Detailed Implementation

[0016] Example

[0017] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail.

[0018] Automatic sealing devices, such as Figure 1As shown, the main body is a machine frame 10, with casters 12 at the bottom for easy movement. The casters 12 have a fixing mechanism for temporary fixation during operation. The machine frame 10 is equipped with several large modules: a bag-shrinking mechanism 20, a bag-opening mechanism 40, and a side-sealing mechanism 60. Each large module is equipped with a dedicated small module to work together to perform necessary actions. A control console 11 is located at the rear of the machine frame 10's platform. The control console 11 is electrically connected to the bag-shrinking mechanism 20, bag-clamping mechanism 30, bag-opening mechanism 40, atomizing mechanism 50, side-sealing mechanism 60, and bag-sealing mechanism 70. Through programming on the control console 11, the bag-shrinking mechanism 20, bag-clamping mechanism 30, bag-opening mechanism 40, atomizing mechanism 50, side-sealing mechanism 60, and bag-sealing mechanism 70 can operate automatically, while also retaining a manual operation interface for special actions. The bag-shrinking mechanism 20 is located at the front of the machine frame 10's platform. The bag-shrinking mechanism 20 includes two relatively sliding and symmetrically arranged bag-clamping mechanisms 30. The bag clamping mechanism 30 can be adjusted to the width of the product packaging bag to achieve the optimal gripping posture. Unlike the left-side bag clamping mechanism 30, the right-side bag clamping mechanism 30 is additionally equipped with a bag opening support mechanism 40. The bag opening support mechanism 40 primarily works in conjunction with the vertically lifting atomizing mechanism 50. The bag opening support mechanism 40 opens the opening of the product packaging bag, allowing the atomizing mechanism 50 to extend into the bag and spray water mist to wet it. The atomizing mechanism 50 is positioned between the two bag clamping mechanisms 30 to ensure the most even and reasonable distribution of the atomization area and degree. The side sealing mechanism 60 is located on the right side of the machine frame 10, opposite the bag clamping mechanism 30, and performs the sealing action after atomization is complete. The side sealing mechanism 60 includes two relatively sliding and longitudinally symmetrical sealing mechanisms 70, allowing for easy adjustment to the most suitable position according to the product packaging bag before sealing. The bag clamping mechanism 30 grips and releases the product bag opening, the bag shrinking mechanism 20 straightens the product bag opening, the atomizing mechanism 50 atomizes and adds liquid to the inside of the product, and the bag sealing mechanism 70 seals the bag opening.

[0019] like Figure 4As shown, the bag-shrinking mechanism 20 mainly includes a main plate 21, a rear plate 22, two belt assemblies 23, two bag-shrinking motors 24, a main slide rail 25, a reinforcing slide rail 26, two reinforcing sliders 27, and two connecting blocks 28. The main plate 21 is fixed on the raised base of the machine frame 10. Generally, a modular connecting frame is used to raise the plate according to the required height of the product packaging bag to avoid collision with the machine frame 10 or other components, which would affect the sealing progress. The rear plate 22 is vertically fixed at the rear end of the main plate 21. A rotating belt assembly 23 is provided on the front. The belt assembly 23 includes two drive wheels. One drive wheel connects to the output unit, and the other drive wheel cooperates. The belt sleeve is wrapped around the two drive wheels. The bag-shrinking motor 24 that drives the belt assembly 23 is provided on the back. The main slide rail 25 is located at the front end of the main plate 21. The main plate 21 also has a set of belt assemblies 23 with bag-shrinking motors 24, which are located between the rear plate 22 and the main slide rail 25. Two belt assemblies 23 are respectively connected to two bag clamping mechanisms 30, driving them to slide independently. The two bag clamping mechanisms 30 are slidably connected to the main slide rail 25, and the two sets of belt assemblies 23 pass through and drive the corresponding bag clamping mechanisms 30 to slide. A reinforcing slide rail 26 is also provided on the rear plate 22. The reinforcing slide rail 26 is located above the belt assemblies 23 on the rear plate 22 to avoid mutual interference. The reinforcing slide rail 26 is provided with two relatively sliding and symmetrically arranged reinforcing sliders 27. Each bag clamping mechanism 30 is connected to the reinforcing sliders 27 on each side through connecting blocks 28. The reinforcing sliders 27 slide along the reinforcing slide rail 26 as the corresponding bag clamping mechanism 30 slides, which not only cooperates with the movement of the bag clamping mechanism 30, but also enhances the stability in this process and improves the precision control. The bag clamping mechanism 30 mainly includes two sliding connecting frames 31, two forward extension rods 32, two clamping jaws 33, and two clamping cylinders 34. The sliding connecting frames 31 are slidably connected to both the main slide rail 25 and the reinforcing slide rail 26. The forward extension rod 32 is fixedly mounted on the sliding connecting frame 31. A clamp cylinder 34 with a clamping slot 33 is located at the end of the forward extension rod 32. The clamp cylinder 34 exerts force to open or close the clamping slot 33, thereby releasing or gripping the product packaging bag.

[0020] like Figure 2 As shown, the bag opening mechanism 40 mainly includes a lifting guide rail 41, a lifting frame 42, a lifting cylinder 43, and a front probe frame 44, and is equipped with an atomizing mechanism 50. The movable end of the lifting frame 42 connects to the right-side bag clamping mechanism 30. The lifting guide rail 41 is optimally positioned on the fixed end of the lifting frame 42, and the fixed end of the lifting frame 42 is fixedly mounted on the corresponding frame body. The lifting cylinder 43 connects to the movable end of the lifting frame 42. The front probe frame 44 connects to the front side of the movable end of the lifting frame 42. The atomizing mechanism 50 passes through the front end of the front probe frame 44. The lifting cylinder 43 drives the atomizing mechanism 50 on the front probe frame 44 to move freely up and down through the lifting frame 42, completing the action of extending into and out of the product packaging bag.

[0021] like Figure 3As shown, the side sealing mechanism 60 mainly includes a side plate 61, a guide rail assembly 62, and a slider assembly 63, and is equipped with a dedicated sealing mechanism 70. The side plate 61 is located on the right side of the machine frame 10. The guide rail assembly 62 is distributed parallel to the front of the side plate 61 and includes multiple parallel slide rails. The slider assembly 63 is slidably connected to the guide rail assembly 62 at corresponding positions, and each slide rail has at least two sliders. The sealing mechanism 70 is connected to the slider assembly 63, and the motor drives the slider assembly 63 to drive the sealing mechanism 70 to slide longitudinally along the guide rail assembly 62. The sealing mechanism 70 includes a sealing strip 71 and a sealing cylinder 72, an exhaust plate 73, and an exhaust cylinder 74 that cooperate with the sealing action to allow air to enter and exit. The two sealing strips 71 slide relative to each other and are symmetrically arranged in front and behind the upper slider assembly 63. Each sealing strip 71 is individually equipped with a sealing cylinder 72, and they work together to complete the basic heat sealing action. Two exhaust plates 73 slide relative to each other and are symmetrically arranged on the lower slider group 63, sliding synchronously with the corresponding sealing strip 71 to meet the exhaust requirements of hot air. An exhaust cylinder 74 is located on the side plate 61, connecting the sealing strip 71 and the exhaust plates 73.

[0022] After the product packaging bag is adjusted to the appropriate position by the two clamps 33, it is clamped. The atomizing mechanism 50 descends, opens, and extends into the product packaging bag to atomize, meeting the process requirements for the product to absorb moisture. The more uniform and freely diffused atomized liquid optimizes the product's absorption of moisture, resulting in higher process quality. After atomization, it leaves the product packaging bag and retracts from its position to make room. Driven by the bag clamping mechanism 30, the product packaging bag moves to the right and enters the range of motion of the sealing strip 71. The sealing strip 71 moves closer to the sealing area to perform heat sealing. The product packaging bag returns to its initial position, and the sealed product is removed.

[0023] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
