DETAILED DESCRIPTION

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the present application discloses a decorative paper adjustment mechanism.

[0036] Reference Figure 1 and Figure 2 The decorative paper adjustment mechanism includes a printing platform 1, and an adjustment component 2 and an attachment component 3 arranged on the printing platform 1. The adjustment component 2 includes a positioning member 21 and an adjustment member 22. The positioning member 21 is fixed on the top of the printing platform 1, and the adjustment member 22 is slidably arranged on the top of the printing platform 1. The adjustment member 22 moves in a direction close to or away from the positioning member 21. The printing platform 1 between the positioning member 21 and the adjustment member 22 is used to carry the decorative paper to be printed. The attachment component 3 includes a negative pressure device 31 and a plurality of adsorption ends 32 connected to the negative pressure device 31. The plurality of adsorption ends 32 are arranged on the top of the printing platform 1 and / or the second part 222 of the adjustment member 22, and are used to adsorb the decorative paper on the top of the printing platform 1, and cooperate with the adjustment component 2 to improve the positioning accuracy and stability of the decorative paper.

[0037] In this embodiment, there are two positioning members 21, and the positioning members 21 are plate-shaped structures. The two positioning members 21 are arranged perpendicular to each other, thereby forming two mutually perpendicular positioning reference coordinates. The circumference of the decorative paper abuts against the positioning members 21, and the decorative paper is preliminarily positioned from two directions. In other variant embodiments, multiple positioning members 21 can be used, and the shape of the positioning members 21 can be designed according to the contour shape of the sample paper of the decorative paper. The positioning members 21 can be set to be arc-shaped, wavy-shaped, irregular-shaped, etc., and the positioning members 21 can be replaced by plugging into the printing platform 1.

[0038] The printing platform 1 is provided with a slideway 11, the opening of the slideway 11 is arranged at one side of the top of the printing platform 1, the adjusting member 22 is slidably arranged in the slideway 11, and the adjusting member 22 partially protrudes from the opening of the slideway 11, and the adjusting member 22 moves along the slideway 11 toward or away from one of the positioning members 21 to drive the decorative paper to adjust its position. In this embodiment, there are two slideways 11, and one adjusting member 22 is slidably arranged in one group of slideways 11. The positioning members 21 correspond to the adjusting members 22 one by one, and one group of positioning members 21 and adjusting members 22 restricts one direction of the decorative paper, and the two groups of positioning members 21 and adjusting members 22 position and restrict the decorative paper from two directions perpendicular to each other, thereby improving the positioning accuracy of the decorative paper.

[0039] refer to Figure 3 and Figure 4 Specifically, the adjustment member 22 includes a first part 221 and a second part 222. The second part 222 is located in the slide 11, and the end face of the second part 222 is flush with the end face of the printing platform 1. A limiting groove 12 is provided inside the slide 11. The second part 222 protrudes with a limiting part 223 that cooperates with the limiting groove 12, and the limiting part 223 is slidably connected to the limiting groove 12.

[0040] The second part 222 has a cavity 224 built in, and a trigger member 23 and a locking member 28 are arranged in the cavity 224. The first part 221 has a first opening 225 facing the positioning member 21, and the first opening 225 is slidably connected to the cavity 224. The trigger member 23 moves relative to the adjustment member 22 along the length direction of the slideway 11. The trigger member 23 includes a first touch portion 231 and a second touch portion 232. The first touch portion 231 is arranged at the first opening 225 of the first part 221, and the second touch portion 232 is arranged in the cavity 224. A spring 25 is arranged in the adjustment member 22, and one end of the spring 25 is fixedly arranged on the inner wall of the adjustment member 22, and the other end is fixedly connected to the trigger member 23. The spring 25 is compressed or rebounded along the moving direction of the trigger member 23, that is, the spring 25 is extended and retracted along the length direction of the slideway 11. When only the elastic force of the spring 25 is acted upon, the first touch portion 231 protrudes from the first part 221.

[0041] The second portion 222 is provided with a second opening 226 toward the slide 11, and the second opening 226 is communicated with the cavity 224. The locking member 28 is rotatably connected to the cavity 224 via the rotating shaft 26. The rotating shaft 26 is sleeved with a torsion spring, one end of the torsion spring is fixedly connected to the interior of the second portion 222, and the other end is fixedly connected to the locking member 28. The torsion force of the torsion spring makes the locking member 28 have a tendency to rotate toward the interior of the slide 11. When the locking member 28 rotates to the second opening 226 and abuts against the inner wall of the slide 11, the friction between the locking member 28 and the inner wall of the slide 11 serves to limit the movement of the adjusting member 22.

[0042] Specifically, one end of the locking member 28 away from the rotating shaft 26 is a free end. In this embodiment, in order to enhance the locking state of the locking member 28 and the slide 11, the free end of the locking member 28 protrudes toward the slide 11 in a hook shape, and the inner wall of the slide 11 is provided with a plurality of grooves 13 that engage with the free end of the locking member 28, and the grooves 13 are distributed in an array along the length direction of the slide 11. When the locking member 28 engages with the grooves 13, the adjustment member 22 is locked with the printing platform 1. In a variant embodiment, the free end of the locking member 28 has a friction slope, and when the locking member 28 rotates toward the inner wall of the slide 11, the friction slope abuts against the inner wall of the slide 11, thereby increasing the contact area between the locking member 28 and the inner wall of the slide 11, so that the locking member 28 and the slide 11 are relatively stationary.

[0043] The second touch portion 232 is "L"-shaped, part of the second touch portion 232 is located in the cavity 224, and the other part is used to connect to the first touch portion 231. The part of the second touch portion 232 located in the cavity 224 is a plate-like structure, and this part slides along the direction of the slide 11. The translation path of the second touch portion 232 and the rotation path of the locking member 28 intersect at the second opening 226.

[0044] More specifically, the free end of the locking member 28 is provided with a guiding inclined surface 281, which is tangent to the second actuating portion 232. When the second actuating portion 232 moves toward the locking direction, the edge of the second actuating portion 232 moves along the guiding inclined surface 281, and the locking member 28 is disengaged from the groove 13. That is, the free end of the locking member 28 abuts against the second actuating portion 232, and the second actuating portion 232 separates the locking member 28 from the slideway 11 and supports the locking member 28.

[0045] The negative pressure device 31 is connected to a plurality of adsorption ends 32 through a hose 33. Specifically, the negative pressure device 31 is a negative pressure machine, and the adsorption end 32 is an air suction port or a negative pressure port. Preferably, a plurality of adsorption ends 32 are arranged in an array on the printing platform 1. Specifically, two adsorption ends 32 are arranged near the position between the two positioning members 21 to adsorb the portion of the decorative paper near the positioning members 21, and at least one adsorption end 32 is arranged on the printing platform 1 near the slide 11 to ensure that the decorative paper can be stably adsorbed on the printing platform 1.

[0046] Reference Figures 5 to 8More preferably, there are two slideways 11 corresponding to one positioning member 21, and the two slideways 11 are arranged in parallel, one of the slideways 11 is slidably provided with an adjustment member 22, and the other slideway 11 is provided with a suction member, the upper end surface of the suction member is flush with the upper end surface of the printing platform 1, and the suction member is provided with a suction end 32, and the suction end 32 is connected to the negative pressure device 31 through a hose 33. The bottom of the slideway 11 is provided with an opening so that the hose 33 can move with the suction member. The suction member adjustment member 22 is fixedly connected by a connecting rod 29, and the suction member moves parallel to the adjustment member 22, so that when the adjustment member 22 adjusts the position of the decorative paper, the suction member can firmly adsorb the decorative paper, avoiding the curling, shrinkage or wrinkles of the decorative paper during the position adjustment, thereby ensuring the accuracy of the printing of the decorative paper.

[0047] Reference Figure 1 A decorative paper adjustment mechanism also includes a carrier frame 4 and a frame 5. The frame 5 includes a slide rail 51 and a support frame 52. In this embodiment, there are two slide rails 51 and they are arranged in parallel with each other. A support frame 52 is fixedly arranged at both ends of the slide rail 51. The two support frames 52 are fixedly connected by a reinforcing rod 53. The carrier frame 4 is slidably connected to the slide rail 51. The printing platform 1 is fixedly connected to the top of the carrier frame 4. The top of the carrier frame 4 is flush with the top of the support frame 52. The circumference of the printing platform 1 extends outward from the carrier frame 4. That is, when the carrier frame 4 is close to one of the support frames 52, the top of the printing platform 1 and the support frame 52 partially overlap. The printing platform 1 is slidably plugged with a positioning pin 14. A positioning hole 54 is respectively provided near the two ends of the reinforcing rod 53. The printing platform 1 is plugged into the positioning hole 54 through the positioning pin 14 to realize the positioning of the printing platform 1.

[0048] The frame 5 is partially located at the printing port of the decorative paper printing machine, and partially located outside the decorative paper printing machine, that is, one of the support frames 52 is located at the bottom of the decorative paper printing machine. When the support frame 4 is far away from the decorative paper printing machine, the decorative paper with printing is placed on the printing platform 1, and the decorative paper is accurately positioned by the positioning member 21 and the adjusting member 22, and then the support frame 4 is pushed to feed the decorative paper to be printed into the bottom of the printing port of the printer, and the positioning pin 14 is inserted into the positioning hole 54 to position the printing platform 1 and wait for printing.

[0049] The implementation principle of Example 1 is as follows: after the operator places the decorative paper to be printed on the printing platform 1, the negative pressure device 31 is turned on. The negative pressure device 31 generates negative pressure on the adsorption end 32 through the hose 33, and the decorative paper is adsorbed on the printing plane, that is, the decorative paper is extended and laid flat on the printing platform 1. The operator pushes one of the adjustment members 22, and the first contact portion in the first part 221 abuts against the circumference of the decorative paper, and the top of the second part 222 supports the decorative paper, so that the adjustment member 22 moves along the length direction of the slide 11 toward the corresponding positioning member 21. Since the decorative paper is in the adsorbed state, the decorative paper has a certain rigidity in the thickness direction, which can ensure that it remains flat during the support movement. When one side of the decorative paper abuts against the positioning member 21 and the other side abuts against the adjustment member 22, the position of the decorative paper in this direction is determined, that is, the decorative paper is positioned in this direction. The operator continues to apply a thrust to the adjustment member 22 in the direction of the positioning member 21, and the decorative paper pushes the first contact portion to translate toward the inside of the first portion 221, compressing the spring 25, and the locking member 28 disengages from the second actuating portion 232, and the locking member 28 engages with the groove 13 on the slide 11, thereby locking the adjustment member 22 and locking the decorative paper in this direction. The two positioning members 21 are perpendicular to each other, that is, the two sets of structures lock the decorative paper in two vertical directions, and the adjustment component 2 cooperates with the attachment component 3 to accurately limit the decorative paper, ensuring that the printed pattern on the decorative paper is accurately aligned with the preset position, avoiding pattern offset or misalignment, and improving printing accuracy and clarity.

[0050] After the decorative paper printing is finished, the operator moves the carrier 4 out of the decorative paper printing machine and takes out the decorative paper. The pressure of the decorative paper on the trigger member 23 is removed. Under the action of the spring 25, the first touch portion 231 moves toward the outside of the first portion 221, and the second touch portion 232 moves relative to the guide slope 281 of the locking member 28, forcing the locking member 28 to rotate upward, and the locking member 28 is disengaged from the groove 13. The second touch portion 232 carries the locking member 28, and the adjusting member 22 can slide in the slideway 11.

[0051] This embodiment also provides a decorative paper printing machine, including a driving mechanism, a color paste system and a nozzle, wherein the nozzle is arranged at the output end of the driving mechanism, and the driving mechanism drives the nozzle to approach or move away from the decorative paper to be printed on the printing plane. The color paste system is connected to the nozzle, and the color paste system inputs the printing material into the nozzle to perform inkjet printing on the decorative paper.

[0052] A method for adjusting a decorative paper adjustment mechanism comprises the following steps: A1. After the decorative paper to be printed is placed on the printing platform 1, the negative pressure device 31 is turned on. The negative pressure device 31 generates negative pressure on the adsorption end 32 through the hose 33 to adsorb the decorative paper on the printing plane.

[0053] A2. Push one of the adjustment members 22. The first contact portion in the first part 221 abuts against the circumference of the decorative paper. The top of the second part 222 supports the decorative paper, so that the adjustment member 22 moves along the length direction of the slide 11 toward the corresponding positioning member 21. Since the decorative paper is in an adsorbed state, the decorative paper has a certain rigidity in the thickness direction, which ensures that it remains flat during the support movement. One side of the decorative paper abuts against the positioning member 21, and the other side abuts against the adjustment member 22. Continue to apply a thrust toward the positioning member 21 to the adjustment member 22. The decorative paper pushes the first contact portion to translate toward the inside of the first part 221, compressing the spring 25, and the locking member 28 disengages from the second actuating portion 232. The locking member 28 engages with the groove 13 on the slide 11, thereby locking the adjustment member 22. Push the other adjustment member 22 to lock the decorative paper in two vertical directions.

[0054] A3. Push the carrier 4 to the bottom of the printer, and insert the positioning pin 14 into the positioning hole 54 to lock the printing platform 1. The driving mechanism drives the nozzle to print the decorative paper.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
