[0039] Figure 1 A front view of a printing device for a PVC edge banding strip according to an embodiment of the present application is shown; Figure 2 A side view of a printing device for a PVC edge banding strip according to an embodiment of the present application is shown; Figure 3 Show Figure 2 A partial enlarged view of Figure 4 A main structural diagram of a printing device for PVC edge banding strips according to an embodiment of the present application is shown; Figure 5 A main structural diagram of a first deviation-correcting device and a second deviation-correcting device according to an embodiment of the present application is shown; Figure 6 A main structural diagram of a position regulator according to an embodiment of the present application is shown; Figure 7 The structure diagram of the printing device of the PVC edge banding strip of the embodiment of the present application is shown. Figure 1 As shown, the printing device of the PVC edge banding strip comprises: two conveying modules, more than two printing modules 200, a first deviation correcting device 400 and a first curing lamp 600; the conveying modules each comprise: an adjacently arranged active roller and a pressure roller, and the length direction of the active roller is parallel to the length direction of the pressure roller; the PVC edge banding strip 900 is suitable for sequentially passing through the active rollers and the pressure rollers of the two conveying modules; the first deviation correcting device 400, more than two printing modules 200, and the first curing lamp 600 are all arranged between the two conveying modules and arranged in sequence along the moving direction of the PVC edge banding strip 900; any printing module 200 comprises: an inkjet printer 210 and a second curing lamp 220 arranged in sequence along the moving direction of the PVC edge banding strip 900; the irradiation direction of the first curing lamp 600, the irradiation direction of the second curing lamp 220 and the inkjet direction of the inkjet printer 210 are all toward the same surface of the PVC edge banding strip 900.

[0040] Here, it should be noted that the two conveying modules are respectively the first conveying module and the second conveying module; the active roller 300 and the pressure roller 310 of the first conveying module are suitable for clamping one end of the PVC edge banding strip 900, and the active roller 800 and the pressure roller 810 of the second conveying module are suitable for clamping the other end of the PVC edge banding strip 900. The active roller 300 and the active roller 800 rotate at the same time to drive the PVC edge banding strip 900 to move, and control the PVC edge banding strip 900 to move forward at a stable speed. The first conveying module and the second conveying module clamp the PVC edge banding strip 900 at the same time and jointly drive the PVC edge banding strip 900 to move, which can effectively ensure the stability of the PVC edge banding strip 900 during movement, thereby ensuring the efficiency of the inkjet work. The first deviation correction device 400 is suitable for limiting the position of the PVC edge banding 900 before inkjet printing, so as to avoid the PVC edge banding 900 from being offset during the movement and affecting the inkjet effect; the inkjet printer 210 of the printing module 200 is suitable for inkjet printing on the PVC edge banding 900, and the second curing lamp 220 of the printing module 200 is suitable for baking and curing after the inkjet printer 210 inkjet printing. Each printing module 200 is fixed with a second curing lamp 220 beside the inkjet printer 210, which can be set at each After each inkjet printer 210 inkjet, it is dried in time, which effectively improves the fineness of the printed dots, especially makes the edges of graphics and texts sharper; after the inkjet printer 210 of the last printing module 200 completes the inkjet work, the PVC edge banding strip 900 moves to the bottom of the first curing lamp 600. The first curing lamp 600 is suitable for final curing of all the color inks printed after all printing modules 200 complete the inkjet of the PVC edge banding strip 900, further accelerating the fixing of the ink to achieve the required curing degree of the design. The overall structure of this application is compact and the functions are complete. It can cure the PVC edge banding strip 900 in time after each inkjet, with high curing efficiency and fast drying speed. It also makes the movement of the PVC edge banding strip 900 more stable during the inkjet process, effectively ensuring the efficient progress of the inkjet printing work, and has a wide range of applications. It is not only suitable for PVC edge banding strips 900, but also can be applied to the inkjet work of other materials.

[0041] In a possible implementation: it also includes: two support splints 100; two conveying modules and a first correcting device 400 are both arranged between the two support splints 100, and more than two printing modules 200 are movably connected to one of the support splints 100. Here, it should be noted that the two support splints 100 are suitable for providing installation positions and supports for components such as the two conveying modules, the first correcting device 400, the second correcting device 450 and the printing module 200, so that the PVC edge banding strip 900 can be printed after being fixed in the required position. Further, if Figure 4The main body of the two supporting splints 100 shown is a plate-like structure, and a connecting plate 110 is provided at the bottom of the two supporting splints 100. The connecting plate 110 is suitable for connecting and fixing the two supporting splints 100, thereby ensuring the position stability between the two supporting splints 100 and avoiding displacement between the two supporting splints 100 to affect the normal progress of inkjet operation.

[0042] The two ends of the active roller of each conveying module are inserted into the through holes of the supporting clamps 100 on both sides. Bearings are arranged between the active roller and the supporting clamps 100, so that the active roller can be rotatably installed between the two supporting clamps 100. Similarly, the pressure roller is also rotatably arranged between the two supporting clamps 100 through bearings. The PVC edge banding strip 900 passes between the active roller 300 and the pressure roller 310 and then between the active roller 800 and the driven roller 810. The active rollers 300 and 800 of the two conveying modules are both equipped with servo motors. The rotation of the output shafts of the two servo motors drives the active rollers 300 and 800 to rotate. Under the clamping action of the active roller 300 and the pressure roller 310, the edge banding strip can be stably moved. By controlling the speed difference of the two servo motors, simple tension control can be provided to ensure the stability of the tension of the PVC edge banding strip 900 under the printing module 200 and improve the printing accuracy.

[0043] Furthermore, two low-friction cylinders 320 are provided at both ends of the pressure roller 310, and the two low-friction cylinders 320 are respectively fixed on the side walls of the two supporting clamps 100, and the pistons of the low-friction cylinders 320 are connected to the pressure roller 310. The pressure of the low-friction cylinder 320 is adjustable, and the pressure of the low-friction cylinder 320 can be adjusted at any time to adjust the gap between the pressure roller 310 and the active roller 300, so that it can adapt to edge banding strips of various thicknesses. When the printing material is relatively thick, the pressure of the low-friction cylinder 320 can be reduced, the piston of the low-friction cylinder 320 will move up, and the pressure roller 310 will also move up to adapt to the increase in thickness. Similarly, two low-friction cylinders 320 are also provided at both ends of the pressure roller 810, and the pistons of the low-friction cylinders 320 are connected to the pressure roller 810. The pressure of the low-friction cylinder 320 can be adjusted at any time to adjust the gap between the pressure roller 810 and the active roller 800. Furthermore, the two ends of the pressure roller 310 and the two ends of the pressure roller 810 are connected to the two clamping plates 100 by passing through the through holes on the two clamping plates 100. In order to realize the movement of the two pressure rollers, the size of the hole needs to be larger than the size of the pressure roller, resulting in a certain amount of margin, ensuring that the pressure roller 310 and the pressure roller 810 can produce a slight displacement in the up and down directions, thereby realizing the control and adjustment of the gap between the pressure roller 310 and the active roller 300, and between the pressure roller 810 and the active roller 800.

[0044] Furthermore, the two conveying modules are at the same height on the supporting clamping plate 100 , that is, the distances between the two conveying modules and the connecting plate 110 are the same.

[0045] In a possible implementation, it further includes: a second deflection correction device 450; the second deflection correction device 450 is disposed between the first curing lamp 600 and the second conveying module. The first deflection correction device 400 and the second deflection correction device 450 have the same structure. The first deflection correction device 400 is suitable for limiting the position of the PVC edge banding strip 900 before inkjet printing, and the second deflection correction device 450 is suitable for limiting the position of the PVC edge banding strip 900 after inkjet printing, so as to avoid the PVC edge banding strip 900 from deflecting before and after inkjet printing, thereby further ensuring the inkjet effect.

[0046] In one possible implementation, Figure 5 As shown, the first correcting device 400 and the second correcting device 450 both include: a slide rail 410, more than two sliders 420 and the same number of baffles 430; both ends of the slide rail 410 are arranged on the inner side of the two supporting clamps 100 through a fixed seat 440, and each baffle 430 can be movably arranged on the slide rail 410 through each slider 420 and can move along the body length direction of the slide rail 410. More than two baffles 430 are suitable for being arranged on both sides of the PVC edge banding strip 900. Here, it should be noted that the two ends of the slide rail 410 are connected to the fixed seat 440, and the two sides of the fixed seat 440 can be fixed between the two supporting clamps 100 by bolt connection. The body length direction of the slide rail 410 is perpendicular to the moving direction of the PVC edge banding strip 900. A plurality of sliders 420 are installed on the slide rail 410, and the sliders 420 can slide on the slide rail 410. A baffle 430 is provided on the top of each slider 420. When the baffle 430 contacts the two sides of the PVC edge banding strip 900, the slider 420 is fixed on the slide rail 410, so as to fix the position of the baffle 430, so that the baffles 430 on both sides of the PVC edge banding strip 900 continuously limit the position of the PVC edge banding strip 900, and ensure that the PVC edge banding strip 900 does not deviate along a straight line during movement. It should be further explained that the number of sliders 420 is determined according to the number of PVC edge banding strips 900. Since the device can print one or more PVC edge banding strips 900 at the same time, multiple sliders 420 can be provided, as long as a baffle 430 is fixed on both sides of each PVC edge banding strip 900 to limit it.

[0047] In one possible implementation, each slider 420 is provided with a first tightening screw 421, one end of which passes through the slider 420 and abuts against the slide rail 410 inside the slider 420. The extent to which the first tightening screw 421 penetrates into the slider 420 is adjusted by rotating the first tightening screw 421. When the slider 420 moves to a desired position, the first tightening screw 421 is rotated to move the first tightening screw 421 toward the slide rail 410 until the first tightening screw 421 contacts the slide rail 410 and tightens the slide rail 410, thereby locking the slider 420. If the position of the slider 420 needs to be adjusted, the first tightening screw 421 is rotated in the opposite direction to loosen the slide rail 410.

[0048] Further, such as Figure 5 As shown, two sliders 420 are provided, and two baffles 430 are also provided. The two sliders 420 are manually adjusted to limit the PVC edge banding strip 900 within the printing area of ​​the printing module 200, to ensure that the movement direction of the PVC edge banding strip 900 will not be offset, and to prevent the PVC edge banding strip 900 from "drawing a dragon" under the printing module 200 when moving, thereby ensuring that the ink droplet landing point of each color is accurately overprinted, reducing overprint errors, and improving the quality of inkjet printing.

[0049] In a possible implementation, it also includes: an encoder meter wheel 500, which is arranged between the first deviation correction device 400 and the printing module 200. It should be noted that the meter wheel of the encoder meter wheel 500 is pressed on the PVC edge banding strip 900. When the PVC edge banding strip 900 moves forward, the meter wheel moves synchronously to provide an encoder signal to the printing module 200; the inkjet printer 210 prints the printing data sent by the host computer 1000 on the PVC edge banding strip 900 according to the pulse signal provided by the encoder. Furthermore, the encoder meter wheel 500 adopts a 5000-line differential encoder, combined with the encoder signal frequency doubling technology, which is convenient for setting multiple printing resolutions.

[0050] In a possible implementation, it also includes: more than two guide rollers 700; more than two guide rollers 700 are arranged between two conveying modules, more than two guide rollers 700 and more than two printing modules 200 are respectively located on opposite sides of the PVC edge banding strip 900, and the PVC edge banding strip 900 is in close contact with more than two guide rollers 700. It should be noted here that a plurality of guide rollers 700 are designed below the printing module 200 to ensure the smooth movement of the PVC edge banding strip 900, and the PVC edge banding strip 900 slides over the plurality of guide rollers 700 in sequence. The guide rollers 700 not only ensure the precise movement of the PVC edge banding strip 900, but also support the PVC edge banding strip 900 when the printing module 200 sprays ink on it, so as to avoid a large impact force on the PVC edge banding strip 900 during ink spraying, resulting in a reduction in tension. It should be noted here that the number of guide rollers 700 can be determined according to the distance between the two conveying modules and the number of printing modules 200.

[0051] Furthermore, if the distance between the nozzles of the inkjet printer 210 of each printing module 200 in the traveling direction of the PVC edge banding strip 900 is less than 200 mm, only two guide rollers 700 are required, and the PVC edge banding strip 900 is made parallel to the nozzle surface of the printing module 200, and the PVC edge banding strip 900 basically does not shake during movement; if the spacing is greater than 200 mm, an arc-shaped roller design is used, and a guide roller 700 is installed at a spacing of every 200 mm. Every two adjacent guide rollers 700 support the PVC edge banding strip 900 to form a plane, which is parallel to the nozzle surface of the inkjet printer 210 of the printing module 200 between the two guide rollers 700.

[0052] In a possible implementation, there are four printing modules 200. There are five guide rollers 700; one printing module 200 is provided between any two adjacent guide rollers 700. Figure 1 and Figure 7 As shown, the length directions of the five guide rollers 700 are parallel to each other and the five guide rollers 700 are arranged in an arc structure in sequence along the direction of the PVC edge banding strip 900. When the PVC edge banding strip 900 passes over the five guide rollers 700, four planes can be formed, and the four printing modules 200 are arranged directly above the four planes. In this way, a plane is aligned under the inkjet printer 210 of each printing module 200, and each guide roller 700 is in reliable contact with the PVC edge banding strip 900, reducing the up and down jumping of the PVC edge banding strip 900 during movement, thereby ensuring the quality of inkjet printing.

[0053] In a possible implementation, it further includes: a position regulator 230; the inkjet printer 210 is movably connected to the support clamp 100 through the position regulator 230, and the inkjet printer 210 can move along the body width direction of the PVC edge banding 900. It should be noted that in order to facilitate the adjustment of the inkjet position of the printing module 200 according to the width of the PVC edge banding 900, the position of the printing module 200 can be adjusted at any time by setting the position regulator 230. It is convenient to adjust the position of the inkjet printer 210 to match the printable area when producing PVC edge banding 900 of different widths.

[0054] In a possible implementation, the position regulator includes: a second slide rail 234, a slide rail seat 231, a second slider 233 and an adjustment portion; Figure 6 As shown, one side of the slide rail seat 231 is fixedly set on the supporting clamp plate 100, both ends of the two second slide rails 234 are fixedly set on the slide rail seat 231, the second slider 233 is slidably mounted on the two second slide rails 234, and the inkjet printer 210 of the printing module 200 is fixedly set on the side of the second slider 233 away from the slide rail seat 231. The inkjet printer 210 can follow the second slider 233 to move on the second slide rail 234, thereby adjusting the position of the inkjet printer 210 between the two supporting clamp plates 100, thereby adjusting the inkjet position of the inkjet printer 210.

[0055] In a possible implementation, the position regulator further includes: an adjustment hand wheel 235 and a lead screw 232; Figure 6 As shown, one end of the lead screw 232 passes through the slide rail seat 231 and is connected to the second slider 233, and the other end of the lead screw 232 is provided with an adjustment hand wheel 235. When the adjustment hand wheel 235 is rotated, the lead screw 232 can be rotated in the slide rail seat 231, thereby adjusting the extent of the lead screw 232 protruding into the slide rail seat 231 to achieve the advancement and retraction of the second slider 233 and thus adjust the position of the second slider 233. Here, it should be noted that compared with manual sliding adjustment, adjusting the position of the second slider 233 by rotating the lead screw 232 can effectively improve the adjustment accuracy. Furthermore, the adjustment hand wheel 235 and the lead screw 232 can also be replaced by a stepping motor or an electric cylinder to achieve electric control.

[0056] Further, such as Figure 6 As shown, a handle 236 is provided on the surface of the adjusting hand wheel 235 to improve the rotation convenience of the adjusting hand wheel 235 .

[0057] In one possible implementation, the position regulator also includes: a locking device. It should be noted that the locking device is suitable for locking and fixing the second slider 233 and the second slide rail 234 when the second slider 233 moves to the desired position, thereby preventing the second slider 233 from continuing to move on the second slide rail 234. Furthermore, the locking device includes: a rotating handle 238 and a second tightening screw 237, one end of the second tightening screw 237 passes through the second slider 233 and abuts against the second slide rail 234 inside the second slider 233, and the other end of the second tightening screw 237 is provided with a rotating handle 238, and the degree to which the second tightening screw 237 penetrates into the second slider 233 is adjusted by rotating the handle 238. When the second slider 233 moves to the desired position, the second tightening screw 237 is driven to rotate by rotating the rotating handle 238 so that the second tightening screw 237 moves toward the second slide rail 234 until the second tightening screw 237 contacts the second slide rail 234 and tightens the second slide rail 234, thereby realizing the locking of the second slider 233. If the position of the second slider 233 needs to be adjusted, the rotating handle 238 can be rotated in the opposite direction to release the second tightening screw 237 from the second slide rail 234.

[0058] In a possible implementation, there are more than two position regulators 230 , and each inkjet printer 210 is equipped with one position regulator 230 .

[0059] Here, it should be noted that the encoder meter wheel 500 may also be provided with a position regulator 230 as required to adjust the position of the encoder meter wheel 500 between the two clamping plates 100 .

[0060] In a possible implementation, the first curing lamp 600 and the second curing lamp 220 are both UV curing lamps, and the energy density of the first curing lamp 600 is greater than 16w / cm 2 The energy density of the second curing lamp 220 is greater than 16w / cm 2 The two ends of the first curing lamp 600 can be connected to the two clamping plates 100 by bolt fastening, and the side of the second curing lamp 220 can also be connected to the inkjet printer 210 by bolt fastening.

[0061] Since there are many types of PVC edge banding strips 900, with thickness ranging from 0.4mm-5mm and width ranging from 10mm-600mm, the winding route of the PVC edge banding strips 900 between the two supporting splints 100 is designed to be simple, such as Figure 7 As shown, the first wrap angle a and the second wrap angle b (i.e., the angle of the PVC edge strip 900 passing through the two conveying modules and entering and exiting the two active rollers) should be between 90-180 degrees to prevent the surface of the PVC edge strip 900 from being damaged when the angle is too large or too small.

[0062] In a possible implementation, the inkjet printer 210 is a UV printer; UV ink can better adapt to PVC materials, solidify firmly, and resist aging. The first curing lamp 600 and the second curing lamp 220 can also better dry it.

[0063] Working process of this application:

[0064] 1. Pull out a portion of the PVC edge banding strip 900 on the PVC edge banding strip coiling disc, and the PVC edge banding strip 900 passes through the first conveying module, more than two guide rollers 700, and the second conveying module in sequence, and is finally wound on the winding turntable and fixed firmly;

[0065] 2. After the system is powered on, the pressure roller 810 presses on the active roller 800, and the pressure roller 310 presses on the active roller 300;

[0066] 3. Move the blocking pieces 430 on the sliders 420 of the first deviation-correcting device 400 and the second deviation-correcting device 450 to the two sides of the PVC edge banding strip 900 , and fix the sliders 420 on the slide rails 410 .
