[0057] The present application provides a powder coating device and a method for applying the powder coating device. The powder coating device and the method for applying the powder coating device of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0058] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a powder coating device 100, which can be applied to the field of food processing or other fields where powder coating operations need to be completed, to realize the powder coating operation of the objects to be coated, and can also realize the operations of sieving powder, returning powder, and discharging slag, so as to realize a multifunctional integrated powder coating device 100. The powder coating device 100 includes a rotatable drum, and the drum includes a shell, a powder coating chamber arranged in the shell, a powder storage chamber, and a powder transfer part arranged between the powder coating chamber and the powder storage chamber. Among them, the powder coating chamber is used to accommodate powder and objects to be coated with powder. The powder storage chamber is used to accommodate powder, such as recovering and accommodating powder after sieving powder from the powder coating chamber. The powder is transferred between the powder coating chamber and the powder storage chamber through the powder transfer part. It should be noted that when the powder coating device 100 is applied to the field of food processing, the objects to be coated with powder can refer to foods to be coated with powder, such as chicken legs, chicken nuggets and other food materials, and the powder coating device 100 can realize the powder coating operation of the food materials. When the powder coating device 100 is applied to other fields that require powder coating, the object to be coated may also refer to a handicraft that requires powder coating, etc., and the present application does not limit this. Optionally, the powder coating device 100 may further include a base 120, and the drum 110 is rotatably connected to the base 120. The base 120 provides support for the drum 110, and the drum 110 provides space for implementing powder coating, powder screening, slag discharge, and powder return.

[0059] The powder coating device of the embodiment of the present application integrates the powder coating chamber and the powder storage chamber into the same drum, and the powder in the powder coating chamber can be transferred between the powder coating chamber and the powder storage chamber through the powder transfer part between the powder coating chamber and the powder storage chamber. The powder coating operation can be realized by rotating the drum. The powder transfer part transfers the powder from the powder coating chamber to the powder storage chamber to realize the powder screening operation. The powder transfer part transfers the powder from the powder storage chamber to the powder coating chamber to realize the powder return operation. Thus, the powder coating device realizes a multifunctional integrated design, reduces the labor intensity of the operator, greatly improves the work efficiency, and at the same time, the structural design is ingenious and the cost is lower.

[0060] In some optional embodiments, the base 120 includes a base 121 and a bracket 122 disposed on the base 121. Both ends of the drum 110 are connected to the bracket 122 and can rotate relative to the bracket 122. The arrangement of the bracket 122 can make the installation of the drum 110 more convenient. The base 121 and the bracket 122 are arranged separately, which can mainly limit the impact of the operation of the drum 110 to the bracket 122, thereby ensuring the stable support of the base 121.

[0061] Continue to refer Figure 2 As shown, in some embodiments, the powder coating device 100 includes a driving assembly 140 for driving the drum 110 to rotate, which is arranged on the base 120, greatly reducing the labor intensity of the operator. The driving assembly 140 includes a driving motor 141 and a transmission assembly 142 connecting the driving motor 141 and the drum 110.

[0062] Furthermore, the transmission assembly 142 includes a first gear 143, a second gear 144 and a transmission belt 145. The first gear 143 is disposed on the drum 110. The second gear 144 is disposed on the base 121, and the transmission belt 145 connects the first gear 143 and the second gear 144.

[0063] The transmission assembly 142 also includes a three-claw coupling 146, and the first gear and the drum are connected by the three-claw coupling 146. The driving motor 141 drives the second gear 144 to rotate, and the first gear 143 and the transmission belt 145 transmit the torque to the drum 110 through the three-claw coupling 146, thereby driving the drum 110 to rotate, and the structure is simple. By controlling the start and stop of the driving motor 141 and the speed to control the number of rotations and the rotation speed of the drum 110, it is ensured that the flour coating effect of the device 100 is basically the same as the effect of manually turning and picking food for flour coating, and the stability of the flour coating quality is ensured.

[0064] In the above embodiment of the present application, a specific implementation of the drive assembly 140 is described. Of course, in some other embodiments, the drive assembly 140 can be redesigned according to actual power requirements and spatial arrangement requirements. Such deformation and redesign should be included in the protection scope of the present application.

[0065] Optionally, the driving assembly 140 further includes a parking structure (not shown). The parking assembly can make the roller 110 park at a specific position when recycling powder, so as to ensure sufficient recovery of powder.

[0066] In the aforementioned embodiment, the driving assembly 140 of the powder coating device 100 uses a driving motor as a power source to realize automatic rotation of the drum 110; admittedly, in certain special circumstances, such as failure or power outage, the powder coating device 100 of the present application also has a manual mode, and the powder coating, powder screening, slag discharge, powder return and other related operations are realized by manually controlling the drum 110.

[0067] like Figures 1 to 3 As shown, the drum 110 includes a shell 119, a powder coating chamber 111 disposed in the shell 119, a powder storage chamber 112, and a powder transfer unit 130 disposed between the powder coating chamber 111 and the powder storage chamber 112. The powder coating chamber 111 is used to accommodate powder and objects to be coated with powder. Optionally, the powder coating chamber 111 is also used to accommodate powder residue sifted out when sifting powder. The powder storage chamber 112 is used to accommodate recycled powder. The powder transfer unit 130 is used to transfer powder between the powder coating chamber 111 and the powder storage chamber 112.

[0068] Optionally, in one embodiment, the powder coating chamber 111 and the powder storage chamber 112 are separated by the powder transfer portion 130. In this way, the powder coating chamber 111 and the powder storage chamber 112 are integrated into the drum 110, which saves installation space, saves materials, and reduces manufacturing costs.

[0069] Furthermore, the powder transfer unit 130 includes a screen 137, and the powder in the powder coating chamber 111 can enter the powder storage chamber 112 through the screen 137 to achieve the function of sieving powder. The screen 137 is provided with a mesh portion 131. The mesh portion 131 is provided with meshes of different mesh sizes set according to actual needs, such as the coarseness of the powder.

[0070] In some embodiments, the mesh portion 131 is a detachable member. The mesh portion 131 can be connected to the screen 137 by magnetic attraction, snap fasteners or other detachable fixing methods, which will not be described in detail here.

[0071] Optionally, in some embodiments, the mesh portion 131 is further provided with a baffle (not shown). The baffle is movably arranged on the screen 137, and can completely cover the mesh of the mesh portion 131. When coating the powder, the baffle covers the mesh portion 131 to prevent the powder from leaking into the powder storage chamber 112; when sifting the powder, the baffle is moved away to allow the powder to pass through the mesh portion 131 smoothly. Such a configuration makes the utilization rate of the powder higher.

[0072] Of course, in other embodiments, the mesh portion 131 may also be provided as a fixed part; when shipped from the factory, the mesh portion 131 of different mesh sizes is set as required.

[0073] Optionally, in some embodiments, grids may be added at other positions on the powder transfer portion 130 to cooperate with the grid portion 131 to sieve powder, thereby improving the powder sieving efficiency.

[0074] The powder transfer unit 130 also includes a powder return channel 132. When returning the powder, the powder in the powder storage chamber 112 can enter the powder coating chamber 111 through the powder return channel 132. Optionally, the powder return channel 132 can include two structural forms of a pipe and an opening, or other structures that can achieve powder conduction. In the illustrated example, the powder return channel 132 takes an open structural form as an example. The powder coating device 100 includes at least two working states: in the first working state, the powder return channel 132 is closed, blocking the powder in the powder coating chamber 111 from entering the powder storage chamber 112; in the second working state, the powder return channel 132 is opened, allowing the powder in the powder storage chamber 112 to enter the powder coating chamber 111. Among them, the first working state can be understood as a powder coating operation, and the second working state can be understood as a powder return operation. There can also be other working states, such as powder screening operations, slag discharge operations, and other operation modes. Such a configuration ensures that the powder wrapping function and the powder return function can be smoothly realized, the powder wrapping chamber 111 forms a closed space when wrapping powder, and the powder wrapping chamber 111 and the powder storage chamber 112 are connected when returning powder. The present application directly returns powder through the above-mentioned powder return channel 132, which has a clever design, a simple structure, and a high powder return efficiency.

[0075] In an application scenario, take the case where the object to be coated with powder is food as an example. The staff can first load the powder material and the food to be coated with powder into the coating chamber 111. Then rotate the drum 110 to start the coating operation, so that the powder material wraps the food to be coated with powder. After the coating is completed, the coated food can be taken out from the coating chamber 111 for standby. Then the powder screening operation can be performed, the drum 110 is rotated to the first position state, and the powder material in the coating chamber 111 is screened to the powder storage chamber 112 through the powder transfer part. After the powder screening operation is completed, the powder return operation can be performed, the drum 110 is rotated to the second position state, and the powder material in the powder storage chamber 112 is returned to the coating chamber 111 through the powder transfer part. It can be understood that the first position state may refer to the position state when the coating chamber 111 is located above the powder storage chamber 112. The second position state may refer to the position state when the coating chamber 111 is located below the powder storage chamber 112. In this way, the multifunctional integrated design of the coating device is realized.

[0076] In some embodiments, the powder return channel 132 is disposed on the screen 137. Optionally, the powder transfer unit may further include a movable member 138. In the first working state, the movable member 138 shields the powder return channel 132; in the second working state, the movable member 138 opens the powder return channel 132. The combination of the powder return channel 132 and the screen 137 and the design of the movable member 138 optimizes the structure and reduces the cost.

[0077] Further, the movable member 138 is movably arranged on the screen 137. The movable member 138 switches between the first position and the second position as the drum 110 rotates to cover or open the powder return channel 132. With such a configuration, the structure is exquisite and easy to implement. It can be understood that the first position can be any position that can cover the powder return channel 132. The second position state can be any position that can open the powder return channel 132, and the present application does not limit this.

[0078] Furthermore, refer to Figure 4 and Figure 5 As shown, the movable part 138 includes a movable leaf 135, which is movably arranged on the screen 137 to achieve a one-way opening effect, and the structure is simple and easy to manufacture. In the first working state, the movable leaf 135 shields the powder return channel 132 to prevent the powder in the powder coating chamber 111 from entering the powder storage chamber 112; in the second working state, the movable leaf 135 opens the powder return channel 132 to allow the powder in the powder storage chamber 112 to enter the powder coating chamber 111. The movable leaf 135 rotates with the drum 110 and switches between the first position and the second position, without the need to set up an additional driving source, saving costs. A limit device 173 is provided on the screen 137 to control the angle between the first position and the second position within a reasonable range.

[0079] In some embodiments, the powder return channel 132 further includes a control device (not shown), which is connected to the movable member 138. In the first working state, the control device controls the movable member 138 to move to the first position to cover the powder return channel 132. In the second working state, the control device controls the movable member 138 to move to the second position to open the powder return channel 132. The control device can enable the movable member 138 to open only when the powder is returned, thereby preventing the movable member 138 from opening and closing continuously following the rotation of the drum 110, thereby reducing noise. The control device can achieve control of the movable member 138 by means of magnetic attraction or the like, and the present application does not limit this.

[0080] In some embodiments, the powder return channel 132 is formed between the screen 137 and the housing 119. Figure 6 As shown, the screen 137 and the housing 119 are arranged movably. That is, in the first working state, the screen 137 is located at the first position, and there is no gap between the screen 137 and the housing 119, so that the powder material is prevented from passing through; in the second working state, the screen 137 moves downward to the second position under the action of gravity, and a powder return channel 132 is formed between the screen 137 and the housing 119 for the powder material to pass through; after the second working state ends, the screen 137 is reset to the first position. At least one of the screen 137 and the housing 119 is provided with a guide device to realize the displacement movement of the screen 137, for example, the housing 119 is provided with a guide groove, the screen 137 is provided with a guide boss, or the housing 119 is provided with a guide boss, and the screen 137 is provided with a guide groove. The housing 119 is provided with a limit device such as a limit protrusion to limit the displacement of the screen 137, so that the screen 137 remains stationary when it moves to the second position.

[0081] Alternatively, if Figure 7 As shown, one end of the screen 137 is hinged to the shell 119 and the other end is a free end. In the second working state, the screen 137 rotates around the hinged end to the second position, and a powder return channel 132 is formed between the free end and the shell 119.

[0082] In other embodiments, the powder transfer unit 130 is not provided with movable parts. Optionally, the powder transfer unit 130 includes a conical through hole, the small opening of the conical through hole is close to the powder coating chamber 111, and the large opening is close to the powder storage chamber 112. In the first working state, the powder in the powder coating chamber 111 is difficult to enter the powder storage chamber 112 through the small opening. In the second working state, the powder in the powder storage chamber 112 can smoothly enter the powder coating chamber 111 from the large opening.

[0083] Continue to refer to Figure 4 and Figure 5The screen 137 includes a bottom plate 133 and a wing 134 connected to the bottom plate 133, and is used to hold powder and food to be coated with powder when the drum 110 is in the initial position. The grid portion 131 is arranged on the bottom plate 133, and the powder return channel 132 is arranged on the wing 134. In some embodiments, there are at least two wings 134, which are arranged on both sides of the bottom plate 133. There is a first set angle α between the bottom plate 133 and the wing 134, ranging from 90 degrees to 180 degrees. Through such a setting, when coating powder, the powder and food in the powder coating chamber 111 roll with the rotation of the drum 110, and when rolling from the bottom plate 133 to the wing 134, they are beaten, thereby improving the coating effect. When sieving powder, the powder can smoothly converge from the wing 134 to the bottom plate 133. When returning powder, the recovered powder slides down to the opening along the inclined wing 134, so that the powder return is smooth.

[0084] In some embodiments, the powder return channel 132 is close to the connection between the wing 134 and the bottom plate 133, and the recovered powder can reach the powder return channel 132 as soon as possible, thereby improving the powder return efficiency and the powder return effect. The present application does not limit the number and structural arrangement of the wing 134. Optionally, the width of the bottom plate 133 is less than the width of the wing 134. In this arrangement, when the powder is returned, the amount of powder accumulated on the bottom plate 133 can be reduced, so that most of the powder falls from the powder return channel 132.

[0085] In some embodiments, the cross-section of the powder coating chamber 111 is a polygon, and such a design can better drive the powder and food to roll. Optionally, the polygon can be a regular polygon, so that when the food rolls from one side of the regular polygon to the other side, the contact between the food and the shell 119 is more complete and uniform, which can improve the powder coating effect. It can be understood that the powder coating chamber 111 includes at least two side walls, and there is a third set angle β between two adjacent side walls, ranging from 90 degrees to 180 degrees, that is, the polygon can be any shape such as a quadrilateral, a pentagon, a hexagon...a circle. In this embodiment, if Figure 8 As shown, the regular polygon is a regular octagon, and the third set angle β is 135 degrees. This setting can achieve the effect of crispy scales, so that the food coated with flour forms a large, light and thin scale effect after frying, and the taste is better. Of course, the regular polygon can also be a regular pentagon, a regular hexagon, a regular heptagon, a regular enneagon, a regular decagon, etc., and this application does not limit this.

[0086] In some embodiments, reference Figures 1 to 3As shown, the screen 137 is a detachable part, which is detachably connected to the shell 119. The shell 119 includes a first shell 113 and a second shell 114, wherein the powder coating chamber 111 is arranged in the first shell 113, and the powder storage chamber 112 is arranged in the second shell 114.

Of course, in other embodiments, the screen 137, the first shell 113, the second shell 114 and the upper cover 116 are connected by other fixing methods such as bolts and nuts, and the present application does not limit this.

[0087] In some embodiments, the powder coating device 100 further includes a slag discharge assembly 150 for discharging powder slag from the powder coating chamber 111. The housing 119 is provided with a slag discharge port 171 (see Figure 3 ). The slag outlet can be set on the screen (see Figure 4 and Figure 5 ), and may also be located at other positions, which is not limited in this application. Fig. 9 As shown, the slag discharge assembly 150 also includes a slag discharge door 158 located at the slag discharge port 171, which can slide up and down, and a door control assembly 159. When it is necessary to discharge the powder slag, the door control assembly 159 controls the slag discharge door 158 to open, so that the powder slag is discharged from the slag discharge port 171 out of the powder coating chamber 111. The powder material in the powder coating chamber 111 will produce powder slag after the food is coated with powder. The powder slag discharge function is provided to ensure that the powder material in the drum 110 can be used normally and the coating effect can be ensured. It can be understood that the powder material that meets the requirements in the powder coating chamber 111 can be sifted into the powder storage chamber 112 through the slag discharge assembly 150, and it can continue to be used as the powder material for the next coating, and the powder slag in the powder coating chamber 111 can be discharged from the powder coating chamber 111.

[0088] Further, the door control assembly 159 includes a telescopic rod 151 and an angle piece 152. A cylinder is provided in the telescopic rod 151.

[0089] After the end of the angle piece 152 away from the telescopic rod 151 rotates upward to press against the push plate 153, it continues to rotate upward, so that the push plate 153 and the slag discharge door 158 slide upward and open, thereby opening the slag discharge door 158. Then, the end of the angle piece 152 away from the telescopic rod 151 rotates downward, and the slag discharge door 158 slides downward under the action of the door closing spring 157 until the push plate 153 and the first limit plate 154 abut, and the slag discharge door 158 is completely closed. In some other embodiments, the door control component realizes the opening and closing of the slag discharge door through other mechanical components and / or control components, which is not limited in this application.

[0090] Optionally, the screen 137 is further provided with a flat plate portion 136 (such as Figure 4 As shown in the figure, the powder slag is located on the bottom plate 133. When the powder slag is discharged, the powder slag moves to the slag discharge port 171 through the flat plate portion 136. In this way, compared with setting the bottom plate 133 entirely as the grid portion 131, the powder slag can roll more smoothly on the flat plate portion 136, and the slag discharge effect is better. The flat plate portion 136 and the grid portion 131 can be distributed on the bottom plate 133 in half, or can be distributed and arranged in other proportions, and this application does not limit this.

[0091] Furthermore, the slag discharge assembly 150 further includes a collection box 170 (eg, Fig.10 As shown in the figure), it is used to receive the discharged powder residue, making it easier to clean it.

[0092] In some embodiments, the slag discharge assembly 150 also includes a lifting assembly (not shown) disposed on the base 120, which is connected to the drum 110 and is used to tilt the drum 110 to a second set angle during slag discharge, so that the powder slag rolls toward the slag discharge door 158 to facilitate slag discharge. The lifting assembly and the slag discharge door 158 are disposed on both sides of the drum 110, so that when slag is discharged, the slag discharge door 158 is located at a lower position relative to other positions of the drum 110. In some embodiments, the lifting assembly is disposed at a connection on one side of the drum and the base, such as at the three-claw coupling 146, to directly lift one end of the drum 110. In other embodiments, the lifting assembly is disposed on the base 121 to tilt the bracket 122 and the drum 110. In other embodiments, the lifting assembly is designed according to requirements, and this application is not limited thereto.

[0093] In some embodiments, the powder coating device 100 further includes a vibration assembly 160 disposed on the base 120 for driving the drum 110 to vibrate.

[0094] Furthermore, the vibration assembly 160 includes a vibration motor 163, and the vibration of the drum 110 is achieved by controlling at least one of the position, direction, vibration frequency or amplitude of the vibration motor 163. How to control the relevant factors specifically depends on the material and application environment of the actual powder. For example, if the powder has high viscosity, a method with higher amplitude and frequency can be adopted. The details will not be repeated here. Such a setting can effectively control the powder screening time, improve the powder screening efficiency, improve the powder screening effect, and greatly avoid the accumulation of powder. During the slag discharge operation, the door control assembly 159 controls the slag discharge door 158 to open, the jacking assembly tilts the drum 110, and the vibration motor 163 drives the bracket 122 and the drum 110 arranged on the bracket 122 to vibrate, and the powder slag rolls from the flat plate 136 to the slag discharge door 158, and is collected in the storage box after being discharged. When the vibration assembly 160 vibrates, powder screening and slag discharge can be performed simultaneously to improve the efficiency. During the powder return operation, after the drum 110 turns over and stops, the vibration assembly 160 can also be operated to improve the powder return effect.

[0095] Furthermore, the vibration assembly 160 also includes a damping spring 161 and a second guide column 162 disposed between the base 121 and the bracket 122. The second guide column 162 is disposed on the base 121 and the bracket 122 in a one-to-one correspondence, and the damping spring 161 is sleeved on the second guide column 162. When the vibration motor 163 vibrates, the damping spring 161 reduces the impact of the vibration on the base 121, so that the base 121 can be stably placed on the operating table, ensuring the smooth operation of the powder coating device 100.

[0096] In some embodiments, the powder coating device 100 further includes a control panel 123 disposed on the base 120, for controlling the powder coating device 100 to perform at least one of powder coating, powder screening, slag discharge, and powder return.
