Description

Technical Field

[0001] This utility model relates to the field of instant powder packaging sealing technology, specifically an instant powder packaging nitrogen filling and sealing machine. Background Technology

[0002] Instant powder is a type of convenient product made from powder as its core form, through processes such as pretreatment, mixing, and pulverization. It can be consumed directly after being quickly dissolved or dispersed by brewing. Instant powder packaging nitrogen-filled sealing machine is an automated packaging equipment that integrates quantitative feeding, nitrogen replacement of air, and sealing functions for instant powder. Its core function is to prevent oxidation, moisture, and freshness, thereby extending the product's shelf life.

[0003] Existing instant powder packaging nitrogen-filled sealing machines are not suitable for buffer sealing. As the sealing machine is used, its sealing accuracy decreases, which can easily lead to damage to the packaging bags due to excessive sealing force.

[0004] Therefore, a nitrogen-filled and sealed powder packaging machine is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an instant powder packaging nitrogen filling and sealing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nitrogen-filling and sealing machine for instant powder packaging, comprising a frame, wherein an air extraction and nitrogen filling machine is provided on the outer wall of the frame, the air extraction and nitrogen filling machine being used to extract air and fill nitrogen into the instant powder packaging bag; A sealing unit is placed inside a frame and extends to the outside of the frame. The sealing unit includes a sealing component and a driving component. The sealing component is used to buffer and seal the instant powder packaging bag, and the driving component is used to drive the sealing component to seal the packaging bag. The auxiliary unit is used to position and transport the instant powder packaging bag to the inside of the sealing unit so that the sealing unit can seal the packaging bag. With the cooperation of the sealing unit and the vacuum nitrogen filling machine, the instant powder packaging bag can be filled with nitrogen and the sealing can be buffered. Under the restriction of the auxiliary unit, the instant powder packaging bag can be auxiliaryly transported to the inside of the sealing unit.

[0007] Preferably, the sealing assembly includes a push plate slidably disposed inside the frame, a first magnetic ring connected to the side wall of the push plate, a slide rod slidably connected inside the first magnetic ring, a second magnetic ring connected to the end of the slide rod, a pressure plate connected to the side wall of the second magnetic ring, and a sealing plate connected to the side of the pressure plate away from the second magnetic ring.

[0008] Preferably, the drive assembly includes a connecting plate hinged to the top surface of the push plate, a connecting block hinged to the end of the connecting plate away from the push plate, and a telescopic rod connected to the bottom of the connecting block.

[0009] Preferably, the first magnetic ring and the second magnetic ring are magnetically repulsive, and the first magnetic ring and the second magnetic ring are arranged in parallel. Under the restriction of magnetic repulsion, the instant powder packaging bag can be buffered and sealed by the pressure plate and the sealing plate.

[0010] Preferably, the bottom of the telescopic rod is connected to the top surface of the frame, and the connecting block is connected to the vacuum and nitrogen filling machine. Under the push of the telescopic rod, the connecting block can drive the mounting plate in the vacuum and nitrogen filling machine to move, so that the mounting plate drives the vacuum and filling pipe to move upward.

[0011] Preferably, the auxiliary unit includes a pull plate slidably disposed within the frame, a bearing plate connected to the end of the pull plate, a limit rod connected to the top surface of the bearing plate, and a spring sleeved on the outer wall of the limit rod; A connecting frame is connected to the top surface of the bearing plate, and a pair of clamping plates are hinged to the outer wall of the connecting frame.

[0012] Preferably, the clamping plates are set at a right angle at the end away from the connecting frame, and a counterweight is provided at the top of the clamping plates. Under the constraint of the right-angle clamping plates, the clamping plates can be prevented from rotating outward towards the bearing plate, so that the two clamping plates can deflect in opposite directions to assist in clamping the packaging bag.

[0013] Preferably, the outer wall of the limiting rod is slidably disposed within the frame, and the ends of the springs are respectively connected to the bottom of the frame and the top surface of the bearing plate. Under the elastic action of the springs, the bearing plate can be pushed to reset, and under the restriction of the limiting rods, the sliding of the bearing plate can be restricted.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, during sealing, the auxiliary unit places the packaging bag sealing device between two pressure plates, and the filling tube extends into the bag. The telescopic rod is activated to push the connecting block, which in turn drives the two push plates to slide in opposite directions. Under the repulsive force of the first and second magnetic rings and the guiding action of the sliding rod, the push plates drive the sealing plate to clamp the packaging bag. After the vacuuming and nitrogen filling machine completes vacuuming and nitrogen filling through the filling tube, the telescopic rod continues to push the connecting block, causing the filling tube to exit the bag. Simultaneously, the push plates, with the aid of magnetic repulsion, apply buffer pressure to the packaging bag using the sealing plate to complete the sealing. The filling tube uses a soft tube body, which does not affect the gas pumping function. 2. In this invention, during sealing, the packaging bag is placed on the top surface of the support plate, and the clamping plates are released. Due to the weight distribution at the top, the plates rotate in opposite directions to clamp the packaging bag. Pulling the pull plate moves the support plate and the packaging bag upwards, allowing the sealing point to enter between the two sealing plates. After sealing by the sealing unit, the pull plate is released, and the spring pushes the support plate back to its original position, allowing the packaging bag to be removed. This structure assists in conveying the packaging bag and prevents operators from being accidentally injured by the sealing plates while holding the sealing point. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a nitrogen-filling and sealing machine for instant powder packaging, including a frame 1. The outer wall of the frame 1 is provided with a vacuum nitrogen filling machine 2, which is used to vacuum and fill the instant powder packaging bag with nitrogen. Sealing unit 3 is located inside frame 1 and extends to the outside of frame 1. Sealing unit 3 includes sealing component and driving component. Sealing component is used to buffer and seal instant powder packaging bag. Driving component is used to drive sealing component to seal packaging bag. Auxiliary unit 4 is used to position and transport the instant powder packaging bag to the inside of the sealing unit 3 so that the sealing unit 3 can seal the packaging bag.

[0024] With the cooperation of sealing unit 3 and vacuum nitrogen filling machine 2, the instant powder packaging bag can be filled with nitrogen and sealed with buffer. Under the restriction of auxiliary unit 4, the instant powder packaging bag can be auxiliaryly conveyed to the inside of sealing unit 3.

[0025] Example 2 Reference Figure 3 and Figure 4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The sealing assembly includes a push plate 31 that is slidably disposed inside the frame 1. A first magnetic ring 32 is connected to the side wall of the push plate 31. A slide rod 33 is slidably connected inside the first magnetic ring 32. A second magnetic ring 34 is connected to the end of the slide rod 33. A pressure plate 35 is connected to the side wall of the second magnetic ring 34. A sealing plate 36 is connected to the side of the pressure plate 35 away from the second magnetic ring 34. The drive assembly includes a connecting plate 37 hinged to the top surface of the push plate 31. A connecting block 38 is hinged to the end of the connecting plate 37 away from the push plate 31. A telescopic rod 39 is connected to the bottom of the connecting block 38.

[0026] Among them, the first magnetic ring 32 and the second magnetic ring 34 are magnetically repulsive and are arranged in parallel. Under the restriction of magnetic repulsion, the instant powder packaging bag can be buffered and sealed by the pressure plate 35 and the sealing plate 36.

[0027] The telescopic rod 39 is connected to the top surface of the frame 1 at its bottom, and the connecting block 38 is connected to the vacuum and nitrogen filling machine 2. Under the push of the telescopic rod 39, the mounting plate in the vacuum and nitrogen filling machine 2 can be moved through the connecting block 38, so that the mounting plate can drive the vacuum and filling pipe to move upward.

[0028] When sealing the instant powder packaging bag, the auxiliary unit 4 places the sealing bag between two pressure plates 35. At this time, the suction and filling pipe of the vacuum and nitrogen filling machine 2 is placed inside the packaging bag. The telescopic rod 39 is activated, which pushes the connecting block 38 upward. The connecting block 38 pulls the push plate 31 through the connecting plate 37. The two push plates 31 slide against each other inside the frame 1. Due to the magnetic repulsion between the first magnetic ring 32 and the second magnetic ring 34, and the sliding rod 33 sliding inside the push plate 31, under its constraint, the push plate 31, in conjunction with the magnetic repulsion and the sliding rod 33, presses the pressure plate 35 and the sealing plate 3. 6. Pushing causes the two sealing plates 36 to contact and clamp with the outer wall of the packaging bag. At this time, the vacuuming and filling tube in the vacuuming and filling machine 2 vacuums the packaging bag and fills it with nitrogen. After the nitrogen filling is completed, the telescopic rod 39 continues to push the connecting block 38. The connecting block 38 drives the mounting plate on the outer wall of the vacuuming and filling tube to move upward, and the vacuuming and filling tube is no longer placed inside the packaging bag. The upward connecting block 38 causes the two push plates 31 to slide on the outer wall of the slide rod 33. With the magnetic repulsion and sealing plate 36, sealing pressure can be applied to the packaging bag to seal it. Under the restriction of magnetic repulsion, the packaging bag can be sealed with buffer. When the two push plates 31 drive the two sealing plates 36 to move in opposite directions, the structure causes the sealing plates 36 to initially contact the outer wall of the packaging bag and press against the filling tube inside the packaging bag. At this time, the vacuum-filling nitrogen machine 2 can evacuate air from the packaging bag and fill it with nitrogen. After the nitrogen filling is completed, the push plates 31 apply pressure to the sealing plates 36 through magnetic repulsion. At this time, the telescopic rod 39 drives the filling tube in the vacuum-filling nitrogen machine 2 to move upward through the connecting block 38, so that the filling tube is no longer placed inside the packaging bag, and the sealing plate 36 can then buffer and seal the packaging bag. Since the filling tube in the vacuum-filling nitrogen machine 2 is a soft tube, under its constraint, when the connecting block 38 drives the filling tube mounting plate to move up and down, it does not affect the pump body in the vacuum-filling nitrogen machine 2 to pump air into the filling tube.

[0029] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The auxiliary unit 4 includes a pull plate 41 that is slidably disposed in the frame 1. A bearing plate 42 is connected to the end of the pull plate 41. A limit rod 43 is connected to the top surface of the bearing plate 42. A spring 44 is sleeved on the outer wall of the limit rod 43. A connecting frame 45 is connected to the top surface of the bearing plate 42, and a pair of clamping plates 46 are hinged to the outer wall of the connecting frame 45.

[0030] The clamping plate 46 is set at a right angle at the end away from the connecting frame 45. The top of the clamping plate 46 is equipped with a counterweight. Under the restriction of the right-angle clamping plate 46, the clamping plate 46 can be prevented from rotating outward from the bearing plate 42, so that the two clamping plates 46 can deflect in opposite directions to assist in clamping the packaging bag.

[0031] The limiting rod 43 is slidably disposed on the outer wall of the frame 1, and the ends of the spring 44 are respectively connected to the bottom of the frame 1 and the top surface of the bearing plate 42. Under the elastic action of the spring 44, the bearing plate 42 can be reset and pushed, and under the restriction of the limiting rod 43, the sliding of the bearing plate 42 can be restricted.

[0032] When sealing the instant powder packaging bag, place it on the top surface of the support plate 42, and release the clamping plates 46. Due to the weight at the top of the clamping plates 46, they rotate in opposite directions to assist in clamping the packaging bag. Pull the pull plate 41, causing it to move the support plate 42 and the packaging bag upwards, placing the packaging bag between the two sealing plates 36. The sealing unit 3 then seals the packaging bag. After sealing, release the pull plate 41. Under the elastic action of the spring 44, the support plate 42 is pushed downwards to reset, causing the limiting rod 43 to slide within the frame 1, allowing the instant powder to be removed. This structure assists in conveying the instant powder packaging bag during sealing, preventing the operator from holding the sealing point and getting caught in the sealing plates 36.

[0033] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
