Technical Field

[0001] This invention relates to the field of flooring processing technology, and in particular to a flooring printing and laminating device. Background Technology

[0002] Chinese patent document CN213321813U discloses a film-applying and embossing device for flooring processing, comprising a base plate, with first support plates fixedly connected to the top of the base plate near the left and right sides respectively. A raw material roller is movably connected to the front wall of the first support plate on the left side near the top. Rotating wheels are respectively arranged inside the U-shaped plate near the left and right sides. Movable grooves matching the rotating wheels are respectively opened on the left and right side walls of the U-shaped plate. A first mounting block is installed at the bottom of the U-shaped plate near the left side. A second vertical plate is movably connected to the front and rear walls of the U-shaped plate near the right side via a rotating shaft and bearings. A first motor is installed at the top of the vertical plate near the left side. An embossing cylinder is movably connected to a third vertical plate via a rotating shaft and bearings. This utility model, through a series of structures, enables the device to have drying functions and simultaneously perform film-applying and embossing operations.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: The device lacks an effective tension adjustment structure during material conveying, and the substrate is not pre-treated before embossing, resulting in an unstable substrate surface condition. This leads to insufficient adhesion between the ink and the substrate, causing the printed pattern to easily peel off.

[0004] In summary, this application proposes a floor covering printing and laminating apparatus to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a flooring printing and laminating device that can solve the problems of lack of effective tension adjustment structure during material conveying, easy wrinkling due to loose base layer or stretching deformation due to excessive tension, affecting the accuracy of subsequent printing and lamination, and the lack of targeted pretreatment of base layer before embossing, resulting in unstable base layer surface condition, leading to insufficient adhesion between ink and base layer, and easy peeling off of printed patterns.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a floor covering printing and laminating device, characterized in that it comprises: The base plate has bracket one and bracket two fixedly installed on its top. The tensioning assembly is mounted on the base plate. The tensioning assembly includes a fixed frame, a U-shaped frame, a tensioning roller, and a threaded rod. The U-shaped frame is slidably mounted on the inside of the fixed frame, the tensioning roller is rotatably mounted on the inside of the U-shaped frame, and the threaded rod is rotatably mounted on the top of the U-shaped frame. The preheating component is set on the base plate. The preheating component includes a preheating box, an air outlet box, a connecting pipe, a horizontal pipe and a hot air blower. The air outlet box is fixedly installed on the top and bottom of the inner side of the preheating box. The hot air blower is connected to the air outlet box through the connecting pipe and the horizontal pipe. The pressure-bearing component is mounted on bracket 1 and bracket 2. The pressure-bearing component includes a connecting plate, a hydraulic rod, an I-shaped plate, a U-shaped frame 2 and a spring 1. The hydraulic rod is fixedly installed on the top of the connecting plate, and the free end of the hydraulic rod passes through the connecting plate and is fixedly installed on the I-shaped plate. The top of the U-shaped frame 2 is fixedly installed on the spring 1. The fixing component is set on the bracket and includes a placement frame, a connecting column, a T-shaped plug and a pull rod. The connecting column is set inside the placement frame. The T-shaped plug is slidably installed inside the pull rod. The outer wall of the connecting column has a slot. One end of the T-shaped plug passes through the pull rod and the placement frame and is snapped into the slot.

[0007] Preferably, a connecting plate is fixedly installed on one side of both the first and second brackets. One set of connecting plates is provided with an unwinding roller, and the other set of connecting plates is provided with a winding roller. The connecting plates provide stable support for the unwinding roller and the winding roller, ensuring the smoothness of the unwinding and winding process of the flooring base material and the finished product winding process, avoiding material conveying deviation due to unstable installation, and ensuring the continuity of the entire processing flow.

[0008] Preferably, the tensioning assembly further includes a slide rod, with a rotating plate fixedly installed at the top of the threaded rod through the fixed frame, and the slide rod fixedly installed at the top of the U-shaped frame. The top of the slide rod extends above the fixed frame, and the slide rod and the fixed frame are slidably installed. The threaded rod and the fixed frame are threadedly installed. Rotating the threaded rod can drive the U-shaped frame to rise and fall stably along the slide rod, so that the pressure of the tensioning roller on the base layer can be flexibly adjusted. This effectively avoids wrinkles caused by loosening of the base layer during transportation or stretching deformation caused by excessive tension, ensuring the flatness of the material in subsequent printing and lamination processes. The sliding cooperation between the slide rod and the U-shaped frame ensures the stability of the tensioning roller during the lifting process, avoids base layer displacement caused by uneven force, and improves the overall processing continuity and material utilization rate.

[0009] Preferably, there are two sets of preheating boxes, which are fixedly installed on the top of the base plate. The hot air blower is fixedly installed on the top of the base plate. The hot air generated by the hot air blower is transported to the air outlet boxes that are symmetrically distributed on the upper and lower surfaces through connecting pipes and horizontal pipes. Hot air can be blown from the upper and lower surfaces of the base layer at the same time to ensure that the base layer is heated evenly. This avoids material aging caused by local overheating or local insufficient temperature affecting the adhesion of subsequent printing. The surface of the base layer softens after preheating, which can significantly improve the bonding strength between the ink and the base layer, reduce the risk of the printed pattern falling off, and provide a stable material pretreatment effect for subsequent printing processes.

[0010] Preferably, auxiliary rollers are rotatably mounted on the inner walls of the front and rear sides of the first bracket, and a printing roller is provided on the first bracket. The auxiliary rollers and the printing roller correspond to each other. An upper pressure roller is rotatably mounted on the inner walls of the front and rear sides of the second bracket, and a lower pressure roller is provided on the second bracket. The upper pressure rollers and the lower pressure rollers correspond to each other. The auxiliary rollers and the printing rollers are correspondingly arranged to provide stable support for the printing of the base layer, ensure uniform printing pressure, improve pattern clarity, and ensure that the upper pressure rollers and the lower pressure rollers cooperate to ensure tight adhesion between the base layer and the film during lamination, thereby improving the composite effect.

[0011] Preferably, connecting plates are fixedly installed on the adjacent side walls of bracket one and bracket two. The lower pressure roller is rotatably installed on the front and rear inner walls of a set of U-shaped brackets two. The other end of spring one is fixedly installed on the bottom of the I-beam plate. A damper is provided inside spring one. Guide rods are slidably installed on both bracket one and bracket two. The bottom end of the guide rod is fixedly installed on the top of the I-beam plate. The hydraulic rod can precisely adjust the pressure, thereby adapting to the lamination requirements of flooring with different thicknesses, ensuring a tight bond between the base layer and the adhesive layer and the film. Spring one forms an elastic buffer against the pressure through U-shaped brackets two, avoiding damage to the base layer due to excessive instantaneous pressure. At the same time, it can compensate for slight fluctuations in material thickness, ensuring the pressure uniformity of the lamination and printing process, and improving the composite quality and pattern clarity.

[0012] Preferably, a support frame is fixedly installed on the adjacent sidewalls of the first bracket and the second bracket, and a coating roller is provided on the support frame. The support frame provides a stable installation base for the coating roller and ensures the stability of the coating roller when conveying coating material.

[0013] Preferably, the fixing assembly further includes a fixing frame and a second spring. There are two sets of placement frames, which are fixedly installed on the front and rear inner walls of another set of U-shaped frames. Connecting columns are fixedly installed on both the front and rear ends of the printing roller. A fixing frame is fixedly installed on one side of the placement frame. A pull rod is fixedly installed on one side of the T-shaped insert rod. The other end of the pull rod extends to the outside of the fixing frame. The second spring is sleeved on the pull rod. One end of the second spring is fixedly installed on one side of the T-shaped insert rod, and the other end of the second spring is fixedly installed on one side of the inner wall of the fixing frame. Under the elastic force of the second spring, the T-shaped insert rod is engaged in the slot of the connecting column, which can fix the printing roller on the second U-shaped frame. This facilitates quick replacement of printing rollers of different specifications, reduces downtime for material change, and improves the adaptability of the device to multi-variety production.

[0014] Preferably, a cold air box is fixedly installed on the top of the base plate. Two sets of cooling rollers are rotatably installed on the inner walls of the front and rear sides of the cold air box and are symmetrically distributed vertically. An opening is opened at the top of the cold air box, and a fan is fixedly installed inside the opening. A spiral cooling channel is opened inside the cooling roller. The two ends of the cooling channel extend to the outside of the cold air box and are connected to a circulating water pipe. The symmetrical cooling rollers, together with the internal spiral cooling channel, can fully contact the upper and lower surfaces of the flooring, accelerate heat conduction, and the fan blows cold air into the cold air box to form air convection, further improving the cooling efficiency and enabling the laminated flooring to cool down and set quickly, avoiding interlayer separation or pattern deformation caused by untimely cooling.

[0015] Preferably, guide rollers are provided on one side of both the preheating box and the cold air box. Both the preheating box and the cold air box have interconnecting through holes. One end of the unwinding roller and the winding roller extends to the outside of the connecting plate and is fixedly mounted with a drive motor. The output shaft of the drive motor is fixedly connected to the unwinding roller and the winding roller through a coupling. The guide rollers can guide the flooring, ensuring that the material passes stably through the preheating box and the cold air box along a preset path and avoiding deviation. The drive motor provides stable power to the unwinding roller and the winding roller. The coupling realizes precise power transmission, ensuring that the unwinding and winding speeds are matched and maintaining the stability of the processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The flooring printing and laminating device uses a fixed frame, a U-shaped frame, a tension roller, a threaded rod and a slide bar in combination. Rotating the threaded rod can drive the U-shaped frame to rise and fall steadily along the slide bar, so that the pressure of the tension roller on the base layer can be flexibly adjusted. This effectively avoids wrinkles caused by loosening of the base layer during the conveying process or stretching deformation caused by excessive tension, ensuring the flatness of the material in the subsequent printing and laminating processes. The sliding cooperation between the slide bar and the U-shaped frame ensures the stability of the tension roller's rising and falling process, avoids base layer displacement caused by uneven force, and improves the overall processing continuity and material utilization rate.

[0017] (2) The flooring printing and laminating device uses a preheating box, an air outlet box, a connecting pipe, a horizontal pipe and a hot air blower. The hot air generated by the hot air blower is transported to the air outlet box which is symmetrically distributed on the upper and lower sides through the connecting pipe and the horizontal pipe. Hot air can be blown from the upper and lower surfaces of the base layer at the same time to ensure that the base layer is heated evenly. This avoids material aging caused by local overheating or local insufficient temperature affecting the adhesion of subsequent printing. The surface of the base layer softens after preheating, which can significantly improve the bonding strength between the ink and the base layer, reduce the risk of the printed pattern falling off, and provide a stable material pretreatment effect for subsequent printing processes.

[0018] (3) The flooring printing and laminating device uses a connecting plate, hydraulic rod, I-beam plate, U-shaped frame 2 and spring 1 in combination. The hydraulic rod can accurately adjust the pressure, so as to adapt to the laminating requirements of flooring with different thicknesses, ensuring the tight bonding between the base layer and the adhesive layer and the film. Spring 1 forms an elastic buffer against the pressure through U-shaped frame 2, avoiding damage to the base layer due to excessive instantaneous pressure. At the same time, it can compensate for the slight fluctuations in material thickness, ensure the pressure uniformity of the laminating and printing process, and improve the composite quality and pattern clarity.

[0019] (4) The flooring printing and laminating device uses a combination of a placement frame, a connecting column, a fixed frame, a T-shaped insert, a spring, and a pull rod. The T-shaped insert is engaged in the slot of the connecting column under the elastic force of the spring, which can fix the printing roller on the U-shaped frame, making it easy to quickly change printing rollers of different specifications, reducing downtime for material change, and improving the adaptability of the device to multi-variety production.

Air outlet box 702 is fixedly mounted on the top and bottom of the inside of preheating box 701, and hot air blower 705 is connected to air outlet box 701 through connecting pipe 703 and horizontal pipe 704. 02 Connection; The pressure-bearing component 12 is disposed on the first bracket 2 and the second bracket 3. The pressure-bearing component 12 includes a connecting plate 1201, a hydraulic rod 1202, an I-shaped plate 1203, a second U-shaped frame 1204, and a first spring 1205. The hydraulic rod 1202 is fixedly installed on the top of the connecting plate 1201. The free end of the hydraulic rod 1202 passes through the connecting plate 1201 and is fixedly installed on the I-shaped plate 1203. The top of the second U-shaped frame 1204 is fixedly installed on the first spring 1205. 5; The fixing component 14 is set on the bracket 2. The fixing component 14 includes a placement frame 1401, a connecting column 1402, a T-shaped insert 1404 and a pull rod 1406. The connecting column 1402 is provided inside the placement frame 1401. The T-shaped insert 1404 is slidably installed inside the pull rod 1406. A slot is opened on the outer wall of the connecting column 1402. One end of the T-shaped insert 1404 passes through the pull rod 1406 and the placement frame 1401 and is snapped into the slot.

[0024] Furthermore, connecting plates 4 are fixedly installed on one side of both bracket 1 2 and bracket 2 3. One set of connecting plates 4 is equipped with unwinding rollers 5, and the other set of connecting plates 4 is equipped with take-up rollers 19. The connecting plates 4 provide stable support for the unwinding rollers 5 and take-up rollers 19, ensuring the stability of the unwinding and take-up process of the flooring base material roll, avoiding material conveying deviation due to unstable installation, and ensuring the continuity of the entire processing flow.

[0025] Furthermore, the tensioning assembly 6 also includes a slide rod 605. The top end of the threaded rod 604 passes through the fixed frame 601 and is fixedly mounted with a rotating plate. The top of the U-shaped frame 602 is fixedly mounted with the slide rod 605. The top end of the slide rod 605 extends above the fixed frame 601. The slide rod 605 and the fixed frame 601 are slidably installed. The threaded rod 604 and the fixed frame 601 are threadedly installed. Rotating the threaded rod 604 can drive the U-shaped frame 602 to rise and fall stably along the slide rod 605, so that the pressure of the tensioning roller 603 on the base layer can be flexibly adjusted. This effectively avoids wrinkles caused by loosening of the base layer during transportation or stretching deformation caused by excessive tension, ensuring the flatness of the material in subsequent printing and lamination processes. The sliding cooperation between the slide rod 605 and the U-shaped frame 602 ensures the stability of the tensioning roller 603 during the rising and falling process, avoids base layer displacement caused by uneven force, and improves the overall processing continuity and material utilization rate.

[0026] Furthermore, there are two sets of preheating boxes 701, which are fixedly installed on the top of the base plate 1. The hot air blower 705 is fixedly installed on the top of the base plate 1. The hot air generated by the hot air blower 705 is delivered to the air outlet box 702, which is symmetrically distributed on the upper and lower surfaces, through the connecting pipe 703 and the horizontal pipe 704. Hot air can be blown from the upper and lower surfaces of the base layer at the same time to ensure that the base layer is heated evenly and avoid material aging caused by local overheating or the impact of local insufficient temperature on the adhesion of subsequent printing. The surface of the base layer softens after preheating, which can significantly improve the bonding strength between the ink and the base layer, reduce the risk of the printed pattern falling off, and provide a stable material pretreatment effect for subsequent printing processes.

[0027] Furthermore, auxiliary rollers 8 are rotatably installed on the inner walls of the front and rear sides of bracket 2, and printing rollers 9 are set on bracket 2. Auxiliary rollers 8 and printing rollers 9 correspond to each other. Upper pressure rollers 10 are rotatably installed on the inner walls of the front and rear sides of bracket 3, and lower pressure rollers 11 are set on bracket 3. Upper pressure rollers 10 and lower pressure rollers 11 correspond to each other. Auxiliary rollers 8 and printing rollers 9 are set in a corresponding manner to provide stable support for the printing of the base layer, ensure uniform printing pressure, and improve the clarity of the pattern. The corresponding cooperation between upper pressure rollers 10 and lower pressure rollers 11 can ensure the tight adhesion between the base layer and the film during lamination and improve the composite effect.

[0028] Secondly, connecting plates 1201 are fixedly installed on the adjacent side walls of bracket 12 and bracket 23. The lower pressure roller 11 is rotatably installed on the front and rear inner walls of a set of U-shaped brackets 2204. The other end of spring 1205 is fixedly installed on the bottom of the I-shaped plate 1203. A damper is provided inside spring 1205. Guide rods 1206 are slidably installed on both bracket 12 and bracket 23. The bottom end of the guide rod 1206 is fixedly installed on the top of the I-shaped plate 1203. The hydraulic rod 1202 of the pressure-bearing component 12 pushes the I-shaped plate 1203 downward, so that the printing roller 9 and the lower pressure roller 11 press against the base layer. At the same time, the spring... Spring 1205 buffers the pressure through U-shaped frame 2 1204. The embossed pattern on the surface of the printing roller 9 contacts the base layer, and the ink is transferred to the base layer surface through pressure to complete the pattern printing. The hydraulic rod 1202 can precisely adjust the pressure, so as to adapt to the lamination requirements of flooring with different thicknesses, ensuring a tight bond between the base layer and the adhesive layer and the film. Spring 1205 forms an elastic buffer against the pressure through U-shaped frame 2 1204, avoiding damage to the base layer due to excessive instantaneous pressure. At the same time, it can compensate for slight fluctuations in material thickness, ensure the pressure uniformity of the lamination and printing process, and improve the composite quality and pattern clarity.

[0029] Secondly, support frames are fixedly installed on the adjacent side walls of bracket 1 2 and bracket 2 3. A coating roller 13 is mounted on the support frame, providing a stable mounting base for the coating roller 13 and ensuring its stability when conveying coating material. The fixing assembly 14 also includes a fixing frame 1403 and a spring 2 1405. Two sets of placement frames 1401 are fixedly installed on the front and rear inner walls of another set of U-shaped frames 2 1204. Connecting columns 1402 are fixedly installed at both the front and rear ends of the printing roller 9. A fixing frame 1403 is fixedly installed on one side of the placement frame 1401, and a pull rod 1406 is fixedly installed on one side of the T-shaped insert 1404. The other end of the pull rod 1406 extends to the outside of the fixing frame 1403. Spring 1405 is sleeved and installed on pull rod 1406. One end of spring 1405 is fixedly installed on one side of T-shaped insert rod 1404, and the other end of spring 1405 is fixedly installed on the inner wall of one side of fixed frame 1403. When it is necessary to replace the printing roller 9, pull pull rod 1406 outward to move T-shaped insert rod 1404 away from the slot on connecting column 1402, and the printing roller 9 can be taken out. Under the elastic force of spring 1405, T-shaped insert rod 1404 is engaged in the slot of connecting column 1402, which can fix the printing roller 9 on U-shaped frame 1204, which facilitates quick replacement of printing rollers 9 of different specifications, reduces downtime for material change, and improves the adaptability of the device to multi-variety production.

[0030] Finally, a cold air box 15 is fixedly installed on the top of the base plate 1. Two sets of cooling rollers 17 are rotatably installed on the inner walls of the front and rear sides of the cold air box 15 and are symmetrically distributed vertically. An opening is opened at the top of the cold air box 15, and a fan 16 is fixedly installed inside the opening. A spiral cooling channel is opened inside the cooling roller 17, and the two ends of the cooling channel extend to the outside of the cold air box 15 and are connected to circulating water pipes. The film-coating roller 13 conveys the film between the upper pressure roller 10 and the lower pressure roller 11. The downward movement of the I-beam plate 1203 causes the upper pressure roller 10 to press the film and the base layer tightly. The film-coated floor covering enters the cold air box 15. The cooling water inside the cooling roller 17, together with the cold air blown by the fan 16, rapidly reduces the material temperature to room temperature, so that the interlayer structure is cured and shaped. The vertically symmetrical cooling rollers 17, together with the internal spiral cooling channel, can fully contact the upper and lower surfaces of the floor covering, accelerating heat conduction. The fan 16 Cold air is blown into the cold air box 15 to create air convection, further improving cooling efficiency and allowing the laminated flooring to cool and set quickly, preventing interlayer separation or pattern deformation due to untimely cooling. Guide rollers 18 are provided on one side of both the preheating box 701 and the cold air box 15. Both the preheating box 701 and the cold air box 15 have connecting through holes. One end of the unwinding roller 5 and the winding roller 19 extends to the outside of the connecting plate 4 and is fixedly mounted with a drive motor. The output shaft of the drive motor is fixedly connected to the unwinding roller 5 and the winding roller 19 through a coupling. The guide rollers 18 can guide the flooring, ensuring that the material passes stably through the preheating box 701 and the cold air box 15 along a preset path, avoiding deviation. The drive motor provides stable power to the unwinding roller 5 and the winding roller 19, and the coupling realizes precise power transmission, ensuring matching of unwinding and winding speeds and maintaining the stability of the processing.

[0031] Working principle: During use, the unwinding roller 5 releases the flooring base material roll. The tension is adjusted by the tensioning component 6. Rotating the threaded rod 604 drives the U-shaped frame 602 to move up and down along the slide rod 605, so that the tensioning roller 603 presses the base material tightly, preventing wrinkles or loosening during transportation. The base material enters the preheating box 701. The hot air generated by the hot air blower 705 is transported to the air outlet box 702 through the horizontal pipe 704 and the connecting pipe 703. The air outlet box 702 blows the hot air evenly onto the surface of the base material to preheat it. The preheated base material passes between the auxiliary roller 8 and the printing roller 9. The hydraulic rod 1202 of the pressure bearing component 12 pushes the I-shaped plate 1203 down, so that the printing roller 9 and the lower pressure roller 11 press the base material tightly. At the same time, the spring 1205 buffers the pressure through the U-shaped frame 1204. The concave and convex patterns on the surface of the printing roller 9 come into contact with the base material, and the pressure is applied by the pressure roller 1205. The ink is transferred to the base surface to complete the pattern printing. The printed base layer enters between the upper pressure roller 10 and the lower pressure roller 11. At the same time, the laminating roller 13 conveys the film between the upper pressure roller 10 and the lower pressure roller 11. The downward movement of the I-beam plate 1203 causes the upper pressure roller 10 to press the film and the base layer tightly. The laminated flooring enters the cold air box 15. Cooling water circulates inside the cooling roller 17. With the help of the cold air blown by the fan 16, the material temperature is quickly reduced to room temperature, so that the interlayer structure is solidified and shaped. The cooled finished product is guided by the guide roller 18 to the take-up roller 19. The take-up roller rotates stably under the drive of the drive motor, rolling the flooring into a neat roll to complete the processing. When it is necessary to replace the printing roller 9, the pull rod 1406 is pulled outward to move the T-shaped insert 1404 away from the slot on the connecting column 1402, so that the printing roller 9 can be taken out.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
