TECHNICAL FIELD
[0001] The present application relates to the technical field of food processing conveying equipment, in particular to a food rotating processing assembly line. BACKGROUND
[0002] In the field of food processing, rotating powder coating is a key process for pretreatment of fried foods (such as fried chicken, potato cakes, etc.), which uniformly adheres the coating powder to the surface of the food through the centrifugal rotation of the equipment, forms a crisp shell, and directly affects the taste and appearance of the finished product. The current mainstream centrifugal rotating powder coating equipment relies on centrifugal force to achieve powder coating, but there are significant technical defects in actual application. Under the action of centrifugal force, food is easily thrown to the edge of the inner wall of the equipment and accumulated on the wall, on the one hand, which destroys the all-around uniform contact between food and coating powder, resulting in local areas of food missing coating powder or uneven powder layer thickness, and the missing powder area is easy to be scorched and oil-absorbed after frying, and the thick powder area is easy to be undercooked and hard, which seriously affects the product quality consistency; on the other hand, the food accumulated at the edge is easily stuck together due to the mutual extrusion and the adhesion of the moisture, oil and other sticky substances carried on the surface of the food, not only causing waste of raw materials, but also causing uneven heating during subsequent processing of the stuck food, further causing problems such as incomplete frying and poor taste, and the accumulation also disturbs the distribution of the coating powder in the equipment, exacerbating the coating defects. In the prior art, although attempts have been made to improve by adjusting the equipment speed, adding simple stirring structures, etc., it is difficult to effectively balance the centrifugal force and the dispersion requirement of food, and the core problem of food accumulation on the edge of the wall cannot be fundamentally solved, there is a lack of protective mechanism that can push the edge food to the middle, and it is difficult to balance the uniformity of the coating powder and the anti-sticking effect, so it is necessary to propose a more optimal technical solution to make up for the above shortcomings.

DETAILED DESCRIPTION
[0019] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.
[0020] Embodiment: please refer to Figures 1 to 14 ; A food rotating processing assembly line, comprising a frame 1, a powder wrapping box 4 rotatably arranged on the frame 1, a control box 12 and a bearing frame 19 sequentially and fixedly arranged on the frame 1, a support frame 13 fixedly arranged on the top of the control box 12, a lifting conveyor belt 14 obliquely arranged on the support frame 13 and the bearing frame 19, and a feeding conveyor belt 11 arranged beside the lifting conveyor belt 14, further comprising an edge pushing mechanism, a gathering mechanism and a vibrating mechanism, the edge pushing mechanism comprising an annular air bag 20 coaxially and fixedly arranged on the inner wall of the powder wrapping box 4 and an air storage tank 29 fixedly arranged on the frame 1, the air storage tank 29 being used for intermittently sending air to the annular air bag 20, the gathering mechanism comprising a material pushing belt 35 arranged above the powder wrapping box 4 and a plurality of equally spaced soft pushing plates 36 arranged on the material pushing belt 35, and the vibrating mechanism comprising a drainage plate 17 connected to the support frame 13 through a torsional spring and a vibrating output end for driving the drainage plate 17 to vibrate, the vibrating output end being in transmission connection with the powder wrapping box 4.
[0021] It should be noted that the material to be coated is conveyed to the coating disc by the feeding conveyor belt 11, and the bottom of the frame 1 is provided with a driving device for driving the coating drum 4 to rotate, which can be a motor. In addition, the lifting conveyor belt 14 is a grid conveyor belt, which facilitates the drainage of excess powder. This is a mature existing technology and will not be described in detail here. During operation of the device, the operator first pours an appropriate amount of coating powder into the coating drum 4, and then the driving device drives the coating drum 4 to rotate, while the feeding conveyor belt 11 sends the material to be coated into the coating drum 4. Then, as the coating drum 4 rotates, the material is rolled and coated with powder under the action of centrifugal force, and is gathered to the edge of the inner wall of the coating drum 4. At the same time, the gas storage tank 29 intermittently supplies gas to the annular air bag 20, causing the annular air bag 20 to start to expand intermittently, and then pushing the material gathered at the edge of the inner wall of the coating drum 4 to the center of the coating drum 4, preventing the material from accumulating and causing uneven coating. At the same time, the stirring belt 35 in the gathering mechanism also starts to operate, and the stirring belt 35 rotates and drives the material pushed by the annular air bag 20 to gather again to the center of the coating drum 4 through the stirring soft plate 36 arranged thereon, causing the material to roll again. This avoids material accumulation while allowing the material to roll again, further ensuring uniform coating. Then, the coated material is conveyed by the lifting conveyor belt 14, and at this time, the excess powder falls onto the drainage plate 17. At this time, the vibration output end of the vibration mechanism operates synchronously, driving the drainage plate 17 to vibrate, preventing the powder from accumulating on the inclined drainage plate 17, ensuring that the powder can flow back into the coating drum 4 again, avoiding waste, and then the coated material is conveyed to the next ring frame, and the above process is repeated to ensure continuous operation of the device, protect the uniformity of the coating, and improve the yield.
[0022] In order to ensure that the coating drum 4 can rotate more stably, the following features are also provided: The bottom of the coating drum 4 is coaxially and fixedly connected with a connecting ring 3, and a limiting ring 2 is fixedly arranged on the frame 1, and the limiting ring 2 is coaxial with the connecting ring 3 and is in sliding fit.
[0023] When the coating drum 4 is driven to rotate by the bottom driving device, the connecting ring 3 at the bottom of the coating drum 4 will be embedded in the annular groove of the limiting ring 2 and rotate synchronously with the coating drum 4. The coaxial sliding fit of the limiting ring 2 and the connecting ring 3 can limit the coating drum 4 in the radial direction, effectively limiting the horizontal deviation and shaking of the coating drum 4 during rotation, avoiding problems such as position deviation when the annular air bag 20 pushes the material, and the driving of the stirring belt 35 and the coating drum 4 is out of sync, and forming a double-stable structure of the coating drum 4 with the driving device to ensure the stability of the device during the entire coating process.
[0024] In order to show how the gas storage tank 29 supplies gas to the annular air bag 20, the following features are also provided: The edge pushing mechanism further comprises a transition air ring 5 coaxially fixed on the inner wall of the powder wrapping box 4, a transition ring seat 6 coaxially fixed on the outer wall of the powder wrapping box 4, an adapter ring box 10 fixed on the rack 1 through a support, and a pump 30 arranged on the gas storage tank 29. The pump 30 is in transmission connection with the powder wrapping box 4. The transition ring seat 6 is in internal communication with the transition air ring 5. The adapter ring box 10 is coaxial with the transition ring seat 6 and is dynamically sealed. The transition air ring 5 is in internal communication with the annular air bag 20.
[0025] When the gas storage tank 29 supplies gas to the annular air bag 20, the pump 30 will operate under the transmission action of the powder wrapping box 4, and the gas in the gas storage tank 29 is pressed into the adapter ring box 10. Since the adapter ring box 10 and the transition ring seat 6 are coaxial and dynamically sealed (rotary sealing can be achieved through a sealing ring), the gas can smoothly enter the transition ring seat 6 from the adapter ring box 10, and then pass through the internal communication channel of the transition ring seat 6 and the transition air ring 5, and finally be delivered to the annular air bag 20 connected with the transition air ring 5. This structure ingeniously solves the problem of gas delivery and sealing under the rotating state of the powder wrapping box 4, and ensures that the gas flow is stably transmitted to the annular air bag 20, providing a continuous gas source for its intermittent expansion.
[0026] In order to show the connection relationship between the powder wrapping box 4 and the pump 30, the following features are further provided: The edge pushing mechanism further comprises a bearing seat 23 fixed on the rack 1, a bearing shaft 24 rotatably arranged on the bearing seat 23, a bearing gear 25 coaxially fixed on the bearing shaft 24, an adapter rod 26 arranged on the bearing gear 25, a positioning support 27 arranged beside the bearing seat 23 and fixedly connected with the rack 1, a sliding strip plate 28 slidingly arranged on the positioning support 27, and a transmission gear ring 9 coaxially fixed on the outer wall of the powder wrapping box 4. The bearing gear 25 is in meshing connection with the transmission gear ring 9. One end of the adapter rod 26 is in rotational connection with the sliding strip plate 28, and the other end is in eccentric rotational connection with the bearing gear 25. The end of the sliding strip plate 28 away from the adapter rod 26 is connected with the pump 30.
[0027] When the powder wrapping box 4 rotates, the transmission gear ring 9 on the outer wall of the powder wrapping box 4 will rotate synchronously, thereby driving the bearing gear 25 in meshing connection therewith to rotate around the bearing shaft 24. Since one end of the adapter rod 26 is eccentrically connected to the bearing gear 25, the bearing gear 25 will pull the sliding strip plate 28 to make reciprocating linear motion under the guidance of the positioning support 27 when the bearing gear 25 rotates. The end of the sliding strip plate 28 away from the adapter rod 26 is connected with the piston of the pump 30. The reciprocating motion of the sliding strip plate 28 can drive the piston of the pump 30 to alternately compress and reset, thereby realizing that the pump 30 rotates synchronously with the powder wrapping box 4 to supply gas to the gas storage tank 29 and the adapter ring box 10 without the need for an additional power source, and ensuring that the gas supply action is accurately matched with the rotation rhythm of the powder wrapping box 4.
[0028] In order to show how the annular air bag 20 is intermittent inflation, it is also provided with the following features: The edge dial mechanism also includes a number of annularly arranged gas pipes 21 on the annular air bag 20, a one-way valve 22 coaxially fixed in each gas pipe 21, a gas supply pipe 31 and a gas return pipe 32 fixed on the gas storage tank 29, the other end of the gas supply pipe 31 and the gas return pipe 32 are communicated with the adapter ring box 10, and the flow directions of adjacent one-way valves 22 are opposite.
[0029] When the air pump 30 pushes the piston to compress the gas, the gas enters the adapter ring box 10 through the gas supply pipe 31, at this time the one-way valve 22 in the corresponding gas pipe 21 of the gas supply pipe 31 (the flow direction is towards the annular air bag 20) is opened, and the one-way valve 22 in the corresponding gas pipe 21 of the gas return pipe 32 (the flow direction is towards the gas storage tank 29) is closed, the gas smoothly enters the annular air bag 20 to make it expand and push the edge material; when the air pump 30 piston resets to inhale, a negative pressure is formed in the adapter ring box 10, the one-way valve 22 corresponding to the gas return pipe 32 is opened, and the one-way valve 22 corresponding to the gas supply pipe 31 is closed, the gas in the annular air bag 20 flows back to the gas storage tank 29 through the gas return pipe 32, and the annular air bag 20 shrinks and resets; through the alternating on-off of the two groups of opposite direction one-way valves 22, combined with the reciprocating action of the air pump 30, the intermittent expansion and contraction of the annular air bag 20 is realized, and the material pushing frequency is accurately controlled In order to ensure that the material after being wrapped with powder can be smoothly sent away by the lifting conveyor belt 14, the following features are also provided: The bottom end of the lifting conveyor belt 14 is fixedly provided with an adapter plate 15, the end of the adapter plate 15 away from the lifting conveyor belt 14 is rotatably provided with a material blocking arc plate 16 through a torsional spring, and the material blocking arc plate 16 is attached to the annular air bag 20.
[0030] After the material in the wrapping powder round box 4 is wrapped with powder, the wrapping powder round box 4 is rotated to the bottom end of the lifting conveyor belt 14, the adapter plate 15 can build a transition channel between the wrapping powder round box 4 and the lifting conveyor belt 14 to prevent the material from falling; at the same time, the material blocking arc plate 16 is always attached to the outer wall of the annular air bag 20 under the elastic force of the torsional spring, which not only prevents the material from leaking out of the gap between the inner wall of the wrapping powder round box 4 and the adapter plate 15, but also can slightly rotate with the outer wall of the annular air bag 20 (the torsional spring adapts to the deformation) when the annular air bag 20 is intermittently inflated, avoiding hindering the action of the annular air bag 20, ensuring that the material is stably guided to the lifting conveyor belt 14, and reducing the loss and retention of the material during the conveying process.
[0031] In order to show the detailed structure of the gathering mechanism, the following features are also provided: The gathering mechanism also includes a mounting plate 33 fixedly arranged on the rack 1 and a containing box 34 fixedly arranged on the mounting plate 33, a material pushing belt 35 is arranged in the containing box 34, and the material pushing soft plate 36 is made of food-grade silicone material.
[0032] It should be noted that the containing box 34 is provided with a driving device for driving the stirring belt 35 to rotate; during the operation of the device, as the annular air bag 20 is intermittently inflated, the material is pushed away from the inner wall of the powder-coated round box 4, and then under the rotation of the stirring belt 35, the material is further stirred to the center of the powder-coated round box 4 through the stirring soft plate 35, and the material is rolled to ensure uniform powder coating. It should be noted that the stirring soft plate 35 only assists the rolling of the material, and is not directly used to shovel the material.
[0033] In order to show the detailed structure of the vibration mechanism, the following features are further provided: The vibration mechanism further comprises a U-shaped frame 41 fixedly arranged on the bearing frame 19, a supporting rod 42 slidably arranged on the U-shaped frame 41, a roller frame 43 fixedly arranged at the top end of the supporting rod 42, a touch wheel 44 rotatably arranged on the roller frame 43, a touch plate 45 fixedly arranged at the bottom end of the supporting rod 42, two guide rods 46 arranged in a symmetrical state on the U-shaped frame 41, a limiting frame 47 arranged below the U-shaped frame 41 and fixedly connected with the bearing frame 19, a supporting shaft 48 rotatably arranged on the limiting frame 47, a cam 49 coaxially fixedly arranged on the supporting shaft 48, a gear frame 50 fixedly arranged on the limiting frame 47, an engagement gear 51 and a reversing gear 52 rotatably arranged on the gear frame 50, and a connecting gear 53 coaxially fixedly connected with the reversing gear 52. The connecting gear 53 is engaged with the transmission gear ring 9, the bottom ends of the two guide rods 46 penetrate through the U-shaped frame 41, the top ends are fixedly connected with the roller frame 43, and the supporting shaft 48 is coaxially fixedly connected with the engagement gear 51.
[0034] The touch wheel 44 is the vibration output end of the vibration mechanism.
[0035] When the powder-coated round box 4 rotates to drive the transmission gear ring 9 to rotate, the transmission gear ring 9 drives the connecting gear 53 to rotate, the connecting gear 53 changes the transmission direction through the reversing gear 52 and the engagement gear 51, and then the supporting shaft 48 and the cam 49 rotate synchronously; during the rotation of the cam 49, the protruding part of the cam 49 periodically pushes the touch plate 45, drives the supporting rod 42 to slide up and down along the U-shaped frame 41, and the guide rods 46 ensure stable sliding; the touch wheel 44 (i.e. the vibration output end) on the roller frame 43 at the top end of the supporting rod 42 slides up and down with the supporting rod 42, repeatedly touches the bottom of the drainage plate 17; under the cooperation of the torsional spring, the drainage plate 17 vibrates with the touch of the touch wheel 44, scatters the drained powder and guides the flow back. The whole structure realizes the synchronous linkage of the vibration action and the rotation of the powder-coated round box 4 through the gear transmission and the cam 49 mechanism, without the need for an additional vibration power source.
[0036] In order to ensure that the drained powder can fall more smoothly from the drainage plate 17 into the powder-coated round box 4, the following features are further provided: The drainage plate 17 is uniformly provided with a plurality of guide grooves 18 along the width thereof.
[0037] When the excess powder drained from the lifting conveyor belt 14 falls onto the drainage plate 17, the guide grooves 18 can guide the powder, avoiding the powder from spreading or staying on the surface of the drainage plate 17 at will; especially when the vibration mechanism drives the drainage plate 17 to vibrate, the powder will flow into the powder-coated round box 4 along the groove direction of the guide grooves 18, reducing the accumulation of powder at the edge of the drainage plate 17, and the guide grooves 18 can also reduce the contact area between the powder and the drainage plate 17, further reducing the adhesion of the powder, ensuring that the drained powder flows back into the powder-coated round box 4 efficiently and smoothly, and improving the utilization rate of the powder.
[0038] The working principle of the device is as follows: when the device is started, the driving device at the bottom of the rack 1 drives the powder-coated round box 4 to rotate, and the feeding conveyor belt 11 synchronously conveys the material to be coated with powder into the powder-coated round box 4. Under the action of centrifugal force, the material is gathered to the edge of the inner wall of the powder-coated round box 4, and at this time, the edge stirring mechanism is started: the bearing disc 25 engaged with the transmission gear ring 9 on the outer wall of the powder-coated round box 4 rotates with the round box, and through the link rod 26, it pulls the sliding strip plate 28 on the positioning support 27 to make reciprocating motion, and then drives the air pump 30 on the gas storage tank 29 to act; the air pump 30 pressurizes the gas into the link ring box 10 on the rack 1, and the link ring box 10 and the adapter ring seat 6 on the outer wall of the powder-coated round box 4 keep coaxial dynamic sealing, the gas enters the adapter gas ring 5 on the inner wall of the powder-coated round box 4 through the adapter ring seat 6, and finally is delivered to the annular air bag 20; the one-way valve 22 corresponding to the air supply pipe 31 and the air return pipe 32 is alternately opened and closed, so that the annular air bag 20 is intermittently inflated, and the material accumulated at the edge is pushed to the center of the round box, breaking the accumulation state caused by centrifugal force. At the same time, the stirring belt 35 in the driving containing box 34 is driven to operate; the stirring soft plate 36 on the belt pushes the material gathered to the center of the annular air bag 20 again, so that the material continuously tumbles, ensuring that the material is in full contact with the powder in the powder-coated round box 4, and ensuring the uniformity of powder coating. The material after coating is rotated to the bottom end of the lifting conveyor 14 with the coating box 4, the transition channel of the coating box 4 and the lifting conveyor 14 is built by the abutment plate 15, the end of the abutment plate 15 is attached to the blocking material arc plate 16 connected by the torsion spring and the annular air bag 20, which not only prevents the material from leaking out of the gap, but also can adaptively rotate with the annular air bag 20; the material is stably guided to the inclined lifting conveyor 14, the grid grid-shaped conveyor belt drains the excess powder on the surface of the material, and the powder falls into the drainage plate 17 below. At this time, the vibration mechanism works synchronously: the transmission gear ring 9 drives the cam 49 on the limiting frame 47 through the connecting gear 53 and the reversing gear 52, the cam 49 periodically pushes the contact plate 45, drives the supporting rod 42 to slide up and down along the U-shaped frame 41, the guide rod 46 ensures stable sliding, and the contact wheel 44 at the top of the supporting rod 42 repeatedly touches the drainage plate 17; the drainage plate 17 vibrates under the cooperation of the torsion spring, and the flow guide groove 18 on the plate guides the powder back to the coating box 4, realizing the recycling of the powder. In the whole process, each mechanism is linked through the transmission gear ring 9 and the coating box 4, without the need for additional power source, ensuring the continuous and stable operation of the equipment.
