Description

Technical Field

[0001] The present invention relates to the technical field of paper composite processing devices, and particularly to a cooling device for a paper laminator. Background Art

[0002] The composite process of a laminator mainly realizes the tight bonding between materials through a ballast system. First, a continuous pressure is applied to the base material by a ballast roller and a pressurizing device to promote the formation of a uniform physical bonding interface between the materials. Subsequently, through hot pressing composite or pressure curing methods, and supplemented by a precise drying process to accelerate the volatilization of solvents. Finally, through a gradient cooling and shaping process to ensure the stable structure of the composite material. Among them, cooling and shaping, as the core link of quality control, realizes a uniform and stable temperature reduction process on the material surface through a temperature control system, which can effectively eliminate internal stress and stabilize the bonding force between composite layers, thereby significantly improving the composite strength and flatness of the product. When the existing paper laminator is in use, since multiple layers of paper pass through the ballast device, the layered materials are tightly bonded to each other. However, paper scraps or dust will adhere to the surface of the ballast roller, which will cause the material to deviate or local indentation. And after the hot melt adhesive or water-based adhesive solidifies, it adheres to the roller surface, which is time-consuming to clean and easy to damage the equipment. At the same time, after the cooling structure of the paper laminator is used for a long time, impurities will accumulate inside, which will affect the flow of the cooling liquid, resulting in a low water flow speed and insufficient water pressure inside the cooling structure, making the temperature distribution on the surface of the cooling roller uneven. Therefore, the cooling structure needs to be cleaned regularly to ensure the cooling effect. However, the existing cooling water pipeline structure is complex, and it is time-consuming and laborious to maintain and clean, which will lead to a high long-term use cost of the device.

[0003] Therefore, a cooling device for a paper laminator is needed to improve the above problems. Summary of the Invention

[0015] Compared with the prior art, the present invention can clean the composite pressure roller by arranging a cleaning component in the cooling device of the paper laminating machine. The scraper and the cleaning component work together to realize automatic impurity removal, wherein the scraper continuously scrapes off impurities on the surface of the composite pressure roller and accumulates them in the cleaning shell. At the same time, the control panel drives the servo motor to operate, and the rotational motion is converted into lateral reciprocating motion through the turntable crank lever and the limit plate. The mounting plate is pushed to swing around the limit axis through the connecting rod, the lever plate and the positioning rod, and the lever plate is driven to move back and forth on the inner wall of the cleaning shell, and finally the impurities are pushed into the aggregate shell through the connecting groove for centralized collection, thereby solving the problem that paper scraps or dust will adhere to the surface of the ballast roller, causing material deviation or local indentation, and the hot melt glue or water-based glue will adhere to the roller surface after solidification, which is time-consuming to clean and easy to damage the equipment.

The control panel drives the cooler to output cooling liquid to the rotating base, and the cooling liquid flows into the outer circulation shell provided with an annular partition through the connecting hole to form a cooling circulation water channel with stable flow. The dried paper strip conducts heat through the heat conduction plate at the cooling sleeve, and the internal circulation liquid pump drives the cooling liquid to flow in the heat exchange tube to absorb heat. The heated cooling liquid exchanges heat with the external circulation cooling liquid in the outer circulation shell. The system adopts the architecture of internal circulation closed heat absorption and external circulation open cooling water, optimizes the water channel flow rate through the annular partition, and finally guides the cooling water back to the cooler by the reflux device to complete the circulation, so as to realize uniform temperature distribution and efficient cooling of the paper strip, thereby solving the problem that the cooling structure of the paper compound machine will have impurities accumulated inside after long-term use, thereby affecting the flow of cooling liquid, and affecting the low water flow rate and insufficient water pressure inside the cooling structure, resulting in uneven temperature distribution on the surface of the cooling roller.

[0017] The present invention can facilitate cleaning and maintenance of the cooling structure by arranging a cooling component in the cooling device of the paper laminating machine. Since no external liquid flows through the heat exchange tube of the internal circulation, its interior always remains stable. The outer circulation shell can be pulled out of the cooling sleeve to clean the outer circulation shell. The coolant in the inner cavity of the outer circulation shell has a larger pipe diameter due to the structure of the annular partition and the device is easy to maintain, thereby solving the problem of regular cleaning of the cooling structure and ensuring the cooling effect. However, the existing cooling water pipeline structure is complicated, and maintenance and cleaning are time-consuming and labor-intensive, which will result in high long-term use costs of the device.

One end of the liquid guiding pipe 1014 is connected to the outer wall of the rotating base 1004. The liquid outlet of the reflux device 1003 is connected to the liquid inlet of the cooler 1002 through a connecting pipe.

[0024] Wherein, a limiting roller 13 is installed on one side of the composite pressing roller 7 and on the opposite inner walls of the fixed plate 2. The limiting roller 13 is rotatably connected to the fixed plate 2, and the limiting roller 13 and the composite pressing roller 7 are flush with each other. The limiting roller 13 is located on one side of the cleaning assembly 8. A stretching roller 14 is rotatably connected to the inner wall of the fixed plate 2 on one side of the collecting roller 12. A plurality of stretching rollers 14 are provided and are respectively located on the opposite inner walls of the fixed plate 2. Under the action that the control panel 3 is electrically connected to the servo motor 810, the dryer 9, the cooler 1002, the reflux device 1003, the driving motor 15 and the internal circulation liquid pump 1006 through wires, the device is powered on, and then the control panel 3 controls the servo motor 810, the dryer 9, the cooler 1002, the reflux device 1003, the driving motor 15 and the internal circulation liquid pump 1006 to operate. One end of the paper strip 6 is sequentially connected to the composite pressing roller 7, the limiting roller 13, the dryer 9, the cooling sleeve 1005, the stretching roller 14 and the collecting roller 12. The driving motors 15 are respectively arranged at one ends of the composite pressing roller 7 and the rotating shaft 11.

[0025] When the cooling device of the paper laminating machine of this scheme is working, the servo motor 810, the dryer 9, the cooler 1002, the reflow device 1003 and the internal circulation liquid pump 1006 are connected to the control panel 3 through the wires, and the connection mode is electrical connection, so that the device is powered on, and then the control panel 3 controls the servo motor 810, the dryer 9, the cooler 1002, the reflow device 1003, the drive motor 15 and the internal circulation liquid pump 1006 to operate, and at the same time, the drive motor 15 is operated. The driving motor 15 drives the rotating shaft 11 and the composite pressure roller 7, which causes the paper strip 6 to be transported. When the paper strip 6 passes through the composite pressure roller 7, it is rolled and composited. At the same time, when the paper strip 6 moves to the cleaning assembly 8, the limit spring 804 exerts downward pressure on the scraper 803, causing the scraper 803 to rotate on the outer wall of the rotating rod 802, causing the scraper 803 to fit the surface of the composite pressure roller 7. When the composite pressure roller 7 passes the scraper 803, The scraper 803 scrapes off the impurities on the surface of the composite pressing roller 7, and then the impurities are accumulated in the inner cavity of the cleaning shell 801. At the same time, the control panel 3 controls the servo motor 810 to operate. When the servo motor 810 operates, the drive shaft of the servo motor 810 drives the turntable 811 to rotate, and then the turntable 811 rotates through the crank lever 812, so that the crank lever 812 passes through the positioning groove 815 to toggle the limit plate 814. A positioning groove 815 is provided on the outer wall, so that the crank lever 812 exerts a lateral reciprocating movement on the limit plate 814, so that the limit plate 814 rotates on the outer wall of the rotating rod 813. When the limit plate 814 moves back and forth, the limit plate 814 drives the toggle plate 821 through the connecting rod 816, so that the toggle plate 821 moves back and forth laterally through the positioning rod 817, and slides on the outer wall of the positioning rod 817 to connect the limited groove 808, and the toggle plate 821 Under the action that one end of the cam is slidably connected to the inner wall of the limiting groove 805, when the toggle plate 821 moves, the positioning rod 817 will apply a thrust to the mounting plate 807 through the limiting groove 808. Since the limiting groove 808 and the positioning rod 817 are slidably connected, the positioning rod 817 slides on the outer wall of the limiting groove 808. At the same time, when the mounting plate 807 is subjected to the thrust, the mounting plate 807 will swing back and forth on the outer wall of the limiting shaft 806, thereby causing the mounting plate 807 to One end of the mounting plate 807 drives the paddle plate 809 to paddle the inner wall of the cleaning housing 801 back and forth, causing the paddle plate 809 to paddle the impurities in the inner cavity of the cleaning housing 801 to move to one side in sequence, thereby moving the impurities out through the connecting groove 820 and falling into the collecting housing 819 for collection. This solves the problem of paper scraps or dust adhering to the surface of the ballast roller, causing the material to deviate or form local indentations, and solves the problem of hot melt adhesive or water-based adhesive adhering to the roller surface after solidification, which is time-consuming to clean and easily damages the equipment. The cooler 1002 and the refluxer 1003 are controlled by the control panel 3 to operate. When the cooler 1002 operates, the cooled coolant is discharged into the inner cavity of the rotating base 1004 through the conduit 1013. Then, the cooling liquid enters the outer circulation housing 1009 through the communication hole 1010. An annular partition 1011 is provided on the inner wall of the outer circulation housing 1009. Under the action that the annular partition 1011 divides the outer circulation housing 1009 into the cooling circulation water channel 1012, the cooling liquid will flow in the cooling circulation water channel 1012. At the same time, the dryer 9 dries the paper strip 6. When the dried paper strip 6 moves to the cooling sleeve 1005, the heat of the paper strip 6 is conducted to the heat conduction plate 1008. At the same time, the control panel 3 controls the operation of the internal circulation liquid pump 1006. The internal circulation liquid pump 1006 circulates the coolant in the inner cavity of the heat exchange tube 1007. When the coolant in the heat exchange tube 1007 flows through the heat conduction plate 1008, the heat conduction plate 1008 conducts heat to the heat exchange tube 1007, thereby increasing the temperature of the coolant in the heat exchange tube 1007. When the heat exchange tube 1007 flows through the outer circulation housing 1009, the heat exchange tube 1007 conducts heat to the outer circulation housing 1009, thereby increasing the temperature of the coolant in the inner cavity of the outer circulation housing 1009. Since the cooling structure of the cooling assembly 10 is divided into internal circulation and external circulation, the temperature of the paper strip 6 is evenly distributed through the heat conduction plate 1008. Then, multiple groups of internal circulation heat exchange tubes 1007 absorb heat and cool down. Since there is no external liquid flowing through the heat exchange tubes 1007 in the internal circulation, the inside thereof always remains stable. At the same time, due to the structure of the annular partition 1011, the inner cavity of the outer circulation housing 1009 has a relatively large water channel diameter, which is convenient for the flow of water. The cooling structure is separated, and it will not affect the flow rate of the cooling water. Then, the coolant flows to the refluxer 1003 through the liquid guide pipe 1014. The refluxer 1003 discharges the cooling water into the cooler 1002 through the connecting pipe, thereby solving the problem that after the cooling structure of the paper laminating machine is used for a long time, impurities will accumulate inside, which will affect the flow of the cooling liquid, and will affect the low water flow rate and insufficient water pressure inside the cooling structure, resulting in uneven temperature distribution on the surface of the cooling roller; By disassembling the cooling component 10, since no external liquid flows through the heat exchange tubes 1007 of the internal circulation, the inside thereof remains stable all the time. Meanwhile, the outer circulation housing 1009 is inserted and removed on the inner wall of the cooling sleeve 1005. An annular communication hole 1010 is formed on the outer wall of the outer circulation housing 1009. Under the action of the inner cavity of the rotating base 1004 where the communication hole 1010 is located, when the outer circulation housing 1009 is pulled out of the cooling sleeve 1005, the outer circulation housing 1009 can be cleaned. Furthermore, due to the structure of the annular partition 1011, the inner cavity of the outer circulation housing 1009 has a relatively large water channel diameter, which is convenient for cleaning. The structure of the device is convenient for maintenance, thus solving the problem of regularly cleaning the cooling structure to ensure the cooling effect. However, the existing cooling water pipe structure is complex, time-consuming and laborious for maintenance and cleaning, which will lead to a relatively high long-term use cost of the device.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
