Description

Technical Field

[0001] The utility model relates to the technical field of laminating equipment, in particular to a label laminating machine and the laminated label paper produced therefrom. Background Art

[0002] Existing aluminum veneer production typically involves a series of processes, including cutting, bending, cleaning, and painting. Cutting typically involves shearing, engraving, and laser cutting, creating multiple blanks of varying specifications from a single standard aluminum sheet. To facilitate subsequent processing, each blank requires labeling, assigning production information such as serial number, number, color, area, project name, and batch number.

[0003] Since aluminum veneers need to undergo a spraying process during production, the label will be covered by the spray and cannot be identified. Therefore, a protective film needs to be affixed to the label before spraying begins, and the protective film should be torn off after spraying is completed to protect the integrity of the label.

[0004] Although some factories still cover labels by manually applying film, most factories are gradually adopting laminated label paper to save labor costs. Their production equipment, such as the "Laminating and Cutting Device for Label Printers" with publication number CN219969223U, can produce laminated label paper with tear lines on the protective film and label paper at the same time, so that workers can directly stick labels on aluminum panels, saving time and effort.

[0005] However, with technological advancements, some factories have begun using automatic labeling machines. However, the laminated label paper produced by existing equipment has tear lines, making it difficult to separate the laminated surface from other laminated label paper when peeling off the release layer. This means that the laminated label paper produced by existing equipment is only suitable for manual labeling and cannot be used in automatic labeling machines. Utility Model Content

[0006] The utility model aims to provide a label laminating machine for producing laminated label paper suitable for an automatic labeling machine.

[0007] According to the first embodiment of the present invention, the label laminating machine includes:

[0008] A first unwinding mechanism, which is provided with a first unwinding roller for placing the label paper roll;

[0009] a second unwinding mechanism, which is provided with a second unwinding roller for placing the protective film roll;

[0010] a film pressing mechanism located downstream of the first unwinding mechanism and the second unwinding mechanism, the film pressing mechanism comprising an upper pressing roller and a lower pressing roller, with a film pressing space being provided between the upper pressing roller and the lower pressing roller;

[0011] a film cutting mechanism located downstream of the film pressing mechanism, the film cutting mechanism comprising a linear reciprocating device and a cutting portion, the linear reciprocating device driving the cutting portion to perform horizontal reciprocating movement along a direction orthogonal to the direction of conveying the label paper, the movement path of the cutting portion intersecting the movement path of the protective film;

[0012] an inductive sensor located downstream of the film cutting mechanism, the inductive sensor being provided with an inductive probe for identifying gaps, and the distance between the inductive sensor and the film cutting mechanism being adjustable;

[0013] a label winding mechanism, located downstream of the inductive sensor, the label winding mechanism being provided with a first winding roller driven by a power source;

[0014] The frame is provided with a mounting surface, and the first unwinding mechanism, the second unwinding mechanism, the film pressing mechanism, the film cutting mechanism, the inductive sensor and the label winding mechanism are all mounted on the mounting surface.

[0015] The label laminating machine according to the embodiment of the present invention has at least the following beneficial effects: during production, under the drive of the label winding mechanism, the first unwinding mechanism and the second unwinding mechanism respectively unwind the label paper and the protective film outward, and the two are subjected to the joint force of the upper pressing roller and the lower pressing roller when passing through the film pressing space, and are pressed against each other and formed into a laminated label paper together; then, when the laminated label paper passes through the film cutting mechanism, the label winding mechanism stops, and the linear reciprocating device drives the cutting part to move along the width direction of the laminated label paper; if the label paper roll is provided with a gap between two adjacent label papers, then the cutting part only needs to cut the protective film, After that, the label winding mechanism starts again, and when the induction sensor detects the gap between the laminated label paper, the above-mentioned slitting process is repeated. Finally, the slit laminated label paper is wound on the first winding roller. Since the distance between the induction sensor and the film cutting mechanism is adjustable, the utility model can produce laminated label papers of different sizes, and since there is no tear line between two adjacent laminated label papers, when the laminated label paper produced by this technology is used in an automatic labeling machine, its laminated surface layer can be smoothly separated from the laminated surface layer of other laminated label papers when peeling off the release layer, so as to meet the conditions for automatic labeling.

[0016] According to some embodiments of the present invention, the linear reciprocating device is connected to an up-and-down adjustment unit, and the linear reciprocating device is connected to the cutting part through the up-and-down adjustment unit to adjust the up-and-down position of the cutting part.

[0017] According to some embodiments of the present invention, the label paper includes a surface layer and a release layer. If the label paper roll does not have a gap between two adjacent label papers, the moving path of the cutting portion intersects with the moving path of the surface layer.

[0018] According to some embodiments of the present invention, in order to facilitate adjustment of the distance between the inductive sensor and the film cutting mechanism, the mounting surface is provided with a scale along the moving direction of the inductive sensor.

[0019] According to some embodiments of the present invention, the laminating mechanism further includes a laminating mounting frame, the lower laminating roller being rotatably connected to the laminating mounting frame, the laminating mounting frame being rotatably connected to a swing frame, and the upper laminating roller being rotatably connected to the swing frame. When the swing frame rotates around the laminating mounting frame, the relative position between the upper and lower laminating rollers changes, thereby adjusting the gap size in the laminating space. When the label paper or protective film is short of material, the upper laminating roller is opened to replenish the material.

[0020] According to some embodiments of the present invention, in order to limit the minimum gap of the film pressing space, the film pressing mounting frame is connected to a limiting unit on the moving path of the swing frame, and the limiting unit is provided with a position-adjustable limiting member.

[0021] According to some embodiments of the present invention, a plurality of tensioning mechanisms are further installed on the mounting surface to maintain the tension of the material during transportation.

[0022] According to some embodiments of the present invention, the mounting surface is provided with a pad below the cutting portion, the pad having air holes on its surface and an ion generator built into the pad. Since the protective film can adhere to contact objects when charged with static electricity, in order to eliminate the adverse effects of the coated label paper during use, it is necessary to remove the positive charge from the coated label paper.

[0023] According to some embodiments of the present invention, the first unwinding mechanism and / or the second unwinding mechanism is provided with a material shortage sensor to remind the user to refill the material.

[0024] The laminated label paper according to the second embodiment of the present invention is produced by the above-mentioned label laminating machine.

[0025] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0036] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] like Figures 1 to 4 As shown, the label laminating machine according to the first embodiment of the present invention includes a frame 100, a first unwinding mechanism 200, a second unwinding mechanism 300, a film pressing mechanism 400, a film cutting mechanism 500, an inductive sensor 600 and a label winding mechanism 700, wherein the upper surface of the frame 100 is provided with a mounting surface 110, and the mounting surface 110 is used to install the above-mentioned first unwinding mechanism 200, the second unwinding mechanism 300, the film pressing mechanism 400, the film cutting mechanism 500, the inductive sensor 600 and the label winding mechanism 700; the interior of the frame 100 is used to configure components such as circuit boards, power supplies, and control circuits; a control panel 120 is installed on the side of the frame 100 to control all actions of the label laminating machine. The material conveying direction is from unwinding to rewinding, that is, the first unwinding mechanism 200 and the second unwinding mechanism 300 are both located upstream of the label rewinding mechanism 700. Along the conveying direction, the label laminating machine is also sequentially provided with a film pressing mechanism 400, a film cutting mechanism 500, an induction sensor 600 and a label rewinding mechanism 700.

[0039] Exemplarily, the first unwinding mechanism 200 includes a first unwinding frame (not shown in the drawings) and a first unwinding roller 220. The first unwinding frame is fixedly connected to the mounting surface 110. The first unwinding frame is rotatably connected to the first unwinding roller 220. The first unwinding roller 220 is freely rotatable and is used to place the label paper roll 230. When the label paper of the label paper roll 230 is pulled out, the first unwinding roller 220 will rotate due to the action of the tension. The label paper roll 230 described herein has two structures. The first is that a gap is processed between each adjacent two label papers through a pre-process. The gap only appears on the surface layer of the label paper and does not appear on the release layer of the label paper, so that the surface layer of any label paper can be removed separately; the second is that no gap is processed between each adjacent two label papers, so that the surface layer of any label paper cannot be removed separately.

[0040] Exemplarily, the second unwinding mechanism 300 includes a second unwinding frame 310 and a second unwinding roller 320. The second unwinding frame 310 is fixedly connected to the mounting surface 110. The second unwinding frame 310 is located above the first unwinding frame. The second unwinding frame 310 is rotatably connected to the second unwinding roller 320. The second unwinding roller 320 is freely rotatable and is used to place the protective film roll 330. When the protective film of the protective film roll 330 is pulled out, the second unwinding roller 320 will rotate due to the action of the tension. The protective film roll 330 described herein has two structures. The first is without a backing paper, and the films are in direct contact with each other, such as a PET protective film; the second is with a backing paper, and the films are not in direct contact with each other, such as a PI protective film.

[0041] Furthermore, for the second type of protective film, since it has a base paper, a base paper rewinding mechanism 800 is also required to rewind the separated base paper. The base paper rewinding mechanism 800 includes a base paper rewinding roller 820, which is rotatably connected to the second unwinding frame 310 and is located between the second unwinding roller 320 and the first unwinding roller 220. The base paper rewinding roller 820 is driven by a base paper rewinding motor (not shown in the drawings) and is used to rewind the protective film base paper.

[0042] It should be noted that, for the first type of protective film, since it does not have a base paper, the base paper winding mechanism 800 does not need to be started during operation to save energy.

[0043] like Figure 5 and Figure 6As shown, exemplarily, the laminating mechanism 400 includes a laminating mounting frame 410, an upper pressing roller 420, and a lower pressing roller 430. The laminating mounting frame 410 is fixedly connected to the mounting surface 110. The laminating mounting frame 410 is rotatably connected to the upper pressing roller 420 and the lower pressing roller 430. The upper pressing roller 420 and the lower pressing roller 430 are both freely rotatable. The upper pressing roller 420 is located above the lower pressing roller 430. A laminating space 401 is provided between the upper pressing roller 420 and the lower pressing roller 430. The height of the laminating space 401 is not greater than the sum of the thicknesses of the label paper and the protective film. When the label paper and the protective film are conveyed through the laminating space 401, since the height of the laminating space 401 is not greater than the sum of the thicknesses of the label paper and the protective film, under the joint force of the upper pressing roller 420 and the lower pressing roller 430, the label paper and the protective film are pressed against each other, so that the protective film can be tightly attached to the surface of the label paper.

[0044] Furthermore, the lamination mounting frame 410 is rotatably connected to a swing frame 440 via a rotating shaft 441. The upper pressing roller 420 is rotatably connected to the swing frame 440. Since the swing frame 440 can rotate relative to the lamination mounting frame 410, the relative position between the upper pressing roller 420 and the lower pressing roller 430 can be adjusted, thereby adjusting the gap size in the lamination space 401. When label paper or protective film is running low, the swing frame 440 can be rotated to move the upper pressing roller 420 away from the lower pressing roller 430, opening the upper pressing roller 420 to facilitate refilling. Alternatively, when the gap size in the lamination space 401 needs to be increased, the swing frame 440 can be rotated to move the upper pressing roller 420 away from the lower pressing roller 430 to accommodate label paper and protective film of varying thicknesses.

[0045] To lock the relative position between the upper and lower pressure rollers 420 and 430, the swing frame 440's shaft 441 extends beyond the film lamination mounting frame 410. A locking handle 442 is connected to one end of the shaft 441. The film lamination mounting frame 410 is equipped with a locking member 411 that cooperates with the locking handle 442. The locking handle 442 cooperates with the locking member 411 to lock or unlock the shaft 441. When the shaft 441 is locked, the relative position between the upper and lower pressure rollers 420 and 430 is fixed; when the shaft 441 is unlocked, the relative position between the upper and lower pressure rollers 420 and 430 is adjustable.

[0046] Furthermore, the film laminating mounting frame 410 is connected to a limiting unit 450 along the movement path of the swing frame 440. The limiting unit 450 is equipped with an adjustable limiter 451, which can be a screw, and is adjusted through a threaded connection. When the swing frame 440 abuts the limiter 451, the limit position of the swing frame 440 is determined by the limiter 451. By adjusting the position of the limiter 451, the limit position of the swing frame 440 is adjusted accordingly. When refilling is required, the user unlocks the rotation of the swing frame 440 using the locking handle 442, opens the upper pressing roller 420 to facilitate refilling. After refilling, the user does not need to precisely rotate the swing frame 440 to return it to its initial position; the user only needs to rotate the swing frame 440 until it abuts the limiter 451. Finally, the user locks the rotation of the swing frame 440 using the locking handle 442, thereby limiting the gap size of the film laminating space 401.

[0047] It is understandable that the present invention does not limit the specific structure of the limiter 451. As long as the position of the limiter 451 is adjustable, no matter what structure the limiter 451 has, it falls within the protection scope of the present invention.

[0048] like Figures 1 to 4 As shown, for example, the film cutting mechanism 500 includes a film cutting mounting frame 510, a linear drive device 520, an up-down adjustment unit 530, and a cutting portion 540. The film cutting mounting frame 510 is fixedly connected to the mounting surface 110. The film cutting mounting frame 510 is connected to the linear drive device 520. The linear drive device 520 includes but is not limited to an electric push rod, a cylinder, a crank slider device, a gear rack moving device, and a pulley moving device. In this embodiment, the linear drive device 520 can be optionally a pulley moving device, which includes a cutting motor 521, a driving wheel, a driven wheel, and a synchronous belt. The cutting motor 521 drives the driving wheel to rotate. The driving wheel and the driven wheel are synchronously driven by the synchronous belt. A clamping plate 522 is fixedly connected to one side of the synchronous belt. The clamping plate 522 is connected to the up-down adjustment unit 530. The up-down adjustment unit 530 is provided with a connecting end 531 that can be raised and lowered. The cutting portion 540 is connected to the connecting end 531. The moving direction of the connecting end 531 is perpendicular to the conveying direction of the label paper and parallel to the width direction of the label paper. In addition, since the up-down adjustment unit 530 is provided, the up-down position of the cutting portion 540 is adjustable.

[0049] Furthermore, in order to avoid the linear drive device 520 from causing a stroke, the film cutting mounting frame 510 is provided with a proximity switch 550 on the moving path of the splint 522. When the splint 522 moves to trigger the proximity switch 550, the proximity switch 550 provides feedback to the control system, and the cutting motor 521 runs in the opposite direction under the control of the control system to achieve the reset of the splint 522.

[0050] In this embodiment, the cutting part 540 can be selected as a metal blade, but in some other embodiments, the cutting part 540 can also be selected as a laser cutting head, not limited to the above embodiment; the upper and lower adjustment unit 530 adjusts the upper and lower positions of the connecting end 531 through precision threads, and the accuracy can reach 0.01mm.

[0051] If the label paper roll 230 to be processed has a gap processed between each adjacent two label papers through the pre-process, then the height of the cutting part 540 needs to be adjusted to only cut the protective film without cutting the label paper, that is, the moving path of the cutting part 540 intersects with the moving path of the protective film; if the label paper roll 230 to be processed has not a gap processed between each adjacent two label papers, then the height of the cutting part 540 needs to be adjusted to only cut the protective film and the surface layer of the label paper without cutting the release layer of the label paper, that is, the moving path of the cutting part 540 intersects with the moving path of the surface layer.

[0052] like Figure 3 and Figure 4 As shown, for example, mounting surface 110 is provided with a chute 610 between film cutting mechanism 500 and label rewinding mechanism 700. Chute 610 is arranged along the conveying direction of the label paper. Sensor 600 is slidably connected to chute 610. A connector 620 defines the position of sensor 600 on chute 610, thereby adjusting the distance between sensor 600 and film cutting mechanism 500. Sensor 600 is provided with a sensing probe for identifying gaps. It can distinguish the gap between two labels by changes in brightness. This is prior art, so its structure and operating principle will not be described in detail here.

[0053] Furthermore, since there are generally only a few length specifications of label paper and they are not set arbitrarily, a plurality of sockets 611 are provided on the slide 610, and the induction sensor 600 is positioned on the slide 610 through the cooperation of the connecting piece 620 and the socket 611 to adapt to the length specifications of different label papers.

[0054] In order to conveniently adjust the distance between the sensing sensor 600 and the film cutting mechanism 500, the mounting surface 110 is provided with a scale (not shown in the drawings) along the moving direction of the sensing sensor 600. If the length specification of the label paper is 50 mm, then the user only needs to adjust the sensing sensor 600 to the corresponding 50 mm scale, thereby adjusting the straight-line distance between the sensing sensor 600 and the cutting part 540 to 50 mm.

[0055] Illustratively, the label rewinding mechanism 700 includes a label rewinding frame 710 and a label rewinding roller 720. The label rewinding frame 710 is fixedly connected to the mounting surface 110. The label rewinding frame 710 is rotatably connected to the label rewinding roller 720. The label rewinding roller 720 is driven by a label rewinding motor 730 and is used to rewind the laminated label paper. Since neither the first unwinding mechanism 200 nor the second unwinding mechanism 300 is equipped with a power source, the unwinding of the label paper and protective film is powered by the label rewinding roller 720.

[0056] With the above structure, during production, driven by the label winding mechanism 700, the first unwinding mechanism 200 and the second unwinding mechanism 300 unwind the label paper and the protective film respectively. When passing through the laminating space 401, the two are pressed against each other by the joint force of the upper pressing roller 420 and the lower pressing roller 430 and form a laminated label paper together. Subsequently, when the laminated label paper passes through the film cutting mechanism 500, the label winding mechanism 700 stops, and the linear reciprocating device drives the cutting part 540 to move along the width direction of the laminated label paper. If the label paper roll 230 has a gap between two adjacent label papers, then the cutting part 540 only needs to cut the protective film. If the label paper roll 230 does not have a gap between two adjacent label papers, then the cutting part 540 also needs to cut the surface layer of the label paper. After that, the label winding mechanism 700 is started again. When the induction sensor 600 detects the gap between the laminated label paper, the above-mentioned slitting process is repeated. Finally, the slit laminated label paper is wound on the first winding roller.

[0057] Since the distance between the sensing sensor 600 and the film cutting mechanism 500 is adjustable, the present invention can produce laminated label papers of different sizes and specifications, and since there is no tear line between two adjacent laminated label papers, when the laminated label papers produced by this technology are used in an automatic labeling machine, the laminated surface layer thereof can be smoothly separated from the laminated surface layer of other laminated label papers when peeling off the release layer, so as to meet the conditions for automatic labeling.

[0058] In some embodiments of the present invention, multiple tensioning mechanisms 900 are further mounted on the mounting surface 110. In this embodiment, there are two tensioning mechanisms 900, one of which is located between the first unwinding mechanism 200 and the laminating mechanism 400 and is used to maintain tension on the label paper. The other tensioning mechanism 900 is located between the inductive sensor 600 and the label rewinding mechanism 700 and is used to maintain tension on the laminated label paper. The present invention does not limit the specific number of tensioning mechanisms 900, and since tensioning mechanisms 900 are conventional in the art and have a variety of structures, the present invention does not limit the specific structure of the tensioning mechanisms 900.

[0059] like Figure 1As shown, in some embodiments of the present invention, since the protective film can adhere to contact objects when charged with static electricity, to eliminate adverse factors during the use of the laminated label paper, the mounting surface 110 is provided with a pad 130 below the cutting portion 540. The surface of the pad 130 is provided with air holes 131. In this embodiment, there are multiple air holes 131. The pad 130 has a built-in ion generator. When the ion generator is powered, it generates negative ions. The negative ions diffuse through the air holes 131 toward the laminated label paper, thereby removing the positive charge in the laminated label paper.

[0060] like Figure 2 As shown, in some embodiments of the present invention, to detect the presence of label paper and / or protective film, the first unwinding mechanism 200 and / or the second unwinding mechanism 300 are equipped with a material shortage sensor 240. When material passes through the material shortage sensor 240, the material shortage sensor 240 feeds back a material shortage signal to the control system, and the label laminator operates normally. When the material shortage sensor 240 detects no material, i.e., when material shortage occurs, the material shortage sensor 240 feeds back a material shortage signal to the control system, causing the label laminator to stop operating and issue an alarm to remind the user to refill the material.

[0061] In this embodiment, only the first unwinding mechanism 200 is provided with a material shortage sensor 240. Since the length of the protective film roll 330 is an integer multiple of the label paper roll 230, the protective film roll 330 needs to be replenished after each integer replenishment of the label paper roll 230.

[0062] Of course, in some other embodiments, both the first unwinding mechanism 200 and the second unwinding mechanism 300 are provided with a material shortage sensor 240 , and are not limited to the above embodiment.

[0063] The laminated label paper according to the second embodiment of the present invention is produced by the above-mentioned label laminating machine.

[0064] Since the laminated label paper adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
