Description

Technical Field

[0001] The present invention belongs to the technical field of carton production. Specifically, it particularly relates to a composite film laminating device for carton film laminating. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. To prevent cartons from being damaged due to moisture during use, during the production process of cartons, it is necessary to perform film laminating work on the surface of cardboard through a film laminating device.

[0003] In the film laminating process, when the film is pressed against the surface of the carton through an extrusion device, the pre-coated hot melt adhesive on the film has enhanced fluidity under high temperature and high pressure, and some adhesives will overflow outward from the edges of the cardboard or the areas that are not fully covered. Since the extrusion roller is in direct contact with the film, the overflowed adhesive is easily attached to the roller surface and gradually cools and hardens with temperature fluctuations during continuous operation, forming local protrusions or residual layers. These hardened colloids not only reduce the contact uniformity between the extrusion roller and the film, resulting in an imbalance in the pressure distribution during subsequent pressing, but also may scratch the film surface or cause local delamination of the carton, seriously affecting the smoothness and bonding strength of the laminated finished product. Summary of the Invention

[0004] Aiming at the problem that the hot melt adhesive on the film is easy to overflow and attach to the surface of the extrusion roller under extrusion, the present invention proposes a composite film laminating device for carton film laminating to overcome the above-mentioned technical problems existing in the related prior art.

A transportation motor is fixedly installed on the outer surface of the transportation frame, and the output end of the transportation motor is fixedly connected to the transportation roller.

[0009] Further, the extrusion component includes an upper extrusion roller and a lower extrusion roller. A plurality of the upper extrusion rollers and the lower extrusion rollers are arranged in an array inside the machine table. One end of each of the upper extrusion roller and the lower extrusion roller is fixedly connected with a sprocket. A chain is meshed on the outer surface of the sprocket.

A driving motor is fixedly installed outside the machine table, and the output end of the driving motor is fixedly connected to the upper extrusion roller.

[0010] Further, the blocking and scraping component includes an upper scraping plate and a lower scraping plate. The upper scraping plate is inclined and arranged outside the upper extrusion roller. The lower scraping plate is inclined and arranged outside the lower extrusion roller. A plurality of installation grooves are formed in the inner wall of the machine table corresponding to the upper scraping plate and the lower scraping plate. An installation cylinder is fixedly installed inside the installation groove. A rotating shaft is rotatably connected inside the installation cylinder. A torsion spring is fixedly connected between the rotating shaft and the inner wall of the installation cylinder. One end of the rotating shaft extends outside the installation cylinder and is fixedly connected to the corresponding upper scraping plate or lower scraping plate.

[0011] Further, the pushing and cleaning component includes a pushing block. The pushing block is movably connected to the top of the upper scraping plate and the outer surface of the upper extrusion roller respectively. A pushing frame is fixedly connected to the top of the pushing block. A screw rod is rotatably connected to the inner wall of the machine table. The screw rod is threadedly connected to the pushing frame. A guide rod is fixedly connected to the inner wall of the machine table. The guide rod is movably connected to the pushing frame. A pushing motor is fixedly connected to the outer surface of the machine table, and the output end of the pushing motor is fixedly connected to the screw rod.

[0012] Further, the collection component includes a connection groove. The connection groove is formed on both sides of the inner wall of the machine table and corresponds to the pushing block.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention drives the extrusion assembly so that the cardboard can pass through between the extrusion assemblies. During this process, the film can continuously adhere to the cardboard under the extrusion of the extrusion assembly. At the same time, during the rotation of the extrusion end, it can rotate past the blocking and scraping assembly, so that the scraping end of the blocking and scraping assembly can scrape the hot melt adhesive attached to the extrusion end. This setting ensures that when the extrusion end comes into contact with the cardboard and the film again, there is no hot melt adhesive on its surface, effectively avoiding the phenomenon that the hot melt adhesive accumulates and hardens on the extrusion end, resulting in an imbalance in the pressure distribution during pressing by the extrusion end and scratching the surface of the film.

[0016] 2. The present invention sets the upper scraping plate to tilt upward, thus avoiding the phenomenon that the hot melt adhesive scraped off by the upper scraping plate will fall back onto the top of the cardboard again. At the same time, through the driving motor, screw rod and pushing frame, several pushing blocks can push the hot melt adhesive accumulated on the upper scraping plate, so that the hot melt adhesive can move into the through groove through the connecting groove and directly fall into the collection box under the guidance of the through groove. The above settings ensure that the cleaned hot melt adhesive does not accumulate on the upper scraping plate, thus guaranteeing the overall cleaning effect of the upper scraping plate.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without making creative efforts belong to the scope of protection of the invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0030] Please refer to Figures 1-7 As shown, the present invention is a composite film laminating device for carton film laminating, including a machine table 1. Transportation components 2 are arranged on both sides of the machine table 1. An extrusion component 3 is arranged inside the machine table 1. A blocking and scraping component 4 is arranged at the extrusion end of the extrusion component 3. A pushing and cleaning component 5 is arranged at the scraping end of the blocking and scraping component 4. A collection component 6 is arranged inside the machine table 1;

[0031] The transportation component 2 is used to transport the cardboard into the machine table 1 so that the cardboard can perform film laminating operations. The extrusion component 3 is used to extrude the cardboard and the film. The blocking and scraping component 4 is used to scrape the hot melt adhesive attached to the extrusion end. The pushing and cleaning component 5 is used to push the hot melt adhesive on the blocking and scraping component 4 into the collection component 6.

[0032] By placing the cardboard on the transport assembly 2, after the transport assembly 2 transports the cardboard between the extrusion assemblies 3, the film is extruded onto the cardboard under the extrusion of the extrusion end of the extrusion assembly 3. At this time, the extrusion end of the extrusion assembly 3 rotates continuously, enabling the cardboard to move continuously between the extrusion assemblies 3, and at the same time, the film also continuously adheres to the cardboard; during the above process, when the extrusion end rotates past the blocking and scraping assembly 4, the blocking and scraping assembly 4 can scrape off the hot melt adhesive adhering to the outer surface of the extrusion end.

[0033] By driving the extrusion assembly 3, the cardboard can pass through between the extrusion assemblies 3. During this process, the film can continuously adhere to the cardboard under the extrusion of the extrusion assembly 3. At the same time, during the rotation of the extrusion end, it can rotate past the blocking and scraping assembly 4, so that the scraping end of the blocking and scraping assembly 4 can scrape off the hot melt adhesive adhering to the extrusion end. This setting ensures that there is no hot melt adhesive on the surface of the extrusion end when it comes into contact with the cardboard and the film again, effectively avoiding the phenomena of hot melt adhesive accumulation and hardening on the extrusion end, resulting in unbalanced pressure distribution during pressing and scratching the surface of the film.

[0034] In one embodiment, for the above-mentioned transport assembly 2, the transport assembly 2 includes a transport frame 201. The transport frame 201 is fixedly installed on one side of the machine table 1. A transport roller 202 is rotatably connected inside the transport frame 201. A transport belt 203 is arranged on the outer surface of the transport roller 202. A transport motor 204 is fixedly installed on the outer surface of the transport frame 201. The output end of the transport motor 204 is fixedly connected to the transport roller 202.

[0035] The transport roller 202 is driven by the transport motor 204, and the rotating transport roller 202 drives the transport belt 203 to rotate inside the transport frame 201. When performing the film laminating operation on the cardboard, the cardboard is placed on the transport belt 203 on one side of the machine table 1. At this time, the moving transport belt 203 can drive the cardboard to move into the machine table 1 for the film laminating operation. When the laminated cardboard moves out of the machine table 1, the transport belt 203 on the other side can transport it to the next processing point.

[0036] In one embodiment, for the above-mentioned extrusion assembly 3, the extrusion assembly 3 includes an upper extrusion roller 301 and a lower extrusion roller 302. A plurality of the upper extrusion rollers 301 and the lower extrusion rollers 302 are arranged in an array inside the machine table 1. One end of each of the upper extrusion roller 301 and the lower extrusion roller 302 is fixedly connected with a sprocket 303. A chain 304 is engaged with the outer surface of the sprocket 303. The other end of each of the upper extrusion roller 301 and the lower extrusion roller 302 is fixedly installed with a gear 305. Two of the gears 305 arranged up and down are engaged with each other. A driving motor 306 is fixedly installed outside the machine table 1. The output end of the driving motor 306 is fixedly connected with the upper extrusion roller 301.

[0037] By driving the upper extrusion roller 301 through the driving motor 306, the rotating upper extrusion roller 301 drives all the upper extrusion rollers 301 to rotate synchronously through the corresponding sprockets 303 and the chain 304. At the same time, the rotating upper extrusion roller 301 drives the corresponding lower extrusion roller 302 to rotate through the gears 305 engaged with each other on both sides. At this time, all the upper extrusion rollers 301 and the lower extrusion rollers 302 can rotate towards each other. This setting enables the cardboard to pass through between the upper extrusion roller 301 and the lower extrusion roller 302 better, and at the same time, it is also convenient for the subsequent blocking and scraping assembly 4 to clean the hot melt adhesive attached to the surface of the continuously rotating extrusion roller.

[0038] In one embodiment, for the above-mentioned blocking and scraping assembly 4, the blocking and scraping assembly 4 includes an upper scraping plate 401 and a lower scraping plate 402. The upper scraping plate 401 is inclined and arranged outside the upper extrusion roller 301. The lower scraping plate 402 is inclined and arranged outside the lower extrusion roller 302. A plurality of installation grooves 403 are formed in the inner wall of the machine table 1 corresponding to the upper scraping plate 401 and the lower scraping plate 402. An installation cylinder 404 is fixedly installed inside the installation groove 403. A rotating shaft 405 is rotatably connected inside the installation cylinder 404. A torsion spring 406 is fixedly connected between the rotating shaft 405 and the inner wall of the installation cylinder 404. One end of the rotating shaft 405 extends to the outside of the installation cylinder 404 and is fixedly connected with the corresponding upper scraping plate 401 or the lower scraping plate 402.

[0039] The torsion spring 406 can pull the rotating shaft 405, so that the upper scraping plate 401 and the lower scraping plate 402 can be in contact with the corresponding extrusion roller obliquely, and the upper scraping plate 401 and the lower scraping plate 402 are symmetrically arranged. This setting enables the corresponding scraping plate to normally scrape and clean the hot melt adhesive attached to the extrusion roller when the upper extrusion roller 301 and the lower extrusion roller 302 rotate towards each other and rotate past the corresponding scraping plate. In order to prevent the hot melt adhesive scraped off by the upper scraping plate 401 from falling onto the top of the continuously moving cardboard, the upper scraping plate 401 is inclined upwards.

[0040] In one embodiment, for the above-mentioned pushing and cleaning component 5, the pushing and cleaning component 5 includes a pushing block 501, the pushing block 501 is movably connected to the top of the upper scraping plate 401 and the outer surface of the upper pressing roller 301 respectively, a pushing frame 502 is fixedly connected to the top of the pushing block 501, a screw rod 503 is rotatably connected to the inner wall of the machine table 1, the screw rod 503 is threadedly connected to the pushing frame 502, a guide rod 504 is fixedly connected to the inner wall of the machine table 1, the guide rod 504 is movably connected to the pushing frame 502, and a pushing motor 505 is fixedly connected to the outer surface of the machine table 1, and the output end of the pushing motor 505 is fixedly connected to the screw rod 503.

[0041] The screw rod 503 is driven by the pushing motor 505 and continuously rotates. The screw rod 503 can push a plurality of pushing blocks 501 through the pushing frame 502, so that the pushing blocks 501 can push the hot melt adhesive scraped by the upper scraping plate 401. At this time, the scraped hot melt adhesive can directly fall into the collecting component 6 after moving to one side of the upper scraping plate 401. The above setting makes the cleaned hot melt adhesive not accumulate on the upper scraping plate 401, so that the overall cleaning effect of the upper scraping plate 401 can be guaranteed.

[0042] In one embodiment, for the above-mentioned collecting component 6, the collecting component 6 includes a connecting groove 601, the connecting groove 601 is opened on both sides of the inner wall of the machine table 1, the connecting groove 601 corresponds to the pushing block 501, a through groove 602 is opened inside the machine table 1, the connecting groove 601 is connected to the through groove 602, a collecting groove 603 is opened at the bottom of the inner wall of the through groove 602, a collecting box 604 is movably connected inside the collecting groove 603, and a blanking groove 605 is opened at the top of the lower scraping plate 402.

[0043] The scraped hot melt adhesive moves into the through groove 602 through the connecting groove 601 under the push of the pushing block 501. At this time, the hot melt adhesive can fall downward along the through groove 602 under the action of its own gravity and directly fall into the collecting box 604. And because the connecting grooves 601 are arranged on both sides of the inner wall of the machine table 1, the pushing block 501 can move reciprocally on the upper scraping plate 401 normally; after the lower scraping plate 402 scrapes off the hot melt adhesive attached to the lower pressing roller 302, since the lower scraping plate 402 is inclined upward, the scraped hot melt adhesive can flow downward along the lower scraping plate 402 under the action of its own gravity. When passing through the blanking groove 605, the hot melt adhesive falls under the action of its own gravity and directly falls into the collecting box 604.

[0044] In one embodiment, for the above-mentioned machine table 1, an air pipe 606 is provided at the top of the machine table 1 corresponding to the through groove 602, and a connecting pipe 607 is fixedly connected to the outside of the air pipe 606.

[0045] The connecting pipe 607 can be connected to an external hot air source. After the pushing block 501 pushes the scraped hot melt adhesive into the through groove 602 through the connecting groove 601, the hot air generated by the hot air source can flow into the through groove 602 through the connecting pipe 607 and the air pipe 606, so that the hot melt adhesive in the through groove 602 can be kept in a liquid state, thus avoiding the phenomenon that the hot melt adhesive adheres to the inside of the through groove 602 and causes the through groove 602 to be blocked when flowing downward inside the through groove 602.

[0046] Through the above technical solutions: 1. By driving the extrusion assembly 3, the cardboard can pass through between the extrusion assemblies 3. During this process, the film can continuously adhere to the cardboard under the extrusion of the extrusion assembly 3. At the same time, during the rotation of the extrusion end, it can rotate past the blocking and scraping assembly 4, so that the scraping end of the blocking and scraping assembly 4 can scrape the hot melt adhesive attached to the extrusion end. This setting makes the surface of the extrusion end free of hot melt adhesive when it comes into contact with the cardboard and the film again, effectively avoiding the phenomenon that the hot melt adhesive accumulates and hardens on the extrusion end, resulting in unbalanced pressure distribution during the pressing of the extrusion end and scratching the surface of the film; 2. By arranging the upper scraping plate 401 to tilt upward, the phenomenon that the hot melt adhesive scraped by the upper scraping plate 401 falls onto the top of the cardboard again is avoided. At the same time, through the pushing motor 505, the screw 503 and the pushing frame 502, several pushing blocks 501 can push the hot melt adhesive accumulated on the upper scraping plate 401, so that the hot melt adhesive can move into the through groove 602 through the connecting groove 601 and directly fall into the collection box 604 under the guidance of the through groove 602. The above setting makes the scraped hot melt adhesive not accumulate on the upper scraping plate 401, thus ensuring the overall cleaning effect of the upper scraping plate 401.
