Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a vacuum packaging machine for agricultural products. Background Technology

[0002] Currently, the demand for agricultural products is enormous. However, due to different environments in different places, the agricultural products that can be grown are also different, so long-distance transportation is required. This makes the preservation of agricultural products particularly important. Nowadays, vacuum packaging machines are mostly used to achieve the preservation effect by vacuum packaging agricultural products.

[0003] For example, patent document CN210000648U discloses a vacuum packaging machine for agricultural products, including a vacuum machine body, a vacuum chamber, and a vacuum cover. The vacuum cover is hinged to the vacuum machine body, the vacuum chamber is opened on the upper surface of the vacuum machine body, the vacuum cover is closed on the vacuum chamber, a vacuum extraction hole is opened on the inner wall of the vacuum chamber, a fixing block is fixed in the vacuum chamber, a fixing groove is opened on the fixing block, a heating block is in the fixing groove, and limit devices are fixed at both ends of the fixing block. The limit devices include a fixing shell, an elastic element, a connecting element, and a clamping device. The fixing shell is fixed on the fixing block.

[0004] In actual use, the vacuum packaging machine proposed in the above patent documents only uses clamps to hold and fix the sealing of the packaging bag. However, the contact area between the clamps and the packaging bag is too small, resulting in insufficient stability in limiting the sealing of the packaging bag. This can easily cause unevenness at the sealing of the packaging bag, affecting the quality of vacuum packaging. Utility Model Content

[0005] This utility model discloses a vacuum packaging machine for agricultural products, which aims to solve the technical problems existing in packaging equipment in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vacuum packaging machine for agricultural products includes a vacuum box, a packaging sealing mechanism fixedly disposed on the upper surface of the vacuum box, and a support component disposed inside the vacuum box for supporting and limiting the packaging bag of agricultural products.

[0008] The packaging sealing mechanism includes a limiting box fixedly connected to the upper surface of the vacuum box. A sealing cover is rotatably connected to the upper surface of the limiting box. A strip-shaped limiting hole is opened on the upper surface of the vacuum box. The position of the strip-shaped limiting hole corresponds to the limiting box. An electric telescopic rod is fixedly installed on the left side of the limiting box. The telescopic end of the electric telescopic rod extends into the interior of the limiting box and is fixedly connected to a limiting clamp. Several strip-shaped push blocks are fixedly connected to the side of the limiting clamp.

[0009] By installing a packaging sealing mechanism at the top of the vacuum chamber, the opening of the agricultural product packaging bag can be fixed and limited, thereby improving the stability of the packaging bag inside the vacuum chamber.

[0010] The support assembly includes a lifting base plate, and a dual-axis motor is fixedly installed on the lower surface of the vacuum chamber. The dual-axis motor is used to adjust and position the height of the lifting base plate.

[0011] By installing a lifting base plate inside the vacuum chamber, a dual-axis motor can be used to drive the lifting base plate to move up and down inside the vacuum chamber. The lifting base plate can then be used to limit and support the bottom of the packaging bag, making it convenient to perform vacuuming operations on agricultural product packaging bags of different sizes.

[0012] In a preferred embodiment, a transmission shell is fixedly connected to both the left and right sides of the vacuum chamber, and a lifting screw is rotatably connected to the inner wall of the transmission shell. A connecting block is threaded onto the surface of the lifting screw, and one side of the connecting block extends into the interior of the vacuum chamber.

[0013] In a preferred embodiment, rectangular guide holes are provided on the left and right inner walls of the vacuum chamber, the connecting block is slidably connected to the inner wall of the rectangular guide hole, and the two sides of the lifting base plate are fixedly connected to the surfaces of the two connecting blocks respectively.

[0014] In a preferred embodiment, a driven gear is fixedly connected to the surface of the lifting screw, and a transmission rod is fixedly connected to each of the two output ends of the dual-axis motor. The end of the transmission rod extends into the interior of the transmission housing and is fixedly connected to a drive gear, which meshes with the driven gear.

[0015] By setting up a transmission rod, a drive gear, and a driven gear, a dual-axis motor can be used to drive two lifting screws to rotate simultaneously.

[0016] In a preferred embodiment, a support back plate is fixedly connected to the inner wall of the limiting box, and the position of the support back plate corresponds to that of the limiting clamp.

[0017] By setting a support backplate, the sealing point of the packaging bag can be limited and supported, so that the limiting clamps squeeze the packaging bag onto the surface of the support backplate.

[0018] In a preferred embodiment, a heat-sealing frame is fixedly connected to the right side of the limiting box, a heat-sealing plate is provided inside the heat-sealing frame, and two pneumatic push rods are fixedly provided on the right side of the heat-sealing frame.

[0019] By setting up a heat-sealing frame, after vacuuming is completed, the sealing opening of the packaging bag can be inserted into the heat-sealing frame, and then the pneumatic push rod can be used to drive the heat-sealing plate to perform heat sealing operation on the packaging bag.

[0020] In a preferred embodiment, a pump housing is fixedly installed on the back of the vacuum chamber, and a vacuum pump is installed inside the pump housing. The pumping end of the vacuum pump extends into the interior of the vacuum chamber, and an exhaust pipe is fixedly connected to the exhaust end of the vacuum pump. The output end of the exhaust pipe extends to the outside of the pump housing.

[0021] By setting up a vacuum pump, the air inside the vacuum chamber can be drawn in from the packaging bag and then expelled from the vacuum chamber to the outside.

[0022] As can be seen from the above, the vacuum packaging machine for agricultural products provided by this utility model has the following technical effects.

[0023] Firstly, by setting a packaging sealing mechanism on the top of the vacuum chamber, the opening of the agricultural product packaging bag can be fixed and limited, thus keeping the sealed end of the packaging bag flat. This allows the air in the packaging bag to be discharged into the vacuum chamber. By setting a heat sealing frame on the side of the limiting box, after the air inside the packaging bag is evacuated, the heat sealing plate is used to heat and seal the sealed end of the packaging bag, achieving the purpose of convenient sealing operation.

[0024] Secondly, by installing a lifting base plate inside the vacuum chamber, a dual-axis motor can drive two lifting screws to rotate, thereby moving the lifting base plate up and down inside the vacuum chamber. The lifting base plate then limits and supports the bottom of the packaging bag, facilitating vacuuming operations for agricultural product packaging bags of different sizes and improving the stability of the packaging bags inside the vacuum chamber.

[0032] 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.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Reference Figure 1 and Figure 2 A vacuum packaging machine for agricultural products includes a vacuum box 1, a packaging sealing mechanism 2 fixedly installed on the upper surface of the vacuum box 1, and a support component 3 installed inside the vacuum box 1 for supporting and limiting the packaging bag of agricultural products.

[0035] It should be noted that a pump box 8 is fixedly installed on the back of the vacuum box 1, and a vacuum pump 9 is installed inside the pump box 8. The pumping end of the vacuum pump 9 extends into the interior of the vacuum box 1, and the exhaust end of the vacuum pump 9 is fixedly connected to an exhaust pipe 10. The output end of the exhaust pipe 10 extends to the outside of the pump box 8.

[0036] In a preferred embodiment, the packaging sealing mechanism 2 includes a limiting box 201 fixedly connected to the upper surface of the vacuum chamber 1. A sealing cover plate 202 is rotatably connected to the upper surface of the limiting box 201. A strip-shaped limiting hole 4 is opened on the upper surface of the vacuum chamber 1. The position of the strip-shaped limiting hole 4 corresponds to the limiting box 201. An electric telescopic rod 203 is fixedly installed on the left side of the limiting box 201. The telescopic end of the electric telescopic rod 203 extends into the interior of the limiting box 201 and is fixedly connected to a limiting clamping plate 204. Several strip-shaped push blocks 205 are fixedly connected to the side of the limiting clamping plate 204.

[0037] It should be noted that a support back plate 206 is fixedly connected to the inner wall of the limiting box 201, and the position of the support back plate 206 corresponds to that of the limiting clamp 204.

[0038] Through the above technical solution, when the limiting clamp 204 clamps the packaging bag, the strip push block 205 can be used to press the packaging bag against the surface of the support back plate 206. This not only clamps and fixes the packaging bag, but also allows the air venting operation of the packaging bag to be performed by utilizing the gap between two adjacent strip push blocks 205. This achieves the goal of clamping and limiting the packaging bag without affecting the air venting operation.

[0039] Reference Figure 3 and Figure 4 In a preferred embodiment, a heat-sealing frame 5 is fixedly connected to the right side of the limiting box 201, a heat-sealing plate 6 is provided inside the heat-sealing frame 5, and two pneumatic push rods 7 are fixedly provided on the right side of the heat-sealing frame 5.

[0040] It is worth noting that by setting a packaging sealing mechanism 2 on the top of the vacuum chamber 1, the opening of the agricultural product packaging bag can be fixed and limited by the packaging sealing mechanism 2, so that the sealed part of the packaging bag remains flat, and the air in the packaging bag can be discharged into the vacuum chamber 1. By setting a heat sealing frame 5 on the side of the limiting box 201, after the air inside the packaging bag is evacuated, the heat sealing plate 6 is used to heat and seal the sealed part of the packaging bag, so as to facilitate the sealing operation.

[0041] In a preferred embodiment, the support assembly 3 includes a lifting base plate 301, and a dual-axis motor 302 is fixedly installed on the lower surface of the vacuum box 1. The dual-axis motor 302 is used to adjust and position the height of the lifting base plate 301.

[0042] It should be noted that a transmission shell 303 is fixedly connected to both the left and right sides of the vacuum chamber 1. A lifting screw 304 is rotatably connected to the inner wall of the transmission shell 303. A connecting block 305 is threadedly connected to the surface of the lifting screw 304. One side of the connecting block 305 extends into the interior of the vacuum chamber 1.

[0043] It should be noted that rectangular guide holes 306 are provided on the left and right inner walls of the vacuum chamber 1. The connecting block 305 is slidably connected to the inner wall of the rectangular guide hole 306, and the two sides of the lifting base plate 301 are fixedly connected to the surfaces of the two connecting blocks 305 respectively.

[0044] It should be noted that a driven gear 307 is fixedly connected to the surface of the lifting screw 304, and a transmission rod 308 is fixedly connected to both output ends of the dual-axis motor 302. The end of the transmission rod 308 extends into the interior of the transmission housing 303 and is fixedly connected to a drive gear 309, which meshes with the driven gear 307.

[0045] It is worth noting that by setting a lifting base plate 301 inside the vacuum chamber 1, after the agricultural product packaging bag is placed inside the vacuum chamber 1, the dual-axis motor 302 can drive the two transmission rods 308 to rotate, which in turn drives the two drive gears 309 to rotate, and at the same time drives the driven gear 307 and the lifting screw 304 to rotate, thereby causing the lifting base plate 301 to move up and down inside the vacuum chamber 1. The lifting base plate 301 is used to limit and support the bottom of the packaging bag, so that the top seal of the packaging bag can enter the strip-shaped limiting hole 4, which facilitates the vacuuming operation of agricultural product packaging bags of different sizes and improves the stability of the packaging bag inside the vacuum chamber 1.

[0046] Working principle: In use, first, place the packaging bag containing agricultural products onto the surface of the lifting base plate 301 inside the vacuum chamber 1. Then, start the dual-axis motor 302 to drive the lifting screw 304 to rotate, thereby driving the connecting block 305 to move upward inside the transmission housing 303, which in turn drives the lifting base plate 301 to move upward. The lifting base plate 301 drives the packaging bag to move upward, so that the top seal of the packaging bag can enter the limiting box 201. Then, the electric telescopic rod 203 drives the limiting clamp 204 to clamp and limit the seal of the packaging bag, and several strip push blocks 205 are used to press and limit the packaging bag. Then, start the vacuum pump 9 to perform a vacuuming operation on the vacuum chamber 1, thereby removing the air inside the packaging bag. After the vacuuming is completed, open the sealing cover 202 on the top of the limiting box 201, insert the seal of the packaging bag into the heat sealing frame 5, and then use the pneumatic push rod 7 to drive the heat sealing plate 6 to seal the packaging bag.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
