Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural product processing equipment technology, and in particular to a convenient packaging mechanism for agricultural products. Background Technology
[0002] In the production and distribution of agricultural products, packaging is a key process to ensure product quality and facilitate transportation and storage. Especially for fresh agricultural products such as vegetables and fruits, efficient and damage-free packaging operations directly affect the market value of the products.
[0003] Traditional packaging methods require workers to manually open the packaging bags, put in the agricultural products, and tidy up the bag openings, which is difficult to meet the needs of bulk packaging. Some semi-automatic packaging equipment uses robotic arms or pneumatic devices to open the packaging bags, but the force cannot be adjusted adaptively, which can easily lead to damage to thin packaging bags. In addition, the discharge channel lacks a cushioning design, and the agricultural products are prone to surface damage due to collision and friction during the sliding process, which affects the product quality. Therefore, this utility model proposes a convenient packaging mechanism for agricultural products. Utility Model Content
[0004] The main purpose of this utility model is to provide a convenient packaging mechanism for agricultural products, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A convenient packaging mechanism for agricultural products includes a workbench, a fixed frame fixedly connected to the upper end of the workbench, a motor installed at the upper end of the fixed frame, a lifting mechanism for conveying agricultural products installed at the lower end of the fixed frame, an inner support mechanism for opening the packaging bag installed on the inner side of the fixed frame, and two sets of symmetrical sliding grooves opened on the inner side of the fixed frame.
[0007] Preferably, the lifting mechanism includes a first gear fixedly connected to the output shaft of the motor, two sets of symmetrical second gears meshing with the outer side of the first gear, threaded rods fixedly connected to the inner side of each set of second gears, a fixed disk rotatably connected to the lower end of the first gear, and the outer side of the fixed disk fixedly connected to the fixed frame.
[0008] Preferably, the outer sides of the two sets of threaded rods are connected to a common fixing ring, the inner side of the fixing ring is fixedly connected to a discharge hopper, and the outer side of the discharge hopper is fixedly connected to two sets of symmetrical first T-shaped sliders. The outer sides of the two sets of first T-shaped sliders are respectively slidably connected to the sliding grooves on the inner side of the fixing frame.
[0009] Preferably, the internal support mechanism includes four sets of clamping blocks that are slidably connected to the discharge hopper. Each of the four sets of clamping blocks has a sliding groove at its lower end. Each of the four sets of clamping blocks has a first spring at one end that is far apart from the other end. One end of the first spring is fixedly connected to the clamping block, and the other end of the first spring is fixedly connected to the fixing frame.
[0010] Preferably, the lower end of the clamping block is rotatably connected to a first rotating shaft, the outer side of the first rotating shaft is rotatably connected to a baffle, the lower end of the baffle is provided with a second spring, one end of the second spring is fixedly connected to the baffle, and the other end of the second spring is fixedly connected to a support clamp.
[0011] Preferably, the upper end of the support clamp is fixedly connected to a second T-shaped slider, and the outer side of the second T-shaped slider is slidably connected to the groove at the lower end of the clamp block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device uses a motor-driven gear and threaded rod transmission to raise and lower the discharge hopper. Combined with an internal support mechanism that links springs and sliders, it automatically completes the entire process of opening the packaging bag, filling it, and releasing it. This eliminates the need for manual handling or opening of the bags, reducing labor costs. The internal support mechanism adaptively adjusts the clamping force of the support clamps on the packaging bag using spring force. With four sets of support clamps expanding synchronously, it can smoothly open packaging bags of different sizes, preventing damage caused by uneven force. Simultaneously, the discharge hopper is precisely raised and lowered via a dual guide of threaded rods and T-shaped sliders, reducing collisions and jamming with the internal support mechanism. Furthermore, the smooth inner wall design of the discharge hopper reduces friction damage during the sliding process of agricultural products, making it particularly suitable for fragile agricultural products such as leafy vegetables and berries.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figure 1 - Figure 5 The illustrated convenient packaging mechanism for agricultural products includes a workbench 1, a fixed frame 2 fixedly connected to the upper end of the workbench 1, a motor 3 installed at the upper end of the fixed frame 2, a lifting mechanism 4 for conveying agricultural products installed at the lower end of the fixed frame 2, an inner support mechanism 5 for opening the packaging bag installed on the inner side of the fixed frame 2, and two sets of symmetrical sliding grooves opened on the inner side of the fixed frame 2.
[0023] In this embodiment, the lifting mechanism 4 includes a first gear 41 fixedly connected to the output shaft of the motor 3. Two sets of symmetrical second gears 42 are meshed on the outer side of the first gear 41. Threaded rods 43 are fixedly connected to the inner side of each set of second gears 42. A fixed disk 44 is rotatably connected to the lower end of the first gear 41. The outer side of the fixed disk 44 is fixedly connected to the fixed frame 2.
[0024] Specifically, the first gear 41 rotates under the drive of the motor 3, and through the meshing transmission with the two sets of second gears 42, drives the two sets of threaded rods 43 to rotate synchronously, providing power transmission for the lifting mechanism 4. The fixed plate 44 plays a limiting and fixing role for the first gear 41 and the second gear 42, preventing displacement during rotation and ensuring transmission stability.
[0025] In this embodiment, the outer sides of the two sets of threaded rods 43 are connected to a common threaded ring 45, the inner side of the fixed ring 45 is fixedly connected to a discharge hopper 46, and the outer side of the discharge hopper 46 is fixedly connected to two sets of symmetrical first T-shaped sliders 47. The outer sides of the two sets of first T-shaped sliders 47 are respectively slidably connected to the grooves on the inner side of the fixed frame 2.
[0026] Specifically, the fixed ring 45 converts the rotational motion of the two sets of threaded rods 43 into its own axial lifting motion, thereby driving the discharge hopper 46 to lift synchronously. The discharge hopper 46 serves as a conveying channel for agricultural products, enabling the directional delivery of agricultural products and avoiding disorderly collisions during the falling process. The first T-shaped slider 47 cooperates with the inner sliding groove of the fixed frame 2 to provide guidance for the lifting of the discharge hopper 46, ensuring its stable movement and preventing deviation.
[0027] In this embodiment, the internal support mechanism 5 includes four sets of clamping blocks 51 that are slidably connected to the discharge hopper 46. The lower ends of the four sets of clamping blocks 51 are all provided with sliding grooves. The ends of the four sets of clamping blocks 51 that are far apart are all provided with a first spring 52. One end of the first spring 52 is fixedly connected to the clamping block 51, and the other end of the first spring 52 is fixedly connected to the fixing frame 2.
[0028] Specifically, the clamping block 51 moves outward under the pressure of the downward movement of the discharge hopper 46, initially opening the packaging bag. The first spring 52 absorbs the pressure through its own elastic deformation, providing a buffer for the clamping block 51 to avoid excessive opening force causing damage to the thin packaging bag. At the same time, when the discharge hopper 46 rises, it drives the clamping block 51 to reset, achieving adaptive adjustment.
[0029] In this embodiment, the lower end of the clamping block 51 is rotatably connected to a first rotating shaft 53, the outer side of the first rotating shaft 53 is rotatably connected to a baffle 54, the lower end of the baffle 54 is provided with a second spring 55, one end of the second spring 55 is fixedly connected to the baffle 54, and the other end of the second spring 55 is fixedly connected to a support clamp 56.
[0030] Specifically, the first rotating shaft 53 provides a fulcrum for the baffle 54, allowing the baffle 54 to rotate outward under pressure. The baffle 54 unfolds under the pressure of the discharge hopper 46, further pushing the support clamp 56. The second spring 55 further buffers the pressure through elastic deformation, and works with the support clamp 56 to adjust the opening force of the packing bag to avoid excessive compression and damage. At the same time, when the pressure disappears, it drives the baffle 54 and the support clamp 56 to reset. The support clamp 56 directly contacts and opens the packing bag to ensure that the packing bag opens stably to receive agricultural products.
[0031] In this embodiment, a second T-shaped slider 57 is fixedly connected to the upper end of the support clamp 56, and the outer side of the second T-shaped slider 57 is slidably connected to the groove at the lower end of the clamp block 51.
[0032] Specifically, the second T-shaped slider 57 slides in conjunction with the groove at the lower end of the clamping block 51, providing guidance for the inward and outward movement of the support clamp 56, ensuring the stability of the support clamp 56 during movement, and preventing its deviation from affecting the opening effect of the packaging bag.
[0033] Working principle: When using this equipment, first place the packaging bag at the lower end of the inner support mechanism 5, then start the motor 3 installed on the upper end of the fixed frame 2. The output shaft of the motor 3 drives the first gear 41 to rotate through the rotating shaft. The first gear 41 meshes with the second gear 42, thereby causing the two sets of second gears 42 to drive the threaded rods 43 to rotate synchronously. The fixed plate 44 limits the first gear 41 and the second gear 42 to prevent them from shifting and falling during rotation. The two sets of threaded rods 43 together drive the fixed ring 45 to move downward along the axial direction of the threaded rods 43, thereby causing the discharge hopper 46 to move downward along the inner groove of the fixed frame 2 through the first T-shaped slider 47. As the discharge hopper 46 moves downward, when the outer side of the discharge hopper 46 contacts the clamping block 51, the pressure generated compresses the first spring 52, thereby pushing the clamping block 51 to move outward. When the outer side of the discharge hopper 46 contacts the baffle 54, the pressure further compresses the second spring 55, causing the baffle 54 to rotate outward along the first rotating shaft 53. At the same time, the thrust pushes the support clamp 56 to move outward along the groove at the lower end of the clamp block 51 through the second T-shaped slider 57, opening the packaging bag. At this time, vegetables are put into the inner side of the discharge hopper 46, and the vegetables will fall into the packaging bag along the discharge hopper 46 to complete the packaging. After packaging is completed, the motor 3 is started in reverse, causing the threaded rod 43 to drive the discharge hopper 46 to move upward. When the discharge hopper 46 is misaligned with the baffle 54, the pressure disappears, the second spring 55 returns to its original position, and drives the baffle 54 to rotate in the opposite direction along the first rotating shaft 53 to return to its original position and close. At the same time, the second spring 55 pulls the support clamp 56 to move inward, and the packaging bag falls to the upper surface of the workbench 1. This process is repeated to achieve continuous packaging of vegetables.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
