Description

Technical Field

[0001] This utility model relates to the field of vegetable packaging technology, specifically a packaging machine for fresh vegetables. Background Technology

[0002] Vegetables are an indispensable part of people's daily diet. They are rich in vitamins, minerals and other nutrients that are beneficial to health. These nutrients are essential for human health, helping us maintain normal physiological functions, enhance immunity and prevent various diseases. After being harvested, vegetables need to go through a series of processing steps, such as washing and sterilization, in order to ensure their safety and hygiene before they can be packaged and presented to the public for consumption.

[0003] Vegetable packaging is an indispensable step in the processing. Packaging prevents vegetables from suffering mechanical damage such as squeezing, collisions, and friction during transportation, storage, and sales, reducing issues like skin breakage and rot. It also isolates vegetables from external dust, bacteria, pesticide residues, and microorganisms, lowering the risk of secondary contamination. Especially during cold chain transportation or market display, packaging prevents vegetables from directly contacting unclean surfaces.

[0004] However, the traditional vegetable packaging method involves a packaging machine head working in conjunction with a conveyor belt. The conveyor belt transports the vegetables to the area below the machine head for bagging. For fresh vegetables, there are inevitably residual leaves, moisture, or soil. If these are not cleaned, the moisture or residual leaves remaining on the surface of the conveyor belt will not only contaminate the vegetables, but also affect their appearance if they are directly put into the packaging bag. Therefore, a packaging machine for fresh vegetables is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one technical problem in the background art, this utility model proposes a packaging machine for fresh vegetables.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a packaging machine for fresh vegetables, comprising a body, a motor and a support leg, wherein the body is fixedly mounted on the support leg, a main transmission mechanism is provided on the support leg, and the motor is fixedly mounted on the support leg;

[0007] The main transmission mechanism includes a main conveyor belt, which is mounted on the support leg and located on one side of the main body. A slave conveyor belt is located below the main body. Both the main conveyor belt and the slave conveyor belt are driven by a motor.

[0008] Baffles are installed on both sides of the main conveyor belt for placing and shielding vegetables;

[0009] The conveyor belt is mesh-like, and the surface of the baffle is provided with an installation groove. A recycling box is fixedly installed in the installation groove by an installation mechanism.

[0010] The main conveyor belt is equipped with a vibration mechanism for cleaning the conveyor belt.

[0011] Preferably, the main transmission mechanism further includes a rotating shaft, on which a transmission wheel is fixedly connected. There are two transmission wheels, and a pair of transmission wheels are symmetrically distributed on the surface of the rotating shaft around the central axis of the conveyor belt. The main conveyor belt is sleeved on the surface of the transmission wheels and connected by gear meshing. The output shaft of the motor passes through the baffle and is rotatably connected, and its end is fixedly connected to the rotating shaft. The surface of the conveyor belt is arc-shaped and tends to converge towards the center.

[0012] Preferably, the vibration mechanism includes a secondary drive belt, a fixed frame is fixedly connected to the surface of the baffle, a top shaft is slidably connected to the surface of the fixed frame via a spring, a secondary magnetic block is fixedly connected to the other end of the top shaft, a main magnetic block is fixedly installed on the surface of the secondary drive belt by screws, the main magnetic block is a soft magnetic strip, and the main magnetic block and the secondary magnetic block are attracted to each other in opposite phases.

[0013] Preferably, there are several top shafts, and the number of magnetic blocks is an integer multiple of the number of top shafts.

[0014] Preferably, the installation mechanism includes a retaining shaft, which is slidably connected to the surface of the recycling box by a spring. A retaining groove is provided on the surface of the installation groove relative to the retaining shaft. A pull rope is fixedly connected to the end of the retaining shaft. A reel is rotatably connected to the surface of the recycling box. One end of the pull rope away from the retaining shaft is fixedly connected to the surface of the reel. The other end of the reel passes through the side wall of the recycling box and is rotatably connected, and a handle is provided at the end.

[0015] Preferably, a rotating plate is fixedly connected to one side of the handle, and the rotating plate is fixedly connected to the end of the recycle box through the scroll. A card is fixedly connected to the surface of the baffle. The card is U-shaped and has an angled opening on its surface.

[0016] Preferably, there are two card shafts, and the pair of card shafts are symmetrically distributed about the central axis of the recycling box.

[0017] The advantages of this utility model are:

[0018] 1. This utility model uses the top shaft to reset and impact the main conveyor belt to generate vibration. Because the main conveyor belt is mesh, the vibration shakes the soil and water on the surface of the vegetables off through the mesh and into the recycling box for collection. This effectively avoids the contamination of vegetables by residual leaves, water or soil, and ensures the cleanliness of the vegetables after packaging.

[0019] 2. This utility model allows for quick disassembly and installation of the recycling box through the combination of handle, roller, and locking block, greatly improving cleaning efficiency. The "U"-shaped card can position the rotating plate to prevent accidental contact. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-3As shown, a packaging machine for fresh vegetables includes a main body 1, a motor and a support leg 5. The main body 1 is fixedly mounted on the support leg 5, the support leg 5 is provided with a main transmission mechanism, and the motor is fixedly mounted on the support leg 5.

[0031] The main drive mechanism includes a main conveyor belt 6, which is mounted on the support leg 5. The main conveyor belt 6 is located on one side of the main body 1, and a slave conveyor belt is located below the main body 1. Both the main drive conveyor belt and the slave conveyor belt are driven by motors.

[0032] Baffle 3 is installed on both sides of the main conveyor belt 6 and is used to place and cover vegetables.

[0033] The conveyor belt is mesh-like, and the surface of the baffle 3 is provided with an installation groove. The recycling box 2 is fixedly installed in the installation groove by an installation mechanism.

[0034] The main conveyor belt 6 is equipped with a vibration mechanism for cleaning the conveyor belt;

[0035] The main transmission mechanism also includes a rotating shaft 8, on which a transmission wheel 9 is fixedly connected. There are two transmission wheels 9, and a pair of transmission wheels 9 are symmetrically distributed on the surface of the rotating shaft 8 around the central axis of the conveyor belt. The main conveyor belt 6 is sleeved on the surface of the transmission wheel 9 and connected by gear meshing. The output shaft of the motor passes through the baffle 3 and is rotatably connected, and its end is fixedly connected to the rotating shaft 8. The surface of the conveyor belt is arc-shaped and the whole tends to converge towards the center.

[0036] The vibration mechanism includes a secondary drive belt 11, a fixed frame 13 fixedly connected to the surface of the baffle 3, a top shaft 7 slidably connected to the surface of the fixed frame 13 via a spring, a secondary magnetic block 15 fixedly connected to the other end of the top shaft 7, a main magnetic block 12 fixedly installed on the surface of the secondary drive belt 11 via screws, the main magnetic block 12 is a soft magnetic strip, the main magnetic block 12 and the secondary magnetic block 15 are opposite phases and attract each other, and a number of top shafts 7 are provided, the number of magnetic blocks being an integer multiple of the number of top shafts 7;

[0037] During operation, the main body 1 and main conveyor belt 6 are started. The vegetables to be packaged are then placed on the main conveyor belt 6. When the motor starts, it first drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the transmission wheel 9, which in turn drives the main conveyor belt 6 to rotate. The vegetables are then moved towards the main body 1 via the conveyor belt until they reach the secondary conveyor belt. The secondary conveyor belt then delivers the vegetables to the area below the main body 1 for packaging. Simultaneously, the rotating shaft 8 drives the secondary transmission belt 11 to rotate. The soft magnetic strips on the surface of the secondary transmission belt 11 also rotate. When the magnetic strips move below the secondary magnetic block 15, the top shaft 7 moves downwards due to the principle of opposite phase attraction. After the magnetic strips pass through... The spring drives the top shaft 7 to reset, and the top shaft 7 impacts the main conveyor belt 6 to generate vibration. Because the main conveyor belt 6 is mesh, the vibration shakes the soil and water on the surface of the vegetables, causing them to fall through the mesh and into the recycling box 2 for collection. This effectively avoids the contamination of vegetables by residual leaves, water, or soil, ensuring the cleanliness of the vegetables after packaging. At the same time, because the conveyor belt tends to converge towards the center, the vegetables will also converge towards the center during vibration, making it easier to put them into the bag. Since the number of magnetic strips is an integer multiple of the number of top shaft 7, moving one magnetic strip position can attract all the auxiliary magnetic blocks 15. The soft magnetic strips fixed by screws are easy to replace later.

[0038] Example 2

[0039] Please see Figure 4-6 As shown in the first embodiment, the installation mechanism of this utility model includes a retaining shaft 22. The retaining shaft 22 is slidably connected to the surface of the recycling box 2 by a spring. A retaining groove 16 is provided on the surface of the mounting groove relative to the retaining shaft 22. A pull rope 21 is fixedly connected to the end of the retaining shaft 22. A scroll 20 is rotatably connected to the surface of the recycling box 2. One end of the pull rope 21 away from the retaining shaft 22 is fixedly connected to the surface of the scroll 20. The other end of the scroll 20 passes through the side wall of the recycling box 2 and is rotatably connected. A handle 17 is provided at the end. A rotating plate is fixedly connected to one side of the handle 17. The rotating plate is fixedly connected to the end of the scroll 20 that passes through the recycling box 2. A card 18 is fixedly connected to the surface of the baffle 3. The card 18 is "U" shaped and has an angled opening on its surface. There are two retaining shafts 22. A pair of retaining shafts 22 are symmetrically distributed about the central axis of the recycling box 2.

[0040] During operation, recycling box 2 requires cleaning after prolonged use. Simply turn handle 17 to rotate the rotating plate. The rotating plate presses against the angled surface of card 18, causing card 18 to deform. Continuing to turn handle 17 will cause it to disengage from card 18. Simultaneously, handle 17 drives the reel 20 to wind up the pull rope 21. The pull rope 21 then pulls the locking pins 22 in a direction that brings them closer together, releasing the locking mechanism of recycling box 2. At this point, recycling box 2 can be pulled out for cleaning. Through the combination of handle 17, reel 20, and locking blocks, recycling box 2 can be quickly disassembled and installed, greatly improving cleaning efficiency. The "U"-shaped card 18 can position the rotating plate to prevent accidental activation.
