Description

Technical Field

[0001] This application relates to the field of vacuum packaging equipment technology, and in particular to a seed vacuum packaging device for preventing insect damage. Background Technology

[0002] Both the first and second hoppers employ an inverted conical structure, with the lower end of the first hopper inserted into the upper end of the second hopper. This nested design creates a "funnel effect," causing the seeds to naturally converge to the center and reducing scattering. For example, this can be used in corn seed packaging.

[0003] A search revealed Chinese Patent Publication No. CN218489994U, which discloses a seed vacuum packaging machine, relating to the field of vacuum packaging machine technology. Addressing the problem that current vacuum packaging machines typically have two workstations—one for vacuuming the packaging bag and the other for hot air treatment via an electric heating seal—manual switching between workstations is required, leading to inconvenience and low efficiency. The proposed solution includes: a machine body with a first telescopic cylinder fixedly mounted on it. The piston shaft of the first telescopic cylinder extends into the machine body and is fixedly mounted with a clamping plate. A vacuum pump is fixedly mounted on the bottom side of the clamping plate. This utility model has a reasonable structural design, facilitating the vacuum packaging of seed bags. By using only a single workstation, it eliminates the need for manual bag transfer, improving operation and efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] While simply vacuuming seeds can inhibit insect respiration, it cannot maintain a low-humidity environment for long periods. Especially in humid areas, seeds are prone to absorbing moisture and becoming moldy, making them unsuitable for long-term storage.

[0006] Traditional clamping devices, such as those using rigid pressure plates, are prone to puncturing packaging bags due to uneven pressure, leading to vacuum failure.

[0007] Therefore, in response to the above problems, the applicant provides a seed vacuum packaging device for preventing insect pests. Utility Model Content

[0008] In order to solve the problems mentioned in the background art, this application provides a seed vacuum packaging device for preventing insect pests.

[0009] This application provides a seed vacuum packaging device for preventing insect pests, which adopts the following technical solution:

[0010] A seed vacuum packaging device for preventing insect pests includes a hopper and a U-shaped frame. The hopper is equipped with a cutting mechanism with a cylinder-based insect-proof drying function. The cutting mechanism includes a dual-effect insect-proof desiccant and a cutter. The output end of the cylinder is fixedly connected to the cutter, and the cutter contacts the dual-effect insect-proof desiccant.

[0011] The "U"-shaped frame is equipped with a sliding mechanism that has a cylinder-centered sliding and extrusion function. The sliding mechanism includes a sliding column, which is slidably connected to a crossbeam. A flexible buffer positioning plate is bolted to the crossbeam. The crossbeam is rotatably connected to a crankshaft, and the crankshaft is rotatably connected to a double-shaft connecting rod.

[0012] Optionally, it also includes a feeding cylinder, wherein a hopper is fixedly connected to the outer circumference of the feeding cylinder, the feeding cylinder is located in the frame, a sloping groove is provided on the feeding cylinder, an inclined groove is provided on the hopper, the inclined groove is connected to the sloping groove, and a bag mouth guide groove is provided in the middle of the feeding cylinder.

[0013] Optionally, a vertical plate is fixedly connected to the top surface of the hopper, and one end face of the cylinder input end is fixedly connected to the vertical plate. A pad is fixedly connected to the outer circumferential wall of the discharge cylinder. One side of the pad contacts a dual-effect insect-repellent desiccant, and the cutter cuts two adjacent dual-effect insect-repellent desiccants with cutting lines.

[0014] Optionally, three "U"-shaped frames are fixedly connected from top to bottom in the frame, and a set of central extrusion structures is provided on each of the three "U"-shaped frames.

[0015] Optionally, the three sets of central extrusion structures are divided into an upper clamping component, a lower clamping component, and a positioning component in order from top to bottom. The upper clamping component and the lower clamping component are both composed of sliding columns, crossbeams, clamping plates, crankshafts, dual-shaft connecting rods, and cylinder two. Two parallel sliding columns are fixedly connected to the corresponding two sides of the "U"-shaped frame. Two horizontal crossbeams are slidably connected to the two sliding columns. Clamping plates are bolted to the side of the two crossbeams that are close to each other. A crankshaft is rotatably connected to the four corners of the two clamping plates. The two crankshafts are rotatably connected to the two ends of the dual-shaft connecting rod. The center rod of the dual-shaft connecting rod is fixedly connected to one side of the "U"-shaped frame. Cylinder two is fixedly connected to the inner side of the "U"-shaped frame. The output end of cylinder two is fixedly connected to one of the crossbeams.

[0016] Optionally, the positioning component consists of a sliding column, a crossbeam, a crankshaft, a double-shaft connecting rod, a cylinder, and a flexible buffer positioning plate, with a flexible buffer positioning plate bolted to each of the two crossbeams.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] This invention uses a cylinder to push one of the crossbeams from the input end through the output end. The movement of the crossbeam drives one of the crankshafts, which in turn drives the other crankshaft to rotate. The rotation of the other crankshaft then drives the other crossbeam to slide in the center. The sliding of the two crossbeams in the center causes the two clamping plates or two flexible buffer positioning plates to move in the center. The synchronous sliding of the two clamping plates or two flexible buffer positioning plates can be achieved by a single cylinder.

[0019] This invention utilizes a flexible buffer positioning plate with excellent elasticity and weather resistance. It can deform under pressure and quickly return to its original shape after the pressure is released. At the same time, it can provide uniform support force and prevent the bag from being damaged due to uneven force.

[0020] This invention uses a cylinder to drive a cutter to cut the dual-effect insect-repellent desiccant, which then falls into the packaging bag through an inclined groove and a slant. The dual-effect insect-repellent desiccant uses an oxygen absorber to consume oxygen inside the packaging, inhibiting the respiration of pests, while releasing insect-repellent ingredients to kill insect eggs or larvae. It has both moisture absorption and deoxygenation functions and is suitable for long-term seed storage in high humidity environments. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] This application discloses a seed vacuum packaging device for preventing insect pests.

[0030] like Figure 1-6 As shown, a seed vacuum packaging device for preventing insect pests includes a hopper 2 and an "U"-shaped frame 8. The hopper 2 is equipped with a cutting mechanism with a cylinder 4 for insect prevention and drying. The cutting mechanism includes a dual-effect insect-proof desiccant 6 and a cutter 5. The output end of the cylinder 4 is fixedly connected to the cutter 5, and the cutter 5 contacts the dual-effect insect-proof desiccant 6.

[0031] The "U"-shaped frame 8 is equipped with a sliding mechanism with a cylinder 95 for central sliding and pressing function. The sliding mechanism includes a sliding column 90, which is slidably connected to a crossbeam 91. A flexible buffer positioning plate 10 is bolted to the crossbeam 91. The crossbeam 91 is rotatably connected to a crankshaft 93, which is rotatably connected to a double-shaft connecting rod 94.

[0032] Please see Figure 4 and Figure 5 It also includes a feeding cylinder 1, with a dropping hopper 2 fixedly connected to the outer circumference of the feeding cylinder 1. The feeding cylinder 1 is located in the frame. A sloping groove 100 is opened on the feeding cylinder 1, and an inclined groove is opened on the dropping hopper 2. The inclined groove is connected to the sloping groove 100. A bag opening guide groove is provided in the middle of the feeding cylinder 1. A weighing hopper is connected to the top of the feeding cylinder 1. A bag passes through the bag opening guide groove and is wrapped around the outer wall of the feeding cylinder 1. As the weighing of the bag is completed, the seeds fall with the feeding cylinder 1 and enter the bag. The vacuum packaging machine here is existing technology. The principle of weighing, vacuuming and sealing and the structure implemented are not described in detail here.

[0033] Please see Figure 5 A vertical plate 3 is fixedly connected to the top surface of the hopper 2. One end face of the input end of the cylinder 4 is fixedly connected to the vertical plate 3. A pad 7 is fixedly connected to the outer circumference of the feeding cylinder 1. One side of the pad 7 contacts the double-effect insect-repellent desiccant 6. The cutter 5 cuts two adjacent double-effect insect-repellent desiccants 6. The principle of the double-effect insect-repellent desiccant 6 is the same as that of the preservative added in the packaging machine in the food industry. The various sensors involved are not described in detail here. After the cutter 5 cuts the double-effect insect-repellent desiccant 6, it falls into the packaging paper along with the inclined groove and the inclined groove 100 of the hopper 2. The falling of the double-effect insect-repellent desiccant 6 and the falling of the seeds are synchronized.

[0034] Please see Figure 3 The frame has three "U"-shaped frames 8 fixedly connected from top to bottom, and each of the three "U"-shaped frames 8 is equipped with a set of central extrusion structures 9.

[0035] Please see Figure 1The three sets of centrally located extrusion structures 9 are divided into upper clamping parts, lower clamping parts, and positioning parts in order from top to bottom. Both the upper and lower clamping parts consist of sliding columns 90, crossbeams 91, clamping plates 92, crankshafts 93, dual-shaft connecting rods 94, and cylinders 95. Two parallel sliding columns 90 are fixedly connected to the corresponding sides of the "U"-shaped frame 8. Two horizontal crossbeams 91 are slidably connected to each of the two sliding columns 90. Clamping plates 92 are bolted to the sides of the two crossbeams 91 that are close to each other. A crankshaft 93 is rotatably connected to each of the four corners of the two clamping plates 92. The two crankshafts 93 are rotatably connected to both ends of the dual-shaft connecting rod 94. The central rod of the dual-shaft connecting rod 94 is fixedly connected to one side of the "U"-shaped frame 8. A cylinder 95 is fixedly connected to the inner side of frame 8. The output end of cylinder 95 is fixedly connected to one of the crossbeams 91. The dual-axis connecting rod 94 is used to connect the rotation of two crankshafts 93. The sliding column 90 is used to limit the linear sliding of the crossbeam 91. When the output end of cylinder 95 is pushed from the input end, the output end of cylinder 95 drives one of the crossbeams 91 to move. The movement of the crossbeam 91 drives one of the crankshafts 93 to rotate, and the rotation of the other crankshaft 93 drives the other crossbeam 91 to slide in the center. The sliding of the two crossbeams 91 in the center causes the two clamping plates 92 to move in the center, thereby clamping and fixing the packaging paper. The clamping plates 92 and the flexible buffer positioning plate 10 are made of the same material.

[0036] Please see Figure 3 The positioning component consists of a sliding column 90, a crossbeam 91, a crankshaft 93, a dual-shaft connecting rod 94, a second cylinder 95, and a flexible buffer positioning plate 10. Each of the two crossbeams 91 is bolted with a flexible buffer positioning plate 10. The working principle of the sliding column 90, crossbeam 91, crankshaft 93, dual-shaft connecting rod 94, and second cylinder 95 will not be elaborated here. The flexible buffer positioning plate 10 is made of memory foam material, which has excellent elasticity and weather resistance. It can deform under pressure and quickly return to its original shape after the pressure is released. This characteristic makes memory foam material very suitable for occasions that require adaptive adjustment, such as the side baffle in a seed vacuum packaging device. At the same time, it can provide uniform support force and prevent the bag from being damaged due to uneven force.

[0037] The implementation principle of the seed vacuum packaging device for pest prevention in this application embodiment is as follows:

[0038] The output end of cylinder 2 95 is pushed from the input end, which drives one of the crossbeams 91 to move. The movement of the crossbeam 91 drives one of the crankshafts 93 to rotate, which in turn drives the other crankshaft 93 to rotate. The rotation of the other crankshaft 93 then drives the other crossbeam 91 to slide in the center. The sliding of the two crossbeams 91 in the center causes the two clamping plates 92 or the two flexible buffer positioning plates 10 to move in the center, thereby clamping and fixing the packaging paper. At the same time, the flexible buffer positioning plate 10 is suitable for occasions that require adaptive adjustment, such as the side baffle in the seed vacuum packaging device. It can also provide uniform support force to avoid damage to the bag due to uneven force.

[0039] Cylinder 4 drives the cutter 5 to cut the dual-effect insect-repellent desiccant 6, which then falls into the packaging bag through the inclined groove and slant 100. The dual-effect insect-repellent desiccant 6 uses an oxygen absorber to consume oxygen in the packaging, inhibiting the respiration of pests, while releasing insect-repellent ingredients to kill insect eggs or larvae. It has both moisture absorption and oxygen removal functions and is suitable for long-term seed storage in high humidity environments.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
