Although this reactor can add powder from the feed port into the reactor body during the mixing process, manual feeding or external equipment is required for auxiliary feeding. The former is more troublesome, and the latter has adaptation problems.

[0006] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] A reactor for producing high temperature resistant powder coatings, such as Figure 1-Figure 4 As shown, it includes a kettle body 1, a motor 2 is fixedly connected to the kettle body 1, a telescopic rod 3 is fixedly connected to the output shaft of the motor 2, and a plurality of stirring rods 4 are fixedly connected to the telescopic end of the telescopic rod 3. The kettle body 1 is provided with a discharging mechanism for discharging materials in stages. When powder coatings need to be mixed, one kind of powder is first added to the kettle body 1, and then the remaining powders are put into the discharging mechanism, and then the motor 2 is turned on. The rotation of the output shaft of the motor 2 will drive the telescopic rod 3 and the stirring rod 4 to rotate. When the telescopic rod 3 rotates, the discharging mechanism will be triggered to discharge materials continuously and slowly, so that the materials can be fed continuously and slowly during the mixing process to avoid local accumulation of similar powders, thereby improving the uniformity and stability of the powder coatings.

[0024] like Figure 1-Figure 4 As shown, the discharge mechanism includes a sleeve 5, two sliding rods 6, two billiard balls 7 and two placement components for placing powder, the placement component includes a placement tube 9, a cover plate 10 and a plurality of baffles 11, the placement tube 9 is fixedly connected to the top side of the kettle body 1 and is conductive with the outside world, the placement tube 9 and the inner cavity of the kettle body 1 are conductive with each other, because the discharge port of the placement tube 9 is small and the powder itself has friction, the powder can be retained in the placement tube 9, the cover plate 10 is detachably connected to the upper side of the kettle body 1, when the cover plate 10 is installed on the kettle body 1, the upper side of the placement tube 9 is blocked, the baffle 11 is fixedly connected to the side of the placement tube 9 away from the cover plate 10, which can block the powder to prevent the powder from flowing too fast, when the billiard balls 7 contact the placement tube 9, the spring 8 is in a compressed state, the sleeve 5 is fixedly connected to the fixed end of the telescopic rod 3, the two sliding rods 6 are slidably connected to the two ends of the sleeve 5 and are connected by a spring 8, the placement component is arranged on the top side of the kettle body 1,

[0025] like Figure 1-Figure 4 As shown, when the telescopic rod 3 rotates, the sleeve 5, the sliding rod 6 and the billiard ball 7 will be driven to rotate. Thereafter, the billiard ball 7 will hit the placement tube 9, causing the placement tube 9 to vibrate, thereby causing the powder in the placement tube 9 to fall out of the placement tube 9. Then the telescopic rod 3 continues to rotate, and the two sliding rods 6 will approach each other. At this time, the spring 8 is in a compressed state, and the billiard ball 7 can pass through the placement tube 9 without being blocked by the placement tube 9. In this way, the material can be discharged continuously and slowly by reciprocating.

[0026] like Figure 2-Figure 3 As shown, an inclined block 12 is fixedly connected to the upper side of the blocking rod 11, which can prevent powder from staying on the blocking rod 11, thereby avoiding powder waste.

[0027] like Figure 2-Figure 3 As shown, a partition 13 is detachably connected to the placement barrel 9, and the partition 13 fits in contact with the inclined block 12 on the same side. When more kinds of powder need to be added, the partition 13 can be installed in the placement barrel 9, thereby eliminating the need for manual secondary feeding.

[0028] like Figure 2 、 Figure 4 As shown, a plurality of positioning frames 14 are fixedly connected to the inner wall of the kettle body 1, and a plurality of protrusions 15 are fixedly connected to the positioning frames 14. When the billiard ball 7 contacts the protrusion 15, the spring 8 is in a compressed state. When the telescopic rod 3 rotates, the billiard ball 7 contacts the plurality of protrusions 15 in sequence, and vibration occurs at this time. Subsequently, the vibration is transmitted from the positioning frame 14 to the kettle body 1, causing the powder adhering to the inside of the kettle body 1 to fall off, thereby making the powder mixing more uniform.

[0029] like Figure 2-Figure 3 As shown, a positioning rod 16 is fixedly connected to the outer wall of the telescopic end of the telescopic rod 3, and an undulating block 17 is fixedly connected to the inner wall of the kettle body 1. When the positioning rod 16 contacts the undulating block 17, the telescopic end of the telescopic rod 3 moves toward the fixed end. When the telescopic rod 3 rotates, the positioning rod 16 is driven to rotate. When the positioning rod 16 contacts the uphill section of the undulating block 17, the stirring rod 4 is lifted. At this time, the powder on the upper side of the stirring rod 4 is also lifted. When the positioning rod 16 contacts the downhill section of the undulating block 17, the stirring rod 4 drops due to gravity. At this time, the powder on the lower side of the stirring rod 4 is pushed to both sides of the stirring rod 4 by the stirring rod 4, so that the powder rolls up and down during mixing, so that the mixing can be made more uniform.

[0030] like Figure 2 As shown, the bottom side of the lowest stirring rod 4 fits with the inner bottom side of the kettle body 1, which can avoid the powder being hidden between the bottom side of the lowest stirring rod 4 and the inner bottom side of the kettle body 1 and unable to be mixed, thereby causing uneven mixing.

[0031] Working principle: When powder coating mixing is required, first add one kind of powder into the kettle body 1, and then put the rest of the powder into the placement barrel 9, and then turn on the motor 2. The rotation of the output shaft of the motor 2 will drive the telescopic rod 3 and the stirring rod 4 to rotate. When the telescopic rod 3 rotates, it will drive the sleeve 5, the sliding rod 6 and the billiard ball 7 to rotate. After that, the billiard ball 7 will hit the placement barrel 9, causing the placement barrel 9 to vibrate, so that the powder in the placement barrel 9 will fall out of the placement barrel 9, and then the telescopic rod 3 continues to rotate, and the two sliding rods 6 will approach each other. At this time, the spring 8 is in a compressed state, and the billiard ball 7 can pass through the placement barrel 9 without being blocked by the placement barrel 9. In this reciprocating manner, continuous and slow discharge can be carried out, and When the telescopic rod 3 rotates, the billiard ball 7 will contact several protrusions 15 in sequence, and vibration will occur at this time. The vibration will then be transmitted from the positioning frame 14 to the kettle body 1, causing the powder adhering to the inside of the kettle body 1 to fall off, and its rotation will also drive the positioning rod 16 to rotate. When the positioning rod 16 contacts the uphill section of the undulating block 17, the stirring rod 4 will be lifted. At this time, the powder on the upper side of the stirring rod 4 will also be lifted. When the positioning rod 16 contacts the downhill section of the undulating block 17, the stirring rod 4 will drop due to gravity. At this time, the powder on the lower side of the stirring rod 4 will be pushed to both sides of the stirring rod 4 by the stirring rod 4, causing the powder to roll up and down during mixing, thereby making the powder mixing more uniform.

[0032] This method can continue to slowly add materials during the mixing process to avoid local accumulation of similar powders, thereby improving the uniformity and stability of the powder coating, and can further make the powder coating more evenly mixed during the mixing process.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
