Description

Technical Field

[0001] This invention relates to the field of paperboard coating technology, specifically to a paperboard coating apparatus for paperboard processing. Background Technology

[0002] Lamination is a major post-printing process that involves bonding a plastic film coated with adhesive to printed paper through heating and pressure, creating a paper-plastic composite product. It is one of the most common post-printing processes for paper products. Laminated printed materials have a smoother and glossier surface due to the thin, transparent plastic film, which not only improves the gloss and durability of the printed material and extends its lifespan, but also provides protection against moisture, water, stains, wear, folding, and chemical corrosion.

[0003] Citing the Chinese patent with publication number "CN220973335U", a conveyor and a laminating device installed on the conveyor are described. The conveyor is equipped with a positioning device for limiting the movement of cardboard during transport. The positioning device includes a pressing mechanism and an adjusting mechanism. The pressing mechanism is used to press and fix the upper surface of the cardboard during transport. The adjusting mechanisms are a pair and symmetrically arranged on both sides of the conveyor. The two adjusting mechanisms can respectively limit the movement of both sides of the cardboard. The two adjusting mechanisms are connected by a drive assembly. The positioning device is installed on the conveyor, and the positioning device includes a pressing mechanism and a pair of adjusting mechanisms.

[0004] Cardboard itself has low rigidity, and cleaning with a hard-contact brush can easily damage the cardboard and affect the lamination effect; direct air blowing cannot effectively remove impurities attracted by static electricity, making it difficult to guarantee the lamination quality.

[0015] Preferably, the surface of the arc-shaped collecting block is provided with a through groove, one end of the arc-shaped collecting block is disposed inside the fixed cylinder, and the other end of the arc-shaped collecting block is provided with a protrusion.

[0016] This invention provides a paperboard laminating apparatus for paperboard processing. It has the following advantages: 1. This paperboard laminating device for paperboard processing, by setting an impact rod, activates an impact cylinder to drive a first fixed block to move towards the bottom of the paperboard. After the first fixed block reaches the bottom of the second limit block, the buffer airbag contacts the bottom of the paperboard. Under the action of inertia and the second cylindrical spring, the impact rod continuously reciprocates through the buffer airbag 412 to impact the bottom of the paperboard. Multiple second cylindrical springs cause larger impurities on the top of the paperboard to detach from the surface of the paperboard. In conjunction with the rotation of the rotating cylinder, the arc-shaped collecting block collects the larger impurities, avoiding damage to the printing layer and surface texture of the paperboard by direct scraping with hard tools and impact of high-speed airflow on the top of the paperboard, thereby improving the quality of subsequent lamination.

[0017] 2. This paperboard laminating device for paperboard processing incorporates a buffer airbag. The buffer airbag first contacts the bottom of the paperboard, and its elastic deformation evenly disperses the impact force, preventing direct hard contact between the impact rod and the paperboard. The buffer airbag also absorbs the reaction force generated by the impact, preventing damage to the paperboard from the impact rod while fully preserving the impact impurity removal effect. Furthermore, an arc-shaped plate is installed inside the impurity collection box to promptly collect impurities falling from the surface of the buffer airbag and prevent impurities from being poured out, thus preventing impurities from re-adhering to the surface of the buffer airbag and embedding into the interior of the paperboard, thereby improving the quality of subsequent lamination.

[0018] 3. This paperboard laminating device for paperboard processing, by setting a protrusion at the other end of the arc-shaped collecting block, activates the blower and suction equipment. While the rotating drum rotates, the protrusion at one end of the arc-shaped collecting block directly sucks the lighter impurities on the surface of the paperboard into the fixed cylinder through the anti-tipping collecting box and collects them. Furthermore, a sensor and auxiliary cleaning mechanism are set in conjunction. When the sensor rotates to the position of the infrared generator, the second drive motor is activated to drive the auxiliary cleaning mechanism to rotate, preventing some impurities from accumulating on the surface of the arc-shaped collecting block. In conjunction with the impact of the impact rod, the impurities are completely covered and cleaned, improving the quality of subsequent lamination. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0023] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a paperboard laminating device for paperboard processing, comprising a support frame 1, a support beam 2 fixedly connected to the bottom of the support frame 1, a laminating device 3 provided on the top of the support frame 1, a limiting mechanism 7 and a rotating collection mechanism 6 fixedly connected to the top of the support frame 1, a vibration cleaning mechanism 4 fixedly connected to the top of the support beam 2, and the rotating collection mechanism 6 comprising a third fixing block 612, the surface of the third fixing block 612 being rotatably connected to a rotating cylinder 5; Vibration cleaning mechanism 4 includes: Impact rod 411 is slidably connected inside the second fixed rod 410, and a second cylindrical spring 413 is fixedly connected to the surface of the impact rod 411. The buffer airbag 412 is fixedly connected to the surface of the second fixed rod 410. The buffer airbag 412 is made of a high-resilience elastic material. It absorbs only excessive rigid impact force and can still transmit sufficient instantaneous acceleration to the cardboard to ensure that large mass impurities obtain sufficient detachment force.

[0024] The top of the impact rod 411 is provided with a ball, the bottom of the impact rod 411 is fixedly connected to the second cylindrical spring 413, and the bottom of the impact rod 411 is provided with a through groove.

[0025] The vibration cleaning mechanism 4 also includes an impact cylinder 41, which is fixedly connected to the bottom of the support beam 2. A first fixing rod 42 is fixedly connected to the top of the support beam 2. A first fixing block 44 is slidably connected to the surface of the first fixing rod 42. A second fixing block 45 is fixedly connected to the top of the first fixing block 44. A second fixing rod 410 is fixedly connected to the top of the second fixing block 45. An impurity collection box 48 is fixedly connected to the top of the second fixing block 45.

[0026] A first limiting block 43 is fixedly connected to the surface of the first fixing rod 42. A buffer pad is provided on the top of the first limiting block 43. A second limiting block 47 is fixedly connected to the top of the first fixing rod 42. A first cylindrical spring 46 is fixedly connected to the surface of the first fixing block 44. The first cylindrical spring 46 is slidably connected to the first fixing rod 42. The bottom of the second limiting block 47 is fixedly connected to the first cylindrical spring 46. An arc-shaped plate 49 is fixedly connected inside the impurity collection box 48.

[0027] A third drive motor 8 is fixedly connected to the surface of the support frame 1. A rotating roller 10 is fixedly connected inside the third drive motor 8 through its output shaft. A conveyor belt 9 is rotatably connected to the surface of the rotating roller 10.

[0028] The limiting mechanism 7 includes a fourth fixing block 72, which is fixedly connected to the top of the support frame 1. An electric push rod motor 71 is fixedly connected to the surface of the fourth fixing block 72. A fifth fixing block 73 is fixedly connected inside the electric push rod motor 71 through an output shaft. A first limiting roller 74 is rotatably connected inside the fifth fixing block 73. A limiting wheel 75 is fixedly connected to the surface of the film coating device 3.

[0029] In use, the cardboard is placed on top of the conveyor belt 9. Then, the third drive motor 8 is started, which drives the rotating roller 10 to rotate via its output shaft. The rotation of the rotating roller 10 drives the conveyor belt 9 to rotate, which in turn moves the cardboard toward the laminating equipment 3. At the same time, the electric push rod motor 71 is started, which drives the fifth fixing block 73 to move toward the edge of the cardboard via its output shaft. The first limiting roller 74 is adjusted to a suitable position, thereby limiting the position of the cardboard. The limiting wheel 75 further limits the cardboard to a flat position, facilitating lamination by the laminating equipment 3. During the cardboard conveying process, the impact cylinder 41 is started, which drives the first fixing block 44 and the first fixing block 44 to move toward the edge of the cardboard via its output shaft. The second fixing block 45 moves toward the bottom of the cardboard, and then the impact cylinder 41 is closed. When the first fixing block 44 moves to the bottom position of the second limit block 47, the first fixing block 44 stops instantly. At this time, the buffer airbag 412 first contacts the cardboard. Then, under the action of inertia and the second cylindrical spring 413, the impact rod 411 continues to reciprocate through the buffer airbag 412 to impact the bottom of the cardboard, so that the impurities on the top of the cardboard are removed from the surface of the cardboard. The impurities falling from the bottom of the cardboard and the impurities falling off the surface of the buffer airbag 412 finally fall into the impurity collection box 48 and are collected. Then, the first fixing block 44 returns to its original position under the action of the first cylindrical spring 46.

[0030] By setting the impact rod 411, the impact cylinder 41 is activated to drive the first fixed block 44 to move towards the bottom of the cardboard. After the first fixed block 44 reaches the bottom of the second limit block 47, the buffer airbag 412 contacts the bottom of the cardboard. Under the action of inertia and the second cylindrical spring 413, the impact rod 411 continuously reciprocates through the buffer airbag 412 to impact the bottom of the cardboard. Multiple second cylindrical springs 413 cause larger impurities on the top of the cardboard to detach from the surface of the cardboard. In conjunction with the rotation of the rotating cylinder 5, the arc-shaped collecting block 63 collects the larger impurities, avoiding damage to the printing layer and surface texture of the cardboard by direct scraping with hard tools and impact of high-speed airflow on the top of the cardboard, thus improving the quality of subsequent lamination.

[0031] By setting up a buffer airbag 412, the buffer airbag 412 first contacts the bottom of the cardboard. The impact force is evenly dispersed by the elastic deformation of the buffer airbag 412 itself, avoiding direct hard contact between the impact rod 411 and the cardboard. The buffer airbag 412 can absorb the reaction force generated by the impact, preventing the impact rod 411 from damaging the cardboard, while fully preserving the effect of impact impurity removal. In addition, an arc-shaped plate 49 is set inside the impurity collection box 48 to collect the impurities that fall from the surface of the buffer airbag 412 in a timely manner and prevent the impurities from being poured out, preventing the impurities from being re-adhered to the surface of the buffer airbag 412, and preventing the impurities from being embedded in the interior of the cardboard, thereby improving the quality of subsequent lamination.

[0032] Example 2: Please refer to Figure 1-12 Based on Embodiment 1, the present invention provides a technical solution: The third fixing block 612 is fixedly connected to the top of the support frame 1. The surface of the third fixing block 612 is fixedly connected to the first drive motor 61. The interior of the first drive motor 61 is fixedly connected to the rotating cylinder 5 through the output shaft. The top of the third fixing block 612 is fixedly connected to the infrared generator 65.

[0033] An arc-shaped collecting block 63 is fixedly connected to the surface of the rotating cylinder 5. A second drive motor 62 is fixedly connected to the surface of the arc-shaped collecting block 63. An auxiliary cleaning mechanism 66 is fixedly connected inside the second drive motor 62 through its output shaft. A sensor 64 is fixedly connected to the surface of the arc-shaped collecting block 63.

[0034] An anti-tipping collection box 68 is fixedly connected inside the rotating cylinder 5. A fixed cylinder 69 is fixedly connected to the surface of the anti-tipping collection box 68. A blower / suction device 610 is fixedly connected inside the fixed cylinder 69. A connecting pipe 67 is fixedly connected inside the blower / suction device 610, and the blower / suction device 610 is connected to the fixed cylinder 69 through the connecting pipe 67. An exhaust pipe 611 is fixedly connected to the surface of the blower / suction device 610.

[0035] The surface of the arc-shaped collecting block 63 is provided with a through groove, and one end of the arc-shaped collecting block 63 is located inside the fixed cylinder 69, while the other end of the arc-shaped collecting block 63 is provided with a protrusion.

[0036] In use, the blower / suction device 610 is first started, continuously drawing air through the connecting pipe 67 and expelling it through the exhaust pipe 611. Then, the first drive motor 61 is started, and the start of the first drive motor 61 drives the rotating cylinder 5 to rotate at an appropriate speed through the output shaft, thereby collecting heavier impurities that have detached from the surface of the cardboard through the arc-shaped collection block 63. At this time, some impurities fall directly into the interior of the arc-shaped collection block 63 through the through holes opened on the surface of the arc-shaped collection block 63, and some impurities accumulate on the surface of the arc-shaped collection block 63. Then, the rotating cylinder 5 continues to rotate. When the sensor 64 rotates to the same height as the infrared generator 65 and rotates to the sensing area of ​​the infrared generator 65, the second drive motor 62 is started, driving the auxiliary cleaning mechanism 66 to rotate through the output shaft. The impurities, due to gravity, the rotation of the auxiliary cleaning mechanism 66, and the continuous operation of the blower / suction device 610, are finally all discharged through the anti-tipping collection box 68 into the interior of the fixed cylinder 69. After cleaning, the cardboard continues to be conveyed to the position of the laminating device 3, and then the laminating device 3 completes the lamination of the cardboard.

[0037] By providing a protrusion at the other end of the arc-shaped collection block 63, the blower suction device 610 is activated. As the rotating cylinder 5 rotates, the protrusion at one end of the arc-shaped collection block 63 directly draws lighter impurities from the cardboard surface into the fixed cylinder 69 through the anti-tipping collection box 68. Furthermore, a sensor 64 and an auxiliary cleaning mechanism 66 are provided. When the sensor 64 rotates to the position of the infrared generator 65, the second drive motor 62 is activated to drive the auxiliary cleaning mechanism 66 to rotate, preventing some impurities from accumulating on the surface of the arc-shaped collection block 63. This, combined with the impact of the impact rod 411, achieves full coverage cleaning of impurities, improving the quality of subsequent lamination.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
