Description

[Technical Field]

[0001] This utility model belongs to the technical field of nozzle packaging bag production equipment, and in particular relates to an automatic production line for oblique nozzle packaging bags. [Background Technology]

[0002] Packaging bags are widely used in people's lives. Depending on the type of contents, packaging bags for liquid foods can be sealed with a spout to facilitate drinking and repeated use. Existing packaging bag sealing devices generally use hot pressing to fuse the packaging bag and the beveled part of the spout. This welding method is suitable for packaging bags of different materials. However, to be more environmentally friendly, current packaging bags are generally made of a single material. For single-material packaging bags, when using hot pressing to weld the spout, the heat is transferred from the outside in. If the temperature is too low, the bonding force between the packaging bag and the spout may be insufficient, resulting in a weak weld. If the temperature is too high, the outside of the packaging bag may melt and deform, compromising product processing quality. Furthermore, hot pressing requires a long pressing time, leading to low processing efficiency. [Utility Model Content]

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.

[0065] Specific embodiments, such as Figure 1-11The diagram illustrates an automated production line for angled-spout packaging bags, comprising a frame 1 and a second bag conveying mechanism 3 mounted on the frame 1 for conveying bag components. Along the conveying direction, one side of the second bag conveying mechanism 3 is sequentially equipped with: a bag opening device 4 for opening the bag opening on the second bag conveying mechanism 3; a nozzle conveying device 5 for conveying nozzle components and inserting the angled end of the nozzle component into the bag opening; and an ultrasonic welding device 6 for sealing the nozzle component and the bag opening. During production, the bag components are opened via the conveyor belt of the second bag conveying mechanism. First, the bag opening device opens the bag opening, then the nozzle conveying device inserts the angled end of the nozzle component into the bag opening, and finally, the ultrasonic welding device seals the nozzle component and the bag opening, thus achieving automated processing of angled-spout packaging bags. Furthermore, this application uses an ultrasonic welding device to weld the nozzle component and the bag component, which allows for simultaneous heating from both inside and outside, enabling rapid welding of the inner side of the bag component and the nozzle component, ensuring product processing quality and improving processing efficiency.

[0066] Specifically, the ultrasonic welding device 6 includes: a welding mounting frame 61; an upper ultrasonic welding assembly 62, which is movably mounted on the welding mounting frame 61 in a vertical direction; and a lower ultrasonic welding assembly 63, which is movably mounted on the welding mounting frame 61 in a vertical direction and is arranged opposite to the upper ultrasonic welding assembly 62, and cooperates with the upper ultrasonic welding assembly 62 to seal the bag opening of the bag with the nozzle inserted on the second bag conveying mechanism 3. By using the upper ultrasonic welding assembly 62 and the lower ultrasonic welding assembly 63 arranged vertically opposite to each other, the upper and lower sides of the nozzle and the bag are simultaneously heat-sealed, ensuring processing quality and improving processing efficiency.

[0067] Additionally, the upper ultrasonic welding assembly 62 includes: an upper movable slide rail 621, which is vertically mounted on the welding mounting frame 61; an upper ultrasonic transducer 622, which is movably mounted on the upper movable slide rail 621, with its output end facing downwards; an upper welding drive member 623, mounted on the welding mounting frame 61, for driving the upper ultrasonic transducer 622; and an upper welding head mold 624, located at the output end of the upper ultrasonic transducer 622, with an upper V-shaped welding groove 6241 at the end of the upper welding head mold 624 away from the upper ultrasonic transducer 622, capable of fitting against the outer wall of the bevel end of the nozzle. Optionally, the upper welding drive member 623 is a telescopic cylinder, which drives the upper welding head mold 624 to move on the upper movable slide rail 621 via its telescopic end, ensuring that the upper welding head mold 624 is in the correct position for welding and completing heat sealing in one operation. In addition, an upper V-shaped welding groove 6241 is provided, and the upper V-shaped welding groove 6241 fits well with the outer wall of the oblique nozzle end, effectively ensuring sufficient welding between the inner wall of the bag and the outer wall of the oblique nozzle end, and effectively ensuring sealing performance.

[0068] Further, the lower ultrasonic welding assembly 63 includes: a lower movable slide rail 631, which is vertically mounted on the welding mounting frame 61; a lower ultrasonic transducer 632, which is movably mounted on the lower movable slide rail 631, with the output end of the lower ultrasonic transducer 632 facing upwards; a lower welding drive member 633, which is mounted on the welding mounting frame 61 for driving the lower ultrasonic transducer 632 to move; and a lower welding head mold 634, which is located at the output end of the lower ultrasonic transducer 632, with a lower V-shaped welding groove 6341 at the end of the lower welding head mold 634 away from the lower ultrasonic transducer 632, which can fit against the outer wall of the lower surface of the bevel end of the nozzle. Optionally, the lower welding drive component 633 is a telescopic cylinder. The telescopic end of the lower welding drive component 633 drives the lower welding head mold 634 to move on the lower movable slide rail 631, ensuring that the lower welding head mold 634 is aligned with the upper welding head mold 624, guaranteeing the lower welding head mold 634 is properly positioned for welding and completing heat sealing in one step. Additionally, a lower V-shaped welding groove 6341 is provided, and the lower V-shaped welding groove 6341 fits well with the outer wall of the angled nozzle end, effectively ensuring sufficient welding between the inner wall of the bag and the outer wall of the angled nozzle end, effectively guaranteeing sealing performance. Both the upper and lower ultrasonic transducers described in this invention are commercially available products. During the operation of the upper and lower ultrasonic transducers of this invention, heat energy is generated by the mechanical vibration of ultrasonic waves, allowing the bag with a single material and multi-layer structure to be heated simultaneously inside and out when welding to the nozzle. Pressure is applied simultaneously with heating, causing a strong weld to form between the innermost layer of the bag and the outer wall of the nozzle in a short time.

[0069] More specifically, the automatic production line for angled-mouth packaging bags also includes a bag corner-cutting device 7 located in front of the bag opening device 4.

Optionally, the cutter drive 74 is a telescopic cylinder, whose telescopic end drives the upper cutter 73 to move, cooperating with the lower cutter 72 to achieve automated corner cutting, improving production efficiency, and the waste is recovered through the waste discharge plate 75.

[0070] Further, the bag opening device 4 includes: a bag opening mounting frame 41, which is mounted on the frame 1; two bag opening suction cup assemblies 42, which are vertically opposite each other on the bag opening mounting frame 41; and a bag opening transverse conveyor line 43, which is mounted on the bag opening mounting frame 41 and is used to drive the two bag opening suction cup assemblies 42 to move horizontally along the conveying direction of the second bag conveying mechanism 3. Specifically, the bag opening suction cup assembly 42 includes suction cups. In use, the upper and lower suction cups respectively suck up the upper and lower layers of the bag to open the bag opening, and then the bag is conveyed to the nozzle conveying device 5 by the second bag conveying mechanism 3 via the bag opening transverse conveyor line 43. Specifically, both the second bag conveying mechanism and the bag opening transverse conveyor line 43 are belt conveyors, which are existing conveying equipment and will not be described in detail here.

[0071] Furthermore, the nozzle conveying device 5 includes: a nozzle conveying mounting frame 51, which is mounted on the frame 1; a vibrating feeding device 52, which is mounted on the nozzle conveying mounting frame 51 and is used for feeding nozzle parts. The vibrating feeding device 52 can be a direct vibrating feeding machine, which is existing technology and will not be described in detail here; a nozzle conveying baffle 53, which is movably mounted at the outlet of the vibrating feeding device 52 along a conveying direction perpendicular to the vibrating feeding device 52; a nozzle baffle driving member 54, which is mounted on the nozzle conveying mounting frame 51 and is used to drive the nozzle conveying baffle 53 to move; and a nozzle transfer mechanism 55, which is mounted on the nozzle conveying mounting frame 51 and is used to clamp the nozzle parts on the vibrating feeding device 52 and insert the oblique end of the nozzle parts into the bag opening of the bag parts. Specifically, the nozzle transfer mechanism 55 includes: a nozzle transfer slide rail 551, which is mounted on the nozzle conveying mounting frame 51; a nozzle transfer mounting component 552, which is movably mounted on the nozzle transfer slide rail 551; a nozzle transfer drive component 553, which drives the nozzle transfer mounting component 552 to move; and a nozzle clamping component 554, which is mounted on the nozzle transfer mounting component 552 and is used to clamp the nozzle. Optionally, both the nozzle baffle drive component and the nozzle transfer drive component are telescopic cylinders. The nozzle conveying device 5 also includes a vibrating feeder.

[0072] Specifically, a sealing device 8 is also provided on one side of the second bag conveying mechanism 3, located behind the ultrasonic welding device 6. The sealing device 8 further reinforces the bag. The sealing device 8 is disclosed in patent application publication number CN218084473U and will not be described in detail here.

[0073] Additionally, a bag transfer and loading mechanism 2 is included. This mechanism comprises: a first bag conveying mechanism 21 for conveying bags; a rotating tray 22 rotatably mounted at one end of the first bag conveying mechanism 21 for receiving and placing bags conveyed by the first bag conveying mechanism 21; and a tray driving mechanism 23 located at one end of the first bag conveying mechanism 21 for driving the rotating tray 22 to rotate. In use, the first bag conveying mechanism conveys the bags to be processed, which are then received and placed on the rotating tray. The tray driving mechanism then drives the rotating tray and the bags on it to rotate to any set angle, thus achieving automatic adjustment of the bag placement angle. This facilitates subsequent corner cutting processing of the bags, offering strong versatility, convenient adjustment, and a small footprint, reducing equipment size.

[0074] Specifically, the pallet driving mechanism 23 includes: a pallet driving mounting frame 231, which is disposed at one end of the first bag conveying mechanism 21; and a pallet rotation driving component 232, which is disposed on the pallet driving mounting frame 231 and is used to drive the rotating pallet 22 to rotate. Optionally, the pallet rotation driving component 232 is a rotary motor, the rotation output end of which is connected to the rotating pallet 22 to drive the rotating pallet 22 to rotate.

[0075] In addition, the pallet drive mechanism 23 further includes: a pallet lifting guide rail 233, which is vertically mounted on the pallet drive mounting frame 231, and the pallet rotation drive component 232 is movably mounted on the pallet lifting guide rail 233; and a pallet lifting drive component 234, which is mounted on the pallet drive mounting frame 231 and is used to drive the pallet rotation drive component 232 to move vertically. Optionally, the pallet lifting drive component 234 can be a telescopic cylinder, which drives the pallet rotation drive component 232 to move on the pallet lifting guide rail 233 through its telescopic end; preferably, the pallet lifting drive component 234 uses a motor to drive a lead screw to rotate, thereby driving the pallet rotation drive component 232 to move on the pallet lifting guide rail 233, making the lifting more stable. In use, the first bag conveying mechanism 21 conveys the bags to the rotating pallet 22. First, the pallet lifting drive 234 drives the pallet rotation drive 232 and the rotating pallet 22 to lift. Then, the pallet rotation drive 232 drives the rotating pallet 22 to rotate and adjust the angle of the bags. Finally, the bags are transferred to the next processing conveyor line by a robotic arm or other transfer equipment. After the bags are taken away, they are reset. This achieves automated adjustment of the bag angle, which is highly efficient and has a small overall size and footprint.

[0076] Furthermore, the pallet drive mounting frame 231 is equipped with a position detection switch 24, and the pallet rotation drive component 232 is equipped with a position sensing plate 25 corresponding to the position detection switch 24. When the pallet lifting drive component 234 drives the pallet rotation drive component 232 to move until the position sensing plate 25 is opposite to the position detection switch 24, the pallet lifting drive component 234 stops. At this time, the height of the rotating pallet 22 is level with the feeding height of the first bag conveying mechanism 21, resulting in a higher degree of automation.

[0077] More specifically, the rotating tray 22 includes: a base plate 221 for receiving and placing bags; a first push plate 222 movably disposed on the base plate 221 along its length; and two second push plates 223 movably disposed opposite each other on the base plate 221 along its width.

[0078] Furthermore, the rotating tray 22 further includes: a first pusher plate drive 224, which is disposed on the placement base plate 221 for driving the first pusher plate 222 to move; and a second pusher plate drive 225, which is disposed on the placement base plate 221 for driving the two second pusher plates 223 to move towards each other or away from each other. Optionally, the first pusher plate drive 224 and the second pusher plate drive 225 can be telescopic cylinders, which drive the first pusher plate 222 and the second pusher plate 223 to move and adjust through their telescopic ends, resulting in a higher degree of automation and efficiency.

[0079] Furthermore, the bag transfer and feeding mechanism also includes a bag conveying mechanism 26, which comprises: a conveying mounting frame 261, disposed above the rotating tray 22; a conveyor belt 262, horizontally disposed on the conveyor mounting frame 261; a first conveyor mounting plate 263, disposed on the conveyor belt 262; a conveyor drive 264, vertically disposed on the first conveyor mounting plate 263; a second conveyor mounting plate 265, disposed at the output end of the conveyor drive 264, which drives the second conveyor mounting plate 265 to move vertically; and a suction cup 266, disposed on the second conveyor mounting plate 265, for picking up bags placed on the rotating tray 22. Specifically, the conveyor belt 262 includes a rotating motor, a rotating wheel, and a conveyor belt sleeved on the rotating wheel, and the first conveyor mounting plate 263 is disposed on the conveyor belt to achieve translation. Optionally, the transfer drive component 264 is a telescopic cylinder, the telescopic end of which is connected to the second transfer mounting plate 265, for driving the material-picking suction cups 266 to lift and pick up the bag. Specifically, there are four material-picking suction cups 266, and the four material-picking suction cups 266 are arranged in a rectangular shape to facilitate the picking up of the bag and avoid deformation of the bag.

The first conveyor belt 211 includes a rotating motor, a rotating wheel, and a conveyor belt sleeved on the rotating wheel. The automatic bag feeding device 212 is prior art disclosed in the applicant's invention patent application with publication number CN118205263A, and will not be described in detail here.

[0082] In addition, the first conveyor belt 211 is provided with baffles 281 arranged along the conveying direction, with two baffles 281 arranged opposite each other. The discharge end of the first conveyor belt 211 is provided with a pusher plate 282 arranged opposite to the baffles 281, and a pusher plate drive member 283 for driving the pusher plate 282 to move closer to or away from the opposite baffles 281.
