Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a sine wave push-type puffed food surface coating device and a surface coating process thereof. Background Art

[0002] The coating on the surface of puffed food can not only increase the taste and flavor of the food, but also make the appearance of the food more attractive. The coating on the surface of puffed food is generally coated with coating powder on the surface of the puffed food by a coating machine.

[0003] Chinese patent CN109965329A discloses a surface wrapping process for puffed food based on a sine wave push type, and relates to the field of food processing technology. A stick-shaped food enters a wrapping machine and falls onto a conveyor belt of the wrapping machine. The conveyor belt is powered by a transmission conveying mechanism arranged on the wrapping machine, and is powered by a power supply mechanism arranged on the wrapping machine. When the conveyor belt conveys the stick-shaped food, the motor is turned on, and the output shaft of the motor rotates to drive the transmission driving wheel to rotate and drives the first driven wheel to rotate around its own axis. The movement of the transmission roller causes a particle on the conveyor belt to perform simple harmonic motion up and down. The movement of the transmission roller and the adsorption rod causes the contact interface between the conveyor belt and the transmission roller to always be at a wave crest position, and the contact interface between the conveyor belt and the adsorption rod to always be at a wave trough position. The stick-shaped food is placed at the conveying start end of the conveyor belt and is at a wave trough position between two adjacent transmission rollers.

[0004] Since there are some sticky sauces on the puffed food, after long-term use, the sauce will come into contact with the coating material, and the coating material will adhere to the sinusoidal wave conveying device, and the coating powder will condense into lumps. After long-term use, there will be a lot of condensed coating materials on the conveying plate. When the puffed food rolls onto the condensed powder materials, the condensed coating materials will block the rolling of the puffed food, causing the puffed food to gather on the conveying plate, affecting the transmission of the puffed food. Since the sinusoidal wave moves up and down to drive the puffed food to move, the conveyor belt has peaks and troughs, resulting in poor cleaning effect of the conveyor belt by the traditional cleaning mechanism, and cleaning is more difficult. Summary of the invention

[0005] The object of the present invention is to provide a surface coating device for puffed food based on a sine wave push type and a surface coating process thereof, wherein a cleaning mechanism is installed on a sine wave conveying device, and the cleaning mechanism moves downward to contact a conveying plate, and the cleaning mechanism reciprocates along the conveying direction of the sine wave conveying device to scrape off the condensed coating material on the sine wave conveying device, and then the sine wave conveying device discharges the waste material.

The cleaning mechanism also includes a third rotating mechanism for driving the cleaning disk to rotate, and the cleaning disk can reciprocate along the conveying direction of the sinusoidal wave conveying device.

[0015] A process for coating the surface of puffed food, comprising the device for coating the surface of puffed food based on the sine wave push type in the above scheme,

[0016] S1: The staff puts the puffed food into the feeding device, puts the coating powder into the powder feeding device, the feeding device drops the puffed food onto the sine wave conveying device one by one, and the powder feeding device drops the coating powder onto the sine wave conveying device;

[0017] S2: After the sine wave conveying device is started, the conveying plate will fluctuate up and down, pushing the puffed food;

[0018] S3: After the puffed food is conveyed to the tail end of the sine wave conveying device, the puffed food is collected, and the coating powder enters the coating recovery device and then enters the powder supply device for the next cycle;

[0019] S4: When the puffed food in the feeding device is conveyed, the cleaning device moves the cleaning mechanism, and the cleaning mechanism scrapes off the condensed powder coating material on the conveying plate, and then the condensed powder coating material is transported to the outside of the device by the sine wave conveying device.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the surface wrapping device based on the sine wave push type puffed food and the surface wrapping process thereof have a reasonable structure and have the following advantages:

[0021] (1) The present invention installs a cleaning mechanism on the sinusoidal wave conveying device, and the cleaning mechanism moves downward to contact the conveying plate, and the cleaning mechanism reciprocates along the conveying direction of the sinusoidal wave conveying device to scrape off the condensed coating material on the sinusoidal wave conveying device, and then the sinusoidal wave conveying device discharges the waste material, thereby reducing the risk of the coating powder condensing into a lump, and can further reduce the accumulation of condensed coating material;

[0022] (2) Since the aggregation and blocking of puffed food during the conveying process are reduced, the sine wave push-type wrapping device of the present invention can maintain a stable conveying speed, ensure the continuity and high efficiency of the puffed food during the wrapping process, and improve the production efficiency;

[0023] (3) The cleaning mechanism reciprocates along the conveying direction of the sine wave conveying device, reducing the condensed powder coating and puffed food accumulation on the conveying plate, which helps to keep the production environment clean and hygienic. Through the integrated automatic cleaning system, the device of the present invention greatly reduces the complexity and cost of daily maintenance. The operator can easily complete the cleaning work without too much professional knowledge and skills. At the same time, the high-pressure air blowing method is used to ensure that the surface of the conveying plate is always clean and free of residue, avoiding the accumulation of puffed food;

[0024] (4) Since the sine wave conveying device has a conveying plate that fluctuates up and down, when the sine wave conveying device stops wrapping the material, the conveying plate has crests and troughs, and the traditional cleaning mechanism cannot clean the curved surface between the crests and the troughs, resulting in insufficient cleaning. Therefore, the cleaning mechanism can simulate the sine wave motion form during cleaning, so that the cleaning roller can fully move on the conveying plate, and the curved surface between the crests and the troughs can be easily cleaned, and the cleaning effect is better;

[0025] (5) The conventional conveyor plate uses a conveyor roller and an adsorption rod for rotational motion. The conveyor plate is also subjected to radial force, which may cause the conveyor plate to break after long-term use. The difference between the present invention and the prior art is that the conveyor plate adopts an up and down reciprocating motion structure, that is, the conveyor plate is only subjected to up and down driving force during operation, which solves the problem of the conveyor plate being easily broken.

DETAILED DESCRIPTION

[0043] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] Reference Figure 1-Figure 6 As shown, the present invention provides: a device for coating the surface of puffed food based on a sine wave push type, comprising: a feeding device 100, used for storing puffed food to be coated, and feeding the puffed food one by one; the feeding device 100 comprises a silo 101, a distributing barrel 102 is provided near the bottom of the silo 101 through an axis movement, and a plurality of troughs 1021 for distributing are provided on the distributing barrel 102, and as the distributing barrel 102 rotates, each trough 1021 will pass through the discharge port in turn, and release the puffed food loaded therein to the next process. The design of the material trough 1021 should ensure that the puffed food can be stably stored and released smoothly when needed, avoiding material jamming or releasing multiple puffed foods at the same time. A rotating drive member 103 is fixed on one side of the material bin 101, and the output end of the rotating drive member 103 is connected to a main pulley 1031. The axis at the center of the distributing barrel 102 passes through the material bin 101 and is fixed with a driven pulley 1032. The rotating main pulley 1031 is connected to the driven pulley 1032 through a belt.

[0045] When the rotary drive member 103 is started, its power is transmitted to the driven wheel 1032 through the main pulley 1031, thereby driving the material distribution barrel 102 to rotate. The puffed food falls into the material trough 1021 of the material distribution barrel 102. By adjusting the rotation speed of the rotary drive member 103, the rotation speed of the material distribution barrel 102 can be controlled, thereby adjusting the feeding speed of the puffed food.

[0046] refer to Figure 7 and Figure 8 As shown, the powder supply device 200 is used to store the powder coating material and make the powder coating material fall; the powder supply device 200 includes a powder bin 204, and the powder bin 204 is fixed to the outside of the silo 101, and a screen 202 for screening the material is also arranged inside the powder supply device 200, and a first telescopic driving member 201 is also installed on the top of the powder supply device 200, and the output end of the first telescopic driving member 201 is fixed to the screen 202, and the first telescopic driving member 201 moves the screen 202 up and down for screening the powder coating material, and a plurality of through holes 203 for discharging the coating powder are opened at the bottom of the powder bin 204.

[0047] When the powder supply device 200 starts working, the first telescopic driving member 201 is started, driving the screen 202 to move up and down in the powder bin 204. The vibration and movement of the screen 202 screen the powder coating material in the powder bin 204 to remove impurities or lumps. The screened powder coating material falls through the through hole 203 at the bottom of the powder bin 204. By adjusting the telescopic amount and frequency of the first telescopic driving member 201, the falling speed and amount of the powder coating material can be accurately controlled to meet production needs.

[0048] refer to Fig. 9 The sine wave conveying device 300 is arranged below the feeding device 100 and the powder feeding device 200, and is used to receive the puffed food and the coating powder. The sine wave conveying device 300 is also provided with a conveying plate 305 that fluctuates up and down; the conveying plate 305 is tilted along the conveying direction of the sine wave conveying device 300, and promotes the movement of the puffed food and the coating powder by simulating a sine wave. During the pushing process of the puffed food, the coating powder will adhere to the puffed food; the sine wave conveying device 300 also includes a turntable 302, and the sine wave conveying device 300 also includes a motor for driving the turntable 302, and the turntable 302 is movable through an axis. A connecting rod 303 is provided, and the connecting rod 303 is movably connected to the transmission rod 304 through an axis; the conveying plate 305 is fixed on the supporting plate 301, and the sinusoidal wave conveying device 300 also includes a plurality of lifting rods 306, and rollers are provided at the bottom of the lifting rods 306, and the rollers at the bottom of the lifting rods 306 cooperate with the sinusoidal wave grooves on the moving plate 307, and the tops of the lifting rods 306 are fixed to the bottom of the conveying plate 305 through the cross plates, and when the moving plate 307 reciprocates, the sinusoidal wave grooves on the moving plate 307 cause the lifting rods 306 to reciprocate up and down, thereby causing the conveying plate 305 to exhibit sinusoidal wave motion.

[0049] After the motor is started, it drives the turntable 302 to rotate. The rotational motion of the turntable 302 is converted into the reciprocating motion of the moving plate 307 through the transmission of the connecting rod 303 and the transmission rod 304. The sine wave groove on the moving plate 307 cooperates with the roller at the bottom of the lifting rod 306, so that the lifting rod 306 moves up and down with the reciprocating motion of the moving plate 307. Since the top of the lifting rod 306 and the bottom of the conveying plate 305 are fixed to each other, the conveying plate 305 also presents a sine wave motion. When the puffed food and the coating material are placed on the conveying plate 305, the sine wave motion of the conveying plate 305 will push them forward. During the pushing process, the puffed food will roll and fully contact with the coating material, so that the coating material adheres to the puffed food.

[0050] refer to Figure 1 , Figure 5 and Figure 6 As shown, the coating material recovery device 400 is used to collect the coating material and convey the coating material to the feeding device 100 for circulation; the coating material recovery device 400 includes a recycler 401, and a sieve plate 402 is also installed in the recycler 401, and the sieve plate 402 is used to filter the agglomerated coating material; the recycler 401 is also provided with a discharge port, the discharge port is connected to the coating material recovery device 400, and the top of the coating material recovery device 400 is interconnected with the powder feeding device 200.

[0051] The cleaning device 500 is used to clean the sticky coating material on the sine wave conveying device 300; the cleaning device 500 is provided with a cleaning mechanism, and a space for the puffed food to pass through is formed between the cleaning mechanism and the sine wave conveying device 300. The cleaning mechanism is also equipped with a lifting mechanism for driving the cleaning mechanism to move up and down. When it is necessary to clean the sine wave conveying device 300, the cleaning mechanism moves downward until it contacts the surface of the sine wave conveying device 300, and the cleaning mechanism moves to loosen and clean the agglomerated coating material on the sine wave conveying device 300. When it is not necessary to clean the sine wave conveying device 300, the cleaning mechanism rises, and the cleaning mechanism rises and forms a space for the puffed food to pass through with the sine wave conveying device 300.

[0052] refer to Figure 3 , Figure 4 and Figure 5 As shown, the cleaning mechanism has a cleaning roller 5031, and the cleaning roller 5031 has a brush. The cleaning mechanism also includes a first rotating mechanism for driving the cleaning roller 5031 to rotate. The cleaning roller 5031 can reciprocate along the movement direction of the puffed food on the sinusoidal wave conveying device 300. The cleaning device 500 includes a first linear motion mechanism for driving the cleaning roller 5031 to reciprocate. The first linear motion mechanism can be a cylinder, an electric cylinder, or other mechanisms that can perform linear motion.

[0053] In the first embodiment, the cleaning mechanism includes a connecting frame 501, and the connecting frame 501 extends into the supporting plate 301 through the transverse groove on the supporting plate 301, and a movable rod 5011 is also provided on the connecting frame 501, and the movable rod 5011 is sleeved with a spring 5012 on the upper part of the connecting frame 501, and a movable frame 5014 is fixed to the bottom of the movable rod 5011, and the two ends of the movable frame 5014 are movably provided with limit rollers 5013, and the limit rollers 5013 are movably provided on the guide groove 3011.

When cleaning the condensed blocky coating powder on the conveying plate 305, the second telescopic driving member 504 causes the connecting shaft 505 to rise, so that the second bevel gear 506 meshes with the third bevel gear 507, and the second bevel gear 506 meshes with the first bevel gear 5021. In this way, the power of the distributing barrel 102 will be transmitted to the lead screw 502. When it is not cleaned, the second bevel gear The first bevel gear 5021 is separated from the second bevel gear 506, and the second bevel gear 506 is separated from the first bevel gear 5021. In this way, the cleaning roller 5031 in the cleaning mechanism does not reciprocate, so as to avoid the movement of the cleaning roller 5031 affecting the puffed food wrapping when wrapping the food. When the lead screw 502 rotates, the lead screw 502 causes the connecting frame 501 to reciprocate in the conveying direction of the sine wave conveying device 300. At this time, since the limit roller 5013 is movably provided on the movable frame 5014, the limit roller 5013 moves in the guide groove 3011. The movable frame 5014 can move up and down in a sinusoidal wave shape, and the spring 5012 can reset the movable frame 5014, so that when the conveying plate 305 stops running, the lifting mechanism makes the cleaning roller 5031 contact with the conveying plate 305, and the condensed block-shaped coating powder on the conveying plate 305 is scraped off by the rotation of the cleaning roller 5031.

At the jet head 508, the high-pressure gas is ejected at a high speed to form a strong airflow. This airflow directly acts on the condensed powder coating material on the sine wave conveying device 300 to loosen or disperse it. Subsequently, the loose powder coating material can be removed from the sine wave conveying device 300 by mechanical scraping or natural falling.

[0068] A process for coating the surface of puffed food, comprising the device for coating the surface of puffed food based on a sine wave push method in the above scheme,

[0069] S1: The staff puts the puffed food into the feeding device 100 and the coating powder into the powder feeding device 200. The feeding device 100 drops the puffed food onto the sinusoidal wave conveying device 300 one by one, and the powder feeding device 200 drops the coating powder onto the sinusoidal wave conveying device 300.

[0070] S2: After the sine wave conveying device 300 is started, the conveying plate 305 will fluctuate up and down to push the puffed food. During the pushing process of the puffed food, the puffed food will rotate on the coating powder, so that the coating powder will stick to the puffed food;

[0071] S3: After the puffed food is conveyed to the tail end of the sine wave conveying device 300, the puffed food is collected, and the coating powder enters the coating powder recovery device 400 and enters the powder supply device 200 for the next cycle;

[0072] S4: After the puffed food in the feeding device 100 is conveyed, the cleaning device 500 moves the cleaning mechanism, which scrapes off the condensed coating material on the conveying plate 305, and then the condensed coating material is transported to the outside of the device by the sine wave conveying device 300.
