the double-acting screw 330... Slider blocks 340 are screwed onto both sides. A connecting rod 350 is rotatably connected to the bottom of the slider 340. A lifting plate 360 ​​is rotatably connected to the end of the connecting rod 350. A second motor 370 is fixedly connected to the bottom center of the lifting plate 360. A rotating shaft 380 is fixedly connected to the end of the power output shaft of the second motor 370. The end of the rotating shaft 380 penetrates the tank 100 and extends into the inner cavity of the tank 100. A bearing 381 is sleeved on the outer wall of the rotating shaft 380. A collar 382 is sleeved on the outer wall of the bearing 381. A stirring rod 390 is fixedly connected to the outer wall of the rotating shaft 380. Alternating with bearings 381, vertical rods 361 are fixedly connected to the left and right sides of the bottom of the lifting plate 360. The ends of the vertical rods 361 penetrate the tank body 100 and extend into the inner cavity of the tank body 100. Horizontal rods 362 are fixedly connected to the outer walls of the vertical rods 361, and the ends of the horizontal rods 362 are fixedly connected to the left and right side walls of the collar 382.

Agglomerated raw materials remain on the metal screen 210. At this point, the linear motor 230 drives the mounting plate 240 to move left and right, causing the crushing roller 260 to roll on the metal screen 210, thereby crushing the agglomerated raw materials and eliminating agglomeration. Simultaneously, the scraper 290 moves with the roller frame 250, scraping the surface of the metal screen 210. Then, the heating plate 110 is activated to heat the raw materials, and then the second motor... Motor 370 drives the rotating shaft 380 to rotate, which in turn drives the stirring rod 390 to rotate and stir the raw materials. Then, the first motor 320 drives the double-ended lead screw 330 to rotate, which in turn drives the slider 340 to move. The slider 340 then drives the connecting rod 350 to move, which pushes and pulls the lifting plate 360. The lifting plate 360 ​​then drives the second motor 370 to move up and down, which in turn drives the rotating shaft 380 to move the stirring rod 390 up and down. This allows the stirring rod 390 to stir the powder coating at different positions within the tank 100 while simultaneously rotating and stirring. Finally, when bonding is complete, the solenoid valve 130 is opened, allowing the discharge pipe 120 to discharge the powder coating.
