Description

Technical Field

[0001] This utility model relates to the field of pesticide packaging technology, and more specifically, to a pesticide granule packaging device. Background Technology

[0002] Granules are a solid dosage form obtained by mixing and granulating the active pharmaceutical ingredient with carriers, binders, dispersants, wetting agents, stabilizers and other adjuvants. Its performance requirements mainly include fineness, uniformity, storage stability, hardness and disintegration. Granules have the largest particle size among solid dosage forms, with a diameter of 300-1700 μm. They have the advantages of being easy to use, having low outward diffusion and long-lasting efficacy. Currently, floating granules, microparticles and microcapsules have been developed from granules.

[0003] Common pesticide granule packaging equipment can only package granules, but lacks the function of adjusting the opening of the packaging bag. In the actual packaging process, multiple external support rods are needed to open the packaging bag from the inside, so that the granules can enter the packaging bag smoothly. However, since the external support rods are fixed, if the external support structure forcibly opens a thin packaging bag or a material with poor elasticity, it will cause the bag to tear, ultimately causing the packaging bag to break.

[0004] In summary, to ensure packaging quality, it is necessary to address the issue of packaging bags being torn, and to ensure that the external support structure can adjust the range of expansion according to the size and material of the packaging bag. Utility Model Content

[0005] The present invention provides a pesticide granule packaging device, which aims to solve the following problem: because the external support rod is fixed, if the external support structure forcibly opens a thin packaging bag or a material with poor elasticity, the bag body will tear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pesticide granule packaging device, comprising a packaging frame, a top plate installed at the upper end of the packaging frame, a feeding square tube installed at the lower end of the top plate, four fixed frames symmetrically installed on the surface of the feeding square tube, a rotating shaft installed on the inner side of the fixed frames, multiple adjustment holes symmetrically opened on the surface of the fixed frames, an outer support plate installed on the outer side of the rotating shaft, a roller rotatably connected to the end of the outer support plate away from the rotating shaft, a pin rod slidably connected inside the adjustment hole, the pin rod being located below the outer support plate, a primary packaging mechanism provided on the packaging frame, and a complete packaging mechanism provided on the packaging frame.

[0007] In a preferred embodiment, the initial packaging mechanism is used to seal one side of the packaging bag. The initial packaging mechanism includes a bag-side heat sealing assembly and a bag feeding assembly. The bag-side heat sealing assembly is used to heat seal the side of the packaging bag, and the bag feeding assembly is used to convey the packaging strap downwards.

[0008] In a preferred embodiment, the bag-side heat sealing assembly includes an upper displacement frame mounted inside the sealing frame, an upper mounting plate mounted inside the upper displacement frame, a first motor mounted on the surface of the upper mounting plate, an upper lead screw mounted on the output end of the first motor, an upper slider mounted on the outside of the upper lead screw, an upper connecting rod mounted on the surface of the upper slider, and a bag-side heat sealing knife mounted on the end of the upper connecting rod away from the upper slider. The first motor is used to control the horizontal movement of the bag-side heat sealing knife.

[0009] In a preferred embodiment, the bag feeding assembly includes a lower hot press plate mounted inside the packaging frame, a feeding plate mounted on the upper end of the lower hot press plate, a second motor mounted on the surface of the feeding plate, a feeding drive wheel mounted on the output end of the second motor, and a feeding driven wheel mounted on the surface of the feeding plate. The second motor is used to control the rotational movement of the feeding drive wheel.

[0010] In a preferred embodiment, the full sealing mechanism is used to fully seal the packaging bag. The full sealing mechanism includes a bag opening heat sealing assembly and a positioning clamp assembly. The bag opening heat sealing assembly is used to heat seal the upper and lower ends of the packaging bag, and the positioning clamp assembly is used to cut the packaging bag.

[0011] In a preferred embodiment, the bag opening heat sealing assembly includes a lower displacement frame mounted on the surface of the lower hot platen, a lower mounting plate mounted inside the lower displacement frame, a third motor mounted on the surface of the lower mounting plate, a lower lead screw mounted on the output end of the third motor, a lower slider mounted on the outside of the lower lead screw, a lower connecting rod mounted on the surface of the lower slider, and a bag opening heat sealing knife mounted on the lower connecting rod at the end away from the lower slider. The third motor is used to control the horizontal movement of the bag opening heat sealing knife.

[0012] In a preferred embodiment, the positioning clamp assembly includes a movable clamp plate mounted on the upper end of the bag opening heat sealing knife and a fixed clamp plate mounted on the upper end of the lower heat pressing plate.

[0013] In a preferred embodiment, a packaging bag limiting clamp is installed at the lower end of the top plate, and an upper hot press plate is installed at the lower end of the top plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model features an adjustable opening design at the four corners of the packaging bag, which allows for flexible adjustment of the opening range according to the softness and thickness of the bag material. The external opening angle can be fixed by using pins to lock into the adjustment holes at different heights. The soft rubber rollers not only protect the bag from being torn but also make the material feeding smoother, thus effectively preventing the problem of thin bags being torn by force.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6 A pesticide granule packaging device includes a packaging frame 1, a top plate 11 installed at the upper end of the packaging frame 1, a feeding square tube 12 installed at the lower end of the top plate 11, four fixed frames 13 symmetrically installed on the surface of the feeding square tube 12, a rotating shaft 14 installed on the inner side of the fixed frame 13, a plurality of adjustment holes 15 symmetrically opened on the surface of the fixed frame 13, an outer support plate 16 installed on the outer side of the rotating shaft 14, a roller 17 rotatably connected to the end of the outer support plate 16 away from the rotating shaft 14, a pin rod 18 slidably connected inside the adjustment hole 15, the pin rod 18 being located below the outer support plate 16, a primary packaging mechanism and a complete packaging mechanism are provided on the packaging frame 1.

[0025] It should be noted that the adjustment holes 15 are evenly distributed, and their centers coincide with the axis of the rotating shaft 14. By inserting the pin rod 18 into the adjustment holes 15 at different heights, the rotation angle range of the outer support plate 16 can be limited, thereby adapting to packaging bags of different thicknesses or elasticities. The roller 17 adopts a silicone-coated design, which not only avoids scratching the bag body, but also reduces the resistance to opening through rolling friction.

[0026] It is worth noting that the four fixed frames 13 are arranged symmetrically to distribute the external support force evenly. The packaging bag limiting hoop 19 is used to limit the downward conveying position of the packaging bag and prevent it from shifting during the opening process.

[0027] Refer to the instruction manual appendix Figures 1 to 5 The primary sealing mechanism is used to seal one side of the packaging bag. The primary sealing mechanism includes a bag-side heat sealing assembly and a bag feeding assembly. The bag-side heat sealing assembly is used to heat seal the side of the packaging bag, and the bag feeding assembly is used to convey the packaging strap downwards.

[0028] It should be noted that single-side sealing refers to first heat-sealing one side of the packaging bag to form a cylindrical structure, and then gradually pulling down the unsealed side through the bag feeding component to fill the granules. This step-by-step sealing method can avoid the air trapped inside the bag due to simultaneous heat sealing.

[0029] Refer to the instruction manual appendix Figure 4 The bag-side heat sealing assembly includes an upper displacement frame 311 installed inside the sealing frame 1, an upper mounting plate 312 installed inside the upper displacement frame 311, a first motor 313 installed on the surface of the upper mounting plate 312, an upper lead screw 314 installed at the output end of the first motor 313, an upper slider 315 installed on the outside of the upper lead screw 314, an upper connecting rod 316 installed on the surface of the upper slider 315, and a bag-side heat sealing knife 317 installed on the upper connecting rod 316 away from the upper slider 315. The first motor 313 is used to control the horizontal movement of the bag-side heat sealing knife 317.

[0030] It should be noted that the upper lead screw 314, in conjunction with the stepping control of the first motor 313, can move the bag-side heat sealing knife 317 towards the upper heat pressure plate 20, thereby heat-sealing the side of the packaging bag through the cooperation of the bag-side heat sealing knife 317 and the upper heat pressure plate 20.

[0031] Refer to the instruction manual appendix Figure 5 The bag feeding assembly includes a lower hot press plate 321 installed inside the packaging frame 1, a feeding plate 322 installed on the upper end of the lower hot press plate 321, a second motor 323 installed on the surface of the feeding plate 322, a feeding drive wheel 324 installed on the output end of the second motor 323, and a feeding driven wheel 325 installed on the surface of the feeding plate 322. The second motor 323 is used to control the rotational movement of the feeding drive wheel 324.

[0032] It should be noted that the surface of the feeding drive wheel 324 is provided with anti-slip texture, and the gap between it and the feeding driven wheel 325 can accommodate the sealed edge of the heat-sealed packaging bag, allowing for secondary pressing of the sealed edge during the bag feeding process.

[0033] Refer to the instruction manual appendix Figures 5 to 6 The complete sealing mechanism is used to completely seal the packaging bag. The complete sealing mechanism includes a bag opening heat sealing assembly and a positioning clamp assembly. The bag opening heat sealing assembly is used to heat seal the top and bottom ends of the packaging bag, and the positioning clamp assembly is used to cut the packaging bag.

[0034] It should be noted that complete sealing involves two actions: heat sealing at the top and heat sealing at the bottom. While the top of the bag is being heat sealed, the bag is clamped by the positioning clamp assembly to form an isolation zone. This allows for the filling of the bag above while the top of a single bag is being heat sealed.

[0035] It is worth noting that the upper and lower heat seals are controlled by temperature difference, with the upper heat seal temperature being higher than the lower one, to prevent the granules from deteriorating due to heat.

[0036] Refer to the instruction manual appendix Figure 6 The bag opening heat sealing assembly includes a lower displacement frame 411 mounted on the surface of the lower heat press plate 321, a lower mounting plate 412 mounted inside the lower displacement frame 411, a third motor 413 mounted on the surface of the lower mounting plate 412, a lower lead screw 414 mounted on the output end of the third motor 413, a lower slider 415 mounted on the outside of the lower lead screw 414, a lower connecting rod 416 mounted on the surface of the lower slider 415, and a bag opening heat sealing knife 417 mounted on the lower connecting rod 416 away from the lower slider 415. The third motor 413 is used to control the horizontal movement of the bag opening heat sealing knife 417.

[0037] It should be noted that the third motor 413 drives the lower lead screw 414 to rotate, which in turn drives the bag opening heat sealing knife 417 to move towards the lower heat pressure plate 321 via the lower slider 415, until the bag opening heat sealing knife 417 cooperates with the lower heat pressure plate 321 to heat seal the packaging bag.

[0038] Refer to the instruction manual appendix Figure 5 The positioning clamp assembly includes a movable clamping plate 421 installed on the upper end of the bag opening heat sealing knife 417 and a fixed clamping plate 422 installed on the upper end of the lower heat pressing plate 321.

[0039] It should be noted that when the bag opening heat sealing knife 417 moves in the direction of the downward heat pressure plate 321, it simultaneously drives the movable clamping plate 421 to move towards the fixed clamping plate 422 until the movable clamping plate 421 and the fixed clamping plate 422 cooperate to clamp the packaging bag in a roughly manner, preventing the packaging bag from shifting position.

[0040] Refer to the instruction manual appendix Figure 2 A packaging bag limiting clamp 19 is installed at the lower end of the top plate 11, and an upper hot press plate 20 is installed at the lower end of the top plate 11.

[0041] It should be noted that by passing the packaging material through the packaging bag limiting clamp 19 and the feed square tube 12, the general shape of the packaging bag is restricted by the packaging bag limiting clamp 19, and the conveying range of the packaging bag is also restricted.

[0042] Working principle: The packaging bag is passed between the packaging bag limiting clamp 19 and the feeding square tube 12. By adjusting the insertion position of the pin rod 18 in the adjustment hole 15 at different heights, the outer support plate 16 rotates around the rotating shaft 14 to a suitable angle, driving the roller 17 to moderately open the packaging bag. The first motor 313 drives the upper lead screw 314 to rotate, driving the upper slider 315 and the upper connecting rod 316 to move, so that the bag side heat sealing knife 317 cooperates with the upper hot pressure plate 20 to complete the heat sealing of one side of the packaging bag. The second motor 323 drives the feeding drive wheel 324 to rotate, which cooperates with the feeding driven wheel 325 to convey the sealed packaging bag downwards, while performing secondary pressing. The granules enter the opened packaging bag through the feeding square tube 12. When the material is loaded to the set position, the third motor 413 drives the lower lead screw 414 to rotate, which in turn moves the lower slider 415 and the lower connecting rod 416, so that the bag opening heat sealing knife 417 cooperates with the lower heat pressure plate 321 to complete the lower end heat sealing. At the same time, the movable clamping plate 421 and the fixed clamping plate 422 clamp the bag body to form an isolation zone. Then the bag opening heat sealing knife 417 continues to move to complete the upper end heat sealing, forming a complete seal. Throughout the process, the packaging bag limiting hoop 19 keeps the bag body in a stable position. The symmetrical layout of the four outer support plates 16 ensures that the opening force is evenly distributed. The silicone coating design of the rollers 17 avoids scratching the bag body. Through the multi-level adjustment function of the adjustment hole 15, it can adapt to packaging bag materials of different thicknesses and elasticities, effectively preventing the bag body from tearing.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
