Description

Technical Field

[0001] This utility model relates to the field of vegetable packaging technology, and more specifically to a draining device for cold chain vegetable antifreeze packaging. Background Technology

[0002] To ensure the freshness of vegetables, cold chain transportation is generally used. Cold chain transportation requires maintaining a certain low temperature environment throughout the entire process to prevent the vegetables from rotting and spoiling due to temperature increases. After harvesting, vegetables are usually washed, drained, and packaged before transportation. Cold chain transportation involves low temperatures; if vegetables are not drained sufficiently and retain too much moisture, they are prone to freezing and frost damage in the low-temperature environment. Leafy vegetables, due to their layered leaves, are more likely to retain excessive moisture. Existing air-drying and draining machines place vegetables on horizontal or downward-sloping vibrating conveyor screens, with multiple fans installed above the screens. Vibration, tumbling, and blowing remove surface moisture from the vegetables. However, some leafy vegetables, such as rapeseed, have an arc-shaped stem structure and multiple layers, making it difficult for the internal moisture to escape during vibration. This moisture may be ejected during subsequent handling and transportation, remaining inside the packaging bag and unable to drain, causing the outer surface of the vegetable in contact with the packaging bag to freeze and frost damage in the low-temperature environment.

[0003] Therefore, there is an urgent need for a draining device for cold chain vegetable antifreeze packaging that can fully drain the internal moisture of leafy vegetables. Utility Model Content

[0004] In view of this, the present invention aims to provide a draining device for cold chain vegetable antifreeze packaging to at least partially solve the problem of incomplete draining of vegetables in the prior art, which makes them prone to freezing and frost damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A draining device for cold chain vegetable antifreeze packaging includes:

[0007] frame;

[0008] The first conveying mechanism has its discharge end arranged at an upward inclination and mounted on the frame;

[0009] A pressing and conveying mechanism is provided, wherein the conveying direction of the pressing and conveying mechanism is arranged parallel to the first conveying mechanism and is installed on the frame above the first conveying mechanism, and the conveying surfaces of the pressing and conveying mechanism and the first conveying mechanism are close to each other and form a vegetable clamping and conveying channel.

[0010] A vibration mechanism, the output end of which is connected to the first conveying mechanism to drive the first conveying mechanism to vibrate.

[0011] The beneficial effects that this utility model can achieve are as follows: During the conveying process of leafy vegetables, the stems are placed forward. When the vegetables are conveyed to the first conveying mechanism, the first conveying mechanism and the pressing conveying mechanism clamp them together and continue to convey them forward. The vegetables are in a state with the leaves facing down. Under the vibration of the vibration mechanism, the water wrapped in the inner layer of the leafy vegetables flows outward under the action of vibration and gravity, reducing the internal water residue and avoiding insufficient drainage, which may lead to freezing and frost damage in the low-temperature state of subsequent cold chain transportation.

[0012] Preferably, the first conveying mechanism includes a first drive motor, a plurality of first rotating rollers, and a first conveying belt. The first drive motor is mounted on the frame, the plurality of first rotating rollers are rotatably mounted on the frame, and the first conveying belt has a plurality of drainage holes with its discharge end arranged at an upward inclination and connected to the outer surface of the plurality of first rotating rollers. The pressing and conveying mechanism is close to the conveying surface of the first conveying belt and forms a vegetable clamping and conveying channel. The vibration mechanism is installed at the bottom of the conveying surface of the first conveying belt.

[0013] Preferably, the vibration mechanism includes multiple elastic elements, a vibrating plate, and a vibration motor. The multiple elastic elements are arranged perpendicular to the first conveyor belt and one end is mounted on the frame. The vibrating plate is mounted parallel to the first conveyor belt at the other end of the elastic elements, and its upper end is connected to the first conveyor belt. The vibration motor is mounted on the side wall of the vibrating plate. The vibration generated by the vibration motor is transmitted to the first conveyor belt through the vibrating plate, causing the vegetables on the first conveyor belt to vibrate and expel internal moisture.

[0014] Preferably, the vibrating plate includes a base plate and clamping plates. The base plate is arranged parallel to the first conveyor belt and installed at the other end of the elastic member. Two clamping plates are spaced apart on both sides of the top of the base plate along a direction perpendicular to the conveying direction of the first conveyor belt. A groove extending along the conveying direction of the first conveyor belt is formed on the surface of the two clamping plates that are close to each other. The two sides of the first conveyor belt are slidably connected within the groove. This ensures that the first conveyor belt contacts the vibrating plate and vibrates accordingly.

[0015] Preferably, the vibration mechanism further includes a plurality of rollers, which are arranged at intervals along the conveying direction of the first conveyor belt and installed in the chute. The rolling direction of the rollers is all along the conveying direction of the first conveyor belt, and the first conveyor belt is tactilely connected to the surface of the rollers. This reduces friction and allows the first conveyor belt to convey materials smoothly.

[0016] Preferably, the pressing and conveying mechanism includes a second drive motor, multiple second rotating rollers, and a second conveyor belt. The second drive motor is fixed to the frame, and the multiple second rotating rollers are rotatably mounted on the frame above the first conveyor belt. The second conveyor belt is arranged parallel to the conveying direction of the first conveyor belt and is driven onto the surface of the multiple second rotating rollers to form the vegetable clamping and conveying channel between itself and the conveying surface of the first conveyor belt. The second conveyor belt can press against the vegetables while moving synchronously with the first conveyor belt, ensuring that the vegetables adhere to the first conveyor belt and preventing them from sliding down.

[0017] Preferably, the second conveyor belt includes a conveyor belt and multiple pressing belts. The conveyor belts are two in number and spaced apart along a conveying direction perpendicular to the first conveyor belt. Both conveyor belts are connected to the second rotating roller. The multiple pressing belts are spaced apart along the conveying direction of the first conveyor belt, and each pressing belt is connected to two conveyor belts at both ends. The pressing belts press onto the stems of the vegetables, driving the vegetables forward.

[0018] Preferably, the pressing and conveying mechanism further includes a pressing assembly, which includes a fixed seat, a spring, a slide, and a pressure roller shaft. The fixed seat is fixed to the frame above the base plate. The spring is arranged perpendicular to the conveying direction of the first conveyor belt, and one end is fixed to the fixed seat. The frame is provided with a slide rail arranged perpendicular to the conveying direction of the first conveyor belt. The slide is slidably connected to the slide rail and fixedly connected to the other end of the spring. The pressure roller shaft is rotatably mounted on the slide and is rolledly connected to the top of the conveying surface of the conveyor belt. Under the action of the pressure roller shaft, the pressing belt remains in contact with the vegetables, preventing the vegetables from slipping and being damaged during vibration.

[0019] Preferably, it also includes a cooler, which is fixed above the frame and its outlet corresponds to the top of the conveying surface of the first conveyor belt. This accelerates the dewatering efficiency.

[0020] Preferably, it also includes a water receiving tray, which is installed below the first conveyor belt for easy subsequent cleaning.

[0021] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a draining device for cold chain vegetable antifreeze packaging. The first conveying mechanism and the pressing conveying mechanism work together to enable the vegetables to be conveyed upward with the leaves facing down. The vibration mechanism can shake out the water stored inside the vegetables, reducing the residual water inside the vegetables. The pressing component can ensure that the vegetables are pressed on the first conveying mechanism to prevent the vegetables from slipping. Attached Figure Description

[0032] Please see Figures 1-5 This utility model discloses a draining device for cold chain vegetable antifreeze packaging, including: a frame 1, a first conveying mechanism 2, a vibration mechanism 3, and a pressing conveying mechanism 4. The discharge end of the first conveying mechanism 2 is arranged upwardly and installed on the frame 1. The conveying direction of the pressing conveying mechanism 4 is parallel to that of the first conveying mechanism 2 and is installed on the frame 1 above the first conveying mechanism 2, so that the conveying surfaces of the pressing conveying mechanism 4 and the first conveying mechanism 2 are close to each other to form a vegetable clamping and conveying channel. The output end of the vibration mechanism 3 is connected to the first conveying mechanism 2 to drive the first conveying mechanism 2 to vibrate.

[0033] In this embodiment, the stems of the leafy vegetables are placed forward during the conveying process. When the vegetables are conveyed to the first conveying mechanism 2, the first conveying mechanism 2 and the pressing conveying mechanism 4 clamp them together and continue to convey them forward. The vegetables are in a state with the leaves facing down. Under the vibration of the vibration mechanism 3, the water wrapped in the inner layer of the leafy vegetables flows outward under the action of vibration and gravity, reducing the internal water residue and avoiding insufficient drainage, which may lead to freezing and frost damage in the low-temperature state of subsequent cold chain transportation.

[0034] In one specific embodiment, the first conveying mechanism 2 includes a first drive motor 21, a plurality of first rotating rollers 22 and a first conveying belt 23. The first drive motor 21 is mounted on the frame 1, the plurality of first rotating rollers 22 are rotatably mounted on the frame 1, the discharge end of the first conveying belt 23 is arranged at an upward inclination and is drivenly connected to the outer surface of the plurality of first rotating rollers 22, the pressing conveying mechanism 4 and the conveying surface of the first conveying belt 23 are close to each other to form a vegetable clamping and conveying channel, and the vibration mechanism 3 is installed at the bottom of the conveying surface of the first conveying belt 23.

[0035] In one specific embodiment, the vibration mechanism 3 includes multiple elastic elements 31, a vibrating plate 32, and a vibration motor 33.

The vibrating plate 32 is mounted parallel to the first conveyor belt 23 at the other end of the elastic elements 31 and is connected to the lower surface of the first conveyor belt 23. The vibration motor 33 is mounted on the side end face of the vibrating plate 32. The vibration generated by the vibration motor 33 is transmitted to the first conveyor belt 23 through the vibrating plate 32, causing the vegetables on the first conveyor belt 23 to vibrate and shake out the internal moisture.

[0036] In one specific embodiment, the vibrating plate 32 includes a base plate 321 and clamping plates 322. The base plate 321 is arranged parallel to the first conveyor belt 23 and installed at the other end of the elastic member 31. Two clamping plates 322 are installed at intervals on both sides of the top of the base plate 321 along the conveying direction perpendicular to the first conveyor belt 23. A groove 3221 is formed on the plate surface of the two clamping plates 322 that is close to each other, which runs through the conveying direction of the first conveyor belt 23. The two sides of the first conveyor belt 23 are slidably connected in the groove 3221. This ensures that the first conveyor belt 23 is in contact with the vibrating plate 32 and vibrates accordingly.

[0037] In one specific embodiment, the vibration mechanism 3 further includes a plurality of rollers 34, which are arranged at intervals along the conveying direction of the first conveyor belt 23 and installed in the chute 3221. The rolling direction of the rollers 34 is all along the conveying direction of the first conveyor belt 23, and the first conveyor belt 23 is tactilely connected to the surface of the rollers 34. This reduces friction and allows the first conveyor belt 23 to convey materials smoothly.

[0038] In one specific embodiment, the pressing and conveying mechanism 4 includes a second drive motor 41, a plurality of second rotating rollers 42, and a second conveying belt 43. The second drive motor 41 is fixed on the frame 1. The plurality of second rotating rollers 42 are rotatably mounted on the frame 1 above the first conveying belt 23. The second conveying belt 43 is arranged parallel to the conveying direction of the first conveying belt 23 and is driven onto the surface of the plurality of second rotating rollers 42 to form a vegetable clamping and conveying channel between itself and the conveying surface of the first conveying belt 23. The pressure exerted by the second conveying belt 43 on the vegetables should not be too large, just enough to allow the vegetables to move forward along the first conveying belt 23.

[0039] In one specific embodiment, the second conveyor belt 43 includes a conveyor belt 431 and multiple pressing belts 432. The two conveyor belts 431 are arranged at intervals along the conveying direction perpendicular to the first conveyor belt 23. Both conveyor belts 431 are connected to the second rotating roller 42. The multiple pressing belts 432 are arranged at intervals along the conveying direction of the first conveyor belt 23, and each pressing belt 432 is connected to two conveyor belts 431 at both ends. The pressing belts 433 press onto the stems of the vegetables, driving the vegetables forward.

[0040] In one specific embodiment, the pressing and conveying mechanism 4 further includes a pressing assembly 44, which includes a fixed base 441, a spring 442, a slide block 443, and a pressure roller shaft 444. The fixed base 441 is fixed on the frame 1 above the corresponding base plate 321. The spring 442 is arranged perpendicular to the conveying direction of the first conveying belt 23 and one end is fixed to the fixed base 441. The frame 1 is provided with a slide rail 11 arranged perpendicular to the conveying direction of the first conveying belt 23. The slide block 443 is slidably connected to the slide rail 11 and fixedly connected to the other end of the spring 442. The pressure roller shaft 444 is rotatably mounted on the slide block 443, and its rolling surface is rotatably connected to the top of the conveying surface of the conveyor belt 431. Under the action of the pressure roller shaft 444, the second conveying belt 43 can maintain contact with the vegetables, preventing the vegetables from slipping and being damaged during vibration.

[0041] In one specific embodiment, a cooler 5 is also included. The cooler 5 is fixed above the frame 1 and its air outlet corresponds to the conveying surface of the first conveying belt 23 to accelerate the dewatering efficiency.

[0042] In one specific embodiment, a water receiving tray 6 is also included, which is installed below the first conveyor belt 23 for easy cleaning.

[0043] Working principle:

[0044] After washing, the vegetables are placed with their stems facing forward. The first conveying mechanism 2 and the second conveying mechanism 41 operate synchronously. When the vegetables are conveyed to the first conveying mechanism 2, the pressure roller shaft 444 presses the second conveying belt 43 onto the vegetables, ensuring that the vegetables do not slip or tilt and damage the leaves. When the vegetables are conveyed to the vibration mechanism 3, the vibration motor 33 drives the vibration plate 32 to vibrate, which in turn drives the first conveying belt 23 to vibrate. The vegetables also vibrate, causing the water trapped inside to be shaken out and flow towards the leaves along the interlayer of stems and leaves. Under the vibration, the water is released from the vegetables, preventing it from accumulating in the stems and being unable to drain. The released water is blown away by the cool air fan 5 and drips into the water collection tray 6, reducing the amount of water remaining inside the vegetables and improving the drainage efficiency.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
