[0022] When in use, the products that need to be coated with powder are conveyed by the first conveyor belt 1, and then the products are conveyed to the third conveyor belt 4. In the process of the third conveyor belt 4 conveying the products, the products are firstly sprinkled with powder by the vibrating powder sprinkling part; then the powder on the surface of the product and the powder on the third conveyor belt 4 is atomized by the powder atomization part; after the product moves to the powder reabsorption part, the excess powder on the surface of the product and in the powder atomization part can be reabsorbed by the powder atomization part, and the products that have completed the powder coating process are conveyed to the second conveyor belt 2 by the third conveyor belt 4.

[0023] In order to ensure the operation of the product conveying part, as an embodiment of the present invention, a chassis 3 is provided on one side of the product conveying part, and the product conveying part includes a third conveyor belt 4 installed on one side of the chassis 3, and a roller 5 for driving the third conveyor belt 4 to move and a guide roller 6 for guiding the third conveyor belt 4 are installed on the chassis 3. A collecting funnel 43 connected to the chassis 3 is provided below the third conveyor belt 4, and a scraper 48 for cleaning the third conveyor belt 4 is connected to the inner side of the collecting funnel 43. A powder collecting box assembly for collecting powder is provided below the collecting funnel 43, and a sorting mechanism for briquetting and sorting the powder is provided in the powder collecting box assembly.

[0024] When in use, the motor arranged in the chassis 3 can drive the roller 5 to rotate, thereby driving the third conveyor belt 4 to move, and the stability of the third conveyor belt 4 can be ensured by the guidance of the guide roller 6; during the operation of the third conveyor belt 4, the scraper rod 48 cleans the outside of the third conveyor belt 4, and the cleaned powder will fall into the powder collecting box assembly, and the powder will be pressed into blocks and stacked through the sorting mechanism; the collecting funnel 43 can collect the powder dropped from the product conveying part.

[0025] In order to facilitate the briquetting process of the powder by the sorting mechanism, as an embodiment of the present invention, a bottom plate 47 connected to the chassis 3 is provided below the powder collecting box assembly, and the powder collecting box assembly includes a back plate 7, and side plates 8 detachably connected to the bottom plate 47 are provided on both sides of the back plate 7, and the back plate 7 is connected to the side plates 8 through a lock, and the sorting mechanism includes a briquetting mechanism arranged between the two groups of side plates 8, and the briquetting mechanism includes a fourth conveyor belt 9 arranged horizontally, and a driving roller 10 and a driven roller 11 rotatably connected to the chassis 3 are provided in the fourth conveyor belt 9, and the driving roller 10 and the driven roller 11 are driven by the fourth conveyor belt. One end of the driving roller 10 is provided with a driving motor for driving the driving roller 10 to rotate, and the driving motor is installed in the chassis 3. The outer side of the fourth conveyor belt 9 is connected to a plurality of groups of positioning blocks 12, and the positioning blocks 12 are each provided with a slide groove 13. A movable plate 14 is slidably connected in the slide groove 13, and a supporting spring 46 is connected between the bottom of the slide groove 13 and the movable plate 14. A wedge-shaped guide plate 15 connected to the bottom plate 47 is provided below the fourth conveyor belt 9. The fourth conveyor belt 9 pushes the powder from the thinner end of the guide plate 15 to the thicker end through the positioning block 12 and the movable plate 14 to press the powder into blocks.

[0026] When in use, the powder falling into the powder collecting box assembly will fall on the guide plate 15, and the driving motor drives the driving roller 10 to rotate, thereby driving the fourth conveyor belt 9 to rotate, and the fourth conveyor belt 9 drives the positioning block 12 and the movable plate 14 to rotate, so that the powder falling on the guide plate 15 is pushed from the thinner end of the guide plate 15 to the thicker end. During the pushing process, the distance between the guide plate 15 and the fourth conveyor belt 9 is reduced, and the movable plate 14 moves into the chute 13, so that the powder is compressed into a block, and moves to one side with the conveyance of the fourth conveyor belt 9. It should be pointed out that the upper surface of the guide plate 15 near one end of the storage frame 16 is horizontally arranged, which can facilitate the briquetting mechanism to squeeze the powder into a block with a flat bottom, so as to facilitate its stacking, and at the same time, it is also convenient for the briquetting mechanism to convey the briquetting powder into the storage frame 16.

[0027] In order to facilitate the storage of the powder after briquetting, as an embodiment of the present invention, the powder collecting box assembly also includes a storage frame 16 arranged between the two groups of side panels 8, and the storage frame 16 is fixedly connected to the back panel 7, and the upper part of the storage frame 16 and the side close to the fourth conveyor belt 9 are both open.

[0028] When in use, the powder compressed into blocks will move to one side of the storage frame 16 as it is transported by the fourth conveyor belt 9, and relying on the open setting of the side of the storage frame 16 close to the fourth conveyor belt 9, the compressed powder can be pushed into the storage frame 16. Subsequently, the user pulls the back panel 7 to pull out the powder stored in the storage frame 16, so as to facilitate subsequent processing.

[0029] In order to facilitate the stacking and storage of the powder after briquetting, as an embodiment of the present invention, the storage frame 16 is provided with upper and lower stacked pallets 17, and a pull rope 18 is connected between adjacent pallets 17. A winding shaft 19 is provided above the storage frame 16, and one end of the winding shaft 19 is rotatably connected to the chassis 3, and the winding shaft 19 is connected to the topmost pallet 17 through a connecting rope 20. The pull rope 18 and the connecting rope 20 are both located on the side of the pallet 17 close to the fourth conveyor belt 9, and at least two groups of sliders 45 are connected to the side of the pallet 17 close to the chassis 3, and the slider 45 is vertically slidably connected to the chassis 3, and the slider 45 is arranged on the side of the push plate close to the fourth conveyor belt 9. An opening 21 corresponding to the stacked pallet 17 is provided at the bottom of the side of the storage frame 16 away from the back plate 7, and a plurality of groups of notches 22 are distributed from top to bottom on the side of the storage frame 16 away from the back plate 7, and the notches 22 correspond to the position of the pallet 17 after the winding shaft 19 completely reels up the connecting rope 20.

[0030] When in use, the connecting rope 20 is rolled up by the winding shaft 19, and the pallets 17 can be pulled up one by one. After a sufficient amount of powder has been piled on the pallet 17, the pallet 17 is pulled up to put the next group of pallets 17 into use, so that the powder after block can be stacked up and down and placed in the storage frame 16; and, after the pallet 17 is fully unfolded and put into use, the user can move the back plate 7 to move the storage frame together with the powder after block, at this time, the pallet 17 passes through the slot 22, and the powder after block is left in the storage frame 16; it should be pointed out that the pull rope 18 and the connecting rope 20 are arranged on one side of the pallet 17, which can avoid hindering the movement of the pallet 17 in the slot 22; similarly, at least two groups of sliders 45 are connected to each group of pallets 17 to ensure that the pallet 17 is in a horizontal state during the process of the pull rope 18 and the connecting rope 20 pulling the pallet 17 to move, thereby ensuring the stability of the support of the pallet 17. It should be further explained that the slider 45 can ensure the stability of the vertical sliding of the slider 45 by installing a vertical slide rail on one side of the chassis 3.

[0031] In order to facilitate the automatic movement of the support plate 17, as an embodiment of the present invention, a horizontally arranged driving rod 23 is rotatably connected to the chassis 3, a guide block 24 is fixedly connected to the driving rod 23, an internal threaded tube 25 corresponding to the driving rod 23 is connected to the back plate 7, a spiral guide groove corresponding to the guide block 24 is provided in the internal threaded tube 25, a driving pulley 26 is connected to the driving rod 23, a driven pulley 27 corresponding to the driving pulley 26 is provided at one end of the winding shaft 19, a one-way bearing 28 is connected between the driven pulley 27 and the winding shaft 19, a transmission belt is used for transmission between the driving pulley 26 and the driven pulley 27, a torsion spring 44 is connected between the winding shaft 19 and the driven pulley 27, and a limiting structure for locking the support plate 17 is connected in the storage frame 16.

[0032] When in use, when the user inserts the powder collecting box assembly between the two sets of side plates 8, the internal threaded tube 25 will be sleeved on the driving rod 23, and the limiting structure will be stuck above the stacked support plates 17. The internal threaded tube 25 and the guide block 24 cooperate to rotate the driving rod 23, and the driving rod 23 drives the driven pulley 27 to rotate through the pulley transmission, so that the torsion spring 44 accumulates force. After the powder collecting box assembly is completely inserted between the two sets of side plates 8, the back plate 7 is connected to the side plate 8 through the lock buckle; After the briquetting mechanism pushes multiple groups of briquetting powders to the topmost support plate 17, the block powder will squeeze the limiting structure to unlock it. At this time, the torsion spring 44 drives the winding shaft 19 to rotate, pulling the topmost support plate 17 upward. After the support plate 17 supporting the block powder moves upward, the limiting structure resets and clamps the next group of support plates 17, and repeats this process to ensure that all support plates 17 support the briquetting powder.

[0033] In order to use the limiting structure, as an embodiment of the present invention, the limiting structure includes an extrusion plate 29, which is located above the inner side of the opening 21, and the upper surface of the extrusion plate 29 is in sliding contact with the inner wall of the opening 21. The extrusion plate 29 is fixedly connected to the storage frame 16 through a spring. The pressing mechanism pushes the powder blocks into the storage frame 16 and squeezes the extrusion plate 29 to move, thereby unlocking the support plate 17 under the extrusion plate 29.

[0034] When in use, after the briquetting mechanism pushes multiple groups of briquetting powders onto the top support plate 17, it will rely on the block powder to squeeze the squeeze plate 29, so that the squeeze plate 29 is separated from the upper surface of the support plate 17, thereby unlocking the top support plate 17. At this time, the torsion spring 44 drives the reel 19 to rotate, pulling the top support plate 17 to move up. After the support plate 17 supporting the block powder moves up, the spring drives the squeeze plate 29 to reset and clamp the next group of support plates 17, and so on and so forth, ensuring that all support plates 17 support the briquetting powders. It should be pointed out that in order to facilitate the block powder to push the squeeze plate 29 to move, a ball bearing can be installed on the lower surface of the squeeze plate 29 to reduce the friction between the squeeze plate 29 and the edge of the support plate 17.

[0035] In order to ensure the use of the vibration powder sprinkling part, as an embodiment of the present invention, the vibration powder sprinkling part includes a vibration powder sprinkling position bracket 30 arranged on the product conveying part, the vibration powder sprinkling position bracket 30 is fixedly connected to the chassis 3, and a vibration powder sprinkling device 31 is installed on the vibration powder sprinkling position bracket 30, and a powder hopper 32 is connected to the vibration powder sprinkling device 31, and an amplitude adjustment knob 33 for adjusting the amplitude of the vibration powder sprinkling device 31 is provided on the chassis 3.

[0036] When in use, the vibrating powder sprinkling part vibrates and sprinkles the desired powder on the product surface onto the product. Specifically, the vibrating powder sprinkling device 31 vibrates and sprinkles the powder in the powder hopper 32 onto the product surface, and the amplitude adjustment knob 33 is used to adjust the amount of powder sprinkling by vibration.

[0037] In order to ensure the use of the powder atomization part, one side of the vibrating powder spreading bracket 30 is connected to an atomization and back-suction bracket 34, and the powder atomization part includes an atomization nozzle 35 capable of adjusting the atomization distance, and the atomization nozzle 35 is installed on the atomization and back-suction bracket 34, and the chassis 3 is provided with an atomization gas volume adjustment knob 36 for adjusting the atomization gas volume of the atomization nozzle 35, and the atomization and back-suction bracket 34 is provided with a back-suction powder pipe 42.

[0038] When in use, the powder atomization part is used to atomize the powder on the product surface and the conveyor belt to make the powder on the product surface uniform. Specifically, the atomization gas volume adjustment knob 36 adjusts the atomization gas volume, and the distance between the atomization nozzle 35 and the product is adjusted to atomize the powder, so that the powder is more uniform on the product surface.

[0039] In order to ensure the effect of the powder recovery part, as an embodiment of the present invention, the powder return suction part includes a powder removal filter 37 arranged in the chassis 3, and the powder removal filter 37 is connected to the powder return suction pipe 42 through a pipe. An explosion-proof motor 38 is provided in the chassis 3, and the output end of the explosion-proof motor 38 is connected to the wind wheel 39, and the wind wheel 39 is connected to the powder removal filter 37. The chassis 3 is provided with a dust removal device, and a powder removal collection box 40 is provided under the powder removal filter 37. A powder removal solenoid valve 41 for cleaning the powder removal filter 37 is installed in the chassis 3.

[0040] When in use, the powder re-absorption part is used to re-absorb excess powder on the product surface and in the powder atomization part, so that the powder on the product surface is uniform and the safety hazard caused by dust diffusion is eliminated; specifically, the explosion-proof motor 38 and the wind wheel 39 rotate to draw away the air at the powder removal filter 37 to form a negative pressure, and the powder removal filter 37 is connected to the powder re-absorption pipe 42 to absorb the dust in the air near the powder atomization position and the excess powder on the product surface, so that the powder on the product surface is more uniform. Absorbing the dust in the air can prevent the risk of dust explosion. In order to prevent the powder removal filter 37 from being blocked by powder, compressed air is blown into the powder removal filter 37 through the powder removal solenoid valve 41 at regular intervals to remove the powder attached to the powder removal filter 37 and to the powder removal collection box 40 for recycling.
