Abstract
Description
Technical Field
[0001] This utility model relates to a coating machine, and more particularly to a coating machine for producing Dragon Ball popping beads. Background Technology
[0002] Dragon ball popping boba, also known as popping boba, is a common additive in beverages such as milk tea. During production, carrageenan, konjac gum, gellan gum, xanthan gum, salt and alkali additives, glucose powder, etc., are mixed with red beans, water chestnuts, etc., and then granulated. After granulation, the granules need to be coated with powder. Currently, the coating process is done using a coating machine. However, existing coating machines mainly use a swinging structure, placing the powder and granules to be coated in a cavity, and then swinging the cavity to mix and coat the powder and granules. This often results in granules piling up, leading to uneven coating in some areas. Utility Model Content
[0003] The purpose of this invention is to provide a coating machine for the production of Dragon Ball popping beads. This invention effectively improves the uniformity of coating.
[0004] The technical solution of this utility model: A powder coating machine for producing Dragon Ball popping beads, including a base, an eccentric vibration motor inside the base, a powder coating trough with an annular flat groove structure above the base, a sealing cover plate above the powder coating trough, a partition plate inside the powder coating trough, an inclined guide surface on one side of the partition plate located on the bottom surface of the powder coating trough, a discharge port located at the bottom of the powder coating trough outside the inclined guide surface, and a gate plate at the discharge port; a feed port on the other side of the partition plate; a first-end powder blowing pipe on the other side wall of the partition plate, a side powder outlet on the side of the first-end powder blowing pipe, and a set of annularly distributed intermediate powder blowing pipes inside the powder coating trough, with a lower powder outlet below the intermediate powder blowing pipes.
[0005] In the aforementioned powder coating machine for producing Dragon Ball popping beads, an inclined discharge screen plate is provided at the outer end of the discharge port, a powder recovery box is provided below the inclined discharge screen plate, and a conveyor belt is provided at the discharge port of the inclined discharge screen plate.
[0006] The aforementioned powder coating machine for producing Dragon Ball popping beads also includes a powder storage silo, a discharge pipe below the powder storage silo, a conical mixing chamber below the discharge pipe, an air blowing pipe inside the conical mixing chamber, a blower connected to the outer end of the air blowing pipe located outside the conical mixing chamber, an air outlet at the inner end of the air blowing pipe located on the left side of the discharge pipe, and a connecting hose connected to the first powder blowing pipe and the middle powder blowing pipe at the other end of the conical mixing chamber.
[0007] Compared with existing technologies, this invention features an eccentric vibration motor within the base, a powder-coating trough with an annular flat groove structure above the base, an inclined guide surface and discharge port on one side of the partition, and a feed port above the other side of the partition. These components work together to allow the items to be coated in the powder-coating trough to move annularly from the feed port to the discharge port. By incorporating a leading powder-blowing pipe and a set of annularly distributed intermediate powder-blowing pipes on the side wall of the partition, powder coating can be applied to the items from multiple locations, ensuring uniform coating. Simultaneously, the vibration and movement of the items effectively reduces their accumulation, and the changing position of the items further contributes to the uniformity of powder coating.

Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0012] Example. A coating machine for producing Dragon Ball popping boba, configured as follows: Figure 1-2 As shown, the device includes a base 1, an eccentric vibration motor 2 inside the base 1, a powder coating trough 3 with an annular flat groove structure above the base 1, a sealing cover plate 4 above the powder coating trough 3, a partition plate 5 inside the powder coating trough 3, an inclined guide surface 6 on one side of the partition plate 5 located on the bottom surface of the powder coating trough 3, a discharge port 7 located at the bottom of the powder coating trough 3 outside the inclined guide surface 6, and a gate plate 8 at the discharge port 7; a feed inlet 9 on the other side of the partition plate 5 on the sealing cover plate 4; a first-end powder blowing pipe 10 on the other side wall of the partition plate 5, a side powder outlet on the side of the first-end powder blowing pipe 10, and a set of annularly distributed intermediate powder blowing pipes 11 inside the powder coating trough 3, with a lower powder outlet below the intermediate powder blowing pipes 11.
[0013] An inclined discharge screen plate 12 is provided at the outer end of the discharge port 7, a powder recovery box 13 is provided below the inclined discharge screen plate 12, and a conveyor belt 14 is provided at the discharge port of the inclined discharge screen plate 12.
[0014] It also includes a powder storage bin 15, a discharge pipe 16 below the powder storage bin 15, a conical mixing chamber 17 below the discharge pipe 16, an air blowing pipe 18 inside the conical mixing chamber 17, a blower 19 located outside the conical mixing chamber 17 connected to the outer end of the air blowing pipe 18, and an air outlet at the inner end of the air blowing pipe 18 located on the left side of the discharge pipe 16. The other end of the conical mixing chamber 17 is provided with a connecting hose connected to the first powder blowing pipe 10 and the middle powder blowing pipe 11.
[0015] The discharge port 7 is provided with sealing guide grooves on both sides that cooperate with the gate, and an electric cylinder is provided above the gate.
[0016] There are multiple powder blowing pipes at the beginning, which are distributed vertically on the side of the partition.
[0017] A set of ring-shaped ultraviolet disinfection lamps is installed on the inner top surface of the sealed cover.
[0018] The bottom of the sealing guide groove is an open structure.
[0019] The working process of this utility model is as follows: In the initial state, the gate is closed. The first powder blowing pipe and the middle powder blowing pipe spray powder first, so that a layer of powder is laid on the bottom surface of the powder coating tank. Then, the particles to be coated begin to enter the powder coating tank from the feed inlet. The particles are first wrapped by the powder blown out by the first powder blowing pipe, and then fall to the bottom of the powder coating tank. Under the vibration of the eccentric vibration motor, the particles to be coated move in a ring along the powder coating tank (moving from the feed inlet to the discharge outlet). During the movement, the particles to be coated will pass through multiple middle powder blowing pipes in sequence. The middle powder blowing pipes apply powder and coat the particles from the lower powder outlet and the inclined powder outlet to ensure the uniformity of powder coating. After being coated with powder, the particles move to the inclined guide surface. The gate is opened at regular intervals by the action of the electric cylinder. The powder-coated particles fall to the inclined discharge screen plate under the action of gravity for sieving. Excess powder falls to the powder recycling box, while the powder-coated particles fall to the conveyor belt and are transported to the next process.
[0020] When the gate is opened, the middle powder blowing pipe and the first powder blowing pipe stop discharging powder, the eccentric vibration motor also stops vibrating, the feed inlet stops feeding, and then the gate is opened. After the powder-coated particles on the inclined guide surface have finished discharging, the gate is closed, and the above components start working again.
[0021] An electric valve is installed on the discharge pipe to control the discharge of powder.
[0022] Air blowing and powder discharge process: The blower blows air into the conical mixing chamber. Since the air outlet of the blowing pipe is located on the right side of the discharge pipe, a negative pressure is formed at the outlet of the discharge pipe, which draws the powder into the conical mixing chamber and blows it into each connecting hose. Then, the powder enters the first powder blowing pipe and the middle powder blowing pipe respectively for powder discharge.
[0023] By placing the air outlet of the blowing pipe on the right side of the discharge pipe, a negative pressure is created at the outlet of the discharge pipe, which is conducive to sucking out the powder and facilitating discharge, thus preventing the discharge pipe from becoming blocked.
