Description

Technical Field

[0001] This utility model relates to the field of bubble bag sealing technology, specifically to a bubble bag sealing device. Background Technology

[0002] Bubble bag sealing equipment is a device used to seal inflatable cushioning packaging materials. It uses heat sealing to firmly seal the opening of the air-filled bubble wrap bag, thereby ensuring that the contents are safely wrapped in the air cushioning system to achieve the purpose of shockproof, moisture-proof, and dustproof protection.

[0003] Bubble bag sealing equipment can be divided into cold-press sealing machines, ultrasonic sealing machines, pulse sealing machines, and heat-sealing sealing machines. Among them, heat-sealing sealing machines usually use a roll-up and unroll-down assembly to automatically feed the rolled bubble bags to the heat-sealing station. The heat-sealing components at the heat-sealing station, such as heat-sealing wheels or heat-sealing knives, perform heat sealing. When the bubble film passes through, under the set temperature, pressure, and action time, the material at the bag opening is heated and melted to form a seal.

[0004] Existing bubble bag sealing equipment, such as heat-sealing machines, suffers from problems during operation. Because bubble film is soft and easily deformed, during the long-distance dynamic feeding process from unwinding to the heat-sealing station, if the parallelism of the guide rollers is poor or the transmission tension control is inaccurate, the bubble film is prone to shifting or wrinkling. When the shifted or wrinkled film enters the heat-sealing station for pressing, the seal is prone to being crooked or the seal pattern is uneven, which can easily lead to an insecure seal or even air leakage.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] According to an embodiment of this utility model, this application discloses a bubble bag sealing device. Please refer to [link / reference]. Figure 1 The system includes a base 1, a heat-sealing assembly 2, a feeding assembly 3, a straightening assembly 4, and a drive assembly 5. All components are mounted on the base 1, which is constructed entirely of high-strength steel, resulting in a robust and stable structure. Adjustable feet are fixedly connected to the four corners of the base 1's bottom.

[0025] Please see Figure 2Preferably, the heat-sealing assembly 2 includes a first hydraulic cylinder 21 and a second hydraulic cylinder 23. The power output ends of the first hydraulic cylinder 21 and the second hydraulic cylinder 23 are respectively equipped with a first heat-sealing element 22 and a second heat-sealing element 24 that can cooperate with each other for double-sided heat sealing. Through the coordinated drive of the first hydraulic cylinder 21 and the second hydraulic cylinder 23, the first heat-sealing element 22 and the second heat-sealing element 24 can move towards each other and perform double-sided heat-press sealing of the bubble film, ensuring the uniformity and reliability of the seal.

[0026] Please see Figure 1 and Figure 2 In this embodiment, the feeding assembly 3 includes an unwinding roller 31, a positioning roller 32, and a winding roller 33 that can cooperate with each other. These three rollers are arranged sequentially along the travel direction of the bubble wrap and work together to achieve stable supply, guidance, and winding of the bubble wrap material. Both the unwinding roller 31 and the winding roller 33 can be driven by the first motor 512 to achieve active unwinding and winding of the bubble wrap, ensuring a smooth and continuous feeding process. It should be noted that in actual use, the feeding assembly 3 also needs to be equipped with a bubble wrap offset or wrinkle monitoring component, such as a camera. The camera needs to be electrically connected to the control unit. The control unit can analyze the bubble wrap status information based on the real-time images captured by the camera. When the bubble wrap offsets or wrinkles, the control unit activates the correction component 4.

[0027] Please see Figure 1 , Figure 3 and Figure 4 The correction component 4 includes two sets of clamping components 41 symmetrically distributed on both sides of the feeding component 3. Each clamping component 41 includes clamping plates and connecting plates 413. Each clamping plate includes a first clamping plate 411 and a second clamping plate 412 that cooperates with the first clamping plate 411 to clamp it. Connecting plates 413 are connected to the outer walls of both the first and second clamping plates 411 and 412. Specifically, there are two connecting plates 413, and their larger ends are connected to the driving component 5. Furthermore, a sliding rod 7 is provided on the outer wall of the clamping component 41. Two sliding sleeves 8 are slidably connected to the outer wall of the sliding rod 7, and the outer walls of the two sliding sleeves 8 are respectively fixedly connected to the first clamping plate 411 and the second clamping plate 412.

[0028] Please see Figure 3 and Figure 5The drive assembly 5 includes a first drive member 51 and a second drive member 52 for driving the two sets of clamping assemblies 41 to move synchronously. The first drive member 51 is disposed on the top seat of the base 1 and can drive the two sets of clamping assemblies 41 to move synchronously relative to each other. The first drive member 51 is preferably an existing double-acting cylinder that can be simultaneously extended and retracted by two heads. Specifically, the first drive member 51 includes a limiting shell 511. A connecting rod 513 is rotatably connected to the inner side wall of the limiting shell 511. The connecting rod 513 can be driven by a first motor 512. The two ends of the connecting rod 513 are respectively provided with threads of opposite directions and are respectively connected to two lead screw sleeves 514. Further, the outer side walls of the two lead screw sleeves 514 are connected to a connecting frame 6, and two sets of symmetrically arranged clamping assemblies 41 are respectively connected through the connecting frame 6. When the connecting rod 513 rotates, the two lead screw sleeves 514 move synchronously towards or away from each other along the lead screw axis under the guidance of the limiting shell 511, thereby driving the two sets of clamping assemblies 41 to move synchronously through the connecting frame 6, correcting deviation and straightening the bubble film. The second driving member 52 is connected to the connecting piece 413 and is used to drive the first clamping piece 411 and the second clamping piece 412 to perform clamping or releasing actions on the bubble bag.

[0029] The usage process of a bubble bag sealing device according to an embodiment of this application is as follows: In actual use, a bubble film offset or wrinkle monitoring component, such as an existing product camera, needs to be installed on the feeding component 3. The camera needs to be connected to the existing product control unit. The control unit is pre-set to analyze the bubble film status information based on the real-time images captured by the camera. When the bubble film is offset or wrinkled, the control unit activates the correction component 4. When the bubble film is offset or wrinkled, two sets of clamping components 41 symmetrically distributed at both ends of the feeding component 3 can simultaneously clamp the edges of both ends of the bubble film. Then, the first driving component 51 drives the two sets of clamping components 41 to move away from each other synchronously, correcting and straightening the offset or wrinkled bubble film. This, combined with the heat sealing component 2, improves the sealing effect. When the correction component 4 is activated, i.e., the external power supply turns on the first motor 512, the first hydraulic cylinder 21 and the second hydraulic cylinder 23 through the external switch, in actual use, the first hydraulic cylinder 21 and the second hydraulic cylinder 23 will first shorten synchronously to the preset position when the correction component 4 is activated, then the first motor 512 will rotate forward for a certain period of time, then the first hydraulic cylinder 21 and the second hydraulic cylinder 23 will extend, and the first motor 512 will rotate in reverse for a certain period of time.

[0030] The second driving members 52 on both sides shorten the first clamping piece 411 and the second clamping piece 412 in the driving clamping assembly 41 to approach each other and clamp the two sides of the bubble wrap. Then, the first driving member 51 starts, driving the two sets of clamping assemblies 41 that have clamped the bubble wrap to move away from each other synchronously, thereby generating a lateral and uniform tensile force on the bubble wrap, which can effectively correct the lateral displacement of the bubble wrap and straighten the wrinkles of the bubble wrap. The adjusted bubble wrap is then double-sided heat-sealed by the heat sealing assembly 2, resulting in a good heat sealing effect. Preferably, the first heat sealing member 22 and the second heat sealing member 24 can be existing heat sealing wheels or heat sealing knives. It should be noted that the first motor 512 is a forward and reverse reversible motor. The first motor 512, the first heat sealing member 22, the second heat sealing member 24, the first hydraulic cylinder 21 and the second hydraulic cylinder 23 are all existing products on the market and are all connected to an external power supply and an external switch.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
