Description

Technical Field

[0001] This utility model relates to the field of paper bag manufacturing technology, and in particular to a paper bag forming, bottom pasting, and card placement machine. Background Technology

[0002] Paper bags are bags made primarily of paper and are widely used for holding items such as shopping bags, gift bags, and food bags. They are not only practical household items but also an environmentally friendly choice. As people's environmental awareness continues to increase, the use of paper bags instead of plastic bags is becoming increasingly common. A paper bag bottom-gluing machine is a device that glues the bottoms of manufactured paper bags. Typically, unsealed paper bags are first cut, then an unfolding mechanism is inserted into the bottom of the paper bag, unfolding both sides. Finally, the unfolded paper bag is glued to the bottom. Because existing paper bag conveying systems cannot achieve the goal of conveying paper bags individually, additional operators are needed to constantly monitor the conveyor belt. When multiple paper bags become blocked and stop during conveying, manual adjustment and sorting are required, which is not only time-consuming and labor-intensive but also affects the progress and production efficiency of the bottom-gluing process. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a paper bag forming, bottom pasting, and card placement machine.

Detailed Implementation

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown, a paper bag forming and bottom-gluing card-placement machine of this utility model includes a first bottom-gluing mechanism 1, a second bottom-gluing mechanism 2 spaced apart from the first bottom-gluing mechanism 1, and a material collection mechanism 3 disposed between the first bottom-gluing mechanism 1 and the second bottom-gluing mechanism 2. The first bottom-gluing mechanism 1 and the second bottom-gluing mechanism 2 have the same structure. The first bottom-gluing mechanism 1 includes a base frame 11, a conveyor belt 12 disposed on the base frame 11, and a carrying mold 13 driven and connected to the conveyor belt 12. Multiple carrying molds 13 are provided and are arranged at intervals along the length direction of the conveyor belt 12. A feeding conveyor belt 14 is provided on the side of the base frame 11. The feeding conveyor belt 14 is used to transport the paper bags to be processed to the conveyor belt 12 so that the paper bags with open mouths are placed on the outside of the carrying mold 13.

[0025] During operation, paper bags to be processed are first conveyed via the feeding conveyor belt 14. An external picking mechanism removes a single paper bag from the feeding conveyor belt 14 and moves it to an external suction fan. The external suction fan opens the opening of the single paper bag to prepare it for bagging. Then, another external picking mechanism picks up the paper bags waiting to be bagged and moves them to the conveyor belt 12. Since multiple carrying molds 13 are arranged at intervals along the length of the conveyor belt 12, multiple cut and unsealed paper bags are inserted into the multiple carrying molds 13 respectively, so that multiple paper bags can be conveyed one by one using the multiple carrying molds 13. This invention effectively avoids the disruption caused by bag blockage during the conveying process, which would hinder the progress of bottom sealing. Multiple paper bags undergo a series of operations during transport, including folding the short side, applying glue to the long side, folding the long side over the short side, and unloading the paper bags. Furthermore, the first bottom sealing mechanism 1 and the second bottom sealing mechanism 2 have the same structure and working principle, enabling synchronized and efficient operation. The paper bags produced by both mechanisms are then uniformly collected and discharged by the collecting mechanism 3, facilitating subsequent packaging and shipping operations. This achieves fully automated paper bag forming and bottom sealing, with high efficiency and coordination between the mechanisms. This invention uses multiple carrier molds 13 to separately transport paper bags along the length of the conveyor belt 12, avoiding blockages caused by excessive transport. The unified discharge by the collecting mechanism 3 ensures a smooth and orderly workflow, improving production efficiency.

[0026] The bearing mold 13 in this embodiment includes a base frame 131, a support member 132 disposed on the base frame 131, and a drive cylinder 133 drivenly connected to the support member 132. There are multiple drive cylinders 133 arranged around the circumference of the base frame 131, with adjacent drive cylinders 133 spaced apart. There are multiple support members 132 arranged in a polygonal shape. Specifically, since multiple drive cylinders 133 are arranged around the circumference of the base frame 131, and adjacent drive cylinders 133 are spaced apart, the multiple drive cylinders 133 drive multiple support members 132 to adaptably extend and contract in the volume space, so that the multiple support members 132 can be arranged into a polygonal shape, so that the four corners of the paper bag are stretched open. Preferably, there are four drive cylinders 133 and four support members 132. The four support members 132 can be arranged into a polygonal shape such as a rectangle or a square, so as to better adjust the distance between the multiple support members 132 according to the actual work needs, effectively unfold and support paper bags of different sizes, so that the paper bag is completely flattened, providing stable working convenience for subsequent bottom gluing work. Then, the conveyor belt 12 drives the multiple support members 132 to move through the base frame 131, thereby moving the paper bag to the corresponding work station for processing.

[0027] In this embodiment, the central axis of the driving cylinder 133 is perpendicular to the central axis of the support member 132. The support member 132 extends away from the driving cylinder 133, and a suction cup 134 is provided at the end of the support member 132 away from the driving cylinder 133. Specifically, the central axis of the driving cylinder 133 is perpendicular to the central axis of the support member 132, so that the support member 132 extends upward away from the driving cylinder 133. The support member 132 moves back and forth and extends and retracts freely by being driven by the driving cylinder 133, thereby pushing the four corners of the paper bag to be fully unfolded. The suction cup 134 is provided at the end of the support member 132 away from the driving cylinder 133. The suction force of the suction cup 134 is used to adhere and fix the short sides of the paper bag. Hot melt adhesive or water-based adhesive is sprayed on the other two long sides, and then the long sides are folded onto the short sides to achieve mutual adhesion and fixation between the long and short sides, thus completing the bottom forming of the paper bag.

[0028] The material collection mechanism 3 of this embodiment includes a folding component 31, a conveying component 32 used in conjunction with the folding component 31, and a discharge component 33 used in conjunction with the conveying component 32. The folding component 31 includes a first feeding belt 311 and a second feeding belt 312 spaced apart from the first feeding belt 311. The first feeding belt 311 and the second feeding belt 312 are inclined and have a structure that is narrower at the top and wider at the bottom. The narrow end between the first feeding belt 311 and the second feeding belt 312 is close to the conveying component 32, and the wide end between the first feeding belt 311 and the second feeding belt 312 is close to the bearing mold 13. Specifically, firstly, the first feeding belt 311 and the second feeding belt 312 are spaced apart, and the first feeding belt 311 and the second feeding belt 312 are arranged at an angle with a structure that is narrower at the top and wider at the bottom, so that the paper bag that has completed the bottom gluing work can smoothly enter the space between the first feeding belt 311 and the second feeding belt 312 through the wide end. The paper bag is folded and flattened by the first feeding belt 311 and the second feeding belt 312, so that the paper bag changes from an unfolded state to a flat state. Then, it is conveyed to the conveying component 32 through the narrow end between the first feeding belt 311 and the second feeding belt 312. Then, it is conveyed by the conveying component 32 into the discharge component 33, and finally, it is uniformly output by the discharge component 33.

[0029] The conveying component 32 of this embodiment includes a third feeding belt 321 and a fourth feeding belt 322 that is spaced apart from and parallel to the third feeding belt 321. A feeding channel 323 is formed between the third feeding belt 321 and the fourth feeding belt 322. The fourth feeding belt 322 is located above the third feeding belt 321. The third feeding belt 321 is connected to the second feeding belt 312. A tensioning wheel 324 is rotatably arranged between the third feeding belt 321 and the second feeding belt 312. Specifically, the third feeding belt 321 and the fourth feeding belt 322 are arranged vertically and parallel to each other, and a feeding channel 323 is formed between the third feeding belt 321 and the fourth feeding belt 322. The fourth feeding belt 322 is located above the third feeding belt 321, so that the flat paper bag is transported smoothly in the feeding channel 323 in a horizontal position. The third feeding belt 321 is connected to the second feeding belt 312, and a tensioning wheel 324 is rotatably arranged between the third feeding belt 321 and the second feeding belt 312. The structure is compact and reasonably designed. Since the third feeding belt 321 and the second feeding belt 312 will experience elastic elongation and permanent elongation (creep) during operation, the tensioning wheel 324 can adjust the tension at any time to compensate for these length changes, so that the belt always maintains a taut state, which can maintain constant tension and reduce impact and vibration.

[0030] The discharging assembly 33 of this embodiment includes a fifth feeding belt 331 and a counter 332 used in conjunction with the fifth feeding belt 331. The fifth feeding belt 331 is located below the third feeding belt 321, and the counter 332 is located above the fifth feeding belt 331. Specifically, the fifth feeding belt 331 is located below the third feeding belt 321 to facilitate the smooth falling of paper bags onto the fifth feeding belt 331. The fifth feeding belt 331 transports the paper bags past the position of the counter 332, allowing the counter 332 to record and count the number of paper bags in real time. Finally, the fifth feeding belt 331 transports the paper bags out.

[0031] In this embodiment, a lifting cylinder 15 is provided at one end of the base frame 11 near the folding assembly 31. The output end of the lifting cylinder 15 is driven to connect to a lifting seat 16. The lifting seat 16 is driven by the lifting cylinder 15 to move up and down relative to the support member 132. Friction pads 17 are provided on both sides of the lifting seat 16. Specifically, the output end of the lifting cylinder 15 is driven to connect to the lifting seat 16, and friction pads 17 are provided on both sides of the lifting seat 16. The friction pads 17 fit against the inner wall of the paper bag, with a large contact area, increasing frictional resistance, effectively filling small gaps, and improving the tightness and stability of the contact surface. This makes it less likely for the paper bag to shift or move on the lifting seat 16. The lifting seat 16 is driven by the lifting cylinder 15 to move up and down relative to the support member 132, thereby causing the paper bag to detach from the support member 132 and unfold, making it easy to remove the paper bag from the support member 132.

[0032] In this embodiment, the conveyor belt 12 has a connecting block 18, which is connected to the base frame 131. Specifically, the conveyor belt 12 is connected to the base frame 131 through the connecting block 18, thereby driving the support member 132 set on the base frame 131 to move as a whole. The structure is compact and the design is reasonable.

[0033] The base frame 131 of this embodiment includes a longitudinal beam 1311, a crossbeam 1312 connected to the longitudinal beam 1311, and a base 1313 disposed on the crossbeam 1312. The longitudinal beam 1311 and the crossbeam 1312 are arranged perpendicularly. The crossbeam 1312 is provided with a support clamping seat 1314, which is clamped and sleeved on the middle part of the base 1313. Specifically, the crossbeam 1312 is positioned above the longitudinal beam 1311, and the longitudinal beam 1311 and the crossbeam 1312 are arranged perpendicularly to each other in a cross shape, resulting in high structural stability. The crossbeam 1312 is stably clamped and sleeved on the middle of the base 1313 by the support clamping seat 1314, effectively fixing the position of the base 1313 on the crossbeam 1312, thereby improving the overall structural strength of the base frame 131, so that the four drive cylinders 133 can be stably arranged around the circumference of the base 1313, ensuring stable and reliable operation.

[0034] The base frame 11 in this embodiment is made of aluminum alloy. Specifically, the density of aluminum alloy is about 2.7 g / cm³, which is only about one-third that of steel, but its tensile strength can reach 200-500 MPa, which is comparable to that of ordinary structural steel. This allows the weight to be reduced by about 40% under the same load-bearing capacity. A dense aluminum oxide protective film naturally forms on the aluminum surface, which can prevent rust in most environments without the need for additional anti-corrosion treatment. Aluminum alloy can be quickly formed through cold working, cutting, hole machining and other processes, and can be quickly assembled and disassembled using standardized connectors (such as bolts and clips), which is suitable for on-site debugging and secondary use, thus improving the performance of the base frame 11.
