Description

Technical Field

[0001] This utility model relates to the technical field of vermicelli processing equipment, and in particular to a vermicelli packaging device. Background Technology

[0002] As is widely known, automated packaging equipment for irregularly shaped foods such as vermicelli and rice noodles generally uses heat sealing to seal the filled packaging bags.

[0003] Chinese patent CN214824423U describes an automatic packaging device for ready-to-eat rice noodles, comprising a mounting base, a right platform, and a left platform. A box is welded onto the right platform, and a rotary heat cutter is installed inside the box. However, in actual use, the following problems still exist:

[0004] During the filling process, the irregular accumulation of strip-shaped materials inside the bag creates uneven support and compression on the bag wall, which can easily lead to wrinkles or local overlap at the bag opening. Traditional heat sealing devices often have rigid integral structures for their heat sealing blades, which cannot adapt to the unevenness of the bag opening caused by the contents. This can result in burn-through at areas of concentrated pressure or leaks at areas of insufficient pressure, affecting the sealing success rate.

[0005] Therefore, a repackaging device for fans is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a packaging device for vermicelli.

[0007] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0008] A rice noodle packaging device includes a conveying assembly, a heat-sealing machine body, a guide hopper, a first pressure plate, and a second pressure plate. The conveying assembly is connected to the outer shell of the heat-sealing machine body via a fixing member. The guide hopper is located below the conveying assembly and connected to the heat-sealing machine body. The first pressure plate and the second pressure plate are respectively located on both sides of the outlet of the guide hopper and slidably connected to the heat-sealing machine body. A bag-mouth leveling and pressure-equalizing heat-sealing component is provided between the first pressure plate and the second pressure plate. The bag-mouth leveling and pressure-equalizing heat-sealing component includes a first push rod, a second push rod, a heat-sealing knife, a uniform pressure application component, and a bag-mouth leveling component. One end of the first push rod is fixedly connected to the side of the first pressure plate, and the other end of the first push rod is connected to the fixed end of the uniform pressure application component. The movable end of the uniform pressure application component is connected to the heat-sealing knife. One end of the second push rod is connected to the side of the second pressure plate, and the other end of the second push rod is connected to the fixed end of the bag-mouth leveling component.

[0009] The uniform pressure application assembly includes a pressure block and a pressure equalizing component. The pressure block has a pressure chamber. The first push rod is fixedly connected to the side of the pressure block adjacent to the first pressure plate. The side of the pressure block away from the first pressure plate is connected to the fixed end of the pressure equalizing component. The movable end of the pressure equalizing component is connected to the heat sealing knife.

[0010] The pressure equalizing component is provided in a plurality of parts, which are evenly distributed on the pressure block. Each pressure equalizing component includes a pressure tube and a rod-shaped piston. One end of the pressure tube is connected to the side of the pressure block and is connected to the pressure chamber. One end of the rod-shaped piston is slidably connected to the inner wall of the pressure tube and located inside the pressure tube. The other end of the rod-shaped piston is fixedly connected to the heat sealing knife.

[0011] The bag opening leveling assembly includes an auxiliary heat-sealing block and a bag opening leveling component. The side of the auxiliary heat-sealing block adjacent to the second pressure plate is fixedly connected to the second push rod, and the side of the auxiliary heat-sealing block away from the second push rod is connected to the fixed end of the bag opening leveling component.

[0012] Two bag opening leveling components are provided, and the two bag opening leveling components are symmetrically distributed on the auxiliary heat sealing block. Each bag opening leveling component includes a trapezoidal slider and a spring. The auxiliary heat sealing block has a sliding groove on its side away from the second push rod. The sliding groove is inclinedly disposed in the auxiliary heat sealing block. One end of the trapezoidal slider is located in the sliding groove and is slidably connected to the inner wall of the sliding groove. The other end of the trapezoidal slider located in the sliding groove is connected to the inner wall of the sliding groove away from the trapezoidal slider through the spring located in the sliding groove.

[0013] The spring is provided in at least two parts, and the at least two springs are evenly distributed in the sliding groove.

[0014] The trapezoidal slider has several rolling grooves on its side away from the second push rod, and a smoothing wheel is provided in the rolling groove. The smoothing wheel is rotatably connected to the trapezoidal slider.

[0015] Compared with the prior art, this utility model has the following beneficial effects: By setting an inclined sliding groove and a bag opening leveling component linked with a trapezoidal slider, the uneven pressure caused by wrinkles or partial overlap of the packaging bag due to the support of the vermicelli is avoided. This not only improves the initial flatness of the heat-sealing area, but also ensures the uniformity of pressure on the heat-sealing line, thereby preventing leaks or burn-through. By setting a sealed pressure chamber in the pressure block and connecting multiple rod-shaped pistons, leaks or burn-through caused by uneven local heat-sealing pressure at the bag opening are avoided, further improving the uniformity and consistency of pressure on the heat-sealing line, and preventing leaks or burn-through.

[0025] like Figures 1-4As shown, a rice noodle packaging device includes a conveying assembly 1, a heat sealing machine body 2, a guide hopper 3, a first pressure plate 4, and a second pressure plate 5. The conveying assembly 1 is connected to the outer shell of the heat sealing machine body 2 via a fixing member. The guide hopper 3 is located below the conveying assembly 1 and connected to the heat sealing machine body 2. The first pressure plate 4 and the second pressure plate 5 are respectively located on both sides of the outlet of the guide hopper 3 and are slidably connected to the heat sealing machine body 2. A bag-opening leveling and pressure-equalizing heat sealing section is provided between the first pressure plate 4 and the second pressure plate 5. Component 19, the bag opening leveling and pressure equalizing heat sealing component 19 includes a first push rod 6, a second push rod 7, a heat sealing knife 8, a uniform pressure application component and a bag opening leveling component. One end of the first push rod 6 is fixedly connected to the side of the first pressure plate 4, and the other end of the first push rod 6 is connected to the fixed end of the uniform pressure application component. The movable end of the uniform pressure application component is connected to the heat sealing knife 8. One end of the second push rod 7 is connected to the side of the second pressure plate 5, and the other end of the second push rod 7 is connected to the fixed end of the bag opening leveling component.

[0026] like Figures 2-3 As shown, the uniform pressure application assembly includes a pressure block 9 and a pressure equalizing component. The pressure block 9 has a pressure chamber 10. The first push rod 6 is fixedly connected to the side of the pressure block 9 adjacent to the first pressure plate 4. The side of the pressure block 9 away from the first pressure plate 4 is connected to the fixed end of the pressure equalizing component. The movable end of the pressure equalizing component is connected to the heat sealing knife 8.

[0027] like Figures 2-3 As shown, there are several pressure equalization components, which are evenly distributed on the pressure block 9. Each pressure equalization component includes a pressure tube 11 and a rod-shaped piston 12. One end of the pressure tube 11 is connected to the side of the pressure block 9 and is connected to the pressure chamber 10. One end of the rod-shaped piston 12 is slidably connected to the inner wall of the pressure tube 11, and the other end of the rod-shaped piston 12 is fixedly connected to the heat sealing knife 8.

[0028] like Figure 2 , Figure 3 and Figure 6 As shown, the bag opening leveling assembly includes an auxiliary heat sealing block 13 and a bag opening leveling component. The side of the auxiliary heat sealing block 13 adjacent to the second pressure plate 5 is fixedly connected to the second push rod 7, and the side of the auxiliary heat sealing block 13 away from the second push rod 7 is connected to the fixed end of the bag opening leveling component.

[0029] like Figure 2 , Figure 3 and Figure 6As shown, there are two bag opening leveling components, which are symmetrically distributed on the auxiliary heat sealing block 13. Each bag opening leveling component includes a trapezoidal slider 14 and a spring 15. The auxiliary heat sealing block 13 has a sliding groove 16 on its side away from the second push rod 7. The sliding groove 16 is inclinedly disposed in the auxiliary heat sealing block 13. One end of the trapezoidal slider 14 is located in the sliding groove 16 and is slidably connected to the inner wall of the sliding groove 16. The end of the trapezoidal slider 14 located in the sliding groove 16 is connected to the inner wall of the sliding groove 16 away from the trapezoidal slider 14 through the spring 15 located in the sliding groove 16.

[0030] like Figure 6 As shown, at least two springs 15 are provided, and at least two springs 15 are evenly distributed in the sliding groove 16.

[0031] like Figures 5-6 As shown, the trapezoidal slider 14 has several rolling grooves 17 on its side away from the second push rod 7, and a smoothing wheel 18 is provided in the rolling groove 17. The smoothing wheel 18 is rotatably connected to the trapezoidal slider 14.

[0032] The work process is as follows:

[0033] S1, during use, the conveying assembly 1 and the heat sealing machine body 2 are started. The conveying assembly 1 feeds the rice noodles into the guide hopper 3, where they fall into an unsealed packaging bag. Subsequently, the heat sealing machine body 2 drives the first pressure plate 4 and the second pressure plate 5 to move towards each other, clamping the bag opening at the outlet of the guide hopper 3. The movement of the first pressure plate 4 pushes the uniform pressure assembly and the heat sealing knife 8 towards the bag opening via the first push rod 6. At the same time, the movement of the second pressure plate 5 pushes the auxiliary heat sealing block 13 towards the bag opening via the second push rod 7. As the auxiliary heat sealing block 13 moves forward, the two bag opening leveling components fixed on the auxiliary heat sealing block 13 connect... When the packaging bag is touched, the trapezoidal slider 14 of each bag opening leveling component slides inward under the constraint of the inclined sliding groove 16. This causes the trapezoidal slider 14 to slide radially to both sides as it approaches the bag opening. The smoothing wheel 18 on the trapezoidal slider 14 then radially stretches the plastic bag opening, smoothing out the wrinkles and providing a flat contact surface for subsequent heat sealing. By setting the bag opening leveling component that is linked to the inclined sliding groove 16 and the trapezoidal slider 14, the uneven pressure caused by wrinkles or partial overlap of the packaging bag due to the support of the fan is avoided. This not only improves the initial flatness of the heat sealing area but also ensures the uniformity of pressure on the heat sealing line, thereby preventing leaks or burn-through.

[0034] S2, During the heat sealing process, after the heat sealing knife 8 contacts the opening of the packaging bag, it pushes the rod-shaped piston 12 to slide inward along the pressure tube 11. The fluid in the sealed pressure chamber 10 inside the pressure block 9 transmits the pressure evenly to each rod-shaped piston 12, so that the pressure applied by each rod-shaped piston 12 to the heat sealing knife 8 is consistent, thereby ensuring that the entire heat sealing line is subjected to uniform force and achieving synchronous sealing. By setting a sealed pressure chamber 10 inside the pressure block 9 and connecting multiple rod-shaped pistons 12, leakage or burn-through caused by uneven local heat sealing pressure at the bag opening is avoided, further improving the uniformity and consistency of pressure on the heat sealing line and preventing leakage or burn-through.

[0035] In addition, to ensure smooth radial flattening of the bag opening and prevent scratching of the film, a rolling groove 17 is provided on the trapezoidal slider 14, and a rotatable smoothing wheel 18 is installed in the rolling groove 17 to change sliding friction into rolling friction. At the same time, to prevent the trapezoidal slider 14 from getting stuck or deviating in the sliding groove 16, at least two springs 15 are provided and the springs 15 are evenly distributed to provide balanced buffering and restoring force.

Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model.
