[0002] Packaging bags refer to bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Currently, during film edge welding, the machine needs to be stopped for unwinding, labeling, and rewinding, resulting in discontinuous film edge welding operations, low efficiency, and increased material waste due to downtime. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a non-stop roll changing, labeling and edge melting integrated machine that, when unwinding, rewinding, labeling and changing rolls, can achieve non-stop film edge melting, improve work efficiency and reduce product material waste.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a non-stop roll changing, labeling, and edge-sealing integrated machine, including a frame, on which an unwinding unit, a roller cutter mechanism, a labeling mechanism, a folding mechanism, an edge-sealing mechanism, and a winding unit are arranged sequentially along the film moving direction. The film unwound by the unwinding unit is sequentially drawn to the roller cutter mechanism, the labeling mechanism, the folding mechanism, and the edge-sealing mechanism. The roller cutter mechanism punches holes in the film, the labeling mechanism applies labels to the film, the folding mechanism folds the film in half, and the edge-sealing mechanism melts the folded film into a cylindrical film. Then, the winding unit winds up the cylindrical film. A double-layer material storage mechanism is provided between the labeling mechanism and the folding mechanism to store a large amount of material in the labeled film. A single-layer material storage mechanism is provided on the outlet side of the edge-sealing mechanism to store material in the cylindrical film after edge sealing.

[0005] The double-layer storage mechanism includes a first storage unit and a second storage unit. The first storage unit includes a first upper storage roller group and a first lower storage roller group arranged in parallel. The second storage unit includes a second upper storage roller group and a second lower storage roller group arranged in parallel. The first and second upper storage roller groups are mounted on a double-layer storage fixed frame, and the first and second lower storage roller groups are mounted on a double-layer storage movable frame. The tension control device drives the double-layer storage movable frame to move up and down, causing the first and second lower storage roller groups to move away from the first and second upper storage roller groups, thereby tensioning the film.

[0006] The unwinding unit includes multiple unwinding drums arranged in parallel vertically. An inclined receiving platform is provided above the unwinding drums. After the unwinding drums alternately unwind the film, it is conveyed backward through the receiving platform.

[0007] The winding unit includes multiple winding drums arranged in parallel vertically, which alternately wind up the film.

[0008] The frame is equipped with an unwinding correction photoelectric sensor and a rewind correction photoelectric sensor.

[0009] The tension control device includes a rotating shaft arranged vertically and horizontally, with sprockets at both ends of the rotating shaft. A chain is fitted between the two sprockets on the same side, and the chain meshes with the two sprockets. Two chain connecting blocks are arranged vertically and horizontally on the outer side of the double-layer material storage moving frame. The chain passes through the chain connecting blocks and is fixedly connected to the chain connecting blocks. A torque servo motor is installed at the top of the frame. The output shaft of the torque servo motor is fixedly connected to the rotating shaft on the upper side. The torque servo motor drives the rotating shaft to rotate, which in turn drives the sprockets to rotate, causing the chain to move along the sprockets and drive the double-layer material storage moving frame to descend, so that the first and second lower material storage roller groups move away from the first and second upper material storage roller groups on the upper side.

[0010] The first storage upper roller group includes multiple evenly spaced first storage upper rollers, and the first storage lower roller group includes multiple evenly spaced first storage lower rollers. The first storage upper rollers and the first storage lower rollers are staggered. The second storage upper roller group includes multiple evenly spaced second storage upper rollers, and the second storage lower roller group includes multiple evenly spaced second storage lower rollers. The second storage upper rollers and the second storage lower rollers are staggered. The upper first storage upper rollers and the second storage upper rollers correspond to each other, and the lower first storage lower rollers and the second storage lower rollers correspond to each other. The labeled film is first sequentially wound onto the first storage lower rollers and the second storage upper rollers, and then wrapped around the first storage upper rollers and the second storage lower rollers to achieve double-layer storage.

[0011] The single-layer storage mechanism includes a third upper storage roller group and a third lower storage roller group arranged in parallel. The third upper storage roller group includes multiple third upper storage rollers arranged at even intervals, and the multiple third upper storage rollers are disposed on a single-layer storage fixed frame. The third lower storage roller group includes multiple third lower storage rollers arranged at even intervals, and the multiple third lower storage rollers are disposed on a single-layer storage movable frame. The third upper storage rollers and the third lower storage rollers are arranged alternately.

[0012] The roller cutter mechanism is equipped with a roller cutter correction photoelectric sensor, the labeling mechanism is equipped with a labeling correction photoelectric sensor, and the labeling mechanism outlet is equipped with a vision camera.

[0013] Compared with the prior art, the advantages of this utility model are as follows: a non-stop roll changing, labeling, and edge-sealing integrated machine is provided, with a double-layer material storage mechanism between the labeling mechanism and the folding mechanism, which stores a large amount of material in the film after labeling; a single-layer material storage mechanism is provided on the outlet side of the edge-sealing mechanism, which stores material in the rolled film after edge sealing. The setting of the double-layer material storage mechanism and the single-layer material storage mechanism enables the edge-sealing mechanism to operate without stopping when changing rolls in the unwinding unit, the rewinding unit, and the labeling mechanism, thereby improving work efficiency and reducing product material waste.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1As shown in this embodiment, a non-stop roll changing, labeling, and edge-sealing integrated machine includes a frame 1. Along the film movement direction, the frame 1 is sequentially provided with an unwinding unit, a roller cutter mechanism 8, a labeling mechanism 9, a folding mechanism 18, an edge-sealing mechanism 19, and a winding unit. The film unwound by the unwinding unit is sequentially drawn to the roller cutter mechanism 8, the labeling mechanism 9, the folding mechanism 18, and the edge-sealing mechanism 19. The roller cutter mechanism 8 punches holes in the film, the labeling mechanism 9 applies labels to the film, the folding mechanism 18 folds the film in half, and the edge-sealing mechanism 19 melts the folded film into a cylindrical film. Then, the winding unit winds up the cylindrical film. A double-layer material storage mechanism is provided between the labeling mechanism 9 and the folding mechanism 18. The double-layer material storage mechanism stores a large amount of material in the film after labeling. A single-layer material storage mechanism is provided on the outlet side of the edge-melting mechanism 19. The single-layer material storage mechanism stores material in the roll film after edge melting. The setting of the double-layer material storage mechanism and the single-layer material storage mechanism enables the edge-melting mechanism to operate without stopping when changing rolls in the unwinding unit, the rewinding unit and the labeling mechanism, thereby reducing the waste of product materials.

[0019] The unwinding unit includes two unwinding drums arranged parallel to each other: unwinding drum A 2 and unwinding drum B 3. An inclined receiving platform 4 is provided above unwinding drum A 2. After unwinding drum B 3 alternately unwinds the film, it is conveyed to the roller mechanism 8 via the receiving platform 4, conveying roller group 5, and traction roller 7. When one unwinding drum unwinds the film, the other unwinding drum is pre-loaded, which is convenient and quick.

[0020] The winding unit includes two winding drums arranged parallel to each other: winding drum A 23 and winding drum B 24. The two winding drums alternately wind up the film. While one winding drum is winding up the film, the other winding drum is pre-loaded, which is convenient and quick.

[0021] The frame is equipped with an unwinding correction photoelectric sensor 6 and a rewinding correction photoelectric sensor 22. The unwinding correction sensor 6 detects the position of the unwound film, and the rewinding correction photoelectric sensor 22 detects the position of the roll film, thereby correcting the positions of the film and the roll film.

[0022] like Figure 2As shown, the double-layer storage mechanism includes a first storage unit and a second storage unit. The first storage unit includes a first storage upper roller group and a first storage lower roller group arranged vertically in parallel. The first storage upper roller group includes multiple first storage upper rollers 13 arranged at uniform intervals, and the first storage lower roller group includes multiple first storage lower rollers 12 arranged at uniform intervals. The first storage upper rollers 13 and the first storage lower rollers 12 are staggered. The second storage unit includes a second storage upper roller group and a second storage lower roller group arranged vertically in parallel. The second storage upper roller group includes multiple second storage upper rollers 17 arranged at uniform intervals, and the second storage lower roller group includes multiple second storage lower rollers 16 arranged at uniform intervals. The second storage upper rollers 17 and the second storage lower rollers 16 are staggered. The upper storage roller 13 and the upper storage roller 17 on the upper side correspond to each other and are fixed at both ends to the double-layer storage fixing frame 31. The lower storage roller 12 and the lower storage roller 16 on the lower side correspond to each other and are fixed to the double-layer storage moving frame 29. The labeled film is first wrapped sequentially on the lower storage roller 12 and the upper storage roller 17, and then wrapped around the upper storage roller 13 and the lower storage roller 16 to achieve double-layer storage. The frame is provided with a rotating shaft 25 arranged vertically and horizontally. Sprockets 15 are respectively provided at both ends of the rotating shaft 25. A chain 26 is respectively sleeved between the two sprockets 15 on the same side, and the chain 26 meshes with the two sprockets 15. Two chain connecting blocks 30, spaced vertically, are respectively provided on the outer side of the double-layer material storage moving frame 29. Chains 26 pass through the chain connecting blocks 30 and are fixedly connected to the chain connecting blocks 30 via chain retainers, thus the chains 26 are fixedly connected to the double-layer material storage moving frame 29. A torque servo motor 14 is provided at the top of the frame, and the output shaft of the torque servo motor 14 is fixedly connected to the upper rotating shaft 25. The torque servo motor 14 drives the rotating shaft 25 to rotate, which in turn drives the sprocket 15 to rotate, causing the chains 26 to move along the sprocket. This causes the double-layer material storage moving frame to descend, moving the lower first and second material storage roller groups away from the upper first and second material storage roller groups, thereby tensioning the film.

[0023] The frame 1 is symmetrically equipped with vertically arranged double-layer storage guide rods 27, and the outer side of the double-layer storage moving frame is symmetrically equipped with double-layer storage guide blocks 28. The double-layer storage guide rods 27 pass through the double-layer storage guide blocks 28. When the double-layer storage moving frame moves up and down, the double-layer storage guide blocks move along the double-layer storage guide rods to guide the movement, prevent the double-layer storage moving frame from shaking, and achieve stable movement of the double-layer storage moving frame.

[0024] The single-layer storage mechanism includes a third storage upper roller group and a third storage lower roller group arranged in parallel. The third storage lower roller group includes multiple third storage lower rollers 20 arranged at even intervals, which are mounted on the single-layer storage moving frame. The third storage upper roller group includes multiple third storage upper rollers 21 arranged at even intervals, which are mounted on the single-layer storage fixed frame. The third storage upper rollers 21 and the third storage lower rollers 20 are arranged alternately. A single-layer storage slider is provided on the outer side of the third storage moving frame, and a single-layer storage guide rod is vertically provided on the frame, with the single-layer storage guide rod passing through the single-layer storage slider. Due to changes in the film tension, the third storage lower roller group moves closer to or further away from the third storage upper roller group. During the movement of the third storage lower roller group, the single-layer storage moving frame and the single-layer storage slider move along the single-layer storage guide rod.

[0025] A roller cutter correction photoelectric sensor is installed at the roller cutter mechanism, and a labeling correction photoelectric sensor 10 is installed at the labeling mechanism. The roller cutter correction photoelectric sensor is connected to the roller cutter correction servo motor, and the labeling correction photoelectric sensor 10 is connected to the labeling correction servo motor. The roller cutter correction photoelectric sensor and the labeling correction photoelectric sensor 10 track the left and right positions of the film in real time, thereby controlling the roller cutter correction servo motor and the labeling correction servo motor, making the opening and labeling positions more accurate.

[0026] A vision camera 11 is installed at the exit of the labeling mechanism. The vision camera 11 can detect whether there is any deviation in the position of the label on the film at any time, and feed it back to the control system for automatic adjustment, thereby improving the labeling position accuracy.

[0027] This application features a double-layer storage mechanism between the labeling mechanism and the folding mechanism, which stores a large amount of material in the labeled film. A single-layer storage mechanism is located on the outlet side of the edge-melting mechanism, which stores material in the melted film roll. The combination of the double-layer and single-layer storage mechanisms allows the edge-melting mechanism to operate without stopping when changing rolls in the unwinding, rewinding, and labeling mechanisms, thus improving operational efficiency and reducing material waste.

[0028] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
