Abstract
Description
Technical Field
[0001] This application relates to the technical field of film packaging, and in particular to an automatic labeling multilayer laminating machine. Background Technology
[0002] Plastic film is a type of film made from polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins. It is used for packaging in the medical, food, and chemical industries, and as a coating layer. Plastic film laminating machines are widely used in food packaging, pharmaceutical packaging, building materials, and agricultural coverings. In food packaging, plastic film laminating machines can produce composite materials with certain moisture-proof, oxidation-proof, and minor external force-resistant properties, ensuring the freshness and safety of food. In some medical packaging films, recording is required during use. Typically, operators manually affix labels to a specific location on the film after sealing the item. Some manufacturers also have labels manually affixed after film production, with subsequent recording done by writing on the labels.
[0003] Regarding the aforementioned technologies, the inventors believe that conventional labeling methods require transferring the composite film and label paper to a dedicated labeling device after production, resulting in low overall efficiency of film packaging and increased production costs. Utility Model Content
[0004] In order to improve the processing efficiency of composite film labeling and reduce production costs, this application provides an automatic multi-layer labeling laminating machine.
[0005] The automatic labeling multilayer laminating machine provided in this application adopts the following technical solution:
[0006] An automatic labeling multilayer laminating machine includes a support frame, a support base plate, a laminating assembly, and a labeling assembly. The support frame is vertically mounted on the top surface of the support base plate. The laminating assembly includes a first unwinding roller, a second unwinding roller, a first support, a first laminating roller, and a second laminating roller. The first and second unwinding rollers are both located on one side of the support frame. A first laminating film is wound on the first unwinding roller, and a second laminating film is wound on the second unwinding roller. The first support is located on the top surface of the support base plate. The first and second laminating rollers are horizontally and parallel to each other on the first support. The first and second laminating films pass between the first and second laminating rollers to form a composite film. The composite film body includes a label unwinding roller, a waste collection roller, a separation plate, a second support, a first adhesive roller, and a second adhesive roller. The label unwinding roller, waste collection roller, and separation plate are all disposed on one side of the supporting vertical frame. A release paper tape is wound on the label unwinding roller, and the other end of the release paper tape is wound on the waste collection roller. Several label bodies are adhered to the release paper tape. The first adhesive roller and the second adhesive roller are both parallel and horizontally disposed on the second support. One side of the separation plate extends between the first adhesive roller and the second adhesive roller. The release paper bag passes around the separation plate near the edge of the second support. The composite film body passes between the first adhesive roller and the second adhesive roller.
[0007] By adopting the above technical solution, the first unwinding roller and the second unwinding roller unwind the first composite film and the second composite film. The first composite film and the second composite film pass together through the first composite roller and the second composite roller, which press the first composite film and the second composite film together, thus achieving film lamination. After lamination, the composite film body passes between the first adhesive roller and the second adhesive roller. When the release paper tape passes through the separation plate, the label body separates from the release paper tape and adheres to the film. The first adhesive roller and the second adhesive roller stably adhere the label to the composite film body, realizing automatic labeling. Through the cooperation of the support frame, support base plate, lamination component, and labeling component, film lamination and automated labeling are achieved, which improves the processing efficiency of composite film labeling and reduces production costs.
[0008] Optionally, the first support includes two parallel first vertical plates, with the first composite roller and the second composite roller rotatably disposed between the two first vertical plates. A first sliding block is rotatably disposed at both ends of the second composite roller. The two first sliding blocks correspond one-to-one with the two first vertical plates and are vertically slidably connected. A first elastic element is disposed between the first vertical plates and the first sliding blocks. The second composite roller abuts against the first composite roller under the action of the first elastic element. The second support includes two parallel second vertical plates, with the first adhesive roller and the second adhesive roller rotatably disposed between the two second vertical plates. A second sliding block is rotatably disposed at both ends of the second adhesive roller. The two second sliding blocks correspond one-to-one with the two second vertical plates and are vertically slidably connected. A second elastic element is disposed between the second vertical plates and the second sliding blocks. The second adhesive roller abuts against the first adhesive roller under the action of the second elastic element.
[0009] By adopting the above technical solution, the first and second compression springs enable the device to be suitable for laminating and labeling films of different thicknesses.
[0010] Optionally, the support frame is provided with a first tension roller and a second tension roller. The first tension roller is disposed between the first unwinding roller and the first support, and the second tension roller is disposed between the second unwinding roller and the first support. The first composite film passes around the first tension roller and abuts against it, and the second composite film passes around the second tension roller and abuts against it.
[0011] By adopting the above technical solution, the arrangement of the first tensioning roller and the second tensioning roller ensures that the first composite film and the second composite film can always be kept in a taut state, which helps to improve the production quality of the composite film body.
[0012] Optionally, the separating plate is slidably connected to the supporting vertical frame. The supporting vertical frame is provided with a driving component for driving the separating plate to move along a direction perpendicular to the plane of the supporting vertical frame. The separating plate is rotatably provided with a separating roller near the edge of the second bracket. Each end of the separating roller is provided with a limiting end plate, and the distance between the two limiting end plates is equal to the width of the release paper tape.
[0013] By adopting the above technical solutions, the setting of the separation roller reduces the possibility of damage to the label body when it separates from the release paper tape, and the setting of the limiting end plate realizes the limiting of the release paper tape, avoiding the release paper tape from sliding relative to the separation plate during the pasting process.
[0014] Optionally, the driving component includes a displacement screw and a displacement guide rod. The displacement screw is vertically threaded onto the support frame, and the displacement guide rod passes vertically through the support frame and is slidably connected to it. One end of the displacement guide rod is connected to the separation plate, and one end of the displacement screw is rotatably connected to the separation plate.
[0015] By adopting the above technical solution, the labeling position can be adjusted by rotating the displacement screw and moving the separation plate closer to or further away from the support frame under the combined action of the displacement screw and the displacement guide rod, in order to meet the needs of different labeling positions.
[0016] Optionally, the displacement guide rod is provided with adjustment scale lines along its length.
[0017] By adopting the above technical solution, adjusting the scale line settings helps operators to accurately adjust the labeling position.
[0018] Optionally, a first sliding groove is formed along the vertical direction on the first vertical plate, a first sliding block is slidably disposed in the first sliding groove, the first sliding block is rotatably connected to the corresponding end of the second composite roller, an adjusting slider is slidably disposed in the first sliding groove, a first elastic element is disposed between the adjusting slider and the first sliding block, and an adjusting element for driving the adjusting slider to move is provided on the first vertical plate.
[0019] By adopting the above technical solution, the position of the adjusting slider in the first sliding groove can be adjusted by the driving component to meet different pressing strength requirements. This achieves the adjustment of the pressing strength of the first and second composite rollers.
[0020] Optionally, an abutment roller is vertically arranged on the support frame, the abutment roller is disposed between the first bracket and the second bracket, and the height of the abutment roller is lower than the height of the first composite roller.
[0021] By adopting the above technical solution, the composite roller body after lamination is strengthened by the abutting action of the abutting roller, which helps to improve the quality of film lamination.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. Through the cooperation of the support frame, support base plate, composite components and labeling components, the film lamination and automated labeling are realized, which can improve the processing efficiency of composite film labeling and reduce production costs;
[0024] 2. The separation roller reduces the possibility of damage to the label body when it separates from the release paper tape, and the limiting end plate limits the release paper tape, preventing the release paper tape from sliding relative to the separation plate during the pasting process;
[0025] 3. Adjusting the scale lines helps operators make precise adjustments to the labeling position. Attached Figure Description

The separating plate 66 is inclined and one side extends between the first adhesive roller 71 and the second adhesive roller 72. An installation groove 661 is provided on the side of the separating plate 66 near the first adhesive roller 71 and the second adhesive roller 72. The separating roller 662 is rotatably disposed in the installation groove 661. The separating roller 662 is parallel to the first adhesive roller 71. A limiting end plate 663 is coaxially disposed at both ends of the separating roller 662. The diameter of the limiting end plate 663 is larger than the diameter of the separating roller 662.
[0039] Reference Figure 1-3 The displacement screw 67 and displacement guide rod 68 are both arranged parallel to each other on the side of the separation plate 66 near the support frame 2.

The composite film body 16 passes between the first adhesive roller 71 and the second adhesive roller 72. The label unwinding motor 10 starts, driving the label unwinding roller 61 to rotate and unwind the release paper tape 62. The release paper tape 62 sequentially passes through several guide rollers 65 and separating rollers 662. The limiting end plate 663 limits the release paper tape 62, preventing the label position from moving during the label application process. When it is necessary to adjust the position of the label body 63 on the composite film body 16, the displacement screw 67 is rotated. Under the drive of the displacement screw 67 and the limiting guidance of the displacement guide rod 68, the separating plate 66 moves towards or away from the support frame 2, thus adjusting the label application position.
[0043] Reference Figure 3 , Figure 2 and Figure 4 Under the action of the separating roller 662, the label body 63 separates from the release paper tape 62 and adheres to the composite film body 16. The first adhesive roller 71 and the second adhesive roller 72 press the composite film body 16 and the label body 63 tightly together, achieving precise label adhesion. The take-up motor 15 drives the take-up roller 14 to rotate and rewind the labeled composite film body 16.
[0044] The implementation principle of an automatic labeling multilayer laminating machine in this embodiment is as follows: During the lamination and labeling operation of the film, the first composite film 42 and the second composite film 45 pass together between the first composite roller 8 and the second composite roller 9 to form a composite film body 16. The release paper tape 62 passes sequentially through several guide rollers 65 and separation rollers 662, and the label body 63 separates from the release paper tape 62 and is adhered to the composite film body 16. The first adhesive roller 71 and the second adhesive roller 72 tightly press the composite film body 16 and the label body 63 together, achieving precise label adhesion. The take-up motor 15 drives the take-up roller 14 to rotate and rewind the labeled composite film body 16.
