Therefore, the powder coating and feeding device of this utility model not only improves the production efficiency of powder coating and packaging, but also reduces operating costs.

[0035] The following description, in conjunction with the accompanying drawings, provides a more detailed explanation of the powder coating and feeding device of this utility model.

[0036] This embodiment provides a breading feeding device, which mainly includes a feeding pipe 10 and a discharging pipe 20. The feeding pipe 10 is configured to connect to a hopper in the breading supply system. The hopper is used to store breading and to deliver breading to the feeding pipe 10 when needed. The design of the feeding pipe 10 ensures that the breading can be smoothly delivered from the hopper to the discharging pipe 20. The discharging pipe 20 is installed on and connected to the feeding pipe 10. The discharging pipe 20 consists of a fixed pipe assembly 21, a connecting cylinder 23, and a movable pipe assembly 22. One end of the fixed pipe assembly 21 is fixedly installed on the feeding pipe 10, and it includes a first rotating buckle 211 and a first connecting pipe 212. The first rotating buckle 211 is sleeved on the outer periphery of the first connecting pipe 212 for detachable connection with the movable pipe assembly 22. One end of the first connecting pipe 212 is connected to the feeding pipe 10, ensuring that the breading can smoothly enter the fixed pipe assembly 21. One end of the movable pipe assembly 22 is detachably mounted on and connected to the other end of the fixed pipe assembly 21. The movable pipe assembly 22 includes a second rotary snap fastener 221 and a second connecting pipe 222. The second rotary snap fastener 221 is sleeved on the outer periphery of the second connecting pipe 222 and is used to rotate and snap into the first rotary snap fastener 211. One end of the second connecting pipe 222 is connected to the connecting cylinder 23, and the other end is connected to the first rotary snap fastener 211 through the second rotary snap fastener 221. This design allows the movable pipe assembly 22 to be easily assembled and disassembled with the fixed pipe assembly 21, improving operational flexibility. The connecting cylinder 23 serves as the connecting component between the fixed pipe assembly 21 and the movable pipe assembly 22. One end of the connecting cylinder 23 is connected to the second connecting pipe 222 of the movable pipe assembly 22, and the other end is connected to the packaging machine. In this way, the powder coating can be smoothly conveyed from the feeding pipe 10 to the packaging machine for packaging through the feeding pipe 20.

[0037] In actual use, the operator only needs to rotate the second rotating clip 221 of the movable pipe assembly 22 onto the first rotating clip 211 of the fixed pipe assembly 21 to complete the assembly of the discharge pipe 20. When disassembly is required, simply rotate the second rotating clip 221 in the opposite direction. This operation method is simple and quick, greatly improving operational efficiency.

[0038] The breading and feeding device according to the embodiment of this utility model has at least the following beneficial effects: The second rotating buckle 221 of the movable pipe assembly 22 allows the second connecting pipe 222 of the breading packaging machine to be quickly connected to the first connecting pipe 212 of the feeding pipe 10, thereby quickly connecting it to the breading supply system. The rapid engagement of the first rotating buckle 211 and the second rotating buckle 221 facilitates manual and rapid connection of the hopper of the fried chicken breading packaging machine to the supply system, simplifying the manual connection process and improving operational efficiency, thereby increasing production efficiency.

[0039] Furthermore, referring to Figures 2 to 3 In some embodiments of this utility model, the first rotary buckle 211 includes a first locking hook 2111, a first engaging portion 2112, a first clearance portion 2113, and a first rotary cavity 2114; the second rotary buckle 221 includes a second locking hook 2211, a second engaging portion 2212, a second clearance portion 2213, and a second rotary cavity 2214. The first rotary buckle 211 and the second rotary buckle 221 are arranged opposite to each other. The first locking hook 2111 can be engaged with the second engaging portion 2212, and the second locking hook 2211 can be engaged with the first engaging portion 2112. The first clearance part 2113 is used to avoid the second locking hook 2211, and the second clearance part 2213 is used to avoid the first locking hook 2111. The second locking hook 2211 can rotate in the first rotating cavity 2114 so that the second locking hook 2211 is engaged with the first engaging part 2112. The first locking hook 2111 can rotate in the second rotating cavity 2214 so that the first locking hook 2111 is engaged with the second engaging part 2212. The first rotating buckle 211 and the second rotating buckle 221 are arranged opposite to each other and connected so that the first connecting pipe 212 and the second connecting pipe 222 are connected.

[0040] Specifically, the first rotary latch 211 includes a first hook 2111, a first engaging portion 2112, a first clearance portion 2113, and a first rotating cavity 2114. The first hook 2111 engages with the second engaging portion 2212 of the second rotary latch 221 to ensure a stable connection. The first engaging portion 2112 receives the second hook 2211 of the second rotary latch 221, forming a mutually engaging structure. The first clearance portion 2113 is designed to provide clearance space when the second hook 2211 is inserted into the first rotating cavity 2114, preventing interference. The first rotating cavity 2114 allows the second hook 2211 to rotate within it, facilitating a smooth engagement.

[0041] Accordingly, the second rotary latch 221 includes a second hook 2211, a second engaging portion 2212, a second clearance portion 2213, and a second rotary cavity 2214. The second hook 2211 engages with the first engaging portion 2112 of the first rotary latch 211, and the second engaging portion 2212 receives the first hook 2111 of the first rotary latch 211. The second clearance portion 2213 provides clearance space for the first hook 2111 to be inserted into the second rotary cavity 2214, ensuring a smooth connection process. The second rotary cavity 2214 allows the first hook 2111 to rotate within it, achieving engagement with the second engaging portion 2212.

[0042] During actual assembly, the operator positions the first rotating latch 211 opposite the second rotating latch 221. By rotating the second rotating latch 221, the second locking hook 2211 enters the first rotating cavity 2114 and rotates to a position where it engages with the first locking part 2112. Simultaneously, the first locking hook 2111 also rotates within the second rotating cavity 2214, engaging with the second locking part 2212. In this way, the first rotating latch 211 and the second rotating latch 221 are tightly connected, ensuring communication between the first connecting pipe 212 and the second connecting pipe 222. This connection method is both secure and easy to disassemble.

[0043] When disassembly is required, the operator simply needs to rotate the second rotary buckle 221 and the first rotary buckle 211 in the opposite direction, causing the first locking hook 2111 and the second locking hook 2211 to disengage from the second locking part 2212 and the first locking part 2112 respectively, thus completing the disassembly process. This rotary buckle design not only improves the ease of operation but also ensures the reliability and sealing of the connection, effectively preventing leakage of the powder coating during the conveying process.

[0044] Furthermore, referring to Figures 2 to 3 In some embodiments of this utility model, one end of the connecting cylinder 23 is sleeved on one end of the second connecting pipe 222, and the connecting cylinder 23 is fastened to the second connecting pipe 222 by a fastening assembly 30. The fastening assembly 30 includes a traction rope 31, a top plate 32, and a rotating screw 33. The traction rope 31 can be wound around the outside of the connecting cylinder 23 and is flexible; the inner side of the top plate 32 abuts against the outer side of the connecting cylinder 23, and a sleeve 35 is provided on the outer side of the top plate 32; the rotating screw 33 is rotatably disposed in the sleeve 35, and a nut 34 is sleeved on the threaded portion of the rotating screw 33, and the two ends of the traction rope 31 are respectively connected to the opposite sides of the nut 34.

[0045] In the powder coating and feeding device of this utility model, the connection between the connecting cylinder 23 and the second connecting pipe 222 is achieved by using a fastening assembly 30 to ensure the stability and reliability of the connection. Specifically, one end of the connecting cylinder 23 is sleeved on one end of the second connecting pipe 222. To achieve this connection, a special fastening assembly 30 is designed. The fastening assembly 30 includes a traction rope 31, a top plate 32, and a rotating screw 33. The traction rope 31 is flexible and can be wound around the outside of the connecting cylinder 23 to provide the necessary tension for fastening. The inner side of the top plate 32 abuts against the outer side of the connecting cylinder 23, which plays a role in transmitting tension and ensuring close contact between the connecting cylinder 23 and the second connecting pipe 222. A sleeve 35 is provided on the outer side of the top plate 32 for installing and supporting the rotating screw 33. The rotating screw 33 is rotatably disposed in the sleeve 35, and a nut 34 is sleeved on its threaded portion. When the rotating screw 33 rotates, the nut 34 moves along the threaded portion, thereby pulling or loosening the traction rope 31. The two ends of the traction rope 31 are respectively connected to the opposite sides of the nut 34. In this way, when the nut 34 moves, the traction rope 31 will tighten or loosen. While the traction rope 31 tightens the connecting cylinder 23, it can also drive the top plate 32 to apply or release pressure on the connecting cylinder 23.

[0046] In actual operation, the operator only needs to rotate the screw 33 to adjust the pressure of the top plate 32 on the connecting cylinder 23 through the action of the nut 34 and the traction rope 31, thereby achieving the fastening or disassembly of the connecting cylinder 23 and the second connecting pipe 222. This fastening component 30 is not only easy to operate, but also ensures a stable connection between the connecting cylinder 23 and the second connecting pipe 222, effectively preventing leakage and loosening of the powder coating during the conveying process.

[0047] In some embodiments of this invention, a friction texture (not shown in the figure) is provided on the outer peripheral surface of one end of the connecting cylinder 23 of the second connecting pipe 222. The friction texture has a specific texture and roughness, which can significantly increase the friction between the outer peripheral surface of the second connecting pipe 222 and the inner wall of the connecting cylinder 23. When the connecting cylinder 23 is sleeved on the second connecting pipe 222, the presence of the friction texture makes it more difficult for the connecting cylinder 23 to slide or rotate relative to the second connecting pipe 222, thereby ensuring a tight connection between the two.

[0048] In some embodiments of this invention, the connecting cylinder 23 is flexible and made of a transparent material. Specifically, the connecting cylinder 23 is a transparent plastic film. The flexible material used in the connecting cylinder 23 allows it to better adapt to different connection angles and positions during installation and use, reducing connection difficulties or damage that may result from excessive rigidity. Simultaneously, the transparent material of the connecting cylinder 23 allows operators to visually observe the powder flow inside, enabling timely detection and handling of potential blockages or abnormal flow. The choice of a transparent material not only improves the operability of the device but also helps ensure the smooth operation of the production process.

[0049] In the powder coating and feeding device of this utility model, the connecting cylinder 23 is made of transparent plastic film material. Specifically, the flexibility of the transparent plastic film allows the connecting cylinder 23 to be easily bent and adjusted in shape during installation to adapt to different connection requirements and spatial layouts.

[0050] Reference Figure 1 In some embodiments of this utility model, multiple discharge pipes 20 are provided on the lower side of the feeding pipe 10, and the multiple discharge pipes 20 are arranged at intervals along the extension direction of the feeding pipe 10. Specifically, each discharge pipe 20 is connected to the feeding pipe 10, and through precise design and installation, the smooth flow of the coating powder is ensured. The number and spacing of the discharge pipes 20 can be flexibly adjusted according to actual production needs and equipment layout to achieve the best discharge effect. In practical applications, when the coating powder is conveyed through the feeding pipe 10, it will be diverted to each discharge pipe 20 as needed, and then evenly distributed from the outlet of the discharge pipe 20. This multi-point discharge design not only improves production efficiency, but also ensures the uniform distribution of the coating powder during packaging or processing, improving product quality and consistency.

[0051] Reference Figure 1 In some embodiments of this utility model, a screw conveyor mechanism 11 is provided in the feeding pipe 10, and the screw conveyor mechanism 11 is configured for conveying powder coating. To efficiently and stably convey the powder coating, a screw conveyor mechanism 11 is provided in the feeding pipe 10. The screw conveyor mechanism 11 is a commonly used powder conveying device, which propels the powder coating forward in the feeding pipe 10 through the rotational motion of the screw. Specifically, the screw conveyor mechanism 11 includes one or more screws that extend axially along the feeding pipe 10 and are tightly fitted with the inner wall of the feeding pipe 10. When the screw rotates under the drive of the drive device, its helical blades push the powder coating along the feeding pipe 10. Due to the rotational motion of the screw, the powder coating is subjected to continuous thrust, thereby ensuring its stable conveying in the feeding pipe 10.

[0052] Reference Figures 2 to 3 In some embodiments of this utility model, the fixed pipe assembly 21 is equipped with a control valve 2121, which is located on the first connecting pipe 212. To achieve precise control of the powder coating flow rate, a control valve 2121 is installed on the first connecting pipe 212 of the fixed pipe assembly 21. The control valve 2121 is a device capable of regulating or cutting off fluid flow; by changing its opening degree, the flow rate of the powder coating through the first connecting pipe 212 can be precisely controlled. Specifically, the control valve 2121 can be a manual valve, a solenoid valve, or a pneumatic valve, selected according to actual production needs and the degree of automation. Manual valves are suitable for situations requiring manual adjustment of the powder coating flow rate, offering simple and intuitive operation; solenoid valves and pneumatic valves are suitable for situations requiring remote or automated control, enabling automatic adjustment of the powder coating flow rate.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
