Description

Technical Field

[0001] The present invention belongs to the technical field of conveying and packaging equipment, and is a radial stretch film packaging machine for paper rolls with label implantation, which is used for implanting labels and radially stretching film packaging and conveying paper rolls. Background Art

[0002] In order to prevent moisture and facilitate transportation and storage, it is necessary to package stretch film for paper rolls that are temporarily not processed or sold outside after coming off the rewinder. And data is required for the storage and warehousing or external sales of paper rolls. In the prior art, a robot labeling device or manual labeling is usually set at the previous station before film wrapping, and the label is directly pasted onto the paper roll with glue or self-adhesive. Manual labeling has a high labor intensity and low production efficiency, and the cost of robot labeling and maintenance is high. Whether it is manual labeling or robot labeling, glue or self-adhesive is required, which damages the outermost layer of the paper roll, resulting in a section of the outermost layer of the paper roll that cannot be directly processed and utilized. Summary of the Invention

[0003] The present invention aims to provide a radial stretch film packaging machine with label implantation, which can simultaneously implant labels and radially stretch film package paper rolls, and can meet paper rolls of different diameters and widths. Label implantation does not require glue, and can be implanted at any specified position in the width direction of the paper roll. Moreover, label implantation and film wrapping are carried out simultaneously with time overlap. Therefore, label implantation does not affect the film wrapping time and has a fast beat. The entire equipment is fully automatic, with high production efficiency, no pollution or damage to the paper, and low cost.

[0004] The technical solution of the present invention:

[0005] A radial stretch film packaging machine with label implantation includes a label printing and turning plate component, a moving rack, an upper film component, a base component, a film feeding component, a label box component, a glue spraying component, a film pasting component, a film cutting component, and an on-line driving device.

[0006] The described label printing and flap component includes a chute, a flipping main shaft, a flipping drive motor, a label printing and flap component frame, a main flap component, a printer, and a flap pneumatic control system. The label printing and flap component frame is fixed on the ground base plate. The chute, the flipping main shaft, the flipping drive motor, the printer, and the flap pneumatic control system are fixedly installed on the label printing and flap component frame. The printer can directly print label paper. The main flap component is installed on the flipping main shaft, and the upper port of the main flap component faces the printer outlet. The labels printed by the printer can directly fall into the main flap component. The back of the main flap component is equipped with a vacuum system. Under the control of the pneumatic control system, the labels falling into the main flap component can be adsorbed. When the main flap component rotates around the flipping main shaft, the labels do not detach from the main flap component. When the main flap component flips to close with the chute, under the control of the pneumatic control system, the vacuum adsorption is released, and the labels complete flipping and fall into the chute. Under the action of gravity, the labels slide down the chute to the next working station.

[0007] The described moving frame is fixedly installed on the linear guide of the base component and moves back and forth along the conveying line direction under the drive of the synchronous belt. The upper film component, the film feeding component, the label box component, the glue spraying component, the film pasting component, and the film cutting component are all installed on the moving frame and can move back and forth along the conveying line direction together.

[0008] The described upper film component includes an upper film drive motor, swing arms, an upper film drive shaft, a film roll fixing component, and a film roll. The upper film drive motor and the upper film drive shaft are installed on the moving frame. The swing arms on both sides are installed on the upper film drive shaft, and the film roll fixing component is installed on the swing arms. When upper film is required, under the drive of the motor, the film roll fixing component swings around the upper film drive shaft together with the swing arms by an angle until the axis of the film roll fixing component is concentric with the axis of the film roll placed on the ground. At this time, start the cylinder of the film roll fixing component, insert the film roll fixing components on both sides into the paper shaft of the film roll simultaneously, and then start the upper film drive motor to lift the film roll off the ground and stand it up. At this time, the film roll can rotate around the film roll fixing component. This working station is the preparatory work for film wrapping.

[0009] The described base component includes a driven pulley, a synchronous belt, a linear guide, a driving pulley, and a drive motor. The synchronous belt is of a split type in the middle, and both ends of the synchronous belt are installed on the moving frame and are used to drive the moving frame to move back and forth in a cycle.

[0010] The described film feeding component includes a cylinder, a film feeding roller swing arm, a driven film feeding roller, a driving film feeding roller, and a film feeding drive motor. The cylinder, the film feeding roller swing arm, the driven film feeding roller, the driving film feeding roller, and the film feeding drive motor are installed on the moving rack. The cylinder drives the driven film feeding roller to swing down by an angle, leaving a certain gap between the driven film feeding roller and the driving film feeding roller. The stretch film passes through this gap. At this time, the cylinder is started again to make the driven film feeding roller press tightly against the driving film feeding roller. Driven by the film feeding motor, the two tightly pressed driven film feeding roller and the driving film feeding roller drive the stretch film to move in one direction. This station is for film wrapping.

[0011] The described label box component includes a label box, a cylinder, and a movable cover plate. The label box component is installed on the moving rack. The inlet of the label box is docked with the outlet of the chute. The outlet of the label box is above the stretch film. The label box is used to store labels. The movable cover plate is installed at the outlet of the label box. Driven by the cylinder, the movable cover plate can rotate around an axis by an angle. The movable cover plate is used to control the opening and closing of the outlet of the label box, thereby controlling the implantation time and position of the labels. When the label box is aligned with the chute, the labels slide into the label box under the action of gravity. At this time, the movable cover plate is in the closed state. When the moving rack runs to the position where the labels need to be implanted, the movable cover plate is opened, and the labels slide from the label box onto the moving stretch film, thus completing the implantation. This station is for label implantation during the film wrapping process.

[0012] The described glue spraying component includes a glue machine and a nozzle component. When the paper roll is about to complete film wrapping, the glue spraying component sprays a little glue on the stretch film to fix and paste the tail film. This station is when the film wrapping is almost completed.

[0013] The described film pasting component includes a film pasting component rack, a linear guide rail, a film pressing component, and a film pasting roller. The slider of the linear guide rail is installed on the moving rack. The film pressing component and the film pasting roller are installed on the film pasting roller component rack; the film pressing component can move up and down driven by a cylinder. Lower limit: The film pressing component presses tightly against the upper surface of the film pasting component rack. Upper limit: There is a certain gap between the film pressing component and the upper surface of the film pasting component rack. The film pasting roller is a static roller with rubber on its surface; the stretch film falls on the upper surface of the film pasting component rack. The stretch film passes through the gap between the film pasting component rack and the film pressing component. The stretch film covers the film pasting roller and hangs down to the center line of the film pasting roller, being in a semi-wrapped state; when film pasting is required, the film pressing component is driven by the cylinder to press the stretch film tightly against the surface of the film pasting component rack. The stretch film moves along with the film pasting component rack towards the paper roll direction until the film pasting roller presses the stretch film tightly against the paper roll to complete film pasting. This station is for initial film wrapping.

[0014] The described film cutting component includes a cylinder, a pedestal bearing, a film cutting frame, and a heating wire. The cylinder and the pedestal bearing are fixed on the moving frame. The film cutting frame is installed in the pedestal bearing. One end of the cylinder is connected to the film cutting frame. The heating wire is installed on the film cutting frame and is equipped with a control box, which can quickly heat up to more than 200 degrees. When contacting the stretch film, it can instantly cut the stretch film. When the paper roll is completely wrapped, the cylinder starts, and the film cutting frame drives the heating wire to swing by an angle, and the heating wire touches the stretch film to complete film cutting.

[0015] The described on-line driving device includes a driving roller component and a conveying component. The on-line driving device uses the lifting of the driving roller component or the lifting of the conveying component, and the lifting of the driving roller component or the lifting of the conveying component adopts pneumatic or hydraulic or electric lifting.

[0016] Advantages of the present invention: It can achieve label implantation and radial stretch film packaging for the paper roll simultaneously, saving time, cost, and space, and can meet paper rolls of different diameters and widths, with a wide application range. Label implantation does not require glue and is pollution-free. It can implant at any specified position in the width direction of the paper roll, and label implantation and film wrapping are carried out simultaneously with time overlap. Therefore, label implantation does not affect the film wrapping time and has a fast beat. The whole equipment is fully automatic, with high production efficiency, no pollution or damage to the paper, and low cost. Description of the Drawings

The slider of the linear guide rail 39 is installed on the moving rack 7. The film pressing component 40 and the film pasting roller 41 are installed on the film pasting roller component rack 38. The film pressing component 40 can move up and down driven by a cylinder. Lower limit: The film pressing component 40 is closely attached to the upper surface of the film pasting component rack 38. Upper limit: There is a gap of about 30 mm between the film pressing component 40 and the upper surface of the film pasting component rack 38. The film pasting roller 41 is a static roller with rubber on its surface. The stretch film falls on the upper surface of the film pasting component rack 38. The stretch film passes through the gap between the film pasting component rack 38 and the film pressing component 40. The stretch film covers the film pasting roller 41 and hangs down to the center line of the film pasting roller 41, being in a semi - wrapped state. When film pasting is required, the film pressing component 40, driven by the cylinder, presses the stretch film tightly onto the surface of the film pasting component rack 38. The stretch film runs towards the paper roll along with the film pasting component rack 38 until the film pasting roller 41 presses the stretch film tightly against the paper roll to complete the film pasting. This station is when the initial film wrapping is carried out.

[0037] Figure 9As shown in the figure: The film cutting component 9 includes a cylinder 42, a pedestal bearing 43, a film cutting frame 44, and a heating wire 45.

[0038] Figure 10 As shown in the figure: The on-line driving device 10 includes a driving roller component 46 and a conveying component 47. The driving roller component 46 is used for the rotation of the paper roll during the packaging process, and the conveying component 47 is used for the conveying of the paper roll before and after packaging. Before packaging, the conveying component 47 rises. At this time, the working surface of the conveying component 47 and the working surface of the docking conveyor are on the same plane, and the lowest surface of the paper roll is higher than the driving roller component 46. The paper roll is conveyed to the central position of the on-line driving device 10, and the conveying component descends. The paper roll falls into the driving roller component 46. When the film contacts the paper roll, the driving roller component 46 rotates and starts wrapping. The lifting of the conveying component 47 can be pneumatic, hydraulic, or electric. The on-line driving device 10 can be the lifting of the driving roller component 46 or the lifting of the conveying component 47. It is configured comprehensively according to the beat, cost, and customer requirements.

[0039] The working process of the present invention is as follows: After the paper roll comes down from the rewinder, it is conveyed to the conveying component 47. The paper roll is conveyed to the central position of the on-line driving device 10, and the conveying component 47 descends. While the paper roll is being conveyed, the label printing and turning plate component 1 simultaneously performs label printing and conveying. The label slides into the label box 33 of the label box component 5 through the chute 11 and waits to be implanted. The film laminating component 8 is driven by a cylinder to drive the stretch film to run towards the paper roll. When the film laminating roller 41 presses the stretch film against the paper roll, the film pressing component 40 moves away from the film laminating component frame 38 under the drive of the cylinder, releasing the stretch film from the pressed state. The film feeding component 4 starts to feed the film under the drive of the film feeding drive motor 32. At the same time, the driving roller component 46 of the on-line driving device 10 starts to rotate, and the driving motor 26 of the base component 3 runs to drive the moving frame 7 etc. to move back and forth. The three actions cooperate with each other to start film wrapping, and the film laminating component 8 resets. When the film wrapping reaches the position for label implantation, the movable cover plate 35 of the label box component 5 opens, and the label slides from the label box 33 onto the running stretch film. The stretch film and the label are wrapped around the side of the paper roll together to complete label implantation. The driving roller component 46 and the film feeding component 4 start to decelerate. The film laminating component 8 is driven by a cylinder to drive the stretch film to run towards the paper roll, and the nozzle component 37 of the glue spraying component 6 starts to spray glue. After about 2 seconds, the film laminating component frame 38 of the film laminating component 8 retracts, and the cylinders of the film pressing component 40 and the film cutting component 9 run simultaneously to complete film cutting and film pressing, and then reset. The driving roller component 46 and the film feeding component 4 stop running. The conveying component 47 rises to convey the paper roll to the next working station and start packaging the next paper roll.
