Description

Technical Field

[0001] This utility model relates to equipment for producing spouted packaging bags, and more particularly to an automatic production equipment for spouted bags. Background Technology

[0002] Packaging bags are widely used in people's lives. Depending on the type of contents, packaging bags for liquid food can be sealed with a spout to facilitate consumption and reuse. A patent application with application number 2025200657248 discloses an automated production line for slanted-spout packaging bags. In this process, a bag conveyor belt transports open-ended bag components to a welding station. First, a bag opening device opens the bag opening. Then, a spout conveyor inserts one end of the spout into the bag opening. The bag opening device then releases the bag, flattening it. Finally, an ultrasonic welding device seals the spout to the bag opening, automating the slanted-spout packaging bag production. However, this production line requires waiting for the bag opening device to release the bag and for the bag to flatten before the welding device seals the bag, resulting in reduced production efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0046] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this utility model, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] Specific embodiments, such as Figure 1-5 An automatic production equipment for spouted bags is shown, including a frame 1 and a bag conveying mechanism 2 mounted on the frame 1 for conveying bag pieces 100. The bag conveying mechanism 2 is characterized by having a bag opening mechanism 3 for opening the bag opening on one side along the conveying direction, and a welding mechanism 4. The bag opening mechanism 3, away from the bag conveying mechanism 2, has a spout feeding device 5 for feeding spouted pieces 200 and inserting one end of the spouted piece 200 into the bag opening of the bag piece 100. A spout fixing mechanism 6 for fixing the spouted piece inserted into the bag is provided between the bag opening mechanism 3 and the spout feeding device 5, and the spout fixing mechanism 6 is movable along the conveying direction with the bag. During production, the bag conveying mechanism transports the bags. First, the bag opening mechanism opens the bags, then the nozzle feeding device inserts one end of the nozzle into the bag opening. The bag opening mechanism then releases the bag, while the nozzle fixing mechanism secures the nozzle inserted into the bag, moving with the bag along the conveying direction. When the bag and nozzle reach the processing station of the welding mechanism, the bag is flattened and can be directly sealed by the welding mechanism, greatly improving production efficiency. During the sealing process, the nozzle fixing mechanism returns to its original position to secure the nozzle inserted by the nozzle feeding device. This cycle repeats, resulting in high efficiency. Furthermore, there is no interference between the nozzle feeding device and the nozzle fixing mechanism and the welding mechanism, and the rational structural layout allows for the simultaneous nozzle filling and sealing of two or more bags, further increasing production efficiency.

[0049] Specifically, the welding mechanism 4 can adopt the ultrasonic welding nozzle bag heat sealing device with publication number CN118342852A, which will not be described in detail here; the bag conveying mechanism 2 can adopt the packaging bag conveying device with publication number CN218084472U, which will not be described in detail here.

[0050] In addition, the nozzle fixing mechanism 6 includes: a nozzle fixing mounting frame 61, which is mounted on the frame 1; a nozzle guide rail 62, which is mounted on the nozzle fixing mounting frame 61 along the bag conveying direction; a nozzle fixing mounting plate 63, which is movably mounted on the nozzle guide rail 62; a nozzle clamping assembly 64, which is mounted on the nozzle fixing mounting plate 63 and is used to clamp and fix the nozzle; and a nozzle driving mechanism 65, which is located between the nozzle fixing mounting frame 61 and the nozzle fixing mounting plate 63 and is used to drive the nozzle fixing mounting plate 63 to move. Specifically, the nozzle clamping assembly 64 includes an upper nozzle clamping cylinder 641 disposed on the nozzle fixing mounting plate 63, an upper nozzle clamping head 642 disposed at the output end of the upper nozzle clamping cylinder 641, a lower nozzle clamping cylinder 643 disposed vertically opposite to the upper nozzle clamping cylinder 641, and a lower nozzle clamping head 644 disposed at the output end of the lower nozzle clamping cylinder 643. The upper nozzle clamping cylinder 641 and the lower nozzle clamping cylinder 643 drive the upper nozzle clamping head 642 and the lower nozzle clamping head 644 to move towards each other to clamp and fix the nozzle.

[0051] Furthermore, the spout delivery drive mechanism 65 includes: a spout delivery timing pulley 651, which is mounted on the spout delivery fixed mounting bracket 61; a spout delivery timing belt 652, which is movably sleeved on the spout delivery timing pulley 651 along the bag conveying direction; the spout delivery fixed mounting plate 63 is connected to the spout delivery timing belt 652; and a spout delivery drive motor 653, which drives the spout delivery timing pulley 651 to rotate. This enables the spout delivery fixed mounting plate 63 to reciprocate along the bag conveying direction.

[0052] More specifically, the nozzle feeding device 5 includes: a nozzle feeding mounting frame 51, which is mounted on the frame 1; a nozzle feeding mechanism 52, which is mounted on the nozzle feeding mounting frame 51 and used to transport nozzle components; and a nozzle transfer mechanism 53, which is mounted on the nozzle feeding mounting frame 51 and used to clamp the nozzle components on the nozzle feeding mechanism 52 and insert one end of the nozzle component into the bag opening of the bag component. This achieves automated nozzle feeding and automatically inserts one end of the nozzle component into the bag opening, resulting in high production efficiency.

[0053] Further, the nozzle transfer mechanism 53 includes: a rotating mounting plate 531, which is horizontally rotatably mounted on the nozzle feeding mounting frame 51; a turntable drive 532, which drives the rotating mounting plate 531 to rotate; a nozzle clamping member 533, which clamps and fixes the nozzle; and a horizontal drive member 534, which is mounted on the rotating mounting plate 531 and drives the nozzle clamping member 533 to translate, so as to insert one end of the nozzle into the bag opening of the bag. Specifically, the nozzle clamping member 533 is a clamping cylinder, and the horizontal drive member 534 is a telescopic cylinder. This achieves automatic insertion of one end of the nozzle into the bag opening of the bag.

[0054] Furthermore, there are two horizontal drive members 534, and the driving directions of the two horizontal drive members 534 are opposite. The two nozzle clamping members 533 are respectively disposed at the driving ends of the two horizontal drive members 534. That is, the nozzle part is picked up simultaneously and one end of the nozzle part is automatically inserted into the bag opening of the bag part, thereby improving production efficiency.

[0055] Specifically, the nozzle feeding mechanism 52 includes: a vibratory feeding device 521 for conveying nozzle components; the vibratory feeding device 521 can be a conventional vibratory feeding machine, which will not be described in detail here; a nozzle feeding mounting plate 522, which is mounted on the nozzle feeding mounting frame 51; two nozzle feeding fixing cylinders 523, which are arranged vertically opposite each other on the nozzle feeding mounting plate 522; and nozzle feeding fixing members 524, which are located at the output end of the nozzle feeding fixing cylinders 523 and are used to fix the nozzle components conveyed by the vibratory feeding device 521. The nozzle components are clamped and fixed by the two vertically arranged nozzle feeding fixing members 524 moving towards each other. After the nozzle clamping member 533 removes the nozzle component, the two nozzle feeding fixing members 524 move away from each other, allowing the next nozzle component to be conveyed to the discharge port and then clamped and fixed, thus realizing automated, one-by-one feeding of nozzle components.

[0056] More specifically, the bag opening mechanism 3 includes: a bag opening mounting frame 31, which is mounted on the frame 1; and a bag opening suction cup assembly 32, which is mounted on the bag opening mounting frame 31, including an upper bag opening drive 321 mounted on the bag opening mounting frame 31, a lower bag opening drive 322 disposed vertically opposite to the upper bag opening drive 321, an upper bag opening suction cup 323 disposed at the output end of the upper bag opening drive 321, and a lower bag opening suction cup 324 disposed at the output end of the lower bag opening drive 322. The lower bag opening drive 322 and the lower bag opening drive 322 respectively drive the upper bag opening suction cup 323 and the lower bag opening suction cup 324 to move towards or away from each other. The upper bag opening drive 321 and the lower bag opening drive 322 are telescopic cylinders.

[0057] As an optional embodiment of this application, the bag-opening suction cup assembly 32 consists of two sets, which are arranged on the bag opening mounting frame 31 along the bag conveying direction. Correspondingly, the nozzle clamping assembly 64 consists of two sets, each corresponding to one of the two bag-opening suction cup assemblies 32; the nozzle clamping member 533 consists of two parts, each corresponding to one of the two bag-opening suction cup assemblies 32; and the welding mechanism 4 consists of two parts, each corresponding to one of the two bag-opening suction cup assemblies 32. This structural layout is reasonable and can simultaneously realize the nozzle filling and bag sealing processes for two or more bags, resulting in higher production efficiency.

[0058] Specifically, it also includes a sealing mechanism 7 located on one side of the bag conveying mechanism 2. The sealing mechanism 7 may be a sealing device disclosed in publication number CN218084473U, which will not be described in detail here.

Furthermore, due to different industry naming conventions, it is not limited to the above names or English names. Any methods or structures similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
