Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box color printing technology, and in particular to a laminating machine for cardboard box color printing production. Background Technology
[0002] In the production and processing of cardboard boxes, color printing and lamination are key processes for improving the appearance quality and protective performance of the boxes. Among them, the cleanliness of the cardboard box surface directly affects the adhesion of the color printed pattern and the firmness of the lamination. If there are impurities such as dust and debris on the surface, it is very easy to cause defects in the color printed pattern, bubbles or peeling of the lamination. Therefore, it is essential to effectively clean the surface of the cardboard box before color printing and lamination.
[0003] To achieve the cleaning treatment of cardboard box surfaces, various related devices have emerged in the prior art. For example, Chinese utility model patent (publication number CN221698068U) discloses a cardboard box color printing and laminating machine, which scrapes away impurities from the cardboard surface by setting up a cleaning structure. This cleaning structure includes a scraper driven by a hydraulic rod. The scraper is buffered by a telescopic rod and a spring to avoid hard contact with the cardboard surface. At the same time, it works in conjunction with an electrostatic adsorption component at the rear to further clean impurities.
[0004] However, existing cleaning methods still have significant shortcomings: Firstly, the scraper needs to maintain continuous contact with the carton surface to achieve the scraping action. During this process, dust, particles, and other impurities that are scraped off tend to accumulate at the contact end between the scraper and the carton, and cannot be removed from the contact area in time. This may not only cause secondary contamination of the carton surface, but also affect the scraping effect of the scraper due to the accumulation of impurities. Secondly, the electrostatic adsorption roller used for auxiliary cleaning will have a significantly reduced surface adsorption capacity after adsorbing a certain amount of particles. Existing equipment lacks an automatic cleaning mechanism for the electrostatic adsorption roller, which requires manual cleaning at regular intervals. This not only increases the operational burden, but may also affect the overall cleaning efficiency due to untimely cleaning, thereby adversely affecting the quality of subsequent color printing and lamination. Utility Model Content
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a laminating machine for color printing production of cardboard boxes.
[0006] A laminating machine for color printing production of cardboard boxes designed for this purpose includes a frame and a conveyor belt mounted on the frame. The frame is fixedly connected to a gantry frame. The gantry frame is movably equipped with a movable seat that moves up and down relative to the gantry frame. The movable seat is equipped with a cleaning component. The gantry frame is equipped with a lifting module for driving the movable seat to move up and down relative to the gantry frame.
[0007] The cleaning assembly includes a swing seat that is rotatably disposed relative to the movable seat, and cleaning brushes are arranged at intervals on the lower surface of the swing seat.
[0008] The swing seat is hollow inside and has a first dust suction channel. The swing seat is provided with a first dust suction connector that communicates with the first dust suction channel. A first dust suction port that communicates with the first dust suction channel is provided on the lower surface of the swing seat between the front and rear cleaning brushes.
[0009] The movable seat is provided with a drive module for driving the swing seat to swing back and forth relative to the movable seat;

[0016] Preferably, the movable seat is provided with a through opening extending vertically, the cleaning brush is located below the through opening, and the swing seat extends through the through opening to the top of the movable seat.
[0017] Preferably, the gantry frame is provided with a slide rail, and the movable seat is slidably connected to the slide rail.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a swing seat that can swing back and forth relative to the movable seat, and arranging cleaning brushes at intervals on the lower surface of the swing seat, the swing seat is driven to swing back and forth by a drive module, so that the cleaning brushes can dynamically sweep and clean the surface of the carton.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] See Figures 1-4A laminating machine for color printing of cardboard boxes includes a frame 10 and a conveyor belt 20 disposed on the frame 10. A gantry frame 100 is fixedly connected to the frame 10. A movable seat 30 is movably disposed on the gantry frame 100 and moves vertically relative to it. A cleaning assembly 40 is disposed on the movable seat 30. A lifting module 70 is disposed on the gantry frame 100 to drive the movable seat 30 to move vertically relative to the gantry frame 100. The cleaning assembly 40 includes a swing seat 410 rotatably disposed relative to the movable seat 30. The lower table of the swing seat 410... Cleaning brushes 420 are arranged at intervals on the front and back of the surface; the swing seat 410 is hollow inside and has a first dust suction channel 430, and the swing seat 410 is provided with a first dust suction connector 440 that communicates with the first dust suction channel 430; a first dust suction port 450 that communicates with the first dust suction channel 430 is provided on the lower surface of the swing seat 410 between the front and back cleaning brushes 420; the moving seat 30 is provided with a drive module 50 for driving the swing seat 410 to swing back and forth relative to the moving seat 30; the conveyor belt 20 is used to move the carton from back to front.
[0025] The working principle of this utility model is as follows:
[0026] During operation, the conveyor belt transports cartons from back to front. As the cartons approach the cleaning area, the lifting module drives the moving seat to move downwards relative to the gantry, bringing the cleaning brushes of the cleaning components close to the carton surface and maintaining appropriate pressure. Subsequently, the drive module drives the swing seat to swing back and forth relative to the moving seat, causing the cleaning brushes arranged at intervals to swing synchronously, dynamically sweeping the surface of the cartons conveyed below, loosening and lifting dust, particles, and other impurities attached to the surface.
[0027] At the same time, the vacuuming device connected to the first vacuuming connector is started, and a negative pressure is formed in the first vacuuming channel inside the swing seat. The first vacuuming port between the front and rear cleaning brushes generates suction force, which sucks the impurities swept up by the brushes into the first vacuuming channel in time, and discharges them to the external collection device through the first vacuuming connector, so as to avoid the impurities from scattering and causing secondary pollution.
[0028] Once the carton has completely passed through the cleaning area and cleaning is complete, the conveyor belt continues to move the cleaned carton forward into the laminating area. At this point, the laminating machine uses the existing laminating structure to perform a laminating operation on the cleaned carton, thus completing the laminating process of the entire carton color printing production.
[0029] See Figure 2The swing seat 410 has rotating shafts connected to its left and right sides, and these rotating shafts are rotatably connected to the movable seat 30. The drive module 50 includes a first motor 510 fixedly mounted on the movable seat 30. A first gear 520 is mounted on the motor shaft of the first motor 510, and a second gear 530 meshing with the first gear 520 is fixedly connected to the rotating shaft. In the drive module, the first motor drives the meshing first and second gears to rotate, thereby causing the rotating shafts on both sides of the swing seat to rotate relative to the movable seat, thus realizing the back-and-forth swing of the swing seat, providing dynamic cleaning power for the cleaning brush, and ensuring effective cleaning of the cardboard box surface.
[0030] See Figures 2 to 4 The lifting module 70 includes a cylinder 710 fixedly mounted on the gantry frame 100. A connecting frame 720 is fixedly connected to the cylinder shaft of the cylinder 710, and the connecting frame 720 is fixedly connected to the movable seat 30. In the lifting module, the cylinder drives the connecting frame and the movable seat to move up and down through the extension and retraction of its cylinder shaft, thereby adjusting the distance between the cleaning components and the surface of the cardboard box to adapt to the cleaning needs of cardboard boxes of different thicknesses and ensure that the cleaning brush maintains appropriate contact pressure with the cardboard box surface.
[0031] In this invention, other existing linear modules can also be used to replace the cylinder 710 as the drive source. Besides the cylinder, existing linear modules that can replace it as the drive source for the lifting module include, but are not limited to, the following types:
[0032] Electric linear actuator: The motor drives the lead screw to rotate, which in turn drives the linear actuator to extend and retract to achieve linear motion. It features high control precision, stable thrust, and flexible adjustment of lifting height through forward and reverse rotation of the motor. It is suitable for scenarios with certain requirements for lifting speed and position control.
[0033] Ball screw slide module: The ball screw is driven by a motor to rotate, so that the slider moves linearly back and forth along the guide rail. It has high transmission efficiency, high positioning accuracy (up to 0.01mm level), and smooth operation. It can accurately control the lifting height of the moving seat and is suitable for working conditions with high requirements for the adjustment accuracy of the spacing of cleaning components.
[0034] Synchronous belt linear module: The synchronous belt pulley is driven by a motor to rotate, and the synchronous belt drives the slider to move along the guide rail. It has the advantages of high speed, low noise and customizable stroke, and is suitable for scenarios with high lifting speed requirements and long stroke.
[0035] Gear and rack linear module: The motor drives the gear to rotate, and the gear meshes with the rack to drive the module to move in a straight line. It has a strong load-bearing capacity and stable operation. It can achieve smooth lifting and lowering of the moving seat under heavy loads, and is suitable for situations where the cleaning components are heavy.
[0036] See Figure 4The swing base 410 has dust collection boxes 60 on its front and rear sides, which are fixedly mounted on the movable base 30. Each dust collection box 60 has a hollow interior with a second dust collection channel 610 and a second dust collection connector 620 communicating with the second dust collection channel 610. A second dust collection port 630 communicating with the second dust collection channel 610 is located on the lower surface of the dust collection box 60. The dust collection boxes on the front and rear sides of the swing base have their internal second dust collection channels connected to external vacuuming equipment via the second dust collection connectors. During operation, negative pressure is created at the second dust collection port. This allows for timely adsorption of impurities that may be scattered to the front and rear sides during cleaning by the cleaning brush, forming an all-around dust collection effect in conjunction with the first dust collection port, further reducing secondary pollution from impurities and significantly improving cleaning efficiency.
[0037] See Figure 4 The movable seat 30 is provided with a through-hole 310 extending vertically. The cleaning brush 420 is located below the through-hole 310, and a portion of the swing seat 410 extends through the through-hole 310 to above the movable seat 30. See also Figure 2 The rotating shaft is connected to the swing seat 410 located above the movable seat 30.
[0038] In this utility model, the gantry frame 100 is provided with a slide rail, and the movable seat 30 is slidably connected to the slide rail.
