Description

Technical Field

[0001] This utility model belongs to the field of anti-mildew technology for fruit stems, and specifically relates to an integrated device for anti-mildew coating and drying of fruit stems. Background Technology

[0002] During post-harvest handling and storage of fruits and vegetables, the fruit stalk (such as in chili peppers) often becomes a major pathway for microbial infection and disease due to its physiological structure. The stalk area is rich in water and nutrients, and its rough surface and numerous pores make it highly susceptible to the growth of molds, bacteria, and other microorganisms, leading to rapid post-harvest rot and spoilage, affecting the fruit's commercial value and shelf life. In recent years, with the development of green preservation concepts, coating-type preservation technology has gradually gained attention. This technology involves coating the fruit stalk with a protective film with antibacterial properties, effectively isolating it from external microbial infection while regulating the fruit's respiration and metabolism, thus extending its shelf life.

[0003] In the existing equipment, excessive preservative solution tends to remain on the surface of the fruit stalk during the coating process. This not only wastes the solution but may also affect the coating effect and preservation performance due to uneven liquid distribution. Traditional coating equipment mostly relies on manual operation to complete the fruit feeding process, which has a low degree of automation, high labor intensity, and is difficult to adapt to the needs of large-scale continuous production. During long-term continuous operation, the liquid level in the coating tank is prone to drop due to consumption, which prevents the fruit stalk from being fully immersed in the coating solution, thus affecting the coating quality.

[0004] Therefore, it is necessary to design an integrated device for anti-mildew coating and drying of fruit stalks to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above technical problems, this utility model proposes an integrated device for anti-mildew coating and drying of fruit stems. This device can avoid the problem of excessive residual preservative solution on the surface of the fruit stems, which would lead to waste of the solution and affect the coating effect and preservation performance due to uneven liquid distribution.

[0006] The technical solution of this utility model is:

[0007] This utility model proposes an integrated device for anti-mildew coating and drying of fruit stems, including a support frame, a coating box fixedly connected to the inner wall of the support frame, a water level sensor fixedly connected to the inner wall of the coating box, and further comprising:

[0008] The coating mechanism includes a motor fixedly connected to the side wall of a support frame. A conveyor roller is fixedly connected to the output end of the motor. A conveyor belt is sleeved on the outer wall of the conveyor roller. An installation hole is provided on the outer wall of the conveyor belt. A C-shaped slide rod is provided on the inner wall of the installation hole. A bearing plate is slidably connected to the outer surface of the C-shaped slide rod. A placement slot is provided on the top of the bearing plate.

[0009] Preferably, the coating mechanism further includes a guide rod fixedly connected to the side wall of the support plate. The outer wall of the guide rod is provided with a guide rail. The outer side of the guide rail is fixedly connected to the inner wall of the support frame. The inner side of the guide rail is provided with a guide groove. The guide rail is configured as a racetrack shape. A recessed part is provided on one side of the guide rail. The recessed part is the fruit stem coating area. The recessed part is connected to the guide groove. The guide rod is slidably connected to the guide groove and the recessed part.

[0010] Preferably, a vibration mechanism is provided on the top of the support plate. The vibration mechanism includes a fixed frame fixedly connected to the top of the support plate. An L-shaped collision rod is slidably connected through the top of the fixed frame. The bottom of the L-shaped collision rod is in contact with the top of the support plate. A reset plate is fixedly connected to the side wall of the L-shaped collision rod. A reset spring is fixedly connected to the bottom of the reset plate. The end of the reset spring away from the reset plate is fixedly connected to the top of the fixed frame.

[0011] Preferably, the vibration mechanism further includes a T-shaped bracket fixedly connected to the inner wall of the support frame, and a reciprocating lifting plate is fixedly connected to the side wall of the T-shaped bracket, with the outer surface of the reciprocating lifting plate in contact with the outer wall of the L-shaped collision rod.

[0012] Preferably, a drain ramp is fixedly connected to the top of the coating box.

[0013] Preferably, the outer wall of the coating box is provided with a liquid replenishment mechanism, which includes a drain pipe connected to the side wall of the coating box, a water pump fixedly connected to the bottom end of the drain pipe, the side wall of the water pump being fixedly connected to the outer wall of the support frame, a suction pipe fixedly connected to the suction end of the water pump, and a liquid storage tank provided on the outer wall of the suction pipe.

[0014] Preferably, a heater is fixedly connected to the inner wall of the support frame, and a fan is fixedly connected to the outer surface of the support frame.

[0015] This utility model has the following advantages and effects compared with the prior art:

[0016] 1. In this integrated anti-mildew coating and drying device for fruit stems, as the support plate continues to move forward with the conveyor belt, the guide rod re-enters the guide groove from the recessed part. At this time, the fruit stem has been separated from the preservative solution stored in the coating tank, completing the initial impregnation coating. Subsequently, the L-shaped collision rod contacts the inclined surface of the reciprocating lifting plate. During the continuous movement of the support plate, the L-shaped collision rod slides upward along the inclined surface and is lifted. When the L-shaped collision rod leaves the area of ​​action of the inclined surface of the reciprocating lifting plate, the return spring releases elastic potential energy, pulling the return plate and the L-shaped collision rod to quickly return downward. During this process, the bottom of the L-shaped collision rod impacts the support plate, causing the support plate to generate mechanical vibration. This vibration causes excess preservative solution adhering to the surface of the fruit stem to fall off and be guided by the drainage inclined plate, eventually flowing back into the coating tank, realizing the recycling and reuse of the coating solution. This effectively improves the coating uniformity, reduces solution loss, and enhances the continuity and stability of equipment operation.

[0017] 2. This integrated anti-mildew coating and drying device for fruit stems allows the supporting plate to continue moving forward with the conveyor belt to the discharge station after the coating and drying processes are completed. At this point, the conveyor belt drives the C-shaped slide bar and the supporting plate to rotate. During the rotation of the supporting plate, the fruits and vegetables detach from the placement slot due to gravity, completing the automatic unloading operation. This not only effectively avoids manual intervention and improves the automation level of the equipment, but also allows the supporting plate to return to its initial position with the conveyor belt after unloading, entering the next round of feeding and processing cycle, forming a complete closed-loop operation process and improving the overall working efficiency and continuous production capacity of the machine.

[0030] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0031] Example 1:

[0032] like Figures 1-7 As shown, this utility model provides an integrated device for anti-mildew coating and drying of fruit stems. The integrated device includes a support frame 101, a coating tank 102 fixedly connected to the inner wall of the support frame 101, and a water level sensor 103 fixedly connected to the inner wall of the coating tank 102. The water level sensor 103 is used to monitor the water level of the coating liquid to ensure the normal operation of the coating process. It also includes:

[0033] The coating mechanism 2 includes a motor 201 fixedly connected to the side wall of the support frame 101. The output end of the motor 201 is fixedly connected to a conveyor roller 202. A conveyor belt 203 is sleeved on the outer wall of the conveyor roller 202. An installation hole 204 is opened on the outer wall of the conveyor belt 203. A U-shaped slide rod 205 is provided on the inner wall of the installation hole 204. A support plate 206 is slidably connected to the outer surface of the U-shaped slide rod 205. A placement slot 26 is opened on the top of the support plate 206. This is designed so that the workers can place the fruits and vegetables to be processed one by one into the placement slot 26 on the top of the support plate 206. The fruits and vegetables are positioned and fixed by the placement slot 26. The fruit stems pass through the bottom of the placement slot 26 and extend downward, preparing for subsequent impregnation and coating.

[0034] The coating mechanism 2 also includes a guide rod 207 fixedly connected to the side wall of the support plate 206. The outer wall of the guide rod 207 is provided with a guide rail 208. The outer side of the guide rail 208 is fixedly connected to the inner wall of the support frame 101. The inner side of the guide rail 208 is provided with a guide groove 209. The guide rail 208 is configured as a racetrack shape. A recessed part 210 is provided on one side of the guide rail 208. The recessed part 210 is the fruit stem coating area. The recessed part 210 is connected to the guide groove 209. The guide rod 207 slides in cooperation with the guide groove 209 and the recessed part 210.

[0035] A vibration mechanism 3 is provided on the top of the support plate 206. The vibration mechanism 3 includes a fixed frame 301 fixedly connected to the top of the support plate 206. An L-shaped collision rod 302 is slidably connected through the top of the fixed frame 301. The bottom of the L-shaped collision rod 302 is in contact with the top of the support plate 206. A reset plate 303 is fixedly connected to the side wall of the L-shaped collision rod 302. A reset spring 304 is fixedly connected to the bottom of the reset plate 303. The end of the reset spring 304 away from the reset plate 303 is fixedly connected to the top of the fixed frame 301. The vibration mechanism 3 also includes a support frame 101 fixedly connected to the support frame. A T-shaped bracket 305 is mounted on the inner wall, and a reciprocating lifting plate 306 is fixedly connected to the side wall of the T-shaped bracket 305. The outer surface of the reciprocating lifting plate 306 is in contact with the outer wall of the L-shaped collision rod 302. This arrangement is designed so that the L-shaped collision rod 302 contacts the inclined surface of the reciprocating lifting plate 306. During the continuous movement of the support plate 206, the L-shaped collision rod 302 slides upward along the inclined surface and is lifted. When the L-shaped collision rod 302 leaves the inclined surface area of ​​the reciprocating lifting plate 306, the return spring 304 releases its elastic potential energy, pulling the return plate 303 and the L-shaped collision rod 302 downward to reset quickly. During this process, the bottom of the L-shaped collision rod 302 impacts the support plate 206. A drain inclined plate 31 is fixedly connected to the top of the coating tank 102. This arrangement is designed so that the drain inclined plate 31 guides the coating liquid, which eventually flows back into the coating tank 102, realizing the recycling and reuse of the coating liquid.

[0036] The outer wall of the coating tank 102 is provided with a liquid replenishment mechanism 4. The liquid replenishment mechanism 4 includes a drain pipe 401 connected to the side wall of the coating tank 102. The bottom end of the drain pipe 401 is fixedly connected to a water pump 402. The side wall of the water pump 402 is fixedly connected to the outer wall of the support frame 101. The suction end of the water pump 402 is fixedly connected to a suction pipe 403. The outer wall of the suction pipe 403 is provided with a storage tank 404. This configuration is such that when the liquid level is detected to be lower than the set threshold, the control system automatically issues a liquid replenishment command and starts the water pump 402. The water pump 402 draws a pre-mixed preservation solution from the storage tank 404 through the suction pipe 403 and delivers it to the inside of the coating tank 102 through the drain pipe 401 to replenish the coating liquid consumed due to continuous operation.

[0037] A heater 501 is fixedly connected to the inner wall of the support frame 101, and a fan 502 is fixedly connected to the outer surface of the support frame 101. This arrangement is so that the fan 502 blows air towards the heater 501, and the heated air forms a stable hot airflow that blows towards the fruit stem, thereby achieving rapid drying of the preservative solution adhering to the surface of the fruit stem.

[0038] In summary, the working principle of the integrated fruit stem anti-mildew coating and drying device of this utility model embodiment is as follows: During use, the water level sensor 103 monitors the liquid level of the preservation solution stored inside the coating tank 102 in real time. When the liquid level is detected to be lower than the set threshold, the control system automatically issues a liquid replenishment command and starts the water pump 402. The water pump 402 draws the pre-mixed preservation solution from the storage tank 404 through the suction pipe 403 and delivers it to the inside of the coating tank 102 through the drain pipe 401 to replenish the coating liquid consumed due to continuous operation and ensure that the coating area always maintains a suitable liquid level.

[0039] In the initial state, the support plate 206 is located at the starting position of the conveyor belt 203, in a waiting position. Workers place the fruits and vegetables to be processed one by one into the placement slot 26 at the top of the support plate 206. The fruits and vegetables are positioned and fixed by the placement slot 26, with the stems extending downwards from the bottom of the slot 26, preparing for subsequent impregnation and coating. Then, the drive motor 201 is started, driving the conveyor roller 202 to rotate, thereby driving the conveyor belt 203 mounted on it to move. The C-shaped sliding rod 205 on the conveyor belt 203 moves synchronously, causing the support plate 206, which is slidably connected to it, to move along a predetermined path towards the coating area. First, the guide rod 207 moves in the guide groove 209 inside the guide rail 208. As the support plate 206 continues to move, the guide rod 207 enters the guide groove 209, thereby causing the support plate 206 to sink as a whole. As the support plate 206 continues to move forward, the fruit stem is immersed in the preservation solution in the coating box 102, achieving uniform coating of the fruit stem area.

[0040] As the support plate 206 continues to move forward with the conveyor belt 203, the guide rod 207 re-enters the guide groove 209 from the recess 210. At this time, the fruit stem has been removed from the preservation solution stored in the coating box 102, completing the initial impregnation coating. Subsequently, the L-shaped collision rod 302 contacts the inclined surface of the reciprocating lifting plate 306. During the continuous movement of the support plate 206, the L-shaped collision rod 302 slides upward along the inclined surface and is lifted. When the L-shaped collision rod 302 leaves the inclined surface action area of ​​the reciprocating lifting plate 306, the return spring 304 releases elastic potential energy, pulling the return plate 303 and the L-shaped collision rod 302 to quickly return downward. During this process, the bottom of the L-shaped collision bar 302 strikes the support plate 206, causing the support plate 206 to vibrate mechanically. This vibration causes the excess preservative solution attached to the surface of the fruit stem to fall off and be guided by the drainage inclined plate 31, eventually flowing back into the coating box 102, realizing the recycling and reuse of the coating solution, effectively improving the coating uniformity, reducing the loss of the solution, and enhancing the continuity and stability of the equipment operation.

[0041] After the coating and vibration drainage treatment of the fruit stem are completed, the support plate 206 continues to move forward along the conveying path. When the support plate 206 moves to the drying area, the heater 501 works to generate heat. At the same time, the fan 502 starts synchronously and blows air towards the heater 501. The heated air forms a stable hot airflow and blows towards the fruit stem to achieve rapid drying of the preservative solution on the surface of the fruit stem.

[0042] After the coating and drying of the fruit stems are completed, the support plate 206 continues to move forward with the conveyor belt 203 to the discharge station. At this time, the conveyor belt 203 drives the C-shaped slide bar 205 to flip with the support plate 206. During the flipping process of the support plate 206, the fruits and vegetables are separated from the placement slot 26 due to gravity, completing the automatic unloading operation. This not only effectively avoids manual intervention and improves the automation level of the equipment, but also allows the support plate 206 to return to the initial position with the conveyor belt 203 after unloading, entering the next round of feeding and processing cycle, forming a complete closed-loop operation process, improving the overall working efficiency and continuous production capacity of the machine.

[0043] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
