[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-8 The shown is a powder coating device that avoids waste, including a powder coating box 1, a stirring mechanism 3, a recycling mechanism 4, and a powder dispensing mechanism 8;

[0029] The top of the powder coating box 1 has an opening near the left side and a box cover 2 with a handle. The top of the powder coating box 1 has a feed hopper 5 near the right side and a discharge port near the bottom on the right side wall. The powder spreading mechanism 8 is located inside the powder coating box 1 below the box cover 2, and the powder spreading mechanism 8 is located below the powder spreading mechanism 8.

[0030] The coating mechanism includes a first coating mesh plate 15 and a second coating mesh plate 14. The first coating mesh plate 15 is located above the second coating mesh plate 14 and both the first coating mesh plate 15 and the second coating mesh plate 14 are placed at relative inclinations. A sloping plate 7 is provided on the right side of the second coating mesh plate 14, and the right side of the sloping plate 7 passes through the discharge port and extends to the outside of the coating box 1. The first coating mesh plate 15 and the second coating mesh plate 14 are bent at equal intervals, and a sloping buffer area 12 is formed at the bend. A fixed rod 11 is connected through and rotatably between the two ends of the first coating mesh plate 15 on the left side and the second coating mesh plate 14 on the right side. The ends of the two fixed rods 11 are fixedly connected to the inner side wall of the adjacent coating box 1. Multiple protrusions 10 are fixedly connected at equal intervals on the top of the first coating mesh plate 15 and the second coating mesh plate 14.

[0031] The actuating mechanism 3 is located on the front side of the coating box 1, and the recycling mechanism 4 is located on the rear side of the coating box 1.

[0032] Before using the device, connect it to a power source. The device has an external controller. When food needs to be coated with flour, first pull the handle on the lid 2 to open it, then pour the flour coating material into the flour storage frame 84. Close the lid 2, and then start the drive motor 35 via the controller. The drive motor 35 drives the left rotating rod 36 to rotate. Under the action of the first chain 33 and the second chain 32, the three rotating rods 36 rotate, thereby driving the eccentric wheel 38 to rotate, pushing the flour storage frame 84, the first flour coating plate 15, and the second flour coating plate 14 upwards. The fixing rod 11 limits one end of the first flour coating plate 15 and the second flour coating plate 14 to prevent them from shifting during the pushing process. At this time, the flour coating material falls from the flour storage frame 84 onto the first flour coating plate 15 and the second flour coating plate 14. Then pour the food into the feed hopper 5. The food falls onto the first flour coating plate 15 and... The food rolls along the first coating mesh 15 and falls onto the second coating mesh 14. From the second coating mesh 14, it rolls onto the inclined plate 7 and then into the collection frame 6 for collection. Due to the vibration of the first coating mesh 15 and the obstruction of the protrusion 10, the food will turn back and forth. The inclined buffer 12 has a small inclination angle and will accumulate more coating material. When the food rolls to the inclined buffer 12, it will slow down and be coated with a sufficient amount of coating material, so that the powder is evenly attached to the food. Some of the coating material on the first coating mesh 15 will fall onto the second coating mesh 14 for alignment and replenishment. The coating material falling off the second coating mesh 14 will fall into the collection funnel 13 for collection and enter the bottom of the conveying cylinder 41 through the collection pipe 16. Then, the controller starts the lifting motor 42 to transport the coating material in the conveying cylinder 41 from the conveying pipe 9 to the powder storage mesh frame 84 to achieve the reuse of the powder.

[0033] The powder-spreading mechanism 8 includes a powder storage mesh frame 84 and two connecting components. The two connecting components are symmetrically arranged at both ends of the powder storage mesh frame 84. Each connecting component includes two fixing plates 81, two return springs 85, two support rods 82, and an L-shaped connecting plate 83. The two fixing plates 81 are symmetrically arranged, with the side wall of the uppermost fixing plate 81 fixedly connected to the inner wall of the powder-coating box 1. The two support rods 82 are symmetrically arranged between the two fixing plates 81, with the ends of the two support rods 82 respectively fixedly connected to the corresponding fixing plates 81. The L-shaped connecting plate 83... The connecting wall is fixedly connected to the middle position of one end of the powder storage mesh frame 84 near the top. The sliding wall of the L-shaped connecting plate 83 is set between the two fixed plates 81, and the sliding wall of the L-shaped connecting plate 83 and the two support rods 82 are each provided with a sliding hole. The two sliding holes are respectively slidably sleeved on the outer wall of the corresponding support rods 82. The two return springs 85 are respectively sleeved on the support rods 82 between the L-shaped connecting plate 83 and the uppermost fixed plate 81. The two ends of the two return springs 85 are respectively fixedly connected to the corresponding L-shaped connecting plate 83 and fixed plate 81.

[0034] The uppermost fixing plate 81 fixes the powder storage mesh frame 84, and the lowermost fixing plate 81 limits the L-shaped connecting plate 83. When the eccentric wheel 38 contacts the powder storage mesh frame 84, the powder storage mesh frame 84 drives the L-shaped connecting plate 83 to move upward along the support rod 82. At this time, the return spring 85 is compressed and contracts. When the eccentric wheel 38 is no longer in contact with the powder storage mesh frame 84, the return spring 85 resets and drives the L-shaped connecting plate 83 to rebound, causing the powder storage mesh frame 84 to move downward, thereby vibrating the powder storage mesh frame 84, preventing the powder coating material inside the powder storage mesh frame 84 from accumulating, and facilitating the falling of the powder coating material inside the powder storage mesh frame 84.

[0035] The actuating mechanism 3 includes a support plate 31, a drive motor 35, three rotating rods 36, three first sprockets 34, second sprockets 37, a first chain 33, a second chain 32, and multiple eccentric wheels 38. The support plate 31 is fixedly connected to the front side of the coating box 1 near the lower left corner. The drive motor 35 is fixedly connected to the top of the support plate 31. The three rotating rods 36 are arranged in a triangular shape. The three rotating rods 36 are respectively located at the bottom of the second coating mesh plate 14 near the left side, the bottom of the first coating mesh plate 15 near the right side, and the bottom of the powder storage mesh frame 84 in the middle position. One end of each of the three rotating rods 36 penetrates the front and rear side walls of the coating box 1. Bearings are fixedly fitted near both ends of each of the three rotating rods 36, and the outer rings of the bearings are respectively embedded in the corresponding side walls of the coating box 1. Four eccentric wheels 38 are fixedly fitted on the rods 36 near the middle position. The three rotating rods 36 are all fixedly connected to the first sprockets 34 at the front end of the coating box 1. The rightmost rotating rod 36 is fixedly fitted with a second sprocket 37 near the front end. The first chain 33 is fitted between the two first sprockets 34 at the top and rightmost positions and meshes with the two first sprockets 34 at the top and rightmost positions. The second sprocket 37 is fitted between the leftmost first sprocket 34 and the second sprocket 37 and meshes with the leftmost first sprocket 34 and the second sprocket 37. The output end of the drive motor 35 is fixedly connected to the leftmost rotating rod 36. The two outermost eccentric wheels 38 and the two innermost eccentric wheels 38 on each rotating rod 36 are set perpendicularly.

[0036] The support plate 31 supports the drive motor 35. The drive motor 35 is started by the controller, causing the left rotating rod 36 to rotate. This causes the first sprocket 34 on the left rotating rod 36 to rotate. Under the action of the second chain 32, the first sprocket 34 on the left rotates, causing the second sprocket 37 to rotate, which in turn causes the right rotating rod 36 to rotate. The right rotating rod 36 then causes the first sprocket 34 on the right to rotate. Under the action of the first chain 33, the first sprocket 34 on the right rotates, causing the topmost sprocket 34 to rotate, thus rotating the topmost sprocket. Rotating the lever 36 causes the eccentric wheels 38 on the three rotating levers 36 to rotate. The eccentric wheels 38 move the coating box 1 to facilitate the falling of the coating material. The eccentric wheels 38 also move the first coating screen 15 and the second coating screen 14 to facilitate the food to roll and be coated with coating material on the first coating screen 15 and the second coating screen 14. The eccentric wheels 38 are arranged vertically and alternately to make the frequency of the eccentric wheels 38 higher and the amplitude of the movement less too large. This avoids the problem of uneven coating caused by the food jumping on the first coating screen 15 and the second coating screen 14 due to the excessive amplitude of the movement.

[0037] The bottom of the inner cavity of the coating box 1 is provided with a material collection funnel 13, which is located below the second coating mesh plate 14. The bottom wall of the coating box 1 is provided with a discharge port that matches the material collection funnel 13. The feed hopper 5 is connected to the inside of the coating box 1 and the bottom of the feed hopper 5 extends to the top of the first coating mesh plate 15. The recycling mechanism 4 includes a conveying cylinder 41, a lifting motor 42, a connecting rod 43, a spiral lifting blade 44, a collection pipe 16, and a conveying pipe 9. The lifting motor 42 is fixedly connected to the top of the conveying cylinder 41. One end of the connecting rod 43 is fixedly connected to the output end of the lifting motor 42, and the other end passes through the conveying cylinder 41 and is inserted into the conveying cylinder 41. The rotating lifting blade 44 is fixedly sleeved on the outer wall of the part of the connecting rod 43 located inside the conveying cylinder 41. The conveying cylinder 41 has a through hole near both ends on the side wall facing the powder coating box 1. One end of the collecting pipe 16 is connected to the discharge port and is fixedly connected to the discharge port. The other end of the collecting pipe 16 is connected to the lowermost through hole of the conveying cylinder 41 and is fixedly connected to the through hole. One end of the conveying pipe 9 is connected to the uppermost through hole of the conveying cylinder 41 and is fixedly connected to the through hole. The other end of the conveying pipe 9 passes through the side wall of the powder coating box 1 and extends to the top of the powder storage mesh frame 84. The conveying pipe 9 is fixedly connected to the side wall of the powder coating box 1.

[0038] After the food is poured into the feeding hopper 5, it falls onto the first coating mesh plate 15. Excess coating material on the second coating mesh plate 14 will fall into the collecting funnel 13 for collection and then fall into the bottom of the conveying cylinder 41 through the collecting pipe 16. Then, the controller starts the lifting motor 42, which drives the connecting rod 43 to rotate, causing the spiral lifting blade 44 (the spiral lifting blade 44 matches the inner diameter of the conveying cylinder 41) to rotate. The spiral lifting blade 44 lifts the coating material at the bottom of the conveying cylinder 41 and transports it from the conveying pipe 9 to the powder storage mesh frame 84 to achieve powder reuse and avoid powder waste.

[0039] The first coating mesh 15 is higher on the right and lower on the left, and the second coating mesh 14 is higher on the left and lower on the right. The right side of the second coating mesh 14 is fixedly connected to an inclined plate 7. The coating box 1 is provided with a collection frame 6 on the right side. The width of the discharge port matches the inclined plate 7. One end of the inclined plate 7 extends above the collection frame 6.

[0040] The widths of the first coating mesh 15 and the second coating mesh 14 match the width of the coating box 1. The first coating mesh 15 and the second coating mesh 14 are inclined to facilitate the food to roll and coat with flour on the first coating mesh 15 and the second coating mesh 14. The food first falls onto the first coating mesh 15, rolls and coats with flour, and then falls onto the second coating mesh 14 to continue coating with flour, so that the surface of the food can be fully coated with flour, ensuring the qualified rate of food coating. Finally, the food falls from the inclined plate 7 into the collection box 6 to wait for collection. The bottom of the coating box 1 is provided with four support columns to support the coating box 1.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
