Description

Technical Field

[0001] The present application relates to the field of packaging bags, and in particular to a production device for small-port bubble film packaging bags. Background Art

[0002] When transporting long strip products, in order to prevent them from being damaged or scratched, they need to be packed in bags with cushioning effects. For example, a car bumper is a strip product with a length greater than 1m and a large volume. When packing, a large-opening bag is used (see Figure 1 ), a packaging bag with a large opening 12 includes a packaging bag body 1, on which a large opening 12 extending along the length direction of the packaging bag body 1 is provided. During packaging, after the car bumper is put into the packaging bag with the large opening 12, the opening is sealed with tape to prevent the car bumper from falling out, which makes packaging more troublesome, and the large opening 12 of the packaging bag is difficult to be completely sealed with the tape, so that a large area of ​​the bumper is exposed, and the protection effect is poor. Utility Model Content

[0003] In order to improve the protective effect of packaging bags on strip products and facilitate packaging at the same time, the present application provides a production equipment for small-port bubble film packaging bags.

[0004] The present application provides a production device for small-port bubble film packaging bags, which adopts the following technical solution:

[0005] A production device for small-port bubble film packaging bags is used to produce the small-port bubble film packaging bags for the above-mentioned strip products, comprising a folding and sealing device and a port sealing and cutting device. The folding and sealing device folds the bubble film coil and then seals the folded edges, and the port sealing and cutting device seals the bubble film coil with the folded edges sealed along the width direction and then cuts it.

[0006] By adopting the above technical scheme, the bubble film roll is first folded, and then the two edges that are folded and adhered to each other are sealed to form a tubular structure. The bubble film roll with the tubular structure is then sealed and cut along the width direction by a port sealing and cutting device to obtain a bubble film packaging bag with a small end opening, making the bubble film packaging bag simple to manufacture.

[0007] Optionally, the folding and sealing device includes a frame, a raw material roller, a folding mechanism, a first ultrasonic roller pressing and welding machine and a winding roller, the folding mechanism and the first ultrasonic roller pressing and welding machine are arranged on the frame, the raw material roller is rotatably arranged on a side of the folding mechanism away from the first ultrasonic roller pressing and welding machine, the winding roller is rotatably arranged on a side of the first ultrasonic roller pressing and welding machine away from the folding mechanism, and the folding mechanism includes a tripod, two flattening rollers and a plurality of finishing rollers;

[0008] Two flattening rollers are rotatably connected to the frame, and the gap between the two flattening rollers is for the air bubble film coil to pass through after being folded. One of the triangular tips of the tripod is inclined downward and toward the gap between the two flattening rollers; a plurality of the sorting rollers are arranged close to the first ultrasonic roller pressing and welding machine, and the first ultrasonic roller pressing and welding machine is arranged on the frame. After the air bubble film coil is folded, it enters the first ultrasonic roller pressing and welding machine for edge sealing.

[0009] By adopting the above technical solution, during production, the bubble film coil is first processed into a cylindrical structure, the bubble film coil is rolled on the raw material roller, the bubble film coil is laid on the tripod, and extends toward the tip of the triangle inclined downward, and then folded on two flattening rollers, and after folding, it is closely attached to several finishing rollers and conveyed to the first ultrasonic roller pressing welding machine for edge sealing to prevent the folded bubble film coil from loosening in the middle, and the cylindrical structure after edge sealing is rolled up on the winding roller. The present application enables the bubble film coil to be edge-sealed after folding to obtain a cylindrical structure, which is highly efficient and convenient for further processing of the port sealing and cutting device.

[0010] Optionally, a support rod is fixed on the frame, and two bubble film positioning pieces are fixed on the support rod. The bubble film roll slides through the gap between the two bubble film positioning pieces. The midpoints of the two bubble film positioning pieces are on the same plane as the downward-inclined triangular tip of the tripod and the gap between the two flattening rollers.

[0011] By adopting the above technical solution, the positioning piece makes it difficult for the air bubble film roll to move, so that the two edges of the air bubble film roll are aligned after folding, which is convenient for edge sealing. If the two edges of the air bubble film roll are misaligned after folding, it is easy to press only one side during edge sealing, resulting in edge sealing failure.

[0012] Optionally, the port sealing and cutting device includes a main frame, a loading roller, a unloading conveyor belt, a plurality of conveyor rollers arranged in pairs, a second ultrasonic roller pressing and welding machine and a cutting mechanism, the conveyor rollers arranged in pairs are rotatably arranged on the main frame, the conveyor rollers clamp the bubble film coil with folded edges for driving it to move, the second ultrasonic roller pressing and welding machine is used to seal the bubble film coil along the width direction, and the cutting mechanism is used to cut off one side of the sealing edge formed by the second ultrasonic roller pressing and welding machine; after the bubble film coil is cut, it falls onto the unloading conveyor belt and is transported to a designated area.

[0013] By adopting the above technical scheme, during production, the bubble film coil processed by the folding and sealing device and folded and sealed is wrapped on the feeding roller, and a plurality of groups of conveying rollers arranged in pairs clamp the bubble film coil with folded and sealed edges to drive it to move, and then it is sealed by the second ultrasonic roller pressing and welding machine, and the cutting mechanism is cut on one side of the split edge to obtain a bubble film packaging bag with a small opening, so that the production of the bubble film packaging bag is simple and the production efficiency is high. And the shell of the port sealing and cutting device is obtained by modifying the equipment for producing large-opening packaging bags. The large-opening packaging bag connects the folding and sealing device and the port sealing and cutting device into a production line, without the need to use a winding roller and a raw material roller. After the bubble film coil is folded, it is directly transported by the conveying rollers arranged in pairs, and then two ultrasonic roller pressing and welding machines are used to seal the bubble film coil along the width direction to form two sealing lines, and then the two sealing lines are cut off, thereby producing a large-port packaging bag. The production equipment shell of the small-port bubble film packaging bag of the present application is obtained by improving the large-port packaging bag production equipment, without the need to purchase additional overall equipment, reducing production costs.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The small end opening allows the strip products to be directly transported after being loaded, which is convenient for packaging, good wrapping and protection, making it difficult for the product surface to be scratched;

[0016] 2. The air bubble film roll is folded first, and then the two edges that are folded and attached to each other are sealed to form a tubular structure.
