Description

Technical Field

[0001] This utility model relates to the field of paper bag manufacturing technology, and in particular to a paper bag forming and bottom-gluing device. 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 used to glue 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 and unfolds the sides. Finally, the unfolded paper bag is glued to the bottom. However, in existing paper bag bottom-gluing machines, the paper bag conveying process cannot achieve the goal of conveying paper bags individually. Operators need to constantly monitor the conveying of paper bags to prevent multiple paper bags from becoming clogged and disorderly during conveying, which affects the overall progress of bottom-gluing. This is time-consuming, labor-intensive, and reduces production efficiency. 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 and sealing device.

[0004] To achieve the above objectives, this utility model provides a paper bag forming and bottom-gluing device, comprising a base frame, a conveyor belt disposed on the base frame, and a carrying mold connected to the conveyor belt. Multiple carrying molds are provided and arranged at intervals along the length of the conveyor belt. Each carrying mold includes a base frame, a support member disposed on the base frame, and a drive cylinder connected to the support member. A feeding conveyor belt is provided on the side of the base frame, which transports the paper bags to be processed to the carrying mold, so that the paper bags with open openings are fitted over the outside of the support member.

[0005] Preferably, there are multiple drive cylinders arranged around the circumference of the base frame, with adjacent drive cylinders spaced apart. There are also multiple support members arranged in a polygonal shape.

[0006] Preferably, the central axis of the driving cylinder is perpendicular to the central axis of the support member, the support member extends away from the driving cylinder, and a suction cup is provided at the end of the support member away from the driving cylinder.

[0007] Preferably, the base frame is equipped with a lifting cylinder, the output end of which is driven to connect to a lifting seat. The lifting seat is driven by the lifting cylinder to move up and down relative to the support member. Friction pads are provided on both sides of the lifting seat.

[0008] Preferably, the conveyor belt body is provided with a connecting block, and the connecting block is connected to the base frame.

[0009] Preferably, the base frame is made of aluminum alloy.

[0010] The beneficial effects of this utility model are: by using multiple carrier molds to separately transport paper bags one by one along the length of the conveyor belt, the problem of bag blockage and disorder that hinders normal operation is effectively avoided, ensuring the efficient progress of paper bag bottom sealing and improving production efficiency.

Detailed Implementation

[0016] 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.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1 to 3As shown, a paper bag forming and bottom-gluing device of this utility model includes a base frame 1, a conveyor belt 2 disposed on the base frame 1, and a carrying mold 3 driven and connected to the conveyor belt 2. Multiple carrying molds 3 are provided and arranged at intervals along the length direction of the conveyor belt 2. Each carrying mold 3 includes a base frame 31, a support member 32 disposed on the base frame 31, and a driving cylinder 33 driven and connected to the support member 32. A feeding conveyor belt 4 is provided on the side of the base frame 1. The feeding conveyor belt 4 is used to transport the paper bags to be processed to the carrying mold 3 so that the paper bags with the openings are fitted over the outside of the support member 32.

[0019] During operation, paper bags to be processed are first conveyed via the feeding conveyor belt 4. An external picking mechanism removes individual paper bags from the feeding conveyor belt 4 and moves them to an external suction fan. The external suction fan opens the opening of each paper bag, preparing it for bagging. Then, another external picking mechanism picks up the bag awaiting bagging and moves it to the conveyor belt 2. Multiple carrying molds 3 are arranged at intervals along the length of the conveyor belt 2. Multiple cut, unsealed paper bags are inserted into the carrying molds 3, allowing for separate conveying of multiple paper bags one by one. This effectively avoids bag blockage and disorder during transport, which would affect the bag sealing process, ensuring efficient and orderly conveying. This invention, by using multiple carrying molds 3 to separate paper bags one by one along the length of the conveyor belt 2, effectively avoids bag blockage and disorder that would hinder normal operation, ensuring efficient bag sealing and improving production efficiency.

[0020] In this embodiment, there are multiple drive cylinders 33, which are arranged around the circumference of the base frame 31. Adjacent drive cylinders 33 are arranged at intervals. There are multiple support members 32, which are arranged in a polygonal shape. Specifically, since multiple drive cylinders 33 are arranged around the circumference of the base frame 31, and adjacent drive cylinders 33 are spaced apart, the multiple drive cylinders 33 drive multiple support members 32 to adaptably extend and contract in the volume space, so that the multiple support members 32 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 33 and four support members 32. The four support members 32 can be arranged into a rectangle, square or other polygonal shape, so as to better adjust the distance between the multiple support members 32 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 2 drives the multiple support members 32 to move through the base frame 31, thereby moving the paper bag to the corresponding work station for processing.

[0021] In this embodiment, the central axis of the driving cylinder 33 is perpendicular to the central axis of the support member 32. The support member 32 extends away from the driving cylinder 33, and a suction cup 34 is provided at the end of the support member 32 away from the driving cylinder 33. Specifically, the central axis of the driving cylinder 33 is perpendicular to the central axis of the support member 32, so that the support member 32 extends upward away from the driving cylinder 33. The support member 32 moves back and forth and extends freely by being driven by the driving cylinder 33, thereby pushing the four corners of the paper bag to be fully unfolded. The suction cup 34 is provided at the end of the support member 32 away from the driving cylinder 33. The suction force of the suction cup 34 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 to the short sides to achieve mutual adhesion between the long and short sides and complete the bottom forming of the paper bag.

[0022] In this embodiment, the base frame 1 is equipped with a lifting cylinder 5. The output end of the lifting cylinder 5 is driven to connect to a lifting seat 51. The lifting seat 51 is driven by the lifting cylinder 5 to move up and down relative to the support member 32. Friction pads 52 are provided on both sides of the lifting seat 51. Specifically, the output end of the lifting cylinder 5 is driven to connect to the lifting seat 51, and friction pads 52 are provided on both sides of the lifting seat 51. The friction pads 52 are in close contact with the inner wall of the paper bag, with a large contact area, which increases the frictional resistance, making it difficult for the paper bag to shift or move on the lifting seat 51. The lifting seat 51 is driven by the lifting cylinder 5 to move up and down relative to the support member 32, thereby causing the paper bag to detach from the support member 32 and unfold, making it easy to remove the paper bag from the support member 32.

[0023] In this embodiment, the conveyor belt 2 has a connecting block 21, which is connected to the base frame 31. Specifically, the conveyor belt 2 is connected to the base frame 31 through the connecting block 21, thereby driving the support member 32 set on the base frame 31 to move as a whole. The structure is compact and the design is reasonable.

[0024] The base frame 1 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 surface of aluminum, 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), making it suitable for on-site debugging and secondary use, thus improving the performance of the base frame 1.
